INTRODUCCION: La prevalencia de la infección por Helicobacter pylori (HP) y su caracterización histopatológica en niños en el Perú es insuficientemente conocida. OBJETIVOS: Reportar las características clínicas e histopatológicas de la infección por HP en niños del Hospital Nacional Cayetano Heredia (HNCH) en Lima, Perú. METODOS: Se obtuvo información sobre endoscopías y biopsias realizadas en niños en el periodo de julio 2003 a noviembre 2006. RESULTADOS: De 210 endoscopías se obtuvo biopsias gástricas en 111. La prevalencia de HP fue de 45.9% (51 de 111 pacientes). Los niños HP positivos tuvieron mayor edad que los HP negativos (11 versus 8.9 años, p = 0.009). En los HP positivos la presencia endoscópica de “gastritis nodular” (GN) fue significativamente mayor (p=0.001), mientras que la “esofagitis” fue más frecuente entre los HP negativos (p = 0.001). 8/11 ...

Study objective: To describe the clinical features, radiographics, laboratory and bacteriologic findings of pediatric patients with tuberculous pleural effusion. Material and Methods: It is a retrospective study. We have collected information from medical records of inpatients < 16 years old, who were admitted at Hipolito Unanue Hospital from January 2003 to December 2012, with diagnosis of tuberculous pleuritis. Results: Ninety – six children were diagnosed with tuberculous pleural effusion. The median age was 11 years. 60.42% of the patients were eutrophic, 26.04%were overweight or obese and only 13.65%suffered of malnutrition. Positive tuberculin skin tests were seen in 89.86%. Pleural effusion was the sole radiographic manifestation in 36.5% of cases and parenchymal disease was associated in 63.5% of the patients. Bacteriologic confirmation of tuberculosis was achieved in 13 cas...
