The Food and Drug Administration has told the Laboratory Corporation of America that it is illegally marketing a blood test to detect ovarian cancer, according to a warning letter posted Wednesday on the F.D.A.’s Web site. The test, introduced in June, has raised hopes among women and their doctors because it promises to detect ovarian cancer at an early stage, when it is still treatable.
But some outside experts, including the Society of Gynecologic Oncologists, have said the test had not been proved accurate and might cause women to have unnecessary surgeries to remove their ovaries. The F.D.A. itself, in a previous letter to LabCorp, said the test “may harm the public health.”

'St John's Wort plant as effective as Prozac for treating depression', say scientists
It also had fewer side effects than many standard drugs used to help those battling despair.
Researchers compared the effects of the plant hypericum perforatum - popularly known as St John's Wort - with placebos or a wide range of old and new anti-depressants, including those from the new generation of SSRI drugs, such as Prozac and Seroxat.
The findings could prompt more GPs to prescribe St John's Wort.
In Germany, it is commonly given to children and teenagers.

Doctors: No hamsters or exotic pets for young kids
Warning: young children should not keep hedgehogs as pets - or hamsters, baby chicks, lizards and turtles, for that matter - because of risks for disease. That's according to the nation's leading pediatricians' group in a new report about dangers from exotic animals.
Besides evidence that they can carry dangerous and sometimes potentially deadly germs, exotic pets may be more prone than cats and dogs to bite, scratch or claw - putting children younger than 5 particularly at risk, the report says.
