目的：描述一起职业性矽肺暴发的流行病学、临床特征及相关的工作条件。方法：病例定义为2009年7月至2012年5月在加迪斯省从事石材切割、成型和精加工行业的男性，经波多黎各大学医院(CADIZ)肺科鉴定和诊断。对使用石英集团的工作场所进行了普查，以确定潜在接触工人的总数。结果：46名男性被诊断为矽肺，中位年龄33岁，从事台面制造工作的中位年龄为11年。在这些病例中，91.3%的病例通过高分辨率计算机断层扫描(HRCT)异常诊断为单纯性慢性矽肺。一名患者在研究期间死亡。雇主不遵守预防和控制措施的情况经常被报告，环境和个人保护措施的失败也是如此。结论：在房地产繁荣推动的高需求背景下，由于密集的职业暴露，新建筑材料如石英集团的使用增加了矽肺的发病率。如果不采取适当的预防措施，这种广泛的接触会带来风险。
Objectives: To describe the epidemiological and clinical characteristics of an outbreak of occupational silicosis and the associated working conditions.Methods: Cases were defined as men working in the stone cutting, shaping, and finishing industry in the province of Cadiz, diagnosed with silicosis between July 2009 and May 2012, and were identified and diagnosed by the department of pulmonology of the University Hospital of Puerto Real (Cadiz). A census of workplaces using quartz conglomerates was carried out to determine total numbers of potentially exposed workers. A patient telephone survey on occupational exposures and a review of medical records for all participants were conducted.Results: Silicosis was diagnosed in 46 men with a median age of 33 years and a median of 11 years working in the manufacturing of countertops. Of these cases, 91.3% were diagnosed with simple chronic silicosis, with an abnormal high-resolution computerized tomography (HRCT) scan. One patient died during the study period. Employer non-compliance in prevention and control measures was frequently reported, as were environmental and individual protection failures.Conclusions: The use of new construction materials such as quartz conglomerates has increased silicosis incidence due to intensive occupational exposures, in the context of high demand fuelled by the housing boom. This widespread exposure poses a risk if appropriate preventive measures are not undertaken.
