Observational study of all incident Tinea pedis cases, realised from 2001 to 2007 at the Dermatology Clinic of the University of Cagliari, Italy, which is the main reference centre for dermatologic diseases in central southern Sardinia.
All patients referred for foot inflammatory pathologies were included in the study. Samples of all clinically visible lesions were taken for mycological examination (20% KOH and culture). When lesions were absent samples were also taken from the IV inter-digital space of both feet to identify eventual sane carriers. Detailed anamneses investigated work, life habits, sports and predisposing conditions such as hyperhidrosis and previous pathologies of the feet.
The study enrolled 1568 patients, of which 918 (510 male-408 female) presented clinical manifestations whereas other 650 (426 male-224 female) were asymptomatic. Tinea pedis was diagnosed in 232 (14.79%), 163 male-69 female aged between 11 and 78 years, all in the group with clinical manifestations. The identified dermatophytes were Trichophyton mentagrophytes 115 cases (49.56%), Trichophyton rubrum 110 cases (47.42%) and Epidermophyton floccosum 7 cases (3.08%). Mycological exams in patients without clinical signs were always negative for dermatophytes, while rare colonies of Candida albicans were identified in 3 cases (0.46%).
Tinea pedis represents a common public health problem, which occurs mainly in male ageing from 16 to 45 years, when working and leisure activities are at their maximum. The absence of dermatophytes identification in 650 asymptomatic patients suggests that the sane carrier condition is a very rare event.
对 2001 年至 2007 年期间于意大利卡利亚里大学皮肤科诊所就诊的所有初发性足癣病例进行观察性研究，该诊所是撒丁岛中南部地区皮肤科疾病的主要参考中心。
本研究纳入所有因足部炎症性病变就诊的患者。对所有临床可见皮损进行真菌学检查（20%KOH 和培养）。当皮损缺失时，还从双脚第四趾间采集样本，以确定是否存在无症状带菌者。详细的病史调查了工作、生活习惯、运动和易患因素，如多汗症和足部先前的疾病。
本研究共纳入 1568 例患者，其中 918 例（510 例男性-408 例女性）出现了临床表现，而另外 650 例（426 例男性-224 例女性）无症状。232 例（14.79%）患者被诊断为足癣，其中 163 例（69 例男性-93 例女性）年龄在 11 至 78 岁之间，均为有临床表现的患者。鉴定出的皮肤癣菌包括毛癣菌 115 例（49.56%）、红色毛癣菌 110 例（47.42%）和絮状表皮癣菌 7 例（3.08%）。无临床症状患者的真菌学检查均未发现皮肤癣菌，但在 3 例（0.46%）患者中发现了罕见的白色念珠菌菌落。
足癣是一个常见的公共卫生问题，主要发生在 16 至 45 岁的男性中，此时工作和休闲活动最为频繁。650 例无症状患者中未鉴定出皮肤癣菌，提示无症状带菌者情况非常罕见。
