|
What are the epithelial cells of the Ovary?
|
Simple Cuboidal (aka germinal)
|
|
|
What are the epithelial cells of the Fallopian tube?
|
Simple CoLumnar (CiLiated)
(faLLopian) Have Peg Cells to secrete nutrients |
|
|
What are the epithelial cells of the Uterus?
|
Simple pse-U-dostratified col-U-mnar
t-U-b-U-lar glands |
|
|
What are the epithelial cells of the Cervix?
|
Endo = simple columnar
Ecto = stratified squamous |
|
|
What are the epithelial cells of the Vagina?
|
Stratified squamous, NON-keratinized
(contains glycogen) |
|
|
What are the branches of the celiac trunk?
|
1) Common hepatic
2) Splenic 3) Left gastric |
|
|
What is the blood supply of the curvatures of the stomach?
|
Lesser curvature = Gastrics
- Prox = left gastric (straight from the celiac trunk) - Distal = right gastric (from hepatic proper) Greater curvature = Gastro-omentals + a "little gastric" - Prox (above splenic artery) = short gastrics (from splenic) - Prox (below splenic) = left gastro-omental - Distal = right gastro-omental (from common hepatic) |
|
|
What artery is usually the source of bleeding d/t gastric ulcers?
|
The Left Gastric a.
(proximal lesser curvature = most common spot for ulcers b/c it's b/w the body's HCl making parietal cells and the antrum's gastrin secreting cells) |
|
|
How does Staph aureus cause scaled baby syndrome?
|
Exfoliative exotoxin release
It is a protease that cleaves desmoglein in the desmosomes (b/w keratinocytes in the stratum granulosum = epidermis ONLY) |
|
|
What causes hepatic encephalopathy? What is the tx?
|
Ammonium detoxification d/t disruption of the NH4+ balance (↑protein = GI bleeding, ↓vol, ↓K+, ↓H+, ↓O2, ↓glycemia, infx, sedation)
Tx = Lactulose (gut bacteria ferment → acidic environment traps NH4+ for excretion) |
|
|
Which drugs decrease mortality in CHF? Which are only for symptomatic relief?
|
↓Mortality:
- ACE-I - ARB - ß-Blockers - Spironolactone (K+ sparing) Symptom relief: - Loop diuretics - Thiazide diuretics - Nitrates |
|
|
When does S3 occur, what is it a/w, and when is it normal?
|
S3 = early diastole, during the rapid ventricular filling stage.
a/w ↑filling pressures: - MR - CHF - dilated ventricles (most common) Normal in pregnancy and children |
|
|
How do you best appreciate the S3?
|
1) Use the Bell (high frequency)
2) Left lateral decubitus 3) Exhale (bring heart closer to chest wall) |
|
|
What would you order for a black patient with unexplained hematuria?
|
Sickle cell screen (could be causing medullary infarcts d/t low O2 in the medulla that ppt's sickling)
|
|
|
What drug will block the testosterone receptor and what is it good for?
|
1) Flutamide
2) Used in prostate carcinoma (will ↓ size of 1º tumor and mets) Administer w/ leuprolide (GnRH antagonist if tonic) to counteract the f/b ↑T when you block the T-R |
|
|
What causes Factor V Leiden? What is the resulting risk?
|
Missense SNP that:
- inserts GLUTAMINE - instead of ARGININE Near the Protein C cleavage site Increased risk of thrombosis (DVT → PE) - heterozygotes = 5-10x - homozygotes = 50-100x |
|
|
What is the classic presentation: middle aged woman with history of pruritis that recently develops fatigue and xanthelasma?
|
PBC = primary biliary cirrhosis
|
|
|
What are councilman bodies?
|
They are eosinophilic, apoptotic hepatocytes
Seen in hepatitis (viral or toxic) |
