  2. 6. Assessment of UV exposure in a young metropolitan population

    Author : Cecilia Boldeman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adolescents; Behaviors; Erythema; Phenotype; Skin cancer; Sunbed use;

    Abstract : Overexposure to UVR causes >80% of skin cancers, and >30% of all diagnosed cancers in western societies, Sweden included, are skin cancers. Overexposure in terms of UV-induced erythema during childhood and adolescence is considered particularly harmful. READ MORE

  4. 7. UV-induced DNA damage in humans

    Author : Vladimir J Bykov; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 32P-HPLC; photoproducts; DNA repair; solar simulated radiation; erythema; sunscreens; humans;

    Abstract : Ultraviolet radiation is considered to be the most harmful part of solar energy affecting man. The depletion of the ozone layer around the Earth increases the total exposure to UV-light. The incidence of skin cancer in man has been shown to be associated with exposure to solar radiation, especially to UV-light. READ MORE

    Keywords : Vulvar vestibulitis syndrome; immunohistochemistry; QST; COX 2; NOS; laser Doppler perfusion imaging; intraepithelial nerve fibres; pain thresholds; sensory stimulation.;

    Abstract : Objective: The main purpose of the study was to survey possible pathophysiological changes of the vestibular mucosa in women with vulvar vestibulitis syndrome with regard to the clinical findings of superficial dyspareunia and mucosal erythema. Methods: Biopsies analysed with immunohistochemistry were used to study the morphology, distribution and neuropeptide content of the peripheral nerves, and the microvascularisation of the vestibular mucosa.

    Author : Margareta Lindgren; Christina Lindholm; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The aims of this thesis were to study the prevalence, incidence, prevention and treatment of pressure sores, to further develop a risk assessment scale, and test the reliability and validity of this scale, to identify risk factors for pressure sore development, and to study skin blood flow in non-blanchable erythema areas as compared to undamaged skin.Criteria used for pressure sore assessment were persistent discoloration i.
