LIDO, Alessandro Vito et al. Occupational exposure and occurrence of pneumoconioses in Campinas, Brazil, 1978-2003. J. bras. pneumol. [online]. 2008, vol.34, n.6, pp.367-372. ISSN 1806-3713.  http://dx.doi.org/10.1590/S1806-37132008000600006.

OBJECTIVE: To develop and consolidate a comprehensive database on the occurrence of pneumoconioses in an industrialized region of Brazil, with a special focus on the activities most frequently related to these diseases. METHODS: A retrospective, observational study was conducted in order to gather data on cases of pneumoconioses treated at the outpatient clinic of the State University at Campinas Hospital das Clínicas between 1978 and 2003. Individuals diagnosed with pneumoconiosis, based on their occupational history and on chest X-ray findings of abnormalities consistent with interstitial lung disease involving the parenchyma, in accordance with the 1980 and 2000 recommendations of the International Labour Organization, were included in the study. RESULTS: A total of 1147 cases of pneumoconiosis were identified (1075 in males and 72 in females): 1061 cases of silicosis (92.5%); 51 cases of mixed-dust pneumoconiosis (4.45%); 15 cases of asbestosis (1.31%); 13 cases of phosphate rock-related pneumoconiosis (1.13%); and 7 cases of other types of pneumoconiosis (0.6%), including those related to exposure to coal, graphite and hard metals. The most common chest X-ray findings were 1/0, 1/1 or 1/2 profusion and small regular opacities (p, q or r), although 192 patients (16.74%) presented large opacities. There has been a substantial decline in the occurrence of the disease since the 1990s, and the duration of exposure was typically shorter than that observed in a study conducted in the United States. CONCLUSIONS: Our findings have been compiled into a comprehensive database for the investigation of pneumoconiosis in an industrialized area of Brazil. These data make it possible to conduct follow-up studies and develop health policies related to occupational respiratory disorders.
