- Abstract
Drug-induced hypersensitivity syndrome, also known as DRESS syndrome, is a serious and potentially fatal reaction that occurs in response to prolonged use (generally between 14 and 60 days) of certain drugs, and which has no predilection for gender or age group. It is believed that DRESS syndrome has a genetic basis and results from the interaction between metabolites of certain pharmacological groups, reactivation of latent viruses (especially from the Herpesviridae family), and a cellular immune response. The classic manifestation of DRESS syndrome includes a generalized rash accompanied by fever, eosinophilia, lymphadenopathy, and systemic involvement such as hepatitis, nephritis, or pneumonitis. With the continuous increase in the availability of drugs and the aging of the population, there is a favorable scenario for the development of adverse drug reactions. Physicians should be prepared for the early diagnosis of DRESS syndrome, the identification and immediate suspension of the drug involved, and also manage systemic involvement, which may require prolonged immunosuppressive therapy. This article provides an update on the clinical, physiopathological and therapeutic aspects of DRESS syndrome., (Copyright © 2024 Sociedade Brasileira de Dermatologia.

- Abstract
Background: Sporotrichosis is a neglected tropical disease and the most common subcutaneous mycosis, mainly caused by Sporothrix species, particularly S. brasiliensis, S. schenckii and S. globosa, which exhibit varying biological behaviours and virulence. The epidemic of sporotrichosis in Brazil, initiated in Rio de Janeiro in the late 1990s, rapidly spread to other states, including Amazonas in 2021. This study aimed to identify the specific Sporothrix species responsible for the human sporotrichosis outbreak in the Brazilian Amazon., Methods: A cross-sectional study was conducted by enrolling clinically suspected cases of sporotrichosis attended at a reference dermatologic centre, in Manaus (Brazil). Biological material was collected from their skin lesions for culture (Mycosel) and for species identification (qPCR)., Results: Sporothrix cultures were obtained from 150 cases. Sporotrichosis predominantly affected females (67.3%), aged 44.5 years on average, with lymphocutaneous lesions (72.7%). Sporothrix brasiliensis was identified in 89.3% of patients. Up to 83.3% of these patients reported contact with cats previously to the skin lesion, and the time-spatial progression of the human cases followed the notification of cases in cats, in the metropolitan region of Manaus., Conclusion: Sporothrix brasiliensis is the dominant species in the zoonotic outbreak of human sporotrichosis in the Brazilian Amazon, with cats identified as the primary vectors. Effective sanitary control measures, education and responsible pet ownership are crucial to mitigating zoonotic sporotrichosis' impact in Brazil and preventing its spread to neighbouring Latin American cities., (© 2024 John Wiley & Sons Ltd.)

- Abstract
Background: Sporotrichosis is the most common subcutaneous mycosis caused by Sporothrix spp. Traditionally, it is transmitted through injuries involving plant debris. However, over the past few decades, there has been an epidemic increase in human cases resulting from contact with infected animals, particularly cats, in various regions of Brazil. In this report, we report a notable increase in both human and animal cases within the Brazilian Amazon state., Methodology/principal Findings: An ecological study was conducted by analyzing official records of human and animal sporotrichosis diagnosed in the state of Amazon from 2020 to 2023. Data including patient demographics, clinical manifestations, mycological examination results, and species identification through PCR confirmation were evaluated. During this period, a total of 950 human cases and 2,823 animal cases of sporotrichosis were reported at an exponential rate, since no human cases were registered in 2020. The spatial and temporal dispersion of human sporotrichosis followed that of animal cases, moving from downtown areas to the periphery. Contact with infected animals was reported in 77.7% of cases, with cats being the most commonly implicated (73.5%). Only 66.7% of individuals underwent mycological examination. Among the positive cultures for Sporothrix spp., 65.4% were identified as S. brasiliensis. All patients were treated with systemic antifungals., Conclusions/significance: This study highlights a rising incidence of sporotrichosis among animals and humans in the Brazilian Amazon region over the past four years, with S. brasiliensis being the predominant agent. Collaborative efforts involving healthcare professionals, veterinarians, and public health authorities are crucial to implement effective control measures, educate populations at risk, and promote responsible guidance for pet guardians. These measures are essential to mitigate the burden of epidemic sporotrichosis in Brazil., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Mesquita et al.

- Abstract
Background: Leprosy is a neglected dermato-neurologic, infectious disease caused by Mycobacterium leprae or M. lepromatosis. Leprosy is treatable and curable by multidrug therapy/MDT, consisting of 12 months rifampicin, dapsone and clofazimine for multibacillary/MB patients and for 6 months for paucibacillary/PB patients. The relapse rate is considered a crucial treatment outcome. A randomized Controlled Clinical Trial (U-MDT/CT-BR) conducted from 2007‒2012 compared clinical outcomes in MB patients after 12 months regular MDT/R-MDT and 6 months uniform MDT/U-MDT in two highly endemic Brazilian areas., Objectives: To estimate the 10 years relapse rate of MB patients treated with 6 months U-MDT., Methods: The statistical analyses treated the data as a case-control study, sampled from the cohort generated for the randomized trial. Analyses estimated univariate odds ratio and applied logistic regression for multivariate analysis, controlling the confounding variables., Results: The overall relapse rate was 4.08 %: 4.95 % (16 out of 323) in the U-MDT group and 3.10 % (9 out of 290) in the regular/R-MDT group. The difference in relapse proportion between U-MDT and R-MDT groups was 1.85 %, not statistically significant (Odds Ratio = 1.63, 95 % CI 0.71 to 3.74). However, misdiagnosis of relapses, may have introduced bias, underestimating the force of the association represented by the odds ratio., Conclusions: The relapse estimate of 10 years follow-up study of the first randomized, controlled study on U-MDT/CT-BR was similar to the R-MDT group, supporting strong evidence that 6 months U-MDT for MB patients is an acceptable option to be adopted by leprosy endemic countries worldwide., Trial Registration: ClinicalTrials.gov: NCT00669643., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2024 Sociedade Brasileira de Infectologia.

- 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., (Copyright © 2023 Sociedade Brasileira de Dermatologia.

- 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., (Copyright © 2023 Sociedade Brasileira de Dermatologia.

- 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
Background: The increase in the zoonotic epidemic of sporotrichosis caused by Sporothrix brasiliensis, which started in the late 1990s in Rio de Janeiro and is now found in almost all Brazilian states, has been equally advancing in neighboring countries of Brazil. Changes in the clinical-epidemiological profile, advances in the laboratory diagnosis of the disease, and therapeutic difficulties have been observed throughout these almost 25 years of the epidemic, although there is no national consensus. The last international guideline dates from 2007., Objectives: Update the clinical classification, diagnostic methods and recommendations on the therapeutic management of patients with sporotrichosis., Methods: Twelve experts in human sporotrichosis were selected from different Brazilian regions, and divided into three work groups: clinical, diagnosis and treatment. The bibliographic research was carried out on the EBSCOHost platform. Meetings took place via electronic mail and remote/face-to-face and hybrid settings, resulting in a questionnaire which pointed out 13 divergences, resolved based on the opinion of the majority of the participants., Results: The clinical classification and laboratory diagnosis were updated. Therapeutic recommendations were made for the different clinical forms., Conclusion: Publication of the first national recommendation, carried out by the Brazilian Society of Dermatology, aimed at the Brazilian scientific community, especially dermatologists, infectologists, pediatricians, family medicine personnel, and laboratory professionals who work in the management of human sporotrichosis., (Copyright © 2022 Sociedade Brasileira de Dermatologia.
