  2. Agenda 12/10 • Research & Report Presentations • Medical Terminology • Quiz Tuesday

  3. Agenda 12/11 • Research & Report Presentations • Medical Terminology Quiz • Chapter 4 Quiz 2 Friday 12/14 • Chapter 4 TEST Wednesday 12/19

  4. Warm-up 12/12 • Using your knowledge about the Integumentary system and skin structure, how would YOU classify burns into 3 different classes? (First, Second & Third Degree) • As a table group, write a description for each burn class. • What layers involved? • What kind of damage?

  5. Burn Classification

  6. Agenda 12/12 • Finish Research & Report Presentations (LAST CHANCE) • Notes: Homeostatic Imbalances of the Skin • What are the differences between 1st , 2nd, and 3rd degree burns? • What is the importance of the “Rule of Nines”? • What are the basic characteristics of basal cell carcinoma, squamous cell carcinoma and malignant melanoma? • Homework p.16 in packet • Chapter 4 Quiz 2 Friday 12/14 • Chapter 4 TEST Wednesday 12/19

  7. C. Skin Homeostatic Imbalances • Infections • _________________________ • Caused by fungal infection • ___________________ • Caused by bacterial infection • __________ • Caused by virus Boils and Carbuncles Athlete’s Foot (tineapedis) Cold sores

  8. Athletes Foot • Fungal Infection

  9. Boils • Inflammation of hair follicles/sebaceous glands—Staph Infection (Carbuncles)

  10. Cold Sore/Canker Sore Canker Sores: Caused by break in the mucous membrane Cold Sores: Active Herpes Infection

  11. C. Skin Homeostatic Imbalances • Infections and allergies • _________________ • Exposures cause allergic reaction • _________ • Caused by bacterial infection • _________ • Cause is unknown • Triggered by trauma, infection, stress Contact dermatitis Impetigo Psoriasis

  12. C. Skin Homeostatic Imbalances Figure 4.10

  13. Dermititis • Poison Oak: Allergic Response to Chemical Defense of Plant

  14. Dermititis • Poison Ivy: Allergic Response to Chemical Defense of Plant

  15. Impetigo • Staph Infection (Blister Form)

  16. Psoriasis • Scaled epidermis, increased rates of mitosis, highly keratinized.

  17. C. Skin Homeostatic Imbalances • Burns • Tissue damage and cell death caused by ________________________________ • Associated dangers • ____________ • ____________________ • ________________ Heat, electricity, UV radiation, or chemicals Dehydration Electrolyte imbalance Circulatory shock

  18. 3. Burns Rule of Nines • ____________ - Way to determine the extent of burns • Body is divided into 11 areas for quick estimation • Each area represents about 9% of total body surface area

  19. Rule of Nines

  20. 3. Burns • Severity of Burns • First-degree burns • _________________________ • _____________________ • Second-degree burns • __________________________________ • _____________________ • Third-degree burns • _____________________ • _______________________ Only epidermis is damaged Skin is red and swollen Epidermis and upper dermis are damaged Skin is red with blisters Destroys entire skin layer Burn is gray-white or black

  21. Severity of Burns What Degree? Third Degree First Degree Second Degree

  22. 3. Burns • Critical Burns Burns are considered critical if • ________ of body has second-degree burns • ________ of the body has third-degree burns • There are third-degree burns of the face, hands, or feet Over 25% Over 10%

  23. Warm-up 12/13 • Fill in the Following chart as best you can.

  24. Agenda 12/13 • Notes: Homeostatic Imbalances of the Skin • What is the importance of the “Rule of Nines”? • What are the differences between 1st , 2nd, and 3rd degree burns? • What are the basic characteristics of basal cell carcinoma, squamous cell carcinoma and malignant melanoma? • Homework p.16 in packet • Chapter 4 Quiz 2 Friday 12/14 • Chapter 4 TEST Wednesday 12/19

  25. D. Skin Cancer • abnormal cell mass, the most common type of cancer • Classified two ways • _______ • Does not spread (encapsulated) • __________ • Metastasized (moves) to other parts of the body Benign Malignant

  26. D. Skin Cancer • Skin Cancer Types • ___________________ • Least malignant • Most common type • Arises from stratum basale Basal cell carcinoma

  27. Skin Cancer Types Figure 4.12a

  28. BASAL CELL CARCINOMA

  29. BASAL CELL CARCINOMA

  30. 2. Skin Cancer Types Squamous cell carcinoma • ______________________ • Metastasizes to lymph nodes if not removed • Early removal allows a good chance of cure • Believed to be sun-induced • Arises from stratum spinosum

  31. Skin Cancer Types Figure 4.12b

  32. Squamous Cell Carcinoma

  33. Squamous Cell Carcinoma

  34. 2. Skin Cancer Types • ___________________ • Most deadly of skin cancers • Cancer of melanocytes • Metastasizes rapidly to lymph and blood vessels • Detection uses ABCD rule Malignant melanoma

  35. Skin Cancer Types Figure 4.12c

  36. 3. ABCD Rule • A = Asymmetry • Two sides of pigmented mole do not match • B = Border irregularity • Borders of mole are not smooth • C = Color • Different colors in pigmented area • D = Diameter • Spot is larger then 6 mm in diameter
