- Cherry macula
- Blood & Thunder
- Flame hemorrhages & papilledema
- CRAO
- CRVO
- HTN emergency
Thyroid Storm tx
TIC-B Thionamide (PTU or Methimazole) - decr production Iodine - neg feedback Corticosteroids - stop T4 to T3 B-blockers
Scorpion toxicity
oral secretions
muscle jerking
wandering eyes (opsoclonus)
Black widow toxicity
alpha toxin (norepi) - HTN and tachy
Brown Recluse
Necrotic skin, hemolysis (DIC)
von Willebrand dz
Dysfunctional plt adhesion
Tx: factor VIII (similar to hemophilia A)
Infant weakness/paralysis w/ preserved deep tendon reflexes
Infant botulism
Pemphigus vulgaris
Elderly skin & mucosal blisters - FLACCID w/ +Nikolsky
Bullous pemphigoid
elderly skin blisters - TENSE, – Nikolsky
Gen. edema, protinuria, low albumin, high cholesterol
– Thrombophilic (hypercoagable)
Nephrotic Syndrome
Differentiate Anticholinergic and Sympathomimetic
DRY vs WET skin
(both hot, dilated, delirious
Anticholinergic toxidrome
delirium, DRY, flushed, hot, dilated
2/2: atropine, diphenhydramine, antipsych, jimson weed
Sympathmomimetic toxidrome
WET, hot, dilated
2/2: PCP, cocaine, ecstacy, meth
Infectious liver abscess (southwest)
Entamoeba histolytica (tx: IV metronidazole)
GI complication of HSP
Intussesseption
ABI (ankle-brachial index)
SBP of DP / SBP of arm
>0.9 is normal,
<0.5 severe impairment of flo
Tx of HTN emergency
Lower by 25% over 1 hour and to 160/110 over the next 6 hours
LBBB on EKG
QRS > 120
V1 & V2 - broad and deep S wave
V5 &V6 - broad and clumsy notched R wave
RBBB on EKG
QRS > 120
V1 & V2 - RSR’ (‘M’)
STEMI on ECG
- > 1 box elevation in 2 contiguous leads
- New LBBB
- reciprocal changes = worse prognosis
(historically there should be 1.5 or > elevation in V2/V3)
Stye (hordeolum) vs Chalazion
Hordeolum - lashline
Chalazion - eyelid
Pacemaker undersensing & oversensing
inappropriate pacer spikes (under) not enough pacing / syncope (over)
Wet/Dry Beriberi
Thiamine (B1) Deficiency
- Wet = CHF w/ dyspnea & pulm edema
- Dry = Neuro w/ AMS, ataxia (Wernicke-Korsakoff)
High CO heart failure
Anemia
Thyrotoxicosis
AV Fistula
Beriberi
SIADH
Lung Cx
- inapproprate salt wasting
- tx: fluid restriction
Acute Porphyia
Increased heme
- psychosis and abdominal pain
Wilson’s Disease
increased copper (decr ceruloplasmin)
- change in personality
- tremor/ataxia
- K-Fleischer ringxs
von Willebrand disease Tx
Factor VIII is the treatment for bleeding (25-50 U/kg)
Tumor Lysis Syndrome
HyperK HyperPhos HyperUremia HypoCa Acute renal failure
Platelet transfusion level with acute bleeding
<50,000
Hemophilia A replacement
Factor VIII
- 25 u/kg moderate injury
- 50 u/kg severe injury
TTP pentad
F - fever A- anemia (hemolytic, schistocytes) T- thrombocytopenia R- renal failure N- Neuro (AMS) -- Tx: plasma exchange
DIC labs
Low platelets and fibrogen
Elevated PTT, PT, INR, dimer
Virchow node
Supraclavicular lymph node in peds and adults that signifies intraabdominal cancer
Guillain-Barre
- Miller-Fisher varient
Ascending paralysis, areflexia
- MFV = ophthalmoplegia
Methanol
Ethylene glycol
Isopropanol
M - blindness, formeldhyde, folic acid
EG - CaOx crystals, fluoresent urine
Iso - Osm gap but NO AGAP (acetone)
“OK” sign strength tests which nerve
Median
Centripetal Rashes
(move centrally - extremities to trunk)
- RMSF, syphilis, dengue, Kaposi, coxsakie
Digoxin toxicity tx rules (2)
- AVOID using calcium to treat hyperK, “stone heart”
- arrhythmia are treated with Fab NOT electricity
