Photodynamic Therapy and Non-Melanoma Skin Cancer.

Non-melanoma skin cancer (NMSC) is the most common malignancy among the Caucasian population. Photodynamic therapy (PDT) is gaining popularity for the treatment of basal cell carcinoma (BCC), Bowen's disease (BD) and actinic keratosis (AK). A topical or systemic exogenous photosensitiser, results in selective uptake by malignant cells.

Assessment of "corticophobia" as an indicator of non-adherence to topical corticosteroids: A pilot study.

Background: Concerns regarding topical corticosteroid (TCS) use, broadly known as "corticophobia", are highly prevalent among dermatology patients and often result in non-adherence to TCS. This non-adherence contributes to poor disease control and increased health care costs. However, it is unknown if assessment of these concerns might help to identify patients at risk of TCS-non-adherence.

Non-melanoma skin cancer.

Non-melanoma skin cancer (NMSC) comprises basal cell carcinoma (BCC) and squamous cell carcinoma, together with a host of rare tumours. NMSC is the commonest malignancy among Caucasians and its incidence continues to rise annually. Exposure to UV radiation initiates approximately 90% of NMSC, causing malignant transformation of keratinocytes and suppression of the inflammatory response.
