[PMID: 38610726 PMCID: PMC11012765 DOI: 10.3390/jcm13071962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 03/21/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
Background: Androgenetic alopecia, the most common cause of non-scarring hair loss, is a consequence of the gradual miniaturization of the hair follicles. In the majority of male androgenetic alopecia cases, a patient's history and clinical evaluation may be sufficient to establish the diagnosis, while for women, they should be supplemented with trichoscopy. Methods: The PubMed and Scopus databases were used to collate published studies and to analyze the most typical trichoscopic findings in patients diagnosed with androgenetic alopecia. A total of 34 articles were retrieved after exclusion. Results: The most common features identified using trichoscopy included hair diameter variability (94.07% of patients), vellus hairs (66.45%) and the peripilar sign (43.27%). Others, such as the honeycomb pattern, yellow and white dots, were less relevant. Conclusions: We concluded that hair diameter variability, vellus hairs and the peripilar sign represented valuable indicators for the diagnosis of androgenetic alopecia.

Abstract
INTRODUCTION Severe acute respiratory virus syndrome coronavirus 2 (SARS-CoV-2) was responsible for coronavirus disease (COVID-19) pandemic. As patients recovered from COVID-19 infection, hair loss was increasingly observed as a distressing symptom. METHODS This was a cross-sectional study of patients with post COVID-19 hair loss between July to December 2021 at a tertiary care center. Detailed history, clinical examination, trichoscopy and biochemical tests were performed and recorded. COVID-19 disease severity was assessed based on duration of COVID-19 infection and place of management. RESULTS The study included 120 patients with a mean age of 39.6 years. The majority of the patients were females treated at home and had COVID-19 infection for >2 weeks. The mean visual analog scale (VAS) score for stress was 5.25. Vitamin D deficiency was present in 56.7% and low ferritin in 30% of cases. The mean time of onset of hair loss post COVID-19 was 49 days. Patients mainly presented with diffuse hair loss. Trichodynia was present in 15.8% of cases. The degree of hair loss was severe in 55.8% of the subjects. Positive hair pull test was seen in 65% of patients. Most common trichoscopic features included single hair follicles (81.7%) and vellus hair >10% (60%). CONCLUSIONS The mean time of onset of hair loss post COVID-19 infection was less than 2 months. Majority patients had diffuse pattern and severe degree of hair loss. Trichoscopy can aid in unmasking co-existing patterned hair loss in patients presenting clinically with diffuse hair loss.

Abstract
Hair and scalp disorders are of significant interest for physicians dealing with dark phototypes due to their prevalence and potential aesthetic impact resulting from a higher tendency for scarring. In order to facilitate their non-invasive diagnosis, several dermoscopic studies have been published, yet data are sparse and no systematic analysis of the literature has been performed so far. This systematic literature review summarizes published data on trichoscopy of hair and scalp diseases (trichoscopic findings, used setting, pathological correlation, and level of evidence of studies). A total of 60 papers addressing 19 different disorders (eight non-cicatricial alopecias, nine cicatricial alopecias, and two hair shaft disorders) were assessed, for a total of 2636 instances. They included one cross-sectional analysis, 20 case-control studies, 25 case-series, and 14 single case-reports, so the level of evidence was V and IV in 65% and 33% of cases, respectively, with only one study showing a level of evidence of III. Notably, although there is a considerable body of literature on trichoscopy of hair/scalp diseases, our review underlined that potentially significant variables (e.g., disease stage or hair texture) are often not taken into account in published analyses, with possible biases on trichoscopic patterns, especially when it comes to hair shaft changes. Further analyses considering all such issues are therefore needed.

Int J Trichology 2023; 15:144-148. [PMID: 38765725 PMCID: PMC11098145 DOI: 10.4103/ijt.ijt_31_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2022] [Revised: 06/20/2022] [Accepted: 06/22/2022] [Indexed: 05/22/2024] Open
Abstract
Introduction Androgenetic alopecia (AGA) is a progressive loss of terminal hairs in a specific pattern distribution related to androgen. The dermoscopy of hair and scalp, known as trichoscopy, is a noninvasive method for diagnosing alopecia and other hair and scalp disorders. Objective This study aims to report the correlation between the severity of males with AGA based on Hamilton-Norwood's scale with the clinical characteristics found in trichoscopy. Materials and Methods This study included 40 patients aged 25-58 years who visited the dermatology outpatient clinic in a tertiary health facility in Indonesia. Clinical diagnosis was determined through history taking, physical examination, and trichoscopy. Based on Hamilton-Norwood's criteria, patients were divided into two groups: early and late stage. Parameters examined in trichoscopy include yellow dots, white dots, peripilar sign, vellus hair, hair diameter diversity, single-hair follicles, and empty follicles. The Chi-square test and Fisher's exact test were used to analyze the statistical significance between the groups. Results All participants presented with hair diameter diversity, vellus hair, and empty follicles (100%). None of the study participants had yellow dots. White dots and single-hair follicles were seen in 32 (80%) and 30 cases (75%), respectively. In the late-stage group, these features were more prevalent. Peripilar sign was found in 25 participants (62.50%), and it was more common in the early-stage group. No significant association was found between disease severity and trichoscopy features. Conclusion The most common trichoscopy findings in particular order were hair diameter diversity, vellus hair, and empty follicles, followed by white dots, single-hair follicles, and peripilar signs. No significant association between alopecia severity and trichoscopy parameters was observed. Studies with a larger number of participants, including a control group, should be conducted to yield more significant results.

Abstract
Hyperthyroidism is known to cause thin, brittle hair, and premature graying. Hair shaft abnormalities in hyperthyroidism have not been described in the literature. A visible and microscopic change in the hair shaft due to cosmetic procedures and environmental factors is known as hair weathering. Herein, we report a case of hair weathering in an adult female with hyperthyroidism with unique dermoscopic features.

Abstract
BACKGROUND The incidence of alopecia areata (AA) has increased over the last few decades. Trichoscopy is a noninvasive procedure performed in dermatology clinics and is a helpful tool in determining the correct diagnosis of hair loss presentations. OBJECTIVE Through mapping the researches that have been done to represent the spectrum of trichoscopic findings in AA and to identify the most characteristic patterns. METHODS Thirty-nine studies were eligible for the quantitative analysis. Meta-analysis and subgroup analysis were performed. RESULTS Thirty-nine studies (29 cross-sectional, five retrospective, two descriptive, one case series, one observational, and one cohort) with a total of 3204 patients were included. About 66.7% of the studies were from Asia, 25.6% from Europe, and 7.7% from Africa. The most characteristic trichoscopic findings of AA were as follows; yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs. CONCLUSION There is no single pathognomonic diagnostic trichoscopic finding in AA rather than a constellation of characteristic findings. The five most characteristic trichoscopic findings in AA are: yellow dots, black dots, broken hairs, short vellus hairs, and tapering hairs. Yellow dots and short vellus hairs considered the most sensitive clues for AA, while black dots and tapering hairs are the most specific ones. Furthermore, trichoscopy is a useful tool that allows monitoring of response during the treatment of AA. Treatment responded cases will show an increase in short vellus hairs, but loss of tapering hairs, broken hairs, and black dots, while yellow dots are the least responsive to the treatment.

Abstract
INTRODUCTION Non-invasive diagnostic methods in clinical dermatology are widely used to reduce the need for invasive techniques, with great advantages in terms of cost and time. Dermoscopy is the reference test for the in vivo diagnosis of cutaneous lesions, and when it is performed on the scalp region it is named trichoscopy. Fluorescence advanced videodermoscopy (FAV) has been lately proposed as a new non-invasive method for the in vivo skin examination at high magnification, with cell-level resolution. So far, it has shown promising results for the assessment of melanocytic and vascular lesions and for the in vivo diagnosis of parasitosis. OBJECTIVES This observational study aims to perform, for the first time, a morphologic study of healthy scalp and scalp elementary lesions using FAV and to compare it with trichoscopy. METHODS We enrolled 90 healthy individuals for the evaluation of the scalp using FAV. Then, we recruited 53 patients with alopecia and collected images of the elementary lesions using FAV and trichoscopy. RESULTS Three hundred healthy scalp FAV images of different epidermal layers, papillary dermis, follicular ostia and healthy hair shafts were collected. Three hundred and eighty FAV and trichoscopic images of alopecic scalp elementary lesions were collected, showing that FAV provided a more detailed observation than trichoscopy, with higher magnification and cellular resolution. CONCLUSION Fluorescence advanced videodermoscopy may represent a new valid technique of support to trichoscopy, adding further information, increasing chances of diagnosis and decreasing the need of invasive procedures.

Abstract
Background: Androgenetic alopecia (AGA) is an androgen-related condition that develops in genetically predisposed individuals. The condition is characterized by the progressive loss of terminal hairs on the scalp in a characteristic distribution. Trichoscopy represents the dermoscopy imaging of the scalp and hair. Structures which may be visualized by trichoscopy include hair shafts, hair follicle openings, perifollicular epidermis and cutaneous microvessels. Objective: The aim of this prospective study was to identify the trichoscopic features of androgenetic alopecia. Methods: Hundred-four patients with AGA and 80 healthy subjects were enrolled in this study. Data on age, gender, personal and family history, clinical type and duration of disease were collected and analyzed. Control group consisted of 80 generally healthy subjects. Trichoscopic examination was performed using either videodermatoscope or handheld dermatoskope. Trichoscopy results were obtained in frontal, occipital and both temporal areas of the scalp, including number of yellow dots and vellus hairs, number of hairs in one pilosebaceous unit and percentage of follicular ostia with perifollicular hyperpigmentation. The data were statistically evaluated. Results: The number of yellow dots, pilosebaceous units with only one hair and with perifollicular hyperpigmentation was significantly increased in androgenetic alopecia (p<0.05). The percentage of thin hairs (<0.03 mm) in AGA was significantly higher than in healthy controls (p<0.05). Conclusion: Our study has shown the significances of trichoscopy of patients with AGA. Regular clinical and trichoscopical follow-ups are very important to monitor disease activity and treatment tolerance.
