Abstract Background Hypertension is an increasingly common problem in adolescents; amongst the associated factors, physical inactivity and obesity are increasing the risk of developing cardiovascular diseases. Objective To verify whether there is an association between higher blood pressure levels amongst adolescents with the relationship between different levels of body mass index (BMI) and cardiorespiratory fitness (CRF). Method Cross-sectional study consisting of 860 adolescents. Higher blood pressure (BP) was considered as borderline and hypertension as the classification. BMI was categorized as low-normal weight and overweight-obesity. The CRF was assessed by a nine-minute run/walk test and classified into low or appropriate levels (less and more favorable to health, respectively). Later, BMI and CRF were grouped into one categorical variable: (I) low/normal weight and appropriate CRF levels; (II) low/normal weight and low CRF levels; (III) overweight/obesity and appropriate CRF levels; and (IV) overweight/obesity and low CRF levels. Data were analyzed using Poisson regression, through the prevalence ratio (PR) and 95% confidence intervals (CI). The p-values of p <0.05 were considered significant. Results Adolescents with overweight/obesity and low CRF levels had a 22% higher BP prevalence. Moreover, children with overweight/obesity, but with appropriate CRF levels, have a 15% higher BP prevalence. Conclusion Adolescents with overweight/obesity had a higher prevalence of BP, regardless of CRF levels. It is suggested that maintaining normal BMI is a protective factor for less favorable BP. factors diseases (BMI CRF. .

RESUMO Objetivo: Determinar a especificidade, sensibilidade, acurácia, razão de verossimilhança e correlação dos achados dos testes meniscais e da ressonância magnética (RM) com a videoartroscopia do joelho. Métodos: Estudo transversal feito entre junho e dezembro de 2015. Avaliaram-se 84 pacientes selecionados para tratamento videoartroscópico das lesões meniscais (LM). Dois ortopedistas especializados em cirurgia do joelho e um residente em ortopedia fizeram o exame físico com testes específicos. Os resultados obtidos e laudos da RM foram comparados com os achados da videoartroscopia. Os dados foram tratados no programa estatísticoR. Resultados: O teste de Steinmann I, foi mais específico, com especificidade de 86% e 91% para lesões de menisco medial (LMM) e lesões de menisco lateral (LML), respectivamente. Quanto à acurácia, o teste de dor à palpação da interlinha articular (DPIA) apresentou valores de 67% e 73% para detecção de LMM e LML, respectivamente. O teste de DPIA apresentou maior sensibilidade, com 77% de chance de detectar LMM. A análise do conjunto de três testes (McMurray, DPIA e Steinmann I, ) comparada com a videoartroscopia apresentou 85% de sensibilidade para as LMM e 70% de sensibilidade para as LML. A RM apresentou maior especificidade para o diagnóstico de LMM e LML; 82% e 91%, respectivamente.. Conclusão: O conjunto dos três testes apresentou melhores resultados se comparado com os testes isolados e pode ser associado à RM para elaboração de um diagnóstico efetivo. Entretanto, são necessários outros estudos que auxiliem na elaboração de um protocolo para padronizar a avaliação diagnóstica.

ABSTRACT Objective: To determine the specificity, sensitivity, accuracy, likelihood, and correlation of the findings of meniscal tests and magnetic resonance imaging (MRI) to knee video arthroscopy., Methods: A cross-sectional study, conducted between June and December 2015, which evaluated 84 patients with meniscal tears (MT) selected for video arthroscopy. Two orthopedic trainees and a resident performed a physical examination with specific tests. The results and reports from MRI were compared with arthroscopy findings. The data were analyzed in the statistical program , R. Results: The Steinmann I, test was the most specific, with specificity of 86% and 91% for medial meniscus tears (MMT) and lateral meniscus tears (LMT), respectively. With regard to accuracy, the pain test on palpation of the joint interline (PPJI) showed values of 67% and 73% for detection of MMT and LMT, respectively. The PPJI test showed higher sensitivity, with a 77% chance of detecting MMT. Analysis of the set of three tests (McMurray, PPJI, and Steinmann , I, ) compared to arthroscopy showed 85% sensitivity for MMT and 70% sensitivity for LMT. MRI showed a greater specificity for the diagnosis of MMT and LMT; the values were 82% and 91%, respectively. Conclusion: The combination of the three tests shows better results compared to the isolated tests and thus can be associated to the MRI to make an effective diagnosis. However, further studies assisting in the development of a protocol to standardize diagnostic evaluation are required.

RESUMO OBJETIVOS: Avaliar clinica e radiologicamente os resultados do tratamento videoartroscópico com uso de âncoras metálicas em pacientes com luxação recidivante de ombro e suas complicações. MÉTODOS: Estudo retrospectivo de 47 pacientes (47 ombros) operados de fevereiro de 2010 a fevereiro de 2012 pelo grupo do ombro do hospital ortopédico, por meio de questionário, entrevista, exame físico e radiográfico, com o uso da classificação de Samilson e Pietro. O seguimento médio no pós-operatório foi de 33 meses (variação de 12-47). A análise estatística consistiu no uso do teste exato de Fisher por meio do pacote estatístico IBM SPSS 22, com o uso de um nível de significância de 5%. RESULTADOS: Recidiva foi observada em nove casos. Os pacientes tinham, em média, 26,5 anos no primeiro episódio, dos quais 19,1% apresentavam idade menor ou igual a 20 anos. Dentre estes, 55,6% apresentaram recidiva. Em relação à idade no procedimento cirúrgico, foi encontrada uma média de 27 anos; 12,8% apresentavam idade menor do que ou igual a 20 anos; 19 pacientes apresentaram âncoras salientes e desses 21% manifestavam artrose. CONCLUSÃO: Houve correlação estatisticamente identificada entre o índice de recidiva e a idade menor ou igual a 20 anos no momento da primo-luxação e do procedimento cirúrgico. Mais estudos devem ser feitos para comparar uso de âncoras absorvíveis, que, apesar de ter um custo mais elevado, podem ter um risco menor de desenvolvimento de artrose glenoumeral em alguns casos.

ABSTRACT OBJECTIVE: To clinically and radiologically evaluate the results from videoarthroscopic treatment using metal anchors in patients with recurrent shoulder dislocation and its complications. METHODS: This was a retrospective study on 47 patients (47 shoulders) operated by the shoulder group of the orthopedic hospital between February 2010 and February 2012. A questionnaire, interview and physical and radiographic examinations were used, with the classification of Samilson and Pietro. The mean postoperative follow-up was 33 months (range 12-47 months). The statistical analysis consisted of using Fisher's exact test through the IBM SPSS 22 statistical software. The significance level used was 5%. RESULTS: Recurrence was observed in nine cases. The patients were, on average, 26.5 years old at the first episode, and 19.1% were aged 20 years or under. Among these, 55.6% presented recurrence. In relation to age at the time of the surgical procedure, the average age was 27 years, and 12.8% were aged 20 years or under. Nineteen patients presented prominent anchors and, of these, 21% manifested arthrosis. CONCLUSION: There was a statistically identified correlation between the recurrence rate and age less than or equal to 20 years at the times of first dislocation and the surgical procedure. Further studies should be conducted in order to compare the use of absorbable anchors, which despite higher cost, may provide lower risk of developing glenohumeral arthrosis in some cases.

OBJETIVO: Verificar o conhecimento e as atitudes sobre epilepsia na população de Caxias do Sul. MÉTODO: Foi aplicado um questionário sobre familiaridade com a doença, conhecimentos e atitudes diante de um portador de epilepsia a 832 moradores da cidade. As respostas foram analisadas em três grupos distintos: G1, não-universitários; G2, universitários até o segundo ano; e G3, universitários com mais de dois anos e graduados. RESULTADOS: Os universitários e graduados possuem melhor conhecimento sobre causas e tratamento da epilepsia. Além disso, esses entrevistados apresentam menos atitudes negativas para com o portador de epilepsia. Entretanto, uma boa parte desse grupo apresenta falta de alguns conhecimentos básicos sobre a doença. CONCLUSÃO: Há falta de informação à população brasileira sobre epilepsia. Campanhas educacionais devem ser realizadas no intuito de desmistificar alguns aspectos concernentes à epilepsia.

OBJECTIVE: To verify awareness and attitudes toward epilepsy in Southern Brazil. METHOD: A questionnaire about familiarity with the disease, awareness and attitudes toward epileptics was applied to 832 inhabitants of Caxias do Sul. The answers were analyzed in three different groups: G1, non-university students; G2, university students up to the second year; and G3, university students with more than two years education and university graduates. RESULTS: University students and graduates are better informed regarding causes and treatment of epilepsy. Moreover, those interviewees present less negative attitudes toward epileptics. However, a large part of that group lacks some basic information on the disease. CONCLUSION: There is lack of information on epilepsy among Brazilians. Education campaigns should be carried out in order to clarify some aspects concerning epilepsy.
