When you ask a patient with a terrific sense of humor for a stool sample #MedTwitter
medicine is basically just giving people fluid and getting fluid out of them, and then taking pictures with expensive machines to see if the fluid is there or not
Internal medicine is a medical discipline primarily concerned with evaluating, diagnosing, and treating whatever it was that upset the kidneys.
You cannot get educated by this self-propagating system in which people study to pass exams, and teach others to pass exams, but nobody knows anything. You learn something by doing it yourself, by asking questions, by thinking, and by experimenting. 🧠
Be honest with yourself... You’ve worn things that are a lot worse than wearing a mask.. #maskUp #WearAMask #mask
I carefully studied this every detail of this image from the most recent cover of @NewYorker this morning. Zoomed in and ran my finger over each face, each loss, each moment in time. Then I cried and cried. Damn. We been through a lot in this country, man. That’s all. #BLM✊🏽
I removed two Oxford commas from an abstract this morning in order to get it under the character limit, and now I feel like I've betrayed everything I stand for... #TeamOxfordComma
Some days I forget that coffee is not a resuscitation fluid 🤦🏻♂️
#BLM @BIDMC_IM @BID_CMRs @BIDMChealth Still work to do -- but a solid start. Proud of our institution for taking a knee to fight systemic racism.
Thank you #BIDMC_IM residents @AudreyLiMD Josh Dubow @dseth1106 and former @BIDMC_Medicine residents and current @bidhospitalists @JCoopermanMD @DanieleOlveczky for arranging this Kneel-in #WhiteCoatsForBlackLives we’re so proud of you!
1/ The conversation between my sons was so mundane. First they talked about Tiktok. Then about our upcoming vacation. It sounded so easy. I was glad. Son 1: “Hey mom? Is it okay if we rent bikes down there?” Me: *typing* “Sure.” Son 2: “Yes sirrrr!” *high fives brother*
After taking care of several COVID-19 patients on mechanical ventilation, I would like to say that my personal experience is of little use to others and you all should rely on evidence-based medicine. Thanks.
I keep thinking about all the times I grabbed a disposable glove from the box and like 3 gloves would come out and I would just throw away the other 2 gloves like some kind of disposable glove billionaire
Question for nephrologists that add “avoid unnecessary nephrotoxins” to their AKI notes, do you also tell consultant not to jam that pen in their eye and not to mix bleach and ammonia cleaner?
My shower drain has progressed from grade 1 to grade 2 diastolic dysfunction and let me tell you this has been clinically important.
When I said clear liquids before your cardiac catheterization were OK, I didn’t mean Vodka.
