Hepatotoxicidad por fármacos o productos naturales en ni˜nos / Hepatotoxicity due to drugs or natural products in children

Introducción: La incidencia de las reacciones adversas a medicamentos en pediatría se ha establecido recientemente en 15,1 reacciones por 1.000 niños. Representa un 2% de las admisiones de un hospital pediátrico, similares a las del paciente adulto, y de ellas solo un pequeño porcentaje (menos del 8%) cursan con afectación hepática, que puede ir desde un ligero aumento de las transaminasas hasta una hepatitis fulminante. El objetivo de este estudio ha sido determinar la importancia (frecuencia, formas de presentación, gravedad y cronificación) de la hepatotoxicidad por fármacos o remedios naturales en la población pediátrica. Pacientes y método: Se han incluido a todos los pacientes pediátricos, neonatos y niños en los que se ha sospechado una reacción hepatotóxica, remitidos de 8 hospitales españoles participantes. Para el análisis de la causalidad de cada caso se aplica la escala de Council for International Organizations of Medical. Sciences (CIOMS). Resultados y conclusiones: Se estudian un total de 36 reacciones hepatotóxicas en 33 niños. Los grupos farmacológicos involucrados con mayor frecuencia fueron los antitinfecciosos (71%). Amoxicilina-clavulánico fue el fármaco individual responsable del mayor número de casos (31,4%). Se concluye que el registro de hepatopatías asociadas a medicamentos ha demostrado ser un instrumento útil para la creación de una red activa de especialistas motivados en la detección y comunicación de incidencias de hepatopatía tóxica, aumentando las garantías de certeza diagnóstica(AU)

Introduction: The incidence of adverse drug reactions in children has recently been established at 15.1 reactions per 1000 children. This represents 2% of admissions to a paediatric hospital, and is similar to adult patients. Only a small percentage (less than 8%) may have liver involvement, which can range from a slight increase in transaminases to fulminant hepatitis. The aim of this study was to determine the importance (frequency, types of presentation, severity and chronicity) of hepatotoxicity by drugs or natural remedies in the paediatric population. Patients and method: All paediatric patients, neonates and children who had suspected hepatotoxic reactions notified by the eight participating Spanish hospitals. The Council for International Organizations of Medical Sciences (CIOMS) scale was used for the analysis of causality in each case. Results and conclusions: We studied a total of 36 hepatotoxic reactions in 33 children. The drug classes most frequently involved were antimicrobials (71%). Amoxicillin-clavulanate was the individual drug responsible for the greatest number of cases (31.4%). We conclude that the registration of drugs associated with liver disease has proved a useful tool for creating an active network of motivated specialists in detecting and reporting incidents of toxic liver disease, ensuring increasing diagnostic accuracy(AU)

Infección nosocomial del tracto urinario en niños críticos / Nosocomial urinary tract infection in critical pediatric patients

Objetivos: Determinar la densidad de incidencia, etiología y factores de riesgo de la infección de orina nosocomial (ITUn) en una UCIP de segundo nivel. Diseño: Estudio prospectivo descriptivo durante un periodo de 1 año que incluyó a 104 pacientes ingresados durante más de 48 h en nuestra UCIP. Se recogieron urocultivos diarios a los pacientes con sonda vesical hasta su retirada y cada 48 h a los no sondados hasta el alta. Ámbito: Unidad de cuidados intensivos pediátricos de segundo nivel. Pacientes: Se incluyó a todos los pacientes que ingresaron por más de 48 h en el año 2009. Se excluyó a los menores de 15 días y a los que presentaban una infección de orina o pielonefritisal ingreso o antes de las 48 h tras su ingreso. Resultados: Seis pacientes presentaron una ITUn (el 5,8% de los ingresos), con una densidad de incidencia de 5/1.000 pacientes/día y de 12,19/1.000 días de sonda. Se identificaron 4casos por Escherichia coli (uno, multirresistente) y 2 por Candida albicans. Los niños con ITUn tuvieron significativamente más antecedentes personales y mayor estancia que los niños sin infección y, aunque sin significación estadística, menor edad y mayor número de días con sonda. Conclusiones: Nuestra densidad de incidencia de infección de orina asociada a dispositivo es superior a la publicada; esto puede deberse, entre otras causas, a las características de los pacientes atendidos y al método exhaustivo empleado para su detección (AU)

Objective: To determine the incidence, etiology and risk factors of nosocomial urinary tractinfections (nUTI) in a second level Pediatric Intensive Care Unit (PICU).Patients and methods: A prospective study of 104 patients admitted to the PICU with a length of stay of more than 48 hours was carried out over a one year period (January to December2009) to study the incidence and risk factors of nUTI. Urine samples were collected and cultured in all patients admitted for more than 48 hours to our PICU. Those needing indwelling urinary catheters had urine samples collected upon admission and every 24 hours until catheterretrieval, while those who did not need catheters had samples collected upon admission and every 48 hours until discharge from the PICU. Results: Six patients (5.8% of those admitted) were diagnosed of nUTI, with an incidence density of 5/1000 patients/day and 12.2/1000 catheterization days. Four of these were caused byE. coli (including a multiresistant strain), and two by C. albicans. Patients suffering nUTIs had significantly more relevant medical antecedents and a longer period of admittance than patients without nUTI. A statistically non significant tendency towards increased infection risk was also found in younger patients and in those who needed an indwelling catheter for longer periods. Conclusions: We found a higher incidence density of catheter associated nUTI than in other reports. This at least partially could be due to the characteristics of our patients, and to the exhaustive methodology used for detection (AU)

[Severe iatrogenic airway obstruction due to lingual lymphangioma]. / Obstruction iatrogène sévère de la voie aérienne par un lymphangiome lingual.

Lymphangioma of the tongue is a rare and benign tumour involving congenital and cystic abnormalities derived from lymphatic vessels. Treatment modalities include surgery and a large number of different intralesional injections of sclerosing agents. Presently, OK-432 (Picibanil(®)) is the preferred sclerosant and when administered intralesionally will result in inflammation, sclerosis, and cicatricial contraction of the lesion. We report a case of microcystic lymphangioma of the tongue in a 5-year-old boy treated with an intralesional injection of OK-432. In the immediate postoperative period, the patient suffered severe diffuse swelling, progressive upper airway obstruction with inspiratory stridor, and respiratory distress requiring emergency fiberoptic nasotracheal intubation. Although OK-432 injections are found to be safe and effective as a first line of treatment for lymphangiomas, local swelling with potentially life-threatening airway compromise should be anticipated, especially when treating lesions near the upper airway.
