While cervical disc pathology can unquestionably produce radiculopathy, many patients presenting with arm pain, paresthesia or perceived weakness do not exhibit the clinical behavior of true nerve-root compromise. In these cases, failure to differentiate the primary pain generator may lead to unnecessary spinal injections, nerve ablation procedures or surgical consultation despite limited likelihood of benefit.
Online Advertising Works
Over the past few years businesses have bemoaned the that they have recouped little if any of the money they spend advertising on the Internet. However, a just released survey by the Emerging Technologies Research Group shows that online advertising can indeed be effective, and that people are buying products as a result of ads displayed online.
The survey was conducted between February and April, 1997. Of those who are currently using the Internet, 27% said they had made an online purchase in the past 12 months. Thirty-nine percent of those purchasers bought a product or service after clicking on an advertisement. Overall, 36% of all Internet users have clicked on an online ad.
Estimates show that there are roughly 31 million American adults on the Internet. Given the above survey figures, that would equate to roughly 8.5 million Americans who purchased something over the Internet in the past year.
