Sick List: Richard Pryor is back in a Brisbane, Australia, hospital. Pryor, 49, was discharged Sunday and had been planning to fly home to Los Angeles but he was readmitted Tuesday after experiencing further problems. Pryor was vacationing on Australia’s Gold Coast last week when he suffered a heart attack. A hospital spokeswoman said Pryor was in stable and satisfactory condition. . . . Singer Gloria Estefan’s recovery from a broken back is going so well that she may be released from a New York hospital this weekend.
