ABSTRACT
ObjectiveTo evaluate the clinical effect of ultra pulse CO2 laser in treatment of 32 patients with primary amyloidosis of the skin. Methods64 patients with primary amyloidosis of the skin were selected and randomly divided into two groups,the observation group(32 cases)and the control group(32 cases).The observation group were treated with ultra pulse CO2 laser,and the control group were treated by routine medicine method.Clinical effect were compared between the two groups after twelve weeks therapy. ResultsThe total effective rates of the observation group and the control group were 90.6%,53.2% respectively.There were a significant difference between the two groups(x2 = 11.13,P＜0.01).There were some different irritations in two groups after therapy,to give symptomatic treatment could help relieve.The relapse rate in the observation group was significant lower than that in control group after treatment of 3 ～ 6 months(x2 = 9.471,P＜0.01). ConclusionUltra pulse CO2 laser therapy of primary amyloidosis of the skin was safe and effective.
