Promising Option for Treatment of Striae Alba: Fractionated Microneedle Radiofrequency in Combination with Fractional Carbon Dioxide Laser

Background. A consistent treatment has not been proposed for treatment of Striae Alba (SA). The present study was designed to compare the fractionated microneedle radiofrequency (FMR) alone and in combination with fractional carbon dioxide laser (FMR + CO2) in the treatment of SA. Methods. Forty-eight pairs of SA from six patients were selected. Right or left SAs were randomly assigned to one of the treatment groups. The surface area of the SA before and after treatment and clinical improvement using a four-point scale were measured at the baseline, after one and three months. Results. The mean age of the patients was 30.17±5.19 years. The mean difference of the surface area between pre- and posttreatment in the FMR + CO2 group was significantly higher than that in the FMR group (p=0.003). Clinical improvement scales showed significantly higher improvement in the FMR + CO2 group than in the FMR group in the first and second follow-up (p=0.002 and 0.004, resp.). There were no major persistence side-effects in both groups. Conclusions. The results showed that FMR + CO2 laser was more effective than FMR alone in the treatment of SA

Clinical Study Topical Colchicine Gel versus Diclofenac Sodium Gel for the Treatment of Actinic Keratoses: A Randomized, Double-Blind Study

Introduction. Actinic keratoses (AKs), a premalignant skin lesion, are a common lesion in fair skin. Although destructive treatment remains the gold standard for AKs, medical therapies may be preferable due to the comfort and reliability .This study aims to compare the effects of topical 1% colchicine gel and 3% diclofenac sodium gel in AKs. Materials and Methods. In this randomized double-blind study, 70 lesions were selected. Patients were randomized before receiving either 1% colchicine gel or 3% diclofenac sodium cream twice a day for 6 weeks. Patients were evaluated in terms of their lesion size, treatment complications, and recurrence at 7, 30, 60, and 120 days after treatment. Results. The mean of changes in the size was significant in both groups both before and after treatment (<0.001). The mean lesion size before treatment and at 30, 60, and 120 days was not different between the two groups ( > 0.05). No case of erythema was seen in the colchicine group, while erythema was seen in 22.9% (eight cases) of patients in the diclofenac sodium group ( = 0.005). Conclusions. 1% colchicine gel was a safe and effective medication with fewer side effects and lack of recurrence of the lesion

Comparison effect of azithromycin gel 2% with clindamycin gel 1% in patients with acne

Background: Acne vulgaris is the most common skin disease. Local and systemic antimicrobial drugs are used for its treatment. But increasing resistance of Propionibacterium acnes to antibiotics has been reported. Materials and Methods: In a double-blind clinical trial, 40 patients with mild to moderate acne vulgaris were recruited. one side of the face was treated with Clindamycin Gel 1% and the other side with Azithromycin Topical Gel 2% BID for 8 weeks and then they were assessed. Results: Average age was 21. 8 ± 7 years. 82.5% of them were female. Average number of papules, pustules and comedones was similarly reduced in both groups and, no significant difference was observed between the two groups (P > 0.05, repeated measurs ANOVA). The mean indexes of ASI and TLC also significantly decreased during treatment in both groups, no significant difference was observed between the two groups. (P > 0.05, repeated measurs ANOVA). Also, impact of both drugs on papules and pustules was 2-3 times greater than the effect on comedones. Average satisfaction score was not significant between the two groups (P = 0.6, repeated measurs ANOVA). finally, frequency distribution of complications was not significant between the two groups (P > 0.05, Fisher Exact test). Conclusion: Azithromycin gel has medical impact at least similar to Clindamycin Gel in treatment of mild to moderate acne vulgaris, and it may be consider as suitable drug for resistant acne to conventional topical therapy

Treatment of primary axillary hyperhidrosis by fractional microneedle radiofrequency: Is it still effective after long-term follow-up?

Background: Primary axillary hyperhidrosis (PAH) is a chronic idiopathic disorder causing major stress in patients. Among the common therapies for PAH, only surgical interventions have proven feasible as a permanent solution. Objective and Aim: The aim of this study was to evaluate the efficacy and safety of fractional microneedle radiofrequency (FMR) as an alternative permanent treatment for PAH with long-term follow-up. Materials and Methods: This was a single-blind, sham-controlled comparative study. Twenty-five patients with severe PAH were provided three treatments of FMR at 3-week intervals (the treatment group), and a control group was provided the sham treatment. Clinical efficacy was evaluated using the hyperhidrosis disease severity scale (HDSS) at baseline and the end of the study, as well as during the 1 year follow-up phase. Results: HDSS demonstrated significant improvement after treatment in the treatment group compared to the sham control. The mean (±standard deviation) of HDSS in the group being treated with radiofrequency was 2.50 (±0.88) after 1 year follow-up, and that of the control group was 3.38 (±0.49; P < 0.001). Follow-up results show that there were 10 patients (41.6%) with no relapse and 11 patients (45.9%) with relapse after 1 year. There was a significant correlation between HDSS changes in relapse and body mass index (BMI) (P = 0.03). Conclusion: Treatment of PAH with FMR is a safe and noninvasive procedure with a positive therapeutic effect on HDSS. It is recommended, however, that sessions of FMR be repeated after 1 year, particularly in overweight patients with high BMIs. Clinical Trial Registration: IRCT2013111915455N1.
