Pediatric Case Answers!

Answers from the cases in the prior post...

Pediatric Case 1: Answer = C
At 6 to 6.5 months of age, infants will be able to site along, leaning forward to support themselves with arms extended, in the so-called tripod position. They can reach for an object by changing the orientation of the torso. They can roll (on purpose) from prone to supine and visa versa. By 12 months, they can grasp a pellet between their thumb and forefinger w/out ulnar support. Motor development goes cephalo-caudal and central to peripheral - in other words, the babies can control their trunk before they can control finger dexterity.

Pediatric Case 2: Answer = D
Chlamydiae, sexually transmitted in adults, is spread to infants during birth from the genitally infected moms. The sites of infection in infants are the conjunctivae and the lungs, where chlamydiae cause inclusion conjunctivitis and afebrile pneumonia (usually in infants 2-12 wks). Diagnosis is confirmed by culture of secretions and by antibody titers. **Note: most common tx for this is macrolide antibx orally which clears both the nasopharyngeal secretions when a conjunctivitis is present and prevents the pneumonia that can occur later. Topical tx is not effective in clearing nasopharynx.

I'll try to throw out some more cases here and there... Thanks for the guesses!
