Prevalence of precancerous skin lesions and non-melanoma skin cancer in Japanese-Brazilians in Bauru, São Paulo State, Brazil

Prevalence of actinic keratosis among dermatology outpatients in Austria

“…In order to develop such strategies, reliable epidemiological information would be desirable, particularly in relation to the prevalence of AK and the accessibility of the affected population. Regretfully, data about AK prevalence are sparse, and originate mostly from Australia and the U.S.A., 3,4,[17][18][19][20][21][22] with only a few such studies available from Europe [13][14][15]23,24 and Asia [25][26][27][28] and no information from Africa and South America. The aim of this study is to define the prevalence of AK in adult dermatology outpatients in Austria.…”

In vivo Confocal Laser Microscopy for monitoring of actinic keratosis treatment: a comparison with histopathologic assessment after treatment with topical 5% 5‐fluorouracil

“…AK prevalence is higher in warmer climates – its prevalence ranges from 2.7% (16–70 years) in Germany to 50% (30–69 years) in Australia . Epidemiological studies in Brazilian population are limited; a previous study performed in Bauru, São Paulo, found a prevalence of 13.4% in a Japanese–Brazilian sample …”

“…4 Epidemiological studies in Brazilian population are limited; a previous study performed in Bauru, São Paulo, found a prevalence of 13.4% in a Japanese-Brazilian sample. 5 Clinically, these lesions are presented as erythematous or flesh coloured, scaly papules or plaques with a gritty, sandpaper-like texture with less than one centimetre in diameter. 1,3,6 Common body sites affected are head, bald or balding scalp, face, back of arms and hands.…”

Should variation of serum lipid levels be considered a risk factor for the development of basal cell carcinoma?

“…[1] The history of childhood sunburn and intermittent exposure to sunlight has an important role in increasing its incidence. [23] The incidence of BCC also increases with age.…”

“…[4] Apart from the exposure to ultraviolet radiation, which is the single most important risk factor for developing skin cancers,[5] there are some other known risk factors such as lymphoma/leukemia, AIDS and other immune-compromised conditions, radiotherapy, X-ray exposure, arsenic toxicity, infection with human papilloma virus, stasis dermatitis, scar due to thermal burn and Plus long-wave ultraviolet light (PUVA) therapy. [16] Alterations in plasma lipids and lipoproteins have been reported in association with some skin cancers. [7] Additionally, more content of phospholipids and cholesterol in cancerous and pre-cancerous lesions of the skin have been found compared with normal tissue.…”
