    Notes: Variant Creutzfeldt-Jakob disease (vCJD) is associated with extensive prion infection of lymphoreticular tissues during the prolonged asymptomatic incubation period. Instruments exposed to infected tissues of preclinically infected individuals during medical or surgical procedures represent a potential risk of iatrogenic transmission of vCJD prions. We assessed the frequency of contamination with lymphoid tissue of single-use laryngoscope blades used for tracheal intubation for general anaesthesia. Using a cyto-centrifugation technique, lymphocytes were detected from 30% of laryngoscope blades studied. As prions resist routine sterilisation procedures, the use of non-disposable laryngoscope blades poses a risk of transmitting vCJD from patient to patient. The use of such instruments should be abandoned and disposable alternatives used.

    Notes: Abstract Creutzfeldt-Jakob disease (CJD) is a transmissible neurodegenerative disorder characterized by the accumulation of aggregates of a cellular protein, PrP, in the brain. In both human and animals, genetic alterations to the gene encoding PrP (PRNP in human) modulate susceptiblity to CJD. The recent epidemic of bovine spongiform encephalopathy in the UK has raised the possibility of transmission from animal produce to humans. To provide a baseline against which to assess possible risk factors, we have determined the frequencies of predisposing mutations and allelic variants in PRNP and their relative contributions to disease. Systematic PRNP genotype analysis was performed on suspected CJD cases referred to the National Surveillance Unit in the UK over the period 1990–1993. Inspection of 120 candidate cases revealed 67 patients with definite and probable CJD, based on clinical and neuropathological criteria. No PRNP mutations were detected in any of the remaining 53 patients assessed as “non-CJD”. A disease-associated mutation in the PRNP gene was identified in nine (13.4%) definite and probable cases of CJD, a reliable estimate of the incidence of PRNP-related inherited CJD based on a prospective epidemiological series. Within the group of sporadic CJD patients (lacking PRNP mutations), we confirmed that the genotype distribution with respect to the common methionine/valine (Met/Val) polymorphism at codon 129 within PRNP was significantly different from the normal Caucasian population. The incidence of Met homozygosity at this site was more than doubled and correlated with increased susceptibility to the development of sporadic CJD. Unlike other recent studies, Val homozygosity was also confirmed to be a significant risk factor in sporadic CJD, with the relative risks for the three genotypes Met/Met:Val/Val:Met/Val being 11:4:1.
