Amiodarone sfx and how to monitor
Pulmonary toxicity - interstitial pneumonitis, ARDS
Obtain CXR and PFTs at baseline
S4 indicates
stiff/hypertrophied ventricle
DDX
- acute MI
- HTN
- aortic stenosis
- hypertrophic cardiomyopathy
rheumatic heart disease murmur
mitral stenosis
aortic stenosis
what should you avoid giving someone on cocaine?
beta blocker
aortic dissection treatment/management
1) pain control
2) beta blocker
3) Na nitroprusside
Dihydropyridine Calcium Channel Blocker sfx
and how to reduce it
sfx = peripheral edema
treatment = ACEi/ARB
What should be avoided in treatment of an Acute MI that becomes Flash Pulmonary Edema?
Avoid beta blockers in the presence of flash pulmonary edema
Tx =
- ASA, Clopidogrel
- Statin
- Loop diuretic
EKG:
High voltage QRS
Lateral (v5-v6) ST depression
Lateral (v5-v6) T inversions
LVH
Treatment of beta blocker overdose
presentation = bradycardia, hypotension, AV block, diffuse wheezing, seizures, cardiogenic shock
treatment =
1) Airway
2) Isotonic fluid bolus
3) IV atropine (to fix bradycardia and hypotension)
4) IV glucagon
Nitroprusside sfx
Cyanide toxicity
- occurs when pt is receives high doses or if someone has renal failure (elevated Cr)
- symptoms = AMS, lactic acidosis, seizures, coma
When do you give IVIG for tetanus prophylaxis?
If un-immunized or received <3 toxoid doses or patient unsure AND large/dirty wound
What is the CD4 cut off for receiving live vaccines?
Patients with CD4<200 should not receive live vaccines
- MMR
- VZV
- oral polio
- nasal influenza
- rotavirus
- yellow fever
Malaria prophylaxis
- Mefloquine - starts before, throughought ends after return
- Atorvaqone-Proguanil
- Doxycyline
Osteomyelitis - which two bacteria?
Staph aureus
Pseudomonas
Young + HTN + Diuretic-induced hypokalemia
Primary hyperaldosteronism (Conn)
Polydipsia + Polyuria DDX (5)
- DM
- Diuretic use
- Central DI (serum Na elevated)
- Nephrogenic DI (serum Na normal)
- Primary polydipsia (serum Na low)
What does a positive Prussian blue stain indicate?
positive hemosiderin (indicates hemolysis)
cirrhosis + ascites + low grade fever + abdominal discomfort + altered mental status =
tx
SBP
-fluid is positive if there are >250 PMNs or >500 WBCs
tx = IV Abx
-3rd generation cephalosporins to cover gram negative (EColi, Klebsiella) and gram positive (Enterococcus)
What does OCP induced liver damage look like in lab and biopsy
Lab = abnormal LFTs
Biopsy = no evidence of necrosis or fatty changes
IgA Nephropathy vs Post-Streptococcal Nephropathy
IgA Nephropathy = 5 days post-URI, normal compliment
Post-Streptococcal Nephropathy = 10-14 days post-URI/pharyngitis, low compliment (C3)
What lab value indicates saline responsive metabolic alkalosis?
What lab value indicates saline resistant metabolic alkalosis?
Saline responsive: urine Cl <20
tx = NS MIVF + K
Saline resistant: urine Cl >20
tx = spironolactone
COPD treatment with maximal impact on mortality
- smoking cessation
- home O2
Treatment of an acute exacerbation of COPD (5)
- O2 (target SpO2 88-92%)
- inhaled bronchodilators
- systemic glucocorticoids
- antibiotics (if there are >2 symptoms)
- NPPV if respiratory failure
woman + chronic dry cough + malaise + bilateral hilar lymphadenopathy =
Sarcoidosis (Chronic Granulomatous Inflammation)
