Risk of silicosis in cohorts of Chinese tin and tungsten miners, and pottery workers (I): an epidemiological study.
BACKGROUND Epidemiological evaluations of the risk of silicosis in relation to exposure to crystalline silica have raised the question of whether different types of silica dust exposures vary with respect to their ability to cause silicosis. The aim of this study is to compare the risk of silicosis among cohorts of silica dust-exposed Chinese tin miners, tungsten miners, and pottery workers and...
متن کاملCrystalline silica exposure, radiological silicosis, and lung cancer mortality in diatomaceous earth industry workers.
BACKGROUND The role of silicosis as either a necessary or incidental condition in silica associated lung cancer remains unresolved. To address this issue a cohort analysis of dose-response relations for crystalline silica and lung cancer mortality was conducted among diatomaceous earth workers classified according to the presence or absence of radiological silicosis. METHODS Radiological sili...
متن کاملRadiological progression and its predictive risk factors in silicosis.
OBJECTIVES To investigate the risk factors predicting radiological progression in silicosis in a prospective cohort study of patients with silicosis who were previously exposed to silica from granite dust. METHODS From among a total of 260 patients with silicosis contracted from granite work, 141 with available serial chest x ray films of acceptable quality taken over a period of 2 to 17 (mea...
متن کاملPhospholipid content of bronchoalveolar lavage fluid in granite workers with silicosis in Quebec.
BACKGROUND Some of the prominent features of silicosis are hyperplasia and hypertrophy of epithelial type II cells, which in experimental animals are often accompanied by accumulation of phospholipids in the lung. METHODS The total phospholipid content of lung lavage fluid and its composition in 28 granite stone cutters with long term exposure to silica dust (23 with radiological silicosis) w...

Since 1929, when compensation for silicosis first became payable to men in the coal mining industry, the number of disablement cases has increased rapidly, and there has been greater mortality from respiratory disease among coal miners in South Wales than elsewhere in Great Britain. In 1936 the Medical Research Council were asked by the Home Office and the Mines department to investigate the pr...
