Listen to the BBC Case Notes program which reviews a different medical condition every week. Last October, the topic of the 30-minute radio program was allergies:
"Up to a third of the population will suffer from an allergy at some point in their lives. In this edition of Case Notes Dr Mark Porter asks why there has been such an apparent explosion in allergies in recent years."
