Proceedings of the VIIth International Pneumoconioses Conference, August 23-26, 1988, Pittsburgh, Pennsylvania, USA. Atlanta, GA: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. 90-108, 1990 Sep; (Part I):426-427
A study was made of 48 cases of asthma of occupational origin from industrial workers of Madras City over a period of 2 years. Of the 48 cases, 52% were aged 20 to 29 years, 27% were between 30 and 39 years of age. Lung function tests were performed because the chest X-ray results were not specific for asthma, and also to assess the severity of respiratory impairments. The obstructive type of ventilatory defects were due to narrowing of lung airways. Elimination of the causative agents from the workplace by methods such as exhaust ventilation and hoods or enclosures was the best method of treatment. Desensitization with cotton dust and flower mill dust is under trial. The author states that routine bronchodilators with tablets, injections or aerosols, steroids and chromolynsodium are also being tried.
