What kind of hernia can you see in congenital hypothyroid
Umbilical
What lipid abnormalities can you see in hypothyroid
High ldl
High tgs
In asymptomatic hypothyroid treat with levothyroxine if tsh is above
10 mU/L
Increased serum alk phos level with normal ggt level points to what etiology
Bone, not liver
Bone pain and hearing loss, think
Paget’s disease
Low serum phosphorus feedback loop
Low serum phosphorus converts 25 vit D to 1,25 vit D, which causes release of phosphate from bone matrix and increased intestinal reabsorption
Lab values in paget dz of bone (alk phos, calcium, phosphate)
High serum alk phos, normal calcium and phosphate
Pth works on what two organs to increase calcium
Renal tubular cells to reabsorb calcium and bone to stimulate calcium release
Parathyroid hormone stimulates production of 1,25 vit d, which causes calcium reabsorption from the
Gut
Stones, bones, moans, groans and psychic overtones indicate what
Hypercalcemia
Tx of hypercalcemia
Fluids then loop diuretics and iv bisphosphonate
Pth ___ phosphorus
Decreased

Hyper
Hypo
Hyper
In secondary hyperparathyroidism, If etiology is renal failure what is phosphate level
High
What is familial hypocalciuric hypercalcemia
Inherited disorder due to mutations in calcium sensing receptor present in parathyroid and kidney. Have normal pth, hypercalcemia and hypocalciuria. Asymptomatic and no tx necessary
What is cinacalcet
Lowers serum pth levels and is used for hyperparathyroidism due to pts with renal failure or who can’t undergo surgery
What is Sheehan syndrome
Pituitary infarction secondary to postpartum hemorrhage
Most common cause of Cushing syndrome
Prolonged tx with exogenous corticosteroids
Difference between Cushing syndrome and Cushing diseAse
Syndrome: too much cortisol
Disease: too much cortisol from acth producing pit adenoma
Dx of Cushing syndrome
Dexamethasone suppression of plasma cortisol, or measure 24h urinary free cortisol
How to determine if Cushing syndrome is due to adrenal tumor or acth dependent Cushing syndrome
Measure plasma acth and cortisol after dexamethasone suppression test. If acth is suppressed, it’s an adrenal tumor
