The etiology of each case may at once suggest a line of treatment. Among the causes which point to appropriate measures are—the continued presence in the bowel of indigestible or undigested food, constant exposure to cold or to changes of temperature, chronic cardiac disease and portal congestion from any cause, chronic cachexiæ, as syphilis, malaria, tuberculosis, or Bright's disease, the crowding together of individuals in prisons, asylums, etc.
1. The mildest form of intestinal catarrh characterized by intestinal indigestion and constipation or by the passage of fecal matter more or less solid, mixed or coated with mucus, is best treated by a diet such as is advised for intestinal indigestion, bathing with friction, outdoor life, exercise on horseback or by walking, pleasurable occupations, and travel. Iron if there is anæmia, and strychnia if there is a sluggish capillary circulation, with cold hands and feet, are available and useful in many cases. Massage and the Swedish movement treatment find useful application in feeble men and in women who are not strong enough for outdoor exercise. To aid the digestion the liquor pancreaticus as advised by Roberts, a teaspoonful one hour and a half to two hours after each meal, with ten to twenty grains of the bicarbonate of sodium, is, theoretically at least, to be warmly recommended. The Rockbridge alum water, a small glass three times daily between meals, has astringency enough for the hyperæmic membrane and is of good service without increasing constipation.
Purgatives should be avoided as much as possible. An enema of cool water, not more than a tumblerful, taken each morning after breakfast if persevered in, may do all that is needed in this direction. If it fails to empty the bowel completely, a larger enema of warm water—one pint—holding in solution sulphate of zinc or alum in the strength of one grain to three or four ounces, can be thrown high up with a rubber tube once daily. This acts upon the mucous surface, constringes mildly the congested vessels, and when expelled brings away the retained fecal matter. These astringent rectal injections offer promise of cure in many obstinate cases where the colon is chiefly the seat of disease. Belladonna is advised for cases of this kind in combination with strychnia for the constipation. Mild laxatives are often necessary. Bedford mineral water, Hunyadi water, or other salines and the less active vegetable cathartics, can be given alternately. Ipecacuanha has had quite a reputation in combination with purgatives in intestinal catarrh. Aloin pills empty the bowel without much attendant irritation.
2. The form of catarrh which shows itself in a tendency to diarrhoea from indiscretions in diet or from exposure to cold must receive prophylactic treatment. Especially in this form is it important to improve the activity of the skin by bathing and friction, and to lead a temperate life in all things, regulating the diet according to the rules already stated. Tonics are called for in such cases. Fowler's solution of arsenic (one drop before each meal, Ringer), the potassio-tartrate or the tincture of the chloride of iron, dilute sulphuric acid, nitro-muriatic or hydrochloric acid, are efficient in improving digestive activity or in opposing the anæmia which is nearly always present. Quinia is indicated in malarial anæmia with a disposition to loose bowels. Quassia or other vegetable bitters can be given if the appetite is languid; the bitters are, as a rule, of little benefit, and may do harm if diarrhoea exists. Strychnia with quassia or columbo stimulates the appetite and the gastric digestion. When intercurrent attacks of diarrhoea come on with coated tongue, flatulence, distress about the umbilicus after eating, bismuth given on an empty stomach in full doses is serviceable. Small doses of morphia or of opium in some form can be added to the bismuth if there is much pain or when the stools are frequent.
In this and in other forms of intestinal catarrh mineral waters are profitably employed. They are best taken at their sources; and here, as in the case of sea-bathing, the benefit is largely due to the change of air and scene and to the more simple mode of life. Any of the watering-places where alkaline-saline waters or ferruginous waters are found may be of benefit. A trip to Europe and a stay at Carlsbad will break up many an obstinate case of chronic abdominal disorder; but other beneficial waters in Europe are Tarosp, Rohitsch, Marienbad, Kissengen, and Plombières.
In this country the comfort and conveniences of the summer hotels and climate are as much to be considered as the chemical composition of the waters. For milder forms of catarrh with constipation a season at Saratoga, with a life of temperance there, is a wise procedure. Bedford Springs, Pa., offer the same advantages in part, but the waters are best suited to catarrh with constipation. Many of the Virginia springs benefit health-seekers who do not place too much reliance upon the virtues of the waters, and who trust to the value of pure air, exercise, diversion, and rest.
3. All plans of treatment for the more severe form of catarrh with chronic diarrhoea (follicular enteritis) must be based upon a knowledge of the lesions. Bearing in mind the alterations in the mucous and submucous tissues, it is clear that no treatment can be successful which is not carried out with the most careful attention to details, and which is not continued for some time after all the symptoms of the disease have ceased. The complete resolution of hypertrophied glandular tissue, the scattering of cell-accumulations, and the healing of ulcers can only be secured in this way. It is best to present the whole case before the patient, so as to enlist in the task his intelligent co-operation.
Directions for the guidance of cases of this kind must include every detail of the patient's life. The question of residence is of importance to begin with. A cool and dry climate is better than a wet and warm one, and where other means fail change of climate is sometimes the only cure. A sea-voyage, a residence in a mountain-region, will oftentimes promptly and effectually cure an obstinate diarrhoea. House-drainage and ventilation should be examined into and improved. The occupation may have developed the disease; in overwork may lie the origin and the cause of its continuance. Rest from work is therefore in some instances the one thing needed. In all cases the energies and the brain should not be overtaxed. The bath to keep the skin active can be combined with friction. The hot bath, as hot as can be borne, is the best. It is a stimulant, not a depressant, as is the tepid bath, and it is safer than the cold bath.
The cold sitz bath or the application of cold compresses diminishes abdominal plethora, and is wisely advised in strong persons who are not depressed or chilled by external cold. Sea-bathing is another hydro-therapeutic measure which is of unquestioned advantage in all forms of intestinal catarrh.
Permanent baths have been found very serviceable in many chronic diseases, and there are many reasons for advising them in obstinate diarrhoeas. There can be no better means for bringing to bear a strong and continued influence upon the intestinal mucous membrane. The patient should be kept in the warm bath for one, two, or three weeks, according to his strength and the effect upon the disease. Systematic hot bathing under the direction of a physician at Richfield, Sharon, the Hot Springs of Virginia or Arkansas, is an invaluable aid.
