ATOPIC DERMATITIS
DESCRIPTION |

Atopic dermatitis refers to a wide range
of diseases that are often associated with stress and allergic
disorders that involve the respiratory system, like asthma and hay
fever. Although atopic dermatitis can appear at any age, it is most
common in children and young adults. Symptoms usually abate before
the age of 25 and do not affect the patient's general health.
About one in ten babies develop a form of atopic dermatitis called
infantile eczema. Characterized by skin that oozes and becomes
encrusted, infantile eczema most often occurs on the face and scalp.
The condition usually improves before the child's second birthday,
and medical attention can keep symptoms in check until that time.
When atopic dermatitis develops after infancy, inflammation,
blistering, oozing, and crusting are less pronounced. The patient's
sores become dry, turn from red to brownish-gray, and skin may
thicken and become scaly. In dark-skinned individuals, this
condition can cause the complexion to lighten or darken. Itching
associated with this condition is usually worst at night. It can be
so intense that patients scratch until their sores bleed, sometimes
causing scarring and infection.
Atopic dermatitis affects about 3% of the population of the United
States, and about 80% of the people who have the condition have one
or more relatives with the same condition or a similar one. Symptoms
tend to be most severe in females. Atopic dermatitis can erupt on
any part of the skin, and crusted, thickened patches on the fingers,
palms, or the soles of the feet can last for years. In teenagers and
young adults, atopic dermatitis often appears on one or more of the
following areas:
Elbow creases
Backs of the knees
Ankles
Wrists
Face
Neck
Upper chest
Palms and between the fingers. |
