Myxedema Coma vs severe hypothyroidism
First #Medtwitter #Tweetorial #ICUconsult
Do I have the correct diagnosis ?
Why steroids ? Why cortisol ?
Do I wake up endo at 3AM ? #endotwitter
Looking for answers ? 👇
A thread 🧵
#Medthread #MedStudentTwitter #pccm
Myxedema coma is a medical emergency. Period.
Act fast, efficiently and start treatment if your pretest probability is very high. No TSH ? No prob.
We don't wait for a CTA in a patient with massive PE and don't wait for an arterial duplex in acute limb ischemia right? same here
Ok How do I know/suspect myxedema ?
1. #History (if severe pt may be obtunded, ask family!)
2. #physical #exam (thyroid scars, delayed reflexes, macroglossia, slow mentation, bradycardia, hypothermia, low BP, myxedema in extremities....)
when in doubt @uptodate
Before we go into diagnosis 2 things to ask/workup - Just like in #DKA always question #WHY the patient went into myxedema crisis ? #WHAT tipped them into it ?

Looking for #pathogensis ?
Say no more.
Looking for a scoring system to help diagnose myxedema? well we have one, limited utility but personally like it in cases where i'm borderline about the diagnosis #endotwitter #Endocrinology @SudiSarkar

What now ? Labs ! TSH T4 Cortisol BEFORE you start treatment. confirm prim/sec hypothyroidism + r/o adrenal insufficiency (2/2 associated hypopituitarism, blunted ACTH stress response due to disease)
no steroids = possible adrenal crisis
better to always be safe than sorry
✅steroids +thyroxine
✅looked/found potential triggers,
❓Add T3?
Rationale 1. faster action 2. more active 3. hypothesized that conversion from T4 to T3 is impaired in critical illness.
No general consensus - use what you have
And yes ok you can call endo now
Paging @medpedshosp @gradydoctor @thecurbsiders @ShreyaTrivediMD @DoctorVig @DocWithBowtie
may I pls have some hospitalist feedback ? Have you guys seen myxedema on the floor and managed without ICU level of care?
@DocWithBowtie @medpedshosp @gradydoctor @thecurbsiders @ShreyaTrivediMD @DoctorVig Also reg the blurry gray area - this scoring system helps - I asked my endo folks about this gray area - if score <60 no Brady no hypothermia no major o tunes toon cannot call it myxedema
@DocWithBowtie @medpedshosp @gradydoctor @thecurbsiders @ShreyaTrivediMD @DoctorVig Lol I don’t understand how “major neuro deficits” can autocorrect to “tunes toon” 😂
@t_swam FYI more on t3 from other experts on the thread - Youll have to dig :P
