Abstract:
UNASSIGNED: Tinea capitis (TC) is a common fungal infection of the scalp, especially in children. Trichoscopy is a noninvasive technique that allows rapid and magnified in vivo observation of the hair with the visualization of morphologic features that are often imperceptible to the naked eye.
UNASSIGNED: This study aimed to evaluate the usefulness of trichoscopy in clinical diagnosis and to study various clinico-morphological patterns of TC.
UNASSIGNED: This cross-sectional, observational study included 140 clinically diagnosed cases of TC seen during a period of 1 year (April 2021 to March 2022). All patients were evaluated using a dermoscope (DermLite DL4 Multispectral 3 Gen, San Juan Capistrano, CA, USA,10×).
UNASSIGNED: The prevalence rate of TC in this study was 2.69 per thousand population. The most common clinical variant was gray patch followed by kerion and black dot, and the most common etiological agent was Trichophyton tonsurans. The characteristic trichoscopic features were as follows: comma hairs (80%), followed by corkscrew hairs (68.6%), bent hairs (54.2%), zigzag hairs (35.7%), and morse code-like hairs (15%). Other findings included scaling (89.2%), followed by black dot (67.1%), broken hairs (42.8%), and crusting and pustules (32.1% each). Comma and corkscrew-shaped hairs were most common in the black dot type, whereas zigzag, bent hairs, and morse code hairs were common in the gray patch type of TC. There was a significant association between trichoscopic findings and type of TC.
UNASSIGNED: Trichoscopy can be considered a novel tool for rapid diagnosis and selection of the appropriate therapy and in the monitoring of treatment efficacy in TC.
摘要:
头癣(TC)是一种常见的头皮真菌感染,尤其是儿童。毛管镜检查是一种非侵入性技术,可以在体内快速和放大地观察头发,并可视化肉眼通常无法察觉的形态特征。
本研究旨在评估内窥镜在临床诊断中的有用性,并研究TC的各种临床形态学模式。
这个横截面,观察性研究包括在1年期间(2021年4月至2022年3月)发现的140例TC临床诊断病例.所有患者均使用皮肤镜进行评估(DermliteDL4Multispectrical3Gen,圣胡安·卡皮斯特拉诺,CA,美国,10×)。
本研究中TC的患病率为每千人2.69。最常见的临床变异是灰色斑块,其次是kerion和黑点,最常见的病因是扁桃体毛癣菌。特征性的毛发特征如下:逗号毛(80%),其次是开瓶器毛(68.6%),弯曲的头发(54.2%),之字形毛发(35.7%),和类似摩尔斯电码的毛发(15%)。其他发现包括缩放(89.2%),其次是黑点(67.1%),断发(42.8%),结痂和脓疱(各32.1%)。逗号和开瓶器形状的头发在黑点类型中最常见,而锯齿形,弯曲的头发,莫尔斯电码毛在TC的灰色斑块类型中很常见。三镜检查结果与TC类型之间存在显着关联。
毛管镜检查可以被认为是一种新颖的工具,用于快速诊断和选择适当的治疗方法以及监测TC的治疗效果。
