Asbestos-related radiographic abnormalities in elevator construction workers.
Elevator construction workers are exposed to asbestos dust during construction and refurbishment work on older buildings. We screened a cohort of workers, all with greater than 20 yr of employment in the industry, with clinical examinations, chest radiography ("B" reader interpretations), and routine spirometry. Twenty of the 91 workers (22%) had evidence of pleural disease, but none of them had an interstitial process consistent with asbestosis. Of those with pleural thickening, 15 had bilateral circumscribed plaques and five had unilateral plaque formation. There were no cases of diffuse pleural thickening, benign pleural effusions, or mesothelioma identified in our cohort. The difference in the mean body mass index of those with pleural abnormalities (29.18 +/- 3.95) and those without (27.7 +/- 3.86) was not statistically significant (p = 0.135). We conclude that elevator construction workers have an increased risk for the development of asbestos-related pleural disease.
