Abstract:
Some of chronic benign recurrent dermatoses are markedly recalcitrant to the ordinary dermatological treatments. The author studied the therapeutic effect of beta ray on those of 30 patients including 6 cases of psoriasis, 3 of lichen simplex chronicus, 9 of nummular eczema, 8 of pustulosis palmaris et plantaris, and 4 of chronic eczema of the finger. All of the above were promptly recurred with ordinary treatments. Strontium 90 applicator was used as the source of beta ray and the total irradiation doses to each sites were ranged from 600 to 1500 rads in divided doses(usually weekly) over 2 to 3 weeks. The results were as follows, 1. In psoriasis patients with papular type were cleared by strontium 90, however, with chronic localized plaque type were poorly responded. The relapses of the cleared papular type were noticed between 13 to 24 days intervals, and it appeared that the larger doses did not influence significantly the clinical results. 2. Almost all of the chronic eczematous dermatoses including lichen simplex chronicus, nummular eczema, pustulosis Palmaris et plantaris, and chronic eczema of the finger, which were irradiated by beta rays following clearance with preliminary corticosteroid therapy, were recurred between 2 to 4 weeks intervals. However, larger doses resulted in prolonged recurrence intervals in a few patients. 3. No noticeable eariy hazards of irradiation were detected except for the mild hyperpigmentation on the irradiated skin.
