Nickel in a first-generation iPad likely triggered an allergic skin reaction in an 11-year-old boy, a case that highlights an increasingly common condition linked to the rapid adoption of consumer electronics, according to a study published by the American Academy of Pediatrics on Monday. Dr Sharon Jacob and Dr Shehla Admani, who are both dermatologists, studied severe skin rashes afflicting the unidentified 11-year-old boy for more than six months, before discovering that his daily use of an Apple Inc iPad may have brought on the condition. The boys iPad, among the first versions of the device launched in 2010, tested positive for nickel, they said. The dermatologists said a cover only provides coverage of the screen and leaves the back of the device exposed.
