Abstract：
UNASSIGNED: Performance of routine Chest X-rays (CXRs) in asymptomatic individuals to assess hyperbaric exposure risk is controversial. The radiation risk may overshadow the low yield in many settings. However, the yield may be higher in certain settings, such as tuberculosis-endemic countries. We evaluated the utility of routine CXR in diving and submarine medical examinations in South Africa.
UNASSIGNED: Records of 2,777 CXRs during 3,568 fitness examinations of 894 divers and submariners spanning 31 years were reviewed to determine the incidence of CXR abnormality. Associated factors were evaluated using odds ratios and a binomial logistic regression model, with a Kaplan-Meier plot to describe the duration of service until first abnormal CXR.
UNASSIGNED: An abnormal CXR was reported in 1.1% per person year of service, yielding a cumulative incidence of 6.5% (58/894) of the study participants. Only four individuals had a clinical indication for the CXR in their medical history. A range of potential pathologies were seen, of which 15.5% were declared disqualifying and the rest (84.5%) were treated, or further investigation showed that the person could be declared fit.
UNASSIGNED: In South Africa, a routine CXR has a role to play in detecting abnormalities that are incompatible with pressure exposures. The highest number of abnormalities were found during the initial examinations and in individuals with long service records. Only four individuals had a clinical indication for their CXR during the 31-year span of our study. Similar studies should be performed to make recommendations in other countries and settings.

摘要：
■在无症状个体中进行常规胸部X光检查（CXR）以评估高压暴露风险是有争议的。在许多情况下，辐射风险可能会掩盖低产量。然而,在某些情况下，产量可能会更高，如结核病流行国家。我们评估了常规CXR在南非潜水和潜艇体检中的实用性。
■对31年的894名潜水员和潜艇运动员的3,568项体能检查中的2,777名CXR记录进行了审查，以确定CXR异常的发生率。使用比值比和二项逻辑回归模型评估相关因素，用Kaplan-Meier图来描述服务的持续时间，直到第一个异常CXR。
■在每人每年的服务中报告了异常的CXR，研究参与者的累积发生率为6.5%(58/894).在他们的病史中只有4个人具有CXR的临床指征。看到了一系列潜在的病理，其中15.5%被宣布不合格，其余(84.5%)接受治疗，或进一步调查显示该人可以被宣布健康。
■在南非，常规CXR在检测与压力暴露不相容的异常方面可以发挥作用。在初次检查期间和有长期服务记录的个人中发现的异常数量最多。在我们研究的31年中，只有4个人具有CXR的临床指征。应进行类似的研究，以便在其他国家和环境中提出建议。
