Abstract The Anais Brasileiros de Dermatologia, published since 1925, is the most influential dermatological journal in Latin America, indexed in the main international bibliographic databases, and occupies the 50th position among the 70 dermatological journals indexed in the Journal of Citations Reports, in 2022. In this article, the authors present a critical analysis of its trajectory in the last decade and compare its main bibliometric indices with Brazilian medical and international dermatological journals. The journal showed consistent growth in different bibliometric indices, which indicates a successful editorial policy and greater visibility in the international scientific community, attracting foreign authors. The increases in citations received (4.1 ×) and in the Article Influence Score (2.9×) were more prominent than those of the main Brazilian medical and international dermatological journals. The success of Anais Brasileiros de Dermatologia in the international scientific scenario depends on an assertive editorial policy, on promptly publication of high-quality articles, and on institutional stimulus to encourage clinical research in dermatology.

Abstract A plethora of prolonged COVID-19 symptoms, or late manifestations has been reported after acute disease and labeled “post-COVID”. The aim of this study was to identify the prevalence of and risk factors for post-COVID up to 12 weeks after the onset of acute COVID-19. An electronic survey was conducted to evaluate post-COVID-19 symptoms, disease severity, demographics, and pre-existing diseases. The participants were recruited through 88,648 SMS messages, and post on social media. The associations between variables were explored through multivariate models. From 6,958 respondents with confirmed COVID-19, 753 (10.8%) required hospitalization, and 5,791 (83.2%) exhibited at least one post-COVID manifestation. Hair loss (49.4%), memory loss (40.7%), low attention (37.0%), fatigue (34.2%), anxiety (31.2%), and headache (29.6%) were the most reported post-COVID manifestations. Female sex, myalgia, anosmia, and severe disease were associated with most post-COVID manifestations. Pre-existing depression was associated with the development of neuropsychiatric manifestations. Post-COVID manifestations were identified in most patients following COVID-19 infection, placing a supplementary burden on the healthcare system. Hair loss, fatigue, and neuropsychiatric symptoms were the most prevalent post-COVID manifestations. Female sex, myalgia, anosmia, and more severe disease are risk factors for multiple post-COVID manifestations.

Abstract This publication is an update of the “Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology” published in 2019, considering the novel, targeted-oriented systemic therapies for atopic dermatitis. The initial recommendations of the current consensus for systemic treatment of patients with atopic dermatitis were based on a recent review of scientific published data and a consensus was reached after voting. The Brazilian Society of Dermatology invited 31 experts from all regions of Brazil and 2 international experts on atopic dermatitis who fully contributed to the process. The methods included an e-Delphi study to avoid bias, a literature search and a final consensus meeting. The authors added novel approved drugs in Brazil and the indication for phototherapy and systemic therapy for AD. The therapeutical response to systemic treatment is hereby reported in a suitable form for clinical practice and is also part of this updated manuscript.

Abstract The JAK-STAT signaling pathway mediates important cellular processes such as immune response, carcinogenesis, cell differentiation, division and death. Therefore, drugs that interfere with different JAK-STAT signaling patterns have potential indications for various medical conditions. The main dermatological targets of JAK-STAT pathway inhibitors are inflammatory or autoimmune diseases such as psoriasis, vitiligo, atopic dermatitis and alopecia areata; however, several dermatoses are under investigation to expand this list of indications. As JAK-STAT pathway inhibitors should gradually occupy a relevant space in dermatological prescriptions, this review presents the main available drugs, their immunological effects, and their pharmacological characteristics, related to clinical efficacy and safety, aiming to validate the best dermatological practice. JAKSTAT JAK STAT response carcinogenesis differentiation death Therefore conditions psoriasis vitiligo areata however prescriptions effects characteristics safety practice

Abstract Background: Chromoblastomycosis is a skin infection caused by dematiaceous fungi that take the form of muriform cells in the tissue. It mainly manifests as verrucous plaques on the lower limbs of rural workers in tropical countries. Objectives: The primary objective of this review is to evaluate the accuracy of diagnostic methods for the identification of chromoblastomycosis, considering the histopathological examination as the reference test. Methods: MEDLINE, LILACS and Scielo databases were consulted using the terms ‟chromoblastomycosis” AND ‟diagnosis”. The eligibility criteria were: studies that evaluated the accuracy of tests for the diagnosis of chromoblastomycosis. Eleven studies were selected. Statistical analysis included the calculation of sensitivity and specificity of the diagnostic methods. Results: Considering the histopathological examination as the reference test, the culture showed a sensitivity (S) of 37.5% - 90.9% and a specificity (Sp) of 100%; while direct mycological examination showed S = 50% - 91.6% and Sp of 100% . Considering the culture as the reference test, the serology (precipitation techniques) showed S of 36% - 99%; and Sp of 80% - 100%; while the intradermal test showed S of 83.3% - 100% and Sp of 99.4% - 100%. Study limitations: The small number of studies and very discrepant sensitivity results among them do not allow the calculation of summary measures through a meta-analysis. Conclusions: Direct mycological examination, culture, intradermal test and serology show sensitivity and specificity values for the diagnosis of chromoblastomycosis with no significant difference between the studies.

Abstract Background: The Anais Brasileiros de Dermatologia (Anais Brasileiros de Dermatologia) is the official journal of the Brazilian Society of Dermatology, which has been published since 1925, with free, bilingual access. There are several bibliometric indicators that estimate aspects of a journal’s scientific influence. Its analysis, based especially on the evolutionary trend, allows identifying the journal’s strengths and weaknesses, in addition to guiding editorial policies. Objectives: To evaluate the trends of the main bibliometric indicators of Anais Brasileiros de Dermatologia, in the decade of 2010–2019. Methods: Methodological study that proposed the analysis of bibliometric indicators published by Journal Citation Reports, SCImago, and Scopus, for the journal Anais Brasileiros de Dermatologia, from 2010 to 2019. The following aspects were evaluated: Impact factor, Immediacy index, SJR (SCImago), in addition to the number of citations, citable items, Cite Score, percentage of external citations, percentage of cited articles, percentage of citable articles, and the article influence score. Results: There was an increase in the main bibliometric indicators in the last decade: impact factor (0.337 to 1.121), immediacy index (0.054 to 0.204),Eigenfactor (0.00025 to 0.00394), SJR (0.176 to 0.453). The percentage of external citations (48.4% to 94.1%) and cited articles (24.7% to 51.4%) also increased. The increase in the impact factors of Anais Brasileiros de Dermatologia in the period was more significant than that of the dermatology journals (1,667 to 2,118) and the Brazilian journals (1,247 to 1,408), indexed in the Journal Citation Reports. Study limitations: Failure in the classification and registration of the databases. Conclusions: There has been a consistent increase in the scientific influence of Anais Brasileiros de Dermatologia in the last decade.

Abstract Background: Isotretinoin is a synthetic retinoid, derived from vitamin A, with multiple mechanisms of action and highly effective in the treatment of acne, despite common adverse events, manageable and dose-dependent. Dose-independent teratogenicity is the most serious. Therefore, off-label prescriptions require strict criteria. Objective: To communicate the experience and recommendation of Brazilian dermatologists on oral use of the drug in dermatology. Methods: Eight experts from five universities were appointed by the Brazilian Society of Dermatology to develop a consensus on indications for this drug. Through the adapted DELPHI methodology, relevant elements were listed and an extensive analysis of the literature was carried out. The consensus was defined with the approval of at least 70% of the experts. Results: With 100% approval from the authors, there was no doubt about the efficacy of oral isotretinoin in the treatment of acne, including as an adjunct in the correction of scars. Common and manageable common adverse events are mucocutaneous in nature. Others, such as growth retardation, abnormal healing, depression, and inflammatory bowel disease have been thoroughly investigated, and there is no evidence of a causal association; they are rare, individual, and should not contraindicate the use of the drug. Regarding unapproved indications, it may represent an option in cases of refractory rosacea, severe seborrheic dermatitis, stabilization of field cancerization with advanced photoaging and, although incipient, frontal fibrosing alopecia. For keratinization disorders, acitretin performs better. In the opinion of the authors, indications for purely esthetic purposes or oil control are not recommended, particularly for women of childbearing age. Conclusions: Approved and non-approved indications, efficacy and adverse effects of oral isotretinoin in dermatology were presented and critically evaluated.

Abstract Syphilis is an infectious disease that has afflicted mankind for centuries, but a recent increase in worldwide incidence has been evidenced. The authors describe a patient with typical lesions of secondary syphilis and moth-eaten alopecia, whose dermoscopic examination demonstrated empty hair follicles, vellus hair, follicular hyperkeratosis, peripheral black dots, dilated and tortuous vessels, reddish brown background, and hypopigmentation of the hair shafts. Furthermore, this case presented an erythematous background more evident than previously described cases.

A 6 year-old patient began to experience localized hairloss in the right temporal region three years ago. During the first appointment, diagnoses of alopecia areata and congenital triangular alopecia were made. After one year, there was no change. Upon dermatological examination, non-scarring alopecia was noted in the right temporal region, revealing extremely fine and fair hair follicles. A dermoscopy revealed only thin vellus-type hairs. Congenital triangular alopecia is a condition commonly confused with alopecia areata and is thus underdiagnosed. However, well-established clinical parameters and dermoscopic criteria can be used to distinguish skin diseases that affect hair and define the diagnosis.

O granuloma facial é doença cutânea rara e benigna, de etiologia desconhecida, caracterizado por vasculite leucocitoclástica crônica. Caracteriza-se por lesões cutâneas predominantemente faciais, tem curso crônico e lentamente progressivo. O diagnóstico é baseado na clínica, histopatologia e, mais recentemente, na dermatoscopia. Relatamos o quadro de um paciente masculino, 40 anos de idade, com lesão sarcoídea na face malar, cujo exame histopatológico revelou infiltrado inflamatório misto com presença de zona de Grenz. A dermatoscopia revelou um fundo rosado com estrias brancas. O diagnóstico definitivo é feito pela avaliação histopatológica, sendo que a dermatoscopia pode ser útil. É conhecida por ser resistente à terapêutica, sendo propostas medicações orais, intralesionais e procedimentos cirúrgicos.

The granuloma faciale is a rare and benign skin disease of unknown etiology, characterized by chronic leukocitoclastic vasculitis. It is characterized by skin lesions predominantly facial whose course is chronic and slowly progressive. The diagnosis is based on clinical features, histopathology and, more recently, in dermoscopy. We describe the case of a male patient, 40 years old, with a sarcoid lesion on the malar site, whose histopathological examination revealed a mixed inflammatory infiltrate with presence of Grenz zone. Dermoscopy revealed a pink background with white striations. The definitive diagnosis is made by histopathologic evaluation, and dermatoscopy can be helpful. It is known to be resistant to therapy, oral medications, intralesional and surgical procedures are options.

A queratose actínica é uma causa comum de consultas dermatológicas e apresenta forte associação com o carcinoma espinocelular. Muitas substâncias são utilizadas para seu tratamento e prevenção, assim como os retinoides. Entretanto, muitos estudos sobre retinoides salientam seu uso no tratamento e prevenção de cânceres de pele não melanoma. Neste artigo, nós revisamos estudos que avaliam o uso dos retinoides sistêmicos e tópicos para pacientes imunocompetentes e imunossuprimidos com queratoses actínicas, como desfechos primários e secundários. A maioria destes estudos mostra redução na contagem das queratoses actínicas após o tratamento com retinóides. Além disso, ajustes no delineamento dos estudos deveriam ser feitos quanto à falta de padronização da dose, ausência de grupos controle, número pequeno de pacientes e tempo curto de seguimento. Ensaios clínicos cegos, randomizados e controlados com tamanho amostral adequado tendo como alvo específico as queratoses actínicas são necessários para esclarecer o real benefício dos retinoides tópicos e/ou orais. A comparação da eficácia e segurança entre os retinoides orais e tópicos na prevenção e tratamento dos cânceres de pele não melanoma e queratoses actínicas é um pré-requisito essencial para o estabelecimento de novas estratégias para o controle destas condições.

Actinic keratosis is a common cause of dermatological consultations and it presents a strong association with squamous cell carcinoma. Many substances are used for treatment and prevention, such as retinoids. Nevertheless, many studies on retinoids emphasize their application in treating and preventing non melanoma skin cancers. In this article, we reviewed studies about systemic and topical retinoids used with immunocompetent patients and organ transplant recipients with actinic keratosis, as primary or secondary outcomes. The majority of these papers pointed to a reduction in actinic keratosis count after treatment with retinoids. However, studies need to be better-defined in order to address the lack of a standardized dose, the absence of control groups, the low number of patients and short follow-up periods. Blind, randomized and controlled clinical trials with adequate sample sizes, specifically focused on actinic keratosis, are needed to clarify the real benefit of topical and/or oral retinoids. Comparison of efficacy and safety between oral and topical retinoids in the prevention and treatment of non-melanoma skin cancers and actinic keratosis is an essential pre requisite to establish new strategies to control these conditions.

FUNDAMENTOS: É bastante divulgado, sem a fundamentação científica necessária, que a infecção por molusco contagioso tende a ser mais frequente e de maior intensidade nos pacientes acometidos por dermatite atópica. Tal fato motivou a realização deste trabalho. OBJETIVOS: Avaliar a prevalência de associação de dermatite atópica e molusco contagioso; avaliar se, nos pacientes com dermatite atópica, a infecção por molusco contagioso é mais recorrente e/ou disseminada e se a ocorrência de eczema perimolusco, prurido e/ou infecção é mais prevalente que nos pacientes sem dermatite atópica. MÉTODOS: Avaliaram-se 284 crianças de ambos os sexos, com diagnóstico de molusco contagioso e/ ou dermatite atópica. RESULTADOS: Apenas 13,4% dos pacientes apresentavam ambas as doenças. O número de áreas anatômicas afetadas por molusco contagioso, a ocorrência de eczema perimolusco e prurido foram maiores nos pacientes com dermatite atópica associada. Não houve diferença significativa de frequência de infecção secundária associada às lesões de molusco contagioso nos pacientes com e sem dermatite atópica. CONCLUSÃO: A prevalência da ocorrência de dermatite atópica e molusco contagioso associados foi baixa. Não houve diferença significativa na recorrência da infecção por molusco contagioso e na quantidade de lesões nos pacientes com e sem dermatite atópica. O número de áreas anatômicas afetadas por lesões de molusco contagioso, a presença de eczema perimolusco e de prurido foram maiores nos pacientes com dermatite atópica. Não houve diferença significativa na ocorrência de infecção bacteriana secundária nos grupos com e sem dermatite atópica

BACKGROUND: Although no scientific evidence has yet been published, it is widely understood that molluscum contagiosum tends to be more common and more intense in patients with atopic dermatitis. This lack of evidence led to the development of the present study. OBJECTIVES: To evaluate the prevalence of the association between atopic dermatitis and molluscum contagiosum; to evaluate whether molluscum contagiosum is more likely to be recurrent and/or disseminated in patients with atopic dermatitis and whether the occurrence of eczema surrounding the molluscum contagiosum lesions, pruritus and/or infection is more prevalent in these patients compared to patients without atopic dermatitis. METHODS: A total of 284 children of both sexes with a diagnosis of molluscum contagiosum and/or atopic dermatitis were evaluated. RESULTS: Only 13.4% of the patients had both conditions. The number of anatomical areas affected by molluscum contagiosum and the occurrence of surrounding eczema and pruritus was greater in the patients who also had atopic dermatitis. There was no statistically significant difference in the frequency of secondary infection associated with the molluscum contagiosum lesions between the patients who had atopic dermatitis and those who did not. CONCLUSION: The prevalence of atopic dermatitis associated with molluscum contagiosum was low. There was no statistically significant difference in the recurrence rates associated with molluscum contagiosum or in the number of lesions between the patients who had atopic dermatitis and those who did not. The number of anatomical areas affected by the molluscum contagiosum lesions and the presence of surrounding eczema and pruritus were higher in the patients with atopic dermatitis. There was no statistically significant difference in the occurrence of secondary bacterial infection between the groups with and without atopic dermatitis

FUNDAMENTOS: Embora de fácil diagnóstico, o molusco contagioso pode apresentar-se como lesões inflamadas, únicas ou pequenas de difícil diagnóstico. OBJETIVO: Descrever características dermatoscópicas do molusco contagioso e comparar achados do exame clínico e dermatoscópico. MÉTODOS: Avaliou-se clínica e dermatoscopicamente lesões confirmadas pela histopatologia em 57 pacientes. RESULTADOS: Nos exames clínico e dermatoscópico de 211 lesões, foram visualizados orifícios em 50,24% e 96,68% das lesões e vasos em 6,16% e 89,10% delas, respectivamente. Os padrões vasculares encontrados em 188 lesões que apresentaram vasos à dermatoscopia foram coroa (72,34%), radial (54,25%) e puntiforme (20,21%). Metade das 188 lesões apresentou padrão vascular combinado, sendo o padrão em flor (novo padrão vascular) responsável por 19,68%. Foram identificados mais orifícios e vasos no exame dermatoscópico que no clínico, inclusive naquelas com inflamação, eczema perilesional e de tamanho pequeno. Vasos puntiformes relacionaram-se com inflamação, escoriação e eczema perilesional. CONCLUSÕES: A dermatoscopia das lesões de molusco mostrou-se superior ao exame dermatológico mesmo quando seu diagnóstico clínico torna-se difícil. A presença de orifícios, vasos e padrões vasculares específicos auxilia no seu diagnóstico e na diferenciação de outras lesões de pele.

BACKGROUNDS: Although easily diagnosed, molluscum contagiosum may present as a single lesion or as several small, inflamed lesions of difficult diagnosis. OBJECTIVE: To describe the dermoscopic characteristics of molluscum contagiosum and to compare the findings from clinical examination and dermoscopy. METHODS: Histopathologically confirmed lesions were evaluated clinically and dermoscopically in 57 patients. RESULTS: At clinical examination and dermoscopy of 211 lesions, orifices were visualized in 50.24% and 96.68% of the lesions, and vessels in 6.16% and 89.10%, respectively. The vascular patterns found in the 188 lesions in which vessels were found at dermoscopy were the crown (72.34%), radial (54.25%) and punctiform patterns (20.21%). Half of the 188 lesions had a combination of vascular patterns, with the flower pattern (a new vascular pattern) being found in 19.68% of cases. More orifices and vessels were identified at dermoscopy than at clinical examination, including cases with inflammation or perilesional eczema and small lesions. Punctiform vessels were associated with inflammation, excoriation and perilesional eczema. CONCLUSIONS: Dermoscopy performed on molluscum contagiosum lesions proved superior to dermatological examination even in cases in which clinical diagnosis was difficult. The presence of orifices, vessels and specific vascular patterns aids diagnosis, including differential diagnosis with other types of skin lesion.

Urticária aquagênica é forma rara de urticária física caracterizada por aparecimento de urticas após o contato com água, independente da temperatura. Há poucos casos descritos de urticária aquagênica e, destes, somente cinco da forma familiar. Apresentamos o primeiro relato de urticária aquagênica familiar no Brasil, acometendo mãe e filha. Ambas apresentavam urticas, principalmente após banho de chuveiro, independentemente da temperatura da água. A mãe referia ter o quadro há quatro anos, e a filha, desde o nascimento. Para diagnóstico, foram realizados testes de provocação com água, com aparecimento de lesões em ambas, e testes com dermografômetro, com cubo de gelo envolvido em plástico e de provocação para urticária colinérgica, sem o aparecimento de lesões, excluindo assim outras formas de urticária física.

Aquagenic urticaria is a rare form of physical urticaria, characterized by pruritic wheals that appear following contact with water, independently of its temperature. There are few reports of cases of aquagenic urticaria, and only five include the familial form. We present the first case of familial aquagenic urticaria in Brazil (mother and daughter). Both patients presented wheals following contact with water, especially when showering, regardless of its temperature. The mother reported onset of urticaria four years before and the daughter presented wheals since birth. For diagnostic purposes, they were submitted to a challenge test with water, and both subjects presented wheals, as well as to tests using ice cubes in plastic bag with dermographometer and challenge tests for cholinergic urticaria, with no appearance of lesions, excluding other forms of physical urticaria.
