Intrathecal antibody production is a hallmark of multiple sclerosis and humoral immunity is thought to play an important role in the inflammatory response and development of demyelinated lesions. The presence of lymphoid follicle-like structures in the cerebral meninges of some multiple sclerosis patients indicates that B-cell maturation can be sustained(More)
A total of 10–15% of human transmissible spongiform encephalopathies (TSEs) or prion diseases are characterised by disease-specific mutations in the prion protein gene (PRNP). We examined the phenotype, distribution, and frequency of genetic TSEs (gTSEs) in different countries/geographical regions. We collected standardised data on gTSEs between 1993 and(More)
BACKGROUND An international study of the epidemiologic characteristics of Creutzfeldt-Jakob disease (CJD) was established in 1993 and included national registries in France, Germany, Italy, the Netherlands, Slovakia, and the United Kingdom. In 1997, the study was extended to Australia, Austria, Canada, Spain, and Switzerland. METHODS Data were pooled from(More)
AIM Remifentanil hydrochloride is an ultra-short acting m-opioid receptor agonist. This study compared the use of remifentanil with that of fentanyl during elective supratentorial craniotomy in a target controlled infusion (TCI)-propofol anesthesia regimen and evaluated the quality of recovery from anesthesia. METHODS After written informed consent for(More)
A collaborative study of human transmissible spongiform encephalopathies has been carried out from 1993 to 2000 and includes data from 10 national registries, the majority in Western Europe. In this study, we present analyses of predictors of survival in sporadic (n = 2304), iatrogenic (n = 106) and variant Creutzfeldt-Jakob disease (n = 86) and in cases(More)
The present study provides a characterization of the behavioral changes induced in preweaning mice by prenatal exposure to lamivudine (3TC), an antiviral drug recently entered in the clinical practice to treat HIV patients. Pregnant CD1 mice were given per os bidaily either 3TC at different doses (125, 250, or 500 mg/kg) or vehicle solution (saline 0.9%)(More)
OBJECTIVE To assess the incidence and mortality rates of genetic transmissible spongiform encephalopathy (TSE) diseases in Italy. METHODS The authors have sequenced the prion protein gene (PRNP) in 643 patients referred to the Italian Registry of Creutzfeldt-Jakob disease (CJD) and related disorders between 1993 and 2002. Crude age- and sex-specific(More)
BACKGROUND The role of high resolution pulsed and color Doppler ultrasound in the differential diagnosis of benign and malignant lymphadenopathy is still unclear. METHODS High resolution pulsed and color Doppler ultrasound was used prospectively to investigate superficial lymph node enlargement in 71 patients undergoing surgical biopsy at the onset of(More)
BACKGROUND Although epidemiological, clinical, and experimental evidence indicates that the inducible isoform of cyclo-oxygenase (COX-2) may be involved in the pathogenesis of several neurodegenerative disorders, the mechanisms whereby COX-2 contributes to Alzheimer's disease are largely unknown. OBJECTIVE To undertake a longitudinal study of CSF levels(More)
The levels of 2 arachidonic acid metabolites formed either by enzymatic activity of cyclooxygenase, i.e. prostaglandin E2 (PGE2), or by free radical-catalyzed peroxidation, i.e. F2-isoprostane 8-epi-prostaglandin F2alpha (8-epi-PGF2alpha), were measured in the CSF of subjects with sporadic and familial Creutzfeldt-Jakob disease (CJD) and in brain(More)
