Eczema or Atopic Dermatitis

Eczema, also known as atopic dermatitis, is an inflammation of the skin which is chronic in nature. Patients having this condition have severe itching in the regions affected by eczema. This condition can also be accompanied by hay fever or asthma. Any part of the skin can be affected by eczema; however, arms and posterior region of the knee are more commonly affected. Eczema has the tendency to flare up for some time and then subside for some time, even a few years. The cause for eczema is not known; although it is believed to occur as a result of inherited predisposition towards a sensitive skin and dysfunction of the immune system.

Eczema or Atopic Dermatitis

Eczema commonly starts during childhood and can continue till adulthood. In some patients, this condition has periodic flare ups and then there is relief for some time, even for some years. There can be severe itching experienced where the patient scratches his/her skin thus making itching and inflammation worse. Scratching also causes a break in the skin which makes the skin susceptible to bacterial infections, particularly Staphylococcus aureus. It is very important to break this itch and scratch cycle.

Treatment comprises of avoiding irritants, such as soaps and using soothing ointments and creams for relieving the itching. Prescription medications, such as corticosteroid creams are also used. Light therapy also helps with eczema.
