Prevalence and risk factors of actinic keratosis in patients attending Italian dermatology clinics

2017

Background: Actinic keratosis (AK) is a common keratinocyte intraepidermal neoplasia. Objective: To assess AK prevalence and potential risk factors in patients attending Italian general dermatology clinics. Materials & methods: This retrospective study was conducted on clinical data from consecutive white outpatients aged ≥30 years, attending 24 general dermatology clinics between December 2014 and February 2015. AK prevalence (entire population) and multivariate risk factor analysis (patients with current/previous AK and complete data) are presented. Results: AK prevalence in 7,284 patients was 27.4% (95% CI: 26.4-28.4%); 34.3% in men and 20.0% in women (p<0.001). Independent AK ris…

Determination of reflectance spectra model of skin phototypes V

2012

In dermatology, skin is assessed for its response to UV light and is categorised under the Fitzpatrick skin type (FST). The FST is commonly applied as a predictor of skin cancer. The FST classification however is subjective. To enable an objective assessment, a pattern model of skin colour taken from normal subjects is required. In this paper, a model for skin phototype (SPT) V is developed and presented. We conducted an observational study involving 41 participants with FST V. The study analysed the reflectance spectra of facultative skin and constitutive skin which was captured using spectrophotometer and multispectral camera. Using piecewise linear regression, we modelled the reflectance…
