Photodermatoses are skin disorders induced or exacerbated by light. They can be broadly classified into four groups: (i) immunologically mediated photodermatoses (idioapathic); (ii) drug- and chemical-induced photosensitivity; (iii) defective DNA repair disorders; and (iv) photoaggravated dermatoses. The exact pathomechanism of those diverse skin reactions to light radiation remains unclear. ⋯ The management of photodermatoses starts with clinical recognition of characteristic lesions localized predominantly in light exposed skin. Detailed history-taking, phototesting and photopatch testing are required to establish a correct diagnosis, especially if patients present in disease-free intervals. Classification and short description of distinctive clinical features of most common photodermatoses, several practical aspects of evaluation and management of the patient with photosensitivity will be outlined.

CONSORT (Consolidated Standards for Reporting Trials) guidelines were constructed to ensure optimal reporting quality of randomized controlled trials (RCTs). ⋯ There is a need to improve the reporting quality of RCTs published in dermatology journals.

Multicenter Study
Inpatient management of patients with skin cancer in Germany: an analysis of the nationwide DRG-statistic 2005-2006.
In 2004, Germany introduced a nationwide DRG (Diagnosis Related Groups) based recompensation system for hospitals. The aim of this study was to provide nationwide quantitative information about the in-hospital management of skin cancer patients in Germany based on the DRG statistic of the years 2005 through 2006. ⋯ We provide for the first time nationwide quantitative data on the in-hospital management of skin cancer patients. The observed differences in the management of MEL and NMSC most likely reflect differences of the biology, epidemiology and therapeutic modalities of these cancers.

Little is known about brain mechanisms supporting the experience of chronic puritus in disease states. ⋯ Our results demonstrate that ASL fMRI is a promising technique to assess brain activity in chronic itch. Brain activity of acute itch in AD seems to differ from that in healthy subjects. Moreover, the activity in cortical areas involved in affect and emotion correlated to measures of disease severity.

Skin cancers represent a major challenge within the ever growing group of long time surviving organ transplant recipients (OTR) world wide. Especially UV-induced non-melanoma skin cancers (NMSC) like invasive squamous cell carcinomas (SCC) and actinic keratoses (AK), and basal cell carcinoma (BCC), outnumber every other form of cancer in organ transplant recipients. Despite encouraging reports of protective effects of broad-spectrum sunscreens in immunocompetent patients, evidence for the prevention of NMSC in immunocompromised patients is still missing. ⋯ Regular use of sunscreens, as part of a consequent UV-protection strategy, may prevent the development of further AK and invasive SCC and, to a lesser degree, BCC in immune-compromised organ transplant recipients.
