Study Notes

Osteoarthritis (OA)

Most prevalent chronic joint condition; often referred to as "overuse arthritis."
Significant contributor to global disability; approximately 5 million Canadians are diagnosed.
Prevalence expected to rise due to an aging population.
Risk factors include obesity, decreased estrogen post-menopause, ACL injuries, genetics, certain occupations, and regular moderate exercise.

OA Etiology

Medications: Some can stimulate collagen-digesting enzymes, harming cartilage.
Joint instability & trauma: Results from uneven stress and dislocations or fractures, respectively, leading to cartilage deterioration.
Neurological disorders: May result in abnormal movements causing cartilage damage.
Mechanical stress: Repetitive physical activities contribute to joint wear.

OA Pathophysiology

Characterized by gradual loss of articular cartilage and formation of bone spurs (osteophytes).
Roughening of cartilage disrupts smooth joint movement; enzymatic damage accelerates cartilage disintegration.
Collapsed joint space observable via x-ray; secondary inflammation may occur.
Articular cartilage transitions from smooth and glistening to dull and granular, losing elasticity.

Parkinson’s Disease (PD)

Primarily affects older adults; risk factors include male sex, genetics, head trauma, and certain occupations.
Clinical manifestations include:
- Resting tremors that cease with movement or sleep.
- Bradykinesia: Slowness of movement.
- Muscle rigidity and postural instability.
- Difficulty with complex movement tasks, such as standing or initiating motion.

PD Complications

Disease progression may lead to severe dementia, akinesia, and depression.
Dysphagia increases risk of aspiration pneumonia and UTIs, alongside skin breakdown due to weakness.

PD Diagnosis & Management

Diagnosis through thorough clinical examination; absence of specific tests.
Key symptoms include bradykinesia, rigidity, and tremors.
Management focuses on symptom relief through dopamine replacement therapies (e.g., Levodopa), surgical interventions, and occupational therapy.

Spina Bifida Overview

Neural tube defect resulting from failure to close during embryonic development.
Severity varies across types: Occulta (mildest), Meningocele, and Myelomeningocele (most severe).
Maternal folate supplementation recommended to prevent occurrence.

Spina Bifida Clinical Manifestations

Occulta: Often asymptomatic; may present with skin findings (e.g., tuft of hair).
Meningocele: Potential bladder and bowel dysfunction; usually correctable with surgery.
Myelomeningocele: Exposes nerves and meninges; higher risk for infections and significant spinal cord damage.

Diagnosis and Assessment of Spina Bifida

Myelomeningocele often diagnosed prenatally via serum alpha-fetoprotein screening, with confirmation from amniocentesis.
Assessment considers spinal cord involvement, visible spinal defects, and potential hydrocephalus.

Spina Bifida Nursing Interventions

Prevent infection and injury to spinal defects using correct positioning.
Conduct thorough skin care and urological monitoring.
Educate families about condition management and potential complications like hydrocephalus and latex allergies.

Osteoarthritis (OA)

Most common chronic joint condition, referred to as “overuse arthritis”.
Significant cause of disability globally; affects approximately 5 million Canadians.
Predicted increase in prevalence due to an aging population.
Involves degeneration of articular cartilage leading to joint pain and stiffness.
Commonly affects weight-bearing joints (knees, hips) and hands.
Early symptoms include inflammation and pain; later symptoms show joint surfaces rubbing together.

OA Etiology and Risk Factors

Factors leading to OA include medication effects, chronic inflammation, joint instability, mechanical stress, and hematological disorders.
Risk factors include genetic predisposition, obesity, and age.
No specific lab tests required for diagnosis, but imaging reveals joint space narrowing and osteophytes.

OA Clinical Manifestations

Symptoms include morning stiffness worsening throughout the day, swelling without redness or warmth, and possible crepitus (grating sensation).

Diagnosis and Grading

Kellgren & Lawrence grading system assesses OA severity from 0 (normal) to 4 (severe).

OA Management

No cure; management focuses on pain relief and reducing inflammation.
Pharmacological options include acetaminophen, NSAIDs, and Celebrex.
Non-pharmacological interventions include weight management, physiotherapy, and possible referral for joint replacement.

Parkinson's Disease (PD)

Progressive neurodegenerative disorder affecting the central nervous system, primarily the basal ganglia.
Characterized by bradykinesia, rigidity, resting tremor, and impaired gait.
Second most common neurodegenerative disease; common onset post-65 years of age.
Unclear etiology with no established cure.

PD Pathophysiology and Risk Factors

Caused by degeneration of dopamine-producing neurons in the Substantia Nigra.
Risk factors include age, male sex, genetic predispositions, head trauma, and certain occupations.

PD Clinical Manifestations

Initial symptoms often include resting tremor, slowness of movement (bradykinesia), and muscle rigidity.
Progression results in reduced arm swing, stooped posture, propulsive gait, and complex movement difficulties.
Advanced symptoms involve lower speech volume, difficulty swallowing, drooling, and a mask-like expression.

PD Complications

Increased risk of dementia, akinesia, depression, dysphagia, and other secondary health issues.
Significant challenges with motor function leading to potential aspiration pneumonia and skin breakdown.

PD Diagnosis

Diagnosed based on clinical examination; no definitive tests.
Symptoms must indicate bradykinesia, rigidity, and resting tremor (TRAP).
Positive response to dopaminergic medications can help confirm diagnosis.

PD Management

Levodopa (l-dopa) is a primary treatment for motor impairment.
Other options include selegiline, pramipexole, anticholinergics, and surgical interventions like deep brain stimulation.
Management remains symptomatic, focusing on improving quality of life.

Spina Bifida

Neural tube defect resulting from the failure of spinal cord closure during embryonic development.
Types include Spina Bifida Occulta (least severe), Meningocele, and Myelomeningocele (most severe).
Preventable with maternal folate supplementation pre-conception.

Spina Bifida Clinical Manifestations

Symptoms range from skin indicators (e.g., tuft of hair, dimples) in occulta, to bladder/bowel control issues and paralysis in myelomeningocele.
Other concerns include orthopedic abnormalities, pressure sores, and lack of sensation.

Diagnosis and Assessment of Spina Bifida

Prenatal diagnosis often involves measuring maternal serum alpha-fetoprotein.
Physical assessment may reveal flaccid paralysis, hydrocephalus, and joint deformities.

Spina Bifida Treatment

Surgical interventions may be necessary both prenatally and postnatally to minimize risks of complications.
Ongoing support typically required for mobility and bladder/bowel function.

Nursing Interventions for Spina Bifida

Focus on preventing infection and injury to spinal defects.
Implementing correct positioning and good skin care to prevent complications.
Continuous medical supervision and education for parents about the condition and care needs.
