title: Trends in the frequency of original research in acne vulgaris, rosacea, dermatitis, psoriasis, skin cancer, and skin infections, 1970-2010.
abstract: BACKGROUND
  Medical journals have allowed researchers to share their latest discoveries, especially in the most common diseases affecting patients worldwide.
  
  
  OBJECTIVE
  To analyze trends in the frequency of original research into common dermatologic diseases from 1970 to 2010.
  
  
  METHODS
  A retrospective review of the Journal of the American Academy of Dermatology and the Archives of Dermatology was performed using the MEDLINE database. All original research articles published between 1970 and 2010, by quinquennium, dealing with acne vulgaris, rosacea, skin cancer, dermatitis, psoriasis, or skin infections were included.
  
  
  METHODS
  Total number of publications dealing with each dermatologic topic considered.
  
  
  RESULTS
  The frequency of research into acne vulgaris and rosacea decreased from 24% in 1970 to 5.1% in 2010. Psoriasis research increased in frequency from 17.6% to 26.5% from 2000 to 2010, and skin cancer research increased from 4% in 1970 to 48% in 2010.
  
  
  CONCLUSIONS
  Topics that experienced early advancements in research, such as acne vulgaris and rosacea, demonstrated a decreasing trend in the frequency of publication. Published psoriasis research has increased in frequency since 2000, most likely because of the discovery of biologics. Finally, skin cancer research has continued to increase in frequency of publication, paralleling the increasing incidence of skin cancer.
