ABSTRACT
Introduction: Upper gastrointestinal studies are routine diagnostic and therapeutic procedures. In pediatrics, however, they are limited by the need for sedation and monitoring. Objectives: Po evaluate sedation, indication, and parent perception of these exams. Patients and Methods: A prospective study of 190 pediatric upper gastrointestinal endoscopies was undertaken. Demographic data, as well as information regarding the exam was obtained. Results: Patients' average age was 8.5 +/- 4.2, mostly referred by pediatricians (60 percent) Main reason for referral was recurrent abdominal pain (29.8 percent). Patients were classified according to ASA criteria (93 percent ASA I and II). Most patients required two or more medications for optimal sedation, with satisfactory procedure in over 90 percent. Over 75.5 percent had complete amnesia, 42.7 percent presented minor discomfort after the procedure. Findings of these procedures included 61 percent of normal exams, 13.9 percent esophagitis. More findings were there result of analyses according to children's weight (over or under 14 kg), age, ASA, reason for referral, nurse's evaluation of sedation. Conclusion: Ambulatory endoscopio procedures can be performed safely in children, with moderate sedation. Requirements are adequate monitoring, and deep knowledge of resuscitation techniques.
Introducción: El estudio endoscópico alto es un procedimiento diagnóstico y terapéutico considerado de rutina, pero su realización en pediatría se encuentra limitada dada la necesidad de sedación y monitoreo adecuados. Objetivos: Evaluar la sedación, indicación y percepción de los padres del examen. Materiales y Métodos: Estudio prospectivo de 190 niños sometidos a endoscopia digestiva alta. Se obtuvieron datos bio-demográficos, tipo de sedación y resultados del examen. Resultados: La edad fue 8,5 + 4,2 años, la mayoría referidos por pediatra (60 por ciento). La principal indicación del estudio fue el dolor abdominal recurrente (29,8 por ciento). Los pacientes fueron clasificados de acuerdo al ASA (93 por ciento ASA I y II). En la mayoría se requirió de 2 ó más drogas para lograr sedación óptima. La calidad del procedimiento fue satisfactoria en más del 90 por ciento. Un 75,5 por ciento presentaron amnesia completa y un 42,7 por ciento molestias leves posterior al procedimiento. Entre los hallazgos destacaron signos de esofagitis en el 13,9 por ciento, observándose un 61 por ciento de los exámenes normales. Al analizar los pacientes por peso (mayores y menores de 14 kg), se encontraron diferencias en edad (p < 0,00001), ASA (p = 0,001), indicación de endoscopia (p = 0,001) y evaluación de la sedación por enfermera (p = 0,038). Conclusión: Procedimientos endoscópicos en niños pueden realizarse de manera segura en forma ambulatoria mediante sedación moderada. Una adecuada monitorización y conocimiento de técnicas de reanimación son básicos al momento de realizar dichos procedimientos.

Eosinophilic esophagitis in adults (EE) is a disease of unknown cause, characterized by symptoms such as reflux and dysphagia that traditionally do not respond to antacid treatment. It affects mostly young men with a strong personal or familial history of a topy asthma and allergies. We repot three male patients aged 10, 14 and 15years, all with symptoms of dysphagia, two of them with chest pain caused by spasm of the esophagus, with heterogeneous endoscopic findings which included from leucoplakia to stenosis that needed endoscopic dilatation. All of them had abnormal findings in immunity studies (prick test or IgE levels). They received treatment based on diet measures, acid suppression and leukotriene inhibitors, with satisfactory clinical, endoscopic and histological response. EE should be suspected in children and adults with esophageal symptoms and personal or family history of allergy and asthma.

Introducción: La rinosinusitis crónica (RSC) es un cuadro inflamatorio en el que las bacterias juegan un rol importante. Las exacerbaciones agudas de rinosinusitis crónica (EARSC) en pacientes posoperados no son infrecuentes. Sin embargo, su manejo es complejo debido a la aparición de nuevos agentes y el aumento de la resistencia a antibióticos. Objetivo: Desarrollar una técnica de toma de muestra en cavidades paranasales, que permita caracterizar a los agentes involucrados en EARSC en pacientes posoperados. Material y método: Se recluta ron 32 pacientes posoperados. Se realizó aspirado de seno maxilar bajo visión endoscópica. Las muestras fueron cultivadas para aerobios, anaerobios y hongos. Resultados: Se enviaron 50 muestras a cultivo, en 46 de ellas se aislaron gérmenes (92%), de los cuales 44 fueron aerobios. En 7 de las muestras se aislaron anaerobios, y en 2 se obtuvo cultivo positivo para hongos. La resistencia a betalactámicos fue de 48,2%, observándose 36% de resistencia a lo menos a dos familias de antibióticos. Discusión y conclusiones: Nuestro estudio es el primero a nivel nacional en caracterizar a los agentes involucrados en EARSC en pacientes poscirugía endoscópica nasal. Los resultados obtenidos, posicionan a los cultivos endoscópicos como una excelente herramienta clínica para estudiar las EARSC.
Introduction: Chronic rhinosinusitis (CRS) is an inflammatory condition where bacteria play an important role. Acute exacerbations of chronic sinusitis (AECS) in patients who underwent endoscopic sinus surgery (EES) are not infrequent. Treatment of these exacerbations is complex due to the emergence of new agents and to an increase in bacterial resistance. Therefore, it is important to develop methods to culture and identify these agents and their antimicrobial resistance and sensibilities. Aim: To develop a technique for recovery of pathogens in the paranasal sinuses of patients with AECS after EES. Material and Method: 32 patients that had undergone EES were recruited. Aspiration of the maxillary sinus under direct endoscopic vision was performed. Samples obtained were sent for aerobic, anaerobia and fungal cultures. Results: Of the 50 samples collected, 46 were positive. Of these, 44 cultured aerobes, 7 cultured anaerobes, and 2 cultured fungi. The resistance to betalactamic antibiotics was 48.2% with at least 36% resistance to two different types of antibiotics. Conclusion: This is the first report in Chile of the microorganisms involved in AECS after EES. The results suggest that the sampling method described here is a useful tool for the study of patients with AECS.

Background: During infancy, preventive, diagnostic and therapeutic efforts for Helicobacter pylori infection should be made. Aim: To evaluate non-invasive diagnostic methods such as stool antigen test (HpSA) and serum anti-H pylori antibody detection (IgG e IgA), compared to endoscopy-based invasive methods (histology and urease test) for the diagnosis of Helicobacter pylori infection. Patients and Methods: Thirty nine children (aged 3 to 14 years, 20 males) referred for upper gastrointestinal endoscopy, were studied. The gold standard to diagnose Helicobacter pylori infection was defined as a positive invasive diagnostic test (histology and/or urease test). Sensitivity (S), specificity (E) and positive (PPV) and negative (NPV) predictive values were obtained for HpSA and serum antibodies. Results: Ten children (26 percent) were infected with H pylori. S, E, PPV and NPV for HpSA were 90, 100, 100 and 97 percent, respectively. The figures for serum IgG were 81, 97, 89 and 93 percent, respectively and for IgA, 90, 76, 36 and 96 percent, respectively. Conclusions: HpSA was sensitive and specific as a clinical and epidemiological tool to evaluate H pylori infection in children. Serology was not as accurate, but IgG had a better performance than IgA.
