The importance of securing a proper history cannot be overempha¬ sized. The history has a direct and significant bearing on the interpre¬ tation of the protein skin tests and other clinical findings. It often dictates the form of therapy to be instituted. The following history form, while far from being perfect, has served to cover in a practical manner almost every possible question pertinent to this subject. The average time required to take such a history in experienced hands was one-half hour. HISTORY (When recording any data, state the age of the patient with the month and year of the event.)A. Past History : 1. Infancy.-Breast fed? First bottle, and how prepared? When were other foods given and what were the disturbances, if any? Is there a history of "recur¬ rent bronchitis," "rhinitis" or vomiting? If so, can these conditions be associated with foods and other proteins? Were there eczema or other skin diseases? If so, age of onset, period of duration and parts affected? 2. Onset of Asthma.-Age? Month or season of the year? Gradual or sudden? Was there a history of wheezing, repeated attacks of bronchitis, catarrhal symptoms of the nose and conjunctiva prior to the onset of bronchospasms?If so, describe in detail. What association, if any, was there between the age of onset of the bronchospasms, attacks of wheezing or "recurrent bronchitis" to other diseases, such as pneumonia, pertussis, scarlet fever ; to operations, tonsil¬ lectomy and adenoidectomy, and to serum injections, diphtheria or other anti¬ toxins ? Describe in detail. If eczema, urticaria or angioneurotic edema occurred prior to or after the onset of asthma, state the interval of time between these conditions and its relation to the asthmatic state.3. Course of Asthma.-Trace the asthmatic state from its inception to the present time with reference to the frequency and duration of the attacks. Describe any special features that may have been associated with the attacks, such as fever, vomiting or "nose colds." Was there a definite history of freedom from asthmatic symptoms between attacks? If so, what are the longest and shortest intervals?What was the patient's mode of living, his condition of physical health? Was he free from intercurrent infections during these intervals of freedom from asthma? If wheezing was present between attacks, describe in detail. 4. Environmental Contact and Exposure.-What is the clinical effect of foods, dust, domestic animals, hair or feather pillows, mattresses, fur coats, fur trim¬ mings (collars or cuffs), blankets, furniture stuffing or toys?
