Reliability of patterns of hippocampal sclerosis as predictors of postsurgical outcome

EPILEPSIA, Issue 9 2010
Maria Thom
Summary Purpose:, Around one-third of patients undergoing temporal lobe surgery for the treatment of intractable temporal lobe epilepsy with hippocampal sclerosis (HS) fail to become seizure-free. Identifying reliable predictors of poor surgical outcome would be helpful in management. Atypical patterns of HS may be associated with poorer outcomes. Our aim was to identify atypical HS cases from a large surgical series and to correlate pathology with clinical and outcome data. Methods:, Quantitative neuropathologic evaluation on 165 hippocampal surgical specimens and 21 control hippocampi was carried out on NeuN-stained sections. Neuronal densities (NDs) were measured in CA4, CA3, CA2, and CA1 subfields. The severity of granule cell dispersion (GCD) was assessed. Results:, Comparison with control ND values identified the following patterns based on the severity and distribution of neuronal loss: classical HS (CHS; n = 60) and total HS (THS; n = 39). Atypical patterns were present in 30% of cases, including end-folium sclerosis (EFS; n = 5), CA1 predominant pattern (CA1p; n = 9), and indeterminate HS (IHS, n = 35). No HS was noted in 17 cases. Poorest outcomes were noted for no-HS, and CA1p groups with 33,44% International League Against Epilepsy (ILAE) class I at up to 2 years follow-up compared to 69% for CHS (p < 0.05). GCD associated with HS type (p < 0.01), but not with outcome. Conclusions:, These findings support the identification and delineation of atypical patterns of HS using quantitative methods. Atypical patterns may represent distinct clinicopathologic subtypes and may have predictive value following epilepsy surgery. [source]


Assessment and surgical outcomes for mild type I and severe type II cortical dysplasia: A critical review and the UCLA experience

EPILEPSIA, Issue 6 2009
Jason T. Lerner
Summary Recent findings on the clinical, electroencephalography (EEG), neuroimaging, and surgical outcomes are reviewed comparing patients with Palmini type I (mild) and type II (severe) cortical dysplasia. Resources include peer-reviewed studies on surgically treated patients and a subanalysis of the 2004 International League Against Epilepsy (ILAE) Survey of Pediatric Epilepsy Surgery. These sources were supplemented with data from University of California, Los Angeles (UCLA). Cortical dysplasia is the most frequent histopathologic substrate in children, and the second most common etiology in adult epilepsy surgery patients. Cortical dysplasia patients present with seizures at an earlier age than other surgically treated etiologies, and 33,50% have nonlocalized scalp EEG and normal magnetic resonance imaging (MRI) scans. 2-(18F)Fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) is positive in 75,90% of cases. After complete resection, 80% of patients are seizure free compared with 20% with incomplete resections. Compared with type I, patients with type II cortical dysplasia present at younger ages, have higher seizure frequencies, and are extratemporal. Type I dysplasia is found more often in adult patients in the temporal lobe and is often MRI negative. These findings identify characteristics of patients with mild and severe cortical dysplasia that define surgically treated epilepsy syndromes. The authors discuss future challenges to identifying and treating medically refractory epilepsy patients with cortical dysplasia. [source]


The concept of the epilepsy syndrome: How useful is it in clinical practice?

EPILEPSIA, Issue 2009
Ettore Beghi
Summary An epilepsy syndrome is a disorder characterized by a cluster of symptoms and signs customarily occurring in combination. A syndromic approach to the epilepsies would be of practical value for diagnostic, prognostic, and therapeutic purposes. However, despite considerable efforts by leaders in the field of epileptology and the improved knowledge of the clinical, genetic, imaging, and biologic aspects of epilepsy, there are no measurable objective criteria for recognizing seizure types and epilepsy syndromes as separate diagnostic entities with well-defined prognostic and therapeutic aspects. The lack of pragmatic, evidence-based instruments to devise a syndromic classification useful for clinical practice can be explained by the evolving concept of epilepsy syndrome, its dynamic characteristics, the poor prognostic predictivity, and the extremely complex genetic and pathophysiologic mechanisms underlying the epileptic phenomena. In addition, the results of the published reports on epilepsy syndromes are mostly biased by flaws in the study population, design, and statistical analysis. The Classification Core Group of the International League Against Epilepsy (ILAE), which is working on a new classification of the epilepsies, stated that the process of syndrome identification requires that an evidence-based approach be applied to the published literature and future studies.

Notes on the origins of Epilepsia and the International League Against Epilepsy

EPILEPSIA, Issue 3 2009
Simon D. Shorvon
Summary The recent discovery of archival material has shed interesting light on the origins of Epilepsia and also the International League Against Epilepsy (ILAE). The idea of an international journal devoted to epilepsy seems first to have arisen from talks between Dr. L. J. J. Muskens and Dr. W. Aldren Turner in 1905. A protracted series of subsequent letters between Muskens and a Haarlem publisher show how the idea slowly took shape. The committee of patronage, editorial board, and editorial assistants was probably first approached at the First International Congress of Psychiatry, Neurology, Psychology, and Nursing of the Insane, held in Amsterdam in 1907. At this meeting, the concept of an international organization to fight epilepsy (to become the ILAE) was also first proposed in public, again by Muskens. The concept of the ILAE was clearly modeled on another international organization,the International Commission for the Study of the Causes of Mental Diseases and Their Prophylaxis. This Commission had been first publicly proposed in 1906 by Ludwig Frank, at the Second International Congress for the Care and Treatment of the Insane. The proposed Commission and ILAE shared many features, aims, and personnel. Despite an auspicious start, the International Commission was prevented by personal and political differences from ever actually coming into being. However, the first issue of Epilepsia appeared in March 1909 and the ILAE was inaugurated in August 1909; and both have flourished and celebrate their centenaries this year. [source]


The Early History (1909,1961) of Epilepsia, the Journal of the International League Against Epilepsy, and Its Echoes Today

EPILEPSIA, Issue 1 2007
Simon Shorvon
Summary:, This paper records the history of Epilepsia, the journal of the International League Against Epilepsy, from its inception in 1908/1909 until the beginning of its fourth series in 1961. During this time, publication was interrupted on three occasions and so the journal appeared in four series, with a complex numbering system. Over the years, the content and format of the journal has varied. Its role has changed over the years, at times primarily as a scientific organ and at other times as a source of ILAE news and reports. Concerns throughout its history have included its role as an historical record, its international representation, financial vicissitude, quality of papers, the balance between basic and clinical science, the value of clinical papers, and issues of overspecialization. Epilepsia is today the leading clinical epilepsy journal; but these are still significant concerns, and a knowledge of the history of Epilepsia is important for understanding the current position of the journal.

The Founding of the American Epilepsy Society: 1936,1971

EPILEPSIA, Issue 1 2007
Howard P. Goodkin
Summary:, In December 1946, a joint meeting devoted to epilepsy research and care was held by the Association for the Research in Nervous and Mental Disease and the American Chapter of the International League Against Epilepsy. The American Epilepsy Society (AES) has chosen this date and this meeting to mark its founding and recognizes Dr. Charles D. Aring as the organization's first president. However, the founding process of the AES actually began a decade earlier with a dinner meeting held during the American Medical Association's annual meeting. Based on this historical review, it is recommended that the AES recognize 1936 as the year of its founding and Dr. William G. Lennox as its founder and first president. [source]


Specific Epileptic Syndromes Are Rare Even in Tertiary Epilepsy Centers: A Patient-oriented Approach to Epilepsy Classification

EPILEPSIA, Issue 3 2004
Christoph Kellinghaus
Summary: Purpose: To assess the practicability and reliability of a five-dimensional patient-oriented epilepsy classification and to compare it with the International League Against Epilepsy (ILAE) classification of epilepsy and epileptic syndromes. The dimensions consist of the epileptogenic zone, semiologic seizure type(s), etiology, related medical conditions, and seizure frequency. Methods: The 185 epilepsy patients (94 adults, 91 children, aged 18 years or younger) were randomly selected from the database of a tertiary epilepsy center and the general neurological department of a metropolitan hospital (28 adults). The charts were reviewed independently by two investigators and classified according to both the ILAE and the patient-oriented classification. Interrater reliability was assessed, and a final consensus among all investigators was established. Results: Only four (4%) adults and 19 (21%) children were diagnosed with a specific epilepsy syndrome of the ILAE classification. All other patients were in unspecific categories. The patient-oriented classification revealed that 64 adults and 56 children had focal epilepsy. In an additional 34 adults and 45 children, the epileptogenic zone could be localized to a certain brain region, and in 14 adults and five children, the epileptogenic zone could be lateralized. Fourteen adults and 21 children had generalized epilepsy. In 16 adults and 14 children, it remained unclear whether the epilepsy was focal or generalized. Generalized simple motor seizures were found in 66 adults and 52 children, representing the most frequent seizure type. Etiology could be determined in 40 adults and 45 children. Hippocampal sclerosis was the most frequent etiology in adults (10%), and cortical dysplasia (9%), in children. Seven adults and 31 children had at least daily seizures. Seventeen adults and 26 children had rare or no seizures at their last documented contact. The most frequent related medical conditions were psychiatric disorders and mental retardation. Interrater agreement was high (kappa values of 0.8 to 0.9) for both the patient-oriented and the ILAE classification. Conclusions: Specific epilepsy syndromes included in the current ILAE classification are rare even in a tertiary epilepsy center. Most patients are included in unspecific categories that provide only incomplete information. In contrast, all of the patients could be classified by the five-dimensional patient-oriented classification, providing all essential information for the management of the patients with a high degree of interrater reliability.

Tonic,Absence Seizures: An Underrecognized Seizure Type

EPILEPSIA, Issue 3 2003
Tina T. Shih M.D.
Summary: ,Purpose: The individual electroclinical patterns,tonic seizures with generalized paroxysmal fast activity (GPFA, activity >13 Hz), and absence seizures with generalized slow spike-and-wave activity (GSS&W, <3 Hz),have been extensively described in the literature. However, only passing reference was made to the pattern of GPFA followed by GSS&W. In addition, these descriptions were formulated in the pre-EMU (Epilepsy Monitoring Unit) era, without benefit of video/clinical correlation. We now characterize this underrecognized seizure type. Methods: We retrospectively reviewed the data from eight patients with seizures that demonstrated this stereotyped EEG and clinical pattern. Results: We identified eight patients (six female patients; age 6,29 years; age at seizure onset, neonate to 10 years) who were evaluated at the Columbia University Epilepsy Monitoring Units between 1993 and 2002. All eight had an International League Against Epilepsy (ILAE) diagnosis of symptomatic generalized epilepsy, with six of eight manifesting multiple seizure types, six of eight with mild static encephalopathy, and two with normal cognition. A total of 29 seizures of this pattern was recorded; 26 of 29 seizures demonstrated GPFA (frequency between 14 and 30 Hz, lasting 2,8 s) followed by GSS&W (frequency range between 1 and 2 Hz, lasting 3,50 s). The predominant clinical correlate was bilateral tonic activity followed by a period of inattentiveness. In general, these seizures were differentiated from the patient's typical tonic seizures by this protracted period of impaired attentiveness. Conclusions: We describe a heretofore underrecognized and poorly characterized seizure type in patients with symptomatic generalized epilepsy, which we have termed tonic,absence seizures. Clinically and electrographically, this consists of a tonic seizure with GPFA followed by an absence seizure with GSS&W. [source]


Nonsymptomatic Generalized Epilepsy in Children Younger than Six Years: Excellent Prognosis, but Classification Should Be Reconsidered after Follow-up: The Dutch Study of Epilepsy in Childhood

EPILEPSIA, Issue 7 2002
C. M. Middeldorp
Summary: ,Purpose: To assess the prognosis and the accuracy of the epilepsy classification in young children with nonsymptomatic generalized epilepsy. Methods: Of the cohort of the Dutch Study of Epilepsy in Childhood (n = 466), all children younger than 6 years with a diagnosis of idiopathic (IGE) or cryptogenic (CGE) generalized epilepsy either at intake (n = 108) and/or after 2 years of follow-up (n = 102) were included. The number of reclassifications after 2 years was determined, and the reasons for reclassification were analyzed. All children receiving a diagnosis of IGE or CGE at 2 years were followed up for 5 years to study their outcome in terms of terminal remission (TR). Data on their level of intellectual functioning were collected at the start of this analysis. Results: The epilepsy syndrome was reclassified in 17 children. In 14 of them, the seizure type also was reclassified, and in three, the course of the epilepsy determined the new epilepsy type. Two other children had a reclassification of their seizure types without a change of the epilepsy type. Many children were categorized as having IGE not otherwise specified. In all probability, this is a heterogeneous group, containing patients with various epilepsy syndromes, with generalized tonic,clonic seizures as a common hallmark. Of the 102 children with IGE or CGE at 2 years of follow-up, 75% had a TR of >6 months after 2 years, and 85% a TR of ,1 year after 5 years. Conclusions: In a fair proportion of children with nonsymptomatic generalized epilepsy in this age group, it is not possible to classify firmly the epilepsy and/or the seizures immediately after the intake. Instead, they are reclassified during the course of the disease. This and the apparent heterogeneity of the category IGE not otherwise specified point to inherent drawbacks of the current International League Against Epilepsy (ILAE) classification of epilepsy and epileptic syndromes. The prognosis of IGE at this young age is generally excellent. [source]

The health-related quality of life of childhood epilepsy syndromes

JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 9 2003
M Sabaz
Objective: There is increasing awareness of the importance of assessing physical, psychological, social and behavioural well-being in chronic disease. The aim of this study was to examine the health-related quality of life (HRQoL) of children with common epilepsy syndromes and to explore if there are HRQoL differences between those syndromes. Methods: Each child had their epilepsy syndrome defined according to the International League Against Epilepsy classification. Epilepsy syndromes included symptomatic frontal, temporal, parietal/occipital lobe and partial unlocalized epilepsy, and two idiopathic epilepsies, childhood absence epilepsy (CAE) and benign rolandic epilepsy (BRE). Seizure semiology and ictal/interictal electroencephalogram (EEG) were determined for symptomatic partial epilepsy syndromes by video-EEG monitoring. HRQoL was evaluated with an epilepsy-specific instrument, the Quality of Life in Childhood Epilepsy Questionnaire, and two generic instruments, the Child Health Questionnaire and Child Behavior Checklist. Results: Children with symptomatic partial epilepsy syndromes were affected by epilepsy in a similar way and did not have unique HRQoL profiles. However, these children had significantly lower HRQoL scores compared to those with CAE or BRE. All children with epilepsy regardless of syndrome had a higher frequency of behavioural problems compared to normative data. Conclusion: These results indicate that children with epilepsy regardless of syndrome require evaluation of the psychosocial implications. There is a greater impact on HRQoL in symptomatic epilepsy compared to idiopathic epilepsy. Specific symptomatic partial syndromes did not differ in the degree they affect HRQoL. These findings have important implications for clinicians caring for children with epilepsy. [source]


A Merger of Movements: Peace and Civil Rights Activism in Postwar Miami

PEACE & CHANGE, Issue 2 2010
Raymond A. Mohl
This article suggests the importance of studying local peace movements in postwar America, as civil rights historians have been doing for two decades. The article also argues that peace and civil rights often reflected the same progressive impulse for social justice,thus the importance of exploring the relationships and interconnections between the two movements. This case study of peace and civil rights in postwar Miami documents the role of politically progressive Jews, especially Jewish women, in forging a social justice movement focused on peace, civil liberties, and civil rights. Mostly newcomers from northern cities, a small group of activist Jews played a major organizational role in local branches of such civil rights and peace groups as the Civil Rights Congress, the Congress of Racial Equality, the Women's International League for Peace and Freedom, the National Committee for a Sane Nuclear Policy, and Women Strike for Peace. For those who chose the activist path, peace and civil rights became inseparable components of a local social justice crusade challenging racial segregation and national Cold War policies. [source]


Juvenile idiopathic arthritis profile in Turkish children

PEDIATRICS INTERNATIONAL, Issue 2 2008
Mustafa Yilmaz
Abstract Background: Juvenile idiopathic arthritis (JIA) is a heterogeneous group of disorders. Publications from different countries point to differences in the disease manifestation of JIA among different populations. The aim of the present paper was to evaluate the clinical and laboratory features of JIA in Turkish children. Methods: A total of 196 JIA patients who fulfilled International League of Associations for Rheumatology (ILAR) diagnostic criteria were included in this retrospective study. The data collected were age, gender, age at disease onset and at diagnosis, and follow-up duration. Antinuclear antibody (ANA), rheumatoid factor (RF), and human leukocyte antigen B-27 were evaluated for each patient. Results: There were 102 boys and 94 girls with a mean duration of disease of 4.1 years. The mean age at the first visit was 8.8 years, and the mean age at onset of disease was 6.8 years (range, 8 months,15 years). Polyarticular JIA was the most frequent onset type (37.2%). Other subtypes included oligoarthritis (34.2%), systemic arthritis (15.3%), psoriatic arthritis (1%), enthesitis-related arthritis (9.7%), and other arthritis (2.2%). ANA was positive in 28 patients (14.2%). Chronic uveitis occurred in two patients with oligoarthritis; and two patients with enthesitis-related arthritis had acute uveitis. Three patients (1.4%) developed amyloidosis. Conclusion: Compared to reports from Western countries, remarkably different features of JIA were found in Turkish children, which included higher frequency of polyarticular JIA, higher prevalence among boys, lower rate of ANA positivity and uveitis. Further studies are required to understand how genetic and environmental differences affect JIA expression. [source]


Juvenile idiopathic arthritis and HLA Class I and Class II interactions and age-at-onset effects

ARTHRITIS & RHEUMATISM, Issue 6 2010
Jill A. Hollenbach
Objective The aim of this study was to quantitate risk and to examine heterogeneity for HLA at high resolution in patients with the most common subtypes of juvenile idiopathic arthritis (JIA), IgM rheumatoid factor,negative polyarticular JIA and oligoarticular JIA. Use of 4-digit comprehensive HLA typing enabled great precision, and a large cohort allowed for consideration of both age at disease onset and disease subtype. Methods Polymerase chain reaction,based high-resolution HLA typing for class I and class II loci was accomplished for 820 patients with JIA and 273 control subjects. Specific HLA epitopes, potential interactions of alleles at specific loci and between loci (accounting for linkage disequilibrium and haplotypic associations), and an assessment of the current International League of Associations for Rheumatology classification criteria were considered. Results An HLA,DRB1/DQB1 effect was shown to be exclusively attributable to DRB1 and was similar between patients with oligoarticular JIA and a younger subgroup of patients with polyarticular JIA. Furthermore, patients with polyarticular JIA showed age-specific related effects, with disease susceptibility in the group older than age 6 years limited to an effect of the HLA,DRB1*08 haplotype, which is markedly different from the additional susceptibility haplotypes, HLA,DRB1*1103/1104, found in the group with oligoarticular JIA and the group of younger patients with polyarticular JIA. Also in contrast to findings for oligoarticular JIA, patients with polyarticular arthritis had no evidence of an HLA class I effect. Markers associated with a reduced risk of disease included DRB1*1501, DRB1*0401, and DRB1*0701. DRB1*1501 was shown to reduce risk across the whole cohort, whereas DRB1*0401 and DRB1*0701 were protective for selected JIA subtypes. Surprisingly, the disease predisposition mediated by DPB1*0201 in individuals without any disease-predisposing DRB1 alleles was great enough to overcome even the very strong protective effect observed for DRB1*1501. Conclusion Inherited HLA factors in JIA show similarities overall as well as differences between JIA subtypes. [source]


Guidelines for the use of EEG methodology in the diagnosis of epilepsy

ACTA NEUROLOGICA SCANDINAVICA, Issue 1 2002
International League Against Epilepsy: Commission Report Commission on European Affairs: Subcommission on European Guidelines
The Commission of European Affairs of the International League Against Epilepsy published `Appropriate Standards for Epilepsy Care Across Europe' which contained recommendations for the use of electroencephalography (EEG) in the diagnosis of epilepsy (Brodie et al. Epilepsia 1997; 38:1245). The need for a more specific basic document of EEG methodology was recognized and the Subcommission on European Affairs was asked to produce more detailed guidelines to be used across Europe recognizing the range of practices in EEG laboratories. There are many general guidelines published on EEG methodology but this document focuses on the diagnosis of epilepsy. Details from previously published guidelines are included in references and in an appendix. These guidelines are not meant to be used as minimal standards but recommendations that can be applied to all EEG laboratories despite variations in equipment. [source]
