A comparison of various guidelines and strategies for treatment of sore throat provides information that may help optimize use of diagnostic tests and reduce unnecessary use of antibiotics, according to a study in the April 7 issue of The Journal of the American Medical Association (JAMA).
According to background information in the article, recent guidelines for management of a sore throat (pharyngitis) vary in their recommendations concerning antibiotic treatment and the need for laboratory confirmation of group A streptococcus (GAS, "strep throat"). An estimated 6.7 million health care visits are made by adults with a sore throat in the United States annually; between 1989 and 1999, 70 percent of adults presenting with sore throat received an antibiotic prescription.
Warren McIsaac, M.D., M.Sc., of Mount Sinai Hospital, Toronto, Ontario, and colleagues conducted a study to assess the impact of different clinical guidelines on the appropriateness of antibiotics prescribed, the proportion of GAS sore throat cases identified, and the use of throat cultures and rapid tests to detect GAS in a population of children and adults with a chief complaint of a sore throat.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
