What has been your experience with tecovirimat for monkeypox?
I thought it worked well in 2 patients of mine with rectal Mpox. However, the clinical trial did not confirm this, and it was a lot of trouble to get TPOXX going with consent, investigational drug, etc so we have abandoned use here.
When do you recommend HLA testing prior to prescribing lamotrigine, carbamazepine, or oxcarbazepine to patients of Asian descent?
I never use carbamazepine, given how it’s a pan-inducer and often lowers the level of other medications that may be in the regimen, such as quetiapine and haloperidol, since they are mainly metabolized by CYP3A4.Oxcarbazepine has a 50% reduction in the induction of carbamazepine, so I use that somet...
Is there a preferred JAK inhibitor for the treatment of alopecia associated with childhood-onset systemic lupus erythematosus?
Unfortunately, this question likely comes down to FDA and insurance approval and not scientific evidence. Since only one JAKi is approved for alopecia right now and and 2 for poly JIA and none for SLE currently in any age, it will come down to which diagnosis you are going to use to get coverage.
Have you used itraconazole as a primary or adjunct therapy for individuals with numerous BCCs?
Yes. I use itraconazole 100 mg daily with sonidegib 200 mg (daily or less frequently, depending on tolerance, but no less than twice a week) in every patient who shows a resistant SMO mutation on an NGS panel. I test all patients at baseline and at recurrence to determine what treatment to offer.
For patients on medications that are known to cause photosensitivity, would you counsel them to avoid laser hair removal or laser therapies?
"Known to cause photosensitivity" is almost every drug, but actually isn't all that common. I Rx doxycycline all summer and maybe see a possible reaction every few years. Variables are the dose of the drug and the amount and wavelength of light, but mostly studies are lacking. A test spot might giv...
What is your escalation strategy for chronic GvHD?
There are now several available options for steroid resistant cGVHD. The old standbys - ECP and rituxan are useful in about 30% of patients. Ibrutinib was the first new drug to get FDA approval. Unfortunately, I don't think the real-world experience is anywhere near as good as the trial (Chin et al....
How do you reconcile the differing results of the C-POST and KEYNOTE-630 trials when discussing treatment options with high-risk CSCC patients?
I explain that the two trials enrolled different risk populations, which likely accounts for the apparent discrepancy in outcomes — but when you look closely, they actually lead to the same clinical conclusion. C-POST deliberately enriched for very-high-risk patients (using well-established adverse ...
Do you prefer Cantharidin Plus or Y-canth for management of pediatric molluscum?
I don't like cantharadin plus over Y-canth because I don't like the plus. I still prefer plain cantharadin by a large margin over both.
Have you used topical rapamycin/sirolimus for TSC-related angiofibromas?
I used it before it was approved for the treatment of vascular lesions and noted that it was effective and safe.
What is the value of resection in high risk (but small or early stage) skin cancers at the medial canthus?
The value of resection of a high risk small or early stage skin cancer at the medial canthus is potential assurance of complete removal of the skin cancer by confirmation of negative margins. Depending on the extent of disease and surgical approach, this may or may not be straightforward. There are ...
