In what clinical scenarios should we use the 2-day 2mg DST instead of the 1mg overnight DST for screening of Cushing syndrome?
The 2-day low-dose DST may be of some value in patients suspected to have nonneoplastic hypercortisolism (normal cortisol <1.4-1.8 ug/dL). The Dex/CRH test performs better in such patients, but the CRH is not available.
What is your approach to determining recurrent versus RAI-refractory differentiated thyroid cancer in patients presenting with metastatic disease several years after surgery?
It sounds like you already know that there is a non-iodine avid distant disease. A brain MRI is recommended to exclude CNS disease. If insurance allows, go to a PET/CT with a diagnostic CT of the neck and chest. If insurance will not allow PET, then diagnostic CT of the neck, chest, and abdomen with...
Is there enough evidence now to use injectable semaglutide as a foundational therapy for symptomatic heart failure with preserved ejection fraction in the setting of overweight or obesity?
While the evidence for using injectable semaglutide in the setting of heart failure with preserved ejection fraction (HFpEF) and overweight/obesity is promising, it's still considered emerging! STEP-HFpEF trial: This large, well-designed study showed that semaglutide significantly improved symptoms,...
What is your protocol to starting/stopping glucocorticoid replacement in Cushing disease patients after their transsphenoidal resection surgery?
The initiation of glucocorticoid treatment post-transsphenoidal surgery in patients with Cushing's disease varies across different medical practices. Dr. Fleseriu's paper provides a comprehensive review of Cushing's disease management, offering valuable insights (Fleseriu et al., PMID 34687601). Typ...
Do you routinely check a TSH level in patients with recurrent kidney stones who have hypercalciuria of unknown cause?
No. Although hyperthyroidism is a reported cause of hypercalcemia and hypercalciuria, it must be very rare cause of nephrolithiasis. I suspect the patient would be obviously hyperthyroid on examination. Hyperparathyroidism is a much more common cause of kidney stones. In my practice, if the stone an...
Following abaloparatide use for osteoporosis treatment, how long do you consolidate with bisphosphonates before considering a drug holiday?
6 months
How do you time Evenity after completion of Forteo?
If a physician is considering transitioning an osteoporotic patient from a PTH treatment to romosozumab, there is no reason to delay. It should be fine to start romosozumab immediately upon discontinuing PTH if it is clinically indicated. However, it is important to remember that romosozumab has a b...
In SIADH due to malignancy, do you prefer to use free water restriction or salt tablets?
Fluid restriction is usually the first line measure in chronic SIADH. Salt tablets only work at high doses, as SIADH is a water, not a salt problem, and you improve sodium only minimally. Tolvaptan is a very powerful drug, but, as per the package insert, must be started in an inpatient setting. Addi...
In a young female with severe osteoporosis due to congenital estrogen deficiency, can estrogen be prescribed if genetic testing for congenital disorders reveals a heterozygous Factor V Leiden mutation?
First of all, I don't think testing for inherited thrombophilia is warranted in a patient with no personal or family history of thrombosis. Given the multigenic nature of thrombophilia and our limited ability to test for it, it's difficult if not impossible to determine an individual's risk of throm...
How do you monitor risk of erythrocytosis from testosterone use for female to male transgender patients?
I utilize the Endocrine Society's guidelines for identifying secondary erythrocytosis secondary to gender affirming hormone therapy (GAHT) (PMID 28945902). For initial monitoring, at baseline and then every 3 month hematocrit for the first year and 1-2 times yearly thereafter is typically implemente...
