An analysis of 500 consecutive pulmonary tuberculosis cases shows that lower lungfield tuberculosis occurs in 6.8 percent of the negroid population studied and therefore shows no racial predelection. The ratio of female to male involvement was 3:1. A clear association with young women and with pregnancy with or without other infections was demonstrated. Affected men were in the much older age group. Some association with diabetes and heart failure were also observed. The initial diagnosis of most of these patients was basal pneumonia or lung abscess. Therefore, the most useful clinical pointers were productive cough with or without haemoptysis unresponsive to various conventional antibiotics. The right base was most favoured and cavitation with fluid levels were frequent. We believe that the aetiological factors would include stress as could occur with pregnancies and poor basal tissue oxygenation due to diminished basal expansion in abdominal distension or cardiac failure.
对500例连续性肺结核病例的分析显示，在所研究的黑人人群中，下肺野结核的发生率为6.8%，因此不存在种族易感性。女性与男性受累比例为3:1。已证实与年轻女性以及妊娠（无论有无其他感染）有明确关联。患病男性年龄较大。还观察到与糖尿病和心力衰竭有一定关联。这些患者多数最初被诊断为基底肺炎或肺脓肿。因此，最有用的临床指征是使用各种常规抗生素治疗无效的、伴有或不伴有咯血的咳痰。右肺底部最常受累，且常有伴有液平的空洞形成。我们认为病因包括妊娠可能导致的应激以及腹胀或心力衰竭时基底扩张减弱所致的基底组织氧合不足。
