<jats:p>Human Norovirus is currently the main viral cause of acute gastroenteritis (AGEs) in most countries worldwide. Nearly 50 years after the discovery of the “Norwalk virus” by Kapikian and colleagues, the scientific and medical community continue to generate new knowledge on the full biological and disease spectrum of Norovirus infection. Nevertheless, several areas remain incompletely understood due to the serious constraints to effectively replicate and propagate the virus. Here, we present a narrated historic perspective and summarize our current knowledge, including insights and reflections on current points of interest for a broad medical community, including clinical and molecular epidemiology, viral–host–microbiota interactions, antivirals, and vaccine prototypes. We also include a reflection on the present and future impacts of the COVID-19 pandemic on Norovirus infection and disease.</jats:p>

<jats:p>La infección por Helicobacter pylori es una condición frecuente, que a largo plazo se asocia con desarrollo de enfermedad ulceropéptica y eventualmente cáncer gástrico, que se podrían prevenir con un tratamiento oportuno. Lo óptimo sería lograr un éxito de erradicación mayor al 90%, pero los tratamientos empíricos recomendados no logran esas tasas en condiciones reales.Objetivo: Determinar el porcentaje de éxito del tratamiento empírico de erradicación de primera línea contra H. pylori en pacientes pediátricos atendidos en un hospital terciario.Pacientes y Método: Estudio descriptivo retrospectivo en pacientes con infección por H. pylori detectado en biopsias gástricas y que hubieran recibido tratamiento antibiótico de primera línea durante el periodo 2017-2021. Se consideró erradicación exitosa el resultado negativo de test de antígeno en deposiciones o nuevas biopsias luego de ≥ 1 mes de finalizado el tratamiento.Resultados: Se identificaron 82 pacientes con infección por H. pylori, de los cuales 53 recibieron tratamiento de erradicación. De éstos, 26 (49%) fueron controlados con test de erradicación luego del tratamiento y en ellos el porcentaje de éxito fue de solo 38% (10/26).Conclusiones: La tasa de erradicación con los esquemas empíricos utilizados fue menor a la esperada, lo que evidencia el desafío de buscar estrategias más efectivas de tratamiento incluyendo el estudio de susceptibilidad a antimicrobianos. La adherencia de los pacientes al protocolo de seguimiento también fue baja, lo que deberá reforzarse en el futuro para poder realizar un manejo clínico más adecuado. </jats:p>

<jats:title>ABSTRACT</jats:title><jats:p>Fructose is a highly abundant carbohydrate in western diet and may induce bowel symptoms in children as in adults. The main objective of this study is to describe the frequency of fructose malabsorption (FM) in symptomatic patients 18 years or younger undergoing fructose breath test in a single tertiary center between 2013 and 2018, and to evaluate whether certain symptoms are related to positivity of the test. Out of 273 tests 183 (67%) were compatible with FM. The most frequent pretest symptom in the overall study population was bloating (83%), followed by abdominal pain (73%). Patients with positive test were younger than those with a negative test (median 5 vs 8 years, <jats:italic>P</jats:italic> < 0.001). In multivariate analysis, which included age, sex, and symptoms (diarrhea, abdominal pain, bloating, nausea), only age <6 years (odds ratio 2.93, 95% confidence interval 1.64–5.23) and absence of nausea (odds ratio = 3.32, 95% confidence interval 1.56–7.05) were associated with FM.</jats:p>
