**2. Definition**

Atopic Dermatitis is a chronic relapsing inflammatory condition of the skin that occurs most frequently in childhood and may spontaneously resolve or continue throughout a person's life span leading to lifelong sensitivity to irritants and allergens (Habif, 2008). It occurs as a result of several interrelated factors including genetic, immunologic and environmental issues, which ultimately cause a disruption in the epidermal barrier function leading to the development of dry, pruritic skin. The itching can be severe lasting throughout the day and worsening at night, which can lead to sleep disruptions and dramatically reduce the patients' quality of life (Bieber, 2008). Episodes of AD can be triggered by events such as psychological stress, exposure to irritants and allergens or as a result of seasonal or climate changes (Habif, 2008). Additionally, patients with AD are at an increased risk of developing infections especially due to *Staphylococcus Aureus* and Herpes Simplex Virus, asthma and allergic rhinitis (Bieber, 2008).
