Eczema is a general term used to describe a group of skin diseases in which skin becomes swollen, irritated, and itchy as in a rash. Eczema affects both adults and children, but is most common in babies.
The most common type of eczema is caused by allergy and is called atopic dermatitis. Eczema is not contagious; therefore it does not spread from one person to another. You are more prone to have eczema if your parents or family has a history of eczema and allergic conditions like asthma and hay fever.
Eczema can be triggered by certain substances such as soaps, detergents, cosmetics, jewelry, or sweat. Humidity and psychological stress may also cause eczema.
Eczema causes dry, scaly, red skin that itches or burns. It occurs on the face, neck, and the insides of the elbows, knees, and ankles. In babies, eczema typically occurs on the forehead, cheeks, forearms, legs, scalp, and neck.
Treatment of eczema aims at keeping the skin moist by applying creams or ointments. Corticosteroid creams are applied to decrease the inflammation. If itching is severe, oral antihistamines are prescribed.
In some cases, a short course of oral corticosteroids (prednisolone) is given to control an outbreak of eczema. Cyclosporine is also used in certain cases. Ultraviolet light therapy is another treatment option for eczema. Tacrolimus (Protopic®) and pimecrolimus (Elidel®) are approved as second-line drugs by U.S. Food and Drug Administration for treatment of eczema unresponsive to other treatments.
