1/9 You admit a patient overnight with hyponatremia and you diagnose it as SIADH. But how are you going to manage it?

To review how to diagnose SIADH, check out the volume-based or ADH/RAAS-based approaches below.

2/9 The cornerstone of treatment is to treat the underlying cause. Everything else is just a 🩹. It can sometimes be very hard to treat the underlying cause immediately (assuming you can identify it).
3/9 Free water restriction is going to help (to a certain degree), but make sure that it’s feasible for the patient (they often need to do this beyond hospitalization). Consider restricting 500 cc below their 24-hour urine output:
4/9 But what about in the first 24 hours of hospitalization? I arbitrarily do 1-1.5L restriction. Remember that the food the patient receives also has free water (that is quite difficult to quantify).
5/9 Let’s move onto 🧂. What dose should you order? It depends on the following questions:

1️⃣ How low is the Na?
2️⃣ Are they at risk for volume overload?

I start with NaCl 1g PO TID.
6/9 Next up we have urea powder. To read more about it: cjasn.asnjournals.org/content/13/11/…).

Start with 15g PO daily.
7/9 Next we have 0.9% NS (wait, I thought we started using LR for most things these days?). It’s a process called desalination:

For more reading: doi.org/10.1093/qjmed/…
8/9 Last, we have vaptans, which block the ADH receptor.
9/9 Here is a summary slide of all the options to manage SIADH – hope this helped! Feedback is always welcome.

1/16 Yet another fantastic AM report @LosAngelesVA!

Facilitator: @BrandonCSmithMD
Presenter: Danny Xu, MD (@uclaimchiefs PGY-2)

CC: lower back pain (LBP)

#MedTwitter #MedEd #FOAMed
2/ Brandon asked the group three questions:
1⃣ What is your approach to the pain?
2⃣ How does that inform your next steps for history and physical?
3⃣ How does that inform your next diagnostic steps?
3/ Group answers:
1⃣ We discussed an approach that is nicely captured by this slide
2⃣ The group wanted to know the tempo, progression and radiation
3⃣ Imaging at this juncture seemed premature but the thought was entertained

1/10 We often talk about evaluation of AKI in the context of ⬆️ creatinine, but let’s take a step back and think about eGFRs. Here is an approach to interpreting ⬇️ in eGFR! #NephTwitter #MedTwitter #FOAMed #MedEd
2/ This differential focuses on the estimated GFR (eGFR), which is calculated using serum creatinine +/- serum cystatin C levels (we will take a look at the equations in a bit). Biomarkers that actually measure GFR (such as inulin) are not clinically practical to obtain.
3/ Thanks to @ZacNephron for explaining GFR vs eGFR, referring me to Chapter 2 of @BookBurton, and sharing this thread to deepen my understanding of the utility of GFR:

1/10 As someone who struggles with test-taking, I made a framework for tackling some common test-taking hurdles. I had the opportunity to go over this with all our @uclaimchiefs housestaff and decided to make it into a 🧵 #MedTwitter #MedStudentTwitter #FOAMed
2/ Test scores are important because they are what you need to become board-certified. Scores are often conflated with competency - that is quite a fallacy as so many other factors go into competency.
3/ Here is a non-comprehensive set of examples of test-taking hurdles. Let’s go through each of them systematically in a way that resonates with internists - problem listing! FYI, all of these end of overlapping a lot

1/12 The cognitive load on rounds can be high, so I like using daily e-mails as an adjunct to teaching on rounds. Here is a 🧵 on my approach! #MedTwitter #MedEd #FOAMEd
2/ I am of the opinion that you can form an outline of a lesson plan BEFORE you even start on service! My group attends for 14 days at a time, so this tells me how much “time” I have allotted to teach (more on this later).
3/ Make sure to include every learner who will rotate with you while you are on (I use amion to figure out which trainees are on with me). They might appreciate getting learning when they are off service and if there is an ongoing thread of teaching, they won’t miss out!

1/8 Medical education has evolved tremendously, and I am a HUGE fan of having a peripheral brain. An common question trainees ask me is “how do you cultivate references?” A 🧵 on my methodology for organizing information #MedTwitter #MedEd
2/8 Before we start, it is important to categorize the purpose of the info you are gathering:
1⃣ To teach others
2⃣To teach myself
I don’t organize my references this way, but I start here to remind myself that everyone learns best with different modalities!
3/8 Now that we’ve acknowledged that, you must create a list of modalities that you can consistently categorize information into. Here is my organizational system.

1/18 Chest pain is a frequently seen reason for admission. Here's my take on when to consider ACS in patients with chest pain!
#MedTwitter #CardioTwitter #MedEd #FOAMed #MedTweetorial @MedTweetorials
2/18 Our evaluation of ACS starts with 3 things:

1⃣ History
2⃣ EKG
3⃣ Troponin

The primary focus of this thread is going to be on the history (a heads up - the flowchart at the end will go a little bit out of order)!
3/18 When taking a chest pain history, we ask lots of questions about associated symptoms and alleviating/aggravating factors, mostly because we were taught to obtain and report this history. But is there a more focused way to approach this? Image
