how do you treat a pt who has OD’ed on beta blockers

glucagon> increases HR and contractility independent of adrenergic receptors

Perfectly

why can glucagon be used to tx a beta blocker overdose?

activates GPCR on cardiac myocytes>
activation of AC>
raises intracellular cAMP>

L and R common iliac veins

what happens hwen ATP binds myosin

release of myosin haead from binding site on actin filament

what causes renal osteodystrophy

end stage renal diseaes>
hypocalcemia and decreased phosphate excretion and decreased renal synth of vit D

*hypocalcemia nad hyperPTH contribute to renal osteodystrophy

How has acute RF been reduced in industrialized nations

tx s. pharyngitis w/ antibiotics

acute acalculous cholecysitisis

acute inflammation of GB in abscence of gallstones (often occurs secondary to GB stasis and ischemia) *commonly seen in hospitalized and very ill

What is shown to SLOW the progression of HF and reduce all cause mortality in pts w/ CHF

Beta blockers slow ventricular rate and decrease afterload

What is specifically used to tx pts w/ HF and CHF?

Carvedilol antagonizes B1/B2 and alpha 1

loop diuretic used to tx HF assoc w/ peripheral edema

furosemide/ loop diuretics

used to tx supraventricular and ventricular arrhtymias

amiodorone

PDE inhibitor that increases cardiac contractility and decreases preload and afterload

milrinone

improves morbidity but not mortality in pts w/ CHF

digoxin

how do you dx acute cholecystiitis?

often cuased by gallstones obstructing cystic duct identify signs of GB inflammation

how do you dx acute cholecystiitis?

often cuased by gallstones obstructing cystic duct identify signs of GB inflammation using US

what do you do if US is inconclusive for acute cholecystitis?

NM scan can be used to detect it w/ a radiotracter. GB won't be visulaized d/t obstruction

what causes drug induced parkinsonism

D2 receptor blockers Antipsychotics (first generation) Antiemetics

how do you tx drug induced parkinsonism

benzotropine (antimuscarnic) | amantadine (increass Da release and prevents reuptake)

what is contraindicated for anti-psychotic induced parkinsonism b/c they can preceipitate psychosis

levodopa and | Da agonists

tinnitus vertigo sensorineural hearing loss d/t increased volume and pressure of endolymph in hte vestibular apparatus

Menieres disease

leads to formation of an annular pancreas

abnormal migration of ventral pancreatic bud *encircles descending part of duodenum> lead to sxs of duodenal obstruction in neonates

leads to formation of an annular pancreas

abnormal migration of ventral pancreatic bud *encircles descending part of duodenum> lead to sxs of duodenal obstruction in neonates

what is the pancreas derived from

foregut

pathogenesis of Wilsons disease

excess of non-ceruloplasmin bound serum copper> | leads to injurious accumulation of this element in the liver, CNS, lenticular nucleus, cornea

tx for Wilsons disease

chelation therapy w/ penicillamine to remove excess losely bound serum copper

chelating agents used to tx lead poisoning

Dimercaprol | EDTA

used to tx cirrhosis related hepatic encephalopathy

lactulose

Deferoxxamine

tx hemochromatosis | Fe chelating agent

characteristics of intravascular hemolytic anemias

shistocytes d/t fragmented RBC> decreased haptoglobin increased LDH and bilirubin

decreased haptoglobin

haptoglobin binds FREE Hb and is indicative of hemolysis

gliosis

proliferation of astrocytes in area of neuron degeneration> leads to formation of glial scar which compensates for volum loss after neuronal death
