THE PROGNOSIS OF INTERNAL DISEASES BY HENRY L. JELSNER, M.D., LL.D. PROFESSOR OF MEDICINE, COLLEGE OF MEDICINE, SYRACUSE UNIVERSITY NEW YORK AND LONDON D. APPLETON AND COMPANY 1923 Copyright, 1916, 1923, by D. APPLETON AND COMPANY Printed in the United States erf America TO MY WIFE MY MOST CHARITABLE AND PATIENT CRITIC AND CONSTANT INSPIRATION “But the power of prognosis is at once the most complete and the most easily understood proof of the reality of knowledge. As soon as an eclipse could be correctly predicted, astronomy was proved to be a true science; and, particularly, we find that nothing so much secures the confidence of patients as a prediction which proves true” (Pye-Smith). Preface The prognosis of a disease presupposes a full knowledge of the disease in respect to its etiology, pathology and clinical manifestations. A review of the present edition reveals how logically the author has portrayed diseases from the viewpoint of prognosis. Ilis wide clinical experience and extensive knowledge of the literature made possible the creation of a work of this nature. Consciously or unconsciously the question of prognosis enters into the consideration of all disease. It was the desire of the author to place before his readers this phase of medicine for its guiding influence towards a broader horizon. Charles D. Post 212 Physicians’ Bldg., Syracuse, N. Y. Preface The purpose of this book is to bring reassurance and comfort to the physician, and through him greater benefit to the patient. The study of prognosis begets confidence. “He heals best who is most certain of the course of disease.” This is an aphorism which is incontrovertible; hence the physician who would give a reliable forecast of disease is at once forced to a consideration of underlying conditions. He must think clearly, must have a fundamental knowledge of physiologic processes, must study the perversion of these— pathologic conditions—must be able to interpret the meaning of sub- jective and objective manifestations, must be able to determine the re- ciprocal relations of Constitution, Resistance and Heredity; he must view the body as a whole and he must recognize the fact that medical prog- nosis is exceedingly complex and therefore demands the consideration of multiple data. Medical 'prognosis includes the scientific survey of the entire field of Medicine. The author and the publishers hope that this work on “The Prog- nosis of Internal Disease,” the first systematic treatise on this subject to be presented to the medical profession, will stimulate the workers in the field of medicine to the acquisition of such fundamental knowledge as is needed for the reliable forecast of disease as it presents in practice. These facts, and the study of the meager literature of the subject of Prognosis, have encouraged the author during the many years of his pro- fessional activity to accumulate the material upon which his conclusions are based, and finally to launch this work. The author fully appreciates the fact that the study of medical prog- nosis must often forcibly impress the profession with the limitations of its art; on the other hand, it is made conscious of the possibilities of medicine by the association of pathologic knowledge with keen diagnostic and thera- peutic ability, tempered with tact and the humane spirit of the true physician. The enormous advances which have resulted from animal experimenta- tion, including vivisection, and the refinements of diagnosis aided by the newer sciences, particularly bacteriology, have completely changed our conception of many diseases. PREFACE The devotion of a band of unselfish and patient workers in the labor- atories and among the infected in far-off countries, many of whom wel- comed hardships and even sacrificed their lives that medical truths might be established, has led to the prevention of some diseases and favorably changed the forecast of others. The author has aimed to establish the urgent necessity in practice of correlating all available knowledge that safe conclusions for diagnosis, prognosis, and treatment may be reached, and he has sought to impress the further fact that the practical physician must brace himself against one-sided reasoning, and always place the greater reliance upon the subjective and objective features of the individual case, to which he should add (and aim to interpret correctly) the results of laboratory investigation. The author wishes to express his appreciation of the confidence which during more than a third of a century has been extended to him by his professional colleagues. Without their support this book would have been impossible. Their friendship and encouragement have been important factors in leading him to the completion of this monumental task. To the publishers, the author extends his thanks and his appreciation for their uniform courtesy and material assistance. To the reader, the author delivers the following pages with the hope that they will often reassure, comfort and stimulate him. If his friends and the readers find only a fraction of the pleasure in the study of “The Prognosis of Internal Disease” that the author has enjoyed during the years of its production, he will feel sufficiently re- warded.

Prognosis is the 'prescience of disease, the art of foretelling the progress and termination of disease. The foreknowledge thus obtained is included in the term uprognosis.” Prognosis, therefore, includes a forecast of the patient’s future, not only whether the disease is curable, but how long under existing conditions life may be prolonged, what influence the disease is likely to have on his activities and the enjoyment of life, what factors may lead to its advance and what will influence its course favorably; hence it stimulates rational treatment. Leyden has truthfully said “Prognosis represents the very quint- essence of the physician’s knowledge.” The literature which has accumulated on the subject of the Prognostics of Disease, is comparatively meager. (See Bibliography appended, and full literature in Volumes XI, 1st Series, and XIII, 2nd Series, Index Catalogue of the Library of the Surgeon-General’s Office, United States Army). The history of medicine proves that the disciple of our art Hippocrates, was more concerned with the prognostics of disease than with any other question connected with its study. Prognosis became the first object of all Theory connected with Medicine. “A glimpse into ancient medical literature shows that more space was devoted to the Prognostics of Disease than is occupied for a similar purpose in the modern compendium” (Xeuburger). It is a fact that formerly, prognosis was made without accurate diagnosis, without patho- logic knowledge; today prognosis is based not only on subjective symp- toms but upon the results of thorough physical examination, the con- sideration of pathologic conditions, the revelations of the laboratory and a well digested previous history—a consideration of all of the features made clear by thorough investigation. This is not all as we shall see; the paramount facts are also offered by the picture which the patient 1 2 THE PROGNOSIS OF INTERNAL DISEASE presents. A projection upon the diagnostic screen is made, not from the study of text books or monographs, but as a result of years of experience, painstaking analysis and correct reasoning. Prognosis is often made without accurate diagnosis or positive knowl- edge of the anatomic lesions, and yet it proves fairly valuable for the immediate future in important cases, pending the acquisition of exact knowledge gained from further study of the individual case. Hippocrates3 rules of practice were based on experience; he was, as his critics have said “the physician of experience and common sense.” “What he appears to have studied with particular attention is the natural history of diseases, that is to say, their tendencies to a favorable or fatal issue; and without this knowledge, what can all medical practice be hut blind empiricism ?” . . . “The physician who cannot inform his patient what would be. the probable issue of his complaint, if allowed to follow its natural course, is not qualified to prescribe any rational plan of treat- ment for its cure” (Francis Adams). Hippocrates was fully conscious of the fallaciousness of experience and “therefore never exempts the ap- parent results of experience from the strict scrutiny of reason.” To prove this great truth he made the following, the first of his aphorisms:— Aphorisms of Hippocrates (I) :— “Life is short, and the Art long; the occasion fleeting; experience falla- cious, and judgment difficult. The physician must not only he prepared to do what is right himself, hut also to make the patient, the attendants, and externals co-operate.” Galen’s Commentary on this aphorism shows that he interpreted it as meaning “The occasion is fleeting, experiment is dangerous and decision is difficult.” Galen remarks that it is “hazardous to experiment in a case which involves the life of a human being, and that it is difficult to catch the truth in medicine, as is evident from the circumstances of the profession being divided into so many opposite sects” (Adams). Hippocrates was conscious of the power of Nature to cure disease. He upheld the principle that “Nature is the physician of diseases’’ (Hippo- crates). “Nature although untaught and uninstructed does what is properSydenham placed his stamp of approval upon these philosophical tenets by quoting them frequently, while Galen’s Commentary remains a classic, full of interesting and profitable data, “a fine specimen of the medical philosophy of the ancients.” . Herophilus (300 a. d.) was the first commentator on Hippocrates of whom we have any record; unfortunately his Commentaries were never preserved so far as we know. He was also the first to study the character of the pulse. GENERAL CONSIDERATIONS 3 It is of interest to note that no mention is made in the “Books of the Epidemics” on the characters of the arterial pulse and contagion. Hippo- crates, as well as his contemporary Thucydides, must have appreciated the contagiousness of the plague which the latter described clearly, and taught that the disease was contagious. Adams’ conclusions concerning the authenticity of the works of “The Father of Medicine” may be accepted as being as near the truth as we can ever hope to get: 1. “All the authorities, ancient and modern, who have investigated the question regarding the genuineness of the works which have come down to us under the name of Hippocrates, are agreed that a considerable portion of them are not the production of the author himself.” 2. “It is almost universally admitted that the following treatises are genuine, viz:— The Prognostics On Airs, et cetera On Regimen in Acute Disease Seven of the Books of Aphorisms Epidemics I and III On the Articulations On Fractures On the Instruments of Reduction The Oath” Adams further holds that it may be conceded with considerable cer- tainty that the following treatises are genuine though the “evidence in their favor is not so strong as it is with regard to the preceding list On Ancient Medicine On the Surgery The Hand On Ulcers On Fistulae On Hemorrhoids On the Sacred Diseases” The first “Prorrhetics” and the “Coacae probably ante- dated the time of Hippocrates. “It appears to me a most excellent thing for |(fljfcphysician to cultivate prognosis; for by foreseeing and foretelling i:r»T|(||eresence of the sick, the present, the past, and the future, and expMfl$®lhe omissions which patients may have been guilty of, he will be ,’e readily believed 4 THE PROGNOSIS OF INTERNAL DISEASE to be acquainted with the circumstances of the sick, so that men will have confidence to entrust themselves to such a physician. And he will manage the case best who has foreseen what is to happen from the present state of matters” (Hippocrates). The Book of the Prognostics continues the most learned systematic consideration of the subject which was included in fragmentary references to but few individual diseases until 1G01 when Prosper Alpinus, Pro- fessor of Medicine at Padua, published a most remarkable dissertation on Prognostics “in confirmation of the Hippocratic method” with the title “De Praesagienda Vita et Morte Aegrotantium,” in seven volumes. The work was translated by R. James, M.D., and published in London in 1746 with an introduction by the renowned Boerhaave, taken from an edition of Alpinus published in Leyden in 1709. Since that day there has been no attempt to present a systematic work by a single clinician dealing with the leading feature of all internal diseases which bear upon their prognosis. J. Harvey published his “Praesagium Medicum or the Prognostick Signs of Acute Diseases, Established by Antient Observation and Ex- plained by the Best modern Discoveries” in London in 1706; a work which created a sensation in the profession. The leading publications dealing with the separate consideration of the prognostics of disease during the nineteenth century were “Traite Ele- mentaire de Diagnostic de Prognostic, et cetera,” par Leon Rostan, Paris 1830; Cyclopedia of Practical Medicine, Vol. III., article “Prognosis” by Edward Ash, London 1834; a unique article “On Prognosis,” by William Farr, in the British Medical Almanack, 1839; “Observations of Prognosis” Vol. XLIV, Guy’s Hospital Report 1887, P. H. Pye- Smith, and another article by Pye-Smith: “Observations upon Certain Elements in General Prognosis, upon the Particular Prognosis of Phthisis and of Enteric Fever.” An oration on Prognostics was deliv- ered before the Hunterian Society of London in 1858 by Doctor Munk, from which the following is quoted to add the valuable included his- toric data:— “Coincidently with the return from the polluted stream of Arabian Medi- cine to the pure fountain of Grecian physic, was the renewed cultivation of a rational and scientific prognosis. It was in connection with a humoral pathology that prognosis made the greatest progress and achieved its highest triumphs.” “The doctrines of solidism on the other hand have uniformly proved inimical to the study of prognosis” “Prognosis was but little regarded by Hoffman, and still less by Cullen. To the neglect it experienced from the luminary of the Edinburgh School, its decadence in this country (England) is to be attributed. The pupils of Boerhaave and of the school over which this name and example con- tinued to shed luster, were still cultivating prognosis in all its minutiae, GENERAL CONSIDERATIONS 5 and applying its rules with startling accuracy at the very time when Cullen’s genius blazed above the medical horizon; and it was not until these had died off, and Edinburgh had taken that place in public esti- mation as a medical school, which Leyden had previously enjoyed, that the regular minute and systematic study of a rational prognosis became extinct in this country.” Dyce Duckworth in the paragraph following the above which he also quotes, writes: “I think that just consideration of the prevailing doctrines of pathology at the present time may encourage us to hope that renewed attention and study may henceforth be directed to the subject of prog- nostics.” Reynolds in his System of Medicine in 1866 declared “the practical test of a true science is the power which it confers of ‘prevision’ or knowing what will follow hereafter.” “When we can prognosticate with certainty, medicine will have become a science” “Life is too subtle for us to know or measure all its possible contingencies.” The more recent English publications include the classic contributions of Sir Dyce Duckworth (London 1896)—from whom, for these General Considerations I have gained many facts; the oration of George Dock on “Prognosis, Its Theory and Practice” (The Journal of the American Medical Association, 1904). In German, Franke’s “Lehre von der Bedeu- tung des Pulses und die Respirations Frequenz fiir die Prognose acuter fieberhafter Krankheiten” (Beitr. z. Pathol, u. Physiol., Berlin, 1878, III., p. 303) remains a classic in medical literature. They also include C. Gerhardt’s “Leber Vorhersage am Krankenbette (Munch. Med. Woch- enschr., Hov. 24, 1896) ; the contribution of Moritz E., “Ueber Lebens Prognose,” 1905; an article by Neuburger, “Zur Entwicklungsgeschichte der Prognostik” (Wiener Med. Presse, 1907) ; and the brochure of Nor- bert Ortner on “Klinische Prognose,” Wien, 1908. Short, in England, with the assistance of over twenty clinicians has edited an Index of Prognosis which includes surgical affections (London and Hew York, 1915). The eloquent Address in Medicine, on Medical Prognosis, delivered by Chauffard at the Seventeenth International Congress of Medicine (London 1913) has awakened anew the interest in the Presage of Disease. Chauf- fard clearly demonstrated that the paths to prognosis are open by the study of morbid disturbances, and by the “analytical method with the help of a more and more penetrating technique.” For safe prognosis we assume that pathology is but perverted or, as Chauffard says, “deviated” physiology, and disease, a disturbance of nor- mal functions. We must associate with our knowledge of pathology a thor- ough acquaintance with the resulting functional disturbances. But while we gauge the result of disease on the various functions of disturbed organs there are innumerable factors which influence the prognosis of disease. 6 THE PROGNOSIS OF INTERNAL DISEASE Exogenous and endogenous influences must be considered. The defensive reaction of the blood and the cellular elements to bac- terial contamination and mechanical insult, the prompt alignment of the protective forces against the invading army, become at once factors with which the prognostician must rechon. There are factors of which we are still uncertain which lead to the formation of antibodies, stimulate cellular elements to activity and increase, provide the blood with opsonins and other protective substances, produce protective exudates, stimulate Organs to compensatory action, promptly arouse the innumerable “factors of safety” which are present in almost all of our organs (Meltzer), and light to activity that innate, indefinable resistance which is so prominent in some and so feeble in others—all of which are potent factors for rational prognosis. The influence of age is always important. Experience teaches how variable this is in different diseases. Diseases which are well borne by the young are often promptly fatal in the adult and in the aged. Thus diabetes is uniformly fatal during early life, often without serious consequences after the thirtieth year; pneumonia and typhoid fever on the other hand show a reversal of this prognosis; endocarditis following or associated with rheumatism in the young is always ominous ; in the adult it is less serious ; arteriosclerosis is among the conditions which are fatal during early life; the aged may live on with advanced arterial change with but few or no symptoms. An element which often influences prognosis unfavorably is the toler- ance of organs to pathologic change during long periods, without revolt. Early diagnosis improves the prognosis of most diseases. The tolerance of the stomach, intestines and other organs during long periods to invading cancer or other organic diseases without subjective manifestations brings the victim to the physician long after the initial period of the disease. The gradual unobserved advance of arteriosclerosis with kidney invasion is another example of insidiously increasing and un- recognized, but serious, disease. The localization of lesions is another factor which influences prognosis materially. The same general pathologic change so localized as to allow continuance of function practically unchanged, offers a more favorable prognosis than does a similar deposit so localized as to interfere at once with the necessary productive power of the organ. The influence of occupation in inviting disease and in fighting it is among the important questions to be considered in connection with prog- nostics. The increase of cardiovascular lesions dependent upon changed social and business conditions, the alarming arterial breakdown in men and women in the professions, especially the medical, the increase of cancerous diseases with advancing civilization, are among the problems which demand GENERAL CONSIDERATIONS 7 serious thought and attention in the attitude of the clinician to the indi- vidual and to the public. The influences of “constitution” and the “diatheses” on prognosis, par- ticularly during early life, are paramount. The inherent endogenous fac- tors which so change the blood plasma of children burdened by diathesis remain unexplained; they exist and handicap the child in the race of life. The knowledge of the presence of such condition makes it possible for the parent, aided by the attendant, to supply the resistance which in many instances proves sufficient to bridge the child over critical periods. The resistance which the different races offer to disease is among the interesting studies connected with prognosis, as well as the immunity which certain sections enjoy. Thus there is a decided variation in the vulner- ability between the light and dark complexioned races. Dyce Duckworth says: “The vital resistance and invulnerability of the Hebrew race is, to my mind, very noteworthy. So much so is this the case, that I am wont to frame a better prognosis generally for Jewish patients under all circum- stances.” In spite of this fact diabetes mellitus is most prevalent among the Jewish race. The negro invites tubercidosis and smallpox, and in him, both diseases are surprisingly fatal. The influence of habits, alcohol and intemperance, early training, exer- cise, exposure, environment, social status and the innumerable factors which arise in individual cases under the many conditions of life, each demands special consideration and proves the complex nature of prognosis. The varying character of epidemics, malignant during one outbreak, benign in another; the milder character of the cases toward the end of epi- demics, the seasonal influences, the variation in the virulence of the sepa- rate strains of infecting organisms, the immunity to infection against cer- tain disease-producing germs which often exists in the individual, the dif- ferences in disease to leave permanent immunity after a single infection and the predisposition to repeated infections with a like offender, often remain without satisfactory explanation, but all have a direct bearing on prognosis. There are facts which influence the acute infections, with which it is always safest to remember the admonition of Hippocrates: “In acute disease it is not safe to prognosticate either death or recovery.” It is equally important for the conscientious clinician to consider the fate of the descendants of his patients as well as their antecedents (family history). The application in practice of the Laws of Heredity demon- strated by the teachings of Mendel and his followers will prevent untold misery to many, during many generations. The improving of the “racial qualities” as advocated by the modern science of Eugenics cannot be ac- complished without the cooperation of the clinician. The questions connected with prognosis include the after effects of dis- 8 THE PROGNOSIS OE INTERNAL DISEASE ease as well as the relations of the infected individual to his surroundings. The prognostics of the infections teach the urgent need of long surveillance of the individual patient and the recognition of the dangers to vital organs after acute disease. This is particularly true of rheumatism, scarlet fever, pneumonia, typhoid fever, influenza and the exanthemata. The infected individual relieved of his acute symptoms may still he dangerous as a “carrier ’ and often becomes the starting point of far- reaching disease. The milder infections are as dangerous to their surroundings as are the more malignant and should he so considered by the proper authorities. The influence of neurophathic tendencies and the traumatic neuroses on prognosis is not to he lightly regarded. What Sir James Paget so happily named “the Mimicry of Disease” includes a chapter in medicine (Neuromimesis), which for its full interpretation and prognostic signifi- cance requires enormous knowledge, tact, and a judicial mind. The underlying anomalies leading to the complex of Neurasthenia may be said to include the same requirements for reliable prognosis and its rational treatment as the bJeuromimeses. Phagocytosis and extra cellular digestive processes are elements of enormous value in prognosis. The cure of bacterial disease results from the destruction of the micro-organism in the organ invaded and in the blood, by the aid of phagocytosis and the activity of extra cellular diges- tion. Iloekten has demonstrated in pneumonia—and this is probably true of other infectious disease—the general defensive reactions of leukocytes and the production of antibodies “of which the opsonins are the best known.” With inadequate destruction of pathogenic bacteria in indi- vidual disease and their proliferation, with the absence of antibodies from the blood the prognosis is bad; there is no army to meet the invadingf forces. The influence of acute infections on existing chronic diseases is often overlooked, faultily interpreted or not considered at all in framing the prognosis. The favorable influence of acute infection on the course of chronic disease at times has been fully appreciated, and the literature of the subject contains a number of striking examples taken from the experiences of acute clinical observers. In occasional cases chronic proc- esses of long duration have been so favorably influenced as to disappear entirely. In some the disease is held in abeyance only during a limited period, while in other cases the clinical picture of the disease may be materially changed by the added infection. Gerhardt reports: I. Trigeminal neuralgia relieved during acute pneumonia. II. Tuberculous ascites has after profuse diuresis been relieved during croupous pneumonia. GENERAL CONSIDERATIONS 9 III. Chronic arthritis—so-called rheumatism—has been without symp- toms during acute tonsillitis. IV. Acute psychosis is often controlled during erysipelas. V. Measles has relieved the pressure symptoms of brain tumor. VI. Chronic malignant tumors, facial carcinomata (epitheliomata) have often shown marked improvement, even cure, after erysipelatous infection. Kopff has seen subacute arthritis promptly cured spontaneously by erysipelatous complication. Measles has cured eczema capitis, chronic pemphigus, chorea, epilepsy and urinary incontinence. One infection grafted on another is likely to influence the primary infection. Splenic fever is prevented experimentally by inoculation with the erysipelatous streptococcus, prodigiosis, staphylococci or the Fried- lander germ. The influence of pneumothorax on the chronic tuberculous lung disease is thoroughly recognized. 1STaunyn has observed the favorable influence on sugar loss, without increase of hyperglycemia with the intercurrent infections of diabetics. There are cases of pernicious anemia which with tuberculous infec- tion show an improved blood picture (Diabella). The influence of tuberculous disease on the leukemias, also other infections, is often striking and favorable (See Leukemia for Eisner and Groat, also Dock’s references). Collective investigation of disease has resulted in the accumulation of data which strengthen prognosis and make it more certain than ever before. Among the diseases thus studied are tuberculosis, typhoid fever, the results of inoculation against the latter and against smallpox and diphtheria. The collective data which prove the prognostic value of the recognition of the specific nature of many brain tumors and the dependence of many liver enlargements and diseases on syphilis, and their disappear- ance under specific treatment are noteworthy. The subject of Cretinism and its prognosis has been enormously advanced by the collective investiga- tion made in England. A basis for classification was given and the in- fluence of the organic extracts—the introduction of which is easily the most marvelous advance made in medicine during the past century. The prognostic significance of the general symptoms (pulse, respiration, fever, et cetera) will be considered with the separate diseases. Tact and humanity combined, with all that is complete and highest in our art, a full knowledge of all that makes the cause and recognition of disease possible, scientific methods of treatment with reasoning ability sharpened by well digested experience and a delicate poise, are among the requirements necessary for prognosis. The question often arises in the course of practice whether it is wise 10 THE PROGNOSIS OF INTERNAL DISEASE to give an unfavorable prognosis in the individual case. The tactful 'phy- sician will rarely do harm to his patient by leading him to an appreciation of his condition without robbing him entirely of the hope to which he is entitled. The element of Hope in prognosis ought never to be disre- garded. It means much to be aided by a suggestion which stimulates hope. In cases of positively fatal diseases this will occasionally prolong life; if it does not do this, it certainly adds materially to the comfort of the individual and makes pain and mental pang more bearable. The power which the experienced physician holds over the patient for good or ill, by giving thoroughly considered and honest prognosis, is enormous. Much depends upon the method and tact of the attendant. Patients with acute infectious diseases rarely inquire themselves as to the outcome; those afflicted with sub-acute or chronic ailments unless they are deluded and fail to appreciate the seriousness of their maladies are eager for an honest prognosis. I have always contended that either the patient, some interested member of his family or close friend is en- titled to such information concerning the course of the disease as the physician can give with reasonable certainty. Distortion and misunder- standing cannot always be prevented. Where prognosis is impossible in the presence of a large element of uncertainty, the ignorant as well as the intelligent will respect the physician more for having candidly and without equivocation given expression to an opinion which proves his limitations than to a prognosis which finally proved to be incorrect. Patients when properly informed are led to a thorough appreciation of the gravity of their condition, but also understand that the physician is not infallible and that in the may come to the rescue. Further, the tactful physician, with patilfc even of ordinary intelligence, can so frame his prognosis without injurifgfcs to lead to the peace of mind which follows attention to the requiremeh®pf religion and to material affairs. In my experience I have invariab1|f|$imong our Catholic patients in hospital and in private practice given UlSkple time for the administration of the rites of the church in all cases where life seemed threatened by disease, usually with comfort resulting, without unfavorable influence on the course of the disease; in many cases the fight has been renewed and won. Cruel and heartless prognoses which rob the patient of all hope are never justified; one can be truthful without being barbarous. Thoughtless and unqualified prognoses have often led to sudden death and suicide. The blunt and inconsiderate prognosis of ultimate blindness in a case of locomotor ataxia in one of our patients made bv a busy, thoughtless ophthalmologist after a single examination of the background of the eye, without a knowledge of the previous history of the case of long continued eye symptoms, was followed by the suicide of the patient within the following twenty-four hours. GENERAL CONSIDERATIONS 11 The physician in many cases needs to he guarded lest he betray his feelings during the examination of the patient before he has thoroughly assimilated the facts in the case sufficient to lead to a diagnosis. Gardner says “Beware the unguarded word! Beware the unguarded hesitation! Beware even the unconscious sigh.” The setting of a time limit in framing prognosis is indiscreet, unsafe, unscientific. The physician may guess right and thus strengthen himself in the minds of the ignorant, but to the thinking layman and to the scientific, such a forecast is without value and weakens faith in the profession. Optimism in prognosis whenever honestly possible is justified. “It is 1 ot only the privilege of the physician but his bounden duty” to continue hopeful, for it may turn the scale in favor of the patient and start him toward recovery. Unwarranted optimism, however well intended, may lead to embarrassment and should not be encouraged. Honest suggestion with prognosis is an asset which belongs to the physician’s armamentarium. Though we may not always be justified in giving hope of complete cure, partial relief in many cases may be pre- dicted. We are often certain that the underlying pathologic condition can never be removed, but life may be prolonged and usefulness con- tinued. Percival’s advice in this connection is wholesome. “A physician should not be forward to make gloomy prognostications, because they savor of empiricism, by magnifying the importance of his service in the treatment or cure of disease.” . . . He should “give to the friends of the patient timely warning of danger, wffien it really occurs and even to the patient himself, if absolutely necessary.” Hot infrequently we are for a time, unless on guard, misled to change an original diagnosis and discredit prognosis. This is often true in cases of pernicious anemia, when for a time the disease remains stationary or improvement continues during long periods; in cases of ulcer of the stomach and duodenum, when symptoms disappear, but finally recur; in leukemia, in which modern methods of treatment lead to surprising but temporary reduction of lymphocytosis; in cases of cancer, where during long periods of latency the clinical features are entirely changed. In early life, we know the baneful influence of tuberculous glands; long periods of health may follow their neglect but in the end the original prognosis must stand. So, too, we are justified in calling attention to the grave import of the neglect of treatment of many diseases, in spite of few or annoying sub- jective or objective symtoms. The early diagnosis correctly made must always remain the foundation of authentic prognosis. The physician as his experience grows reaches conclusions wffiich mod- ify prognosis from his general survey of the patient, exclusive often of 12 THE PROGNOSIS OF INTERNAL DISEASE physical signs and subjective complaints. The physiognomy, the facies of the patient, the expression, the brilliancy or dullness of the eye, the way in which the patient lies or handles himself in the midst of serious disease, more particularly the infections; it is in short the picture which allows of no description, which cannot be defined, which impresses the clinician and materially influences the forecast. Dyce Duckworth has well said: “The organs may be found in detail free from structural disease, but there may be appearances and features indicative of progressive failure not yet registrable by the stethoscope or the test tube, of which the significance is of the last importance, and these may escape recognition and appraise- ment. ... A little more attention to the individual, his aspect, his gait, and his manner, would sometimes be well repaid in a sounder appreciation of his life value. ... I am constantly training students to begin by look- ing at their patients.” We often fail to take the time “for a meditative survey” of facts in order “adequately to apprehend the general laws which underly and govern them.” (Duckworth.) All of these facts prove that the art of prognosis can never be acquired from boohs. The clinician will rarely fail if he has the ability to read disease, if he correctly appreciates that added to his scientific knowledge, gained after painstaking examination and investigation, divorced from the test tube and the microscope, there is much which the ready eye sees which must influence him in treatment and in prognosis. Sir Jonathan Hutchinson was profoundly impressed by the lectures and clinical teach- ings of Laycock, afterwards Professor of Medicine in Edinburgh, for he taught the “value of the general appearance of physiognomy of the patient as an indication of his physical condition.” “An entirely modern idea—but one wdiich should imbue our minds nowadays—is that of defining in each particular case the mutual relation- ship between those three fundamental elements of medical judgment; to know, to foresee, to act.” (Chauffard.) “As observation becomes more accurate, as the number of observed cases increases, and as classes are better and better distinguished, the nearer will the physician be able to approach an accurate prognosis, though the time when any sufficient rule can be applied to individual cases must long be out of our sight and the application of any approximate rules must long be subordinate to the instinctive tact of the educated physician him- self, who alone can apprehend the sum of the peculiarities which must modify their application to individual instances” (Allbutt). With this statement before us, mindful of the many perplexing prob- lems included in Medical Prognostics, I hesitated to present any mate- rial to the profession until I had a long and broad experience in both private and hospital practice. I have sought in the consideration of the separate diseases to consider the cause and nature of the pathologic processes in connection with symp- GENERAL CONSIDERATIONS 13 toms and signs and to add to these my knowledge of the outcome of the combinations in the series of cases which served to supply the material. As I said in the preface, my desire is to bring comfort to the physi- cian, and through him benefit to the patient; this I expect to do hv stimulating the study of the forecast of disease through pathologic knowl- edge, diagnosis—as accurate as it can he made in the present state of our knowledge—with tact and humanity. “He who remains silent will not easily err. He will never shoot at a target, will therefore never miss it, but he will never he a thorough marks- man” (Gerhardt). We will often be disappointed and uncertain, “but since the science of prognosis is one of the loftiest summits of medicine” (Chauffard) we are never to slacken our pace. To make the supreme effort is our duty than which there is no greater stimulus to the active physician. References Adams (Francis). Preliminary discourse. In: Works of Hippocrates, 15. Allbutt.

Section I Specific Infectious Diseases A« Protozoan Infections I. Syphilis Lues Syphilis is a specific disease due to the Treponema pallidum of Schau- dinn (1905), which invades the blood and all tissues of the body from the primary and local lesion—the latter characterized by ulceration and in- flammation at the seat of inoculation—with prompt lymphatic invasion, probably a rapid, possibly a single excursion of the Treponema through the blood-stream to the various organs of the body, in which, after longer or shorter periods local changes of a productive and destructive nature may follow, depending on many factors, the most important of which is the early and intensive treatment of the disease. Wassermann Reaction.—Syphilis is inoculable to the ape and offers a positive Wassermann reaction which includes the indirect recognition of a specific antibody by the fixation of complement test. In the carrying out of the test through its two stages in the tubes in which complement has been absorbed, hemolysis is absent, therefore the test is “positive”; in the tube in which there is hemolysis the complement has not been absorbed and therefore the test gives a “negative” result. The Wassermann reaction is so exceptionally present in nomsyphilitic diseases that its presence in suspected syphilis justifies a positive conclu- sion. The few diseases in which the Wassermann reaction is present offer such positive symptoms as to make differentiation easy. Included among these are leprosy, framhesia, scarlet fever, rarely; occasionally cancer, tuberculosis and pregnancy complicated with acute yellow atrophy of the liver (Scholtz). We consider the prognosis of syphilis based upon the following classi- fication : 15 16 SPECIFIC INFECTIOUS DISEASES 1. Acquired Syphilis. (a) Early manifestations. (i) Primary and secondary stages. (b) Late manifestations. (i) Tertiary stage (including visceral syphilis. (ii) Late tertiary lesions — so-called metasyphilitic lesions. 2. Congenital Syphilis. (i) Intra-uterine. (ii) Post embryonic. Acquired Syphilis With the introduction into medicine by Ehrlich of chemotherapeusis including salvarsan, neosalvarsan and its modifications, the prognosis of all forms of syphilis in all of its stages has been enormously influenced, though we must confess that long years of observation are needed before positive conclusions can be reached which justify a forecast of the syphi- litic’s future who to-day subjects himself to the modern and supposedly rational treatment of the disease. By modern diagnostic methods, i. e., the Wassermann reaction and the examination of the spinal fluid, we are able to reach positive conclusions with regard to the activity of the infection in all of its stages. Primary Stage During the primary stage of the disease the patient as well as the attendant should recognize in syphilis a serious infection, which, if a favorable forecast is to be given must include not the treatment of the palpable and visible symptoms alone, but the constitutional invasion by intensive methods. The prognosis of untreated cases of syphilis is unfa- vorable for the subject infected, his offspring, and for the nation. There is no spontaneous cure of syphilis; no subject is safe to his surroundings who has remained untreated. Symptoms may disappear during periods which vary in length, but in all there are recurrences which include de- tected or undetected lesions (mucous patches especially) from which in- fection may spread to the innocent. Bramwell has called attention to the fact, and his experience is corroborated by that of others, that those syphilitics are most likely to develop the serious late manifestations of the disease who are insufficiently treated during the primary and secondary stages; who, after the disappearance of visible lesions neglect themselves. The 'prognosis, therefore, of constitutional syphilis is enormously influr enced by the rational, scientific, and intensive treatment of the early mani- festations of the disease. Not all subjects react alike to syphilitic infection. In some, we find a PROTOZOAN INFECTIONS 17 tendency toward malignancy in the obstinacy of the initial lesion and in its early tendency to deep destructive changes with marked constitutional dis- turbances; and in some, the early invasion of the nervous system. Others, present features which at once brand the infection, so far as evident changes and reactions are concerned, as benign during the early days of the disease. Such behavior should not mislead, for mild and evidently benign cases during the early stage may offer late manifestations and so- called metasyphilitic lesions out of all proportion to the benign nature of the early symptoms. Syphilitics who are reduced by previous disease, constitutional anom- alies, who are inherently weak and nonresistant, are likely to show the effect of such handicap during the early stages of the disease. The influence of syphilis on tuberculous disease is considered sepa- rately (See Tuberculosis). Alcoholics and the dissipated are prone to show ulcerative and de- structive changes, with marked constitutional disturbance during the pri- mary stage of the disease. The phagedenic tendencies of syphilitic tissue in alcoholics is characteristic. The aged and overworked who contract syphilis show great tendency to destructive and constitutional symptoms, including wasting of tissues, anemia and asthenia. Blood Changes During the Early Stages.—Marked changes in the red corpuscles during the early stages are exceptional. There may be a slight reduction of erythrocytes, but this is not significant. In the exceptional case in which there is a material reduction of ery- throcytes—late during the primary and in the secondary stages—the infec- tion is severe, or there is lowered vitality of the patient, previous disease, or some one of the diatheses. The hemoglobin during the secondary stage in the average case which progresses favorably does not fall below 70 per cent, while as Haegeli has shown, the red blood-corpuscle reduction is insignficant. When during the. secondary stage hemoglobin falls to 30 per cent or only slightly higher, the infection is severe and the prognosis should be guardedly given. Several authors have claimed that there is a lymphocitic increase during the acute stage; this we have not been able to confirm. It is safe to con- clude that the lymphocytes are markedly increased only when the patient shows marked improvement after the early stages and as FTaegeli reports, this should be regarded as a ‘“post-infectious lymphocytosis.” High leuko- cytic counts are rare (24,000). Our average leukocytic count of the sec- ondary stage is between 9,000 and 11,000. With leukocytosis, if present, the large mononuclears are increased. Following the injection of salvar- san, with the improvement of symptoms, a slight increase of neutrophils is found without the disappearance of eosinophils. 18 SPECIFIC INFECTIOUS DISEASES Constitutional Symptoms.—During the primary stage there are rarely threatening or even serious constitutional symptoms from which the subse- quent course of the disease can be foretold. The fever of invasion may be associated with constitutional distur- bances including malaise, rapid pulse, depression and myalgia; the fever may be markedly intermittent, remittent or during a limited period may remain continuous, thus clouding the diagnosis. With all syphilitic febrile anomalies, the prognosis is good and conval- escence rapid. Wassermann Reaction During the Primary Stage.—Positive Wasser- mann reactions are not present during the early days of the initial lesion. In 70 per cent of cases, the reaction is positive between the fourth and seventh week. The time of constitutional invasion corresponds with the appearance of the positive Wassermann reaction. Bayly says: “Primary cases in which the lesion has been present for less than a fortnight almost invariably give a negative reaction, while 75 per cent of positive reactions are obtained if the primary sore has been present for over a month.” Secondary Stage The secondary stage is reached in from four weeks to three months after the appearance of the initial lesion. While the lesions of the secondary stage may be numerous, there are rarely serious complications during this stage. Positive Wassermann reaction is present in practically all cases during the secondary stage of the disease, showing itself between the fourth and seventh week after the appearance of the initial lesion, as already men- tioned (95 to 98 per cent). The Wassermann reaction is also positive in 90 to 95 per cent of cases during the tertiary stage (Scholtz). Skin Lesions During Secondary Stage.—The roseola eruption may be so slight as to escape detection; with modern treatment it is usually absent. It is not persistent, and fades entirely in from four to fourteen days. Papular and pustular eruptions are more persistent than is the roseola syphilitica. Early pustulation in our experience has been evidence of the most re- bellious type of the disease. Squamous syphilids, early, are also evidences of resistance to the treatment, and unless they yield after systematic and intensive treatment, may be considered expressive of the more malignant types of syphilis. But few cases escape mucous patches: in all cases they are likely to recur. Their presence is always positive evidence of active syphilis and we place great importance upon this lesion in framing the prognosis which includes indication for the future treatment, and in deciding the many PROTOZOAN INFECTIONS 19 questions associated with modern eugenics. We insist that the 'presence of the mucous patch, wherever found, should lead to further observation and intensive treatment and always argues against the advisability of marriage. The prognosis of syphilis during this and subsequent stages is un- favorably influenced by the neglect of treatment: to wait until secondary symptoms appear is unwarranted, and influences the case unfavorably. The negative Wassermann reaction during the early stages of syphilis does not justify the conclusion that the syphilitic is cured. The negative phase may be followed by a positive reaction and a return of symptoms. With lesions suspicious of the secondary stage, mild or incomplete reac- tions should not be accepted as conclusive evidence, and should lead to further tests. The fever of the secondary stage behaves much like that of the primary; there may be no fever during the latter stage, or as usually happens, the fever begins with the end of the primary and the beginning of the sec- ondary stage. In all of these the prognosis remains unaffected. The ma- jority of cases remain afebrile throughout the early stages, or if fever is present, patients fail to recognize it. Accompanying Manifestations.—The severity and localization of the lesions of the secondary stage depend upon the seat and extent of the de- posits of the Treponema. The excursion of the Treponema pallidum through the blood is immediately followed by its deposit in the various organs of the body. The skin receives the larger number of spirochetes; hence the multiplicity and preponderance of lesions in it. The treponemata are held in the contracted capillaries of the skin, where they proliferate and cause changes. Alopecia.—Pronounced alopecia is evident in many cases; few that are radically treated have more than insignificant loss of hair. It is relieved quicker than is leukoderma ; it rarely causes permanent bald spots (alopecia areata). Alopecia is, in most cases, favorably influenced by radi- cal treatment. The other skin lesions of the secondary stage including the small papu- lar syphilid, leukoderma, serpiginous and psoriatic syphilids, and condy- lomata are all amenable to treatment. Coxdylomata.—Condylomata are a source of infection and should be so regarded by the clinician. Nephritis.—Nephritis sometimes develops during the secondary stage. The prognosis will be considered with the visceral lesions of the tertiary stage of the disease. Arteritis.—Arteritis may be an early complication; it may invade the cerebral, renal, or coronary arteries or may be general: the prognosis is not bad if detected early. Early Myocarditis.—Early myocarditis may prove threatening; its 20 SPECIFIC INFECTIOUS DISEASES rational treatment usually leads to recovery. It will be considered under Heart Complications with visceral syphilis. Joint Invasion of Secondary Stage.—The joint invasion of the secondary stage is not serious. There is improvement under treatment after a few days or weeks of ill-defined pain, which may resemble acute or subacute arthritis, occasionally gout—without recurrence in most cases. The Eye.—Inflammatory conditions of the eye are not uncommon; the most painful and threatening among these is iritis. This usually yields to treatment after several weeks; there is but small remnant of disease left. In some cases adhesions cause permanent damage, though sight is preserved and often somewhat reduced. The Ear.—Ear changes are rare, when present they yield slowly to treatment. Lues Maligna.—The evidences of malignant lues during the early stages include ulceration of the skin and mucous membranes which may be disseminated. Papular lesions may promptly ulcerate; ecthymatous lesions are also characteristic with the development of rupia syphilitica. These lesions of malignant lues during the secondary stage do not de- velop, as do the ulcerations of the tertiary stage from gummatous tissue, but from the small and rapidly ulcerating papule or pustule. The fate of these, in the malignant cases of secondary syphilis, is surprising rapidity of ulceration with the upbuilding of crusts and the characteristic lesions of ulceration, the edge of which is in direct contact with the normal skin. “Galloping syphilis,” “malignant” and “florid,” always gives a posh live Wassermann. Galloping syphilis is associated with marked constitu- tional'disturbances, high fever, rapid pulse, and early arterial degeneration of an amyloid character. The prognosis of these cases in spite of active treatment is often bad. Many of these malignant cases bear medication badly; and when they do improve relapses are frequent and threatening. Evidently the subjects of malignant lues, for some reason, have less resistance to syphilitic infection than is possessed by average normal indi- viduals (Scholtz). Finger believes that in the ancestors of these subjects syphilitic infection was absent during many generations and because of the lack of the average immunity caused by such infection, the malignancy cor- responds with that of the disease during the early years of its existence in Europe. The absence of marked enlargement of the lymphatic glands dur- ing the early days of syphilitic infection in malignant cases, and the con- sequent failure to get the protecting influence of these, is advanced by others as a cause for malignancy. In some of the malignant and galloping cases, cachexia, diatheses, pre- vious disease and dissipation, should be considered as provocative. Malig- nant lues, complicated with visceral lesions early, offers a very dubious prognosis. PROTOZOAN INFECTIONS 21 Period of Latency.—This period has been described by Browning and Mackenzie as “a state of equilibrium between the host and the parasite” (Bayly), while Ehrlich gave it the name of “non-sterilizing immunity.” In the majority of cases, following the symptoms of the secondary stage as shown by skin lesions, mucous patches, and the positive Wassermann reac- tions, all symptoms may disappear and to all appearances the subject is cured ; in 50 per cent the Wassermann reaction becomes negative. For safe prognosis, these cases should be considered to be in a latent stage, and a positive forecast should not he offered. Relapse from the latent stage is the rule in from three to nine months with either mucous patches—usually buccal or tonsillar—skin lesions, and the return to the positive.phase (Was- sermann) of all. The foregoing facts are of enormous prognostic significance and their correct interpretation means much to the patient and his surroundings. The great value of the Wassermann reaction for the indications which it offers for treatment and 'prognosis must he recognized during this stage; it discloses “these hidden or latent cases, and in this way to cure them and to protect against the much dreaded parasypliilitic complications” (Neis- ser): The lighting of the disease to activity, as is shown by the return of the positive Wassermann reaction, where before the blood gave a negative response and an increase in the depth of color of existing skin lesions, is known as the “Jarisch-IIerxheimer reaction The prognosis of these cases is enormously improved for the recrudes- cence of the infection, and further lesions are prevented by appropriate treatment and the following of the indications offered by repeated Was- sermann reactions. In some, the latent phase is promptly changed to a positive reaction by the treatment. We quote from Bayly: “A single negative reaction obtained with the serum of a patient undergoing treat- ment by mercury or salvarsan means little but that the patient is reacting to such treatment. A series of negative results taken at intervals of three to six months after all treatment has been given up is necessary before the patient can be regarded as cured, and even then, until twenty years have passed, we cannot be absolutely certain that the disease is completely and permanently obliterated and that no late manifestations will ever occur. It is most important to remember that about 10 per cent of untreated cases of syphilis fail to give a positive reaction at the first examination, and that therefore a negative reaction only gives a 90 per cent probability of free- dom from infection.” During the secondary stage of the disease, the influence of the treat- ment on the Wassermann reaction offers decided indications for prognosis and the modification of the further treatment. If with treatment the reac- tion continues strongly positive, the medication is insufficient and the dis- ease uncontrolled. If the Wassermann reaction (a smaller complement is fixed) shows decided change, feeble reaction or the negative phase, the 22 SPECIFIC INFECTIOUS DISEASES treatment is efficacious—the disease is under control and the prognosis is correspondingly better. Length of Secondary Stage.—The length of the secondary stage is variable. It may cover a long period of years, rarely longer than 4 to 5 years, though mucous patches and small and large papular syphilids are found long years after the clinician had considered the stage passed. Smokers may show mucous patches so long as twenty and thirty years after infection. It is impossible in the individual case to be positive that the secondary stage is ended, until symptoms of the tertiary stage develop. This is an important fact. The secondary stage continues to be dangerous because during its persistence, the disease continues communicable. The Cerebrospinal Fluid.—The lumbar fluid gives valuable data for prognosis in the advanced stages of syphilis and in the secondary stage. Dreyfus, who has now made over 1,500 lumbar punctures, finds a positive Wassermann reaction during the early stages of syphilis in over 80 per cent of all syphilitics. This proves the early dissemination of the Treponema to the central nervous system, and that this may exist without subjective symptoms. It is assumed that a persistence of the Wassermann reaction during and following the secondary stage—a condition which is usually due to faulty treatment or malignancy of the infection—makes the prog- nosis unfavorable; for such subjects will be likely to develop serious ner- vous lesions: they are candidates for late tertiary disease (paresis, tabes, etc.) Under improving conditions during the early stages—usually due to treatment and rational living—the previously increased intralumbar pres- sure is lowered, the Wassermann reaction becomes negative in the blood and in the lumbar fluid. The influence of treatment on prognosis during the secondary stage can be best interpreted by the results of the Wassermann test of the blood and the lumbar fluid. Positive Wassermann reaction of the lumbar fluid in the secondary as well as in all stages of syphilis must be interpreted as posi- tive evidence of specific infection of the nervous system, and until a nega- tive phase is reached the disease cannot be considered to be under control; hence the enormous influence on prognosis of these results. We will refer to the importance of the examination of the cerebrospinal fluid in connec- tion with late tertiary disease. The blood may give positive Wassermann reaction, but unless the nervous system is involved, the spinal fluid will continue to give negative results. Besides ■ increased pressure there is marked increase of albumin during the secondary stage; both disappear under proper treatment. During this stage there is marked lymphocytosis of the fluid, and with severe nervous symptoms this is decided with great increase of the albumin content. Lymphocytosis of the fluid attends over 50 per cent of all secondary syphilis. Plant- claims that the cerebrospinal fluid shows leukocytosis in one-third of all secondary syphilis, one-third are on the border line, and the remnant shows no cellular increase.” PROTOZOAN INFECTIONS 23 Tertiary Stage The tertiary stage of syphilis begins the period of late manifestations, during which there is no danger of infection to others, in which there may be years of latency, and in which visceral lesions may develop in vital organs. Tertiary syphilis, when it attacks the skin, leaves the remnant of the lesion which caused tissue breakdown in a characteristic cicatrix—in contradistinction to the secondary lesion. The cutaneous lesions are not so extensive as during the earlier stages, but more destructive. They are often asymmetrical, and during this stage, the internal organs may be invaded. The tertiary stage is characterized by the deposition of gummata, true granulation tumors. The tendency of all gummata wherever found is to necrosis and cica- trization. Gummata vary from microscopic-sized to large orange-sized tumors—occasionally even larger. The fate of the gumma of the skin is necrosis with ulceration, unless promptly influenced by treatment whereby these changes may be modified. When thus influenced, resorption takes place with resulting stellate cica- trization. In the liver, healed gummata often leave large and deep cica- trices with sufficient remnant of normal tissue to lead to unchanged func- tion of the organ. We will refer to the behavior of multiple gummatous deposit and its prognostic importance in connection with a consideration of the separate organs involved. Cutaneous Lesions of Tertiary Stage.—The cutaneous lesions of the tertiary stage include: (a) Papular syphilids (b) Gummatous syphilids. (a) Papular Syphilids—Papular syphilids include tubercular, tu- berculo-serpiginous syphilids, ulcerative serpiginous syphilids, rupia syphi- litica and psoriasis syphilitica. In all of these, ulceration and cicatriza- tion of the invaded tissue follow as a rule. (b) Gummatous Syphilids.—It is difficult to draw a sharp line be- tween papular syphilids and skin gummata; both rest on the same patho- logic foundation. This is particularly true of the serpiginous syphilids which ulcerate (serpigino-ulcerative syphilids). Both forms of tertiary cutaneous syphilids offer a good prognosis in cases which are not malignant and which are subjected to rational treatment. Neglected gummata of the scalp which invade the periosteum may lead to deep tissue loss and ulcerative destruction of bone. Gummata of the nose, which are internal—invading bone and mucous membrane—lead to destruction of the septum and other changes. The result of bone destruction leads to the characteristic deformity known as “saddle nose.” It often happens that gummata invade the nasal periosteum without causing symptoms sufficient to bring the patient to the physician, until irreparable injury has resulted. The perforation in such cases is the first evidence of destruction. The septum is the seat of gummatous deposit 24 SPECIFIC INFECTIOUS DISEASES by predilection. The syphilids of the alee nasi and other parts of the nose are often destructive in malignant and untreated cases: early prompt treat- ment, local and constitutional, usually leads to satisfactory results with little damage remaining. Gummata of the tongue, soft palate, tonsils, and buccal mucosa tend toward prompt breakdown of tissue and perforation. Cicatrices often lead to adhesions and consequent distortion. The hard palate is often included in ulcerative destruction and is perforated. The Blood during Tertiary Stage.—There is but slight, if any, change in the red blood corpuscle count; there may be slight anemia in the average case. Severe anemias are always an expression of malignancy—depleting conditions due to complications and cachexia. Almost all severe anemias occur during the tertiary stage of the disease; they may be of the chlorotic type without leukocytosis. With chlorosis there may be leukocytosis or an approach to the picture of pernicious anemia. It is very rare that death follows these severe anemias. The larger number are found in over-wor- ried and weak women: many of these, work and live in unfavorable sur- roundings. Hemolysis following the administration of mercury may be a cause of grave anemia and is unfavorable; it shows intolerance of specific medica- tion. The presence of many large mononuclear lymphocytes has been re- ported by several reliable observers (14.1 per cent) (Hauck). The leuko- cytic count, in favorable and in the average cases, is between 9,000 and 13,000 (Sabrazes and Mathis). Cerebrospinal Fluid during the Tertiary Stage.—In severe cases of tertiary syphilis the albumin content is large. Leukocytosis is found in cases which have been neglected or insufficiently treated. Disappearance of leukocytosis, and decrease of albumin, with lowered pressure, are proofs of improvement; there are exceptions to this rule, for occasionally the change is insignificant. With involvement of the nervous system there is lymphocytosis. The cells are small mononuclear with a few larger kite-shaped lymphocytes; the nucleus is in the broadened protoplasm of the cell. The presence of leukocytosis in the withdrawn fluid is always proof of organic disease, in spite of the absence of subjective symptoms. Func- tional neuroses never show leukocytosis. Lymphocytosis is proportionate to the gravity and extent of the inflammatory changes—usually in the men- inges—and the prognosis can usually be favorably influenced by early rigorous treatment. Plaut, Bayly and others agree that a “negative cyto- logical examination, namely, the presence of less than six cells per c. mm., will exclude general paralysis, syphilitic meningitis and tabes.” Frequency of Tertiary Lesions.—The frequency of tertiary lesions is certainly decreasing under modern methods of treatment and the increased PROTOZOAN INFECTIONS 25 knowledge of the effects of syphilitic infection among the masses. It is unfair to reach conclusions from hospital material alone, for such cases are usually found among the neglected, insufficiently treated, and the in- temperate. Seholtz says that “the percentage may be placed between 15 and 20 ; more accurate statistics are not available, for the lesions of tertiary syphilis may not appear for twenty to thirty, yes, forty years after infec- tion—periods so long that it is impossible to follow the cases and determine their fate.” Tertiary lesions are invited by depressing influences, alcoholism, faulty nourishment, diathesis, tuberculosis and lympliatism. Tertiary lesions are often present without the patient’s knowledge of syphilitic infection: hid- den, unobserved and untreated primary lesions account for these in over 50 per cent of cases. But few, thoroughly treated during the initial and sec- ondary stages of syphilis, develop tertiary lesions. Early and apparently benign symptoms do not preclude later malignancy and deep tertiary lesions. Such cases are likely to be neglected; occasionally in spite of ra- tional treatment they lead to so-called metasyphilitic disease. Neissers statistics which follow, are of great value for our purposes: they show how rarely patients with tertiary symptoms are treated radically during the early stages of syphilis and how often patients with tertiary symptoms re- ceive no treatment at all.

Visceral Syphilis in Tertiary Stage The incidence of tertiary and metasyphilitic disease of the internal organs now considered late tertiary syphilis, has been proved by the newer 26 SPECIFIC INFECTIOUS DISEASES methods of diagnosis—the Wassermann reaction particularly—to be more frequent than has been heretofore suspected. When we include among these the many cardiovascular conditions, formerly unexplained, and the specific diseases of the nervous system now known to be of luetic origin, we add an enormous material, and increase the percentage accordingly. Visceral syphilis includes the diseases of the internal organs which develop during the tertiary stage of the infection. It must not be forgot- ten that occasionally vital organs are attacked during the secondary stage of the disease; these include the kidney, central nervous system, the osseous system, the vascular system and rarely the liver. The organs which are attacked during the tertiary stage include the arteries, veins, the heart, the liver, the kidney, the bones and joints, the rectum, the digestive tract, the spleen, the testicles, the bladder and genitalia, the respiratory organs, and the central and peripheral nervous system. Specific Diseases of the Cardiovascular System Arteritis.—The classic work of Heubner, in which he called attention to the importance of lesions of the smaller cerebral vessels, which are always characteristic of endarteritis, in which the intima is the seat of proliferative change—still serves as the basis of our knowledge of the subject. The disease does not limit its ravages to the intima, for in advanced specific arteritis all coats may be invaded. The student of medical literature is referred to Virchow’s comprehensive treatment of visceral syphilis, which is one of the most marvelous additions of the past century. It can bei easily understood how far-reaching the influence of specific arteritis may be, and how many organs may suffer at the same time. Such weakening as is caused by endarteritis specifica of the arterial walls may lead to miliary or large-sized aneurysmal dilatation, with the included secondary manifestations. (Aneurysm of the aorta and larger vessels are separately considered.) The changes wdiich follow in the cerebral vessels and their baneful results, with prognosis, are considered with Cerebral Syphilis. With practically all specific arteritis the Wassermann reaction is positive. Specific arteritis invading the coronaries gives rise to threaten- ing symptoms, including the complex of angina pectoris. It must be remembered that stenocardia is not always, even during early life, of specific origin. Heredity is an important factor in many; but in young subjects evidences of arteritis, including coronary invasion, should always lead to the strong suspicion of syphilis as a cause, to corroborative Was- sermann tests, and specific treatment. If the myocardium is not too far degenerated, and other vital organs are not invaded—kidney, brain, etc.— the prognosis is fairly good. PROTOZOAN INFECTIONS 27 No specific arteritis is so far advanced as not to justify specific treat- ment, for in extreme cases we are often unexpectedly successful. Results have often been encouraging in cases which suffered repeated anginoid attacks. Blood-pressure study of these cases needs to he correctly interpreted to give data of value. If the endarteritis has existed during a long period, has been extensive, has involved the renal and mesenteric vessels, there will probably be a high systolic pressure with a high pulse pressure, a tense and thickened radial pulse. These cases also have decided accentua- tion of the second aortic sound and often an aortic systolic murmur. The aorta is included in the process and shows the characteristic changes of specific aortitis. The result of blood pressure study alone in such at case is valueless, this must be added to all which the case presents before prog- nosis is justified. Such cases as we have above mentioned are of serious character, they demand a guarded prognosis and before it is positively given, the effect of treatment should be studied. With some of these cases, the blood- pressure may be normal or reduced; such reduction is then evidence of myocardial weakness, and the prognosis is thereby unfavorably influenced. Specific obliterating endarteritis may cause gangrene of an extremity or less striking trophic changes. We have found intermittent claudica- tion, erythromelalgia, and symmetrical gangrene of the finger tips (Ray- naud’s disease), in which the underlying arteritis proved to be specific and in which rigorous treatment led to the recovery of some, and the material improvement of others. Specific amyloid degeneration of small and large vessels is always' serious; it is usually associated with similar degenerative processes in other vital organs, and is not often relieved by treatment. When the kid- ney is involved in a similar process and there is anemia gravis, but little hope can be given. For the purposes of the prognostician, it is necessary to assume that all unexplained arteritides in young subjects should be suspected to be of syphilitic origin, and demand the refinements of diagnosis and therapeu- tic tests before final conclusions are reached. Naturally the prognosis of arteritis specifiea depends largely upon the importance of the organs directly involved, and the influence of the changed relations. Aortitis Syphilitica.—Specific aortitis may lead to aneurysm of the aorta; it may be associated with non-specific arteriosclerosis of the aorta, but its seat is characteristic in almost all cases during its early existence. Uncomplicated specific aortitis causes irregular thickening of the aortic wall (fibrous thickening), with patches of thinner tissue between these plaques. It invades the ascending aorta and the arch. There is a distinct line of demarkation which separates the changed aorta from the valve and tissues of the aorta directly above it. The prognosis is uncertain. 28 SPECIFIC INFECTIOUS DISEASES Physical signs of aortitis and subjective symptoms often disappear under treatment. There are according to Grassmann accidental or functional murmurs in 40 per cent of cases during the secondary stage of syphilis. In occa- sional cases during this stage, there may be threatening incompetence of the heart with low blood-pressure and dilatation of the right heart. Fever and anemia may be present. The prognosis is good in almost all of these cases. One of the dangers occurs from suddenly arising pulmonary edema. Heart Syphilis.—There is no tissue of the heart in which specific dis- ease may not cause organic change. We have mentioned coronary and aortic disease; the endocardium may degenerate, the aortic valves partic- ularly may be the seat of specific deposit and change, the myocardium may be uniformly infiltrated and degenerated—it may hold one or more gum- mata—the pericardium may be involved; in all of these the Wassermann reaction is likely to be positive. The Wassermann test has given us positive information concerning an enormous material which was formerly unexplainable. We refer to those heart lesions, the pathogenesis of which Xve did not understand—includ- ing especially the degenerative rather than the inflammatory processes—- usually found during middle life when arteriosclerosis and disorganizing changes are unexpected. The larger number of these lesions are aortic, endocardial, myocardial and coronary. The aortic lesions are in the ascendency. In over 50 per cent of these unexplained cases the Wasser- mann reaction is positive, and the prognosis is accordingly improved. Aortic valvular lesions are found with positive Wassermann reactions in over 55 per cent of our cases. There are unquestionably many specific lesions of the heart which never give rise to symptoms, which remain undetected, and are cured by the treatment of the constitutional infections, just as the large proportion of positive Wassermann tests of the cerebrospinal fluid and its cellular elements prove that changes in the nervous system may exist without sub- jective symptoms, which also disappear under similar conditions. We have elsewhere called attention to the evanescence of physical signs, the disappearance of murmurs with positive organic disease. Re- cent additions to our knowledge, prove these cases to be of specific origin, and materially improve their prognosis (Eisner). The prognosis of specific myocarditis depends on the length of its existence, the associated lesions, and the effect of specific treatment. Cer- tainly the prognosis of the degenerative diseases of the myocardium due to syphilis is much better than non-specific disease. Harlow Brooks says: “Nearly all cases of syphilis are well treated at least for so long as mucous membrane or skin lesions present themselves; just as long as these show, the patient is willing to submit himself to treatment and to observation. PROTOZOAN INFECTIONS 29 Hence, it is that at least for a time, many or most cases of cardiac involve- ment are correctly treated even though unrecognized.” Lesions of the heart of specific origin, including degenerative myo- carditis, valvular lesions, arteritis of the heart vessels, may become latent; they may “heal and resorb under proper medication.” There are unques- tionably many heart lesions during the early stages of syphilis which give rise to no symptoms—which unchecked would prove fatal—but which are stayed and cured by specific treatment. Cardiac lesions of late syphilis may often be threatening, the heart may be insufficient and yet under treat- ment there may be recovery or marked improvement. The prognosis can- not be given until the treatment has been sufficiently tested. Brooks says: “It is also true that a cheerful prognosis is not permissible until it has been determined just how much may be achieved by proper treatment. So frequently have I been deceived in both directions, that I now refuse prog- nosis until the case has been under treatment at least for a time—after which from the degree and character of the improvement or its failure, one may quite accurately prognose what may be expected with a further prosecution.” The Stokes-Adams phenomenon has in a few cases been found with specific degeneration of the intraventricular septum (Ilis fibers) ; gumma have been found in several cases post mortem. Such cases offer a serious forecast, though improvement or recovery may follow; rigorous treatment. All cases of infiltrating specific myocarditis must be considered se- rious, and justify only a tentative prognosis until the horizon is cleared by treatment, including rest. Mracek gives the specific heart lesions wffiich he found in 60 cases: Gummatous myocarditis 10 Fibrous myocarditis 9 Gummatous and fibrous myocarditis 8 Endocarditis 2 Coronary arteries alone 3 Pericardium alone 1 Myocardium and pericardium 15 Pericardium, myocardium and endocardium 1 Myocardium and coronary arteries 1 All parts of the heart 6 Cardiac ganglia 4 (For further information concerning the fuller pathologic data which influence prognosis, the reader is referred to the works of Virchow and Mracek, above cited; also Hirschfelder, Huchard, Isaac Adler, Aschoff, Gruber and Stadler.) Phlebitis syphilitica.—Changes in the veins may lead to phlebitis, phlegmasia alba dolens and erythematous nodes associated with fever* and exacerbation of constitutional symptoms. In all of these conditions the prognosis is favorable. 30 SPECIFIC INFECTIOUS DISEASES Syphilis of the Liver Specific diseases of the liver are found with: (a) acquired syphilis, (b) congenital syphilis. Specific lesions of the liver are the most frequent of the visceral diseases found in the abdomen. (a) Acquired Syphilis of the Liver.—Jaundice is not unusual dur- ing the secondary stage of acquired syphilis. The bile passages and liver parenchyma are invaded. The organ may be slightly enlarged. These cases run a benign course and recovery is the rule after a short period of treatment. Acute Atrophy of the Liver.—Atrophy of the liver occasionally arises during the secondary stage of syphilis, and with all of the symptoms of rapid degeneration, jaundice, sepsis and heart weakness; these patients die within from forty-eight hours to three or four days. Rolleston has reported twenty-eight cases of postsyphilitic acute atrophy of the liver. Gummata.—The liver invasion of the tertiary stage is usually gum- matous. There may he interstitial infiltration and connective tissue proliferation with marked contraction resembling the atrophic form of cirrhosis of the liver. These are not so-called parasyphilitic lesions, but are due to the proliferation of the treponema in situ. Specific diseases of the liver are usually associated with more or less fever of an atypical type; and multiple gummata may lead to the sus- picion of liver cancer and abscess. With nodules situated anteriorly, the masses are palpable. There is wasting and progressive weakness with the fever. There is also pain and the enlarged liver is tender. With dissemi- nated nodules there is usually ascites, more or less perihepatitis, and occasionally jaundice. Perihepatitis is an attendant of almost all liver gummata. With lues maligna (malignant syphilis) amyloid degeneration of the liver with enlarged and waxy spleen and kidney invasion is frequent. Characteristic anemia accompanies these conditions. The prognosis of uncomplicated gummata of the liver or specific hepa- titis and perihepatitis is usually good. It is surprising to find how promptly these cases improve under modern treatment. Cases that have been neglected, with complications, particularly in those whose resistance is below par, are serious. Malignant lues above mentioned, with the asso- ciated liver complications, is always ominous; usually death is thei result of widespread amyloid degeneration. (b) Congenital Syphilis of the Liver.—Syphilis of the liver may be an early or a late complication of congenital syphilis (lues hereditaria tarda). The early manifestations are those of far-reaching hepatitis: the Treponema pallidum can be found in the liver tissue. There is at the same time invasion of the spleen and kidney: occasionally the pancreas shows marked fibroid change. These changes may be found in the still- PROTOZOAN INFECTIONS 31 horn syphilitic child, or death may follow during the first week. Cases of congenital liver syphilis which develop early may occasionally, under prompt and rigorous treatment, recover; a grave prognosis should however always be given. With jaundice and ascites there is but little hope. Lues Hereditaria Tarda.—The tardy form of liver lues is always an interesting condition which usually develops sometime between the tenth and twentieth year in subjects who have all of the earmarks of the constitutional infection well developed in the skin, teeth, hones, eyes, and in faulty growth. Arterial changes with marked narrowing of the vessels are usually present. The physical signs referable to the liver are much the same as with the acquired forms of gummatous and interstitial hepatitis. Amyloid degeneration is usually widespread. The spleen is enlarged. Perihepa- titis is almost constant. The majority of these cases are neglected; after long periods of indefinite symptoms. Death is the rule with symptoms of toxemia, uremia, etc. Cirrhosis of the liver is not caused by syphilis, but there are cases in which syphilis of the liver may complicate and materially influence the course of the cirrhotic process. With congenital syphilis, changes which are differentiated from cirrhosis with great difficulty, are found. They offer a grave prognosis. The prognosis of all forms of liver enlargement or of liver lesions will, in a surprising number of cases where serious non-specific disease is sus- pected or even diagnosticated, be favorably influenced by specific treat- ment. This is a dictum of great importance. Syphilis of the Kidney During the secondary stage of the disease as already nephritis may develop. It usually appears with the roseola eruption. The features are those of acute tubal nephritis (parenchymatous), with dropsies and abundant albuminuria and casts. These cases are usually amenable to treatment, and recover. Neglected cases die of uremia with myocardial invasion as a rule. Occasionally subacute and chronic nephri- tis originates during the secondary stage. Tertiary syphilis may lead to gummatous deposit in the kidney, when there may be physical and subjective manifestations of renal tumor. Chronic interstitial nephritis may he associated with specific arteritis and specific heart changes (myocarditis). There are mixed forms of nephritis, also amyloid degeneration, with similar changes in other organs of the body. Interstitial nephritis and waxy or amyloid kidney are the most frequent kidney changes of tertiary syphilis and are never to be lightly regarded; they offer a serious prognosis. The gumma of the kidney im- proves and its size reduces with return to normal, after a sufficient period 32 SPECIFIC INFECTIOUS DISEASES of rigorous treatment. Scars are found in such kidneys—proving the possibility of cure. Syphilis of the Testicle and Epididymis Early swelling of the testicle and epididymis of specific origin are promptly influenced by treatment, and lead to full recovery without injury to the organs infiltrated. The late manifestations of syphilis usually limit themselves to the testicle; the epididymis escapes. The late processes may be either gummatous or there may be a diffuse interstitial infiltration of the organ, or both forms may be together (Scholtz). Scholtz calls attention to the fact that even with relatively early treat- ment the functions of the testicle may suffer; spermatozoa may disappear (azoospermia) or they are much reduced in number (oligospermia). If the disease is neglected, aspermia may result (Scholtz). In most cases the prognosis is good, and complete restoration of function results with a remnant of scar tissue in the testicle. The syphilitic diseases of the genitalia in both sexes—the bladder and the urethra are exceedingly rare—are surgical affections, and their con- sideration is therefore omitted. In passing, it may.be said that they offer favorable prognosis. Syphilis of the Bones and Joints Syphilis of the bones and joints belongs to the domain of surgery. Syphilis of the Muscles (Myositis) The> various forms of specific myositis all yield to treatment. When neglected, atrophy may result. Syphilis of the Respiratory Organs Nasal Syphilis.—We have already, in connection with the considera- tion of gummatous deposits, considered nasal syphilis. The remaining nasal lesions are surgical, and offer favorable prognoses only when treated early. The destruction of tissues goes on unobserved, insidiously, until there is irreparable injury and deformity. Labial and pharyngeal gunv- mata may cause tissue loss, and the deep ulcerations of the pharynx may lead to adhesions and consecutive symptoms. In smokers these lesions may heal slowly, and leukoplakia with mucous patches may be constantly present in such mouths during many years. There are occasional cases of malignant syphilis in which these lesions refuse to yield to any form of treatment: glandular enlargement increases, there is a hard infiltration of the glands (sublingual and submaxillary) PROTOZOAN INFECTIONS 33 with invasion of the surrounding tissue, ultimate breakdown of tissue, increasing anemia, and final cachexia—the patients dying with all of the symptoms of malignant disease absolutely uninfluenced by any treatment, as already mentioned. These cases are among the most rebellious which we have encountered in connection with syphilitic disease. Laryngeal Syphilis.—The appearance of syphilitic laryngeal lesions is at once associated with subjective symptoms, which in consequence, us- ually receive early and successful treatment. The larger number of lesions are of secondary origin. Gerber reports that laryngeal syphilis represents 4.5 per cent of syphilitic lesions and 3.6 per cent of all diseases of the larynx. The gummata of the larynx when neglected, as they are found in the tertiary stage, may lead to deep and irreparable ulceration, cicatrization and malformation, due to adhesions. Stenosis of the glottis and cartilaginous destruction may complicate and add to the dangers. Suddenly arising edema of the glottis in occa- sional cases, may prove life-threatening, and unless promptly relieved ends fatally. This may folloiv the injection of salvarsan and prove to he a true Ilerxheimer reaction; a fact of enormous importance. Relapses of laryngeal syphilis are frequent, though the ulcerative process usually yields to treatment promptly. Syphilis of the Bronchi and Trachea.—Bronchial and tracheal syphilis is rare. Occasionally there are secondary ulcerative lesions which yield promptly. Tertiary lesions of the bronchi and trachea may, if undetected, lead to ulceration and stricture with serious results. Syphilis of the Lung.—Syphilis of the lung is rare, and is an evidence of tertiary disease. It may be either gummatous—usually multiple—or it may be interstitial, and lead to chronic pneumonia. (See Interstitial Pneumonia; also the chapter on Tuberculosis showing the influence of syphilitic infection on the prognosis of pulmonary tuberculosis, where this subject is fully considered). Gummata of the lung are favorably in- fluenced by treatment and offer a fairly good prognosis. Widespread interstitial changes in the lung are but little influenced by treatment. Such cases offer the same prognosis as do the other chronic types of pneu- monia (See Chronic Interstitial Pneumonia). Syphilis of the Spleen The spleen may be enlarged during the secondary stage; there is usually fever and an exanthematous eruption. Hoffman claims to be able to demonstrate the Treponema in the spleen by puncture at this time (Scholtz). This enlargment is not significant prognostically. Gummata of the spleen accompany similar liver deposits, and offer the same prognosis as does liver syphilis. The spleen may be enlarged, or 34 SPECIFIC INFECTIOUS DISEASES the gumma may be so located as to cause no great change in the form or size of the organ. With lues maligna, the spleen may undergo amyloid degeneration. This is a part of a general process in which liver, kidney and blood-vessels are involved. The prognosis is unfavorable. Most forms of syphilitic disease of the spleen are evanescent and offer good prognoses. With congenital lues there may be chronic enlargement of the spleen with characteristic anemia. This may develop early. The spleen may increase to ten times its normal weight (Aschoff). These cases are amenable to treatment: many make permanent recoveries. When enlarged spleen is coincident with hepatitis in the subject of congenital syphilis (syphilis hereditaria tarda), the prognosis is not good. Syphilis of the Digestive Tract Syphilis of the Rectum.—The rectum is more frequently the seat of specific lesions than any other part of the digestive tract, and these may be present during any stage. Primary lesions are occasionally found in the rectum which lead to ulceration, and make differentiation difficult; such lesions heal without leaving remnants. Secondary rectal lesions offer a good prognosis; the mucosa is not permanently damaged and heals promptly under treatment. Tertiary lesions may cause deep changes and stricture if neglected. There may he simple gummatous deposits with ulcerations, or a pro- ductive proctitis with considerable thickening and persistent subjective symptoms. The connective tissue proliferation with accompanying thick- ening and ulceration in the infiltrating form of specific proctitis is often rebellious to treatment; in some, the rectum is finally converted into a thickened, uneven, and narrowed tube with stricture formation periproc- titis, consecutive anemia and resulting chronic invalidism. Syphilis of the Stomach.—The dyspeptic symptoms of the secondary stage are evanescent. Tertiary lesions when present, rarely cause symp- toms which lead to their detection. Fournier has reported such cases, and recently Jerome Meyer has made an exhaustive review of this subject. We know of no serious results which have followed the stomach lesions of syphilis in our practice. Possibly an occasional gastric ulcer may be of syphilitic origin. Syphilis of the Esophagus.—Esophageal ulcers are rare and usually heal; in exceptional cases stricture of the esophagus has been found in syphilitics, without the history of previous ulceration. Syphilis of the Intestines.—Intestinal lesions of specific origin are also exceedingly rare. When suspected, without positive history, the Wassermann reaction and a therapeutic test may be needed. We have had no experience with intestinal syphilis. PROTOZOAN INFECTIONS 35 Syphilis of the Nervous System There are inviting factors which lead to syphilis of the nervous sys- tem ; among these are alcoholic excess, overwork, and the worry which is associated with the stress of modern life (Edinger). The influence of these factors is denied by some, but the weight of experience strengthens the contention that they do exert a powerful influence. The prime factor, as will be accented in considering cerebral syphilis, is insufficient or faulty treatment during the early stages of the infection. The mild early infections, because of their rapid relief and short treatment, are oftener followed by nerve syphilis than are those with the more serious initial lesions. The lesions of the nervous system (excluding paresis and locomotor ataxia) may appear early or late: the average time is between one and four years after the primary infection. With our present method of treatment it would appear that the early cases, radically treated, will prove to be the more tractable. At least 15 to 20 per cent of all syphilitics—until the introduction of salvarsan and the modern treatment of syphilis—developed specific dis- ease of the nervous system. It will require at least two decades of observa- tion to reach conclusions which justify figures based on the newer therapy of Ehrlich and mercury. The most encouraging statement which we can make at the present time is that the outlook seems encouraging. If the recently made observations of ISToguchi which seem to prove the pres- ence of the Treponema pallidum in the brain of paretics are corroborated, paresis and tabes must be included among the tertiary lesions of syphilis. Syphilis of the Spinal Cord.—The manifestations of syphilis of the cord are numerous, and it is exceedingly difficult to offer a single clinical picture which includes all of its possible manifestations. In considering the prognosis of the lesions of the nervous system, especially of the cord, it must be remembered that there is no proof that syphilis ever causes any of the functional diseases of the nervous system. Spinal syphilis tends to indiscriminate lesions with the inclusion of meningeal and cerebral changes. Spinal syphilis as shown by lumbar puncture is a frequent complication of tertiary syphilis; its diagnosis can be positively established by the Wassermann reaction of the blood and the examination of the cerebrospinal fluid. There are occasional cases of spinal syphilis which cause positive symptoms within one month of the initial infection; as a rule from three to five years lapse before the spinal lesions of syphilis develop subjective symptoms. Spinal syphilis during its course is characterized by remissions and exacerbations; for this reason threatening symptoms do not have the same prognostic significance as they do with non-syphilitic disease of the cord in which the prognosis is less favorable. With spinal syphilis, the multi- 36 SPECIFIC INFECTIOUS DISEASES plicity and incompleteness of symptoms are characteristic. Oppenheim accents “the instability, the coming and going of symptoms.” Paresis of one or both legs may develop suddenly, and promptly increase to para- plegia, or paresis of one limb may remain. Spinal syphilis is a protean disease: its typical form includes sensory and motor symptoms—usually specific, partial paraplegia—with bladder invasion in some cases. Oppen- heim describes a “pseudotabes syphilitica,” in which the disease extends to the posterior roots and column. So far as life is concerned, the prognosis of the majority of these cases is good; complete restitutio ad integrum is not often reached, for there are secondary changes which result from compression and scar tissue, and in cases which mend, are likely to leave permanent weakness of the lower extremities. As a rule bladder function is restored in the favor- able cases. There is always danger in these cases of sudden and severe exacerba- tion of symptoms, associated meningo-myelitis; the brain symptoms may suddenly gain the ascendency, and death follows within a few days or weeks. The prognosis is always graver in those cases in which brain symptoms are present either from the beginning, or develop gradually or suddenly. Such cases may develop and lead to death during periods of latency. I feel that, with the positive results of cytological examinations;— the four reactions, i. e., (1) Honne reaction (globulin + Phase I (2) Wassermann reaction (within the blood) (3) Pleocytosis (lymphocy- tosis) (4) Wassermann reaction (in the spinal fluid)—cases will come under earlier treatment, and the prognosis will be accordingly improved; that there will in consequence he fewer advanced cases and less perma- nent damage. Cases in which there are far-reaching changes in the arteries (endar- teritis obliterans) and veins, lead to myelitic softening and permanent loss of function. Spinal syphilis may run its course with all of the symptoms of an acute dorsal or dorsocervical meningitis. In these cases the prognosis depends on the extent of the specific changes, the stage of the disease, the reaction to treatment and the strength of the patient. We have seen a number of cases in which recovery followed; some of our cases devel- oped cerebral symptoms and died. In one, the spinal symptoms yielded, the patient fell into a somnolent condition, in which she remained during a number of weeks, and under rigorous specific treatment (mercurial inunction), recovered completely. Spinal lesions which limit themselves to the nerve roots and meninges, without involving the substance of the cord, offer a good prognosis in a large proportion of cases. These are the more favorable cases of spinal lues. Whenever the cord substance has degenerated the prognosis for res- PKOTOZOAN INFECTIONS 37 toration of function is bad. Paraplegia of short duration, promptly subjected to treatment, offers a fair prognosis. The prognosis of specific spinal paralysis is materially influenced by its extent and the time of its existence. Spastic contractures with such paralysis, and exaggerated reflexes argue against relief by treatment. A large number of the cases of spinal syphilis included in our con- sideration, correspond exactly with the complex now known as “Erb’s syphilitic spinal paralysis” to which Erb called attention in 1892. The paralyses are always spastic; the tendon reflexes are exaggerated; the tension of the muscles themselves is not markedly increased. There are paresthesias and girdle sensation without pain, save in occasional cases. The bladder and rectum are involved in advanced cases. Erb’s syphilitic paralysis is chronic; it tends to improve; there are long periods of remis- sion and in many cases the process remains stationary—covering a period of many years. Relapse, years after improvement or cure, is not infrequent. There are cases of spinal syphilis which remain uninfluenced by any treatment, progress either insidiously or as may happen, run an acute course, ending in a few weeks. Acute tertiary lesions of the spine added to so-called metasyphilitic disease of the nervous system offer an unfavorable prognosis. Hereditary types of cerebrospinal syphilis may lead to indiscriminate and chronic lesions which are hut little influenced by treatment; occasion- ally Oppenheim claims to have seen satisfactory recoveries. Syphilitic Peripheral Neuritis.—There are occasional forms of syphi- litic peripheral neuritis ; the ulnar nerve is invaded by predilection. Syphilitic poison does not show marked affinity for the nerve trunks but we have met a number of cases which prove the possibility of such invasion, in all of which, the prognosis was good. Evidences of compression of separate nerves of the periphery, due either to the pressure of specific exostoses or to gummata, may yield to treatment. References Adler (Isaac). New York Med.

Cerebral Syphilis.—The frequency and great importance of syphilitic infection as a cause of grave disease of the nervous system is promptly appreciated when we consider the results of lumbar puncture, which offer positive evidences in characteristic change in the fluid, of the existence of such complication. The results in over 1,400 lumbar punc- tures made and reported by Dreyfus at the Stadtisches Krankenhaus in Frankfurt a/M. are instructive. It was found that during the early period of syphilitic infection the lumbar fluid showed positive involve- ment of the nervous system (brain and spine) in 80 per cent of all such cases, and that 12 per cent of all latent syphilis showed positive syphilitic disease of the central nervous system in characteristic changes in the lumbar fluid withdrawn. By this method therefore—the appreciation of the significance of its revelations and the rigorous modern treatment of the disease—the prognosis of cerebral and all metaluetic infection is being favorably influenced. In a lecture which Ehrlich delivered (Jan- uary 16, 1914) on the difficulties which he Avas forced to overcome in bringing his remedy to its present usefulness and safety, he made the positive statement that, guided by the results of lumbar puncture, the PROTOZOAN INFECTIONS 39 clinician was now in position to positively prevent the development of paresis and tabes by the intensive treatment of the infection. General Consideration oe Cerebral Syphilis.—The separate types of cerebral syphilis offer a varying prognosis, yet it may be wise in a work of this character to follow the example of Xonne as set forth in his lectures on syphilis of the brain, to devote a short chapter to the gen- eral consideration of the subject. It may be assumed that all types of syphilitic disease, as it invades the brain, are of serious import and frequently lead to death; often, to a chronic state of complete or partial incapacity persisting during years; while in a number of cases the disease may be followed by complete restoration to health—physical and mental. It may be assumed further that syphilis of the brain offers a more favorable prognosis than most non-syphilitic diseases of that organ, including more particularly brain tumor, abscess, multiple sclerosis and degenerative changes associated with paralysis; this is true when the diagnosis is made early. Comparing the results of the operative treatment of brain tumors, we find, in the event of the prolongation of the life of the patient, that recovery is not likely to be complete; that as a rule the symptoms have not been materially relieved. Single abscess of the brain is rare; usu- ally there are multiple lesions; as Ronne emphasizes in his comparison of the prognosis of these conditions, there is likely to be secondary menin- gitis. Multiple sclerosis and secondary paralyses lead to death sooner or later, either directly or frequently indirectly, from distant invasion—- heart, lung, sepsis, etc. These facts justify the statement above made that specific brain lesions when recognized early offer a much better prog- nosis than do those of non-specific nature. Paresis is not included in our consideration of brain syphilis, this will receive separate treatment. We wish to include in this chapter, brain syphilis in which the symptoms are dependent upon specific menin- gitic invasion, gummatous infiltration and specific arteritis. Fournier reports that of his cases are cured, | are materially improved, and £ die. In Rumpfs analysis of 34 cases he found 31 justifying conclusions; of these latter, 5 died, 8 remained incapacitated and sick, improvement followed in 6 cases, and 12 made full recoveries. Hjelmman on the other hand holds that his experience justifies the conclusion that one-half of his cases proved fatal or fell into hopeless conditions, that the fully cured cases were not above 25 per cent, while in the remaining cases there was only partial improvement. My experience justifies the conclusions that have been advanced by Fournier and Rumpf. The time of recognition of the disease becomes an important factor; in no other disease of the nervous system is this more vital. Further, it must be agreed that our free recourse to modern methods of diagnosis, including blood tests (Wassermann) have influ- 40 SPECIFIC INFECTIOUS DISEASES enced the prognosis of cerebral syphilis very favorably, and our statistics are therefore more encouraging than ever before. The examination of the spinal fluid shows that there is lymphocytosis, the globulin reaction, some leukocytosis and the positive Wassermann reaction. The albumin content is slightly increased. Pressure increased. Phase /, or the globulin reaction with the saturated ammonium sul- phate solution, is only present when there are symptoms of central nerv- ous disease. Decided change in the lumbar fluid after treatment and a return to a negative Wassermann may be interpreted as being favorable. From both hospital and private practice we are able to furnish many examples of cerebral syphilis in which there has been no return of symp- toms during many years—varying from two to twenty, and even longer. It must be further conceded that with increased diagnostic ability we have traced a large number of cerebral symptoms to syphilitic infection, have treated these rigorously, and have in consequence materially changed our statistics. Adopting, as does the modern clinician the two underlying pathologic conditions as the leading causes of symptoms in cerebral syphilis—the first so thoroughly described by Virchow in 1858, which includes those lesions of gummatous nature with meningeal invasion, and the second, which proves the presence of specific arteritis included in the classic de- scription of Ileuhner in 1874—it becomes possible to plant our diagnosis, prognosis and treatment, upon a safe foundation. The analysis made by Haunyn of his own 88 cases and 325 collected from medical literature (total of 413 cases), proves profitable and inter- esting. Haunyn considers cases “cured” which show no recurrence after five years of apparent health. He found seven such cases in Caspary’s material, 3 in Fournier’s; his own included 10 cases; while Oppenheim in his monograph reports seven cases of complete cure 5 and 10 years after the last attacks. Honne presents a material of 124 cases of cere- bral syphilis in which symptoms were limited absolutely to the brain. Of this number he was able to follow only 22 cases 5 years, 4 cases over 5 years. Of this latter number two cases followed six years, one seven, one eight years—all remaining without recurrence of symptoms. It may be accepted as true that in the majority of cases supposedly cured, unless treatment continues to be rigorous and the patients are prop- erly led and safely guarded, they fall into the larger class of the partially cured. My experience justifies the conclusion, that cerebral syphilis which has remained uncontrolled or untreated during a period sufficient to lead to paralysis with associated degeneration of brain tissue, whatever the type, is never fully cured; and though treatment may improve existing symptoms in a measure, the damage is permanent and the patient often develops sudden exacerbation which may lead to death. PROTOZOAN INFECTIONS 41 Many cases live for years with symptoms of secondary degeneration. Some are tied to a mattress grave. Neurologists are agreed in considering the prognosis of cerebral syphilis, that in no cases apparently cured can we be certain of freedom from relapse. “Syphilis never dies, it only sleeps” (Nonne). Relapses may include acute endarteritic attacks, spe- cific meningitis, fresh gummatous deposits; and these may alternate with each other in a single case. I have seen long periods lapse between attacks; in malignant cases one type may follow the other with but short intermission, patients finally yielding in coma to specific meningitis. The study of our own material justifies a more serious prognosis in the cerebral syphilis of advanced, than during early life. Age has seemed to be without marked influence until about the 45th to 50th year, after which, because of greater tendency to arterial degeneration, resistance to treatment has increased and its effect has become less efficient and slower. (Ricord, Fournier and Mingazzini report similar experiences.) Malignant types of brain syphilis are not infrequent among young sub- jects; many of these are found with the added depressing effect of dissi- pation in venery and alcohol. Interval Following Specific Infection and the Development of Cerebral Syphilis.—Long postponed cerebral syphilis offers a less favorable prognosis than does the development of brain lesions before the end of ten years (Hjelmman, Naunyn, Nonne). Heredity does not seem to influence the prognosis of cerebral syphilis. Neuropathic tendencies have not invited or influenced the development of the brain complication. Tuberculous and anemic individuals, the cachectic and generally re- duced—particularly those who, weakened by alcoholic excess, are not good subjects—offer scant resistance to the advance of cerebral lues. It has seemed to us that the most malignant types of cerebral syphilis met in our practice have followed alcoholic meningitis or wet brain, which in turn complicated delirium tremens. Most of these were seen in hos- pital wards; were neglected and among the lower classes. Tarnowsky found in 100 cases of pronounced cerebral syphilis, 43 chronic alcoholics, many neurasthenics, some cases of skull injuries, and a good number of patients overtaxed mentally; and he believes that these factors are of paramount importance in the prognosis of the disease. This would also corroborate the theory of Edinger. My experience does not include a single case in which I have reason to believe that trauma was a provo- cative factor, or directly influenced prognosis. The author is in accord with Byron Bramwell who has demonstrated the fact that the graver forms of nerve and brain syphilis follow the milder types of the initial disease. This is simply due to the early disap- pearance of visible lesions and the resulting neglect of treatment of these milder cases. Fournier believes that there is a form of syphilis which by 42 SPECIFIC INFECTIOUS DISEASES predilection attacks the nervous system: “syphilis a virus nerveux That there are such cases, there can be no doubt. They may appear early or late ; they are likely to remain unaffected by treatment. They may follow the so-called milder infections or cases which show malignant tendencies ah initio. The location of the initial lesion has not seemed to influence the prognosis of any specific complications in our experience. Rational and early modern treatment has during the last five years materially influenced the prognosis of cerebral syphilis and all nerve com- plications of syphilis, and unless I misinterpret my experiences, has already reduced the number of these cases. In this connection the state- ment of ITjelmman is of vital importance, if correct: “In from 82-88 per cent, patients with symptoms of cerebral syphilis have had either no treatment or insufficient treatment,” and he believes as we all have reason to do, that in the majority of these cases rational treatment would have prevented the serious condition. There will always be a remnant of cases in which, in spite of early and persistent treatment, syphilitic lesions whether cerebral or not, will re- main rebellious and refuse absolutely to yield. In the majority of these, careful search will reveal the cause, but the therapeutist will be unable to antagonize it successfully. RTonne, however, believes that cases of brain syphilis offer no better prognosis, in spite of the fact that’ they were scientifically treated—mercury, etc., administered during several years— than do those cases in which the early treatment was neglected or entirely omitted. Cases of specific localized meningitis associated with long pe- riods of somnolence, frequently remaining unrecognized—splendidly pictured by Buzzard—offer a very favorable prognosis. To the inexpe- rienced, the clinical picture may appear exceedingly alarming. Haunyn, TIjelmman and Oppenheim place basilar meningitis of specific origin in a class offering a good prognosis (71 per cent). These cases, it has been our experience, may relapse, but in the end they seem to make good recoveries. * Diffuse deposits do not as a rule offer an encouraging outlook. The changes are not limited to the brain; there are likely to be indiscriminate lesions in distant nerve tissue. The early diagnosis is not easily made; the cases are therefore misunderstood during considerable periods. Syphilitic epilepsy with focal symptoms is in the majority of cases favorably influenced by treatment, and recoveries are not infrequent. Early recognized single gumma will in most cases show marked im- provement under treatment, and while a complete anatomic cure may not be certain, clinically the large majority of these cases has yielded and has remained without serious complications, though in none does the prog- nosis justify cessation of eternal vigilance. I have already referred to the Huebner type of specific endarteritis. Gummata of the arteries are not of frequent occurrence. In the Huebner PROTOZOAN- INFECTIONS 43 type of arteritis, the inflammatory infiltration of the vessel wall may be absorbed, the narrowing of the lumen may not be materially reduced, but the extent of brain tissue involved is likely to be limited; and though it may net regain its power, there will as a rule be compensation sufficient in most cases to supply function. I have seen cases diagnosticated as arteritis specifica, with hemiplegia, which have yielded after several weeks of persistent symptoms. In the majority of these cases the patients recover with clear intellect and memories, are undisturbed, though there may in the severe cases, be some motor weakness with few sensory symp- toms left. Hemiplegia, however, with syphilis should never be lightly considered; it is always serious. In cases associated with renal changes, chronic nephritis and hyper- tension, the prognosis must of necessity be grave. Recurrences are not infrequent, if there are many or if there is con- tinuous progression of arteritis, the patient falls into a pitiful condition— paretic and hopeless. Cases of specific arteritis (Huebner) do not as a rule die suddenly or early. When the process invades the basilar vessels, the prognosis is most grave because of the invasion also of the higher psychic centers. It is occasionally difficult to differentiate paralysis of the motor oculi of arteritic and gummatous origin. The former offers a less favorable prognosis so far as complete restoration of function is concerned. Ordi- nary syphilitic paralysis of the motor oculi, usually gummatous, is likely to disappear completely under treatment. Optic neuritis (choked disk) does not argue against the possibility of recovery; advanced optic atrophy with cerebral syphilis is always evidence of serious disturbance, and the prognosis is consequently bad. Long continued paralysis of the cranial nerves, with syphilis of the brain, offers an unfavorable prognosis for restoration of health or function. References Bramwell (Byron). Clinical studies.

Late Manifestations of Tertiary Syphilis of the Cord and Brain—So-called Meta- syphilitic Disease The manifestations of the tertiary stage of syphilis which I include in my consideration, have until the present time been considered to be metasyphilitic—not dependent upon syphilis primarily—but the condi- tions were supposed to develop in syphilitic subjects in whom it was assumed that the brain and cord were possibly vulnerable, or that for some unknown cause degenerative and atrophic changes were invited. With increasing clinical experience and pathological study, a strong suspicion had arisen in the mind of experienced neurologists and syphilog- raphers that the relation of metasyphilitic diseases to specify syphilitic infection was one of dir.ec-t cause and effect, and during several decades the French school led by Fournier, and the German school of which Erl) was the Nestor among the neurologists, fought an active battle to establish the direct pathogenic relation of syphilis to tabes, paresis, and tabo- paresis. Statistics gathered from the authoritive medical centers of both continents strengthened the contentions of Erb and Fournier, that in over 90 per cent of all so-called metasyphilitic disease, a clear history of syphilis could be established and that syphilis therefore was the prime factor to be considered in the prognosis and treatment of these diseases. Even the strong opposition of such authorities as Charcot, Westphal, von Leyden, and J. A. Glasser, did not influence Erb nor Fournier, who, persistently, by their writings and in their clinics, added material to strengthen their views. The profession had registered itself in favor of the syphilitic path- ogenesis of the metasyphilitic diseases and was fully prepared to receive the results of the epoch-producing experiments of Noguchi, which demonstrated the Treponema pallidum in the cord of tabetics and in the brain of paretics. With these positive proofs of the presence of the Treponema, and the results of inoculation experiments by which similar conditions have been produced, and the further overwhelming evidence offered by the positive Wassermann reaction of the blood and by the spinal fluid (withdrawn by lumbar puncture), I feel justified in placing the conditions formerly included among the metasyphilitic diseases in the section on Syphilis. I believe that such classification will do much to justify the intensive PROTOZOAN INFECTIONS 45 treatment of syphilis, and will consequently favorably influence the inci- dence of tabes and paresis; further, I am fully satisfied that the infected, when aware of the true cause of the most dreaded of all of the complica- tions of syphilis, will be more eager than ever before for such radical treat- ment as is demanded in the individual case. We consider: (1) tabes dorsalis (locomotor ataxia), (2) taboparesis, (3) paresis (progressive paralysis of the insane). Tabes dorsalis {Locomotor ataxia) The prognosis of locomotor ataxia has been powerfully influenced by the introduction of the newer methods of treating syphilis, the discovery of the Treponema in the cord and brain of tabetics and paretics, and the revelations of sero- and cytodiagnosis. Several years must lapse before positive conclusions can be justified. The characteristic and constant lesion of locomotor ataxia is the grey degeneration, probably developed after' a limited period of irritation— possibly inflammation, of the posterior columns of the cord. The disease is primarily a system disease of the cord, but its many manifestations soon prove its indiscriminate tendencies. There are occasional juvenile forms of the disease due to congenital syphilis. As a rule tabes is found in the male, three times as often as in the female, and between the thirtieth and fiftieth years, and from 5 to 20 years after infection, with an average of 9 years. Tabes within one to five years after initial infection has in my experience developed rapidly, and has usually entered the ataxic stage early. These cases offer a less favorable prognosis than do those which follow infection after a longer time. In a fully developed case the following conditions may prevail: 1. The membranes of the cord are thickened over the part involved—* more posteriorly. 2. There is flattening of the cord. 3. With degeneration, the posterior columns and nerves are shrunken and atrophied. 4. Connective tissue proliferation in the postero-external columns and posterior horns. 5. The disease attacks the dorsal and lumbar regions by preference. 6. With the onward march of the disease, the postero-internal columns and the posterior horns may be involved. Y. There are likely to be degenerative changes in one or more of the cranial nerves—the optic and motor oculi are oftenest involved. These changes may be either early or late. 46 SPECIFIC INFECTIOUS DISEASES 8. During the terminal stage the anterior horns and the lateral columns may be invaded, leading to atrophy of muscles and contractures. 9. There may be chronic arteritis invading the vessels of the cord and brain. 10. The terminal stage may include paresis or other cerebral lesions •—hemorrhage, thrombosis, pachy—and leptomeningitis, and changes in the ependyma. 11. Aortitis, arteriosclerosis or arteritis are frequent complications, depending upon the same initial cause. The rapid development of arterial degeneration in. tabetics of all ages is often surprising. The artery is uni- formly thickened—shows placque deposits, and aortitis in such cases is usual. The prognosis of locomotor ataxia must include the consideration of its (a) cause; (b) sex; (c) age; (d) possible prophylaxis; (e) location and extent of the degeneration; (f) the influence of the treatment on the symp- toms of the various stages of the disease—initial, ataxic and paralytic; (g) the prognostic significance of individual symptoms; (h) Wassermann reaction of the blood and spinal fluid; (i) the complications. (a) Causes.—In the light of our present knowledge, it is safe to assume that locomotor ataxia is always due to luetic infection. Basing the consideration of the disease upon this assumption strengthens the hope that with the dissemination of knowledge and the radical early treatment of those infected, the late manifestations referable to the nervous system will decrease in the future. Fournier reported that in one thousand cases of locomotor ataxia, he found 92.5 per cent syphilitic. Erb found in 1,100 cases of locomotor ataxia among men in good condition, 89.4 per cent syphilitic; and in 158 workmen, 77.2 per cent syphilitic; 6,000 cases of nervous diseases, other than tabes, show 20 per cent of syphilitics. Congenital and unrecognized syphilis was considered the cause of tabes in the small and unexplained remnant by both authorities; and with our present methods of diagnosis this conclusion is justified. In Germany, Virchow in his Krankhaften Geschwiilsten—a work far in advance of its time—insisted, before either Fournier or Erb had offered their conclusions, that “there is no doubt of the fact that some cases of tabes are syphilitic.” For more complete statistics showing the relation of syphilis and tabes the reader is referred to Honne’s classic work; also Rumpf. The statistics of all large clinics gathered during the past decade fully corroborate the early conclusions of the French and German School. The so-called metaluetic diseases including locomotor ataxia—either by their history, when thoroughly considered, or as the result of cytosero- diagnostic methods—establish syphilis as the cause in most cases (92 to 97 per cent). PROTOZOAN INFECTIONS 47 Predisposing Factors.—There are factors which predispose syphi- litics—acquired or congenital—to tabes; among these are improper treat- ment of the initial infection, hereditary tendencies and diathesis, ex- posure, excesses in alcohol and venery, traumatism, overwork, and worry. The theory of Edinger that the various parts of the nervous system yield to disease in proportion to the fatigue (exhaustion) resulting from over- work and the many other factors of life which, through the emotions and long continued wear and tear of an organ, prepare for surrender and ulti- mate pathologic degeneration—is plausible and deserves consideration. (b) Sex .—The influence of sex on prognosis is insignificant. Collins believes that the disease advances Avith greater rapidity in women; this is not the accepted view. I have found that women fall into the same chronic stages as men and are subject to the same complications. Our cases show a larger number of paralysis of the eye muscles in women. (c) The Influence of Age.—Pathologically juvenile tabes does not differ from the disease as found in the adult; both the symptoms and com- plications are identical though their development 'is different. Syphilis is the cause of juvenile tabes; girls are oftener affected than boys. In juvenile tabes, optic atrophy with consecutive blindness is an early symptom, Avhile lancinating pains are not as frequent as in the adult; the same is true of paresthesias and analgesias. Fully developed ataxia is exceptional; the course of the disease is protracted, but mild (Koester). Blind children are often found in public institutions with juvenile paresis: not an infrequent sequel. There are occasional acute cases which run a rapid course in patients between the ages of twenty and thirty. The younger the adult, the more likely is the process to show rapid progression. One-half of all cases be- tween 20 and 40 progress rapidly. After the fiftieth year, acute cases are unusual and chronicity is the rule. Tabetics often reach old age, as is shoAvn by the statistics offered in considering the duration of the disease. (d) Possible Prophylaxis.—For the future of the syphilitic, the possi- bility of the prevention of the late manifestations of disease of the brain and cord is of the utmost importance. The clinical experiences of the past prove that it is the rare exception for thoroughly treated cases of syphilis during the early and late stages to develop either tabes or paresis. It is the untreated, usually mild cases in which the initial lesions were either hidden, unrecognized, or evanescent, and which received practically no treatment during the secondary stage of the disease, which later develop the most serious complications; and when the nervous system is included, the progression of symptoms is as a rule so insidious as to remain unrecog- nized until grave and irreparable degeneration proves the presence of advanced disease. The further evidence offered by repeated examination of the lumbar fluid during the early stage of syphilis, proves that the 48 SPECIFIC INFECTIOUS DISEASES intensive treatment at once overcomes the incipient invasion of the brain and cord. Dreyfus has demonstrated, after over 1,400 lumbar punctures, that the nervous system, i. e., the brain and cord, gives positive evidences of change in 80 per cent of all cases of early syphilis, and that in 12 per cent of syphilitics the reactions are positive during the late stages. It is the 12 per cent of uninfluenced cases which cloud the prognosis, and these are among the subjects who develop tabes and paresis when one or more of the exciting factors already mentioned prevail. The small proportion of syphilitics who develop tabes and paresis also argues in favor of the prophylactic influence of the radical and intensive treatment of the initial disease. In private practice, where there is an intelligent cooperation of the patient and the physician, I have less than one per cent of so-called metasyphilitic infections to report. The average reported by Scholtz is from 2 to 3 per cent; this includes the material of hospitals, etc. Reumont found 40 cases of tabes in 3,600 syphilitics—1.1 per cent. It is, according to well-digested experience, fair to give almost positive assurance of escape from the late manifestations of the tertiary stage of the disease, provided that the treatment of the preceding stages has been intensive and appropriate. The profession is passing through a period in which positive conclu- sion with regard to the future of the syphilitic treated with salvarsan and mercury combined, cannot be given; the time for a safe forecast has been insufficient. To be certain that the late manifestations including tabes will be entirely prevented will require a period of observation, covering at least three decades. The indications, however, are favorable and those who have had the largest experience justify an encouraging outlook. Ehrlich believes “that the early intensive treatment of syphilis with sal- varsan and mercury will practically prevent the occurrence of tabes, taboparesis and paresis.” (e) The Location and Extent of the Degeneration.—The prognosis is worse in cases which are associated with multiple or disseminated cere- bral lesions; worse also so far as comfort and progression are concerned, the higher in the spine the degeneration spends its force; bad with cervical and bulbar invasion. The prognosis is absolutely bad when paresis complicates tabes; also with other psychoses. Reference to lesions of the peripheral nervous system, the brain and sympathetic system are found in the separate chapters dealing with these. (f) The Influence of the Treatment on the Symptoms of the Various Stages of the Disease.—We consider an (1) initial stage (neuralgic—pre- ataxic, (2) ataxic stage, (3) paralytic stage. 1. The Initial or Neuralgic Stage.—Locomotor ataxia may re- PROTOZOAN INFECTIONS 49 main stationary in any stage of the disease—oftener in the first stage— with or without treatment. The increasing benign tendencies of certain types of the disease was recognized by Charcot and Brissaud because of the growing frequency of mild cases which show but little tendency to progress, and remain latent or stationary during several decades, in some instances. This fact has led to the conclusion that tabes is less serious to-day than in the past: a fact which unqustionably depends upon the more thorough and scientific treatment of the early stages of the disease. Oppenheim believes that there is in tabes, as in many other diseases, a lowering of the malignancy of the infection with succeding generations. The older neurologists including Duchenne, Romberg, Trousseau and Charcot during his early experiences, as well as Leyden as late as 1878, considered the disease to be always progressive, and rarely recognized the cases which have increased in frequency, with a duration often of 15 to 30 years or even longer. It may be assumed that lack of the diagnostic ear- marks, which we now possess—Argyll-Robertson pupil, Westplial phe- nomenon—allowed some of these chronic cases to remain undetected. There are cases which show no tendency to progress but in which a single symptom remains in the ascendency. Such cases were prominent before the introduction of salvarsan and are still met, though the indi- vidual symptom is now often favorably influenced by treatment. Among the prominent single symptoms of these cases are the lightning pains, altered bladder function, or ocular paralysis. In occasional cases there may be improvement of a number of symptoms during the early period, while one or two symptoms remain unchanged but are not sufficiently severe to incapacitate the patient. In the cases with a single prominent symptom the progress of the disease may be so slow as to be unnoticed, or there may never be extension. Such a case I have had under observation in a banker who has during 30 years continued at his work with limited paralysis of the left motor oculi, loss of deep reflexes, but without pro- gression, and no evidences of incoordination. Another case with limited optic atrophy and Argyll-Robertson pupils has also been watched over 25 years. The patient is now 70 years of age, has retired from his business, is still active in society and is president of a club, able to be about un- assisted with occasional lightning pains as his only troublesome symptom. It is interesting to note that these results w7ere obained before the days of salvarsan. Occasionally after a period of severe symptoms during the initial stage, with incoordination and sensory symptoms, improvement may follow suffi- cient to make it possible for the patient to return to his work without the advent of new symptoms during long periods. Such cases, unless they die of intercurrent disease, finally progress gradually and after 25 to 30 years pass through the ataxic to the paralytic stage. Cases in which gastric crises are the prominent feature of the incipient 50 SPECIFIC INFECTIOUS DISEASES stage, with modern treatment are made comfortable during long periods. There are exceptions to this statement, but in the majority of such cases it is justified. In most cases it is difficult to determine the exact time of the advance from the initial to the second stage, for ataxic symptoms are not uncom- mon during the first year; and in a number of cases there are, as already suggested, cycles during which symptoms may increase followed by im- provement and stationary periods. As a rule, the return to the condition which existed before the exacerbation, with or without treatment, is m>t complete and there is a remnant of symptoms which shows progression of the lesion. In offering a forecast of the effect of treatment on the separate stages of the disease, I can give only general conclusions, but would refer the reader for detailed information to (d) the significance of the separate symptoms on prognosis. The initial stage varies in length and symptoms in different cases. There are tabetics who continue with but one or two symptoms during many years, without noticeable progression; the condi- tion is stationary, uninfluenced by any treatment. There are cases in which there is simply a loss of the patella tendon reflex without severe crises, occasional bearable pains, and some ocular paralysis. Such cases permit the patient to continue at his work without marked inconvenience. The reaction of the separate symptoms to treatment and the tendencies of such cases we consider in connection with the separate symiptoms; but the general statement is justified that these cases react favorably, so far as sensory symptoms are concerned. The cases in which the initial stage includes loss of patella tendon reflex, Argyll-Robertson pupil, lightning pains, analgesias, and paresthe- sias with girdle sensation, ocular paralysis, and early gastric crises may remain stationary during long periods, but as a rule are slowly pro- gressive. If during the initial stage urinary symptoms are superadded, the chances for control of symptoms or latency are reduced. Early ataxia during the incipient stage and sudden increase of symp- toms is always unfavorable; for it indicates deep involvement in a degen- erative process of the postero-external, possibly the cerebellar tract, and this condition is not easily influenced by treatment. ISTo treatment permanently influences advanced degeneration in any stage; inflammatory changes in the incipient stage may be improved. Improvement does not mean cure, and it is not as a rule held unless repeated injections and interval treatment is continued. The examination of the blood and spinal fluid for the Wassermann reaction and for other characteristic cellular conditions proves of inestim- able value for treatment and prognosis during the initial stage. The careful observation of the effect of the combined salvarsan and mercury treatment of the early stage of tabes proves the urgent need of PKOTOZOAN INFECTIOUS 51 prolonged treatment—repeated injections of sufficient size—before conclu- sions for prognosis are justified. So far as life is concerned the cautiously controlled treatment is practically without danger. During the incipient stage in a large experience, we have had not un- toward results. Herxheimer in a recent lecture reported 40,000 injections of salvarsan given to 11,000 patients in the Frankfurt Hospital under his supervision without a death, and Dreyfus reports 3,000 intravenous in- jections in 250 patients with hut one serious sequel and that was diagnos- ticated as meningo-encephalitis with recovery of the patient. Medical literature includes a number of deaths resulting from the use of salvarsan, hut these are exceedingly rare during the incipient stage of tabes. In occasional cases the patella tendon reflex, ocular paralysis, pains, and gastric crises are improved. The most encouraging feature of the treatment of the incipient stage of tabes is its favorable influence on the Wassermann reaction, which after one or two injections passes from the positive to the negative phase and often remains negative during long periods in most cases. Occasionally the treatment during the initial stage ct usss a positive reaction from a previously negative phase during a limited period. The most favor a Die cases are those in which the treatment leads from the positive phase to a persistence of the negative reaction. Less favorable cases are those in which after a limited period, there is a return from the negative to the positive reaction. Most unfavorable are those which in spite of treatment, continue to give a positive Wassermann reaction. My conclusions concerning the prognosis of the incipient or first stage of tabes based upon modern treatment prove the possibility of better con- trol of symptoms than by the previous methods, and in a number of cases the sensory symptoms and ocular paralyses have been so much improved as to encourage us to believe that they may be permanently relieved by several cycles of treatment. Marcus, Weber, McDonagh report the return of pupillary reflex after salvarsan with negative from a positive Wassermann reaction. In no single case, however, which I have observed thus far and treated according to modern mlethods, have I been able to banish the manifestations of the incipient stage sufficiently to justify the belief that the treatment did more than postpone longer than could be done by any previous treat- ment, the sensory disturbances with—as already suggested—improvement in other directions. It would seem that there is a strong likelihood of con- trol of symptoms during stationary periods by modern methods. Whether we shall be able to prevent the advance to the ataxic stage cannot be de- cided until our experience has grown and abundant time for observation has lapsed. Increase in weight and improvement of the general condition is the rule after treatment. 52 SPECIFIC INFECTIOUS DISEASES 2. Ataxic Stage.—Treatment has in individual cases improved some of the symptoms of the ataxic stage of the disease. As in the initial stage, so in the ataxic, sensory symptoms have been sufficiently improved to jus- tify the treatment. I have seen patients with both marked and insig- nificant ataxia, who had been incapacitated by severe crises so much im- proved by intensive treatment—salvarsan and mercury—as to return to and remain at their work. Occasionally the patella tendon reflex has been strengthened and with added mechanical treatment and resulting education, incoordination be- came less troublesome. All of these cases require repeated injections at varying intervals if the improvement is to be held. The sensory symptoms wdiile they recur, are less severe. Permanent results are not to be expected. 3. The Paralytic Stage.—Treatment has absolutely no effect in per- manently controlling the symptoms of the advanced and final stage of tabes. Dreyfus claims that no tabetic is so far advanced as not to justify intra- venous injections of salvarsan. The treatment of tabes by means of the intraspinous injection of the salvarsanized serum taken from the patient according to the method of Swift and Ellis has been entirely without effect in our cases. My experi- ence with the method is limited, but the pains following were so severe and the results so unsatisfactory that I have no desire to continue the experi- ment, and do not believe that it offers promise of a favorable influence on the disease. Favorable results are recorded by others; the entire question is still sub judice. Dreyfus offers the following report of his experiences with the salvar- san treatment of tabes:— Leading Symptom. Number of Cases Treated. Materially Improved. Im- proved. Uninflu- enced. Symptoms Increased. Pains 35 20 14 1 Headache, neurasthenia, perforating ulcer, blad- der symptoms 9 3 4 2 Crises 15 7 5 3 Ataxia 18 5 7 3 3 84 per cent. 12 per cent. 4 per cent. Dreyfus reports that some cases with advanced ataxia, which before treatment could neither walk nor stand for any length of time, were able after treatment to walk comfortably. Donath reports similar experiences. Donath’s material justified the following conclusions after the salvar- san treatment: PROTOZOAN INFECTIONS 53 Pupillary reaction returned in 3 of 28 cases Patella tendon reflex returned in 1 “ “ “ Walking was improved in 4 “ “ “ General improvement was manifest in 18 “ “ “ Marked gain of strength in 7 “ “ “ Improved mental state in 9 “ “ “ The reader is referred to the detailed rules given by Dreyfus for treat- ment in his full article (see references). (g) The Prognostic Significance of Separate Symptoms.—The rapid development of several symptoms at the same time during any stage of tabes is unfavorable. Cases in which there are but few symptoms offer a much better prognosis than do those in which there is a multiplicity of symptoms usually dependent upon indiscriminate lesions; these cases show rapid progression. Occasionally with many symptoms, the patient is advanced into the ataxic or from the ataxic to the paralytic stage and falls into a latent but helpless condition in which he may remain during a number of years; or there may be some improvement of one or more symptoms, but not sufficient in the presence of advanced ataxia to return the patient to usefulness. There are many cases which advance to the paralytic stage after steady progression of symptoms in which the ataxia is almost complete, in which the pains cease and the ocular paralyses remain. The mind is usually clear and active in these cases. I have one such case under observation of a man aged 60 who has been in the paralytic stage over 10 years and who is daily wheeled in his chair to his office, where he presides over a large institution as its president; there has been no apparent progression of the process during the past 5 years. In this case the bladder function has been paralyzed over 12 years; catheter life has been well borne. Multiplicity of symptoms does not always signify rapid progres- sion : there are occasional exceptions. Collins’ experience justifies the con- clusion that cases in which the sympathetic nervous system is involved— including crises, trophic disturbances, early troublesome bladder and rectal symptoms—offer the most unfavorable prognosis. With perforating ulcer, arthropathies, and other trophic changes, restitution to the former condi- tions is unusual. I have called attention to the cases in which gastric crises have yielded to modern treatment and there is a strong probability, basing our conclusions on the result of the experiences reported by Drefus and Herx- heimer and our own observations, that a favorable impression can be. made on many of these cases. Gastric crises do not of themselves shorten life. One of our cases is still living in the paralytic stage which has never during 30 years passed long periods without gastric crises; on the other hand, it is not impossible for crises which have continued during many years to cease and never recur. 54 SPECIFIC INFECTIOUS DISEASES Benedikt says: “Gastric crises arc as favorable for prognosis as is the atrophy of the optic nerve.” This extreme statement is not justified, but as Malaise says, it should be accepted to prove that Benedikt saw cases in which early gastric crises were without unfavorable influence. The general condition of the patient is favorably influenced by the long intervals between gastric crises. I have seen surprising gain of weight during these prolonged intervals, produced in some cases by sal- varsan treatment. The development op THE morphin habit by patients with crises of all kinds has limited the usefulness and lowered the resistance of many tabetics in the past. It is a preventable factor and is usually chargeable to the attendant. Modern treatment will prove of inestimable value, reducing the number of morphinists and alcoholics. I have in connection with the prognosis of the initial stage and the subsequent general consideration, called attention to the unfavorable influ- ence of disturbed bladder function. Atrophy of the optic nerve has seemed to many to have an inhibit- ing influence on the advance of ataxia. This fact was accented by Bene- dikt, Gowers, Dejerne, and by Bayley and a host of others. Dejerne con- tended that a blind tabetic rarely developed the symptoms of the ataxic stage. Bayley found that among 12 tabetics who developed optic atrophy early, the onward march of the disease was inhibited in 9. Collins dis- agrees with the above conclusions. Malaise reports that in 73 per cent of the cases of optic atrophy ob- served at the Oppenheim clinic, it developed in the preataxic stage; and that three-quarters of these cases were followed by latency of the tabetic process after blindness; and that in many cases individual symptoms of ataxia were improved or relieved entirely, including urinary incontinence and lancinating pains. In 15 per cent of the cases the disease progressed pari passu with the optic atrophy entirely uninfluenced by the latter. The remnant of cases with optic atrophy advanced gradually to the late stages of tabes. I have seen a number of cases in which optic atrophy was a late development, in which the advanced symptoms of tabes remained entirely uninfluenced. It may be concluded that the fully developed symptoms of locomotor ataxia as a rule persist when once established; that the early development of optic atrophy is not likely to be associated with other severe tabetic symptoms; that in some cases improvement of these symptoms follows advancing optic degeneration; that the statistics offered by Malaise are approximately correct ; that the development of optic atrophy during the terminal stages of ataxia is without influence on the tabetic symptoms. Mott contends that when optic atrophy develops in advanced tabes, it is usually coincident with the progression of serious brain degeneration (pa- resis). Of his cases of optic atrophy which included 10 per cent of all PKOTOZOAN INFECTIONS 55 tabetics, 80 per cent developed symptoms of paresis. This conclusion is not generally accepted. In my experience I have found positive evi- dences of optic atrophy in 12 per cent of our cases of advanced tabes, but of these only few developed paresis. It must be remembered that Mott’s experience deals with hospital and asylum cases, and not with the cases which are met in every-day practice. Ataxia which develops before the end of the third or fourth year of tabes dorsalis indicates progressive tendencies, but is more favorable for life than when it is among the early symptoms of the initial stage or when it develops acutely. Schaffer called attention to tabes inversa in which the ataxia preceded all other symptoms. The prognosis of tabes inversa is more favorable than ataxia which is either acute or develops rapidly in the presence of the usual symptoms of the early stage. From 15 to 20 per cent of all tabetics never develop ataxia. The influence of scientifically directed and supervised exercises on the locomotion of chronic ataxia—Fraenkel and other exercises—is often en- couraging; the improvement is naturally greatest in cases where a suffi- cient remnant of muscles has escaped the loss of coordination, and by edu- cation a degree of compensation is obtained to permit of fair functional ability. Bladder and Rectum Symptoms.—The rule may be accepted that tabetics who are without bladder or rectum symptoms offer a better outlook than do those in whom there is retention, incontinence, or both. But few cases pass through to the paralytic stage without well marked bladder symp- toms. The continuous dribbling of urine may be evidence of retention from an overfilled bladder; in advanced cases it denotes sphincter paralysis as well. The dangers of infection from cystitis are increased by bladder paralyses. Rectal incontinence is rare without bladder paralysis, and occurs only with advanced tabes. Reference is made in this chapter to cases in which retention has not seemed to influence the disease unfavorably; but such cases to escape complications, demand the cautious use of aseptic methods during catheter life. Westphal Symptom.—Westphal symptom, or loss of patella tendon reflex, is one of the earliest of all symptoms and is likely to continue throughout the disease unless extension to the lateral columns finally causes return and exaggeration. In none of my cases has salvarsan treatment permanently changed the knee phenomenon. The same conclusions are justified in connection with the Romberg symptom (swaying with closed eyes) and the persistently present anesthesias, paresthesias and analgesias of the second and last stage. This has not been the experience of all—as has been demonstrated by the statistics of Dreyfus and Donath, quoted in another section of this chapter. 56 SPECIFIC INFECTIOUS DISEASES The loss of the knee phenomenon should not alone be accepted as an indication of far advanced tabes; changed function does not always indi- cate destruction and degeneration. Many cases in which there is loss of this reflex, remain stationary or do not advance materially during many years. Ocular Paralysis.—It is often impossible to correctly determine the nature of the lesion which causes ocular paralysis. In our forecast it is safe to consider most cases of nuclear origin, i. e., central; muscular paralyses are more likely to depend upon central than upon peripheral lesions. The Argyll-Robertson pupil does not often disappear in advanced cases. A number of reliable observers have reported periods during which the light reflex returned after its positive disappearance. Donath found with salvarsan treatment, a return of pupillary reaction in 3 of 28 cases. This is possible in early tabes influenced by intensive treatment, but is not likely in the advanced stages. In considering the paralyses of the cranial nerves, I dilated on the prognosis of the paralyses of the eye muscles (See Paralysis of Ocular Muscles). Early paralysis of the ocular muscles in tabes is not often followed by the rapid progression to ataxia. Years (2 and 3 decades) may lapse, with progression so slow under these conditions, that it is almost unnoticed by the patient. Ophthalmoplegia may disappear under treatment as may the paralysis of separate muscles; this is true of the early stage only, as a rule. 20 per cent of tabetics have ocular paralysis. Hypotonia is evidence of advanced tabes and is a symptom of the paralytic stage. Impotence.—Impotence, once present, is likely to continue. One- third of all tabetics are impotent by the end of the seventh year of the dis- ease. When impotence develops early in the disease it is evidence of rapid progression; such cases offer an unfavorable outlook. Incontinence of urine early in the disease, often late, is usually fol- lowed by impotence. In some cases sexual intercourse is impossible because of distortion of the penis, and occasionally hemorrhage into the corpus follows the act. Progression of the disease is likely to be rapid when the tabetic in vdiom the disease is fully developed is excessive in sexual indulgence. Emotion, long continued worry, any psychic disturbance which makes a profound impression or is continuous, react unfavorably on the tabetic; under these conditions the progression is often surprisingly rapid. Heavy manual labor always causes increase of symptoms denoting the unchecked advance of the disease. With some acute cases the progression is so rapid that the patient is promptly plunged into the paralytic stage, having skipped the initial and ataxic periods. If such rapidly advancing cases of acute tabes do become PROTOZOAN INFECTIONS 57 stationary, it is only after they enter the paralytic stage. This happens occasionally, but the paralytic stage under these conditions is as a rule shorter than in other cases—chronic ab initio. Perforating Ulcer.—In none of our cases have these trophic changes failed to recur after they were healed or partially healed, when the patient was on his feet much of the time. Perforating ulcers may not always recur in the same location but as a rule they do, or in the immediate neighborhood. They may form either in the ataxic or paralytic stage. Most of our cases were found in the ataxic stage and in men who were on their feet much of the time. They do not affect life directly, save as sepsis develops from their neglect. Arthropathies.—Arthropathies are trophic changes in which there are characteristic joint enlargements and destructive, usually non-suppura- tive changes. They develop during the advanced stages of the disease (oftener in the knee joint) and are beyond control by any known treat- ment. Our cases of Charcot arthropathies and spontaneous fracture have been far advanced and paralytic; other trophic changes add to make the prognosis bad. (h) The Wassermann Reaction of Blood and Spinal Fluid.—We have already mentioned the importance of the Wassermann reaction of the blood and the spinal fluid. It must be remembered that with progressive tabes the blood may give a negative reaction, while the lumbar fluid will be likely to give positive results. With tabes, which is active, there are 1. Increased pressure in the subarachnoid space 2. Phase 1 (Ronne), globulin reaction 90 to 95 per cent 3. Lymphocytosis: 85 to 90 per cent 4. Albumin presence: slight or normal. With Argyll-Robertson pupil and previous syphilitic infection, with- out syphilitic infection, without positive subjective symptoms of tabes, Phase 1 is present, albumin-(- (occasionally normal), lymphocytosis-f- (in most cases, though it may be absent). Plaut, Pehm and Sehottmiiller made the positive statement that with negative Wassermann reaction of the lumbar fluid and the Argyll-Robert- son pupil, without other symptoms, it may be assumed that the failure of the pupil to react to light (Argyll-Robertson) is the expression of a process which has run its course and is favorable. When with symptoms of loco- motor ataxia the four factors above mentioned are absent, this happens (according to Plaut, Rehm, etc.) in 7 per cent, 50 per cent of these cases may be considered to be stationary. The blood serum of tabetics offers positive reactions in over 70 per cent of cases. The lumbar fluid shows a positive Wassermann reaction in almost all cases of active tabes; with progressive paresis and taboparesis, the reaction is present in practically 100 per cent of all cases. 58 SPECIFIC INFECTIOUS DISEASES The lumbar fluid and the blood therefore offer valuable data for the prognosis of tabes, and during the incipient stage demand repeated tests that the effect of treatment may be watched. (i) Complications.—The combination of independent specific disease of the nervous system during the existence of locomotor ataxia is possible. Gummata of the brain have been reported, specific and suddenly arising meningitides, and a variety of other lesions. Each deserves separate study, but all influence the forecast unfavorably. Naturally the rapid conversion of a system disease (locomotor ataxia) into one with far-reaching indis- criminate lesions (dissemination) in brain, cord and peripheral nerves influences the case unfavorably. Tabes complicated by trauma is usually progressive; its course is more rapid than is the average case, and bladder symptoms are often early and exceedingly troublesome (cystitis, etc.). Acute or chronic alcoholism always influences tabes unfavorably. These cases are usually neglected; they suffer from infected bladders, con- stitutional symptoms are numerous, and brain lesions (wet brain) often cause death. With chronic alcoholism it is safe to conclude that tabes is not stationary, but progression is certain and leads to the terminal stage if the patient does not die of intercurrent disease (pneumonia) sooner than do the non-alcoholic cases. Arteriosclerosis; Arteritis; Aortitis.—Among the most frequent complications of tabes is arteriosclerosis and specific aortitis. In some cases the process in the arteries is rapidly progressive, is associated with hypertension and nephritis. It may be safely concluded that arterioscle- rosis of the mesenteries with heightened blood pressure is a frequent factor in causing the vascular spasm which leads to gastric crises. Advanced evidences of arteritis are common in young tabetics. Aneu- rysmal dilatations are also a relatively frequent complication of locomotor ataxia. Osier reports 20 per cent of aneurysms in some series of tabes. Pneumonia.—Pneumonia (croupous bronchopneumonia and aspira- tion pneumonia) is among the more frequent causes of death of tabetics. Any form of pneumonia in the tabetic is serious: the majority die. Paralysis agitans.—My material includes two cases in which loco- motor ataxia was finally (ataxic stage) complicated by paralysis agitans, in which the former disease seemed uninfluenced. Basedow’s Disease.—Oppenheim mentions Basedow’s disease as a complication; we have no similar experience to report. Surgical Operations.-—Tabetics bear surgical operations badly; this is particularly true of those cases in which there is advanced arteritis. Infections and Tuberculosis.—Acute infections and tuberculosis are usually serious in tabetics. They offer little resistance to toxemia, par- ticularly when in the last stage. Acute invasion of the Medulla oblongata.—There are occasional PROTOZOAN INFECTIONS 59 cases of tabes in which the disease suddenly attacks the medulla oblongata, in which there are at once evidences of vague paralysis in rapid pulse and hyperpyrexia: the sensorium is promptly blunted; coma and death may result in the course of a few days. The pathologic conditions are either vascular, degenerative or both. Inflammatory lesions which cause these symptoms are infrequent. Epileptiform Seizures; Vertigo; Hysteria.—Cases of advanced tabes are occasionally complicated with epileptiform seizures or vertigo. Some have periodic outbreaks of hysteria. The epileptiform seizures are usually associated with transitory uncon- sciousness preceding mental disturbances and are followed by a period of memory lapse. The attacks are likely to recur, are depressing, often lead to melancholia, and are of grave import. Vertigo of the labyrinthine type is evidence of progression (See Me- niere’s disease). It may prove to be a persistent and recurring symptom, or it may never return after one or two attacks. The hysterical attacks are likely to recur and lead to all kinds of fears (phobia) and, at times, imperative conceptions in neurasthenic, over- wrought and weakened tabetics. The neurasthenic and hysterical element may predominate during any of the stages of tabes and influences the general condition unfavorably. Social Status.—The social status of the patient proves an enormous factor in the prognosis of tabes dorsalis. Poverty, with all of its baneful results, robs the patient of comforts including the necessary scientific nursing, which prevents septic infection in the terminal stages of the disease. The psychic element is a paramount factor: the depression of the para- lytic who lives in want exerts an unfavorable influence. Under these con- ditions there is often rapid progression, exhaustion, marasmus; and in same cases cerebral hemorrhage ends the scene. Septic conditions, including ascending infection from the bladder (pyelonephritis), are responsible for the death of some paralytics—espe- cially among those who are neglected. Cystitis is one of the leading causes of sepsis. Neglected cases of those markedly emaciated often develop bed-sores (decubitus) ; once formed they heal with great difficulty, and may also cause septic infection. Sepsis.—Sepsis may be either acute or chronic. Chronic cases are associated with progressive loss of weight, increasing anemia, albuminuria, irregular fever, and persistently rapid pulse. These symptoms may per- sist during a number of weeks or months, during which the patient gradu- ally wears out and usually dies in coma, with all of the symptoms of pro- found toxemia. The acute cases of sepsis are at times foudroyant, or they may lead to 60 SPECIFIC INFECTIOUS DISEASES death after from 7 to 21 days, including delirium and most of the symp- toms of the chronic type. Hemorrhagic Conditions.—Purpura has been a terminal condition in some of our cases in which the patient gradually failed, was exhausted, and had been bedridden during varying periods. The forecast is always unfavorable when hemorrhagic symptoms, in- creasing marasmus, and bladder symptoms are associated in the ataxic or paralytic stages. Cerebral hemorrhage in patients with arteriosclerosis is a frequent cause of death; some remain hemiplegic during varying periods. The trophic changes including more particularly perforating ulcer and spontaneous fracture do not lead to death directly, but they often aggravate existing conditions: at times the ulcer causes septic infection; with frac- ture of the femur bed-sores form which, with persistent cystitis, are compli- cated with sepsis and death. Duration.—It is difficult in any case to foretell its duration. Ho fig- ures which we can give are absolutely reliable nor are they of great impor- tance. There are cases which cover 3 and 4 decades, others in which death follows after between 10 and 20 years, and still other cases in which the disease, because of complications, ends early. Each case demands separate consideration. Tabetics often reach old age. v. Malaise’s records prove that 51 per cent of his cases died after 60, and 83.3 per cent lived to reach 50 and longer. General Conclusions.—The degeneration which characterizes tabes provokes changes which do not permit the conclusion, with our present knowledge, that they can he overcome; in other words tabes dorsalis which presents symptoms sufficient to make its recognition positive, does not, in spite of statistics to the contrary, lead to restitutio ad integrum. Symp- toms may improve or during periods be entirely absent, hut the ravages of the disease continue. Chronicity is the rule. Long periods of latency are to be expected, ard often the relief of many sensory symptoms by modern treatment is posi- tively attainable; but persistent and almost continuous attention to the individual case, with scientific nursing, is necessary to hold the patient in the bettered condition. The outlook so far as the life of the patient is concerned is not so bad as is generally supposed by the lay world—a fact which we have ac- cented in this chapter. Statistics are materially influenced by many factors; foremost among these are heredity, diathesis, social status, occupation, and habits. The wide difference in the conclusions of different observers is demonstrated by the study of the following data taken from leading French and German sources. PROTOZOAN INFECTIONS 61 Pellugaud and Faure, Belugon and Faure, quoted by Oppenheim, report:— Tabes arrested in 19 per cent of cases Tabes with remissions in 40 “ “ “ “ Benign in 59 “ “ “ “ Tabes progressive in 30 “ “ “ “ Tabes acute in 6 “ “ “ “ Tabes grave in 36 “ “ “ “ Tabes regressive in 5 “ “ “ “ Tabes cured in 5 “ “ “ “ v. Malaise on the other hand is more conservative and does not speak of cured tabes. He reports of 76 cases: 2 cases without symptoms. 26 “ returned to work. 30 “ show steady progression. 18 “ rapid progression with bad general condition from the beginning. Syphilis of the spinal cord offers a less favorable prognosis than does cerebral syphilis. The latter is unquestionably always recognized in its incipiency, the former only after a period of progression. Taboparesis Taboparesis is a combination of disseminated changes in the spinal cord, brain, and peripheral nerves in which there has been, as a rule, a con- siderable period of tabes dorsalis with Argyll-Robertson pupil, character- istic behavior of the reflexes, ataxia in some cases, and lightning pains, to which the mental symptoms of paresis are added. Reverse conditions may prevail, and the symptoms of tabes are added to those of paresis; in rare cases the symptoms of both tabes and paresis are present together from the beginning. Optic atrophy with tabetic symptoms and even insignificant evidences of mental disease with the characteristic reactions of the lumbar fluid, including positive Wassermann reaction, with or without positive reaction of the blood serum, is strongly suggestive of approaching taboparesis. We know of no case in our practice in which any form of treatment has favorably influenced the disease. Whether the salvarsan-mercury treat- ment will ultimately prove of value in those cases in which the diagnosis can be made in the incipient stage of the disease, cannot be decided at the 62 SPECIFIC INFECTIOUS DISEASES present time. Whether such treatment will prevent this late manifestation of tertiary syphilis entirely, cannot be determined until years of observa- tion have lapsed. General Paresis {Dementia paralytica, Progressive paresis) General paresis is always due to syphilitic infection: the presence in paretics of the Treponema in the brain, the positive Wassermann reaction of the blood and withdrawn cerebrospinal fluid, as well as the other char- acteristics—chemical and cellular—of the fluid, positively prove the patho- genesis of the disease. Five per cent of syphilitics develop paresis. While many paretics were insufficiently treated during the initial and secondary stage of the pri- mary infection, it may happen that thoroughly treated syphilis leads to paresis. Oppenheim and L. Meyer report cases which developed after the salvarsan-iodin and mercury treatment. The disease is most frequent between the thirtieth and fortieth year; rare before the twentieth and after the sixtieth; as tabes, it is also more fre- quent in men than in women. In over 20 per cent of paretics, symptoms of tabes dorsalis preceded the onset of mental deterioration. The same factors which predispose syphilitics to tabes are largely re- sponsible for the development of paresis. I am impressed by the fre- quency of paresis in syphilitics who are subjected to long mental strain and overwork, and lean strongly to the theory of Edinger, to which refer ence was also made in considering tabes. The average duration between the initial specific infection and the development of paresis is between 10 and 25 years. It does not matter what the psychic symptoms are, whether the disease is recognized early or late, what the behavior of the reflexes, however char- acteristic the pupillary reactions, what the changes in speech or penman- ship, whether tremor is present or not, whether paralytic conditions are complete or incomplete—we are absolutely powerless in positively diagnos- ticated cases to influence the disease itself favorably by any known treat- ment, though periods of apparent improvement and remission are not un- common. The foregoing statement is based on my own experience with the dis- ease, with the full knowledge of the cases of improvement and cure which have been reported by able authorities. Among these I refer to Dana and to the recently published statistics of Browning and Mackenzie and those cited by Oppenheim in considering the literature. Dana reported a number of recoveries and improvements in whom the diagnosis of paresis had been made. Browning and Mackenzie report 12 of 58 paretics improved, of which number 6 returned to their occupations. PROTOZOAN INFECTIONS 63 There are a number of cerebral lesions of specific origin which are not true paresis, but in which the symptoms of paresis are simulated. In such cases improvement or cure is possible, and almost all of the cases reported as cured paresis belong to this class. It is not uncommon for the spinal fluid of paretics to show a reduction of lymphocytes after salvarsan injections and some have reported improve- ment of symptoms (Millian and Levy-Valensi). Remissions and long periods of latency are noted, but the disease finally proves to be progressive. It is these periods of latency or remission, some- times surprisingly long, which delude the enthusiastic advocates of a good prognosis to believe that the process is stayed or cured. Jacobsohn says that “the possibility of a cure has a more theoretical than practical value, and in offering the prognosis it need not be taken into account.” “In spite of this fact, it is not wise for the physician to give an abso- lutely bad prognosis at once; the withholding of the prognosis is wise until all doubt of the diagnosis has been overcome, for every neurologist has met cases in which the progress of the case has proved the possibility of error, and nothing is so humiliating to the diagnostician as to have delivered a death sentence in a case in which it was not justified.” The Wassermann reaction of the blood is positive in 100 per cent of paresis. The withdrawal of the cerebrospinal fluid shows 1. Increased pressure in the subarachnoid space; besides this 2. Globulin reaction (Phase 1, Nonne) positive in from 95 to 100 per cent 3. Lymphocytosis in 95 per cent 4. Wassermann reaction positive by the original method in 85 to 90 per cent, by the newer method in 100 per cent 5. The total albumin content is increased, but varies materially without known cause. The average (Plaut, etc.) is 0.045 per cent, and is greatest in cases which have existed about 1 year. The cellular elements are greatest in cases which are in their second or third year, and may be reduced by salvarsan (Plaut). The stage of the disease does not influence the Wassermann reaction of the fluid. The weaker reactions (Wassermann) are found in cases which progress slowly or remain stationary during long periods. Negative reactions are found during stationary periods and remissions. In a few cases salvarsan weakens the Wassermann reaction of the spinal fluid; in rare cases it may become negative. Trophic changes may develop during the course of paresis, including perforating ulcer, spontaneous fracture, arthropathies and gangrene, and an atrophic condition of the nails; these conditions are but little influenced by treatment. The majority of our cases have died of cerebral hemorrhage after the usual apoplectic symptoms, which continue two or three days. 64 SPECIFIC INFECTIOUS DISEASES Paretics may become hemiplegic or confirmed epileptics with distinct aurse—grand or petit mat. Transitory paralyses and aphasia characterize some of the cases in the last stage. These paralyses may disappear promptly or continue one or two days. Paretics with advancing paralysis or ataxia, finally become bed- ridden and helpless. They develop bed-sores, cystitis, and sepsis, unless well nursed. Death with septic symptoms in these cases is the rule with marked inanition. Dementia is prominent before the end of the second or third year in the average case, disturbance of speech is fully developed, the facies charac- teristic, locomotion usually much disturbed, and the sphincters are para- lyzed (incontinence of urine and feces). Death in the second or third year is the rule; acute cases may run a short course, ending within a few months—most of these are hemorrhagic. The cases which live during many years are usually women with marked dementia, senile patients, or taboparetics. Intercurrent infection has been followed by the remission of symptoms. Steiner reports erysipelas, and Foerster typhoid fever, Oppenheim pneu- monia and profuse suppuration closely related to remissions. Intercurrent pneumonia is often a cause of death in paretics with bul- bar symptoms (aspiration pneumonia). Salvarsan has been used long enough to prove that it does not cure nor materially influence paresis. The only hope lies in the possible prophylac- tic efficiency of the drug, by its intensive use during the early stages of syphilis. Ehrlich and his disciples have an abiding faith in the possibilities of prophylaxis from salvarsan; the reported development of paresis after its use by Oppenheim and L. Meyer is discouraging. Time and persistence will ultimately decide the question. Collins has recently placed himself on record as follows: “No matter how vigorous or drastic the antisyphilitic treatment, no one has ever been able to say that a case of tabes or general paresis has been cured by it; but, in making this “susceptibility to therapy” a distinguishing feature between the two classes of diseases (the syphilitic and so-called we have often lost sight of the fact that the former is a disease of the supporting or interstitial tissue and the latter of the paren- chyma, that is, of the nerve elements of the central nervous system. The parenchymatous cells have no more, and indeed no less, capacity of re- generation than the parenchymatous cells of any other organ of the body. Then, so far as we know, there is no substitution of function of the cells of the central nervous system. We are not in a position to say that if one cell in the central nervous system be destroyed, its function can be taken up by an adjacent cell.” “Since the introduction of salvarsan, and its utilization in the treat- PROTOZOAN INFECTIONS 65 ment of syphilis, there has been a great amount of reliable evidence—some of which I have furnished—tending to show that the parasyphilitic diseases can at least be brought to a cessation of activity by the appropriate use of this agency. It can no longer, therefore, be maintained that the so-called parasyphilitic diseases progress despite every treatment.” Juvenile Paresis.—Juvenile paresis is due to congenital syphilis and is more frequent in girls than boys. Rondonis and Strausslers have considered the developmental anomalies in cases of juvenile paresis, and Strausslers found these most prominent in the cerebellum. Strausslers in his work, claims that hereditary syphilis may cause paresis after the thirtieth year. Salvarsan improves the general condition of juvenile paretics; the Was- sermann reaction becomes negative, but soon returns to the positive phase; metabolism seems to be improved. The mental state is not changed. The reactions of the blood and cerebrospinal fluid of juvenile paretics run parallel with those of the adult. The prognosis is unfavorable. 2. Congenital Syphilis Heredity in Syphilis.—Our views with regard to the heredity and mode of transmission of syphilis from parent to offspring have been ma- terially influenced by the newer methods of diagnosis. It may now be assumed with certainty that the disease is conveyed by the mother to the child through the placenta (maternal transmission), and whether the mother presents symptoms of syphilis or not, she offers a posi- tive Wassermann reaction. This disproves the contention of Sir Jonathan Hutchinson that “the father may infect his offspring (the mother never having suffered), and that this is by far the most frequent mode by which the disease is transmitted.” In the mother the disease may he latent—she may never develop active symptoms—hut she is nevertheless syphilitic. The mothers of congenitally syphilitic children are immune to syphilis; they cannot be infected through the syphilitic child nor in any other way (Colles-Baume law)—which is another proof of maternal and latent infec- tion; further the same syphilitic child can infect its nurse through the nipple, etc. For prognostic purposes it may be held that a father who has had syphilis need have but little fear for the safety of his children, so long as his wife shows a negative Wassermann reaction (Bayly). The rigorous treatment of the mother during pregnancy may result in the birth of an apparently healthy child. Most of these children give positive Wassermann reactions and are therefore latent syphilitics. Such children are as a rule immune to syphilitic infection {Profeta Law). Unquestionably a large number of these cases which with a positive Wassermann reaction are to he considered latent syphilitics, account for the late manifestations of the 66 SPECIFIC INFECTIOUS DISEASES disease in the subjects of congenital lues which offer unfavorable forecasts (syphilis hereditaria tarda). Not all children of a syphilitic mother inherit syphilis. There are cases recorded in which with twins one was syphilitic, the other escaped infection. Bayly quotes the results of Wassermann reactions of congenital syphilis as follows:— In 20 cases he found 95 per cent positive. Noguchi and Kaplan in 37 cases found 95 per cent positive. Hoehne found 88 per cent positive. Marcus in 29 cases found 90 per cent positive. Boas in 72 cases found 100 per cent positive. A parent with tertiary syphilis may show active symptoms and objec- tive signs, and yet the children may be non-syphilitic. Hutchinson says: “a child may wholly escape under circumstances apparently full of risk.” The severity of the infection in the child is not in proportion to the severity of the symptoms in the parent. Mild symptoms or latency in the parent are often found with malignancy of infection in the child. The subject of congenital syphilis who lives beyond the dangers of the first few years of life offers a good prognosis so far as life, is concerned; but he is under par as a rule until he has gained his full growth and often after he is handicapped in the race, and to the expert presents stigmata which brand him. Characteristic Manifestations.—The syphilitic may come into the world with grave lesions of one or more vital organs: kidney, spleen, liver, pancreas, thymus, lung, etc. Specific change in one or more of these may cause death in utero. Early pemphigus syphiliticus is usually fatal; this may be present at birth, or develop within a few days. Changes in the nails and skin are characteristic of congenital syph- ilis (onychia syphilitica.) Coryza, persistent snuffles, with crusting in the nose and degenera- tive changes in the nasal septum, are among the earmarks of congenital syphilis and may persist during early childhood. Growth, nutrition and mental progress are materially influenced by congenital syphilis. “Fournier’s infantilism” characterizes many of these unfortunates. We have already considered the changes in the liver and spleen, to which we refer the reader. Most of these complications lead to early death. Nose and Ears.—Extension of disease through the nose to the ears is frequent and damaging, often leading to deafness. Enlargement of lymphatics, persisting during long periods with anemia and malnutrition, rob the child of resistance and make him ready to yield to acute infection. Anemia of Congenital Syphilis.—The anemia of congenital syph- ilis is of three types: (1) chloranemia with leukocytosis (2) pernicious PROTOZOAN INFECTIONS 67 type, (3) leukemic type (Bayly). Most forms resemble the usual secon- dary anemias of infancy and make satisfactory recoveries. Lymphocytosis is characteristic of all forms of syphilitic as well as the non-syphilitic ane- mias of early life. The leukemic type offers the most serious prognosis. There are many nucleated reds, and in some cases the combined count of lymphocytes may be high, reaching 50,000 to 60,000 (lymphocytes, mye- locytes, and polymorphonuclear leukocytes). Pneumonia is particularly fatal in the subjects of hereditary syphilis during the early years of life. Early and late purpura may be of specific origin. The hemorrhage of the newborn when specific is usually fatal (syphilis hemorrhagica neona- torum■). Hutchinsonian teeth (notched, malformed, undersized) are char- acteristic of congenital syphilis. We have never seen these teeth (per- manent teeth) in subjects who did not present other positive stigmata of hereditary lues. Eye lesions' may be either early or late. Keratitis (phlyctenular and interstitial) is frequent and often rebellious to treatment with great ten- dency to relapse. In many of these forms of corneal inflammation there are permanent though insignificant opacities of the cornea. Changes in the bones of hereditary luetics are frequent; during fetal life the epiphyses may be involved and loosened with cartilaginous prolif- eration. Most of these are stillborn (osteochondritis syphilitica). Hereditary lues is very likely to interfere with the growth of bone tissue and retards the closure of the fontanelles, or occasionally it happens that there is an abnormal overgrowth of bone which causes premature closure. Such skulls are often congenitally malformed. Most congenital hydrocephalus is of specific origin and offers an unfavorable prognosis. When these children live, as they sometimes do for several years, their development is exceedingly slow and their mental condition is always defective. Congenital lues predisposes to rachitis. With hereditary syphilis arteriosclerosis or arteritis is frequent during early life, and may lead to the same far-reaching organic changes which accompany non-specific arteritis. These luetics are constantly on the edge of a precipice: they rarely live beyond the thirtieth year. When syphilitic babes develop intestinal lesions they offer but little resistance and rarely recover. Destructive disease op the skin, nose and the soft palate is rarely found in cases which receive appropriate and early treatment. ISTervous System.—The ravages of hereditary syphilis as they are found in the nervous system often lead to irreparable damage. Paralysis, convulsions, epilepsy, blindness, deafness, idiocy are among the dreadful sequelae of the infection. Fournier includes amblyopia, myopia, nystag- 68 SPECIFIC INFECTIOUS DISEASES mus, asymmetry of the face, congenital heart defects, harelip, spina bifida hydramnion hypospadias, abnormalities of the hands and feet. Congenital syphilis is uunquestionably responsible for a large number of so-called neuropathies. General paresis may develop in congenital syphilitics; also tabes and multiple sclerosis. There is scarcely an organ which may not show the ravages of heredi- tary syphilis; on the other hand it is encouraging to note that the perma- nent lesions of syphilis are in the majority of cases prevented by timely treatment. Syphilis can be transmitted to the third generation. This is the con- census of expert opinion, though there are able syphilographers who deny the possibility. Groups of such cases have been reported in medical litera- ture by reliable observers (Fournier). England’s greatest authority, the late Sir Jonathan Hutchinson, remained a strong opponent to the views of Fournier. Syphilis and Marriage The consideration of this subject requires but little time or space, if we divorce ourselves from sentiment and base our recommendations on scien- tific and clinical experience. I may be criticized for this arbitrary rule from which I claim there should be no exception, but in practice it offers the best prognosis. My rule is as follows: No syphilitic should marry unless he has been radically treated; has shown repeated negative Wassermann reactions during at least two years, and has been without mucous patches for at least twelve months. A' single negative Wassermann reaction after treatment is of no value in the matter of prognosis in connection with marriage, if considered apart from other features of the case, and will prove misleading and disastrous. Dreyer reports cases in which the Wassermann was negative for 3 or more years, with return to a positive phase and activity of the disease. Syphilis and Life Insurance No applicant who has had syphilis deserves to be considered a first- class risk. The dangers of late manifestations, metasyphilitic and cardio- vascular complications must be taken into account before giving a rating. In considering the problems connected with life insurance and syphil- itic subjects, it is well to remember that some luetics remain free from symptoms during many years, who suddenly develop active syphilis in its most malignant form. The average syphilitic will not live to his full expectancy. Mortuary records show that diseases of the circulatory organs are the cause of death in over 50 per cent of syphilitics. The involvement of the nervous system is among the frequent causes of death with which life insurance companies must reckon. PROTOZOAN INFECTIONS 69 Placing syphilitics in a class by themselves it is safe to conclude that with evidence of prolonged treatment, the period of freedom from symp- toms and the negative Wasserniann suggested in the rule given above, which justifies the marriage of the syphilitic subject, the risk may, with such added rates as are made by most companies, be accepted. The Fate of Syphilitics and their Children Kaufman has followed a large material which made it possible to offer valuable data concerning the fate of syphilitic couples and their children: It has been found that in 15 to 20 per cent the marriages of syphilitic couples are sterile; 32.9 to 40 per cent of tabetic wives are sterile. Following 10 couples, all syphilitic, and their children, the following facts were established by Kaufman-Wolf:— 5 of the 10 men died, the causes of death and their ages were: 1. Locomotor ataxia, aortic aneurysm; age 52 2. Pulmonary tuberculosis with heart lesion; age 36 3. Pneumonia with delirium tremens, arteriosclerosis and coronary disease; age 45 4. Insane (suicide) ; age 36^ 5. Paresis; age 57. Conjugal Nervous Lesions.—In 4 couples the following conditions were found: Husband Wife 1. Paresis Locomotor ataxia 2. Paresis Delirium tremens 3. Psychosis Insane (psychosis) (manic depressive) 4. Paresis Paresis In syphilitics the duration of married life was found between 6 and 25 years. Among 9 syphilitic couples there were 66 pregnancies; these included 33 abortions or stillbirths and 33 living children. Of the 33 living children, 20 died—14 during the first years of life: 3 suicided (12-|, 20, 28 years respectively), two were epileptics (both died in public institutions), and one aged 40 died as the result of an intestinal lesion requiring a surgical operation. Thirteen are still living of whom only 2 are normal; all the others are mentally and morally defective. 4 children of the second generation are normal. All statistics 'prove the frightful mortality among the offspring of syphilitics during the first seven years of life. Fournier reports 18 syphilitic families with 161 pregnancies, of which 137 were stillbirths—85 per cent. Hyde reports 1,121 syphilitic births, with 916 deaths during the first 70 SPECIFIC INFECTIOUS DISEASES year of life. The Moscow Orphan Asylum presents 70 per cent of deaths during the first year of life, among 2,088 syphilitic children. Koplik reports 66,537 hirtlis, with 2,732 deaths from all diseases during the first four weeks of life in the Borough of Manhattan, of which but 47 are cred- ited to syphilis. Haskell gives the results of his observations as to syphilitic infection in the conjugal mate'and offspring in fifty-five cases of general paralysis in which the presence of syphilitic infection in the mate was tested, and in eighty-six cases of general paralysis in which there was a definite anam- nesis concerning pregnancies and offspring. Ilis conclusions are as fol- lows : “The large number of 38.18 per cent of conjugal mates of paretic patients is shown to be infected with syphilis. In most of these mates the condition courses unrecognized as lues latens. “A pitifully small number of them ever receive treatment. “The proportion of these infected mates who later develop paresis appears to be higher than those who receive their infection from non-ineta- syphiiitic sources. “The number of completely sterile marriages in syphilitic families in which one individual later develops paresis is abnormally high, constitut- ing 32.5 per cent. This percentage is higher when it is the female mate that later becomes a paretic. “The number of marriages in which repeated pregnancies result only in abortions is likewise abnormally high, constituting in our series 3 2.7 per cent. “Of our series of eighty-six marriages 45.3 per cent were absolutely childless. “Among 167 pregnancies there were forty-two abortions, miscarriages and stillbirths. “Among 123 living-born children twenty had already died before their eleventh year. “The number of living children per family is abnormally small. “A large number, in some investigations reaching as high as 25 per cent, of these children are actively syphilitic. “An equally large additional number show signs of degenerative physi- cal conformation and psychopathic tendencies without a positive Wasser- mann reaction. “Much of all this is preventable.” Carriers of Treponema Pallidum There are “carriers” of spirochetes who never themselves know that they are syphilitic; thus a man may acquire syphilis during his first mar- riage or during illicit intercourse and infect his second wife or others, PROTOZOAN INFECTIONS 71 without having himself ever had any of the subjective manifestations of the disease.

Malaria (Ague-Wechselfieber, Paludism, Intermittent Fever, Estivo- autumnal Fever) Malaria is a specific infectious disease of protozoan origin, due to the entrance into the blood of one of the Ilemosporidia or ITemocytozoa of Laveran attacking the red of man, in which the parasite undergoes a definite cycle of development. Its sexual phases take place in the mosquito—the Genus Anopheles—which has become infected by biting sufferers whose blood held the gametes of the Protozoa of malaria (.Plasmodium malaria). For our purpose we will consider the features of the disease as pre- sented by: 1. Intermittent malarial fever. (a) Quotidian type (double infection with the tertian parasite). (b) Tertian type (Plasmodium vivax). (c) Quartan type (Plasmodium malaria?). (d) Irregular intermittent fever. 2. Eemittent malarial fever (always due to the Plasmodium precox or falciparum). (a) Estivo-autumnal fever (or continued malarial fever). (b) Pernicious malarial disease. I. Cerebral. II. Algid (or gastro-intestinal). III. Pulmonary. (c) Black water disease (or hemorrhagic malarial fever). 3. Chronic malaria (malarial cachexia). 4. Mixed types of malarial fever. 5. Malarial neuralgia. The general statement is justified that the lesions of; malaria are due to the destruction of blood-corpuscles by the individual parasites causing the special type of the disease, and the toxin produced when the organism divides (segmentation). The pigmentation in the various organs of the body is in proportion PROTOZOAN INFECTIONS 73 to the chronicity of the disease; is due to the plugging of capillaries by the organisms within them. The spleen is uniformly enlarged in all malarious diseases; its size and the organic changes are proportionate to the chronicity of the disease and the neglect of proper treatment. The same may be said of the liver and of the blood. The malignancy of all malarial disease depends upon the number of Protozoa and their resistance, the lack of strength and the endurance of the patient. As a rule, as will be emphasized in the consid- eration of the separate forms of the disease, even these factors are over- come in most cases by specific treatment. Whether the unqualified state- ment made by Osier: “Xo infection—except perhaps tuberculosis—com- pares with it (malaria) in the extent of its distribution or its importance as a killing and disabling disease” is still justified, is open to argument in the light of recent experiences. Immunity is by no means granted by one or more attacks of malarial infection. It has been shown in the tropics, however, that adults who suffered early in life have at times shown greater immunity than others. 2. Intermittent Malarial Fever The quotidian type is more weakening than the tertian. When double (two cycles within 24 hours) it is depressing, may be associated with febrile albuminuria, but yields promptly to treatment. The larger number of cases are tertian—the cycle of symptoms recur- ring every other day at the same hour—observing the 'periodicity which is a family resemblance of all forms of. malaria. In an experience of over thirty-five years I have never known of a death due directly to inter- mittent malarial disease treated by quinin, and the deaths reported by others are so few that they offer only a negligible factor. (a) Quotidian Type (c) Quartan Type The quartan type is exceedingly rare (17 cases in 1613) (Thayer). Its prognosis is favorable; it is however more stubborn than the other forms of intermittent fever. (d) Irregular Intermittent Fever The merging of a tertian into a quotidian, or vice versa, or the development of double tertian from single tertian does not change the favorable prognosis. When the fever is “postponed,” i. e., the cycle begins later than in the previous attack, it is evidence of improvement, easy and early control. When the fever “anticipates,” it may be inter- 74 SPECIFIC INFECTIOUS DISEASES preted as meaning that conditions are less favorable and demand active treatment, which will usually prove efficacious. Relapses will follow all forms of intermittent malarial disease unless rigorously treated or the patient is removed from the source of infection. Spontaneous recovery may follow change of abode. 2, Remittent Malarial Fever (a) Aestivo-autumnal Fever (Continued Malarial Fever) This type of infection (Plasmodium falciparum) is rarer than the intermittent, and more resistant to specific treatment. The disease is less likely to observe the “family tendencies” in periodicity, is therefore given to irregularity, is likely to develop continuous fever, resembling typhoid—unjustly called by some typhomalarial fever—and if neglected or improperly treated, pernicious symptoms may prove threatening and serious. The paroxysms of the disease are longer than are those of the inter- mittent fevers In cases which are benign, there is, as a rule, a decided drop of temperature during the early morning hours. Patients may present with marked evidence of invasion of the nervous system, the typhoid condition becomes puzzling, the blood examination clinches the diagnosis and the prognosis at the same time. Unless the pernicious type of the disease develops, the prognosis continues good. The Estivo-autumnal infection may be complicated by the tertian or quotidian fever, both as a rule will yield to treatment, though the period of convalescence may be prolonged and anemia becomes striking. So- called “dumb chills” are among the more serious manifestations of the estivo-autumnal type of the disease. In the more severe types—those with pernicious tendencies—the nervous system is invaded, delirium— muttering or wild—is not uncommon. An average paroxsysm is between 20 and 24 hours. In those cases where mixed infection with two Pro- tozoa modifies the temperature curve, there may be considerable difficulty in deciding upon the nature of the infection and typhoid may be strongly suspected. The prognosis should be guarded accordingly until treatment and blood examination clear the horizon. (b) Pernicious Malarial Disease This is always serious. As a rule the cases have become chronic; there are organic changes in the spleen and in the liver, the blood has been disorganized, and the patient has been robbed of resistance. In some cases there has been nephritis, occasionally hemorrhagic. Pernicious malarial complications offer the gravest of all prognoses PROTOZOAN INFECTIONS 75 in malarial infections. The symptoms are either, (I) cerebral, (II) gas- trointestinal (algid), or (III) pulmonary. Cerebral Pernicious Malaria.—Cerebral pernicious disease is always serious. Coma Type.—In some cases there is a sudden overwhelming of the nervous system, with final merging into deep coma after a period of exaltation, possibly delirium and few gastric symptoms. In the severe cases there may be irregular labored breathing (Cheyne-StoTces) or it is stertorous There is hyperpyrexia (106°-108° F.), which with rapid feeble pulse tells of the serious condition of the patient and clouds the outcome. In some of these cases improvement may lead to prompt recovery; in others it is soon followed by a repetition or deepening of symptoms, and death. Second paroxysms are almost always fatal. Quaife has called attention to cases of this type which have remained in coma during long periods, which finally recovered. One of Quaife’s cases (aet. 18) was unconscious during 48 hours—in deep coma—but finally made a full recovery. Cases of pernicious anemia of the cerebral type may suddenly develop active mania, convulsions, symptoms of active or passive cerebral congestion—usually the former—resembling meningitis; there may be paralysis (bulbar, aphasia, hemiplegia) with eye symptoms, amaurosis, cerebellar symptoms, or even tetanoid symptoms. An early prognosis in either of these pernicious types of cerebral pernicious invasion is impos- sible ; it will always require three days of active treatment to reach safe conclusions. In both these types of pernicious fever the end of the first period does not justify a positive forecast for there may be a repetition of all symptoms, with increased severity, and prompt death. In the majority of cases recovery follows the first paroxysm. Algid (or Gastro-Intestinal) Pernicious Malaria.—In this type of per- nicious disease the patient has many of the symptoms and the appearance of the cold or algid stage of Asiatic cholera; the condition is serious, and the outlook is often bad. The pulse in the grave forms is small, rapid, without character; the stools numerous, watery and large. The extremi- ties and the entire body are cold. Cyanosis with the symptoms mentioned makes the picture of the most severe cases complete. Death as a rule is not long postponed. In some of the suddenly depleting forms of algid disease death may follow in from 2 to 4 hours. A bilious type is occasionally met, in which vomiting, jaundice and other gastro-intestinal symptoms are in the ascendency. Many of these recover. Pulmonary Pernicious Malaria.—The pulmonary or pneumonic type of pernicious malaria is characterized by symptoms of edema, congestion, or pneumonic infiltration. Heart iveakness may seriously influence the outcome. In some, death follows promptly from edema of the lungs; in 76 SPECIFIC INFECTIOUS DISEASES other cases prompt treatment—rigorous and persistent—leads to happy recoveries. In all types of the pernicious disease the prognosis is grave in direct proportion to the number of Protozoa in the blood in the interval follow- ing the attacks; though, to quote from Thayer: “the disappearance of the parasites from the blood under treatment of itself” “does not justify a favorable prognosis, for, despite this, the pernicious par- oxysm may continue to a fatal termination.” Purpuric complications (purpura hemorrhagica) with any form of pernicious malaria is evidence of malignancy. (c) Black Water Disease (Hemorrhagic Malarial Fever) This usually occurs in East and West Africa, the Southern States of America, and in Central America. Some have held that large doses of quinin given to malarial subjects have been responsible for the symp- tom complex. Those who have had most experience with the disease agree that this is not true, that as Stephens’ investigation shows in a study of 95 cases, Protozoa were present in 95.6 per cent of the cases before the onset of hemorrhagic symptoms, and in 61.9 per cent, on the day of the appearance of the disease. Thayer agrees that malarial hemoglobinuria, as found in the Southern States, is not due to quinin. The most reliable data dealing with prognosis are offered by the expe- riences of the employes along the Panama Canal zone. These prove that quinin as ordinarily administered is not efficacious but its intramuscular injection has proved specific in its effect in almost all cases of blackwater disease. The mortality of blackwater fever is between 5 and 10 per cent. Complete anuria may persist during long period (48 to 60 hours), and yet recovery follow. 3. Chronic Malarial Cachexia ISTo thoroughly treated case of malaria develops the characteristic chronic cachexia. Whenever it is found it is evidence of neglect or repeated infection. The factors which influence prognosis with this condition are: the reduced state of the patient, the marked anemia, the condition of the spleen, associated kidney and liver complications, dropsies with circula- tory insufficiency. The anemia has the ear marks of the secondary type; color index is reduced with erythrocytes low, and leukocytes are also below the normal count. There is an increase of mononuclears—lymphocytes—with nucle- ated red blood corpuscles. The severity, or depth of these changes as shown by microscopic examination, are potent in giving a forecast. It must be PROTOZOAN INFECTIONS 77 remembered that in the presence of grave anemia with changes in spleen and other organs, the patient in a favorable environment with specific treatment may gradually lift himself back to health. Cases of malarial cachexia in which the blood picture of pernicious anemia developed have been found to lead to death within a short time. In these cases the meg- aloblastic evidences of the disease with a white count approaching leuko- penia, a large percentage of small mononuclear cells, and no nucleated red corpuscles were found (aplastic anemia) (Thayer, 1. c.; Bignami and Diosini; Ewing). Purpuric eruptions and hemorrhages are present with the more serious cachexias, but do not make the prognosis! absolutely bad if the patient can be controlled. The evidences of dropsy begin to dis- appear as the anemia is relieved and circulatory balance is restored. The chronic changes in the spleen, enormous “ague cake” and liver enlargement far advanced, may yield to treatment; and restoration to health with these complications is not unusual. In the majority of chronic malarial cachexias the patient holds his fate in his own hands, his recovery will depend entirely on his ability and willingness to remove himself from baneful surroundings and the relig- ious following of rational medical treatment. 4. Mixed Types of Malarial Fever Reference has been made to the mixed types of the disease in the preceding pages—the merging of one type into another—the infection of the patient with the Protozoa of estivo-autumnal disease and one or more of the Ilemosporidia of the intermittent fevers. In all, the prognosis is good. Recovery may be delayed and convalescence interrupted by the development of the fresh outbreak, as a rule of tertian or quotidian fever. 5. Malarial Neuralgia These types of neuralgia frequently met in the United States with or without febrile movements, as a rule observing characteristic period- icity, unquestionably of protozoan origin, yield very promptly to treat- ment. They recover with lowered resistance and evidences of anemia. There is slight enlargement of the spleen, which disappears with recovery. Complications Bronchitis, usually benign, is not infrequent and does not interfere with recovery. Pneumonia is not rare; its prognosis depends on many fac- tors which will be considered in connection with pneumococcus infection. Dysentery is a frequent complication of malaria, usually of the amebic type, oftener in the tropics than in the United States, though epidemics of dysentery in Central New York have been found with widespread in- 78 SPECIFIC INFECTIOUS DISEASES termittent fever. In 1879 and 1880 as the Hew York Central Railroad built its freight tracks around the city of Syracuse, along the marsh, types of both diseases were found which yielded to antimalarial treat- ment only. Nephritis.—Both Thayer and B. Rosenstein call attention to the frequency of this complication. Thayer reports 1.7 per cent of 1832 cases examined at the Johns Hopkins Hospital with acute nephritis. The complication is most frequent in the estivo-autumnal form. Most of these recovered. My experience runs parallel with this. I have traced several cases of chronic nephritis to malarial infection. The other complications, including orchitis, gastrointestinal disturb- ances, end in recovery. Miscarriages are not infrequent, during some seasons in malaria-ridden districts these have been as high as 50 per cent in the infected pregnant women. The influence of large doses of quinin in producing miscarriage should not be ignored. Tuberculosis and malaria are frequently associated; the association of these infections is likely to influence the former unfavorably. The few anomalies of the nervous system traceable directly to ma- larial infection are as a rule favorably and promptly influenced. In no other infection can a prognosis be given with greater certainty in the overwhelming majority of cases, than in malaria; the therapeutic test—the prompt use of the specific—not only allows early and easy prog- nosis, but at the same time it clinches the diagnosis.

Amebic Dysentery-Amebiasis Acute Form Amebic dysentery is endemic in the tropics and is caused by the Entameba histolytica and the Entameba tetragena; it is more likely to cause secondary changes of grave nature, including metastatic abscesses— liver oftenest. There is greater tendency to chronicity; there is greater tendency, as already suggested, to multiple ulcerations undermining of PKOTOZOAN INFECTIONS 79 the mucosa (liquefaction) (Councilman and Lafleur), than with the bacillary disease. The graver types show marked constitutional disturb- ance during the first 2 or 3 days of symptoms. The tongue is dry; abdo- men tender, at times tympanitic; great tenesmus; rapid, small pulse; stools numerous and small, at first fecal, then bloody, foul-odored, at times with slough. The frequent stools with tenesmus and rectal prolapse add greatly to the pitiful condition of the patient and provoke exhaus- tion. Cessation of pain in the last stage of the disease is often a precursor of death; the irritability of the expulsive muscles becomes exhausted so that painful efforts cease and are impossible. The urine decreases in amount in these cases; is heavily laden with indican; albu- minous; with hyaline and granular casts. In the acute period almost complete suppression adds an element of danger. Cases with many of the above symptoms may continue during weeks and months, emaciating until they look like the reconcentrados seen during the Spanish War, and yet they may recover. In these grave cases there is some enlargement of the spleen and liver. The most severe, usually the fatal cases, are of the gangrenous type. These patients are apathetic, have the appearance of deep sepsis, as a rule remain conscious, while stools are involuntary; there may be perforation, and if they recover, misshapen and strictured tissues result. Heart weak- ness, after a long period in which emaciation and exhaustion are extreme, ends the scene in most cases. Chronic Amebic Dysentery There is a strong tendency to chronicity in the amebic form of the disease. Subacute cases often continue to cause a modified symptom com- plex during 4 to 5, or even 6 months after the subsidence of the more painful accompaniments of the first month. With chronic amebic dysen- tery there is chronic invalidism, marked neurasthenia, or in some cases melancholia, irritable rectum, frequent stools; the patients are unable to return to the normal level of health, and in this state they live along for many years unless some of the usual complications terminate life. Periods of improvement, alternation of diarrhea and constipation, en- courage these patients to believe that recovery is complete, only to be discouraged by a return to the subacute or chronic state. Complications Abscess of the liver is one of the most frequent and serious complica- tions of amebiasis. Abscess may not form for weeks or even months after the initial symptoms. In one case, in ISTew York State, the patient who had a severe amebic dysentery, developed the abscess 6 months after sup- posed recovery, and was operated 2 months after its development. The 80 SPECIFIC INFECTIOUS DISEASES symptoms which led to its recognition were chills—irregularly distrib- uted—fever and excessive sweating, with anemia and polymorphonuclear increase. Physical signs of limited enlargement of the liver were present. The abscess was single. Multiple abscesses of the liver are rare with amebic dysentery. Unless abscess is relieved by operative treatment—or as occasionally happens, perforation with protective adhesions prevents general peritonitis and escape of pus—death usually results directly as the result of the abscess; or perforation into the lung or pleura (empyema) prolongs the misery and usually causes death. Perforation into the peritoneal cavity with prompt peritonitis ends the scene in occasional cases. Brain and splenic abscesses may complicate suppurative hepatitis; in all, the prognosis is equally bad. Other complications which are occasional causes of sudden death are perforation of the intestine with secondary peritonitis, intestinal hemor- rhage, pyelothrombosis, and myocardial degeneration. The invasion of the nervous system includes the same complications as were mentioned in considering bacillary dysentery; myelitis is possibly more frequent with amebiasis. The outcome of these complications is the same in both forms of the disease. Joint complications offer the same symptoms and prognosis as with bacillary dysentery. It is difficult to give figures which are to be relied upon showing the approximate death rate to be expected in future epidemics of this form of the disease. Epidemics will be better controlled. The disease is always serious; its mortality varies enormously in dif- ferent countries with different epidemics, is necessarily influenced by com- plications and sequelae, as well as by the surroundings and resistance of the patient. Symptomatic Dysentery Dysenteric symptoms accompanying acute infections, typlioid fever, puerperal fever, diphtheria, malaria, scarlet fever, measles, and other diseases, always add an element of danger and receive consideration in the separate chapters dealing with the diseases mentioned.

Trypanosomiasis (,Sleeping Sickness) Trypanosomiasis is a chronic disease, due to protozoan infection, Try- panosoma gambiense, which is introduced into the body by the bite of a fly—Glossina palpalis—characterized by malaise, fever, increasing weak- ness, loss of flesh, apathy, and somnolence. The Protozoon has been repeatedly demonstrated in the blood of the infected, also in the cerebro- spinal fluid. The disease has existed in equatorial Africa; now prevails to an alarm- ing extent in Siberia, Congo, Uganda, Rhodesia, along the Niger River and upper Nile. The infected may live many years, while in occasional cases death results during the first 12 months. In occasional cases there may be long periods of latency, with simple invasion of lymphatic glands and slight fever of remittent character. These periods may continue from 6 to 12 months, and then follows the period of continuous symptoms with the characteristic apathetic and sleeping stage of the disease. In the severe types, involuntary discharge of stools and urine are unfavorable and presage early death. Drowsiness from which the patients are easily aroused, passing into coma or increasing slowly from day to day is unfavorable. When coma is deep, death promptly results. The hlood offers a few prognostic data. Suddenly arising cyanosis with polycythemia (6,200,000 per c. mm.) is promptly followed by death. Sudden increase of existing anemia, as shown by a fall to 2,000,000 or under, is unfavorable. The hlood in average cases shows secondary anemia. Just before death the leukocytic count shows marked polymor- phonuclear increase, with large relative increase of mononuclear lympho- cytes. Anemia varies in accordance with the severity of the infection; it is a constant factor; the average count of erythrocytes is between 3,000,000 and 3,500,000. The prognosis of trypanosomiasis has been considered by some to have been favorably influenced by the introduction of the newer arsenic prep- arations, atoxyl, arsenophenylglycin and salvarsan (Robert Koch and Ehrlich). It is doubtful whether the infected ever recover without the flooding of the blood with some one of the arsenic preparations, and the effect of these is still sub judice. No patient can be considered cured until it is established beyond peradventure by repeated blood examina- tions that trypanosomes have disappeared from the blood, and negative auto-agglutination as well as a negative inoculation of the suspected 82 SPECIFIC INFECTIOUS DISEASES blood into susceptible animals has been fully proved. It is held by Low, that the prognosis is always grave, and the disease almost invariably fatal. Reference Low. Sleeping sickness. In: Allbutt & Rolleston’s System of medicine, ii, part ii., 224. V. Relapsing Fever (.Febris recurrens—Relapsing Typhus) Relapsing fever is due to infection with the Spirillum of Obermeier (1873) ; is sudden in its onset, the fever continuing during about one week, followed by an almost equal period of remission, with a renewal of the original syjnptoms. The first relapse is usually 1 or 2 days shorter than was the first attack; this may not always be the case. The average cases have hut two attacks, though exceptionally there may be as many as five or six. The disease is indigenous to Russia, Poland, some parts of Africa, and Egypt; is rare in America. High temperatures (105° to 106° F.) are not serious. The fever of the separate attacks ends by crisis and a fall of three degrees below normal, with profuse perspiration; sometimes considerable weakness follows: all of which need not alarm the attendant. Cases are reported in which the fall was as much as 10° F., ending favorably. The later relapses are shorter than those preceding, sometimes lasting only 1 or 2 days. During the period of convalescence slight elevation of temperature may occur without giving rise to symptoms (subjective), and these do. not interfere with recovery. They are either due to weak- ness or to abortive or rudimentary attacks. The prognosis of relapsing fever is good; most epidemics show a low mortality (4 per cent) (Murchison). Fatal cases are always due to complications—either pneumonia, asthenia, weak heart, pi'eexisting dis- ease, or alcoholism. Striimpell insists that some of the fatal cases are due to “wretched nursing.” Deep jaundice has complicated serious cases. The diagnosis can be easily confirmed by blood examination. I have seen but one case, which was persistent: there were six relapses. The patient was an active priest who had traveled over a considerable dis- tance; the focus of infection could not be traced. His convalescence was slow hut complete; his health has been better since the attack; there never has been a return of symptoms. Vickery (Striimpell) reports one case found in Boston. One attack does not produce immunity; cleanliness, destruction of the body louse and bedbugs—the carriers of the Spirillum—will prevent the spread of the disease.

Leishmaniasis (Tropical Splenomegalia, Indian Kala-azar, Infantile Kala-azar, Tropical Sore or TJlcer) The protozoa which belong to the Leishman group and which are re- sponsible for leishmaniasis are of three forms, each differing from the other in morphological and cultural characteristics, each developed in flagellate form. These include the (a) Protozoon of Leishman or Leisli- mania infantum, the cause of (1) infantile kala-azar; (b) the Protozoon described by Donovan as the cause of the type of the disease in India (2) Indian kala-azar and (c) Leishmania tropica of Homer Wright, now considered the cause of (3) tropical sore or ulcer. The Protozoon to which Leishman called attention (1900-1902) is found in the blood, spleen and bone marrow. Rogers subsequently con- firmed Leishman’s find and developed the offender in flagellate form. For over three decades the disease has been recognized as a cause of fatal epidemics in India, where adults are mainly affected, while the infantile type of kala-azar has claimed its victims along the shores of the Mediter- ranean Sea, in Greece, Turkey, Italy, Malta, Sicily, Portugal, Algiers, Tunis and Tripoli. In India it attacks all ages, while the disease as it is found along the coast of the Mediterranean Sea is often of the infantile type, though adult cases are not uncommon. There are cultural differ- ences (Leishman) in these two forms of kala-azar parasites; the infantile type is easily grown on the Xovy-McFeal culture medium, while the Protozoon of the Indian type of the disease is not easily cultured on this medium. The Indian parasite is readily cultured in splenic blood with citric acid; not so the infantile form (Leishntan-Hicolle). The inocula- tion of dogs and monkeys with the infantile parasite produces the dis- ease (Leishmania infantum), while the parasite Leishmania donovani (Indian Protozoon) gives negative results. With all forms of leishmaniasis, the parasites infest the spleen, liver, bone-marrow; at times the kidney, lung, pancreas; mesenteric glands and lymphatics generally. The prognosis of the infantile form of the disease is said by Leishman to be better than the adult form or the type prevalent in India. The recognition of the bedbug and the flea in India and along the Mediterranean as the carriers of the Protozoon has led to prophylactic measures in some quarters, but no benefit to the masses has as yet been reported. 84 SPECIFIC INFECTIOUS DISEASES The disease has raged in epidemic form in the colonies of India dur- ing many years and has at times claimed as high as 20 per cent of the entire population. The infection leads to secondary anemia, marked splenomegaly, emaciation, and atrophic changes in the internal organs (intestinal mucosa). The average duration is between 6 and 20 months. The period of in- cubation 20 to 30 days. Acute hemorrhagic conditions—profuse bleed- ing from mucous surfaces—nose, gums, stomach, intestines and meninges ■—may lead to sudden death. The blood condition is advanced, and pro- gressive cases show a reduction of the red corpuscles to 1,500,000, to 3,000,000, and the leukocytes to 700 to 1,000 per c. mm. with a marked polymorphonuclear decrease. Price placed the mortality of the epidemic in Assam at 73.6 per cent. Schilling contends that cases in which the fever becomes continuous offer the most unfavorable outlook. Rogers found that when the leukocytic count fell below 2,000 per c. mm. the rapid development of the disease was to be expected. Eo method of treatment used (including arsenophenylglycin and salvarsan) has proved of value to control the disease. Ricolle has seen but one case of the infantile disease recover.

Typhoid Fever {Enteric Fever, Typhus abdominalis) Typhoid fever is a general infection dne to the Bacillus typhosus (Bac- terium typlii) of Eberth and Gaffky. Modern sanitation and the study of the life history of the infecting agent, have reduced the frequency of the disease, and promise, with the intelligent cooperation of the lay world and the medical profession, to efface it entirely. BACTERIAL DISEASES 85 Typhoid Immunity Through Vaccination The surprising results of inoculation with the antityphoid vaccine as reported by Firth, Major Russell of the United States Army, and many others in all parts pf the civilized world, are so convincing that it may be positively asserted that the scientific application of data which Russell and Firth have presented, prove conclusively that we possess in the antityphoid vaccine a prophylactic remedy, which in its results is as efficacious as is inoculation against small-pox. As the result of compulsory vaccination against typhoid in the United States Army, the disease has been practically removed. Personal communication from Major Russell and medical lit- erature give the information that during the year 1913 to July 14th, there was not a single case of typhoid reported in the United States Army, as against three cases for every 1,000 men per annum formerly. What this means to the nations of the earth can be readily understood when we con- sider the ravages of a single epidemic, or point with shame to the criminal loss of life from this disease during the Spanish-Ainerican War. Man- kind is under an everlasting debt to Major Russell and the pioneers who have worked in this field with such encouraging and profitable results. If prevention of typhoid fever is to be accomplished and its entire picture changed during the few years of education which will be needed to re- move sources of infection, there must be concert of action of those who are in charge of our departments of public health and the public—this means a campaign of education in which our profession must take a leading part. Typhoid immunity continues as a rule about 2-J years after inoculation. Firth shows that “even after 4 or 5 years—the maximum period of observation—the rate per thousand among the inoculated is, roughly speak- ing, only one-fourth that of the unprotected troops.” In 1911 among “80,000 persons vaccinated in the army,” there were twelve cases of typhoid with one death, due to intestinal hemorrhage; in 1910, six cases appeared among the vaccinated, with no deaths. Without inoculation, there would have occurred “at the prevailing rates of inci- dence” 250 cases. We have now had sufficient experience with antityphoid vaccine to con- clude beyond peradventure that it modifies the severity of the disease, lowers the death rate and acts as a prophylactic. To lower the death rate, it will in the future be considered necessary to consider every convalescent from typhoid a “carrier”—a menace to the public—unless he is properly treated and Avatched. In all these cases inocu- lation with antityphoid vaccine should be obligatory. It is the best we have to offer in the present state of our knowledge. In all civilized coun- tries there has been a change in the lowering of the mortality due to typhoid infection which is most encouraging. Thus the following table tells its OAvn story: 86 SPECIFIC INFECTIOUS DISEASES Mortality Due to Typhoid Fever per 100,000 Population 1851-1860 1861-1870 1871-1880 1881-1890 1891-1900 Berlin 96 83 62 20.5 5.9 Vienna 221 110 64 13. 6. Paris 67 80 65. 25. London 24 19. 14. . In Central Uew York, cases in which the surroundings are favorable, with rational modern treatment show an average mortality between 5 and 7 per cent. Hospital statistics are less favorable but do not by any means equal the mortality of former years. In my service in a general hospital, the mortality has never during the past 10 years been higher than 10 per cent. In our own country, the United States, we must confess to our shame that in 1910 there were approximately 25,000 deaths due to typhoid fever. Germany lost but 2,856 lives during the same year and offers an apology for that mortality. A search would disclose criminal carelessness on the part of individuals and municipalities in the majority of these cases. In connection with the consideration of prophylaxis and prognosis, it might be wise for our lawmakers and departments of health to consider the monetary loss associated with these deaths. Such study and intelligent action would promptly change our statistics. Based upon the computation of Biggs, the loss due to typhoid deaths in the United States alone, during a single year, is in the neighborhood of one hundred million dollars. Factors Influencing Prognosis The prognosis of typhoid fever is often difficult, and at times it is impossible to offer a reliable forecast in the individual case because we have no gauge which tells of the depth of the lesions, nor their extent; nor can we be certain that the complexion of the mildest case may not suddenly change for the worse because of hemorrhage, perforation or other unexpected complication. We must therefore reason from the influence of separate symptoms, complications, etc., on the course of the disease. All forms of typhoid, however mild, should be considered serious. Yo acute infection is so likely to change the character of its symptoms as is typhoid. The severity of the third week of the disease may be out of all proportion to the benign character of the previous period. It is generally supposed that the prognosis of typhoid is more serious in hot than in cold weather. The disease is less serious toward the end of an epidemic than at its height. In some families there is a decided predisposition to the development of the infection. Enteric fever is unfavorably influenced by pregnancy, childbirth and the puerperal period. Pregnant women are likely to abort; The progno- BACTERIAL DISEASES 87 sis is not however absolutely bad in any of these conditions, though the lowered resistance and vitality must be considered. Morphinists, alcoholics and the subjects of chronic disease bear the infection badly. The prognosis of typhoid is materially influenced by: 1. The resistance of the patient. 2. The severity of the infection and 3. The character of the complications. 1 Resistance of the Patient I have already referred to the beneficent influence of antityphoid vac- cination. It is an established fact that resistance is heightened by previous typhoid infection, and Russell as well as Kutcher have proved this fact by incontrovertible evidence. Age.—Clinicians are all agreed that the prognosis of the disease dur- ing early life is more favorable than in adult life. My experiences show a mortality of 5 per cent in children; considering my statistics'of hos- pital and private cases I find the mortality between 10 and 12 per cent in the adult. The prognosis during the first year of life is unfavorable. Be- ginning with the sixtieth year the mortality is surprisingly high, but the disease is rare. The most dangerous period (Fornet) of the disease in women, who show a mortality of 12.7 per cent is between the fifteenth and nineteenth year of life. In men, the mortality in a large number of cases was 11.7 per cent, and the greater number of deaths between the thirtieth and thirty-fourth year. In a material including 11,000 cases of typhoid (Fornet), the mortality ranged between 10.8 and 11.4 per cent. Young, plethoric, obese, and mentally active adults (twentieth and fortieth years of life), offer a less favorable prognosis than do the thin and less active of the same age. 2 The Severity of the Infection In a small proportion of typhoids the malignancy of the infection is early manifested. There are cases, fortunately rare, nevertheless suffi- ciently frequent and important to demand consideration, in which without a prodromal period the patient is at once found violently ill, usually after a single severe chill or repeated light chills, with hyperpyrexia and other symptoms of deep constitutional invasion. In some of these, meningismus typhosus is an early accompaniment. In children this type is less dan- gerous than in the adult; with the latter, this foudroyant type offers a very grave prognosis. Curschman has called attention to a class of cases in which the infection is so malignant as to present fully developed and severe symptoms during the period of incubation. In all of these type3 88 SPECIFIC INFECTIOUS DISEASES in which the early symptoms are threatening, the prognosis is materially influenced by the rapidity of the pulse; and I am inclined to place consid- erable prognostic value on facial expression, and the mental state of the patient. Cases in which there is early hyperpyrexia, wdiich refuse to yield to treatment, in which there are no marked remissions, likely to be associ- ated with cerebral symptoms and rapid pulse, justify a very guarded prog- nosis; usually die early and are expressive of malignant infection. Experienced clinicians have repeatedly called attention to the decided variation in the malignancy and in the nature of different epidemics. In some of these, the cases are uniformly severe, in others the prognosis proves favorable and complications are either rare or if present, mild. These anomalies of behavior we cannot explain. There are epidemics in which the character of the eruption is hemorrhagic and the disease is likely to be severe. This does not, however, always follow, for in central and north- ern Hew York during mild epidemics and in isolated cases we have had hemorrhagic skin lesions which made uninterrupted recoveries. As a rule an epidemic in which the lesions are hemorrhagic offers a less favorable prognosis than does the usual roseola eruption. However, before reaching conclusions in these cases associated conditions should be thoroughly con- sidered. Malignant and severe infection is likely to show its effect on the myo- cardium early. Heart weakness, circulatory insufficiency early, is often attributable to the direct effect of typhoid toxemia on the heart muscle or to the paralyzing influence of toxins on the spinal centers and vasomotors. With these conditions there is lowering of arterial pressure, rapid and unsatisfactory systolic contraction, and often a lowering leukocytic count. With malignant infections the blood-stream is overcharged with typhoid bacilli, and Schottmiiller has demonstrated the persistence of typhoid ba- cilli in the blood in these cases in large numbers during long periods, while Liidke and Sturm have further demonstrated to the satisfaction of the German profession that the severity of the constitutional symptoms in typhoid fever is in direct proportion to the number of bacilli in the blood- stream, and that collapse is attended with enormous bacteremia. Hence a count of bacilli in the blood should prove of prognostic value. Schott- miiller’s highest count was 202 bacilli in 10 c. cm. of typhoid blood. This comparatively low count was made before the use of bile-agar, which gave Schiiffner (cited by Schottmiiller), a count of 872 bacilli in 1.5 c. cm., and which may now be depended upon to give positive data in 50 per cent of all cases. 3. The Influence of the Complications of Typhoid The influence of the complications of typhoid deserves separate con- sideration, and this it will receive in the following pages. BACTERIAL DISEASES 89 In a large percentage of cases the height of the fever at the end of the first week of continuous symptoms offers a fair index of the severity of the disease in uncomplicated cases. Typical cases during the second week of symptoms, with temperature not higher than 103°F., pulse 100 to 110, and respiration not above 24 per minute, may be considered mild, and without complications offer a very good prognosis. In all cases of typhoid fever, a decided daily fall of temperature, making it possible for the heart to rest, and reducing the ravages of too rapid oxidation and consequent degeneration, influences the disease favorably. Such patients are able to bear the disease longer and better than do those whose temperature remains continuously high. It is a further fact that with a remission daily, higher temperatures are better borne than lower temperatures without decided fall; therefore I would formulate the following rule: A decided fall of temperature daily, during a period varying from 2 to 4 hours, associated with a corresponding lowering of the pulse, is of decided advantage to the typhoid patient. There are cases with indefinite symptoms during the first two and sometimes three weeks of the disease, with indefinite and irregular rises of temperature, often not above 102°F., occasionally from 100° to 101°F., in which the agglutination test is long postponed, and in which abdominal symptoms during this period are likely to be absent. These may, before the termination of the disease, present serious features, making the prog- nosis problematic for long periods. The foudroyant type already men- tioned in connection with malignant typhoid, plunges the patient into high fever at once, within 24 to 48 hours, without marked remission. The pulse is rapid, in some cases tense at first, becoming promptly dicrotic; there is early cerebral invasion, dry tongue, marked subsultus, occasional convulsions in children and young adults, and often opistho- tonos with other cerebrospinal symptoms. This type offers a very unfavor- able prognosis; the patients die as a rule within the. first week, or early in the second week of the disease. These cases present all of the features of deep toxemia. Most of the patients are robust adults, over twenty and below the 40th year of life. In some of these cases mixed infection has been considered as the cause of the foudroyant and malignant nature of the disease (Port). On the other hand Lenhartz has obtained pure cultures of typhoid bacilli from the blood in these cases without either ulceration or swelling of the intestinal glands. (See Typhoid, without intestinal lesions.) Temperature and Prognosis Prognosis in Various Forms of Typhoid Protracted Fever.—There are frequent cases—the majority of which are only moderately severe, though a few may he considered severe—in 90 SPECIFIC INFECTIOUS DISEASES which the fever persists during unusually long periods. These may cover a febrile period varying from 4 to 6 or even 8 weeks. I have the notes of a case which terminated favorably, in which on the ninety-sixth day of the disease, without known complications and without preceding decided re- mission, the temperature still averaged 102 °F. As a rule it will be found that in these cases the fever is of an intermittent character and atypical. In the majority of these cases the prognosis is favorably influenced by the relatively short or even normal period of continuous fever, and the decided remissions during the longer period of intermittent fever. If in these cases of prolonged fever the digestive organs do not revolt, and there are no other serious complications; in spite of extreme weakness and muscular wasting, full recovery may slowly follow. These cases are likely, after the long postponed afebrile period is established, to have rises of tempera- ture on slight cause. An occasional case of this kind passes beyond the long period of fever, but fails to lift itself from the weakness which fol- lows ; wasting continues, the appetite does not improve, the organs of diges- tion become intolerant, vomiting is often an uncontrollable symptom, the abdomen is abnormally resistant and retracted, and death follows weeks or months after the initial symptoms of typhoid. There is another set of cases in which without knowm cause a slight fever persists long into the period when full convalescence is expected; which yields promptly, and offers a changed prognosis so soon as the patient is allowed to sit up and move about cautiously. Delafield called attention to these cases years ago. Abortive Typhoid and Mild Irregular Typhoid (Typhus abortivus, Typhus levissimus).—In America we meet but few cases of the abortive types of the disease ; that these are occasionally found in the midst of endemics or epidemics we cannot deny. Some of these correspond with the description given by the older writers of ephemeral fever (febricula). The majority of these cases offer a favorable prognosis. They are all char- acterized by a short febrile period. Liebermeister’s classification of these cases as 1. Typhus levissimus 2. Typhus abortivus is most satisfactory. 1. Typhus levissimus. (Mild Typhoid).—In these cases the disease does not seem to be fully developed. The febrile period may be short and mild; one or more of the usual leading symptoms of the disease may also be of short duration, even in the presence of a slight continuous febrile movement. In occasional cases there is a remittent type of fever, in others the curve is irregular and erratic. The pulse in favorable cases is scarcely changed in character or in frequency. The general condition of the patient continues good. The disease ends in recovery as a rule between the four- teenth and twentieth day of the disease, without marked invasion of the sensorium. In occasional cases the early days of a mild typhoid may BACTERIAL DISEASES 91 include high fever with other transitory constitutional symptoms, but they soon prove to be benign because of the decided change in the nature of all attending conditions. In the United States cases of this kind such as Liebermeister has described, running their course in from 6 to 8 days, are among the clinical rarities. Mild typhoids may be followed by slow con- valescence. The enlarged spleen is in evidence early in most cases. 2. Typhus abortivus (Liebermeister).—Occasionally a free out- spoken fever, early, with deep invasion of the sensorium at once—but with a reassuring pulse—runs a short course and may lead either to prompt or to slow convalescence. In these cases the severe headache during the first week, complete anorexia and apathy, occasionally a single heavy chill and early enlargement of the spleen, are not to he interpreted as arguing against a favorable prognosis. In these as in all cases of typhoid the pulse (myo- cardial condition), and the frequency of the respirations offer data which must be given great weight before safe conclusions are justified. In some of these abortive types the fever may return to normal within 9 to 14 days. Most of these cases, however, begin with a decided chill; after a short pro- dromal period, the temperature rises promptly; there is as a rule- some apathy with sleeplessness; there may be delirium; the roseola eruption is found early; but the pulse is likely to continue good. Complications and distant typhoid infections (liver, gall-bladder, lung, heart, etc.) occur, but are less serious and less frequent than with the usual types of the disease. The light form of typhoid (levissimus) differs from the abortive type in several particulars. In the former the constitutional symptoms are fewer; symptoms referable to separate organs are unusual; the tempera- ture is higher and associated with greater wear and tear in the abortive type; while albuminuria is more frequent, with casts (hyalin, granular, and blood). Roseolse are fewer and less constant in the abortive than in the typical disease. In both types of irregular fever considered, tympany and diarrhea are not as a rule disturbing. A full consideration of these earmarks will make it comparatively easy to prognosticate in these cases; but it must be remembered that none of these patients is immune to per- foration, peritonitis, hemorrhage or pulmonary complications. These added dangers are not frequent. Relapses are frequent after the milder types of fever and these may run a more typical course than did the origi- nal infection. The prognosis remains uncertain for days following the beginning of the relapse, but usually proves good. Ambulatory Typhoid (Walking Typhoid Fever.)—Most cases of am- bulatory typhoid may safely be considered to have been neglected. In these, patients have continued about, in spite of a prodromal stage and a train of continuous symptoms which, in all probability always include some elevation of temperature. The fever in these is not so high as in the usual cases ; there is less exhaustion and malaise attending it early; but the picture which is finally presented by these, cases is often serious and the 92 SPECIFIC INFECTIOUS DISEASES outlook grave. This is particularly true of those typhoids who have been exposed to the hardships of travel. My experience justifies the conclusion that travel adds enormously to the dangers of every fully developed typhoid. While ambulatory typhoids may present with normal temperatures during the early hours of the day or during almost the entire morning, close observation will show some elevation later in the day. The pulse in spite of low temperature or afebrile state is rapid, as a rule, when these patients surrender, and there are often subjective complaints, including palpitation. In hospital cases I have often noticed more or less incoherence on admis- sion. I have learned to give a very guarded prognosis in these cases; they run an uncertain course, are likely to develop grave abdominal complica- tions—endocarditis, pulmonary infarct and infection, thrombosis, abscesses —and what I fear most, degeneration and dilatation of the heart muscle. There are on the other hand ambulatory cases so mild as to give no un- easiness, running a smooth and uneventful course to full recovery. Afebrile Typhoid.—Cases of feverless typhoid are not frequent; they do, however, occur. They are likely to be found in homes where several typical cases of the disease exist. In some of these the temperature has remained normal throughout, others have shown a slight elevation usually toward night of from -|0 to 1°F. In all the diagnosis has been confirmed either by a positive Widal reaction, or by blood cultures, or by both. With- out fever, the associated symptoms referable to the abdomen have per- sisted. Unquestionably a number of so-called “latent cases” to which Koch referred, belonged to this class. Tie held that these cases existed without marked symptoms, were not as a rule reported to the public health authori- ties, and that they continued to be a menace. The Trier Commission drew attention to the dangers to the public of these cases, and established the fact that the number of infected cases in Trier was nine times greater than the number “sufficiently ill to require treatment.” The majority of afebrile typhoids recover: death may follow, as has been reported by Strube and F rantzel. In the aged, afebrile typhoid, in the presence of chronic cardiovascular and renal disease, offers but little that is encouraging; in alcoholics and those reduced by previous disease the prognosis is correspondingly bad. Sudden fall of temperature is occasionally met when not of serious import. It should always be viewed with suspicion and the patient should be carefully observed, that its significance may not be misinterpreted. The fall may presage a favorable termination, for it has been my experience that in a majority of cases in which the true cause of the fall has not been made clear promptly by the development of positive symptoms, there has been a rise of temperature within 12 to 24 hours and then a gradual return after a varying period to normal or, if there are no added compli- cations, with a more or less irregular behavior the fever has gradually sub- sided In these cases the decided fall of temperature is not associated with BACTERIAL DISEASES 93 the symptoms of collapse due to profuse hemorrhage, nor the pain and physical signs referable to the abdomen which are characteristic of per- foration, nor the added evidences of circulatory embarrassment, which occasionally develop suddenly at the height of the typhoid infection. Sudden effacement of liver dulness with fall of temperature, abdominal pain, and collapse, is suspicious of perforation and justifies a serious prog- nosis. Blood pressure study will in the presence of perforation and begin- ning peritonitis show a slight, but easily demonstrable rise to promptly fall after a few hours, and may prove of prognostic as well as diagnostic value. Post-typhoid Pyrexia.—Transitory elevations of temperature which may last a short time during the period of convalescence are not of serious import. In some—particularly nervous subjects—excitement, worry, mus- cular effort, a hearty meal, or errors in diet during this period prove suf- ficient to cause these sudden rises. Long continued obstipation may also provoke insignificant exacerbations. Hypothermia, persisting for several days, mentioned by Osier, is also without unfavorable influence. In some of these cases the pulse has been erratic, occasionally slow and irregular, in others, abnormally rapid during limited periods. Circulatory Disturbances in Typhoid Pulse.—It is fortunate that the pulse of typhoid fever is in most cases slow in comparison with the temperature. In no other long continued acute infection does the heart behave so favorably. The pulse offers the safest indications for prognosis in typhoid fever. With a pulse, of good character, and average frequency of 100, in spite of an elevation of tem- perature of 103° to 104°F., the prognosis continues good. As has already been stated, remission of fever during the day with associated drop in heart frequency is favorable. When the pulse is persistently high, whatever the temperature—if above 120 to 130—there is serious complication, or heart weakness threatens. When the pulse, which during the first two weeks has been reassuring, begins to intermit in the third week, is irregular and rapid with feeble heart sounds, possible dilatation must be considered sug- gestive of myocardial insufficiency. When, with such a pulse there are evidences of pulmonary congestion or edema, consolidation, or bronchial catarrh, the prognosis is exceedingly grave. Cyanosis with evidences of myocardial insufficiency and correspondingly rapid pulse justifies an un- favorable prognosis. Rapid pulse with deep invasion of the sensorium is of serious import. Restlessness and insomnia with delirium add to the danger. With rapid pulse (120 to 140) and hurried respirations (30 to 50) the patient must always be considered to be in a serious condition, and search will usually reveal pulmonary, renal, cerebral or other complication, though a tired heart with consecutive stasis may explain the symptom 94 SPECIFIC INFECTIOUS DISEASES complex. Dicrotism at the height of the disease, if the heart is not abnor- mally rapid, is not as a rule unfavorable. There are but few cases of en- teric fever in which there is not more or less dicrotism at some time. Rapid pulse is the rule with infantile typhoid and does not argue against a favorable outcome of the disease. After the sixth or eighth year of life the character of the pulse and its frequency in children approaches that of the adult. As the disease advances, blood pressure is likely to be lowered and the pulse amplitude correspondingly changed. The pulse is softer and smaller: this is a natural result of toxemia and not unfavorable. Persistence of normal blood pressure is favorable. Increased frequency of the heart with sudden fall of blood pressure is unfavorable. Increase in the frequency of the pulse toward evening, with a reassuring condition during the day does not change the prognosis. In all cases there is likely to be a close rela- tion of temperature and pulse. With a rapid pulse early in the disease whatever the change of blood pressure, unless such condition depends on a neurotic state or the patient normally had a rapid, irritable heart, that organ is likely to prove insufficient. The heart itself is in most cases the seat of interstitial and degenerative changes (myocarditis). The extent of such changes is shown by the weak and muffled systolic sound, mitral systolic murmur—due to relative insuf- ficiency—accented II. pulmonary sound, distant heart sounds—embryonic in character—marked change in rhythm, and in severe cases decided dilata- tion of the ventricles. The early signs of cardiac weakness are due to vasomotor paralysis; the evidences of myocardial degeneration follow. Sudden Death.—Approximately 1.2 per cent of typhoids die suddenly from a variety of causes, among these myocardial invasion. Degeneration is the most frequent; thrombosis, embolism, cerebral apoplexy, pulmonary edema—due as a rule to circulatory insufficiency, and renal invasion, de- generative in character—are also to be considered. A distinct mitral systolic murmur with accented II. pulmonic sound is not of serious import unless there are other marked evidences of heart Aveakness in rapid pulse, etc. Diffuse apex-beat with rapid heart is deserving of careful consideration and is, if persistent, indicative of serious cardiovascular disturbance. In many patients, unless the nervous system, is profoundly involved, the pulse as counted by the physician is likely to be somewhat accelerated, hence the average count of the nurse must also be considered. Relatively sloiv pulse with dicrotism and normal arterial resistance, or only slightly lowered blood-pressure, is not of se- rious import. Sudden increase in the frequency of the pulse with or without evidences of collapse is ahvays ominous, and will be fully con- sidered in connection with intestinal hemorrhage, perforation and other complications. The crossing of the temperature curve by the pulse curve is suggestive of increasing danger. BACTERIAL DISEASES 95 Bradycardia following rapid pulse, particularly during the convales- cent period or in the terminal febrile stage, is not of serious import unless it is an evidence in young or in old subjects of heart block. Any change in the coronaries or disturbance of conduction {Stokes-Adams) adds a decided handicap, and materially lowers the chances of recovery. Accented aortic II. sound with increased ventricular effort and force- ful impulse, suggest a compensatory effort to overcome vasomotor paraly- sis in the periphery, usually in the domain of the splanchnics, and unless relieved overtaxes the cardiovascular system and leads to cardiac asthenia finally (Ortner). It not infrequently happens that the pulse rate is higher during periods of relapse than it was originally. Every case of typhoid fever during convalescence or after recovery may show some ab- normality of function or organic cardiovascular change. Of all modern clinicians, Thayer deserves the greatest credit for having demonstrated the fact that arteriosclerotic changes are unusually frequent in patients who have had typhoid, as well as other functional and organic heart lesions. Posttyphoid myocarditis may be the cause of symptoms during con- valescence in which the slightest excitement or muscular effort provokes palpitation or some subjective complaints referable to the heart. These types of myocarditis lead to complete recovery within a few months. If the pulse is persistently rapid during the period of convalescence with gradual improvement in the general condition of the patient, gain in weight, and good appetite, the heart will after a reasonable period of rest with moderate exercise, return to its normal state. Rapid pulse per- sisting during convalescence, without increase of weight, slight evening rise of temperature, general condition beloAV par, must lead to the sus- picion of some added infection—possibly tuberculosis, pus deposit, or other hidden complication. In severe cases, besides vasomotor paralysis already mentioned, there are anatomic arterial changes (Wiesel) in which the media is involved in a process of atrophy, connective tissue change, and lowered arterial resistance. This adds an element of danger which is overcome in the average case. Thrombosis.—Phlebitis cruralis.—Thrombosis of the anterior cru- ral is a frequent complication which fortunately as a rule follows either toward the end of the acute fever, or early during the period of convales- cence. While it is often exceedingly painful and causes in all cases more or less fever and acceleration of the pulse, it usually leads to full recovery after weeks or months. Occasionally double crural phlebitis postpones convalescence. I have never seen a case which led to gangrene, but rarely a detached bit of thrombus has led to fatal embolic infarct. Thrombosis or septic thrombophlebitis may invade any vein, and add a complication of serious import—pulmonary, portal or cerebral thrombosis —fortunately rarely encountered. 96 SPECIFIC INFECTIOUS DISEASES Arteries.—Arteries may occasionally be occluded by either an embolus or thrombus. The complication is rare, not necessarily fatal; it may lead to gangrene. Holscher claims that 1 per cent of all typhoid deaths are due to embolism of the pulmonary artery. Limited superficial losses of tissue due to embolic infarct or arterial change heal slowly as a rule; their prognostic significance depends upon the cause and source of the embolus. If due to endocarditis, the latter may prove malignant or septic; then the prognosis is bad. Gangrene.—Gangrene due to thrombosis, embolism, or arteritis may prove serious when extensive. It is not a frequent complication; usually is unilateral, and involves one lower extremity. In all of these cases associated conditions, sepsis, and the extent and location of the process must be considered. Invasion of the iliac, femoral or posterior tibial is most frequent. In rare cases the prognosis becomes absolutely bad be- cause of double symmetrical and far-reaching gangrene (Trousseau, Potin, Mercier, Bachmayr and Dodd). The occurrence of double gan- grene is so rare that in an active hospital experience covering over thirty years, not a single case has presented. Pericarditis.—WThen positive symptoms, subjective and objective, of pericarditis present, these are due as a rule to septic infection, which is likely to be purulent and which adds a. factor of danger to an already serious condition. Holscher, in an analysis of 2,000 typhoids found this complication in .7 per cent of cases. Endocarditis.—Endocarditis arising during the course of the disease is not frequent. Occasionally with mixed infection the endocardium has been involved. It requires caution to eliminate in diagnosis the malignant endocarditis of typhoid type but not typhoid fever, in which the prognosis is always bad. In 2,000 typhoid autopsies (Holscher) there were 11 cases showing acute endocarditis, i. e., .5 per cent. Disturbances in the Respiratory Organs Respiration.—The safest indications for the prognosis of a typhoid patient are offered by the pulse (heart) and the respiration (lungs). With a reassuring pulse and no evidences of serious pulmonary involvement or embarrassment of any kind, as shown by hurried or labored breathing, the outlook may in the overwhelming majority of cases be considered favor- able. Most serious complications will at once accelerate pulse and respi- ration. Rapid respiration without evidences of cardiac or pulmonary involve- ment, out of proportion to the height of temperature, unless of purely functional origin (hysteria, fear, neurosis) is always suggestive of a serious complication; its true significance can only be decided after its cause has been unearthed. Occasionally diabetes mellitus with acidosis BACTERIAL DISEASES 97 in a typhoid subject has been found to be the cause of hurried respira- tions. In other cases profound toxemia has proved to be the cause with- out high temperature but with great exhaustion; finally, with rapid heart such patients succumb to the disease. In the majority of typhoid cases pulse and respiration bear a close relation to the temperature; in a large number of cases however in which the temperature reaches a high degree, respiration is not markedly changed. These are favorable combinations. The cause of rapid res- pirations in any case determined, the prognostic significance is easily cleared. Considering pulse and respiration together, I would submit the fol- lowing: With acute typhoid infection a rapid pulse is always more omi- nous than a high temperature, hut with such complications as pneumonia or mixed infection, hurried, abnormally high respirations are more seri- ous than a rapid pulse. Where the two are present together, i. e., rapid pulse and abnormally frequent respirations, at the height of the acute disease unless one can be sure that the symptom complex rests on hysterical fundament, the prognosis is exceedingly grave. Most enteric fevers are associated with catarrhal changes in the upper respiratory tract and included bronchi. The ordinary nasal changes have no influence on the course of the disease, save as the dry mucosa, crusting, and at times ulceration with possible perforation, add to the discomfort of the patient. Epistaxis.—ISTosebleed is present at some time as a rule—usually early—and unless profuse is of no prognostic significance. Repeated profuse nosebleed with other evidences of hemorrhagic disease, usually with grave constitutional disturbances, often deep involvement of the sen- sorium, dry tongue, crusting, and sordes on teeth whenever present, is ominous—this symptom complex is not infrequent in chronic alcoholics with typhoid fever. Catarrhal Pharyngitis and Laryngitis.—Catarrhal pharyngitis and laryngitis do not influence prognosis materially. Deep ulceration of the larynx, with or without edematous swelling are usually found on the posterior laryngeal wall, and often with the more malignant types of the disease. The edema alone may threaten the life of the patient and de- mands) prompt relief, otherwise death follows. When ulceration leads to necrosis, perichondritis, cutaneous and deep emphysema, the outlook is bad. The mortality is as high as 40 to 50 per cent (Tiirck). In occasional cases, deep ulceration with destruction of tissue leads to stenosis if the patient recovers, demanding tracheotomy and the permanent or long wear- ing of the tube. Uncomplicated laryngeal ulcerations are not infrequent, as has been proved by post mortem study; they may be present without causing symptoms and in the majority of cases heal permanently, with- out deformity. 98 SPECIFIC INFECTIOUS DISEASES Bronchitis.—Bronchitis, present in practically all cases of typhoid —when uncomplicated, does not lower resistance or influence prognosis. Extension to the finer bronchial tubes (bronchiolitis) is common in the severer cases, and is therefore of grave import. Consecutive ateleclasia adds another factor of danger, but unless bronchopneumonia (lobular pneumonia) follows, the prognosis, though grave, may yet hold hope of recovery. Disseminated islands (lobular) of pneumonia with atelectasia is a serious complication in all cases, and in all ages. Hypostatic Congestion.—Hypostatic congestion, usually found in the lower lobes, is serious in proportion to the added obstruction which it offers to the heart—always serious, when extensive—in the presence of a weak myocardium and deep infection. Pneumonic infection of the hypostatic lung, i. e., hypostatic pneumonia, is as a rule life-threatening, always a serious complication, and often ends in death (50 per cent). Children rarely develop more than transitory hypostatic congestion, and are not prone to have added pneumonia: this is due to the shorter dura- tion of the disease and relatively infrequent heart weakness. Pneumonia.—Pneumonia (lobar, i. e., croupous) is a serious compli- cation of typhoid fever. In the larger number of typhoids' this complica- tion (Fraenkel-Weichselbaum diplococcus) is developed during the height of the disease, near the end of the fever or during convalescence early— rarely late. As a rule there are early evidences of heart weakness, rapid pulse, and decided lowering of blood-pressure, with characteristic res- piration—all of which affect prognosis unfavorably. Cyanosis added to these conditions is serious. My experience with pneumonia in typhoid fever has been exceedingly unfortunate: over 50 per cent of these have died. It is exceedingly rare to find a favorable outcome after the fortieth year of life. Lobar pneumonia complicates typhoid in from 5 to 7 per cent of cases, the lobular form in 8 per cent. There are occasional cases of typhoid in which the early symptoms are clearly those of pneumonia, so-called pneumotyphoid, in which the lung may clear, and the patient falls into the continuous and characteristic symptoms of typhoid fever. Invasion of bronchial glands—suppuration—may prove serious, and occa- sionally leads to empyema. Strepto- and staphylococcus infection of the lung with typhoid, mixed infection, including the Bacillus typhosus, caus- ing either lobar or lobular pneumonia, always demands a guarded progno- sis. The pure pneumococcus infection offers a better prognosis than does the streptococcus. Lung Abscess.—Lung abscess is rare. If it follows pneumonia com- plicating typhoid, gangrene may finally develop, and death is the rule. Pulmonary Infarct.—Pulmonary infarct may cause hemoptysis; if small, it may lead to no serious condition, but if large or if it causes gan- grene and sepsis, or if caused by vegetating typhoid or septic endocarditis, the prognosis is bad. Gangrene has already been mentioned in connection BACTERIAL DISEASES 99 with lung abscess and pulmonary infarct. As a rule it is associated with or follows lobar pneumonia, develops late in the course of the disease. An idea of the frequency of gangrene can be obtained from the following figures: Liebermeister in 230 deaths from typhoid found 14 cases of gangrene; Griesinger in 118 found 7; Curschmann—Leipzig statistics— in 228 found 10 cases; Hdlscher in 2,000 autopsies of typhoids found 40 cases, or 2 per cent. Murchison considered pulmonary gangrene exceedingly rare, having met the complication only twice. The prog- nosis is bad. Pulmonary Edema.—Pulmonary edema arising in the course of typhoid without other pulmonary or cardiac complication is rare, always serious, hut not necessarily fatal. Our experiences do not justify the high per- centage, i. e., 14 per cent, of this complication as reported by Holscher. Simple non-tuberculous serous pleurisy is not as a rule serious, but it re tards recovery if it arises late. It is naturally associated with the pneu- monias of typhoid, and as already stated, these offer a serious outloox, depending on conditions mentioned in the consideration of pneumonia as a complication. Purulent Pleurisy.—Purulent pleurisy, i. e., empyema, complicating typhoid, usually following pneumonia, may under some conditions prove serious. The prognosis depends on many factors: time of complication, resistance and general condition of patient, time of recognition, ability to relieve by prompt and thorough drainage. Bloody and foul effusions with, typhoid are always indicative of malignant infection. Pulmonary Tuberculosis.—It has been the experience of most clini- cians that associated tuberculosis of the lung with typhoid is due to the awakening of latent tuberculous disease which antedated, as a rule, the acute infection. If the process is of the acute miliary type it may be difficult, if an early complication, to differentiate without blood-culture and agglutination tests. In all cases of miliary tuberculosis complicating typhoid, the prognosis is unfavorable. Limited tuberculous deposits, i. e., infiltrating tubercle without disor- ganization, which have been lighted to activity by the typhoid process, under favorable conditions and environment, may yield to treatment and a return to latency. Pneumothorax.—Pneumothorax (pyopneumothorax) I have never met in connection with typhoid. It is an exceedingly rare complication. In the reported cases it wTas dependent on some one of the conditions (pneu- monia, tuberculosis, etc.) mentioned, and the outcome has been fatal. The Blood The blood offers some data which may serve in the prognosis of typhoid fever. The albumin and iron content of the blood are reduced in propor- tion to the severity of the disease. Fibrin is also below the normal unless 100 SPECIFIC INFECTIOUS DISEASES it is increased by complications, such as disseminated bronchitis and pneu- monia. In most cases of typhoid a moderate anemia gradually increasing as the disease advances is the rule, and not unfavorable. Thayer, Win- ter, and Curschmann have shown that in the average. favorable cases there is during the first days slight reduction in the number of red cor- puscles; with young powerful men, this is less marked than in women or in the weak. The former give an average count of four million, the lat- ter three million. The reduction continues until the end of the febrile period and during the early days of convalescence. Then the rise begins in favorable cases, usually in 2 to 3 weeks. The clinician is not to be discouraged if the normal count is slowly reached; this is the rule. Ilelapses may give lower red counts than were found with the original fever, and yet the prognosis remains unaffected. Hemoglobin in the average favorable case does not sink far below 70 per cent. Sudden anemia is suggestive of intestinal hemorrhage. The leukocytic count is of considerable value. The tendency in typhoid fever is toward low leukocytic counts—possibly the first day of the disease and of relapses excepted—when it may reach 10,000. The average count in adults during the first stage is from 2,800 to 4,500. The more serious the infection the lower the count. Leukopenia must be expected in typhoid fever (85 per cent). The period of convalescence finds the patient with a normal count. Neutrophilic leukocytes are increased during the first days of the dis- ease, but as the symptoms increase in severity the count of these falls as low as 1,000 to 2,000. With improvement, when the patient is fever-free there is an increase, a gradual return to normal; often the count mounts above the normal (Schottmtiller). There is prompt disappearance of eosinophils from the typhoid blood. Return of eosinophils is an encour- aging feature; as a rule this indicates convalescence. There is a progressive decrease of lymphocytes during the active period of fever; their return, like the return of eosinophils, is favorable. If with complications such as pneumonia, intestinal hemorrhage, per- foration, diarrhea, pus accumulation, and nephritis (acute), marked leuko- cytosis is absent, particularly neutrophilic leukocytosis, prognosis is unfa- vorably influenced, because, as Schottmiiller has suggested, there is an in- ability of the bone marrow to react. The following are safe conclusions for prognosis: The persistence in typhoid blood of even a few eosinophils is a favorable feature. Relatively high neutrophilic values without complications are also favorable. Increase of lymphocytes argues in favor of a decline of fever. Marked leukopenia, particularly a low lymphocytic count, is unfa- vorable. With the complications already mentioned low leukocytic counts argue in favor of serious conditions. Blood counts alone should never lead to positive prognosis for there are cases in which in spite of severe BACTERIAL DISEASES 101 leukopenia, that is, low values, patients have made full recov- eries. In considering the malignancy of typhoid infection we called attention to the fact that the disease is severe in direct proportion to the number of bacilli found in the blood stream and that a count of bacilli in the blood was of great prognostic value (See references to Schottmuller’s and Schiiffner’s experiences). Disturbances of the Alimentary Canal The Mouth.—The organs of digestion offer valuable prognostic data. In serious cases the lips are abnormally dry, crusty, and often cracked and bleeding. In favorable cases, the lips are moister, with less evidence of change. In unfavorable cases, there is associated dryness of the mouth; the buccal mucosa is materially changed, ulcerated and bleeding, with sordes on teeth; gums incline to bleed. As a rule with these changes there is a dry tongue, covered with a thick brownish dirty coat, red at the tip and shining. The above picture, with marked fibrillary twitching of the tongue, is usually associated with cerebral invasion and is found in the more serious cases. Such conditions early, argue in favor of a severe course of the infection. The tongue is changed in practically all cases, and its study is often a valuable prognostic index. A dry cracked tongue, slowly protruded, long exposed, returned only after repeated suggestion, with apathy or mut- tering delirium, is characteristic of severe deep toxemia and is serious. Moderate f brillary twitching of the tongue is present in almost all cases and is not of serious import—less significant if the tongue continues moist and the patient is free from the symptoms of deep infection. The severer cases show the greatest fibrillary twitching of the tongue; in these the nervous system is profoundly invaded, as is shown by active subsultus tendinum and other symptoms. Moist tongue is found in the milder cases of typhoid with few mouth and lip lesions and with clean teeth or little sordes. There are cases in which changes in the tonsils are so evident as to cloud the diagnosis. Unless these are gangrenous or diphtheritic or are associated with noma, they are soon accompanied by the symptoms of general typhoid disease and do not influence prognosis. The more serious but rare complications are, as mentioned, diphtheria, deep ulceration, and noma. Parotitis.—Parotitis whether suppurative or not is always a serious complication. It is added as a rule when the patient is weakened by the toxemia and other complications; is always febrile; may occasionally be double. There is in these cases the added danger of thrombosis (jugular and cerebral), phlegmon, infiltration of surrounding muscular tissue, peri- 102 SPECIFIC INFECTIOUS DISEASES chrondritis, and facial 'paralysis. Parotitis complicates from .3 per cent to 1 per cent of typhoids, and of this number one-half die. Stomach Disorders.—An intolerant stomach is always a decided handi- cap. Persistent vomiting from whatever cause lowers vitality and re- duces the patient’s chances. When this continues, and remains uncon- trolled in the third and fourth week, with anorexia, the wasting is enor- mous ; the pulse grows smaller; the tissues are dry; and death is the rule. Persistent vomiting is at times an early symptom of added meningitis; then it is “propulsive” and associated with other positive symptoms. Sudden severe vomiting with pain, not due to error of diet or transitory disturbance, is suggestive of perforation, peritonitis, latent hemorrhage, or involvement of the appendix. I have seen two cases in which after con- valescence was fully established, uncontrollable vomiting—the cause of which was never cleared—with increasing consecutive weakness, caused death. Tympany (Meteorismus).—Absence of tympany is always favorable. Severe cases at their height are likely to be burdened by intestinal disten- tion. It is a burden, for it increases the work of the heart, displaces or- gans—the liver more particularly—and adds to the patient’s discomfort. Suddenly arising tympany with evidences of collapse is significant, for it may mean serious complication, perforation, adynamic paralysis, hemor- rhage. Early meteorism is not usually significant. In many cases proper diet will prevent or control it, if not, then it must remain a factor in prog- nosis. Modern clinicians view tympany more as an expression of general in- fection (intestinal paralysis—adynamic) than an index of the extent of the intestinal lesions. Diarrhea.—In a moderately severe typhoid in which the bowels are loose the average number of stools is from 6 to 10, many of these are finally found with serious complications referable to the intestines. Move- ments above this average (ten) denote a serious condition. If most pas- sages are involuntary and other symptoms are correspondingly severe, a guarded prognosis is justified. Frequent involuntary passages are always of grave import. In my hospital and consultation practice I have found at least one- third of all cases free from diarrhea during the entire course of the dis- ease. Occasional frequency of evacuation is more favorable than persistent diarrhea. Constipation does not affect prognosis unfavorably. Those epidemics have seemed to be least malignant in which the intestinal symp- toms, more particularly diarrhea, are fewest. In some epidemics the num- ber of constipated patients outnumbered those with diarrhea. The depth and number of intestinal ulcers do not always bear a close relation to the severity of the typhoid toxemia. Intestinal Hemorrhage.—Intestinal hemorrhage complicates from 4 to BACTERIAL DISEASES 103 6 per cent of all typhoids. The frequency of this complication varies with different epidemics. Slight admixture of blood, during the second and third weeks of the disease, is not serious, and is not as a rule followed by larger losses of blood. Women are less likely to have severe and large hemorrhages than men. Curschmann reports the days of occurrence of hemorrhage in 148 cases observed by him as follows: 6th to 9th day 12 10th to 12th day 23 13th to 15th day 23 16th to 18th day 31 19th to 21st day 17 22d to 24th day 9 25th to 27th day 11 28th to 30th day 10 31st to 33d day 3 34th to 36th day 4 After 36th day 5 148 The prognostic significance of intestinal hemorrhage with typhoid fever depends very largely upon the time of its occurrence, the condition of the patient, his resistance, the condition of his heart, and the quantity of blood lost. Different individuals react differently under similar conditions to the loss of blood. There are typhoids who may he thoroughly depleted, in whom the pulse becomes thready and exceedingly feeble, and blood pres- sure and pulse amplitude materially reduced, who for some unknown reason promptly regenerate sufficient blood to keep them alive during the critical period, the disease leading to full recovery. With high fever, previous rapid pulse, deep involvement of the sensorium, added intes- tinal hemorrhage, and marked tympany, a picture is presented as serious as any, save that of perforation, which we meet in the course of the dis- ease. Patients are better able to bear hemorrhage the nearer they are to the end of the febrile period. Hemorrhage during the early days of typhoid (ninth to the fourteenth day), if profuse or if repeated in the presence of other grave symptoms, is always serious—more serious if the patient is corpulent and in middle life. There are occasional cases which are influenced favorably by moderate intestinal hemorrhage (Graves, Trousseau). Relapses are not often complicated by intestinal hemorrhage. Chil- dren are not often found with this complication; this is due to the fact that the ulceration is not so deep as in the adult. Naturally, the more 104 SPECIFIC INFECTIOUS DISEASES frequent the bloody stools, the'greater is the danger. Sudden death due to intestinal hemorrhage is rare; in most cases repeated bloody stools dur- ing several days deplete the patient. However, in occasional cases patients are carried safely over the critical period following large hemor- rhages with associated symptoms, only to die after relatively small losses of blood from the intestines later, when the attendant had reason to feel fairly secure. The prognosis in all cases of intestinal hemorrhage should be guardedly given; the most experienced clinician can offer no positive forecast; there are always days of anxiety and uncertainty in the presence of this complication. When death followed hemorrhage in cases which serve as the basis for conclusions in this chapter it was between the fourth and seventh day as a rule—in a few cases between the ninth and fifteen day. My percentage of deaths due directly to intestinal hemorrhage is not above 20 per cent, but as already hinted different epidemics offer a different mortality. There have been epidemics in which 50 per cent of the patients with intes- tinal hemorrhage died. Ilomolle gives 44 per cent, Griesinger 31.2 per cent, Liebermeister 38.6 per cent. In our own country Osier gives a series of 829 cases, with blood appearing in the stools in 50, or 6 per cent. Of these 5 cases died, or 10 per cent. The same author gives a series of 118 cases of hemorrhage with 12 deaths, or 10 per cent, and a series of 131 fatal cases with 12 deaths from hemorrhage. He states again (ref.) that hemorrhage occurs in 7 per cent of all cases. Peritonitis.—Peritonitis either circumscribed or diffuse, from what- ever cause, always secondary, is one of the most serious complications of typhoid fever. When due to perforation of an intestinal ulcer we con- sider it the most fatal of all complications (perforative peritonitis). Perforative Peritonitis.—Time of Occurrence of Perforation.— In 73 cases Curschmann found that perforation occurred as follows: On the 11th to 20th day 23 21st to 30th day 31 31st to 40th day 13 After 40th day 6 Perforative peritonitis among children is rare. It matters little which portion of the small intestine is the seat of perforation, or what the size of the opening, the dangers are the same and death is the rule. Per- foration is found in 3 per cent of typhoid fevers. Statistics vary between 2 and 12 per cent. In men the complication is more frequent than in women. No case of typhoid, however mild or severe, is free from the possibility of perforation and consecutive perforative peritonitis until the ulcers have been fully healed, the cicatrices are strong, and the peritoneum BACTERIAL DISEASES 105 over the ulcer has been fully protected by nature’s reparative process. This means complete recovery. Prompt death with symptoms of perforation in collapse, with charac- teristic facies is the rule unless the condition is recognized within the first hour or two after its occurrence, and is relieved by immediate surgical interference. I am fully satisfied that in occasional and exceedingly rare cases, perforation takes place and general peritonitis is prevented by previous localized peritonitis and plastic organized protection. Such a case has been described in which death finally resulted from hemorrhage, and the autopsy clearly showed the earlier perforation (Eisner). The possibility of perforative appendicitis and peritonitis due to typhoid ulcer- ation of the appendix should not be forgotten. In these cases the early diagnosis with rational radical surgical treatment offers the only hope. Perforative peritonitis due to rupture of the spleen, gall-bladder, sup- purative mesenteric glands, or abscess of the liver is serious but offers a slightly better prognosis, if diagnosticated early, than does intestinal per- foration. Liver and Bile Passages Pathologic research has demonstrated the frequency of invasion of the liver, more particularly the bile passages, in typhoid fever. Jaundice is not a frequent symptom. Holscher found it in 1.1 per cent, 22 cases in 2,000 of those who died of typhoid. Previous diseases of the gall- bladder, cholelithiasis, typhoid cholecystitis or cholangitis, acute yellow atrophy of the liver, and abscess, are among the causes of jaundice with typhoid. Jaundice.—Jaundice may in occasional cases be dne to destructive blood changes—an evidence of malignancy when it is associated with hem- orrhages from various organs—hematuria, albuminuria, myocarditis, and coma; and death follows promptly as a rule. Typhoid infection of the bile passages and gall-bladder in individual cases is not to be ignored as a prognostic factor; its importance has in- creased during the past decade. Cholecystitis.—Cholecystitis may be present without causing symptoms or in any way influencing the immediate prognosis of the disease but there can be no doubt of the fact that it serves as a cause of subsequent disturbances, more particularly gall-stone formation; 30.9 per cent of Curschmann’s cases of typhoid fever followed during long periods, pre- sented symptoms of gall-stones after the original infection. Animal experimentation strengthens all conclusions which tend to demonstrate the importance of typhoid infection as a cause of gall-stones. It is a clinical and bacteriologic fact that the Bacillus typhosus finds a suit- able habitat in the gall-bladder and bile passages, and often remains there undisturbed during long periods. Thus, in considering the question of the 106 SPECIFIC INFECTIOUS DISEASES prognosis of these cases, we are not to forget the dangers of these carriers (Futterer, Chiari, Flexner). The Skin in Typhoid Roseola.—The number and location of the roseola spots have no hear- ing on the prognosis, so far as I have been able to conclude from my ex- perience. The depth of color does hear a direct relation in many cases to the severity of the infection. Thus a mottled skin, with dark, at times hemorrhagic skin lesions is expressive of malignancy. Miliary Eruption.—Miliary eruption, sudaminous in character, is found in most cases and is not significant. Often the sudamince are most abundant after the profuse perspiration following a decided fall of tem- perature, and are therefore favorable. Bedsores.—Bedsores are not frequent and as a rule are evidences of faulty or insufficient nursing. In occasional cases their formation can- not be prevented; this* is true of those with deep invasion of the sen- sorium, frequent involuntary discharges of feces and urine, and at times myelitis. When bedsores are a late complication they heal as a rule but slowly, may cause some fever and other constitutional symptoms. When early they are usually an expression of deep infection or lack of resist- ance, and do not argue in favor of a mild typhoid. Bedsores with deep bone involvement are ominous. Abscesses.—Abscesses of the skin, superficial or deep in the subcu- taneous connective tissue, are late complications, and simply retard re- covery, without interfering with full recovery unless an expression of pyemia or other constitutional or mixed infection. When one of the lat- ter complications has caused multiple abscesses, the prognosis remains clouded for days at a time; in most cases recovery is slow, but many die for want of resistance and because of the deep infection. Alopecia and Atrophic Changes.—The lesions referable to the nails and hair are late manifestations without prognostic significance. Alo- pecia and atrophic changes are rarely permanent, and mend slowly after several months. Purpura Hemorrhagica.—Purpura hemorrhagica with skin lesions— macules or large ecchymoses—occasionally arises during the period of convalescence. Hemorrhages from one or many mucous surfaces may re- duce and deplete the patient. Hematuria, intestinal bleeding, severe epis- taxis, and bleeding through the external auditory canal are frequent ac- companiments of typhoid purpura. The prognosis in most of these cases is good in spite of extreme anemia and weakness. Recovery is very slow. Simple purpura hemorrhagica should not be mistaken for the bleeding and cutaneous lesions due to malignant endocarditis—hemorrhagic infarct— which offers a grave prognosis, as do those forms of cutaneous and other BACTERIAL DISEASES 107 internal hemorrhages complicating typhoid, due to deep blood changes, disorganization, septic conditions and pernicious toxemia. All hemor- rhagic lesions of the skin influence prognosis, and demand serious consid- eration. When purpura or any hemorrhagic cutaneous lesion is due to nephritis, either acute or chronic, the prognosis in most cases is bad. Erysipelas.—Erysipelas, an occasional early or late secondary infection of the skin is, when complicated with deep meningeal symptoms, serious— more serious when early. Limited erysipelatous blushes, without marked constitutional disturbances are not of great prognostic significance. Phlegmons depend, in their importance for prognosis, on location, ex- tent, the severity of the associated symptoms, time of occurrence, and other accompanying lesions. The Spleen Enlargement of the spleen, which is present in 90 per cent of typhoid cases, offers but few data which are of use in prognosis; its diagnostic value is much more important. The spleen often decreases in size after severe intestinal hemorrhages. Sudden decrease in the size of spleen after hemorrhage is evidence of marked depletion and is ominous. The size of the spleen hears no relation to the severity of the infection. The spleen recedes as the disease spends its force. So long as the spleen remains enlarged the disease has not run its course. Enlarged spleen persisting without fever, does not justify the conclusion that the patient is free from the possibility of relapse. I called attention to the serious nature of rupture of the spleen in con- nection with the. consideration of peritonitis as a complication. Complications causing changes in the enlarged spleen are compara- tively rare. In 577 autopsies of typhoid patients made by Curschmann at Hamburg and Leipzig, he found the following changes in the spleen:— Infarct and hemorrhage 25 times Abscess 4 “ Rupture 2 “ Perisplenitis 16 “ The Genito-Urinary Organs During the febrile period of typhoid fever the urine is reduced in quantity and concentrated, as in all acute infections. The increased intake of fluids is not likely to have a marked influence on the quantity secreted at the height of the disease. Typhoids who during the febrile period secrete satisfactory quantities of urine may be said to add a favorable fac- tor to the symptom complex. During convalescence there is often a de- cided increase in the quantity secreted, and this is favorable. Urea and uric acid loss, increased during the active period of the dis- 108 SPECIFIC INFECTIOUS DISEASES ease, is lowered as the patient improves and returns to normal during con- valescence. Severe cases show the presence of leucin and tyrosin, though Frerichs and Stadler claim these are present in all cases. Return of normal chlorid excretion reduced during the height of the disease, is favorable and is found early during convalescence. Albuminuria.—The albuminuria of typhoid fever may be either: 1. Febrile Albuminuria 2. Albuminuria of Nephritis 3. Albuminuria due to other complications 1. Febrile Albuminuria.—If all cases are cautiously followed albu- minuria will be found in at least 50 per cent; in most of these it has no influence on the course of the disease. In some, however, it is of great importance. In all cases the presence of albumin demands scientific dif- ferentiation, that its prognostic significance may be fully determined. Those cases in which febrile albuminuria is of grave import show its presence early; in these it is likely to persist, and the quantity large. Almost 30 per cent of these die, as against 10 per cent—the average mortality of the disease. Cursclnnann places the mortality at 25 per cent. Mere traces of albumin without other symptoms are to be numbered among the benign febrile albuminurias. Febrile albuminuria which develops toward the end of the febrile period is serious and demands close inspection to determine its cause. Febrile albuminuria may disappear, to reappear later, and is likely to accompany exacerbation of other symptoms. The microscopic picture of febrile albuminuria ought to include only feiv hyaline casts—no others— uric acid crystals, urates, few squamous epithelia and white blood-corpus- cles. If there are many hyaline casts and other elements, i. e., renal epi- thelia are increased, the prognosis is influenced thereby, and in all likeli- hood there are organic changes in kidney substance. Urobilinuria with febrile albuminuria is suggestive of liver changes. There has been so far as we could find in our cases, no relation between indicanuria and the severity of these cases of febrile albuminuria; the presence of indican is not to be considered dangerous. 2. The Albuminuria of Nephritis.—It is often impossible to dif- ferentiate febrile albuminuria from that of nephritis in typhoid fever. It has been my experience that acute nephritis is not a frequent complication of the disease. Curschmann reports its presence in 4.87 per cent. Gubler and Fobin originally described a symptom complex which is now characterized as nephrotyphoid, in which the symptoms, more particu- larly the urinary picture, of acute parenchymatous nephritis are in the ascendancy. These cases during their early history are often mistaken for uncom- plicated neph ritis, but they are not as a rule difficult of recognition. They BACTERIAL DISEASES 109 are not all serious, and most do not develop uremic symptoms, though occa- sionally patients have died of nephrotyphoid with profound uremia, but as a rule, without the usual edema of acute nephritis. My experience with typhoids in which the diagnosis of nephrotyphoid was justified, has been favorable. Four cases seen during the past 20 years all recovered. In most of these cases the urine is more or less bloody. There are a number of recorded cases (Immerman) in which death resulted with the full com- plement of symptoms of nephritis, hemorrhagic and non-hemorrhagic, at the height of the typhoid process. In the majority of such cases the urine is red, bloody, contains large quantities of albumin, many casts (granular, hyalin and blood), abundant red blood corpuscles, and epithelia. These cases are further characterized by deep involvement of the sen- sorium, and by the presence of but few or no abdominal symptoms of ty- phoid. It is not wise to consider these cases other than the usual typhoid infection, in which there is parenchymatous degeneration of kidney sub- stance, in which, however, the symptoms of such change for a time at least, are decidedly in the foreground. Whatever the symptoms, whenever typhoid fever is complicated by an acute parenchymatous nephritis, it adds an enormous element of danger, clouds the prognosis, and it may be as- sumed that the nephritis is a part of a profound toxemia; never an inde- pendent disease. Death follows in between 40 and 50 per cent of typhoid nephritides during the second week, with all of the symptoms of deep infec- tion. These patients do not as a rule become uremic. The larger number of fatal nephritides which I have seen complicating typhoid have been positively hemorrhagic. When they recover there is not likely to be any remnant of nephritis, as is customary after scarlatinal nephritis. Hemorrhagic infarct of the kidney associated with typhoid from what- ever cause (endocarditic, embolic, thrombotic), is always a grave disturb- ance. In children the result of painstaking examination of urines has demon- strated the fact that a limited number of red blood-corpuscles is normally present in the urine, and further, that albuminuria is not so frequent as in the adult—all of which adds to the factors which make the prognosis of typhoid in children favorable. Postfebrile nephritis is not frequent; most cases which I have seen finally recovered or became latent. Occasionally patients have developed, after several months of albuminuria with casts, general dropsy and heart complications, and have died either of uremia or with symptoms of dilated and worn-out heart. 3. Albuminuria Due to Other Compeications.—Cystitis is a cause of albuminuria; it may prove annoying but does not of itself threaten life. Typhoid bacilli are present in the urines of all typhoid patients in large numbers (one hundred million in a single cubic centimeter) a fact 110 SPECIFIC INFECTIOUS DISEASES which adds an element to be seriously considered in prophylaxis and in prognosis. Pyelitis is rare, though Schottmiiller calls attention to its occurrence, and in his case found typhoid bacilli in the urine months after full re- covery. Albuminuria may be present with many complications of typhoid, such as pneumonia, pleurisy, empyema, meningitis, otitis, erysipelas, kidney abscess and other conditions in which its prognostic significance must of necessity depend largely upon many factors, most of which have been con- sidered in this chapter. Neither the Elirlicli diazo-reaction nor the more recently considered Russo reaction to methylene blue have much bearing on prognosis. The former is found in 90 to 100 per cent of typhoids, the value of the latter is still sub judice; our figures are not yet sufficiently reliable to justify consideration. I am satisfied that for diagnostic purposes it will never displace the Ehrlich test. It would seem that serious cases as they im- prove, often lose the diazo-reaction. Genken holds that the reaction is coin- cident with the period of Eberth bacteremia, the appearance of the bacilli in the blood, and that it is lost as these disappear. With relapses the reac- tion returns if due to Eberth bacteremia, not if due to other complications; hence under these conditions it is of diagnostic and prognostic value. It must not be forgotten in considering the significance of the Ehrlich diazo-reaction that it is present with acute miliary tuberculosis, cerebro- spinal meningitis, lobar pneumonia and measles. Orchitis.—Orchitis, a late complication of but few cases, ends in full recovery and usually without suppuration. Menstruation.—-Menstruation during the course of the fever has been present in the majority of cases but once, and has occasionally been pre- mature, without influencing the symptoms so far as I could judge. Menses usually appear when due during the first 10 to 14 days of the disease, not as a rule, when due later, until some time after the period of convalescence has been fully established, and they are then without untoward results to the patient. Menstrual anomalies following typhoid need not disturb the patient; the flow will, after a reasonable, time, return to its previous regu- larity. Acute suppuration of the vulvovaginal gland, catarrhal conditions of the genitals, moderate local edema, decubitus, i. e., vaginal ulcers, only prolong convalescence, without threatening the patient. Gangrene of the Vulva.—Gangrene of the vulva I have never met in my practice. Spillman and others, Hoffman and Liebermeister included, have reported cases and consider the complication fatal as a rule. Pregnancy.—Pregnancy, as already mentioned early in the chapter, adds to the dangers of typhoid infection. A large proportion of pregnant women abort (46 to 56 per cent), usually during the second week of the disease, though this accident may happen later. Once beyond the febrile BACTERIAL DISEASES 111 period, the chances are against miscarriage. Murchison considered the prognosis of the pregnant woman with typhoid as very serious. Most authorities who have recorded their experiences place the mortality be- tween 8 and 16 per cent. The Nervous System There are hut few cases of typhoid which run their course without symptoms referable to either the 1. Central nervous system, or 2. Peripheral nervous system. 1. Central Nervous System.—The hearing of symptoms referable to the central nervous system on prognosis is exceedingly important. The forecast is less favorable in direct proportion to the depth of cerebral inva- sion■, as shown by positive symptoms and by lumbar puncture. The prog- nosis is particularly had when in adults, full-blooded and previously healthy, these cerebral symptoms persist. Liebermeister places the mor- tality of these cases at 70 per cent. There is a class of cases which has been characterized as meningotyphoid, meningismus typhosus, in which the early symptoms are those of meningitis, the typhoid manifestations appearing later. These patients may present all of the appearances of fully developed meningitis, including the Kernig symptom, opisthotonos, vomiting, hyperesthesia, and wild delirium at times, sometimes low mutter- ing delirium. As a rule these symptoms clear with the appearance of a train of continuous typhoid manifestations. Persistence or increase of these evidences of deep cerebral (meningeal) invasion must be interpreted as signifying a serious condition. In children, meningismus typhosus is more frequent than in the adult and is less serious. Cerebral manifestations are most likely to be present and characteristic in moderately severe cases with the beginning of the second week. The so- called typhoid condition gives a clue to the severity of the individual case. Wild delirium at night beginning in the second week, repeated during the day at intervals, with more or less rigidity, exalted reflexes, dry tongue, sordes, high fever, correspondingly rapid pulse, retention of urine, Kernig symptom, mind clouded, with characteristics in the lumbar fluid of puru- lent meningitis, with or without typhoid bacilli, is a complex of symptoms of enormous gravity, but not absolutely hopeless. Alcoholics, with symptoms of wet brain, alcoholic meningitis, with active delirium, always justify a grave prognosis. Involuntary discharges of urine and feces are symptoms of the more serious typhoids. The temperature in cases of serious cerebral invasion is not necessarily high; in some it is but slightly elevated and these often drag a long and monotonous course during many weeks before the sensorium is entirely clear, while occasionally they lead to psychoses, which require attention 112 SPECIFIC INFECTIOUS DISEASES during many months. More serious and permanent mental disturbance may finally develop. Active, persistent subsultus tendinum is an expression of the more serious types of the disease; as is picking at the bed-clothes and imaginary objects. Convulsions, in very young children, are occasionally an early symp- tom in cases with high temperature or in those of neuropathic habit, but are not of serious import as a rule. Improvement or moderate control of nervous symptoms by baths and other treatment is always a reassuring experience. Psychoses when pres- ent during the febrile period are likely to disappear early during convales- cence and as a rule do not return. In some cases delusions, hallucinations, illusions, or obsessions persist long after convalescence. In some there are finally developed a true circular insanity, manic depressive psychoses, while in others, fortunately not often, obstinate depression, from which after long periods most patients recover (65 per cent). The length of time during which these postpyrexial psychoses persist in favorable cases varies. It is impossible to set a time limit. My cases have averaged between 6 and 9 months. An occasional case ends in permanent insanity ; here family history is of paramount importance. When hysteria develops after typhoid it is not to be regarded seriously—prompt treatment leads to satisfactory results. This is also true of all types of neurasthenia. I have seen several eases followed by multiple cerebrospinal sclerosis, in which the disease was progressive, following its typical course. Posttyphoid myelitis offers nothing favorable. Acute ascending paralysis, when complicating typhoid, will, as a rule, promptly lead to death because of respiratory involvement. Reflexes.—Curschmann reports the behavior of the reflexes as fol- lows: In severe typhoids, where the patients are much reduced, usually toward the end of the febrile period or during convalescence, there is de- cided increase of the patella tendon reflex, and marked ankle clonus. In cases of moderate severity the patella tendon reflex may be absent, normal, or oftener, feeble. Toward the end of the disease and during convalescence in these cases, he found moderate increase of the reflex. In children the reflex was more often absent or materially reduced. 2. Peripheral Nervous System.—Multiple neuritis and peripheral pa- ralyses occasionally complicate typhoid fever. There are inflammatory changes in single nerves which may leave lasting symptoms—optic neuri- tis, auditory neuritis, and the so-called cerebral monoplegia, which is prob- ably peripheral neuritis. The prognosis of most peripheral neuritides is good; multiple neuritis leads to a protracted period of symptoms but, as a rule, to fair use of all of the extremities. The so-called typhoid spine, painful during long periods, as a rule leads BACTERIAL DISEASES 113 to a gradual full recovery, as does also typhoid spondylitis and perispondy- litis. The Muscular System The muscular system offers, aside from its enormous atrophy, nothing of prognostic value; time returns the skeletal muscles to their normal conditions. Grave atrophic and hypertrophic changes of organic origin are rare. The Osseous System The lesions referable to the osseous system are not infrequent. They belong to the. domain of surgery and as a rule, under proper treatment there is full recovery, even when many bones are involved in necrosis or caries. The Ear Complications referable to the auditory apparatus are frequent. Bezold found these in 4 per cent of typhoids. They include changes in the external ear, such as gangrene, superficial skin lesions, decubitus, periosti- tis and furunculosis, none of which are of themselves threatening. The affections of the inner ear may be functional or organic. But few cases of typhoid fever at the height of the disease, retain normal hearing; it is most blunted with the more serious cerebral complications, when it is a part of the general toxemia. Most cases in which the. changed hearing is due to functional disturbance, offer a good prognosis. Otitis media, when uncomplicated, is promptly relieved by puncture of the drum membrane, and as a rule makes an uninterrupted recovery. Neg- lected cases, those associated with deep infection and brain symptoms, periostitis, mastoid invasion, sinus thrombosis, and caries are often serious, though the more serious complications of otitis media suppurativa are not as frequent with typhoid as with scarlet fever, diphtheria and pyemic infections. For the good of all typhoid patients it is always wise to exam- ine the ears from time to time, that pus accumulations or otitis media may be promptly detected. This should be done by an expert: it may in occa- sional cases prevent serious complications, among these pyogenic meningi- tis. Labyrinthine disturbances are rare. When they persist they may lead to Meniere’s complex with defective hearing. Eye Complications There are but few cases in which eye symptoms or complications dur- ing the active period of the disease, cause anxiety or influence the course of the disease; these complications are less frequent than with other serious 114 SPECIFIC INFECTIOUS DISEASES infections. The paralysis of the abducens or motor oculi, or optic neuritis, amaurosis, are late manifestations which belong in the field of ophthal- mology, and are not connected with the serious manifestations considered in the prognosis of the typhoid process itself. For their consideration and significance, it is always safest to consult the eye specialist. My experience with relapses—and these are veritable fresh infections —has been almost uniformly favorable. It is a rule that relapses are not so severe as the original infection. It is rare to lose a patient during an uncomplicated relapse, and these are less liable to complications than are initial infections. In my own experience I have found relapses in 8 per cent of all cases. Relapse The prognosis of those cases of typhoid without intestinal lesions which we meet occasionally, to which Eberth, Elexner, and Horton-Smith have called attention should be as cautiously made as that of typical typhoid. In the former we are dealing with a typhohacteremia, and it need not sur- prise the clinician to find some of these with profound septic symptoms, for they are due to mixed infection. Some were found with streptococcus, others with pneumococcus, and Lenhartz has reported a case of typhoid with staphylococcus aureus infection. All of these types make prognosis grave in accordance with the associated toxemia as expressed by heart, brain, lung and kidney symptoms. Typhoid Without Intestinal Lesions Causes of Death A thorough consideration of available and reliable post mortem find- ings proves that in 17.7 per cent of typhoid autopsies no complications were found, and death was due to toxemia. If we add to these the number of deaths (6.2 per cent) in which post mortem search showed but insignificant complications, the patients dying either in the first, second or third weeks of the disease, we find therefore 24 per cent (17.7 per cent and 6.2 per cent) in which typhoid toxemia may he considered to he the cause of death. Striimpell’s statement is therefore justified: “In only a relatively small proportion of cases have I found death due to general infection in typhoid fever. The majority (76 per cent) of deaths are due to complications uninfluenced by treatment, and not dependent directly upon the constitu- tional infection.” Complications which were the causes of death in 5 per cent and over of the autopsied cases (Holscher) may be classified as follows: BACTERIAL DISEASES 115 Pulmonary edema 15 per cent Myocardial degeneration (fatty and parenchymatous).. 13 “ “ Parenchymatous and fatty degeneration of the liver.. 10 “ u Bronchitis 10 11 “ Lobular pneumonia 8 “ “ Croupous pneumonia 7 “ “ Pulmonary infarct 6 “ “ Intestinal perforation with peritonitis 6 “ “ Intestinal hemorrhage 5 “ “ Edema of the brain 5 “ u Decubitus 5 “ “ The changes associated with typhoid fever are far-reaching and may invade any organ of the body. A study of the preceding pages will show that the alimentary tract from the tongue to the rectum, the parotid, pan- creas, liver, mesenteric glands, veins, arteries, heart, respiratory organs, the blood, the muscular system, the central and peripheral nervous sys- tems, the skin, and the connective and bone tissue may be the seat of pathologic change; in truth, no organ of the body is immune and many may be involved at the same time. For all of these reasons it may be posi- tively asserted that in no disease should the prognosis be more guardedly given and all that the individual case presents be more cautiously weighed. Deaths from the Sequelae of Typhoid Fever From the reports of the visiting nurse service of the Metropolitan Life Insurance Company as reported by Dublin, in a study of 1,936 cases of typhoid fever recorded in 1911, the following interesting features were established. The number of cases above mentioned include 362 which were finally eliminated from consideration because the diagnosis was not considered to be accurately established. The remaining 1,574 cases make clear the effect of typhoid fever on vitality during the first three years following recovery. It was found that 146 died while under treatment—a death rate of 9.28 per hundred. The principal complications in fatal cases were intes- tinal perforation, hemorrhage, meningitis, pneumonia and heart involve- ment. “To determine the effect of the disease on vitality for the three years following the attack, it was necessary to compare the actual mortality of the 1,428 survivors with the expected mortality among the same class of persons. This was done by distributing the 1,428 cases by sex, color and 10-year age period, and by comparing them with similar groups taken from the mortality tables of the company for the same years. In other words, the mortality was not an arbitrary measure, but gave the death 116 SPECIFIC INFECTIOUS DISEASES rate which persons of the same age, sex and color among the policy holders had experienced for the same years. “From such comparisons, it was found that in the series of 1,428 per- sons the expected number of deaths was 26.45, whereas, the actual number that occurred was 54, the conclusion being that during the first three years after recovery from typhoid fever, the mortality is twice the normal. This increased rate, however, was not uniform for all three years, being greatest during the first year following recovery, less during the second year, and still less the third.” Of the 54 deaths, tuberculosis caused 39 per cent, and diseases of the heart 14.8 per cent. Dublin concludes that in the United States there are 8,000 deaths annually among those who have recovered from typhoid fever and who yield to disease because of their reduced resistance during two years fol- lowing recovery.

Typhus Fever {Spotted Fever, Typhus exanthem aticus, Famine Fever {of Ireland), Jail Fever, Camp Fever, Ship Fever, Brill’s Disease, Mexican tabardillo) History.—Typhus fever was first brought to America in 1812. The credit of having separated typhus from typhoid, thus making differentia- tion possible belongs to American Medicine, directly to Gerhardt of Phila- delphia in 1836. Jenner also insisted on typhus fever as a clinical entity separate from typhoid or enteric fever. Plotz, a young bacteriologist, has recently established the true cause of typhus fever. His investigations were made in the Pathological Labora- tory of Mt. Sinai Hospital in Hew York City, and the results were pres- ented to the profession in a “Preliminary Communication” on “The Eti- ology of Typhus fever (and Brill’s Disease)” which appeared in the Jour- nal of the American Medical Association May 16, 1914. In his original report he claims to have found the same organism in five of six cases of Brill’s disease by the use of anaerobic methods. A large number of con- trol cases were studied and the “organism was absent from each.” The bacillus is pleomorphic, “from 0.9 to 1.93 microns in length, the breadth being from one-fifth to three-fifths of the length.” It is Gram-positive, not acid-fast, has no capsule, “and polar bodies can be demonstrated with ap- propriate methods,” and it grows only anaerobically. In a private communication from Plotz (bearing date of May tenth, 118 SPECIFIC INFECTIOUS DISEASES 1915,) he says: “By means of an anaerobic method of blood culture, a bacillus was isolated in pure culture from seven cases of European epi- demic typhus fever, or one hundred per cent of the cases studied during the febrile period. With the same method the identical organism was recovered during the febrile period of the. local endemic form of the dis- ease in eighteen of thirty-four cases, or 53 per cent, and in two additional cases taken after the crisis similar blood cultures made in one-hundred and ninety-eight control cases yielded no such organism.” “Serological studies were carried on by Doctor Peter K. Olitsky, who has demonstrated the presence of immune bodies mostly in the apyrexial period” . . . “the same immune bodies have been demonstrated in mon- keys who recovered from the disease.” In guinea-pigs and monkeys who were inoculated and developed the disease the organism was recovered; the greatest bacteriemia has been found to occur early in the disease, when the temperature is highest. The pure culture of the organism can produce typical typhus fever in the guinea-pig.” Plotz has demonstrated that typhus blood without bacilli or but few, is non-infective for animals. “It seems that infectivity is absolutely dependent upon the presence of a suf- ficient number of these bacilli.” The discovery of the bacillus by Plotz and the elaboration of a vaccine promises to prove of enormous prognostic and prophylactic value, for it is reasonable to expect that with modern methods of cleanliness, the destruc- tion of the carrier—the body louse, from man to man—and compulsory vaccination against the disease among the belligerents, the same success will follow which we have had with the typhoid vaccine in our army. The recent consideration of the “Etiology of Typhus Fever and the Methods of its Prevention” by Anderson strengthens the conclusions given in the preceding paragraph. He insists that “the reduction of lice infesta- tion among the population in general,” “the destruction of all lice and their eggs found on the bodies, clothing, bedding and surroundings of all cases of typhus, typhus suspects and contacts” is absolutely necessary, and will eliminate the disease because the louse is unable to transfer itself to great distances.” “The history of typhus is written in those dark pages of the world’s history which tell of the grievous visitation of war, famine and misery of every kind” (Hirsch)—a frequent hut justified quotation. With positive bacteriologic data, we can more easily explain the ac- cepted conclusion that the disease reproduces itself “in the immediate sur- roundings of the patient sometimes before and after, as well as during, the febrile period” (Moore). The louse is carried on the body, clothing or other fabrics, furniture, more particularly woolly substances and furs. The contagium continues its vitality for months. With improved sanitary conditions in jails, in the army, on shipboard; BACTERIAL DISEASES 119 with better care of the masses in large cities, in tenements; with less filth, epidemic typhus fever, in civilized countries and sanitary communities has become exceedingly rare. In our own country we have had no alarming epidemic to report in over half a century, and the isolated cases which are occasionally brought to us are of a milder character than those seen over fifty years ago. In 1881 there was a small epidemic in ISTew York of which a large number (-|) were incorrectly diagnosed. There was a time when one-half of all physicians in Ireland attending cases of typhus, fell victims to the disease. In an epidemic about the middle of the nineteenth century, six of thirty-two (6 of 32) physicians at Bellevue Hospital in Hew York died of the disease. The number of physicians attacked during epidemics is larger than with any other single acute infection. The young, active, and mentally alert, are most likely to develop typhus during times of epidemics. One attack gives complete immunity. Typhus fever must always be considered a serious disease. The mortality ranges between 15 and 20 per cent in times of epidemics. Hot so however in milder cases of so-called Brill's disease* which, if search is made and care in diagnosis is practiced, will be found to be comparatively frequent. In 500 uncompli- cated cases ending in recovery, the average duration was 13.43 days; of 100 fatal cases, 14.6 days. Patients who live beyond the 20th day and die, yield to complications rather than to typhus itself (Murchison). Death is likely to follow during the second week. Foudroyant cases, beginning with fiery symptoms, so-called “sthenic fever” with full tense pulse which soon weakens, high fever, flushed ma- hogany-colored face, delirium, coma, Kernig symptom, great restlessness, opisthotonos, mottled skin, hemorrhagic eruption, involuntary stools, (though some patients may often be constipated), suppressed or materially reduced urine with evidences of nephritis or febrile albuminuria, are fatal usually during the first week. The Pulse.—The prognosis in those who have been previously reduced by illness or without resistance, is bad, and is the same in the aged. The pulse offers valuable data for prognosis. With persistent rapidity and high tfever, intermission or irregularity, pulsus alternans, with or without hur- ried respiration, the outlook is grave. When respiration is hurried, either due to myocardial weakness, secondary pulmonary engorgement, dissemi- nated bronchitis or pneumonia—catarrhal or lobar—the prognosis is cor- respondingly worse. Persistently slow pulse during limited periods after the fever has subsided is not unfavorable. The Blood.—The blood in unfavorable cases promptly shows a marked reduction of red blood corpuscles with a corresponding reduction of hemo- globin. Average cases of typhus show moderate leukocytosis—12,000 to 15,000 * See last section of this article. 120 SPECIFIC INFECTIOUS DISEASES though variations have been reported Hanging between 1,600 to 17,600 (Krause). The low counts, i. e., marked leukopenia are unfavorable. Port in three cases on the third day found leukocytic counts of 7,900, 8,100, 14,700, respectively. He found an increase of small lymphocytes, neutro- philic polymorphonuclears 60 per cent, small lymphocytes 30 per cent, large lymphocytes 3-7.5 per cent, eosinophils 1 per cent and mast-cells not above 0.5 per cent. According to Goldberg and Anderson satisfactory evi- dence has not yet been adduced that the blood of the monkeys infected with typhus is virulent in the prefebrile stage and, second, it is positive that the blood of the monkey may still be virulent 24 to 36 hours after the return of the temperature to normal. In favorable cases improvement should be apparent about the middle of the second week. The Urine.—Diazo-reaction is present in over 50 per cent of typhus urines and is of no prognostic value. Nephritis—parenchymatous, partic- ularly w?hen hemorrhagic—adds a serious complication. Alcoholics, early fall into a “typhoid condition” with deep invasion of the brain, marked evidences of such complication in delirium and lung invasion, when death is the usual result. Symptoms.—The gravest cases are those with symptoms of meningitis, “coma vigil” of Jenner, pin point pupils, hemorrhagic eruption, suppres- sion of urine with albumin and casts in the urine voided, myocardial weak- ness with feeble embryonic sounds, and pulmonary inflammation or con- gestion and meteorism. Persistent vomiting with hiccough is unfavorable. Vomiting early in most cases is controllable; 80 per cent of typhus patients are sufficiently nourished and are carried safely to recovery without serious incidents. Reduction in the size of the spleen—uniformly enlarged in typhus—is always favo7'able. Almost all cases have more or less catarrhal bronchitis, which does not, unless it leads to further infection, reduce the patient’s chances. The addition of bronchopneumonia, lobar pneumonia, empyema, endo- or pericarditis, hemorrhagic infarct or nephritis (hemorrhagic), the lat- ter, already mentioned, plunge the patient into a serious condition and naturally reduce the chances of recovery very materially. Profuse perspiration is mentioned as an unfavorable symptom by some when it persists after the tenth to the twelfth day. Peripheral neuritis, a painful and occasional sequel, usually yields after a long period. Relapses do not frequently follow typhus fever. Brill's Disease So-called Brill’s disease is now known to be a mild form of typhus fever. This type of the disease runs its course in from twelve to fourteen BACTEEIAL DISEASES 121 days, and terminates by crisis; convalescence is rapid. The mortality is below 1 per cent and it is most prevalent during the autumn months.. Anderson and Goklberger working in Mexico City have proved the identity of Brill’s disease and the typhus (tabardillo ) of Mexico. They inoculated monkeys successfully, and bel icve that the body louse carries the infection; indeed the monkeys were infected through the louse. The relationship of Brill’s disease in New York and typhus of Mexico was further established beyond peradventure by the experiments of these investigators, for they succeeded with the blood of Brill’s disease (three patients in New York furnishing this), in carrying the infection through eleven generations of monkeys. These results are in line with those of Plotz, Baehr and Olitsky. The prophylactic and prognostic value of these, positive conclusions is of inestimable value and is “far-reaching.” The experiments further proved that one attack produced lasting immunity. Sanitarians must rec- ognize the fact that these milder types of typhus may lead, through care- lessness and failure to recognize them, to endemics and epidemics of the disease, virulent or non-virulent.

Paratyphoid Disease Paratyphoid fever or disease includes all organic changes which are produced by infection with paratyphoid bacilli associated with bacteremia, occasionally wTith sepsis. The organic diseases which are thus produced may include enteritis, pyelitis, endometritis, cholecystitis, and meningitis ( Schottmiiller). Achard and Bensaud called attention to the presence of bacilli in the pus of joints and in the urine of a typhoid patient which presented all of the characteristics of paratyphoid bacillus B. in culture media ; and named the infection paratyphoidique. To Schottmiiller belongs the credit of demonstrating in 1900 the existence of the clinical entity paratyphoid, and 122 SPECIFIC INFECTIOUS DISEASES of tracing its origin to bacilli which admitted of positive differentiation. The clinician will continue anxious only until he has proved by bacterio- logical means the characteristics of the disease-producing bacilli, thus estab- lishing the positive diagnosis. The diagnosis may be strongly suspected without the more painstaking and exact methods, but it cannot be fully established. Once the diagnosis is made positive a favorable, prognosis may be given and full recovery expected after a period of varying symptoms with irregu- lar temperatures and convalescence, which is long and out of proportion to the benign nature of the disease. The mortality is not above 1 per cent, though Lorrain Smith reports 6 deaths in 162 cases. This mortality is much above that of our cases in New York State and those reported by continental observers. There are two types of paratyphoid bacilli which interest us—A and B. The latter is the cause of the disease in 80 per cent of cases. In con- sidering the conditions which may be produced by the introduction of the B bacillus, we include those cases of meat poisoning formerly considered to be due to the Bacillus enteritidis of Gartner, which we now know is identical with paratyphoid bacillus B. While it is not within the province of this work to consider bacterio- logic methods, I add the following that prognostic conclusions may rest on safe methods of diagnosis, and that errors in differentiation may be avoided:— Paratyphoid bacilli are actively motile, with side movements; the size of the typhoid bacillus; not colored by Gram. Grows as an anaerobic bacillus on all culture media. Bouillon is diffusely turbid, with a thin scum on its surface. On gelatin the growth causes a blue wl\ite opaque deposit. The isolated colonies are coarser than the typhoid culture, button-shaped and not fissured. On agar the deposit is thin, white, gray and translucent, with characteristic gas bubbles. On potato a grayish brown thick deposit, much like that produced by the coli communis bacillus. Milk is not curdled, finally becomes clear and translucent; is not fermented. In Drigalski, Conrad media (litmus milk-sugar, sodium bicarbonate, strong bouillon nutrose, and a small quantity of crystal violet B (Hoechst) deep blue colonies are grown. Indol formation is absent in cultures not older than 1 week. Milk- and cane-sugar are not fermented; grape-sugar is made to ferment in the presence of colonies of paratyphoid bacilli—one of the most important diag- nostic features. Typhoid bacilli do not form gas in the presence of grape-sugar; the coli group do ferment milk- and cane-sugar. Paratyphoid inoculation is highly fatal to small animals (mice, rats, etc.). In litmus whey, B produces an alkali, and type A an acid. Agglutination continues in much stronger dilution than do typhoid bacilli, when the latter are no longer influenced. Thus Libman reports a case in which the serum agglutinated the paratyphoid bacillus B at 1 to 50, and the typhoid BACTERIAL DISEASES 123 bacillus at 1 to 250. There is a diazo-reaction in 20 to 30 per cent of cases. Bacterial investigation of the blood and stools offers the safest method of reaching correct diagnostic conclusions. Pregnancy invites invasion of the genito-urinary tract in the presence of paratyphoid, infection. The disease is met oftener during the summer than winter; the epi- demics arise suddenly, many infected from the same source fall ill at the same time—transmission from patient direct is rare. Paratyphoid dis- ease differs from typhoid in the rarity of transmission from the patient* direct. Infections due to meat or other articles of food may present active and distressing symptoms early. The more severe cases are those in which there is obstinate nausea, vomiting, hiccough and weakening diarrhea. These cases begin to mend after a few days but recover strength slowly. The spleen offers no prognostic data; is uniformly enlarged. The blood picture is practically the same as in typhoid fever. There is an early leukocytosis, then the characteristic leukopenia, disappearance of eosinophils, to return as the patient improves. With far-reaching enteritis there may be persistent leukocytosis. These data are of some prognostic value. The skin lesions, urticaria, scarlatinal eruption, with desquamation are not unfavorable. Hemorrhagic lesions of the skin and mucous membranes are found among some of the few cases which end fatally. Loss of flesh is striking. Intestinal hemorrhage occasionally complicates paratyphoid (3 to 5 per cent), and is not as significant as in enteric fever. Albuminuria is present in most cases, is moderate, without the usual accompaniments of nephritis, though the latter has complicated some cases. The urine is markedly reduced in serious cases in which vomiting and diarrhea are excessive; complete anuria during limited periods has been alarming. High specific gravity with albumin, pus corpuscles, blood, casts and epithelia have been present in some of these cases. In unfavorable cases the temperature may, before death, drop to 1° to 3° below normal. Furunculosis and distant infections, joint invasion, rarely osteitis, orchitis, otitis, liver inflammation, cholecystitis—all due to the paraty- phoid bacillus—have been met. Relapses may be expected in from 8 to 12 per cent of all cases. Most fatal cases die early, usually between the third and fifth days, with rapid small thready pulse, distant heart sounds, cold extremities, some cyanosis, great thirst, subnormal temperature, and respiratory paralysis. Schottm,filler calls attention to the fact that patients suffering from chronic ailments are prone to develop a chronic form of gastro-enteritis 124 SPECIFIC INFECTIOUS DISEASES dependent on paratyphoid infection. Most deaths are due to the severity of the primary infection or to secondary lesions which the patients are unable to withstand because of reduced resistance. The prognosis of the abdominal type of the disease is almost uniformly favorable, as is also the invasion of the bladder and the kidney pelvis. Cases of puerperal paratyphoid which have been fatal, were of a mixed type with streptococcus infection. I have never seen a case in which the cholecystitic type of the disease has occurred—if I have, it has not been recognized. Schottmiiller has reported cases in children who died of paratyphoid meningitis. Complications may include many of those described in the chapter on Typhoid Fever and it is to he remembered that paratyphoid infection may follow or be associated with other acute and chronic infec- tions,, including pure typhoid bacteremia.

Influenza {Epidemic Catarrh, La Grippe, Febris epidemica) Influenza is a disease of protean character, panepidemic, acute, due tc the Bacillus of Pfeiffer (1892) which by predilection attacks the respira- tory mucous membranes, is characterized by fever, marked depression, exhaustion and weakness, and is prone to give a fresh impetus to latent diseases, particularly of tuberculous nature and circulatory disturbances, while it is often followed, particularly in those of neuropathic tendencies, by long periods of nervous symptoms. Epidemics may recur at intervals varying from a few (4 to 5) to one hundred years (100). There is an authentic account of an epidemic in Italy in 1173 A. D. In 1510 England was visited, and in 1627 the disease was brought to Mas- sachusetts. The disease travels as fast as travel itself, not faster. The last pan- epidemic which visited Europe and America was in 1889-90 when we were introduced to a disease unknown clinically to the profession of both continents. The students of medical history had only a vague concep- tion of influenza, but to none was its clinical history clear, nor were its after effects appreciated until the profession had been taught in the school of experience. BACTERIAL DISEASES 125 The disease is contagious and its period of incubation surprisingly short (2 to 4 days). The mortality of influenza does not exceed 1 per cent, including complications. The average mortality, including those given by continental and American clinicians, is 8 per cent. But few are immune to the disease though nurslings seem to escape, and the aged are attacked in smaller numbers than are the young and active. When the aged were attacked, the mortality usually due to complications, was higher than dur- ing early life. Thus in Prussia, statistics show the number of deaths and ages during years of limited epidemics as follows:— 1904 3,Y96 cases 1905 6,380 “ 1906 2,516 “ 190Y 5,516 “ Of these deaths 2,004 were over Y0 years of age 4,109 between 60 to Y0 years of age 1,190 “ 30 “ 60 “ “ “ 206 “ 15 “ 30 “ “ “ The bacteriology of influenza is fully established. The Bacillus of Pfeiffer is very small, one-third the size of the tubercle bacillus, is dumb-bell shaped, usually single, occasionally in chains by end to end contact; it takes anilin dyes (carbo- fuchsin), is decolored by Gram, the ends stain more than the shaft; it is non- motile; is abundant in the sputum; is the cause of influenza pneumonia, and is often found with other bacteria, mainly pneumococci and streptococci. The leading types of Influenza are: 1. Catarrhal (Respiratory) 2. Gastro-intestinal influenza 3. Influenza of the nervous system 4. Influenzal fever 1. Catarrhal or Respiratory Influenza This is by far the most common form of the disease during epidemics, and when uncomplicated and promptly treated yields within from 3 to 6 days, leaving the patient weak out of all proportion to the duration of the symptoms. The bronchial and nasal catarrh, which is the usual accompaniment in over 90 per cent of all cases, disappears without leaving physical signs or permanent damage. In this as in all types of influenza the enlarged spleen, which is as a rule easily outlined by percussion is of no prognostic value. Moderate albuminuria at the height of the disease is not uncommon without ultimate serious complication, and is not of serious moment. SPECIFIC INFECTIOUS DISEASES 126 Albuminuria in catarrhal cases complicated by pneumonia, with evi- dences of nephritis is not to be ignored or lightly regarded. I have found abortion rare in pregnant women during influenza. The complications most to be feared in the catarrhal type of influenza are referable to the respiratory organs, more particularly the lung (pneu- monia), pleura (pleurisy, etc.) and also the heart. Mixed infection is the leading cause of secondary involvement of vital organs in catarrhal influ- enza, though a large number of pneumonias are due to direct infection with the Pfeiffer bacillus. In no disease does a good prognosis depend more upon rest than in catarrhal influenza, hence the necessity for cooperation of the patient with the physician. Serious complications are thereby re- duced to a minimum and the persistent anomalies referable to the heart are almost uniformly prevented even in the presence of previous weakness. Pneumonia most dreaded of all complications during times of influenza epidemics behaves peculiarly, and is often atypical. During a supposed period of convalescence I have found large areas of lung tissue consolidated with all of the physical signs of such a lesion, with- out marked change in respiration, with slight or no fever, pulse of fair quality, not above 110, and without cough or expectoration. These cases with rest and treatment make a slow but satisfactory recovery; in the aged this complication may be the cause of sudden death. The most serious cases of influenza pneumonia in the United States during the larger epidemic of 1889-90 were those which developed early— due to the Pfeiffer infection—or developed before the end of the first week. In active subjects this was of the lobar—in the old, in the young and in the feeble, of the lobular variety—while in occasional cases there was a mixed form in which both lungs were involved in good sized lobar deposit and islands of broncho-pneumonia. A serious type of pneumonia complicating influenza is the migratory type dependent on mixed (pneumococcus) or on streptococcus infection alone. These cases may lead the clinician to feel secure because of re- peated pseudocrises, when promptly there are evidences of fresh invasion and the disease drags a weary course through several weeks; the majority of such cases die of myocardial degeneration with more or less meningeal symptoms. The pure influenza pneumonia is usually catarrhal (bronchopneu- monia) and offers a good prognosis in children, a fair prognosis during early life (10 to 20 per cent mortality), a better prognosis during the active years of life (6 to 10 per cent in cases treated early), in the aged a very doubtful prognosis (20 to 50 per cent, varying in different epidemics and under varying conditions of health, resistance, etc.). With all pneumonic complications alcoholics are seriously handicapped. Pneumonia with Influenzal Meningitis.—If pneumonia is added to influenzal meningitis, the prognosis is exceedingly grave. In these cases BACTEKIAL DISEASES 127 as in the simple influenza pneumonia, the type is bronchial, in some cases lobar, in others we find the mixed type. In some epidemics the mortality from this combination has been as high as 50 per cent; in others lower, as low as 20 per cent. When meningitis is purulent with pneumonia, a high mortality must be expected (over 80 per cent). Pisek reported his mor- tality as 92 per cent. The majority of all deaths traceable to influenza are due to pneumonia of the catarrhal type (Bronchopneumonia). 118 autopsies made by Hirschfeld on cases of influenza include: 11 cases of croupous pneumonia 8 “ “ mixed (croupons and lobular pneumonia) 24 “ “ catarrhal (lobular) pneumonia Persistent cough, non-tuberculous, continues long after the acute symp- toms in a few cases. These are probably due to a chronic bronchitis or peribronchial change, at times to enlarged bronchial glands (nodes), the latter in children oftener than in the adult, a chronic tracheitis, and should always demand thorough differentiation, for in some tuberculosis is finally unearthed. These cases continue during relatively long periods to give negative reactions and physical signs. The majority of these coughs finally yield, and the patient recovers fully. dSTo acute epidemic disease lights so many latent processes into activity as does catarrhal influenza; among the most frequent of these is pulmonary tuberculosis; usually of infiltrating character, though acute miliary depos- its are not infrequent. The latter run the usual rapid course. This was particularly true of the panepidemic of 1889-90 in the central counties of New York State (For further data, see section on Pulmonary Tubercu- losis). Simple uncomplicated pleurisy, not a frequent accompaniment, offers a good prognosis, as do those cases of empyema which follow pneumonia. The early empyemata do not offer such a favorable prognosis, for they are only a part of acute and serious lung infection (pneumonia). When gangrene of the lung follows pneumonia, the majority die with symptoms of sepsis and exhaustion. Abscess of the lung if detected and relieved by operation, offers a fair chance of recovery. Bronchiectasis may result from one or both of the two preceding com- plications ; if the patients live, the condition continues to be chronic, more or less troublesome according to the size and location of the bronchial dila- tation. Pulse and Heart Changes.—With all the complications of catarrhal influenza the pulse offers the usual prognostic data as in other acute infec- tions. Persistent changes in the pulse and heart which are often more alarm- 128 SPECIFIC INFECTIOUS DISEASES ing to the patient than to the physician, are likely to be late, and may follow any of the types of influenza. The number of cardiac anomalies and arhythmias following the infection is very large; they are dependent on either myocardial weakness or functional disturbances of the heart. Intermittence is present as a rule in these cases; occasionally tachy- cardia alternates with bradycardia or the latter is a postfebrile or post- pneumonic sequel; in all there is an enormous element of neurasthenia. Fear takes possession of the patient. In the larger proportion of cases the heart finally, after a long period, falls into better habits, and returns to normal. Early dicrotism need not be considered of serious nature. In rare cases, probably where the heart muscle was already the seat of some disease, fatty degeneration of the heart muscle with thrombosis in both ventricles has been found post mortem and occasionally gangrene of the lower extremities has developed in these cases (Eichhorst, Gerhardt). Relative mitral insufficiency is an expression of heart weakness which yields to rest in most cases with the disappearance of the systolic murmur. An occasional case develops fatal malignant endocarditis or the less serious type of the disease or, rarely pericarditis. Ear Complications.—With catarrhal influenza ear complications often retard recovery. Otitis media, either suppurative or non-suppurative, sinus disturbances, mastoiditis, all postpone convalescence or are early complications, all of which offer good prognoses if promptly treated. In only occasional cases which have been under treatment during reasonable periods, has meningitis developed from aural infections. Serious hemorrhagic diathesis with influenza, types of complicating purpura, have added depressing factors in occasional cases (Pick). In America we have seen but few of these. Other complications include disturbances of one or many organs in individual cases; many will be mentioned in connection with other forms of influenza in the following pages; the prognostic significance of all of these cannot be separately considered but will receive attention in connec- tion with the diseases of the separate organs. 2. Gastro-intestinal Influenza As a rule the gastro-intestinal form runs a short course, during which the patient is uncomfortable for from 2 to 5 days because of the vomiting, at times obstinate watery diarrhea, abdominal paim, tender peritoneum and rarely ulceration in either the small or large intestines. In most of these cases there is enlargement of the spleen. The latter is proportionate to the severity of the infection. The prognosis of gastro-intestinal grip is good, though full recovery (return to normal resistance) is slow. Heart and other complications are not infrequent, the lungs are but rarely involved. BACTERIAL DISEASES 129 3. Influenza of the Nervous System The nervous system may be either (a) primarily or (b) secondarily involved by the Pfeiffer infection without catarrhal symptoms. (a) Primary invasion of the nervous system, leads to a train of posi- tive symptoms, varying according to the severity of the disease. In children there may, even in favorable cases be convulsions, early evidences of meningitis, the presence of the infecting agent in the with- drawn lumbar fluid, or there may be active delirium during a limited period. Most of these cases terminate favorably. In the adult the pri- mary symptoms are less severe, as a rule, and the outlook from the be- ginning is favorable, in spite of great prostration, severe headache, annoy- ing myalgias; in the severer cases there is delirium and at times somno- lence; occasionally insomnia. Primary peripheral limited neuritis, leading to severe neuralgia is favorably influenced by treatment. (b) The complications due to organic change in the nervous system at the height of the disease or manifested early, are of serious na- ture. With alcoholics “wet brain/’ alcoholic meningitis with all of the symptoms of delirium tremens may lead to death in deep coma from the sixth to the tenth day. Acute encephalitis simulating cerebral apoplexy, with or without motor paralysis or aphasia, occasionally monoplegia—usually of an arm —may promptly cause death. Meningitis with mastoiditis, venous thrombosis, or secondary meningitis to catarrhal infection of the nasopharynx is serious unless the condition is promptly recognized and surgical relief is obtained. Secondary multiple neuritis offers a good prognosis; recovery is slow but restoration of function is likely to be complete. Abscess of the brain is not frequent; it has occasionally been found post mortem. My records offer no well authenticated case diagnosticated ante mortem save those secondary to otitis media and mastoid invasion. The prognosis in reported cases has been very bad. The statistics of our state hospitals for the care of the insane gathered after the panepidemic of 1889-90, prove the enormous influence of influ- enzal infection in causing psychoses. Our hospitals were filled with all varieties of psychoses usually developed during convalescence. In some there were long periods of depression (melancholia), in others exhilaration and hallucinations. Those not seriously burdened by heredity ultimately returned to full health. Neurasthenia in all of its forms may develop; it yields slowly after months of patient waiting or the fully developed habit may persist, to make the victim wretched during years or forever. 130 SPECIFIC INFECTIOUS DISEASES Myelitis and occasional ascending paralysis (Landry’s type) have been noted and are mentioned by Romberg and Osier. A study of the literature of these complications does not justify an encouraging forecast; no one man has a large material at his command, for the association of the myelitis of Landry's syndrome with influenza has been limited. 4. Influenzal Fever Occasional cases without the usual catarrhal symptoms present with marked features; there is irregular fever, at times it is continuous and the patient falls into a typhoid condition; the fever may be remittent, with or without chills; there are no lung complications as a rule. These febrile types may present a variety of pictures, but the prognosis in the uncomplicated cases is good, though there may be great prostration, at times cardiac anomalies and psychoses long after the disappearance of acute symptoms. Any of the complications associated with the other forms of influenza may develop in exceptional cases. The respiratory organs rarely suffer. References Eichhorst & Gerhardt. Berl. klin.

Pyogenic Infections—Septicemia—Pyemia (Sepsis, Blood Poisoning, Septicopyemia) Septicemia is a general disturbance due to the presence in the blood of septic, disease-producing bacteria or their products, i. e., toxins. Septice- mia may also be defined as a bacteremia or toxinemia (sapremia when products of decomposition are included). It is possible for sepsis to in- clude the presence in the blood of both bacteria (bacteremia) and toxins (toxinemia) at the same time. In contradistinction to pyemia (a surgi- cal affection), sepsis does not include suppurating metastatic foci. In all cases of sepsis, toxins finally become the cause of the general, i. e., con- stitutional symptoms, and are responsible for the consecutive degenerative changes in the vital organs of the body, i. e., heart, spleen, kidney, etc. Grave constitutional disturbances with degenerative changes may lead to death without evident bacteremia, as proved by blood cultural methods; these effects are always due to the overpowering toxinemia. Most constitutional infections are secondary to a primary local focue BACTERIAL DISEASES 131 through which, or from which bacteremia and toxinemia proceed (puer- peral sepsis, anthrax, pneumonia, gonorrhea, etc.). There are, on the other hand, grave forms of sepsis in which the constitutional disturbances are due to a prompt dissemination of disease-producing germs (streptococci usually) without known or evident local lesion from the blood stream to the vital organs, with the associated baneful and malignant results of toxic poisoning. These are the cases which offer the gravest forecast. There is always danger of septic deposits in organs which present changed or dis- eased surfaces to the blood and lymph stream. This is manifest in one of the gravest forms of septicemia—malignant endocarditis. In these cases, there is often grafted upon an old endocardial or valvular lesion an acute septic and malignant endocarditis from which, by the detaching of vegeta- tions to distant parts (emboli), grave complications (hemorrhagic infarcts) are added, which presage an absolutely unfavorable outcome. The septic type of endocarditis will be separately considered in connection with the diseases of the heart (See Septic Endocarditis). The search of the invading bacteria for a port of exit (elimination) leads to serious kidney change, i. e., septic nephritis in the graver forms of blood-poisoning, with the characteristic urinary evidences, which is never to be lightly regarded. Marked reduction in the quantity of the urine se- creted, lowered urea output, albuminuria, large numbers of casts with evi- dences of invasion of the nervous system, are among the symptoms which call for a guarded, usually a bad prognosis. The staphylococcus infections offer a more favorable prognosis than do the streptococcus. The latter infections, though grave do not always lead to death. (The staphylococcus does not enter the blood-stream so easily or readily as does the streptococcus, but when it does it has recently been held by pathologists that it is much more serious. This question is still sub judice.) The streptococcus is less likely to cause pyogenic processes (abscesses) than the staphylococcus. It enters the blood stream quicker and with greater ease than does the staphylococcus. Once the staphylococcus has caused bacteremia, it is a question whether it does not offer a less favorable prognosis than does streptococcemia. Many forms of septic and pyemic infections are likely to he mixed, complicating many other primary infections to which reference has been made in other chapters; these include, diphtheria, pneumonia, tuberculosis, typhoid fever, etc. Such mixed infection, as has been repeatedly demon- strated, adds a large element of danger. Organic diseases of the vital organs invite infections which are largely responsible for the death of the individual. These are considered “ter- minal infectionsOsier quotes Flexner, who analyzed 255 cases of chronic renal and cardiac disease in which full bacteriologic examinations were made at the autopsies “in which 213 gave positive, and 42 negative results.” 132 SPECIFIC INFECTIOUS DISEASES The infections were local and general; the former were common “in a large proportion of all cases of Bright’s disease, arteriosclerosis, heart disease, cirrhosis of the liver, and other chronic disorders.” In these cases it was found that acute pleurisy, pericarditis, peritonitis, meningitis or endo- carditis were the usual seats of local infection. The most serious infection associated with previously existing organic disease is the streptococcus. General gonococcus infection, when associated with gonococcus endo- carditis—and it is very often—has in my experience been uniformly fatal. Flexner contends that “the blood serum of persons suffering from ad- vanced chronic disease was found by him to be less destructive to the sta- phylococcus aureus than normal human serum.” Lenhartz’s statistics show that 75 per cent of all general sepsis is dependent upon streptococcus infec- tion. Staphylococcus and pneumococcus infections are responsible for 8 to 9 per cent. The female generative tract is the most frequent source of general infection, due to unclean hands, instruments, clothing, usually to prevent- able factors for which the physician is not always responsible. Surgical operations with consecutive infections are also a fruitful source of septic poisonings. Phlebitis with or without septic thrombosis must always be considered a menace, and when due to streptococcus infection is a serious complication. Septic thrombosis, with single or multiple thrombi, is a serious complica- tion with any form of sepsis; the prognosis is grave, depending largely on the depth of the toxinemia, the pathologic changes in vital organs (heart and kidney mainly) and the location of the thrombus. Apparently innocent local infections without grave initial symptoms may lead to grave constitutional disturbances due to bacteremia and toxi- nemia, or to changes in vital organs, with pus-producing organisms (pyemia), to multiple abscesses in the various organs of the body. Thus simple follicular (streptococcus) tonsillitis offers innumerable examples of the truth of this possibility. Other examples are otitis media, bone invasion, suppurating hemorrhoids, superficial or deep skin infections, prostatitis, urethral abscess, gonorrhea and trivial injuries. The prog- nosis is always clouded when there are multiple abscesses associated with pyemia in the lung or liver, or in both at the same time. The height and behavior of the temperature serves as a valuable guide in connection with the pulse for prognosis. With pyemia, multiple abscesses, purulent phlebitis and thrombosis, the character of the fever is likely to be intermittent, and profuse sweats fol- low with a fall of temperature. Severe chills in these cases are the rule. When with pus-producing infections there are long periods of apyrexia between the chills, the prognosis is more favorable than in cases with con- tinuous elevation of temperature—barring, however, those cases of malig- BACTERIAL DISEASES 133 nant endocarditis of the intermittent type, which always offer a grave fore- cast. Chronic cases due to the streptococcus viridwns may remain afebrile during several days, or the temperature may be but slightly elevated with or without the chronic form of endocarditis, for which this strain is re- sponsible ; the prognosis remains bad and the attendant is not to be deluded by the apparent improvement. Cases in which the temperature gradually falls to normal or below, with improvement of pulse and other constitutional symptoms offer a good prognosis, but in these, it requires more than a few days of the afebrile state before a positive opinion as to the outcome is justified. The effect of the toxinemia on the vasomotor system through the spinal centers is of paramount importance. If the heart, though rapid, shows no evidences of insufficiency, its separate sounds remain clear and fairly strong, and endocarditis does not develop, there is at least a powerful staff upon which we may continue to lean. Dilatation of the heart with relative mitral insufficiency, with or with- out accentuation of the second pulmonic sound and rapid pulse, persistence of fever, nephritis, and evidences of cerebral invasion, offer a bad prognosis. Patients developing sepsis from whatever source, with pre-existing endocarditis are handicapped, and in these the prognosis is always doubtful. The influence of hemorrhagic infarcts is always bad; to these we again refer in the chapter on Malignant Endocarditis. The blood shows marked leukocytosis in most cases of sepsis with reduc- tion in the number of red blood corpuscles. There are cases of fully devel- oped sepsis in which the blood picture is not materially changed. Limbeck has reported cases of puerperal sepsis without leukocytosis. The blood offers no data so far as the count or appearance of its corpuscular elemeids are concerned which influence prognosis. The degree of bacteremia in occasional cases does influence prognosis -—favorable in accordance with the number of bacteria in the blood stream. Pneumonia as a complication of sepsis or pyemia is always serious. Frequent respirations are not always due to pneumonic consolidation, hut. to a number of factors including heart weakness, muscular enfeeblement, hemorrhagic infarct, etc. The spleen is always more or less enlarged with all forms of blood- poisoning. It offers no prognostic data. The grave forms of sepsis are complicated with cerebral and meningeal symptoms. Septic meningitis is usually a fatal complication; with erysipelatous inflammation, it always proves serious (See Erysipelas). Duration.—The duration of all forms of blood-poisoning depends upon the source and extent of the primary lesion, the life history of the infecting germ, and many other factors. Acute sepsis may kill in a few days. 134 SPECIFIC INFECTIOUS DISEASES Atypical cases, particularly streptococcus viridans infection with endocar- ditis, runs a chronic course covering many months. We recently saw a case which died at the end of the fourteenth month, of cerebral infarct. The average duration of septic processes may be safely placed between 5 to 8 weeks. Pyemia is often chronic. Sudden death in acute or chronic cases may be due to thrombosis or embolism, cardiac insufficiency, pneu- monia or a variety of complications considered in connection with the spe- cial diseases. Pneumococceinia is separately considered. References Lenhartz. Die septischen Erkrankungen. In: Nothnagel’s Handbuch, etc. 1903, Bd. Hi. Limbeck. Klin. Pathol, des Blvtes. 1896. Osier.

Diphtheria General Considerations Bacteriology.—Diphtheria is an acute infectious disease, due to the Klebs-Loeffler Bacillus (1883-1884) (a short rod-shaped microorganism, which may be curved or club-shaped at one end. Gram-positive, it shows polar granules when stained with methylene-blue, with characteristic ar- rangement in groups like Chinese figures) contagious, attacking by predi- lection the tonsils, uvula, soft palate, postnasal space and larynx, extending into the trachea and bronchi and invading the lung in the graver infections, with evidences of general toxemia. The disease is sporadic and epi- demic. Uncontrolled, the infection is always serious and associated will a high death rate, hut is favorably influenced by the Behring a?ititoxin (1892) in almost all cases, if treated on the first day. History.—The disease is now prevalent in all parts of the civilized world, attacks the young especially, rarely the aged, though it is not infre- quent in adults during middle life. In 70,000 cases collected (London Lancet, 1878) the cases were distributed as follows, according to ages: Under 12 months 9 per cent 1 to 5 years 45 5 to 10 “ 26 “ “ 10 to 15 “ 9 “ “ 15 to 25 “ 5 “ “ 25 to 45 “ 3.5 “ “ 45 years and over 2.5 “ “ Jacobi’s case is tbe youngest on record and was 9 days old. The sta- tistics of the New York Health Department (1891-1900) show that 80.8 BACTERIAL DISEASES 135 per cent of deaths occurred under 5, and 17 per cent between 5 and 10 years. The disease was known before the Christian Era (angina maligna, angina gangrsenosa) ; in Spain, where there were epidemics at short inter- vals between 1553 and 1618; in Italy, from 1610 to 1650; in France as early as 1736; 1744 in England; 1752 in Germany, and the same year it appeared in America. Bretonneau’s description of the disease remains among the classics of medicine, as well as that of Trousseau (1821-1828). There can be no doubt of the fact which clinical experience and a study of medical litera- ture prove, that the character of the disease, its virulence and mortality, are influenced by unknown factors, and vary materially with fresh epi- demics and during different years. The various seasons of the year do not influence the mortality of diphtheria, though the disease is more frequent during the winter months. In Germany the mortality reached its climax in 1886 with 122,000 deaths. In 1900 there were 45,000 deaths. In 1885 the number of deaths due to the disease in Germany was 122.7 per 100,000; in 1895, 54; and in 1905 only 22.4. Huttall and Smith offer the following figures, showing the maximum and minimum death rate due to diphtheria in 100,000 of inhabitants in Boston, Providence, Hew York and St. Louis: Maximum. Minimum. Period of Observation. Boston 163 in 1881 51 in 1891 1861-1895 Providence 314 in 1877 8 in 1868 1868-1895 New York 208 in 1877 23 in 1873 1868-1893 St. Louis 314 in 1877 8 in 1868 1868-1895 Factors Influencing Growth of Disease.—The body, including the blood and mucous membrane particularly, offers marked resistance to the disease. There are factors, as Trumpf has demonstrated, which are necessary for the development of the disease. They are: 1. A high degree of virulence of the infecting agent. 2. The deposit of large numbers of bacilli on the mucous membrane. 3. The membrane must be in a suitable condition to offer a habitat for the proliferation of the bacillus. 4. The infected individual must be susceptible; hence this factor and the others are variable, protect or expose the same subject to the disease at different times. Mixed infection with pneumococci, staphylo- and streptococci, influen- ces the prognosis of diphtheria materially. 136 SPECIFIC INFECTIOUS DISEASES A degree of immunity is developed by a single diphtheria infection. Diphtheria infection added to already existing scarlet fever is not asso- ciated with the same danger as is the addition of scarlet fever to diphtheria (Uppenheimer). Zucker’s statistics show second attacks in only 0.9 per cent, and third attacks in 0.13 per cent of cases. Carriers.—Malignant as well as benign diphtheria may be conveyed by “carriers” who may or may not have had the disease. The mildest type of the disease in one individual may transmit the most malignant form to others. Pharyngeal Diphtheria The following is the classification of pharyngeal diphtheria, nnder which the subject will be treated: 1. Mild infection of the fauces, tonsils, without severe general toxemia. 2. Pharygeal infection with severe general toxemia. (a) ISTon-gangrenous (b) Gangrenous . I. Mild Infection Without Several General Toxemia.—With mild in- fection of the tonsils and surrounding tissues, there are generally no evi- dences of severe constitutional toxemia, and if the case is recognized on the first or during the second day of the disease and promptly injected with a sufficient number of antitoxin units, improvement is prompt as a rule, the membrane begins to disappear, fever and pulse improve, glandular enlarge- ments recede, and between the sixth and tenth day convalescence has com- menced and in the majority of cases is uninterrupted. Cases which begin with laryngeal invasion so limited as to cause but few symptoms, with croupy cough, but without other evidences of laryngeal stenosis, may later “ascend” with invasion of tonsils and but few constitutional symptoms, when the prognosis is less favorable than in the first mentioned cases— because time has been lost before active treatment was commenced. If laryngeal diphtheria in these cases does progress in spite of the fail- ure to make an accurate bacteriological diagnosis early, the prompt treat- ment of the disease after the appearance of pharyngeal diphtheria will lead to recovery in over 85 per cent of such cases. If from these apparently mild cases there is progression to the posterior nares, and greater invasion of the cervical glands there will, as the process advances, be evidences of increasing toxemia. Fever may not be high, but the heart and kidney may suffer most, and the prognosis is accordingly influenced unfavorably. Leukocytosis is present in all of .these cases. Its influence on prognosis will also be studied in connection with the administration of antitoxin—to which reference will be made later in this chapter. The prognostic value of leukocytosis, has been epitomized by Kautback and Andrews as follows: BACTERIAL DISEASES 137 “1. A high leukocytosis signifies a good reaction and is present in those cases which recover. “2. A low leukocytosis at the height of the disease, before antitoxin has been injected, accompanies most, if not all fatal cases. “3. The high leukocytosis of well reacting cases after and during antitoxin treatment steadily diminishes, the number of cells decreasing by 50 per cent in 3 or 4 days.” Cases which begin in the nose with descending disease, i. e., final de- position on tonsils and soft palate, even without constitutional symptoms at first, are usually complicated with painful enlargement of the lymphatics, increasing anemia, and before the fifth or sixth day there are in many cases evidences of toxemia, albuminuria, normal or subnormal or slightly ele- vated temperature, and with increasing heart weakness the patient’s con- dition becomes grave. These complications with beginning nasal diph- theria are as a rule prevented if the disease is promptly recognized, and the patient injected. Albuminuria without other symptoms or microscopic elements denoting nephritis, is present at sometime in the majority of these eases, and does not cloud the prognosis. II. Pharyngeal Infection with Severe Toxemia. (a) Hon-gangrenous Pharyngeal Diphtheria with Severe Tox- emia.—The majority of pharyngeal infections which are associated with severe toxemia are found among the poorer classes, in tenements and homes where there are many children, where the physician is rarely called early and the process with its overpowering toxemia is far advanced before treat- ment is instituted. In these cases, as a rule, there is some nasal invasion also; the general appearance of the patient is unfavorable, color pale, face puffy, at times ashen; breathing rapid; pulse accelerated, small and with- out character; urine is reduced in quantity and albuminous, with hyaline and granular casts; temperature behaves irregularly, at times is high, in some cases subnormal or only slightly elevated, the odor foul. In these non-gangrenous cases, there is less sloughing of tissues, but the membrane presents a greyish brown or dirty yellow appearance; the discharge from the nares is at times watery, almost continuous, ichorous, causes ulceration of the skin; and in spite of large doses of antitoxin there is a large mor- tality, ranging between 15 and 50 per cent, depending upon the day of injection, the extent and character of the associated lesions and the depth of toxemia. Albuminuria with casts, when an expression of acute non-sup- purative nephropathy (Councilman pathology), or glomerular or tubular invasion, adds an element of danger. (b) Gangrenous Pharyngeal Diphtheria.—The gangrenous form is always serious. These cases may arise sporadically or during epidemics; they show the character of the infection. Trousseau in 1846 called atten- tion to these cases. They have become less frequent during the past 20 years. In gangrenous diphtheria we have the picture of deep sepsis with 138 SPECIFIC INFECTIOUS DISEASES all of its classic constitutional symptoms to make the prognosis exceedingly grave. There are in the worst cases dark brown, blackish, foul-odored sloughs, with other local manifestations and swelling of glands; foul dry brown tongue; cracked ulcerated lips, almost continuous dark or bloody nasal discharge; increasing weakness; great thirst; thready pulse; albu- minuria, usually some form of nephritis. In occasional cases death fol- lows a number of hours of urinary suppression after coma or disturbed sen- sorium, including delirium and great unrest. In these cases there is likely to be hypoleukocytosis which is unaffected by serum injection. Acetonuria and acetonemia with glycosuria may be present in the gravest cases. Gangrenous cases developing laryngeal stenosis offer most unfavorable prognoses. Hoarseness, gradually increasing with this and most forms of diph- theria, is an ominous symptom and usually leads to stenosis, if the patient lives long enough. Cyanosis, rapid pulse, delirium, noisy respiration showing extreme stenosis, with air hunger—a pitiful picture of suffering —usually end the scene (carbonic acid poisoning). Nasal Diphtheria and Laryngeal Diphtheria Nasal and laryngeal invasion (stenosis), as has been emphasized in connection with all forms of the disease, are always of serious significance whether primary or secondary. Skin Diphtheria There are in some cases diphtheritic ulcerations of the shin. The inva- sion of the skin alone is rarely met without pharyngeal deposit. Its prog- nosis is relatively favorable when primary, depending on the degree of virulence and the time of injection. Conjunctival Diphtheria Conjunctival diphtheria is not often seen in hospital or private prac- tice. Occasionally during epidemics a case arises, in which with naso- pharyngeal disease the conjunctiva is infected. Unless improvement is prompt and the case has received early treatment, the danger to the eye is great and destructive ulceration may result. Diphtheria of the Vulva My experience includes 4 cases of vulvar diphtheria, all seen during the 'puerperal period. All had been treated for puerperal sepsis; in 3 for- tunately the antitoxin and local treatment saved the patients. 1 case seen during the preantitoxin period died with all the symptoms of puerperal peritonitis. BACTERIAL DISEASES 139 The amount of glandular invasion is as a rule proportionate to the extent of the nasopharyngeal involvement, and is an expression of the malignancy of the process in most, but not in all cases. There is but slight swelling of the glands in occasional cases of great virulence; on the other hand I have seen a goodly number of cases in which benign diphtheria was associated with glandular enlargement out of all proportion to the deposit, or to the extent of the disease. Complications of Diphtheria Nephritis complicates 50 per cent of all diphtherias. Councilman considers this a true non-suppurative interstitial nephropathy; in some cases there is hemorrhagic nephritis, at times atypical forms resembling parenchymatous disease of the kidney. The albumin loss is moderate, less than with scarlatinal nephritis; there is also less dropsy—often none. Albuminuria may in the milder cases prove to be transitory; the amount of albumin otfers no prognostic data. In the severe and malignant types, nephritis may show but slight albuminuria in the presence of the gravest possible conditions. It may be concluded that cases which are albumin-free offer a better prognosis than do those in which it is present, from whatever cause. If albuminuria is transitory, the prognosis is as a rule good in the absence of heart weakness or other depressing conditions. With nephritis and scanty urine, abundant casts, (hyalin, granular and blood) the prognosis is unfavorable. Uremia may end life within a limited period. This is not frequent. Diphtheritic nephritis does not cause dropsy. When the latter is pres- ent, it is due to circulatory embarrassment and is a serious complication. Chronic nephritis may develop after the acute symptoms have dis- appeared. This may be overlooked unless the cases are followed. The prognosis will be further considered in the chapter on nephritis. Heart Complications.—The heart is subject to myocardial change in all cases of diphtheria, the extent depending entirely upon the malignancy of the toxemia; its muscle may undergo either interstitial change (myocardi- tis interstitialis), fatty, or parenchymatous degeneration. The interstitial type of myocarditis is the most frequent cause of heart weakness in diphtheria (Jores, Romberg and others). The prognosis as influenced by the heart, depends on the extent of the degeneration or myo- carditis. In the milder cases this is limited, in the gangrenous toxemias it is far-reaching. With dilatation, weak heart sounds, rapid small pulse, with or without murmurs, the prognosis is bad. Irregularity of the pulse during the acute and toxic period of the disease is always serious; later however, during convalescence with or with- out paralyses, it is less serious, and great rapidity of heart action and 140 SPECIFIC INFECTIOUS DISEASES erratic hearts are often well borne during long periods, leading ultimately to recovery. Endocarditis and Pericarditis if present are due to secondary infec- tion. They are likely to prove malignant and offer a grave prognosis (ma- lignant diphtheritic streptococcus endocarditis). Sudden Death.—There is in the profession a fixed belief that diph- theria often leads to sudden death. This is not based upon clinical obser- vation, and is unjustified by experience. Patients rarely die suddenly during the period of convalescence or at the height of the disease. I am in full accord with Harris, who says: “there have always been timely warnings of danger.” Experience proves that the heart weakness or other cardiac anomalies offer positive symptoms and physical signs, during a period of sufficient length to make their pres- ence recognized. Careful examination of the heart, repeated daily during convalescence, will give sufficient warning of a failing degenerated heart muscle; the same is true of all periods of the disease. It will be necessary in adding to other prognostic signs, the data offered by the heart, to consider as Harris has suggested: 1. The heart sounds 2. The position of the cardiac impulse 3. The pulse 4. The outline of cardiac dullness. Irregularity with reduplication of the second sound and gal- loping rhythm are always serious. Relative mitral insufficiency may persist for an indefinite period; in the absence of other grave symptoms, without extreme dilatation, these patients recover and the murmur ultimately disappears. Tachycardia due to paralysis of the pneumogastric, is often well borne by most children during long periods. To this I will again refer when considering diphtheritic paralysis. Embolic Infarcts are rare; if present they are an expression as a rule of malignant endocarditis or septic processes, and are therefore serious com- plications. Purpura, petechise, hemorrhages from mucous membranes are asso- ciated with heart weakness in malignant cases and are of grave import. Diphtheritic Paralysis.—Paralysis is a complication or sequel of diph- theria in about 12 per cent of all cases, and is by no means an expression of the severity of the diphtheritic infection. I have seen a number of cases which were so mild that no physician had been called, which were treated by mothers for mumps, in which paralysis developed. Often the gravest infections are entirely without this complication. Paralysis as a rule is a sequel of the disease, developing from 3 to 10 weeks after infection. BACTERIAL DISEASES 141 In severe cases glossopharyngeal paralysis becomes a serious com- plication as early as the fifth to the eighth day. In these, the chances for the patient are unfavorable. Simple uncomplicated paralysis of tiie soft palate when it fol- lows the acute stage, offers a favorable prognosis; recovery may be ex- pected in from 3 to 10 weeks. Paralysis which interferes with deglutition, (glossopharyngeal) with choking cough, is always more serious than paralysis of the soft palate alone. It may lead to “Schluck pneumonia” or sudden asphyxia. Paraly- sis associated with changes in the voice, an unsatisfactory and inefficient cough, without a normally closing glottis, is always to be feared because of the danger of pneumonia from the entrance of food etc. into the air passages. Many of these cases,, under close watching and feeding, recover slowly. Paralysis of the extremities, usually most developed in the legs, if not associated with severe glossopharyngeal or pneumogastric paralysis, tends to full but slow recovery, requiring from 5 to 10 months. I have never in my own practice seen a case of hemiplegia with diph- theria. A number have been reported; probably these were embolic, thrombotic, or due to cerebral hemorrhage. The prognosis must of neces- sity be grave, but recovery is not impossible. Polleston, in 9,075 cases of diphtheria included 6 of hemiplegia, of which 4 died. In 1 of these there was an embolus in the cerebral vessels. When the respiratory muscles are involved (pneumogastric paralysis), the prognosis will be grave in proportion to the extent of the respiratory embarrassment. In these cases there is, as a rule, associated tachycardia. While the complica- tion will always cause the attendant great anxiety, and is serious, let him remember that in extreme cases recovery may follow. Long continued pneumogastric paralysis with fully developed symptoms have in my experi- ence finally yielded, and full restoration to health has followed with nor- mal pulse and respiration, in a number of cases. ]STo positive prognosis can be given; the patient until fully restored stands on the edge of a precipice, and may fall at any moment. Ocular paralyses may be the only evidence of diphtheritic palsy, or these may be a part of multiple neuritis and far-reaching paralysis. The prognosis is as a rule favorable when limited to the eye muscles. Nasal diphtheria is likely to be followed by paralysis of the lower extremities, at times by quadriplegia. The prognosis, if this is a late complication, is good. Fully developed paraly- sis which develops at the height of infection offers a very had prognosis. TIave the number of diphtheritic paralyses been increased by the use of the von Behring antitoxin? This question can be ansivered without qualification in the negative. There are a larger number of diphtheritic paralyses, it is true, but not because of antitoxin. There are fortunately a larger number saved, hence the increase of paralyses; our observation 142 SPECIFIC INFECTIOUS DISEASES of cases is closer, a larger number are recorded by health authorities than formerly. Neither the close study of this subject by Rolleston, nor the statistics of Fibigan prove that the Behring serum has “altered the incidence to any appreciable extent.” Persistent vomiting during the acute period of infection is either due to diphtheria of the stomach, nephritis, cardiac insufficiency or other seri- ous conditions; if unrelieved, there is cardiac incompetence, and death follows. Pneumonia.—Pneumonia (lobular) is found in at least 50 per cent of autopsied diphtherias. When developed early it is among the complica- tions least amenable to treatment, and death is likely to follow. The unfavorable symptoms are increasing dyspnea, cyanosis, rapid small er- ratic and irregular pulse, physical signs of collapsed lung, and inability to cough, with hurried respiration and evidences of toxic nephritis. Pleurisy—serous and purulent—are not frequent; when late, less seri- ous than early. Otitis media suppurativa may be an early or late complication. Recov- ery follows unless it is present during the height of malignant infection, when it is simply one of many conditions which cloud the prognosis. Liver and spleen offer nothing of importance for our purposes. Parotitis is not frequent, but if present is likely to be an expression of profound toxemia and always secondary. Relapse Relapse occurs occasionally. In some cases the habit of reproducing membranous deposit is formed and is encouraged by the use of local treat- ment ; such cases if left untreated, promptly recover as a rule. Relapse immediately after acute infection or as the membrane is cast off, aggravates all symptoms, retards recovery, but offers a good prognosis if the patient is not exhausted and the disease is non-malignant. Associated complications (nephritis, myocarditis, etc.) naturally modify the prog- nosis. Diphtheria and Antitoxin Blood Counts after the Injection of Antitoxin.—Prognostic data may be furnished by blood-counts before and after the use of the serum. Hypoleukocytosis follows the injection of the serum; if after 3 or 4 hours the leukocytic count present before injection is not reached, the prognosis is unfavorable. A return to a higher leukocytic count after injection than was primarily present is favorable. In unfavorable cases the hypoleukocytosis continues after injection; there is no effort to in- crease phagocytosis (Simon). Serum Sickness.—Methods have been and are being devised which have BACTERIAL DISEASES 143 reduced serum sickness materially. The use of calcium chlorid has been efficacious (Netter-Consin-Gervin). Serum sickness is present where horse serum was used: In cases where 1,500 units were injected in 8.6 per cent In cases where 1,500 to 4,500 units were injected in 13.13 per cent In cases where 4,500 units and upward were injected in 18.91 per cent. While painful arthritides and eruptions have followed the use of the serum in my practice, I have never recorded a death traceable to it. The use of lamb serum (Ascoli) offers encouragement, for by it, serum sickness becomes an infrequent complication. It will however prove more difficult to obtain a sufficient supply of this than horse serum. Behring’s newer methods will reduce this complication, it is hoped. It requires no extensive argument in considering the prognosis of diph- theria to prove to the clinician as well as to the lay world the fact that the addition by von Behring (1892) of his antitoxin to our armamentarium at once added a remedy which promptly changed the prognosis of the dis- ease. Within 3 years after its introduction, von Behring proved that in Ber- lin at the Charite in cases where antitoxin was used the mortality was reduced to 8 per cent against 32.1 per cent in the Berlin Bethany Hospital, where it had not yet been introduced. These and the figures which are to follow, with the experiences easily obtained from those who practiced dur- ing the pre-antitoxin period and have been privileged to continue their ob- servations since, are sufficiently convincing. We now enter the treatment of the disease with reasonable certainty of success, formerly it was with fear and a painful appreciation of the limitations of our art to combat the monster. Baginski has demonstrated a mortality of 15.8 in 10,000 inhabitants before the use of antitoxin; since its use a reduction to 2.4 in 10,000 in 1908, and as low as 3. in 10,000 in 1907—the year of a severe epidemic in Germany.

Antitoxin influences local diphtheritic deposits favorably, the ear- lier it is used. 3. If used early there are no advances of the disease to the larynx. 4. The energetic and early use of antitoxin will save many lives in the presence of laryngeal stenosis, unless the cases are malignant. - 5. The use of antitoxin adds materially to the chances of intubated and tracheotomized children and adults. 6. Antitoxin cures the croup of measles. BACTEKIAL DISEASES 145 References Ascoli.

Pneumococcus Infection Lobar Pneumonia (.Pleuropneumonia, Lung Fever, Croupous Pneumonia, Fibrinous Pneumonia, Lungenentziindung) The most frequent expression of the systemic infection due to the pneumococcus is lung fever—lobar pneumonia. It is a general infec- tion usually associated with febrile disturbances, in which large portions of one or both lungs are involved in a croupous inflammation, due as a rule to the pneumococcus of Sternberg and Fraenkel, though croupous pneu- monia may be the local expression of other general bacterial contamina- tion. Bacteremia, toxemia, pulmonary consolidation with consecutive obstruction and cardiac asthenia, form the complex which demands atten- tion and influences the prognosis of the disease. The prognosis is mate- rially influenced by the occurrences of double or multiple infections, and the further fact that the bacteriology of many of the acute infections which often complicate pneumonia is unknown or uncertain (Pye-Smith). As soon as it was fully understood that pneumonia is only the local ex- pression of a general disease, a step forward was taken which has had a powerful influence on prognosis, more particularly the prophylaxis of the disease. Sir Herman Weber in England (1869), Juergensen in Germany 146 SPECIFIC INFECTIOUS DISEASES (1876), and Austin Flint, Sr. (1877), in the United States, were pio- neers in establishing our modern conception of pneumonia. Pneumococcemia With modern bacteriologic methods the presence of pneumococcemia is established in over 70 per cent of all cases of croupous pneumonia. The other and leading local manifestations of general pneumococcus infection are tonsillitis, otitis media suppurativa, meningitis, cholecystitis, endocar- ditis and arthritis. Among the most valuable data showing the influence of pneumococ- cemia on the prognosis of croupous pneumonia are those furnished by Dochez, from which we quote. The bacteriologic studies of the blood were made in 37 cases of lobar pneumonia. “The pneumococcus v7as isolated from the blood in approximately 50 per cent of the cases studied. The course of the infection in individuals with pneumococcus in the blood was more severe than in those in which no organism could be cultivated from the blood; 77 per cent of the patients with positive blood-cultures died, and 79 per cent of the patients with negative blood-cultures recov- ered. In fatal instances of pneumonia, where the pneumococcus was found in the blood, the number of organisms per cubic centimeter of blood was very high in the last stage of the disease. In individuals dying of pneumonia without evident blood infection, the disease w?as charac- terized by a rapid spread of the local process in the lungs!” It is believed by Dochez as the result of his observations, that the “symptoms of col- lapse developing on the fifth or sixth day of lobar pneumonia, are often the expression of serious invasion of the blood by the pneumococcus.” The virulence of the strain in the individual case as shown by animal experimentation and clinical experience has a direct influence on the prognosis of the disease. Rosenberger and Dorworth found that 54 per cent of their patients in whom blood-cultures showed organisms died; and 50 per cent of the patients who died showed no blood contamination. Melt- zer and Lamar found that by intrabronchial insufflation of cultures of a very virulent pneumococcus, typical pneumonia lesions were invariably pro- duced. These experiments gave a mortality of 16 per cent and bacteremia was present only in fatal cases. Wallstein and Meltzer experimented with non-vimdent pneumococcus; they obtained typical consolidation of the lungs, with no mortality and no bacteremia. These views according to Meltzer, justify the conclusion which is by no means new, that the anatomic changes in pneumonia are not the immediate cause of death, and they do not present the essential features of the disease; “on the contrary they are manifestations of the body’s fight against the disease.” We would add that improvement and the favorable termination after crisis occur without material change in the structures involved in pneumonia; BACTERIAL DISEASES 147 the heart is relieved of its burden in spite of the practically unchanged area of consolidation through which it must, for a few days at least, con- tinue to force the blood. There is very likely in some way, at the time of crisis, a change in the character of the toxins of the pneumococcus.' Cole says, that there is “a neutralization of the intoxication rather than a destruction of the bacteria existing within the body.” Lees’ epigram- matic remark is applicable in the consideration of our subject. “Let it he remembered that every case of pneumonia is a fight for life” to which we add, no case is so severe that it may not recover; none so mild that it! may not become serious. In considering the prognosis of pneumonia the factors which concern us most are: 1. The malignancy of the infecting organism. 2. The effect of the toxemia and the associated local lung lesion on the cardiovascular system. 3. The resistance offered by the patient. 4. The extent of the pulmonary and associated lesions. 1. The Malignancy of the Infecting Organism.—The malignancy of the infecting organism requires no further consideration. The foregoing paragraphs have proved that the prognosis depends very largely upon the virulence of the infecting strain, the result of the bacteremia and the toxemia. 2. The Effect of the Toxemia and the Associated Local Lung Lesion on the Cardiovascular System.—This is the paramount issue in the prog- nosis of pneumococcus infection. We are not dealing with the heart alone; we must consider the vasomotors, and the effect of the toxemia on both. Passler and Romberg reported a series of experiments which served to prove the relative importance in the production of the so-called heart weakness of pneumonia, of the heart itself, and of the vasomotor system. Experiments made with the pneumococcus and the Bacillus pyocyaneus, in which rabbits were inoculated, proved conclusively that the vasomotors were weakened and showed evidences of paralysis. The prognosis of pneumonia depends largely upon the baneful influ- ences which the toxins exert upon the vasomotor centers in the cord. Primarily the toxemia leads to cardiac asthenia and vasomotor paral- ysis, to which must be added the changes in the right half of the heart, the far-reaching degenerative changes in the myocardium, the heart clots, and the mechanical obstruction in the pulmonary circuit. The effect of pneumococcus toxemia on heart and vessels is malignant; but fortunately for the prognosis, it is short lived. The heart and vaso- motors therefore are to be cautiously observed for prognostic data. Blood-pressure Study.—Associated with the influence on the heart and peripheral vessels we find in blood-pressure study a prognostic index of 148 SPECIFIC INFECTIOUS DISEASES great value. For reliable conclusions it is necessary to have full daily records, including frequent measurements, which positively lead to the early recognition of circulatory embarrassment. A systolic blood-pressure much below normal in pneumonia is unfavor- able; any great fall is ominous. “When the arterial pressure expressed in millimeters of mercury does not fall below the pulse rate expressed in beats per minute, the fact may be taken as an excellent augury; while the converse is equally true” (Gibson’s rule). It does not appear to us that the conclusions of Newburgh and Minot are to be accepted as proving that there is no failure of the vasomotor cen- ters in pneumonia. Low blood pressure may not “invariably” be “of evil omen” but clinical experiences prove that with falling blood pressure, loivering pulse amplitude and increasing pulse rate, the prognosis in all pneumonics is unfavorably influenced. To reach safe conclusions on this subject the pulse pressure data cover- ing many cases and a series of years are needed, and these we have secured before framing our conclusions. Data from a small material do not justify conclusions. Cases of pneumonia complicated by arteriosclerosis and chronic nephri- tis in which the blood-pressure remains abnormally high during a day or two, prove exceptions to the Gibson rule, and offer an unfavorable prog- nosis in most cases. The heart tires because of the added burden to force the blood through the consolidated lung and the obstructed arterioles. An abnormally high blood-pressure with a slow, tense thick pulse early, is always of serious significance. When considering the prognostic significance of some of the separate symptoms we will again refer to the pulse and heart. 3. The Resistance Offered by the Patient.—“The real predisposing moment in the case of pneumonia is to be found, not in those incidental and temporary impairments of resisting power which may occur in con- nection with mining work (speaking of the Rand) but in that abiding defect of resisting power which is normal to the native” (Sir Almroth Wright). The ability of children to resist all forms of pneumonia is surprising; the prognosis during early life is usually good. The mortality of pneu- monia during the first year of life is high, from the second year to puberty it is comparatively low, from thirty-five to forty it is high, from sixty to seventy, three-fourths of all pneumonics die. In old age, on the other hand, the disease is in many hospitals and during many seasons the principal cause of death. In old age the organs become more independent of one another than during early life; “they suffer separately, and the various lesions to which they may become subjected are scarcely echoed by the economy as a whole.” In old age latency of the disease is fre- quent and death may be sudden and unexpected in those who were about, BACTERIAL DISEASES 149 as if nothing were wrong with them. In the old as well as in the young, the association of diseases of the heart, lungs, kidney or other separate systems, which handicap the functions of organs in any way, add enor- mously to the danger of pneumococcus infection; this is particularly true of metabolic disturbances and arteriosclerosis (Eisner). The obese have a reduced resistance to pneumococcus infection, and melt away rapidly with symptoms of cardiac asthenia and nervous manifestations. Usually coma is a terminal symptom. Diabetics when infected with the pneumococcus offer an exceedingly grave prognosis. The majority of these cases are atypical and present complications which add to the dangers. The negro is more subject to the infection than is the white man. The inhabitants of the tropics when in their own habitations or in other cli- mates show a decided tendency to lung inflammation and have a lowered resistance. The report to the Rand Native Labor Association recently published is intensely interesting in connection with the fatality of pneu- monia among the African native, and especially the tropical native. “It was discovered that the blood-serum of whites and tropical natives has no immediate power to destroy the germ of pneumonia and that the blood of the natives does not acquire this power through either natural infec- tion, i. e., an attack of the disease, or artificial infection, i. e., inoculation. Power to resist the growth of the pneumococci in the system is acquired, however, in some degree by inoculation.” The blood of the African na- tive, and especially the tropical native, differs from that of the European in being incapable of developing a so-called bactericidal power toward pneumonic germs, and is inferior to it in respect of its “immunizing re- sponse” or ability to produce antibodies which shall prevent the hostile germs from becoming established in the body.” Pneumonia has caused a large mortality among the African natives working on the Panama Canal; kills large numbers of laborers and sol- diers (Wright) in Rhodesia, the African colonies and the Egyptian Sudan. Pneumococcus infections represent from 3 to 1 per cent of the diseases of the civilized races. Those who live in the open air are less disposed to pneumonia than are those who live in poorly ventilated or close quarters, and they offer greater resistance when infected. The disease is more fre- quent among workers who are exposed to storm and wet; among these the number of victims claimed is large. The excessive use of alcohol is a factor of enormous weight in invit- ing pneumococcus infection, and powerfully influences the prognosis. In our hospital we have found pneumonia in alcoholics among the most fatal of all diseases; the average mortality has rarely been below 50 per cent against a mortality of 10.3 per cent among the non-alcoholic patients. Alcoholics are usually neglected; they enter the hospitals or call for treat- 150 SPECIFIC INFECTIOUS DISEASES ment when the disease is far advanced and are often nephritics or other- wise diseased. Traumatism invites pneumococcus infection. Contusions of the thorax or perforation of the wall are frequently followed by traumatic pneumonia. There are cases in which there seems to be a predisposition, in which pneumonia is repeatedly developed. It is surprising to note how well the disease is borne by these patients, often the type proves to be abortive, but not infrequently the patient succumbs to a second or third infection. This is particularly true of children, many of whom develop either catar- rhal or croupous pneumonia with every bronchial catarrh contracted or with the ordinary infections of early life. All experiences prove the greater frequency of the disease among men than among women. This is unquestionably due to the greater exposure of the former to the hardships of life and inclemencies of the weather. The disease shows a large mortality among the mentally defective; the higher the grade of these, the lower the death rate. Ziemssen many years ago called attention to the fact that the perma- nent inhabitants of any locality offer less resistance to pneumococcus in- fection than do strangers or new settlers. We have found from a study of our material that the prognosis is more unfavorable in endemic cases where several members of a family are stricken at the same time, than in homes where but one patient is in- fected. In the first mentioned there is apparently greater virulence of the infecting strain. It was formerly held that the robust were subject to the disease; this is not true, for we very often find pneumonia the terminal infection of many diseases, either infectious, of metabolic origin, associated with, cachexias or malignant. Pregnant women offer a strong resistance to pneumococcemia but when infected the prognosis is grave and abortion is likely to result. Immunity following pneumonia is short-lived. One pneumococcus in- fection in old and young alike does not cause immunity, but tends to lower the resistance against future infection and invites subsequent attacks. Unfavorable surroundings, dust, the inhalation of gases, poor ventilation, continuous dampness, faulty nutrition, lower resistance, invite the dis- ease, and the infected offer a more unfavorable prognosis than do those whose environment has been more favorable. There are seasonal influences which influence resistance and prognosis. The disease is most prevalent during the winter months, the first four months of the year particularly, and it is during these months that the prognosis is least favorable. IV. The Extent of the Pulmonary and Associated Lesions.—It may be safely concluded that in the majority of cases the extent of the lung consolidation influences the prognosis very materially; this is particularly BACTERIAL DISEASES 151 true of double pneumonia. On the other hand there are many cases in which the area of infiltrated lung tissue bears no relation to the gravity of the disease. There are malignant infections which offer the gravest prognosis, in which only a limited part of one lung is involved. It is never in any case safe to offer a prognosis from the extent of the consolidcv- tion alone. There are always other data, which, when considered, justify a forecast of the individual case. Associated lesions, particularly throm- bosis, endocarditis, pericarditis nephritis, and many others to all of which separate reference are made are powerful factors and influence our conclusions. Temperature Chill.—The graver infections are associated with the most severe in- itial chill. Two or more chills are unusual; if these recur at short in- tervals during the first day of symptoms a malignant infection may he suspected. Chills are absent as a rule in children, but convulsions are not infre- quent; they are not always an expression of the gravity of the pneumonia. Severe, often repeated chills in the adult, with rapid development of the local lesion, rapid pulse, increasing evidences of heart weakness, mut- tering or active delirium, unfavorable facies and early evidences of pul- monary edema, are included in a symptom complex of foudroyant cases, in which there is prompt paralysis of the vasomotor centers and death within 24 to 36 hours. These cases are not frequent. In 14 per cent of our cases in adults the initial chill was absent. This was commonly observed in alcoholics, or in the aged and in enfeebled subjects. In the aged, with- out chill, the disease was of the asthenic type, to which reference will again be made. The mortality in these cases is very high. In 70 per cent of our influenza-pneumonias there was a severe initial chill. When this occurred the disease was of much shorter duration than in those cases in which there was no chill. In some of the latter cases there were large areas of consolidation, at times remnants of recent pneu- monia, without marked subjective symptoms, but in which there were positive physical signs. Most of these patients recovered completely. In many we found mixed infection, usually pneumococcus and strepto- coccus. Fever.—Early high temperature in pneumonia without evidences of heart weakness is by no means unfavorable. Such cases are often of short duration and terminate by crisis on the fifth to the seventh day of the disease. The frank fever is an expression of a good reaction. It is more favorable to have a high temperature early than after the third to the sixth day, unless at that time, it is transitory and is followed by a de- cided fall and profuse sweat. Sudden rise of temperature after the fifth day, after lysis has com- 152 SPECIFIC INFECTIOUS DISEASES menced or after crisis which persists, is an indication of added complica- tion requiring close investigation. Under no conditions is the 'prognosis of pneumonia to he dependent upon the revelations of the thermometer. Such, reasoning must lead to frequent error. I have seen malignant cases in which the temperature has been continuously low (101° to 102°) with, marked asthenia and limited consolidation. Many of these cases ran atypical courses, were uninfluenced by treatment, the heart showing increasing weakness from day to day; some proved to be of the migratory type in which there were fresh exacerbations with marked adynamia, and most of these died in the course of 2 to 3 weeks (subacute types). In connection with the study of the temperature, we are never to divorce ourselves from the consideration of the pulse (i. e., the heart, etc.), the character and frequency of the respirations, the mental state of the patient, the character of the sputum, to which the experienced clinician will add the general impressions which he receives from his survey, in- cluding facies and much which no teacher can specify, but which neverthe- less becomes a factor of great value in reaching safe conclusions in many cases. In the majority of cases in which the temperature remains continuously high, uninfluenced by any treatment, there are other symptoms proving the malignancy of the infection; in some of these before the end of the third or fourth day there are meningeal symptoms with possible hyper- pyrexia which promptly increase, and death may follow in from 12 to 24 hours. Fall of temperature to normal or slightly above with increase of respi- ratory embarrassment, cyanosis, and feeble pulse, with lowering blood- pressure and thin pink watery and profuse sputum, large and small moist rales generally distributed, is fatal in over 90 per cent of cases. In many cases there is a decided rise of temperature shortly before the crisis and in occasional cases there may be one or two exacerbations of tem- perature following but it is always of short duration, and convalescence is not disturbed. Subnormal temperature continuing after crisis for from 24 to 60 hours is favorable, providing other conditions are equally encouraging. A sudden fall of temperature, hut a continuously rapid and unchanged weak pulse without a true crisis is not to be interpreted as favorable. Prompt and complete crisis is always more favorable than is a slow lysis, for with the latter there is greater likelihood of complications. So-called unresolved pneumonia, diagnosticated because of the persist- ence of fever and other symptoms beyond the reasonable period for crisis and lysis, is as a rule due to some discoverable complication; empyema, abscess, thrombosis or tuberculosis should be suspected. Afebrile pneumonia in the aged is always serious; it is often of grippal BACTERIAL DISEASES 153 origin, and may be associated with arteriosclerosis or renal complications. In these patients the blood is likely to be surcharged with urea and waste products; there is great danger of sudden heart weakness and overpower- ing toxemia. There seems to be an antagonism between pneumococcemia and uremic conditions; when both are present, the temperature is not likely to be high, but death is usual between the tenth and fourteenth day, without marked respiratory embarrassment, but with great loss of strength and nerve force, and vasomotor paralysis. The Circulation I have already referred to the influence of pneumococcus toxemia on the heart and vasomotors in this chapter; the fight for life is successful or fails in accordance with our ability to favorably influence the circulation during the active stages of the disease. The tendency as the disease ad- vances is toward lowering of the blood pressure, weakening of the heart muscle, paralysis of the vasomotor centers in the cord, and is often mate- rially influenced by the mechanical obstruction in the pulmonary circuit and thrombosis of the pulmonary artery. The paramount factor in the prognosis of all forms of pneumonia is the circulation, i. e., the heart; upon its ability to resist the effect of the pneumococcemia largely depends the fate of the patient. The association of an enfeebled heart with dilated peripheral vessels is always a serious feature. The right heart weakness depends upon the extra burden thrown upon the right ventricle by the mechanical obstruction within the pulmo- nary circuit and the effects of toxemia; hence the prognosis is worse when the consolidation is extensive in the presence of dilatation of the right heart and its subjective symptoms. When such symptoms develop shortly before crisis, the heart may be bridged over the critical period. When with weakness of the right heart, the liver and spleen are en- larged and there is marked meteorism with albuminuria} casts and reduced quantity of urine, the outlook is bad. Cyanosis at any stage of the disease with air hunger, hurried respira- tions, rapid feeble pulse, and lowering systolic blood-pressure is among the most dreaded of all symptoms. Previous disease of the heart handicaps the pneumonic and always proves to be a factor with which we must reason in prognosis. The valvu- lar lesions, more particularly mitral insufficiency, are more favorable than are the degenerative processes as they affect the aorta and the myocardium. Mitral stenosis and aortic insufficiency are the least favorable of the valvular lesions with pneumonia. I have piloted many pneumonics to safe convalescence and complete recovery whom I had previously treated for organic diseases of the heart including valvular, arteriosclerotic and 154 SPECIFIC INFECTIOUS DISEASES myocardial changes. Much naturally depends in these cases on the asso- ciated conditions. The rule is, that the diseased heart offers less resist- ance to the infection than does the normal organ. Persistently rapid and small pulse from the beginning, with pro- gressively decreasing blood-pressure in the presence of constitutional and local symptoms is an expression of heart weakness. Such hearts, if crisis is early, may prove sufficient to serve through the infection but they always justify the greatest anxiety. Increasing rapidity of the heart on the third or fourth day, with at the same time evidences of fresh invasion, hurried and unimproved respira- tion with scanty albuminous urine, and deep involvement of the sensorium, is a serious symptom. Irregularity of a previously normal heart, arhythmia or intermissions before the crisis and during the first two stages of the. disease, are all to be interpreted as indicating the weakening of the circulatory apparatus; with or without an alternating pulse these conditions are alarming; they are evidences of myocardial involvement. The irregularities, intermissions, arhythmias and the erratic behavior of the heart during the period of convalescence, with a normal tempera- ture, and relief of the inflammatory process, usually with bradycardia, while they alarm the patient and the inexperienced attendant, yield after rest and without damage. These disturbances are frequent. Collapse during the acute stages of pneumonia is one of the dangers to be dreaded. This may be due to the sudden flooding of the blood with toxins or endotoxins, to sudden acute dilatation of the heart, pulmonary thrombosis, or embolism. Not all conditions of collapse in pneumonia prove fatal. Timely stimulation and absolute rest saves many lives. Often at the crisis there are associated symptoms of heart insufficiency, which in most cases are transitory. The Respiratory System Respiratory Symptoms.—It has been our experience that severe pain referable to the pleura of the inflamed lung which persists after the first 24 hours, with rapid pulse and thin bloody sputum, is evidence of a severe pneumonia. The pain is wearing, prevents sleep, robs the patient of re- sistance, and interferes with an already obstructed respiration. Dyspnea per se is dangerous when it depends upon diffuse bronchioli- tis, edema of the lungs, the consolidation of unusually large areas of lung tissue or myocardial weakness or degeneration, with dilatation of the right heart. Frequency of Respirations.—With dyspnea there is always increased frequency of respiration. Marked disproportion of the pulse and respira- tion is always unfavorable. With a pulse of 110 to 120 and respiration of BACTERIAL DISEASES 155 30 to 40 per minute without complications, and no other grave constitu- tional disturbances at the height of the disease, the prognosis is good. Respirations of 40 to 50 per minute with corresponding increase of the pulse and fall of blood-pressure, offer a doubtful forecast. Respirations above 50—from 50 to 70—with other symptoms of cor- responding severity, are found only in malignant cases which offer but slight hope. Rapid respirations early, and large moist and crepitant rales, and pro- fuse watery pinkish sputum, are all evidences of pulmonary edema and promptly lead to death. Evidences of obstruction and respiratory insufficiency which include with very rapid respiration the active playing of all accessory muscles of respiration, are always of grave import. Pye-Smith says “The bearing of the respiratory rate on diagnosis and prognosis may be summarized as fol- lows : An increased rate due to causes local in the lungs is important in diagnosis and unimportant in prognosis; and when it is caused by toxemia,, exactly the opposite is true.” Cheyne-Stokes breathing is always serious. It is evidence of deep poisoning and heart incompetence. Hypostatic congestion of the dependent lung is an almost constant accompaniment of pneumonia. In severe and fatal cases it is fully devel- oped, an expression of heart weakness and in turn throws an extra burden on the overtaxed organ. Sputum.—The usual appearance and average quantity of sputum are found in the favorable cases. Persistence of bloody sputum without improvement of constitutional symptoms, including fever and rapid pulse, demands a cautious prognosis. Excessive and thin sputum with marked dyspnea, hurried respirations and cyanosis, is proof of respiratory embarrassment and edema, making the outlook exceedingly grave. Orthopnea and superficial irregular respiratory movements, without ability to expectorate, large rales, noisy breathing, are evidences of the terminal stage of heart incompetence. Cough.—The most dangerous period of pneumonia includes besides, increasing heart weakness, the inability to cough with the accumulation of exudate and secretion in the bronchi. With unrelieved pulmonary edema these patients literally drown themselves. Free expectoration shows the strength of the patient and is of great assistance. We have referred to the sputum in previous paragraphs, especially to the significance of the thin prune juice pinkish sputum with evidences of edema and again repeat that it is always a dangerous symptom. 156 SPECIFIC INFECTIOUS DISEASES The Blood Carbon Dioxid.—It has been found that “in pneumonia the diminu- tion in the carbon dioxid content of the blood is a constant feature.” “Oc- casional cases, however, may fail to show low carbon dioxid” (Peabody). This observer further claims: “The carbon dioxid in the blood bears little definite relation to the severity of the disease, except that it tends to be lowest in severe cases and in the terminal stages of the disease. There is less deviation from the normal in short or mild cases.” Bacteremia.—We have already considered the significance of bac- teremia (pneumococcemia) on prognosis in this chapter and need not there- fore repeat at this point. Leukocytosis.—In no acute infection does prognosis depend more largely than in pneumonia on the protective powers of the blood. The assistance, of the leukocytes to combat the invading army of bacteria and nullify their toxins is demanded early (phagocytosis'). Hekton says: “The cure of pneumonia results from the destruction of the pneumo- cocci in the lungs and in the blood. This is accomplished by phagocytosis and also by extra cellular digestive processes. “The predominating general defensive reactions in pneumonia are leukocytosis and the production of antibodies for pneumococci, of which the opsonins are best known; and these appear to be specific for the group to which the infecting pneumococcus belongs.” In rapidly fatal cases Ilekton says the defensive reactions are inade- quate to destroy the pneumococci which persist and multiply in the lung and in the blood, while the free antibodies are absent from the blood. In cases which offer a good prognosis the pneumococci are destroyed when “antipneumococcal reactions reach a certain height.” With lysis there is a gradual, with crisis a prompt destruction of the pneumococci in the lungs and in the blood. “In both cases, but demon- strated more clearly in crises, there is an excess of antibodies in the blood.” The leukocytic count in pneumonia offers valuable prognostic data. With severe constitutional symptoms early and a high leukocytic count, the outlook for a favorable course is materially strengthened. Counts above 25,000 are under such circumstances encouraging. High leukocytic counts during the entire first week are favorable. In mild infections in which there are moderate constitutional symptoms, favorable facies and physical signs, the leukocytic count of 18,000 to 25,000 considered with all that the case offers, usually justifies a favorable prognosis. Severe infections which include marked evidences of cardiac toxemia with a low leukocytic count, possible tendency to leukopenia, offer only the gravest prognosis. BACTERIAL DISEASES 157 Severe constitutional symptoms with fair heart strength, often delirium with high leukocytic count (40,000 to 50,000) offer encouragement, but the prognosis should be guardedly given. Decrease of leukocytes with positive crisis is favorable. Unchanged leukocytic count with pseudocrisis does not influence the course of the disease. Rise in the number of polymorphonuclear leukocytes after crisis with febrile, movement or other symptoms, is always suggestive of some com- plication, usually empyema, plebitis, thrombosis, abscess or other non-tu- berculous process. Suspicion of a tuberculous complication is justified with fever or per- sistence of physical signs, failure to convalesce satisfactorily, and a low white count. Such cases may require a number of days before positive conclusions are reached. Conclusions.—Conclusions from the foregoing statements justify a bad prognosis in pneumonia in cases with a low leukocytic count or leukopenia. The average mortality in cases without leukocytosis is over 50 per cent; often higher. Cabot in 329 pneumonics found 32 with white counts of 10,000 or less; 30 of these died. The author’s experiences run parallel with these figures. The leukocytic count bears no relation to the extent of the consolida- tion, so far as clinicians have been able to observe. High leukocytic counts during the first day or two with rapid decided fall following is always grave. This proved to be true experimentally by Rosenow, Williamson and others. Pneumonics showing high leukocytic counts who die, do not yield to pneumococcus toxemia directly, but to some complication such as myocarditis, meningitis, septic or pyemic disease, pulmonary thrombosis, or some other secondary disturbance. Neutrophilic leukocytosis predominates in pneumonia; this begins with the initial chill and continues until crisis. With, or shortly before crisis, there is a decided fall in the number of the neutrophilic leukocytes. Pseudocrises do not as a rule show marked change in the leukocytic count. Complications of inflammatory and pyogenic nature are associated with high leukocytic counts; these include abscess, empyema, endocarditis, pericarditis, phlebitis, as well as metastatic parotitis, and a variety of less frequent complications. Eosinophilia is not present until the beginning of crisis; its appear- ance one or two days before crisis presages a favorable outcome (Raegeli). Lymphocytes are relatively increased before the crisis though there is an absolute reduction of these in the blood. The complication of ankylostomiasis by pneumonia at once reduces the existing eosinophilia. Leichtenstern found a drop of eosinophils to 6 to 7 per cent from 72 per cent. Warburg from 65 per cent to 0, and a return 158 SPECIFIC INFECTIOUS DISEASES of the eosinophilia with the recovery of the patient. Acute sepsis has the same effect. Myelocytes are found in moderately severe and grave pneumonia; they practically follow crisis (Haegeli, Tiirck, Schindler). The blood-plates are always increased in numbers. The French hema- tologists have proved an enormous increase of platelets following crisis (Crise hematoblastique). Fibrin is increased in the blood. Maegeli calls attention to the reduc- tion of the fibrin content of the blood in the absence of leukocytosis. Miller and Reed (J. A. Miller and M. A. Reed), in a study of the leukocytes in pneumonia, found in their series of 40 cases leukocyte counts varying from 15,000 to 20,000 in all cases excepting the 10 which proved fatal, in which the average of 27 counts was 21,040, while an analysis of the records of the leukocyte count in the 514 cases occurring in the 5 years—1904-1908—in the First Medical Division of Bellevue Hos- pital showed average counts of 20,444 for the patients who recovered, and 18,827 for those who died. From this the authors conclude that leukocy- tosis is as high in the fatal cases as in those which recover, a high leuko- cytosis indicating a very severe infection. They found also that the neu- trophils vary from 72 to 77 per cent in all classes of cases excepting in the very severe infections, where they averaged 81.8 per cent. (Their study of the Arneth differential neutrophil count, in which the neutrophils are classified according to the lobulation of the nucleus, showed an increase in the fewer lobed forms. Ho conclusions of clinical value are drawn from this finding.) Urobilin in the blood is probably evidence of interference with the liver function and the destruction of red blood-corpuscles; its appearance in the blood of pneumonics is unfavorable. Connor and Roper found that in fatal cases of pneumonia the bilirubin disappeared from the blood within 8 days of death and that urobilin appeared. The coagulation time of the blood is prolonged during the acute stage of pneumonia. A return of the time to normal is favorable, and is coinci- dent with convalescence. Dochez says, “There seems to be a simultaneous increase in the quantity of circulating fibrinogen. The lengthening of the coagulation time is probably due to an increased formation of anti throm- bin.” Tin's comes from the liver, and it is further held that “the stimulus to increased production of these two substances (fibrinogen and antithrom- bin) is due to the nature of the infecting agent.” The Nervous System The gravest pneumococcus infections are likely to cause severe symp- toms referable to the nervous system; there are exceptions to this rule. But few cases of pneumonia pass through the acute stages without some evidences of toxemia of the nervous system. BACTERIAL DISEASES 159 The headache of the early stage may often be very severe; its severity is in no way related to the gravity of the disease. Early delirium is not of serious import. Muttering during sleep is usually present, and bears no relation to the nature of the infection in most cases. Wild, active delirium with failing pulse, is often evidence of deep infection; it may continue until shortly before death and in many such cases there is a large and organized thrombus in the pulmonary artery. In alcoholics, there are almost always delirium and other evidences of alcoholic meningitis, with rapid respiration, albuminuria with casts, and death with irregular breathing in coma, after several days of the active manifestations mentioned. Convulsions in children during the first or second days of pneumonia are not often serious; they are of grave import when they occur late and are then due to toxic nephritis or to malignancy of the infection. In the adult, convulsions during any stage of pneumonia are of serious import. Pneumococcus Meningitis.—With convulsions and the Kernig symp- tom with or without positive information from examination of the lumbar fluid, pneumococcus meningitis must be suspected and an unfavorable prognosis should be given. We have no record of recovery in which the diagnosis of 'pneumococcus meningitis was positively established. Spinal Fluid (Lumbar Puncture).—In connection with the prognostic significance of the-symptoms of meningitis with pneumonia, we consider (a) meningismus and (b) meningitis. (a) Meningismus.—Meningismus is also known as meningitis sine meningitide, pseudomeningitis, and circumscribed infectious meningitis. The study of the spinal fluid and pathologic observations, prove that there is no “universal meningitis” in these cases but that the brain, cord and membranes are hyperemic and succulent. Here and there are small deposits of pneumococci. The spinal fluid contains. an occasional poly- morphonuclear leukocyte but no pneumococci. With meningismus the prognosis is comparatively good; meningitis may finally develop and change the complexion of the case. The condition is frequent in children, and at times causes the leading symptoms of brain fever in both children and adults during 24 to 48 hours before pneumonia is diagnosed. (b) Pneumococcus Meningitis.—The pneumococcus is the most frequent cause of pyogenic meningitis. The. diplococcus rapidly multiplies in the membranes of the brain and in the spinal fluid. The development of symptoms is prompt and the clinical picture clear. As already inti- mated the prognosis is absolutely bad. The spinal fluid withdrawn through lumbar puncture early (first 12 to 24 hours) may show no marked change, but soon (within 18 to 36 hours) there is increase of fluid, increased pressure (250 to 400 mm. and over), and albumin is found. The fluid is cloudy, it may be slightly purulent in 160 SPECIFIC INFECTIOUS DISEASES occasional cases; there are many polymorphonuclear leukocytes and an abundance of pneumococci. Culture experiments prove corroborative. Cerebral symptoms, including delirium, great unrest with mutterings in the pneumonia of the aged, is almost uniformly fatal. Postpyrexial Delirium.—The prognosis of the delirium following crisis, either during convalescence, or several weeks after recovery, which we have called, postpyrexial delirium is good as a rule. In some cases there were no mental symptoms during the acute periods of the disease in spite of hyperpyrexia, and postpyrexial delirium followed before the end of the first week of convalescence. The duration of the delirium varied. In children it continued in our cases from 2 to 5 days, in adults, aged between 30 and 45 years, from 3 to 6 weeks; in a few, with bad family histories, subacute or chronic mental disturbances developed. The latter sequel was found in our series to yield in almost all cases. The Urinary System Quantity of Urine.—In favorable cases the quantity of urine secreted continues considerably reduced, but there is not the great reduction found in the most malignant forms of the infection. In the most serious and malignant infections the quantity of the urine is reduced to but a few ounces. Albuminuria is an almost constant attendant of pneumonia; it is not always of serious significance. Unless careful and repeated examinations are made the foregoing statement will not be verified. Toxic nephritis shows abundant casts, marked reduction of the urine secreted, large albumin loss and the other characteristics of parenchyma- tous nephritis without many blood-cells. Nephritis adds to the dangers materially. Overpowering septic nephritis is more serious than are the other forms of kidney involvement. In all chronic nepliritides develop- ing pneumonia conditions of extreme gravity are presented; these include besides the cardiac toxemia, arteriosclerosis and the many associated lesions previously mentioned, upon all of which added infection can pro- duce only baneful results. Chlorid Excretion.—In most cases the chlorids are reduced, and re- turn at the end of the acute stage of the disease. Increase of the chlorid content may be interpreted as being favorable. Urea and uric acid offer no prognostic data. They are increased early, are often materially diminished before crisis, and increase within the early hours of the crisis or shortly after. Sugar.—Glycosuria may appear during any stage of pneumonia; in cases which were normal before infection it is usually transitory and does not recur after convalescence, neither does it interfere with the progress of the case. BACTERIAL DISEASES 161 With diabetes mellitus or diabetes insipidus the prognosis of pneu- monia is exceedingly grave. Most of these cases are atypical and present serious complications. Recovery is among the possibilities. The Skin The prognostic significance of herpes labialis is debatable. There are many who interpret the vesicular eruption favorably, others offer the opposite view or claim that it is without marked significance. The weight of authority is in favor of a favorable prognosis in the presence of herpes. Our conclusion from a study of pneumonias seen during the last 7 years proves that the majority of patients with herpes recovered. This subject is still sub judice. ISTo reliable clinician will ever offer prognosis based on the presence or absence of herpes vesicles. Free sweating with decided fall of temperature at crisis is always favorable. Excessive stveating with cyanosis and cold extremities, pinched facies, small pulse, rapid breathing, often associated with edema of the lung is almost always fatal. Gastro-intestinal System Vomiting' in children, occasionally in adults, does not persist as a rule and rarely interferes with the course of the disease: the same may be said of diarrhea. Membranous colitis is an infrequent complication but is always seri- ous. Meteorism which persists is of considerable importance; it interferes with respiration, throws added work on the heart, causes great discomfort by displacing the diaphragm and frequently prevents sleep. Hiccough is also wearing and unless controlled may increase the dan- gers of the infection. With alcoholics and with the asthenic types of the disease it is always ominous. Acute Dilatation of the Stomach.—Acute dilatation of the stomach due as has been demonstrated (Fussell) to constriction of the duodenum at the root of the mesentery, with probable primary involvement of the innervation, is one of the gravest complications of pneumonia. When it arises suddenly during the height of the disease it may promptly lead to death unless relieved. Sudden dilatation of the stomach with chronic valvular disease and pneumonia is almost always fatal. Prompt recog- nition of the acute dilatation of the stomach and the use of the stomach tube will remove the dangers due to this complication. Slight jaundice is not serious; deep jaundice with marked nervous symptoms is always grave (See Bilious Pneumonia). 162 SPECIFIC INFECTIOUS DISEASES Spleen The spleen offers no data of significance in the prognosis of the disease. It is not much enlarged; in only 35 of 100 cases was the weight above 200 grams (Osier). Hemorrhagic infarcts of the spleen with pneumococcus endocarditis or abscess, add to dangers already grave. Physical Signs The prognostic significance of the physical signs referable to the con- solidation must be interpreted in connection with the associated symptoms referable to the heart and vascular system separately. They offer but insignificant evidence of existing danger save in those cases where there is respiratory insufficiency with pulmonary edema and with far-reaching consolidation and atelectasis. The dangers of pneumonia are often out of all proportion to the extent of the physical signs. With central pneumonia there may be overpowering toxemia before the disease can be localized by the objective and positive manifestations of consolidation. Clinical Varieties of Croupous Pneumonia Afebrile Pneumonia.—We have already referred to the possibility of serious pneumonia without rise of temperature. These cases may lead to crisis just as do the febrile types of the disease. The association of nephritis with such infection and the influence of uremic poisoning we have already considered in this chapter. In old patients there is reason to fear for the outcome in these cases. Bilious Pneumonia.—In the grave cases there is deep jaundice, albu- minuria with casts, reduced and concentrated urine, cerebral disturb- ances ; these often include active delirium. There is, in most, infection of the bile passages; this may be of the mixed type (pneumococcus with either streptococcus, staphylococcus or other contamination). The added complication is a handicap. The mortality of our cases was about 35 per cent (this includes only those with deep jaundice and the clinical picture given in this paragraph). Pneumonia of the Alcoholic.—We have repeatedly referred to the pneumonia of the alcoholic and need not repeat. In our hospital experiences we have found that the majority of alco- holics who die with symptoms of meningitis, delirium tremens or other acute manifestations, show on post mortem examination the presence of pulmonary consolidation. Asthenic Pneumonia.—Friedrich Miiller has given a very clear clin- ical picture of asthenic pneumonia. In these asthenic types of the disease we find the subject reduced as a rule by previous disease; the pulse is BACTERIAL DISEASES 163 weak and small; the consolidation is usually limited; there is great unrest, marked delirium and many evidences of an atypical course. There may be no initial chill, and the sputum may never be rusty. The spleen is enlarged, pericarditis and endocarditis are frequent complications. En- demic influences are paramount. These cases, because of the adynamia and the multiplicity of complications offer an uncertain, often unfavor- able prognosis. Migratory Pneumonia.—The prognosis of migratory pneumonia con- tinues uncertain during long periods; the disease is exceedingly dangerous. There are repeated fresh invasions of lung tissue and in most there is added streptococcus infection. The duration of these cases varies. It may be 3 weeks, often longer, and occasionally the patient dies after several months of mixed infection. In some of these there is also malig- nant endocarditis; all with this complication die. Embolic Pneumonia.—Embolic pneumonia is often an expression of malignant endocarditis (pneumococcus or other infection). There are wedge-shaped infarcts; the symptoms are atypical, and the prognosis is grave. Influenza Pneumonia.—Influenza pneumonia has been fully consid- ered in the chapter on Influenza. Hypostatic Pneumonia.—Hypostatic pneumonia accompanies acute and chronic infections or disease in which there has been preceding hypo- static congestion. It always adds a large element of danger, and is often an expression of an insufficient myocardium. It is often a sequel of chronic disease in old people who have been bedridden during long pe- riods; often ends life after fracture of the hip, after operations in the decrepit, and in chronic brain and spinal lesions. Aspiration Pneumonia.—Aspiration pneumonia, due to the entrance of foreign substances into the lung, following ether anesthesia, or asso- ciated with paralyses—bulbar, glossopharyngeal—diphtheria, and other acute and chronic diseases, is serious if the associated condition is grave. The close study of the clinical history with the influence of the symptoms separately considered is needed to clear the horizon for prognosis. Pneumonia and Tuberculosis.—Pneumonia complicating tuberculosis is partially considered in connection with pulmonary tuberculosis. These cases include: I. Acute croupous pneumonia, in which the disease attacks an area of lung tissue, the greater part of which is the seat of infiltrating but latent tuberculosis. The prognosis is not necessarily bad; many under favorable conditions recover. II. Cases in which there is (a) an acute croupous or catarrhal pneu- monia in the immediate vicinity of tuberculous areas. The disease may run its course, terminate by crisis or lysis. There is usually no hemop- tysis. 164 SPECIFIC INFECTIOUS DISEASES (b) Chronic or subacute pulmonary tuberculosis in which pneumonia attacks distant parts of the diseased or previously healthy lung, in which there is no early hemoptysis, but in which the tuberculous process is actively progressive. The prognosis of these cases is bad. III. Cases in which there is mixed infection (pneumococcus and streptococcus) in which the acute pneumonic consolidation is added either to a latent or an active pulmonary tuberculosis. Hemoptysis is an early symptom of the acute exacerbation, or immediately precedes the pneu- monia, the latter depending on the aspiration of infecting agents from the seat of the original tuberculous infiltration, which is usually disor- ganized. The prognosis of this type is bad. I\r. Cases of acute croupous or catarrhal pneumonia with concurrent tuberculous infection. This complex is usually found in patients with lowered vitality resulting from childbearing, alcoholism, or unfavorable environment. In these patients there is in a short time disorganization of lung tissue, cheesy infiltration, coagulation necrosis, hectic fever, and death. The complications which influence the prognosis of pneumococcus in- fection not previously fully considered in this chapter are: (1) Pulmo- nary edema, (2) Gangrene of the lung, (3) Empyema, (4) Pleurisy (serous), (5) Bronchitis, (6) Bronchorrhea, (7) Abscess of the lung, (8) Emphysema, (9) Purulent infiltration of the lung, (10) Fibrosis of the lung, (11) Pericarditis, (12) Endocarditis, (malignant and be- nign), (13) Arthritis (suppurative and non-suppurative), (14) Suppu- rative peritonitis, (15) Otitis media suppurativa, (16) Purpura, (17) Neuritis (peripheral), (18) Metastatic parotitis. 1. Pulmonary Edema.—Pulmonary edema may develop early, when it literally drowns the patient in his own serum. Such cases are of the foudroyant type and die within the first 2 or 3 days of the disease. When pulmonary edema develops after the first stage of the disease, and is not promptly controlled it is amolng1 the most serious complications of pneu- monia. Pulmonary edema is always a life threatening complication. Re- peated reference has been made to its association with the clinical types in the previous pages. 2. Gangrene of the Lung.—Gangrene of the lung is not a frequent complication. Pye-Smith reports 37 cases in 7,868 pneumonics. When extensive it is usually fatal. When circumscribed, recovery followed in several of my cases; such recoveries are always slow. Some cases lead to long periods of sepsis; loss of strength and flesh is progressive, and death occurs after several months. 3. Empyema.—Pneumococcus empyema offers a more favorable prog- nosis than do any of the other infections which may cause it. Complications BACTERIAL DISEASES 165 Children develop empyema oftener than do adults. The incidence of this complication varies with different years and with different epidemics; the statistics are therefore unreliable unless the average covers several years. Such statistics of our cases show an average of 6 per cent in our pneumonias of the past 7 years. The early recognition of empyema and its prompt and radical treat- ment in all ages offers an excellent prognosis in the absence of other com- plications. This subject is fully treated in another chapter (See Purulent Pleurisy). 4. Pleurisy (Serous and Fibrinous).—Pleurisy following pneumonia is usually promptly relieved, if detected early. But few cases of lung inflammation pass to convalescence without more or less inflammation of the overlying pleura during the second or third stage of the disease. The prognosis in uncomplicated cases is good. In the fatal cases of pneumonia" pleurisy is found in over nine-tenths of all cases, but is not the cause of death. Unrecognized pleurcd effusion, which displaces the lung and surround- ing organs during long periods in which spontaneous recovery follows, may cause permanent damage because of adhesions and consecutive inter- ference with the functions of separate organs (See Serous Pleurisy). When pleurisy becomes chronic, there is always danger of fibrosis of the lung, i. e., final chronic interstitial pneumonia (See Chronic Inter- stitial Pneumonia). 5. Bronchitis and Bronchiolitis.—In old people and very young chil- dren bronchitis of the smaller tubes is often a serious complication. In adults, complicating bronchitis has less influence on prognosis than in other forms of the disease, more particularly bronchopneumonia. Most cases of croupous pneumonia have more or less bronchitis as a complica- tion. 6. Bronchorrhea.—Bronchorrhea may either precede or follow pneu- monia. Bronchial dilatations may harbor disease-producing organisms and lead to further complications. Many patients who have bronchor- rhea seem predisposed to repeated but limited croupous or catarrhal pneu- monic processes. Chronic bronchitis with bronchorrhea may, in the presence of acute pneumonia, particularly when there is associated emphysema, interfere with the overburdened organs of respiration and throw added work on the right heart. 7. Abscess of the Lung.—All of our cases of superficial lung abscess in which we made early diagnosis and treated radically, made satisfactory recoveries. Deep seated abscess of the lung is not frequent and is usually fatal; many of these cases are discovered post mortem. Multiple abscesses are found with mixed (pyogenic and pneumococcus) infection, are a part of an existing pyemia and are fatal (metastatic abscesses). Abscess of 166 SPECIFIC INFECTIOUS DISEASES the lung may lead to or may be associated with gangrene, and the outcome is grave. Superficial abscess may break into the pleural cavity, into a bronchus, into the mediastinum or pericardium. Rupture into the pleural cavity leads to pyopneumothorax. All of these accidents are serious. Ab- scess of the lung with empyema offers a less favorable prognosis than does the latter alone (See Empyema). 8. Emphysema.—We referred to emphysema in considering bronchor- rhea with chronic bronchitis. Emphysema may complicate acute pneu- monia involving healthy lung tissue, and is largely a compensatory hyper- trophy; it is physiological and does not influence the progress of the primary infection. 9. Purulent Infiltration of the Lung.—Purulent infiltration of the lung may occur during the stage of grey hepatization. It is held by some authors to be identical patholigically with abscess (Beitzke), and by many is considered to be uniformly fatal. Pye-Smith expresses the belief “that purulent infiltration need not be fatal, but may end in complete recovery’’ and holds further “that it is nothing more than an acute edema of the lung in a stage of grey hepatization, and that it marks the complete arrest of the process of resolution for the time being.” We have reason to be- lieve from our experience with conditions diagnosed as purulent infiltra- tion complicating pneumonia that the contentions of Pye-Smith are correct—that while the condition is serious, it is not necessarily fatal. 10. Fibrosis of the Lung.—Fibrosis of the lung following pneumonia is not frequent. The pathologic changes are identical with chronic inter- stitial pneumonia which is separately considered (See Chronic Pneu- monia). Probably deep pleural changes which become chronic are responsible for the connective tissue overgrowth. The condition is always chronic; patients may live during many years and usually die of intercur- rent disease, or tuberculization may follow. 11. Pericarditis.—Inflammation of the pericardium may with pneu- monia be either serous or purulent. The serous effusion is less serious than is the purulent. The latter is more likely to run an acute course, the former is often subacute or may merge into a chronic state. Pericarditis may be an early or a late complication; it is more fre- quent with inflammation of the right lung. Post mortem statistics prove the presence of pericarditis in 10 to 12 per cent of the pneumonias examined. Chatard found 35 cases of peri- carditis in 658 pneumonias at Johns Hopkins Hospital of which 31 died. These figures prove the great danger of the complication. Purulent pericarditis complicating the early stages of pneumonia is almost uniformly fatal. Pneumonics who live beyond the acute stage with pericarditis and effusion offer encouragement for radical surgical treatment. Myocarditis or myocardial degeneration is an almost constant accom- BACTERIAL DISEASES 167 paniment of pericarditis adding to its dangers. Acute dilatation of the ventricles with myocarditis and pericarditis is a frequent cause of sudden death. 12. Endocarditis.—Endocarditis may be either (a) malignant or (b) benign. Preexisting endocarditis always adds to the danger of pneu- monia. It is at once a serious handicap for the heart; it is unfavorably influenced by the toxemia and the mechanical obstructions—conditions with which it is less able to cope than is the normal heart. (a) Malignant Endocarditis.—The diseased heart valves invite the deposit of pneumococci, acute exacerbations of endocarditis result, 'pneumococcus endocarditis develops which may run an acute or exceed- ingly chronic course with multiple infarcts in the various organs of the body and which in the end kills the patient. We have not a single case of recovery of pneumococcus endocarditis to report in which the diag- nosis was positively confirmed by blood cultural methods (See Malignant Endocarditis). (b) Benign Endocarditis.—Endocarditis complicates between 6 and 10 per cent' of pneumonias, but a small per cent of these are of the malignant type, and the majority therefore yield to treatment. There are many associated conditions which influence the prognosis of all forms of endocarditis complicating pneumonia; among these are, as with pericardi- tis, the associated myocardial degeneration and vasomotor paralyses. All features must receive careful consideration before the clinician com- mits himself. It will always be wise to give guarded prognosis with all heart complications in pneumonia. 13. Arthritis.—In our experience suppurative arthritis has been so rare as to require but casual mention. The complication is more fre- quent in children than in adults. One large joint is usually involved which finally suppurates. The condition is grave and leads to death in one-half of the cases, or to permanent damage to the joint. When the complication is early it is most serious. Eon-suppurative polyar- thritis only occasionally complicates pneumonia; it may interfere with convalescence, rarely materially influences prognosis. 14. Suppurative Peritonitis.—Suppurative peritonitis is mentioned by Pye-Smith as having occurred in 22 of his 7,868 cases of pneumonia —0.3 per cent. We have never, in our experience met with a case. 15. Otitis media suppurativa.—Uncomplicated middle ear inflamma- tion is a frequent complication of the pneumonia of children; but few adults suffer. When radically treated early otitis does not influence the prognosis of the primary infection. Neglected cases or those overlooked may lead to sequeke; among thees are meningitis, septic or pyemic con- ditions, cerebral thrombosis, abscess of the brain and other distant disturbances. 16. Purpura.—Purpuric conditions which develop during the active 168 SPECIFIC INFECTIOUS DISEASES stages of pneumonia are always serious. In such cases the prognosis is exceedingly grave. Purpuric conditions which develop after the acute stages are either due to the malignant pneumococcus endocarditis (petechise, infarcts, etc.), or they may be an expression of a depraved blood state. If the latter con- dition is the cause of the symptoms, there are likely to he hemorrhages from mucous membranes and skin lesions; the prognosis is good, but convalescence is slow. When purpuric symptoms are due to septic emboli (malignant endocarditis) there are as a rule no hemorrhages from the mucous membranes, but infarcts into vital organs, including brain, kid- ney, spleen and lung, with characteristic symptoms. The prognosis is unfavorable. 17. Neuritis (Peripheral).—Multiple neuritis may complicate con- valescence; it was found in few! of our cases. Recovery is slow but cer- tain. In the few cases we have seen the four extremities have been involved. 18. Metastatic Parotitis.—Metastatic parotitis is considered in a sepa- rate chapter (See Metastatic Parotitis). With pneumonia it is always serious and is often associated with the more malignant infections, especially malignant endocarditis. There are no organs of the body which may not be involved during an acute pneumonia and complicate it. To consider all of the possible complications would lead us into an exhaustive study of the entire field of pathology (Jurgensen). With the data given in this chapter the lead- ing factors which influence prognosis are brought within the reach of the reader. Statistics and the Results of Treatment We quote from our article (Eisner): “Hospital statistics, which it may be assumed offer the only collective information available which shows the results of treatment, are misleading and often unjust. Neg- lected cases are found in all services and are numerous; many alcoholics are brought to our -wards moribund; not a few cases treated from the be- ginning of the infection in private homes without adequate nursing finally enter the hospital wards to die. All of these cases showing a high mortality are included in published statistics, and are received by the pro- fession and the lay world as representing the actual results of our fight against the disease. In my recent service at St. Joseph’s Hospital in Syracuse, we received into our wards 34 cases of pneumonia, of which 8 died; of this number 5 died within the first 24 hours following admission. Our published mor- tality was 23.5 per cent, whereas the results of treatment, or more prop- erly, the mortality of cases receiving hospital care during more than 24 hours, presented a more hopeful picture. Of the remaining 29 cases only BACTERIAL DISEASES 169 3 died, and of these, 2 were chronic alcoholics—a mortality of only 10.3 per cent. These statistics are repeated in the wards of all general hospi- tals year after year, and lead the thoughtful to the conclusion that the truth concerning the effect of treatment can be reached only after a thorough analysis of statistics and the grouping of cases.” It may be concluded that the rational modern treatment of pneumonia, including careful nursing, materially influence the prognosis of the disease. It is a mistake to subscribe to the ancient dictum that the healthy and active offer a less favorable prognosis than do the weak and sickly. The Influence of Prophylactic Vaccination It would seem that with pneumonia as with typhoid fever, we may hope that prophylactic inoculation will finally influence the frequency and, the course of the disease. The observations of Sir Almroth Wright definitely proved that preventive inoculation in the Premier diamond mine only 5 per cent of the inoculated natives contracted pneumonia as against 10 per cent of the uninoculated, and that the percentage of deaths was: inoculated 1 per cent, uninoculated 3 per cent. There are at the present time no evidences which prove that vaccine therapy influences the prognosis of actual pneumonia. 2. Bronchopneumonia (Insular Pneumonia, Catarrhal Pneumonia, Lobular Pneumonia, Desqua- mating Pneumonia, Secondary Pneumonia, Capillary Bronchitis) Bronchopneumonia is almost always secondary to preexisting bronchial catarrh; it is a catarrhal inflammation of the bronchioles with characteris- tic changes in the parenchyma of the lung, including exudation into the air cells which is highly albuminous, usually non-coagulable, containing desquamated epithelial alveolar cells, leukocytes and few erythrocytes. The desquamated epithelium undergoes fatty and cellular degeneration as the disease progresses. The exudate fills the air cells invaded. The alveolar walls are hyperemic and are infiltrated with round cells. The fibrin content varies. In cases following measles and diphtheria in chil- dren, fibrin is often present in large amounts wfith the cellular elements which justify the diagnosis of fibrinous bronchopneumonia. Primary bronchopneumonia is not frequent. Less than one-fourth of all cases are primary. This is probably a higher figure than would be justified if full histories were always obtainable. In children after the second year the prognosis of primary bronchopneumonia is relatively good. Younger babes show less resistance, but the prognosis cannot be considered absolutely bad (25 to 40 per cent). 170 SPECIFIC INFECTIOUS DISEASES The lesions, in contradistinction to the lobar form of pneumonia, are lobular, multiple, and invade both lungs. Confluence of islands of disease is frequent. Bronchopneumonia is a disease of early and of late life. The catarrhal inflammation of the bronchioles of influenzal origin is frequently followed by lobular pneumonia, and has been considered in the chapter on influenza (See Influenza). Lobular pneumonia is the characteristic inflammation of the lung which complicates diphtheria, scarlet fever, measles, whooping cough, typhoid and typhus fever, plague, bronchitis, bronchiolitis and other acute infections. Clinical data which are fully discussed in connection with pneumo- coccemia and lobar pneumonia are largely applicable in reaching conclu- sions for prognosis in bronchopneumonia, and to these the reader is re- ferred (See Pneumococcemia). Complications of Bronchopneumonia Bronchopneumonia is oftener complicated by atelectasis than is lobar pneumonia, and when large areas of lung tissue are collapsed, the prog- nosis is correspondingly bad. The prognosis must of necessity depend very largely upon the nature of the primary disease and the other factors to which full reference was made in the Section on Croupous Pneumonia, including: I. The malignancy of the infecting agent. II. The effect of the toxemia and the associated local lung lesions on the cardiovascular system. III. The resistance offered by the patient. IV. The extent of the pulmonary and associated lesions. (For full consideration see Pneumococcemia). Bronchopneumonia is in many cases an expression of pneumococcus infection; it may be of streptococcus, staphylococcus, meningococcus, mi- crococcus catarrhalis, influenza bacillus, diphtheritic, bacillus coli or other bacterial origin. Mixed infection is frequent; usually the pneumococcus is found with some one of the infecting agents mentioned in the preceding paragraph. Pneumonic plague has been separately considered (See Plague). The prognosis of bronchopneumonia must always depend upon the character and cause of the preceding disease or accompanying bronchitis, the virulence of the specific associated microorganism, and the nature of the inspired or aspirated substances which were paramount in causing extension of the disease. The cases of aspiration bronchopneumonia are included in a separate class, and the prognosis also depends upon the cause of the entrance of the foreign and the infecting substances. BACTERIAL DISEASES 171 Aspiration pneumonia with cerebral apoplexy, bulbar paralysis, diph- theritic paralysis, uremia, associated with tracheotomy or other operative measures, cancer of the upper air passages, is almost always fatal. Bronchial hemorrhage may lead to catarrhal pneumonia; the prognosis is usually favorable. Cases in which the exudate is hemorrhagic are associated with the most malignant infections and are always serious. The ability of children to resist bronchopneumonia is often surprising: better after the second year than before. Obese children, those with ra- chitis, the syphilitic, and the tuberculous, offer reduced resistance and cloud the prognosis. Conditions in children may be extreme, the picture may appear hopeless and yet full restoration to health may follow. Cya- nosis and extensive atelectasis are unfavorable features. Special symptoms offer the same relative prognostic significance in bronchopneumonia as in lobar pneumonia (See Lobar Pneumonia: Pneu- mococcemia). It may be added to what has been said that early high temperatures are not to be interpreted as necessarily serious, but late hyperpyrexia is always an expression of uncontrolled disease and makes positive prognosis impos- sible. Low temperatures, i. e., to 101° F. or lower, are often an ex- pression of weakness; are found at times in cachetic children, those who are exhausted and without resistance. The disease in young children is of longer duration than is lobar pneu- monia: it may last from 7 to 21 days. Protracted cases usually die. Relapse is frequent. The Significance of the Complications There are fewer remnants of disease and complications than in lobar pneumonia. The significance of the few which are found may be studied in the chapter on lobar pneumonia. Septic lesions are rare after bronchopneumonia. The bronchial nodes are often enlarged; they may become tuberculous or they may, as has been repeatedly suggested in the consideration of pul- monary tuberculosis (See Tuberculosis), hold a latent focus during many years which may finally lead to active disease. The prognosis of pneumonia is less favorable in children with measles, whooping cough, diphtheria and scarlet fever than in those who had simple bronchitis of the larger bronchi before the lung infection. Our mortality in private practice in children is not above 10 per cent. In hospital practice it is much higher, 12 to 30 per cent. Aspiration, ether pneumonia and pneumonia in children following the entrance of foreign substances into the lung are all exceedingly grave dis- eases. 172 SPECIFIC INFECTIOUS DISEASES The approach of bronchopneumonia may be expected in children when in the midst of an acute infection associated with bronchitis the respira- tions are suddenly increased, there is increased movement of the respira- tory and accessory muscles, the temperature shows a decided rise, and the pulse is correspondingly accelerated. In the aged bronchopneumonia is one of the most frequent causes of death. Statistics are of but little value because the primary conditions are often so serious that it is difficult to determine accurately their relative importance in the prognosis of separate conditions. It may be assumed, however, that in the aged, the secondary bronchopneumonia is the terminal complication which hastens death (See Influence of Age, etc.; chapter Pneumococcemia. With typhoid fever, long continued hypostatic congestion, adynamia, and often atelectasis, the prognosis continues grave, and the forecast un- certain during several days. Chronic pneumonia, bronchiectasis and emphysema are occasional se- quel of bronchopneumonia. Catarrhal pneumonia is more fatal than lobar pneumonia. The more acute the course, both in children and in adults, the better is the prognosis. The more extensive the inflammatory process, the greater is the danger to the patient. The combination of meningitis and catarrhal pneumonia offers only the most dismal prognosis. In reaching conclusions concerning the influence of the heart and vas- cular system the data given in connection with pneumococcemia should be studied. Marled leukocytosis is favorable, but blood pictures are less reliable than in lobar pneumonia because of the influence of the primary infections in most cases. The further considerations of the prognosis of bronchopneumonia is considered in connection with the many diseases which it may complicate in the separate chapters dealing with such diseases.

Erysipelas (Die Rose, Rotlauf) Etiology The Streptococcus Erysipelatis.—Erysipelas is an infectious, con- tagious disease caused by the Streptococcus erysipelatis, a strain of the streptococcus longus, also known as Streptococcus erysipelatos hemolyticus (Schottmiiller), which gains entrance to the lymphatic spaces of the skin through an abrasion and causes local inflammatory changes, sometimes suppuration, often general sepsis and other complications. The disease is likely to recur; there is in some people a remarkable susceptibility and vulnerability which makes them ready to develop erysipelatous inflamma- tions at short intervals, on slight cause, not infrequently when the standard of health is lowered. Port of Entry.—Excoriations of the shin about the nose, and an eroded nasal mucosa are the most frequent ports of entry of the streptococcus; hence facial erysipelas is the most frequent form of the disease. 174 SPECIFIC INFECTIOUS DISEASES Traumatism (surgical and non-surgical) causes'fewer cases at present than before the days of antisepsis when erysipelas was feared not only by the physician but more by the surgeon and obstetrician. Hospital wards, maternity and surgical, were at times of epidemics decimated by the infec- tion following operations and labor. The mortality in hospitals and public institutions at times of peace and during war in the past, has been alarm- ing, reaching from 7 to 25 per cent and higher, until at present owing to modern precautions the presence of erysipelatous infection in a hospital ward creates a strong suspicion of carelessness, which cannot always be charged to the attendants but should always be recognized as a preventable complication. Period of Incubation.—The period of incubation is short—not longer than from 3 to 4 days as a rule—though in the rapidly spreading and sthenic types of the disease it may be but 24 hours. Complications Influencing Growth of the Infection The more virulent and malignant cases, running a rapid course, are found in alcoholics and those debilitated by dissipation and chronic dis- ease. With cirrhosis of the liver and chronic nephritis, erysipelas is always a serious complication; also in the obese and those suffering from chronic heart lesions. Puerperal erysipelas is among the most serious complications of child- birth. The mortality varies in accordance with the virulence of the infect- ing strain, the resistance and age of the patient, the extent of the disease and the trauma, and the ability of the vasomotors and myocardium to with- stand the toxemia. It is never to be lightly regarded. Erysipelas of the newborn (umbilical) involving the skin and umbil- ical cord is often associated with phlebitis and offers a grave prognosis; most babes thus infected die. Erysipelas of the aged is always associated with great danger, greater when there is cardiovascular or renal disease coexistent. With diabetes and erysipelas the prognosis is almost always unfavorable. Local Manifestations The more extensive the local manifestations of infection, the more out- spoken are the constitutional symptoms. Tendency to migration of skin lesions is found in the less acute cases; the course of these is often tedious and convalescence, slow. Such cases often offer a serious outlook, they may complicate streptococcus tonsillitis due to milk infection or epidemics of streptococcus infection of unknown origin. Such a case we recently saw during an epidemic which spread over several townships in which the ini- BACTERIAL DISEASES 175 tial infection was tonsillar; later there were from 6 to 8 weeks of migra- tory erysipelas, in which the entire surface of the body was involved at various times, with final meningitis and death. Bloody vesicles with petechice and limited sloughs with other evidences of purpura or malignant endocarditis and infarcts, are unfavorable and present only in the gravest cases. Extension to the mucous membranes of the disease with edema of the glottis may lead to sudden death. Glandular enlargements in the neighborhood of the infected skin need cause no alarm. General Manifestations Circulatory Disturbances.—In the active and robust with a clean 'pre- vious history, the hyperpyrexia of the third and fourth days in the absence of other alarming symptoms such as heart weakness, need not dis- courage the attendant. In these cases there may be active delirium and a rapid pulse, and yet the prognosis in over 95 per cent of cases proves to be favorable. The height of the temperature may mislead the clinician in occasional £ases, for he may fail to recognize the danger in the aged or feeble, in which there is but slight fever but characteristic asthenia. Such patients bear erysipelas badly. The pulse is rapid according to the height of the fever and may be arhythmic at times during the first week. Arhythmia and dicrotism with hyperpyrexia and meningeal symptoms present a complex which should cause anxiety during several days. Unless there be purulent meningitis or other serious complication and the disease is limited, over 90 per cent of these patients finally recover. A small, rapid, soft and thready irregular pulse, with other evidences of malignancy or complications, is always alarming and should lead to a guarded forecast. Whenever in the course of erysipelas there are evidences of endocarditis the possibility of the malignancy of the latter must be considered. Com- plicating streptococcus endocarditis offers an unfavorable outlook. Dry pericarditis is not of itself fatal. Purulent pericarditis is a part of an existing pyemia or general sepsis, and is found only in the gravest cases. Systolic mitral murmur due to relative muscular insufficiency, with or without accentuation of the second pulmonic sound, disappears during or shortly after convalescence and is followed by normal heart function in almost all cases. Non-malignant endocarditis as a rule, when a complication, leads to the recovery of the patient, though there may be some evidences later of 176 SPECIFIC INFECTIOUS DISEASES its previous existence in deformed valves (murmurs) and compensatory change (hypertrophy). Respiratory System.—Hurried respiration, with or without evidences of lung involvement (pneumonia, bronchitis, etc.) has in our experience been a symptom found with malignancy and is exceedingly grave. Rapid respiration does not always indicate the presence of pneumonia. Pneumonia, particularly with alcoholism, is likely to prove fatal in the presence of erysipelas. Purulent pleurisy, associated with migratory erysipelas, has proved to be a serious complication, though not all cases are fatal. Albuminuria is not of serious import, it is present in most cases at the height of the infection. In 10 per cent of our cases there were evidences of nephritis; among these the mortality was low. Occasionally bloody urine was found without interfering with a favorable issue. Purulent meningitis is an occasional cause of death in erysipelas. Metastatic parotitis (see Metastatic Parotitis), is evidence of sepsis and malignancy. Blood.—There is, in the severest cases, enormous albumin loss from the blood which is in direct proportion to the gravity of the disease. In severe cases there is enormous destruction of red blood-corpuscles. A count of 3,000,000 in a previously normal blood is of grave significance. Poikilocytosis in these unfavorable cases is striking. Large hemoglobin loss is also an early evidence of the gravity of the disease. Leukocytosis is usually present in cases of erysipelas, is largely de- pendent upon complications, mixed infections, etc.; alone it is of small prognostic value. Conclusions The prognosis of the average case of erysipelas is good; the mortality varies from 3 to 5 per cent. The leading causes of death in our experience have been cardiac tox- emia, purulent meningitis, general sepsis, malignant endocarditis (strepto- coccus), mixed infection, alcoholic meningitis and delirium tremens, sinus thrombosis, exhaustion due to repeated re-infection at short intervals. When erysipelas develops in the midst of other acute infections, as with typhoid and with surgical diseases, or after surgical operations, the prog- nosis is grave. Our experience with non-altoholic patients predisposed to the disease, who have been repeatedly infected at long intervals, has been uniformly favorable. In spite of repeated fiery attacks they have recovered. One of these is now alive, over 80 years of age, after 50 years of recurring erysip- elas. BACTERIAL DISEASES 177 IX. Epidemic Cerebrospinal Meningitis (Ubertragbare Genickstarre) Epidemic cerebrospinal meningitis is an epidemic or sporadic inflam- mation of the. cerebrospinal membranes due' to the Meningococcus of Weichselbaum (1887) ; characterized by symptoms referable to the brain and cord, in which the diagnosis can be positively vei'ified by the presence of the Meningococcus of Weichselbaum in the withdrawn lumbar fluid. Mortality There is scarcely a year when the disease fails to claim its victims in most cities and countries of the civilized world. The mortality is greatest during April and May, the number increasing during years of endemics and epidemics. Thus in a period of ten years before the introduction of the Flexner serum, there were in the city of Syracuse 175 deaths due to cerebrospinal meningitis, and 499 deaths due to non-epidemic meningitis.

The disease claims the larger number of its victims from the homes of the poor, though the disease may exist under favorable conditions and in sanitary homes. During epidemics, the limited number of cases and the absence of continuous extension are often surprising, as was also the high mortality, before the introduction of the present method of treating the disease. The disease is often held within a narrow precinct of a city or a corner of a township. When epidemic meningitis visits country districts the same remark- able limitation of its ravages is noticed in the small number attacked. These facts are well illustrated by an experience on board the U. S. re- ceiving ship Minneapolis, as reported by Surgeon Stokes. The ship was overcrowded with 1,450 men on board at the time of the outbreak, yet only 23 cases developed; of these 6 died—an unusually low mortality of 26 per cent. Clinically and experimentally it has been demonstrated that pneumo- coccus, influenzal and other forms of cerebrospinal meningitis are more virulent than are those of epidemic origin due to the meningococcus. Pneumococcus meningitis is almost uniformly fatal. Of 68 cases, 61 died during the first day of the disease, while Netter who reports these figures, says that only one-third of his meningococcus cases died. Huebner says uthe benign nature of the meningococcus as compared with the virulence of other meningitis-producing germs, accounts for the comparatively few cases during epidemics, their ready control with the subjugation of the germ.” Occurrence Flatten’s statistics corroborate tbe data which I collected in New York State (Eisner), and prove that the disease is rare after the for- tieth year. Flatten's statistics, gathered during 1905-1907 in Kattowitz, showing ages of patients, are as follows: BACTEKIAL DISEASES 179 0 to 5 years 559 eases 5 to 10 “ 248 “ 10 to 15 “ 72 “ 15 to 20 “ 47 “ 20 to 25 “ 15 “ 25 to 30 “ 14 “ 30 to 35 “ 7 “ 35 to 40 “ 3 “ 40 to 45 “ 2 “ 45 to 50 “ 2 “ 50 to 55 " 5 “ 55 to 60 “ 1 “ 60 years and above 0 “ I found that when the disease did occur in adults, it was often invited by long continued worry and mental strain. Sporadic cases run much the same course as do those of epidemic origin; there are no differential features. Bacterial and cultural tests only, give the information which insure' safety and the protection to which the public is entitled. Second attacks of the disease are not likely to occur. Councilman (quoted by Eisner), found but five cases in which the disease did repeat itself in the same patient. Oppenheim does not believe that one attack gives immunity. Factors Influencing the Severity General Symptoms.—There are unexplainable factors which modify the severity of both the epidemic and sporadic disease during different years and influence its course. All degrees of severity are found with both. For purposes of prophylaxis and prognosis it cannot be repeated too often that the same bacteriologic cause is paramount in both epidemic and sporadic cases. Early coma or its persistence after the end of the first week is an unfavorable symptom. Early glycosuria with coma or with marked delirium is unfavorable. Deafness is not to be considered among the ominous symptoms so far as life is concerned. It is present in a large proportion of cases and leads to permanent deafness in from 15 to 25 per cent of cases. Suppurative ophthalmia, panophthalmitis with perforation, is found in severe cases with mixed infection (4 to 5 per cent). Optic neuritis is a serious complication, present in 17 per cent of Jochmann’s cases, and in those who recover often leads to blindness. Unfavorable conditions are persistence of coma, involuntary discharge of urine and feces, rapid emaciation, increasing tympany, hyperpyrexia, rapid small pulse, sudden heart weakness with subnormal temperature. The facies of the patient, unlike any other disease, not easily described, 180 SPECIFIC INFECTIOUS DISEASES offer a picture which impresses the clinician at once and from which he can promptly reach conlusions for prognosis. The pulse and temperature offer nothing characteristic other than the acceleration of the former and the elevation of the latter. As death ap- proaches the pulse becomes exceedingly rapid—due to vagus paralysis. Hyperpyrexia with rapid pulse is usually a fatal combination. The. urine, usually secreted in good quantities, may be albuminous, and glycosuria is not uncommon. The former is not serious; the latter with high fever and deep invasion of the sensorium does not justify a favorable forecast. Not all cases with glycosuria die. The knee jerk is absent in one-sixtli of all cases. In one-tenth this phenomenon is absent to return as convalescence approaches. The varia- tion in the behavior of the reflexes in different cases proves that these follow no rule and offer little for prognosis; the sensorium is often so pro- foundly involved as to make the tests valueless. Striking, extreme opisthotonos with marked muscular rigidity is always an evidence of active and serious meningitis. The relief of muscu- lar rigidity and included opisthotonos, with brightening of the mind are always encouraging. Marked cutaneous hyperesthesia with or without the Kernig symptom, is always suggestive and is most pronounced in serious cases. Herpes facialis unusually frequent and profuse in Germany, is less frequent in the United States than are the erythemas and purpuric erup- tions (petecliise, etc.). Herpes is of no prognostic value. Petecliise are more ominous. Large cutaneous hemorrhages and bleeding from mucous membranes are evidences of malignancy. Early convulsions in children are not always of serious import; their persistence however is always grave. Tonic spasm limited, without full convulsions, is characteristic of the early stage of “postbasic meningitis.” (Lees and Barlow). These should all be considered cases of cerebrospinal meningitis and offer a bad prog- nosis. Trousseau s macule is neither of great diagnostic nor prognostic value. There are but few data referable to other organs, including kidney and spleen, which stand out as prognostic aids. Albuminuria is frequent, not significant; nephritis is rare, the spleen is not materially enlarged. The Kernig symptom is an early manifestation; it is as early as opis- thotonos and is late to disappear. It is present in between 90 and 95 per cent of all cases of epidemic cerebrospinal meningitis. The persistence of the Kernig phenomenon is of considerable value in diagnosis and prog- nosis in cases where the correct diagnosis was not suspected during the first week of the disease. As a rule, it is not needed to make the diagnosis; it is found with all forms of meningitis. If it persists, it should always lead BACTERIAL DISEASES 181 to the suspicion of cerebrospinal meningitis and for safety, the spinal fluid should he examined bacteriologically. Foudroyant Cases.—There are foudroyant cases in which the victim is suddenly overpowered; coma and malignant toxemia are prompt; and death may follow in the course of from 12 to 48 hours before the diagnosis can be made. We see fewer of these cases now than formerly, but occa- sionally they are encountered, usually early, or at the height of the epi- demic. Hyperpyrexia has been a bad feature of some of these cases. Sudden death in the midst of cases in which the prognosis has been held sub judice, is not infrequent. Such cases we have all met in the past and it is unjust now to charge these to the use of the serum or to any form of treatment. We have no definite cause to assign for some of these deaths, but would in explanation, quote Tourdes: “The disease is distinguished by the slowness of its cure and the rapidity of its fatal issue.” This dictum was advanced during the period preceding the introduction of the Flexner serum. Cases also foudroyant, meningitis siderans, are among the more fatal, and run their course unless controlled by treatment in from 4 to 6 days. If these patients finally recover, there are positive evidences of improve- ment after the second or third day. The sensorium gradually clears; tem- perature which is usually high shows decided remission; the cutaneous hyperesthesia is less; and the pulse shows increasing tone. With these changes, the blood picture and character of the lumbar fluid is also changed. Opisthotonus and rigidity, as already mentioned, are materially relieved also. In all cases of the disease the prognosis is not encouraging if improve- ment is not decided before the end of the second or early in the third week. The addition of other acute infections is always unfavorable, more par- ticularly pneumonia, scarletina, endocarditis, pericarditis and pleuritis. The interstitial myocarditis (toxic) of foudroyant cases adds enor- mously to the danger. The tonsils harbor meningococci, and from this port of entry the infection is often spread. The normal nasopharynx is antagonistic to the onward march of the Weichselbaum diplococcus. Chronic Cases.—Chronic cases with purulent deposit in the ventricles of the brain, bathing the cord also may persist during from 4 to 6 weeks— even longer—with marked symptoms, including rigidity, Kernig symptom; the sensorium may clear; some symptoms including fever may also im- prove, but with persistently high pulse, increasing weakness, final return of fever, and aggravation of all conditions, (mental and physical) these patients, usually neglected from the beginning, die. It is not at all unusual to find so-called chronic and subacute cases gradually mend, and in the end make full recoveries. Some of these how- ever escape with sequelae which handicap them throughout life. The chronic cases may end in hydrocephalus. 182 SPECIFIC INFECTIOUS DISEASES Progressive hydrocephalus dependent on epidemic meningitis is among the most unfortunate and fatal sequelae of the disease. In these cases the disease may continue during weeks—not infrequently months. Changes are found in the ependyma; there is a persistence of meningococci in the ventricles of the brain, “in much diminished numbers and of reduced viru- lence” (Koplik). As already stated the chronic cases, i. e., hydrocephalus, may present a clear lumbar fluid; meningococci may appear to be absent, but cultural tests show their presence. The marked emaciation of these patients is characteristic and has claimed the attention of all clinicians; they look like reconcentrados when next to each other in the hospital wards. The prognosis of these cases is bad, and when they do recover a variety of sequeloe may follow besides those already mentioned, including permanent mental alienation, persistent cephalalgia, vertigo, loss of memory, ataxia, contractures, etc. Abortive Cases.—Abortive cases end in the course of a few days fa- vorably, after but few symptoms and without sequelae. Most of these cases are found late in epidemics of the disease. Blood Picture.—The blood picture of epidemic cerebrospinal menin- gitis offers valuable data for diagnosis and prognosis. Rusca has made a very extensive study of this subject. During the early stage in all cases, there is marked leukocytosis (10,000 to 45,000) ; polymorphonuclear increase is greatest, while the behavior of the lymphocytes is not always the same; in some cases there is increase, in others a reduction. As the disease advances and where the condition is serious, there is at once an increase of neutrophilic leukocytes; improvement of acute condi- tions is at once followed by a decided fall. There is lymphocytic increase with each improvement or favorable turn of the infection, whereas a decided fall is promptly noted with added complication of serious moment. Curtius and Rusca agree that the blood picture of cases with measle- like eruption proves the contention of the former, that such cases offer a favorable prognosis. Hemorrhagic exanthemata offer an unfavorable blood picture and are often foudroyant. Returning eosinophilia is always favorable and is found during con- valescence. Eosinophilia is usually absent in serious and malignant cases, and is never present during the terminal stage of cerebrospinal menin- gitis ; the latter statement is true also of mast cells. The blood picture of cerebrospinal meningitis is of greater prognostic than diagnostic value; for the latter, we must always rely upon lumbar puncture. Lumbar Puncture.—Lumbar puncture gives positive diagnostic infor- mation as well as valuable prognostic hints. The fluid in average cases is cloudy, and escapes under abnormally BACTERIAL DISEASES 183 high pressure. Where there is purulent and thick effusion, the first few drops may be thick—“pussy”—after which the fluid is thinner, but re- mains milky or clouded. If there is acquired hydrocephalus and the condition is advanced to the subacute or chronic stage the fluid may be clear, but still the pressure is high (180 to 220 mm.). The fluid usually offers positive bacteriologic and cytologic evidence. The centrifugalized fluid shows abundant polymorphonuclear leukocytes and lymphocytes. With a negative result (bacteriologically) and the absence of meningo- cocci with positive symptoms of cerebrospinal meningitis, repeated exam- inations of the fluid are necessary, and will lead to the correct diagnosis. It is not uncommon to find the first examination negative, the second positive. Herter placed himself with those who believed that “lumbar puncture, more particularly the appearance of the cellular exudate in the early stages of acute cerebrospinal meningitis” is of prognostic significance. “The presence of degenerated leukocytes, containing few microorganisms while many cocci are seen to be extracellular, points to feeble powers of resistance on the part of the leukocytes and hence to a bad prognosis.” It is further held that the persistence of well preserved leukocytes, showing many intracellular diplococci (indicating active phagocytosis) and the absence of many extra cellular microorganisms, indicate good powers of resistance and a better prognosis (other conditions being comparable) than in the former case.” Jochmann makes a suggestion, which seems important: that in suspected cases in which the first lumbar puncture fails, bacteriologic examination of the pharyngeal content will be likely to show the presence of the meningococcus. The presence of sugar in the cerebrospinal fluid may prove of some diagnostic and prognostic value in both cerebrospinal meningitis and tuberculous meningitis. This subject has received considerable attention of late, more particularly from Jacob and Connall. The latter gives the results of the examination of the cerebrospinal fluid for sugar in 133 cases of cerebrospinal meningitis, all stages of the disease included. ITe con- cludes that sugar is absent from the fluid during the acute stages of the disease. During1 the chronic periods sugar is present. “It may be said, however, with certain reservations, that the reappearance of the sugar is an indication that the disease is in process of cure.” Jacoh agrees with Connall that “in cerebrospinal meningitis sugar is absent (from the fluid) in the acute stage, but may return in some degree as the infection recedes.” Complications.—Mixed infection with either sporadic or epidemic cases is frequent; the meningococcus may have abundant companionship before death or recovery. This is always serious. Cases of cerebro-spinal meningitis with pneumonia offer only the most doleful forecast. SPECIFIC INFECTIOUS DISEASES 184 Meningococcus pneumonia may complicate cerebrospinal meningitis. In the presence of both of these conditions, i. e., pneumonia and cerebro- spinal meningitis, the meningococcus is present in 80 per cent and the pneumococcus in 20 per cent of cases (Eisner quotes Councilman, Mallory and Wright). Metastatic joint changes were found in a number of our cases, and when present early aroused suspicion of arthritis and pyemia. In one of our cases a woman, age 24, presented with arthritis limited to both ankles and profound meningococcus infection; she died in the second week of the disease. These cases are usually of mixed origin and demand a cautious forecast. Deafness often follows otitis media suppurativa, though the labyrinth may be involved without a single auditory symptom, until the patient awakens, or days after the beginning of convalescence it is noticed that the hearing is growing gradually less acute. In some cases patients lift them- selves from the acute delirium or period of unconsciousness with defective hearing, from which they may never recover. A large number of deaf mutes are found to have had epidemic cerebrospinal meningitis. Moos, quoted by Ormerod, found of 64 convalescents from cerebrospinal menin- gitis that 38 were deaf mutes; 20 were absolutely deaf, and 32 had a staggering gait. Both blindness and deafness offer a bad prognosis for return of func- tion if improvement is not prompt. Persistence beyond 3 moiiths of symptoms without improvement argues strongly against restoration later. The Influence of the Flexner Serum on the Prognosis of Meningococ- cus Cerebrospinal Meningitis There never will be a time when the prognosis of the disease will fail to be influenced by the virulence of line infecting agent. In spite of this fact, which has been discounted in the impartial consideration of the re- sults obtained, the profession is agreed that the Flexner serum is a remedy of undoubted value and that it has reduced the mortality of the disease, from 70 to 25 per cent. Indeed in some epidemics before the use of the serum, the death rate was 80, and it has been above 90 per cent. In some epidemics in which foudroyant cases were common 95 per cent died. Oppenheiin reports in one epidemic (Silesia) 3,102 cases with 1,789 deaths. Koplik says “the Flexner serum has given the disease a prognosis in epidemic periods equal to that of lobar pneumonia, and in sporadic cases even a better prognosis than the pulmonary affections.” He says further: “In sets of sporadic cases the outlook is not worse than in any of the ordinary affections of an infectious nature in childhood.” The prognosis during early life will continue to be influenced by the difficulties of early diagnosis and respiratory complications. BACTERIAL DISEASES 185 The delay of a single day or even 12 hours in very young children is often fatal (Koplik). Koplik in a series of 400 cases collected by him found a mortality of 50 per cent in 22 patients of 1 year and below, 42 per cent between 1 and 2 years. In Koplik’s service at Mt. Sinai Hospital, of 15 patients below 1 year, 10 died—66 per cent; of these 15, 2 injected on the fifteenth day recovered and 1 injected the seventeenth day was discharged improved, 1 on the twenty-first day was cured, as was 1 injected on the twenty-ninth day. 1 injected on the third day died. Of 12 patients between 1 and 2 years of age injected, 6 recovered (50 per cent) ; 1 of these injected on the second day of the disease died after an illness of 14 days. Among the causes of failure, virulence of the infecting strains, closure of the foramen of Magendie, adhesions preventing the entrance of the serum from the cord to the subarachnoid space above, late lumbar punc- ture (diagnosis), are included. Flexner’s statements are always concise and are accepted as absolutely reliable. We find in his report of 1,295 cases in which intraspinal injec- tions of his serum were given, 70 per cent of recoveries. In those in- jected within the first 3 days of the disease the mortality was but 18 per cent; injected between the fourth and seventh day, the mortality was 27 per cent, and those injected later 36 per cent. 125 children less than 12 months’ old were injected, and 50 per cent were saved. Of these, 5 were injected early and all were saved. “Reduction in mortality of cerebro- spinal meningitis due to the serum is from two-thirds to three-quarters of the average percentages, occurring in the same periods and places among patients not subjected to the specific treatment” (Flexner). These fig- ures tell their own story. Besides the enormous saving of life by the serum, we must add that by its use, the course of the disease is shortened and its sequelae are limited.

Whooping-cough (Pertussis, Keuchhusten, Coqueluche) Whooping-cough is an infectious contagious disease of early life, due probably to the Bordet-Gengou bacillus; it is characterized by catarrhal inflammation of the respiratory tract, a paroxysmal cough, and a “whoop” which is a long-drawn inspiratory movement coming at the end of several separate convulsive coughs. The disease occurs in epidemics usually, but is also sporadic; such unexplained infections are not infrequent and occur in all communities. Most children have had pertussis when they reach their tenth year. One attach usually produces immunity. Female children are always at- tacked in larger numbers than are males. Cold weather seems to invite the disease; complications are then more frequent than during warm weather. Negro children show a much larger fatality when infected than do whites. Uncomplicated whooping-cough leads to recovery after passing through three stages, unless as rarely happens, the case is of the abortive type: 1. Catarrhal stage. 2. Spasmodic stage. 3. Stage of recession (decrementi). Pertussis is the cause of many serious complications and deaths. While the disease, per se, as already suggested offers an almost uni- formly good prognosis, its sequela; make it an infection to he feared, and one which stands out in bold relief as a leading cause of death in early life. “It exceeds diphtheria and scarlet fever in gross mortality” (Osier). The average duration of whooping-cough is between 6 and 8 weeks. In children less than 2 years of age the prognosis is exceedingly grave, because of the complications. Infants suffering from rachitis and syph- ilis, or other constitutional disturbances, are prone to develop serious complications with whooping-cough because they offer but little resistance. The average mortality of whooping-cough is between 5 and 6 per cent. Voit reports a mortality of 25 per cent during the first year of life in BACTERIAL DISEASES 187 whooping-cough; from 1 to 5 years, 4.8 per cent; and from 6 to 15 years, 1.1 per cent. Complications Unfavorable surroundings invite complications and add enormously to the dangers of young children. Convulsions at any time during the course of whooping-cough are of serious import and unless due to errors of digestion, trivial or transitory causes, are ominous. When convulsions are due to sudden cerebral lesions (cerebral hemorrhage, tuberculosis, thrombosis), the prognosis is as a rule unfavorable. To these latter complications, we will again refer. Children who have enlarged lymph nodes need to be protected against all fresh infections, particularly pertussis and measles; for with these added diseases, there is always danger of complications, and with lowered vitality, tuberculization is to be feared. The most serious and numerous complications of whooping-cough are the catarrhal inflammations of the respiratory tract, the invasion of the bronchioles and air cells, causing bronchopneumonia. One-seventh of all cases of bronchopneumonia of early life are secondary to whooping-cough. It is often surprising to note the enormous resistance of children in the presence of far-reaching bronchopneumonia. During several days no forecast of value can be offered in the individual case. During this pe- riod children may continue desperately ill, and in spite of a complex of symptoms, which in the adult would warrant an unfavorable prognosis, they make happy recoveries. We have learned never to give up a child with bronchopneumonia for we have been agreeably surprised in cases where there seemed to be but the faintest glimmer of hope. These cases of bronchopneumonia are always secondary and are due to mixed infec- tion as a rule (pneumococcus and streptococcus). Hyperpyrexia with rapid heart action and symptoms referable to the nervous system in the presence of bronchopneumonia are always grave, and demand the greatest circumspection before a prognosis of any value can be offered. The youngest children are most likely to contract pneumonia and other complications. Nurslings offer a high mortality with pneumonia (95 per cent), and when attacked promptly die. When in the midst of whooping- cough fever develops, with increased respiration and the pulse correspond- ingly rapid, respiratory complications are to be expected; with such symptoms bronchopneumonia is most frequent. Rachitic children, those who have tuberculous (“scrofula”) tendencies in the presence of second- ary pneumonia, as in uncomplicated whooping-cough are non-resistant; in these, the mortality is very high. The duration of bronchopneumonia depends on the frequency of re- lapses, which are common and are due to fresh insular invasion. 188 SPECIFIC INFECTIOUS DISEASES Tuberculous complications with pertussis are surprisingly frequent, as has been proved by post mortem examinations; the bronchial nodes are the most frequent seat of deposit. In these cases there are often long periods of fever and relapsing bronchopneumonia; or in occasional cases children recover with latent deposits. Pulmonary tuberculosis is also frequent in those who die of whooping- cough. Neuroth makes the unqualified statement, that “tuberculous disease of the lung is practically never absent in children who have died of whooping-cough.” Latent deposits following whooping-cough may be- come active years after the acute stage and may lead to death (See Tuberculosis). Chronic cough, due to bronchiectasia, may continue during many years; may or may not be complicated with tuberculosis—making prog- nosis doubtful. Emphysema which may be present during the stage of spasm usually disappears without causing damage to lung tissue. Lobar or croupous pneumonia is not sufficiently frequent to demand consideration. Increased intravenous pressure and associated nutritive changes in the walls of the blood-vessels may cause hemorrhages into the conjunctiva, from the nose, mouth, bronchi, ear, or into the skin during the paroxysmal stage—all of which are transitory and do not often influence the prognosis unfavorably. Influenza complicating wdiooping-cough adds an element of danger; complications are more likely to follow, and pneumonia is foremost among these. The same is true of the influence of other added infections (measles, diphtheria and varicella). Dilatation of the heart with moderate hypertrophy of the left ventricle may result in cases where paroxysms are severe and frequent; but these conditions yield after convalescence and sufficient rest. Only rarely have heart lesions in the previously healthy been the cause of sudden death. Convulsions due to trivial or transitory factors in uncomplicated cases have already been mentioned; when convulsions are due to complications leading to organic and central changes, the prognosis is exceedingly grave. Cerebral hemorrhage offers an unfavorable prognosis; it may lead to death or to permanent paralysis. Hemiplegia may improve but does not as a rule disappear entirely. Paralyses of central origin lead to permanently reduced function in most cases; though marked improvement may follow, life itself is unin- fluenced. When paralyses are associated with bulbar symptoms the prog- nosis so far as life is concerned is bad. Ocular hemorrhages usually yield, only rarely is sight permanently affected. In occasional cases, spinal complications include symptoms of mye- BACTERIAL DISEASES 189 litis, poliomyelitis, Landry’s paralysis; in all the prognosis is the same as in the uncomplicated diseases of the nervous system. Constitutional disturbances, anemia, chlorosis, asthenia, chorea and faulty digestion fol- lowing pertussis all yield under rest and rational treatment. Blood Cima found whooping-cough, as the result of his investigations of the blood, associated with leukocytosis very early in the disease (18,000 to 22,000). The higher the leukocytic count the more severe the disease. The youngest children show the greatest increase of leukocytes and those cases in which there are mixed infections and complications. Other data offered by the blood are of no value for prognosis. Conclusions A history of whooping-cough is more frequent in choreic than in other children. In considering the prognosis of whooping-cough we are conscious of the fact that there are with this, as with all other infections, marked dif- ferences in the virulence and character of separate epidemics; that chil- dren react differently to the infection, that seasonal influences are of paramount importance, and finally that environment, as already suggested in this chapter, is a factor of the greatest prognostic significance. Trous- seau believed that the prognosis of whooping-cough was enormously in- fluenced by the numoer of paroxysms and concluded that more than 60 daily, justified a bad prognosis. References Cima.

Gonococcus Infections ( Gonococcemia, Gonorrheal Sepsis) It is not within the province of this work to consider the prognosis of local changes in the urethra, vagina, or in the eye, caused by gonococcus infection. There are occasional septic conditions which are dependent upon the entrance of gonococci into the blood, in which there are prompt evidences 190 SPECIFIC INFECTIOUS DISEASES of constitutional disturbance, and to these we refer in considering the prognosis of gonococcemia. The most frequent clinical pictures include 1. Gonococcus endocarditis. 2. Gonococcus arthritis (gonorrheal rheumatism). 1. Gonococcus Endocarditis Ahmann, Thayer and Lazear were among the first to isolate gonococci from the blood in gonorrheal endocarditis. The clinical manifestations of gonococcus endocarditis are variable. We have referred to this subject in our consideration of septic conditions, also with malignant endocarditis (See Septic Endocarditis). There are cases which are not associated with joint symptoms; these are in the minority. As a rule there is monarthritis; there may be 'polyarthritis. Soon the physical signs of endocarditis are added. The disease may be either of the (a) typhoid, (b) pyemia (intermit- tent), or (c) irregular type. (a) The Typhoid Type.—In the typhoid type the fever is continuous with slight morning remissions. The appearance of the patient is charac- teristic of the typhoid condition. Physical signs are positive, both sides of the heart are often involved; the right side oftener than with rheumatic or non-malignant endocarditis. The pulse is rapid and feeble, the sensorium is more or less disturbed; in some cases there is wild, in others, low muttering delirium; albu- minuria is almost constantly present, which often denotes septic nephritis. (b) Intermittent or Pyemic Type.—Occasionally the typhoid type merges into the intermittent after a day or two; sometimes there is a longer afebrile period; after a period of intermittent fever following, there may be a return to the typhoid state. Gonorrheal endocarditis of the intermittent or pyemic type is likely to be of longer duration than is the typhoid type. With intermittent fever the periods of remission vary. In some cases the periodicity of an intermittent malarial fever is observed; in other cases the chills and fever recur at irregular intervals during a long period—every 3, 4 or 5 days—always with profuse and weakening sweats following, and often with delirium. The other attend- ing conditions, including albuminuria mentioned in connection with the typhoid type, are in evidence. There are cases in which we have been deluded by long periods of freedom from fever and other symptoms; in such cases from 7 to 10 days have intervened without any subjective complaints, sometimes longer, when without prodromal symptoms the patient suddenly had a chill and the typical cycle followed. BACTERIAL DISEASES 191 The intermittent may merge into the typhoid or irregular type of the disease. Under these conditions the usual course of the disease includes rapid exhaustion and the typical picture of septic fever, from which the patient rarely rallies. (c) Irregular Types.—Irregular types are not infrequent with endo- cardial invasion. Gonococcus endocarditis may begin with irregular symptoms; the temperature may continue erratic during several days, after which the patient may fall into a typhoid condition; or the pyemic intermittent type may continue in the ascendency. The behavior of the irregular type of gonococcus endocarditis may mislead the clinician and the gravity of the disease may not be appreciated. Cases with irregular fever and other anomalies may include periods of varying length during which the intermittent type predominates, from which the patients fall into a typhoid condition, or there is return to an erratic and irregular behavior. In some irregular types there is hyperpyrexia following a single chill which invites degenerative myocarditis, and death is not long postponed. Petechiae are found in most cases of gonococcus endocarditis and are of great diagnostic and prognostic value. Their presence with the pre- vious history of gonorrheal infection and physical signs of endocarditis clinches the diagnosis and justifies only the gravest prognosis. Hemorrhagic infarcts into lung, brain, spleen or kidney complicate many cases. Once the diagnosis of hemorrhagic- infarct is positive, an unfavorable forecast may be given. The Blood.—Leukocytosis is a constant attendant of gonococcus endo- carditis; we have failed to gain any facts from blood-counts which influ- ence prognosis. In the more chronic and subacute cases there is increas- ing anemia. Our average leukocytic count was between 18,000 and 25,000. Blood cultural methods give positive results in over 70 per cent of endocardial infection. Gonococcus endocarditis may follow at any time while gonococci are present anywhere in the body. In occasional cases gonococcemia follows shortly after infection; in other cases 4 weeks or even a longer time may intervene. As we have already intimated our clinical material includes no case of recovery where the diagnosis was confirmed by blood cultural methods (See Septic Endocarditis). Recoveries have been reported by others and Jochmann contends that the prognosis of gonococcus endocarditis is the most favorable of all of the malignant endocarditis, and that recovery has followed in a few cases in which gonococcemia was positively proved by blood-cultures. The other prognostic data given in connection with our consideration of malignant endocarditis (See Septic or Malignant Endocarditis) are applicable also to gonococcus endocarditis. Complications.—With gonococcus endocarditis, pericarditis and myo- 192 SPECIFIC INFECTIOUS DISEASES carditis often occur. Pericarditis has complicated one-fourth of all cases; myocarditis many more. Sudden and overwhelming symptoms of toxemia in cases following within 7 to 14 days after gonorrheal infection are always promptly fatal. These cases may show no endocarditis. Pneumonia, pleurisy or abscess of gonococcus origin are found post mortem in some of these. Mixed infection complicates one-fifth of all cases. 2. Gonococcus Arthritis (Gonorrheal Rheumatism) So-called gonorrheal rheumatism when uncomplicated, in the absence of endocardial infection, offers a good prognosis for life; slow return of the involved joint to normal is the rule. Permanent damage to the joint often results, the swelling and stiffness may remain during many months, while anchylosis is a frequent sequel. Pains and swellings recur after exposure, or with the changes of the season. Cold and wet weather is unfavorable and increases all symptoms, often during months and years. Gonococcus arthritis is always rebellious to treatment. Most cases are monarticular, the knee and ankle are the seats of predi- lection. Polyarthritis usually causes constitutional disturbances, includ- ing fever, delirium and at times albuminuria. Suppuration may follow but is relatively rare. Relapses are frequent, provoked by insignificant factors and recurring acute gonorrheal infection. Most cases are chronic, even the mildest gonococcus arthritis shows remnants of invasion during months, often years, in either subjective or objective symptoms or both. Modern vaccine treatment has seemed to modify the course of gonor- rheal joint infection in some cases, but cannot be said to be a specific against the disease. Arthritis complicates from 2 to 4 per cent of gonococcus infections. References Ahmann, Thayer & Lazear. Mohr & Staeh liv. 1911, i, 697. J. Exper. Med., New York, 1899, iv, 81-116. Eisner (H. L.).

Bacillary Dysentery Dysentery is an infectious disease showing inflammatory and ulcera- tive (necrotic) lesions of the large intestine; usually endemic or epi- demic; characterized by frequent bloody and mucus stools, more or less tenesmus, constitutional disturbance, and in some forms, a strong tend- ency to secondary suppurative hepatitis (liver abscess). There are two varieties of dysentery: 1. Bacillary dysentery due to any one or more of three strains of the bacillus dysentericus: (a) Shiga-Kruse bacillus. (b) Flexner bacillus. (c) Y bacillus. 2. Amebic dysentery (Amebiasis) due to the Entameba histolytica (Loesch 1875, Koch 1883, Schaudinn). Amebiasis is considered in an- other chapter (q. v.). General Considerations BACILLARY DYSENTERY The Bacillus.—The Bacillus dysentericus (Shiga) resembles typhoid and colon bacilli very closely, is easily cultivated, there is no sporulation, and it is negative to Gram stain. The several species (Flexner, Y, and Shiga) all cause the same lesions, are morphologically similar, and all grow alike in culture media. The Flexner and Y bacilli produce indol in bouillon culture in a few days, the Shiga-Kruse does not. There are other differences which need not concern us in our special task of prognosis, included in differences of agglutinations, etc. Occurrence and Mortality.—Convalescents, patients and the appar- ently well, may he carriers and spread the disease. It is spread by man; his stools are the most important factor. The future clinician will prob- ably never have the experiences with dysentery that some who are active to-day had in the past. Modern sanitation, if practiced, can never again lead to such ravages as this epidemic disease has caused. Let the student of medical history familiarize himself with the data collected by Wood- ward which stands to-day, with clinical and pathological records as one of the most complete and painstaking medical works of the past century. Macgregor says: “In the tropics dysentery is a destructive giant com- pared to which strong drink is a mere phantom.” Wherever there is overcrowding, in camps, prisons, hospitals, asylums, during times of endemics large numbers are afflicted and in the past the mortality has been alarmingly high. 194 SPECIFIC INFECTIOUS DISEASES Woodward’s statistics show that during our Civil War there were 259,071 cases of acute, and 28,451 cases of chronic dysentery. To the latter number, the increasing pension rolls during the past 40 years would unquestionably add many. Dysentery in Japan shows a mortality of 26.5 per cent. Epidemics of dysentery in Hew York State (central) mentioned in this chapter in connection with malarial infection of bacillary origin, claimed less than 10 per cent of those infected. Symptoms The lesions which concern the clinician are an inflammation of the mucous membrane of the large intestine with strong tendency to ulcera- tion and destruction of tissue. In some cases, there is superficial loss of the mucosa with diphtheritic deposit (diphtheritic dysentery). Ulcers, according to the severity of the case, may he single or multiple. Entire areas of mucous membrane in grave cases may slough; in the milder cases the lesions are more limited. The incubation period of bacillary dysentery is from 2 to 7 days. During this period there are usually no alarming symptoms unless pa- tients have been weakened by previous disease, and if there are no anoma- lies the second stage is safely reached. Between the third and fifth days of the disease the character of the stool changes. In severe cases the stools are small, bloody; mucus may be mixed with blood; they are less fecal than earlier. Tenesmus and tor- mina, with the enormous frequency of movements, weaken the patient. In grave cases there is marked reduction in the quantity of urine secreted, albuminuria and casts, and there may be complete suppression. In the most serious infections the thirst is distressing, muscular exhaustion extreme, there may be vomiting of small amounts of mucus, intolerant stomach, hiccough with sunken abdomen. Hiccough is not favorable; with subnormal temperature it is ominous. As a rule the mind remains clear even in fatal cases; there are but few nervous symptoms save great unrest and inability to sleep because of the frequent stools and tenesmus. Frequent small bloody or blood-mucous stools with tenesmus, great thirst, suppression of urine, tormina, small rapid pulse, drawn and pinched expression, sunken eyes, cyanosis, sub- normal temperature, cold extremities, include the leading features of ■’.he most serious dysenteries. Temperature does not offer data for prognosis; in serious cases there may be subnormal or normal temperature while slight rise is of no value. Favorable cases may show several degrees of fever. Bacillary dysentery requires from 2 to 4 weeks before convales- cence is reached. Children, the aged, the feeble, the underfed, and the dissipated, offer BACTERIAL DISEASES 195 less resistance to bacillary dysentery than do the active during mature years, and those who have a good resistance. The tendency of bacillary dysentery is to recover. Convalescence is slow, and relapse promptly follows errors of diet. Relapses may last several weeks and merge into chronicity. Gangrenous dysenteric colitis is a grave complication and with symp- toms of sepsis, albuminuria or suppression, extreme exhaustion or collapse leads to death in most cases. Bacillary dysentery is less likely to produce the numerous irregularly shaped and undermining ulcerations, the deep submucous invasion so characteristic of the amebic type. The prognosis is naturally more favor- able in bacillary dysentery after the disappearance of acute symptoms than in the amebic form, because of fewer complications, more particu- larly the absence of suppurative hepatitis. Complications The dreaded abscess of the liver is not a complication of bacillary- dysentery. Buchanan reports 1,130 cases with but one abscess of the liver, and Hassler and Morgenroth assert that if present the abscesses are multiple, unquestionably septic metastases. (Coli bacilli and streptococci were found in the pus.) We had no experience with liver abscess in connection with the epi- demics of dysentery in New York State. So far as we know we have met but one case of abscess of the liver following dysentery and that came from the south and was clearly amebic. Rheumatic pains and joint swellings follow or are associated with acute dysentery in about 3 to 5 per cent of all cases These yield to treatment without leaving any permanent disability in most cases. An occasional complication referable to the heart may prolong the period of convalescence; these are very largely cardiac neuroses. Endocarditis, valvular defects and myocardial weakness have in isolated cases influenced the progress of patients. Bradycardia and tachycardia may persist during several weeks, but usually yield without recurring if the patient rests sufficiently. Those who have had the largest experience with dysentery report an occasional neuritis, paraplegia, hemiplegia, monoplegia, paralysis of a single group of muscles, in occasional cases a prolonged period of neuras- thenia. The peripheral neuritides offer a favorable prognosis; the outcome of the other paralyses must depend upon the underlying cause. Neuras- thenia yields slowly to treatment. Suppurative parotitis is a complication of the graver form of dysen- tery as is also empyema; both complications add to the dangers of an al- ready alarming infection. 196 SPECIFIC INFECTIOUS DISEASES Chronic nephritis occasionally follows acute dysentery. Chronic bacillary dysentery follows only in a small proportion of acute bacillary infections. Following the cases which developed during the Civil War there were a larger number of so-called “chronic diarrheas.” Some of these were mild and easily controlled by diet, some were less tractable, and many veterans are still living who developed the opium habit from the taking of the “black drop” to control their symptoms. These patients may live for years and die of the disease, or after long periods of drain they die of exhaustion. As with most epidemic diseases the severity of dysentery epidemics is variable. The Shiga-Kruse strain causes more severe symptoms than do the Flexner or Y bacilli. The first mentioned strain seems to cause more profound constitutional disturbances than either of the other two— the prostration is greater and the number of movements more frequent; hence the mortality is also larger with Shiga infection. Jochmann claims that with Shiga-Kruse infection the death rate is 10 to 15 per cent, with the other strains from 0 to .5 per cent. Sporadic cases as met in hospital and private practice in the United States offer a good prognosis. Reference See Amebic Dysentery. XIII. Malta Fever (TJndulant Fever, Mediterranean Fever, Neapolitan Fever) Etiology Malta fever is a specific infection closely resembling septicemia, due to the Micrococcus melitensis of Bruce (1886) which rages on the islands of the Mediterranean and along its coast; it is characterized by undulatory febrile relapses, excessive sweating, symptoms of arthritis, marked rheu- matic pains and enlarged spleen. The disease has at various times been found in Texas. The disease is now known to be due to the drinkinc of vncoolced goat milk which is charged with the organism of Bruce. The tendency of the disease is toward chronicity or a subacute course, the aver- age. duration being 120 days. There are occasional malignant infections in which the disease runs a rapid course to a fatal termination; these at present are exceedingly rare. The statistics of the Malta garrison show 2,229 cases, with a mortality of 77. The discovery of the cause has reduced the number of cases, so that its occurrence is now comparatively rare; boiling the infected milk prevents the spread of the disease. The period of incubation is from 6 to 10 days. BACTERIAL DISEASES 197 The diagnosis is easily corroborated by modern blood cultural methods and characteristic agglutination. Symptoms The fully developed picture of the disease resembles the typhoid condi- tion very closely; in severe cases the heart muscle shows weakness, pulse may be small and intermittent, there may be edema of the lungs; pneu- monia is an occasional complication. The temperature which follows a short period of malaise may mount to 105° F., but after a few days there is decided remission, evident improvement of all symptoms, after which evening exacerbations become persistent with progressive anemia, malaise, asthenia and enlarged tender spleen. Basset Smith called attention to the reduction of the leukocytes and their phagocytic power. There is painful swelling of the joints and often swelling of the testes. Patients grow progressively weaker during these periods which continue 2 or 3 weeks and which are followed by profuse sweating, but they bear the depression well; they then fall into an afebrile period which is soon fol- lowed by evening rise of temperature, and may continue with characteristic zigzagging of the curve during long periods. Bruce contends that one attack produces immunity. Manson and Bas- set-Smith deny this contention. The tendency is toward recovery. The mortality is not above 2 per cent. In exceptional cases early heart weakness may cause collapse and death; there is no stage of the disease which may not he complicated by sudden cardiac asthenia, edema of the lungs, or pneumonia. The. agglutinating power of the hlood is of great prognostic signifi- cance. Values above 1 to 300 are favorable; decided fall indicates earl} relapse. Prognosis References Bassett-Smith.

Asiatic Cholera (Cholera asiatica) History Asiatic cholera is an epidemic disease due to the comma bacillus (Koch 1883), and is always spread by an infected water supply. The disease was first authentically described by Jessor in 1817, who probably 198 SPECIFIC INFECTIOUS DISEASES observed it during the preceding year in Bengal; it has been endemic and epidemic for ages in India, the delta of the Ganges never being entirely free. Tscharaka, the Esculapius of India, and his pupil Sucrata who lived long before Christ and recorded their observations in northwestern India, gave a classic description of the disease. The first large outbreak of the disease on the European continent was early in the nineteenth cen- tury. There have been six large cycles of the disease recorded in modern medical literature: I. 1817 to 1823 in Asia and Africa. II. 1826 to 1837 in Asia, Africa, Europe, and America. III. 1846 to 1862 in Asia, Africa, Europe, and America. IV. 1864 to 1875 in Asia, Africa, Europe, and America. Y. 1883 to 1896 in Asia, Africa, Europe. VI. 1902—mild—Asia and Africa only As can be seen from the foregoing data, the United States has suffered several times, and its last experience with the disease was in 1893 when it was brought to the port of Yew York on several transatlantic steamers; but owing to the perspicacity of the health authorities with the concerted action of an intelligent and well organized profession, it failed to gain a foothold on American soil. Symptoms Infection of the alimentary canal of animals can be produced by neu- tralizing the gastric juice with sodium carbonate and the use of opium to prevent intestinal peristalsis. The disease presents severe symptoms of gastro-intestinal disturbance, watery discharges, associated weakness due to depletion and endotoxemia, with, in the severe cases, suppression of urine and other secretions, shrink- ing of tissues, great prostration, collapse and other symptoms resembling acute arsenical poisoning. The blood in the severe cases becomes viscid because of the sudden and great loss of serum, while in severe cases the specific gravity may reach 1,070 or higher. In considering the prophylaxis and prognosis of cholera it is unsafe to ignore the influence of the carriers of comma bacilli in producing the dis- ease. There is a surprising difference in the virulence of comma bacilliJ hence during an epidemic, rapidly fatal, serious and mild cases may be found at the same time and bacilli may be present in the intestines of nor- mal individuals, without causing symptoms. Cholera causes greatest havoc in districts where sanitation is faulty and masses are crowded together under unfavorable conditions. BACTERIAL DISEASES 199 In offering a prognosis three stages must be considered: 1. The stage of diarrhea 2. The cold or algid stage 3. The stage of reaction 1. The Stage of Diarrhea.—Diarrhea may begin toward the end of incubation in some cases in which patients previously had gastro-intestinal disturbances, but usually during the period of invasion. This stage may continue from a few hours (12) to 2 days. In severe cases the movements are frequent, large and watery, asso- ciated with marked muscular enfeeblement, small thready pulse, and at once the evidences of depletion with evident loss of weight, pinched facial appearance, pointed prominent nose, sunken eyes, dry skin, great thirst and reduced secretion of urine. The persistent vomiting with these symp- toms adds to the danger. There is no way of stimulating or nourishing the patient except through the skin—the large intestine is also intolerant. The pulse grows weaker and smaller; there is feeble systolic force with decided fall of blood pressure to 60 to TO mm., mercury: At times there is delir- ium. During this stage, however, the mind may remain clear, and death is likely to result. In the more favorable cases the stools become less frequent, the vomit- ing is more easily controlled, and the urine secretion is increased. Cyano- sis, cold extremities, rapid pulse and sudden urinary suppression, usually lead to death. Decided fall of temperature (3 to 5°F.) with any of the above men- tioned alarming symptoms during the first stage is dangerous. The dryness of the tongue and throat which leads to the vox cholerica is not necessarily of grave import; though present in serious cases. The small amount of albuminous urine in the more serious cases is loaded with hyalin and granular casts. In this and all stages of the dis- ease, the urine offers valuable indications for prognosis. The prognosis is good, in proportion to the ability of the kidneys to withstand the ravages of the disease; hence the quantity of urine secreted becomes a paramount factor in prognosis. 2. The Cold or Algid Stage.—If the prognosis is grave, the patient grows worse, urine scant, albuminous, or entirely suppressed; the appear- ance is cadaverous; the stools continue watery, large and frequent; the body is cold ; the skin is greyish-colored, in most severe cases cyanosed; the eyes sunken, uncovered and fixed; the pulse small and scarcely perceptible; coma is deep; almost complete analgesia exists; death usually ends the scene between the second and fifth day. If the case is likely to terminate favorably, the patient slowly bright- ens ; the temperature gradually rises from the low mark to which it fell; the pulse is fuller and perceptible; and the urinary secretion—the. import- 200 SPECIFIC INFECTIOUS DISEASES ant factor—is increased, clears itself; and the tongue is moister; the stools less frequent; and vomiting is relieved. In cases with a severe first stage, the patients often die early in the algid stage. The cramping of muscles is a painful and weakening symptom in many cases. With nephritis uremia is supposed to be a cause of many symptoms, including convulsions, also a serious complication. Relapses in cases progressing favorably are not infrequent; this is often true where dietetic errors have been made. Cholerine, a mild form of the disease, may develop from a preceding diarrhea; the symptoms may include many of the more severe forms of the disease, but the prognosis is usually good. These cases are recognized by their more benign course, less collapse, though they may show cardiac weakness, marked renal invasion with less albumin loss than in the severe cholera. Occasional cases of cholerine may develop true Asiatic cholera. In the Hamburg epidemic this proved to be true in 50 per cent of cases. Cholerine is also caused by comma infection. 3. The Stage of Reaction.—In occasional cases sudden death early in the third stage follows a severe case which may have improved slightly in the algid stage. Great weakness and apathy with cyanosis and cold extremities are unfavorable. Fall of temperature after rise in the second stage, early in the period of reaction with the symptoms above mentioned, is unfavorable. Patients falling into a typhoid condition with elevation of tempera- ture, without marked coma, abundant urinary secretion, and sufficient heart strength to give a fair systolic contraction, offer a more favorable prognosis than do those, with the symptoms mentioned in the two preceding paragraphs. Convalescence may begin suddenly with the appearance of an erythe- matous eruption and febrile movement. Coma in the third stage of the disease is always unfavorable, and likely to be due to uremia and endotoxemia. The Blood Picture.—Enormous relative increase of red blood corpus- cles is unfavorable; this may reach one to two millions per c. mm. (polycy- themia). Leukocytes are markedly increased in unfavorable cases— 50,000 and over (Biernatzki). In unfavorable cases the alkalinity of the blood is reduced because of the loss of sodium. The height of the specific gravity is of some prognostic value. Patients infected toward the end of epidemics usually develop anoma- lous types of cholera, but in all of these the prognosis is relatively good. BACTERIAL DISEASES 201 Complications Complications are always of serious moment. Among the complications are gangrene, croupous pneumonia—rarely the catarrhal form—hypostatic congestion and edema of the lungs, paroti- tis, intestinal ulceration, diphtheritic infection of the intestines, uterus, bladder and vagina. Abortion which causes prompt death of the fetus offers an unfavorable prognosis for the mother. Secondary enteritis—chronic catarrh—may follow recovery from the acute symptoms. Following recovery, there are as a rule no permanent kidney lesions. The following general conclusions may be accepted in connection with the data already offered: Conclusions Cholera infection without outspoken symptoms offers a favorable, prog- nosis. These patients are, however, subject to the sudden development of severe symptoms on slight cause. Patients between 6 and 25 have the best chance for restoration to health. Individual resistance as an important factor in prognosis. Fever at any stage of the disease is more favorable than subnormal temperature. Brightening of the intellect with a good skin reaction, and erythema- tous eruption is favorable. Past experiences justify placing the mortality of epidemics between 30 and 80 per cent. Alcoholics offer a grave prognosis. The period of immunity produced by the disease is exceptionally short. References Biernatzki. Deutsch med. Wchnschr., 1892 & 1896. Jessor. Handb. der Tropenkrankh.

Plague {Bubonic Plague, Pest) Plague is an epidemic disease due to the Bacillus pestis (1894, Yersin and Kitasato), a non-motile, Gram-negative microorganism, showing well marked polar staining which may cause either 1. Bubonic plague 2. Septicemic plague 3. Pneumonic plague 4. Pestis minor 202 SPECIFIC INFECTIOUS DISEASES History Plague has been known since the third century of the Christian era; there are references in medical history which create a strong suspicion that the disease raged before that time, hut information is not authentic. The Orient was the original home of the plague, which, during the centuries has invaded the continent of Europe repeatedly and has claimed thou- sands of victims. The plague which visited Europe during the reign of Justinian in the Second half of the sixth century was unquestionably due to the same infec- tion which caused the plague of Milan in the seventeenth century, which has been graphically discussed and illustrated by Fletcher, proving igno- rance of the cause of the disease, save as Pare positively declared that an invisible agent produced it, thus foreshadowing its bacterial origin. The “Black Death” of the fourteenth century invaded all of the then known world, destroying twenty-five million souls, and it is held by Ilecker that one-quarter of the earth’s population fell victims to the disease. Dur- ing the fifteenth and sixteenth centuries bubonic plague never entirely disappeared from the continent of Europe—there were epidemics of vary- ing severity. With the end of the seventeenth century the disease limited its ravages on the continent to Southeastern Europe until 1878 to 1879, when Astrakhan (Russia) was infested. During the early nineteenth cen- tury Europe continued free from plague. The epidemics of Hong Kong (1894), Bombay (1896), and Manchuria (1910 to 1911) include our latest experiences with the disease. It spread to many countries, includ- ing the West Indies and the United States; San Francisco and California suffered most. The virulence of plague is demonstrated by the experience of Toulon in 1721 when of its 26,000 inhabitants 20,000 were stricken and 16,000 died. Infected rats and rabbits introduce the disease indirectly through fleas which serve to inoculate man by their bites. Fifty per cent of the rat fleas belong to the variety pulex clieopis, which rarely bite man—hence the com- parative immunity of the human race; neither does the ceratopliyllus fas- ciatus bite man freely. “The common brown rat is not a house resident to any extent, so that conditions in England are not very favorable for epi- demic prevalence” (Osier). The same is true of the United States and of a large part of the European Continent. In the United States and Eng- land we have no conception of the terrors of plague without recalling the frightful mortality of the disease in India where in 5 years there have been, in three provinces almost 54 million deaths attributable to the dis- ease. In the remaining provinces of India, numbering 200 million souls, there have been 2 million deaths (Osier). At present, plague is endemic along the slopes of the Himalayas, in Bombay and its surroundings, in East African Uganda and the southeast of Russia. BACTERIAL DISEASES 203 Mode of Entry It is easy to understand how the unfortunate barber of Milan con- veyed the disease from person to person by his infected unguent, which must have carried the pus directly from the ulcers; for it requires only a slight abrasion or microscopic break of the skin to furnish the point of entry for the bacillus—possibly friction alone is sufficient. The lymphat- ics promptly transmit the infection and the destructive effect follows. The bacillus may also be. inhaled through the respiratory organs and provoke pneumonia. Whether through the lymphatics to the blood-stream or the lung, the blood is soon surcharged and a condition of profound and fatal sepsis develops. It is well to remember for prophylactic purposes that pus, urine, feces and the expectoration, may all hold pest bacilli, also clothing and dishes, and that they thrive during long periods in damp and moderately warm surroundings. Abundant sunlight and weak (1 to 2 per cent) solutions of bichlorid of mercury promptly destroy the offender. Therefore unfavorable surroundings invite the disease. 1. Bubonic Plague After a period of incubation of about 10 days, severe symptoms become continuous after a violent chill and high fever. The local manifestations of infection of the shin are redness, swelling, painful enlargement of the surrounding lymphatics, inflammatory reac- tion in the surrounding tissues, evidences of mixed infection, suppuration and free discharge of pus. Infection to surrounding lymphatics is prompt with furunculosis, char- acteristic carbuncles with central necrosis, and often extensive gangrene. The more favorable cases suppurate, without necrosis or gangrene. The presence of a necrotic or gangrenous center is always ominous. So-called “plague spots” are of hemorrhagic nature, and are associated with other evidences of purpura. Hemorrhages from the mucous mem- branes occur (black death, including hematuria) and are among the most unfavorable of all cases. The development of sepsis is associated with bacteremia; the bacillus is found in the blood; there is diarrhea, albuminuria, high fever of remit- tent character, delirium—often wild and uncontrollable—(pestis siderans) leading to prompt death in from 70 to 80 per cent of bubonic cases. In Egypt Gottschlich found (1899 to 1902) that there was a decided difference in the character of the epidemics during the winter and summer months. He found that during the summer the disease was widespread over entire villages and almost without exception bubonic, in which the infection spread from rats, while during the winter the pneumonic type was in the ascendency. The infection was “from man to man provoked by 204 SPECIFIC INFECTIOUS DISEASES the massing of the victims in narrowed quarters.” The ravages of bubonic plague are naturally reduced as the diseased rats are exterminated by dis- ease or by man. To prevent the spread of all types of plague must of necessity include early diagnosis, prompt quarantine, destruction of infected rats and mice, care of the cadaver, proper screening and the use of all modern methods in the care of the sick and the protection of those exposed, including the immunization with the sera—now easily obtained either from the Pas- teur Institute (Roux and Dujardin-Beaumetz) or the Institute at Berne (Lustig and Markl). Unfortunately the period of immunization is short (3 to 4 weeks). Haffkin and Gaffky have done yeoman’s service in this field and both agree that the use of the sera is of enormous value in reducing the mor- tality of plague. Ilaffkin believes that the death rate among the injected is “four times less than those unprotected.” Gaffky, who represented the German Pest Commission, unreservedly recommends the use of the Ilaff- kin protective vaccination. 2. Septicemic Plague Septicemic plague runs a rapid course with marked hyperpyrexia, deep involvement of the nervous system, delirium, coma, rapidly developing heart weakness (myocardial degeneration) ; often patients are suddenly overpowered and may die within a few hours or during the first day (pes- tis siderans). When there are purpuric symptoms (with hemorrhages from mucous surfaces), death usually promptly follows. 3. Pneumonic Plague Pneumonia may lead to death without external evidences of lymphatic invasion. In many of these cases the bronchial glands show characteristic infection. Thorough search often reveals glandular swellings in distant parts of the body. The blood is infected and shows the presence of the bacillus. Pneumonic plague may he secondary to the clearly established bubonic picture, or the involvement of the lung follows a severe chill without a pro- dromal period. The evidences of grave toxemia are fever, headache, vomiting, with or without delirium. There may be either characteristic pneumonic sputum or hemoptysis. The latter with the hemorrhagic cases is always most ominous, for pul- monary edema is likely to be present. The unfavorable features which are usually present, besides the symptoms mentioned, are hurried respiration, marked dyspnea, cyanosis and often besides evidences of vasomotor paralysis, marked degeneration of the myocardium. BACTERIAL DISEASES 205 The pneumonic process may be either catarrhal (bronchopneumonic) or croupous. The prognosis of primary pneumonic plague is uniformly unfavorable, death ending the scene in from 2 to 5 days—as a rule on the third day. Secondary bronchopneumonia offers but slight encouragement for prog- nosis ; an occasional case has been saved. 4. Pestis Minor These mild, almost symptomless cases are found at the end of epidemics or during periods when there is a lull. Patients are only slightly indis- posed ; there may be some tenderness and little swelling of the lymphatics, but insignificant febrile movement and recovery is prompt. General Considerations As we have already stated, the heart muscle is the point of attack which yields and promptly ends the life of the plague victims. There are prompt degenerative changes in the myocardium and the vasomotor paralysis which always accompanies profound toxic states. Dicrotism is usually present, blood-pressure reduced, the heart action enormously accelerated. Rapid pulse (tachycardia) with characteristic toxemia, final sudden fall of the pulse to 80 to 90 often precedes death. Fall of temperature with persistence of rapid heart action is unfavor- able. Arhythmia is less frequent than the pulsus paradoxus which is often present with pneumonic plague. If an occasional pneumonic recovers, there may he (as is often found with ordinary pneumococcus infection) during a considerable period, either persistent tachycardia, or what is often found in cases which demanded long stimulation, intermission and bradycardia. The spleen is usually slightly enlarged but offers no prognostic data, neither does the tongue which is uniformly dry, brown and coated. Neph- ritis is an accompaniment of the severe cases—hence is frequent. The blood shows moderate leukocytosis, and in the majority of cases, the presence of the Bacillus pestis. The greater the blood infection the more virulent is the disease. Reduction in the number of bacilli in the blood, and their disappearance is always of favorable, significance. Jochmann, whom I have consulted liberally in the preparation of this chapter, places the average duration of plague between 6 and 8 days and the average mortality as 70 to 90 per cent. As already stated pneumonic and septicemic plague offer the most unfavorable prognoses. The most dangerous cases to their surroundings, according to Jochmann, are those of the pneumonic type, in which the sputum and microscopic droplets 206 SPECIFIC INFECTIOUS DISEASES exhaled hold the bacilli, and as they are released, spread the infection, either directly to the lung or to the tonsils, from which, through the lym- phatics, the lungs and distant organs are invaded. Complicating meningitis is uniformly fatal. The prognosis is always more unfavorable during the early days of an epidemic than later. Alcoholism, chronic metabolic faults, previously existing and depress- ing infections, all influence plague unfavorably. References Fletcher. A tragedy of the great plague of Milan in 1630.

Tetanus (Lockjaw) The Infection Tetanus is a disease caused by the tetanus bacillus (Hicolaier and Kitasato), anaerobic, Gram-positive with one swollen end holding a spore, characterized by recurring spasms, always painful, stiffness of the neck and jaw muscles, with final rigidity of the muscles of the trunk and extremities. When fully developed there is marked opisthotonos in most cases, the body may be inclined forward (emprosthotonos) or to one side (pleurosthotonos). In some cases at times during the course of the dis- ease the limbs may continue extended straight and stiff. The spore of the tetanus bacillus is resistent to external influence, which accounts for the persistence of the germ in earth and manure during unlimited periods, from which, through wounds, it enters the skin. The bacillus remains localized, and under favorable conditions sporulation follows. The toxin produced by the bacilli finds its way into the circula- tion, is promptly appropriated by the peripheral nerves, and through these is passed to the central nervous system (Meyer). The toxin acts as an excitant to the ganglionic motor cells of the cord; hence the spasms and tetanic state of the muscles, characteristic of the disease. Tetanus may be conveyed through any objects (such as slivers, utensils, fireworks) which hold the spores. Puerperal tetanus, tetanus or trismus neonatorum and tetanus rheu- maticus, are all due to the same microorganism. BACTEKIAL DISEASES 207 Tetanus is a widely spread disease over the temperate zones of the earth, but is by no means frequent. In the last consecutive 6,000 cases of internal disease we failed to find a single case of lockjaw. Sur- geons report increasing fatalities following burns and injuries from fire- crackers and fireworks, many of which are manufactured in buildings wdiere they are easily contaminated. Factors Influencing Prognosis There are a number of facts closely related to the life history of the germ which materially influence the course and prognosis of the disease. The virulence of the bacillus is naturally an important factor. The shorter the period of incubation, the more virulent is the bacillus and the less favorable the prognosis. There are cases, usually foudroyaut, in which the symptoms follow within 3 or 4 days after injury. With the less virulent bacilli the period of incubation is long, varying from 2 to 4 weeks, and in these cases the picture of the disease is likely to be benign and the prognosis is correspondingly better. This statement ought not to lead the clinician to the conclusion that tetanus is ever a dis- ease without danger. The prognosis is always unfavorable in those cases in which the entire symptom complex of the disease develops suddenly or rapidly after the ini- tial rigidity. Such cases may show the gravest conditions within a few hours, during which there have been repeated tetanic convulsions at short intervals. In the less serious cases the development of symptoms may occupy a number of days, and the convulsions are infrequent. The patient gathers strength to resist the painful convulsions during the longer intervals and in favorable cases gets a fair amount of sleep. The frequency of the spasms is in direct proportion to the gravity of the disease. In the more serious cases the spasms may recur several times during a single hour. In the milder cases an entire day may pass with hut one or two attacks. In the more serious cases spasms are provoked by the slightest touch or movement of the body and in these, death may suddenly follow during■ respiratory spasm. Persistent sleeplessness with frequently recurring spasms is always grave. Foudroyaut cases may end in from 1 to 3 days. In these, the spasms are frequent, the pain severe, the pulse rapid and small, respirations hur- ried (20 to 80), and before death there is hyperpyrexia, the temperature reaching as high as 106° to 107° F. The urine is retained and likely to be albuminous. With hyperpyrexia the patient may fall into a comatose state. 208 SPECIFIC INFECTIOUS DISEASES Retention of urine is frequent and is not of itself to be interpreted as a serious symptom. The pulse is rapid in serious, but little accelerated in mild cases. Sudden tachycardia which persists during one or more hours with frequent spasms almost always presages an early death. Cyanosis is always unfavorable. The temperature is not materially elevated and offers nothing of value for prognosis, save in those foudroyant cases already mentioned, and in some cases before death it suddenly rises to 105°-107° F. when the patient is likely to fall into coma. With hyperpyrexia there is marked myocardial insufficiency and cyanosis before the end. The wound itself offers nothing which serves to guide the clinician in offering a forecast of the disease. If at the height of the disease there is a decided increase in the fre- quency of the tetanic spasms the prognosis is bad. In favorable cases improvement includes the lengthening of the in- terval between the attacks, decrease of muscular rigidity and pain, ability to swallow without spasm, improvement of the pulse, return of the tem- perature to normal, and decided change in the facies of the patient. Before a favorable prognosis is justified in any case of tetanus all symptoms must continue favorable during several days, for relapse can- not be excluded until convalescence has been fully and permanently estab- lished. The duration of the disease is variable; death may follow only a few hours or a few days (2 to 6) or there may be from 6 to 10 weeks of un- certainty. The long drawn out cases usually recover. Convalescence is usually prompt, and it is surprising to note how rapidly, as a rule, the patient regains his health and strength without sequelae. Myocardial weakness may persist during several weeks with some cardiac dilatation. Full recovery from this sequel is the rule as well as from arhythmia, which occasionally follows the acute period. Puerperal tetanus may develop in from 3 to 15 days after confinement, is fortunately rare, but almost always leads to death. Trismus neonatorum usually develops from 4 to 10 days after birth and is almost uniformly fatal. There are cases on record which were also fatal in which the periods of incubation of both puerperal tetanus and that of the newborn were as long as 3 weeks. The mortality of tetanus is high in cases untreated by modern meth- ods. Of the cases with a short period of incubation, less than 10 days, Rose reported 96.7 per cent of deaths, against an average mortality of 80 to 90 per cent. The prognosis of tetanus is unquestionably favorably influenced by the routine use of prophylactic injections of the tetanus antitoxin after BACTERIAL DISEASES 209 injuries. Already there are sufficient evidences at hand to justify the foregoing unqualified statement. So far as the influence of tetanus anti- toxin on the course of the disease after its full development is concerned, we have few favorable results to offer. There are a number of cases recorded in medical literature in which the injections of magnesium sulphate (intraspinous) after the method of Meltzer, with the free use of the tetanus antitoxin have been followed by recovery. There are also cases in which the hypodermic use of mag- nesium sulphate has seemed to influence the spasms favorably (Meltzer). Kocher found the prognosis bad and the magnesium sulphate contra- indicated when the cerebrospinal fluid failed to flow. References Henry. Magnesium sulphate & tetanus treatment. Internal. Clinic, 17 Series, iv. Kocher. Correspondenzblatt f. Schweitzer Aerzte, Basel, Sept. 10, 1912, No. 26. Meltzer.

Anthrax (Woolsorters’ Disease, Malignant Pustule, Milzhrandj The Infection Anthrax is a disease of sheep and cattle, caused by the Bacillus anthracis, a large, Gram-positive bacillus, which spores outside the body and is conveyed to man either through the skin directly, the lungs, or the alimentary canal, occasionally through the nose and mouth. Pol- lender in 1855, and Brauell in 1857, described the bacilli now known to cause the disease after a period of incubation averaging 7 days. The most frequent source of the infection in man is through the skin from hides, wool and pelts of the infected animals; there are some who con- tend that insects through their sting may also convey the disease from infected animals to man. Anthrax may be either (1) external or (2) internal, and is classified as follows: 1. External anthrax. (a) Malignant pustule. (b) Malignant anthrax edema. 210 SPECIFIC INFECTIOUS DISEASES 2. Internal anthrax. (a) Gastro-intestinal (alimentary mycosis intestinalis) (b) Respiratory. (c) Splenic. External Anthrax (a) Malignant Pustule.—Malignant pustule is the most frequent va- riety of anthrax found in man. Its early recognition and rational surgical and serum treatment save many patients. The fact that with anthrax there is less pain than with the ordinary furuncle, leads to delay in treat- ment and to consequent serious constitutional invasion. Rapid extension of the pustule with spreading and deep central gangrene, hemorrhagic vesicles in the periphery, extensive infiltration, erysipelatous blush with marked constitutional symptoms, are evidences of malignancy and demand a guarded prognosis. Marked lymphatic extension and tenderness with glandular enlargements are not always of serious moment; their ment without increase of constitutional manifestations after radical treat- ment is always encouraging. If the pustule is neglected, the prognosis is accordingly influenced un- favorably, for before the end of the first week there are symptoms of sepsis, including fever, delirium, diarrhea, vomiting, hematemesis, foul coated tongue, anorexia, enormous prostration, wasting, enlarged spleen, and after a period of collapse in many cases with myocardial weakness and continuation of the septic symptoms for from 2 to 4 days, death ends the scene. There are foudroyant cases in which evidences of sepsis are early and the development of grave symptoms is rapid in which death may follow within 2 days after the appearance of the skin lesion. Two-thirds of skin infections recover. (b) Malignant Anthrax Edema.—This variety of external anthrax is fortunately less frequent than is the malignant pustule. It is more fre- quently found with invasion of the face, i. e., eyelids, head, hands or arm. The pustule is absent, but the edema is rapidly formed and is diffuse. Sepsis is promptly developed and is severe; heart weakness and deep invasion of the nervous system are at once alarming. The prognosis of the edematous variety of external anthrax is almost uniformly fatal. 2. Internal Anthrax The diagnosis of all types of internal anthrax is exceedingly difficult and in most cases impossible, as a rule it is made post mortem only. (a) Gastro-intestinal Anthrax (Mycosis Intestinalis).—The progno- sis is almost uniformly bad. There are. early evidences of grave infec- BACTERIAL DISEASES 211 tion with symptoms of severe gastritis, including vomiting, often hema- temesis, bloody diarrhea, prompt evidences of sepsis, including fever and weak heart, tympany and abdominal tenderness with other symptoms of peritonitis and enlargement of the spleen. In some of these cases there are evidences of cutaneous malignant purpura with bloody vesicles. Cases of alimentary anthrax rarely live beyond the third day of the disease. The mortality varies between 50 and 87 per cent. (The post mortem appear- ances are characteristic and show changes in the mucosa of the stomach and intestines, including elevations varying in number (20 to 50) with central necrobiotic patches, black sloughs and consequent ulcerations, be- sides the enlarged spleen already mentioned.) (b) Respiratory Anthrax.—There are occasional cases of respiratory anthrax which show less tendency to pulmonary edema than does the malignant type, which run a subacute course varying from 2 to 5 weeks, ending in recovery. These cases are exceptional. The majority of pulmonary invasions offer but scant hope of recovery. The mortality may he as high as 50 to 90 per cent. They begin with many of the symptoms of a severe pneumonia, promptly develop pulmonary edema, and the victim drowns in his own serum. Pleurisy is frequent. There is in the severe cases a violent initial chill with high fever, and early manifestations of cardiac toxemia. The extensive transudate into the alveoli causes distressing dyspnea, cyanosis, and evidences of carbonic acid poisoning. In these malignant cases, the sputum is promptly bloody after a short period during which it may be serous. Hemoptysis is not infre- quent within the first 24 hours, or it may precede death on the second or third day of the disease. The heart is rapid from the beginning and soon shows the strain due to toxemia and possible secondary pulmonary obstruc- tion (edema, etc.). Diarrhea, delirium and coma are always alarming symptoms. Infection of the nasal passages, larynx, treachea or larger bronchi, with or without pulmonary anthrax, adds an enormous element of danger and usually causes death. The majority of cases of the respiratory type are found among rag- pickers or woolsorters, and as all other forms of internal anthrax, are usually fatal. Death follows after 2 or 3 days of symptoms from cardiac asthenia or because of the reduced respiratory surface due to infiltration and edema. (c) Splenic Anthrax.—Cases of splenic anthrax run a fatal course without pustule or other evidences of local disturbance, but with all of the symptoms of the more virulent and malignant types of the infection, including brain symptoms due to embolic infarcts causing hemorrhages into the cerebral cortex and the usual evidences of sepsis, characteristic of all fatal cases. Encouraging reports which prove the value of the antianthrax serum 212 SPECIFIC INFECTIOUS DISEASES are multiplying and justify a more hopeful view of the outcome of those cases of anthrax which are recognized early and which are promptly injected and treated, than has been offered in the past. Pasteur’s prophylactic vaccination of cattle and sheep has reduced the mortality among these in France to one-twelfth the former number, while the production of active immunization by means of the Sobernheim serum, now largely used on the continent of Europe, seems to be more certain and lasting in its effect—all of which argues favorably for the protection of mankind against the disease and the consequent limitation of its ravages. XVIII. Glanders {Farcy, Malleus, Die Rotz) The Infection Glanders is a highly contagious disease, due to the Bacillus Mallei (Loeffler-Schiitz Bouchard, 1882), a Gram-negative germ, which after a period of incubation, varying from 3 days to as many weeks (usually from 3 to 4 days) is followed by symptoms of sepsis, suppurating and granulat- ing ulcerations, either of the nose or skin, with a tendency to spread over the body rather than to remain localized. The tissues around the ulcers are infiltrated. The ulcers are crater- shaped after a period of pustulation when the skin is involved. The disease is contracted from infected horses, mules, donkeys, rarely from other animals; the secretion of the ulcer in the nose, occasionally of the skin, holds the disease-producing bacillus. Those working in stables and on ranches are oftenest infected. The disease is either: (1) Acute glanders, or (2) Chronic glanders. 1. Acute Glanders Acute glanders rum a rapid course to a fatal termination as a rule in from 7 to 14 days. The serious nature of the infection is recognized by the weakness and wasting during the period of incubation after which the severe chill, immediate constitutional symptoms and the facies of the patient with local manifestations, promptly prove the presence of grave disease. The spleen is usually palpable and enlarged. The site of infection shows changes early; there is redness, swelling and great pain when the skin is involved with the development of vesicles, pustules and ulcers. Nasal infection is associated with early symptoms of dry catarrh, soon followed by ulceration and abundant secretion which becomes foul-smell- ing and purulent. Nodes form on the mucous membrane of the nose, are BACTERIAL DISEASES 213 often found on the conjunctiva, in the mouth, pharynx, larynx, bronchi, lungs, intestines, and after 7 to 10 days appear in the muscles, usually those of the arm (biceps) the chest and calves. In occasional and rapidly fatal cases the disease begins with symptoms of transitory facial erysipelas or marked redness of the face after which the true nature of the disease is manifested in the development of the nasal and cutaneous changes. In all cases the lymphatics in the neighborhood of the lesion are swollen and tender. There are acute and rapidly fatal cases in which the early symptoms are those of general sepsis, which latter antedate all local manifestations and obscure the diagnosis. There may be periarticular swellings with pus formation and infiltration. Far-reaching invasion of the lung is uniformly fatal. The usual changes found with general sepsis in vital organs, heart and Jcidney particularly, increasing weakness of the former, insufficiency of the latter, are prominent before death. The character of the fever varies, but as a rule, it is intermittent; the sweats are often profuse and weakening, and with a rapid small pulse, such cases die during the second or third week. The onset of delirium or other symptoms of deep involvement of the nervous system, including coma is always ominous, usually fatal. 2. Chronic Glanders This form of the disease may persist during a number of months or several years with exacerbations of all of the symptoms and multiple lesions of the acute cases already considered, including ulcerations, many abscesses, muscle nodes and lymphatic enlargements. Bollinger reports a case which lasted 11 years, while Romberg mentions cases which con- tinued with irregular fever 1 and 2 years. Recovery from chronic glanders is not exceptional and may follow in 50 per cent of cases. Bristow reported a case which he persistently treated with an autogenous vaccine in which the patient made a full recovery. Prophylactic measures which include the prompt killing of all infected animals and the thorough disinfection of stables, cleanliness and the use of antiseptics by those who are exposed, with the early injection of mal- lein (a filtrate a dead glycerin and boullion culture of the Bacillus mal- lei) offer the only methods of controlling the ravages of the disease.

Leprosy {Lepra; Miselsucht (German); Meltzei (German); la Lepre (French); la Lebbra (Italian); Spedalsklied (Norwegian); Melaascheid (Dutch) ; Elephantiasis graecorum) The Infection Leprosy is a chronic infectious disease due to the lepra bacillus of Hansen (1871) (Bacillus leprae), which has been known for ages, is mentioned in the hible, in the old literature of India, was prevalent among the Egyptians, the ancient Jews and Greeks, many centuries before the Christian era. The history of leprosy includes one of the most interest- ing and important chapters of medicine, and should be studied by the student, that he may gain an idea of the importance of the infection during all of the ages, the sufferings of its victims, who were always feared, and usually banished to exile, too often neglected. Even Moses banished the afflicted from the camps of the Children of Israel. Since time immemorial the civilized and semi-civilized nations have all treated the leper with the same fear and have left him to his fate. It is a strange fact that in and in Portugal, leprosy has continued endemic to the present day, also in the West India Islands. With the introduction of syphilis in the fourteenth century leprosy seemed to recede. The disease was introduced into America by the African negro slaves. Indians seem to resist the infection while the European, the mixed races and negroes are most susceptible (Krause). Leprosy is not hereditary; it may be transmitted just as is tuberculosis. The new born babe has not been found infected, and the youngest leper children are not older than from 3 to 5 years. All persons above the third year may be attacked. Leprosy has a period of incubation which may extend over many years (3 to 32). The disease is rarely conveyed to the attending physician or to the nurses. For over 25 years we have been interested in the fate of a number of noble Sisters of Charity who went from St. Joseph’s Hospital, with which we have been connected, to Molokai in the Sandwich Islands; they have been in close contact with the lepers of the colony and all have continued free from infection. The disease is characterized by symptoms of three types: 1. Tubercular type. 2. The anesthetic type. 3. Mixed type. 1. The Tubercular Type This type includes skin changes in which, during varying periods, there are hyperesthetic and reddened macules usually on the face and BACTERIAL DISEASES 215 hands, later on the legs (elpra maculosa) in which nodules (tubercles) finally develop w7hich undergo retrograde change (necrobiosis), ulcerate, often involving the underlying tissues including the tendons, the bones and the adjacent soft parts. In some cases there are but few or no tuber- cles or nodules; the skin continues anesthetic, becomes pigmented, and shows other trophic changes; the spots of original erythema may bleach, becoming strikingly white (lepra alba). Sensory changes may develop very slowly; when once present they persist. Fever may precede the development of pigmentation or other visible trophic changes (lepra alba). The hair is usually diseased or lost; mucous membranes may show marked changes (including the conjunctiva and nasal mucosa) ; ulcerative keratitis and deep ocular changes may lead to far-reaching destruction and blindness. Many lepers of the tubercular type die of laryngeal invasion or pneu- monia. The prognosis is absolutely bad. The tubercular type of leprosy is more contagious than is the anesthetic. The nasal secretion according to Sticker holds the infecting bacillus, and he believes that the disease is spread from this course. Meier has proved that 70 per cent of tubercu- lous lepers offer a positive Wassermann reaction. Sexual intercourse is not an important factor in transmitting the disease; its influence is greater when the victims live under unsanitary conditions. Munch found that with marriage of short duration of a leper and non-leper, the disease was transmitted in 2.5 per cent of cases; while with those wTho lived together in matrimony during long periods of time the statistics showed 11 per cent of transmissions. Early invasion of the mucous membranes particularly the larynx is unfavorable so far as the duration of the disease is concerned. 2. The Anesthetic Type The anesthetic type of leprosy is characterized by anesthesias and hyperesthesias. There are severe pains in the extremities (usually the legs) with hyperesthetic areas or there may be anesthesias. In some cases there are both anesthesic and hyperesthetic patches. As the disease develops, the nodules may easily be felt along the nerve trunks, and the trophic changes are marked. These include the formation of blebs with final ulceration which is deep and extensive, changes in the extremities, usually the toes and fingers, in which there are contractures, destruction of tissue and gangrene of terminal phalanges. The prognosis so far as life is concerned with anesthetic leprosy is not bad, for the patients may live and continue useful during many years; as a rule they die of inter current disease. The deformities due to loss of tissue and contractures prove a serious handicap, as do the anesthesias and paresthesias. 216 SPECIFIC INFECTIOUS DISEASES 3. The Mixed Type The possibility of the mixing of the two types in the same patient must be remembered. The tubercular type is very likely to develop periph- eral anesthesia and the patient dies with “mixed leprosy.” The anesthetic type is not likely to develop the characteristic “tubers” of type 1. Leprosy predisposes to tuberculosis; about 30 per cent of lepers were found tuberculous at the Trinidad Asylum. Nephritis is a frequent and serious complication; Abraham’s statistics showed that 32 per cent of 109 lepers autopsied had kidney disease. “There was no specific leprous invasion” of the kidney. Death may follow 1 or 2 years of infection in rare cases; there are on the other hand cases in which the disease has appeared to be arrested— even cured—while a period of 40 years has been recorded in some in- stances. Abrahams reports 18 years as the average duration of cases in Trinidad, 6| years for the nodular; 10 years for the anesthetic types, and 9f years for the “mixed” cases. In young subjects the disease progresses more rapidly than during the active years of life, this is true of the anesthetic type particularly. Invasion of the internal organs always shortens life. With far-reaching infiltration of the skin the progress is slower than with multiple tubercle deposit. The number of cases is being rapidly reduced by the segregation of lepers and their proper hygienic care. Relapse The majority of cases which have been watched in which recovery was suspected, relapse after long or short periods, finally running an exceed- ingly chronic course. It may he safely assumed that “once a leper, always a leper.” References Abraham. Allbutt & Rolleston, 2. ed., ii, 665. Krause. Mohr & Staehelin, Handbuch der Medizin. i, 876. Meier. Lepra. Biblioth.

Tuberculosis Tuberculosis includes all diseases caused by the Bacillus tuberculosis of Robert Koch (1882), which latter causes the formation of nodular de- posits (tubercle), or diffuse infiltrating masses, showing tendency to be- BACTERIAL DISEASES 217 come caseated, causing ulceration and breakdown of included tissue, with an effort on the part of nature to heal by the formation of new connective tissue, calcification, the enclosure of deposits and the walling off of cavities. The disease is infectious, contagious, preventable and curable. History There have been epoch-producing periods and events in the history of tuberculosis which have cleared the horizon, proved the cause and pathol- ogy of all tubercular processes, extended our knowledge, made diagnosis positive, established rational methods of treatment and prophylaxis, and have further entirely changed the prognosis of all forms of the disease. Medical history includes references to tuberculosis, centuries before the Christian Era. Hippocrates understood and described the manifesta- tions of the disease 400 years before Christ; Celsus, Aretaeus, and Galen were also familiar with the disease but added little to the work of Hip- pocrates. The first advance was made when Sylvius (seventeenth century) demonstrated the association of nodular deposits with consumption. He considered these enlarged lymphatic glands. The next advance was made when Morton, a contemporary of Sydenham, in 1689 contributed a work in which he gave a classic description of the clinical history of the disease. Morgagni and Baillie followed, denying the identity of the tubercle nodules and demonstrated that they are not enlarged lymphatic glands. Their gross anatomic structure was recognized. The two most important advances of the early nineteenth century were: (1) the recognition by Bayle of the anatomic structure of the miliary tubercle with the recogni- tion of its general distribution, and its importance in causing constitu- tional disturbances, and (2) the establishing by Laennec (himself a victim of the disease) in 1819 of the most valuable of all knowledge con- nected with tuberculosis, save the discovery of its cause, the unity of all tuberculous lesions. At first his dictum was controverted; even Virchow remained unconvinced and differentiated cheesy pneumonia and other tuberculous processes. Fortunately Virchow lived long enough to change his views and subscribed willingly to the established conclusions of the French clinician. Valsalva and Morgagni understood the contagious nature of tubercu- losis. It remained for Villemin by experiment in 1865 to offer the next great advance in the history of tuberculosis and to lay the foundation of all advances which have followed since his day in connection with this disease. He proved the communicability and the infectious nature of all forms of tuberculosis, pointing the way to the search for its cause. Villemin’s work has failed to receive the attention and the praise from the profession which its enormous importance deserves. His name will live in history so long 218 SPECIFIC INFECTIOUS DISEASES as our science and art sliall endure. Cohnheim, the leading pathologist of Germany, ridiculed the conclusions of Villemin; but he too lived to acknowledge his error and subscribed fully to knowledge which is now universally understood by the professional and lay world. In 1882 Robert Koch, a quiet, modest, almost unknown observer, working patiently away from the large medical centers, gave the world the results of his investigations and demonstrated the Bacillus tuberculosis as the real cause of all forms of tuberculosis, wherever located. Then followed in rapid succession the appreciation of the needs of the tuberculous sick by such men as Brehmer in Germany, and our own Trudeau, the underlying basis of their success including the full apprecia- tion of the life history of the infecting agent, the resistance which the patient offered when placed in a favorable environment reinforced by the strength which resulted from pure air, a flood of sunlight on the body and on the germ as well, with the pabulum so much needed to lift the resisting power of the patient to par or above. Alonzo Clark, my revered teacher in 1877 and before, repeatedly insisted that “tuberculosis can never advance in normal tissue or when the patient’s health is at par,” to which we add to-day: the tubercle bacillus does not readily proliferate or find a suitable habitat in normal tissue. The germ lies ready to attach, and the disease progresses when vitality is lowered and tissues are changed from the normal. The final factors which have influenced the prognosis of tuberculosis have been the education of the people, and the growth of professional hnowledge which makes the early recognition of the disease possible. The tuberculous subject to-day enters upon the early treatment of his condition fully instructed, with hope and the belief that by natural methods he will either be cured or his disease will become latent. The factors previously mentioned have influenced prognosis favorably in all civilized countries during the past 30 years. The data collected by statisticians, particularly those of Hoffman, deserve recognition and wide publication. In the United States, statistical evidence proves that the mortality from pulmonary tuberculosis has actually and relatively diminished; “that on the basis of rates for the registration area, the saving of lives due to the campaign against this disease during the decade ending 1910 alone, has amounted to nearly 200,000.” The death rate during the past decade has been reduced from 174.5 per hundred thousand of population to 139.7. Hoffman s study of the combined mortality from tuberculosis of the cities of Hew York, Philadelphia and Boston for 100 years, commencing with 1812, shows a persistent reduction of the death rate from 418.6 per hun- dred thousand population in the first decade of this period to 213.9 in the last decade. This tabulation of Hoffman’s is the first ever made for any group of large cities and establishes the fact that the greatest reduction commenced with the discovery of the tubercle bacillus in 1882 and the BACTERIAL DISEASES 219 education of tlie masses. The death rate in 1881 was 389.1, in 1912 it had declined to 180.1 per 100,000. A study of 50 large American cities for the 40 year period beginning 1871 shows a fall from 335 per hundred thousand in 1881 to 166 in 1911. In the northern and western cities the decline was from 325 to 160 per hundred thousand, or 50.8 per cent. Among the whites of the southern cities the fall was from 301 to 150 or 50.2 per cent; the colored population showed a reduction from 668 to 423 or 36.7 per cent. Massachusetts, Rhode Island and Connecticut show a decrease from 276 per 100,000 population in 1881 to 146 in 1911—47.1 per cent. The reduction in the death rate for women is greater than the decrease for men. The statistics as collected by Hoffman—a work for which the profes- sion owes this layman an everlasting debt of gratitude—prove that the reduction “in the tuberculosis death rate in the United States during the last 40 years has not been less, but in many cases more than in other civil- ized countries throughout the world.” In England the drop in the death rate during the past 40 years is almost 50 per cent. In London from 1901 to 1910 (Osier) the death rate from con- sumption has dropped 33 per cent; all other forms of tuberculosis have been favorably influenced. In Germany there has been a like and encouraging reduction. For the clinician, in the light of our present knowledge, it is safest to recognize two pathogenic types of bacilli as the cause of human tubercu- losis: I. Typus humanus (Koch). II. Typus bovinus (Theobald Smith). The overwhelming number of cases are due to the typus humanus of Koch. A bitter war has been waged in connection with the part played by the bovine tubercle bacillus in causing human tuberculosis, von Behring is a strong advocate of the theory of bovine tuberculosis, introduced by milk (enterogenic infection) as the main cause of pulmonary tuberculosis, assuming that the bacilli remain latent in the lymphatics during many years; to which Calmette vigorously subscribes. Robert Koch in London at the Congress for Tuberculosis (1902), and often after that memorable occasion, held opposite views. Koch did not believe that the bovine bacillus was pathogenic for man, and advanced strong arguments to prove his contentions. The conclusions of Kossel are as follows: 1. Pulmonary tuberculosis with few exceptions depends upon infec- tion with the typus humanus. 220 SPECIFIC INFECTIOUS DISEASES 2. Tuberculosis is conveyed from man to man by means of the Koch bacillus. 3. Bovine transmissions of tuberculosis to the human subject through milk or meat (typus bovinus) is rare and of minor importance. It will be noted that Kossel, an ardent disciple of Koch, does not com- mit himself against the possibility of bovine infection, but concludes that “to control tuberculosis, contagion from man to man must be prevented.” Orth contends that 10 per cent of all forms of tuberculosis of early life are of the bovine type and cites Kossel’s own statistics to prove the truth of his contentions. These show the bovine type in 4.3 per cent of bone tuberculosis, 10.1 per cent of tuberculous meningitis, 23.8 per cent of general tuberculosis, 40 per cent of tuberculosis of the neck glands, and 49 per cent of all forms of abdominal tuberculosis. Orth’s conclusion for our purpose is significant: “tuberculosis cannot be effaced so long as bovine tubercle bacilli are conveyed from infected animals to man.” Heredity as a Factor in Prognosis Does heredity, by the transmission of tuberculosis from parent direct to the offspring, influence prognosis ? This question has been vigorously debated during the centuries. We are agreed that both in man and in the calf congenital tubercle is so rare as to be a curiosity. The child is not born with tuberculosis, the disease is acquired, Bande- lier and Roepke contend that medical literature includes but 120 cases of congenital tubercle, of which only 20 bear close scrutiny. Tubercu- losis during the first months of life is exceedingly rare. I have repeatedly used the von Pirquet test in babes, the offspring of tuberculous mothers or fathers, with negative result until the time of infection. One of the great advantages of the von Pirquet test for diag- nosis and prognosis is the fact that the time of infection can be established by it. If in a child, the offspring of a tuberculous parent there are no symptoms and the test is negative, later symptoms develop and another test is positive, it may be concluded that tuberculosis wherever located has not existed long. What the offspring of the tuberculous parent inherits, is a vulnerabil- ity, a predisposition, ivhich makes the child ready to develop tuberculosis on slight cause. The susceptibility in other words is greater in the off- spring of the tuberculous than in the child coming into the world without handicap. Every clinician of experience numbers “tuberculous families” among his clients. The following quotation is clear and to the point: “Dr. Horder says that the existence of tuberculous families is one of the cardinal facts in clinical medicine, and I agree with him; but on this point I am disposed to make one or two remarks. I would oppose the too frequent assumption—not by the present writers—that the victims BACTERIAL DISEASES 221 of tuberculosis are after all weaklings whose weeding out is painful to their friends, is on the whole, good for the stamina of the race. It is true that by inheritance or by privation, a person may be so debilitated as to offer a lessened resistance to any injurious influence from without; but, on the other hand, in respect of tubercle, such a lack may mark a family from generation to generation, as a peculiarity rather than a frailty, or at worst, as a flaw which is open to one kind of stress only.” “Such a constitution is as a lock, which may be shut to every key but one. Bar the tubercle, and such a one may continue strong and beautiful” (All- butt). Brehmer found that the youngest children of tuberculous parents and their children in turn were most disposed to tuberculosis. Children of the tuberculous show a higher mortality than do those of non-tuberculous parents, the death rate decreasing as these children grow older. The death rate is greatest among these children, the nearer their birth to the time of the parents’ death. We have found under improved environment that the removal of these children from the danger of infec- tion is a most important factor, for thereby their lives can often be saved. Congenital stenosis of the pulmonary valve invites tuberculosis. It is the exception to find a child with this defect without tuberculous infection after the fifteenth year; often earlier. Alcoholics wflth inherited susceptibility are ready victims. The habitus phthisicus predisposes to pulmonary and other forms of tuberculosis. The misshapen chest, the small heart, the tendency to glandular enlargements (lymphatism) and the habitus asthenicus (Kraus, F.) including faulty growth and development, are among the factors which invite in the vulnerable, the non-resistant, and predisposed, the develop- ment of tubercular phthisis. Acquired and Inviting Factors Acquired and inviting factors are of paramount importance in the development and progress of tuberculosis. All diseases which lower vitality increase susceptibility to tuberculosis. Improper diet, bad air, insufficient ventilation, crowded cities, tenements, impurities of all kinds, inhalation of dust, poor clothing, prolonged damp- ness, sedentary occupations, pernicious habits, alcoholism, worry, want, the crowded prison and workshop, all lower resistance and invite tuber- culosis. All acute and chronic respiratory diseases which are associated with changes in the bronchial nodes or respiratory mucous membrane, unless controlled by treatment or placed in favorable general condition, offer a ready culture medium for the tubercle bacillus. A large number of children are infected from tuberculous invasion of the bronchial lymph nodes which has remained latent during months at times, following measles, whooping cough, pneumonia (lobular and lobar), acute bronchitis, scarlet fever (less often), and other infections. 222 SPECIFIC INFECTIOUS DISEASES In the adult, typhoid fever, malarial, and influenzal diseases, as well as syphilis, also prepare the individual for further infection by the tuber- cle bacillus. Usually they kindle a latent process into activity. Dia- betes and pregnancy are among the inviting conditions. When tubercu- losis follows pleurisy, the latter was in all probability of tuberculous origin also. There are diseases which seem to offer resistance to the progress of tuberculosis; these include gout, nephritis, asthma, emphysema, and mitral stenosis. The consecutive hyperemia associated with mitral stenosis is held to be antagonistic to the development of tuberculosis. The infection with tubercle bacilli of the majority of mankind at some time during life, usually before the twelfth or fifteenth year, unquestionably produces a degree of immunity and proves an important factor in prognosis later in life, von Behring believes that the favorable course of chronic tubercu- losis in the adult is due to this acquired and relative immunity. Tuberculosis is a disease of all ages. By predilection it chooses the lymph nodes, bones, and the meninges in early life. The importance of latent tuberculosis at all ages deserves serious consideration as a factor in the sudden dissemination of acute miliary disease. The prognosis of any form of tuberculosis presents serious difficulties owing to the variety of anomalies with which the disease may be associ- ated, the inherent tendencies of all tuberculous deposit, the inability to measure at any stage of the disease the resistance of the infected individ- ual and the intensity of the infection. It is not always possible to estimate the extent and location of the disease. There is scarcely an organ of the body which may not harbor one or more tuberculous deposits for years without revolt and without subjective or objective symptoms. Prognosis therefore must rest upon the clinical manifestations of the individual case and their association with such pathologic changes as are made clear by physical examination and the refinements of diagnosis. !No man can safely pierce the future of any form of the disease who has not a thorough understanding of the characteristics of the tubercle, its inherent tendencies including its easy breakdown, ulceration and caseation, the possibility of reparative and protective processes, its frequent latency as well as the enormous variations in the resistance of those infected. 1. Acute Miliary (General) Tuberculosis Acute general miliary tuberculosis, in contradistinction to acute pul- monary miliary tuberculosis, is a far-reaching general infection, secondary to an existing focus, which is spread by the bloodstream, characterized by the formation of milletseedsized tubercles in large numbers, in many organs at the same time. Acute miliary tuberculosis is always proof of initial invasion of either a blood-vessel or lymphatic (thoracic duct), from BACTERIAL DISEASES 223 which bacilli are distributed to distant organs (Weigert). Experiences with acute miliary tuberculosis prove the importance of cautious observa- tion of all children and adults who have periods of indefinite symptoms in which positive diagnosis cannot be made and those who have had other acute or chronic infections which are likely to leave foci which invite tuberculous deposit. This is true of all acute diseases of the lung and bronchi which may be associated with latent deposits in lymph nodes, from which, as the general health of the host is reduced, bacilli find their way into the blood-stream (vein, artery, or lymphatics). There is often direct dissemination through the lymphatic channels from the thoracic duct into the right heart. Neglected pleurisy may supply the infection. Otitis media, the suprarenals, the genito-urinary tract or any of its separate organs, bone, or joints serve in different infections as the primary focus. Infection through the aorta and heart wall, the pulmonary artery, the carotid, may spread miliary disease. With miliary as in all forms of tuberculosis the vulnerability and susceptibility of the carrier of a latent focus become important prognostic factors. Ribbert called attention to the conservative processes which in the resistant prevents the entrance into and the invasion of the blood. In these there is a strong tendency to pre- vent contamination by protective local hyperemia, marked dilatation of vessels, acceleration of the local circulation, etc. The depressing and weak- ening effect of pregnancy and childbirth become important factors in low- ering the resistance of the patient and spreading infection. There are three clinical forms of acute miliary tuberculosis, each of which is characterized by the presence of leading symptoms: I. The typhoid form. II. The pulmonary form. III. The meningeal form. I. Typhoid Form The typhoid form of miliary tuberculosis resembles enteric (typhoid) fever, in so many ways, that but few men of large experience will deny having made errors of diagnosis. There may he and usually is enlarged spleen, albuminuria and irregular fever, which may assume the typhoid curve! Diazo (Ehrlich) reaction is positive; heart sounds rapid; systolic murmur distinct in many cases. Unless there is complicating tuberculous meningitis, the pulse may he dicrotic and rapid. If there is meningitis, during its early stage the pulse is slow. The symptoms which are unfavorable include: rapid pulse, low blood- pressure, marked apathy, involuntary discharges of urine and feces, and albuminuria. Leukopenia and reduced hemaglobin, in some cases, and relative reduc- 224 SPECIFIC INFECTIOUS DISEASES tion of lymphocytes have characterized the graver and more acute forms of miliary infection. Leukocytosis of moderate degree is occasionally pres- ent. Hurried and irregular respiration with or without cough, Cheyne- /SHokes breathing, are all unfavorable and are soon followed by death. II. Pulmonary Form With evidences of acute infection, but without the marked and positive physical signs of acute pneumonic tuberculosis, there is a progressive loss of strength, with lung symptoms in the ascendency. These include dry cough, but little or no expectoration, at times rusty sputum, mucopurulent, rarely hemoptysis. It is difficult to make the accurate anatomic localiza- tion of lung changes, for the percussion note may not be changed and in many cases there are but few rales. In children the pulmonary form of acute miliary tuberculosis may promptly follow measles, whooping-cough, typhoid or other infections; or the bronchial nodes infected during these diseases may later, after long periods of latency, without symptoms and in apparent health, erode vessels or lymphatics and lead to general and fatal miliary tuberculosis. When any of the forms of miliary tuberculosis fol- low immediately on the acute infections the prognosis is absolutely bad, progression is rapid. The physical signs depend upon the size of the deposit, the amount of bronchitis and the associated acute and chronic changes. In some cases there are evidences of old and latent disease, there may be general infection with all of the symptoms of sepsis and no evident change in old deposits long recognized, which are the direct cause of miliary dissemination. With associated broncho-pneumonia the lung symptoms are most prom- inent. I have seen both lungs studded with miliary tuberculosis at the autopsy in cases which presented no positive physical signs during life. In such cases x-ray examinations will strengthen diagnosis and prognosis. The pulmonary form of acute miliary tuberculosis may be associated with the typhoid condition and to this may be superadded tuberculous meningitis. These cases are found both in children and adults. III. Meningeal Form (Tuberculous Meningitis, Basilar Meningitis) These cases have a well-defined prodromal stage during which the diag- nosis can he made and the prognosis given. The symptoms of this stage include irritability of the child, sudden vomiting, hydrocephalic cry, paralyses within the domain of the motor oculi, the facial or other cranial nerves, later opisthotonos, increasing apathy, at times early convulsions. The cerebral macule (dermography) is present, and as I determined from an analysis of a large number of cases, death followed in seventeen days BACTERIAL DISEASES 225 from the beginning of the continuous train of symptoms. The Kernig symptom is usually but not always present. My experience has been uni- formly unfavorable with tuberculous meningitis. My preceptor, Didama, believed that he had one recovery in his large experience. While I was writing this chapter I saw a case which Treupel presented at a post grad- uate clinic in Frankfort on the Main (Oct. 25th, 1913) of a boy in whom the spinal fluid contained tubercle bacilli, and all other elements, including ophthalmoscopic find, satisfied him, that the case was one of tuberculous meningitis, and fully recovered. The statement has been recently made (London Lancet), that one in 200 cases of tuberculous meningitis recovers. Pitfield reports 29 cases (one of his own) from medical literature which recovered. In 10, necropsies confirmed the diagnosis, in 18 tubercle bacilli were found. McCarthy in several reports of the Phipps Institute states that he fre- quently found evidences of healed tuberculosis of the nervous system in persons who ultimately died of phthisis pulmonalis. Others hold that the prognosis of tuberculous meningitis is not absolutely bad and base their conclusions upon the post mortem evidences of healed meningeal tuberculosis. The incidence of cure among the thousands of reported cases is so slight that in offering a prognosis it deserves but insignificant consid- eration. Tests Tuberculin Tests.—In all forms of positively diagnosticated acute miliary tuberculosis the tuberculin tests, preferably von Pirquet, Calmette and Moro, will in the overwhelming majority of cases give negative results. Tuberculous meningitis rarely reacts to these tests; my experiences prove them negative in over 90 per cent of all cases. The typhoid type is almost uniformly negative to the skin and ocular tests; injections of tuberculin are contraindicated. Negative tuberculin tests above mentioned, in cases positively tuberculous (acute miliary tuberculosis), argue in favor of un- favorable prognosis. The ophthalmoscope offers positive information in over 75 per cent of cases of miliary tuberculosis and should therefore be used for diagnostic and prognostic purposes, in this and in all forms of miliary disease. The study of the opsonic index is of indifferent or slight value for prognosis of any form of tuberculosis, and is unavailable for general use. (Bandelier in Roepke, 1. c.) Lumbar puncture is of positive prognostic value, for it clinches the diagnosis in doubtful cases very often, when tubercle bacilli are found in clear fluid as a rule under high pressure, with the presence of lymphocytes. It must be remembered that the latter may be present with congenital syphilis also. Sugar in the Cerebrospinal Fluid.—Connall, who has given this sub- 226 SPECIFIC INFECTIOUS DISEASES ject great consideration, has examined 122 specimens from §9 cases of tuberculous meningitis and reports his results as follows: “In tuberculous meningitis sugar was found to be present in the great majority of the cases, and at all stages of the disease; 122 specimens were examined. An active reduction on boiling of the Fehling’s solution oc- curred in 15, a partial but decided reduction in 102, and no reduction at all in only 4 instances. Complete absence of sugar was observed in only 2 cases. It was noted in the last week of illness, three times in one case and once in the other, and in each case at other times there was a slight reduction of Fehling’s solution.” Jacob concludes that “In tuberculous meningitis sugar is present, except in very rare cases shortly before death, in which stage difficulty of diagnosis rarely exists.” While the presence or absence of sugar is of some prognostic value, it is not of the same significance as in cerebrospinal meningitis. The majority of children who die of tuberculous disease between the first and fourth year fall victims to tuberculous meningitis; 40 per cent of these die during the first year of life and 60 per cent after. This high mortality is reduced with advancing years. In 70 per cent there is an hereditary predisposition. Koch (Bandelier and Roepke) reports 355 cases of tuberculous meningitis in which 130 had measles and 67 whoop- ing cough preceding the tuberculous infection. The proportion of adult tuberculous meningitis to the infantile is 1 to 7.5 (8 to 60 cases). (Pulmonary Consumption, Phthisis pulmonalis, Phthisis tuberculosa, Schwindsucht [Lungen]) 2. Pulmonary Tuberculosis All lung diseases due to the Bacillus tuberculosis are included in the group of pulmonary diseases known as consumption or phthisis pulmonalis. We will consider the prognosis of the disease basing our conclusions on the following classification: I. Acute pneumonic tuberculosis (lobar or lobular). II. Chronic pulmonary tuberculosis (ulcerative and caseating). III. Chronic fibroid phthisis (chronic tuberculous pneumonia) (tuber- cularized pneumonokoniosis). In all forms of lung tuberculosis we are dealing with complex problems and changing elements which must of necessity influence prognosis. It may be said that the extent and location of the tuberculous process, the virulence of the infecting agent, the many general factors already consid- ered, including predisposition (acquired and inherited), associated clinical manifestations which show the resisting power of the infected, the stage of the disease, the ability of the patient to take advantage of conditions which offer an obstruction to the onward march of the disease and stimu- BACTERIAL DISEASES 227 late the reparative and protective processes, with many other factors, to- gether and alone, influence the forecast decidedly. I. Acute Pneumonic Tuberculosis There are unquestionably cases of acute tuberculosis in which the deposit is limited, where there are indefinite symptoms during a short period, slight febrile movement, insufficient physical signs to make locali- zation possible, languor and anorexia which yield. Nature comes to the rescue. Calcification or fibroid change in these limited areas are re- sponsible for many healed and circumscribed lesions which are included in the post mortem findings in many who finally die of non-tuberculous disease and also for many positive tuberculin reactions. In these cases, which Sir A. E. Wright might include among the local infections, it is possible to raise the resistance of the patient sufficiently ato cause the in- fection to disappear” and present fresh infection. Wright contends that “the method of following the progress of an anti-tuberculous immuniza- tion lies in the observation of the opsonic capacities of the serum.” Pa- tients in whom the deposit is limited show a low opsonic index; when the process is active, it is occasionally high and irregular. (a) Lobular Pneumonic Tuberculosis.—Acute pneumonic tuberculo- sis in which there are physical signs of tuberculous bronchopneumonia is a virulent infection, most frequent in children, and usually associated with rapid loss of strength, cyanosis, hurried respiration and cough. There may be hemoptysis, and but few or no tubercle bacilli, depending upon the stage of the disease, evidences of constitutional disturbances and death in from two weeks to several months. It is surprising to note how long some of these patients tolerate the high temperature and the rapid pulse. A chronic stage follows, and months of fever, with extreme wasting, dry un- satisfactory cough, with night sweats, may precede death. In some there is laryngeal invasion finally, which makes the end painful. A reversal of the usual type of hectic fever in acute tuberculosis, high morning tempera- ture and nocturnal fall, is indicative of rapid failure and early death. The acute galloping consumption which may be either lobar or lobular (often of the mixed type, with far-reaching miliary deposit, infiltrating tubercle and in some cases coalescence of the smaller miliary deposits) offers an unfavorable prognosis and is likely to be of short duration. It is also frequent in children following respiratory infections, measles, whoop- ing cough or a long period of latency, in which the bronchial nodes were primarily infected. Hemoptysis is occasionally the first symptom of the disease; acute symptoms of pneumonia may follow and progression may be rapid. With this history it may be safely concluded that there existed for sometime, "without symptoms, a latent or partially healed but limited focus which was “opened” and the spread of the disease followed. A large num- 228 SPECIFIC INFECTIOUS DISEASES ber of these acute cases are hurried to the end by the intolerance of the stomach and intestines. Tuberculous dyspepsia makes impossible the nourishing of some of these cases which become sub-acute, emaciation is rapid, heart insufficiency prompt, fever high—all conditions which invite early death. The duration of the galloping cases (acute pulmonary miliary tubercu- losis) is between 12 to 15 days and two to three months, averaging about seven weeks. (b) Lobar or Pneumonic.—In these cases there may suddenly de- velop all of the symptoms of an acute pneumonia (lobar) ; unless there are evidences of previously existing tubercular foci, the true pathologic conditions may not be suspected. There may be, as I found in one case Avhich I reported (Eisner) a sudden chill, high fever and suspicion of an apex pneumonia. There were pneumococci in abundance in the rusty sputum, the time for crisis passed without a change of symptoms, the hope for lysis was abandoned after ten days of unchanging conditions. The sputum continued free, there were evidences, after the twelfth day, of mixed infection, tubercle bacilli and the Fraenkel cocci were abundant. Close questioning proved that several years before his present illness the patient had an ischio-rectal abscess and this was the source of infection. Death resulted several months after the initial pneumonic tuberculosis, with cavity formation and other evidences of general tuberculous in- fection. There is in most of these cases an old focus which has been lighted into activity; infiltrating tubercle results; large areas are in- cluded or one lobe only is involved. With this there may also be miliary deposit. In the article which I mention above (Eisner), reference is made to pneumonic tuberculosis following aspiration of blood from germ laden cavities, after hemopytsis, as originally suggested by Baumler, to distant parts of the lung. Either pneumonic or bronchopneumonic tuber- culosis may be thus spread, and an acute process developed in the midst of chronic phthisis. It is possible for pneumonic herds to be produced solely by tubercle bacilli, without mixed infection. It occasionally happens that these types of acute pneumonic phthisis heal or fall into long periods of latency. One must not conclude that the prognosis is absolutely bad. A recent experience (1911) has been encouraging. A priest, age 45, de- veloped all of the classic symptoms of pneumonic tuberculosis (lobar) with positive bacteriologic find, with irregular fever and progressive emaciation and rapid pulse. To all who saw him the case seemed hopeless. In this condition he was transferred to St. Gabriel Sanitorium in the Adirondacks and there made, so far as we can judge from present indications and physi- cal examination, a full recovery with a gain in weight of over fifty pounds. What the future has in store for such patients we are not able to tell, but with the experience of the past already forewarned, early attention to symptoms, if any recur, may lead to satisfactory results. BACTEKIAL DISEASES 229 In all cases of pneumonic tuberculosis a guarded prognosis must be given, the fiery and acute cases will most of them fall victims to the vir- ulent toxemia, a number may live for a long time and ultimately die of chronic or subacute phthisis, others will enjoy long periods of latency, while the happier outcome of cure is a possibility and should encourage the therapeutist to take advantage of modern methods even in desperate cases. My clerical friend has remained without symptoms to the present time, the picture of health. II. Chronic Pulmonary Tuberculosis (Ulcerative and Caseous) The chronic type of pulmonary consumption is the most frequent of all lung invasions. With this, as in all diseases, as I am continually endeavor- ing to impress upon my readers, prognosis is nothing more than the con- clusions which we reach from thorough detailed and refined diagnosis. A large number of these cases are curable, many become latent; the vital fact which interests us in considering their future is that they can only be saved by early diagnosis and prompt treatment. Put in the resistance, bring the condition of the patient to par or above, and the disease, if in its incipiency, will be stayed and cured in over 80 per cent of all cases, while 20 per cent of all forms of the disease are saved. To wait for defi- nite physical signs before making the diagnosis darkens prognosis, for the patient’s chances are reduced thereby. To anticipate the final development in cases which are strongly suggestive, adds to the patient’s chances. Posi- tive physical signs are never early evidences of lung invasion; they mean that the case is advanced. Symptoms and their Prognostic Value The prognostic significance of symptoms may he summarized as fol- lows : Cough.—Cough, which is not promptly controlled by the usual methods of treatment, particularly if dry and hacking, which during the early morning hours may he followed by the expectoration of only a small pellet of sputum, which on examination gives negative results, which may or may not be accompanied by slight rise of temperature, usually some lassi- tude, is always strongly suspicious of tuberculosis. Cough with increas- ing muco-purulent expectoration is evidence of advanced disease and as a rule tubercle bacilli are present. In all cases of cough having no other symptoms to make diagnosis posi- tive, the sooner such cough is considered to he due to tuberculous deposits, the more the prognosis is improved. To wait for the appearance of tuber- cle bacilli reduces the chances of the patient. Some of these patients at 230 SPECIFIC INFECTIOUS DISEASES first cough only once or twice during the early morning hours; the cough is due to the irritation of a focus still “closed.” Each day of cough with changing sputum, increasing evidences of bronchial irritation, robs the patient of resistance and lowers his chances of recovery. Cough may continue during weeks with no sputum, even in rapidly advancing cases in which miliary deposit predominates, but in these cases there are usually other evidences—fever, emaciation and accele- rated pulse—which are strongly suggestive. These cases offer a less favor- able prognosis than do those in which, from the beginning, there are none of the symptoms of miliary deposit, though these are by no means hope- less. Cough with nummular expectoration is always evidence of advanced disease. Tubercle bacilli will be found in such expectoration without long search. Cough with increasing infiltrating deposit of tubercle may in some cases be slight, as a rule it is troublesome. Large areas of lung tissue may be infiltrated without cough. This is not a frequent anomaly but it does present; failure to recognize the true pathologic condition, postpones diag- nosis and materially influences the outcome. With cavity formation there is usually abundant purulent and num- mular sputum, likely to be periodical, most abundant in the morning. Such sputum and cough are unfavorable. Besides tubercle bacilli, there are evidences of mixed infection. If the sputum shows besides, benign saprophytes, other bacteria wrhich are pathologic, the prognosis is accord- ingly influenced. The presence of the tubercle bacillus in the sputum is proof positive of a disorganizing process; there has been breaking down of tissue, the disease has become “open” and is beyond the incipient stage. The prognosis is therefore less favorable, for in those cases (barring acute miliary tuberculosis) which are “closed,” where there are no physical signs of disorganization or tubercle bacilli in the sputum, recovery follows ra- tional treatment in between 85 and 90 per cent of cases; the time required for a cure is materially shorter than in the more advanced cases. Large numbers of bacilli are unfavorable when found in single fields. The beaded appearance of bacilli has been variously interpreted by clinicians. Many hold the beading to be favorable. My experience does not j ustify that con- clusion, as I have found this oftenest with acute or rapidly advancing disease. This may ultimately prove to have been mere accident. Elastic fibers are evidences of disorganization. Shortness of Breath.—Shortness of breath wTith uncontrolled cough, few or no physical signs, no evidences of existing lesion in any organ ac- counting for the symptom, should be interpreted as due to tuberculosis. If there is no emaciation, a good family history, but little or no fever, fair circulatory condition, such cases offer a fair prognosis if treated early. Shortness of breath is not always evidence of the extent of the tuberculous process. With existing anemia, weak heart muscle, particularly in young BACTERIAL DISEASES 231 girls, or in some cases of mixed tuberculosis (i. e., miliary and infiltrat- ing), shortness of breath on slight exertion may be out of proportion to the extent of the disease. Shortness of breath with increasing loss of weight, rapid pulse and persistent elevation of temperature is unfavorable. Bronchial Hemorrhage.—The occasional admixture of a “streak of blood” should always lead to the suspicion of possible ulceration, erosion of a capillary, or disorganization of limited extent. The “streak” may be the fore-runner of a large or small hemoptysis. It may in some cases mean nothing at all. Hemoptysis, large or small, is always proof of an open focus, hence an active process. It is by no means always followed by an increase of symp- toms or progression of the disease. In many cases it is the first evidence of existing tuberculosis, has been the signal which the clinician and patient heeded which proved fortunate, for it may lead to full recovery. Even cases with positive evidences Of deposit in one or both apices, in which hemorrhage was the first expression of existing disease, have been cured or halted by timely intervention. There is no stage of tuberculosis in which hemoptysis may not occur. Death, the direct result of hemoptysis, is exceptional. The erosion of a large vessel, usually an artery in the advanced stage of the disease, has occasionally caused sudden death. Hemorrhage may in some cases lead to anemia by recurring at short intervals or because of its profusion. The immediate effect of hemoptysis is to frighten and depress; unless the loss of blood is considerable, reassurance promptly suffices to return the patient to his previous condition. Large hemorrhages repeated at short intervals, usually in the advanced stage of the disease, naturally rob the patient of resistance, weaken the heart and, if aspiration bronchopneu- monia of mixed type or tuberculous pneumonia results in distant parts of the lung, the condition may become serious and threatening. In occasional cases there is a depressing fever following hemoptysis which may continue for several days. There are cases in which for some reason the tuberculous process ad- vances rapidly after hemorrhage and disorganization promptly follows, causing cavity formation with high fever, rapid pulse, mixed infection and death in a few months. If the changes are limited to the dependent por- tions of the lung, we assume, as already suggested, that infection was spread by aspiration. It is safe to conclude that hemoptysis not otherwise explained is of tuberculous origin, that it does not lead to tuberculosis, but is evidence of an existing focus. Franz Strieker’s statistics prove 86 per cent of hemop- tvses tuberculous where the bleeding came on without known cause. Fever.—Fever is a symptom of enormous prognostic values. Rise of temperature which is not modified or controlled by rest and suitable sur- SPECIFIC INFECTIOUS DISEASES 232 roundings argues in favor of overpowering toxemia and insufficient resist- ance, and is always unfavorable. Slight evening rise of temperature in incipient cases deserves prompt consideration, whether associated with positive physical signs or not. Its disregard as a symptom of early tuberculosis, leading to procrastination, is always against the interest of the patient. The effect of short but repeated febrile attacks without positive symp- toms, usually diagnosticated as influenza or malaria, often burden the his- tory of the tuberculous subject when he presents with continuous and posi- tive symptoms. Latham adds to these the history in many cases of “feeling tired,” “not really fit,” without having consulted the doctor. These short periods of fever of doubtful significance originally prove to be of tuberculous origin and most of these subjects present with reduced resistance and positive physical signs of advanced disease. When such cases develop continuous fever, sweating, with accelerated pulse, the prognosis is accordingly influenced. The temperature curve is an expression of the behavior of the tubercu- lous process; it must always be thoroughly considered in offering a forecast in the individual case. If fever persists the process is not under control or there is some wearing complication. Early morning rise of temperatures is always ominous; if in cases where it is present there is gradual increase during the day, with accele- rated pulse, unless controllable, it is also of serious import; such cases fail rapidly. Intermittent fever, usually a decided chill, or chilly sensation during the afternoon followed by fever and later night sweat, is evidence of mixed infection, pyogenic as a rule, and does not complicate incipient chronic tuberculosis. It may in some cases prove expressive of associated miliary and spreading infection. Night sweats, unless due to some lion- tuberculous complication, unfavorably influence prognosis. There are cases of chronic tuberculosis which yield after the appearance of night sweats, an experience which justifies persistence in the treatment of chronic phthisis. Frequent daily measurements are absolutely necessary in all cases of chronic tuberculosis, that valuable deductions as to the true condition of the patient may be obtained. Hectic fever wears the patient, weakens and depresses, and is always evidence of failing resistance; the reparative powers have been exhausted. Anorexia during prolonged periods with slight fever and loss of weight is unfavorable. In these cases, with intolerant stomach, powerful and help- ful factors are withdrawn and the patient’s chances reduced. Diarrhea.—Early or late diarrhea is unfavorable. When early, if controllable, it is not significant of intestinal invasion; if not controllable, it remains a weakening factor. Late colliquative diarrhea depletes and hastens the end. The presence of tubercle bacilli in the stool of tubercu- BACTERIAL DISEASES 233 lous subjects is not positive proof of intestinal tuberculosis. Sputum is easily swallowed or bacilli may be washed into the stomach with food and drink. With 'persistent diarrhea, tubercle bacilli and characteristic stool, ulcerative tuberculous enteritis may be diagnosticated and offers an un- favorable prognosis. Pain.—Pain is usually an expression of plewritis sicca; if more seri- ous forms of pleurisy (effusion, chronic pleurisy, empyema, hydro and pyothorax pneumothorax) are not among the complications, it is of no great significance and is transitory. The misshapen or retracted thorax, with a previous history of pleurisy or pneumonia or suspected latent tuberculosis, with adhesions or retrac- tions due to the formation of fibrous tissue formed in the process of healing and positive evidences of fresh infection or exacerbation of existing dis- ease, require consideration and deserve to be weighed in offering prognoses. Limited expansion of the thorax in cases not too far advanced may be ma- terially increased by pulmonary gymnastics in a favorable climate, thus adding to the patient’s chances. The Heart.—The small heart of the tuberculous subject has been previously mentioned. Abnormal irritability of the heart, erratic behavior under stress, is not uncommon even in favorable cases. Hearts remaining rapid under rest and favorable conditions, with or without fever, suggest advance of the process. If there is fever with rapid heart which is not controllable, at the same time gradual loss of weight, the disease is not under stress, is not uncommon even in favorable cases. Hearts remaining is unfavorable. Blood pressure study proves chronic tuberculosis to be a hypotensine disease (80-90 mm. Hg.). Sudden or gradual fall of blood-pressure, with or without evidences of advancing disease in physical signs, needs to be watched and is not encouraging. Emaciation; Weight.—Chronic tuberculous subjects, when brought under favorable conditions, if they are doing well, should show a gain in weight. In no subject who is losing weight has the disease been brought under control. Weekly or semi-weekly weighing offers valuable indica- tions for prognosis. Pye-Smith says: “To put the matter briefly, I would say that, beside family history, the less important facts for prognosis in phthisis are those which concern the lungs, and the more important those which concern the whole body. While a patient puts on flesh and is free from feyer, he is doing well, whatever takes place in his chest; while he is losing weight, and suffers from anorexia, sweating, diarrhea and hectic, he is going down hill, however little sign of disease auscultation of his chest may show.” Muscular weakness, atrophy, exalted superficial reflexes are likely to indicate advancing diseases, though by no means dependable prognostic factors. 234 SPECIFIC INFECTIOUS DISEASES Hoarseness, persisting, means either paralysis of the vocal cords or invasion of the larynx, usually ulceration of the anterior surface of the posterior laryngeal wall. Tuberculous laryngitis as a complication of chronic phthisis is always of the gravest import, decreases the patient’s chances of recovery and leads to weeks of suffering which is uncontrollable, and usually a painful death. No other condition is more likely to impress the physician with the limitations of his art. The subject of Tuberculous Laryngitis will be given special consid- eration. The Urinary Organs.—Albuminuria is not, when transitory, of seri- ous moment. In the later stages of the disease, with casts, and occasion- ally hematuria it may be an expression of either amyloid degeneration or tuberculous nephritis, when it is a symptom of serious and widespread dis- turbances. The addition of general dropsy is evidence of the terminal stage of the disease. Blood-pressure with degenerative changes in the kidney is low in pro- portion to the weakness of the heart muscle and the associated amyloid changes in the arterial walls. (Renal tuberculosis will receive separate consideration.) The Diazo-reaction (Ehrlich) is of positive prognostic value. Often present in chronic tuberculosis, if found early, it is likely to disappear as the process is brought under control and the patient improves. Persistence of the reaction after once found in severe cases (not all cases react) is with but rare exception an indication of an uncontrollable and progressive tuberculosis. There is a rheumatoid form of tuberculosis associated with chronic lung invasion, fully described in an exhaustive monograph by Poncet and Leriche which is obstinate, usually becomes chronic, and adds to the suffer- ings of the patient besides lowering vitality. Liver and Spleen.—Invasion of the liver and spleen, tuberculous de- posits of amyloid degenerations do not argue favorably for the future of the tuberculous patient. These are usually terminal complications and are not limited to the organs mentioned, but are likely to involve bone and, as already mentioned, the kidney. The usual changes in blood-vessels, characteristic of amyloid disease, with other factors lead to anemia, drop- sies and diarrhea. The Digestive Organs.—The influence of purulent discharges on the prognosis of chronic tuberculosis has been a source of controversy and dis- agreement in the past. Many of the older writers believed that the dis- charge from an ischiorectal abscess, usually a tuberculous process, had a wholesome and a restraining effect on pulmonary tuberculosis. That chronic phthisis may be complicated with chronic ischiorectal infection during many years without evident influence is true. The safest conclu- sion for us, in the light of modern knowledge, is that any tuberculous focus BACTERIAL DISEASES 235 within reach should be promptly removed; the patients’ chances are not prejudiced thereby, but rather improved. Tuberculous peritonitis complicating phthisis pulmonalis is always se- rious, but with abundant ascites is not always fatal. I number such cases among my tuberculous patients who made satisfactory progress ip whom abdominal section led to cure of the peritonitis and the lung process was either uninfluenced or in an encouraging number became latent. The Nervous System.—The nervous system, barring tuberculous men- ingitis, considered in connection with acute miliary tuberculosis, and occa- sional cerebrospinal meningitis, offers but few indications which mate- rially influence prognosis. I have met a number of peripheral neuritides, neuralgias, some suddenly arising hyperthyroideas, paresthesias, anes- thesias and finally mental disturbances, insanities, including melancholias. With the dissemination of knowledge concerning tuberculosis, the natural hopeful tendency of the consumptive has been encouraged and there is no longer in the incipient stage the depression which formerly fol- lowed immediately after the diagnosis became known; on the other hand, most patients to-day begin to make arrangements which they fully expect will lead to a happy termination. There is a wholesome autosuggestion which, if encouraged by every possible means (environment, etc.) proves an important factor in leading the patient toward recovery. The Blood.—Chlorosis and anemia invite tuberculosis. Increasing chlorosis and anemia are indicative of extension of disease or some asso- ciated depressing factor which is retarding the progress of the patient. Anemia with edema or other dropsies is always unfavorable. The blood condition may be considered favorable when the number of red corpuscles is not materially reduced, leukocytes unchanged and hemo- globin but slightly diminished. This is the blood condition which is found in the incipient stage of the disease. Grawitz, as the result of his observations found, with advance to the second stage, without fever, eryth- rocytes unchanged, slight increase of leukocytes with hemoglobin, as in the first stage. In the third stage, with fever, less favorable, there is a marked reduction of red corpuscles, decided increase of leukocytes with marked reduction of hemoglobin. The blood platelets are materially increased in number in tuberculosis. The rapid rise of the leukocytic count is always unfavorable, for it is indicative of advancing disease with mixed infection, such as is found in the terminal stages of the disease. In women, early chlorosis must be expected in many cases. A rise of color index is favorable. Increase of eosinophilia in the blood and sputum has been found by many to be coincident with improvement and their absence or decrease marked, when there are exacerbations or the disease progresses. 236 SPECIFIC INFECTIOUS DISEASES Arenth believes that the simple counting of white blood corpuscles is of no value for diagnostic or prognostic purposes and has made exhaustive studies of the blood picture, more particularly the differential count of the polymorphonuclear neutrophils with regard to the number of their nuclei. Six classes are recognized according to the number of contained nuclei. With infectious disease Arenth found, in tuberculosis particularly, that the number of nuclei in the cells is decidedly reduced in unfavorable cases; in those without resistance there is a preponderance of cells with one or two nuclei only. In the favorable cases, the percentage of leukocytes hold- ing three and more nuclei is increased. In bad cases Arenth therefore contends, and clinical experiences strengthen his contentions, that “there is a shifting of the blood picture on the left, i. e., one or two nuclei.” (“ Verschiebung nach Links.”) The blood picture, therefore, shows, “as against the normal (25 per cent mononuclear, 75 per cent polynuclear leukocytes) an enormous disproportion in unfavorable cases; increase of mononuclears and decrease of polymorphonuclear cells.” Ringer and Minor have given some interesting data including their experiences with the “Arenth leucocytic picture in pulmonary tuberculosis and its prognostic value.” The first mentioned made 729 counts in 475 patients. They divided their cases according to the extent of the lung invasion into four groups. 1 Good. 2 Medium. 3 Bad. 4 Very bad. Going over their counts they found that the one and two nuclei cells were most frequent in the “bad” and “very bad” groups and decreased in the “good” and “medium” groups. In a small number of cases they found with a good clinical symp- tom complex, a very bad blood picture and “noted that shortly there- after the patient took a turn for the worse.” Ringer concludes that the Arenth count “is of a certain value, should not be abandoned and it will, in certain apparently favorable cases, correctly presage an unfortunate outcome, or vice versa.” The Arenth blood picture gives no indication of the extent of lung invasion nor of the stage of the disease; it is, hoivever, an index of the resisting power of the patient. Solis Cohen and Strickler conclude (quoted by Ringer) : “While the average index showed little change, in most of our individual cases the proportion of cells in the first two classes of Arenth seemed to be increased as the patient improved, and in a number of cases to be decreased as the patient grew worse.” Of 27 improving patients whose blood was exam- ined more than once, an increase in cells with one and two nuclei was ob- served in 22, and a decrease in 4. Among advancing cases there was an increase in 3, a decrease in 4, and no change in 2.” The figures of these observers are opposed to those of others. Differences in methods of count- ing the nuclei, a difficult process, must naturally be considerable. Miller and Reed, after considering the subject and making a large number of counts, believe that “the Arenth blood picture is of real value in prog- BACTERIAL DISEASES 237 nosis.” Miller and Reed report further that cases of pulmonary tubercu- losis which are doing badly, progressive or exacerbating, show the follow- ing blood changes: (a) Leukocytosis. (b) An increased percentage of neutrophils. (c) A diminished percentage of small lymphocytes. (d) A diminished percentage of eosinophils. (e) A marked shifting to the left of the Arenth blood-picture con- versely, changes in the opposite direction if any of the above factors are favorable. I fully agree with Ringer, that those who use the Arenth method will continue to use it, that it is simply one link in a chain which strength- ens prognosis, that blood pictures will never displace bedside findings in- cluding physical signs, that “he who places implicit confidence in its read- ings and bases his prognostic opinions chiefly thereon, will not infrequently be led into error.” The 'persistence of tubercle bacilli in the blood is always ominous. The more severe the infection, the nearer its termination, the more certain are we to find bacilli in the current. We do, however, find tubercle bacilli in the blood stream in incipient cases; but this is transitory as a rule. Liebermeister’s far-reaching study of this subject justifies conservatism before we conclude positively that the bacilli are true tubercle bacilli, for acid-fast bacilli were found by him in many non-tuberculous diseases in the blood, in children who did not react to tuberculin and in those appar- ently healthy. The fault lies in technique. Bandelier-Roepke conclude: “The significance of bacillemia in tuberculosis is not yet settled and positive conclusions are not justified.” The value of the opsonic index in the prognosis of tuberculosis has been considered in this chapter; as already suggested, the busy clinician will be unable to take advantage of it; in acute cases it may prove to be more valuable than in the chronic. Physical Signs Physical signs and stage of the disease must of necessity influence prognosis. It has been my object throughout this chapter to keep before the mental vision of the physician and student the enormous value of early recognition and its influence on prognosis. In the United States we con- sider “incipient cases” those with hut slight or “no constitutional symp- toms (including particularly gastric or intestinal disturbance or rapid loss of weight) ; slight or no elevation of temperature or acceleration of pulse at any time during the twenty-four hours.” “Expectoration usually small in amount or absent.” “Tubercle bacilli may be present or absent.” 238 SPECIFIC INFECTIOUS DISEASES “8Ught infiltration limited to the apex of one or both lungs or a small part of one lobe.” “No tuberculous complications.” Every fresh extension sufficient to make its presence manifest by posi- tive physical signs is a menace. The increase of moist rales, sputum, bronchial breathing, with increase in rapidity of heart, with or without decided rise of temperature, with or without tubercle bacilli, are proof of advancing disease. Dullness over large areas, with bronchial or broncho-vesicxdar breathing, with moist, large, or small rales, indicate activity of the tuberculous process. Cavernous and amphoric breathing, metallic tinkling, marked tym- pany, large and coarse rales, abundant tubercle bacilli and negative reac- tion to all tuberculin tests, are proof positive of the third and last stage of the disease. Many patients recover after fully developed pleurisy, effusion or even empyema. There is no stage save the terminal of the disease, in which a reparative process may not be stimulated; post mortems show healing processes fully established, fibrous bands, enclosing walls, the encircling and closure of cavities, the lining of pus pockets and their side-tracking, the formation of protective adhesions and a variety of processes by which nature seeks to arrest the disease, establish latency or cure it. Every deposit which persists at the apex of one or both lungs should be considered tuberculous from the beginning, and this conclusion should not be changed until there is proof positive of error. Deposits in the de- pendent parts of the lung are less likely to be tuberculous than those at the apex, but these too must be viewed with suspicion until a correct pathologic diagnosis can be made. All complications and depressing factors influence prognosis unfavor- ably. Age is a factor to be considered in the prognosis of tuberculosis. In children the course of the disease is rapid, as a rule, and offers a less favor- able prognosis than in the adult. Disseminated tuberculous disease, acute miliary, including brain invasion, is more frequent in early life than later. Prognosis is more favorable as we advance in life; after the 60th to 65th year we again approach the mortality and tendencies of early life. There is no time limit in tuberculosis. There are subjects who have been tuberculous during almost their entire lives and die of intercurrent disease late in life. Age Tuberculin Tests Tt will never be safe to consider the tuberculin tests too enthusiastic- ally, as some have done in offering the prognosis of pulmonary tubercu- losis. We do know that the reaction represents a phenomenon of sensitiza- BACTEKIAL DISEASES 239 tion; we know further that the majority of apparently healthy adults react to the Calmette, the Moro and the von Pirquet tests. The subcutaneous injection of tuberculin remains the very best method in use to-day for the detection of hidden tubercle deposit in the body. It is not without its dangers and is now used more for treatment than for diagnosis and prog- nosis. The conjunctival test (Calmette, Wolff-Eisner) demonstrates by positive reaction the presence of early tuberculosis in between 60 and 70 per cent of cases. Vaughn, Jr., in 160 cases of early tuberculosis, found positive reaction in 72 per cent. My figures with a large clinical material are not so high; they are in the neighborhood of 55-60 per cent. Bald- win’s 67 per cent; Wolff-Eisner 75 per cent. In my practice most favor- able cases of incipient disease and those in the second stage have given positive reactions to all tuberculin tests. I am using preferably the von Pirquet and Moro tests in private practice, though in a large experience with the ophthalmic test I never had an untoward experience. Others have been less fortunate. The tuberculin injection is not available in cases with fever and wasting. Active miliary tuberculosis rarely reacts to the tests. Positive tubercu- losis of any organ in which the tuberculin tests remain negative is less likely to progress favorably than those in which the reactions were active and positive. My experience with tuberculous meningitis, acute 'pneu- monic tuberculosis, tuberculous peritonitis without ascites and often with- out elevation of temperature, show only a small proportion of positive reactions; the protective principles have been exhausted, the prognosis is correspondingly bad. In my tuberculous wards at St. Joseph’s Hospital, where advanced and neglected pulmonary tuberculosis are received, it has been the rarest exception to find positive reactions. The von Pirquet test for prognosis in the adult is valueless, the ma- jority of healthy adults give prompt reactions. In children the von Pirquet shows the time of infection in cases held under observation, but is of indifferent prognostic significance. There are patients who fail to react during the early stage of pul- monary tuberculosis and whom it is impossible to sensitize. In the presence of clinical symptoms of tuberculosis with suspicion that the case is advancing and a negative tuberculin reaction, the prognosis is likely to be doubtful, usually unfavorable. I have never in my experi- ence found positive von Pirquet, Moro or Calmette in the midst of rapidly advancing tuberculosis. Latent pulmonary tuberculosis in the adult is likely to give positive reaction to the tuberculin tests, particularly von Pirquet. Rontgenoscopy The x-ray in the diagnosis and prognosis of tuberculosis has become indispensable, but a word of warning against hasty conclusions by the 240 SPECIFIC INFECTIOUS DISEASES inexperienced who have not learned to interpret pictures is not out of place. To be of any practical value the picture must always be interpreted by the expert who has trained himself by long practice for the work, aud who has had abundant opportunity to compare his conclusions with post mortem finds. So many errors have been made, that many are becoming skeptical and require but little discouragement to surrender this valuable method of diagnosis and prognosis. The more valuable results are obtained in chronic tuberculous phthisis and its associated changes. Solitary nodules and calcified deposits and glands are usually easily demonstrated. Unfortunately the Rontgen pic- ture is not absolutely dependable for early diagnosis, and negative results or suggestive shadows deserve less consideration than clinical data, includ- ing physical signs, with a thorough consideration of all that the case offers. Valuable data concerning the condition of the bronchial nodes for diag- nostic and prognostic use are given by x-ray examination. This area (hilus-bifurcation of trachea) is often suspected in cases where indefinite symptoms have followed the infections of early life, including measles, pertussis, pleurisy, lymphatic enlargements of the neck, and the true con- dition, if revealed early, may prove life-saving. Pleural effusion and nodular deposit, displacement of thoracic vis- cera, the size and position of the heart and diaphragm, all important, are frequently corroborated by x-ray examination. These conditions, wuth their influence on the progress of the individual case, can as a rule be studied and recognized without x-ray examination. There never will be a time when the well-balanced physician will surrender the results of pains- taking physical examination in favor of the revelations obtained from the Rontgenologist. The Rontgenologist demonstrates shadows only; what these are, what they mean to the pathologist and diagnostician, what their value for prognosis, is not easily determined and once more I must insist that the cautiously taken history, with a full consideration of the subjective and objective manifestations in the individual case, are needed to obtain rational and valuable data for prognosis. The Tuberculosis of Early Life The tuberculosis of children as it invades the lung is more likely to be disseminated, less likely to limit itself to the apices, is therefore often characterized by the more serious features of miliary deposit. The active disease in many is preceded by glandular enlargements and caseation, par- ticularly of the cervical glands, and we ought never to forget the enormous etiologic importance of the bronchial lymph-nodes. These may have been previously infected or the deposit of bacilli may take place during or fol- low any of the acute infections of early life. Changes in the mesenteric BACTERIAL DISEASES 241 glands with peritoneal invasion are not infrequent. These cases are always serious. Invasion of the bones and joints is more frequent than in the adult and precedes pulmonary tuberculosis in most cases. The development of amyloid disease, dropsies, and enlarged spleen is, in children with bone and pulmonary tuberculosis, characteristic of the last stage of the disease. The prognosis in children is materially in- fluenced by contact with, tuberculous parents. The mortality of early life has been changed by the improvement of social conditions; statistics will be still more favorable when there is a concerted effort which will make it possible to place the children of the active tuberculous in normal surround- ings. This not only influences the mortality of childhood, but will prevent latent deposit which may become active during the mature years of life. Other features of prognostic value influencing the tuberculous disease of the lung in children have been considered in the preceding pages. Atten- tion has been called to the frequency of tuberculous meningitis. Marriage As already shown, contact with tuberculous parents increases at once the chances of infection. Mothers who are tuberculous are a menace to their offspring; their children are more likely to be infected than are those of tuberculous fathers. The suckling of the tuberculous mother in whom the process is active is likely to develop some form of infection. I have been surprised to note the frequency of tuberculous meningitis under such conditions. The infection of the child is usually early. Latent tubercu- losis in the mother is often lighted to activity by pregnancy and childbirth. The extension or activity is greatest during the last half of pregnancy. My experience does not justify the nursing of a babe by a mother in whom the process has recently been arrested. Both will be likely to develop active tuberculosis. One of the most serious complications during preg- nancy or lactation is tuberculous laryngitis; this may develop in the mother in the presence of only limited lung disease. The prognosis is absolutely bad; the progress is rapid, with disorganization, painful ulcera- tion, and edema of the larynx. Dubois says: “If a woman threatened with phthisis marries, she may bear the first accouchement well; a second with difficulty, a third never.” Weinberg has shown that still births are in- creased 50 per cent in tuberculous mothers. Abortion, miscarriage, either criminal or spontaneous, increase the risk to the mother and invite the on- ward march of the disease. Subjects who have healed tuberculosis are likely to beget children who are ultimately burdened with some form of tuberculosis. Environment and social condition must of necessity remain important factors in the consideration of the influence of the tuberculous parent on offspring. 242 SPECIFIC INFECTIOUS DISEASES Diabetes complicating tuberculosis, whether acquired after or before infection, is always serious and finally leads to death; usually the diabetes is pre-existent. The association of chronic alcoholism and tuberculosis is always unfavorable, the latter process seeming to advance with unusual rapidity, tissues are non-resistant and are ready to break down on slight cause. Tuberculous or non-tuberculous meningitis is often the cause of death. Exophthalmic goiter, typical and atypical, may materially influence the prognosis. Brandenstein found in his clinical material in Hamburg that 20 per cent of the male tuberculous and 33 per cent of women had enlarged thyroids and 20 per cent of the men and 28.5 per cent of women showed positive evidences of exophthalmic goiter. Gangrene of the lung is always of serious significance. It is a late complication, usually appearing when the disease has advanced to cavity formation and, with added symptoms of sepsis, often delirium and a typhoid condition, the patient dies. The obese who develop tuberculosis offer little resistance as a rule. They are inclined to be anemic, the myocardium is promptly weakened and the disease usually advances rapidly with increasing evidences of cardiac insufficiency. Gouty conditions do not influence tuberculosis unfavorably; with these there is greater tendency to fibroid change in the lung and chronicity. Syphilis, particularly neglected cases with lowered resistance, offers a favorable medium for the advance of tuberculous disease. Tuberculosis is never favorably influenced by the addition of syphilis. It is not unusual to find acute tuberculosis shortly after syphilitic infection, and to see the rapid advance of the chronic form of the disease as well as the kindling of latent deposit to activity. If, on the other hand, tertiary syphilis is present and tuberculosis is acquired, the course of the latter may be unin- fluenced by the previous specific infection. The French have claimed a favorable influence on the tuberculous disease by the exhaustion of the syphilitic poison and the ultimate tendency of the tuberculous process to fibrosis and chronicity. That there are many cases of tuberculous disease of the lung and syphilis combined, in which we find not only positive bacteriologic evi- dence of the former, but establish the certainty of the latter by sero-diag- nosis, in which the mixed treatment (salvarsan and anti-specific drugs) gives satisfactory results which cannot be denied. The clinician is fre- quently surprised to find his prognosis favorably influenced in such cases by systematic and specific treatment. In the presence of tuberculous invasion of the lung, specific treatment and the Wassermann test are often justified, and should be used for their diagnostic and prognostic value. Complications BACTERIAL DISEASES 243 Tuberculous pleurisy will be separately considered; it is rarely absent where lung deposit is superficial. Pneumothorax due to the perforation of the lung, because of super- ficial cavity formation, is a frequent complication and may lead to sudden death. It may occasionally arise from the rupture of a superficial em- physematous patch. If pyopneumothorax follows, there may be a period of acute symptoms, exacerbation with high fever, rapid pulse and death, or the patient may rally and fall into a chronic condition in which all physi- cal evidences of pus and air in the pleural cavity continue, or he may add to his weight and live for a number of months. In a proportion of cases, if the disease is limited to one lung, the occurrence of pneumothorax may stimulate reparative processes, particularly fibrous growth, and prove salutary. Those cases in which the lung process shows early tendency to disorganization with acquired pneumothorax are not among the favorably influenced by the accident. One-half of all pneumothoraces are tubercu- lous. Atelectasis may, if widespread, seriously interfere with the condition of the patient. It is caused by the occlusion, of one or more bronchi, usually by cheesy masses, either formed in situ or transported from another part of the lung. Naturally the area supplied by the included bronchus collapses and the patient is robbed of the breathing surface. If there is much associated consolidation, the condition proves promptly serious; otherwise compensatory efforts are sufficient to relieve the embarrassment. Emphysema may result from the expansion of the lung in the neighbor- hood of tuberculous infiltration; its importance depends on the extent of the primary disease, its stage and the ability of the heart to come to the rescue. As a rule limited emphysema need cause but slight concern. Purpura with pulmonary tuberculosis is always a grave symptom; it is likely to be associated with the end or cachectic stage of the disease. In some, it is an evidence of acute exacerbation and is not infrequently asso- ciated with active febrile movement and with rapid loss of strength. Death may follow in a short time or, as Cruice has reported, the patient may recover. Thrombosis is an occasional complication which may, within a few hours or days, end life. Thrombi may be multiple and extensive. Large numbers of pulmonary vessels may be plugged; at the same time one or more of the larger vessels (renal, branches of the portal or iliacs) may also be occluded. The complication is always grave. Healed and latent tuberculosis may without known cause suddenly become active. Fresh infection is not among the impossibilities. It must be assumed that the patient in whom the tuberculous process has been halted is less resistant than the previously uninfected, and, if he is to re- main free from relapse or fresh infection, he must guard himself with greater caution than is needed by the perfectly normal subject. 244 SPECIFIC INFECTIOUS DISEASES III. Fibroid Phthisis Fibroid phthisis is a tuberculous disease .of the lung characterized by the development of new connective tissue. Such a process is rarely acute, almost always chronic and continues without marked constitutional symp- toms during many years with consecutive change in the heart, veins, and distant organs. I will discuss the subject under the following classifi- cation : A. Acute Fibroid Phthisis. B. Chronic Fibroid Phthisis. (a) Tuberculous ab initio. (b) Ffin-tuberculous with final tuberculization. (c) Chronic interstitial pneumonia sine tubercle. A. Acute Fibroid Phthisis Cases of acute fibroid phthisis, in contradistinction to the chronic and usual form of the disease, run a virulent and rapid course. Friedrich Muller has directed attention to cases of this nature which are not usually recognized during life. They begin with outspoken symptoms, including fever and malaise and rapid loss of strength. The tuberculous infiltrate is not encapsuled by the connective tissue proliferation, but there is prompt dissemination and increase of consolidation, tuberculous bron- chitis and bronchopneumonia, or there may be prompt development through the lymph channels of miliary invasion of both lungs. The characteristic features of the disease are the disseminated growth of connective tissue and the failure to encapsulate tuberculous herds with rapid deposit finally in both lungs, in most cases. These patients die in from 6 to 12 months and are, as a rule, between 20 and 30 years of age. Muller calls attention to the frequency of these cases, in those inherently weak, with inherited predisposition, deformed chests, after typhoid, measles, influenza, with alcoholism, diabetes, and after pregnancy. Chronic fibroid phthisis may have acute exacerbations of serious im- port lighted by influenza, bronchitis or other added infections, which in many respects resemble the acute type just described with a simliar out- come. B. Chronic Fibroid Phthisis (Chronic Fibroid Phthisis, Chronic Tuberculous Pneumonia, Tubercu- larized Pneumonohoniosis, Chronic Interstitial Pneumonia-tuber- culous) (a) Tuberculous ab Initio.—These cases are of long duration; patients usually present a history of acute disease of the pleura, bronchopneumonia, bronchitis or measles, whooping cough, influenza or other infection, which BACTERIAL DISEASES 245 has been followed by persistent cough, scant expectoration as a rule, during many years. During this long period the lung process, has advanced insidiously, the fibrous growth has gradually increased, cavities which may have existed, resulting from chronic ulcerative phthisis, have become encapsuled, the pleura is enormously thickened and, as the disease advances, one or both lungs show cirrhotic changes in various parts, and the lower lobes may be converted into masses of connective tissue. In some cases bacilli are long absent and the true condition can only be surmised; ultimately bacilli appear. Chronic fibroid phthisis leads to secondary changes materially influenc- ing the comfort of the patient during years before the end, which may be due to intercurrent disease. Among the changes are enlarged lymph nodes, bronchial dilatation {bronchiectasis), atelectasis and the evidences of an overworked right heart in dilatation of the right ventricle, often dilatation and hypertrophy of the entire heart; in the terminal stages evidences of engorged portal circulation, enlarged liver, with or without ascites, cya- nosed kidney, chronic gastritis, enlarged spleen and hemorrhoids. These patients as already suggested may, under changed or favorable, surround- ings, live to old age. Many live 20 and 30 years after the onset, and few die before the 10th year of symptoms. When the disease follows measles, whooping cough or rachitis in early life, it is difficult, as Miller has said, to tell what becomes of these chil- dren, for the majority are hospital inmates. If they are followed in pri- vate practice, as many are, with “chronic cough,” it will be found that in middle life and later some develop or have developed chronic fibroid phthisis with dilated hearts, and the other and usual consecutive changes. (b) Non-tuberculous Fibrosis with Final Tuberculization.—These forms, as also chronic interstitial pneumonia sine tubercle, are intimately associated with conditions which continue to serve as irritants during many years and will receive fuller consideration in the chapters on Chronic Interstitial Pneumonia and Zenker’s disease or the pneumono- konioses. In considering the prognosis of non-tuberculous fibrosis with final tuberculization, we must include those cases of fibroid change in the lung, either local or general, which follow healed tuberculosis, or are a part of the reparative process, diffuse interstitial pneumonia, chronic broncho-pneumonia, chronic pleurisy with adhesions and ultimate connect- ive tissue overgrowth in the lung, in which tuberculization follows. These cases usually offer a good prognosis so far as life is concerned; they con- tinue during many years before there are evidences of tuberculous infection, with all symptoms aggravated during the winter months, are materially relieved during warm weather and under favorable climatic conditions. The secondary changes mentioned under tuberculous ab 246 SPECIFIC INFECTIOUS DISEASES initio, occurring in late stages, are likely to develop with this form of chronic phthisis. The addition of the tuberculous element influences the prognosis as a rule, duration depending upon many conditions. If there are acute exacerbations with fever, evidences of tuberculous broncho- pneumonia, or if large areas of consolidation with rapid pulse and dissemi- nation or associated miliary deposits are present, life is threatened and is usually shortened. In some cases with tubeculization there is only gradual progression; there seems to be a tolerance which prevents rapid or far-reaching deposit; the tuberculous herd is limited, may become encap- suled by the interstitial growth, and life is not materially shortened. If the disease is complicated by hemoptysis, and this in turn by fever —an indication of bronchopneumonia—the process is likely in most cases to advance and undermine the strength of the patient. Even after such complications and symptoms I have seen patients fall into their previous condition of chronic invalidism and live comfortably during many years. When there are evidences of cardiac insufficiency with dropsies, or marked changes in the portal system with jaundice (occasional), but little improvement is to he expected; death will not be long postponed. (c) Chronic Interstitial Pneumonia (Sine Tubercle).—This condition is non-tuberculous and will be considered with the Diseases of the Lung. (Chronic pneumonia, cirrhosis of the lung.) In no other disease is the physician more directly responsible for the outcome than in pulmonary tuberculosis. He must he willing to assume responsibility. Superficial examination, procrastination, failure to give the patient every advantage of existing doubt, in the incipient stage of the disease, apathy in the study of the social conditions of the sick, the lethargy of the public because of failure of the physician to educate and arouse it, remain among the leading causes of defeat.

Tuberculous Pleurisy It may be assumed that at least 50 per cent of all pleurisies after the fifth year of life are tuberculous. Physical signs of dry pleurisy with associated pain at the apex argue in favor of pulmonary tuberculosis and tuberculous pleurisy. Vincent Bowditch found that, of 90 patients treated for pleurisy by the elder Bowditch, 32 and one-tliird finally died of tuberculosis. Barrs of Leeds reported 57 cases of pleurisy in which 21 developed tuberculosis. Salonove-Ipin had 301 pleurisies of which 84 became tuberculous. Of 88 cases treated at the Johns Hopkins Hospital, 30 later developed tubercu- losis. Of 131 cases, Osier found 32 to be tuberculous (24.4 per cent) at post mortem. Landouzy claims that 98 per cent of all so-called pleurisies “due to cold” are tuberculous. Stinzing believes that over 50 per cent of all pleurisies are tuberculous. Extreme figures are given by Jakob and Pannwitz, who claim 10 per cent, and v. Sokolowski, who found only 2.8 per cent to be tuberculous. The safe figures according to an estimate made from an analysis of cases in private and hospital practice by the author, places the percentage of pleurisies positively shown to be tuberculous at 30-35. Tuberculosis, if it follows initial (?), supposedly uncomplicated pleurisy, develops in an active form within five years in 50 per cent of the cases. R. C. Cabot in 300 cases at the Massachusetts General Hospital found 117 to have died within 5 years of tuberculosis. Hedges followed 130 cases of pleurisy treated at St. Bartholomew’s Hospital and found 40 per cent with fully developed tuberculosis in seven years. As a rule, the immediate prognosis of tuberculous pleurisy is good; in many cases, how- ever, the remote prospect becomes a source of anxiety during many years. 248 SPECIFIC INFECTIOUS DISEASES The frequency of effusion with tuberculous pleuritis is shown by an analysis of Allard and Koester’s material. There were 514 pleurisies with effusion among 2133 cases of pulmonary tuberculosis. Pleurisy of early life (before the fifth year) is not often tuberculous. Allbutt gives the in- cidence as 1 in 10 and “even of these the pleurisy may be only incidentally associated with a tuberculous focus, or the tubercle may be a secondary consequence of a protracted empyema.” The larger number of tuberculous pleurisies are secondary to existing puliponary tuberculosis or are a part of general miliary infection. In cases which have etfery appearance of being primary the chances are that the pleural infection followed superficial lung tuberculosis which was in- active. Men develop tuberculous pleurisy oftener women (65-35, Bande- lier and Roepke, 1. c.). Adhesions which follow dry pleurisy may have a salutary effect on the progress of existing tuberculosis; indeed, many with truth consider it “al- ways a conservative and useful process” (Osier). The formation of dense adhesions may protect against pneumothorax, may also stimulate interstitial growth and encourage chronicity. Dry pleurisy with but few exceptions runs a favorable course. A limited patch of dry pleurisy over a consolidated area, with persistence of fever, occasional chills and sweats, must always be considered evidence of activity. Latham makes this unqualified statement: “The great majority of attacks of pleurisy in young adult life are tuberculous in nature. If this fact were appreciated sufficiently, and, still more, if all cases of pleurisy which cannot be shown to be non-tuberculous, were regarded as tuberculosis, a large number of cases of pulmonary disease would be prevented.” Cases of tuberculous pleurisy, in which the condition is early recognized and rationally treated (sanatorium, etc.) rarely develop active tuberculosis in later life. Latham and others believe that “a greater degree of immunity is produced, and that these patients are less liable to consumption subse- quently than the other members of the community.” Failure to recognize the significance of tuberculous pleurisy, on the other hand, increases subse- quent dangers, including further lung invasion. The French report pulmonary consumption widespread in later life in not less than 75 per cent of tuberculous pleurisies. In some cases tuberculous pleurisy may not finally be associated with more than limited and superficial pulmonary invasion, but tuberculosis of the spine or joints may develop or other distant infection may prove to be a serious complication. Invasion of the bronchial glands and pleurisy may be followed by periods of latency of the tuberculous process but remains a menace. Tuberculous empyema, unless treated early, may include persisting sinuses and, as mentioned in the chapter on Purulent Pleurisy, may lead BACTERIAL DISEASES 249 to amyloid disease. Tuberculous pleurisy does not often lead to empyema when modern methods of treatment are used. Pneumothorax and pyopneumothorax may result from the breaking of adhesions over cheesy herds or cavities or the separation of an adherent pleura. The significance of this complication is always serious in ad- vanced cases and has been considered in connection with Chronic Pul- monary Tuberculosis. Retractions and deformities of the chest are not as frequent as form- erly, because of early radical treatment and pulmonary gymnastics; in some cases pulmonary fibrosis follows and with bronchiectasis, the patient falls into a condition of chronic invalidism which may continue during many years. In acute miliary tuberculosis, the pleura may be studded with deposit, a part of the disseminated disease, in which the prognosis is always bad. References Allard & Koester. Hygiea. Oct., 1911.

Parotid and Thyroid Tuberculosis The prognosis of tuberculosis of the parotid is good. The disease is usually primary, superficial and amenable to surgical and early treatment. Tuberculosis of the Thyroid Tuberculosis of tlie thyroid is rarely primary, it is usually acute and part of a general miliary infection. In children, with acute infection the thyroid rarely escapes tuberculous deposit. There may be no subjective or objective evidences of thyroid disease. Secondary nodules isolated in the thyroid may calcify or heal without causing symptoms. Hector Mackenzie found but one case of Graves’s disease in a tubercu- 250 SPECIFIC INFECTIOUS DISEASES lous subject, while on the other hand he cites L. Levy who had “13 cases of Graves’s disease among 170 tuberculous patients ; such an experience must be quite exceptional.” My experience is in accord with Hector Mac- kenzie, for in a large experience with typical and atypical exophthalmic goiter and tuberculosis, I have rarely found these complicating each other. References Levy (L.). Quoted by Allbutt & Rolleston. 2. ed., iv, part i, 361. Mackenzie {Hector). Idem., 361. 5. Nasal Tuberculosis Nasal and oral catarrh, non-tuberculous, are frequently annoying and aggravate cough during all stages of pulmonary or laryngeal tuberculosis. The “dry catarrh” of the consumptive interferes materially with his com- fort, though it is at no time threatening to life. Ozena opens the avenues to tuberculous infection and may finally be- come tuberculous. Single tuberculous ulcers settle by predilection on the cartilaginous septum low down and are amenable to treatment. Tuberculoma and dif- fuse tuberculous infiltration of the nasal mucosa with final ulceration, may prove destructive, leading to perforation and loss of bone. If the lesions are limited, radical treatment will overcome them; if, however, infiltrating or multiple, single lesions may heal, but relapse and fresh ulcerations are the rule. Naturally the prognosis must depend upon the associated conditions, particularly upon the extent of the primary disease, and the general condition and social status of the patient. Post nasal, pharyngeal tuberculosis is not prominent during life; there are but a few symptoms which lead to its discovery. The condition is a part of the general infection. Post mortem ulcers of the pharynx are not infrequently found. During life their presence has no material bearing on the course of the disease. 6. Laryngeal Tuberculosis For the purpose of the internist it may be concluded that: (a) Primary laryngeal tuberculosis is exceedingly rare, but is among the possibilities. It may be associated with perichondritis or may limit itself to the mucosa and submucous tissue. (b) Laryngeal tuberculosis is as a rule a secondary process. Its favorite seat is on the anterior surface of the posterior laryngeal wall and the arytenoid cartilages. (c) Laryngeal tuberculosis shows prompt tendency to infiltration of the underlying tissues and to ulceration. BACTERIAL DISEASES 251 (d) Miliary deposit in the larynx is not exceptional. (e) Ulcerations may be single or multiple, and “tuberculous tumors” (“tuberculoma”) may form with associated edema of the glottis. (f) The tuberculous laryngitis of the terminal stage of pulmonary tuberculosis is a potent factor in hastening the end. (g) Laryngeal tuberculosis with pulmonary phthisis is rapidly ag- gravated by pregnancy and childbirth, and offers an unfavorable prog- nosis, so bad, that laryngologists have often considered the advisability of inducing abortion to save the life of the mother. Robert Levy makes the following statement: “I know of no disease into the prognosis of which so many items enter as into that of laryngeal tuberculosis. The stage of the affection, the nature of the lesion, the situation of the lesion, the complication, the asso- ciated general or pulmonary involvement, the environment of the patient, the social position, all and more must enter into a consideration of the possible termination.” The spontaneous healing of laryngeal tuberculosis is so rare as to deserve but little consideration in offering a prognosis; a view which most modern laryngologists entertain. At the meeting of the Verein Deutscher Laryngologen in 1911, Dreyfuss, Kummel and Rumpf, held opposite views. Killian contended that these cures were found in those who lived in the open air, the patients had practically received the modern treatment for the primary disease. Where laryngeal tuberculosis exists with pulmonary consumption, the leading data for prognosis must always be given by the latter, i. e., the primary disease. Moderate pulmonary invasion with limited laryngeal infiltration or ulceration offers a good prognosis. Fever, anorexia, dys- phagia, edema of the glottis, with pulmonary and laryngeal tuberculosis are all unfavorable and hasten the end. Early recognition of laryngeal tuberculosis and prompt treatment, local and climatic offer great encouragement. Levy quotes Briill who “found 58 per cent of his cases clinically cured when they left the sani- torium, and that of these, 31 per cent remained cured.” Men show greater tendency to cure than women, 30 per cent against 26 per cent. There are many chronic cases in which there is, as the result of local and climatic treatment, cicatricial repair of laryngeal lesions with result- ing deformity, consecutive hoarseness and noisy breathing. Patients may live many years in this condition. Ko case of pulmonary tuberculosis is favorably influenced by the advent of laryngeal invasion; the danger is greater when the disease is active; tubercle deposits are numerous and there is ulceration with edematous swelling. With infiltration only, the progress of the lung disease is not materially hastened. I know of no case of cure in my practice in which laryngeal and advanced pulmonary tuber- culosis were coincident. 252 SPECIFIC INFECTIOUS DISEASES We ought never to divorce ourselves from the consideration of the in> fluence of predisposition and the social status of the patient in reaching safe conclusions for prognosis. Advanced larnygeal lupus offers an unfavorable prognosis; limited in- filtration may yield to radium or mesothorium. Tracheal and Bronchial Tuberculosis Ulceration of the trachea and larger bronchi are usually associated with advanced laryngo-pulmonary tuberculosis, associated with enlargement and caseation of the bronchial glands, always (practically) secondary and terminal manifestations, in which the end is not long postponed.

Tuberculosis of the Digestive Tract The Lips.—Labial ulcers are rare; they are occasionally found in the advanced stage of laryngeal or pulmonary tuberculosis, and, barring the pain which they cause, have no bearing on prognosis. When they are present early, the diagnosis may prove difficult without inoculation or bac- teriologic tests. The Tongue.—Tuberculous ulcerations of the tongue may be present with or without lip ulceration. These lesions show characteristic tubercle deposit, and ulceration soon follows with uneven edges, without the “punched out” appearance of the specific ulcer. Lupus of the tongue and lips is less likely to ulcerate than is the usual form of tuberculous deposit. Tuberculosis of the lips, tongue or tonsils, may be either primary or secondary and is usually caused by the human type of tubercle bacillus, though there are occasionally positive evidences of bovine infection. Tuberculosis of the tongue with invasion of the surrounding glands, often extensive, is not infrequent and is usually a part of a widespread process which is destructive and fatal. The Tonsils.—The tonsils are important organs in conveying tuber- culous disease. They harbor bacilli of tuberculosis, transmit them to the surrounding glands and thus become directly responsible for the dissemi- nation of the disease. During active tuberculosis the tonsils are always found to hold bacilli and often show remnants in chalky deposits of healed tuberculosis. Tonsils may hold tubercle bacilli during long periods with- out recognizable pathologic change in their structure. There can be no doubt of the fact that the tonsils of children often than adults furnish a BACTERIAL DISEASES 253 focus for general tuberculous infection through the cervical lymphatics; these facts have been fully corroborated by Latham and Schlenker. To prevent descending infection, all suspected tonsils should he excised early. The tonsils are often invaded during pulmonary and general miliary tuberculosis without much enlargement or disagreeable symptoms or ulcer- ation. In occasional cases, where there is marked tendency to breakdown of tissues, small or large ulcers form in the tonsils and soft palate. With laryngeal tuberculosis in the terminal stage of the disease, ulceration, edema and swelling of the tonsils and of the mucosa of the upper air passages add to the discomfort of the dying patient. The prognosis of primary tonsillar invasion is good. With tonsillar and pharyngeal invasion, as with nasal tuberculosis, the larger elements which influence prognosis are the extent of the primary disease, the resist- ance of the patient and the many other factors to which I have referred in the general consideration of tuberculous disease. It must be remembered that primary, labial or oral tuberculosis may promptly lead to infection of the intestinal and respiratory tract. The Esophagus.—Esophageal tuberculous ulcers occasionally compli- cate distant, usually pulmonary or intestinal tuberculosis, offer few or no symptoms, and are usually overlooked during life. If symptoms are present, the general process is usually advanced and the prognosis is corre- spondingly bad. The Stomach.—Reference to the dyspepsias of tuberculosis has been frequent in considering the subject generally, and their association with the acute and chronic forms of pulmonary tuberculosis. Intolerant stom- achs are always a source of anxiety, particularly when during the incipient stage of pulmonary tuberculosis all other factors, including environment, are favorable and the patient is handicapped because of the revolting stomach. True tuberculous lesions are so rarely found in the stomach (tubercu- lous ulceration, etc.), that they demand no consideration in this work. (See statistics of Melchior, Fredrichs, Diirck, Simmonds, Glaubitt and others in Bandelier and Roepke, 1914, p. 414). Chronic gastritis, due to stasis, may add an element of depression during the advanced stages of pulmonary tuberculosis with insufficient heart strength. Acute gastritis reduces the strength of the consumptive; it may recur at intervals. With miliary tuberculosis (general), the stomach is frequently the source of uncontrollable symptoms; malnutrition with associated anemia, high temperatures often, rapid pulse, with advancing evidences later of intestinal involvement, lead to death. In many cases the prognosis is still further influenced by persistent lack of free hydrochloric acid in the gastric juice. Intestinal Tuberculosis (Tuberculous Enteritis).—(a) Primary. 254 SPECIFIC INFECTIOUS DISEASES Most primary tuberculous infections of the intestine are found among chil- dren and are due to tuberculous milk, meat, or contamination of food with other tuberculous material. In primary intestinal tuberculosis in children there may be no symptoms of pulmonary disease; the child presents the symptoms of acute or subacute gastro-enteritis, the wasting is usually rapid, loss of strength prompt, fever and increasing anemia striking; the weak- ness is often out of proportion to the diarrhea. Enlargements of the mesenteric glands are often palpable as the disease advances. In children there is rarely intestinal perforation and there is no tendency toward spontaneous repair. There is in some cases associated tuberculous lymph- angitis with deposit of small tubercles on the serosa over the intestinal ulcers. Primary tuberculosis of the intestine is associated with greater in- vasion of the intestinal glands than is secondary enteritis, which shows but little tendency to more than slight swelling of the mesenteric glands, rarely nodules or caseation. The prognosis of the primary intestinal tuberculosis of early life is absolutely bad. The duration of life varies from 6 to 8 weeks to as many months after the onset of symptoms. (b) Secondary tuberculous enteritis is present in all cases of advanced pulmonary tuberculosis, according to Albrecht, in which there is cavity formation. In these cases isolated and characteristic ulcers are found, or there may be multiple ulcerations throughout the small and large intestines. As already mentioned in connection with the primary tubercu- lous ulcers, the secondary enteritis is not associated with more than slight enlargement of the mesenteric glands; there are but few or no nodules and there is rarely caseation. There may be far-reaching intestinal tubercu- losis with but slight deposit at one or both apices, which may run a rapid course with all of the symptoms of general infection (Piissler). Secondary enteritis is probably due to the swallowing of tuberculous sputum. Unquestionably intestinal infection is promptly associated with tubercle bacilli in the lymph of the thoracic duct and the blood of the portal system, and hence leads to flooding of the organism with tubercle bacilli which may have some influence on immunization or, what is more probable, causes metastases in the already infected lungs and other organs of the body (Fischer). Intestinal tuberculosis through the blood and lymph stream causes the deposit of masses of grayish tubercle nodules in the spleen, kidney and adrenals. Hot all ulcers found in tuberculous subjects are tuberculous; some may be due to associated mixed infection; the influence on the course of the disease is not materially different, for with the tuberculous as well as pyococcous ulcerations the resulting colliquative diarrhea is equally ex- hausting, and with increasing evidences of depletion, these patients die of exhaustion, enormously emaciated; often there are evidences of amyloid degeneration. Chronic tuberculous enteritis may follow an early stage of pulmonary BACTERIAL DISEASES 255 tuberculosis, when it is due to changes chargeable to toxemia, stasis, atrophy, atony or inflammatory swelling of the mucosa (Bandelier and Boepke). In this class of cases the immediate prognosis is favorable, for these patients may live, comparatively comfortable during many years unless the primary disease makes rapid progress; they may be favorably influenced by diet and climate. Hippocrates’ dictum may be accepted as true to-day. “Diarrhea added to consumption is a fatal complication.” By this is naturally meant tuberculous enteritis with colliquative diarrhea. In occasional cases, symptoms of intestinal stricture with coiling of intestines, follow tuberculous invasion of the ileo-cecal region, or there may be multiple constrictions due to ulcerations wLich have followed faulty healing processes. These structures are clinically often mistaken for carcinoma. The neighboring lymphatics are likely to be enlarged and adhesions are not uncommon. They may be either of primary or second- ary origin; about are favorably influenced by operation. In some cases the course is chronic. The Liver.—Fatty degeneration of liver tissue, either widespread or limited, is one of the more frequent complications of pulmonary tubercu- losis. Liver cells are surcharged with fat, and enlarged. In advanced cases the entire liver may become fatty. As the fat of the body is con- sumed, the deposit in the liver increases, hence prognostic conclusions are easily reached in the presence of subjective and objective symptoms of fatty liver. Lorentz proved that among the emaciated marasmic tuberculous subjects, 34.8 per cent were found with fatty livers, while this condition was absent among the acute tuberculous infections. Amyloid degeneration of the liver is always a late manifestation of chronic tuberculosis, is associated with similar change in other organs (spleen, kidney, adrenals, bone, etc.) and with dropsies. Cirrhosis of the Liver and Tuberculosis.—The examination of the material at the Strassburg Medical Clinic showed 21 cases of tuberculosis among 85 cases of cirrhosis of the liver, 25.5 per cent. Lorentz among 4,331 post mortems found 111 cases of cirrhosis and among these 22 cases of tuberculosis. Among 59 cases of cirrhosis as the leading cause of symptoms there were 6 cases of tuberculosis, and, in 52 cases of cirrhosis considered incidental, tuberculosis was the primary disease among 16. It is positive that cirrhosis of the liver invites tuberculous diseaseJ on the other hand it may be concluded with certainty that primary tubercu- losis does not often lead to interstitial hepatitis (cirrhosis). Widespread or limited tuberculosis in the presence of advanced cirrhosis of the liver may be safely considered to have followed and not preceded the latter disease. The statistics (Bandelier and Boepke) prove the incidence of tuber- culosis with cirrhosis in 20 per cent of cases, while cirrhosis following tuberculosis is found among less than 2 per cent of the former. Bolles- 256 SPECIFIC INFECTIOUS DISEASES ton states that in 706 fatal cases of cirrhosis collected from literature, 209 (or 29.6 per cent) presented some evidence of tubercle; (the general incidence of tuberculosis in deaths from non-tuberculous disease is only about 13.5 per cent). Tuberculous lesions were found in the lungs of 22.6 per cent of a series of 584 cases of cirrhosis. Pulmonary tuberculosis is the direct cause of death in from 12 (Kelynack) to 14.5 (Rolleston and Fenton) per cent of patients with cirrhosis. In 9 per cent of the series of 584 cases there was peritoneal tuberculosis. As to cirrhosis following tuberculosis, Rolleston believes that “there is no reason to think that genuine cirrhosis of clinical importance is primarily produced in this way.” Cirrhosis with tuberculosis runs a rapid course with marked ascites, usually hemorrhagic. Pain and tenderness are slight as is jaundice also. Pleural effusion, usually double, adds to the suffering of the patient and hurries the end. Primary tubercle nodide in the liver is exceedingly rare; usually found post mortem. If palpable and large it may simulate carcinoma. F. Krause reports a unique case of a man, age 33, which he operated success- fully for primary tubercle of the liver in which the original diagnosis was uncertain; both cancer of the liver and transverse colon had been suspected. Microscopic and bacteriologic examination proved the growth to be tuber- culous. There was prompt and uneventful return to health. Pertik in 1904 found but 19 similar cases in medical literature. Orth reports two cases in both of which he was thoroughly convinced that the growths were primary; in the first tuberculous peritonitis finally developed. With miliary tuberculous generally disseminated, the multiple deposits in the liver are simply a part of a general process which usually leads to death. With advanced chronic ulcerative pulmonary tuberculosis the liver may hold several large caseous nodules; often there are nodules in the spleen at the same time, while the intestinal glands are ulcerated and the intestines are involved. With such lesions death is not long postponed. With acute tuberculosis the enormous bacillemia naturally leads to liver tuberculosis, though the liver function unquestionably tends to destroy tubercle bacilli and other bacteria brought to it through the blood stream and thus prevent its own tuberculization. Tuberculous perihepatitis complicates tuberculous peritonitis fre- quently, but adds little to its seriousness. The prognosis of all forms of liver tuberculosis must be considered to be serious, for it may almost always be assumed to be a part of a wide- spread and progressive process. The Gall-Bladder.—The gall-bladder may be the seat of primary tuber- culosis with other ulcerative and chronic processes, or the bladder and bile passages may become tuberculous in association with pulmonary, peri- toneal, acute general miliary, or the tuberculous invasion of any of the BACTERIAL DISEASES 257 abdominal organs. Primary tuberculosis of the gall-bladder offers a good prognosis when operated early; naturally the diagnosis will as a rule be made by accident only. Ischio-rectal tuberculosis has already been mentioned and I must repeat that when an early complication of any form of distant tuber- culosis, its radical treatment can have only a salutary effect. The persistence of the discharge is always a weakening drain. Superficial treatment without the removal of the tuberculous, i. e., fistulous tract, is useless. I have never known in my experience of the exacerbation of lung symptoms after the cure by operation of tuberculosis of the ischio-rectal fossa. Ischio-rectal abscess is often an evidence of primary and local tuberculosis (Eisner), and offers an excellent prognosis when radically treated. Such treatment will often prove life saving, for in the predis- posed the ischio-rectal fossa is a favorite seat of primary tuberculous disease. References Albrecht. Frankf. Z. f. P., 1, 1907.

Tuberculous Peritonitis The dictum of Louis (1825) that chronic 'peritonitis is usually of tuberculous origin has been accepted by the profession. Tuberculous peritonitis may be— (a) Miliary peritoneal tuberculosis. (b) Chronic tuberculous peritonitis. (c) Chronic fibroid tuberculous peritonitis. It is difficult in the individual case to reach positive conclusions con- cerning the focus from which the peritoneal disease spreads. A large num- ber of cases w7ill always remain problematic. It is safest for our purposes to conclude that in the larger number of cases the disease spreads from a preexisting deposit; that in over 50 per cent of cases in women it is a part of genital tuberculosis; that the spread from the Fallopian tubes is most frequent; that in children the intestines may supply the infection; that tubercle bacilli may pass through the intestinal wall to the perito- 258 SPECIFIC INFECTIOUS DISEASES neum; that there is no form of pulmonary or other tuberculous disease with which secondary peritonitis may not develop; that the peritoneum may be invaded in a process of multiple tuberculous periserositis with the pleura, pericardium and occasionally the meninges. The terminal stage of chronic cirrhosis of the liver may be compli- cated by an active peritoneal tuberculosis. Osier presents his statistics showing the disease twice as frequent in females as in males (131-60) and in 357 cases which he collected 27 were under 10 years: 75 between 10 and 20 years. 87 “ 20 “ 30 “ 71 “ 30 “ 40 “ 61 “ 40- “ 50 “ 19 “ 50 “ • 60 “ 4 “ 60 “ 70 “ 2 above 70 years. He also found the disease more frequent among blacks than whites in his service at the Johns Hopkins Hospital. Borschke, in 4,250 autopsies of which 1,393 were tuberculous, found 226, or per cent, in which the peritoneum was involved. These statistics vary in different sections; thus Hothnagel makes the statement that his experience in Vienna proved the peritoneum to be involved oftener than in Germany. The experiences in the United States prove the asso- ciation of peritoneal with other tuberculous infections in from 10 to 15 per cent of autopsied cases. (a) Miliary Tuberculosis of the Peritoneum In these eases there is hematogenous infection, far-reaching, deposit of thousands of millet-seed sized tubercles on the peritoneum and on the liver and the spleen, with or without ascites; usually the latter is limited and likely to be serofibrinous, bloody or purulent. There may be circum- scribed areas of flatness due to sacculation. In these cases there are usually, as the disease advances, abundant adhesions, anatomic evidences of perihepatitis and perisplenitis. The disease may progress with marked wasting and little fever, or there may be decided febrile movement, pro- gressive anemia, rapid pidse: the course is acute and rapid. When peritoneal tuberculosis is a part of a general infection, the local symptoms may be marked or remain unnoticed because of the prominence of the changes in other organs. Diarrhea, fever and rapid pulse are occa- sionally prominent and an unfavorable combination. Severe pains with circumscribed areas of dullness and evidences of adhesions, are at times associated with ballooning of the intestines, evidences of partial constric- tion, chronic obstipation, alternation of constipation and diarrhea, with progressive loss of strength and flesh. This complex presents factors which BACTERIAL DISEASES 259 influence prognosis unfavorably. The greater the ascites with miliary de- posit, the better is the prognosis; this conclusion may be accepted without hesitation. Peritoneal miliary tuberculosis, a part of a general tuberculosis, with vomiting, pain and tympany is always serious and offers a bad prognosis. Miliary tuberculosis limited to the cecum,, simulating acute appendicitis, when promptly treated, offers a fair prognosis during the active years of life. Cases beginning with symptoms of enteric fever, without marked lung invasion, with occasional rigors, sometimes a remittent type of fever with slight ascites, when recognized early and radically treated, offer a fairly good prognosis. Ascites in children with acute abdominal symptoms is always suggestive of acute peritoneal tuberculosis; these cases are easily diagnosticated and their progress is usually favorable, if radically treated. My experience with the disseminated and mixed forms of peritoneal tuberculosis in children, caseous, glandular deposit and miliary disease, has been unusually favorable. I number among those perfectly cured and grown to manhood a good number, in whom, during early childhood, at the time of operation, the disease was so extensive as to justify only the gloomiest forecast. The prognosis of miliary tuberculous peritonitis is much better in children than in the adult. Positive evidence of active tuberculosis elsewhere than in the abdomen reduces the chances of recovery. The more acute the onset the more unfavorable the prognosis. Murphy disagrees with this conclusion. Rol- leston calls attention to purpura (cutaneous hemorrhages) and diarrhea as “very grave indications.” Mon-febrile cases in adults with negative tuberculin reactions have in my experience been uniformly fatal. (b) Chronic Tuberculous Peritonitis (Caseating and Ulcerative) I have been encouraged to believe that cases which give prompt tuber- culin reactions (cutaneous and subcutaneous) offer a correspondingly good prognosis. The fewer associated complications present, the better is the prognosis. The greater the ascites, the better the prognosis; bad when hemorrhagic or purulent. The less the diarrhea, the more favorable is the outlook. Associated Addisons symptom complex (suprarenal disease) adds decidedly to the dangers and reduces the chances of recovery. Mixed infection, causing fever, night sweats, an unfavorable blood pic- ture (Arenth “Verschiebung”) and marked leukocytosis argue against recovery. Favorable environment is a decided factor in preventing re- lapse after latency or apparent cure. The future of the patient depends 260 SPECIFIC INFECTIOUS DISEASES very largely on the social conditions which prevail, for with peritoneal this is as important as with pulmonary tuberculosis. Many of these cases offer but few symptoms, run a chronic course cov- ering many years, during which the patient remains in statu quo, with- out ascites but with many adhesions and considerable thickening. The majority of cases run their course without ascites; the disease may be subacute or it may prove to be the final stage of an acute miliary tuber- culosis. A small proportion of cases develop intestinal symptoms; there may be moderate ascites, adhesions and succulation, evidences of partial intestinal obstruction from bands; the disease may remain afebrile dur- ing long periods; chronic invalidism with indefinite symptoms is not unusual. In occasional cases the retrograde process begins with acute exacerba- tion of symptoms, fever, increase of abdominal tension, ascites and ema- ciation. The number and extent of adhesions necessarily influence the course of the disease. It is surprising to note the extent of the disease at the time of operation and the favorable results which often follow. This agreeable experience may be found with complicating chronic tuberculous pericarditis and pleuritis. In the presence of nodular deposits and fibroid peritoneal thickening, it is not always easy to decide whether the process is tuberculous, a fact to which Welch, Wood and Fitz, and Henoch have called attention and deserves consideration in offering prog- noses. In these cases the peritoneum is studded with nodular growths; there are associated inflammatory exudates, usually serous, in which the prognosis is most encouraging. (c) Chronic Fibroid Tuberculous Peritonitis Surgical Treatment and Prognosis The influence of radical treatment (operative) on the prognosis of tuberculous peritonitis is of the greatest interest and importance. The study of a large clinical material has led me to the advocacy of early surgical interference in all cases of tuberculous peritonitis in which com- plications offer no contra-indications, with encouraging results—recovery in 80 per cent of such cases. The English authorities argue against operation in infants under 12 months. I number among my cases a lad now 20 years of age who was but 10 months of age at the time of opera- tion, with large multiple tubercle nodules in the abdomen, succulated serous effusion and adhesions, who has continued in perfect health and shows no lesions at present. The prognosis is unfavorable after surgical interference in the pres- ence of general and widespread tuberculosis. BACTERIAL DISEASES 261 The most favorable results follow operation for chronic tuberculosis of the peritoneum with ascites, and some surgeons are now limiting their surgical treatment of peritoneal tuberculosis to that class of cases. Schramm reports with children 80 per cent of cures among the operated and 64 per cent among non-operated cases. Pic admits recoveries among 74 per cent of the operated against only 5 per cent of the non-operated cases. Sutherland makes the startling statement that he found 50 per cent of recoveries among the operated and 81 per cent of recoveries among non-operated cases. Thus Eolleston submits the result of his experience in cases gathered from literature and practice as follows: Of 125 cases treated by operation there were 88 recoveries, 70.4 per cent; of 156 cases not operated there were 51 cures, 33 per cent. My experiences justify the conclusions that in carefully selected cases, without barring young children, basing such selection on data furnished in the preceding paragraphs of this chapter dealing with tuberculous peri- tonitis, the prognosis is enormously improved by early conservative sur- gical treatment. Further, while the disease may heal spontaneously, such incidence is not of sufficiently frequent occurrence to be depended upon in the majority of cases “spontaneous cures” are not always lasting; periods of latency are not infrequent and among spontaneous cures and latent peritoneal tuberculosis there are many recurrences, more by far than follow after operation; the dangers of dissemination are also greater among the apparently cured without operation than among those who have been helped by surgical methods. My experiences further agree very closely with those of Bandelier and Roepke that 96 per cent of untreated tuberculous peritonitides die; of these 50 per cent die in from 1 to 6 months, 25 per cent in from to 1 year; the remaining cases may live with persisting symptoms during long periods, the length of time depending on many factors previously considered. My clinical material includes but two cases in which the operation was followed within a few days by the death of the patient. In one, the patient a boy age 18 seemed to present conditions that were favor- able, his temperature had been high, the pulse rapid and small, there was abundant ascites, without evidences of distant tuberculosis in physical signs, but the acute history justified the strong suspicion of general mil- iary tuberculosis. The operation was followed by continuous hyperpy- rexia during three days and the death of the patient. There was far- reaching miliary disease. The second case was practically a repetition of the first, with prompt lethal ending within seven days. References Bandelier & Roepke. Klinik der Tuberculose, 1914. Borschke.

If found, it is in children with generalized tubercu- losis, and is without marked influence on the progress of the disease. Pitt reports one pancreas tuberculous in 2,000 autopsies and accounting for per cent “of all cases in which pancreatic disease has been noted.” Mayo and Sendler have successfully removed tuberculous masses from the pancreas or from the neighboring lymphatic glands which were pal- pable. References Mayo & Sendler. Oser, Disease of the pancreas. Amer. translation, 1903. Pitt. Allbutt & Rolleston. 2. ed., iv. part I. 10. Tuberculosis of the Spleen In all forms of disseminated tuberculosis, tuberculous deposits varying in size are found in the spleen. In some cases the capsule is more involved than the spleen itself and there may be consecutive perisplenitis and local peritonitis. Caseation of tubercle in the spleen with general tuberculosis is possible. With chronic pulmonary tuberculosis, multiple tubercles of consider- able size may be present in the spleen, causing enlargement, but no recog- nizable subjective symptoms. The tubercle grows more rapidly in the spleen than in the liver and is most likely to he found with tuberculosis of early life. There are cases of primary splenic tuberculosis which cause great en- largement of the organ, polycythemia, with positive reaction to tuberculin tests, in which splenectomy offers the only hope (over 80 per cent re- cover if operated early). Tuberculosis of the spleen should be suspected in all cases in which the organ is enlarged, and in which there is polycy- themia, without other convincing data. This combination always suggests tuberculin injection or other tests to establish an early diagnosis. The prognosis of primary tuberculosis of the spleen, if diagnosticated early, is favorable with rational surgical treatment. BACTERIAL DISEASES 263 11. Suprarenal Tuberculosis—Addison’s Disease (,Suprarenal Tuberculosis, Bronzed Skin Disease) The complex of symptoms known as Addison's disease is due to de- structive disease of the suprarenal glands; one or both are almost always tuberculous. The leading features are: increasing weakness and asthenia, pigmentation of the skin and mucous membrane of the mouth particu- larly, gastro-intestinal disturbances, increasing cachexia, small rapid pulse, low blood pressure, and marked emaciation. The tuberculous process in the suprarenals is usually bilateral and deposits in distant parts of the body are not unusual. Elsasser found in 549 cases which he studied 17 per cent with iso- lated suprarenal tuberculosis; in 43 per cent associated pulmonary tuber- culosis; in the remaining cases there were tuberculous herds in other organs. There are cases of hypernephroma associated with Addison’s complex reported by Bittorf. In 561 cases of Addison’s disease the suprarenals were normal in 12 per cent, tuberculous in 75 per cent (Levin). The description of the disease originally given by Thomas Addison in 1S55 (“On the Effects of Disease of the Supra-renal Bodies,” London, 1855) remains a classic in medical literature. Acute infection of the glands leads to a train of symptoms, without marked pigmentation, but with enormous asthenia, heart weakness, hypotension, depression, melan- cholia, at times delirium, rapid wasting of fat and muscle and death within from seven to fourteen days. The picture of extreme weakness is strik- ingly suggestive, coma or other profound nervous and toxic symptoms are soon followed by the end. In occasional cases there may be vascular changes with or without tuberculosis, thrombosis or hemorrhage into the gland substance, which are responsible for the rapidly fatal termination. Unfavorable symptoms are rapid wasting of tissues (faulty metabolism), subnormal temperature, per- sistent hypotension, diarrhea, marked blood changes, reduced hemo- globin and lowering of red blood count with marked large mononuclear lymphocytosis. Hypoglycemia, large grape sugar tolerance and adrenal- inemia are also unfavorable. Subnormal temperature followed by marked pyrexia, repeated at short intervals, are exceedingly weakening and de- pressing and presage an early termination. Eailure to produce glycosuria by the liberal injection of adrenalin with other positive symptoms must be interpreted as an unfavorable feature. Acute cases show but little or no pigmentation as a rule. The prognosis is better, so far as length of life is concerned, in pro- portion to the exent of the pigment deposit. The more chronic cases show the greatest pigmentation. Straub reports a most interesting experience with a rapidly fatal acute case of suprarenal disease in which the postmortem showed thrombosis 264 SPECIFIC INFECTIOUS DISEASES of both suprarenal veins, and in which the symptoms of Addison’s dis- ease immediately developed including, after a short period of redness of the skin, characteristic bronzing (pigmentation), asthenia, adynamia and psychic disturbance. In this case the blood pressure was but little lowered. Syphilitic deposit in the suprarenals may simulate true Addi- son’s disease and may fully recover under treatment. Many reported re- coveries were probably of syphilitic origin. In chronic suprarenal tuberculosis there may be periods of latency, remissions, long periods of extreme weakness, during which complications, ordinarily insignificant, are sufficient to cause death. I number among my histories of chronic suprarenal tuberculosis, confirmed by autopsy, one of associated pernicious anemia and another case in which there were fully developed symptoms of exophthalmic goiter. Duration.—There are cases in which, including periods of latency, the disease may continue so long as ten years. There is no stage of the disease which may not be complicated by acute exacerbations, which may in turn lead to death within a few days or weeks. In chronic cases, pigmentation may be an early symptom, preceding during long periods the usual asthenia and the pronounced nervous mani- festations of the fully developed complex. In some of these cases normal blood pressure and hyperglycemia with adrenalinemia may continue dur- ing long periods, and are favorable indications. Kraus believes that all cases, if tuberculous, finally develop characteristic symptoms and die. Typical cases run their course in from two to four years. The devel- opment of mania or melancholia is always unfavorable. Epileptiform seizures may precede coma which promptly leads to death. I have never seen recovery from coma with suprarenal disease. Kascherininowa at the instigation of von Strumpell has treated a number of cases of suprarenal tuberculosis with tuberculin, with suprisingly good results. Munro has reported similar encouraging results. There is a class of cases in which, in the last stage of the disease, symptoms resembling acute peritonitis develop from which the patient does not recover, but dies in the course of from 3 to 7 days (Ebstein). I would call the attention of those interested in the literature of suprarenal disease to the additional references at the end of this article. Bertelli, Falta & Schweeger.

Tuberculosis of Lymphatic Glands {Scrofula, Scrofulosis, King’s Evil) Cervical Lymphadenitis.—All scrofula is due to the tubercle bacillus and in a large number of cases is purely a surgical and local affection leading to tuberculous adenitis. It is found, as a rule, in children, with the “scrofulous” or “tuberculous habit.” The disease by predilection selects the glands of the neck, the bronchial nodes or the mesenteries. There is a strong tendency toward chronicity when the neck glands are involved, and toward healing, while in most superficial adenitides case- ation and suppuration is the fate of the invaded gland. Children who are “scrofulous” are vulnerable. They are “below par,” as a rule, though intellectually active. They are prone to recurring phlyctenular conjunc- tivitis and keratitis, during long periods, bone tuberculosis, ulcerative rhinitis and otitis media; they are easily influenced by climatic changes and, as a rule, are not able to endure what is usually expected of the normal child. They are also subject to skin eruptions and ulcerations with strong tendency to anemia. The skin over the involved gland breaks down read- ily and, unless the gland when caseated or suppurating is radically removed, sinuses and crusting may persist during many years. Tuberculous adenitis provides a focus from which tuberculosis may spread at any time, and it is never safe to harbor such tuberculous deposits. Bronchial Lymphadenitis.—The invasion of the bronchial nodes has been frequently mentioned in connection with the study of tuberculosis and the importance of their prognostic significance has been accented. Pressure of enlarged nodes on veins may prove complicating and cause alarming symptoms in occasional cases. In spite of the fact that tuber- culous deposit in the bronchial lymph nodes may often remain latent dur- ing many years, there is never a time when such infection is not a menace, and when from it, fatal or active tuberculosis may not be spread. My ex- periences with these nodes as provocative of rapidly spreading tuberculous meningitis have been among the saddest of my professional career. 266 SPECIFIC INFECTIOUS DISEASES Perforation of caseating or suppurating bronchial nodes may cause sud- den complications which are rapidly fatal by opening a large vein, an artery, one of the surrounding organs (esophagus, bronchus, lung or pleura), or even the heart sac. There are cases of widespread acute tuberculous lymphadenitis which resemble the acute form of Hodgkins disease. In these cases the patient wastes rapidly with high temperature (102°-106°F.), repeated chills and profuse sweating. The glandular invasion may include the lymphatics of the thorax, abdominal cavity, also the retroperitoneal space and often many superficial glands. Unless we are cautious, these cases may be mistaken for Ebstein s recurring fever of Hodgkins disease. The prog- nosis is uniformly bad, the course of the disease acute, patients die after a few weeks. With active lymphatic tuberculosis the blood changes mentioned in the general consideration of tuberculosis, including pronounced leukocytosis, are present, increased by tuberculin injection with increase of tempera- ture ; von Pirquet is positive in infected children with weak dilution. Mesenteric Tuberculosis (Tabes mesenterica).—With tabes mesen- terica there is tuberculosis of the mesenteric and retroperitoneal glands. Invasion of the glands is most frequent during early life, but there are cases of tuberculosis of the mesenteric glands in the adult, in which the infection spreads from the cecum, only occasionally from the pelvic organs or spine, and in which large masses, nodular and hard, are formed and are easily palpated. These mesenteric enlargements in the adult may remain latent during long periods, may present active symptoms early, with prompt wasting of the patient, may lead to sudden perforative peritonitis, or, with evidences of chronic peritonitis, alternating diarrhea and constipa- tion, lead to death after several weeks or months. Tabes mesenterica of childhood may be primary, but when thorough search is made it will be found that often the enlarged glands are asso- ciated with tuberculosis of one or more of the abdominal organs. The association of enlarged mesenteries with acute miliary tuberculosis, perito- neal tuberculosis, intestinal tuberculous ulceration, ileocecal invasion, is not uncommon. It may be assumed that tuberculosis of the mesenteric glands indicates infection by way of the intestines as a rule; that during early life tubercle bacilli easily wander through and beyond the intestinal mucosa without causing the slightest abnormality at the port of entry. The prognosis of all forms of mesenteric tuberculosis is bad. The pro- gressive cases are promptly associated with symptoms which do not keep the attendant in doubt; the wasting is characteristic, the increasing weak- ness with exhaustion, often diarrhea, rapid heart with small thready pulse, night sweats and fever, later added evidences of peritonitis, with or with- out ascites, are followed by death. Suppuration is not a frequent sequel. Osier calls attention as do other clinicians to the variation of the statis- BACTERIAL DISEASES 267 tics of abdominal tuberculosis in different countries and I quote the follow- ing to show these differences. “The small percentage in Hew York, less than one per cent of all cases (Bovaird and Mt. Sinai Hospital figures), contrasts with the high figure, 18 per cent for England, and the same has been demonstrated recently for Scotland by John Thomson, 3.57 for Edinburgh and 4.51 for Glasgow.” In considering the prognosis of lymphatic and intestinal tuberculosis we must once more call attention to the theory of von Behring, which is still sub judice, that the intestines ultimately serve as the foci from which pulmonary and distant infection take their origin. For the clinician who may or may not subscribe to this theory, the important fact must always remain, that in the presence of tuberculosis of the intestinal or mesenteric glands, the dangers of general infection with lung involvement are enor- mously increased.

Pathologic and clinical data accumulated during recent years have entirely revolutionized our ideas concerning the prognosis and the manner of extension of genito-urinary tuberculosis. The profession is fast becom- ing convinced that most forms of genito-urinary tuberculosis are surgical affections. In no field of medicine have the newer methods made the early local- ization of lesions more positive than in the urinary tract. I refer more particularly to cystoscopy, catheterization of the ureters, with the tests which give information concerning the funtionating ability of the sepa- rate kidneys. There are four leading facts which influence the prognosis of genito- urinary tuberculosis powerfully, well established by clinical, pathological and surgical experiences. They are: (a) The kidney is primarily affected and but one kidney is at first involved in most cases. (b) If there is positive thickening of a ureter there is coexistent dis- ease of the kidney. (c) Bladder tuberculosis is not primary; “it is merely scalded and, as such, its irritability is the sentient expression of a suffering kidney.” “This, then, is the psychological moment to interfere on the chance of cure.” (E. Harry Fenwick.) In other words, bladder tuberculosis is usually secondary. (d) Genito-urinary tuberculosis spreads downward following along the course of the infected urine “with the stream” from kidney to its pel- vis, ureter and bladder, not in the opposite direction “against the stream.” 13. Genito-urinary Tuberculosis 268 SPECIFIC INFECTIOUS DISEASES These conclusions, accepted as they are by leading urologists and pathol- ogists and by those who have worked in the field of experimental medicine, are hard to controvert. On the other hand, we cannot deny the force of clinical evidence and the results of experiments, by Wildbolz, Eckehorn and others, which do not entirely justify the exclusion of the spread of genito-urinary tuberculosis from a focus below the kidney, ascending, therefore, not often but with sufficient frequency, to conclude that deposits of tubercle in the prostate, testicle, bladder or anywhere in the tract may spread the infection. Interference with urinary drainage is the leading cause of ascending infection of the genito-urinary tract. Tuberculosis of the Kidney Potent factors which influence renal and genito-urinary tuberculosis unfavorably, are the facts, (a) that the disease may exist, make progress, advancing rapidly, without causing subjective symptoms sufficient to cre- ate a suspicion of its presence. In one of my cases a man, age 35, died suddenly without evidences of preexisting disease in symptoms; at the autopsy there was bilateral invasion of the genito-urinary tract, no rem- nant of normal kidney was found. (b) From an early stage a large part of one kidney may he involved and in occasional cases the process promptly becomes bilateral (30 per cent). (c) Changed kidney function may in occasional cases lead to grave constitutional disturbances, toxemia, etc. (d) In some cases the bladder is promptly involved in an ulcerative process, adding to the sufferings of the patient. Mixed infection also adds an element of danger which is often overcome with great difficulty. (e) In occasional cases the functional activity of the kidney is enor- mously reduced, as can be established by ureteral catheterization and functional tests; tubercle bacilli swarm in the pus-laden urine, urea is reduced, and there may be grave constitutional disturbance. Gould has called attention to the important prognostic fact that with the presence of tubercle bacilli in a urine “which contains a proper proportion of urea and is free from pus,” surgical interference is justified and, after a thor- ough search of my records and a study of the literature on this subject, I conclude that under these conditions the prognosis may be considered good. Kidney tuberculosis associated with miliary infection is without marked influence on the general course of the disease which even without the added kidney complication leads to death within a limited time. The type of kidney tuberculosis which the clinician usually meets is the caseating and ulcerative form in which the first evidences of existing disease are referable to the pelvis of the kidney and are established by urinary examination. The symptoms are those of pyelitis. To reach safe BACTERIAL DISEASES 269 and early conclusions for diagnosis and prognosis every case of pyelitis in which no positive pathologic cause can he established at once, should create a strong suspicion of renal tuberculosis, and the case kept under observation until this conclusion is corroborated or upset by scientific investigation. Early hematuriawithout other leading symptoms, is often favorable, for it creates in active adults during the years of sexual activity (when genito-urinary tuberculosis is most frequent) the first suspicion of exist- ing tuberculosis, making prompt treatment possible and cure likely. It is a primary symptom in 6 per cent of all cases and is present in 60 per cent during the existence of the disease, oftener in men than in women (Braasch). The presence of bladder invasion does not argue against the possi- bility of complete recovery. Unexplained bladder irritation must always lead to the suspicion of kidney tuberculosis; it is present in 86 per cent of all cases (Braasch). Its significance, recognized early, will do much to reduce the mortality and improve the prognosis of genito-urinary tuberculosis. Spontaneous cure or surgical removal of the primary focus in the kidney, Avhen the disease is not widespread, as a rule results in the cicatrization or cure of vesical tuberculosis. When kidney tuberculosis is limited to one organ, the bladder and lower end of the corresponding ureter are uninvolved; there are but few or no constitutional disturbances; early recognition and treatment lead to cure in the majority of cases. The most important question which interests the clinician is: Is the disease limited to one kidney? In 30 per cent of cases the disease is bi-lateral early. It occasionally happens that the disease is active in one kidney and that a small latent deposit exists in the opposite kidney which escapes detection. With modern methods of diagnosis the chances of diagnostic failure are enormously reduced, though they will occur. I have seen cases with advanced tuberculosis in one kidney and but slight evidences of disease in the opposite organ, in which the removal of the active focus led to latency and to years of comfort, and occasionally to apparent cure. Perinephric abscess of tuberculous origin, caused probably through lymphatic invasion rather than perforation of the capsule of the infected kidney, may be an early complication of limited renal tuberculosis; its prognosis is not unfavorable, if the primary focus can be radically treated. Kidney tuberculosis of limited extent under favorable surroundings may occasionally undergo spontaneous cure; if this possibility suffices for the basis of treatment, the majority of genito-urinary tuberculoses will promptly follow their natural tendency toward progression and death. With advanced pulmonary tuberculosis and disseminated genitouri- 270 SPECIFIC INFECTIOUS DISEASES nary tuberculosis the prognosis is absolutely bad. In 6 to 10 per cent of genito-urinary tuberculosis there is lung involvement. Limited lung infection does not argue against the radical treatment of renal tuber- culosis ; many such cases recover. The conclusions given by Braasch who has scientifically studied the material at the Mayo Clinic, in his “Obser- vations of 203 Patients Operated for Penal Tuberculosis,” may be ac- cepted as expressing the most advanced ideas concerning the prognosis and the incidence of the disease. Of the 203 patients operated, 6 died— 2.9 per cent. Seventy per cent of the patients were followed during a sufficient time to allow profitable conclusions. Eighteen per cent were dead; of these 60 per cent died before the end of the first year, and 15 per cent lived more than 3 years. Of the 82 per cent alive, all but 13 per cent reported improvement or recovery from their bladder symptoms; their weight and strength had increased materially. Five patients had double infections; all of these died within one year of the operation. Braasch concludes that 15 per cent of renal tuberculosis is curable by the modern methods of treatment, while 90 per cent is fatal without it. Loss of weight and strength in young subjects with fever and bladder ulceration presents an unfavorable outlook. In 60 per cent of the Braasch cases of renal tuberculosis in the male, there was deposit either in the epididymis, the testicle, vas deferens or prostate, oftener in the epididymis. I have occasionally found that an inflammatory deposit left by gonor- rheal epididymitis became tuberculous; the prognosis of such cases is good. In one-third of all renal tuberculosis in the male the prostate is also invaded. General infection may be present with renal tubercu- losis and recovery may follow. The prognosis is less favorable when the kidney deposit with breakdown of tissue has advanced sufficient to make the organ palpable. Kidney tumor is present in from 20 to 25 per cent of cases. Persistent fever with symptoms of genito-urinary tuberculosis and rapid small pulse, with increasing anemia and loss of weight are all unfavorable. Besides the convincing statistics of Braasch to encourage the early recognition of genito-urinary, more particularly, renal tuberculosis, we find Bandelier and Boepke average recoveries after radical treatment at 50 per cent, Israel 63 per cent and Caspar reports 67 cases with 50 cures. Pregnancy and. childbirth usually stimulate renal and genito-urinary tuberculosis to renewed activity. Israel has demonstrated the evil effects of pregnancy in a large number of cases on existing renal tuberculosis. In almost all of these cases rational surgical treatment has proved effi- cacious. Blood Pressure.—As in all forms of tuberculosis, so with advanced genito-urinary involvement and kidney degeneration, the systolic blood BACTERIAL DISEASES 271 pressure will be found below normal; decided hypotension is unfavorable and is usually found with a small and rapid pulse, disseminated disease, and advanced ulceration in the terminal stage of the disease. Progres- sive fall of blood pressure with loss of weight is always unfavorable. Failure to improve the circulatory condition by operation is also ominous. The dangers of secondary invasion of the meninges, lung, intestines, peri- toneum and bone, and the possibility of rapidly advancing amyloid degen- eration are not to he ignored in prognosis.

Genital Tuberculosis in the Female Menstrual Irregularities.—In the female we find with tuberculosis, menstrual irregularities which are usually associated with chlorotic and anemic conditions. The most frequent anomaly is amenorrhea, which is often an expres- sion of reduced vitality and may yield as the general condition of the patient is lifted and the blood picture is improved. Amenorrhea with in- cipient pulmonary tuberculosis without evidences of toxemia or advanced lung change, with chlor-anemia, almost always disappears under favorable surroundings unless the disease is progressive. There is in some cases, when advanced, atrophy of the uterus to which the amenorrhea has been attributed by Thorn and others. Serious .tuberculous diseases of the genital tract in women lead to anemia, particularly when there has been profuse hemorrhage or suppuration; under such conditions there may be amenorrhea or other menstrual irregularities. The Blood.—The blood condition offers valuable data for prognosis with genital tuberculosis or menstrual anomalies. The following blood picture may be considered unfavorable in the presence of genital tuberculosis: (a) Marked reduction of erythrocytes and morphologic change. 272 SPECIFIC INFECTIOUS DISEASES (b) Reduced hemoglobin. (c) Lymphocytosis (34 per cent). Excess of small mononuclear cells. (d) Prominence of Arenth picture. Displacement to left. Can Tuberculosis Be Primary in the Female Genital Tract?—Amann makes the unqualified statement that there is no 'primary tuberculosis of the genital tract in women. Eor our purposes as prognosticians, there are a number of facts which contradict this dictum, though we must admit its truth in the majority of cases. Schlimpert is a warm advocate of Amann’s contention. The former claims that tuberculoses of the genitals are in 80 per cent of pulmonary origin, in 50 per cent they are secondary to intestinal tuberculosis, and that bone and lymphatic tuberculosis supply the foci for the remaining cases. The tuberculous diseases of the genitals in women are found in the I. Fallopian Tubes II. Ovaries III. Uterus IV. V agina. When of long duration, the disease is disseminated. I. Fallopian Tubes.—Kermauner claims that the Fallopian tubes are involved in from 70-90 per cent of all genito-urinary tuberculosis in women, the uterus in 40-65 per cent and the vagina in 10 per cent. The most patient search in many cases of tubal tuberculosis, fails at the time of the operation to show any other focus, and the large per cent of com- plete and lasting cures following, argues very strongly against the assump- tion that these are all of secondary origin. Naturally, the earlier tubal tuberculosis) is recognized the better is the prognosis, for the changes are prompt and may progress without subjective symptoms. Thickening of the tubes with caseation, the formation of creamy and cheesy tubercle bacilli-laden pus, and adhesions are characteristic, and from this focus general peritoneal tuberculosis may advance, or may be aggravated if already existent. In over 50 per cent of tuberculous peritonitides there is coexistent disease of the Fallopian tubes and, ovaries. II. Ovarian tuberculosis is as a rule secondary and is not infre- quent: usually the uterus and a Fallopian tube or the latter and the ovary are involved. Perioophoritis is a part of tuberculous peritonitis. The ovarian disease is usually double; one ovary may be more involved than the other. The disease advances in the ovary without materially inter- fering with the general condition of the patient in chronic cases, with the deposit of either multiple small foci or one or more large cheesy deposits. Tuberculous salpingitis may be far advanced without ovarian involvement. Ovarian and tubal infection often follow latent, unrecog- nized, or active general or localized peritoneal tuberculosis. Unrecog- BACTERIAL DISEASES 273 nizcd pulmonary deposit, or a tuberculous focus in some distant organ, may through the blood stream lead to genital infection. III. The Uterus.—When the uterus is tuberculous, the disease is usu- ally advanced in the tubes, in the ovaries, and there are likely to he evidences of adhesive tuberculous peritonitis, matting the pelvic organs together by dense adhesions. TJterine tuberculosis leads to cheesy degen- eration of the endometrium, which, if neglected, finally invades the mus- culature, limiting itself as a rule to the corpus uteri. In some cases the patient’s condition is reduced by the continuous discharge due to an ac- companying tuberculous endometritis. (Pyometra tuberculosa.) In considering the direction in which genital tuberculosis spreads (an important prognostic element), it will be found that extension is descend- ing under average conditions, rarely ascending. Baumgarten believes as the result of experimentation that in women the spread of tuberculosis is always in the direction of the wandering of the ovum, while in man the flow of the spermatic fluid marks the direction in which the disease spreads from, a primary focus. The unqualified acceptance of this theory is not justified; it unquestionably has exceptions which must be considered by the clinician. Direct infection of the genitalia in women from without is possible; bacilli may be introduced with the spermatic fluid or in other mechanical ways. IV. The Vagina.—Vaginal ulcers of tuberculous origin may be pri- mary and yield to radical treatment. In advanced genital tuberculosis there may be marked change in the vaginal wall, which, barring the dis- comfort and pain, does not materially influence the prognosis of the exist- ing primary disease. It is surprising to note how favorably even ad- vanced genital tuberculosis with vaginal invasion is often influenced by thorough treatment. In all forms of genital tuberculosis there is a strong tendency to the formation of protective adhesions; nature seeks to hold the disease within narrow limits. It occasionally happens that for some unknown reason general miliary tuberculosis promptly follows the removal by operation of tuberculous genitalia; this is a rare sequel. Generally speaking, it may be said that the prognosis of the genital tuberculosis of women is good; that the larger number of cases are ac- cidentally discovered in tubes, ovaries and uterus, though often strongly suspected, that in accordance with modern pathologic views “genital tuber- culosis in the male and in the female is not dependent for its origin upon urinary tuberculosis.” The safest conclusion for the practical physician to reach is that in the larger proportion of cases genital tuberculosis is secondary to a focus for which search should be made, but which may not be found; that the prognosis is so uniformly favorable in such a 274 SPECIFIC INFECTIOUS DISEASES large number of cases that, in at least a number of these, primary infec- tion must be acknowledged. The coexistence of urinary and genital tuberculosis in both male and female does not of necessity lead to death; there are many cases wdiich are favorably influenced by surgical and medical treatment, while in some there may be spontaneous cure, or long periods of latency are established. Without an appreciation of the dangers of coexisting genital and urinary tuberculosis and rigorous treatment to establish resistance, the prognosis is grave. References Amann. Internal.

Cardiovascular Tuberculosis Reference lias frequently been made to the heart, its small size, the involvement of the myocardium, and to the possibility of spreading miliary tuberculosis from the infected blood vessels, and the prognostic significance of cardio-vascular invasion. The statistics of Weigert proved 50 per cent of all miliary tuberculosis traceable directly to vascular tuberculosis, while to-day statistics (Schmorl, Lubarsch, Benda) prove 95 per cent of all miliary tuberculosis to be dependent upon this method of dissemination. Hence, every local tuberculous herd, closely related to an artery, vein, or thoracic duct, or the lymphatic stream, remains an element of danger. Vascular tuberculosis or infection represents there- fore, the link between the primary focus and miliary tuberculosis, a dictum of enormous prophylactic and prognostic value. Tuberculosis of the Aorta.—Tuberculosis of the aorta and other vessels may develop and lead to death. In these cases bacteria “penetrate the inner lining of vessels from the main channel,” in the presence of a forcible blood current, causing inflammatory change of the intima and secondary thrombosis. (Flexner, Blumer, Stroebe, Aschoff, Schmorl, Krumbhaar, Hekton). Tuberculous Pericarditis.—Tuberculous pericarditis is rarely pri- mary; it is usually part of a widespread process (pleural, pulmonary, lymphatic) which may run a chronic or an acute course. In chronic cases adhesive pericarditis may lead to stasis, edema, dyspnea, anginoid attacks, evidences of abdominal dropsy with enlarged liver and spleen, and cya- nosed kidney. BACTERIAL DISEASES 275 The acute cases often lead to hydropericardium, which may he hemor- rhagic with preponderance of lymphocytes (50 per cent and more) in the fluid. While the prognosis of tuberculous pericariditis is supposed to be unfavorable, we have found in practice that occasionally latency and cure may follow, and that, with disseminated tuberculosis, peritoneal and pleural, with but little or no lung invasion, cases have been cured by radical surgical interferences. We number among our medical colleagues one such fortunate case in which there was widespread tuberculosis of the pleura, peritoneum and pericardium, in which after eleven opera- tions, including one pericardial resection (cardiolysis of Brauer) and relief of adhesions thereby, there is now complete recovery, with suffi- cient, strength for the patient to resume practice. Romberg reports 16 cases of tuberculous pericarditis of which only four died, while 4 of his 10 idiopathic pericarditides died. Myocardium.—With miliary tuberculosis there may be deposits in the myocardium; these offer no symptoms which prove their pres- ence, and as Romberg has said, “interest the pathologist more than the clinician.” The change which is almost constant with tuberculosis is fatty degen- eration of the myocardium Avith marked anemia in the terminal stage of the disease. Tuberculous deposits in the myocardium in chronic phthisis are exceedingly rare. Willigk found but two hearts in which there was tuberculous deposit in 1,845 tuberculous subjects autopsied by him. Endocarditis.—Endocarditis of purely tuberculous origin is also rare. Occasionally there are a few vegetations on the endocardium with charac- teristic histologic build. But, as Marshall has demonstrated, the incident is not of sufficient frequency to justify the suspicion of its presence; on the other hand, when present, no symptoms make its recognition positive. Michaelis and Blum have proved the possibility of producing tuberculous endocarditis experimentally. Rot all valvular lesions found in the tuberculous subject are due to the tubercle bacillus. Many.of these lesions are old and of rheumatic (strepto- coccus rheumaticus) origin. In early life endocarditis tuberculosa may develop with general miliary tuberculosis. All of these children die. In the adult, endocarditis due to streptococcus infection may complicate tuberculosis or there may be chronic ulcerative endocarditis Avith tuberculosis, in which the Streptococ- cus viridans has proved to be the pathogenic factor. This complication may hasten the progress of the primary disease, but runs a chronic course, being the cause of most chronic malignant endocarditis. Klebs has also reported acute mycotic endocarditis Avith tuberculous phthisis. Thrombosis.—The formation of heart clots, thrombi in the pulmo- nary artery or veins of the body—ante mortem—in tuberculous sub- 276 SPECIFIC INFECTIOUS DISEASES jects, is a cause of death which was recognized by Rokitansky, Klebs, Birch-Hirschfeld, Weichselbaum and others. In these cases, depending on the location and extent, there may be gradually increasing symptoms during several days or death may be sudden. Peripheral venous throm- bosis in the terminal stages of phthisis is frequent. Dodwell found the proportion of cases with this complication to be about 3 per cent. These peripheral thromboses are found in the terminal stages of the disease, when the circulation has become insufficient. Constriction of Veins.—Constriction of veins—one or more—by new connective tissue, causing blowing systolic murmurs in various parts of the lung, may appear alarming to the inexperienced; as a rule, they add but little to existing dangers. Pulse.—Changes in frequency and rhythm of the pulse often offer valuable prognostic data. The tachycardia of the end stage, during which the pulse may reach 200 per minute, is always of great prognostic impor- tance; with such a pulse, sudden cyanosis and death may follow. The Heart.—Whatever conclusions we reach concerning the size of the heart in the tuberculous subject, we must admit that Brehmer’s con- tentions (that the heart is undersized; that unless aided by proper methods it sends insufficient blood to the lung; that, as the direct result of its congenital fault, it is largely responsible for the development of pulmonary tuberculosis) have, with the impetus received by the approval of Dett- weiler, lead to the most rational and successful therapy of tuberculosis, the basis of which is the improvement of the tone of the insufficient heart, and all muscles, and the upbuilding of the patient. The theory of Rokitansky already mentioned in the general consideration of tuberculosis, that heart lesions antagonize pulmonary tuberculosis, particularly those which pro- duced venous stasis (initial lesions particularly) has been considerably shaken during the past fifty years. Fromholz found in 7870 autopsies, 277 valvular lesions (3.5 per cent) of which 22 (8 per cent) had pul- monary tuberculosis. With but one exception these were associated with disease of the left heart. Mitral stenosis certainly antagonizes the develop- ment of tuberculosis of the lung as does mitral insufficiency with marked pulmonary engorgement and brown induration of the lungs. Blood Pressure.—I have already referred to the behavior of the blood pressure in pulmonary tuberculosis. Its progressive fall with small pulse is always unfavorable. Rise of blood pressure with even slight gain of weight is favorable, for it is suggestive of control of the process. Aschoff. Verhandl. d. Deutsch. path. Gesel., 1899. Bturner.

Tuberculosis of the Nervous System Tuberculous Meningitis.—The prognosis of tuberculous meningitis is considered in connection with miliary tuberculosis. (See Miliary Tuberculosis.) Single tubercle nodules may exist in the brain without giv- ing rise to symptoms or there may be positive evidences in symptoms of tumor of the brain. In another class of cases there may be sufficient im- provement to justify the conclusion that the patient has made a fair recovery; periods of latency are not unusual, followed by sudden exacerba- tion and death; or spontaneous cure due to encapsulation or calcification, if the masses are small, may be followed by entire freedom from symptoms. Spinal meningitis, leptomeningitis, of primary origin is so rare as not to require consideration. When the pia is invaded, it is part of a dissemi- nated process, whether miliary, i. e., multiple deposit, or single large cheesy tubercle, with possible involvement of the cord, i. e., tuberculous myelitis, which offers no chance for restitution. Tuberculous pachymeningitis is also secondary, as a rule to bone tuber- culosis, the extent and its seriousness varying in accordance with the under- lying cause; usually the process ends in death, though life may be pro- longed and the disease remain stationary. There are but T4 authentic cases of spinal tuberculous pachymeningitis in medical literature (Bande- lier and Roepke). Myelitis.—Evidences of jnyelitis in a tuberculous subject must always strengthen the diagnosis of pressure due to bone disease or secondary de- posit in the membranes; in both the symptoms are those of compression and the prognosis is bad. The prognosis is better in those cases of tuberculous compression mye- litis due to caries or other bone change in which there has been ossification with latency. In these cases the mischief done cannot be overcome, but 278 SPECIFIC INFECTIOUS DISEASES the process in the cord due to pressure does not advance and there may be slight improvement of the myelitic symptoms. Extra-medullary tubercle nodules causing compression myelitis, may, if single, be removed without causing destruction of cord substance and restoration of function may follow. Naturally the prognosis, so far as the life of the patient is con- cerned, must depend on the extent of the primary disease. It is surprising to note how superficial these nodules are often placed and how easily they may be removed. Neuritis.—There are occasionally cases of neuritis (peripheral) in tuberculous subjects, which, when a single nerve is involved, frequently yield to treatment, with full restoration of function. When there is limited compression neuritis, and the mass, which may be an enlarged gland or tuberculous bone, can be removed, the prognosis is also good. If in such cases there are multiple glandular enlargements at the same time, the advance of the process depends on many factors previously considered; the outlook is not encouraging, though the single neuritis may have been overcome. Multiple neuritis (polyneuritis) of tuberculous origin offers a less favorable prognosis than does single neuritis. It is often a terminal com- plication with cachexia. In alcoholics it may yield to treatment and dis- appears ; it is then non-tuberculous but alcoholic. Invasion of the cranial nerves is one of the early evidences of tubercu- lous meningitis as a rule, and offers a bad prognosis. (See Tuberculous Meningitis.) If there is early involvement of the pneumogastric or phrenic, death follows promptly. In children the majority of lesions (paralyses) referable to the cranial nerves are secondary to tuberculous basilar deposits; the correct diagnosis and prognosis need not be long postponed.

XXL Rheumatic Fever (Acute Polyarthritis, Inflammatory Rheumatism, Rheumatic Fever) Acute polyarthritis is an infectious disease in all probability due to the Streptococcus rheumaticus (Poynton and Paine and Rosenow) charac- terized by constitutional disturbances, inflammatory swelling of several joints in most cases, though the disease may be monarthritic. There is always great tendency to inflammatory changes in the serous structures of the joints involved and in over 50 per cent of all cases there is accompany- ing endocarditis. BACTERIAL DISEASES 279 The disease tends to relapse; following one attack during several years there is great tendency to recurrence. The disease is most frequent during the winter months (January, February and March) and during this season is likely to be more severe and its duration longer than during the warmer season, though there are many exceptions to this statement. Bacteriology The study of the bacteriology of acute rheumatism has not led to posi- tive conclusions until recently, when the observations of Poynton and Paine were confirmed by Rosenow. Poynton and Paine make a strong plea for the acceptance by the profession of their contentions, made dur- ing the past few years, that the Diplococcus rheumaticus is the specific microorganism upon which they claim the disease depends. The bacteriology of acute arthritis has received the attention of many pathologists and clinicians, including Leube, Leyden, F. Meyer, Glaser, Menzer, Sahli, Kraus, Schottmiiller, Jochmann, Litten and Lenhartz (See References), without results which to the minds of these observers justified the conclusion that the specific organism has been discovered. We feel safe in concluding, however, that the proofs offered by Poynton and Paine as well as Rosenow justify the conclusion that polyarthritis' is an infec- tious disease and is in all likelihood due to the streptococcus rheumaticus. Rosenow says: “The name streptococcus rheumaticus may be retained at present, not with the idea that organisms so-called always produce rheu- matism, but rather to call attention to the fact that when streptococci pro- duce the symptoms and lesions of rheumatism they have certain special features which streptococci from other sources do not usually have.” Mortality Rheumatic fever does not offer a serious prognosis. The mortality of all cases may be safely accepted as being between 3.Y per cent and 4.5 per cent. Hoffman found in his analysis of the cases at Johns Hopkins from 1892 to 1911 that the mortality in YO males was 4.3 per cent without a death among the 15 females reported. There are many factors which influence the course of the disease and its severity; the study of its prognosis may be divided into the considera- tion of: Factors Influencing Prognosis I. The resistance of the patient. II. The sex and age of the patient. III. The character of the onset. 280 SPECIFIC INFECTIOUS DISEASES IV. The nature of chronic preexisting and acute coincident disease. V. Complications. (a) Heart. (b) Hyperpyrexia. (c) Brain and Nervous System. (d) Blood. (e) Lung and Pleura. (f) Kidney. (g) Peritoneum and Appendix. (h) Skin. (i) Rheumatic nodules (Meynet). (j) Septic Conditions. (k) Purpura. VI. Duration. VII. Environment and Social Conditions. VIII. Relapse. IX. Immunity. I. Resistance of Patient As in all acute infections, those reduced in health, the weak, the obese, the alcoholic, and the dissipated, those who have been exposed to the elements without protection, those who work in damp places away from the sunlight and those who seem to be predisposed by heredity, present a lowered resistance, contract the disease after even slight exposure and are more likely than are those without these unfavorable factors to suffer from the severer forms and its complications. Poynton has called atten- tion to the influence of heredity in fragile children, “particularly if this be derived from both parents.” Such subjects are liable to destructive forms of carditis, to “deadly persistence of the process with increasing anemia, and not infrequently the development of nodules.” There is a greater likelihood of chorea during early life. In children the effect of chorea with severe carditis is always ominous and demands a guarded prognosis. We will again refer to the influence of age in con- nection with the consideration of the complications. II. Sex and Age Sex is not an important factor in prognosis; men contract the disease oftener than women because they are more exposed. The report of Whip- ham showed among 654 cases, 375 males and 279 females. In our prac- tice the proportion of females to males is 1 to 3; the same proportion is shown in our hospital service. Eemales in our service have suffered the same complications as men, without material differences in the prognosis. Between the ages of ten and twenty the proportion of female patients predominates. Kemp found at the Radcliffe Infirmary in Oxford that BACTERIAL DISEASES 281 between the tenth and nineteenth year there were among 49 cases 18 males and 31 females, or 47.1 per cent of all of the cases reported. The figures of Church showed 43.5 per cent of 943 cases between the same ages. Age.—In children, the complications, particularly those involving the heart, are more frequent and more serious than in the adult; the disease is not frequent) before the sixth year. In young children, pericarditis is always a source of great anxiety and endocarditis is likely to leave per- manent valvular lesions. Langmead reports the “incidence of arthritis in children very high.” He examined 2,556 children, of which 133 were rheumatic and in all but 18 the heart was involved. “In 43 per cent of these cases there was some abnormality of the tonsils or pharyngeal mucosa.” Whipham reports that of the cases considered, 32 cases were under ten years of age and 80 per cent were between twenty and forty years of age. III. The Character of the Onset It is difficult to offer a forecast from the consideration of the method of onset of the disease. There are cases which begin without prodromata hut with sudden high fever and multiple arthritis in which the course is short and com- plications are few; while, often, cases which begin insidiously without fiery symptoms, with gradually increasing joint invasions, run a pro- tracted course, including serious complications. There are cases which begin with high fever, promptly develop hyper- pyrexia with well-pronounced cerebral manifestations, usually the ear- marks of meningitis; at first there is a full pulse, in which the course is foudroyant; death results within the first two to four days. These resemble the cerebral rheumatism of the older writers. Persistently rapid pulse during the early days of the disease with or without high fever must claim the close attention of the attendant, for it may signify myocarditis or some other early and serious complication. Early arhythmia, intermittence or irregularity of the heart, with evi- dences of myocardial weakness or dilatation, influence prognosis unfavor- ably, both in children and in the adult. Early profuse sweating, unless accompanied with heart lesions or other depressing complications, is not unfavorable. Cold extremities, small, rapid pulse with profuse sweating early, is an unfavorable combination. IV. The Nature of Chronic Preexisting or Acute Coincident Disease Preexisting1 Diseases.—Preexisting diseases, particularly those which are depressing, reduce the blood state, cause heart weakness or mental depression, always lower the resistance of the arthritic. 282 SPECIFIC INFECTIOUS DISEASES One of the most important factors in the prognosis of rheumatism is the condition of the heart 'previous to the acute attack. Chronic valvular disease always increases the dangers of arthritis; the nature and extent of the preexisting lesion is important. Preexisting pleurisy, and myocarditis add to the dangers of acute polyarthritis. When arthritis develops in a nephritic, the prognosis must necessarily depend upon the stage of the nephritis, its character and the complica- tions. If there is chronic uremia, the added rheumatism will have an unfavorable influence. With preceding acide nephritis following acute infections and added arthritis, the prognosis may continue to he grave and uncertain during varying periods. Diabetes with acute arthritis superadded, is at times complicated by suddenly arising acetonemia and presents a serious prognosis. With most chronic diseases which complicate acute arthritis, the prog- nosis must depend upon the associated symptoms and added complica- tions. As a rule, the arthritis runs a favorable course and leaves the patient in his previous condition after a reasonable period of con- valescence. The addition of arthritis to chronic tuberculosis is considered in con- nection with the latter subject. (See Tuberculosis.) Acute Coincident Diseases.—Among the acute coincident diseases with which arthritis is found are tonsillitis, typhoid fever, typhus, scarlet fever, erysipelas, diphtheria (serum sickness), mixed infections and a variety of less frequently arising infections. Tonsillitis or tonsillar infection of some kind is present in from 70 to 80 per cent of all acute arthritides. Tonsillitis or tonsillar infection, the pathogenic factor of most arthritides, does not influence prognosis unfavorably if the clinician appreciates its significance. Typhoid and typhus fever with rheumatism are, as a rule, but slightly influenced by the latter disease, for if is likely to be a late complication and in our experience has not often been severe. In children, following closely after typhoid or associated with it, there is greater danger of heart complication and the prognosis is therefore relatively worse. Arthritis with scarlet fever offers a good prognosis so far as life is concerned. In over 90 per cent of cases there is great danger of endo- carditis, nephritis and occasionally pericarditis, which necessarily influ- ence the course of the disease unfavorably and permanent damage to valves often results, while convalescence may be long postponed and relapse of the arthritis is not uncommon. Erysipelas with arthritis may be either suppurative or non-suppu- rative. When suppurative, the evidences of sepsis or pyemia are sufficient to warrant a guarded prognosis. These cases are always serious. Septic BACTERIAL DISEASES 283 thrombosis with such complications are to be feared. The nonsuppura- tive arthritides with erysipelas lead to recovery unless the latter disease is an expression of profound sepsis or both are complicated by serious heart, kidney or brain lesions. Diphtheria. Serum sickness following the use of antitoxin, with joint swellings and other evidences of arthritis, is of short duration and patients recover. Acute arthritis with diphtheria is less frequent than with scarlet fever; all of our cases have recovered. There may be sequeke including damaged endocardium or nephritis. The presence of arthritis does not in any way influence the incidence of post diphtheritic paralysis. Mixed Infections.—Mixed infections are always serious. Strepto- coccus or staphylococcus infections are often associated with malignant and septic endocarditis, nephritis, infarcts and justify an unfavorable prognosis. We will refer fully to malignant endocarditis in another chapter. (See Malignant Endocarditis.) The malignant rheumatic endo- carditis of Lenhartz and Litten is also considered with Malignant Endo- carditis. V. Complications (a) Heart.—Endocarditis. . In the adult there is complicating endo- carditis in 34.3 per cent (Pribram) ; in children the percentage is between 60 and 80 per cent of polyarthritides, varying during different years and seasons. Arthritis is the most frequent cause of acute endocarditis and there- fore of chronic valvular defects. Bouillard in 1836 made the statement that “with severe and generalized rheumatism, endocarditis is the coinci- dence, pericarditis or endopericarditis the rule, absence of the lafter the exception. . . . With acute rheumatism which is mild, afebrile, partial, endocarditis is not the coincidence, and the coincidence of pericarditis or endopericarditis is the exception.’'1 The prognosis of endocarditis in childhood is less favorable than in the adult. In the adult the majority of endocarditides complicating arthritis make recoveries with hut insignificant valvular damage. The larger number of lesions are finally found to change the mitral valve more than any other and the heart soon compensates for the fault. In both children and adults hut few who have relapses escape endocardial infections. Stephen MacKenzie’s statistics quoted by Osier show that of 116 cases, 58.1 per cent had endocarditis in their first attack, 63 per cent in the second attack, and 71 per cent in the third attack. In children the acute manifestations of the complication may, during many days, cause great anxiety and make the prognosis uncertain. When endocarditis and pericarditis are coincident in the child, or in the adult, the danger is greatly increased, always more in the child. 284 SPECIFIC INFECTIOUS DISEASES Malignant endocarditis at all ages offers the same unfavorable prog- nosis (see Malignant Endocarditis) ; it is not frequent with the usual rheumatic infection, but when there is mixed infection, streptococcus or Streptococcus viridans, there is likelihood of endocardial infection. With Streptococcus viridans and pneumococcus endocarditis following or accom- panying arthritis, the course is likely to be chronic, particularly with the viridans infection; the outcome is always fatal. Severe endocarditis in children with chorea and rheumatism is among the most painful of all combinations, and justifies only the most guarded prognosis. In children as in adults many cases of acute arthritis with dilated hearts or slight mitral lesion make prompt recoveries and it is not at all unusual to find that the physical signs of endocarditis disappear and subjective symptoms may never recur. With mild grades of endocarditis in children and chorea, recovery is the rule. If, in these, endocarditis leads to mitral stenosis, as it some- times does in the more chronic cases, the outlook is more serious than without it. If with mitral stenosis in children and adults there are repeated relapses and fresh endocarditis is grafted on the old, the prog- nosis becomes correspondingly worse. It may be positively asserted that with a remnant of endocarditis shown'by positive physical signs in adults and in children the prognosis becomes worse with each relapse of arthritis; with these cases, as Povnton has said, “the prognosis, apart from this unknown factor (recurrence), turns mainly upon the condition of the heart.” Poynton’s conclusions concerning the significance of valvular lesions in children are applicable to the adult as well and they are here quoted: “(1) Mitral incompetence, if slight and well compensated, gives a favorable outlook. “(2) Mitral incompetence with a large feeble heart and symptoms of breathlessness and asystole is gloomy; such cases run a very unfavorable course in childhood. “(3) Slight mitral stenosis is compatible with a long and useful life. “(4) Progressive and severe mitral stenosis in childhood gives a very grave outlook for the future. “(5) Aortic and mitral disease combined are very serious when the aortic lesion is well marked; when this is only slight the cases fall into line with those of simple mitral incompetence. “(6) Primary aortic disease of severity is rare, but the outlook is grave.” It is often surprising to note how desperately ill patients may be with endocarditis complicating polyarthritis, how feeble the pulse and threatening the objective signs and how they may rally to make slow but satisfactory recoveries. BACTERIAL DISEASES 285 Pericarditis.—Pericarditis complicates from 5 to 6 per cent of adult rheumatism and from 10 to 20 per cent of the cases during childhood. There is, in the majority of severe cases, coincident endocarditis and often characteristic changes in the myocardium, to which we will refer in this chapter. During early life the prognosis of pericarditis, whether serous or purulent, is less favorable than in the adult. In very young children pericarditis is likely to prove a fatal complication. In children, peri- carditis with recurring attacks, in which there is a preexisting endocardial lesion, proves exceedingly grave. Poynton’s experience has been repeat- edly confirmed, i. e., that in children, “practically all the fatal first attacks develop pericarditis.” With asystole, adherent pericardium and hyper- trophy of the heart, the prognosis is unfavorable in children; in adults, these conditions are also exceedingly grave. In both children and adults the majority of serous pericarditides make satisfactory recoveries, though the associated endocarditis may and often does lead to valvular deformity. It is never to be lightly regarded. In the adult, and in the child, pericarditis is associated with myo- cardial change in many cases, which has a strong influence on prognosis. Suddenly arising or gradually increasing heart weakness with peri- carditis, from whatever cause, clouds the forecast; in most cases it leads to death unless promptly overcome. It will always be wise to give a guarded prognosis in cases which recover as to the future of the heart, for slowly forming adhesions may interfere with the functioning ability of the heart and lead to irre- parable cardiac asthenia. Myocarditis.—Thrombo-myo-endocarditis.—The myocardium is the most important organ for prognosis in arthritis, as in all acute infections. Myocarditis is present in 15 per cent of all cases. It may be assumed that with an unchanged myocardium and the absence of vasomotor paralysis, the prognosis of polyarthritis is favorable; icith a changed myocardium the prognosis remains uncertain. Severe rheumatism with endocarditis is usually associated with changes in the myocardium which are characteristic, differing from those found with other infections. Aschoff and Tawara described this peculiar myocar- ditis of polyarthritis. It consists in a leukocytic infiltration of the myo- cardium ; there are foci of large round cells, mononuclear with basophilic colored protoplasm; there is a unique wreath-form arrangement of the cells. These foci are found in the perivascular connective tissue, they are subendocardial, there is thrombus formation near the surface, pro- ducing the thrombo-endocarditis of Aschoff. Poynton and Paine pro- duced this type of thrombo-myo-endocarditis experimentally with the germ which they claim to be the specific organism of polyarthritis (Diplococcus rheumaticus). 286 SPECIFIC INFECTIOUS DISEASES In cases of, moderate severity without marked symptoms referable to the myocardium, it is often difficult to tell the depth of the change in the muscle. Subsequent histories prove that unrecognized myocarditis leads to dilatation and faulty function during many months and with added interstitial change may cause permanent damage or death. Most cases of myocardial weakness without valvular lesions in children and in adults eventually lead to recovery. Many systolic murmurs heard during acute polyarthritis are due to myocardial change and are not of endocardial origin. Ventricular dilatation due to myocardial weakness may cause these and they usually disappear as the relative insufficiency is relieved. The strength of the myocardium or the “heart’s working capacity” is best tested by learning, as Kemp has claimed, the “amount of physical 'work which each individual can do in earning his or her living.” This natu- rally requires a full consideration of the individual case after the period of convalescence. Sudden Death.—Sudden death is not frequent. As a rule it is due to myocarditis, thrombosis or embolism. With hyperpyrexia death may be sudden. We have seen such patients die within a few minutes after convulsions. Blood Pressure.—At the height of the attack blood pressure is usually low; in the average adult and moderately severe polyarthritis it averages 100 mm. Ilg. Hypotensive conditions which increase or persist influence prognosis unfavorably. With marked myocarditis rheumatica (Aschoff type) the prognostic conclusions will be materially strengthened by the intensive study of blood pressure. High blood pressure early, with tense pulse and previous nephritis, is unfavorable. In patients whose previous history is vague, with persisting high blood pressure during the height of the disease, the preexistence of chronic nephritis may be strongly suspected and the prognosis may be accordingly framed. Bradycardia.—Bradycardia during convalescence is not serious. It often follows cases of long duration in which digitalis has been given. It may follow under other conditions. In old patients with arteriosclerosis it may indicate heart-block (Adams-Stokes phenomenon) and it is serious. With meningitis bradycardia may be present early, but does not continue long and is soon followed by a small rapid and compressible pulse. Tachycardia.—Persistent tachycardia during the acute period is a grave symptom, particularly if there is progressive lowering of blood pressure with other evidences of myocardial weakness. (b) Hyperpyrexia.—Rheumatism is one of the three conditions which may be associated with the highest temperature found in the practice of clinical medicine. (The other two are sunstroke and meningitis.) The modern treatment of arthritis has unquestionably reduced the incidence BACTERIAL DISEASES 287 of hyperpyrexia. Hyperpyrexia with rheumatism is more frequent in hospital than in private practice. Hyperpyrexia, is always life threatening; there are usually symptoms referable to the meninges, kidney, and to the heart. Wild and active delirium is followed by coma; these symptoms may follow each other in rapid succession. The patient is cyanosed, conjunctiva is congested, Kernig symptom is present, there may be convulsions (particularly in children), there is albuminuria, concentrated and acid urine, materially reduced in quantity and evidences of rapidly failing heart strength. In some cases there are paralyses with spasticity. The duration of cases with marked hyperpyrexia is short. Death may follow in from twelve to forty-eight hours. Many of these cases are the prototypes of Trousseau’s “cerebral rheumatism.’’ With hyperpyrexia, the prognosis is almost always fatal. We have never seen recoveries, when, with the symptoms mentioned, the tempera- ture has mounted above 106°F. In rare cases the temperature may reach as high as 108°-110c before death. (c) Brain and Nervous System.—Meningitis (see Hyperpyrexia, preceding paragraphs) is usually a fatal complication of rheumatism. There are cases of transitory meningismus in children and in adults which recover without the development of active or progressive meningitis. Delirium and other mental symptoms are not uncommon during the acute period; these are not of serious import in most cases. But few' severe or widespread arthritides are exempt from psychic disturbances. They are often marked in young subjects, in alcoholics and in the plethoric; but are by no means limited to these. Acute psychoses are occasionally present with hallucinations; at times active mania and manic-depressive states, also stupor. These conditions are rarely lasting, they are of toxic origin and yield in the course of a few weeks to several months. Neuritis may be either an early or a late complication. There may be multiple neuritis or a single nerve trunk may be involved. Most peripheral neuritides are.associated with more or less muscular atrophy. The single neuritides may include either the sciatic, the motor oculi, the trifacial or other nerves. The prognosis of all forms of neuritis with arthritis is good. (d) The Blood.—Uncomplicated cases of polyarthritis wdth fever and joint swelling show an average leukocytosis of 15,000; higher counts are rare. Serious infections with complications such as pleurisy, pericarditis, pneumonia, etc., present much higher leukocytic counts. Improvement, fall of temperature and reducing swelling of the joints, is followed by a lowered leukocytic count. Fresh infection may be sus- pected when there is a sudden leukocytic increase. Naegeli showed that there is a decided neutrophilic increase, occasionally mononuclear also. At the height of the acute symptoms there is a decided decrease of 288 SPECIFIC INFECTIOUS DISEASES lymphocytes and eosinophils; an increase of these is found with improve- ment of constitutional and local symptoms and argues in favor of an early convalescence. Anemia is characteristic of acute arthritis, there is a prompt destruc- tion of erythrocytes in severe cases, and the blood elements including the red corpuscles and hemoglobin reform very slowly during convalescence. Persistent anemia is always a serious indication. Fibrin and blood plates are always increased. Cases beginning with typhoid symptoms, in which there is slight en- largement of the spleen (Naegeli), may prove puzzling for diagnosis and prognosis. In these, the leukocytosis and increase of fibrin preclude the possibility of typhoid. Joint symptoms develop after from thirty-six to sixty hours in most cases. (e) Lung and Pleura.—Pneumonia.—Croupous or bronchopneumonia may complicate rheumatism. Pneumonia is an occasional terminal infec- tion in alcoholics, in the aged or in children. Croupous pneumonia is not often the cause of death. When pneumococcemia or other types of pneu- monia are complications, they are secondary. (See Pneumonia). Hypo- static bronchopneumonia may complicate the more serious and persistent cases. (See Bronchopneumonia). Pleurisy.—Pleurisy may be due to extension from the pericardium; when associated with endocarditis and pericarditis, in the presence of large serous effusion it adds to the discomforts of the patient and to the dangers. Recovery is possible, and follows in a large proportion of cases. It has been our experience that the exudate is promptly absorbed, also that the symptoms yield to one or two aspirations. The association of pleuritis and pericarditis (polyserositis) was found by Mosler in 15 of 142 cases of arthritis; in these the prognosis cannot be given early. The cases demand long periods of observation that the re- sulting adhesions and heart damage may be considered. Empyema.—Empyema does not often complicate rheumatism; when it does it is secondary. It yields to radical treatment unless the underly- ing sepsis or pyemia is overpowering. Bronchitis.—Bronchitis associated with rheumatism, unless second- ary to serious heart lesions, is usually insignificant. (f) Kidney .—Albuminuria with rheumatism does not necessarily in- dicate the presence of nephritis and though frequent, particularly during the febrile period, it is not per se of serious import. Concentrated acid urine is the rule and does not materially in- fluence the course of the disease. It offers indications for treatment, which when recognized, can in most cases be controlled. Nephritis is a rare complication. With mixed infection, cases that prove to be septic, or with infarct due to malignant endocarditis, renal changes are ominous. BACTERIAL DISEASES 289 (g) Peritonitis and Appendicitis.—In a large experience we have met but one case of rheumatic peritonitis; it ended fatally. Jochmann has never seen a case. Appendicitis is in some cases held to be of rheumatic origin. There are cases which remain unexplained; some are associated with or follow tonsillitis; it may be that these are dependent upon the same infection. However, the question is still sub judice; Poynton and Paine have caused it experimentally with an organism which they isolated from cases of rheumatism. (h) The Skin .—Sudaminous eruptions are the rule and are unim- portant prognostically. Erythematous eruptions, intertrigo and occasional herpes, are with- out prognostic significance. Erythema nodosum.—Erythema nodosum is unquestionably of in- fectious origin and presents many of the earmarks of rheumatism and should in the present state of our knowledge be classified with it. Children suffer oftener than adults. Only rarely are there serious complications referable to vital organs (heart, etc.). The prognosis is uniformly good. The duration varies, the disease may run an acute course in seven to ten days, may show tendency to relapse, may become subacute and in rare cases, usually in the adult, becomes chronic. (i) Rheumatic Nodules (Meynet).—These nodules first described by Meynet are about the size of a pea, rarely larger; they are located on the fingers, hands, wrists and in the neighborhood of the elbows. They rarely form during the height of the disease, usually follow the febrile period. Osier says they are common in children with mitral lesions. All authors have found the nodules oftener in children than in adults. Kemp holds that “the presence of rheumatic subcutaneous nodules has a definite bearing on prognosis, and when present, especially in children, are always accompanied by gross damage to the heart.” They are more frequent in children than in adults. They probably hold infecting agents and are responsible for fresh attacks. Rheumatic nodules do not in- fluence prognosis in adults materially. (j) Septic Conditions.—The septic condition is due to mixed infec- tion, is always serious when complicating rheumatism. It may be either early or late and is likely to be associated with septic endocarditis, septic thrombo-myocarditis and offers an unfavorable prognosis (See Sepsis and Malignant Endocarditis). In occasional cases symptoms of septic fever precede polyarthritis (non-suppurative) during several days before there are positive evidences of joint disease. Many of these recover. Sepsis is in rare cases associated with multiple suppurative arthritis. In some of these, the septic condition precedes the joint symptoms during several days. Thorough search usually reveals the primary focus. Our 290 SPECIFIC INFECTIOUS DISEASES experience with these cases has been unfavorable; they often present the clinical picture of malignant septicemia. (k) Purpura.—Whether purpura rheumatica should be included in the consideration of polyarthritis remains undecided. In this work it will be separately considered (See Purpura). Purpuric and hemorrhagic conditions complicating arthritis are al- ways suggestive of malignant infection and demand a guarded prognosis. When purpuric conditions are due to hemophilia or are attributable to the usual causes of non-malignant purpura (purpura simplex, rheumatica, and hemorrhagica) the prognosis of arthritis is not unfavorably influenced by the complication; on the other hand, septic conditions, with limited or ex- tensive petechise, with or without endocarditis, are always serious. These conditions are embolic. Blebs or vesicles which contain blood often show a tendency to necro- biosis of the underlying cutis, are also of embolic origin, and are evidence of malignant infection. VI. Duration It is never safe to make a prophecy which will commit the clinician to a time limit of polyarthritis. It is absolutely impossible in any case to give any reliable information on the subject, for apparently mild cases at the beginning finally prove to be rebellious to treatment and those in which the initial symptoms argue in favor of a long period of arthritis often run a short course. Number of Joints Inflamed.—The early and persistent inflammation of a single joint (monarthritis) in the majority of cases argues in favor of a slow process and occasionally leads to subacute disease or chronicity. In rheumatism the prognosis as to length of time the disease lasts seems, as the result of the observation of many clinicians, in many series of cases, to be less favorable when the disease is monarticular and stationary, than with the invasion of several joints or the leaping of the disease from joint to joint. If with polyarthritis the features of the disease change, and one joint is selected with tendency to thickening and swelling, a long period may be expected during which the local and some constitutional symptoms will continue troublesome. Migratory lesions of the joints often yield within a reasonable period. Recurring rheumatism is usually either subacute or may approach chronicity. It is not at all unusual to find the second or the third attack associated with endocarditis and multiple joint invasion continuing dur- ing four to eight months. The average duration of the benign case is from three to six weeks. BACTERIAL DISEASES 291 VII. Environment and Social Conditions In considering the factors which influence the course of the disease we referred to sunlight, dampness and other baneful conditions which lower the resistance of the patient; these are also included in the study of the environmental and social factors which influence prognosis. Un- healthy homes, faulty ventilation, insufficient and faulty food, humidity, exposure, dissipation, excesses of all kinds prepare the culture media within the body which are needed for the proliferation of the micro- organism which is the cause of the disease. It is not at all unusual to find patients who have suffered repeated attacks of arthritis relieved permanently by a change of residence or climate; in other cases, change of occupation and methods of living prove to have a wholesome influence. VIII. Relapse Relapses are frequent, and exert an enormous influence on the subse- quent history of these patients because endocardial complications are aggravated and valvular deformities are thereby increased. Relapse often leads to chronic changes in the joints with deformities and muscular atrophies. Muscular atrophies increase with each attack of rheumatism, particularly with those forms in which the symptoms continue subacute during long periods and remain limited to the same joints. IX. Immunity Arthritic infection is not followed by immunity. In many a predis- position is developed which invites repeated attacks. It not infrequently happens that the predisposition continues during four to six years follow- ing the initial attack, after which there may never he a return of the disease. These facts thoroughly appreciated by life insurance companies have led to the postponement or rejection of applicants during a number of years after acute attacks of arthritis.

Tonsillitis The Influence of the Tonsil on Prophylaxis and Prognosis The tonsil serves as the port of entry of pathogenic organisms and has an enormous influence in spreading infection to distant organs through the chain of lymphatics with which it is intimately connected and through the hlood-stream. The normal tonsil harbors disease-producing micro- organisms at all times; the diseased tonsil is a greater menace, for in its crypts conditions are offered which invite local proliferation and con- secutive constitutional infection. All changed, enlarged and adherent tonsils powerfully influence the prognosis of many pathologic conditions. I considered the influence of the tonsils in connection with the study of tuberculosis. (See Tuber- culosis.) Recent investigations by Mitchell dealing with the infection of children with bovine tuberculosis accent their importance and prove the enormous influence of the faucial tonsils in tuberculosis of the upper cervical glands; they also prove that in a large proportion of cases a well- marked tuberculosis of the deep glands “is secondary to a small tuber- culous focus in the tonsil.” In children, Mitchell reportsi the “high per- centage of faucial tonsils in which the bovine virus was present,” and claims it “is further striking proof of the frequency of tuberculous cows’ milk as a source of infection.” Wood in 1,671 cases showed, that in 88 (or 5.2 per cent) the tonsils were tuberculous. Lartigan contends that Wood’s figures are less reliable than his own in which he did not rely upon histologic studies alone, but added the results of inoculation tests and found that 12 of his 75 cases gave positive results to animal inocu- lation and therefore placed the percentage of tubercular involvement of the pharyngeal tonsil at 16. Tonsils in which there are no apparent changes have been proved experimentally and clinically to hold the organisms of cerebrospinal meningitis, pneumonia, rheumatism, streptococcus endocarditis, poliomye- litis and many other grave diseases, and have served as the port of entry of these disease-producing agents. Further it may be contended with considerable certainty that many chronic disases, the causes of vjhich have not been understood in the past, are being favorably influenced by the enucleation of both large and small BACTERIAL DISEASES 293 tonsils. Among these diseases are the various forms of so-called chronic rheumatism and rheumatoid arthritis. There are acute infections of the tonsils in which these organs are involved. Among these are diphtheria and suppurative peritonsillitis. To such tonsils, after convalescence has commenced, serious constitutional disturbances which threaten life may be traced; they continue to hold in their crypts and tissues colonies of the original pathogenic microorganism which they throw into the blood-stream from time to time. Pyemia, sepsis, nephritis and other infections have followed from such source. Diphtheritic paralyses, in which there are acute exacerbations with evidences of sensory neuritis, have been favorably influenced by the enucleation of tonsils, in which, weeks after the acute process had run its course, diphtheria bacilli were found. In a number of cases of Hodgkin's disease there has been a clear his- tory of persistent enlargement of cervical glands following tonsillar infec- tions. In some of these, the glands remained stationary during a number of months before showing the progressive enlargement and extension of the fatal disease. The prophylaxis and prognosis of many constitutional diseases as well as many conditions, the cause of which we have been unable to under- stand, will be favorably influenced by the thorough appreciation of the importance of the faucial tonsil as a reservoir from which many and serious infections may proceed, and the further fact that the defensive function of the organ is readily overcome. Acute Follicular Tonsillitis Angina, Amygdalitis, Streptococcus Tonsillitis Tonsillitis is an acute infection of the tonsil leading to inflammation, membranous deposit, constitutional disturbances, occurring usually dur- ing early life, with complications either early or late which may lead to grave organic changes in one or more organs. It may he sporadic or epidemic. Most acute tonsillitides are of streptococcus origin. The majority of these run a favorable course and lead to convalescence with considerable weakness, and at times long periods of ill-defined symptoms with a general condition below par. Sporadic Cases.—There are acute sporadic cases in which, for sev- eral days, there are free and outspoken constitutional manifestations, including, with the tonsillar lesions, high temperature, rapid pulse, mitral systolic murmur due to muscular insufficiency and albuminuria; often there are evidences of nephritis. These cases under treatment and rest offer a good prognosis; rarely does death follow except in those reduced by previous disease, burdened by depressing and undermining diatheses or some one of the early complications to be mentioned later. 294 SPECIFIC INFECTIOUS DISEASES The subsequent history proves the importance of the infection as a cause of chronic and permanent disease in neglected and malignant strep- tococcus infections. In all cases the extent of the glandular invasion (enlarged cervical glands) is an index of the depth of the infection. There are all grades of severity in the sporadic cases. Streptococcus tonsillitis may accompany and materially influence the course of other infections; among these are influenza, measles, scarlet fever, infantile paralysis, cerebrospinal meningitis, and in young children bronchopneumonia occasionally. In rare cases it may precede these infections. Sporadic cases may infect entire households or wards of hospitals and it sometimes happens that an outbreak of streptococcus tonsillitis in a surgical ward leads to erysipelas among the operated cases. Mild sporadic cases run their course in from three to six days. Those with marked constitutional disturbances average between six and nine days. Convalescence is usually slow, sequelae are numerous and often serious. These will be considered with the epidemic type of the disease. Endemic and Epidemic Streptococcus Tonsillitis.—The most frequent source of endemic or epidemic tonsillitis is infected milk. The infection is almost always due to organisms belonging to the streptococcus group. Miller, who investigated the Chicago epidemic, found that “an epidemic of mastitis existed in cows and sore throat in farmers” in the territory which supplied the contaminated milk, and emphasizes the fact that “streptococci which cause mastitis in cows may be pathogenic for animals and virulent to man.” Epidemic streptococcus tonsillitis which prevailed in Cortland and the adjacent counties of Central Yew York during .1912 was virulent and was the cause of many deaths. The old and feeble, also very young children offered lowered resistance. The complications of the Cortland epidemic were numerous and included nephritis, endocarditis, pneumonia, metastatic parotitis (see Metastatic Parotitis) and a variety of conditions which lead to tardy convalescence. Capps and Miller made an exhaustive report of the Chicago epidemic due to the contaminated milk supply above mentioned; 10,000 cases were included. Epidemic cases are always much prostrated by the infection and show marked leukocytosis. Second attacks within a few days are frequent and lead to slow convalescence. Capps and Miller report peritonsillar abscesses in occasional cases which, when promptly opened, lead to prompt recovery. Complications.—The unfavorable cases are those in which there is bac- teremia, which leads to numerous complications. Otitis media compli- BACTERIAL DISEASES 295 cated 6 of 173 typical cases observed by Capps and Miller. Arthritis is a frequent complication of epidemic tonsillitis; it is present in 10 per cent of the cases and occasionally leads to suppuration of the joints. Erysipelas complicated two cases seen by us during the epidemic in Cortland and adjoining counties. In one, the complication was migra- tory, covered the entire body in its acute exacerbations; the patient, a man aged about thirty, finally developed streptococcus meningitis and died. The other case was a woman who recovered. She was over seventy, developed secondary pneumonia, suppurative metastatic parotitis and erysipelas, after initial streptococcus tonsillitis. Nineteen of the 173 cases reported by Capps and Miller died. Nine of these died of peritonitis, four of pneumonia and three of septicemia. An investigation made at the time of the Cortland epidemic by Dr. Charles E. North of New York City, who, with two assistants, cooperated with the Public Health Committee of the Cortland County Medical Society, resulted in, the finding of two cows in one dairy that were affected with garget. This dairy furnished about 7 per cent of the total milk supply and tabulation showed that this dairy furnished milk to families in which about 72 per cent of the whole number of cases occurred. Eleven throat cultures were examined and all of them revealed the presence of a certain species of streptococcus of the same type found in the discharge from the udders of the two affected cows. Of 669 cases 13 died, cause of death as follows: Age. Cause of Death. 50 Edema of Larynx. 51 Heart Failure. 69 Lobar Pneumonia. 39 Peritonitis. 66 Peritonitis. 60 Peritonitis. 62 Peritonitis. 70 Erysipelas. 80 Erysipelas. 82 Pneumonia. 72 Heart Disease. 78 Erysipelas. Unknown Peritonitis. In addition, there were reported seven other cases of erysipelas; nearly all cases had enlarged cervical glands, many of them forming abscesses; and a very large number of protracted cases of rheumatism. Also cases of pleurisy and pericarditis. Epidemic cases occasionally run a prolonged course—three to seven weeks, after which the convalescence is slow and the patient continues weak during a long time. Mild cases recover in from two to three days. Heart Complications.—The cardiac complications which follow all 296 SPECIFIC INFECTIOUS DISEASES forms of tonsillitis may be either due to streptococcus endocarditis and myocarditis, to relative insufficiency of the myocardium, to functional disturbances depending on the reduced state of the patient or to distant complications, such as nephritis, arthritis, et cetera. All of these offer a favorable prognosis except those forms of malignant endocarditis of streptococcus origin. Permanent damage often follows in the non-malig- nant cases and the patient recovers with an irritable heart and valvular lesions. In these cases, either with subsequent tonsillitis or without, there are acute endocardial exacerbations in which there may be complications which are serious, including nephritis and possible cardiac insufficiency and increasing anemia. Many of these patients fall into extremely dan- gerous conditions including general dropsy, from which they may with proper care and treatment recover, i. e., return to their former state with an added endocardial scar. Pericarditis if purulent complicating or following tonsillar infection is always serious. Hot all murmurs following streptococcus tonsillitis are due to endo- carditis. The majority of mitral systolic murmurs are due to relative muscular insufficiency and disappear as the patient regains strength. Chorea is frequently associated with an initial tonsillar infection; there is with these cases often acute endocarditis. The prognosis is good; in obese children endocarditis may be severe and occasionally, without relief of the choreic symptoms, the child dies. Malignant endocarditis may prove to be a sequel. Functional disturbances causing arhythmia and annoying intermis- sions and irregularities also yield after long periods of rest. Bradycardia is an occasional sequel or an accompaniment of the acute stage, without unfavorably influencing the prognosis. Kidney.—Nephritis, which follows within seven to twenty-one days after acute tonsillitis, is often rebellious and occasionally leads to dropsies and to fatal uremia. Early nephritis and albuminuria usually yields during the slow con- valescence. Arthritis (Rheumatism).—Arthritis is a frequent complication of tonsillitis and shows the characteristics of polyarthritis in most cases, is often complicated with endocarditis, is subject to relapse and usually leads to full recovery without permanent damage to the joints invaded. (See Polyarthritis.) Paralysis.—We have never chanced to find a single case of paralysis in which the bacteriologic diagnosis of streptococcus tonsillitis was posi- tive. Such cases are recorded, but must be exceedingly rare. Septicemia without, evidences of local disturbance or with endocarditis is the most serious sequel of tonsillitis. It offers only the most unfavorable forecast. BACTERIAL DISEASES 297 Among the other complications of streptococcus tonsillitis are osteomyelitis, appendicitis, empyema, liver abscess, perinephric abscess, meningitis, and empyema. (See separate chapters for further prognostic data.) Pneumonia.—The prognosis of streptococcus pneumonia following tonsillitis depends on the factors fully considered in connection with the pneumonias. (See Pneumococcemia.) Generally speaking it may be concluded that the migratory types of the disease offer a grave prognosis, the acute cases justify the figures and conclusions to which reference has been made elsewhere. (See Migratory Pneumonia.) Mortality.—Our average mortality of all forms of streptococcus tonsillitis in private practice does not reach 2 per cent. Hospital statistics include neglected cases and show a higher mortality. Phlegmonous Tonsillitis. (Septic) In occasional infections there are marked constitutional symptoms, nephritis, large albumin loss and destructive gangrenous changes in the tonsils, foul smelling with symptoms of deep sepsis at once, including delirium and final coma which lead to death in from three to seven days. These cases are rare, they occur in adults as a rule, and before death show decided purpuric tendencies; they are not to he confounded with suppurative tonsillitis. Acute Suppurative Peritonsillitis Quinsy, Peritonsillitis Most forms of quinsy invade, besides the tonsil, the 'peritonsillar tissue; they may be either primary or secondary. When secondary the suppuration may he a complication of general infection (pyemia, septicemia, scarlet fever, typhoid, erysipelas, et cetera) or it may he associated with nephritis, diabetess or other constitur tional diseases. Syphilitic and carcinomatous ulcers at times lead to tonsillar suppuration. Most primary suppurative peritonsillitides offer a good prognosis if rationally treated. Edema of the glottis and larynx is at times a sudden complication with both primary and secondary tonsillar suppuration and unless promptly relieved by surgical means ends fatally. Edema of the uvula complicates all cases of suppurative peritonsillitis. The prognosis of the acute secondary suppuration of the tonsil per se is not bad; occasionally it suddenly leads to edema particularly in cases of chronic and acute nephritis and threatens life. The nature of the 298 SPECIFIC INFECTIOUS DISEASES disease naturally influences the prognosis of the associated sup- puration, but as a rule the patient recovers from it. Some subjects develop primary suppuration of the tonsil and peri- tonsillar tissue repeatedly at short intervals; in almost all, the prognosis is good and recurrence is prevented by the excision of the tonsils. Ulceration of large arteries with consecutive bleeding (internal caro- tid artery) is exceedingly rare. Convalescence is often very slow and patients are subject to many of the complications of acute non-suppurative tonsillitis. (See Acute Ton- sillitis.) (e) Vincent’s Angina Vincent’s angina is due to a fusiform bacillus which may also cause noma (see Cancrum Oris), laryngitis, pneumonia, mastoid inflammation and bronchopneumonia. The bacillus was found by Tunnicliffe to be the pathogenic germ in a case of pyemia. The germ is usually found in connection with other disease-producing organisms (aerobic). Halsted says that “like the other organisms with which it is associated, it occurs in healthy mouths, but more particularly in mouths and throats in which there is some unhealthy condition, such as diseased tonsils, decayed teeth and inflamed gums” . . . “it rarely produces disease when the tonsils, teeth and mucous membranes are in a normal condition.” Vincent’s angina may accompany any of the tonsillar infections of diphtheria, scarlet fever, syphilis, streptococcus or other inflammations associated with the formation of false membranes. Rolleston in 18,187 cases in which diphtheria was suspected admitted to the London Metropolitan Hospital Board that he found during 1905- 1907, 3,047 non-diphtheritic cases; of this number 95 were due to the fusiform bacillus, or Vincent’s angina. The disease presents in an ulcerative or destructive form, or remains membranous. Two cases reported by Halsted proved to be fatal. Pearce in his cases found great prostration with feeble and rapid pulse, marked involvement of the nervous system, the hippocratic facies and death from toxemia. Purpuric symptoms argue in favor of malignancy of infection, as does also necrosis of included tissue. The clinical picture of the malig- nant cases is much like the fatal cases of cancrum oris. The prognosis is worse in patients who are reduced and previously infected. The limitation of the disease to the tonsils without marked constitutional symptoms offers a good prognosis. Invasion of the larynx adds an enormous element of danger, particularly during early life. Non-diphtheritic membranous croup and tonsillitis should always create a suspicion of Vincent’s angina. The diagnosis can be cleared only by bacteriologic tests. BACTERIAL DISEASES 299 Ulcerative stomatitis may be caused by the fusiform bacillus without involvement of the tonsils.

Chronic Tonsillitis (Chronic Naso-pharyngeal Obstruction, Mouth Breathing, Aprosexia, Adenoids of the Pharynx) Chronic tonsillitis may result from preceding acute tonsillar infection and may include persistent enlargement of the neighboring lymphatic glands or it may be a part of a chronic hypertrophy of all the adenoid tissues of the pharynx in which the vault of the pharynx is occupied by succulent adenoid structures which cause mouth breathing and many secondary changes. The influence of adenoids and chronic enlargement of the tonsils on the growing child is paramount. Development, both mental and physical, is impeded by the handicap which results. Insufficient oxygenation is one of the results of the obstructed breathing. The advance of rhinology has been of great value in calling the attention of the profession to the far- reaching effects of chronic tonsillitis, adenoids and associated lymphatism. The facies of the children suffering from adenoids are characteristic. The direct results of faulty breathing due to the disease are, besides those mentioned, developmental anomalies of the thorax, chicken breast, barrel chest, and funnel breast. Deafness or faulty hearing is frequent. Con- vulsive tics are occasional. These children are hypersensitive, contract the acute infections which spread from the tonsils oftener than do normal children, their breaths are offensive, the crypts of the tonsils hold foul- smelling cheesy masses and when they develop scarlatina the throat symp- toms are always severe. The removal of the tonsils and the adenoids promptly changes the picture and from a stupid, mouth-breathing, sickly and apathetic youngster, there is a complete metamorphosis to a normal child in almost all cases. Captain Catlin in his pamphlet published in 1861 probably overestimated the importance of adenoids and enlarged tonsils, when he contended that to these anomalies all of the ills of man- kind are attributable, but there is much of value and truth in his aphorism. “Shut your mouth and save your life.” 300 SPECIFIC INFECTIOUS DISEASES Iloffinan shows the mortality from all diseases of the tonsils to be 1.8 per cent in males and 1.1 per cent in females including 225 cases.

Metastatic Parotitis (Secondary Parotitis, Infectious Parotitis, Parotitis metastatica) Inflammation of the parotid not due to epidemic mumps may be con- sidered to be secondary to existing infection, is usually one-sided and an expression of grave constitutional invasion and malignancy of the pri- mary disease. The infections to which parotitis has been added include all forms of pyemia, typhoid fever, scarlet fever, pneumonia, dysentery, cholera asiatica, malignant endocarditis, streptococcus infections, sinus thrombosis, cerebrospinal meningitis, small pox, angiocliolitis, yellow fever, all naso- pharyngeal infections, syphilitic ulcerations of the mouth, peptic ulcers, measles, tuberculosis and in rare cases mild infections and mumps lead to chronic enlargement of the gland. Many of these melastases are due to direct infection through the mouth and some of these might be prevented by more thorough cleansing of the upper air passages and the nasopharynx, more particularly, than is usually practiced. The glandular ducts and gland substances themselves may serve to infect and finally a large number of secondary parotitides may be traced to infection through the blood stream. During a recent large epidemic at Cortland, Mew York, which was traced to milk infection, of streptococcus origin, I saw a case with Dr. Higgins of streptococcus tonsillitis in a woman over 70 years of age who developed streptococcus pneumonia, then streptococcus parotitis, with small pockets of degeneration and suppuration, who finally made a full recovery. This history with its fortunate outcome is rarely repeated. With most serious infections the development of secondary parotitis may be viewed with concern. It is an evidence of the gravity of the original infection and adds an element of danger at the same time. In some cases suppuration advances to the cellular tissue of the neck (Angina of Lud- NON-BACTERIAL EUNGUS INFECTION 301 wig) and to the ear and skull, when sub-acute and chronic infection may follow with facial paralysis, caries or meningitis. Tuberculosis invading the parotid may cause caseation. Metastases to the parotid occur with equal frequency in children and adults. Early metastases to the parotid are more serious than the late infection of the gland. The invasion of the parotid during acute gouty arthritis is a painfnl and weakening complication which, as a rule, yields to treatment in from two to three weeks without suppuration. C. Diseases due to Non-Bacterial Fungus Infection 1. Actinomycosis (StrahlenpilzkranJcheit) Actinomycosis is caused by the Actinomyces bovis (Ballinger, 1877), also known as the uray fungus,” which is a Gram-positive streptothrix. The disease is found in animals—horses, pigs and other cattle—most frequently involving the jaw, mouth and tongue, and is in all probability caused by the eating of ordinary grain or barley holding the actinomyces. Man is more frequently infected than woman (3-1). The disease leads to a condition of subacute or chronic pyemia .due to the infiltration and suppuration of the infected tissues, around which there is promptly connective tissue proliferation. In man as in cattle the jaw and tongue are the usual foci of the disease, though other parts of the body may be infected. The ac omycetes as they enter the tissues cause hyperemia, infiltration, chronic suppuration and consecutive con- stitutional disturbances. The diagnosis can be made positive by the pres- ence of the ray-fungus in the pus. The characteristic swellings of the disease may follow in any part of the body to which the streptothrix is carried and the fungus may migrate to surrounding tissues and organs or in severe cases blood vessels may be invaded, more particularly veins, which opens the avenues for the entrance of actinomycetes into the blood stream and their dissemination to distant organs (lung, liver, brain, etc.). The disease may invade: 1. The alimentary tract 2. The respiratory tract 3. The skin 4. The brain or other internal organs. Forms of Actinomycosis 302 SPECIFIC INFECTIOUS DISEASES 1. Alimentary Actinomycosis.—The course of alimentary actinomy- cosis, the most frequent form of the disease, is characteristic. The fungus finds a point of entrance in the mucosa surrounding carious teeth, through the mucosa of the floor of the mouth or through the tonsils. The changes already mentioned promptly follow; the local swelling depends upon the direction of growth and the extension of the fungus and the amount of infiltration and suppuration. As a rule there is more or less 'periostitis of the jaw and there are fistulous tracts which discharge a thin yellow pus, in which the yellow ray-fungi are promptly detected. The tongue is less likely to show suppuration than the surrounding tissues, hut the separate nodules are readily palpated. The posterior pharyngeal wall may be invaded when the disease may extend downward attacking the esophagus which it may perforate. As the process progresses the stomach and intestinal mucosa may be infiltrated. Perforative peritonitis due to intestinal perforation may follow. Appendicitis develops in occasional cases. Intestinal actinomycosis may lead to fistulous openings through the abdominal wall, to abdominal swellings and adhesions of intestines or to intestinal stenosis. The pos- terior mediastinum may be attacked through migration of the actinomyces and the pleura and the lungs invaded through this avenue. 2. Actinomycosis of the Respiratory Tract.—Actinomycosis of the respiratory tract is rare, save as it is secondary to alimentary invasion or follows the aspiration of infected foreign bodies. The fungus causes an obstinate fetid bronchitis or as a rule the dependent part of one lung is slowly infiltrated (chronic pneumonia) causing constitutional symptoms, including fever, rapid heart action, increasing emaciation, and the expec- toration of purulent sputum, with fungi and acid crystals. In chronic cases there is adva to the pleura and to the chest wall, with chronicity and consecutive deformity. In pulmonary actinomycosis the pericardium may also be the seat of deposit. 3. The Skin.—The skin, through an abrasion or wound may be in- vaded by the fungus and multiple lesions result vfith the symptoms of chronic pyemia accompanying the suppuration. 4. The Brain and Other Internal Organs.—The brain and liver inva- sions are found in those cases in which the actinomycetes have invaded the walls of a blood vessel and have been carried to these organs through the blood stream. In the brain the symptoms of tumor are prominent and death is the result, the duration varying in accordance with the location of the deposit. The liver, when involved, presents the symptoms of abscess of that organ and offers an unfavorable prognosis unless the abscess is superficial and operable. DISEASES DUE TO METAZOAN PARASITES 303 Prognosis of Actinomycosis The prognosis of all forms of actinomycosis must depend on the loca- tion of the disease, the ability to remove the focus early by radical surgical treatment. When the disease is disseminated the chances of recovery by medical treatment are small. Spontaneous recoveries have been reported, but are rare and can only be imagined to have followed limited swelling. The chronic pyemia of unrelieved cases wdth its long periods of remittent fever leads to exhaus- tion, emaciation, and after months of suppuration, with increasing anemia and edema, albuminuria with other positive evidences of far-reaching amy- loid degeneration of the internal organs develop and death results. It may be positively concluded that the skin infections offer the most favorable prognosis. When the neck and face are the seat of the disease, Poncet and Thevenot found that death followed in one case in 16; with lung and abdominal (visceral) actinomycosis 25 per cent died. Reference Poncet & Thevenot. Lommel, Handbuch der Inneren Medizin (Mohr and Staehelin). 1911. D. Diseases due to Metazoan Parasites (.Internal Parasites) Of the animal parasites which infect the body (non-microscopic), (1) the tapeworms or cestodes, and the (2) round worms, or nematodes, are the most important. 1. The principal varieties of the Cestodes are: (a) Tenia solium. (b) Tenia saginata or mediocanellata. (c) Bothriocephalus latus. (d) Tenia echinococcus (or hydatids). 2. The Nematodes are: (a) Ascaris lumbricoides. (b) Oxyuris vermicularis. (c) Ankylostomum duodenale or hookworm. (d) Tricocephalus dispar. (e) Trichina spiralis. (f) Filaria sanguinis hominis. 3. The Bilharzia hematobia belongs to the Trematodes and also de- mands consideration. 304 SPECIFIC INFECTIOUS DISEASES 1. Cestodes (a) Tenia solium (Armed Tapeworm) This worm is not as common in English speaking countries as is the Tenia saginata. It is due to the eating of improperly cooked or raw pork. When fully grown it is from eight to twelve feet long and inhabits the small intestines, where as a rule it is solitary, though multiple tenke are not uncommon. Its life history and other characteristics are best studied in works on pathology and diagnosis. It must be remembered, however, in connection with the cysticercus of the worm, that it may in occasional cases lodge in one or more vital organs of man and give rise to local changes and symptoms. To this I will again refer. The armed worm as a rule causes no serious symptoms and does not threaten life; the passage of the head is assurance that the host has been freed. If the head in its passage escapes discovery or if the proglottides are passed without the head, the host continues uncertain of the fate of the worm during several, usually three months; the time required for the development of the worm and the passage of its proglottides. While the symptoms caused by the Tenia solium are not of serious import, the worm may by its presence interfere with stomach and intestinal functions, causing nausea, diarrhea, other symptoms of indigestion, in- cluding abnormal appetite, loss of flesh and mental torpor; with some anemia, all of which symptoms disappear with the passage of the worm. The worm eliminates a 'poison which enters the blood stream and is directly responsible for the eosinophilia and anemia which are constant accompaniments of the tapeworm and of many other intestinal parasites. The prognosis of the fully formed tapeworm as it inhabits the intes- tinal tract from the study of its life history and the preceding paragraphs may be said to be uniformly good and is readily influenced by suitable anthelmintics. The deposit of the cysticercus in the brain may cause but few or no symptoms, in occasional cases the brain may tolerate the growth during long periods, depending upon the seat of the tumor caused by it; on the other hand it may threaten life by its presence and may cause the usual symptoms of a neoplasm. It may infest the base and cause pressure symptoms including paralysis of one or more of the cranial nerves. It may grow to considerable size, causing destructive changes as it enlarges. The cysticercus racemosus may lie loose in brain tissue, usually in the ventricles of the brain. In occasional cases chronic basilar leptomeningitis may be provoked. Jacksonian and other forms of epilepsy, ependymitis and hydrocephalus internus, cerebral anemia and obliterating cerebral endarteritis are mentioned by Askanazy as complications due to the pres- ence of the cysticercus in the brain. DISEASES DUE TO METAZOAN PARASITES 305 The cysticercus with its dense membrane may continue to live in the tissues of man for years, may die, when calcification usually follows. The skin may harbor cysticerci, also the muscular tissue, the liver, spleen, the intestinal wall, the heart, the lung, the pleura, the lymphatics and bone, The favorite seat of the cysticercus is the brain and the eye. Cysticerci are not usually the cause of local inflammatory changes or congestion, neither do they give rise to marked sensory symptoms when in the skin. In the eye, atrophic changes may follow (phthisis bulbi) (Askanazy). (6) Tenia saginata or mediocanellata Tenia saginata is the most common form of tapeworm in man; it is transmitted by the eating of infected beef, and grows to an average length of twenty (20) feet. This variety of tapeworm causes fewer complica- tions than does the Tenia solium, may be carried without inconvenience in many cases, save the loss of the proglottides from time to time. In some cases there are colicky pains, indigestion, abnormal appetite and per- sistent malaise. Reckzeh reports the occurrence of pernicious anemia caused by the worm. The cysticercus of the saginata is rarely imbedded in the tissues of man. From 60 to 65 days lapse between the swallowing of the cysticercus and the appearance of proglottides in the stools. The prognosis of Tenia solium is uniformly good. It occasionally hap- pens that several trials must be made before the head passes, but full restoration of gastro-intestinal function to normal invariably follows the passage of the worm. (c) Bothriocephalus latus The bothriocephalus is the largest of all tapeworms, its immediate host is the fish almost always of the pike family and it is distributed over Cen- tral Europe (Switzerland) and in Japan. Tn America we occasionally find the worm in subjects who were infected abroad. The bothriocephalus usually causes greater gastro-intestinal disturb- ances than do the other varieties of tenia; these include diarrhea, persist- ent nausea, mental lethargy, depression and at times great irritability. In rare cases convulsions and other explosive nervous manifestations have been charged to the worm. The greatest danger to the host is the development of grave anemia which has all of the characteristics of pernicious anemia and is now con- sidered by hemotologists to be identical with that disease. (For the bene- fit of the student of the literature of bothriocephalus anemia I have appended the leading references on this subject from which in turn the full bibliography may be obtained). It may be assumed in the light of our present Icnowledge that the dis- 306 SPECIFIC INFECTIOUS DISEASES eased or dead bothriocephalus adds a poison to the blood stream which is hemolytic in its effect and causes the blood picture and constitutional dis- turbances of progressive pernicious anemia. Ehrlich, Biermer, Laashe and Schauman, the leading authorities on this subject have all reached this conclusion. The prognosis of even advanced cases of bothriocephalus anemia is good, if the worm, dead or alive, is promptly expelled by treatment. Full recovery is slowly reached. Schauman proved that the daily regeneration of the erythrocytes after the expulsion of the worm varied between 60,000 and 214,000. In the beginning of the improvement he found the aver- age midway between the extreme figures given; the microcytes disappeared early; macrocytes may at first be increased; later these disappear entirely and the normal blood picture is reestablished. This subject will be fur- ther considered in connection with progressive pernicious anemia. (d) Tenia echinococcus (Ilydatid Disease) The adult worm is not found in man. The worm itself is one-quarter inch long, occupies the intestine of the dog and wolf. The sheep is often the intermediate host. In man, the cysticercus stage makes him an inter- mediate host. The six booklets of the embryo set free by the digestion of the shell of the ovum, migrate through the intestinal wall and enter the blood stream or in some other way gain entrance to the brain, the liver, the spleen or other organs of the body. When the booklets are deposited they disap- pear, and the embryo is slowly converted into a cyst of small size with two layers, one external or the capsule; the other internal or the endo- cyst. The cyst ivall encloses a light clear fluid. The fluid of the cyst has an average specific gravity of 1010, neutral reaction as a rule; contains 98.5 per cent of water. Of the solid constituents sodium chlorid is in the ascendency. The albumin content is infinitesimal. The fluid con- tains a toxin which when injected into animals causes paralysis of the heart in diastole, lowered blood pressure and temperature. Soon there is a connective tissue enclosure which strengthens the cyst. Daughter cysts develop within the parent cyst and from these daughter cysts, other or grand-daughter cysts develop. The echinococcus may live many years, or may die, when remnants of the original cyst are found within the fibrous wall in the invaded organs„ calcified or otherwise changed. Cysts may rupture and according to their location give rise to symp- toms. Hydatid cysts are not frequent in America. In our practice we have seen but three. One we saw in 1878 at the Billroth clinic in Vienna (involving the neck, successfully removed) one in the clinic of Detmoldt DISEASES DUE TO METAZOAH PAEASITES 307 in Hew York (liver echinococcus), and one of liver echinococcus which died, in our own practice. Lyon recorded 241 cases of hydatid disease in the United States and Canada “and several of these occurred amongst the Icelanders settled in Manitoba.” Of the 241 cases 177 were in the liver; 26 in the omentum, the peritoneal cavity and mesentery. Eleven cysts were passed per rectum; in 7, the cysts or hooklets were expecto- rated and two escaped through the urethra. The following statistical records taken from Allbutt and Rolleston show the incidence of echinococcus cysts in the various organs of the body: In 1,000 autopsies at the Adelaide Hospital, South Australia, 49 bod- ies were found to contain hydatid cysts, i. e., 5 per cent. In 11 the cysts were multiple; in 5 two organs were infested; in 6 three or more viscera. In 36 the liver contained a cyst. In 9 the lung contained a cyst. In 6 the spleen contained a cyst. In 5 the peritoneum contained a cyst. In 4 the brain contained a cyst. In 1 the heart contained a cyst. Thomas in 1,900 cases of hydatid disease found the liver infested in 5 per cent; the lung in 11.6 per cent; the kidneys in 4.7 per cent; the brain in 4.4 per cent; the spleen in 2.1 per cent; the heart in 1.8 per cent; the-peritoneum, omentum and mesentery in 1.4 per cent. The average of all statistics shows the liver to he the seat of the echino- coccus disease in one-half of those infected. Hydatid of the Liver.—There may he one or more cysts in the liver; the right lohe is the favorite location of these. The prognosis for life depends on the fate of the cyst, its location, size and the mischief which its presence causes. Suppuration of Liver.—Echinococcus cysts may lead to grave constitu- tional and local disturbances, which unrelieved by surgical interference usually leads to death. Perforation of hydatids of the liver may take place into one or more of several surrounding organs; into the stomach; the intestines; the peri- toneal cavity; the lung; the bronchus; the kidney or into the portal vein. Rupture into the lung or pleura may lead to fatal pneumonia, to gan- grene, to empyema, sudden asphyxia, pyo-pneumothorax and threatening hemoptysis. With all perforations there is besides the local lesions great danger of poisoning by the entrance of toxins from the fluid of the cyst. After aspiration of the cyst in many cases, distressing urticaria, also an evidence of toxinemia is frequent. Hence aspiration adds to the dan- gers unless operation follows immediately. A large number of liver cysts remain latent during many years and the carriers die of intercurrent disease. 308 SPECIFIC INFECTIOUS DISEASES Death may be caused by compression of 'the portal vein or toxinemia associated with obstruction of the bile passages. Fistulous openings may result from the suppurating of liver cysts, and their burrowing to the surface; such patients unless relieved by surgi- cal interference die from sepsis, emaciated and with the cerebral symptoms of toxineniia. Spontaneous cure may follow perforation; not of sufficient frequency, however, to justify expectant treatment. All operable cases of single liver echinococcus cyst offer a good prog- nosis. Multiple liver cysts are almost uniformly fatal. Hydatid Cysts of the Lung.—Hydatids of the lung, as already stated, represent 11.6 per cent of those who suffer from echinococcus disease. Pleural invasion may lead to the symptoms and include the dangers of effusion, compression and its results. In many cases encysted hydatids in the lung do not threaten life; they may cause few or no symptoms. In other cases compression with inflammatory changes, cavity formation, per- foration, occasionally into the pericardium, septic fever and repeated hem- orrhages follow, with occasional perforation into the pleura; empyema and pyo-thorax. Death follows lung hydatids in one-third of all cases. Hydatid of the Kidney.—Echinococcus of the kidney may he present without interfering with the health of the host during many years. They may be passed per urethram and without consecutive damage to the genito- urinary tract. In some cases the entire kidney is converted into a sac giving the physical signs and subjective symptoms of hydronephrosis. The prognosis is good, when, as a rule, the condition proves to be operable. Rupture into the pelvis of the kidney is the usual fate of the cyst; this is followed by pyuria, fever and offers a good prognosis when radically treated. Spontaneous recoveries are recorded after rupture. Kidney cysts may rupture into the peritoneal cavity, causing perito- nitis; into the lung or bronchus, when the prognosis is unfavorable. The external rupture of kidney hydatids offers a good prognosis, the removal of the kidney with included cyst usually leads to cure. Hydatid of the Spleen.—This condition is rarely recognized without exploration, aspiration or post mortem. Its surgical treatment is prompted and justified by the physical signs of enlarged spleen and persistent pain; when the prognosis is favorable. Unrelieved by surgical treatment the cyst itself, during long periods may not threaten life; it may, however, per- forate into some one of the surrounding viscera and thus lead to serious complications and death. In rare cases sloughing and hemorrhage have followed and have caused death. Omental, mesenteric and peritoneal hydatids present palpable tumors which are all operable and offer a good prognosis, better when the cyst is not broken during its manipulation thus preventing poisoning. Hydatid Disease of the Brain.—Intra-cranial hydatids often grow to DISEASES DUE TO METAZOAN PARASITES 309 enormous size without causing symptoms. The cyst may be found either large or small in any part of the brain. Naturally its symptoms and prog- nosis in most cases are those of brain tumor and depend upon its size and location. Occasionally there are multiple hydatids in the brain. The cerebral hydatid is fourteen times as frequent as is the cerebellar (Sterling and Verco) growth. Epileptic convulsions are a frequent accompaniment of hydatids of the brain; most patients die during an epileptic fit; they may fall into coma after a period of meningeal symptoms; they may live during a long period of paralysis, or, as often happens, they die of intercurrent disease. Superficial hydatid cysts of the brain when localized by the diagnos- tician and attacked surgically, offer a fair chance of recovery. Hydatids in the remaining organs of the body are so rare as to* re- quire no further consideration. References Allbutt & Rolleston. 2. ed., ii, 1,014- Askanazy.

Barring occasional febrile move- ment, irritability, petulance, rectal uneasiness, rarely reflex disturbances, such as convulsions, we have never found either of these round worms the cause of disease in our practice. Only rarely are distressing condi- tions caused by the wandering of the ascaris. Worms are vomited; at times they enter the postnasal space from the esophagus, the eustachian tube or the larynx. Asphyxia and gangrene of the lung are recorded among the accidents due to the wanderings of the worm (Osier);. They may find their way to the liver, causing abscess, or to the bile ducts. (c) Ankylostomiasis ( Uncinariasis, Hookworm Disease, Miner’s Anemia, Egyptian Chlorosis, Dochmiose, Ankilostomoanemia, Tunnel Disease) Ankylostomiasis is a form of progressive and grave anemia with symp- toms referable to the gastro-intestinal tract and nervous system due to the Ankylostoma duodenale, originally described and recognized by Dubini in 1843. The Papyrus Ebers, according to Scheuthauer and Joachim, about 3,550 years B. C. mentions a disease due to a worm Heltu ‘which caused all of the symptoms of ankylostomiasis and has been known by the Egyptians from times immemorial. It is questionable whether the disease mentioned in the papyrus Ebers was identical with the present day hook-worm dis- ease ; Oefele denies it. Occurrence.—The disease caused by the worm prevails in tropical and subtropical countries. On the Continent of Europe it is found among the miners of Erance, Austria, Hungary, Germany, Switzerland and Bel- gium. In England, the disease prevails among the Cornish miners (Boy- cott and Haldane) (Montgomery). In Egypt the disease is found among the natives and the Indian coolies. The credit for our exact knowledge of the hook-worm and its resulting disease as found in the United States belongs entirely to C. W. Stiles, whose conclusions are now fully accepted by the profession. (Full references to the contributions made by Stiles are given in the bibliography at the end of this chapter.) The Infection.—The worm which causes the disease in the United States, it is now believed, does not belong to the Uncinaria but is given the name of the “Hew World Hook-worm or Necator americanus of Stiles, in contra-distinction to the “old world worm” or Ankylostoma duodenale. In- fection is due to the development of the eggs, millions of which are passed with each stool of the infected patient. These develop in feces mixed with the earth or sand at a temperature of from 70° to 90° F. The human being is infected as a rule through the skin; from the fingers through the DISEASES DUE TO METAZOAK PARASITES 311 mouth, which latter method is unusual. Loos has demonstrated the course followed by the larvse after entering the skin. They pass from the veins to the heart, into the lungs, through the pulmonary vessels, into the bronchi, and from there into the post-pharyngeal space to the esophagus and out through the stomach and intestinal tract. The lack of caution in caring for the infected stools is the paramount factor in the spreading of the disease. The “ground itch” is prevalent among 90 per cent of those infected according to Ashford and King (H. W.). Clinical Manifestations.—The leading clinical manifestations of hook- worm disease include a period of malaise with increasing languor, after which gastro-intestinal symptoms predominate with circulatory and respira- tory disturbances. The anemia is characteristic and is probably due more to the hemolytic action of the poison elaborated by the worm than by the direct loss of blood. The red blood corpuscles are reduced in proportion to the severity of the anemia from 1/4 to 1/10, the hemoglobin falls to 15 and 20 per cent in grave cases. It will be noticed that the color index continues high. Eosinopliilia is a constant attendant, reaching as high as 40 per cent of all leukocytes in the more pronounced cases. Leukocy- tosis is rarely marked. The complication of ankylostomiasis by pneumonia at once reduces the existing eosinopliilia. Leichtenstern found a drop of eosinophils to 6-7 per cent from 72 per cent. Warburg from 65 per cent to 0 and a return of the eosinopliilia with the recovery of the patient. Acute sepsis has the same effect. Sufferers from the disease are lethargic; children continue dull and apathetic, they remain undersized, drag themselves about shiftlessly, and fail to attain their growth until years after puberty. The graver cases which continue unrelieved by treatment show the marked anemia, the faulty development, asthenia, dilated heart, respiratory embarrassment, the mental sluggishness, the skin changes of itch and the infected stools. Incidence and Prognosis.—The incidence and prognosis of the disease have been enormously influenced by the education of the people which has resulted in concerted action to destroy the worm by removing the baneful conditions which make its multiplication possible and inducing the infected to care for themselves and to take advantage of specific treat- ment. The wearing of shoes to protect against infection through the skin has also been a powerful prophylactic factor. Barring cases which have advanced to threatening asthenia with heart insufficiency and a blood condition which is extreme, the prognosis of treated cases is surprisingly good. In some cases there are relapses. The return to full health is often slow but certain. The blood is regenerated after varying periods. 312 SPECIFIC INFECTIOUS DISEASES References Ashford & King (H.

It is a small worm of peculiar build, with marked differences in the anterior and posterior parts of the body, being thin anteriorly and broad posteriorly; its length is from 4 to 5 cm.; the female is longer than the male. The worm is not common in the United States but is frequent on the Continent of Europe. Hundreds of worms may be present without causing symptoms or materially interfering with the health of the host. The prognosis is always good. (e) Trichinosis Trichinosis is an infection of man due to the eating of imperfectly cooked or raw pork or ham which holds in its muscle the larval or encysted form of the Trichina spiralis. The worm is a nematode, unusually resistant and infests the muscular tissue of man, giving rise to charac- teristic subjective and constitutional symptoms with a blood picture in- cluding eosinophilia. (Thayer and Brown.) The Infection.—In the process of digestion the ingested larvae are freed in the stomach; in 3 days the period of sexual activity begins in the intes- tinal tract. The sexes unite in the intestines and innumerable embryos are produced within from 1 to 9 days. The embryonic worm does not penetrate the intestinal wall as was formerly supposed, but the female DISEASES DUE TO METAZOAN PARASITES 313 worm finds her way from the muscular and mucous coat of the intestine by way of the lymphatics, the veins and the blood stream secondarily, to the striped muscles (mainly) of the host, in which they are easily recog- nized when bits of the muscle tissue are harpooned and examined micro- scopically. In occasional instances the worm is encapsulated within about 6 weeks. Nature finally provides the encapsulated worm with a dense fibrous membrane which, within from 4 to 6 months, becomes cal- carious. In occasional cases, coincident with trichinosis, there are sec- ondary infections which materially modify the course and the prognosis of the disease (cocci, etc.). The encysted worm may live undisturbed during many years. Symptoms.—In most cases the infection is promptly followed by a stage of intestinal symptoms. These symptoms vary in accordance with the severity of the infection. In the severer cases, diarrhea, colic and vomit- ing are in the ascendency; all severe and exhausting. The mild cases may present none of these intestinal manifestations; on the other hand, there are severe cases in which the early symptoms of intestinal invasion are not outspoken at once, but these symptoms gradually develop or may he entirely absent. In all cases the prognosis is largely influenced by the number of the invading worms. Grave symptoms often follow before the embryonic worm has had time to settle in the muscular tissues of the patient. These symptoms, including great exhaustion and muscular weakness, are due to the poisoning influence of the worm (metabolic products of the trichinse themselves), for it has been proved experimentally that the blood serum of the trichinous animal is poisonous early, i. e., before muscle invasion. The prognosis, after muscular invasion, depends, besides, upon the resistance of the patient, the degree of constitutional disturbance, the ex- tent and location of the muscular invasion, the severity of the nervous manifestations and the gravity of the complications. Marked muscular rigidity and severe and widely spread muscular pains, with high fever, rapid pulse, albuminuria, diarrhea, delirium, the Kernig symptom following the period of intestinal symptoms, and evi- dences of edema of the glottis are among the more serious manifestations of trichinosis and demand a guarded prognosis. Involvement of the respiratory muscles, including invasion of the muscles of the larynx and diaphragm, associated with hoarseness and dyspnea, at times marked air hunger and cyanosis, is always alarming and is present in the graver forms of the disease and demands great caution in offering a forecast. When the constitutional symptoms include a long-continued typhoid condition with increasing weakness and emaciation, and an unfavorable blood picture, the prognosis remains doubtful and grave during several days. 314 SPECIFIC INFECTIOUS DISEASES The presence of albuminuria with other favorable symptoms is not of serious import. The presence and persistence of the Diazo-reaction does not influence prognosis. Bronchitis is a frequent and not a serious complication when limited; when the smaller tubes are invaded and there is also respiratory embar- rassment due to muscle disturbance (diaphragm, etc.), the bronchial catarrh may add an element of danger and cloud the prognosis. When myocardial weakness is present sufficient to cause edema of the extremities and other evidences of heart insufficiency, unless the disease has run its course or the heart responds to treatment, the outlook is exceedingly grave. Pneumonia, whether lobar or lobular, is always a grave complication; this is the rule in those cases in which respiratory symptoms due to trichinosis already exist and the dyspnea is associated with a feeble and non-dependable circulation. Limited peripheral thrombosis, when without other serious complica- tion, adds but slight danger to the disease. Cerebral thrombosis or throm- bosis of other vital organs is almost always unfavorable. In the chronic cases, those dragging along during several months, the development of bed-sores retards recovery and may lead to secondary infection. Enlargement of the spleen is in all probability due to secondary infec- tion, its disappearance is always to he interpreted favorably. During the first two w7eeks of the disease the spleen offers no prognostic data. Blood.—The blood shows characteristic changes which demand its close inspection for diagnostic and prognostic purposes. The red blood corpuscles show no marked change. Leukocytosis in mild cases is not excessive. The more severe cases show a decided tendency toward poly- morphonuclear leukocytosis. There is an enormous increase of eosino- phils with displacement of neutrophils. This may mount to from 30 to 60 per cent. (Thayer and Brown.) Staubli and Hegar claim that in spite of the relative reduction of the neutrophilic leukocytes there is an absolute and marked, increase of these, sometimes reaching as high as three times the normal count and therefore the high eosinophilia is not present at the expense of the neutrophils. It has been shown that as a rule the graver forms of the disease are associated with the highest eosin- ophilic counts. Schleip found percentages varying in accordance with the gravity of the disease, between 20 and 62 per cent. Kerr found 86 per cent in one of his cases. Thayer and Brown found 16,000 eosinophils (in 1 c. mm.) as against the normal count of 150-250. Moderate eosinophilia may persist long after convalescence, and in occasional severe forms of the disease may be limited and insignificant. Improvement usually follows the appearance of moderate lymphocytosis DISEASES DUE TO METAZOAN* PARASITES 315 and a striking increase in the number of blood-platelets. Eosinophilia is not likely to be marked during the stage of intestinal invasion, but depend- ing upon the metabolic products of the Trichina spiralis, is coincident with the deposit of the worm in the muscles of the body. The duration of mild cases is from 16 to 35 days. The severe infec- tions may continue during several months; these cases are followed by a slow convalescence, long periods of muscular weakness, asthenia, myalgic pains and occasional intestinal anomalies. Most deaths occur between the third and fifth week of the disease; in over 60 per cent of these, there is invasion of the respiratory muscles and often secondary bronchopneumonia. Owing to a guarded quarantine and the thorough examination of pork and its products, trichinosis is at present comparatively infrequent. Mortality.—The mortality varies in different epidemics and is influ- enced by the factors already considered. I have in my experience found the mortality of our hospital cases low. The average mortality may be placed between 4 and 30 per cent. Children bear trichinosis much better than do adults. It must be remembered that rheumatic pains and vague symptoms may continue during many years. Kerr. Lommel, Mohr & Staehelin, 1911, i, 1022. Schleip. Deutsch. Arch. f. klin. Med., 1904, Bd. Ixxx.

References (f) Filariasis There are a number of round worms belonging to the family Filaridce, which infect the blood of man or other portions of the body, discovered by Wucherer, 1866, in Bahia and by Lewis in 1872 (Filaria sanguinis Jiominis), which give rise to symptoms. Most of these worms pass during the night from the lymphatics into the blood stream. The leading symp- toms caused by these nematodes are hematuria, chyluria, elephantiasis, lymph-scrotum, chylous ascites and elephantoid fever. The blood filarhe which interest us are: a. Filaria Bancrofti (Cobold, 1877). b. Filaria diurna (Manson, 1891). c. Filaria perstans (Manson, J891). The filaria of Bancroft causes hematocyturia and the lymph-scrotum. The blood shows the presence of the worms during the sleeping hours, 316 SPECIFIC INFECTIOUS DISEASES whether the patient sleeps during the day or night. The blocking of the lymph-channels causes most of the conditions already mentioned and elephantiasis. All of these conditions may persist during many years without causing marked inconvenience or affecting health. The lymph-scrotum may lead to great inconvenience because of its size, the thickening of the skin and the change in the lymphatics, but it is not directly dangerous to life. There are cases of fiiariasis in which there are a number of weeks or months, occasionally years, of lymphangitis with erysipelatous inflamma- tion and fever. (Elephantoid fever.) Abscesses may develop in these cases; surgical treatment has relieved some of them. The prognosis of scrotal elephantiasis after amputation is good; occa- sionally recurrences have followed cases in which the incision was made in diseased tissue. In women, the infection may produce elephantiasis of the external genitals, and the mammary glands of both sexes may show enormous enlargements. With persistence of chyluria and hematochyluria patients may live undisturbed during many years. Occasionally anemia causes weakness and threatens life. Only rarely does the patient die without intercurrent disease. Spontaneous cure can only occur in the most favorable surroundings where fresh infection can be prevented. 3. Trematodes {Bilharzia hematobia—Bilharz) The blood fluke (Schistosomum hematobium) or Bilharzia hema- tobia was first recognized by Bilharz in 1851. The male worm is one- half inch long, the female three-quarter inch. The adult worm carries the female in a curved canal (gynecophoric canal). The worm is found mainly in Northern and Southern Africa, in Persia, Arabia and along the west coast of India. Griesinger in 1851 called attention to the fre- quency of the worm in Egypt, where in 363 autopsies bilharzise were found in 117. The leading inconveniences caused by these blood flukes are hemdr turia, bladder and kidney irritability, consecutive cystitis and secondary anemia. There are in some cases rectal and vaginal disturbances leading to tenesmus and dysenteric symptoms and chronic vaginitis, due to direct local infection. Among the complications which materially influence prognosis are profuse hematuria with secondary anemia, pyelitis, nephritis, renal and bladder calculosis, dysentery, asthenia and marasmus. In some cases the INFECTIONS OF UNKNOWN ORIGIN 317 low hemoglobin content of the blood is characteristic with a relatively high red blood corpuscle count (oligochromemia). There is some leukocytosis (40 per cent) (Grawitz). Lymphocytes and eosinophils reach as high as 53 per cent. The gravest forms are found in men oftener than in women. Multiple urinary fistulas often complicate bilharziasis very materially and unless relieved may lead to septic conditions or tend to drain and exhaust the patient. Even the grave forms of bilharziasis do not run an acute course but in the overwhelming number of cases are chronic, cover- ing years, and patients may die of intercurrent disease besides the com- plications already mentioned. Liver flukes are rare in America or on the Continent of Europe. In Japan, China and India, they are found infecting the bile passages, causing enlargement of the liver, icterus, pain, gastro-intestinal symptoms and in the terminal stages dropsies and ascites with marked anemia. The disease is chronic and usually causes death. References Grawitz. Klin. Path, des Blutes. 1911. Gresinger. Arch. f. phys. Heilk., 1854, 554. E. Infections of Unknown and Doubtful Origin I. Poliomyelitis (Infantile Paralysis, Heine-Medin Disease: 1840-1887) 1. Acute Anterior Poliomyelitis The revelations of the past fifty years have led the pathologist and clinician to positive views concerning the various forms of poliomyelitis, and justify a definition which proves the infection to be far-reaching in its effects, by no means limited to the anterior multipolar cells in the cord, in which by predilection, it is true, the greater changes are pro- duced and are promptly recognized. To the reader who is eager to study the history of the disease, we would commend the references ap- pended to this chapter. Our present conception of infantile paralysis justifies the conclusion that it is an infectious disease of early life, as a rule communicable. In all probability it is due to a filterable organism which is ultramicroscopic, causing a short period of indefinite symptoms followed by the prompt development of paralysis in most cases, and other features of invasion 318 SPECIFIC INFECTIOUS DISEASES of the nervous system; these depend entirely upon the location and extent of the lesions. The clinical types are numerous and well defined, making localization and accurate pathologic conclusions possible. It is not at all unlikely that the minute organisms found by Flexner and Noguchi, consisting of globoid bodies 0.15 micron to 0.3 micron in diameter, and arranged in pairs, chains or masses, are the true cause of the disease. This question is still sub judice. Flexner and Noguchi have grown the cocci in human ascitic fluid. They pass through the Berkefeld filter, are capable of reproducing the disease in the monkey, and from these they can be again recovered in pure culture. The organ- ism is anaerobic. When the clinician for either diagnostic or prognostic purposes con- siders the underlying pathologic changes of anterior poliomyelitis, he must remember that he is dealing with an infection in which all structures of the nervous system may be involved, with a strong preference for the motor neuron. Hence to focus our attention upon the structures most prominently included in the pathologic picture, we consider the various manifestations of the disease as expressions of either neuritis, acute ante- rior poliomyelitis, meningitis, meningomyelitis or poliomveloencephalitis. Occasionally the paralysis is of the Landry type, to which we will again refer. The above conclusions are corroborated by a study of the epoch- producing contributions to the literature of this subject by Heine, Medin, Wickman, Strumpell, P>ergenholtz, Flexner and Homer. Clinical and pathological material thoroughly studied, is convincing. The fact which we wish to impress is that so-called anterior poliomyelitis can no longer be considered to be a disease of the anterior horns alone, but that its pathology and symptomatology may include changes in the central and peripheral nervous system as well as in the membranes of the cord and brain, in a large number of cases. The disease is now more frequent than ever before, and is also spread over a larger territory. Rosenau in the followung table shows the num- ber of outbreaks and the number of cases from 1880-1910: Cases. Outbreaks. Average Number of Cases per Outbreak. 1880-1884 23 2 11.5 1885-1889 93 7 13 1890-1894 151 4 38 1895-1899 345 23 15 1900-1904.. . 349 9 39 1905-1909 8,054 25 322 Of the 8,054 cases reported between 1905 and 1909, 5,514 or about five- sevenths were found in the United States, INFECTIONS OF UNKNOWN ORIGIN 319 The cases have been more severe during the past few years than ever before, and in certain sections the number of ascending paralyses in adults, of the Landry type, have been correspondingly frequent and fatal, A further interesting feature is the greater fatality and relative frequency in the country districts and small villages than in the crowded cities. It has been my experience that outlying districts of cities, and sparsely settled sections, offer more cases than do central and thickly populated centers of cities. The majority of cases occur during the warmer months of the year; while sporadic cases are found regardless of season. It is not within the province of this work to consider the port of entry of the infecting agent: the consensus of opinion favors the nasopharyngeal route. We might add, however, that in our last case, which was severe and of the bulbar type, the disease followed within six days after the bite of a large horsefly, in a child four years of age. (See Rosenau.) It is further to he remembered that the disease may he conveyed by uhealthy carriers” who harbor infecting material in their nasal secretions —a fact which Flexner, Clark and Fraser have proved experimentally. There are no positive proofs that the disease is not directly contagious and in the present state of our knowledge, including the larger experi- ences of the Swedish observers, it is safe to so consider it. The period of incubation may be placed at from eight to ten days, with an average of seven days. The Prodromal Period.—The prodromal period offers practically no positive prognostic data. There are cases in which the pulse is rapid and feeble from the beginning and in which the disease proves grave, often of the bulbar type. The temperature and pulse taken together during the prodromal period are not to be relied upon for prognosis. Early involvement of the respiration, rapid and superficial breathing during this period is always significant and is found with the bulbar type of paralysis, or may be due to bronchopneumonia, which is a frequent cause of death. Gastrointestinal symptoms are among the most frequent accompani- ments of the first stage of the disease; they are controlled or yield spon- taneously in most cases. The blood examination in this stage may be of great diagnostic and prognostic value, for it shows marked leukopenia. The nervous manifestations of the prodromal stage include more or less somnolence without psychic disturbances. Drowsiness and stupor during the early stage of the disease are not of unfavorable significance, and are more favorable than alertness. This experience was confirmed by the results of the investigations made by Draper of the Rockefeller Institute. In very young children convulsions need not be interpreted as serious; often they are followed by the stage of paralysis and other symptoms, 320 SPECIFIC INFECTIOUS DISEASES which at once clear the horizon, making the diagnosis of the disease and its type possible, and often permitting of a tentative but not a positive prognosis. The pains and rigidity during the prodromal period are in proportion to the extent of the meningeal infiltration {leptomeningitis). Profuse perspiration is usually present in both severe and mild cases. It is impossible to gain accurate diagnostic or prognostic data during the early stage, for as Romer has well said, “the initial symptoms are not characteristic of any one type of disease, but they are conglomerate, with the possible prominene of one symptom referable either to the meninges, the gastro-intestinal tract, the respiratory organs; or the features of infill- enzal fever may predominate.” This period is usually short, from twelve hours to three to seven days, and is followed by the second stage, the stage of paralysis. Stage of Paralysis.—It is in the stage of paralysis that we recognize the nature and the type of the disease. The diagnosis cannot he positively made before the appearance of paralysis; during endemics it can only he suspected. We recognize the following types (Romer) : (a) Abortive (b) Spinal (c) Landry (d) Bulbar and pontine (e) Cerebral (f) Ataxic (g) Polyneuritic (h) Meningeal (a) Abortive Type.—Wickman’s statistics showed that of 1,028 cases thoroughly investigated by him, 157 were of this type (15.3 per cent). In these the prognosis is uniformly good. The toxins in this type do not attach the motor neuron nor the other central organs, and there is therefore no paralysis. The features which are prominent and yield after a few days are fever, pains in the head and back, tonsillar invasion, bronchitis and all of the other manifestations of the prodromal stage of the more severe cases. Edward Midler has described cases which offer a good prognosis, in which there are transitory paralyses of a single group of muscles, or there may be evanescent loss of the tendon reflexes. These he has characterized as “rudimentary poliomyelitis.” Midler places the incidence of the abortive types much higher than does Wickman. The former claims that during epidemics fifty per cent of all cases are of this type. My experi- ence proves that not all epidemics are alike in their virulence, and we have often found the coincidence of other acute infections with infan- INFECTIONS OF UNKNOWN ORIGIN 321 tile paralysis, which may have been considered abortive forms of the disease, and which may account for these varying conclusions. The larger number of abortive cases were found between the ninth and eleventh year, and during this period it will be noted from the study of Wickman’s tabulation, there are the fewest paralyses. (b) Spinal Type.—The spinal type is the most frequent of all forms. The paralyses are promptly evident “paralysis of the morning.” It is a complete motor paralysis. It soon proves to be flaccid; it may in some cases be extensive, involving all four extremities; it may be irregularly distributed, or it may from the beginning limit itself to one group of mus- cles. When two or more extremities are paralyzed, one extremity usually suffers more than do the others. The peroneal and quadriceps muscles are oftenest involved and permanently damaged. The cranial nerves includ- ing the ocular apparatus are only rarely involved; neither are there sphinc- ter paralyses. Sensory symptoms are due to associated cellular infiltra- tion of the meninges or the sensory tract, and are of short duration as a rule. Muscular atrophy is the fate of the muscles which remain paralyzed; with the flaccid paralysis the reaction of degeneration is present. The reaction of degeneration does not argue against the possibility of final restoration of function. Its persistence without motor improvement from six to twelve months after the onset, leaves but little hope for cure of the remnant of paralysis. With the atrophy of the paralyzed muscles there are trophic changes. The more developed the latter, including shortening of the affected ex- tremity, interference with the bone growth, marked and persisting lower- ing of the local temperature, the less favorable are the chances of restora- tion of function. Persistence of changed deep and superficial reflexes is unfavorable; in these cases the paralysis is likely to persist though the education of acces- sory muscles may prove of great assistance. Urinary retention during the prodromal period or following, is not, in the spinal form, an unfavorable symptom. We have found it both in the adult and in early life. In young boys (2-6 years) the urethra is not infrequently plugged with a dense phosphatic deposit, which is likely to recur, but is not unfavorable. Consecutive contractures remain and can only be overcome by ortho- pedic treatment. Equinovarus is the characteristic contracture which re- mains when the lower extremity is paralyzed. Resulting deformities such as kyphosis and scoliosis may often be prevented by proper treatment. When developed, they are likely to re- main, though in rare cases modern methods of mechanical treatment may result in marked improvement. In rare cases there may be exacerbations with fresh paralyses which are not usually extensive and are likely to dis- appear. 322 SPECIFIC INFECTIOUS DISEASES (c) Landry Type.—Our experience justifies the conclusion that Lan- dry’s ascending paralysis is identical with poliomyelitis, there being two forms of the disease. In the first form there is the characteristic and prompt development of ascending paralysis, usually beginning in the lower extremities, ascend- ing, and in the course of three to five days involving the diaphragm and respiratory muscles; finally there is the pneumogastric and glossopharyn- geal ; with spasm of the glottis, air hunger and death, usually before the end of the seventh day. The majority of patients die between the third and fifth day of the disease. Schluckpneumonia (aspiration) is not un- common. In the second form we have during the first twenty-four hours rec- ognized the ascending paralysis. The respiratory muscles are less in- volved; the upper extremities are paralyzed before the end of the fourth day; but the pneumogastric and glossopharyngeal are not involved in the process. The patient may live and continue paralyzed. Such cases are rare but they do occasionally present. We saw a student with this complex of symptoms ten years ago, who has since entered the practice of law in which he is making a brilliant success in spite of the motor paralysis of his four extremities, which has remained unchanged. (d) Bulbar and Pontine Type.—The bulbar and pontine form of poliomyelitis was described by Medin and includes the involvement of the cranial nerves in the motor paralysis. As a rule the bulbar and pontine invasion is coincident with the spinal form of the disease, as in a case (age four) at present under observation, in which there is paral- ysis of both lower extremities and both arms—the left greater than the right—and in which during the first four weeks the left facial nerve was also included. In this case the facial paralysis has disappeared (six months) with marked improvement of all other paralyses. The facial is oftener paralyzed than any of the other cranial nerves. The ahducens and motor oculi are rarely included. Our material includes one case in which the optic nerve was involved. (e) Cerebral Type (Polioencephalitis).—These forms of the disease are a mixture of poliomyelitis and encephalitis and were originally de- scribed in a brilliant article of Striimpell, whose observations have since been verified by Medin. The characteristic cerebral paralysis includes hemiplegia in children with marked trophic changes, developmental anom- alies, contractures, accompanied by the usual adduction of the arm, with flexed elbow and well marked clubfoot (pes equinovarus). The reflexes in children with these symptoms are likely to continue abolished; in the adult they may be present or exaggerated; Bahinski persists or may be absent. In children athetosis may finally develop. Cerebral polioencephalitis may involve the cerebellum and its paths. The paralyses due to this form of poliomyelitis may improve, but com- INFECTIONS OF UNKNOWN ORIGIN 323 plete return of function cannot be expected. The majority of these chil- dren remain bright, but go through life hemiplegics. (f) Ataxic Type.—Medin, Wickman, and Zappert observed symp- toms in some of their cases which after the prodromal period resembled Friedreich’s hereditary ataxia. In these cases the prognosis for full restoration of function is unfavorable. (g) Polyneuritic Type.—These cases present all of the features of multiple neuritis. They arise during epidemics of the more common forms of poliomyelitis, and are held by Medin to be due to the same virus which causes all other types. They are associated with sensory symp- toms and tender nerve trunks; there are often evidences of meningeal in- flammation, including the Kernig symptom. The prognosis of the poly- neuritic type of the disease is favorable, though recovery may be slow. (h) Meningitic Type.—In this form of the disease there are, during the early days, many of the symptoms of acute leptomeningitis arising in the midst of an epidemic of poliomyelitis, including the Kernig symp- tom. This is followed in most cases by well developed paralyses with the usual characteristics of infantile paralysis. ISTetter reports that twenty- nine per cent of his cases are of the meningitic type of the disease. General Considerations Lumbar Puncture.—In the fatal cases of Landry’s ascending 'polio- myelitis the fluid escapes under high pressure and contains albumin in appreciable quantity. There are no polymorphonuclear cells but the French have confirmed the observations made by some American observ- ers that there are a good number of lymphocytes present. In the usual forms of the disease the fluid escapes under moderate in- crease of pressure, the quantity of the fluid being increased; it is usu- ally clear, contains no microorganisms, and gives a negative Wassermann reaction. For both prognostic and diagnostic purposes it is of interest to note that while the withdrawn spinal fluid continues negative, the blood (as reported by Plaut and Schottmuller) is likely to give a posi- tive Wassermann reaction during the acute period, and becomes nega- tive at the end of four weeks—with the improvement of all symptoms. The globulin reaction is positive, according to the experience of most clinicians, though in the recently published work of Plaut it is claimed to be absent. Lmphocytes are present in the fully developed cases in the fluid. Electrical Reactions.—Oppenheim believes that the electrical response of the paralyzed muscles gives important prognostic information. Those muscles, he claims, in which the reaction to the faradic current is not entirely lost after the third week will be likely to recover full power ultimately. 324 SPECIFIC INFECTIOUS DISEASES Groups of muscles in which at the end of the first week of paralyses there is complete reaction of degeneration are not likely to recover in the majority of cases, though the prognosis is not had in all of these, as has already been indicated. We have seen full return of power with both complete and partial reaction of degeneration. Eckert believes that inability to move the toes is unfavorable for the full restitution of motor power in the paralyzed leg. Conclusions.—A study of the preceding pages must lead to the con- clusion that poliomyelitis is not an innoce?it disease; that deaths are not infrequent as the direct result of the infection—a fact which is not sur- prising in the light of our present conception of its pathology. The most convincing conclusions must rest on the study of a large number of cases cautiously investigated. This has been conscientiously done by Wick- man (Governmental investigation, 1905) in 1,028 cases. Of these 868 were paralyzed, 157 were abortive cases (15.3 per cent) and showed nr paralysis, or only transitory motor symptoms. Of the entire number 159 died (12.2 per cent). The average number of days these lived was fifteen. Following the cases paralyzed which finally died, we find that by adding these to the early deaths, the mortality of poliomyelitis was 16.7 per cent. The mortality varies in different epidemics from ten to forty- two per cent. The mortality as given by nine collective investigations (Romer, page 27) was between 10.8 per cent and 22.5 per cent. In the monkeys infected experimentally the mortality is very high, 75 to 76.4 per cent (Homer, Flexner and Lewis). Of Wickman’s 157 deaths, 14 died after the fifteenth day and 143 between the first and the fifteenth day. The following table (Wickman) proves that the fourth day claims the larger number of children (25.5 per cent).

In one case the father of nine children (all in the same house) contracted the disease without a single infection among the children. If children live beyond the 15th day the chances are that life will not be longer threatened. Children living beyond the 7th day are not likely to die. Twenty per cent of all paralyses recover fully, according to ISTeuroth. Wickman claims in children from 9-11 years, 48.4 per cent; after 11th year 32.2 per cent. Leegard’s figures show children to the 14th year, 30.4 per cent, and after the fourteenth year 22.2 per cent of recoveries from paralyses. We are justified in concluding that poliomyelitis leads to death in a larger number of cases than has been heretofore supposed; that the prognosis for life therefore must be guardedly given until beyond the 326 SPECIFIC INFECTIOUS DISEASES first week; that paralyses which are well developed may yield; that in the larger number of paralyses remnants will remain; that paralyses which persist beyond six to twelve months will prove to he permanent, with hut slight modification; that trophic changes persisting beyond twelve months remain uninfluenced; and that the most fatal form is the ascend- ing type with symptoms of Landry’s disease. So-called sporadic cases offer an excellent prognosis so far as the life of the patient is concerned, though the paralyses are more likely to be permanent than are those of the epidemic types. Cases of human and experimentally produced poliomyelitis prove that the length of the period of incubation offers no positive data for prognosis. 2. Chronic Poliomyelitis There are a number of cases of unknown origin occasionally following trauma, in which there is a subacute or chronic course with paralysis, closely resembling the spinal type of the acute disease. These cases are found in adults without the acute period of the epidemic forms and re- semble, when fully developed, the spinal type of muscular atrophy. They ditfer from progressive muscular atrophy because of the early paralysis and the atrophy which follows it. There may he exacerbations during which further paralysis develops, involving separate groups of muscles in which atrophy follows, with the flaccid paralysis. There is loss of reflexes and the reaction of degeneration. In occasional cases there may he marked improvement of all symp- toms. In a number of cases the exacerbations lead to progression of the atrophy, and with ascending symptoms and increasing weakness the pa- tient dies. These cases represent degenerative processes in the anterior horns, are often difficult to differentiate from progressive muscular atrophy, though as already mentioned, the early flaccid paralysis offers a differ- ential feafure. The atrophic changes are secondary, never primary. The lower extremities are usually involved first, though there may he mono- plegia, and later extension to other parts. The prognosis so far as life is concerned is less favorable than pro- gressive muscular atrophy, for the disease when progressive, ends fatally in from one to four years.

Scharlach) Scarlet fever is an acute infectious contagious disease, of unknown ori- gin, and of early life, characterized by fever, a far-reaching (scarlatinal) erythematous eruption, usually followed by desquamation and associated with throat complications of varying intensity, lymphatic enlargements and a strong tendency to sequelae in which the kidney, heart and joints may suffer serious damage. Children between 3 and 8 years of age are most disposed to scarlet fever; resistance seems to increase with increasing years. 328 SPECIFIC INFECTIOUS DISEASES In considering prophylaxis and prognosis, let it be remembered that the disease is contagious until the end of desquamation and one or two days before the outspoken symptoms of the disease. The corpse also holds and spreads the infection. The so-called “mild scarlet fever” may spread the infection and cause malignant disease in others. There are cases of scar- let fever without rash and with slight tonsillitis. It is exceedingly diffi- cult, in fact impossible, to offer any forecast of value during the early days of the disease, save in those cases which may be recognized at once as malignant, in which the duration is short and death prompt, often before the rash has appeared. There are so many and such serious complications which may influence the course of scarlet fever, whether the initial symp- toms are mild or severe, that it is never wise or safe to offer a forecast which commits the physician. Cases beginning with mild symptoms may be finally complicated with serious organic diseases of vital organs, while it is not at all uncommon to find those with alarming symptoms during the first five or six days of the disease march to complete recovery without an untoward incident. It is safe to consider those cases gravest, in which, during the period of invasion, there are marked cerebral symptoms, much vomiting, rapid pulse, high temperature and suppressed urine with albu- min in the little that is voided. Occasionally a case presents with symptoms so grave during the period of invasion, including those of profound and sudden sepsis, with immediate heart weakness, that death results before the appearance of the rash. These cases are not so frequent as formerly; it is a question whether the nature of the infection has not been influenced favorably by some un- known factor, for those who practised during the dark days of “malignant scarlet” and “masked scarlet fever” have lived to repeat these experiences only at rare and long intervals. Those were the days when entire families of children were stricken and died within twenty-four hours. In Central Yew York thirty years ago these experiences were frequent; I know of no repetition within the last twenty years in my own or in the practices of my colleagues, though now as before it is clear that the mortality varies in different epidemics and in different countries from 3 to 50 per cent. The highest mortality has been found during October and the winter months. The depth of color of the eruption varies, hut experience teaches that early mottling of the skin, cyanosis, purple-tinted, purpuric, or hem- orrhagic eruptions are strongly suggestive of severe infection, offering unfavorable prognosis in direct proportion to the degree of myocardial weakness. Widespread deposit on tonsils, pharyngeal wall and uvula, membranous in character, diphtheritic or streptococcic, is proof of mixed infection, and should lead to a guarded prognosis. Considerable involvement of the cervical lymphatics, with widespread angina, is found with the more severe infections, and should be given considerable weight in offering a forecast. INFECTIOUS OF UNKNOWN ORIGIN 329 If with pharyngeal and cervical invasion the nasal mucosa is also in- volved, and the symptoms of general infection manifest, more particularly, if the heart is showing evidences of added burden, the prognosis becomes grave. These cases are usually diphtheritic and reference to them will he repeated. Termination of the febrile period by crisis is in the majority of cases favorable. What complications may follow in any of these cases no diagnostician can foresee. Increase of symptoms, including great unrest, somnolence, delirium, persistent vomiting, between the second and fourth days of the disease, with deepening color of the eruption, cyanosis, with or without tonsillar change, but with increasing rapidity of the heart action and dila- tation of ventricles is of grave import (Toxic scarlatina) (Schick). Diphtheritic Infection.—Necrosis, sloughing of tonsillar tissue with symptoms of grave diphtheritic infection (positive bacteriologic diagno- sis), between the 3-5 days of the disease, often with middle ear and nasal invasion, is found in the graver forms of the disease. If the sloughing is deep, and, as individual sloughs are cast off, there is no tendency to heal, the prognosis is more serious than in those cases in which, as often hap- pens, the slough (i. e., process of necrobiosis) is superficial with prompt healing, decrease in size of lymphatics and constitutional disturbances. Persistent high temperature without decided fall during the morning hours with sloughing, is indicative of deep infection and is serious. The depth and extent of destruction of pharyngeal tissue are impor- tant factors in prognosis. Extension to the larynx with widespread phar- yngeal destruction is serious, as is also laryngeal croup. The lower the temperature on the second day of the disease (eruptive period) in cases remaining uncomplicated, the more favorable is the prognosis. The Ear.—The ear offers important data for prognosis; its early infection in cases with symptoms of spreading infection (particularly diph- theria) and associated deep necrosis of tissues, is always serious. Acute otitis causes increase of temperature, interferes materially with nutrition and may lead to acute meningitis from mastoid invasion or may he the cause of sinus thrombosis, with its serious accompaniments. Chronic changes may follow early or late otitis media suppurativa, causing deafness, spreading infection, pyogenic disease of the brain, months and years after the initial disease. Chronic mastoiditis with latent abscess continues to he a menace and may remain unrecognized, to he suddenly lighted into activity, and may cause meningitis and death. Otitis suppurativa may spread infection to distant organs; the peri- cardium, endocardium and joints have been infected by pus producing organisms from this source. The Respiratory Organs.—Pneumonia (staphylococcus or streptococ- cus) secondary to otitis has followed with serious results in many cases. 330 SPECIFIC INFECTIOUS DISEASES Purulent 'pleurisy (empyema) dependent on otitis is always a grave complication. A very large number of middle ear suppurations are late complica- tions, often during convalescence, which, when recognized early and rad- ically treated, offer a very favorable prognosis. The Blood.—There is a moderate leukocytosis and eosinophilia with scarlet fever; a decided drop or absence of the latter is unfavorable. Keckzeh reports that leukocytosis and eosinophilia are at their height as the eruption begins to fade. The Cardiovascular System.—Children bear a rapid pulse well during the early stages of scarlet fever, hence rapid heart action without evidences of dilatation or myocardial weakness, secondary cyanosis or mottling of the skin, is not of itself serious. Persistently rapid heart action (140 and above) is usually evidence of profound infection and grave. Small, thready, rapid pulse, above 150 on the first day, in children, with other grave symptoms is always ominous. Acute myocardial degeneration with dilatation is promptly shown in symptoms of circulatory insufficiency, congested skin, cyanosis, dyspnea, and is among the serious complications whenever present. Endocarditis (acute) and pericarditis are frequently associated with myocardial degen- eration. Scarlatinal endocarditis is, next to rheumatism, the most frequent cause of chronic valvular disease. When acute endocarditis and nephritis are co-existent, as often happens, the prognosis is less favorable than if but one of these complications exists. Many cases, however, recover and it is surprising to find among these but scant remnant of disease in either heart or kidney if patients are cautiously watched and scientifically treated. To improve the chances of scarlet fever patients, the endocardium demands the same watchful care in this disease as in rheumatism. Often an endo- carditis may run its course ending in serious damage without subjective symptoms; physical signs, however, prove its presence in most cases early, hence the prognosis is improved in proportion to the early diagnosis and subsequent care given these patients. It must be remembered that, in rare cases, post-scarlatinal endocarditis may develop without subjective symp- toms and may lead to permanently damaged valves. Septic or malignant endocarditis may complicate otitis, diphtheria or other mixed infections with scarletina and always ends fatally. Irregularities of the heart, erratic behavior, at times surprisingly slow hearts alternating with sudden acceleration, are complications present dur- ing convalescence which are relieved by continued rest and abundant time. Increasing systolic blood pressure with or without albuminuria during the first 2 or 3 weeks of scarlet fever, indicates obstruction in the renal circuit—hence nephritis. It is compensatory, and should be accepted as an evidence of Nature’s effort to assist in the cure. When dilatation fol- INFECTIOUS OF UNKNOWN ORIGIN 331 lows this condition, slight and insufficient hypertrophy, diffuse area of car- diac impulse, the prognosis is less favorable. Increased systolic blood pressure may be present during the early days of albuminuria, before there are other evidences of nephritis, and is likely to be the first suggestion of that complication. The Kidneys.—Acute nephritis complicates one-seventh (1/7) of all cases of scarlet fever, and is a frequent cause of chronic kidney disease (interstitial and parenchymatous). Recovery is the rule in the majority of cases of scarlatinal nephritis, though it often leads to death. True scarlatinal nephritis is not likely to develop before the third week, and should not be confounded with the febrile albuminuria of the disease. It may begin to show itself as late as the 6th or 8th week. The greatest source of danger is uremia. + Uremic poisoning, usually arising suddenly, may be found with the mildest as well as the more severe nephritides. As a rule the complica- tion may be expected if there have been the usual premonitory symptoms of uremic poisoning, including vomiting, headache, markedly reduced uri- nary secretions, slow pulse, with increased blood pressure. While uremia is a serious complication, the prognosis is not entirely bad and cases which appear serious, in which the coma and other evidences of surcharged blood are threatening, may fully recover. It is surprising to note how long chil- dren bear uremic poisoning in individual cases, and how completely they lift themselves out of it. No case of uremia in a child is so severe that it may not recover. I have seen children profoundly uremic with complete suppression of urine during 2, 3 and even 4 days, recover with return to normal kidney function and final restoration of normal kidney tissue, so far as I could tell from the subsequent histories of these cases. Patholo- gists and clinicians have repeatedly proved that two-thirds (2/3) or even more of our total kidney substance can be spared without serious incon- venience (Bradford). I have already referred to the association of heart and kidney lesions. Nephritis is a frequent cause of cardiac asthenia, leading to severe dyspnea, cyanosis and edema of the lungs. Endo- and pericarditis with nephritis are always serious. Dropsies, particularly hydropericardium and single or double hydrothorax, are complications due to nephritis, of grave significance. The prognosis in these cases should not be given as positively bad, for recovery does take place occasionally in spite of multiple complications. . The height of the fever in scarlatinal nephritis when the symptoms are acute does not offer much of prognostic value. I have seen many cases in which the temperature for several days has continued high, which finally proved tractable and ran a short course. In my practice I have found the quantity of urine secreted and the heart condition to offer most reliable prognostic data. Until the quantity of urine has increased and its color cleared, with reduction of casts and blood and a fair urea output, no positive prognosis can be given. Even 332 SPECIFIC INFECTIOUS DISEASES in these cases we must leave a loop-hole in our prognosis for occasionally, for some reason, there is sudden suppression and. a return of uremic symptoms. If with uremia or nephrkis the heart fails to respond to treatment, if the pulse grows more tense and has periods of flabbiness and continues rapid, a guarded prognosis must be given, v Increasing anemia with eye symptoms, and persistence of edema, are evidences of extensive and obstinate kidney lesions, and influence prognosis accordingly, worse with cardiac instability. Cases of nephritis which may he characterized as almost completely unon-albuminuric>'> in which a trace of albumin and fe\y casts are found at long intervals, usually on arising in the morning (orthostatic albumin- uria), yield to rest and treatment. When these remain unrecognized or untreated they are likely to be followed by chronic nephritis. The duration of average nephritis with scarlet fever is from 2 to 4 weeks. Arthritis.—Non-suppurative polyarthritis complicates scarlet fever in 6 per cent of cases. Developing during the second week usually or later as a rule it leads to recovery without damaged joints or endocardium. Occa- sionally endocarditis with positive physical signs develops, and almost all of these recover with but slight damage. In cases of scarlatinal arthritis rapid pulse and high temperature are not necessarily serious. In most cases both are high and yet recovery is the rule. Adenitis.—Most cases of suppurative adenitis lead to full recovery. The types of diphtheritic and gangrenous adenitis complicating mixed in- fection (diphtheria, etc.), at the height of the disease, have been mentioned above and are always part of a serious process. Adenitis with nephritis is a combination of serious moment though the larger number of these finally recover. Resume.—Pneumonia (post-scarlatinal) is often associated with em- pyema and offers a grave prognosis. It may be accepted as a rule for the prognosis of scarlet fever that, I. Added infection of any kind adds to the danger of the original disease. II. ZTSTo disease requires such a long period of observation of the kid- ney and the cardio-vascular system. Finally, to classify systematically cases for prognosis, we accept Moser's division. I. and II.—Favorable cases. III. Doubtful cases. IV. Hopeless cases. Division I.—Includes cases without serious symptoms, reasonable tem- perature. Few or no pharyngeal symptoms, good general condition. Division II.—Includes moderate intensity of symptoms. But one or INFECTIONS OF UNKNOWN ORIGIN 333 two symptoms in the ascendancy. Moderate pharyngeal invasion. No suppurative otitis media. Moderate erythematous eruption. No heart weakness, no cyanosis. Fairly high temperature and pulse of good quality. Divisions III. and IV.—Include the severe cases, grave, toxic and in- fectious forms (diphtheritic) above described, usually in children between the 1st and 4th year of life. Mosers.

Smallpox {Variola, Ger. Blattern, Fr. Petite verole, It. Vaiuolo) Smallpox is an eruptive disease of unknown origin, epidemic or en- demic, probably due to ultramicroscopic life, possibly of protozoic origin (Cytoryctes variolse), and associated with skin lesions, invasion of mucous membranes, and constitutional disturbances. Historical Data.—The disease was known long before the birth of Christ; it raged in China and India, and was brought to Egypt and the continent of Europe during the sixth century. Until the sixteenth century the disease remained in Southern Europe, when Germany was invaded. It is strange that during the thirteenth century serious epidemics decimated England without reaching Northern Europe. During the sixteenth century it was brought to America by the Spaniards. In 1718, Lady Mary Wortley Montague introduced inoculation into Europe, but it was associated with such painful results that it failed to gain a foothold. In 1798 the illustrious Jenner gave to the world the epoch-producing discovery of vaccination which robbed smallpox of its terror, and will with proper supervision, strict quarantine, and concerted action of the lay world and the medical profession as represented in the modern Science and Art of Preventive Medicine, ultimately efface it. General Considerations.—The character of the vaccination, it is now universally conceded, affects prognosis. The non- and insufficiently vac- cinated are likely to suffer from the severer types of smallpox, either dis- crete or confluent. There seems in some families to be complete immunity to the disease, in some, repeated vaccinations remain negative. One colleague I have vac- cinated seventeen times without reaction. He has been in the midst of malignant smallpox, treated many cases, but has never contracted the disease. 334 SPECIFIC INFECTIOUS DISEASES One attach as a rule gives immunity, but there are so many exceptions, that the rule must be ignored if the public and the individual are to be protected. I have met several examples of mild first attacks of smallpox, in which second infections were severe and hemorrhagic. Reverse expe- riences I have also had. Epidemics vary in virulence and are likely to present many features in which they differ. Some may be characterized as malignant, others be- nign. It is a rule that the milder cases are'found at the close of the epi- demic. Ro age is exempt from the ravages of smallpox. It may attack the fetus in utero—usually with fatal result. Between the ages of one to forty the disease claims most of its victims. It is found in old age less frequently than during the active years of life. Prognosis of the disease in old age is bad. “The prognosis improves up to the age of ten, is more favorable until fifteen, and then gradually becomes less so, although the case mortality in discrete cases remains very small, at least until advanced old age” (White and Biernaski). The sexes are equally attacked and prog- nosis does not differ though pregnancy and miscarriage, resulting from smallpox of the fetus and the mother, add to the number of serious cases in women. It has been proved in all epidemics that smallpox in pregnant women is likely to be malignant and strikingly fatal. Pregnancy invites the disease. The disease is prone to attack negroes and the mortality among these, in the unvaccinated, is larger than among the whites. Stage of Incubation The stage of incubation (10 to 13 days) offers no symptoms nor note- worthy data of use for prognostic purposes. The stage of invasion may be either mild or severe. The rule that an invasion with mild symptoms argues in favor of a benign smallpox, has so many exceptions that these must he kept in mind and should protect the clinician against a positive prognosis too early. There have been within my experience a number of cases in which the symptoms of this stage were unusually mild and reassuring, in which during the period of eruption I faced malignant disease of the pustulo-hemorrhagic and hemorrhagic types. The severe backache (rachialgia) may be out of all proportion to the ultimate severity or benign nature of the disease. Profound cerebral invasion is occasionally met in non-malignant cases. As a rule it is safe to consider somnolence, coma, delirium and marked subsultus indicative of the more severe form of the disease. If these symp- toms are present early in the period of invasion, and are associated with Stage of Invasion INFECTIONS OF UNKNOWN ORIGIN 335 high temperature in the adult or child, if the pulse is correspondingly dis- turbed, irregular and erratic, rapid and small, we may expect a severe course of the disease. Hurried respiration during the period of invasion, with rapid pulse, high temperature and delirium, argue against mild small- pox. Marked enlargement of the spleen early is evidence of deep infection, and is of serious import though with “black smallpox” there is no enlarge- ment as a rule. Albuminuria, during invasion with nephritis, is always suggestive of great danger. Bashes or prodromal exanthemata (invasion) may differ. In some cases these are scarlatinal, in others they resemble the measle eruption and are likely to be macular. They are evanescent in almost all cases (12 to 24 hours) and do not lead to desquamation. The deep scarlatinal eruptions are more significant prognostically than the moderate erythematous rash or the measle-like eruption. Macular eruptions as a rule are favorable; the hemorrhagic prodromal eruption is likely to remain, and is always of serious significance. When both hemorrhagic and non-hemorrhagic macules are present during this period, the prognosis must be guardedly given, for while, this adds an element which may be interpreted as serious, a fair number of these cases recover. Convincing symptoms of use for prognosis are found toward the end of the period of invasion and the established stage of eruption. Stage of Eruption In connection with the study of the prognosis of smallpox it will he wise at this juncture to present the accepted classification of its varieties made clear as a rule, only during the stage of eruption. I. Variola vera. (a) Discrete smallpox. (b) Confluent smallpox. II. Variola hemorrhagica (hemorrhagic smallpox). (a) Purpura variolosa (black smallpox). (b) Variola hemorrhagica pustulosa (pustular hemorrhagic small- pox). III. Varioloid. IV. Variola without eruption. Pustulation.—Pustulation in the average case must be expected after vesiculation on the ninth day of the disease. A marked tendency early during pustulation to-confluence is found in the more severe forms of the disease. Pustulation, with limited eruption, few lesions of the mucous membranes and but few constitutional symptoms, is always favorable. Few pustules filled with blood—this probably due to self-inflicted trauma—are not significant. With the pustulo-hemorrhagic type of the disease, a few SPECIFIC INFECTIOUS DISEASES 336 bloody pustules do not influence the outcome. Many pustules—hemor- rhagic—with symptoms of pyemia, are usually indications of severe in- fection and make the prognosis grave. The earlier the hemorrhagic nature of the eruption in any form of the disease, the ivorse is the prognosis. Those cases justify a serious forecast in which there are hemorrhages into the shin early, and before pustulation or the pustulohemorrhagic con- dition is manifest. These cases are unusually virulent. The prognosis is grave if separate pustules, without hnown trauma fill with blood. The invasion of the mucous membranes (usually the mouth and throat, sometimes also the larynx, stomach, intestines, vulva, and rectum) is not as a rule of significance unless there are many pustules. If the invasion is far-reaching, the result is weakening and adds materially to the danger of the disease. Large hemorrhages from mucous membranes are serious and are usually associated with variola hemorrhagica. Temperature.—A decided fall of temperature shortly after the ap- pearance of the eruption, is always welcome and favorable. This is not at all unusual in cases which during the period of invasion, because of nerv- ous symptoms, were considered serious. In severe cases there is but little fall of temperature with the appearance of the eruption. The temperature promptly rises to the height of the period of invasion and even higher; cerebral and other grave symptoms persist. It is safe to interpret a de- cided drop of temperature as vesiculation begins, favorably, if it does not again mount to its former height. In severe cases the drop of tempera- ture even though appreciable, is of short duration; it is not likely however to be decided. Persisting high temperature during pustulation is pyemic or strepto- coccic in its nature, and when associated with far-reaching confluence, is serious. Blood.—During the stage of eruption the blood shows marhed leuko- cytosis (12,000 to 24,000) with lymphocytic increase. This begins on the fourth to the sixth day of the disease and may continue during several Aveeks or months after full recovery. Neutrophilic leukocytes are only relatively diminished. Macgrath, Brinkerhoff and Bancroft found in fatal cases and in those in which the skin lesions were severe and wide- spread, a decided lowering of the leukocytic count. These obseiwers also found increase of mononuclear lymphocytes. General Statement.—The general statement is justified that small-pox (I. Variola Vera) may be either benign or malignant, that the average mortality of all cases—and most of these are unvaccinated—varies in dif- ferent epidemics from 15 to 35 per cent. I. Variola vera (a) Discrete Smallpox.—Discrete smallpox has a mortality of 5 to 10 per cent. INFECTIONS OF UNKNOWN ORIGIN 337 (b) Confluent Smallpox.—The mortality of confluent smallpox is high: the greater the confluence, the worse the prognosis. If confluence is not spread over the back, the prognosis is correspondingly better. If con- fluence is limited to the face and extremities the prognosis is worse than in the discrete form, but better than if over the trunk at the same time. Infants below two years of age all die when the eruption is confluent. Be- tween two and five years of age one-fourth recover; after five years of age the mortality is lower; from ten to fourteen “the patient is more likely to recover than at any other age.” “After fifteen years of age the per- centage of deaths to recoveries increases steadily with advancing years” (MacCombie). Laryngeal and pulmonary complications with confluent smallpox, cellu- litis, and those unfavorable conditions mentioned under General Consid- erations add to the danger of confluence. (a) Purpura variolosa (Black Smallpox).—Purpura variolosa is al- most invariably fatal: recovery is so rare as to justify the gloomy forecast given. These patients die early in the disease, and as has already been mentioned, without demonstrable enlargement of the spleen—a fact of some prognostic value. (b) Variola hemorrhagica pustulosa (Pustular Hemorrhagic Small- pox).—In the preceding pages mention has been made of a number of conditions which materially modify the prognosis of these cases. It is not as fatal as black smallpox (Purpura variolosa) but is more frequent. The disease if fully developed is grave; the majority of patients die, usu- ally in collapse between the seventh and twelfth day of the disease. II. Variola hemorrhagica (Hemorrhagic Smallpox) III. Varioloid This is a modified form of smallpox. The overwhelming proportion of patients if inoculated, were probably not properly vaccinated—hence not entirely protected—or have gone beyond the period of immunity. The duration of all the periods of the disease is materially reduced; many features of variola vera are absent; fever disappears with the modified eruption and rarely returns: when it does, it is of short duration and due to absorption of pus during pustulation. Vesiculation and pustulation may not follow the formation of the papule; mucous membranes are usually untouched by the disease; recovery is prompt, and as a rule without complication or sequel. IV. Variola without Eruption This is always mild; it is usually found in well-protected subjects, or as the epidemic is fading. The symptoms of the stage of invasion sug- 338 SPECIFIC INFECTIOUS DISEASES gest as a rule a mild form of the disease; occasionally there may be consid- erable constitutional disturbance, fever, rachalgia and anorexia. The appearance of the patient continues good, there may be a prodromal rash —usually macular, non-scarlatinal—the disease ends favorably at the end of the period of invasion. Complications These modify the prognosis as a rule during pustulation. Complica- tions after the beginning of convalescence are infrequent. Among the debilitating incidents are added multiple phlegmons, deep abscesses of the muscles and suppurative adenitis. Erysipelas is always a serious complication, worse with the severer types of the disease: when facial and widespread with meningeal symp- toms it usually leads to death. Gangrene, local or widespread is serious. Deep sepsis and pyemia with confluence are among the serious com- plications. Bronchitis limited in extent is not unfavorable. Invasion of the smaller tubes by bronchial catarrh (bronchiolitis) adds a large element of danger in the possible development of bronchopneu- monia, which is not unusual. Croupous pneumonia is not frequent, occasionally when present, it is followed by lung abscess. Purulent thrombosis is always a serious complication. Pleurisy and empyema occasionally follow; as a rule the latter is the more serious, but if a late manifestation and relieved by drainage, most patients recover. Occasionally pulmonary tuberculosis has been a sequal of smallpox. Roily makes the statement that all lung and pleural complications give a bad prognosis. Invasion of the mucous membranes has been mentioned in the preced- ing pages, also edema of the glottis—a threatening complication. The complications due to eye, ear and nose invasion demand the con- sideration of workers in special fields. They are often destructive and permanent. Eye complications are present in from six to ten per cent of all cases. .Blindness due to suppurative disease of the eye, opacities of the cornea, and other deforming and damaging conditions depend on eruptive lesions, sepsis or pyemia. Brain complications have been mentioned as occurring during the acute stages of the disease and their prognostic significance discussed. There are cases in which acute encephalitis, aphasia consecutive to soften- ing of brain substance, have proved fatal. Leyden has reported cases complicated with diffuse myelitis, insular sclerosis and acute ascending paralysis (Quoted by Roily). In the epidemics of Central Rew York, INFECTIONS OF UNKNOWN OKIGIN 339 peripheral neuritis was exceedingly rare and psychic disturbances men- tioned by many observers have been absent. Suppurative arthritis is a serious and damaging complication: when these patients recover, anchyloses are the rule. The degenerative changes lead in serious cases to myocardial weakness, kidney invasion, while septic endocarditis is associated with a limited number of cases and invariably leads to death. Pericarditis, occasionally purulent, has proved fatal. Vaccination—Vaccinia But little space need be given to the prognosis of vaccination itself; when done'under strict antiseptic precautions, and these are continued, or if after a septic vaccination such strict cleanliness of the wound and person as the intelligent physician directs is practiced, there is practically no danger of infection if a pure animal lymph is used. The following conclusions are justified by large clinical experience and will prevent com- plications and annoyance if heeded, and the prognosis of vaccination will be uniformly good. Conclusions:—1. Arm to arm inoculation is justified. 2. Human scabs or crusts are never to be used. 3. Vaccination with animal lymph from reliable sources, preferably under State control, offers the best prognosis. 4. Attention to detail and strict asepsis are demanded; the subject and the operator need to be equally clean. 5. A sick child should not be vaccinated unless in the midst of an epidemic, or immediately after exposure to the disease. 6. Children or adults showing acute syphilitic lesions will react unfa- vorably and should first be subjected to_ antispecific treatment and later vaccinated, unless there is danger of immediate smallpox infection. 7. The same advice should be accepted in connection with congenital syphilitics. 8. Children or adults, reduced in health, with active tuberculosis, strikingly anemic, cachectic, with suppurating glands or those suffering from acute disease of the nervous system, including chorea, should first be prepared and later vaccinated. 9. Tetanus will not follow vaccination unless there has been contami- nation either through the lymph, from the body of the vaccinated subject or through dressings, or as the result of faulty technic (instruments, skin, etc.). 10. Auto-infection is avoidable, and is evidence of carelessness on the part of the vaccinated or those responsible for his care. 11. Disease, i. e., syphilis, acute infection, tuberculosis, “scrophula,” and smallpox itself, is never spread by clean vaccination. 340 SPECIFIC INFECTIOUS DISEASES 12. The vaccination of children lias no influence in preparing ready culture media in the body for the development of the other acute ex- anthemata (measles, scarlet fever, etc.). Considerations and Statistics.—How the prognosis of smallpox has been influenced by vaccination requires no detailed consideration: even the intelligent layman has this knowledge at his tongue’s end. A few telling statistics may be added to round this chapter. There was a time when smallpox was the direct cause of 1/7 of all deaths, and this, in the civilized countries of the earth—as fatal as was tuberculosis during the last quarter of the 19th century. During the 18th century 30,000 victims were annually claimed in France; in 1796, 25,646 died in Prussia when its population was 7,000,000. In Berlin 1/12 of all deaths were due to smallpox during the last decade of the 18th century. In countries today where vaccination is obligatory, note the change. Smallpox has been reduced, among the properly vaccinated to 0.25 to 0.35 per 100,000 population. The detailed statistics of Prussia show the disease to be present among 0.25 per 100,000 of population. In Eng- land and Wales during 1910 there were but 19 deaths due to smallpox. In the United States during 1909 and 1910 there were 54,451 cases of smallpox with 565 deaths—about 1 per cent mortality among the infected. Proper regulation of vaccination, making it obligatory in all countries, in all of our own states, well guarded quarantine after the early recogni- tion of the disease, revaccination at regular intervals (six to ten years) will surely lead to the disappearance of the disease. Finally we would call attention to the fact that protection conferred by vaccination is in direct proportion to the thoroughness of the operation and the number of cicatrices. Marson (London Smallpox Hospital) brought the results of his observations to the notice of the Royal Commis- sion of England through Sir Richard Thorne, from which I take the fol- lowing data: Cases of Smallpox Classified According to the Vaccination Marks Borne by Each Patient Respectively. Percentage of Deaths in Each Class Respectively Uncorrected.* Percentage of Deaths in Each Class Respectively Corrected.* 1836-51 1852-67 1836-51 1852-67 1.

Petit verole volante) Chicken pox is a highly contagious disease of childhood (adults are rarely attacked) of unknown origin; it is characterized by a vesicular skin eruption, which finally becomes pustular; is associated with mild con- stitutional symptoms, promptly yields and ends in full recovery, with developed immunity (99 per cent of cases) to the disease. The prognosis of varicella is almost uniformly good. In an experi- ence of thirty-five years I number hut one death due to the disease, that of a feeble child, four months of age, who died in convulsions with the characteristic rash fully developed. Deaths attributed to varicella, have, in all probability in the majority of cases been unrecognized smallpox, unless in correctly diagnosticated cases there have been serious complica- tions—which are exceedingly rare. Roily reports the autopsy of a child who died on the thirty-sixth day of the disease after a long period of dysentery following chicken pox, in which one of the pustules became gangrenous. There was also albu- minuria with hyaline casts. The autopsy showed dysenteric lesions in the large intestines, enlarged mesenteric glands, and cloudy degeneration of the cortical substance of the kidney. In this case dysentery was prob- ably an accidental accompaniment of varicella. Occasionally a death has been reported during chicken pox epidemics 342 SPECIFIC INFECTIOUS DISEASES due to hemorrhagic accompaniments. In most of these cases the children were either sick or reduced by previous illness. Complications Nephritis is a rare complication, usually ending in recovery. This is likely to he of hemorrhagic nature. Chorea has followed close upon convalescence, in children predisposed. Hemiplegia, encephalitis, pericarditis, pleurisy, suppurating adenitis, mediastinal abscess are also among the rare sequelae. Poly- or monarthritis, usually mild, have been present in a very small per cent of cases. Recovery without endocardial disturbance is the rule. Roily makes the following statement: “Chicken pox influences tuber- culous disease, as does measles, unfavorably. Tuberculosis is positively lighted into activity to such a degree that the patients usually die within a short time.” The combination of chicken pox with other acute exan- themata, scarlatina and measles, is an occasional coincidence. The prog- nosis depends entirely in these cases upon the severity of the infection other than varicella, which is not materially influenced by the presence of the latter disease. Roily. Mohr & Staehelin, Handbuch der Inneren Medizin, i., 142. Reference V. Measles (Morbilli, Rougeole, Rosolia) Measles is an acute exanthematous, directly contagious disease of early childhood (1st to 5th year) ; it is epidemic, characterized by fever, catarrhal inflammation of the air passages and photophobia, a disease in which positive immunity is not produced by one or more attacks, though as a rule the disease is not repeated. The bacterial cause of the disease is unknown. Its period of incubation is from seven to fourteen days. Patients continue to carry the contagion during at least sixteen days, the length of the period of safe quarantine. The blood and secretions, the desquamated skin, the clothing and bedding, hold the contagious element and transfer the disease to the healthy, in all probability, by direct contact. The disease is contagious during the period of invasion (3 to 4 days before the eruption) and after, during from ten to sixteen days. The severity of subsequent attacks is not influenced by previous infection. The prognosis of uncomplicated measles is almost uniformly good. The disease is either mild or malignant. Malignant measles is rare and is of hemorrhagic character, associated with deep discoloration of the eruption, marked invasion of the nervous system, degenerative changes in INFECTIONS OF UNKNOWN ORIGIN 343 the heart and kidneys, and causes death in most cases between the second and fifth day of the eruption. In some malignant cases the period of invasion is characterized by severe symptoms. There may be hemorrhages from mucous surfaces (epistaxis, etc.), a purpuric eruption, and children may die before the true measle rash appears. Fortunately, as already stated, these cases are exceedingly rare. The number of Koplih spots bears no relation to the severity of the disease. Temperature.—In the majority of favorable cases the temperature aver- ages between 102°-104° F., with corresponding acceleration of the heart action. The more severe cases are characterized by the deeper, “darker,” papular eruptions. The papules of mild measles disappear as a rule on deep pressure, the hemorrhagic papules do not disappear. Conjunctivitis.—The severity of the conjunctivitis in the majority of cases bears no relation to the severity of the disease. It not infrequently happens that measles with mild constitutional symptoms may have severe catarrhal conjunctivitis, as well as harassing bronchitis. Blood.—Leukopenia is the rule in measles; there is in favorable cases disappearance of lymphocytes (usually in the ascendency during early childhood) and relative increase of neutrophilic leukocytes. The white count in the average case is between 2,800 and 3,400. Leukocytosis dur- ing the period of eruption indicates the presence of a complication. Lym- phatic (cervical, mainly) enlargements are the rule are not of serious moment, and recede during the period of convalescence. Urine.—Febrile albuminuria is frequent and is found with marked con- stitutional involvement; it is not of serious importance save in the hemor- rhagic types of the disease. The mildest cases are those without catarrhal symptoms or few only, a modified rash, and but slight febrile movement. The severe types (non-malignant) of the disease in which the prog- nosis may be doubtful are those in which with a deep colored eruption there is hyperpyrexia, brain symptoms including the typhoid conditions, de- lirium, involuntary discharge of urine and frequent diarrheal stools, with rapid small dicrotic pulse. The periods of incubation and invasion may be associated with the symptoms of severe infection, which in occasional cases cease with the appearance of the eruption—the entire picture of the disease changing for the better suddenly, with fall of temperature and improved pulse. The reverse may also happen, i. e., mild periods of incu- bation and invasion with increase in the severity of the symptoms during the period of eruption. The Skin.—Cyanosis of the skin, a blue appearance of the papules, is found in the graver forms of the disease. The heart in these cases offers the best indications for prognosis; with evidences of cyanosis its muscu- lature is usually weakened by toxins, previous or associated disease. 344 SPECIFIC INFECTIOUS DISEASES Mortality.—The rule may be accepted that measles without complicar tions offers an exceptionally favorable prognosis. The average mortality of all cases of measles, with and without complications, is between four and 6 per cent, varying with different epidemics. The mortality is high- est during the first three years of life and lowest between the fourth and twentieth year. Measles after the forty-fifth to fiftieth year is less favor- able than during the more active years of life. Complications Bronchopneumonia is the gravest of all of the complications of measles; one-half to three-quarters of all deaths following measle infection are due to it. Bronchitis invading the smaller tubes is always a menace and when in these cases there is sudden increase of respiration with rising tem- perature and active playing of the accessory muscles of respiration, the development of secondary bronchopneumonia may be expected, and the prognosis is correspondingly serious. In some of these cases atelectasis may follow bronchiolitis—always a serious complication—or it may accom- pany or follow bronchopneumonia. Bronchopneumonia is a complication of measles in epidemics of average severity and duration in from five to eight per cent of all cases. The mortality of bronchopneumonia varies in different epidemics and ranges between 40 to 70 per cent. Measle infection invites the development of pulmonary tuberculosis and lights latent tuberculous diseases into activity. Besides this, the glandular system is so changed by the infection that it offers a suitable habitat for the tubercle bacillus from which long periods after infection, tuberculosis may spread. This is particularly true of the bronchial nodes in measles as well as whooping cough and other non-tuberculous infections of the upper respiratory organs. In some cases the tuberculosis resulting runs an acute and rapid course. Laryngitis may at times he severe, considerable edema may be present, and at times, ulceration; recovery is the rule. Croup with modern treat- ment offers a favorable prognosis. Whooping cough accompanying measles always increases the dangers of complications; bronchopneumonia is always to be feared and likely to be fatal with this combination. Ulcerative stomatitis or the usual less severe forms add painful symp- toms, but without further complication recovery follows slowly. Cancrum oris (Noma) is always serious, it may lead to large loss of tissue and has in my experience proved fatal in three-fourths of all cases. Otitis media suppurativa is present in about 7 per cent of all cases of measles, usually during convalescence. But few cases receiving prompt INFECTIONS OF UNKNOWN ORIGIN 345 attention lead to serious complications, such as mastoiditis, sinus throm- bosis or consecutive meningitis. Non-tuberculous adenitis, enlarged lymphatic glands following measles —usually in the cervical region—are likely to be associated with adenoids, and under surgical treatment and improved hygienic surroundings yield promptly. Persistent enlargement of cervical glands after measles even without fever or evidences of cheesy degeneration should be considered to be of tuberculous origin. Prognosis and treatment should he accordingly framed. Diarrhea and other symptoms of gastroenteritis early or late, may weaken the child but offer a favorable prognosis in the absence of other complications. Jaundice has never complicated my cases. It has been reported by others (Friedjung), with favorable outcome. Heart complications are rare. The malignant cases promptly show vasomotor paralysis, the governing spinal centers are soon fatigued by the toxins, and there are also degenerative changes in the myocardium itself. Nephritis is rare; it is not as serious as with scarlet fever and only rarely does it lead to death. If present it runs a benign course and leads to recovery and full restoration of kidney tissue in from three weeks to two months. Permanent damage to the eye resulting from catarrhal conjunctivitis is unusual. Occasionally with Tceratitis slight opacities have remained. Brain complications are usually secondary when late. Early convul- sions in young children are not always of serious import. Early delirium and the typhoid condition are present in the severer infections and with complicating meningitis and bronchopneumonia. They may also follow or accompany otitis, mastoid invasion and nephritis. Tuberculous meningitis may promptly follow measles; in the majority of these cases latent deposits were stimulated to activity by the added infection. Rarely is measles followed by polyarthritis with or without mild endocarditis; the same is true of pleurisy. The prognosis of these complications is good. Roily contends that when scarlet fever complicates measles, the prog- nosis is usually good; when however measles is added to existing scarlet fever, the course of the measle infection is severe and long and the mortal- ity is higher. The association of measles and ivhooping cough has already been men- tioned in connection with bronchopneumonia as a serious complication. Diphtheria (positive presence of the diphtheria bacillus in the dis- eased tonsils, etc.) when coincident with measles, is likely to prove serious and justifies a guarded forecast; when measles follows after diphtheria has run its course, the prognosis is decidedly better—usually full recovery results. 346 SPECIFIC INFECTIOUS DISEASES References Friedjung.

German Measles {Rotheln, Epidemic Roseola, Rubeola, Roseole epidemiqu German measles is an acute contagious disease of uncertain origin, epidemic or endemic; in its typical development it includes a rash, inflammation of the cervical lymphatics, and moderate elevation of tem- perature. It is less contagious than measles, and is probably transmitted by fomites. Second attacks are frequent. Children between the ages of two and ten are usually attacked. The period of incubation is unusually long—fourteen to twenty days. The disease is so mild in its manifestations that the physician’s usual function is to satisfy the parent by his differential diagnosis and the assurance of prompt recovery of the patient in from four to eight days. Cases with severe symptoms are exceedingly rare. Occasionally an epidemic includes cases in which separate symptoms are severe, as general lymphatic enlargement and slight nervous mani- festations, with possible convulsions in the younger children, hut these too make satisfactory recoveries. Recrudescence and relapses are occasional experiences. Complications Complications are infrequent. In our experience we have rarely been called to attend a child for any sequel of German measles. Among the complications mentioned by others are, bronchitis, wdiich always yields to treatment promptly; bronchopneumonia, which, rarely present, is less dangerous than with other exanthemata, as measles; acute gastroenteritis of transitory duration; and mild, slight enlargement of the thyroid gland with tenderness; and in some cases persistence during several months of enlarged lymphatics. Koplik has reported abortive cases without marked enlargement of lymphatics, no eruption, slight febrile movement leading to prompt recovery. Reference Koplik. Arch. f. Kinder krankh... 1900. INFECTIONS OF UNKNOWN ORIGIN 347 VII. Yellow Fever {Black Vomit, Fr. Fievre jaune, Span. Fiehre amarilla, Span. Vomito negro or prieto, I tat, Febbre gialla, Ger. Gelbes Fieber, Lat. Typhus icteroides) Yellow fever is an acute pestilential infectious disease, epidemic, of uncertain origin, conveyed by the mosquito, Stegomyia fasciata (calopus), which in the past has raged in tropical and insular America between the 45° north and 35° south latitude. The disease is characterized by a fever continuing for two or three days, followed by a marked remission which may end either in convalescence or the patient may pass into a critical stage in which there is “black vomit,” jaundice, hemorrhages, albuminuria, possible suppression of urine, and a typhoid condition with mental and nervous symptoms. The disease is always dependent on a temperature not lower than 70° T., hence the epidemic ends with the first frost. The disease was brought to San Domingo and Porto Pico by Colum- bus in 1493 in all probability. It rages along river and ocean fronts and is not likely to make much headway in country districts. Crowded cities, especially the neglected parts near the water, suffer most during epi- demics. Filth, marsh, faidty sanitary conditions invite the mosquito and spread the disease. Any American writing on the prophylaxis and prognosis of yellow fever must be stimulated by the achievements of American medicine. What the unselfish and practically unrewarded sacrifices of Walter Peed, Carroll, Lazear, Agramonte in the Western Hemisphere, and Myers of the Liverpool Commission, which resulted in the control of the disease in tropical and insular America, with the practical application by Colonel Gorgas of the facts thus furnished have accomplished for mankind, can- not be fully estimated today. The “Augean stables”1 have been cleansed, cities have been made safe, commerce, formerly stagnant during epidemics and long after, has been extended without obstacle, and the Panama Canal, the greatest achievement of modern times, has been completed, connect- ing the Atlantic and Pacific oceans, at the same time transforming a zone formerly pestridden into an inviting and healthy country. There has been no serious epidemic in the United States since 1897 when the disease last raged in Hew Orleans with a much lower death rate than during former epidemics. In all probability the disease will be completely effaced and the writing of the chapter on its prognosis will consequently prove to be a work of supererogation. Special Considerations.—There are a few points bearing on the progno- sis which should be considered. The degree of the fever of the period of invasion is usually in direct proportion to the severity of the disease. 348 SPECIFIC INFECTIOUS DISEASES The more rapid the pulse the more serious is the infection. Early black vomitus or hemorrhage is always serious. The collapse following the fall of temperature may promptly end life, for in no other disease does the heart muscle degenerate so rapidly as in yellow fever. Fatty granules displace the normal muscle; the heart cavi- ties are filled with dark brownish black blood. With the end of the remission in the serious cases symptoms referable to various internal organs present. Deep jaundice with hemorrhagic tendencies, profuse black vomit and albuminuria with casts, or complete suppression of urine make the prognosis bad, and with these symptoms from 50 to 60 per cent of patients have died. Disappearance of albumin and casts, and return of urinary function are favorable indications. Cases without deep jaundice, hemorrhages and with hut slight albu- minuria, few casts, moderate vomiting after remission offer a favorable prognosis. Large bloody stools are often found with profuse black vomit and are an expression of hemorrhage, and are serious. Free perspiration during the first stage is always favorable. An algid state of the patient at any time, with collapse, with or with- out hemorrhages, is among the most dangerous conditions presented by the yellow fever patient. Hemorrhage is a cause of death in a proportion of cases. Ecchymotic spots with multiple symptoms are unfavorable. Hemoglobin is reduced. White blood corpuscles vary between 5,000 and 20,000. Polynuclears are increased; eosinophilia is rare. Ilemo- globinemia and hypoleukocytosis are to be expected in the average cases. Marked degenerative changes in the liver are present and accompany the serious cases, with deep jaundice, great collapse and associated neph- ritis. In spite of great weakness following the first stage of the disease, those patients are likely to recover who do not have a return of fever, whose skin does not become dusky, and who are without typhoid symptoms. Rapid pulse in the second stage of the disease with typhoid or brain symptoms, including stupor, sordes accumulating on the teeth, dark and dry foul tongue, increasing jaundice, occasional convulsions, and suppres- sion of urine are unfavorable. If the patient enters the third stage, and the temperature shows a decided rise and many of the untoward symptoms mentioned in the pre- ceding paragraph are present, death is likely to follow. The period from the fifth to the seventh days is most ominous. No case of yellow fever is safe until convalescence has been fully established. The negro is less susceptible to yellow fever than is the white man, and when infected bears the disease better. There is a difference of 30 INFECTIONS OF UNKNOWN ORIGIN 349 per cent in the mortality in some epidemics between the death rate of whites and blacks. The Chinese are more resistant than whites. The American Indian is but little less liable to the disease than is the European (Davidson). The larger number of victims are claimed between the twentieth and fortieth years of life. Yellow fever is more fatal to men than to women; children bear the disease better than do adults. Immunity follows a single attack of the disease: exceptions to this are rare. The mortality varies in different epidemics from 15 to 85 per cent and is highest among alcoholics; lower in precincts where hygienic conditions are good. Reference Davidson. Allbutt & Rolleston, System of Medicine, ii., part ii. VIII. Foot and Mouth Disease The disease rarely occurs in man. It is characterized by the forma- tion of vesicles, blebs and bullce in the mouth, nose, lips, on the tongue (often with salivation), and on the fingers and toes. The bacteriologic cause of the disease is unknown. The disease is contracted from cattle— goats, sheep and pigs. The udder and mammary glands of cattle are often diseased and from these sources the disease may be spread. The contagion may be conveyed through milk, butter, cheese, sputum, nasal secretions; particularly by the rich cream of the infected animals. Boiling the milk destroys the disease-producing power, simple heating does not. Direct contact with the infected does not cause the disease save in the rarest instances: the skin of workers in dairies is seldom infected. The most frequent cause is the drinking of raw milk, rich cream and milk products (cheese, etc.). The formation of vesicles is associated with more or less febrile move- ment in man. The buccal mucosa is the most frequent seat of the vesicular eruption after a period of incubation varying from two to ten days. Fever with malaise, and often other evidences of constitutional disturb- ances, are present from the beginning. Dryness and burning sensation in the mouth are among the disagreeable symptoms. The vesicles appear on the third to sixth days of the disease with a fall of temperature and salivation. The symptoms in the adult need cause no alarm in spite of an added diarrhea in some cases. In very young children, nurslings par- ticularly, who are infected, depleting diarrhea may occasionally cause death and the prognosis is less favorable than in the adult. Symptoms are likely to persist during two weeks in mild cases, as long as four to eight weeks in the severer infections, with considerable loss of flesh and strength. The healing process is complete, the ulcers left by the vesicles 350 SPECIFIC INFECTIOUS DISEASES are promptly covered with epithelium and the neighboring inflammation subsides. The lesions about the fingers and toes are characteristic. Vesicles or bullse form, leading to limited superficial losses of tissue, often pus de- posits about the nails (paronychia)—all of which heal in from two to eight weeks. The average duration of the disease is fourteen days. In occasional large epidemics the mortality has reached eight per cent. When there are doubts concerning the diagnosis, consequently prog- nosis as well, these may be overcome by the inoculation of sheep or goat with the serum or pus of the vesicle. Prophylactic measures will ultimately lead to the extermination of the disease, for it is easy to recognize the presence of the epizootic in a dairy and to institute prompt quarantine against the infected cattle and the milk. IX. Ephemeral Fever (Febricula, Symptomatic Fever) Ephemeral fever is a febril condition of short duration and of un- known origin, which in all probability is symptomatic and hardly deserves to he dignified as a disease per se. It has always seemed to me that whenever the clinician has been forced to diagnosticate “Ephemeral fever” he admits ignorance of the cause of the febrile disturbance. Symptomatic fever would in all proba- bility better characterize the complex; than “ephemeral fever.” Ephemeral fever may be an expression of one of several infections, and is in some cases an abortive form of typhoid, paratyphoid, scarlet fever, measles, rheumatism (arthritis) or even pneumonia. This con- clusion is justified because the disease is found at times of epidemics of the above mentioned diseases. Sporadic cases are frequent. In children the complex is often coincident with digestive disturb- ances due to dietetic errors. It has, in children susceptible to febrile movement on slight cause, repeated itself at short intervals during a number of years, usually ending, never to return after the seventh to tenth year of life. The duration is rarely longer than three days: usually from twenty-four to thirty-six hours. I know of no fatal cases of the disease. X. Infectious Jaundice—Weil’s Disease (1886) (Epidemic Catarrhal Jaundice, Morbus Weilii) Weil’s Disease is an epidemic acute infection, characterized by gastric symptoms, fever, jaundice, constitutional symptoms, albuminuria, and INFECTIONS OF UNKNOWN ORIGIN 351 severe muscular pains. There is in severe cases delirium, nephritis, hematemesis, melena and epistaxis.- The pulse is rapid in proportion to the severity of the infection. In the average cases the temperature may be continuously high dur- ing from six to seven days. In some of these there may be delirium which is not of serious import. As a rule, the evidences of constitutional infection begin to improve with the end of the first or the beginning of the second week. Prostration may appear alarming during several days but if the pulse remains of fair character, the disease being self limited, patients bear the symptoms through the critical period and recover. The disease appears among consumers of meat mainly, and has been found in butchers very largely. As patients recover, the spleen and liver recede and with the disap- pearance of jaundice and albuminuria, normal functions are restored. The disease shows a low mortality, though in some endemics it has reached 10 per cent. Relapse after the end of seven to ten days complicates one-half of all cases; in some, the fever then continues during three to four weeks; most of these recover. Convalescence is slow. In fatal cases there is an in- crease of kidney symptoms, and deep invasion of the nervous system; purpuric spots cover the body and there are hemorrhages from the mucous membranes. Marked heart weakness with myocarditis may end the scene. In some cases pneumonic infection may prove a serious complication. XI. Sweating Sickness (Febris miliaris) Sweating sickness is characterized by fever, excessive sweating, and an eruption of miliary vesicles. It has never been epidemic in the United States so far as I can determine by a search of medical literature. The disease proved fatal at the end of the fifteenth century in a large number of cases during the first epidemic of which there is a record in England, and has been known since in Germany and on the continent as the “Eng- lish sweat.” Hirsch in his monumental work reports 194 epidemics between 1718-1879. Epidemics begin and end suddenly, and never con- tinue long. Large numbers are stricken during epidemics; the active and healthy adult and women are most subject to the disease. The duration of the disease averages seven days. The disease during the initial English epidemic had a high mortality, 80 to 90 per cent; in recent epidemics, on the Continent, the death rate has been 20 per cent. Death took place on the third or fourth day usually. SPECIFIC INFECTIOUS DISEASES 352 The prognosis is worse early in the epidemic than after it has spent its force and is ending. In some cases death has been sudden during the first or second day of infection. Hirsch. Handbuch der Histor.-Geograph. Pathologie. 2. ed., 1881. Reference XII. Herpetic Fever (Febris herpetica) Herpetic fever is a symptom complex of unknown origin, character- ized by fever—usually mild—with some constitutional disturbances, in rare cases severe, slight enlargement of the spleen. All of these symptoms continue during two to five days when the herpetiform vesicular eruption appears, usually covering a considerable portion of the body, though at times only a cheek and adjacent skin or an ear or the neck; occasionally the eruption may become hemorrhagic. In rare cases in which there is an hemorrhagic tendency, nephritis hemorrhagica develops. The prognosis is good; recovery is the rule; the duration is short. Relapse often occurs and is of short duration, lasting about one day. XIII. The Fourth Disease {Dukes’ Disease, Filaton-Dukes’ Disease, Rubeola scarlatinosa, Scarlatinoid) This is an acute symptom complex which the Americans and Germans have not yet entirely accepted as a disease per se, fully described by Dukes, bearing close resemblance to abortive scarlet fever and also rotheln, with less desquamation than follows the former but greater than in the latter. The constitutional disturbances are of short duration; the period of transmission of infection is also short, while the period of incubation is unusually long (9 to 20, or even 30 days). The prognosis is uniformly good and there are no complications or sequelae. XIV. Epidemic Parotitis {Mumps) Mumps is an acute epidemic disease, characterized by swelling and non-snppurative inflammation of both parotid glands, contagions, of un- certain origin, associated with moderate constitutional disturbance, a long period of incubation (eighteen days) leading to full recovery in from seven to ten days. Immunity follows a single attack with rare exceptions. INFECTIONS OF UNKNOWN ORIGIN 353 Complications.—In about 25 to 30 per cent of male adults, rarely in young boys, the infection is associated with orchitis, usually single, and attacks the right testicle oftener than the left. The complication runs its course in from seven to fourteen days causing some atrophy of the testicle in from 30 to 40 per cent of cases. In rare cases the changed testicle in after years has been found tuberculous. There is but insig- nificant enlargement of the spleen. In exceptional cases, a chronic swell- ing of the parotid gland follows which persists during many years. Among the serious complications reported in medical literature which have resulted in death, are meningitis, encephalitis, gangrene of the paro- tid, nephritis and laryngitis {croup). Less serious complications have included otitis media and externa, Meniere's disease, and insignificant ocular disturbances, such as conjunctivitis, keratitis and iritis—rarely paralysis of the ocular nerves. Nephritis is rare; slight albuminuria with few hyaline casts is present in occasional cases. Symptoms referable to the nervous system if serious are an expression usually of added infection. There may, in rare cases, be a transitory typhoid condition from which the patients promptly lift themselves: this is an early complex. Serious heart lesions, endo- and pericarditis I have not met in my epidemics though others have reported these at long intervals. Poly- arthritis when present is of short duration, benign and without endo- carditis. Severe joint and muscle pains (myalgia) are frequent. I have never met a case of oophoritis due to epidemic parotitis. Many hold that there is a reciprocal relation which invites change in the ovaries when the paro- tid is diseased, and vice versa. Mortality.—The low mortality of epidemic mumps is shown by the statistics of Ringberg who found seven deaths in 58,331 cases of the disease. Reference Ringberg. Quoted by Krause. Mohr & Staehelin, Handbuch der inneren Medizin. 1911. i, 239. XV. Glandular Fever—Pfeiffer’s Disease (Driisenfieber) Pfeiffer’s disease or glandular fever is an acute febrile disease of childhood—it also occasionally attacks adults—of uncertain origin, char- acterized by headache, dysphagia, congested tonsils and pharynx, by enlargement of the cervical lymphatics (usually bilateral) with tender- ness ; in some cases many distant glands are involved (axillary, inguinal, mesenteric, et cetera). The febrile period ends in from three to seven days; the glandular enlargement and pharyngeal redness may appear any time between the second and fifth day. 354 SPECIFIC IHFECTIOUS DISEASES In a recent epidemic in Dry den, Hew York, there were as a rule, bilateral enlargements of the cervical lymphatics which appeared with- out redness of the skin. The children were without marked consti- tutional disturbances after the fourth day; the glandular enlargements gradually melted away in from seven to twenty-one days. In the counties between Central and Eastern Hew York sporadic cases have occasionally followed very limited endemics. As a rule in these districts the disease has not attacked many children. The duration of the disease is short. The fever ends before the seventh or eighth day. Recovery has been complete in all cases seen, and without complication. Ho case of which I have knowledge has ended in suppuration, though such cases have been reported by others; neither has nephritis, otitis nor retropharyngeal abscess followed. Suppuration has seemed to be more frequent in the adult than in children. The associated edema of the soft palate and palatine folds may prove exceedingly painful and extension to the glottis serious. In the anemic, and children otherwise reduced in health, convalescence has been somewhat protracted. XVI. Hydrophobia {Rabies, Lyssa, Wuthrankheit) Hydrophobia is a disease the bacterial origin of which is unknown, transmitted to man by the bite of rabid animals through the infected saliva, especially that of the dog. The deeper the bite the greater the laceration and the more saliva introduced, the more likely is hydrophobia to follow. The majority bitten by rabid dogs never develop rabies. The figures given by Romberg, showing 15 to 20 per cent of those bitten to he infected, correspond very closely with those of American and other continental observers. Hydrophobia follows bites of the exposed parts of the body—hands and face oftener than bites where clothing has served to protect and hold the saliva of the rabid animal. The development of the disease depends in all probability upon the injury and infection of the peripheral nerves which serve to transmit the infection to the central nervous system, i. e., the cord and the medulla. An important prognostic fact is the possibility of the transmission of the disease from the infected animal to man several days before the onset of symptoms in the former. The period of incubation is unusually long, varying from one to nine weeks—occasionally several months. INFECTIONS OF UNKNOWN ORIGIN 355 Those bitten by rabid dogs who have not received the Pasteur treat- ment, in spite of a negative condition are not to be considered immune until the end of at least three months. The healing of the wound inflicted by a rabid animal, in one unpro- tected by inoculation (Pasteur), does not in, any way argue against or in favor of ultimate infection. Burning, itching, throbbing and pain, when not due to autosuggestion, are soon followed by swelling, depression, melancholia, malaise, great uneasiness and restlessness, anorexia—all positive evidences of the pro- dromal stage of the disease. These symptoms may continue from three to eight days. The typical uneasiness referred to the throat and mouth begins before the end of the first stage. The second stage, or period of excitation, is associated with spasms, pain in the throat—the latter promptly provoked by the attempt to swal- low liquids—alarming dyspnea, cyanosis and irregular breathing, due to spasm of the respiratory muscles. The frequency of the spasms increases as the disease advances and the true “phobia” is fully established; the sight of fluid, the noise of running water, the touching or moving of the patient, any jar, noise or the passing of a light are each sufficient to provoke spasms. The intervals between the spasms grow shorter, and the patient cannot be nourished; there may be slight febrile movement, 100-103° F., occasionally higher (104-105° F.), the pulse grows small and rapid and after from one to three days of spasms varying in different cases and during which death may occur, the majority of patients fall into the third stage or stage of paralysis, in which the weakness is overpowering. There may be paralyses (usually of the extremity bitten) at times hemiplegia, or in occasional "cases ascending paralysis. Coma and death results from respiratory paralysis in most cases; in some syn- cope suddenly ends life. The duration of the third stage is from three to twenty-four hours. Death may occasionally follow the prodromal period without the symp- toms of the second stage of the disease. The third stage (paralysis) promptly follows and is of short duration. Conclusions.—From the foregoing abstract of symptoms and the course of the disease as presented in its three stages, it is clear that the prognosis is absolutely bad in all cases of fully developed hydrophobia. Occasional5 cases have been reported cured, in which it may be assumed that the diag- nosis rested on a doubtful foundation. I feel justified in repeating that the hope of the subject actually infected lies in the prompt cleansing of the wound and the early prophylactic treatment mentioned (the latter is now readily obtainable} ; that the greater the laceration of tissues and the deeper the bite, the greater is the danger of rabies developing. The Pasteur treatment requires three weeks, during which, at inter- 356 SPECIFIC INFECTIOUS DISEASES vals, the patient is inoculated with the virus of rabies (dogs) which has been modified by the repeated inoculation of rabbits. The antirabic material is an emulsion of the spinal cord of the inoculated rabbits and to be effective the prophylactic treatment must have been completed at least two weeks before the end of the period of incubation. Statistics.—Statistics prove further that of those bitten by rabid ani- mals only 0.5 to 1 per cent who have been treated prophylactically, develop rabies, against 15 to 20 per cent among the untreated. Reference Romberg. Die Acuten Infedionskrankheiten von Mehring u. Krehl. 8. ed. XVII. Dengue (Breakbone, Dandy Fever) Dengue is a rare disease except in tropical and subtropical climates. It is acute and of unknown origin, characterized by sudden onset, severe pains in joints and muscles, fever with cutaneous erythema, and charac- teristic stiffness of gait (“dandy gait”). It is usually panepidemic or epidemic, attacking a large proportion of the population suddenly. It is rarely found above the 41° north latitude, and Manson has expressed the opinion that the disease follows slowly along the lines of sea travel. The disease is likely to attack entire families, all under a single roof, and spreads from house to house along the same street. While the specific germ is unknown, Ashburn and Craig proved that the disease is conveyed by the mosquito (Culex fatigans). (Investiga- tions regarding the Etiology of Dengue Fever, 1907.) There have been no epidemics in the Northern United States. The last large epidemic in America was in 1897 when 20,000 of Galveston’s inhabitants were stricken, with practically no deaths. In a limited epi- demic in Charleston in 1828, three deaths were reported. From the above data it is clear that the prognosis is good and that complications are exceedingly rare. Convalescence may be slow, asso- ciated with prostration and weakness, with a persistence of erythema, and at times marked inertia and mental torpor. These symptoms yield fully, though considerable time is often required for full restoration to health. The average length of the attack is from seven to eight days. Immunity is of short duration, averaging about twelve to fourteen months. Reinfection during the same epidemic has been noted by several clinicians. Section II Diseases of the Respiratory Apparatus A. Diseases of the Nose 1. Acute Catarrhal Rhinitis (Coryza) Acute catarrhal inflammation of the nasal passages is either a primary infection characterized bv all of the usual changes in the mucosa of catar- rhal disease, in which the secretion is materially increased, and finally purulent, or secondary to other infections, oftener in children with measles, whooping cough, bronchitis, laryngitis, syphilis, scarlet fever, diphtheria, or it may follow the use of the iodin compounds in both chil- dren and adults (often with idiosyncrasies). Children suffering from hereditary syphilis are particularly subject to continuous snuffles, as are also those of lymphatic temperament, who on the slightest exposure are liable to contract “cold.” Both adults and children are subject to “colds” which are transitory as a rule, and without complications lead to recovery in a few days. Most secondary (infectious) rhinitides are associated with more or less pharyngitis; the constitutional symptoms and gravity depend entirely on the nature of the primary disease. In all uncomplicated rhinitis the disease is self-limited, and does not materially interfere with the patient’s activities. With grippal infection, scarlet fever, diphtheria and nasal involvement, extension to the surrounding sinuses is possible. With in- vasion of the middle ear, there may be mastoid suppuration or final pyogenic disease of the brain (meningitis, encephalitis, invasion of the veins, etc.). In children, neglect, particularly during periods of influ- enza, may lead to extension into the air passages, and final broncho- pneumonia. Much depends upon the resistance which the subject offers to the 357 358 DISEASES OF THE RESPIRATORY APPARATUS infection as well as its malignancy. With diphtheria, nasal and glandular involvement is always serious (See Diphtheria). Syphilitic coryza in children—non-malignant—usually yields to treat- ment. If the deep structures are involved, recovery is naturally slow (See Syphilis). Polypoid growths in adults often continue catarrhal discharges which are relieved by radical treatment. There are adults who develop nasal catarrh on slight cause, in whom there is also asthmatic breathing. Unless there are local disturbances, these symptoms are dependent upon neural or constitutional causes—and the prognosis should be given accordingly. Catarrhal conditions of the nasal mucosa are often continued by pharyngeal adenoids. In these cases, usually children, the removal of the succulent growths brings relief. These patients are always worse during wet seasons. Children with lymphatic enlargements (cervical) and nasal catarrh dependent upon local lesions demand prompt attention, and are cured by modern radical treatment. The recurrence of coryza in the hypersensitive adult and child is favorably influenced by treatment which increases resistance. 2. Hay Fever (Bose Cold, Autumnal Catarrh) Most cases of hay fever are found in subjects who are predisposed to catarrhal disturbances, when have an abnormal and sensitive naso-respira- tory mucosa. The leading clinical features of hay fever which follow the action of the pollen of certain plants, grasses, or the inhalation of irritating dust, are catarrhal and spasmodic. The catarrhal symptoms include coryza, free discharge, conjunctivitis; the spasmodic, repeated sneezing and asthmatic attacks. Naturally the pollen of a certain plant being the cause of the symp- toms in the individual case, the onset of the symptoms corresponds with its appearance in the air, and the release must be materially influenced by its disappearance and the immunity which it produces. The latter is short lived and questionable. The prognosis of hay fever for life is good—it is self-limited and subject to recurrence. Complications are exceedingly rare. Occasionally, for some reason, without change of climate during subsequent seasons of pollen irritation, the complex does not return. There are probably no cases of rose cold which are not favorably influenced by climatic change. I have never met a death directly traceable to autumnal catarrh, nor a single extension to the air cells to cause bronchopneumonia. The asth- matic breathing and paroxysms disappear with the nasal symptoms. Emrys-Roberts has demonstrated an interesting blood picture in con- DISEASES OF THE NOSE 359 nection with hay fever and asthma, which includes increased eosinophilia coincident with the asthma. He believes that there is an alteration in the blood picture, which besides the eosinophilia includes a decrease of hemoglobin, marked polycythemia, and increase in large mononuclear lymphocytes, the presence of vacuolated and degenerated leukocytes and a degree of leukopenia. “An altered, but modified blood picture persists during the intervals between the seasonal attacks.’’ Occasional cases have been benefited by the surgical treatment of local anomalies; considering the number treated, the results so far as the relief of nasal and respiratory symptoms during the periods of exacer- bation, have not been encouraging. The influence of vaccination against hay fever is at present sub judice; its influence on the control of the disease cannot be decided without fur- ther investigation. Lowdermilk claims good results from the use of toxin extracted from pollen with the addition of an autogenous vaccine, in all cases complicated by the presence of a bacterial infection (Freeman, I.). Dunbar’s investigations justify the use of his pollantin; if his con- clusions are correct, relief and a moderate added immunity ought to follow. In the majority of cases it will be found that at present we have no remedy which positively aborts the symptoms. Cocaine, used by physicians or patient,’ can only lead to temporary relief and encourages the formation of an enslaving drug habit. 3. Epistaxis {Nosebleed) Nosebleed which is not due to mechanical insult (traumatism) is dependent upon lesions of the nasal mucosa (ulceration, catarrhal inflam- mation, dilated or diseased veins) or it is secondary to constitutional defects, including the hemorrhagic diathesis, purpura, scorbutus, hemo- philia, the grave anemias, leukemias, carcinomatosis, malignant and non- malignant infections, sepsis, malignant endocarditis, typhoid fever, yellow fever, measles, smallpox, scarlet fever, pertussis, icterus and various poisonings. Nosebleed is often an early evidence of arteriosclerosis, it may recur repeatedly with this condition; particularly does this happen with associated interstitial nephritis and hypertension. It may prove a salu- tary warning; slight bleeding with uncomplicated arteriosclerosis is insignificant. Nosebleed is a frequent symptom of heart lesions and cirrhosis, or other liver lesions. Epistaxis is not to be considered pathologic if moderate, when sudden changes to a high altitude cause it. Occasionally nosebleed may be an 360 DISEASES OF THE RESPIRATORY APPARATUS expression of vicarious menstruation and is of no importance. The sig- nificance of nosebleed which is secondary to the conditions above men- tioned has been fully considered in connection with the separate infec- tions; with malignancy it is always grave, also with the constitutional diseases and grave anemias. ISTosebleed per se does not often threaten life. In the exceedingly weak, with hemophilia, grave anemias, severe and uncontrolled bleeding does occasionally hasten death. Children during the period of growth, very often have recurring nosebleed which ceases at puberty; it is with- out significance. With the diseases of the ductless glands I have occa- sionally found insignificant nosebleed; one of my cases of acromegaly had frequent recurrences without ulcerative changes in the mucosa. B. Diseases of the Larynx 1. Acute Laryngitis Acute catarrhal laryngitis may be either primary or secondary. Primary laryngitis is rarely associated with significant constitutional symptoms; occasionally there may be slight elevation of temperature, but this is evanescent, and barring the discomfort due to the changed larynx, hoarseness and cough, there are no evidences of illness. Such laryngitis runs its course in a few days to a favorable termination. Most cases show some associated inflammation of the trachea. When the larynx is inflamed from strain, the symptoms disappear after a short period of laryngeal rest. The severity of laryngitis which is secondary depends entirely on the primary cause. With corrosive poisoning, edema may promptly follow or the swelling may be sufficient to cause asphyxia. Life is threatened; prompt surgical or local relief is demanded in such cases. The acute laryngitis of croupous diphtheritic origin is separately con- sidered (See Diphtheria). With measles, in occasional cases, laryngo-tracheitis causes alarming symptoms which may be complicated by bronchopneumonia. Without the latter complication most of these children recover (See Measles and Bronchopneumonia). Acute laryngitis with edema following fracture of the larynx or other wounds may prove dangerous. Foreign todies caught in the larynx may cause laryngitis and swelling. These conditions are within the domain of the surgeon, who with modern devices succeeds in relieving most of them. Primary or secondary catarrhal laryngitis in children often causes DISEASES OF THE LARYNX 361 symptoms of croup and is known as “catarrhal croup” or “Pseudocroup.” It is as a rule found in children who are subject to catarrhal laryngitis, and who whenever they “catch cold” are “croupy.” In some there is slight elevation of temperature. This condition, when uncomplicated, is relieved in a few days after a period of cough, hoarseness and nocturnal increase of symptoms. Sudden increase in the frequency of the respira- tions with rising temperature and pulse, create the suspicion of compli- cating bronchopneumonia. The laryngeal picture of laryngitis, when uncomplicated, will prove reassuring and is an aid in foretelling the course of the disease—also in diagnosticating the subglottic form, which mjay prove serious. The im- provement of tbe general condition of the patient, the relief of associated lesions of the nasopharynx or other inflammatory conditions in the upper air passages, the relief of a rheumatic diathesis when present, favorable housing, climatic conditions (environment)—all prove powerful factors in not only relieving these patients in the acute attacks, but in preventing their return and final chronic laryngeal change. 2. Chronic Laryngitis Chronic laryngitis is either primary or secondary. The cases which follow repeated acute attacks (primary) can only be cured by long periods of rest, often climatic changes. Chronic primary laryngitis due to the continuous inhalation of dust, tobacco or other irritating substances, if unrelieved leads to organic changes in the vocal cords, which continue annoying. ISTone of these cases are relieved if repeatedly subjected to the factor which causes them. Laryng- ologists are agreed that but few laryngitides of the chronic type are pri- mary, “except from the improper use of the voice” (Ballinger). Secondary laryngitis may he due to nasal, nasopharyngeal or tonsillar disease. Removal of the primary lesion acts favorably on the laryngeal changes. Chronic gastritis due to alcohol is frequently associated with chronic laryngitis, as are also cirrhosis of the liver, chronic gastro duodenitis, heart lesions causing venous enlargement, mediastinal growths of Hodg- kins and leukemic origin and long residence in an unfavorable climate. The prognosis in all of these cases necessarily depends upon the depth of the change (hypertrophy, atrophy, polypoid or other productive lesions) and the ability to remove the underlying cause in the individual case. The voice in chronic alcoholics who have had long-continued symptoms often remains hoarse in spite of the discontinuance of stimulants. Pulmonary tuberculosis and chronic bronchitis, chronic interstitial pneumonia (the pneumoniokonioses) may be complicated by non-tuber- culous chronic laryngitis—persistent and often unyielding to treatment. 362 DISEASES OF THE RESPIRATORY APPARATUS 3. Edema of the Larynx {Edematous Laryngitis, Edema of the Glottis) Primary laryngitis may cause marked edema of the larynx. As a rule edema of the larynx is secondary to vascular obstruction, dependent upon the pressure of growths—malignant or non-malignant (cervical- mediastinal, etc.); heart, kidney, lung lesions, constitutional diseases—- diabetes, syphilis, the grave anemias (pernicious and leukemic), also purpura. Syphilitic tuberculous ulcerations may cause edema of the larynx. The general dropsies of nephritis at times include sudden edema of the glottis. Peritonsillar suppuration (quinsy) may suddenly cause edema of the glottis, as may other infections which cause cellulitis or perichondritis, including erysipelas, Ludwig’s angina, and malignant growths of the neck. With measles, typhoid fever, scarlet fever, diphtheria or other infec- tions, the glottis may become edematous; life is always threatened when such edema exists—it causes acute and alarming symptoms, whether de- pendent upon grave underlying causes or conditions which uncomplicated do not threaten life. This is particularly true of angioneurotic edema (Quincke’s disease) separately considered. We have seen one case of diabetes in which there was one-sided swelling of the larynx, demanding immediate operation. Edema due to injury, foreign bodies and surgical affections is men- tioned in connection with the laryngitides. The laryngoscope leads to the recognition of the extent of the danger and often suggests treatment which prevents fatal asphyxia. The imme- diate prognosis for life must always depend upon the ability to overcome the obstruction and prevent recurrence. Our art (laryngology) is so far advanced that whatever the primary cause, but few will lose their lives from the edema itself who are treated early and rationally. The organic diseases of the vital organs which serve as the most fre- quent cause of edema of the glottis usually terminate fatally. 4, Laryngismus stridulus {Spasmodic Laryngitis) The “holding of the breath” by the child is the characteristic feature of laryngismus stridulus. Spasm of the glottis may be caused by a variety of laryngeal and nervous disturbances. It is an affection of the nervous system of infant life (6 months to 3 or 4 years) and is often provoked by emotional causes. Children often while crying “hold their breath” without any serious result. I consider spasm in connection DISEASES OF THE BRONCHI 363 with tetany and infantile convulsions, to which section the reader is referred. The majority of my cases have been found in children with neurotic tendencies, rachitic, underfed, and emotional. Some of these show the characteristic reactions of tetany. The spasm involves the diaphragm as well as the adductors of the larynx and for the fraction of a minute the appearance (cyanosis) alarms the parent. The inspiratory stridor which follows is always welcome to the over-anxious observer. Probably the deaths which have been attributed to laryngismus stridulus are charge- able to the status thymolymphaticus. I have never in our practice seen a death from laryngismus stridulus. Adult stridulus is occasionally met in practice; it may be hysterical or evidence of another neurosis. It is not serious. The laryngeal crisis of tabes dorsalis includes characteristic stridor and may recur at short intervals without serious result. Mueller (Fr.) claims that in rare cases laryngeal crises may cause sudden death by asphyxia. 3. Tuberculous Laryngitis See Tuberculosis, Section I, B. 6.

Acute Bronchitis Acute bronchitis is one of the most frequent of all diseases, at the same time one of the most benign. It is easily the most frequent of all diseases of the respiratory tract. The majority of acute cases are pri- mary, more frequent during the fall and winter months always mate- 364 DISEASES OF THE RESPIRATORY APPARATUS rially influenced by sudden climatic changes and exposure. In otherwise healthy subjects, without added complications, it offers an absolutely favorable prognosis. Many acute bronchitides begin as laryngeal or pharyngeal catarrh and descend after a day or two of local symptoms. Bronchial Catarrh.—Bronchial catarrh is associated with more or less tracheitis. The bronchi are symmetrically inflamed (both sides) and the medium-sized bronchi are mainly involved. The bronchitis of early life and old age when neglected or extensive is likely to extend to the smaller bronchi; hence it is always serious and there is great danger of secondary bronchopneumonia. The bronchiolitis of early and late life is often sec- ondary and is a complication of influenza, measles, whooping-cough, diph- theria and other infections. When in the young or old, bronchopneumonia develops with bron- chiolitis, or disseminated bronchitis extends to the capillaries and air cells, an enormous element of danger is added. (See Bronchopneumonia.) The prognosis of bronchopneumonia following the bronchitis of measles and whooping-cough is always grave (see Measles and Whooping-cough), particularly in very young and feeble children. Atelectasis—collapse of air cells—is one of the serious complications of bronchiolitis and bronchopneumonia. With bronchiolitis or fully de- veloped islands of bronchopneumonia, and extensive collapse of air cells (atelectasis) the condition of the patient is always serious—marked cyanosis and cardiac insufficiency may end the scene. Whenever with acute bronchitis there is persistent high temperature and respiration is correspondingly accelerated, the possibility of compli- cating pneumonia should be considered. In uncomplicated bronchitis the acute symptoms begin to yield on the third or fourth day; the expectoration becomes more profuse and purulent; the acute symptoms (malaise, slight fever, anorexia and cough) show marked improvement, and uninterrupted return to health is the rule. Dyspnea and rapid respiration in all cases when present demand im- mediate interpretation; they are not symptoms of uncomplicated bronchitis. Cough may not cease entirely before the end of the second week. If it persists beyond that time and there is some evening temperature, with or without acceleration of the pulse, the suspicion of a tuberculous infec- tion in the absence of other infection or cause should be strongly enter- tained, and the case treated (watched) accordingly. Heart weakness in the aged and infants with disseminated bronchitis is always of serious import. Primary uncomplicated bronchitis in otherwise healthy individuals always leads to recovery. The virulence of primary infections with which bronchitis may be associated must always be considered to be of para- mount importance. DISEASES OF THE BRONCHI 365 Acute bronchitis, complicating chronic heart lesions, nephritis or other visceral diseases may seriously influence the prognosis. The prog- nosis in these cases depends largely on the general condition of the patient, the resistance and the extent of the bronchial infection. The same is true of bronchitis as it arises suddenly with cerebrospinal meningitis, polyarthritis, cqronary disease, pulmonary emphysema, mitral lesions, rachitis, sepsis, typhus and smallpox. 2. Chronic Bronchitis Chronic bronchitis may follow acute catarrhal bronchitis. As a rule, chronic bronchitis depends upon long-continued hyperemia of the bron- chial mucosa which is secondary to pulmonary obstructions and dependent upon valvular lesions, weakness or disease of the right ventricle, pulmonary emphysema, the pneumonokonioses; particularly the inhalation of dust laden air. With chronic bronchitis there is but little tendency toward return of the membrane to a normal state. While the atrophic or hyper- trophic changes are not overcome, life may not be threatened, for some of the patients live to reach old age and many die of intercurrent disease. Bronchiectasia and bronchial stenosis may result from long continued bronchitis. Chronic bronchitis is a frequent cause and accompaniment of pulmonary emphysema. With this complication the right heart is over- taxed, and finally dilates and hypertrophies. There are forms of chronic bronchitis which are materially affected by seasonal and climatic influences. Thus with “winter cough” the patient may cough or have symptoms only during cold weather, and is promptly relieved by climatic treatment. Most chronic bronchitis is favor- ably influenced by warm weather or by a dry equable climate. There are cases in which chronic change in the mucosa causes an exces- sive mucopurulent secretion with cough and final secondary heart and trophic changes—clubbed fingers (See Chronic Pulmonary Arthropathy). These cases are exceedingly chronic; they are types of bronchorrhea. In these as in most chronic types of bronchitis there is more or less peribron- chial proliferative change. The dry bronchial catarrh of Laennec is at once exceedingly troublesome and chronic, because of the persistent dry cough, with only the occasional expectoration of a small pearl-shaped plug and the secondary heart changes, emphysema with dyspnea, which are practically uncontrollable. Chronic bronchitis dependent upon chronic heart lesions is often mate- rially relieved during long periods by the improved condition of the myo- cardium. But few of these cases cease coughing entirely during the peri- ods of improvement, but they remain comparatively comfortable. In a large number, the cough with excessive expectoration (bronchorrhea) con- 366 DISEASES OF THE RESPIRATORY APPARATUS tinues without materially interfering with the general condition of the patient. The primary disease always determines the outcome. Any form of bronchitis may be associated with asthma, and in most, emphysema is more or less developed. While as above stated chronic changes in the bronchi do not tend to mend, the outcome so far as life is concerned is not discouraging, save as it is influenced by the primary circulatory or other faults which cause the disease, or by the secondary lung or heart changes which the bronchitis itself produces. Chronic bronchitis with “fixed thorax” may he materially improved in well selected cases by plastic operations on the thorax (See References). Chronic purulent bronchitis with asthma (purulent bronchorrhea,) and emphysema may be associated with polypi, adenoids, or nasal perfora- tions; while the majority are not cured by radical surgical treatment of the nasopharyngeal anomalies, many are materially relieved. Climatic and seasonal changes influence these cases favorably. Chronic putrid or fetid bronchitis is secondary to gangrene of the lung, empyema, tuberculosis, syphilitic or malignant disease. These cases are not curable; the length of life is measured by the primary cause and its extent. Distant secondary changes (metastases) may promptly end life (brain abscess, infarct, amyloid disease, etc.). 3. Bronchiectasis Dilatation of the bronchi may he either (1) congenital or (2) ac- quired. (1) The congenital type (Grawitz) (bronchiectasis universalis) is ex- ceedingly rare. Most congenital cases have been found to he unilateral. There is no treatment which influences these defects; the amount of dis- turbance and influence on the life of the child depends upon the extent of the bronchiectasis. In those who live, secondary pulmonary and heart changes must he expected. (2) The acquired brochiectasis is always secondary. Reference is made to bronchial dilatations in connection with infectious pulmonary dis- eases and chronic bronchitis (See separate sections). Classification.—Barty King classifies the acquired bronchiectasis as follows: 1. Chronic bronchitis. 2. Bronchopneumonia. 3. Chronic pneumonia. 4. Pneumonic. 5. Pleuritic. A. Pure B. Tuberculous. C. Traumatic Bronchiectasis 1. Aneurism. 2. Tumor. 3. Foreign body. 4. Syphilis. DISEASES OF THE BRONCHI 367 All bronchiectases are either (a) diffuse or cylindrical, or (b) circum- script or saccular. (a) The diffuse or cylindrical forms are not as a rule extensive. (b) The circumscript or saccular forms are either single or multiple. In severe cases a section of the lung shows the appearance of innumer- able saccular dilatations resembling multiple cavities. Symptoms and Course of Complication.—The symptoms and course of the complications depend on the size and number of the bronchiectatic cavities, the character of their contents and the amount of constitutional disturbance caused by absorption and the nature and extent of the primary lesion. Causes and Development of Bronchiectasis.—The most frequent cause of bronchiectasis is chronic inflammation of the bronchial wall which is associated with or is a sequel of measles, whooping-cough and influenza— usually during early life. A large number of bronchiectatic cavities which develop during early life increase in size with advancing years. In these cases the walls are thickened by growth of connective tissue. With chronic bronchitis there may be no advance in the size of the cavities or there may be diffuse dilatation of many bronchi which increases (Aschoff). With pressure from tumors or stenosis due to the presence of a foreign body, syphilitic cicatricial tissue following ulceration, tuberculous ulcerations or aneurismal growths, the cavity, one or many, may increase and the symp- toms are correspondingly aggravated. Associated Symptoms.—Atelectasis and bronchiectasis may be associ- ated conditions. If the former is extensive and arises suddenly, the dan- gers are at once apparent because of cyanosis, respiratory and circulatory embarrassment. In children and in the aged with bronchopneumonia, acute bronchiectasis with or without atelectasis is always serious and usu- ally leads to death. The symptoms which are associated with good sized dilatations are characteristic. Cough may be absent during the larger part of the day, troublesome early in the morning when it is accompanied by the emptying of the pocket which brings relief. The size of the cavity may be approximately decided by the quantity of secretion (expectoration) which it holds. The complications depend, as already hinted, upon the primary causes and the changes consecutive to the dilatations—local and constitutional. The average chronic case without excessive and multiple dilatations lives on, never without some symptoms, but in fair health; not a good subject for added infection—pneumonia particularly. With extensive and multiple dilatations and excessive purulent secretion, with fetid expectora- tion the prognosis is always grave. Patients, with febrile movement after many years of invalidism become septic, develop anemia (secondary), are exhausted and emaciated, and often die with advanced amyloid degen- eration in many organs. We have seen cases, particularly syphilitic, re- 368 DISEASES OF THE RESPIRATORY APPARATUS main stationary and in good general health after intensive treatment dur- ing many years. 4. Bronchial Asthma Bronchial asthma is a neurosis, usually of reflex origin; characterized hy paroxysmal dsypnea, narrowing of the bronchi by spasm, hyperemia or exudation; commencing suddenly, as a rule; soon accompanied with loud wheezing breathing, spasmodic cough, prolonged and defective expiration, in which the respiratory muscles are all overtaxed, the lung is distended, expectoration is usually profuse, there is associated bronchitis and emphy- sema, and in chronic cases changes in the heart, thorax and blood—all of these symptoms are without attending fever. Charcot-Leyden crystals (small colorless octahedra) are found in the sputum in most cases and are not of prognostic significance, neither are the Curschmann spirals. Curschmann considered the presence of the spirals as positive proof of inflammation of the finer bronchi (bronchio- litis exfoliativa). The presence of blood in the sputum is not necessarily or usually ominous; in the severer attacks the sputum is at times bloody. Large hemoptysis is not a symptom of primary asthma. Eosinophilic cells, usually present in the sputum, are of no prognostic significance. The individual attack may end in less than one hour; as a rule it continues several hours (2 to 4). Severe attacks may continue during several days with only slight and not complete remission. Meltzer in 1910 called attention to the resemblances of asthma to anaphylactic shock and offered the suggestion that “it is an anaphylactic phenomenon.” Certainly there are a number of facts which strengthen the theory of Meltzer, particularly those which prove the frequency of recurrence under similar conditions and exposure to the same causes which prove hypersensitivness, abnormal reaction, or as Meltzer says “asthmatics are individuals who are sensitized to a specific substance.” The disease is not fatal per se. There are facts which prove the enor- mous influence of a psychic element in inviting and continuing symptoms, particularly in neurotic individuals in whom no organic lesion can be found. In some cases suggestion has been powerful in determining the onset of attacks. West mentions the presence of premonitory symptoms which if heeded may abort or prevent the paroxysm—“like the aura in epilepsy.” Trousseau a sufferer from bronchial asthma had his attacks with great regularity “as the clock struck three in the morning.” . One attack usually leads to more; it is unusual to find one attack the only paroxysm during the entire life of the patient. The more frequent the attacks, the lighter they are, as a rule, though there are exceptions to this. Postponing of attacks or increasing the length of the intervals is DISEASES OF THE BRONCHI 369 favorable and in some cases such behavior is followed by almost complete immunity. Heredity.—Heredity is a factor of some importance in connection with prognosis. It is noted in about 2 of 5 cases. Salter’s statistics in 217 cases showed 84 with a strong heredity, and often direct from parent to child and through several generations. Salter and West report the occurrence of asthma among several children of a family without the disease in the parent. The prognosis for complete relief is better in the cases without inherited taint. Sex.—Salter’s statistics show 153 cases of which 102 were males, and 51 females. Age.—Asthma in young children often disappears after one or more attacks. Salter offers the following table to show the age at the time of the first attack in 225 asthmatics: During 1st year 1-10 years 11 cases 1 \ 81 • per cent. 10-20 years 30 cases 12.8 per cent. 20-30 years 39 cases 17. per cent. 30-40 years 44 cases 19. per cent. 40-50 years 24 cases 9. per cent. 50—60 years. 5 per per cent. 60-70 years 1.4 cent. 70-80 years 1 case 0.4 per cent. Salter says that the chances of cure are good when asthma develops before the age of 10 years; if before 20 it may be cured; if between 20 and 40, it will probably not be cured; if after 60 it will certainly not be cured. Occupation.—Occupation is not of as much importance in etiology or prognosis as is generally supposed. Those most exposed are not likely to develop asthma unless they are predisposed and work in an atmosphere of dust. It has seemed that those who use their voices most are subject to asthma (preachers, lawyers, school teachers, etc.) hut this remains with- out confirmation. Once present, occupations which continue irritating, pro- voke seizures and prevent long periods of immunity. Additional Influences and Symptoms.—Gouty and diabetic families show a surprisingly large number of asthmatics, and in these the prognosis for complete freedom is not encouraging. In young children the associa- tion of intractable eczema and asthma is striking and frequent. A num- ber of our cases with this combination proved subject to pneumococcus in- fection. In one child we had, as a complication, four threatening broncho- pneumonias during four consecutive winters. This boy has grown to man- hood cured of both asthma and eczema. Another active chap with the same clinical picture, was less fortunate; he died in his third broncho- pneumonia. Asthma is comparatively frequent with urticaria. Bulkley’s figures 370 DISEASES OF THE RESPIRATORY APPARATUS are high (7 per cent). Asthmatics both young and old, are as a rule, unusu- ally active and alert and when at work are strenuous. Location and climatic conditions are of great importance in most cases but there are absolutely no indications which the individual case offers which can lead the clinician to determine the location or climate which will most favorably influence the majority of “idiopathic asthmas.” Most asthmatics, it may he safely concluded, are favorably influenced by change to a higher altitude, particularly if they are living in the lowlands. Pa- tients are able to get some relief from 'postural change, particularly by raising the shoulders and the scapulae. Clavicles and spine are fixed, the patient leans forward, the hack is curved, the head rests on the hands, the anteroposterior diameter of the chest is increased while the diaphragm is depressed and the respiratory effort is extreme as it raises the ribs. The respirations are long, noisy, wheezing, though not abnormally rapid. Profuse expectoration gives considerable relief, while in the more trou- blesome attacks the sputum is scanty and the asthma “dry.” Blood Pictuke.—The leading characteristic of asthmatic blood is eosinopliilia. The eosinophils are often increased to from 10 to 40 per cent of the leukocytes. Higher counts are recorded. Early in the attack the eosinophils are usually reduced hut soon there is a decided increase; with the decrease of eosinophils early, there is a lowering of the lympho- cytes and the polymorphonuclear cells increase. Later in the attack there is evident eosinophilia, as suggested above with marked lympho- cytosis, all of which fall as the attack is relieved. Asthmatics often show persistent lymphocytosis. But little of value for prognosis is gained from blood examination though in the terminal stages of some secondary asthmas (heart and pulmonary lesions) polycythemia may he present. General Considerations.—I have elsewhere mentioned the paroxysmal breathing, cyanosis, and asphyxia which lead to sudden death (thymic death) now known as the status thymo-lymphaticus. This is not to be confounded with bronchial asthma. Cardiac asthma is usually a terminal symptom of heart or cardiovas- cular disease in which myocardial degeneration is the prominent feature and in which pulmonary edema is likely to lead to death. Renal asthma is not unusual with nephritis in which the heart muscle is advanced in degeneration and uremia may he chronic or acute. The heart is erratic, feeble and arhythmic, and with increasing evidences of cardiac and respiratory insufficiency—pulmonary edema—death follows. There are cases dependent upon gastric or gastro-intestinal or hepatic disease, either organic or functional. Many asthmatic paroxysms may he traced to faulty digestion or organic disease of the digestive apparatus in which diet and radical treatment exert a marked and favorable influence on the asthmatic attacks. When asthma is symptomatic of grave organic dis- ease (cardiac, renal, pulmonary or gastric) the prognosis is had; this, DISEASES OF TIIE BRONCHI 371 however, is not veritable asthma. Spasmodic or bronchial asthma which is a neurosis as originally defined in this chapter, is the only variety which should be included in the consideration of true asthma. With vagotonia of Eppinger and Hess (see Diseases of the Sympa- thetic System) the subjects develop asthma with the other symptoms in- cluded in the complex (increased susceptibility to pilocarpine, nervous dyspepsia, hyperacidity and erratic heart) and are materially relieved by adrenalin. As in hay fever, so in vagotonic asthma the eosinophilia is characteristic. There are occasional asthmas which seem reflex from some genito- urinary disturbance. Menstrual anomalies, pregnancy and uterine dis- placements in the female, and sexual disturbances and neurasthenia in the male have occasionally been considered among the causes. Most of these patients are neurotics and are influenced by suggestion rather than by radical treatment in most cases. There is practically no danger to life during the attack. There are so few cases recorded in which death occurred during an attack that it may be safely assumed that in these there was some complication. Fagge, Franzee and Bamberger each report one case of death during the asthmatic attack. Asthma does not per se shorten life. It has been noted that asthmatics often live to old age. I saw the case of a salt boiler who had asthma over 60 years and died at about 90 years of age. In chronic asthmatics with marked secondary changes including emphysema and heart lesions (dilated right ventricle) life may be shortened by such com- plications. In young subjects and in the aged there is danger from bron- chopneumonic infection. The association of asthma and tuberculosis is strikingly rare, though in some cases the x-ray shows calcified and tuberculous glands in asthmatic subjects (Fr. Mueller). When attacks increase in frequency and severity at the same time and their length increases, the chances of cure are re- mote. The chances of relief are increased by decreasing severity of the attacks and lengthened intervals. The positive discovery of the cause of the reflex materially improves the chance of amelioration or cure. I have often been disappointed by radical nasal treatment in cases which seemed to depend upon nasal growths or other anomalies, though occa- sionally success either complete or partial has followed. West says: “Although it is clear from what has been stated that there is more in the relation of nasal irritation to asthma than has been until recent years believed, and although most marked relief is given in some cases, still so far as we know at present it is impossible to recognize be- forehand with certainty the cases in which relief will be given and those in which it will fail.” The conclusions of West are sound and safe to follow in offering a forecast in those cases in which some nasal abnormal- ity seems to be the irritant. 372 DISEASES OF TILE RESPIRATORY APPARATUS Asthma sometimes disappears after intercurrent disease or it may alternate with other and graver diseases of the nervous system. Salter, Lloyd, and Taylor report cases in which asthma alternated with epilepsy; Trousseau reports the cure of asthma after gout but persistent hemicrania followed. Eulenberg records a parallel case in which asthma alternated with hemicrania and angina pectoris. Savage and Conolly Xorman prove the relation between asthma and insanity; the two affections alternate at times. There was freedom from asthma so long as the insanity contin- ued; on cure asthma returned. Long-continued asthma, while it does not, as already suggested, shorten life without some added complication, in the advanced stage may lead to the “fixed thorax” with emphysema and all the associated physical signs. In these cases dyspnea may finally he continuous and with heart changes, dilatation of the right heart, edema of the lung may develop and threaten life. I have seen two cases, in extreme condition, relieved hv plastic operation on the thorax. The improvement of both was prompt and seems to continue. But few chronic asthmatics are without evidences of incurable chronic bronchitis between their paroxysms. Secondary asthma depending on pressure of growths upon the pneumo- gastric offer no hope of relief. Among the most distressing cases of asthma are those due to metastases or primary growths (mediastinal). In many of these the dyspnea and cough are paroxysmal, the breathing noisy and characteristic of true asthma. In the terminal stages with these conditions the breathing is continuously bad with marked cyanosis. To prevent serious accident or death ‘the anaphylactic action of diph- theria and other antitoxins administered to asthmatics demands serious attention in the presence of the diseases for which these are used.

Fibrinous Bronchitis (Croupous Bronchitis) Eibrinous bronchitis may be either acute or chronic. When acute it is usually secondary and molds—fibrinous casts of the bronchi—are formed because of descending croupous inflammation with diphtheria, occasionally with croupous pneumonia or any pseudomembranous disease of the upper respiratory organs. With all of these conditions extension into the finer bronchi and air cells with the formation of casts adds enor- mously to the danger of the primary disease. Caustic poisons may in rare cases cause fibrinous bronchitis. In occasional malignant neoplasms of the lung casts of the bronchi have been formed. Primary fibrinous bronchitis is exceedingly rare. In an active prac- tice of over thirty ears I have seen but one case. This was chronic; it commenced in a girl at the age of eight years. Casts of the bronchi formed without materially affecting her growth or general condition, vary- ing at intervals during six years, after which she made a full recovery and has never, after thirty odd years, had recurrence. Ho treatment influ- enced this case; it ran its course and the habit of making casts was lost. This patient never had asthma during the active years of the disease. 6. Whoopinjj-Coujjh See Infectious Diseases (Section I). D. Diseases of the Lungs (The Pneumonias and Pulmonary Tuberculosis are considered in Sec- tion I—Infectious Diseases.) 1. Circulatory Disturbances of the Lunjjs Congestion (a) Active (b) Passive (c) Edema of the lungs. (a) Active Congestion of the Lungs (Woillez disease).—It is questionable whether active congestion of the lung ever exists as an inde- 374 DISEASES OF THE KESPIRATORY APPARATUS pendent disease. Most of these cases have been strongly suggestive of abortive pneumonia. Woillez in 1854 called attention to congestion pul- monair e idiopathique, which develops after chilling of the surface (usu- ally from a fall into cold water or injury of the thorax) and in which there is sudden chill, some fever, pleuritic pain, cough, dyspnea and expectora- tion which settles in two layers one frothy and yellowish, the other muci- laginous ; usually there are pneumococci present. In occasional cases the expectoration is absent. The symptoms run a favorable course in four or five days. There is leukocytosis. The disease in rare instances runs a more protracted course but ends in recovery. Active hyperemia not depending on pneumonia, with sunstroke, inha- lation of poisonous gases or acute miliary tuberculosis is of no clinical importance (Staehelin), and of such rare occurrence that its occurrence is questioned. (b) Passive Congestion.—Passive congestion of the lung may fol- low mechanical obstruction secondary to tumor, insufficient heart force or decompensation. The condition is always secondary and serious because of the gravity of the initial disease. In the terminal stages of malig- nancy, constitutional diseases, the wasting and acute diseases of the aged, with valvular lesions, most frequently initial disease, chronic and acute nephritis, and purpura, passive congestion may develop, and in some con- tinue long enough to produce brown induration (Aschoff). I have, with all primary disease to which passive pulmonary hyper- emia may be secondary, dilated on its prognostic significance. Unless the circulation can be sufficiently stimulated or the pressure removed when present, the prognosis is absolutely bad. The suddenly arising engorgement of the pulmonary vessels witli heart disease is usually associated with edema (See heart lesions, also pulmonary edema). Hypostatic congestion of the lung is always secon- dary; it is a frequent attendant of all long continued infections and in these cases causes engorgement of the dependent portions of both lungs, as a rule. It is almost constantly present with pneumonia, severe typhoid infection, the infections of old age and early life; when in the latter they are serious when the patient has been kept on the back during long periods. Hypostatic congestion may prove a serious complication with fractures of the hip and other bones, particularly in delicate old and non-resistant patients. With marked dyspnea, cyanosis and weak heart, also with edema, the prognosis is grave. Hypostatic congestion with the majority of infections does not lead to death or materially influence the chances of recovery unless it is exten- sive, and the heart is enfeebled by overpowering toxemia. Postural change and other prophylactic treatment do much to prevent the development and advance, when present, of the complication. With cerebral apoplexy, opium poisoning, brain tumor and other brain DISEASES OF THE LUNGS 375 lesions, uremia and a variety of other unfavorable 'primary diseases hypo- static congestion may prove to be the leading cause of death. (c) Pulmonary Edema.—Edema of the lung is never to be lightly regarded whatever the primary condition which causes it. References to the clinical and prognostic significance of pulmonary edema are fre- quently made in all separate sections dealing with conditions which may cause it. There is no more alarming condition, none which demands prompter relief that life may he prolonged than that which presents when the patient is literally drowning in his own serum. I say “life pro- longed” for in the larger number of cases pulmonary edema is secondary to grave conditions. On the other hand, there are occasional edemas from which patients make full recoveries; these are with such underlying con- ditions as can be relieved, or they do not recur. I have found among my favorable cases the edema secondary to acute nephritis, to sudden cardiac insufficiency with acute infections, pneumonia, typhoid, measles, myocardial weakness with endocarditis and polyarthritis, specific aortitis, coronary sclerosis and myocardial degeneration; in all of these active treatment proved sufficient to bridge the patient over the critical period. The unfavorable hypostatic congestions are those in which the heart is so far degenerated or the toxemia so malignant that response to general and local stimulation is impossible. I have called attention (see Pneu- mococcemia) to those rapidly fatal cases of pneumonia in which the air cells are promptly filled with blood serum which in a few hours drowns the patient. With nephritis, heart insufficiency, arteriosclerosis, the prog- nosis in the presence of an acute pulmonary edema is bad. With angina pectoris and acute edema the chances of recovery are small. In many of these cases overeating is an important exciting factor of the attack. With any heart lesion which leads to insufficiency—decomposition— the addition of edema is life threatening. With emphysema and heart {right) dilatation, suddenly arising edema leads to cyanosis and often to death. These patients are usually among the more chronic and debilitated. Sudden edema with obesity and fatty heart, is, as a rule, fatal. Angio- neurotic edema may cause edema of the lung; it is rarely fatal—in fact it is not frequent. I have seen epilepsy with edema recover. Any cause which weakens the left heart sufficiently to interfere with the pul- monary circuit and cause edema, as already strongly hinted, unless promptly relieved will lead to death. The duration of the single edema of the lung in severe cases cannot be long, for when severe, it is associated with such reduced myocardial strength that death is likely to follow soon. Pulmonary edema by rigorous treat- ment with fatal primary conditions may be overcome. It is likely to recur, and may finally claim its victim. 376 DISEASES OF THE RESPIRATORY APPARATUS Aschoff.

Pulmonary Hemorrhage (a) Hemoptysis (b) Pulmonary Infarct (a) Hemoptysis Coughing or raising of blood from the air passages is symptomatic of many primary conditions; the most frequent cause of blood spitting is tuberculous disease of the lung (See Tuberculosis). Hemorrhage from the pulmonary vessels may be due to traumatism when the nature of the injury and extent will make prognosis easy. Ac- tive hyperemia causing hemoptysis is inflammatory in most cases. The causes are acute pneumonia, tuberculosis, and Staehelin mentions ma- laria. With pneumonia we have never seen hemoptysis sufficiently pro- fuse to deplete the patient or cause weakness. The pure bloody sputum of pneumonia is not encouraging—such complication is found in the graver cases. (There are occasional exceptions.) The hemorrhages—hemoptysis of malignant growths, rarely cause serious weakness. In the terminal stage occasionally large vessels may be eroded, and weakness already extreme becomes threatening. Vicarious menstruation may include hemoptysis which, aside from the psychic effect of the bleeding, is without depressing or weakening effect. Ulcerative disease of the upper air passages, pharynx, larynx and tra- chea may cause slight hemoptysis. Hemoptysis due to mitral stenosis often relieves the patient’s breathing; it rarely causes more than transitory weakness. In all such cases the possibility of tuberculosis should be con- sidered. Wilson has grouped his cases of hemoptysis in heart disease in three principal groups: “(1)Those in which with an antecedent or concomitant lesion of the heart, the hemoptysis is essentially of pulmonary origin, as in tuberculosis, croupous and sometimes bronchopneumonia, infarct, acute and chronic bronchitis, emphysema, bronchiectasis and malignant growths.” “(2) Those in which vascular structures are the seat of hemorrhage, as aneurism, erosion caused by foreign bodies or malignant growths, and primary and secondary diseases of the blood.” “(3) Those which are primarily and essentially of cardiac origin.” DISEASES OE THE LUNGS 377 In the first two groups the prognosis is grave as the primary disease undermines resistance and the hemoptysis is profuse. In this chapter we consider the hemoptysis from many of the sources mentioned without asso- ciated heart disease, the latter naturally under certain conditions adds to the danger. With a good myocardium, and in the majority of cases be- cause of the limited loss of blood, the prognosis is good so far as the hemoptysis is concerned, except in aneurism. All clinicians have noted that moderate hemoptysis in mitral stenosis is usually followed by material relief of dyspnea and other cardiac symptoms. Mackenzie says that with mitral stenosis “at various stages the patients may be seized with great bleeding from the lungs. There doubtless the cause is the back pressure in the pulmonary circulation and rupture of the blood vessels. As a rule, this is a grave sign, the patient dying sometimes shortly after the attack.” We have not often met these large hemorrhages with mitral stenosis. In most hemoptyses due to heart lesions the immediate prognosis is good; naturally the course of the disease is molded by the nature of the primary heart defect. The bleeding of pulmonary gangrene is not as a rule profuse; in one case we saw a fatal hemorrhage—this is exceptional. The slow bleeding of the aortic aneurism is ominous, while the rupture of the sac into the air passages is always promptly fatal. Aneurismal bleed- ing from whatever vessel into the bronchi, whether slow, sudden or profuse, leads to death. With chronic bronchitis blood streaked sputum is frequent. Hemop- tysis is rarely profuse. The admixture of blood is usually due to violent coughing. Ho significance need be given to this bleeding. With whooping-cough and measles in children and adults during vio- lent paroxysms, hemoptysis often occurs without influencing the general condition. With syphilitic ulceration of the upper air passages, hemorrhage is not often severe. There is usually only a slight addition of blood (See Syphilis). With malignant purpura, hemoptysis may be either slight or it may be profuse. When it is present it is only one of several complicating condi- tions with profound constitutional changes and should be accordingly in- terpreted (See Purpura; also Scurvy). Some cases which often look serious finally recover. Hemophiliacs occasionally bleed freely from the bronchial mucosa, particularly when there are catarrhal or other inflammatory changes. The general and circulatory condition of the patient, the blood state, the nature of the primary disease, and the quantity of blood lost make progno- sis possible and usually correct. Hemoptysis with arteriosclerosis and chronic interstitial nephritis in gouty subjects particularly, will usually prove more alarming than serious; 378 DISEASES OF THE RESPIRATORY APPARATUS the underlying primary disturbances make prognosis possible. The loss of blood is not usually great. Abscess of the lung rarely causes large hemorrhage; with a persisting cavity there may he repeated small hemorrhages. In these cases the blood and pus are mixed. These slight bleedings do not influence the course of the primary disease materially. Profuse hemorrhage from any cause into the air cells may, particu- larly in patients weakened and reduced by chronic disease, lead to suffo- cation or heart weakness. The presence of blood in the lung may by aspiration to distant parts of either lung—if it holds pathogenic germs (the pneumococcus particu- larly)—lead to acute inflammatory processes, just as, after pulmonary hemorrhage in tuberculosis, the bacillus and other microorganisms may he aspirated to dependent parts of the lung, and acute pneumonic tuber- culosis may result. (b) Pulmonary Infarct (Pulmonary apoplexy) Wedge-shaped (usually) or other infarcts into the lung tissue are dependent upon chronic heart lesions, malignant or septic infections with embolism or thrombosis of the pulmonary artery, mechanical obstruction from pulmonary or circulatory anomalies which produce the characteris- tic 'heart lung.” If the blood effused is not great, there may he hut slight hemoptysis and few subjective or objective symptoms. In such cases the clot is finally expectorated as a black or dark purple airless lump (West, S.). If there is extensive infarct (malignant endocarditis and other septic conditions, chronic nephritis) an entire lobe of a lung is suddenly filled. It is impossible always to tell from the hemoptysis how extensive the infarct may be. I have seen large infarcts with but little blood spitting. In these cases the physical signs, dyspnea, and heart condi- tions decide the immediate prognosis. Infarct of a large branch of the pulmonary artery or sudden obstruc- tion with myocardial insufficiency (left ventricle) in which with hemop- tysis the subjective symptoms are severe, promptly leads to death. Pulmonary infarct may, after varying periods of hemoptysis, lead to pulmonary gangrene with change in the expectoration; these patients die with symptoms of sepsis. The conditions which lead to the majority of pulmonary infarcts are serious and are separately considered with the infections, heart and other lesions. There are many chronic heart and other lesions in which pulmonary infarcts do not lead to death; they may recur. We have, with chronic cases of malignant endocarditis had re- peated hemoptysis due to infarcts from which the patients have rallied, to die of brain infarcts or other complications. Multiple infarcts are not infrequently found in many organs of the body, post mortem. DISEASES OF THE LUNGS 379 Mackenzie {James). Diseases of the heart. Oxford, 1910; also 1808, 226. Samson (4. E.).

Chronic Non-tuberculous Pneumonia Included in this consideration of Chronic Non-tuberculous Pneumonia are: (a) Chronic pneumonia. (b) Chronic interstitial pneumonia. (c) The pneumonokonioses. (a) Chronic Pneumonia There are occasional cases in which the exudate present in the air cells in the third stage of pneumonia remains unchanged and continues an irritant, producing changes which lead to chronic pneumonia. These are the so-called cases of delayed resolution or unresolved pneumonias. As already suggested (croupous pneumonia) the majority of “unresolved pneumonias” prove ultimately to be tuberculous; they are cases of em- pyema, or the persisting symptoms are due to some other added complica- tion. It is however possible for delayed resolution or “unresolved pneumonia,” either fibrinous or catarrhal, to lead to chronic, non-tubercu- lous changes in the lung. The tendency is toward the proliferation of connective tissue and carnification. There is, with both types of pneu- monia which become chronic, more or less peribronchitis with the changes mentioned. It is impossible to differentiate these cases from chronic inter- stitial pneumonia; indeed, the pathology of both is identical when the disease is fully developed. Further references to the prognosis of chronic pneumonia are therefore included in this chapter. Chronic pneumonia is usually the outcome of the atypical types of the acute disease; it often follows measles and whooping-cough in children who are burdened by diatheses (tuberculous or rachitis), and in all cases there is great danger of the ultimate tuberculization of the lung. (6) Chronic Interstitial Pneumonia (1ST on-Tuberculous ) {Chronic Pneumonia, Cirrhosis of the Lung, Fibroid Phthisis) Chronic interstitial pneumonia is a productive inflammation of the lung, characterized by the formation of fibrous tissue ivhich is the product 380 DISEASES OF THE RESPIRATORY APPARATUS of granulation tissue, causing induration and contraction of the organ. The process may be peribronchial or interalveolar. A large number of these cases follow chronic pleurisy and empyema (pleurogenous pneumonia). The disease is therefore associated with dense adhesions which lead to retracted and misshapen thoraces with re- sulting respiratory embarrassment and further secondary changes, to which I will again refer. Mediastinal growth, aneurism, abscess of the lung, peribronchitis, syphilis of the lung, hydatid disease and traumatism are among the causes of pulmonary fibrosis to be considered in making the prognosis. (c) The Pneumonokonioses ( Zenker) Pneumonokoniosis is an occupation disease in which there is fibrosis of the lung. The disease may be caused by the inhalation of dust, flour, or other noxious substances. The inhalation of coal dust (antliracosis), steel dust (Zenker’s sidero- sis), stone particles (silicosis)-, mineral dust (chalicosis) and cotton (byssinosis) are among the leading causes of fibroid proliferation in the lung. In most of these cases the greater changes are in the apices of the lung where macroscopically there are abundant evidences of fibroid growth, misshaped and contracted lung, and collapse of large portions of the lung, while other changes are included which must be appreciated to justify safe prognosis. General Conclusions The prognosis of (a) chronic pneumonia following the acute lobar in- fection is often good. This is true of those cases in which the process is limited—the fibrosis does not extend—where there are no secondary heart changes, and after a reasonable time the lung learns to adapt itself to the slight abnormality which remains unchanged. This forecast is applic- able to chronic lobular pneumonia of limited extent. When the process is extensive, patients are made uncomfortable be- cause of cough, respiratory insufficiency, consecutive heart changes, and resulting deformities. They may live during many years and die of in- tercurrent disease, but they are never well and their activities are limited unless perchance they are favorably influenced by climatic conditions. Bronchiectasia, atelectasis, tuberculization, right heart insufficiency and stasis within the pulmonary, portal, and renal systems (ultimate dropsies) are among the complications which influence prognosis. The further consideration of the prognosis of (b) chronic (non-tuber- DISEx\SUS OF THE LUAGS 381 culous) interstitial pneumonia, and (c) the pneumonokonioses, justifies the following conclusions: Unless the process is due to specific deposit (rare) there are no means at our command which influence existing fibroid changes. Cases of pleurogenous origin may live during many years in compara- tive comfort without advance of the process; if the heart has accommo- dated itself to the changed conditions there are no threatening symptoms. These patients are easily fatigued and are often short of breath. In all chronic cases the heart offers valuable prognostic data. The right heart is naturally overtaxed by the obstruction in the pulmonary circuit and with extensive fibrosis, dilates; this leads to hypertrophy with accentuation of the second pulmonic sound. With advancing disease the dangers of myocardial insufficiency and degeneration are added. In the terminal stage, the patient’s life is threatened by the resulting obstruction in the venous system, causing in turn cyanosis, liver and kid- ney changes, splenic hyperemia, ascites and edema. The extent of the bronchiectasis and atelectasis in these cases is a powerful and unfavorable factor with failing heart strength. The involvement of the bronchial glands (lymph nodes) is of great sig- nificance and often lays the foundation for extension of tuberculosis. A surprisingly large number of chronic interstitial pneumonias includ- ing the pneumonokonioses develop tuberculosis. We found in the knife grinders who worked over emery wheels, before the modern protective appliances were installed, that all developed chronic interstitial pneumonia; that over 90 per cent of these who lived over ten years, showed positive evidences of pulmonary tuberculosis. We have found the workers in an American knife factory who came from Sollingen, Germany, where they had previously worked and who had continued at their work more than five years, that, in spite of modern appliances, all of them showed evidences of siderosis; many of these have died of tubercu- losis. The chronic interstitial changes of the workers in coal mines and in an atmosphere of coal dust, as has been proved by experiences in America and oil the continent, rarely become tuberculous. “All forms of chronic interstitial pneumonia may develop and die of tuberculosis” (Jiiergem sen). Juergensen makes the following statement: “I hesitate to diagnose interstitial pneumonia and to exclude tuberculosis so long as there is normal physical strength and great mental activity, a quiet and strong heart.” The chronic pneumonia offers reduced resistance to acute infection, and many die of acute pneumonia. Restitution to full health is impossible. The process due to the pneu- moniokonioses is often stayed when not too far advanced. When the pa- tient changes climate and his work, he may live many years. 382 DISEASES OF THE RESPIRATORY APPARATUS The prognosis is often influenced unfavorably by an intolerant stom- ach due to consecutive hyperemia. Persistent evening rise of temperature, with accelerated pulse and loss of weight are'unfavorable, and suggests tuberculosis or some other added infection. Emphysema, when limited, is physiologic, when extensive it adds to the respiratory embarrassment and is unfavorable, increasing the work of the right heart. With bronchiectatic cavities there may be absorption of septic and pyemic organisms, which reduce vitality and lead to serious constitutional disturbances. Uncomplicated non-tuberculous cases have only rarely caused alarm- ing hemoptysis in our experience. Heredity materially influences the in- cidences of the tuberculization of chronic pneumonics. Children of tuberculous parents are handicapped. The prognosis is more favorable in the adult than in children, so far as length of life is concerned. Apex fibrosis is less favorable than is change at the base of the lungs. Persisently rapid pulse, regardless of other symptoms is always ominous, and demands the most cautious search for its cause; usually the complication of which it is an expression is serious. Reference Juergensen. Ziemssen, Handbuch der spec. Path. Therapie. 1877. 4. Emphysema {Pulmonary Emphysema) Emphysema is a condition in which the air cells are abnormally dilated and the lung enlarged. Surgical emphysema, the escape of air into the pulmonary walls, following injury or surgical operation is not included in my consideration of this subject. Vesicular or pulmonary emphysema may be either (a) Compensatory (b) Hypertrophic (c) Atrophic. (a) Compensatory emphysema Compensatory emphysema develops when after collapse of lung tissue or extensive consolidation, unaffected portions of the lung assume increased function and till the void. With atalectasis associated with bronchopneu- monia, chronic pleurisy, adhesions, and with fibroid overgrowth—chronic interstitial pneumonia—large and chronic pleural effusion, pyopneumo- DISEASES OF TI1E LUNGS 383 thorax and pneumothorax, compensatory lung changes including em- physema follow. The prognosis depends entirely upon the ability to influence the primary condition; once this is removed the lung accomodates itself, and function is practically normal. The discouraging feature is the inability to influence the underlying process. Each case naturally demands separate consideration (See separate sections). Most forms of emphysema are of the mixed type; there is enlargement of the lung, the alveolar walls are dilated and the interstitial tissue is more or less atrophied. Emphysema is relatively frequent. Frankel found positive evidences of emphysema in 5 per cent of 911 post mortems. We found 4 per cent of 6,300 cases of internal disease. Emphysema is not a disease of early life, though children with chronic bronchitis or stenoses of the respiratory tract develop it. It is more frequent after the fortieth year and most frequent in those of advanced age. Men develop emphysema oftener than women. Heredity bears the same relation to emphysema as it does to asthma. James Jackson, Jr., found in Louis’ wards 18 of 28 cases with positive heredity. Emphysema, asthma and chronic bronchitis are usually associated conditions. Bronchitis is the primary lesion in the majority of emphyse- mas. Bronchiectasia and emphysema are frequently present together; in these cases there is preceding and persistent bronchitis also. Fixed thorax is being more and more considered as a cause of emphyse- ma and asthma (favorable for operation). Emphysema is probably dependent upon inspiratory or expiratory stenosis or enfeebled respiratory strength. Emphysema is often found in cases in which there is both in- spiratory and expiratory obstruction. Emphysema is aggravated by occuptions which require heavy work, lifting heavy loads, the playing of wind instruments or the inordinate use of the vocal organs (glass blowing, etc.). When emphysema develops with chronic bronchitis (winter cough) or any bronchial catarrh which con- tinues unrelieved, it is progressive and is likely to lead to secondary circu- latory changes. Chronic bronchitis, “fixed thorax,” and emphysema lead to aggrava- tion of all subjective symptoms during cold and damp weather, also on exertion. Cyanosis and marked dyspnea are evidences of associated heart insufficiency, as a rule. Asthma recurring at short intervals or unrelieved during long periods increases existing emphysema and invites secondary changes. The greater the respiratory weakness (muscular insufficiency of the respiratory muscles) and the more advanced the dilatation of the right ventricle, the less likely are the symptoms of emphysema to improve. (6) Hypertrophic Emphysema 384 DISEASES OF THE RESPIRATORY APPARATUS Persistent cough aggravates existing conditions, showing unrelieved bronchitis or secondary change. Abnormally prolonged expiratory move- ment is evidence of advanced emphysema in the presence of subjective symptoms. Marked change in the shape of the thorax (barrel-shaped thorax) is evidence of chronicity, and with the emphysema remains un- changed. Marked change in the size of the heart, particularly to the right, is present in advanced emphysema, and when associated with myocardial insufficiency is serious. In chronic and extensive cases the area of heart dullness is masked by the overlying dilated and enlarged lung. Chronic nephritis, dilated heart, bronchitis and emphysema is a quartet of conditions at once serious, and while life may be prolonged, is fatal in the end. Hypertrophy of the heart may prove sufficient during many years to carry some emphysematous patients along. In all of these suitable climatic and cautious treatment are important factors in prognosis. Rapid pulse with increasing dyspnea with or without increasing cough is always ominous. Arhythmia after long or short periods of emphysema is unfavor- able and indicates degenerative change. Dropsies either limited or general are always unfavorable. Dropsy is a terminal complication. Relative mitral and tricuspid insufficiency may develop after overtax- ing the heart, or during acute exacerbation of existing bronchitis and asthma. With stimulation and rational treatment these threatening condi- tions often yield; they return on slight cause. Myocardial degeneration is the usual cause of death. Stasis unrelieved leads to liver changes, con- gested kidney with albuminuria, gastrointestinal disturbances and cerebral congestion. Naturally the extent of the existing bronchitis is paramount in most cases, as is also asthma to which we have repeatedly referred. Emphysematous patients who develop pneumonia (bronchopneumonia usually) offer an unfavorable prognosis. I saw one case of fatal pneumothorax follow the rupture of the apex of an emphysematous lung in a post mortem made by Fischer (Frankfurt). In this case other dilatations were seen on the surface with thin walls like tissue paper. The apex was converted into cavities, several of which had ruptured. Emphysema, without serious complication, even with asthma and bronchitis, may not shorten life; such patients may live many years and die of intercurrent disease. Many cases do not advance to involve larger parts of the lung or cause marked secondary heart changes. Inherent weakness of the alveolar walls (Virchow) invites progression. The two factors of greatest importance in the prognosis of emphysema are the be- havior of the bronchial element and the ability to prevent disturbance of heart function with consecutive changes (stasis). Cardiac insufficiency once present, though it may yield to treatment, is certain to recur. Dyce DISEASES OF THE LUNGS 385 Duckworth has reported fatal hemoptysis with emphysema, and Osier mentions “an old emphysematous patient death followed the erosion of a main branch of the pulmonary artery by an ulcer near the bifurcation of the trachea.” (c) Atrophic Emphysema I have considered cases in which there are atrophic changes in con- nection with the hypertrophic form of the disease, and there mentioned that most emphysemata were of the mixed type. The characteristic atrophic form is found in old subjects in whom there is persistent respiratory embarrassment because of great dilatation of the air cells, the disappearance and atrophy of the alveolar walls and consecu- tive cavities. bTo treatment influences these cases.

Gangrene of the Lung Gangrene of the lung is always a secondary infectious process in which the death of either a circumscribed portion of the lung or diffuse areas takes place. Pulmonary gangrene is either embolic (metastatic) or bronchogenic. In my experience I never met but one case in which re- covery followed the positive diagnosis of pulmonary gangrene—it was a sequel of an apex pneumonia in an adult aged 30 years. Lehert claims 6 recoveries in 36 cases; no other clinician has ever approached such en- couraging results. Pneumonia is the most frequent primary infection. Infections in which there are infectious emboli may cause the death of lung tissue. The clinical history of gangrene with the characteristic sputum and odor make its recognition relatively easy. Pneumonia in diabetics invites pulmonary gangrene, which is promptly fatal (See Diabetes Mellitus). Pneumonia with erysipelas or other streptococcus infections has sup- plied several cases in our series, all fatal. Hemorrhagic infarct with sep- tic conditions in nephritis occasionally leads to pulmonary gangrene. The 386 DISEASES OF THE RESPIRATORY APPARATUS gangrene of pulmonary malignancy is one of the factors which increases the septic and typhoid condition and causes death. Thrombosis or embolism of a branch of the pulmonary artery with septic conditions—typhoid, smallpox, pneumonia, or any other malignant infection—may cause gangrene. With all the prognosis is the same. Re- covery is so rare as not to be expected. Wilson Fox found one lung involved in 90 per cent of the cases investi- gated; the right in 54; the left in 36; the lesions were multiple and scat- tered in 22.5 per cent; limited to one lung in 77.5 per cent. Laennec saw 2 cases in his entire practice. We have had 5 cases in 6,300 internal diseases. In over 37 years of active practice we do not recall 10 cases in private and hospital practice. 1.6 per cent is the propor- tion to other causes of death given by several observers (See West, S.). Multiple lesions are not uncommon with gangrene. Rarther reports 8 cerebral abscesses in 49 autopsied cases of pulmonary gangrene—16 per' cent. Gangrene is exceedingly rare with pulmonary tuberculosis. Lung ab- scess and gangrene are occasionally coincident. Infection following pul- monary injury may lead to fatal gangrene. Our patients have usually died after from 5 to 14 days with symptoms of general sepsis and asthenia. In all cases the prognosis should be guardedly given; small abscesses with moderate necrobiosis may lead to recovery. In these cases, as in all who recover, a cavity remains from which there is more or less expectoration, often fetid, and in subacute or chronic cases there may be intermittent septic fever with final multiple foci and death after many weeks or months. Hemoptysis—profuse bronchial hemorrhage—occasionally causes death. Wherever possible, x-ray examination is indicated. With increased surgical technic the future may prove the prognosis of pulmonary gangrene to be more encouraging than it is at present. Aschoff. Pathol. Anatomie, Band ii, Jena, 1913. Fox (Wilson).

Abscess of the Lung Lung abscess is a surgical affection; unless cured by nature’s proc- esses or surgery, it is always fatal. It offers only reasonable hope of DISEASES OF THE LUNGS 387 recovery when superficial and surgically treated. To accomplish its relief by surgical means it must he favorably located, single and circum- scribed. Multiple lung abscesses are almost always fatal. The outcome must depend upon the primary location and extent of the infection as well as the resistance of the patient, his age, and nature’s ability in the absence of surgical intervention to wall off the disease. It may be sec- ondary to pneumonia, pyemia, septicemia, injuries to the lung and chest wall, malignant growths, subphrenic abscess, liver abscess, and hydatid disease of the liver and lung. With pulmonary tuberculosis abscess of the lung often develops, also with pyopneumothorax which condition it may also cause. There are a number of cases recorded which followed the aspiration of foreign bodies, also neck and thorax operations. With malignant growths of the lung or surrounding organs (esophagus) abscess may develop. The pyemic abscesses are of embolic origin and are usually multiple. Perforation of lung abscess may suddenly fill the air cells causing threatening or fatal asphyxia; pyopneumothorax follows pleural perforation and is always a serious complication. In those cases which nature or the surgeon cures, there is gradual improvement of the general and local conditions; the sputum diminishes, the physical signs disappear very largely, and finally x-ray shows cica- tricial contraction or a cavity walled off, or in other cases, a contracted cavity communicating with the bronchial tree. The extent of lung abscess may be studied by means of the Rontgen ray, and valuable diagnostic and prognostic data are thus obtained. 7. Neoplasm of the Lung New growths in the lung are either (a) primary or (b) secondary, (a) Primary Neoplasms.—The primary neoplasms are exceedingly rare and these are usually carcinomatous, taking their origin in a bronchus, usually of considerable size (Aschoff). The occlusion of a large bronchus by the new growth leads to bronchiectasis. Primary cancer soon invades large portions of the lung, offers characteristic physical signs and x-ray picture. In some there is pleural infiltration and bloody effusion. En- largement of supraclavicular, at times axillary, glands may be among the early secondary pathologic changes. The upper lobe is most likely to be the seat of primary carcinoma. Pulmonary gangrene may compli- cate primary carcinoma. Primary pulmonary cancer may originate in the epithelium of the air cells (rarely) or in the metaplastic bronchial epithelium (See Isaac Adler’s splendid monograph for full data concein ing the origin and growth of primary neoplasm of the lung). Aschoff claims that primary neoplasms of bronchial origin often originate in tuberculous cavities. In some of these cases the primary growth is small 388 DISEASES OF THE RESPIRATORY APPARATUS and gives rise to but few symptoms, while distant metastases offer the lead- ing clinical data and cause death; thus, metastatic brain tumor may offer the only prominent symptoms. When the growth is infiltrating (a variety of primary lung cancer), large areas of lung tissue are involved. I base my conclusions upon pathologic data which seem justified, and to these I add my unfortunate clinical experience with primary malignant growths of the lung. Adler, who has given this subject great thought and investigation, concluded one of his chapters as follows: Neglecting in this place all further detail, it may be briefly stated that it is at present the common consensus of opinion, and probably justly so, that the great majority of primary carcinomata of the lungs develop from the bronchi and that a cancer of the lung is, taken strictly, a bron- chial carcinoma; that, on the other hand, a carcinoma starting from the lung tissue itself occurs, but is extremely rare, and is built up, not of flat, but of cylindrical epithelium.” The course of 'primary lung cancer may be either rapidly fatal, acute and galloping, or with symptoms of increasing pressure and bronchopneu- monic symptoms the typical picture of lung cancer is presented; in some cases the features of mediastinal compression are in the ascendency, or the invasion of the pleura may materially influence symptoms and the course of the disease. In none of these clinical types is there hope of recovery. The x-ray examination offers hope of early diagnosis aided by the direct inspection of the bronchi, but unfortunately symptoms are not sufficiently pronounced early to lead either the physician or the patient to take advantage of these refinements of diagnosis. (b) Secondary Lung Growths.—Secondary lung growths may fol- low primary cancer of distant or near organs. The breast and thyroid offer the primary seat of most metastases; they also follow stomach, pan- creatic or genito-urinary growths. Secondary lung growths are usually multiple and infiltrate both lungs. With secondary lung growths, cancer or sarcoma, lymphatic involvement, bronchial, axillary, cervical or in- guinal may develop. The pleural invasion or pressure leads to hydro- thorax, usually bloody. With cachexia, enormously emaciated, and with respiratory embar- rassment, these patients die of exhaustion. Besides cancer and sarcoma, fibroma, lipoma, myoma, teratoma, and osteoma have been found in the lung (Aschoff). References Aschoff. Pathol. Anat. 8. Aufl.,Bd. ii., Jena, 1913. Adler (Isaac).

Pleurisy (a) Fibrinous Pleurisy {Dry Pleurisy, Pleuritis sicca) When dry pleurisy is of primary origin it usually follows in a pre- viously healthy subject after cold or traumatism. Probably but few reach middle life without having at some time had limited pleurisy; in many the process of repair, after the plastic deposit on the pleural surface leads to agglutination of the visceral and parietal pleura, or adhesions, which may or may not give rise to symptoms. Primary dry pleurisy runs its course with but slight constitutional disturbance in from 2 to 7 days. In all of these cases the clinician must bear in mind the possibility of an underlying primary lesion (tuberculosis, pneumonia, etc.). Associated Symptoms.—When pleurisy is secondary to carcinoma, gam grene, traumatism in which there is fracture, or abscess, the prognosis of the plastic pleurisy is of no importance; the primary disease offers the leading data. Pleurisy with croupous pneumonia often adds to the discomfort and may, when severe, influence prognosis unfavorably though the toxemia and extent of the primary disease with the resistance of the patient remain the paramount factors. (6) Serofibrinous Pleurisy {Pleurisy with Effusion) We consider tlie tuberculous pleurisies separately (see Tuberculous Pleurisy—Section on Tuberculosis). Many cases considered non-tuber- culous during long periods finally prove to be tuberculous. Besides tuberculous infection serofibrinous pleurisy may depend upon the 'pneumo- coccus, streptococcus, influenza bacillus, typhoid, diphtheria, and a variety of other infections. The majority of pneumococcus pleurisies are pleuro- pneumonic and their prognosis depends upon the virulence of the lung inflammation and all other conditions which we have considered in con- nection with the prognosis of pneumococcemia (See Pneumococcemia). Pneumococcus pleurisy often becomes purulent when it offers a good prognosis, early detected and radically treated (See Empyema). The septic or streptococcic or staphylococcic pleurisies must naturally depend upon the nature and malignancy of the infection as well as the extent of the pleural change, the amount of the fluid, the early recognition of its presence, and a variety of other data which we consider in connection 390 DISEASES OF THE RESPIRATORY APPARATUS with the symptoms and rational treatment. Most influenzal infections in which there is serous effusion are pleuro- or bronchopneumonic. The prognosis depends upon the same factors as are considered with the pre- ceding clinical types. Associated Symptoms.—With typhoid fever, diphtheria, scarlet fever, polyarthritis and nephritis the addition of pleural effusion is always a serious complication, more, because it is evidence of malignancy or severity of the primary disease. Serofibrinous pleurisy associated with abscess, bronchiectasis, gan- grene, pericarditis, peritonitis, purpura and polyarthritis is considered with these conditions in separate chapters. Most pleurisies of childhood are of pneumococcus origin and offer a fair prognosis. The prognosis of serofibrinous pleurisy depends on the nature of the primary infection, the associated lesions in other organs, the height of the fever and tissue degeneration, the mechanical effect of the effusion, the effect of all upon the circulation, the early diagnosis and rational treatment. High temperature persisting with effusion particularly after early aspiration, with or without repeated chill, leads to the suspicion of puru- lent change. The height of the temperature offers no clue to the nature of the infection. Fall of temperature or decided remissions before aspira- tion may in most cases be interpreted as indicating a mild course. Slight temperature persisting after aspiration is not unusual, neither is it unfa- vorable. In uncomplicated cases we have expected the temperature to fall to or near normal in seven days after aspiration. Persisting tem- perature after the seventh day with increase of fluid and good pulse is not unfavorable in the non-tuberculous cases. In cases which have been considered non-tuberculous, continued temperature, physical signs of fluid, rapid pulse, with or without night sweats, the chances favor an unrecog- nized tuberculosis. Gastro-intestinal symptoms are usually present and yield with the relief of the pleural pressure. Cough persisting is sug- gestive of unrelieved pressure, associated bronchitis, or lung involvement. The severity of pain during the early hours does in some cases indi- cate the depth and extent of the pleurisy. This is not to be accepted with- out considering the possibility of exceptions. Increase of urinary secre- tions, at times polyuria, is favorable and denotes absorption of fluid unless there is proof to the contrary of its dependence on other factors. Blood pressure in favorable cases is not materially changed from the normal. Decided fall is unfavorable. Emaciation is to be expected, but loss of flesh after radical treatment, failure to enter upon a satisfactory convalescence is indicative of associated complication, should lead to thor- ough investigation and suggests the possibility of tuberculous complication. The amount of effusion is not an expression of the malignancy of the infection. There are cases of malignant infection in which the effusion DISEASES OE THE PLEURA 391 is not large; on the other hand, the less malignant infection may be asso- ciated with large exudate. There is no rule. Associated collapse of lung (atelectasis) with weak heart is unfavor- able. Grocco’s triangle is usually present with most fair sized effusions; it is of diagnostic, not of prognostic value. Encapsuled effusion may remain unrecognized longer than free fluid in the pleural cavity, and convalescence is therefore correspondingly retarded. The average favor- able serofibrinous pleurisy runs its course to a favorable termination in from 3 to 4 weeks. The fever gradually falls, the heart strength increases, the physical signs improve, the dullness or flatness does not disappear entirely either after aspiration or absorption, but in the course of several months return of normal percussion note is to be expected. The return of the friction sound after its original disappearance is fa- vorable, for it indicates absorption or removal of fluid. In favorable cases the deformity of the thorax which follows from adhesions and neglect of proper treatment can be favorably influenced by pulmonary gymnastics and climatic change. The former alone, in primary non-tuberculous cases is sufficient. Persistent dyspnea with or without weak myocardium in rationally treated cases is unfavorable and demands thorough search for its cause. In cases which promptly lead to adhesions and in which the lung is com- pressed and bound, unable to expand, there will be a long period before there is compensation. In these cases mechanical treatment (pulmonary gymnastics) often leads to brilliant results, but patience and perseverance are necessary. The unfavorable pleurisies are those which have been neglected, in which the lung and other organs are misplaced, in which the heart is weak, the fever uncontrolled, the absorption slow, the improvement unsatisfac- tory after aspiration, and in which there is the picture of sepsis. In spite of these unfavorable features a number of these cases in which tuberculization does not follow, recover fully with more or less misshapen chests. Delirium and other evidences of involvement of the sensorium, with rapid pulse and typhoid condition, are characteristic of the graver pleu- risies. But few cases run an absolutely acute course. General Considerations.—The sudden deaths reported by some are ex- ceedingly rare. In our practice we never met but one sudden death from serofibrinous pleurisy. In that case the effusion had not been detected during many weeks; preparation was being made for aspiration during which the patient suddenly expired without preceding alarming heart weakness. Double serofibrinous pleurisy is exceedingly rare: most of these cases are in reality hydrothorax dependent upon circulatory or other obstruction. Interlobular pleurisy is more frequent than has been heretofore sup- 392 DISEASES OF THE RESPIRATORY APPARATUS posed. The diagnosis is easily made, as is that of all serofibrinous pleurisies by x-ray examination. Interlobular pleurisy (involving the surfaces between two lobes) may cause considerable malformation and troublesome adhesions, and unless the possibility of such encapsuled serofibrinous effusion is considered in the absence of the Rontgen rays the diagnosis will not be made. We refer to interlobular purulent pleurisy in the consideration of empyema. Fraenkel and Dietlen have done yeo- man’s service in this field by giving convincing clinical and pathologic data. The prognosis of interlobular pleurisy is favorable. The prognosis of serofibrinous pleurisy of early life (children) is not unfavorable. Pleurisies limiting themselves to the diaphragm, the mediastinum and the pleuritic thickening and effusion of pleuropericarditis (polyserositis) are not primary, and their significance must be separately considered with the associated conditions (See Polyserositis). The differential diag- nosis of the tuberculous and non-tuberculous pleuritides is enormously assisted by the leukocytic blood count. We have invariably found low white counts in our tuberculous cases and have prognosticated accord- ingly. The lymphocytes are relatively increased with tuberculous pleurisy as in other forms of tuberculosis. The average white count in non- tuberculous pleurisies is between 10,000 and 15,000. Staelielin reports 13 deaths in 400 of serofibrinous pleurisy. In those previously depleted by disease (infection) with resistance lowered, the prognosis is correspondingly influenced. The influence of early recogni- tion and timely aspiration on prognosis is paramouunt. Complicating pulmonary embolism and thrombosis are among the rare but fatal accidents. Chronic interstitial pneumonia follows only those cases which lead to chronic pleurisy. References Bain. Textbook of medical 'practice. London, 1904. Dietlen. Ergebnisse der inneren Med.

(c) Purulent Pleurisy {Empyema—Pyothorax) The larger number of purulent pleural effusions are secondary, and most of these are found with the various types of pneumonia, either during the period of active inflammation of the lung or as a sequel fol- lowing in the course of a fewT days or weeks. DISEASES OF THE PLEURA 393 The more virulent types of empyema are those in which the bacterial invasion is greatest, in which the accumulation has remained unrecog- nized or neglected and time has been given for burrowing and distant infection, secondary pus accumulation in kidney, spleen, or other organs— occasionally purulent meningitis. The prognosis is also materially influ- enced by the previous condition of the patient, the character of the pri- mary pneumonia, its extent and the behavior of the cardiovascular and renal organs, and the ability of the patient to resist disease. Associated Symptoms.—Either typical or atypical pneumonias may have pus accumulation added. The more frequent are pneumococcus infections, but influenzal or streptococcus pneumonias are likely to suffer from this complication. In all, the prognosis is materially influenced by the added lesion hut it may be positively concluded that in all, the early recognition of the pus, and its prompt removal, in the absence of asso- ciated depressing conditions, particularly if the primary disease has run its course, allows a reasonably good prognosis to be given. Pneumococcus empyema offers a more favorable prognosis than do any of the other infections above mentioned. Abscess of the lung associated with empyema offers a less favorable prognosis than does the latter alone. Yet in these cases in children and in adults during the active years of life, while the condition must be con- sidered to be serious, the prognosis is not absolutely bad. I have the records of a number of cases of this kind in which, after a slow conva- lescence and long drainage, the patients have made a complete recovery, though with misshapen and sunken thoraces which finally improved under well regulated and long continued pulmonary gymnastics, in favorable surroundings. Empyema with metastases, occasionally found with puerperal fever, erysipelas, diphtheria, traumatism, tonsillitis, endocarditis, either benign or malignant infections of the ivalls of the thorax, or tuberculosis with or without pneumothorax, offers a very grave prognosis. The prognosis is unfavorably influenced by a rapid pulse if this does not yield within a reasonable time to the radical treatment of the empyema. Constitutional symptoms, such as fever and delirium, the former high and persistent, with or without chills, are found in the more malignant types of the disease; if they do not yield after rational treatment in a. reasonable time argue against recovery. Active delirium with rapid pulse and high fever in the acute period of pneumonia with pyothorax is suggestive of malignant infection and justifies an exceedingly grave prognosis. General Statements.—Spontaneous resorption of pus from the pleural cavity is not likely to occur. It certainly does not deserve to be considered in the prognosis or treatment of the typical disease, and he who depends upon it to the exclusion of radical methods of treatment is adding to the 394 DISEASES OF THE RESPIRATORY APPARATUS dangers of his patient, reducing the chances of restoration to health, and is inviting rupture into lung or bronchus, deformity—usually irreparable —or death from exhaustion with general infection and possible amyloid changes. Empyema necessitatis offers a poor prognosis for final complete func- tionating ability of the lung. Its ravages are often difficult of treatment, and may continue to prove a drag upon the patient during his entire life; they leave an avenue for future infection and almost continuous discomfort, besides the possibility of amyloid and other degenerations. In these as in all cases of empyema the great danger of pyemia and sepsis must be considered. In double empyema of pneumococcus origin the prognosis is less favorable than with invasion of but one pleural cavity, but it is still good and the majority of these cases, promptly recognized and treated, recover. With the more malignant and far-reaching double empyemata of strepto- coccus origin the condition is graver; death usually follows, the dura- tion depending upon associated conditions. It is often surprising to note how promptly patients with empyema, with all appearances of serious illness, recover after the free evacuation of the pus. The prognosis during early life is good in the large majority of cases. It is safe to place the recoveries above 90 per cent. Even during the first two or three years of life these figures are justified. In the adult during the active years of life, uncomplicated empyema offers an exceptionally good prognosis. Complications above mentioned must be considered. In old age, beginning with the fifty-fifth year of life, the prognosis is less favorable; fortunately the number of cases of empyema at this time of life is strikingly small. The time of the complication is of great importance in prognosis. At the height of pneumonia of whatever bacterial type, the prognosis is less favorable than after the crisis. If in these cases there is cerebral inva- sion, if alcoholism, nephritis or arterial degeneration, or chronic metabolic fault (diabetes mellitus, gout, etc.), the prognosis is grave, and death follows promptly as a rule. Recently Gerhardt, D., has described a type of empyema to which he refers as parapneumonic empyema. This condition is as a rule (I) asso- ciated with pneumonia at its height, (II) is of limited extent, (III) offers a favorable prognosis and (IV) the pus is remarkably free from micro- organisms. The larger number of these cases will remain unrecognized, for the pus accumulation has been found so small and the added symptoms so few that it appears to the writer that its diagnosis is uncertain. Ger- hardt claims however that in the Basel Clinic in 4-J years he recognized 20 cases of parapneumonic empyema in 300 cases of pneumonia, while in Wurzburg in 95 cases he found but 3 cases. DISEASES OF THE PLEURA 395 If we accept the contentions of Gerhardt that such limited pus accu- mulations are frequently present with pneumonia, and adopt his charac- terization of the complication as parapneumonic empyema, we are justified in concluding that the condition does not materially influence the prog- nosis of the primary disease and that its own prognosis is good.

(e) Chronic Pleurisy There are cases of pleural effusion which persist during many months, which after the chest is emptied by aspiration return; they remain non- purulent. Most of these in the end prove to be symptomatic and not true primary pleurisies. Some are tuberculous from the beginning and some of these may finally yield to time or radical surgical treatment; in others the fluid is finally absorbed; a number of cases are finally compli- cated by lung involvement and die of general tuberculosis. There are cases of a chronic character in which subjective symptoms and pleural thickening persist after pleuritis sicca. Such patients continue more or less out of health; they have some respiratory embarrassment, chronic cough, at times no cough at all—while pleuritic pains recur with the change of weather. All of these symptoms may follow any form of pleurisy including empyema, and are of no grave significance. Another class of cases is that in which pleurisy causes gradually increasing 'pro- liferative changes, resulting in thickening of the surfaces and extension to the interstitial tissue of the lung with resulting fibroid pneumonia, always chronic (See Chronic Interstitial Pneumonia). These cases pri- mary pleural, may extend so slowly as to cause but few symptoms or little inconvenience during many years; the patients recognize their limitations and are worse during the winter and damp weather. Tuberculization is not uncommon. Chronic pleurisy ivith multiple adhesions is frequently found post mortem without having caused symptoms during life. There are chronic pleuritides in which adhesions and proliferative lung changes lead to emphysema, bronchiectasis, and dilated heart. With increasing heait weakness dropsies may develop; also albuminuria and death results from exhaustion. It not infrequently happens that pleural effusions are encysted, form- ing small or large serofibrinous cysts. The prognosis of these, when 396 DISEASES OF THE RESPIRATORY APPARATUS primary, is good. X-ray examination when possible should be used to determine the location and extent of these. Hemorrhagic pleurisies are usually symptomatic of either carcinoma or sarcoma of the pleura or lung, malignant infection, hemorrhagic in- farcts, terminal nephritis, tuberculosis or other grave primary lesions. These are therefore not true pleurisies. In all the prognosis is bad. 2. Hydrothorax The transudation of non-inflammatory fluid in the pleural cavities is secondary, and purely symptomatic. It is usually an expression of circula- tory insufficiency or compression and a part of general dropsy with myo- cardial insufficiency. Circulatory obstruction or insufficiency leading to hydrothorax may fill one or both pleural cavities. With heart lesions the hydrothorax is often unilateral; renal hydrothorax is almost always double. Causes.—Carcinoma, grave constitutional anomalies, the graver ane- mias, Hodgkin’s disease, pericardial adhesions and growths of the lung and pleura may by pressure cause hydrothorax. The prognosis of all these conditions is bad. Associated Symptoms.—With heart lesions there may be material tem- porary improvement but hydrothorax is usually a terminal complication and when persistent during several weeks, without relief of the myocardial weakness, death is not long postponed. Ascites and hydrothorax are usually present at the same time. 3. Pneumothorax (a) Hydropneumothorax (b) Pyopneumothorax Air in the pleural cavity is symptomatic. Pneumothorax is rarely present without either serum (a) hydropneumothorax, or pus (b) pyo- pneumothorax. Pneumothorax results when the pleural cavity is in com- munication with the external air; hence in the larger number of cases there is, either because of disease or trauma, perforation of the lung. In consid- ering emphysema we call attention to the rupture of superficial emphyse- matous cavities; in our consideration of tuberculosis we also mention this accident. With whooping-cough, in rare cases, rupture of the lung may occur during a violent fit of coughing. Abscess and gangrene of the lung superficially located or burrowing, empyema rupturing into the lung, the breakdown of malignant nodule (carcinoma or actinomycosis or sarcoma) or perforation from the stomach through the diaphragm, perforation of the esophagus, aneurismal rupture, abscess of the liver, injuries to the DISEASES OF THE PLEURA 397 chest wall, following the use of the aspirator needle, and in occasional cases rupture of the healthy lung during sleep or on only slight exertion, may all cause pneumothorax. We have recently received the history of a pneu- mothorax in an apparently healthy young man while playing billiards. These accidents do not always cause inflammatory changes (pleuritis) but, as a rule, they do. S. West believes that 90 per cent of all pneumothorax is secondary to the rupture of a tuberculous cavity or the breakdown of superficially located tubercle. Statistics.—Osier mentions the “spontaneous development” in pleural exudates of the gas bacillus (B. aerogenes capsulatus, Welch). Emerson reports 48 cases of which 22 were tuberculous, 6 due to trauma, 10 of aspi- ration, 2 spontaneous, 2 with bronchiectasis, 2 abscess of the lung, 2 due to empyema, 1 gangrene of the lung, and 1 abscess of the liver. Saussier’s statistics show 62 per cent due to tuberculosis. Of 131 cases he found 29 due to empyema. General Considerations.—The statistics of Walshe correspond with those of S. West. West, considering the possibility of rupturing a healthy lung “by any force which respiration can bring to bear upon it” concludes that it is possible, and cites pneumothorax resulting from whooping-congh and straining during labor. The direct results of pneumothorax are the collapse of the lung, and the displacement of organs. The danger from collapse of lung tissue which makes it useless is great, particularly when the breathing surface of the opposite lung is lowered by infiltrating disease. Besides the collapse of the lung on the side of the pneumothorax, the op- posite lung suffers more or less from collapse, contains a reduced quantity of air, and “a smaller aerating surface on which the blood vessels are ex- posed to the air.” With these conditions there is “embarrassment of the circulation which pneumothorax causes” (West). Because of these facts the greatest danger of pneumothorax immediately follows the perforation, within the first hour, and West contends that “the immediate prognosis improves with every hour that life is prolonged.” The ability to accommodate the lung function to the suddenly changed respiratory conditions, and the condition of the heart and the opposite lung, are important factors in framing the early prognosis. Naturally the prognosis is best when the lung has been previously normal. In cases of advanced tuberculosis the early symptoms may be largely cardiac and less pulmonary. Perforation leading to pneumothorax without advanced infil- tration, or in the apparently healthy because of sudden change of respira- tory conditions leads to greater respiratory embarrassment. In both, the ability of the heart to come to the rescue largely influences the prognosis. In some cases of tuberculosis where the process is not far advanced, pneu- mothorax without causing hydro- or pyothorax, may have a salutary effect, just as artificially produced pneumothorax in properly selected cases proves beneficial in a proportion of cases. 398 DISEASES OF THE RESPIRATORY APPARATUS Sudden cardiac insufficiency with collapse is the leading danger of pneumothorax. Pneumothorax is not of necessity a complication of the more advanced cases of tuberculosis; the rapidly advancing cases are most liable to perforation. Much depends upon the local change at the point of rupture; it may be extensive there, but limited elsewhere. Persisting dyspnea is always significant of danger; with its relief and a fairly strong heart the immediate danger is decreased. It is possible for the perforation to seal itself and the air to absorb, if effusion is absent. Naturally the primary tuberculosis may be so far advanced as to prove the immediate cause of death. Additional Statistics.—West in a series of 101 cases was positive of the duration in 39 and knew approximately in 37. Of the 39 cases, 10 patients died within the first 24 hours; “2 within 20 minutes and 30 min- utes respectively of the attack; the other 8 within a few hours.” “18 had died by the end of the first week, and 21 by the end of the fortnight ; to which may be added 8 more cases, in which the duration cannot be quite determined, though it was certainly less than 14 days, making thus 29 out of 39 cases which were fatal within the fortnight, i. e., nearly 75 per cent. In other words, 3 out of every 4 cases.” Six more died within the second fortnight. “Of the 35 cases in which the duration was uncertain, 9 were admitted with pneumothorax and died in the hospital; 10 developed pneumothorax in the hospital, and left at varying dates after the attack, some of whom were known to have died subsequently at their own homes; while 18 patients were admitted with pneumothorax and left with it. Of this second group, taking all the cases together, 10 died within the first month, 8 more within the second, and 2 more within the third—making 19 in all.” “Taking the two series together of 74 cases, 45 died within the month, i. e., 60 per cent; 9 more died within the second month, making 71 per cent.” Seven were alive at the end of the third month, one at the end of the fifth, one at the end of the ninth. West reports 20 cases under his immediate care of which 12 died and 8 recovered—60 per cent mortality. The records of St. Bartholomew’s Hospital for 14 years give the same mortality. Special Considerations.—Pneumothorax due to empyema—rupture through the chest wall or into the lung with empyema necessitatis—offers a more favorable prognosis than does tuberculosis or other pneumothorax. The clinician in offering prognosis must consider as suggested by West: (1) “The immediate risk to life.” (2) “The possible duration of life.” (3) “The chances of ultimate recovery.” (1) The Immediate Risk to Life.—We have called attention to the greater danger immediately following the perforation. In deciding on DISEASES OF THE PLEURA 399 the outcome, the dyspnea and circulatory obstruction, as shown by dyspnea, the condition of the opposite lung, the resistance of the patient and the underlying (primary) cause are the leading factors to be considered. (2) The Possible Duration of Life.—The length of the patient’s life depends largely on the extent and nature of the primary lesion, the heart condition, the resistance, the character of the effusion and the complica- tions. (3) The Chances of Ultimate Recovery.—We have seen recoveries in our series. We are watching a physician who almost two years ago after a number of years of latent tuberculosis (supposed cured) without warning, developed threatening pneumothorax. He is living, engaged in literary work, walks well and seems to be making a slow convalescence under favor- able climatic conditions. West places the average of recoveries at 10 per cent. The St. Barthol- omew’s statistics yield over 25 per cent. West’s own statistics in “20 cases show 5 complete recoveries, in 3 the recoveries from pneumothorax were complete, but the patients died subsequently of phthisis; and in 3 others recovery was incomplete. Besides these, I have seen one other case in consultation in which recovery was complete and the patient remained well for many years.” Without effusion the prognosis is always more favorable. Purulent effusion (pyopneumothorax) offers the most unfavorable prognosis. X-ray examination will prove of great assistance in showing the extent of the primary deposits and the amount of effusion and displacement. References Emerson. Johns Hopkins Hospital Reports, xi.

Mediastinal Diseases Because of the relative importance of the organs within and in close relation to the mediastinum, the fact that most mediastinal lesions lead to pressure, the prognosis of all mediastinal lesions is grave. The leading mediastinal tumors are: sarcoma—these may arise from lymphatic glands, the thymus or cellular tissue (Woodwark, Aschoff and Mueller), secondary cancer, lymphadenoma (glandular), dermoid and hydatid cysts. 400 DISEASES OF THE RESPIRATORY APPARATUS Associated Symptoms.—The pressure symptoms and physical signs with all of these conditions are positive, as they are also with aneurism, specific lymphadenitis, abscess and emphysema following injury or per- foration of surrounding organs. Tuberculous glands may lead to suppura- tion and pressure. Hare made an exhaustive study of the diseases of the mediastinum, including 520 cases. He found 134 cancers, 98 of sar- coma, 21 lymphoma, 7 fibroma, 11 dermoid cysts, 8 hydatid cysts; lipoma, gumma and enchondroma. Sarcoma is oftener primary than cancer. The prognosis of mediastinal growths is absolutely bad. With increas- ing dyspnea, cyanosis, edema and heart insufficiency these patients often die after weeks of wretchedness. The x-ray pictures make it possible to watch the growth, locate it and recognize the changed relations of the included and surrounding organs (Rieder, Ilolzknecht). Mediastinal abscess may perforate; it has been the cause of death with erysipelas or it may develop without known cause. Mediastinitis which is suppurative is always a serious disease. Recovery from abscess may be expected in about one-half the cases. Hare says 40 per cent. Acute thymus death has been separately considered. Pressure from an enlarged thymus gland, if great, impinges on the mediastinum with fatal result, if not relieved at once. We have seen several cases in which death followed a few days of suddenly increasing mediastinal pres- sure with Hodgkins’ disease and lymphatic leukemia. The heart changes materially influence prognosis with all mediastinal displacement; usually the displacement is to the left. Venous stasis is common and in cases which are terminal, the engorgement of the face and arms, one or both, w-ith dyspnea and deep cyanosis tell of the approaching end. Tumors which press on the trachea and esophagus show their pro- gression by increasing stridor and dysphagia. Hydrothorax and palpable nodules, enlarged supraclavicular glands all aid diagnosis and prognosis. Cachexia is often extreme with mediastinal malignancy. According to Mueller, Fr., death follows in about one year in the average case. The course of the disease depends upon the nature and rapidity of the growth. Blood counts particularly leukocytic counts will often prove of value in differentiating thyroid, thymus enlargement and malignant growths. With thyroid or thymus pressure there are the blood changes mentioned in our separate consideration of disease of the ductless glands. The increased lymphocytosis (30 to 50 per cent) with these is of great diagnostic and prognostic value (See Thyroid and Thymus Disease). Displacement of the mediastinum due to pleural or pericardial effusion may prove fatal unless promptly relieved. Hare includes 6 cases of hematoma in his series of 520 cases of mediastinal disease. Most hema- toma of the mediastinum are of traumatic origin and are exceedingly grave. The extent can be decided by x-ray examination, but the subjective symp- toms will offer the best guide for the forecast. If dyspnea and cyanosis DISEASES OF THE PLEURA 401 are relieved or improving, if the pulse is correspondingly better there is hope of ultimate relief unless there are associated unfavorable conditions.

Arteriosclerosis (Arteriocapillary Fibrosis, Atherosclerosis, Atheromatous Degeneration, Endarteritis chronica deformans, Endarteritis chronica nodosa, Arterial Degeneration) Arteriosclerosis is a progressive nutritional disturbance of the arterial wall, with swelling, thickening and sclerosis of the intima primarily, in- crease and degeneration of cellular elements, partial necrosis and calcifica- tion, either diffuse or nodular, in which all coats are finally involved; the media more particularly when the arteries of the extremities are affected. There is in advanced cases, change of a productive character in the adventitia (peri-arteritis). This definition of Marchand is almost universally adopted by clinicians and pathologists and at once demon- strates the possibility of either limited degeneration, or what is more fre- quently found—almost universal invasion of the arterial tree with con- secutive changes in many organs. The correct conception of the causes and nature of the pathologic processes included in arterial degeneration proves the complex character of the lesions in the individual case, that the prognostic and clinical problems are among the most complicated and obscure in the whole field of internal medicine, and that the dictum of Bimce finds profitable application in connection with our study of this dis- organizing process, in which he holds: “The best prognostic use to make of symptoms and signs is indirect; not to value them individually, but to diagnose by them the cause and nature of the pathologic process, and then to frame our forecast by these.” Arteriosclerosis furnishes the fundamental morbid processes in the larger number of deaths after the fortieth year. Arteriosclerosis of the heart, kidney and brain is the cause of 22 per cent of all deaths after the fortieth year of life. Advanced arteriosclerosis is synonymous with old age. Whenever 402 ARTERIOSCLEROSIS 403 present, the changes are suggestive, for we find the skin altered and wrinkled, the parenchymatous organs and muscles atrophied, the hones show trophic changes and fracture easily and the mental status is below par. The pressure in the aorta and peripheral vessels in the aged is not necessarily the same, it is higher in the ascending aorta and in conse- quence is lower in the periphery. The increase of cardiovascular disease during the past two decades has been recognized by all clinicians. This increase is greater the farther we are separated from hospital practice. Of 5,708 cases of internal disease seen in our private practice during the past seven years of which we have full records, there were 623 cases of marked and advanced arteriosclerosis 10.8 per cent, 101 cases of angina pectoris, 1.77 per cent, and 110 cases of chronic interstitial nephritis, 1.9 per cent. The change is appreciated when we quote from a long-hand written report of the lectures of Benjamin Rush delivered over 125 years ago, in which that experienced and busy clinician makes the statement that he had seen but “one case of angina pectoris” and mentions the name of another Philadelphia physician who had also seen but one case. The gravity of arterial degeneration is shown further by the increase of other heart lesions directly dependent upon the same process. Thus in an analysis of our cases, we find 4.2 per cent showing evidences of degen- erative endocarditis; (in contradistinction to inflammatory) 4.7 per cent of aortic obstructive and degenerative lesions of the aorta, and 8.6 per cent of myocardial degenerations. The study of our material justifies the conclusion that hurry, worry and excesses are at the bottom of the majority of our cases; the stress of modern life, syphilis, and the enormous influence of heredity are among the leading factors with which we must reckon. In all cases there is a period of hypertension, either recognized or un- recognized which precedes the fully developed symptoms which are directly due to arteriosclerosis—to this we will again refer. There is a physiological hyperplasia of the intima during early life. For purposes of diagnosis and prognosis we consider the separate artery as an organ, a part of the body which has positive functions to per- form; its task is not single but multiple; the performance of its daily undisturbed work is attended even during the earliest years of life with a compensatory deposit for the preservation of these organs and the con- tinuity of the circulation. As soon as this physiological hyperplastic change of the intima because of age, overwork, strain, toxemia, or from any other cause is forced into a stage of hypertrophy, we have the beginning of arteriosclerosis. The leading factors which influence prognosis are the following: 404 DISEASES OF THE CIRCULATORY APPARATUS 1. Age Arteriosclerosis is present more or less advanced in most subjects who have lived beyond the fiftieth year. If the arterial tree is subjected to critical microscopic examination this fact is fully established. Arteriosclerosis may persist for years without giving rise to a single symptom, without in any way interfering with the comfort of the indi- vidual ; it is well borne when it is associated with the tolerance and com- pensation that are expected in the subject advanced in life. These favor- able conditions do not prevail during early life. Young subjects do not bear arteriosclerosis well; in these, evident and palpable lesions are not long present without marked evidences of progres- sion and the development of organic lesions in vital organs, unless the process is promptly controlled by proper treatment. If of syphilitic origin and not far advanced the artery may and often does yield to intensive treatment. No person is too young or too old to be thoroughly searched for arte- rial change; the prognosis so far as tolerance and length of life are con- cerned is unfavorable in the younger subjects. Romberg in 174 male patients, excluding all juvenile arteriosclerosis at the Marburg Klinik found arteriosclerosis: Between the 20th and 29th year in 4.89 per cent. Between the 30th and 39th year in 14.28 per cent. Between the 40th and 49th year in 29.67 per cent. Between the 50th and 60th year in 41.55 per cent. Between the 60th and 69th year in 57.77 per cent. Among 703 females: Between the 30th and 39th year in 0.78 per cent. Between the 40th and 49th year in 6.1 per cent. Between the 50tli and 59th year in 34.25 per cent. Between the 60th and 69th year in 52.00 per cent. Severe arteriosclerosis in young subjects involving the aorta and other vessels are not uncommon. Andral, Pischl and Chiari, found in all sub- jects examined in Prague between 2 and 25 years of age 48.7 per cent with beginning evidences of arteriosclerosis in the intima of the aorta. When arteriosclerosis is the prime cause of death, it is likely to claim its victims during the productive years when they ought still to be able to continue their occupations; as Bruce has said “when work ought to be still carried on in the interest of the family and country, at an age when a man’s reasonable ambitions, as a rule, have not been attained.” Grass- man offers the following data which corroborate our conclusions: Of 151,- 083 who died in Germany 13,247 had cardiovascular lesiohs, including cases of cerebral apoplexy. Prom 15 to 30 years he found diseases of the ARTERIOSCLEROSIS 405 circulatory organs the cause of death in 7 per cent; between 30 and 60 years 14.5 per cent of all deaths were due to the same causes. In Bavaria in 1907, 17,000 died of diseases of the cardiovascular system and 7,000 of cancer, thus two groups were responsible for 25 per cent of all deaths. 2. Heredity The influence of family history on the prognosis of arteriosclerosis is paramount. In subjects burdened with the family history of arterio- sclerosis there is progression of the degeneration on slight cause. Histories in which one or both parents and several of their children have died of coronary disease are not uncommon; neither are the instances of cerebral hemorrhage in many members of a family at almost the same age unusual. The appreciation of the influence of heredity on prognosis, interpreted by the physician and the patient, may if heeded, lead to rational cautious living and appropriate occupation, which will often postpone unfortunate tendencies and thus prolong life. 3. Syphilis We have elsewhere considered the influence of specific infection on the arterial tree (See Syphilis of Arteries) and will also consider aneurismal dilatations which are often of specific origin, separately. It is a fact that arteriosclerosis (arteritis specif ca), of syphilitic origin when early recognized is amenable to treatment and may yield after severe and threatening subjective symptoms. 4. Worry and Stress The arteriosclerosis which follows long continued worry and stress, par- ticularly with unfavorable family history, is likely to advance insidiously, to involve vital organs (heart and kidney), before subjective symptoms are sufficient to bring the patient to the physician. The obstruction in the arterial tree is shown by persistent hypertension and hypertrophy of the left ventricle, all of which make the prognosis grave. It is surprising, however, to note how in individual cases, if the patient is removed to a favorable environment, where rest, relaxation with freedom from care and rational living obtain, he improves, and how his life may be prolonged. With the baneful factors continuing, such lives are promptly ended, usu- ally with evidences of added myocarditis and chronic interstitial nephritis. (See Occupation in this chapter.) 5. Alcohol Alcohol is directly and indirectly a factor of the greatest importance in the causation and prognosis of arteriosclerosis. Alcoholics are as a rule 406 DISEASES OF THE CIRCULATORY APPARATUS careless of their health, some are inordinate eaters, some have perverted appetites, others to tempt their appetites use deleterious condiments (pep- per, etc.) ; they eat at irregular hours; while alcohol itself may not pro- duce hypertension and arterial change, the productive changes wrought in liver, heart, brain and kidney, with the factors above mentioned lead indi- rectly to arteriosclerosis and the inclusion of the changes in the vital or- gans which lower the resistance of these subjects and lead to death. The contention of Richard Cabot that alcohol does not cause arteriosclerosis based on the examination of the arteries of alcoholic inebriates has not been generally accepted by the profession; as we have intimated we know that a large number of alcoholics die of cardiovascular disease, particu- larly arteriosclerotic processes and must accept that fact as proved in framing a forecast. Ilarlow Brooks’ report of 400 autopsies and the clin- ical evidences obtainable are sufficient to establish the influence of alcohol on arterial disease. The following is the table compiled from Brooks’ statistics: Artery. Cases. Etiological Factors. 400 Alcohol, 149; among laborers, 115; nephritis, 51; syphilis, 38; old age, 38.

Lead Lead poisoning leads to hypertension, arterial thickening, chronic ne- phritis and when advanced offers an unfavorable prognosis for Restitutio ad integrum. When detected early, and the patient is removed from the atmosphere of lead, the prognosis is not unfavorable, though the arteries remain permanently altered. ARTERIOSCLEROS1S 407 7. Tobacco Lauder Brunton says of the influence of nicotin, “The rise of blood pressure is so great that I have never seen it equaled after the injection of any drug, with the exception of suprarenal extract. The rise is due to contraction of the arteries. The ultimate effect is to increase the rapidity of the heart.” I am fully satisfied that in many cases tobacco is among the cause of arteriosclerosis, that it aggravates existing hypertension and arterial degeneration, that unless used in moderation it is injurious to adults and that for growing boys it is “distinctly harmful.” The use of tobacco in the presence of hypertension and arteriosclerosis acts unfavorably on the organic process. 8. Infection The influence of infection in causing hypertension and arterial change has been noticed and studied by most clinicians. Thayer and Brush ex- amined 4,000 consecutive cases admitted to the Johns Hopkins Hospital and found changed arteries in the percentages noted of the patients under fifty years of age who had been the subjects of the following factors: After scarlet fever, radials palpable in 16.4 per cent. No causal factors with palpable radials in 16.5 “ “ Pneumonia, radials palpable 17.0 “ “ Diphtheria, radials palpable 17.0 “ “ Malaria, radials palpable 20.0 “ “ Typhoid fever, radials palpable 26.0 “ “ Rheumatism, radials palpable 34.0 “ “ Alcoholics, radials palpable 46.8 “ “ Hard work, radials palpable 57.5 “ “ Added infection of any kind in subjects with pronounced arteriosclero- sis is always serious and adds enormously to the danger. Pneumonia is almost uniformly fatal in the presence of advanced arteriosclerosis, while typhoid fever, sepsis, rheumatism, and erysipelas also offer unfavorable prognoses. With some acute infections in the presence of arteriosclerosis the pulse may continue slow, full and reasurring during the first forty-eight hours (particularly with pneumonia), but soon there is a break, the blood pres- sure falls and the heart becomes insufficient. 9. Occupation Occupation is of paramount importance in the etiology and prognosis of arteriosclerosis. Arteriosclerosis is the result of long continued wear and tear, more 408 DISEASES OF THE CIRCULATORY APPARATUS tear, “which is the result of abuse,” than wear which as Weir Mitchell said is “the result of use.” The busy brain worker, the man of enormous responsibilities, the worker who with his worries is obliged to hurry, whose rest is insuffi- cient, who is wearing his bearings and holding the string taut, is grad- ually but certainly encouraging arterial degeneration, he may work dur- ing months or even years with hypertension, no warning has led him to relax until he has run to a fall and is beyond the stage of hypertension and has fully developed arteriosclerosis. This is the history of hypertension and arterial degeneration as it is found among professional men, includ- ing physicians, lawyers, bankers, brokers, engineers, all occupations which tax the brain and are sedentary. In physicians, the tendency is toward coronary disease. With but one notable exception all members of the Vienna faculty who have died within the past two decades have yielded to coronary sclerosis and myocardial degeneration. In our own country the number of physicians who are claimed by coronary disease or general arteriosclerosis is surprisingly large. Romberg says “Everyone acquires his arteriosclerosis within the circuit which he has taxed most.” There is no more interesting question in connection with the etiology and prognosis of arteriosclerosis than nervous stress. It “winds up the best brains in the community” (Bruce). The combination of “intellectual stress and emotional stress” which characterizes the “strenuous life” is at the bottom of physiological collapse. The early appreciation of the effect of occupation with appropriate treatment during the period of hypertension often does much to relieve the tension and prevent progression to organic change. In these cases the timely detection of a trace of albumin and an occasional hyalin cast is a warning which if recognized may prove life saving. The truth of Romberg’s dictum is proved by the location of the greater changes in the arteries in the different occupations. The brain, heart and kidney vessels show greatest changes in those of sedentary habits—i. e., in brain workers. In workingmen, the arteries of the extremities are most involved. In the wives of farmers the arteries of the legs are the seat of degeneration; among wealthy females we often find the mesenteries involved, often the coronaries, sometimes both. In all, when arteriosclerosis develops rapidly after an unrecognized period of hypertension there is likely to be kidney invasion; this is true of those cases in which there is enormous accentuation of the second pul- monic sound, in which the pulse continues tense, and there are evidences of hypertrophy of the left ventricle. Some of these apparently subacute cases may lead to death within a few months. In the majority, an early appreciation of the effect of occupation on prognosis by the individual, with prudent and cautious self-control, the ARTERIOSCLEROSIS 409 ability to bring appetite to reason, the practice of sobriety, temperance and abstinence, much can be accomplished to prevent the onward march of the degeneration. Benjamin Franklin’s aphorism is applicable, “Against diseases known, the strongest fence is the defensive virtue, abstinence.” 10. Overeating The arteriosclerotic who cannot control his appetite, is unable to con- trol the process which threatens his life. Overeating invites and produces degeneration; it increases it because it throws an extra burden on the heart, vessels and digestive organs. It interferes with metabolism and chokes the furnace to the disadvantage of the cardiovascular system as well as most organs within the domain of the splanchnic and renal vessels. A single error of diet has often ended life which might have contin- ued in comfort during many years. This is particularly true of coronary sclerosis and myocardial degeneration. These are the deaths which are incorrectly attributed to “Acute indigestion” which are increasing with noticeable frequency. 11. Mechanical Factors Mechanical factors have a decided influence on prognosis, the sclerosed artery has been robbed of its elasticity, it is lengthened and abnormally tortuous, it demands auxiliary force (vis a ter go) which in the end may prove insufficient. The ability of the heart muscle to continue to compen- sate for the lack of assistance normally offered by artery and muscle, to which it has been accustomed, naturally influences the prognosis enor- mously. Mechanical strain aggravates existing sclerosis and may lead to rup- ture and sudden death or to aneurism. 12. Chemical and Toxic Factors Chemical and toxic factors unquestionably exert a baneful influence. These may be provocative of hypertension, or when present the continuous poisoning increases the ravages of the process in all directions. The re- tention of wornout material, the results of faulty metabolism, persistent hyperglycemia (Diabetes mellitus), the blood surcharged with uric acid and its products, with gout, the other toxic states which are associated with faulty secretion and excretion, the influence of the ductless glands, particularly the adrenals in throwing their secretions into the blood-stream, are all factors which need to be considered in framing the prognosis of the individual case. The “Metabolic group” is important, for in these cases there is mal- nutrition, the tissues are poisoned by the products of malassimilation and as Bruce has well said are starved at the same time.” 410 DISEASES OF THE CIRCULATORY APPARATUS Diabetics usually show evidences of marked arteriosclerosis, the dis- ease is rarely hypotensive, usually there is a normal or elevated blood pressure and often the pancreatic arteries are markedly changed. (See Diabetes mellitus.) Gout shows cardiovascular changes in almost 50 per cent of cases. 13. Hypertension There is a considerable period of hypertension which precedes pro- found changes of an organic nature in the arterial tree, which however, in the majority of cases is not recognized, because of a natural tolerance; and the almost immediate compensation. If hypertension persists unrelieved, and the factors which continue it remain uncontrolled, organic changes in vital organs are usually present, particularly in the heart, kidneys and within the splanchnic area, before the patient presents subjective manifestations. Hypertension long continued is the leading cause of arterial degen- eration. Prognosis of hypertension depends entirely upon the time of its rec- ognition, in no other way than by early recognition can its influence on heart, peripheral vessels, kidney and brain be controlled. ‘ When arteriosclerosis is established, hypertension is not a necessary feature; our statistics elsewhere given in this chapter prove that arterio- sclerosis may show normal, subnormal or high blood pressure. (See Blood Pressure Study.) “As a raised blood pressure is itself productive of degenerative changes in the vessels, we have good grounds for believing that if the rise be detected early, and counteracted by proper regimen and treatment, the vascular changes which it would otherwise produce might be prevented, and life very considerably prolonged. The earlier this is done the better, and I think it is only likely to be done by the sphygmo- manometer being used as frequently by the physician as the stethoscope or thermometer are at present.” (Lauder Brunton.) The prognosis is good when with hypertension there are no evidences of associated lesions. Hypertension in young subjects with uniformly thickened arteries, smooth and tense, who appear prematurely old, demands a guarded prognosis; it is usually progressive. Hypertension with marked renal symptoms, often without albumin, “non-albuminuric nephritis” is no longer uncomplicated, but in such sub- jects the degeneration of the arteries has commenced and the prognosis must be made accordingly; these are amenable to treatment. While the organic changes cannot be overcome or influenced unless specific, the prog- nosis so far as life is concerned is not necessarily bad. It may be safely concluded that uninfluenced hypertension in most cases is associated with changes in the renal vessels, the process is partly glomerular and partly includes the lesions of the granular kidney. ARTERIOSCLEROSIS 411 14. Kidney Invasion With advanced arteriosclerosis there are, as a rule, marked changes in the kidney substance; the evidences of nephritis are positive. Patholo- gists and clinicians in the study of arteriosclerosis have during the past sixty years made repeated attempts to satisfactorily explain the sequence of invasion of the heart, arteries and kidney and their reciprocal relations without reaching conclusions which may he accepted as final. The clini- cian knows that there are cases in which the process in the kidney seems to he primary and the arterial and heart changes secondary, on the other hand, there are cases in which the clinical history proves the presence of arteriosclerosis and heart compensation before there are positive evi- dences of interstitial, or mixed nephritis. Post mortem investigation shows the invasion of the kidney in the overwhelming number of cases of advanced arterial degeneration. The recent investigations of Fischer, J., who'examined 550 cases of marked hypertension in which the clinical and pathological evidences of nephritis were carefully noted are interesting: 62 per cent of these showed positive evidences of nephritis; 15 per cent were suspicious; 23 per cent gave normal urines. Excluding cases with blood pressure below 160 mm. Hg. in only 3.6 per cent was the urine normal. Autopsies of 42 cases showed positive nephritis; in 14 of these the urine during life showed no evidences of kidney disease. Krehl from his material reports in patients with a blood pressure of 200 mm. Hg. or higher 87.4 per cent with nephritis—of these he autopsied 43 cases, of which 42 gave positive evidences of nephritis. Adami says “arteriorenal problems are among the most complicated and obscure in the whole of pathology.” In presenting this subject we feel the safest conclusion to reach is that arteriosclerosis and hypertension may occur without the symptoms of renal invasion, that with high blood pressure, tense thick arteries, hypertrophy of the left ventricle, there is nephritis in almost all cases. The absence of albumin and casts from the urine during long periods with such positive objective features does not argue against the presence of nephritis and the prognosis should be accordingly made. With arteriosclerosis in any of its stages the prognosis is unfavorable in proportion to the extent of kidney involvement. 15. Coronary, Myocardial, Endocardial and other Heart Lesions In all cases of arteriosclerosis in which there have been evidences of coronary disease the prognosis for Restitutio ad integrum is had, though life may he prolonged, and the patient may die of intercurrent disease years after the initial symptom of angina pectoris or anginoid disease. The coronary trunks may he atheromatous, tracing them into their 412 DISEASES OF THE CIRCULATORY APPARATUS intramuscular network, the finer branches may be free from any trace of disease and thus sufficient blood is sent to the myocardium to maintain the left ventricle. Such cases, unless overtaxed, may live many years with but few symptoms. Patients may have a single severe attack of angina pectoris or suffer repeated “small attacks,” symptoms may he present which prove deep involvement of the coronaries and yet the heart pang and other reminders of coronorary sclerosis may he absent for months or years at a time; and it is not at all unusual, particularly in thoroughly treated specific cases, or in cases which have developed mur- murs and slight dilatation to find the symptom complex permanently re- lieved. We refer the reader for the full consideration of the prognosis of coronary disease to the chapter on Angina Pectoris. Myocardial degeneration associated with arteriosclerosis is always ominous; this is especially true of the senile heart, when overtaxed. The prevention of mechanical strain often makes it possible for these patients to live comfortably during many years; life may be sacrificed by a sin- gle indiscretion. Arteriosclerosis of specific origin leading to myocarditis may yield to treatment. With long continued hypertension and an overworked heart, there is great danger of sudden revolt of the heart muscle with disastrous results. With necrotic processes in the myocardium resulting from coronary occlu- sion, the prognosis is bad. Coronary disease is the most frequent cause of disorganizing changes in the myocardium. The closure of one branch of the coronary does not always lead to death. Such advanced disease is always serious. The condition of the heart muscle is the most important factor in the prognosis of arteriosclerosis, in the myocardium rests the key of the heart and upon it we must depend. In our experience myocardium degeneration accompanied one-sixth of all cases of arteriosclerosis at the time of its detection. The prognosis of myocardial degeneration is fully considered in another chapter {Myo- carditis) . Advanced arteriosclerosis is associated with compensatory hypertrophy of the left ventricle. So long as these changes'are sufficient, m the ab- sence of added complications, the prognosis for life is good. Such subjects may live for years without inconvenience unless they overtax their cardio- vascular system. We cannot subscribe to the dictum which holds that such hearts prove as resistant as normal hearts. They are not, they do not brook insult, they revolt on slight cause. With advanced coronary sclerosis there is reduced heart strength and dilatation may lead to sudden death. Long continued hypertension with hypertrophy of the heart is asso- ciated with nephritis in most instances and offers a bad prognosis. ARTERIOSCLEROSIS 413 The condition of the peripheral arteries and the kidney are important factors to be considered in connection with the heart anomalies of arterio- sclerosis. Marked accentuation of the aortic second sound is proof of increased peripheral resistance and with aortic obstruction (vascular), showing itself in a well marked basic systolic murmur, we may be sure of advanced sclerosis, usually including the ascending aorta; conditions which are permanent but with favorable environment and right living the patient may live during many years. Naturally aneurismal dilatation of the aorta alters the prognosis. With marked widening of the ascending aorta and a corroborative x-ray picture, we have often found an area of tympany and exaggerated breathing to the right of the sternal edge in the aortic space and around it and the aortic impulse increased; this is of serious moment. Usually these cases are associated with coronary disease. (See Aneurism of the larger arteries.) The frequency of the pulse with persistent high blood pressure is of prognostic significance. Rapid pulse, whether intermittent or arhythmic, with myocardial or other heart lesions, with or without high blood pres- sure tires the heart and reduces the chances of prolonging life. Inter- mission, arhythmia and irregularity, may persist during years without shortening the life of the patient. Such anomalies are well borne in older subjects; in the young in whom they arise suddenly, life is at once threat- ened. The prognosis is always better in those cases in which the heart has gradually fallen into the habit of being erratic and the muscle has learned to accommodate itself. None of the hearts with the above men- tioned anomalies are dependable, though they may serve when undisturbed by added complications during surprisingly long periods. Cardiac asthenia and pulmonary edema due to cardiovascular degen- eration are usually terminal conditions and of grave import. Even these threatening complications may with proper care be followed by long periods of comparative comfort. The endocardial changes of arteriosclerosis are degenerative and not inflammatory. The greater the invasion of the aortic cusps and the adja- cent endocardium the worse is the prognosis. Simple aortic obstruction without incompetence due to roughness of the valves and the ascending aorta may persist during years without causing damage or symptoms when uncomplicated. When the aortic cusps are so malformed as to become insufficient, a different picture is presented; the heart has an added burden, its further hypertrophy follows, the pulse amplitude shows the enormous load which such hearts are carrying and degenerative myocarditis, apoplexy, uremia or other complications must be expected. Such hearts are ready to sur- render on slight cause. 414 DISEASES OF THE CIRCULATORY APPARATUS Increase of 'physical signs particularly in arteriosclerotics with dia- betes and gout, fresh murmurs (aortic) with evidence of insufficiency is always ominous and shortens life. With aortitis and diabetes the prog- nosis is bad; there is always danger of corna. Gangrene when an evidence of endarteritis obliterans is not a limited process, there are often associated metabolic faults (diabetes, gout), the arterial tree is extensively involved and prognosis as a rule is bad. Life has been prolonged in some cases by surgical interference but the exten- sion is not usually long. 16. Vascular Crisis (Spasm) et Vascular crisis” is a term which was introduced very largely as the result of the investigations of Pel to characterize recurring, suddenly arising symptoms of a painful character in the domain of changed arteries. Vascular crises are associated with diseased arteries in which the definite symptom-complex is due to vascular contraction, temporary nar- rowing of the artery; occasionally extreme dilatation or vasodilator paralysis may predominate. Vascular spasm or crisis explain the sensory symptoms included in anginous attacks, intermittent claudication, some cases of Adams-Stokes phenomenon, evanescent muscular pains and cramps in the subjects of arteriosclerosis, abdominal angina, or the Dyspragia intestinalis inter- mittens of Ortner; the crisis of tabes in cases associated with arterial degeneration, a condition which is often present early in young tabetics and many cerebral and spinal symptoms of short duration. Vascular crises are provoked by factors which throw an extra tax upon the heart and the organ invaded. This is a fact of enormous impor- tance to be considered in prognosis and treatment. Vascular spasm is evidence of developed arteriosclerosis, and is not present, in our experience during the early stage of hypertension; it always adds to existing dangers; more when vital organs (heart and brain) are involved. The anginous attacks we have considered elsewhere; most of these are due to coronary spasm. Intermittent Claudication (Dysbasia intermittens angiosclerotica) Vascular spasm of the lower extremities usually provoked by walk- ing or movement of the limbs to which Erb called attention, and which ARTERIOSCLEROSIS 415 is increasing with the increase of arterial degeneration may recur during long periods, may be associated with erythromelalgia, Raynaud’s Disease, or may in cases of advanced obliterating endarteritis precede gangrene during long or short periods. Erythromelalgia as we have demonstrated (Eisner) is usually due to arteriosclerosis. Its symptomatology includes the ured neuralgia” of Weir Mitchell, but contrary to his original con- tention it may ultimately lead to sufficient obstruction of the circulation to cause gangrene or limited necrobiosis. (See Erythromelalgia.) Acroparesthesia and many of the other sensory disturbances of the extremities are due to arteriosclerosis and associated vascular spasm. (See Acroparesthesia.) Threatening brain symptoms—vertigo, transitory paralyses, aphasia, also paraplegia and temporary abeyance of function in other organs are often warnings of approaching danger due to vascular spasm. Transitory blindness in one eye in the subject of arteriosclerosis may be dependent upon vascular spasm. In this connection the experience of Wegenmann is corroborative. Wegenmann’s patient was a man aged sixty-three years who had arteriosclerosis and who had transitory periods of blindness in his right eye. On one occasion Wegenmann was present when the patient became suddenly blind. An ophthalmoscopic examina- tion was made; the arteries during the period of blindness were found empty. They were converted into threadlike shining strands, yellow in color. ISTormal pulsation had ceased. The veins resembled threadlike but red strings. Pressure on the eye did not cause pulsation. This con- dition continued during ten minutes, the observer found as the spasm was relieved, the arteries filled and the veins dilated, with a return of pulsation and of sight. It is a question whether the pains of lead colic, in which we know there is arterial change (hypertension) are not due to vascular spasm. The prognosis of arterial spasm is not encouraging—an expression of fully developed arteriosclerosis—it is a symptom of a far-reaching process. When vascular spasm causes the Adams-StoJces phenomenon because of arterial change in the vascular supply of the intraventricular septum, a condition which is not unusual, the prognosis of non-specific cases is absolutely bad. With specif c arteritis it may cause sudden death. Vascular spasm of the cerebral and spinal vessels has in some of our cases persisted during a number of years; finally these patients invariably succumbed to the underlying conditions. Unless vascular spasm is dependent upon a removable cause such as syphilitic end-arteritis there may be improvement and temporary relief but never cure. 416 DISEASES OF THE CIRCULATORY APPARATUS The influence of cerebral, spinal and peripheral changes of the ner- vous system and psychoses are separately considered. Neurasthenic conditions are common and rebellious. (See Neurasthenia.) 17. Cerebral, Spinal and Peripheral Changes 18. The Blood Pressure Study of Arteriosclerosis {after the stage of hypertension) The revelations of the sphygmomanometer (blood-pressure study) are too often misinterpreted to the disadvantage of the patient; this is par- ticularly true of blood pressure in connection with arteriosclerosis. The suggestion to the patient that he “has blood pressure” is often depressing and starts an autosuggestion which may prove injurious. With increased blood pressure sufficient to “meet physiological de- mands” the various tissues of the body are given a sufficient blood supply. Occasionally a high blood pressure causes weakness of the diseased walls of the vessel and rupture results, “a high blood pressure with this excep- tion is not to be regarded as something evil, but as an attempt on the part of the body to keep our various organs working at their physiological optimum” (Fisher). Elevated or changed blood pressure is therefore often a conservative and compensatory process to be left undisturbed; at times encouraged; it is a balancing and protective measure. Blood pressure study alone offers much less information of value in framing prognosis than is generally supposed. Arteriosclerosis may be far advanced without marked change in the systolic pressure, it may remain normal; in some cases there is, after the initial period of hypertension persistence of the same pressure, while in another class of cases there may even be hypotension. In the cases of advanced arteriosclerosis mentioned in the beginning of this chapter in connection with the study of 5,708 cases of internal disease I found persisting hypertension (above 180 mm. Hg.) in 181 cases or 3.17 per cent and striking hypotension in 21 cases. In 623 arteriosclerotics the per cent of hypertension cases was 29. Sawada found of 206 cases of arteriosclerosis, 122 not complicated with marked lesions, 12.3 per cent with high blood pressure. In 75 with heart com- plication and albuminuria 30.6 per cent showed hypertension. Janeway found 11.9 per cent of all of his cases of internal disease (7,872 patients) with systolic blood pressure above 165 mm. Hg. and 458 of these had permanent hypertension. Of 870 patients with hypertension at some time 62.4 per cent were men and 37.6 per cent were women. Of the 458 cases of persisting hypertension 67 per cent were men and 33 per cent women. Janeway found at the end of the nine year period the number of men dead were 6.2 per cent more than living; women living ARTERIOSCLEROSIS 417 were 35 per cent more than dead. Thus 20.6 per cent more men died than women. This experience is confirmed by all observers—women bear arteriosclerosis better than men, unquestionably the prognosis would be the same if both sexes were exposed to the same conditions. Arteriosclerotics bear operations badly, this is particularly true of men with high blood pressure who subject themselves to prostatectomy. A number of these develop uremic symptoms with suppression of urine within 24 to 48 hours of the operation fall into coma and die. It will be seen from the statistics of Janeway and those which I offer, that arteriosclerosis is not necessarily a hypertensive disease. My figures differ because Janeway included all cases above 165 and I only those above 180 mm. Ilg. Blood pressure study calls attention to possibilities and should be so interpreted. Young subjects who appear prematurely old with persistingly high blood pressure offer unfavorable prognoses. High pressure with renal changes, also cases of “non-albuminuric nephritis” and dilated heart or associated coronary disease offer unfavor- able prognoses. Pulse Pressure The study of the minimum or diastolic pressure which gives also the pulse pressure (difference between the systolic and diastolic pressure) is more important for prognostic purposes than the systolic pressure alone. It makes clear “the burden” which the heart is bearing. “Pulse pressure measures the energy of the heart in systole in excess of the diastolic pressure” (Stone). A sustained diastolic pressure of from 100-110 signifies hyperten- sion; it measures peripheral resistance and is therefore a “better index of hypertension than the systolic pressure” and “is less influenced by physiologic factors than the systolic pressure” (Stone). In cases in which the blood pressure is high, but the normal ratio between the maximum and minimum (systolic and diastolic) pressure is not markedly altered, we are justified in offering a favorable prognosis for the chances are against grave organic change in favor of a stage of hypercontractility of the walls of the vessels, which rational treatment may relieve. Sudden reduction of high pressure may lead to serious conditions, including anuria, coma, myocardial ■weakness and death. Low systolic blood pressure after a period of hypertension with neph- ritis usually leads to sudden death because of “cardiac defect” (Allbutt). The greatest differences in systolic and diastolic pressure, hence the highest pulse amplitude or pulse pressure, are found with advanced aortic disease (insufficiency), chronic interstitial nephritis with double 418 DISEASES OF THE CIRCULATORY APPARATUS aortic murmurs and marked cardiac hypertrophy. All offer grave prognoses. Invasion of the splanchnics (the mesenteric arteries) is associated with high pressure during long periods and with persisting toxemia usually due to intestinal disturbance throws added work on the cardio- vascular system, influencing prognosis unfavorably unless promptly relieved. The great difficulty which we face in the problem of arteriosclerosis and blood pressure study is that we do not know the strength of the arterial wall; with normal or increased pressure miliary aneurisms of the cerebral arteries or ulcerating defects of the larger vessels may lead to hemorrhage {rupture) ; dilatations and various other irreparable complications. With changed blood pressure, cerebral warnings, including vertigo, spasm or convulsions, lapses of memory, active or passive cerebral hyper- emia, associated edema, sudden dyspnea, increase of kidney symptoms including uremic poisoning or indiscretions may be followed by a decided break leading to death. 19. Thrombosis Arteriosclerosis is a frequent cause of thrombosis; the complication is always serious. With coronary disease suddenly developing thrombosis is a frequent cause of death. With sclerosis of the pulmonary artery, multiple organized and firmly attached thrombi are not infrequently found post mortem which must have antedated death during comparatively long periods; the patients dying of other causes. Arteriosclerosis of the pulmonary artery may exist without change in the arteries of the body; it is often found with mitral lesions and emphysema; in such cases there is increased blood pressure in the pulmonary circuit and hypertrophy of the right ventricle. Thrombi are more frequent in the smaller arteries and consecutive changes due to occlusion must be expected. Thrombi in the aorta are frequent and may start emboli to the brain or other vital organs. Hemorrhagic infarct secondary to aortitis with thrombosis in the brain, spleen, kidney or liver may lead to death. The thrombus of aortic aneurism is not so firmly attached as is the organized plug in the pulmonary artery. 20. Ocular Changes Advanced arteriosclerosis particularly when associated with inter- stitial nephritis shows evidences of change in the retinal vessels. The presence of retinitis albuminuria with arteriosclerosis never justifies anv other than an unfavorable prognosis. Such patients stand on the edge ARTERIOSCLEROSIS 419 of a precipice and may fall at any moment. They rarely live two years after the onset of the retinitis. Cerebral apoplexy, uremia, pneumonia and sudden myocardial failure are the causes of death. Large and suddenly arising retinal hemorrhages are evidences of the terminal stage or far advanced disease. Advanced arteriosclerosis shows involvement of the retinal vessels in the majority of cases. The ophthalmoscope therefore is a valuable prog- nostic aid. 21. X-ray The revelations of the Rontgen picture in individual cases will prove of value in prognosis. This is particularly true of changes in the aorta (aneurism, etc.), and in the differentiation of specific and non-specific arteritis. Our views concerning the prognosis of arteriosclerosis have been ma- terially changed during the past fifty years. This fact is proved by the following quotations from Bamberger, who represented the climax of medicine in Germany sixty years ago, and from Romberg, who stands today as the exponent of all that is advanced in cardiovascular pathology and diagnosis. Bamberger said, “Atheromatous processes cannot be cured, hence they cannot be treated.” Romberg holds: “While we are not able to alter the anatomic changes in the blood vessels, the seat of arteriosclerosis, we can nevertheless improve the functions of the organs invaded and exert material influence on the advance of the process.” The prognosis in every case of arteriosclerosis must be based not only on the subjective and objective manifestations which are evident, but a thorough inquiry into the patient’s entire history, the influence of his occupation and his habits, the diseases which he has had, his “constitu- tional strength and physical training and disposition in earlier years, and more remote than these, his inheritance.” (Bruce.) In no other process does inheritance, the character of the individual, his disposition, temperament and circumstances play such an important role. In arteriosclerosis there is often a single and .preventable cause, not an extension of the degeneration which produces the death of the patient. Much naturally depends on the location of lesions; limited arterio- sclerosis—a small plaque at the mouth of a coronary vessel—a small miliary aneurism of a cerebral vessel, circumscribed sclerosis with local- ized myocardial degeneration and rupture, may cause sudden death, while with disseminated change in the arterial tree, the patient may live for years in comfort, oblivious of his lesions. “The first requisite for longevity must clearly be the inherent or inborn quality of endurance; of steady, persistent nutritive force, which 420 DISEASES OF THE CIRCULATORY APPARATUS includes reparatory force and resistance of disturbing effects; and a good proportion or balance between the several organs. The second requisite is freedom from exposure to the various casualties, indiscretions, and other causes of disease to which illness and early death are so much due.” (Humphry.) References Adami.

Aneurism Aneurism may be defined as a chronic dilatation of a blood vessel with productive (connective tissue) change of its wall, the cavity always communicating with the lumen of the artery. For our purpose we con- sider only the circumscribed and diffuse dilatations. The most common form of the former is the saccular aneurism, of the diffuse—the spindle shaped. Miliary aneurisms will be considered in connection with cerebral apoplexy. ANEURISM 421 Dissecting aneurisms are due to incomplete rents in the walls of a blood vessel; the layers of the vessel are undermined by the blood and consecutive deposit. This variety is of interest pathologically only. The leading pathogenic factors to be considered in the formation of aneurismal dilatations are diseased blood vessels, arteritis—usually spe- cific arteriosclerosis; besides syphilis, typhoid fever, diphtheria, endo- carditis (malignant) and other infections, traumatism and increased blood pressure. In our hospital and consultation practice we have found at least 90 per cent of all cases due to syphilis. Malmsten found 80 per cent syphilitic. Recent experiences give positive Wassermann reactions with almost all aneurisms, particularly the aortic dilatations. Unquestionably syphilis leads to arteritis and arteriosclerosis in young subjects and thus lays the foundation for dilatation on slight cause. The prognosis of all aneurismal dilatation so far as life is concerned depends upon its location, its size, the condition of the arterial wall, the blood pressure, the strength and condition of the myocardium and valves, the extent of degeneration of the arterial tree, the relation of the growth to the surrounding organs, the amount of pressure it exerts, the extent of paralysis (particularly of the vagus'), the amount of pressure upon nerve trunks and bone tissue, the protecting influence of coagulation and throm- bosis within the sac, the results and amount of obstruction to the blood stream which folloivs, as well as many other factors, including lesions in vital organs, brain, liver and kidney, which are likely to be associated with cardiovascular disease. More than two-thirds of all aneurisms are found in men between the 38th and 60th year. Cominotti found aneu- rism five times as often in men than in women. He found 24 between the ages of 24 and 40 years, 29 between 40 and 50, 18 between 50 and 60. Marchand in 28 autopsies of aneurisms found 20 men and 8 women, 2 were between 30 and 39 years of age, 6 between 40 and 49 years, 10 between 50 and 59 years, 4 between 60 and 69 years and 6 between 10 and 90 years. The greater frequency of aneurism in England and in the United States than on the Continent of Europe is established by statistical study. The negro is more disposed to aneurism than is the white man. Myers found in 320 deaths of soldiers in the English Army resulting from cardiovascular lesions 138 aneurisms; of 1,346 invalided soldiers 35 had aneurisms. Crisp reports 551 aneurisms, spindel and saculated, located as follows: Aorta (thoracic) 175 Popliteal artery 137 Femoral artery 66 Abdominal aorta 59 Carotid artery 25 422 DISEASES OF THE CIRCULATORY APPARATUS Subclavian artery 23 Innominate artery 20 Axillary artery 18 Iliac artery 11 Arteries of the internal organs 8 Cerebral arteries 7 Pulmonary artery 2 Cominotti found in 181 aneurisms, 37 of the ascending aorta, 49 of the arch of the aorta, 29 of the descending aorta and 16 of the abdom- inal aorta. Nature may either protect the arterial wall or occasionally, by its reparative process, cause obliteration of the sac and relative cure. Thus dense and organized coagula in moderate sized dilatations, without marked interference with heart or distant organs, may exist during years,, and death may be due to other causes. By the reinforcing of the aneurism with fibrous tissue the growth may become stationary. The tendency of all aneurismal dilatations is towards progression, with compression and adhesion to the surrounding organs. Rupture of the wall is the most frequent cause of sudden death. Thrombosis may prove sufficiently extensive to close the aneurismal sac and present a smooth surface to the blood stream. Moderate dilatations may be smoothed aud protected during long periods by dense and firmly organized thrombi. A small artery with aneurismal dilatation may be side-tracked by Nature’s processes without interfering with the heart or the general health. (Collateral Circulation.) (Jores.) Infectious processes, tuberculosis particularly, may cause ulcerative changes in the arterial wall leading to aneurismal dilatation. This method of producing aneurisms holds only for the smaller arteries. The mycotic-embolic aneurisms which arise during the course of malignant or infectious endocarditis are usually multiple and follow ulcerative changes in the walls of arteries. This is a part of a process which is always fatal. Embolic detachments from aneurismal walls are not frequent; occa- sionally they may lead to sudden death, hemorrhagic infarcts in the lung, spleen, kidney, brain or other organs; rarely to gangrene. X-ray examination of all aneurisms gives positive data which make clear the location, the size, the relations to surrounding organs, as well as other important facts ivhich bear upon the diagnosis and prognosis in individual cases. The further complications which influence prognosis are considered in connection with the separate aneurisms. ANEURISM 423 1. Aneurism of the Ascending Portion of the Arch of the Aorta Aneurism of the ascending portion of the arch of the aorta is a sequel of syphilitic aortitis, and is always fatal. When the x-ray shows the presence of the dilatation, the radial pulses are unequal, there are other evidences of pressure with secondary heart changes, death may be expected at any time. With aneurism of the aorta in any of its parts and associated coronary disease the patient’s life is in constant jeopardy; such a patient is “always dying.” The thickness of the aneurismal wall and the size of the aperture communicating with the aorta influence the force of the pulsation (“ex- pansile thrill”). The growth increases by expansion. Thin aneurismal dilatations just above the aortic valve or of one of the cusps of the valve may rupture into the pericardium without having caused previous symptoms (Aneurism of a Sinus of Valsalva). With these cases coronary invasion and aortic insufficiency is not uncommon, the latter at times leads to hypertrophy of the left ventricle. Dyspnea and cyanosis are not long endured, they indicate a tired heart and pressure with pulmonary obstruction. Edema of the upper extremities—one or both—when once established is likely to persist until death. Pulmonary ede?na on slight cause, particularly during and after coitus, is often a terminal symptom. All pressure symptoms, once established are likely to continue. The extent of compression showing itself in symptoms, is a valuable guide for prognosis and justifies conclusions which the experienced can usually reach concerning the average time which the patient may live—- barring sudden rupture which is always to he expected with all aortic aneurisms. 2. Aneurism of the Transverse Portion of the Arch of the Aorta The anatomic location of the arch leads to symptoms of compression often before dilatation is far advanced. Aneurism of the arch of the aorta is likely to be associated with some change of the ascending por- tion also, as the process advances. The displacement of the heart, usually to the left, may exist without marked hypertrophy of the ventricle. When the aortic valve is insuffi- cient, as often happens, the hypertrophy is enormous. 424 DISEASES OF THE CIRCULATORY APPARATUS Marked systolic bruit and tracheal tugging are evidences of advanced aneurism. Paralysis of the left recurrent laryngeal nerve is proof of advanced aneurismal dilatation in the presence of other physical signs and persists unrelieved to the end. If the innominate is involved, or if there is suffi- cient pressure, the right recurrent may also suffer; under these condi- tions the end will not be long postponed in the average case. The papillary changes are due to involvement of the sympathetic system and are proof of advanced disease. 3. Aneurism of the Descending Portion of the Arch of the Aorta Aneurism of the descending ‘portion of the aortic arch may exist during a considerable period without causing symptoms. The recogni- tion is often postponed because of the failure to interpret the significance of the multiple symptoms of many intrathoracic lesions which are included when subjective complaints are made, and the further failure to take advantage of Rontgen examination. The aneurism may cause intercostal pain during a long period when finally positive evidences of compression in erosion of the dorsal vertebrae (usually third to the sixth) is added; there may be evidences of bronchial and lung pressure, or the mass may present externally in the scapular region. Rupture into the pleura, bronchus or lung is the fate of a large number of aneurisms of the descending portion of the arch. Early recognition of aortic aneurism wherever located which is pos- sible by x-ray examination with immediate rational treatment, including the indicated rest, offers the o?ily encouragement for the prolongation of life. 4. Aneurism of the Descending Thoracic and Abdominal Aorta Aneurism of the descending aorta below the arch, may cause but few symptoms until advanced, when pains—intercostal and lumbar—with epigastric or thoracic pulsation persist. The stomach and liver may be displaced. With abdominal aneurism the systolic bruit can be distinctly beard posteriorly, a symptom of great diagnostic and prognostic value in doubtful cases. Erosion of bone (vertebrae) and other symptoms of compression, edema of the extremities are present in advanced cases. ANEURISM 425 3. Aneurisms of the Celiac Axis Aneurisms of the celiac axis or its branches may prove of anatomic interest, they may not be diagnosticated intra vitanu as there may be no symptoms. In one case I found the symptoms of hemorrhagic pancreatitis arise suddenly in a man age 65. The autopsy showed rupture of the disorganized axis into the pancreas. The prognosis of splenic, hepatic and renal aneurism is equally bad. There may be aneurismal dilatation of one of the mesenteric arteries, usually the superior, which causes vague symptoms, may lead to death from rupture or it may be accidentally discovered at autopsy. 6. Aneurism of the Coronary Artery Aneurism of the coronary arteries is exceedingly rare, leads to death by rupture into the pericardium or heart muscle. (Wardrop.) Griffith has collected these cases in a splendid article. 7. Aneurism of the Pulmonary Artery Aneurism of the pulmonary artery or its branches is also rare. Our experience includes one case in which we failed to make the correct diag- nosis (though aneurism was strongly suspected) because the aneurismal dilatation rested on the heart wall anteriorly and consequently did not show in the skiagram. Death resulted from rupture into the pericardium. 8. Aneurism of the Subclavian Artery With subclavian aneurism we have seen long periods during which there was no advance of growth or symptoms. The growth of an aneurism is rarely continuous; there seem to be sudden exacerbation in many. The hope of prolonging life rests in the strengthening of the arterial wall and the organization of coagula (thrombosis) by Nature’s processes. Landraf reports a case of aortic aneurism in which paralysis of the recurrent laryngeal disappeared. This is exceedingly rare. The dissecting aneurism usually leads to early perforation; other aneurismal dilatations perforate in the later stages, after long periods of compression and expansion. Fifteen to twenty per cent of all aneu- risms perforate. The perforation usually leads to prompt death; in ex- ceptional cases a rent may be closed by a thrombus or perforation may 426 DISEASES OF THE CIRCULATORY APPARATUS take place into organized tissue, into a vein or into the substance of a solid organ when death may be postponed for a short time. Location of an aneurism does not change the prognosis so far as its influence on life is concerned; with all, the outlook is equally grave, all stand on the edge of a precipice; when the fall is to follow no clinician can prophesy. We may safely conclude that aneurism is rarely cured by any method of treatment. Nature's methods of spontaneous relief we have already considered. Death is the fate of most patients with aneurism within from six to eighteen months after the diagnosis has been fully established. There are exceptions to this rule; cases are recorded by all experienced clini- cians which lived during years, but these are notable exceptions. References Cominotti. Wien. med.

Diseases of the Pericardium 1. Acute Pericarditis" Acute pericarditis is a secondary inflammation of the pericardial sac, rarely primary, associated in the order of frequency with rheumatism, tuberculosis, pneumonia, pleurisy, scarlet fever and typhoid fever. It may also occur with other exanthemata as measles, smallpox, etc., and is not an infrequent accompaniment of septic and pyemic infection. It is in many cases coincident with valvular lesions—endocarditis and myocarditis. Echinococcus disease and actinomycosis may provoke it; it is occa- sionally found with gonorrhea, may follow extension of cancer and sar- coma from the surrounding organs, may be secondary to perforation of the esophagus or of the pleura with empyema; abscess of the liver and subphrenic abscess may perforate into the pericardium as may pyopneumo- * The reader is also referred to chapters on the separate infections where the prognostic significance of pericarditis is considered among the complications. DISEASES OF THE PERICARDIUM 427 thorax; gastric and intestinal ulcers with adhesions and inflammation may lead to pericarditis. Chronic interstitial nephritis is often associated with pericarditis. Romberg quotes Frerichs and Rosenstein as having found the sac in- flamed in 13 of 292 and 8 of 114 cases respectively—5.1 per cent. Pericarditis may also complicate scorbutus, other purpuric conditions, leukemia and pernicious anemia. Penetrating wounds of the thorax, gunshot wounds, erysipelatous in- flammation of the thoracic walls or phlegmonous infiltration with suppura- tion when they involve the heart sac usually cause purulent pericarditis as do also the malignant perforating diseases already mentioned; all offer unfavorable prognoses. The so-called idiopathic pericarditis of children is almost always of tuberculous origin in the absence of positive proof of other causes. (Rheu- matism, scarlet fever, etc.). When pericarditis accompanies puerperal sepsis it is likely to be purulent and fatal. Naturally pericarditis is found in those of all ages since it is an accom- paniment of so many infections, as well as other constitutional anomalies and accidents. The pericarditis of rheumatism is present in from 5 to 6 per cent of fully developed cases in adults and from 10 to 20 per cent in children. In the majority of these endocarditis with some change in the myocardium is present. There are occasional severe cases in which the heart sac is in- volved before there are evidences of arthritis. A large number of fatal cases of chorea with and without joint symptoms and tonsillitides are at times complicated by pericarditis and are of rheumatic origin. The prognostic significance of pericarditis depends almost entirely on the nature and gravity of the primary disorder. The reader will find the subject separately and fully treated in connection with the consideration of the complications of rheumatism, tuberculosis, pneumonia, scarlet fever, pleurisy, typhoid fever, erysipelas, chorea, tonsillitis and all other infec- tions, beside septic and pyemic conditions, to which he is referred. When pericarditis does not advance beyond the first or dry stage (peri- carditis sicca) it has, per se, very little influence on the course of primary disease. Romberg, however, reports 85 cases of pericarditis with 24 deaths, a high mortality. At Johns Hopkins Hospital Hoffman’s statistics show among 1,770 medical cases admitted (1902-1911) 1,317 (1,044 males, 273 females) cases of circulatory diseases, among these were 22 diseases of the pericardium (14 males with 5 deaths—35.7 per cent) (8 females—2 deaths—25 per cent), of these 11 males had pericarditis with 3 deaths, 27.3 per cent, and 6 females with 1 death, 16.7 per cent. The effusion may be fibrinous, serofibrinous, purulent or blood stained. 428 DISEASES OF THE CIRCULATORY APPARATUS The less severe types are fibrinous and serofibrinous with rheumatism; purulent effusion is associated with septic and pyemic infections and is always serious, usually fatal. Those purulent effusions are most serious which are associated with puerperal sepsis, pyemia, malignant endocarditis and in cases in which there are bands of adhesion which bind the heart anteriorly when the pus is held in the dependent portion of the pericardium beyond the easy reach of the operator. The blood stained eff usion is usually found with tuberculosis, cancer, sarcoma, purpura or scorbutus. It is always an indication of serious con- stitutional disturbance and is likely to end in death. The serofibrinous effusions with the infections (rheumatism, scarlet fever, tonsillitis) are, unless the primary disease leads to death, absorbed in the course of a limited period with resulting temporary or permanent adhesions. The extent of the adhesions and their permanency are important fac- tors in limiting the action of the heart and are considered in connection with adherent pericardium. Moderate adhesions with partial obliteration of the heart sac do not often lead to permanent subjective symptoms after recovery. Calcareous Pericarditis.—In a few cases there may be calcareous deposits in the pericardium, the prognostic significance of these depends entirely upon the extent of the degeneration, the condition of the heart muscle and the nature of the accompanying chronic changes in other organs. Purulent pericarditis may be followed by calcareous deposit; this is exceedingly rare as most purulent cases die. Acute Myocarditis.—Acute myocarditis may be complicated by peri- carditis. In these cases the spread is from the myocardium and invades the pericardium in the neighborhood of the primary muscle change. But few cases of pericarditis are without more or less myocarditis. The extent of the latter is of paramount importance. Myocardial inflammation associated with pericarditis when far reach- ing or in a previously weakened or diseased heart may lead to cardiac insufficiency. Dilatation of the heart is not infrequent; usually the right heart is involved, with relative muscular weakness. If in such cases the patient lives and there are adhesions or lowered vitality, myocardial de- generation may follow and there may be cellular infiltration, fibroid change or atrophy. The heart and surrounding organs are tolerant of pericardial effusion during long periods. The sac may contain a large quantity of fluid with- out threatening life. Rapidly increasing exudate is more threatening to life than is the gradual accumulation. X-Ray Examination.—The assistance received from the Rontgen DISEASES OF THE PERICARDIUM 429 picture is not always to be relied upon in the presence of moderate effu- sion ; it will nevertheless prove a valuable aid in prognosis in many cases. Pericardial adhesions are often beautifully clear in the picture, more par- ticularly the extrapericardial hands. Displacement of the lung with tracheal pressure and involvement of the mediastinum, often with paralysis of the recurrent laryngeal nerve, may prove serious and unless relieved becomes life-threatening. Pulmonary edema with insufficiency of the right heart and dilatation of the ventricle may lead to sudden death. When pressure leads to dropsy and there is associated myocarditis the prognosis is grave. Thrombosis, either pulmonary or in the left innominate, increases ob- struction and is usually fatal. Pericarditis with chronic Bright’s disease is a terminal complication (See Nephritis). Sy?nptoms referable to the nervous system as delirium, coma, convul- sions, marked apathy and prolonged insomnia are evidences of the graver infections. With osteomyelitis, pericarditis adds a large element of danger to an infection already malignant. The behavior of the temperature offers but little to guide in offering a forecast. Pericarditis may develop insidiously without marked rise of temperature or other symptoms; the temperature may on the other hand remain unchanged by pericardial involvement in the presence of the primary disease. With pyemic and septic pericarditis the advent may be heralded by a distinct chill and rise of temperature above the previous level. These chills as in all similar infections are likely to recur, to be followed by fever and excessive sweating, with or without added pericarditis. Physical signs, i. e., friction sounds, are more dependable than any one other symptom to mark the beginning of the pericardial complication. If large effusion continues unrelieved during long periods and in cases where after its removal it promptly reforms, the prognosis is bad. These patients fall into a chronic state of invalidism which ends in asthenia with symptoms of compression. Among the unfavorable symptoms are unusually large effusions, marked dyspnea, advanced myocardial weakness, small, feeble, erratic and rapid pulse, the pulsus parodoxus in cases with thickened pericardium, cyanosis, delirium, coma, albuminuria with scanty urine and evidences of septic nephritis, marked tremor, and in children persistent vomiting, hiccough and increasing anemia. The prognosis during early life is under all conditions less favorable than in the adult. In children under ten years of age most pericardial effusions are purulent. Mediastinal lesions with pericardial inflammation or extension of mediastinitis to the pericardium often lead to dense and 430 DISEASES OF THE CIRCULATORY APPARATUS troublesome adhesions and heart weakness. These cases are likely to be subacute or chronic; reference is again made to them under “adherent ;pericardium,.” The duration of the disease depends upon the nature of the primary infection. The average case runs its course in from 14 to 21 days, but there are so many factors to influence the complication that it is never safe to commit oneself to a time limit. In but few cases does pericarditis per se lead to death. Evidences of heart weakness, including dyspnea on exertion, fatigue, syncope, and erratic heart action may continue long after the beginning of convalescence. Valvular Lesions and Pericarditis.—Gerhardt, C., calls attention to the frequency of pericarditis with valvular disease of rheumatic origin. The evidences of endocarditis may remain unrecognized until the peri- cardial effusion has been absorbed. He further accents the fact already mentioned that in the presence of chronic valvular lesions pericarditis may arise without known cause insidiously, and may lead to permanent myo- cardial damage. The frequent association of pericarditis and aortic val- vular disease was shown in an analysis of 197 rheumatic cases with pericarditis in 17, and in 13 of these, the aortic valve was involved, once alone, in nine cases the aortic lesion was not prominent, in only four cases was the disease limited to the mitral valve alone. The relatively infre- quent involvement of the aortic valve with rheumatism would, from Ger- hardt’s anatomic experiences prove the greater tendency to complicating pericarditis with lesions of the aortic valve, the nearness of the overlying pericardium may be an important factor. Pericarditis complicating old heart lesions, chronic valvular defects or myocarditis is always serious. In these cases it matters- little what the primary cause of the pericarditis may be, the heart revolts, becomes rapid, dilates, there is pulmonary engorgement, general venous stasis, cyanosed kidney and unless treatment proves promptly efficacious, death results. In many cases the sequelae of pericarditis interfere with comfort and the prolongation of life. There may be adhesions, distortion and consecu- tive interference with the functional power of the heart which may finally lead to irreparable myocardial weakness. 2. Adherent Pericardium (Chronic Pericarditis, Mediastinopericarditis) Adherent pericardium results from either acute or subacute inflam- mation. Stokes, Gardner and Walshe understood the results of pericardial adhesions. Their consideration of the results of adherent pericardium is unequaled DISEASES OF THE PERICARDIUM 431 by anything which has appeared since, with the exception of Broadbent’s treatise on the subject. Barlow and Chevers were agreed that hypertrophy and dilatation of the heart were not necessary sequences of obliteration of the heart sac or uncomplicated adherent pericardium. Walshe proved that after adhesions an atrophic condition of the muscle was more likely to result. In the light of more recent clinical data as reported by Krehl and Romberg, with pathologic observation, the fact is fully corroborated that hypertrophy or dilatation never follow complete obliteration of the pericardial spaces and that the heart itself may not be unfavorably influenced. With mediastinopericardial and pleural adhesions, fixation of the heart to the thorax, and the systolic retraction which is associated with adherent pericardium, immobile thorax often follows. The heart is forced to overexert, it dilates, it hypertrophies and may finally break; marked fibroid and atrophic changes follow. This is most likely to occur with asso- ciated valvular defects. In some cases, particularly where there are mediastinal pleuroperi- cardial adhesions, the x-ray examination will offer valuable assistance. With mediastinal, pericardial and pleural adhesions the veins at the base of the heart may be compressed leading to marked secondary changes in the heart and in distant organs. Probably the dilatation which exists in a large number of adherent hearts is due more to the diseased condition of the heart muscle than to pericardial interference. When hypertrophy follows in these cases the idght heart is usually most enlarged, the hypertrophy becomes a necessity because it must overcome the effect of preceding dilatation. In many cases in which the heart itself is tied down to the chest wall at some point or to the surrounding tissues, the prognosis will depend very largely upon the ability of the heart to help itself by increasing its muscular fibre, hence its systolic strength. Adhesions early in life interfere materially with the development of the heart. Adherent pericardium with arteriosclerosis, especially coronary disease, is threatening. The combination may end life without warning. The heart muscle always remains the paramount issue in the prognosis of adherent pericardium, for in many cases there is either consecutive or preceding myocarditis, as often happens for example with tuberculous pericarditis. Moderate superficial fatty degeneration of the myocardium, originally described by Virchow, is not often of serious significance. Adherent pericardium, mediastinal and pleural agglutination with added work thrown upon the heart muscle because of increasing valvular disease, asthma and emphysema, recurring bronchiolitis, kyphosis or pneu- monia (usually bronchopneumonia), advancing arteriosclerosis, chronic 432 DISEASES OF THE CIRCULATORY APPARATUS interstitial pneumonia (which often follows chronic mediastino-pleuro- pericarditis) becomes a serious condition which continues during long pe- riods to threaten life, usually with evidences of extreme dilatation and dropsies, and causes death. In connection with tuberculous pericarditis with adhesions I mention the influence of the operation of Cardiolysis of Brauer on these cases (See Cardiovascular Tuberculosis). The literature of this subject is sufficient with our present experience to prove the enormous influence of the opera- tion of Brauer on adherent pericardium and the “fixed thorax”—“Starrer Thorax”—of the Germans. Adherent pericardium with general tuberculosis, valvular disease, nephritis or other grave constitutional defect offers an unfavorable outlook. Adherent pericardium may persist during many years with but few symptoms and without shortening life. 3. Chronic Pericardioperitonitis ('Chronic Polyserositis, Pick’s Disease, Zuckerguss Krankheit) Curschmann and Pick both called attention to productive changes in the serous coverings of the peritoneum, the liver, the spleen, the pleura and the pericardium in which there is enormous fibrous thickening of the various serous coverings with the characteristic appearance which follows the deposit and the drying of a saturated solution of white sugar on a smooth dry surface, to which Curschmann therefore gave the name of “Zuckerguss Krankheit.” The various serous membranes seem to be simultaneously affected or the inflammation of one covering may follow close upon the other. The pericardium may become adherent, the sac obliterated, always with enormous thickening. Pari passu, with the changes in the pericardium and peritoneum, ascites develops. The ascites persists during many years without causing death; to prolong life repeated tapping is necessary. In two cases seen during the past ten years we were obliged to tap on an average of once every four to six weeks. In several of our cases there was hydrothorax and hydropericardium with ascites. The spleen is often much enlarged, its serous covering so thickened as to be unrecognizable. The liver shows organic changes which suggested to Pick the name of "pericardial pseudocirrhosis of the liver.” In all of these cases the obstruction of the portal circuit is the leading symptom, the evidences of chronic peritonitis persist, the pericardium may be deeply involved without causing serious subjective manifestations, but at some stage of the disease the myocardial weakness is sure to develop DISEASES OF THE PERICARDIUM 433 and leads to increasing circulatory embarrassment, extensive dropsies, cyanosed kidney and death, unless intercurrent disease interferes earlier. The evidences of pericardial thickening and obliteratiort may be so few as to make the positive anatomic diagnosis impossible. It may be assumed that with Pick’s Disease which has persisted during a long period, the pericardium and multiple serous surfaces are thickened, particularly if the patient is an alcoholic and with recurring ascites shows evidences of myo- cardial weakness with pleural changes. One of our cases lived over twenty years and died as the immediate result of an ill advised laparotomy, the surgeon having diagnosed tubercu- lous -peritonitis. One boy who came to the hospital when about 12 or 13 years of age was observed during eight years and disappeared. The average length of life is between ten and fifteen years, during which paracentesis abdominalis and in some cases repeated aspiration of the thorax are necessary to prolong life. Patients who do not die of myocardial degeneration usually yield to intercurrent disease, pneumonia frequently. The process being multiple, radical surgical interference offers no encouragement. I have found death hastened by it. 4. Hydropericardium The accumulation of fluid in the pericardial sac when non-inflamma- tory in its origin is usually the result of stasis, interference with the nor- mal emptying of the veins and lymphatics of the heart, an accompaniment of all possible heart lesions, changes in the walls of the blood vessels due to constitutional diseases, including the anemias and leukemias, hydremic conditions and chronic nephritis. The fluid is usually of low specific gravity, often contains sugar and chyle. With heart lesions and hydropericardium there is usually dilatation of the ventricles. The prognosis of hydropericardium is grave because it depends entirely upon an underlying cause which is usually serious; the accumulation is likely to be a terminal complication. 5. Hemopericardium The presence of pure blood in the pericardial sac may be due to trauma- tism, to the rupture of small or large pericardial vessels, to the rupture of an aneurism, either of the heart, aorta or coronary artery or other large vessel, including the pulmonary artery, also malignant growths. 434 DISEASES OF THE CIRCULATORY APPARATUS With hemorrhages of considerable size, collapse is prompt, anemia characteristic, the pulse small and death not long postponed. Compression of the heart by the surrounding blood is an important factor in causing death. 6. Pneumopericardium This condition is exceedingly rare. I have no record of a case in my own practice. Walter James collected 38 cases of which 26 died. Traumatism, rupture of esophageal or gastric cancer, surrounding ab- scess or ulceration, instrumentation followed by accidental perforation of the esophagus, trachea or lung, empyema, pyopneumothorax with tubercu- losis and adhesions, have been known to cause pneumopericardium. The effect on the heart depends upon the cause of the pneumopericar- dium. External causes leading to prompt surgical interference, improve the patient’s chances of living. Internal perforations promptly lead to suppurative (purulent) peri- carditis and usually to death. When for some reason a small amount of air enters the pericardium without causing purulent or other pericarditis, it may be absorbed without interfering with the functions of the heart and unless the underlying cause is serious the patient is likely to recover. 7. Neoplasms of the Pericardium The leading new growths of the pericardium are tubercle, carcinoma, sarcoma and gumma. Tuberculous pericarditis is separately considered; it is always second- ary to disease in other organs (See Cardiovascular Tuberculosis). When cancer invades the pericardium the disease is likely to extend from the immediate neighborhood. The larger number of sarcomata of the pericardium are spindle or round celled and never primary. Gummata of the pericardium are always associated with myocardial syphilis, either single or multiple, with muscle degeneration. All new growths of the pericardium cause some symptoms of pericar- ditis, usually with effusion which is blood stained or purulent. The prognosis of pericardial new growths is absolutely had. Barlow.

Defective Ventricular Septum. 3. Perforate Foramen Ovale. 4. Dextrocardia. 5. Stenosis of the aortic orifice. 6. Insufficiency and stenosis of the mitral and bicuspid valves. 7. Transposition of the aorta and pulmonary artery; perforate and premature closure of the ductus arteriosus. It is by no means easy to diagnosticate with anatomic precision the location of congenital defects in all cases where one or more exist, for the subjective and objective manifestations of all are much the same and several are likely to be present in many cases. 1. Stenosis of the Pulmonary Orifice Stenosis of the Pulmonary Orifice causing obstruction of the pul- monary valve with narrowing of the conus arteriosus of the right ventricle is the most frequent of all congenital heart defects (GO per cent). Of those who live with congenitally defective hearts after the twelfth or thir- teenth year, over 80 per cent show pulmonary stenosis. When only mod- erate, and stenosis of the pulmonary orifice or the vessel exists, without other defect, compensatory hypertrophy of the right ventricle makes it possible in the absence of added complication for the subject to live many years in good health. These patients are often conscious of the murmur, hut disregard it and are not materially inconvenienced. 436 DISEASES OF THE CIRCULATORY APPARATUS If with pulmonary stenosis there is perforate foramen ovale—a fre- quent combination—the patient’s chances of living are materially reduced. It is unusual for such patients to live beyond the fifteenth year; to live longer is exceptional. With stenosis and a defect in the intraventricular septum, life is rarely prolonged beyond puberty. Most of these die during the first years of life. The right ventricle hypertrophies enormously to send the blood into the aorta. With pulmonary stenosis, patent interventricular septum and open for- amen ovale the forecast is graver than with stenosis alone. Peacock says “the open state of the foramen ovale and the imperfection in the ventricu- lar septum, so far from adding to the danger, really afford the means of relief to the overcharged right auricle and ventricle without which life could not be prolonged for any considerable period.” This “relief,” how- ever, is comparative and under the slightest stress or with complications proves insufficient. Congenital pulmonary stenosis is usually coexistent with auriculoven- tricular lesions or other evidences of fetal endocarditis. Fetal endocarditis is not infrequent and is a cause of congenital steno- sis and other defects (B. Fischer). Pulmonary stenosis with patent ductus arteriosus (Botalli) leads to early death. Colbeck says “life is rarely prolonged beyond the thirteenth year.” Complete occlusion of the pulmonary artery leads to early death. With a high degree of stenosis the blood which reaches the lungs must pass from the aorta through the ductus arteriosus which latter remains open. When stenosis of the pulmonary orifice is the only congenital defect, there is a fall of pressure in the pulmonary artery, the pressure in the pul- monary veins is elevated, also in the right ventricle with consecutive hypertrophy of both right auricle and ventricle. In many of these cases there is marked cyanosis. In some cases tricuspid insufficiency is super- added. Pulmonary stenosis and perforate foramen ovale with closed inter- ventricular septum was found by Abbott in 12 per cent of her cases of congenital heart lesions. This makes it possible for much of the blood to find its way along the channel of least resistance through the opening from the right to the left auricle without going through the lung. Natu- rally the amount of cyanosis will then depend upon the quantity of Mood which finds its way through the lungs via, the pulmonary artery. When these conditions prevail, it takes but the slightest added effort, such as exercise, overeating and emotion, leads to prompt increase of cyanosis and dyspnea. Peacock found that 74 of 101 of his cases were “blue babies” morbus CONGENITAL DEFECTS OF THE HEART 437 coeruleus) at birth, or they showed characteristic cyanosis before the end of the second year. Cyayiosis, dyspnea, convulsions, headaches, clubbed fingers and poly- cythemia are the leading features of this and most congenital anomalies with associated physical signs. Nosebleed and purpuric conditions are also frequent. (For a detailed account of the physical signs of congenital heart de- fects and further pathologic data, the reader is referred to Hirschfelder’s classic work on “Diseases of the Heart and Aorta” (Lippincott, Philadel- phia and London) and Maude Abbott’s article (Vol. IV. Osier’s Modern Medicine). Almost all who live long enough with congenital stenosis of the pul- monary orifice develop pulmonary tuberculosis. Abbott reports 80 per cent. B. Fischer (personal communication) says that all who live beyond the fifteenth year show tuberculous changes in the lungs. Increasing enlargement of the liver, spleen, with cyanosis, albumin- uria and ascites in the average case do not continue long before death follows. Blood counts during all stages of all congenital defects are interesting. The polycythemia of pulmonary stenosis with septum defects may reach as high as 9,000,000, even higher. Hirschfelder gives Stoelker’s statistics showing “53 cases with 32 deaths at birth, 12 during the first year and 11 during the first decade. Only 4 reached the fourth decade.” Abbott’s statistics are also quoted by Hirschfelder. Age at Death. Pulmonary Stenosis. Pulmonary Atresia. Ventricular Septum Closed. Foramen Ovale Closed.

Defective Interventricular Septum We have referred to the defects of the interventricular septum in the preceding paragraphs. The defect was an accompaniment of other anomalies in 78 per cent of Abbott’s cases (149). In 58 per cent of these there was stenosis or atresia of the pulmonary orifice or artery. In 24 cases, i. e., 16.1 per cent the ventricular septum defect was uncomplicated. We are rarely called to offer a prognosis in cases of defective ventricular septum for the condition per.se is not usually diagnosticated. The defects which are coincident, justify the prognosis given in considering stenosis of the pulmonary orifice with this complication. Uncomplicated defects of the septum have been found post mortem in subjects as old as fifty years. 3. Perforate Foramen Ovale Uncomplicated perforate foramen ovale is the least serious of all con- genital defects; it may not cause symptoms. There are many cases in medical literature showing life to have remained uninfluenced; death being due to other causes. The influence which the open foramen exerts on the more frequent pulmonary stenosis is considered in the preceding para- graphs. Associated mitral lesion may lead to recoil of blood from the left to the right auricle, to venous stasis and cyanosis—a serious and life-threatening complication. Emboli may form and reach the pulmonary artery from the left ventricle and pass to remote parts of the body causing fatal infarcts. 4. Dextrocardia Dextrocardia, without other serious lesions, is usually associated with the transposition of other viscerae and exerts little influence on life. It has been thought by some to predispose to acute infections but there are no positive data which bear on the subject. 5. Stenosis of the Aortic Orifice Stenosis of the aortic orifice may be due to fetal endocarditis or to the congenital displacement of the aortic septum and the unequal division of the aorta and pulmonary artery. The result of stenosis of the aortic orifice is invariably hypertrophy of the left ventricle. If the aorta is completely closed, the left ventricle re- mains undeveloped and the circulation is carried forward through the right ventricle assisted by the perforate ductus arteriosus. The prognosis is grave, but few survive birth. Abbott found this defect in 2 per cent of her cases. CONGENITAL DEFECTS OF THE HEART 439 The length of life of subjects with stenosis of the aortic orifice depends largely on the narrowness of the opening and the associated lesions. If the interventricular septum is patent but few live after the ninth or tenth year. Stenosis of the first portion of the aorta and stenosis of the arch of the aorta at the ductus arteriosus may develop congenitally. Abbott reports this lesion in 198 of her 412 cases—a common anomaly therefore. With a well compensated collateral circulation life may not be shortened, though the heart may suddenly revolt, the peripheral vessels dilate and tire, offer no assistance, cerebral hyperemia may prove serious and fatal. 6. Insufficiency and Stenosis of the Mitral and Tricuspid Valves Insufficiency and Stenosis of the mitral and tricuspid valves of con- genital origin depend upon fetal endocarditis. Romberg calls attention to the fact that complete closure of the tricuspid may exist when the blood is conveyed through the perforate foramen ovale and a slit or leak in the ventricle. 7. Transposition of the Aorta and Pulmonary Artery Perforate Ductus Arteriosus and Premature Closure (Botalli) Occasionally transposition of the aorta and pulmonary artery with or without transposition of the auriculoventricular valves is found. In some cases there is either absence or partial deficiency of the septum between the aorta and pulmonary artery allowing the two vessels to communicate. The ductus arteriosus normally closes within the first week after birth; failure to close leaves the opening between the aorta and left branch of the pulmonary artery. Patent ductus arteriosus as already mentioned is, as a rule, combined with pulmonary stenosis or aortic narrowing. Uncomplicated patent ductus arteriosus may give rise to no symptoms, and may not interfere with life; its presence remains unsuspected and is discovered post mortem. When uncomplicated, the symptoms are not con- tinuous but recurring cyanosis and dyspnea may at times prove trouble- some. Transposition of the aorta and pulmonary artery promptly leads to death; it is incompatible with continuance of extra-uterine existence. It is often surprising to find the subjects of congenital heart defects 440 DISEASES OF THE CIRCULATORY APPARATUS looking robust; the lesions are irreparable and as Adelman has recently said, they remain “infaust,” “the sword of Damocles hangs over these children.” While the lesions do not heal, the physical signs may often change, murmurs disappear or their character is modified. Most congenital heart defects show insufficiency at birth and therefore many die during the first month of life or shortly after. If life is prolonged beyond the first year they may live for several years without severe symptoms because of a degree of compensation. The heart muscle becomes an important factor. With increase of weight, extra work is thrown upon the crippled organ to meet the demands of development, and a break is likely to follow. Tuberculosis and other pulmonary complications are the most frequent causes of death in those who live beyond the eighth or tenth year. Tuber- culosis, the most frequent complication of pulmonary stenosis, does not develop during the first years of life. Death may take place while children are crying or exercising, during excitement, emotion, from acute, often insignificant infection, during con- vulsions or with other cerebral complications. In many cases, repeated x-ray examinations will prove of inestimable value for both diagnostic and prognostic purposes; by this method com- pensatory efforts can be watched. Each case demands separate consideration; there are no rules which are of value; extreme pictures may improve temporarily, cyanosis and dyspnea threatening at one time may disappear to recur later. Severe dyspnea and persistent cyanosis with edema are always un- favorable. Cyanosed kidney, scanty and albuminous urine or nephritis are un- favorable complications. The character and frequency of the pulse, i. e., the condition of the heart muscle remains the most prominent prognostic guide with congenital as with all other heart anomalies. References Abbott.

DISEASES OF THE MYOCARDIUM 441 E. Diseases of the Myocardium The myocardium influences prognosis oftener than does any other organ of the body. In this chapter I consider those conditions which are associated with change of myocardial function usually due to degenerative and toxic, rather than to inflammatory lesions. It is repeatedly demonstrated in this work that with many constitu- tional conditions the myocardial degeneration or cardiac toxemia is the direct cause of death. It is unnecessary to repeat in this chapter what is thoroughly consid- ered in connection with the myocardial changes as they complicate the separate infections diseases; to these the reader is referred for details. The same may be said of the results of myocarditis or, more properly speaking myocardial degeneration as found in the majority of lesions of the heart, including the endocardium, and the valves. These are also separately considered. I have aimed to impress upon the clinician the overpowering influence of the myocardium in the prognosis of all internal diseases whenever involved. The hypertrophy and dilatation of the heart resulting from, or associ- ated with valvular defects, arteriosclerosis, kidney lesions, syphilis and many other individual diseases have also received separate consideration. Idiopathic Hypertrophy of the Heart.—There are cases of idiopathic hypertrophy of the heart in which the most careful search fails to show valvular lesions, arterial or kidney disease. Ho cause can be given for many of these hypertrophies. Some of these die with dilatation after a period of cardiac asthenia, including the usual features of broken compen- sation. In occasional cases there may be few pericardial adhesions. In some of these cases death is caused by bullet shaped thrombi which, as Jores showed, form by predilection between the trabeculae of the right ventricle. These cases of idiopathic hypertrophy of the heart ultimately prove to be due to degenerative and myocarditic lesions. There is another type of idiopathic hypertrophy in which both halves of the heart are enlarged, dilatation is not marked, it is usually absent, the heart muscle is of a reddish brown color without characteristic micro- scopic appearances. There may be stasis in vital organs, there is usually slight arteriosclerosis of the abdominal aorta and of the renal arteries. Neither the arteriosclerosis nor the renal lesions are sufficient to be con- sidered causative of the hypertrophy. These cases strengthen the theory of Bollinger that cardiac hypertrophy and arteriosclerosis are “coordinate processes of the same cause.” Idiopathic hypertrophy is often associated with polycythemia, very 442 DISEASES OF THE CIRCULATORY APPARATUS often in alcoholics and without arterial and kidney changes. This condi- tion is frequent in beer drinkers, the heart may ultimately become fatty. Idiopathic hypertrophy is also found in growing children without known cause. Most of these subjects finally develop dilatation which con- tinues during a varying period and leads to death. The following lesions of the myocardium will be considered: 1. Acute Purulent Myocarditis. 2. Acute Interstitial Myocarditis (Parenchymatous Myocarditis). 3. Chronic Myocardial Insufficiency. (a) Fibroid degeneration (including the arhythmias). (b) Fatty heart. (c) Fragmentation and Segmentation. (d) Brown Atrophy. (e) Coronary sclerosis with associated myocardial degenera- tion. (Angina Pectoris.) (f) Senile Heart. 4. Hypertrophy and Dilatation due to, (a) Overstrain. (b) Hypertension. (c) Secondary to lung diseases, asthma, kyphosis, fixed thorax, and non-valvular heart lesions. (d) With masturbation, uterine fibroids and Hyperthyroidea. 5. Stokes-Adams Disease. 6. Syphilis of the Heart. I. Heart Weakness due to insufficient exercise. 8. Inherent muscular weakness. 9. Insufficiency with the anemias, metabolic faults and toxic states. 10. Neoplasms. II. Parasites. 12. Rupture of the Heart. 13. Aneurism of the Heart. 1. Acute Purulent Myocarditis Acute purulent myocarditis is of septic embolic origin; it is usually an accompaniment of malignant endocarditis, localizes itself as a rule in the right conus arteriosus and in the papillary muscles of the left ventricle, may lead to embolic abscesses, necrosis and even to heart rupture by ulcer- ation. The prognosis is always unfavorable, death follows a period of positive symptoms including petechise and the other usual manifestations of septic endocarditis. DISEASES OF THE MYOCARDIUM 443 2. Acute Interstitial Myocarditis (Parenchymatous myocarditis) Acute interstitial myocarditis and parenchymatous myocarditis may he: (a) Simple acute interstitial myocarditis, (b) Acute septic interstitial myocarditis. (a) Simple Acute Interstitial Myocarditis (Romberg) These conditions have been fully considered in connection with diph- theria, typhoid fever, scarlet fever, smallpox, gonorrhea, rheumatism, measles and other infectious diseases. In some cases the parenchymatous changes are in the ascendency. Some are of the mixed type showing both interstitial and parenchymatous changes. The prognosis depends largely on the virulence of the primary infection. (b) Acute Septic Interstitial Myocarditis Acute septic interstitial myocarditis is almost always fatal. It is a serious question whether the differentiation made by Aschoff of (1) Acute purulent myocarditis and the (2) Acute interstitial septic myocarditis requires consideration for clinical purposes. Anatomic diag- nosis during life is impossible. The prognosis of both of these septic proc- esses is unfavorable. 3. Chronic Myocardial Insufficiency (a) Fibroid Degeneration (“Weak Heart” Debilitas cordis, Myodegeneration of the Heart, Myocardial degeneration) Myocardial degeneration is the most frequent of all lesions of the heart causing death. It is a disease of advanced life; when found early in life it usually leads to prompt death if not due to syphilis. Women are not as often affected as men, and when they are the disease shows itself later than in men. The heart lesions which are increasing with surprising rapidity are of a degenerative fibroid character, they progress insidiously without marked physical or subjective symptoms during a long period; the patients present for treatment as a rule, after the initial stage, when complex conditions exist. It may be assumed that the degenerative 'process is brought about by interference with the proper nourishment of the heart muscle through the coronary arteries. The result is sclerotic or fibroid, change in the mus- 444 DISEASES OF THE CIRCULATORY APPARATUS culature of the heart. The heart in these cases passes through a period during which it is overtaxed because of faulty pabulum to its muscle ele- ments and there is usually a long existing and unrecognized hypertension with added toxic conditions. The influence of faulty metabolism, long continued worry and strain, syphilitic infection and obstructive changes in the peripheral capillaries as found with arteriosclerosis of the kidney and mesenteric vessels is of paramount importance for prognosis and etiology. An overworked heart with peripheral obstruction and associated high blood pressure is likely to yield when extra demand is made upon it. This is particularly true when there is advanced coronary disease. Cases de- tected in the initial stage without marked distant (arteriosclerotic) changes and not progressive, which are tractable and able to follow the directions of the physician, are often favorably influenced by treatment. The prog- nosis will depend entirely upon the associated conditions, the capacity of the myocardium, which can he tested by safe methods, the age of the patient, and the underlying cause. Conditions are often complex even in the early stage of myocardial weakness and in many cases make prognosis exceedingly difficult, often impossible. If during the initial stage there are attacks of stenocardia (angina pectoris) and these are severe, the chances of materially prolonging such a life are small (See Angina Pectoris). Early evidences of stasis, particularly enlarged liver and spleen with cardiac asthma are among the unfavorable features, as are also dyspnea and symptoms referable to the peripheral vessels. It is unfortunate for many of these cases that the patient is often unconscious of myocardial disease until the heart reserve has been ex- hausted. The symptomatology associated with similar lesions is so vari- able in different cases, as to mislead the clinician and the patient. Mac- kenzie says that “at first sight the ‘symptoms’ are hopelessly confused.” “I have submitted to Professor Keith a large number of hearts affected by the changes associated with arteriosclerosis from patients ranging from forty-two to seventy-seven years of age, and in all the post mortem appearances had such a close resemblance that it might have been assumed, that during life the symptoms would have been identical.” This how- ever is not the case. Some patients suffer from serious anginous attacks and in the intervals present no evidences of myocardial disease, while others with exactly similar lesions present the continuous symptoms of muscular weakness; still others present no evidences of any lesion in either subjective or objective symptoms, but suddenly, there is either an acute dilatation, a pulmonary edema, the development of arhythmia, extra systoles, suddenly arising evidences of extreme muscular insuffi- ciency, the pulsus alternans and prompt death. Others develop dropsies, DISEASES OF THE MYOCARDIUM 445 while with exactly the same lesions there are often no dropsies. The functional disturbances therefore are differently influenced in different cases by the same lesions. It is impossible for the physician as Allbutt has said to draw a parallel “in the living patient between the formidable works of decay described by the pathologists; how and when these degen- erations are manifested; how, in the long course of cardiac decay the imminence of death is to be foreseen and provided against; or how, in- deed, we are to know that any such process is at work at all; or lastly, how in a case of known heart disease the degrees of its advancement and of the cardiac reserves are to be noted and tested.” “Thus we have the physician and the pathologist trotting each on his own side of the hedge, each intent upon his own scouting and his own bearings, and neither able as yet to reconcile his own observations with those of his comrade.” The blood pressure study of fibroid degeneration offers varying results. Early high blood pressure (hypertension) with symptoms of myocardial degeneration sufficient to make the diagnosis possible is as unfavorable as hypotension with the same subjective complaints. Sudden decided fall of blood pressure with small and rapid pulse and distant heart sounds is always evidence of insufficient heart power. High blood pressure, without evidences of coronary involvement in subjective symptoms, without aortic insufficiency, without arhythmia, with or with- out an aortic systolic murmur, but with the pulse pressure approaching the normal (40 to 60 mm. Hg.) may be considered favorable for the continues tion of life, and the patient is often able to continue his occupation if it is not too taxing, mentally or physically. These patients are materially influenced by autosuggestion; the personal element plays an important role, and the prognosis is often improved by the tactful consideration of existing conditions with abundant and justified reassurance and the judi- cious planning for the future. Too much importance has been given to systolic blood pressure by the lay world, often by the physician, without a just estimate of the many col- lateral conditions to be considered in all cases of myocardial degeneration. High systolic blood pressure with myocardial fbrosis in patients be- yond 55 years is often without unfavorable effect. There is a class of cases in which the myocardial degeneration progresses rapidly; it in- cludes men who work under unusual strain who often develop hyperten- sion which is promptly followed by hypertrophy of the left ventricle, and for some reason the associated kidney cirrhosis progresses with equal rapidity. The prognosis of these rapidly developing cases is bad. The duration of some, from the beginning of the subjective symptoms which brought the patient to the physician to the end, has been less than four months. These are exceptional conditions. The revolt of the myocardium in the terminal stage is associated with dyspnea, erratic heart action and nocturnal pulmonary edema in some, cardiac asthma in others. 446 DISEASES OF THE CIRCULATORY APPARATUS Early evidences of edema are nob encouraging neither are the symp- toms of stasis within the portal circuit (Liver engorgement and gastritis). Pallor with vertigo arising suddenly, with or without arhythmia, particularly on slight exertion, are warnings of weakness, which when un- heeded lead to serious results, at times sudden death. Physical signs which show marked dilatation and embryonic heart sounds in any stage of fibroid or any other form of myocarditis are always suggestive, worse with dilatation of the left than the right ventricle. With angina pectoris and myocarditis the ventricles are not dilated as a rule, though the outlook may he exceedingly grave. With emphysema, chronic bronchitis and marked kyphosis the evi- dences of right ventricular dilatation are often borne during long periods and with improved conditions (often possible) the dilatation disappears. Accented second pulmonic sound is always evidence of insufficiency of the mitral valve and with fibroid degeneration the insufficiency is likely to he relative. The advanced and unfavorable symptoms often follow an acute exac- erbation ; an angincus seizure or a suddenly arising cardiac asthma, or nocturnal pulmonary edema may be followed by continuous symptoms of decompensation. Severe dyspnea may persist after such acute attacks and may never disappear. In a number of cases evidences of stasis in the liver and dropsies of the serous cavities (hydrothorax, hydropericardium, occasionally ascites and edema of the extremities) develop; marked arhythmia becomes continuous, there is albuminuria with reduced urine, excessive nervousness, finally orthopnea and death ends the scene. Physical examination of the heart in the terminal stages shows marked dilatation of the left ventricle; systolic murmurs over the mitral and aortic areas are frequent, the second pulmonic sound is accented and with hypertension and interstitial nephritis the second aortic sound is also snappy and loud. In another class of cases the heart is so exhausted that the sounds are indistinct, distant and embryonic in character. With increasing weak- ness, the heart becomes rapid and as already suggested arhythmia is a further evidence of myocardial insufficiency. There are cases of serious fibrosis of the myocardium in which the pulse gives absolutely no indications of the existing condition—this is of great importance. Even with normal frequency, rhythm and blood pres- sure, advanced degeneration may be present and increase rapidly. A normal pulse which is markedly influenced, i. e., accelerated by slight exertion, is always suggestive of myocardial degeneration. Persist- ent rapidity, as well as marked bradycardia and instability as shown by decided variation in the frequency and character of the pulse are serious. Experience teaches that a heart which has been overtaxed or in which a lesion has been recognized which, suddenly becomes erratic or shows that DISEASES OF THE MYOCARDIUM 447 its reserve is being reduced by the development of any form of arhythmia, is an organ which demands a guarded prognosis. Many such hearts may again “find themselves,” but they are not dependable, such organs are eas- ily fatigued, they revolt on slight cause, are likely to desert when but little overtaxed, they dilate unexpectedly. On the other hand favorable cases are met which after serious evidences of weakness regain sufficient force to live in comfort with proper care during long periods. “In no organ is this lack of concord between the signals of life and death so disconcerting as in the heart.” (Allbutt.) The Arhythmias The irregularities of the heart which interest the clinician in connec- tion with myocardial degeneration are: (i) Sinus irregularities. (ii) Irregularities due to depressed conductivity. (iii) Irregularities due to extrasystoles (premature contractions). (iv) Pulsus alternans. (v) Auricular fibrillation. By the use of graphic methods we are now able to gain information for diagnosis and prognosis which have metamorphosed cardiac pathology. By the simultaneous study of the jugular and the arterial pulses we now obtain a clear conception of the clinical significance of, and the factors which cause the arhythmias. In this work we concern ourselves with the prognostic significance of. the separate arhythmias, basing our conclusions on the work of Mackenzie, Lewis, and Price. i. The 'prognostic significance of Sinus irregularities The usual form of sinus irregularity is of little prognostic signifi- cance. Lewis excludes “the prolonged and sudden cessation of the heart beat and the true phasic variation of pulse rate.” Sinus irregularity is not frequent with myocarditis but is usually found in young subjects and in those who have been taking digitalis. ii. Irregularities Due to Depressed Conductivity We do not include all of the fully developed Stokes-Adams phenomena in this consideration. (See Adams-Stokes Complex.) The prompt impulse along the auriculoventricular bundle is disturbed or delayed with depressed conductivity. Price suggests three grades of impairment: (1) The stimulus from auricle to ventricle is merely de- layed—that is, there is merely a prolongation of the interval which sepa- 448 DISEASES OF THE CIRCULA TORY APPARATUS rates the commencements of contraction of the auricle and contraction of the ventricle. (2) The stimulus does not at times cross over; in other words, the ventricle does not at times respond to the stimulus from the auricle (this is called “partial heart block”) and (3) no impulses at all reach the ventricle from the auricle, so that the auricles and ventricles beat quite independently of each other, the ventricles at an approximate rate of 30 per minute (“complete heart block”). Our clinical experience teaches that heart block of any form with myo- carditis is a serious condition, it certainly indicates a diseased and weak- ened myocardium. In all forms of irregularity due to depressed conductivity there is great danger from sudden cerebral anemia and revolt of the heart muscle which may lead to sudden death. We are not considering the temporary disso- ciation of febrile disease in which the prognosis is fairly good, but the graver condition which is due to an organic and permanent change in the myocardium. iii. Irregularities Due to Extrasystoles (Premature Contractions) Extrasystoles represent the commonest of all intermissions—an extra- systole is a premature contraction either of the auricle or ventricle or of both together, while the sinus rhythm is maintained. The normal rhythm of the heart is interrupted by either frequent, or occasionally by a premature beat; the following pause is abnormally long which is termed the “compensatory pause.” The beat which follows is more powerful because of the long period of rest after the extrasystole. The pulsus bigeminus is due to a regularly recurring extrasystole after each normal heart beat. Feeble extrasystoles may not be felt at the wrist, the pause simply is recognized as “dropped beat” or intermittent pulse. Extrasystoles are most frequent during middle life and directly after, in men oftener than in women, and oftener with fibroid myocarditis (cardiosclerosis) than with valvular disease. The Mackenzie school does not consider extrasystoles as bearing seriously upon prognosis. The con- sensus of the modern school is summed up in the following quotation, “Unfortunately the public has come to attach a serious significance to them, (extrasystoles). This is absolutely without foundation. When extrasystoles are considered by themselves, that is, without reference to the condition with which they may be associated—there is no evidence for supposing that extrasystoles can be taken as an indication of an impaired heart or add to the gravity of an already diseased heart.” (Price.) To this Mackenzie and Lewis subscribe. We are, however, dealing with myo- cardial fibrosis, and while many cases live for years with extrasystoles DISEASES OF THE MYOCARDIUM 449 the arhythmia must be considered indicative of a diseased myocardium and should never be disregarded though its importance is less than are most other arhythmias. I know that extrasystoles accompany grave heart lesions and safe reasoning leads the clinician to the conclusion that the associated lesions must give their own prognostic indications. Wr, do not deny the possibility of a healthy heart falling into the bad habit of producing premature contractions. The work of the degenerated heart muscle will certainly be increased finally by the presence and per- sistence of extrasystoles, and in direct proportion to their frequency— Lewis, it seems to us offers the safest conclusion. “Premature contrac- tions constitute and bear witness to defects” . . . “while premature con- tractions have unquestionably a relatively insignificant import, as com- pared to many forms of cardiac irregularity, entire neglect of their pres- ence is not advisable.” iv. Pulsus alternans With the alternating pulse, the heart beats regularly, blit each alter- nate beat is larger than the beat immediately preceding, hence with the contraction of the left ventricle the quantity of blood thrown into the aorta is larger and smaller at alternate contractions. The size of the pulse is necessarily influenced and the tracings are correspondingly clear. Alternate pulse is sometimes found when the heart contracts with un- usual frequency as with paroxysmal tachycardia, under such conditions it is less serious than in those cases with which it is most frequently asso- ciated, i. e., when the heart rate is not accelerated; the pulse may be of normal frequency or even reduced in frequency with fibroid myocarditis, angina pectoris, hypertension with chronic interstitial nephritis and in all forms of decomposition associated with dilatation of the heart and fatigue. The pulsus alternans is evidence of an overtaxed heart; it means that the heart is struggling to carry its burden, that its reserve is exhausted, and it always adds to the gravity of the case and is always serious. Lewis says “It ranks with subsultus tendinum, with optic neuritis, with the risus sardonicus and other ill-omened messengers. It is the faint cry of an anguished and fast failing muscle, which, when it comes, all should strain to hear, for it is not long repeated. A few months, a few years at most and the end comes.” The alternating pulse, being a symptom of advanced myocardial degeneration, is associated with other grave symp- toms in most cases, these include angina pectoris, hypertension, nocturnal dyspnea, often with pulmonary edema or cardiac asthma, Cheyne-Stohes breathing, or it may be the only evidence of a crippled myocardium which suddenly balks when death is entirely unexpected. “These results support the teaching of Dr. Mackenzie. In his expe- 450 DISEASES OF THE CIRCULATORY APPARATUS rience, the inception of the pulsus alternans in aged people has invariably been followed by fatal heart failure within two or three years.” (Windle.) Windle in his article on “The Incidence and Prognostic Value of the Pulsus Alternans in Myocardial and Arterial Disease” offers the follow- ing in Table 1 Pulse irregularities observed in 202 cases of arteriosclerosis: Nature of Irregularity. Number of Cases Observed. Percentagf 109 54.5 Complete irregularity 61 30.5 23 11.5 3 1.5 1 0.5 Complete heart-block 4 2.0 Sinus irregularity 1 0.5 y. Auricular Fibrillation (Auricular Flutter) The “flick” or “flutter” of the auricle with fibrillation is rapid, erratic and is produced by “stimulus production at multiple auricular foci.” A large number of irregularities are due to auricular fibrillation. The in- fluence of auricular fibrillation on the ventricle according to Lewis is twofold. “The normal regular and coordinate contractions in the auricle are in abeyance and consequently the ventricle is robbed of the regular impulses which form its accustomed supply. These are replaced by numer- ous and haphazard impulses, escape to the ventricle from the turmoil which prevails in the upper chamber; the change is consequently pro- found.” The condition is most frequent during advanced life when degenera- tive processes are numerous. It is not present during the first decade of life. It is more frequent in men than in women. It is a frequent accompaniment of mitral stenosis. Lewis says “Mitral stenosis and auricular fibrillation are bosom companions.” Ventricular fibrillation is promptly fatal, and is the cause of sudden death in a number of cases. Auricular fibrillation is synonymous ivith muscular degeneration of the auricle and characteristic of advanced changes. It is the precursor of cardiac surrender in many cases—in other DISEASES OF THE MYOCARDIUM 451 cases tlie heart learns to accommodate itself to the flutter and cases are recorded which lived ten years and longer after the initial seizure. In some favorable cases the fibrillation is paroxysmal. The frequency of the beat influences prognosis; the more frequent the flutter the greater the danger of exhaustion. The results of digitalis treatment on auricular fibrillation influences the forecast. The drug in favorable cases acts as a specific and promptly controls the symptom, if it fails■, the prognosis is absolutely bad. The conclusions of Gossage and Braxton Hichs are appended: “1. That the exact cause of auricular fibrillation is unknown. “2. That it usually comes on in a heart where there has been for a considerable period disease of the valves or myocardial change from inflammation or degeneration. “3. That it sometimes arises suddenly where there has been no pre- vious sign or symptom of heart disease. “4. That possibly in some of these cases it occurs in hearts which were previously perfectly healthy. “5. That if this is true its essential cause must lie outside the heart and not in any anatomical or pathological change in the heart itself. “6. That sudden death in auricular fibrillation is probably due to the onset of fibrillation of the ventricles, and that some cases of sudden death both in diseased and healthy persons may be due to the simulta- neous onset of fibrillation of both auricles and ventricles.” The prognostic significance of the Atropin reaction in diseases of the heart has received considerable attention from various sources. The hypodermic injection of 1/50 to 1/25 grain of atropin produces a de- cided increase in the heart rate by paralyzing the pneumogastric. It acts directly on the vagus and not on the myocardium. Cushny first sug- gested “releasing of the vagus by means of hypodermic doses of atropin, so-called atropin reaction in the study of digitalis action” (Talley). The polygraph or sphygmograph is used to register the pulse rate and to show the contrast. The rate is to be averaged by ten minutes’ observation before taking the hypodermic, the reaction is again averaged by ten minutes’ observation, when after .the injection, the pulse is at its maximum. The normal reaction is from 30 to 40. Talley should be consulted for a full understanding of the method, his conclusions follow: “1. The atropin reaction in the normal heart is probably from 30 to 40. “2. A reaction of 20 or less, in a heart not recently subjected to exhausting disease, points to a degenerative process in the cardiac tissue which makes the outlook for improvement under treatment unpromising. “3. Cases of auricular fibrillation with normal response or above, are promising subjects for treatment. 452 DISEASES OF THE CIRCULATORY APPARATUS “4. Two atropin reactions in case of auricular fibrillation, one before and one on full digitalis, enable us to determine whether the vagal or the cardiac tissue factor is the greater. The patients with a large cardiac tissue factor are the ones who usually are sufficiently improved by treat- ment to return to their occupations.’’ Fibroid myocarditis once established is never cured. It can be con- trolled m many cases by rational living. Its extent naturally influences the prognosis as well as the course of many associated conditions. Sudden death occasionally occurs without previous warning of the existence of any lesion. This is not frequent. But few die in whom a thorough consideration of symptoms and physical examination would have failed to lead to a correct diagnosis. Diabetes, gout, and other diseases, as well as a faulty diet for metab- olic faults, the use of thyroid extract for obesity, continued mental strain, acute disease, particularly influenza, often prove depressing factors which promptly invite progression of existing degeneration. The fate of the myocarditic patient often depends on his own acts. It is surprising to note how many of these patients with weak hearts (degenerated) continue to live in favorable surroundings and conditions with a minimum of symptoms during many years, when they give the heart the rest which it needs. Errors of diet, excesses of any kind, may promptly shorten life, which with rational treatment, temperance and sobriety might have continued during a considerable period. The effect of tobacco, tea, coffee, alcohol and sexual indulgence de- mands the closest scrutiny in the individual case, and if the patient wishes to prolong his life, he must be willing to make sacrifices and forego many pleasures. In favorable cases the effect of rest and treatment is comparatively prompt and is followed by the disappearance of threatening symptoms. (6) Fatty Heart Fatty disease of the heart may be due either to the accumulation of fat in the sub pericardial tissue, which may also deposit between the mus- cular fibers of the heart, a condition found with obesity, at times with carcinoma and tuberculosis, or to the “fatty degeneration of the heart” in which the muscular tissue has undergone a fatty degeneration, which may be diffuse or more or less localized. The heart cavities are dilated, hypertrophy is impossible in advanced cases because there is insufficient muscle element left; the heart is therefore usually flabby and dilated. With obese patients the small and feeble organ is insufficient to meet the demands made upon it by the enormous body when the changes are advanced. The association of obesity with coronary sclerosis, and a DISEASES OF THE MYOCARDIUM 453 high diaphragm to which Romberg calls attention is an unfavorable combination. In many obese subjects the two forms of fatty disease are combined. When with fatty accumulation in obese subjects there is also fibroid myocarditis the prognosis is bad. In obese subjects with diabetes and gout, a combination which is not infrequent, or with diabetes alone, the evidences of heart fatigue and insufficiency may arise suddenly, and promptly end fatally. Whenever an obese patient develops arhythmia suddenly9 it is proof of cardiac insufficiency and is serious. Fatty degeneration of the heart is also found with all wasting dis- eases, pernicious anemia, with phosphorous poisoning, pericarditis, endo- carditis and with the myocarditis of many acute infections. The myocardial degenerations are not infrequently of the mixed type, i. e., fibroid and fatty degeneration or parenchymatous may be present together. So long as the heart muscle itself in the obese subject is intact and the deposit of fat in the surrounding tissues is not serious, the danger lies in the invasion of the myocardium—the extent of fatty and fibroid degeneration. Leyden holds that in such cases dropsies have been overcome. This in our experience is exceedingly rare. The influence of diet and carefully supervised exercise and the Ber- gonie treatment is favorable in occasional cases. With dilated hearts in obese subjects and evidences of stasis, the prognosis is grave. Arteriosclerosis and obesity with heart symptoms develop conditions which advance insidiously and lead to death. The increase of dullness to the right of the sternum is less serious than similar increase to the left of the nipple line which is proof of dila- tation of the left ventricle. The former is often due to fatty deposit rather than degeneration. The prognosis of fatty degeneration of the heart is primarily influ- enced by its cause. With the acute infections under proper it may disappear or cause no further symptoms after fully established convalescence; the sarqe is true of anemic conditions which are amenable to treatment. Feeble and distant heart sounds with dilatation, relative mitral insuf- ficiency, dyspnea, arhythmia, faintness, syncope, cyanosis, and stasis in the abdominal viscera, are among the unfavorable features of fatty heart. Fatty degeneration due to coronary disease is usually of the mixed fatty, fibroid type and is fatal. Rupture of fatty heart is a frequent cause of death./ One such case we met during a gall-stone colic. Sudden death during gall-stone or other colics {renal) is at times due to fatty 454 DISEASES OF THE CIRCULATORY APPARATUS and insufficient heart. In Y7 per cent of fatty hearts Hamilton reported spontaneous rupture. (c) Fragmentation and Segmentation Fragmentation and segmentation cannot be diagnosticated ante mor- tem, they interest the pathologist. The true significance and cause of fragmentation is undecided. Post mortem, the heart muscle with frag- mentation shows transverse breaks or fractures across its fibers; with segmentation, the muscle fibers themselves are separated along the line of contact. Fragmentation has been found in hearts without degenerative changes and may be due to ante mortem or post mortem changes. id) Brown Atrophy Brown atrophy is frequently found with chronic valvular disease in the senile heart and with cachectic states. The heart is small and usually insufficient. When brown atrophy exists during a comparatively long period fibroid changes are also found in the myocardium. With the small heart of brown atrophy there is feeble systolic force and hyotension. The prognosis depends on the cause; brown atrophy can only he sus- pected during life, never positively diagnosticated. Starvation Atrophy.—The enormous tolerance of the heart makes full recovery possible after atrophy due to starvation and long continued wast- ing disease. (e) Coronary Sclerosis (Angina pectoris) Seneca wrote of angina pectoris, “To have any other malady is to be sick; to have this is to he dying.” John Hunter, himself a victim of Heberden’s disease and his con- temporary, said “my life is in the hands of any rascal who chooses to annoy or tease me.” We have no clearer or more classic picture to offer of angina pectoris than is included in the original description of the disease by Heberden in his Commentaries on the History and Cures of Disease. In the pres- ent state of our knowledge reasoning from the prompt appearance of the symptoms of angina when the heart muscle is taxed in those suffering from the disease, whatever the lesion found on post mortem, we are justified in including the complex with the diseases of the myocardium DISEASES OF THE MYOCARDIUM 455 and subscribe to the dictum of Mackenzie “that angina pectoris is an evidence of exhaustion of the function of contractility” and that the pain “is a viscerosensory reflex.” Coronary disease is unquestionably the leading lesion of angina pec- toris. It is associated in a proportion of cases with aortic disease— aortic aneurism, simple dilatation of the aorta, aortic valvular disease and in but few cases do ive fail to find myocardial degeneration, a result of faulty nourishment through the coronary vessels. Hypertension is often associated with some o?ie of the above men- tioned lesions, but is by no means a constant attendant of the disease either during the paroxysm or in the interval. Fiessinger contends that the danger to life of angina pectoris has been somewhat exaggerated and divides cases of the disease into six groups, according to the cause, viz.: coronary involvement, aortitis, myocarditis, interstitial nephritis, obesity and aerophagia—this order of enumeration is that of decreasing gravity. The exhausted left ventricle is an important attendant of angina pectoris in all cases. In most cases the ventricle is struggling against an increased pressure, this relieved, the sensory symptoms are long post- poned or may never recur. It has been the experience of all clinicians to find the fading of anginous attacks with the appearance of ventricular dilatation and mitral insufficiency. Musser, Broadbent, Mackenzie, Abrams, and Eisner report similar experiences. The heart during the attacks is perceptibly reduced in size; with broken compensation and dilatation the prognosis so far as angina pectoris is concerned is better in direct proportion to the amount of dilatation. After severe illness, the symptoms of angina pectoris often disappear. Ortner mentions such cases. We include in our series the case of a woman who almost twenty years ago had typical angina wdth chronic nephritis and advanced aortic lesion. She developed uremia, passive cerebral hyperemia, was unconscious during a long period with a threat- ening pulse, she finally rallied from the acute symptoms and never again had the slightest suggestion of coronary spasm. I count among my cases a number of men and women in whom there was complete recovery from anginous symptoms during many years after the development of added heart and kidney lesions. One of these was a clergyman who had severe angina during several months when he was stricken with vague febrile symptoms associated with marked cerebral manifestations; he made a full recovery from these and for nineteen 456 DISEASES OF THE CIRCULATORY APPARATUS years continued at the head of a large congregation when he developed anew the symptoms of angina with nephritis. I do not consider “pseudo angina3 a disease per se. There are occasional cases of pain and other associated symptoms in which it may be assumed that there are no lesions in the coronaries or heart muscle but which are due to vaso-constriction or spasm of the arteries, in which the symptoms of stenocardia are of secondary origin. Nothnagel’s article on “Angina pectoris vasomotoria” describes these fully. These patients are easily influenced by cold, after and during exposure they have the characteristic pang, and this is likely to persist until they are thoroughly warmed. My experience is in accord with that of Mackenzie that the blood pressure is not high in these cases either during the attack or in the interval. The prognosis of vasomotor angina is more favorable than is that of other forms of the disease. The enormous increase of stenocardia, or coronary disease is striking. This is especially true among professional men. In 6,155 cases of in- ternal disease I found 110 fully developed (1.78 per cent) coronary scleroses. This is in striking contrast to the rarity of the disease during the days of Benjamin Bush; out of his enormous experience he reported in a lecture to his students that he had seen but one case of angina pec- toris, and he mentioned the name of a colleague practicing in Philadelphia who had also seen but one case. Coronary sclerosis may truly be considered “the doctor’s disease” for it is more prevalent among physicians than among any other class of men. Over 80 per cent of deaths among the teaching medical faculties of the large universities of the world during the past ten years have been due to this disease. Bomberg has said that arteriosclerosis is most advanced in the vessels which are most taxed; physicians tax their hearts and brains most, hence their coronaries and cerebral vessels must bear the burden. There is no disease of the arterial tree in which family history is a more striking pathogenic and prognostic factor than in angina pectoris. It is not at all uncommon to find several members of a family in which the father or mother had fully developed angina pectoris. With a strong family tendency to the disease, the symptoms, are likely to develop in the fourth decade, occasionally in the third, and the course of the disease is more rapid than when developed later in life. My experience justifies the statement that almost all cases of angina pectoris developed before the fortieth year are either associated with a direct hereditary tendency or are of syphilitic origin. In the subjects burdened with heredity there is usually an unrecognized period of hyper- tension and the development of the complex is hastened sooner than it is in other subjects who are exposed to the same hurry, worry and overwork. When we consider the prognosis of angina pectoris from the purely DISEASES OF THE MYOCARDIUM 457 clinical manifestations which are produced, two pictures stand out in bold relief. First. The large attack, suddenly arising, usually after excitement, worry or a hearty and full meal, in which the anguish is great, the pain severe, breathing uninfluenced as a rule, a sense of impending death, the sensation of a heavy load resting on the thorax, at times the “heart is pressed in a vise,” blood pressure presents no distinctive features, it may be high, is usually however nearly normal or may be slightly depressed; the pulse is equally non-committal, it may be slow or normal, if the attack is long there may be extrasystoles; with advanced myocardial degenera- tion, there may be great rapidity, the pulse small and sometimes alter- nating. The pulse in many cases seems entirely unchanged from the normal, to the moment of death. The heart may suddenly stop during diastole often at a time when its systolic force seems reassuring. Second. The small attack. The majority of cases which now present, suffer from the “small attacks”; these are suggestive of the larger attack but are less severe and in many cases, after the disease has continued during a varying period, are likely to recur on slight cause; they are eva- nescent and the varying sensations described by different patients promptly cease with rest. In the advanced cases the small attacks are promptly provoked by the slightest extra tax on the heart, but they are rarely associated with the severe pain of the larger attacks, neither does the pain often radiate from the sternal regions into the neck or beyond the left shoulder; the patient is not materially weakened by recurrence. Each one of the large attacks has been said to “add a peg to the coffin”; the smaller attacks are often borne during many years without serious results in patients who profit by rational living. The first larger attack may kill the patient; as a rule there are several larger attacks before the fatal termination. The large attack may never recur, the patient may fall into a condition of chronicity covering many years during which he has many small attacks, or several months or years may intervene after which severe attacks follow. It is impossible, in the absence of physical signs, to give a prognosis of value. No disease presents more prognostic problems than does angina pec- toris. uThe cardinal fact in real angina is its (Walshe). The small attacks rarely kill, they make the lives of the victims wretched and uncertain; they do not often interfere (nor should they) with light occupation, and with care the patients may continue to live during many years. I have found that the effect of vasodilators offer valuable prognostic data. Angina pectoris (either large or small) which is promptly relieved by small doses of glonoin, given dry on the tongue, offers a favorable fore- cast so far as the prolongation of life is concerned. Thus many men who have angina pectoris, by the aid of infinitesimal doses of glonoin are 458 DISEASES OF THE CIRCULATORY APPARATUS able to take exercise and prevent serious symptoms during long periods. This effect is by no means the result of suggestion. The author has given the method too many trials to be mistaken. Cessation of activity during the first moments of a large or small attack has a favorable effect in most cases. Large or small attacks recurring during rest or during the night, arousing the patient from sleep are always serious, they indicate advanced disease. Women hear angina longer and better than do men. They are better able to rest and their worries are fewer and their activities more limited. Large or small attacks in young subjects unless specific, are more likely to end life sooner than are similar seizures in older subjects. Arhythmias persisting or arising during attacks are an expression of myo- cardial weakness. Extrasystoles are easily borne during years by many who suffer from the milder form of the disease. Persistent and intensive antisyphilitic treatment in the presence of a positive Wassermann reaction offers a good chance of complete cure. The number of cases associated with aortitis prove the frequency of syphilis as a cause. Closure of both coronaries leads to prompt death. One coronary may be sclerosed during a long time without causing death. The trunks may be atheromatous tracing them into their intra- muscular network to find the finer branches free from disease and thus there is sufficient blood to maintain the heart wall and prevent serious revolt. With aneurism and aortic disease and angina, the prognosis is abso- lutely bad. With aortic insufficiency and coronary disease (a frequent combina- tion), there is constant danger and death is not long postponed. Evidences of aortic (valvular) degenerative change (arteriosclerotic) with coronary disease and small attacks with slight hypertrophy of the left ventricle and a reasonably dependable blood pressure are found in many cases which live for years, are always in danger; they hold their lives in their own hands. Indiscretion is not long tolerated in these cases. An aortic systolic murmur should not always be seriously interpreted, for it is present in many cases which live many years. A single debauch, a single error of diet, with the overloading of the stomach, may lead to prompt death. These are the cases which are reported by laymen and often by physicians as uacute indigestion.” uAcute indigestion” does not kill a man with a normal heart. Thrombosis or embolism of the coronaries is a frequent cause of death. It cannot be influenced by any known treatment. Acute dilatation added to coronary sclerosis either during an attack or in the interval, if extreme, DISEASES OF THE MYOCARDIUM 459 is serious; moderate dilatation which may he provoked by forcibly strik- ing the cervical vertebrae with a percussion hammer often relieves the attack and saves the patient. Osier has called attention to angina pectoris as an early symptom of aortic aneurism. Anginoid attacks occur in children with valvular disease and with adherent pericardium. I have seen a number recover, particularly with valvular defects, our experience with adherent pericardium in chil- dren has been limited. In the adult, I saw one case in which cardiolysis cured the patient, a physician who is now engaged in active practice. Angina pectoris of toxic origin offers a favorable prognosis if the coronary sclerosis and myocardial degeneration are not too far advanced. Tobacco angina is amenable to rational treatment, as are also those indefinite cases attributed to tea, coffee, etc. When symptoms persist in spite of discontinuance of the supposed cause, it may be concluded that grave organic disease exists. Abdominal angina (dyspragia intermittens intestinalis et abdominalis of Ortner) is due to sclerosis of the superior mesenteric artery, as a rule; it may alternate with angina pectoris, or the coronaries may not be in- volved. The prognosis depends on the extent of the general process. With abdominal angina life may be materially prolonged in most cases. Interstitial nephritis with angina, is usually associated with marked hypertension and advanced arteriosclerosis. In these cases death is not often due to the coronary disease directly; most of our patients have died of uremia or other complications. Sometimes there has been a period of decompensation without recurring angina, but with dropsies. In all cases of angina pectoris excessive coitus, at times even moderate indulgence, influences the case unfavorably. Pulmonary edema has complicated a number of our cases immediately following coitus. Agreeable occupation is necessary in those cases which are about; idleness and a self-centered state increase all symptoms. In no other disease of the cardiovascular system is the patient so promptly influenced by his psychic condition. The exalted and over- wrought brain is associated with the tear which often kills these patients. The painful seizures accompanying Graves’ disease yield to treat- ment. It is questionable whether they belong among the true anginas. There are occasional neuroses which justify the term “anginoid”; these are all symptomatic and offer a good prognosis. In all cases the condition which caused the symptoms must give the data upon which the forecast should rest. This requires of the physician the most painstak- ing investigation of all details, a task which is not without its reward. The severest “large attack” in which the life of the patient seems lost may yield and the patient may live to enjoy life, while the “smaller 460 DISEASES OF THE CIRCULATORY APPARATUS attack,” almost unnoticed, if neglected may lead to death. This is not the rule. I repeat—the prognosis is unfavorable in proportion to the ease with which the attack is produced by seemingly insignificant causes, in cases with marked arterial degeneration, with hereditary tendencies, with carelessness of the patient, under unfavorable surroundings and social conditions, failure, to rest, with associated progressive metabolic faults, gout, diabetes, lead-poisoning, added acute infections and with pneumonia. Self cure of angina pectoris is possible. The revelations of the Rontgen rays are needed in all cases to assist in clearing the horizon and often lead to valuable data for prognosis. The task of the physician in conveying to the patient the necessary infor- mation to lead him safely over a path which is never without danger is by no means easy. Enormous tact is required to prevent the autosugges- tion which is harmful and which aggravates existing conditions. To absolutely ignore the dangers invites prompt death; to pilot with intelli- gence, with concert of action of the attendant and the patient often adds many years of life. What this means to mankind is apparent, when we consider the intelligence and the usefulness of those whom the disease attacks by predilection. (/) Senile Heart Balfour is probably responsible for the final acceptance of the “senile heart” as presenting a complex of symptoms which may justify the diag- nosis. Senile heart is not a clinical entity. The symptoms depend upon degenerative changes in the cardiovascular system of the aged or prematurely old and include all of the usual clinical manifestations of such complex lesions with myocardial weakness in the- ascendency. The prognosis depends upon the extent of the myocardial and arterial disorganization; it is always unfavorable, though the subjects of “senile heart” cautiously guarded, may live quietly during many months. 4. Hypertrophy and Dilatation Hypertrophy and dilatation due to: (a) Overstrain Permanent or transitory dilatation and hypertrophy of the heart mav follow severe strain, undue muscular exertion and prolonged worry. The possibility of preexisting disease of the heart, or its muscle must always be considered. In the majority of these cases the history will prove that the heart was not normal before the strain. DISEASES OF THE MYOCARDIUM 461 Undue strain long continued may certainly lead to hypertrophy. In Erance the country letter carriers, who walk all day, suffer no ill effects from their long continued, and at times laborious marches, prob- ably because the normal heart, more than any other muscle, accommodates itself to its work. Rieder, Spillman, Bernheim, Thurn, assert that with a healthy condi- tion of the heart it is exceptional to find cardiac insufficiency and dilatation with consecutive hypertrophy following severe bodily exercise, and most of these observers believe that the normal heart never tires, that in those who are perfectly healthy in spite of exhausting effort there is no typical cardiac insufficiency. A full consideration of this subject leads us (Eisner) to the conclusion previously expressed. “It is safe and conservative to conclude, that the heart muscle, like all muscles, demands the natural stimulation which fol- lows moderate functional activity and mechanical movements, but ex- cessive functional activity, mechanical strain or prolonged mental pang and worry, cause malnutrition and irritation, giving rise to chronic degenera- tive changes” and may lead to hypertrophy and dilatation. This hyper- trophy may take place in the perfectly healthy heart and is not to be considered pathologic. In making life insurance examinations it should be remembered that the hearts of young men and growing boys often show marked increase of systolic force and slight hypertrophy of the left ventricle. This is par- ticularly true of the college student who is at all athletic, and should not argue against the acceptance of the risk. These hypertrophied hearts due to overwork which are to be included in the class of “work hypertrophies" never show degenerative changes if they were previously absolutely normal. The “overtrained” heart which was previously normal, which during periods of stress shows the effects on the cardiovascular system, after a time, varying in different cases, as a rule, returns to its normal condition and remains so. These experiences have been confirmed by many ob- servers (Inndell). (b) Hypertension The influence of hypertension is considered with the separate condi- tions with which it is associated, and requires no repetition in this chapter. I once more warn against misinterpretation of the prognostic value of blood pressure study, agree that long continued hypertension is a frequent cause of hypertrophy, that most of these cases are associated with estab- lished arteriosclerosis and renal involvement ivhen detected, that its early detection and rational treatment often leads to satisfactory results, that in itself “raised blood pressure . ... is productive of degenerative changes in the vessels" .... Lauder Brunton further says “we have good 462 DISEASES OF THE CIRCULATORY APPARATUS grounds for believing that if the rise be detected early, and counterbalanced bv proper regimen and treatment, the vascular changes which it would otherwise produce might be prevented and life very considerably pro- longed.” (c) Hypertrophy (Secondary to lung diseases, asthma, kyphosis, fixed thorax and non- valvular heart lesions) The prognosis of the hypertrophy secondary to the diseases above men- tioned requires no separate consideration, it must necessarily depend upon the seriousness of the underlying pathologic lesions. It is surprising to note the salutary influence of hypertrophy on the general condition of these patients; in most cases it may safely be considered compensatory and therefore favorable. Extreme sudden dilatation occasionally causes sud- den death or serious decompensation. Fixed thorax and some non-valvular diseases of the heart including hyperthyroidea with marked hypertrophy are often favorably influenced by surgical interference. This is true of the former (Starrer-Thorax), a fact not generally understood by the profession. (With masturbation, uterine-fibroids and hyperthyroidea) (d) Hypertrophy With masturbation the heart is often irritable and overactive, the sys- tolic force abnormally strong. These symptoms are associated with mod- erate hypertrophy, which yield with the dropping of the habit, and leaves no remnants. Uterine growths are often associated with enlargement of the thyroid Sind, other symptoms of hyperthyroidea and heart hypertrophy. I have called attention to this frequent association of uterine, thyroid and heart lesions in an article (Eisner) which proves this possibility and its unusual frequency. All abdominal growths by pressure and added circulatory obstruction add to the work of the heart muscle. With uterine myofibromata of con- siderable size it is not surprising to find the myocardium insufficient with- out the loss of blood from flooding. The prognosis of the heart condition has been studied in the French hospitals, particularly by Pozzi, it is favor- ably influenced by surgical interference. A small uterine polyp may cause heart symptoms, often continuous, and when persistent, hypertrophy may result; removal brings relief. DISEASES OF THE MYOCARDIUM 463 5. Stokes-Adams Disease {Heart Block) The Stokes-Adams complex when fully established (See also reference in this chapter to Irregularities due to depressed conductivity) is an ex- pression of advanced disease of the bundle of His making it impossible for impulses to reach the ventricle from the auricle; the ventricles and auricles heat independently of each other. The phenomena of heart block include, bradycardia, epileptiform seizures, often syncope, visible auricular im- pulse in the neck, the rhythm usually 3 to 1, in all cases myocardial disease, often, positive evidences of arteriosclerosis. The myocardial lesion always includes change of some kind in the auriculoventricular bundle (His fibers). Lewis grouped his cases as follows showing the age distribution of Stokes-Adams disease: Age 10-20 20-30 30-40 40-50 50-60 60-70 70-80 90-90 Cases 7 6 3 5 2 3 4 1 The symptom complex may occur at any age; the age distribution de- pends on the diseases which produce it. The rheumatic and choreic cases include most cases between 10 and 35 years. The specific and arteriosclerotic group includes the cases between 35 and 70. The senile group includes a large number of cases with asso- ciated heart lesions. Our series of cases shows the disease to he twice as frequent in men than in women. Lewis calls attention to the presence of heart block with the acute in- fections in young subjects, particularly with rheumatism, diphtheria, in- fluenza, typhoid, and pneumonia. Our chronic cases have been either in the subjects of previous rheuma- tism, syphilis or with marked arteriosclerosis. Heart block is often found during and after acute infections, or with valvular lesions in which large doses of digitalis have been responsible for the dissociation. Heart block is always serious, it is in almost all cases the evidence of local disturbance which is a part of a widely disseminated process, just as a small placque over a coronary artery is a limited hut fatal lesion of far- reaching arteriosclerosis. Heart-block may be borne during long periods by some, but when the pulse falls to a very low level (15-25) the epileptiform, at times apoplecti- form state clouds the sensorium and death after convulsive movements 464 DISEASES OF THE CIRCULATORY APPARATUS follows. The larger number of deaths are due to the associated fibroid degeneration, uremia at times, cerebral apoplexy and sudden acute dilata- tion of the left ventricle. The mild rheumatic type and those cases of partial block associated with the acute infections entirely disappear during convalescence. The specific cases offer a better prognosis when intensive treatment is instituted, than do the arteriosclerotic or fibroid types. I have in pri- vate and hospital practice seen encouraging results from the combined modern treatment (mercury and neosalvarsan) (Weintraud, Huchard, Barries). Heart block, properly speaking, should include only those cases in which complete block does not exist; Stokes-Adams disease represents cases of complete block. The occurrence of convulsions always increases the danger, though it must be conceded that they are more frequent with partial, than with com- plete block. In my experience no patient has recovered in whom the underlying cause was of degenerative origin; the only recoveries included in the series were the syphilitic and those acute cases in young subjects, dependent on infection, rheumatism usually, pneumonia and influenza. Most acute in- fections which are sufficiently severe to include the complex, lead to death during the active days of the toxemia. The longest duration of Stokes-Adams disease in my experience was in a man who for fifteen years had persistent bradycardia, his pulse beat v/as below the average of the respiratory frequency at all times, he had epileptiform seizures at varying intervals during three years before his death in coma. Ilis age at death was 79. I have had no experience with the so-called "neurotic cases” described by Edes and Councilman, which fail to show pathologic lesions on post mortem examination. Death is usually sudden. Sapegno found lesions of the auriculoven- tricular fibers in 50 per cent of all sudden deaths. Sternberg found some lesion of the bundle in 70 per cent of cases of all heart affections. 6. Syphilis of the Heart See Cardiovascular Syphilis 7. Heart Weakness due to Insufficient Exercise The myocardial weakness which results from insufficient exercise is often an accompaniment of long continued invalidism, or is due to other DISEASES OF THE MYOCARDIUM 465 causes; at times the inertia of the patient and paralytic conditions make exercise impossible. The heart muscle may weaken in aged patients with fractures, usually of the hip joint. There may be alarming syncope when the patient first tries to change his position or stands, but the heart soon gathers strength and' in the absence of organic change become normal. 8. Inherent Muscular Weakness There are occasional cases of inherent muscular weakness with an asthenic state, in which the myocardium promptly shows evidence of fatigue on slight cause. Such hearts bear any added tax badly; the patient is without resistance and when overtaken by infection is unable to make the average fight against its advance. Children who are constitutionally weak, in whom there is a distinct diathesis, may be influenced by many factors to overcome the inherent weakness, which, when it persists, leads to an unhappy existence. I have found a number of these cases of inherent weakness among the intractable cases of Akinesia algera originally de- scribed by Moebius, which may lead to years of invalidism and which offer a doubtful prognosis (See Akinesia algera). 9. Insufficiencies with the Anemias, Metabolic Faults and Toxic States Myocardial insufficiency is likely to develop with the advance of all of the graver anemias, with faulty metabolism and with many toxic condi- tions. The prognosis must depend entirely upon the character of the primary disease and cannot be separately considered. 10. Neoplasms IsTew groivths of the heart are either primary or secondary. The gumma of specific origin is of greatest interest to the clinician; all other growths are interesting pathologically, but remain as a rule undiagnosti- cated during life. The primary growths are: Fibromata Myxofibromata Lipomata Lymphangiomata Cavernous myomata Rhabdomyomata. Myxomatous growths may form on the separate valves. 466 DISEASES OF THE CIRCULATORY APPARATUS The secondary or metastatic growths are: Carcinomata (often from the esophagus) Tubercle Syphilitic gummata Lymphadenomata Extension of Hypernephromata Sarcomata Melanosarcomata X anthosarcomata Osteosarcomata. Direct invasion of the heart from the pericardium may follow sarcoma of the thymus, cancer of the lung and pleura. Leukemic growths may also invade the myocardium. The Stokes-Adams complex follows invasion of the intraventricular septum occasionally with neoplasms; with syphilitic gummata, this is comparatively frequent. Some of the innocent growths, when small, may give rise to no symp- toms during life, the malignant and semimalignant naturally hasten the death of the victim. Tuberculosis and actinomycosis are separately considered. 11. Parasites of the Heart The Echinococcus may find a resting place in the heart muscle (See Hydatid disease) usually in the right ventricle and unless of considerable size, causes no symptoms. When the cyst ruptures, embolic infarcts lead to death. These are found in the lung and distant organs. The Cysticercus of the Tenia solium may settle in the myocardium. When symptoms are produced by the growing cyst, they never lead to a diagnosis. Marked hypertrophy, dropsy and severe pectoral pains pre- ceded death in the few recorded cases. I have had no personal experi- ence with either Echinococcus nor Cysticercus of the heart. We have found the heart infected with Trichinae spiralis, hut their presence in the heart muscle as a rule does not materially influence the prognosis of trichi- nosis, so far as we know (See Trichinosis). For a full consideration of the parasites of the heart the reader is re- ferred to Hosier’s articles. (See reference.) 12. Rupture of the Heart I referred to rupture of the heart in connection with fatty heart and mentioned the fact that in 77 per cent of spontaneous ruptures Hamilton found fatty degeneration of the myocardium. DISEASES OF THE MYOCARDIUM 467 13. Aneurism of the Heart Aneurism, of the heart is exceedingly rare; it is an occasional cause of rupture. It may accompany ulcerative malignant endocarditis and fibroid myocarditis. Fibroid degeneration and the mixed forms of degeneration may also lead to aneurism and rupture. Partial rupture may not prove immediately fatal. We found one case in which a partial rupture preceded death by a number of days, which was sudden and due to a second complete rupture. A thrombus may plug a small rent and prolong life during only a limited time. Abscess of the heart wall may cause rupture—the majority of heart abscesses are micotic—are found with malignant endocarditis, pyemic and septic conditions—they may be multiple or single.

Endocarditis Endocarditis is either (1) acute or (2) chronic. 1. The varieties of Acute Endocarditis are: (a) Simple Acute Endocarditis (Thrombo-endocarditis simplex of Ziegler). (b) Septic Endocarditis. (Malignant or ulcerative endocarditis, Thrombo-endocarditis sep- tica ulcerosa) (Aschoff) 2. The varieties of Chronic Endocarditis (Chronic Cardiopathy) are: (a) Valvular Deformities (resulting from previous Acute Endo- carditis) (b) Degenerative Endocarditis (Arteriosclerosis—Syphilis) Endocarditis is always of infectious origin, is secondary and not a disease per se. To recognize its prognostic significance its pathology demands consid- eration. The extent of the endocardium, the unevenness of its surface, as well as its irregularity, the mechanical factors continually present, invite the deposit and proliferation of bacteria. The endocardium offers a suitable and inviting culture medium, more particularly with changed conditions of the blood, and possible slight ab- normality of the endocardial surface. This is especially true of the malig- nant, septic or ulcerative type of endocarditis. ENDOCARDITIS 469 1. Acute Endocarditis (a) Simple Acute Endocarditis (Thrombo-endocarditis simplex of Ziegler, also known as Endocarditis verrucosa) The prominent lesion of this form of endocarditis is the deposit of warty or papillary masses or bodies along the edges of the valves. The amount of deposit varies; it may be so insignificant as to escape the eye, or it may be prominent, forming masses of considerable size—uneven, irreg- ular and of warty appearance. These masses on section show the character of thrombi, and hold within the included fibrin, platelets, lymphocytes with colonies of the infecting bacteria. There may be evidences of necrosis of the tissue of the endocardium or valve upon which the warty or papillary masses rest. The extent of the necrosis is in direct proportion to the severity of the infection. The danger of embolic infarct increases with the extension of the necrosis and the loose attachment of the thrombi. The replacing of the thrombi and of the underlying endocardium by connective tissue in the process of cure, including the valve structure, result in thick- ening, contraction, adhesions, leading to stenosis (narrowing) or insuffi- ciencies in accordance with the extent of the original lesions. Endocar- ditis may limit its ravages to the free surface of the endocardium without involving the valves. This fact must be considered in the diagnosis and prognosis of infections in which unexplained symptoms of constitutional disturbance persist. The following figures show the relative frequency of the invasion of the valves: The mitral valve is involved in 60 per cent; the aortic in about 9 per cent. The tricuspid and pulmonary rarely; the inflammation of both mitral and aortic valves is found in about 30 per cent of all cases. With simple endocarditis it is exceedingly rare to find the tricuspid inflamed with the mitral alone, or with the mitral and aortic valves combined. It is unusual to find all four valves attacked (Aschoff). In simple endocarditis the bacterial invasion is not usually overpower- ing, there is limited loss of endocardial tissue, there may be none at all, the formation of emboli is infrequent—all these conditions prevail in the septic or malignant type of the disease—hence the prognosis so far as life is concerned, is good. Romberg denies the possibility of complete anatomic restitution after even simple acute endocarditis. The extent of the damage done by an acute endocarditis cannot be foretold—this fact calls for a guarded prognosis concerning the future of the functional powers of the heart and at the same time suggests such prophylactic measures as should lead to the conservation of the organ. All forms of acute endocarditis are associated with more or less myocarditis, 470 DISEASES OF THE CIRCULATORY APPARATUS a further fact, which must he considered in connection, with the primary disease during the period of endocardial involvement and the months fol- lowing convalescence. Pericarditis (See Chapter Pericarditis) is also a frequent accompaniment of endocarditis; the significance of the former must be considered in connection with the degree of virulence of the primary infection and the extent of the endocarditis, as well as the charac- ter of the effusion. (See Pericarditis.) The mortality of the combined lesions reaches between 25 and 35 per cent. All factors which overtax the heart during or after acute endocarditis invite permanent damage. Endocarditis is subject to relapses; this is due to the tendency of poly- arthritis to recur (the most frequent cause of the complication) ; and the further fact that the endocardium harbors bacteria in its folds and on its surface during long periods. In the acute types, non-malignant, the left ventricle is usually the seat of the infection; with severer and ulcerative septic endocarditis, the right heart is frequently the seat of profound changes as well as the left ventricle. I have considered the significance of endocarditis in connection with the many infections which it complicates and refer the reader to the sep- arate chapters; they include Polyarthritis, Scarlet fever, Tonsillitis, Typhoid fever, Pneumonia, Erysipelas, Diphtheria, Chorea, Syphilis, Tuberculosis, Gonorrhea, Pyemia, Sepsis, Nephritis, etc. With some forms of grave anemia and cachexia, endocarditis may de- velop and seriously complicate the prognosis. Probably some of these cases are of toxic rather than of infectious origin. Endocarditis complicating gout, diabetes and other constitutional dis- eases, may, in the light of our present knowledge be included in the “toxic type.” The prognosis with acute symptoms and material change in the heart muscle is to be guardedly given; all features of the case demand the closest consideration. These cases are not to be confounded with the endocarditis of degenerative (arteriosclerotic) origin which is frequent with faulty metabolism. The Physical Signs.—In offering a prognosis, the clinician is not to interpret the loudness of the systolic murmur which is present and widely disseminated over the precordium in almost all cases, as indica- tive of a serious condition. Let the greater reliance for prognosis be placed upon the virulence of the infection, the extent of the primary lesions, the general condition of the patient, the amount of dilatation of the heart, the character of the pulse, the functional ability of the kidney, the blood pressure, the size of the liver (enlarged in serious cases), the size of the spleen, the presence of infarcts, the blood picture and a variety of symptoms which are unearthed by close observation, In children, while the prognosis is less favorable than in adults, iu ENDOCARDITIS 471 the absence of edema and in the presence of apparently serious endo- carditis, recovery may follow with but limited damage to valvular structures. Even with edema and multiple systolic murmurs in children and adults, recovery may folloiu ivith surprisingly insignificant damage in cautiously treated cases. Loud, and multiple murmurs with chorea, may disappear entirely, never to return, within a number of years. Return of chorea may in some cases remain uncomplicated, in others there are acute exacerbations of endocarditis. The prognosis of chorea with complicating endocarditis is not bad. In a large experience I have seen but two deaths; both chil- dren were enormously obese—in one the endocarditis was malignant. With recurrences and extension, the damage resulting with increas- ing physical signs of myocardial insufficiency arid dilatation, may lead to long periods of uncertainty, but in most cases life is saved; occasion- ally underlying conditions are serious, resistance is reduced and death cannot he averted. Pulmonary edema, pneumonia, purulent pericarditis, thrombosis, embolism with hemorrhagic infarct and a mitral obstructive lesion are unfavorable complications, and include the most frequent causes of death. Duration.—It is never possible to foretell the length of time during which the acute symptoms will continue; cases which often drag along dur- ing weeks and months without change in physical signs or subjective symp- toms, gradually regain health with ultimate limited damage to the heart. The previous condition of the heart is an important factor in prog- nosis. There is always danger of malignant endocarditis in cases of acute exacerbation of chronic heart lesions. With early aortic insufficiency, the danger is greater than with the more frequent mitral insufficiency; the danger is greater with early mitral than with aortic obstruction. The influence of age, sex, occupation and habits is considered with the resulting permanent valvular lesions. In all cases of simple acute endocarditis treatment, especially rest and right living enormously influ- ences prognosis. Many lives have been doomed to wretchedness and chronic invalidism by failure on the part of the physician, oftener the patient, to realize the great curative and prophylactic value of rest after acute endocarditis. (6) Septic Endocarditis (Malignant, Infectious, Ulcerative Endocarditis; Thrombo-endocarditis septica s. ulcerosa—Aschoff) In contradistinction to the superficial character of the lesions with simple acute thrombo-endocarditis, septic endocarditis shows deep inva- sion of valvular structures and of the free endocardium in a destructive, 472 DISEASES OF THE CIRCULATORY APPARATUS necrobiotic process; the formation of vegetations, abundant thrombotic deposit, and the presence of the virulent microorganism in great num- bers. Bacteremia is present and can be demonstrated by blood-cultural methods in most cases. Septic endocarditis should he considered to he of secondary origin in all cases; the exceptions are so rare as to require no consideration. There is no one pathogenic organism which causes the disease, it may follow in order of frequency streptococcus, pneumococcus, staphylococcus, influ- enza bacillus, gonococcus infection and in the chronic forms of the disease the streptococcus viridans (Schottmtiller, Rosenow, Libman) is now established as the leading factor, though there are many cases of chronic pneumococcus endocarditis and in all forms mixed infection may ulti- mately exist. Aschoff suspects that the viridans is a modified pneumo- coccus. The avenues of entrance of the infecting agent are numerous and often furnish surprises. The hlood is furnished with the specific organism from diseased ton- sils, the lung, the genitalia (women oftener than men), the puerperal uterus and adnexae, the hone marrow, the skin and from any source to which infection may he carried and from which the hlood current is infected. Insignificant (apparently) traumatism has in several of our cases led to malignant endocarditis. In two cases we found the passing of a urethral sound with slight bleeding followed by fatal endocarditis. In the cases following the unnoticed and insignificant primary infec- tion, the malignant nature of the endocarditis comes as a surprise. Often the primary disease is unheralded and overlooked—“In the endocarditis following the graver infections, one is dazed by the gravity of the pri- mary malady and fails to look for secondary and malignant disturb- ances” (Eisner). For prognostic purposes the frequency of septic endocarditis grafted or preceding valvular disease must be considered, the chronic lesion becomes an important and inviting factor. Goodhart showed that 61 of 69 cases presented old thickening of the valves, and mentions the occur- rence of malignant endocarditis with aneurismal disease. He further says: “Patients with chronic sclerotic valves are walking mushroom beds, in common times without spawn, but in periods of epidemics germs enter by various channels, which fertilize in these cases into ulcerative endo- carditis ; in others to suppurative processes.” Osier also mentions the frequency with which sclerotic disease of the aorta and valves is asso- ciated with malignant endocarditis. This is an exceedingly important fact for prognosis and with all primary infections, in the presence of chronic heart lesions it should not be ignored. Sir James Paget offered the data which proved the frequency with which changed valves suffer from acute disease. Of 84 cases of infectious endocarditis seen in St. ENDOCARDITIS 473 Bartholomew’s Hospital from January, 1890, to March, 1897, 51 were found in males, or 60.71 per cent, and 33 in females, or 39.29 per cent. The greatest number was found from the thirtieth to the fortieth years; most of the cases between twenty and forty. In these cases all but 10 were found either in patients suffering from old cardiac disease, or there was positive evidence of an infecting lesion. The tendency of old dis- eased valves in pneumonics to take on chronic malignant inflammation is surprising. It has been established experimentally by Wyssokovititch, Oliver and Rosenow that infectious material introduced in the blood stream attacks by preference the valves and endocardium which have been traumatically robbed of their protecting endothelium. To Heiberg belongs the credit of establishing the fact that in these cases, the vegetations on the valves were bacterially contaminated. The complication of malignant endo- carditis with septic conditions is fortunately comparatively rare, but with increased diagnostic skill it is more frequently found than formerly. Lenhartz found in the Hamburg Hospital 21 per cent of all general sepsis with endocarditis. Romberg reports in 33,539 of internal diseases during 8 years, 243 cases of sepsis with 42 malignant endocarditides. In 6,670 cases of inter- nal disease I found in my private and consultation practice 20 cases of malignant endocarditis including gonococcus and pneumococcus infec- tion. Of 7,770 cases of internal disease among whites admitted to Johns Hopkins Hospital (1902-1911) there were 1,317 diseases of the circulatory organs, among these endocarditis was diagnosticated in 38 males with 21 deaths, 55.3 per cent, and in 12 females, 33.3 per cent. How many of these were malignant is not stated. Endocarditis which is at first benign or appears to be so, may in the course of a few days end fatally with symptoms of malignant infection, while other cases which commenced with symptoms of malignancy may prove to be benign or non-septic. It is exceedingly difficult in practice to draw a line which shall sepa- rate the severer benign, from the malignant types, either by clinical study or blood cultural methods during long periods in individual cases. Re- peated negative cultures in cases of malignant endocarditis not infre- quently leave the clinician uncertain as to diagnosis and prognosis during long periods. In some of these cases the involvement of the right heart argues in favor of malignant infection. Bitten called attention to a variety of simple acute endocarditis associated with rheumatism which he styled “Non-septic Malignant Rheumatic Endocarditis,” in which many cases prove unusually severe and often fatal. This type of endo- carditis presents distinct features which must be considered separately and are not identical with those of malignant or septic endocarditis. In the favorable cases there is the same tendency to contraction and changes 474 DISEASES OF THE CIRCULATORY APPARATUS in the valves found in the less virulent forms. The right heart escapes involvement. There may be infarcts and metastases but these are never malignant, there is greater tendency to pericardial involvement, and recurrences of acute exacerbations in those who recover are frequent. There are no paralyses nor symptoms of embolism or purulent throm- boses. Death usually results with cerebral symptoms; albuminuria is transitory, the spleen is less enlarged than in malignant endocarditis. Tn 209 cases of septic endocarditis, Osier reports the tricuspid valve involved in 19 cases; the pulmonary in 15; the aortic and mitral together in 41; the aortic alone in 53, the mitral alone in 77, the heart wall in 33, and in 9 cases he found the right heart involved alone. These figures prove the involvement of the right heart out of all proportion to the left sided disease in the less malignant or other forms of secondary endo- carditis. The grave prognosis which is justified in all cases of malignant or septic endocarditis depends on the virulence of the primary infection, often mixed infection, the far-reaching local and general disturbances, the tendency of the diseased tissue to break down into minute particles which act as carriers of the infectious material to distant parts causing deep changes, hemorrhagic infarcts, mycotic aneurisms, and the further tendency to miliary abscesses, and purulent infarct in the various organs of the body, including the kidneys, spleen and heart. Ilarbitz and Lib- man claim that with the virulence of the infecting agent reduced, the local endocardial lesions may heal and cicatrice though the resulting damage to the valves and endocardium is greater than with single endo- carditis. We have no case to report, in which if such healing process did occur the life of the patient was saved in our practice; in no case in which the diagnosis of septic endocarditis was positively established clinically and bacteriologically has recovery followed—this is the expe- rience of nearly all clinicians. The following classification of Septic Endocarditis is most serviceable: I. Intermittent of pyemic form. II. Fulminating intermittent form. III. Typhoid form. IY. Cerebral form. V. Chronic Cardiac form. I. Intermittent or Pyemic Form.—Kirke and Traube dilated fully on the possibility of chills and fever and all of the symptoms of inter- mittent fever, with endocarditis. In these cases there is as a rule the history of preceding septic or purulent infection. Most cases are of streptococcus origin, show marked leukocytosis, the spleen is enlarged; with delirium, rapid pulse, moderate albuminuria, occasional hematuria, positive physical signs, early changes in the quality of the heart sounds and equally early embolic infarcts, cutaneous and deep, they die. ENDOCARDITIS 475 In some of these cases where there are preexisting heart lesions and consecutive murmurs, the character of these is often changed, and with this change there are transitory paralyses; sometimes evidences of em- bolic infarct in the skin, lung, brain, kidney or intestine, obstructive murmurs are often changed in character and occasionally become in- audible—for a time at least. Intermittent types with puerperal phlebitis run a short course to a fatal termination. Petechiae are often abundant. In these cases, as with all forms of septic endocarditis, the endocardium may be plastered ivith granulations and deeply ulcerated without causing murmurs or other physical signs until within a few hours or days of death, or these may never appear. The chronicity of some of these cases is strik- ing. Some persist with final irregular intermittent fever during from four to six months. Most die within four to six weeks. The diagnosis of inter- mittent malarial fever has often been made in cases seen before the days of blood cultural tests; at present these errors are rare. Quinin is entirely without influence on the course of the disease. Most patients die with symptoms of cerebral infarct. Among these intermittent cases, we recognize (a) pyemic or septic form, (b) erratic intermittent form, (c) late cardiac, intermittent form and (d) intermittent form with preexisting heart lesions. To the first of these, (a) Pyemic or septic form belong the cases of pyemia following puerperal fever. These patients carry pus foci (one or more), may be about for a time, but the course of the disease is usually short, always fatal. (b) The erratic intermittent form may have erratic chills, more or less continuous fever, the chills are very severe, the patient finally falls into a .typhoid condition with a zigzag temperature curve during which the chills observe no periodicity, there is delirium, coma and death. (c) The late cardiac intermittent form is characterized by absence of positive physical signs during considerable periods, unexplained chills, fever and pyemic symptoms persist during several weeks when the ob- jective features become clear and death follows. (d) Intermittent form with preexisting heart lesions includes those cases upon which a malignant infection is grafted. This group of cases bears the strongest resemblance to malaria. II. Fulminating Intermittent Type.—This type includes a number of cases which run a rapid course, terminating fatally in from ten to seven- teen days, occasionally sooner. Our series includes one case in which there was an infarct into the right eye causing complete blindness with characteristic quotidian fever and marked mitral systolic murmur. There were no petechiae. The source of infection remained undiscovered. The patient died before the 476 DISEASES OF THE CIRCULATORY APPARATUS end of the second week. Another death with fulminating intermittent symptoms was a child (obese) aged 12 years with violent chorea. There was, with the chills, hyperpyrexia, hematuria, cutaneous hemorrhages, delirium cordis, death in coma on the 13th day of the disease. Many of these cases show chronic endocardial lesions and they are likely to be of staphylococcus origin. III. Typhoid Form.—The typhoid forms may persist as such from the beginning, or the typhoid state may precede or follow any of the other types. Most cases belong to this form. Pure intermittent cases often merge into a typhoid state and die in that condition. Without chills, with more or less looseness of the bowels, enlargement of the spleen, leukocytosis (12,000-20,000), increasing anemia, albu- minuria, mental torpor with final cerebral infarct, in many, and with positive blood cultural finds, in almost all cases, these patients die in the course of from 6 to 12 weeks. IV. Cerebral Form.—Bramwell suggested the consideration of this type in his work on “Diseases of the Heart.” In all of these forms there is a strong tendency to coma and other cerebral symptoms as the disease advances. There is a strong resemblance to cerebrospinal meningitis or meningitis. In occasional cases there has been pneumococcus infection with pneumonia. In two cases, convulsions preceded death. One of our cases was associated with purulent pericarditis. In some cases the vegetations were so placed as not to give rise to murmurs. V. Chronic Cardiac Type.—This group includes all cases of chronic endocardial disease in which infection has led to mycotic endocarditis. The chronicity of these infections is characteristic with persisting bac- teremia, usually either pneumococcus or streptococcus viridans, erratic fever, anemia, leukocytosis, enlarged spleen, often joint pains, late in the course of the disease hematuria due to infarct, finally in most cases death from cerebral infarct or exhaustion. Septic Nephritis develops in most cases. In some there are mycotic aneurisms. Petechiae are found in almost all cases at some time during the long duration of the disease. Some of our patients have lived from seven to thirteen months. Death is usually caused by one or more good sized infarcts. I have found the association of infarcts into the brain, lung, spleen and kidney. Occa- sionally one or more of the multiple infarcts are found sterile. It may be assumed with considerable certainty, that the streptococcus viridans is the cause of most forms of chronic malignant endocarditis and that the prognosis is uniformly fatal. Gonococcus Endocarditis which should he included among the malig- nant types of endocarditis, offers only the most discouraging prognosis. It is fully considered in the chapter on gonococcemia. The unfavorable prognosis which I offer in all cases of septic and gonococcus endocarditis is justified by my experience in spite of those ENDOCARDITIS 477 cases in which from “time to time” greatly deformed cicatricial valves and remnants of infarct are found in patients who have died from other causes. Broadbent after mentioning these possibilities, concludes: “The number of authenticated cases recorded, however, in which recovery is reported to have taken place, is extremely limited, and it has not been my good fortune to see an undoubted case recover.

Chronic Endocarditis ( Cardiopathia chronica—Aschoff) General Considerations Included in the Prognosis of the Valvular Lesions of the Heart Acute or recurring endocarditis leads to cicatricial changes in the valves of the heart making one or more of these insufficient or stenosed, causing consecutive changes in the heart and distant organs, in accord- ance with the character of the lesion. There is, in truth, no true chronic endocarditis; the lesions 'produced are the results of gradual reparative changes which finally influence cardiac function and lead to the chronic endocardial and valvular defects above mentioned. 478 DISEASES OF THE CIRCULATORY APPARATUS The general acceptance of the term “Cardiopathia chronica ” offered by Aschoff is suggestive, and at the same time explanatory, and would do much to clear the horizon of the indefinite notions which are asso- ciated in the minds of many clinicians and students in connection with the misnomer “Chronic Endocarditis.” It is important to associate the chronic cardiopathies with two distinct primary processes, one inflammatory; the other degenerative. The first, or inflammatory process—is likely to attack the mitral valve by predilec- tion and the neighboring endocardium; the second, or degenerative proc- ess—(arteriosclerotic) selects the aortic valve and the surrounding tissue, and often the aorta itself, is part of an existing general arteriosclerosis and is often associated with coronary disease and myocardial fibrosis. With mitral lesions the degenerative or retrograde processes of the myocardium start in the coronary veins; with aortic disease, the lesions in the coronary arteries are likely to start the muscular insufficiency which is the threatening complication of all heart lesions. We are justi- fied in considering the faulty compensation of mitral disease as a “venous cirrhosis,” that of aortic disease as “purely arterial.” It is impossible to consider the diagnosis or prognosis of the car- diopathies (vascular lesions) without at once accenting the most impor- tant fact in cardiac pathology that in the majority of cases murmurs give hut little clue to existing dangers, that we find in the heart muscle “the hey to the pathology of the heart” (Stokes). Whatever the valvular lesion, “the symptoms depend mainly upon the strength or weakness, the irritability or paralysis, the normal or abnormal condition of the heart muscle.” It cannot be too often repeated that for safe prognosis we must assume that valvular lesions per se, have hut little influence on the gen- eral condition of the patient so long as the heart muscle remains healthy and sufficient. Gee’s aphorism teaches a valuable lesson. “A beginner can hear mur- murs and detect valvular disease, it requires long experience to appreciate nervous and muscular affections of the heart.” The seat and severity of the valvular defects naturally determine the secondary changes in the heart and other organs. (a) Hypertrophy.—The heart learns to accommodate itself to changed conditions, it is built to bear insult, it is the most tolerant of all the necessary organs of the body. With stenosis or insufficiency the heart undergoes such changes as are demanded by the increased tax made upon it. These must always be considered in connection with the separate valvular lesions. The gen- eral rule may be accepted without reservation, that whenever extra force and added energy are required, Nature makes a prompt attempt to de- velop the heart muscle to meet the demands; in other words the prognosis ENDOCARDITIS 479 is influenced by the growth of the muscle, its increased strength, indeed the separate fibers show characteristic change (Tangl). Only cases in which valvular lesions have existed a short time, fail to show some compensatory increase of strength. (Hypertrophy.) For prognosis, the important factors to be considered are, A. The reserve force of the heart. B. Compensatory hypertrophy. With the average defect, there is “a stasis behind the diseased valve and an anemia in front; the arteries consequently receive too little blood.” A. When called upon, the normal heart is competent to increase its force and strength of action thirteen fold (Zuntz). The reserve power of the heart makes it possible for the organ when disturbed by a valvular lesion to prevent circulatory disturbances and embarrassment so long as the body is kept at rest, or the organ is not overtaxed, and the distant organs receive their quantum of blood and the arteriovenous balance remains undisturbed. When extra work is thrown on the heart, the seat of any valvular lesion, the reserve is lowered. B. Compensatory hypertrophy becomes an immediate necessity to equalize the circulation and to prolong life. The demand which is made upon the heart to overcome an existing fault must determine the amount of necessary compensatory hypertrophy; under such conditions the prognosis is favorable in direct proportion to the ability of the heart muscle by increasing its volume, if conditions are continuous, to meet the added requirements. Under these conditions the prognosis is necessarily influenced by the ability of the patient to reduce the heart’s labor, in other words, the subject of valvular disease if he fails to give the heart muscle the sleep or rest to which it is entitled adds an element which reacts unfavorably, for the overtaxed and overtired muscle hypertrophies or compensates slower than does the muscle which has been subjected only to physiological strain. The prognosis is fur- ther influenced by the spontaneity of the response of the muscle to react to the added task; the nature of the valvular lesion, the method of its onset and the other factors which influence the outcome of all heart lesions. With aortic obstruction, the pressure within the left ventricle is increased during systole, the resistance offered by the narrowed or uneven ostium (valve) must be overcome and with a favorably reacting left ventricle, hypertrophy.leads to sufficient strength to overcome the obstruc- tion and the quantity of blood enters the aorta with sufficient force to meet all demands. These favorable conditions continue during many years in a large number of cases, are promptly influenced by conditions which increase obstruction in the periphery, by advancing degenerative 480 DISEASES OF THE CIRCULATORY APPARATUS changes in the arteries and increased blood pressure, by degeneration of the myocardium and other factors considered in connection with aortic obstruction and stenosis. The prompt hypertrophy of the left ventricle which follows aortic stenosis is not characteristic of the behavior of the left auricle when the mitral valve is stenosed. Here the auricle because of its anatomic struc- ture—poor muscular development—is less likely to hypertrophy, besides there are conditions in the pulmonary circuit which increase the amount of blood in the left auricle early during diastole, it is overtaxed during its systole, dilatation is invited and the extra work then thrown upon the right ventricle leads to its hypertrophy. With moderate, almost insignificant mitral stenosis, a limited hyper- trophy of the left auricle may prove sufficient to overcome the obstruc- tion and the circulation may continue undisturbed. With a high grade of mitral stenosis the pressure within the pul- monary circuit and in the left auricle is increased, and unless the hyper- trophy of the right ventricle continues sufficient, a break follows which influences prognosis unfavorably. This condition is separately consid- ered but it cannot be too often repeated that it is the leading danger of mitral stenosis. With valvular insufficiencies, physical and mechanical conditions are different than with the stenoses. In the former we are dealing with the regurgitation of blood into a cavity of the heart (with aortic disease into the left ventricle, with mitral insufficiency into the left auricle) and with both of these conditions the heart must of necessity contract with added strength to empty the respective cavity, but the cavity itself must accom- modate itself to hold the surplus or extra blood which it receives. More blood must be forced onward than the cavity normally receives during the period of rest. The result is change in the musculature to hold the extra blood and to force it onward. In favorable cases compensation is synonymous with the increase of strength of the muscle and a sufficient degree of physiologic dilatation. If dilatation is extreme, compensatory hypertrophy is less likely to prove prompt or satisfactory. Extreme pathologic dilatation always retards or lowers the chances of the growth of the muscle fibers to meet the demands. Regurgitant lesions (insufficiencies) tend to enlarge the openings situated behind the seat of the lesion. In most favorable cases in which the left side of the heart is enlarged, the right ventricle hypertrophies, thus maintaining the blood pressure in the pulmonary circuit. (b) Dilatation.—The physiologic widening of a cavity of the heart to accommodate itself to a surplus of blood is compensatory as already suggested and with increase of systolic force conditions continue favorable. If the heart muscle is weakened, the cavity is not entirely emptied/ ENDOCARDITIS 481 there is with increasing accumulation increase of dilatation and added demands are made upon the musculature of the organ. Unless this is successfully met, the stretching or dilatation of the heart may become extreme and evidences of such cardiac insufficiency are shown by added dyspnea and physical signs. With aortic insufficiency there are two sources from which blood enters the left ventricle during diastole: the regurgitation from the aorta because the cusps are not completely closed, and the normal supply from the left auricle. The heart muscle is called upon to exert itself to empty the ventricle during systole of the added quantity of blood, besides the content which is normally present ; sufficient force is demanded to send into the arterial tree all of the contained blood, besides contracting the ventricle to as nearly as possible its normal size. So long as this com- pensation continues undisturbed there is no fear of troublesome dilata- tion; when disturbed, the muscle lags behind, the blood accumulates in the ventricle, and pathologic dilatation without sufficient hypertrophy results. The dilatation of the left ventricle which results from mitral insuffi- ciency when associated with compensatory hypertrophy allows of suffi- cient discharge of blood into the aorta to compensate, without disturbing the circulatory balance. Conditions.—The conditions which bring about the compensation necessary to insure a favorable prognosis with valvular insufficiencies are therefore a sufficient or physiologic dilatation to allow of the regurgi- tated blood and muscular strength to empty the chamber completely of its contents. Blood Pressure.—When there is heightened blood pressure with in- sufficiency, dilatation becomes a serious condition and with the added systolic force needed to overcome the resistance in the periphery, there is, under failing conditions, an increase of residual blood in the ventricle, dilatation without hypertrophy and decompensation is the result. With increasing dilatation of the left ventricle, relative mitral insuf- ficiency may result; this in turn leads to dilatation of the left auricle and rise of pressure in the pulmonary circuit. The right ventricle is soon overtaxed in its attempt to overcome the resistance in the pulmonary artery, it dilates in unfavorable cases, tricuspid incompetence results with all of the secondary disturbances including dilatation of the right auricle and the evidences of stasis in the systemic veins and in the portal circuit. Under these conditions, the prognosis is exceedingly grave, the picture of circulatory embarrassment or break is complete. Simple uncomplicated hypertrophy of the left ventricle is exceedingly rare. When present, without other physical signs it is due to arterial- aortic disease and often to some one of the nephropathies. With persist- ently high blood pressure the latter may be strongly suspected. Under 482 DISEASES OF THE CIRCULATORY APPARATUS these conditions with proper care, life may be prolonged during many years. (See Myocarditis, also Nephritis.) (c) Decompensation.—The full compensation of a valvular defect may persist during many years and patients may die of intercurrent dis- ease. In most cases of (valvular) defects, added work thrown upon the heart is promptly followed, even in the average unfavorable case, by some subjective or objective symptom of revolt. In the majority of organic valvular lesions the heart tires ultimately and decompensation is more or less in evidence, in direct proportion to the weakness or lack of resistance of the myocardium. In many cases the patient is responsible for the unfavorable condi- tion because of overwork, excitement, excesses in diet, tobacco, coffee or alcohol, faulty living, exposure and a variety of depressing factors. Other agencies which invite decompensation are beyond the patient’s control; they include acute infections and many other diseases (metabolic) recur- ring endocarditis, worry, pregnancy, traumatism, etc. The myocardium always remains the prime factor in decompensation. With aortic disease and increase of degenerative changes in the arterial tree (arteriosclerosis), the myocardium suffers and symptoms are in- creased ; the forecast is made less favorable. Increase of valvular changes (contraction, insufficiency) necessarily adds to the work of the muscle and calls for further compensation. With valvular lesions the reserve force of the heart is reduced, the work which the organ accomplishes is often maximum or near the limit of its power, when this is exceeded, decompensation is likely to follow if the baneful factors persist. In practice, it is never safe to assume, in spite of statements by ex- cellent authorities to the contrary, that the hypertrophied heart is equal to the normal heart in its functional ability, that it is able to endure equal strain, that the reserve power of both is the same. The safest rule to accept for prognosis is that the heart which is changed to compensate for an existing fault is never as dependable as is the normal heart, that to overtax such an organ adds an element of danger which may lead to irreparable damage and when the insult is persistent decompensation must be expected. For the further study of hypertrophy, dilatation and de- compensation and degenerative changes in the myocardium, associated with valvular lesions, the reader is referred to the chapter on Myocarditis and to the following works: Krehl and Romberg, Dehio, Stokes, Aschoff and Tawara and Gerhardt (See References at end of chapter). It is impossible to separate the study of the myocardium from the valvular lesion in prognosis, the latter is of secondary importance, a fact to which the clinician must cling at all times. I have referred to increased blood pressure with arteriosclerosis as a cause of myocardial weakness and ultimate decompensation; in these ENDOCARDITIS 483 cases the prognosis, even with included aortic valvular lesions is best in syphilitic arteritis. Arteriosclerosis of the pulmonary artery or its branches with valvular lesions, aortic and mitral, in which the left ventricle is weakening, adds an element of danger and throws an added burden upon the right ventricle which may prove insufficient and lead to changes in the lung—bronchitis, pulmonary congestion or edema. Under these conditions the right ven- tricle is hypertrophied and insufficient. The prognosis of dilatation of the right ventricle under all conditions is more favorable than is that of the left ventricle. The former may de- velop suddenly and promptly disappear, the latter is usually threatening and serious. Hypertrophy of the right ventricle which continues during a consid- erable period is likely to prove permanent. On the other hand dilatation of the left ventricle may yield to treatment, there are many associated fac- tors to be considered in making the forecast. Acute, suddenly arising dilatation of the left ventricle is always of the gravest import. (d) Frequency of Valvular Lesions.—From three to five per cent of all internal diseases are due to chronic valvular lesions. Gerhardt gathered the following statistics showing the frequency of valvular dis- ease. He found that in hospital practice from two to five per cent of all internal diseases were due to valvular anomalies. Leuch claimed 2.1 per cent, Schmidt 3.3 per cent, Guttman 5 per cent, Duchek 2.3 per cent, my own statistics 5 per cent (private practice). In private practice the number of heart lesions are greater than in most general hospitals. Ger- hardt found that of 1,200 patients seen in private and consultation prac- tice, 289 complained of heart symptoms with 65 valvular lesions, 115 myocardial disturbances, 109 neuroses. Of those complaining of heart symptoms 25 per cent have valvular lesions. (e) Sex.—Sexes run nearly evenly with a small per cent in favor of the female. The prognosis of heart lesions, i. e., valvular defects is more favor- able in women than in men. This is true of all organic diseases of the heart, including its arterial supply. Hoffman’s statistics gathered at Johns Hopkins Hospital (1902-1911) show that of all forms of endocarditis 55.3 per cent of white males and only 33.3 per cent of white women died. (f) Heredity and Family History.—Heredity has a powerful influ- ence on the prognosis of the chronic cardiopathies; this is particularly true of lesions of the aortic valve. Schott found 26 per cent of all valvu- lar lesions with a family tendency. The prognosis is always less favor- able with a clear family history of heart disease. To this fact I refer in connection with angina pectoris. With an aortic valvular lesion, the history of anginous attacks and an 484 DISEASES OF THE CIRCULATORY APPARATUS unfavorable family history the prognosis is correspondingly grave. Eich- horst and Mohr offer data which show positive hereditary tendency to valvular lesions in some families. (g) Age.-—Age is an important factor in the prognosis of chronic valvular lesions. Young children with permanent valvular defects offer an unfavor- able prognosis. During the active years of life the prognosis of the lesions which result from inflammatory disease (mitral usually) is relatively favorable. The degenerative (aortic lesions) valvular lesions, however, offer an un- certain and usually an unfavorable forecast. Valvular lesions during old age are likely to be associated with such other senile defects as justify only clouded prognoses. With such patients arteriosclerosis is the most frequent accompaniment; the prognosis natu- rally depends upon the rate of its progression. In a large percentage of these cases the advance of the sclerosis is slow and not infrequently the process remains stationary during a number of years. Compensation for valvular faults in advanced life is often surprisingly prompt. The heart instead of undergoing atrophy is stimulated and enlarges. Leyden says, “the heart is the only organ the size of which increases during old age.” He claims that the heart of the youth is “more likely to exhaust itself than is that of the older individual.” (h) Occupation and Social Conditions.—The influence of occupa- tion and social status on the course of valvular lesions is of paramount importance. From the data given in the preceding paragraphs it is at once evident that occupations which require considerable physical effort, if continued, are less favorable than are those in which the patient is kept comparatively quiet. Valvular diseases {usually aortic), in those who are subjected to men- tal strain, worry, hurry and excitement are not likely to hold their com- pensation. Myocardial degeneration with aortic and coronary lesions and interstitial nephritis (sclerotic) are the complications which lead to death, The factors included in the stress of modern life lead many active busi- ness and professional men to an early fall in the presence of a chronic cardiopathy. With mitral stenosis and aortic insufficiency the prognosis is often favorably influenced by occupation which conserves the patient’s energies and strength and does not add a burden to the overworked heart. The ability of the patient to control his movements, to take advan- tage of favorable climatic influences guided by intelligence and sobriety become enormous factors in his favor. Though valvular lesions are usually incurable, patients are often re- sponsive to intelligent supervision, and if their social status permits of ENDOCARDITIS 485 the control indicated in the individual case with a healthy suggestion and sufficient optimism life is often made comfortable during many years. (i) The Influence of Intercurrent Diseases.—Infections.—In spite of serious valvular lesions, the heart, under extra strain, in the presence of added disease, which in the perfectly healthy subject requires the assist- ance of a resistant organ, does its work satisfactorily and in the end the disease terminates favorably. The heart under such conditions bears the burden during the acute period of the complication, hut there may be and often is a revolt during convalescence in some cases; with the disappear- ance of the acute symptoms the myocardium may be found weakened or degeneration may follow and insidiously undermine its strength. On the other hand, the heart may not be unfavorably affected, and after the added tax, the previous lesion is found unchanged. Hearts, the seat of organic lesions with kidney complication, do not hear added infection well; this is especially true during the active years of life. Old subjects with organic lesions of the valves, even aortic, bear acute non-malignant exacerbations fairly well provided the myocardium func- tionates normally; this is not true of aortic insufficiency or marked mitral stenosis. The heart, the seat of a valvular defect with chronic infection super- added, bears the strain surprisingly well during weeks and months in the presence of high fever, rapid pulse and wasting disease. This is demon- strated by the chronicity of many infections of which tuberculosis, pyemia and viridans streptococcemia are examples. Some infections promptly establish cardiac tolerance, which for prognosis is of great importance, while with other toxic conditions the heart muscle seems without resist- ance and promptly wilts. In the consideration of the infectious diseases we considered the chronic lesions which they complicate. A few general conclusions are here added to make reference easy and prompt. (The reader is also re- ferred to the separate infections and their complications). Pneumonia.—With aortic lesions and general arteriosclerosis in old individuals the prognosis in the presence of pneumococcemia is unfavor- able. All cases of pneumonia in subjects with valvular disease are grave, recovery is not impossible and takes place in a good number of cases. Polly and Blumstein report 1,048 pneumonics of which 17 had valvu- lar lesions; of these 5 died—29.4 per cent against the average mortality of 21.6 per cent. A number of our cases made uninterrupted recoveries from pneumonia -with chronic valvular defects of all kinds. The recovery is slow, the course of the disease is likely to be atypical, and the disease usually terminates by lysis. Influenza does not influence valvular lesions favorably. If pneumonia develops, the prognosis becomes grave. The period of convalescence from 486 DISEASES OF THE CIRCULATORY APPARATUS uncomplicated influenza in the subjects of valvular disease is slow, and the heart continues irritable during long periods, the myocardium is often weakened and existing compensation is unfavorably influenced. In influenza and pneumonia the prognosis depends largely on the de- gree of existing compensation and the general condition. Erysipelas.—My experience with erysipelatous infection and chronic cardiopathies has been limited. Gerhardt reports that two of his patients made prompt recoveries. In both the lesions were old and well compensated with mitral stenosis and moderate aortic insufficiency. With decompensation and erysipelas the prognosis is unfavorable. In such patients, as Gerhardt says, the erysipelatous inflammation is likely to attack the edematous extremities. Bronchitis involving the smaller tubes with advanced valvular disease may lead to sudden death or to serious symptoms which often continue threatening during many days. Bronchiolitis and bronchopneumonia in young subjects and in the aged are always serious and are among the most frequent causes of death of old subjects in hospitals. Recurring tonsillitis in young subjects is a frequent cause of acute ex- acerbations of chronic cardiopathies and increases all factors which lead to greater permanent damage than previously existed. Malignant Endocarditis.—The dangers of malignant endocarditis as a complication of chronic valvular disease has been separately consid- ered in this chapter. (See Septic or Malignant Endocarditis.) (j) The Influence of Marriage and Pregnancy on Valvular Disease. —My personal experience with the results of pregnancy on the subjects of valvular disease has been surprisingly favorable. In an active prac- tice of over thirty-seven years I recall but three deaths of patients with valvular disease during pregnancy, or as the result of childbirth. There is, however, a great difference of opinion in the profession as to the influence of marriage and pregnancy in women with chronic valvular lesions and as to the advisability of recommending marriage to them. The variation in the statistics of observers in the mortality of heart lesions during labor is shown by the following percentages of death: Mueller 3.0 per cent. Gusserow 6.0 “ “ Wiesenschal 12.5 “ u Lewoff 12.0 “ 11 Jess 31.5 “ “ Guerard 34.0 u a Schalyer 48.0 “ “ Wessner 49.3 “ “ Von Leyden 55.0 “ u Lublinsky 60.0 “ “ MacDonald 61.0 “ “ ENDOCARDITIS 487 Fellner’s statistics prove two important prognostic facts. One, that the percentage of reported cases was much too low and did not include many with organic diseases of the heart, which were discovered on careful routine examination; (it was found that six of seven cases of compen- sated heart diseases were escaping the attention of the examiners at the clinics) and the other was the cautious treatment and watching of these cases which lead to the advice at the Schauta Clinic to “terminate preg- nancy in cases of mitral stenosis as soon as the slightest signs of broken compensation appear” or whenever evidences of danger were present in previous pregnancies. (Hirschfelder.) There was but one death in twenty-one pregnancies complicated with valvular lesions at the Schauta Clinic. In ten years Fellner found 81 cases, in which three mothers were lost and 26 children. The highest mortality was found in mitral uncompensated stenosis among the newborn. Seventeen mothers with one death, ten children died. Among 900 pregnant women there were twenty with valvular lesions, one death and five children lost. The one death was in a case of mitral stenosis uncomplicated. Ilirschfelder says: “These statistics from unselected cases are much more favorable than the previous reports would indicate, and are in accordance with the con- clusions of Hicks and French that few women with heart disease are sterile, that they are not particularly liable to abort and that most of them bear children well.” Occasionally sudden death takes place before labor during advanced pregnancy, of chronic mitral insufficiency, broken compensation and renal invasion. I have seen cases in which, without the approach of labor, and evidently no factor added save the changes which accompany preg- nancy, after a few days of increased dyspnea, death followed suddenly from acute dilatation. Relative tricuspid insufficiency persisting during pregnancy or organic insufficiency with increasing dyspnea and cyanosis, enlargement of the liver, with or without edema of the extremities is a serious condition, and may in the pregnant woman lead to death at the time of labor or before. Much will depend on the care of these cases. I have recently seen such a case which we referred to a young and conscientious obstetrician, in which all symptoms seemed unfavorable, but which with persistent atten- tion to detail, in a appointed hospital was carried safely through labor and is still living. The persistence during pregnancy or labor of the usual severe symp- toms of broken compensation with any chronic valvular lesion is of serious import. With dyspnea, orthopnea, cyanosis and albuminuria and an uncompen- sated valvular lesion, ivomen rarely live long beyond labor. Hirschfelder says, “in from 25 to 40 per cent of patients with severe heart lesions the pregnancy does not reach term, but premature labor occurs spontaneously 488 DISEASES OF THE CIRCULATORY APPARATUS owing to partial asphyxia of the fetus.” These statistics, so far as the premature expulsion of the fetus are concerned, are much higher than any which we have been able to gather in our own practice or from our colleagues. The statistics of mitral stenosis give a higher mortality for mother and child and approach those of Ilirschfelder. Abortion is also more frequent in these. Fellner found 2G per cent of stillbirths among women with valvular lesions. Occasionally aortic lesions which are very rare during the child bearing period cause sudden death. Mackenzie holds that dilatation during pregnancy affects the right heart, and that a woman otherwise normal may develop a definite tricuspid insufficiency as shown by the presence of a systolic murmur in the tricus- pid area and venous pulse. This murmur may come and go, returning under varying conditions of the patient, it is therefore a relative insuffi- ciency. These hearts may break compensation and pulmonary edema develops. This is most likely to happen with added mitral stenosis and pulmonary engorgement preceding. Slemon and Goldsborough and Williams and Slemon have studied the influence of labor on the heart and they report that the act of labor itself does not add to the strain of the heart unfavorably. This is certainly true of a heart with a good myocardium. With marked or limited myocardial degeneration of whatever nature, with or without valvular lesions the added strain of pregnancy and labor is likely to lead to a very serious condition in which the life of both the mother and the fetus are jeopardized. If there is any one condition which justifies the interdiction of mar- riage it is valvular disease with persistent myocardial insufficiency. Marriage is not without its dangers to the woman who has a valvular defect. The question which presents to the physician—whether marriage is to he sanctioned—can only he answered by a painstaking survey of the individual case. In the presence of a well compensated heart, with mitral insufficiency or moderate aortic obstruction or a combination of valvular lesions which are ivell borne, in the absence of other defects, with a normal urine and favorable surroundings, marriage may be sanctioned. With aortic insufficiency and with mitral stenosis both marked, with consecutive changes, there is just reason for hesitation. Marked hyper- trophy and moderate dilatation with the former, in our opinion is suffi- cient to interdict marriage. Moderate mitral stenosis with compensation may under favorable conditions justify marriage, but an advanced degree of stenosis with secondary changes in the right heart does not justify the clinician, who must assume the enormous responsibility of deciding the question to recommend marriage. The same holds true of the advisa- bility of the marriage of a man who has similar valvular defects and sec- ondary changes. ENDOCARDITIS 489 The social status with all that is included in environment becomes an important factor in deciding upon the future life of the woman as well as of the man in the presence of valvular and myocardial disease. (k) Influence of the Usual Complicating Diseases on the Course of the Chronic Cardiopathies.—Pericarditis is separately considered (See Pericarditis) as a frequent complication of all forms of endocarditis. There are occasionally acute forms of pericarditis which complicate chronic valvular lesions and arise suddenly; many of these are of the dry type (pericarditis sicca), others accompany acute exacerbations of rheumatic origin. Unless there is considerable effusion or purulent peri- carditis, the addition of dry pericarditis does not affect the chronic cardi- opathy unfavorably. With added septic infection and pericardial invasion the prognosis is always had. Diseases of the Respiratory Organs.—Persistent disturbances— bronchitis and pulmonary stasis are found in the more serious cases and terminal stages of valvular disease, they influence prognosis unfavorably. Degenerative changes in the endocardium (arteriosclerosis) myocar- dial fibrosis and chronic bronchitis proves a complex which is rebellious to treatment, is occasionally favorably influenced by climatic change, but allows of only the gravest forecast. Cardiac Asthma and Dyspnea.—Por prognosis, in the presence of a valvular lesion, a prompt test of the resistance of the heart can be made by cautiously leading the patient to exercise and noting the result on res- piration and pulse. Dyspnea on slight exertion is evidence of insuffi- ciency and gives the safest indications for treatment and prognosis which we possess. Relative muscular insufficiencies are thereby developed which are also significant. Severe dyspnea and cardiac asthma appear threatening at times, but under treatment in many instances disappear even in the presence of drop- sies and other symptoms of insufficiency. The prognosis should in the average case be made only after the trial of rational treatment and rest. In these cases, particularly with mitral insufficiency, results are surpris- ing and improvement is held during long periods. With hydrothorax, hydropericardium, dilated left ventricle and an insufficient right heart and general anasarca the prognosis is grave. With aortic lesions and cardiac asthma and dsypnea, the prognosis is less favorable than with mitral insufficiency. With aortic lesions and coronary sclerosis, cardiac asthma, with or without stenocardia, the chances for the patient to lift himself out of the attack are much reduced, though the heart may mend during considerable periods under such unfavorable conditions. Dyspnea and cardiac asthma depending on auricular insufficiency are more favorable than are similar symptoms with ventricular disease (dila- tation, etc.). 490 DISEASES OF TIIE CIRCULATORY APPARATUS Cardiac asthma with pulmonary edema when a sudden complication makes the presage unfavorable in almost all cases. Bkown Induration of the Lung.—Brown induration of the lung is always proof of long continued insufficiency. The weakness and dilata- tion of the left ventricle with bronchiolitis and the characteristic “cells of heart failure” in the sputum must lead to a guarded, usually unfavor- able prognosis. In these cases of bronchitis due to brown induration, and congestion or edema, the sputum is rich in albumin in contradistinction to the sputum of uncomplicated bronchitis. (The Fr. v. Mueller test aids in diagnosis and prognosis. Add to the sputum three times its volume of a three per cent acetic acid solution, shake thoroughly and filter; then add a few drops of ferrocyanid of potassium solution when the albumin content will be precipitated). Pulmonary edema due to dilatation of the left ventricle is more serious than stasis caused by right heart change. The latter is often of short dura- tion, the former in the presence of marked valvular insufficiencies and organic muscle change frequently leads to prompt death. The significance of hemoptysis depends entirely upon its cause. There are cases of moderate stenosis of the mitral valve in which hemoptysis continues during long periods without seeming to have any unfavorable influence. The bronchial or pulmonary hemorrhages are not as a rule threatening or profuse. Aortic lesions rarely lead to hemoptysis. In occasional cases of mitral stenosis, tuberculosis may prove to be the cause of hemoptysis. With congenital or acquired pulmonary stenosis, tuberculosis is fre- quent and the bleeding is a symptom of ulcerative or disorganizing change. Embolic infarct may be a cause of hemoptysis; when present with the exacerbation of a chronic endocarditis it is of malignant or septic origin and offers an unfavorable prognosis. Infarcts also accompany non-malig- nant valvular lesions and are always to be interpreted as being of serious moment. They are found in the lungs of patients who during considerable periods had broken compensation. Pulmonary infarcts usually lead to death within a limited period because they are in the majority of cases coincident with fully developed cardiac asthenia; an occasional infarct may not be followed by death, recovery may slowly follow and compensa- tion restored. Ginsburg presents interesting data. Of 250 autopsies in subjects who died of heart diseases there were 197 with valvular lesions; of these 85, 34 per cent showed emboli, 35.4 per cent had endocarditis of the left ventricle, 47.1 per cent of both ventricles, 29.4 per cent myo- carditis, 20 per cent dilatation and hypertrophy. Infarcts were found in the kidney in 62 cases, spleen 23, brain 15, lungs 14, intestinal mucosa 3, tibial, bronchial, brachial, coronary arteries each once and once each in the pia mater and uterus. Tuberculosis.—The association of tuberculosis and chronic valvular ENDOCARDITIS 491 lesions is considered in the chapter on tuberculosis (Cardiovascular culosis). Congenital pulmonary stenosis, mitral and aortic stenosis are often found with lung tuberculosis. Pleurisy.—Pleurisy may complicate valvular lesions, is often present with pulmonary infarct; if the effusion is small it does not influence the case unfavorably, if large it adds to the danger. Most pleural accumulations are non-inflammatory and are the direct result of cardiac insufficiency. (See Hydrothorax and the separate Valvu- lar Lesions.) (l) Blood.—When with advanced valvular lesions there is polycy- themia, it is an indication of insufficient heart strength and imperfect oxygenation. The loss of the watery element of the blood with extreme concentration in the terminal stages with dropsies is unfavorable and death under these conditions is not long postponed. With insufficiency of the right heart, cyanosis and polycythemia are often long tolerated and may yield to treatment. Increased viscosity of the blood is found in cyanosed patients and with extreme insufficiency—evidence of extreme danger. Various grades of anemia are found during the course of most valvu- lar lesions at different times, their prognostic significance depends upon the underlying condition rather than on the blood state. (m) Skin.—The skin shows changes which the experienced clinician interprets at a glance in many cases. The mottling and cyanosis, the cold extremities, the clubbed fingers and the evidences of chronic stasis with dermatitis or eczema are among these. (n) Nephritis.—True nephritis is only rarely an accompaniment of valvular disease. Chronic congested or cyanosed kidney including the accompanying albuminuria is a frequent expression of stasis and muscu- lar insufficiency. Infarcts into the Icidney are frequent with malignant and benign endocarditis. These give rise to so-called hemorrhagic nephritis. Chronic Interstitial Nephritis or the arteriosclerotic Icidney (See Chronic Interstitial Nephritis) with aortic lesions and general arterioscle- rosis deserve separate consideration and is part of a general process. When present with any form of valvular disease it adds to the dangers and influ- ences the course of the disease. (o) Liver.—Enlargement of the liver, acute or chronic, with valvular disease is a frequent complication, and is often an expression of insuffi- ciency of the right ventricle, is present in mitral disease with decompen- sation. Advanced stasis, the cause of liver enlargement in these cases leads to ascites, gastritis, enlarged spleen and many depleting intestinal symptoms. Organic change may lead to cirrhosis. (See Pericardial Pseudocirrhosis). Tricuspid insufficiency is a frequent cause of liver enlargement. Jaun- 492 DISEASES OF THE CIRCULATORY APPARATUS dice, when persistent or with cyanosis and other symptoms of stasis has in our experience proved to be of serious significance. It is not infrequent in cases of malignant endocarditis, grafted on chronic valvular lesions. Gall-stone colic may lead to sudden death in the presence of a thin heart muscle and valvular disease. We include one such case in which an obese woman with chronic mitral obstruction and fatty heart died dur- ing a gall-stone colic of rupture of the left ventricle. Frequent exacerbations of cholangitis and cholecystitis with gall- stone disease and valvular defects may lead to acute infection of the dis- eased endocardium, malignant endocarditis and death. Naunyn, Lenhartz and Eisner call attention to these cases. (p) Nervous System.—Psychic Disturbances.—Psychoses are relatively frequent with valvular lesions. Kraepelin believes that venous stasis accounts for most of these. Romberg found thirteen psychoses among 1,200 heart diseases, mainly of the depressive forms. Complications.—Epilepsy, hysteria, neurasthenia, persistent insomnia, somnolence, involvement of the respiratory center, Cheyne-Stokes breath- ing, persistent headaches, vertigo, chorea, and anomalous sweating are among the many complications referable to the nervous system. All of these conditions, particularly the psychoses, epilepsy, hysteria and neu- rasthenia, may develop without in any way influencing the valvular lesions; the psychoses themselves offer a less favorable prognosis with chronic valvular lesions than do those which complicate rheumatic acute endocarditis. (q) Dropsies.—To these the author has referred in considering the prognostic value of other symptoms and in connection with the dangers of the separate valvular lesions. (r) Pulse.—In considering the pulse we are again reminded of the fact that whatever prognostic data we obtain from its study must he furnished by the myocardium, upon its efficiency, its ability to overcome and accommodate itself to existing faults, clearly demonstrated by mod- ern methods of examination depends the future of the patient. The pulse is fully considered in connection with the lesions of the individual valves and with myocarditis. (s) Blood Pressure.—(See Consideration of the Lesions of the Indi- vidual Valves.) (t) Rontgen Examination.—The use of the x-ray for purposes of diagnosis and prognosis has become invaluable in practice. By the aid of the fluoroscope and the Rontgen photogram we are at once, in most cases, given a view of the size of the heart, more particularly the left ventricle and the right auricle and the relation of the organ to its surroundings. These results can he corroborated by the orthodiagram. Repeated x-ray examinations permit of the close observation of the effect of treatment and its influence on the organ. The changes which follow in the blood ENDOCARDITIS 493 vessels closely related to the heart and in distant organs which influence the course of valvular lesions are easily followed. For a full study of this subject the reader is referred to the splendid works of Groedel and Schwarz. To gain valuable data for prognosis, the examinations should always be made by those who devote themselves to this special work. In- terpretation demands experience. (u) Sudden Death and Valvular Anomalies.—Sudden death is an exceedingly rare occurrence with chronic valvular disease of the heart. There are warnings in almost all cases given by the failing muscle and the increase of secondary manifestations. The heart may occasionally, as in aortic insufficiency with dilatation and faulty compensation, stop with- out warning, but such sudden end is exceptional. With an unchanged or compensated muscle the heart will continue the struggle; under such conditions there is sufficient reserve force to prevent stasis and sudden acute dilatation. When there is increasing secondary engorgement and the reserve is insufficient, the abundant symp- toms and physical signs give timely warnings. Aortic lesions associated with coronary disease (angina pectoris) may lead to sudden death. Such patients stand on the edge of a precipice, they may fall at any time. Under control, women particularly, may live dur- ing long periods. Less than two per cent of mitral lesions lead to sudden death. (Leyden.) Obese patients—large portly men—with small fatty hearts, weak and rapid pulse, with arteriosclerosis and aortic stenosis (degenerative) are always threatened and often die suddenly. (v) Anatomic Cure of Valvular Lesions.—Unquestionably there are cases of acute endocarditis which are followed by well marked physical signs of valvular deformity, murmurs, and muscular changes, in which all physical and subjective symptoms disappear and the patients continue well. Post mortem examinations prove the possibility of the complete ana- tomic cure of valvular lesions. Mitral insufficiencies of organic origin have disappeared, never to recur. (Amsler, Leyden.) The clinician should assure himself that he is not dealing with relative insufficiencies in these cases. (w) The Influence of Treatment on Prognosis.—With full compen- sation, well regulated life, quiet temperament and a healthy suggestion which allows the heart to remain light while the brain is agreeably occu- pied; many patients with valvular lesions live in comfort during many years. The psychic element in all forms of heart lesions is overpowering, it influences longevity materially for good or ill. The physician is largely responsible through his personality and included tact for the creation of a healthy optimism which means so much to the patient. 494 DISEASES OF THE CIRCULATORY APPARATUS The influence of rest, well chosen and properly directed hatlis and exercises is often paramount in the presence of the waning heart muscle. The reaction of 'properly selected cases to digitalis is of enormous value in piercing the future of the cardiopath. Prompt reaction to digitalis in the presence of mitral disease is always encouraging. The prognosis is best in those cases in which the favorable effect of the remedy continues during a comparatively long period. When the effect is evanescent or of short duration, and the remedy is necessarily required at correspondingly short intervals there is danger that it may soon fail to produce the satis- factory strengthening of systole. Naturally the prognosis depends upon the ability of the therapeutist to administer the remedy secundum artem and upon the continuous supervision of the life of his patient. There are cases in which dropsies with incomplete compensation and threatening symptoms due to distant stasis yield and under rational treat- ment such patients may live during many years. The specific (syphilitic) lesions of the valves, usually the aortic, offer favorable prognosis in direct proportion to the improvement which follows modern treatment. (See Cardiac Syphilis.) The prognosis of heart le- sions has been enormously influenced by the indications for treatment sug- gested by the Wassermann reaction of the blood in the larger number of aortic lesions. (x) The Influence of Physical Signs.—The prognostic significance of physical signs is readily shown by the relative dangers of the different valvular lesions to which reference is made in considering these. The fact which should he forcibly impressed upon the beginner is that loudness of the murmur as a rule, hears no relation to the gravity of the lesion. It is often more favorable than soft or low murmurs. Systolic murmurs are more favorable than are the diastolic; in many cases they finally prove to be of functional origin (hemic, etc.). Naturally in offering the forecast, attention must be given to all of the many details considered in this chapter. Diastolic and presystolic murmurs are almost always of organic origin and demand serious thought and attention for prognosis. The abnormalities of rhythm—intermission and arliythmia—are con- sidered with the separate lesions and in the chapter on myocarditis. Delirious hearts (delirium cordis) are often well borne. They always add to the danger. When due to auricular fibrillation the prognosis is much better than with the ventricular disturbance; alternating pulse with any form of arliythmia or myocardial disturbance is unfavorable. (y) The Fate of the Chronic Cardiopathies.—Romberg found that the duration of the period of compensation averaged seven years. One- third of his cases went beyond that time without a break, and the maxi- mum period was found to be thirty-eight years; one-third of his cases re- mained without compensation from the beginning. ENDOCARDITIS 495 Gerhardt reports 300 cases of which 123 allowed positive conclusions: No. OF Duration of Compensation. Cases. 0- 5 years 37 6-10 years 33 11-20 years 30 21-30 years 9 31-40 years 12 41-44 years 2 The average was twelve years. The average duration of primary compensation in man is nine years, in woman ten years (Gerhardt). Localization of Valvular Lesions and their Forms The prognosis of chronic valvular disease largely depends upon the valve affected and the degree of resulting deformity. There is an enor- mous difference as has already been hinted in the dangers of mitral and aortic disease. Most authorities claim that aortic insufficiency is the most serious of all valvular lesions, including Osier, while a large number in- cluding Colbeck and Gerliardt claim that mitral stenosis is the most serious. Osier calls attention to the fact that, in women particularly, mitral stenosis is almost on a level with mitral insufficiency. Uncompli- cated aortic stenosis is the most favorable of all lesions, mitral insufficiency when well compensated offers a good prognosis. Aortic stenosis and mitral insufficiency are the most frequent valvular lesions after the thirtieth year. Mitral Insufficiency.—Over 50 per cent of all valvular lesions are due to mitral insufficiency. Mitral insufficiencies both alone and asso- ciated with other valvular lesions were present in 64 per cent of the Johns Hopkins Hospital cases, occurring alone in 29 per cent. Mitral insufficiency offers greater encouragement for complete anatomic cure and insures longer periods of compensation than does any other valvular lesion. With mitral insufficiency the following facts require consideration in offering a forecast besides those included in “General Considerations of the Valvular Lesions.” The cause of the lesion hears directly on prognosis. Rheumatism, chorea and scarlet fever justify the most hopeful outlook, because in the large proportion of cases there is no danger of exacerbation after reason- able immunity. Full compensation may never be disturbed, the future is often in the hands of the patient. Reasonable care insures safety in most cases. Mitral regurgitant murmurs due to chorea disappear after a few years. Sir Andrew Clark taught that they never were found after ten years. Mitral insufficiency is more amenable to treatment than any of the other valvular lesions. 496 DISEASES OF THE CIRCULATORY APPARATUS Dropsies which have existed only a short time with mitral insufficiency and without extreme loss of compensation often yield, and life may con- tinue many years. Extensive dropsies always add to cardiac embarrass- ment. Mitral insufficiency with long continued dropsy and evidences of broken compensation justify a guarded prognosis, the result of treatment must clear the horizon. Associated conditions bear directly on the out- look. With mitral insufficiency, “arteriosclerosis-insuffisance mitral-arte- rielle” of Iluchard—which is usually caused by gout, lead poisoning, or dietetic excesses, is frequently associated with renal disease,” and dyspnea is often severe and prognosis grave (Moon). With arteriosclerotic changes in the endocardium, there is tendency to progression and a less favorable outlook than with the “endocarditic form of valvular disease” Blood Pkessure.—Much depends on the resistance in the peripheral vessels. With abnormally heightened blood pressure the force of the regurgitation is increased, the backward pressure in the left auricle is augmented and an added demand is made on the right ventricle. Pulse Pressure (amplitude) is far more reliable than simple systolic blood pressure, for it gives an index of the burden which the heart is carry- ing. Undue frequency of the pulse with arhythmia perpetua due to auric- ular fibrillation need not always to be seriously interpreted. Digitalis will usually control the symptom. The perpetual arhythmia is less significant with mitral disease than with aortic. When in mitral insufficiency the heart which has been regular and its frequency within reasonable limits suddenly develops perpetual arhythmia it signifies increased weakness or dilatation of the left auricle and nothing more, but this fact must be added to the many details of the individual case if safe conclusions for prognosis are to be reached. Decided fall of blood pressure (hypotension) is unfavorable; it usu- ally signifies myocardial insufficiency. In all cases of mitral insufficiency physical signs should be watched for evidences of dilatation (increase in the transverse diameter) and evidences of stasis. The pulse is increased in size so long as compensation is sufficient, therefore a favorable sign. A small, thin, rapid pulse (umitralized pulse”) is proof of insufficient muscle strength. Pulmonary stasis and dyspnea go hand in hand; they indicate broken compensation. The strength of the left ventricle is of greater prognostic value in considering pulmonary stasis than is that of the right ventricle, for the former when acting well empties its own cavity of more blood than the right ventricle pumps into the pulmonary artery. There is ENDOCARDITIS 497 therefore a surplus of blood leaving the lungs under these conditions until the congestion is relieved. Hirschfelder says, “The whole condition may be summed up by the statement that a weakly acting left ventricle overfills the lungs with blood, while a strongly acting left ventricle bails them out. The whole of pulmonary engorgement is, as rightly claimed by V. Basch, a problem not of the right ventricle, but of the left.” Accentuation of the second pulmonic sound indicates involvement of the pulmonary circuit, this is not always significant. Mitral insufficiency may continue during years with an accented second pulmonic sound with good compensation without the addition of serious complications, The following summary may be safely followed: The favorable cases of mitral insufficiency are those in which com- pensation is sufficient; there is no dyspnea, no dropsies, the pulse is full, not excessively rapid, pulse pressure within normal limits, general con- dition satisfactory, urine free and non-albuminous, no enlargement of liver or spleen, and physical signs correspondingly encouraging, includ- ing moderate enlargement of the left and right sides of the heart; the second pulmonic moderately accented. The unfavorable cases are those in which the leakage is large, pulse is “mitralized”—weak, rapid, irregular, pulse pressure and blood pres- sure are reduced, heart cavities dilated, the right ventricle particularly, and the left insufficiently hypertrophied; the murmur obliterates the first sound of the heart entirely, the second pulmonic is greatly accented, the radial artery cannot be felt between the beats, there is continuous dyspnea and evidences of pulmonic and systemic engorgement.” Lung complications—pulmonary edema, pleurisy with effusion add to the work of the heart, overtax the rigid ventricle and cloud the prog- nosis. For the significance of embolic infarct, thrombosis, pericarditis and other complications, the reader is referred to the General Considera- tions, etc., of Valvular Lesions. Mitral Stenosis.—The outlook is influenced by the degree of mitral obstruction. Moderate stenosis is tolerated during many years, in fact during a long and comfortable life without causing subjective symptoms and is often accidentally discovered post mortem. Extreme stenosis leads to secondary changes because insufficient blood is forced into the left ventricle, the arterial tree is correspondingly empty, there is stasis in the left auricle, the pulmonary circuit, and the right ventricle is called upon to overcome the obstruction by added muscular force, hypertrophy and dilatation result. When the right ventricle is overtired and overtaxed, dilatation increases, the reserve muscular force is exhausted and decompensation with all of its complications is in evidence. 498 DISEASES OF THE CIRCULATORY APPARATUS Mitral stenosis almost always includes a degree of insufficiency, it is not infrequently associated with aortic insufficiency also. The ma- jority of mitral stenoses are moderately developed or mild. With proper rest and cautious living and without added burden thrown upon the heart such cases live in comfort during many years, barring complications. Unfavorable Features.—Unfavorable features are increase of dilata- tion of the left ventricle, thrombosis and embolism, increasing arterial anemia, added pulmonary complications including cardiac asthma and dyspnea, edema, hydrothorax; albuminuria, added tricuspid insufficiency with decided hypotension and lowered pulse pressure and the engorge- ment of the abdominal viscera. Marked dropsy with mitral stenosis is due to the associated insuffi- ciency of the valve; with stenosis alone, it is not likely to be extensive. The pulse, with good compensation is small, regular, of good force and of nearly normal frequency. The pulse is easily obliterated by pressure, but under favorable conditions it is palpable between the beats. Blood pressure may not be changed. The greater difference is in the reduced pulse pressure because the arterial tree compensates in a large degree; the minimal pressure rises because of the vasoconstriction. The difference between systolic and diastolic pressure is not so marked as in well compensated mitral insufficiency. The process of cicatrization may continue in the muscle, change the chordae tendinae, “impairing at other places the functional activity of the heart muscle, and affecting the a.-v. bundle, depressing conductivity or producing nodal rhythm, thereby profoundly modifying the nature of the rhythm of the heart” (Mackenzie). With marked incompetence of the valve and stenosis, the character of the pulse is changed, it becomes rapid, small, partaking of the character of the “mitralized pulse.” Mitral stenosis which develops early in life is more serious than when developed in adult life, because of the tendency toward increase of ob- struction and the further fact, that the stenosed opening does not increase in size while the growth of the heart is progressive. Moon says that “such cases seldom reach the age of forty.” Broadbent gives the average age at death of these cases at thirty-three years for men, and thirty-seven years for women. Hirschfelder thirty-three and thirty-eight respectively. The significance of mitral stenosis in women is considered in con- nection with marriage and valvular disease. When the second sound is inaudible at the apex, there is great danger of decompensation, any added effort proves the presence of muscular insufficiency. The progressive character of the lesion in many cases accounts for the change of physical signs and other symptoms. ENDOCARDITIS 499 Fading or weakening of the presystolic murmur, with diminishing second pulmonary sound is evidence of failure of the right ventricle. The presystolic murmur is likely to disappear with the appearance of continuous irregularity of the heart and rapid pulse. Mitral stenosis associated with arteriosclerotic endocardial change offers a less favorable prognosis than do other forms of the disease. With the arteriosclerotic form of the disease, arhythmias are more fre- quent and often denote myocardial degeneration. Aortic Stenosis (obstruction).—Probably the majority of murmurs heard over the aortic valve are not due to true organic stenoses. Pure aortic obstruction is exceedingly grave. The murmurs are either func- tional (hemic), of arteriosclerotic or inflammatory origin. Eomberg analyzed 670 cases of valvular disease and found 17 un- complicated aortic stenoses—2.53 per cent. At Johns Hopkins Hospital aortic stenosis was found in 5 per cent of the valvular diseases. In practice it is found that most aortic stenoses after middle life are of arteriosclerotic origin, and that an aortic systolic murmur is often the first sign of the presence of the process; under such conditions there is increase of the second aortic sound with or without raised blood pressure. Hypertrophy of the left ventricle is a necessity to overcome the effects of aortic obstruction when it is decided. Marked dilatation is evidence of added insufficiency of the valve, a frequent combination; in these cases the pulse gives additional evidence for prognosis. The loud systolic murmur is often out of proportion to the amount of obstruction offered by the uneven or contracted cusps. Dilatation in varying degree is produced by aortic stenosis; hyper- trophy of the left ventricle is more dependable and lasting with aortic stenosis than with any other valvular lesion. Unfavorable Cases.—The unfavorable cases are those in which the obstruction is progressive, in which there may also be invasion of the coronary arteries and with final aortic insufficiency, dilatation, sec- ondary distant changes and arteriosclerotic changes in the kidney, with obstruction in the peripheral vessels. The terminal stage includes aortic insufficiency with myocardial degeneration and the usual picture of decompensation. The graphic study of the pulse offers valuable prognostic data. As a rule, in favorable cases the pulse is slow, regular, of good force, and the artery is easily palpable between beats. The pulse wave is small, is well sustained, its rise and fall are slow. The pulsus tardus is not unfavorable. The pulse tracing is more characteristic than with most other valvular lesions. Arhythmia shows itself in irregularity, in serious cases—the pulsus 500 DISEASES OF THE CIRCULATORY APPARATUS alternans and in occasional periods of extrasystoles, these depend upon the condition of the myocardium. True alternating pulse is always of serious significance. Blood pressure depends largely on the amount of sclerotic change in the peripheral vessels and in the aorta, as well as on the condition of the myocardium, the kidney vessels and many other factors. In the average case without serious complications the pressure is normal. Sudden death is less frequent than with aortic insufficiency; in most cases, long periods of symptoms of myocardial insufficiency precede death. This is not true of cases complicated with coronary disease and advanced myocardial weakness. Mitral stenosis is favorable to the development of pulmonary tuber- culosis. (See Tuberculosis.) Babcock found seven of his twenty cases of aortic stenosis with pulmonary tuberculosis. The prognosis of aortic stenosis will often be favorably influenced by the revelation of the Wassermann reaction of the blood and its prompt acceptance for therapeutic indications. Aortic Insufficiency.—Since the original classification of the disease by Corrigan, two forms of insufficiency have been considered: (a) The Functional Form, (b) The Organic Form. (a) Functional Form.—The functional form is due to the dilatation of the mouth of the aorta and is associated as a rule with aneurismal dilatations of the aorta or it is an accompaniment of pulmonary insuffi- ciency. It is exceedingly difficult to diagnosticate functional aortic insufficiency; I do not remember to have met with a case in which the diagnosis seemed to have been justified save as I found the aortic mouth wide open post mortem in connection with disease of the aorta. (b) Organic Form.—At this point we must once more impress upon the clinician the great value for prognosis of recognizing the character of the lesion, whether inflammatory (endocarditic) or arterial and degen- erative (arteriosclerotic). When rupture of the valves occurs from mechanical strain or trau- matism, it is associated with either ulcerative or sclerotic change, there- fore requires no separate consideration. This question has an important medicolegal hearing. I do not believe that rupture of the normal valve follows strain or accident. Experimentally it cannot be ruptured by the highest pressure to 'which it is ever subjected by man. The larger number of aortic insufficiencies are found in men, are of the arteriosclerotic form, are most frequent after middle life and depend upon the same factors for their production as general arteriofihrosis. A large number are of syphilitic origin; this is especially true of the many cases which have no history of acute endocarditis preceding and ENDOCAKDITIS 501 develop between the third and fourth decade of life. The positive Wasser- mann reaction proves the truth of these conclusions. The heart changes depend entirely upon the fact that the left ven- tricle is forced to supply the arterial tree with sufficient blood; this it can only do by compensating for the return of blood to its cavity during diastole through the insufficient valve which during systole was forced into the aorta. Naturally the amount of extra work thrown upon the left ventricle and the seriousness of the lesion depend upon the size of the leak, the length of time of the regurgitation, the pressure which must be overcome in .the arterial system (aorta particularly) and the extent of associated lesions in distant organs. Aortic insufficiency offers an unfavorable prognosis because the larger number of cases are advanced before treatment is instituted and being dependent upon arteriosclerosis are likely to be progressive. In the moderately advanced cases or where the processes are stationary patients may live during many years with compensation which makes light occupation possible and life comfortable. The endocarditic type offers a much better prognosis than does the arteriosclerotic. Arteriosclerotic insufficiency in young subjects with evidences of progression, uninfluenced by specific treatment advances rapidly to a fatal termination with a number of complications in distant organs. The Flint murmur, presystolic, heard over the mitral area accom- panies many cases of aortic insufficiency. Austin Flint first described this murmur and claimed that it was due to the functional narrowing of the orifice between the mitral cusps which was closed at the beginning of auricular systole. There has been much discussion and controversy over the true cause and significance of the Flint murmur. (Thayer, Guiteras, Gibson and others.) The consensus of opinion is in favor of Flint’s original contention, but for prognosis it must not be forgotten that true mitral stenosis may complicate the organic lesion. I have not found that the presence of the Flint murmur influenced the course of aortic insufficiency unfavorably. So long as the left ventricle is sufficiently compensated pulmonary stasis is prevented, but with its failure and its persistent dilatation, it develops and is not easily overcome. Blood pressure in the inflammatory form of aortic insufficiency is not so high as in the arteriosclerotic cases. A normal pulse rate with a nearly normal systolic and diastolic pressure is found only in cases with- out marked sclerosis and with very limited insufficiency. Fall of blood pressure is often unfavorable, whether produced by a weakened myocardium or by drugs. Hypertension and high pulse pressure are characteristic of aortic 502 DISEASES OF TIIE CIRCULATORY APPARATUS insufficiency and offer valuable data for prognosis as well as diagnosis. In no other cardiovascular disease is there such enormous difference in the maximum and minimum pressure. Once established, the general features of the Corrigan or trip-hammer pulse persist until changed by myocardial fatigue. The wave is large, the upstroke sudden, the pulse is collapsed during diastole. The sphygmographic tracing may be safely relied upon for it is characteristic and promptly shows the break when it occurs, which is due to extreme dilatation and myocardial revolt. In favorable cases the pulse rate is slow and regular. With a rapid pulse, ventricular extrasystoles, evidence of dilatation and myocardial weakness, and the bigeminal and irregular pulse the outlook is serious. The laboring heart, thickened and visible throbbing arteries are evi- dences which must be studied with the associated features for the correct interpretation of their prognostic significance, also the capillary pulse. The snappy second sound is found in cases in which the peripheral resistance demands the “slamming of the door” as Lauder Brunton has so forcibly expressed the phenomenon. Suddenly arising mitral insufficiency (muscular relative insuffi- ciency) is due to extreme dilatation of the left ventricle and is un- favorable. The association of coronary disease with aortic insufficiency offers only the most dismal forecast and yet life may be prolonged by rational living in many of these cases. (See Angina Pectoris.) It is in these cases that family history is of great prognostic value. The recurring strain to which the arteries are subjected by the enor- mous hypertrophy of the left ventricle in many cases is a factor in pro- ducing or increasing arteriosclerotic change. The influence of arteriosclerotic changes in the brain, kidney, and within the splanchnic area is paramount. (See Cerebral Apoplexy, Arteriosclerotic Nephritis and Arteriosclerosis.) Sudden death is more frequent with aortic insufficiency than with any other valvular lesion, (See same chapter, General Considerations.) Subjective symptoms which are unfavorable include faintness, pre- cordial pains, dyspnea, somnolence and mental torpor. In the prognosis of aortic insufficiency no single symptom can serve to give a reliable forecast. The multitude of lesions which may be pro- duced by the sclerosis, of which the valvular defect is only a part, takes the clinician into an enormous field. In the final analysis there are naturally many factors to be considered, but the paramount issue must always include the accommodation of the ventricle to withstand the strain by sufficient dilatation and hypertrophy, i. e., to hold compensation. “The field of cardiac response is the only true and safe guide” (Mac- kenzie). ENDOCARDITIS 503 Tricuspid Insufficiency.—Lesions of the tricuspid valve are rare. In the preceding pages we have considered the association of tricuspid in- sufficiency with other heart and lung lesions. It is not likely to exist independently. It is frequently present as an expression of muscular and relative insufficiency, and with diseases of the lung or the left heart, it is always a serious complication. The recognition of insufficiency is made possible by the accompany- ing venous pulse and pulsating liver. True tricuspid insufficiency leads to death. We have no exception to report. Colbeck says “the precise estimate of the leakage is of less importance than the determination of the exact causes which have led to the occurrence of the lesion.” The chief points to be considered are: 1. “The degree of enlargement of the right ventricle and auricle. 2. “The presence or absence of venous pulsation in the neck. 3. “The presence or absence of pulsation of the liver and the degree of enlargement of the organ. 4. “The degree of arterial anemia.” Tricuspid Stenosis.—Tricuspid stenosis is not found without insuffi- ciency, compensation is out of the question (Romberg). Sphygmographic tracings may lead to the suspicion of the existence of the lesion. Congenital defects are sometimes associated with fetal endocarditis causing tricuspid stenosis. (See Congenital Defects of the Heart.) The acquired form is more frequent in women than in men and is secondary to mitral stenosis. The two lesions are almost always asso- ciated, and both are more common in women. The rise in pressure in the right ventricle following mitral stenosis “causes strain and irrita- tion,” and invites tricuspid change. The right side of the heart is more frequently the seat of valvular murmurs with the malignant than with the usual forms of endocarditis. The blood stream through the tricuspid orifice is obstructed and in- creased, demand is made on the right auricle, hypertrophy results with more or less dilatation. The amount of dilatation also depends on the associated insufficiency of the valve. Unfavorable conditions with all tricuspid disease are congestion of the portal and general venous system. The amount of hypertrophy and dilatation of the right ventricle depends largely on the degree of mitral stenosis, as does the pulmonary engorgement also. Defects of the Pulmonary Valve.—Most murmurs heard in the pul- monary area are of functional hemic origin, they are systolic and, con- sidered alone, are of but little significance. Cardiorespiratory murmurs and mitral murmurs are often heard in the pulmonary area. Stenosis is usually of congenital origin and predisposes to tubercu- DISEASES OF THE CIRCULATORY APPARATUS 504 losis. For a full consideration of its prognosis see Congenital Stenosis of the Pulmonary Valve. Pulmonary Insufficiency.—Pulmonary insufficiency is rarely acquired, it may occasionally be of syphilitic origin. It occurs with kyphosis, mitral stenosis and narrowing of the pulmonary artery or its branches, when it is a relative insufficiency. Aneurism of the aorta may also be associated with relative pulmonary insufficiency (Romberg). Barie reports 58 cases and claims that it may be an acquired lesion most frequent between the ages of eighteen and thirty-four. The right ventricle enlarges, there is great venous congestion, jugular and hepatic pulsation, cyanosis and clubbed fingers. The prognosis is only favorable so long as the right ventricle proves sufficient. The regurgitation is probably slight if the murmur does not efface the second sound. The complete effacement of the second sound is evidence of serious insufficiency of the valve. 3. Arteriosclerotic and Syphilitic Endocarditis The influence of the degenerative types of valvular disease depending on arteriosclerosis and syphilis is fully considered in this chapter and in connection with the study of cardiovascular syphilis and need not he repeated. The progressive and unfavorable cases of valvular disease are those of the degenerative or arteriosclerotic type, particularly between the twentieth and fiftieth year. In older individuals the process is better borne and may remain stationary during many years. The beginner may be led by the presence of a systolic aortic murmur with moderate arteriosclerosis to offer a grave prognosis, this is not justi- fied in the average case which remains under reasonable control. The blood pressure study of these cases gives valuable information in connection with a thorough appreciation of the coronary circulation and the kidney function. In the degenerative types of disease particularly, the frequent Ront- gen examination and the use of graphic methods are a necessity for the valuable information which they add. 4. Combined Valvular Lesions From the foregoing consideration of the acute and chronic cardiop- athies it is clearly evident that combined lesions are more frequent than are the single defects. We have seen mitral and aortic lesions together with full compensar tion during many years and death resulting from intercurrent disease. The mitral lesions combined, as has been shown, may also continue ENDOCARDITIS 505 without causing serious inconvenience in many cases; there are always the dangers of decompensation to which we have repeatedly alluded. There are combinations of lesions which act favorably; thus aortic stenosis may reduce the amount of regurgitation in aortic insufficiency, and the same occasionally happens when stenosis and insufficiency are combined at the mitral opening. The prognosis of the lesions included in the combination can only be given after the consideration of the facts men- tioned in connection with the individual valvular defects. Romberg’s statistics show mitral insufficiency and mitral stenosis combined in 19.7 per cent alone, and in 7.97 per cent with valvular lesions. Aortic and mitral insufficiencies were combined in 12.69 per cent. In 4.93 per cent aortic and mitral insufficiencies with mitral stenosis were combined. The gravest combination is aortic insufficiency and stenosis 5.2 per cent. In 4.05 per cent there were besides aortic insufficiency and stenosis other valvular lesions. Tricuspid and mitral lesions were combined in 1.97 per cent of Romberg’s cases. References Amsler. Korresp. Schweizer Aerzte, 1912. Aschoff & Taivara. Tawara, Herzschwache. Jena, 1906. Babcock.

Functional Disorders of the Heart In most cases the functional disorders of the heart are not diseases \per se, hut include the symptoms which are produced hy the derangement of the nervous or muscular mechanism of the heart, or both; associated with true organic lesions. There are exceptions to this definition but as Colbeck has truly said, after committing himself to practically the same definition, “In other words, ‘functional disorders’ of the heart form part of many different groups of symptoms, which severally constitute ‘a dis- ease’ properly so called. A clear grasp of this conception will go far to dissipate much of the difficulty and confusion that has grown up around the subject of functional affections of the heart.” Functional affections of the heart which include among their leading symptoms, palpitation, arrhythmia pain and a train of neurasthenic symp- toms, may arise from changes in many organs. We find functional dis- turbances with all cardiovascular diseases, affections of the nerves and ganglia of the heart, the pericardium, the myocardium, the aorta and FUNCTIONAL DISORDERS OF THE HEART 507 coronaries, with arteriosclerosis and with vasomotor disturbances which influence arterial pressure. Diseases of the nervous system are often associated with functional disturbances of the heart. Neurasthenia and hysteria are prominent among these. Grave organic diseases of the brain and cord—tabes dorsalis, menin- gitis, brain tumor, apoplexy, epilepsy, injury to the brain, lesions of the medulla, mania, manic depressive states and general progressive paral- ysis, all, at some time during their progress develop characteristic evi- dences of functional derangement of the heart. The thyroid heart (hyperthyroidea) is separately considered. (Dis- eases of the Ductless Glands.) The influence of the diseases of the lung, tuberculosis particularly, is paramount in causing disturbed heart function and is separately con- sidered. (Tuberculosis.) The large number of neurasthenics with derangements of the gastro- intestinal tract adds an enormous material in which nervous manifesta- tions are in the foreground. These cases include neuropathies ivith ptoses (Glenard’s Disease) who are rarely without phobias of some hind, due to deranged function of the heart of reflex character. The influence of constitutional diseases including all forms of anemia, gout, diabetes, so-called rheumatism, the leukemias, the acute and chronic infections, each is a factor in producing perverted heart function. In considering myocardial disease and hypertrophy we mentioned the influence of masturbation, ovarian and uterine disease. Toxic states, including uremia, acidosis, the excessive use of alcohol, tea, coffee, tobacco, each modifies the action of the heart. The effect of lead and other drugs including digitalis, strophanthus, aconite, bella- donna, the bromids, and iodids, is largely influenced by existing resistance and idiosyncrasy when used in small doses, when in larger dosage, the physiologic effect on the separate functions of the heart are promptly manifested. We consider among the functional derangements: 1. Palpitation. 2. (a) Paroxysmal Tachycardia and (b) Simple Tachycardia. 3. Bradycardia. 4. Arhythmia. 5. The Neurasthenic State. 1. Palpitation The sensation which is distinctly perceptible to the individual, caused by the undue frequency of the regular or irregular heart, is known as palpitation. It is probably the most frequent of all sensations referred 508 DISEASES OF THE CIRCULATORY APPARATUS to the heart, causes in the overwrought and neurasthenic or nervous patient the fear of death and in the majority of cases is not associated with organic disease of the heart. Palpitation in most cases is due to influences which act through the nervous system and is caused by hurry, worry, excitement, fatigue and kindred factors which are evanescent in their effect. The subjects whose hearts are promptly ungeared belong to the neurasthenic class—true neuropaths. Palpitation may he an expression of a weak heart muscle, when, as a rule, there are extrasystoles. Hirschfelder has demonstrated that palpi- tation may persist “without any motor disturbance in the heart’s action and without any change in the reflex response of the heart to various stimuli.” The majority of palpitations are without serious significance and exist without organic disease of the heart. In the majority of cases in which the symptom is not of organic origin it either disappears suddenly to return when depressing or toxic factors are added, or it yields after a painstaking investigation of the patient’s history leads to the relief of its cause. In all cases which remain unexplained by physical examination the possibility of tea, coffee, tobacco, alcohol, coal tar preparations, thyroid extract and other drugs as the possible exciting cause should be considered. Distant and unexpected lesions are often recognized as provocative of palpitation, their relief is followed hy the disappearance of the rapid hearty The disagreeable and depressing mental pang which neurotics suffer with palpitation makes them wrretched during the continuance of the symptom. The palpitations due to the infections, usually during the period of convalescence (pneumonia and diphtheria particularly), offer a good prognosis with rest and reassurance. Palpitation with menstrual anomalies at the menopause, puberty and during menstruation may appear serious at times, but always yield when without organic fundament. There are some women, men occasionally, who from the slightest imaginable cause between the fifteenth and about the thirty-fifth year of life promptly “blush and palpitate,” in whom the attacks are evanescent, exceedingly annoying, hut without effect on their general condition. 2. (a) Paroxysmal Tachycardia For over half a century paroxysmal tachycardia has been recognized by the profession as a symptom complex without a clear conception of its nature or the method of its production. In all cases the striking features are those which were included in Bouveret’s article and the works of A. Hotfman. FUNCTIONAL DISORDERS OF THE HEART 509 Clinical experiences prove that in most cases the tachycardia begins without warning and ends with equal suddenness. Hoffman’s tracings show the characteristic change of the heart rate within a single cycle. The heart rate during the 'paroxysm is either double, treble, or quadruple that of the patient’s heart rate just before the attack commenced. These characteristics differentiate paroxysmal and simple tachycardia or exces- sive palpitation. For our purposes of prognosis the differential diagnosis of the vari- eties of tachycardia is important. My experience with paroxysmal tachycardia does not agree with those who claim that it is as frequent in men as in women. I have rarely found paroxysmal tachycardia in men without positive evidences of hyperthyroidea, this is not true of women who have presented the uncom- plicated idiopathic variety of the disease, which justified the diagnosis of paroxysmal tachycardia. The author does not consider those of auricular fibrillation with mitral stenosis (not infrequent) as essential tachycardia. With serious attacks, pulmonary congestion may become alarming, the pressure in the pulmonary circuit is then high, while the systolic blood pressure and pulse pressure is usually low. The alarming symp- toms include the enormous tachycardia, pulmonary stasis, cerebral anemia, low blood pressure and pulse pressure, occasionally dyspnea and albuminuria. There are cases in which no remedy influences the paroxysm which yields without known cause and often leaves the patient without marked weakness. In occasional cases sudden acute dilatation causes death after the tachycardia ceases. A case which we watched over twenty years, with attacks recurring at intervals of from three or four months to as many years, recovered from a slight attack, seemed uninfluenced; the following day while shopping she fell forward on the counter and immediately expired. This is not a frequent occurrence. The fluoroscope has demonstrated to the satisfaction of those who have had opportunity to examine the heart during the attack, that the heart is not dilated but is decreased in size and that in severe cases it dilates toivard the end of the paroxysm. The embryonic sounds (originally so characterized by Hothnagel) are heard during the attack. In the more severe cases the liver remains permanently enlarged. The duration of paroxysmal tachycardia is variable. I have had two cases under observation (both women) during the past twenty years. Occasionally the seizures cease after a few years of recurrence. The only death in our series is above mentioned after insufficient rest follow- ing an apparently insignificant paroxysm. 510 DISEASES OF THE CIRCULATORY APPARATUS Osier reports a case of H. C. Wood in a physician “who in his eighty- seventh year had had attacks at intervals from his thirty-seventh year.” In this case “the taking of ice-water or strong coffee would arrest the attacks.” When the attacks cease all patients promptly recognize the “Hop” for which they have learned to wait. 2. (b) Simple Tachycardia An abnormally rapid heart in which the individual is as a rule uncon- scious of the heat, which is without the features of paroxysmal tachy- cardia, may be considered simple tachycardia. In many cases tachycardia is physiological, as during pregnancy, during lactation; there are per- fectly normal hearts which continue abnormally rapid throughout life without causing inconvenience. The abnormally rapid hearts and their baneful influence on prognosis of the acute infections are considered with the separate diseases. In all acute infections prolonged tachycardia is evidence of serious cardiac toxemia. It must be accented that tachycardia during the incipient stage of most acute infections is evidence of virulent infection and vasomotor paralysis. Tachycardia with cerebral lesions is evidence of a lesion of the pneumogastric nerve, which is due to an anatomical lesion of the nerve or to pressure which after a period of irritation led to paralysis. Causes.—Thrombosis and embolism, brain tumor, bulbar paralysis, myasthenia gravis, Landry’s paralysis, acute myelitis, acute poliencepha- litis, lateral sclerosis (amyotrophic), disseminated sclerosis and hemor- rhage of the fourth ventricle are mentioned by von ISTeusser among the causes of simple tachycardia. Charcot and Oppenheim also mention the crises of tabes and syringomyelia with bulbar manifestations. There is no disease of the- brain or cerebral injury (fracture in- cluded), which may not cause tachycardia. In all cases tachycardia influences prognosis unfavorably but the prognosis depends entirely on the nature and extent of its cause. Irritable hearts and delirious hearts (Delirium Cordis) are asso- ciated with enormous rapidity of action, usually there is some precordial pain, the subjects are nervous individuals, easily ungeared. J. M. Da Costa reported the cases of 200 soldiers with fever and overstrain in 17 per cent, diarrhea with mild typhoid fever in 30.5 per cent; hard field service; excessive marching 38.5 per cent; doubtful causes in 18 per cent; in which there were irritable hearts. Many cases of irritable hearts are associated with myocardial degen- eration and demand a guarded prognosis. In some cases the irritable heart is found in young recruits unaccustomed to “the strain, mental FUNCTIONAL DISORDERS OF THE HEART 511 excitement and insufficient training.” Hypertrophy is occasionally followed by dilatation in grave cases. 3. Bradycardia An abnormally slow heart is synonymous with bradycardia. True bradycardia includes only those cases in which all of the heart chambers beat equally slow. The other forms of bradycardia according to Mackenzie are “false”—they are due (a) to a missed beat, in which the ventricle contracts, but the pulse wave because of the feeble contrac- tion fails to reach the wrist, (&) “certain cases of nodal rhythm where the auricle has ceased to beat, or does so synchronously with the ven- tricle,” and (c) “where the stimulus is blocked between auricle and ventricle so that the auricle beats at its normal rhythm and the ventricle does not respond to the auricular systole, but pursues an independent and slow rhythm” (heart block). Bradycardia is not necessarily pathologic. There are individuals who always have a slow pulse and are never influenced unfavorably thereby. During labor, the pulse may be normally slow. The leading causes of bradycardia summarized by von Neusser are: Toxic substances: Tobacco—Nicotine Lead Physostigmin—Muscarin Potash salts—Picric Acid. Autotoxic substances: Ptomain poisoning Bile Urea Acetone—Acetic Acid. Convalescence from Acute Infectious Diseases—Rheumatism and Pneumonia particularly. StoTces-Adams Disease. Coronary and Myocardial Disease. Diseases of the brain: Gummatat Tuberculous and other tumors Lesions of the medulla oblongata Hyperemia of the vagus center Meningitis Concussion of the brain Cerebral apoplexy Thrombosis and Embolism Acute hydrocephalus 512 DISEASES OF THE CIRCULATORY APPARATUS Hemorrhage of the fourth ventricle Facial Paralysis Cysticerci of the fourth ventricle. Hysteria. Melancholia. Basedow’s Disease (during transition from Basedow to myxedema). Pressure on the vagus: Carcinomatous glands and tuberculous growth of the neck. Cancer of the Stomach, gastric ulcer and gall-stone colic. Injuries to the spinal cord. Diseases of the Ear: Foreign bodies in the external ear; reflex irritation from the auricular branch of the vagus. Each of these many possible causes of bradycardia suggests its own prognosis. When bradycardia arises suddenly during the active period of pneu- monia or any grave infection, it usually indicates incipient meningeal invasion. During the period of convalescence it is not usually of signifi- cance with proper care and is not infrequent. With cerebral hemorrhage moderate bradycardia is more favorable than tachycardia, which with high temperature is almost always fatal. With cancer of the stomach bradycardia during the early stage may assist in diagnosis, for it is not infrequent and may, by leading to prompt recognition influence prognosis favorably. Bradycardia due to syphilitic lesions offers a favorable prognosis— when attacked early and vigorously. Heart block has been separately considered. The influence of digi- talis and kindred remedies in slowing the heart must be considered in connection with the study of individual cases. 4. Arhythmia The Arhythmias have been considered in connection with the dis- eases of the myocardium. S. The Neurasthenic State There are but few neurasthenics without complaints referable to the heart. These complaints are numerous, vary from day to day and are always interpreted as serious by the patient who soon becomes self- centered with the heart symptoms in the ascendency. There are often acute exacerbations of symptoms resembling organic FUNCTIONAL DISORDERS OF THE HEART 513 crises which are aggravated hy the autosuggestion and associated fear of the patient. In some cases symptoms continue during long periods; in other cases nocturnal attacks and periodicity are characteristic. Anginoid attacks with marked development of an emotional element accent the fears of the neurasthenic. Some patients are fairly well between the acute attacks hut live in fear of this recurrence. The mental pang suffered hy the cardiac neurasthenic is often pitiful. The pulse shows great variations in frequency and in character at different times, and under varying conditions. It may be surprisingly slow at one time, exceedingly rapid at another. Intermission and ar- hythmia with marked excitement and great fear of impending danger and associated hysteria are noted in some cases. Sensory symptoms referable to the extremities, with hyperesthetic areas, at times to the precordium are frequent, and add to the discom- forts and fears. The prognosis of the neurasthenic state is favorable. The most potent factor in its prognosis is the personal equation of the attendant whose tact and resources will often be taxed during long periods, but by so regulating the lives of these individuals as to remove them from them- selves and substituting a healthy suggestion for the ever recurring and depressing autosuggestion and other appropriate mental pabulum, these patients make satisfactory recoveries. Relapse is frequent when depressing factors are usually responsible. References Bouveret. De la tachycardie paroxstique essentielle. Rev. de Med., Paris, 1889, ix, 753-836.' Charcot & Oppenheim.

Symptomatic Secondary Anemia Formerly the term “Anemia” included only a reduction in the num- ber of red blood corpuscles. Anemia is now defined as a condition in which the blood as a whole, the red blood corpuscles or the hemoglobin, or both, are diminished. Oligemia includes a condition of the blood in which all of its con- stituents are diminished. Oligocythemia is a condition in which the red blood corpuscles are reduced. Chlorosis or oligochromemia denotes a marked reduction in the amount of hemoglobin in the individual cell. Local anemia or ischemia is usually either transitory or permanent. I consider both these conditions in connection with vascular spasm and arterial changes, such as endarteritis, which may choke the parts beyond the point of obliteration and lead to deep tissue changes—gangrene, necrobiosis and cyanosis (See separate diseases). General Anemia The larger number of aneviias are of secondary origin and symp- tomatic. Anemia due to loss of blood may be (a) acute or (b) chronic. (a) Acute Anemia (Hemorrhagic).—Hemorrhage may cause sudden acute anemia reducing at once every element which normally floats through the vessels and naturally the amount of blood. 514 ANEMIA 515 Suddenly arising pallor, anemia, should always lead to the suspicion of hemorrhage. When external, the recognition of the cause is easy; when hemorrhage is internal, it is more difficult. With typhoid fever, sudden pallor and collapse without symptoms of peritonitis or intestinal perforation should always lead to the suspicion of intestinal hemorrhage, the blood may be held in the intestine for several hours before it appears in the stool. (See Typhoid Fever.) Sudden anemia in women whose menstrual flow has been irregular or absent, should always lead to the strong suspicion of ectopic pregnancy with tubal rupture. The prog- nosis of this condition is brilliant in cases recognized early and promptly treated radically. The clinician wall make no more satisfactory con- quests in the practice of his profession than in the prompt diagnosis of ruptured tubal pregnancy. These patients may be thoroughly exsan- guinated and still recover. Accidents during delivery, placenta previa, uterine inertia, and laceration may cause serious and threatening- depletion. Malignant growths ulcerating or rupturing, may cause sudden and fatal anemia. One of our cases died suddenly from internal hemorrhage due to the rupture of a rapidly growing encephaloid cancer of the liver. The ability of the individual to immediately furnish much of the water content of the separate organs to the blood vessels as these are depleted by sudden hemorrhage, is one of the important factors in saving life in acute anemia resulting from hemorrhage, by tiding him over the critical period. Patients who are depleted or below par, do not bear sudden loss of blood well, for the response to the added demand on the bone marrow is slow and unsatisfactory. The young and healthy bear the loss of blood better and react quicker than do older subjects. It has been found experi- mentally, that with the loss of from £ to of the total blood volume (1/13 of the body weight) regeneration usually follows in from 2 to 6 weeks (Turk). Bierfreund found that with the loss of 25 per cent of the entire blood in children, complete regeneration followed in 22| days, in healthy adults in 17-| days, and in the aged in 28 days. It may be assumed that oligocythemia and oligochromemia are con- ditions which, with the reduction of the blood plasma are promptly com- pensated by nature’s processes. The danger point in all acute hemor- rhage is reached if one-half or more of the entire volume of blood is lost. Morawitz says that “the loss of more than two liters must be viewed writh great concern and offers an unfavorable prognosis.” A low blood count and cellular changes which show lack of regenerative power and marked enfeeblement is an unfavorable combination. If the underlying factor is removable, even under these threatening conditions, recovery often follows. Tiirk makes the unqualified statement that the exhaus- tion of the patient offers the indications for the immediate attempt to 516 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS overcome the prime factor because extreme conditions may ultimately yield to radical treatment. The plasma of the blood increases first after depleting hemorrhage, the regeneration of the red blood corpuscles is slower, while the hemo- globin is last to return to the normal level. Sudden hemorrhage stimu- lates both the erythroblastic and myelogenic tissues to activity, which accounts for the prompt leukocytosis (posthemorrhagic leukocytosis) which follows the loss of blood. The return of normoblasts and young red cells in abnormally large numbers is always favorable. The leuko- cytosis and excess of normoblasts, if present, are promptly changed to approximately average conditions. The pulse may be small and rapid, the heart sounds distant and feeble, the associated symptoms extreme; all these conditions usually yield with the control of the hemorrhage. The prognosis must depend finally upon the cause of the hemorrhage, the extent of damage done to the tissues, the resistance of the patient and a variety of other conditions which present in the individual case. (b) Chronic Anemia (Hemorrhagic).—The anemia which is chronic and associated with hookworm disease, has been separately considered (See Ankylostomiasis). Long continued drain leads to chronic blood changes. The gravity of the anemia depends upon the amount and dura- tion of the hemorrhages, its localization and the cause. The leading causes of chronic hemorrhagic anemia are excessive menorrhagia, metror- rhagia, bleeding piles, intestinal and gastric hemorrhage due to ulcers of the duodenum, intestine or neoplasms (cancer), varices, epistaxis, pur- pura, hemophilia, hematuria due to organic disease or parasites. The grave anemia of bothriocephalus latus is separately considered (See Pernicious Anemia and Bothriocephalus Anemia). The blood changes of chronic (hemorrhagic) anemia include a char- acteristic picture. In extreme cases hemoglobin may sink below 20 per cent, and if the cause can be overcome, complete return to health usually follows. In the grave types normoblasts, polychromatic erythrocytes, megaloblasts and megalocytes are found. In the more favorable cases normoblasts, polychromatic erythrocytes, poikilocytes and microcytes are present. The red count falling below 1,000,000 in the acute and chronic cases is always ominous with the correspondingly low color index. Turk says 20 per cent of such cases offer a doubtful prognosis. The secondary chronic anemias due to malignancy, cachexia and infection influence the forecast of these conditions. Tuberculosis, cancer, sarcoma, nephritis, typhoid fever, malaria, the intoxicants, including lead, mercury, arsenic, antimony and other poisons are all associated with more or less anemia as these diseases advance. There is slow “latent bleeding” due to malignant growths of the intestine which during long periods offers no subjective or objective symptoms ANEMIA 517 save gradually increasing anemia, the cause of which may be detected by the presence of occult blood in the stools. The prognosis of all depends upon the ability to remove the cause. The slow bleeding of cancer (gas- tric and intestinal) is likely to show greater cachexia than anemia and this is of value in differentiating pernicious anemia, in which the anemia is out of proportion to the cachexia. Faulty living, ventilation, diet and social conditions influence the blood state besides leading to primary conditions upon which anemia is usually dependent. With chronic bleeding and associated anemia or any form of secondary chronic anemia the unfavorable features include besides heart weakness and the unfa- vorable blood picture, edema, vertigo, tinnitus aurium, headache and dyspnea. In cases which are operable the prognosis is best in which the hemo- globin per cent does not fall below 40. Von Voorden believes that any form of anemia may ultimately lead to complete exhaustion of the bone marrow which may present the clinical features and the blood picture of pernicious anemia. If this is true the occurrence is exceedingly rare. The author has never in practice seen a case of secondary anemia develop the pernicious or essential disease. Bierfreund. Arch. f. klin.

Primary or Essential Anemia (a) Chlorosis (Green sickness, Oligochromemia) Chlorosis is a condition of the blood in which there is a decided lowering of blood coloring matter—hemoglobin—which is limited to the female, is likely to develop during the period of sexual development, is relieved by iron, is never per se a serious disease, though it recurs easily, is materially and promptly influenced by the general condition of the patient. The blood picture of chlorosis is characteristic. Chlorosis may be diagnosticated in the absence of the picture of true anemia when there is a decided reduction in the percentage of hemoglobin. Most chlorotics 518 DISEASES OF BLOOD AND HEMOPOIETIC OKGANS are also oligocythemic (red corpuscles reduced). In the severe cases the red corpuscles number from 2,5u0,000 to 3,500,000 per c. mm. Hayem reports extreme counts as low as 1,300,000 per c. mm. Cabot averaged 77 cases at 4,050,000 per c. mm. Bramwell averaged 80 cases at 3,437,000 per c. mm. Mild cases show but slight reduction in the red count. Besides the reduced hemoglobin, there is an excess of blood serum (polyplasma), the regenerative power of the blood is reduced, the leukocytic count is not materially disturbed, the blood platelets are in- creased. The pathologic, cause of chlorosis is unknown. Virchow be- lieved that there was, in most cases, a congenital narrowing of the larger blood vessels (aorta). Extreme chlorosis is associated with marked subjective symptoms; prominent among these are dyspnea, palpitation, exhaustion, menstrual anomalies, gastro-intestinal disturbance, obstipation and excessively devel- oped emotional element, perverted appetite, vertigo, tinnitus aurium and the characteristic pallor of the mucous membranes and green colored skin. The extremities are cold much of the time. Chlorotics lack normal resistance. In these cases hemic murmurs (systolic) are usually present. The foregoing features are present and persist until relieved by some form of treatment. The majority of chlorotic girls yield to proper diet, ventilation and prolonged rest. Uncomplicated chlorosis always yields to iron and other rational treatment. ISTo patient dies of chlorosis unless there has been some complication. Pulmonary embolism and thrombosis are rare but fatal complications; many men of large experience have never met such cases. The tibial or femoral vessels are occasionally the seat of thrombosis. With improvement of the general condition the color index is raised, the blood picture changes and all attending symptoms gradually yield. The return to a normal condition is often exceedingly slow and an irritable heart may persist during varying periods. The perverted appetite is also a source of annoyance in some cases during long periods. Chlorotics are liable to relapse on slight, sometimes with- out hnown cause; seasonal and climatic influences are powerful. Change of scene with rest often effects lasting cure. Progressive loss of weight with chlorosis or any form of anemia argues against uncomplicated blood changes and demands search for the underly- ing cause before a forecast is justified. The influence of intestinal toxemia in continuing or causing chlorosis should be considered in the individual case. Sir Andrew Clark strongly advocated the intestinal origin of chlorosis and believed that constipation was the leading factor. In America, foreign girls between the ages of 12 and 16, shortly after their arrival, often become chlorotic and amenorrheic. This condition usually yields after a few months of treatment. Girls coming to cities from the country also develop chlorosis very frequently and menstrual ANEMIA 519 anomalies. It has been noted that recurrence is finally prevented by pregnancy. Occasional cases remain but slightly changed during long periods; they are veritable chronic chlorotics without many annoying symptoms, but the blood picture does not return to normal. Some of these continue chloranemic throughout their lives. Among the frequent complications of chlorosis is gastric ulcer. The prognosis of this condi- tion is separately considered. (See Gastric Ulcer.) Chlorosis with exophthalmic goiter is repeatedly met in practice and usually yields with the other symptoms of hyperthyroidea. Acute nephritis and endocarditis mentioned by Bramwell as sequelae of chlorosis we have never experi- enced. There is a strong tendency to self cure after the twenty-fifth or thirtieth year.

References (6) Pernicious Anemia (Addisons Anemia (1855), Progressive Pernicious Anemia, Malignant Anemia, Infectious Anemia, Biermers Essential Anemia, Megalo- blastic Anemia) Pernicious anemia is a chronic progessive, possibily infectious disease characterized by (hemolysis) destruction of large numbers of red blood corpuscles in which the remnant of corpuscles contains a high hemoglobin per cent; the disease presents a blood picture which is classic, though not absolutely pathognomonic; it often shows long periods of latency, has periods of exacerbation which are followed by remission in some cases, may either early or late present striking features showing involvement of the nervous system and in almost all cases leads to death with symptoms of toxemia. In rare cases the course is acute. There are besides the destruction of the blood elements, marked changes in the bone marrow, surprising retention of the body fat in spite of advancing disease, hemor- rhages into the skin and serous cavities, dilatation of the heart, also myocardial degeneration, usually atrophy of the gastric and intestinal fol- licles; in the terminal stages, enlargement and fatty degeneration of the liver, which organ contains an excess of iron, with or without slight en- largement of the spleen. As a rule, the spleen remains negative so far as its size and contour are concerned. The changes in the bone marrow 520 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS are easily recognized. The color is abnormally red, lymphoid cells and a large number of normoblasts (Ehrlich’s gigantoblasts) are seen. Licht- heim first called attention to the symptoms and changes in the nervous system. These are important in the diagnosis and prognosis of individual cases and include sclerosis of the cord in patches, mainly affecting the posterior columns and the ganglionic cells of the sympathetic. I char- acterize the nervous symptoms as “ Lichtheim symptoms” and will again refer to the complex. There is no treatise which details the clinical his- tory of the disease more accurately than that given by Addison in 1855 under the caption of idiopathic anemia. History.—Grawitz in considering the history of pernicious anemia mentions Combe as having reported a case in 1822, another by Marshall Hall in 1843 and Lebert in 1853 and 1868 call attention to parallel cases developed during pregnancy. Cazenave, in 1860 with Lebert, called at- tention to essential anemia without pregnancy. Combe in reporting the original case wrote “A marked instance of a very peculiar disease—If any train of symptoms may be allowed to constitute anemia a generic disease, the following may be considered a sample of it. in its most idiopathic form.” The disease is known on the continent of Europe as Btermer’s Pro- gressive Anemia or Essential Anemia; the original classic description of the disease by Addison which antedated Biermer’s redescription by at least 17 years had been practically ignored even in England; in spite of the fact that the colleagues of Addison at Guy’s Hospital were acquainted with his description but little attention was given to its diagnosis until their minds were refreshed by Biermer’s treatise. The failure to recog- nize this form of anemia during those days is accented by the fact that Pye Smith in 1882 presented a complete bibliography and was unable to gather more than 102 cases from various sources. Heredity.—Any grave anemia, pernicious particularly, in which there is a strong hereditary element is likely to be rapidly progressive and long periods of latency are not frequent. We have in our cases noted the fre- quency with which several members of the same family are afflicted. It is not unusual to find one or more brothers and sisters, or one parent and one or several children with essential anemia; all running the typical course to death. We have never met a case of pernicious anemia in a child below the age of 15 years. Osier reports one case in a boy ten years of age. The large majority of our cases were between 33 and 40 years of age. We do not include a single case in our old or new series in which pregnancy or prolonged lactation caused the disease. Pepper, Channing and Gusserow called attention to the influence of pregnancy on the pro- duction of essential anemia. Probably with modern hematologic methods of differentiation most of these cases would now prove to be secondary and dependent upon long continued drain. ANEMIA 521 Blood Picture.—The blood picture of pernicious anemia is sufficiently characteristic to lead to its diagnosis in the majority of cases. There are occasional exceptions for thorough hematologists have been forced to concede that rare grave anemias, non-pernicious, do present pictures which so closely resemble the pernicious type that error is possible. Ehrlich contends that the blood picture alone is so characteristic as to make diagnosis possible. The dictum to which the Ehrlich school adheres is that “Megaloblasts and Megalocytes show megaloblastic degeneration and this is the main cause of pernicious anemia.” Bothriocephalus anemia which in cases not too far advanced offers a fair prognosis, presents blood features which are so closely allied to the essential pernicious type of the disease as to make differentiation impos- sible and most authorities agree that the blood pictures are parallel (See Bothriocephalus Latus). Unquestionably advanced bothriocephalus latus anemia cannot from the blood picture be differentiated from true perni- cious anemia and such patients die with all of the clinical manifestations of essential anemia. I have seen recovery from grave bothriocephalus anemia follow the expulsion of the worm which is usually dead or sick and by its presence caused toxemia. The erythrocyte count is lowered in the advanced or most serious cases to 1,000,000 per c. mm. or below. The average in our cases early has been between 2,500,000 and 3,500,000. The blood is pale yellow, abnor- mally fluid, and clotting is slow and unsatisfactory. In some cases the prick is followed by oozing and the surrounding skin becomes ecchymotic (spurious hemophilia). Blood counts in which the erythrocytes fall below 1,000,000 are rapidly fatal. Prognosticating from the blood picture we quote Cabot: “1. Severe (rapidly fatal) (a) Extreme progressive anemia. (b) High color index. (c) Increase in size of red cells. (d) Denegerative changes. (e) Numerous megaloblasts. (f) Few or no normoblasts. (g) Lymphocytosis.” “2. Less severe (slower course) (a) Remissions. (b) Normal or low color index. (c) Normal sized cells. (d) No degenerative changes. (e) Few megaloblasts. (f) Numerous normoblasts. (g) Normal percentage of adult cells.” The size of the red cells is increased—megaloblasts and megalocytes are abundant. There is marked macrocytosis—the number of small sized red corpuscles is striking and these vary in size and shape (anisocytosis). Misshapen red corpuscles (poikilocytosis) are abundant. The high color index (high hemoglobin value of the individual cell) is one of the con- stant features and serves in doubtful cases to make diagnosis and prog- nosis positive. Polychromasia is the rule. Normoblasts or nucleated 522 DISEASES OF BLOOD AFD HEMOPOIETIC ORGANS red blood corpuscles are usually, but not always present. During the early history of individual cases (not acute or rapidly fatal) normoblasts are present. Their presence indicates response of the bone marrow to the stimulation necessary to make new blood elements. The complete ab- sence of nucleated red corpuscles may be interpreted as indicating failure to respond and is always of bad prognostic significance. The myelogenic reaction which brands an anemia as pernicious and consequently fatal is of great importance. Xeusser says “We find the expression of reaction of the bone marrow, which is regenerative, in the appearance of nucle- ated red blood corpuscles (normoblasts) while the production of megalo- blasts with degenerated small and badly tinged nuclei are the expression of degeneration.” The leukocytic count in the average case may not be materially changed but as the disease advances there is a reversion of the entire blood to the embryonic state. The presence of myeloblasts in increased numbers (5 to 10 per cent) is not unusual and blood platelets may drop to 75,000-100,000. In our consideration of the subject we assume that pernicious anemia because of its uncertain pathogenesis should include “any profound and (apparently) causeless anemia which is characterized by peculiar altera- tions in the blood—which tend to pursue a progressive and pernicious course.” (Bramwell.) Bramwell believes that the question whether the clinical condition termed pernicious anemia “may result from a variety of causes or whether it is a singular clinical entity, the causation of which is always one and the same, should be left an open one.” We are safe in concluding that in the typical cases there is excessive and rapid blood destruction (hemolysis) and defective blood formation. For our purposes of prognosis the consideration of the unsettled the- ories relating to the etiology of the disease is unnecessary. Indeed the profession is by no means agreed. There are data both clinical and ex- perimental which strengthen the infectious and toxic origin of the dis- ease, that increased destruction of blood in the portal system is due to the absorption of toxins from the gastro-intestinal tract, and that oral sepsis (Hunter, Wm.) is an important factor in causation. In considering various pathologic data wdiich influence prognosis the frequency of achylia gastrica (Einhorn 1892—Martins 1897) associated as it is with atrophy of the gastric follicles, a frequent, almost constant attendant deserves consideration (Grawitz, Fenwick, Quincke, Nothnagel, Jurgens, Friedenwald). While Friedenwald does not subscribe to Gra- witz’s contentions that with achylia gastrica resulting toxemia, the hemo- lytic action of toxins elaborated in the stomach and intestines cause perni- cious anemia; he found in 70 per cent of his pernicious anemias the pres- ence of atrophy of the gastric follicles (achylia gastrica) and in 20 per cent of the remnant marked reduction of hydrochloric acid. Friedenwald ANEMIA 523 believes that the same toxic agent is at once the cause of the achylia gas- trica and the pernicious anemia. Lazarus expresses the same view, believing that both conditions are the result of an unknown poison. Faber and Bloch believe that the changes in the gastro-intestinal tract are post mortem and that there is no direct proof of the existence of such lesion intra vitam. This contention has not received support. We know that during life in most cases there is absence of free hydrochloric acid and we have often in our cases found long periods of improvement or latency follow the administration of free HC1. in large doses after the method of Croftan. Whatever we conclude concerning the relation of achylia gastrica and essential anemia the fact remains that life is shortened by the complete anorexia and gastro-intestinal disturbances associated with atrophy of the gastric and intestinal glands. We have seen the more rapidly fatal course in those cases in which after a period of intestinal symptoms, diarrhea) usually, hemolysis has been rapid, the general condition has promptly failed, complete anorexia and stomach intolerence has been marked and without remission, but with increasing involvement of the sensorium death has followed. There are a number of cases in which during years pre- ceding the development of essential anemia, chronic diarrhea has been a prominent feature. This remains uncontrolled in most cases and finally, there are added the complete blood picture and other clinical features of pernicious anemia. These patients are not likely to have periods of remis- sion or latency, but the onward march to death is prompt, with symptoms of sepsis. Pernicious anemics without prominent and persistent gastro-intestinal symptoms live longer and are more likely to have periods of remission and latency than do those with such complications. Grawitz who bases his pathogenesis on the absence of free hydrochloric acid in the stomach contents reports repeated cures. Critics are agreed that none of the cured cases have been proved to be true pernicious anemia. Grawitz does not consider the blood picture of pernicious anemia diagnos- tic and has, according to Tiirk, included all forms in his list of the essen- tial anemias. Lazarus, Cabot, Tiirk and FTaegeli disagree with Grawitz and believe that cases of primary hemolytic anemia in which there is a characteristic blood picture and in which there are positive evidences of the failure of the bone marrow to react to normal stimuli, are fatal. Pernicious Anemia and the Spleen as a Hemolytic Organ.—The suc- cessful issue in Banti’s Disease in which there are evidences of anemia and hemolysis which have followed splenectomy with the results of experi- mental research, have led a number of clinicians to consider the influence of splenectomy on the prognosis of pernicious anemia. The literature of this subject is growing and while in a few individual eases thus treated 524 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS patients have withstood the operation, no positive conclusions are justified at the present time. Eppinger reports two cases of pernicious anemia with- out death following the operation. He believes that the extirpated spleens of pernicious anemia, hemolytic jaundice, and experimental toluylendia- min are identical, all filled with erythrocytes. The urobilin in the stools of all splenectomized patients showed marked reduction and convalescence was without incident. Eppinger’s material besides the two cases of pernicious anemia included 2 of hemolytic jaundice, 3 of Banti’s disease, 2 of hypertrophic cirrhosis and one of grave catarrhal icterus. There are isolated cases in medical literature in which there seemed to he improvement but we are not justified in reporting any cured. We would further refer the reader to the reports of George Klemperer and Hirschfeld, Banti and the experimental work done by both American and German pathologists in this field. Acute Pernicious Anemia.—There are cases in which pernicious ane- mia runs a rapid course to a fatal termination; such behavior is excep- tional. I have recently seen a case in which, after a short period of indefinite “Lichtheim symptoms” within two weeks there was such prompt hemolysis and utter loss of marrow reaction that the blood picture of the gravest megaloblastic anemia was complete. There are cases of syphilitic anemia which we have met in families with positive hereditary tendency to pernicious anemia, in which the blood picture of the disease is completed within a few weeks. Such a case I now have under observation in which one parent and one brother died of pernicious anemia; a sister suddenly developed the cord symptoms which are often present early in the grave types of the disease, the hemolysis was most destructive, the count fell to almost 1,000,000 within two weeks, the cell elements and high color index were characteristic of true essential and pernicious ane- mia. The intravenous injections of neosalvarsan promptly brought relief of both objective and subjective symptoms. Such cases, before a positive prognosis can be given, demand long periods of observation for it is not at all safe to conclude even in the acute cases with positive Wassermann reaction and the blood picture of genuine pernicious anemia that the treat- ment has not proved sufficient to awaken the bone marrow to renewed activity and that later there will not be a return of classic symptoms and the onward march of the disease. Certainly the syphilitic history and the satisfactory reaction following salvarsan in acute cases argue in favor of a good prognosis in cases of grave anemia which in the end, if the patient remains permanently cured, proved that they were not true megalo- blastic anemia. With acute pernicious anemia marked glossitis, gastro-intestinal symp- toms, rapid loss of strength, dyspnea and symptoms referable to the cenr tral nervous system, (brain particularly) the chances of remission are small and death may be expected before the end of the eighth week. ANEMIA 525 While the sudden, severe and 'persistent character of blood destruction —hemolysis—is the feature which is in the ascendency even in acute cases, the striking power of regeneration is a factor which is paramount and it does in a proportion of cases, which begin with acute symptoms and rapid blood destruction (in the more favorable cases), lead to marked improve- ment, long periods of remission and the restoration of sufficient strength to return the patient to his work. Such patients may remain immune from symptoms during varying periods in spite of the acute onset and enormous hemolysis, but in the end the symptoms return; there may be several remissions but the end follows a period of continuous symptoms just as in those cases which were chronic and progressive from the begin- ning. Remissions and Periods of Latency.—Nature’s attempt to stimulate the blood producing organs to renewed activity after hemolysis is strik- ingly successful in over 50 per cent of all cases. Indeed it is the excep- tion to find an idiopathic anemia which leads to a fatal termination with- out one or more remissions of varying length. Cabot reports 524 cases of which 296 had one remission 118 “ two remissions 65 “ three remissions 21 “ four remissions 24 “ five remissions In 6,300 cases of internal disease tabulated, I have seen 46 cases of pernicious anemia, in over 15 per cent of these, remissions led to such marked improvement as to materially change the blood picture and not infrequently the original diagnosis has been doubted. I number among my older cases one of a young girl in whom I made the diagnosis from the positive blood picture 10 years ago, who improved and married, indeed the blood apparently became normal until within the past six months, when she returned after a short period of severe Lichtheim symptoms with a blood count of 1,510,000 erythrocytes; 7,800 white corpuscles, color index 1 + and the disease is now rapidly progressive. This case had the longest period of remission of any case in my experi- ence. It proves that it is not safe to offer rose colored prognosis in these cases. I have never met true pernicious anemia, it matters not how long the period of improvement or remission, which did not finally lapse. The length of life depends upon the natural powers of recovery of the blood producing organs which as Hunter has said, “are very striking and constant,” as well as upon the complications. I would warn against the assumption that any particular form of medical treatment is the paramount factor in stimulating the inherent power of the bone marrow to regenerative function after even long periods 526 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS of inactivity. It would seem that when hemolysis has produced the char- acteristic degenerative changes the bone marrow attempts to come to the rescue and as already suggested succeeds during varying periods. Bramwell reports that one of his patients remained well for 12 years and then relapsed and died almost fourteen years after the first attack. Nervous Symptoms.—I have repeatedly referred to “Lichtheim symptoms” in considering prognosis. These include a variety of subjective complaints, the leading early symptoms are a “numbness and awkward- ness of the hands” often the legs are paresthetic at the same time. These paresthesias and accompanying reactions are often “tabetic” in charac- ter and include unsteadiness of gait and loss of patella tendon reflex. In rare cases pupillary changes are present as well as sphincter disturbances. It is interesting to note that paresthesias and disturbances of locomotion at times antedate anemia. In another group of Lichtheim cases there may be hut slight paresthesia of the hands early, no tabetic symptoms, in which the nervous complex increased with progression of the anemia. There are, in the most severe cases, in which remission is scarcely to he expected, early evidences of cerebral toxemia, from which the patient may only partially rally to finally fall into profound coma. Such behavior is unusual, characterizes the terminal stage, hut whenever there are profound mental disturbances the prognosis for life is had and death promptly fol- lows. While the gravity of the anemia is not in direct proportion to the nervous symptoms in all cases, our experiences justify the conclusion that once established, Lichtheim symptoms are likely to persist and that marked tabetic and cerebral symptoms when present are found in the most advanced stages or in those cases least likely to have long periods of remission. When remission is decided in cases with few Lichtheim symptoms the slight numbness and other abnormal sensations are usually borne without com- plaint. In my 46 cases of pernicious anemia among 6,300 patients over 80 per cent developed Lichtheim symptoms either early or late—usually during the first 12 months of the disease. Heart and Blood Vessels.—With the initial hemolysis the pulse is small, thready and rapid with a low blood pressure and a strong tendency to edema of the ankles. When the edema becomes general the myocardium is enfeebled and there is hydremia in most cases. Small, feeble, rapid pulse, low blood count, dyspnea, edema and evidences of toxemia showing themselves in increasing mental and nervous disturbances, form a complex which with the blood picture is characteristic of the terminal stage of the disease. Small feeble pulse with tinnitus aurium, vertigo and palpitation with some Lichtheim symptoms and low red count may still be followed by remissions, one or more. Edema of the lung with feeble heart and other complications, marked enlargement of the liver and albuminuria are unfa- vorable, and soon lead to death. Persistent tricuspid regurgitation, epistaxis and purpura are unfavor- ANEMIA 527 able. Usually there is marked edema, at times hydrothorax and retinal hemorrhage. Venous hum over the neck veins (external jugular) may be present early and persists during the periods of exacerbation until the end; the same is true also of hemic murmurs heard best at the base of the hearu With an improved blood these murmurs may disappear. Retinal hemorrhages may be an early or late complication. Probably 50 per cent of essential anemias have retinal hemorrhage at some time. The hemorrhages are not, as a rule, large. I have never seen a case in which the hemorrhage led to blindness. Retinal hemorrhage and pallor of the fundus are of diagnostic and prognostic value. Deep purpuric con- ditions once present, there is small hope of remission or improvement of the blood state. Temperature.—Slight elevation of temperature is frequent. Some cases have a continuous slight elevation of temperature which does not seem to interfere materially with the disease. In most cases the higher con- tinuous fever which is associated with other toxic symptoms—central nerv- ous manifestations—is present late in the disease and is not influenced by treatment. The fever is almost always irregular and atypical. It is an expression of toxemia. In chronic cases death is often hastened by acute exacerbations during which elevation of temperature is the earliest symptom. Such cases may be following a typical course, with periods of remissions, when without known cause, there may or may not be a chill; continued fever, not always high, but with a slight morning fall persists. With increasing malaise and extreme exhaustion and increasingly rapid and small pulse, symptoms of toxemia including delirium and coma follow. The temperature curve is between 100|° F. and 103° F. (may be higher). Death may be ex- pected before the end of the fourth week. The mental (toxic) symptoms are always prominent from the beginning of such exacerbations. The urine offers no marked features to influence prognosis. Cases which show no tendency to improve may often die without showing a trace of albumin. In other cases as already suggested, with general dropsy in the terminal stage, albuminuria is present. High colored urine with uro- bilinuria is often an expression of blood destruction (blood crisis) and unfavorable. Indicanuria is of no prognostic value in pernicious anemia; it is not unusual. Tongue.—“Oral sepsis'” has been strongly advocated by Hunter as be- ing of great importance and provocative of pernicious anemia; the same author believes that with relief of the septic element, the blood picture and the general condition of the patient improves. There are in some cases from the beginning marked changes in the tongue which are best consid- ered to be inflammatory, atrophic, at times ulcerative. Glossitis is by no means a constant attendant of pernicious anemia. In 528 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS the late stages the shining, wrinkled, dry, often cracked and bleeding tongue is present. In all cases the tongue is pale. Marked evidences of dry tongue—the glazed, shining denuded tongue with ulcerative gingivitis and bleeding gums are evidences of malignancy of the anemia and indicate advanced disease. Atrophy of the gastro-intestinal glands with glossitis and correspond- ingly low blood state are not often followed by long or satisfactory remis- sions. Retention of the body weight, fat particularly, does not in any way influence prognosis. Cachexia is not frequent or striking. The marked anemia is out of all proportion to the cachexia or loss of weight, while as already suggested with malignant disease, the cachexia is out of proportion to the anemia (Henry). Intravenous and intramuscular injections of salvarsan, intensively used have been advocated by many during the past 3 or 4 years. Personally, after a reasonably large experience with the remedy we are unable to positively say that a single case has been saved. In the graver specific anemia it does yeoman service. In those cases of pernicious anemia in which it has seemed to have a wholesome effect in stimulating the blood producing organs and improvement has resulted, there is no assurance that relapse may not follow. Indeed the improvement when it does fol- low is usually short-lived. Bramwell in a recent article in which he reports his results of 21 cases treated by salvarsan and neosalvarsan had “6 without improvement (28.5 per cent) ; in 3 (14.2 per cent) there was slight improvement; in 5 (23.8 per cent) there was marked improvement and in 7 (33.3 per cent) there was complete ( ? temporary) recovery. Ultimate results of BramwelPs series show “of 21 cases treated by salvarsan or neosalvarsan and recorded in this paper, in 1 case (4.7 per cent) the patient remains fairly well; in 5 cases (23.8 per cent) quite well; in 15 cases (71.4 per cent) the patients have died.” Such statistics are of no practical value. They are too recent and in- definite. Bramwell correctly states the case as follows: “In order to judge fairly and accurately of its value, a series of consecutive and unselected cases, slight as well as severe, in which no other treatment has been employed, should be taken and the results compared with a series of similar cases treated by other methods.” The great majority die in coma, after a period of brain symptoms vary- ing from two to four or more weeks. Complications are exceedingly rare. Occasionally bronchopneumonia or added infection causes death, not often. Pernicious anemia with atrophy of the gastric follicles and tuberculosis of the suprarenals (including bronzed skin) were found in one of our cases ANEMIA 529 References Addison. London Med.

Leukocytic or Splenomyelogenous Leukemia The original description of leukemia with the clinical and blood pic- tures given by Virchow was so exact that but little which has been offered since has materially altered his original conception of the disease. Eb- stein, who has made a careful investigation unhesitatingly concludes that Virchow recognized the disease before Bennett to whom the credit is usu- ally given. The references appended make it possible for the student of medical history to study that question for himself if he desires from the literature within easy reach. Virchow did not appreciate the part played by the bone marrow until Neumann, in 1870, called attention to it. Leu- kemia may he defined as a condition of the blood in which the white blood corpuscles are enormously increased so as to be in the proportion of 1 to 20 of the red cells or there may be greater disproportion (1-10 or 1-5), in which there are changed relations of the normal varieties and numbers of white blood corpuscles depending on a specific cause (unknown) and irritative growth in the blood producing tissues (hyperplasia of the leuko- blastic tissues) which result in the flooding of the blood with either myelo- cytes or lymphocytes, in accordance with the variety of leukemia present. The true nature of the disease is unknown. Some believe it resembles or is closely related to sarcoma and myeloma. Leukocytic or Splenomyelogenous Leukemia Blood.—The myelocytes, large mononuclear cells of Ehrlich, are in the ascendency and are supposed to differ from the large mononuclear LEUKEMIA 531 lymphocyte. All blood, therefore, which contains myelocytes is abnor- mal. The myelocyte is normally present in the bone marrow. In leuko- cytic leukemia there is an overdevelopment of the myelocytes and their casting off into the blood stream. Relatively the proportion of the polymorphonuclear cells is decreased. They are actually increased. There are many polymorphonuclear leuko- cytes, a preponderance of myelocytes, eosinophils and eosinophilic myelo- cytes; increased mast cells; an occasional normoblast; poikilocytes, inegalo- cytes, microcytes, pale red blood corpuscles, and in advanced cases Char- cot-Leyden crystals. The alkalinity of the blood is decreased; the specific gravity reduced (1,025-1,040); there is finally a positive reduction of hemoglobin (average early 60 per cent lower as the disease advances). Bennett characterized the disease as “suppuration of the blood.” A high myelocytic count, irrespective of the number of leukocytes is essential for the diagnosis of splenomyelogenous leukemia, just as megalo- blasts are necessary for the diagnosis of pernicious anemia. The average white count in our series at the height of the disease was between 275,000 and 300,000. We have, in rapidly fatal cases made counts much higher. In one case seen many years ago with marked hemorrhagic tendencies in the terminal stage, the red and white counts during the last few weeks of life ran practically parallel—500,000 to 800,000 per c. mm. The poly- morphonuclear cells average between 25 and 50 to 55 per cent; the myelo- cytes from 30 to 50 per cent. Almost all of our cases were without hered- itary taint—with the male decidedly in the ascendency. In some cases the red count may remain normal or nearly so for a considerable period, rapid or progressive drop of erythrocytes is unfavor- able, particularly if at the same time, there are evidences of increasing ex- haustion, hemorrhages, purpura or increasing mental symptoms. Marked morphologic change in red corpuscles with increasing hemolysis is unfa- vorable for the prolongation of life. High fever, or even continuous elevation of temperature, slightly above 100° F. with evening rise, is evidence of advancing change and unfavorable for prolongation of life. Symptoms referable to the nervous system often resemble the Lichtheim complex of pernicious anemia. The greater the involvement of the nervous system the shorter is the course of the disease, as a rule. Invasion of the sensorium is indicative of deep toxemia or in- filtrating changes in the brain and is promptly followed by death. There is greater paresthesia than tabetic symptoms though the latter may be present, also neuritis. Tinnitus aurium and vertigo are evidences of pro- found anemia in most cases. Hemorrhages into the auditory system lead- ing to deafness and uncontrollable vertigo are unfavorable symptoms. The spleen is enormously increased in size. In some cases in which, as the result of treatment or nature’s processes, the white count improves, the splenomegaly shows some retraction, but this is not to be relied upon 532 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS as occurring uniformly. In my cases treated with Rontgen Rays and Benzol, the spleen did not change in size with the improved blood .picture. Perisplenitis has not been a frequent source of pain in my cases. It has no great bearing on the progress of the disease. I have never met a death due to rupture of the spleen in my material, occasional cases have been reported in which rupture was the cause of death. Marked dyspnea, cough, expectoration and physical signs of infiltration are indications of advancing disease. Dyspnea and cough may be due either to leukemic in- filtration of the lung or myocardium or to extreme weakness and myocar- dial weakness. The physical signs of infiltration of the lung may also be due to complicating tuberculosis. These cases all progress rapidly to a fatal issue. We consider elsewhere the influence of added tuberculous in- fection on the white blood count. Dyspnea and respiratory embarrass- ment may also be due to pressure from hydrothorax, hydropericardium, en- larged spleen and liver. The prognosis is unfavorably influenced by gas- tro-intestinal complications or symptoms. In severe cases, often in the last stage, anorexia, vomiting and diarrhea, with hemorrhage, rapidly weaken the patient. In the terminal stages ascites and general edema are in evidence. It may happen that after the removal of the abdominal fluid toxic symptoms increase. At times life may be prolonged during a short time by such procedure. With fbrotic and nodular changes in the liver and fatty de- generation, or the latter alone, there may be slight jaundice. The liver as suggested elsewhere in this section may show leukemic infiltration. All of these conditions are unfavorable for the prolongation of life. Peri- tonitis is the terminal complication in rare cases. The urine shows an increase of uric acid (characteristic condition) ; there may be moderate albuminuria, hyalin casts and evidences of acute or chronic nephritis. In some cases barring the excess of uric acid, even in severe cases, there are no changes in the urine. Occasionally the urine is of a greenish hue and Bence-Jones albumose has been present as in multiple myeloma (Kahler’s Disease). Such complications are most fre- quent with lymphatic leukemia. I have seen several examples of priapism which has persisted unre- lieved by any treatment. In one woman, the clitoris was in a state of chronic erection and with vaginal irritation caused great discomfort. The behavior of the heart is much like pernicious anemia as the end approaches. From the beginning of symptoms there is rapid action, small and thready pulse, systolic blood pressure is low. As the disease advances the systolic force grows more and more feeble, the heart sounds embryonic and dilatation with hemic murmurs, jugular pulsation, tricuspid insuffi- ciency and frequent syncope may precede death. Pulmonary edema due to heart insufficiency is a cause of death. Early or late, usually late, evidences of hemorrhagic retinitis are in evidence with LEUKEMIA 533 associated ocular subjective symptoms. Sight is not lost; optic neuritis is not frequent. 2, Lymphatic Leukemia {Lymphemia, Leukocythemia, Chloroleukemia, Pseudoleukemia) The essential features of lymphatic leukemia are changes in the lym- phatic glands of the body causing multiple enlargements (increase of lym- phocytic forming tissue) and the resulting lymphocytosis. The blood changes are characteristic. Blood.—The color index is low, the hemoglobin reduced, the coagula- bility, alkalinity and specific gravity are much like the splenomyelogenous form. There is true lymphemia, The small lymphocytes are in the as- cendency. There is increase in the number of polymorphonuclear leuko- cytes, though less than in leukocytic leukemia. The red blood corpuscles usually number 3,000,000 or below, as the disease advances. Few nucle- ated red cells are seen, less than in the other variety of the disease; a few myelocytes and a small fraction of eosinophils. In both varieties of leu- kemia the blood platelets are increased. The lymphatic type shows a predilection for children and young adults, though older subjects may develop the disease. Males are more frequently afflicted than females. The lymphatic enlargements may at first be limited, beginning in the neck, and extending to the axilla with, in advanced cases, multiple enlarge- ment in the glands of the body—mediastinal, postperitoneal, mesenteric and inguinal. There are also changes in the internal organs due to infil- tration. The spleen may not be materially enlarged. The anemia is slower to develop in this form than with myelogenous leukemia. In some cases the color may remain good in spite of mulitple lymphatic enlargements. The fever is not likely to be an early symptom. It is often long postponed. Skin pigmentation and nodules are relatively frequent. The involve- ment of the oral mucosa, teeth, tonsils and postnasal glandular tissue, in- creases septic symptoms and hastens the end. Chloroma is a condition of lymphemia with nodules in the skull, green color of the lesions as the glandular structure proliferates, the presence of exophthalmos and facial paralysis in most cases. Chloroma may be asso- ciated with or is a part of either myelogenous or lymphatic leukemia, usu- ally as above stated the latter. It may be associated with the acute or chronic leukemias, usually the former, but cases have been reported which lived from two to four years (Ward). The average duration of life is below seven months. 534 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS 3. Acute Leukemia (Ebstein) Acute leukemia may be either leukocytic or lymphatic. The large majority of cases are typically lymphatic, though the spleuomyelogenous form is occasionally met (Naunyn). In the latter form we have seen two cases which commenced suddenly without prodromata, with high fever fol- lowing repeated chills. The spleen and liver were enlarged at once, the former was somewhat tender. One of these was a girl about 15 years of age who during several months was favorably influenced by Rontgen ther- apy, indeed the high leukocytic count was at once reduced and after a few weeks her physician reported counts approaching leukopenia, when her fever and chills were under control. So striking was the improvement that the case was reported at the meeting of the Medical Society of the State of New York by her attendant, who wTas much encouraged by the result. (Schuyler.) The improvement was short-lived. She died as did all other cases. The typical cases of acute leukemia begin suddenly with marked febrile disturbances, the lymphatics are involved, there is lymphemia and increas- ing anemia. Fraenkel has reported the constant presence of abnormally large mononuclear cells, wasting and toxic symptoms, enormous prostra- tion, hemorrhages from the mucous surfaces and purpura, (skin) and the enlarged spleen are among the symptoms. The blood changes are exceedingly rapid. Death results in coma after a period of typhoid condition in from four weelcs to three or four months. Russell and Taylor have reported 55 cases of acute leukemia. We have never known of recovery. Cases in which there is depleting diarrhea die early. Ulcerative colitis and enteritis have accompanied some acute leu- kemias. Thymus and tonsillar infiltration, gingivitis (ulcerative) and ulceration of the buccal mucosa lead to inanition and early death. Rapid leukemic infiltration of vital organs, lung, liver, and kidney with skin nodules—pigmentation and leukoderma are found in both forms of acute leukemia. The more extensive the leukemic nodules, the sooner will death follow. The brain may be the seat of infiltration causing hemorrhage with resulting paralysis and other focal symptoms. Hemiplegia has been re- ported as well as ocular and aural lesions with consecutive symptoms. There are occasional cases reported in which decided increase of lympho- cytes has failed to appear until within one or two weaks of death. (Litten, Waldstein, Villinger.) The majority of acute leukemias are found in children and before the age of 20 years. 4. Leukanemia (Leube) Leube called attention to blood changes and a clinical history in which there are evidences of myelogenous or lymphatic leukemia with grave LEUKEMIA 535 anemia. The lesions present depend upon the variety of leukemia with which the grave anemia is associated. The prognosis is bad. 5. Mixed Leukemia There are also mixed forms of leukemia in which the blood picture shows cellular elements characteristic of both forms of the disease. The influence of treatment on the prognosis of all forms of leukemia has not been encouraging. Beginning with x-ray therapy and ending with benzol and mesothorium, enthusiasts have been deluded by the surpris- ing influence of the Rontgen Ray over the long bones and spleen, and the benzol internally administered in reducing the leukocytic count. Periods of improvement of subjective symptoms have followed but we have no record at hand after wading through a large literature hearing on the sub- ject which justifies the conclusion that a single case has been permanently benefited. All relapse and all leave died. There is great danger from the sudden and overpowering poisoning due to the destruction of large num- hers of leukocytes following the Rontgen Ray and the use of benzol. The influence of splenectomy on leukemia is being considered, hut in spite of a few reported cures (?) there are no data at hand which warrant the conclusion that the “cured” were veritable cases of the disease. Until we are better informed by experimental study on the influence of the spleen in these cases, no hope is justified by the removal of that organ. The aver- age duration of life in uncomplicated cases is between six to eight months and between three and five years. My lymphatic cases have lived longer than the myelogenous. Remissions with considerable periods of improvement are character- istic, but not so strikingly frequent as in pernicious anemia. Many spleno- myelogenous leukemias are progressive from the beginning without a stay of symptoms, either subjective or objective. Lymphatic leukemia frequently shows tendency to remain latent dur- ing long periods. Once symptoms of deep toxemia show themselves or with purpuric or hemorrhagic complications, with acute exacerbations and high temperature, edema, ascites or other evidences of dropsy, heart degenera- tion, remission cannot be expected. The subjective symptoms of all forms of leukemia have practically the same influence on the forecast. Complications.—The influence of acute or chronic added infection upon the blood count is striking. I called attention to the influence of added tuberculosis in connection with Groat in a case of splenomyelogenous leukemia. With tuberculous infiltration of the lung and its advance, the myelocytic count was promptly reduced (Eisner and Groat, also George Dock). These observations have been confirmed by other observers in con- nection with a variety of complicating infections. There are but few com- plications. Death results from asthenia in coma, in most cases. Pulmo- 536 DISEASES OF BLOOD AND HEMOPOIETIC OKGANS nary edema, bronchopneumonia, exhaustion following hemorrhages and sudden syncope are among the causes of death. In all forms of leukemia the greater the number of leukemic nodules in the internal organs and skin, the more rapid is the course of the disease. Bennett {I. H.).

Hodgkin’s Disease Lymphoblastoma {Pseudoleukemia, Lymphadenoma, Malignant Granuloma, Adenie, Lymphogranuloma) Hodgkin’s Disease is characterized by marked enlargement of the lymphatic glands of the body, beginning, as a rule, in the cervical region and extending to distant parts (axillary, mediastinal, bronchial, mesen- teric and inguinal) with more or less enlargement of the spleen and liver .as the disease advances and finally the blood picture of grave secondary anemia. To sum up and contract the definition, Hodgkin’s Disease may HODGKIN’S DISEASE; LYMPHOBLASTOMA 537 be considered a far-reaching disease of the organs which elaborate blood cells, including the lymphnodes, the spleen and bone marrow, which bears external resemblances to leukemia but is without the typical leukemic blood picture (Naegeli). The disease bears close resemblance to tuberculosis without the pa- thologic changes which prove it to be of bacillary origin, while there are some features which resemble the leukemias, which led pathologists to name it “pseudoleukemia.” The entire history of the disease, its symp- tomatology and pathology create a strong suspicion of the presence of an infectious agent. Within the last few years this suspicion has been strengthened by the experimental and pathologic researches of various men, foremost among these are Bunting and Yates who, as the result of their studies are strongly of the opinion that the diphtheroid organism which they have cultivated from cases of the disease in man and with which they have successfully inoculated monkeys, reproducing lesions similar to those of the disease in man, will ultimately prove its infectious nature. They say “we feel fully assured of the etiologic relationship of the diphtheroid organism (Bacterium Hodgkini) to Hodgkin’s Disease.” The early and tonsillar and alveolar symptoms in many cases create the further suspicion of infection and point strongly to the tonsils (teeth and mouth) as the port of entry. Hodgkin’s Disease may be accepted as a clinical entity in which the pathologic changes in the lymph glands are characteristic and include marked increase of the gland tissue, multiplication of the endothelial and reticular cells and as has been shown (Andrewes and Dorothy Reed) lymphoid cells are enormously increased and are of uniform size and shape; giant cells, the lymphadenoma cells, hold multiple nuclei; while eosinophils are constantly present. The hardness of the gland is due to the fibroid change—reticular increase. Suppuration is rare, and when this happens, there is in all probability added pyogenic infection. In some of the monkeys inoculated by Bunting and Yates, the “softening” was found, but without the presence of any added microorganism. The Bacterium Hodgkini alone grew in the cultures of these cases. [The study of the life of Hodgkin who in 1832 described the disease which bears his name, proves him to have been one of the three clinical and pathological giants of the early half of the nineteenth century who added fame to Guy’s Hospital. The other two were Addison and Bright. (Stroud, Wm.) Hodgkin deserves to be remembered not only as having made clear the clinical and pathologic characters of the disease bearing his name but as an unselfish and humane physician.] Haegeli considers Hodgkin’s Disease or pseudoleukemia a symptom complex of these diseases: A. Lymphocytoma.—Lymphocytoma, or those in which there is pro- liferation which he characterizes as lymphocytic and aleukemic, in which 538 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS the lymphatic system is largely involved, in which the spleen, bone mar- row, liver or periosteum may, in individual cases present the greater changes during varying periods. Included in the lymphocytoma are: (a) The Aleukemic Lymphadenomata (Hodgkin’s Disease of most clinicians). (b) Lymphosarcomatosis (Kundrat’s Disease). These are localized sarcomata originating in lymphatic tissue (lymph nodes usually), never disseminated beyond the lymphatic system. Liver and spleen are not enlarged. B. Granuloma.—The granulomata are inflammatory growths and not true Hodgkin’s Disease, they may be: (a) Malignant. (b) Tuberculous. (c) Syphilitic. When, therefore, we consider “Hodgkin s Disease” we include the lymphocytomata or the aleukemic lymphadenoma. The course of Hodgkin’s Disease may be either (a) acute or (b) chronic: (a) Acute Hodgkin’s Disease.—The acute form of the disease usually begins with tonsillar symptoms which resemble very closely the sub- jective features of acute leukemia. The advance of lymphatic inva- sion with associated constitutional disturbances, changes in the spleen, thymus and blood are often surprisingly rapid and ultimately fatal. In most of these cases there is fever, often marked hyperpyrexia with prompt emaciation, cachexia, and toxic symptoms (cerebral). In several of our cases, with slight enlargement of the spleen and liver, there has been edema of the extremities, purpuric spots over the body and deplet-> ing epistaxis. These cases are to be differentiated from the typical acute or subacute relapsing cases described by Pel and Ebstein. The non- relapsing acute Hodgkin’s Disease is always fatal and runs its course in from three weeks to as many months. The Hodgkin’s process of Pel and Ebstein may continue during many months. In this form of the disease the symptoms often resemble the more acute type but there are varying periods of relapse (7 to 14 days) after high and weakening fever, with excessive sweats, wasting and increasing secondary anemia. There may be enlargements alone of the internal glands, or as we have seen in sev- eral hospital cases, the lymphatic invasion is general and one of our cases died with mediastinal pressure of asphyxia which increased suddenly. In the Ebstein pseudoleukemia the temperature during the afebrile period may be subnormal from which there is a gradual rise to the climax. In one of our cases there was, at the beginning of each relapse, a well defined chill during which the temperature reached 104-5° E.. where it HODGKIN’S DISEASE; LYMPHOBLASTOMA 539 remained much of the time for three or four days, when it fell gradually to below normal. These patients may develop purpuric symptoms, have hemorrhages, fall into a typhoid condition; usually have evidences of nephritis with the blood picture of secondary anemia. Ziegler called attention to cases in which there are constitutional symptoms, elevation of temperature and increasing evidences of anemia without palpable external glandular enlargement, but involvement of the internal glands. The spleen is usually enlarged in these cases, and it has been suspected that occasionally the disease originates in the lym- phatic structure of the spleen. In some cases the retroperitoneal glands alone may be involved, in others the bronchial or both thoracic and abdominal glands may be enlarged at the same time. These are con- sidered under the head of the “Latent type.” We know of no recovery from a single well authenticated case of these types of the acute disease. Heffron’s case presented a typical history in which mediastinal pressure promptly caused death. Such cases are not infrequent. For the full study of the symptomatology of the relapsing type of Pel-Ebstein the reader is referred to McNally’s paper (See References). (b) Chronic Hodgkin’s Disease.—The onward march of the disease is slow, the first evidences are the enlargement of the cervical glands, usually one sided, at the angle of the jaw. The extension to the opposite side may be long postponed but careful examination in most cases will detect an abnormal hardness and some enlargement of one or more deep cervical glands long before the growth extends to the other side of the neck. The enlargement of the lymphatics may be surprisingly extensive as the disease advances and multiple skin nodules are not uncommon. A recent case showed extensive bronzing of the skin—probable involvement of the suprarenals. This man in spite of the existence of the disease during several years (3) and glandular enlargements in all possible direc- tions, palpable spleen and liver, with a blood count with all the charac- teristics of moderate secondary anemia and albuminuria, was able to work his farm and walked without discomfort. When the mediastinal glands are involved the pressure symptoms are persistent and increase; the suffering is acute and with edema of the face and arms, or at times with only symptoms of compression death promptly follows. The blood picture is not pathognomonic. As already intimated Hodgkin’s Disease in the chronic type leads to blood changes which cor- respond with those of secondary anemia (anemia gravis). There are eases in which the glandular enlargements are prominent without dis- coverable changes in the blood. These are among the most chronic cases; life is not threatened during long periods unless death is caused by pressure or other complications. In the average case the leukocytic count is not markedly increased. Even in the acute cases this rule holds and 540 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS makes differential diagnosis easy. In some, particularly during febrile exacerbations, there is moderate leukocytosis (10,000-30,000). Lympho- cytes may be increased with the fall of polymorphonuclear cells. In these cases they may represent 75 per cent of all white cells. Pinkus holds that the relative lymphocytosis is typical of the disease. Bunting believes that tbe diagnosis can “be made with a considerable degree of accuracy” from the blood picture, and does not agree with Pinkus that lymphocytosi': is typical. It may be safely concluded that the more chronic and serious cases show the greater changes in the blood, anemia and some leukocytosis. The “two constant features” which Bunting holds for diagnosis and therefore for prognostic data, “an increase in blood platelets and an absolute increase in the transitional leukocytes,” cannot be accepted in all cases. We are agreed that the majority of late cases show marked neutrophilic leukocytosis “and a diminution in per- centage of all other elements except the transitional leukocyte.” There are cases (ISTaegeli and Baumler) in which the lymphocytes are markedly reduced with marked neutrophilic leukocytosis, eosin- ophilia and increase of mast cells. With the cases which have been characterized as “infectious granuloma” the neutrophils continue normal and the lymphocytes are much decreased. Yates who has collaborated with Bunting makes the following state- ment, “In spite of Dr. Bunting’s work, on the blood picture of Hodgkin’s Disease, it is almost universally accepted that there is manifested herein, nothing essentially or constantly characteristic.” In the chronic cases without marked change in the size of the enlarged glands there may be decided remissions. In rare cases the glands appear somewhat reduced, that may have been imaginary. The remission may be due to an im- provement of the periadenitis which is present in some cases. The remissions are not as oft repeated or as long as in pernicious anemia. During periods of remission the appetite improves, the general condition is better and patients are often able to continue at their work. Relapse is the fate of all and progression to a fatal termination. The duration of the chronic cases varies. The average of our cases was in the neighborhood of three years. We have seen cases which lived much longer, one, the longest of our series lived over seven years. Mora- witz reports the possibility of the extension of life beyond ten years in some cases. There is in almost all chronic cases a period which Trousseau char- acterized as the “periode latente,” this with glandular enlargement and no constitutional symptoms may continue during surprisingly long peri- ods; one to three years are the extremes. The “period progressive” is variable; once the symptoms and lesions are prominent and are progres- sive there is not much hope of long periods of remission. The final uperiode cachectique,, of Trousseau is coincident with the terminal stage HODGKIN’S DISEASE; LYMPHOBLASTOMA 541 and from this there is no release. The symptoms of the cachexia are the pallor, weakness, low red blood count, dyspnea, albuminuria, hemor- rhages and purpuric skin changes, bronzing and nodes in the skin, increase of persistent fever, marked enlargements of the spleen and liver, ascites, edema of the extremities, and a period of toxic nervous (brain) symp- toms, with small, thready pulse, hemic murmurs, jugular pulsation and tricuspid insufficiency (relative) at times. Hemorrhagic symptoms are rarely present early; petechiae with or without large hemorrhages from mucous surfaces are ominous. The transition of an original pseudoleukemia to leukemia is possible and occasionally happens. In rare chronic, as in the acute cases, limited lesions—localized forms of the disease may offer but few or indefinite symptoms during long periods; thus the disease may begin in the mesen- teric or postperitoneal glands, be followed by latent periods; extension is sure to follow. The leading causes of death are toxemia, exhaustion, pressure and added infection. Tuberculosis is rarely a complication. The surgical treatment of Hodgkin’s Disease has in my experience been absolutely unsuccessful. On the other hand, it has often seemed to stimulate the growth with extension of lymphatic enlargement. Able clinicians believe that in some cases the progress is halted by early removal. Ho form of treatment—x-ray, surgery, vaccine, serum, drugs, climatic or hygienic, has so far as we have been able to discover, saved a single life. In making the foregoing statement, we are not unmindful of the reported experiences of Yates, who in concluding his article says “. . . even these few cases indicate that primarily Hodgkin’s Disease is a localized process, susceptible of cure wffien properly treated as a malign, though chronic infection. It may persist for years without mani- festing itself save in the blood picture so that cures may not be assumed until after an uninterrupted duration of years of persistently normal conditions.” Syphilitic granuloma offers a favorable prognosis. This is not a true Hodgkin’s process nor are any of the granulomata to be so considered. (See Haegeli’s Classification in this article.) The inflammatory and tuberculous granulomata offer an unfavorable forecast. References Andrews. Transact. Pathol. Soc. of London, 1902, liii, SOB. Baumler. Munch. Med. Wchnschr., 1904, Ifi. Bunting.

Purpura Hemorrhagic Diathesis In considering the prognosis of the symptom complex of purpura we adhere to the following classification which is based upon the hypothesis that the hemorrhagic diathesis includes a variety of symptoms of a large number of heterogeneous diseases (Naegeli) and further that all so-called “primary purpuras” including simple purpura and purpura hemorrhagica, acute or chronic, are all identical, they simply differ from each other in degree and intensity of constitutional symptoms. Classification Purpura -I 1. Secondary. (a) Simplex. (b) Rheumatica (Schoenlein’s disease). (c) Hemorrhagica (Werlhof’s disease) (Morbus maculosus Werlhofi). (d) Chronic purpura. (e) Henoch’s purpura. (f) Hemophilia. 2. Primary 1. Secondary Purpura Secondary purpura as we have demonstrated repeatedly in this work is an expression of a septic or toxic process; symptomatic always of one of many constitutional disturbances and may include scorbutus, hemophilia or the hemorrhagic diathesis. Among the leading conditions with which purpura may he associated are the leukemias, pernicious anemia, Hodgkin’s lymphadenoma, malignant endocarditis, carcinoma, sarcoma, the infec- tions (usually the more severe), vasomotor disturbances associated with nervous disorders, tabes dorsalis, myelitis and hysteria, all cachexias from PURPURA 543 whatever cause and the various intoxications from drugs or other sources (Ergot, belladonna, mercury, iodin and snake bites). Purpura in those with a strong diathesis may follow mechanical insult. Classifying the above causes of secondary purpura into separate groups we find them to be infectious, toxic, cachectic, neurotic and mechanical. (Osier.) The forecast of secondary purpura always depends upon the malignancy or nature of the underlying cause. In all of these conditions the addition of purpura may, if it is extensive, unfavorably influence the progress of the disease, but it should rather be interpreted as an expression of a grave infection or disturbance. (The reader is referred to the separate diseases of which purpura is a symptom for fuller data.) Hemorrhagic scarlet fever and smallpox are examples of malignant infection associated with secondary purpura. Erysipelas offers another example. It may be safely concluded that the grave infections which are “hemor- rhagic(purpuric) at their height, always offer a grave prognosis. This is not always true of purpura which follows the infections, either shortly after the acute symptoms have subsided or later. Severe bleeding from many surfaces may follow typhoid fever and the patient may show marked depletion, secondary anemia. Nevertheless, recovery is the rule under favorable surroundings and rational treatment. The larger hemorrhages with the anemias and leukemias weaken the pa- tient and hasten the course of the disease. With cancer and sarcoma, purpura is almost always included among the terminal symptoms. With myelitis, tabes dorsalis, cerebrospinal menin- gitis and the depleted neglected alcoholic, the downward course is promptly evident after the advent of purpura. Extensive ecchymosis of the genitals in tabetics is a late symptom in the more reduced subjects. In children the administration of iodin in any form (we have found it after even small and continuous doses of syrup of the hydroiodic acid) may cause purpura, hematuria usually, and threatening anemia. With the discontinu- ance of the drug and proper care, the child in the absence of serious pri- mary disease recovers. In the adult with decided hemorrhagic diathesis iodin in small or large doses may cause hemorrhagic purpura. 2. Primary Purpura (a) Purpura Simplex Simple hemorrhage into the skin, without known cause, may he lim- ited or universal and may develop at any age. It is usually found in early life. It is often an expression of reduced vitality and resistance. The malaise anorexia, and (occasional) slight fever which accompanies it, with at times acceleration of the pulse may precede the petechiae several 544 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS days, making positive diagnosis impossible. The subjective symptoms fade in from 3 to 7 days; the hemorrhagic spots show the characteristic changes in color after from 4 to 8 days and appear ecchymotic during two weeks or more. Often these “black and blue” spots persist longer. Purpura simplex bears all of the earmarks of a mild infection from which recovery without complication is the rule without sequelae. The blood picture in most simple purpuras is not materially changed. Occasionally there is a reduction of eosinophils—with convalescence these are promptly increased to the normal. Diarrhea, which is an occasional symptom is easily controlled and is never severe. Purpura fulminans is a malignant type of simple purpura which devel- ops in young infants (3 to 6 weeks old) without known cause, without hemorrhages from the mucous surfaces but with large hemorrhages into the skin, either limited to one extremity or both, or universally spread, with swelling of the parts, deep sepsis and death in from 2 to 7 days. (6) Purpura rheumatica Schoenleins Disease We have found purpura rheumatica, ls£, with symptoms referable to one or more joints (usually the ankles) during several days, without known cause, with but little constitutional disturbance, followed usually on the third or fourth day, sometimes ear- lier, at times later, by petechiae confined as a rule to the skin below the knees, either few or many. In six to ten days the disease ends favorably. The pain is likely to be more or less relieved as the eruption appears. Recovery is complete and without incident. 2nd: Cases in which with the joint tenderness there are evidences of mild tonsillitis, more or less febrile movement and finally the same behav- ior of the petechiae as in the preceding cases. These patients do not con- valesce as rapidly as do those without tonsillar symptoms, and there is often a strong suspicion of an underlying grave infection. Cases with exactly parallel early histories have been found to develop endocarditis and in rare cases the petechiae have proved to be due to malignant endo- carditis. The majority of these cases, however, are benign and recover without permanent damage. 3rd: There is a variety of purpura rheumatica which so closely resem- bles erythema nodosum as to lead us to the conclusion that the latter con- dition is but another form of purpura, dependent upon some unknown in- fection. In these cases the nodes—tender and erythematous—with in some, limited evidences of petechiae follow. A few days of tender or stiff joints, or without joint symptoms; only the pains due to the presence of the nodes and “stiff legs” follow. The ecchymosis persists several weeks, the nodes gradually disappear with full return to health. In children PURPURA 545 (2 to 8 years or older) the course is shorter than in the adult. There is a tendency to recurrence or a subacute course in some of the adult cases. Life is never threatened and full recovery may be expected. Recurrence is more likely with all forms of “rheumatic” than with the simple purpura. (c) Purpura hemorrhagica (Morbus maculosus Werlhofi) Werlhofs Disease is associated with hemorrhages from one or more mucous membranes with the usual dermal bleeding of purpura simplex in most cases. This is the gravest form of purpura, for in individual cases bleeding from many surfaces or into vital organs (brain) may threaten life. Hemorrhages from the nose, kidney, intestine, bladder, or bronchial mucosa may promptly deplete the weak subjects who are most predisposed to the disease. It occasionally happens that hemorrhage into the brain substance causes hemiplegia; into the brain membranes hemorrhagic men- ingitis. The purpura fulminans of the adult is an example of this form of so-called primary purpura. In such cases previously healthy subjects are suddenly seized, hemorrhages from several mucous membranes are coin- cident, septic symptoms promptly develop and death may follow within the first or second week. I have elsewhere in this chapter mentioned the purpura fulminans of early life, in which the symptoms as a rule, do not include bleeding from the mucous surfaces and justify its classification as a malignant type of purpura simplex of early life. The blood picture of Werlhof’s disease is that of secondary anemia. In the graver cases the blood clot does not contract, if it does, the coagu- lation is slow, and the blood platelets are markedly diminished (normal 250,000 to 400,000 per c. mm.). The lower the red count and color index the longer the convalescence and the graver the prognosis. The prognosis of Werlhof’s disease is now materially and favorably influenced by the prompt use of the animal serum after the method which prevents anaphylaxis and which we have recommended (Eisner and Header) for the treatment of the chronic forms of' the disease. In the adult fulminat- ing purpura, the prognosis has been materially improved by the intro- duction of animal serum (preferably rabbit serum). Morbus Werlhofi may, because of hemorrhage into the appendix cause symptoms of appen- dicitis. One such case I had in my practice where the appendicular symptoms were the first and simulated appendicitis; the appendix was removed, was hemorrhagic, in two days other hemorrhages followed from mucous surfaces, and the significance of the hemorrhagic appendix was cleared. The patient made a perfect recovery without recurrence of symptoms. Uncomplicated Werlhof’s disease which is not of the ful- minating type usually leads, after slow convalescence to permanent re< 546 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS covery. Our experiences with the graver types of the disease with mod- ern treatment have been exceedingly encouraging. In offering the forecast in any case of threatening purpura it is safe to conclude that the changes from hemorrhage, barring cerebral apoplexy, are insignificant compared with those of complicating nephritis. (d) Chronic Purpura Chronic purpura has received but scant attention from writers on internal medicine, yet it is a complex which is not infrequent. The clin- ical picture is kaleidoscopic and the cycles of the disease include repeated recurrences of all classified types of the disease in the individual case. In the chronic cases, with a simple purpura, there may be a prompt addition of the rheumatic form, and while this seems in the ascendency, the hemorrhagic nature of the disease may be emphasized by drains from one or more mucous surfaces, occasionally hemorrhage into the brain or into hollow or solid viscera. Besides this, chronic purpura may alternate with erythema multiforme as we found in one of our cases (Eisner and Meader). Two or more forms of purpura may be present and persist with varying intensity during limited periods at the same time. In rare cases (one of which we have reported) whether because of embolic infarct, thrombosis or necrobiosis, due to some other unknown pathologic cause, death of the hemorrhagic skin results. Chronic purpura is exceedingly rebellious to ordinary treatment— repeated relapse is the fate of almost all. Two of our cases cover a period of twelve and fourteen years respectively. Osier mentions a case which was purpuric 36 years and Ilalsted operated on a case of cancer in which the patient had been purpuric since childhood. Bensaud and Rivet give the most complete resume of this subject. They report cases “with periods of quiescence, during which the return to apparent health seemed complete, but the phenomena recurred on extreme fatigue.” There are two forms: (1) the continuous and (2) the intermittent. 1. The continuous form is associated with general debility, rheuma- tism and gastro-intestinal symptoms. Ecchymoses come and go during many years; the individual petechial spot disappears promptly. Epistaxis and gingival hemorrhages are frequent. There are always some evidences of purpura present but without the greater accidents which characterize the free crises of other forms of purpura hemorrhagica. 2. The intermittent form of chronic purpura is more frequent than the continuous. In the crises there are “abortive and anomalous phenom- ena.” Crises may be preceded for months or years by frequent isolated PUKPURA 547 hemorrhages, nasal and gastric. The exacerbations are in no way distin- guishable from Werlhof’s disease. Slight fever may be present. Be- tween attacks the patient usually appears absolutely normal. Slight cause produces prodromal symptoms which are promptly followed by hemor- rhages. Recurrences have been observed covering periods of over 20 years. Intermediary periods may be long—seven—eight and in one case seventeen years. The mode of termination is variable. Long latent periods do not jus- tify the conclusion that the patient is cured. Patients may die during a crisis. The disease cannot be considered benign. Hemorrhage is the cardinal symptom of all types of chronic purpura. The blood picture shows secondary anemia while the blood clot does not contract, the coagulation time is normal and the blood platelets are diminished. The increase of blood platelets is favorable. The results of treatment with rabbit serum (pi'eventing anaphylaxis) is encourag- ing, and while not all are permanently cured, symptoms are promptly con- trolled and long periods of latency may be expected to follow. The im- provement is often surprisingly prompt. In the chronic cases the animal serum is a life saving remedy. (Eisner & Meader.) In all grave pur- puras the absence of regenerative forms (nucleated red corpuscles) nrgues against a favorable prognosis. Thayer holds that hypoleukocytosis in the acute anemia is unfavorable as is also “the greatly increased per- centage of small mononuclear elements.” (e) Henoch*s Purpura (1874) Henoch’s purpura is a variety which may he associated with urticaria or erythema, with symptoms referable to the gastro-intestinal tract more or less toxemia and albuminuria very often. This variety was originally described by Henoch and considered clinically by Osier. The visceral symptoms include gastric, splenic and nephritic disturbance. The gas- tric and intestinal symptoms often arise suddenly, are suggestive of appen- dicitis, intestinal hemorrhage may be present and due to intussusception, vomiting and colic are frequent. My most serious cases have shown posi- tive evidences in the urine of nephritis. The spleen is enlarged and edema is not unusual. It is a doubtful question whether Henoch’s purpura is a primary disease, whether it is not due to intestinal infection or whether uremia is not responsible at times. When the complex is associated with chronic nephritis it usually leads to death. Henoch’s purpura is in reality erythematous although with increas- ing intestinal and visceral symptoms there may be petechiae. The com- plex is liable to recur and is usually found in children. The prognosis is good in almost all cases which are not burdened by serious complications (nephritis, etc.). 548 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS (f) Hemophilia Hemophilia is an expression of the hemorrhagic diathesis which is congenital, hereditary and permanent. It attacks the male members of families of “bleeders” and is transmitted by the female offspring of these to following generations. Females remain unaffected. They do not bleed, though their male offspring shows the classic features of the dis- ease early in life. These “bleeders” continue to bleed during abnormally long periods when they prick or cut themselves or after any mechan- ical insult. The cutting of the umbilical cord, circumcision, the eruption of a tooth or extraction may prove the hemorrhagic diathesis. In some, the bleeding may not occur until varying periods following birth. There are enormous variations in the symptomatology of hemophilia. Some “bleeders” may never bleed hut once, others bleed on slight cause, learn their tendency and with caution live to ripe old age. If the hemophilic lives beyond puberty the chances are that his life will not be shortened. With increasing years the chances of bleeding are reduced. The serious cases are likely to die during early childhood. There are no clinical anomalies which are characteristic of hemophilics. Those whom we have seen, who continued to bleed during adult life were anemic (chloranemia). The blood picture offers nothing characteristic. The coagulation time is reduced in hemophylics and is deficient. There is no organ which may not bleed; bleeding from mucous membranes is the most frequent cause of depletion. These include epistaxis, hematemesis, hemoptysis, intesti- nal hemorrhage, renal, vesical, and bleeding from ulcerated gums (ulcer- ative stomatitis and gingivitis). Pyorrhea alveolaris frequently retards the progress of hemophilics. Petecliiae or large surface hemorrhages may arise suddenly hut are more limited usually than with other forms of purpura. Joint hemorrhages are usually absorbed, permanent damage may occasionally follow (Ero- sion, anchylosis and contracture) usually there are no permanent lesions. The knee is the most frequent seat of hemorrhage. In individual cases the bleeding may continue during exacerbations from only one organ, as the kidney or bladder, nose, stomach or intes- tines. Senator’s case has become famous in which a bleeding kidney re- moved from a hemophilic, girl, aged 19 years, was found normal, but she never had recurrence of hemorrhage. Hemophilia is not limited to any one portion of the world, it is rare hut is universally distributed. Grandidier gathered the records of 93 hemophilic families in Germany with 258 bleeders of which 22 were women. Bullock and Fildes in their report give a full bibliography of the subject. Morawitz reports the family Mampel which has been ob- served at Kirchheim near Heidelberg since 1827 and since that time has never been free from bleeders. ERYTHREMIA 549 References Bensaud & Rivet.

Primary Erythremia (Osier’s Disease, Vaquez Disease, Polycythemia vera, Plethora vera) Osier’s Disease is characterized by an excess of red blood corpuscles, an increase in the volume of the blood, the subjective appearances of ple- thora, with enlargement of the spleen and in all likelihood a lesion of the bone marrow in which the erythroblastic elements are primarily involved. With primary polycythemia there may or may not be cyanosis. True erythremia exists without known cause. It is a disease of adult life (SO- SO years). The prominent and cardinal symptoms of plethora vera, as the disease is sometimes named, are the increased number of red blood cor- puscles, increased volume of the blood, increased viscosity, the plethoric appearance of the patient and the enlargement of the spleen. Barring the enlargement of the spleen, the blood features of primary and secondary erythremia are practically identical. The striking appearance of the patient at once creates the suspicion of the disease; the blood count is confirmatory, the cautious physical examination must decide whether the condition is primary or secondary. In my last case I never found the red count below 8,000,000 per c. mm. Much higher counts are recorded. The characteristic color of the face is not materially changed in these subjects by any known treatment. 550 DISEASES OF BLOOD A1ND HEMOPOIETIC ORGANS After venesection there may be less plethora but soon the regenerative process is stimulated and the features of the disease return. The enlargement of the spleen is never so great as in leukocytic leu- kemia. When the spleen is enormously enlarged it may he positively con- cluded that there is some complication. In a few authentic cases the liver has been found slightly enlarged. Destruction of large numbers of red blood corpuscles may lead to hemo- globinuria—a dark urine with urobilin. The disease is progressive, there is marked tendency to arterial degeneration (arteriosclerosis) and in some cases hypertension is prominent. Polycythemia as it advances may finally lead to dilatation of the heart and degenerative changes of the myo- cardium. These conditions with dropsies (edema, ascites, hydrothorax) are associated with albuminuria and are evidences of the terminal stage of the disease. UhthofF has reported purpuric symptoms in some of his cases. He found bleeding from the gums, stomach and intestines after which his patients were materially relieved. Erythromelalgia has been noted by several continental observers (Turk, Weintraud and others). When subjective symptoms are in the ascendency and persist, it may be assumed that the disease is progressing. The most unfavorable subjective symptoms are extreme fatigue, vertigo of the Meniere type (Naegeli), vomiting, somnolence and dyspnea on slight exertion. Albuminuria per se, without positive evidences of nephri- tis is usual and without decided prognostic significance. Persistent abdominal pain is an early symptom, usually recurrent and not of importance. These patients are usually obstinately constipated. There are atypical cases, in all of which, however, there is erythrocytosis. Geisbock’s polycythemia hypertonica is without perceptible enlargement of the spleen but with abnormally high systolic blood pressure. Morris has reported cases in which there was slight enlargement of the spleen but no polycythemia. Naegeli does not accept these as true erythremia. Blood Picture.—Erythrocytes.—The average count in plethora vera ought not to be below 7,000,000 per c. mm. and may reach to 10 millions or higher. Osier reports 11,600,000, Stern 13,800,000 per c. mm. Hemoglobin averages between 100-140. Rosengart reports 190-200. Color index is surprising low. The individual cells are pale. The rela- tive leukocytic count is not materially disturbed. There is usually a slight leukocytosis. In severe cases the leukocytes may suddenly or grad- ually increasec Osier reports one case in which there were 91,000 with 93.2 per cent of neutrophilic leukocytes. Eosinophilia is present in most cases, while mast cells are according to most observers constantly present and strikingly increased (Morris, Muller). The entire quantity of circulating blood is increased as is its viscosity and specific gravity. The disease is insidious in its onset, is ERYTHREMIA 551 progressive, exceedingly chronic, the patient living many years in fair health. It is practically uninfluenced by medicines, save free catharsis. Diet has a Avholesome effect in relieving some temporarily Avliile repeated venesection often relieves subjective symptoms. Osier’s disease is incur- able, death may result from secondary complications, usually from dilated and insufficient heart Avith general dropsy including ascites. Hemorrhage into the brain or its membranes; thrombosis and infarct, invading the spleen are causes of death. Polycythemic patients Avhen they contract in- fection or are subjected to extra strain are found below par and without the resistance to withstand serious disease. Convalescence from insignifi- cant complications is abnormally slow.* 2. Secondary Erythremia {Symptomatic Polycythemia) Secondary polycythemia may be symptomatic of any disease in which the blood is concentrated, in which there may be stasis due to circulatory obstruction or in which the lungs have not accommodated themselves to changed altitude or in which, because of poisoning, coal gas or drugs, as potassium chlorate, phosphorus, coal tar products, sulphuretted hydrogen, (methemoglobinemia and sulphemoglobinemia) blood changes follow. The leading primary diseases which lead to symptomatic plethora are chronic heart diseases, congenital heart defects, emphysema with right heart involvement, obstructive lung, laryngeal and bronchial disease, any disease causing chronic dyspnea, diabetes mellitus and insipidus, Asiatic cholera, depleting diarrhea and high altitude, besides the poisons men- tioned in the preceding paragraph. The prognosis of all of these conditions must be separately considered; polycythemia—the symptom—is an expression of added gravity in most chronic heart diseases and congenital defects and influences prognosis as such. It is surprising on the other hand to find with congenital heart lesions and many chronic diseases how comfortable the cyanosed and poly- cythemic subject remains during years, but how ready he is to yield to slight cause. In such cases the primary lesion is the cause of death, the erythremia is a condition which can never be credited with paramount significance. Parkes Weber in an interesting article on the Prognostic Significance of Secondary Polycythemia in Cardiopulmonary Cases makes the follow- ing statement: “Just as hypertrophy of the Avails of the heart is useful in so far as it * (Besides Osier’s classic article which placed the disease upon a scientific basis and gave it the name it now bears, Senator’s monograph is most instructive.) (See References.) 552 DISEASES OF BLOOD AND HEMOPOIETIC ORGANS compensates for mechanical defects in the valvular apparatus, so also is polycythemia useful in so far as it compensates for difficulties in the proper oxygenation of the blood and tissues of the body; but just as in cardiac valvular disease great hypertrophy of the heart indicates some grave defect in the valvular mechanism, so also an extreme increase in the number of erythrocytes in the blood points to there being great im- pairment of the normal process of oxygenation of the body.” With the “cardiopulmonary cases,” however, with which I am chiefly concerned in the present paper, the prognostic significance of the polycythemia is, I believe, somewhat different, or rather, as I would prefer to put it, the outlook is exceedingly grave at the stage of the disease when cyanosis and a great degree of polycythemia become striking clinical features. With diabetes we have noted the secondary polycythemia in the more serious forms of the disease, usually most marked in advanced cases (See Diabetes Mellitus). The 'polycythemia following change to a high altitude is transitory in normal subjects and usually yields without permanent damage. Poly- cythemia due to chronic poisoning yields in most cases to discontinuance, though with acute poisoning it is always an expression of the gravity of its cause. The blood picture of secondary polycythemia is much like that of Osier’s disease, unless as sometimes happens the primary lesions may produce changes. Thus with pneumonia or acute infections, with Asiatic cholera, the leukocytic count will he markedly influenced. The poly- cythemia neonatorum is physiologic and transitory. References Cautley.

Section V Diseases of the Digestive Apparatus A. Diseases of the Mouth Stomatitis * (a) Simple Catarrhal or Erythematous Stomatitis Stomatitis or acute inflammation of the mouth may be due to: 1. “Chemical or mechanical irritation including acids, alkalis, tobacco and highly seasoned food.” 2. “Chronic poisoning by mercury, arsenic or lead.” 3. “Extension of inflammation from the neighboring parts, e. g., teeth, nose, nasopharynx.” 4. “Gastro-intestinal disturbances.” 5. “Constitutional disturbances, e. g., measles, variola, scurvy.” (Woodwark.) In mild cases the affection is limited to the gums; in the more severe to the buccal mucosa, the tongue and the lips. There are no marked general disturbances though children and susceptible adults have slight elevation of temperature. The sublingual and submaxillary glands are often swollen. The course of the disease is short, cure follows in the average uncomplicated case soon after the removal of the cause. With the infections the dryness of the mouth and salivation with local swelling of the mucosa and glands promptly disappear with recovery. (6) Aphthous Stomatitis Aphthous stomatitis is more severe than the simple, there is a patchy (gray) deposit on the lips, gums and tongue, with considerable glandular swelling and with the disappearance of the grayish, fibrinous deposit, * The surgical conditions are not treated in this work, neither are the surgical diseases of the nares, postnasal space or tongue. 553 554 DISEASES OF THE DIGESTIVE APPARATUS superficial but painful ulcers remain, which with cautious cleanliness heal in the course of four to seven or ten days. The aphthous deposit may cause multiple ulcerations of the buccal mucosa, the tongue, lips, and gums; the glands may be tender, suppuration is exceedingly rare. With added gingivitis, the teeth are at times loosened but are not lost. The inability to take food, particularly in young children, who are oftenest afflicted, may lead to weakness but to nothing more serious. We have seen children and adults in whom the disease has extended to the pharynx, the tonsils and tonsillar pillars who have finally shown few superficial deposits and ulcerations, which have promptly healed, though progress has been retarded by the extension. The epidemic form of aphthous stomatitis is separately considered (See Toot and Mouth Disease). (c) Ulcerative Stomatitis Ulcerative stomatitis may be either primary or secondary. The sec- ondary forms are associated with the diseases of childhood, including scarlet fever and other infections elsewhere considered. The prognosis depends on the virulence of the primary infection. Primary ulcerative stomatitis is unquestionably of infectious char- acter. In the severe forms fever and rapid, at times erratic, pulse (arhythmia) may accompany ulcerations of the buccal mucosa, the gums, lips and tongue. There is a characteristic odor, glandular enlargement. In children and adults many may contract the disease from the same drinking cup. In adults there is always a justified suspicion of mercury as the cause which demands investigation. The month may infect itself from the neglect of the teeth. In rare eases, the infection causes an erythematous eruption which creates the suspicion of scarlatina. The ulceration and swelling with foul breath not only rob the patient of appetite but make swallowing and mastication exceedingly painful. We have never known of a death in our experience, though young and feeble children (infants) are reported to have died of the disease. The duration averages two weeks. Hon-inf ectious (?) and limited ulcerations of the mouth in both children and adults heal readily. In some there is a strong tendency to recurrence. Cankers of the mouth may often prove exceedingly painful and their recurrence at short periods or the constant presence of one or more may make the patient wretched. Such cases are dependent upon an underlying cause which demands close investigation. When discovered (often difficult) recovery follows. Jacobi described an herpetiform stomatitis which he has found in neu- rotic individuals and characterized it stomatitis neurotica chronica. It is DISEASES OF THE MOUTH 555 exceedingly rebellious to treatment. Osier says “it may precede or accom- pany the fatal forms of pemphigus vegetans ” The Plaut-Yincent angina, infection from the fusiform bacillus, may limit its ravages to the gums. It is not without danger when wide- spread. (See Vincent’s Angina.) Leukoplakia Buccalis, buccal psoriasis—leukokeratosis mucosae oris is a condition of “patchy tongue”—the roof of the mouth, gums, lips and cheeks may be spotted, with whitish, grayish thickenings in patches, the tongue may be uneven or “wrinkled”; the tissue involved may become fissured. Epithelioma may develop after long periods of chronicity. The condition is always secondary, found in smokers usually; it is of syphilitic origin with but few exceptions. We have never seen a case in adult life which could not be traced to syphilis. Cure of the local lesion is the exception. It does not interfere with life save as cancer develops. Oral Sepsis (Hunter).—See Pernicious Anemia. Foul or fetid breath is always secondary, due either to disease of the teeth, pyorrhea alveolaris, tonsillar deposits, usually millet-seed sized, in the crypts of the tonsils, diseases of the stomach, sudden inhibition of digestion after emotion or shock or nasal disease. Foul breath is often rebellious to treatment but persistence after the recognition of the cause leads to cure. The causative relations of stomatitis—gingivitis—and pyorrhea alve- olaris to the arthritides and other infections are separately considered (See Rheumatoid Arthritis—Chronic Rheumatism, etc.). (d) Noma—Cancrum oris—Gangrenous Stomatitis, Wasserkrebs (German) IsToma was described by tbe older writers on medicine as afflicting many and after rapid progress with gangrenous destruction of the cheek (one or both) with all of the features of overpowering sepsis, these unfor- tunates usually died. At present we rarely see characteristic noma or cancrum oris. Our entire experience is limited to two cases. One of a young lady aged about 28 years who developed the disease after biting her cheek, the constitutional evidences of sepsis were present early, the gangrenous destruction was prompt and death followed in ten days in coma with albuminuria and casts. The odor was characteristic of gan- grene and the suffering intense until she became unconscious. As a rule there is little pain. Our second case was in a child in whom the process was rapid with deep sloughing of one cheek within three days and death with all of the earmarks of general sepsis about the sixth day. Kindborg reports aspiration pneumonia as a cause of death and he be- lieves that noma never develops in a normal mucosa. 556 DISEASES OF THE DIGESTIVE APPARATUS The milder cases recover; those with deep sepsis, far-reaching gam grene without resistance and of tender age die. Adults may develop the more malignant type and die before the end of the tenth day. High temperature, rapid erratic and small pulse with evidences of toxic nephritis are all unfavorable, when together recovery is not to be expected. (e) Stomatitis Parasitica—Thrush-Soor—Muguet Thrush in healthy children and adults is an insignificant infection, dependent upon the oidium albicans. Its favorite seat is in the changed or diseased mucosa. Most cases may be traced to carelessness, uncleanli- ness of bottles, nipples or utensils. The disease is preventable. In chil- dren and healthy adults recovery is prompt. There are cases of tuber- culosis, carcinoma of the stomach, pernicious anemia and diabetes (the latter very often in the terminal stage) which are unfavorably influenced by the development of this form of stomatitis. There is always in neg- lected or cachectic cases danger of spread to the esophagus, stomach and intestines. When there is extension to the intestines obstinate diarrhea is often depleting. (0 Mercurial Stomatitis—Ptyalism Stomatitis with salivation following the administration of mercury or the use of mercury in the various occupations offers a favorable prog- nosis, though it often resists treatment during many weeks and may cause ulcerative changes from which recovery is also slow. Even small doses of mercury in some in whom the usual cautions have been neglected may lead to ptyalism. We have seen patients much reduced "by uncon- trollable salivation and extreme weakness has followed in some cases, but recovery in the average case is the rule in from two to three weeks. Marked anemia and slight albuminuria disappear with the relief of local symptoms and convalescence is rapid. In children the development of the teeth or the decay of those already erupted is not unusual. References Hunter (Wm.). The severest anemias. London, 1909. Jacobi (A.)- Tr. Ass. Am. Phys., 1894, ix.

DISEASES OF THE SALIVARY GLANDS 557 B. Diseases of the Salivary Glands 1. Mumps Epidemic Parotitis (See Section I, The Infectious Diseases.) 2. Parotitis The symptomatic parotitides are considered with the primary diseases which they complicate. (See Typhoid, Pyemia and other Infections.) Chronic parotitis is almost always a secondary disease associated with nephritis, syphilis or it is due to chronic poisoning, lead, mercury or iodin. 3. Mikulicz’s Disease (.Bilateral Salivary Swellings) Mikulicz’s Disease (1888 and 1892) is a coincident enlargement of the parotid, lacrimal and buccal glands which is chronic, continuing many years and is of uncertain origin. In America the disease is rare, though several cases have been reported. The organic changes in the glands usually persist in spite of treatment. Osier reports the case of a girl of eleven, with enlarged spleen, death resulted from chronic tuber- culosis and “before death the enlargement of the salivary glands had disappeared—the lacrimal glands were completely sclerotic.” A recent article by Thursfield calls attention to the cases “which illustrate all stages of gradation between the strict type (cases with in- volvement of the lacrimal and salivary glands without changes in the lymphatic glands and in the blood) and those in which there is a positive picture of leukemia or lymphosarcoma. It is possible for cases which originally show the characteristic coin- cident enlargement of the parotid, lacrimal and buccal glands, to develop grave blood changes and present in the terminal stages, with grave anemias, more particularly leukemia. In these cases many lymph nodes are enlarged throughout the body and there are organic changes in the spleen. Most of these cases retain the bilateral swelling of the salivary glands. Brunn’s classification, in which the “Mikulicz symptom complex” was the leading feature and which must serve to prove the association of grave blood changes in a number of cases also corroborate the con- clusions of Senator, Stock, Dunn and Thursfield, that the complex may be a phenomenon of leukemia. 558 DISEASES OF THE DIGESTIVE APPAKATUS Brun’s classification follows: “I. Cases without alterations in the blood. A. Without swelling of the spleen or lymphatic glands. (a) Symmetrical swelling of the lacrimal and salivary glands. (b) Symmetrical swelling of the lacrimal glands alone. (c) Symmetrical swelling of the salivary glands alone. B. With swelling of the spleen or lymphatic glands. (a) Symmetrical swelling of the lacrimal and salivary glands. (b) The same with infiltrations of the skin. II. Cases with alterations in the blood. A. Severe anemia with lymphatic pseudoleukemia and aplasia of the bone marrow. B. Leukemia.” Occasional cases of the complex show a marked hereditary influence. Quincke reports the case of a man, aet. 45, with congenital enlargement of both parotids whose father, two uncles, five brothers and two sisters showed the same anomaly. Tuberculosis, gout and syphilis may he coincident with the complex and influence prognosis materially. Thursfield, whose observations are exceedingly valuable, makes the following statement: “When there is no involvement of the lymphatic glands or spleen and no alteration in the blood, the disabilities of the affection seem to be confined to the disfigurement, and to a certain degree of discomfort from both of which the lapse of time, one to five years as a rule, releases the patient. When the lymphatic glands or the spleen are enlarged the outlook is more uncertain; of Howard’s twenty “pseudoleukemic” cases, six died; and of the definite leukemic cases, Stock’s patient alone sur- vived more than six months.” The removal of the enlarged lacrimal glands (Elliott) influenced the salivary enlargements in one case.

Diseases of the Pharynx (The infectious diseases of the pharynx, including the tonsils, are considered in Section I, Infectious Diseases.) 1. Circulatory Anomalies (a) Hyperemia of the Pharynx.—Congestion of the pharynx may depend upon primary disease, results from local irritation or it may he secondary; it may be either acute or chronic. Acute hyperemia accom- panies the eruptive diseases of childhood, hence its sudden appearance suggests vigilance and search for infection. In the adult irritating chemicals, highly seasoned or abnormally hot foods, colds, nasal irrita- tion, prolonged or abnormal use of the voice may cause transitory hyperemia. Chronic hyperemia is due to circulatory, obstructive, chronic local disease or other factors which continually act as irritants. The circu- latory disturbances which are paramount are chronic heart lesions, aneu- rismal pressure, emphysema with heart changes and bronchitis, tumors of the neck or mediastinum. Chronic pharyngitis and nasal diseases cause continuous hyperemia. Tobacco and alcohol are the most frequent fac- tors in causing chronic pharyngeal hyperemia. (b) Hemorrhagic symptoms may be due to the hemorrhagic diathesis, purpura, local disease, traumatism and occasionally to vicarious men- struation. (c) Edema of the pharynx (uvula and soft palate, peritonsillar tissue) is usually of inflammatory origin with tonsillitis or peritonsillitis, when the prognosis is good. It may be an evidence of stasis (circulatory), pressure, or with nephritis and general edema it may prove threatening. 2. Pharyngitis (a) Acute Pharyngitis. Acute catarrhal pharyngitis is a common disease, which almost always gets well within a few days. It is an accompaniment of many infections which latter, when it remains limited, are not affected by it. With rhinitis and tonsillitis it is rarely absent. It is often the earliest symp- 560 DISEASES OF THE DIGESTIVE APPARATUS tom of the infectious diseases of early life (exanthemata) though it may be primary and due to any of the causes mentioned in connection with acute hyperemia. The inhalation of all kinds of dust frequently pro- vokes it. (6) Chronic Pharyngitis Preceding acute neglected pharyngitis, tobacco and alcohol, nasal and postnasal diseases, the prolonged use of the voice (clergymen, lecturers, etc.) are the leading causes of chronic pharyngitis. The prognosis is favorable before the changes in the mucosa are not too far advanced for relief of symptoms. Pharyngitis sicca is never cured until its cause, usually in the nose or postnasal space, has been removed. (c) Ulcerative Pharyngitis (See Syphilis, Tuberculosis, Foot and Mouth Disease and the various infections which it complicates.) The prognosis depends upon the ability to remove its cause. (d) Phlegmonous Pharyngitis and Retropharyngeal Abscess Phlegmonous pharyngitis and retropharyngeal abscess are always secondary, often threaten life by local swelling—edema and associated involvement of the larynx (edema of the glottis). Phlegmonous tonsil- litis and peritonsillitis involve the pharynx and postnasal space. Sepsis, meningitis, otitis media and mastoiditis are among the dangerous sequelae, also toxic nephritis. In rare cases mediastinitis and pneumonia have ended life. Phlegmonous pharyngitis with erysipelas or any other infection is never to be lightly regarded. Retropharyngeal abscess may follow injury of the mucosa from foreign bodies; its greatest dangers are descending extension, associated compression, edema and pneumonia. It is always a surgical affection, the favorable outcome depends on the nature of its cause, early recognition and radical treatment. Disease of the cervical vertrebrae, usually tuberculosis, fracture or other bone changes, when associated with retropharyngeal abscess, make the outlook bad. (e) Ludwig’s Angina (Angina Ludovici) Ludwig’s Angina (first described by Ludwig in 1836) is a phleg- monous inflammation of the connective tissue of the neck, involving, as a rule, the deep and superficial tissue on one side in the submaxillary DISEASES OF THE PHARYNX 561 region, though in severe cases it may extend downward and to the oppo- site side. It is always of infectious origin, is a sequel of streptococcus infection, scarlet fever, infection from contaminated milk (epidemic streptococcus), typhoid and diphtheria. There are cases which are with- out known primary cause, others which follow injury and infection. The history of these cases prove that with deep constitutional infection, wast- ing disease and lowered vitality, there may he and often is a prompt sepsis, phlegmonous and gangrenous breakdown of tissue and deep in- volvement of the sensorium, rapid and feeble pulse, with albuminuria. In such cases the prognosis is grave and life may be in danger for several days. The phlegmonous periparotitis and involvement of the deep fascia of the neck with septic scarlet fever prolongs convalescence and with feeble pulse, nephritis and uremia present a serious complex. Edema of the fauces or glottis or both is always alarming. Idiopathic cases if treated radically early, as a rule, recover slowly after varying periods of sloughing and repair. Ludwig’s angina shows marked tendency to gangrene within the phlegmonous area. Sepsis and nephritis cause the death of a large proportion of such cases. The mortality of the disease is high—the danger period follows several days of slight febrile move- ment without cerebral symptoms. In unfavorable cases there is a sudden exacerbation of symptoms, collapse, dyspnea, 'cyanosis, pharyngeal and laryngeal edema, unconsciousness and cardiac insufficiency. Ludwig reported such cases which died before there was time to offer assistance. Dyspnea (asphyxia) is the prominent and threatening symptom. Unless these cases can be reached by surgical means they promptly die. A rally should not deceive the clinician, for relapse and sudden death may fol- low it. Aspiration bronchopneumonia, pleurisy, edema of the larynx, sepsis, and cardiac toxemia are the leading causes of death. In pure Ludwig’s angina the mouth is always infiltrated and Thomas bases his differential diagnosis on this fact. This is not the case with other forms of cellulitis (scarlet fever) which are considered by many (Osier, etc.) as Ludwig’s angina. Broad of Syracuse has partially reviewed the history and literature of this subject in a paper not yet published and has fully reported a case which terminated favorably. We have taken the following data from Broad’s paper: Davis reported 10 cases with a mortality of 40 per cent. Sharkey’s mortality w7as per cent. Thomas reported 106 cases with 43 deaths—40 per cent mortality. Naturally the percentage of recoveries varies materially if we include the neck infections which are phlegmonous following scarlet fever and other infections, many of which recover. These are not included in the above figures. 562 DISEASES OF THE DIGESTIVE APPARATUS References Broad (G. B .). Not yet 'published. Davis. Am. J. Med. Sci., Feb., 1904. Annals of Surgery, 1906.

Diseases of the Esophagus 1. Acute Esophagitis Inflammatory or ulcerative changes of the esophagus are: (a) Catarrhal (i. Acute or ii. Chronic). (b) Pustular. (c) Phlegmonous. (d) Croupous. (e) Diphtheritic. (f) Ulcerative. (g) Corrosive. (h) Varices. The majority of inflammatory or ulcerative changes in the esophageal mucosa are due to thermic insults, chemical irritants, foreign bodies or inflammatory conditions accompanying other diseases. (a) Catarrhal Esophagitis i. Acute.—The acute catarrhal inflammation of the esophagus is usu- ally so mild as to give rise to no symptoms. When extensive and deep, as DISEASES OF THE ESOPHAGUS 563 it is at times with catarrhal bronchitis, tracheitis, pharyngitis, and acute nasopharyngeal infections and tonsillitis, the membrane is congested, there is epithelial desquamation and some dysphagia. The pathologic process follows the stages of acute catarrhal inflammation and unless there is some serious underlying disturbance it runs its course in a few days and leaves the tube intact. ii. Chronic Esophagitis.—Chronic esophagitis (catarrhal) leads to thickening of the mucosa and submucous tissue with hypertrophy of the muscularis. With alcoholic gastritis it may prove an annoying compli- cation, particularly if limited to the cardiac end when with productive change, stricture may develop. In rare cases polypi form. After acute esophagitis due to corrosive poisons, carbolic and mineral acids, caustic potash, arsenic and other destructive lesions, chronic esophagitis may develop with final narrowing of the tube. The evidences (subjective) may be long postponed in such cases. The obstructive symp- toms and physical signs (obstruction to the passing of the sound into the stomach) are often in evidence when the patient presents. Only surgical interference helps these cases. Many are not threatening and live with moderate narrowing of the tube many years. In some cases after caustic poisons have been swallowed, esophageal and aural lesions develop late and are persistent. One of our cases is living over 30 years after swal- lowing ammonia with deafness and chronic esophagitis. (6) Pustular Esophagitis Pustular esophagitis is secondary to grave infection, as a rule, and is often part of serious constitutional disturbance. Smallpox with which pustules form in the esophagus is usually of the malignant type, though not always, and the complication is by no means always fatal. Pustular esophagitis may develop with other infections. The prognosis is not materially influenced by the complication in the majority of cases. It is the primary process upon which the forecast rests. In smallpox the eruption may be present in the mouth, fauces and esophagus at the same time. In most of these ulceration and cure follow. (c) Phlegmonous Esophagitis This may follow from descending extension of phlegmon of the pharynx; it may be associated with poisoning or infection which disrupts the esophagus—usually septic processes. Sepsis and pyemia often cause infiltration, change in the superficial and deep structures of the esoph- agus. Phlegmonous disease associated with any constitutional infection is always grave, at the same time exceedingly painful. 564 DISEASES OF THE DIGESTIVE APPARATUS (d) Croupous Esophagitis Croupous disease of the esophagus may be associated with croupous inflammation in other organs, as croupous pneumonia, croupous laryn- gitis and rarely there are membranous deposits which are primary— independent entirely so far as we are able to conclude of deposit elsewhere. Croupous esophagitis is usually of streptococcus origin and may be sec- ondary to streptococcus tonsillitis. With most of these conditions the prognosis is good, though as in other forms, most depends upon the nature of the primary infection. (e) Diphtheritic Esophagitis This form of esophagitis is less frequent since the introduction of the antitoxin for diphtheria, though occasionally in neglected or malignant cases, we find the membranous deposit in the esophagus. The prognosis depends on the nature and extent of the infection as well as on its virulence and the patient’s resistance (See Diphtheria, Section I, Infectious Diseases). (f) Ulcerative Esophagitis Ulcerative esophagitis may be cancerous. It may develop in infants while nursing; with long continued disease decubitus ulceration may prove painful and serious. Decubitus ulcers usually form in the depleted who are emaciated from chronic disease (nervous, tuberculous, chronic and subacute infections of all kinds) and are usually located hack of the cricoid cartilage which by pressure against the esophagus causes the “bed sore,” for it is that in reality. Peptic ulcers of the lower end of the esophagus are rare but may form and in the process of healing may cause cicatricial contraction. Perforation is exceedingly rare from ulcer, it is a fatal complication (See Rupture of Esophagus). Esophageal ulcers are often tuberculous or syphilitic (See Tuberculosis and Syphilis). The .prognosis of all ulcerative esophagitis depends on the primary cause—the corrosive ulcer often heals but stricture is to be feared. (g) Corrosive Esophagitis The corrosive may be associated with the phlegmonous form or it may exist alone, it is usually grave. The shock which follows the taking of a corrosive poison is always great. The changes are usually deep and in children and weak adults the prognosis is often bad. Naturally the extent of the corrosion and shock depends upon the kind of poison and dose. In very young children with chronic stricture after swallowing DISEASES OF THE ESOPHAGUS 565 corrosive poison the prognosis is unfavorable. We have seen one life saved by the establishing of a gastric fistula in the case of a girl not older than four years with a closed esophagus following the taking of caustic potash. She has lived, so far as we know, now over 20 years, feeding herself through the fistulous opening. If the stricture is fortunately lo- cated modern surgery offers some hope. (h) Varices .of the Esophagus Varices of the esophagus often form from long continued circulatory obstruction with chronic heart lesions, pressure, Banti’s Disease and with liver cirrhosis. Their presence can only he suspected during life when there is rupture and consecutive hemorrhage or when seen, through the esophagoscope. The dangers are rupture and depleting hemorrhage. I lost one Banti from erosion of a good sized varix. 2. Spasm and Paralysis of the Esophagus (a) Spasm of the Esophagus (Esophagismus) Esophagismus or spasm of the esophagus is of rare occurrence. It is usually of neurotic—hysterical—origin, alarming to the patient hut without danger and, as a rule, of short duration. The patients are usu- ally robust and young. The spasm is sudden in its onset and at once closes the esophagus to solid food, often to liquids as well. In women the associated fear and ungeared nervous condition are, with the spasm, the leading features. Reassurance and suggestion are sufficient in most cases to quiet the patient and overcome the spasm. Any psychic impres- sion in some, as the passing of the stomach tube, particularly in young hysterical subjects, proves sufficient to overcome the symptom. There is, in most cases, recurrence on slight cause and occasionally esophagismus may alternate with spasm of the glottis (laryngismus stridulus), or both may he present together. The element of suggestion proves a powerful factor in the production and the relief of symptoms. Kindborg mentions incipient cancer as a cause of esophageal spasm. We have never met with a like case. Paralysis of the esophagus is likely to he associated with diphtheritic paralysis in children, occasionally in the adult (see Diphtheritic Paral- ysis). Its prognosis when not a part of extensive paralysis of other organs, is not bad. Esophageal paralysis with brain {tumor') and spincu (b) Paralysis of the Esophagus 566 DISEASES OF THE DIGESTIVE APPARATUS lesions, lesions of the spinal bones, remains unchanged, simply one of many symptoms. The same is true of ascending paralysis (Landry’s Dis- ease). 3. Stricture of the Esophagus Stenosis or stricture of the esophagus may be either (a) extra- or (b) intra-esophageal. Extra-esophageal stricture is due to compression from without; tumors of the neck, enlarged glands, cystic growths, aneurismal dilatations, medi- astinal pressure; tumors (malignant or non-malignant) of the lung and pleura, diseases of the spinal vertebrae associated with tumor formation, abscess, caries or malignant disease of the spine itself, diverticulum of the esophagus, peri- and para-esophageal abscesses, malignant masses springing from the sternum or ribs, pericardial and pleural effusion are among the leading causes which by pressure or torsion narrow the lumen of the tube. Only the removal of the cause, which is almost always im- possible, can overcome the stricture. (a) Extra-esophageal Stricture (6) Intra-esophageal Stenosis Over 60 per cent of all strictures of the esophagus are malignant— carcinomatous—and lead to death unless recognized early. Even the early recognition offers practically no hope though surgeons are extend- ing their knowledge and improving their technic and a few are recom- mending radical interference (See Willy Meyer’s Report of Cases, etc.). There are benign growths of the esophagus which cause narrowing of its lumen—these are usually cicatricial following causes which have been mentioned in connection with the various diseases of the esophagus and the productive changes which may follow. Some of these live many years, comparatively comfortable, when constriction is not too great. Most strictures are at or near the cardia, some hack of the cricoid car- tilage. Stricture of the esophagus when it has existed even a limited time, if very narrow, leads to dilatation above the point of constriction. The presence or absence of Meltzer’s 'phenomenon (Schluck and Spritzgerausch) is of no value in prognosis, though of considerable diag- nostic value in individual cases when correctly interpreted. The phe- nomenon is not present in all cases and according to our experience may in the same case be heard at one time and not at another. The greater the dilatation, as shown by the x-ray or by the amount of fluid or food which it holds, the greater is the obstruction and the more difficult will it be to nourish the patient. We rarely find malignant stricture mul- DISEASES OF THE ESOPHAGUS 567 tiple. The dilatation above the stricture is at once associated with nar- rowing below and collapse of the intestines with, in chronic cases, atrophy of the muscular coat of the stomach and intestines also atrophic changes in the glandular structures. The cachexia, and secondary anemia are in direct proportion to the primary and secondary lesions and the consecutive failure to nourish the patient. Symptoms of esophageal stricture after 40, without previous history of esophagitis or ulcer always creates a strong and justified suspicion of cancer. The prognosis of stricture from whatever cause is promptly given, for we have but to consider its pathology. In cases of doubtful origin, non-malignant—the ability to get sufficient food into the stomach either through the esophagus or gastric fistula will soon solve the problem. Progressive malnutrition, heart weakness and exhaustion is the fate of all of these patients in whom the constriction is extreme. Congenital stricture leads to death wdien complete during the early days of life. In other rare strictures though more frequent than the complete occlusion, the lower part of the esophagus opens into the trachea or into a bronchus. We have never met a case in our practice. Thomas (William) has collected 19 cases from medical literature. 4. Cancer of the Esophagus Neoplasms of the esophagus are, as a rule, cancerous—epithelioma. The lower end of the tube is usually invaded and the growth is annular and constricting. At times the esophagus infiltration is limited and the progress is slow and during a considerable period the stricture may be only partial. We have seen cases in which the growth was so exceedingly slow as to make the diagnosis doubtful. If the cancerous mass is large, the wall of the esophagus and the surrounding structures (glands, etc.) are infiltrated. Metastases may or may not be numerous. Pressure symptoms under such conditions are not relieved and may lead to prompt death. In some cases there is sufficient growth to lead to pressure on the left recurrent laryngeal nerve with paralysis which persists until death. Slight improvement in swallowing may at times prove misleading as may also the vagaries of the disease. With extreme constriction the patient may be able to take solid food during limited periods and be almost com- pletely “closed” in the intervals. Ulcerative changes in the growth may make it possible to get more food into the stomach than had previously entered. Alcoholics are subject to cancer of the esophagus; the disease is more frequent in men than women; it is a disease of middle life and is usually primary. Osier reports 38 cases of cancer in the medical wards of the Johns Hopkins Hospital in 23 years. During the past six years we have seen 8 cases of cancer of the esophagus in 6,300 cases of internal disease. 568 DISEASES OF THE DIGESTIVE APPARATUS We refer the reader to our consideration of cancer as a cause of stricture of the esophagus in this section and repeat what we emphasized, that x-ray examination will lead to localization and will reveal the extent of secondary esophageal changes in most cases. The esophagoscope is a valuable adjunct in the hands of the expert. Fibrous thickening of the esophagus is secondary to conditions men- tioned in this section. Lipomata and polypi are rare—with newer methods these are recog- nized. We have never met either in our practice. There can be but one conclusion—the prognosis of esophageal cancer is bad, patients die of starvation usually, though complications, as with cancer elsewhere, may end life. The average duration of life in our cases has been between 12 and 18 months after the beginning of subjective symptoms. Unquestionably most cancers of the esophagus are tolerated during long periods before their presence is suspected or cause symptoms. Metastases may never follow esophageal cancer, on the other hand, a small carcinoma may have multiple metastases—often more than the larger growths. Metastases to the mediastinal glands, also enlargement compressing the thoracic duct (Gerhardt) hasten death. Secondary nod- ules may form in the esophagus itself. Gerhardt also calls attention to the relative frequency of the associa- tion of esophageal cancer and pulmonary tuberculosis. 5. Rupture of the Esophagus Rupture of the esophagus is exceedingly rare. The wall of the esoph- agus may rupture as the result of softening (Zenker). Emphysema promptly follows whenever there is esophageal rupture from whatever cause. Traumatism—gunshot wounds, stab wounds, and the ulcerative and infiltrating conditions associated with esophagitis, ulceration and can- cer mentioned in this section may occasionally lead to rupture. Death follows rupture promptly in almost all cases from collapse with marked dyspnea, and widespread emphysema. Perforation or rupture of the esophagus may cause periesophageal suppuration. Aspiration pneumonia may follow fistulous openings into the trachea or into a bronchus. Per- foration into the pleura or pericardium leads to death from effusion and added pressure. Pneumothorax has complicated perforation. 6. Dilatation—Diverticulum (a) Dilatation In connection with esophageal stricture we called attention to the dilatation of the esophagus above the point of closure. This is the in- DISEASES OF THE ESOPHAGUS 569 variable result in almost all cases which live any length of time. The extent of the dilatation is a safe guide in deciding upon the degree of narrowing. Rontgen pictures and the stomach tube will prove of mate- rial assistance. (b) Diverticula Diverticula of the esophagus may he acquired or congenital. Some forms are multiple, giving rise to small dilatations here and there, causing but few symptoms. Particles of food are likely to fall into the diverticula and cause symptoms. Weakness of the esophageal wall is one cause of dilatation (local) or diverticulum formation. This is the “pressure diver- ticulum” or e The local dilatation increases be- cause of the pressure and retention of food and is most likely to form at the junction of the esophagus and pharynx. Pulsionsdiverticulum may dilate to such an extent as to cause pressure symptoms, indeed constrict the esophagus itself when food is held without entering the stomach. The condition is purely surgical. Food is often regurgitated, emptying the sac with temporary relief. Traction diverticula are not, as a rule, of great clinicial significance. They result either from congenital defects—“embryonal preformed con- nective tissue strands” which form because of incomplete separation of the trachea and esophagus (Ribbert) or they are secondary to inflammatory changes in the lymphatics, which cause adhesions and consecutive con- nective tissue contraction which draw upon the esophageal wall causing the localized dilatation. Their presence may not be suspected until a foreign body is caught, ulcerates, causing perforation with consecutive suppuration, mediastinitis and death. Uncomplicated and limited, the presence of the traction diverticulum may never be suspected and is found post mortem. References Aschoff. Path. Anatomic. Jena, 1913.

Diseases of the Stomach 1. Acute Gastritis Gastritis may be either (1) acute or (2) chronic. There are several forms of acute gastritis, as follows: (a) Acute Catarrh of the Stomach Acute catarrhal inflammation of the stomach is one of the most fre- quent of all internal diseases. It is, when uncomplicated, a benign catar- rhal inflammation which produces symptoms only of acute indigestion (gastricismus) which yield in the course of two to four days without leav- ing a remnant. It follows dietetic errors, the taking of excessively hot or cold foods, may result from exposure, sudden atmospheric changes, is an accompaniment of anemia and debility. The acute alcoholic 'gastritis is toxic and is considered elsewhere. The association of catarrhal gastritis with duodenitis may cause jaundice (See Catarrhal Jaundice) and post- pone recovery. The stomach contents in most cases of catarrhal gastritis offers nothing of value. In aggravated cases the free hydrochloric acid may be reduced, the digestion is tardy; there may be acetic and butyric acid, a few blood corpuscles and increased mucuSi (6) Infectious Gastritis The infectious type of gastritis follows the ingestion of contaminated food or may be due to an endemic in which many are attacked at the same time (probably streptococcus). Catarrhal grip may also be pres- ent at such times. During epidemics of true grip the influenzal type of gastritis or infectious gastritis is frequently met. Such cases include symptoms which make the patient uncomfortable (localized pain, localized tenderness, vomiting, nausea, hypersecretion, “bilious” vomitus, with the usual malaise and weakness of influenza). Infectious catarrhal conditions of the nasal and upper respiratory passages as well as the pneumonias may be associated with gastritis. With all of these conditions the localized stomach infection is not usually of paramount importance but the primary disease and the patient’s resist- ance are most important in offering a forecast. In old people and in the weak the added infection of the stomach may help to undermine resistance but such influence is exceedingly rare as the stomach changes are few and superficial. (c) Phlegmonous Gastritis Phlegmonous gastritis is exceedingly rare. Associated with the grave infections as typhoid fever, smallpox, pyemia, sepsis and abscess, it com- DISEASES OF THE STOMACH 571 plicates already existing serious disease, and adds to the dangers. With puerperal fever and with caustic poisons or erysipelas, the complication is. extremely grave. id) Membranous Gastritis Membranous gastritis is almost always of diphtheritic origin, there- fore, secondary and is exceedingly rare. There may be no subjective symp- toms of stomach invasion or there is pain, tenderness, vomiting, tense abdo- men, particularly in the epigastrium. The heart is rapid and offers the leading prognostic data. The temperature cannot be relied upon because it may not be materially influenced by the complication. The malignancy of the primary infection and general condition of the patient, including the heart, make prognosis certain. In the favorable cases convalescence be- gins with the third week. (e) Toxic Gastritis—Corrosive Gastritis Acute alcoholic gastritis is one of the most frequent of all the diseases of the stomach mucosa. It is simply one of several changes wrought by the poison and with proper care promptly yields to treatment. Most alco- holic toxic gastritis is superficial and catarrhal, is associated with great nervousness—unrest and insomnia—at times albuminuria—but all of these symptoms, unless there are marked depression, heart and other nervous symptoms and lesions, yield. The persistent use of alcohol leads to chronic changes (chronic gastritis). Other poisons which cause gastritis include the mineral acids, alkalis, lead, mercury, phosphorus and arsenic fre- quently. The caustic and corrosive effect of these poisons with the associated shock and kidney involvement often promptly lead to death. In these cases there are deep changes in the mucosa and prompt degeneration of the heart. The decomposition of albuminous substances, either directly or through the circulation, may cause threatening symptoms of toxic gastritis. Alt has attributed gastritis to the excretion of toxalbumins by the stomach in chol- era and Lauder Brunton and Favrer suggested its production by the ex- cretion of the cobra venom. Alt confirmed their suspicion. The vomiting in many general infections may be traced to primary toxemia and secondary gastritis (Brunton). (/) Acute Gastritis with Organic Diseases of the Stomach The presence of acute gastritis with organic diseases of the stomach: during exacerbation is among the possibilities and may account for some of the symptoms which are evanescent. The permanent symptoms are often %n expression of final chronic changes in the mucosa. 572 DISEASES OF THE DIGESTIVE APPARATUS (;g) Acute Gastritis of Fungus Origin Acute gastritis of fungus origin (yeast, anthrax, favus and the Oidium albicans) is only persistent when neglected. The same may be said of gastritis due to the presence of animal parasites. (h) Acute Suppurative Gastritis There are rare cases of acute suppurative gastritis in which there is perigastritis with abscess formation in the'wall of the stomach. The evi- dences of profound pyemia—sepsis—are prominent and death is the rule. With the suppurative there may also he phlegmonous gastritis. Children often suffer from recurring acute gastritis with fever which continues only during a few hours or from one to two days. These attacks are due to faulty diet or other trivial causes in those who are said .to have “weak stomachs” or “poor digestion.” With the advent of the 6th or 8th year the intervals between the attacks grow longer and cease entirely usu- ally after the tenth year. There are adults who are subject to the same acute exacerbations of short duration at long intervals. Cautious differen- tiation is necessary as some of these are due to chronic appendicitis, gall- stones, are of central or spinal origin (cerebral syphilis, tabes dorsalis, etc.). The diagnosis of acute gastritis is not always easy, and prognosis there- fore becomes fallacious. The experiences of the past two decades prove the frequent presence of stomach symptoms “gastritis”—“acute dyspep- sia” in a surprisingly large number of abdominal and other conditions, in which the stomach is absolutely normal. 2. Chronic Gastritis (Chronic Catarrh of the Stomach, Chronic Dyspepsia) Chronic catarrh of the stomach is an inflammation of the mucosa char- acterized by marked increase of mucus, changes in the gastric juice and in the advanced cases hypertrophy of the muscular coat; increasing thick- ening and proliferative change in the mucosa, atrophy of the gastric fol- licles and decided proliferation of the submucous tissue. Polypoid and cystic growth may develop. In some cases there is no hypertrophy of the muscularis but a weakening and dilatation of the wall. In a minority of cases the productive change leads to cirrhosis of the stomach. Cirrhotic Gastritis (Brintons Disease, Linitis cirrhotica) In this form of the disease the interstitial overgrowth predominates, the stomach is abnormally small and there are atrophic changes in the infiltrated mucosa upon which in individual cases multiple polypi may rest. DISEASES OF THE STOMACH 573 Productive change in cases of stomach cirrhosis may cause pyloric obstruc- tion and simulate carcinoma; the cirrhotic stomach may also simulate in- filtrating cancer. The forms of chronic gastritis which we consider are either parenchym- atous, interstitial or there may he mixed types in which lesions are irreg- ularly disseminated and are both parenchymatous and interstitial. There are but few cases of long continued gastritis in which the interstitial changes do not largely predominate and with the advance of the process there is loss of tone, motor insufficiency with final dilatation. We have seen cases in which after years of insult to the stomach the atrophy has been so extensive as'to leave but little remnant of the original mucous membrane (anadenia gastrica). Gastritis may be (a) primary or (b) secondary. (a) Primary gastritis is usually attributable to the patient’s own fault; alcohol, excessive drinking and eating are the leading etiologic factors. Poisons and irritants, improperly prepared food, faulty preparation of the food in the mouth for the stomach (faulty mastication, fast eating) irregularity in eating are also sufficient to start and continue primary gas- tritis. (b) Secondary gastritis depends upon other and primary organic dis- ease of the stomach, cancer, pyloric obstruction and dilatation, long con- tinued atony of the stomach wall and circulatory faults causing chronic enlargement of the mucosa from valvular diseases of the heart, pulmonary diseases (emphysema, chronic pneumonoconiosis, asthma, malignant growth or pressure, etc.). Kidney lesions with chronic uremia (chronic nephritis, etc.), obstruction within the portal circuit, syphilis, pernicious anemia and many other grave primary diseases. In the secondary gas- tritides the added stomach invasion is weakening, often an important factor, though the primary disease usually causes general stasis hence prog- nosis becomes a complex problem but always rests on the paramount influ- ence of the initial and responsible lesion. Often secondary gastritis de- pending on primary incurable disease may improve materially; there may with heart lesions be long periods without symptoms. The gastric features vary as do physical signs and symptoms when the primary condition is in- fluenced by rest and treatment. Cases in which chronic gastritis is associ- ated with or secondary to cirrhosis of the liver may be far advanced in or- ganic change and yet with latency of the latter disease and proper care, life may be made comfortable and indefinitely prolonged. We often find post mortem evidences of both conditions in subjects who had, during many years discontinued alcohol. In chronic gastritis there is usually subacidity though there are cases with normal acidity and as Boas has demonstrated there is a characteristic type in which there is hyperacidity {gastritis acida or hyperpeptica) or hyperacidity may be present temporarily. 574 DISEASES OF TIIE DIGESTIVE APPARATUS The symptoms which predominate comprise the complex of chronic dys- pepsia. I do not consider chronic dyspepsia a disease per se hut always a complex of either primary or secondary gastritis or an accompaniment of other disease with complicating gastritis or faulty gastric function. (The Nervous Dyspepsia of Leube.) The symptoms of chronic catarrhal gas- tritis, including the excessive production and morning vomiting of mucus, anorexia, pyrosis, epigastric pressure, at times pain, persistent nausea, with irregular bowels, coated tongue, all aggravated and continued by the pa- tient’s indiscretions (alcohol, faulty eating, etc.) even in advanced cases, may yield to rational treatment and temperance. It is surprising to note how promptly these symptoms yield. The change does not indicate a return of the gastric mucosa to normal but the insult discontinued, the remnant of tissue with the assistance of the intestinal digestion proves sufficient. The mucus secretion in such cases, particularly the alocholic, will be fairly well controlled. Such cases are always ready to relapse on slight provocation particularly on the return of the original cause. The nervous manifestations in the above mentioned cases are usually as readily controlled as are the other symptoms. The examination of the stomach contents in chronic gastritis is of con- siderable value in deciding upon the type of gastritis present, but for prognosis it offers hut few data save in those forms in which it establishes the advanced atrophy of the gastric follicles and complete anadenia gastrica or achylia gastrica with or without primary constitutional disease (per- nicious anemia, diabetes mellitus). In all of these cases the microscopic examination is important. The presence of nuclei in the epithelial cells is suggestive of acid gastritis (Stockton). The presence of large quantities of mucus in the vomitus or expressed content is not per se unfavorable for the relief of symptoms. The majority of such cases are dependent upon removable causes (alcohol, etc.). Hyperacidity with gastritis acida is at times rebellious to treatment and when relieved tends to recur on cause but in the end it is controlled but only with the assistance of the patient. During the early stage of alcoholic gastritis hyperacidity is frequent. Unless conditions are improved there is progression with gradual reduction of free hydrochloric acid and other evidences of disturbed function, par- ticularly motor insufficiency. The presence of free HCl in the empty stom- ach in these cases often persists during long periods until with the advanc- ing atrophy the acidity falls and there is increase of organic acids (lactic, butyric and acetic). Anadenia or Achylia Gastrica.—The anadenia gastrica of Ewald or achylia gastrica offers evidences of far reaching atrophy with, in most cases, normal motor function. Anacidity in chronic gastritis does not Stomach Contents DISEASES OF THE STOMACH 575 always indicate atrophy of the mucosa for it may he due to gastric neu- roses. Pepsin and rennin are usually present and vary with the free HC1. Single examinations of the stomach contents are not always depend- able. The secretion often varies from day to day and faulty conclusions are reached unless repeated examinations are made. In many, psychic factors are potent in influencing stomach function. There is usually a large psychic element which demands consideration in connection with the examination of the stomach contents in the alcoholic as well as in some cases of gastritis which are of secondary origin. Chronic Gastritis.—The extreme nervous state of the alcoholic with acute exacerbations of chronic gastritis is often controlled with great dif- ficulty. Such patients are usually steady drinkers and not a few develop, wet brain (Alcoholic Meningitis). With the nervous symptoms there may be “stomachal vertigo,” a condition which Trousseau described, patients, fear the “sinking into an abyss” ; vertigo may be of the labyrinthine type; melancholia, hypochondriasis, changed disposition, erratic heart, morning cough, hiccough, dysphagia and asthma with cyanosis may all yield with the improvement following proper diet and abstinence in pri- mary cases and improvement of underlying conditions in secondary gas- tritis. Remissions and exacerbations are to be expected in all forms of primary gastritis depending largely on the habits of the patient. Many alcoholics live for years without subjective symptoms, who finally develop them. Such cases are controlled with great difficulty. The blood picture in those forms of anadenia or complete atrophy may resemble pernicious anemia or with cirrhosis of the stomach and thickening of its coats, with palpable small stomach there may be a strong suspicion of carcinoma. Such cases may, with proper treatment, improve materially for as with all gastritides, however far advanced, the digestive function of the intestinal tract may prove sufficient to supplement the gastric. It will be noted in all organic diseases of the stomach that symptoms are long tolerated without revolt, that digestion proves sufficient to carry the patient along without loss of flesh or many subjective symptoms during long periods while the organic changes are advancing insidiously. The changed and degenerated or infiltrated mucosa in chronic gastritis never becomes normal. It may be so little changed as to cause no serious disturbances. Symptoms may disappear during interminable periods, peri- ods of remission may be short, permanent cure, i. e., regeneration of peptic glands, removal of new connective tissue is not to be expected. Once the subjective symptoms are present they may, in spite of improvement or re- mission be expected to recur on slight cause. Alcoholic Gastritis.—Alcoholic gastritis which has existed during long periods may, after only short abstinence, show marked improvement and 576 DISEASES OE THE DIGESTIVE APPARATUS with continued abstinence may never again give rise to symptoms. The improvement following treatment is promptly manifest in many cases. With motor and absorptive faults and pyloric obstruction from interstitial thickening the dilatation which follows is likely to remain; the general con- dition depends upon the ability of the intestines to supplement the work of the stomach and the direct result of the gastrectasia. The duration of uncomplicated primary gastritis in which the atrophy of the follicles is not too far advanced, and does not progress may be many years. Gastritis without other organic diseases without advanced atrophy, detected early and properly treated, may never give rise to symptoms, in spite of the changed mucosa. The complications of primary gastritis are few and of no prognostic import. The many primary conditions which lead to secondary gastritis are each likely to be associated with conditions which must naturally influ- ence prognosis independent of the existing gastritis. Severe secondary gas- tritis, uncontrollable vomiting, and toxic symptoms sometimes threaten cases in which resistance has been reduced. We have never known death to be due to chronic gastritis alone though the general condition is often below par and efficiency is reduced. I know of no other chronic disease in which rational treatment and the cooperation of the patient in primary cases so promptly and thoroughly control symptoms. Symptoms of "chronic dyspepsia” without stomach lesions may remain uncontrolled and lead to faulty diagnosis in a large number of cases unless great caution is used. Most of these are due to chronic appendicitis, gall-stones, cirrhosis of the liver, or spinal lesions, mainly tabes dorsalis. References Alt. Berl. klin. Wchnschr., 1889. Munch, med.

Dilatation of the Stomach—Gastrectasia According to Ewald the stomach which continually holds more than 1,600 c.c. of fluid is abnormally dilated. Such stomachs are found to hold food longer than seven hours. Dilatation of the stomach may be either (a) acute or (b) chronic. (a) Acute Dilatation of the Stomach My experience with acute distention of the stomach beyond its nor- mal capacity has been limited to its occurrence with chronic disease, acute DISEASES OF THE STOMACH 577 infections and following anesthesia, usually for abdominal conditions. The gastrectasia in all of these cases has been sudden in its onset, has at once been associated with symptoms of failing heart and collapse, vomiting of large quantities of fluid, pinched features and—unless the condition was at once correctly interpreted and treated—death followed. I have found acute dilatation of the stomach an occasional serious complication of pneumonia. If it arises suddenly during the height of the disease it may promptly lead to death. Sudden gastrectasia with pneumonia and chronic valvular disease is usually fatal. Fussell has recently reported his experiences with this dan- gerous complication. In all of Fussell’s cases the autopsy showed con- striction of the duodenum at the root of the mesentery. There is in all probability involvement of the innervation leading to dilatation, this in itself causing by traction a constriction of the duodenum. Fagge’s original description of these cases was based upon his observa- tions in a case in which the patient had overeaten, and with classic symp- toms died in collapse. Connor of Cincinnati reported 102 cases of which 42 followed anesthesia. In the midst of typhoid fever, as in pneumonia or with chronic heart lesions, without added infection, blows upon the abdomen or from any other cause unless the symptoms are promptly re- lieved by lavage of the stomach and stimulation, recovery is exceedingly rare. It is possible for patients convalescing from acute infections to sud- denly fall into collapse from dilatation of the stomach, when with peristaltic unrest, marked splashing and collapse with all of the usual physical signs, their lives are threatened. Relief must be prompt, for unrelieved, death follows in a few hours. We have had no experience with suddenly arising dilatation in spinal disease. Connor’s cases showed the usual high mor- tality, practically 75 per cent. The prognosis is favorably influenced by the early lavage and turning the patient on the side to encourage the emptying of the stomach. The latter maneuver alone (without lavage) is of little value. Of 31 patients treated with medicine alone without posture or tube, 29 died; in 142 cases after operation the mortality was 54.9 per cent according to Borchgrevink, who found that in 70 cases treated with the tube and following Moynihan’s advice to turn the patient on the right side, the mortality was 26.9 per cent. Meltzer suggests that the dyspnea with frequent swallowing of air without saliva may be a factor in the production of the dilatation. (6) Chronic Dilatation Chronic dilatation of the stomach is rarely primary; when it is, it may he characterized as myasthenic or atonic, and according to Boas represents “motor insufficiency of the first degree Primary myasthenic dilatation is usually due to the patient’s own fault—errors of diet, fast and in- 578 DISEASES OF THE DIGESTIVE APPARATUS ordinate eating, the excessive drinking of fluids (alcohol, beer, tea, coffee and water). There are primary myasthenic dilatations which are con- genital; families are found in whom all members are afflicted. Dilata- tion which is chronic and due to myasthenia or atony, may be materially improved by treatment, but it is likely to recur and often leads to continu- ous ill health and persistent dyspepsia. When due to nervous influences which can be controlled unless the stomach wall is abnormally thin and the condition of long duration, the prognosis is good for the relief of symptoms but more or less dilatation usually remains. Enormous and unexplained gastrectasia is often found in the insane, with wasting diseases, diabetes, and in tabetics. Atonic dilatation which can only be explained on the theory of myasthe- nia without organic change, is often associated with nervous symptoms which are persistent and exceedingly annoying. They often include the complex of neurasthenia and in women, oftener than in men, continue un- influenced by any treatment. In both there is a large element of sugges- tion which continues and is responsible for many of the subjective features. Stomachal vertigo (Trousseau-Friedenwald) is exceedingly annoying in this form of dilatation as it is in chronic gastritis. It is unquestionably of toxic origin. Boerhave recognized it; Trousseau first described its leading features; Boas, Eriedenwald and Pick have all insisted on its toxic origin. The observers mentioned in the preceding paragraph found atony of the stomach and intestine the leading cause of stomachal vertigo. Enor- mously large stomachs—gastromegaly—may continue unchanged through- out life, without causing symptoms. The motor and digestive functions remain undisturbed. Secondary Chronic Dilatation Dilatation of the stomach which is secondary and chronic is dependent upon obstruction. The obstruction is either benign or malignant. There are a number of extragastric lesions which by compression or traction lead to secondary dilatation of the stomach. Whenever from any cause there is constriction of the pylorus, the stomach wall makes an extra effort to empty the organ and hypertrophy of the muscularis results, and with moderate non-malignant disease, may, during unlimited periods prove sufficient, giving rise to no or few symptoms. When the stomach is forced to overcome increasing obstruction, its musculature suffers; degenerative changes may follow in its wall; there is increasing consecutive dilatation. The degree and amount of secondary change depend entirely upon the extent and nature of the obstruction. If the obstruction cannot be over- come by mechanical or surgical means, complete insufficiency follows, and the stomach is continuously distended with undigested and irritating solid DISEASES OF THE STOMACH 579 and liquid food. With these cases the toxic and nervous symptoms are in the ascendency and long periods of ill health and the neurasthenic complex are thereby explained, though not always relieved. In all of these cases lavage is likely to relieve the subjective complaints; unless the primary cause can be removed or overcome, subjective and objective manifestations can only be treated symptomatically. These cases when neglected may develop tetany which is always threatening, demand- ing immediate care. Lavage may prevent the spasms during unlimited periods (See Tetany). There are chronic cases in which changes of a degenerative character or inflammation secondary to serious constitutional anomalies lead to muscular insufficiencies and consecutive dilatation. Such cases are not materially influenced by treatment. The organic constriction at the pylorus, either intra- or extragastric, produces motor insufficiency of the second degree and provokes persistent symptoms of dyspepsia. The prognosis of secondary dilatation of the stomach can only be of- fered with the separate consideration of the responsible lesions. The chapters which follow (Benign and Malignant Stenosis of the Pylorus, Ulcer of the Stomach, etc.) offer the necessary data which justify the forecast. Boas. Diseases of the stomach.

Gastroptosis—Enteroptosis (Glenard’s Disease, Visceroptosis) Glenard’s disease is a condition in which there is ptosis of the abdom- inal viscera, gastrectasia, gastroptosis, enteroptosis, often prolapse of the liver and spleen, with—in a large number of cases—mobile kidney. There is, in most cases a train of prominent nervous manifestations, often but few gastro-intestinal symptoms. The neurasthenic complex is always in the ascendency and is the leading feature, besides the physical signs of the disease. While incorrect dress (lacing, etc.) may increase prolapse in individual cases, there is, as a rule, a predisposition to Glenard’s dis- ease and this is greatest in the children of neurotic parents, themselves 580 DISEASES OF THE DIGESTIVE APPARATUS nervously overwrought. Any anomaly which removes the normal support of the abdominal organs—child-bearing, laceration of the perineum, injury to the abdominal wall, ventral hernia following laparotomy, abnormal “ligamentous and cartilaginous support” (Stockton)—may lead to pro- lapse of the abdominal viscera. The congenital loose attachments of the mesenteric and peritoneal supports are leading features. Stiller has demonstrated the absence of the tenth costal cartilage in a large number of cases of Glenard’s disease. We have been surprised by the frequency of this anomaly, the marked and persistent neurasthenia in such cases. The absence of the normal dorsolumbar curve is considered by R. R. Smith as a leading feature of enteroptosis, and both Smith and Goldthwait agree that the condition is of hereditary origin. Great caution in diagnosis is necessary, for Rontgen pictures have proved the fact that most adults have more or less enteroptosis and we are of the opinion that too many x-ray pictures are faultily interpreted to the injury of the patient (Holzknecht-Groedel). We are fully agreed with Stockton who in his recently published works says “ . . . insufficient value is attributed to the effect of gravity in dragging down viscera weighted with bismuth.” We are fully convinced that cautious physical examination of the abdominal viscera offers the most valuable data for diagnosis and prog- nosis which should in doubtful cases be confirmed by the Rontgen rays, but the latter need interpretation by the specialist who is not biased by preconceived notions or uncertain theories. We have, in lean subjects, frequently obtained valuable data from inflation of the stomach and rectum with carbonic acid gas or air. Auscultatory percussion is also of great value. Splashing is a symptom of value only as it is considered with other physical methods and x-ray in doubtful cases. The most difficult cases are those in which without cause, save inherent defects, we find the fully developed Glenard’s process with overpowering neurasthenia, at times psychoses, which are borderline; in all an overpowering autosuggestion which holds the patient without thought of anything but self. Often there are imperative conceptions which make life almost unbearable. Mobile kidney is as a rule a permanent defect and in most cases causes no symp- toms ; its presence when disregarded or unrecognized by the patient will be well borne during years, often forever. Treves, with others, has found that the larger number of “anchored” kidneys finally loosen from their moorings and are, after a few years, as movable as before. There are exceptions but they are few, and the con- sensus of opinion today favors support without operation. DietVs crises are exceedingly painful and when frequent may interfere with the general health of the patient besides leading to morphinism. These cases are favorably influenced by mechanical treatment or radical surgical operation. DISEASES OF THE STOMACH 581 The twisting of the ureter may cause repeated intermittent hydro- nephrosis, not a serious complication, for with positive diagnosis and surgical treatment, after scientific differentiation (cystoscopy, uretero- scopy) the condition may be overcome. The functional tests should in- clude the consideration of both kidneys. The circulation is often erratic and functional disturbances are not unusual; there may be palpitation and arhythmia with, in some cases venous engorgement. Many of these symptoms are promptly relieved by support or postural treatment. They return on slight cause. Chronic constipation is the bane of these cases and cathartics are taken by the majority. Support, diet and rational treatment improve many of these. The prognosis so far as life is concerned is always good ; the neuras- thenic symptoms in uncontrolled cases (usually in women, though men are frequently included) are likely to persist unchanged until after the years of greatest sexual activity, after which we have found enormous improve- ment. The element of suggestion with proper support, right living and occupation, are the paramount factors which influence the lives of these patients (See Neurasthenia). Glenard (F.).

The malignant stenoses of the pylorus are consid- ered with cancer of the stomach. Benign Stenosis of the Pylorus Benign stenosis of the pylorus may he either (a) functional or (b) organic. The latter may be (I) congenital or (II) acquired. Functional stenoses are found in the highly neurotic, and are transi- tory. Pyloric spasm may be chronic and lead to gastrectasia with intol- (a) Functional Stenosis 582 DISEASES OF THE DIGESTIVE APPARATUS erant stomach, peristaltic unrest and hyperacidity. These patients are made worse by mental distress; they are often neurasthenic. While the spasm does not continue indefinitely, the gastrectasia may persist and the spasm is likely to recur on slight cause. Intermittent hyperchlorhydria without ulcer may cause pyloric spasm and temporary obstruction; in such cases the pains (always present), large fluid hyperacid vomitus, severe headache and other cerebral symptoms, yield to proper treatment. The symptoms persist until the hyperacidity is overcome. Acute dilatation depending on transitory causes (obstruction due to traction) has been separately considered (See Gastrectasia). Pyloric spasm may be safely considered secondary in most cases, and its presence should lead to a strong suspicion of organic disease. In young neurotic girls pyloric spasm may be associated with moderate gastrectasia, and there may he peristaltic unrest, painful cramping of the stomach, with or without vomiting. With increasing methods of precision, functional stenosis of the pylorus will be found less frequent. (b) Organic Stenosis (1) Congenital Stenosis of the Pylorus If congenital stenosis is of moderate degree, manhood may be reached in comparatively good health; nature may compensate for the defect, the stomach musculature increasing and digestion continuing practically normal (compensatory hypertrophy). Serious congenital stenosis proves its presence in symptoms before the fourteenth day—never after the ninth week—and death follows before the fourth month unless the infants are relieved by surgical interference. Cases which appear extreme may (rarely) yield unexpectedly. One of our cases, with symptoms beginning at birth, in which the child during the first two years of life presented all of the symptoms of congenital stenosis (before the days of the x-ray), has grown to manhood, perfectly well. When this boy was one year old he weighed less than he did at birth. Persistent vomiting in children beginning after the ninth or tenth week of life, is not due to congenital narrowing of the pylorus, and offers a better prognosis than does the vomiting of stenotic origin. Most children with congenital stenosis die before the end of the third or fourth month. No possible modification of the food relieves the symptoms when the stenosis is of high degree. Congenital incomplete stenosis of the pylorus causes chronic disturbances which continue throughout life. Stagnant food is always present in the stomachs of these patients. Dilated stomach persists in spite of well regulated treatment, lavage, etc. Gastric fibrosis of Ilanot or the hypertrophic pylorus of Cruveilhier DISEASES OF THE STOMACH 583 and Andral are sequelae which materially influence the size and position of the organ. (II) Acquired Stenosis—Intrapyloric 1. Chronic Cicatricial Stenosis.—The majority of benign stenoses are due to ulcerative processes invading the pylorus. Ulcers may exist with- out causing symptoms; usually the history is direct and convincing. Cicatricial contraction follows slowly; in many there is the history of hemorrhage. The stomach contents, the x-ray and the tube confirm the dilatation and primary lesion. Phlegmonous sloughing due to corrosive poisoning and contraction cause dilatation. The prognosis in otherwise normal adults is excellent following surgical interference. 2. Fibrotic Stenosis.—(a) General Stenosis.—General stenosis was de- scribed by Brinton and Hanot (See also Brintons Disease or linitis plastica or cirrhosa). The change is far-reaching in the mucous and sub- mucous coats of the stomach, invading the pylorus as the process advances, leading to marked contraction and thickening of the entire organ with al- most complete closure of the stomach outlet. Pernicious anemia may be simulated—also cancer. Surgery offers the only hope of relief in extreme cases. (b) Localized Stenosis. Localized fibrous thickening of the pylorus is likely to be annular. Previous limited ulceration may be the cause. Ring-shaped constriction causes consecutive dilatation. These cases are also favorably influenced by radical treatment. 3. Hypertrophic Stenosis of Cruveilhier.—Hypertrophic stenosis of Cruveilhier fully described by Boas, follows chronic gastritis; there is ultimate dilatation. The prognosis depends upon the general condition of the patient and the ability, if the symptoms are threatening, to with- stand surgical interference. Most cases are not so extreme that they demand radical treatment and may live for years without it. 4. Stenosis Dependent upon Active Ulcer.—Ulcer at or near the pylorus and in the first part of the duodenum with associated spasm, marked swelling which may be acute or due to secondary inflammation, is an occasional cause of pyloric constriction and offers a good prognosis. 5. Acute Inflammatory Stenosis.—Acute inflammatory stenosis asso- ciated with infection, deep seated gastritis and acute poisoning may sub- side unless the changes are sufficiently deep to give rise to permanent lesions (Eisner). 6. Syphilitic Stenosis.—Syphilitic stenosis is occasionally found; when extreme and the treatment radical, improvement may follow. Syphilis is a frequent cause of stomach symptoms which are transitory, disappearing on treatment, but if secondary dilatation follows it remains but little influenced. 584 DISEASES OF THE DIGESTIVE APPARATUS 7. Tuberculous Stenosis.—Tuberculous stenosis is rare and is not lim- ited. The process is far-reaching and involves the entire stomach. 8. Stenosis dependent upon non-malignant growths, fibromyoma, ade- noma and polypi may prove puzzling; they are rare and are diagnosticated either during surgical interference or post mortem. 9. Stenosis due to distortion or traction causing acute pyloric ob- struction (Kussmaul, Aufrecht and Riegel), dragging at a point in the horizontal part of the duodenum, is practically identical with acute dila- tation already considered. These cases are always serious (mortality 75 per cent). (See Acute Dilatation of Stomach.) Extrapyloric Stenosis “It is difficult to divine all of the unusual and unexpected conditions which may lead to extrapyloric organic stenosis” (Eisner). The leading extrapyloric lesions which constrict the pylorus are: perigastritis, gall- stones, adhesions to neighboring organs—particularly to the liver and gall- bladder—distortions due to innumerable anomalies and pathologic changes invading the organs already mentioned, also the pancreas and kidney. The pylorus is constricted, and motor insufficiency with dilatation results. We have reported monstrous gall-stones which by pressure and adhe- sions caused stricture with symptoms of cancer (Eisner). It is at times exceedingly difficult to recognize the cause of extrapyloric stenosis; in the majority of cases diagnosis and prognosis are possible and with modern surgical technique the cause is often removed. Each case demands sepa- rate consideration that the underlying cause may be discovered and con- sidered. In the prognosis of pyloric stenosis we must cautiously differentiate benign and malignant disease. The diagnosis of constriction must always be suspected when the fasting stomach is distended and contains food. Food remnants after seven hours prove motor insufficiency and suggest obstruction. The obstruction creates a decided disproportion between the stomach's taste and its ability to perform its duty (Riegel). Dangers from tetany are separately considered (See Tetany). With advancing disease the heart may become ungeared; it influences the length of life in cases which are not amenable to surgical treatment. The stomach content which shows gradual loss of HC1 from time to time with the addition of organic acids as the free ITC1 disappears, evidences of fermentation must lead to a strong suspicion of malignancy and argues against benign disease. Large quantities of indican in the urine and an abnormally high urea output are suggestive of malignancy, and argue against benign constriction. X-ray examination proves exceedingly valuable, for it localizes lesions, outlines the stomach, and with the results of thorough physical examination DISEASES OF THE STOMACH 585 and the chemical analysis of the stomach contents makes a forecast reason- ably certain. With incomplete obstruction, persistence, prophylactic treatment and diet, will often hold the disease without advance. Diet requires special care, because of the weakened motor function and obstruction, that food may be forwarded beyond the point of resistance for further digestion. If this can be accomplished, life may be prolonged many years in the absence of complications. The prognosis is improved in proportion to the ability of the attendant to prevent stagnation and the formation of organic acids. This means that the distended stomach must be assisted, so far as it is possible, to empty itself. In no other disease of the stomach will detail and clear judgment with the full appreciation of the primary cause of the stenosis accomplish so much. References Andral.

Gastric and Duodenal Ulcer (Ulcer of the Stomach, Peptic Ulcer, Round Ulcer of the Stomach') Symptoms.—Round ulcer of the stomach is characterized by circum- scribed loss of the mucosa, which when it becomes chronic shows but slight tendency to heat. History.—Our first conception of the disease dates from 1829 when Cruveilhier fully described it. The early literature is most interesting and proves how full was the knowledge which the clinicians possessed before our modern refinements of diagnosis were introduced. Following Cruveil- hier, Rokitansky, the great pathologist at Vienna (1804-1874), wrote a classic treatise on ulcus ventriculi. Virchow in 1853 advanced the theory that the break in continuity of the mucosa depended upon a quantita- 586 DISEASES OF THE DIGESTIVE APPARATUS tive anomaly in the elaboration of free hydrochloric acid caused by vagus disturbance and that the circumscribed ulcer (limited) was associ- ated with a local anomaly with the choking of the circulation. In 1858 Brinton’s work appeared; Trousseau in 1860 followed and prepared the foundation for rational medical treatment; the same year L. Miller, a practicing physician in Minden, published as Leube says, the best treatise which we possess on the disease; 1864 brought Bamberger’s work, 1878 Lebert’s. Later Leube proved the overpowering influence of rest, diet, and rational treatment in the majority of cases, since which time the works of Riegel, Ewald, Boas, in Germany, in the domain of medicine, the Mayos, Rodman, Musser, Stockton, Jacobi in America, Robson and Moynihan in England, stand out in bold relief among the thousands of contributions dealing with the surgical and medical prob- lems, many of which are still unsettled. All of this activity has led to many positive conclusions—better than all else, to the saving of human life because of our appreciation of the dangers of complications and sequelae, and their conservative, often radical attack. General Considerations.—The forecast of stomach ulcer depends upon its type and depth, the local secondary changes, the resistance, the blood state, the complications, and the time when treatment (dietetic, medical or surgical) is instituted. Aschoff’s hemorrhagic erosions cause small multiform tissue loss; the erosions are round and sharply defined, usually located in the fundus; there are but few or no lesions at the pylorus. These hemorrhagic ulcers were supposed to be of embolic origin, but in the light of recent experiences this theory has been questioned. Septic and fat emboli may certainly cause hemorrhagic infarct, and venous emboli (Aschoff) have been considered. Hemorrhagic erosions are rarely found in adults, almost always in in- fants. When found in the adult they follow abdominal operations; they may cause subjective symptoms during a short time preceding death. Their formation is usually a terminal feature. The loss of blood connected with hemorrhagic ulceration is not large and is not a factor in prognosis. The infection or toxemia in these cases remains the prominent feature. Large hemorrhage into the mucosa may in the adult lead to acute mul- tiple ulcers in the fundus and at the pylorus. The posterior wall is their favorite seat. Fatal hemorrhage even from small ulcers is possible; the stomach is filled with blood and the ulceration is found to be deep, not simple as in the cases considered in the previous paragraph. These cases jare in all likelihood mycotic; they may follow traumatism, thrombosis (secondary to coronary thrombosis, to gall-bladder infection, thrombosis of the cystic vessels or embolic closure of the artery). With arteriosclerosis and nephritis, acute ulcer of the stomach has formed (Hauser, Ophuls). Whatever the method of formation, the majority of acute ulcers heal leav- ing sufficient evidences to prove that possibility in the light colored cica- DISEASES OF THE STOMACH 587 trix, usually superficial, which rarely causes secondary motor insufficiency or stenosis. In a 'proportion of cases the chronic round ulcer results from the acute. Aschoff makes the positive statement that “the chronic ulcer almost always originates after an acute defect.” The question, therefore, is not how does a chronic ulcer originate but under what conditions is the “acute defect” transformed to produce it. Between 85 and 90 per cent of chronic ulcers are found at or near the pylorus. The duodenal ulcers are near the pylorus in the first and second portion of the duodenum. Twenty per cent of Mayo’s cases in- volved the margin of the pyloric ring. The thorough observations and recorded experiences of surgeons dur- ing the past decade, particularly those of the Mayos, Moynihan, Deaver, Robson and others, who have had control of an enormous material which has been scientifically examined and treated, have revolutionized our ideas concerning many points bearing on diagnosis, prognosis, and rational treat- ment of all necrobiotic processes leading to gastric or duodenal ulcer. Facts Which Influence Prognosis.—The theories which have been en- tertained in the past concerning the formation of the ulcer have received a severe shock from the experimental work of Rosenow, Rosenau and Ander- son, which tend to prove that ulcer is of infectious origin. For our pur- poses in considering the prognosis of both gastric and duodenal ulcer it would be a work of supererogation to consider the many theories which have been advanced. We can only base our prognostic data on incon- trovertible facts and these prove that: (а) Ulcer of the stomach is most frequent in anemic or chlorotic women, between the ages of 20 and 40. Sixty per cent of all stomach ulcers are found in women. In these young subjects the stomach mucosa heals readily after injury or abrasion and simple uncomplicated ulcer is likely to heal. The older subjects are much more liable to relapse as the reparative powers are more feeble. (б) While the experiments of Rosenow point strongly to the infectious origin of ulcer, we are not yet ready to accept that theory without ques- tion—neither is he—but agree that ulcer of the stomach is always asso- ciated with an acid condition, usually hyperacidity (Ewald). There may be subacidity. (c) Ulcer of the stomach is a condition which may exist without caus- ing subjective symptoms; such ulcers may heal and the cicatrices are found post mortem in which death was due to some other disease. This fact has been fully corroborated by the observations of Welch who in a large mate- rial found that in at least 5 per cent of all deaths there are evidences of ulcers or cicatrices of old and healed ulcers. (d) The relative frequency of gastric and duodenal ulcers has only recently been recognized. Gastric ulcer is more frequent in females. The 588 DISEASES OF THE DIGESTIVE APPARATUS Mayo material and that of Moynihan and other observers proves that relatively duodenal is more frequent than is gastric ulcer, and that duodenal ulcer is more frequent in males—77 and 23 per cent respec- tively. (e) Exceedingly important for diagnosis and prognosis is the estab- lished fact that a surprisingly large number of hyperchlorhydrias are symptomatic (possibly provocative) of peptic and duodenal ulcer. (/) Large surface burns may he followed by duodenal ulcer. Our ex- perience proves that this is more frequent in children than in adults, that burns with such complications are almost always fatal, that perforation is not frequent but possible. (g) Duodenal ulcer is a relatively frequent complication of chronic nephritis, and in two of our cases perforation offered the first evidence of its existence. In some cases the symptoms of duodenal ulcer are in evi- dence during long periods preceding death from the primary disease, with or without uremia. One of our cases, a physician, with chronic interstitial nephritis, died of perforation with consecutive subphrenic abscess over three years after his initial symptoms of ulcer. (h) Indicanuria does not influence the prognosis. In some cases of duodenal, occasionally with gastric ulcer, we have found it; with perfora- tion indicanuria is usually positive and is simply one of many symptoms, which, if taken alone does not materially influence the forecast. (i) Peptic ulcer may cause proliferative changes, induration simulat- ing carcinoma—life may he but little influenced unless there is pyloric constriction or other complications. (/) Periods of remissions of symptoms without the healing of the ulcer are to he expected in most chronic cases. The presence of an unhealed ulcer, either of the stomach or duodenum, is always a menace. Such a life is subjected to a number of dangers which without warning may, within a limited period, end it, though the proportion of deaths due to such possi- bilities is comparatively small. About one-half of all cases will either suffer from recurring attacks or have continuous symptoms. Between 6 ,and 10 per cent will remain in an uncertain state between recovery and more or less ill health. (Jc) The chances of chronicily and marked resistance to medical treat- ment are almost certain if two or more relapses have been experienced. Our material demonstrates the fact that while the large majority of these do not die directly as the result of the ulcer, they continue unhealed, and' with such a history many finally face some one or more of the leading dangers as mentioned below. (1) Freedom from symptoms during long periods does not by any means signify cured or healed ulcer. Failure to recognize this fact with result- ing carelessness may provoke one of the grave complications. So long as occult blood is present in the stool, the ulcer is not healed DISEASES OF THE STOMACH 589 and the dangers of complications exist. A single examination is insuffi- cient, for blood may be absent during limited periods from the stool. (m) Vomiting.—The majority of our cases have had irritable stomachs and have often presented with vomiting that has been neglected; most of these cases are relieved by treatment. We do not include a single in- stance in our series in which life has been lost as the direct result of pro- longed vomiting. Cases in which there has been a long period of vomiting with sudden serious complications have had lowered resistance, and re- covery was slower than it would otherwise have been. Vomiting is less frequent than one would expect; when it does occur it is likely to recur and continue several days. The vomiting is often paroxysmal; with stric- ture and dilatation large quantities are vomited at one time at varying intervals. (n) Examination of Stomach Contents.—The examination of the stom- ach contents and the influence of diet and treatment upon hyperacidity where it exists, have an important bearing on the clinical history. Cases in which the excessive production of HC1 persists, in which there is almost continuous hyperacidity, often hypersecretion, do not heal as a rule. The more favorable cases for relief of symptoms are those in which there is but slight hyperacidity or in which the symptoms yield to diet and treatment. It will require great caution to interpret the results of chemical analysis of the stomach content in anomalous cases. There are peptic and duodenal ulcers in which there is normal or slightly reduced acidity; cases in which there are exacerbations and both hyperacidity and hypersecretion, and a small class in which with loss of flesh and gradually increasing evi- dences of cachexia, the acidity falls and lactic acid appears. In this class of cases the development of cancer in the base of the ulcer should be strongly suspected (ulcus carcinomatosus). Gastrosuccorrhea {Reichman’s disease) should always excite the suspi- cion of ulcer. Usually it will be found at the pylorus; it may be anomal- ously located. It is a question whether with reduced resistance and chloro- sis, long continued hyperacidity and hypersecretion may not cause ulcer. (o) X-ray Pictures.—Rontgen rays are of value for diagnosis; for prognosis they offer but little. Both diagnosis and prognosis can be placed on a solid foundation without the aid of the x-rays, but in doubtful cases, as well as in those cases in which the examination can be made without risk to the patient (transportation, etc.) it should be included in the scientific examination of the patient. X-rays will estab- lish the presence of the hour glass stomach, will make clear secondary gas- trectasia, may aid in the early diagnosis (should not be depended upon without other clinical data), will often show hypermobility with ulcer; but hypermobility is not a constant attendant. With duodenal ulcer there is likely to be pyloric insufficiency (Bergman, Friedenwald and Baetjer), causing a prompt discharge of the bismuth into the duodenum 590 DISEASES OF THE DIGESTIVE APPARATUS and the ulcer showing as a small clear spot. Others, including Cole, re- port the duodenal cap in position, more or less contracted, a “wormeaten” appearance with the duodenal surface of the pyloric sphincter irregular. Stockton in his recent works says “the radiographic evidence of duode- nal ulcer has not yet reached sufficient perfection to. warrant making a diagnosis on it alone.” Complications The leading complications and dangers are: 1. Perforation 2. Hemorrhage 3. Degenerative changes leading to cancer of the stomach 4. Cicatricial distortion and stenosis 5. Perigastric adhesions 6. Exhaustion .7. Parotitis (metastatic). 8. Tetany 9. Acidosis. 1. Perforation. Perforation at once makes the case surgical. The full appreciation of this fact will save many lives. The prognosis of per- foration depends upon many conditions. While perforation is the most fatal of all the complications of ulcer of stomach and duodenum, it is a fact that in occasional and rare instances nature’s protective processes, the unusual resistance of the patient or some factor unknown, may lead to recovery. The busy internist may have two or three such experiences in a life time; they are indeed so rare and unusual as not to he expected and ought not to encourage the attendant in unwarranted delay. One- half of all perforations in women occur between the fifteenth and thirty- fifth year, one-third about the time of puberty (14 to 20). In men there is no time of predilection up to the fiftieth year (Craemer). Perforation is more frequent in men than in women, particularly with duodenal ulcer. Musser in his collective investigation found 28.1 per cent of 1,871 cases with perforation. This is much higher than our statistics from private practice. The German average is in the neighborhood of 13, Lebert and Welch 3 to 6, Leube in 1.2 per cent. Perforation may be either partial or complete. The perforation may be prevented or be incomplete leading to localized perigastritis or limited peritonitis if the adhesions are sufficiently firm to protect the free perito- neum. Brinton in 1858 called attention to the fact which has since been confirmed that most perforations are found in the anterior wall (70 per cent) ; they are unprotected and complete, and there is resulting general peritonitis. This is particularly true of the acute ulcer. The chronic ulcer DISEASES OE TIIE STOMACH 591 (Dreschfeld) usually perforates in the region of the pylorus, “on the posterior wall and near the lesser curvature.” The prognosis of perforation of the stomach wall will always be favor- ably influenced by the physician’s ability to make the correct diagnosis suf- ficiently early (during the first five hours preferably) to lead to imme- diate surgical action. Here we have the “acute abdomen” in which there is but scant hope of saving life without radical interference. The opera- tion within the first five hours offers enormous advantages and in the hands of most surgeons, unless there are associated conditions which in- terfere, recovery may be expected. The forecast is quite different in cases in which diagnosis and operation are delayed beyond the fifth hour. When the abdomen is tense and hard, the pain severe, vomiting persistent, hic- cough, rapid and feeble pulse, reduced urine, blood pressure low after an initial slight rise which usually follows perforation, the prognosis is ex- ceedingly grave and such cases are rarely saved. When the perforation has existed beyond the time mentioned (10 hours) the features are pinched, the heart rapid, vomiting often fecal, symptoms of extreme toxemia are prominent; neither surgical nor medical treatment offer much chance of recovery. In apparently perfectly healthy individuals, without a single warning of existing ulcer, perforation may occur and in those above fifty years of age, death may follow within the first few hours, with collapse, before peritonitis develops. If the perforation is small or incomplete and pro- tective localized peritonitis seals the opening, recovery will be likely to follow. Such cases are unquestionably more frequent than is generally supposed and post mortems have demonstrated that fact in those who finally died of other disease. Adhesive perigastritis agglutinating the transverse colon to the stom- ach wall may serve to protect the peritoneum when perforation takes place, and gastrocolic fistula may result. This is always a serious, but not neces- sarily fatal, complication and may be relieved by plastic operation. With duodenal ulcer, subphrenic abscess may form, and this without general peritonitis. Perforation from subphrenic abscess into the pleura, lung, or surrounding organs is a serious complication—the early recogni- tion of which may save life. Only rarely does the condition yield with- out surgical intervention. We have seen two cases. One was associated with metastatic parotitis and finally made a slow recovery. The other lived through peritonitis and is now perfectly well so far as we know. In this case, the dense adhesions due to perigastritis saved the man’s life. The operation for subphrenic abscess dependent upon perforation is en- couraging. Elsberg reports 13 cases—51 were operated and 40 recovered, 18 of 22 not operated died. Perforation into the pleural cavity or heart sac, into the lung or after long burrowing through the abdominal wall may lead to long periods of 592 DISEASES OF THE DIGESTIVE APPARATUS convalescence, or the patient may, after weeks of symptoms die of sepsis. The heart wall (left ventricle) has been perforated after burrowing, in which the pericardium was naturally first perforated. The recognition of perforation is not difficult in cases which have offered preceding symptoms of indigestion or ulcer. The "acute abdomen” should be suspected to be due to perforation of the stomach in all cases in which there has been hematemesis, localized pain or other symptoms of ulcer, with the characteristic behavior of the stomach contents (hyperacidity, etc.). There is no abdominal condition which causes such intense pain, none in which the collapse is more prompt, none in which the physical signs of peritonitis during the early hours are more prominent, and none in which the heart muscle yields more promptly to the resulting toxemia. All of these conditions which mean death, are fortunately less frequently met because of unanimity of opinion by which such cases are immediately re- ferred to the surgeon. Musser agrees that “the best percentage of cures was noted when operation was between one to twelve hours after perforation.” Statistics concerning the results of the medical and surgical treatment of perforation are of little value, and are best omitted because they cannot possibly be based upon premises which are the same in all cases. We do know that almost all die who are not surgically treated. We conclude as we commenced the consideration of this accident that perforation is at once a surgical affair, that delay, failure to recognize the cause of the suddenly arising and severe symptoms causes death; correct and early diagnosis, other factors being favorable, is very likely to save life. Recovery after operation for perforation of either gastric or duodenal ulcer is less favorable in cases with long existing dyspepsia than with a short history of digestive disturbances. The chronic cases with repeated acute exacerbations are found with annoying and complicating adhesions and often troublesome thickening. The “acute abdomen” from whatever cause, is serious; the future clinician will meet fewer cases, for experi- ence has grown and the causes which produce it are recognized by the acute diagnostician to receive timely treatment. Mayo (W.) places the conditions which lead to the acute abdomen in the vast majority of cases in the following order of their occurrence: 1st. The appendix. 2d. The duodenum. 3d. Acute pancreatic fermentation. 4th. Perforation of the stomach and of the gall-bladder. 5th. Pelvic conditions which simulate thrombosis of the mesen- teric vessels. 2. Hemorrhage.—My experience has brought the usual proportion of ulcers of the stomach but I have lost surprisingly few patients from hemor- DISEASES OF THE STOMACH 593 rhage. Small hemorrhages, or vomitus mixed with blood, are frequent; large hemorrhages are rare, occult blood is practically a constant feature; bloody stools wfith duodenal, at times with gastric ulcer are to be expected. Statistics are again fallacious because there is no standard of comparison, and those who offer high percentages probably include blood streaks, etc. Welch reported death from hemorrhage in 3 to 5 per cent; Miller in 10 per cent; Muller (L.) in 29 per cent; Ewald and Leube in 1 per cent; and Jacobi’s experiences correspond closely with the latter figure. The frequence of hemorrhage is in the neighborhood of 50 per cent. Leube reports 46 per cent. Fenwick reports 75 “ “ Rutimeyer reports 71 “ “ Brinton reports 29 “ “ Beyond 50, with high arterial blood pressure and degenerated arteries and gastric ulcer, there may be uncontrollable and fatal hemorrhage. The average mortality from hemorrhage in private practice will not he found above 2 per cent; in hospital practice it may approach a higher figure— 6 to 8 per cent. Repeated hemorrhages with acute exacerbations in chronic cases are ominous. We have seen a number of cases in which there were long periods of remission of all symptoms, in which with recurrence there was the usual localized pain and immediately profuse hemorrhage. Such cases (rare) are likely if they are not treated surgically, during the inter- val, to bleed to death ultimately. In the hemophilic the prognosis is naturally worse. We cannot too forcibly impress our readers with the great importance of appreciating the prognostic meaning of hemorrhage in this class of cases. Hemorrhage in some chronic cases may prove persist- ent and causes profound secondary anemia; such cases ultimately prove to he surgical and after a period of reconstruction during a favorable inter- val, are usually saved by surgical interference. It does not often happen that the initial hemorrhage is sufficiently profuse to deplete and cause death. Such an experience we had only once in a woman of thirty who, after a few days of localized pain and overeating, died within twelve hours following a profuse hemorrhage. 3. Degenerative Changes Leading to Cancer of the Stomach.— When we consider the different opinions and statistics of able clinicians and pathologists relating to degenerative changes, we are forcibly re- minded of the fact that the study of gastric and duodenal ulcer offers a series of contradictions. Zenker in 1882 held that all cases of cancer of the stomach had their origin in simple ulcer. Hauser in 1883 first pointed out histologically the transition of ulceration into carcinomatous proliferation. Haberlin found 594 DISEASES OF THE DIGESTIVE APPARATUS evidences of carcinomatous degeneration in 7 per cent of all ulcers; Miculisz in 7 per cent; Lebert 9 per cent; Rosenheim 6 per cent; Fenwick 3 per cent; Osier 26 per cent; Moynihan 60 per cent; Mayo 54 per cent; Graham 62 per cent; Wilson and MacCarty 71 per cent. Rosenheim came to the conclusion that about one in 15 cases of stomach ulcer develops cancer. Einhorn holds that no one who has had a large experience has found it a frequent occurrence. “This coincidence is so small, cancer being such a frequent malady, that it is doubtful whether ulcer plays a part at all in the development of cancer.” Payr’s material of excised ulcers showed cancerous infiltration in 26 per cent. Borrman in a very exhaustive article on the method of growth and dissemination of cancer of the stomach found in 63 cases of ulcer but one in which cancerous degeneration was proved to be present. Reim- ers, Haberlin, Sonnischen, Haberfeld and Dittrich offer figures between 6 and 22 per cent. Futterer has seen 52 cases in which ulcer led to cancer. Rippert quotes Hirshfeld as saying “the processes are mere coin- cidence.” Borst believes the ocmirrence is overestimated—he found 5.6 per cent. Wilson, at the Mayo Clinic, in 258 cases of cancer of the stomach found 109 to proceed from ulcers. Friedenwald has made an exhaustive study on the frequency of the transition of ulcer of the stom- ach into cancer in 1,000 cases of cancer, in 232 of which (23.2 per cent) there was a previous history of digestive disturbance; 73 cases gave a definite history of former gastric ulcer. “It is evident therefore that in the 1,000 cases, but 23 per cent present a history of any previous diges- tive disturbance whatever, and that but 7.3 per cent give a direct history of ulcer.” “If, therefore, all of the former digestive disturbances be considered as due to ulcer, the formation of gastric cancer from ulcer could not have taken place in more than 23 per cent.” Aschoff says that a large number of chronic gastric ulcers, considered callous ulcer by the surgeon, and which have been interpreted as cancer, microscopically are not ulcers degenerated into cancer but cancers in which typical ulcers have formed. The material which was submitted to MacCarty at the Mayo Clinic was frequently examined within two minutes after its removal from two hundred and sixteen resections of the stomach for ulcer, ulcer and car- cinoma, or carcinoma. This material divides itself into three groups— 58 ulcers, 125 ulcers and carcinoma, and 33 carcinoma without any good evidence of ulcer. MacCarty under head cf “Ulcer and Malignancy” says: “The question, do ulcers become malignant as one of their sequelae seems, from my material at least, to be answered in the affirmative. What percentage heal, perforate, or become malignant is impossible to determine. The close association of carcinoma with ulcer may be strik- ingly seen in the fact that 71 per cent of all our resected specimens of the stomach for carcinoma were associated with definite ulcers (Wilson DISEASES OF THE STOMACH 595 and MacCarty) and that 68 per cent of the resected ulcers of the stomach, including the duodenal ulcer, which rarely becomes malignant, were asso- ciated with carcinoma.” Finally Rippert, who is probably the leading authority on human cancer, in his great work says that he has seen three cases of positive can- cerous development in ulcer of the stomach, and pictures one of these in his work. Our own material does not justify the presentation of statistics. We have, because of the great importance of this subject from the diagnostic, prognostic and therapeutic standpoint, presented the most recent data available. For our purposes it may be concluded that on the whole, in spite of the great differences of opinion which exist with regard to the frequency of the degeneration or transition, we must admit that ulcer of the stomach is a positive factor in the production of cancer, and prognosis and treatment should be framed accordingly. In our experience we have never seen a case of duodenal cancer resulting from ulcer. 4. Cicatricial Distortion and Stenosis.—In the process of heal- ing and proliferation the two conditions which are most frequently faced are pyloric obstruction and hourglass contraction of the stomach. The first condition, pyloric stricture, we consider fully in connection with the benign stenoses of the pylorus (See Pyloric Obstruction). Without complications the prognosis, unless the patient has been ex- hausted by inability to nourish himself as the result of extreme stenosis, surgery offers an excellent prognosis. Medical treatment is of no avail in extreme cases; with moderate narrowing, life may be prolonged indefi- nitely with careful regulation of diet. The x-ray picture will prove of material assistance. The diagnosis of hourglass contraction can only be suspected; it can be positively confirmed by x-ray examination in most cases. Consecutive dilatation of the proximal part of the stomach may give rise to all of the symptoms of gastrectasia. The complication is rare. Medicine offers nothing to relieve the symptoms; most cases are not extreme and remain fairly comfortable. Without complication in extreme narrowing, the prognosis for life is good, for surgical interference also good. 5. Perigastric Adhesions.—Most adhesions resulting from ulcer of the stomach do not lead to serious complications or annoying symptoms. Brinton demonstrated their presence in 40 per cent of ulcers. Perigas- tritis is likely to accompany acute exacerbations of chronic ulcers. With each acute exacerbation adhesions or localized thickening over the ulcer may be expected. This process is at times conservative and salutary, for the local thickening may prevent perforation or limit its ravage. The adhesions which result to the liver, spleen and intestines lead to pain on movement, particularly bending and stretching. When the new 596 DISEASES OF THE DIGESTIVE APPARATUS tissue is dense and thick there may be tumor formation—at times puzzling for diagnosis. In rare cases the adhesions may lead to pyloric obstruction with symptoms of motor insufficiency. Adhesions which distort the duodenum may cause regurgitation of bile into the stomach with consecutive symp- toms. Most perigastric adhesions require little or no treatment; the deforming, constricting perigastritis demands surgical treatment which offers only reasonable chances of relief. Reformation of adhesions with extensive perigastritis is the rule. 6. Exhaustion.—Exhaustion due to causes other than the serious complications mentioned is at times the cause of death (but rarely). Long continued, uncontrolled vomiting, associated chlorosis and extreme chloranemia, excessive menstruation, irritable or diseased heart, tuber- culosis or other diseases may prove factors in causing alarming exhaustion. The blood picture often during considerable periods shows all of the evidences of grave anemia which is associated with ulcer symptoms and great exhaustion. This is the complex which exists in young girls very often. Barring accident in spite of the fact that the heart often shows marked muscular enfeeblement and there be slight albuminuria, almost all of these patients recover. It is often surprising to note the extreme exhaustion and anemia even after hemorrhages, and the final restoration of blood elements and strength. It must not be forgotten that ulcers of the stomach and duodenum are often associated with other diseases which powerfully influence prognosis (nephritis, chronic heart and lung disease, etc.) (Rossle), in which there may he extreme exhaustion. 1. Parotitis (Metastatic?).—In several of our cases we have seen parotitis during the height of the symptoms. Most of these have been found during or after hemorrhage. The swelling is painful; there is the usual rise of temperature and acceleration of the pulse. Hone have suppurated; all have recovered. 8. Tetany.—We have elsewhere in this volume called attention to the association of tetany with stomach and duodenal ulcer. It is always a serious complication and when it recurs demands surgical treatment, which offers a good chance of relief. In some cases in which the ulcer is healed but there is secondary stenosis (incomplete) and motor insuffi- ciency, tetany is prevented by repeated lavage and diet. 9. Acidosis.—There are occasional cases of peptic and duodenal ulcer in which alarming and threatening acidosis develops. Acetonuria and acetonemia are easily recognized; with acetone there is diacetic acid, and with persistent vomiting and other evidences of poisoning, charac- teristic breath, small pulse, thready and rapid, features pinched and eyes sunken, respiration is increased and death may follow. This is not the fate of all ulcers with acidosis, for in some during periods of exacerba- DISEASES OF THE STOMACH 597 tion, there is only moderate poisoning. The fact remains that cases of extreme hyperacidity and hypersecretion in which there is uncontrollable vomiting are most likely to develop acidosis. Contrary to the usually accepted theory of destruction of the liver cells and excess of ammonia in the urine, it has been suggested by Under- hill and Hand that the excess of ammonia ought not to be attributed to the degeneration of liver cells but to the direct results of starvation dependent upon uncontrolled vomiting. Dreschfeld has called attention to attacks of fainting with acetone and diacetic acid. We have had such cases in which threatening acidosis never developed. Rational treatment influences the majority of mod- erate acetonemies favorably and promptly. The deep involvement of the sensorium, rapid respiration, extreme weakness and small pulse are serious—not necessarily fatal. We have had a number of satisfactory recoveries. Important Considerations We have in private practice found ulcer of the stomach in 1.4 per cent of our cases of internal disease with a mortality of less than 2 per cent. The mortality of simple and complicated gastric ulcer with sur- gical treatment would naturally be high, as the average would be lifted by emergency operation for perforation or for any complication. Musser compiled reports from literature and various private sources; his results include a large number of operations during the pioneer days; they varied between 10 and 25.9 per cent. It is unfair to offer an opinion in the individual case based on sta- tistics which cannot possibly be considered to include parallel conditions nor equal skill or resourcefulness of the various operators. Hence sta- tistics bearing on this subject will probably never be of great value, save as they prove the possibilities in the hands of the expert and the average results of all operators. The mortality for simple ulcer after surgical operation varies from less than 2 per cent (Mayo-Moynihan) to 10 per cent and more, and it has been demonstrated that operations for duodenal ulcers present a higher average of cures than operations for gastric ulcers. Prognostic Significance of Age and Surgical Treatment Petren has demonstrated, in an investigation of 243 operated cases collected, that it appeared that younger subjects did not show as favor- able late results as did older individuals. In 33 women under 30 years who had been operated, 42 per cent had subsequent gastric disturbances. In 33 women over 50 years of age, only 24 per cent had subsequent trouble; and out of 41 men over 50, only 17 per cent had any annoying symptoms. 598 DISEASES OF THE DIGESTIVE APPARATUS It is exceedingly difficult to offer any statistics of value which hear upon the relative frequency of the complications of simple peptic or duodenal ulcer. Much must depend upon early treatment and care. The average statistics of ten years ago are of no value today, for medical dietetic and surgical treatment have all been improved and it is as unjust to the physician as it is to the surgeon to make comparisons which are not based upon conditions which exist at the present time. The mortality based on surgical treatment will always be higher than that offered by the internist, but in all fairness to the surgeon we must admit that this is so because the average surgical material even of simple uncomplicated ulcer includes only the more serious and chronic, oft- relapsing cases which have during long periods postponed treatment and operation, or the acute cases with symptoms of sufficient severity to de- mand an emergency operation. Musser’s analysis of cases from medical literature and a collective investigation of private cases (1,871 and 586 respectively) shows that in simple ulcer the death rate under surgical treatment was 20 per cent and under medical treatment 12.4 per cent (reported in 1907 from literature). The private cases showed a surgical mortality of 11.4 per cent and a medical mortality of 3.1 per cent. After my full rehearsal of the prognostic features of gastric and duodenal ulcers I feel safe in advising the clinician to consider the majority of these cases to he purely medical offering a good prognosis for life and cicatrization. There never is a time when the patient with an unhealed chronic or acute ulcer is not standing on the edge of a precipice ready to fall, never a moment when without warning his condition may not become sur- gical, though the large majority escape serious complications. Ulcers which are chronic and which prove their chronicity by repeated remissions and exacerbations with or without hemorrhage do not heal—the complica- tions which threaten life will complicate a small proportion of these but chronic invalidism is their positive fate, and as the exacerbations mul- tiply, adhesions and secondary changes (perigastritis, stricture of the pylorus, dilatation of the stomach) ivill prove increasingly annoying—at times threatening. Death resulting from ulcer during its incipient stage (acute ulcer) occurs in about 1 to 2 per cent. These figures approximately correspond with those of Russell. Duodenal ulcers rarely heal; they do not cause cancer. The question of surgical interference to prevent cancer from ulcer will need to be decided in the individual case. Gastric ulcer •may cause cancer but the incidence is not as frequent as the statistics of some clinics appear to prove; sufficiently frequent, however, to influence prognosis and treatment. The prognosis of com- plications has been favorably influenced by the growth of physiologic DISEASES OF THE STOMACH 599 and pathologic knowledge and the enormous improvement of surgical technic. In threatening complications, perforation particularly, life often de- pends on prompt diagnosis and immediate surgical treatment. Rest, diet and medical treatment are the paramount factors which the physician possesses to aid him in the cure of most cases or the control of symptoms. We must once more accent the fact that all threatening acute cases and all chronic relapsing cases, as well as life threatening complications demand the concerted action and ripe judgment of both the physician and surgeon—and this without delay. These facts accepted and acted upon, the mortality of gastric and duodenal ulcer will be enormously influenced and will be found to be surprisingly low (below 1.5 per cent). Aschoff. Patholog.

Cancer of the Stomach (Carcinoma ventriculi) General Considerations.—On. the basis of past statistics Hoffman concluded that during 1913, 30,105 would die of cancer of the stomach and liver; and his forecast was practically corroborated. The annual mortality in the United States from cancer, Hoffman places at 75,000; 500,000 in the civilized world. Cancer death rate is increasing at the rate of per cent per annum, and this holds through- out the civilized world. The average age of death from cancer is 60.4 years for males, and 58.2 years for females. The male cancer death rate in the United States at ages 25 and over has increased 29 per cent during the last decade, and the female cancer DISEASES OF THE STOMACH 601 death rate has increased 23 per cent. The cancer mortality in Japan ranges from 83 to 95 per 100,000 inhabitants; Moscow 56 to 103; St. Petersburg 78 to 98; Southern Italy 6 to 70; Northern Italy 51 to 68; in the Netherlands 75 to 105; Germany 33.5 to 35. In the United States in 1907 it was 79.6 per cent in the cities, 73.9 per cent in the country. Rosenfeld reports the interesting coincidence brought out by his figures that the mortality from cancer is unusually high in the district of Joachimsthal, the source of the radium supply. The study of “cancer- free islands” is of great interest; there are no “cancer-free islands” in countries in which cancer is prevalent. Kosenfeld accents the fact that “there are numerous cancer islands in countries which are generally free from it.” The rule may be accepted without modification that cancer of the stomach is always a fatal malady unless detected in its very incipiency before marked infiltration has resulted, before adhesions have formed, before neighboring glands have been involved, and before there are evi- dences of changes in the blood. There is no reason for considering the majority of stomach cancers to be other than primary, therefore, no valid reason for concluding that cancer of that organ, if radically treated, during its early days differs from primary cancer, elsewhere which offers a favorable prognosis only under the conditions mentioned in the preceding paragraph. There are powerful factors, however, which make the early recogni- tion of stomach cancer exceedingly difficult and usually impossible save by exploration. The stomach is a tolerant organ; it continues to perform its functions during relatively long periods in the presence of organic disease which it continues to tolerate without creating a suspicion of its presence. The intestinal and pancreatic functions compensate for the failure of full gastric digestion, while the patient, in most cases, in the presence of few symptoms of “dyspepsia” is but little disturbed by these, and usually fails to seek medical assistance; when he does, in the very early days of the disease, the diagnosis remains, as already said, difficult and uncertain. We are reminded that the consideration of these tests, together with clinical history, should make early diagnosis easy: the analysis of the stomach contents, the testing of the motor function, the x-ray examina- tion, the Solomon test (determination of the amount of nitrogen contained in a known quantity of water with which the stomach is washed out— because with cancer there should be an increased amount of serous fluid discharged—more than normal, hence an abnormally high nitrogen con- tent), the Graefe-Rohmer hemolytic test, and the Oppenheimer test. Unfortunately all of these do not accomplish the desired end. The thorough investigation of the Solomon, Graefe-Rohmer and Oppenheimer tests by Leitner prove that all of these have inherent 602 DISEASES OF THE DIGESTIVE APPARATUS sources of error which make the results uncertain and unreliable (Leit- ner). The early diagnosis of cancer by the Rontgen rays is uncertain and according to the most reliable authority (Haudek), carcinoma aris- ing from a callous ulcer, a fungus carcinoma which has invaded the normal stomach outline, a diffusely infiltrating cancer, may make it pos- sible to determine the character of a cancer with tolerable accuracy. These are all advanced conditions and have nothing in common with incipient carcinoma ventriculi; in all of these, the revelations of the x-rays are tardy and can only corroborate, when made, an unfavorable outlook because of the advanced changes. The repeated examinations of the stomach contents may make us suspicious, but they offer during the earliest stage but little upon which we can rely. Billroth in a personal communication to the author on this subject shortly before his death wrote: “It is true that free HC1 is more often absent from gastric juice in gastric cancer than' in ulcer; but this phenomenon is not sufficiently constant and may be physiological. It is not sufficiently definite to be of practical value.” Billroth added: “I consider the differential diagnosis of an ulcer of the stomach with cicatrization and beginning carcinomatous infiltration from primary can- cer as very difficult and usually impossible, ofttimes impossible when the fresh specimen is before us and cut into, only possible after many and large sections have been made and examined microscopically.” We have mentioned these facts as a preface to what follows because they demonstrate the problems which confront the clinician if he would im- prove the forecast of the disease under consideration. The patient, if he be saved, must consider his symptoms with his attendant early and the physician must learn to associate these symptoms with possible malignant disease of the stomach. Patients will never learn to present for early diagnosis until we have made clear to them, as we have to the incipient tuberculous, the facts relating to carcinoma which make prog- nosis favorable. Therefore, we repeat, early diagnosis is the only hope of the patient who has stomach cancer. Depend upon laboratory methods or any one symptom for diagnosis and your patient’s death warrant has been signed. The pyloric portion of the stomach is the seat of cancer in over 70, Mayo says 80 per cent of stomach cancers—therefore in the majority. The earliest evidences of motor insufficiency and stagnation (at the cancer age or earlier), food remnants after seven hours with pyloric resistance, and tumor, are the most dependable of all symptoms; all other data are of secondary import. In over 90 per cent of our cases there was a palpable tumor at the time of the first consultation. This fact proves that symptoms are absent or insignificant and treatment is not demanded until the process is well advanced. To the above we add the Leube rule, which should be indelibly im- pressed on every diagnostician: DISEASES OF THE STOMACH 603 “Cancer of the stomach is 'present in all probability if a questionable stomach disease has attacked a patient between 50 and 60 years of age who formerly digested all food well. If such a person becomes dyspeptic without an evident etiological factor, it may be assumed with considerable certainty that he is developing gastric cancer.” uCancer during early life is by no means exceptional, and this fact cannot be ignored in either diagnosis nor prognosis. The average per- centage of stomach carcinoma in early life is between 2.5 and 4 per cent. Osier reports in 3,257 cases of stomach cancer 2.5 per cent below the age of 30 years. Welch in 2,028 cases found 2.5 per cent below 30. Stomach cancers in early childhood are exceedingly rare. Rolleston and Hague report 17 cases collected from medical literature. One was an infant 10 days old, reported by Cullingsworth; Welch considered the growth to be congenital. Between 10 and 20 years of age cancer of the stomach is likely to be more acute than in the adult and usually runs a rapid course. After 20 until 30, reported cases show rapid progress to death. Mathieu in a series of 19 cases in young subjects, also quoted by Osier and McCrae, estimated the duration at three months. Eleven of Mathieu’s cases lived months; 6 lived 6 months and 2 one year. Latent periods are not to be expected in the cancer of early life. The scirrhus cancer is the most frequent; colloid second; encephaloid third, and always of rapid growth; epithelial fourth; and adenoid fifth. Welch in 1,885 reported that “it is probably fair to conclude that in Hew York not over 1 in 200 of the deaths occurring at all ages from all causes is due to cancer of the stomach, and that about 1 in 100 of the deaths from 20 years of age upward is due to this cause.” Our statistics show the larger number of stomach cancers in male subjects. Welch believes the liability of the sexes is the same. Heredity is certainly a factor—less frequent than has been supposed (15 to 20 per cent). It is not uncommon to find several members of a family with cancer of the stomach, a fact which is confirmed by the experience of the average busy clinician. It is an interesting fact that in most of these the symptoms appear at about corresponding ages. Secondary stomach cancer is rare, but possible. Welch’s material included 17 secondary to cancer of the breast. We have seen similar cases, and in one woman we found first uterine cancer for which she was successfully operated, later breast cancer also successfully operated, and finally stomach and liver metastases. The negro is rarely afflicted in his native country (Africa), while in the United States the proportion of deaths—as determined by Welch in an analysis of “7,518 deaths among this race in Hew York”—was about one-third less than among white persons. 604 DISEASES OF TIIE DIGESTIVE APPARATUS Prognostic Significance of Leading Symptoms Pain.—Pain usually present, is not a symptom of great prognostic value; the rule may be accepted that pain is not, as a rule, an early symp- tom, that its persistence is evidence of advanced disease. Vomiting.—Vomiting is absent from one-eighth to one-fifth of can- cers of the stomach (Lebert and Brinton). In such cases there is no consecutive constriction at either end of the stomach. When the cancer is located at the cardia, it may lead to all of the symptoms of esophageal stricture, the vomiting or regurgitation follows promptly after taking of food. Dilatation, pocketing of the esophagus, with contraction of the stomach follow after a few months of symptoms and progression. Vomit- ing is present in practically all cases in which the pylorus is the seat of disease (80 per cent). The greater the quantity vomited at one time, the more dilated will the stomach be found and the greater the obstruction. Vomiting of blood, hematemesis, is not an early symptom except in cases in which there is infiltration of the base (ulcus carcinomatosum) of an old ulcer. These cases, often run a chronic course and are often slow to develop metastases. The “coffee ground” vomitus is evidence of advanced change in the growth (degeneration and ulceration) ; usually there is marked emaciation, cachexia, anemia, and muscular enfeeblement at the same time, with a failing heart (small pulse) and evidences of distant metastases. Under these conditions life is not prolonged. Once there has been marked emaciation there is but small chance of improvement; progression is manifest in the daily loss of strength and the increase of stomach symptoms. Stomach Function.—Stomach function is always disturbed in the presence of cancer. In the latent cases the reduction may be so slight as to remain unnoticed—no symptoms or but few; the tolerant stomach is relieved at the same time by the compensatory action of the pancreas and intestines. This ability of the stomach, when the pylorus has been re- moved to regain sufficient motor ability that the duodenum may carry on digestion, is the prime factor in the prognosis of early radical treatment of pyloric cancer. Miculicz and Rosenheim found that in three months motor function was sufficiently restored after removal of the pylorus to empty the stomach of its contents in five hours and a half; the duodenum and small intestines assume the stomach’s work. Ninety per cent of our cases show a reduction of free HC1. In average cases pepsin will be pres- ent, but reduced in accordance with the destruction of the peptic glands. Lactic acid is likely to be present; it is not pathognomonic. Lactic and other organic acid with reduced HC1, the Boas-Oppler bacillus, blood and mucus are presumptive evidence of gastric cancer. The yeast fungus is present in advanced carcinoma. When bits of cancer tissue are vomited the disease is advanced, and ulceration or breakdown is progressive. When DISEASES OF THE STOMACH 605 the vomitus has a gangrenous odor, sloughing and sepsis go hand in hand. Such cases often have fever and may show marked toxic symptoms (cere- bral) as the end approaches. The condition of the bowels is of no great significance unless there is persistent diarrhea, when the effect is weakening; usually constipation is troublesome. Stomach Contents.—The diagnosis of cancer of the stomach once established the condition of the contents, whether there is absence or presence of HC1, is only of slight prognostic value. The cases in which there is subacidity (not complete absence) do sometimes run a longer course than do those with complete anacidity (absence of the HCl), par- ticularly if there be achylia gastnca, which with carcinoma is indicative of far reaching infiltrating disease and atrophy of the gastric follicles. The cases with persistence of free HC1 are usually, not always, ulcus carcino- matosum. and these are likely to be chronic with latent periods to be men- tioned later. The presence of lactic and other organic acids (butyric, acetic), with the Boas-Oppler bacillus and yeast, is usually significant of advanced carcinoma and probable motor insufficiency (stagnation). Golding Bird in 1843 demonstrated the absence of free HC1 in pyloric cancer with dilatation but his communication was ignored until von den Velden at the Kussmaul Klinik systematically investigated the subject and established its diagnostic value. Free HC1 is the remnant which is left after all affinities have been satisfied. With “the constant presence of free HCl made positive after repeated examinations and a normal peptic strength” it will rarely be necessary to consider cancer of the stomach. Riegel would not consider the diagnosis of cancer under such conditions “however strongly they (the symptoms) point to it.” The greater the infiltration the more likely are we to have reduced HCl and the worse is the prognosis—this is particularly true when at the same time there is little pepsin and no peptones. Cancer of the pylorus may be limited, always fatal when advanced and yet free HCl is usually present, “its absence is the exception” (Cahn and von Mehring). This ought not to be accepted as a rule. Free hydro- chloric acid was absent in 92.7 per cent of my cases; present, but markedly reduced, in 7.3 per cent. The Glycyltryptophan and the tryptophan tests have been fully con- sidered by Smithies who reports on 1,400 cases of diseases of the stomach examined at the Mayo clinic. From these we can draw no data which influence prognosis or make positive the early diagnosis of cancer of the stomach.* * The tests are known as the Fischer-Neubauer glycyl tryptophan test for the presence of polypeptid splitting ferments and the Weinstein tryptophan test for the presence of free amino-acids. 606 DISEASES OF THE DIGESTIVE APPARATUS Smithies found the first mentioned test present in 31 of 81 stomach cancers, the tryptophan test was positive in 7; with 35 ulcers 9 showed Fisher-Neubauer test and 3 the Weinstein; with 87 duodenal ulcers 3 and 3 respectively. Other diseases—benign pyloric stenosis hypoacid anacid- ity, gastritis, neuroses and achylia gastrica, also gall-stones, cancer of liver, appendicitis, and pernicious anemia—gave positive results. No other disease gives so many positive reactions as does cancer of the stomach but in the absence of other suggestive or classic symptoms and positive Fischer-Neubauer and Weinstein with the knowledge that other diseases with similar symptoms give the same results, we are left without any material assistance from these tests. Feurer says “We can only consider the tests (including the Salowski—colloidal nitrogen, the hemolytic bodies, the Graefe—Rohmer and the Neubauer-Fischer tests) of value when the clinical features are corroborative”, and when these are, the disease is advanced far beyond the period of incipiency or even the first stage. Blood Picture.—The blood picture is of value in giving a fair esti- mate of the ability to nourish the patient. With progressive loss of strength, weight, and increasing secondary anemia and cachexia, life is threatened. With average infiltration the cachexia will always he out of proportion to the anemia—of diagnostic as well as prognostic value. My average red count at the time of positive diagnosis has been 3,500,000 per c. mm.; hemoglobin 50 with leukocytic range between 10,000 and 15,- 000. In some cases, where there is excessive vomiting the count may tem- porarily approach a polycythemia. This is rare, however. Fever.—Persistent fever, usually F. is not infrequent; it is almost always evidence of the terminal stage of the disease. But few cases die without rise of temperature at some time during the course of the disease. When fever persists it is an evidence of absorption of toxins and it is an unfavorable symptom. Chills and fever are always suspicious of sloughing and consecutive sepsis. The behavior of the heart and circulatory organs is of value in giving an index of the patient’s resistance as well as deciding in conjunction with physical signs and subjective complaints on the probable duration of life. The Urine.—The urine offers but few data. The chlorids are re- duced; there is usually, particularly in the advanced stage, indicanuria; there may be nephritis or albuminuria. I examined the urea content in all of my cases and have learned that advancing cases, during limited periods, often show very high urea loss. The urea estimation in all suspected cases is valuable for diagnosis and prognosis. When the disease is advanced the amount of urea is diminished. Acetonuria, if slight is not, per se, of great significance, it may cause no symptoms; when it does and the symptoms of acidosis are prominent the danger is great. DISEASES OF THE STOMACH 607 Dropsy.—Most cases are either edematous before they die, or there are evidences of dropsies of the serous cavities, or both. Dropsy is always an evidence of the approaching end. With dropsy there is usually marked cachexia and anemia; most dropsical patients have died with symptoms of toxemia, more or less delirium, and final coma. Ulcerative Stomatitis and Dry, Red, Glazed, Cracked Tongue.— Ulcerative stomatitis and the dry, red, glazed, cracked tongue are among the terminal conditions. I have never seen a case fall into a period of latency or remission after the tongue shows decided change. Perforation.—I have had no death in my practice due directly to perforation of the stomach wall. In one case there was perforation into the adherent transverse colon (gastrocolic fistula) which was at first unrecognized because, as the stomach was inflated, the distension of the colon simulated dilatation of the stomach. This patient lived a number of months after the perforation. There are a number of cases of peri- tonitis on record following perforation, but this combination is rela- tively rare. Latency of Gastric Cancer In 1893 I called attention to a series of cases which justified the conclusion that latency of stomach cancer is not unusual. There may he after symptoms strongly suggestive and sufficient for tentative diagnosis, marked improvement during varying periods, gain of strength and flesh, improvement of stomach function, approximate return of normal gastric juice, favorable change in the blood picture—all sufficient to create the suspicion of faulty original diagnosis. In some cases the motor func- tion as shown by tests has increased. In these cases it may be as- sumed that stenosis does not exist to any high degree and that the intestines, and the duodenum particularly, are sufficient to nourish the patient. These cases are therefore without much constriction at the py- lorus or secondary dilatation, or there is infiltration with only moderate thickening at the pylorus. The length of the periods of latency varies, the longest period in my experience being 6 years; during the early stage there were characteristic symptoms. This was not a case of cancer upon the base of an old ulcer as was proved by the post mortem. Death followed 12 months of continuous symptoms. There are cases in which cancer remains latent, never causing subjective symptoms and is detected post mortem, death having been due either to accident or intercurrent disease. The blood picture of stomach cancer is not characteristic, but in this class of cases there may be less cachexia than is usual. As the process advances and the powers wane the cachexia is relatively greater than the anemia. The unfavorable features which show progression and presage an early ending are those of increasing stagnation, dilatation with periodic vomiting, progressive loss of flesh, increasing cachexia, and secondary 608 DISEASES OF THE DIGESTIVE APPARATUS anemia. In these cases after the long period of latency, the tumor is usually palpable. Infiltrating cancer without palpable tumor, cases in which the stomach wall is evenly invaded, may not cause stagnation. The pylorus may not be constricted; if it finally is, then there will be stagnation with moderate dilatation and progressive, often rapid emaciation. With infiltrating cancer which may be mistaken for non-malignant atrophy of the gastric follicles, there will be remnants of the previous days’ food, usually absence of IIC1; lactic acid will be present; there will be progression of the disease, never improvement of functional activity cf the stomach. Whenever the cancerous growth fails to cause stagnation, the prominent symptoms may mask the primary disease. Such patients often die with the secondary manifestations in the ascendency. In some cases death may follow with the secondary lesions of liver cancer promi- nent, but few or no stomach symptoms. Both latent and infiltrating carcinoma may present symptoms of metas- tases before local evidences or subjective symptoms of existing disease. The most frequent metastases are to the lymphatic glands (in of all cases), to the liver in an almost equal number, and to the peritoneum, omentum and intestines in approximately £ of all cases, the pancreas in -J, the pleura and lung in 1-15. We have called attention to metastasis to the nervous system from cancer of the stomach and intestines. The secondary growths may be more conspicuous in causing symptoms than the primary. There may be invasion of any part of the nervous system, peripheral, spinal, or cerebral. Welch reported 9 metastases to the brain and meninges in 1,514 cancers of the stomach. Pinatelle and Cavaillon report 2 cases of gastric cancer with secondary deposits in the cranial bones. Metastases Additional Considerations Long periods of latency or remission of symptoms alone can justify the belief during limited periods, that gastric cancer is curable. If the disease is carcinoma, relapse and death are sure to follow. The cases of so-called “self-cure of cancer ’ are usually ulcer with thickened or fibroid base—never cancer. I fully agree with Mayo when he makes the follow- ing positive statements: “In all the history of disease there is no authenticated case in which a cancer of the stomach has been cured by medical means.” Accepting this view, as absolutely true, we once more find ourselves face to face with the problem of early diagnosis and prompt surgical interference if we would save the lives of these patients. It is not within the province of this work to deal with surgical questions, but only benefit can result from the presentation of a few data taken from the DISEASES OF THE STOMACH 609 material of those in whom we may place reliance that the prognosis of the disease may be improved and cancer of the stomach may from the very beginning of observation of the individual case demand the attention of the diagnostician and the surgeon. Mayo reports: “Cancer of the stomach, when still localized, gives operative results as good as those after operation for cancer in any other part of the body; it has no higher grade of malig- nancy nor is the operation for its removal more difficult than operation for the cure of cancer in other organs of the gastro-intestinal tract.” It is obviously unfair to compare results today with those of even five or ten years ago—so great has been the improvement of technic—and so much better educated is the public that results are growing more and more favorable; the mortality is steadily diminishing. I was present at the Billroth clinic during the early days of the work in which he was the pioneer, and I have recently had opportunity to compare it with modern surgical methods in this country and abroad. The revelations are encouraging and prove the courage of the master who paved the way as well as the fact that the mortality of all plastic operations on the stomach depends not only on the early diagnosis but upon the cool judgment and superior skill of the surgeon. In no field of medicine does prognosis depend more upon the experience—the most valuable asset of the oper- ator. Mayo reports a mortality of 7 per cent in his last 100 cases; in the last 50 of these, 4 per cent. He modestly adds: “nor are these figures exceptional.” In this latter conclusion we differ from him; he under- estimates the value of his experience in the cases preceding his last 50. Xo patient can be considered cured who has not remained well five years. “Of 307 resections of the stomach for known carcinoma 150 of the patients were operated more than three years ago; 20 died from the results of the operation, and we were unable to trace 40. This gives 90 patients who recovered from the operation and whose present condition we have been able to trace. Of this number 33 or 36.6 per cent are alive. Of the 93 patients operated more than five years ago, 15 died and 20 have not been heard from as to their present condition. Of the remaining 58, 13, or 22 per cent, are known to be alive and well over five years. Every death occurring within the five year period has been classed as a death from return of the cancer without regard to the actual cause; this is an injustice to the statistics, since the normal death rate for five years of people the age of these patients is at least 8 per cent.” These results prove that “in the operated cases 90 per cent chance of recovery from the operation exists, a 36 per cent chance of 3 years of life, and 25 per cent of 5 years.” Faroy reports as follows on his surgical experiences with cancer of the stomach: Exploratory laparotomy was done on 8 cases, 6 of which died soon after opera- tion (3, 19, 23 and 30 days) from postoperative complications; 2 survived, 1 six 610 DISEASES OF THE DIGESTIVE APPARATUS months, the other 1 year, in spite of the presence of ganglia, adhesions and infil- tration of the gastric wall and gastrohepatic ligament. Gastro-enterostomy—39 cases; 8 survived only from a few hours to several days. 11 “ up to 6 months (2, 3, 4 and 6 months). 9 “ more than 6 months (7, 9, 10, 11 and 12 months). 9 “ from 1 to 2 years. 3 “ for 1 year 3 months. 2 “ “ 1 " “ 5 “ 2 “ “ 1 “ 10 “ 1 “ “ 1 “ 11 1 “ “2 years. 1 “ more than 2 years (2 years 6 months). 1 u u iC 3 iC 3 u 4 il Of these patients 9 had pyloric or prepyloric cancer, and survived as follows: Several hours 2 3, 6 and 7 months 3 1 year, 1 month 1 1 year, 10 months 1 1 year, 11 months 1 3 years, 4 months 1 Fifty per cent did not live one year; 45 per cent lived more than one year. Of 30 other cases of pyloric and prepyloric cancer and cancer of the lesser curva- ture, 77 per cent did not live one year, 23 per cent more than one year. In 12 cases the neoplasm was extensive, had infiltrated the glands or contracted adhesions with the liver and pancreas: 2 died after several hours. 2 u “ “ days. 5 “ before 1 year (7, 8, 10 and 12 months). 2 “ “2 years (13 and 23 months). 1 lived 3 years and 4 months in spite of pancreatic adhesions. 25 per cent did not live 1 year; 30 per cent not more than 1 year. Pylorectomy.—Simple pylorectomy (Billroth’s method No. 1) shows different figures from gastro-enterostomy. Of 10 patients, 5 died soon after operation from complications: 3, 7, 15 and 30 days. 5 survived: 1 year 6 months. 1 “ 9 “ 2 “ 2 “ 3 “4 “ 4 “ 6 « One patient in whom a total gastrectomy was done survived 3 years in spite of extensive lesions. Billroth’s method No. 2 gave similar results. DISEASES OF THE STOMACH 611 Of 6 patients, 2 died 10 and 15 days after. 4 survived: 10 months. 1 year 1 month. 1 “ 4J months. 1 “ 10 “ If we combine the figures of these two groups we find 7 deaths out of 16—a postoperative mortality of 45 per cent. The mortality in the cases operated accord- ing to Billroth’s method No. 1 was 50 per cent, that of method No. 2, 33 per cent. Temoin reports that the following results were obtained in 11 years, from 1898 to 1909, on 168 tumors of the pyloric region. Of this number, 91 were operated before 1908, and 77 in 1908 and 1909. Of the first 91 cases, 38 are dead, 24 dying within 5 days after operation and 14 within 15 days. Of those operated in 1908, 44 cases, 4 died within the first 5 days and 3 within 15 days. Of those operated in 1909, 33 cases, 2 died within the first 5 days and 3 within 15 days. The figures show a uniform decrease in the immediate results of the operation, due to the ability of the operator and improved technic. Of the 119 that survived operation, 47 are still living and in good health: 1 operated in 1898 13 years. 1 “ “ 1899 12 ‘ “ 1 “ “ 1901 10 “ 4 “ “ 1902 9 “ 5 “ “ 1904 7 “ 3 “ “ 1905 6 “ 4 “ “ 1906 5 “ 5 “ “ 1907 4 “ 8 “ “ 1908 3 “ 15 “ “ 1909 2 “ “Setting aside the 15 survivals since 1909, that is 2 years ago, a sufficient length of time for recurrence, we still have 32 without any symptoms of relapse.” The oldest living case was one in which the tumor had so far advanced that exploratory7 laparotomy was done, and in spite of the objections of the attending physician Temoin removed the growth. This was 13 years ago and the man is living, works and eats everything. Examination showed the growth to be a car- cinoma. The greatest number of the cases operated were between 45 and 55 years; the youngest, 22 years, died 2 years later from metastases in the liver; the eldest, 71 years, died 27 months later from generalized cancer of the peritoneum. Federman offers the conclusions of the Germans; they are: Resection is justified so long as the growth has not extended beyond the stomach or has not invaded the liver or pancreas. The size or seat of the limited growth are no contraindications. The author contends that the pessimistic views entertained are not justified, for from 20 to 30 per cent of operated cases are permanently cured. Complications Among the complications besides metastases are thrombotic 'processes, not due to the secondary deposits in the liver, i. e., catarrhal jaun- 612 DISEASES OF THE DIGESTIVE APPARATUS dice, gall-stones, pancreatic invasion by continuity, pressure on tlie bile duct, pancreatic duct, the portal lymphatic glands and the liver itself (Welch). Chronic gastritis, non-malignant peritonitis, enteritis, colitis, nephritis, pericarditis and after perforation pyopneumo-thorax, abscess or gangrene of the lung. Hypostatic congestion of the lung was found at post mortem in a num- ber of the more chronic cases. Tuberculosis may accompany cancer; it is not a frequent complication. Healed tubercle nodules are not at all infrequent. Purpuric and embolic conditions are always terminal manifestations of malnutrition. Barring cases with latent periods, the average duration of life was fourteen months. Schweppe reports an acute case of twenty weeks’ dura- tion. Encephaloid cancer has run its course in less than three months. Boas reports five weeks’ duration of an acute, probably encaphaloid growth. Much depends on the extent, rapidity and location of the growth as well as the dissemination of the metastases, the individuality and the re- sistance of the patient as well as the complications. Hemorrhages are rarely sufficiently profuse to shorten life though they have a depressing effect on the patient. The mortality of cancer of the stomach will be reduced and life prolonged when we have educated the layman and the profession to appreciate that in all doubtful cases which justify the sus- picion, exploratory incision is imperative and radical surgical intervention is demanded when the infiltration is found to be limited, is without distant metastases or more than local glandular invasion. It must be remembered that a small and symptomless nodule in the stomach may cause metastasis to a distant organ. “Cancer of the stomach is the most frequent and the most hopeful form of cancer in the human body. Early operation affords the victim the only chance of cure” (Mayo). References Bird (Golding). Contributions to the Chemical Pathology of Some Forms of Morbid Digestion. 1843. Boas.

Hematemesis—Gastrorrhagia Hematemesis (or vomiting of blood) and gastrorrhagia (or hemorrhage from the stomach) are not absolutely synonymous. A patient with gas- trorrhagia may have hematemesis, or vomit blood, -while the patient with hematemesis may vomit blood which does not come directly from the stomach. Extragastric Bleeding.—Extragastric bleeding which leads to hema- temesis is, as are all bleedings, purely symptomatic and may be due to a variety of causes. It not infrequently happens that the tuberculous patient with a profuse bronchial hemorrhage swallows considerable blood and finally vomits it; the same is true of profuse epistaxis. I mention hemorrhage from esophageal varix with Bantis disease, also with other esophageal lesions (ulceration, etc.). Decubitus esophageal ulcer may lead to hematemesis also specific, tuberculous and esophageal peptic idcer, low down. With chronic valvular lesions and portal de- struction, varices or profound engorgement of the esophagus may cause extragastric bleeding. 614 DISEASES OF THE DIGESTIVE APPARATUS Aneurismal ulceration, usually aortic, with final rupture into the esophagus is a cause of death. The bleeding may at first be slight, but suddenly it becomes profuse and is promptly fatal. Tumors within the thorax or abdomen may by pressure cause hemorrhage. Intragastric Hemorrhage.—With splenomegaly due either to leuko- cytic leukemia, splenic anemia, pernicious malaria, pernicious anemia, or other grave diseases there may be gastrorrhagia; it is always threaten- ing and may either deplete the patient if profuse and cause death or it may materially shorten life. Banti’s disease without esophageal varices may cause profuse gastric hemorrhage due to profound engorgement of the vessels of the stomach, gastric varix or hemorrhagic diathesis (purpura). Cirrhosis of the liver is one of the most frequent causes of hematemesis. Amyloid degeneration of the mucosa, acute yellow atrophy of the liver and surgical lesions are also included as causes of hematemesis. Chronic hyperemia of the gastric mucosa from whatever cause, circula- tory disturbances as a rule, including chronic valvular and myocardial lesions, may cause gastric bleeding. Hemorrhage from ulcer and cancer of the stomach is separately con- sidered. The former may threaten, occasionally does destroy life; the latter is rarely sufficiently profuse to interfere materially with the course of the disease; it is, however, an expression of disorganization and ad- vanced disease (See Cancer and llcer of the Stomach). With the infections, gastric hemorrhage is experienced. These in- clude smallpox, measles, typhus and typhoid fever, relapsing fever, acute yellow atrophy, embolic infarct with sepsis—indeed, any infection with purpuric or embolic processes or profound and disorganizing constitu- tional disturbances may be responsible for hematemesis. Various poisons, metallic and vegetable, food poisoning (phosphorus, etc.) may lead to moderate, at times, profuse stomach bleeding. Hemophilia, the severer purpuras, at times chronic purpura, are fac- tors, the recognition of which for rational treatment is all important. Following abdominal operations, more frequently than others, particu- larly if the omentum is injured, gastric hemorrhage may follow. With such complication there is usually peritonitis, and the prognosis is grave. I have seen gastrorrhagia with intestinal obstruction. Hysterical hematemesis. is not frequent ; it may occur but is never serious. Simulation in unexplainable cases should be considered; its de- tection has often proved exceedingly difficult. Hematemesis or gastrorrhagia, always symptomatic, the influence can only be considered with the underlying cause in the individual case. The intragastric hemorrhages rarely lead to death directly; they are not usu- ally profuse unless a large vessel has been eroded. The extragastric con- ditions are more likely to cause profuse and fatal hemorrhages (aneurismal DISEASES OF THE STOMACH 615 rupture, traumatism, large varices, etc.). Epilepsy may occasionally cause transitory insignificant gastrorrbagia. Hemorrhage from the stomach with the infections is usually an evi- dence of malignancy of the infection, and is of grave import. Septic con- ditions with multiple hemorrhages including gastrorrhagia are generally fatal. Occasionally there is oozing from the gastric mucosa without known cause; this condition occurs in girls near puberty, without pain or other subjective symptoms. The condition is not often serious though it may, if persistent, lead to secondary anemia. It is known as gastrostaxis. Purpuric or hemorrhagic conditions in the newborn with hemorrhages from mucous membranes is almost always fatal. We have seen petechiae and cord infection with these cases. 9. Gastric Neuroses (Nervous Dyspepsia, Dyspepsia nervosa (Leube) General Consideration.—The consideration of dyspepsia is now lim- ited entirely to those forms of (1) sensory, (2) motor, and (3) secretory anomalies in which no anatomical change in the stomach can be diagnosti- cated or detected post mortem. All of the neuroses are characterized by poor and deranged digestion, in which the leading symptoms and general character of the disease point to the ungeared nervous system as the seat of the trouble. I consider with neurasthenia and hysteria many of the features of nervous dyspepsia (See separate chapters on Neuras- thenia and Hysteria), and must here again accent the facts that in all there is an unstable nervous system, a strong neuropathic habit; the ego is usually in the ascendency, and the patient is so self-centered that he is unable without powerful assistance to divorce himself from himself. He is eager to will but he cannot ; his symptoms are almost continually before his mental vision, and with all forms of the disease the importance of each feature is enormously exaggerated. There is no other organ of the body which is so often the seat of symptoms of a functional character as the stomach. With all of the neuroses there may be psychoses which include manic- depressive types, hypochondriasis or other anomalies. The 'phobias (fears) or imperative conceptions (obsessions) are often in the foreground and there is a strong tendency on the part of the patient to become more and more inefficient with the severe complex. There are but few patients who suffer from nervous dyspepsia who are not neurasthenic. In some cases there is organic disease with which dyspepsia is associated. Base- dow’s disease, anemia, malaria, uterine and ovarian anomalies in women, genito-urinarv disturbances in man, suprarenal disease and spinal lesions 616 DISEASES OF THE DIGESTIVE APPAKATUS are often burdened with nervous dyspepsia. Ocular anomalies unques- tionably prove provoking factors. Often the graver disease is forgotten in the presence of symptoms referable to the stomach. 1. Sensory Dyspepsia—Hyperesthesia The leading features of the sensory neuroses are subjective. With nor- mal, perverted or lost appetite, at times a craving for unusual foods, the marked general hyper esthetic condition of the patient stands out in bold relief. Often the fear of eating, causes loss of flesh and strength. The gastric mucosa revolts as soon as food enters in some cases. The resulting pain is described as unbearable, usually burning, boring, lancinating, or there may be complaint when the stomach is empty. These patients react peculiarly to medicines and foods. At times they show great tolerance for indigestible foods, while at the same time they complain of the acute pain which follows the simplest diet. Gastralgia, so called “neuralgia of the stomach” in my experience is rarely of functional character. I do not agree with Cohnheim that the neuroses of the stomach are not associated with pain or “neuralgia,” but 1 hold that gastralgia is so rarely of functional origin that the diagnosis should not be accepted until all of the features of the case have been thor- oughly considered. The diagnosis should be made with a “loop hole” attached, through which the diagnostician will usually be forced to escape. Recurring gastralgia should always create the suspicion of gall-stones, tabes dorsalis, ulcer of the stomach or duodenum, chronic appendicitis, bone or other pressure (spinal or aneurismal). The mental condition of the dypeptic with this form of the disease is out of all proportion to the importance of his neurosis. As in all other forms of nervous dyspepsia the majority of patients are women. In some of these cases hyperacidity has been demonstrated; in the majority of cases the examination of the stomach contents offers nothing. Psychic influences, distant irritation, eye strain, a general condition below par, sexual anomalies, long continued worry, lack of occupation or overwork, occupation which is not suited to the individual, are all factors which make it impossible, unless relieved, to throw off the load which overwhelms the patient. The outlook in the cases which can be removed to the needed environment, with the relief of the neurasthenic and irritating factors, the added strong personality and overpowering suggestion of the attendant who is not wedded to polypharmacy, but who takes advantage of rational and natural methods of treating these unfortunates, is rela- tively good. These factors are important and influence the forecast of all types of gastric neuroses. DISEASES OF THE STOMACH 617 2. Motor Gastric Neuroses Motor disturbances may be due to (a) hyper motility or (b) hypomo- tility. (a) Hypermotility (Supermotility—Hyperkinesis). The prompt and premature expulsion of the food from the stomach may cause no subjec- tive symptoms, may be associated with the neurasthenic accompaniment, and can only be recognized by the use of the stomach tube or x-ray. The peristaltic unrest of Kussmaul is due to the contraction and re- laxation of the stomach musculature following the taking of food. In these cases there may be hypersecretion and hyperacidity. The attending nervous symptoms are prominent; vomiting is not infrequent; migraine is at times annoying; belching of gas, splashing noises, abnormal rapid emptying of the stomach, at times pylorospasm, all are without pain. In all of these cases the suspicion of organic disease should not be sur- rendered until there has been a thorough and satisfactory differentiation. Stockton and others have called attention to the possibility of pyloric and cardiac spasm in the same patient. Pyloric spasm long continued, as well as cardiospasms may lead to serious malnutrition. With hypermotility, the loud and annoying belching of gas (aero- phagia) is often uncontrollable during days at a time. In most of these, positively without organic fundament, the noisy and active belching ceases during conversation or distraction. We have seen a number of cases in which the symptom yielded to hypnotic suggestion; in occasional cases a sudden shock or intercurrent illness had a salutary effect. The expelled air has been aspirated or swallowed. Nervous Vomiting.—ITypermotility may cause so called "nervous vomiting.” In most of these cases there is a powerful hysterical or neurasthenic element which is materially aggravated by the persistent emesis. Between the separate emeses there may be peristaltic unrest or almost continuous belching of gas. The element of suggestion is prom- inent. The stomach, as shown by x-rays, is often filled with gas; the stomach content is found normal—occasionally there may be hyperacidity. There is never in uncomplicated cases the presence of organic acids. Rumination—Merycismus.—Rumination in the human being is ex- ceedingly rare. In my practice it occurred only twice. In both instances the patients were neurasthenic during long periods with ultimate perma- nent psychasthenia. Cases in the hysterical and insane, epileptic and idiotic, are occasionally recorded. When it becomes a habit, as it does very rarely, it is exceedingly rebellious to suggestion and is probably a stigma of degeneracy. (b) Hypomotility.—With atony of the stomach wall (musculature) the organ does not empty itself normally; there is stagnation, with final dilatation, and in some cases tetany (See Tetany). These patients are 618 DISEASES OF THE DIGESTIVE APPARATUS highly neurotic; their splashing stomachs and eructations are to them enormously significant; they develop all manner of nervous symptoms; are exceedingly unhappy and often suffer from insomnia, and as most patients with gastric neuroses, they are subject to the cardiac neuroses, jjalpitation, precordial distress and abnormal fullness. Insufficiency of the Pylorus.—In some of these cases the pylorus is insufficient—a condition which is not usually recognized. When gastric atony persists unrelieved, the general condition suffers and there is always justification for the belief that it is dependent upon an organic fundament. 3. Secretory Anomalies—Reichmann’s Disease Hypersecretion and hyperacidity may be of functional character, lleichmann first called attention to this combination which is now recog- nized by the use of the tube and examination of the stomach contents. The presence of abundant hyperacid gastric juice in the stomach, when it should be empty, is characteristic. Long continued Reichmanns dis- ease leads to motor insufficiency, in some to complete gastric atony. Gas- tralgia is a prominent symptom after great excitement or emotion. In all of these cases organic disease of the nervous system, ulcer, or other anomalies should be considered and strongly suspected. Hyperacidity (Ilyperchlorhydria).—Hyperacidity may be diagnosti- cated when the total acidity of the stomach contents is continuously above 60. Hot all who have a total acidity of 60 or slightly above show symp- toms, but with neurasthenic symptoms and stomach distress such figures do justify the diagnosis. I am always suspicious in the absence of organic stomach disease and hyperchlorhydria of gall-stones or cholecystitis, and such suspicions have often been confirmed by the subsequent history. The presence of hyperacidity continuously not dependent upon organic disease, besides a train of nervous manifestations which are common to all the gastric neuroses, is likely to cause sensory disturbances, pain, gas- tralgia and (as the condition is found in young girls at puberty) often there is marked chlorosis. Epigastric pressure, pyrosis, eructation of some fluid and vertigo are the leading symptoms besides the marked neurasthenic features. Anacidity or Reduced Total Acidity (Hypochlorhydria).—Anacidity is characterized by the abnormal lowering of free ITC1 in the stomach contents. This condition is exceedingly rare in functional disease. There is an achylia gastrica nervosa. Riegel says: “It cannot be denied that occasionally achylia gastrica may be merely a perversion of function.” Long continued achylia or hypoacidity unless recognized and compen- sated by diet and treatment leads to loss of weight and strength. In some cases which have been originally considered functional, the advent of pernicious anemia has cleared the horizon. DISEASES OF THE INTESTINES 619 In presenting the leading clinical features of the various gastric neu- roses the psychic element has remained prominently in the foreground. Dreyfus has, after a thorough consideration of his material concluded that practically all forms of nervous dyspepsia depend upon psychic changes, and that the stomach symptoms are of “secondary nature.” Pawlow’s observations prove conclusively the close relationshop of the psychic and nervous element with gastric function. What is said in connection Avith the prognosis of neurasthenia and hysteria is equally applicable in offer- ing the forecast of all gastric neuroses. The prognosis of most of these functional anomalies is good A\Then \ve have gained an insight into the prime factor which has caused and is continuing the symptom complex. This means the thorough analysis of each case, the differentiation Avhich when complete Avill materially reduce the number of these cases, and the regulation of the lives of these patients that gladness may displace the gloom which surrounds them. Besides the strong personality of the at- tendant to lead the patient, the healthy occupation of the mind will do more than anything else to bring relief and cure. Uncomplicated gastric neuroses do not lead to death. Recurrence in all forms is the rule. References Cohnheim. Verdauung u. Erndhrung. Berlin, 1908. Dreyfus (L. Georges). Ueber Nerv. Dyspepsie.

Acute Enteritis—Acute Diarrhea (a) Acute Catarrhal Enteritis Acute catarrhal enteritis—catarrh of the bowels—is one of the most frequent of all acute diseases; it is most frequent in young subjects, oftener during the first two years of life. The disease may be either 'primary or secondary. 620 DISEASES OF THE DIGESTIVE APPARATUS When acute diarrhea is primary, it is due to some error of diet, pol- luted food—ptomain poisoning—impure drinking water, epidemic condi- tions, excessive heat, with at the same time the eating of spoiled or tainted food (milk usually) toxic agents, drugs, such as arsenic, phosphorus, cor- rosive sublimate, purgatives, mental emotion, particularly fright. The secondary causes are the infections, heart diseases in which there is acute congestion of the mucosa, disease of the lung, acute or chronic congestion or obstruction in the liver, trichinosis, intestinal parasites, dis- eases of adjacent organs, extensive surface burns, nephritis, malaria, and the various cachexias. Acute duodenitis, or catarrhal inflammation which limits itself to the duodenum, which may or may not be associated with gastritis usually causes jaundice (See Catarrhal Jaundice). The latter condition is also known as gastro-duodenitis. Diarrhea is not necessarily an attendant of all catarrhal enteritides. It may be absent with duodenitis or inflammation of limited portions of the small intestine; such conditions may cause constipation. The more severe forms may involve not only the lower half of the small intestine but include the large intestines and provoke painful and weakening diar- rhea with tenesmus and heart weakness. Most of these recover after from ten to twelve days. The simple uncomplicated primary form of the disease without jaun- dice is easily controlled, and without more than a few days of weakness after the control of the diarrhea leads to full recovery without sequel. In some cases the recovery may be protracted, particularly when the cause is not at once evident or the intestinal tract has not been freed. When the mesenteric glands are involved, recovery is slow. If there are catar- rhal ulcers there may be a subacute course, but such cases are exceptional. Only rarely in average treated cases does chronic enteritis follow. Idiosyncrasies cause some to develop diarrhea (acute enteritis) when certain foods are taken which have no influence on normal individuals. These cases are easily controlled by diet. Food poisoning is elsewhere considered in this work. Enteritis due to ptomain poisoning is often severe and weakening, and when the patient is overwhelmed may prove very serious. Naturally the prognosis depends on the quantity and viru- lence of the poison, the prompt relief by vomiting early or late, and the ejection of the poison before it has been absorbed. The more unfavorable cases are those in which symptoms are postponed from twenty-four to forty-eight hours after the taking of the poison (See Food-poisoning). The prognosis of the secondary enteritides depends entirely upon the ability to influence the underlying causes; if these are remediable, as in malaria, some forms of acute nephritis, circulatory faults, intestinal para- sites, relief is possible. DISEASES OF THE INTESTINES 621 (6) Croupous Enteritis—Diphtheritic Enteritis Diphtheria may cause croupous enteritis with characteristic diph- theritic sloughs and ulcerations, and in rare cases perforation may result. The ulcerations are most frequent in the large intestine. Croupous enteritis may follow or he associated with mercury poison- ing, profound uremia, chronic nephritis, and dysentery, and may develop upon specific tuberculous or septic idcers (Mattlies). Riedel has reported diphtheritic necroses in the jejunum and ileum after laparotomy in weakened individuals. These conditions are all asso- ciated with weakening and uncontrollable diarrhea besides tenesmus and tormina. When croupous ulcerations of the intestines complicate the in- fections (pneumonia, pyemia, typhoid, smallpox and sepsis) chronic nephritis, cirrhosis of the liver, cancer or the other primary infections mentioned in the preceding paragraph, enteritis may be only superficial, without serious moment; on the other hand, it may prove to be among the terminal symptoms. (c) Phlegmonous Enteritis Phlegmonous enteritis with ulceration is not frequent. It may be associated with streptococcus infection {erysipelas), surgical lesions of the intestines, such as intussusception, volvulus, strangulated hernia, trauma- tism, or any of the mechanical obstructions. Unless the primary source of infection is relieved death will surely follow. These cases present a dark outlook. (d) Ulcerative Enteritis Ulcerative enteritis is usually secondary to the infections, including syphilis, tuberculosis, typhoid fever, dysentery, splenic fever; to the con- stitutional diseases including leukemia, purpura, amyloid disease, arterio- sclerotic changes, and infarct; also to neoplasms and conditions which originate outside the intestines, which by continuity lead to ulceration and perforation; decubitus ulceration is occasional. Acute and chronic catarrhal follicular ulcers may form after acute or subacute uncomplicated catarrhal enteritis has existed for some time; this is more likely to happen in children than adults and may prove rebellious to treatment, though the majority heal, leaving recognizable cicatrices. Ulcers may exist in adults during long periods without causing symptoms. Multiple ulcers of the intestine due to enteritis or infection may in the process of repair and final cicatrization lead to single or multiple constric- tion of the intestine, usually incomplete, but sufficient to cause symptoms of partial obstruction and chronic invalidism. The differentiation of this form of ulceration and tuberculosis is often exceedingly difficult. I have in such cases found the patient incapacitated during many years with 622 DISEASES OF THE DIGESTIVE APPARATUS almost continuous symptoms. In one such case following typhoid fever, an exploratory laparotomy disclosed multiple constrictions with collapse of intestines below the first narrowing in the jejunum and marked pocket- ing above. There were eight separate constrictions. This patient lived unrelieved during four years after the exploration, and died of asthenia. When the ulcerations are in the large intestine (rectum, sigmoid, etc.) of specific catarrhal or dysenteric origin, they are amenable to treatment and many make very satisfactory recoveries (See Syphilis, Dysentery, also Actinomycosis). (e) Mucous Colitis—Membranous Enteritis The prognosis of mucous colitis depends entirely upon its cause- All cases may he divided according to their etiology into: (I) Nervous or hysterical colitis (II) Infectious mucous colitis (III) Infantile mucous colitis (IV) Secondary mucous colitis. (I) Nervous or Hysterical Colitis.—I have elsewhere considered mucous colitis of hysterical or nervous origin (See Hysteria, Neuras- thenia). The condition is most frequent in women but is not infrequent in men. It is usually one of many symptoms which are evanescent, and its importance is almost always enormously exaggerated by the patient. The passage of mucous casts always has a depressing and discomforting effect on the patient, though in truth the strength or resistance of the 'patient is not disturbed by it. The disease is chronic; it does not as a rule yield to medical treatment but is materially influenced by psychic impressions, rest and changed environment; it may disappear suddenly and permanently without known cause, or relapses may be frequent. In some cases there is associated and weakening pain. We have never known of serious complications or death from hysterical or nervous mem- branous enteritis—a fact which it is necessary to suggest repeatedly to these patients; once indelibly impressed, the result is wholesome. (II) Infectious Mucous Colitis.—In children with intestinal infec- tion, casts or membranes occasionally form in severe summer diarrheas, vdiich are weakening and threatening. This complication is not fre- quent. In some of these cases the Shiga organism is present. With croupous enteritis in adults, without diphtheria bacilli, casts may form; unless the constitutional symptoms are severe or the enteritis deep with ulceration the prognosis is good. With acute infectious enteritis mucous casts may form, and are found in the stools. The prognosis in these cases is good. Catarrhal and infectious enteritis in hysterical subjects may be complicated by membrane formation, without materially influencing the progress of the acute inflammation. DISEASES OF THE INTESTINES 623 (III) Infantile Mucous Colitis.—The infectious infantile colitis, at times enterocolitis, has been mentioned in the previous paragraph; it may complicate cholera infantum or it may be due to faulty feeding and per- sisting intestinal catarrh and indigestion. In young children, colic and membrane formation may occur without known cause, though as a rule there are evidences in fever, rapid pulse, and constitutional symptoms of acute infection. The association of membranous colitis with the diarrheal diseases of childhood, in weakened rachitic and underfed children may prove serious. Most of my cases have made full recoveries, and a similar experience in over 95 per cent of all uncomplicated cases may be presaged. (IV) Secondary Mucous Colitis.—In grave organic diseases such as the deep ulceration of carcinoma, tuberculosis, syphilis or decubitus ulcers, membranes may form, are cast off in the stools with pain—at times tenes- mus—characteristic of the primary disease. The prognosis of the under- lying condition is almost always unfavorable, the addition of membranous enteritis is not of grave import. (/) Cholera morbus—Cholera nostras During the summer months sudden, acute, severe abdominal colic associated with diarrhea and vomiting, some fever, acceleration of the pulse dependent upon the eating of unripe fruits, bob veal or other errors of diet is frequent, but in the previously healthy is promptly relieved by simple means, often without medical treatment and without sequelae. In the very weak and sick, severe cholera morbus may, during collapse cause ominous heart weakness, but death very rarely. In previously nor- mal adults I have never known of a death. From twenty-four to sixty hours finds the patient fully restored, barring a slight remnant of weak- ness. I do not classify the infections due to the Gaertner bacillus (bacillus enteritides) as cholera nostras (See Food Poisoning) neither can we in this country accept the statistics of Eumpf (quoted by Matthes) that 10 per cent of cholera morbus patients die in collapse. If we include the food poisonings above mentioned, we might possibly approach that mortal- ity. In all doubtful cases the diagnosis will require the differentiation of Asiatic cholera (during epidemics), acute poisoning (arsenic, phosphorus, strophanthus, etc.), intestinal obstruction, gall-stones, appendicitis, per- forative peritonitis from stomach more likely duodenal ulcer, and nephritis with uremia. 2. Chronic Enteritis—Chronic Diarrhea Neglected or severe acute catarrhal euteritis may occasionally cause chronic changes in the intestinal mucosa and mesenteric glands. The 624 DISEASES OF THE DIGESTIVE APPARATUS changes may he atrophic, or there may be cystic degeneration of the intes- tinal follicles as described by Aschoff (colitis cystica). Chronic hyper- emia of the intestinal mucosa, dependent upon circulatory or respiratory disease, chronic nephritis (uremia) or constitutional disturbances, may cause chronic diarrhea. In children, chronic diarrhea with wasting, may he associated with tabes mesenterica (tuberculosis of the • mesenteric, glands), or in earliest life to what was formerly supposed to be an atrophy of the intestinal glands, but which has been found to present no struc- tural changes (Aschoff, Huebner, Schelbe and others) and is now char- acterized as enteropathia dyspepiica chronica. In the foregoing condi- tions the prognosis depends entirely upon the ability to nourish the pa- tient and compensate by proper diet for the loss of normal intestinal digestion. The classification of the chronic diarrheas of the adult is, thanks to the thorough study by modern methods of the stool and the association of symptoms with microscopic finds made possible, and the prognosis there- fore rests on a solid foundation (Schmidt and Strassburger). Intestinal dyspepsia, dependent upon fermentation, in which there are symptoms of catarrhal enteritis, persists until the fault (usu- ally faulty starch digestion) is corrected by diet and other treatment. The diagnosis and prognosis of these cases may be cleared by the exami- nation of the stools which are light yellow, contain gas bubbles, are mushy, have a sour odor, and give an acid reaction. Macroscopically there are abundant remnants of undigested potato ; microscopically after staining with iodin the starch cells are in the ascendency undisturbed, surrounded by microorganisms. Schmidt and Strassburger found fermentation of the stools in the incubator. These patients digest albumin and fat well. Un- less the condition has been present during a long time, with a suitable diet, these patients may be freed of their intestinal indigestion and chronic diarrhea. The second variety of chronic diarrhea which Schmidt classifies is the gastrogenic diarrhea. In these cases it may be assumed that stomach digestion is at fault. The stools on a meat diet show by the presence of the meat and connective tissues, shreds particularly, that gastric function is impaired. With these diarrheas, anacidity, atrophy of the gastric folli- cles or functional indigestion may be paramount (achylia). The entire failure of stomach digestion in these cases to supply the intestine with its normal stimulant is largely responsible for the symptoms. In some of these cases the hypermobility of the stomach is a factor, for not all pa- tients with achylia have diarrhea. These gastrogenic diarrheas may be dependent upon a variety of causes and may include at the same time intestinal anomalies. Matthes suggests that in the absence of a single fault in the stomach which accounts for all cases, it might be wise to characterize them as chronic gastro-intestinal dyspepsia. DISEASES OF THE INTESTINES 625 Chronic diarrhea may he of nervous origin and it is not uncommon in such cases to find alternation of constipation and loose bowels. Schmidt relegates a few of these to faulty pancreatic function, functional pancreas- achylia. Most of the nervous diarrheas are largely dependent upon psychic influences, are not easily influenced by diet or medicine, and are favorably affected by travel, environment and agreeable occupation. I mentioned the prognostic significance of chronic or persistent diar- rhea with exophthalmic goiter and Addison’s disease (See Diseases of the Ductless Glands). With both, weakening diarrhea contraindicates sur- gical interference and influences the case unfavorably. Often the symp- tom improves with the other manifestations, and gain of flesh is phenom- enal. There are individuals, usually of nervous organization, who are unable without resulting diarrhea to take certain foods, milk particularly. Such idiosyncrasy does not make wholesome diet impossible, and with compensation for the loss of one or two articles of food, weight is improved and enteric symptoms are relieved. Chronic enteritis may result from previous typhoid infection, from dys- entery, paratyphoid infections, chronic malaria, and any disease which causes atrophic or productive changes in the intestines. Such cases are favorably influenced by diet; death rarely results as the direct effect of the enteritis. There are veterans of the Civil War still living with chronic diar- rhea which resulted from acute infections of the small and large intes- tines during service. In these chronic cases there is always danger of the opium habit; among some of the veterans above mentioned the “black drop” is still taken. Habitues of opium are often the victims of secondary diarrhea, and paresis of the intestinal musculature may cause symptoms of obstruction•. Chronic ulceration of the intestines, from whatever cause, may continue diarrhea. Secondary Chronic Diarrhea Chronic nephritis, uremia, cirrhosis of the liver, heart lesions, tumor pressure, secondary chronic hyperemia, and amyloid disease, may all con- tinue diarrhea during periods of varying length, according to the nature of the primary disease and the ability of the patient to resist. Chronic lesions within reach of the eye (rectal, sigmoid) which are non-malignant, with modern methods of recognition and local treatment, offer a good prognosis if not too far advanced. Productive changes and distortions secondary to dysentery are purely surgical affections; strictures of the rectum or sigmoid may continue chronic diarrhea, as may also chronic constipation and malignant constric- tions. Frequent, small stools, often unsatisfactory stools, should always 626 DISEASES OF THE DIGESTIVE APPARATUS create the suspicion of an unrelieved bowel, just as frequent unsatisfac- tory urination, is evidence of retained urine. Diagnosis and prognosis of all forms of chronic diarrhea are materially advanced by the repeated consideration of the general condition of the patient, for in unexplained diarrhea suspicion should fall upon several vital organs, including kidney, liver, heart and nervous system. {Chronic Enteritis of Warm Countries, Aphthae tropical, Aphthae orientates, Psilosis linguae et mucosae intestini) Sprue With sprue the entire mucosa of the intestinal tract is involved in a chronic and remitting inflammation which seems to attack Europeans mainly, living in tropical or subtropical climates. The tongue and mouth are mainly involved in superficial ulceration; the mucosa is hyper- sensitive, Avhile the intestinal lesions cause diarrhea. The disease is occa- sionally brought to our country; in the tropics it may complicate other forms of enteritis. Thin has suggested the name of “psilosis” because of the raw appearance of the tongue and intestinal mucosa. Manson says: “Of all the chronic diseases the European has to contend against (in South China), sprue, in its various forms and degrees is by far the most frequent as well as the most formidable.” The bacterial cause of sprue is uncertain. Whatever its cause finally proves to be, the peculiar history of the disease, its chronicity, long periods of latency and recurrence (patients without returning to the source of infections years after the initial symptoms, developing anew the symp- toms) will require consideration. Unless relieved, the loss of flesh and strength with anemia and heart weakness associated with the “primary and secondary effects of starvation” (Manson) may cause death. The organic changes in the intestines, gastric mucosa, as Avell as in the upper portions of the alimentary tract, may be deep and variable. They include follicular changes, ulcerations, atrophy, infiltration of the mucous mem- brane (leukocytic), and in the more chronic types, fibrotic or productive deposits throughout the small and large intestines. When the disease is limited to catarrhal changes, full recovery is possible. The deeper changes above mentioned are secondary in all prob- ability to long continued and unrelieved catarrhal processes, and while symptoms may be partially overcome, the organic changes remain. In all the cases seen in this country, the tongue lesions have been prominent and painful. These cases, unless relieved, progress; emaciation advances and is excessive; the patients resemble the reconcentrados of the Cuban War; the urine is albuminous, edemas and general dropsy follow with increasing uncontrolled diarrhea, death results from starvation. The prognosis depends entirely upon removal to proper quarters and proper DISEASES OF THE INTESTINES 627 food during the early stage of the disease—before the mucous membrane of the alimentary canal has been destroyed. The clinician should not be deceived by periods of marked improvement or latency; he must guard his prognosis because of the tendency of relapse even after years of free- dom as already suggested (See references for history and literature). 3. Diarrheal Diseases of Early Childhood I have repeatedly in the preceding pages referred to the infections of the infant which lead to diarrheal diseases, and have considered their prognosis. The campaign of education which has led to clean and pure milk has done much to reduce infant mortality. He who practiced during the days when ignorant of the causes of intestinal diseases thousands of infants were annually sacrificed, and who is privileged to note the change which has followed the dissemination of knowledge among the masses and the medical profession, is deeply impressed by the favorable advance. Prophylaxis is possible in all communities and in all families wher- ever concerted action of the profession and responsible head of the house obtains. The reduction of mfant mortality from diarrheal diseases is the problem of the state and the municipality. Infant mortality will be re- duced to an almost negligible factor when ideal conditions prevail. What they are, the profession understands; it remains only for the profession to demonstrate these to the lawmakers that competent health officers may co- operate with every household. Besides the prophylactic factors which can be easily controlled, the baneful effect of humidity and high temperature on infant mortality due to diarrheal diseases must be considered; to these factors must always be added bacterial contamination (the Shiga bacillus usually). The change which has resulted in infant mortality is best understood when the mortu- ary records of large cities are considered. Naturally the death rate is lower from cholera infantum and other diarrheal diseases of early life during favorable summers. In London, as in all cities, the science of infant feeding has progressed and the mortality during all years since 1906 has been materially reduced. The last (1910) census of the United States shows for the registration area as a whole, the general death rate was 15 per 1,000 population for 1910, including an element due to infant mortality amounting to 2.9 deaths of infants under 1 year, and 4 deaths of children under 5 years per 10,000. There were 44,695 deaths of infants under 1 year of age from diarrhea and enteritis. The previous census, 1905, published in 1907, shows that in 1905 the death rate from diarrheal diseases was higher than during the preceding four years. 628 DISEASES OF THE DIGESTIVE APPARATUS CENSUS OF 1905.

The total number of deaths of infants under 1 year for 1910 was 154,373—one-fifth of all deaths (19.2 per cent). During the second year 33,080, or 4.1 per cent of the total. Of 58,089 deaths of infants under one month 5,901 were due to diar- rhea and enteritis. Beginning with the second month of life diarrhea is the most serious cause of infant mortality. Of 15,223 deaths of in- fants 1 month of age and under 2 months, 4,692 were from diarrhea and enteritis. Infants 2 months of age and under 3 showed 4,980 deaths from diarrhea and enteritis.

The rate of infant mortality as given by English and continental cities where the registration is practically correct are encouraging. The fob- lowing from the annual summary of the Registrar-General of England : The decrease per cent between 1881-1885 and 1906-1910: in Lon- don 24.0, Edinburgh 6.3, Paris 34.6, Amsterdam 55.7, St. Petersburg 6.8, Berlin 41.3, Hamburg 32.4, Munich 42.6. The features which make the prognosis of cholera infantum had are weakness and lack of resistance, collapse, high temperature, rapid pulse, profuse watery depleting stools, convulsions, great restlessness, dry to7igue, reduced quantity of urine, tenesmus and uncontrollable vomiting. With irregular respiration and opisthotonos the prognosis is also bad; also with bronchopneumonia or other complications. Enterocolitis, ulcerative enteritis and membranous enteritis of child- hood are considered in the preceding pages of this chapter. The mortal- ity of summer diarrhea is always higher when the Shiga bacillus and streptococcus are present. The mortality in the presence of the gas bacilli, averages between 40 and 60 per cent in large cities. When acid move- ments are improved by proteid food the prognosis is accordingly better. Schmidt’s bile test in the summer diarrhea of infants has been thor- oughly tested for its prognostic value by Pearson. It has been established that zymotic enteritis (infectious) is associated with a marked diminution in the secretion of bile; in the cases which come to the post mortem room, according to Pearson, the tests for bile remain negative throughout the intestines. In a series of 500 cases with the “proper secretion of bile restored, and no other complication—such as bronchopneumonia—the cases invariably recover.” In Pearson’s latest publication he says: “The point I wish to lay stress on is that in over 2,000 cases of acute summer diar- rhea (of infants) I have never lost one in which the Schmidt test * con- tinued, or after treatment became positive. With as much emphasis I may say that I never managed to cure one case in which the test con- tinued negative.” 4.

By this time feces if normal becomes colored bright red, showing the presence of hydrobilirubin or stero-bilin, but if unchanged, bile pigments are present and the color becomes green.

These children lose flesh and strength progressively; there is marked muscular weakness; in some there is threat- ening, at times, fatal tetany, and a number of writers have found infantil- ism, result. This type is exceedingly chronic, and improvement is often followed by repeated relapse and death. The fault lies in the failure of the child to digest fat and starch, and unchanged fat is found in the stools. These cases may be so severe as to suggest tuberculous enteritis and tabes mesenterica. In rare cases there have been ulcers. The substitution of raw minced meat or meat juice, improves most cases. References Aschoff. Pathol. Anatomie. Jena, 1913. Hillary.

Enteroptosis (Glenard’s Disease) See Diseases of the Stomach—Section V, F-4. 6. Constipation—Obstipation Constipation is as a rule a functional disorder, for which the patient is largely responsible. It is a.physiologic fact that different people differ as to the frequency of bowel movement. There are women (rarely men) who continue perfectly well with one movement every two to four days. In most cases chronic constipation leads to or is associated with more or less disagreeable symptoms, mental depression, languor, drowsiness, in- ertia, anorexia, foul tongue and breath—and in young girls particularly— anemia, with other toxic symptoms. Individual predisposition is an im- portant etiologic factor, as is also heredity. Habits and diet are paramount and their correction, almost at once re- DISEASES OF THE INTESTINES 631 lieves the atony which continues constipation. Sedentary habits are pro- ductive of intestinal inertia. Faulty diet includes an excess of one article to the exclusion of many others. Sweets (candy), starches in excess, are leading faults which cause constipation. Insufficient fluids (water) and fats will often con- tinue constipation until the deficiency is supplied. Procrastination is one of the prominent causes of constipation. The habit of moving the bowels at the same time each day is easily and promptly formed even in chronic cases. Mental emotion, long continued worry, circulatory diseases, gastro- intestinal diseases including the neuroses, also central nervous diseases, as brain tumor, spinal lesions, compression of the spine (caries and tumor), are all provocative. The mechanical obstruction of the intestine at one or more points is not true constipation, but is considered with intestinal obstruction—either partial or complete. Pregnancy is a frequent cause of constipation. Chronic constipation may be diagnosticated when the bowels refuse to move without assistance, either by medicines or mechanical means. In all forms of obstipation in which correction of existing faults fail to overcome the symptoms, organic disease should be strongly suspected. Thorough search will usually reveal either a rectal anomaly, uterine or other pressure, or some positive cause, either intestinal or remote. Among the conditions which are often overlooked as causes of obstipation are chronic intestinal catarrh, lead poisoning, general asthenia and the func- tional gastric neuroses. Secretory anomalies, without organic change, when corrected, either in the stomach or intestines, cure constipation de- pendent upon them. The atonic form of constipation is dependent upon (a) reduced intes- tinal peristaltic activity, or (b) there is insufficient expulsive strength which includes enfeebled action of the diaphragm and abdominal walls. (a) Reduced Intestinal Peristaltic Activity. — Reduced intestinal peristaltic activity may follow long continued fevers or non-infectious diseases. It depends largely upon neural disturbances. It is frequently an expression of the neurasthenic complex—hysteria, inertia, central dis- ease—and in the majority of cases is due to improper stimulation of the intestinal mucosa because of the faults mentioned in the preceding para- graphs. In most cases in which reduced intestinal peristaltic activity is the paramount factor the regulation of the life of the patient, including proper exercise, diet and regularity in the attempt to move the bowels at the same time each day, though not at once successful, will always in the end prove efficient and if continued cure the bad habit. Neglect will provolce recurrence. Rectal torpor is a frequent and unrecognized cause. (b) Insufficient Expulsive‘ Strength.—Many causes of insufficient 632 DISEASES OF THE DIGESTIVE APPARATUS expulsive strength are finally overcome. They include pregnancy, inherent weakness of the abdominal wall, asthenic conditions which include ven- tral and diaphragmatic weakness, malnutrition, obesity, abdominal growths, faulty exercise, organic disease of the heart, lacerations of the perineum, and constitutional diseases such as diabetes, gout, leukemia, etc. Painful affections of any kind, fissure in ano, hemorrhoids, neuritis, in which the pain is increased by pressure, lead the patient to procrasti- nate. Masturbation and sexual excesses may provoke both intestinal atony and insufficient expulsive force. Travel is another important factor. In children there may be idiopathic dilatation of the colon with en- feebled expulsive force, at times rectal torpor to keep up constipation (Hirschsprung’s disease). Spastic constipation is due to a spasmodic contraction of the intes- tine over separate fecal masses, usually found in nervous patients and first described by Fleiner, in which there are functional intestinal stenoses. The peristaltic unrest of the intestinal coils is recognizable. The move- ments are preceded, often accompanied with colic. The sphincter mus- cle of the rectum is also tense. Many of these cases are due to toxic influences (tobacco, excessive use of alcohol) and often the neurasthenic character is demonstrated by the association of membranous enteritis. Of late attention has been called to a condition in which there is claimed to be abnormal movement of the cecum (cecum mobile). Wilms first called attention to this condition. The leading features are consti- pation and pain in the right ileocecal region. The acceptance of mobile cecum as a cause of the symptoms mentioned has not yet followed, and I have seen several cases in which operative interference, in no way influ- enced the complaints; indeed the cecum is usually found abnormally mo- bile without causing any symptoms. Schmidt does not believe that the cecum mobile represents a clinical entity; the normal cecum is more or less mobile. The pathologic condi- tion which causes abnormal mobility depends upon an abnormal mesen- tery and changes in the walls of the cecum. There are congenital anom- alies of the ileocecal mesentery, diseases of the appendix, fcnteroptosis, obstipation, which may cause typhlatonia, also known as typhlectasia. These cases are both medical and surgical and offer a good prognosis. Spastic conditions may be assumed to be due to insufficient moisture and too great hardness of the feces; old adhesions should always be con- sidered possible as should other and graver lesions. We are fully con- vinced that the majority of constipations will yield after the correction of their removable causes, though often exceedingly rebellious. The individual case, in order to make the prognosis good and to prevent re- lapse, will demand thorough study and the greater success will always follow natural methods of treatment. Constipation may be considered a bad habit when not due to organic disease of which the patient can be DISEASES OF THE INTESTINES 633 relieved; the condition is never dangerous hut it often makes the victim wretched and unhappy, handicaps him physically and mentally and often keeps up a continuous autosuggestion which tends to exaggerate the im- portance of the symptom enormously. The habitual use of cathartics never cures constipation. Reference Schmidt. Zur Frage d. Coecum Mobile. Bruns Beitr. z. klin. Chir., 1913, Bd. Ixxxiii, p. 639-43. 7. Intestinal Obstruction (Ileus) While intestinal obstruction—a condition in which the intestinal con- tent cannot be forced beyond an existing narrowing, usually mechan- ical, and of organic origin—is a surgical affection, it is almost invariably presented to the physician first for diagnosis. Obstruction may be (a) partial or (b) complete. In all, x-ray exami- nation may prove of inestimable diagnostic and prognostic value. (a) Partial Obstruction When partial obstruction causes but moderate stenosis (narrowing of the lumen of the intestine), the symptoms do not threaten life, con- stipation is prominent, persistent, and is only temporarily overcome with considerable difficulty until the prime cause is removed. There are a variety of causes of partial intestinal obstruction; some of these may never lead to complete occlusion, others may. During the early days or months of grave intestinal disease, as carci- noma or extra-intestinal pressure, there may be only partial obstruction which as the disease progresses may lead to increasing obstruction and final occlusion. Most growths do not lead to complete intestinal obstruc- tion. The symptoms produced by partial intestinal obstruction depend much upon its location, cause, and the degree of constriction. It may be assumed that any narrowing of the small intestine is more likely to produce serious and threatening symptoms than is stricture of the large intestine. It is not at, all uncommon to find intestinal lesions post mortem, with narrow- ing of the small intestine distant from the pylorus or ileocecal valve, with- out having caused symptoms during life. This would hardly be possible with obstruction within the duodenum or at the ileocecal valve. The partial narrowing of the large intestine at any point above the sigmoid flexure may be present, even due to malignant disease without symptoms and without threatening life during long periods (See Intestinal Cancer). 634 DISEASES OF THE DIGESTIVE APPARATUS Partial obstruction may be due to removable pressure—such as pelvic growths or tumors elsewhere in the abdomen—which may by pressure, ad- hesions or transitory causes narrow the intestinal lumen. The most fre- quent cause of partial as well as complete obstruction to the emptying of the intestines is fecal accumulation (40 per cent), which may follow obstipation, or adynamia (enfeebled intestinal peristalsis) from a vari- ety of causes. Gall-stones within the intestines or by adhesions of the gall-bladder may cause incomplete obstruction. Chronic adynamic partial obstruction may be an expression of general enfeeblement; it may be an accompaniment of central disease of the nervous system (tabes dorsalis, brain tumor, chronic meningitis, cerebral apoplexy, or other serious organic lesion). Chronic morphinism has in two of my cases caused fatal adynamia. Following abdominal surgical operations, intestinal obstruction due to acute adynamia is a serious and at times fatal combination. In such cases all of the symptoms of com- plete and organic obstruction may precede death. The prognosis of these adynamic cases following abdominal operation is grave. Most partial intestinal obstructions are amenable to treatment; life is not threatened, as a rule. The organic causes are purely surgical and demand radical treatment, for most of them are progressive. Large fecal accwmulatmis and most gall-stone obstructions within the intestines yield without rad- ical surgical treatment (See also later paragraphs). Partial intestinal obstruction may exist with continuance of unsatisfactory, at times, fre- quent movements; this is an important diagnostic as well as prognostic fact. (b) Complete Intestinal Obstruction The majority of all organic obstructions are found in the male (65 to T5 per cent) and almost one-half between the ages of 15 and 30. Be- tween 85 and 95 per cent are in the small intestine, and as Fitz, Treves, Leichtenstein, Wiggins and others have demonstrated, two-thirds are in the ileocecal region and four-fifths in the lower abdominal regions. The various forms of intestinal obstruction are found at different ages; strangulation by bands is most frequent in advanced life and with the preceding history of peritonitis. Hernial obstruction does not often hap- pen early in life. Intussusception or invagination is a complicaton of early childhood. Complete intestinal obstruction is always a life-threatening condi- tion. It demands immediate diagnosis and prompt radical treatment in almost all cases. This is true of all cases within the small intestines which arise suddenly; the gradually increasing obstructions and final complete occlusion are less malignant, but they too when located in the small intestines offer the same doleful prognosis, though the septic condi- tion may be less virulent. Complete obstruction of the large intestine Q,t DISEASES OF THE INTESTINES 635 the sigmoid may exist during weeks without causing the symptoms which promptly follow occlusion of the small intestine. Enormous dilatation of the large intestine above the stricture and surprising tolerance has characterized some of my cases. Sepsis, peritonitis, and final cardiac toxemia are the leading dangers of complete intestinal obstruction. Complete intestinal obstruction may be acute, without preceding symp- toms. There is no warning, but suddenly the “acute abdomen” is devel- oped with associated subjective and objective features at once suggestive of a grave intra-abdominal (intestinal) lesion. Acute obstruction may suddenly develop in cases in which during a variable period there have been evidences of chronic partial obstruction; and finally chronic intes- tinal partial obstruction may gradually increase stenosis until it becomes complete. The features of complete occlusion which influence prognosis unfavorably are suddenness of onset, shock, prompt peritonitis, profound sepsis, fecal vomiting with increasing abdominal distension, strangury, pinched and characteristic facies, cold extremities with cyanosis, and rapid small and thready pulse with hypotension after a short initial period of rise of blood pressure. Hiccough is an exhausting symptom and is not relieved while the obstruction continues. Indicanuria is always present when the small in- testine is obstructed, often with constriction of the large gut. Albumi- nuria is not constant but is unfavorable when present with casts. Com- plete intestinal obstruction may be due to: (I) Strangulation by bands or adhesions and incarceration (hernia) (II) Volvulus (III) Intussusception (IV) Stricture (V) Tumors or foreign bodies in the bowel (VI) Extra-intestinal pressure (from tumors, etc.) (VII) Eecal accumulation. In order of frequency following fecal accumulation the leading or- ganic causes are: 1st. Strangulation by bands or adhesions and incarceration 2d. Intussusception 3d. Stricture within the intestine 4th. Extra-intestinal causes 5th. Tumors or foreign bodies in the bowel 6th. Volvulus. The typhlitis stercoralis of the Germans is a condition in which there is impaction of feces in the colon wfith tumor formation and localized 636 DISEASES OF THE DIGESTIVE APPARATUS symptoms, with features simulating obstruction and appendicitis. The prognosis of this condition is good. Multiple growths or tumors within the abdomen may cause symptoms simulating fecal impaction, and require cautious differentiation* Causes of Complete Intestinal Obstruction (1) Strangulation.—Strangulation or obstruction by bands and in- carceration (hernia) through apertures was found- in 35 per cent of 295 cases of organic obstruction by Fitz. Treves includes (a) Ligaments (false) following peritonitis (b) Omental cords (c) Meckel’s diverticulum (d) Normal structures abnormally attached (ovarian, etc.) (e) Incarceration through slits and apertures (herniae) (f) Isolated bands and adhesions. (a) False ligaments following cured peritonitis may suddenly cause obstruction, or obstruction may be sudden after a long period of increas- ing symptoms, particularly “ballooning” or “sausaging” of the intestine above the constriction. The intestinal wave and distention with gurgle and collapse are easily recognized by watching the abdominal wall. The sudden and repeated ballooning of the intestine is a symptom of great value. It is always indicative of partial obstruction and should be heeded; when it is properly interpreted in time, and treatment in operable cases is not postponed in the absence of complications, the prognosis is excellent. A small short or a long slender band may exist a long time without causing symptoms until a loop of intestine slips under it, and once held, the occlusion is complete. All die unless relieved surgically. The excep- tions to this rule are so few as not to deserve consideration. (b) Omental cords may cause strangulation with all of the symptoms of concealed hernia. A loop of intestine may rest in a hernial opening unobstructed, but above it a thin omental cord with adherent omentum may continue the strangulation after the hernial sac has been emptied. Unrecognized, such a complication is fatal. Omental strings and cords with fixed omentum should always be suspected when obstruction is not otherwise explained. (c) Mechel’s diverticulum.—My experience with Meckel’s diverticu- lum proves that when it throws itself around the intestine and forms a knot, only radical treatment can save the patient. Diverticulum strangu- lating the gut leads to prompt collapse, usually a profound septic state, and strangury or scanty urine with enormous indicanw'm in the little urine voided. DISEASES OF THE INTESTINES 637 (d) Normal structures abnormally attached by adhesions, organs ad- herent to each other, "balling” of intestines, after repeated peritonitis, at times adhesions to the abdominal wall, may by traction or compression cause obstruction. I have before the days of improved abdominal sur- gery seen tumor formation due to the agglutination described, with sud- den acute or chronic partial obstruction gradually followed by complete closure. The prognosis of these conditions is not favorable when a part of general chronic peritonitis; when limited, recovery may be expected to follow surgical treatment in a large proportion of cases if instituted early. (e) Incarceration Through Slits and Apertures' {Hernia).—Isolated bands may form slits or apertures which intestines enter to be strangu- lated. When in the neighborhood of the appendix, appendicitis is simu- lated, the McBurney point is included, and procrastination will surely cause death. Experience with early operation in such cases has been favor- able. I had one tabetic woman who had previously repeated gastric crises; I mistook the incarceration of a loop of the ileum into the ischiatic notch for a crisis—the symptoms were identical; when the correct diagnosis was made, the gut was found gangrenous and I lost my patient. Such a com- bination is exceedingly rare but with the warning and experience, the error ought not to be repeated. I have seen large and small intestines agglutinated with resulting obstruction and relief from operation. The herniae belong entirely -within the domain of the surgeon and rarely come to the internist. If the majority of intestinal obstructions are to be saved, the inguinal, femoral, and umbilical openings should be sus- pected and examined, in spite of a. negative previous history. (f) Isolated Bands and Adhesions.—I have considered these cases in connection with (e) incarceration through slits and apertures, for iso- lated bands may hold a loop of intestine, or adhesions with or without isolated bands may cause obstruction. (II) Volvulus.—The gut sometimes circles or twists on itself in such a way as to narrow its lumen or completely occlude it. Fitz found 42 cases of volvulus (twists) in his 295 cases. About 70 per cent were males. One-half were sigmoidal, and in most there was an axial twist of the gut. The average age was between 30 and 40. The cecum is fre- quently the seat of volvulus; the ascending colon and small intestine less frequently. The prognosis of complete obstruction due to volvulus is good when operated early. If the large intestine is involved, the shock is less; the urine is not likely to be entirely suppressed and indicanuria is slight or absent. (III) Intussusception (Invagination).—Intussusception is a com- plication of early life. The telescoping brings the six layers of the in- vaginated gut together (layer to layer) peritoneum to peritoneum, and if held long enough, strangulation leads to gangrene, at times to slough- DISEASES OF THE DIGESTIVE APPARATUS 638 ing and passage of the slough. In these cases it occasionally happens that nature’s processes coapt the intestine and life is thus saved. In one of my cases twelve inches of gut was passed and the child lived. Osier reports one case in which 17 inches sloughed with recovery. Fitz’s cases (295) were due to invagination. Lichtenstein found 52 per cent of his cases ileocecal or ileocolic, 30 per cent enteric, and 18 per cent rectal and colico-rectal. In children invagination may be without known cause; it may com- plicate infections (measles), constipation, or diarrhea. Wiggins reported 103 cases in early life of which 50 per cent were between four and six months of age. Nature’s method (sloughing) and surgery, offer the only hope of sav- ing life. (IV) Stricture.—Stricture leading to complete occlusion and intes- tinal obstruction may be due to (a) cicatrization (b) carcinoma (c) congenital defect. (a) Among the causes of stenosing cicatrization are hernia, typhoid fever, dysentery, catarrhal ulcers, syphilis, and tuberculosis. In all of these there is a characteristic previous history of chronicity with long periods of gradually increasing symptoms (ballooning and collapse of intestine after gurgling), and when these symptoms are unheeded com- plete obstruction may follow. (b) Carcinoma and other neoplasms are not often causes of complete obstruction because their favorite seat is in the large intestine, in the sig- moid flexure, or descending colon. When there are annular constrictions, benign or malignant, near the ileocecal valve they may cause complete obstruction. Cancerous infiltration of the ileocecal valve and appendix are proved to be increasingly frequent as removed specimens are being microscopically examined. When carcinoma or other neoplasm causes obstruction, surgery must be invoked. The diagnosis can, in almost all cases, be made with sufficient accuracy to justify exploration long before occlusion. (c) Congenital defects are usually found in the rectum (imperforate anus or union of the pylorus and duodenum has failed). Almost all of these infants die. (V) Tumors or Foreign Bodies in the Bowel.—Among the tumors of sufficient size to cause obstruction are polypi, fibroma, lipoma, sarcoma and carcinoma. The foreign bodies are gall-stones, indigestible food, foreign substances swallowed (glass, metal and a large variety of material) and enteritis. When gall-stones are of sufficient size to obstruct the intestine, they gain entrance after adhesive and localized peritonitis DISEASES OF THE INTESTINES 639 has been protective during the process of ulceration. The vagaries of gall-stones are many and Courvoisier and Eisner have reported interest- ing experiences which hear on this subject. The majority of large gall- stone masses which obstruct the intestine pass per rectum. Obstruction may, with gall-stones, continue during many days and yet recovery may follow. There is danger of subsequent perforation and peritonitis, but that is comparatively small. I have never been forced to resort to sur- gery after the stone has entered the intestine, though extra-intestinal adhesions of the gall-bladder filled with gall-stones causing obstruction almost always in the presence of threatening symptoms demands radical treatment. Enteroliths may occasionally demand surgery to save life. Obstruc- tion due to foreign bodies offers a favorable forecast; those dependent upon the tumors above mentioned when non-malignant, are favorable for surgi- cal treatment. The malignant growths within the intestine when suffi- ciently advanced to cause obstruction are likely to have metastases and adhesions which darken the outlook. In 44 of Eitz’s cases of obstruction due to foreign bodies 23 wTere gall-stones, 19 were fecal masses, and 2 were enteroliths. (VI) Extra-intestinal Pressure (Tumors, etc.).—Pelvic growths, tumors of the uterus and ovaries, pelvic abscess, retroperitoneal growths, large malignant masses connected with one or more of the abdominal or- gans—kidney, spleen, liver and suprarenal tissue (hypernephroma), tuber- culous masses and associated adhesions—may each by pressure or trac- tion cause obstruction. The prognosis must depend upon the operability and the complications of the individual case. (VII) Fecal Accumulations.—We have in several of the previous paragraphs mentioned fecal accumulation as a cause of incomplete and complete obstruction, in all of which when uncomplicated, the prognosis is good. We once more call attention to adynamic or 'paralytic ileus when neglected with fecal accumulation, in which the prognosis is always seri- ous. With infarct involving the mesenteries and the abdominal wall as a cause of adynamic obstruction, the prognosis is exceedingly grave. Whenever there is organic, complete, acute, intestinal obstruction, the life of the patient depends upon the diagnostic ability of the physician, and the full appreciation of his responsibility which must lead to imme- diate surgical consultation and radical surgical treatment. I offer no statistics because they are valueless, owing to the faulty classification of the included material. References Courvoisier. Causuistische statistisch Beitrage z. Path. u. Chir. d.

Dilatation of the Colon Hall White divides dilatation of the colon into four groups, in all of which Rontgen rays may prove of great assistance: (I) Distention Due Entirely to Gas.—There is no obstruction or organic lesion. It may be an accompaniment of acute infection (typhoid fever, peritonitis, tuberculous peritonitis, traumatism, or severe nervous diseases). The result of pressure may be exceedingly troublesome, in some cases causing heart and lung symptoms, and there is extreme distention of the abdomen. When with pneumonia or chronic heart disease there is dilatation of the colon and stomach, the combination is exceedingly grave, and unless relieved may cause death. (See Pneumonia, also Acute Dila- tation of the Stomach.) (II) Distention of the Colon With Solid Matter Within It.—This may be due to faulty diet, coarse food, hard fecal matter, hair and other foreign substances. In the insane the swallowing of foreign bodies is a frequent cause of dilated colon; enormous gall-stone masses which have ulcerated through the intestinal wall may prove causative. Excess of lime phosphate in the stool,insufficient water, typhilitis ster- coralis, are among the causes. Treatment and careful attention to the diet, watching the patient, thus preventing the swallowing of foreign bodies usually overcome the condition. (III) Organic stricture, or compression of the large intestine beyond the dilatation, leads to hypertrophy of the muscularis when chronic and secondary changes (catarrhal colitis, ulceration, etc.) follow. The prog- nosis of these cases depends entirely upon the ability of the surgeon to remove the cause. (IV) Hirschsprung’s disease, or idiopathic dilatation of the colon —a congenital defect—is also mentioned in this section in connection with constipation (Section V, G. 6, Constipation). The dilatation, if the children live, is marked and nearly fills the abdomen. The dilata- tion is often progressive. There is great danger from tetany; obstipation is severe. The children are otherwise imperfectly developed and often show infantilism. Acute intestinal obstruction is a fatal complication in occasional cases, and is the most serious complication. I have occasion- ally met idiopathic dilatation of the colon in the adult, usually between DISEASES OF THE INTESTINES 641 25 and 30, without known cause, exceedingly rebellious to treatment with neurasthenic symptoms and cardiac neuroses. Life was not threatened. Crozer Griffith reported 24 cases from medical literature of idiopathic colon dilatation. Osier reported a case of a boy aged 10 years with enor- mously distended abdomen in which there was diarrhea, vomiting, and visible intestinal peristalsis. Medical and mechanical treatment were of no avail. When the abdomen was opened, no stricture was found; “the sigmoid was 18 inches in circumference, the cecum was half this size, and the bowel progressively increased in size from the cecum to the sigmoid which was folded on itself, but not so as to cause any ob- struction.” An artificial anus was made. There was improvement; he gained in weight; he lost his tympany but the artificial opening was never closed. But few of the congenital cases reach adult life; Kredel believes if they do, they may reach old age. I am fully satisfied that idiopathic dilatations of the colon occurs in the adult without congenital anomaly, and when it does, unless great caution in diet and exercise is practiced, it remains a chronic and annoying condition, uninfluenced by medicine but with many subjective and positive objective manifestations. Surgery offers hope of relief. References Bristowe. Brit. Med. J., 1885, i, 1085. Crozer (Griffith W.). Am. J. Med. Sci., 1897, cxviii. Kredel (L.). Ztschr.f. klin. Med., 1904, liii. Nothnagel.

Aschoff classifies diverticulum as either true or false. The false diverticulum is characterized by coves in the intestinal wall in which the hollow opens into the muscularis and causes prolapse of the mucosa. The true diverticulum is characterized by a localized excavation of a part of the intestinal wall in which the mucosa is included. The one (false) is a mural, the other (true) is a diverticu- lum of the mucous membrane. The false is included between the mucosa and peritoneal covering of the gut. The true diverticulum is usually congenital. The intestinal surface has the appearance of partial perfo- ration and the coves are most abundant and usual at the sigmoid flexure. 642 DISEASES OF THE DIGESTIVE APPARATUS The appendix may be involved, and unquestionably appendicular diver- ticulum is a cause of appendicitis. Diverticulum may be single or multiple. The acquired diverticula are found in advanced life. Diverticula may lead to obstipation, pocketing, inflammatory condi- tions (diverticulitis and perisigmoiditis), giving rise to serious symptoms. Intestinal obstruction may be caused by Meckel’s diverticulum (See Intestinal Obstruction), or the smaller multiple or single diverticula may lead to stricture with consecutive dilatation, gangrene, ulceration, per- foration, fistula formation (vesico-colic fistula) and distant suppuration, also thrombosis (phlebitis). In elderly subjects carcinoma is simulated. A surprisingly large number of physicians have recently suffered from the disease and have been successfully operated (resection). The results at the Mayo and other clinics where a large number of cases have been detected, have been surprisingly satisfactory. Unfortunately the diag- nosis is not usually easy. Where there are persisting and increasing symptoms the condition should at least be suspected; Rontgen rays should be used to assist in diagnosis. As a rule, sufficient time for radical treat- ment precedes the graver complications. References Aschoff. Pathol. Anal. Jena, 1913. Matthes. von Mehring termine the variety of the bacterial infection. Bacterial virulence and proliferation are invited by the inability of the peritoneum to take ad- vantage of its “factors of safety,” or normal protecting power. Thus in the presence of fluid in the cavity (injury or disease) with ascites, as in nephritis or other lesions, with perforation, and foul and other foreign matter, the protective agencies are reduced, and proliferation is invited; virulence, as suggested, is increased. These facts are sufficient to explain the rapid development of acute peritonitis following injury to the abdom inal wall, the breaking of adhesions, perforations, uterine lesions, salpin- gitis and the many other primary diseases which promptly cause the second- ary disease. In the preceding chapter I considered the association of peritonitis with appendicitis—the most frequent of all of the causes. I have also considered peritonitis as it complicates the various intestinal obstructions, including hernia and constriction due to intraintestinal les- ions, with the perforation of typhoid, stomach and duodenal ulcer, also malignant ulceration and perforation, gonorrheal and puerperal infection of the genitalia, and their dependencies. It would be a work of superero- gation to again dilate on each of these. The resulting peritonitis offers the same general picture; its gravity is always the same though the viru- lence and malignancy of the infection does influence the resistance of the individual, but with all the rule holds that it is the rare exception for a case of general peritonitis, in which the cause has not been promptly re- moved, to recover. Once peritonitis is general from whatever cause, the chances of saving life are exceedingly small. Septic (streptococcus) peri- tonitis leads to such profound toxemia as promptly to rob the patient of heart strength. Localized and protective peritonitis is often a life saving process, for by the throwing out of plastic material and its organization it protects against general and septic peritonitis. This is often true of ulcerative intestinal diseases (appendicitis, intestinal, gastric, duodenal ulcer, and gall-bladder disease). Subphrenic abscess is considered with ulcer of the stomach and duo- denum ; for its clinical study Maydl’s monograph is a classic. It may he assumed that the sudden development of general peritonitis following perforation of a hollow viscus, without preceding protective peritonitis, is among the most serious forms—almost always fatal unless de- tected at once and relieved by surgical treatment (perforative peritonitis). DISEASES OF THE PERITONEUM 661 In these cases the Streptococcus pyogenes is usually found, the albus is less virulent. In children the pneumococcus is among the more malignant of the bacteria present (Rischbieth). The gonococcus in my experience is less virulent than the streptococcus and often leads to a subacute or chronic course. Prognosis is materially influenced by the resistance which rugged health and the normal previous conditions offer. Young children particularly offer a bad prognosis in acute peritonitis from any cause. Acute Diffuse Peritonitis with Appendicitis.—With appendicitis (the usual cause) diffuse peritonitis once developed is almost uniformly fatal. The unfavorable features are pronounced abdominal distention, obstipa- tion, fecal vomiting, hiccough, pinched features, reduced and albuminous indican-laden urine, small pulse, rapid heart, hippocratic facies, and cold extremities. Never have I seen but two patients recover with this symptom complex. The Temperature.—The temperature in the midst of fully formed symptoms is not to be depended upon as a prognostic index. Prompt collapse with subnormal temperature in the early hours of peritonitis is only occasionally followed by a happy result. High temperature is un- favorable in the presence of other advancing symptoms. Extreme rest- lessness and insomnia, are always unfavorable. The average duration of fulminating or perforative appendicitis is rarely beyond forty hours. Treves mentions cases in which the peritoneal symptoms are less prominent than is the typhoid condition. These are in aged and previ- ously reduced individuals. Kidney and Liver.—Among the serious secondary lesions are those which involve the kidney and liver. The rapid advance to the liver through the portal circulation of toxins from the abdominal cavity and to the kidney lead to parenchymatous changes. These add factors of enormous danger. Puerperal Peritonitis.—Puerperal peritonitis is fortunately rare when modern methods are used during labor; it is a streptococcus infection, is probably of lymphatic origin, and spreads from the uterus to the peri- toneum. Continuous fever with rapid pulse is less favorable than re- mission with profuse sweat, following chill and fever. It is a true septicemia. The mortality is rarely below 50 per cent in developed cases. Further Considerations.—In all forms of the disease the more favor- able cases are those in which the intestinal paresis is not complete, and there are occasional movements with fair quantity of urine and a heart which is without the asthenia of extreme toxemia. When the pulse is persistently at 120 and above, the condition of the patient is threatening, ■whether before or after operation. The conclusions offered in considering the blood picture and appendicitis, are equally true of peritonitis. High leukocytic counts are not encouraging—low counts are equally unfavorable. 662 DISEASES OF THE DIGESTIVE APPARATUS Diffuse peritonitis as a rule, when it is not controlled within the first 30 hours, is fatal. I have learned to place great reliance in prognosis on the facies of the patient. Changed facies, pinched appearance, means death. Of Treves’ 70 fatal cases 14 per cent died within 36 hours, 6 per cent be- tween 36 and 48 hours, 20 per cent between the third and fifth day, 33 per cent between the fifth and seventh day, and 27 per cent after a week.

Chronic Peritonitis After acute localized peritonitis there is organization of tissue (produc- tive peritonitis) which leads to thickening and adhesions (periuterine, perigastric, perisplenic, periappendicular). In occasional cases there may be pus accumulation between the layers of new tissue. Such abscesses are naturally encapsulated and usually operable, and offer a good prog- nosis. These include appendicular and subplirenic as well as other ab- dominal abscesses. Deforming and obliterating peritonitis or adhesive peritonitis follow' in those cases of agglutination in which after acute or subacute peritonitis or the tuberculous variety, the coils of intestine or organs are so firmly united as to make separation impossible. The peritoneum is obliterated, and <(deformed.” Such complications are also likely to follow extensive abdominal operations. Periserositis (See Pick’s Disease and Periserositis) may also b© in- cluded among the chronic types. In these cases besides the spleen, the liver, general peritoneum and pericardium are included. The great dangers of localized and obliterating chronic peritonitis, are possible intestinal obstruction and chronic invalidism, due to the effect of adhesions, bands, distortions, and the changed relations of organs. In- DISEASES OF THE PERITONEUM 663 testinal obstruction due to fibrous bands and adhesions is fully considered elsewhere (See Intestinal Obstruction). Chronic Nodular Proliferative Peritonitis.—Pathologists and clinicians are familiar with a form of productive chronic peritonitis with nodular growths of the peritoneum and thickening, which so closely re- semble tubercle, as to be differentiated intra vitam (at the time of oper- ation) with the greatest difficulty. Welch calls attention to such cases in his section on the pathology of peritonitis in Flint’s “Practice of Medi- cine,” also in his discussion of Nicholl’s paper. Such cases are undoubt- edly at times included among the tuberculous, and are favorably influenced by surgical interference. Fitz and Wood also mention such possibility. The thickening and agglutination in these cases may lead to tumor forma- tion, either single or multiple; the viscera are covered with tense and thick peritoneum; circulatory embarrassment and ascites, at times obstruction, cause of death. I have found the productive (proliferative) peritonitis with alcoholic cirrhosis. In children I have occasionally seen chronic nodular non-tuberulous peritonitis with ascites and chronic invalidism. Some of these cases yield after operation; a few have made satisfactory recoveries without. Most of these children recover. General Conclusions.—Chronic peritonitis may complicate malignant and echinococcus involvement of the peritoneum when hemorrhagic ascites is likely. Whether “hemorrhagic peritonitis” is ever prinlary is ques- tionable. References Fitz & Wood. Practice of medicine. Philadelphia, 1897. Nicholls. J. Am. Med. ylss., March 14,1903, vol. xl, p. 701.

New Growths of the Peritoneum I have never in practice seen a case of primary cancer of the peri- toneum. Neoplasms (malignant) of the peritoneum are practically always secondary. Fatty deposits {lipoma), fibroma, and neurofibroma are occasional benign growths which do not materially interfere with the patients’ comfort as a rule, and are operable if large and troublesome. Innocent cysts and echinococcus of the peritoneum offer a good prog- nosis (See Echinococcus Disease). Aschoff calls attention to a diffuse endothelial degeneration of the peri- 664 DISEASES OF THE DIGESTIVE APPARATUS toneum which he considers primary and malignant (endothelioma). The prognosis is bad. The secondary carcinomata, usually multiple and disseminated, are found with stomach, gall-bladder, bile passage, pancreatic, intestinal (rectal often), ovarian, uterine, and renal (hypernephroma) growths. The mesenteric glands are involved; ascites is prominent—usually bloody —and after varying periods with characteristic facies and marasmus, death follows. References Aschoff. Path. Anatomic.

Jaundice (Icterus) Surcharged fluids and tissues of the body with bile coloring matter cause a yellowish coloration of the skin, mucous membranes, and con- junctivae, easily recognized and known as jaundice. Jaundice is never a disease per se; it is always a symptom and is due to obstruction of the flow of bile, which may be either complete or in- complete, in almost all cases. (a) Hepatogenous jaundice is always obstructive and is due to the resorption of bile manufactured in the liver which fails to escape from that organ, wholly or in part. (b) Hematogenous or hemo-hepatogenous jaundice is due to the change of hemaglobin into hematoidin, identical with bilirubin. In these cases there is rapid destruction of large numbers of red blood corpuscles— hemolysis, causing hemolytic jaundice; the hemoglobin is converted into bilirubin in the liver in most instances. Recent experimentation tends to prove the possibility of such conversion in the blood stream. (a) Hepatogenous Jaundice (Obstructive Jaundice) Causes.—The larger number of cases are due to mechanical obstruction in which there is reabsorption of bile which cannot escape into the intes- tine through the common duct. The most frequent causes of obstructive jaundice are (1) catarrhal inflammation of the duodenum and common duct with consecutive closure at the opening of the ampulla of Vater (catarrhal jaundice). Among the other causes of mechanical obstruc- DISEASES 0? THE LIVER 665 tion leading to jaundice are (2) the impaction of gall-stones in either the hepatic or common ducts; (3) stricture of the common duct, complete or incomplete, due to either ulcerative or inflammatory disease; (4) pressure of growths within the intestine or ducts causing sufficient obstruction to prevent the onward flow of bile; (5) extra-hepatic pressure from tumors of the liver itself or growths in the surrounding organs including cancer of the stomach or pancreas, or both at the same time, kidney growths, malig- nant disease of the omentum, glandular enlargements in the portal fissure of the liver, enlargement, either benign or malignant of the gall-bladder, mobile kidney, abdominal aneurism, either aortic or celiac, perihepatitis or any pressure from whatever cause which is sufficient to obstruct the free flow of bile. Bile is normally secreted at very low pressure; relatively insignificant increase of this pressure makes absorption of bile pigment into the blood easy and jaundice results. Catarrhal Jaundice (Gastroduodenocholangitis).—In consid- ering the diseases of the stomach we mention j aundice as one of the symp- toms of catarrhal gastro-duodenitis. In most cases in which jaundice develops there is more or less cholangitis, the larger ducts are involved by extension from the duodenum. The majority of these cases are found in young subjects in whom the jaundice follows error of diet, and a short period of gastro-intestinal symptoms. The features are characteristic of obstruction and include besides the yellow-tinged skin, discoloration of the internal organs and secretions, the conjunctivae and mucous membranes, with a slow pulse and respiration, subnormal temperature, clay colored stools and constipation; bile laden urine, pruritus; in obstinate and severe cases petechiae and cerebral symptoms. Simple uncomplicated catarrhal jaundice or gastroduodenocholangitis is usually a self-limited process which runs its course in from a few days to several months. In but few cases does jaundice persist beyond three or four weeks, but it may happen that the obstruction remains and continues the symptom beyond the average time. Such cases are associated with more or less stomach and intestinal symptoms and loss of weight with weakness. Convalescence is slow, but complete restoration to health is the rule. Influencing Factors Urine.—The urine offers evidences of value for prognosis. With ob- structive jaundice scanty and high colored urine is evidence of an active process; with increase of urine and the usual change to a lighter color from day to day, the prognosis for prompt recovery is good. The persistence of jaundice (usually fading) after the urine has cleared, is not unfavorable. Leucin and tyrosin are always unfavorable, they indicate grave and de- structive disease. 666 DISEASES OF THE DIGESTIVE APPARATUS Indicanuria is not unfavorable. Casts and albuminuria are frequent, and with the positive diagnosis of catarrhal obstruction—uncomplicated—- do not as a rule influence prognosis unfavorably. Transitory glucosuria in catarrhal jaundice is frequent and of no great significance. Feces The feces when “clay colored” prove the absence of bile from the intestine. The return of normal color is coincident with the removal of the obstruction. When jaundice is due to congestion of the liver secondary to disease of the mitral valve or to infections, as pneumonia or typhoid fever, the prognosis depends almost entirely upon the gravity of the primary disease. The infections and organic diseases in which jaundice may be a prominent symptom are separately considered. The presence of jaundice with any infection proves extension to the liver or bile passages and is of great prognostic significance. Jaundice with puerperal eclampsia is almost always fatal. With malarial infection (See Section I) it is significant but not always grave; with relapsing fever it is ominous; following or associated with acute abdominal lesions as appendicitis—it is unfavorable in 55 per cent of cases (Reichel). In a relatively large number of cases swelling spreads from the small intestine (duodenum) to the head of the pancreas sufficient to obstruct the common bile duct; the j aundice disappears as the pressure is relieved. In a few cases the infection causes chronic catarrhal jaundice; the bile passages, including the gall-bladder, are involved. Free drainage may be necessary to effect a complete cure. Deep jaundice, with or without cerebral symptoms, severe itching and petechiae are symptoms of the more severe types of the disease and in diagnosis should lead to the suspicion and differentiation of malignancy or other organic change. It is not impossible, however, to find these symp- toms in uncomplicated and severe catarrhal jaundice which recovers after a varying period and slow convalescence. Jaundice with marked liver insufficiency and evidences of toxemia. including marked nervous manifestations (delirium, somnolence, and deep coma) and hemorrhagic diathesis offers an unfavorable forecast; cholemia is the paramount factor in this syndrome. Nervous symptoms and jaundice usually indicate some grave underlying condition. There are cases of infectious jaundice with meningeal symptoms during a few days, with final full recovery wfithout disagreeable or persisting sequelae (Guillian and Richet). Rolleston has called attention to the similarity of these cases to epidemic cerebrospinal meningitis. Slow pulse with lowered arterial tension, subnormal temperature, 667 DISEASES OF THE LIVER slight albuminuria, yellow vision and slightly enlarged liver, or palpable gall-bladder, are not unfavorable in the absence of complications. Un- changing jaundice with loss of flesh and evidences of increasing weak- ness, whatever the initial symptoms, justify the conclusion that the ob- struction is likely to be of malignant or organic nature and demands thorough differentiation before prognosis is given. With cancer of the liver, jaundice once present persists and is not modified by any treatment. It only rarely happens that catarrhal jaundice complicates malignant diseases of the liver or pancreas; it is safe to cling to the rule that with malignancy the jaundice is persistent and deepens as the primary disease advances. I elsewhere consider the infectious type of jaundice known as Weil’s disease (See Section I). The occurrence of epidemic catarrhal jaundice is possible. Large numbers may be infected within a limited area at the same time; the prognosis of such infection is almost uniformly good; recovery follows in from seven to ten days in average cases. The jaundice associated with impacted gall-stone, either in the hepatic or common ducts, usually offers a good prognosis. In the majority of cases the obstruction is overcome either by nature’s process or by surgical interference. There is under such conditions, always danger of ulcera- tion, infection and suppuration; these complications are elsewhere con- sidered (See Gall-stones). Jaundice due to organic stricture of the common duct, complete or incomplete, following ulceration or inflammatory disease, pressure of growths within the intestines or ducts, can only be overcome by surgical interference unless of specific origin. Tumors of the liver itself, or growths in the surrounding organs including cancer of the stomach or pancreas, or both, and pressure from other sources already mentioned as causes of jaundice, only offer a favor- able prognosis when the growth is removable. The larger number of these conditions are not operable. Chronic jaundice may lead to multiple xanthoma (xanthelasma or vitilligoidea). In these cases the cause is not removable. Xanthoma may occur without jaundice. Xanthoma is evidence of chronicity and non-malignancy as a rule. Chauffard considers xanthoma due to excess of cholesterin in the blood. Chronic jaundice offers a grave prognosis. Surgical interference is not well borne. Hemorrhage is likely to occur and is not easily con- trolled. In chronic jaundice the functional activity of the kidney is an important factor; when sustained, the prognosis is thereby improved. Deep jaundice, also chronic, known as black jaundice, due to the presence of biliverdin is usually of malignant origin. In occasional cases leukoderma complicates chronic jaundice due to carcinoma (Warthin 668 DISEASES OF THE DIGESTIVE APPARATUS and Rolleston). Deep jaundice persisting from any cause is always ominous. (6) Hemolytic Jaundice—Toxic Jaundice (Hemo-hepatogenous Jaundice) It is now assumed that all forms of jaundice whether “obstructive” or “non-obstructive” as the older writers characterized them, are in truth hepatogenous. It has been abundantly demonstrated that the formation of bile pigment from the blood coloring matter of destroyed (fragmented) corpuscles outside the liver is usually limited to the liver cells, and accord- ing to most authorities does not take place in any other organ of the body; hence all forms of hemolytic jaundice are in reality hemo-hepatogenous (Moleschott, Stern, Minkowski, JSTaunyn and Stadelman). Hemolytic jaundice according to Eppinger is obstructive, because with the destruction of the red blood corpuscles there is an excessive amount of hemoglobin which in the end provides for increase of bili- rubin ; there is plugging of the smallest bile ducts and change in the epithelial cells with increased viscosity of the bile. Thrombi in the bile passages and in the capillaries of the liver are common. The intrahepatic bile stasis and rupture of intralobular biliary capillaries, with entrance of bile through the lymphatics, are the changes which follow hemolysis which leads to jaundice. Ogata has demonstrated the possibility of jaundice before the rupture of the intralobular capillaries, and he believes that it is possible to con- vert hemoglobin into bile coloring matter in the blood current or in the spleen; this view has not been generally accepted, though Whipple and Hooper have experimentally demonstrated the rapid transformation of hemoglobin into bilirubin in the blood current outside the liver. Ep- pinger claims to have demonstrated the production of lymphatic tissue at the peripheral end of the common duct in these cases of hemolytic jaundice, which prevents the free exit of bile. It is exceedingly difficult to offer positive evidence which explains the method or seat of blood corpuscle destruction. It has been estab- lished by Chauffard (1907) that the red blood corpuscle undergoes hemol- ysis in an abnormal manner when exposed to hypotonic saline solution; “normally hemolysis of the red blood corpuscle begins in 0.42 per cent HaCl solution and is complete in 0.3 per cent”; in hemolytic jaundice “it begins at 0.6 per cent and is complete at 0.42” (Rolleston). This fragility of the blood corpuscles is characteristic of hemolytic jaundice when a disease sui generis, and is not present with hemolysis of pernicious anemia nor the intoxications including lead poisoning. The influence of the spleen on hemolytic jaundice has received care- ful consideration in connection with splenectomy. It has been demon- DISEASES OF THE LIVER 669 strated that removal of the spleen in Banti’s disease and in the familial types of jaundice has overcome all symptoms with restoration of normal blood conditions (Kahn, McPhedren, Fletcher and Harold Orr). Hemo-hepatogenous jaundice may be a symptom of: 1. Infectious disease 2. Poisons and drugs 3. Cerebral disturbance 4. Sudden hemolysis, non-infectious or toxic 5. Splenomegaly. Causes of Hemo-hepatogenous Jaundice.—1. Infectious Disease.— The prognosis of jaundice of hemolytic origin with the infections is always exceedingly grave, for it is idicative of malignancy. The infections which hemolytic jaundice may accompany are yellow fever, typhoid, typhus, malarial, relapsing fevers, septicemia, pyemia, scarlet fever, pneumonia, Weil’s disease, and acute yellow atrophy of the liver. 2. Poisons and Drugs.—These include snake bites—exceedingly grave; phosphorous antimony and other mineral poisons, chloroform and ether, potassium chlorate, coal tar products, chloral, santonin, male fern, toadstools, copper sulphate, carbolic acid, pyrogallic acid and ptomain poisoning. The prognosis of these poisonings varies in the individual cases depending upon prompt detection of the poison and its treatment, the size of the dose, the resistance of the patient and many associated factors, each requiring separate consideration. 3. Cerebral Disturbances.—In the reduced and predisposed, sudden mental emotion or cerebral injury may be promptly associated with hemolysis and jaundice. The prognosis depends entirely upon the sever- ity of the brain lesion when this exists, and the constitutional disturbance; with mental emotion as a cause, the prognosis is usually good when uncomplicated. 4. Sudden Hem,olysis (Non-infectious or Non-toxic).—There are cases in which after periodic hemoglobinuria following exposure to cold, jaundice develops. When without nephritis, usually tubular, or the hemorrhagic diathesis, the outcome is favorable. The majority of these hemaglobinurias are due to existing, often latent nephritis, and it is not unusual to find hemolysis recurring after each exposure, until finally the symptoms of chronic nephritis are fully developed and death results from the usual causes which end the lives of nephritics. Jaundice following transfusion of blood is of no great prognostic value; the outcome will always depend upon the nature of the disease demanding the added blood elements. 5. Splenomegaly.—Splenomegaly with hemolytic jaundice include familial and hereditary types, and according to Rolleston the chronic infective jaundice of Hay era. The general features of obstructive jaun- 670 DISEASES OF THE DIGESTIVE APPARATUS dice are missing; there is absence of bile from the urine (acholuria) and the feces are normal colored. Rolleston insists that the familial types of jaundice are an exception to the rule which insists on obstruction as the cause of all jaundice, for the evidence, he holds, is conclusive, which proves the production of bilirubin in the blood current. The fragility of the red blood corpuscles as shown by hypotonic salt solutions is char- acteristic. Chronic splenomegalic hemolytic jaundice may be either hereditary, congenital or familial, or in occasional cases it may prove to be acquired (Rolleston). Benjamin and Sulka have reported family jaundice which appeared after birth in one generation and congenital in subsequent generations. The disease may be hereditary and congenital or hereditary without being congenital. In occasional cases there is no enlargement of the spleen. The acquired hemolytic jaundice may follow infection; it is usually syphilitic. This represents the type described by Hayem who unhesi- tatingly declares in favor of the specific origin of the disease in spite of repeated negative IVassermann reactions. The prognosis of the acquired or Hayem infections type—usually specific—is favorable. The prognosis of the congenital, hereditary and familial type, is not unfavorable for life; these subjects may live to old age without subjective complaints though they are without resistance to disease or traumatism and they never lose their jaundice. (c) Hereditary Splenomegalic Jaundice Jaundice in the newly horn may be either (1) physiologic, (2) in- fectious, (3) of the grave familial type, (4) obstructive due to organic lesions in the ducts or liver. 1. Physiologic Icterus.—Physiologic icterus, or the usual icterus neonatorum, also known as yellow gum, is found in the majority of babes soon after birth; it is hemo-hepatogenous and offers an excellent prog- nosis, for in a few (2 to 3) days without annoying complications the skin clears and all evidences of icterus disappear. From 40 to 85 per cent of all infants become jaundiced during the first, four days of life. At the Sloane Maternity Hospital in Hew York City, 300 of 900 births showed jaundice; 88 were intense, and 212 mild (Holt). Stevens made a collective investigation of 2,086 children of which 1,212 were icteroid—58.1 per cent. Jorak in 248 newly born babies found icterus neonatorum in 80 per cent. The important point to decide in offering the prognosis of icterus of the new born babe is whether the process is id) Icterus neonatorum DISEASES OF THE LIVER 671 physiologic or infectious, and in occasional cases two or more days may elapse before differentiation is possible. 2. Infectious Icterus neonatorum.—Infectious icterus neona- torum is rarely of the catarrhal variety or what Rolleston has character- ized as “mild infectious jaundice.” Skormin found but three recorded sases. Thompson says that new born infants may be very ill with catar- rhal jaundice and yet they recover as a rule. The severe infectious jaundice of the new born is usually of umbilical origin—suppurative umbilical phlebitis. The complication is prevent- able, is often conveyed from the mother—when it is likely to be strepto- coccic and has a very high mortality. Unfavorable features are high fever, rapid pulse, evidences of suppu- ration, gastro-intestinal symptoms, cyanosis, great unrest, and infection of several organs. There are at long intervals epidemic forms of infec- tious jaundice among the new born in which there are marked hemor- rhagic symptoms. In these epidemics almost all die. Winckel reports 24 cases with 23 deaths. In most severe and malignant jaundice of the new born the infection is associated with the symptoms of septicemia and purpura, multiple embolic infarct, and acute fatty degeneration of the liver and other organs (Buhl's disease, also Winckel’s disease). 3. Grave Familial Type of Icterus neonatorum.—Grave fa- milial type of icterus neonatorum, attacks successive infants of the same mother—all of these die. I had four consecutive cases, children of one mother all of whom died within four days of birth. The first child born to this mother was perfectly well, never jaundiced and grew to man- hood. There was no history of similar disease in the ancestors of these parents nor among the brothers or sisters. Arkwright reports a series of 14 cases in one family—the mother of these infants had jaundice when four years of age. Glaister reports that all of Morgagni’s children, 15 consecutive births, had icterus neonatorum. 4. Obstructive Icterus neonatorum Due to Organic Lesions in the Ducts or Liver.—Congenital obliteration of the bile ducts has been fully described by John Thomson who reported 50 cases; and How- ard and Wolbach gathered the reports of 76 post mortems. Rolleston offers two explanations: (I) “that there is in the first place a develop- mental aplasia or a narrowdng of the duct which gives rise by obstruction to cirrhosis; (II) that there is first a mixed cirrhosis of the liver which gives rise to a descending obliterative cholangitis.” In practically all cases examined microscopically by Thomson and Rolleston, cirrhosis ivcis present. Rolleston says: “To sum up it is reason- able to believe that the disease is primarily started by poisons derived from the mother and conveyed to the liver of the fetus, and that a mixed cirrhosis and cholangitis are thus set up. The cholangitis accounts for DISEASES OF THE DIGESTIVE APPARATUS 672 the jaundice and by descending to the larger extrahepatic bile-ducts, induces an obliterative cholangitis analogous to obliterating appendi- citis.” In the unfavorable cases the occlusion of the ducts is absent, as death takes place early in life from congenital cirrhosis—if such cases live occlusion finally results. Death may result during the first week of life from either umbilical or other hemorrhage. Of Thomson’s 49 cases, 30 lived beyond the first month and of these 16 lived more than four months; 2 lived “into the eighth month.” Laveson collected 62 cases; of these hut three lived 8 months, and of these 1 lived 11 months. Infection and hemorrhage claim most infants. Only the gloomiest prognosis is justified. There are, as Treves and Ashley have demon- strated, cases with only limited changes which remain latent for years, finally there is gradual cicatricial inflammatory occlusion. Hereditary syphilis of the liver and hile passages is a cause of icterus neonatorum. Many of these children die; a large proportion recover if radical treatment is promptly instituted. It rarely happens that gall- stones cause jaundice in the new horn (See Gall-stones). References Arkwright. Edinburgh Med. J., 1902, New Ser., xii, p. 156. Benjamin & Sulka. Berl. klin.

Acute Yellow Atrophy of the Liver Malignant Jaundice General Statements.—Acute yellow atrophy of the liver is an infec- tious disease of adult life, occurring oftener in women than in men; the relative frequency with which it attacks pregnant women is surprising. It is characterized by atrophy and degeneration of the liver cells, prob- ably autolytic (Flexner) and is usually fatal. Legg found that Baillon (Ballonius) reported a case in 1616; Bright in 1836 described and illustrated the disease, and in 184-2 Rokitansky gave it its present name. Acute atrophy of the liver is a very rare disease; in an active hos- pital experience I have during the past thirty years seen hut 2 cases, and in private practice during an equal time I do not recall more than 3 cases. Among my last 6,300 internal diseases tabulated in private practice I failed to find a single case of malignant jaundice. In 21,682 medical cases at the Johns Hopkins Hospital, Thayer reports but 3 cases. Rolleston has seen 11 cases post mortem in twenty-seven years. Symptoms.—With the rapid destruction—degeneration of liver cells —-the evidences of overpowering toxemia are prominent early, and the symptoms referable to the nervous system—delirium and coma, in young subjects convulsions—with jaundice, are suggestive with the physical signs of decreasing liver dullness of the gravity and nature of the process. There are cases in children, though these are exceedingly rare. The usual age is between twenty and forty years—my last case was six- teen years of age. The symptoms which brand the disease and which make prognosis possible before the end of the first twenty-four hours in the majority of cases, are early obstinate vomiting, greenish skin and conjunctiva, hemor- rhagic symptoms—hematemesis, melena, petechiae—followed by the 674 DISEASES OE THE DIGESTIVE APPARATUS prompt invasion of the sensorium and rapid wasting, weak heart, and urinary changes, including leucin, tyrosin and albuminuria with scanty urine, tinged bile, and in some, almost complete suppression. Some enlargement of the spleen is the rule; the heart and kidneys show the degenerative changes of malignant infection. Origin.—The atrophic and degenerative congenital liver changes are probably without exception of luetic origin. The acute syphilitic liver changes are considered elsewhere (See Syphilis of the Liver, Section I). Weber in 1909 found 53 cases of acute yellow atrophy of syphilitic origin in medical literature, and Fischer reports 50 collected cases of which four-fifths were females. These cases are not true cases of acute yellow atrophy, they may run a long course and occasionally recover and should he classified as icterus gravis. Unquestionably preceding infection and worry or mental emotion, as well as alcoholic excess, invite acute liver atrophy. Ballin and Torek both report fatal cases of the disease after surgical operation and anesthesia. Torek reports its occurrence after the use of anesthol, a combination of chloroform, ethyl chlorid and ether. Fatal acute atrophy of the liver may develop after chloroform anes- thesia ; evidences of degeneration are not immediate. These cases are exceedingly puzzling. One such with complete yellow atrophy Fischer of Frankfurt demonstrated in 1914 which followed an operation for appendicitis in a boy. Brackel’s experiences are also worthy of study in this connection (See References). Atrophy, acute and fatal, may develop in occasional cases of cirrhosis of the liver, catarrhal jaundice, hyperemia and gall-stones. The inci- dence is exceedingly rare. Acute phosphorous poisoning is not identical with acute yellow atrophy though the subjective features are strikingly similar. Pathologically the differences are positive. With phosphorous poisoning the fat in the liver reaches 30 per cent and more, the size of the liver is increased; with acute atrophy there is but five per cent of fat in the organ and atrophy is its fate (Rolleston). The blood shows abnormal concentration with a high red count and moderate leukocytosis. Grawitz reports 5,150,000 red blood corpuscles and 16,000 leukocytes, while at the Massachusetts General Hospital the count averaged 5,520,000 reds and 12,000 whites with 60 per cent hemoglobin. Blood cultures have thus far failed to enlighten the clinician. Libman and White report negative culture, and Vincent found the colon bacillus in his case. There is marked acidosis and fixation of ammonia by the organic acids, the liver being unable to transform the ammonia into urea. Urea is reduced and the percentage of ammonia is increased in the urine. The total nitrogen loss is increased because of the autolysis of the liver cells, and the ammonia accounts for at least twenty per cent of the DISEASES OF THE LIVER 675 total nitrogen, whereas normally it accounts for only five per cent. I have not seen the cases of prolonged and subacute liver atrophy described by some writers (MacDonald and Milne). These are likely to be due to cirrhosis with enormous destruction of liver cells or to subacute hepatitis, and ought not to be considered acute yellow atrophy. Forecast.—Cases with positive symptoms lifting the diagnosis above doubt offer an unfavorable forecast. My experience does not include a single recovery. I agree with Rolleston who says: “Some doubt would always arise as to the nature of cases that recover completely.” The regenerative power of the liver which is certainly paramount when there is a remnant of liver cells to proliferate, may in rare instances make recovery possible. In these cases there is a compensatory hyperplasia which may save life, but recurrence and advancing degeneration may ultimately lead to death. The prognosis, bad at all ages,, is slightly better in children than in adults. Pregnant women offer only the gloomiest prognosis. Once the kidney function is seriously disturbed—and this is a part of the toxic and degenerative process—in most cases the outlook becomes correspond- ingly bad. Legg’s list includes 28 cases, 4 reported recoveries; and Wirsing collected 15 non-syphilitic cases of recovery. Duration.—The duration of the average case of yellow atrophy is less than four days. Some live into the second week; only a few become subacute. The chronic course casts doubt on the diagnosis as already suggested. Ballin. Annals of Surgery, 1903, xxxvii. Bracket. Samml. klin.

Circulatory Disturbances of the Liver (a) Congestion of the Liver (.Hyperemia) In all forms of congestion of the liver the prognosis must be based on its cause. i. Active Hyperemia Active hyperemia is purely physiological during the process of diges- tion, and is pathological in such conditions as cause increased supply of blood to the liver, either as the result of vascular paralysis or true ple- thora, i. e., polycythemia. The prognosis of this condition as it occurs with the various infections (diphtheria, malaria, typhoid and typhus fever, etc.) has been separately considered. There are in all probability a limited number of active hyperemias arising from faulty diet and improper living in which judicious and temperate habits with proper exercise lead to prompt recovery without remnant of organic change. ii. Passive Hyperemia Passive hyperemia is always a secondary process; it is rarely recog- nized during its incipiency, but in the advanced stage presents charac- teristic changes which prove the obstruction in the portal system. The leading primary lesions are cardiac and pulmonary. There are other factors which may lead to chronic congestion of the liver, including aneurismal pressure, growths, which cause pressure on the inferior vena cava, occlusion of the hepatic veins, obstruction of the portal vein, or thrombosis. Rolleston includes malignant growths or hyatid cysts, pleural and pericardial effusion, pericardial and mediastinal adhesions.' The prognosis of hyperemia in these conditions naturally depends on the ability to remove the cause. The cardiac lesions which cause secondary hyperemia of the liver are usually valvular, in which compensation is faulty. Mitral obstruction and regurgitation and diseased myocardium are the leading lesions which cause backward pressure, with consecutive tricuspid insufficiency and chronic liver engorgement. Tricuspid stenosis may cause marked secondary hyperemia; it almost always follows mitral obstruction. With mitral stenosis there is, after a varying period, per- sistent venous engorgement, with characteristic enlargement of the liver which persists and leads to consecutive organic changes. Mitral stenosis is probably the most powerful cause of the “cardiac liver.” The acute infections may also cause liver congestion depending upon DISEASES OF THE LIVER 677 myocardial degeneration and sudden dilatation. The pulmonary lesions which cause chronic hyperemia of the liver are chronic emphysema and asthma, chronic bronchitis, interstitial pneumonia, the pneumonokoni- oses, and occasionally pulmonary tuberculosis. The damage to the liver depends entirely upon the degree and duration of the venous stasis. Early, the liver is enlarged and the capsule tense; as the condition re- mains and becomes chronic there is more or less productive change, final atrophy and shrinking, with the usual symptoms of portal obstruction. With heart lesions, the hyperemia may always be considered to he per- manent, and if the patient lives, the secondary changes in liver tissue are sure to follow. The prognosis of cardiac and pulmonary conditions is unquestionably unfavorably influenced by the secondary changes in the liver, hut it depends more upon the ability of the heart to compensate for the primary anomaly than upon any other factor. Secondary hyperemia with persistent gastro-intestinal symptoms, which are proof of engorgement of the entire portal system, offers an unfavorable prognosis for life; with cardiac dyspnea and associated dropsies there is usually congested kidney and evidences of overpowering toxemia and weakness. Ascites is an unfavorable symptom, though in some cases, under treatment, the tone of the heart may be sufficiently improved to prolong the lives of these patients. With mitral obstruction and insufficiency it is not at all uncommon to follow patients during many years who live in comparative comfort with chronic painless enlargement of the liver. Persisting jaundice with passive congestion of the liver is always unfavorable, and is found in the most severe cases. The deeper the coloring the more threatening is the complication. Jaundice with cya- nosis is always unfavorable. The urine gives valuable data for prognosis in all primary heart, lung, and other conditions associated with congested liver. Concentrated, scanty, albuminous, bile-laden urine with casts or with- out, urobilinuria, acidosis, leucin and tyrosin, is always ominous and justifies the conclusion that death is imminent in most cases. W ith the gradual increase of hyperemia and consecutive organic changes in the fiver substance, a degree of tolerance may be established with regenerative and compensatory changes sufficient to prolong life during indefinite periods until the right heart finally yields. When the organic changes are sufficiently advanced in the liver as to cause marked cirrhosis and atrophy, conditions exist which, according to Hunter, amay be said to have an independent existence, and such advanced changes make the prognosis exceedingly grave. It is often surprising how many years patients with chronic heart and lung lesions (emphysema, asthma, chronic bronchitis) live without change in the size of the enlarged and engorged liver. With enlarged and pulsating liver 678 DISEASES OF TIIE DIGESTIVE APPARATUS associated with tricuspid insufficiency, improvement of secondary symp- toms is not to he expected. The pulsation remains to the end (Mackenzie). Infection (pneumonia, pleurisy, malignant endocarditis) is a frequent cause of death. In a number of my cases the infection has followed along the bile passages from the intestine; icterus gravis has resulted, and death has promptly followed. The association of purpuric or hemorrhagic symptoms with or with- out jaundice, delirium, coma, convulsions, the typhoid state with increas- ing myocardial weakness, are among the most unfavorable features.

(6) Diseases of the Portal Vein Pylephlebitis (Pylethrombosis, Adhesive Pylephlebitis; when suppurative: Suppurative Pylephlebitis, Portal Pyemia, Multiple Abscesses of the Liver) Pylephlebitis is an inflammation of tlie wall of the portal vein or one or more of its branches with thrombosis or final suppuration. The majority of all cases are associated with primary systemic infection in which the blood shows characteristic changes. Thrombosis of the portal vein may follow long continued inflamma- tion of the vein, change in its coats, calcification, phlebitis, or syphilitic deposit. Thrombosis may be due to extension of inflammation, i. e., infection from neighboring or distant organs. Thus with ulcer of the stomach or intestine, cancer of the stomach or pancreas, cholecystitis— with or without gall-stone—cholangitis, liver abscess, pancreatic inflam- mation, appendicitis, pelvic abscess, puerperal or pneumococcus infection, diphtheria, distant or near thrombosis, there may be extension to the portal vein. Following surgical operation for infectious processes, portal thrombosis is a relatively frequent complication. If the causes of all portal thromboses were cautiously tabulated, the seat of the primary disease in the individual case would be found in one of many organs, and with innumerable infections. There is scarcely an organ from which DISEASES OF THE LIVER 679 portal infection may not spread. Portal thrombosis is frequent with splenic infarct and other lesions of the spleen, including abscess, trauma, infection and perisplenitis. With many grave forms, the spleen is mark- edly enlarged. The thrombosis of marasmus is of infectious origin, and always sec- ondary. Herringliam says: “To sum up, it may therefore be stated that the great majority of the cases depend upon local conditions; that, whether of local or general origin, infection is the most probable cause in all but those in which the vein is invaded by new growth, or by mul- tiple adenoma, and is not excluded even in these; and that in a few cases no explanation can be given.” The underlying infection is usually so malignant or serious as to threaten life; the added thrombosis increases the dangers, making recov- ery exceedingly rare. With thrombosis and liver cirrhosis the course is often subacute, the duration varying from several weeks to as many months. The same course is found with malignant disease of the liver. Cases in which there are peritoneal adhesions may persist during a num- ber of months. A number of recoveries have been reported. In some of these reported by Lyons, Osier and Rogers, it is difficult to controvert the diagnosis, but a strong element of doubt is justified and I am fully in accord with Herringham when he insists that “where diagnosis is so certain, no case of recovery can be admitted which is not proved by sub- sequent dissection.” The prognosis, however, is better than in pylephle- bitis. Compensation of the circulation is possible in cases in which portal thrombosis is limited and progresses gradually. Suppurative Pylephlebitis—Portal Pyemia—Multiple Abscess of the Liver This condition, always infectious, is fully considered in this section with Abscess of the Liver, to which the reader is referred. (c) Diseases of the Hepatic Vein Complete occlusion of the hepatic vein is exceedingly rare; its only interest is pathologic, for it cannot be diagnosticated intra vitam. The symptoms of hepatic occlusion, thrombosis, or phlebitis, are rather indefi- nite but usually include pain, abdominal and epigastric, gastro-intestinal symptoms, vomiting; in the subacute cases, ascites with enlargement of the liver, which continues more or less tender; jaundice is ndt usual. All are supposed to die. Thrombosis of the hepatic vein may be due to new growths of the liver, cirrhosis, stricture, or it may be a part of a widespread thrombosis, including portal thrombosis. Growths by pressure (carcinoma, hydatids, gummata) causing stasis lead to thrombosis. Rolleston includes oblitera- 680 DISEASES OF THE DIGESTIVE APPARATUS tive endophlebitis of the hepatic veins as a cause. Embolism of the hepatic vein is rare. Welch reported fragments of new growth in the hepatic vein in cases of primary carcinoma of the thyroid and abdom- inal organs. (d) Diseases of the Hepatic Artery The anomalies of the hepatic artery include: Aneurism Embolism Thrornbosis Arteriosclerosis and according to Rolleston: Enlargement of the vessel. Aneurism.—Rolland reported (1907) 41 cases in medical literature of aneurism. The average age of Holland’s cases was 37 years, and the extremes were 83 and 14 years. The proportion of males to females was 3 to 1, and the average age in women was 10 years higher than in men— 45 to 35 years. Ulceration in the gall-bladder or bile ducts may erode the wall of the artery and cause aneurism; the rupture is usual into the biliary tract in such cases. Gall-stones are potent factors in causing these ulcerations. ISTaunyn and Schmidt have reported cases in which impacted gall-stones have finally opened into aneurism of the hepatic artery. Jaundice is usually a late symptom, and is due to pressure on the ducts. Ascites is not a symptom of hepatic aneurism. Aneurismal dilatation of the artery is always fatal; death is usually due to perforation. Perforation may take place into the peritoneum, the bile passages, the gall-bladder, the portal vein, or into the stomach, or (rarely) into the intestine or pancreas. Infection of the bile passages and pancreas is an occasional complication. Ross and Osier reported a case of infected aneurismal sac, multiple emboli, and many secondary liver abscesses. Fully formed hepatic aneurism is incurable; not all die from it directly, but most do. Rupture and perforation into the sur- rounding organs are the leading causes of death. Hans Kehr has suc- cessfully removed an aneurism after ligating the hepatic artery. Embolism.—Embolic infarcts may cause multiple abscesses. They are always fatal, are secondary to malignant endocarditis, carcinoma, sarcoma—the melanotic type particularly—and are occasionally present with tuberculosis. Thrombosis.—Thrombosis of the hepatic artery is considered a “pathological curiosity” (Rolleston). I have never met a case. Lance- reaux found a clot in an arteriosclerotic hepatic artery in a patient, aged 65, who had general atheroma and died of gangrene of the feet. Arteriosclerosis.—Arteriosclerosis of the hepatic artery is a part DISEASES OF THE LIVEK 681 of a widely disseminated process. Secondary atrophy of the liver results in some cases—fibrosis of the liver is not usual with hepatic arterio- sclerosis. Endarteritis obliterans may accompany cirrhosis of the liver; Kol- leston holds that endarteritis deformans is more frequent. Enlargement of the Hepatic Artery (Eolleston).—With carci- noma and other new growths the hepatic artery is at times enlarged; the same is occasionally true of advanced cirrhosis and chronic portal thrombosis. In all vascular lesions of the liver, both the underlying causes and the vessel changes are so grave and far-reaching as to make the forecast bad. The length of life in the individual case depends upon the nature of the primary lesion and the local changes caused by the altered vessels and disturbed circulation. References Herringham.

Cirrhosis of the Liver (a) Multilobular Cirrhosis (■Chronic Interstitial Hepatitis, Laennecs Cirrhosis) (b) Unilobular Cirrhosis {Hanot’s Cirrhosis) (c) Pericellular or Syphilitic Cirrhosis (d) Capsular Cirrhosis (.Perihepatitis) All forms of liver cirrhosis are characterized by connective tissue proliferation and changes in the liver substance. In all there is, in spite of destructive changes, marked tendency to regeneration of the liver cells. Another favorable factor is the fact that the connective tissue, contrary to the rule, holds capillary vessels which permit of the passage 682 DISEASES OF THE DIGESTIVE APPARATUS of blood to the intralobular veins by way of the hepatic artery, which (in alcoholic cirrhosis particularly) continues liver function, including bile formation. (a) Multilobular Cirrhosis (Laennecs Atrophic Cirrhosis, Portal Cirrhosis, Chronic Interstitial Hepatitis, Contracted Liver, Hobnailed Liver, Drunkard’s Liver, Alcoholic Cirrhosis) Factors Which Influence Prognosis.—Alcohol is unquestionably the most frequent poison which causes cirrhosis of the liver taken in the form of whiskey, gin, and brandy. Beer may cause mixed forms of cirrhosis, but it is less likely to produce the multilobular type of cirrhosis than are the stronger spirits. It is rare to find Laennec’s cirrhosis with- out the history of alcohol abuse; it is possible however—a fact of diag- nostic as well as prognostic value. The study of my material justifies the conclusion that the majority of atrophic cirrhoses were found with an alcoholic history. Whether the changes in the liver are primary or secondary, we cannot ignore the positive history of the habit and I cannot agree that there is danger of exaggerating the “importance of alcoholism” as a pathogenic factor. There are other factors besides alcohol which cause cirrhosis, and there are many ingested poisons, besides alcohol, as well as congenital and acquired factors which lower liver resistance and predispose the organ to degenerative and productive changes. The spleen is under suspicion as a poison-producing organ of trans- cendent importance in causing productive changes in the liver. The telling results which follow splenectomy in Banti’s disease in which there is co-existing cirrhosis of the liver, and the early enlargement of the spleen in some forms of hypertrophic biliary cirrhosis justify the strong suspicion and the hope that ultimately we may find that through the spleen the liver changes are invited or provoked, and that early splenec- tomy in cirrhosis may abort these. This entire question is still sub judice—no authoritative statement is justified. There are some facts connected with the spleen which are of importance and are positive. The spleen is enlarged in 80 per cent of all cases of portal cirrhosis of the liver (Klopstock). The spleen is small in the more rapidly pro- gressive cases, with profuse hematemesis, also with those in which ascites develops early. To some of these facts I again refer in considering individual symptoms. Faulty Diet.—There are unquestioned cirrhoses in which faulty diet and consequent dyspeptic conditions, long continued, are causative fac- tors. Ingested poisons by irritation, as well as those due to fermentation in the intestinal tract, may lead to “dyspeptic cirrhosis.” The early DISEASES OF THE LIVER 683 detection of such cases is by no means easy; the changes are insidious and are advanced before marked subjective or objective manifestations cause the patient to seek medical advice. Most of these cases run an exceedingly chronic course and are favorably influenced by rational treat- ment and proper living. Etiology.—The question of etiology of cirrhosis as it influences 'prognosis is still uncertain, but it is positive that there are many poisons which may cause liver changes parallel with cirrhosis. The lesions may be limited or widespread. There is a growing belief that cirrhosis of the liver in man is always of toxic origin. Rolleston’s conclusions in this connection are as follows: “Poisons may be absorbed either from the alimentary canal and reach the liver in a comparatively concentrated form, or they may travel to the liver by the hepatic artery and are then comparatively diluted. Ordinary cirrhosis in man is generally due to poisons traveling by the portal vein. Alcoholism is rather an antecedent condition than a true cause, and acts indirectly or in an accessory man- ner. The possibility that cirrhosis is definitely due to microorganisms must be faced; from analogy it is most probable, but at present it has not been certainly established. It is also highly probable that poisons, or perhaps microorganisms, reaching the liver by the hepatic artery, may give rise to cirrhotic changes.” “As a result of destruction of the hepatic cells and absorption of their proteins into the circulation, hepatic anti- bodies, or cytolvsins, are produced. These destroy the liver cells and thus a vicious circle is produced” (Fiesinger). The disease may be found during childhood, this is rare; it is most frequent during and after middle life, in the male oftener than the female. Mortality.—Hawkins’ statistics show that “the annual death rate from cirrhosis of the liver in England and Wales rose considerably from 1871- 1900, reaching 134.6 in the last year, but in the quinquenium, 1901-5, a fall of 121.2 occurred. In 1905 there were 4,008 deaths registered in England and Wales as due to this disease.” The mortality from cirrhosis of the liver in the rural districts of Hew York State, as shown by Hoffman’s statistics, is lower than in the cities of the State. “The rates have not been subject to a wide range, for the minimum rate per 100,000 of population in the cities of Hew York State was only 19.3 in 1909, while the maximum rate was 22.2 in 1907. The minimum rate for the rural territory was 10.1 in 1900 and the maximum rate was 15.1 in 1907. In 1909 the rural mortality from cirrhosis of the liver was 69.9 per cent of the urban.” Of 91 male white cases of cirrhosis of the liver admitted to the Johns Hopkins Hospital at Baltimore, 16 died in the hospital—17.6 per cent. During the same period (1902-1911) 16 white females were admitted with one death in the hospital—6.3 per cent. During the same period 15 colored males with cirrhosis were admitted with 2 deaths while in the 684 DISEASES OF THE DIGESTIVE APPARATUS hospital—13.3 per cent, and 4 females with no deaths. The total num- ber of white medical cases was 7,299 males, from 1892 to 1901, and 3,209 females, from 1902-1911, 8,213 males, and 4,186 females. Col- ored medical cases included 1,678 males from 1892-1901 and 442 females; from 1902-1911 there were 2,109 colored males and 650 females (Hoffman). The average age of individuals who die with the lesions of cirrhosis but without symptoms during life is according to Hilton Fagge “five years higher than of persons dying of the disease.” This fact is a strong argu- ment in favor of the success of the “compensatory processes.” Rolleston on the other hand says: “In my own figures there is very little difference between these two classes.” Rolleston’s statistics gathered from 78 cases dying from cirrhosis show an average of 48.3 years; whereas in 87 patients who died from independent causes but whose livers were cirrhotic, the average age was 49.1 years. In alcoholic women especially, death from cirrhosis is much earlier than in those cases in which there is no history of alcoholic excess. Natu- rally the prognosis of all portal cirrhosis depends upon the extent of the liver changes, including the destruction of the liver cells, the extent of connective tissue production, the changes in the capsule, the obliterative changes in the portal vein, and its branches, the secondary changes in the ducts, the amount of amyloid and fatty degeneration of the organ, the accompanying lesions in other organs—kidney, heart and blood vessels particularly—the habits of the patient and his resistance, besides the regenerative power and tolerance of the liver itself. Additional Prognostic Factors.—Latency.—It is often surprising to find how long after initial symptoms and positive physical signs the dis- ease may remain latent. The duration of these periods of latency depends upon compensation which results from the collateral circulation estab- lished between the branches of the portal veins and the systemic veins and the regeneration of the liver cells. I have followed cases which finally died of intercurrent disease or accident during many years, in which the cirrhosis was advanced as shown at post mortem, the patients having lived with but few or no symptom's of the liver lesions. Hanot and Gilbert believe that the compensatory changes during latency cause enlargement of the liver in the majority of cases. All agree that cirrhosis is oftener latent in men than in women. Rolleston does not believe that this is due to the greater frequency of the diseases in men than in women, “for the ratio of women to men is lower among the cases dying inde- pendently of cirrhosis than among the cases fatal from the direct effects of cirrhosis.” The latency of the disease is an important prognostic factor. If the diagnosis is made early, before the various processes are advanced and PISEASES OE THE LIVEK 685 the habits of the patient are controlled, without complication or toxemia, the chances for long periods of latency are exceedingly good; limited changes in the organ under such conditions may not materially interfere with the general health or length of life. Patients with advanced latent cirrhosis are subject to complications-— pneumococcus and tuberculous infections particularly—which often end their lives. Such subjects do not offer normal or average resistance to disease or trauma. Cirrhosis of the liver in the majority of cases, because of the tolerance of the organ and long periods of latency, often the care- lessness of the patient and faulty diagnosis, due to the prominence of gastric symptoms, is not diagnosticated, until the disease is far advanced and pernicious habits are thoroughly fastened. Lesions in Other Organs.—The lesions in other organs than the liver have an important bearing on prognosis. Cirrhosis of the liver is often associated with far-reaching changes in the digestive tract with organic lesions of the esophagus, stomach, intestines and pancreas, besides the spleen, already considered. Advanced pancreatitis is frequent; the fibrosis of the organ is often so advanced as to be out of proportion to the changes in the liver. Esophageal lesions include changes in the mucosa, epithelial thicken- ing, dilatation and varicose veins, and ulceration. The rupture of an esophageal varix or ulceration may cause profuse and threatening hem- orrhage. The stomach lesions include chronic gastritis (alcoholic) varicosities of the gastric veins at the cardia, continuous with the esophageal dilatation or separate. These may rupture or ulcerate and prove life-threatening. Single or multiple gastric ulcers are occasional complications. The multiple ulcers are usually superficial, the single gastric ulcer is not fre- quent. Intestinal lesions which are associated with cirrhosis include chronic enteritis with productive changes causing marked thickening of the mucosa and atrophic changes in the glandular structures. There is with these atrophic changes in the chronic cases diminution in the length of the intestinal tract. The venous system of the intestine is likely to be engorged and the rectal veins dilated with hemorrhoidal swellings. Rec- tal ulceration and bleeding‘ may prove depleting. Kidney lesions complicated the majority of our cases. In over 50 per cent of. all cases the kidney is enlarged. Milian and Bassnet in 89 fatal cases of cirrhosis found the kidneys normal in 19; in 53, or 59.5 per cent, they were healthy or more or less hypertrophied. Pitt’s sta- tistics show that when otherwise healthy, the kidneys were hypertrophied in 50 per cent of liver cirrhosis. Arteriosclerotic interstitial nephritis is present in at least one-fourth of all cases and with the general invasion of the arterial tree, and toxemia is serious. Sears and Lord in this series of 78 fatal cases of cirrhosis 686 DISEASES OF THE DIGESTIVE APPARATUS report chronic nephritis (interstitial or tubular) in 23—or 29.4 per cent, fatty change in 15, and lardaceous change in 2. Rolleston compiled 440 cases of cirrhosis of the liver from the statistics of Pitt, Kellynack, Yeld, Cheadle and his own, in which he found 110 “with distinct fibrosis of the kidneys (25 per cent).” Non-tuberculous Chronic Peritonitis.—Sears and Lord in their series of 78 cases found chronic peritonitis in 19 per cent. In most cases this peritonitis is mild and insignificant; indeed by causing agglutination of peritoneal layers or folds it may often prove salutary. Severe or advanced and threatening chronic peritonitis is comparatively rare with liver cir- rhosis. The peritoneum, according to Rolleston, may with ascites be irritated by the “toxic bodies or bacteria in the ascitic fluid”; . . . “and it is conceivable that occasionally they are both related to alcoholism.” Ascites with chronic peritonitis may require repeated tapping, and re- covery may at times follow. The prognosis following tapping without chronic peritonitis is less favorable than with it and death is more prompt. The latter cases rarely live to be tapped more than two or three times. Chronic peritonitis has complicated a few of my cases. In some of these ascites was an early symptom, in others late. From 8 to 10 per cent of all liver cirrhosis show tuberculous peritonitis. Nineteen per cent of Sears’ and Lord’s cases of cirrhosis had chronic peritonitis. Kellynack’s material included 121 cases of cirrhosis, of which 12 had active peritoneal tuberculosis. Only one-third of these failed to show tuberculous disease elsewhere in the body. Pulmonary Tuberculosis.—Cirrhosis of the liver predisposes to tuber- culosis and the lungs are the usual seat of disease. Not all cases of pulmonary tuberculosis associated with cirrhosis are active. There may be but few or no symptoms; the process may be latent during long periods. In a small number of .cases there is an acute and rapidly fatal course with all of the lesions and symptoms of miliary tuberculosis. Tuberculous lesions are found in the lungs of over 22 per cent of patients dying of liver cirrhosis as proved by the statistics obtained from 584 cases (Lancereaux, Kellynack, and Yeld). The addition of acute pulmonary peritoneal or intestinal tuberculosis is promptly fatal with fever, emaciation, and deep toxemia. Chronic tuhercxdosis with cirrhosis may cover a long history and if the latter is limited and the former not far advanced, under favorable conditions life may be materially pro- longed (See also separate symptoms, etc.). Arteriosclerosis, etc.—Syphilis, alcoholism and cirrhosis of the liver, coincident during middle life, naturally include arteriosclerosis. Prob- ably arteriosclerosis and liver cirrhosis bear but little relation to each other, and cirrhosis per se is not likely to produce arterial degeneration. Most cases of cirrhosis unless complicated with coincident nephritis and arteriosclerosis are without suggestive arterial hypertension. Mixed DISEASES OF THE LIVER 687 cases of alcoholic and syphilitic cirrhosis may include specific arteritis (
