The "green nail" phenomenon in ICG-enhanced fluorescence optical imaging - a potential tool for the differential diagnosis of psoriatic arthritis.

Background And Objectives: Early diagnosis of psoriatic arthritis poses a particular challenge. A novel fluorescence optical imaging technique, the Xiralite® system is very useful in this regard as it allows for visualization of microvasculature and perfusion. The present study is the first to systematically examine fluorescence optical signals in a large psoriatic arthritis cohort.

Management of occupational Hymenoptera allergy.

Purpose Of Review: Certain outdoor activities show a particularly high risk for being stung by Hymenoptera species. Avoidance of such stings is preferable for preventing unwanted local or systemic sting reactions. The purpose of this review is to evaluate the current knowledge on risk factors and management of Hymenoptera venom allergy.
