Taking parathyroid hormone followed by a year on alendronate shows strong osteoporosis benefit

Postmenopausal women who took a bone-building drug for one year followed by a year on a standard drug that fights bone loss experienced greater increases in bone density than has been reported from any other drug regimen, an NIH-sponsored study has found. Bone density is the standard predictor of fracture risk associated with osteoporosis.

Combined computed tomography (CT) and positron emission tomography (PET) - may detect the spread of head and neck cancer more accurately

"PET/CT is very helpful in determining where we should pinpoint our biopsies for recurrent disease," said Dr. Carol Shores, assistant professor of otolaryngology/head and neck surgery at UNC and the report's senior author. Shores is a member of the UNC Lineberger Comprehensive Cancer Center.
