Brandau Flashcards
stiffening of body and laryngospasm type seizure in child suggest what ion imbalance
Ca– tetany type
lab test with newborn seizure
electrolyte panel
glucose stick- “dextrose stick”
seizure in infant
withdrawl narcotics in mom
cerebral bleed
electrolyte
glucose
seizing infant with hypoCa
hook up IV to replenish Ca
folic acid deficiencies assoc with
neurotube defects
what Vit is important in pregnancy beside folic acid
Vit D
what vit needs to be added in breast fed infants
vit D
digeorge
22q11.2
cardiac
esophagus
thymus
how does body replensish Ca
bone resorption
metabolic defect causing cataracts
galactosemia
galactose kinase deficiency
no red reflex in child
retinoblastoma
chvostek sign
hypoCa
why check BUN Cr in hypoCa in child
make sure renal handling of Ca is okay
low Ca but high phosphorus
normal PTH
hypoPTH
dec 25, hydroxyvitD
normal 1,25 dihydroxy vit D
child
not ricketts
most likely secondary to mothers lack of Vit D prenatal vitamins
how can sepsis cause hypoCa
macrophages generated cytokines can effect PTH secretion
clinical signs hypoCa
jitteriness generalized convulsions focal seizures lethargy poor feedings
what are you looking for when do CXR for thymic shadow
catch22
stage 1 rickets
D3 deficiency
dec Ca absorption and Ca drop so PTH inc
stage 2 rickets
PO4 reabsorption dec, inc renal PO4 in kidneys
dec 25,D3
Ca maintained by PTH action on bone
predisopose to rickets
lack sunlight
lack commercial milk
anticonvulsive therapy
clinical signs vit D def
tetany
growth retardation
frontal bossing
rossary
lab findings rickets
low serum Ca low serum phosphorus high alk phos high PTH low 25,D3
hypophosphatemic rickets
genetic
auto dominant or X linked
dec Ca and phosphorus
