Atopic Dermatitis
Atopic dermatitis (AD) is a chronic skin disorder that often develops in people who have asthma, hay fever, and other allergies. It causes an itchy, red, raised rash that may weep or ooze clear fluid. The rash may develop as tiny blisters, which break and crust over. The blisters are prone to infection, especially if scratching is not controlled.
In children, AD appears most often on the face, scalp, buttocks, thighs, and torso. AD is often worse during infancy. It improves in many children by age 5 or 6.
In adults, it usually appears on the neck and in the bend of the elbows and knees. Adults whose hands or feet are often exposed to irritating substances, such as chemicals, develop AD on those areas.

Psoriasis is a chronic skin condition that causes raised red patches topped with silvery, scaling skin, usually on the knees, elbows, scalp, and back. The fingernails, palms, and soles of the feet may also be affected. Psoriasis is not contagious. The patches, called plaques, are made up of dead skin cells that accumulate in thick layers. Normal skin cells are replaced every 30 days. In people who have psoriasis, skin cells are replaced every 3 to 4 days. Small patches of psoriasis can often be treated with regular use of hydrocortisone cream. Tar products (lotions, gels, shampoos) may also be useful, although they may increase your skin's sensitivity to the sun. Limited exposure to the sun may also help (protect unaffected skin with sunscreen). Stress may contribute to psoriasis. Stress reduction may help in some cases. See Stress and Distress. Call your doctor if psoriasis covers much of your body or is very red. Extensive or severe cases often need professional care. |
