Despite the changes in their epidemiology, and the improving level of hygiene of the population, tinea capitis is still considered a public health problem in our country, and is the most common type of dermatophytosis in our country. The aim of our study was to evaluate the epidemiological, clinical and mycological features of tinea capitis in children encountered in the Tunis region. A retrospective study concerned 1600 children aged 6 months to 15 years suspected to have tinea capitis was conducted in Parasitology-Mycology laboratory, Rabta hospital, over a 10-years period (2005-2014). Dermatophyte infections were confirmed using scalp scrapings examinated with direct microscopy using potash at 30% and/or culture on Sabouraud medium agar. Tinea capitis diagnosis was confirmed in 947 cases (59.18%). The sex ratio was 2.61 and the average age of 6.28 years with predominance in the age group of 4 to 8 years (52.27%). The most common clinical presentation was ringworm (87.65%). Ringworm large plaque was predominant (65.9%). Direct examination was positive in 884 cases (93.35%). Microsporic tinea was the most frequent (63.25%) followed by trichophytic tinea (29.78%). Positive cultures of dermatophytes were obtained in 912 cases (96.30%). The following dermatophyte species were isolated: Microsporum canis (67%), Trichophyton violaceum (31.68%), Trichophyton mentagrophytes (0.66%), Microsporum audouinii (0.22%), Trichophyton schoenleinii (0.22%) and Microsporum gypseum (0.22%). M. canis is currently the most frequently incriminated species in tinea capitis in Tunisia. This change is related to a change in behavior of our population, in fact the cat; main reservoir of M. canis cohabiting increasingly with Tunisian families.
尽管头癣的流行病学情况有所变化，且人群卫生水平不断提高，但在我国头癣仍被视为一个公共卫生问题，并且是我国最常见的皮肤癣菌病类型。我们研究的目的是评估突尼斯地区儿童头癣的流行病学、临床和真菌学特征。在拉卜塔医院寄生虫学 - 真菌学实验室进行了一项回顾性研究，该研究涉及1600名年龄在6个月至15岁疑似患有头癣的儿童，研究时间段为10年（2005 - 2014年）。使用30%的氢氧化钾进行直接显微镜检查头皮鳞屑和/或在沙氏培养基琼脂上培养来确诊皮肤癣菌感染。947例（59.18%）确诊为头癣。男女比例为2.61，平均年龄为6.28岁，以4至8岁年龄组为主（52.27%）。最常见的临床表现是癣（87.65%）。大斑块癣最为常见（65.9%）。884例（93.35%）直接检查呈阳性。小孢子菌性头癣最为常见（63.25%），其次是毛癣菌性头癣（29.78%）。912例（96.30%）皮肤癣菌培养呈阳性。分离出以下皮肤癣菌种类：犬小孢子菌（67%）、紫色毛癣菌（31.68%）、须癣毛癣菌（0.66%）、奥杜盎小孢子菌（0.22%）、许兰毛癣菌（0.22%）和石膏样小孢子菌（0.22%）。犬小孢子菌目前是突尼斯头癣中最常涉及的菌种。这种变化与我国人群行为的改变有关，实际上，犬小孢子菌的主要宿主猫越来越多地与突尼斯家庭共同生活。
