Study Notes
Skin Cancer Terminology
- Benign: Non-cancerous growth that does not spread to other parts of the body.
- Malignant: Presence of cancerous cells capable of metastasizing to other sites.
- Biopsy: Procedure for removing tissue or cell samples for laboratory testing.
- Metastasis: Cancer that has spread from its original location to another body part.
- Histology: Medical branch studying cell structure and function.
Types of Skin Cancer
- Non-melanoma: Includes basal cell carcinoma and squamous cell carcinoma.
-
Melanoma: A more aggressive type of skin cancer characterized by the ABCDE rule:
- Asymmetry: One half differs from the other.
- Border irregular: Edges are not smooth.
- Color variations: Different colors within the mole.
- Diameter >5mm: Larger than a pencil eraser.
- Evolution: Changes in size, shape, or color.
Skin Cancer Treatment
- Surgery: Techniques include curettage and cryosurgery.
- Radiation therapy: Targets cancer cells with radiation.
- Chemotherapy: Uses drugs to kill or slow the growth of cancer cells.
Skin Cancer Risk Factors and Prevention
- UV Rays: Major risk factor for skin cancer.
-
Prevention strategies:
- Limit sun exposure.
- Use sunscreen.
- Wear protective clothing, like hats and long sleeves.
Burn Terminology
- Contractures: Permanent shortening of muscles leading to limited movement.
- Debridement: Removal of damaged tissue from wounds.
- Eschar: Dead tissue that is dry and dark in appearance.
- Hypertrophic scar: Thick, raised skin that remains within the boundaries of the wound.
- Keloid: Firm, smooth scar growth extending beyond the original wound.
Types of Burns
- Categories: Thermal, chemical, electrical, and radiation/solar burns.
-
Depth classifications:
- Superficial: Affects only the outer layer of skin.
- Partial thickness: Involves deeper layers but not all the way through.
- Full thickness: Extends through all skin layers, potentially affecting underlying tissues.
First Responder Actions for Burns
- Remove the source of the burn.
- Cool the burn with cool water.
- Remove clothing and jewelry from the burn area.
- Assess airway, breathing, and circulation.
Pathophysiology of Burns
- Major burns compromise the skin's normal physiological functions:
- Water loss prevention.
- Protection against bacterial entry.
- Maintenance of body temperature.
- Burn injuries can lead to hypovolemic shock (burn shock):
- Increased blood viscosity due to serum osmolality changes.
- Higher risk of blood clots.
Collaborative Care for Burn Patients
- Pain management: Administer morphine as an analgesic.
- Infection risk: Potential increase in infection due to fluid shifts causing blood viscosity changes.
- Burn contractures: Implement interventions such as splinting, range of motion exercises, and promoting patient independence.
