Representación social de las Técnicas de Reproducción Asistida
Romero Márquez,NR;
Revista de la Facultad de Medicina , 2002,
Abstract: this article constitutes part of a wider work over the social representation of the techniques of atended reproduction, where it states as problem the social representation of the reason to undergo the technique of fertilization in vitro, if it is necessary, in deloberate sample of 50 venezuelan professionals, of both sexes, concurrent to "suma" bookstore located in caracas, during january-april 1990. it was an exploratory-descriptive-interpretative research in which a structured interview was used applying a form of 39 question. only two question are analyzed. the methodology was fundamentally content?s analysis. answers were contained in four levels: a) right to have children, b) selection of son?s sex, c) to have descendants, d) elder?s protection. there are answers similar to those obtained by sadner that stand out values, beliefs, attitudes and fixed social stereotypes. we consider that scarce information exist on the technique and the motivation of a couple should be studied from the psico-social-cultural point of view before subjecting it to this procedure,as well as to inform through the media and legal and psychological and bioethics aspects involved.
Representación social de las Técnicas de Reproducción Asistida

Revista de la Facultad de Medicina , 2002,
Abstract: Este artículo constituye parte de un trabajo más amplio sobre La Representación Social de las Técnicas de Reproducción Asistida; se plantea como Problema la Representación Social de las razones para someterse a la Técnica de Fertilización in Vitro, de resultar necesario, en una muestra intencionada de 50 profesionales venezolanos, de ambos sexos, concurrentes a la librería Suma situada en Caracas, durante enero-abril de 1990. Fue una investigación exploratoria-descriptiva-interpretativa en la cual se utilizó una entrevista estructurada aplicando un formulario de 39 preguntas. Aquí sólo se analizan dos preguntas. La metodología fue fundamentalmente de Análisis de Contenido. Las respuestas fueron agrupadas en cuatro subcategorías: a) Derecho de tener hijos, b) selección del sexo del hijo, c), Tener descendencia, d) Protección en la vejez. Hay respuestas que resultan similares a las obtenidas por Sadner que resaltan valores, creencias, actitudes y estereotipos sociales arraigados. Consideramos que existe poca información sobre la técnica y que deben estudiarse las motivaciones de una pareja desde el punto de vista psico-socio-cultural antes de someterla a este procedimiento; así como informar por los medios de comunicación de todos los aspectos psicológicos sociales, legales y bioéticos involucrados.

Uveítis por tuberculosis en el hospital Universitario de Caracas durante el periodo 2003 - 2004
M Martínez,K Márquez,E Stangogiannis,B Romero
Revista de la Facultad de Medicina , 2004,
Abstract: La uveítis se define como una inflamación del tracto uveal. La infección por el Mycobacterium tuberculosis suele ser secundaria a diseminación hematógena del bacilo de Koch desde un foco primario de infección hasta el globo ocular, o como una reacción de hipersensibilidad celular a diversos componentes antigénicos de la propia micobacteria. Se presenta la revisión de 7 casos clínicos de pacientes que consultaron por la emergencia del HUC presentando disminución de la AV, ojo rojo, dolor ocular, precipitados queráticos, alteración de la PIO en dos de los pacientes, tyndall y solo un caso con compromiso del segmento posterior. Todos los pacientes fueron evaluados por un equipo multidisciplinario incluyendo el Servicio de Neumonología y oftalmología recibiendo tratamiento por cada servicio. Considerando la alta prevalencia de la tuberculosis pulmonar y extrapulmonar en nuestra población, es importante considerar la posibilidad diagnostica de Tuberculosis ocular en aquellos casos de uveítis anterior crónica con nódulos, o bien, en casos de corioretinitis. Uveitis is broadly defined as inflammation of the uvea tract. The infection by the tuberculosis Micobacterium, in addition, processes that may only secondarily of an hematogenous dissemination of the Koch bacillus, from the primary focus of the infection until the ocular globe, or as an reaction of cellular hypersensitivity to different Ag. Components from the same microbacteria. This revision presents seven clinics cases of patients that consult to the emergency of Hospital Universitario de Caracas, because they has diminution of the visual acuty, redness, pain, keratic precipitates, in two cases alteration of the IOP, tyndall and one case the had posterior segment involvement. All the patients had been evaluated with an multidiscipline team included the Neumonology and ophthalmology service received treatment by each service. Considered the prevalence of the pulmonary tuberculoses and extra pulmonary in own poblations, is important to consider the possibility to diagnostic the ocular tuberculosis in those cases of chronic anterior uveitís with nodule, or in cases of chorioretinitis.

Linfocito T? y su papel en la enfermedad periodontal: Revisión de la literatura
Burgos,Angélica; de ávila,Juliette; Márquez,Jaime; Castellanos,Jaime; Lafaurie,Gloria; Romero,Maria Consuelo;
Acta Odontológica Venezolana , 2008,
Abstract: in general is accepted that the innate or adaptive immunity affect the local immune response including the periodontium and in the progression of the disease is critical determinate the nature of the inflammatory response produced by the subgingival bacterial challenge. there are controversies in the literature about the role of t lymphocytes in the periodontal disease, the nature and regulation of these cells can be associated to protective o destructive conditions, but today is not clear the inflammatory or anti-inflammatory events where the cellular immune response by t cells can be absent o deficient during the course of periodontal infection. in fact the opinions about this subject are divided: some of these indicate that the main function of this cells is to protect the host against the periodontal bacteria while another had demonstrated that them participate in the beginning and progression of periodontal disease, for this reason this reviews pretend to discuss their participation in the pathogenesis of this pathology and to know the protective and destructive mechanisms relate with the destruction of periodontal tissue, this is important because they let us to understand new ways for the treatment of this disease.
Disfunción eréctil en pacientes intervenidos de cáncer de próstata: Revisión sistemática de la literatura médica

Abstract: objective: to assess erectile dysfunction in patients with prostate cancer undergoing surgery by radical prostatectomy, laparoscopic prostatectomy or robotic prostatectomy. material and methods: systematic review of literature based on a search strategy (2000-10) in medline, embase, cochrane library, crd, ecri, and hayes. mesh terms used were "prostatectomy", "prostatic neoplasm", "transuretral resection prostate", "impotence" and as free terms "erectile dysfunction" and "prostatectomy". studies included patients with prostate cancer underwent by prostatectomy radical with open surgery (retropubic), laparoscopic or robotic surgery. results: ten observational studies with moderate quality and 29 case series with low quality were selected. observational studies showed lower percentages of erectile dysfunction after intervention in the patients underwent robotic surgery (3-51%). radical surgery (36-91%) and laparoscopic surgery showed higher values of impotence. in the studies that compared surgery versus radiotherapy, the results were better for radiotherapy (3-72% erectile dysfunction). in the case series, lower percentages of erectile dysfunction were shown in patients underwent to robotic surgery (22%), the following was for laparoscopic surgery (40%) and open radical prostatectomy (41.4%). conclusions: this result should be considered with caution because of the low methodological quality of the studies included. however, the different surgical techniques assessed showed similar effects in the two types of studies included and we found that robotic surgery presented lower percentages of sexual impotence.

Abstract: Following the transfer matrix approach, we compute the exact solution for the one-dimensional Ising model with interactions up to third neighbours. We write the result in a compact form, and we show that it coincides with earlier numerical computations. Utilizando el formalismo de la matriz de transferencia, se determina la solución exacta para el modelo de Ising unidimensional con interacción a terceros vecinos. Es obtenida una expresión para el resultado en forma compacta y mostramos que coincide con resultados numéricos anteriores.
