Estudo da função da tuba de eustáquio em pacientes com retrações da membrana timpânica e em indivíduos normais / Assessment of eustachian tube function in patients with tympanic membrane retraction and in normal subjects

Canali, Inesângela January 2013 (has links)
Introdução: O diagnóstico das disfunções da tuba auditiva é essencial para o melhor entendimento da patogênese da otite média crônica. Estão descritos, na literatura, uma série de testes que avaliam a função tubária, entretanto, entre eles, há uma diversidade metodológica que varia desde os protocolos de aplicação até a padronização dos testes e seus resultados. Objetivo: Avaliar a variação da pressão na orelha média em pacientes com retração da membrana timpânica e em indivíduos normais, durante a realização dos testes de função tubária, bem como avaliar a variação intraindividual desses testes. Este estudo também tem por objetivo avaliar o número de movimentações da membrana timpânica na orelha contralateral, durante a realização dos testes. Métodos: Estudo observacional do tipo transversal e contemporâneo, onde o fator em estudo foi a variação de pressão na orelha média, durante a realização dos testes de função tubária (Manobra de Valsalva, Sniff Test, Manobra de Toynbee) em indivíduos normais e em pacientes com retrações timpânicas leves e moderadas/severas. Foram incluídos 38 pacientes, totalizando 76 orelhas. Os pacientes foram submetidos, em dois momentos diferentes, aos testes de função tubária para determinar a medida da pressão após cada manobra. Durante a realização dos testes, videotoscopia era realizada concomitantemente na outra orelha, a fim de se observar a movimentação da membrana timpânica. A análise estatística foi realizada por meio do programa SPSS versão 18.0, em que foram considerados como estatisticamente significativos os valores de p< 0,05. Resultados: A média ± desvio-padrão da idade foi de 11 ± 2,72 anos; 55,3% dos pacientes foram do sexo masculino e 44,7% do sexo feminino. A prevalência de curva A foi maior nos grupos de orelhas normais e retrações leves, enquanto que de curva C foi maior no grupo de retrações moderadas/severas. Observamos aumento das pressões na orelha média durante a realização da Manobra de Valsalva no primeiro momento de avaliação nos três grupos de orelhas (p= 0,012). A variação da pressão não foi significativa nem para o Sniff Test, nem para o Toynbee nos dois momentos de avaliação (p≥0,05). A concordância das medidas nos dois diferentes momentos foi de fraca a moderada para os testes nos três grupos de orelhas, e as variâncias da discrepância entre as medidas foram maiores nas orelhas com retrações moderadas/severas. Apesar de não ter atingido significância estatística, o número de movimentações da membrana timpânica foi maior durante a manobra de Valsalva nos três grupos de orelhas. Conclusão: Na população estudada, a média das pressões na cavidade timpânica apresentou uma variação significativa somente durante a Manobra de Valsalva, no primeiro momento de avaliação, nos três grupos de orelhas. As orelhas normais e as com retração leve se comportaram de forma semelhante entre si em todos os testes. As manobras utilizadas apresentaram uma variação intraindividual de fraca a moderada, sendo que maior variação ocorreu em orelhas com retrações moderadas/severas. O número de movimentações da membrana timpânica foi maior durante a manobra de Valsalva nos três grupos de orelhas. / Introduction: The diagnosis of Eustachian tube dysfunctions is essential for better understanding the pathogenesis of chronic otitis media. The literature describes a series of tests to assess tube function; however, there is methodological diversity between them, which varies from application protocols to standardization of tests and their results. Objective: To evaluate the variation in middle ear pressure in patients with tympanic membrane retraction and in normal subjects during tube function tests, as well as to evaluate intra-individual variation between these tests. This study also aimed to evaluate the number of tympanic membrane movements of the contralateral ear during the tests. Methods: An observational contemporary cross-sectional study was conducted, in which the factor under study was the variation in middle ear pressure during tube function tests (Valsalva maneuver, Sniff Test, Toynbee maneuver) in normal subjects and in patients with mild and moderate/severe tympanic retraction. A total of 38 patients (76 ears) were included in the study. Patients underwent tube function tests at two different time points, in order to determine the measure of pressure after each maneuver. During the tests, videotoscopy was performed concomitantly in the contralateral ear, in order to observe tympanic membrane movement. Statistical analysis was performed using SPSS software, version 18.0, considering p values < 0.05 as statistically significant. Results: Mean ± standard deviation for age was 11 ± 2.72 years; 55.3% of patients were male and 44.7% female. The prevalence of type A tympanogram was higher in the groups with normal ears and mild retraction, while type C tympanogram was higher in the group with moderate/severe retraction. An increase in middle ear pressure was observed during Valsalva maneuver at the first time point evaluated in the three groups of ears (p= 0.012). The variation in pressure was not significant either for the Sniff Test or for Toynbee maneuver at the two time points evaluated (p≥0.05). The agreement of the measures at the two different time points was from weak to moderate for the tests in the tree groups of ears, and the variations in discrepancy between measures were higher in ears with moderate/severe retraction. Although it had not reached statistical significance, the number of tympanic membrane movements was higher during the Valsalva maneuver in the tree groups of ears. Conclusion: In this study population, mean pressure in the middle ear showed a significant variation only during the Valsalva maneuver at the first time point evaluated in the three groups of ears. Normal ears and those with mild retraction behaved similarly in all tests. The maneuvers used showed intra-individual variation from weak to moderate, with the higher variation occurring in ears with moderate/severe retraction. The number of tympanic membrane movements was higher during the Valsalva maneuver in the three groups of ears.

Avaliação da qualidade de vida e função pulmonar nos pacientes com câncer de pulmão

Müller, Alice Mânica January 2011 (has links)
Base Teórica: O câncer de pulmão é uma doença muito prevalente e altamente fatal. A maioria dos pacientes diagnosticados já se encontra em estágio avançado da doença. Mas existem recursos que contribuem para melhorar a sobrevida destes pacientes, e é necessário avaliar o quão esta doença interfere na qualidade de vida dos mesmos, bem como, na sua funcionalidade. Objetivos: Avaliar a qualidade de vida e função pulmonar de pacientes com câncer de pulmão do Hospital de Clínicas de Porto Alegre que realizaram cirurgia e/ou quimioradioterapia. Métodos: Foi realizado um estudo de coorte, prospectivo, observacional. Foram incluídos no estudo 92 pacientes ambulatoriais/internações com diagnóstico de câncer de pulmão recém diagnosticados e que ainda não tinham iniciado tratamento. Foram submetidos a uma avaliação da QV através do SF-36, espirometria e TC6’ antes de iniciar o tratamento, após 60 dias e 120 dias do início do mesmo. Resultados: No presente estudo, predominou adenocarcinoma e estádio avançado da doença, 27 pacientes cirúrgicos e 60 não cirúrgicos. Não houve diferença na QV entre os 3 momentos, mas um aumento significativo da CVF% nos primeiros 60 dias. Houve correlação significativa entre VEF1 e aspectos físicos e capacidade funcional nos dois grupos, e distância e vitalidade nos não cirúrgicos. A sobrevida foi de 50% nos primeiros 12 meses. Pacientes cirúrgicos tem maior probabilidade de sobrevida do que os não cirúrgicos. Conclusões: Nossos resultados mostraram que pacientes com câncer de pulmão, cirúrgicos e não-cirúrgicos, obtiveram correlações positivas entre VEF1(%) e qualidade de vida em ambos os grupos, assim como, distância da caminhada com vitalidade no grupo não cirúrgico. / Background: Lung cancer is a disease very prevalent and highly fatal. Most patients are already diagnosed with late-stage disease. But there are resources that contribute to improving patient survival, and is necessary to evaluate how this disease affects quality of life of these patients, as well as in its functionality. Objectives: To assess the quality of life and lung function of patients with lung cancer of the “Hospital de Clinicas” of Porto Alegre that underwent surgery and / or chemo-radiotherapy. Methods: We conducted a cohort study, prospective, observational. The study included 92 outpatients / admissions diagnosed with lung cancer at diagnosis and who had not yet started treatment, to undergo assessment of QOL using the SF-36, spirometry and 6MWT before starting treatment, after 60 days and 120 days of start date. Results: It predominated adenocarcinoma and advanced stages disease; totals of 27 surgical and 60 nonsurgical patients. There was no difference in QOL between the three moments, but a significant increase in FVC% in the first 60 days. There was significant correlation between FEV1 and the physical and functional capacity in both groups, and distance and vitality in nonsurgical group. As such, higher chances of survival of surgical patients than nonsurgical. Survival decreased 50% in the first 12 months. Conclusions: Our results demonstrated that patients with lung cancer, surgical and nonsurgical, have obtained positive correlations between FEV1(%) and quality of life in both groups, as well as with walking distance and vitality in nonsurgical group.

Preclinical ventricular function analysis and myocardial tissue characterisation using MRI at 4.7 T

Firth, Matthew Steven January 2016 (has links)
This thesis describes the development of MRI techniques for identifying disease within cardiac muscle of the rodent heart at 4.7 T. The new methods allow measurement of myocardial T1 and T2* relaxation times and ventricular volumes from cine images. Before in-vivo application, each MRI pulse sequence and imaging protocol was tested using tissue representative phantoms on a cardiac motion simulator. A multi-slice cardiac cine pulse sequence was developed for measuring cardiac volumes that used a modified slice acquisition order compared to standard cine MRI to extend TR and thereby increase the signal without extending the total scan time. This acquisition method was compared to a slower conventional cine pulse sequence by measuring the signal to noise ratio and the left ventricular mass and volumes of the mouse heart. T1 values are known to increase in hearts affected by dilated and hypertrophic cardiomyopathy, so pulse sequences were developed for measuring myocardial relaxation values. In-vivo T1 measurements were made using saturation and inversion recovery pulse sequences. Comparison of the results showed that the inversion recovery pulse sequence gave results that were more consistent with published values from similar studies so it was concluded that this should be used for future cardiomyopathy investigations. A study was carried out on an in-vivo control group to test the effectiveness of the superparamagnetic contrast agent Ferumoxytol in enhancing T2* differences between healthy and pathological tissues. It was found that Ferumoxytol did not affect the T2* of the healthy myocardium and this result was confirmed by histology which revealed very little Ferumoxytol uptake in the heart but plentiful uptake in the liver. The results of this study indicate that future investigations in rats with induced cardiomyopathy can assume that changes in myocardial relaxation times are due to the effects of cardiac disease rather than the contrast agent.
