Open set Neonatal urology | 4 minA newborn finding consistent with hypospadias should stop routine circumcision and prompt pediatric urology assessment before an irreversible procedure.
Open set Neonatal infectious diseases | 4 minFor a well term newborn exposed to recurrent genital HSV at delivery, waiting until about 24 hours for mucosal surveillance swabs helps distinguish viral replication from transient maternal contamination.
Open set Neonatal radiology and lactation safety · 4 min · 3 sourcesMaternal diagnostic IV iodinated contrast does not require routine interruption of breastfeeding, although the evidence is limited and an informed mother may still choose a short pause.
Open set Neonatal ophthalmology · 3 minA persistent white or asymmetric red reflex is a screening failure that should trigger urgent pediatric ophthalmology assessment, even when the infant appears to see normally.
Open set Neonatal dermatology · 3 minA friction-first approach can prevent avoidable skin injury while epidermolysis bullosa is being confirmed.

Open set Neonatal gastroenterology and pharmacovigilance | 4-minute readA large contemporary cohort found invasive Bifidobacterium or Lactobacillus infection after probiotic supplementation was uncommon, but not absent. The estimate belongs inside a product- and population-specific benefit-risk discussion.
Open set Perinatal infection diagnostics | 4 min | 3 sourcesFor congenital syphilis evaluation at birth, the newborn's quantitative nontreponemal test belongs on serum and should match the maternal test type. Cord blood and neonatal treponemal testing can mislead.
