| Resumen |
The relationship between silica dust exposure in gold mines and the type of emphysema was studied in a group of 1,553 white gold miners who had undergone autopsy examination between 1974 and 1987. Of particular interest was the contrast between centriacinar and panacinar emphysema as they relate to silica exposure and the presence of silicosis. Subjects with significant emphysema, that is, with an emphysema score of 30% or more, were classified as having predominantly panacinar or predominantly centriacinar emphysema, and compared to those without emphysema (emphysema score ≤10%). In conclusion, centriacinar emphysema was found to be more common than panacinar emphysema in smoking miners, but in nonsmokers insignificant panacinar emphysema was more common. Both types of emphysema were positively related to silica dust exposure, and centriacinar emphysema was related to the presence of silicosis of the lung. |
