Background: Alopecia areata (AA) is an autoimmune disease characterized by peribulbar lymphocytic infiltration, follicular miniaturization, catagen/telogen follicles, and increased follicular stelae (streamers) in skin biopsies.

Objectives: Our aim was to assess the number of follicular stelae of patients with AA and to evaluate their association with clinical type and severity and treatment response of AA.

Materials and methods: Histopathologic features including the number of follicular stelae were recorded in skin biopsies taken from lesions of AA in 142 patients who attended our dermatology clinic from 2011 to 2017.

Results: There was a statistically significant correlation between patient age and the number of follicular stelae (P = 0.001). There was a statistically significant correlation between the severity of disease and number of follicular stelae (P = 0.005). AA subtypes (0%-25% scalp hair loss) had a significantly lower number of follicular stelae than 75%-100% of scalp hair loss and alopecia universalis (7.92 ± 4.21 vs. 13.23 ± 7.28). There was no statistically significant correlation between treatment response and the number of follicular stelae (P = 0.75).

Conclusion: Our results showed that the number of follicular stelae varied among AA clinical types and correlated with severity. This study was the first to evaluate the correlation between the number of follicular stelae and severity of AA.

背景:斑秃(AA)是一种自身免疫性疾病,其特点是毛囊周围淋巴细胞浸润、毛囊萎缩、毛囊变性/变性以及皮肤活检中毛囊干(茎)增多:我们的目的是评估AA患者的毛囊支架数量,并评价其与AA临床类型、严重程度和治疗反应的关系。材料与方法:我们记录了2011年至2017年期间在皮肤科门诊就诊的142名AA患者的皮肤活检组织病理学特征,包括毛囊支架数量:患者年龄与毛囊干基数量之间存在统计学意义上的显著相关性(P = 0.001)。疾病严重程度与毛囊干细胞数量之间存在统计学意义上的显著相关性(P = 0.005)。AA亚型(0%-25%头皮脱发)的毛囊干细胞数量明显低于75%-100%头皮脱发和普秃(7.92 ± 4.21 vs. 13.23 ± 7.28)。治疗反应与毛囊干细胞数量之间没有统计学意义上的相关性(P = 0.75):我们的研究结果表明,毛囊干细胞的数量在不同的 AA 临床类型中存在差异,并且与严重程度相关。本研究首次评估了毛囊支架数量与 AA 严重程度之间的相关性。

Lower leg hair removal is the method of reducing unwanted lower leg hair. Various technologies for lower leg hair removal include Intense Pulsed Light (IPL), alexandrite laser, and neodymium-doped yttrium aluminum garnet (Nd: YAG) laser. Conventional techniques are abandoned because effectiveness of the latest technological therapies has a longer period with minimal side effects. The comparison of successful treatment among IPL, alexandrite laser, and Nd: YAG laser for lower leg hair removal. Two patients, male and female, 28 years old, Fitzpatrick IV skin type. Three areas in the lower legs are marked for IPL 695 nm, fluence 15 J/cm2, pulse duration 60 ms; alexandrite 755 nm, fluence 3 J/cm2, pulse duration 2 ms, long-pulsed Nd: YAG 1064 nm, fluence 32 J/cm2, pulse duration 60 ms. IPL for 3 sessions at 2-week intervals. The alexandrite and Nd: YAG lasers for 3 sessions at 4-week intervals. Successful parameters with hair reduction and Visual Analog Scale (VAS) can be seen from photography and dermoscopy before and after therapy. In the first case, the most effective reduction terminal hair after IPL (95,1%), alexandrite (91,02%) and Nd: YAG (79,69%), respectively. In the second case, the most effective reduction of terminal hair after alexandrite (91,02%), Nd: YAG (79,69%), and IPL (20%), respectively. Hyperpigmentation and the highest VAS score (6-7) are found in the area treated with alexandrite lasers of two patients. Two patients have decreased Dermatology Life Quality Index scores. Nd: YAG laser may be better suitable for both sexes with minimal side effects. The limitation of this study is the smaller subject group and limited session.

小腿脱毛是一种减少多余小腿毛发的方法。小腿脱毛的各种技术包括强脉冲光(IPL)、翠绿宝石激光和掺钕钇铝石榴石(Nd:YAG)激光。由于最新技术疗法的有效期更长,副作用最小,因此传统技术已被摒弃。比较强脉冲光、紫翠玉激光和掺钕钇铝石榴石(Nd: YAG)激光对小腿脱毛的成功治疗效果。两名患者,男女,28 岁,菲茨帕特里克 IV 型皮肤。小腿的三个区域分别标记为:IPL 695 nm,能量 15 J/cm2,脉冲持续时间 60 ms;翠绿宝石 755 nm,能量 3 J/cm2,脉冲持续时间 2 ms;长脉冲 Nd:YAG 1064 nm,能量 32 J/cm2,脉冲持续时间 60 ms。IPL 3 次,每次间隔 2 周。紫翠宝石激光和 Nd: YAG 激光 3 次,每次间隔 4 周。从治疗前后的照片和皮肤镜可以看出,成功的参数包括毛发减少量和视觉模拟量表(VAS)。在第一个病例中,IPL(95.1%)、翠绿宝石(91.02%)和 Nd: YAG(79.69%)分别最有效地减少了末端毛发。在第二种情况中,紫翠宝石(91.02%)、Nd:YAG(79.69%)和 IPL(20%)分别最有效地减少了末端毛发。两名患者接受紫翠宝石激光治疗的部位出现色素沉着,VAS评分最高(6-7 分)。两名患者的皮肤科生活质量指数评分下降。掺钕钇钕石榴石(Nd: YAG)激光可能更适合男女患者,且副作用最小。这项研究的局限性在于受试者人数较少且疗程有限。

Alopecia areata (AA) is an autoimmune disorder leading to nonscarring hair loss of the scalp and/or body. Atypical hair regrowth in AA is considered a rare phenomenon. Many paradoxical forms of hair regrowth have been described in AA. Targetoid hair regrowth pattern in AA was first described in 1988. Here, we report three cases wherein this pattern of hair regrowth was seen.

斑秃(AA)是一种自身免疫性疾病,会导致头皮和/或身体非疤痕性脱发。非典型毛发再生被认为是一种罕见现象。在 AA 中已描述了许多矛盾的毛发再生形式。1988年首次描述了AA患者的 "靶状 "毛发再生模式。在此,我们报告了三例出现这种毛发再生模式的病例。

Androgenic alopecia (AGA) and alopecia areata (AA) are two highly prevalent conditions, affecting both men and women of a wide range of ages, which strongly impact their quality of life and self-esteem. Both pathologies are deemed to be reversible, although conventional therapies have shown limited scope and efficacy. New therapeutic approaches, focusing on the degenerative changes that take place in the hair follicle, are needed to achieve better outcomes. For instance, adipose-derived stem cells (ADSC), abundant and easy to obtain, hold great potential in follicular regeneration. ADSCs can be isolated as stromal vascular fraction (SVF) by the enzymatic digestion of the lipoaspirate or as nanofat by the mechanical breakdown of adipocytes. In addition, commercial preparations of the conditioned medium of the ADSCs secretome (ADSC-conditionate medium [CM]) have entered the market as an appealing alternative because of their comparatively lower cost and accessibility. A search was conducted, crossing relevant terms, on PubMed Central and Google Scholar. Criteria for inclusion were studies in the past 10 years on humans with AGA or AA, where either SVF, nanofat, or ADSC-CM was tested as the main treatment. Eleven publications qualified: two studied nanofat, three, ADSC-CM, and six, SVF, either individually or in combination with other therapies. Only one randomized controlled trial (RCT) was found and classified as evidence 2b according to the Sackett scale. The rest were case-control studies or case series with small samples and no control, graded as evidence 3b and 4. A meta-analysis could not be conducted due to the heterogenicity of the study designs. Given the evidence obtained, Level D NICE recommendation was established. However, we consider that the positive findings are sufficiently consistent to support the elaboration of further RCTs that share criteria and methods.

雄激素性脱发(AGA)和斑秃(AA)是两种发病率很高的疾病,影响着不同年龄段的男性和女性,严重影响他们的生活质量和自尊。虽然传统疗法的范围和疗效有限,但这两种病症都被认为是可逆的。要想取得更好的治疗效果,就必须采用新的治疗方法,重点关注毛囊中发生的退行性变化。例如,脂肪来源干细胞(ADSC)数量丰富且易于获取,在毛囊再生方面具有巨大潜力。脂肪干细胞可通过酶解吸脂液分离为基质血管部分(SVF),或通过机械分解脂肪细胞分离为纳米脂肪。此外,ADSCs分泌组条件培养基(ADSC-conditionate medium [CM])的商业制剂也已进入市场,因其成本相对较低且容易获得,成为一种有吸引力的替代品。我们在 PubMed Central 和 Google Scholar 上使用相关术语进行了搜索。纳入标准是过去 10 年中针对 AGA 或 AA 患者的研究,其中 SVF、纳米脂肪或 ADSC-CM 均作为主要治疗方法进行了测试。符合条件的出版物有 11 篇:其中 2 篇研究了纳米脂肪,3 篇研究了 ADSC-CM,6 篇研究了 SVF,这些研究或单独进行,或与其他疗法相结合。其中只有一项随机对照试验(RCT)符合条件,并根据萨基特量表被列为证据 2b。其余均为病例对照研究或病例系列研究,样本较少且无对照,被评为证据 3b 和 4。由于研究设计的异质性,无法进行荟萃分析。鉴于所获得的证据,NICE 建议定为 D 级。然而,我们认为积极的研究结果具有充分的一致性,足以支持制定更多具有相同标准和方法的 RCT。

Trichotillomania is nonscarring alopecia with recurrent pulling out of one's hair and repeated attempts to reduce hair pulling. Clinical improvement in the urge to pull out hairs in trichotillomania is often not quantifiable and based on unreliable history. Here, we present a case of trichotillomania with follow-up features on trichoscopy during treatment. By this, we propose trichoscopy as an objective tool to visualize clinical improvement in the urge to pull out hairs and assess treatment efficacy.

拔毛症是一种非瘢痕性脱发,患者会反复拔掉自己的头发,并反复尝试减少拔毛。临床上,嗜毛症患者拔毛冲动的改善往往无法量化,而且病史也不可靠。在此,我们介绍一例在治疗过程中通过毛发镜检查发现随访特征的毛发妄想症患者。因此,我们建议将毛发镜检查作为一种客观工具,用于观察拔毛冲动的临床改善情况并评估治疗效果。

Introduction: Follicular psoriasis is one of the underdiagnosed clinical types of psoriasis. Literature is grossly limited to anecdotal case reports and series. Clinical and investigational aspects are not studied in depth.

Materials and methods: A study was conducted to determine the frequency of follicular psoriasis, which includes cases with an exclusive or substantial number of follicular lesions. We analyzed the clinical, dermoscopic, and histopathological features of follicular psoriasis in a descriptive study.

Results: A total of 117 patients with psoriasis were screened. An exclusive or substantial number of follicular lesions were found in 22 patients. Four patients had exclusively follicular lesions and others were psoriasis vulgaris with follicular psoriasis. Dermoscopy revealed perifollicular scaling and white homogeneous area with normal terminal hair in all cases. Vascular features were visible in 14 cases and all had dotted vessels, with four having additional globules. Twenty patients revealed one or more features suggestive of follicular psoriasis on histopathology.

Conclusion: Follicular lesions can appear exclusively or can coexist with plaque type of lesions in psoriasis. They may indicate early psoriasis lesions.

简介毛囊性银屑病是临床诊断不足的银屑病类型之一。文献资料严重局限于传闻病例报告和系列报道。材料和方法:我们进行了一项研究,以确定毛囊性银屑病的发病率,其中包括完全或大量毛囊性皮损的病例。我们在一项描述性研究中分析了毛囊性银屑病的临床、皮肤镜和组织病理学特征:结果:共筛选出 117 名银屑病患者。结果:共筛查出 117 名银屑病患者,其中 22 名患者完全或大量存在毛囊性皮损。四名患者仅有毛囊性皮损,其他患者则是寻常型银屑病合并毛囊性银屑病。皮肤镜检查显示,所有病例均有毛囊周围脱屑和白色均匀区,毛发末端正常。14 例患者可见血管特征,所有病例都有点状血管,其中 4 例有额外的球状血管。20 例患者在组织病理学检查中发现一种或多种提示毛囊性银屑病的特征:结论:银屑病的毛囊性皮损可单独出现,也可与斑块型皮损并存。它们可能预示着早期银屑病病变。皮肤镜是确诊毛囊性银屑病的有效而快速的工具。组织病理学虽然可以确诊,但需要高明的解释技巧。毛囊性银屑病的诊断可能具有治疗意义。

Introduction: Alopecia totalis (AT) and Alopecia universalis (AU) are forms of Alopecia areata (AA) which represent the strongest predictor of poor prognosis since spontaneous regrowth is <10%. Topical immunotherapy agent, diphenylcyclopropenone (DPCP) has shown clinical efficacy with limited side effects in severe forms of AA. However, its specific role in AT/AU characterized by complete hair loss over the scalp can help highlight the efficacy of the drug with fewer confounders.

Methodology: Data were collected from 18 patients diagnosed with AT/AU and treated with topical immunotherapy with DPCP as per protocol by Happle et al. Baseline Severity of Alopecia Tool (SALT) score and subclass was recorded. In the case of AU, baseline body hair loss score was also recorded. Patients were reassessed after 6 months of treatment in terms of change in SALT score and hair regrowth was assessed using the Global Assessment Score. The side effects during treatment were also assessed and recorded.

Results: Eighteen patients of whom eleven (61.1%) were diagnosed as AU and seven (38.9%) as AT were treated. The mean age was 21.6, with a male: female ratio of 3:2. The comorbidities noted were atopy in six (33.3%), atopy and hypothyroidism in one (5.5%), Down's syndrome in two (11.1%), and hypothyroidism alone in one (5.5%) patient. The mean duration of disease at the time of presentation was 3 years and all patients had remained refractory to various other modalities of treatment. All patients had a baseline SALT score of 100 corresponding to S5. After 6 months of treatment, 27.7% of patients did not show any response (SALT score S5), 16.6% had a score of S4, 11.1% had a score of S3, 11.1% had a score of S2, 22.2% had a score of S1, and 11.1% had a score of S0. On assessing improvement in body hair loss score, 36.3% of patients showed no improvement, 36.3% showed partial improvement, and 27.2% of patients showed complete body hair regrowth. About 55.5% of patients developed notable side effects that included severe local reactions, cervical lymphadenopathy, acne and pigmentation at the site of application as well as untreated sites.

Conclusion: The AT/AU subtypes of AA, was amenable to treatment with contact immunotherapeutic agent DPCP with a >75% hair regrowth in 33.3% of patients. The castling phenomenon was seen in 63.6% of AU patients. The adverse effects noted were not severe enough to deter treatment.

导言:全秃(AT)和普秃(AU)是斑秃(AA)的一种形式,是预后不良的最有力的预测指标,因为自发再生是方法学的一种:根据 Happle 等人的方案,收集了 18 名被诊断为 AT/AU 并接受 DPCP 局部免疫疗法治疗的患者的数据。对于AU患者,还记录了基线体毛脱落评分。治疗 6 个月后,根据 SALT 评分的变化对患者进行重新评估,并使用总体评估评分对毛发再生情况进行评估。此外,还对治疗期间的副作用进行了评估和记录:18名患者接受了治疗,其中11人(61.1%)被诊断为AU,7人(38.9%)被诊断为AT。平均年龄为 21.6 岁,男女比例为 3:2。6名患者(33.3%)患有过敏症,1名患者(5.5%)患有过敏症和甲状腺功能减退症,2名患者(11.1%)患有唐氏综合征,1名患者(5.5%)仅患有甲状腺功能减退症。患者发病时的平均病程为 3 年,所有患者均对其他各种治疗方法无效。所有患者的基线 SALT 评分均为 100 分,相当于 S5。治疗 6 个月后,27.7% 的患者没有任何反应(SALT 评分为 S5),16.6% 的患者评分为 S4,11.1% 的患者评分为 S3,11.1% 的患者评分为 S2,22.2% 的患者评分为 S1,11.1% 的患者评分为 S0。在评估体毛脱落评分的改善情况时,36.3% 的患者没有改善,36.3% 的患者有部分改善,27.2% 的患者体毛完全再生。约 55.5%的患者出现了明显的副作用,包括严重的局部反应、颈部淋巴结病、痤疮和用药部位及未治疗部位的色素沉着:结论:AT/AU 亚型 AA 适合使用接触性免疫治疗剂 DPCP 治疗,33.3% 的患者毛发再生率大于 75%。63.6%的AU患者出现了秃顶现象。不良反应并不严重,不足以阻止治疗。

Introduction: Androgenetic alopecia (AGA) is a progressive loss of terminal hairs in a specific pattern distribution related to androgen. The dermoscopy of hair and scalp, known as trichoscopy, is a noninvasive method for diagnosing alopecia and other hair and scalp disorders.

Objective: This study aims to report the correlation between the severity of males with AGA based on Hamilton-Norwood's scale with the clinical characteristics found in trichoscopy.

Materials and methods: This study included 40 patients aged 25-58 years who visited the dermatology outpatient clinic in a tertiary health facility in Indonesia. Clinical diagnosis was determined through history taking, physical examination, and trichoscopy. Based on Hamilton-Norwood's criteria, patients were divided into two groups: early and late stage. Parameters examined in trichoscopy include yellow dots, white dots, peripilar sign, vellus hair, hair diameter diversity, single-hair follicles, and empty follicles. The Chi-square test and Fisher's exact test were used to analyze the statistical significance between the groups.

Results: All participants presented with hair diameter diversity, vellus hair, and empty follicles (100%). None of the study participants had yellow dots. White dots and single-hair follicles were seen in 32 (80%) and 30 cases (75%), respectively. In the late-stage group, these features were more prevalent. Peripilar sign was found in 25 participants (62.50%), and it was more common in the early-stage group. No significant association was found between disease severity and trichoscopy features.

Conclusion: The most common trichoscopy findings in particular order were hair diameter diversity, vellus hair, and empty follicles, followed by white dots, single-hair follicles, and peripilar signs. No significant association between alopecia severity and trichoscopy parameters was observed. Studies with a larger number of participants, including a control group, should be conducted to yield more significant results.

导言:雄激素性脱发(AGA)是一种进行性末端毛发脱落,其分布模式与雄激素有关。对头发和头皮进行皮肤镜检查,即毛囊镜检查,是诊断脱发及其他头发和头皮疾病的一种非侵入性方法:本研究旨在报告根据汉密尔顿-诺伍德量表得出的男性 AGA 严重程度与毛发镜检查发现的临床特征之间的相关性:研究对象包括在印度尼西亚一家三级医疗机构皮肤科门诊就诊的 40 名患者,年龄在 25-58 岁之间。通过病史采集、体格检查和毛囊镜检查确定临床诊断。根据汉密尔顿-诺伍德标准,患者被分为两组:早期和晚期。毛发镜检查的参数包括黄点、白点、毛周征、绒毛、毛发直径多样性、单发毛囊和空毛囊。采用卡方检验(Chi-square test)和费雪精确检验(Fisher's exact test)分析各组之间的统计学意义:所有参与者都有头发直径多样性、单发毛囊和空毛囊(100%)。没有人出现黄点。白点和单发毛囊分别出现在 32 例(80%)和 30 例(75%)中。在晚期组中,这些特征更为普遍。25名参与者(62.50%)发现了毛周征象,这种征象在早期组中更为常见。疾病严重程度与三镜检查特征之间无明显关联:结论:最常见的毛囊镜检查结果依次是毛发直径多样性、绒毛和空毛囊,其次是白点、单发毛囊和毛周征象。脱发严重程度与毛囊镜检查参数之间没有明显关联。应进行更多参与者(包括对照组)的研究,以获得更显著的结果。
