RESUMO

Los tumores carcinoides derivan de las células neuroendocrinas de cualquier parte del organismo (más frecuentemente del tubo digestivo, el páncreas y los bronquios). Son los tumores endocrinos gastrointestinales más frecuentes, ya que representan un 75% de estas neoplasias, y el tumor maligno gastrointestinal más frecuente en los niños. Su diagnóstico suele realizarse de manera casual en el 0,3-0,9% de las apendicectomías, y son menos frecuentes en la edad pediátrica. Presentamos el caso de un tumor carcinoide en un niño de 12 años de edad y realizamos una revisión de esta patología (AU)


Carcinoid tumors derive from neuroendocrine cells at different anatomic locations (although they are most commonly found at the gastrointestinal tract, pancreas and bronchial airway) and are the most common gastrointestinal endocrine tumors, of which they represent 75%; being also the most common gastrointestinal malignant tumour in children. Diagnosis is often incidental (in around 0.3 to 0.9% of appendectomies, and less common in children). We report the case of a carcinoid tumor in a pediatric patient aged 12 years, providing aswell a review of this pathology (AU)

RESUMO

Objetivo: Analizar la eficacia y tolerancia de la ventilación mecánica no invasiva (VMNI) a través de unas cánulas de oxigenoterapia de alto flujo en niños con insuficiencia respiratoria moderada y/o tras retirada de ventilación mecánica. Pacientes y métodos: Estudio clínico prospectivo observacional en el que se estudió a 34 pacientes de edades comprendidas entre 9 meses y 17 años, tratados con VMNI a través de unas cánulas nasales de oxigenoterapia de alto flujo de adulto. Se analizaron las siguientes variables: edad, sexo, frecuencia respiratoria, cardiaca, saturación de oxígeno, gasometría, mejoría clínica, tolerancia, aparición de complicaciones y fracaso del tratamiento. Resultados: Trece pacientes recibieron VMNI de forma programada tras la retirada de la ventilación mecánica y 21 por insuficiencia respiratoria. El 82,3% de los pacientes mejoraron clínicamente y/o toleraron la retirada de ventilación mecánica, aunque no se observó un cambio significativo en la frecuencia respiratoria, frecuencia cardiaca, pH, pCO2 ni saturación. En 6 pacientes (17,6%) la VMNI no fue efectiva y precisó cambio a mascarilla nasal o buconasal (5 pacientes) o intubación (1 paciente). Otros dos pacientes (5,9%) precisaron cambio de interfase a mascarilla nasal o nasobucal, uno por presentar erosión nasal y otro porque aunque mejoró clínicamente, presentaba fugas excesivas. La duración del tratamiento fue de 48 h (rango 1 a 312 h). Conclusiones: La VMNI a través de cánulas nasales de alto flujo es eficaz y bien tolerada en un importante porcentaje de niños tras retirada de ventilación mecánica o con insuficiencia respiratoria moderada (AU)


Objective: To analyse the efficacy and tolerance of non-invasive mechanical ventilation (NIMV) via high-flow oxygen therapy nasal cannulae in children after withdrawal of mechanical ventilation and/or with moderate respiratory insufficiency. Patients and methods: A prospective observational clinical study including 34 children between9 months and 17 years treated with NIMV via high-flow oxygen therapy nasal cannulae. The following variables were analysed: age, sex, respiratory rate, heart rate, oxygen saturation, blood gases, clinical improvement, tolerance, onset of complications and treatment failure. Results: NIMV was used in 13 children after withdrawal of mechanical ventilation and in 21 with respiratory failure. A high percentage (82.3%) of patients improved clinically and/or allowed the mechanical ventilation to be withdrawn, but there were no significant changes in respiratory rate, heart rate, pH, pCO2 or saturation. NIMV was not effective in 6 patients (17.6%) and required change to a nasal or buconasal mask (5 patients) or intubation (1 patient). Two patients (5.9%) required change of interface to a nasal or buconasal mask, one had nasal erosion, and another, although improved clinically, showed excessive leakage. The duration of treatment was 48 hours (range 1 to 312 hours).Conclusions: Non-invasive mechanical ventilation via high-flow oxygen therapy nasal cannulae is effective and well tolerated in a high percentage of children after withdrawal of mechanical ventilation or with moderate respiratory insufficiency (AU)

RESUMO

OBJECTIVE: End-tidal carbon dioxide (PetCO(2)) is a good predictor of circulation and metabolism. There are different studies that suggest PetCO(2) monitoring is a valuable and reliable tool to follow acidosis in pediatric patients with diabetic ketoacidosis. Acute gastroenteritis can cause acidosis, therefore, capnography could be useful in these situations. The objective was to determine the relationship between PetCO(2) and bicarbonate (HCO3) in pediatric patients with acute gastroenteritis and acidosis. METHODS: Clinical, prospective, observational study from April 2006 to January 2007. Children with acute gastroenteritis and dehydration and pH < 7.30 and HCO3 < 20 meq/L in laboratory tests were included. Exclusion criteria included patients with not well tolerated capnography and respiratory illness. Initial and post treatment PetCO(2) and HCO3 were collected as well as demographic data, physical examination data, laboratory tests and hospitalization data. RESULTS: Twenty-five children were included in the final analysis (10 female, 15 male). The mean age was 11.6 + 10 months (1-144 months). The correlation between PetCO(2) and serum bicarbonate was statistically significant with a Pearson's correlation coefficient of r = 0.61 for initial values and r = 0.75 for post treatment values. CONCLUSIONS: Capnography offers a noninvasive measurement of acidosis in pediatric patients with acute gastroenteritis and dehydration.

RESUMO

Objetivos: El estudio del CO2 espirado mediante capnografía (PetCO2) proporciona un parámetro no invasivo del metabolismo sistémico, la perfusión y la circulación. Existen estudios que relacionan PetCO2 con el estado metabólico de pacientes pediátricos con cetoacidosis diabética. La gastroenteritis aguda es causa de acidosis metabólica, por lo que la capnografía podría ser útil en estas situaciones. El objetivo fue determinar la relación entre el PetCO2 y el bicarbonato (HCO3) en plasma en niños con gastroenteritis y acidosis. Material y métodos: Estudio prospectivo desde abril de 2006 hasta enero de 2007 con niños con deshidratación secundaria a gastroenteritis y que presentaban en la analítica un pH inferior o igual a 7,30 y un HCO3 inferior a 20 mEq/l. Se excluyeron niños con mala tolerancia del capnógrafo y con patología pulmonar de base. Las variables recogidas fueron PetCO2 y HCO3 basal y a la hora del inicio de fluidoterapia intravenosa, datos epidemiológicos, clínicos, bioquímicos y necesidad de hospitalización. Resultados: La muestra fue de 25 pacientes (10 niñas y 15 niños) con una edad media de 11,6 + 10 meses (1-144 meses). Se encontró asociación estadísticamente significativa entre PetCO2 y bicarbonato tanto basal como a la hora de la fluidoterapia intravenosa y se obtuvo un coeficiente de correlación de Pearson r = 0,61 y r = 0,75, respectivamente. Conclusiones: La capnografía es un método no invasivo útil para estimar el estado metabólico de pacientes pediátricos con gastroenteritis y deshidratación (AU)

RESUMO

Introducción Se ha observado durante los últimos años un notable aumento en el número de urgencias psiquiátricas atendidas en los servicios de urgencias de pediatría. Realizamos este estudio con el objetivo de definir las características de estos pacientes. Pacientes y métodos Estudio descriptivo, prospectivo y transversal que incluyó todas las urgencias psiquiátricas atendidas en el servicio de urgencias de pediatría del Hospital General Universitario Gregorio Marañón de Madrid, desde el 1 de octubre de 2004 hasta el 31 de marzo de 2005. Se analizaron: edad, sexo, hora de la consulta, día de la semana, día del mes, mes, antecedentes psiquiátricos, tratamiento psiquiátrico farmacológico previo, acompañante del menor, diagnóstico y destino final del paciente. Resultados Se registraron 79 urgencias psiquiátricas sobre 36.449 urgencias totales (0,21 %). El 48,1 % eran niños y el 51,9 % niñas. La edad (media 62 DE) fue de 13,73 6 2,5 años. Se observó mayor demanda asistencial los lunes (19 %), por la tarde y en los meses de enero y febrero. El 13,23 % de los pacientes fueron traídos por servicios de urgencias extrahospitalarios. Los principales diagnósticos fueron: trastorno de conducta (36,76 %), trastorno de ansiedad (20,58 %) e ideación o intento autolítico (13,23 %). Se observó un claro predominio de niños en el trastorno de conducta (67,85 %) y de niñas en el trastorno de ansiedad (71,42 %) y en la ideación o intento autolítico (76,92 %). La tasa de hospitalización de los pacientes con patología psiquiátrica urgente fue del 32,35 %. Conclusiones Observamos una baja incidencia de patología psiquiátrica en nuestro servicio de urgencias de pediatría. Son pacientes de 11-15 años, sin diferencias en cuanto al sexo. Se objetivó un pico asistencial al final de la tarde e inicio de la noche, los lunes y en los meses de enero y febrero. El diagnóstico más común fue el trastorno de conducta. Destaca la altísima tasa de hospitalización de estos pacientes, más de seis veces superior a la tasa general del servicio de urgencias de nuestro hospital


Introduction In the last few years, a marked increase in the number of psychiatric emergencies treated at pediatric emergency departments has been observed. The aim of the present study was to characterize these patients. Patients and methods We performed a descriptive, prospective, cross sectional study, based on all psychiatric emergencies treated at the pediatric emergency department of Hospital General Universitario Gregorio Marañón, Madrid, from 1-10-04 to 31-3-05. The following variables were analyzed: age, sex, time of consultation, day of the week, day of the month, month of the year, psychiatric antecedents, previous psychiatric pharmacologic treatment, the person or service who took the child to hospital, diagnosis, and whether the patient was admitted to the hospital. Results Of a total of 36,449 emergencies, 79 were psychiatric (0.21 %). Sex rates were 48.1 % boys and 51.9 % girls. The mean (62 SD) age was 13.73 6 2.5 years. Visits were most frequent on Mondays (19 %), in the evening, and in January and February. A total of 13.23 % of the patients were brought by extrahospital services. The main diagnoses were: behavioral disorders (36.76 %), anxiety disorders (20.58 %) and suicidal ideation or suicide attempt (13.23 %). There was a clear male predominance in behavioral disorders (67.85 %) and a female predominance in anxiety disorders (71.42 %) and suicidal ideation or suicide attempt (76.92 %). The hospitalization rate among these patients was 32.35 %. Conclusions The incidence of psychiatric disorders in our pediatric emergency department was low. The patients were aged 11-15 years old, without differences between the sexes. Peak demand was reached on Mondays in January and February, at the end of the evening and beginning of the night. The most common diagnosis was behavioral disorder. The hospitalization rate was exceptionally high, more than 6 times higher than the average in our hospital
