Incidence and risk factors in sudden unexpected death in epilepsy: a prospective cohort study.
2001
Objective: To determine incidence of and risk factors for sudden unexpected death in epilepsy (SUDEP). Methods: Three epilepsy centers enrolled 4,578 patients and prospectively followed these patients for 16,463 patient-years. The cohort was screened for death annually. Deaths were investigated to determine whether SUDEP occurred. Potential risk factors were compared in SUDEP cases and in controls enrolled contemporaneously at the same center. Results: Incidence of SUDEP was 1.21/1,000 patient-years and was higher among women (1.45/1,000) than men (0.98/1,000). SUDEP accounted for 18% of all deaths. Occurrence of tonic-clonic seizures, treatment with more than two anticonvulsant medications…
TMS activation of interhemispheric pathways between the posterior parietal cortex and the contralateral motor cortex
2016
Using a twin coil transcranial magnetic stimulation (tc-TMS) approach we have previously demonstrated that facilitation may be detected in the primary motor cortex (M1) following stimulation over the ipsilateral caudal intraparietal sulcus (cIPS). Here we tested the interhemispheric interactions between the IPS and the contralateral motor cortex (M1). We found that conditioning the right cIPS facilitated contralateral M1 when the conditioning stimulus had an intensity of 90% resting motor threshold (RMT) but not at 70% or 110% RMT. Facilitation was maximal when the interstimulus interval (ISI) between cIPS and M1 was 6 or 12 ms. These facilitatory effects were mediated by interactions with …
The PACE study: Past-year prevalence of migraine in Parma's adult general population
2012
Background: In the literature there are few data about the prevalence of primary headaches, including migraine, in the Italian general population. The PACE study (PArma CEfalea, or ‘Headache in Parma’) is an observational study aimed at detecting the prevalence and clinical features of primary headaches in the city of Parma’s adult general population. Materials and methods: A total of 904 subjects representative of Parma’s adult general population were interviewed face-to-face by a physician from the Parma Headache Centre. They were given a specially designed and validated questionnaire for the diagnosis of primary headaches according to the ICHD-II criteria. Results: Past-year adjusted pr…
Identification of Biomarkers in Cerebrospinal Fluid and Serum of Multiple Sclerosis Patients by Immunoproteomics Approach
2014
Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating disease of the central nervous system. At present, the molecular mechanisms causing the initiation, development and progression of MS are poorly understood, and no reliable proteinaceous disease markers are available. In this study, we used an immunoproteomics approach to identify autoreactive antibodies in the cerebrospinal fluid of MS patients to use as candidate markers with potential diagnostic value. We identified an autoreactive anti-transferrin antibody that may have a potential link with the development and progression of MS. We found this antibody at high levels also in the serum of MS patients and created an immun…
The prevalence of sleep impairments and predictors of sleep quality among patients with asthma
2020
Background: Sleep is a significant dimension of daily life. However, only a few studies have examined the sleep quality of asthmatics in a real-world clinical settings. Objective: This study is aimed to estimate the prevalence of sleep impairments among asthmatic patients and examine the relationship between sleep quality, asthma control, rhinitis symptoms, and sociodemographic characteristics. Methods: The present study adopted the observational cross-sectional research design that has been designed by the Italian Respiratory Society and used valid assessments to measure the study variables. Results: Data from 1150 asthmatic patients (mean age 51.01 years ± 16.03) were subjected to analysi…
Quality of life, depression and fatigue in mildly disabled patients with relapsing–remitting multiple sclerosis receiving subcutaneous interferon bet…
2011
Background: The precise relationships among quality of life, depression, fatigue and cognitive impairment in multiple sclerosis (MS) are complex and poorly understood. Objective: To assess the effects of subcutaneous interferon beta-1a on quality of life, depression and fatigue over 3 years in the COGIMUS study, and to examine the relationship between these outcomes and baseline cognitive status. Methods: COGIMUS was an observational 3-year trial assessing cognitive function in 459 patients with relapsing–remitting MS treated with subcutaneous interferon beta-1a. Results: In total, 331 patients completed the study (168 received interferon beta-1a, 44 µg subcutaneously three times weekly, a…
Health-related quality of life in epilepsy: findings obtained with a new Italian instrument
2008
The aim of the present study was to evaluate the Epi-QoL, a new Italian-specific measure of health-related quality of life (HRQOL) for adults with epilepsy; the clinical variables that affected the HRQOL score were also assessed. The Epi-QoL is a 46-item self-administered questionnaire focusing on six domains: Physical Functioning, Cognitive Functioning, Emotional Well-Being, Social Functioning, Seizure Worry, and Medication Effects. Eight hundred fifteen patients recruited from 24 secondary and tertiary Italian centers for the care of epilepsy were assessed. The results supported the reliability and validity of the Epi-QoL as a measure of HRQOL. The variables that significantly affected HR…
Migraine and Sport in a Physically Active Population of Students: Results of a Cross‐Sectional Study
2020
Abstract Objective: In this study, we explored the relationship between migraine and sport in a physically active population of students, analyzing the risk of migraine among sporty students. Background: The relationship between sport and migraine is controversial; moreover, several studies report on sport as a migraine trigger, but there is evidence that physical activity could have a relevant role in migraine prevention. Methods: A cross-sectional survey was conducted using the validated ID-migraine questionnaire including specific demo-anthropometric (gender, age, weight, height) and sports variables on a potentially active student population of the University of Palermo. Evaluation in p…
Migraine mediates the influence of C677T MTHFR genotypes on ischemic stroke risk with a stroke-subtype effect.
2007
Background and Purpose— The objective was to investigate the role of C677T MTHFR polymorphism in migraine pathogenesis and in the migraine–ischemic stroke pathway. Methods— A first genotype–migraine association study was conducted on 100 patients with migraine with aura (MA), 106 with migraine without aura (MO), and 105 subjects without migraine, which provided evidence in favor of association of the TT677 MTHFR genotype with increased risk of MA compared with both control subjects (OR, 2.48; 95% CI, 1.11 to 5.58) and patients with MO (OR, 2.21; 95% CI, 1.01 to 4.82). Based on these findings, mediational models of the genotype–migraine–stroke pathway were fitted on a group of 106 patients …
The HLA locus and multiple sclerosis in Sicily
2005
The authors report the analysis of HLA-class II allelic heterogeneity in a well characterized multiple sclerosis (MS) Sicilian dataset. Family-based association analysis revealed evidence for excess transmission to affected individuals for alleles HLA-DRB1*1501, DRB1*04, and DQB1*0302. When analyzed as haplotypes, the authors observed excess transmission for the DRB1*0400-DQB1*0302 haplotype. Sicilian patients share the HLA-DRB1*1501 susceptibility allele with affecteds living in continental Italy, but also display the allelic heterogeneity that characterizes Mediterranean populations.
