@entity1 @entity483
In 1979-1981, 107 @entity1 with @entity483 were treated with Psorilux 9050 emitting 1.24 mW/cm2 at 280-315 nm and 7.33 mW/cm2 at 315-400 nm. Half of the @entity1 received one treatment course, 20% 2-3 courses, and one third more than 3 treatment courses. A good result was obtained in 93% of the cases but in the other cases the treatment was either ineffective or the @entity1 were too sensitive to the radiation. After the treatment, the need for treatment with topical corticosteroids had decreased in one half of the @entity1 and increased in only 2% of them. In 1982-1983, 89 atopics were treated with Metec Helarium model 1480, emitting both UVB and UVA (310-340 nm, with a peak at 320-330 nm). One treatment course, 3-45 weeks (mean 19 weeks), was given to 69 @entity1 , and two treatment courses to 20 @entity1 . The treatment was effective in 94% of the @entity1 . The others did not respond. After the treatment, the need of treatment with topical corticosteroids had decreased in 85% of the cases, and increased in none. Psorilux therapy caused II degree burns in two @entity1 and erythema lasting greater than 24 hours in 11 @entity1 . Erythema was encountered in 14 @entity1 receiving Metec Helarium therapy but in no cases II degree burns. Seventeen @entity1 received both Psorilux and Metec Helarium therapies and 14 of them preferred the latter.
