目的 观察防风通圣散加减方联合微针导入米诺地尔治疗脾胃湿热型雄激素性脱发的临床疗效.方法 将60例脾胃湿热型雄激素性脱发患者随机分为对照组和治疗组,每组30例.对照组患者接受微针导入米诺地尔治疗,治疗组患者在对照组基础上口服防风通圣散加减方.观察并比较两组治疗前后脱发症状、脾胃湿热症状、皮肤镜下毛发相关指标、脂质代谢水平及不良反应发生情况.结果 在提高皮肤镜下每平方厘米毛发数、直立再生毛发数,降低皮肤镜下毳毛数、单一毛囊单位数和褐色毛周征数方面,以及在降低脱发、头皮瘙痒、头发油腻、头屑、新发不生症状积分方面,治疗组显著优于对照组(P<0.05);与治疗前比较,治疗组治疗后口干口苦、纳呆、便溏、身重乏力积分和血清总胆固醇、低密度脂蛋白胆固醇水平显著降低(P<0.05),血清高密度脂蛋白胆固醇水平显著升高(P<0.05),而对照组治疗后上述指标无明显改善(P>0.05).两组不良反应发生率比较,差异无统计学意义善(P>0.05).结论 防风通圣散加减方联合微针导入米诺地尔治疗脾胃湿热型雄激素性脱发疗效确切,安全性较好.

目的 探讨儿童头癣皮肤镜特征性在临床诊疗中的价值.方法 选取 2019 年 1 月—2020 年 12 月本院门诊诊治的 50 例头癣患儿采用回顾性分析,分析比较皮肤镜特征性表现以及不同临床分型之间皮肤镜表现的差异,并观察治疗期间皮肤镜表现的变化情况.结果 唐山地区儿童头癣最常见的临床分型是白癣(64%),儿童头癣的特征性皮肤镜表现包括摩斯码样发(64%)、Z型发(36%)、螺旋样发(30%)和逗号样发(18%),在有以上表现的病发进行取材,真菌镜检阳性率较高.逗号样发是黑点癣的特征性表现.随着治疗时间延长,治疗对真菌镜检结果的影响早于皮肤镜表现的影响,皮肤镜表现的消失与临床痊愈高度一致.结论 皮肤镜特征性表现对儿童头癣的临床分型有一定的提示性作用,可用于儿童头癣的辅助诊断及治疗期间的动态观察.

肢端黑色素瘤(AM)是黑色素瘤的一种亚型,病变分布于手掌、足底和甲床区域.不同人群AM的患病率存在差异,该亚型在白种人群中罕见,而在西班牙、非洲及亚洲人群中较为常见.研究表明,AM约占所有黑色素瘤患者的2％～3％.由于早期AM的临床诊断具有挑战性,且对早期AM缺乏认知这就导致AM患者在诊断时往往处于较晚期.因此,了解早期AM诊断的最新进展至关重要.AM与其他亚型皮肤黑色素瘤相比预后较差,对该疾病的早期认识也有助于制订治疗策略.该综述总结了 AM的流行病学的特点、临床、皮肤镜和组织病理学特征,以期优化早期AM的检测策略提高患者的预后.

Background::The dermoscopic features of rosacea have already been reported. However, the current findings are incomplete, and little is known about phymatous rosacea. Hence, this study aimed to summarize and compare the dermoscopic features and patterns of three rosacea subtypes (erythematotelangiectatic [ETR], papulopustular [PPR], and phymatous [PHR]) in the Chinese Han population and to evaluate whether these features differ with patients’ genders, ages, and durations.Methods::Dermoscopic images of 87 rosacea patients were collected in non-polarized and polarized dermoscopy contact modes at 20-fold magnification. Dermoscopic features, including vessels, scales, follicular findings, and other structures, were summarized and evaluated.Results::The reticular linear vessels and red diffuse structureless areas of ETR were distinctive. For PPR, red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules were typical dermoscopic criteria. The common dermoscopic features of PHR were: orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines. The following features statistically differed among the three rosacea subtypes: reticular linear vessels ( P < 0.001), unspecific linear vessels ( P= 0.005), linear vessels with branches ( P < 0.001), yellow scales ( P = 0.001), follicular plugs ( P < 0.001), perifollicular white color ( P < 0.001), red diffuse structureless areas ( P = 0.022), orange diffuse structureless areas ( P < 0.001), red focal structureless areas ( P = 0.002), orange focal structureless areas ( P = 0.003), white lines ( P < 0.001), follicular pustules ( P < 0.001), and black vellus hairs ( P < 0.001). Conclusions::The dermoscopic patterns of ETR are red diffuse structureless areas and reticular linear vessels. For PPR, the pattern comprehends combinations of red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules. Meanwhile, PHR is characterized by remarkable orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines.

Objective::Dermoscopic evaluation of tumor margins may help to accurately detect lateral borders before surgical excision. The purpose of this study was to comprehensively evaluate the usefulness of dermoscopically detecting basal cell carcinoma tumor margins before surgical excision.Methods::The authors retrospectively analyzed the outcomes of 60 basal cell carcinomas that were excised after undergoing dermoscopic evaluation of the margins from 2016 to 2018 in a single center in Macau SAR, China. Descriptive statistical analysis was carried out by using frequencies and percentages.Results::All treated tumors were completely excised, although five had safety margins of <1 mm. No re-excisions were performed and during a medium follow-up period of 31 months, none of the 60 tumors showed any evidence of recurrence.Conclusions::Our data suggest that the preoperative dermoscopic evaluation of tumor margins increases the chances of successful and complete tumor excision, while preserving healthy adjacent tissue. Further studies comparing dermoscopy-assisted versus conventional excision are needed to better evaluate the value of this technique.

皮肤恶性黑素瘤（MM）是来源于黑素细胞的恶性肿瘤，恶性程度高，进展快，预后差，早期发现可极大提高生存率。皮肤镜作为一种无创检查手段，可提高早期诊断准确率，减少漏诊和误诊，避免盲目活检。本共识总结了不同类型MM的皮肤镜主要表现，并简要概述需要鉴别诊断的疾病，旨在为MM的早期无创诊断提供依据。

Introduction::Nail psoriasis is a type of psoriasis involving nail lesions characterized by pitting, onycholysis, longitudinal ridges, and subungual hyperkeratosis. We herein describe a 9-year-old girl with nail psoriasis who presented with nail crumbling and was treated with topical cream containing 45 μg/g mouse monoclonal antibody to human interleukin -8.Case presentation::A 9-year-old Chinese girl presented with a 6-month history of a rough, thickened fingernail and toenails. Nail plate crumbling, onycholysis, and fissured periungual folds were observed under dermoscopy and ultraviolet dermoscopy. The nails were soaked in warm water, then topical wrapped with Abcream cream overnight. After about 4 months of treatment, the nails significantly improved by both dermoscopy and ultraviolet-dermoscopy evaluattion.Discussion::Due to the different wavelengths of light emitted by polarized light dermatoscope and ultraviolet-dermatoscope, the characteristics of observation will be different. Abcream acts by antagonizing human interleukin -8, inhibiting leukocyte chemotaxis and neovascularization, and regulating the abnormal proliferation and differentiation of keratinocytes.Conclusion::Ultraviolet-dermoscopy is pivotal in evaluating the severity and potency of nail psoriasis. And Abcream can be regarded as a new drug for the treatment of nail psoriasis in children.
