The MammoSite system is among the thousands of devices the F.D.A. lets onto the market each year after only cursory review and with no clear evidence that they help patients. Doctors are free to use those products as they see fit, without telling patients that the devices are not proved. And because the doctors are frequently paid more by Medicare as a way to compensate them for the extra time and expense of adopting new procedures, these unproven products can become widely adopted.
Independent health researcher Grace Filby, who won a Churchill Fellowship for her research into phage therapy, is calling on the government for more research into the possible side-effects of the HPV vaccine that is currently being given to teenage girls.
Filby believes that not enough is known about the effects of the vaccine on children with pre-existing medical conditions and weakened immune systems. She says, "We simply do not know whether the vaccine interacts with other medication or medical conditions, and the manufacturers have not studied it yet. This could be a very valid reason why some families and schools might hesitate or opt out."
What is the average life expectancy of Americans? For a long time it has been the low seventies for men and upper seventies for women. So it comes as a shock to learn that the average life expectancy for Americans has dropped to 69.3 years, according to the America's Health Rankings report, issued at the American Public Health Association's annual meeting.
The scientific study that found "radiation is the only known cause of breast cancer in mice" was conducted at the Lawrence Berkeley National Laboratory, home of the Manhattan Project -- the World War II atomic bomb development project which produced the Hiroshima and Nagasaki atomic bombs -- and where they have been studying the biological/environmental effects of radiation for 68 years. After billions of dollars in research funds, however, they could never identify the cause of breast cancer in women.
Half of all American doctors responding to a nationwide survey say they regularly prescribe placebos to patients. The results trouble medical ethicists, who say more research is needed to determine whether doctors must deceive patients in order for placebos to work.
The most common placebos the American doctors reported using were headache pills and vitamins, but a significant number also reported prescribing antibiotics and sedatives
Scientists have made a dramatic leap forward in the treatment of multiple sclerosis with the discovery of a drug that not only halts the disease but can also reverse it.
The discovery is being hailed as the biggest advance against the debilitating neurological condition for more than a decade and could prove effective against other, similar diseases. The MS Society said it was "delighted" by the results.
