Ah, yes, the "you gotta know this cold" lecture --- at TCOM they had us convinced that pheochromocytomas were out there, in mass numbers, carefully hidden, waiting to leap upon unsuspecting medical students/interns/residents and foolish physicians who didn't pay appropriate tribute --- what utter BS --- if it's coming from a Ph.D, they're not clinicians and most don't know F-all about what we do -- they're great at basic sciences and moving the body of knowledge forward but when it comes to diagnosing and treatment, not so much....
if it's coming from a specialist -- sure, in their world, you gotta know it cold --- because they're usually experts in maybe 2-3 things and have shaped their practice as such -- at the medical student level, you need to be developing a general database of pathology -- something that will trigger in your mind,"I've seen this somewhere before and it's usually vascular -- let me go look it up" --- rather than being able to immediately recall from memory the histology, pathology, presenting symptoms, lab workup and treatment options of each and every vasculitis -- remember that's why they call it residency and clinical practice -- you're building a knowledge base layer by layer that will gradually look like a pyramid with the stuff you use every day at the top and the rest will be out there somewhere, enough to tickle something in the brain-housing group ---
Heck, you'll never really shake the feeling of "I need to learn more, I just don't feel like I know this well enough" -- if you do, watch it, because you're about to get dangerous --- my attending surgeon during MS3 was a Harvard undergrad/med school/Mass General trained general surgeon with over 20 years of surgical practice -- I noticed one afternoon during some downtime that he was reviewing for the cases he had scheduled for the next day -- I asked him when he had stopped reviewing the surgeries prior to doing them --- he told me that he still went over the steps of each one and the potential complications and anatomic variants to be ready for prior to each one -- even if it was briefly ---
