Reactive arthritis: the convoluted history of Reiter's disease.

Reactive arthritis, previously known as Reiter's Syndrome or Disease was a post-dysenteric, asymmetrical acute large joint polyarthritis, with fever, conjunctivitis, iritis, purulent urethral discharge, rash and penile soft tissue swelling. Although the eponym was given to Hans Reiter, various forms of the condition have been recorded in history a few hundred years before Reiter. Two French doctors, Noel Fiessinger (1881-1946) and Edgar Leroy (d. 1965), presented a paper at la Societe des Hopitaux-in Paris on the 8th December 1916 on dysentery in 80 soldiers on the Somme, and four of whom developed a "syndrome conjunctivo-uretro-synovial". Their paper was given 4 days before Reiter's presentation on 12th December 1916 at the Society of Medicine in Berlin, on a German army officer with an illness similar to those described by Fiessinger and Edgar Leroy. It is documented that Hans Reiter was one of a number of University professors who signed an oath of allegiance to Adolf Hitler in 1932. For socio-ethical reasons and for clinical utility, Reiter's syndrome is now known as reactive arthritis.
