Gout

Description

Gout is an acute or chronic arthropathy resulting from deposition of monosodium urate monohydrate crystals in joint tissues. It is strongly associated with hyperuricaemia, which may be secondary to certain drugs, poisons or lymphoproliferative disorders. Gout is definitively diagnosed by demonstration of urate crystals in aspirated synovial fluid in the absence of an alternative aetiology for arthritis. It may be associated with focal urate deposition in skin and subcutaneous tissue (tophaceous gout) and with urate nephropathy
