Using data drawn from queries entered into Google, Microsoft and Yahoo search engines, scientists at Microsoft, Stanford and Columbia University have for the first time been able to detect evidence of unreported prescription drug side effects before they were found by the Food and Drug Administration’s warning system.
Using automated software tools to examine queries by six million Internet users taken from Web search logs in 2010, the researchers looked for searches relating to an antidepressant, paroxetine, and a cholesterol lowering drug, pravastatin. They were able to find evidence that the combination of the two drugs caused high blood sugar.
The study, which was reported in the Journal of the American Medical Informatics Association on Wednesday, is based on data-mining techniques similar to those employed by services like Google Flu Trends, which has been used to give early warning of the prevalence of the sickness to the public.

For medieval physicians, the mnemic apparatus of choice was what is sometimes today known as a folding almanac or a belt book. There are thought to be just 29 such almanacs that have survived to the present day.
The almanacs contained detailed astrological calendars, lunar tables, diagrams of the human body and so on necessary for the practice of lunar medicine during the 14th and 15th centuries. They were small and strung onto a cord that attached to a physcian’s girdle or belt.

Ultra-thin electronics that dissolve inside the body have been devised by scientists in the US and could be used for a range of medical roles.
The devices can “melt away” once their job is done, according to research published in the journal Science.
The technology has already been used to heat a wound to keep it free from infection by bacteria.
The components are made of silicon and magnesium oxide, and placed in a protective layer of silk.

A laser device for less painful injections has been developed by South Korean scientists.
The system could replace traditional needles, with a jab as painless as being hit with a puff of air.
The laser is already used in aesthetic skin treatments. The aim now is to make low-cost injectors for clinical use.

If you’re not afraid to swallow your technology, you may want to check out new tech cleared by the Food and Drug Administration this week that lets you ingest a digital sensor powered by stomach acid that alerts your doctors about your health and your treatment habits.
The technology consists of a tiny, silicon-based sensor that, at 1mm wide (roughly the size of a grain of sand), can be consumed via pills and pharmaceuticals and pass through the body much like high-fiber food.
According to the developer, Proteus Digital Health, once the sensor is swallowed, stomach fluids that come into contact with it provide enough power to relay a signal that documents exactly when it was taken. This data is transmitted to a battery-powered patch worn on the skin that detects the signal and records the exact time the sensor was swallowed.
