#Rheumatology Fun

Let’s take a deep dive into a unique subset of rheumatic diseases 👇

This week's RTL guest tweetorial from @MithuRheum! CASE 1:

🔹A 52 yo male presents to clinic w/ 6 months of hand ulcerations on the dorsal surface of the hands & elbow, oral ulcers, a violaceous periorbital rash and mild arthralgias

🔸CT chest demonstrates nodular opacities

⁉️Did you know the left atrial appendage can be described as chicken wing🍗, cactus 🌵, windsock, & cauliflower morphology⁉️

Full 🧵on 💘Atrial Fibrillation💘

🥇First, let's review the basics of atrial fibrillation (A.fib)

✨Most common cardiac arrhythmia✨

Etiology:
-🎆Rapid firing from foci in pulmonary vein triggers reentrant waves🎆

EKG:
-RR intervals have no pattern ➡️ irregularly irregular
-No distinct P waves

Based off of Run the List Episode 24, here is a #tweetorial on💘Tachyarrhythmias💘

🎧Full episode: bit.ly/3b6svs0

Let's start with an EKG 👇 (@medicine_strong). For more practice, check out: bit.ly/35mxD7P

Thanks to @Gurleen_Kaur96 for this week's edition! ❓What tachyarrhythmia is shown on that EKG above❓

Keep these things in mind when interpreting:
🔶Rate
🔶Regularity
🔶Width of QRS complex
🔶Relationship of P wave to QRS complex

And continue reading this 🧵 for the correct answer...

Based on Run The List 📝 Episode 48, here goes nothing with a #tweetorial on lymphadenopathy (LAD)

Thanks to Kushal (@k_vaishnani) for this week's RTL edition! What’s 🔑 in narrowing down the etiology of lymphadenopathy?

🔸LOCATION of LAD (axillary, supraclavicular, inguinal)

🔸Detailed HISTORY (including exposures, travel, constitutional symptoms)

Below is a helpful list of exposures & associated LAD 👇

Let's HIT the topic 💊 Heparin-induced Thrombocytopenia (HIT)🩸!

This #tweetorial is a deep dive into Episode 43 of Run the List (RTL) on Thrombocytopenia: bit.ly/32feVfQ

Thanks @LeelaChock for covering this week’s topic! Thrombocytopenia is a broad topic!

In Ep. 43 of RTL, Dr. Robert Stern, @NavinKumarMD, & @sonorato11 go over a general approach to thrombocytopenia 👇

Broadly, there are THREE umbrellas:

1. ⬆️ destruction

2. Splenic sequestration 💪

3. ⬇️ production

Factor V Leiden 🦁 & Protein C/S deficiency 🐯 & VTE 🐻, oh my!

In this #tweetorial, we're going to tackle Thrombophilia & Anticoagulation

Thanks @_blake_smith for this week's edition ICYMI

🎶catch Episode 47: Thrombophilia & Anticoagulation here: apple.co/2XhpRIU

In it, hematology expert Dr. Jean Connors @connors_md begins with a review of hemostasis🩸(coagulation)

Who's ready for another #tweetorial?!

This week on HYPOCALCEMIA 🥺🥛

ICYMI, listen to our "Episode 35: Hypocalcemia" pod: apple.co/2XhpRIU In the episode, Dr. OP Hamnvik @ohamnvik drops an early pearl & teaches us that the clinical manifestations of hypocalcemia occur depending on:

1) TEMPO

2) DEGREE of hypocalcemia

How quickly did the Ca drop & by how much?

If there's been a gradual⬇️ -> pt can be asymptomatic

Handout from our Endocrinology episode, "Episode 33: Hypercalcemia" with Dr. OP Hamnvik @ohamnvik is now out!

check out👇for a #tweetorial on PTH-dependent & PTH-independent causes of hyperCa First things first, calcium is *tightly* regulated in the bloodstream (nl = 8.6 - 10.2 mg/dL)

TOTAL calcium exists mainly in two forms:

1⃣Ionized = FREE fraction
+
2⃣Bound to protein (albumin)

*note that the FREE/ionized fraction is what controls parathyroid hormone (PTH)

Yesterday, we released an important episode "Introduction to Health Inequities" w/ Dr. Utibe Essien @UREssien

Today, we share the episode's handout made by Dr. Moses Murdock @haematognomist including referenced landmark texts in health disparities & other anti-racism readings👇 As Dr. Essien @UREssien discusses in the episode, the COVID-19 pandemic "opened our eyes and laid bare structural inequities that exist in our society"

Ex-Obama CMS lead @ASlavitt began describing these racial disparities here:
