There is a dearth of Brazilian studies analyzing the effect of ongoing exposure to silica among former copper mine workers, as radiographic readings for silicosis have received widespread medical attention. The scope of this study is to investigate the clinical and radiological manifestations of silicosis among former copper mine workers. A sample of 100 former copper miners had their clinical and occupational histories recorded and underwent chest radiography in a cross-sectional study that included personal interviews in which their age, sex and time worked in copper extraction were recorded. Patients with recent chest X-Rays brought them with them, or they signed a term of consent and X-Rays were taken and analyzed by the radiologist using the Student t Test and Pearson test. Among the 100 miners, 35% had silicosis, 11% had conditions other than silicosis, such as tuberculosis, emphysema, chronic pulmonary obstructive disease, and 54% had no pulmonary lesions. The high incidence of silicosis reinforces the recommendation that exposure should be halted as soon as an X-ray detects the condition.
由于矽肺病的影像学诊断已受到广泛的医学关注，巴西针对曾从事铜矿开采工作的工人持续接触二氧化硅的影响进行分析的研究较少。本研究旨在调查曾从事铜矿开采工作的工人矽肺病的临床和放射学表现。在一项横断面研究中，对100名曾从事铜矿开采工作的工人进行了临床和职业史记录，并对其进行了胸部X光检查，该研究包括个人访谈，记录了他们的年龄、性别以及从事铜矿开采工作的时间。有近期胸部X光片的患者带来片子，或者他们签署同意书，由放射科医生拍摄X光片并使用学生t检验和皮尔逊检验进行分析。在这100名矿工中，35%患有矽肺病，11%患有除矽肺病以外的其他疾病，如肺结核、肺气肿、慢性阻塞性肺疾病，54%没有肺部病变。矽肺病的高发病率进一步强化了以下建议：一旦X光检查发现病情，应立即停止接触。
