BACKGROUND Leprosy is a highly neglected disease that is considered a serious public health problem in many countries. This illness is characterised by a variety of clinical and histopathological manifestations that are related to the patient immune response. OBJECTIVES This work aimed evaluate the profile of circulating immune mediators in the plasma from patients classified clinically as paucibacillary (PB), multibacillary (MB), households contacts (HHC), type1 leprosy reaction (T1R), type2 leprosy reaction (T2R) and control individuals without medical history of leprosy (CTL). METHODS To assessment of the plasma immune mediators was used multiplex microbeads immunoassay “Luminex”. FINDINGS The results showed that patients (PB) had a regulatory-biased profile, while MB revealed a pro-inflammatory trend of highly expressed biomarkers. HHC display conspicuously increased levels in the plasma of the chemokines (CCL2, CCL3, CCL4, CCL5 and CXCL8), pro-inflammatory cytokines (IFN-γ,TNF and IL-1β), modulating cytokines (IL-9 and IL-1Ra) and growth factors (PDGF, G-CSF and IL-2). Interestingly, HHC displayed superior production of IFN-γ as compared to other leprosy groups, indicating a putative protective role for this cytokine during chronic Mycobacterium leprae exposure. MAIN CONCLUSION Further investigations are currently underway to elucidate the potential of these mediators as biomarkers applicable to the diagnosis/prognosis of leprosy and also T1R and T2R leprosy reactions. countries response PB, PB , MB, (MB) HHC, (HHC) type T1R, TR T R (T1R) (T2R CTL.

ABSTRACT BACKGROUND: The prevalence of chronic kidney disease (CKD) has increased in the recent decades, along with the number of patients in the terminal stages of this disease, requiring transplantation. Some skin disorders are more frequent in patients with CKD and in renal transplant recipients (RTR). OBJECTIVES: To evaluate the frequency of skin diseases in RTR and patients with CKD receiving conservative treatment. DESIGN AND SETTING: This observational cross-sectional study recruited consecutive patients with CKD and RTR from a nephrology clinic at a teaching hospital in Brazil between 2015 and 2020. METHODS: Quantitative, descriptive, and analytical approaches were used. The sample was selected based on convenience sampling. Data were collected from dermatological visits and participants’ medical records. RESULTS: Overall, 308 participants were included: 206 RTR (66.9%, median age: 48 years, interquartile range [IQR] 38.0–56.0, 63.6% men) and 102 patients with CKD (33.1%, median age: 61.0 years, IQR 50.0–71.2, 48% men). The frequency of infectious skin diseases (39.3% vs. 21.6% P = 0.002) were higher in RTR than in patients with CKD. Neoplastic skin lesions were present in nine (4.4%) RTR and in only one (1.0%) patient with CKD. Among the RTR, the ratio of basal cell carcinoma to squamous cell carcinoma was 2:1. CONCLUSIONS: This study revealed that an increased frequency of infectious skin diseases may be expected in patients who have undergone kidney transplantation. Among skin cancers, BCC is more frequently observed in RTR, especially in those using azathioprine. BACKGROUND (CKD decades transplantation RTR. .

ABSTRACT Hepatic injuries in COVID-19 are not yet fully understood and indirect pathways (without viral replication in the liver) have been associated with the activation of vascular mechanisms of liver injury in humans infected with SARS-CoV-2. Golden Syrian hamsters are an effective model for experimental reproduction of moderate and self-limiting lung disease during SARS-CoV-2 infection. As observed in humans, this experimental model reproduces lesions of bronchointerstitial pneumonia and pulmonary vascular lesions, including endotheliitis (attachment of lymphoid cells to the luminal surface of endothelium). Extrapulmonary vascular lesions are well documented in COVID-19, but such extrapulmonary vascular lesions have not yet been described in the Golden Syrian hamster model of SARS-CoV-2 infection. The study aimed to evaluate microscopic liver lesions in Golden Syrian hamsters experimentally infected with SARS-CoV-2. In total, 38 conventional Golden Syrian hamsters, divided into infected group (n=24) and mock-infected group (n=14), were euthanized at 2-, 3-, 4-, 5-, 7-, 14-, and 15-days post infection with SARS-CoV-2. Liver fragments were evaluated by histopathology and immunohistochemical detection of SARS-CoV-2 Spike S2 antigens. The frequencies of portal vein endotheliitis, lobular activity, hepatocellular degeneration, and lobular vascular changes were higher among SARS-CoV-2-infected animals. Spike S2 antigen was not detected in liver. The main results indicate that SARS-CoV-2 infection exacerbated vascular and inflammatory lesions in the liver of hamsters with pre-existing hepatitis of unknown origin. A potential application of this animal model in studies of the pathogenesis and evolution of liver lesions associated with SARS-CoV-2 infection still needs further evaluation.

Resumo A hanseníase é uma doença infectocontagiosa que carrega forte estigma social. As décadas de internação compulsória em colônias resultaram no surgimento de comunidades em seus entornos que são importantes do ponto de vista epidemiológico e histórico pela alta prevalência da doença e pelas pessoas que viveram as consequências do isolamento e do estigma. Neste artigo é apresentado um estudo de análise do banco de dados, resultado de atividade de educação em saúde e prevenção da hanseníase, realizada em escolas de uma região de ex-colônia em Minas Gerais. O objetivo foi avaliar o conhecimento e os sentimentos sobre a hanseníase entre os estudantes. Para análise, utilizou-se estatística descritiva. Foram analisados 325 questionários respondidos por estudantes com idade entre 10 e 19 anos. Os resultados evidenciaram desconhecimento em relação à doença. O menor conhecimento em relação à doença se relacionou com sentimentos de indiferença e o maior conhecimento a angústia ou medo e altruísmo. Mais de 30% dos estudantes disseram nunca ter ouvido falar sobre hanseníase, mesmo morando em região de ex-colônia, o que sugere um silêncio que pode ser causa e consequência do estigma social que dificulta o controle da doença. Dessa forma, é necessário investir em educação em saúde em hanseníase nas áreas de ex-colônias como medida de vigilância epidemiológica e combate ao preconceito.

Abstract Leprosy is an infectious disease that carries a strong social stigma. Decades of compulsory hospitalization in colonies resulted in the emergence of communities in their surroundings that are important from an epidemiological and historical point of view. Usually they have a high prevalence of the disease and people who have experienced the consequences of isolation and stigma. This article presents a database analysis study, the result of health education and leprosy prevention activities, carried out in schools in an ex-colony region of Minas Gerais. The objective was to assess knowledge and feelings about leprosy among students. For analysis, descriptive statistics were used. We analyzed 325 questionnaires answered by students aged between 10 and 19 years. The results showed lack of knowledge about the disease. Less knowledge about the disease was related to feelings of indifference and greater knowledge to anguish or fear and altruism. More than 30% of students informed they have never heard about leprosy, even living in an ex-colony region, which suggests a silence that can be the cause and consequence of the social stigma that makes it difficult to control the disease. Thus, it is necessary to apply in health education in leprosy at areas of former colonies as a measure of epidemiological surveillance and prejudice fighting.

ABSTRACT: Vitamin A is an essential micronutrient to reproduction, development, normal growth, and function of the nervous system and vision, especially in growing animals. Hypovitaminosis A can affect any of these functions. The aim of this study was to describe the epidemiology, clinical signs, pathological aspects, and diagnostic approach in an outbreak of blindness in feedlot calves fed only grain. Five of 57 ten-month-old calves became blind after eight months at the feedlot. Clinical signs were mydriasis, absent pupillary and menace reflexes, bilaterally. Hypovitaminosis A was suspected and subsequently confirmed by low serum levels of vitamin A. One calf was euthanized and necropsied, and no gross findings were present. Histopathological lesions were restricted to the retina and characterized by degeneration and atrophy of the photoreceptor layer and some retinal scars. The calves were treated with intramuscular vitamin A injection at a dose of 5,000 international units (IU) per kilogram of body weight (kg BW) every 60 days until slaughter. Affected calves did not recover visual capacity, but no other cases occurred.

RESUMO: Vitamina A é um micronutriente essencial para reprodução, desenvolvimento, crescimento normal, além de participar do funcionamento do sistema nervoso central e visão, especialmente em animais em crescimento. Hipovitaminose A pode afetar qualquer uma dessas funções. O objetivo desse artigo é descrever a epidemiologia, sinais clínicos, aspectos patológicos e abordagem diagnóstica em um surto de cegueira em bezerros confinados alimentados apenas com grãos. De 57 bezerros de dez meses de idade, cinco ficaram cegos após oito meses no confinamento. Os sinais clínicos eram midríase, ausência de reflexo pupilar a luz e de ameaça, bilateralmente. Suspeitou-se de hipovitaminose A, que foi subsequentemente confirmada pelos baixos níveis séricos de vitamina A. Um bezerro foi eutanasiado e necropsiado, e alterações macroscópicas não foram encontradas. Lesões histopatológicas estavam restritas a retina e caracterizavam-se por degeneração e atrofia da camada de fotorreceptores, além de cicatrizes na retina. Os bezerros foram tratados com injeção intramuscular de vitamina A, na dose de 5.000 unidades internacionais (UI) por quilograma de peso vivo (Kg PV) a cada 60 dias, até o dia do abate. Os bezerros afetados não recuperaram a capacidade visual, mas novos casos não ocorreram.

Abstract Brazil is a large producer of dairy products, with an important role of milk in the country's economy beyond the nutritional aspects. In turn, the dairy industry is associated with environmental impacts, such as water and energy consumption, waste generation, liquid effluents, and atmospheric emissions. Life Cycle Assessment (LCA) is an environmental management tool used to measure the environmental impacts of goods, services, and products. This study used the LCA to assess the impacts resulting from the production of Minas Frescal and cured Minas cheese in an artisanal production facility in Casimiro de Abreu, Rio de Janeiro, Brazil. LCA results showed that the most significant environmental impacts were associated with the dairy farm under study, which is a source of greenhouse gases (GHG) emissions from livestock, particularly methane (CH4), produced through enteric fermentation and manure decomposition, mainly contributing for the impact categories of climate change (31.56%) and human toxicity with carcinogenic effects (35.46%). The cured Minas cheese presented higher impacts when compared to Minas Frescal cheese due to the larger volume of milk used in the manufacturing process. Thus, the present study suggested mitigation measures to lower the environmental impacts based on adjustments in animal feed to reduce atmospheric emissions. products countrys country s aspects turn consumption generation effluents (LCA goods services Abreu Janeiro GHG (GHG livestock CH4, CH4 CH , (CH4) decomposition 31.56% 3156 31 56 (31.56% 35.46%. 3546 35.46% . 35 46 (35.46%) process Thus (CH4 31.56 315 3 5 (31.56 354 35.46 4 (35.46% (CH 31.5 (31.5 35.4 (35.46 31.

Abstract This article addresses the compulsory seizing of children from vulnerable women in Brazil. Its objectives were: to discuss the violation of the right to maternity; to present the imposed restrictions especially on poor, black and indigenous women; the strategic control over their lives and children, and the resistance movements that oppose segregation. The sources of the research were: narratives of women in vulnerable situations, family members and health workers; interviews with strategic actors; document analysis; field journal. It became evident that vulnerabilities -linked to the criminalization of poverty and racial prejudice- have justified these separations. The lack of responsibility that State and society practice towards the support network for women, the devaluation of non-hegemonic productions of maternity, and the reinforcement of a ‘reason of the world’, that produces violence as a tool for exclusion establishing practical limits on the right to maternity. Women and children are disregarded in their singularities. Resistance movements have shown that intersectoral dialogues are an alternative to overcome discrimination and vulnerabilities.

ABSTRACT Background: Domestic pigeons carry pathogens in their droppings, posing a potential public health problem. Methods: The phenotypic and genotypic antimicrobial resistances of Staphylococcus aureus and Enterococcus faecium in the feces of urban pigeons near hospitals with intensive care units were measured. Results: Twenty-nine samples showed Enterococcus growth, whereas one was positive for S. aureus. The S. aureus isolate was sensitive to the antibiotics tested via antibiogram, however resistance genes were identified. E. faecium isolates showed phenotypic resistance to gentamicin, erythromycin, and ciprofloxacin. Conclusions: Antimicrobial profiles harmful to health were demonstrated in bacterial pathogens isolated from the external environment of hospitals.

Resumo: Testes rápidos que permitam a avaliação do potencial fisiológico são parâmetros essenciais para programas de produção de sementes e mudas com qualidade. O objetivo do trabalho foi estabelecer parâmetros de um método de avaliação do vigor de sementes de espécies nativas por meio da análise da produção de etanol, medido com etilômetro modificado. Foram testados seis lotes de Myracrodruon urundeuva, para cada lote foram colocadas 1,0 g e 2,0 g de sementes embebidas durante duas, quatro, seis, oito e 24 horas. Testou-se sete lotes de Cenostigma pyramidale, e cinco lotes de Amburana cearensis, onde foram colocadas 20 sementes embebidas durante duas, quatro, seis, oito e 24 h. A qualidade fisiológica das sementes foi avaliada, também, pelos testes de germinação e condutividade elétrica. A utilização de 1,0 g de sementes embebidas em 0,5 mL de água e avaliação de etanol em seis horas distinguiu lotes de M. urundeuva quanto ao vigor. Para as sementes de C. pyramidale, e de A. cearensis, 20 sementes embebidas em 1,0 mL de água em seis horas se mostrou mais eficiente. O teste de etanol mostrou ser rápido e preciso, permitindo diferenciar os lotes, assim como os testes de germinação e condutividade elétrica.

Abstract: Rapid tests that allow the assessment of physiological potential are essential parameters for quality seed and seedling production programs. The aim of this work was to establish parameters of a method for evaluating the vigor of seeds of native species through the analysis of ethanol production, measured with a modified alcohol meter. Six lots of Myracrodruon urundeuva were tested, and for each lot 1.0 g and 2.0 g of seeds were soaked for two, four, six, eight and 24 hours. Seven lots of Cenostigma pyramidale and five lots of Amburana cearensis were tested, where 20 seeds were soaked for two, four, six, eight and 24 h. The physiological quality of the seeds was also evaluated by germination and electrical conductivity tests. The use of 1.0 g of seeds soaked in 0.5 mL of water and evaluation of ethanol at six hours distinguished lots of M. urundeuva in terms of vigor. For C. pyramidale and A. cearensis, 20 seeds soaked in 1.0 mL of water and ethanol evaluation at six hours proved to be more efficient. The ethanol test proved to be fast and accurate, allowing differentiation of lots, as well as germination and electrical conductivity tests.

Abstract In this nonsystematic review, the complementary diagnosis, treatment, prevention, and control of human papillomavirus are discussed. The histopathology is addressed regarding its indications, main findings and limitations, as a complementary diagnostic method largely used by dermatologists. Electron microscopy is briefly reviewed, along with its contribution to the accumulated knowledge on HPV, as well as the relevance of research in using this technology for future advances in diagnosis and treatment. Molecular information about the virus is continuously increasing, and the practical applications of HPV serology, molecular identification and genotyping are discussed. Vaccines are a valuable tool in primary HPV infection prevention and are now available in many countries; their composition, indications, and adverse effects are revisited. Local and systemic treatment options are reviewed and off-label prescriptions are discussed. Finally, health education focusing on HPV infection as a sexually transmitted infection of worldwide relevance and the many barriers to improve primary and secondary prevention are addressed.

Abstract Infection with human papilloma virus (HPV) is related to a great number of cutaneous and mucosal manifestations. The spectrum of HPV ranges from inapparent infections, through various clinical benign presentations including cutaneous and mucosal disease, to malignant and premalignant conditions. New HPV types are currently described in the literature; many of them are characterized as high-risk types due to their oncogenic potential. Knowledge regarding their epidemiology and pathogenesis is important to understand not only infection and disease processes, but also to formulate the clinical and laboratory basis for diagnosis, therapeutics, and prophylactic measures. This non-systematic review aims to discuss and to update those aspects, with an emphasis on relevant topics for dermatologists. HPV infection and related diseases in the Brazilian scenario are highlighted, including common dermatologic conditions seen at clinics as well as the condition of a public health problem as a sexually transmitted infection. The oncogenicity of the virus and the variety of clinical outcomes - especially in the immunocompromised individuals - are addressed.

RESUMO O objetivo deste relato é descrever os dados clinicopatológicos e de tratamento de uma paciente, 86 anos, com corno cutâneo (CC) nos tecidos orais (lábio inferior) e compará-los com outros estudos publicados, fazendo uma revisão da literatura. Após biópsia excisional, o exame histopatológico revelou CC associado a queilite actínica. Apenas 23 casos semelhantes já foram relatados. Durante nossa pesquisa, verificamos que o CC afetou principalmente o lábio inferior de homens brancos em uma ampla faixa etária. A excisão deve ser o tratamento de escolha, pois ela possibilita a realização de exame histopatológico da lesão subjacente, já que a maioria dos casos foi associada a lesões pré-malignas/malignas.

ABSTRACT The aim is to describe the clinical-pathological and treatment data of a patient with a cutaneous horn (CH) arising on oral tissues and to compare this with a literature-review. This case affects the lower-lip of an 86-years-old female. After excisional biopsy, the histopathological examination revealed a CH associated with actinic cheilitis. Only 23 similar cases have been reported in literature. At this site CH mainly affects the lower-lip of white males in a wide-age range. Excision should be the treatment of choice to enable pathological examination of the underlying lesion, since most cases were associated with pre-malignant/malignant lesions.

RESUMEN El objetivo es describir los datos clinicopatológicos y de tratamiento de una paciente de 86 años con un cuerno cutáneo (CC) en los tejidos orales (labio inferior) y compararlos con una revisión de la literatura. Tras la biopsia escisional, el examen histopatológico reveló un CC asociado a queilitis actínica. Solo se han informado 23 casos similares en la literatura. El estudio ha revelado que el CC afecta principalmente al labio inferior de los hombres blancos en un amplio rango de edad. La escisión debe ser el tratamiento de elección para permitir el examen patológico de la lesión subyacente, ya que la mayoría de los casos se asociaron con lesiones premalignas/malignas.
