There is a wide variation in the use of laparoscopic surgery for gall bladder removal in Hong Kong hospitals, and use of this procedure is more likely at certain hospitals and among younger female patients operated on more recently, according to a study in the November issue of Archives of Surgery, one of the JAMA/Archives journals.
Laparoscopic cholecystectomy (LC, removal of the gallbladder by laparoscopy) is a well-established technique for the management of symptomatic gallstone disease. But acute cholecystitis (inflammation of the gallbladder) has been considered a relative, if not absolute, contraindication for LC because of the technical difficulties and a higher complication rate, according to background information in the article.
Chi Ming Lam, M.S., F.R.C.S., and colleagues with the Hospital Authority, Hong Kong, China, and the University of Hong Kong, investigated the variation in surgical treatment of acute cholecystitis in a stable population and the factors determining the use of LC in the emergency condition. They conducted a retrospective survey on 2,353 patients with pathologically proven acute cholecystitis who had gallbladder surgery at all public hospitals in Hong Kong from 1998 to 2002. The study reflected the practice of LC for acute cholecystitis in about 86 percent of the inpatient population in Hong Kong.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
