Silicosis con corto tiempo de exposición

Abstract

A study made of 1,901 cases of silicosis, in various stages, coming from mines located at different altitudes. Of these, 763 were a micronodular form of silicosis, 295 were macronodular, 253 were confluent and 590 were silicotuberculosis. The average working period for each stage of this affection was 10 years

Of the 1,901 cases, 344 (18.1 per cent) of the patients were found to have worked for less than five years in all. Of these cases 344, or 53.5 per cent were micro and macronodular in form and 46.5 per cent were confluent, with or without infection

Studies were made of 146 and 95 cases of silicosis, in various stages, coming from nine mines in a region with a high silicosis potential. The average working period was eight years and the percentage of cases with less than five years of work was 37.7 and 6.6

This situation shows that the trend of absenteeism is different in the two regions. In 2,027 and 3,319 cases of silicosis found in the mining regions of Huancavelica, Junin and Pasco, 77.7 per cent and 0.4 per cent had a work period of more than 20 years. Thus there is not stability in mining work because of the high risk involved

The conclusion to be drawn from these percentages is that silicosis is a serious public health problem in Peru, particularly in some mining regions, not only because of high-risk environmental conditions but because of the prevalence of tuberculosis ... (AU)
