Lung mechanics in pediatric acute respiratory distress syndrome associated to acute COVID-19 and MIS-C: implications for therapies and outcomes.

Objective: To describe lung mechanics in Pediatric Acute Respiratory Distress Syndrome (PARDS) associated with acute COVID-19 and MIS-C with respiratory failure.

Methods: A concurrent multicenter observational study was performed, analyzing clinical variables and pulmonary mechanics of PARDS associated with COVID-19 in 4 Pediatric intensive care units (PICU) in Peru. The subgroup analysis included PARDS associated with multisystem inflammatory syndrome in children (MIS-C), MIS-PARDS, and PARDS with COVID-19 primary respiratory infection, C-PARDS.

Posterior reversible encephalopathy syndrome in a child with severe multisystem inflammatory syndrome due to COVID-19.

Posterior reversible encephalopathy syndrome is a rare clinical and radiological syndrome characterized by vasogenic edema of the white matter of the occipital and parietal lobes, which are usually symmetrical, resulting from a secondary manifestation of acute dysfunction of the posterior cerebrovascular system. We describe a case of posterior reversible encephalopathy syndrome secondary to SARS-CoV-2 infection in a 9-year-old boy who developed acute hypoxemic respiratory failure and required assisted mechanical ventilation. The child developed multisystem inflammatory syndrome, and he was monitored in the pediatric intensive care unit and was provided mechanical ventilation and vasoactive agents for hemodynamic support.

Association of Cancer Diagnosis and Therapeutic Stage With Mortality in Pediatric Patients With COVID-19, Prospective Multicenter Cohort Study From Latin America.

Background: Children with cancer are at risk of critical disease and mortality from COVID-19 infection. In this study, we describe the clinical characteristics of pediatric patients with cancer and COVID-19 from multiple Latin American centers and risk factors associated with mortality in this population.

Methods: This study is a multicenter, prospective cohort study conducted at 12 hospitals from 6 Latin American countries (Argentina, Bolivia, Colombia, Ecuador, Honduras and Peru) from April to November 2021.
