Unfortunately, the course of dengue infection is difficult to predict, even with the clinical classification described in management guidelines. In addition, the lack of specificity of the warning signs has caused an increase in hospital admissions. Therefore, it is critical to develop more accurate diagnostic tools or models in order to alleviate the burden of disease and improve management and treatment outcome. For this reason, the objective of this study was to determine the predictive value of the neutrophil/lymphocyte and platelet/lymphocyte ratio of the ultrasound characteristics presented by pediatric patients with a diagnosis of dengue hospitalized in the pediatric service of the Loreto Regional Hospital, 2014-2019. For this purpose, a quantitative study, of a predictive level, was designed. The sample consisted of 96 patients, selected using a simple random probabilistic sampli...

En la presente investigación se determinó la actividad antibacteriana in vitro del extracto acuoso de hojas y corteza de Vismia angusta (pichirina) sobre Escherichia coli y Staphylococcus aureus a concentraciones de 200, 300 y 400 mg/mL. Para la determinación de la actividad antibacteriana se utilizó la técnica de disco difusión (Kirby- Bauer), prueba que permite medir la susceptibilidad in vitro de los microorganismos patógenos, utilizando como control positivo la gentamicina 10 ug, y como control negativo suero fisiológico 0.9 %. Al analizar los resultados de los ensayos se observó que el extracto acuoso de corteza de Vismia angusta a concentración de 400 mg/mL demostró ser moderadamente activo frente a Escherichia coli (57.68 %) y frente a Staphylococcus aureus (59.60 %); a concentración de 300 mg/mL demostró ser moderadamente activo frente a Escherichia coli (53.54 %) y ...
