Background: Alopecia areata is an autoimmune disorder affecting the hair-bearing sites of the body. Trichoscopy has recently been practiced in the diagnosis of alopecia areata. Aim: To elicit trichoscopy patterns in alopecia areata and to find out any correlation of trichoscopic findings with disease severity. Methods: Trichoscopy was done on clinically diagnosed cases of alopecia areata and on age and sex-matched controls without hair disorders by using a DL1 dermoscope (magnification: ×10). Observed dermoscopic findings were analyzed to find the correlation with disease severity. Results: In total, 87 cases and 60 controls were included in the study with the mean age for cases being 25.47 ± 14.07 years. There was male predominance of cases (51; 58.62%). Alopecia in multiple patches was the most common type (42; 48.27%), and scalp was the most common site of involvement (79; 90.8%). Yellow dots (YD), black dots (BD), broken hairs (BH), circle hair (CH), and tapering hairs (TH) or exclamation hair (EH) were found to be statistically significant findings in alopecia areata as compared to controls. Circle hair was significantly associated with total severity of alopecia areata (P = 0.041). Yellow dots had a positive correlation with the number of episodes of alopecia areata (Spearman's rho = 0.273, P = 0.0106) and mean severity of alopecia tool (SALT) score (P = 0.0130). No significant association was noted between trichoscopic findings and disease activity, family history, disease associations, or nail involvement. Conclusion: A constellation of trichoscopic findings helps in establishing the diagnosis of alopecia areata obviating the need for biopsy.

Full textAbstract:
Background. Diagnosis of patchy hair loss in pediatric patients is often a matter of considerable debate among dermatologists. Trichoscopy is a rapid and noninvasive tool to detect more details of patchy hair loss. Like clinical dermatology, trichoscopy works parallel to the skin surface and perpendicular to the histological plane; like the histopathology, it thus allows the viewing of structures not discovered by the naked eye.Objective. Aiming to compare the different trichoscopic features of tinea capitis and alopecia areata in pediatric patients.Patients and Methods. This study included 40 patients, 20 patients with tinea capitis and 20 patients with alopecia areata. They were exposed toclinical examination, laboratory investigations (10% KOH and fungal culture), and trichoscope examination.Results. Our obtained results reported that, in tinea capitis patients, comma shaped hairs, corkscrew hairs, and zigzag shaped hairs are the diagnostic trichoscopic features of tinea capitis. While in alopecia areata patients, the most trichoscopic specific features were yellow dots, exclamation mark, and short vellus hairs.Conclusion. Trichoscopy can be used as a noninvasive tool for rapid diagnosis of tinea capitis and alopecia areata in pediatric patients.

Objectives: Alopecia areata (AA) is a common autoimmune hair disorder with variable disease activity and severity. Conventionally, hair pull test (HPT) and off late trichoscopy are used to diagnose and monitor disease course in AA. The aim of the study was to evaluate the use of trichoscope in monitoring the disease activity, severity, and therapeutic response in AA. Material and Methods: This was a hospital-based and longitudinal study. Consecutive patients with AA between March 2018 and February 2019 were included in the study. Baseline clinical examination, HPT, and trichoscopy of patients was done at baseline and adequate treatment initiated. Monthly follow-up for next 3 months was done to study response to treatment. Results: Black dots (BDs) (100%) were commonest trichoscopic feature followed by yellow dots (YDs) (93.5%). BDs, broken hairs (BHs), and short vellus hairs (SVH) had significant correlation with disease activity while all trichoscopic markers significantly correlated with disease severity. With each follow-up, mean values for YDs, BDs, and BHs were declining, while SVH was increasing steadily. The abatement of trichoscopic activity markers preceded the disappearance of a positive HPT. Conclusion: The abatement of trichoscopic markers of disease activity in AA preceded a negative HPT, highlighting the role of trichoscopy as a useful tool in monitoring therapeutic response.

<strong>Background: </strong>Clinical diagnosis of hair and scalp disorders is not always straightforward. The standard methods used to diagnose hair loss disorders vary in sensitivity, reproducibility, and invasiveness. Trichoscopy holds great promise as a noninvasive tool for the evaluation of alopecia but it is greatly underutilized. <strong>Aims: </strong>To find the trichoscopic features in each type of non-cicatricial alopecia, to compare the trichoscopic characteristics of different types of non-cicatricial alopecia, and to identify features of diagnostic value. <strong>Methods: </strong>This cross-sectional study included 200 patients with non-cicatricial alopecia. After obtaining consent, a detailed history was taken and clinical examination was done. Hair and scalp were evaluated using a Dermlite DL3 dermoscope with 20 x magnification and optimal trichoscopic images were captured with an attached digital camera and findings were noted. <strong>Results: </strong>The most frequent type of non-scarring alopecia in the study sample was androgenetic alopecia (46%) followed by telogen effluvium(23%) and alopecia areata (22%). Various trichoscopic findings with diagnostic value identified in the study include hair shaft thickness heterogeneity, vellus hair, brown peripilar sign in androgenetic alopecia and female pattern hair loss and exclamation mark hair, black dots, comma hairs, broken hair in Alopecia areata. The absence of hair shaft heterogeneity and vellus hair are the important characteristics that help differentiate Telogen effluvium from Female Pattern hair loss. <strong>Conclusion: </strong>The trichoscopic findings with diagnostic value in different alopecia were identified. Trichoscopy helped to reach a definite diagnosis in patients in whom clinical diagnosis was doubtful and hence is a useful noninvasive tool in evaluating alopecia.

Full textAbstract:
Introduction. Focal alopecia in the parietal area is one of the types of hair loss that can be found in dermatological practice. Trichoscopy is a non-invasive and easily accessible diagnostic method widely used in scalp disorders.Aim. The aim of this study was to assess the usefulness of trichoscopy in the non-invasive diagnosis of focal hair loss in adult women.Material and Methods. The study included 40 adult women. The study group consisted of 30 patients including 10 patients with alopecia areata (AA), 10 patients with discoid lupus erythematosus (DLE) and 10 with classical form of lichen planopilaris (LPP). The control group consisted of 10 healthy volunteers. Four groups of structures observed in trichoscopic examination were evaluated: hair follicle openings, hair shafts, vessels, perifollicular and interfollicular skin surface. Results. Among patients with AA the most frequently observed trichoscopic structures were: yellow dots in 100% (10/10), broken hairs in 90% (9/10), hairs resembling exclamation marks in 90% (9/10). DLE patients most often presented white / white-pink structureless areas and prominent, interfollicular scaling in 100% (10/10) and 90% (9/10) of cases, respectively. On the other hand, in the group of patients with LPP, the most frequent findings were: fine perifollicular scaling in 100% (10/10) and linear, slightly branched vessels arranged concentrically around the follicular openings - both features observed also in 100% (10/10) of cases.Conclusion. Trichoscopy as a non-invasive diagnostic method may be helpful in differentiating non-scarring and scarring alopecia in the parietal area in women. Moreover, there are some trichoscopic features typical for AA, DLE and LPP, which allow for differentiation and facilitate the diagnosis of these entities.

Pendahuluan: COVID-19 merupakan suatu pandemi global yang menyebabkan morbiditas dan mortalitas yang belum pernah terjadi sebelumnya. Selain gejala pernapasan, manifestasi dermatologikus juga telah dilaporkan secara luas, dengan manifestasi dominan berupa kerontokan rambut. Ilustrasi kasus: Seorang laki-laki berusia 32 tahun mengalami kebotakan setempat pada area vertex kepala yang muncul 1 bulan setelah mengalami infeksi kedua SARS-CoV-2. Riwayat gangguan autoimun dan kebotakan disangkal. Pemeriksaan trikoskopi ditemukan gambaran yellow-dots, black-dots, broken-hairs, dan exclamation-mark hairs. Pasien diobati dengan minoxidil dan tretinoin topikal selama tiga bulan dengan respons yang sangat baik. Diskusi: Infeksi COVID-19 dan stress psikologis akibat infeksi COVID-19 dapat memicu alopesia areata (AA). Infeksi COVID-19 menginduksi aktivasi kaskade sitokin yang melibatkan interferon sehingga mengganggu hair follicle immune privilege (HFIP). Sementara itu, stress psikologis juga meningkatkan peradangan neurogenik dan beralih ke respons imun sel T-helper tipe 1 yang memengaruhi pertumbuhan rambut. Terdapat tiga laporan sebelumnya mengenai AA onset baru paska infeksi COVID-19 dan laporan kami adalah satu-satunya AA onset baru paska reinfeksi COVID-19. Kesimpulan: Laporan kami mengenai AA onset baru paska reinfeksi COVID-19 memberikan wawasan tentang kemungkinan hubungan antara infeksi COVID-19 dan AA. Timbulnya AA pada pasien COVID-19 merupakan gejala sisa/sekuele paska COVID-19 yang disebabkan oleh respon imun atau tekanan psikologis.

Background: Alopecia areata (AA) is an autoimmune disease that causes patchy hair loss. In children, AA can have a significant psychological impact. This study aims to identify the characteristics, clinical and trichoscopic features of AA pediatric patients at the dermatology clinic of Dr. M. Djamil General Hospital Padang. Methods: This cross-sectional analytical observational study involved pediatric patients (<18 years) with a diagnosis of AA who came to the dermatology clinic of Dr. M. Djamil General Hospital Padang between January 2020 to December 2023. Demographic data, disease history, clinical features, and trichoscopy examination results were collected and analyzed descriptively. Results: A total of 125 pediatric AA patients met the inclusion criteria. The majority of patients were female (62.4%) with a mean age of 10.5 years. The most common form of AA is patchy (80%), followed by alopecia totalis/universalis (12%) and ophiasis (8%). A history of atopy was found in 35.2% of patients. The most frequently found trichoscopic features were yellow dots (78.4%), black dots (64%), and broken hairs (56%). Conclusion: This study provides a comprehensive description of the characteristics, clinical and trichoscopic characteristics of AA pediatric patients at Dr. M. Djamil General Hospital Padang. These findings may provide a basis for the development of better management strategies for AA in children.

Full textAbstract:
Background Artificial intelligence (AI) has emerged in dermatology with some studies focusing on skin disorders such as skin cancer, atopic dermatitis, psoriasis, and onychomycosis. Alopecia areata (AA) is a dermatological disease whose prevalence is 0.7%-3% in the United States, and is characterized by oval areas of nonscarring hair loss of the scalp or body without evident clinical variables to predict its response to the treatment. Nonetheless, some studies suggest a predictive value of trichoscopic features in the evaluation of treatment responses. Assuming that black dots, broken hairs, exclamation marks, and tapered hairs are markers of negative predictive value of the treatment response, while yellow dots are markers of no response to treatment according to recent studies, the absence of these trichoscopic features could indicate favorable disease evolution without treatment or even predict its response. Nonetheless, no studies have reportedly evaluated the role of AI in AA on the basis of trichoscopic features. Objective This study aimed to develop an AI algorithm to predict, using trichoscopic images, those patients diagnosed with AA with a better disease evolution. Methods In total, 80 trichoscopic images were included and classified in those with or without features of negative prognosis. Using a data augmentation technique, they were multiplied to 179 images to train an AI algorithm, as previously carried out with dermoscopic images of skin tumors with a favorable response. Subsequently, 82 new images of AA were presented to the algorithm, and the algorithm classified these patients as responders and non-responders; this process was reviewed by an expert trichologist observer and presented a concordance higher than 90% with the algorithm identifying structures described previously. Evolution of the cases was followed up to truly determine their response to treatment and, therefore, to assess the predictive value of the algorithm. Results In total, 32 of 40 (80%) images of patients predicted as nonresponders scarcely showed response to the treatment, while 34 of 42 (81%) images of those predicted as responders showed a favorable response to the treatment. Conclusions The development of an AI algorithm or tool could be useful to predict AA evolution and its response to treatment. However, further research is needed, including larger sample images or trained algorithms, by using images previously classified in accordance with the disease evolution and not with trichoscopic features. Conflicts of Interest None declared.

Full textAbstract:
Alopecia areata (AA) is one of the most common hair loss disorders, with a prevalence of 0.1% - 0.2% of the general population. AA is regarded as a T-cell-mediated autoimmune condition characterized by non-scarring hair loss affecting only parts of the scalp, the entire scalp, or parts of the body. AA may manifest as a single episode or may have a relapsing course. Dermoscopy of the hair and scalp is known as trichoscopy. It is a useful method for diagnosing and monitoring hair and scalp disorders, as well as monitoring the effect of the applied treatment. The presence of exclamation mark hairs, black dots, triangular hairs, broken hairs, and pointed hairs in the alopecic patches indicates disease activity. One of the most common trichoscopic features of AA are the yellow dots - empty follicular openings filled with keratin and sebum. They predominate in long-standing, inactive diseases. Short vellus hairs are also common. The hair regrowth phase includes upright regrowing hairs and circle hairs. Diagnosis should be based on the coexistence of several trichoscopic findings rather than the presence of a single sign.
