Her hemodynamics stabilized with resolution of thrombi while on venoarterial extracorporeal membrane oxygenation (ECMO) and systemic heparinization.
Meaning: In selected cases, ECMO with systemic heparinization may rescue patients from acute life-threatening pulmonary thromboembolism even without reperfusion therapy.

Finding: We present a case of a 7-year-old female with a prior asymptomatic infection with SARS-CoV-2 who subsequently developed encephalopathy and status epilepticus in association with myelin oligodendrocyte glycoprotein (MOG) antibody positivity.
Meaning: Here we present the first case of postinfectious of a MOG spectrum disorder associated with prior SARS-CoV-2 infection in a pediatric patient.

Clin Exp Pediatr. 2021;64(3):136-138. Published online July 21, 2020

Web of Science 3 Crossref 5

Question: The use of renin-angiotensin system (RAS) blockers during pregnancy causes lethal neonatal complications.
Finding: A neonate, whose mother took a RAS blocker during pregnancy, was diagnosed with renal tubular dysgenesis. He presented with respiratory failure, severe refractory hypotension, and anuria requiring continuous dialysis.
Meaning: Physicians should consider any degree of RAS fetopathy in a newborn born to a hypertensive mother who had use of RAS blockers during her pregnancy.

Salivary and lacrimal gland enlargement with serum immunoglobulin G4 elevation

Jinseok Lee, Da-Eun Kim, Jeong-Hwan Yang, Misun Lim, Hye Yung Yum, JoongGon Kim

Clin Exp Pediatr. 2021;64(2):93-95. Published online December 8, 2020

Question: What diseases should be considered in a 15-year-old girl presenting enlarged lacrimal and salivary glands?
Finding: Laboratory tests revealed elevated IgG4 levels. A submandibular gland biopsy showed lymphoplasmacytic infiltration and more than 40 immunoglobulin G4 (IgG4)-positive cells per high-power field. The patient was diagnosed with IgG4-related disease.
Meaning: Although rare in children, IgG4-related disease should be considered a differential diagnosis in children with enlarged salivary and lacrimal glands.
