Abstract
Lichen sclerosus (LS) is an uncommon, chronic, inflammatory mucocutaneous disorder found predominantly in females with unknown etiology. It presents as a white sclerotic plaque commonly located on the anogenital area. Extragenital LS is less prevalent, and LS affecting the oral mucosa is extremely rare, with only 39 biopsy-confirmed cases reported in the literature. Due to its several mimicking conditions, histological examination is usually required for a definitive diagnosis, particularly in patients with oral LS. Current evidence-based treatment recommendations for oral LS are unavailable; however, most cases tend to improve after treatment with topical or intralesional corticosteroids. We report a case of a 58-year-old female referred from the otolaryngology department for evaluating an asymptomatic whitish sclerotic plaque on the lower lip mucosa that had existed for 1 year. Following a punch biopsy, the patient was diagnosed with LS of labial mucosa. The condition improved after 2 months of treatment with topical and intralesional corticosteroids. The present case report raises awareness in recognizing oral LS and contributes to knowledge of this rare disorder.

Abstract
Alopecia areata is an autoimmune hair loss disease that is non-scarring and is characterized by chronic inflammation at the hair follicle level. Clinically, patients' presentation varies from patchy, circumscribed scalp involvement to total body and scalp hair loss. Current management is guided by the degree of scalp and body involvement, with topical and intralesional steroid injections as primarily first-line for mild cases and broad immunosuppressants as the mainstay for more severe cases. Until recently, the limited number of blinded, randomized, placebo-controlled clinical trials for this disease had made establishing an evidence-based treatment paradigm challenging. However, growing insights into the pathogenesis of alopecia areata through blood and tissue analysis of human lesions have identified several promising targets for therapy. T-helper (Th) 1/interferon skewing has traditionally been described as the driver of disease; however, recent investigations suggest activation of additional immune mediators, including the Th2 pathway, interleukin (IL)-9, IL-23, and IL-32, as contributors to alopecia areata pathogenesis. The landscape of alopecia areata treatment has the potential to be transformed, as several novel targeted drugs are currently undergoing clinical trials. Given the recent US FDA approval of baricitinib and ritlecitinib, Janus kinase (JAK) inhibitors are a promising drug class for treating severe alopecia areata cases. This article will review the efficacy, safety, and tolerability of current treatments for alopecia areata, and will provide an overview of the emerging therapies that are leading the revolution in the management of this challenging disease.

Abstract
Background Syphilitic alopecia (SA) and alopecia areata (AA) are two distinct conditions that frequently present diagnostic difficulties, especially when differentiating between them due to their similar clinical presentations. Trichoscopy may help in differential diagnosis, but a comparison between trichoscopic features of SA and AA is yet to be researched. Objective To compare trichoscopic features between SA and AA and determine their discriminative values. Methods Electronic medical records and trichoscopic images of patients diagnosed with SA or AA between January 2000 and February 2022 were retrieved. Trichoscopic features were statistically compared, and their discriminative values were demonstrated as sensitivity, specificity, predictive value, likelihood ratio, and area under the receiver operating characteristic curve (AUC). Results A total of 69 patients were included: 23 SA and 46 AA cases were matched with a 1:2 ratio. Black dots, broken hairs, pigtail hairs, exclamation mark hairs, tapered hairs, angulated hairs, and non-pigmented regrowing hairs were significantly more prevalent in AA than in SA (all P<0.05), whereas erythematous background was more prevalent in SA than in AA patients (P=0.008). Among the aforementioned trichoscopic features, exclamation mark hairs and non-pigmented regrowing hairs had a high positive likelihood ratio for AA (16.17 and 8.34, respectively); however, only exclamation mark hairs revealed high AUC (AUC=0.816). Conclusion Despite the presence of several similar trichoscopic features between SA and AA, trichoscopy can aid in distinguishing between the two diseases. Exclamation mark hairs are the only trichoscopic feature that can be used to differentiate patients with clinically suspicious SA from those with AA.

Abstract
Background Female pattern hair loss (FPHL) is the most common hair loss disorder in women that can be classified into three patterns, including Ludwig, Olsen, and Hamilton-Norwood subtypes. Information regarding the comparison of demographics, clinical characteristics, and associated comorbidities among subtypes of FPHL is scarce and contradictory. Objective To evaluate and compare the epidemiology, clinical manifestations, and comorbid conditions of FPHL subtypes and determine their associated factors. Methods This retrospective study included patients who were diagnosed with FPHL between January 2000 and November 2021. Participants were classified into three subtypes, namely Ludwig, Olsen, and Hamilton-Norwood, and were statistically compared. Variables significantly associated with each FPHL subtype were identified using multivariable multinomial logistic regression analysis. Results Among the 519 patients with FPHL, the Ludwig subtype was the most prevalent (51.1%), followed by the Olsen (32.9%) and Hamilton-Norwood (16%) subtypes. The Hamilton-Norwood subtype revealed significantly higher frequencies of early disease onset (61.4%), menstrual irregularity (22.9%), polycystic ovary syndrome (PCOS, 18.1%), and seborrhea (30.1%) but lower frequencies of overweight (24.1%) and type 2 diabetes mellitus (DM, 2.4%). Multivariable multinomial regression analysis demonstrated that the Hamilton-Norwood subtype was a predictor for early disease onset and PCOS compared to Ludwig (early onset: odds ratio (OR) = 2.14, 95% confidence interval (CI) = 1.39-4.22, P = 0.02; PCOS: OR = 2.02, 95% CI = 1.55-4.84, P = 0.03), and Olsen (early onset: OR = 1.89, 95% CI = 1.03-3.92, P = 0.04; PCOS: OR = 2.24, 95% CI = 1.89-5.31, P = 0.01). In contrast, the Hamilton-Norwood pattern was at decreased risk for type 2 DM compared to Ludwig (OR = 0.51, 95% CI = 0.03-0.82, P = 0.02), and Olsen (OR = 0.68, 95% CI = 0.04-0.79, P = 0.03). Conclusion The Ludwig pattern was found to be the most prevalent FPHL subtype among Thai patients. Moreover, the Hamilton-Norwood subtype was associated with early disease onset and PCOS, whereas the Ludwig and Olsen subtypes were associated with type 2 DM.

Abstract
BACKGROUND Alopecia areata (AA) is a chronic disease with an unpredictable disease course and severe psychological impact. OBJECTIVE To provide evidence- and consensus-based insights regarding the treatment of patients with AA in Korea. METHODS We searched for relevant studies on the topical and device-based treatment of AA in the literature from inception until May 2021. Evidence-based recommendations were also prepared. The evidence for each statement was graded and classified according to the strength of the recommendations. Hair experts from the Korean Hair Research Society (KHRS) voted on the statements, and an agreement of 75% or greater was considered as consensus. RESULTS Currently, there remains a scarcity of topical treatments, which is supported by robust evidence from a number of high-quality randomized controlled trials. Current evidence supports the efficacy of topical corticosteroids, corticosteroid intralesional injection, and contact immunotherapy in AA patients. Topical corticosteroids and contact immunotherapy are recommended for pediatric AA. A consensus was achieved in 6 out of 14 (42.8%), and 1 out of 5 (20.0%) statements pertaining to topical and device-based treatments in AA, respectively. The expert consensus was from a single country, and the study may not cover all the treatments used. CONCLUSION The present study provides up-to-date, evidence-based treatment guidelines for AA based on the consensus reached among experts after considering regional healthcare circumstances, adding diversity to the previous guidelines.

Abstract
Background Patients with psoriasis are more likely than matched controls in the general population to have advanced liver fibrosis; however, our understanding of these patients is limited. There is currently no systematic evaluation of the prevalence and risk factors of liver fibrosis in psoriasis patients. Objective To evaluate the prevalence of psoriasis patients who are at high or low risk for advanced liver fibrosis and determine the risk factors for developing liver fibrosis. Methods Electronic searches were conducted using the PubMed, Embase, Scopus, and Cochrane Library databases from the dates of their inception till May 2022, using the PubMed, Embase, Scopus, and Cochrane Library databases. Any observational study describing the prevalence and/or risk factors for liver fibrosis in patients with psoriasis was included. Results Patients with psoriasis at high risk for advanced liver fibrosis had a pooled prevalence of 9.66% [95% confidence interval (CI): 6.92-12.75%, I 2 = 76.34%], whereas patients at low risk for advanced liver fibrosis had a pooled prevalence of 77.79% (95% CI: 73.23-82.05%, I 2 = 85.72%). Studies that recruited methotrexate (MTX)-naïve patients found a lower prevalence of advanced liver fibrosis (4.44, 95% CI: 1.17-9.22%, I 2 = 59.34%) than those that recruited MTX-user cohorts (12.25, 95% CI: 6.02-20.08%, I 2 = 82.34%). Age, sex, BMI, PASI score, psoriasis duration, MTX cumulative dose, and the prevalence of obesity, MTX users, diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome were not identified as sources of heterogeneity by meta-regression analysis. The pooled odds ratios for age >50 years, BMI > 30, diabetes mellitus, hypertension, dyslipidemia, and metabolic syndrome were 2.20 (95% CI: 1.42-3.40, I 2 = 0%), 3.67 (95% CI: 2.37-5.68, I 2 = 48.8%), 6.23 (95% CI: 4.39-8.84, I 2 = 42.4%), 2.82 (95% CI: 1.68-4.74, I 2 = 0%), 3.08 (95% CI: 1.90-4.98, I 2 = 0%), and 5.98 (95% CI: 3.63-9.83, I 2 = 17%), respectively. Conclusion Approximately 10% of the population with psoriasis is at high risk for advanced liver fibrosis, while 78% are at low risk. Patients over the age of 50 with obesity, diabetes, hypertension, dyslipidemia, and/or metabolic syndrome have an increased risk of developing liver fibrosis, necessitating monitoring.

Abstract
Background Immune-mediated alopecias (IMAs), a group of hair disorders associated with immunological reactions, remain a therapeutic challenge since available treatments are generally unfavorable with potential side effects. Platelet-rich plasma (PRP) has been recently proposed as a treatment option based on several limited-quality studies; however, there is no systematic evaluation of PRP efficacy on IMAs in the literature. Objective To assess PRP's effects in treating IMAs using a systematic review. Methods Electronic searches were conducted using PubMed, Embase, Scopus, and Cochrane Library databases. A search strategy was designed to retrieve all studies exploring PRP in treating IMAs, including alopecia areata (AA) and primary cicatricial alopecias (PCAs). In addition, all randomized and non-randomized studies reporting subjective and/or objective outcomes of alopecia treatment with PRP were included. Results Thirty-two studies were included, comprising 621 patients with AA and 19 patients with PCAs. PRP had superior efficacy as monotherapy in five studies, comparable to intralesional corticosteroids in six studies in AA treatment. In addition, in the analysis of PCAs, including lymphocytic and neutrophilic subtypes, PRP was efficacious in alleviating disease progression in nine studies. Conclusion PRP is considered a promising treatment for AA and PCAs in patients who experienced unfavorable outcomes from conventional treatment. However, its clinical application remains to be standardized, and its recommendation as a treatment for IMAs could not be ascertained due to a lack of high-quality evidence.

Abstract
INTRODUCTION Alopecia areata (AA) is a non-scarring, hair loss disorder and a common autoimmune-mediated disease with an estimated lifetime risk of about 2%. To date, the treatment of AA is mainly based on suppression or stimulation of the immune response. Genomics and transcriptomics studies generated important insights into the underlying pathophysiology, enabled discovery of molecular disease signatures, which were used in some of the recent clinical trials to monitor drug response and substantiated the consideration of new therapeutic modalities for the treatment of AA such as abatacept, dupilumab, ustekinumab and Janus Kinase (JAK) inhibitors. AREAS COVERED In this review, genomics and transcriptomics studies in AA are discussed in detail with particular emphasis on their past and prospective translational impacts. Microbiome studies are also briefly introduced. EXPERT OPINION The generation of large datasets using the new high-throughput technologies has revolutionized medical research and AA has also benefited from the wave of omics studies. However, the limitations associated with JAK inhibitors and clinical heterogeneity in AA patients underscore the necessity for continuing omics research in AA for discovery of novel therapeutic modalities and development of clinical tools for precision medicine.

Abstract
Introduction Intramuscular corticosteroids (IMC) have gained popularity for the treatment of severe alopecia areata (AA) in recent years; however, evidence on their efficacy and safety is still limited. Objective To evaluate the efficacy, relapse rate, and tolerability of IMC in the treatment of AA, as well as factors associated with treatment outcomes. Methods Time-to-event analysis was performed on patients with severe, extensive, or rapidly progressive AA receiving IMC. The IMC regimen comprised triamcinolone acetonide 20–40 mg/mL injected every 4–6 weeks. The evaluated outcomes included initial (25% regrowth), significant (75% regrowth), and complete hair regrowth (100% regrowth). Relapse and adverse events were also noted. Factors associated with treatment outcomes and relapse were analyzed using the Cox proportional hazards model. Results A total of 101 patients were eligible for analysis. Significant hair regrowth was obtained in 80.2% of the patients (n = 81), in a median time of 3.4 months (95% confidence interval [CI] = 2.9–4.4). Complete hair regrowth was achieved in 48.5% of the subjects (n = 49), and relapse was observed in 47.5% (n = 48). Acneiform eruption was the most common adverse effect. Multivariable analysis revealed that nail involvement was a negative predictor of significant hair regrowth (adjusted hazard ratio [HR] = 0.04, 95% CI = 0.01–0.55; P = 0.015), whereas duration of AA longer than 6 months was associated with disease recurrence (adjusted HR = 4.02, 95% CI = 1.52–4.66; P = 0.005). Conclusion This study demonstrated the efficacy and safety of IMC in the treatment of severe or active AA; however, the relapse rate remained relatively high after discontinuation of the therapy. Nail involvement was a negative predictor of significant hair regrowth, while disease duration longer than 6 months predicted AA relapse.

Abstract
BACKGROUND Increased rates of autoimmune diseases (ADs) have been reported in association with alopecia areata (AA); however, the risk factors for coexisting ADs in AA patients have been poorly investigated. OBJECTIVE To evaluate the prevalence and factors associated with AD comorbidities in patients with AA. METHODS This case-control study included patients diagnosed with AA between January 2000 and March 2020. Individuals with AA, both with and without concomitant ADs, were statistically compared. Variables significantly associated with coexisting ADs were identified using univariate and multivariate logistic regression analyses. Multinomial logistic regression analysis was performed to identify the specific risk factors for each concomitant AD. RESULTS Among the 615 patients with AA, comorbid ADs were found in 76 (12.4%). Autoimmune thyroid disease (AITD) exhibited the highest frequency (n = 42, 6.8%), followed by vitiligo (n = 15, 2.4%), and systemic lupus erythematosus (SLE) (n = 12, 2.0%). Logistic regression analyses revealed that female sex (odds ratio [OR] = 2.45, 95% confidence interval [CI] = 1.24-4.82; P = 0.011), nail abnormalities (OR = 2.49, 95% CI = 1.14-5.46; P = 0.023), and atopic diseases (OR = 1.98, 95% CI = 1.09-2.43; P < 0.001) were significantly associated with coexisting ADs. Regarding each concomitant AD, nail abnormalities were an associated factor for AITD (OR = 4.65, 95% CI = 1.96-7.24; P = 0.01), whereas coexisting atopic diseases were demonstrated as a predictor of vitiligo (OR = 2.48, 95% CI = 1.43-4.58; P = 0.02). Female sex (OR = 1.61, 95% CI = 1.18-4.27; P = 0.04) and family history of AD (OR = 1.85, 95% CI = 1.26-4.19; P = 0.03) were predictors of SLE. CONCLUSION This study suggests that female AA patients with nail abnormalities and atopic diseases have increased rates of AD comorbidities. A thorough review of systems for associated factors can help physicians screen for concomitant ADs.

Abstract
Alopecia areata (AA) is a common chronic tissue-specific autoimmune disease, resulting in hair loss, that affects up to 2% of the general population. The exact pathobiology of AA has still remained elusive, while the common theory is the collapse of the immune privilege of the hair follicle caused by immunological mechanism. Multiple genetic and environment factors contribute to the pathogenesis of AA. There are several clinical treatments for AA, varying from one or multiple well-defined patches to more diffuse or total hair loss of the scalp (alopecia totalis) or hair loss of the entire body (alopecia universalis). The available treatments for AA, such as corticosteroids and other immunomodulators, minoxidil, and contact immunotherapy, are of limited efficacy with a high risk of adverse effects and high recurrence rates, especially for patients with severe AA. Recent insights into the pathogenesis of AA have led to the development of new treatment strategies, such as Janus kinase (JAK) inhibitors, biologics, and several small molecular agents. In addition, modern therapies for AA, including antihistamines, platelet-rich plasma (PRP) injection, and other novel therapies have been well explored. In this review, we discussed the recent advances in the pathogenesis, diagnosis, and treatment of AA.

Abstract
Alopecia areata (AA) is an autoimmune disease of the hair follicles. It is characterized by a well-defined non-scarring alopecic patch or patches that may extend to the entire scalp or lead to total body hair loss. Due to its unpredictable clinical course, AA causes substantial psychological harm. Despite the high prevalence of this disease and extensive research, its exact pathomechanism is unclear, and current treatments have a high relapse rate that has deemed AA incurable. Over the past few decades, researchers have investigated multiple potential factors that may help alleviate its pathogenesis and provide effective treatment. Given its complex immunopathogenesis, AA is considered an autoimmune disease with multiple factors. This review gathers current evidence that emphasizes molecular mechanisms, possible causative etiologies, and targeted immunotherapies for AA. Understanding its underlying mechanisms may shed light on new strategies to effectively manage AA in the future.

Abstract
Treatment of extensive or recalcitrant alopecia areata (AA) is a major clinical challenge. Even after thorough investigation of several medications, its treatment outcomes have remained unsatisfactory. While there is no US Food and Drug Administration-approved medication for AA yet, topical immunotherapy has been a well-documented treatment option. Dinitrochlorobenzene, squaric acid dibutylester, and diphenylcyclopropenone are three substances that have demonstrated efficacy in the treatment of extensive or recalcitrant AA. Despite being commonly used, the mechanism underlying topical immunotherapy is not well-elucidated and a wide range of clinical efficacies have been reported in the literature. The aim of this review was to summarize and update the pharmacology, mechanism of action, therapeutic efficacy, and tolerability of topical immunotherapy in the treatment of AA.

Abstract
BACKGROUND Alopecia areata (AA) usually manifests as patches of non-scarring hair loss due to immune dysregulation. Intradermal injection of steroids is considered a first-line treatment of patchy AA. PURPOSE To compare the efficacy and safety of two commonly used concentrations of intralesional triamcinolone acetonide (ILT) (5 mg/mL vs 10 mg/mL) in the treatment of patchy AA on the scalp. PATIENTS AND METHODS A retrospective comparative study that included 85 patients diagnosed with patchy AA on the scalp, who were treated with monthly injections of ILT. Patients were divided into Group 1 that received 5 mg/mL and Group 2 that received 10 mg/mL. The response rate (defined as the percentage of patients who achieved complete hair regrowth) and the side effects were compared between the two groups after completion of three treatment sessions, and recurrence was assessed after 1-3 years. RESULTS Demographic composition of the two groups was comparable. The difference in response rate and the side-effects between the two groups were not statistically significant. Complete hair regrowth was noted in 43.5% of patients in Group 1 and 53.8% of those in Group 2 (P=0.340). About 17% and 25% of patients in Group 1 and Group 2, respectively, developed minor local side-effects (P=0.354), and almost 45% of patients from both groups had recurrence after 1-3 years. Disease duration exceeding 6 months correlated with poor treatment response. CONCLUSION Intralesional injection of triamcinolone acetonide 5 mg/mL is equally effective and safe compared to 10 mg/mL in the treatment of patchy alopecia areata.

Abstract
Intralesional steroid injection is a treatment method frequently used to resolve a large number of orthopedic, rheumatological, dermatological, and neurological disorders. Although this treatment is very effective, it is not without possible side effects, both systemic and local, among which we can mention pain, bleeding, ulceration, atrophy, pigmentary changes, calcification, secondary infections, formation of granulomas, allergic reactions and, in very rare cases, the development of linear atrophy, and hypopigmentation. Here, we present a case of frontal linear skin atrophy after intralesional steroid injection for the treatment of alopecia areata (AA) in a 29 year-old patient, successfully treated with a hyaluronic acid filler.

Abstract
BACKGROUND The hairline is an essential component of the human face. Disfigurement of the hairline may cause physical and psychological problems. Standard guidelines do not exist for female hairline designs, average values of infratemporal portion, hairline classifications, and preferences. AIMS We aimed to study hairline characteristics in Thai females and further compare the values with previous studies in different populations. Furthermore, we aimed to introduce a comprehensive hairline classification system that allowed an easy and detailed phenotypic characterization of female hairline. PATIENTS/METHODS Healthy Thai females aged over 18 years were included in the study. Collection of demographic data, infratemporal measurements, and standard photography was performed. All collected data were analyzed to determine the standard values of each hairline dimension for comparison to previous studies. RESULTS Two hundred and twenty-nine females, with a mean age of 32.4 ± 8.6 years, participated in this study. The mean mid-frontal line was 6.45 ± 0.89 cm, which was not correlated with age. Lateral mounds, widow's peaks, and cowlicks were observed in 42.35%, 24.45%, and 1.74% participants, respectively. Our study revealed five patterns of the frontal hairline and four patterns of the temporal hairline. The mid-frontal line in Asian females trended longer than that in Caucasians, without statistical significance. CONCLUSIONS Measurements of the infratemporal portions in Thai females revealed no change with age, and the mid-frontal line showed no statistically significant differences between Korean and Turkish participants. The hairline classification system introduced in our study was comprehensive and would be easily applicable in clinical practice. Female hairline dimensions and patterns reported in our study could provide reference values for hairline design in hairline restoration surgery as well as assist in accurate diagnosis of hair disorders.
