<title>Abstract</title> Introduction: Healthcare-associated infections are a public health problem, resulting in increased morbidity, mortality and costs to patients. The present study aims to analyze an in-hospital outbreak of <italic>Ralstonia insidiosa</italic> in children admitted to a pediatric referral hospital, with a focus on the control and prevention measures implemented. Methodology: An observational prospective study was conducted from the beginning of an outbreak of <italic>Ralstonia insidiosa</italic> to its end, with emphasis on the control measures implemented by a pediatric referral hospital. Results: We found 19 cases in 19 epidemiological weeks, with an attack rate of 1.76%, mainly affecting children hospitalized for more than 14 days, with invasive devices, admitted to pediatric intensive care (PICU) and with underlying disease. The clinical presentation was characterized by vomiting, fever and cough. The control of the outbreak was archived based on the installation of epidemiological and antimicrobial surveillance approach. Conclusions: We conclude that <italic>Ralstonia insidiosa</italic> is an emerging nosocomial, opportunistic and antibiotic-resistant pathogen affecting children with risk factors (invasive devices, immunocompromised and admitted to PICU), in whom it causes morbidity and mortality; furthermore, decision making based on a combined approach of epidemiological and antimicrobial surveillance with available resources can serve to control the outbreak.

Introduction. The objective of this study is to describe the characteristics of dog bite injuries in children seen at a children's hospital in Bolivia. Population and methods. This was an observational, retrospective study in patients seen between 2017 and 2021. Results. A total of 769 patients were studied. Dog bite injuries accounted for 5.6% of emergency visits and 0.8% of hospitalizations. They were more frequent in children younger than 5 years (55.1%), in whom the following were observed: greater injury severity (p = 0.008), history of animal provocation (p = 0.048), known attacking animal (p < 0.036), domestic accident (p = 0.021), greater frequency of post-exposure prophylaxis with anti-rabies serum (p = 0.005), and maxillofacial area as the main region involved (p < 0.001). There were 3 deaths due to human rabies and 1 due to hypovolemic shock. Conclusion. Dog bite injuries are a frequent cause of visit to the emergency department and hospitalization in pediatrics and have specific characteristics in children younger than 5 years.

(2022) Carla Patricia Escalera Muñoz; Melvy Escobar Carrillo; Raul Copana Olmos MD MSC; Maria Elena Calderon-Lopez
El Virus de la Inmunodeficiencia Humana (V.I.H.) en etapas avanzadas confiere al portador la susceptibilidad para desarrollar infecciones oportunistas. Se sabe poco sobre el COVID-19 en pacientes con infección por el VIH, y a pesar de que la mayoría estos pacientes coinciden con los factores de riesgo de mal pronóstico cuando hay una coinfección con el COVID-19, se han informado muy pocos casos referentes al tema. En este artículo se presentamos un caso clínico de una paciente pediátrica, sin antecedentes patológicos de importancia, con diagnósticos iniciales de pénfigo y neumonía que, después de posteriores estudios pasó a diagnóstico de VIH-SIDA / COVID 19.
