When do you check vitamin D levels in patients with depressive symptoms?
I routinely check 25-OH D in all my patients. Given that half the population is deficient and that we now know the role of vitamin D not only for bones but in mood, cognition, and immunity. We need to be aware of deficiencies and replete if low. Moreover, ideal levels are 60-80, not just over 29 as ...
Do you get DEXA scans routinely before starting ADT for prostate cancer or endocrine therapy for breast cancer?
When initiating long-term ADT, I order a DEXA scan, check vitamin D level, ensure adequate dietary calcium intake, and discuss weight-bearing exercise/refer to PT when appropriate. I also continue check DEXAs every 2 years unless they otherwise meet criteria for a bone-modifying agent (mCRPC with bo...
Would you recommend RAI ablation therapy to patients with PTC who are s/p hemi-thyroidectomy and decline completion thyroidectomy despite meeting criteria based on pathology results?
RAI therapy will work to ablate the remaining thyroid lobe with about a 69% success rate using high dose of I 131. However, extra-thyroidal tumor cells will likely not pick up I 131 with this treatment. A good reference is the 2020 meta-analysis in the journal of nuclear medicine: Piccardo et al., P...
In adults ≥80 years with TSH 6–10 mIU/L and minimal symptoms, do you initiate levothyroxine, monitor, or avoid treatment entirely?
I tend to check free T4 in this situation. Aging is associated with some elevation in TSH value up to 10 mIU/L with normal free T4, and in those patients, levothyroxine is not needed. In some patients, I have seen it rise above 10 with normal free T4. Supplementing levothyroxine to lower serum TSH w...
What is the evidence, if any, for the use of low dose naltrexone in the treatment of autoimmune thyroiditis?
I do not prescribe naltrexone for thyroid disease because I have not found data to support its use. In theory, low dose naltrexone (LDN) could decrease inflammation and thus potentially block development of overt hypothyroidism in TPO positive patients. But, at this time, it is anecdotal, with no ha...
If a patient requires more than 5 mg per day of methimazole long term do you recommend alternative treatment options such as radio-iodine ablation or surgery?
Long term use of methimazole is generally safe as long as no history of LFT elevation or abnormally low white blood cell counts. Typically, toxic multinodular goiters respond well to low dose methimazole and patients can be managed in this fashion long-term without any issues. Graves patients may re...
How does a strong family history of breast cancer influence your decision between RAI and thyroidectomy for definitive treatment of hyperthyroidism, in light of emerging observational data suggesting a possible association between RAI and increased breast cancer risk?
There is an increased risk for solid tumors, especially breast cancer, following radioactive iodine (relative risk from 0.45-2.55). This data is strongest for those treated for thyroid cancer as opposed to Graves disease, as it is dose dependent, but studies do support an increased risk for breast c...
Would you favor the use of denosumab over bisphosphonate therapy for treatment of osteoporosis in patients who are at high risk for osteoarthritis given recent data suggesting reduced risk of developing knee OA?
Although the overall data to date concerning the impact of denosumab to reduce incident knee OA or lessen established disease remain limited, there are sufficient signals that warrant further investigation and support the need for an appropriately powered RCT with endpoints that include both patient...
What triggers you to choose urgent thyroidectomy versus therapeutic plasma exchange versus continued medical management for refractory thyroid storm despite 12-24 hours of guideline-concordant therapy?
A very important factor is the comfort level of the ICU doctors and the Anesthesiologists at the institution. We usually do not recommend proceeding with urgent thyroidectomy given the increased risks, unless FT4 and TT3 are normalizing. Usually, a combination of PTU (or Methimazole), stress dose st...
Is there any role for bisphosphonate or alternative bone-modifying agents use in SMM in the absence of other indications for its use?
The short answer is no, unless the patient has an indication like osteoporosis. Bisphosphonates have been evaluated in smoldering multiple myeloma in studies performed over 10 years ago. Treatment with pamidronate (D’Arena et al., 2011) or zoledronic acid (Musto et al., 2008) did not affect the time...
