[Therapy of psoriasis].

The possible methods of treating psoriasis and results obtained are reviewed and the superior effectiveness of an approach reported in recent literature, an association of methoxalene per os and broad ultraviolet rays, is pointed out. In almost all cases submitted to such "photochemotherapeutic" treatment, regression of diffused lesions was rapid and complete with no systemic toxic effects or secondary skin alterations. On the basis of recent personal experience, it is stated that similar results may be obtained by the photochemotherapy of psoriasis with appropriate doses of Trisoralen per os and sunlight.

From an examination of all possible methods for the treatment of psoriasis and the therapeutic results obtained with them, the author emphasizes the outstanding efficacy of a method for the treatment of psoriasis only recent described in the medical literature, which consists of a combination of methoxsalen by mouth and longwave ultraviolet light. In almost all cases treated with this "photochemotherapy" a rapid and complete regression of the extensive psoriasis lesions could, in fact, be observed without being able to detect toxic systemic side effects or secondary alterations of the skin. As a result of a recent trial of his own, the author points out that the results of photochemotherapy of psoriasis can equally well be obtained with "Trisoralen" by mouth and sunlight.
