(CHICAGO TRIBUNE) — NEW YORK— Casey Kasem, host of the “American Top 40″ countdown for four decades, remained in critical condition at a Washington state hospital on Sunday and was being treated for an infected bedsore, a hospital spokesman said.

Kasem, who was also the voice of Shaggy in the “Scooby-Doo” cartoons and one of the most recognisable voices on American radio, was admitted to St Anthony Hospital in Gig Harbor last week.

The 82-year-old former DJ has been alert throughout his hospitalisation, receiving wound care, intravenous antibiotic therapy, blood pressure support medication and treatment for his pain, hospital spokesman Scott Thompson said.
