    Sunscreen use and sun protection practices in students and personnel of Celal Bayar University
    (2005) Ermertcan A.T.; Öztürkcan S.; Dinç G.; Yurtman D.; Pala T.; Şahin M.T.
    Background/Purpose: The steady increase in the incidence of melanoma, non-melanoma cutaneous neoplasia and preneoplastic disorders has contributed to the demand for more effective protection from the sun. In this study, we aimed to determine the prevalence of sunscreen use and other sun protection behaviors in a large sample of students and personnel of Celal Bayar University, Manisa, Turkey. Methods: The study group included 1018 participants of whom 607 work in the Celal Bayar University Hospital and 411 are students from the Medical Faculty and School for Health Professionals. All participants completed a questionnaire composed of 45 items about sun protection and other health behaviors, such as sports activity, use of cigarettes, alcohol and seat-belts. Sun protection factor (SPF) of sunscreen, avoiding sun exposure during peak hours, wearing clothing, a hat and sunglasses were studied. Results: Of the 1018, 403 participants were male and 615 were female. While avoiding sun exposure during peak hours was the most popular preventive behavior for men (42.5%), wearing sunglasses was the most popular one for women (50.7%). Avoiding exposure was the second preventive behavior for women (42.1%). Use of sunscreen with SPF 15+ was the second popular protective measure for men (19.4%) and the third one for women (39.2%). There were no significant relationships between sun protection behaviors and obesity, use of cigarettes and alcohol. We also investigated behavioral changes with sunburn experience in the participants who had sunburn history. Among these behavioral changes, increased use of sunscreen and decreased sun exposure during peak hours with sunburn experience were significant. Conclusion: Our study demonstrated that the risk of sun exposure is largely unrecognized in Manisa, Turkey, and we have very incomplete information about protective measures. An efficient policy of education on the effective use of sun protection methods should be developed to prevent skin cancer. Copyright © Blackwell Munksgaard 2005.

    Chronic actinic damage of facial skin
    (Elsevier Inc., 2014) Bilaç C.; Şahin M.T.; Öztürkcan S.
    Chronic actinic damage of the skin manifests itself as extrinsic skin aging (photoaging) and photocarcinogenesis. During the last decade, substantial progress has been made in understanding cellular and molecular mechanisms of photoaging. DNA photodamage and ultraviolet-generated reactive oxygen species are the initial events that lead to most of the typical histologic and clinical manifestations of chronic photodamage of the skin. Chronic actinic damage affects all layers of the skin. Keratinocytes, melanocytes, fibroblasts, and endothelial cells are altered by ultraviolet radiation and can result in numerous changes in human skin, particularly the skin of fair-skinned individuals. These changes include actinic keratosis, thickening and wrinkling, elastosis, telengiectasia, solar comedones, diffuse or mottled hyperpigmentation, and skin cancers. There are many options in the treatment of changes caused by chronic actinic damage. The most effective measure of prevention of the photoaging and photocarcinogenesis is sun protection. © 2014 Elsevier Inc.
