title: Application of controlled high dose rates in UV-B phototherapy for psoriasis.
abstract: The use of a cabin fitted with Sylvania UV-21 tubes, which have a very high output of UV-B radiation, made it possible to treat psoriasis patients with a maximal exposure time of 5 minutes per session. An exposure-control unit was used to measure and regulate the applied dose to prevent overdosage. The clinical results obtained with two comparable groups of psoriasis patients treated with Sylvania UV-6 or UV-21 tubes were equal.
