Sažetak
The author's task was to find out whether in the asbestos mines and factory (the latter working only since 1947) at Korlače in the Ibar basin there were cases of pneumoconiosis so that the necessary technical protection could be introduced. Geomorphological, mineralogical, petrographical and chemical data pointed to the likelihood of that group of workers suffering from anthraco-silicosis in addition to abestosis. The author describes the production process and the method of work, he also discusses information on ecological and other factors on the various categories of workers. However, the bulk of the workers arc either peasants-miners or professional miners. A socio-economic enquiry organized among the workers brought forward the following problems awaiting solution: hygiene of housing, healthy vacationing, food and clothing, organization of hygiene in the factory. The enquiry touched also on the problem of the fluctuation of workers in the various mines. Tb at fluctuation may account for the large number of mixed pneumoconioses in that region. Only 80 workers (22.2%) were examined out of the total of 360. Radiographies on normal film were made of 76 workers (21.1%). The clinical and radiological part contains data obtained from examinations, radiographs and laboratory work. The objective findings include a high incidence of conjunctivitis (71.2%). goiter (31.7%), bronchitis (50%), diminishing of vital capacity (in 84.9% of cases), diminishing of the respiratory stretching of the thorax (in 84.9 per cent of cases) and changes in the orthodiagram of the heart. The author describes the radiographs, the classification of pneumoconiosis in the workers as well as its diagnosis. He discusses difficulties and errors relating to the interpretation of radiographs as well as the differences or opinions referring thereto. Out of the total of 76 radiographs 6 (7.8%) were found without changes, 17 (22.5%) were suspect, 22 (28.9%) had asbestosis. 29 (38.2%) anthraco-silico-asbestosis, and 2 (2.6%) anthraco-silicosis. Tuberculous lesions were diagnosed in 96.3% of cases of which 3.7% cases had active closed tuberculosis. The changes in the skin of the soles and palms could not be identified with certainty as asbesto warts. Hematuria was found in 58.5% eases. Its cause could not be identified hut its incidence is in direct ratio to exposure during work. The sputum of 39 out of 52 examined persons contained asbesto needles and single, atypical asbesto corpuscles with a positive Perls reaction were found in 5 cases.
