Publicación Sólo datos Caracterización de casos de dengue y dengue hemorrágico, Villavicencio, Meta 2002(Universidad de los Llanos, 2005-01-01) APONTE GARZÓN, L.HTitulo en ingles:Characterization of cases of fastidiousness and fastidiousness it hemorrhages, Villavicencio, Meta 2002.RESUMEN: Con el propósito de caracterizar los casos de dengue y dengue hemorrágico reportados a la Secretaría Local de Salud por las diferentes Instituciones Prestadoras de Salud durante el año 2002 (n = 732), se hizo un estudio de tipo descriptivo retrospectivo. En el estudio se incluyeron las variables sociodemográficas y clínicas, y dentro de ellas, se midieron las variables diagnósticas, presentación clínica, evolución y pruebas de laboratorio. Se creó una base de datos en EpiInfo 2000 para el manejo estadístico de los datos. Los resultados muestran que la población de casos notificados corresponden principalmente a adultos, hombres y mujeres entre los 20 a 50 años, (µ=26,9, DS = ± 18.1), residentes de zona urbana. Se encuentra que los casos de la zona clasificada como rural corresponden en su mayoría a una zona en donde se encuentran instituciones que mantienen un gran número de personas adultas en áreas limitadas. En el análisis comparativo entre casos de dengue hemorrágico y dengue clásico confirmado se encontró asociación significativa entre la presencia de dengue hemorrágico y manifestaciones hemorrágicas (OR =7.73), y prueba de torniquete positiva (OR =33.95). Al revisar y analizar los datos de hematocrito de cada caso reportado como dengue hemorrágico en esta cohorte se encontró que el 62,5% no presentaban hemoconcentración. La revisión de datos y algunos resultados muestran que existen marcados problemas de registro de datos en su consistencia y correcto diligenciamiento de las fichas de notificación de casos desde las IPS y en el proceso de digitación de datos en el Programa de Prevención y Control de Dengue. Se hacen recomendaciones de construcción de ficha de notificación y proceso de recolección de datos de manera que se mejore la calidad del dato construido y se incremente la disponibilidad de datos confiables para la vigilancia en salud pública, intervenciones comunitarias e iniciativas de investigación.Palabras claves: Dengue, dengue hemorrágico, epidemiología, enfermedades tropicales.ABSTRACT: With the purpose of characterizing all dengue and dengue hemorrhagic cases a descriptive retrospective study was conducted. The sample included all dengue classic and dengue hemorrhagic cases reported to the Local Secretary of Health by different health services providers during the year 2002 (n = 732). Characterization was made using socio-demographic and clinical variables which included diagnostic, clinical manifestations, case evolution and tests results. A database with all cases was created using EpiInfo 2000.The results show that cases are mainly men and women between 20 to 50 years, (µ=26,9, DS = ± 18.1), residents of urban area. It was found that cases of rural area correspond to an area where there are institutions with an important number of people, mostly young adults located in limited areas. In the comparative analysis between cases of dengue hemorrhagic and confirmed classic dengue, significant associations between the presence of dengue hemorrhagic and hemorrhagic manifestations (OR=7.73), and positive tourniquet test (OR =33.95) were found. More than 62% of all dengue hemorrhagic cases had hematocrit levels different from those that reflects hemoconcentration, or had not data on hematocrit values for reaching any conclusions about hemoconcentration presence. he analysis of data and results pointed out the problems created as a result of lack of notification form completeness, poor consistency in reported data, as well as inaccurate database in the Prevention and Control Dengue Program. Recommendations on data construction, notification form, and data collection were made in order to improve information quality, and reliability, which will increase public health surveillance, and community interventions effectiveness, and research initiatives .Key words: Dengue, dengue hemorrhagic, epidemiology, tropical diseLasesPublicación Sólo datos Preliminary results of in vitro fertilization for the endangered murciano-levantina bovine breed(Universidad de los Llanos, 2004-01-01) Barajas, DP; Velásquez, JG; and Coy P, Poto AASBTRACT: The Murciano-levantina cattle from the Spanish South-East belongs to a bovine endangered breed under the special protection of FAO (WWL-DAD:3)*. Their characteristics of rusticity, longe- vity, docility and disease resistance make interesting the recovery of the breed. The objective of the present work was to deter mine the efficiency of in vitro bovine embryo production using oocytes collected from post mortem ovaries fertilized with frozen thaw sperm obtained either from commercial or Murciano-levantina bulls. Cumulus oocyte complexes were matured for 24 h in TCM199 with 10% FBS, 2mM L-glutamine, 0.2 mM sodium pyruvate, 0.3 µg/mL LH and µg/mL FSH. Oocytes presumed matured were fertilized with Percoll-prepared sper m (750.000/mL) in IVF-TALP as described by Parrish et al. (Biol. Reprod 38:1171-1180, 1988). Zygotes (at 18 h) or two-cell stage embryos (at 48 h) were assessed by staining with Hoechst 33342 (µg/mL; 20 min) under an epifluorescence microscopy. The experiment was replicated on 4 occasions.The results of penetration (PEN-%), average number of spermato- zoa inside the oocyte (S/O), monos permy (MON- %) putative embryos (zygotes with two pronuclei, 2 PN-%) and percentages of cleavage at 48 hours (Table 1) were recorded. The results show that early embryos can be obtained with no difference with the source of sperm used in the monospermy and the cleavage rate between commercial and Mur- ciano-levantina sperm (p>0.05). *Lista Mundial de Vigilancia para la Diversidad de los Animales Do- mésticos (1997). http:// www.fao.org/docrep/V8300S/ V8300S00.htm
