[Food allergy in asthma. Diagnostic significance of peripheral eosinophils].

Thirty one patients with suspicion of asthma due to food allergy (lack of correlation between allergic sensitivity and asthmatic attacks, association of clinical features suggestive of food allergy, no response to the pharmacological treatment) received an elimination diet. A second group (control group) of 51 asthmatic patients were enrolled in the study for a better evaluation of the diagnostic significance of blood eosinophil counts in food-induced asthma. 29-31 patients who took a variable oligoallergenic diet had a baseline blood eosinophilia greater than 600/mm3 (range 600-2100/mm3).

Genetic factors in nonspecific bronchial hyperreactivity. An epidemiologic study.

We tested bronchial reactivity to carbachol in 50 asthmatics, healthy parents of 40 asthmatic children, and 70 healthy subjects with no personal or family history of asthma. Stepped doses of carbachol (0.1%) aerosol were given until a 50% drop in forced expiratory flow rate from 25% to 75% was observed, or until the subject had inhaled 80 of his or her own vital-capacity equivalent volumes of the aerosol.

[Multicenter study on bronchopneumonia treated in a hospital environment in Friuli-Venezia Giulia: 2) Antibiotic therapy].

An analysis of a year's admissions for Pneumonia in all the Paediatric Department of the Region Friuli Venezia Giulia is presented. The study was conducted as activity of the Regional Section of the Italian Paediatric Society. The survey of the 14 Paediatric Centres produced a total of 536 cases of Pneumonia in the period January-December 1982 and was focused on antimicrobial therapy adopted pre and after hospitalization.
