Cyndi - Week 16 - Exam 7 Flashcards
what is scleroderma?
- autoimmune affects connective tissue - inflammation, sclerosis, and fibrosis
what is arthritis?
progressive deterioration of synovial joints
- osteoarthritis
- rheumatoid arthritis
- gout
what are the characteristics of osteoarthritis?
Occurs in synovial joints:
• Not normal aging process
• Stress on joints – excessive load or damaged joint
• Excessive pressure breaks down cartilage
• Inflammatory response further degrades cartilage
• Chondrocytes (cartilage producing cells) repair
damage, but over time there is erosion of
cartilage, and bone beneath becomes exposed
• Osteocytes deposited – bony spurs
• Heberden’s and Bouchard’s nodes
• Usually asymmetrical
what are the risk factors of OA?
- Age
- Gender
- Obesity
- Sedentary lifestyle
- Occupational
what are the causes of OA?
- Trauma
- Mechanical stress
- Inflammation
- Joint instability
- Neurological disorders
- Skeletal deformities
- Hematologic/endocrine
- Medications
what are the clinical manifestations of OA?
No systemic involvement – symptoms are joint‐specific
• Pain – from bone against bone, bone spurs, nerve impingement
• Especially after exercise or weight bearing, relieved with rest
• Sleep disturbances from pain
• Crepitation
• Asymmetrical
• Fingers, hip, knee, spine, and cervical joints most common
• Bouchards and/or Heberden’s nodes
• Movement increases pain
• Joint stiffness, decreased ROM in joint
what are the labs used for OA?
**Biochemical markers • Serum osteocalcin • Hyaluronic acid levels (component of syn. fluid) **Rule out rheumatoid arthritis • Rheumatic Factor ‐ negative
what are the radiology used for OA?
• X‐ray ‐– confirmation and staging
• Degree of disease seen may not correspond to degree of symptoms
Bone scan, CT, MRI – for diagnosis
**Synovial Fluid Analysis ‐ differentiate OA from RA
TEACHING POINT: what are the goals for OA tx?
Goals –manage pain, prevent disability, improve joint use
what are the different methods of pain control for OA?
- Salicylates
- NSAIDs
- Hyaluronic acid
- Glucosamine, chondroitin, MSM
- Topical
- Cortisone
- Heat and ice
- Alternative therapies
what is the pt education for OA?
- Balance of rest and joint protection
- Nutrition
- Weight reduction
is surgery possible for OA?
yes!
- replacement of degenerative joint and arthroscopy
what are the complications of OA?
usually just local joint breakdown causing
decreased mobility
what is rheumatoid arthritis?
Chronic autoimmune, inflammatory disorder that affects the joints and may have systemic affects
what are the characteristics of RA?
- Inflamed connective tissue in synovial joints
- Extra‐articular (systemic) symptoms may occur
- Process of destruction
- Exacerbations and remissions
what are the risk factors for RA?
- Any age
- Women 2‐3x more
- Cause unknown
- Genetic – 50% of risk?
- Hormones?
- Infection?
what are the 4 stages of RA?
Stage 1 - mild; early, beginning, not ID’d on XRay
Stage 2 - moderate, joint stiffness, swelling
Stage 3 - severe; subluxation (stretching), risk for infection d/t bump
Stage 4 - terminal; bony growth, results in fusion of joint, immobility
what are the RA joint specific symptoms? TP*
• Symmetrical
• Inactivity causes stiffness
• Pain lessens with movement (but
worsens with overuse)
• Pain, stiffness, limited motion, heat, swelling
• Frequently small joints, but can include large joints and
cervical spine
• Severe results in distortion, subluxation,
dislocation
• Sometimes have “swan neck” deformity TP
what are the RA non-joint specific symptoms?
Fatigue, anorexia, wt. loss, stiffness – insidious onset
• Rheumatoid nodules
• Cardiopulmonary effects (pericarditis → late stages)
• Sjogren’s syndrome (↓ lacrimal/saliva secretion → dry)
• Felty syndrome (severe nodules → splenacromegy → leukopenia)
• Cataracts
• Depression
what are the complications of RA?
- Increased deformity, infection/sore from nodules
- Dec ability to perform ADLs
- Visual changes/loss
- Cardiovascular disease, vasculitis
- Pulmonary changes – Pulmonary HTN, pleural effusion
