Fluoro-edenitic fibres in the sputum of subjects from Biancavilla (Sicily): a pilot study.
Environ Health
June 2006
Department of Traumatology, Orthopaedics and Occupational Medicine - University of Turin, Via Zuretti 29 - I-10126 Turin, Italy.
Background: An excess of mortality for malignant neoplasms of the pleura in Biancavilla, promoted an investigation for pleural mesothelioma, disclosing 17 cases. As the absence of known sources of asbestos exposure, a local stone quarry, located near the inhabited area, used for the extraction of building materials, was investigated. Amphibolic fibres were found in the quarry and identified as fluoro-edenite "new end-member of the edenite / fluoro-edenite series" and recognized as the fluoro-edenite holotype by International Mineralogical Association--Commission on New Minerals and Mineral Names.

Mites were observed in 55 pulmonary specimens examined routinely over a 4.5-yr period. The 55 specimens included 33 spontaneous and 12 aerosol-induced sputum samples, nine bronchial washings, and one fine-needle aspirate.

There were 42 central and 112 peripheral lesions: 6 adenocarcinomas and 28 squamous-cell carcinomas were centrally located and 69 adenocarcinomas and 27 squamous-cell carcinomas were peripherally located. Repetition of sputum sampling at least three times was preferred, especially in central lesions, which were detected in 57% to 64% of the cases by either three-day-pooled or aerosol-induced specimens.

During the first two years, slides were prepared by the "pick and smear" method; thereafter, the Saccomanno technique was used. Each specimen was examined for both the degree of cellular atypia and the number of ferruginous bodies.
