Having thus described in some detail the principles to be followed in all fever cases, it remains now simply to apply these principles to the various infectious diseases. Those diseases which require no special individual dietary and which may be treated dietetically by a simple application of the principles just laid down under the above topic are here named:

Group I

Measles Mumps Malaria Erysipelas Dysentery Scarlet Fever Small-pox Typhus Fever Yellow Fever Relapsing Fever

Dengue

Influenza

Septicemia and Pyemia

Cerebrospinal Meningitis

Pleurisy and Empyema

Laryngitis

Acute Bronchitis

Pneumonia

Acute Articular Rheumatism.

In the case of scarlet fever, named in the above list, milk should remain the staple diet until after the scaling. Inasmuch as most cases of scarlet fever are among children, the milk diet is usually relished and well borne throughout the period. After the scaling the patient may pass rapidly through the course of semi-solid, and after a few days begin the use of solid foods.

In the case of rheumatic fever, i. e., of acute articular rheumatism emphasis is here placed upon the importance of free use of the fruit juices. The influence of these has been thoroughly discussed above and there is no condition in which their influence is more important than in acute articular rheumatism.

Diphtheria requires a special discussion, though the choice of foods for diphtheria cases should be the same as that described above for general fevers. The condition of the throat in the diphtheria case introduces serious difficulties in the administration of food; soreness of the throat may seriously interfere with the swallowing even of liquid food and may even make recourse to nutrient enemata necessarv for a short time. If intubation becomes neces-sary still further difficulty with the swallowing arises. The patient may not be able to swallow liquids at all. As a rule, the semisolids and solids will be digested if they can be swallowed. Swallowing may be facilitated by lowering the head.

In severe cases of diphtheria there may be a paralysis as one of the later symptoms. If this paralysis involves the muscles of deglutition it will be necessary to introduce food into the stomach by means of a stomach-tube. The paralysis of the muscles of the larynx and base of the tongue will make the introduction of the stomach-tube especially easy.
