Eczema and dermatitis - patch test diagnosis effective
Standard screening
using a patch test is the most reliable and useful method in
diagnosing patients suffering with allergy-induced eczema and
dermatitis, according to researchers at the Institute of
Occupational Medicine, Chinese Academy of Preventive Medicine,
Beijing, China.
Monitoring 720
patients, the researchers found that more than 50 per cent (376) of
the patients showed a worsening of symptoms when exposed to one or
more allergens. The positive reactions were most noted for
cobaltsulphate (118 cases, 6.4%), potassium dichromate (115 cases,
16.0%), nickelchloride (108 cases, 15.0%) mercuric chloride (106
cases, 14.7%), Beihai detergent powder (63 cases, 8.8%), and p-phenylene
diamine (50 cases, 6.9%).
The report concludes that the standard screening for allergens is
extremely
valuable in trying to understand some of the underlying causes
and triggers
of dermatitis and eczema.
