Dermatitis/Eczema

Dermatitis/Eczema

 

Dermatitis is a common skin reaction which is characterised by a red and itchy rash, which can sometimes look swollen. This rash can flare up occasionally or be present all the time. Some people use the word "eczema" to describe dermatitis, and these two words can be used interchangeably.

Different types of dermatitis exist.

Some of the most common types of dermatitis/eczema are:

Atopic dermatitis/eczema

Atopic dermatitis usually occurs in people who have a tendency to get allergies, or who also have asthma or hayfever (allergic rhinitis). All three of these conditions (atopic dermatitis, asthma and hayfever) are closely related. Often these conditions run within families with a parent, child or sibling also affected.

Most people develop this condition in childhood, though it can occur at any age. The rash is usually intensely itchy and commonly occurs in the skin flexures (such as behind the elbows or knees). Sometimes the skin may be broken.

Although the exact cause is unknown, atopic dermatitis can be brought on by allergies such as reactions to certain foods, dust mites, pollen or animal fur, or made worse by irritants such as woollen clothes, perfumes, soaps and chemicals. Stress or changes in the weather can also cause flare-ups (periods of time where the skin becomes more itchy and inflamed than usual).

Atopic dermatitis may be divided according to the age of onset into three different types.

Infantile atopic dermatitis

Infantile atopic dermatitis usually starts between four and six months of age. The baby develops a red rash, which may weep. It appears on the cheeks and may spread to the forehead, scalp and the backs of arms and legs. In severe cases it may involve the whole body. This type of dermatitis usually disappears between the ages of three and five years.

Childhood atopic dermatitis

Childhood atopic dermatitis may follow infantile atopic dermatitis, or it may start for the first time between the ages of two and four years. It tends to occur in the creases of the elbows, behind the knees, across the ankles and also may involve the face, ears and neck. This form of dermatitis usually disappears by the age of 10, but may continue into adulthood.

Adult atopic dermatitis

Adults with atopic dermatitis usually have large areas of itchy, reddened, weeping skin. The elbow creases, wrists, neck, ankles and behind the knees are areas especially affected. The condition tends to improve in middle life and is unusual in elderly people.

Allergic contact dermatitis

This is a skin reaction which results from contact with something you are allergic to. Common substances that cause allergies include hair dye, nickel in jewellery, sticking plasters, latex in rubber gloves, plants, cosmetics, dyes or chemicals in clothing. The area that has been in contact with the allergen usually develops a very red lumpy rash.

Irritant contact dermatitis

Irritant substances such as soaps, disinfectants, chemicals, detergents and solvents can remove natural oils from your skin. Repeated contact can make skin red, itchy and dry and lead to scaling, cracking and roughness. Hands are the area most commonly affected.

Seborrhoea dermatitis

This is a common, harmless, scaling rash which can affect the face, scalp, eyebrows, and eyelid edges. It is more likely to occur in places where the skin is oily. You may need to discuss treatment with a doctor or pharmacist as often this type of dermatitis can be hard to manage.

Cradle cap

Cradle cap is a scaly, crusty, patchy, greasy skin rash that commonly appears on the scalp of recently born babies. It is not usually itchy and most babies are not bothered by it. It is uncertain whether it is the same condition as seborrhoeic dermatitis.

 

Nobody really knows what causes cradle cap but may be due to either overactive sebaceous glands in the skin of new-born babies, or a yeast infection. In most babies the rash clears up by the time the baby is one year old.

See Your Pharmacist or Medical Professional

If you have a weakened immune system, serious medical condition, or the person with the eczema/dermatitis is a young child, you should always talk to a pharmacist. Also talk to a pharmacist if:

The skin is broken, weeping or painful or is making you very uncomfortable

There are signs of infection, such as pus, swelling, redness or warmth

There are any vesicles, which look like small blisters filled with clear fluid

The area has white patches or silvery scales

The skin has become tough and leathery

You have tried treating your skin but it has not improved

Your skin problem is related to your occupation or a regular habit (such as washing hands)

The rash has spread, worsened or lasted for more than three weeks

The cradle cap has worsened or is bothering your baby

You are not sure what type of skin problem you have

If you have allergies to topical medicines.

Treatment Tips

Tips for atopic dermatitis/eczema:

Use a moisturiser or emollient frequently

Try to avoid scratching – keep fingernails short

Anti-itch products may be helpful

Choose a mild soap or soap substitute

Use lukewarm water in baths or showers

Pat your skin dry – do not rub it – then apply a moisturiser or emollient

Choose cotton clothing and bed linen

Using a laundry detergent formulated for sensitive skin and avoiding fabric softeners may help.

Tips for allergic contact dermatitis:

Try to identify the substance causing the allergy and avoid it in future

Your doctor can arrange for you to have allergy tests if necessary.

Tips for irritant contact dermatitis:

Avoid contact with substances you know irritate your skin

Use a barrier cream or gloves to protect your hands

Use a mild soap or soap substitute to prevent loss of natural skin oils since normal soap is very drying on the skin.

Tips for seborrhoeic dermatitis

Use an antifungal shampoo or lotion (see dandruff) and occasionally topical corticosteroids

Ask for further advice if the condition persists.

Tips for cradle cap

Use a mild baby shampoo and brush baby's hair softly with a soft baby brush

Baby oil or mineral oil can also soften scales allowing easier removal – leave on for 5 to 10 minutes then brush off

Do not use olive oil as this can cause overgrowth of naturally occurring yeast thought to be associated with cradle cap.
