USMLE Tip: Here's a pedigree from a Free 120 question that you should recognize immediately on sight. Key findings: Only males affected. No male to male transmission. This is X linked recessive. II-1 must be a carrier (female with affected male parent). Chance of ? being an…

USMLE Tip: Any drug that reduces afterload (ACEi, ARB, Dihydropyridine CCBs) can increase ejection fraction. Less afterload = increased stroke volume = increased LVEF (SV/EDV). Caveat: In actual practice, it's rare to see LVEF increase by echocardiogram when patients start these…
USMLE questions evolve over time. Let's say there's a question that basically asks, "What's a risk factor for renal cell carcinoma? Answer: smoking." At first, suppose 75% get it right. That works so it circulates a while. But later 90% get it right because students talk,…

Good stuff
I doubt this finding comes up on Step exams much but they love to show it during ED teaching conferences and ED rotation exams. Easy to recognize if you’ve just seen it. Osborn wave from hypothermia.

When doing UWorld, AMBOSS or NBMEs, how much time do you spend per question reviewing the answer explanations (on average)?
I wonder what AI will do to the future of video-based learning. It's great to watch a video that explains concepts well, but if you get confused or want to know more, you can't ask the video questions. With AI, you can go back and forth like a teacher and student one-on-one. For…
USMLE Hematology Tip: Patient starts warfarin and develops the skin lesion below. What's the cause? Protein C deficiency. The lesion is skin thrombosis from hypercoagulability. Warfarin →protein C falls → thrombosis. The protein C decline is usually not enough to cause…

Is anyone just putting page after page of First Aid into ChatGPT and asking the AI to explain the concepts and then make up practice questions? Seems like this might work for people without money to buy 3rd party resources.
These are the kinds of cases that make me so sad about the state of medicine. Invasive procedures on 88 year olds with dementia should be extremely rare. Evidence of benefit to the patient should be overwhelming. Very few things meet this standard. Definitely not LAAO.
