After Gloria Monty first left the series in 1987, General Hospital entered into a transitional phase that lasted until Wendy Riche took the position of executive producer in 1992. Under Riche, the show gained critical acclaim for its sensitive handling of social issues. In 1994, Riche started an annual Nurses' Ball, a fundraiser and HIV/AIDS awareness event both on the show and in real life. Later that year, a heart transplantation storyline involves the death of eight-year-old (daughter of Dr. Tony Jones and Bobbie Spencer) in a bus crash and the subsequent donation of her heart to her dying cousin Maxie Jones. Shortly afterwards, Monica Quartermaine (Leslie Charleson) begins a long battle with breast cancer, which leads to her adopting Emily Quartermaine, the orphaned young daughter of Monica's friend from treatment. General Hospital was also praised for the love story of teenagers Stone Cates (Michael Sutton) and Robin Scorpio (Kimberly McCullough). After a struggle that lasted throughout most of 1995, Stone dies from AIDS at the age of 19 and his death is followed by 17-year-old Robin having to deal with being HIV-positive as a result of their relationship. Sutton received a nomination for the Daytime Emmy Award for Outstanding Supporting Actor in a Drama Series and McCullough won an Daytime Emmy Award for Outstanding Younger Actress in a Drama Series award. ABC featured an Afterschool Special "Positive: A Journey Into AIDS" revolving around the AIDS story as well as The New York Times best selling novel Robin's Diary.
