Abstract

These radiologic studies were carried out on 265 cases of silicosis which were diagnosed clinically atindustrial Accident Hospital affiliated with Catholic Medical Collage, suring the period of 3 years from 1974 to1976. 265 cases of silicosis consisted of 96 cases (35%) of coal miner, 91 cases (34%) of coal choicer and 82cases (31%) of others. The average age was 42.2 years and average working period was 9.2years. Qualitative andquantitative features in the analysis of roentgen findings were based on UICC/Cincinnati and KLO classification.The qualitative features showed 26% of "p" opacity, 46% of "q" opacity 4% of "r" opacity as rounded profusion and5% of "s" opacity, 11% of "t" opacity, 2% of "u" opacity as irregular profusion of small opacities.Large opacitiesshowed 3% of group A, 2% of group B and 1% of group C. Quantitative features revealed 25% of Type 1, 54% of Type2, 16% of Type 3 and 5% of Type 4. The qualitative and quantitative features showed significant differences as ageand working period increased with age and working period. Major complications were pulmonary emphysema,tuberculosis and pleural abnormalities.
