Skin Disorders/Musculoskeletal Disorders
A. Skin Disorders
(1) Compare the mechanisms and possible causes of allergic and irritant contact dermatitis.
a. Allergic contact dermatitis - Allergic contact dermatitis is a hypersensitive reaction that follows absorption of antigen applied to the skin and recruitment of previously sensitized, antigen-specific T lymphocytes into the skin. The antigens are
usually low-molecular-weight substances that readily penetrate the stratum corneum. Most contact allergens are weak and require repeated exposure before sensitization occurs. Strong antigens, such as poison ivy, require only two exposures for sensitization.
b. Irritant contact dermatitis - a nonimmunologic local inflammatory reaction characterized by erythema, edema, or corrosion following single or repeated application of a chemical substance to an identical cutaneous site.
(2) Prepare a list of contagious skin disorders.
- Impetigo
- Scabies
- Lice
- Herpes Simplex
(3) Suggest a preventative measure that could reduce the risk of skin cancer.
- Avoiding both direct sunlight, and sunlight reflected from water, sand and snow.
- Shielding the skin with tightly knit clothing, long-sleeved garments andHats with broad brims.
- Using sunscreen.
(4) Explain why allergic responses tend to recur.
