背景:希腊南部的一家大学医院。目的:对无症状的希腊人及外来移民进行常规胸部X 线检查,以确定结核病的患病率及其它有临床意义的疾病。设计:前瞻性研究。方法:共对4338名无症状者(56.8%为希腊人,43.2%为移民,年龄范围为 18-74 岁)进行胸部 X 线摄片,由两位有经验的胸部 X 线专家独立阅读,记录异常发现。经讨论建立最后的放射线学诊断。对所获结果进行统计学分析。结果:绝大多数(94.7%)胸部 X 线片的报告正常,发现 4 例(0.08%)有临床意义。无一例有活动性结核病描述。移民的陈旧性肺结核发生率高于希腊出生者,但无统计学意义。结论:希腊出生组的低结核病患病率提示无需进行放射学筛选,该项检查可免去。本研究未发现外来移民中结核病率高于希腊本地居民,此发现需经更大范围的前瞻性研究加以证实。
Background: A university hospital in southern Greece. Objectives: To conduct routine chest X-rays of asymptomatic Greeks and immigrants to determine the prevalence of tuberculosis and other clinically significant illnesses. Design: Prospective study. METHODS: A total of 4338 asymptomatic subjects (56.8% of Greeks and 43.2% of immigrants aged 18-74 years) underwent chest radiography and were independently read by two experienced chest X-ray specialists Abnormal discovery. After discussion, establish the final radiological diagnosis. The results obtained for statistical analysis. Results: The vast majority (94.7%) of the chest radiographs were normal and found that 4 (0.08%) had clinical significance. No case of active tuberculosis description. The incidence of old tuberculosis among immigrants was higher than that of Greeks, but it was not statistically significant. Conclusions: The prevalence of low-grade TB in the Greek-born group suggests that radiological screening is not required and this test may be dispensed with. This study did not find that the incidence of tuberculosis among immigrants was higher than that of Greek natives and the finding was confirmed by a wider range of prospective studies.
