Step 3 Flashcards
What conditions make angiodysplasias more likely to bleed?
ESRD (uremia), Aortic stenosis (shearing of vWF), and vWD (nonfunctional vWF)
What medications should you avoid in Lewy Body dementia
Antipyschotics
=» Worsening confusion, parkinsonism, and autonomic dysfnxn
Pt who gets cardiac catheterization and develops tachycardia, HTN, sweating
Iodine-induced hyperthyroidism
-Tx w/ BB, methimazole if no resolution
Tick paralysis
Caused by Dermacentor species
CFs: Fatigue, gait ataxia, ascending paralysis
***ALL OVER THE COURSE OF A FEW HOURS
Population Attributable Risk (PARP)
(Risk in total pop- Risk in unexposed)/ Risk in total pop
Complex Regional Pain Syndrome
Pain occurring out of proportion to extremity injury; associated w/ temperature change, edema, and change in skin color
-Likely due to injury to sympathetic nerves =» allodynia
Stage I: Burning pain, edema, vasomotor changes
II: Progression of above + skin thickening + muscle wasting
III: Limited ROM + bone demineralization on XR
Tx: Regional sympathetic nerve block
Tx for choroidal melanoma
Radiotherapy
Preferred antiarrythymic in CHF patients
Amiodarone
Hyperviscosity Syndrome
Nasal/oral bleeding, blurry vision, confusion, headache, heart failure
-Seen in MM, Waldenstrom’s
Tx: Plasmapharesis
Reasons to use dobutamine over milrinone
Specific B-agonist that increases cardiac contractility
- Given when CVO2 is decreased
- Also good when AKI present as it is not nephrotoxic
Corrected Calcium
Ca + [Ca + 0.8(4-albumin)]
First test in any patient w/ hypercalcemia
PTH
Periodic breathing
Physiologic breathing pattern in infants up to 6 months old characterized by pauses 5-10 seconds long followed by rapid and shallow breaths
Though to be due to immaturity of the nervous system and is caused by central apnea
Should resolve spontaneously
Negative sputum for PCP in untreated HIV Pt
PCP IS STILL #1 DIAGNOSIS
When to use steroids in patient w/ PCP
When A-a gradient is >35mmHg on RA
or
When PaO2 <70mmHg on RA
