We applied repetitive transcranial magnetic stimulation (rTMS) in order to induce interference on visuo-spatial perception in 11 healthy subjects. Subjects performed a visuo-spatial task requiring judgements about the symmetry of prebisected lines. Visual stimuli consisted of symmetrically or asymmetrically transected lines, tachystoscopically presented for(More)
To verify the role of interhemispheric influences on manifestations of neglect, the authors investigated the effects of a transient repetitive transcranial magnetic stimulation (rTMS)-induced disruption of the unaffected hemisphere on contralesional visuospatial neglect in two left- and five right-brain-damaged patients. Parietal rTMS of the unaffected(More)
OBJECTIVE To investigate the association between cigarette smoking, alcohol drinking, coffee consumption and Parkinson's disease (PD). METHODS We selected subjects affected by idiopathic PD, with a Mini-Mental State Examination of > or =24, and controls matched 1 to 1 with cases by age (+/- 2 years) and sex. Controls were randomly selected from the(More)
OBJECTIVE To compare the monthly distribution of multiple sclerosis (MS) patients' births with that of the Sicilian population. BACKGROUND Studies on the association between season of birth and risk of MS are scanty and controversial. DESIGN AND METHODS Archives of the Institute of Neuropsychiatry of the Universities of Palermo and Catania were searched(More)
OBJECTIVE To investigate frequency and associated factors of post polio syndrome (PPS) in an Italian cohort of people with prior poliomyelitis. METHODS We screened subjects admitted for poliomyelitis at the paediatric hospital of the University of Palermo during the time frame 1945-1960. Patients who developed PPS were identified through a structured(More)
A neurophysiological (SEP, VEP) follow-up study was carried out in 30 diabetic patients with type I diabetes mellitus of ten or more years duration. This in order to investigate whether one year of improved glucoregulation may influence the progression of central damage. In our series, patients showed a significant decrement of HbA1C levels (p < 0.05) in(More)
To evaluate central nervous system involvement in diabetes, somatosensory (SEPs) and visual (VEPs) evoked potentials were investigated in a group of 35 patients and 20 sex, age-matched controls. In order to avoid methodological biases due to different type and duration of disease, we studied an omogeneous group of young insulin-dependent diabetics with ten(More)
BACKGROUND There are only 2 small sample studies investigating allodynia in the pediatric population. The aim of this study was to evaluate the frequency of allodynia during cephalalgic attacks in a juvenile population with primary headaches and its association with other symptoms of migraine. METHODS We reviewed all medical records of patients with(More)
This report is concerned with advances in the study of common senile brain degeneration and of its relationship with degenerative diseases of the brain in senility and pre-senility. In 1968, the principal topic of discussion at the 52nd Congress of the German Society of Pathology in Wiirzburg was the study of the senile brain, and presentations included(More)
The effect of some short-chain fatty acids (SCFA) produced by anaerobic bacteria, namely acetic, propionic, isobutyric, butyric, isovaleric and succinic acids, on production of light and release of lysozyme by human neutrophils exposed to chemotactic peptide fMet-Leu-Phe was investigated. A short period of incubation of neutrophils with SCFA led to marked(More)
