Atopic dermatitis is very common worldwide and increasing in prevalence. It affects males and females equally and accounts for
10%-20 % of all referrals to dermatologists (doctors who specialize in the care and
treatment of skin diseases). Atopic dermatitis occurs most often in
infants and children, and its onset decreases substantially with age.
Scientists estimate that 65% of patients develop symptoms in the
first year of life, and 90% develop symptoms before the age of 5.
Onset after age 30 is less common and often occurs after exposure of the skin
to harsh conditions. People who live in urban areas and in climates with
low humidity seem to be at an increased risk for developing atopic dermatitis.
About 10% of all infants and young children experience symptoms of
the disease. Roughly 60% of these infants continue to have one or more
symptoms of atopic dermatitis even after they reach adulthood. This means
that more than 15 million people in the United States have symptoms of the disease.
What causes atopic dermatitis?
The cause of atopic dermatitis is not known, but the disease seems to result from a combination of genetic (hereditary) and environmental factors. There seems to be a basic hypersensitivity and an increased tendency toward itching. Evidence suggests that the disease is associated with other so-called atopic disorders such as hay fever (seasonal allergies) and asthma, which many people with atopic dermatitis also have. In addition, many children who outgrow the symptoms of atopic dermatitis go on to develop hay fever or asthma. Although one disorder does not necessarily cause another, they may be related, thereby giving researchers clues to understanding atopic dermatitis.
While emotional factors and stress may in some cases exacerbate or initiate the condition, they do not seem to be a primary or underlying cause for the disorder. In the past, there was some thought that perhaps atopic dermatitis was entirely caused by an emotional disorder.
The word "rash" means an outbreak of red bumps on the body. The way people use this term, "a rash" can refer to many different skin conditions. The most common of these are scaly patches of skin and red, itchy bumps or patches all over the place.
Keratosis pilaris (KP) is a common skin disorder in which small white or red bumps appear around hair follicles on the upper arms, thighs, buttocks, and cheeks. The cause of KP is unknown. There is no cure for keratosis pilaris, and the condition may resolve on its own. Gentle exfoliation, professional manual extraction, chemical peels, and microdermabrasion, along with topical products, are the best treatments for this condition.
Swimmer's ear (external otitis) is an infection of the skin that covers the outer ear canal. Causes of swimmer's ear include excessive water exposure that leads to trapped bacteria in the ear canal. Symptoms include a feeling of fullness in the ear, itching, and ear pain. Chronic swimmer's ear may be caused by eczema, seborrhea, fungus, chronic irritation, and other conditions. Common treatment includes antibiotic ear drops.
