Although he had never met her, Dr. William Marshall knew a lot about Paulette Schlander.
He knew that Schlander, who lives in Duluth, had gone to Africa on safari with her husband last fall.
He knew, too, that the 58-year-old dental assistant started experiencing strange muscle pains about a month later.
Now he was trying to figure out whether the two events were connected.
In the past, Marshall, an infectious disease expert at the Mayo Clinic, would have invited her to Rochester for a full exam. This time, he didn't have to.
For the past year, he and other Mayo physicians have been offering "virtual consults," or second opinions by e-mail, to a Duluth clinic, SuperiorHealth Center, where Schlander is a patient.
As part of a pilot project, Marshall and his colleagues have tried to solve dozens of medical puzzles, sight unseen, involving patients with cancer, diabetes, heart disease and other disorders. They rely almost entirely on records, images and lab tests to answer specific questions about diagnosis and treatment posed by the Duluth doctors.
So far, the numbers have been small. But some say it's a preview of things to come, as technology makes it easier than ever to render a medical opinion from a distance.
