After three weeks, if the patient shows no disposition toward nephritis, and if convalescence is progressing satisfactorily, the diet may be increased day by day, adding milk toast, cereals, cream soups, rice, baked potato, then custards and soft eggs, the soft part of oysters, broiled or baked fish, broiled breast of chicken, and, still later, rare beef and lamb chops. Meat, however, must not be given until all danger from nephritis has passed.
DIPHTHERIA
Diphtheria.—The feeding in diphtheria follows the régime given in acute fevers. The body must be kept in good condition. At the same time it is necessary to understand the complications which make the dietetic treatment of this disease assume a place of importance.
Complications.—It may be complicated by broncho-pneumonia, albuminuria, carditis, endocarditis, and dilatation of the heart. Anemia must be combated, but care should be used not to push the diet to such an extent as to impose too great a tax upon the already weakened heart.
Dietetic Treatment.—While the fever lasts the diet must be fluid, milk, buttermilk, malted milk, and some of the proprietary infant foods such as Mellin’s Food, Eskay’s Food, and like preparations. Milk gruels, made with milk and some cereal such as farina, barley flour, fine cornmeal, arrowroot, strained oatmeal, etc., are at times more easily swallowed than the unthickened liquids. Liquid beef peptonoids, panopeptone, and like predigested beef preparations prove valuable in many cases.
Convalescent Diet.—As convalescence progresses, or in cases where the patient finds it easier to swallow a semi-solid than a liquid, soft custards, gelatin, well-cooked cereals, and ice cream may be given. Eggnog and milk punch are at times given, but only upon the advice of the physician in charge.
Rectal Feeding.—When the condition of the patient makes it necessary to nourish in other ways than by mouth, nutrient enemas[89] may be given. In certain cases of diphtheria, young infants can be fed more successfully through a tube inserted by way of the nose into the stomach than by feeding in the ordinary way. The formula is prepared in the same way as for bottle feeding, and is poured into a glass funnel and through the soft rubber catheter into the stomach. Care must be observed to prevent the patient struggling on account of the heart weakness which invariably complicates this disease.
WHOOPING COUGH
In the early months of life it is probable that whooping cough is one of, if not the most fatal of the diseases to which the infant is subjected. The period of incubation of this disease is from one to two weeks, the cough at first not appearing different from those accompanying colds of all sorts. However, in from ten days to two weeks the characteristic whoop occurs, differentiating this disease from all others. The symptoms aside from the whoop are the difficulty of taking breath and the great prostration after the paroxysm and the frequent vomiting of the food, brought on by the violent coughing.
In very young infants the whoop does not always occur. But the child coughs and holds its breath until it is blue in the face. At times young babies may have convulsions. The so-called spasmodic stage, during which the child may have from a few to a great number of paroxysms of coughing a day, lasts from a month to six weeks, and in some cases even longer. As the disease declines the cough gradually disappears and the child appears to be suffering with ordinary bronchitis. The characteristic whoop may return at any time during the ensuing six months or year if the child has an attack of bronchitis and is inclined to cough.
