INDIANAPOLIS -- A new device can detect acid reflux in the esophagus without putting a catheter down the nose and throat, Staying Healthy's Stacia Matthews reported.

The gelcap-size device, called Bravo, is inserted into a patient's esophagus. It transmits the patient's acid levels to a pager-size computer that the patient wears for 24 hours.

The insertion is painless, said Dr. Jon Maier of St. John's Health System in Indiana.

"They don't even know it's there," Maier said. "They can swallow and eat and we get our information -- which is improved -- and consequently determine what's best for them."

The device passes naturally through the patient's digestive tract.

Researchers Seek Women For Bone-Drug Study

Doctors at the Indiana University School of Medicine are looking for women with osteoporosis to help them test a drug designed to build bone density.

The drug, zoledronic acid, is given once a year through an IV. The treatment takes 15 minutes.

Previous studies have shown the drug builds bone density.

The study subjects must be between 65 and 89.
