3 Transplant Rejection
- Timing
- Paph
- Tx
- Hyperacute
- Timing: minutes
- Paph: pre-formed antibodies –> vascular occlusion –> ischemic/necrosis - Acute
- Timing: weeks-months
- Paph: Host CTL against graft –> perivascular lymphocytic vasculitis
- Tx: Immunosuppresion/steroids - Chronic
- Timing: months-years
- Paph: non-self MHC are viewed by host CTLs as self MHCs presenting foreign peptides —> Fibrosis
- Tx: none, irreversible
Charcot Joint
- MCC (2)
- Paph
- XRay Findings (3)
- Management
- MCC (2) = DM + B12
- Paph: xProtopathic/epicritic –> increase trauma
- XRay Findings (3): effusion, osteophytes, loose fragments

- Paph
- Tx
Criteria
- Temp >104 (40)
- Collapse
- CNS Dysfunction
- End Organ Damage (ARF, Rhabdo, Nose Bleeds)
Paph: elevated central temperature = inability of hypothalamus to regulate body cooling
Tx = rapid cooling with ice water immersion
(T/F) In Sheehan’s postpatum necrosis:
- Aldosterone level is low
- Na is low, K is high
FALSE; recall the zona glomerulosa is ACTH independent (AngII dependent).
Bottom Line: primary adrenal failure = xAldosterone, but secondary adrenal failure = normal Aldosterone
Paph of Malignant Hyperthermia
Autosomal dominant inheritance of abnormal Ca cells in myocytes; increase risk with halothane/succinylcholine
Patient with primary hyperAldo is given spironolactone for control of aldosterone. Develops gynecomastia. Next step?
Switch to eplerenone (selective mineralocorticoid antagonist)
Tx of Warm (3) vs. Cold (1) AIHA
Warm: steroids –> rituximab –> splenectomy
Cold: warm them!
Describe Heinz bodies. When should you measure G6PD enzyme activity level in a symptomatic patient?
Heinz Bodies = ferrous –> ferric state
G6PD levels in ACUTE attack are NORMAL b/c all the abnormal RBC are hemolyzed; measure 120 days later
MCC risk factor for aortic dissection?
Systemic HTN
Rx approved for treatment + prophylaxis of secondary amyloidosis?
Colchicine
Acromegaly
- Screening Test
- Diagnostic Test

Bisphosphonate
ABx (Doxy)
NSAID
Supplements (KCl, Fe)
Patient with signs of hyperthyroidism has non palpable thyroid. Next step? Confirmatory test for exogenous vs. thyroiditis?
next step = radioactive uptake (if low = DDx Exogenous vs. Thyroiditis)
- thyroiditis = increase thyroglobulin in serum b/c damaged cells
- exogenous = low throgobulin
Next best step in patient with progressive proximal muscle pain / weakness. CPK is elevated?
TSH
Diagnostic test in lactose intolerance?
H+ Breath Test
- Lactose = increase lactic acid in GI tract = increase H+ out
Osteosclerosis
- 2 Populations
- Rinne + Weber Tests
Populations = AI process in mid-age women vs. Paget’s disease
Rinne Test: AC
Tick-borne Paralysis
- P/w
- Next best step
P/w: ASYMMETRIC ascending paralysis (≠GBS, no prodrome); occurs 2/2 neurotoxin released from tic
Next step = find tick, it goes away
Factorial Design Study Defintion
≥2 experimental interventions (3 different anti-HTN Rx)
AND
≥2 end points (SBP and serum K)
Rx Indicated and Contraindicated in Prinzmetals

Trichinosis: Bug, Transmission, 3 Phases (with Triad in 3rd Phase)
Bug = Trichinella (roundworm vs. Cystercercosis/Taeina = pork tapework) Tx = Eating undercooked pork (vs. Cyster = eating eggs in poop)
Phases
- Larva enter GI tract (GI complaints)
- Larva Migration (Systemic Hypersensitivity) = Splinter Hemorrhage
- Larva Enter Skeletal Muscle = Triad of All Phases
* Myositis
* Periorbital Edema
* Eosinophilia
(Don’t confuse with taenea solium = cystercisosis)

- CD4
(T/F) A negative FOBT at visit excludes GI bleed.
FALSE, still get a colonoscopy if it’s an older ANEMIC person.
Patient with inferior MI infarct is started on Nitro drip. Found to be hypotensive. Next 2 steps?**
- Stop NITRO (CI in RV MI, Aortic Stenosis, PDE-I use)
- Start IVF
**Recall, IVF are the mainstay of RV Infarct management b/c the body is preload dependent
When to start DM screening?
ADA recommends @45 in asymptomatic patients***

- Adequate Bystandard CPR
- Prompt Rhythm Analysis
- Defibrillation
NOT time to cath lab
MC Complication of Radiactive I131 for Grave’s?
HYPOTHYROIDISM (not worsening of optho or hypoPTH (surgery))
Note, corticosteroids before and after RI131 can decrease optho consequences
AEIOU Indications for Dialysis
- Acidosis (refractory metabolic acidosis
HOCM murmur increases on intensity with _______ and decreases on intensity with ________. What other murmur does this and why?
HOCM increases with valsalva (decrease VR = decrease LVEDV = increase obstruction) and decreases with squatting (increase afterload = increase LVEDP/distention)
MVP does the same
- decrease VR = decrease LVEDV/distention = decrease strain on chorda tendinae = easier to prolapse
- increase VR = increase LVEDV/distention = increase strain on chorda tendinae = hard to prolapse, keeps valve shut
