We describe the demographic, clinical, radiological, and laboratory findings relating them also to the severity and clinical outcome of 129 children (0–18 years) who were admitted to a tertiary care pediatric hospital in Mexico City due to severe acute respiratory syndrome coronavirus 2 infection between April 1, 2020 and March 31, 2021. The infection was confirmed using reverse transcription‐polymerase chain reaction Fever (82.2%), tachypnea (72.1%), and cough (71.3%) were the most reported signs at the moment of hospitalization. The most frequent radiological pattern that stood out was the interstitial pattern (66.7%). History of oncologic pathology (25.6%) was the most frequent past medical history. Non‐steroidal anti‐inflammatory drugs (93%), antibiotics (57.4%), and steroids (40.3%) were the most common medication given. The average hospitalization stay was 14.2 days, and 21.7% of the total patients required transfer to the intensive care unit. At discharge, 20.2% required oxygen on an outpatient basis, and unfortunately, 7.0% of the patients who were admitted to the institute for COVID‐19 died. Our findings confirm that COVID‐19 in children has a mild presentation except for patients with hematologic/oncologic comorbidities who had severe presentations.

The infection was confirmed using RT-PCR. Fever (82.2%), tachypnea (72.1%) and cough (71.3%) were the most commonly reported signs at the moment of hospitalization. The most frequent radiological pattern that stood out was the interstitial pattern (66.7%). History of oncologic pathology (25.6%) was the most frequent past medical history. ESR (erythrocyte sedimentation rate) was the only laboratory value significantly associated with severity (p=0.015). NSAIDs (93%), antibiotics (57.4%), and steroids (40.3%) were the most common medication given. The average hospitalization stay was 14.2 days, 21.7% of the total patients required transfer to the intensive care unit.

Our findings confirm that COVID‐19 in children has a mild presentation except for patients with hematologic/oncologic co-morbidities which had severe presentations.

Antecedentes: las cardiopatías congénitas son la principal causa de defectos anatómicos en los recién nacidos a nivel mundial. En las últimas décadas ha mejorado la sobrevida de los pacientes que requieren cirugías correctivas o paliativas, aún las de mayor complejidad. Objetivo: determinar la sobrevida de pacientes con cardiopatías congénitas operados en el Hospital María, Especialidades Pediátricas (HMEP) en el 2017. Metodología: se trata de un estudio transversal con componente analítico de 120 pacientes intervenidos quirúrgicamente en el año 2017. Se estimó la tasa de sobrevida a 1 año posterior a la cirugía. Los datos fueron extraídos de los expedientes clínicos y fueron registrados en una base de datos de Microsoft Access, para el análisis de datos se utilizó STATA 15.0. Resultados: la tasa de sobrevida a 1 año fue del 87.5 por cada 100 cardiocirugías realizadas. Se encontró diferencias significativas entre los vivos y fallecidos para nivel socioeconómico, clasificación RACHS-1, y Escala ROSS. Además, se encontró asociación con mortalidad en aquellos pacientes que presentaron cardiopatías cianóticas, otras malformaciones congénitas y complicaciones durante la estancia hospitalaria. Conclusiones: la tasa de sobrevida encontrada en este estudio está acorde con la literatura internacional. Se recomienda profundizar en nuevos estudios que establezcan factores de riesgo de mortalidad en estos pacientes.
