title: [UV irradiation devices for the treatment of psoriasis. Desirable spectra and various criteria for selection].
abstract: Special fluorescent lamps as well as filtered high pressure lamps are used for photo- and photochemotherapy of psoriasis. The spectra of the lamps offered for phototherapy are compared with the antipsoriatic range of action (lambda ca.295-315 nm) and judged by their therapeutic effect. The spectra offered for photochemotherapy should be free of UVB-radiation. Visible and infrared rays are not effective with psoriasis. The production of heat may stress the patient and require heat removal. On the skin surface the distribution of irradiation should be as even as possible. PUVA treatments of longer duration are preferably performed in a lying position. Closed irradiation units may produce claustrophobia . Open irradiation units require remote control. The most decisive economic factors are the duration of a single exposure as well as space requirements.
