Eczema is an inflammation of the skin. It is characterized by itchy, erythematous, vesicular, weeping, and crusting patches. Eczema commonly used to describe atopic dermatitis or atopic eczema.
In some languages, dermatitis and eczema are synonyms, while in other languages dermatitis implies an acute condition and eczema a chronic one.
The term eczema is broadly applied to a range of persistent skin conditions. These include dryness and recurring skin rashes that are characterized by one or more of these symptoms: redness, skin swelling, itching and dryness, crusting, flaking, blistering, cracking, oozing, or bleeding.
Areas of temporary skin discoloration may appear and are sometimes due to healed injuries. Scratching open a healing lesion may result in scarring and may enlarge the rash.
Treatment is typically with moisturizers and steroid creams. If these are not effective, creams based on calcineurin inhibitors may be used. The disease was estimated as of 2010 to affect 230 million people globally (3.5% of the population).
Although every type of dermatitis has different symptoms, there are certain signs that are common for all of them, including redness of the skin, swelling, itching and skin lesions with sometimes oozing and scarring.
Also, the area of the skin on which the symptoms appear tends to be different with every type of dermatitis, whether on the neck, wrist, forearm, thigh or ankle.
Although the location may vary, the primary symptom of this condition is itchy skin. More rarely, it may appear on the genital area, such as the vulva or scrotum.
Symptoms of this type of dermatitis may be very intense and may come and go. Irritant contact dermatitis is usually more painful than itchy.
Although the symptoms of atopic dermatitis vary from person to person, the most common symptoms are dry, itchy, red skin. Typical affected skin areas include the folds of the arms, the back of the knees, wrists, face and hands.
Dermatitis herpetiformis symptoms include itching, stinging and a burning sensation. Papules and vesicles are commonly present.
The small red bumps experienced in this type of dermatitis are usually about 1 cm in size, red in color and may be found symmetrically grouped or distributed on the upper or lower back, buttocks, elbows, knees, neck, shoulders, and scalp. Less frequently, the rash may appear inside the mouth or near the hairline.
The symptoms of seborrheic dermatitis on the other hand, tend to appear gradually, from dry or greasy scaling of the scalp (dandruff) to hair loss. In severe cases, pimples may appear along the hairline, behind the ears, on the eyebrows, on the bridge of the nose, around the nose, on the chest, and on the upper back.
In newborns, the condition causes a thick and yellowish scalp rash, often accompanied by a diaper rash.
Perioral dermatitis refers to a red bumpy rash around the mouth.The cause of eczema is unknown but is presumed to be a combination of genetic and environmental factors.
People with eczema should not get the smallpox vaccination due to risk of developing eczema vaccinatum, a potentially severe and sometimes fatal complication.
Bathing once or more a day is recommended. It is a misconception that bathing dries the skin in people with eczema. It is not clear whether dust mite reduction helps with eczema.
There has not been adequate evaluation of changing the diet to reduce eczema. There is some evidence that infants with an established egg allergy may have a reduction in symptoms if eggs are eliminated from their diets.
Benefits have not been shown for other elimination diets, though the studies are small and poorly executed.
Establishing that there is a food allergy before dietary change could avoid unnecessary lifestyle changes.
People can also wear clothing designed to manage the itching, scratching and peeling. Soaps and detergents should not be used on affected skin because they can strip natural skin oils and lead to excessive dryness.

Prevention
There is no good evidence that a mother's diet during pregnancy, the formula used, or breastfeeding changes the risk. There is tentative evidence that probiotics in infancy may reduce rates but it is insufficient to recommend its use.People with eczema should not get the smallpox vaccination due to risk of developing eczema vaccinatum, a potentially severe and sometimes fatal complication.
