Would you start stone preventative medications such as potassium citrate and thiazide diuretics for patients with recurrent calcium based nephrolithiasis and abnormal 24 hour urine chemistries if they no longer have calculi on most recent imaging testing?
If they have had stones previously they remain at risk of recurrent stones. Would want to know when was the last stone episode. Was there previous treatment? It would be based on the results of the 24 hr urine and how significant is the hypercalciuria, oxaluria, low the citrate and pH are. Most impo...
Do you recommend life long aspirin 81 mg daily for non-specific T2 white matter hyper-intensities on MRI brain?
"Non-specific" means non-specific, indeed, and ASA risks of bleeding increase with age.
What is your preferred oral regime with duration for treatment of onychomycosis?
Back in the old days of the "toenail wars" between terbinafine and itraconazole, I was a speaker for both and learned that the pharmacodynamics of the two drugs favored pulsing for the latter but NOT for the former. Terbinafine does NOT leave the blood for weeks, unlike itraconazole (days), so if th...
What procedures do you recommend for patients interested in xanthelasma removal?
I have had success treating xanthelasma with both hyfrecation (particularly for very small lesions) and fully ablative laser (both CO2 and Erb-YAG).
What is your approach to diagnosis and evaluation of nonbacterial thrombotic endocarditis (Libman-Sacks)?
Nonbacterial thrombotic endocarditis (NBTE), also known as Libman-Sacks endocarditis, is a form of endocarditis characterized by the presence of sterile vegetations on cardiac valves. It is most commonly associated with systemic autoimmune conditions, notably systemic lupus erythematosus (SLE) and a...
For patients with microcytosis MCV 75-79 and normal Hb, low TIBC, and normal ferritin do you always rule out thalassemia?
Microcytosis is typical in thalassemia. With a normal ferritin and hemoglobin concentration, I would start screening by measuring HPLC, HbA2 levels that are high in beta-thalassemia carriers. (HbA2 can be normal with “mild” thalassemia alleles and for several other reasons.) Microcytosis without iro...
What is the target ferritin level for patients with hereditary hemochromatosis and signs of end-organ damage?
I believe the best marker to guide phlebotomy therapy for iron overload is the serum ferritin concentration. I use a target ferritin level of approximately 50 ng/ml. However, one could justify a ferritin level of <200 ng/ml from the literature of serum ferritin compared to body iron stores in HFE he...
Do you recommend the use of SGLT2 inhibitors to reduce the risk of liver cirrhosis in patients with Type 2 diabetes mellitus?
Metabolic dysfunction-associated steatotic liver disease (MASLD) can be found in about 30% of adults in the U.S. Diabetes is a significant co-morbidity and increases the risk of progression to metabolic dysfunction-associated steatohepatitis (MASH). I calculate a FIB-4 index in these patients to see...
How do you treat postpartum obsessive-compulsive disorder?
The ideal treatment for women who are breastfeeding is transcranial magnetic stimulation. TMS has a 50% response rate for OCD, higher if treatment is extended past the typical course of 30-36 treatments. This is similar to the response rates reported for SSRI treatment of OCD. Most women with post-p...
Would you consider using long-acting injectable cabotegravir/rilpivirine for pregnant women with HIV?
At this time, long-acting injectable cabotegravir/rilpivirine (CAB/RPV) is not generally recommended during pregnancy due to limited safety data and unknown effects on the developing fetus. So far, there have not been any reported safety concerns regarding harm to the fetus for either long-acting in...
