We report the clinical, pathological, and genetic findings of a case of MELAS syndrome. This was a man who died for metabolic failure at the age of 27 years. His familiar history was positive for hypoacusia and stroke. He was of short stature and presented mild mental retardation. Since the age of 21 he suffered from recurrent brain-ischemic lesions mainly(More)
Primary headaches are closely related to sleep. Modifications in the patterns of arousal during sleep have been reported in migraine, especially in the nights preceding a headache attack. We aimed at evaluating the pattern of arousal from sleep in a group of patients affected by sleep-related migraine. We enrolled 10 consecutive patients, three males and(More)
The habituation to sensory stimuli of different modalities is reduced in migraine patients. However, the habituation to pain has never been evaluated. Our aim was to assess the nociceptive pathway function and the habituation to experimental pain in patients with migraine. Scalp potentials were evoked by CO(2) laser stimulation (laser evoked potentials,(More)
The objectives of this paper are to evaluate the efficacy and tolerability of topiramate, given at the dose of 100 mg/day, in the prophylactic treatment of migraine. The hypothesis that migraine is the result of a condition of neuronal hyperexcitability and the quest for drugs that are able to limit the number of crises justifies the attempt to utilise the(More)
The main aim of this study was to confirm in an Italian population affected by tension-type headache (TTH) the good profile of safety and tolerability of the combination paracetamol 1,000 mg-caffeine 130 mg (PCF) observed in previous studies, by a comparison with naproxen sodium 550 mg (NAP) and placebo (PLA). A secondary objective was to assess the(More)
In lambs, acute and chronic communicating hydrocephalus has been created by merely increasing the amplitude of the intraventricular cerebrospinal fluid (CSF) pulsations, leaving the mean CSF pressure unchanged. The pathologic changes occurring in this type of hydrocephalus do not differ qualitatively from those observed in obstructive hydrocephalus. Beside(More)
Pediatric migraine is a disabling condition, which can cause a significant impact on quality of life. Currently, no drugs have been approved by the FDA for its preventive treatment. Our aim was to review the medical literature concerning the efficacy and tolerability of topiramate in the prophylactic treatment of migraine in children and adolescents. A(More)
The brains of 3 adult subjects suffering from normotensive hydrocephalus have been examined pathologically. The diagnosis of normotensive hydrocephalus was based on clinical symptoms, pneumoencephalography and isotope cisternography, in 1 case integrated with the results of the constant-infusion manometric test. Part of the neuropathological findings were(More)
In this work we have developed and characterized primary cultures of neonatal rat trigeminal ganglia neurones; calcitonin-gene-related-peptide (CGRP) released from cells was taken as a marker of neuronal function. A significant and consistent increase in CGRP secretion was elicited by non-specific (56 mm KCl or veratridine) or specific (capsaicin)(More)
We report clinical, electrophysiological, magnetic resonance imaging, and nerve biopsy findings of 2 patients with definite multiple sclerosis and peripheral demyelinating disease. Although it is not easy to assess the real incidence of peripheral neuropathy in patients with multiple sclerosis, this association seems to be rare. The combination of central(More)
