- Abstract
Background: Hair transplantation, particularly through follicular unit extraction (FUE), can lead to postoperative complications, such as numbness, itching, and pain in donor areas, primarily because of delayed wound healing. Efficient management of donor-site healing is crucial to mitigate these complications and improve overall patient outcomes., Objective: This study aimed to assess the efficacy of hair follicular-derived microtissue (HFMT) in promoting wound healing and alleviating postoperative complications in donor areas after FUE hair transplantation., Methods: Perifollicular tissue obtained during the trimming phase of hair transplantation was processed into HFMT and analyzed for its properties using histological and molecular techniques. In a single-blind, split-scalp study involving 98 participants, Group A received HFMT or mupirocin, whereas Group B received HFMT or no treatment. Dermatoscopic images were captured postoperatively, and visual analog scale scores were used to evaluate pain, itching, and numbness., Results: HFMT-treated donor sites in Group A demonstrated a significantly higher wound closure ratio on postoperative day 3 than mupirocin-treated sites. Pain scores for HFMT-treated sites were consistently lower on postoperative days 3, 5, and 7. Similar trends were observed for itching scores. Group B exhibited outcomes comparable with Group A., Conclusion: The application of HFMT homogenates effectively accelerated wound healing and alleviated donor-site complications after FUE hair transplantation., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

- Abstract
Hair disorders, including central centrifugal cicatricial alopecia (CCCA), traction alopecia (TA), and acquired trichorrhexis nodosa (ATN), commonly occur in individuals with curly textured hair. Curly textured hair in individuals of African descent has unique properties and can present diagnostic and therapeutic challenges. CCCA has been linked to uterine leiomyoma and type 2 diabetes mellitus, as well as fibroproliferation. TA often presents with a fringe sign and can arise from high-tension hairstyles presumed to be protective. Trichoscopy is useful in establishing a diagnosis; perifollicular halos are more commonly seen than perifollicular erythema or scale in CCCA. In TA, miniaturized follicles, hair casts, and "flambeau sign" can be seen. Hairstyling practices likely contribute to TA and ATN; however, the data are mixed on the role of chemical relaxers and heat styling in CCCA. Unique considerations in the presentation of frontal fibrosing alopecia in curly textured hair have also been published recently. This review provides a comprehensive, up-to-date summary of these disorders with an emphasis on their unique properties, as well as considerations in hair care for curly textured hair., (© 2024 the International Society of Dermatology.)

- Abstract
Background: Alopecia causes significant distress for patients and negatively impacts quality of life for low-grade glioma (LGG) patients. We aimed to compare and evaluate variations in dose distribution for scalp-sparing in LGG patients with proton therapy and photon therapy, namely intensity-modulated proton therapy (IMPT), intensity-modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), and helical tomotherapy (HT)., Methods: This retrospective study utilized a dataset comprising imaging data from 22 patients with LGG who underwent postoperative radiotherapy. Treatment plans were generated for each patient with scalp-optimized (SO) approaches and scalp-non-optimized (SNO) approaches using proton techniques and photons techniques; all plans adhered to the same dose constraint of delivering a total radiation dose of 54.04 Gy to the target volume. All treatment plans were subsequently analyzed., Results: All the plans generated in this study met the dose constraints for the target volume and OARs. The SO plans resulted in reduced maximum scalp dose (D
max ), mean scalp dose (Dmean ), and volume of the scalp receiving 30 Gy (V30 ) and 40 Gy (V40 ) compared with SNO plans in all radiation techniques. Among all radiation techniques, the IMPT plans exhibited superior performance compared to other plans for dose homogeneity as for SO plans. Also, IMPT showed lower values for Dmean and Dmax than all photon radiation techniques., Conclusion: Our study provides evidence that the SO approach is a feasible technique for reducing scalp radiation dose. However, it is imperative to conduct prospective trials to assess the benefits associated with this approach., (© 2024. Springer-Verlag GmbH Germany, part of Springer Nature.)- Published

- Abstract
Background: Recipient-area perifollicular erythema (RPE) may delay graft growth after hair transplantation. However, there is currently a lack of observational clinical studies of RPE., Objective: To study the clinical features and risk factors associated with RPE while analyzing its correlation with graft growth., Methods: We conducted a multicenter retrospective cohort study between June 2020 and January 2023., Results: A total of 1090 participants were included, 178 (16.33%) showed mild RPE, 56 (5.14%) showed moderate RPE, and 10 (0.92%) showed severe RPE. Patients with RPE had severe hair shaft shedding (P < 0.001) and a lower survival rate (P < 0.001) of grafts. Logistic regression analysis showed that folliculitis is a significant risk factor for mild RPE (OR 6.061, 95% CI 3.343-10.991, P < 0.001) and moderate RPE (OR 3.397, 95% CI 1.299-8.882, P = 0.013). Besides, untimely first postoperative hair washing was associated with the development of moderate RPE (OR 0.724, 95% CI 0.553-0.947, P = 0.018) and severe RPE (OR 1.553, 95% CI 1.156-2.086, P = 0.003)., Conclusion: RPE is a postoperative complication closely related to high hair shaft shedding proportion and low graft survival rate. Both postoperative folliculitis and untimely first postoperative hair washing may induce the occurrence of RPE., Level of Evidence Iii: This journal requires that authors assign a level of evidence to each article.

- Abstract
Alopecia associated with lupus erythematosus is broadly classified into reversible nonscarring alopecia seen in the acute phase, such as worsening of systemic lupus erythematosus (SLE) and cicatricial alopecia seen in chronic cutaneous lupus erythematosus represented by discoid lupus erythematosus (DLE). In DLE-induced alopecia, early therapeutic intervention before developing scarring alopecia is important, but the condition is often resistant to conventional treatment. Anifrolumab (ANI), a novel therapeutic agent for SLE that inhibits Type I interferon activity, has been shown to be effective against acute skin lesions, including alopecia, in patients with SLE. However, there are very few reports on the effect of ANI on alopecia due to DLE. We report on a 27-year-old Japanese woman with SLE whose alopecia due to chronic DLE was refractory to topical therapy and systemic therapy with oral glucocorticoid, multiple immunosuppressants, and belimumab for ∼8 years after onset and whose alopecia improved with ANI. ANI can be considered to be an effective treatment option in lupus patients presenting with alopecia due to DLE, even in the chronic refractory stage., (© Japan College of Rheumatology 2024.

- Abstract
Background: Postburn scarring alopecia on hair-bearing aesthetic subunits causes cosmetic disfiguring and psychological problems. Follicular unit extraction (FUE) hair transplantation is an effective technique for camouflaging postburn scarring alopecia. However, poorly vascularized and fibrotic scar tissue limits the viability of grafts. The mechanical and vascular characteristics of scar tissue can be improved by nanofat grafting. This study aimed to present the results of postburn scarring alopecia treatment using nanofat-assisted FUE hair transplantation., Methods: Eighteen patients who had postburn scarring alopecia in and around the beard were enrolled. Patients underwent single-session nanofat grafting and FUE hair transplantation at 6-month intervals. Twelve months after hair transplantation, the survival rate of transplanted follicular graft, scar improvement, and patient satisfaction were assessed by counting each transplanted follicle individually, using the Patient and Observer Scar Assessment Scale, and using a 5-point Likert satisfaction scale, respectively., Results: Nanofat grafting and hair transplantation were successfully performed without complication. All scars significantly improved in mature characteristics ( P < 0.00001 for patients; P < 0.00001 for observers). The survival and density rates of transplanted follicular units ranged from 77.4% to 87.9% (mean, 83.2% ± 2.5%) and 10.7% to 19.6% (mean, 15.2% ± 2.46%), respectively. All patients reported significantly satisfying cosmetic results ( P < 0.00001)., Conclusions: Scarring alopecia is an inevitable and challenging late complication of deep burned hair-bearing units. Combining nanofat injection and FUE hair transplantation is among the most innovative and effective treatments for postburn scarring alopecia., Clinical Question/level of Evidence: Therapeutic, IV., (Copyright © 2023 by the American Society of Plastic Surgeons.)

- Abstract
Background and Purpose: Radiation-induced alopecia (RIA) is one of the most frequent and upsetting cosmetic side effects after radiotherapy (RT) for brain cancer. We report the incidence of RIA in a cohort of brain tumours patients treated with Proton Therapy (PT) and externally validate published NTCP models of grade 2 (G2) RIA for their implementation in clinical practice., Methods: Data for patients treated for brain tumours with scanning beam PT between 2018 and 2022 were extracted. Acute, late and permanent RIA events were evaluated according to CTCAE 5.0. Lyman-Kutcher-Burman (LKB) and multivariable logistic regression (MLR) published models were computed from the relative dose-surface histogram of the scalp. External validity of models was assessed in terms of discrimination and calibration., Results: In the 264 patients analysed, rates of any grade acute (≤90 days after PT completion), late (>90 days) and permanent RIA (persisting for> 12 months) were 61.8 %, 24.7 % and 14.4 %, respectively. In our independent cohort, LKB- and MLR-NTCP showed a good discrimination for G2 RIA (0.71≤ROC-AUC≤0.83) while model calibration was unsatisfactory possibly due to a different outcome evaluation between training and validation cohorts, as well as differences in clinical and treatment related variables between the two groups., Conclusions: Despite the reasonable sensitivity and specificity of the NTCP models for RIA in the validation cohort, our study emphasizes the significance of differences between the cohorts utilized for model development and validation. Specifically, variations in the reporting of clinical outcomes inevitably jeopardize the validation of NTCP models. A standardize and objective RIA scoring system is essential., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

- Abstract
Introduction and Objective: Photobiomodulation with the use of light-emitting diodes (LEDs) seems to be a promising option for long COVID. This retrospective study evaluates the efficiency of LED irradiation in the treatment of TE in the course of long COVID in patients with and without androgenetic alopecia., Material and Methods: A retrospective single-centre chart review of patients with post-COVID hair loss was performed. 140 patients enrolled to the study were divided into four groups depending on the type of alopecia and treatment: 1) telogen effluvium with LED therapy (TE LED+), 2) telogen effluvium without LED therapy (TE LED-), 3) telogen effluvium and androgenetic alopecia with LED therapy (TE+AGA LED+), and 4) telogen effluvium and androgenetic alopecia without LED therapy (TE+AGA LED-). Clinical and trichoscopic parameters were compared., Results: After 12 weeks, cessation of hair loss and a negative hair pull test were more common in TE LED+ and TE+AGA LED+ in comparison to the patients without LED therapy (p<0.001, p=0.035, respectively). An increased number of thick hairs and an increased number of hairs within follicular units were more common in patients treated with LED irradiation, regardless of the type of alopecia, compared to the patients without LED therapy., Conclusions: The study revealed that LED therapy is safe, well tolerated and seems to be a promising therapeutic option for TE in patients with long COVID. It can be used as adjuvant therapy leading to faster reduction of hair loss, enhancing hair regrowth as well as hair shaft thickness and density.

- Abstract
Telogen effluvium is characterized by excessive hair shedding usually following a stressful event. Ferritin has been used in clinical practice as a biomarker of nonanemic iron deficiency in cases of telogen effluvium. During the years of the COVID19 pandemic, telogen effluvium was reported as a part of post covid manifestations. As ferritin was also a biomarker for inflammation in cases with covid infection, this study was designed to evaluate the value of ferritin in cases with postcovid telogen effluvium one hundred patients recovering from covid 19 for 4-12 weeks were included in the study, detailed drug and laboratory history was obtained and serum ferritin level was measured. the mean serum level of ferritin among telogen effluvium patients was significantly lower than controls (68.52 ± 126 and 137 ± 137.597 ug/L respectively). Patients with telogen effluvium used significantly more azithromycin and ivermectin and significantly less vitamin C, D, lactoferrin and zinc than the controls Although serum ferritin is lower among telogen effluvium patients, it was still higher than the cutoff value for diagnosing nonanemic iron deficiency, we suggest that it will not be a good biomarkers in these cases. Our secondary outcomes showed that dietary supplements used during active infection such as vitamin C, D, lactoferrin and zinc might have a preventive value on postcovid hair loss, while azithromycin and ivermectin could have a negative long term effect on telogen effluvium., (© 2024.

- Abstract
Background and Rationale: Cicatricial alopecia not only affects patients' appearance but also has negative effects on their physical and mental well-being, as well as their daily lives. Therefore, it is essential to provide proactive treatment to patients., Objective: To explore the clinical effects of autologous follicular unit extraction (FUE) transplantation in the treatment of secondary scarring alopecia caused by burn, and to evaluate its effectiveness., Methods: A retrospective observational study has been conducted, which included 41 patients with secondary scarring alopecia caused by burn. All patients underwent initial autologous FUE hair transplantation surgery, and the occurrence of postoperative complications was monitored. Patient satisfaction was evaluated after 12 months post-surgery., Results: Satisfaction assessments were conducted for all 41 patients. Out of the total, 31 individuals expressed being very satisfied, 7 individuals reported being satisfied, and 3 individuals indicated being not very satisfied. Among the patients, 3 experienced complications, including herpes in the donor area for one patient, temporary hair loss for another patient, and thick scab for the third patient., Conclusion: FUE hair transplantation yields positive results for secondary scarring alopecia caused by burn. It offers natural hair growth patterns, minimal trauma, quick recovery, high patient satisfaction, and few complications., (© 2024 The Authors.

- Abstract
Background/aim: Hair-follicle keratinocytes contain high levels of cysteine, which is derived from methionine, rapidly proliferate, and form the hair shaft. The high proliferation rate of hair-follicle keratinocytes resembles that of aggressive cancer cells. In the present study, we determined the effect of a methionine-deficient diet on hair loss (alopecia) in mice with or without homocysteine supplementation., Materials and Methods: Mice were fed a normal rodent diet (2020X, ENVIGO) (Group 1); a methionine-choline-deficient diet (TD.90262, ENVIGO) (Group 2); a methionine-choline-deficient diet with a 10 mg/kg/day supply of homocysteine administered by intra-peritoneal (i.p.) injection for 2 weeks (Group 3). In Group 2, mice were fed a methionine-choline-deficient diet for an additional 2 weeks but with 10 mg/kg/day of i.p. l-homocysteine and the mice were observed for two additional weeks. Subsequently, the mice were fed a standard diet that included methionine. Hair loss was monitored by photography., Results: After 14 days, hair loss was observed in Group 2 mice on a methionine-restricted diet but not in Group 3 mice on the methionine-restricted diet which received i.p. homocysteine. In Group 2, at 2 weeks after methionine restriction, hair loss was not rescued by homocysteine supplementation. However, after restoration of methionine in the diet, hair growth resumed. Thus, after 2 weeks of methionine restriction, only methionine restored hair loss, not homocysteine., Conclusion: Hair maintenance requires methionine in the diet. Future experiments will determine the effects of methionine restriction on hair-follicle stem cells., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

- Abstract
Though it is widely acknowledged that cancer treatments cause hair loss on the scalp, there are limited data on how they affect eyebrow and eyelash hairs. Patients with eyebrow and eyelash loss, or madarosis, seek various treatment options ranging from camouflage techniques with makeup, permanent tattoos, and prescription medications. Though not yet studied in patients with cancer-induced madarosis, techniques such as scalp cooling, cryotherapy, and topical vasoconstrictors are promising preventative options. More robust research is needed to improve both the quality and quantity of available treatment and preventative options. There is a clear need for dermatologists to play a role in supportive oncodermatology for patients who experience eyebrow and eyelash loss secondary to chemotherapy, endocrine therapies, and radiation therapy.

- Abstract
With the rising numbers of patients infected with severe acute respiratory syndrome coronavirus 2, long coronavirus disease 2019 (COVID-19)-a sequelae of COVID-19-has become a major problem. Different sexes and age groups develop different long COVID symptoms, and the risk factors for long COVID remain unclear. Therefore, we performed subgroup analyses of patients with COVID-19, classifying them into different groups. In this multicenter cohort study, using an original questionnaire, we examined patients (≥18 years old) diagnosed with COVID-19 from November 2020 to March 2022 and hospitalized at participating medical facilities. In total, 1066 patients were registered (361 female, 620 male). Hypertension was the most common comorbidity (n = 344; 32.5%). Females with hypertension were significantly less likely to develop long COVID symptoms than those without hypertension (odds ratio [OR] 0.51, 95% confidence interval [CI] 0.27-0.98; p = 0.043). In females, Ca channel blocker administration, rather than having hypertension, was significantly associated with reductions in the frequency of alopecia (OR 0.14, 95% CI 0.03-0.67, p = 0.015), memory impairment (OR 0.14, 95% CI 0.02-0.82, p = 0.029), sleeping disorders (OR 0.17, 95% CI 0.04-0.67, p = 0.012), tinnitus (OR 0.23, 95% CI 0.05-0.98, p = 0.047), sputum (OR 0.31, 95% CI 0.10-0.92, p = 0.035), and fever (OR 0.33, 95% CI 0.12-0.93, p = 0.036). Several long COVID symptoms, including alopecia, were significantly negatively associated with Ca channel-blocker administration in female patients with long COVID. Calcium channel blockers may reduce the development of long COVID in females., (© 2023. The Author(s), under exclusive licence to The Japanese Society of Hypertension.)

- Abstract
Abstact: BACKGROUND: Coronavirus disease (COVID-19) currently named SARS-CoV-2 is a contagious disease caused by a coronavirus; incompatible data are present on the possible relationship among COVID-19 vaccines and hair loss., Aims: The objective of the current study was to assess dermoscopically the prevalence of hair loss among an Egyptian population following COVID-19 vaccination., Methods: A total of 2000 participants were enrolled in this cross-sectional study. Adult males and females who received one of recognized COVID-19 vaccine were included, irrespective of the status of previous COVID-19 infection. Those who were aged less than 18 years or above 60 years were excluded. Furthermore, subjects self-reporting hair loss were assessed by dermoscopy., Results: Among the studied cases, n = 478 (23.9%) complained of hair loss following vaccination. The majority of cases noticed their hair loss during the first 2 months post-vaccination (n = 215 after the first month and n = 158 after the 2nd month respectively)., Conclusion: We reported prevalence of post-vaccination hair fall that was confirmed by trichoscopy and which affected approximately one quarter of participants who received COVID-19 vaccines. Other factors, such as stress and infection, cannot be excluded and remain to be further investigated by larger multicenter studies., (© 2023. The Author(s).)

- Abstract
Background: Smoking-which often refers to recreational consumption of the nicotine-containing tobacco-is deemed a risk factor for both the development of and worsening of androgenetic alopecia (AGA). However, there is no published meta-analysis study on the effect of smoking on AGA; so, we quantitatively synthesized the evidence base pertaining to the recreational activity and this form of hair loss in men., Methods: We systematically searched PubMed and Scopus to identify published studies with suitable data, and pairwise meta-analyses were conducted., Results: Our search identified eight studies-and the data thereof were used across four meta-analyses. We found that ever smokers are significantly (p < 0.05) more likely, than never smokers, to develop AGA (pooled odds ratio (OR) = 1.82, 95% confidence interval (CI): 1.55-2.14). Our results showed that the odds of developing AGA are significantly (p < 0.05) higher in men who smoke at least 10 cigarettes per day, than in their counterparts who smoke up to 10 cigarettes per day (pooled OR = 1.96, 95% CI: 1.17-3.29). For men with AGA, the odds of disease progression are significantly (p < 0.05) higher among ever smokers than in never smokers (pooled OR = 1.27, 95% CI: 1.01-1.60). We found no significant (p ≥ 0.05) association between smoking intensity and disease progression., Conclusions: Findings from the current study-which is the first meta-analysis to our knowledge reviewing the association between AGA and the extent of smoking, can guide further research and update clinical practice guidelines., (© 2024 The Authors.

- Abstract
Introduction Telogen effluvium (TE) is a common sequela of SARS-CoV-2 infection. Existing studies are highly heterogeneous. We aimed to assess the prevalence of TE in a cohort of patients with severe disease hospitalized for acute COVID-19. Methods This prospective cohort study was conducted at the University Clinic of Dermatology, part of the COVID-19 University Hospital Network throughout the pandemic. The acute phase data were extracted from electronic hospital records. Details about hair loss were obtained at two follow-up points, 3 and 6 months after hospital discharge, using telephone interviews. Results A total of 77 patients were successfully followed up, and 40 (48.8%) were male. The mean age was 55.91, SD=10,588. Overall, 68.8% of patients reported TE. Among these, 52.8% reported early onset, and 50.9% reported moderate hair loss. 11 (20.7%) reported complete hair regrowth within three months, and an additional 32 (60.3%) reported complete regrowth within six months. 4 (7.5%) patients have chronic TE. Female sex (p<0.0001), anemia (p=0.019), hypoproteinemia (p=0.037), and severe pneumonia (p=0.004) were associated with TE. Age, fever, SpO2, CRP levels, in-hospital complications, and raised D-dimers were not associated with TE. Discussion Our study confirmed a high prevalence of COVID-19-associated TE in hospitalized patients. Anemia and hypoalbuminemia were associated with TE, shedding new light on the possible pathogenesis. COVID-19-associated TE occurs earlier than classic TE and has a good prognosis in most patients. However, chronic ТЕ was reported by 7.5%. Even a small incidence of long-term sequelae during a pandemic could have substantial health consequences.

- Abstract
Frontal fibrosing alopecia (FFA) is an increasingly common diagnosis, especially in middle-aged women, and has garnered growing attention in the scientific literature. This variant of lichen planopilaris (LPP) is recognized as a progressive scarring alopecia affecting the frontal and temporal regions of the scalp as well as the eyebrows and occasionally other sites. Although its precise etiology remains elusive, various factors such as genetics, medications, hormonal influences, and environmental exposures-including specific chemicals present in sunscreens-have been implicated in its pathogenesis but without evidence of causality. The potential relationship between contact allergy and FFA has been explored, with some suggesting an increased prevalence of contact allergy among patients diagnosed with FFA. This article aims to explore the potential association between contact allergy and FFA, focusing on the current published literature and implicated allergens.

- Abstract
Introduction: Hyperandrogenism is a clinical state consequent to excess androgen production by the ovary, adrenals, or increased peripheral conversion of androgens. The varied manifestations of hyperandrogenism include seborrhea, acne, infertility, hirsutism, or overt virilization of which adult female acne, hirsutism, and female pattern hair loss are of clinical relevance to dermatologists., Areas Covered: We limited our narrative review to literature published during period from 1 January 1985 to Dec 2022 and searched PubMed/MEDLINE, Web of Science (WOS), Scopus, and Embase databases with main search keywords were 'Hyperandrogenism,' 'Female,' 'Biochemical,' 'Dermatological', and 'Dermatology.' We detail the common etiological causes, nuances in interpretation of biochemical tests and imaging tools, followed by an algorithmic approach which can help avoid extensive tests and diagnose the common causes of hyperandrogenism., Expert Opinion: Based on current data, total testosterone, sex hormone binding globulin, DHEAS, prolactin, free androgen index, and peripheral androgenic metabolites like 3-alpha diol and androsterone glucuronide are ideal tests though not all are required in all patients. Abnormalities in these biochemical investigations may require radiological examination for further clarification. Total testosterone levels can help delineate broadly the varied causes of hyperandrogenism. Serum AMH could be used for defining PCOM in adults.

- Abstract
Background: Assess the current and potential indications of photobiomodulation (PBM) therapy and their level of evidence in the prevention or treatment of side effects related to oncology treatments (radiation therapy, and to a minimal extent favored and hematopoietic stem cell transplants). And report on the recommended modalities (parameters and doses) of PBM therapy., Materials and Methods: The Embase, Medline/PubMed, Cochrane, EBSCO, Scopus, and LILACS databases were systematically reviewed to include and analyze publications of clinical studies that evaluated PBM in the prevention or management side effects related to cancer treatments. The keywords used were "photobiomodulation"; "low level laser therapy"; "acute oral mucositis"; "acute dysphagia"; "acute radiation dermatitis"; "lymphedema"; "xerostomia"; "dysgeusia"; "hyposalivation"; "lockjaw"; "bone necrosis"; "osteoradionecrosis"; "radiation induced fibrosis"; "voice and speech alterations"; "palmar-plantar erythrodysesthesia"; "graft versus host disease"; "peripheral neuropathy"; "chemotherapy induced alopecia". Prospective studies were included, while retrospective cohorts and non-original articles were excluded from the analysis., Results: PBM in the red or infrared spectrum has been shown to be effective in randomized controlled trials in the prevention and management of certain complications related to radiotherapy, in particular acute mucositis, epitheliitis and upper limb lymphedema. The level of evidence associated with PBM was heterogeneous, but overall remained moderate. The main limitations were the diversity and the lack of precision of the treatment protocols which could compromise the efficiency and the reproducibility of the results of the PBM. For other effects related to chemo/radiation therapy (dysgeusia, osteonecrosis, peripheral neuropathy, alopecia, palmar-plantar erythrodysaesthesia) and haematopoietic stem cell transplantation (graft versus host disease), treatment with PBM suffers from a lack of studies or limited studies at the origin of a weakened level of proof. However, based on these results, it was possible to establish safe practice parameters and doses of PBM., Conclusion: Published data suggest that PBM could therefore be considered as supportive care in its own right for patients treated with radiation, chemotherapy, immunotherapy, hormone therapy or targeted therapies, whether in clinical practice or clinical trials. therapies. However, until solid data have been published on its long-term safety, the use of PBM should be considered with caution and within the recommended parameters and doses, particularly when practiced in areas of known or possible tumours. In this case, the patient should be informed of the theoretical benefits and risks of PBM in order to obtain informed consent before treatment., (Copyright © 2023 Société Française du Cancer.

Background: The implantation of artificial hair is a successful standardized procedure to restore bald areas or scarred alopecic surfaces of the scalp in both sexes., Materials and Methods: Sebometric measurements were taken, pre, 1, 3, and 6 months postimplant in two symmetric frontotemporal areas of the scalp of seven volunteers to be implanted with 50 units of artificial hair. The artificial hair used in this study are Biofibre 4.0 produced by Medicap srl, Italy., Results: The dermaroller assisted procedure was performed only on one side, and the plain random implant contralaterally for comparison. A marked downregulation of the sebum concentration was observed in the dermaroller treated area 1, 3, and 6 months later in respect to the control side., Conclusion: The dermaroller assisted procedure is safe and effective in reducing the foreign body reaction by the sebaceous glands and the vascular axis injured by the implanting needle; a longer standing success of the implanted hair can thus be achieved reducing the burden of inflammatory reaction., (© 2023 The Authors.

- Abstract
Introduction: The diseases causing chronic diffuse alopecia and having similar clinical findings, namely chronic telogen effluvium, androgenetic alopecia, and the alopecia with overlapping features, should be differentiated. Recently, diffuse variants of lichen planopilaris have been described with histopathologic features of lichen planopilaris but clinically presenting with diffuse hair loss mostly in an androgenetic pattern., Objectives: To determine the accurate diagnosis underlying chronic diffuse alopecia in women by evaluating histopathologic findings., Patients and Methods: The study included 32 patients with diffuse and clinically noncicatricial alopecia for at least 6 months with no identifiable etiologic factor after general medical history, review of organ systems, and appropriate laboratory tests. Two 4 mm punch biopsies, one from vertex and the other from mid-occiput, were obtained and sectioned transversely., Results: The median age was 30.5 years (range: 22-40 years), and the median duration of hair loss was 4 years (range: 1.5-10 years). The histopathologic diagnosis was androgenetic alopecia, chronic telogen effluvium, and overlapping alopecia in 13 (40.6%), three (9.4%), and four (12.5%) patients, respectively. In the remaining 12 (32.5%) patients, a lichenoid inflammatory reaction affecting the infundibulum and isthmus was noted, and the probable diagnosis of diffuse variant of lichen planopilaris was made., Limitations: The retrospective nature and the small sample size., Conclusion: When the clinical diagnosis is not straightforward and no etiologic factor is found, histopathologic examination is mandatory for the accurate diagnosis of the disorder leading to chronic diffuse alopecia in women., (© 2023 the International Society of Dermatology.)

- Abstract
Background: Recipient area scalp necrosis is considered a potential complication of hair transplantation, but has rarely been reported. A small number of patients have developed scalp necrosis after hair transplantation with the widely used Follicular unit excision (FUE) technique. There are no guidelines to prevent and manage this complication. The aim of this study was to provide an insight into the pathogenesis, prevention, and management of scalp necrosis following hair transplantation., Methods: From 2012 to 2021, among more than 10 000 patients who underwent hair transplantation, only three developed scalp necrosis in our clinical experience, besides, one patient transferred to our hospital because of scalp necrosis after undergoing hair transplantation. According to the disease etiology and patients' symptom, a combination of wound management and antimicrobial therapy was employed. This study was approved by the institutional ethics committee of Nanfang Hospital., Results: Of the four patients, three received timely treatment and had a good prognosis. Necrosis became confined and healed within 2-3 weeks. Grafts in the lesion area partially survived. In case 4, due to improper treatment at the early stage, the lesion developed extensively and deeply, which not only delayed wound healing, but also resulted in complete loss of grafts., Conclusion: Preoperative prophylaxis, timely diagnosis, and immediate treatment of scalp necrosis can prevent serious complications and reduce morbidity after hair transplantation., (© 2023 The Authors.

- Abstract
Introduction: trichoscopic and histopathological evaluation of non-scarring systemic lupus erythematosus (SLE) alopecia is uncommon. We aimed to document the prevalence, pattern of hair loss, trichoscopic and histopathologic differences between systemic lupus erythematosus patients with and without hair loss., Methods: this was a cross-sectional comparative study of 75 systemic lupus erythematosus patients, 36 with hair loss from February to December 2020. Trichoscopic evaluation was conducted on all 75 patients. Twenty-three patients (12 with hair loss and 11 without) had scalp biopsies with mucin deposit evaluation. Disease activity was documented using the SLE disease activity index. Data was analyzed using SPSS 22., Results: the mean age of the patients was 33.7 ± 12.4 years. Non-scarring alopecia was observed in 48%. The pattern of hair loss was <4 patches in 44.4%, mild diffuse in 25%, and severe diffuse in 30.6%. Disease activity was mild in 38.9%. Hair shaft changes included thin hair (97.2%), decreased number of hairs per follicular unit (97.2%), hypopigmented hair (85.7%), and follicular red dots (27.8%). Significant differences between the two groups were; a reduction in size and number of sebaceous glands on histopathology, hair shaft, and scalp pigmentary changes in the hair loss group., Conclusion: the prevalence of non-scaring alopecia is high in SLE patients with patchy type as the commonest pattern. Trichoscopic and histopathologic differences exist in SLE patients with and without hair loss and the normal-appearing scalp in SLE patients is involved in the inflammatory process. Hair shaft thinning, hypopigmentation, and scalp pigmentary changes occur in SLE., Competing Interests: The authors declare no competing interests., (Copyright: Ehiaghe Lonia Anaba et al.)

The health of the skin and coat of a cat is connected to the behavioral health of the animal. Stressed animals can cause lesions to their skin and coat such as alopecia, ulcers, and self-mutilation. On the other hand, localized or systemic health problems can cause stress, or pain, and therefore can increase overgrooming and poor skin health. When treating overgrooming and related skin lesions, all the physical and behavioral causes must be addressed through a multimodal approach., Competing Interests: Disclosure No conflict of interest to disclose., (Copyright © 2023 Elsevier Inc.

- Abstract
This article presents a case of a 31-year-old male patient who presented to the outpatient department of the Krasnov Research Institute of Eye Diseases with complaints of diplopia and increased intraocular pressure (IOP) up to 30 mm Hg. The patient had been using minoxidil topically for androgenic alopecia for 8 years. On examination, mild swelling of the bulbar conjunctiva in the upper fornix was revealed; optical coherence tomography showed thinning of the ganglion cell layer, most likely due to moderate myopia. The patient responded well to discontinuation of minoxidil and topical therapy with prostaglandin analogues. After 4 months, an attempt was made to replace topical hypotensive therapy with carbonic anhydrase inhibitors, but the previous hypotensive regimen had to be resumed due to an increase in IOP. During 10 months of observation, no signs of progression were detected according to optical coherence tomography and static perimetry.

- Abstract
Kerion Celsi is an inflammatory, deep fungal infection of the scalp. It is rare in neonates but gets more common in children about 3 years and older. It represents with swelling, boggy lesions, pain, alopecia and purulent secretions. Secondary bacterial infection is not unusual after maceration. Extracutaneous manifestations include regional lymphadenopathy, fever and very rare fungemia. Id-reactions can occur. Diagnosis is based on clinical suspicion, clinical examination and medical history. Diagnosis should be confirmed by microscopy, fungal culture and molecular procedures. The most common isolated fungal species are anthropophilic Trichophyton (T.) tonsurans and zoophilic Microsporum (M.) canis, while geophilic species and moulds rarely cause Kerion Celsi. Treatment is medical with systemic and topical antifungals supplemented by systemic antibiotics when necessary, while surgery needs to be avoided. Early and sufficient treatment prevents scarring alopecia. The most important differential diagnosis is bacterial skin and soft tissue infections., (© 2023 Wiley-VCH GmbH.

- Abstract
Pressure-induced alopecias (PAs) are an infrequent group of scarring and nonscarring alopecias that occur after ischemic obstruction of capillaries that leads to circumscribed areas of hair loss. Initially described after prolonged surgeries or immobilization, type 1 PA occurs after sustained external pressure to the skin, mainly the scalp prominences. Alopecia induced by cosmetic procedures, referred in this review as type 2 PA, is reported with increased frequency in literature and predominantly emerges from pressure exerted by the volume of injectables. It is important to differentiate type 2 PA from vascular occlusion-induced alopecia because they represent distinct entities. Clinically, PA may present with erythema, swelling, and tenderness; however, alopecia might be the sole manifestation. Crusts and ulceration are associated with a worse outcome and a higher risk of scarring alopecia. Prompt diagnosis is paramount to prevent complications. Trichoscopy, although considered nonspecific, may provide relevant clues for an accurate diagnosis. Hair regrows in most cases, but prognosis depends on ischemia severity and timely treatment with reperfusion therapies or mobilization. Treatment of hair loss is usually not necessary because the disease in most cases is self-limited and reversible. The role of topical minoxidil and corticosteroids remains unknown., Competing Interests: Conflicts of interest Dr Tosti is a consultant for DS Laboratories, Monat Global, Almirall, Thirty Madison, Eli Lilly, Bristol Myers Squibb, Procter & Gamble, Pfizer, and Myovant.

- Abstract
There is still a scarcity of data on hair loss caused by coronavirus disease 2019 (COVID-19) infection. This study aims to determine the characteristics of hair loss in Thai individuals after COVID-19 infection and to identify associated factors. From March to June 2022, a retrospective review of medical records and telephone interviews was conducted to determine the details of hair loss, the severity of infection, and the associated treatments of patients with an abrupt onset of hair loss after the diagnosis of COVID-19 infection at Siriraj Hospital in Bangkok, Thailand. This study included 43 patients who experienced hair loss within 4 months after COVID-19 infection. The mean age was 46.5 ± 14.5 years, predominantly women. Most had mild COVID-19 symptoms (59.3%), and 59.1% experienced weight loss, with a mean weight loss of 4.3 ± 2.0 kg per month. Preexisting hair loss was reported in 31.0% of participants, with approximately 3-quarters diagnosed with androgenetic alopecia. The median onset of hair loss after COVID-19 infection was 30 days (interquartile range 30-60). Telogen effluvium was the most common acute hair loss diagnosis, and topical minoxidil was the predominant treatment (95.3%). Female gender was correlated with a more severe shedding scale (adjusted odd ratio 24.76, 95% CI 1.67-168.86). Patients with a history of androgenetic alopecia tended to have a lower hair shedding scale (adjusted odd ratio 0.03, 95% CI 0.01-0.38). This study reviewed the characteristics of hair loss after COVID-19 infection during Omicron outbreaks in Thailand. The COVID-19-associated telogen effluvium, which is the primary cause in our patients, manifested with earlier onset at approximately 30 days., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

- Abstract
Aim: To achieve international expert consensus and give recommendations on best practices in hair transplantation surgery, focusing on pre- and post-transplantation care., Methods: A modified Delphi method was used to reach consensus. An international scientific committee developed an 81-statement questionnaire. A panel of 38 experts in hair transplantation from 17 countries across 4 continents assessed the questionnaire., Results: Two consensus rounds were carried out, with 59 out of 81 statements (73%) reaching consensus. Expert recommendations emphasize the correct selection of candidates for hair transplantation and the need for patients to have received adequate medical treatment for alopecia before transplant. Comorbidities should be assessed and considered while planning surgery, and an individualized plan for perioperative care should be drawn up before transplant. Certain medications associated with increased risk of bleeding should be withdrawn before surgery. Specific recommendations for post-transplantation care are given. After transplantation, patients should gradually resume their normal haircare regimen. Close follow-up should be carried out during the first year after transplant., Conclusions: This study presents numerous consensus-based recommendations on general aspects of hair transplantation, including candidate selection, medical therapy prior to transplantation, anesthesia, and resuming haircare after transplantation.

- Abstract
Background: Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia seen primarily in women of African descent but rarely reported in men. The etiology of CCCA is unknown, but genetic variants, type 2 diabetes mellitus, and bacterial infections may play a role., Objectives: We aimed to characterize the demographics, medical histories, and clinical findings of male patients with CCCA with the hypothesis that features may differ from women., Methods: This was a case series of adult male patients with biopsy-confirmed CCCA seen at an academic dermatology department between 2012 and 2022., Results: In total, 17 males had a scalp biopsy and clinical findings consistent with CCCA. The average age was 43 years, and 88.2% of cases identified as Black race. Scalp pruritus was the most common symptom, and few patients endorsed high-risk hair care practices. None of the cases had diagnosis of type 2 diabetes mellitus, but 17.6% had history of latent tuberculosis, and 47.1% had a positive family history of alopecia. We observed 8 patients with atypical CCCA, and 29.4% had an overlapping scalp diagnosis., Limitations: This study is limited by the single center, retrospective design and small sample size., Conclusions: It is important to consider CCCA in the differential diagnosis of alopecia in adult Black males., Competing Interests: Conflicts of interest None disclosed., (Copyright © 2023 American Academy of Dermatology, Inc.
