World - smh.com.au : March 5, 2006 A 15-YEAR-OLD girl with a peanut allergy did not die from kissing her boyfriend after he ate peanut butter but from another cause, a coroner has ruled. But coroner Michel Miron would not reveal what caused Christina Desforges's death, saying he simply wanted to speak out before her case was cited by the food allergies association. 'The [association] intended to use the Desforges case to launch an education campaign,' Mr Miron said. 'I had to tell them the cause of death was different than first believed.' At the time of Desforges's death last November, officials said doctors had been unable to treat her allergic reaction to the kiss. Thinking she was having an asthma attack, Desforges had desperately searched for medicine. Friends called an ambulance as her breathing grew laboured but she collapsed. She died four days later in a Quebec hospital."
