Q1: Recognition & definition (2 min)
A young man presents with asymmetric lower-limb oligoarthritis 1-4 weeks after diarrhoea or a genital infection. Define reactive arthritis. Why is the joint "sterile"? Where does the term Reiter syndrome fit, and why is it discouraged?
Q2: Triggers & pathophysiology (3 min)
Name the genitourinary and gastrointestinal triggers. Discuss the role of HLA-B27 and the IL-17/23 axis. Why do antibiotics not shorten the arthritis course?
Q3: Clinical features & differential (2 min)
Describe the Reiter triad and the musculoskeletal and mucocutaneous manifestations (keratoderma blennorrhagicum, circinate balanitis, dactylitis, enthesitis). How do you distinguish reactive arthritis from septic, gonococcal, gout and psoriatic arthritis?
Q4: Management & complications (3 min)
Outline first-line and escalation therapy (NSAIDs, intra-articular steroids, sulfasalazine/DMARDs, TNF inhibitors). When is ophthalmology urgent (uveitis vs conjunctivitis)? Discuss prognosis and chronic disease.
