ACUTE MONOARTHRITISBERGER’S B’S • BUGS • BLOOD • BIREFRIGENCE
CALCIUM PYROPHOSPHATE (cppd) • Acute pseudogout • Female predominant • Knees/Shoulders/Wrists/MCP’s • High fever and sed rate possible • Can coexist in same joint with true infectious etiology: Unlike gout
CALCIUM HYDROXYAPATITE • “Milwaukee Shoulder” • Shoulders/knees/hips • Hemarthrosis associated • Rotator cuff destruction • Fever and high sed rate less common than in CPPD
Musculoskeletal Presentations of Infectious Diseases • Known systemic infectious diseases with musculoskeletal presentations • Probable infectious agent causing systemic rheumatic disease
Post Streptococcal Arthritis(Rheumatic Fever) • Shoulder “periarthritis” (80% in Persellin series in 1970’s) • Classical migratory large joint synovitis rare • Nodules/Carditis/Athetosis rare • E nodosum more common than E marginatum
Gonorrhea • Monoarticular/Pauciarticular synovitis: Large joint predominance • Recovery of organism from joint 10% or less. Smears negative • When recovered from joint, Rx the same as Staph septic joint: Recurrent aspirations
KAWASAKI DISEASE • Fever lasting at least 5 days • Bilateral conjunctivitis • Oral mucous membrane changes • Peripheral extremity changes • Polymorphus rash • Cervical lymphadenopathy • Lab markers of inflammation
KAWASAKI DISEASE • Inflammatory Arthritis: 15-25 % • Diarrhea/Abd pain: 50% • Cough: 35 % • CORONARY ARTERITIS WITH ANEURYSMS: ? 100% ACUTELY • IVIG AND ASA!!!
Parvovirus: B19 • Rheumatoid Arthritis look alike: Symmetrical Polyarthritis involving hands/wrists/knees/feet • + RF and ANA 20-30% • + cryoglobulins • 6 month course • Steroids occasionally required
HEPATITIS B • Symmetrical polyarthritis:small joints • Sometimes Urticarial rash • Prodrome to jaundice • Low serum complements • Sometimes with glomerulonephritis
RUBELLA • Large joint oligoarthropathy almost always involving knees • Can last months • Chronic RA look alike described after initial infection • Can occur after immunizations
LYME DISEASE • True arthritis tertiary manifestation • Arthralgia common in secondary stage • Pauciarticular large joint arthopathy • Thought intially to be JRA • One mother and local PTA + YALE
REACTIVE ARTHRITIS SYNDROME • 90% with preceding chlamydial infection vs. bowel pathogen • Also described after Chlamydia Pneumonia and Mycoplasma Pneumonia • Chlamydial antigen demonstrated in synovium in involved joints • ?? Controls • ?? Immunological mechanism
LOFGRENS SYNDROME • Acute Histoplasmosis/Sarcoidosis • Fever • Erythema Nodosum • Ankle Periarthritis • Hilar Adenopathy • Occasional uveitis/parotitis • Usually resolves without sequelae
GIANT CELL ARTERITIS • Temporal /Takayasu’s arteritis • Old Scandinavian women vs. young Japanese/Israeli/Mexican women • Carotid vs. aortic arch circulation • Systemic symptoms: FUO presentation • Symmetrical polyarthritis: 10% • Sed rates!!!!!!!! • Parvovirus anectdotes: Mayo data
BEHCET’S SYNDROME • Painful oral and genital ulcers • Uveitis: Anterior and posterior • “Pathergic” skin rash • Aseptic meningitis • Hypercoaguability • Pulmonary arterial aneurysms • TNF excess: Therapeutic options
Relapsing Polychondritis • True cause of ER Dx of costochondritis • Chondritis/scleritis/vasculitis • Fever and arthritis • Palpable purpura • Subglottic stenosis • Tracheal collapse • Rx with steroids and immunosuppresion
