Anthracosilicosis (AS), a prevalent form of pneumoconiosis among coal miners, results from the accumulation of carbon and silica in the lungs from inhaled coal dust. (unifesp.br)
Free silica2
The prevalence of pneumoconiosis was related to the number of years underground, particles per cubic meter, and free silica content of the dust. (cdc.gov)
There is now convincing evidence that several CTDs, including scleroderma (SSc), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE) are associated with exposure to crystalline free silica (CFS), and evidence regarding other CTDs is evolving. (dermatoljournal.com)
Silicosis4
The Hawk's Nest tragedy (1932-1934), in which more than 400 workers died of acute silicosis and tuberculosis after working on the tunnel at Gauley Bridge, West Virginia, reinforced the prevalent theory that silica content was the critical etiological agent in pneumoconiosis. (cdc.gov)
Because of the relatively high silica content and similarity to silicosis, the term "anthracosilicosis" was used to describe the pneumoconiosis found among those miners. (cdc.gov)
This article summarises recent literature on the topic of the resurgence of silicosis and silica-induced CTDs and reminds dermatologists of the importance of taking a thorough occupational history in all patients. (dermatoljournal.com)
At the same time, there has also been a resurgence of cases of silicosis in the coal mines of the USA, related primarily to higher silica exposures 14 , and the association between coal dust exposure and arthritis has been re-visited 15 . (dermatoljournal.com)
Pneumoconiosis1
One reason for the relatively late recognition of CWP as a distinct disease entity in the United States was the early emphasis placed on the etiological role of silica in pneumoconiosis. (cdc.gov)
