Abstract

Background

Pediatric alopecia is increasingly common, influenced by conditions like alopecia areata and infections such as tinea capitis, primarily caused by Microsporum canis. Diagnosing tinea capitis in primary care is challenging due to limited access to advanced tools, leading to treatment delays.

Objectives

This study evaluates the effectiveness of Wood's lamp for early diagnosis of tinea capitis and its role in distinguishing it from other pediatric alopecia types.

Methods

Fifty pediatric patients under 12 with alopecia were enrolled from March 2023 to March 2024. Data collected included contact history, CFW microscopy, fungal cultures, Wood's lamp examinations, treatments, and follow-ups.

Results

Wood's lamp identified 22 cases linked to animal contact, confirmed as Microsporum canis. Overall, 30 tinea capitis, 15 alopecia areata, and 5 trichotillomania cases were diagnosed. Post-treatment, fluorescence decreased in tinea capitis patients, who also showed hair regrowth, with no recurrence during follow-up.

Conclusions

Wood's lamp is a valuable, cost-effective diagnostic tool for tinea capitis, especially when combined with animal contact history, supporting its use in primary healthcare.

儿童犬小孢子虫头癣早期检测的伍德灯。

背景：儿童脱发越来越普遍，受斑秃和感染（主要由犬小孢子虫引起的头癣）等疾病的影响。由于获得先进工具的机会有限，在初级保健中诊断头癣具有挑战性，导致治疗延误。目的：本研究评价伍德灯在头癣早期诊断中的作用及其与其他儿科脱发类型的区别。方法：2023年3月至2024年3月，入选50例12岁以下儿童脱发患者。收集的数据包括接触史、CFW显微镜、真菌培养、伍德氏灯检查、治疗和随访。结果：伍德灯鉴定出22例与动物接触有关的病例，确认为犬小孢子虫。总共诊断出30例头癣，15例斑秃，5例拔毛症。治疗后，头癣患者的荧光下降，并出现毛发再生，随访期间无复发。结论：伍德灯是一种有价值的、具有成本效益的头癣诊断工具，特别是与动物接触史结合使用时，支持在初级卫生保健中使用。
