The authors analyzed the documentation of 70 patients reported in 1996-1999 as suffering from occupational pneumoconiosis. In the majority simple silicosis (31 patients) was involved or simple miner´s pneumoconiosis (23 patients). As compared with previous work, the authors recorded shortening of exposure period in workers of black coal mines and quarries and shortening of the exposure time in simple silicosis and simple miner´s pneumoconiosis. In 38 patients also non- occupational diseases were found, most frequently cardiovascular, disease of the locomotor and digestive system. The problem of pneumoconioses (in particu- lar follow up examinations) deserves attention also in future.
