question: What is the name of the person that was diagnosed with a potentially lethal oral infection?
context: In late 1996, after more than five years of addiction to heroin, Frusciante quit it cold turkey. However, months later he was still unable to break addictions to crack cocaine and alcohol. In January 1998, urged by longtime friend Bob Forrest, Frusciante checked into Las Encinas, a drug rehabilitation clinic in Pasadena, to begin his recovery. Upon arrival, he was diagnosed with a potentially lethal oral infection, which could only be alleviated by removing all of his rotten teeth and replacing them with dental implants. He also received skin grafts to help repair the abscesses on his ravaged arms. About a month later, Frusciante checked out of Las Encinas and re-entered society.Fully recovered and once again healthy, Frusciante began living a more spiritual, ascetic lifestyle. He changed his diet, becoming more health-conscious and eating mostly unprocessed foods. Through regular practice of vipassana and yoga, he discovered the effect that self-discipline has on the body. To maintain his increased spiritual awareness and reduce distraction from his music, Frusciante decided to abstain from sexual activity stating: "I'm very well without it." All of these changes in his life have led him to a complete change in his attitude toward drugs:
  I don't need to take drugs. I feel so much more high all the time right now because of the type of momentum that a person can get going when you really dedicate yourself to something that you really love. I don't even consider doing them, they're completely silly. Between my dedication to trying to constantly be a better musician and eating my health foods and doing yoga, I feel so much more high than I did for the last few years of doing drugs.
  At this point I'm the happiest person in the world. These things do not fuck with me at all, and I'm so proud of that—you don't know how proud I am. It's such a beautiful thing to be able to face life, to face yourself, without hiding behind drugs; without having to have anger towards people who love you. There are people who are scared of losing stuff, but you don't lose anything for any other reason than if you just give up on yourself.
