OBJECTIVES Primary biliary cirrhosis (PBC) patients frequently complain of fatigue and loss of memory. The aim of this study was to evaluate the mental performance and the neuropsychological assessment in patients with PBC. METHODS A case-control study was performed that included 36 PBC patients (34 female, two male, mean age 55 yrs, 11 with stage II, 16(More)
Retrospective data regarding 290 patients suffering from spontaneous aortic dissection between January 1976 and June 1987 are reported. Dissection was always documented by retrograde aortography and data were collected from 11 catheterization laboratories operating in North-East Italy. The results show that over a 12-year period there was an increase in(More)
Plasma selenium was determined in 92 elderly women: a marked decrease was observed from the age of 65 years. Se-status in 20 elderly women was explored by investigation of the effects of 30 days' Se-supplementation with enriched tablets (Selevit-E) 66 micrograms per day. Serial determination was performed for Se plasma, e-GSH-Px (glutathione peroxidase),(More)
This research approaches the issues of introducing ICTs (Information and Communication Technologies) into Small and Medium Enterprises, with the aim of finding some conditions that make the organizational context able to manage the change process needed to really get the potential benefits of these technologies. The final objective is to propose a(More)
BACKGROUND Reversibility of pulmonary hypertension in patients affected by mitral stenosis is still under question. METHODS We selected 80 patients (mean age 48 +/- 14) who underwent successful percutaneous mitral valvuloplasty (PMV) for hemodynamic significant mitral stenosis (area < 1.5 cm2) with pulmonary hypertension (mean artery pulmonary(More)
Postoperative 24-hour Holter monitoring was performed in 106 patients with atrioventricular septal defect in order to identify the incidence of atrial and ventricular arrhythmias. Of the patients, 72 had separate atrioventricular orifices, including 13 with a small ventricular component to the defect, and 34 patients had a common atrioventricular orifice.(More)
Alterations in cholesterol homeostasis are associated with Alzheimer's disease (AD). The role played by specific fractions of serum lipoproteins in modifying the risk of AD, and the interaction with APOE genotype has not yet been investigated. We studied serum lipoprotein profiles using a gradient-density ultracentrifugation method in a cohort of late-onset(More)
Visceral (intra-abdominal) obesity is associated with a cluster of cardiovascular risk factors that together promote macrovascular and microvascular disease. An atherogenic dyslipidemia, characterized by an increase in serum triglyceride-rich lipoproteins, a decrease in plasma levels of high-density lipoprotein cholesterol and increased prevalence of small,(More)
An evaluation of the results of the Brazilian experience in colorectal laparoscopic procedures in a multicenter prospective protocol done by the Brazilian Society of Colo-Proctology is presented. From December 1991 to August 1998, 1,161 patients (583 men and 578 women; mean age, 49.8 years), were operated on laparoscopically. Most of the procedures (40.5%)(More)
Atrial vectorcardiograms (vcg) were analysed in 23 patients with partial (n = 15) or complete (n = 8) forms of atrioventricular septal defect (AVSD). The rotation and the projection of the maximum left atrial vector (MLAV) on the frontal plane (FP) and on the horizontal plane (HP) were noted. To assess the possible influence of the degree of left-to-right(More)
