Significant scientific advances have been made over the last five years in the pathogenesis of hyperuricemia and understanding how monosodium urate (MSU) crystals provoke gout. New detection methods using ultrasound (US) have been evaluated and may become part of our routine diagnostic approach in a patient presenting with gout. This review will concentrate on the latest developments in the field, and discuss how these data may impact on clinical practice. Finally, a brief review of the therapeutic implications and new therapies that have become available will be presented.
