Atopic dermatitis (AD) also known as atopic eczema[1] is a type of eczema, an inflammatory, relapsing, non-contagious and pruritic (itchy) skin disorder.[2] It has been given names like \"prurigo Besnier,\" \"neurodermitis,\" \"endogenous eczema,\" \"flexural eczema,\" \"infantile eczema,\" and \"prurigo diathsique\".[3] <\/p>\n
The skin of a patient with atopic dermatitis reacts abnormally and easily to irritants, food and environmental allergens and becomes very itchy, which leads to scratching, redness, and flaky skin. It is sometimes called \"the itch that rashes\" because the itchiness precedes the rash, and scratching the itchy skin may cause the rash.[4] It also becomes vulnerable to surface infections caused by bacteria. The skin on the flexural surfaces of the joints (for example inner sides of elbows and knees) are the most commonly affected regions in people. <\/p>\n
Atopic dermatitis often occurs together with other atopic diseases like hay fever, asthma and allergic conjunctivitis. It is a familial and chronic disease and its symptoms can increase or disappear over time. Atopic dermatitis in older children and adults is often confused with psoriasis. Atopic dermatitis afflicts humans, particularly young children, and is also a well-documented disease in domestic dogs. <\/p>\n
Although there is no cure for atopic eczema, and its cause is not well understood, it can be treated very effectively in the short term through a combination of prevention (learning what triggers the allergic reactions) and drug therapy. <\/p>\n
Atopic dermatitis most often begins in childhood before age 5 and may persist into adulthood. For some, it flares periodically and then subsides for a time, even up to several years.[5] Yet, it is estimated that 75% of the cases of atopic dermatitis improve by the time children reach adolescence, whereas 25% continue to have difficulties with the condition through adulthood.[6] <\/p>\n
Although atopic dermatitis can theoretically affect any part of the body, it tends to be more frequent on the hands and feet, on the ankles, wrists, face, neck and upper chest. Atopic dermatitis can also affect the skin around the eyes, including the eyelids.[7] <\/p>\n
In most patients, the usual symptoms that occur with this type of dermatitis are aggravated by a Staphylococcus aureus infection, dry skin, stress, low humidity and sweating, dust or sand or cigarette smoke. Also, the condition can be worsened by having long and hot baths or showers, solvents, cleaners or detergents and wool fabrics or clothing. <\/p>\n
Atopic dermatitis is also known as infantile eczema, when it occurs in infants. Infantile eczema may continue into childhood and adolescence and it often involves an oozing, crusting rash mainly on the scalp and face, although it can occur anywhere on the body.[8] The appearance of the rash tends to modify, becoming dryer in childhood and then scaly or thickened in adolescence while the itching is persistent. <\/p>\n
Approximately 50% of the patients who develop the condition display symptoms before the age of 1, and 80% display symptoms within the first 5 years of life.[6] <\/p>\n
Symptoms may vary from person to person but they are usually present as a red, inflamed, and itchy rash and can quickly develop into raised and painful bumps.[9] The first sign of atopic dermatitis is the red to brownish-gray colored patches that are usually very itchy. Itching may become more intense during the night. The skin may present small and raised bumps which may be crusting or oozing if scratched, which will also worsen the itch. The skin tends to be more sensitive and may thicken, crack or scale. <\/p>\n
