Study Notes
Rheumatology
- Study of rheumatic diseases and musculoskeletal disorders
- Includes autoimmune diseases, connective tissue disease, and more
Musculoskeletal System
- The skeleton proper (bones & joints)
- Skeletal muscles
- Tendons
- Ligaments
Inflammatory vs Non-inflammatory
- Inflammatory characteristics:
- Erythema
- Warmth
- Pain
- Swelling
- Prolonged stiffness
- Systemic symptoms
- Laboratory abnormalities
- Non-inflammatory characteristics:
- Mechanical pain (worse with activity)
- Degenerative disorder /metabolic dis /endocrine dis
- Improves with rest
- Stiffness after brief periods of rest (not prolonged)
- Absence of systemic signs
Differential Diagnosis for Joint Pattern
- Monoarticular (single joint):
- Trauma
- Hemarthrosis
- Spondyloarthropathy
- Septic arthritis
- Crystal-induced
- Oligoarticular (2-4 joints):
- Spondyloarthropathy
- Crystal-induced
- Infection-related
- Polyarticular (5 or more joints):
- RA
- SLE
- Crystal-induced
- Infectious
Rheumatologic Diseases
- Osteoarthritis
- Rheumatoid Arthritis
- Seronegative spondyloarthropathy
- Crystal-induced arthritis
- Systemic lupus erythematosus
- Vasculitis
- Scleroderma
- Inflammatory Myopathy
Duration of Disease
- Acute: less than 6 weeks
- Subacute: 6 weeks to 6 months
- Chronic: more than 6 months
Clinical Features
- Pain
- Swelling
- Power loss
- Tenderness
- Extra-articular symptoms (e.g. rash, cough, fever, ulcers)
- Low platelet count and anemia
Differential Diagnoses
- Fracture
- Sprain
- Dislocation or subluxation
- Joint or muscle inflammation
- Age-specific abnormality
- Systemic illness (e.g. neuropathy, myopathy, connective tissue disease)
Additional Factors
- Type of joint involved
- Muscle power affected
- Other systems involved (e.g. lung, eye, CNS)
