Dry Skin & Eczema
What
are the symptoms of this condition?
Eczema is a term used to describe a number of skin conditions
characterised by flakiness, itching, redness and sometimes
weeping of the skin. The term 'dermatitis' is sometimes used
interchangeably with eczema to indicate the same condition.
It may be confined to one or two small areas of the body,
or, in some cases, it may affect large areas of the body.
The severity of the symptoms can vary considerably from person
to person, and also over time with the same person.
Thickening of the skin
can occur in severe cases, and the inflamed areas may feel
very itchy and hot. Because of the intense irritation, excessive
scratching of the skin may increase the risk of a secondary
infection in the affected areas.
All ages may be affected;
childhood eczema is a common hereditary condition which affects
around one in every eight babies, and may be classed as 'atopic
eczema' - that is, eczema which is related to a family history
of common allergic conditions including eczema, hay fever,
and asthma, all of which have a similar underlying cause (it's
quite common for children with eczema to suffer from one or
both of these other conditions too). Most commonly, eczema
occurs on the inner creases of the elbows and knees in children,
and on the face and neck in babies. Childhood eczema generally
first appears between the ages of 6 months and 2 years; if
you already have one child with eczema, there is a one in
four chance that your next child will have it too, although
this risk is increased if both parents suffer from the symptoms.
However, babies who are breast-fed are less likely to suffer
from eczema. It is unclear whether this is due to an intolerance
to cows' milk, or to nutrients in breast milk which are not
found in cows' milk.
Childhood eczema often
diminishes by the mid-teens, with many cases settling down
before the age of 6; however, the symptoms may reappear later
in adult life, especially in times of stress, when it commonly
reoccurs on the hands.
What
is the cause of the condition?
As there are several different types of eczema, there are
many possible causes.
Atopic eczema, an inherited
condition most commonly found in childhood, is often seen
in children who also suffer from hay fever or asthma; there
may also be an allergic reaction to certain factors in the
child's environment which makes the symptoms worse.
Adult eczema may be
a recurrence of childhood eczema, and can be triggered by
sensitivities to environmental factors, or stress. Allergic
reactions can act as triggers for eczema. Many substances
can, with repeated exposure, cause the symptoms of eczema
or dermatitis. This may be a problem that develops at work
or in the home; chemicals found in some industries, such as
acids, alkalis, dyes, oils or bleaches are known to trigger
eczema, and household products, including detergents, can
also precipitate attacks. Sometimes the reaction follows long
and repeated exposure; sometimes it occurs on first contact.
Contact dermatitis
is the name given to a skin reaction which is initiated by
skin contact with certain materials, and can develop with
exposure to materials that in most individuals do not usually
cause problems; nickel in watch straps is a common example.
Some make-up products, rubber, some glues and even plants
can be irritant to certain individuals. Eczema-like skin rashes
and irritation may occur in later life or in the elderly.
This probably results from a slow decline in the ability of
the sebaceous (sebum producing) glands, attached to the hair
roots and found all over the body, to function properly. Sebum
is an oily substance that is used to lubricate the surface
of the skin and to keep it flexible; if insufficient quantities
are produced, the skin can become dry and scaly and is easily
irritated.
Sunshine is good for
eczema - although the skin does get itchy if becomes too hot,
so it's important to avoid over-exposure to the sun, and always
use a sunscreen to prevent burning. However, the ultra-violet
(UV) component in sunlight can, in a small number of individuals,
cause a 'photophobic' or light-sensitive eczema rash. Some
drugs and medications are known to cause this as a side effect.
Complicating this particular type of eczema is the difficulty
of minimising exposure to sunlight; strong sunblock creams
are generally recommended wherever possible. If you are concerned
that the medicines you are taking may be responsible for an
eczema-like reaction, the Pharmacy2U pharmacists can give
you more advice.
What
complications might occur?
Eczema tends to be a long term, or chronic, condition. In
the vast majority of cases, it can be controlled without leading
to any serious complications. However, for a small number
of people, the eczema can be very severe and may spread over
a large area of the body. The intensity of the inflammation
and the damage caused to the structure of the skin may cause
permanent scarring; persistent scratching, or otherwise damaging
the inflamed and weakened areas of skin, can introduce bacterial
infections, which will require attention from your doctor.
Complications arising
from eczema can be social in nature, as well as physical;
if the rash is on the face or other exposed parts of the body,
it can be unsightly and may be damaging to a person's self-esteem,
especially in children and young adults. However, there are
many products available which can help to minimise the discomfort
and the visible symptoms which are common in eczema.
What
can I do to treat myself?
Effective self-treatment depends on finding the causative
factors, if any, and eliminating or avoiding them, and the
use of suitable soothing and emollient creams to hydrate the
skin, and medications to ease the discomfort of the rash if
necessary. Further details of the medications and remedies
available for the relief of eczema that can be purchased from
Pharmacy2U will follow in the next section.
Childhood eczema
Although there is no cure for childhood eczema, it is usually
possible to keep the condition under control. Emollients are
the main therapy used by doctors and dermatologists in the
treatment of eczema, and should form the basis of regular
daily treatment for childhood eczema. These products leave
an oily layer on the skin which reduces moisture loss and
rehydrates the skin. Roughness and scaling are reduced, and
itching and irritation are relieved.
Children with eczema
may benefit from using an emollient bath product; these are
formulated to work with the bath water to rehydrate and moisturise
the skin. The water penetrates the skin and is then sealed
in by the emollient, which creates a protective barrier. Bathing
helps keep the skin free from crusts and scales, which in
turn helps to prevent infection.
Emollient creams may
be used between bathing, whenever required, to soothe irritation
and so help prevent scratching. However, most children will
suffer from eczema flare-ups from time to time; areas of skin
then become red and inflamed. Flare-ups can be made worse
by bacteria which live on the skin An antiseptic bath emollient
will reduce the level of bacteria on the skin, at the same
time as moisturising it and relieving irritation.
Your GP may also prescribe
a topical steroid cream or ointment, such as hydrocortisone,
to be applied to inflamed areas. If the inflammation leads
to infection, an antibiotic may be prescribed.
You can make your home
environment less likely to aggravate your child's eczema.
Choose cotton underclothes and bed linen, and avoid wool or
synthetic materials next to the skin; cotton helps keep the
skin cool, and allows it to 'breathe'. Wash clothing and bedclothes
using a mild soap product, and make sure everything is rinsed
thoroughly. Even the mildest soap can cause skin dryness and
worsen the condition; use a bath emollient or an emollient
cleansing bar instead of soap. Pets such as cats and dogs
often aggravate eczema. They don't have to come into direct
contact with the child to cause a problem, so it really is
best not to have any furry pets in the house. Avoid freshly
mown grass, as children with eczema are often allergic to
grass pollen; and finally, ban smoking in the home - tobacco
fumes may irritate the skin further.
Adult eczema
In adults, many cases of eczema or dermatitis seem to result
from exposure to allergens (substances that can trigger an
allergic reaction). Limiting the extent and severity of the
skin rash will be made much easier and more effective if any
allergens can be identified.
As mentioned above,
many common household or workplace substances and materials
can cause eczema symptoms; this is often the result of repeated
exposure over long periods of time. Detergents, used for washing
clothes or in washing-up liquids, are a likely cause of rashes
on the hands, fingers and wrists. This is a form of contact
dermatitis and is mainly due to constant exposure to the substance.
As well as treating the rash with appropriate creams or ointments,
you should avoid the allergen wherever possible; wearing gloves
when washing-up or washing clothes should help.
Eczema rashes which
appear on the face, around the hair line, or on the scalp,
may be caused by a reaction to make-ups, soaps or shampoos.
Strong perfumes and scents in skin products are not always
well tolerated by people with sensitive skins; preservatives
and other chemical constituents in make-ups present similar
problems, and this type of reaction may only become apparent
after a prolonged period of use. If you suspect a contact
reaction of this kind, try switching to shampoos and soaps
that are unperfumed and labelled as hypoallergenic. Similarly,
choose hypoallergenic make-up products.
Men are not immune
to these problems either; shaving preparations can cause face
rashes, and the alcohol present in aftershaves can be irritant,
as can perfumes and fragrances in aftershaves and shaving
creams or soaps. Try to choose a product that is hypoallergenic
and that contains few substances likely to irritate the skin.
What
treatments are available for me to purchase?
A wide range of products can be purchased to help you manage
eczema or dermatitis. Advice can be sought from the Pharmacy2U
pharmacist if you need assistance on selecting suitable products.
Treatments for eczema and other dry skin conditions include
emollients (moisturisers), hydrocortisone and anti-pruritics
(anti-itch preparations).
Emollients
The most important factor in treating eczema is keeping the
skin well moisturised. As the skin becomes dry, inflammation
increases as does itching. Emollients help to smooth, sooth
and moisturise the skin but their effects are quite short-lived.
Therefore, they should be applied frequently to the affected
skin and should be used continuously to prevent 'flare-ups'.
It is also important to use emollients liberally. Aqueous
Cream is a useful and cheap emollient, which can also be used
as a soap substitute. However, many people find more oily
products such as Balneum, Diprobase and Unguentum M are more
effective and longer lasting. E45 and Diprobase are also more
effective and have the advantage of being easy to apply. It
is advisable to try a range of products, as different products
suit different people. Rarely, there may be an allergic reaction
to one of the ingredients; if you believe this has occurred
contact the Pharmacy2U pharmacist for advice.
Bathing removes natural
oils from the skin and can make the symptoms of eczema worse.
There are a number of products that may be used in the bath
or shower to prevent this, including E45 Bath and products
in the Oilatum and Balneum ranges.

Hydrocortisone
Hydrocortisone is a mild steroid which may be used on the
skin to treat contact/allergic dermatitis, mild to moderate
eczema and insect bites. It is an anti-inflammatory and will
reduce redness, inflammation and itching. It is useful in
treating mild eczema flare-ups but may only be used for up
to 7 days and should not be used on the face or anogenital
areas, on broken or infected skin, on children under 10 or
in pregnant or breast-feeding women.
Anti-pruritics
Anti-pruritics help to reduce itching on the skin. Products
include Eurax Cream and Lotion, and E45 Itch Relief Cream.
These should be used with care as sensitivity reactions to
the ingredients can occur.

What
treatments are available from my doctor?
Severe cases of eczema, where there is much inflammation of
the skin, weeping or infection, will need advice and treatment
from a doctor or a dermatologist. There are several treatments
that can be prescribed to deal with severe eczema. It may
require a potent topical steroid to reduce the inflammation.
If the eczema has become infected then antibiotic treatment
may be required.
What
additional investigations might be needed?
Many cases of eczema have an allergic component; isolating
and identifying the responsible allergen(s) can be undertaken
in specialist units, in cases where other measures have failed.
Any
other information I should have?
Self-help and advice groups do exist for sufferers of eczema.
The National Eczema Society provides information on how to
live with eczema and advice on treating and managing the condition.
