Nutritious food is of equal value with the open-air life. A liberal diet of milk and cream, eggs, meat and vegetables is indicated. Raw eggs swallowed whole with a little sherry, or pepper and salt on them, may be taken between meals, beginning with one and increasing the number till three are taken at a time, or nine daily. If the appetite is very poor it is best that a glass of milk be taken every two hours, varied by white of egg and water and meat juice. Drug treatment depends on individual symptoms, and can, therefore, only be given under a physician's care. Sanitarium treatment is the most successful, because patients are under the absolute control of experts and usually in an ideal climate. Change of climate is often useful, but patients should not leave their homes without the advice of a competent physician, as there are many questions to consider in taking such a step.[5] There is a growing tendency among physicians to give consumptives out-of-door treatment at their homes, if living out of cities, as careful personal supervision gives much better results than a random life in a popular climatic resort. =Prevention.=--Weakly children and those born of consumptives must receive a generous diet of milk, eggs, meat, and vegetables, and spend most of their time in the open air. Their milk should be heated for fifteen minutes to a temperature of 160 deg. F., in order to kill any germs of tuberculosis, unless the cows have been tested for this disease. The patient must have a separate sleeping room, and refrain from kissing or caressing other members of the family. The care of the sputum (expectoration) is, however, the essential means of preventing contagion. Out of doors, it should be deposited in a bottle which is cleaned by rinsing in boiling water. Indoors, paper bags or paper boxes made for the purpose are used to receive the sputum, and burned before they become dry. The use of rags, handkerchiefs, and paper napkins is dirty, and apt to cause soiling of the hands and clothes and lead to contagion. Plenty of sunlight in the sick room will cause destruction of the germs of consumption, besides proving beneficial to the patient. No dusting is to be done in the invalid's room; only moist cleansing. All dishes used by a consumptive must be boiled before they are again employed. =ASTHMA.=--This is a disorder caused by sudden narrowing of the smaller air tubes in the lungs. This narrowing is produced by swelling of the mucous membrane lining them, or is due to contraction of the tubes through reflex nervous influences. It may accompany bronchitis, or may be uncomplicated. It may be a manifestation of gout.
