Study Notes

Inflammatory Disorders and Surgical Interventions

Rheumatoid Arthritis (RA): A chronic, systemic autoimmune disease causing inflammation of synovial membranes (synovitis) in diarthrodial joints.
Etiology:
- Severe and crippling form of arthritis.
- Affects approximately 1.5 million people.
- Likely autoimmune with genetic predisposition.
- Significantly more common in women (nearly three times more than men).
- Most prevalent in women aged 30-60.
- Smoking increases RA risk in men and women with genetic predisposition.
- Bacterial and viral diseases are additional risk factors.
Pathophysiology:
- Chronic synovitis in diarthrodial joints.
- Periods of remission and exacerbation.
- Immune system malfunction, leading to ongoing immune response.
Clinical Manifestations:
- Chronic inflammation damages joints and surrounding tissue, leading to deformity and loss of function.
- Potential stressful events as precipitating factors (infection, stress, exertion, childbirth, surgery, emotional upset).
- Remission: inflammation, pain, stiffness, edema subside; tissue damage progression halts.
Assessment (Subjective):
- Joint pain, tenderness, swelling, or stiffness for 6 weeks or more.
- More than one joint affected.
- Morning stiffness lasting 30 minutes or more.
- Small joints (wrists, hands, feet) affected.
- Symmetrical joint involvement.
Assessment (Objective):
- Joint edema.
- Joint tenderness.
- Subcutaneous nodules.
- Limited range of motion (morning stiffness).
- Symmetrical joint involvement.
- Fever.
Diagnostic Tests:
- No single definitive test.
- Diagnosis based on history, physical examination, and four classic symptoms (morning stiffness, joint pain, muscle weakness, fatigue).
- Radiographic studies show cartilage loss and subchondral bone changes.
- Arthrocentesis reveals cloudy, milky, or dark yellow synovial fluid with inflammatory cells.
- Anti-CCP antibody test frequently positive, can identify RA before symptoms. Other blood tests (C-reactive protein, CBC, ESR, ANA) may be elevated.
Medical Management:
- Aggressive treatment early on.
- Disease-modifying anti-inflammatory drugs (DMARDs) to control disease activity.
- Pain relief.
- Reduce symptoms quickly (e.g., methotrexate).
- NSAIDs may be used to further reduce inflammation.
- Promote long-term joint function with physical therapy & splints.
- Slow joint damage progression with ADL modification, exercise, weight management.
Surgical Management:
- Arthroplasty (joint replacement) can restore lost function and relieve pain.
Nursing Management:
- Educate patients about the disease, health maintenance, pain relief, stress reduction, and inflammation management.
- Medication regimen instruction, including therapeutic and adverse effects.
- Heat/cold application (safety instructions).
- Collaboration with therapists for exercise, ADL modifications, and splints to maintain joint alignment and movement. Encourage nutrition and hydration.
Prognosis:
- Variable, characterized by remissions and exacerbations.
- Stages exist, from early effects to terminal stage, marked by severe deformities, muscle atrophy, soft tissue lesions, bone-cartilage destruction, and ankylosis.

Other Inflammatory Joint Disorders

Ankylosing Spondylitis:
- Chronic connective tissue disorder of spine and surrounding joints.
- More common in men; women have milder forms.
- Etiology unknown—possible altered immune response.
- Strong familial tendency in some.
- Pathophysiology: Immobility/ankylosing of joints extending from the hip upwards.
- Respiratory compromise with kyphosis (hunchback).
- Cardiovascular involvement (enlarged heart, pericarditis).
- Vision loss from glaucoma, pupil damage, iridocyclitis.
- Pulmonary fibrosis.
- GI involvement (inflammatory bowel disease).
- Symptoms: Back pain, stiffness, sciatica (lasting a few days repeatedly), weight loss, abdominal distension, peripheral joint edema.
- Diagnosis: Elevated ESR/CRP, elevated alkaline phosphatase/creatinine phosphokinase. HLA-B27 present in 90% of patients. X-rays/CT scans show joint fusion.
- Medical Management: NSAIDs, corticosteroids, biologic response modifiers (Enbrel, Remicade, Humira). Firm mattress, exercise, back brace.
- Nursing Management: Spine alignment maintenance. Supportive furniture and positioning. Breathing & positional exercises.
Osteoarthritis (Degenerative Joint Disease):
- Most common arthritis type; "wear-and-tear" disease, primarily in weight-bearing joints.
- Non-systemic, non-inflammatory; progressive bone/joint degeneration.
- Almost inevitable with age; most adults have joint changes by age 70.
- Primary (unknown cause) and secondary (trauma, infection, prior fracture, RA, obesity, professional athletes, etc.) forms.
- Risk factors: Increased age, prior joint injury, obesity, congenital/developmental disorders, hereditary, and bone diseases.
- Symptoms: Joint stiffness, pain, enlargement, limited movement, Herberden's nodes (distal interphalangeal), Bouchard's nodes (proximal interphalangeal joints), crepitus, progressive ROM limitations.
- Diagnosis: No specific test. Radiography, arthroscopy, synovial fluid exam, bone scans.
- Medical Management (Non-pharmacological): Exercise, physical therapy, heat, relaxation techniques.
- Medical Management (Pharmacological): NSAIDs (initially starting with OTC or acetaminophen), steroids (for immediate pain relief), acetaminophen, other analgesics.
- Surgical Management: Reconstructive surgery for severely compromised mobility and quality of life (most common: hip and knee replacements). Materials: metal & high-density polyethylene.
- Post-operative complications: Hemorrhage, subluxation/dislocation, infection, thromboembolism, vascular necrosis.
- Nursing Management: Education on medications, activity modification, weight management, referrals, preoperative/postoperative assessments (e.g., maintain moderate activity appropriately), and neurovascular assessment.
Gout:
- Metabolic disease; uric acid accumulation in blood, acute inflammatory condition, ineffective purine metabolism.
- 8 times more common in men; usually middle-aged men.
- 85% of gout cases have genetic tendency.
- Types: Primary (genetic, severe dieting, excessive purine intake), secondary (medications, other diseases), idiopathic (unknown origin).
- Symptoms: Sudden onset pain, tenderness in one joint (first metatarsophalangeal), swelling/redness, hypersensitivity, potential fever, Tophi (urate deposits).
- Diagnosis: Urate crystals in synovial fluid. Radiographs might reveal urate deposits. Elevated serum uric acid levels. 24-hr urine specimen showing high uric acid.
- Medical Management: Uricosuric drugs to increase excretion, decreased purine intake, NSAIDs, colchicine for acute attacks (oral/IV).
- Nursing Management: Bed cradle to protect affected joint, hourly colchicine administration instructions, monitoring for GI symptoms, encourage high fluid intake, long-term drug/diet explanation.
Osteoporosis:
- Disorder of deficient bone density interfering with mechanical support.
- Impacts ~25% of women > 65.
- Types: Postmenopausal (estrogen deficiency), senile (ages 70-85, more in women).
- Risk factors: Small bone structure, white/Asian women, lack of exercise, smoking, alcohol, diseases (hyperthyroidism, COPD, cancer, IBD, alcoholism, vitamin D deficiency), steroid use, anticonvulsants.
- Symptoms: Initially asymptomatic, first symptom is often vertebral fracture. Height loss, stooped posture.
- Assessment: Pain, dowager hump, posture issues, loss of height over time.
- Diagnostics: Blood tests (CBC, calcium, phosphorus, ALP, kidney/liver/thyroid function), BMD test (DEXA; spine/hip assessment).
- Medical Management: Goal is bone density increase & loss retardation. Calcium supplements (1200-2000 mg/day), vitamin D (800 IU/day), weight-bearing exercise, alcohol restriction.
- Medications: Bisphosphonates (Alendronate, Zolendronic acid), calcitonin (salmon), estrogen receptor modulators, parathyroid hormone. Medication administration instructions to minimize negative side effects.
- Surgical Management: Vertebroplasty/kyphoplasty for vertebral compression fractures.
- Nursing Interventions: Diet rich in calcium (dairy, fortified foods), Vitamin D, limit caffeine/protein intake, promote safety, prevent falls, exercise.
Osteomyelitis:
- Bone marrow/bone infection (from trauma, surgery, blood-borne bacteria).
- Causing agents vary (Streptococcus viridans, etc.).
- Pathophysiology:Bacteria invade, bone degenerates; chronic osteomyelitis—weak bone, predisposition to fractures.
- Granulation tissue replaces necrotic tissue.
- Symptoms: Severe, persistent bone pain/tenderness, muscle spasms, limited joint mobility. Potential for chronic recurrent infections.
- Assessment: Complete history, vital signs, wound appearance (drainage), edema.
- Diagnostic Tests: Complete history, CT/MRI, lab values (CBC, ESR, CRP, needle aspiration), cultures.
- Medical Management: Wound care, prolonged/aggressive antibiotic therapy, necrotic tissue debridement, surgery to remove sequestra (dead bone).
- Nursing Considerations: Gentle extremity movement, positioning, wound care, high-calorie/protein diet, teaching on infection signs.
Fibromyalgia Syndrome (FMS):
