American men with cancer more likely to die than women

LOS ANGELES (Reuters) - Men who are diagnosed with cancer are more likely to die from the disease than women, due to a higher initial risk and later detection, U.S. government research showed. The National Cancer Institute study looked at a database of 36 different types of cancer from 1977 to 2006.

Trial size may limit use of Seattle Genetics drug

WASHINGTON (Reuters) - U.S. drug reviewers might limit the use of a Seattle Genetics Inc experimental blood cancer drug due to the narrow scope of its clinical trials, sending the company's shares down 3.6 percent. In documents released on Tuesday the Food and Drug Administration asked an advisory panel to consider the drug, under the proposed trade name Adcetris, for use in previously treated patients with Hodgkin's lymphoma and anaplastic large cell lymphoma (ALCL). About 9,000 Americans a year are diagnosed with Hodgkin's lymphoma and 3,000 with ALCL.

FDA proposes targeted drug testing guidelines

WASHINGTON (Reuters) - Targeted drugs or therapies up for regulatory approval would have to be reviewed simultaneously with the diagnostic devices they rely on, according to a proposed policy issued on Tuesday. So-called targeted treatments or personalized medicines are tailored to a person's genetic makeup and are being increasingly developed by drug companies.

Kids respond better to early "lazy eye" treatment

NEW YORK (Reuters Health) - Treating "lazy eye" is more likely to be successful the younger the child, but even older kids can benefit more than was previously believed, according to a large new study. Researchers reviewed data on nearly 1,000 children treated for amblyopia, or lazy eye -- diminished vision in one eye that can stem from a number of causes. They found that kids between the ages of three and seven were much more responsive to treatment than kids between seven and 13, especially in moderate to severe cases.

More kids see dentists when Medicaid rates rise

NEW YORK (Reuters Health) - Higher payments to dentists who treat kids on Medicaid translate into more of those kids getting regular teeth cleaning, according to a new study. While that's positive news for some states that have upped reimbursement rates over the last decade, researchers worry that budget cuts might put kids' access to dental care in jeopardy.

Experts grow whole tooth units using mouse stem cells

HONG KONG (Reuters) - Scientists in Japan said on Wednesday they have created teeth -- complete with connective fibers and bones -- by using mouse stem cells and successfully transplanted them into mice, a step they hope will lead to progress in stem cell research. The entire tooth units, which were inserted into lower jaws of mice, attached successfully with jaw bones and the rats were able to chew normally, the researchers wrote in a paper in PLoS One (Public Library of Science).

Placebo effect seen in treating colds

NEW YORK (Reuters Health) - People who believe a cold remedy will work may indeed feel better sooner -- even if they don't get the real treatment, a new study suggests. Researchers say their findings are evidence that the so-called placebo effect is at work in recovery from the common cold.
