The pulsed dye laser is a device that selectively targets oxyhemoglobin with proved efficacy in the treatment of vascular lesions, especially at purpuric doses. Objective: We decided to evaluate the impact of the pulsed dye laser on rosacea patients' quality of life using the Dermatology Life Quality Index (DLQI) score. Methods: Twenty-two patients with erythematotelangiectatic rosacea were enrolled in the study. They were asked to complete a DLQI questionnaire before and after three treatments. Erythema improvement was subjectively evaluated by two investigators who ranked it as equal, better or worse after the three treatments. Results: A statistically significant improvement was observed in the DLQI score after three treatment sessions. All patients were judged by the investigators to have improved facial erythema. Conclusion: This study reinforces the idea that pulsed dye laser usage for the treatment of erythematotelangiectatic rosacea is very efficient, emphasizing that it also has the ability to improve rosacea patients' quality of life.
To estimate the prevalence of dry eye and to investigate its relationship with lifestyle and systemic factors in a general adult population in north-western Spain. METHODS: A dry eye questionnaire was administered and objective tests were performed in 654 individuals [mean age (Standard deviation): 63.6 (14.4) years, range: 40-96, 37.2% males]. Subjects were considered symptomatic when one or more of the symptoms of the questionnaire were present often or all the time. Schirmer test or= 3 and fluorescein staining >or= 1 were considered indicative of signs. Dry eye was defined as the simultaneous presence of symptoms and at least one sign. A design based analysis was performed and all calculations were weighted to give unbiased estimates. RESULTS: Dry eye prevalence was 11.0% (95%confidence interval [CI] 8.6-13.3). Dry eye was found to be more frequent in women (11.9%, 95%CI 8.8-15.1) than in men (9.0%, 95%CI 5.3-12.6), and was significantly associated with aging (p autoimmune diseas...
