Itchy maceration of the toe webs is common in warm and humid weather. Some cases do not respond to treatment for tinea or eczema.
Patients with foot intertrigo with a poor response to antifungal or antiinflammatory treatment from 2004 to 2009 were included in this study. Their general characteristics were recorded. Bacterial and fungal cultures as well as potassium hydroxide preparations were performed.
We recorded 32 episodes of foot bacterial intertrigo in 17 patients. The disease was more common in men (82%) and the mean age of the patients was 59 years. The main clinical finding was maceration of the toe webs. The majority of bacterial cultures grew mixed pathogens (93%). Pseudomonas aeruginosa, Enterococcus facealis and Staphylococcus aureus were the most common pathogens. Autoeczematization was present in 50% of the 32 disease episodes.
Foot bacterial intertrigo is not a rare condition and can easily be confused with interdigital tinea or eczematous dermatitis. Proper identification of bacterial organisms is critical for early effective antibiotic therapy. Patients should be instructed about proper foot hygiene, which is important to prevent recurrent infections.
趾间皮肤浸渍伴瘙痒在温暖潮湿的天气中很常见。有些病例对抗真菌或湿疹治疗无反应。
本研究纳入了2004年至2009年间对抗真菌或抗炎治疗反应不佳的足部擦烂患者。记录他们的一般特征。进行细菌和真菌培养以及氢氧化钾涂片检查。
我们记录了17例患者的32次足部细菌性擦烂发作。该病在男性中更为常见（82%），患者的平均年龄为59岁。主要临床发现是趾间皮肤浸渍。大多数细菌培养物生长出混合病原体（93%）。铜绿假单胞菌、粪肠球菌和金黄色葡萄球菌是最常见的病原体。32次发病中有50%出现自体湿疹化。
足部细菌性擦烂并非罕见病症，且容易与指间癣或湿疹性皮炎相混淆。正确识别细菌对于早期有效抗生素治疗至关重要。应指导患者保持足部卫生，这对于预防反复感染很重要。
