Abstract
The therapeutic efficacy of conventional superficial radiotherapy and topical psoralen photochemotherapy (topical PUVA) administered over a 6 week period was compared in a double-blind study of 21 patients with chronic bilateral constitutional hand eczema. One hand was treated with conventional superficial radiotherapy and the other with topical 8-methoxy-psoralen and long-wave ultraviolet light (topical PUVA). Significantly better clinical improvement was seen in superficial radiotherapy treated hands over topical PUVA treated hands after 6 weeks of treatment, but this difference was not maintained at 9 or 18 weeks. There was no significant difference in symptom severity between the two treatments after 6 weeks, but superficial radiotherapy produced significantly more symptomatic improvement at 9 and 18 weeks. Superficial radiotherapy is a less time consuming procedure than topical PUVA and leads to more rapid improvement.
