A therapy that helps regenerate receding gum tissue seems to hold up over the long term—and may offer patients an alternative to more-extensive dental surgery, a small study finds.One option for treating severe gum disease is surgery to replace tissue

In children with sleep-related breathing disorders, removing the tonsils and adenoids—an operation called adenotonsillectomy—is apt to yield long-lasting improvements in sleep and behavior, doctors from Kansas City report.More than two years after a group of children with sleep-related breathing disorders

People with arthritis seem to have an elevated rate of depression, but the disorder goes untreated more often than not, a new study suggests.Researchers found that among more than 130,000 Canadians in a national health survey, those with arthritic conditions

Cedars-Sinai Medical Center) Cancer stem-like cells have been implicated in the genesis of a variety of malignant cancers. Research scientists at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute have isolated stem-like cells in benign (pituitary) tumors and used these "mother"

Ohio State University Medical Center) Researchers at the Ohio State University Comprehensive Cancer Center and Dana-Farber Cancer Institute have discovered how hormone-dependent prostate cancer advances to the incurable hormone-independent disease state. The study shows that in androgen-independent prostate cancer, androgen
