What is your diagnostic and treatment approach for patients hospitalized with erythroderma?
I would like to know details regarding the patient's medical and family history since underlying primary dermatologic disorders, onclogic disorders, genetic disorders, medications, and infections can trigger erythroderma with medical complications.
Do you change your approach to prednisone taper based on rituximab dosing regimen when treating patients with pemphigus?
My approach to prednisone course/tapering at treatment outset or subsequent rituximab is typically dictated by clinical parameters, specifically PDAI/severity and potential comorbidities, rather than rituximab dosing regimen. This paper supports the notion that similar cumulative steroid exposure an...
Are there patients with pemphigus whom you plan to give additional doses of rituximab even if they are in complete remission at six months from their initial dose?
It depends on what you consider "complete remission". Antibody levels and types, both before and after treatment, probably help predict relapse. Generally, we plan to give another rituximab dose at 6 months and reassess a few months ahead to see if any predictors of relapse are present, with a fairl...
What topicals have you had success with treating body acne?
Agree with Jim Leyden that systemic therapy, especially isotretinoin, is far superior to topical therapy in treating truncal acne. However, in patients who refuse systemics, some of the newer topicals may be helpful. The newer retinoid formulations, trifarotene cream and tazarotene lotion, both have...
What treatment modalities have you had success with for treating sebaceous hyperplasia?
I have used light electrodesication with a blunt tip needle with good effective results without visible scarring for the vast majority of patients. I find that it is efficient and less expensive than laser modalities. The procedure is uncomfortable for my patients and typically I need to use topical...
Is it safe to use one TNF inhibitor (e.g., infliximab) in a patient who has had a severe allergic reaction to a different TNF inhibitor (e.g., adalimumab)?
The short answer is yes - it is ok to proceed with a different TNFi. First, it is important to determine whether the reaction was truly allergic or a nonspecific infusion reaction instead. If possible, obtaining a serum tryptase level at the time of the reaction can help clarify. Realistically, this...
How do you counsel patients who express concern about potentially harmful ingredients in sunscreens?
First, I acknowledge that there can be confusing and sometimes alarming information in the media about sunscreens. I like to point out that unprotected sun exposure is the primary driver of skin carcinogenesis and that it is more harmful than any known risks of sunscreen to date. I discuss that ther...
In patients with livedoid vasculitis and chronic venous insufficiency on rivaroxaban, what therapeutic strategies—beyond compression and topical care—are safe and effective for controlling pain, ulceration, and edema?
My experience has been that aspirin 365 mg, plus persantine or trental daily, plus leg elevation for 45 min or so in mid-afternoon, will produce pain relief and onset of healing within about two weeks. Only infrequently have I had to resort to metformin as an added medication or use both trental and...
Do you avoid progestin only contraceptives and IUDs in patients with acne due to their androgenic properties?
I counsel similarly to Dr. @Dr. First Last above. I also reference the following article, which shows the following odds ratios for certain conditions with hormonal IUDs vs copper: Acne vulgaris: 2.514 Hirsutism: 0.446 Rosacea: 0.376 Androgenetic alopecia: 0.109 Basically, I say they're less likely ...
Is there a role for resection of the cutaneous primary in a patient on dual-agent immunotherapy for metastatic melanoma?
Yes. The location and size (width, length) should be noted. The patient should first be treated with dual ICI. If the patient with metastatic melanoma, who has the primary intact, undergoes successful dual ICI therapy and has a documented CR, near CR, or excellent PR, which is typically noted within...
