ABOUT CONTACT DERMATITIS• Beings as itching, redness, and swelling of the

skin.• May eventually start to blister.• Caused by exposure of the skin to chemicals.• Example: Poison Ivy• Can provoke allergic responses in sensitive

PSORIASIS Psoriasis causes cells to build up rapidly on

the surface of the skin, forming thick silvery scales and itchy, dry, red patches that are sometimes painful.

Experts believe that psoriasis occurs when the immune system overreacts, causing inflammation and flaking of skin.

Things that can cause these flare-ups include a cold and dry climate, infections, stress, and dry skin.

When psoriasis is moderate or severe, the skin gets inflamed with raised red areas topped with loose, silvery, scaling skin.

If psoriasis is severe, the skin becomes itchy and tender.

Most cases of psoriasis are mild, and treatment begins with skin care. Which includes keeping skin moist with lotion

BURNS• A BURN is tissue damage and cell death caused by intense heat, electricity, UV radiation,

or certain chemicals such as acid.

• There are 3 main classifications of burns: 1st, 2nd, and 3rd degree

- 1st Degree: Only epidermis is damaged. Area of burn becomes red. Ex: Sunburn

- 2nd Degree: Involves injury to the epidermis & the upper region of the dermis. Skin is red, painful, & blisters appear.

- 3rd Degree: Destroy entire thickness of skin. Burned areas appear blanched (gray-white) due to nerve endings being destroyed.

• Burns are considered critical if….

1. Over 25% of the body has 2nd degree burns

2. Over 10% of the body has 3rd degree burns

3. There are 3rd degree burns on the face, hands, or feet
