|---|---|---|---|
| 1 | What is rheumatology primarily concerned with? | Rheumatology focuses on diseases involving joints, muscles, bones, and connective tissues, often characterized by inflammation and autoimmune processes. | Think of 'rheuma' as 'flow'โrelated to movement and connective tissues. |
| 2 | Define autoimmune disease. | An autoimmune disease occurs when the immune system mistakenly attacks the body's own tissues, leading to inflammation and tissue damage. | Autoimmunity = immune system's mistaken identity crisis. |
| 3 | What are common features of inflammatory rheumatic diseases? | Features include joint swelling, pain, stiffness (especially in the morning), fatigue, and sometimes systemic symptoms like fever or malaise. | Remember 'SPARM'โSwelling, Pain, stiffness, Malaise. |
| 4 | Name two hallmark autoantibodies associated with rheumatoid arthritis. | Rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies. | RF is classic but not specific; anti-CCP is more specific for RA. |
| 5 | What distinguishes autoimmune rheumatic diseases from infectious causes of joint inflammation? | Autoimmune diseases typically involve systemic immune dysregulation with autoantibodies and chronic inflammation, whereas infections are caused by pathogens producing acute or subacute inflammation. | Think 'auto' for self-driven, 'infectious' for pathogen-driven. |
| 6 | Explain the role of cytokines in rheumatic diseases. | Cytokines are signaling proteins that mediate inflammation and immune responses; overproduction or dysregulation contributes to disease pathogenesis. | Cytokines are like the 'messengers' amplifying inflammation. |
| 7 | What is synovitis? | Synovitis is inflammation of the synovial membrane lining joints, leading to swelling, pain, and stiffness. | Recall 'synovium' = joint lining. |
| 8 | Differentiate between osteoarthritis and inflammatory rheumatic diseases. | Osteoarthritis is a degenerative, non-inflammatory joint disease characterized by cartilage loss; inflammatory rheumatic diseases involve immune-mediated inflammation of synovial tissue. | Osteoarthritis = wear and tear; rheumatic = immune attack. |
| 9 | What is the significance of the HLA system in rheumatology? | Certain HLA gene variants (e.g., HLA-DR4) are associated with increased susceptibility to autoimmune rheumatic diseases like RA and psoriatic arthritis. | HLA = genetic 'handshake' influencing immune response. |
| 10 | Name a common systemic feature in connective tissue diseases. | Fatigue is a common systemic feature, often reflecting ongoing inflammation. | Fatigue = hallmark of systemic illness. |
| 11 | What does the term 'seronegative' mean in rheumatology? | It refers to rheumatic diseases that lack specific autoantibodies like RF or anti-CCP, e.g., psoriatic arthritis, ankylosing spondylitis. | Seronegative = no serum (autoantibodies) detected. |
| 12 | Describe the basic components of the immune system involved in rheumatic diseases. | Key components include T cells, B cells, autoantibodies, cytokines, and complement system, which collectively contribute to immune dysregulation and inflammation. | Think of immune components as an armyโsometimes misfiring. |
| 13 | Why are autoantibodies important in rheumatology? | Autoantibodies serve as diagnostic markers, help classify diseases, and may play a role in disease mechanisms. | Autoantibodies = disease fingerprints. |
| 14 | What is the significance of the term 'systemic' in systemic autoimmune diseases? | It indicates that the disease affects multiple organ systems beyond joints, such as skin, kidneys, lungs, and heart. | Systemic = all-encompassing. |
| 15 | Name an example of an inflammatory cytokine targeted by biologic therapies. | Tumor necrosis factor-alpha (TNF-ฮฑ) is a common target of biologic agents like infliximab and etanercept. | TNF-ฮฑ = a key inflammatory 'messenger'. |
| 16 | What role does complement activation play in rheumatic diseases? | Complement activation amplifies inflammation and tissue injury, playing a role in disease pathogenesis, especially in diseases like lupus. | Complement = immune system's 'amplifier.' |
| 17 | Define 'clinical remission' in rheumatology. | A state where there are no signs or symptoms of active disease, often confirmed by clinical assessment and lab tests. | Remission = disease 'quiet' or inactive. |
| 18 | What is the significance of the ANA test in rheumatology? | Anti-nuclear antibody (ANA) testing helps identify autoimmune diseases, especially systemic lupus erythematosus, but is not disease-specific. | ANA = broad autoantibody marker. |
| 19 | Explain the concept of 'joint stiffness' in rheumatic diseases. | Joint stiffness refers to the sensation of difficulty moving joints, often worse in the morning and improving with activity, characteristic of inflammatory conditions. | Stiffness is a hallmark of inflammation, not degeneration alone. |
| 20 | What is the typical age of onset for rheumatoid arthritis? | RA most commonly presents between the ages of 30 and 60 years, but can occur at any age. | Middle-aged adults are the usual demographic. |
