High prevalence of silicosis among stone carvers in Brazil

Abstract

Exposure to high levels of silica dust was associated with an increased prevalence of silicosis among stone carvers. Am. J. Ind. Med. 45:194-201, 2004.

An old threat in a new setting: High prevalence of silicosis among jewelry workers

“…DLCO results are divergent in other reports. In one report it was normal in workers who were heavily exposed to silica [Antao et al, 2004]; in another it was significantly reduced in 76 patients with silicosis [Ooi et al, 2003]. In our population, DLCO did not correlate with duration of exposure or chalk use.…”

“…In a similar study, stone carvers who had worked more than 15 years shown a higher prevalence of silicosis [Antao et al, 2004].…”

Silicosis in Manufacture of Electric Cable: Report of Four Cases

“…These two cases were the ones with the longest exposure times. Antao et al reported a relationship between the intensity of the opacities seen in HRCT and functional impairment 10) . According to radiological findings and pulmonary function test parameters the most severe effect was seen in Case 1 who eventually died due to respiratory failure.…”

Silicose

“…(12) A identificação de micronódulos, a presença de coalescên-cia de nódulos e a existência de enfisema, que habitualmente ocorrem nas regiões superiores e posteriores dos pulmões, são melhor visualizadas na tomografia computadorizada de tórax de alta resolução, quando comparada com a radiografia e a tomografia convencional. (12,(15)(16) Entretanto, seu emprego deve ser reservado como método de diagnóstico complementar nos casos duvidosos (Classificação OIT 0/1 ou 1/0) ou para auxiliar no diagnóstico diferencial com outras doenças, especialmente a sarcoidose e a linfangite carcinomatosa. (14,17) A biópsia pulmonar só está indicada na presença de alteração radiológica com ausência de dados na história ocupacional que sugiram a associação.…”
