Eczema (atopic dermatitis to doctors) has always been related to
allergic diseases such as asthma, seasonal allergies and food allergies. When
many people in a family have allergies, a child in that family has a greater
risk of having eczema.
Recent research has found that the gene responsible for eczema causes a
lack of a certain fatty substance on the skin surface that holds moisture in
the skin. Without that substance, the skin loses moisture, dries out and
cracks. Normal, moist skin is a perfect protective barrier against substances
on the skin surface that could cause irritation. When skin is dry and cracked,
those irritants can get into the skin and cause the body’s immune system to
react with redness and itching. This reaction can occur even if the child is
not actually allergic to the irritant, which explains why some children with
eczema may have negative allergy testing.
Eczema causes patches of scaling, red, itchy, skin. Areas of skin that
repeatedly go from wet to dry are especially susceptible. In infants and young
children, areas that get drooled on - the cheeks, neck and area behind the ears
along with the scalp, arms and legs are often involved. In older children,
areas that collect sweat such as the creases in front of the elbow or behind
the knees are often worse. A child who frequently washes and dries his hands
may have “glove-like” eczema. Athletes may develop eczema patches from sweating
under their protective pads.
When the skin’s normal protective
barrier is broken, it can also allow infectious agents – bacteria, viruses and
fungus – to invade the skin. Sometimes, when an eczema outbreak is especially
resistant to treatment, it is because the area has a secondary infection that
needs to be treated along with the eczema. Some bacterial and viral infections
can become severe – even life-threatening.
Children with eczema not only suffer pain and itching, they can also
have anxiety, embarrassment and emotional distress. They can have sleep
disturbances that can lead to poor school performance and even resemble attention
deficit disorder. People often react negatively when they see a child with the
rash or worry that their children could “catch it”.
To successfully deal with their child’s eczema, parents need to think in
terms of long-term prevention rather than treatment. If the child does have
allergies that bring on the eczema, those allergic agents must be avoided.
Repeated moisturizing, especially after the skin has been wet, is important.
Too often, parents let up on skin care when the child is dong well and only
react to outbreaks of eczema, Moisturizing should be kept up even when
a child doesn’t have a rash. For a basic moisturizer, try different
over-the-counter creams, lotions or oils until you find which one that works best
for your child with the least irritation.
Bathing can be done from once a day to three times a day during
outbreaks. Use a mild, additive-free soap. Some doctors now recommend putting
some bleach in the water once a week to decrease the bacteria count on the child's skin. After the bath, lightly pat the skin dry and then apply the moisturizer while the skin is still slightly wet. Apply
moisturizer to both the affected areas and the clear areas of skin. Areas that
are repeatedly exposed to moisture may need repeated application through the
day. An over-the-counter oral antihistamine can be given at night to help the
child sleep or given during the day to decrease itching. It is often said to treat eczema like "an itch that rashes rather than a rash that itches". In addition to
moisturizers, low-dose corticosteroid creams are available without a prescription
and can be used to both prevent and treat outbreaks. Stronger steroid creams
need a prescription and should be used sparingly under a physician’s guidance
because they can cause permanent scars. Finally, there are other medications
called calcineurin inhibitors that are used for eczema but they also need a
prescription. If an area of eczema doesn’t respond to treatment, check with
your child’s caregiver to be sure that the area doesn’t have a secondary
infection.
