Rates of breast biopsy (removal of tissue for diagnostic evaluation) remained stable over a 12 year period even as mammogram use increased and new and less invasive biopsy techniques were introduced, according to a study in the July 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Changes in the guidelines for breast cancer screening have resulted in increased use of mammography. However, some women screened by mammography may have a false positive result, requiring further tests, including biopsy, resulting in anxiety, inconveniences and trauma for the patient as well as increased costs, according to background information in the article. Further, the authors suggest, the advent of less invasive breast biopsy techniques might also contribute to an increase in the use of biopsy, but there is little information on the actual frequency of biopsy in the general community.
Karthik Ghosh, M.D., M.S., of the Mayo Clinic, Rochester, Minn., and colleagues, reviewed the medical records of women 18 years and older from January 1, 1988 through December 31, 1999, using the resources of the Rochester Epidemiology Project which indexes all inpatient and outpatient medical care provided to residents of Olmsted County, Minn. The rate of utilization of biopsy was calculated as the number of biopsies performed (except when multiple biopsies were performed on the same breast at one time) compared with the number of women in Olmsted County.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
