CBSSA Flashcards
If I see an image of nucleated keratinocytes and a description of a red SCALY plaque in a sun exposed area, it is probably…
Actinic keratosis
Renal cell cancer is also known as
Renal Adenocarcinoma - highly vascularized – lower pole of kidney.
What is the most posterior portion of the heart that can cause compression of the esophagus and lead to dysphagia or hoarseness?
Left atrium
A widened aortic arch and diminished pulses in an extremity regardless of history including drug history is concerning for?
Dissecting aneurysm.
What is the physiologic correlate of STABLE angina?
It is ischemia to a vessel with greater than 60% occlusion.
What is the physiologic correlate to UNSTABLE ANGINA
Myocardial infarction - ACS?
Unstable angina: usually plaque disruption with clot formation and interrupted distal flow or vasoconstriction or mechanical occlusion or inflammation or increased myocardial oxygen demand
Myocardial infarction: Total occlusion of the coronary vessel
Full recovery in acute bacterial pneumonia can occur because
Alveolar exudate is lysed and absorbed. As long as there is no damage to vascular and endothelial tissue (including Basement membrane), there will be NO granulation tissue formed.
Type II pneumocytes are endodermal in origin.

What is the characteristic peipheral blood smear result in HELLP.
It is a MAHA due to high velocity damage against damaged endothelial cells. SCHISTOCYTES.
What determines the tropism of leprosy (mycobacterium leprae) to the dermis as opposed to the viscera?
Temperature (cooler temp preferred). Note that the lion facies version of leprosy (lepromatous is a TH2 response)
While the tuberculoid form of leprosy with hypoesthetic plaques is a Th1 response.
Both are treated with dapsone and rifampin. Add clofazimine for tuberculoid form.
What is the mechanism of action of Bisphosphonates?
Bisphosphonates are pyro phosphate analogs. Bind hydroxyapatite in bone INHIBITING OSTEOCLAST activity.
Erythema with no blisters after being in the sun
First degree burn.
What are struvite stones made of?
Ammonium magnesium phosphate. Struvite is the name of these stones and they are a nidus for UTI infection
What is the most posterior chamber of the heart that can result in dysphagia? Or hoarseness?
Left atrium
Where is the MLF located?
It is located in the brainstem by the third ventricle.
What is agraphesthesia?
In ability to recognize a number or letter written on skin.
What is unique about Vaccinia?
It is a poxvirus. These are DNA viruses but they ONLY REPLICATE IN THE CYTOPLASM because they carry all their replication machinery with them.
Influenza is unique in that it is a single-stranded RNA virus that replicates in the…
Nucleus! The only other virus that does this is Hep D virus.
Peek-a-boo is a proxy for
Object permanence (7-9months). Finger feeding happens around the same time (6-12 months).
Any time umbilication is mentioned with a skin rash, just pick
Molluscum.
Type II pneumocyte touches the wall and looks like it has substances within it.
