Aβ is the main component of amyloid deposits in Alzheimer disease (AD) and its aggregation into oligomers, protofibrils and fibrils is considered a seminal event in the pathogenesis of AD. Aβ with C-terminus at residue 42 is the most abundant species in parenchymal deposits, whereas Aβ with C-terminus at residue 40 predominates in the amyloid of the walls(More)
In Creutzfeldt-Jakob disease (CJD), molecular typing based on the size of the protease resistant core of the disease-associated prion protein (PrP(Sc) ) and the M/V polymorphism at codon 129 of the PRNP gene correlates with the clinico-pathologic subtypes. Approximately 95% of the sporadic 129MM CJD patients are characterized by cerebral deposition of type(More)
We have studied 122 patients (52 men and 70 women) with definite Multiple Sclerosis (MS) to evaluate the frequency and clinical characteristics of pain in MS. The Hamilton Rating Scale for depression, the Beck-Self Depression Inventory and the Kurtzke Disability Status Scale were used in all patients. We have divided the patients with pain in two groups:(More)
We evaluated the effect of 25 mg bid amitriptyline on muscle contraction headache in 36 patients with Parkinson's disease in a randomized double-blind placebo-controlled study. Treatment lasted 12 weeks, and we assessed the efficacy by number of days with headache, sum-of-severity score (intensity X number of days with headache), and consumption of(More)
The relation between depression and epilepsy was evaluated in 96 epileptic out-patients. We found that 50% of epileptic patients fulfilled the DSM-IIIR criteria for depression. The Hamilton Rating Scale for Depression, the Beck Self Depression Inventory and the Zung Anxiety Scale were also used in all patients. The patients with partial seizures with(More)
Cerebrospinal fluid (CSF) and serum concentrations of beta-2-microglobulin (beta-2-m) were evaluated in 19 patients with clinically definite multiple sclerosis (MS), in 21 with AIDS dementia complex (ADC), and in 20 subjects with other neurological diseases (OND). CSF beta-2-m and CSF/serum beta-2-m ratio were significantly higher in the patients with ADC(More)
Depression is a common psychiatric problem associated with epilepsy. Interictal depressive symptoms are more frequent and severe in epileptic patients than in subjects with comparable chronic neurologic diseases or physical handicaps. Epileptic depression was characterized as major or dysthymic: bipolar depression is rarely described. Several Authors are of(More)
Clinicomorphological features of 11 cases of non-crescentic acute post-streptococcal glomerulonephritis (APSGN) were reviewed. Intraglomerular and interstitial leukocytes and their possible correlation with the adhesion molecules intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and endothelial-leukocyte adhesion(More)
BACKGROUND Among our cases of IgA glomerulonephritis (IgAGN), 10% show necrotizing/extracapillary lesions involving a small percentage of glomeruli and associated with a certain degree of inflammation in absence of glomerular and interstitial scarring. In our experience, also in repeat biopsies, these cases of IgAGN have a worse prognosis probably because(More)
A trial was performed on thirty-two patients with cerebrovascular disease (transient ischaemic attack and stroke) to assess the effect of ticlopidine, a new inhibitor of platelet aggregation, on some platelet functions and coagulation, and its safety in long-term use (6 months). The results show that ticlopidine was highly effective in inhibiting(More)
