Atopic dermatitis, commonly known as eczema, is an allergic skin condition characterized by dry, itching skin. Itching leads to scratching that can produce a thick rough skin which is characteristic of long-standing atopic dermatitis. Atopic dermatitis runs in families along with asthma and allergic rhinitis. Like asthma, a variety of conditions can aggravate it, including infection, stress, food allergy and sweating. It may be found on the back of the legs and front of the arms.
Adults often have problems with their hands.
This is expecially true of people whose hands are in frequent contact with water. Therapy is based on avoidance of allergens and maintenance of good skin care. Itching is often worse at bedtime. Antihistamines reduce itching but should be used only if necessary. Steroid creams are useful in severe cases, but should be used for a short time only.
