Abstract
One hundred thirty patients with Siberian silicosis occurring under exposure to large amounts of dust at labor in a siberian mine were analyzed for 67 clinical and 122 laboratory data. Eighty-eight of 130 patients are now alive, but 42 have already died. When they started work, 122 of the patients were under thirty years of age. The duration of work was 7 to 12 months for 17 patients, 13 to 18 for 43, and 19 to 24 for 40. Seventy-six of 99 patients were initially diagnosed with lung tuberculosis and 23 with silicosis. Almost all patients have complained of respiratory symptoms such as shortness of breath, cough, sputum, and cyanosis. All of the pulmonary function tests including %VC, FEV1.0/FVC, V25/height, RV, TLC, and DLco showed abnormal values. The chest roentogenograms showed 3 of type 1, 22 of type 2, 55 of type 3, and 124 of type 4. Of 124 type-4, large opacities, 84 were type A, 28 B, and 12 C. Of 416 small opacities, 144 were type P, 191 Q, and 81 R. The complications and secondary changes that appeared with progression of the disease were lung emphysema, hilar and mediastinal lymphnode enlargement, egg shell calcification in lymphnode, and bulla or bleb.
