Cutis. 2008 Dec; 82(6 Suppl): 2-16Ditre C, Wu J, Baumann LS, Rigel DThe use of natural products for skin care has become more common in the past few years. Consumers are more aware of unnatural chemicals and other toxins and are searching for natural products to use on their skin. Fortunately, a large number of botanical antioxidants exist and are being marketed as either over-the-counter or prescription skin care products. Antioxidants can have profound effects on the intracellular signaling pathways involved in skin damage and thus may be protective against photodamage as well as may prevent wrinkles and inflammation. This supplement discusses the potent effect that botanical antioxidants may have in the management of a broad range of skin issues, from photoaging to inflammatory skin conditions.
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...
