Volume 5 — DISEASES OF THE NERVOUS SYSTEM. (continued 20)

²⁰ Ivresses anormales ou pathologiques of the French writers.

The termination of the paroxysm is as abrupt as its onset. Some abatement of its violence is quickly followed by signs of mental and bodily exhaustion; this deepens into profound sleep, which often lasts from twelve to twenty-four hours, and from which the patient awakes clear, tranquil, and as if nothing had happened, or dimly recollecting the occurrences that have passed as a hideous dream. In a small proportion of the cases the sleep deepens into coma which ends in death.

2. The Convulsive Form.—The analogy to the form just described is very close. Here, however, the morbid manifestations directly relate to the muscular system. The attack is commonly sudden, often abrupt. When prodromes occur, they are such as have been described as preceding the maniacal form—mental irritability, headache, præcordial distress, etc. The attack is thus described by Lentz: “The phenomena consist not in ordinary convulsions, but in convulsiform movements of remarkable disorder, only to be compared with the extraordinary convulsive movements of grave hysteria. We have happened to see several cases during the attack. These patients threw themselves to the ground, giving themselves up to the most irregular and disorderly contortions, rolling from side to side, throwing the body into the air, striking out with the legs and arms, kicking at random, biting at persons and things—now knocking the head against the floor, again rising for a moment, only to fall back and commence again the same contortions. Their movements are energetic and violent. There are madmen whom it is dangerous to approach by reason of the violence of their movements, but they are certainly much less dangerous than those suffering from the maniacal form of acute alcoholism, for their morbid motility has no tendency to take the shape of co-ordinated actions. It is movement wasted in pure loss. Their muscular energy is excessive; it is difficult to restrain them. To resume: the peculiarity of these movements is this, that they are not intentional, but that they are rather purely convulsiform, automatic.

“Another phenomenon of this form, one of its characteristic symptoms, is the state of intellectual enfeeblement which accompanies it. The loss of consciousness is complete, and were it not for the movement produced by the convulsions the patient would be plunged into a condition of profound coma. He has not the least knowledge of himself; not even delirium denotes intellectual activity; only an occasional harsh cry or inarticulate sound indicates the existence of mind.”

The other symptoms differ but little from the maniacal form. The duration of the attack varies from a few hours to half a day; its termination is usually abrupt, the patient falling into a condition of extreme exhaustion with stupor, or into a deep and prolonged sleep, from which he awakens without the slightest recollection of the attack through which he has passed.²¹

3. Acute Alcoholism, in Persons of Unsound Mind.—The insane, imbeciles, epileptics, and persons suffering from nervous diseases are, as a rule, abnormally susceptible to the action of alcohol, and present more or less striking peculiarities in the symptoms which it causes. Brief notice of certain of these peculiarities is in accordance with the scope and plan of this article.

In general paralysis propensity to alcoholic excesses is not rarely an early symptom. The subject is very susceptible to the action of alcohol, and under its influence rapidly passes into a state of intense excitement, characterized by incoherence, delirium, excessive restlessness, and unwillingness to seek repose until exhaustion is complete. It is under the influence of this easily-provoked alcoholic excitement that the vagabondage, quarrels, thefts, robberies, incendiarisms, and other grave crimes observed during the first stage of this form of insanity are often committed.

Imbeciles and idiots are likewise quickly, and often intensely, excited by alcohol. They are then apt to be quarrelsome, perverse, and ungovernable, defiant of authority, and capable of shocking crimes, often evincing latent vicious tendencies previously wholly unsuspected.

Epileptics are easily affected by alcohol, and usually violent in the stage of excitement; not rarely this period terminates in a true epileptic seizure.

The drunkenness of the dipsomaniac is characterized by a prolonged, uninterrupted stage of excitement without the stage of depression. Such individuals are capable of consuming in their periodical excesses large amounts of drink without the evolution of the ordinary successive phenomena of acute alcoholism.

Persons of unsound mind are, as a rule, so susceptible to the influence of alcohol, and suffer so promptly and intensely from its primary effects, that they are rarely able or permitted to consume a sufficient quantity to bring about a comatose state.

The irregular forms of acute alcoholism are only to be explained by the inherited or acquired constitutional peculiarities of individuals. To attempt to explain them in any case by the quality of the alcohol by which they are induced meets with the difficulty indicated in the fact that they are isolated and comparatively rare, even where the coarser spirits are habitually consumed. They occur in individuals who habitually commit excesses, but they cannot be viewed as manifestations of chronic alcoholism, for the reason that they also occasionally occur in those who are not habitual drinkers, and even in persons who have not for a long time previously tasted strong drink. Furthermore, as has been pointed out, they are not only occasionally, but indeed even as a rule, induced by relatively small amounts of alcohol. They are then the manifestations of idiosyncrasy. One of the striking peculiarities of this peculiar bodily organization is this very susceptibility to the action of alcohol in doses smaller than are taken with impunity by ordinary individuals. It is also characterized by a special tendency to delirium in febrile states, to hallucinations, to disturbances from trifling changes in climate, food, or manner of life, to irritability of the nervous system, and in particular of the vaso-motor system, and by a tendency to convulsions. With these tendencies is associated an unstable mental and moral character. Such persons are liable to headaches, vertigo, and epistaxis—signs of cerebral hyperæmia, which is easily induced—and their family histories indicate strong hereditary tendencies to neurotic disorders, and not rarely addiction to alcohol on the part of one or several ancestors.

But this idiosyncrasy is by no means always an inherited one. It is acquired as one of the results of profound disturbance of the nervous system, such as is produced by moral causes, by temporary or recurrent insanity, by wounds and injuries of the head, by the infectious diseases, especially syphilis, enteric and typhus fever, and small-pox, and by inflammations of the meninges.

What may be the precise mode of action of alcohol in the production of its acute effects yet remains a matter of conjecture. It cannot be doubted that its primary and direct action is upon the nervous system, and that the circulation is secondarily but rapidly implicated. But it is quite impossible to say, in the present state of knowledge, what this action is. It has been suggested that certain chemical modifications of alcohol in the blood, or of the blood itself in the presence of alcohol, cause these phenomena; that aldehyde is the active agent in their production; that the chemical changes by which alcohol is transformed into aldehydes, acetic acid, and finally into carbon dioxide, deprive the blood of the oxygen necessary for the proper performance of the functions of the nervous system. Unfortunately for these views, neither the presence of aldehydes in the blood in acute alcoholism, nor these transformations themselves, have yet been demonstrated, and a high degree of deoxygenation of the blood is frequently observed in asphyxia, the inhalation of nitrous oxide, etc., without the train of symptoms characteristic of the condition now under consideration.

It is more than probable that varying conditions of the cerebral circulation, secondary in themselves, have much to do in the causation of certain symptoms. The experimental investigations of Bernard and others have established the fact that during the period of excitement there is actual congestion of the meninges. This condition is transient, and reproduced after each repetition of the dose. After a time, or if the dose at first be excessive, the congestion is succeeded by anæmia.

PATHOLOGICAL ANATOMY.—Upon the examination of the bodies of persons who have died by accident while drunk or in consequence of drunkenness itself, deep congestion of the cerebral meninges, and especially of the pia, has been almost constantly observed. In the pia effusions of blood are occasionally encountered. The condition of the cerebral substance is not always the same. It is in a majority of the cases more or less deeply congested, yet it presents in other instances no appreciable departure from the normal state, and in a smaller number still there is actual anæmia.

The sinuses and choroid plexuses are distended with dark blood; the cerebro-spinal fluid is increased, and often tinged with blood; the ventricles are distended with fluid, which not rarely has an alcoholic odor. Occasionally the ventricles contain blood, and hemorrhage into the substance of the brain has been observed.

The condition of the elementary nervous tissues after death from acute alcoholism is not yet known.

The lungs are deeply congested, with small extravasations of blood into their substance, and often œdematous. Congestion of the liver, spleen, and kidneys in varying degrees of intensity is also seen. The pancreas is usually deeply injected, occasionally the seat of large extravasations of blood. The mucous membrane of the stomach is invariably deeply injected when the alcohol has been introduced into the organism in the ordinary manner. The observation of Caspar that post-mortem decomposition takes place with diminished rapidity has been denied by Lancereaux and others.

Other post-mortem conditions appear to be neither constant nor characteristic. The stomach usually contains partially digested food and alcohol. Lallemand, Perrin, and Du Roy observed, both during life and after death, in the blood of animals subjected to experiments, great numbers of minute glistening points, which upon microscopic examination proved to be fat-globules. The same condition has been observed in man, not only when death has taken place owing to acute alcoholism, but also when it has occurred during the digestion of a hearty meal without alcohol. The blood itself is often fluid and dark-colored; the heart sometimes empty, sometimes containing a few soft clots. Tardieu²² states that in sudden death during drunkenness pulmonary apoplexy and meningeal apoplexy, if not constant lesions, are at least extremely frequent, and almost characteristic. Baer, on the other hand, denies the occurrence of specific or characteristic lesions.

C. ACUTE POISONING BY ALCOHOL IN LETHAL DOSES.—The symptoms are much modified when overwhelming doses of strong alcohol are introduced into the organism at once or in the course of a short time. Here alcohol produces death as an acute poison. The cases may be arranged in two groups:

1. Corrosive Poisoning.—These cases are very rare. They are caused only by undiluted alcohol, and depend upon the action of this agent in coagulating albumen and disorganizing the tissues with which it comes in contact by its affinity for the water which they contain. Absolute alcohol is a powerful corrosive poison. It produces intense phlegmonous inflammation of the œsophagus and stomach, with erosion of the mucous membrane, accompanied by vomiting, diarrhœa with bloody stools, prostration, and stupor. Death occurs by heart-failure. Among the direct effects of large doses somewhat less concentrated are acute and subacute gastritis with characteristic symptoms.

Percy²³ injected by means of an œsophageal tube 90 grammes of absolute alcohol into the stomach of a dog. Death followed in the course of eight hours in consequence of violent gastro-intestinal inflammation with ulceration. Dujardin-Beaumetz and Andigie found the gastric and intestinal mucous membrane of dogs poisoned by alcohol, red, deeply injected, and “presenting at certain points a black coloration due to effused blood.” This fact they regard as worthy of note, because in their experiments the toxic agent was introduced, not by the mouth, but hypodermically, and they explain it by the supposition—which appears to me warrantable—that it is due to elimination by the mucous glands. Hence the congestion, softening, and hemorrhage.²⁴ These observers also found that the symptoms were more acute and the lesions more marked when poisoning was caused by propyl, butyl, or amyl alcohol than when it was produced by ethyl alcohol.

²³ An Experimental Inquiry concerning the Presence of Alcohol in the Ventricles of the Brain after Poisoning by that Liquid, together with Experiments illustrative of the Physiological Effects of Alcohol, London, 1839.

²⁴ Chatin and Gublier have emphasized the fact that certain poisons introduced by intravenous injection or by absorption through the respiratory tract are eliminated by the intestines, with the production of the same local symptoms as when administered by the mouth (Bulletin de l'Académie de Médecine, Séance du 6 Novembre, 1877).

2. Acute Narcotic Poisoning.—Much more common are the cases in which death is rapidly produced by excessive doses of ordinary diluted alcohol taken at once or rapidly repeated. This happens under various circumstances, as when a drunkard avails himself of some favorable opportunity to gratify to the full a bestial appetite, or upon a wager drinks a number of glasses of spirits in quick succession or a given quantity down, or when a man already drunk is plied by his companions for pure deviltry. Suicide by this means is, in the ordinary sense of the term, rare, and murder still more so. The latter crime has, as a rule, been committed upon infants and children. Blyth²⁵ estimates the fatal dose of absolute alcohol, diluted in the form of ordinary whiskey, gin, etc., at from one to two fluidounces for any child below the age of ten or twelve years, and at from two and a half to five ounces for an adult. In the instance recorded by Maschka²⁶ two children, aged respectively nine and eight years, took partly by persuasion, afterward by force, about one-eighth of a pint of spirits of 67 per cent. strength—about 1.7 ounces of absolute alcohol. Both vomited somewhat, then lay down. Stertorous breathing at once came on, and they quickly died. Taylor relates a case in which a quantity of brandy representing about two fluidounces of absolute alcohol produced death in a child seven years old.

The symptoms are uniformly the same. The period of excitement is transient or absent altogether; occasionally the patient falls at once to the ground while in the act of drinking or immediately thereafter; complete coma, interrupted by shuddering convulsions, may terminate in the course of a short time in death. If the fatal issue be delayed, there are vomiting and involuntary discharges; the respiration becomes slow, embarrassed, stertorous; the heart's action is feeble and irregular, the pulse almost or wholly imperceptible; the temperature rapidly falls several degrees: 90° F. has been observed. The pupils are dilated; insensibility and muscular resolution are complete. The face is bloated, cyanotic; the surface bathed in a clammy sweat; the mucous membrane of the mouth often swollen and blanched. Vomiting is usual, but not constant, and there is occasionally thin mucous diarrhœa, the stools being mixed with blood. If the patient survives any considerable length of time, acute superficial gangrene of the parts most exposed to pressure is liable to take place. Recovery is rare; its possibility is, however, increased in proportion as the subject is of vigorous constitution, previous sound health, beyond the period of childhood, not yet approaching that of physiological decadence, and as treatment is early instituted and carried out with judgment.

The diagnosis is difficult, almost impossible, in the absence of witnesses: it is rendered still more obscure by the fact that this, as other forms of alcoholic coma, may be complicated by cerebral or meningeal hemorrhage and by cerebral congestion, in themselves fatal—lesions the onset of which may have been the cause of mental aberration leading to the commission of impulsive alcoholic excesses.

The prognosis, in the highest degree unfavorable in all cases, is rendered yet more so by the occurrence of intense cerebral and pulmonary congestions.

The lesions found post-mortem are those of acute alcoholism, already described. As this form of alcoholic poisoning frequently occurs in the subjects of chronic alcoholism, the lesions of that condition are often encountered, and must be distinguished from those due to the lethal dose. Nor must we overlook the fact that in the action of alcohol just described we have to do with a process differing from ordinary acute alcoholism in degree rather than in kind—a consideration which tends to simplify our notions of the pathology of alcoholism in general.

II. Chronic Alcoholism.

The prolonged abuse of alcohol brings about a series of changes which affect alike the organism at large and its various structures. The changes thus brought to pass are of the most varied kind, and depend upon individual differences too manifold and complex for enumeration and classification. Among the more important of these individual peculiarities are those which relate to temperament, constitution, hereditary predisposition, occupation, social position, personal habits, tendency to or already-existing disease of particular organs and systems, and the like. The degree of the pathological change is determined by the strength and quantity of alcohol consumed and the duration of habitual excess. The human body is capable of adapting itself to the habitual consumption of large quantities of alcohol, just as to other directly acting agents of an injurious nature, such as foul air, bad drinking-water, and unwholesome food, or even to the action of substances dangerous to life, as opium or arsenic, and yet presenting for a considerable time the appearance at least of health. Degeneration of the tissues of the body and disorders of its functions are nevertheless surely produced. These alterations are not the less dangerous to health and life because they are insidious and remain for a time latent. Furthermore, like the habit of which they are begotten, they are progressive, and sooner or later declare themselves in open disease.

The condition, whether latent or manifest, that is produced by prolonged habitual alcoholic excess is designated chronic alcoholism.²⁷

²⁷ The writer, although fully aware of its imperfections, regards the above definition of the term as more in accordance with the present state of our knowledge of the subject, and therefore more useful, than any other that he has been able to find. It is scarcely necessary to repeat here that the restriction of the term chronic alcoholism to accidental or occasional manifestations of a permanent state is misleading and unscientific. The same criticism is applicable to the attempt that has been made to establish this condition as a substantive disease, chronic, progressive, and characterized anatomically by inflammatory, sclerotic, and steatogenous processes.

The symptoms of this condition, when fully established, differ within wide ranges in kind and degree. They are the manifestations of derangements of the viscera, of the nervous system, and of the mind. Varying among themselves according as the stress of the pathological action has fallen upon one organ or another, forming combinations at once curious and inexplicable, developing quietly, without event, almost imperceptibly at one time, breaking into the most furious paroxysms at another, they present for our study perhaps the most complex of chronic morbid conditions. The chronic alcoholism which is latent is not, therefore, always without symptoms. They are, however, often slight and escape observation, or when manifest they are not infrequently ascribed to other causes; or, again, their etiological relations being concealed or overlooked, they are exceedingly obscure and puzzling. This is especially the case in the chronic alcoholism produced by the secret tippling of otherwise respectable persons, and especially women.

To facilitate description, we shall consider the derangements of the viscera, the nervous system, and the mind in regular order, according to the scheme on p. 574. But the reader will observe that whatever may be the prominence of particular symptoms or groups of symptoms in any given case, all parts of the organism are involved, and that there is no such thing as chronic alcoholism restricted to any particular viscus or group of viscera, to the nervous system, or to the mind.

A. VISCERAL DERANGEMENTS.—There is nothing specific in the lesions of chronic alcoholism. The chronic hyperæmia, steatosis, and sclerosis induced by alcoholic excesses differ in no respect from those conditions brought about by other causes. That which is specific is the evolution of a series of morbid changes in the different structures of the body under the influence of a common and continuously acting cause. The digestive system is affected, as a rule, long before the vascular or the nervous system.

1. Local Disorders.—a. Disorders of the Digestive System.—The Mouth and Throat.—The action of insufficiently diluted alcohol upon the mucous tissues is that of an irritant. The habitual repetition of this action causes subacute or chronic catarrhal inflammation. The condition of the tongue varies with that of the stomach. The mouth in acute alcoholism is apt to be pasty and foul, the tongue slightly swollen and coated with a more or less thick yellow fur; there is often also an increase of saliva; in chronic alcoholism the tongue is usually small, sometimes red, sometimes pale, often smooth from atrophy of the papillæ, not rarely deeply fissured. In a word, the condition of this organ is that seen in the various forms of subacute or chronic gastritis. The salivary secretion is often notably diminished, the sense of taste impaired. Relaxation of the throat and uvula and granular pharyngitis are common. Those who, whilst leading a sedentary life, are inclined to the pleasures of the table and a free indulgence in spirituous liquors often suffer from these affections. Mackenzie²⁸ states that the worst cases of chronic catarrh of the throat generally arise from the habitual abuse of the stronger forms of alcohol. The associated influence of tobacco in the causation of this group of affections is not to be disregarded.

²⁸ Diseases of the Pharynx, Larynx, and Trachea, 1880.

Lancereaux encountered ulceration of the œsophagus, and Bergeret a case of narrowing of that organ, in chronic alcoholism.²⁹

²⁹ Peeters regards it as probable that the connective-tissue hyperplasia and resulting stenosis seen in the stomach as a result of the action of alcohol may also occur in the œsophagus.

The Stomach.—In addition to functional dyspepsia, which is scarcely ever absent in chronic alcoholism, all forms of gastritis, from simple erythematous inflammation of the mucous membrane to sclerosis and suppurative inflammation of the stomach, are encountered. Armor³⁰ assigns to the habit of spirit-drinking, especially to the habit of taking alcohol undiluted on an empty stomach, a high place among the causes of indigestion. He regards this habit as a prominent factor in the production of chronic gastric catarrh—a condition very frequently present in indigestion. This observer also regards the excessive use of alcohol as the most frequent among the direct exciting causes of gastric inflammation in this country, exclusive of acid or corrosive poisons. Next to errors in diet as a cause of chronic gastritis he places the immoderate use of alcohol, especially by persons whose general health and digestive powers are below a healthy standard. The primary lesions are vascular dilatation and hyperæmia. The mucous membrane is discolored, red or bluish, in scattered patches of varying size, with occasional ecchymoses of a bluish hue or spots of pigmentation. These patches occupy more commonly the region of the cardia and the lesser curvature. Vascular injection is conspicuous; the veins are dilated, tortuous; the mucous glands hypertrophied; the surface covered with thick, ropy, acid-smelling mucus. After a time permanent changes in the mucous membrane are set up. It undergoes atrophy or softening; or, again, it becomes hardened, thickened, and contracted, its rugæ more prominent, its surface mammilated—sclerosis. Grayish-brown pigmentation, the remains of former blood-extravasations, is seen at many points. Minute retention-cysts are formed in consequence of the occlusion of the ducts of certain glands. The submucous connective tissue and the muscular coat occasionally undergo, in consequence of prolonged gastritis, local hypertrophy.

³⁰ See this System of Medicine, Vol. II. pp. 446, 464, 470.

Acute suppurative inflammation of the stomach, with purulent infiltration of, or the formation of abscesses in, the submucous tissue, has been met with in drunkards. It is extremely rare, and results from the violent irritant action of large doses of strong alcohol in subjects debilitated by previous excesses.

Gastric ulcer is much more common. The abuse of alcohol is regarded as an indirect cause of this lesion by the majority of writers. In the present state of knowledge alcohol as usually taken can scarcely be regarded as a direct cause of ulceration. Nevertheless, gastric ulcer is relatively common in alcoholic subjects. Leudet³¹ found gastric ulcer in 8 of 26 necropsies of drunkards. Baer and Lentz also regard the abuse of alcohol as a very common cause of ulceration. The ulcers are usually superficial, occupy by preference the neighborhood of the cardia and the lesser curvature, and are apt to be multiple. In these respects they differ from simple gastric ulcer. The latter lesion is also probably as frequent, if indeed not more frequent, in individuals dying of chronic alcoholism than in others.

³¹ Clinique médicale de l'Hôtel Dieu à Rouen, 1874.

The view formerly entertained that alcohol was an important cause of cancer of the stomach has been shown by Kubik, Magnus, Huss, Engel, and others to be untenable. Carcinoma ventriculi is rarely associated with chronic alcoholism.

The dimensions of the stomach are rarely normal. Dilatation is usually present in the early stages, and in beer-drinkers throughout; in the advanced course of alcoholism due to spirit-drinking the organ undergoes, in consequence of changes secondary to prolonged inflammation, more or less contraction, which is in many cases irregular.

Dyspeptic symptoms are common: the appetite is variable, irregular, and at length wholly lost. There is especially distaste for food in the morning. This, together with the disordered state of the secretions of the mouth and a feeling of nervous depression on rising, leads to the disastrous habit of taking spirits early in the day. Gastric digestion is performed with difficulty; it is accompanied by sensations of distension and weight, by flatulence and acid eructations. Heartburn is a common symptom. The drunkard is not rarely tormented by an uneasy craving or sense of emptiness in the region of the stomach, which he temporarily allays by nips and pick-me-ups and morsels of highly-seasoned foods at odd times, with the result of still further damage to his digestion and the complete loss of appetite for wholesome food at regular hours. In the course of time the characteristic morning sickness of drunkards is established. On arising there is nausea, accompanied by vomiting—sometimes without effort or pain, at others attended by distressing retching and gagging. The matter vomited consists usually of viscid mucus, at first transparent, then flaky, and at length, if the efforts be violent, of a green or yellow color from the admixture of bile. These symptoms ordinarily do not recur until the following day. In other cases vomiting is more frequent, recurring at irregular periods during the day, and not uncommonly an hour or two after the ingestion of food. When gastric ulcer is present, portions of the vomited matter are often dark and grumous like coffee-grounds or the settlings of beef-tea, and are found upon microscopic examination to contain blood-corpuscles. Actual hæmatemesis may also occur under these circumstances, and be repeated from time to time. The quantity of blood thrown up is frequently small; at times, however, it is excessive, and occasionally so great as to cause death.

Common as are the evidences of gastric disturbance in chronic alcoholism, they are far from being constant, and it is worthy of note that in proportion to the number of the cases serious gastric affections are, except in the later stages, relatively infrequent.

The Intestines.—Lesions of the small intestine due to alcoholism are extremely rare. Even when simple or ulcerative inflammation of the stomach is localized at, or extends to, the pylorus, it rarely passes any great distance into the gut. The large intestine is, on the contrary, frequently the seat of chronic inflammatory processes. Here we find vascular engorgement, patches of pigmentation, localized thickening of the mucous and submucous tissues, enlargement of the solitary glands, and an excessive secretion of viscid mucus. The tendency to permanent vascular dilatation, which is a characteristic result of alcoholic habits, constitutes a powerful predisposing influence in the causation of hemorrhoids, which are common. Alcohol acts directly upon the hemorrhoidal plexus of veins, and indirectly by causing permanent congestions of more or less intensity in the greater number of the abdominal viscera. When a prolonged course of excesses in alcohol has led to chronic congestion with hypertrophy, cirrhosis, or other structural change in the liver which is capable of causing permanent mechanical obstruction of the portal circulation, hemorrhoids constitute a very common affection in the group of morbid entities secondary to these conditions.

The symptoms of intestinal derangement are in the beginning, as a rule, slight and occasional. They consist of uneasy sensations or colicky pains in the abdomen, a feeling of fulness with or without tympany, and constipation alternating with diarrhœa: in a word, they are the symptoms of acute or subacute intestinal indigestion terminating in an attack of intestinal catarrh. Attacks of this kind repeat themselves in a considerable proportion of the cases with variable but increasing frequency, until at length the conditions of which they are the expression become permanent, and the patient suffers, among other distressing symptoms hereafter to be described, from chronic diarrhœa. The stools are now of the most variable character—occasionally bilious, sometimes containing small dark scybalous masses, rarely formed, but usually containing more or less abnormal mucus, too much fluid, and traces of blood. Indeed, at this stage several causes—among which I may mention visceral congestions, local inflammation of the intestinal mucous membrane, dilatation of the hemorrhoidal veins, and structural changes in the liver—conspire to determine blood toward the interior of the intestinal tube. Traces of blood in the stools are therefore frequent, and actual hemorrhage and the appearance of the dark, tarry, and altered blood formerly described under the term melæna are by no means rare. Colliquative diarrhœa and dysenteric attacks also occur, and at length an intense enteritis with uncontrollable diarrhœa may end the life of the patient. The conditions just described lead to rapid emaciation, and contribute when present to the establishment of the cachexia so marked in many cases of chronic alcoholism.

The Glands.—The salivary glands were found by Lancereaux³² to have undergone softening, with granulo-fatty changes in their epithelium. If such changes are among the usual effects of alcohol, they are doubtless productive of alterations in the saliva, which explain, in part at least, the dryness of the mouth so frequent among drunkards.

³² Dictionnaire de Médecine, art. “Alcoholism.”

The pancreas is, as the result of interstitial inflammation, the seat of similar changes. It is sometimes enlarged and softened, sometimes atrophied, shrivelled, or cirrhotic. In the latter condition its consistence is firm, its surface uneven, its color deep yellow, brown, or pale. Hyperplasia of the interacinous connective tissue, with subsequent contraction and atrophy and destruction of the glandular tissue, characterizes the more chronic forms of pancreatitis, and the organ is frequently the seat of scattered minute blood-extravasations. I have already alluded to the enlargement of the solitary glands which constitutes a feature of the condition of the large intestine. The solitary glands and Peyer's patches of the small intestine are rarely altered.

b. Disorders of the Liver.—Next in order to the stomach, the liver is more directly exposed to the action of alcohol than any other viscus. For this reason lesions of the liver are frequent and grave. It is worthy of note, however, that in a small proportion of cases of chronic alcoholism terminating fatally, with widespread evidences of the destructive action of alcohol upon the other organs of the body, the liver has been found, both in its macroscopic and microscopic appearances, wholly normal. Absorbed by the gastric vessels, alcohol passes directly, by way of the portal vein, into the parenchyma of the liver, there giving rise to various disturbances, the nature of which is determined by the tendencies of the individual on the one hand, and on the other hand by the character of the alcohol consumed. The danger of hepatic disease is in direct proportion to the amount and the concentration of the alcohol habitually taken. The steady drinkers of spirits of whatever kind, whether gin, brandy, whiskey, or rum, present the largest proportion of diseases of the liver. These affections are far less common among beer-drinkers, and infrequent among wine-drinkers in wine-growing countries. In this connection it is to be borne in mind that the presence of food in the stomach retards to some degree the absorption of the alcohol ingested, and to a certain extent constitutes a means of dilution.

Hepatic disorders due to alcohol may be arranged in two groups: first, congestion and inflammation; second, fatty infiltration or steatosis; and the inflammatory process may affect chiefly the interstitial connective tissue on the one hand, giving rise to sclerosis, or on the other the glandular substance, constituting a true parenchymatous inflammation.

Congestion.—Congestion of the liver is an early lesion. It is brought about by the direct irritant action of the alcohol itself in part, and in part by the extension of inflammation from the stomach by continuous mucous tracts. Its development is insidious. Anatomically, the condition is characterized by vascular dilatation, moderate tumefaction, slight increase in the consistence of the organ; the surface is of a deeper red than normal; on section the color is more intense and the oozing more abundant. At a later period we have, as the result of chronic congestion, the cyanotic liver; the color is brownish or violet, mottled, and on section the surface is granular and the lobules distinct. The organ may now be somewhat diminished in size, but it lacks the firmness of sclerosis and the hobnail appearance due to the contraction of the interlobular connective tissue in that condition.

The symptoms of congestion of the liver are the familiar symptoms of gastro-hepatic catarrh, varying from the transient disturbance known as biliousness to serious sickness, characterized by acute gastro-intestinal phenomena, with vomiting, headache, and other derangements of the nervous system—constipation, succeeded by diarrhœa and by more or less distinct jaundice. The graver forms of hepatic congestion are characterized by intense nausea, frequent vomiting, pain and soreness in the epigastrium and right hypogastrium, the physical signs of augmentation of the volume of the liver, and well-marked yellow discoloration of the conjunctivæ and skin. These attacks are usually afebrile: the pulse is slow; there is considerable nervous and mental depression, a tendency to vertigo, and occasional syncope. The urine is scanty and high-colored, and presents the reactions of bile-pigment. Muscular tremor, especially marked in the extremities and tongue, is often present, but is to be attributed rather to the direct action of alcohol upon the nervous system than to the condition of the liver.

Hepatitis.—There are two principal forms of inflammation of the liver induced by alcohol—parenchymatous hepatitis and interstitial hepatitis or sclerosis.

Several varieties of parenchymatous hepatitis have been described. The anatomical discrimination of these varieties is attended with less difficulty than their clinical diagnosis. One of the more serious is diffused parenchymatous hepatitis or acute yellow atrophy. Alcoholic excesses appear to constitute a predisposing influence to this grave disorder (Lentz). In several cases prolonged and repeated excesses have preceded its development. It is a true parenchymatous inflammation, in which the glandular elements of the organ undergo disintegration. The liver is diminished in volume in all its diameters. It is of a uniform yellow color; its tissue is soft and friable; upon section the hepatic cells are found to be replaced by a granular detritus mingled with globules of coloring matter and a greasy, grayish-yellow liquid exudation.

The symptoms of this affection are those of an acute parenchymatous hepatitis of the gravest kind. In the early stages there is intense jaundice, gastro-intestinal disturbance, and fever, followed by speedy evidences of profound toxæmia. The patient rapidly falls into the so-called typhoid state, with a tendency to coma. The prognosis is, in the greater number or cases, a fatal one. So close is the resemblance between acute yellow atrophy of the liver and the phenomena of acute phosphorus-poisoning that by many observers these two conditions are held to be identical.³³

There is little doubt that the view now generally held, that acute yellow atrophy is due to the action of some unknown toxic principle, is correct. Alcoholic excess must therefore be regarded merely in the light of a predisposing influence. Acute yellow atrophy of the liver is an exceedingly rare disease.

Suppurative Hepatitis.—Abscess of the liver is in temperate climates infrequent as the direct result of alcoholic excess. It is frequently ascribed, however, to improper alcoholic indulgence, especially when combined with the eating of large quantities of improper food, in tropical and subtropical climates. A form of hepatitis has been described by Leudet under the head of chronic interstitial hepatitis with atrophy. The symptoms are for the most part not very well marked, and consist chiefly in general malnutrition, which may in fact be dependent upon the associated gastric disturbance. Chronic jaundice is usually present.

Interstitial Hepatitis.—Cirrhosis of the liver is in a large proportion of cases directly attributable to alcoholic excess. In this view the greater number of observers coincide. But that alcohol is not the sole cause of chronic interstitial hepatitis has been abundantly established. As long ago as 1868, Anstie³⁴ wrote as follows: “Considering the enormous quantities of spirituous liquors which are drunk by many of the patients who apply for relief from the consequences of chronic alcoholism, it would be natural for the reader who holds the usual opinion as to the origin of cirrhosis of the liver to expect that serious symptoms produced by the latter disorder must often complicate cases of the former. The case is, however, far otherwise in my own experience. Of the immense number of patients in whom the nervous disorder has been clearly identified, I have only seen thirteen cases in which the symptoms of cirrhotic disease called for any special treatment, although a certain degree of cirrhosis was doubtless present in many of the others; and I cannot avoid the conclusion that some very powerful element over and above the influence of alcoholic excess is needed to produce the severe type of that disease.” Formad³⁵ states as the result of his investigations as coroner's physician of the city of Philadelphia that cirrhosis of the liver is much less common in alcoholic subjects than has been generally thought. My own experience during eleven years as attending physician at the Philadelphia Hospital leads me to endorse this opinion.

The anatomical lesions of chronic interstitial hepatitis consist essentially in hyperplasia and hypertrophy of the connective tissue of the organ. The progress of the affection is insidious and gradual; some degree of enlargement, due in part to congestion and in part to interstitial exudation, is followed by gradual diminution, with retraction of the new connective tissue. When the connective-tissue new formation is excessive, and retraction fails to take place, the organ remains permanently enlarged (hypertrophic cirrhosis). During the first period the volume of the organ is increased, its consistence is more firm, and its surface is slightly granular. The second period is characterized by induration, with diminution of the volume of the organ and alteration of its form. The surface is uneven, deeply granular, and usually of a mottled yellow color. The tissue is firm, creaking under the knife. The connective tissue is enormously increased, the glandular elements being proportionately atrophied.

The contracting connective tissue exercises at the same time a compressing influence upon the hepatic cells and upon the vascular supply throughout the organ; the radicals of the portal vein and the branches of the hepatic artery are alike compressed, and in part obliterated. The same is true of the bile-ducts. The functional activity of the liver, at first diminished, is finally, to a considerable extent, arrested. In consequence of these physical alterations in the structure of the organ, the symptoms, which are at first insignificant, become progressively more grave, until at length they constitute complications of the most serious kind.

It can be no longer asserted that the interstitial hepatitis produced by alcohol presents specific characters. It nevertheless differs in many respects from that form due to valvular lesions of the heart, in which there are induration, usually augmentation in the volume of the organ, and persistent congestion. Congestion, in truth, is the chief characteristic of the latter form, in which the surface is smooth and glistening, of a deep brown or violet hue, and on section yellowish or brown—a condition which has been well described under the term cyanotic liver.

Sclerotic changes due to alcohol usually affect the organ throughout. In this respect alcoholic cirrhosis differs from that form due to syphilis in which the lesions are irregularly distributed.

The functional disturbances due to cirrhosis are, in the beginning, obscure in themselves and masked by the concomitant gastric derangement. Later, ascites constitutes the chief as well as the most constant symptom. It is rarely altogether absent. Emaciation is also a prominent symptom. No affection, not even diabetes or phthisis, produces loss of flesh so rapid, so marked, and so significant as cirrhosis of the liver in chronic alcoholism. Not only do the adipose tissues waste, but the muscles themselves undergo rapid atrophy. This fact is not surprising when we consider that the lesions of the liver give rise to grave interference with every function of that organ. In addition to the more common gastric symptoms, there is constipation, not rarely alternating, without assignable cause, with serous and sometimes bloody diarrhœa. Epigastric distress, epistaxis, and hemorrhages from other mucous surfaces are common, and are due in part to the disturbance of the general circulation, and in part to alterations in the character of the blood itself. The physical signs indicate in the early stages increase, and afterward diminution, in the volume of the liver. Enlargement of the superficial abdominal veins is a characteristic sign. Cirrhosis of the liver is a grave affection, the course of which, at first slow, afterward more rapid, almost invariably leads to a fatal termination.

Fatty Degeneration of the Liver.—Steatosis of the liver is of extremely common occurrence in the advanced stages of alcoholism. The anatomical changes consist in accumulation of fat-globules in the liver-cells. French writers distinguish two varieties of hepatic steatosis: first, that in which the cellular elements undergo no change beyond that of an accumulation of fat-globules within their substance; and second, that in which the liver-cells undergo an actual disintegration, in the course of which fat-granules are formed, and which is, as a matter of fact, a true fatty degeneration. The first of these conditions is not incompatible with the functional integrity of the organ, and is in many instances unattended by symptoms, being discovered only upon examination after death. Its occurrence is to be explained by the imperfect oxidation of waste products due to the constant presence of alcohol in the blood, and by the habitual excess of fat in the latter fluid. When fatty infiltration is of moderate amount there are no changes in the volume or the contour of the organ, and the condition is recognized only on microscopical examination. At a later stage the organ becomes enlarged, particularly in its antero-posterior diameter. The surface is now smooth and glistening, its color yellow or reddish-yellow; upon section it is anæmic, of a yellowish color, with patches of a reddish hue, and its consistence is diminished. The indentation caused by pressure of the finger persists. Under the microscope the hepatic cells are enlarged, rounded, packed with fat-globules of varying size. In some of the cells these globules coalesce and form more or less extensive drops of fat. The bile which is secreted in this condition presents in most instances the normal characteristics.

Disorders of digestion do not occur in consequence of the fatty change in the liver until the lesion has reached an advanced stage; nevertheless, they constitute the earliest symptoms of this condition. Imperfect digestion, accompanied with flatulence, distension of the belly, epigastric tenderness, with light-colored stools, and constipation alternating with diarrhœa, are common symptoms. There is no pain properly referable to the region of the liver. Whilst icterus does not occur, there is, nevertheless, a peculiar earthy pallor of the complexion and persistent greasiness of the skin—conditions, however, which are not in themselves sufficiently marked to possess, in the absence of other signs, clinical value.

The second form of fatty degeneration, in which the liver-cells undergo actual and destructive metamorphosis, accompanied by the production of fat, is of a much more serious character. It appears to constitute the stadium ultimum of various forms of interstitial hepatitis, and is manifested by symptoms of the gravest character, in many particulars much like those met with in acute yellow atrophy—namely, visceral congestions, hemorrhages from mucous surfaces, serous effusions, profound and rapidly developing anæmia, nervous depression, and coma.

Biliary Catarrh.—The biliary ducts are usually the seat of catarrhal inflammation, due less perhaps to the direct irritant action of the alcohol than to the extension of the inflammation of the gastric mucous membrane in the form of gastro-duodenal catarrh. Gall-stones are not common in alcoholism.

The spleen is, as a rule, enlarged, soft, and friable; occasionally it is small and shrivelled. No characteristic changes in its contour and structure have been recorded.

The great omentum and mesentery are loaded with fat, very often to an extreme degree. This condition is more marked in the chronic alcoholism of beer-drinkers than in that of spirit-drinkers. Not infrequently there are found evidences of chronic peritonitis, which has been attributed by Lancereaux, in the absence of other assignable cause, to the effect of alcohol itself. The symptoms of this condition are usually obscure, consisting of diffused dull pain, augmented upon pressure, diarrhœa, digestive troubles, and abdominal distension, sometimes voluminous, often irregular.

c. Disorders of the Respiratory System.—The Larynx.—Catarrhal inflammation of the mucous membrane of the air-passages is common in drunkards. Some degree of subacute or chronic laryngitis is an early symptom of chronic alcoholism. It may result from repeated attacks of acute alcoholism, or it may be among the first signs of excesses that are continuous, without at any one time being extreme. In the production of this local trouble the direct action of alcohol is reinforced by the foul and smoke-laden air of the apartments in which tipplers spend much of their time and by heedless exposure to the vicissitudes of the weather. The anatomical changes are those of chronic laryngitis in general, hyperæmia of the mucous membrane with minute ecchymoses, local destruction of epithelium with superficial ulcerations or granulating surfaces. The mucus is often thick, opaque, and adherent.

These lesions are accompanied by more or less decided impairment of function. The voice is hoarse and husky; there is fatiguing laryngeal cough, usually harsh and grating in character, and attended by scanty muco-purulent expectoration. This cough is often paroxysmal; especially is it apt to be so on rising, and it then provokes the vomiting previously described.

The Bronchi.—After a time similar anatomical changes are brought to pass in the bronchial tubes. Subacute bronchitis is little by little transformed into the chronic form, characterized by hyperæmia and thickening of the mucous membrane, extending to the finer twigs, with submucous infiltration and implication of the connective-tissue framework of the lung. The exudation, tough and adherent or fluid and copious, occasions more or less frequent cough, and interferes with the function of respiration. Hence it is common to encounter in the subjects of chronic alcoholism bronchiectasis, pseudo-hypertrophic emphysema, easily excited or permanent dyspnœa, asthmatic seizures, and some degree of cyanosis. These local affections, interfering with the circulation of the blood and its proper aëration, react unfavorably upon the nutrition of the organism at large, and largely contribute to the production of the ultimate dyscrasia.

The Lungs.—Pulmonary congestion and œdema are of common occurrence. Favored by the action of alcohol upon the vaso-motor system, they are readily excited by the careless habits and frequent exposures of the subject. The lesions occupy by preference the lower and posterior parts of the lungs, and consist in relaxation of the parenchyma, with vascular dilatation and serous infiltration. The vesicles are capable of distension, but contain little air. The tissue is friable, deep-red or brownish in color, and floats upon water. The symptoms of this condition are sometimes obscure: usually they consist in a sensation of constriction of the thorax, more or less dyspnœa, mucous expectoration, sometimes streaked with blood, and lividity of the countenance and finger-tips. The chief physical signs are impaired percussion resonance and mucous, subcrepitant, and occasionally a few scattered crepitant râles.

Pulmonary Apoplexy.—When the congestion is extreme, blood may escape into the parenchyma of the lung with laceration of its substance. This lesion is more frequent in intense acute alcoholism than in the chronic form.

Pneumonia.—Habitual alcohol-drinkers are far more liable to pneumonia than others. It has even been asserted that alcohol is of itself capable of acting as an efficient exciting cause. Whilst it is indisputable that the action of this agent upon the pulmonary blood-vessels and in favoring pulmonary congestion constitutes a powerful predisposing influence, it cannot be admitted, regard being had to the fact that it is largely eliminated by the lungs, that alcohol can, in the absence of a specific cause, ever produce a specific acute febrile disease, such as croupous pneumonia. The pneumonia of alcoholic subjects, like that of aged persons and that occurring in the convalescence from acute diseases, is apt to be latent. The exudation is often of limited extent; the symptoms are insidious, and the striking clinical features of the ordinary frank form of the affection are not rarely absent altogether. It is no infrequent occurrence that pneumonia is overlooked in the delirium tremens which it has induced.

The anatomical changes are those of the ordinary form. The prognosis is always grave. When recovery occurs resolution is often tedious and prolonged.

Catarrhal pneumonia is also common. It is marked by its usual phenomena.

The most striking fact in the pneumonia of alcoholic individuals is the contrast between the local and the constitutional symptoms. The former are in the greater number of the cases insignificant and easily overlooked. Even the physical signs, when sought for, are often obscure and indeterminate: relative dulness, enfeebled or absent vesicular murmur, faint scattered crepitation masked by mucous râles, and a bronchial respiratory sound scarcely appreciable, are all that can be detected upon physical examination. In strong contrast to this almost negative picture is that of the constitutional disturbance, which is commonly of the gravest kind. The prostration is extreme; there is delirium with tremor, restlessness, sleeplessness, mental agitation, profuse sweating, feeble action of the heart, gastro-intestinal irritation, with vomiting and often complete inability to retain food. The temperature-curve lacks the characters of pneumonia of the ordinary form. Not seldom is febrile movement absent altogether.

The view that alcohol, independently of and in the absence of other lesions, occasionally produces changes in the lungs analogous to the chronic interstitial inflammatory processes of cirrhosis of the liver—i.e. fibroid phthisis—is not borne out by clinical or pathological investigation, and appears to be wholly without foundation in fact.

Pulmonary Phthisis.—The question whether or not chronic alcoholism exerts any influence in the production and evolution of pulmonary phthisis has been the subject of no little fruitless controversy. There are medical men of experience who do not hesitate to affirm that the abundant use of alcohol constitutes in certain cases an actual prophylaxis, while there are others who insist with equal positiveness that alcoholic excesses favor the development of this affection. Whatever may be the influence of alcohol in depressing the forces of the body and in the production of serious lesions of pulmonary structures, and thus predisposing the subject to phthisis, it can be asserted with confidence that it does not directly cause any form of phthisis whatever. The alcoholic phthisis of Lancereaux, Richardson, Drysdale, and others cannot be now regarded as a distinct, independent affection. The process of exclusion by which alcohol was made to seem the real cause of the disease in 36 of 2000 of the cases examined by Richardson was not sufficiently rigid to meet the requirements of our present knowledge. There is reason to believe that by its favorable influence upon the appetite and digestion, its power to reduce temperature, its retarding influence upon tissue-waste, alcohol in moderate quantities is of great use in the management of this affection. That phthisical subjects occasionally seem to derive benefit from, and to lengthen their lives by, excesses in alcohol is capable of explanation—first, by the fact that an extraordinary tolerance for alcohol is natural to or acquired by certain individuals; and, second, by the favorable influence of alcohol upon ulcerative and suppurative processes, and in determining connective-tissue new formation—a process by which certain inflammatory products, including tubercle, are capable of being rendered inert. The foregoing remarks are applicable to all forms of pulmonary phthisis.

The Pleuræ.—The pleura is sometimes the seat of patches of fibrinous exudation of varying extent and thickness, which are, according to Lentz, the expression of the formative action which constitutes one of the modalities of alcoholism, and which are of the same nature as the fibrinous exudations which occur in the peritoneum and the dura mater. These false membranes cause pleural adhesions, and occasionally contain within their meshes a turbid serous fluid.

d. Disorders of the Circulatory System.—The Heart.—This organ is usually implicated to a greater or less extent in the course of chronic alcoholism. Lesions of the muscular substance are more common than those of the valvular apparatus.

Hypertrophy is common. It affects usually both sides of the heart—the left, however, more than the right—and is associated with some degree of dilatation. The part played by alcohol in the production of cardiac hypertrophy is a dual one: first, that of constantly-repeated direct stimulation of the heart; second, that of the indirect stimulation to over-action caused by the necessity to overcome the obstacles which the lesions of the viscera interpose to the circulation of the blood in the later periods of the disease. Nor are the lesions of the blood-vessels themselves, hereafter to be described, without influence in inducing hypertrophy. Bollinger and Schmidbauer have shown that the habitual consumption of beer in excessive quantities leads to cardiac hypertrophy of characteristic form. Both sides of the heart participate in the overgrowth: there is enormous increase in the volume of the primitive muscular elements, with enlargement of the nuclei. Whether or not actual numerical increase in the muscular fibres takes place cannot be determined. This form of enlargement of the heart occurs in the absence of lesions of the valves, disturbances of the pulmonary circulation, arterial sclerosis, atheroma, or granular kidneys. Some few of these cases of so-called idiopathic hypertrophy are perhaps due to prolonged excessive bodily effort and bodily strain. But the greater number are only to be explained by habitual excesses in beer-drinking, as shown by carefully worked-out personal histories of the patients. Neither fatty degeneration nor myocarditis enters into the pathological process under consideration. The hypertrophy is due to the direct action of the alcohol consumed, to the enormous amount of fluid introduced into the body, and to the easily-assimilated nutritive constituents of the beer itself. Furthermore, such habits are often associated with great bodily activity and a relatively luxurious manner of life. The greater number of alcoholic subjects who suffer from this form of hypertrophy perish after brief illness with symptoms of heart-failure. At the necropsy are discovered moderate dropsy, congestion and brown induration of the lungs, congestion of the liver, spleen, kidneys, and other organs, bronchitis and moderate serous effusions or general anasarca. Death is probably due to paralysis of the cardiac nerves and ganglia. This form of hypertrophy is of course much more common among men than among women. It is much less common in this country than in Germany, but is occasionally met with among brewers' employés.

Fibroid Degeneration.—This condition has been ascribed to a number of causes, among which long-continued excess in alcohol is unquestionably an important one. Bramwell holds the opinion that in a certain proportion of cases of this description, in which fibroid degeneration of the heart is connected with similar changes in the kidneys (sclerosis), the lesions of both organs are due to alcoholism. Alcoholic fibrosis differs in no respect from that due to other causes. The condition may escape recognition by the unaided eye if it be disseminated throughout the muscle and the change consist in thickening of the perimysia around undivided fibres. The heart is larger than normal, perhaps a little paler, and its consistency a little more firm. When, as is more commonly the case, the fibroid change is localized, and masses of new tissue are developed in and around the muscular fibres, the heart assumes a flecked or streaked appearance, due to the contrast between the yellowish-white fibroid tissue and the brownish-red muscular structure. The microscope shows excessive development of fibrous tissue, with atrophy of muscular fibres. The effect is to weaken the force of the heart's action, and to weaken the walls of the cavities at the affected parts in such a manner as to cause local bulgings or cardiac aneurisms.

The symptoms and physical signs of fibroid degeneration of the heart are very obscure and indefinite, and the diagnosis is always attended with difficulty, and in many cases is impossible. Jubel-Renoy, however, regards the diagnosis as having already attained some clinical exactitude, and regards as important the association of the following diagnostic data: first, feebleness of the systole and the pulse, with augmentation of the frequency without irregularity; second, moderate enlargement, varying within considerable limits; and third, absence of murmurs in the greater number of the cases. Death is apt to occur suddenly. Welch, upon investigation of the clinical histories of cases in which fibroid degeneration of the heart was found after death, concluded that they might be clinically grouped as follows: first, cases in which there is no symptom of heart disease; second, cases of sudden death without previous heart symptoms; third, sudden death preceded by one or more attacks of angina pectoris; fourth, after cardiac insufficiency of a few days' standing; and fifth, in cases of old heart disease.

Fatty Heart.—Under the term fatty heart two distinct pathological conditions are comprised. Of these the first is fatty infiltration, which consists in an excessive development of the normal subpericardial fat, with a deposition of fat-cells in considerable number between the muscular fibres of the myocardium. This condition occurs chiefly in individuals suffering from general obesity, and is particularly apt to occur in alcoholic obesity. Large masses of fat fill the grooves and furrows of the organ, the surface of which is covered with a thick layer of yellowish fat. The right heart is first and most affected, but in advanced cases the whole heart may be encased in a thick fatty layer. When the fat-cells infiltrate the intermuscular spaces, they exert pressure which may produce atrophy and degeneration of the muscular elements. This condition may exist to a certain extent without symptoms, but it is, however, apt to be manifested by a certain amount of cardiac dyspnœa and inability to endure excessive strain or acute illness. In cases in which the fatty infiltration attains a high grade, inducing by mechanical pressure degenerative changes in the muscular substance of the heart, there are signs of embarrassment of the circulation. The precise diagnosis is usually difficult, often impossible.

The second form of fatty heart is known as fatty degeneration, and consists in changes in the muscular fibres by which the albuminoid constituents are broken up and replaced by microscopic particles of fat. After a time the transverse striæ disappear, and the functional activity of those muscular fibres which are affected is completely lost. All conditions which interfere with the supply of oxygen to the muscular tissue or which seriously derange its nutrition are capable of producing fatty degeneration. Among these are alcoholic excesses. The color of the heart is paler than normal, usually fawn or pale buff. It has been described as the faded-leaf color. The consistence is softer than normal, the wall of the heart in many instances being readily broken down by the pressure of the finger. The left ventricle is the part most likely to be affected, the papillary muscles being often profoundly altered. Next in order the right ventricle is involved, then the left auricle, and finally the right auricle. When this form of degeneration is due to disease of the coronary arteries, the lesion is usually localized, sometimes limited to the distribution of the branch of the artery which is affected.

Upon microscopical examination the affected muscular fibres are found to contain minute molecules of fat, often of a uniform size, sometimes arranged in rows, but commonly distributed irregularly throughout the substance of the fibre. The transverse striæ are indistinct, and sometimes wholly absent. The functional activity of the affected fibres is seriously interfered with or wholly lost, and as a result the force of the circulation is greatly weakened. These two forms of fatty change are occasionally associated. Among the more common symptoms are shortness of breath upon exertion, with dry hacking cough. In advanced cases the dyspnœa may become constant. The fatal issue is sometimes preceded by the Cheyne-Stokes respiration. Other symptoms are due to cerebral anæmia. The memory is impaired, the patient becomes wayward and irritable, and is apt to become faint upon suddenly changing from the recumbent to the erect posture, and in most instances is incapable of concentrated mental effort or active bodily exertion.

The Blood-vessels.—Capillary dilatation is one of the earliest and most persistent effects of alcohol. The visceral congestions which constitute so important a factor in the pathology of alcoholism are in part the result of the paralyzing action of alcohol on the vaso-motor system, and in part of the degenerative changes in the unstriped muscular fibres of the arterial walls.

Atheroma.—Alcoholic excesses play an important part in the etiology of atheromatous degeneration of the arterial walls, not so much by the direct action of the alcohol itself, as by its indirect action in increasing the tension in the main trunks, and in leading to an irregular life in which excitement, sudden and severe exertion, exposure to cold, and depressing influences of all kinds play a part.

Valvular lesions of the heart do not occur as a direct result of the action of alcohol.

e. Disorders of the Genito-urinary Apparatus.—The Kidneys.—Alcohol, as has been shown above, is a diuretic. In large doses it produces renal congestion. Ollivier³⁶ observed acute transient albuminuria resulting from the influence of excessive doses of alcohol.

³⁶ Essai sur les Albuminuries produites par l'Elimination des Substances toxiques, Paris, 1863.

Much difference of opinion exists as to the part played by alcohol in the causation of the various forms of Bright's disease. It was at one time thought that a large proportion of the cases were due to the abuse of this substance. Bright held this view, and Christison attributed from three-fourths to four-fifths of all cases of granular degeneration of the kidneys to the abuse of spirits. The latter considered that not alone in notorious drunkards was this result likely to occur, but even in those accustomed to the moderate daily consumption of spirits with only occasional excesses. This opinion for a long time largely prevailed among English writers. Of late years, however, in consequence partly of the teachings of Anstie and Dickinson, partly of more precise methods of reasoning, the direct causative relation between chronic alcoholism and disease of the kidneys has come to be questioned. Nevertheless, many teachers of authority adhere to the former view. It is, however, more than probable that the action of alcohol is not of itself capable of producing these effects in the absence of other causes, among which are insufficient or improper diet, irregular living, damp dwelling-places, occupations necessitating great or prolonged exposure to cold and wet or such exposure from accidental causes—circumstances to which those who, especially among the poorer classes, are addicted to drink are peculiarly liable. Nor must we overlook the influence of exposure to paludal poison, of lead, and of heredity in the causation of diseases of the kidneys. While alcohol cannot be regarded as the direct exciting cause of acute or chronic nephritis, chronic alcoholism acts as an influence predisposing to the development of these affections in persons otherwise liable to them.

Congestion of the Kidneys.—The general action of alcohol in inducing visceral hyperæmia is aided by its special diuretic action in causing chronic congestion (cyanotic kidney). The kidney is of a dark violet-red hue, slightly enlarged, especially in its transverse diameter, of a consistence firmer than normal, and bleeds freely upon section.

Acute parenchymatous nephritis is of rare occurrence in chronic alcoholism. Of chronic parenchymatous nephritis Bartels³⁷ writes: “I may say that alcoholic excesses, to which the disease is by many attributed, cannot be charged with being the cause of it. None of the cases treated by me occurred in drunkards, and in no instance have I encountered the large white kidney at the autopsies of notorious drinkers, of which I have made a not inconsiderable number during my many years' active hospital service.” The same author in discussing the etiology of chronic interstitial nephritis (contracted kidney) enters a protest against the view which is widespread in England that the abuse of spirituous liquors favors the development of the genuine contracted kidney. He says: “In the first place, among all the patients whom I have treated, three only were brandy-drinkers to any notorious excess, while by far the greater number who were affected with this complaint had lived remarkably abstemious lives. In the second place, throughout my twenty-five years of active service as a hospital physician I have had the most abundant opportunity of watching the consequences of intemperance, both at the bedside and upon the post-mortem table; yet these three cases have hitherto been the only ones in which I have found atrophied kidneys in the bodies of habitual drunkards.” Baer also testifies to the infrequency of contracted kidneys among drunkards.

³⁷ Ziemssen's Cyclopædia of Medicine.

Fürstner detected by very exact testing a trace of albumen in the urine of almost all cases of delirium tremens examined. Its presence was, however, transient, and appeared to be not associated with structural changes in the kidneys.³⁸

³⁸ Berliner klin. Wochenschrift, 1876, No. 28.

Fatty infiltration and fatty degeneration of the kidneys occur in chronic alcoholism, the former as part of the general fat accumulation, the latter as a result of the general nutritive disturbances.

Amyloid degeneration is rare, and can in no case be ascribed to the direct action of alcohol.

Griesinger saw excessive diabetes insipidus follow a prolonged and severe attack of acute alcoholism in a man twenty-eight years old, and terminate fatally in the course of four months. Ebstein attributes the polyuria of acute alcoholism to lesions of the brain.

Glycosuria is rare among drunkards.

The Bladder.—Catarrh of the bladder is not rare in chronic alcoholism, especially in that form originating from excesses in malt liquors. This condition, however, scarcely occurs with sufficient frequency to be regarded as in any sense a symptom of alcoholism.

The Genital Organs.—The subjects of alcoholism are especially prone to sexual disorders of all kinds—a fact to be explained by the influence of alcohol on the imagination, and especially upon the sexual appetite, its debasing effect on the moral sense and upon the judgment, and the indifference to the consequences of exposure which it begets. In the later stages of chronic alcoholism sexual power is apt to be greatly enfeebled or wholly lost. This condition, which is usually attended also by loss of sexual desire, is to be attributed to the action of alcohol upon the nervous system rather than upon the sexual organs themselves. It has nevertheless been established that long-continued alcoholic excesses are apt to be followed by atrophy of the testicles. Lancereaux has described a condition of these organs resembling in all respects senile atrophy. On the other hand, Huss attributed the impotence of alcoholic subjects to loss of nervous tone. In the female, alcoholism produces disturbances of menstruation and premature menopause. Alcoholic excesses are said also to produce a liability to abortion, and Lancereaux has observed atrophy of the ovaries in alcoholic subjects.

2. Disorders of Special Structures.—a. Disorders of the Locomotive Apparatus.—The muscles at large, like the heart, are liable to fatty infiltration and degeneration. Fatty infiltration, frequent at some period in the course of the affection, is apt to be widespread. The muscles are paler than normal, softer in consistence, and streaked with fat. True fatty degeneration is less frequent, and apt to be localized. Here the muscular fibres lose their striation, and present within the myolemma minute fatty deposits in the form of granules. This change is accompanied by atrophy. The symptoms consist in feebleness and difficulty in movement and in locomotion.

Changes in the bones, notably enlargement of and increase in the contents of the medullary canal in the long bones, and arthropathies of various kinds, have been observed in alcoholic subjects.

b. Disorders of the Skin.—Alcohol is a sudorific, and is largely eliminated by the skin. This effect is purely physiological; therefore the moderate and occasional use of alcohol exerts an influence rather favorable than otherwise upon the tegumentary structures, but in repeated excesses it gives rise to more or less cutaneous irritation. The skin, partly for this reason, and partly because it shares in the general disturbance of nutrition, becomes dry, harsh, and scaly; after a time the face, and especially the nose and neighboring parts, assumes in many instances a violaceous hue, the minute superficial cutaneous veins are enlarged, and acne is common. The resulting appearance is almost characteristic of the habits of the individual. Alcoholic subjects frequently suffer from pruritis, urticaria, and eczema. In certain cases the skin, instead of being dry and harsh, is soft and unctuous, and in others, especially in the more advanced cases, it becomes slightly yellow or earthy in hue. Owing in part to changes in the nutrition, and in part to vascular dilatation, the skin of the extremities is not rarely mottled and cyanotic. In certain forms of alcoholism of the nervous system, and particularly in alcoholic paralysis, in which we have to do with multiple peripheral neuritis, the skin of the affected parts, especially that overlying the atrophied muscles, becomes, in consequence of trophic changes, dusky in color and hard, smooth, and glossy. It has been stated that chronic alcoholism is a cause of pellagra, and numerous observations have been advanced in support of this view (Hardy). The excessive rarity of this condition in countries in which the abuse of alcohol is most common renders it probable that the occasional association of these affections is accidental rather than causal. Chronic alcoholism predisposes to gangrene of the skin and to bed-sores; slight wounds readily inflame and are slow to heal; alcoholic subjects are especially predisposed to erysipelas, while the enfeeblement of the circulation and the lowered tone in the later stages of chronic alcoholism often result in œdema of the inferior extremities.

3. General Disorders.—In addition to the various local disorders thus far described, the prolonged excessive indulgence in alcohol leads to profound disturbances of the processes of nutrition, which are manifested in alterations in the blood, in excessive accumulation of fat, and in a well-marked cachexia.

a. The Blood.—The alterations in the blood, although sufficiently manifest in disorders of nutrition, have not yet been studied with satisfactory results. In chronic alcoholism the proportion of water is increased, while that of fibrin is diminished. After death the blood remains fluid. The red globules are diminished in number. The blood also contains free fat, to which it owes its pale, opalescent, and sometimes almost milky hue. The presence of fat has been demonstrated after the injection of alcohol into the veins of animals.

b. Obesity.—Fat-infiltration and fat-accumulation must be regarded as among the most characteristic disturbances produced by alcohol. Fat is abundantly stored up in the subcutaneous tissues. The anterior abdominal wall is especially liable to its accumulation. The heart, kidneys, omentum, and mesenteries are also not infrequently the seat of abnormally large accumulations of fat. Fat also collects in the muscles and in the intermuscular planes, but to a less extent. Obesity is not, however, so frequent in the advanced stages of alcoholism as it is while the subject has not yet lost the appearance of health, and in a large proportion of the individuals it does not manifest itself at all. It appears to depend largely upon the character of the drink, and is especially frequent among those addicted to excesses in beer. It is less common among wine-drinkers, and relatively infrequent and of moderate degree in those who confine themselves to spirits. A sedentary life, and perhaps also an hereditary tendency, exerts an important influence upon the development of obesity in alcoholism.

c. Alcoholic Cachexia.—The action of alcohol in excessive amounts upon the nutrition of the body at large, and in particular upon the nutrition of the nervous system, is radically unfavorable. This unfavorable influence manifests itself from the beginning, while the subject yet presents the appearance of health, and long before the occurrence of either the symptoms or physical signs of organic disease. The powers of resistance to unfavorable influences of all kinds are diminished; the ability to endure hardships, privations, and fatigue is lessened; sickness and injuries are badly borne; complications are frequent and grave; and convalescence is apt to be tardy and insecure. It is among the more striking peculiarities of the alcoholic subject that blood-losses are badly borne and slowly repaired. It is this want of tone, often latent for a long time under ordinary circumstances, which unfits those addicted to alcohol for Arctic and exploring expeditions and for military and scientific enterprises involving prolonged hardship and exposure. In the course of time disorders of the digestion, of hæmatosis, of circulation, increase the difficulty and render it more apparent. The fat now rapidly diminishes; anæmia develops; the complexion becomes dull, earthy, or slightly jaundiced, the tissues flabby. Then follow diarrhœa, hemorrhages from mucous surfaces, serous effusions, visceral congestions of high degree, hypostasis, œdema, and progressive deterioration of all the powers alike of the body and the mind until the dyscrasia is complete.

The subjects of chronic alcoholism are especially prone to affections of the respiratory tract and to the infectious diseases. They furnish, as a rule, the earliest victims in epidemics. They not rarely die of pneumonia. They develop troublesome delirium in simple maladies, and in all acute affections the prognosis is unfavorable as compared with that in persons of sober habits. As Clouston well says, “The whole organism suffers sanative and mental lowering, alteration of functions and of energizing.”

B. DERANGEMENTS OF THE NERVOUS SYSTEM: CEREBRO-SPINAL DISORDERS.—The disorders of the central nervous system in chronic alcoholism are even more numerous and more important than those already described. Many transient and permanent disturbances of function occur without anatomical lesions recognizable by existing methods of examination; many others are associated with readily-discoverable changes of structure. These changes are encountered in the blood-vessels, the meninges, the substance of the cerebro-spinal axis, and in the peripheral nerves. Much as they differ in appearance and in their clinical manifestations, they may all be referred to three processes: (a) congestion and inflammation; (b) sclerosis; and (c) stentosis.

1. Cerebral Disorders.—The Cranium.—The bones of the skull are often thicker and more dense than normal. This change implicates the diploë and the outer and inner tables. The last is then deeply channelled for the blood-vessels and deeply indented for the Pacchionian bodies, which are commonly hypertrophied.

The Vessels.—Disturbances of the cerebral circulation are among the earliest and most important symptoms. Due primarily to the increased action of the heart and vaso-motor dilatation of the blood-vessels excited by repeated large amounts of alcohol, and secondarily to permanent enlargement of the vessels in consequence of fatty or atheromatous degeneration of their walls, some degree of active or passive congestion is almost always present. It is probable also that in consequence of irregular and complex disturbances of the circulation secondary localized ischæmia occurs. Lentz states that anæmia is more common in the cerebral substance than in the membranes.

The capillaries are usually much altered—sometimes uniformly dilated to a considerable extent, sometimes forming capillary aneurisms. They are more sinuous than normal, their walls show evidences of fatty degeneration, and they sometimes contain minute thrombi. Extravasated blood, in the form of circumscribed collections, of diffuse layers, or finally of capillary hemorrhages, also occurs. These collections are sometimes free, sometimes encysted.

The Meninges.—The dura mater is congested; occasionally it shows more or less extensive areas of inflammation with exudation of lymph. Purulent exudation in the absence of traumatism is rare. The lymph may be deposited in the form of patches of varying extent, or it may form more or less extensive false membranes. These accumulations are of variable, often considerable, thickness, and constitute the condition described as pachymeningitis hæmorrhagica interna, or, from the large amount of blood which they contain, hæmatoma of the cerebral meninges. They occupy the convexity of the brain, and are developed upon the inner surface of the dura; they are usually nearly symmetrical in outline, but of different thickness upon the two sides. They consist of superimposed layers of lymph, between which, or within the substance of which, are more or less extensive blood-extravasations, either fluid, coagulated, or undergoing resorption. More frequently the exudation consists of mere shreds of lymph within the cavity of the arachnoid.

The arachnoid is almost invariably altered. Upon the convex surface of the hemispheres, especially along the median fissure, it is thickened and opaque. This condition may be uniform or distributed in patches, and is apt to follow the line of the blood-vessels.

The pia mater is congested, often œdematous, not rarely the seat of blood-effusions of greater or less extent.

The cerebro-spinal fluid is usually more abundant than normal, of a deeper color, cloudy, sometimes tinged with the coloring matter of the blood.

The Brain.—The intimate lesions of the substance of the brain are not yet known. The volume of the encephalon, as a rule, undergoes no change. Occasionally it appears to be swollen, and protrudes with some degree of force through the incision first made in the membranes. More commonly, the brain is throughout or in certain parts atrophied or shrivelled, its convolutions flattened, its surface retracted. This is sometimes the result of the pressure of collections of hemorrhagic or inflammatory products.

The consistence of the cerebral mass is sometimes increased; it becomes harder, more resistant to pressure, and preserves its form when removed from the cranium better than the normal brain. This condition may be present throughout the brain or it may be localized. In the latter case it is usually due to patches of sclerosis. Softening in more or less extensive areas may occur in the advanced stages of the more severe forms of chronic alcoholism. It is found chiefly in the gray substance, where the vessels are more numerous, especially in the cortex and central ganglia. In this as in other affections cerebral softening is the result of obstruction of the circulation in consequence of atheroma, thrombosis, or other change in the arteries. It varies from simple diminution in consistency to diffluence.

The nervous substance of the brain doubtless undergoes changes proportionate to the degree and duration of its exposure to an alcohol-charged blood. What these changes are has not yet been fully determined. The nerve-cells of the cortex have been found rounded and contracted, so that instead of being surrounded by a small lymph-space they seem to be lying in large cavities, and so granular that the nucleus can hardly be made out. Slight increase in the number of the small round cells in the cortex and in the adjoining parts of the white matter has also been observed (Hun). These changes are not, however, constant. Not only has the microscopical morbid anatomy of the lesions of nerve-substance peculiar to chronic alcoholism not yet been worked out, but even macroscopic changes adequate to account for symptoms that were during life serious, persistent, and apparently referable to well-defined lesions, are sometimes absent altogether.

It is important to distinguish the disorders due to the direct action of alcohol, which are often functional or dependent upon lesions too subtle for recognition, from those which are secondary and dependent for the most part upon coarser changes of structure.

In consequence of hyperæmia of the brain and its membranes there not infrequently occur a sense of confusion or dulness, increasing to headache, which may become almost unbearable, mental disturbances of the most varied character, disorders of movement and sensation, and disorders of the special senses.

Cerebral hemorrhage, to which the subjects of chronic alcoholism are, in consequence of the vascular lesions already described, peculiarly prone, manifests itself by the usual primary and secondary phenomena. Meningeal hemorrhage, save in the form of hæmatoma, is rare except in the advanced stages of paretic dementia.

The blood in alcoholic dyscrasia undergoes changes which favor its transudation through the walls of the vessels; hence a tendency to œdema and to accumulations in serous sacs. This tendency implicates the structures of the nervous system in common with the organism at large. The ventricles of the brain become distended with fluid, and the brain-substance itself and the meninges not rarely become œdematous in the last stage of chronic alcoholism, in consequence of grave disturbances of the circulation or as complications of affections of the lungs, heart, or kidneys. These conditions are attended by mental obscuration, somnolence alternating with sleeplessness, delirium, maniacal paroxysms, impairment of muscular power, of general and special sensibility, impaired reflexes, inability to speak, deepening stupor, and death.

2. Spinal Disorders.—Lesions of the spinal cord or its membranes have been rarely discovered. When present they have been invariably associated with similar or corresponding lesions of the brain or its envelopes. Leyden³⁹ states that not only do the cerebral meninges present inflammatory changes in chronic alcoholism, but the meninges of the cord are sometimes found in an analogous condition; that pachymeningitis hæmorrhagica interna spinalis has also been observed, as well as other forms of spinal meningitis, with thickening and discoloration of the pia and dura; and that œdema of the pia has been especially noted. While anatomical lesions of the cord are less frequent than lesions of the brain, nutritive and functional disturbances, as manifested in the general symptomatology, are quite as common in one as in the other.

3. Disorders of the Peripheral Nerves.—Magnus Huss found no change in the peripheral nerves in five cases in which they were carefully examined. Lancereaux discovered degenerative changes in the peripheral filaments in alcoholic paralysis. Leudet found hypertrophy of the neurilemma and alterations in the cubital nerve in an individual suffering from chronic alcoholism in whom this nerve was paralyzed. Dejerine⁴⁰ observed in two fatal cases of alcoholic paralysis neuritis of peripheral nerves with integrity of the nerve-roots, the spinal ganglia, and the cord. In one of Dreschfeld's cases of alcoholic paralysis,⁴¹ in which the cord was found perfectly normal, the “sciatic appeared thin and grayish, and was surrounded by a great deal of adipose tissue. Vertical sections showed, when treated with perosmic acid and stained afterward with picro-carmine, a moniliform appearance of the nerve-tubes, due to breaking up of the myelin; the nuclei were increased, and there was also some interstitial cell-infiltration. Transverse sections showed in some few places an increase in the diameter of the axis-cylinder, and again the interstitial infiltration.”

Disorders of General Sensibility.—Disorders of general sensibility are among the earliest of the nervous phenomena of chronic alcoholism. They occur in the following order: hyperæsthesia, dysæsthesia, and anæsthesia. Disturbances of sensibility manifest themselves, quite independently of hallucinations, as sensations of malaise, of discomfort, of chilliness, of cramps, or of abnormal warmth or cold. Sometimes they amount merely to momentary discomfort, at other times to extreme pain. They are usually limited, often to the feet and legs, sometimes to the hands and arms; again, they are experienced in the trunk, and especially in the back. They are most common during the evening; less frequently they are induced by the warmth of the bed; and, again, they are experienced on rising. They are apt to be associated with occipital or frontal headache.

Among the most frequent nervous phenomena of chronic alcoholism are disturbances of sleep. Sleep is light, uneasy, and disturbed, difficult to obtain, troubled with dreams, and unrefreshing. More or less complete insomnia is by no means rare. It is more apt to occur, however, after acute exacerbations of alcoholism than in the ordinary chronic condition.

Hyperæsthesia manifests itself as an increased sensibility to pain, to mere contact, to temperature, and in an exaggeration of the muscular sense. Two general forms may be distinguished—the superficial and deep. The former usually manifests itself by an exaggerated sensibility of the skin, especially along the course of the superficial nerves and at their points of emergence from the deeper structures. The latter consists in a more or less intense sensation of pain, often diffuse, sometimes almost unbearable, and associated with a sensation of heat or cold, which is most commonly experienced in the lower extremities. It is often referred by the patient to the deeper muscles or to the bones and joints, and is increased by movement or pressure.

Anæsthesia is a much more common occurrence. It is usually developed during the later period of chronic alcoholism, and may implicate the skin, the mucous tissues, or the deeper structures. It presents all degrees from mere impairment to absolute loss of sensation. In the latter case, contact, pain, temperature, and electrical stimulation equally fail to excite sensation. In the deep anæsthesia of alcoholism pressure and electro-muscular sensibility are alike impaired. The muscular sense is also enfeebled or abolished. The regions which are the seat of anæsthesia are, as a rule, of a lower temperature than those in which sensation is normal. The anæsthesia may extend to the conjunctiva, and even to the cornea and to the mucous membrane of the mouth and throat. It has also been observed in the mucous membrane of the genitalia and at the verge of the anus.

Disorders of Motion.—Disorders of motion consist of tremor, subsultus, spasm, convulsions, muscular paresis, and palsies. Tremor is a very frequent phenomenon in chronic alcoholism. It consists generally of a series of rapid rhythmical movements. Sometimes the extent of the movement is increased and their rhythm irregular. They are then choreiform. The tremor may be continuous; much more frequently it only appears in the morning. The subject has then some difficulty in dressing himself, particularly in buttoning his clothing, in shaving himself, and in raising a cup to his lips. This symptom commonly ceases after the ingestion of a certain quantity of alcohol, only to return on the following morning or after a considerable period of abstinence. Voluntary movements intensify the tremor. It most commonly affects the upper extremities, next in frequency the muscles of the face, and finally the lower extremities. In rare cases it affects the muscles of the whole body. Alcoholic tremor affecting the hands and arms renders the subject awkward and interferes with his ability to work; affecting the lower extremities, it gives rise to an embarrassing, irregular gait; affecting the lips and tongue, it produces hesitation of speech or stammering, and when it is of a high degree articulation may be so imperfect that conversation is impossible; affecting the muscles of the eyes, it gives rise to nystagmus. Tremor is not infrequently associated with subsultus tendinum, spasmodic contractions, and cramps. These phenomena are usually localized, and affect by preference the muscles of the face and those of the lower extremities.

Loss of muscular power, which may pass, little by little, into complete palsy, also occurs. It is, however, neither constant nor proportionate to the gravity of the case in other respects. Whilst, as a rule, it is developed insidiously, it occasionally shows itself with suddenness. In the latter case it is usually preceded by some acute complication, and may disappear as quickly as it came. At first it is a mere feebleness, which, beginning in the fingers, extends to the hands and arms. It may after a time manifest itself in the feet. More or less muscular paresis is invariably associated with the tremor above described.

Alcoholic Paralysis.—The earliest account of alcoholic paralysis is that of James Jackson,⁴² who designated the disease, from its most prominent symptom, arthrodynia. He attributes it to ardent spirits, and chiefly observed it among women. “This arthrodynia comes on gradually. It commences with pain in the lower limbs, and especially in the feet, and afterward extends to the hands and arms. The hands may be affected first in some instances, but in all cases in the advanced stage of the disease the pain is more severe in the feet and hands than in the upper limbs. The pain is excruciating, and varies in degree at different times. It is accompanied by a distressing feeling of numbness. After the disease has continued a short time there take place some contraction of the fingers and toes and inability to use these parts freely. At length the hands and feet become nearly useless. The flexor muscles manifest, as in other diseases, greater power than the extensors, and the whole body diminishes in size, unless it be the abdomen; but the face does not exhibit the appearance of emaciation common to many visceral diseases. The diminution is especially observable in the feet and hands. At some time the skin of these parts acquires a peculiar appearance. The same appearance is noticed in a slighter degree in the skin of other parts. This appearance consists in great smoothness and shining, with a sort of fineness of the skin. The integument looks as if tight and stretched, without rugæ or wrinkles—somewhat as when adjacent parts are swollen. The skin is not discolored. In this disease there is not any effusion under the skin, and the character which it assumes arises from some change in the organ itself.”

Since Jackson's day, Huss, Lancereaux, Leudet, and others have described various forms of paralysis due to alcohol. Wilks⁴³ under the term alcoholic paraplegia described a form of alcoholic paralysis of which he had seen numerous cases, especially in women addicted to alcoholic excesses. The symptoms are severe pain in the limbs, especially the lower ones, with wasting, numbness, anæsthesia, only slight power of movement or total inability to stand. The symptoms are not unlike those of ataxia. Wilks regarded the disease as due to degeneration of the cord and thickening of the membranes. Several of the cases terminated in recovery in a comparatively short time after the abrupt and complete withdrawal of alcohol. Since that time a number of cases have been reported by various observers.⁴⁴

⁴³ Lancet, 1872, vol. i. p. 320.

⁴⁴ See, in particular, Hun, American Journal of the Medical Sciences, April, 1885, “Alcoholic Paralysis.” This paper contains a valuable résumé of the reported cases up to that time. Consult also Dreschfeld, Brain, July, 1884, and January, 1886.

Hun concludes that alcoholic paralysis may be regarded as a special form of disease with the following symptoms: “Neuralgic pains and paræsthesiæ of the legs, gradually extending to the upper extremities, and accompanied at first by hyperæsthesia, later by anæsthesia, and in severe cases by retardation of the conduction of pain. Along with these symptoms appears muscular weakness, which steadily increases to an extreme degree of paralysis, and is accompanied by rapid atrophy and great sensibility of the muscles to pressure and to passive motion. Both the sensory and motor disturbances are symmetrically distributed. The paralysis attacks especially the extensor muscles. In addition to these motor and sensory symptoms, there is also a decided degree of ataxia. The tendon reflexes are abolished, and vaso-motor symptoms, as œdema, congestion, etc., are usually present. Symptoms of mental disturbance are always present in the form of loss of memory or transient delirium.”

Lesions of the cord are absent, but degenerative processes in the peripheral nerves have been discovered in a number of cases. The symptoms are those of multiple neuritis, and the essential lesions consist in degenerative changes in the peripheral nerve-fibres. The associated mental derangement, tremor, and ataxia have been ascribed to changes in the cerebral cortex.

Dreschfeld has divided the cases, according to the more prominent symptoms, into two clinical groups—alcoholic ataxia and alcoholic paralysis.

The ataxic form represents a milder type. The symptoms are lancinating and shooting pains in the lower extremities, sometimes in the upper, with areas of anæsthesia and retarded sensibility. The muscles are painful upon pressure, and atrophy may be moderate or absent altogether. Inco-ordination is marked. The tendon reflexes are absent. Shooting pains down the legs to the toes of a paroxysmal character, and followed by a sense of numbness, also occur. Eye symptoms are wanting.

The paralytic form is usually associated with atrophy, affecting chiefly the extensors of the fingers and toes. The paralysis and atrophy in some cases come on acutely, in others more slowly. When the patients come under observation they are usually unable to stand or walk, and it is therefore not easy to make out whether or not the paralytic stage has been preceded by a stage of ataxia. As the sensory phenomena in these cases are the same as in the first group, it is probable that pseudo-ataxic symptoms have preceded the slowly oncoming paralysis. Paralysis and atrophy of the extensors of the fingers and toes, with paresis of the other muscles, are associated with the sensory phenomena above described. Tendon reflexes are absent; the superficial reflexes are much diminished. Recovery takes place in a considerable proportion of the cases upon the withdrawal of alcohol. The atrophy and paralysis pass away altogether, the tendon reflexes are restored, and the disturbances of sensation disappear. In the greater number of these cases persistent delusions are present.

Lancereaux⁴⁵ describes alcoholic paralysis as symmetrical, affecting either the upper or lower extremities and gradually extending toward the trunk. The lower extremities are invariably more affected than the upper, and the extensor than the flexor muscles. There is diminished reaction to electricity, and anæsthesia is present. The brain and spinal cord are normal, but the peripheral nerves show extensive degenerative changes.

4. Disorders of the Special Senses.—a. The Sight.—Disorders of vision are among the most frequent and the earliest symptoms of chronic alcoholism. Phosphenes, scintillations, sensations of dazzling, muscæ volitantes, and streams of light are often complained of. These phenomena may be constant or transient. Diplopia and other visual disturbances of the most irregular and annoying character also occur. Sometimes there is dyschromatopsia; the colors are confounded: red appears brown or black, and green appears gray, etc. In the more advanced stages amblyopia may occur. The acuity of vision rapidly diminishes, sometimes to the point that the patient with difficulty distinguishes the largest print. Objects appear as seen through a fog, and their outlines are distinguished only after repeated and close effort. Again, blindness almost absolute occurs for the course of some minutes—passes away rapidly, only to return again at intervals. Not infrequently the sight is better in the morning and evening than during the day. Achromatopsia, characterized by enfeeblement, and not infrequently by the momentary loss of the power to recognize colors, and particularly the secondary tints, also occurs. Cases of Daltonism occasionally seem to depend, to some extent at least, upon alcoholic disturbances of vision. Impairment of the power to distinguish colors must not, however, be confounded with the difficulty experienced by many alcoholic subjects in recognizing different colors successively presented to the eye with some degree of rapidity. Such individuals are able to distinguish colors when sufficient time is permitted them. Their difficulty depends upon tardiness of perception, such as is often experienced by neurasthenic subjects in recognizing faces in a crowd, rather than upon any failure in the power of recognizing colors. As a rule, the disorders of vision are not permanent, at least in the beginning. Later, they are of longer duration, and alcoholic amblyopia occasionally degenerates into irremediable amaurosis. Ophthalmoscopic examination reveals at first no appreciable lesion, and the disturbance of circulation, venous stasis, and peri-papillary infiltration thus observed appear to be inadequate to explain the visual disturbance. Atrophy of the optic nerve occasionally occurs as a direct result of alcoholism. Nystagmus has been frequently observed. The state of the pupils is variable and without constant relation to the acuity of vision. The pupils are not infrequently uniformly dilated, contracting slowly under the influence of light. More rarely they are permanently contracted; occasionally they are unequal. These modifications are often without demonstrable relation to anatomical lesions.⁴⁶
