J Drugs Dermatol. 2009 Feb; 8(2): 120-3Elewski BEA survey of people with rosacea was conducted in 2006 to gain insight into experiences with rosacea therapies and relationships with health care providers. The survey was completed by 2946 participants, of whom 2847 had been diagnosed with rosacea. Participants ranged in age from 20 to 81 years (mean age 50 years). Among those diagnosed with rosacea, 80% agreed that medication prevented their rosacea from worsening. Most respondents currently using prescription medication (82%) did not plan to discontinue its use. Among current users of medication, 46% had switched from a prior agent, usually due to the lack of improvement. Among respondents who previously switched therapies, 84% reported using some formulation of topical metronidazole. Of those respondents who discussed rosacea with their physician, 83% agreed that their physician influences their use of medication; 61% viewed their physician-in most cases a dermatologist-as a partner in managing their rosacea.
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...
