Atopic Eczema
Medical Questions » Atopic Eczema
| Name: Atopic Eczema |
| Also known as: Atopic Dermatitis |
| An abnormal reaction of skin to an irritating substance. |
Causes of Atopic Eczema
Atopy is the tendency to develop a sudden, excessive sensitivity to a substance. It is similar to allergy, but not the same, as no previous exposure to the substance is required. The rash may be triggered by changes in climate or diet, stress or fibers in clothing, and tends to occur in areas where the skin folds in upon itself (eg. groin, arm pits, inside elbows, eyelids). It is more common in winter and urban areas, has a peak incidence between 6 and 12 months of age, and there is an hereditary tendency. Up to a third of the population are atopic, but only 5% of children will develop this skin condition. |
Symptoms of Atopic Eczema
Extremely itchy rash, but any blisters that form are rapidly destroyed by scratching which changes the normal appearance of the eczema, so that it appears as red, scaly, grazed skin that may be weeping because of a secondary bacterial infection. With repeated irritation, the skin may become hard, thickened, and pebbly. |
Tests for Atopic Eczema
In most cases, the responsible substance cannot be identified. Skin and blood tests can be performed to tell if a person has an atopic tendency. |
Treatment for Atopic Eczema
Soothing moisturizing creams, steroid creams to reduce inflammation and itch, and soap substitutes to prevent drying the skin. In severe cases, steroid and antihistamine tablets are necessary.
|
Complications of Atopic Eczema of its treatment
A secondary infection of the rash may occur, resulting in enlarged and tender lymph nodes in the neck, groin and armpit. |
Likely Outcome of Atopic Eczema
No cure, but effective control can be obtained in the most cases. The majority of children grow out of the condition. |
