RESUMEN
Post-menopause hyperandrogenism is a condition that needs careful evaluation. Aromatase inhibitors (AI), which are important in the management of positive estrogen breast cancer, and chronic kidney disease (CKD) can puzzle the evaluation of this condition. A postmenopause female with type-2 diabetes and advanced CKD was attended due to progressive virilization, which has started after the introduction of an AI for breast cancer 5 years earlier. Clinical and radiological investigation has confirmed a pure Leydig cell tumor as source of hyperandrogenism. Re-evaluation of the breast tumor immunohistochemistry has shown positive androgen receptor expression and negative expression for estrogen, progesterone and HER-2 receptors. Even though an ovarian tumor was the source of androgen excess, we discuss that AI could exert a slight contribution to patient's virilization by reducing estradiol counterbalance. Also, although the onset of hyperandrogenic symptoms was unclear, we could not exclude that the ovarian tumor had produced enough androgens to play a role in breast tumor progression. This case report supports the literature regarding the possible association between Leydig cell tumor and androgen-receptor-positive breast cancer development. Finally, progressive hyperandrogenic symptoms in postmenopause, even under AI therapy or the presence of advanced CKD, impose a more detailed investigation.

INTRODUCTION: SARS-CoV-2 is the pathogen of COVID-19. The virus is composed of the spike, membrane and envelope. On physiological smell, odoriferous substances bind to proteins secreted by sustentacular cells in order to be processed by olfactory receptor neurons. Olfactory disorder is one of the main manifestations of COVID-19, however, research is still required to clarify the mechanism involved in SARS-CoV-2 induced anosmia. OBJECTIVE: This article aims to analyze current scientific evidence intended to elucidate the pathophysiological relationship between COVID-19 and the cause of olfactory disorders. METHODS: Pubmed, Embase, Scopus and ScienceDirect were used to compose this article. The research was conducted on November 24th, 2020. Original articles with experimental studies in human, animal and in vitro, short communications, viewpoint, published in the English language and between 2019 and 2020 were included, all related to the pathophysiological relationship between olfactory disorders and COVID-19 infection. RESULTS: Both human cell receptors ACE2 and TMPRSS2 are essential for the SARS-CoV-2 entrance. These receptors are mostly present in the olfactory epithelium cells, therefore, the main hypothesis is that anosmia is caused due to damage to non-neuronal cells which, thereafter, affects the normal olfactory metabolism. Furthermore, magnetic resonance imaging studies exhibit a relationship between a reduction on the neuronal epithelium and the olfactory bulb atrophy. Damage to non-neuronal cells explains the average recovery lasting a few weeks. This injury can be exacerbated by an aggressive immune response, which leads to damage to neuronal cells and stem cells inducing a persistent anosmia. Conductive anosmia is not sufficient to explain most cases of COVID-19 induced anosmia. CONCLUSION: Olfactory disorders such as anosmia and hyposmia can be caused by COVID-19, the main mechanism is associated with olfactory epithelium damage, targeting predominantly non-neuronal cells. However, neuronal cells can also be affected, worsening the condition of olfactory loss.

Severe Acute Respiratory Syndrome Coronavirus 2 is part of the Cononaviridae family and is the causative agent of the 2019 (Covid-19) Coronavirus pandemic declared by the World Health Organization in March, 2020. This virus has a high rate of transmission, affecting several individuals, and has caused thousands of deaths. The clinical manifestations of Severe Acute Respiratory Syndrome Coronavirus 2 infection are not restricted only to the respiratory tract, and there is an express involvement of the cardiovascular system with a higher risk of death in this group. In such patients there is an overactivation of renin-angiotensin-aldosterone system, which promotes an increase in the expression of angiotensin-converting enzyme - 2 that acts as a receptor for the SPIKE protein expressed by the virus and enables the interaction between the host cell and Severe Acute Respiratory Syndrome Coronavirus 2. This process of infection causes a hyperinflammatory state that increases the inflammatory markers of cardiac injury. Hence, an adequate understanding and clinical guidance regarding the monitoring, and controlling the damage in these patients is essential to avoid worsening of their clinical condition and to prevent death.

PURPOSE: In laparoscopic incisional hernia repair, meshes with a tissue-separating barrier are positioned intraperitoneally. Despite this property, the close contact between mesh and viscera involves a risk of adhesion formation. Some natural products, such as red propolis (RP), could reduce these adhesions owing to their anti-inflammatory properties. This study aimed to compare two different intraperitoneal meshes with respect to their characteristics of adhesion formation, histological findings and evaluate the role of RP in the development of these adhesions. METHODS: 40 Wistar rats received placement of two different meshes (Symbotex and Dynamesh IPOM) on peritoneum. The animals were divided into two groups: control group (mesh) and treatment group (mesh and RP). After 7 and 14 days, 20 animals of each group underwent midline laparotomy to determine the adhesions and histological characteristics. RESULTS: Out of the 40 animals, there were two deaths in the test group and two in the control group. All animals in both groups developed adherence to the mesh. At postoperative day (POD) 7, two Symbotex meshes presented firm adhesions and at POD 14, two Dynamesh meshes had firm adhesions as well. The comparison between the meshes under the effect of RP in relation to the control group showed no statistical difference. CONCLUSIONS: Both meshes showed intraperitoneal adhesions in all evaluated samples with similar results on the characteristics of adhesions. RP showed no effect on the incidence or gradation of intraperitoneal adhesions with the mesh.

Resumo Introdução SARS‐CoV‐2 é o patógeno da Covid‐19. O vírus é composto pela proteína spike (espigão), a membrana e o envelope. No olfato fisiológico, as substâncias odoríferas se ligam a proteínas secretadas pelas células sustentaculares para serem processadas pelos neurônios receptores olfativos. O distúrbio olfativo é uma das principais manifestações da Covid‐19; entretanto, pesquisas ainda são necessárias para esclarecer o mecanismo envolvido na anosmia induzida pela SARS‐CoV‐2. Objetivos Este artigo tem como objetivo analisar as evidências científicas atuais destinadas a elucidar a relação fisiopatológica entre a Covid‐19 e a causa dos distúrbios olfativos. Método As bases de dados Pubmed, Embase, Scopus e ScienceDirect foram usadas para compor este artigo. A pesquisa foi feita em 24 de novembro de 2020. Foram incluídos artigos originais com estudos experimentais em seres humanos, animais e estudos in vitro, comunicações breves, pontos de vista, publicados na língua inglesa e entre 2019 e 2020, todos relacionados à relação fisiopatológica entre distúrbios olfativos e infecção por Covid‐19. Resultados Ambos os receptores de células humanas ACE2 e TMPRSS2 são essenciais para a penetração do SARS‐CoV‐2. Esses receptores estão presentes principalmente nas células do epitélio olfativo; portanto, a principal hipótese é que a anosmia é causada por lesão de células não neuronais que, a partir daí, afeta o metabolismo olfativo normal. Além disso, estudos de ressonância magnética mostram uma relação entre a redução do epitélio neuronal e a atrofia do bulbo olfatório. Danos às células não neuronais explicam o tempo médio de recuperação, que demora algumas semanas. Essa lesão pode ser exacerbada por uma resposta imune agressiva, que leva a danos às células neuronais e células‐tronco, induz uma anosmia persistente. A anosmia condutiva não é suficiente para explicar a maioria dos casos de anosmia induzida por Covid‐19. Conclusão Distúrbios olfativos como anosmia e hiposmia podem ser causados pela Covid‐19 e o principal mecanismo está associado à lesão do epitélio olfativo, tem como alvo células predominantemente não neuronais. Porém, células neuronais também podem ser afetadas, o que piora o quadro de perda olfativa.

The present work aims to report a case of Buschke-Löwenstein tumor (BLT), which is a mass of genital warts that usually affects immunosuppressed people. The reported case was diagnosed in a young patient with no known immunosuppression. Several tests were performed to confirm the diagnostic hypothesis, including immunohistochemistry, histological, molecular and imaging analysis. The results obtained were confirmatory in all analyses, except in the molecular one. Because BLT is a rare condition, there is still great literary heterogeneity regarding the ideal treatment, but some options can be considered, such as excision and radiotherapy. (AU)

OBJECTIVE: to produce improvements in transfusion practices through the implementation of an educational program for health professionals in a university hospital. METHODS: this is an interventional and prospective study, with pre- and postanalysis of an educational intervention. The research was developed at the University Hospital of the Universidade Federal de Sergipe, involving participation of health professionals in the stage of training, during the month of February 2011, in addition to the monitoring of blood transfusions performed in the pre- and post-intervention periods. Transfusion practices were investigated upon request for transfusion or devolution of unused blood components. Knowledge of health professionals was assessed based on the responses to a questionnaire about transfusion practices. RESULTS: during the educative campaign, 63 professionals were trained, including 33 nurses or nursing technicians and 30 physicians. Among the doctors, there was a statistically significant gain of 20.1% in theoretical knowledge (p=0.037). Gain in the nursing group was even higher: 30.4% (p=0.016). The comparative analysis of transfusion request forms showed a non-significant decrease from 26.7 to 19.5% (p=0.31) in all forms with incomplete information. We also observed a statistically significant improvement in relation to the filling of four items of transfusion request. CONCLUSION: there was a significant improvement of the entire process related to blood transfusions after interventional project conducted in February 2011.

INTRODUCTION: The most common pathogen in bacteria lpharyngotonsillitis is group A ß-hemolytic streptococcus, although groups B, C, F,and G have also been associated with pharyngotonsillitis. OBJECTIVE: To assess the levels of the cytokines TNF-α, IL-6,IL-4, and IL-10 in bacterial pharyngotonsillitis caused by group A and non-A (groups B, C, F and G) ß-hemolytic streptococcus. METHODS: The study was conducted at a pediatric emergency care unit. The sample comprised children (5-9 years old) with acute bacterial pharyngotonsillitis diagnosed between December of 2011 and May of 2012. The research involved collection of blood samples from the patients, enzyme-linked immunosorbent assay detection of TNF-α, IL-6,IL-4, and IL-10, and collection of two oropharyngeal swabs for bacterial isolation. Additionally, the medical history of the study participants was also collected. RESULTS: In the studied group (mean age: 5.93 years), higher pharyngotonsillitis incidence was observed in the female gender (64.76%). Higher incidence of tonsillar exudates was observed with groups A and C. No statistically significant differences in cytokine levels were observed among groups. However, the group A and the control group showed a difference in the IL-6 level (p=0.0016). CONCLUSIONS: The Groups A and C showed higher cytokine levels than the Groups B and control, suggesting similar immunological patterns.

OBJECTIVES: to evaluate and indicate the procedure to be followed in the health unit, both for diagnosis and the treatment of acute exogenous intoxications by carbamates or organophosphates. METHODS: a descriptive study based on retrospective analysis of the clinical history of patients diagnosed with intoxication by carbamates or organophosphates admitted at the emergency unit of the Hospital de Urgências de Sergipe Governador João Alves (HUSE) between January and December of 2012. Some criteria were evaluated, such as: intoxicating agent; patient's age and gender; place of event, cause, circumstances and severity of the intoxication; as well as signs and symptoms of the muscarinic, nicotinic and neurological effects. RESULTS: seventy patients (average age: 25 ± 19.97) formed the study's population. It was observed that 77.14% of them suffered carbamate intoxication. However, organophosphate intoxications were more severe, with 68.75% of patients presenting moderate to severe forms. Suicide attempt was the leading cause of poisoning, with 62 cases (88.57% of total). Atropine administration was an effective therapeutic approach for treating signs and symptoms, which included sialorrhea (p = 0.0006), nausea (p = 0. 0029) and emesis (p < 0.0001). The use of activated charcoal was shown effective, both in combating the signs and symptoms presented by both patient groups (p < 0.0001). CONCLUSION: it is concluded that the use of atropine and activated charcoal is highly effective to treat the signs and symptoms developed by patients presenting acute exogenous intoxication by carbamates or organophosphates.

INTRODUCTION: Rheumatic Fever represents a serious public health problem in developing countries, with thousands of new cases each year. It is an autoimmune disease, which occurs in response to infection by streptococcus A. OBJECTIVE: The aim of this study was to evaluate the immunolabeling and protein expression for endothelin-1 and 3 (ET-1, ET-3) and its receptors (ETA, ETB) in rheumatic mitral valves. METHODS: Immunohistochemistry was used to identify ET-1/ET-3 and ETA/ETB receptors in rheumatic and control mitral valves. Quantitative analysis of immunostaining for ET-1/ET-3 and ETA/ETB receptors was performed. In addition, western blot analysis was carried out to assess protein levels in tissue samples. RESULTS: ET-1 and ETA receptor immunostaining predominated in stenotic valves, mainly associated with fibrotic regions, inflammatory areas and neovascularization. Quantitative analysis showed that the average area with positive expression of ET-1 was 18.21 ± 14.96%. For ETA and ETB, the mean expressed areas were respectively 15.06 ± 13.13% and 9.20 ± 11.09%. ET-3 did not have a significant expression. The correlation between the expression of both endothelin receptors were strongly positive (R = 0.74, P = 0.02), but the correlation between ET-1 and its receptor were negative for both ETA (R = -0.37, P = 0.25), and ETB (R = -0.14, P = 0.39). This data was supported by western blot analysis. CONCLUSION: The strong correlation between ET-1 and its receptors suggests that both play a role in the pathophysiology of rheumatic mitral valve stenosis and may potentially act as biomarkers of this disease.

OBJECTIVE: To evaluate the immunological profile and gene expression of endothelin-1 (ET-1) in mitral valves of patients with rheumatic fever originated from a reference service in cardiovascular surgery. METHODS: This was a quantitative, observational and cross-sectional study. Thirty-five subjects (divided into four groups) participated in the study, 25 patients with chronic rheumatic heart disease and ten control subjects. The mean age of the sample studied was 34.5 years. Seventeen of them (48.58%) were male and 18 (51.42%) were female. Inflammatory cytokines (TNF-α, IL-4 and IL-10) were measured and ten mitral valves of patients who underwent first valve replacement were collected for determination of gene expression of endothelin-1 by real time PCR. RESULTS: Among the groups studied (patients vs. controls), there was a statistically significant difference in IL-10 levels (P=0.002), and no differences in other cytokines. Expression of endothelin-1 was observed in 70% of samples. Quantitatively, average of ET-1 expression was 62.85±25.63%. CONCLUSION: Inflammatory cytokine IL-10 participates in the maintenance of chronicity of rheumatic fever in patients who underwent valve replacement and those who are undergoing medical treatment. The expression of endothelin-1 in heart valve lesions in patients undergoing mitral valve replacement confirms its association with inflammatory activity in rheumatic fever.

Abstract Aim: To assess the prevalence, quality of life (QoL), and the damages caused by PH, in the professional and personal scope of Physical Education academics with Primary Hyperhidrosis (PH). Methods: A descriptive, exploratory, qualitative and quantitative cross-sectional study was carried out. Twenty-five students from the physical education course at Tiradentes University, Aracaju-SE, were interviewed from August to November 2017. Validated questionnaires were used on PH's influence in academic activities and QoL. absolute and relative frequencies in the case of categorical variables and measures of trend and central variability in the case of numerical variables. Results: The prevalence of PH in students of Physical Education was 11.11%, mainly in combined sites, such as palmoplantar, and with no difference between the sexes. The symptoms started mostly during childhood and adolescence. Most of the interviewees (92%) reported difficulties with activities such as sports, use of personal protective equipment, handling of work equipment and instruments, and exacerbation in stress situations. They reported significant harm to QoL in situations of greeting people with handshakes, writing, wearing socks and dancing socially. Conclusion: Although PH is a disease that negatively impacts the QoL, it is still little known in the academic world with little demand for medical help. Therefore, it is necessary greater dissemination of the disease for its early diagnosis, related to the intensity of the sweating for a better therapeutic approach.

OBJECTIVES: Rheumatic fever is a highly prevalent disease in Brazil, and it poses a major public health problem. It is the leading cause of acquired heart disease in childhood and adolescence. The aim of this study was to evaluate the gene expression of ET-3 and its receptors, in replaced rheumatic mitral valves. METHODS: We studied the gene expression of endothelin-3 (ET-3) and its receptors, endothelin receptor A and endothelin receptor B (ETr-A and ETr-B), in the rheumatic mitral valves of 17 patients who underwent valve replacement surgery. The samples also underwent a histological analysis. RESULTS: Our data showed that almost all patients, regardless of individual characteristics such as gender or age, expressed the endothelin receptor genes, but did not express the genes for ET-3. In quantitative analysis, the ETr-A/GAPDH mean ratio was 33.04 ± 18.09%; while the ETr-B/GAPDH mean ratio was 114.58 ± 42.30%. Regarding histopathological individual features, the frequency of fibrosis is 100%, 88.23% of mononuclear infiltrate, 52.94% of neovascularization, 58.82% of calcification and absence of ossification. CONCLUSION: The presence of receptors ETr-A and ETr-B in rheumatic mitral valves suggests its interaction with the system of circulating endothelins, particularly ETr-B (known for acting in the removal of excess endothelin) detected in a greater proportion, which could explain the lack of expression of endothelin in rheumatic mitral valve, process to be elucidated.

SummaryObjective:to produce improvements in transfusion practices through the implementation of an educational program for health professionals in a university hospital.Methods:this is an interventional and prospective study, with pre- and postanalysis of an educational intervention. The research was developed at the University Hospital of the Universidade Federal de Sergipe, involving participation of health professionals in the stage of training, during the month of February 2011, in addition to the monitoring of blood transfusions performed in the preand post-intervention periods. Transfusion practices were investigated upon request for transfusion or devolution of unused blood components. Knowledge of health professionals was assessed based on the responses to a questionnaire about transfusion practices.Results:during the educative campaign, 63 professionals were trained, including 33 nurses or nursing technicians and 30 physicians. Among the doctors, there was a statistically significant gain of 20.1% in theoretical knowledge (p=0.037). Gain in the nursing group was even higher: 30.4% (p=0.016). The comparative analysis of transfusion request forms showed a non-significant decrease from 26.7 to 19.5% (p=0.31) in all forms with incomplete information. We also observed a statistically significant improvement in relation to the filling of four items of transfusion request.Conclusion:there was a significant improvement of the entire process related to blood transfusions after interventional project conducted in February 2011.
ResumoObjetivo:produzir melhorias em práticas transfusionais a partir da implementação de um programa educacional para profissionais de saúde em um hospital universitário.Métodos:este é um estudo intervencional e prospectivo, com análises pré e pós-intervenção educacional. A pesquisa foi desenvolvida no Hospital Universitário da Universidade Federal de Sergipe, envolvendo a participação de profissionais de saúde no estágio de capacitação, durante o mês de fevereiro de 2011, além da monitorização de transfusões sanguíneas feitas nos períodos pré e pós-intervencionais. A busca por práticas transfusionais foi checada via requerimentos de transfusão e devolução de hemocomponentes não utilizados. O conhecimento dos profissionais de saúde foi medido por meio de questionário relacionado a práticas transfusionais.Resultados:durante a campanha educativa, foram capacitados 63 profissionais de saúde, sendo 33 enfermeiros e técnicos de enfermagem e 30 médicos. Entre os médicos, houve um ganho estatisticamente significante de 20,1% nos conhecimentos teóricos (p=0,037). O ganho no grupo da enfermagem foi ainda maior, de 30,4% (p=0,016). A análise comparativa dos formulários de requisição transfusional mostrou uma diminuição não significativa de 26,7 para 19,5% (p=0,31) em todas as formas de preenchimento incompleto. Observou-se uma melhoria estatisticamente significativa no preenchimento de quatro itens da requisição transfusional.Conclusão:houve melhorias significativas em todo o processo relacionado às transfusões sanguíneas após intervenção conduzida em fevereiro de 2011.

Abstract Introduction: Rheumatic Fever represents a serious public health problem in developing countries, with thousands of new cases each year. It is an autoimmune disease, which occurs in response to infection by streptococcus A. Objective: The aim of this study was to evaluate the immunolabeling and protein expression for endothelin-1 and 3 (ET-1, ET-3) and its receptors (ETA, ETB) in rheumatic mitral valves. Methods: Immunohistochemistry was used to identify ET-1/ET-3 and ETA/ETB receptors in rheumatic and control mitral valves. Quantitative analysis of immunostaining for ET-1/ET-3 and ETA/ETB receptors was performed. In addition, western blot analysis was carried out to assess protein levels in tissue samples. Results: ET-1 and ETA receptor immunostaining predominated in stenotic valves, mainly associated with fibrotic regions, inflammatory areas and neovascularization. Quantitative analysis showed that the average area with positive expression of ET-1 was 18.21±14.96%. For ETA and ETB, the mean expressed areas were respectively 15.06±13.13% and 9.20±11.09%. ET-3 did not have a significant expression. The correlation between the expression of both endothelin receptors were strongly positive (R=0.74, P=0.02), but the correlation between ET-1 and its receptor were negative for both ETA (R=-0.37, P=0.25), and ETB (R=-0.14, P=0.39). This data was supported by western blot analysis. Conclusion: The strong correlation between ET-1 and its receptors suggests that both play a role in the pathophysiology of rheumatic mitral valve stenosis and may potentially act as biomarkers of this disease. .
Resumo Introdução: A febre reumática representa um sério problema de saúde pública em países em desenvolvimento, com milhares de novos casos a cada ano. Ela é uma doença autoimune que ocorre em resposta à infecção por estreptococos do grupo A. Objetivo: O objetivo deste estudo foi avaliar a expressão proteica e imunohistoquímica para a endotelina-1 e 3 (ET-1 e ET-3) e seus receptores (ETA e ETB) em valvas mitrais reumáticas. Métodos: Imunohistoquímica foi utilizada para identificar receptores de ET1/ET3 e ETA/ETB em valvas mitrais reumáticas e controles. A análise quantitativa da expressão imunohistoquímica para receptores de ET1/ET3 e ETA/ETB foi também efetuada. Adicionalmente, foi feita análise do western blot para mensurar níveis de proteínas em extratos tissulares. Resultados: A expressão imunohistoquímica de ET-1 e de seu receptor predominou em valvas estenóticas, estando associada com regiões fibróticas, áreas inflamatórias e neovascularização. A análise quantitativa mostrou que a área média com expressão positiva para ET-1 foi de 18,21±14,96%. Para o ETA e o ETB, as áreas médias expressas foram, respectivamente, 15,06±13,13% e 9,20±11,09%. ET-3 não teve uma expressão significante. A correlação entre a expressão dos dois receptores de endotelina foi fortemente positiva (R=0,74, P=0,02); mas a correlação entre ET-1 e o seu receptor foi negativa tanto para ETA (R=-0,37, P=0,25) como para ETB (R=-0,14, P=0,39). Estes dados foram confirmados pela análise do western blot. Conclusão: A forte correlação entre ET-1 e seus receptores sugere que ambos têm papel importante na fisiopatologia da estenose mitral reumática, podendo potencialmente atuar como biomarcadores desta doença. .
