J Drugs Dermatol. 2009 May; 8(5): 459-62Ortiz A, Elkeeb L, Truitt A, Hindiyeh R, Aquino L, Tran M, Weinstein GBACKGROUND: Current treatments for acne rosacea are often associated with unsatisfactory outcomes and adverse effects. OBJECTIVE: To determine the efficacy and tolerability of a new moisturizing lotion for improving the clinical signs and symptoms of mild-to-moderate acne rosacea. METHODS: In a 12-week, open-label study, a moisturizing lotion containing furfuryl tetrahydropyranyladenine as PRK124 (0.125%, Pyratine-XR, Senetek PLC, Napa, CA) was applied twice daily to subjects with mild-to-moderate rosacea. Improvement in the appearances of erythema and papules were assessed by the treating physician. Skin barrier function was measured by transepidmal water loss after treatment. Tolerability and cosmetic outcome were evaluated by patients. RESULTS: Twenty-one participants completed the study. Overall clinical improvement was observed in 80% of subjects, with most showing mild-to-moderate improvement. Erythema, papule counts, and telangiectasia were reduced. The reduction in TEWL was significant at weeks 4 (p = 0.01), 8 (p < 005), and 12 (p < 0.001). Rosacea symptoms (burning, stinging, dryness) were progressively reduced, with reduction in dryness achieving statistical significance at weeks 4 (p = 0.035), 8 (p = 0.037) and 12 (p = 0.016). Treatments were well tolerated and cosmetic outcomes were acceptable. Treatment-induced irritation was not observed. CONCLUSION: The new moisturizing lotion containing furfuryl tetrahydropyranyladenine as PRK124 shows a continued trend toward improvement of skin barrier function and the appearances of erythema and papules associated with mild-to-moderate rosacea during 12 weeks of treatment.
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...
