1

HPT is the MC cause of

hypercalcemia

2

What is the MC cause of primary HPT

parathyroid adenomoa 90% of the time

3

Secondary HPT is the result of

chronic renal disease

4

Tertiary HPT is seen in

dialysis patients, happens after prolonged secondary

5

Hypercalcemia is seen in

primary
but is normal to low in 2,3

6

Parathromone stimulates

osteoclasts, which release calcium and phosphorus ions into the blood

7

Subperiosteal resorption is the most definitive radiographic sign for

HPT

8

Calcification of Big vessels is normally

age related calcification

9

Calcification of small vessels indicates

diabetes, HPT, renal failure

10

Phosphorus has an inverse relationship with

calcium

11

Hyperphosphatemia is seen with

renal failure, hypoparathyroidism

12

Hypophosphatemia is seen with

decreased intestinal absorption, increased renal excrection, HPT

13

Hypermagnesemia is seen with

dehydration, renal insufficiency, uncontrolled diabetes

14

Hypomagnesemia is seen with

malabsorption, malnutrition, alcoholism, cirrhosis

15

amylase is the most specific for

pancreatitis

16

what is the MC cause of elevated lipase

acute pancreatitis

17

Creatine Phosphokinase is specific for

cardiac muscle injury
aka CPK, CK test

18

HDL is produced where

in the liver

19

LDL's are the

bad ones, deposit into tissues associate with heart disease

20

VLDL's should be what percentage of total lipids

less than 25-50%

21

what is the most specific myocardial damage test

Cardiac Troponin test

22

Hyperparathyroidsim is due to

graves disease, toxic goiter, adenoma, pituitary tumor

23

what is the MC reason for hypothyroidism

Hasimoto's

24

Hyperthyroidism lab values are

T3,T4 elevated and decreased TSH

25

Primary Hypothyroidism values are

T3,T4 levels decreased, TSH increased

26

Secondary hypothryoidism values are

Decreased T3,T4, TSH

27

T3,T4 are regulated by

TSH, using the pituitary gland
