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.

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.
