Gout: Rapid Evidence Review [Article]

Risk factors of gout include male sex; obesity; hypertension; alcohol intake; and a diet rich in meat, seafood, and fructose-rich food and beverages. Gout is characterized by swelling, pain, or tenderness in a peripheral joint or bursa. Diagnosis is made using several validated clinical prediction rules. Arthrocentesis should be performed when suspicion for an underlying septic joint is present; synovial fluid or tophus analysis should be performed if the diagnosis is uncertain. Colchicine, nonsteroidal anti-inflammatory drugs, and corticosteroids all relieve pain in acute episodes. Indications for chronic urate-lowering therapy include chronic kidney disease, two or more flares per year, urolithiasis, the presence of tophus, chronic gouty arthritis, and joint damage.

Short-Term Systemic Corticosteroids: Appropriate Use in Primary Care [Article]

Short-term systemic corticosteroids are frequently prescribed for adults by primary care physicians; however, short courses of the steroids are associated with adverse effects, including hyperglycemia, elevated blood pressure, mood disturbance, sepsis, and fracture. There is evidence against corticosteroid use in patients with acute bronchitis, acute sinusitis, carpal tunnel, and allergic rhinitis and for its use in patients with Bell palsy and acute gout. There is insufficient evidence supporting its use for patients with pharyngitis, lumbar radiculopathy, and herpes zoster.

Clinical Diagnosis of Gout Without Joint Aspirate [Point-of-Care Guides]

Gout is ideally diagnosed through identification of characteristic negatively birefringent crystals under polarized light microscopy in fluid aspirated from end-organ deposits, typically from a joint. However, fewer than 10% of patients with gout see a rheumatologist, and most cases of gout are diag...
