ABSTRACT
Objective:To evaluate the efficacy and safety of water injection therapy combined with medical moisturizing repair cream in the treatment of rosacea.Methods:Total of 100 patients with types I and II rosacea in the Department of Dermatology, the First Affiliated Hospital of Army Medical University were randomly divided into three groups: comprehensive group (treatment group), hydrate group (control group 1) and moisturizing group (control group 2). Comprehensive group and water light group were given water injection therapy, once a month, a total of 3 times of treatment; in the comprehensive group and the moisturizing group, topical medical moisturizing repair cream was used once in the morning and in the evening, for a total of 12 weeks. After unified training, the therapists evaluated the skin lesions according to the scoring criteria and recorded the adverse reactions, for a total of 12 weeks.Results:After 12 weeks of treatment, the integral difference values before and after treatment were 8.01± 2.43, 7.68±2.16 and 5.63 ±2.19 respectively in the comprehensive group, the water injection therapy group and the moisturizing group, with statistically significant differences ( P<0.05). The effective rates of the three groups were 94.38%, 89.91% and 48.12%. No serious adverse reactions were observed. Conclusions:The water injection therapy combined with medical moisturizing and repairing cream is safe and effective in the treatment of rosacea; it is more effective than the moisturizing and repairing cream.The water injection therapy combined with medical moisturizing and repairing cream has advantages but is not obvious enough.
ABSTRACT
Objective To evaluate the efficacy of combined therapies of ablative fractional Er ∶YAG laser (2,940 nm) and ALA-PDT on refractory verruca plana.Methods 120 cases of refractory verruca plana patients were randomly divided into two groups:60 cases in the control group and 60 cases in the experimental group.The control group used 10％ ALA-PDT with LED irradiation of a power density 70 of mW/cm2 at a distance of 20 cm,which lasted for 20 min each time.The experimental group was treated with ablative fractional Er ∶ YAG laser (2,940 nm) first with the fluence of 500P/cm2 and short pulse duration,and then treated 10％ ALA-PDT as mentioned before.Every patient was treated twice at two-week intervals.Three independent investigators evaluated subject outcomes at 3 months post-treatment including efficacy and side-effects.Results The effective rate of the experimental group was 86.44 ％ at 3 months post-treatment after one to two times.Meanwhile,the control group was 59.65 ％.The clinical outcome of experimental group was better than the control group.There was significant difference between the two groups (P＜0.05).The recurrent rate of experimental group was 3.39％ and 12.30％ in control group.There was significant difference between the two groups (P＜0.05).There were no obvious side-effects in both groups.Conclusions Ablative fractional laser with low fluence promotes the transdermal absorption of ALA and enhances the efficacy of PDT.
