[Industrial bronchitis in workers exposed to hydroalcohol].

Objective: To identify the association between industrial bronchitis and exposure to hydroalcohol.

Methods: In a prospective study, 80 workers exposed to hydroalcohol answered a standardized questionnaire and had two spirometry tests based on the American Thorax Society (ATS) criteria, to evaluate functional capacity and predominant spirometric patterns. The test included the parameters: forced vital capacity (FVC), forced expiratory volume in one second (FEV1), the ratio FEV1/FVC, the peak expiratory flow (PEF), the forced expiratory flow 25-50 (FEF50) and the forced expiratory flow 25-75% (FEF 25%-75%).
