In an attempt to stop the evolution of recent-onset severe alopecia areata (AA), we tested pulse corticotherapy on 9 patients. Acceptance into the study was based on the following criteria: recent-onset AA (< l year), AA in an active state, bald surface > 30% of the scalp, no contraindication to pulse corticotherapy. Each patient was given 250 mg i.v. of methylprednisolone twice a day on 3 successive days. In 8 patients the course of the ongoing episode of AA was stopped. At the 6-month follow-up, a regrowth on 80–100% of the bald surface was observed in 6 patients. One patient did not respond to treatment, and 2 had less than 50% of regrowth. This open study suggests that pulse corticotherapy: (1) can stop the course of severe AA in an active state, (2) is well tolerated without major side effects and (3) does not permit a stable control of AA of more than 1 year duration. This treatment seems to be indicated for severe AA of recent onset.
Emulsifiers are common constituents of most topical preparations. To study the sensitization rate in a population with frequent use of these agents, we selected 47 patients with chronic or recurrent (> 1 year) inflammatory skin disease (leg ulcers, contact dermatitis, atopic dermatitis, psoriasis) for patch testing with the following emulsifiers: Tween 40 (polyoxyethylene sorbitan monopalmitate). Tween 80 (polyoxyethylene sorbitan monooleate), Span 60 (sorbitan monostearate), Span 80 (sorbitan monooelate), Arlacel 83 (sorbitan sesquioleate), Atlas G 2162 (polyoxyethylene oxypropylene stearate), Atlas G 1441 (polyoxyethylene sorbitol lanolin derivative), triethanolamine, Lanette O (cetylstearyl alcohol), Lanette N. 12 patients had at least 1 positive reaction (25.5%) at 3 or 4 days. Among them, 10 had leg ulcers (43.4% of the leg ulcer group), and 2 had contact dermatitis (13.3% of the contact dermatitis group). No positive reaction was observed in the other patients. When the patients were tested with their own topical preparations or wound dressings, 6 of them, all with leg ulcers, had positive reactions. These results show a surprisingly high prevalence of sensitization to emulsifiers in patients with chronic leg ulcers, in contrast to patients with other inflammatory skin diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
