Em nível local, há poucos estudos clínicos descritivos sobre manifestações clínicas, otimização de métodos e critérios diagnósticos e sobre o perfil de comorbidade segundo a etiopatogênese (estrutural, funcional, alérgica ou infecciosa). Objetivo: descrever comparativamente os achados clínicos, do transporte mucociliar, citopatológicos, do teste cutâneo para alérgenos, endoscópicos e imaginológicos. Casuística e métodos: 212 casos recrutados dentre 2549 pacientes atendidos no Hospital da Polícia Militar e no Centro de Otorrinolaringológico, em Vitória, ES, entre 3 de janeiro de 2005 e 11 de maio de 2006; 10 tabagistas e 10 não tabagistas sem queixas rinossinusais foram adicionalmente recrutados para comparação. Os achados foram sumarizados como freqüências absoluta e relativa simples de acordo com o grupo etiopatogênico. Resultados: anormalidade estrutural foi identificada em 10 (4,7%), funcional em 11 (5,2%), alérgica em 28 (13,2%), infecciosa em 13 (6,1%), mais de uma das precedentes em 136 (64,1%) e outras doenças em 14 (6,6%). Dentre as 612 comparações analisadas, 19% mostraram freqüência com incremento direto maior que 20% entre os grupos: rinossinusite, rinite alérgica, anormalidade anatômica e funcional. Conclusão: estes resultados demonstram que a comorbidade é a regra e os achados, similares e sobrepostos entre as várias rinossinusopatias, demandam, para a sua distinção, a consideração concomitante dos aportes da história clínica, citopatologia, transporte mucociliar, endoscopia nasal e imaginologia. / Rhinosinusal illnesses are associated with a great morbidity, high costs for the patients and high tax of labor and school absenteeism. Even though these illnesses are well known, there is few descriptive studies about the clinical manifestations, the optimization of the diagnostic criteria and the distribution of comorbidity according to the etiopathogenic types (structural, functional, allergic and infectious) at a local level. Objective: to carry through a comparative description of the clinical, mucociliary clearance, citopathologic, endoscopic and imaginologic findings of the rhinosinusal illness at local doctors office. Patients and methods: 232 of a universe of 2549 patients taken care at two otorrhinolaringologic clinics at Vitória citty, Espírito Santo State, Brazil, from January, 3rd of 2005 to May, 11th of 2006. Of 232, 212 were patients with some rhinosinusal complaints and 20 citizens without rhinosinusal complaints (10 smokers and 10 nonsmokers) were used as control group. The absolute and relative frequency of clinical and laboratory findings were compared between the ethiopathogenic types of rhinosinusal illness. Results: structural abnormalities was present in 10 (4,7%), functional abnormalities in 11 (5,2%), allergy in 28 (13,2%) and infection in 13 (6,1%); in 136 (64,1%) there is more than one of these conditions. Among the 612 findings analised, 19% shows direct increment of frequency higher than 20% between the rhinosinusal types: rhinosinusitis, allergic rhinitis, structural and functional abnormalities. Conclusion: these results show that comorbidity is high and that there is great overlapping of findings between the various types of rhinosinusal illness. To discriminate between them is necessary to take account of concommitant contribution of the clinical history, cytopathology, mucociliary clearance, endoscopic and imaginologic findings.

Optical imaging methods incorporating observation of the mucosal surface of organs with narrowband filtered light are diagnostic tools with a significant development in recent years and have become an integral and inseparable part of the diagnostic process of benign and malignant pathologies of the mucosal surface of various anatomical systems of the human body. Malignant and premalignant lesions of the upper aero-digestive tract (UADT) are no exception. The present work demonstrates the benefits of evaluation of changes in microvascular architecture by narrowband imaging. Its major advantage is a more accurate diagnosis of premalignant and malignant mucosal pathologies in the head and neck region based on the identification of significant changes in superficial vascularity. There is a very strong correlation of these vascular changes with the final histopathological analysis. The present data have shown that videoendoscopic examination with narrowband imaging significantly improves the distinction between benign and malignant mucosal lesions even in the UADT pathologies with a similar tendency to neoangiogenesis (squamous cell papilloma vs. squamous cell carcinoma). It also refines the determination of surface extension of tumoral changes and helps to localize and accurately diagnose tumors of...

This thesis deals with sporting massage and its effects to the human body. There are used some of diagnostic methods verifies the effects of sporting back massage on a muscular function, a skin appearance, physiological functions of the organism and a subjective feeling of a relaxation. For example, there are methods such as a static and a dynamic examination of a spine or an oximeter and a caliper measurements compared to subjective feelings of relaxation in the back area. The methods were applied before and after the experiment, which was based on the series of sporting back massages. The results of the research are compared with other studies and speak in favor for the sporting massage as an effective means of regenerating for the human body as expected on the beginning of the research. The thesis can be used as an available information source for students of sports disciplines and the physically active public, and it can motivate them to include sporting massage into an everyday regeneration processes.

No presente trabalho propomos uma estrutura bayesiana, através de um esquema de dados aumentados, para analisar modelos longitudinais com grupos mútiplos (MLGMTRI) na Teoria da Resposta ao Item (TRI). Tal estrutura consiste na tríade : modelagem, métodos de estimação e métodos de diagnóstico para a classe de MLGMTRI. Na parte de modelagem, explorou-se as estruturas multivariada e multinível, com o intuito de representar a hierarquia existente em dados longitudinais com grupos múltiplos. Esta abordagem permite considerar várias classes de submodelos como: modelos de grupos múltiplos e modelos longitudinais de um único grupo. Estudamos alguns aspectos positivos e negativos de cada uma das supracitadas abordagens. A modelagem multivariada permite representar de forma direta estruturas de dependência, além de possibilitar que várias delas sejam facilmente incorporadas no processo de estimação. Isso permite considerar, por exemplo, uma matriz não estruturada e assim, obter indícios da forma mais apropriada para a estrutura de dependência. Por outro lado, a modelagem multinível propicia uma interpretação mais direta, obtenção de condicionais completas univariadas, fácil inclusão de informações adicionais, incorporação de fontes de dependência intra e entre unidades amostrais, dentre outras. Com relação aos métodos de estimação, desenvolvemos um procedimento baseado nas simulações de Monte Carlo via cadeias de Markov (MCMC). Mostramos que as distribuições condicionais completas possuem forma analítica conhecida e, além disso, são fáceis de se amostrar. Tal abordagem, apesar de demandar grande esforço computacional, contorna diversos problemas encontrados em outros procedimentos como: limitação no número de grupos envolvidos, quantidade de condições de avaliação, escolha de estruturas de dependência, assimetria dos traços latentes, imputação de dados, dentre outras. Além disso, através da metodologia MCMC, desenvolvemos uma estrutura de seleção de matrizes de covariâncias, através de um esquema de Monte Carlo via Cadeias de Markov de Saltos Reversíveis (RJMCMC). Estudos de simulação indicam que o modelo, o método de estimação e o método de seleção produzem resultados bastante satisfatórios. Também, robustez à escolha de prioris e valores iniciais foi observada. Os métodos de estimação desenvolvidos podem ser estendidos para diversas situações de interesse de um modo bem direto. Algumas das técnicas de diagnóstico estudadas permitem avaliar a qualidade do ajuste do modelo de um modo global. Outras medidas fornecem indícios de violação de suposições específicas, como ausência de normalidade para os traços latentes. Tal metodologia fornece meios concretos de se avaliar a qualidade do instrumento de medida (prova, questionário etc). Finalmente, a análise de um conjunto de dados real, utilizando-se alguns dos modelos abordados no presente trabalho, ilustra o potencial da tríade desenvolvida além de indicar um ganho na utilização dos modelos longitudinais da TRI na análise de ensaios educacionais com medidas repetidas em deterimento a suposição de independência. / In this work we proposed a bayesian framework, by using an augmented data scheme, to analyze longitudinal multiple groups models (LMGMIRT) in the Item Response Theory (IRT). Such framework consists in the following set : modelling, estimation methods and diagnostic tools to the LMGMIRT. Concerning the modelling, we exploited multivariate and multilevel structures in order to represent the hierarchical nature of the longitudinal multiple groupos model. This approach allows to consider several submodels such that: multiple groups and longitudinal one group models. We studied some positive and negative aspects of both above mentioned approches. The multivariate modelling allows to represent, in a straightforward way, many dependence structures. Furthermore it possibilities that many of them can be easily considered in the estimation process. This allows, for example, to consider an unstructured covariance matrix and, then, it allows to obtain information about the most appropritate dependece structure. On the other hand, the multilevel modelling permits to obtain: more straightforward interpretations of the model, the construction of univariate full conditional distributions, an easy way to include auxiliary information, the incorporation of within and between subjects (groups) sources of variability, among others. Concerning the estimation methods, we developed a procedure based on Monte Carlo Markov Chain (MCMC) simulation. We showed that the full conditional distributions are known and easy to sample from. Even though such approach demands a considerable amount of time it circumvents many problems such that: limitation in the number of groups that can be considered, the limitation in the number of instants of observation, the choice of covariance matrices, latent trait asymmetry, data imputation, among others. Furthermore, within the MCMC metodology, we developed a procedure to select covariance matrices, by using the so called Reversible Jump MCMC (RJMCMC). Simulation studies show that the model, the estimation method and the model selection procedure produce reasonable results. Also, the studies indicate that the developed metodology presents robustness concerning prior choice and different initial values choice. It is possible to extent the developed estimation methods to other situations in a straightforward way. Some diagnostics techniques that were studied allow to assess the model fit, in a global sense. Others techniques give directions toward the departing from some specific assumptions as the latent trait normality. Such methodology also provides ways to assess the quality of the test or questionaire used to measure the latent traits. Finally, by analyzing a real data set, using some of the models that were developed, it was possible to verify the potential of the methodology considered in this work. Furthermore, the results of this analysis indicate advantages in using longitudinal IRT models to model educational repeated measurement data instead of to assume independence.
