The incidental diagnosis of two cases of silicosis at Messejana Hospital, Fortaleza, capital of Ceará state, triggered a field research conducted with the objective of investigating the incidence of silicosis in pit diggers in four towns in the Ibiapaba Mountain Range, at the state's northwestern area, northeastern Brazil. Out of a universe of 1,050 pit diggers in the area, 366 participated in the study; they were all males ranging in age between 16 and 76 years old (average 39 years). The excavation and the sickening process were described and a dust exposure index in pit diggers (DEIPD) was defined. The study sample indicated a rate of 121 (33.06%) silicotics and possibly silicotics. The radiologic findings were related to the DEIPD and indicated significant prevalence of disease. Furthermore, during the research period, from 1986 to 1989, 30 (34.9%) silicotics died of respiratory failure and wasting of body tissues. The data suggested that these men were afflicted with a severe occupational health problem, possibly scattered throughout a large area in northeastern Brazil, where manual pit excavations occur during the whole year and increase during drought periods.
在巴西东北部塞阿拉州首府福塔莱萨的梅西亚纳医院,两例矽肺病的偶然诊断引发了一项实地研究,其目的是调查巴西东北部伊比亚帕巴山脉四个城镇的矿工矽肺病发病率。在该地区1050名矿工中,366人参与了研究;他们均为男性,年龄在16至76岁之间(平均39岁)。描述了挖掘和患病过程,并定义了矿工粉尘暴露指数(DEIPD)。研究样本显示矽肺病患者和可能的矽肺病患者比例为121人(33.06%)。放射学检查结果与DEIPD相关,表明疾病的患病率很高。此外,在1986年至1989年的研究期间,30名(34.9%)矽肺病患者死于呼吸衰竭和身体组织消耗。数据表明,这些人患有严重的职业健康问题,可能在巴西东北部的大片地区都有,那里全年都有人工挖掘矿井的情况,干旱时期更为频繁。
