Incidence of status epilepticus in southern Europe: a population study in the health district of Ferrara, Italy.
No full textBackground: Theepidemiologic features of status epilepticus (SE) are still in the course of definition. Methods: We carried out an intensive survey of multiple sources of case material in the resident population of the health district of Ferrara, Italy, in 2003. Information was collected on age, gender, duration, seizure type and etiology of SE. Results: The age- adjusted annual incidence rate of SE was 27.2/100,000 (95% CI = 19.4-36.9) and it was higher in men (41.7/100,000, 95% CI = 26.9-61.7) than in women (12.3/100,000, 95% CI = 6.9-20.4). The incidence was higher in the elderly (older than 60 years, 39.2/100,000) than in younger adults in the age group 20-59 years (14.7/100,000). The age-specific incidence showed a bimodal distribution peaking in the youngest (0-4 years) and in the oldest age group (75+ years). Cerebrovascular disease was the most frequent etiologic factor (45%). Epilepsy had previously been diagnosed in 40% of the patients. The case fatality was 5%. Conclusions: The study found a higher incidence of SE than that expected on the basis of the previous European studies suggesting that the risk of SE in southern Europe is higher and more similar to that estimated in population studies in the United States. The case fatality was lower than that reported in previous South-European population studies despite the similar clinical features of the patients. Indirect evidence suggests that several factors related to the SE management could have positively influenced the outcome
Epidemiology of Parkinson's disease in Italy. A descriptive survey in the U.S.L. of Cento, province of Ferrara, Emilia-Romagna.
No full textIn order to verify the epidemiology of Parkinson's disease in northern-Italy, we carried out a descriptive study in the Local Health Service No. 30 of Cento, Emilia-Romagna. Based on 73 accepted cases, the prevalence rate on December 31, 1987, was 190.3 per 100,000 population. No significant difference was reported between the two sexes. The highest rates were observed in the age groups over 60 years. Our data indicate that the risk of Parkinson's disease in northern-Italy is similar to that observed in other Caucasian population
Incidence of epilepsy in Ferrara, Italy.
No full textFew studies have been carried out in the same area at different times, allowing an assessment of the incidence of epilepsy (E.), including all ages, over time. The available data on temporal trend show a decrease in E. incidence in childhood and an increase in the elderly. We sought to update the incidence of E. in the province of Ferrara, where a previous study estimated an incidence rate of 33.1 per 100,000, 35.8, if standardized to the European population. Newly diagnosed patients aged up to 14 years were drawn from a community-based prospective multi-source registry, and adult onset E. cases were collected through multiple overlapping sources of case collection. Cases were included and classified according to ILAE recommendations. During the study period (2007-2008), 141 newly diagnosed cases (66 men and 75 women) living in the study area were identified. The crude incidence rate was 46.1 per 100,000 person-years (95 % CI 39.0-54.5), 35.5 (95 % CI 28.0-43.0) if adjusted to the European population. The incidence of childhood and adolescence epilepsy was 57.0 per 100,000 person-years (95 % CI 33.8-90.0), lower than that reported in our previous study, and it was 44.8 (95 % CI 37.4-53.6) for adult onset E., which is significantly higher as compared to our previous study. The overall incidence of E. in northern Italy is stable over time. We detected a significant decrease in incidence of childhood and adolescence E. and an increase in adult-onset E. The burden of epilepsy will increase as the population continues to age

Early predictors of intractability in childood epilepsy: a community-based case-control study in Copparo, italy
No full textOBJECTIVES: To identify early predictors of intractability in childhood and adolescence epilepsy. MATERIALS AND METHODS: We carried out a community-based case-control study using the incidence cohort of epileptic patients living in the district of Copparo, in the province of Ferrara, Italy. The comparative study was performed in 31 cases and 95 controls. Cases were patients who averaged at least 1 unprovoked seizure per month during an observational period of at least 2 years. Controls were subjects having achieved remission for at least 5 years regardless of current therapy. RESULTS: Onset at age <1 year, remote symptomatic etiology and high frequency of seizures before therapy were found to be independent early predictors of intractability. CONCLUSION: Our study suggested that the risk of developing intractable epilepsy may, to some extent, be predicted at the time of initial diagnosis in children with early-onset epilepsy of remote symptomatic etiology, especially if seizure propensity is initially high
Risk factors for cryptogenetic and idiopathic partial epilepsy: a community-based case-control study in Copparo, Italy
No full textOBJECTIVES: The etiology of epilepsy remains unknown in most cases. We sought to investigate the role of some pre-, peri- and postnatal factors in the etiology of idiopathic and cryptogenetic partial epilepsy. METHODS: We carried out a community-based case-control study using the incidence cohort of epileptic patients living in the district of Copparo, in the province of Ferrara, Italy. The study was performed in 55 cases and 165 controls. A standardized questionnaire was used to collect information in face-to-face interviews. RESULTS: Multivariate logistic regression analysis found that a personal history of febrile convulsions [odds ratio (OR) = 4.01, 95% confidence interval (CI) = 1.3-19.1] and a family history of seizures in first-degree relatives (OR = 4.5, 95% CI = 1.8-18.6) were independent risk factors for the condition under study. We failed to demonstrate an association between partial epilepsy and previously suggested perinatal risk factors. CONCLUSION: The findings of this study further support the hypothesis of a genetic propensity for seizures, which may be expressed early by the occurrence of febrile convulsions. Copyright 2002 S.

Phenytoin-induced gingival overgrowth: A community-based cross-sectional study in ferrara, italy
No full textA community-based cross-sectional study was carried out in Ferrara, Northern Italy, to verify the frequency of gingival overgrowth in chronic phenytoin (PHT) users and the risk factors associated with its development. All subjects taking phenytoin were identified using the computerized list of drug prescriptions available in the study area. Most of the subjects were interviewed and underwent an oral examination to evaluate their periodontal condition. The prevalence of gingival enlargement in chronic PHT users was about 40%. In our study, sex, age age at onset of therapy, treatment duration, and oral hygiene were not significantly associated with the risk of developing gingival overgrowth. A direct relationship with daily dose was found to be an independent risk factor. Younger age and poorer oral hygiene seemed to predispose to the severest level of gingival involvement. These results support data from experimental studies by suggesting that drug-induced gingival overgrowth is a dose-dependent side effect whose severity could be affected by local factors
A prospective study on the predictive value of CSF oligoclonal bands and MRI in acute isolated neurological syndromes for subsequent progression to multiple sclerosis
No full textA prospective study in patients with a clinical acute isolated brainstem or spinal cord disorder was undertaken. The aim was to evaluate the predictive value of IgG intrathecal synthesis (through the detection of oligoclonal bands in CSF) and MRI lesions at presentation, for the subsequent progression to multiple sclerosis. Forty four patients took part in this study: 22 had a brainstem disorder and 22 a spinal cord disorder. After a mean period of 26 (SD 22) months, 30 patients (68.2%) developed clinically definite multiple sclerosis. The remaining 14 patients were followed up for more than seven years. Twenty six (59.1%) patients had oligoclonal bands in CSF, with a sensitivity of 80.0%, specificity of 85.7%, and a predictive value of 92.2%. Magnetic resonance imaging showed disseminated white matter lesions in 22 patients (50.0%), with a sensitivity of 60.0%, a specificity of 71.4%, and a predictive value of 81.7%. The difference between patients with multiple sclerosis and patients without the disease was statistically significant for the findings of an IgG intrathecal synthesis (P < 0.001). It was only borderline for the MRI findings (P = 0.052). Thus the detection of an intrathecal synthesis at presentation seemed to be a better prognostic indicator of the progression to multiple sclerosis in patients affected by acute isolated brainstem or spinal cord syndromes
MULTIPLE-SCLEROSIS - DOES EPIDEMIOLOGY CONTRIBUTE TO PROVIDING ETIOLOGIC CLUES
No full textThe epidemiological approach has undoubtedly contributed to our knowledge of Multiple Sclerosis (MS) by providing some etiological hypotheses in spite of the fact that a definitive basis for the conclusive resolution of its enigma is still lacking. Epidemiological studies have indicated that MS has an uneven geographical distribution and a changing incidence over time at least in several areas of the world: this suggests an etiological role of both genetic and environmental factors. The racial difference in disease risk, the results of familial and twin studies as well as the association between MS and some HLA markers, support the great importance of genetic factors. On the other hand, the evidence of temporal trends and the data from migrant studies seem to underline the etiological contribution of environmental factors. In the light of these results much of the present views have emerged interpreting the disease as caused by multiple factors acting at a susceptible age in genetically predisposed subjects
Prognosis of childhood epilepsy: A community-based study in Copparo, Italy
No full textWe performed a community-based study among children and adolescents with idiopathic and cryptogenic epilepsy and onset of the seizures between 0 and 19 years of age on the prognosis of being seizure-free. The study population was recruited during a descriptive investigation in the Local Health Service of Copparo (USL 34), Ferrara, Northern Italy. We included 111 patients (61 males and 50 females). The average length of follow-up was 18.8 years (ranging from 7 to 24 years). The cumulative probability of being in remission was 81.2% at 15 years after onset and the estimated percentage of patients in remission without therapy was 56 % for the same time period. At 15 years after the onset of epilepsy, approximately 20% of patients continued to have seizures; nearly 25% continued to take antiepileptic drugs but had been free of seizures for at least 5 years; nearly 56% had been without seizures and free of medication for at least 5 years. Seizure type, gender, age at onset of the illness, epileptic abnormalities on EEG, family history of convulsive disorders, number and frequency of seizures prior to the start of treatment were found not to be helpful as prognostic factors. This community study, carried out on patients without the well known factors that adversely affect prognosis, confirms that the prospect of seizure control and for withdrawal of therapy is (generally) good
