Apparent onset of coal-workers' pneumoconiosis after leaving the mines.
Campbell-Orr, H. (I954). Trans. Ophthal. Soc. U.K., 74, 367. Paris v. Stepney Borough Council (I95I). I. All E.R. 42. The answer to the second question is increasingly likely to be 'yes' towards each end of the scale. Loss of binocular visual acuity is a greater loss in a man with poor eyesight because visual acuity falls from a higher level using both eyes to a lower level using one, even thou...
متن کاملEffect of Dust Suppression Measures on the Prevalence of Coal-workers' Pneumoconiosis in the Dutch Coal-mines.
The underground workers in the Dutch coal-mines have been radiographed (70 mm.) seven times since 1949. The prevalence of coal-miners' pneumoconiosis shows a continuous decrease in all age groups. To evaluate the effect of the intensive system of dust suppression over this period a cohort analysis was made of the proportion ofmen with pneumoconiosis with the same number of years of exposure und...
متن کاملPneumoconiosis in Central Indian coal-mines.
Extensive surveys carried out in Europe and America have shown the incidence of coalworkers' pneumoconiosis to be widespread (Flinn, Seifert, Brinton, Jones, and Franks, 1941; Fletcher, 1955). In India, however, the prevalence of this disease has never been investigated, and a report published by the government of India in 1946 (Deshpande, 1946) stated that there was no conclusive evidence that...
متن کاملPrevalence and pathogenesis of pneumoconiosis in coal workers.
Dust dose and composition do not appear to account wholly for changes in the prevalence of coal workers' pneumoconiosis in Europe. In certain coal pits high progression evidently occurred with relatively low dust exposure or vice versa, whereas progression in relation to dust levels might be variable. Exceptionally high quartz concentrations occur in coal mine dust when pneumoconiosis may progr...
متن کاملSilicosis and coal workers' pneumoconiosis.
Exposure to coal mine dust and/or crystalline silica results in pneumoconiosis with initiation and progression of pulmonary fibrosis. This review presents characteristics of simple and complicated coal workers' pneumoconiosis (CWP) as well as pathologic indices of acute and chronic silicosis by summarizing results of in vitro, animal, and human investigations. These results support four basic m...
