Title Metal allergy in Singapore
Bibliographic information 2005, Vol.52, p.130-132. 7 ref.
Abstract This study examined the frequency of metal allergy among patients diagnosed with allergic contact dermatitis in the National Skin Centre of Singapore from 2001 to 2003. The frequency of positive patch tests to the following metals were: nickel 19.9%; chromates 5.6%; cobalt 8.2%; gold 8.3%. After declining from 1984 to 1990, chromate and cobalt allergies have since been steadily increasing. The most common sources of chromate allergy were cement, leather and metal objects. Most positive patch tests to cobalt are regarded as co-sensitization due to primary nickel or chromate allergies. There has also been a steep increase in positive patch tests to gold from 2001 to 2003.
