Hello and welcome to the zero to finals podcast.

My name is Tom and in this episode I'm going to be talking to you about

And you can find written notes on this topic at zero to finals.com slash

It's associated with extra articular manifestations, meaning problems away from the joints, particularly uveitis, which

Asymmetrical oligoarthritis affects one to four joints at any given time, often only on one side of the body.

Symmetrical polyarthritis presents similarly to rheumatoid arthritis.

More than four joints are affected, such as the hands, wrists and ankles.

The third pattern is called distal interphalangeal predominant pattern,

which primarily affects the DIP joints or distal interphalangeal predominant pattern, which primarily affects the DIP joints or distal
