What is Atopic dermatitis?
Atopic dermatitis (AD) also known as atopic eczema or eczema As they get older the back of the knees and front of the elbows are the most common area for the rash. In adults the hands and feet are most affected.
The cause is believed to involve a number of factors including: genetics, immune system dysfunction, environmental exposures, and difficulties with the permeability of the skin. The diagnosis is based on the signs and symptoms. Other diseases that need to be excluded are contact dermatitis, psoriasis, and seborrheic dermatitis.
Treatment involves avoiding things that make it worse, daily bathing with application of a moisturising cream afterwards, applying steroid creams when flares occur, and medications to help with itchiness. Antibiotics (either by mouth or topically) may be needed if infections develop.
It affects more than 10% of children in the United States and is more common in younger children. Most people outgrow it. It has been given names like "prurigo Besnier," "neurodermatitis," "endogenous eczema," "flexural eczema," "infantile eczema," and "prurigo diathésique".
