RESUMO

BACKGROUND: Primary Sjögren's syndrome (pSS) is a systemic immune-mediated disease whose main characteristic is exocrine gland inflammation and, subsequent reduction in tear and saliva production. A delayed diagnosis is common due to the nonspecific clinical manifestations of disease. The aim of the present study was to develop recommendations for the diagnosis of glandular manifestations of pSS based on evidence and expert opinion. We conducted a systematic literature review to retrieve the best evidence available on the accuracy of diagnostic tests for pSS. We also held two in-person meetings with experts (rheumatologists, pathologists, ophthalmologists and dentists) to establish their level of agreement using the Delphi method. Ultimately, we generated 18 recommendations that aim to facilitate the diagnosis of the glandular manifestations of pSS. CONCLUSION: The diagnosis of glandular manifestations of pSS is complex and multidisciplinary. It requires specific knowledge in the field of ophthalmology, immunology, pathology and imaging, making it compulsory for the rheumatologist to work with professionals from these different areas in order to improve accuracy and early diagnosis. Glandular dysfunction tests, ANA, RF, Anti-Ro, protein electrophoresis, urinalysis, blood count, C-Reactive protein, complement, testing for syphilis and viruses (HCV, HIV) and SGUS should be investigated when dryness or systemic manifestation are present. Minor salivary gland biopsy is recommended for all anti-Ro negative or incomplete criteria cases.

RESUMO

BACKGROUND: Little is known about the prevalence and impact of risk of malnutrition on short-term mortality among seniors presenting with acute heart failure (AHF) in emergency setting. The objective was to determine the impact of risk of malnutrition on 30-day mortality risk among older patients who attended in Emergency Departments (EDs) for AHF. MATERIAL AND METHODS: We performed a secondary analysis of the OAK-3 Registry including all consecutive patients ≥65 years attending in 16 Spanish EDs for AHF. Risk of malnutrition was defined by the Mini Nutritional Assessment Short Form (MNA-SF) < 12 points. Unadjusted and adjusted logistic regression models were used to assess the association between risk of malnutrition and 30-day mortality. RESULTS: We included 749 patients (mean age: 85 (SD 6); 55.8% females). Risk of malnutrition was observed in 594 (79.3%) patients. The rate of 30-day mortality was 8.8%. After adjusting for MEESSI-AHF risk score clinical categories (model 1) and after adding all variables showing a significantly different distribution among groups (model 2), the risk of malnutrition was an independent factor associated with 30-day mortality (adjusted OR by model 1 = 3.4; 95%CI 1.2-9.7; p = .020 and adjusted OR by model 2 = 3.1; 95%CI 1.1-9.0; p = .033) compared to normal nutritional status. CONCLUSIONS: The risk of malnutrition assessed by the MNA-SF is associated with 30-day mortality in older patients with AHF who were attended in EDs. Routine screening of risk of malnutrition may help emergency physicians in decision-making and establishing a care plan.

RESUMO

OBJECTIVE: to know the epidemiological profile of patients undergoing surgery for well-differentiated thyroid carcinoma at the Cassiano Antônio Moraes University Hospital of the Federal University of Espírito Santo, as well as the oncological results and the main postoperative complications. METHODS: we conducted a cross-sectional, retrospective study of patients with well-differentiated thyroid carcinoma (WDTC) operated from January 2008 to December 2015. RESULTS: During the study period, 95 of the 353 patients undergoing surgical treatment of the thyroid gland had WDTC. Papillary carcinoma was the most frequent (91.57%). Total thyroidectomy not associated with cervical emptying was the most frequent surgical procedure (65.26%). Postoperative complications occurred in 6.31% of patients, hematoma being the most frequent. The mean follow-up time was 36.9 months. Relapse occurred in four patients (4.21%), being locoregional in all cases. The prognostic factors analyzed, such as gender, age, tumor size, lymph node involvement, staging, type of surgery, histology and complementary iodine therapy did not show statistical significance. CONCLUSION: papillary carcinoma was the most common thyroid malignant neoplasm, affecting women in the 49-year-old age group more frequently. Loco-regional recurrence occurred in four patients. Hematoma was the most frequent complication.

RESUMO

RESUMO Objetivo: conhecer o perfil epidemiológico dos pacientes submetidos à cirurgia do carcinoma bem diferenciado da tireoide no Hospital Universitário Cassiano Antônio Moraes da Universidade Federal do Espírito Santo, assim como os resultados oncológicos e as principais complicações pós-operatórias. Métodos: estudo transversal e retrospectivo de pacientes portadores de carcinoma bem diferenciado da tireoide operados no período de janeiro de 2008 a dezembro de 2015. Resultados: no período do estudo, dos 353 pacientes submetidos a tratamento cirúrgico da glândula tireoide, 95 eram portadores de CBDT. O carcinoma papilífero da tireoide foi o mais frequente (91,57%). A tireoidectomia total não associada a esvaziamento cervical foi o procedimento cirúrgico mais frequente (65,26%). As complicações pós-operatórias ocorreram em 6,31% dos pacientes, sendo o hematoma a mais frequente. O tempo médio de seguimento foi de 36,9 meses. A recidiva ocorreu em quatro pacientes (4,21%), sendo locorregional em todos os casos. Os fatores prognósticos analisados, como sexo, idade, tamanho do tumor, acometimento linfonodal, estadiamento, tipo de cirurgia, histologia e iodoterapia complementar não demonstraram significância estatística. Conclusão: o carcinoma papilífero da tireoide foi a neoplasia maligna mais frequente, acometendo o sexo feminino na faixa etária dos 49 anos mais frequentemente. A recidiva locorregional ocorreu em quatro pacientes. O hematoma foi a complicação mais frequente.

RESUMO

RESUMOObjetivo:Fazer a adaptação transcultural do Eular Sjögren's Syndrome Patient Reported Index (ESSPRI) para a língua portuguesa e avaliar as suas propriedades psicométricas.Método:Estudo transversal de pacientes com síndrome de Sjögren primária (SS). Foram estudadas as propriedades psicométricas (reprodutibilidade intraobservador e a validade de construto). Na validade de construto, o ESSPRI foi comparado com o Patient's Global Assessment (PaGA), Profile of Fatigue and Discomfort (Profad), Sicca Symptoms Inventory (SSI) e Functional Assessment of Chronic Illness Therapy (Facit-fatigue). Os testes estatísticos usados foram o α-Cronbach, coeficiente de correlação intraclasse (CCI), método de Bland-Altman e coeficiente de Spearman. Foi considerado significativo o p ≤ 0,05.Resultados:Não houve diferença entre as versões nas duas línguas e obteve-se, assim, a versão consensual brasileira. Todos os indivíduos foram mulheres de 49,4 ± 11,6 anos, com início dos sintomas de 7,2 ± 5,4 anos e tempo de diagnóstico de 3 ± 3,3 anos. A média do ESSPRI foi de 6,87 ± 1,97. A reprodutibilidade intraobservador foi alta e significativa (0,911) e, no método de Bland-Altman, não houve viés sistemático na concordância das medidas entre as avaliações. Houve correlação moderada do ESSPRI com todos os instrumentos testados.Conclusão:A versão do ESSPRI em português é válida e reprodutível.


ABSTRACTObjective:To carry out the cross-cultural adaptation of EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) for Portuguese language and evaluate its psychometric properties.Method:Cross-secal study of patients with primary Sjögren's syndrome (SS). The psychometric properties (intraobserver reproducibility and construct validity) were studied. In construct validity, ESSPRI was compared with the Patient's Global Assessment (PGA), Profile of Fatigue and Discomfort (Profad), Sicca Symptoms Inventory (SSI) and Functional Assessment of Chronic Illness Therapy (Facit-F). Statistical tests used were: Cronbach's alpha, intraclass correlation coefficient (ICC), Bland-Altman method and Spearman coefficient. A value of p ≤ 0.05 was considered significant.Results:There was no difference between versions in both languages; thus, a Brazilian consensual version was obtained. All subjects were women aged 49.4 ± 11.6 years, with onset of symptoms of 7.2 ± 5.4 years, and time of diagnosis of 3.0 ± 3.3 years. The mean ESSPRI was 6.87 ± 1.97. The intraobserver reproducibility was high and significant (0.911) and, with Bland-Altman method, there was no systematic bias in the agreement of measures among evaluations. A moderate correlation of ESSPRI with all tested instruments was observed.Conclusion:The Brazilian Portuguese version of ESSPRI is a valid and reproducible version.

RESUMO

Despite its infrequent occurrence, testicular schistosomiasis forming pseudo-tumors can be considered in the differential diagnosis of testicular tumors, especially in areas where the parasitic disease is endemic. In this report, we present a case of testicular schistosomiasis caused by Schistosoma mansoni and mimicking a testicular neoplasm. We describe the patterns of a testicular nodule on ultrasonography and magnetic resonance images in a 46-year-old man. The nodule was removed after a pre-operative diagnosis of a non-malignant lesion. Histology demonstrated granulomas with epithelioid macrophages and eosinophils around S. mansoni eggs within a fibrous tissue that formed a nodular structure.

RESUMO

BACKGROUND: Diabetic nephropathy (DN) is one of the major causes of end-stage renal disease in diabetic patients. Increasing evidence from studies in the rodents has suggested that this disease is associated with increased oxidative stress due to hyperglycemia. In the present study, we evaluated the renoprotective, anti-oxidative and anti-apoptotic effects of the flavonoid quercetin in C57BL/6J model of DN. METHODS: DN was induced by streptozotocin (STZ, 100 mg/kg/day, for 3 days) in adult C57BL/6J mice. Six weeks later, mice were divided into the following groups: diabetic mice treated with quercetin (DQ, 10 mg/kg/day, 4 weeks), diabetic mice treated with vehicle (DV) or non-treated non-diabetic (ND) mice. RESULTS: Quercetin treatment caused a reduction in polyuria (~45%) and glycemia (~35%), abolished the hypertriglyceridemia and had significant effects on renal function including, decreased proteinuria and high plasma levels of uric acid, urea and creatinine, which were accompanied by beneficial effects on the structural changes of the kidney including glomerulosclerosis. Flow cytometry showed a decrease in oxidative stress and apoptosis in DN mice. CONCLUSION: Taken together, these data show that quercetin effectively attenuated STZ-induced cytotoxicity in renal tissue. This study provides convincing experimental evidence and perspectives on the renoprotective effects of quercetin in diabetic mice and outlines a novel therapeutic strategy for this flavonoid in the treatment of DN.

RESUMO

OBJETIVOS: Determinar o aporte nutricional de iodo na população estudada e correlacionar os níveis de iodo encontrados em amostras casuais de urina (iodúria) com alterações anatomopatológicas observadas nas tireoides dessa população. MATERIAIS E MÉTODOS: Determinou-se a iodúria em 30 amostras casuais de urina e realizou-se o estudo anatomopatológico de 55 tireoides colhidas de cadáveres que deram entrada no Departamento Médico Legal de Vitória, Espírito Santo, Brasil, no período de maio a agosto de 2011. RESULTADOS: Em 29 amostras de urina (96,7%) encontrou-se iodúria acima do limite máximo preconizado pela Organização Mundial da Saúde (OMS) de 300 µg/L. Em 14 tireoides (25,5%) foi identificada a presença de quadros histológicos compatíveis com tireoidite. Níveis mais elevados de iodo na urina foram observados no sexo feminino e nos casos de tireoides com presença de achados inflamatórios (tireoidites). CONCLUSÕES: Podemos concluir que na população estudada houve um excesso de iodo em seu aporte nutricional e uma maior incidência de quadros inflamatórios tireoidianos.


OBJECTIVES: To determine iodine nutrition in the population and to correlate levels of iodine found in random samples of urine with pathological changes observed in thyroids collected in this population. MATERIALS AND METHODS: Urinary iodine was determined in 30 random samples of urine and the pathological study was carried out in 55 thyroid glands from corpses received by the Department of Forensic Medicine of Vitória, Espírito Santo, Brazil from May to August 2011. RESULTS: In 29 urine samples (96.7%) urinary iodine was above the maximum limit recommended by the World Health Organization (WHO), of 300 mg/L. Fourteen thyroids (25.5%) showed the presence of histological changes compatible with thyroiditis. Higher levels of iodine in urine were observed in females and in of thyroid that showed inflammation (thyroiditis). CONCLUSIONS: We conclude that, in this population, there is excess iodine intake, and greater incidence of inflammatory thyroid disease.

RESUMO

The aims of this study were to evaluate the effects of nandrolone (ND) on cardiac inflammatory cytokines, ACE activity, troponin I, and the sensitivity of the Bezold-Jarisch reflex (BJR). Male Wistar rats were administered either ND (20 mg/kg; DECA) or vehicle (control animals; CONT) for 4 weeks. BJR was analyzed by measuring the bradycardia and hypotension responses elicited by serotonin administration (2-32 µg/kg). Mean arterial pressure (MAP) was assessed and myocyte hypertrophy was determined by the heart weight/body weight ratio and by morphometric analysis. Matrix collagen deposition was assessed by histological analysis of the picrosirius red-stained samples. Mesenteric vascular reactivity was performed and central venous pressure (CVP) evaluated. Cardiac inflammatory cytokine levels and angiotensin-converting enzyme (ACE) activity were studied as well the biomarker of cardiac lesion, troponin I. DECA group showed enhancement of matrix type I collagen deposition (p < 0.01) and cardiac ACE activity (p < 0.01) compared with the CONT. Interleukin (IL)-10 was reduced (p < 0.01) and pro-inflammatory cytokines (TNF-α and IL-6; p < 0.01) were increased in the DECA group compared with CONT. Cardiac injury was observed in the DECA group shown by the reduction in cardiac troponin I (p < 0.01) compared with the CONT group. Animals in the DECA group also developed myocyte hypertrophy and reduction of BJR sensitivity. The MAP of animals treated with ND reached hypertensive levels (p < 0.01; compared with CONT). No changes in CVP and vascular reactivity were observed in both experimental groups. We conclude that high doses of ND elicit cardiotoxic effects with cardiac remodelling and injury. Cardiac changes reduce the BJR sensitivity. Together, these abnormalities contributed to the development of hypertension in animals in the DECA group.

RESUMO

The androgen nandrolone decanoate (ND) is known to cause cardiovascular abnormalities, such as attenuation of the Bezold-Jarisch Reflex (BJR), cardiac hypertrophy, and elevation of mean arterial pressure (MAP). Futhermore, a relationship between androgens and the renin-angiotensin system (RAS) has been reported. The purpose of this study was to evaluate the influence of RAS on the BJR, cardiac and prostatic hypertrophy, and MAP evoked by ND. For this, male Wistar rats were treated with ND (10 mg·(kg body mass)(-1) for 8 weeks; DECA), or vehicle (control animals; CON), or enalapril (10 mg·(kg body mass)(-1), daily; CONE), or ND and enalapril (10 mg ND + 10 mg enalapril per kilogram of body mass; DECAE). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotensive responses that were elicited by serotonin administration (2-32 µg·(kg body mass)(-1)). MAP was assessed; cardiac and prostate hypertrophy were determined by the ratio of the tissue mass:body mass, and by histological analysis of the heart. Animals from the DECA group showed prostatic and cardiac hypertrophy, elevation in mean arterial pressure, and an impairment of BJR. Co-treatment with enalapril inhibited these changes. The data from the present study suggest that RAS has an impact on BJR attenuation, cardiac and prostatic hypertrophy, and the elevation in MAP evoked by ND.

RESUMO

We investigated the influence of long-term treatment with supraphysiological doses of an anabolic-androgenic steroid on the Bezold-Jarisch reflex (BJR) control of heart rate (HR) and diastolic arterial pressure (DAP), and whether this treatment induced cardiac hypertrophy. Male rats were treated with nandrolone decanoate (ND) (10 mg kg(-1) body weight for 8 weeks; DECA) or vehicle (control animals; CON). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotension responses that were elicited by serotonin administration (2-32 microg kg(-1)). Mean arterial pressure (MAP) was assessed and cardiac hypertrophy was determined by the ratio of the left and right ventricle weight/body weight (LVW/BW and RVW/BW, respectively) and by histological analysis. Total body protein (TBP) content was also evaluated. Nandrolone decanoate treatment increased MAP (CON=99+/- 1 mmHg; DECA=109+/-2 mmHg; p<0.01) but did not change the mean basal HR (CON=356+/-13 bpm; DECA=367+/-11 bpm). The treatment also induced LV and RV hypertrophy (LVW/BW: CON=1.86+/-0.04 mg g(-1), DECA=2.17+/-0.04 mg g(-1), p<0.01; RVW/BW: CON=0.42+/-0.02 mg g(-1), DECA=0.53+/-0.03 mg g(-1), p<0.05) and reduced the number of myocyte nuclei/high-power field (CON=23.0+/-2; DECA=9.4+/-1.0; p<0.01). ND treatment blunted the HR and DAP decreases induced by serotonin. ND determines an increase in the TBP content in DECA group (35+/-3%; p<0.01) compared with control animals (18+/-1%). We conclude that 8 weeks of ND treatment induces anabolic effect, cardiac hypertrophy and an elevation of MAP. This treatment also reduces the sensitivity of the BJR control of bradycardia and blood pressure, possibly due to cardiac hypertrophy. The blunted BJR response could contribute to the MAP elevation in DECA animals.

RESUMO

Traditional Periodic Acid Schiff has been extensively used, coupled with immunohistochemistry for epithelia or mesenchymal cells, to highlight renal tubular basement membrane (TBM). We recently tried to perform such technique in a 5/6 nephrectomy model of progressive renal fibrosis to demonstrate TBM disruption as an evidence for epithelial-mesenchymal transdifferentiation. Despite excellent basement membrane staining with traditional fuchsin-Periodic Acid Schiff, the interface between epithelial and mesenchymal cells was frequently blurred when revealed with 3'3 diaminobenzidine tetrachloride-peroxidase. Also, it was inadequate when revealed with alkaline phosphatase-fast red. We devised a triple staining method with Periodic Acid-Thionin Schiff to highlight basement membrane in blue, after double immunostaining for epithelium and mesenchymal cells. Blue basement membrane rendered a brisk contrast and highlighted boundaries between epithelial-mesenchymal interfaces. This method was easy to perform and useful to demonstrate the TBM, yield a clear demonstration of the very focal TBM disruption found in this model of progressive renal fibrosis.

RESUMO

BACKGROUND: We investigated the influence of short-term treatment with supraphysiological doses of an anabolic-androgenic steroid on the Bezold-Jarisch reflex (BJR) control of heart rate (HR) and whether this treatment induced cardiac hypertrophy and anabolic effects in rats. METHODS: Male rats were treated with nandrolone decanoate (10 mg/kg(-1) body weight/4 weeks; DECA) or vehicle control (CON). After 4 weeks of treatment, BJR was evaluated by bradycardia responses that were elicited by serotonin administration (2-32 microg/kg(-1)). Mean arterial pressure (MAP) was assessed and cardiac hypertrophy was determined by the left ventricle weight/body weight (LVW/BW) ratio. Histological analyses of LV and the measurement of the total body protein content of the animals were performed. RESULTS: Nandrolone decanoate (ND) treatment had no effect on the MAP (CON=105+/-5; DECA=110+/-3 mmHg). However, the mean basal HR of DECA animals was significantly lower than that of control animals (CON = 381+/-14; DECA=324+/-12 bpm; p<0.01). ND did not change the sensitivity of the BJR. The LVW/BW ratio indicated significant hypertrophy of the LV in DECA animals (CON=1.76+/-0.04; DECA=2.0+/-0.04 mg/g; p<0.01). Histological and morphometrical analyses demonstrate that there is also modest myocyte hypertrophy (CON=14.5+/-1.5; DECA=20.0 +/- 0.9 myocyte nuclei/field; p<0.05). However, the Masson-trichromic-stained samples showed an enhancement of collagen deposits on the LV matrix. CONCLUSIONS: We concluded that 4 weeks ND treatment induced an anabolic effect and the beginnings of LV remodeling, mainly due to excessive collagen deposition in the cardiac extracellular matrix. However, the treatment did not influence BJR control of bradycardia, an effect that could be explained by an enhanced efferent vagal tonus in DECA animals.

RESUMO

Para caracterizar os eventos na fibrose túbulo-intersticial renal, foi realizado estudo em ratos submetidos a nefrectomia 5/6 e tratados com micofenolato mofetil e/ou losartan. Cortes histológicos de rim foram submetidos a processamento histológico e imuno-histoquímico para a identificação e quantificação do colágeno e de vários marcadores de células epiteliais, mesenquimais e inflamatórias. O estudo morfométrico foi realizado utilizando-se imagens digitalizadas e método computadorizado de análise de imagem. Verificou-se redução da deposição de colágeno e da expressão daqueles marcadores celulares, principalmente nos grupos tratados com a associação micofenolato mofetil e losartan / In order to characterize the events of tubulointerstitial fibrosis, it was performed a study in 5/6 ablation rats receiving losartan and/or micophenolate mofetil therapy. Kidney sections were submitted to several histochemical and immunohistochemical procedures. Morphometric evaluation was performed using digitalized image and a computer assisted image analyzer...
