Study Notes
Stress and Its Phases
- Stress can be triggered by various factors including anxiety, depression, disease, insomnia, infections, cardiovascular issues, and trauma.
- The body undergoes the General Adaptation Syndrome consisting of three phases: Alarm, Resistance, and Exhaustion.
- Alarm Phase: Sympathetic nervous system activation, release of catecholamines and cortisol (the stress hormone) from adrenal glands.
- Resistance Phase: Body adapts or alters; prolonged stress leads to exhaustion.
- Exhaustion Phase: Body becomes depleted and damaged, defenses are utilized.
Defense Mechanisms
- The body has three primary defense mechanisms against stress and injury:
- Physical Surface Barriers: Skin acts as the first line of defense.
- Inflammation: Triggered by tissue damage, it isolates and destroys invaders while facilitating cleanup.
- Immune Response: Engages the antigen/antibody response with lymphocyte production.
Inflammatory Response
- Inflammation initiates the healing process and protects the body by localizing injuries and disposing of foreign materials.
- Key mediators include mast cells, histamine (causes vasodilation and hypotension), and prostaglandins (stimulate pain receptors).
Vascular Responses
- Increases vascular permeability and causes vasodilation, leading to redness and heat, along with localized edema due to fluid leakage into tissues.
Cellular Response
- Neutrophils act as the primary responders, consuming microorganisms and debris. Chemotaxis facilitates their movement to the injury site.
Cardinal Signs of Inflammation
- Localized Signs: Heat, redness, swelling, pain, and loss of function.
- Systemic Signs: Fever, fatigue, weight loss, lethargy, increased leukocytes, and plasma proteins.
Inflammatory Exudates
- Four types of exudates:
- Serous/Sanguineous: Clear, protein-rich fluid.
- Fibrinous: Scab-like appearance indicating larger injury.
- Purulent: Contains dead/dying cells and pus-forming bacteria.
- Pyogenic: Pus-filled, can form abscesses or empyema.
Treatment of Inflammation
- Methods include ice packs to reduce blood flow, NSAIDs to decrease swelling, and antibiotics to block chemical mediators.
Phases of Healing
- Phase 1: Acute inflammation lasting 2-4 days with an early and late stage.
- Phase 2: Tissue formation, lasting 2-3 weeks with no chronic inflammation.
- Phase 3: Remodeling, may last up to a year post-injury.
Chronic Inflammation
- Ongoing inflammation with a prominence of monocytes, macrophages, and lymphocytes leading to granuloma and scarring formation.
Complications of Healing
- Possible issues include infection, ulceration, dehiscence, keloids, and adhesions.
Common Inflammatory Diseases
- Notable conditions include Rheumatoid Arthritis (RA), Gastritis, Inflammatory Bowel Disease (IBD), and Systemic Inflammatory Response Syndrome (SIRS) due to burns, sepsis, or trauma.
Rheumatoid Arthritis Pathophysiology
- Chronic inflammation of synovial membranes marked by hyperplasia.
- Etiology involves genetic factors, triggering events (like stress), and autoimmunity.
- Characterized by cycles of remission and exacerbation along with pannus formation, cartilage erosion, and ankylosis.
Clinical Manifestations of RA
- Symptoms range from mild to debilitating; affects joints symmetrically causing pain, stiffness, swelling, reduced mobility, redness, and heat.
RA Diagnostic Criteria
- No single definitive test; increased likelihood indicated by elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (IgG), and antinuclear antibodies (ANA).
RA Treatment
- Pharmacologic treatments include NSAIDs and COX-2 inhibitors (e.g., Celebrex).
- Non-pharmacologic interventions encompass rest/activity balance, physical therapy, splints, and potential surgery.
Inflammatory Lesions
- This term includes a variety of conditions such as wounds, ulcers, blisters, vesicles, pustules, or tumors related to inflammatory responses.

- Stress can be triggered by various factors including anxiety, depression, disease, insomnia, infections, cardiovascular issues, and trauma.
