Exam 1 --Pt3 Joints --System Pathology Flashcards
What is arthritis? What sex is it more common in?
not a single disease or pathology, but a term to describe joint pain or joint pathology
- major source of morbidity in US
- MC in females
What are different forms for arthritis, in general?
- degenerative arthritis
- immune-mediated
- metabolic disorders affect joint
- infectious
- tumors involving joint
What is degenerative changes to articular cartilage of synovial joints that does not necessarily involve inflammation?
Osteoarthritis (OA, or degenerative joint disease, or DJD)
T/F. Osteoarthritis involves inflammation.
False. Does NOT necessarily involve inflammation, but MAY trigger it in advanced stages
What is the most common disease affecting the joints? What increases your risk of getting it?
osteoarthritis
- increase in age
What joint is characteristically involved with osteoarthritis?
DIP joints in hand
What is secondary osteoarthritis and what is usually the cause for developing it?
develop after injury/trauma, inf., or skeletal deformity Causes: - ACL, meniscus tears - obese - dislocate joint - joint inf. - congenital skeletal deform.
What age group does osteoarthritis affect?
Dx ~ age 50
Dx in ~1/2 of inds over 70
How does osteoarthritis develop? fast/slow?
it and the pain will develop insidiously (gradually)
T/F. Osteoarthritis usually manifests eventually with bony ankylosis.
FALSE! no ankylosis occurs
What type of arthritis does one wake with pain, but then after about 30mins of morning activities it decrease intensity?
osteoarthritis
What type of arthritis commonly involves multiple joints, such as knee, hip, shoulder, DIP joints of hand, and L or C spine?
osteoarthritis
Describe the development of osteoarthritis, from what it begins like and so on.
Begins with subtle softening of articular cartilage
- Bony Eburnation (art. bone erodes and subchondral bone becomes sclerotic
- Subchondral Cyst in bone due to synovial fluid entry
- Joint mice (free fragments of Fx subchondral bone)
What type of arthritis will manifest with osteophytes (bone spurs)? What are they called if on DIP joints?
osteoarthritis
Heberden nodes
What are Heberden nodes characteristic of? What are they?
osteoarthritis
- osteophytes on bone margins of DIP joints
What is a multisystem autoimmune disorder that causes chronic inflammation, primarily w/in small joints of hands, feet, wrists, ankles, and upper C spine?
Rheumatoid arthritis
Besides the small joints that Rheumatoid arthritis effects, what extraarticular areas does it effect?
CT of:
- skin
- heart
- blood vessels
- lungs
How many people are affected by rheumatoid arthritis? What sex? When is it Dx?
1% all US adults
3x MC in females
adulthood
What is the primary inflammatory cell found in tissues affected by RA?
CD4+ T cells
What about RA do chiropractors need to be aware of?
30% have atlanto-axial instability
What is present in about 80% of all patients with RA?
rheumatoid factor (RF)—IgM antibodies against ind’s own tissues
What type of arthritis that has chronic inflammation is likely to cause fibrous ankylosis and then lead to bony ankylosis?
Rheumatoid arthritis
What is condition “pannus” characteristic of? What is it?
Rheumatoid arthritis
- it is identical to granulation tissue found beneath skin wounds, except this forms in joints (foundation for fibrotic changes ass. with RA)
What type of arthritis comes on insidiously, is worse in the mornings and may not relieve with activity?
Rheumatoid arthritis
What joint is most likely to be involved in RA? What characteristic feature does it result in?
MCP joints
ulnar deviation of phalanges, symmetrically
What is “swam-neck deformity” and “boutonniere deformity” characteristic of?
Rheumatoid arthritis
- describing the ulnar deviation of the phalanges
What may develop within the subcutaneous tissues of inds. with RA? What area of skin are they MC formed?
Rheumatoid nodules
- forearm, elbows, occiput, and lumbosacral region
- rare in lungs
What condition involves having RA, neutropenia, and spenomegally?
Felty Syndrome
- recurrent infs, too few neutrophils
What age group and sex does Felty Syndrome MC affect?
elderly (50-70)
females
What condition involves a combination of RA and pneumoconiosis? (What is pneumoconiosis?)
Caplan syndrome
an occupational lung disease ass. with inhalation of particulate matter
What is Juvenile Rheumatoid Arthritis?
(JRA, or juvenile idiopathic arthritis-JIA)
- heterogenous group of disorders of unknown cause
- has diagnostic criteria
