~Dietetic Treatment~ in diphtheria is most important. It consists of a fluid diet made up of milk, malted milk, or buttermilk. At times the condition of the throat makes a slightly thickened mixture more easily swallowed than one which is distinctly fluid in character, and for this purpose farina, arrowroot, or barley flour may be used. ~Increasing the Diet.~--As convalescence advances the semi-solids, soft toast, soft custards, gelatin, and cereals may be given. Should the heart show symptoms of being affected, the intake of fluid must be restricted. ~Gavage and Rectal Feeding~ are at times necessary. Infants may be successfully fed by passing a small rubber tube through the nose into the stomach and administering the milk formula to which they are accustomed. Rectal feeding is likewise valuable in cases of extreme anemia accompanying diphtheria. Care must be observed by the nurse in giving gavage to babies, since any struggling on the part of the child may result in death from heart disease. ~Whooping Cough.~--On account of the character of the disease and the proneness of the stomach to eject the food during paroxysms of coughing, dietary measures are more or less necessary in order to enable the child to receive sufficient food to cover his daily needs. ~Complications.~--Hemorrhage, pneumonia, albuminuria, diarrhea, and convulsions may occur during the disease, while tuberculosis and chronic bronchitis may follow as after-effects. ~Dietetic Treatment.~--Breast milk is by far the best food for the baby, in this as in all conditions. In whooping cough the fact that this fluid leaves the stomach almost as soon as it enters lessens the chances of the baby losing its meal by vomiting it. ~Older children~ do well with frequent small meals, since they are not so apt to give rise to pressure which brings on the paroxysms of coughing and vomiting. When the meal is vomited, a second should be given in order to keep the child from suffering from malnutrition. ~Stimulation~ is found to be necessary in certain cases. Albumen water containing a spoonful of brandy or some of the prepared beef preparations, such as liquid peptonoids, may prove valuable under the circumstances. ~Measles.~--Complications and after-effects developing as a result of measles make the dietetic treatment of this disease important. Gastro-intestinal disturbances, especially diarrhea, are apt to occur, and tuberculosis has been known to develop as a result of measles. ~Dietetic Treatment.~--The fluid diet as used in any acute febrile condition is used as long as the temperature is elevated. Milk, buttermilk, malted milk, and milk soups constitute the chief items in the diet. Orangeade and lemonade are found valuable in relieving the thirst.
