Actions of thyroid hormone

Nerve: myelination, neuronal connectionsGH production,
secretion, actionProlactin production, secretionIntestinal
glucose absorptionATP productionAdrenal medulla
activityEnzyme synthesis Stimulates BMR

Most common, treatable cause of
mental retardation
Congenital hypothyroidism

Lab values of CH

High TSH (>30)Low T4
(<10%)Important to repeat later in
premes (FPs)

Clinical presentation of Congenital
Hypothyroidism

Macroglossia
Umbilical hernia
Wide posterior fontanelle w/
open sutures
Puffy faceSlow to feed
ConstipationLethargy,
needs to be awakened to feed
Hoarse cry
Cool to

Hypotonic, slow reflexes
Prolonged
jaundice
SNHL
Increased head circumference
Weight >90%but short stature+/- palpable goiter

Thyroid Radionuclide
Uptake and Scan

most accurate test to determine type of
thyroid dysgenesis

Thyroid U/S
confirms thyroid aplasia

Serum thyroglobin
Detects amount of thyroid tissue/ thyroid activity

Treatment of
Congenital
Hypothyroidism

Levothyroxine(Synthroid) 10-15mcg/kg/day - T4 in upper range of nl during 1st
year of life to prevent retardation

DKA Lab Findings
Hypertonic dehydrationElevated serum glucose (<1000)Urinary/plasma
ketonesPseudohyponatremiaHyperkalemiaHypophosphatemiaIncreased
BUN/Cr - dehydrationLow BicarbAG Metabolic Acidosis CBC, Blood cx
(if suspect infection)

Goals of DKA treatment
1st correct dehydrationCorrect
acidosisFix elyte deficits
Correct hyperglycemia

1st step of DKA treatment
Bolus 20ml/kg (10 in newborns) NSReassess - can give
2nd bolusWill improve hyperglycemia - increased GFR
with improved renal perfusion

Potassium repletion in DKA
Depletion more evident when acidosis corrected Monitor
EKG while repleting30-40mEq/L KCl or KPhos

Phosphate repletion
in DKA Depletion becomes more evident when
acidosis correctedMonitor calcium
during repletion

Insulin tx in DKA
0.1U/kg/hr (NO BOLUS) until acidosis
(not hyperglycemia) is corrected

Dextrose tx in DKA
Add to IVF when serum
glucose <300

Diagnosis of T1DM
FPG >126OGTT/Random > 200A1C >6.5%Low insulin/cpeptideAutoAbs:
