Se presentan dos casos de pacientes, naturales de Requena, ciudad a 160 Km al suroeste de Iquitos, departamento de Loreto, selva baja, con síntomas moderados de COVID-19, quienes fueron inyectados con ivermectina de uso veterinario por vía subcutánea en el hombro, como parte de un tratamiento que pudiera tener cierto efecto benéfico sobre la enfermedad. Cinco a ocho días después, en las zonas de inoculación, notaron un nódulo eritematoso que se tornó necrótico, dejando una úlcera redondeada con levessignos inflamatorios. La cicatrización fue lenta.

Introduction: Malaria is a parasitic disease caused by Plasmodium sporozoites. Peruvian National Regulations for Malaria and Severe Malaria state that active surveillance of febrile patients is the main activity to perform, since it allows early case detection.Objective: To determine the usefulness of fever as a clinical predictor for malaria in endemic areas of Loreto; sensitivity and specificity of fever were also assessed.Material and Method: We prospectively included 400 febrile patients who presented to the Malaria Program at Loreto Regional Hospital from October to December 2002.Results: We found a 42.1% sensitivity (95% CI: 31.6-53.3), 62.7% specificity (95% CI: 57.3-67.7), 20.9% positive predictive value (95% CI: 15.2-28.0), 82.2% negative predictive value 82.2 (95% CI: 76.9-86.5), 58,8% accuracy (95% IC: 53,9-63,5). Fever (axillary temperature > 37,5 degrees Celsius...

Introduction: Malaria is an endemic parasitic disease in northern Peru, both in the coast and in the jungle. There is still poor knowledge about the incidence of malaria in pregnant women, as well as about congenital malaria and some associated variables.Objective: To determine the cumulative incidence of malaria in pregnant women during a 15-month period in Hospital Regional de Loreto, and to determine the incidence of congenital malaria.Material and Method: An analytical epidemiological study aiming to determine the association between malaria in pregnant women and: low birth weight, prematurity, prior malaria infection, first pregnancy, being less than 21 years old, and the presence of fever with malaria, using statistical inference, odds ratios and confidence intervals, chi squares and p statistics.Results: The cumulative incidence of malaria in pregnant women followed...

Se describe el caso de un paciente varón, de 13 años de edad, procedente de la ciudad de Iquitos con cuadro clínico de Dengue y que cumplía con los criterios de dengue hemorrágico. La gravedad de este caso de dengue hemorrágico fue de grado II. El diagnóstico fue confirmado por serología. El serotipo encontrado fue el tres. Este es el primer caso de dengue hemorrágico documentado ocurrido el Hospital Regional de Loreto.

Early childhood enteric infections have adverse impacts on child growth and can inhibit normal mucosal responses to oral vaccines, two critical components of environmental enteropathy. To evaluate the role of indoleamine 2,3-dioxygenase 1 (IDO1) activity and its relationship with these outcomes, we measured tryptophan and the kynurenine–tryptophan ratio (KTR) in two longitudinal birth cohorts with a high prevalence of stunting. Children in rural Peru and Tanzania (N = 494) contributed 1,251 plasma samples at 3, 7, 15, and 24 months of age and monthly anthropometrics from 0 to 36 months of age. Tryptophan concentrations were directly associated with linear growth from 1 to 8 months after biomarker assessment. A 1-SD increase in tryptophan concentration was associated with a gain in length-for-age Z-score (LAZ) of 0.17 over the next 6 months in Peru (95% confidence interval [CI] = 0.11â€...
