CHECK UP:Contact dermatitis is caused by an allergic or irritating reaction to certain substances
SINCE SCHOOL finished I've been working in a shop where I carry out different duties including till work, shelf stacking and sandwich making. But last week I suddenly developed a red, itchy and blistered rash on my hands. I have been taken off washing-up duties in case that detergent was the problem, but it hasn't gone away. What could be causing it?
It sounds like you have developed contact dermatitis. Contact dermatitis is inflammation of the skin, caused by an allergic or irritating reaction to contact with certain substances. When the reaction comes on slowly it is known as chronic dermatitis. When it develops suddenly, as in your experience, it is referred to as acute contact dermatitis.
Many substances can bring on dermatitis. Irritation of the skin is commonly caused by detergents or soaps, solvents, oils, acids and alkalis. Susceptible individuals may also suffer an allergic reaction to plants, chemicals in perfumes, cosmetics or certain jewellery.
Coins containing nickel, chromate (found in leather and cement) and dyes are common precipitants. Contact with resins, glues and some medicines can also trigger the problem. The other common product that can cause a reaction is rubber (latex) so if you have been wearing rubber gloves they could be the cause of the problem.
I wear gloves when preparing sandwiches and rolls, so perhaps they are the cause. How can I know for sure?
The only way to accurately determine the cause of the reaction is to have a patch test carried out. This involves various substances being applied to the skin in order to find which one(s) you react to.
You should see your doctor who will recommend an anti-inflammatory cream containing hydrocortisone to help the rash.
Barrier creams and moisturisers such as E45 are also useful in preventing a recurrence of the problem.
Your doctor may refer you to a dermatologist for patch testing of the problem. If you are found to be allergic to the rubber in the gloves, then using ones that have a cotton lining may help.
