Septic Arthritis • Common joints involved: • Adult: Knee, wrist, ankle • Children: Knee, Hip • IVDU: axial skeleton (vertebral, SI, sternoclav) • Risk Factors: • Very old and young • Chronic debilitating disease • IVDU • Immunosuppressive therapy • Prosthetic joint or post arthrocentesis
Septic Arthritis • Joint aspiration: • A must do!!!! KNEE: Extend knee, insert needle from the medial side between posterior surface of the patella and intercondylar femoral notch at midpoint to superior pole of the patella WRIST: Flex wrist with ulnar deviation. Insert needle distal to Lister’s tubercle ulnar to extensor pollicus longus
Septic Arthritis ELBOW Flex elbow . Insert needle from lateral side distal to lateral epicondyle and direct medially ANKLE Plantar flex foot. Insert needle into hollow at anterior edge of the medial malleolus medial to anterior tibial tendon. Will have to insert needle 2-3 cm NORMAL SYNOVIAL FLUID ANALYSIS Clear < 200 WBC/mm3 < 25 PMN no crystals
Septic Arthritis • Management: • Non-prosthetic joint: • Daily aspiration • Iv Ancef for 3 weeks • Prosthetic joint • Daily aspiration or I&D • IV vancomycin and po Ciprofloxacin
Gout • Risk factors: • Obesity • Hypertension • Diabetes • Alcohol consumption • Loop diuretics • Lead exposure
Gout • Management: • NSAIDs: • Indomethacin 50 mg tid X 3-5 days • Colchicine: • 0.6 mg q1h until pain subsides max 4-6 mg • Side Effects: GI upset, • Steroids • If resistant to above; 40 mg qd X 3-5 days

Lyme disease • Treatment: • Shortens duration of symptoms and prevents later disease • Doxycycline 100mg bid X 2-4 weeks • Amoxicillin 500mg tid X 2-4 weeks (pregnant and lactating women, children < 5 yrs)
Reiter’s Syndrome • Reactive arthritis from GI/GU infections (Chlamydia, Shigella, Salmonella, Yersinia, Campylobacter) • Asymmetric polyarthritis mainly of weight bearing joints ~ 2-6 weeks post urethritis or dysentery
Reiter’s Syndrome • Physical exam: • Polyarthritis • Ocular findings (conjuntivitis, uveitis, corneal ulcers) • Oral ulcers (10% of patients) • Sores on glans penis (20% patients) • Saugelike fingers and toes • Low back pain
Reiter’s syndrome • Management: • Indomethacin up to 250 mg/d • If Chlamydial tetracylines may shorten duration • Will last 4-7 months • May be recurrent
Bursitis & Tendinitits • Shoulder – major causes of pain: • Subacromial bursitis, supraspinatuns tendinitits, bicipital tendinitis, rotator cuff • Elbow • Lateral epicondylitis, olecranonbursitis • Hip • Trochanteric, ischial, iliopsoas bursitis • Knee • Prepatellar, infrapatellar, anserine bursitis
Bursitis & Tendinitis MANAGEMENT • Conservative • Ice, rest, NSAID’s • Early ROM exercises for shoulder and elbow • Olecranon and prepatellar bursitis • Aspirate • Cefazolin 1g iv q8hr
Malar rash Discoid rash Photosensitivity Oral ulcers Arthritis Serositis Pleuritis Percarditis Renal disorder Neurologic disorder Seizures Psychosis Hematologic disorder Anemia Leukopenia Thrombocytopenia Blood tests ANA, anti-Sm Ab, anti-DNA Ab, False + VDRL/RPR SLE – the diagnosis (need > 4)
SLE - treatment • NSAID’s : first line (don’t use if low platelets, GI involvement, renal disease) • Corticosteroids: • Minor: Prednisone 0.5 mg/kg/d • Major: Prednisone 1g/kg/d • Cerebritis or worsening glomerulonephritis: methylprednisolone 1 g iv • Antimalarial • Immunosuppression agents
Cyclophosphamide Hemorragic cystitis Bladder carcinoma SIADH GI distress Alopecia Myelosuppression Neoplasia Infection Azathioprine GI distress Myelosuppression Hepatitis Pancreatitis Aseptic meningitis Neoplasia Infection SLE – complications of immunosuppressive agents
Drugs that can cause a Lupus-like Syndrome • Procainamide • Quinidine • Hydralazine • Isoniazid • Penecillin • Sulphonamides • Tetracycline • Dilantin • And the list goes on…..
Vasculides Wegener’s • Medium vessel disease • Upper resp tract, Lower resp tract, then glomerulonephritis (85%), ocular findings and cerebral vasculitis (33%) • Diagnosis: elevated ESR, + c-ANCA, - ANA, hematuria, active urine sediment • CXR: sharply demarcated pulmonary nodules • Management: steroids & cyclophosphamide, iv steroid for flares of glomerulonephritis
Vasculides Henoch-Schonlein Purpura • Usually affects children • Triggers: viral infections, insect stings, drugs • Presentation: purpuric rash, lower limb arthralgia, GI complaints (80%), gomerulonephritis (50%) • Management: conservative, severe arthralgia or abdo pain give 1mg/kg/d prednisone, admit with iv steroids if renal involvement
