Medicine 1 Flashcards
3 Stages with Chronic HepB Infection with Serum Studies to Define Each
- Immune Tolerant
- HBV DNA / HBsAg +
- ALT nl, b/c no liver inflammation - Immune Active/Clearance
- HBV DNA / HBsAg +
- ALT elevated b/c liver inflammation 2/2 immune rxn - Immune Carrier
- Requires 3x nl HBV DNA AND 3x nl ALT in 12 months
HOCM Tx
Beta blockers = decrease HR = increase diastole = increase filling
Type 1 (Distal) RTA:
- Paph
- Serum K
- Urine pH
- Association / Disease
- Paph: Failure to secrete H
- Serum K: low
- Urine pH: high
- Association / Disease: Stones
Type 2 (Proximal) RTA:
- Paph
- Serum K
- Urine pH
- Association / Disease
- Paph: failure to reabsorb HCO3
- Serum K: low
- Urine pH: normal b/c acidification in distal tubule maintained
- Association / Disease: bones/fancones
Type 4 RTA:
- Paph
- Serum K
- Urine pH
- Association / Disease
- Paph: defect in Na/K tx or Aldosterone
- Serum K: high
- Urine pH: high/normal
- Association / Disease: hypoaldosterone
4 Steps in Management of Ascites
- Fluid/Na Restriction
- Spironolactone > Lasix
- Frequent Therapeutic Taps
- Peritoneal-Jugular Shunt / TIPS (Refractory Ascites)
Define Massive Hemoptysis.
Massive = ≥100c/hr or 600cc/day
What determines if CDiff is Mild/Moderate vs. Severe?
WBC >15k
Cr >1.5x baseline

Describe Eye Findings in Vitreous Hemorrhage
new onset floaters / difficult to visualize fundus / 2nd MCC - diabetic retinopathy
Describe Eye Findings in Retinal Detachment
new onset flashes of light / MCC 2/2 vitreous detachment
Describe Eye Findings in CRAO
pale optic disk, cherry red fovea, boxcar veins
Describe Eye Findings in CRVO
dilated tortutous veins, cotton wool spots, retinal hemorrhage
Describe Eye Findings in AMD
b/l progressive loss of CENTRAL vision / first sign is distortion of vertical lines
Describe Eye Findings in choroidal rupture
2/2 trauma, hemorrhage with crescenting around optic nerve
Describe Eye Findings in amaurosis fugax
pale retina 2/2 to emboli from carotids
Eye findings in Primary Open Angle Glaucoma
cupping of optic disk / “increase cup-disk ratio”
Describe Eye Findings in DM (3) + HTN (3)
DM
- Early: hard exudates, aneurysms, bleeding
- Progressive: Cotton Wool Spots
- Late: neovascularization
HTN
- Arterial Narrowing
- Cu/Silver Wiring
- Cotton Wool Spots
HSV vs. CMV Retinitis in HIV
- 1st Line Treatment for CMV retinitis
- 3x 2nd Line Rx
HSV: p/w PAINFUL vision loss 2/2 central necrosis of retina
CMV: p/w PAINLESS vision loss 2/2 fluff/granular deposits on retina with hemorrhages* (Occurs with CD4
HSV Keratitis
- Epidemiology
- Exacerbating Factor
- Eye Finding
- Tx
- vs. Zoster Opthalmitcus
- Epidemiology: MC Corneal Blindness
- Exacerbating Factor: Sun exposure (like all HSV, need stress)
- Eye Finding: Dendritic Ulcers +/- Corneal Vesicles
- Tx: Topical/PO Acyclovir
- vs. Zoster Opthalmitcus: Same eye, but zoster has rash on skin
5 Indications for Imaging in Back Pain
3 Things Causing Pain with Percussion of Back
Image Back Pain
- IVDU
- Malignancy
- Chronic Steroid Use
- Constitutional Symptoms
- New Neuro Symptoms
Percussion = Pain:
- Abscess
- Metastatic / Lytic Lesion
- Compression Fracture
Chronic Pancreatitis
- MCC
- Presentation (Triad)
- Confirmation Test
- Treatment (NBME**)
MCC = Chronic EtOHism
Presentation
- Chronic Epigastric Pain
- Steatorrhea (2/2 xExocrine Function)
- DM (2/2 xEndocrine Function)
Confirm: CT with Pancreatic Calcifications
Treatment: replace pancreatic enzymes
RA patient suddenly develops trigger finger. Paph?
Tenosynovitis of Palm
2 Patient populations with increased risk of atlanto-axial instability?
- Downs Syndrome
2. RA Patients
(T/F) Hypoalbuminemia can cause perioral numbing and Chovstek sign?
FALSE. Hypoalbuminemia can cause low TOTAL, but not low IONIZED Ca, which is what will produce these symptoms.
