[Rare location of arachnoid cysts. Extratemporal cysts]. / Quistes aracnoideos de localización infrecuente. Quistes extratemporales.

The therapeutic management of arachnoid cysts depends largely on its location. Almost 50% of arachnoid cysts are located in the temporal fossa-Sylvian fissure, whereas the other half is distributed in different locations, sometimes exceptional. Under the name of infrequent location arachnoid cysts, a description is presented of those composed of 2 sheets of arachnoid membrane, which are not located in the temporal fossa, and are primary or congenital.

[Intraventricular schwannoma of the choroid plexus. Case report and review of the literature]. / Schwannoma intraventricular del plexo coroideo. Descripción de un caso y revisión de la bibliografía.

INTRODUCTION: Intraventricular tumors account for approximately 10% of central nervous system tumors. The intraventricular schwannomas are rare because there are only 15 cases reported in the international literature. CASE REPORT: A forty-one years old female, with a history of migraines during 17 years, consulted for headaches and nausea. Brain computed tomography and magnetic resonance imaging evidenced solid nodular lesion at the right occipital horn with homogeneous contrast enhancement. Complete excision was performed through a right parietal craneotomy and a transcortical approach. The postoperative evolution was favorable. The pathology report: schwannoma. The magnetic resonance imaging 18 months after resection showed no recurrence of tumors. CONCLUSION: Intraventricular schwannomas are very rare tumors. Surgery is treatment of choice for total resection. This is a diagnosis to consider in intraventricular tumors.

Profile of practitioners of supervised physical exercise in the southern region of Brazil / Perfil dos praticantes de exercício físico supervisionado da região sul do Brasil

With 23,398 fitness academies, catering for around seven million users, Brazil ranks second behind the United States in the number of units. The objective of this study is to delineate the profile of supervised physical activity practitioners in the three most southern states of Brazil (Paraná, Santa Catarina, and Rio Grande do Sul), analyzing the reasons which lead them to choose a fitness service. Fitness academy clients were also surveyed in relation to their alcohol, tobacco and food supplement usage. Seven hundred and ninety-seven (797) people were evaluated by means of a questionnaire. Data was collected in 24 fitness academies (eight in each state) in the three most southern states of Brazil. It was observed that those who practiced exercise regularly at fitness academies smoked little, consumed few food supplements, and with (50.44%) of those surveyed stating that they consumed only moderate amounts of alcohol. The majority, (34.13%) of exercise practitioners in southern Brazil chose to go to the gym five times a week, (40.99%) went at night, with (40.56%) giving as their reason for practicing exercise as being a way to improve their health. The distance between their home and the gym was the most important reason in choosing a place to conduct training. Intense individual activities were the most practiced type of exercise, there being no statistical difference between the percentages in the three states.

O Brasil ocupa o segundo lugar do mundo em número de academias, totalizando 23.398 unidades com cerca de sete milhões de frequentadores, ficando atrás apenas dos EUA. Neste sentido, o objetivo desse estudo foi delinear o perfil dos praticantes de atividade física supervisionada, analisando os motivos que os levam a escolher um serviço de fitness, bem como traçar o perfil de consumo de álcool, tabaco e suplementos alimentares dos habitantes da Região Sul do Brasil. Foram avaliadas 797 pessoas através de um questionário próprio. A coleta foi realizada em 24 academias divididas em oito para cada um dos três estados do Sul do Brasil. Observou-se que os frequentadores de academias da área de abrangência da pesquisa fumam pouco, consomem poucos suplementos alimentares e apenas 50,44% dessa população consome bebidas alcoólicas de maneira moderada. A maior parte (34,13%) dos praticantes de exercício físico do Sul do Brasil optam por frequentar a academia cinco vezes por semana, no período noturno (40,99%), com o intuito de melhorar a saúde (40,56%). A distância entre a residência e a academia se mostrou o motivo mais relevante para escolher um locar para realizar o treinamento. O tipo de exercício mais praticado são as atividades individuais mais intensas e não houve diferença estatística entre os percentuais nos três estados estudados.

Quistes aracnoideos de localización infrecuente. Quistes extratemporales / Rare location of arachnoid cysts. Extratemporal cysts

El manejo terapéutico de los quistes aracnoideos depende, en gran medida, de su localización. Casi el 50% de los quistes aracnoideos se localizan en la fosa temporal-cisura de Silvio. En cambio, la otra mitad se reparte en localizaciones diversas, a veces excepcionales. En este trabajo describimos, bajo la denominación de «quistes aracnoideos de localización infrecuente», aquellos compuestos por las 2 hojas de membrana aracnoidea que no se encuentran localizados en la fosa temporal y que son primarios o de origen congénito

Schwannoma intraventricular del plexo coroideo. Descripción de un caso y revisión de la bibliografía / Intraventricular schwannoma of the choroid plexus. Case report and review of the literature

Introducción: Los tumores intraventriculares representan alrededor del 10% de los tumores del sistema nervioso central. Los schwannomas intraventriculares son infrecuentes y solo existen 15 casos descritos en la literatura. Caso clínico Paciente de 41 años de edad, con antecedentes de migrañas de 17 años de evolución, que consultó por cefaleas y náuseas. La tomografía y resonancia magnética de cerebro evidenciaron una lesión nodular sólida a nivel del asta occipital derecha con realce homogéneo con contraste. Se realizó una exéresis completa a través de una craneotomía parietal y un abordaje transcortical. La evolución postoperatoria fue favorable. La anatomía patológica informó: schwannoma. La resonancia de control a los 18 meses no mostró recidiva. Conclusión Los schwannomas intraventriculares son lesiones muy infrecuentes. El tratamiento quirúrgico de elección es la resección completa. Es un diagnóstico a tener en cuenta en tumores intraventriculares (AU)
