Explain the concept of inflammation
A protective immunologic response that defends against tissue
injury, infection, or allergy.
Inflammation at a vascular level (vasodilation)
- Prostaglandins and leukotrienes
- Bradykinins (pain production)
- Histamine and serotonin
- Platelet-activating factor
Inflammation at a vascular level (increased vascular permeability)
- COMPLEMENT PROTEINS
- Prostaglandins and leukotrienes
- Bradykinins
- Histamine and serotonin
- Platelet-activating factor
Inflammation at the cellular level
- MARGINATION and ADHESION
- Macrophages, neutrophils, B lymphocytes, dendritic cells
(responsible for fever)
Patho of acute inflammation
1. Injury to tissue
2. Vasodilation
3. Swelling and partial retraction
4. Increased vascular permeability
5. Walling off the surrounding tissue to prevent spread
,6. Margination and migration
7. Exudates fill space left by damaged tissue
8. Glucose and O2 move to support repair
9. Formation of endothelial cells
Manifestations of local inflammation
- Swelling
- Pain
- Heat
- Redness
- Loss of function
- Exudate
Manifestations of systemic inflammation
- Fever (dendritic cells)
- Leukocytosis
- Increased plasma proteins and WBC
- Malaise
- Fatigue
- Loss of appetite
- Generalized muscle aches
- Sepsis (worst case)
Chronic inflammation
- When inflammatory response lasts more than 5 days
- Healing process interrupted by reinjury, renewed inflammation,
and immune system activity
Manifestations of chronic inflammation
- Body aches/pains
- Frequent infections
- Diarrhea
- Dry eyes
- Loss of appetite - Muscle breakdown
- increase CRP and ESR
Consequences of excessive inflammatory response
- Local tissue damage due to compression
- Atherosclerosis
- CKD
- Development of chronic diseases
Risk factors for an impaired inflammatory response
, - Older adults (suppressed)
- Very young (suppressed or exaggerated)
- Uninsured individuals
- Compromised immune system
- Autoimmune disease and allergies
- Chronic diseases
- Obesity
- Environmental factors
- Metabolic syndrome
Primary prevention of inflammation
- Hand hygiene
- Keep wounds clean/covered
- Using designated safety equipment
- Awareness of food/water safety standards
Clinical Management: Collaborative Interventions
- Rest, Ice (24-48hrs), Compression, Elevation
- Immobilization devices
- Steriods
- NSAIDS
- Recombinant DNA and monoclonal antibodies
- Antipyretics
- Analgesics
- Antimicrobials
Patho of appendicitis
Blockage of the appendix lumen -> increased pressure -> swelling
causes more blockage -> thrombosis, ischemia, trapped bacteria ->
gangrene -> perforation
Initial appendicitis symptoms
- Dull periumbilical pain
- Anorexia
Symptoms of progressing appendicitis
- Sharp RLQ pain
- Tenderness at McBurney point
- RLQ rebound tenderness
- Rovsing sign (palpate LLQ)
- Low-grade fever
- Nausea
- Constipation
