A retrospective epidemiologic study of 110 patients with chronic paronychia (CP) showed a female-male ratio of 2.3:1, whereas the ratio of patients attending the same clinic was 1.1:1 (p less than 0.001). The peak age range of patients with CP (40-49 years) generally was greater than that of the general dermatologic patients (20-29 years). Seventy-seven percent of the patients with CP were "manual workers," of which 48% were homemakers. Chronic paronychia was more common on the right fingers than the left fingers. The most commonly affected fingers were the right thumb (62%), followed by the right middle finger (52%), left thumb (57.6%), and left middle finger (51.5%). Mechanical trauma appears to be an important predisposing factor in CP. Sixty-two percent of 68 patients who had nail fold smears had positive findings for budding yeast cells, suggestive of candidal infection. All of the six patients for whom nail fold bacterial cultures were performed had positive results for enteric flora.
一项对110例慢性甲沟炎（CP）患者的回顾性流行病学研究显示，女性与男性的比例为2.3:1，而在同一诊所就诊的患者比例为1.1:1（p小于0.001）。CP患者的年龄峰值范围（40 - 49岁）总体上大于普通皮肤科患者（20 - 29岁）。77%的CP患者为“体力劳动者”，其中48%是家庭主妇。慢性甲沟炎在右手手指比左手手指更常见。最常受累的手指是右手拇指（62%），其次是右手中指（52%）、左手拇指（57.6%）和左手中指（51.5%）。机械性创伤似乎是CP的一个重要诱发因素。68例进行甲皱涂片检查的患者中，62%的患者芽生酵母细胞检查结果呈阳性，提示念珠菌感染。进行甲皱细菌培养的6例患者全部肠道菌群检查结果呈阳性。
