Recent studies have reported an apparent dualistic nature of RF devices for hair, causing either removal or growth depending on the modality of RF.Materials and methods: PubMed/MEDLINE and Web of Science searches were conducted in July 2022 according to PRISMA guidelines for studies discussing RF technology in hair applications (n = 19).Results: The majority of studies describe the utility of RF devices in removal of unwanted hair (n = 15). Bipolar RF has been used in combination with intense pulsed light for effective long-term removal of body and facial hair. The chromophore-independent method of energy delivery in RF makes it a viable add-on therapy for treating lighter colored hair and darker Fitzpatrick skin types. Monopolar RF is used for eyelash removal in patients with trichiasis. In contrast, fractional RF has been used to stimulate hair growth in patients with alopecia areata and androgenetic alopecia.Conclusions: Preliminary evidence supports the use of bipolar and monopolar RF devices for hair removal, while fractional RF appears to be an emerging technology for hair growth. Additional studies are needed to investigate the efficacy, mechanisms, and parameters of radiofrequency devices for various hair applications.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"9 3","pages":"169-178"},"PeriodicalIF":1.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10264903/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9654500","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}

Onychomycosis is primarily caused by dermatophytes and affects around 5.5% of the population worldwide. Yet, only limited data exist on the associations between the HLA system and onychomycosis. Thus, the objective of the study was to investigate if there is an association between HLA alleles and onychomycosis.Methods: Participants in the Danish Blood Donor Study were defined as cases of onychomycosis and controls based on antifungal prescriptions in the national prescription registry. Associations were investigated using logistic regressions adjusted for confounders and were Bonferroni corrected for multiple tests.Results: A total of 3,665 participants were considered onychomycosis cases, and 24,144 participants were considered controls. We found two protective HLA alleles of onychomycosis: DQB1*06:04, odds ratios (OR) 0.80 (95% confidence interval (CI) 0.71-0.90), and DRB1*13:02, OR 0.79 (95% CI: 0.71-0.89).Conclusion: The finding of two novel protective alleles of onychomycosis indicates that certain HLA alleles have certain antigen presentation properties affecting the risk of fungal infection. These findings may provide the basis for future research identifying immunologically relevant antigens of fungi causing onychomycosis, which could ultimately lead to targets of new drugs with antifungal effects.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"9 3","pages":"195-202"},"PeriodicalIF":1.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10264904/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9654502","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 has been long reported that darker skinned ethnicities have a higher prevalence of longitudinal melanonychia in the US population (e.g., African Americans with 77% prevalence) [Indian J Dermatol. 2021;66(4):445], but unfortunately, there are limited studies exclusively looking at longitudinal melanonychia in pediatric patients of color.Case presentation: In this case series, we review the current literature and report the findings of 8 cases of longitudinal melanonychia in children with skin types IV or greater. Out of the 8 cases identified, only 4 returned to the clinic for monitoring (n = 4), and there was an average of 20.8 months between the initial and final visits. Of the patients that returned for follow-up, 2 showed no relevant changes in the nail pigmentation, 1 showed fading of the band, and 1 patient showed enlargement of the band to involve the whole nail.Conclusion: Although many sources recommend a conservative approach to treatment that involves monitoring and follow-up, our findings indicate that a wait-and-see method cannot be applied to all cases in the pediatric population due to disruptions in continuity of care. An individualized approach considering such factors should be employed for each patient, and certain high-risk features of the ABCDEF nail melanoma model may be relevant in pediatric cases.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"9 3","pages":"224-229"},"PeriodicalIF":1.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10264910/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9654503","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}

Amyloidoma is a localized tumoral deposit of amyloid in the absence of systemic amyloidosis, and it has been described in different anatomic sites. We report two cases of amyloidoma in the nail unit and provide insights into this recently described entity.Case presentation: Both cases presented as an asymptomatic, slowly growing nodule underneath the distal nail bed of a toe with associated onycholysis. Histopathology was characterized in both patients by the presence of deposits of Congo red-positive, homogeneous, amorphous, and eosinophilic material within the dermis and subcutaneous tissue admixed with aggregates of plasma cells. In both cases, an extensive workup excluded systemic amyloidosis. Treatment was based on local excision, and no local recurrence or progression to systemic amyloidosis was observed at 1 year of follow-up.Conclusion: These are the first reports of amyloidomas of the nail unit. The clinical and histopathological presentations parallel those of an amyloidoma affecting the skin. Local excision seems to be an efficient treatment modality, but long-term follow-up is warranted in order to exclude recurrence, an associated marginal B-cell lymphoma, or progression to systemic amyloid L amyloidosis.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"9 3","pages":"216-220"},"PeriodicalIF":1.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10264914/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9656533","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}

The prevalence of thyroid disorders was 12% and of hypothyroidism 10.7%. Patients with thyroid disorders were more likely to have a BMI ≥25 (p = 0.016), asthma (p = 0.034) and to be nonsmoker (p = 0.018) or ex-smoker (p = 0.017). Binary logistic regression showed that only asthma and nonsmoking were associated with thyroid disorders or hypothyroidism among patients with HS.Conclusion: Our study is in line with previous ones that showed the association of HS and thyroid disorders in nonsmokers. Asthma may be simply an association with thyroid disorders and unrelated to HS as such.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"9 3","pages":"191-194"},"PeriodicalIF":1.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10264902/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9660554","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}

They mostly affect young-to middle-aged women, but rarely they may also occur in the elderly, requiring generally no specific treatment.Case presentation: We present the case of a 76-year-old woman with sudden onset of ES. Clinical examination evidenced brown-to-orange papules and plaques on the anterior neck, corresponding dermatoscopically to orange-brownish structureless areas, with barely hinted peripheral incomplete network, superimposed on areas of light pink. Histology showed dermal proliferation of epithelial cells forming cords and ductules, confirming the clinical-dermoscopic suspect of ES. The lesions remained stable at 12-month follow-up without treatment.Discussion: This case highlights the role of dermoscopy to help differentiate ES from other clinically similar but more serious entities, such as histiocytosis, mastocytosis, and lichen planus, and to schedule the required confirmatory biopsy in due time without haste.","PeriodicalId":21844,"journal":{"name":"Skin Appendage Disorders","volume":"9 2","pages":"144-146"},"PeriodicalIF":1.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10015645/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9144051","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}
