Alexandria, Va. - The American Academy of Otolaryngology – Head and Neck Surgery Foundation (AAO-HNSF) will issue the first comprehensive clinical guidelines to help health care practitioners identify patients with cerumen (commonly referred to as earwax) impaction. The guidelines emphasize evidence-based management of cerumen impaction by clinicians, and inform patients of the purpose of ear wax in hearing health.
PHILADELPHIA – Radiation from the atomic bomb blasts in Hiroshima and Nagasaki, Japan, in 1945, likely rearranged chromosomes in some survivors who later developed papillary thyroid cancer as adults, according to Japanese researchers.
Scientists based in Switzerland and South Africa have created a biophysical methodology that may help to overcome hearing deficits, and potentially remedy even substantial hearing loss. The authors propose a method of retuning functioning regions of the ear to recognize frequencies originally associated with damaged areas. Details are published August 29th in the open-access journal PLoS Computational Biology.
All drugs used to treat psychosis are linked to an increased risk of stroke, and dementia sufferers are at double the risk, according to a study published on bmj.com today.
Previous research has shown that second generation (atypical) antipsychotic drugs can increase the chances of patients having a stroke. But the risk of stroke associated with first generation (typical) antipsychotics, and whether the risk differs in people with and without dementia, is not known.
Last week the government in England closed its consultation on the effectiveness of vascular checks for high-risk individuals aged 40-74, to be rolled out in 2009-10, but will this strategy be worthwhile? Experts debate the issue on bmj.com today.
The Department of Health suggests that up to 9 500 heart attacks and strokes and 2 000 deaths could be prevented each year by vascular screening and managing high-risk individuals aged 40-74 in England.
Des Moines, Iowa – August 27, 2008 – What happens when linguistic tools used to analyze human language are applied to a conversation between a language-competent bonobo and a human? The findings, published this month in the Journal of Integrative Psychological and Behavioral Science, indicate that bonobos may exhibit larger linguistic competency in ordinary conversation than in controlled experimental settings.
Shedding some genetically induced excess baggage may have helped a tiny fish thrive in freshwater and outsize its marine ancestors, according to a UBC study published today in Science Express.
Measuring three to 10 centimetres long, stickleback fish originated in the ocean but began populating freshwater lakes and streams following the last ice age. Over the past 20,000 years - a relatively short time span in evolutionary terms - freshwater sticklebacks have lost their bony lateral plates, or "armour," in these new environments.
GAINESVILLE, Fla. --- They aren't the lost cities early explorers sought fruitlessly to discover.
But ancient settlements in the Amazon, now almost entirely obscured by tropical forest, were once large and complex enough to be considered "urban" as the term is commonly applied to both medieval European and ancient Greek communities.
Waltham, MA—Everybody loves the way breakfast eggs conveniently slide off of Teflon without leaving any pesky pieces of egg in the pan. Indeed, the carbon-fluorine bond at the heart of Teflon cookware is so helpful we also use it in clothing, lubricants, refrigerants, anesthetics, semiconductors, and even blood substitutes. But the very strength of the C-F bond that makes it useful in so many applications also gives it formidable greenhouse gas effects that persist in nature.
