On this particular episode, they show a child named Dustin Domine, son of Randy and Shelley Domine. Dustin was born with a rare immune deficiency which confined him to a sterile hospital environment for the first two years of his life. He eventually received a "miraculous" new medical treatment which allowed him to live at home and live a semi-normal life. "Miracles of Medicine!" End of story.
Nearly 30 years later, I can punch that name into Google and find out immediately what became of little Dustin. Unfortunately, the story didn't have a happy ending.
I wonder if the producers of the show had ever imagined the existence of the Internet and the ability to instantly search for names, places and events.
