Asbestos in the sputum, crackles in the lungs, and radiologic changes in women exposed to asbestos

In a rural community in South Africa historically exposed to asbestos environmentally and occupationally, 200 women who had worked with asbestos and applied for medical examination to determine compensable asbestos disease were evaluated. Clinical and radiologic evaluation, sputum collection, and microscopic analysis were done. A questionnaire elicited type of exposure, duration, decade of first work exposure, and environmental exposure. Crackles were present in the lungs of 166 women and asbestos fibers and ferruginous bodies were present in 122. Asbestosis was identified in 26 and plural plaques in 62. Auscultation for crackles (rales) is useful in the initial examination of former asbestos workers in rural communities of developing countries.
