Atopic Dermatitis Long Island
Atopic dermatitis: This disease often appears before a child’s first birthday and causes itchy skin that is red, warm, and tender.
This is a common skin disease in children. It is so common that people have given it a few names:
- Eczema (name most people use).
- Atopic (a-top-ic) eczema.
- Atopic dermatitis.
To avoid confusion, we will use the medical term atopic dermatitis.
Children often get atopic dermatitis (AD) during their first year of life. If a child gets AD during this time, dry and scaly patches appear on the skin. These patches often appear on the scalp, forehead, and face. These patches are very common on the cheeks.
No matter where it appears, AD is often very itchy. Infants may rub their skin against bedding or carpeting to relieve the itch.
In children of all ages, the itch can be so intense that a child cannot sleep. Scratching can lead to a skin infection.
Because atopic dermatitis can be long lasting, it is important to learn how to take care of the skin. Treatment and good skin care can alleviate much of the discomfort. Around the world, between 10% and 20% of children have AD. About 1% to 3% of adults have AD. People of all skin colors get AD.
Most people (90%) get AD before their 5th birthday. AD rarely starts when a person is an adult.
AD is much more common today than it was 30 years ago. We are not sure why. We do know that some children have a greater risk of getting AD. The following seem to increase a child’s risk of getting AD:
- Family members have AD, asthma, or hay fever: Does the child’s mother or father have AD? Does a parent have asthma or hay fever? A family history of these diseases remains the strongest risk factor. If one or both parents have AD or an allergic condition, the child is much more likely to get AD. Some children get all 3 diseases. Asthma and hay fever usually appear before the age of 30. People often have asthma and hay fever for life.
- Where child lives: Living in a developed country, city (especially one with higher levels of pollution), or a cold climate seems to increase the risk. For example, Jamaican children living in London are twice as likely to develop AD as those who live in Jamaica.
- Gender: Females are slightly more likely than males to get AD.
- Mother’s age when child born: When the mother gives birth to the child later in her childbearing years, a child is more likely to get AD.
- Social class: AD seems more common in higher social classes.
What causes atopic dermatitis?
Researchers are still studying what causes AD. Through their studies, they have learned that AD:
- Is not contagious: There is no need to worry about catching it or giving it to someone.
- Runs in families: People who get AD usually have family members who have AD, asthma, or hay fever. This means that genes play a role in causing AD.
- Children are more likely to develop AD if one or both parents have AD, asthma, or hay fever.
- About half (50%) of the people with severe AD (covers a large area of the body or is very troublesome) will get asthma and about two-thirds (66%) will get hay fever.
Can certain foods cause atopic dermatitis?
Foods do not cause AD. But some studies suggest that food allergies can make AD worse. Children who have AD often have food allergies to these foods — milk and foods that contain milk (e.g., yogurt and cheese), nuts, and shellfish.
Before you stop feeding your child any foods, talk about this with your child’s pediatrician. Children need certain foods to grow and develop normally.
Researchers continue to study what causes this complex disease. They believe that many things interact to cause AD. These things include our genes, where we live, and the way our immune system works.
How do we diagnose atopic dermatitis?
To diagnose atopic dermatitis (AD), we begin by looking at the child’s skin. We will look for a rash, ask questions as to whether the child has itchy skin. We also need to know whether blood relatives have had AD, asthma, or hay fever.
Sometimes we will perform a patch testing. This medical test is used to find allergies. It involves placing tiny amounts of allergens (substances that cause allergies for some people) on the child’s skin. We will check the skin for reactions. Checks are often done after a few hours, 24 hours, and 72 hours. Studies suggest that some allergens can make AD worse.
Most children’s eczema does not have a clear cause, such as an allergy, but most eczema will improve with good skin care. These tips from dermatologists can reduce the severity and frequency of your child’s flare-ups.
Atopic dermatitis (AD) looks different in infants, children, and adults. The following gives you the signs (what you see) and symptoms (what you feel) for each age group.
AD can begin early. A child may be 2 or 3 months old when AD begins. When AD begins early, it often causes:
- A rash that appears suddenly and:
- makes the skin dry, scaly, and itchy.
- forms on the scalp and face, especially on the cheeks (can appear on other areas of the body).
- can bubble up, then ooze and weep fluid.
- causes itching that may come and go.
- Rubbing against bedding, carpeting, and other things in order to scratch the itch.
- Trouble sleeping.
- Skin infections, common due to rubbing and scratching.
Parents often worry that their babies are getting AD in the diaper area. A babies rarely gets AD in his or her diaper area. The skin stays too moist for AD.
When AD begins between 2 years of age and puberty, the child often has these signs and symptoms:
- A rash that often begins in the creases of the elbows or knees. Other common places for the rash to appear are the neck, wrists, ankles, and/or crease between the buttocks and legs.
- Itchy, scaly patches where the rash appeared.
In time, the skin with AD can:
- Get bumpy, looking like permanent goose bumps.
- Lighten (or darken) where AD appears.
- Thicken, turning leathery to protect itself from constant scratching.
- Develop knots (only on the thickened skin).
- Itch all the time (only on the thickened skin).
- The thickened skin, called lichenification, can itch even when the AD is not flaring.
It is rare for adults to get AD. Most people (90%) get AD before age 5. About half (50%) of people who get AD during childhood continue to have milder signs and symptoms of AD as an adult. When an adult has AD, it often looks different from the AD of childhood. For adults, AD often:
- Appears in the creases of the elbows or knees and nape of neck.
- Covers much of the body.
- Can be especially noticeable on the neck and face.
- Can be especially bad around the eyes.
- Causes very dry skin.
- Causes non-stop itch.
- Causes scaly skin — more scaly than in infants and children.
- Leads to skin infections.
If a person has had AD for years, patches of skin may be thick and darker than the rest of the skin (or lighter). Thickened skin can itch all the time.
Adults who had AD as a child and no longer have AD can have the following:
- Extremely dry skin.
- Skin that is easily irritated.
- Hand eczema.
- Eye problems (eczema on eyelids, cataracts).
Skin Hygiene and Care for Children with Atopic Dermatits
- Bathe your child in warm — not hot — water.
- Limit your child’s time in the bath to 5 or 10 minutes.
- If your child is old enough, a short, warm shower is better than a bath. The less time in water, the better.
- Use a cleanser that is mild and fragrance-free. Do not use bubble bath. Two of our favorites are:
- Cetaphil RestoraDerm Skin Restoring Body Wash
- Dove Deep Moisture Body Wash with Nutrium Moisture
- After bathing or showering, gently pat your child’s skin partially dry.
- If your child has medicine that you apply to the skin, apply medicine when your child’s skin
- is slightly damp, and use the medicine as directed.
- Apply moisturizer on top of the medicine and to the rest of your child’s skin.
Tips for choosing a moisturizer
When selecting a moisturizer, consider choosing a thick cream or ointment.
Some children do better with fragrance-free products, so consider petroleum jelly — an inexpensive, fragrance-free product that works well for many children.
One of our favorite moisturizers for AD is Cetaphil Restoraderm Skin Restoring Moisturizer.
Tips to ease discomfort
- For best results, apply moisturizer at least twice a day when the skin is slightly damp. You want to “trap” moisture under the moisturizer to hydrate the skin. This prevents dryness and cracking. It also can decrease the need for eczema medications.
- Keep your child’s fingernails short and smooth. This decreases the likelihood that scratching will puncture the skin. Putting cotton gloves on your child’s hands at night may help prevent scratching during sleep.
- Keep temperature and humidity levels comfortable. Avoid situations in which the air is extremely dry, or where your child may sweat and overheat. This is the most common trigger of the itch/scratch cycle.
- Using a laundry detergent made for sensitive skin may be beneficial. Scented fabric softener or dryer sheets may contribute to irritation.
- Only use the recommended amount of detergent.
- Use enough water for adequate rinsing.
- Buy clothes without tags because tags can rub against the skin, causing irritation.
- Wash your child’s new clothes before wearing. This will remove excess dyes and fabric finishers, which can irritate the skin.
Good skin care is a key part of gaining control of your child’s eczema. If skin care has not been a regular part of your child’s treatment, you should make an appointment for your child to see a dermatologist.
