European trends in the frequency of original research in acne vulgaris, rosacea, dermatitis, psoriasis, skin cancer, and skin infections, 1970-2010.

We analyzed trends in the frequency of original publications into common dermatologic topics in two premier European journals, the British Journal of Dermatology and the Journal of the European Academy of Dermatology and Venereology. Most notably, we found that psoriasis publications peaked around the mid-to-late 1980's as well as demonstrated an upward trend since the 21st century. Skin cancer research witnessed a gradual increase in the frequency of publications since 1970. These findings were consistent with a prior study analyzing trends in two American dermatology journals. We attempted to analyze these results from a historical perspective as well as provide an outlook on the future of research into these common dermatologic topics.
