Worldwide investigation of the epidemiology of epilepsy has suggested wide variations in the frequency of convulsive disorders. However, descriptive studies in general populations cannot be completely comparable because of a remarkable methodological dishomogeneity in definition of epilepsy, classification of seizures, and ascertainment, collection, and(More)
On the basis of previous epidemiologic studies, Parkinson disease was thought to be evenly distributed throughout the world. These studies, however, were conducted only on North European populations. The position with regard to the Mediterranean peoples was still unknown, and we therefore studied the frequency of Parkinson disease on the island of Sardinia,(More)
Numerous studies reported in recent years have shown that withdrawal from chronic consumption of drugs induces high levels of anxiety, both in humans and in animal models. In the present study, we demonstrated that withdrawal from chronic consumption of either ethanol or heroin causes a significant increase in plasma nerve growth factor, suggesting that the(More)
Hashimoto's encephalopathy and Creutzfeldt-Jakob disease (CJD) often have similar clinical features and may be confused, especially at onset. A 61-year-old woman developed rapidly progressive ataxia, myoclonus and dementia, with abnormalities seen on electroencephalography (EEG). Serum analysis disclosed high titers of antithyroid autoantibodies. Both(More)
BACKGROUND Intracranial haemorrhage (ICH) is a serious and potentially fatal complication of oral anticoagulant therapy (OAT). Prothrombin complex concentrates (PCCs) produce a rapid and effective reversal of OAT effects, but little evidence exists on their efficacy and safety in the management of ICH in patients on OAT. AIM To evaluate the efficacy and(More)
This investigation was conducted to clarify the epidemiology of ALS disease in Sardinia. During the years 1965-1974, the average annual incidence was found to be 0.64/100,000 inhabitants. On prevalence day, October 24th, 1974, the prevalence rate was 1.56/100,000 inhabitants. A significant male predominance was found, the average annual incidence rates for(More)
The comparative geography of multiple sclerosis (MS) and nonneurological diseases considered to be autoimmune is of great interest. But there are few appropriate investigations. Some have found an increase in the frequency of MS, rheumatoid arthritis and rheumatic heart disease depending on the geographic latitude. Nevertheless, the significance of the(More)
AIM To examine the dislocation resistance of three root canal sealers from radicular dentine with and without immersion in a simulated body fluid (SBF), using a modified push-out test design that produced simulated canal spaces of uniform dimensions under identical cleaning and shaping conditions.
