We suggest that CO(2) FS used with a combination of two different treatment modes may provide a new treatment algorithm for acne scars in Asians.

Patients with primary premature ejaculation have penile hypersensitivity, which provides further implications for an organic basis of premature ejaculation.

Introduction Mirodenafil is a newly developed oral phosphodiesterase type 5 inhibitor, currently under investigation as a treatment for erectile dysfunction (ED). Aim We investigated the efficacy and safety of on demand mirodenafil therapy at fixed doses (50 and 100 mg) in Korean men with a broad range of ED. Methods A multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study was conducted with 223 subjects who were randomized to placebo or mirodenafil at fixed doses of 50 or 100 mg for 12 weeks on an “as needed” basis. Main Outcome Measures Primary efficacy measures were scores on the International Index of Erectile Function (IIEF) Question 3 (Q3) and Question 4 (Q4). Secondary efficacy measures included all domain scores of the IIEF, Sexual Encounter Profile Question 2 (SEP2), Sexual Encounter Profile Question 3 (SEP3), the Global Assessment Question (GAQ), and the Life Satisfaction Checklist (LSC). Safety assessments included laboratory tests, vital signs, physical examination, 12-lead electrocardiogram recordings, and patients’ reporting of adverse events. Results Mirodenafil 50 and 100 mg groups showed a significantly greater increase in IIEF Q3 (P = 0.0001, P < 0.0001, respectively) and Q4 scores (both P < 0.0001) at the end point compared with the placebo group. And mirodenafil in both doses significantly improved the scores of all five domains of the IIEF, SEP2, and SEP3 as well as the percentages of patients responding positively to the GAQ compared with the placebo group. As for LSC scores, the two mirodenafil groups showed significantly greater improvements in items regarding life as a whole, sexual life, and partner relationship than the placebo group. Most treatment-associated adverse events were of mild intensity, resolving spontaneously. Conclusions Mirodenafil, in doses of 50 or 100 mg, significantly improved erectile function and were well tolerated in a representative population of Korean men with broad-spectrum ED of various etiologies and severities.

Study Type – Therapy (RCT) Level of Evidence 1b What's known on the subject? and What does the study add? Avanafil is a potent selective phosphodiesterase type 5 (PDE5) inhibitor newly developed for treating erectile dysfunction (ED). Preclinical and clinical phase I studies showed that avanafil had enhanced selectivity, faster onset of action and a favourable side‐effect profile relative to currently available PDE5 inhibitors. As the result of phase III clinical trial for the efficacy and safety of avanafil treatment (100 and 200 mg), taken as needed over a period of 12 weeks, in Korean patients with ED, avanafil is an effective and well‐tolerated therapy for ED of broad‐spectrum aetiology and severity. OBJECTIVE To evaluate the efficacy and safety of avanafil, a new potent selective phosphodiesterase type 5 (PDE5) inhibitor, in patients with erectile dysfunction (ED). PATIENTS AND METHODS The present study was a multicentre, randomized, double‐blind, placebo‐controlled, fix‐dosed phase three clinical trial involving 200 patients with ED. The subjects were treated with placebo or avanafil (100 or 200 mg) for 12 weeks and were asked to complete the International Index of Erectile Function (IIEF), the Sexual Encounter Profile (SEP) diary, and the Global Assessment Questionnaire (GAQ). The primary outcome variable was the change from baseline for IIEF erectile function domain (EFD) score. The secondary outcome variables were SEP Q2 and Q3, the shift to normal rate (EFD ≥ 26), and response to the GAQ. RESULTS Compared with placebo, patients who took 100 or 200 mg of avanafil had significantly improved IIEF‐EFD score. There were similar results when comparing Q2 and Q3 in the SEP diary and the GAQ. Flushing was the most common treatment‐related adverse event. Most adverse events were transient and mild or moderate in severity. CONCLUSION Avanafil is an effective and well‐tolerated therapy for ED of broad‐spectrum aetiology and severity.

Fractionated microneedle RF can have a positive therapeutic effect on inflammatory acne vulgaris and related scars. In addition, this technique does not worsen active acne lesions.
