Necrobiotic xanthogranuloma.

A 67-year-old man presented with a 13-year history of slowly enlarging yellow-red plaques on the face and lower extremity. A biopsy specimen was consistent with necrobiotic xanthogranuloma. Necrobiotic xanthogranuloma is a slowly progressive histiocytic disease that is associated with paraproteinemia in most cases; however, its pathogenesis remains unclear. Although there is no first-line therapy, anecdotal reports have shown variable benefit with chemotherapeutic agents.

Etanercept does not effectively treat moderate to severe alopecia areata: an open-label study.

In this prospective, open-label pilot study, we evaluated the safety and efficacy of etanercept, a TNF-alpha inhibitor, in the treatment of moderate to severe alopecia areata, alopecia totalis, or alopecia universalis. Seventeen otherwise healthy adults with moderate to severe alopecia areata were enrolled. The primary outcome measure was the extent of hair regrowth during and after the end of treatment as evaluated by the Severity of Alopecia Tool (the SALT score). After between 8 and 24 weeks of continuous treatment with etanercept 50 mg given subcutaneously twice weekly, significant regrowth of hair was not shown in any of the subjects treated. Based on these results, etanercept appears to be ineffective in treating subjects with treatment-refractory, moderate to severe alopecia areata, alopecia totalis, or alopecia universalis.

Pharmacokinetics of topical calcineurin inhibitors in adult atopic dermatitis: a randomized, investigator-blind comparison.

OBJECTIVE: We sought to compare pharmacokinetics of pimecrolimus cream 1% and tacrolimus ointment 0.1% in adults with extensive, moderate to severe atopic dermatitis. Secondary end points included efficacy and safety. METHODS: Patients received twice-daily treatment for 13 days. Blood concentrations of pimecrolimus and tacrolimus were measured at days 1, 5, and 13. Treatment success was defined as an Investigators' Global Assessment score of 0 (clear) or 1 (almost clear). RESULTS: Tacrolimus was detectable in 36% of blood samples and pimecrolimus was detectable in 12%. In patients with measurable blood drug concentrations, systemic exposure to tacrolimus (mean area under the curve(0-10h) < 9.7 ng.h/mL; n = 7) was higher than to pimecrolimus (mean area under the curve(0-10h) < 2.5 ng.h/mL; n = 2). Whole-body treatment success (day 13) was achieved in 1 of 18 (5.6%) and 2 of 19 (10.5%) patients treated with pimecrolimus and tacrolimus, respectively, and face/neck treatment success in 5 of 18 (27.8%) and 5 of 19 (26.3%) patients, respectively. Patients included in the study were adult patients with severe atopic dermatitis. The results and conclusions drawn from this study population may not be applicable for the majority of patients with atopic dermatitis who have mild to moderate disease. CONCLUSION: Pimecrolimus appears to be associated with lower systemic drug exposure than tacrolimus.

Psoriasis: to cut or not to cut, what say you?

BACKGROUND: A common problem facing patients suffering from psoriasis is the need for surgery that requires incision through active psoriatic skin. Many patients have been denied surgery because of the fear of an increased risk of infection, decreased wound healing ability, and worsening of the psoriatic lesions. OBJECTIVE: To assess the practices and beliefs of dermatologists and surgeons (orthopedic and plastic surgeons) faced with the decision of whether to operate through active psoriatic skin. METHODS: Dermatologists, orthopedic surgeons, and plastic surgeons selected from various professional membership lists from five representative cities were sent a survey to ascertain their opinions on operating on active psoriatic skin. Psoriatic patients were also given forms asking about the severity of their psoriasis and whether they had ever been denied surgery. RESULTS: Dermatologists are more likely to condone surgery in active psoriatic skin and to believe that there is not a risk of increased infection or decreased wound healing than are orthopedic surgeons and plastic surgeons. These findings are statistically significant (P<0.05). CONCLUSION: With proper preoperative measures and dermatologic treatment, surgery can be performed on active psoriatic skin in most cases with minimal reservations, although a controlled, prospective study is necessary to arrive at a definitive conclusion.
