Introduction & Background: Here I describe the current trends and future per-spectives of PACS implementation and research in the rapidly evolving European scenario. In fact, in the recent years a wealth of experience has been gathered both from the clinical and the research points of view in many countries, including those of Central and Eastern Europe. Topics of relevant interest include the development of regional PAC systems with inno-vating networking strategies and the progressive con-vergence between PACS and tele-radiology. The pur-chase of PACS services is no longer limited to tradi-tional approaches, as ASP is emerging as a possible alternative attractive to both vendors and hospital managers. Another important aspect is the increasing role of standards in supporting filmless hospitals: in this domain, Integrating the Health Enterprise - Europe (IHE-E) promises to allow functionally driven system integration. Finally, there is an increasing in-terest towards the E-learning applications that use PACS systems as tools for fostering education in radiology.Date

SECUELAS POST-INFECCION POR ADENOVIRUS EN NIÑOS: EVALUACION CON TOMOGRAFIA COMPUTADAJosé D. Arce V; Roberto Mondaca A; Rodolfo Mardones R; Luis F Velozo P; Genoveva Parra O (Publimpacto, 2002-01-01): Introducción. La infección pulmonar por adenovirus en el niño, puede presentar una amplia variedad de manifestaciones clínicas, y ser causa de hospitalizaciones prolongadas. Como complicaciones pueden ocurrir la muerte o el desarrollo de graves secuelas pulmonares. El diagnóstico se plantea sobre la base de los antecedentes clínicos y se confirma con estudio de inmunofluorescencia en secreción faríngea. Los estudios de imágenes son importantes en el diagnóstico y control de la evolución de la enfermedad fundamentalmente la radiografía (Rx) de tórax y la tomografía computada (TC). Objetivo. Presentar nuestra experiencia con el uso de TC en niños que presentaron infección por adenovirus, con énfasis en las secuelas. Se destaca además la relación de la enfermedad con la existencia de la un tipo genómico viral (7h). Pacientes y método. Se revisó retrospectivamente 24 TC de 23 niños en quienes se demostró infección por adenovirus, en el periodo agudo, a través de inmunofluorescencia indirecta en muestra de secreción faríngea y en quienes se descartó otras patologías pulmonares. Resultados. En todos los pacientes la TC mostró alteraciones compatibles con bronquiolitis obliterante y los hallazgos principales correspondieron a atrapamiento aéreo (23 pacientes, 24 TC) que fue difuso o multifocal dando un patrón de atenuación en mosaico; engrosamiento peribronquial y disminución del diámetro y cantidad de los vasos en el área comprometida (23 pacientes, 24 TC), bronquiectasias (15 pacientes, 16 TC). El compromiso pulmonar fue bilateral en todos los pacientes. En un número importante de casos se encontró atelectasia cicatrizal (19 pacientes; 20 TC) con colapso pulmonar. En 3 de ellos se resecó el segmento pulmonar colapsado y el estudio histológico demostró bronquiolitis constrictiva. Pensamos que esta manifestación es resultado de una mayor agresividad del tipo genómico de adenovirus predominante en nuestro país. Conclusiones. La TC de tórax fue de utilidad en la evaluación y determinación de las secuelas pulmonares de pacientes con antecedentes de neumopatía por adenovirus y mostró hallazgos compatibles con bronquiolitis obliterante en todos los casos de nuestra serie. Destaca la relación de esta infección con un tipo genómico viral (7h), prevalente en el área sur de Sudamérica<br>: Introduction. Severe pulmonary involvement may occur after adenovirus infection and longstanding pulmonary sequelae may observe essentially bronchiolitis obliterans (BO). Objective. To evaluate the CT findings in children who had suffered adenovirus infection. Patients and method. We reviewed retrospectively the CT findings in 23 children with proven adenovirus infection, excluding those patients with other pulmonary diseases. Results. In all patients CT showed findings consistent with bronchiolitis obliterans, characterized by diffuse or multifocal air trapping with a secondary mosaic attenuation (23 patients), peribronchial thickening and decreased vascularization in the involved areas (23 patients), bronchiectasis (23 patients) and segmental atelectasis (19 patients). In 3 patients the collapsed lobe was resected and histology showed BO. Conclusions. CT was helpful in the study of patients who had suffered adenoviruses infection and showed findings consistent with BO in all of them. This infection could be related with a greater predominance of genome type 7h in South American countries. The amount of pulmonary collapse could be related with the more aggressive serotype of adenovirus in our country

Educação a distância mediada pela internet: "Linfonodo sentinela, prevenção, diagnóstico precoce e biópsia - nova técnica de abordagem do câncer de mama" Internet-conducted distance education: "Sentinel lymph node, prevention, early diagnosis and biopsy - a new technique for approaching breast cancer"Santuzza Kelmer; Afrânio Coelho-Oliveira; Lea Mirian Barbosa da Fonseca (Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, 2007-08-01)OBJETIVO: O objetivo deste estudo é o desenvolvimento e a aplicação de um curso na modalidade "Educação a distância mediada pela internet". MATERIAIS E MÉTODOS: Foi utilizado o curso "Linfonodo sentinela, prevenção, diagnóstico precoce e biópsia - nova técnica de abordagem do câncer de mama" como modelo de aplicação. O material didático para a modalidade "Educação a distância" foi elaborado visando a um público composto por médicos envolvidos com o tratamento do câncer de mama. O curso foi estruturado em ambiente virtual de aprendizagem, um espaço virtual que permitiu a interação entre os participantes. RESULTADOS: A duração do curso foi de 12 semanas. Iniciou-se com nove participantes, médicos ginecologistas com pelo menos oito anos de experiência profissional. Todos os alunos participaram de alguma forma, dois realizaram exercícios e interagiram. O alcance do curso pelo método atingiu quatro estados e oito municípios. Não ocorreu adesão integral dos alunos, apesar de a maioria permanecer até o fim do curso. Possivelmente, não houve motivação suficiente para participação nas atividades propostas. CONCLUSÃO: Os resultados mostram que é necessário quebrar as barreiras da falta de cultura relacionada a esta forma de aprendizagem. É fundamental a participação facilitadora do coordenador para integração e mobilização dos participantes.<br>OBJECTIVE: The present study was aimed at developing and delivering a course in the modality "Internet-conducted distance education". MATERIALS AND METHODS: The theme "Sentinel lymph node, prevention, early diagnosis and biopsy - a new technique for approaching breast cancer" was utilized as an application model, and the didactic material for distance-learning was targeted to a selected audience of physicians involved in the treatment of breast cancer. The course was structured in a virtual learning environment, allowing interaction among participating students. RESULTS: The coursework took place over a 12-week period. Nine gynecologists with at least eight years of professional experience participated in some way in the course, but only two of them accomplished exercises and interacted. In the distance-education modality, the course reached eight cities in four Brazilian states. A full engagement did not occur, although most of participants have remained until the end of the course. Possibly, there was a lack of motivation. CONCLUSION: The results demonstrate that it is necessary to break the barriers to the culture related to this form of learning. A pro-active participation of the coordinator is essential for integrating and mobilizing the participants.

Clases pasivas, clases activas y clases virtuales: ¿Transmitir o construir conocimientos?Ricardo Luis Videla (Sociedad Argentina de Radiología, 2010-06-01)Para realizar el proceso de enseñanza-aprendizaje existen múltiples estrategias pedagógicas. En las clases pasivas se transmiten conocimientos y el centro de la clase es el maestro y sus saberes. En las clases activas y en el Aprendizaje Basado en Problemas (ABP) se pretende que los estudiantes descubran y construyan el conocimiento. En el ABP el problema precede al aprendizaje. Las clases virtuales y el blended learning (clases pasivas y virtuales) funcionan en el fondo también como transmisión del conocimiento. En el presente trabajo se revisan las fortalezas y debilidades de estas distintas modalidades de enseñanza-aprendizaje.<br>Passive, active and virtual classes. Transmitting or constructing knowledge? Many teaching strategies have been developed to achieve the teaching-learning process. In passive classes knowledge is transmitted and the class is centered in the teacher and his/her knowledge. In active classes and problem-based learning (PBL) the intention is to get students to discover and construct knowledge. In PBL the problem precedes learning. Virtual classes and blended learning (passive and virtual classes) also in the end function as a transfer of knowledge. This paper reviews the strengths and weaknesses of these different teaching and learning modalities.
