However, there is limited information on the distribution of the microscopic characteristics.Objective: This study evaluated the microscopic morphological characteristics of pulled-out hair and their correlation with disease course in AA.Methods: Morphological characteristics of pulled-out hair were classified into 5 categories: the presence of typical clubbing, surface undulation, tapering, breakage, and depigmentation in proximal hair shaft. Clinical course of AA was investigated through assessment of Severity of Alopecia Tool (SALT) score (initial score, maximal score and difference of them [ΔSALT]).Results: Among 1,272 pulled-out hairs (n=179) obtained at initial visit, depigmentation (59.5%) was the most common, followed by loss of typical clubbing (57.2%) and surface undulation (55.2%). The percentage of loss of typical clubbing and proximal tapering was significantly higher in severe type of AA, younger age of onset and shorter disease duration. The ratio of typical clubbing (<50% vs. ≥50%) was associated with difference in maximal score and ΔSALT (p<0.05). Strong activity group (pulled-out hair ≥10, n=33) showed difference in clinical course (maximal score, ΔSALT) as well as distribution of microscopic features (loss of typical clubbing) compared with those in non-strong activity group. The ratio of typical clubbing significantly increased at follow-up than initially in strong activity group (p<0.05).Conclusion: Microscopic hair morphology, especially loss of typical clubbing and proximal tapering, could be useful tool to predict the course of AA.","PeriodicalId":94298,"journal":{"name":"Annals of dermatology","volume":"36 1","pages":"29-34"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10861307/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139704387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is often reported to be worsened by psychological stress.Objective: To explore the role of psychological stress and related triggers in AD, and its connection to worsening of this disease, focusing on patients' perspectives.Methods: In total, 28 patients with AD were included in focus groups. Topics regarding psychological stress and psychological triggers were discussed.Results: The hypothesis that psychological stress may have impact on eczema and its pruritus was supported by all of the patients. Distinguishing the worsening effect of psychological stress from effects of physiological triggers, such as infection, climate and allergic factors, was claimed to be difficult by many patients. Most of the patients thought that chronic stress affected the AD more when compared to acute stress. Family problems, financial problems, work overload, school exam periods, lack of structure at work, and unforeseen events were identified as important psychological triggers. Conventional treatment/therapy with topical corticosteroids and emollients, UV light treatment, were suggested as possible treatments, as well as psychological intervention and physical exercise.Conclusion: Psychological stress is an important factor to consider in the management of patients with AD. In particular, chronic stress tends to worsen AD. The type of stress can possibly also affect the quality of the pruritus experienced by the patients. Unforeseen events and decision making were frequently mentioned as important triggers. Furthermore, physical exercise was reported to provide beneficial effects.","PeriodicalId":94298,"journal":{"name":"Annals of dermatology","volume":"35 5","pages":"342-347"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/5d/eb/ad-35-342.PMC10579569.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41224661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Periorbital wrinkles are attributed to long-term, repeated use of orbicularis oris muscles and UV-induced dermal collagen degeneration. Fractional microneedle radiofrequency (RF) treats scars and laxity by creating vertical channels of injury in the dermis, triggering a scarless healing cascade and neocollagenesis.Objective: To evaluate the effect and safety of a novel fractional microneedle RF device on periorbital wrinkles based on several objective indicators.Methods: Eleven healthy Korean patients aged 30 to 75 years with periorbital wrinkles were included in this study. Wrinkle grades were evaluated using the Fitzpatrick wrinkle assessment scale (WAS). The melanin and erythema index, transepidermal water loss (TEWL), and three parameters for elasticity were recorded. Skin biopsies were obtained in patients who consented.Results: All patients exhibited wrinkle improvement in the lateral periorbital area, and two patients also showed efficacy in the lower eyelid area. There was a statistically significant decrease in WAS and a significant improvement in the melanin index of V4 and V5. TEWL also showed a considerable decline on V4 and V5, suggesting that the water content of the skin increased with repeated laser sessions. A peak increase in viscoelasticity and a decrease in retraction time following the first laser application were observed. In the histopathologic examination, the dermis had a denser collagen and elastin content.Conclusion: Microneedle fractional RF resulted in statistically significant long-term clinical improvement of periorbital wrinkles and enhanced pigmentation and skin hydration.","PeriodicalId":94298,"journal":{"name":"Annals of dermatology","volume":"35 5","pages":"360-366"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/20/f1/ad-35-360.PMC10579575.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41224660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is roughly divided into segmental and non-segmental vitiligo, and it has been found that abnormalities of melanocytes themselves and dysregulation of autoimmune responses to melanocytes are greatly involved in the pathology of non-segmental vitiligo. Segmental vitiligo pathology is largely unknown; however, it has been suggested that it may be caused by skin or melanocyte mosaicism. Treatments for vitiligo include topical therapy, ultraviolet therapy, and surgical transplantation, and it is extremely important to correctly understand the pathology to perform optimal treatment. In recent years, the development of vitiligo treatments using Janus kinase (JAK) inhibitors has progressed rapidly. We herein outline the latest pathology of vitiligo, from general vitiligo treatment to the progress of clinical trials using JAK inhibitors, along with what clinicians should consider in archiving precision medicine, including my own ideas thereon.","PeriodicalId":94298,"journal":{"name":"Annals of dermatology","volume":"35 5","pages":"333-341"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/62/ee/ad-35-333.PMC10579571.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41224662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
