• Not all spinal dysphraphisms will have abnormal cutaneous manifestations that you can see on exam
• Diagnose spinal dysphraphisms with spinal ultrasound in young children and MRI in older children
• Sacral dimples can be normal but should be worked up if they are larger than 5 mm at the base, above 2.5cm from the anus, not midline, or if there are multiple dimples

Key points:

-Transplacental varicella transmission can lead to congenital varicella syndrome which includes dermatomal rash, cicatrix, limb hypoplasia, microcephaly, and cataracts

-Use Acyclovir to treat neonates and pregnant people with active varicella infection. Congenital varicella syndrome does not require treatment.

-Varicella immunoglobulin can be used to prevent infection in certain cases including exposed neonates 5 days before delivery and 2 days after delivery.

Key points:

-Most congenital syphilis is asymptomatic. Less commonly will present with rash, snuffles, hepatosplenomegaly, anemia, and jaundice.

-Untreated disease can cause neurosyphilis and bone defects

-Compare mother's RPR titers to baby's and look for findings consistent with syphilis.

-Workup is based on whether mother was adequately treated and includes CBC, LP, skeletal survey, and LFTs.

-Treatment is with IV penicillin G for 10 days.
