Test 70 Flashcards
leading cause of cancer mortality in women
lung cancer
increased cigarette smoking
IL-2
stimulates grwoth of CD4 adn CD8 and B cells
also activates NK cells and monocytes (anti-cancer effect on metastatic melanoma and arenal cell carcinoma)
uniform thickening of the ventricular wall and narrowing of the ventrcicular cavity
concentric hypertrophy
seen w/ increased afterload
dilation of ventricle w/ associated increase in chamber size
volume overload
thalamic syndrome
total sensory loss on CONTRALATERAL side of hte body
*no motor deficits
lesion of internal capsule
motor deficit
ischemic event of the pons
coma bilateral paralysis cerecbrate rigidity pinpoint pupils death
small 5 mm cavities in hte basal ganglia, osterior limb of internal capsule, pons aand cerebellum are known as…
lacunar infarctions
d/t occlusion of small penetrating arteries in settin gof HTN or DM
small vessel lipohyalinosis and atherosclerosis
leads to lacunar infarctions
oligodendrocyte apoptosis
occurs in MS> demyelinating disease of CNS
loss of atrail contraction d/t a. fib
reduce LV preload and CO and can cause systemic hypotension
meconim ileus
specific for CF
accounts for 80% of eventual deaths d/t CF
tx resistant infectious pneumonias
bronchiectasis
cor pulmonale
fantasy
immature defense mechanism
substitutes imaginary, less distrubing view of world to avoid awareness of painful feelings
denial
refuse to acknoweldge a painful reality

strep bovis
phenoxybenzamine
irreversible A1 and A2 adrenergic antagonist
HIGH conc of NE can overcome effect
Acyclovir
valacyclovir
famciclovir
ganciclovir
nucleoside analogues that require both herpes viral and cellular kinases for conversion to active nucleoside triphosphate form
cidofovir
tenofovir
nucleoTide monophosphate
requires ONLY cellular kinases fora ctivation
cell dep nucleosides
zidovudine
lamivudine
drug induced lupus
linked to drugs that aremetabolized by N acetylation in the liver
(hydralazine, procainamide)
nitroprusside
short acting
venousa nd arterial VASODILATOR that decreass both preload and afterload
produces eggg shell calcifications of hilar nodes and birefringent particles surrounded by fibrous tissues

assoc. w? thymoma
lymphocytic leukemias
parvo B19
coadministartion of SSRIsa nd MAO inhbitors
can produce excessive synaptic 5HT levels secondary to decreased reuptake and decrased degradation> 5HT syndrome
