Jennifer Matthews: For nearly 80 years, Jeanette Ruday never had a problem with her sinuses. Then -- Jeanette Ruday: I started coughing, and I coughed and coughed and coughed. Jennifer Matthews: Doctors prescribed one medication after another -- often the wrong one. Jeanette Ruday: You can have your prescription filled, and then they call you and they say, 'We have to change it. It's not the correct drug for you.' Jennifer Matthews: These days, she only fills enough to get her by until test results come in. In the future, patients won't have that problem. Doctor Bill Hanson: Ultimately what we hope to have is a device that can determine whether or not what you have is sinusitis, and if so, what kind of sinusitis. Jennifer Matthews: The electronic nose is based on an ancient practice. Doctor Bill Hanson: Physicians going way, way back to the dawn of time used their noses to smell people's breath and urine and bodies and diagnose diseases. Jennifer Matthews: Similarly, the device smells exhaled gases. Sensors compare them to odors they're trained to recognize. Doctor Bill Hanson: You'd start therapies either earlier, which would be good, or you wouldn't start therapies that weren't warranted, Jennifer Matthews: A study on the nose for detecting pneumonia found clear distinctions between patients with the infection and those who were healthy. It may have taken trial and error to help her, but Jeanette is finally finding enough relief that she can enjoy her days with her husband Harry -- cough-free. This is Jennifer Matthews reporting.
