Comparative study between radiological and surgical findings of chronic otitis media
INTRODUCTION: The chronic otitis media (COM) is a prevalent disease and the most frequent cause of indication to mastoidectomy. Many studies have evaluated the use of tomography (CT) of temporal bones for preoperative evaluation of COM and its indication in the preoperative approach is still controversial nowadays. OBJECTIVE: To evaluate the sensitivity of the clinical and radiological findings of COM according to the intraoperative surgical results and histopathological findings. METHOD: Transversal retrospective study through collection of record data of patients with COM submitted to mastoidectomy in the period from 2007 through 2008 in our service. RESULTS: From a total of 82 ears, 40.24% had cholesteatoma. The CT presented 72.73% of sensitivity in the identification of cholesteatoma, 56.67% in the identification of changes to the ossicular chain and 100% in that of erosion of the lateral semicircular canal. CONCLUSION: The clinical and radiological findings showed a high level sensitivity with intraoperative findings as regards to the presence of cholesteatoma, large changes of the ossicular chain and erosion of the lateral semicircular canal. For minor changes to the ossicular chain, the facial nerve canal and the tympanic tegmen they described low sensitivity.INTRODUÇÃO: A otite média crônica (OMC) é uma doença prevalente, e trata-se da causa mais frequente de indicação de mastoidectomia. Muitos estudos têm avaliado a utilização da tomografia (TC) de ossos temporais na avaliação pré-operatória da OMC e sua indicação no pré-operatório ainda permanece controversa nos dias atuais. OBJETIVO: Avaliar a sensibilidade dos achados clínicos e radiológicos de OMC de acordo com os resultados cirúrgicos intra-operatórios e achados histopatológicos. MÉTODO: Estudo retrospectivo transversal através de coleta de dados de prontuários de pacientes com OMC submetidos a mastoidectomia no período de 2007 a 2008 em nosso serviço. RESULTADOS: Em um total de 82 orelhas, 40,24% apresentavam colesteatoma. A TC apresentou 72,73% de sensibilidade na identificação do colesteatoma, 56,67% na identificação de alterações da cadeia ossicular e 100% na de erosão do canal semicircular lateral. CONCLUSÃO: Os achados clínicos e radiológicos mostraram boa sensibilidade com os achados intra-operatórios com relação à presença de colesteatoma, grandes alterações da cadeia ossicular e erosão do canal semicircular lateral. Já para alterações menores da cadeia ossicular, do canal do nervo facial e do tegmem timpânico apresentaram baixa sensibilidade.UNIFESPfaculdade de medicina do ABCHospital Estadual de DiademaUNIFESPSciEL
Intralesional corticosteroid injections in the treatment of central giant cell lesions of the jaws: a meta-analytic study

Results: Sample of 41 patients primarily treated with intralesional corticosteroid injections was obtained, with a
male female ratio of 1:0.95, being 23 aggressive and 18 non-aggressive central giant cell lesions. Triamcinolone
acetonide and triamcinolone hexacetonide were the drugs used, and 78.0% cases were considered as good result,
14.6% were considered as moderate response and 7.3% were considered as negative result to treatment. Consider

Normal Values Determination for High Resolution Esophageal Manometry Using Sitting Viscous Solution Swallows. Results of a Multicenter Study in Healthy Volunteers
Q1Q1Introduction: It has been suggested that a more physiologic esophageal manometry study
protocol, including non-liquid solutions and a sitting position, could improve the test
performance. For the specificity determination of putative findings it is necessary to determine
normal values Aim: To determine normal values for sitting viscous solution swallows in
healthy volunteers using high-resolution esophageal manometry.https://orcid.org/0000-0002-9219-4548Revista Nacional - Indexad

Estudo de Acessibilidade e Interação Multitouch com utilizadores seniores
Dissertação de Mestrado em Design e Multimédia apresentada à Faculdade de Ciências e Tecnologia da Universidade de CoimbraO envelhecimento da Sociedade é uma realidade eminente, essa situação deve- se à
melhoria das políticas públicas e ao aumento de pesquisas multidisciplinares através
de novos medicamentos ou implementação de tecnologias assistivas. Esse aumento
populacional proporciona um campo fértil para estudos que investigam a relação do
publico sênior com o computador, sejam eles relacionadas a interação com aplicações
baseadas em G.U.I (Graphical User Interfaces), ou as mais em voga como as T.U.I
(Tangible User Interfaces). Numa altura em que observa-se a massificação de novas
aplicações com interfaces de toque e gesto, é relevante questionar se estas apresentam
um diferencial positivo para a acessibilidade da população sênior ou são mais um artefato
info excludente. O objetivo deste trabalho é apresentar os resultados das potencialidades
e limitações de interfaces de toque e gesto, através da proposição de heurísticas de
usabilidade para este público. As seis heurísticas propostas foram refutadas e calibradas
por meio de um protótipo de jogo para Ipad., baseado na atividade da vindima.The ageing of Society is an eminent reality, due to the improvement of public
policies and the increasing of multidisciplinary research through new medicines or
implementation of assistive technologies.This increase in population provides a fertile
field for studies investigating the relationship of the senior public with computers,
whether related to the interaction with applications based in G.U.I (Graphical User
Interfaces), or those more popular as T.U.I (Tangible User Interfaces). At a time when
there is the widespread use of new applications with touch and gesture interfaces, it
is important to question whether these have a positive differential to the accessibility
of the senior population or whether they are one more excluding info artifact. The
objective of this project is to present the results of the potentialities and limitations of
touch and gesture interfaces, by proposing usability heuristics for this audience. The
six proposed heuristics were refuted and calibrated by means of a prototype game for
Ipad,based on the activity of Vindima

Functional Morphology of the Crop and Proventriculus of Sitophilus zeamais (Coleoptera: Curculionidae)
Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) is one of the most aggressive pests of stored grains, causing significant decrease in the nutritional quality of the grains and major losses in economic trade. The ability of this pest to damage grains and other products is directly related to the morphology of the alimentary canal. Considering the importance of the foregut in the digestion, this study aimed to describe the morphology of the crop and proventriculus in S. zeamais adults. The tissues were isolated, processed, and analyzed by using light microscopy, scanning electron microscopy, and transmission electron microscopy. The crop functioned as a storage organ, and its cells showed functional characteristics related to protein synthesis. High densities of prokaryotic microorganisms and spicules were found in the lumen. The proventriculus exhibited eight chitinous teeth, which were responsible for grinding and filtering food particles. This organ formed the stomodeal valve, which controlled the unidirectional flow of food through the alimentary canal. The alimentary canal is the primary surface of contact between the external environment and an insect's internal environment, and knowledge of its morphology is required to better understand the physiology of stored-grain insect pests.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
