沿海地区手部慢性特殊感染病因学及诊治研究

目的 探讨沿海地区手部慢性特殊感染的致病因素,以及与结核杆菌的关系,为临床早期正确诊治提供依据。方法对2002年6月至2004年4月收治的29例手部慢性特殊感染病例做组织病理学检查,直接抗酸染色,普通细菌培养,真菌培养,分枝杆菌培养,并对分离菌株进行生化分型。结果29例患者中细菌培养阳性12例。其中普通细菌培养阳性2例,其中1例为星形诺卡氏菌,另1例为表皮葡萄球菌;分枝杆菌培养阳性10例。直接抗酸染色检查2例阳性。结论手部慢性特殊感染患者应同时做常规细菌培养,真菌及分枝杆菌培养。非结核分枝杆菌感染尤其是海分枝杆菌远比结核菌常见,是沿海地区手部特殊感染的主要致病因素。

The etiological study, diagnose and therapy of hand special chronic infections in littoral area

Objective To explore the etiological factors of hand special chronic infections and their relationship with tuberculosis, and to give evidence for clinical diagnosis as well as treatments. Methods From 2002 to 2004 pathologic inspection, acid-fast stain, bacterial cultication, mycobacterial cultivation were performed in all 29 cases of hand special chronic infections. Results All cases showed granulomatous lesions in pathological appearance, 2 positive in acid-fast stain, 12 positive in bacteria cultivation, and 1 nocardiosis, 1 staphylococcus epidermidis, 7 M.marinum, 1 M.tuberculosis, 1 M.fortuitum, 1 M.kansasii. Conclusions Non-tuberculo-mycobacterium(NTM) especially M.mariunm are far more important as the major factor than tuberculosis and other bacterial in hand special chronic infections. Bacteria cultivation should be routine examined for all cases.
