Eczema is a general term that describes several different conditions in which skin is inflamed, red, scaly, and itchy. Eczema is a common skin condition, and atopic dermatitis (also called atopic eczema) is one of the most common forms of eczema.Eczema can occur in adults or children. The condition is not contagious.
What Causes Atopic Eczema?
The cause of atopic eczema is not known, but the condition often affects people with a family history of allergies. Many individuals with eczema also have hay fever and/or asthma or have family members with those conditions.
Some factors can trigger a flare-up of eczema or make eczema worse, but they do not cause the condition. Eczema triggers include stress, skin irritants (including soaps, skin care products, or some fabrics), allergens, and climate/environment.
What Are the Symptoms of Atopic Eczema?
The appearance of eczema can vary from person to person. In adults, eczema occurs most frequently on the hands and elbows, and in “bending” areas such as the inside of the elbows and back of the knees. In young children, eczema is often seen on the elbows, knees, face, neck, and scalp. Signs and symptoms of atopic eczema include:
- Skin redness
- Dry, scaly, or crusted skin that might become thick and leathery from long-term scratching
- Formation of small, fluid-filled blisters that might ooze when scratched
- Infection of the areas where the skin has been broken
How Is Atopic Eczema Diagnosed?
Atopic eczema usually is diagnosed with an analysis of a person’s history of symptoms and with an exam of the skin. A doctor might test an area of scaly or crusted skin to rule out other skin diseases or infections.
How Is Atopic Eczema Treated?
Atopic eczema can be treated with medications, including over-the-counter creams and ointments containing the steroid hydrocortisone (for example, Cortizone-10, Cort-Aid, Dermarest Eczema, Neosporin Eczema). These products may help control the itching, swelling, and redness associated with eczema. Prescription-strength cortisone creams, as well as cortisone pills and shots, are also used for more severe cases of eczema
Can Atopic Eczema Be Prevented?
Currently, there is no effective strategy for preventing atopic eczema, but the symptoms of the condition can improve. To improve the signs of eczema:
- Reduce stress
- Avoid scratchy materials (for example, wool) and chemicals such as harsh soaps, detergents, and solvents
- Moisturize frequently
- Avoid sudden changes in temperature or humidity
- Avoid situations that cause sweating and overheating
