title: 311 nm UVB lamps in the treatment of psoriasis with the Ingram regimen.
abstract: A new experimental fluorescent lamp emitting UVB mainly in a narrow peak around 311 nm was compared with a conventional broad band UVB lamp in the treatment of psoriasis with the Ingram regimen. In 20 patients one arm was treated with the new lamps and the other arm with conventional lamps. In 12 patients the results were same, but the new lamp was more effective in 8 patients. In another trial, 53% of 17 patients treated with the new lamp showed good results compared with 30% of 23 patients treated with conventional lamps. In conclusion, the 311 nm UVB lamp is at least as effective as the conventional broad band UVB lamps in the treatment of psoriasis with the Ingram regimen.
