A QUARTER of the earth's crust is composed of silicon, so it is not surprising that the inhalation of dust has been recognised for centuries as a cause of shortness of breath in miners and stone operatives. In 1649 Dimerbrook (Collins, 1915) described chest rigidity associated with dyspncea in the granite workers of the Carpathians, who were themselves painfully aware of the occupational hazard...

OBJECTIVE Occupational lung disease due to silica dust is one of the most common work-related injuries. In denim sandblasting, workers are exposed to silica that may cause immediate mortality, especially in young people. The aim of this study was to assess the multidetector computed tomography (MDCT) findings of silicosis in denim sandblasters and to better define the role of MDCT in the early ...

In November 1988, a physician in west Texas reported three cases of silicosis in sandblasters to the Ector County Health Department (ECHD). One of the workers, a 34-year-old man, subsequently died with acute silicotic alveolar proteinosis. All three workers had been employed at a facility that sandblasted oil-field drilling pipes. Following the physician's report, in January 1989, the ECHD and ...

The most common cause of cavitation in progressive massive fibrosis (PMF) in patients with silicosis is infection with Mycobacterium tuberculosis. However, cavitation of PMF as a result of ischaemic necrosis has also ben identified as a rare entity in silicosis. A 40-year-old male, non-smoker, working as a stonecutter for 30 years presented with a five years history of exertional breathlessness...
