Abstract
Hospitalization medical treatment is the present standard although NB-UVB treatment is effective for psoriasis. Therefore, we decided to assess the NB-UVB treatment of 43 psoriasis outpatients. As a result, we found that it is necessary to treat two or three times during each week to achieve 75% score improvement. However, 50% score improvement did not show a significant difference between one and three times during a week. Therefore, although two or three times per week of NB-UVB treatment in psoriasis is optional, even one treatment per week appears to be enough to sufficiently raise a patient’s QOL.
