老年人趾甲真菌病易感因素分析

目的 探讨老年人趾甲真菌病的易感因素. 方法 收集2005-2007年,我院60岁以上老年趾甲真菌病患者100例为病例组,同时收集60岁以上老年非真菌感染趾甲病患者100例为对照组,对两组患者的临床资料进行分析比较. 结果 病例组100例患者中,并存糖尿病24例,占甲真菌病并存疾病的首位,对照组并存糖尿病仅为6例,两组比较差异有统计学意义(χ2=12.706,P<0.05).病例组与对照组比较,下肢静脉曲张分别为31例和12例(χ2=10.695,P<0.05),足部畸形为36例和19例(χ2=7.248,P<0.05),趾甲外伤史为11例和3例(χ2=4.916,P<0.05),长期穿紧鞋史32例和12例(χ2=22.831,P<0.05),差异均有统计学意义.病例组47例女性患者中有12例既往有长期穿高跟鞋史. 结论 趾甲损伤、足部畸形、静脉曲张及糖尿病是趾甲真菌病的主要易感因素.

A clinical analysis of the predisposing factors for toenail onychomycosis in the elderly

Objective To evaluate the susceptibility to toenail fungal infection (FI) in the elderly. Methods Two hundred patients with toenail FI aged 60 years or older from 2005 to 2007 in our hospital were collected in our study, including one hundred elderly patients with toenail fungal infection (case group) and one hundred elderly patients without toenail fungal infection (control group). The clinical data of the patients in two groups were analysed. Results In case group, diabetes mellitus was the most common complication, accounting for 24% (24/100), while there were only 6 cases with diabetes mellitus (6%) in control group (P<0. 05). In case versus control group, there were 31 cases vs 12 cases with lower extremity varicose vein (P<0. 05), and 36 cases vs 19 cases with foot deformity, 11 cases vs 3 cases with toenail onychomychosis following trauma of their toes (P<0.05) ,32 cases vs 12 cases with history of wearing tight shoes (P<0. 05). In case group, 12 of 47 female patients used to wear high-heel shoes. Conclusions Toenail trauma, foot malformation, lower extremity varicose vein and diabetes mellitus are predisposing factors for toenail onychomycosis in the elderly.
