Featuring a schoolboy who needed stitches after a bizarre joyride in an old lady's shopping trolley; a woodsman who ripped open his wrist with a machete; and a teenager who needed treatment after being terrorised by a terrier; and surgeons operating on a man after the metal plate on his collar bone popped out of his left shoulder. Plus, we meet the Norwegian adventurers who, on an Arctic expedition, were attacked in their sleep by a deadly polar bear.
