    Health care resource utilization in patients with active epilepsy

    EPILEPSIA, Issue 5 2010
    Tobias Kurth
    Summary Purpose:, To evaluate health care resource utilization (HRU) in active epilepsy. Methods:, Thomson-Reuters insurance databases included 14 million persons in 2005,2007. We extracted information for individuals with insurance claims suggestive of epilepsy. Using iterative expert classification, we sorted patients by type of epilepsy. For each type we calculated prevalence and HRU. A distance analysis identified closely similar types, and a principal components analysis revealed dimensions of variation in HRU. Results:, The prevalence of active epilepsy was 3.4 per 1,000. Most common diagnoses among 46,847 patients were generalized convulsive epilepsy (33.3%) and complex partial seizures (24.8%). Patients averaged 10 physician visits per year, 24 diagnostic tests/procedures per year, >30 drug dispensings per year, and <1 emergency room (ER) visit per year, the minority of each of these being related to epilepsy. Female patients generally had more HRU, and HRU increased with age. Patients were hospitalized most frequently for disorders other than epilepsy. HRU was similar for most epilepsy types, excepting grand mal status, epilepsia partialis continua, and infantile spasms. The first principal components of HRU variation was nonepilepsy HRU, followed by components of epilepsy-related medications, other epilepsy/emergency care, and epilepsy visits/diagnostic procedures. Discussion:, The prevalence of active epilepsy in the United States is substantially less than the prevalence of any history of recurrent seizure. Nonepilepsy-related HRU dominated HRU in epilepsy patients and was the principal source of variation. There is a core set of epilepsy diagnoses, the HRU patterns of which are indistinguishable, whereas patients with grand mal status, epilepsia partialis continua, and infantile spasms all have distinct patterns. To provide more specific insights into the economic impact of the condition, studies of HRU in epilepsy should make a distinction about epilepsy-related and unrelated care. [source]

    Characterization of the Tetanus Toxin Model of Refractory Focal Neocortical Epilepsy in the Rat

    EPILEPSIA, Issue 2 2005
    Karen E. Nilsen
    Summary:,Purpose: To characterize in detail a model of focal neocortical epilepsy. Methods: Chronic focal epilepsy was induced by injecting 25,50 ng of tetanus toxin or vehicle alone (controls) into the motor neocortex of rats. EEG activity was recorded from electrodes implanted at the injection site, along with facial muscle electromyographic (EMG) activity and behavioral monitoring intermittently for up to 5 months in some animals. Drug responsiveness was assessed by using the antiepileptic drugs (AEDs) diazepam (DZP) and phenytoin (PHT) delivered systemically, while 1,2,3,4-tetrahydro-6-nitro-2,3-dioxo-benzo[f]quinoxaline-7-sulfonamide (NBQX), a competitive antagonist at AMPA receptors, was administered directly to the brain to investigate the potential benefits of focal drug delivery. Results: Tetanus toxin induced mild behavioral seizures that persisted indefinitely in all animals. EEG spiking activity, occurring up to 80% of the time, correlated with clinical seizures consisting of interrupted behavioral activity, rhythmic bilateral facial twitching, and periods of abrupt motor arrest. Seizures were refractory to systemic administration of DZP and PHT. However, focal delivery of NBQX to the seizure site reversibly reduced EEG and behavioral seizure activity without detectable side effects. Conclusions: This study provides a long-term detailed characterisation of the tetanus toxin model. Spontaneous, almost continuous, well-tolerated seizures occur and persist, resembling those seen in neocortical epilepsy, including cortical myoclonus and epilepsia partialis continua. The seizures appear to be similarly resistant to conventional AEDs. The consistency, frequency, and clinical similarity of the seizures to refractory epilepsy in humans make this an ideal model for investigation of both mechanisms of seizure activity and new therapeutic approaches.

    Coexistence of movement disorders and epilepsia partialis continua as the initial signs in probable Creutzfeldt,Jakob disease

    MOVEMENT DISORDERS, Issue 9 2005
    Berril Donmez MD
    Abstract Movement disorders and epilepsy rarely occur in the early stage of Creutzfeldt,Jakob disease (CJD) but have not been reported concurrently. We report on a 47-year-old patient with probable CJD who presented with generalized chorea and focal dystonia with myoclonic jerks on the right hand. Myoclonic jerks progressed to epilepsia partialis continua within 5 days of admission to the hospital. The diagnosis of our patient was compatible with probable CJD on the basis of clinical course, electroencephalogram, and diffusion-weighted magnetic resonance imaging findings, and presence of 14-3-3 protein in cerebrospinal fluid. To our knowledge, this is the first report of a case developing both movement disorders and epilepsia partialis continua in the early stage of the disease. © 2005 Movement Disorder Society [source]

    Novel movement disorder of the lower lip: Is it epilepsia partialis continua?

    MOVEMENT DISORDERS, Issue 7 2005
    Clues from a secondary case
    Abstract A 28-year-old woman developed an acute-onset novel movement disorder of the lower lip mimicking focal dystonia. Investigations showed it to be a presentation of epilepsia partialis continua occurring in association with agenesis of the corpus callosum. It responded favorably to anti-epileptic drug therapy. Recently, Kleopa and Kyriakides1 reported on 4 patients who developed sudden-onset movement disorder characterized by a tonic sustained, lateral and outward protrusion of half of the lower lip. They failed to find any causative factors, despite extensive investigation. Treatment with anticholinergics, clonazepam, and botulinum toxin injection failed to improve the movement disorder. I present an additional case of similar focal movement disorder occurring in the presence of agenesis of the corpus callosum. A scalp electroencephalogram revealed focal epileptic activity, and the movement disorder responded favorably to treatment with antiepileptic drugs. © 2005 Movement Disorder Society [source]

    Dystonia, athetosis, and epilepsia partialis continua in a patient with late-onset Rasmussen's encephalitis,

    MOVEMENT DISORDERS, Issue 3 2002
    Steven Frucht MD
    Rasmussen's encephalitis is a rare autoimmune disorder characterized by intractable epilepsy and progressive hemispheric dysfunction. The disorder usually affects children, although cases have been reported with symptom onset in late adolescence or adulthood. Myoclonus is common in Rasmussen patients, usually occurring as part of epilepsia partialis continua (EPC); however, other hyperkinetic movements are rare. This report documents a 19-year-old woman with Rasmussen's encephalitis whose clinical presentation was dominated by foot dystonia, arm athetosis, and EPC. Intravenous immunoglobulin improved both hyperkinetic movements and EPC, but benefit was transient. The clinical significance and implications of these findings are discussed. © 2002 Movement Disorder Society [source]
