Test 91 Flashcards
common complication of varicose veins
venous stasis ulcers around the medial malleoulus
assymetric ventriular septal hypertrophpy and variable dynamic left ventircular outflow tract obstruction
Hypertrophic cardiomyopathy
lead to increaed murmur intesnsity in hypertrophic cardiomyopathy
Decreasing preload/afterload reduces LV chamber size, decreasing the separation between the mtiral valalve and the IV septum, increasing obstruction
sudden standing, vasalva (strain phase), Nitro
squatting
sustained hand grip
passive leg raise
increase preload/afterload> DECREASE LVOT murmur intesnsity
MC cause of death in pts w/ diptheria infection
cardiomyopathy
Tx for diptehria
diptheria antitoxin (passive immunization)**most impt and has greastest effect on prognosis, Abx, active immunizatin
acute obstruction of small airways in infants
secondary to RSV bronichiolitis
Ribavarin
antiviral drug that may benefit in RSV bronchiolitis
Oseltamiviv
sialic acid analogue inhibiotr of influenza A and B viral neuraminidases
Ganciclovir
anti-herlpesvirus guanine nucleoside analong
CMV
Amantadine
imapir unocating of influenza A virion after host cell endocytosis
early onset pericarditis
inflammatory rxn to cardiac muscle necrosis adjacent to visceral and parietal pericardium
dresslers syndorme
autoimmune polyserositis
two major RFs for developing ARDS
sepsis and shock
lung finding associated w/ ARDS
intra alveolar eddema and alveolar hylaine membranes
wedge shaped pleural based infarctions in lung w/ hemorrhagic necrosis
PE
highly selective proteinuria
mostly low moceuar weight proteins, albumin/transferrin
c-myc
burkitt lymphoma
n-myc
neuroblastoma
small cell carcinoma of lung
BCR-ABL
CML> increased TK activity
BCL-2 overexpression
follicular lympohoma
caues sxs of septic shock and cahcexia at high concentrations
TNFa
episodic, transient attacks of coronary vasospasm at rest during middle of night to early AM hours
prinzemetals angina
temporaory transmural myocardial ischemia w/ ST elevation
can provoke coronary vasospasm and aid in dx
ERgonovine
Tx of prinzmentals
vasodilating nitrates
Ca channel blockers
Phentolamine
a1 and a2 antagonist> vasodilate
amlodipine
ca channel blocker> vasodilate
morphine
vasodilaor
rapid correction of hyponatremia
osmotic demyelination of axons
rapid correction of hkypernatremia
cerebral edema
carpopedal spasms
hypocalcemia
arnold chiari malformations
congenital abnormality
impaired devo of posterior fossa
LG ion channels that OPEN after binding ACh
> influx of Na/Ca and outflux of K from cell
Nicotinic receptors
EPI to A1 receptor
IP3 pathway> increase in intracellular Ca
B1, B2 recetpors
cAMP> PKA activation
M1 and M3
ITP> increased Ca and activate PKC
Li Fraumeni syndrome
AD predisposition to variety of cancers
sarcomas, tumors of breast, brain and adrenal cortex are MOST common
