How do you manage arthritis resulting from deferiprone in transfusion dependent thalassemia?
The precise pathophysiology of deferiprone associated arthropathy is not well understood but some reports have suggested that there may be some deposition of iron in the synovial membranes, and some subchondral bone damage. Unfortunately, there is no specific treatment for this arthritis, other than...
In patients undergoing MRI evaluation for inflammatory back pain, how long do you recommend they hold NSAIDs prior to imaging?
The other issue regarding NSAIDs and MRI is whether these agents will suppress the bone marrow edema signal which has been demonstrated in some patients. Therefore, it is recommended to hold NSAIDs for at least 3 days prior to the MRI.
Would you recommend a neck soft collar after a cervical internal carotid artery dissection?
I would sincerely doubt that would have any benefit. Avoiding more strenuous or sudden trauma would be more appropriate.
Would you recommend a CT venogram or MR venogram in patients with concern for venous sinus thrombosis?

Do you recommend any particular type of contraceptive use in young patients with strokes of unclear etiology?
The safest choice would be a progesterone-only method. If a combination must be used, the lowest estrogen option.

If excessive supplements are consumed, B12 is innocuously excreted in the urine once tissue receptors are saturated. Nonetheless, this question raises some interest...
Is there a correlation between spleen size and degree of thrombocytopenia?
In a normal individual, approximately 1/3 of total body platelets are sequestered in the spleen at any given time. As the size of the spleen increases, so too does the proportion of platelets in the spleen increase. This is due to the total volume of the spleen, not just longitudinal measurement. It...
When do you start bisphosphonates empirically, irrespective of DEXA results, in patients going on chronic glucocorticoids?
I think this is an important question. I personally got really interested in bone in large part because of all the glucocorticoids that I was using to treat serious inflammatory diseases. I was fortunate to spend time with Dr. Howard Polley from Mayo when I was a fellow. He was on the team that gave...
Can romosozumab be used in patients on dialysis?
This is an interesting question given the common finding of osteoporosis among patients undergoing hemodialysis. There have been several individual case reports suggesting that treatment with romosozumab in this patient population can be safe and effective. The largest study (no control group) of wh...
