The current global outbreak of artificial stone silicosis is a recrudescence of a major occupational disease in the context of a novel exposure source. Respirable crystalline silica exposure, even without frank pneumoconiosis, is associated with an increased risk of respiratory infection. Empyema is a well-recognized complication of bacterial pneumonia; pneumonia among working-age adults, in turn, has been epidemiologically linked to occupational exposure to fumes and dust, including silica. A connection between empyema and silica dust inhalation has not been reported, however, whether through antecedent pneumonia or another mechanism. We describe a case of silicosis initially presenting with empyema in a 31-year-old Computerized Numerical Control stone-cutting machine operator who had heavy exposure to artificial stone and other rock dust.
当前全球范围内人造石矽肺的爆发是一种新型暴露源下的主要职业病的再现。可吸入结晶矽尘暴露,即使没有明显的矽肺,也与呼吸道感染的风险增加有关。脓胸是细菌性肺炎的一种公认并发症;而青壮年人群的肺炎,反过来又与包括矽尘在内的烟雾和粉尘的职业暴露有关。然而,无论是通过先前的肺炎还是其他机制,矽肺和矽尘吸入之间的联系尚未被报道。我们描述了一例矽肺病例,最初表现为一名 31 岁数控石材切割机操作工的脓胸,该工人曾大量接触人造石和其他岩石粉尘。
