Silicosis, Coal-mine Pneumoconiosis in Connection with Tuberculosis in Slovakia in a Longitudinal Survey

The investigation was aimed at the evaluation of silicosis, coal-miner pneumoconiosis and silicotuberculosis (sitb) in the periodof 1977 -⁠ 96. The authors draw attention to the fact that the number of sitb cases notified at occupational diseases in Slovakia, i.e.202 cases over 20 years, decreased significantly (from 83 cases in the period 1977 -⁠ 1981 to 16 cases in 1992 -⁠ 1996).While in the first, five-year period of observation, sitb and pneumoconioses in coal-miners with active sitb constituted 21.1% ofnotified cases of pneumoconioses (silicoses and coal-miner pneumoconiosis), the incidence was 8.8% in the period of 1992 -⁠ 1996.In 175 workers in the Mid-Slovakia region (41.7 % from ore mines, 33.1% from coal mines, the rest from mixed exposure inmetal industries, tunnelling and stonecutting) the mean age at the subgroup of pneumoconiosis notification with an X-ray picture ofsmall opacities was 55.5 ± 9.9 years (mean ± S.D., n = 146). It became obvious that in he period of 1992 -⁠ 1996, smoking minerswere affected in notified silicosis significantly earlier than non-smokers (at the age of 53.1 ± 1.5 versus 57.9 ± 1.7 years, mean ±S.E., p
