Ultrasonography for the diagnosis of tendinitis and electromyography for the diagnosis of peripheral neuropathy and upper limb radiculopathy: rheumatologists' perspectives

OBJECTIVE: To ascertain the value ascribed by Brazilian rheumatologists to ultrasonography (US) for diagnosing tendinitis and to electromyography (EMG) for diagnosing peripheral neuropathy and upper limb radiculopathy. MATERIAL AND METHODS: In total, 165 rheumatologists answered an anonymous survey (sent via the internet) concerning the two exams, with respect to the following characteristics: reliability, diagnostic accuracy, the importance and necessity of these tests for diagnostic RESULTS: The study revealed that most of the rheumatologists recognised that these exams are operator-dependent, that clinicians do not rely entirely on the results, that these exams are not mandatory for the diagnoses listed, and that professionals who perform these exams should be better trained to provide reliable results. CONCLUSIONS: The Brazilian rheumatologists believe the following: the results of these exams should be interpreted with caution and are not definitive for diagnosis; musculoskeletal US and EMG should be performed by trained professionals; and there must be better preparation of the professionals who perform these exams.OBJETIVO: Averiguar o valor que os reumatologistas brasileiros conferem ao exame de ultrassonografia para o diagnóstico de tendinite e ao exame de eletroneuromiografia para o diagnóstico da neuropatia periférica e da radiculopatia dos membros superiores. MATERIAL E MÉTODOS: No total, 165 reumatologistas responderam a uma pesquisa de opinião anônima (enviada pela internet), sobre diversas situações relativas aos dois exames, no que diz respeito aos seguintes questionamentos: confiabilidade, precisão no diagnóstico, importância e necessidade desses exames para confirmação diagnóstica e credibilidade e treinamento dos profissionais que executam os exames. RESULTADOS: O estudo revelou que a maioria dos reumatologistas reconhece que esses exames são operador-dependentes, que não confia integralmente nos resultados observados, que tais exames não são imperativos para os diagnósticos elencados, e que os profissionais que executam esses exames deveriam ser mais bem treinados para fornecer resultados mais confiantes. CONCLUSÃO: Para os reumatologistas brasileiros, os resultados desses exames devem ser interpretados com cautela e não são definitivos para o diagnóstico; a ultrassonografia musculoesquelética e a eletroneuromiografia devem ser realizadas por profissionais capacitados; deve haver melhor preparo dos executores desses exames em nosso meio.Universidade Federal de São Paulo (UNIFESP)Hospital de Base do Distrito Federal Serviço de ReumatologiaUniversidade de BrasíliaJustiça Federal Seção Judiciária de São PauloJustiça Federal do Paraná Seção Judiciária do ParanáUNIFESPSciEL

Door crossing and state identification using robotic vision

This project is aimed at the implementation of an autonomous vehicle guide (AGV) to navigate in internal environments, such as hospitals, offices, residences and so on. The work presents a new 3D algorithm for robotic vision, used for automatic identification of the state of doors, without any previous information about the environment, such as maps, location of obstacles, illumination and the like. The characteristics of the doors that would influence the decision of the robot on the identification of its state, also not ignored, such as texture, color, dimensions. Published in the 8th IFAC International Sysmposium on Robot Control (SYROCO 2006), this work presented the application of the Hougth Transform in images captured by the robotic vision. The coordinates of Hougth then presented the location of the edges of the doors and the analysis of cross-corelation of the found ones, gave us the configuration of the state of the door (open, closed, half open). With the results obtained, the navigation of the autonomous robot became more secure, since the risks of collision were minimized. Navigation using 3D vision, with real-time processing, also reduced the risk of collision with objects dynamically positioned in the environment. In the first part of this document, we present the article published in (SYROCO 2006). In the second part, we present some of the experimental results obtained during the project.O presente relatório técnico trata de um dos projetos realizados no Laboratório de Controle – CONTROLAB do Núcleo de Computação Eletrônica – NCE da Universidade Federal do Rio de Janeiro – UFRJ, nos anos de 2004 e 2005. Este projeto é voltado para a implementação de um robô autônomo AGV (Autonomous Vehicle Guide) para navegar em ambientes internos, tais como hospitais, escritórios, residências e etc. Especializado na área de visão computacional, O trabalho apresenta um novo algoritmo 3D para visão robótica, utilizado para identificação automática do estado de portas, sem quaisquer informações prévias sobre o ambiente, tais como mapas, localização de obstáculos, iluminação e etc. As próprias características das portas que influenciariam na decisão do robô sobre a identificação de seu estado, também não ignoradas, tais como textura, cor, dimensões. Publicado no 8th IFAC International Sysmposium on Robot Control (SYROCO 2006), o trabalho apresentou a aplicação da Transformada de Hougth em imagens capturada pela visão robótica. As coordenadas de Hougth apresentavam então a localização das arestas das portas e a análise de corelação cruzada das quinas encontradas, nos davam a configuração do estado da porta (aberta, fechada, entre-aberta). Com os resultados obtidos, a navegação do robô autônomo se tornava mais segura, vez que os riscos de colisão eram minimizados. A navegação utilizando visão 3D, com processamento em tempo real, também reduzia o risco de colisão com objetos dinamicamente posicionados no ambiente. Na primeira parte deste documento, apresentamos o artigo publicado em (SYROCO 2006). Na segunda parte, apresentamos alguns dos resultados experimentais obtidos durante a realização do projeto

PERFORMANCE OF SOCCER PLAYERS OF DIFFERENT PLAYING POSITIONS AND NACIONALITIES IN A 30-METER SPRINT TEST

The purpose of this study was to compare the performance of soccer players of different playing positions and different nationalities on a 30-meter sprint test. The players were instructed to run at full speed. Tests were performed on a Soccer field. The mean speed for 10 (V10), 10-30 (V20) and 30m (V30) were determined. The results of 75 Brazilian players of different positions were compared between themselves and 21 first division professional Brazilian players were compared with 18 J-League Japanese players. No difference was found between the performances of Brazilian players of different positions. The performance of Brazilian players in V20 and V30 (8.69 ± 0.64 and 7.68 ± 0.28m•s-1) was better than that of Japanese players (8.11 ± 0.26 and 7.42 ± 0.22m•s-1;

A ten-year retrospective study of the clinical, sociodemographic, and survival characteristics of patients with oral and pharyngeal squamous cell carcinomas/ Estudo retrospectivo de dez anos das características clínicas, sociodemográficas e de sobrevida de pacientes com carcinomas epidermóides orais e faríngeos

Objective: This study evaluated the epidemiological profile of patients diagnosed with squamous cell carcinoma, as well compared oral and pharyngeal lesions regarding the survival of these patients. Material and Methods: Convenience sampling was employed to select the participants, who had their medical records of the period 200-2009 investigated. Sociodemographic and clinical-pathological data were collected and correlated with site of the lesion, TMN classification, of the tumor, and survival of the patients. Fisher’s and Chi-square tests, Kaplan-Meir curve associated with the Long Rank Mantel-Cox test, and Cox’s regression for survival analysis were performed to evaluate the results. Results: Sixty-year-old illiterate females presented higher prevalence of oral cancer with a more severe lymphonodular infiltration, worse tumor staging, and chemo and radiotherapy treatment. Meanwhile, sixty-year-old illiterate males presented higher prevalence of pharyngeal cancer, lower rates of lymphonodular infiltration, and chirurgical treatment. The survival of the patients with oral cancer was correlated with the lymphonodular infiltration level, while for patients with pharyngeal cancer the survival was correlated with chirurgical treatment. Thus, head and neck cancer are still diagnosed belatedly, mainly when it affects the pharynx.Conclusion: Therefore, preventive and educative strategies, as well as amplification of access to health care should be considered targets for achieving reduction in the mortality rates of populations with oropharyngeal cancer

Diagnosis and management of Guillain-Barré syndrome in ten steps

Guillain-Barré syndrome (GBS) is a rare, but potentially fatal, immune-mediated disease of the peripheral nerves and nerve roots that is usually triggered by infections. The incidence of GBS can therefore increase during outbreaks of infectious diseases, as was seen during the Zika virus epidemics in 2013 in French Polynesia and 2015 in Latin America. Diagnosis and management of GBS can be complicated as its clinical presentation and disease course are heterogeneous, and no international clinical guidelines are currently available. To support clinicians, especially in the context of an outbreak, we have developed a globally applicable guideline for the diagnosis and management of GBS. The guideline is based on current literature and expert consensus, and has a ten-step structure to facilitate its use in clinical practice. We first provide an introduction to the diagnostic criteria, clinical variants and differential diagnoses of GBS. The ten steps then cover early recognition and diagnosis of GBS, admission to the intensive care unit, treatment indication and selection, monitoring and treatment of disease progression, prediction of clinical course and outcome, and management of complications and sequelae
