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 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.

Abstract Background: There are few epidemiological studies of urticaria, published in the indexed literature (PubMed/Medline). Objective: The study aimed to evaluate the epidemiological and clinical data among patients with urticaria/angioedema attending a reference clinic in Brazil. Methods: Two hundred sixty-seven patients were evaluated retrospectively considering demographic data, time course of the disease, triggering symptoms, the presence of angioedema, complementary laboratory tests including total blood count, reactive-C protein, erythrocyte sedimentation rate, IgE serum levels, and other, as necessary. Results: The most commonly diagnosed type of urticaria was chronic spontaneous urticaria (56.93%). Angioedema was associated with chronic urticaria in 108 patients (40.08%). Study limitations: Unicentered and retrospective. Conclusion: Some relevant findings in this study are the observation of a female prevalence of cases (4-females: 1-man), a result more elevated than demonstrated in previous studies in Europe and Asia, the median age was 43-years old and the delay of time between the diagnosis of urticaria and the admission for treatment in a specialized center was approximately 2-years. Other multicenter studies can better establish these differences in Brazilian patients.

Abstract The technological advancement of the pharmaceutical industry, resulting from the techniques of molecular biology and expansion of the knowledge of immunopathogenesis, has modified the therapeutic arsenal used in dermatology. Scientific research and regulatory standards cause drug costs to rise, thus making their use impossible in most public policies. In order to make high-cost drugs viable in the public health network, the Specialized Pharmaceutical Assistance Component was created. However, despite the frequent incorporation of medications, the constant requirement of drugs through lawsuits leads to exorbitant costs to the state budget. The present work analyzed through a descriptive observational study, the current situation of the Specialized Component and the involvement of medicines used in dermatology, through legal reviews, financial analyses, and medical articles, aiming at future incorporations for the specialty. When assessing the legal demands for dermatological drugs in the state of São Paulo, the specialty still has a low participation and psoriasis is the main disease involved in requiring drugs through the judicial system in the state. New methods of access to raw materials must be created to reduce legal issues. Cost-effectiveness and public planning studies are mandatory for incorporating new dermatological therapies.

Abstract Background: The pathophysiology of urticaria is still poorly understood. Recent studies demonstrate that the activation of coagulation is correlated with the clinical activity of Chronic Spontaneous Urticaria. Coagulation and inflammation are strongly linked. Objectives: To correlate the severity and activity of Chronic Spontaneous Urticaria with the levels of D-dimer, C-reactive protein, and autologous serum test in patients with Chronic Spontaneous Urticaria. Methods: The study included 55 patients diagnosed with chronic spontaneous urticaria. D-dimer levels were measured using enzyme-linked fluorescent assay and C-reactive protein levels were measured using the nephelometric method; autologous serum testing was performed on patients who discontinued antihistamine therapy. The severity of the disease was assessed using the urticaria activity score. Results: patients with severe, spontaneous, and difficult-to-control chronic urticaria had elevated serum levels of D-dimer, as well as a positive autologous serum test. Little correlation was demonstrated between the severity of chronic spontaneous urticaria and the levels of C-reactive protein. Conclusion: The authors concluded that patients with severe Chronic Spontaneous Urticaria showed signs of activated fibrinolysis. Most patients with high clinical scores had high D-dimer values. Patients with positive results for the autologous serum test also had more severe Chronic Spontaneous Urticaria and needed more drugs to control the disease. Finally, little correlation was found between C-reactive protein levels and disease severity. Study limitations: The main limitation was the small sample of patients. In the present patients, it was demonstrated that serum D-dimer levels and the autologous serum test can act as predictive markers of severity and activity of Chronic Spontaneous Urticaria.

ABSTRACT Tuberculosis verrucosa cutis is a rare medical condition that is caused by the inoculation of Mycobacterium tuberculosis into the skin of a previously sensitized individual. This clinical form of tuberculosis corresponds to 1–2% of all cases of tuberculosis and due to the paucibacillary characteristic of the lesions, patients can be misdiagnosed, accounting for the chronification of the skin infection. Herein, we report the case of a 26-year-old male farmer, presenting plaques with verrucosa and hyperkeratosis features in the left thigh and buttocks during 15 years. M. tuberculosis was identified by PCR and the patient was treated with standard anti-tuberculosis drugs, with subsequent improvement of the skin lesions.

Abstract Background: Mohs micrographic surgery is worldwide used for treating skin cancers. After obtaining tumor-free margins, choosing the most appropriate type of closure can be challenging. Objectives: Our aim was to associate type of surgical reconstructions after Mohs micrographic surgery with the characteristics of the tumors as histological subtype, anatomical localization and especially number of surgical stages to achieve complete excision of the tumour. Methods: Transversal, retrospective analyses of medical records. Compilation of data such as gender, age, tumor location, histological subtype, number of stages to achieve clear margins and type of repair used. Results: A total of 975 of facial and extra-facial cases were analyzed. Linear closure was the most common repair by far (39%) and was associated with the smallest number of Mohs micrographic surgery stages. This type of closure was also more common in most histological subtypes and anatomical locations studied. Using Poisson regression model, nose defects presented 39% higher frequency of other closure types than the frequency of primary repairs, when compared to defects in other anatomic sites (p< 0.05). Tumors with two or more stages had a 28.6% higher frequency of other closure types than those operated in a single stage (p< 0.05). Study limitations: Retrospective study with limitations in obtaining information from medical records. The choice of closure type can be a personal choice. Conclusions: Primary closure should not be forgotten especially in surgical defects with fewer stages and in non-aggressive histological subtypes in main anatomic sites where Mohs micrographic surgery is performed.

Resumo O termo de consentimento informado é fundamental na relação jurídica entre médico e paciente. Visando avaliar seu impacto na sentença judicial, realizou-se estudo retrospectivo de 70 processos de responsabilidade civil envolvendo procedimentos médicos estéticos cirúrgicos e não cirúrgicos com termo de consentimento assinado pelos pacientes. Os casos analisados, julgados entre 2014 e 2016, foram selecionados nos sites dos tribunais brasileiros e classificados em dois grupos: médicos absolvidos (51%) e condenados (49%). No primeiro grupo, 39% das absolvições se embasaram na apresentação adequada do termo de consentimento informado, enquanto, no segundo, 50% dos médicos foram condenados por não o ter incluído. Portanto, o termo de consentimento informado se destaca nos julgamentos de erro médico. O dever de informar é um dos pilares da responsabilidade civil desse profissional e, quando negligenciado, constitui fator substancial para condenação.

Abstract The informed consent form is essential in the physician-patient relationship. To evaluate its impact on court decisions, we conducted a retrospective study of 70 civil suits involving surgical and non-surgical aesthetic medical procedures with an informed consent form signed by patients. The cases, judged between 2014 and 2016, were selected from Brazilian courts websites and classified into two groups: acquitted (51%) and convicted (49%) doctors. In the first group, 39% of acquittals were based on the proper presentation of the informed consent form, whereas in the second 50% of the professionals were convicted for not including the document. The informed consent thus stands out when judging medical errors, and the duty to warn is one of the pillars of the professional liability and, when neglected, becomes a substantial factor for their conviction.

Abstract Vasculitis is a group of several clinical conditions in which the main histopathological finding is fibrinoid necrosis in the walls of blood vessels. This article assesses the main dermatological aspects relevant to the clinical and laboratory diagnosis of small- and medium-vessel cutaneous and systemic vasculitis syndromes. The most important aspects of treatment are also discussed.

Abstract Multinucleate cell angiohistiocytoma is a rare, benign vascular proliferation of unknown etiology. It occurs mainly in middle-aged women and usually affects the acral regions; the lesions appear as discrete, grouped, and asymptomatic violaceous papules. Histopathology shows proliferation and dilated small vessels in the papillary dermis, fibrous stroma with thickened collagen bundles, and multinucleated giant cells. To date, there are approximately 140 cases described in the indexed literature. This report presents the case of a 62-year-old woman with a typical clinical condition, who chose not undergo treatment, considering the benign character of her illness. The clinical and immunohistological aspects of this unusual dermatological entity are emphasized.

Abstract The term vasculitis refers to the inflammation of vessel walls. It may range in severity from a self-limited disorder in one single organ to a life-threatening disease due to multiple organ failure. It has many causes, although they result in only a few histological patterns of vascular inflammation. Vessels of any type and in any organ can be affected, a fact that results in a broad variety of signs and symptoms. Different vasculitides with indistinguishable clinical presentations have quite different prognosis and treatments. This condition presents many challenges to physicians in terms of classification, diagnosis, appropriate laboratory workup, and treatment. Moreover, it compels a careful follow-up. This article reviews the Chapel-Hill 2012 classification, etiology, recent insights in pathophysiology, some important dermatological clues for the diagnosis and summarizes treatment of some of these complex vasculitis syndromes.
