Part 73

Metallic preparations are of use in some cases. If for any reason they are preferred, the perchloride of iron is one of the very best preparations. Arsenic and zinc may also be tried in small doses.

Pepsin and its Uses.--Of the efficacy of pepsin as an artificial substitute for the normal solvent of the food adverse opinions have been expressed, but in spite of the most critical scepticism as to its action its use since first introduced into medicine has steadily increased. It has been shown to be the natural constituent of the gastric juice and glands, and as a natural ferment, when combined with hydrochloric acid, it constitutes the most important solvent of the nitrogenous portions of our diet (Habershon). There is a vast number of different preparations of pepsin in the market, and some of them are doubtless of little value. We ought to be quite sure that the article is what it purports to be. The pepsina porce is the best preparation, one grain of which, says Beale, ought to thoroughly digest one hundred grains of boiled white of egg in three or four hours at a temperature of 100° F. His test as to the value of pepsin is as follows: "One hundred grains of hard-boiled white of egg, cut into thin slices, may be placed in a wide-mouthed bottle or flask with one ounce of water and twenty drops of dilute hydrochloric acid. One {457} grain of pepsin powder is to be added, and the mixture placed before a fire at a temperature of about 100° F. The flask is to be shaken from time to time. In about an hour the white of egg begins to look transparent at the edges, and in about four hours it will be completely dissolved if the pepsin is good." In cases of feeble digestion from deficiency of gastric juice pepsin is a valuable adjuvant to the digestive power, and may be given with advantage in connection with the mineral acids or with ipecacuanha or capsicum before meals.

Special Remedies.--There are certain symptoms characteristic of the different forms and complications of dyspepsia that require special remedies. Bismuth is often useful. It is especially indicated where there is a morbid painful condition of the gastric nerves. The subnitrate or carbonate of bismuth may be given in ten- or twenty-grain doses, suspended in water by means of mucilage of acacia, and flavored with ginger or peppermint. It should always be given on an empty stomach. Other elegant preparations supposed to be improvements upon these have been recommended, and may be tried.

In cases of anæmia, if there are no contraindications, iron may be tried. If digested and assimilated, it improves the blood, and this is often the first step in the direction of restoring functional activity. Of the preparations of iron, none is perhaps superior to the perchloride. The saccharo-carbonate and the ammonio-citrate are also valuable and unirritating salts of iron, and may be given with other tonics. Ferruginous mineral waters slightly charged with carbonic acid are well tolerated in small doses. The free dilution favors the action, and is frequently more acceptable to the stomach than the more concentrated forms. From one-half to one glassful may be taken at a time; and the use of iron in this form may be preceded or accompanied by the administration of small doses of quinia and of the bitter tonics. But it is a mistake to commence the treatment by the indiscriminate use of iron, quinine, and nerve-tonics. The contraindications to the use of iron are irritable and inflammatory states of the mucous membrane, or dyspepsia associated with deranged conditions of secretion, as manifested by dirty tongue and loaded urine.

When the nervous system is prominently at fault, nux vomica, arsenic, and the nitrate and oxide of silver often prove to be valuable remedies. Here also benefit may be derived from the lighter ferruginous preparations; indeed, few combinations have greater influence over the nervous system than the joint action of arsenic and iron. Much benefit may also be derived, in special cases, from methodical hydro-therapeutic treatment. If judiciously used it strengthens the nervous system, stimulates the organic functions, and increases the power of vital resistance. And in some cases of nervous dyspepsia electricity gives good results. In all cases of nervous prostration as much wholesome food should be taken as the stomach can easily digest.

In hepatic forms of indigestion there is no substitute for an occasional mercurial cathartic, for, notwithstanding adverse criticism, clinical experience has taught the great value of this drug upon the upper portion of the intestinal track. The mode of operation may be doubtful, but the result is unquestionable. In functional disturbance of the liver or morbid conditions of the upper portion of the intestinal track, as indicated {458} by the loaded tongue, sallow complexion, want of appetite, and lithæmia, no remedy will give so much relief as a few broken doses of calomel, followed by a saline aperient; or eight or ten grains of blue mass, with a grain of ipecacuanha, may be administered at bedtime, followed by a saline draught in the morning. After the bowels are thoroughly unloaded by a mercurial, great advantage may be derived from a systematic course of the aperient mineral waters--the Friedrichshall, the Hunyadi, Carlsbad, or some of the mineral waters of our own country. The hepatic form of indigestion cannot be relieved until we relieve the congested hepatic portal system, and this is best accomplished by the general line of treatment here indicated. The simple vegetable bitters, with or without alkalies, may be used at the same time or subsequent to this treatment; but they are often worse than useless until we secure freedom of abdominal circulation. The diet should be light and nourishing, and the patient should spend most of his time out of doors. Horseback exercise is peculiarly advantageous.

But in many cases of the more chronic forms of dyspepsia the colon is as atonic as the stomach, and therefore the bowels require special attention. In colonic dyspepsia all active purgation should be avoided, and salines, such as sulphate of magnesia, the Hunyadi and other saline mineral waters, should be specially prohibited. The most useful aperients in such cases are rhubarb, aloes, senna, colocynth, or podophyllin. Few laxatives answer a better purpose than the ordinary compound rhubarb pill. It may be improved, in special cases, by combining with it extract of nux vomica or belladonna. When there is no affection of the rectum to forbid its use, the watery extract of aloes answers very well, and, unlike many cathartic substances, the dose need not be increased, nor does it disturb the digestive process. It may be given in one-sixth of a grain up to a grain or more, and its purgative action may be improved by being reduced to a state of very minute division and combining with it small doses of belladonna. Belladonna itself is a useful remedy. According to the observations of Harley, it "tones and tightens the longitudinal fibre, while it relaxes the circular;" and long before this theory of its action was suggested, Trousseau called attention to its singular efficacy in producing easy and natural evacuations from the bowels. It is important to observe its mode of use. It should be given in sixth of a grain doses of the extract in the morning a half hour or hour before breakfast. Its efficacy may be increased by combining with it small doses of the watery extract of aloes. In colicky conditions of the bowels two- or three-drop doses of tincture of colocynth sometimes act wonderfully well. In obstinate constipation the free use of diluents at the termination of digestion is often attended with excellent results. But the hygienic and dietetic treatment of constipation is even more important than the medicinal, such as outdoor exercise, the cold bath, rubbing, kneading the bowels, and the use of bread made of whole meal, oatmeal, and an abundant supply of fresh vegetables and fruits.

Nausea and vomiting, occasional symptoms of functional dyspepsia, may be relieved by various agents, such as effervescing draughts, lime-water, oxalate of cerium, hydrocyanic acid, creasote, ice, and alkalies.

When vomiting is dependent on fermentation or putrid action of the contents of the stomach with development of sarcinæ, it may be checked {459} by carbolic acid or by creasote, or by the sulphite of soda or sulphurous acid; and in irritable conditions of the stomach bismuth is a valuable remedy. It may be given with alkalies or with finely-triturated animal charcoal.

Gastric pain needs treatment appropriate to the circumstances under which it arises. Sometimes it is relieved by regulating the ingesta or the intervals at which it is taken; sometimes by warm carminative stimulants or by chloric ether, ginger, or brandy. If the pain is more constant, approaching a condition of gastralgia, hydrocyanic acid and bismuth are more effective remedies. But it cannot be too strongly stated, in conclusion, that in the management of the atonic forms of dyspepsia hygienic treatment is of prime importance. The hopeful future of medicine lies in the direction of promoting healthy nutrition, and this is best accomplished by the careful adaptation of food and exercise and modes of living to individual cases of disease.

Gastralgia (Gastrodynia, Cardialgia, Spasm of the Stomach).

Under the head of neuroses of the stomach have been variously described the conditions indicated in the heading of this section; and a certain amount of confusion has arisen in the use of these terms from the fact that they represent subjective sensations common alike to organic and functional forms of indigestion: pain, for instance, is felt in gastritis, cancer of the stomach, and ulcer of the stomach. Indeed, it rarely occurs independently of some disorder of digestion or structural lesion of the stomach.

By gastralgia, considered as a distinct affection, however, we mean a purely neuralgic condition of the sensory fibres of the stomach, excluding inflammatory and structural changes on the one hand and chronic forms of atonic dyspepsia on the other. The attacks are usually periodical in character, with constricting pain in the pit of the stomach, and the intervals are not necessarily associated with symptoms of dyspepsia. It chiefly occurs in females of nervous temperament at the catamenial periods.

Two forms of the disease have been described--one depending on hyperæsthesia of the sensory fibres of the pneumogastric, the other on hyperæsthesia of the solar plexus. This may be correct in theory, but practically it can be of little importance to make the discrimination, even if it were possible to do so.

Clinically, the disease is presented to us in two forms. In one the pain is agonizing, comes on without premonition, is sometimes intermittent or remittent in character, and conveys to the sufferer the idea of spasm; hence it has often been described as colic of the stomach. If not relieved by appropriate remedies, the pain may last for hours or days. This is the acute form. In the other the pain is more of a neuralgic character and is not so severe. There may be varying exacerbations which may last for months or years. This is not an unfrequent form, and may consist simply in the more acute form becoming chronic.

ETIOLOGY.--With the limitation indicated, we have naturally to seek the causes of the affection, says Ziemssen, in two directions: either in the abnormal nature of the irritants to which the gastric nerves are subjected, {460} or in an altered condition of the nerves themselves, which therefore react abnormally with the normal degree of irritation. This briefly covers the whole ground of the etiological relations of the disease.

The predisposing causes are such as produce general depressed vitality, embracing at the same time special conditions of extreme nervous excitability. Some of these general conditions were pointed out while speaking of atonic forms of dyspepsia. Indeed, the two conditions are often associated, and practically it may be difficult to separate them, although the connection between them is not necessarily an invariable one. Like atonic dyspepsia, gastralgia is apt to affect anæmic persons, and notably anæmic females at menstrual periods. Thus, the association between gastralgia, chlorosis, and hysteria is a matter of common observation. Of 350 cases noted by Briquet, only 30 had no signs of gastralgia; and this observation is a fair average expression of the experience of others.

Certain blood-poisons are also known to give rise to the disease. Infection of the blood by malaria was observed by Niemeyer to produce spasm of the stomach instead of the paroxysms of intermittent fever; and in malarious regions of the United States the same observation has been made. Gout and rheumatism are also known to sustain causative relations to the disease. Certain idiosyncrasies also enter as a factor into the somewhat complex etiology of the disease. Thus, some persons suffer immediately from eating certain kinds of food and fruits, such as shellfish, strawberries, honey, and even milk and coffee. The pain and spasm are produced by direct contact with the sensory fibres of the stomach; i.e. they react abnormally to normal stimulation. But disease of the nerve-centres may enter into the causation. This is seen by the effects of morbid growths impinging upon nerve-trunks; their terminal branches often become extremely irritable and painful, and this condition may be intensified by idiosyncrasy. Excessive acidity of the stomach, seeds of fruit, certain articles of food, the presence of worms in the stomach, and draughts of ice-water may simply act as exciting causes to a centric predisposition.

Of the more direct causes operating upon nerve-centres, all the depressing passions and emotions deserve special mention; so do all causes which produce an exhausted state of innervation, such as venereal excesses, onanism, the abuse of narcotics, etc.

But chief among the causes are those of a reflex kind. Painful affections of the kidneys, irritable conditions of the bladder, diseases of the liver, and, above all, morbid conditions of the female genital organs, sustain a direct and close relation to painful and spasmodic conditions of the stomach. It is a common accompaniment of versions, flexions, prolapses, inflammations, erosions of the os, as well as diseased conditions of the ovaries. When such local conditions are associated with anæmia and hysteria, patients rarely fail to have painful gastric complications.

SYMPTOMS.--The symptoms of gastralgia, like most of the neuroses, are characterized by severe pain occurring in paroxysms, followed by remissions, and sometimes by complete intermissions, again to recur with varying degrees of severity. The pain in the acute variety is of a violent, spasmodic character, and is referred to the epigastrium immediately beneath the ensiform cartilage. Frequently it extends from the epigastrium to the back and chest and into the right and left hypochondrium. {461} No one has so briefly and so accurately described the immediate attack of gastralgia as Romberg: "Suddenly, or after a precedent feeling of pressure, there is severe griping pain in the pit of the stomach, usually extending into the back, with a feeling of faintness, shrunken countenance, cold hands and feet, and small, intermittent pulse. The pain becomes so excessive that the patient cries out. The epigastrium is either puffed out like a ball, or, as is more frequently the case, retracted, with tension of the abdominal walls. There is often pulsation in the epigastrium. External pressure is well borne, and not unfrequently the patient presses the pit of the stomach against some firm substance or compresses it with his hands. Sympathetic pains often occur in the thorax under the sternum, in the oesophageal branches of the pneumogastric, while they are rare on the exterior of the body. The attack lasts from a few minutes to half an hour; then the pain gradually subsides, leaving the patient much exhausted, or else it ceases suddenly with eructation of gas or watery fluid, with vomiting, with a gentle soft perspiration, or with the passage of reddish urine."

Besides the violent paroxysmal pain referred to the stomach, symptoms of derangement of other organs are often present. Prominent among these are hysterical phenomena which are protean in their manifestations, and if not recognized they are liable to mislead. Thus, with gastric pain there may be violent palpitation of the heart, with shortness of breath, cough, globus, hiccough, and convulsive affections, and in a certain proportion of cases there is marked melancholia or hypochondriasis.

The stomach is variously modified in its function. In many cases it is entirely unaffected. The desire for food may be indeed increased, and its ingestion may give a sense of relief. In others vomiting may be severe, while in still others there may be merely a condition of anorexia. The tongue is, as a rule, clean, the skin cool, the temperature undisturbed, and there is absence of tenderness over the epigastrium. Generally pressure relieves the pain.

DIAGNOSIS.--Functional and structural troubles of the stomach very markedly simulate each other; therefore the diagnosis requires to be made with great caution, and this is best done by a most rigid and careful exclusion; and this becomes difficult because the symptoms are mainly subjective.

It is a matter of great moment in differentiating the disease to take into account all constitutional states which predispose to nervous asthenia. Thus in conditions of chlorosis and hysteria the presumption is strong that the pain is neurotic or spasmodic in character; and this presumption is intensified if there be no accompanying constitutional symptoms which indicate inflammatory action. We exclude inflammatory conditions of the stomach by the frequent and complete intermissions, by the absence of thirst, tenderness, and all febrile movement. Moreover, the pain of inflammatory affections, unless produced by corrosive poisons, is rarely so severe as in neuralgic affections; nor are nausea and vomiting so uniformly present in neurotic affections. Then the time at which the pain is experienced is a matter of importance. In inflammatory affections it is felt immediately on taking food. In neurotic affections it may occur when the stomach is empty, and it is not unfrequently relieved by food. In ulcer and cancer of the stomach pain is a common element, and, as in {462} gastralgia, it is referred to the epigastrium. But in gastric ulcer the pain is rarely absent; it is of a dull, gnawing character, is strictly localized in the centre of the epigastrium, and is aggravated by pressure and by food. Moreover, the vomited matter often contains blood. In cancer of the stomach the pain is not as severe and spasmodic in character as in gastralgia, the vomiting is a more prominent symptom, and the material vomited has the characteristic cancerous look. Cancer is more apt to occur too in advanced life, and it is characterized by a steady progressive emaciation.

Gastralgia may also be confounded with rheumatism of the abdominal muscles as well as neuralgia of the inferior intercostal nerves, and it is liable to be confounded with colic resulting from biliary calculi. Colicky pains in the transverse portions of the colon may also be mistaken for pains in the stomach. "It is no exaggeration to say," says Trousseau, "that in perhaps half the cases which are called gastralgia the affection is nothing more than cholalgia." The more fixed the pain is to one spot, and the nearer it is to the median line, the greater is the probability of its being gastric.

PROGNOSIS.--Notwithstanding the severe and apparently alarming nature of the symptoms, the prognosis of gastralgia is in the main favorable, although the prospect of a permanent and speedy cure is small. The duration of the disease depends on the nature and persistence of the exciting causes, and these are so often associated with an exhausted state of innervation that speedy recovery from the disease cannot be promised. In the simpler varieties, caused by improper food, the disease will disappear by removing the cause, and the hysterical forms are liable to disappear with advancing life. So also cases arising from malaria, anæmia, chlorosis, uterine disease, rheumatism, and gout may be relieved by removing the cause. But there are cases produced by unknown causes, and especially cases associated with a general and unexplained cachexia, in which the prognosis is not good.

TREATMENT.--This is both radical and palliative. The radical treatment must have reference to the diseases which have given rise to it. If, for instance, the gastralgia can be traced to sympathetic disturbances of the uterine organs, no remedy can be permanently effective until the cause is removed. Since chlorosis and anæmia are so often found associated with it, benefit may be expected from the ferruginous preparations in some form. Iron occupies a prominent place as a remedial agent. The precipitated carbonate is to be preferred on account of its peculiar influence over the nervous system, and especially over painful neuralgic conditions. It may be given in drachm doses, or even larger, combined with ginger or aromatic powder. If the stomach will not tolerate it, other preparations may be tried.
