correct detailed answers latest update 2025
what are some symptoms of mitral valve prolapse syndrome? ---
correct answer ---various nonspecific symptoms such as palpitations,
dyspnea, exercise intolerance, anxiety disorders, and dizziness
since symptoms are relatively uncommon, what physical exam
findings are associated with mitral valve prolapse? --- correct answer
---non-ejection click in systole
click is mobile, meaning its timing varies with maneuvers that change
the left ventricular volume, occurring earlier in systole with sitting,
standing, or other interventions that reduce ventricular size, or later
with those interventions that increase chamber size such as squatting
People with MVP tend to have lower BMIs
how would you distinguish vasospastic angina and angina associated
with CAD? --- correct answer ---quality of the CP is typically
indistinguishable of the two
,patients with vasospastic angina report that their episodes are
predominantly at rest and that many occur from midnight to early
morning, while effort tolerance is usually preserved. CP generally
lasts 5 to 15 minutes
Patients with vasospastic angina are often younger and exhibit fewer
classic cardiovascular risk factors and may be associated with other
vasospastic disorders, such as Raynaud's phenomenon and migraine
headache
Exercise does not usually provoke an episode of spasm
ECG may reveal transient ST-segment elevation or depression in
multiple lead but troponins will not be elevated
where do karposi sarcoma lesions typically occur? describe their
appearance. --- correct answer ---often on distal extremities, such as
lower legs and feet
purplish, reddish blue, or dark brown/black macules, plaques, and
nodules on the skin. Nodular lesions may ulcerate and bleed easily
,common in poorly controlled HIV
how would you treat hidradenitis suppurativa? --- correct answer ---
topical clindamycin
if fail topical therapy, oral tetracyclines are suggested
Antiandrogenic drugs and metformin are additional treatment options
that may be used alone or in conjunction with antibiotic therapy
Pt with hypertriglyceridemia >885 mg/dL that required medical
therapy due to no improvement after lifestyle changes and statin. how
would you treat? --- correct answer ---fenofibrate
fenofibrate is better than gemfibrozil bc can be used with a statin.
Gemfibrozil has a higher risk of muscle toxicity
how would you initially treat a pt with hypertriglyceridemia? ---
correct answer ---lifestyle changes (reduce EtOH consumption,
aerobic exercise, better glycemic control) and statin
, what causes subacute thyroiditis? --- correct answer ---presumed to
be caused by a viral infection or a postviral inflammatory process.
Many patients have a history of an upper respiratory infection prior to
the onset of thyroiditis
seasonal incidence (higher in summer)
Large-needle thyroid biopsies reveal widespread infiltration with
neutrophils, lymphocytes, histiocytes and giant cells, disruption and
collapse of thyroid follicles, and necrosis of thyroid follicular cells
how is the diagnosis of subacute thyroiditis made? --- correct answer
---clinical dx
neck pain, thyroid tenderness
suppressed TSH
T3/T4 mildly elevated
if clinical dx is not certain, US can be used to distinguish subacute
from Graves. Graves has increased flow and subacute has decreased
flow. FNA rarely needed/used
