2 main side effects of statins and fibrates
myositis
increased LFTs -> hepatitis
which 2 cholesterol meds have diarrhea as a SE
ezetimibe (inhibits cholesterol absorption in gut)
bile acid resins (inhibit bile acid reabsorption in gut)
it’s an osmotic effect of the unabsorbed products! can also have steatorrhea. bc fat is in stool. duh. makes sense
between troponins and CKMB which one is better for testing for MI? why?
troponins rise first and stay up longer, so this one is better UNLESS YOU’RE TESTING FOR A 2ND MI RIGHT AFTER THEY ALREADY HAD AN MI bc it’s already high from the first one. then use CKMB

- pretibial myxedema
- diagnose by Anti-TSH-R Antibody
for thyroid nodule you do TSH. what is next step if tsh is high or low?
if low -> high risk so do ultra sound and possibly FNA depending on US findings
if high -> do RAIU to see if nodule is hot or cold. hot is low risk, cold is high risk for cancer do US and possibly FNA depending on US findings

case-control: people who have disease (cases) and group who doesn’t (controls), they are investigated to see how much risk factor they were exposed to in the past. use Odds Ratio
longitudinal: theres only one group, no control group. follow the ppl with dz and see how prevalence changes over time
