Extractions: THE FUTURE IS NOW! Synopsis: In the media coverage of the British Mad Cow disease, the scientific community has been uncharacteristically quiet. This is partly because of the accidental transmission of the disease agent for the Creutzfeldt-Jacob Disease(CJD) to children in a major scientific experiment. But perhaps more important is the potential danger to scientists incomes from shifting public consciousness from genetic engineering to a new, non-nucleic acid disease agent, the prion. Not widely discussed is the similarity of the symptoms of CJD and Alzheimers disease which is not considered transmissible. But the chilling possibility is suggested by the fact that the research program of the prion discoverer has been funded as Alzheimers research for many years. Furthermore, drug companies are concerned that the disease may be transmitted in protein used as a base for cosmetics. Search the Web for prion +Pruisner and a months reading will appear on your screen. But why the Prusiner? Dr. Stanley B. Prusiner, M.D., is a professor of neurology and biochemistry at the University of California, San Francisco. He received the 1994 Albert Lasker Basic Medical Research Award for his discovery of the new class of disease-causing agents he named prions (pronounced pree-ons). The Lasker Award is the most prestigious medical research prize awarded in the United States.

I particularly like Venters' view that the rate of growth in the number of vCJD cases is much less than one would expect from a foodborne source. That, in fact, the rate of growth of these cases is "consistent with a previously misdiagnosed but extremely rare disease being found. This could have resulted from the improved ascertainment of all possible cases of Creutzfeldt-Jacob disease that has been achieved in recent years by the United Kingdom Creutzfeldt-Jacob Disease Surveillance Unit."

Extractions: Purpose: Creutzfeldt-Jacob diesase (CJD) is a rare dementing illness, characterized by a rapidly progressive dementia, ataxia and myoclonus. The diagnosis is often suspected on the basis of EEG and clinical findings. MR examinations can be helpful with hyperintens signal abnormalities in the basal ganglia being found on T2-WI images of patients with Creutzfeldt-Jakob diease. Materials and methods: We retrospectiwely reviewed the MR imaging findings of three patients (59-69) who had pathologically proved Creutzfeldt-Jacob disease and whose MR examination showed hyperintense signal in the basal ganglia on T2 weighted images. All imaging protocols included axial proton density and T2 weighted spin-echo (SE) sequences with a slice thickness of 6 mm. Conclusion: Creutzfeldt-Jakob disease is uniformly fatal, with a mean suvival time of 6 months to 1 year after diagnosis. The characteristic neuropathologic feature of CJD is spongiform encephalopathy, prominent depletion of neurons and astrocytes and marked gliosis are often seen. Bilateral hyperintense abnormalities on T2-weighted images of the basal ganglia can be seen in several disorders. We believe that bilaterally symmetric, diffuse hyperintens abnormalities in the basal ganglia on T2-weighted images of adults with a rapidly progressive dementia may be a specific sign of Creutzfeldt-Jacob disease.

Extractions: dlarson@uiuc.edu September 16, 2002 URBANA Recalls in children's car seats and toys, reports of product tampering and food contamination have created financial losses for individual companies, but other crises such as the threat of mad cow disease, can cripple an entire industry. Understanding what drives the behavior of consumers when faced with product-related crises like these was the topic of a recent study at the University of Illinois. A team of researchers in the College of Agricultural, Consumer and Environmental Sciences at U of I led by Joost M.E. Pennings, looked at how people respond to a risky situation. They chose to evaluate German, Dutch and American consumer reactions to the threat of mad cow disease. The researchers broke down risk behavior into two components: risk perceptions and risk attitudes. Risk perceptions are based on whether a person thinks it is likely that they might, for instance, contract a disease from eating beef their perception of the likelihood that something bad will happen to them. Risk attitude (or risk aversion ) reflects a consumer's general predisposition to the risk of contracting the disease and how willing they are to take a risk in the first place. "If beef consumption is primarily driven by risk perceptions that is, the likelihood of contracting a disease," said Pennings, "the solution to the mad cow crises would be to educate consumers about the level of risk they are taking." Pennings explained the flip side of the risk coin: If consumers' response to the mad cow crisis is driven by their risk attitudes, then the beef industry has fewer and costlier options, namely to test each cow for the disease and to slaughter those that test positive, hence ensuring that the risk is eliminated.

Extractions: Health Information from: Disease Injury ... Prevention Creutzfeldt-Jacob disease Definition: A brain disorder involving rapid decrease of mental function and movement abnormalities caused by damage to the tissues of the brain from a viral-like organism (a transmissible protein called a prion). Causes, incidence, and risk factors: Creutzfeldt-Jakob disease is an organic brain syndrome caused by a viral-type organism. The disorder is rare, occurring in about 1 out of 1,000,000 people. It usually first appears in midlife, beginning between ages 20 and 68, with the average age at onset of symptoms being between 57 and 62. Cases have occurred in adolescents who have received growth hormone derived from cadavers, despite the production process, which is intended to kill all bacterial and viral material in the product. The causative agent, or prion, is thought to have been transmitted in the growth hormone (extracted from the pituitary of cadavers), which explains the abnormally early appearance of the disease. Cadaver-derived growth hormone has been replaced by synthetically manufactured growth hormone and contagion is no longer a problem. Once symptoms appear there is rapid progression of the disorder with progressive loss of brain function. The lesion and deterioration of function is similar to that of

The reported accuracy rate can be as low as 50%. A.P. Georgiou and J.L. Cunningham ( Clin Biochem. 2001; 16:315-323) have used a vibrator to detect loosening of components. Engineers have long used vibration techniques to determine the integrity of laminated structures, eg, boat hulls. Excitation of a secure bone implant produces an output characteristic of a single unit having one resonant frequency and no harmonics, ie, the output wave is pure. After loosening or delaminaton of an implanted component, the separated elements respond to excitation differently. Appropriate instruments can demonstrate the differences. The authors used the diagnostic vibration technique on 23 patients admitted for revision total hip arthroplasty surgery and on 10 patients with recent and presumably secure implants. The technique was 100% accurate in its findings of hip implant loosening. Light at the End of the Tunnel Intensive keyboarding by computer users is a controversial cause of carpal tunnel syndrome. Much work time is lost from symptoms that are labeled carpal tunnel syndrome. There is a considerable cost for confirmatory nerve conduction studies, keyboard ergonomics are expensively applied, and the carpal ligament may be unnecessarily incised.

Extractions: Creutzfeldt-Jacob Disease (CJD) is a progressive, degenerative neurologic disorder with a clinically latent stage of up to 30 years. The duration from the onset of symptoms to death is 6 - 12 months. The symptoms include progressive ataxia, myoclonus, dementia with memory loss, vertigo, visual disturbances and EEG changes. The incidence of CJD in Canada is estimated at one case per million per year. The infectious agent is referred to as a prion, for proteinacious infectious particle. The prion is very resistant to regular decontamination and sterilization methods.CJD cases are presently classified as:a) Genetic: a familial form (5-15% of cases)b) Infectious: iatrogenic transmission: corneal transplants / dura mater grafts / pituitary hormones from CJD infected donors or inadequately sterilized CJD contaminated neurosurgical stereotactic electrodes ( <1% of cases).c) Sporadic: from an unknown source (90% of cases)Other prion diseases include Kuru, Gerstmann-Straussler-Scheinker disease (a genetic disease), Fatal Familial Insomnia (a genetic disease). Bovine Spongiform Encephalopathy (BSE) is a disease in cattle related to contaminated feed made from scrapie infected sheep and cattle. An outbreak of a variant of CJD (vCJD), thought to be related to the ingestion of BSE contaminated beef, was detected in 1997 in Europe. vCJD has a shorter incubation period, and presents in a younger population (
