PEDS Flashcards
A new born with small erythematous macules/papules that become pustules on erythematous bases 3-5 days after birth
DOES NOT involve the palms or soles. Can spontaneously resolve.
Erythema Toxicum

Milia
6 or more of these increase the risk of NF1, especially if they are associated with axillary or inguinal freckling.

Nevus Simplex ( Stork Bite)
What is the difference between Port Wine Stains and Stork Bites
Port wine Stains get darker over time, can get thickening of the skin, and can be associated with Sturgeon-Weber Syndrome,
All things that Nevus Simplex’s/ Stork bites do not.
Staph Scalded Skin Syndrome is most common in what age group
Infants (3-7 days of age) or children less than 5 yo

A pt presents with prominent epicanthal folds, Brushfield spots (while spots on the iris), transverse palma crease, and AV defects (tet of fallot)
Trisomy 21
Abnormally high or low beta-hCG in a neonatal testing can indicate what genetic abNMality
