Metal Ions Inactivation by Ion Plating with Necklaces Provoked No Dermatitis with Metal Hypersensitive Patients

Abstract

Metals, especially nickel, have been commonest contact sensitizers from various daily necessities and accessories today. Patients suffering from contact dermatitis are so many that prevention of the dermatitis is necessary. Ion plating is a new industrial technique to seal metal ions in the metal goods, and it was successful to prevent wristwatch dermatitis with metal hypersensitive patients in 1992. This is the second report on the effect of ion plating on the necklaces as prevention for contact dermatitis due to metals. 23 metal hypersensitive patients, among which 22 were sensitized by nickel, agreed to use IP-treated necklace everyday for a month, without using other necklaces. Results: nobody produced dermatitis around the necklace area, when the skin was examined a month later. It is concluded that ion plating is recommendable as a prevention of metal allergies hereafter.
