Q
  1. (Picture of a baby with an elongated skull in AP diameter). Mother brings in her baby with concerns regarding the shape of his head. What should you consider? On exam, what do you look for to confirm?
A

A. Craniosynostosis vs plagiocephaly

  • Scaphocephaly/dolichocephaly - premature fusion of sagittal suture (50% of craniosynostosis)
  • sutures: metopic, coronal, sagittal, lambdoid

B. O/E
- Palpate for overriding sutures
- premature closing of anterior fontanelle
- look at shape of head from above - frontal bossing + ear displacement
- measure occipital-frontal circumference (normal in craniosynostosis)
- measure biparietal diameter (reduced)
(parallelogram with ipsilateral frontal bossing + ipsilateral ear anterior suggests plagiocephaly
vs trapezoid with contralateral frontal bossing + ipsilateral ear posterior suggests lambdoid craniosynostosis)

C. Imaging

  • Plain x-ray
  • CT to further characterize

D. Assoc’d conditions with craniosynostosis

  1. Hypophosphatemia
  2. Rickets
  3. Syndromes (crouzon, carpenters)

Q
  1. Mom with no prenatal care gives birth to kid with anencephaly. She asks if the kid’s organs (heart, kidneys) could be donated. What answer do you give her (1 point)? Why (1 point)?
A

The policies of the Canadian Paediatric Society (1990, reaffirmed in 2005) and of the American Academy of Pediatrics (1992) stated that anencephalic infants were not appropriate organ donors, and held firm to the prevailing legal and medical criteria for brain death.[6] The AMA changed course, and its current policy now also affirms the “dead donor rule,” but it does allow mechanical support to keep the organs viable until death is declared

22

  1. Calcium infusion (PO calcium takes too long to work)
  2. Vit D (allows gut to absorb calcium, which is caused by vit D deficiency secondary to PTH)
23
Q
  1. Neonate with glucose of 0.9. Not interested in feeding. You decide to treat & give a 2cc/kg bolus of D10W. Write your orders for fluids to run next (be specific.)

Check glucose in 30min

24

    b) Same baby does well for 48hrs then becomes mottled with poor BP and new gas: pH 7.1, CO2 40, base deficit really high, Hct 0.3. What has happened?
A

a) Increase rate (if not breathing above) or increase VG (ensure 4-6mL/kg) or PIP
