UWORLD random 3/20a Flashcards
parietal cell epi location
upper glandular layer
below simple columnar epi cells that secrete mucus
calcineurin
activates NFAT –> NFAT binds IL-2 promotor in nucleus –> ++ IL-2
IL-2 stimulates growth and differentiation of T cells
calcineurin inhibitors
cyclosporine
tacrolimus
vit C deficiency sc
easy bruising mucosal bleeding periodontal disease poor wound healing hyperkaratotic follicles with corkscrew airs
scurvy
Vit C deficiency pathophys
impaired hydroxylation of proline and lysine residues during collagen synthesis
IL-12
on macrophage
stimulate T-cell differentiation into TH1 subset
IL-12 deficiency
no activation of macrophages for intracellular organisms (mycobacteria)
tx IFN-y (bypass IL-12)
post strep A complications - preventable with AB?
assoc with skin infxn?
PSGN - not preventable by AB
acute rheumatic fever - preventable
NOT after skin infections
multiple myeloma
normocytic, normochromic anemia
infiltration of bone marrow by plasma cells
IL-1, IL-6 activate osteoclasts –> bone resorption, osteopenia
hypercalcemia
hyperimmunoglobulinemia
AL amyloid
renal failure
head bobbing with carotid pulsations
large LV stroke volume to head and neck
aortic regurg
bounding femoral/carotid pulses
wide pulse pressure
aortic regurg
aorti regurg murmur
diastolic decrescendo murmur L sternal border
mycoplasma & anemia
complement mediated intravascualr anemia
similar antigens to cell membrane of M pneumo and erythrocytes
genetic shift
influenza A
rotavirus
segmented genome
normal FEV1/FVC
80%
tolerance to opioid side effects does NOT include
constipation
Cheyne-Stokes breathing
CHF
cyclic breathing pattern
apnea - gradually increasing and decreasing tidal volumes - apnea
poor prognostic sign
location of thoracentesis
b/t 6-8 ribs along midclavicular line
8-10 midaxillary line
10-12 paravertebral line
above = hit lung below = hit liver/abdominal structures
familial dyslipidemias (I-IV)
I chylomicronemia (LPL, ApoCII -- chylomicrons) II hypercholesterolemia (LDL-r, ApoB100 -- LDL) III dysbetalipoproteinemia (ApoE -- chylomicron, VLDL remnants) IV hypertriglyceridemia (ApoA-V - VLDL)
familial dyslipidemia complications
I,IV = pancreatitis
I, II, III = xanthomas
II, III = premature CAD
transesophageal echo - closest structure
anterior?
posterior?
ant = left atrium
post = desc aorta
tx adrenal crisis
hydrocortisone
dexamethasone
active Ras
GTP
activate MAPK
neprilysin
metalloprotrease that inactivates peptide hormones
bradykinin, glucagon, enkephalins, natriuretic peptids
