EDMONTON - Alberta doctors are being told there isn't a lot of information on how to provide followup care for multiple sclerosis patients who have undergone an unproven procedure outside the country. A document written by a committee of doctors and circulated by the province's College of Physicians and Surgeons says there's little research on how to treat people who have undergone the controversial liberation therapy. "There's situations where it's not going to be really clear as to what the followup specifically should be or the treatment should be," said college registrar Trevor Theman.
