Revista chilena de pediatría , 2005,
Abstract: La extubación fallida (EF) es una de las complicaciones frecuentes en la evolución postoperatoria de los ni os sometidos a cirugía de cardiopatías congénitas (CCC). Las tasas reportadas oscilan entre 6,7% y 22%, siendo pocas las publicaciones que identifican los factores de riesgo para EF. Objetivos: Determinar la tasa de EF después de CCC e identificar posibles factores de riesgo. Pacientes y Métodos: Estudio retrospectivo de ni os < 3 a os sometidos a CCC con circulación extracorpórea (CEC); las variables preoperatorias, del defecto cardíaco, intraoperatorias, del tipo de reparación y postoperatorias fueron recopiladas y analizadas estadísticamente. Resultados: Se estudió un total de 242 ni os sometidos a CCC; la tasa de EF fue 9,9%. Presentaron mayor incidencia de EF los pacientes en los que se usó paro cardíaco hipotérmico profundo (PCHP) (p = 0,0043, OR = 3,1) y aquellos que desarrollaron estridor laríngeo en el postoperatorio (p = 0,0006, OR = 21,6). La presencia de síndrome de Down (p = 0,009, OR = 5,7) y la edad < 6 meses (p = 0,03, OR = 3,7) fueron identificados como factores de riesgo independientes. Los pacientes con EF presentaron tiempos de ventilación mecánica (VM) más prolongados (p = 0,001) y mayor incidencia de neumonía intrahospitalaria. Conclusiones: Cerca de un 10% de los intentos de extubación fallan en pacientes sometidos a CCC con CEC y esta tasa es similar a las reportadas por otros autores. En nuestro estudio los principales factores de riesgo para EF fueron el desarrollo de estridor laríngeo después de la extubación, el uso de PCHP, la presencia de síndrome de Down y la edad < 6 meses. La EF se asoció a mayor duración de la VM y con el desarrollo de neumonía intrahospitalaria Introduction: Extubation failure (EF) is a common complication after congenital heart disease surgery (CHDS), ranging from 6.7% to 22%. There are few publications that identify risk factors associated with EF in these patients. Objective: To determine the rate of EF after CHDS and identify risk factors. Method: A 3 years retrospective chart review of children less than 3 years-old who underwent CHDS with cardiopulmonary bypass (CPB). Preoperative, operative and postoperative data was collected, including cardiac defect and type of surgery repair. Results: 242 children after CHDS were studied, with EF rate of 9.9%. Significant risk factor for EF during surgery was deep hypothermic circulatory arrest (DHCA) (p = 0,0043 OR = 3,1) and postoperative was laryngeal stridor (p = 0,0006 OR = 21,6). Down Syndrome and age less than 6 months were identified as indepen

Abstract: Ecuador is one of the Latin American countries where cystic fibrosis has not been thoroughly studied. The goal of this study was to establish the incidence of this specific pathology and the incidence of the 29 most common European CF mutations in Ecuador′s population.We performed a prospective-descriptive study with the intention of including patients registered at the Ecuadorian Cystic Fibrosis Foundation as well as the main pediatric hospitals in Ecuador. The inclusion criteria were clinical manifestations of cystic fibrosis plus two positive pilocarpine iontophoresis sweat tests (CI > 60 mEq/L). We tested F508del mutation by heteroduplex method and then, we confirmed these results and searched for other 28 frequent European mutations aside from F508del by a reverse dot blot technique (INNO-LiPA CFTR 29 + Tn). Sixty two unrelated patients were included. Both heteroduplex and reverse dot blot methods identified 53.22% of all mutations. The estimated Ecuadorian cystic fibrosis incidence was 1:11,252. The mutations found and their incidence were F508del (37.1%), G85E (8.9%), G542X (2.4%), N1303K (2.4%), G551D (1.6%) and R334W (0.8%). The incidence of cystic fibrosis in Ecuador is closely similar to other Latin American countries where there is a large “mestizo” population. We are reporting one of the highest incidences of G85E in the world. Ecuador es uno de los países latinoamericanos donde la fibrosis quística no ha sido profundamente estudiada. El objetivo de este estudio fue establecer la incidencia de esta patología identificar las 29 mutaciones europeas mas frecuentes que afectan a los pacientes fibroquísticos ecuatorianos. Se realizó un estudio descriptivo-prospectivo que incluyó pacientes provenientes de las Fundación Fibrosis Quística y de los principales hospitales pediátricos del Ecuador. Los criterios de inclusión fueron la presencia de manifestaciones clínicas clásicas de fibrosis quística más dos pruebas del sudor por iontoforesis de pilocarpina positivas CI > 60 mEq/L. Se utilizó heteroduplex para identificar la mutación F508del y posteriormente se confirmó dichos resultados e identificó otras 28 mutaciones frecuentes de la población europea utilizando un test de hibridación reversa in situ (INNO-LiPA CFTR 29 + Tn). Sesenta y dos pacientes fueron incluidos y se logró identificar el 53,22% de todos los alelos mutados. Las mutaciones encontradas fueron F508del (37,1%), G85E (8,9%), G542X (2,4%), N1303K (2,4%), G551D (1,6%) y R334W (0,8%). La incidencia estimada de la fibrosis quística en el Ecuador (1:11.252) es muy similar a la de otros pa

Abstract: Se efectuaron pescas exploratorias con red de enmalle alrededor de las islas Robinson Crusoe y Santa Clara (Archipiélago de Juan Fernández, Chile) en enero-febrero de 1997, realizándose un total de 14 caladas en diferentes lugares en torno a estas islas, obteniendo una captura total de 599 kg en 106 horas de reposo. Los principales recursos capturados según su aporte en peso correspondieron al tollo de Juan Fernández, Squalus mitsukurii (53,9%); jurel de Juan Fernández, Pseudocaranx chilensis (19,9%); corvina de Juan Fernández, Umbrina reedi (7,8%); vidriola, Seriola peruanus (7,3%); jerguilla de Juan Fernández, Girella albostriata (7,2%); y, otras especies (3,8%). Mediante estas experiencias se demuestra que este arte puede ser calado con relativa facilidad y seguridad en diversos lugares alrededor de estas islas. Además, los niveles de captura obtenidos hacen atractiva su utilización con el fin de obtener peces, la mayoría de los cuales son especies de alta calidad, que tuvieron tama os y pesos requeridos para consumo humano o para ser empleados como carnada en las trampas langosteras The gillnet fishing survey was conducted around Robison Crusoe and Santa Clara islands (Juan Fernandez archipelago, Chile) in January-February 1997.

Abstract: Con el objeto de buscar recursos alternativos a la langosta de Juan Fernández (Jasus frontalis), que constituye el objetivo tradicional de los pescadores artesanales, se efectuó una campa a de pesca exploratoria con trampas en torno a las islas Robinson Crusoe y Santa Clara (Archipiélago de Juan Fernández, Chile). Entre el 11 de noviembre de 1996 y el 23 de marzo de 1997 se realizaron un total de 71 salidas de pesca, en las que se caló un total de 241 trampas, entre 50 y 1000 m de profundidad. En estas experiencias se utilizaron distintos dise os de trampas: troncocónico, tetragonal y piramidal, de diferente tama o y ubicación de las entradas, y trampas langosteras con entrada en un extremo y en la parte superior. Las dos últimas, las utilizan los pescadores del archipiélago para la extracción de la langosta. Las trampas troncocónicas, tetragonales y piramidales fueron caladas con entradas circulares o rectangulares. Los únicos crustáceos capturados correspondieron a: langosta de Juan Fernández (Jasus frontalis), centolla de Juan Fernández (Paromola rathbuni), jaiba remadora (Ovalipes trimaculatus) y cangrejo dorado (Chaceon chilensis). La langosta se capturó entre 50 y 100 m; la centolla de Juan Fernández entre 100 y 300 m; el cangrejo dorado entre 200 y 1000 m; mientras que la jaiba remadora se encontró sólo en el veril de 100 m. El único recurso que presenta interés pesquero es C. chilensis, tanto por su abundancia como por la amplia distribución en profundidad y en torno a las islas analizadas Looking for alternative resources to the Juan Fernandez spiny rock lobster (Jasus frontalis), the traditional target species of the artisanal fishermen of the archipelago, an exploratory fishing campaign with fishing pots was conducted around Robinson Crusoe and Santa Clara islands.
