RESUMO
BACKGROUND: Treatment of vascular skin diseases is one of the most important indications of the laser. AIMS: To evaluate the effectiveness of 577-nm pro-yellow laser in the treatment of some vascular skin diseases. PATIENTS/METHODS: Ninety-five patients with vascular skin diseases were included in this prospective monocentric study. They were classified into: port-wine stain birthmarks (n = 37), papulopustular rosacea (n = 20), facial telangiectasia (n = 16), and facial erythema (n = 22). All participants received a monthly session of 577-nm pro-yellow laser. Follow-up was done by comparing the photographs before and at every follow-up visit. RESULTS: At the final visit, there was a significant improvement (>50%) occurred in 24/37 (64.82%), 12/20 (60%), 10/16 (62.5%), and 19/22 (86.3%) cases and poor response occurred in 6/37 (16.2%), 2/20 (10%), 2/16 (12.5%), and 0/22 cases after a mean number of sessions 7.76 ± 2.28, 3.1 ± 1.8, 3.63 ± 1.12, and 1.8 ± 0.85 in port-wine stain, rosacea-, facial telangiectasia-, and facial erythema-treated groups, respectively. Transient irritation and erythema during the session were the only complications reported in the study. CONCLUSION: Facial port-wine stains, rosacea, telangiectasia, and erythema can be successfully treated with a single pass of 577-nm pro-yellow laser with a minimal side effect. Facial erythema showed the highest degree of success with the least number of sessions, while more sessions needed for the treatment of port-wine stain.

BACKGROUND: Erythematotelangiectatic rosasea is a common,chronic, relapsing disease characterized mainly by vascular components, for which many therapies may exist but with limited efficacy. OBJECTIVES: We decided to test the efficacy of tranexamic acid when applied topically on the affected areas.,Tranexamic acid is an antifibrinolytic,thus we considered it could be effective at this type of rosacea. METHODS: This is an unblinded study. We included 20 patients, having erythematotelangiectatic rosacea. All patients were women between 27 and 65 years-old. We divided the patients in two groups,the first group was treated only with tranexamic acid solution (Transamin inj/sol 500 mg/5 mL) infused wet dressing for 20 minutes, and the second group was treated with microneedling simultaneously with tranexamic acid solution topical application followed by tranexamic acid solution infused dressing therapy,every 15 days for four sessions. RESULTS: The improvement assecion was outlined according to the Investigator Global Assessment of Rosacea Severity Score (IGA-RSS) and the use of clinical photos and dermoscopy. All patients were improved in the end of the therapy. There was statistically significant improvement, 2 units IGA-RSS in the first group, whereas 3 units IGA-RSS in the second group. The improvement lasted more than four months. The tolerability of the use of tranexamic acid was also asessed. CONCLUSIONS: According to our results a new really promising simple, safe and cheap treatment option targeting mainly to the vascular net and the erythema of rosacea is proposed.
