Pearls from 10/27/20 Medicine LEADS

Thursday, October 29, 2020

The Oct. 27, 2020 session of Duke Medicine LEADS featured Diana McNeill, MD, MACP, presenting "Clinical Dilemmas in Endocrinology."

Here are pearls and takeaways from the session:

  1. Biotin interferes with your free T4 assay. If you see a patient with elevations in TSH and FT4 ask about Biotin supplements.  
  2. As part of your hypercalcemia work up, consider checking a PTHrp in the appropriate patient when you are concerned about cancer and hypercalcemia. 
  3. Megace and intermittent use of oral steroids can cause adrenal insufficiency and lead to an adrenal crisis in patients.  
  4. HbA1C only diagnoses 30% of cases of diabetes. Post prandial elevated blood sugars, reactive hypoglycemia, or gestational diabetes can be harbingers of diabetes. Consider checking for diabetes with a different confirmatory test like a fasting blood glucose or glucose tolerance test if you suspect diabetes and your patient has a normal HbA1C.
