Q

What does PTH do to phosphorous levels:

A

PTH has a phosphorus-lowering effect by causing phos excretion through the kidneys.

(so in hypoparathyroidism, where PTH is low, phos will be HIGH)

Q

What does PTH do to vitamin D levels

A

PTH stimulates the kidney to make active vitamin D, so PTH increases vitamin D levels

this is how PTH increases Ca absorption from the gut (through vit D, which does this)

Q

Long term tx for hypoparathyroidism

A

Q

What does vitamin D deficiency do to calcium and phos levels

A

both low

(low calcium means PTH is being very active trying to raise the calcium, and while being active one of the things PTH does is promote renal excretion of phos, so phos gets low)

Are topical antifungals effective when treating tinea capitus

Nope. Because tinea capitus is an infection of the root of the hair follicle, so topical tx does not work. Need systmic oral antifungal tx.

Get GONADOTROPIN LEVELS (FSH and LH)

If they are high, then you know the pt has hypergonadotropic hypogonadism, and you should start estrogen treatment to induce puberty

74
Q

How to induce puberty in a girl with Turner Syndrome who has hypergonadotropic hypogonadism:

Give estrogen
but start in low doses, and then gradually work up to what would be an adult dose (aka like a birth control pill) to try to mimic normal puberty

A

complete heart block

87
Q

Transplacental transfer of these antibodies leads to neonatal Lupus

A

anti-Ro/SSA or anti-La/SSB
