Some previous case-control studies reported a positive or weakly positive association between lung cancers risk and residential radon concentrations, while some found no evidence of an association. The North American pooling study was made to assess the seemingly disparate findings from these earlier research. Field and Lynch were part of a global team of researchers who performed the mixed analysis of the original residential radon research, executed in Connecticut, Iowa, NJ, Missouri, and Utah and South Idaho, and also Winnipeg, Canada. The initial studies were funded from several federal sources, including the National Institute of Environmental Health Sciences and the National Malignancy Institute. The investigators’ overview of 3,662 cases and 4,966 controls from these combined research represents the largest analytic radon epidemiologic study ever performed in THE UNITED STATES.Analysis supports use of temporal lobe resection to treat medication-resistant epilepsy Persons with temporal lobe epilepsy who all do not react to medication could get a substantial gain in life expectancy and standard of living by undergoing medical procedures of the temporal lobe section of the brain, according to an evaluation reported in the December 3 issue of JAMA, the Journal of the American Medical Association. Despite available anti-epileptic drugs, 20 % to 40 % of most patients with epilepsy do not respond to medical management. Temporal lobe epilepsy may be the most common form of epilepsy and the most likely to be medically non-responsive, and these sufferers are at increased risk of premature loss of life, according to background details in the article.
