Infections commonly associated with reactive arthritis fall into 2 groups:
- GI infections
- campylobacter
- salmonella
- yersinia
- shigella
- GU infections
- chlamydia
- gonnorhora
- ureaplasma
The classical triad associated with reactive arthritis is Reiters Syndrome of uveitis/conjunctivitis, urethritis and arthritis ("can't see, can't pee, can't climb a tree") Apparently in some parts this is becoming a politically incorrect term as Dr Reiter was a member of the Nazi party with a less than perfect record by the 1940s...
Reactive arthritis can also be associated with keratoderma blenorrhagica, which is brown raised plaques on the hands and feet. Rarely it can cause aortic incompetance.
Treatment is generally resting/splinting the affected joint and NSAIDS.
Now time for some diversification to the liquid world of the pleural effusion....
