Abstract

Background: Tinea capitis is a contagious fungal infection that occurs predominantly in childhood. Although its incidence has declined, its epidemiological and mycological characteristics are continue to evolve. Objective: To assess changes in the epidemiological and mycological characteristics of tinea capitis in teenage patients in Southeastern Korea. Methods: We retrospectively investigated epidemiological and mycological characteristics of 202 teenage patientswith tinea capitis who visited Kyungpook National University Hospital and the Catholic Skin Disease Clinic from 1989-2018. Results: Of 202 patients, 177 patients showed KOH-positivity. Dermatophytes were cultured from 157 patients. The annual incidence of tinea capitis ranged from 0 to 30 between 1989 and 2018. Of 202 patients, 153 patients (75.74%) were male and 49 patients (24.26%) were female. The ratio of male to female was 1:0.32. For seasonal distribution, 78 patients (38.61%) visited our hospital in winter, 59 patients (29.21%) visited in spring, 35 patients (17.33%) visited in fall, and 30 patients (14.85%) visited in summer. Microsporum canis was the most common dermatophyte (44.06%) isolated from tinea capitis. Trichophyton tonsurans was the second most common dermatophyte (26.73%). For inhabitancy distribution, 151 patients (74.75%) lived in urban areas and 51 (25.25%) lived in rural areas. Conclusion: The epidemiological characteristics of teenage patients with tinea capitis were distinct from those of adults in annual incidence, sexual distribution and isolated dermatophytes. Trichophyton tonsurans was the main causative organism of tinea capitis in recent 10 years. These results are useful for the targeted treatment and prevention of tinea capitis.

韩国东南部青少年头癣的流行病学和真菌学特征:近10年来以癣毛癣菌为主要病原菌

背景:头癣是一种主要发生在儿童期的传染性真菌感染。虽然发病率有所下降，但其流行病学和真菌学特征仍在继续演变。目的:了解韩国东南部青少年头癣患者的流行病学和真菌学特征的变化。方法:回顾性分析1989-2018年在庆北大学医院和天主教皮肤病诊所就诊的202例青少年头癣患者的流行病学和真菌学特征。结果:202例患者中koh阳性177例。从157例患者中培养皮肤真菌。1989年至2018年间，头癣的年发病率在0 - 30之间。202例患者中，男性153例(75.74%)，女性49例(24.26%)。男女比例为1:0.32。季节分布方面，冬季就诊78例(38.61%)，春季就诊59例(29.21%)，秋季就诊35例(17.33%)，夏季就诊30例(14.85%)。犬小孢子菌是头癣中最常见的皮菌(44.06%)。第二常见的是毛癣菌(26.73%)。从居住分布来看，151例(74.75%)患者生活在城市地区，51例(25.25%)患者生活在农村地区。结论:青少年头癣患者的流行病学特征在年发病率、性别分布和分离性皮癣菌等方面与成人不同。毛发毛癣菌是近10年来头癣的主要病原菌。这些结果对针对性的治疗和预防头癣是有用的。

期刊介绍： The Journal of mycology and infection (Acronym: JMI, Abbreviation: J Mycol Infect) aims to publish articles of exceptional interests in the field of medical mycology. The journal originally was launched in 1996 as the Korean Journal of Medical Mycology and has reformed into the current state beginning on March of 2018. The contents of the journal should elucidate important microbiological fundamentals and provide qualitative insights to respective clinical aspects. JMI underlines the submission of novel findings and studies in clinical mycology that are enriched by analyses achieved through investigative methods. The journal should be of general interests to the scientific communities at large and should provide medical societies with advanced breadth and depth of mycological expertise. In addition, the journal supplements infectious diseases in adjunct to the field of mycology to address a well-rounded understanding of infectious disorders. The Journal of mycology and infection, which is issued quarterly, in March, June, September and December each year, published in English. The scope of the Journal of mycology and infection includes invited reviews, original articles, case reports, letter to the editor, and images in mycology. The journal is compliant to peer-review/open access and all articles undergo rigorous reviewing processes by our internationally acknowledged team of editorial boards. The articles directed to publication should encompass in-depth materials that employ scholastic values of mycology and various infectious diseases. Articles responding to critical methodology and outcomes which have potential to enhance better understanding of mycology and infectious diseases are also suitable for publication.
