Systemic Lupus Erythemаtоsus (SLE) Bаckgrоund A chrоnic, multisystem аutoimmune disease characterized by autoantibody formation and immune complex deposition. Predominantly affects women of childbearing age (female:male ratio ~9:1). Higher prevalence in African American, Hispanic, and Asian populations. Symptoms Constitutional: fatigue, fever, weight loss. Musculoskeletal: symmetric, nonerosive arthritis (MCP, PIP, knees). Skin: malar (“butterfly”) rash, discoid lesions, photosensitivity, oral/nasal ulcers, alopecia. Renal: lupus nephritis (proteinuria, hematuria (red blood cell casts), hypertension). Neuro: seizures, psychosis, headaches, cognitive dysfunction. Cardiopulmonary: pericarditis, pleuritis, restrictive lung disease. Hematologic: anemia of chronic disease, hemolytic anemia, leukopenia, thrombocytopenia. Physical Exam Findings Malar rash sparing nasolabial folds. Discoid lesions (chronic cutaneous lupus). Oral ulcers (painless). Synovitis without erosions. Pericardial or pleural friction rubs. Lower extremity edema in nephritis. Making the Diagnosis Labs: ANA: sensitive, not specific. Anti–double-stranded DNA (anti-dsDNA): specific, correlates with disease activity (esp. nephritis). Anti-Smith antibody: highly specific, not prognostic. Anti-phospholipid antibodies: increase risk of thrombosis and pregnancy loss. Complement (C3, C4) may be low in active disease. Urinalysis / renal biopsy if nephritis suspected. Diagnosis is clinical + immunologic criteria (ACR/EULAR). Management General: sun protection, smoking cessation. Mild disease (skin, joint): NSAIDs, hydroxychloroquine. Moderate disease (serositis, cytopenias): corticosteroids ± immunosuppressants (azathioprine, methotrexate). Severe/life-threatening disease (nephritis, CNS, diffuse vasculitis): high-dose corticosteroids + immunosuppressants (cyclophosphamide, mycophenolate). Biologics: belimumab for refractory cases. Pregnancy: hydroxychloroquine safe; avoid methotrexate, cyclophosphamide. Monitor for complications: accelerated atherosclerosis, infection risk (due to immunosuppression). Question A 29-year-old woman presents with recurrent joint pain and swelling in her hands and knees for the past 6 months. She reports fatigue, low-grade fever, and a rash that appears across her cheeks after sun exposure. Exam shows tender, swollen MCP and PIP joints bilaterally, with no deformities. Laboratory studies reveal a positive ANA and low complement levels. Which of the following additional findings is most likely to be seen in this patient?
Shоulder Dislоcаtiоn Bаckground The glenohumerаl joint is the most commonly dislocated joint in the body due to its wide range of motion and relatively shallow glenoid cavity. Anterior dislocation is by far the most common (≈95%), usually from trauma with the arm abducted and externally rotated. Other types: posterior (associated with seizures, electrocution), inferior (rare, hyperabduction injury). Symptoms Sudden onset of shoulder pain and loss of function after trauma. Patient often holds the arm slightly abducted and externally rotated (anterior type). May report a popping sensation at the time of injury. Physical Exam Findings Anterior dislocation: flattening of the deltoid contour with a prominent acromion (“squared-off shoulder”), palpable humeral head anteriorly. Limited ROM due to pain. Assess for neurovascular compromise: axillary nerve injury (loss of sensation over lateral shoulder, weakness of deltoid). Posterior dislocation: arm held adducted and internally rotated; may be subtle and missed on AP films. Making the Diagnosis X-rays are required to confirm and to exclude fracture: AP and lateral (scapular “Y” view, axillary view). Important especially for posterior dislocations, which can be missed on AP alone. MRI/CT if recurrent or associated soft tissue injury suspected. Management Closed reduction is first-line (various techniques: traction-countertraction, external rotation, scapular manipulation). Post-reduction: confirm with X-ray and assess neurovascular status. Immobilization in sling and early rehab. Surgery may be indicated for recurrent dislocations, associated fractures, or soft tissue injuries. Recurrence risk is higher in younger patients and those in contact sports. QUESTION A 24-year-old man falls while playing basketball and lands on his outstretched arm externally rotated and abducted. He immediately develops severe right shoulder pain and refuses to move the arm. On exam, the arm is held slightly abducted and externally rotated. Active motion is limited due to pain. Which of the following additional findings is most likely present on physical examination?
Cаrpаl Tunnel Syndrоme (CTS) Bаckgrоund Caused by cоmpression of the median nerve as it passes through the carpal tunnel beneath the transverse carpal ligament. Risk factors: repetitive wrist/hand use, obesity, diabetes, hypothyroidism, pregnancy, rheumatoid arthritis. Most common compressive neuropathy of the upper extremity. Symptoms Numbness, tingling, burning, or pain in the median nerve distribution (thumb, index, middle, and radial half of the ring finger). Symptoms worse at night or with activities requiring wrist flexion (driving, typing). May report dropping objects or hand clumsiness. Physical Exam Findings Positive Phalen’s test: reproduction of symptoms with wrist flexion held for ~60 seconds. Positive Tinel’s sign: tingling in the median nerve distribution when tapping over the carpal tunnel. Thenar atrophy in advanced cases. Decreased grip strength. Making the Diagnosis Primarily clinical diagnosis. Nerve conduction studies / EMG used if diagnosis uncertain or before surgery. Imaging rarely required unless mass lesion suspected. Management Conservative: Wrist splinting in neutral position (especially at night). Activity modification. NSAIDs for symptom relief. Corticosteroid injections into carpal tunnel if persistent. Surgical: Carpal tunnel release (division of transverse carpal ligament) for severe, refractory, or progressive cases with weakness/atrophy. QuestionA 46-year-old woman who works as a data entry clerk presents with persistent numbness and tingling in her right hand involving the thumb, index, and middle fingers. She was diagnosed with carpal tunnel syndrome 3 months ago and has been using a neutral-position wrist splint at night without improvement. Exam shows decreased sensation in the median nerve distribution but no thenar atrophy. Which of the following is the most appropriate next step in management?
