Abstract: Objetivo: Revisar los casos nuevos de cáncer mamario atendidos durante el a o 2003 en la Clínica San Pedro Claver, Bogotá, Colombia. Material y métodos: La captación de las pacientes se hizo a través de la junta de seno, actividad a la cual asisten todas las pacientes nuevas de este servicio. Además, para garantizar la inclusión de la totalidad de ellas, se realizó búsqueda activa de los casos entre las pacientes hospitalizadas, consulta externa, registros de programación de cirugía y reportes de patología. Los datos se registraron en un archivo Excel y evaluaron mediante el programa EPIINFO. Resultados: Se encontraron 207 casos de cáncer mamario. La edad promedio fue 58 a os, 30% tenía menos de 50 a os. El carcinoma ductal infiltrante con el 86,5% de los casos fue el tipo histológico más frecuente. La distribución según los estadios concentró el mayor número de pacientes en los estados 0 al II (61%). Los tumores midieron más de 2 cm (52%). El tratamiento quirúrgico se realizó en 82% de los pacientes. Conclusiones: El Registro Institucional de Cáncer de la Clínica San Pedro Claver permite conocer la distribución de los diferentes tumores en esta entidad prestadora de servicios de salud. El cáncer mamario es la patología neoplásica más frecuente; esta información permite establecer las características personales, clínicas y modalidades terapéuticas pertenecientes a estos pacientes. La mayoría de los casos corresponde a estados tempranos. Sin embargo, se debe continuar en el empe o de detectar un mayor número de lesiones no palpables. Objective. To review the new cases of breast cancer presenting at Clínica San Pedro Claver, Bogotá, Colombia, in the year 2003. Material and methods. Recruitment of patientsfor this study was trough the Breast Conference, an activity that is attended by all new patients in our service.

Abstract: objective: reviewing new cases of breast cancer attending clinica san pedro claver, bogotá, colombia, during 2004. material and methods: patients were recruited from the meeting offered by the service which all new breast cancer patients attend. hospitalised patients, outpatients, clinical meetings, consulting rooms, operating room schedules and pathology reports were consulted to ensure that a true cross-section was included. the information was recorded in an excel file and analysed using epiinfo software. results: breast cancer was diagnosed in 220 patients. average age was 59; 18 % were aged les than 40. infiltrative ductal cancer (84,1 %) was the most frequently found histological type. distribution by stage showed that most patients presented stage 0 to stage ii (62,7 %). tumours measured 2 or more centimetres in 78 % of the patients. 83 % of the patients had surgery and 60 % chemotherapy. however, these scores were lower in patients aged more than 69 (58,3 % for surgery and just 13,9 % for chemotherapy, p<0.05). hormonotherapy was prescribed for 40,9 % of the patients. conclutions: breast cancer is the more frequent found carcinoma. clinica san pedro claver's cancer records revealed the personal, clinical and therapeutic characteristics of new female breast cancer patients attending this hospital during 2004. most patients were in early breast cancer stages; however, detecting a greater number of non-palpable lesions should still be stressed. treating elderly patients (those older than 69 regarding that found for younger patients) and the quality of procedures, hormonal receptor reports and therapeutic decision should also be evaluated in an attempt to explain the low percentage of hormone treatment currently being used in the hospital.

Abstract: introduction. in colombia the impact of infections of trypanosoma cruzi are known to produce chronic cardiopathy and expressed by bradycardia. in colombia the extent and impact of these infections has not been examined. objective. the current study aimed to determine the prevalence of t. cruzi infection as measured by serology, in a population of patients with cardiopathy that required a permanent pacemaker as treatment for cardiac rhythm abnormalities and conduction blocking. materials and methods. a cross sectional study sampled 332 patients from the pacemaker clinic at the san pedro claver hospital in bogotá, colombia, for one year (2004-2005). epidemiological and clinical data were obtained through interviews and physical examination. serological tests consisted of indirect inmunofluorescence assay and elisa. statistical analyses were accomplished with chi-square and students? t tests. results. of patients with pacemakers, 17.1% had anti-t. cruzi antibodies (seropositive). at the time when the pacemaker was implanted, chronic chagas? disease patients were younger (55±13 years) than those patients with cardiopathy (60±17 years) with no anti-t. cruzi antibodies (p<0.01). the seropositive group was aware of the chagas? disease vector (83.6%) in contrast to the seronegative group (39.6%, p<0.001). in 60% of the patients of the seropositive group, no clinical signs of the disease were apparent. the geographical origin of the seropositive group were traced to regions in colombia known to be endemic for chagas′ disease transmission. conclusion. chagas′ disease prevalence is high in colombian patients who required a permanent cardiac pacemaker. chronic chagas? disease patients required pacemaker implant at a younger age in contrast with patients with other cardiac pathologies. the clinical recognition of chagas′ disease associated with cardiopathy is low despite the epidemiological data.

Abstract: Introducción. En Colombia no se conoce cuál es el impacto de la infección por Trypanosoma cruzi en la producción de cardiopatía crónica expresada por bradiarritmias graves que requierenimplante de marcapaso. Objetivo. Determinar la seroprevalencia de anticuerposanti-Trypanosoma cruzi en pacientescon bloqueos de conducción o disfunción sinusal que requirieron implantación de marcapaso. Materiales y métodos. Mediante un estudio descriptivo de corte transversal (2004-2005) en 332 pacientes de la consulta de marcapaso de la clínica San Pedro Claver de Bogotá, se estimó la seroprevalencia de anticuerpos anti-Trypanosoma cruzi mediante las pruebas de inmunofluorescencia indirecta y ELISA. Se aplicó un formulario de recolección de datos epidemiológicos y de hallazgos de examen físico. El análisis estadístico se hizo mediante las pruebas de ji al cuadrado y T de Student. Resultados. La seroprevalencia anti-T. cruzi fue de 17,11%. Esta seropositividad se asoció con: menor edad al momento del implante del marcapaso (55,22+13,62 Vs. 59,82+17,19, p=0,0013), con el reconocimiento de los triatominos (83,6% Vs. 39,6%, p<0,001) y con haber vivido antes de los 15 a os en zonas endémicas para la enfermedad de Chagas. El paciente no conocía el diagnóstico de enfermedad de Chagas o éste no se sospechó clínicamente en el 60% de los casos. Conclusiones. La prevalencia de anticuerpos anti-T. cruzi en pacientes portadores de marcapaso es alta. La implantación de marcapasos se presentó más tempranamente en el grupo seropositivo. No hay adecuada sospecha clínica ni información al paciente sobre el diagnóstico de la enfermedad de Chagas. Introduction.

Abstract: En este art culo revisamos el trabajo realizado para medir la turbulencia atmosf erica al nivel del suelo en el Observatorio Astron omico Nacional en San Pedro M artir. Arguimos, basados en resultados m as modernos obtenidos a lo largo de m as de una d ecada, que la mediana de la calidad de imagen es de 0.55 segundos de arco a una altura de 15m. Este an alisis comprueba que San Pedro M artir es uno de los mejores sitios del mundo en cuanto a calidad de imagen y probablemente el mejor.

Revista mexicana de astronomía y astrofísica , 2003,
Abstract: The Observatorio Astron omico Nacional is run and operated by the Instituto de Astronom a of the National Autonomous University of Mexico. It is located in the northern part of M exico, in the sierra San Pedro M artir (SPM), in the state of Baja California. At an altitude of 2890 m above sea level, 31 north in latitude, anked by the Paci c Ocean and the gulf of Baja California, SPM has proven to be one of the last pristine spots for a ground-based astronomical observatory in our planet. The IAUNAM is making substantial e orts towards conservation and further development of this excellent astronomical site. Here we present a brief account of its basic characteristics and facilities.

Physics , 2003,
Abstract: We analyze the monthly average wind velocity at about 12 km above sea level, between 1980 to 1995, for San Pedro Martir, Mauna Kea, another existing observatorie and some sites of interest. We compare the results obtained from two different data sets, the GGUAS and NCEP. Our results show that San Pedro Martir and Mauna Kea are comparable and are amongst the most suitable sites to apply slow wavefront corrugation correction techniques
