How do you confirm the diagnosis of Gout?

First line acute treatment for Gout?
(3)
Local steroid injection
Prednisolone 15-30mg daily for 3-5 days, taken orally
Higher dosing of NSAIDs, orally, until symptoms resolve.
Second line treatment for acute gout?
Colchicine 1mg orally, immediately, then 500micrograms 1 hour later, orally.

What is the recommended gout prophylaxis and how do you adjust the dosing?
Allopurinol started at 50mg daily for 4 weeks, taken orally. And increase by 50mg every 2 weeks to achieve target urate level.
Target urate level is under 0.36 for non tophaceous gout and under 0.3 for tophaceous gout
Maximum dose is 900mg a day
Consider flare prophylaxis for up to 6 months
First line: colchicine 500micrograms, orally once or twice a day
