Frontal fibrosing alopecia (FFA) is an inflammatory cicatricial alopecia, which is considered to be a variant of lichen planopilaris. In addition to follicular changes, FFA often presents with associated cutaneous manifestations in most patients, including lichen planus pigmentosus, implantation line hypochromia and facial papules. The objective of the present article is to provide a detailed overview of the non-follicular cutaneous clinical manifestations of FFA and discuss their impact on the diagnosis and treatment of patients with this condition., (Copyright © 2024 Sociedade Brasileira de Dermatologia.

Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia of multifactorial etiology that presents on the vertex as patchy areas of hair loss, spreading centrifugally over the scalp. It most commonly affects women of African descent, but cases among other ethnicities have also been reported. CCCA typically starts with thinning and breaking of the hair as the first sign of presentation, which eventually progresses to hair loss over the central part of the scalp, spreading symmetrically outwards to involve a larger area. Currently, there is no definitive cure for the disease; however, multiple management options are available, which should aim to be tailored to the individual patient. Owing to its cosmetic outcomes, the quality of life (QoL) of patients with central centrifugal cicatricial alopecia is also disturbed, as patients may face psychological and social stress due to their permanent hair loss. This article focuses on various aspects of the pathogenesis, clinical trials, quality of life, barriers faced by patients, and treatment of central centrifugal cicatricial alopecia., (© 2024.

Lipedematous scalp (LS) and lipedematous alopecia (LA) are uncommon conditions with an unclear cause. Over the past century, about 115 cases have been documented in the literature. It is unknown if these disorders are indeed so uncommon or if cases that accept the illness as a structural alteration or are asymptomatic make the disease appear more uncommon than it is. Despite the fact that the majority of cases are seen in young and middle-aged people, the cases involving congenital, elderly, and children have also been reported. In the reported cases, female gender was observed to be dominant. The most significant clinical characteristics include felty swelling of the scalp in both disorders, diffusely or locally enlarged subcutaneous tissue with a swampy, spongy feel, and varied degrees of alopecia in LA. There is still much to learn about the pathogenetic mechanisms and therapeutic approaches for LA and LS. In this article, I review the general clinical characteristics, supposed pathogenetic mechanisms, histopathologic characteristics, diagnostic procedures, and management strategies for LS and LA., (© 2024.

Purpose: The dosimetry of scalp dose was prospectively studied and correlated with alopecia following conventional cranial irradiation in primary brain tumors patients., Materials and Methods: Patients with primary brain tumors who required conventional radiotherapy were enrolled. A hairline marker was applied to the patient's scalp to identify the entire scalp region. The maximal dose to 2% volume of interest (D2) for the entire scalp region were obtained. The radiation dosages at the localized hair-loss areas were evaluated during the final week of RT (transient alopecia) and six months after completing RT (permanent alopecia). Kruskal-Wallis tests were used to compare the dosimetric parameter values with statistical significance set as p < 0.05., Results: Forty-eight patients were included in the analysis. The prescribed radiation doses ranged from 50.4 to 60.0 Gy. Thirty-two patients experienced alopecia (27 transient and 5 permanent). The median D2 values adjusted for the entire scalp were higher in the alopecia group (38.40 Gy for transient alopecia and 47.84 Gy for permanent alopecia vs 11.90 Gy for no alopecia, p < 0.001). The D2 value was determined as a predictive parameter for alopecia. The threshold values for transient and permanent alopecia over the entire scalp were 22.15 Gy and 36.81 Gy, respectively. At the localized hair-loss areas, the D2 values for transient and permanent alopecia were higher at 44.82 Gy and 50.00 Gy, respectively. The radiation intensity at the localized hair-loss areas was also related to the severity of alopecia, with D2 values of 35.14 Gy and 46.39 Gy for clinically assigned grade 1 and grade 2 transient alopecia, respectively, with the D2 value being even higher for permanent alopecia., Conclusions: The D2 parameter value could be used to predict the type and severity of alopecia., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Jia-Mahasap et al.

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).

More than 80 million people in the United States are affected by hair loss, also known as alopecia. Nonscarring alopecias are categorized as diffuse, patterned, or focal. Diffuse alopecias include telogen and anagen effluvium, are usually self-limited, and depend on stopping the underlying cause (e.g., stress). Patterned hair loss, specifically androgenetic alopecia, is the most common form of alopecia; it is typically genetic, and first-line treatment is minoxidil. Oral finasteride is another treatment available for male patients. Focal hair loss includes alopecia areata, which is typically self-limited and treated with intralesional corticosteroid or oral immunosuppressant therapy; tinea capitis, which is treated with oral antifungals; and traction alopecia, which is treated by decreasing tension on the hair. Hair loss can be caused by several systemic diseases. A comprehensive history and physical examination, with targeted laboratory testing, may elucidate malnutrition, autoimmune diseases, and endocrine disease. Patients with moderate to severe hair loss are more likely to have accompanying anxiety, depression, and lower work productivity and quality-of-life scores. Educating patients about expected hair changes, treatment options, and realistic outcomes can help patients feel that they are being listened to and that their hair loss is being taken seriously.

Objectives: To evaluate the possible association between androgenic alopecia (AGA) and lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH)., Methods: A total of 148 patients aged over 45 with LUTS secondary to BPH were prospectively enrolled in this study. According to the Norwood-Hamilton classification, the patients were divided into two groups: AGA (n = 69) and non-AGA (n = 79). In addition, the cases of AGA were categorized as vertex (n = 39) and frontal baldness (n = 30). The International Prostate Symptom Score (IPSS), uroflowmetry parameters, prostate volume, serum total testosterone (TT), and free and total prostate-specific antigen concentrations of all patients were assessed and compared between the groups. Correlations between the AGA grade and other variables were also investigated., Results: The serum TT level (354 ± 97.1 vs. 308.6 ± 73.1 ng/dL, p = 0.01), total IPSS (16.1 ± 8.1 vs. 13.4 ± 7.7, p = 0.04), IPSS storage subscore (IPSS-S) (7.1 ± 3.5 vs. 5.8 ± 3.6, p = 0.03), and number of nocturia episodes (2.5 ± 1.4 vs. 1.8 ± 1.4, p < 0.01) were significantly higher in the AGA group than in the non-AGA group. There were no significant differences in any of the parameters between the patients with vertex and frontal baldness. The AGA grade showed a significant positive correlation with the TT level (r = 0.407, p = 0.003), IPSS-S (r = 0.164, p = 0.04), and number of nocturia episodes (r = 0.203, p = 0.015)., Conclusions: This study demonstrated that among patients with LUTS, those with AGA had worse symptoms and higher TT levels compared with those without AGA of similar age. Furthermore, the AGA grade was positively correlated with the TT level and storage symptoms., (© 2024 John Wiley & Sons Australia, Ltd.)

Background and Objective: Breast cancer is the leading cause of cancer among women, with over 2.3 million women being diagnosed in 2022. In addition to the emotional and physical toll that comes with a new cancer diagnosis, treatments such as chemotherapies, endocrine therapies, and radiation therapies may cause undesirable side effects. Side effects from cancer treatments can be detrimental to the quality of life of patients and their support systems. This narrative review consolidates current research on the impacts of alopecia on breast cancer survivors and provides a comprehensive overview of the various preventative options and treatments available., Methods: Current literature on alopecia and breast cancer was searched using PubMed and Google Scholar. The search strategy utilized a combination of keywords related to breast cancer, alopecia, body image, and alopecia prevention and treatment. Retrievable and English articles from January 2000 to April 2024 were included in the review., Key Content and Findings: Women with breast cancer cited alopecia, or hair loss, as the third-most undesirable side effect from chemotherapy, only trailing behind nausea and vomiting. Other studies have further supported this notion, expressing that alopecia negatively impacts patients' body image, social functioning, and sense of self. Further research has indicated that alopecia could hinder individuals from accessing essential cancer therapies. Breast cancer patients use a variety of coping strategies for cancer treatment-induced alopecia, including preventive measures, treatments to accelerate hair regrowth, camouflaging tools, and psychosocial supports., Conclusions: Alopecia, as a result of cancer treatment, has many significant and distressing effects on breast cancer patients. Customized interventions may help breast cancer patients feel more comfortable about themselves, after experiencing chemotherapy-induced alopecia. These findings indicate the need for further research on preventative options and treatments for cancer treatment-induced alopecia.

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.

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.)

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 (D mean ), and volume of the scalp receiving 30 Gy (V 30 ) and 40 Gy (V 40 ) 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 D mean and D max 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.)

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.

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.

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.)

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.

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.

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.

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.

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.

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.)

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).)

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.

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.

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.

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.

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.

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.)

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.

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.)
