Translation and Validation of the Dutch Version of the Sun Exposure and Protection Index.

Introduction: Skin cancer is currently the most common cancer type worldwide, and numbers are rapidly increasing. To improve primary prevention, individualised prevention strategies may be of interest as this enhances the chance of long-term behavioural change. The Sun Exposure and Protection Index (SEPI), previously validated in multiple languages, is a tool that could help identify individuals with risky behaviour and tailor interventions to the person's propensity to change.

Single Cell Genetic Profiling of Tumors of Breast Cancer Patients Aged 50 Years and Older Reveals Enormous Intratumor Heterogeneity Independent of Individual Prognosis.

Purpose: Older breast cancer patients are underrepresented in cancer research even though the majority (81.4%) of women dying of breast cancer are 55 years and older. Here we study a common phenomenon observed in breast cancer which is a large inter- and intratumor heterogeneity; this poses a tremendous clinical challenge, for example with respect to treatment stratification.

Biopsy outperforms reflectance confocal microscopy in diagnosing and subtyping basal cell carcinoma: results and experiences from a randomized controlled multicentre trial.

Background: Reflectance confocal microscopy (RCM) is a noninvasive method for skin assessment, allowing entire lesion evaluation up to the papillary dermis. RCM is a potentially attractive alternative to punch biopsy (PB) in basal cell carcinoma (BCC).

Objectives: To determine the diagnostic accuracy of RCM vs.

[Minocycline-induced hyperpigmentation: not uncommon, but nonetheless important to recognise].

Background: Minocycline, a broad-spectrum antibiotic from the group of tetracyclins, is frequently prescribed for acne vulgaris and rosacea. Hyperpigmentation is a relatively common side effect of this drug and can lead to multiple unsightly skin lesions, which are not always reversible. It can take a long period, from a few months to several years, before the lesions have completely vanished.

Diagnosis of Basal Cell Carcinoma by Reflectance Confocal Microscopy: Study Design and Protocol of a Randomized Controlled Multicenter Trial.

Background: Skin cancer, including basal cell carcinoma (BCC), has become a major health care problem. The limitations of a punch biopsy (at present the gold standard) as diagnostic method together with the increasing incidence of skin cancer point out the need for more accurate, cost-effective, and patient friendly diagnostic tools. In vivo reflectance confocal microscopy (RCM) is a noninvasive imaging technique that has great potential for skin cancer diagnosis.
