    To investigate the current status of epilepsy treatment and the efficacy and adverse effects of phenobarbital therapy in rural areas of Northern China. A total of 2192 patients diagnosed with convulsive epilepsy were recruited from seven different rural regions in Jilin Province, China to investigate the current status of epilepsy treatment, and 1379 of them were enrolled in a standard phenobarbital therapy trial. Patients were selected according to strict inclusion and exclusion criteria, and medical records for all patients were collected and analyzed before the standard treatment was started. Patients were followed up monthly, and efficacy in 1218 patients was analyzed at 1, 3, 6 and 12 months of treatment. More patients had the initial seizure in juveniles than in adults, and 40.72% of the 2192 patients were not receiving any treatment before the treatment trial. The efficacy of phenobarbital increased and adverse effects decreased within the treatment period. Among the 349 patients who were followed up for 12 months from the beginning of the phenobarbital treatment, seizures were decreased by more than 75% in 71.3% of patients using a low-to-medium dose of phenobarbital. Major adverse effects of phenobarbital included mild exhaustion, drowsiness, dizziness and headache. Standardized long-term and regular administration of phenobarbital at a low-to-medium dose can be used as an effective, economic and safe treatment against epilepsy in rural areas.

    This article reviews the current position of phenobarbital using articles published since 2000 and speculates on its likely future contribution to epilepsy care. Over the last decade there have been no major double-blind randomized placebo-controlled or comparative trials with phenobarbital. Previous studies have suggested that phenobarbital is as effective in monotherapy as phenytoin and carbamazepine. Several observational studies undertaken in developing countries over the last decade have confirmed its efficacy and safety for the common epilepsies. This was particularly so in the substantial demonstration project undertaken in rural China under the auspices of the World Health Organization in partnership with the International League Against Epilepsy and International Bureau for Epilepsy. Phenobarbital is still widely used for neonatal and childhood seizures and for drug-resistant convulsive and nonconvulsive status epilepticus. Recent data have confirmed in a prospective cohort of women taking phenobarbital as monotherapy that the drug can be associated with a range of congenital defects in exposed infants. Much effort has gone into exploring the apparent contradiction of higher withdrawal rates due to cognitive and behavioral side effects in studies undertaken in developed countries but not in those sited in the developing world. A raft of data over the last 10 years, including a systematic review, showed no important differences between the tolerability of phenobarbital compared to that with other antiepileptic drugs. Finally, cognitive test scores and mood ratings in 136 people with epilepsy receiving phenobarbital for a year were similar to those in 137 age-, sex-, and education-matched controls in a number of Chinese villages. Indeed, there were some cognitive gains in the patients possibly due to improved seizure control. Phenobarbital is still the most cost-effective pharmacologic treatment for epilepsy. All these data predict a healthy future for

    Full Text Available Objective: To optimize the use of phenobarbital and/or phenytoin as frontline drugs for treatment of childhood epilepsy. Design: Before-and -after study. Setting: Epilepsy clinic at paediatric OPD, Sassoon General Hospital, Pune. Materials and Methods: Epilepsy is a condition in which seizures are triggered recurrently from within the brain. For epidemiological classification purpose epilepsy is considered to be present when two or more unprovoked seizures occur at an interval greater than twenty four hours apart. Seizures were classified as generalized and partial seizures, with underlying etiology investigated with EEG, CT scan in majority of the patients. Follow - up rate, seizure - control and antiepileptic drugs used among 151 children enrolled as on 31 March 2005 were compared with 106 children with new onset epilepsy enrolled as on February 2006. Eight children with breakthrough convulsion after a seizure free period of five to eighteen months were followed up after injection vitamin D. Nineteen children with poor control of seizures receiving polytherapy with newer antiepileptic drugs were assessed with frontline antiepileptic medication of phenobarbital and/or phenytoin. Serum calcium, phosphorus, alkaline phosphatase were done in seventy two consecutive children with seizure disorder. Results: During post protocol period good seizure control was achieved in 84.8% as against 80.7% and use of phenobarbital and/or phenytoin increased to 65.11% from 22.87%. Of the 8 cases with breakthrough seizures seven remained seizure free after vitamin D administration and with no dose enhancement of AED medications of the nineteen. Children receiving polytherapy thirteen children could be successfully switched to phenobarbital and/or phenytoin. Forty four (61% children had hypocalcemia (less than 9 mg%, fifty seven (79% children had raised alkaline phosphatase levels (more than 270 IU. Comments: Phenobarbital and/or phenytoin have been found to be

    To evaluate the long-term outcome of phenobarbital treatment for convulsive epilepsy in rural China, and to explore factors associated with overall seizure outcomes. We carried out follow-up assessments of people who took part in an epilepsy community management program conducted in rural counties of six provinces in China. People with convulsive epilepsy who were previously untreated (or on irregular treatment) were commenced on regular treatment with phenobarbital. Information was collected using a standardized questionnaire by face-to-face interviews of the individuals (and their families where necessary). Information collected included treatment status, medication change, seizure frequency, and mortality. Among the 2,455 people who participated in the original program, outcomes were successfully ascertained during the follow-up assessment in 1986. Among them, 206 had died. Information on treatment response was obtained in 1,780 (56% male; mean age 33.9 years, range 3-84; mean duration of follow-up 6.4 years). Among them, 939 (53%) were still taking phenobarbital. The most common reasons for stopping phenobarbital were seizure freedom or substantial seizure reduction, socioeconomic reasons, and personal preference. Four hundred fifty-three individuals (25%) became seizure-free for at least 1 year while taking phenobarbital, 88% of whom did so at daily doses of 120 mg or below. Four hundred six (23%) reported adverse events, which led to withdrawal of phenobarbital in phenobarbital for convulsive epilepsy in rural China. One hundred years after the discovery of its antiepileptic effect, phenobarbital is still playing an important role in the management of epilepsy.

    To study the impact on seizure frequency and epileptiform discharges of children with epilepsy from topiramate (TPM) and phenobarbital (PB). Two hundred cases children with epilepsy from August 2010 to August 2013 in our hospital were sampled and randomly divided into two groups. The observation group was treated with TPM while the control group with PB, and then comparing seizure frequency, efficiency, and adverse reactions of two groups. The reduced number of partial seizures, generalized seizures, and total seizures in the observation group were significantly higher than those in the control group, and the rate of cure, markedly effective and total efficiency in observation group were significantly higher than those in the control group. However, the adverse reactions in observation group were significantly lower than those in the control group. Thus, differences were statistically significant (p<0.05). Compared with PB, TPM showed a better effect on epilepsy treatment with less adverse reactions which were worthy of clinical recommendation.

    A probable case of drug reaction with eosinophilia and systemic symptoms (DRESS) associated with consecutive use of three medications for seizure control is reported. A 36-year-old woman was treated at a community hospital for a mild fever (37.9°C) and diffuse raised maculopapular rash with erythema. Three weeks previously, she had been diagnosed with a seizure disorder and initiated on phenytoin (dose unknown) at that time; about two weeks later, she developed a rash, prompting a switch from phenytoin to extended-release divalproex sodium 250 mg orally twice daily. During the week after discontinuation of phenytoin, the rash was improving, but about five days after the initiation of divalproex therapy, she had worsening rash and pruritus requiring urgent treatment; the divalproex was discontinued, and phenobarbital 30 mg three times daily was initiated for continued seizure control. Despite the discontinuation of phenytoin and divalproex, the patient's hepatic function worsened over five days, and phenobarbital therapy was discontinued. With continued deterioration of the patient's condition to fulminant hepatic failure, a transfer to a liver transplant facility was arranged. The use of the adverse reaction probability scale of Naranjo et al. in this case yielded a score of 8, indicating a probable relationship between DRESS and the serial use of phenytoin, divalproex, and phenobarbital. After receiving phenytoin for treatment of seizure disorder, a 36-year-old woman developed a fever and maculopapular rash with erythema. This reaction continued even after drug therapy was switched to extended-release divalproex and then phenobarbital. The patient's liver function deteriorated despite discontinuation of all seizure medications.

    Phenobarbital is an effective treatment for epilepsy but concerns remain over its potential neurocognitive toxicity. This prospective study evaluated the effects of phenobarbital treatment on cognition and mood in people with epilepsy in rural China. We recruited 144 adults with convulsive seizures and 144 healthy controls from six sites in rural China. People with epilepsy were treated with phenobarbital monotherapy for 12 months. At baseline, and at 3, 6 and 12 months, cases and controls were evaluated with a battery of neuropsychological tests: the Mini-Mental State Examination, the Hamilton Depression Rating Scale, a digit span test, a verbal fluency test, an auditory verbal learning test and a digit cancellation test. Efficacy of phenobarbital treatment was evaluated at the end of follow-up for those with epilepsy. Cognitive test scores and mood ratings were available for 136 (94%) people with epilepsy and 137 (95%) controls at the 12 month follow-up. Both groups showed slightly improved performance on a number of neuropsychological measures. The people with epilepsy showed greater performance gains (p=0.012) in verbal fluency. Nine people with epilepsy complained of memory problems during the treatment period. In this study, phenobarbital was not found to have a major negative impact on cognitive function of people with convulsive seizures and some cognitive gains were observed, possibly due to improved seizure control.

    Therapeutic drug monitoring is essential for both phenytoin and phenobarbital therapy given their narrow therapeutic indexes. Nevertheless, the measurement of either phenytoin or phenobarbital concentrations might not be available in some rural hospitals. Information assisting individualized phenytoin and phenobarbital combination therapy is important. This study's objective was to determine the relationship between the maximum rate of metabolism of phenytoin (Vmax) and phenobarbital clearance (CLPB), which can serve as a guide to individualized drug therapy. Data on phenytoin and phenobarbital concentrations of 19 epileptic patients concurrently receiving both drugs were obtained from medical records. Phenytoin and phenobarbital pharmacokinetic parameters were studied at steady-state conditions. The relationship between the elimination parameters of both drugs was determined using simple linear regression. A high correlation coefficient between Vmax and CLPB was found [r=0.744; pphenobarbital. These proposed equations can be of use in aiding individualized drug therapy.

    Phenobarbital remains one of the most widely used antiepileptic drugs worldwide, yet there are limited data regarding side effects associated with its use in routine clinical care settings in low-income countries. Available data suggests that phenobarbital is as effective as other first-line drugs for treating tonic-clonic seizures, but side effect reports differ widely between high and low-income settings. A better understanding of phenobarbital side effect profile and severity in low-income settings is warranted given its role in efforts to decrease the epilepsy treatment gap. We used the Liverpool adverse events profile (LEAP) to assess side effects in consecutive patients with epilepsy on phenobarbital seeking care in rural Zambia. Data regarding age, gender, medication dose, and medication adherence were also collected. T-tests and Spearman's correlation coefficient were used to assess predictors of LEAP score and medication adherence. Thirty-five patients receiving a mean dose of 2.1mg/kg/day (SD: 2.78 mg/kg/day) of phenobarbital were assessed. All participants reported at least one side effect in the previous four weeks with a median of 6 symptoms (IQR: 4-8) and a mean side effects score of 28/76 (SD: 5.38). Over half reported sleepiness and dizziness. Memory problems and depression were also common (both 46%). Total LAEP score was not associated with age (p=0.88), gender (p=0.17), or phenobarbital dose (p=0.13). Medication adherence was not associated with side effects total score (p=0.56). Rural Zambian adults taking phenobarbital at doses recommended by the World Health Organization report a significant number of side effects. The most common side effects reported were similar to those reported in high-income countries. The significant burden of phenobarbital-associated side effects in this African cohort is in contrast to data from non-randomized clinical trials in China that reported phenobarbital to be well-tolerated with few side effects.

    Phenobarbital (phenobarbitone) was first used as an antiepileptic drug 100 years ago, in 1912. This article tells the story of the discovery of its antiepileptic action, its early development, and the subsequent course of its clinical use over the 100-year period. The side effects, pharmacokinetics, and misuse of barbiturates are considered, along with the more recent clinical trials and the drug's current clinical utilization. The introduction of controlled drug regulations, the comparative cost of phenobarbital, and its inclusion on the World Health Organization (WHO) essential drug list are discussed. It is one of the few drugs on the formulary in 1912 that is still listed today, and remarkably its efficacy in epilepsy has not been significantly bettered. The current recommendation by the WHO is that phenobarbital should be offered as the first option for therapy for convulsive epilepsy in adults and children if availability can be ensured. This is rated as a strong recommendation because of the proven efficacy and low cost of phenobarbital, and despite its perceived side-effect profile and the practical problems of access. Whether this recommendation puts "a hierarchy on the brain," as has been suggested, is arguable. Much still needs to be learned about the drug's effects, and the issues raised by phenobarbital have lessons for all antiepileptic drug therapy.

    Treatment of canine epilepsy is problematic. Few antiepileptic drugs have proven efficacy in dogs and undesirable adverse effects and pharmacoresistance are not uncommon. Consequently, the need for investigation of alternative treatment options is ongoing. The objective of this study was to investigate the efficacy and tolerability of levetiracetam as mono-therapy in dogs with idiopathic epilepsy. The study used a prospective single-blinded parallel group design. Twelve client-owned dogs were included and were randomised to treatment with levetiracetam (30 mg/kg/day or 60 mg/kg/day divided into three daily dosages) or phenobarbital (4 mg/kg/day divided twice daily). Control visits were at days 30, 60 and then every 3 months for up to 1 year. Two or more seizures within 3 months led to an increase in drug dosage (levetiracetam: 10 mg/kg/day, phenobarbital: 1 mg/kg/day). Five of six levetiracetam treated dogs and one of six phenobarbital treated dogs withdrew from the study within 2-5 months due to insufficient seizure control. In the levetiracetam treated dogs there was no significant difference in the monthly number of seizures before and after treatment, whereas in the phenobarbital treated dogs there were significantly (P = 0.013) fewer seizures after treatment. Five phenobarbital treated dogs were classified as true responders (≥50% reduction in seizures/month) whereas none of the levetiracetam treated dogs fulfilled this criterion. Adverse effects were reported in both groups but were more frequent in the phenobarbital group. In this study levetiracetam was well tolerated but was not effective at the given doses as mono-therapy in dogs with idiopathic epilepsy. Copyright © 2015 Elsevier Ltd. All rights reserved.

    We retrospectively reviewed the outcomes of children with focal epilepsy treated with oral high-dose phenobarbital. We reviewed data on children (agedphenobarbital (>5 mg/kg/day to maintain a target serum level >40 μg/mL) for at least 6 months. Seizure frequency was evaluated after phenobarbital titration, and 1 and 2 years after high-dose phenobarbital treatment commenced. Treatment was judged effective when seizure frequencies fell by ⩾75%. Seven boys and eight girls were treated. The median age at commencement of high-dose phenobarbital therapy was 30 months. The maximal serum phenobarbital level ranged from 36.5 to 62.9 μg/mL. High-dose PB was effective in seven. In two patients, treatment was transiently effective, but seizure frequency later returned to the baseline. High-dose PB was ineffective in six. No significant association between effectiveness and any clinical variable was evident. Drowsiness was recorded in nine patients, but no patient developed a behavioral problem or hypersensitivity. Oral high-dose phenobarbital was effective in 7 of 15 patients with focal epilepsy and well tolerated. High-dose PB may be useful when surgical treatment is difficult.

    Full Text Available Encephalitis presents with seizures in the acute phase and increases the risk of late unprovoked seizures and epilepsy. This study aimed to evaluate the effect of antiepileptic drugs in pediatric patients with acute seizures due to encephalitis and epilepsy.Cases of acute pediatric encephalitis between January 2000 and December 2010 were reviewed. Clinical data, including onset at age, seizure type, seizure frequency, effects of antiepileptic drugs, and prognosis were analyzed.During the study period, 1038 patients (450 girls, 588 boys were enrolled. Among them, 44.6% (463 had seizures in the acute phase, 33% had status epilepticus, and 26% (251 developed postencephalitic epilepsy. At one year of follow-up, 205 of the 251 patients with postencephalitic epilepsy were receiving antiepileptic drugs while 18% were seizure free even after discontinuing the antiepileptic drugs. Among those with postencephalitic epilepsy, 67% had favorable outcomes and were using <2 anti-epileptic drugs while 15% had intractable seizures and were using ≥ 2 antiepileptic drugs. After benzodiazepines, intravenous phenobarbital was preferred over phenytoin as treatment of postencephalitic seizures in the acute phase. For refractory status epilepticus, high-dose topiramate combined with intravenous high-dose phenobarbital or high-dose lidocaine had less side effects.Children with encephalitis have a high rate of postencephalitic epilepsy. Phenobarbital and clonazepam are the most common drugs used, alone or in combination, for postencephalitic epilepsy.

    Status epilepticus and acute prolonged seizures are the most commonly occurring neurological emergencies in children. Such events have high morbidity and mortality rates along with poor long-term outcomes, depending on their duration and causes. Therefore, such seizures warrant urgent treatment using appropriate doses of anticonvulsants. Benzodiazepines, phenobarbital, and phenytoin are the most commonly used anticonvulsants for controlling status epilepticus and acute prolonged seizures. However, these medications have several well-known adverse effects. Previous studies on both adults and children have shown the efficacy and safety of rapid infusion of valproate in controlling status epilepticus. However, few well-designed randomised trials have been carried out in children, and there remains a paucity of data regarding intravenous sodium valproate use in children. Therefore, our aim was to compare the efficacy and safety of rapid loading of valproate with those of intravenous phenobarbital in children with status epilepticus and acute prolonged seizures. Sixty children (30 in each group) with convulsive status epilepticus and acute prolonged seizures were enrolled and randomly assigned to receive either valproate or phenobarbital. The main outcome variable was termination of all convulsive activity within 20 min of starting anticonvulsant infusion. Intravenous rapid loading of valproate was successful in seizure termination in (27/30, 90%) of patients compared to phenobarbital (23/30, 77%) (p = 0.189). Clinically significant adverse effects occurred in 74% patients of the phenobarbital group and 24% patients of the valproate group (p < 0.001). In conclusion, rapid loading of valproate is effective and safe in controlling convulsive status epilepticus and acute prolonged convulsive seizures in children. Intravenous valproate should be considered as a suitable choice for terminating status epilepticus and acute prolonged seizures in children. Copyright

    This study explored the adverse effect (AE) profile of phenobarbital (PB) among patients with active convulsive epilepsy (ACE) from resource-poor areas. Patients with ACE were enrolled into an epilepsy management project in rural West China. Information was obtained from monthly follow-up questionnaires. The demographic and clinical features of the patients with AE were firstly described. After that, the occurrence rate was estimated for each subtype of AE at three different severity levels (mild, moderate, and serious). Survival analysis was used to determine the potential risk factors of AEs. A total of 7231 patients (3780 men) were included in the present cohort. During the follow-up time period (average 33.4months), the most common AEs were drowsiness (moderate: 4.4%, serious: 0.68%), dizziness (moderate: 3.7%, serious: 0.5%), and headache (moderate: 2.9%, serious: 0.41%). In the confirmed AE groups (moderate and serious severity levels), the symptoms tended to be transient, with durations of less than 3months. Polytherapy was an independent risk factor for AEs and had an increasing risk when the severity of the AE increased (Hazard Ratio 1.12, 1.55, and 2.52 for mild AE, moderate AE, and serious AE, respectively). Receiving a high dosage of PB (>180mg/day) indicated a slightly elevated risk (Hazard Ratio 1.22 and 1.27 for mild AE and moderate AE, respectively). Phenobarbital demonstrates overall tolerability, and serious AEs were not common. Patients receiving a high dose of PB or polytherapy are at increased risk of developing AEs.

    Phenobarbital or potassium bromide (KBr) add-on treatment decreases the average monthly seizure frequency in dogs with idiopathic epilepsy resistant to a maximum dose of imepitoin. The importance of continued administration of imepitoin in these dogs is currently unknown. The goal of this study was to assess whether imepitoin withdrawal would destabilize epileptic seizure control. In this prospective clinical trial epileptic seizure control was evaluated by comparing the monthly seizure frequency of 13 dogs with well-controlled idiopathic epilepsy receiving a combination of imepitoin and phenobarbital (n=4), imepitoin and KBr (n=7), and imepitoin, phenobarbital and KBr (n=2) during a period of 3-6 months (pre-withdrawal period), with a follow-up period of 9-12 months after withdrawal of imepitoin (post-withdrawal period). Adverse effects were also recorded before and after withdrawal of imepitoin. Imepitoin was tapered off over 3 months as follows: 20mg/kg twice daily for 1 month, then 10mg/kg twice daily for 1 month, then once daily for 1 month. Withdrawal of imepitoin did not increase monthly seizure frequency (P=0.9). Moreover, all owners reported improvement in the adverse effects experienced by their dog after withdrawal of imepitoin. Imepitoin withdrawal in epileptic dogs that were well-controlled with imepitoin and phenobarbital and/or KBr did not worsen epileptic seizure control, and possibly decreased antiepileptic treatment-related adverse effects. However, a worsening of seizure frequency could occur in individual cases. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Introduction: Phenytoin is one of anticonvulsant drugs (AC) which together with the Corticosteroids are used frequently in patients with intracranial tumors either early or metastatic; the association of treatments can cause adverse effects within which are skin reactions called erythema multiforme (EM) syndrome Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) whose incidence is 5 to 10%, with an increased risk are used when the AC associated with treatment with radiotherapy (RT).Case report: A 48 year old woman in whom primitive brain metastases were diagnosed breast cancer, so phenytoin, corticosteroids and performed RT presenting holoencefálica for such treatment maculo-papular skin reaction symmetrical onset zone Radiant treatment extension neck, thorax, abdomen and pelvis, oral mucositis, conjunctivitis and fever, which improved after stopping treatment altogether. Discussion: The clinical picture presented matches the description of the 30 Reported SJS / TEN in the literature with the use of AC and RT cases. The clinical course of the skin reactions in our patient represents the possible combined effect of phenytoin and RT as causative agents and analyzed the occurrence of side effects occurred in the third week of starting treatment with both therapeutic modalities such as what described in these reactions and improved frankly to stop treatment until disappear entirely. Cutaneous adverse reactions may occur as a complication severe in patients treated with RT and phenytoin and both treatments should suspend the first sign of side effects must continue once the patient recovered with AC radiant modifying drug treatment if necessary. There are differences of opinion regarding the prophylactic use of drug therapy in patients with AC intracranial tumors both early and metastatic. The American Academy of Neurology held a consensus in 2000 whose recommendations are non-routine use of AC in patients diagnosed intracerebral tumor that has not

    To compare efficacy and safety of treatment with phenobarbital or bromide as the first-choice antiepileptic drug (AED) in dogs. Double-blinded, randomized, parallel, clinical trial. 46 AED-naïve dogs with naturally occurring epilepsy. Study inclusion was based on age, history, findings on physical and neurologic examinations, and clinicopathologic test results. For either phenobarbital treatment (21 dogs) or bromide treatment (25), a 7-day loading dose period was initiated along with a maintenance dose, which was adjusted on the basis of monthly monitoring. Efficacy and safety outcomes were compared between times (baseline and study end [generally 6 months]) and between drugs. Phenobarbital treatment resulted in eradication of seizures (17/20 [85%]) significantly more often than did bromide (12/23 [52%]); phenobarbital treatment also resulted in a greater percentage decrease in seizure duration (88 ± 34%), compared with bromide (49 ± 75%). Seizure activity worsened in 3 bromide-treated dogs only. In dogs with seizure eradication, mean ± SD serum phenobarbital concentration was 25 ± 6 μg/mL (phenobarbital dosage, 4.1 ± 1.1 mg/kg [1.9 ± 0.5 mg/lb], p.o., q 12 h) and mean serum bromide concentration was 1.8 ± 0.6 mg/mL (bromide dosage, 31 ± 11 mg/kg [14 ± 5 mg/lb], p.o., q 12 h). Ataxia, lethargy, and polydipsia were greater at 1 month for phenobarbital-treated dogs; vomiting was greater for bromide-treated dogs at 1 month and study end. Both phenobarbital and bromide were reasonable first-choice AEDs for dogs, but phenobarbital was more effective and better tolerated during the first 6 months of treatment.

    Full Text Available OBJECTIVE: CYP2C9 is a major enzyme in human drug metabolism and the polymorphism observed in the corresponding gene may affect therapeutic outcome during treatment. The distribution of variant CYP2C9 alleles and prevalence of phenytoin adverse reactions were hereby investigated in a population of patients diagnosed with epilepsy. METHOD: Allele-specific PCR analysis was carried out in order to determine frequencies of the two most common variant alleles, CYP2C9*2 and CYP2C9*3 in genomic DNA isolated from 100 epileptic patients. We also analyzed the frequency of phenytoin adverse reactions among those different genotypes groups. The data was presented as mean±standard deviation. RESULTS: The mean age at enrollment was 39.6±10.3 years (range, 17-72 years and duration of epilepsy was 26.5±11.9 years (range 3-48 years. The mean age at epilepsy onset was 13.1±12.4 years (range, 1 month-62 years. Frequencies of CYP2C9*1 (84%, CYP2C9*2 (9% and CYP2C9*3 (7% were similar to other published reports. Phenytoin adverse reactions were usually mild and occurred in 15% patients, without correlation with the CYP2C9 polymorphism (p=0.34. CONCLUSION: Our findings indicate an overall similar distribution of the CYP2C9 alleles in a population of patients diagnosed with epilepsy in the South of Brazil, compared to other samples. This sample of phenytoin users showed no drug related adverse reactions and CYP2C9 allele type correlation. The role of CYP2C9 polymorphism influence on phenytoin adverse reaction remains to be determined since some literature evidence and our data found negative results.

    Phenobarbital is an anticonvulsive drug widely used in newborns with hypoxic-ischemic encephalopathy. The objective of our study was to describe possible effect of frequently co-administered medications (dopamine, dobutamine, norepinephrine, furosemide, phenytoin, and analgesics) on the phenobarbital pharmacokinetics in full term newborns with hypoxic-ischemic encephalopathy. Phenobarbital pharmacokinetic parameters (standardized intravenous loading dose was 10-20 mg/kg, maintenance dose 2-6 mg/kg/day) were computed using non-compartmental analysis. Co-medication was evaluated throughout the whole treatment period up to 5 days. Volume of distribution, clearance, and half-life median values (95 % CI) for phenobarbital in the whole study population (n=37) were 0.48 (0.41-0.56) l/kg, 0.0034 (0.0028-0.0040) l/h/kg, and 93.7 (88.1-99.2) h, respectively. Phenobarbital pharmacokinetic parameters were not significantly affected by vasoactive drugs (dopamine, dobutamine, and norepinephrine), furosemide, phenytoin, or analgesics. Furthermore, no dose-dependent alteration of phenobarbital pharmacokinetic parameters was noted for vasoactive medication at doses equivalent to cumulative vasoactive-inotropic score (area under the curve in a plot of vasoactive-inotropic score against time) 143.2-8473.6, furosemide at cumulative doses of 0.2-42.9 mg/kg, or phenytoin at cumulative doses of 10.3-46.2 mg/kg. Phenobarbital pharmacokinetics was not affected by investigated co-administered drugs used in newborns with hypoxic-ischemic encephalopathy in real clinical settings.

    A novel and simple method based on solidified floating organic drop microextraction followed by high-performance liquid chromatography with ultraviolet detection has been developed for simultaneous preconcentration and determination of phenobarbital, lamotrigine, and phenytoin in human plasma and urine samples. Factors affecting microextraction efficiency such as the type and volume of the extraction solvent, sample pH, extraction time, stirring rate, extraction temperature, ionic strength, and sample volume were optimized. Under the optimum conditions (i.e. extraction solvent, 1-undecanol (40 μL); sample pH, 8.0; temperature, 25°C; stirring rate, 500 rpm; sample volume, 7 mL; potassium chloride concentration, 5% and extraction time, 50 min), the limits of detection for phenobarbital, lamotrigine, and phenytoin were 1.0, 0.1, and 0.3 μg/L, respectively. Also, the calibration curves for phenobarbital, lamotrigine, and phenytoin were linear in the concentration range of 2.0-300.0, 0.3-200.0, and 1.0-200.0 μg/L, respectively. The relative standard deviations for six replicate extractions and determinations of phenobarbital, lamotrigine, and phenytoin at 50 μg/L level were less than 4.6%. The method was successfully applied to determine phenobarbital, lamotrigine, and phenytoin in plasma and urine samples. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Phenobarbital hypersensitivity is one of the common drug hypersensitivity syndromes in children. Clinical symptoms of phenobarbital hypersensitivity vary from maculopapular rashes (MPs) to severe cutaneous adverse drug reactions (SCARs) including drug reactions with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). Drug hypersensitivity has been demonstrated to be associated with variations in the HLA genotypes. This study was to investigate the association between the variations of HLA genotypes and phenobarbital hypersensitivity in Thai children. The cases were Thai children, between 0 and 18 years of age, who were diagnosed with phenobarbital hypersensitivity, which included SCARs and MPs. The control patients were Thai children of a corresponding age who had taken phenobarbital for at least 12 weeks without any hypersensitivity reaction. Blood samples were collected for HLA genotyping by using a reverse-sequence-specific oligonucleotide (SSO) probes method. The carrier rates of HLA alleles were compared between 47 cases (27 SCARs and 20 MPs) and 54 controls. The carrier rates of HLA-A*01:01 and HLA-B*13:01 were significantly higher in the phenobarbital-induced SCARs than in the tolerant controls (18.5% vs. 1.85%, p = 0.01, odds ratio [OR] 11.66, 95% confidence interval [CI] 1.21-578.19; 37.04% vs. 11.11%, p = 0.009, OR 4.60, 95%CI 1.29-17.98). There was a trend of a higher carrier rate of HLA-C*06:02 in the phenobarbital-induced SCARs when compared with those in the tolerant controls (29.63% vs. 11.11%, p = 0.059, OR 3.31, 95% CI 0.88-13.31). In contrast to the phenobarbital-induced SCARs, only the HLA-A*01:01 carrier rate in the phenobarbital-induced MPs was significantly higher than those in the tolerant controls (20% vs. 1.85%, p = 0.017, OR 12.69, 95% CI 1.15-661.62). An association between phenobarbital hypersensitivity and HLA-A*01:01 and HLA-B*13:01 has been demonstrated in Thai children

    Imepitoin was tested as a combination treatment with phenobarbital in an open-label mono-centre cohort study in dogs with drug-resistant epilepsy. Diagnosis of idiopathic epilepsy was based on clinical findings, magnetic resonance imaging and cerebrospinal fluid analysis. Three cohorts were treated. In cohort A, dogs not responding to phenobarbital with or without established add-on treatment of potassium bromide or levetiracetam were treated add-on with imepitoin, starting at 10 mg/kg BID, with titration allowed to 30 mg/kg BID. In cohort B, the only difference to cohort A was that the starting dose of imepitoin was reduced to 5 mg/kg BID. In cohort C, animals not responding to imepitoin at >20 mg/kg BID were treated with phenobarbital add-on starting at 0.5 mg/kg BID. The add-on treatment resulted in a reduction in monthly seizure frequency (MSF) in all three cohorts. A reduction of ≥50% was obtained in 36-42% of all animals, without significant difference between cohorts. The lower starting dose of 5 mg/kg BID imepitoin was better tolerated, and an up-titration to on average of 15 mg/kg BID was sufficient in cohort A and B. In cohort C, a mean add-on dose of 1.5 mg/kg BID phenobarbital was sufficient to achieve a clinically meaningful effect. Six dogs developed a clinically meaningful increase in MSF of ≥ 50%, mostly in cohort A. Neither imepitoin nor phenobarbital add-on treatment was capable of suppressing cluster seizure activity, making cluster seizure activity an important predictor for drug-resistance. A combination treatment of imepitoin and phenobarbital is a useful treatment option for a subpopulation of dogs with drug-resistant epilepsy, a low starting dose with 5 mg/kg BID is recommended.

    Full Text Available Background: Several »newer« antiepileptic drugs (AEDs, i.e. vigabatrin, lamotrigine, gabapentin, topiramate, tiagabine, oxcarbazepine, levetiracetam, pregabalin and zonisamide have been introduced into clinical practice within the last decade. Most of these new drugs are at least as effective as the »older« AEDs (phenobarbital, phenytoin, valproic acid, carbamazepine and in general, they seem to be better tolerated then the older drugs and have less side effects. The development of pharmaceutical industry has brought several new AEDs to clinical practice which increased a probability of therapeutic success, but also made treatment more complex. It is expected from the physician that she will know indications and contraindications for at least 15 AEDs, their optimal titration, dosage, possible side effects and wide spectrum of interactions with other drugs. At this point advertisements of drug companies try to convince us aggressively about success of their own products.Conclusions: This review article focuses on modern medicamentous treatment of adults with epilepsy, main characteristics of newer AEDs, conditions, availability and statistics of their usage in Slovenia.

This technique permits the synthesis of solids with controlled mesoporosity, where a large variety of molecules that have therapeutic activity can be hosted and further released to specific sites. In this work phenytoin (PH), a drug used in epilepsy treatment, was loaded in ordered mesoporous silica (SBA 15) and nanostructured titania tubes (TiO 2 ). The pure materials and those containing PH were characterized by X-ray diffraction, FTIR spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and N 2 adsorption-desorption at 77 K. In order to determine the loading capacity of the antiepileptic drug on these silica- and titania-based materials, the loading and release of PH was investigated using UV-vis spectroscopy. Tubular structures were found for the titania samples, for which the X-ray diffractograms showed to be formed by anatase and rutile phases. On the other hand, an amorphous phase was found in the silica sample. A highly ordered hexagonal structure of 1D cylindrical channels was also observed for this material. Loaded PH showed a good stability inside the used materials as observed by spectroscopy analysis. The adsorption and desorption of PH are faster in nanostructured TiO 2 tubes than in mesoporous silica matrix.

    There are no evidence-based guidelines on the preferred approach to treating early-life epilepsy. We examined initial therapy selection in a contemporary US cohort of children with newly diagnosed, nonsyndromic, early-life epilepsy (onset before age three years). Seventeen pediatric epilepsy centers participated in a prospective cohort study of children with newly diagnosed epilepsy with onset under 36 months of age. Details regarding demographics, seizure types, and initial medication selections were obtained from medical records. About half of the 495 enrolled children with new-onset, nonsyndromic epilepsy were less than 12 months old at the time of diagnosis (n = 263, 53%) and about half (n = 260, 52%) had epilepsy with focal features. Of 464 who were treated with monotherapy, 95% received one of five drugs: levetiracetam (n = 291, 63%), oxcarbazepine (n = 67, 14%), phenobarbital (n = 57, 12%), topiramate (n = 16, 3.4%), and zonisamide (n = 13, 2.8%). Phenobarbital was prescribed first for 50 of 163 (31%) infants less than six months old versus seven of 300 (2.3%) of children six months or older (P epilepsy presentation (focal, generalized, mixed/uncertain). Between the first and second treatment choices, 367 (74%) of children received levetiracetam within the first year after diagnosis. Without any specific effort, the pediatric epilepsy community has developed an unexpectedly consistent approach to initial treatment selection for early-life epilepsy. This suggests that a standard practice is emerging and could be utilized as a widely acceptable basis of comparison in future drug studies. Copyright © 2017 Elsevier Inc. All rights reserved.

    Convulsive status epilepticus (CSE) is the most common life-threatening neurological emergency in childhood. These children are also at risk of significant morbidity, with acute and chronic impact on the family and the health and social care systems. The current recommended first-choice, second-line treatment in children aged 6 months and above is intravenous phenytoin (fosphenytoin in the USA), although there is a lack of evidence for its use and it is associated with significant side effects. Emerging evidence suggests that intravenous levetiracetam may be effective as a second-line agent for CSE, and fewer adverse effects have been described. This trial therefore aims to determine whether intravenous phenytoin or levetiracetam is more effective, and safer, in treating childhood CSE. This is a phase IV, multi-centre, parallel group, randomised controlled, open-label trial. Following treatment for CSE with first-line treatment, children with ongoing seizures are randomised to receive either phenytoin (20 mg/kg, maximum 2 g) or levetiracetam (40 mg/kg, maximum 2.5 g) intravenously. The primary outcome measure is the cessation of all visible signs of CSE as determined by the treating clinician. Secondary outcome measures include the need for further anti-seizure medications or rapid sequence induction for ongoing CSE, admission to critical care areas, and serious adverse reactions. Patients are recruited without prior consent, with deferred consent sought at an appropriate time for the family. The primary analysis will be by intention-to-treat. The primary outcome is a time to event outcome and a sample size of 140 participants in each group will have 80% power to detect an increase in CSE cessation rates from 60% to 75%. Our total sample size of 308 randomised and treated participants will allow for 10% loss to follow-up. This clinical trial will determine whether phenytoin or levetiracetam is more effective as an intravenous second-line agent for CSE, and

    Full Text Available Oral phenobarbital and imepitoin in particular, followed by potassium bromide and levetiracetam are likely to be effective for the treatment of canine idiopathic epilepsy. There is strong evidence supporting the use of oral phenobarbital and imepitoin as ‘first line’ medications. However, there remains a lack of evidence for targeted treatment for the various individual epileptic phenotypes and quite limited evidence on direct comparisons of the efficacy between various anti-epileptic drugs.

    Levetiracetam (LEV) is a common add-on antiepileptic drug (AED) in dogs with refractory seizures. Concurrent phenobarbital administration alters the disposition of LEV in healthy dogs. To evaluate the pharmacokinetics of LEV in dogs with epilepsy when administered concurrently with conventional AEDs. Eighteen client-owned dogs on maintenance treatment with LEV and phenobarbital (PB group, n = 6), LEV and bromide (BR group, n = 6) or LEV, phenobarbital and bromide (PB-BR group, n = 6). Prospective pharmacokinetic study. Blood samples were collected at 0, 1, 2, 4, and 6 hours after LEV administration. Plasma LEV concentrations were determined by high-pressure liquid chromatography. To account for dose differences among dogs, LEV concentrations were normalized to the mean study dose (26.4 mg/kg). Pharmacokinetic analysis was performed on adjusted concentrations, using a noncompartmental method, and area-under-the-curve (AUC) calculated to the last measured time point. Compared to the PB and PB-BR groups, the BR group had significantly higher peak concentration (Cmax ) (73.4 ± 24.0 versus 37.5 ± 13.7 and 26.5 ± 8.96 μg/mL, respectively, P phenobarbital in dogs.

    Although generalized convulsive status epilepticus (GCSE) is a life-threatening emergency, evidence-based data to guide initial drug treatment choices are lacking in the Chinese population. We conducted this prospective, randomized, controlled trial to evaluate the relative efficacy and safety of intravenous phenobarbital and valproate in patients with GCSE. After the failure of first-line diazepam treatment, Chinese adult patients with GCSE were randomized to receive either intravenous phenobarbital (standard doses, low rate) or valproate (standard). Successful treatment was considered when clinical and electroencephalographic seizure activity ceased. Adverse events following treatment, as well as the neurological outcomes at discharge and 3 months later, were also evaluated. Overall, 73 cases were enrolled in the study. Intravenous phenobarbital was successful in 81.1% of patients, and intravenous valproate was successful in 44.4% of patients (p phenobarbital (6.7%) was significantly lower than that in patients receiving valproate (31.3%), and the total number of adverse events did not differ significantly between the two groups (p > 0.05). In the phenobarbital group, two patients (5.4%) required ventilation and two patients (5.4%) developed serious hypotension. The neurological outcomes of the phenobarbital group were generally better than those of the valproate group; however, no significant differences were observed between phenobarbital and valproate with respect to mortality (8.1 vs. 16.6%) at discharge, or mortality (16.2 vs. 30.5%) and post-symptomatic epilepsy (26.3 vs. 42.8%) at 3-month follow-up. Intravenous phenobarbital appears to be more effective than intravenous valproate for Chinese adult patients with GCSE. The occurrence of serious respiratory depression and hypotension caused by phenobarbital was reduced by decreasing the intravenous infusion rate; however, even at a lower infusion rate than typically used in other institutions, intravenous

    One-third of patients with epilepsy are resistant to anti-epileptic drugs (AEDs). Drug-resistant epilepsy is believed to be multifactorial involving both genetic and non-genetic factors. Genetic variations in the ABCB1 gene encoding the drug efflux transporter, p-glycoprotein (p-gp), may influence the interindividual variability in AED response by limiting drugs from reaching their target. Phenobarbital (PB), one of the most cost-effective and widely used AEDs in developing countries, has been reported to be transported by p-gp. This study aimed to investigate the association of a genetic variant, ABCB1 3435C>T, and non-genetic factors with phenobarbital response in Thai patients with epilepsy. One hundred and ten Thai patients with epilepsy who were treated with PB maintenance doses were enrolled in this study. Two phenotypic groups, PB-responsive epilepsy and PB-resistant epilepsy, were defined according to the International League Against Epilepsy (ILAE) criteria. Subjects were genotyped for ABCB1 3435C>T (rs1045642). Multiple logistic regression analysis was tested for the association of ABCB1 3435C>T polymorphism and non-genetic factors with PB response. Sixty-two PB-responsive epilepsy subjects and 48 PB-resistant epilepsy subjects were identified. All genotype frequencies of the ABCB1 3435C>T SNP were consistent with the Hardy-Weinberg equilibrium (P > 0·05). The ABCB1 3435C>T polymorphism and type of epilepsy were associated with response to PB. Patients with PB-resistant epilepsy had a significantly higher frequency of ABCB1 3435CC genotype and had focal epilepsy more often than patients with PB-responsive epilepsy (adjusted OR = 3·962, 95% CI = 1·075-14·610, P-value = 0·039; adjusted OR = 5·936, 95% CI = 2·272-15·513, P-value phenobarbital. © 2015 John Wiley & Sons Ltd.

    Neonatal seizures constitute the most frequent presenting neurologic sign encountered in the neonatal intensive care unit. Despite limited efficacy and safety data, phenobarbital continues to be used near-universally as the first-line anti-seizure drug (ASD) in neonates. The choice of second-line ASDs varies by provider and institution, and is still not supported by sufficient scientific evidence. In this review, we discuss the available evidence supporting the efficacy, mechanism of action, potential adverse effects, key pharmacokinetic characteristics such as interaction with therapeutic hypothermia, logistical issues, and rationale for use of neonatal ASDs. We describe the widely used neonatal ASDs, namely phenobarbital, phenytoin, midazolam, and levetiracetam, in addition to potential ASDs, including lidocaine, topiramate, and bumetanide.

    Full Text Available Phenobarbital is an antiepileptic drug that is widely used to treat epilepsy in a clinical setting. However, a long term of phenobarbital administration in pregnant women may produce side effects on embryonic skeletogenesis. In this study, we aim to investigate the mechanism by which phenobarbital treatment induces developmental defects in long bones. We first determined that phenobarbital treatment decreased chondrogenesis and inhibited the proliferation of chondrocytes in chick embryos. Phenobarbital treatment also suppressed mineralization in both in vivo and in vitro long bone models. Next, we established that phenobarbital treatment delayed blood vessel invasion in a cartilage template, and this finding was supported by the down-regulation of vascular endothelial growth factor in the hypertrophic zone following phenobarbital treatment. Phenobarbital treatment inhibited tube formation and the migration of human umbilical vein endothelial cells. In addition, it impaired angiogenesis in chick yolk sac membrane model and chorioallantoic membrane model. In summary, phenobarbital exposure led to shortened lengths of long bones during embryogenesis, which might result from inhibiting mesenchyme differentiation, chondrocyte proliferation, and delaying mineralization by impairing vascular invasion.

    CONTEXT: The optimal pharmacologic treatment for early convulsive status epilepticus is unclear. OBJECTIVE: To analyze efficacy, tolerability and safety data for anticonvulsant treatment of children and adults with convulsive status epilepticus and use this analysis to develop an evidence-based treatment algorithm. DATA SOURCES: Structured literature review using MEDLINE, Embase, Current Contents, and Cochrane library supplemented with article reference lists. STUDY SELECTION: Randomized controlled trials of anticonvulsant treatment for seizures lasting longer than 5 minutes. DATA EXTRACTION: Individual studies were rated using predefined criteria and these results were used to form recommendations, conclusions, and an evidence-based treatment algorithm. RESULTS: A total of 38 randomized controlled trials were identified, rated and contributed to the assessment. Only four trials were considered to have class I evidence of efficacy. Two studies were rated as class II and the remaining 32 were judged to have class III evidence. In adults with convulsive status epilepticus, intramuscular midazolam, intravenous lorazepam, intravenous diazepam and intravenous phenobarbital are established as efficacious as initial therapy (Level A). Intramuscular midazolam has superior effectiveness compared to intravenous lorazepam in adults with convulsive status epilepticus without established intravenous access (Level A). In children, intravenous lorazepam and intravenous diazepam are established as efficacious at stopping seizures lasting at least 5 minutes (Level A) while rectal diazepam, intramuscular midazolam, intranasal midazolam, and buccal midazolam are probably effective (Level B). No significant difference in effectiveness has been demonstrated between intravenous lorazepam and intravenous diazepam in adults or children with convulsive status epilepticus (Level A). Respiratory and cardiac symptoms are the most commonly encountered treatment-emergent adverse events

    Pressure ulcers are common in clinical practice and pose a significant health problem worldwide. Apart from causing suffering to patients, they also result in longer hospital stays and increase the cost of health care. A variety of methods are used for treating pressure ulcers, including pressure relief, patient repositioning, biophysical strategies, nutritional supplementation, debridement, topical negative pressure, and local treatments including dressings, ointments and creams such as bacitracin, silver sulphadiazine, neomycin, and phenytoin. Phenytoin is a drug more commonly used in the treatment of epilepsy, but may play an important role in accelerating ulcer healing. To assess the effects of topical phenytoin on the rate of healing of pressure ulcers of any grade, in any care setting. In September 2016, we searched the following electronic databases to identify relevant randomized clinical trials: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library); Ovid MEDLINE; Ovid Embase; and EBSCO CINAHL Plus. We handsearched conference proceedings from the European Pressure Ulcer Advisory Panel, European Wound Management Association and the Tissue Viability Society for all available years. We searched the references of the retrieved trials to identify further relevant trials. We also searched clinical trials registries to identify ongoing and unpublished studies. There were no restrictions with respect to language, date of publication or study setting. We included all randomized controlled trials (RCTs) addressing the effects (both benefits and harms) of topical phenytoin on the healing of pressure ulcers of any grade compared with placebo or alternative treatments or no therapy, irrespective of blinding, language, and publication status. Two review authors independently selected studies, extracted information on participants, interventions, methods and results and assessed risk of bias using

    Status epilepticus is the most severe form of epilepsy, with a high mortality rate and high health care costs. Status epilepticus is divided into four stages: early, established, refractory, and super-refractory. While initial treatment with benzodiazepines has become standard of care for early status epilepticus, treatment after benzodiazepine failure (established status epilepticus (ESE)) is incompletely studied. Effective treatment of ESE is critical as morbidity and mortality increases dramatically the longer convulsive status epilepticus persists. Phenytoin/fosphenytoin, valproic acid, levetiracetam, phenobarbital, and lacosamide are the most frequently prescribed antiseizure medications for treatment of ESE. To date there are no class 1 data to support pharmacologic recommendations of one agent over another. We review each of these medications, their pharmacology, the scientific evidence in support and against each in the available literature, adverse effects and safety profiles, dosing recommendations, and limitations of the available evidence. We also discuss future directions including the established status epilepticus treatment trial (ESETT). Substantial further research is urgently needed to identify these patients (particularly those with non-convulsive status epilepticus), elucidate the most efficacious antiseizure treatment with head-to-head randomized prospective trials, and determine whether this differs for convulsive vs. non-convulsive ESE.

    Barbiturates and benzodiazepines are the first-line anticonvulsants for neonatal seizures. However, in immature brains, those drugs may lead to paradoxical neuronal excitation. A patient with benign familial neonatal epilepsy developed epileptic encephalopathy after massive doses of phenobarbital that were followed by a continuous infusion of midazolam on postnatal day 3. Electroencephalography revealed rhythmic delta activity in clusters with migrating epileptic foci. After discontinuation of both drugs, the patient's consciousness promptly improved and her electroencephalography normalized on postnatal day 5. This baby developed persistent electroencephalographic seizures due to massive doses of phenobarbital and midazolam. Clinicians should be aware of this anticonvulsant-induced paradoxical neuronal excitation and the uncoupling phenomenon, especially in individuals with benign familial neonatal epilepsy, who have low seizure thresholds.

    A simple and efficient bioanalytical method for simultaneous determination of phenobarbital (PB), phenytoin (PHT), carbamazepine (CBZ), and its active metabolite carbamazepine 10,11-epoxide (CBZE) in human plasma using online solid phase extraction (SPE)-liquid chromatography (LC) coupled with high resolution mass spectrum (HRMS) under targeted MS/MS (t-MS(2)) analysis mode has been developed. The procedure integrated an automated sample clean-up of human plasma by Oasis®HLB SPE cartridge, a separation by ZORBAX SB-C18 analysis column, and a quantification by Q-Exactive Hybrid Quadrupole-Orbitrap. The total running time was 13min. The lower limit of quantification (LLOQ) of PB, PHT, CBZ, and CBZE were 0.008, 0.008, 0.0016 and 0.0016μgmL(-1) respectively and the linearities were in the range of 0.008-2.500, 0.008-2.500, 0.0016-0.500 and 0.0016-0.500μgmL(-1) respectively. The mean recovery was between 91.82% and 108.27% and the matrix effect was between 93.29% and 102.09%. The relative standard deviations of interday and intraday were less than 6.41%. The method has been successfully applied in therapeutic drug monitoring (TDM) of four Chinese epilepsy patients. This fully automated, simple, sensitive and reliable online-SPE-LC-HRMS/MS method serves well for TDM of PB, PHT, CBZ and CBZE at clinics for either single or combination treatment.

    Intravenous phenobarbital (IV-PB) therapy was launched in Japan in October 2008. We retrospectively investigated its efficacy and tolerability in patients with status epilepticus. Forty-three consecutive patients received IV-PB for status epilepticus between June 2009 and April 2011. Among them, 39 patients had underlying diseases, which included acute diseases in 19 patients and chronic conditions in 20 patients. Although 18 patients had been taking antiepileptic drugs (AEDs) before the occurrence of status epilepticus, the blood AED concentrations in 8 patients was below the therapeutic levels. Before the administration of IV-PB, 39 patients were treated with intravenous benzodiazepine, 17 patients were treated with intravenous phenytoin, and 15 patients with intravenous infusion of lidocaine. The initial doses of IV-PB ranged from 125 to 1,250 mg (1.9-20.0 mg/kg). Additional doses of IV-PB were required in 12 patients. Seizures were controlled in 35 patients (81%) after IV-PB administration. Cessation of status epilepticus was attained in 24 patients after the initial dose and in 11 patients after additional doses. There were no serious adverse effects, although respiratory suppression was observed in 3 patients and drug eruption was observed in 1 patient. IV-PB is relatively safe and effective for controlling status epilepticus. If the first dose is not effective, additional doses are required up to the recommended maximum dose.

    Imepitoin has recently been approved in Europe for the management of dogs with idiopathic epilepsy. Currently, there is no evidence-based information available on the efficacy of antiepileptic drugs used as additions to the therapeutic regimen in dogs with idiopathic epilepsy that are not well controlled with imepitoin. The goal of this study was to evaluate the efficacy of phenobarbital or potassium bromide (KBr) as add-on antiepileptic drugs for controlling dogs refractory to a maximum dose of imepitoin (30 mg/kg twice daily). The study was performed as a prospective, randomised, controlled clinical trial. The efficacy of phenobarbital and KBr was evaluated by comparing monthly seizure frequency (MSF), monthly seizure day frequency (MSDF), the presence of cluster seizures during a retrospective 2-month period with a prospective follow-up of 6 months, and the overall responder rate. Twenty-seven dogs were included in the study, 14 dogs in the phenobarbital group and 13 dogs in the KBr group. Both median MSF and MSDF decreased in the phenobarbital group (both P = 0.001) and in the KBr group (P = 0.004 and P = 0.003, respectively). Overall, the number of dogs with cluster seizures decreased (P = 0.0005). The responder rate was 79% vs. 69% in the phenobarbital and KBr groups, respectively. We conclude that phenobarbital or KBr add-on treatment decreases median MSF and MSDF in epileptic dogs refractory to a maximum dose of imepitoin. Combination therapy was generally well tolerated and resulted in an improvement in seizure management in the majority of the dogs. Copyright © 2017 Elsevier Ltd. All rights reserved.

    This is the third of three papers that summarize the second symposium on Transition in Epilepsies held in Paris in June 2016. This paper focuses on treatment issues that arise during the course of childhood epilepsy and make the process of transition to adult care more complicated. Some AEDs used during childhood, such as stiripentol, vigabatrin, and cannabidiol, are unfamiliar to adult epilepsy specialists. In addition, new drugs are being developed for treatment of specific childhood onset epilepsy syndromes and have no indication yet for adults. The ketogenic diet may be effective during childhood but is difficult to continue in adult care. Regional adult epilepsy diet clinics could be helpful. Polytherapy is common for patients transitioning to adult care. Although these complex AED regimes are difficult, they are often possible to simplify. AEDs used in childhood may need to be reconsidered in adulthood. Rescue medications to stop prolonged seizures and clusters of seizures are in wide home use in children and can be continued in adulthood. Adherence/compliance is notoriously difficult for adolescents, but there are simple clinical approaches that should be helpful. Mental health issues including depression and anxiety are not always diagnosed and treated in children and young adults even though effective treatments are available. Attention deficit hyperactivity disorder and aggressive behavior disorders may interfere with transition and successful adulthood but these can be treated. For the majority, the adult social outcome of children with epilepsy is unsatisfactory with few proven interventions. The interface between pediatric and adult care for children with epilepsy is becoming increasingly complicated with a need for more comprehensive transition programs and adult epileptologists who are knowledgeable about special treatments that benefit this group of patients.

    Full Text Available Achievement of seizure free is the ultimate goal of patients with epilepsy. Lifelong treatment may be needed in some epileptic children, especially in those with intractable epilepsy. To be more realistic, this goal may be modified to reduce the frequency of more disabling types of seizures. Chronic seizures influence children in social activities, psychology,cognition as well as many other aspects. Therefore, their long-term management requires concerted lifelong care of pediatricians, neurologists and social workers. During the course of treatment, doctors should evaluate the patients regularly, prevent and control the side effects of antiepileptic drugs (AEDs and monitor patients for AEDs-associated adverse events. In addition, doctors should choose the optimal therapeutic regimen for patients with refractory epilepsy, and achieve a balance between benefit and risk in order to improve the quality of life of patients.

    There are many theories explaining vitiligo such as genetic, autoimmune, neural, free radicals, biochemical, intrinsic defect, melanocytorrhagy, and convergent theories. Phenytoin is a widely used anticonvulsant, which is used in cutaneous medicine for treatment of ulcers and epidermolysis bullosa. The aim of this study is to assess the effectiveness of topical phenytoin gel in the treatment of vitiligo patients and explaining the underlying mechanism using immunohistochemistry for evaluation of HMB45, CD4, and CD8. Only 9 patients out of 28 experienced response to phenytoin in the form of dull, white color change and light brown color. Post-phenytoin treatment biopsies showed decreased density of inflammation, increased melanin and increased HMB45 positive cells together with an increased number of CD4 positive lymphocytes and decreased number of CD8 positive lymphocytes. These observations did not reach significant level (P > 0.05). A high percentage of CD4 positive lymphocytes was significantly associated with a long duration of vitiligo (p = 0.03) and segmental vitiligo type (p = 0.02). The current study applied phenytoin as 2% concentrated gel for 3 months, which is a relatively short duration without observed side effects throughout the period. These results indicate that topical phenytoin of low concentrations may have beneficial effects through immunomodulatory activity by affecting CD4 and CD8 counts and subsequently the ratio between them. Further studies are recommended to combine phenytoin with other antivitiligo agents as local corticosteroids or phototherapy to clarify if it could potentiate their effects.

    Anticonvulsant drugs, when given during vulnerable periods of brain development, can have long-lasting consequences on nervous system function. In rats, the second postnatal week approximately corresponds to the late third trimester of gestation/early infancy in humans. Exposure to phenobarbital during this period has been associated with deficits in learning and memory, anxiety-like behavior, and social behavior, among other domains. Phenobarbital is the most common anticonvulsant drug used in neonatology. Several other drugs, such as lamotrigine, phenytoin, and clonazepam, have also been reported to trigger behavioral changes. A new generation anticonvulsant drug, retigabine, has not previously been evaluated for long-term effects on behavior. Retigabine acts as an activator of KCNQ channels, a mechanism that is unique among anticonvulsants. Here, we examined the effects retigabine exposure from postnatal day (P)7 to P14 on behavior in adult rats. We compared these effects with those produced by phenobarbital (as a positive control) and saline (as a negative control). Motor behavior was assessed by using the open field and rotarod, anxiety-like behavior by the open field, elevated plus maze, and light-dark transition task, and learning/memory by the passive avoidance task; social interactions were assessed in same-treatment pairs, and nociceptive sensitivity was assessed via the tail-flick assay. Motor behavior was unaltered by exposure to either drug. We found that retigabine exposure and phenobarbital exposure both induced increased anxiety-like behavior in adult animals. Phenobarbital, but not retigabine, exposure impaired learning and memory. These drugs also differed in their effects on social behavior, with retigabine-exposed animals displaying greater social interaction than phenobarbital-exposed animals. These results indicate that neonatal retigabine induces a subset of behavioral alterations previously described for other anticonvulsant drugs and extend

    In low- and middle-income countries (LMICs), a large proportion of people with epilepsy do not receive treatment. An analysis of the availability, price, and affordability of antiepileptic drugs (AEDs) was conducted to evaluate whether these factors contribute to the treatment gap. Data for five AEDs (phenytoin, carbamazepine, valproic acid, phenobarbital, and diazepam) were obtained from facility-based surveys conducted in 46 countries using the World Health Organization/Health Action International (WHO/HAI) methodology. Outcome measures were percentage availability, ratios of local prices to international reference prices, and number of days' wages needed by the lowest-paid unskilled government worker to purchase treatment. Prices were adjusted for inflation/deflation and purchasing power parity. The average availability of generic AEDs in the public sector was Private sector availability of generic oral AEDs ranged from 42.2% for phenytoin to 69.6% for phenobarbital. Public sector patient prices for generic carbamazepine and phenytoin were 4.95 and 17.50 times higher than international reference prices, respectively, whereas private sector patient prices were 11.27 and 24.77 times higher, respectively. For both medicines, originator brand prices were about 30 times higher. The highest prices were observed in the lowest income countries. The lowest-paid government worker would need wages from 1-2.6 days' to purchase a month's supply of phenytoin, whereas carbamazepine would cost 2.7-16.2 days' wages. Despite its widespread use in LMICs, WHO/HAI survey data for phenobarbital was only available from a small number of countries. In LMICs, availability and affordability of AEDs are poor and may be acting as a barrier to accessing treatment for epilepsy. Ensuring a consistent supply of AEDs at an affordable price should be a priority. Wiley Periodicals, Inc. © 2012 International League Against Epilepsy.

    Estimated prevalence of canine idiopathic epilepsy is 0.6 per cent in the first-opinion canine population in the UK. Phenobarbital monotherapy has been reported to reduce/eradicate seizure activity in 60-93 per cent of idiopathic epileptic dogs (IEDs). The objective of this study was to evaluate safety and efficacy of the administration of phenobarbital orally every eight hours in IEDs with phenobarbital elimination half-life less than 20 hours. Medical records of 10 IEDs in which steady state trough serum phenobarbital levels were within the reference range and phenobarbital elimination half-life had become less than 20 hours following prolonged administration every 12 hours were reviewed. Side effects and seizure frequency when phenobarbital was administered every 12 hours or 8 hours were compared. In all dogs the side effects of the antiepileptic medication treatment improved. When phenobarbital was administered every eight hours, 9/10 dogs experienced improvement in seizure frequency and 8/10 dogs maintained seizure freedom for a period three times longer than the longest interictal interval period previously recorded. Reduction in the severity and number of clusters of seizures was recorded in one of the remaining two dogs. The administration of phenobarbital orally every eight hours in IEDs with decreased phenobarbital elimination half-life appears safe and can improve seizure management.

    Full Text Available Objective. Herbal medicine has been widely used to treat drug resistant epilepsy. Shihogyejitang (SGT has been commonly used to treat epilepsy. We investigated the effect and safety of SGT in children with drug resistant epilepsy. Design. We reviewed medical records of 54 patients with epilepsy, who failed to respond to at least two antiepileptic drugs and have been treated with SGT between April 2006 and June 2014 at the Department of Pediatric Neurology, I-Tomato Hospital, Korea. Effect was measured by the response rate, seizure-free rate, and retention rate at six months. We also checked adverse events, change in antiepileptic drugs use, and the variables related to the outcome. Results. Intent-to-treat analysis showed that, after six months, 44.4% showed a >50% seizure reduction, 24.1% including seizure-free, respectively, and 53.7% remained on SGT. Two adverse events were reported, mild skin rash and fever. Focal seizure type presented significantly more positive responses when compared with other seizure types at six months (p=0.0284, Fisher’s exact test. Conclusion. SGT is an effective treatment with excellent tolerability for drug resistant epilepsy patients. Our data provide evidence that SGT may be used as alternative treatment option when antiepileptic drug does not work in epilepsy children.

    The aim of this study was to determine the complementary and alternative approaches used by parents of children with epilepsy on epilepsy management. This descriptive study included a total of 304 parents of children with epilepsy aged between 0 and 18years evaluated at the Pediatric Neurology Clinic of Akdeniz University Hospital in Turkey between January and May 2013. Data were collected by using a questionnaire developed by the researchers. It was determined that all the parents use complementary and alternative approaches for their children with epilepsy, and the most common approaches are praying (99.3%); keeping their children away from the effects of smoking (79.8%); feeding their children walnuts (79.6%), butter (59.2%), and bone marrow (58.6%); providing their children with good quality sleep (58.6%); and enabling their children to play games (51%). The approaches commonly applied during seizures include praying (96.2%), comforting their children in their arms and showing affection (55.6%), waiting for seizures to finish at home (45.7%), and laying children on their side (41.1%). Of parents, 98% stated that alternative approaches enable them to control their child's seizures, 100% said that alternative approaches have no adverse effect, and 98.4% stated that they will continue to use these approaches. The children's approaches to cope with epilepsy included looking after pets (72.7%), listening to music (70.1%), watching television (64.5%), playing games (55.3%), praying (51%), and spending time with friends (48.7%). Most of the approaches used by parents and children with epilepsy for the management of illness are determined to consist of complementary approaches that may contribute to management of epilepsy. Knowing the approaches of parents and children with epilepsy that could adversely affect disease management is important for educating parents and children to avoid these potentially harmful interventions.

  15. The effect of antiepileptic drugs on cognitive functions

    Directory of Open Access Journals (Sweden)

    A. S. Kotov

    2013-01-01

    Full Text Available Impaired cognitive function is a common problem in epileptic patients. The exact cause of cognitive impairment in case of epilepsy has not been explored fully, but there is no doubt that a role in this is played by three factors: the disease underlying epilepsy; epileptic seizures proper; and negative side effects of antiepileptic drugs. Their cognitive effects are one of the major problems affecting the tolerance of therapy. The review considers the effects of phenobarbital, phenytoin, carbamazepine, valproates, oxcarbazepine, topiramate, lamotrigine, and levetiracetam in terms of their action on the cognitive function of healthy volunteers and epileptic patients.

    Low frequency stimulation (LFS) has been proposed as a new approach in the treatment of epilepsy. The anticonvulsant mechanism of LFS may be through its effect on GABAA receptors, which are the main target of phenobarbital anticonvulsant action. We supposed that co-application of LFS and phenobarbital may increase the efficacy of phenobarbital. Therefore, the interaction of LFS and phenobarbital on GABAergic inhibitory post-synaptic currents (IPSCs) in kindled and control rats was investigated. Animals were kindled by electrical stimulation of basolateral amygdala in a semi rapid manner (12 stimulations/day). The effect of phenobarbital, LFS and phenobarbital+LFS was investigated on GABAA-mediated evoked and miniature IPSCs in the hippocampal brain slices in control and fully kindled animals. Phenobarbital and LFS had positive interaction on GABAergic currents. In vitro co-application of an ineffective pattern of LFS (100 pulses at afterdischarge threshold intensity) and a sub-threshold dose of phenobarbital (100μM) which had no significant effect on GABAergic currents alone, increased the amplitude and area under curve of GABAergic currents in CA1 pyramidal neurons of hippocampal slices significantly. Interestingly, the sub-threshold dose of phenobarbital potentiated the GABAergic currents when applied on the hippocampal slices of kindled animals which received LFS in vivo. Post-synaptic mechanisms may be involved in observed interactions. Obtained results implied a positive interaction between LFS and phenobarbital through GABAA currents. It may be suggested that a combined therapy of phenobarbital and LFS may be a useful manner for reinforcing the anticonvulsant action of phenobarbital. Copyright © 2016 IBRO.

    Television as an external stimulation can precipitate epileptic seizures. Today this kind of epilepsy is known as television epilepsy. As children spend much of their time watching television, it is important to study this type of epilepsy in this age group. This study was designed to describe the clinical and some demographic characteristics of television epilepsy in Iranian children. Patients who were diagnosed as having television epilepsy with an age less than 12 years were recruited from outpatient neurology clinics in Isfahan, Iran, from September 2002 through September 2006. We collected the case-related information including electroencephalograms, radiologic findings, and patients' history. Thirty patients with television epilepsy with the age less than 12 years were identified. Of whom 17 (56.7%) were females and 13 (43.3%) were males. The mean age at the onset of seizure was 9.9+/-2.1 years. Children had absence (3.3%), myoclonic (3.3%), and generalized tonic-clonic (93.3+/-) seizures in response to intermittent photic stimulations. Interictal epileptiform discharges in electroencephalograms were detected in 83.3%. In addition, neuroimaging findings were normal in 96.7% of the patients. In our study, 56.7% of the children had pure television epilepsy and 43.3% experienced other types of generalized seizure. During the follow-up period after initiation of variable drug treatments including valproic acid, carbamazepine, phenobarbital, clonazepam, ethosuximide, and lamotrigine all the patients had complete seizure remission. The clinical and demographic differences of our patients compared with other reports are probably due to genetic differences. In our study, it was demonstrated that carbamazepine could be used in children with television epilepsy because it had successfully terminated seizures in 43.3% of the patients.

    Full Text Available Phenytoin is an effective antiepileptic drug, although, it can be associated with many side effects, including dyskinesia. OBJECTIVE: To describe the clinical characteristics of phenytoin induced dyskinesia. METHODS: We investigated the occurrence of involuntary movements in patients followed at our adult and pediatric epilepsy clinics during the period of one year. RESULTS: Three patients presented with phenytoin-induced dyskinesia: one adult with axial and orofacial dyskinesia, and two children with choreoathetosis. They did not have other signs of phenytoin intoxication and had complete recovery after phenytoin withdrawal. CONCLUSION: Phenytoin induced dyskinesia may occur during either chronic or initial treatment and with normal serum phenytoin levels. However, it occurs most often in patients on polytherapy, usually after increasing dosage and with toxic serum levels. Other signs of phenytoin intoxication may be present in these patients, but often the dyskinesia is the only side effect, which may delay the diagnosis and treatment. The clinical characteristics of the involuntary movements vary and may be focal or generalized, most often characterized by choreoathetosis and dyskinesias. These may last for hours, days or even years, but frequently disappear completely after phenytoin withdrawal.Fenitoína é droga anti-epiléptica eficaz, mas pode estar associada a vários efeitos colaterais, inclusive discinesia. OBJETIVO: Descrever as características clínicas da discinesia induzida por fenitoína. MÉTODO: Avaliamos a ocorrência de movimentos involuntários em pacientes seguidos nos ambulatórios de epilepsia durante o período de um ano. RESULTADOS: Três pacientes apresentaram discinesia induzida por fenitoína: um adulto com discinesia orofacial e duas crianças com coreoatetose. Eles não tinham outros sinais de intoxicação por fenitoína e apresentaram recuperação completa após a retirada da fenitoína. CONCLUSÃO: Discinesia

    Anxiety disorders are prevalent in children with epilepsy. The purpose of this study was to evaluate the efficacy, adaptability, and feasibility of a manual-based, computer-assisted cognitive behavioral therapy (CBT) intervention for anxiety disorders in children with epilepsy. Fifteen anxious youth (aged 8-13 years) with epilepsy completed 12 weeks of manualized computer-assisted CBT. The children and parents completed a semi-structured interview at baseline, and questionnaires assessing symptoms of anxiety, depression, and behavior problems were completed prior to treatment, at treatment midpoint, after treatment completion, and at three months posttreatment. There were significant reductions in the symptoms of anxiety and depression reported by the children at completion of the intervention and at the three-month follow-up. Similarly, the parents reported fewer symptoms of anxiety and a reduction in behavior problems. No adverse events were reported. This CBT intervention for children with epilepsy and anxiety disorders appears to be safe, effective, and feasible and should be incorporated into future intervention studies.

    Full Text Available Abstract Background The choice of antiepileptic drug for an individual should be based upon the highest quality evidence regarding potential benefits and harms of the available treatments. Systematic reviews and meta-analysis of randomised controlled trials should be a major source of evidence supporting this decision making process. We summarise all available individual patient data evidence from randomised controlled trials that compared at least two out of eight antiepileptic drugs given as monotherapy. Methods Multiple treatment comparisons from epilepsy monotherapy trials were synthesized in a single stratified Cox regression model adjusted for treatment by epilepsy type interactions and making use of direct and indirect evidence. Primary outcomes were time to treatment failure and time to 12 month remission from seizures. A secondary outcome was time to first seizure. Results Individual patient data for 6418 patients from 20 randomised trials comparing eight antiepileptic drugs were synthesized. For partial onset seizures (4628 (72% patients, lamotrigine, carbamazepine and oxcarbazepine provide the best combination of seizure control and treatment failure. Lamotrigine is clinically superior to all other drugs for treatment failure but estimates suggest a disadvantage compared to carbamazepine for time to 12 month remission [Hazard Ratio (95% Confidence Interval = 0.87(0.73 to 1.04] and time to first seizure [1.29(1.13 to 1.48]. Phenobarbitone may delay time to first seizure [0.77(0.61 to 0.96] but at the expense of increased treatment failure [1.60(1.22 to 2.10]. For generalized onset tonic clonic seizures (1790 (28% patients estimates suggest valproate or phenytoin may provide the best combination of seizure control and treatment failure but some uncertainty remains about the relative effectiveness of other drugs. Conclusion For patients with partial onset seizures, results favour carbamazepine, oxcarbazepine and lamotrigine. For

  2. Stimulation of prostacyclin synthesis in rats by phenobarbital treatment

    Prostacyclin (PGI 2 ), synthesized in the endothelial cells of arteries, is known to inhibit the aggregation of platelets and hence thrombosis in blood. Low levels of PGI 2 have been observed in coronary heart disease which is associated with low levels of HDL in blood. Recently, it has been shown that synthesis of PGI 2 in vitro, is stimulated by HDL. Hence it seems likely that higher level of HDL in blood would increase the level of PGI 2 in blood. Since phenobarbital treatment is known to increase blood HDL levels in humans and animals, this study was undertaken to determine the effect of phenobarbital treatment on the synthesis of PGI 2 . Coronary vascular microsomes were prepared from Sprague Dawley rats treated with phenobarbital for two days. The PGI 2 synthesizing activity was assayed by incubating these microsomes with 1- 14 C-arachidonic acid and by determining the 14 C-activity recovered in 6-ketoprostaglandin F/sub 1α/, the stable decomposition product of PGI 2 . Phenobarbital treatment increased the synthesis of PGI 2 nearly 2-fold. Addition of phenobarbital did not increase PGI 2 synthesis in control microsomes; however, the synthesis was increased by HDL. Thus, it appears that the observed increase in PGI 2 synthesis resulting from phenobarbital treatment was partly, if not totally, due to the increase in blood HDL level

    Full Text Available Epilepsy is the most common neurological disorder affecting approximately 50 million people worldwide. In India, overall prevalence of epilepsy is reported to be 5.59/1000 population. Antiepileptic drugs (AEDs constitute the main-stay of treatment with a large number of AEDs available in the market. High incidence of adverse effects is a major limitation with AEDs. One of the major concerns is significant metabolic effects on the bone. However, little attention has been paid to this issue because most of the bone effects remain subclinical for a long time and may take years to manifest clinically. The main effects include hypocalcemia, hypophosphatemia, reduced serum levels of Vitamin D, increase in parathormone (PTH levels, and alterations in bone turnover markers. The CYP450 enzyme-inducing AEDs such as phenytoin, phenobarbital, carbamazepine, and primidone are the most common AEDs associated with bone disorders while the data regarding the effect of valproate and newer AEDs such as lamotrigine, gabapentin, vigabatrin, levetiracetam, and topiramate on bone metabolism and bone density are scanty and controversial. Deficiency of Vitamin D is commonly described as a cause for the bone loss in epileptic patients while others being decreased absorption of calcium, increased PTH levels, and inhibition of calcitonin secretion, etc. However, there are no formal practical guidelines for the management of bone disease among those taking AEDs. Evidence-based strategies regarding monitoring, prevention, and treatment of bone diseases in patients on AED therapy are needed.

  7. A review of epidemiological data on epilepsy, phenobarbital, and risk of liver cancer.

    2014-01-01

    Phenobarbital is not genotoxic, but has been related to promotion of liver cancer (as well as inhibition) in rodents. In October 2012, we carried out a systematic literature search in the Medline database and searched reference lists of retrieved publications. We identified 15 relevant papers. Epidemiological data on epileptics/anticonvulsant use and liver cancer were retrieved from eight reports from seven cohort (record linkage) studies of epileptics, and data on phenobarbital use from a pharmacy-based record linkage investigation of patients treated with phenobarbital (three reports), plus a case-control study nested in one of the cohort studies and including information on phenobarbital use. Of the studies of cancer in epileptics, two showed no excess risk of liver cancer. A long-term (1933-1984) Danish cohort study of epileptics found relative risks (RRs) of 4.7 [95% confidence interval (CI) 3.2-6.8] of liver cancer and of 2.2 (95% CI 1.2-3.5) of biliary tract cancers. Such apparent excess risks could, however, be largely or completely attributed to thorotrast, a contrast medium used in the past in epileptic patients for cerebral angiography. A Finnish cohort study of epileptics obtained an RR of 1.7 (95% CI 1.2-2.4). Such an apparent excess risk, however, was not related to phenobarbital or to any specific anticonvulsant drug. The long-term follow-up of two UK cohorts found some excess risk of liver cancer among severe, but not among mild, epileptics. Some excess risk of liver cancer was also found in cohort studies of patients hospitalized for epilepsy in Sweden and Taiwan, in the absence, however, of association with any specific drugs. A UK General Practice database, comparing epileptics treated with valproate with unexposed ones, found a very low incidence of liver cancer. Of the studies of cancer in patients treated with phenobarbital, a large US pharmacy-based cohort investigation showed no excess risk of liver cancer. In a case-control study, nested in

    2009-01-01

    Caffeine has been reported to be proconvulsant and to reduce the anticonvulsant efficacy of a variety of antiepileptic drugs (carbamazepine, phenobarbital, phenytoin, valproate and topiramate) in animal models of epilepsy and to increase seizure frequency in patients with epilepsy. Using the mouse maximal electroshock model, the present study was undertaken so as to ascertain whether caffeine affects the anticonvulsant efficacy of the new antiepileptic drugs lamotrigine, oxcarbazepine and tiagabine. The results indicate that neither acute nor chronic caffeine administration (up to 46.2 mg/kg) affected the ED(50) values of oxcarbazepine or lamotrigine against maximal electroshock. Similarly, caffeine did not modify the tiagabine electroconvulsive threshold. Furthermore, caffeine had no effect on oxcarbazepine, lamotrigine and tiagabine associated adverse effects such as impairment of motor coordination (measured by the chimney test) or long-term memory (measured by the passive avoidance task). Concurrent plasma concentration measurements revealed no significant effect on lamotrigine and oxcarbazepine concentrations. For tiagabine, however, chronic caffeine (4 mg/kg) administration was associated with an increase in tiagabine concentrations. In conclusion, caffeine did not impair the anticonvulsant effects of lamotrigine, oxcarbazepine, or tiagabine as assessed by electroconvulsions in mice. Also, caffeine was without effect upon the adverse potential of the studied antiepileptic drugs. Thus caffeine may not necessarily adversely affect the efficacy of all antiepileptic drugs and this is an important observation.

    Phenobarbital (Luminal), well known as a hypnotic agent, plays also an important role in the medical treatment of epilepsy. With the object of studying the metabolism of this medicament in the living system, the synthesis of phenobarbital marked in position 2 of the pyrimidinic ring has been effected. It has been necessary, in order to carry out to research into the metabolism of this product, to have a phenobarbital marked in position 5 of the pyrimidinic ring. This synthesis, making it possible to introduce C-14 into position 5 of the pyrimidinic ring, consists of seven stages starting from C-14 carboxyl benzoic acid having a specific activity of 25 mc/mM. The melting point of the final product is 172 - 173 deg. C and its specific activity is 11.15 mc/mM. The overall radioactive yield of the pure product, with respect to the original benzoic acid (10 mM) is of the order of 3 per cent. The purity of the product has been controlled by paper chromatography; it is of the order of 99 per cent. (author) [fr

    The anticonvulsant activity and safety of imepitoin, a novel antiepileptic drug licensed in the European Union, were evaluated in a multicentre field efficacy study as well as in a safety study under laboratory conditions. Efficacy of imepitoin was compared with phenobarbital in 226 client-owned dogs in a blinded parallel group design. The administration of imepitoin twice daily in incremental doses of 10, 20 or 30 mg/kg demonstrated comparable efficacy to phenobarbital in controlling seizures in dogs. The frequency of adverse events including somnolence/sedation, polydipsia and increased appetite was significantly higher in the phenobarbital group. In phenobarbital-treated dogs, significantly increased levels of alkaline phosphatase, gamma-glutamyl-transferase and other liver enzymes occurred, while no such effect was observed in the imepitoin group. In a safety study under laboratory conditions, healthy beagle dogs were administered 0, 30, 90 or 150 mg/kg imepitoin twice daily for 26 weeks. A complete safety evaluation including histopathology was included in the study. A no-observed-adverse-event level of 90 mg/kg twice daily was determined. These results indicate that imepitoin is a potent and safe antiepileptic drug for dogs. © 2014 The Authors. Journal of Veterinary Pharmacology and Therapeutics Published by John Wiley & Sons Ltd.

    We investigated the peripapillary retinal nerve fiber layer thickness with optical coherence tomography in epileptic children receiving valproic acid monotherapy. The study was conducted on children aged 8-16 years who were undergoing valproic acid monotherapy for epilepsy. The study group comprised a total of 40 children who met the inclusion criteria and 40 healthy age- and sex-matched children as a control group. Children with at least a 1-year history of epilepsy and taking 10-40 mg/kg/day treatment were included in the study. Peripapillary retinal nerve fiber layer thickness measurements were performed using Cirrus HD optical coherence tomography. All children and parents were informed about the study and informed consent was obtained from the parents of all the participants. The study group included 21 girls and 19 boys with a mean age of 10.6 ± 2.3 years. According to the results of optical coherence tomography measurements, the mean peripapillary retinal nerve fiber layer thickness was 91.6 ± 9.7 in the patient group and 95.5 ± 7.4 μm in the control group (P epilepsy who were receiving valproic acid monotherapy compared with healthy children. This situation can lead to undesirable results in terms of eye health. New studies are needed to investigate whether these findings are the result of epilepsy or can be attributed to valproic acid and whether there are adverse effects of valproic acid later in life.

    2018-05-01

    Full Text Available BACKGROUND: Neuropathic pain can be disabling, and is often difficult to treat. Within a year, over half of all patients stop taking their prescribed neuropathic pain medication, which is most probably due to side effects or disappointing analgesic results. Therefore, new therapies are needed to alleviate neuropathic pain. As such, topical analgesics could be a new inroad in the treatment of neuropathic pain. In 2014, we developed a new topical formulation containing either phenytoin or sodium phenytoin. After optimization of the formulation, we were able to reach a 10% concentration and combine phenytoin with other co-analgesics in the same base cream. OBJECTIVE: To describe a series of 70 neuropathic pain patients who were treated with phenytoin cream. MATERIAL AND METHODS: Cases treated with phenytoin 5% or 10% creams were gathered. The mean onset of pain relief, the duration of effect, and reduction in pain intensity measured on the 11-point numerical rating scale (NRS were all studied. A single-blind response test with phenytoin 10% and placebo creams was conducted on 12 patients in order to select responders prior to prescribing the active cream. Plasma phenytoin concentrations were measured in 16 patients. RESULTS: Nine patients applied phenytoin 5% cream, and 61 patients used phenytoin 10% cream. After grouping the effects of all of the patients, the mean onset of pain relief was 16.3 min (SD: 14.8, the mean duration of analgesia was 8.1 h (SD: 9.1, and the mean pain reduction on the NRS was 61.2% (SD: 25.0. The mean pain reduction on the NRS while using phenytoin cream was statistically significant compared with the baseline, with a reduction of 4.5 (CI: 4.0 to 5.0, p < 0.01. The 12 patients on whom a single-blind response test was performed experienced a statistically significant reduction in pain in the area where the phenytoin 10% cream was applied in comparison to the area where the placebo cream was applied (p < 0.01.

    2014-01-01

    Full Text Available Specific cognitive deficits have been identified in children with epilepsy irrespective of results on intelligence tests. Memory deficits are traditionally attributed to temporal lobe epilepsy, whereas the impact of frontal lobe epilepsy on memory functions has remained controversial. The aim of this study was the examination of memory abilities in other childhood common epilepsy syndromes (frontal lobe epilepsy (FLE, childhood absence epilepsy (CAE, and benign epilepsy with centrotemporal spikes (BECTS and the influence of epilepsy-related variables. Memory was examined in 90 children with epilepsy (each epilepsy group consisted of 30 children, aged 6–15, and compared with 30 control children. Children with FLE showed significant deficits in verbal and visual memory. In addition, type of epilepsy, earlier age at epilepsy onset, and longer active duration of epilepsy were associated with memory problems. Seizure frequency and treatment, however, did not influence memory performance. This study indicates that children with FLE show greater risk of developing memory deficits than children with CAE or BECTS, thus highlighting the importance of assessing also memory functions in frontal lobe epilepsy.

    There is evidence that certain antiepileptic drugs (AEDs) are teratogenic and are associated with an increased risk of congenital malformation. The majority of women with epilepsy continue taking AEDs throughout pregnancy; therefore it is important that comprehensive information on the potential risks associated with AED treatment is available. To assess the effects of prenatal exposure to AEDs on the prevalence of congenital malformations in the child. We searched the Cochrane Epilepsy Group Specialized Register (September 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (2015, Issue 11), MEDLINE (via Ovid) (1946 to September 2015), EMBASE (1974 to September 2015), Pharmline (1978 to September 2015), Reprotox (1983 to September 2015) and conference abstracts (2010-2015) without language restriction. We included prospective cohort controlled studies, cohort studies set within pregnancy registries and randomised controlled trials. Participants were women with epilepsy taking AEDs; the two control groups were women without epilepsy and women with epilepsy who were not taking AEDs during pregnancy. Three authors independently selected studies for inclusion. Five authors completed data extraction and risk of bias assessments. The primary outcome was the presence of a major congenital malformation. Secondary outcomes included specific types of major congenital malformations. Where meta-analysis was not possible, we reviewed included studies narratively. We included 50 studies, with 31 contributing to meta-analysis. Study quality varied, and given the observational design, all were at high risk of certain biases. However, biases were balanced across the AEDs investigated and we believe that the results are not explained by these biases.Children exposed to carbamazepine (CBZ) were at a higher risk of malformation than children born to women without epilepsy (N = 1367 vs 2146, risk ratio (RR) 2.01, 95% confidence interval (CI) 1.20 to 3.36) and women with

    Temporal lobe epilepsy is one of the most frequent types of human neurological diseases, and a variety of surgical procedures have been developed for the treatment of intractable cases. An alternative is the use of drug-containing reservoirs based on nanostructured materials of controlled pore sizes in order to deliver the drug without causing secondary effects. Ordered SiO 2 nanostructures were developed as drug reservoirs. The latter were prepared by the sol-gel process using tetraethyl orthosilicate TEOS as precursor to form the "sol" and P123 surfactant as the organic structure-directing agent. In addition to the nontoxic nature of amorphous silica, uniform and tunable pore sizes between 2.5 and 30 nm can be obtained in this way. The aim of this study is to investigate the potential of these materials for the storage and release of drugs in the brain. For that, we loaded valproic acid (VH) and sodic phenytoin (PH) molecules into an ordered mesoporous SiO 2 by impregnation and characterized the drug impregnated SiO 2 by standard physical and spectroscopic techniques to identify the parameters necessary to improve the capacity and quality of the reservoirs. Finally, a study of neurohistopathology of the effects of these reservoirs on brain tissue is presented.

    Polytherapy is common in the management of bipolar disorder, as are the side effects associated with this treatment strategy. The authors review the literature on drug-drug interactions involving oxcarbazepine and identify specific mechanisms that may have clinical importance. The authors provide a case report of a patient who developed phenytoin toxicity associated with an oxcarbazepine-phenytoin interaction. Co-administration of phenytoin and oxcarbazepine resulted in toxic levels of phenytoin. Therefore, the patient's daily dosage of oxcarbazepine and phenytoin were reduced. Although oxcarbazepine is an inducer of the 3A4 isoenzyme, it acts as an inhibitor of the 2C19 isoenzyme, and it can raise levels of other agents, for example, phenytoin, that are also metabolized by this isoenzyme.

    A-10-year-old girl was referred to our department for multiple hyperpigmented plaques. One week previously, she had been given one suppository of acetylsalicylic acid - phenobarbital for fever. Twelve hours after the drug intake the child developed pruritic red plaques on the left thigh. Six weeks after resolution of the acute reaction, patch tests were performed separately, with phenobarbital and acetylsalicylic acid. On 48-hour reading, only the phenobarbital patch test on residual pigmented lesion was positive. Because of possible cross-reactions between aromatic anticonvulsants, subsequent patch tests using carbamazepine and phenytoin on residual pigmented lesions were performed. They were all negative at 48-hour reading. To our knowledge, only two isolated pediatric cases of Phenobarbital-induced FDE have been reported in the literature. In this case report, as it was difficult to determine whether phenobarbital or acetylsalicylic acid was responsible for this reaction, subsequent patch tests allowed the identification of the culprit component since it was positive to phenobarbital.

    Oral cannabis extracts (OCEs) have been used in the treatment of epilepsy; however, no studies demonstrate clear efficacy. We report on a cohort of pediatric patients with epilepsy who were given OCE and followed in a single tertiary epilepsy center. A retrospective chart review of children and adolescents who were given OCE for treatment of their epilepsy was performed. Seventy-five patients were identified of which 57% reported any improvement in seizure control and 33% reported a >50% reduction in seizures (responders). If the family had moved to CO for OCE treatment, the responder rate was 47% vs. 22% for children who already were in CO. The responder rate varied based on epilepsy syndrome: Dravet 23%, Doose 0%, and Lennox-Gastaut syndrome (LGS) 88.9%. The background EEG of the 8 responders where EEG data were available was not improved. Additional benefits reported included: improved behavior/alertness (33%), improved language (10%), and improved motor skills (10%). Adverse events (AEs) occurred in 44% of patients including increased seizures (13%) and somnolence/fatigue (12%). Rare adverse events included developmental regression, abnormal movements, status epilepticus requiring intubation, and death. Our retrospective study of OCE use in pediatric patients with epilepsy demonstrates that some families reported patient improvement with treatment; however, we also found a variety of challenges and possible confounding factors in studying OCE retrospectively in an open-labeled fashion. We strongly support the need for controlled, blinded studies to evaluate the efficacy and safety of OCE for treatment of pediatric epilepsies using accurate seizure counts, formal neurocognitive assessments, as well as EEG as a biomarker. This study provides Class III evidence that OCE is well tolerated by children and adolescents with epilepsy. Copyright © 2015 Elsevier Inc. All rights reserved.

    Research was conducted to evaluate conversations about epilepsy between community-based neurologists and patients. Adverse effects of antiepileptic drugs and mood/behavioral issues were infrequently discussed, and neurologists and patients disagreed about these issues postvisit. Follow-up research was conducted to assess the impact of a previsit assessment tool on discussions of epilepsy. Twenty neurologists reviewed a tool incorporating questions from validated instruments (Adverse Events Profile [AEP] and Neurological Disorders Depression Inventory for Epilepsy [NDDI-E]). Naturally occurring interactions between neurologists and 60 patients were recorded. Neurologists and patients were interviewed separately. All components were transcribed and analyzed using sociolinguistics. Using the previsit assessment tool increased the number of discussions about adverse effects and mood/behavioral issues and increased neurologist-patient agreement about issues postvisit. Visit length did not increase significantly when the tool was used. Ten months after follow-up research, 50% of neurologists reported continuing to use the tool in everyday practice with patients with epilepsy. Copyright © 2011 Elsevier Inc. All rights reserved.

    The use of phenytoin as a prophylactic anticonvulsant after brain surgery, particularly for brain tumors, is a common practice, regardless of whether the patient has a previous history of convulsions. This treatment policy assumes that the benefits exceed the risks. Four cases are described of adverse reactions of phenytoin during the cocomitant use of cranial radiotherapy. In one patient this proved fatal. There is increasing anecdotal support in the literature for a synergistic effect between phenytoin therapy and cranial radiotherapy that can result in the life-threatening Stevens-Johnson syndrome. While the association is uncommon, four cases within 24 months in one department suggest that the routine use of postoperative phenytoin as a prophylactic anticonvulsant in the absence of a history of seizures may not be warranted, particularly if the patient is to receive cranial radiotherapy.

A retrospective analysis was performed for the clinical data of 38 children with temporal lobe epilepsy and 40 children with idiopathic epilepsy. The controls were 42 healthy children. All subjects received the following neuropsychological tests: Montreal Cognitive Assessment (MoCA) scale, verbal fluency test, digit span test, block design test, Social Anxiety Scale for Children (SASC), and Depression Self-rating Scale for Children (DSRSC). Compared with the control group, the temporal lobe epilepsy and idiopathic epilepsy groups showed significantly lower scores of MoCA, verbal fluency, digit span, and block design (Pepilepsy group, the temporal lobe epilepsy group showed significantly lower scores of MoCA, verbal fluency, digit span, and block design (Ptemporal lobe epilepsy group, MoCA score was negatively correlated with SASC score, DSRSC score, and seizure frequency (r=-0.571, -0.529, and -0.545 respectively; Pepilepsy group, MoCA score was also negatively correlated with SASC score, DSRSC score, and seizure frequency (r=-0.542, -0.487, and -0.555 respectively; Ptemporal lobe epilepsy and idiopathic epilepsy show impaired whole cognition, verbal fluency, memory, and executive function and have anxiety and depression, which are more significant in children with temporal lobe epilepsy.

    Seizures are associated with adverse outcome in infants with hypoxic-ischemic encephalopathy. We hypothesized that early administration of the anticonvulsant phenobarbital after cerebral hypoxia-ischemia could enhance the neuroprotective efficacy of delayed-onset hypothermia. We tested this hypothesis in a neonatal rodent model. Seven-day-old rats (n=104) underwent right carotid ligation, followed by 90 min 8%O2 exposure; 15 min later, they received injections of phenobarbital (40 mg/kg) or saline. One or 3h later, all were treated with hypothermia (30°C, 3h). Function and neuropathology were evaluated after 7 days (“early outcomes”) or 1 month (“late outcomes”). Early outcome assessment demonstrated better sensorimotor performance and less cortical damage in phenobarbital-treated groups; there were no differences between groups in which the hypothermia delay was shortened from 3h to 1h. Late outcome assessment confirmed sustained benefits of phenobarbital+hypothermia treatment; sensorimotor performance was better (persistent attenuation of contralateral forepaw placing deficits and absence of contralateral forepaw neglect); neuropathology scores were lower (medians, phenobarbital 2, saline 8.5, pphenobarbital may augment the neuroprotective efficacy of therapeutic hypothermia.

    Neonatal status epilepticus (SE) is often associated with adverse cognitive and epilepsy outcomes. We investigate the effects of three episodes of kainic acid-induced SE (3KA-SE) and maternal separation in immature rats on subsequent learning, seizure susceptibility, and consequences, and the anticonvulsant effects of phenobarbital, according to sex, type, and age at early life (EL) event. 3KA-SE or maternal separation was induced on postnatal days (PN) 4-6 or 14-16. Rats were tested on Barnes maze (PN16-19), or lithium-pilocarpine SE (PN19) or flurothyl seizures (PN32). The anticonvulsant effects of phenobarbital (20 or 40 mg/kg/rat, intraperitoneally) pretreatment were tested on flurothyl seizures. FluoroJadeB staining assessed hippocampal injury. 3KA-SE or separation on PN4-6 caused more transient learning delays in males and did not alter lithium-pilocarpine SE latencies, but aggravated its outcomes in females. Anticonvulsant effects of phenobarbital were preserved and potentiated in specific groups depending on sex, type, and age at EL event. Early life 3KA-SE and maternal separation cause more but transient cognitive deficits in males but aggravate the consequences of subsequent lithium-pilocarpine SE in females. In contrast, on flurothyl seizures, EL events showed either beneficial or no effect, depending on gender, type, and age at EL events. © 2014 John Wiley & Sons Ltd.

  9. An acidosis-sparing ketogenic (ASK) diet to improve efficacy and reduce adverse effects in the treatment of refractory epilepsy.

    Diets that increase production of ketone bodies to provide alternative fuel for the brain are evolving from the classic ketogenic diet for epilepsy devised nearly a century ago. The classic ketogenic diet and its more recent variants all appear to have similar efficacy with approximately 50% of users showing a greater than 50% seizure reduction. They all require significant medical and dietetic support, and there are tolerability issues. A review suggests that low-grade chronic metabolic acidosis associated with ketosis is likely to be an important contributor to the short term and long term adverse effects of ketogenic diets. Recent studies, particularly with the characterization of the acid sensing ion channels, suggest that chronic metabolic acidosis may increase the propensity for seizures. It is also known that low-grade chronic metabolic acidosis has a broad range of negative health effects and an increased risk of early mortality in the general population. The modified ketogenic dietary treatment we propose is formulated to limit acidosis by measures that include monitoring protein intake and maximizing consumption of alkaline mineral-rich, low carbohydrate green vegetables. We hypothesize that this acidosis-sparing ketogenic diet is expected to be associated with less adverse effects and improved efficacy. A case history of life-long intractable epilepsy shows this diet to be a successful long-term strategy but, clearly, clinical studies are needed. Copyright © 2017 Elsevier Inc. All rights reserved.

    Phenobarbital is the most commonly utilized drug for neonatal seizures. However, questions regarding safety and efficacy of this drug make it particularly compelling to identify adjunct therapies that could boost therapeutic benefit. One potential adjunct therapy is melatonin. Melatonin is used clinically in neonatal and pediatric populations, and moreover, it exerts anticonvulsant actions in adult rats. However, it has not been previously evaluated for anticonvulsant effects in neonatal rats. Here, we tested the hypothesis that melatonin would exert anticonvulsant effects, either alone, or in combination with phenobarbital. Postnatal day (P)7 rats were treated with phenobarbital (0-40mg/kg) and/or melatonin (0-80mg/kg) prior to chemoconvulsant challenge with pentylenetetrazole (100mg/kg). We found that melatonin significantly potentiated the anticonvulsant efficacy of phenobarbital, but did not exert anticonvulsant effects on its own. These data provide additional evidence for the further examination of melatonin as an adjunct therapy in neonatal/pediatric epilepsy. Copyright © 2013 Elsevier B.V. All rights reserved.

    To examine the association between autism spectrum disorder (ASD) and epilepsy in children. A total of 190 children with ASD were enrolled. A self-designed questionnaire, Childhood Autism Rating Scale, and Autism Behavior Checklist were used to determine the association between ASD and epilepsy. Among the 190 children with ASD, 20 (10.5%) had epileptic seizures and 12 (6.3%) were diagnosed with epilepsy. The rates of abnormal physical development and hearing disorders before the age of one year were significantly higher in ASD children with epileptic seizures than in those without epileptic seizures (Pchildren diagnosed with epilepsy and those receiving epilepsy treatment had a significantly increased rate of abnormal physical development before the age of one year (Pchildren with epileptic seizures had poorer sensory responses and behavioral competencies than those without epileptic seizures (PEpilepsy treatment have a positive effect on behavioral competencies in ASD children (Pepilepsy in children. The possibility of the comorbidity between ASD and epilepsy may be assessed according to the status of growth and development before the age of one year, sensory responses and behavioral competencies, and the presence or absence of epileptic seizures.

  13. The treatment of autism with low-dose phenytoin: a case report.

    The drug treatment of autism spectrum disorders is often poorly tolerated and has traditionally targeted associated conditions (such as inattention or irritability) that frequently coexist, with limited benefit for the core social deficits. Here, I describe the novel use of a low dose of the anti-epileptic phenytoin to enhance social functioning in a patient with an autism spectrum disorder. I present the case of a 19-year-old Caucasian man with autism spectrum disorder treated with stimulant medication since early childhood. He experienced long-standing difficulties in establishing and maintaining relationships and reading social cues, and was socially isolated. Within 10 minutes of a single sublingual low dose of phenytoin there was an immediate observable improvement in his eye contact and integration of both verbal and non-verbal communication. This enhanced social functioning associated with his adherence to the low-dose phenytoin therapy was maintained for over 18 months of follow-up. These clinical observations were supported by ratings using the Autism-Spectrum Quotient and the Depression, Anxiety and Stress Scales, recorded pre-treatment and after seven months on 5mg phenytoin. This case report provides the first potential evidence that a low dose of phenytoin, a widely used and well tolerated anti-epileptic medication, may be capable of modifying the core social cognitive deficits associated with autism spectrum disorders. While acknowledging this is a single case study, the lack of availability of safe and effective treatments to address the important core deficits associated with autism spectrum disorders makes this case noteworthy.

    Meningiomas are common intracranial tumors, and despite surgery or therapy with anti-epileptic drugs (AEDs), many patients suffer from seizures. Epilepsy has a significant impact on quality of life (QoL) in non-tumor populations, but the impact of epilepsy on QoL in patients with meningioma is unknown. Our aim was to evaluate the impact of epilepsy on QoL in patients that have undergone resection of a benign meningioma. We recruited meningioma patients without epilepsy (n=109), meningioma patients with epilepsy (n=56), and epilepsy patients without meningioma (n=64). QoL was measured with the Short Form 36 version 2 (SF-36), the Functional Assessment of Cancer Therapy (FACT-BR), and the Liverpool Adverse Events Profile (LAEP). Regression analyses identified significant determinants of QoL. Patients with meningioma and epilepsy had poorer QoL scores than meningioma patients without epilepsy in all measures. In FACT-BR, this difference was significant. Multiple regression analyses demonstrated that current AED use had a greater impact on QoL scores than recent seizures. Other variables associated with impaired QoL included depression, unemployment, and meningioma attributed symptoms. Epilepsy has a negative impact on quality of life in patients with benign meningioma. AED use is correlated with impaired QoL and raised LAEP scores, suggesting that AEDs and adverse effects may have led to impaired QoL in our meningioma patients with epilepsy. The severity of epilepsy in our meningioma population was comparatively mild; therefore, a more conservative approach to AED therapy may be indicated in an attempt to minimize adverse effects. © 2016 John Wiley & Sons A/S.

    Migrating partial seizures in infancy (MPSI) are an age-specific epilepsy syndrome characterized by migrating focal seizures, which are intractable to various antiepileptic drugs and cause severe developmental delay. We report a case of MPSI with heterozygous missense mutation in KCNT1, which was successfully managed by ketogenic diet. At age 2months, the patient developed epilepsy initially manifesting focal seizures with eye deviation and apnea, then evolving to secondarily generalized clonic convulsion. Various antiepileptic drugs including phenytoin, valproic acid, zonisamide, clobazam, levetiracetam, vitamin B6, and carbamazepine were not effective, but high-dose phenobarbital allowed discontinuation of midazolam infusion. Ictal scalp electroencephalogram showed migrating focal seizures. MPSI was suspected and she was transferred to our hospital for further treatment. Potassium bromide (KBr) was partially effective, but the effect was transient. High-dose KBr caused severe adverse effects such as over-sedation and hypercapnia, with no further effects on the seizures. At age 9months, we started a ketogenic diet, which improved seizure frequency and severity without obvious adverse effects, allowing her to be discharged from hospital. Ketogenic diet should be tried in patients with MPSI unresponsive to antiepileptic drugs. In MPSI, the difference in treatment response in patients with and those without KCNT1 mutation remains unknown. Accumulation of case reports would contribute to establish effective treatment options for MPSI. Copyright © 2016 The Japanese Society of Child Neurology. Published by Elsevier B.V.

    Convulsive status epilepticus can exert profound cardiovascular effects in adults including ventricular depolarization-repolarization abnormalities. Whether status epilepticus adversely affects ventricular electrical properties in children is less understood. Therefore, we sought to characterize ventricular alterations and the associated clinical factors in children following convulsive status epilepticus. We conducted a 2-year retrospective, case-control study. Children between 1 month and 21 years of age were included if they were admitted to the pediatric intensive care unit with primary diagnosis of convulsive status epilepticus and had 12-lead electrocardiogram (ECG) within 24 hours of admission. Children with heart disease, ion channelopathy, or on vasoactive medications were excluded. Age-matched control subjects had no history of seizures or epilepsy. The primary outcome was ventricular abnormalities represented by ST segment changes, abnormal T wave, QRS axis deviation, and corrected QT (QTc) interval prolongation. The secondary outcomes included QT/RR relationship, beat-to-beat QTc interval variability, ECG interval measurement between groups, and clinical factors associated with ECG abnormalities. Of 317 eligible children, 59 met the inclusion criteria. History of epilepsy was present in 31 children (epileptic) and absent in 28 children (non-epileptic). Compared with the control subjects (n = 31), the status epilepticus groups were more likely to have an abnormal ECG with overall odds ratio of 3.8 and 7.0 for the non-epileptic and the epileptic groups respectively. Simple linear regression analysis demonstrated that children with epilepsy exhibited impaired dependence and adaptation of the QT interval on heart rate. Beat-to-beat QTc interval variability, a marker of ventricular repolarization instability, was increased in children with epilepsy. Convulsive status epilepticus can adversely affect ventricular electrical properties and stability in children

Se necesitan más estudios para poder contestar estas preguntas.In this paper we review the current information regarding the use of new antiepileptic drugs (AEDs used as monotherapy in children. We specifically include the following AEDs: lamotrigine (Lamictal®, topiramate (Topamax®, zonisamide (Zonegran®, levetiracetam (Keppra®, and oxcarbazepine (Trileptal®. All of these AEDs have a broad spectrum of action in the treatment of partial and generalized seizures, except Oxcarbazepine, which is effective only in partial seizures. It is unclear whether or not monotherapy with the new AEDs offers higher efficacy and/or lower side effects compared to classic AEDs (phenobarbital, phenytoin, carbamazepine, or valproate thereby significantly improving the quality of life in children with epilepsy. More studies are needed to answer these questions.

    Long-term ketogenic diet (KD) treatment has been shown to induce liver steatosis and gallstone formation in some in vivo and clinical studies. The aim of this retrospective study was to evaluate the hepatic side effects of KD in epileptic children. A total of 141 patients (mean age: 7.1±4.1years [2-18 years], 45.4% girls), receiving KD at least one year for intractable epilepsy due to different diagnoses (congenital brain defects, GLUT-1 deficiency, West syndrome, tuberous sclerosis, hypoxic brain injury, etc.) were included in the study. Serum triglyceride, cholesterol, aminotransferase, bilirubin, protein and albumin levels and abdominal ultrasonography were recorded before and at 1, 3, 6, and 12 months following after diet initiation. The mean duration of KD was 15.9±4.3months. At one month of therapy, three patients had elevated alanine and aspartate aminotransferase levels. These patients were receiving ketogenic diet for Doose syndrome, idiopathic epilepsy and GLUT-1 deficiency. Hepatosteatosis was detected in three patients at 6 months of treatment. Two of these patients were treated with KD for the primary diagnosis of tuberous sclerosis and one for Landau Kleffner syndrome. Cholelithiasis was detected in two patients at 12 months of treatment. They were receiving treatment for West syndrome and hypoxic brain injury sequelae. Long-term ketogenic diet treatment stimulates liver parenchymal injury, hepatic steatosis and gallstone formation. Patients should be monitored by screening liver enzymes and abdominal ultrasonography in order to detect these side effects. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd.

    The Extracorporeal Treatments in Poisoning (EXTRIP) Workgroup conducted a systematic literature review using a standardized process to develop evidence-based recommendations on the use of extracorporeal treatment (ECTR) in patients with phenytoin poisoning. The authors reviewed all articles, extracted data, summarized findings, and proposed structured voting statements following a predetermined format. A 2-round modified Delphi method was used to reach a consensus on voting statements, and the RAND/UCLA Appropriateness Method was used to quantify disagreement. 51 articles met the inclusion criteria. Only case reports, case series, and pharmacokinetic studies were identified, yielding a very low quality of evidence. Clinical data from 31 patients and toxicokinetic grading from 46 patients were abstracted. The workgroup concluded that phenytoin is moderately dialyzable (level of evidence = C) despite its high protein binding and made the following recommendations. ECTR would be reasonable in select cases of severe phenytoin poisoning (neutral recommendation, 3D). ECTR is suggested if prolonged coma is present or expected (graded 2D) and it would be reasonable if prolonged incapacitating ataxia is present or expected (graded 3D). If ECTR is used, it should be discontinued when clinical improvement is apparent (graded 1D). The preferred ECTR modality in phenytoin poisoning is intermittent hemodialysis (graded 1D), but hemoperfusion is an acceptable alternative if hemodialysis is not available (graded 1D). In summary, phenytoin appears to be amenable to extracorporeal removal. However, because of the low incidence of irreversible tissue injury or death related to phenytoin poisoning and the relatively limited effect of ECTR on phenytoin removal, the workgroup proposed the use of ECTR only in very select patients with severe phenytoin poisoning.

    The effects of phenobarbital on taste aversion induced by x-radiation were examined. Rats were adapted to a 23 hr 50 min water deprivation schedule. On the Treatment Day animals were given a novel 0.125% Na saccharin solution during the 10 min drinking session and were then exposed to 100 rads of x-radiation. The saccharin solution was presented again on six subsequent Test Days. Phenobarbital in doses of 20, 40, 60 and 80 mg/kg was adminstered 15 min prior to drinking on the first Test Day. Results demonstrate the phenobarbital in all doses tested has a significant attenuating effect on radiation induced taste aversion

    Seizures are present in over 90% of infants and children with Wolf-Hirschhorn syndrome (WHS). When present, they significantly affect quality of life. The goal of this study was to use caregiver reports to describe the comparative efficacies of commonly used antiepileptic medications in a large population of individuals with WHS. A web-based, confidential caregiver survey was developed to capture seizure semiology and a chronologic record of seizure treatments as well as responses to each treatment. Adverse events for each drug were also cataloged. We received 141 complete survey responses (47% response rate) describing the seizures of individuals ranging in age from 4months to 61years (90 females: 51 males). Using the Early Childhood Epilepsy Severity Scale (E-Chess), WHS-associated seizures are demonstrably severe regardless of deletion size. The best-performing antiepileptic drugs (AEDs) for controlling seizures in this cohort were broad spectrum drugs clobazam, levetiracetam, and lamotrigine; whereas, the three commonly used carboxamide class drugs: carbamazepine, phenytoin, and oxcarbazepine, were reported to have little effect on, or even exacerbate, seizures. The carboxamide class drugs, along with phenobarbital and topiramate, were also associated with the highest rate of intolerance due to cooccurrence of adverse events. Levetiracetam, clobazam, and clonazepam demonstrated higher tolerability and comparatively less severe adverse events (Wilcoxon rank sum comparison between performance of levetiracetam and carboxamide class drugs gives a psyndromes which may have complex seizure etiologies.

    Phenobarbital (Luminal), well known as a hypnotic agent, plays also an important role in the medical treatment of epilepsy. With the object of studying the metabolism of this medicament in the living system, the synthesis of phenobarbital marked in position 2 of the pyrimidinic ring has been effected. It has been necessary, in order to carry out to research into the metabolism of this product, to have a phenobarbital marked in position 5 of the pyrimidinic ring. This synthesis, making it possible to introduce C-14 into position 5 of the pyrimidinic ring, consists of seven stages starting from C-14 carboxyl benzoic acid having a specific activity of 25 mc/mM. The melting point of the final product is 172 - 173 deg. C and its specific activity is 11.15 mc/mM. The overall radioactive yield of the pure product, with respect to the original benzoic acid (10 mM) is of the order of 3 per cent. The purity of the product has been controlled by paper chromatography; it is of the order of 99 per cent.

    The possible influence of sucralfate on phenytoin absorption was investigated in a double-blind, placebo controlled study. Concomitant administration of 1 g sucralfate reduced the absorption of 300 mg phenytoin capsules by 20% as measured by the area under the curve from 0-48 h. This could be of significance in epileptic patients stabilised on phenytoin in whom sucralfate is used in ulcer treatment. PMID:3840029

    Over a period of nine months twenty-five epileptic patients were treated with the oral loading dose of phenytoin. The dose ranged from 12 to 23 mg/kg body weight during 1 to 12 hours. In 20 patients with serial seizures or intolerance to other antiepileptic drugs this treatment was effective. Seizures also stopped in 2 of 4 patients with serial partial motor seizures. These 2 patients required both higher loading dose and faster rate of administration than the other patients. A patient with epilepsia partialis continua failed to respond to the treatment. Patients that received phenytoin through the naso-gastric tube, in respect to oral administration, required higher doses to obtain therapeutic plasma levels of phenytoin. One patient had mild nausea, 3 mild dizziness, and 1 tinitus on the first day of the treatment. There was no correlation between a given dose and the achieved phenytoin plasma levels. In our opinion the therapy with oral loading dose of phenytoin is highly effective in the treatment of serial generalized seizures and rapid antiepileptic drug substitution, and partially effective in the prevention of partial motor seizures. It produces only mild and transient side-effects.

  7. Treatment of Acute Tacrolimus Toxicity with Phenytoin in Solid Organ Transplant Recipients

    Full Text Available The pharmacokinetics of tacrolimus are influenced by many factors, including genetic variability, acute infections, liver dysfunction, and interacting medications, which can result in elevated concentrations. The most appropriate management of acute tacrolimus toxicity has not been defined though case reports exist describing the therapeutic use of enzyme inducers to increase tacrolimus metabolism and decrease concentrations. We are reporting on the utilization of phenytoin to assist in decreasing tacrolimus concentrations in a case series of four solid organ transplant recipients with acute, symptomatic tacrolimus toxicity presenting with elevated serum creatinine, potassium, and tacrolimus trough concentrations greater than 30 ng/mL. All four patients had the potential causative agents stopped or temporarily held and were given 300 to 400 mg/day of phenytoin for two to three days. Within three days of beginning phenytoin, all four patients had a decrease in tacrolimus concentration to less than 15 ng/mL, a return to or near baseline creatinine concentration, and lack of phenytoin-related side effects. Therefore, phenytoin appears to be a safe and potentially beneficial treatment option in patients with symptomatic tacrolimus toxicity.

    Rats were exposed to toluene at a wide range of concentrations from 50 to 4000 ppm for six hours, and the effects of ethanol and phenobarbital (PB) treatments on the pharmacokinetics of toluene metabolism were investigated. Ethanol treatment influenced toluene metabolism mainly at low exposure concentrations. Thus ethanol accelerated the clearance of toluene from blood only when the blood concentration of toluene was not high (less than 360 microM), and ethanol increased hippuric acid (HA) ex...

    Pharmacogenetic studies have shown that genetic defects in drug-metabolizing enzymes encoded by CYP2C9, CYP2C19 genes and by the transporter ABCB1 gene can influence phenytoin (PTH) plasma levels and toxicity. The patient reported here is a 2-year-old girl with a medical history of cryptogenic (probably symptomatic) epilepsy, who had her first focal seizure with secondary generalization at 13 months of age. She initially received oral valproate treatment and three months later, she was prescribed an oral oxcarbazepine treatment. At 20 months of age, she was admitted to the Emergency Department because of generalized convulsive Status Epilepticus needing to be immediately treated with rectal diazepam (0.5 mg kg(-1)), intravenous diazepam (0.3 mg kg(-1)), and intravenous phenytoin with an initial-loading dose of 15 mg kg(-1). However, two hours after the initial-loading dose of PTH, the patient developed dizziness, nystagmus, ataxia and excessive sedation. Other potential causes of PTH toxicity were excluded such as drug interactions, decreased albumin or lab error. Therefore, to explain the neurological toxicity, PTH plasma levels and CYP2C9, CYP2C19 and ABCB1 genetic polymorphisms were analyzed. Initial plasma PTH levels were higher than expected (69 mg l(-1); normal range: 10-20 mg l(-1)), and the patient was homozygous for the CYP2C9*2 allele, heterozygous for the CYP2C19*4 allele and homozygous for the 3435C and 1236C ABCB1 alleles. Present findings support the previously established relationship between CYP2C9 and CYP2C19 genetic polymorphisms and the increased risk to develop PTH toxicity owing to high plasma concentrations. Nevertheless, although the association of these genes with PTH-induced adverse effects has been well-documented in adult populations, this is the first report examining the influence of these genetic polymorphisms on PTH plasma levels and toxicity in a pediatric patient.

Phenytoin, as the prototype for all anticonvulsants, was already positioned as an analgesic compound 70 years ago. Since these initial findings, the data that have been gathered have supported the use of anticonvulsants as painkillers – from phenytoin up to and including more recent anticonvulsants such as gabapentin and pregabalin. Since 1942, a number of papers supported phenytoin’s therapeutic effects in trigeminal neuralgia (Table 1. The introduction of carbamazepine in 1962 by Geigy shifted the interest of neurologists from phenytoin as a treatment for trigeminal neuralgia to carbamazepine, without sound scientific evidence. To date, no convincing randomized controlled trials (RCTs have been published supporting the role of carbamazepine in trigeminal neuralgia, and we could not identify a single study comparing the effects of phenytoin with those of carbamazepine. Accordingly, phenytoin should probably be considered more often as a viable therapy for (treatmentresistant trigeminal neuralgia.

    To develop and implement interventions to improve the quality of life (QOL) in children with epilepsy, it is important for clinicians and researchers to understand the effects of the children's parents' perception of stigma. The purpose of this study was to identify a relationship between patient clinical characteristics and perception of stigma in the parents of children with epilepsy. Parents of children with epilepsy were recruited from our university hospital between April 1, 2005 and March 31, 2012. Items for the Parent Stigma Scale were developed from the literature and open-ended interviews with parents of children with epilepsy about their concerns and fears, including those related to stigma. Parents were asked to respond to five items, each on a 5-point scale from 1 (strongly disagree) to 5 (strongly agree). Assessments were performed for each clinical characteristic, such as child's sex, age at seizure onset, family history of epilepsy, seizure frequency, presence of status epilepticus (SE), presence of treatment-related adverse events, and the scores of each scale. A total of 52 parents of children with epilepsy and 10 parents of healthy children were enrolled in the study. Parents of children with epilepsy showed significantly higher scores on the questionnaire than parents of healthy children. In multiple regression analysis, greater perceptions of stigma were associated with a seizure frequency of more than one per month (p=0.0036, B=1.104, β=0.402). In contrast, the presence of prior febrile seizures (p=0.0034, B=-1.297, β=-0.308) and family history of epilepsy (p=0.0066, B=-1.613, β=-0.277) were associated with lower perceptions of stigma. Greater parental perceptions of stigma were seen with the presence of monthly seizures. Parents of children with epilepsy are at risk of significant perceptions of stigma. Seizure severity, indicated by the presence of monthly seizures, was associated with greater perceptions of stigma in parents. In addition

    Phenytoin (PHT), an anticonvulsant agent, widely used for the treatment of epilepsy has been reported to exhibit toxic side effects. The present study investigated the protective effects of kolaviron and vitamin E on hematotoxicity and neurotoxicity induced by phenytoin, in prepubertal male rats. The animals were treated with PHT (75 mg/kg) separately or in combination with either kolaviron (200 mg/kg) or vitamin E (500 mg/kg) for 14 days. Phenytoin treatment significantly decreased the hemoglobin, white blood cells, lymphocytes and mean corpuscular volume levels without affecting red blood cell, packed cell volume, neutrophils, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration when compared with the control rats. There was a significant increase in lipid peroxidation and hydrogen peroxide levels with marked depletion in antioxidant status in brains of PHT-treated rats when compared with the control. Although PHT treatment had no effect on the granular layer, widest diameter of Purkinje cells and Purkinje layer of the cerebellum, it significantly reduced its molecular layer and the density of Purkinje cell. Administration of PHT significantly reduced the densities of the granule cells of the dentate gyrus and the pyramidal neurons of the cornu ammonis of hippocampus proper. Co-treatment with kolaviron and vitamin E effectively reversed the PHT-mediated alterations in the hematology, brain antioxidant status and histomorphometry when compared to PHT only. Taken together, the present data indicate the abilities of kolaviron and vitamin E to ameliorate phenytoin-induced hematotoxicity and oxidative stress in brains of rats.

  14. The bumetanide prodrug BUM5, but not bumetanide, potentiates the antiseizure effect of phenobarbital in adult epileptic mice.

    The loop diuretic bumetanide has been reported to potentiate the antiseizure activity of phenobarbital in rodent models of neonatal seizures, most likely as a result of inhibition of the chloride importer Na-K-Cl cotransporter isoform 1 (NKCC1) in the brain. In view of the intractability of neonatal seizures, the preclinical findings prompted a clinical trial in neonates on bumetanide as an add-on to phenobarbital, which, however, had to be terminated because of ototoxicity and lack of efficacy. We have recently shown that bumetanide penetrates only poorly into the brain, so that we developed lipophilic prodrugs such as BUM5, the N,N-dimethylaminoethylester of bumetanide, which penetrate more easily into the brain and are converted to bumetanide. In the present study, we used a new strategy to test whether BUM5 is more potent than bumetanide in potentiating the antiseizure effect of phenobarbital. Adult mice were made epileptic by pilocarpine, and the antiseizure effects of bumetanide, BUM5, and phenobarbital alone or in combination were determined by the maximal electroshock seizure threshold test. In nonepileptic mice, only phenobarbital exerted seizure threshold-increasing activity, and this was not potentiated by the NKCC1 inhibitors. In contrast, a marked potentiation of phenobarbital by BUM5, but not bumetanide, was determined in epileptic mice. Thus, bumetanide is not capable of potentiating phenobarbital's antiseizure effect in an adult mouse model, which, however, can be overcome by using the prodrug BUM5. These data substantiate that BUM5 is a promising tool compound for target validation and proof-of-concept studies on the role of NKCC1 in brain diseases.

    Learning Disorders (LD) are defined as disorders that interfere with academic performance or with daily activities that require reading, writing or mathematical skills in subjects with a normal intelligence quotient (IQ). The prevalence of LD in the general population has been found to be 2-10%, and reading disorders are the most frequent subtype. Epilepsy is one of the most common serious neurological disorders in childhood. LD are more common in children with epilepsy than in the general population. As a consequence, the risk of cognitive impairment in children with epilepsy is high, and a review of the literature needs to be fully presented. Narrative review including articles regarding LD in children with various epileptic syndromes published in the international medical literature. LD are more frequent among children with epilepsy. The etiology is multifactorial, being affected by the type of epileptic syndrome, the age of onset and the antiepileptic treatment being selected. LD can be either permanent or state-dependent. Each category has different treatment protocols and prognosis. Despite the fact that the findings of the studies discussed in our article support the evidence that epilepsy in childhood impairs the cognitive function, we should not underestimate the role of demographic and psychosocial factors on academic performance of children with epilepsy. Despite the high prevalence of LD, a healthy family and school environment can help reduce its impact on the patient's quality of life. © Springer-Verlag 2010

    Phenytoin, an anticonvulsant agent used for the treatment of epilepsy has been reported to exhibit toxic side effects on the liver and testes. The present study investigated the protective effects of kolaviron (KV, a bioflavonoid from Garcinia kola seeds) against hepatic and testicular damage in rats exposed to phenytoin. The study consisted of four groups of six rats per group. Group I rats received 2 mL/kg of corn alone while group II received 75 mg/kg of phenytoin (PHT) alone. Groups III and IV were co-treated with kolaviron (200 mg/kg KV) and vitamin E (500 mg/kg VTE), respectively, for 14 days. The antioxidant status, hepatic and reproductive functional parameters were subsequently determined. PHT treatment significantly (p < 0.05) increased superoxide dismutase (SOD) and catalase (CAT) activities, elevated lipid peroxidation (LPO) and hydrogen peroxide (H2O2) levels along with significant reduction in the hepatic and testicular levels of glutathione (GSH). Moreover, PHT exposure elicited significant increases in alkaline phosphatase (ALP) and aspartate aminotransferase (AST) levels. The significant reduction in seminal epithelium thickness and the diameter of seminiferous tubules was accompanied with marked decrease in sperm motility, sperm count, and viability in PHT-treated rats. However, antioxidant status and the functional indices of liver and testes were restored to near control levels in rats co-treated with KV and VTE. In conclusion, KV and VTE protect the liver and testes against functional impairment due to PHT treatment.

The cough was not accompanied by any other symptom or sign as his physical exam was completely normal. Further investigation with chest CT and spirometry was unremarkable. This symptom persisted for six months and did not resolve until we weaned him off of phenytoin. According to the Naranjo Adverse Drug Reaction Probability Scale, his cough was classified as being probably (score +6 related to the use of this antiepileptic drug. To our knowledge, there has been only one study that reported phenytoin-triggered cough. It described a postoperative patient who developed cough and bronchospasm after receiving IV phenytoin. By reporting our case and discussing the literature on this specific topic, we have essentially two goals. First, we intend to remind clinicians that isolated persistent cough can be an adverse reaction to phenytoin. Second, we hope to encourage further studies that will be able to elucidate the association presented herein.

    Abstract Phenobarbital is an old antiepileptic drug used in severe epilepsy. Despite this, little is written about the need for dose adjustments in renal replacement therapy. Most sources recommend a moderately increased dose guided by therapeutic drug monitoring. A 14 year old boy with nonketotic hyperglycinemia, a rare inborn error of metabolism, characterized by high levels of glycine, epilepsy, spasticity, and cognitive impairment, was admitted to the emergency department with respiratory failure after a few days of fever and cough. The boy was unconscious at admittance and had acute renal and hepatic failure. Due to the acute respiratory infection, hypoxic hepatic and renal failure occurred and the patient had a status epilepticus. The patient was intubated and mechanically ventilated. Continuous renal replacement therapy was initiated. Despite increased phenobarbital doses, therapeutic levels were not reached until the dose was increased to 500 mg twice daily. Therapeutic drug monitoring was performed in plasma and dialysate. Calculations revealed that phenobarbital was almost freely dialyzed. Correct dosing of drugs in patients on renal replacement therapy may need a multidisciplinary approach and guidance by therapeutic drug monitoring. PMID:25101986

    Little is known about whether Asian children with epilepsy have more attention-deficit hyperactivity disorder (ADHD)-related symptoms, emotional/ behavioral problems, and physical conditions compared with those described in Western studies. The authors investigated the rates of ADHD-related symptoms, emotional/behavioral problems, and physical conditions among pediatric patients with epilepsy. We recruited 61 patients with epilepsy, aged 6-16 years, and 122 age-, sex-, and parental education-matched school controls. Data on demographics, parental reports on the Child Behavior Checklist (CBCL) and Swanson, Nolan, and Pelham, version IV scale (SNAP-IV), and medical records were collected. The average full-scale intelligence quotient of the case group was 95.8. There were 11 (18.0%), 7 (11.5%), 26 (42.6%), and 26 (42.6%) of children with epilepsy ever clinically diagnosed with developmental delay, overt ADHD symptoms, allergies reported by physicians, and behavior problems measured by the CBCL, respectively. Those children with epilepsy had more severe ADHD-related symptoms and a wider range of emotional/behavioral problems than controls (Cohen's d 0.36-0.80). The rate of potential cases of ADHD among children with epilepsy was 24.6%. A history of developmental delay predicted ADHD- related symptoms and internalizing and externalizing problems. Among children with epilepsy, a longer duration of treatment with antiepileptic drugs predicted externalizing problems, and an earlier onset of epilepsy predicted inattention and hyperactivity/impulsivity. Our findings imply that clinicians should assess physical and emotional/behavioral problems among children with epilepsy in order to provide interventions to offset possible adverse psychiatric outcomes.

    Full Text Available Status epilepticus (SE is a life-threatening neurological emergency that requires prompt diagnosis and treatment. SE may be classified into convulsive and non-convulsive types, based on the presence of rhythmic jerking of the extremities. Clinically, tonic-clonic convulsive SE (CSE is divided into four subsequent stages: Early, established, refractory and super-refractory. Initial elements of resuscitation include airway protection, haemodynamic resuscitation and seizure control. Further treatment should then be guided by the diagnostic workup. Rapid treatment of early SE is achieved with intravenous (IV lorazepam or intramuscular midazolam. In established SE, IV antiepileptic drugs (AEDs (phenytoin/fosphenytoin, valproate, levetiracetam, phenobarbital are most commonly used, but there is no Class I evidence for choosing one over the other. Considered overall, cumulative data from the literature are consistent with valproate and levetiracetam, being a safe and effective therapeutic alternative to phenobarbital and phenytoin for treatment of established SE. Refractory SE (RSE and super-RSE are treated with anaesthetic medications (propofol, midazolam, thiopental/pentobarbital, ketamine, non-anaesthetic drugs (lidocaine, magnesium, pyridoxine, AEDs (levetiracetam, lacosamide, topiramate, lacosamide, pregabalin, gabapentin and other cause-directed treatments with low success rates. Potential non-pharmacologic interventions to be considered in super-RSE include hypothermia, electroconvulsive therapy, ketogenic diet, immunomodulatory treatments, emergency resective epilepsy surgery, cerebrospinal fluid drainage and vagal nerve or deep brain stimulation or transcranial magnetic stimulation. Diagnosis of non-CSE requires continuous electroencephalography and involves a high index of suspicion in all patients with an altered mental status of unclear cause or with a prolonged postictal state. Treatment options include addressing underlying causes and

    Death in children with epilepsy is profoundly disturbing, with lasting effects on the family, community, and health care providers. The overall risk of death for children with epilepsy is about ten times that of the general population. However, the risk of premature death for children without associated neurological comorbidities is similar to that of the general population, and most deaths are related to the cause of the epilepsy or associated neurological disability, not seizures. The most common cause of seizure-related death in children with epilepsy is sudden unexpected death in epilepsy (SUDEP). SUDEP is relatively uncommon in childhood, but the risk increases if epilepsy persists into adulthood. Although the direct cause of SUDEP remains unknown, most often death follows a generalized convulsive seizure and the risk of SUDEP is strongly related to drug-resistant epilepsy and frequent generalized tonic-clonic seizures. The most effective SUDEP prevention strategy is to reduce the frequency of seizures, although a number of seizure detection devices are under development and in the future may prove to be useful for seizure detection for those at particularly high risk. There are distinct benefits for health care professionals to discuss mortality with the family soon after the diagnosis of epilepsy. An individual approach is appropriate. When a child with epilepsy dies, particularly if the death was unexpected, family grief may be profound. Physicians and other health care professionals have a critical role in supporting families that lose a child to epilepsy. This review will provide health care providers with information needed to discuss the risk of death in children with epilepsy and support families following a loss. Copyright © 2017 Elsevier Inc.

    Low-frequency stimulation (LFS) is a potential therapy utilized in patients who do not achieve satisfactory control of seizures with pharmacological treatments. Here, we investigated the interaction between anticonvulsant effects of LFS and phenobarbital (a commonly used medicine) on amygdala-kindled seizures in rats. Animals were kindled by electrical stimulation of basolateral amygdala in a rapid manner (12 stimulations/day). Fully kindled animals randomly received one of the three treatment choices: phenobarbital (1, 2, 3, 4 and 8 mg/kg; i.p.; 30 min before kindling stimulation), LFS (one or 4 packages contained 100 or 200 monophasic square wave pulses, 0.1-ms pulse duration at 1 Hz, immediately before kindling stimulation) or a combination of both (phenobarbital at 3 mg/kg and LFS). Phenobarbital alone at the doses of 1, 2 and 3 mg/kg had no significant effect on the main seizure parameters. LFS application always produced anticonvulsant effects unless applied with the pattern of one package of 100 pulses, which is considered as non-effective. All the seizure parameters were significantly reduced when phenobarbital (3 mg/kg) was administered prior to the application of the non-effective pattern of LFS. Phenobarbital (3 mg/kg) also increased the anticonvulsant actions of the effective LFS pattern. Our results provide an evidence of a positive cumulative anticonvulsant effect of LFS and phenobarbital, suggesting a potential combination therapy at sub-threshold dosages of phenobarbital and LFS to achieve a satisfactory clinical effect.

  8. Health habits, attitudes and behavior towards oral health of children with epilepsy

    2007-01-01

    Full Text Available Introduction: Children suffering from epilepsy are high at risk of oral diseases primarily due to their underlying medical condition which can have an impact on the maintenance level of oral hygiene, but also due to adverse effects of antiepileptic drugs. Objective. The aim of this paper was to identify habits, attitudes and behavior of children with epilepsy and parents in respect to oral health. Method. The experimental group consisted of 50 children with epilepsy, 24 boys and 26 girls, 7-14 years old, mean age 11.2±2.2 years. The control group consisted of healthy children, matched by age and gender. The instruments of investigation consisted of the structured interview of children and parents concerning oral health habits, attitudes and behavior. We used medical records of children with epilepsy as a source of information on their diagnosis, duration of the illness and current therapy. Statistical analysis was performed by chi-squared test, nonparametric correlation, Wilcoxon’s signed rank test and logistic regression. Results. Results showed that more children with epilepsy and their parents had inappropriate habits and attitudes towards oral health, as well as nutrition habits (p<0.001. Compared to healthy controls, children with epilepsy washed their teeth less often and shorter, they had less knowledge about causes of oral diseases and about influence of oral diseases on general health, and they had worse self-rating of teeth and gum condition. In addition, significantly more children with epilepsy used an incorrect technique of teeth brushing (p<0.001. Characteristics of children’s epilepsy and educational degree of parents had no influence on these differences. Conclusion. Study results showed that children with epilepsy and their parents had worse habits, attitudes and behavior towards oral health than healthy controls and their parents. This difference can be explained primarily by worse parental estimation of oral health and

    Summary This study was conducted to assess the efficacy of oral zinc supplementation in children with intractable epilepsy. Forty-five children aged between three and 12 years and diagnosed with idiopathic intractable epilepsy at Assiut University Hospital, Assiut, Egypt were recruited. The patients were randomly allocated to two groups: the intervention group received oral zinc supplementation (1 mg/kg/day) while the placebo group received placebo, each for six months. The parents of each child filled in a detailed questionnaire that covered demographic characteristics, type of seizures, frequency, duration of seizures, previous hospital admissions, postictal phenomena and the occurrence of status epilepticus. The primary outcome (frequency of seizures) was compared between the two groups. Zinc supplementation resulted in a significant reduction of seizure frequency in 31% of the treated children. Zinc is an important trace element. Our results suggest that it has mildly beneficial effects in children with intractable epilepsy. We recommend further investigation of oral zinc supplementation as an adjunctive therapy for managing intractable epilepsy in children. Zinc therapy may be an option in treatment protocols for intractable epilepsy in the near future. PMID:26415035

    The aim of this study was to evaluate the effects of the classic ketogenic diet (KD) on low-density lipoprotein (LDL) and high-density lipoprotein (HDL) subfractions in children and adolescents with refractory epilepsy. This prospective study recruited children and adolescents of either sex, whose epilepsy was refractory to treatment with multiple drugs. To be included, the patient had to have an indication for treatment with the KD and be treated as an outpatient. At baseline and after 3 and 6 mo of the KD, lipid profile (total cholesterol [TC], triacylglycerols [TG], LDL cholesterol [LDL-C], and HDL cholesterol [HDL-C]), apolipoproteins (apoA-I and apoB), 10 subfractions of HDL, 7 subfractions of LDL, LDL phenotype, and LDL size were analyzed using the Lipoprint system. The lipid profile components (TC, TG, LDL-C, HDL-C, apoA-I, and apoB) increased during the 3-mo follow-up, and remained consistent after 6 mo of treatment. Similarly, non-HDL-C, TC/HDL-C, LDL-C/HDL-C, and apoB/apoA-I ratios, representing atherogenic particles, significantly increased. In contrast, qualitative lipoprotein characteristics progressively changed during the follow-up period. Small LDL subfractions increased, and this profile was related with reduced LDL size (27.3 nm to 26.7 nm). The LDL phenotype became worse; 52.1% of the patients had a non-A phenotype after 6 mo of the KD. Small HDL subfractions decreased only after 6 mo of the KD. KD treatment promotes negative changes in lipoprotein size and phenotype, contributing to atherogenic risk in these patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    We describe the trends in antiepileptic drug (AED) use in children and adolescents with epilepsy in the United States. We undertook a cross-sectional study based on Medicaid Analytic eXtract data set from 26 US states. Children and adolescents aged three to 18 years with at least one year continuous Medicaid fee-for-service coverage after the second outpatient or the first inpatient diagnosis of epilepsy in each calendar year during 1999 to 2009 were included in the study; therefore, 11 cohorts were established. A patient was defined as being exposed to a specific AED if he or she had at least one-day supply of the AED during the 1-year follow-up period. The annual prevalence of AEDs was reported, stratified by gender and age. The trends in AED use were evaluated through linear regression. The sample sizes of the 11 cohorts ranged between 17,304 and 22,672. The annual prevalence of valproic acid use declined from 42.4% in 1999 to 26.5% in 2009, and the prevalence of carbamazepine use declined from 37.1% to 10.2%. Meanwhile, the prevalence of levetiracetam use increased from 5.1% to about 32.0% in 2009, and the prevalence of oxcarbazepine use increased from 1.3% to 19.1%. Since 2008, levetiracetam (29.6%) has replaced valproic acid (27.8%) as the most commonly used AED in children and adolescents with epilepsy. The prevalence of diazepam use increased from 11.6% to 28.1%. Compared with first- and second-generation antiepileptic drugs, third-generation AEDs have fewer adverse side effects, resulting in increased patient treatment adherence. Equally important is the economic impact of these newer AEDs. This first-of-its-kind study underscores the need for large database studies that objectively assess the cost-effectiveness of third-generation AEDs versus first- and second-generation AEDs in the treatment of childhood epilepsy.

    Full Text Available Convulsions triggered by fever are the most common type of seizures in childhood, and 20% to 30% of them have recurrence. The prophylactic treatment is still controversial, so we performed a systematic review to find out the effectiveness of continuous phenobarbital and intermittent diazepam compared to placebo for febrile seizure recurrence. METHOD: Only randomized, double-blind, placebo-controlled trials were analyzed. The recurrence of febrile seizure was assessed for each drug. RESULTS: Ten eligible clinical trials were included. Febrile seizure recurrence was smaller in children treated with diazepam or phenobarbital than in placebo group. Prophylaxis with either phenobarbital or diazepam reduces recurrences of febrile seizures. The studies were clinical, methodological, and statistically heterogeneous. CONCLUSION: The effectiveness of phenobarbital and diazepam could not be demonstrated because clinical trials were heterogeneous, and the recommendation for treatment recurrence should rely upon the experience of the assistant physician yet.

    The effect of phenobarbital on thyroid function and the metabolism and biliary excretion of thyroxine in rats was determined. Phenobarbital, administered for 2 weeks at a dose of 100 mg/kg/day, resulted in an increase in hepatic and thyroid gland weights, decreased circulating levels of T4, T3 and rT3, and increased TSH levels in male and female rats. After 3 months of treatment liver and thyroid weights were still increased; however, hormone values were not as markedly affected indicating that the rats had partially compensated for the effect on thyroid function. In thyroidectomized rats the plasma clearance of thyroxine was increased with phenobarbital. In bile duct cannulated phenobarbital-treated male rats the hepatic uptake at 4 hr was markedly increased. Bile flow was increased and the 4-hr cumulative biliary excretion of administered radioactivity was increased by 42%. Most of the increase in the excretion (76%) was accounted for by an increase in the excretion of thyroxine-glucuronide in phenobarbital-treated rats. Hepatic thyroxine-glucuronyltransferase activity in phenobarbital-treated rats expressed as picomoles per milligram of protein was increased by 40%; enzyme activity per gram of liver was increased by about twofold which, coupled with increased hepatic weight, resulted in about a threefold increase in total hepatic thyroxine-glucuronyltransferase activity in phenobarbital-treated rats as compared to that of controls. Qualitatively similar effects on metabolism, excretion, and enzyme induction were noted in female rats; however, the magnitude of increase was less than that observed in male rats. It is concluded that the effect of phenobarbital on thyroid function in rats is primarily a result of its effects on the hepatic disposition of thyroid hormone

    A single nucleotide substitution (c.-6-180T>G) associated with resistance to phenobarbital therapy has been found in the canine MDR1/ABCB1 gene in Border Collies with idiopathic epilepsy. In the present study, a PCR-restriction fragment length polymorphism assay was developed for genotyping this mutation, and a genotyping survey was carried out in a population of 472 Border Collies in Japan to determine the current allele frequency. The survey demonstrated the frequencies of the T/T wild type, T/G heterozygote, and G/G mutant homozygote to be 60.0%, 30.3%, and 9.8%, respectively, indicating that the frequency of the mutant G allele is extremely high (24.9%) in Border Collies. The results suggest that this high mutation frequency of the mutation is likely to cause a high prevalence of phenobarbital-resistant epilepsy in Border Collies.

    The most important adverse effects of phenobarbital, an anticonvulsant drug, are behavior and cognitive alterations. Hypersensitivity syndrome caused by phenobarbital presenting with a leukemoid reaction is a rare side effect, which is rarely ever reported and needs to be known. We report on a 27-year-old Chinese woman who experienced hypersensitivity syndrome three weeks after the initiation of phenobarbital. The patient developed fever, skin rash, face swelling, lymphadenopathy, myalgia, hepatitis, eosinophilia, atypical lymphocytes and leukocytosis. Along with the pathological progress of the disease, the patient noticed a gradual exacerbation of her symptoms. And the highest leukocyte count was up to 127.2 x 10(9)/L. After discontinuing of phenobarbital and administration of methylprednisolone combined with the intravenous immunoglobulin shock therapy, all initial symptoms improved and the leukocyte count normalized. This case is reported because of its rarity of the leukemoid reaction secondary to hypersensitivity syndrome to phenobarbital.

    Sudden unexplained/unexpected death (SUDEP) is related to high mortality in patients with epilepsy. The prolongation of QT interval, involved in cardiac arrhythmia-related SUDEP, may be precipitated by antiepileptic drugs (AEDs). In this study, we evaluated the effects of phenobarbital and levetiracetam on PR-QTc intervals in patients with post-stroke seizures. We performed an open-label, parallel group, prospective, multicenter study between June 2009 and December 2013 in patients older than 18 years of age with a clinical diagnosis of post-stroke seizure and treated with phenobarbital or levetiracetam. In order to exclude a role of cerebral post-stroke injury on modulation of PR and QTc intervals, patients with cerebral post-stroke injury and without seizures were also enrolled as controls. Interictal electrocardiography analysis revealed no significant difference in PR interval between patients treated with an AED (n = 49) and control patients (n = 50) (181.25 ± 12.05 vs. 182.4 ± 10.3 ms; p > 0.05). In contrast, a significantly longer QTc interval was recorded in patients treated with an AED compared with control patients (441.2 ± 56.6 vs. 396.8 ± 49.3 ms; p phenobarbital showed a significantly longer QTc interval than patients treated with levetiracetam (460.0 ± 57.2 vs. 421.5 ± 50.1 ms; p phenobarbital prolonged QTc interval more so than levetiracetam.

    We aimed to evaluate the health-related quality of life (HRQoL) of schoolchildren with epilepsy and its determinants and the HRQoL of their parents in comparison with those of healthy children and their parents. The study sample comprised 100 children with epilepsy (58 males), 8-16 years of age, diagnosed at least 6 months earlier. The children with epilepsy were divided into two subgroups: A, with well controlled idiopathic epilepsy, and B, with drug-resistant or symptomatic epilepsy and with concomitant neurodevelopmental problems. A control group consisted of 100 healthy age- and gender-matched children. One parent in each family completed two questionnaires standardized for use in Greece: KIDSCREEN-27 (version for parents) to assess the HRQoL of the children and SF-12 to assess the parental HRQoL. For each of the five dimensions of KIDSCREEN-27 and for the physical and mental component scales of the SF-12 tool, the standardized mean difference (SMD) was used for comparison between the various groups and subgroups. Linear regression analysis was used to explore the effect of specific illness-related factors on the five dimensions of KIDSCREEN-27 in the children with epilepsy. The parent-reported scores on KIDSCREEN-27 of the children with epilepsy were worse overall than those of healthy children, but the difference reached statistical significance only for the dimensions of "physical well-being" (p = 0.001) and "school environment" (p children with severe epilepsy, in the dimensions "physical well-being" (p children with resistant epilepsy and accompanying neurodevelopmental problems scored significantly worse on the SF-12 mental health scale than those of healthy children (p Epilepsy, particularly severe epilepsy with concomitant neurodevelopmental problems, adversely affects the HRQoL of both schoolchildren and their parents.

    To evaluate the psychological state of children with epilepsy and analyze its influencing factors. The Mental Health Scale for Child and Adolescent was used to survey 113 children with epilepsy and 114 normal children to evaluate and compare their psychological state. Questionnaires were used to investigate the general status of all subjects and the disease condition and treatment of children with epilepsy. The possible influencing factors for the psychological state of children with epilepsy were analyzed. The mental health status of children with epilepsy was poorer than that of normal children in cognition, thinking, emotion, will-behavior, and personality traits (Pchildren with epilepsy. There is a wider range of psychological health problems in children with epilepsy than in normal children. Poor family living environment, poor seizure control, and use of many antiepileptic drugs are the risk factors affecting the psychological state of children with epilepsy. Improving family living environment, controlling seizures, and monotherapy help to improve the psychological state of children with epilepsy.

    Epilepsy is a common neurological condition with a worldwide prevalence of around 1%. Approximately 60% to 70% of people with epilepsy will achieve a longer-term remission from seizures, and most achieve that remission shortly after starting antiepileptic drug treatment. Most people with epilepsy are treated with a single antiepileptic drug (monotherapy) and current guidelines from the National Institute for Health and Care Excellence (NICE) in the United Kingdom for adults and children recommend carbamazepine or lamotrigine as first-line treatment for partial onset seizures and sodium valproate for generalised onset seizures; however a range of other antiepileptic drug (AED) treatments are available, and evidence is needed regarding their comparative effectiveness in order to inform treatment choices. To compare the time to withdrawal of allocated treatment, remission and first seizure of 10 AEDs (carbamazepine, phenytoin, sodium valproate, phenobarbitone, oxcarbazepine, lamotrigine, gabapentin, topiramate, levetiracetam, zonisamide) currently used as monotherapy in children and adults with partial onset seizures (simple partial, complex partial or secondary generalised) or generalised tonic-clonic seizures with or without other generalised seizure types (absence, myoclonus). We searched the following databases: Cochrane Epilepsy's Specialised Register, CENTRAL, MEDLINE and SCOPUS, and two clinical trials registers. We handsearched relevant journals and contacted pharmaceutical companies, original trial investigators, and experts in the field. The date of the most recent search was 27 July 2016. We included randomised controlled trials of a monotherapy design in adults or children with partial onset seizures or generalised onset tonic-clonic seizures (with or without other generalised seizure types). This was an individual participant data (IPD) review and network meta-analysis. Our primary outcome was 'time to withdrawal of allocated treatment', and our secondary

    Full Text Available A single nucleotide substitution (c.-6-180T>G associated with resistance to phenobarbital therapy has been found in the canine MDR1/ABCB1 gene in Border Collies with idiopathic epilepsy. In the present study, a PCR-restriction fragment length polymorphism assay was developed for genotyping this mutation, and a genotyping survey was carried out in a population of 472 Border Collies in Japan to determine the current allele frequency. The survey demonstrated the frequencies of the T/T wild type, T/G heterozygote, and G/G mutant homozygote to be 60.0%, 30.3%, and 9.8%, respectively, indicating that the frequency of the mutant G allele is extremely high (24.9% in Border Collies. The results suggest that this high mutation frequency of the mutation is likely to cause a high prevalence of phenobarbital-resistant epilepsy in Border Collies.

    To examine the prevalence and clinical correlates of fatigue as an adverse event (AE) of antiepileptic drug (AED) treatment in patients with epilepsy. Data from 443 adult outpatients with epilepsy assessed with the Adverse Event Profile (AEP) and the Neurological Disorder Depression Inventory for Epilepsy (NDDIE) were analysed. Fatigue is reported by 36.6% of patients as always a problem during AED treatment. Fatigue is more likely to be reported by females (64.8% vs. 35.2%; Chi-Square=16.762; df=3; p=0.001) and during treatment with levetiracetam (42.3% vs. 33.2%; Chi-Square=11.462; df=3; p=0.009). The associations with the female gender and levetiracetam treatment were not mediated by depression, as identified with the NDDIE, and could not be simply explained by the large number of subjects on levetiracetam treatment, as analogous figures resulted from the analysis of a monotherapy subsample (41.7% vs. 30.3%; Chi-Square=11.547; df=3; p=0.009). One third of patients with epilepsy reports fatigue as a significant problem during AED treatment. Fatigue is more likely to be reported by females and seems to be specifically associated with LEV treatment. However, fatigue is not mediated by a negative effect of LEV on mood.

  5. The use of a formula-based ketogenic diet in children with refractory epilepsy

    Directory of Open Access Journals (Sweden)

    Letícia Pereira de Brito Sampaio

    Full Text Available ABSTRACT The ketogenic diet (KD is a nonpharmacologic treatment that has been used for refractory epilepsy since 1921. The KD is a high-fat, low-carbohydrate, and restricted protein diet, which is calculated and weighed for each individual patient. Introducing and maintaining the diet for a long time remains a challenge. In this study, we evaluated the acceptability, tolerance, and efficacy of a formula-based KD in 10 children with refractory epilepsy. The ketogenic formula tested herein caused only mild KD-related adverse events and adequate adherence. Moreover, 60% of patients had more than 50% seizure frequency reduction and 10% were seizure-free.

    Using several concentrations of eight anticonvulsant drugs in clinical use (carbamazepine, clonazepam, phenytoin, phenobarbital, ethosuximide, primidone, sodium valproate, and D,L-..gamma..-vinyl GABA), we studied their abilities in vitro to displace (/sup 35/S)t-butylbicyclophosphorothionate (/sup 35/S-TBPS) from its binding site in a homogenate of rat brain. Thereafter ethosuximide (150 mg/kg), phenobarbital (30 mg/kg), clonazepam (0.3 mg/kg), or phenytoin (100 mg/kg) was injected intraperitoneally into rats for 16-20 days; and the effect of drug administration on /sup 35/S-TBPS binding was studied in the cortex and hippocampus ex vivo. Phenobarbital (100 ..mu..M, P<0.001), ethosuximide (500 ..mu..M, P<0.001), and phenytoin (40 ..mu..M, P<0.001) decreased the specific /sup 35/S-TBPS binding in vitro by 10-16%. After drug administration of phenobarbital (concentration in plasma 168 ..mu..M), the number of binding sites decreased and the binding affinity (p<0.05) in the cortex increased. Other anticonvulsants did not modulate /sup 35/S-TBPS binding in vitro at the concentration analogous to therapeutic plasma levels or ex vivo at the dose used. These results suggest that the use of phenobarbital may modulate the TBPS binding site, but the role of the present findings in the anticonvulsant action of phenobarbital needs to be further studied.

    Full Text Available We describe a treatment alternative for intractable, startle-provoked, epileptic seizures in four children aged between 8 and 14. Three of the four children had symptomatic localization-related epilepsy. They all suffered from intractable epilepsy precipitated by sudden sounds. The fact that seizures tended to occur with high frequency – more than one seizure a day – had a clear impact on daily life. Clinical seizure pattern demonstrated asymmetric tonic posturing in all four children. Three children experienced several seizure types including focal seizure onset. All children had focal neurological signs or learning disabilities or a combination of both. Our noninvasive treatment method using psychoeducational counseling and sound generators was applied in four children, resulting in a seizure frequency reduction of ≥50% in two of them.

    Ideal epilepsy surgery would eliminate seizures without causing any functional deficits. The aim of the present study was to assess seizure outcomes and complications after epilepsy surgery in children with intractable epilepsy. Data obtained in 134 children (75 boys and 59 girls) age 17 years or younger who underwent epilepsy surgery at Seoul National University Children's Hospital between 1993 and 2005 were retrospectively reviewed. Epilepsy surgery included temporal resection (59 cases), extratemporal resection (56 cases), functional hemispherectomy (7 cases), callosotomy (9 cases), multiple subpial transection (1 case), and disconnection of a hamartoma (2 cases). The mean follow-up duration was 62.3 months (range 12-168 months). The overall seizure-free rate was 69% (93 of 134 cases). The seizure-free rate was significantly higher in children who underwent temporal resection than in those in whom extratemporal resection was performed (88 vs 55%, p surgery is an effective and safe therapeutic modality in childhood. In children with extratemporal epilepsy, more careful interpretation of clinical and investigative data is needed to achieve favorable seizure outcome.

    The ketogenic diet is an alternative treatment for patients with refractory epilepsy. Most studies to date report dietary response in children. There are limited data evaluating the efficacy of the ketogenic diet in adults. This is a report of the long-term outcome in a largely adult population of patients treated with the ketogenic diet for epilepsy. Twenty-nine adult and adolescent patients (mean age 32 years, range 11-51) were initiated on the ketogenic diet and followed until diet discontinuation. Clinical response and adverse effects were noted during the duration of the diet. Fifty-two percent of patients had a significant reduction in seizure frequency on the ketogenic diet, including 45% with ≥50% reduction in seizure frequency. Thirty-one percent had no improvement, seven percent were unable to successfully initiate the diet, and 10% had a >50% increase in seizure frequency. The diet was continued for a mean of 9 months (range 0.13-35 months), with five patients completing ≥23 months. There was a trend toward better response and better tolerability/longer duration in patients with symptomatic generalized epilepsy. The diet was generally well-tolerated, but undesired weight loss and constipation were the most frequent adverse effects. The ketogenic diet can be used safely in the adult and adolescent population, with a response rate similar to those seen in children. Patient with symptomatic generalized epilepsy may be particularly good candidates for this type of dietary treatment. Copyright © 2014 British Epilepsy Association. Published by Elsevier Ltd.

    Full Text Available Background: Refractory status epilepticus usually defined as a seizure lasting at least 60 minutes which is uncontrollable by Diazepam, Phenytoin, or Phenobarbital. The aim of this study was to compare the effect of interavenous Midazolam and rectal Sodium valproate in controlling refractory status epilepticus. Methods: In this case-control study; 76 children with (mean age of 37± 20 months with refractory status epilepticus were randomly divided into two groups to receive IV Midazolam and rectal Sodium Valproate. The effect of the two drugs were compared in control of seizure during first 20 minutes of treatment. Results: In 84.2 percent of children treated with IV Midazolam, the seizure was under control within 4.5 ± 0.5 minutes, while in 63 percent of those receiving Sodium Valproate, the seizure was completely controlled within 16.5 ± 0.8 minutes (P < 0.00001. Conclusion: The IV Midazolam was more effective than Sodium valproate, but the latter can be used in hospitals or pediatric emergency wards without ICU for controlling of refractory status epilepticus. Key words: refractory status epilepticus, midazolam, sodium valproate

    Full Text Available The alteration of cytokine balance is stated to exert greater influence on gingival overgrowth compared to the direct effect of the drug on the regulation of extracellular matrix metabolism. The current study evaluated the effect of phenytoin on the regulation of collagen, lysyl oxidase and elastin in gingival fibroblasts.Normal human gingival fibroblasts (HGFs were obtained from 4 healthy children and 4 adults. Samples were cultured with phenytoin. MTT test was used to evaluate the proliferation and ELISA was performed to determine the level of IL1β and PGE2 production by HGFs. Total RNA of gingival fibroblasts was extracted and RT-PCR was performed on samples. Mann-Whitney U test was used to analyze the data with an alpha error level less than 0.05.There was a significant difference in the expression of elastin between the controls and treated samples in both adult and pediatric groups and also in the lysyl oxidase expression of adult controls and treated adults. No significant difference was found between collagen expression in adults.The significant difference in elastin and lysyl oxidase expression between adult and pediatric samples indicates the significant effect of age on their production.

    The diagnosis of epilepsy can lead to changes in the patient's perception due to factors such as learning and behavioral problems, lack of academic motivation, and low self-esteem. This study aimed to evaluate and compare the knowledge of self-concept in children with epilepsy and those with typical development and verify whether gender and age influence this perception. Eighty children of both sexes, aged between 8 and 14years, participated in this study. The children were divided into two groups: the epilepsy group, which consisted of 40 children diagnosed with epilepsy, and the control group, which consisted of 40 children with typical development and comparable to group 1 according to sex and age. The Piers-Harris Children's Self-Concept Scale, translated and adapted for the Brazilian population, was used as the evaluation instrument. In total, there were 23 boys and 17 girls in each group, with a mean age of 10.7years. There were significant differences in the overall score (p=0.000) and the subareas "behavior" (p=0.006), "intellectual and academic status" (p=0.001), and "popularity" (p=0.004). The group of children with epilepsy had a lower average score in self-concept. Children with epilepsy were observed to perceive themselves as clumsy, without many friends, with low academic performance and problems at school, and to experiencing feelings of unhappiness. These findings suggest that, in addition to the treatment of the clinical manifestations of epilepsy, it is extremely important to provide treatment focused on improving the self-concept of school-aged children with this condition.

    The aim of the study was to compare sleep patterns in children with epilepsy with those of their non-epileptic siblings and to determine which epilepsy-specific factors predict greater sleep disturbance. We conducted a case-control study of 55 children with epilepsy (mean age 10y, range 4 to 16y; 27 males, 28 females) and their nearest-aged non-epileptic sibling (mean age 10y, range 4 to 18y; 26 males, 29 females). Epilepsy was idiopathic generalized in eight children (15%), symptomatic generalized in seven (13%), and focal in 40 (73%); the mean duration was 5 years 8 months. Parents or caregivers completed the Sleep Behavior Questionnaire (SBQ) and Child Behavior Checklist (CBCL) for patients and controls, and the Quality of Life in Childhood Epilepsy (QOLCE) for patients. Patients had a higher (more adverse) Total Sleep score (p<0.001) and scored worse than controls on nearly all subscales of the SBQ. In patients, higher Total Sleep scores were correlated with higher scores on the Withdrawn, Somatic complaints, Social problems, and Attention subscales of the CBCL, and significantly lower Total Quality of Life Scores. Refractory epilepsy, mental retardation, and remote symptomatic etiology predicted greater sleep problems in those with epilepsy. We conclude that children with epilepsy in this current study had significantly greater sleep problems than their non-epileptic siblings.

    The purpose of this study was to explore the lived experiences of school-aged children with epilepsy in Taiwan. Epilepsy affects many people worldwide, especially school-aged children, but few studies have examined children's viewpoints of their experiences with epilepsy. An exploratory, phenomenological interview design was used. Children (ages 7-12 years) with well-controlled epilepsy and no developmental delay were recruited from a hospital in central Taiwan. Data were collected from 15 children using a semi-structured interview guide. Interviews were tape-recorded with permission from parents and children. Verbatim transcripts were analysed using Colazzi's phenomenological method. Two themes emerged from the analysis. The first theme, 'living with epilepsy', had two subthemes: disease-related experiences and school-related issues. The second theme, 'coping with epilepsy', had two subthemes: developing strategies to manage or reduce seizures and seeking support from family members. Taiwanese children with epilepsy had similar lived experiences as their counterparts in Western culture, e.g. unpleasant somatic symptoms, difficulty learning and troubled peer relationships. Taiwanese children also coped similarly with epilepsy by taking medications to control seizures, but they differed from their Western counterparts in trying to self-manage seizures and seeking support from family members. Public health and school nurses can apply our findings to educate school teachers and parents about epilepsy and encourage activities that allow children with and without epilepsy to interact, thus improving peer relationships and reducing stigmatisation. Children with and without epilepsy would also benefit from an age-appropriate education manual that includes causes of epilepsy, treatment, dealing with seizures and psychological and social adaptation.

  16. Clinical Pharmacology of Phenobarbital in Neonates: Effects, Metabolism and Pharmacokinetics.

    Pacifici, Gian M

    2016-01-01

    Phenobarbital is an effective and safe anticonvulsant drug introduced in clinical use in 1904. Its mechanism of action is the synaptic inhibition through an action on GABAA. The loading dose of phenobarbital is 20 mg/kg intravenously and the maintenance dose is 3 to 4 mg/kg by mouth. The serum concentration of phenobarbital is up to 40 µg/ml. Nonresponders should receive additional doses of 5 to 10 mg/kg until seizures stop. Infants with refractory seizures may have a serum concentration of phenobarbital of 100 µg/ml. Phenobarbital is metabolized in the liver by CYP2C9 with minor metabolism by CYP2C19 and CYP2E1. A quarter of the dose of phenobarbital is excreted unchanged in the urine. In adults, the half-life of phenobarbital is 100 hours and in term and preterm infants is 103 and 141 hours, respectively. The half-life of phenobarbital decreases 4.6 hours per day and it is 67 hours in infants 4 week old.

    The early and late benign occipital epilepsies of childhood (BOEC) are described as two discrete electro-clinical syndromes, eponymously known as Panayiotopoulos and Gastaut syndromes. The purpose of this study was to identify predictors of failure to respond to the initial antiepileptic drug (AED). A total of 42 children with BOEC were enrolled. Predictive factors were analyzed by survival methods. Among the 42, 25 patients (59.5%) were boys and 17 (40.5%) were girls and the mean age at the seizure onset was 7.46 ± 2.65 years (4-14 years). Of the 42 patients, 34 (81.0%) were treated relatively successfully with the first AED treatment, and 8 (19.0%) were not responded initial AED treatment. There was no correlation between response to initial AED treatment and sex, consanguinity, epilepsy history of family, age of seizure onset, frequency of seizures, history of status epilepticus, duration of starting first treatment, findings on electroencephalogram. However, history of febrile seizure and type of BOEC were significantly associated with failure risk. Factors predicting failure to respond to the AED were history of febrile seizure and type of BOEC in children with BOEC.

    Phenobarbital is the first-line treatment for neonatal seizures. Many neonates with hypoxic ischemic encephalopathy are treated with therapeutic hypothermia, and about 40% have clinical seizures. Little is known about the pharmacokinetics of phenobarbital in infants with hypoxic ischemic encephalopathy who undergo therapeutic hypothermia. The objective of this study was to determine the effect of therapeutic hypothermia on phenobarbital pharmacokinetics, taking into account maturational changes. Level 3 neonatal ICU. Infants with hypoxic ischemic encephalopathy and suspected seizures, all treated with phenobarbital. Some of these infants also received treatment with therapeutic hypothermia. None. A retrospective cohort study of 39 infants with hypoxic ischemic encephalopathy treated with phenobarbital (20 were treated with therapeutic hypothermia and 19 were not). Data on phenobarbital plasma concentrations were collected in 39 subjects with hypoxic ischemic encephalopathy with or without therapeutic hypothermia. Using nonlinear mixed-effects modeling, population pharmacokinetics of phenobarbital were developed with a total of 164 plasma concentrations. A one-compartment model best described the pharmacokinetics. The clearance of phenobarbital was linearly related to body weight and matured with increasing age with a maturation half-life of 22.1 days. Therapeutic hypothermia did not influence the pharmacokinetic parameters of phenobarbital. Therapeutic hypothermia does not influence the clearance of phenobarbital after accounting for weight and age. Standard phenobarbital dosing is appropriate for the initial treatment of seizures in neonates with hypoxic ischemic encephalopathy treated with therapeutic hypothermia.

    Full Text Available Objective: To emphasize the importance of early diagnosis and treatment on the prognosis of children with epilepsy accompanied by continuous spikes and waves during slow wave sleep (CSCW. Methods: The clinical characteristics, electroencephalogram (ECG features, treatment and prognosis of 12 children with CSCW in our hospital were retrospectively analyzed, and the followup of 6 months to 4 years was given. Results: Imaging showed that 8 children suffered from brain lesions, while other 4 were normal. The initial onset of 10 children was at night, whereas 2 began with absence seizure in lucid interval, and they gradually appeared comprehensive brain function decline, meanwhile, ECG was characterized by continuous discharge during slow wave sleep. After 3 months of treatment with valproic acid, clonazepam, lamotrigine and hormones, the clinical symptoms and ECG of 10 children improved significantly, in which 3 ones recurred after 6 months of comprehensive treatment. Conclusion: The early manifestation of CSWS is untypical, and hence, early diagnosis and treatment can ameliorate the epileptic seizures of children, effectively inhibit epileptic electrical activity and has favorable prognosis.

    The aim of this study was to compare two neuroprotective strategies to supportive care in the treatment of perinatal asphyxia. A total of 67 term newborns with perinatal asphyxia were included and randomized into three groups: one group received supportive treatment; another group received a single dose of 40 mg/kg phenobarbital; and the third received three daily doses of 1000 IU/kg erythropoietin. The following parameters were analyzed: gestational age, birthweight, Apgar scores, cord blood pH, total serum antioxidant status (TAS), superoxide dismutase (SOD), glutathione peroxidase (GPx) and malondialdehyde (MDA). The newborns were included in the follow-up program and examined up to 18 months of age. TAS was higher in the erythropoietin group than in the other groups. SOD and GPx were lower for infants treated with phenobarbital or erythropoietin compared to control infants. MDA was lower in the erythropoietin group compared to the other groups, although the difference was not statistically significant (P > 0.05). The mortality rate was lower in the phenobarbital and erythropoietin groups (both 4.6%) than in the control group (17.4%). Long-term neurologic follow up showed a high incidence of sequelae in the control group compared to the phenobarbital and erythropoietin groups. Follow-up results were better in the phenobarbital group than in the erythropoietin group for motor and cognitive function at 3 and 6 months and worse for expressive language. At 18 months, however, the differences between these two groups were not significant. High-dose phenobarbital or erythropoietin along with supportive treatment has a positive influence on the outcome of newborns with perinatal asphyxia. Phenobarbital has the advantage of low cost and simplicity. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

    Full Text Available Tics are the most common forms of hyperkinesis among children and adolescents, the etiology of which is not fully clear. A study has shown a high comorbidity of tic disorders and epilepsy, as evidenced by video-EEG monitoring. In patients with tics even in the absence of epileptic seizures, epileptiform activity is an adverse predictor and a determinant of the potential risk of comorbid epilepsy especially during neuroleptic therapy. Antiepileptic drugs are the drugs of choice to treat this category of patients.

    To examine baseline psychological functioning and antiepileptic drug (AED) behavioral side effects in new onset epilepsy and determine, by age, whether baseline psychological functioning predicts AED behavioral side effects 1 month following AED initiation. A retrospective chart review was conducted between July 2011 and December 2014 that included youths with new onset epilepsy. As part of routine interdisciplinary care, caregivers completed the Behavior Assessment System for Children, 2nd Edition: Parent Rating Scale to report on baseline psychological functioning at the diagnostic visit and the Pediatric Epilepsy Side Effects Questionnaire to identify AED behavioral side effects at the 1-month follow-up clinic visit following AED initiation. Children (age = 2-11 years) and adolescents (age = 12-18 years) were examined separately. A total of 380 youths with new onset epilepsy (M age  = 8.9 ± 4.3 years; 83.4% Caucasian; 34.8% focal epilepsy, 41.1% generalized epilepsy, 23.7% unclassified epilepsy) were included. Seventy percent of youths had at-risk or clinically elevated baseline psychological symptoms. Children had significantly greater AED behavioral side effects (M = 25.08 ± 26.36) compared to adolescents (M = 12.36 ± 17.73), regardless of AED. Valproic acid demonstrated significantly greater behavioral side effects compared to all other AEDs, with the exception of levetiracetam. Higher hyperactivity/impulsivity at baseline significantly predicted higher AED behavioral side effects 1 month after AED initiation in both age groups. Younger children seem to be more prone to experience behavioral side effects, and these are likely to be higher if youths with epilepsy have baseline hyperactivity/impulsivity. Baseline psychological screening, specifically hyperactivity, can be used as a precision medicine tool for AED selection. Wiley Periodicals, Inc. © 2017 International League Against Epilepsy.

  3. Animal Models of Seizures and Epilepsy: Past, Present, and Future Role for the Discovery of Antiseizure Drugs.

    Löscher, Wolfgang

    2017-07-01

    The identification of potential therapeutic agents for the treatment of epilepsy requires the use of seizure models. Except for some early treatments, including bromides and phenobarbital, the antiseizure activity of all clinically used drugs was, for the most part, defined by acute seizure models in rodents using the maximal electroshock and subcutaneous pentylenetetrazole seizure tests and the electrically kindled rat. Unfortunately, the clinical evidence to date would suggest that none of these models, albeit useful, are likely to identify those therapeutics that will effectively manage patients with drug resistant seizures. Over the last 30 years, a number of animal models have been developed that display varying degrees of pharmacoresistance, such as the phenytoin- or lamotrigine-resistant kindled rat, the 6-Hz mouse model of partial seizures, the intrahippocampal kainate model in mice, or rats in which spontaneous recurrent seizures develops after inducing status epilepticus by chemical or electrical stimulation. As such, these models can be used to study mechanisms of drug resistance and may provide a unique opportunity for identifying a truly novel antiseizure drug (ASD), but thus far clinical evidence for this hope is lacking. Although animal models of drug resistant seizures are now included in ASD discovery approaches such as the ETSP (epilepsy therapy screening program), it is important to note that no single model has been validated for use to identify potential compounds for as yet drug resistant seizures, but rather a battery of such models should be employed, thus enhancing the sensitivity to discover novel, highly effective ASDs. The present review describes the previous and current approaches used in the search for new ASDs and offers some insight into future directions incorporating new and emerging animal models of therapy resistance.

    The goal of this study was to investigate how the disease and treatment of epilepsy affected the psychological profile (depression and anxiety) of mothers whose children had epilepsy, as well as these mothers' attitudes towards their children and their family relationships. Both the case and control groups consisted of 50 children and their mothers. All mothers were asked to complete the Beck Depression Inventory, State-Trait Anxiety Inventory, Parental Attitude Research Instrument and Family Assessment Device. Mothers whose children had epilepsy scored significantly higher in depression and state anxiety compared to the mothers of the control group. The mothers of children diagnosed with epilepsy also failed to develop supportive and friendly relationships with their children. In addition, these mothers scored significantly higher in the Attitude of Hostility and Rejection, Marital Discordance and Authoritarian Attitude as compared to the mothers of the control group. This cross-sectional study demonstrated that, for the mothers of children who had epilepsy, the illness might have an adverse effect on their lives and their family relationships.

    Children with hydrocephalus are at risk for epilepsy both due to their underlying condition and as a consequence of surgical treatment; however, the relative contributions of these factors remain unknown. The authors sought to characterize epilepsy among children with infancy-onset hydrocephalus and to examine the risks of epilepsy associated with hydrocephalus subtype and with factors related to surgical treatment. We conducted a longitudinal cohort study of all children with infancy-onset hydrocephalus treated at a major regional children's hospital during 2002 to 2012, with follow-up to ascertain risk factors and epilepsy outcome through April 2015. Poisson regression was used to calculate adjusted risk ratios and 95% confidence intervals for associations. Among 379 children with hydrocephalus, 86 (23%) developed epilepsy (mean onset age = 2.7 years), almost one fifth of whom had a history of infantile spasms. Relative to spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes had fourfold higher risks of developing epilepsy. Among children who underwent surgery, surgical infection doubled the risk of epilepsy (risk ratio = 2.0, 95% confidence interval = 1.4 to 3.0). Epilepsy was associated with surgical failure for intracranial reasons but not extracranial reasons (risk ratio = 1.7, 95% confidence interval = 1.1 to 2.7; risk ratio = 1.1, 95% confidence interval = 0.7 to 1.9, respectively). Epilepsy is common among children with hydrocephalus. Compared with children with spina bifida-associated hydrocephalus, children with other major hydrocephalus subtypes have a markedly increased risk of epilepsy. Surgical infection doubles the risk of epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Researchers document the emotional impact of epilepsy on the child with seizures. Minimal data are available examining the effects of epilepsy on the siblings of children with seizures. Twenty children whose siblings had either frequent seizures or infrequent seizures were matched by age, gender, and birth order to control subjects with no chronic illness. These three groups were compared. Self-esteem, behavioral and social functioning, and family stress were measured by the Piers-Harris Self-Concept Scale, Child Behavior Checklist, and Family Inventory of Life Events. The siblings of children with epilepsy completed the Sibling Concern About Seizure Scale to define and measure their concerns surrounding epilepsy. There is no statistical difference in self-esteem or social functioning among the three groups. There is a trend toward increased incidence of externalizing behavior in siblings of children with frequent seizures. Data indicate a trend toward siblings of children with frequent seizures having more concerns about epilepsy than siblings of children with infrequent seizures. There is significantly more stress in families of children with frequent seizures compared to families of children with infrequent seizures and families of children with no chronic illness. Although there were no significant differences in the self-esteem, behavior, socialization, and concerns between the siblings in the family when compared to the control group or to each other, there were trends in the results that may be of clinical significance. These issues, along with the level of family stress, should be considered when coordinating and providing care to families of children with intractable epilepsy.

    We report the results of administration of the Portuguese-Brazilian translation of the Liverpool Adverse Events Profile (LAEP) to 100 patients (mean age=34.5, SD=12.12; 56 females), 61 with symptomatic partial epilepsy (SPE) and 39 with idiopathic generalized epilepsy (IGE) (ILAE, 1989) who were on a stable antiepileptic drug (AED) regimen and being treated in a Brazilian tertiary epilepsy center. Carbamazepine was the most commonly used AED (43.0%), followed by valproic acid (32.0%). Two or more AEDs were used by 69.0% of patients. The mean LAEP score (19 questions) was 37.6 (SD=13.35). The most common adverse effects were sleepiness (35.0%), memory problems (35.0%), and difficulty in concentrating (25.0%). Higher LAEP scores were associated with polytherapy with three or more AEDs (P=0.005), female gender (P0.001) and Hospital Anxiety and Depression Scale (Depression: r=0.637, P<0.001; Anxiety: r=0.621, P<0.001) dimensions. LAEP overall scores were similar in people with SPE and IGE and were not helpful in differentiating adverse effects in these two groups. Clinical variables that influenced global LAEP were seizure frequency (P=0.050) and generalized tonic-clonic seizures in the last month (P=0.031) in the IGE group, and polytherapy with three or more AEDs (P=0.003 and P=0.003) in both IGE and SPE groups.

    The ketogenic diet (KD) has been referred to as an "effective therapy with side effects" for children with intractable epilepsy. Among the most recognized adverse effects, there are cardiac conduction abnormalities, vascular and myocardial dysfunction. However, very limited and controversial data are available regarding the effects of the KD on cardiac functions. We sought to analyze the mid-term effect of ketogenic diet on cardiac functions in patients with intractable epilepsy who received a ketogenic diet for at least 12months using conventional and relatively new imaging techniques. This prospective study included 61 patients with intractable epilepsy who received ketogenic diet for at least 12months. Clinical examinations, serum carnitine and selenium levels as well as electrocardiographic and echocardiographic examinations were scheduled prior to the procedure and at 1, 3, 6 and 12months. We utilized two-dimensional, M-mode, colored Doppler, spectral Doppler and pulsed wave tissue Doppler imaging techniques to investigate ventricular systolic and diastolic functions of this subgroup of patients. In our study, there was no significant difference after 1year of KD therapy compared to baseline values-except a significantly decreased A wave velocity-in terms of pulse wave Doppler echocardiographic measurements of the diastolic function. The tissue Doppler measurements obtained from the lateral wall of tricuspide and mitral annuli were not different at baseline and at month 12 of the treatment, as well. The ketogenic diet appears to have no disturbing effect on ventricular functions in epileptic children in the midterm. Copyright © 2016 The Japanese Society of Child Neurology.

    Evaluation of quality of life has become a frequently used method in treatment effects supervision. Quality of Life Childhood Epilepsy (QOLCE) questionnaire, which is completed by patients' parents, has been prepared for children with epilepsy. It enables to determine the quality of life in children aged 4-18 years. The aim of the study was to show the usefulness of QOLCE questionnaire in evaluating the quality of life of children with epilepsy. 160 epileptic children, aged 8-18 years and their parents were examined in the Chair and Department of Developmental Neurology, K. Marcinkowski University of Medical Sciences in Poznań. QOLCE questionnaire was completed by parents and "Young people and epilepsy" questionnaire was designed for children. Reliability index of the complete questionnaire in own research and in the original amounted to 0.93 Cronbach alpha coefficient. Epileptic, drug-resistant children constituted 28% of the examined group. Parents of children with controlled seizures evaluated children's functioning in analyzed areas of quality of life higher. 1. QOLCE questionnaire is a suitable tool to evaluate the quality of children's and adolescents' life. 2. The most significant differences in functioning of epileptic, drug-resistant patients and those with controlled seizures were observed in areas of cognitive processes and social activity.

    Full Text Available Epilepsy adversely affects the health-related quality of life (HRQoL of children living with it. Even though almost 80% of children with epilepsy live in developing countries very little research has been conducted with the specific population. The present study took place in Albania and aimed to investigate parental perceptions of the HRQoL of their children with epilepsy. Considering the well-defined gender roles in the Albanian traditional family it was expected that mothers and fathers reports of their children’s HRQoL would differ. Results showed no differences in maternal and paternal reports; instead there was a moderate correspondence between the reports across all dimensions. Parents also reported the highest scores of HRQoL in the interpersonal dimension and the lowest scores in the intrapersonal dimension. The findings have implications in the context of future research and also medical care for children with epilepsy in Albania.

    Severe childhood epilepsies are characterized by frequent seizures, neurodevelopmental delays, and impaired quality of life. In these treatment-resistant epilepsies, families often seek alternative treatments. This survey explored the use of cannabidiol-enriched cannabis in children with treatment-resistant epilepsy. The survey was presented to parents belonging to a Facebook group dedicated to sharing information about the use of cannabidiol-enriched cannabis to treat their child's seizures. Nineteen responses met the following inclusion criteria for the study: a diagnosis of epilepsy and current use of cannabidiol-enriched cannabis. Thirteen children had Dravet syndrome, four had Doose syndrome, and one each had Lennox-Gastaut syndrome and idiopathic epilepsy. The average number of antiepileptic drugs (AEDs) tried before using cannabidiol-enriched cannabis was 12. Sixteen (84%) of the 19 parents reported a reduction in their child's seizure frequency while taking cannabidiol-enriched cannabis. Of these, two (11%) reported complete seizure freedom, eight (42%) reported a greater than 80% reduction in seizure frequency, and six (32%) reported a 25-60% seizure reduction. Other beneficial effects included increased alertness, better mood, and improved sleep. Side effects included drowsiness and fatigue. Our survey shows that parents are using cannabidiol-enriched cannabis as a treatment for their children with treatment-resistant epilepsy. Because of the increasing number of states that allow access to medical cannabis, its use will likely be a growing concern for the epilepsy community. Safety and tolerability data for cannabidiol-enriched cannabis use among children are not available. Objective measurements of a standardized preparation of pure cannabidiol are needed to determine whether it is safe, well tolerated, and efficacious at controlling seizures in this pediatric population with difficult-to-treat seizures. © 2013.

  12. Neuroendocrine considerations in the treatment of men and women with epilepsy

    Harden, Cynthia L; Pennell, Page B

    2016-01-01

    Complex, multidirectional interactions between hormones, seizures, and the medications used to control them can present a challenge for clinicians treating patients with epilepsy. Many hormones act as neurosteroids, modulating brain excitability via direct binding sites. Thus, changes in endogenous or exogenous hormone levels can affect the occurrence of seizures directly as well as indirectly through pharmacokinetic effects that alter the concentrations of antiepileptic drugs. The underlying structural and physiological brain abnormalities of epilepsy and the metabolic activity of antiepileptic drugs can adversely affect hypothalamic and gonadal functioning. Knowledge of these complex interactions has increased and can now be incorporated in meaningful treatment approaches for men and women with epilepsy. PMID:23237902

    The epilepsy treatment gap is largest in resource-poor countries. We evaluated the efficacy of a 1-day health education program in a rural area of Kenya. The primary outcome was adherence to antiepileptic drugs (AEDs) as measured by drug levels in the blood, and the secondary outcomes were seizure frequency and Kilifi Epilepsy Beliefs and Attitudes Scores (KEBAS). Seven hundred thirty-eight people with epilepsy (PWE) and their designated supporter were randomized to either the intervention (education) or nonintervention group. Data were collected at baseline and 1 year after the education intervention was administered to the intervention group. There were 581 PWE assessed at both time points. At the end of the study, 105 PWE from the intervention group and 86 from the nonintervention group gave blood samples, which were assayed for the most commonly used AEDs (phenobarbital, phenytoin, and carbamazepine). The proportions of PWE with detectable AED levels were determined using a standard blood assay method. The laboratory technicians conducting the assays were blinded to the randomization. Secondary outcomes were evaluated using questionnaires administered by trained field staff. Modified Poisson regression was used to investigate the factors associated with improved adherence (transition from nonoptimal AED level in blood at baseline to optimal levels at follow-up), reduced seizures, and improved KEBAS, which was done as a post hoc analysis. This trial is registered in ISRCTN register under ISRCTN35680481. There was no significant difference in adherence to AEDs based on detectable drug levels (odds ratio [OR] 1.46, 95% confidence interval [95% CI] 0.74-2.90, p = 0.28) or by self-reports (OR 1.00, 95% CI 0.71-1.40, p = 1.00) between the intervention and nonintervention group. The intervention group had significantly fewer beliefs about traditional causes of epilepsy, cultural treatment, and negative stereotypes than the nonintervention group. There was no

    Despite the over 20 antiepileptic drugs (AEDs) now licensed for epilepsy treatment, seizures can be effectively controlled in about ∼70% of patients. Thus, epilepsy treatment is still challenging in about one third of patients and this may lead to a severe medically, physically, and socially disabling condition. However, there is clear evidence of heterogeneity of response to existing AEDs and a significant unmet need for effective intervention. A number of studies have shown that polymorphisms may influence the poor or inadequate therapeutic response as well as the occurrence of adverse effects. In addition, the new frontier of genomic technologies, including chromosome microarrays and next-generation sequencing, improved our understanding of the genetic architecture of epilepsies. Recent findings in some genetic epilepsy syndromes provide insights into mechanisms of epileptogenesis, unrevealing the role of a number of genes with different functions, such as ion channels, proteins associated to the vesical synaptic cycle or involved in energy metabolism. The rapid progress of high-throughput genomic sequencing and corresponding analysis tools in molecular diagnosis are revolutionizing the practice and it is a fact that for some monogenic epilepsies the molecular confirmation may influence the choice of the treatment. Moreover, the novel genetic methods, that are able to analyze all known genes at a reasonable price, are of paramount importance to discover novel therapeutic avenues and individualized (or precision) medicine.

    Most individuals with epilepsy will respond to pharmacologic treatment; however, approximately 20-30% will develop medically refractory epilepsy. Cognitive side effects of antiepileptic drugs are common and can negatively affect tolerability, compliance, and long-term retention of the treatment. Ketogenic diet is an effective and well-tolerated treatment for these children with refractory epilepsy without any negative effect on cognition or behavior. To review the current state of experimental and clinical data concerning the neuroprotective and cognitive effects of the ketogenic diet in both humans and animals. In different animal models, with or without epilepsy, the ketogenic diet seems to have neuroprotective and mood-stabilizing effects. In the observational studies in pediatric epilepsy, improvements during treatment with the ketogenic diet are reported in behavior and cognitive function, particularly with respect to attention, alertness, activity level, socialization, and sleep quality. One randomized controlled trial in patients with pediatric refractory epilepsy showed a mood and cognitive activation during ketogenic diet treatment. Ketogenic diet shows a positive impact on behavioral and cognitive functioning in children and adolescents with refractory epilepsy. More specifically, an improvement is observed in mood, sustained attention, and social interaction.

    To describe the experience of five Israeli pediatric epilepsy clinics treating children and adolescents diagnosed as having intractable epilepsy with a regimen of medical cannabis oil. A retrospective study describing the effect of cannabidiol (CBD)-enriched medical cannabis on children with epilepsy. The cohort included 74 patients (age range 1-18 years) with intractable epilepsy resistant to >7 antiepileptic drugs. Forty-nine (66%) also failed a ketogenic diet, vagal nerve stimulator implantation, or both. They all started medical cannabis oil treatment between 2-11/2014 and were treated for at least 3 months (average 6 months). The selected formula contained CBD and tetrahydrocannabinol at a ratio of 20:1 dissolved in olive oil. The CBD dose ranged from 1 to 20mg/kg/d. Seizure frequency was assessed by parental report during clinical visits. CBD treatment yielded a significant positive effect on seizure load. Most of the children (66/74, 89%) reported reduction in seizure frequency: 13 (18%) reported 75-100% reduction, 25 (34%) reported 50-75% reduction, 9 (12%) reported 25-50% reduction, and 19 (26%) reported CBD withdrawal. In addition, we observed improvement in behavior and alertness, language, communication, motor skills and sleep. Adverse reactions included somnolence, fatigue, gastrointestinal disturbances and irritability leading to withdrawal of cannabis use in 5 patients. The results of this multicenter study on CBD treatment for intractable epilepsy in a population of children and adolescents are highly promising. Further prospective, well-designed clinical trials using enriched CBD medical cannabis are warranted. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    Phenobarbital is an old antiepileptic drug used in severe epilepsy. Despite this, little is written about the need for dose adjustments in renal replacement therapy. Most sources recommend a moderately increased dose guided by therapeutic drug monitoring.A 14 year old boy with nonketotic hyperglycinemia, a rare inborn error of metabolism, characterized by high levels of glycine, epilepsy, spasticity, and cognitive impairment, was admitted to the emergency department with respiratory failure after a few days of fever and cough. The boy was unconscious at admittance and had acute renal and hepatic failure.Due to the acute respiratory infection, hypoxic hepatic and renal failure occurred and the patient had a status epilepticus.The patient was intubated and mechanically ventilated. Continuous renal replacement therapy was initiated. Despite increased phenobarbital doses, therapeutic levels were not reached until the dose was increased to 500 mg twice daily. Therapeutic drug monitoring was performed in plasma and dialysate. Calculations revealed that phenobarbital was almost freely dialyzed.Correct dosing of drugs in patients on renal replacement therapy may need a multidisciplinary approach and guidance by therapeutic drug monitoring.

    Epilepsy is a brain disorder that affects both children and adults. From the 1920s the ketogenic diet has gained prestige as another treatment option for patients with refractory epilepsy. A summary of the evidence will be made through a systematic review of randomized clinical trials that have compared a single ketogenic diet with other diet for the management of these patients. To determine the effectiveness of the ketogenic diet in reducing episodes of seizures in patients with refractory epilepsy. The search strategy included randomized controlled trials and controlled clinical trials. Databases used were Medline, LILACS, Central and CINAHL. Six articles that met our elegibility criteria. There is limited evidence that the ketogenic diet compared to the medium-chain triglyceride diet is more effective in reducing the frequency of seizures. There is also moderate evidence that classical ketogenic diet compared to the gradual diet (2.5:1 and 3:1) is more effective in reducing seizures. There is moderate evidence that classical ketogenic diet compared to Atkins diet is more effective in reducing the frequency of seizure. The decision to apply this type of diet should also be based on costs, preferences and safety of treatment. It should also take into account the likelihood that studies have indexing problems have been left out of the review.

    Using several concentrations of eight anticonvulsant drugs in clinical use (carbamazepine, clonazepam, phenytoin, phenobarbital, ethosuximide, primidone, sodium valproate, and D,L-γ-vinyl GABA), we studied their abilities in vitro to displace ( 35 S)t-butylbicyclophosphorothionate ( 35 S-TBPS) from its binding site in a homogenate of rat brain. Thereafter ethosuximide (150 mg/kg), phenobarbital (30 mg/kg), clonazepam (0.3 mg/kg), or phenytoin (100 mg/kg) was injected intraperitoneally into rats for 16-20 days; and the effect of drug administration on 35 S-TBPS binding was studied in the cortex and hippocampus ex vivo. Phenobarbital (100 μM, P 35 S-TBPS binding in vitro by 10-16%. After drug administration of phenobarbital (concentration in plasma 168 μM), the number of binding sites decreased and the binding affinity (p 35 S-TBPS binding in vitro at the concentration analogous to therapeutic plasma levels or ex vivo at the dose used. These results suggest that the use of phenobarbital may modulate the TBPS binding site, but the role of the present findings in the anticonvulsant action of phenobarbital needs to be further studied.

    Full Text Available Background: The early and late benign occipital epilepsies of childhood (BOEC are described as two discrete electro-clinical syndromes, eponymously known as Panayiotopoulos and Gastaut syndromes. The purpose of this study was to identify predictors of failure to respond to the initial antiepileptic drug (AED. Materials and Methods: A total of 42 children with BOEC were enrolled. Predictive factors were analyzed by survival methods. Results: Among the 42, 25 patients (59.5% were boys and 17 (40.5% were girls and the mean age at the seizure onset was 7.46 ± 2.65 years (4-14 years. Of the 42 patients, 34 (81.0% were treated relatively successfully with the first AED treatment, and 8 (19.0% were not responded initial AED treatment. There was no correlation between response to initial AED treatment and sex, consanguinity, epilepsy history of family, age of seizure onset, frequency of seizures, history of status epilepticus, duration of starting first treatment, findings on electroencephalogram. However, history of febrile seizure and type of BOEC were significantly associated with failure risk. Conclusions: Factors predicting failure to respond to the AED were history of febrile seizure and type of BOEC in children with BOEC.

    Many drugs with unknown safety profiles are administered to pregnant women, placing their offspring at risk. I assessed whether behavioral outcomes for children exposed during gestation to antidepressants, anxiolytics, anti-seizure, analgesic, anti-nausea and sedative medications can be predicted by more extensive animal studies than are part of the FDA approval process. Human plus rodent data were available for only 8 of 33 CNS-active drugs examined. Similar behavioral and cognitive deficits, including autism and ADHD emerged in human offspring and in animal models of these disorders after exposure to fluoxetine, valproic acid, carbamazepine, phenytoin, phenobarbital and acetaminophen. Rodent data helpful in identifying and predicting adverse effects of prenatal drug exposure in children were first generated many years after drugs were FDA-approved and administered to pregnant women. I recommend that enhanced behavioral testing of rodent offspring exposed to drugs prenatally should begin during preclinical drug evaluation and continue during Phase I clinical trials, with findings communicated to physicians and patients in drug labels.

    Research suggests an increased risk for cognitive impairment in childhood epilepsy with memory being one area of cognition most likely to be affected. Understanding the prevalence and predictors of memory difficulties may help improve awareness of the difficulties and allow efficacious supports to be put in place. A systematic review was carried out using the search terms 'memory', 'children' and 'epilepsy' in the database PUBMED. Eighty-eight studies met inclusion criteria. The review focuses on comparisons of memory scores of children with epilepsy and controls, and comparison of memory scores of children with epilepsy to normative scores. Predictors of memory impairment and the effect of surgery on memory functioning are also reviewed. The majority (78%) of studies reviewed revealed that children with epilepsy scored lower than controls and normative scores on measures of memory. Post-surgery, memory scores were reported to improve in 50% of studies. Predictors of memory impairment included a greater number of AEDs used, younger age of onset, increased seizure frequency and longer duration of epilepsy. Children with epilepsy have a high frequency of memory impairments. However, the exact prevalence of difficulties is not clear due to the lack of population-based data. Most studies have not controlled for IQ and thus it is unclear if difficulties are always related to global cognitive difficulties. There is need for future population-based studies and studies focussing on the neurobiology of memory problems in children with epilepsy. Copyright © 2014 British Epilepsy Association.

    The International League Against Epilepsy (ILAE) Subcommittee for Pediatric Neuroimaging examined the usefulness of, and indications for, neuroimaging in the evaluation of children with newly diagnosed epilepsy. The retrospective and prospective published series with n ≥ 30 utilizing computed tomography (CT) and magnetic resonance imaging (MRI) (1.5 T) that evaluated children with new-onset seizure(s) were reviewed. Nearly 50% of individual imaging studies in children with localization-related new-onset seizure(s) were reported to be abnormal; 15-20% of imaging studies provided useful information on etiology or and seizure focus, and 2-4% provided information that potentially altered immediate medical management. A significant imaging abnormality in the absence of a history of a localization-related seizure, abnormal neurologic examination, or focal electro-encephalography (EEG) is rare. Imaging studies in childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, and benign childhood epilepsy with centro-temporal spikes (BECTS) do not identify significant structural abnormalities. Imaging provides important contributions to establishing etiology, providing prognostic information, and directing treatment in children with recently diagnosed epilepsy. Imaging is recommended when localization-related epilepsy is known or suspected, when the epilepsy classification is in doubt, or when an epilepsy syndrome with remote symptomatic cause is suspected. When available, MRI is preferred to CT because of its superior resolution, versatility, and lack of radiation. (authors)

    The relationship between parent health literacy and adherence to treatment in children with epilepsy has not been fully explored. The purpose of this study was to determine whether parent health literacy and other variables predicted factors associated with adherence, such as missed medication doses, missed medical appointments, and seizure frequency, in children with epilepsy between 1 and 12 years old. It was hypothesized that parents with adequate parent health literacy would report fewer missed doses, missed appointments, and seizure occurrences. Using a nonexperimental, cross-sectional study design, interviews were conducted with 146 parents and guardians of children with epilepsy who resided in rural communities. Univariate analyses, including ANOVA, and multiple linear regressions were conducted. Results indicated that parent health literacy was the strongest predictor of two of the adherence-related factors. Higher health literacy scores were associated with fewer missed medication doses and seizure occurrences. However, health literacy was not associated with missed medical appointments. Among other study variables, higher household income was also predictive of fewer missed doses. The study findings suggest that inadequate health literacy among parents may serve as an independent risk factor for adherence-related outcomes among children with epilepsy. Further research, as well as effective, targeted parent health literacy strategies used to improve epilepsy management and care in children, is recommended. Copyright © 2015 Elsevier Inc.

    The objective of this study was to identify two-year trajectories of epilepsy-specific health-related quality of life (HRQOL) among children newly diagnosed with epilepsy and to evaluate the predictive value of a comprehensive set of medical, psychosocial, and family factors. Ninety-four children with epilepsy (8.14 ± 2.37 years of age and 63% male) and their caregivers participated in this study. Caregivers completed the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE) and measures of psychological and family functioning at one month postdiagnosis. The QOLCE was also given at eight additional time points during the subsequent two years as a part of a large observational study in children with epilepsy. Adherence data were collected via MEMS TrackCaps, and medical information was collected through chart review. Unique trajectories were identified for the overall QOLCE scale, as well as the subscales. Most trajectory models for the QOLCE subscales contained at least one at-risk trajectory for children, indicating that there is a subgroup of children experiencing poor long-term HRQOL. Health-related quality-of-life trajectories remained predominantly stable during the two-year period following treatment initiation. The number of AEDs, internalizing problems, and externalizing problems emerged as the most consistent predictors across the HRQOL domains. Medical and psychosocial interventions, such as cognitive-behavioral strategies, should target modifiable factors (e.g., internalizing symptoms, externalizing symptoms, number of AEDs trialed) shortly after diagnosis to improve HRQOL for children with epilepsy over the course of their disease.

    Pharmacogenetics (PGX) is the study of how genetic variants influence individual responses to drugs. Although numerous candidate gene studies in epilepsy PGX have been published, to date only two validated associations exist: the association of the *2 and *3 alleles of CYP2C9 with phenytoin metabolism and the association of HLA-B*1502 with serious hypersensitivity reactions to carbamazepine. The advent of novel technologies such as genomewide association studies and next generation sequencing will likely lead to the identification of additional genetic biomarkers. The potential benefits of epilepsy PGX are multiple: epilepsy treatment in individual patients would become more rationalized, clinical trials could be stratified according to patients' genetic profiles and novel therapeutic pathways may be uncovered. Ultimately, it is hoped that PGX will improve the quality of life for people suffering from epilepsy worldwide. © 2013 médecine/sciences – Inserm / SRMS.

  11. Non-pharmacologic Therapeutic Alternatives for Children with Pharmacoresistant Epilepsy: Vagus Nerve Stimulation and Ketogenic Diet

    Directory of Open Access Journals (Sweden)

    Sibel K Velioğlu

    2014-06-01

    Full Text Available Approximately 20%-30% of individuals who develop epilepsy will develop medically refractory epilepsy. For this population, ‘‘alternative’’ or nonpharmacologic treatments such as vagus nerve stimulation (VNS and ketogenic diet (KD can be highly efficacious and should be seriously considered. Children and young people with medically-resistant epilepsy and poor candidates for epilepsy surgery may be referred to a tertiary paediatric epilepsy specialist for consideration of introducing VNS or KD. Information on the availability of VNS and KD in children is limited yet, due to the lack of suitably designed clinical studies in this population. VNS, is well-tolerated and effective as add-on therapy for refractory seizures in children. There has been no indication of reduction of effectiveness in long-term, open studies. Complications associated with implantation includes infection at the incision site, rib fractures and transient paralysis of the left vocal cord. Special caution is advised for children with pre-existing sleep apnea, cardiac conduction disorders, and asthma. Decreased seizure severity and recovery time, abolition of daytime drop attacks, and reduced hospitalization due to SE have improved patients’ quality of life. KD, with a nonfat-to-fat ratio of 1: 4 is a nonpharmacologic treatment for children with intractable epilepsy. Recent reports suggest that the benefit of KD is equivalent to any of the new anticonvulsant medications. The KD is difficult to maintain and has common side effects as constipation, acidosis, hypercholesterolemia, kidney stones, and hunger. It seems possible to design a therapy that is less rigorous and intrusive than the current KD, and promising alternative dietary approaches such as the Atkins and Low-glycemic-index (LGI diet are emerging.

    Stigma has been related to epilepsy since ancient times. Despite the importance of this issue, only a few interventions focusing on the reduction of epilepsy-related stigma may be found in the literature. Thus, the aim of this study is to evaluate the effectiveness of two interventions focused on the reduction of epilepsy-related stigma in children aged 9-11years. The first group of children involved in the study (n 1 =89) completed the 23-item Czech version of the SSE (Stigma Scale of Epilepsy) questionnaire and an 11-item multiple-choice knowledge test, then watched a video and completed the same questionnaire and test immediately after the intervention. The same procedure was used for the second group (n 2 =93) where a story was read by an instructor. Both groups were retested 6months later using the same methods. Both interventions resulted in long-term decrease of epilepsy-related stigma - the average value on SSE decreased from 55.15 points at baseline testing to 43.28 points in the 6-month follow-up for the case of the video (pinterventions were significant and effective ways to reduce epilepsy-related stigma in the given age group.

    To compare the efficacy of clonidine versus phenobarbital in reducing morphine sulfate treatment days for neonatal abstinence syndrome (NAS). Prospective, non-blinded, block randomized trial at a single level III NICU (Neonatal Intensive Care Unit). Eligible infants were treated with a combination of medications as per protocol. Primary outcome was treatment days with morphine sulfate. Secondary outcomes were the mean total morphine sulfate dose, outpatient phenobarbital days, adverse events and treatment failures. A total of 82 infants were eligible, of which 68 were randomized with 34 infants in each study group. Adjusting for covariates phenobarbital as compared with clonidine had shorter morphine sulfate treatment days (-4.6, 95% confidence interval (CI): -0.3, -8.9; P=0.037) with no difference in average morphine sulfate total dose (1.1 mg kg(-1), 95% CI: -0.1, 2.4; P=0.069). Post-discharge phenobarbital was continued for an average of 3.8 months (range 1 to 8 months). No other significant differences were noted. Phenobarbital as adjunct had clinically nonsignificant shorter inpatient but significant overall longer therapy time as compared with clonidine.

    After incidentally observing a patient in whom abnormal uptake of gallium-67 citrate appeared to be explained by treatment with phenytoin, we have conducted a prospective study. Of sixteen persons with a seizure disorder treated with phenytoin, five (31 percent) had abnormal uptake of radiogallium either in the mediastinum, pulmonary hilum or both. Of nineteen historical control patients only one had such abnormal uptake. Phenytoin may thus cause the false-positive uptake of radiogallium in lymph nodes; this finding may also prove to have nosological importance in identifying patients at particular risk of the side-effects of this drug

    The objective of this observational study was to evaluate the efficacy of medical cannabis for the treatment of refractory epilepsy. Fifty-seven patients (age 1-20 years) with epilepsy of various etiologies were treated with Cannabis oil extract (CBD/THC ratio of 20:1) for at least 3 months (Median follow up time-18 months). Forty-Six Patients were included in the efficacy analysis. Average CBD dose was11.4 mg/kg/d. Twenty-six patients (56%) had ≤50% reduction in mean monthly seizure frequency. There was no statistically significant difference in response rate among various epilepsy etiologies, and cannabis strain used. Younger age at treatment onset (CBD dose (>11 mg/kg/d) were associated with better response to treatment. Adverse reactions were reported in 46% of patients and were the main reason for treatment cessation. Our results suggest that adding CBD-enriched cannabis extract to the treatment regimen of patients with refractory epilepsy may result in a significant reduction in seizure frequency according to parental reports. Randomized controlled trials are necessary to assess its true efficacy. Copyright © 2018 Elsevier B.V. All rights reserved.

    To evaluate the efficacy and safety of mega-dose phenobarbital (MDPB; enteral or parenteral phenobarbital >10 mg/kg/day) for treating super-refractory status epilepticus (SRSE; continuous or recurrent status epilepticus for ≥24 hours after the onset of continuous anaesthetic treatment) in adult patients. Adult patients with SRSE who were treated with MDPB in our institution from March 2005 to September 2014 were reviewed. We collected data on basic demographics, clinical features, functional status, anticonvulsant treatment, and possible adverse events. SRSE outcome was divided into six categories: successful therapy, initial failure, breakthrough seizures, withdrawal seizures, intolerable side effects, and death during treatment. Ten adult patients with SRSE received MDPB. Median age at seizure onset was 38 years (range: 18-59), and half were male. All patients had no history of seizures and had symptoms suggestive of viral encephalitis. Median duration of status epilepticus was 17.5 days (range: 6-60) and anaesthetics were used for a median of 14.0 days (range: 2-54) before MDPB. Successful control of SRSE was achieved in half of the patients, however, only one of ten patients was able to fully recover at discharge. Median duration of the MDPB was 45.5 days and the maximum serum phenobarbital level reached a median of 151.5 μg/ml. Patients with successful MDPB therapy had normal brain imaging (80% vs. 0%; p=0.048) and better functional outcome at discharge and after three months of follow-up. Infection was the most critical complication, along with cardiorespiratory depression. MDPB is a therapeutic option for control of SRSE when other choices are exhausted.

    Marijuana appears to have anti-epileptic effects in animals. It is not currently known if it is effective in patients with epilepsy. Some states in the United States of America have explicitly approved its use for epilepsy. To assess the efficacy and safety of cannabinoids when used as monotherapy or add-on treatment for people with epilepsy. We searched the Cochrane Epilepsy Group Specialized Register (9 September 2013), Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2013, Issue 8), MEDLINE (Ovid) (9 September 2013), ISI Web of Knowledge (9 September 2013), CINAHL (EBSCOhost) (9 September 2013), and ClinicalTrials.gov (9 September 2013). In addition, we included studies we personally knew about that were not found by the searches, as well as searched the references in the identified studies. Randomized controlled trials (RCTs) whether blinded or not. Two authors independently selected trials for inclusion and extracted the data. The primary outcome investigated was seizure freedom at one year or more, or three times the longest interseizure interval. Secondary outcomes included responder rate at six months or more, objective quality of life data, and adverse events. We found four randomized trial reports that included a total of 48 patients, each of which used cannabidiol as the treatment agent. One report was an abstract and another was a letter to the editor. Anti-epileptic drugs were continued in all studies. Details of randomisation were not included in any study report. There was no investigation of whether the control and treatment participant groups were the same or different. All the reports were low quality.The four reports only answered the secondary outcome about adverse effects. None of the patients in the treatment groups suffered adverse effects. No reliable conclusions can be drawn at present regarding the efficacy of cannabinoids as a treatment for epilepsy. The dose of 200 to 300 mg daily of cannabidiol was

    Over last fifty years, intravenous (iv) phenytoin (PHT) loading dose has been the treatment of choice for patients with benzodiazepine-resistant convulsive status epilepticus and several guidelines recommended this treatment regimen with simultaneous iv diazepam. Clinical studies have never shown a better efficacy of PHT over other antiepileptic drugs. In addition, iv PHT loading dose is a complex and time-consuming procedure which may expose patients to several risks, such as local cutaneous reactions (purple glove syndrome), severe hypotension and cardiac arrhythmias up to ventricular fibrillation and death, and increased risk of severe allergic reactions. A further disadvantage of PHT is that it is a strong enzymatic inducer and it may make ineffective several drugs that need to be used simultaneously with antiepileptic treatment. In patients with a benzodiazepine-resistant status epilepticus, we suggest iv administration of levetiracetam as soon as possible. If levetiracetam would be ineffective, a further antiepileptic drug among those currently available for iv use (valproate, lacosamide, or phenytoin) can be added before starting third line treatment. © 2018 John Wiley & Sons A/S.

    OBJECTIVE Although epilepsy surgery is an effective treatment option, at least 20%-40% of patients can continue to experience uncontrolled seizures resulting from incomplete resection of the lesion, epileptogenic zone, or secondary epileptogenesis. Reoperation could eliminate or improve seizures. Authors of this study evaluated outcomes following reoperation in a pediatric population. METHODS A retrospective single-center analysis of all patients who had undergone resective epilepsy surgery in the period from 2001 to 2013 was performed. After excluding children who had repeat hemispherotomy, there were 24 children who had undergone a second surgery and 2 children who had undergone a third surgery. All patients underwent MRI and video electroencephalography (VEEG) and 21 underwent magnetoencephalography (MEG) prior to reoperation. RESULTS The mean age at the first and second surgery was 7.66 (SD 4.11) and 10.67 (SD 4.02) years, respectively. The time between operations ranged from 0.03 to 9 years. At reoperation, 8 patients underwent extended cortical resection; 8, lobectomy; 5, lesionectomy; and 3, functional hemispherotomy. One year after reoperation, 58% of the children were completely seizure free (International League Against Epilepsy [ILAE] Class 1) and 75% had a reduction in seizures (ILAE Classes 1-4). Patients with MEG clustered dipoles were more likely to be seizure free than to have persistent seizures (71% vs 40%, p = 0.08). CONCLUSIONS Reoperation in children with recurrent seizures after the first epilepsy surgery could result in favorable seizure outcomes. Those with residual lesion after the first surgery should undergo complete resection of the lesion to improve seizure outcome. In addition to MRI and VEEG, MEG should be considered as part of the reevaluation prior to reoperation.

    Objectives Compare the safety of antiepileptic drugs (AEDs) on neurodevelopment of infants/children exposed in utero or during breast feeding. Design and setting Systematic review and Bayesian random-effects network meta-analysis (NMA). MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials were searched until 27 April 2017. Screening, data abstraction and quality appraisal were completed in duplicate by independent reviewers. Participants 29 cohort studies including 5100 infants/children. Interventions Monotherapy and polytherapy AEDs including first-generation (carbamazepine, clobazam, clonazepam, ethosuximide, phenobarbital, phenytoin, primidone, valproate) and newer-generation (gabapentin, lamotrigine, levetiracetam, oxcarbazepine, topiramate, vigabatrin) AEDs. Epileptic women who did not receive AEDs during pregnancy or breast feeding served as the control group. Primary and secondary outcome measures Cognitive developmental delay and autism/dyspraxia were primary outcomes. Attention-deficit hyperactivity disorder, language delay, neonatal seizures, psychomotor developmental delay and social impairment were secondary outcomes. Results The NMA on cognitive developmental delay (11 cohort studies, 933 children, 18 treatments) suggested that among all AEDs only valproate was statistically significantly associated with more children experiencing cognitive developmental delay compared with control (OR=7.40, 95% credible interval (CrI) 3.00 to 18.46). The NMA on autism (5 cohort studies, 2551 children, 12 treatments) suggested that oxcarbazepine (OR 13.51, CrI 1.28 to 221.40), valproate (OR 17.29, 95% CrI 2.40 to 217.60), lamotrigine (OR 8.88, CrI 1.28 to 112.00) and lamotrigine+valproate (OR 132.70, CrI 7.41 to 3851.00) were associated with significantly greater odds of developing autism compared with control. The NMA on psychomotor developmental delay (11 cohort studies, 1145 children, 18 treatments) found that valproate (OR 4.16, CrI 2.04 to 8

    Purpose To establish the efficacy and safety of methylphenidate (MPH) treatment for attention deficit hyperactivity disorder (ADHD) in a group of children and young people with learning disability and severe epilepsy. Methods This retrospective study systematically reviewed the case notes of all patients treated with methylphenidate (MPH) for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) ADHD at a specialist epilepsy center between 1998 and 2005. Treatment efficacy was ascertained using clinical global impressions (CGI) scores, and safety was indexed by instances of >25% increase in monthly seizure count within 3 months of starting MPH. Key Findings Eighteen (18) patients were identified with refractory epilepsies (14 generalized, 4 focal), IQ <70, and ADHD. Male patients predominated (13:5) and ADHD was diagnosed at a median age of 11.5 years (range 6–18 years). With use of a combination of a behavioral management program and MPH 0.3–1 mg/kg/day, ADHD symptoms improved in 61% of patients (11/18; type A intraclass correlation coefficient of CGI 0.85, 95% confidence interval [CI] 0.69–0.94). Daily MPH dose, epilepsy variables, and psychiatric comorbidity did not relate to treatment response across the sample. MPH adverse effects led to treatment cessation in three patients (dysphoria in two, anxiety in one). There was no statistical evidence for a deterioration of seizure control in this group with the use of MPH. Significance Methylphenidate with behavioral management was associated with benefit in the management of ADHD in more than half of a group of children with severe epilepsy and additional cognitive impairments. Eighteen percent had significant side effects but no attributable increase in seizures. Methylphenidate is useful in this group and is likely to be under employed. PMID:24304474

Regarding seizure-frequency reduction ≥50% from baseline, levetiracetam also seemed equivalent to other AEDs (RR 1.08, 95% CI 1.01–1.16; P=0.35. In spite of patients treated with levetiracetam having a lower incidence of side effects compared with patients treated with other AEDs (RR 0.90, 95% CI 0.77–1.06, the difference between them was minute and not statistically significant (P=0.22.Conclusion: Based on this meta-analysis, it seemed that levetiracetam had comparable effects concerning efficacy, tolerability, and adverse events. Nevertheless, 13 studies were insufficient to draw a conclusion that levetiracetam is effective as mono- and adjunctive therapy for all types of epilepsy syndromes and seizures. Larger-sample and more well-designed trials are needed to justify the widespread use of levetiracetam in

    Recognizing the importance of patient-reported outcomes, this longitudinal, prospective study examined: Changes in health-related quality of life (HRQOL) over seven months following antiepileptic drug (AED) initiation and the relationship of seizures, AED side-effects, and AED type to HRQOL. Parents of 124 children with newly diagnosed epilepsy completed measures of HRQOL and side-effects at each clinic visit. Treatment information was also collected. HRQOL remained stable over time; however, seizures and AED side-effects significantly affected multiple HRQOL domains. Higher seizure activity was associated with decreased Physical HRQOL. Side-effects were negatively associated with all HRQOL domains. Children taking carbamazepine who experienced higher side-effects early in therapy demonstrated declining emotional functioning compared to children experiencing no/some side-effects. AED side-effects, AED type, and seizure frequency were associated with longitudinal HRQOL in children with newly-diagnosed epilepsy. Routine assessment of AED side-effects and HRQOL may be useful for clinical decision making.

    Partial epilepsy is a very important problem of epileptology in childhood including clinical and therapeutic aspect especially surgery treatment. The aim of this study is to assess clinical value of neuroimagine techniques (structural MRI, MRI angiography) in partial epilepsy diagnostics in children. The relation between results of examinations with these methods and congenital and acquired risk factors related to partial epilepsy, age of its onset and clinical assessment of patients was analyzed. The study group consisted of 140 children with partial epilepsy hospitalized between 1998 and 2004 in Department of Pediatric Neurology, Collegium Medicum Jagiellonian University, Krakow. The group included 70 girls and 70 boys, the age ranged from 2 months to 17 years. In study group statistical analysis included different factors as which can be related with results of neuroimaging as age, load of pregnancy and birth period, familiar epilepsy, patient's risk factors for appearance of epilepsy, acquired risk factors of epilepsy, results of neurological examination, type of epilepsy, status epilepticus, and signs according epileptic attacks which can be related with neuroimaging results. The primary method of neuroimagine in all patients was structural MRI, in 16 cases Magnetic Resonance Angiography (MRA). The parametric tests (t-student), nonparametric Mann-Whitney's test were used in statistical analysis. The bilateral Fisher test was used to check rate in groups. There was assessed sensitivity, specificity, positive predictive value, negative predictive value; the 95% confidence interval was calculated for these parameters. Abnormalities in neurological examination in children with partial epilepsy were strongly correlated with MRI findings. The structural changes in MRI were found in younger children, whose course of epilepsy was longer than children without MRI changes. Changes in hippocampus ere the most common in children with partial epilepsy with abnormalities in

    2013-01-01

    Background In human medicine, adverse outcomes associated with switching between bioequivalent brand name and generic antiepileptic drug products is a subject of concern among clinicians. In veterinary medicine, epilepsy in dogs is usually treated with phenobarbital, either with the standard brand name formulation Luminal® or the veterinary products Luminal® vet and the generic formulation Phenoleptil®. Luminal® and Luminal® vet are identical 100 mg tablet formulations, while Phenoleptil® is available in the form of 12.5 and 50 mg tablets. Following approval of Phenoleptil® for treatment of canine epilepsy, it was repeatedly reported by clinicians and dog owners that switching from Luminal® (human tablets) to Phenoleptil® in epileptic dogs, which were controlled by treatment with Luminal®, induced recurrence of seizures. In the present study, we compared bioavailability of phenobarbital after single dose administration of Luminal® vet vs. Phenoleptil® with a crossover design in 8 healthy Beagle dogs. Both drugs were administered at a dose of 100 mg/dog, resulting in 8 mg/kg phenobarbital on average. Results Peak plasma concentrations (Cmax) following Luminal® vet vs. Phenoleptil® were about the same in most dogs (10.9 ± 0.92 vs. 10.5 ± 0.77 μg/ml), and only one dog showed noticeable lower concentrations after Phenoleptil® vs. Luminal® vet. Elimination half-life was about 50 h (50.3 ± 3.1 vs. 52.9 ± 2.8 h) without differences between the formulations. The relative bioavailability of the two products (Phenoleptil® vs. Luminal® vet.) was 0.98 ± 0.031, indicating that both formulations resulted in about the same bioavailability. Conclusions Overall, the two formulations did not differ significantly with respect to pharmacokinetic parameters when mean group parameters were compared. Thus, the reasons for the anecdotal reports, if true, that switching from the brand to the generic formulation of phenobarbital may lead to

    Epilepsy is a serious neurologic disorder worldwide which affects about 1% of the population (ca. 50 million people), the highest prevalence occurring in both children and elderly. Apart from idiopathic forms, etiology of the disease involves multiple brain risk factors - the most frequent being cerebrovascular diseases, tumours and traumatic injuries. Several treatment options exist, including, for instance, pharmacotherapy, vagal nerve stimulation or epilepsy surgery. In spite of treatment, about 30% of patients with epilepsy still have seizures and become drug-refractory. This is why other treatment options may be recommended, and ketogenic diet seems a last-chance method, especially in children and adolescents with epilepsy. The diet contains high amounts of fat and low carbohydrates with vitamin supplementation. The elevated concentrations of ketones induced by the diet may result in inhibition of the synaptic activity of glutamate, the mammalian target of the rapamycin pathway, and activation of adenosine triphosphate-sensitive potassium channels. One of the main ketones is acetone, shown to increase the seizure threshold and potentiate the anticonvulsant activity of some antiepileptic drugs. The clinical effectiveness of the ketogenic diet has been confirmed in a number of clinical trials carried out mainly on children. A wider use of the ketogenic diet may be limited by the number of early adverse effects (gastrointestinal distress, acidosis, hypoglycaemia, dehydration and lethargy), and late adverse effects (hyperuricaemia, hyperlipidaemia, kidney stones, easy bruising, and decreases in height and weight). Recently, data are available on the negative impact of the ketogenic diet on the qualitative characteristics of lipoprotein subfractions which points to the atherogenic fenotype as a new side-effect. In conclusion, future research directed to the proper identification of patients (in terms of age, epilepsy type and duration, recommended antiepileptic

    Epilepsy has several comorbidities and associated stigma. Stigma associated with epilepsy is well known and prevalent worldwide. Surgical treatment is an established treatment for drug refractory epilepsy. Following surgery in children, it is possible that the stigma may reduce, but such an effect has not been studied earlier. Analysis of prospectively collected data was performed for pediatric patients at a single tertiary center for treating epilepsy. Child stigma scale, as described by Austin et al., was used to evaluate stigma both pre- and postoperatively. Analysis was done using Paired t test. In this study, following surgery, there was significant reduction of stigma (Pstigma despite having good seizure outcome. Surgery in drug-resistant epilepsy helps in reducing stigma. Seizure reduction is probably not the only factor responsible for a change in stigma outcome. Copyright © 2018 Elsevier Inc. All rights reserved.

    In 1978, a pilot study began of 29 patients with advanced tumors of the head and neck. The study showed an initial peripheral neuropathy rate of 55%, despite a dose limitation of 12 g/m 2 of misonidazole. Tumor response at 9 months was most encouraging. We are now able to examine tumor response and persistence of neuropathy in these patients 2 1/2 years after radical radiotherapy. The results are comparable with those obtained with hyperbaric oxygen in a clinical trial at this center during the 1970's. Neuropathy was a serious side effect but the drug phenytoin has been shown to shorten the half-life of misonidazole. We have examined the effect of phenytoin on the pharmacokinetics of misonidazole in 13 patients who received radical radiotherapy for advanced head and neck tumors or oesophageal tumors. Misonidazole was given in multiple doses, i.e. daily or weekly as it would be used in conventional therapy. Phenytoin was given either daily throughout treatment, or it was withdrawn during treatment. There were dramatic changes in the half-life of misonidazole, but the concentration at the time of irradiation was little affected. The significant changes in the half-life of misonidazole and the increased concentration of the metabolite desmethylmisonidazole are discussed

    Full Text Available The occurrence of epileptic seizures in the presence of hepatic disease is not uncommon in clinical practice. Selecting an appropriate AED for patients affected by liver failure who have new-onset epileptic seizures can be challenging. We describe a 64-year-old man affected by liver cirrhosis. The patient developed partial epilepsy with secondary generalization because of an intracerebral hemorrhage in the left parieto-occipital regions. After the neurosurgery procedure, seizures reappeared and were initially managed with levetiracetam. After one month, the patient experienced clusters of seizures while on stable treatment with levetiracetam. Pregabalin as add-on was not tolerated; therefore, he received a low dose of phenobarbital as add-on treatment. The patient developed hepatic encephalopathy. Phenobarbital was immediately stopped, and oral lacosamide was added. A rapid recovery of encephalopathy with a 6-month seizure freedom was obtained. The patient died 6 months later because of progressive impairment of liver function. Lacosamide may represent an alternative to other AEDs in patients with liver failure; however, further prospective evaluation of its efficacy and safety in this clinical setting is needed.

    Mozart's Sonata for Two Pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart Effect. Our previous work revealed that epileptiform discharges in children with epilepsy decrease during and right after listening to Mozart K.448. However, the duration of the effect was not studied. In the study described here, we evaluated the long-term effect of Mozart K.448 on epileptiform discharges in children with epilepsy. Eighteen children with epilepsy whose seizures were clinically well controlled with antiepileptic drugs were included. For each child, EEGs had revealed persistent epileptiform discharges for at least 6 months. These patients listened to Mozart K.448 for 8 minutes once a day before bedtime for 6 months. Epileptiform discharges were recorded and compared before and after 1, 2, and 6 months of listening to Mozart K.448. All of the children remained on the same antiepileptic drug over the 6 months. Relationships between number of epileptiform discharges and foci of discharges, intelligence, epilepsy etiology, age, and gender were analyzed. Epileptiform discharges significantly decreased by 53.2±47.4, 64.4±47.1, and 71.6±45.8%, respectively, after listening to Mozart K.448 for 1, 2, and 6 months. All patients except those with occipital discharges showed a significant decrease in epileptiform discharges. Patients with normal intelligence and idiopathic epilepsy had greater decreases than those with mental retardation and symptomatic epilepsy. Age and gender did not affect the results. We conclude that long-term listening to Mozart K.448 may be effective in decreasing epileptiform discharges in children with epilepsy in a chronologically progressive manner.

    Gamma knife radiosurgery (GKRS) for mesial temporal lobe epilepsy (MTLE) has been proposed as an alternative to surgical resection. We report serious adverse effects of the treatment after follow-up periods over 9 years in 11 patients treated with GKRS between 1997 and 2000. The target volume of the entorhinoamygdalohippocampectomy area was 4.8-17.1 ml. Marginal dose of 20-25 Gy to the 50% isodose was delivered. One patient was drowned after suffering seizure 7 months after GKRS. Two patients did not show any reduction in seizure frequency over 9 and 18 months. Both patients requested open surgery and became seizure-free postoperatively. Four of the other eight patients were classified as Engel's class I within 4 years after GKRS. One of the four patients experienced symptomatic radiation-induced cerebral edema transiently, one developed radiation necrosis and required surgery 5 years after GKRS, and one developed cognitive impairment with hemiparesis 10 years after GKRS. Magnetic resonance (MR) imaging showed a large cyst in the irradiated temporal lobe. This patient recovered fully after the cyst excision. Only one patient became seizure-free and antiepileptic drug-free without symptomatic radiation-induced complications. However, MR imaging revealed abnormal enhancement, cyst formation, and diffuse white matter change in the irradiated temporal lobe 9 years after GKRS. GKRS for MTLE causes adverse effects of delayed seizure remission and symptomatic radiation-induced complications. Therefore, GKRS cannot be considered as an ideal alternative to surgery for MTLE. Long-term follow-up studies including MR imaging with contrast medium are required for the patients even after successful control of seizures. (author)

    Status epilepticus is common in neonates and infants, and is associated with neuronal injury and adverse developmental outcomes. γ-Aminobutyric acidergic (GABAergic) drugs, the standard treatment for neonatal seizures, can have excitatory effects in the neonatal brain, which may worsen the seizures and their effects. Using a recently developed model of status epilepticus in postnatal day 7 rat pups that results in widespread neuronal injury, we found that the GABA A agonists phenobarbital and midazolam significantly increased status epilepticus-associated neuronal injury in various brain regions. Our results suggest that more research is needed into the possible deleterious effects of GABAergic drugs on neonatal seizures and on excitotoxic neuronal injury in the immature brain.

    Full Text Available Children with epilepsy have a high rate of mood and behavior problems yet few studies consider the emotional and behavioral impact of surgery. No study to date has been sufficiently powered to investigate effects of both side (left/right and site (temporal/frontal of surgery. One hundred patients (aged 6-16 and their families completed measures of depression, anxiety and behavioral function as part of neuropsychological evaluations before and after surgery for pharmacoresistant epilepsy. Among children who had left-sided surgeries (frontal=16; temporal=38, there were significant interactions between time (pre to postoperative neuropsychological assessment and resection site (frontal/temporal on Anhedonia, Social Anxiety, and Withdrawn/Depressed scales. Patients with frontal lobe epilepsy (FLE endorsed greater presurgical anhedonia and social anxiety than patients with temporal lobe epilepsy (TLE, with scores normalizing following surgery. While scores on the Withdrawn/Depressed scale were similar between groups before surgery, the FLE group showed greater symptom improvement after surgery. In children who underwent right-sided surgeries (FLE=20; TLE=26 main effects of time (patients in both groups improved and resection site (caregivers of FLE patients endorsed greater symptoms than those with TLE were observed primarily on behavior scales. Individual data revealed that a greater proportion of children with left FLE demonstrated clinically significant improvements in Anhedonia, Social Anxiety, and Aggressive Behavior than children with TLE. This is the first study to demonstrate differential effects of both side and site of surgery in children with epilepsy at group and individual levels. Results suggest that children with FLE have greater emotional and behavioral dysfunction before surgery, but show marked improvement after surgery. Overall, most children had good emotional and behavioral outcomes, with most scores remaining stable or improving.

    Few clinical studies have assessed the efficacy and safety of oxcarbazepine (OXC) oral suspension in Asian pediatric patients and particularly in infants. The aim of this study was to investigate and compare the efficacy, tolerability, and side effects of OXC oral suspension in Taiwanese infants and children with various types of epilepsy. A retrospective review of the efficacy, tolerability, and side effects of OXC oral suspension in a tertiary medical center in Taiwan was conducted and included children (1-9 years old) and infants (effects (30 vs. 21 %, p = 0.525) after OXC oral suspension treatment. The efficacy was significantly correlated with the epilepsy subtype (p effective and well tolerated in both infants and children with partial epilepsy in Taiwan. Treatment efficacy was related to epilepsy subtype and number of combined AEDs before OXC treatment. Monotherapy had an excellent therapeutic response in partial epilepsy but not in multifocal epilepsy.

    To characterize, among European and Han Chinese populations, the genetic predictors of maculopapular exanthema (MPE), a cutaneous adverse drug reaction common to antiepileptic drugs. We conducted a case-control genome-wide association study of autosomal genotypes, including Class I and II human leukocyte antigen (HLA) alleles, in 323 cases and 1,321 drug-tolerant controls from epilepsy cohorts of northern European and Han Chinese descent. Results from each cohort were meta-analyzed. We report an association between a rare variant in the complement factor H-related 4 ( CFHR4 ) gene and phenytoin-induced MPE in Europeans ( p = 4.5 × 10 -11 ; odds ratio [95% confidence interval] 7 [3.2-16]). This variant is in complete linkage disequilibrium with a missense variant (N1050Y) in the complement factor H ( CFH ) gene. In addition, our results reinforce the association between HLA-A*31:01 and carbamazepine hypersensitivity. We did not identify significant genetic associations with MPE among Han Chinese patients. The identification of genetic predictors of MPE in CFHR4 and CFH, members of the complement factor H-related protein family, suggest a new link between regulation of the complement system alternative pathway and phenytoin-induced hypersensitivity in European-ancestral patients.

    2011-01-01

    Full Text Available Nonpharmacological treatment of epilepsy includes surgery, vagal nerve stimulation, ketogenic diet, and other alternative/complementary therapies, e.g., yoga, Ayurveda, electroencephalography (EEG biofeedback technique, aerobic exercise, music therapy, transcranial magnetic stimulation, acupuncture, and herbal remedies (traditional Chinese medicine. Alternative therapies, despite the term, should not be considered as an alternative to antiepileptic medication; they complement accepted drug treatment. Alternative therapies like yoga, through techniques that relax the body and mind, reduce stress, improve seizure control, and also improve quality of life. Ketogenic diet is a safe and effective treatment for intractable epilepsies; it has been recommended since 1921. The diet induces ketosis, which may control seizures. The most successful treatment of epilepsy is with modern antiepileptic drugs, which can achieve control of seizures in 70-80% cases. Patients opt for alternative therapies because they may be dissatisfied with antiepileptic drugs due to their unpleasant side effects, the long duration of treatment, failure to achieve control of seizures, cultural beliefs and, in the case of women, because they wish to get pregnant Surgical treatment may lead to physical and psychological sequelae and is an option only for a minority of patients. This article presents supportive evidence from randomized controlled trials done to assess the benefit of non-pharmacological treatment.

  9. Similarities and differences in the meanings children and their parents attach to epilepsy medications.

    By exploring the meanings children and their parents attached to two household treatments for childhood epilepsy (antiepileptic drugs and emergency medications), this paper broadens our understanding of the ways in which children view their medications and how these views can impact on their adherence to treatment. The paper draws on data collected during 2013 and 2014 from 24 families across the UK that had a child with epilepsy aged 3-13 years. In-depth semi-structured interviews were conducted with the parents and 10 children participated in autodriven photo-elicitation interviews. Parents' and children's perceptions of medications were compared and contrasted and the findings show that although both parents and children viewed medications as an unpleasant necessity, parents' concerns centred on the perceived side effects of medications, whereas the children commented on the process of ingesting medications. Additionally, some of the children had to learn that their medications were a preventative measure, as they originally viewed them as a cure. Furthermore, among the children, it was found that treatment could be seen as either a positive or negative symbol of difference. Lastly, emergency medications were often viewed as a saviour, particularly by parents. Through this analysis, the study shows that the meanings children attached to medications were often linked to the form the medication took and that the way in which children perceived their medications had implications for their adherence; indeed, those who viewed their medications as an unpleasant necessity and those who initially saw their treatment as a cure were most likely to stop taking their medications. Consequently, this paper contributes to the current literature on the meanings individuals attach to treatments by providing the first detailed insight into children's views on epilepsy medications and by illustrating the similarities and differences in children's and parents' perspectives

    To investigate what proportion of a regional cohort of cooled infants with neonatal encephalopathy develop epilepsy (determined by the International League Against Epilepsy [ILAE] definition and the number of antiepileptic drugs [AEDs]) up to 8 years of age. From 2006-2013, 151 infants with perinatal asphyxia underwent 72 h cooling. Clinical and amplitude-integrated electroencepalography (aEEG) with single-channel EEG-verified neonatal seizures were treated with AEDs. Brain magnetic resonance imaging (MRI) was assessed using a 0-11 severity score. Postneonatal seizures, epilepsy rates, and AED treatments were documented. One hundred thirty-four survivors were assessed at 18-24 months; adverse outcome was defined as death or Bayley III composite Cognition/Language or Motor scores <85 and/or severe cerebral palsy or severely reduced vision/hearing. Epilepsy rates in 103 children age 4-8 years were also documented. aEEG confirmed seizures occurred precooling in 77 (57%) 151 of neonates; 48% had seizures during and/or after cooling and received AEDs. Only one infant was discharged on AEDs. At 18-24 months, one third of infants had an adverse outcome including 11% mortality. At 2 years, 8 (6%) infants had an epilepsy diagnosis (ILAE definition), of whom 3 (2%) received AEDs. Of the 103 4- to 8-year-olds, 14 (13%) had developed epilepsy, with 7 (7%) receiving AEDs. Infants/children on AEDs had higher MRI scores than those not on AEDs (median [interquartile range] 9 [8-11] vs. 2 [0-4]) and poorer outcomes. Nine (64%) of 14 children with epilepsy had cerebral palsy compared to 13 (11%) of 120 without epilepsy, and 10 (71%) of 14 children with epilepsy had adverse outcomes versus 23 (19%) of 120 survivors without epilepsy. The number of different AEDs given to control neonatal seizures, aEEG severity precooling, and MRI scores predicted childhood epilepsy. We report, in a regional cohort of infants cooled for perinatal asphyxia, 6% with epilepsy at 2 years (2% on AEDs

    Reliable change indices (RCIs) and standardized regression-based (SRB) change score norms permit evaluation of meaningful changes in test scores following treatment interventions, like epilepsy surgery, while accounting for test-retest reliability, practice effects, score fluctuations due to error, and relevant clinical and demographic factors. Although these methods are frequently used to assess cognitive change after epilepsy surgery in adults, they have not been widely applied to examine cognitive change in children with epilepsy. The goal of the current study was to develop RCIs and SRB change score norms for use in children with epilepsy. Sixty-three children with epilepsy (age range: 6-16; M=10.19, SD=2.58) underwent comprehensive neuropsychological evaluations at two time points an average of 12 months apart. Practice effect-adjusted RCIs and SRB change score norms were calculated for all cognitive measures in the battery. Practice effects were quite variable across the neuropsychological measures, with the greatest differences observed among older children, particularly on the Children's Memory Scale and Wisconsin Card Sorting Test. There was also notable variability in test-retest reliabilities across measures in the battery, with coefficients ranging from 0.14 to 0.92. Reliable change indices and SRB change score norms for use in assessing meaningful cognitive change in children following epilepsy surgery are provided for measures with reliability coefficients above 0.50. This is the first study to provide RCIs and SRB change score norms for a comprehensive neuropsychological battery based on a large sample of children with epilepsy. Tables to aid in evaluating cognitive changes in children who have undergone epilepsy surgery are provided for clinical use. An Excel sheet to perform all relevant calculations is also available to interested clinicians or researchers. Copyright © 2015 Elsevier Inc. All rights reserved.

    Objectives: The purpose of this study was to determine the prevalence of the adverse events of antiretroviral treatment, their impact on mortality and the change in regimens prescribed to children treated at Mildway Centre in Uganda. Method: A retrospective chart review was performed for children younger than 6 years, treated since the Mildway Centre was opened in 1999. In order to achieve a larger sample, the records of children treated from January 2000 to July 2005 were included in the study. A pre-tested data collection form was used to collate socio-demographic and clinical data of the patients. These included the documented adverse events, causes of death, stage of infection, duration of treatment, regimen prescribed, year of enrolment into the treatment program, as well as whether or not they were still alive. Descriptive statistics were used in the analysis of data. Results: Of the 179 children, the majority were males and had a median age of 4 years. The majority (58.8% of children had suffered from severe immune depression since they met the WHO clinical stage III and IV, 73.8% had a baseline CD4T of less than 15%. Four regimens were prescribed to the children. The most common was a regimen containing zidovudine, lamivudine, and nevirapine (34.6%, followed by a regimen containing stavudine, lamivudine, and nevirapine (27.9%. Eleven children (6.1% had their regimen changed, of which six (54.5% were due to adverse events. The prevalence of adverse events was 8%; of the 14 documented adverse events, the most common were severe anaemia (3, vomiting (3, and skin rashes (3. After 12 months on treatment, 8% of the patients had died. The most common causes of death were infectious diseases (28.6%, severe anaemia (21.4%, and severe dehydration (21.4%. Conclusion: The prevalence of adverse events was 8%; they were responsible for 54.5% of regimen changes and 21.4% of deaths in children treated at the study site. These findings suggest the need for incorporating

    Mozart's Sonata for two pianos in D major, K.448 (Mozart K.448), has been shown to improve mental function, leading to what is known as the Mozart effect. Our previous work revealed that epileptiform discharges in children with epilepsy decreased during and immediately after listening to Mozart K.448. In this study, we evaluated the long-term effects of Mozart K.448 on children with refractory epilepsy. Eleven children with refractory epilepsy were enrolled. All of the patients were diagnosed as having had refractory epilepsy for more than 1 year (range =1 year to 6 years 4 months, mean =3 years 11 months) and had been receiving at least two antiepileptic drugs (AED). During the study period, they listened to Mozart K.448 once a day before bedtime for 6 months. Seizure frequencies were recorded 6 months before they started listening to this music and monthly during the study period. All of the patients remained on the same AEDs during the 6-month study period. Frequencies of seizures were compared before and after listening to Mozart K.448. Eight of eleven patients were seizure free (N=2) or had very good responses (N=6) after 6 months of listening to Mozart K.448. The remaining three (27.3%) showed minimal or no effect (effectiveness Mozart K.448 should be further studied as a potential add-on therapy in the treatment of children with refractory epilepsy.

    In May 2015 the World Health Assembly (WHA) approved the Resolution on the Global Burden of Epilepsy. This report addresses how the Resolution can be leveraged to improve the care of children with epilepsy worldwide. Children with epilepsy have unique needs and face unique challenges from stigma at all levels of society. Children lack a voice to lobby for their own needs, including their right to have access to education. Effective leadership and governance should be enhanced through the support of stakeholders empowered to counsel, advise, and lobby for appropriate care. National health care plans should integrate primary and specialist care, and they need to be adapted to local specificities. Antiepileptic medicines should be widely accessible in appropriate, sustained, and affordable ways. Public awareness initiatives are needed to improve the inclusion of affected children in society and to reduce stigma. Cost-effective interventions are also needed to address preventable causes of epilepsy. Without greater investment in research, evidence-based interventions cannot be implemented. Through all of this, civil society must be engaged to ensure that the multivariate dimensions from the clinic to the community are addressed to fulfil the needs of children with epilepsy.

    Sleep problems are common in pediatric epilepsy and may influence seizure control, daytime functioning, and overall quality of life. Knowledge of factors contributing to sleep problems is likely to improve treatment. The aim of this study was to investigate associations between psychiatric comorbidity and parent-reported and self-reported sleep problems in a sample of children and adolescents with epilepsy. Participants were children and adolescents (N=94), aged 10-19years, with generalized or focal epilepsy who had been referred to a tertiary epilepsy treatment center in Norway. Participants underwent a thorough clinical assessment and 24h of EEG registration. Information on sleep problems was obtained from parents using the Children's Sleep Habit Questionnaire (CSHQ) and from self-reporting using the Sleep Self-Report (SSR) questionnaire. Psychiatric diagnoses were established using the semistructured psychiatric interview Schedule for Affective Disorders and Schizophrenia - Present and Lifetime Version (Kiddie-SADS-PL). Both the total and subdomain CSHQ and SSR scores were high in comparison with scores from population-based samples. Having one or more psychiatric disorder(s) was significantly associated with elevated scores on both the CSHQ and the SSR. With the exception of parent-reported parasomnias, associations between sleep problems and psychiatric disorders remained significant after adjusting for relevant epilepsy variables. Psychiatric comorbidity explained about one-third of the variance of the reported sleep problems in children and adolescents with epilepsy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Given the significant impact that psychosocial factors and epilepsy treatments can have on the health-related quality of life (HRQOL) of individuals with epilepsy and their families, there is great clinical interest in the role of psychological evaluation and treatments to improve HRQOL and comorbidities. Therefore, the International League Against Epilepsy (ILAE) charged the Psychology Task Force with the development of recommendations for clinical care based on evaluation of the evidence from their recent Cochrane review of psychological treatments in individuals with epilepsy. The literature search for a recent Cochrane review of randomized controlled trials investigating psychological treatments for individuals with epilepsy constitutes the key source of evidence for this article. To provide practical guidance to service providers, we provide ratings on study research designs based on (1) the American Academy of Neurology's Level of Evidence system and (2) the Grading of Recommendations, Assessment, Development, and Evaluation system. This paper is the culmination of an international collaboration process involving pediatric and adult psychologists, neurologists, psychiatrists, and neuropsychiatrists. The process and conclusions were reviewed and approved by the ILAE Executive Committee. The strongest evidence for psychological interventions was identified for the most common mental health problems, including depression, neurocognitive disturbances, and medication adherence. Psychological interventions targeting the enhancement of HRQOL and adherence and a decrease in comorbidity symptoms (anxiety, depression) should be incorporated into comprehensive epilepsy care. There is a range of psychological strategies (ie, cognitive behavioral therapy and mindfulness-based therapies) that show promise for improving the lives of persons with epilepsy, and clinical recommendations are provided to assist epilepsy health care providers in treating the comorbidities and

    A 68-year-old woman tried to commit suicide using phenobarbital, which was initially prescribed for her dog that suffered from seizures. At admission she was unconscious and ventilated. Five days of intensive care therapy did not improve her state of consciousness. Subsequent continuous veno-venous hemodialysis accelerated the elimination of phenobarbital compared to endogenous elimination by a factor of five. The patient survived without sequelae. Detailed history taking and well-timed indication for dialysis were crucial.

    Academic self-concept could significantly affect academic achievement and self-confidence in children with epilepsy. However, limited attention has been devoted to determining factors influencing academic self-concept of children with epilepsy. We aimed to analyze potentially significant variables (gender, frequency of seizures, duration of epilepsy, intellectual disability, learning disability and attention deficit hyperactivity disorder) in relation to academic self-concept in children with epilepsy and to additional domains of their quality of life. The study group consisted of 182 children and adolescents aged 9-14 years who completed the SPAS (Student's Perception of Ability Scale) questionnaire determining their academic self-concept and the modified Czech version of the CHEQOL-25 (Health-Related Quality of Life Measure for Children with Epilepsy) questionnaire evaluating their health-related quality of life. Using regression analysis, we identified learning disability as a key predictor for academic-self concept of children with epilepsy. While children with epilepsy and with no learning disability exhibited results comparable to children without epilepsy, participants with epilepsy and some learning disability scored significantly lower in almost all domains of academic self-concept. We moreover found that children with epilepsy and learning disability have significantly lower quality of life in intrapersonal and interpersonal domains. In contrast to children with epilepsy and with no learning disability, these participants have practically no correlation between their quality of life and academic self-concept. Our findings suggest that considerable attention should be paid to children having both epilepsy and learning disability. It should comprise services of specialized counselors and teaching assistants with an appropriate knowledge of epilepsy and ability to empathize with these children as well as educational interventions focused on their teachers

    Full Text Available The childhood epilepsy is a chronic disease that can have an impact in various spheres of life of the child, including academic performance and school attendance. This study aimed to describe and compare the school attendance of children with epilepsy who attend mainstream and special schools. Participants were 56 children aged between 7 and 14 years who attended regular or special schools located in two Brazilian cities of medium size. To collect the information we used two instruments: Data sheet of identification and characterization of the child and Data sheet to record the attendance school. The results showed that children in special schools had higher rates of absenteeism compared to students in regular schools. Additionally, we observed that these children use more drugs and have implications on health more severe than children in regular schools. Thus, it is the childhood epilepsy as a disease complex that brings substantial effects on various areas of children’s lives by reinforcing the need for studies that might expand the knowledge to and the experiences associated with the education of these children.

    Long-acting benzodiazepines such as chlordiazepoxide are recommended as first-line treatment for alcohol withdrawal. These drugs are known for their abuse liability and might increase alcohol consumption among problem drinkers. Phenobarbital could be an alternative treatment option, possibly with the drawback of a more pronounced acute toxicity. We evaluated if phenobarbital compared to chlordiazepoxide decreased the risk of subsequent use of benzodiazepines, alcohol recidivism and mortality. The study was a register-based cohort study of patients admitted for alcohol withdrawal 1998-2013 and treated with either phenobarbital or chlordiazepoxide. Patients were followed for one year. We calculated hazard ratios (HR) for benzodiazepine use, alcohol recidivism and mortality associated with alcohol withdrawal treatment, while adjusting for confounders. A total of 1063 patients treated with chlordiazepoxide and 1365 patients treated with phenobarbital were included. After one year, the outcome rates per 100 person-years in the phenobarbital versus the chlordiazepoxide cohort were 9.20 vs. 5.13 for use of benzodiazepine, 37.9 vs. 37.9 for alcohol recidivism and 29 vs. 59 for mortality. Comparing phenobarbital to chlordiazepoxide treated, the HR of subsequent use of benzodiazepines was 1.56 (95%CI 1.05-2.30). Similarly, the HR for alcohol recidivism was 0.99 (95%CI 0.84-1.16). Lastly, the HR for 30-days and 1 year mortality was 0.25 (95%CI 0.08-0.78) and 0.51 (95%CI 0.31-0.86). There was no decreased risk of subsequent benzodiazepine use or alcohol recidivism in patients treated with phenobarbital compared to chlordiazepoxide. Phenobarbital treatment was associated with decreased mortality, which might be confounded by somatic comorbidity among patients receiving chlordiazepoxide. Copyright © 2016 Elsevier Ireland Ltd.

    Creativity can be defined as the ability to understand, develop, and express, in a systematic fashion, novel orderly relationships. It is sometimes difficult to separate cognitive skills requisite for the creative process from the drive that generates unique new ideas and associations. Epilepsy itself may affect the creative process. The treatment of epilepsy and its comorbidities, by altering or disrupting the same neural networks through antiseizure drugs (ASDs), treatment of epilepsy comorbidities, ablative surgery, or neurostimulation may also affect creativity. In this review, we discuss the potential mechanisms by which treatment can influence the creative process and review the literature on the consequences of therapy on different aspects of creativity in people with epilepsy.

    The prescription pattern of antiepileptic drugs (AEDs) during pregnancy is changing but to what extent this is occurring in Spain remains unknown. The efficacy of newer drugs for controlling seizures is a key issue and may have changed over the years as doctors gained familiarity with these drugs during pregnancy. To assess these 2 topics, we report the results from the Spanish EURAP register gathered over a 12-year period. After signing informed consent forms, patients were included in the register and evaluated at onset of pregnancy, at the end of the second and third trimesters, after delivery, and one year after delivery. For the purposes of this study, we analysed AEDs, type of epilepsy, seizure frequency per trimester and throughout pregnancy, percentage of seizure-free pregnancies, and frequency of congenital malformations. We then compared data from 2 periods (June 2001-October 2007) and (January 2008-May 2015) RESULTS: We compared 304 monotherapies from the older period to 127 from the more recent one. There was a clear increase in the use of levetiracetam (LEV) with declining use of carbamazepine (CBZ), phenytoin, and phenobarbital; a slight decline in use of valproate (VPA), and a slight increase in the use of lamotrigine (LTG) and oxcarbazepine (OXC). Epilepsy types treated with CBZ and VPA remained unchanged, whereas fewer cases of generalised epilepsy were treated with LTG in the new period. This trend was not associated with significant changes in seizure frequency, but rather linked to better control over de novo seizures in the third trimester. LEV was similar to CBZ and VPA with regard to levels of seizure control, and more effective than LTG. Generalised epilepsy accounted for 64% of the cases treated with LEV. The prescription pattern of AEDs during pregnancy has changed in Spain, with diminishing use of CBZ, phenytoin, and phenobarbital. Changes also reflect the type of epilepsy, since there is less use of LTG for generalised epilepsy. LEV

    Entomotoxicology is focused on obtaining data on necrophagous entomofauna, for criminal investigations purposes. This study aimed to evaluate the effect of different concentrations of methylphenidate hydrochloride, phenobarbital, and their association on the developmental rate, larval and pupal survivorship, and the interval of emergence of adults of Chrysomya albiceps (Wiedemann), Chrysomya megacephala (Fabricius), and Chrysomya putoria (Wiedemann) (Diptera: Calliphoridae). Considering the therapeutic dose (TD) of methylphenidate hydrochloride (0.29 mg/Kg), the concentrations tested were 10× TD, 50× TD, and 100× TD. For phenobarbital, the concentrations used were 1× TD (=150 mg/Kg), 3.3× TD, and 6.7× TD. For the association of the drugs, the combinations used were 10× TD-methylphenidate hydrochloride plus 1× TD-phenobarbital, 50× TD-methylphenidate hydrochloride plus 3.3× TD-phenobarbital, and 100× TD-methylphenidate hydrochloride plus 6.7× TD-phenobarbital. The control group, without addition of drug, was maintained under the same conditions of temperature (25 ± 1 °C), humidity (70 ± 10%), and photoperiod (12 h). Specimens of each group were weighed every 12 h until pupariation. The developmental rate of the three Chrysomya species immatures was monitored. For C. albiceps the developmental time was delayed in 24 h for methylphenidate hydrochloride group and in 12 h for the phenobarbital and the drugs association groups. The effect was observed only at specific ages for C. megacephala, without altering the developmental time. For C. putoria, the developmental time was delayed in 12 h for methylphenidate hydrochloride group and in 24 h for the phenobarbital and the drugs association groups. The emergence interval was similar among all experimental groups, but larval and pupal viabilities were affected in different ways.

    Full Text Available Purpose: To describe the clinical features and outcome of febrile infection-related epilepsy syndrome (FIRES, a catastrophic epileptic encephalopathy, in a cohort of South Indian children. Materials and Methods: We performed a retrospective chart review of a cohort of children with previously normal development who presented with status epilepticus or encephalopathy with recurrent seizures following a nonspecific febrile illness during the period between January 2007 and January 2012. They were divided into two groups super refractory status epilepticus (SRSE and refractory status epilepticus (RSE depending on the duration and severity of the seizures. Key Findings: Fifteen children who met the inclusion criteria were included for the final analysis. The age of the children at presentation ranged 3-15 years (median 6.3 years. All the children presented with prolonged or recurrent seizures occurring 1-12 days (median 4 days after the onset of fever. Eight children had SRSE while seven children had refractory seizures with encephalopathy. Cerebrospinal fluid (CSF analysis was done in all the children in the acute phase, and the cell count ranged 0-12 cells/μL (median 2 cells/μL with normal sugar and protein levels. Initial neuroimaging done in all children (MRI in 10 and CT in 5, and it was normal in 13 children. Treatment modalities included multiple antiepileptic drugs (AEDs (4-9 drugs (median 5 drugs. Midazolam (MDZ infusion was administered in seven patients. Eight patients required barbiturate coma to suppress the seizure activity. The duration of the barbiturate coma ranged 2-90 days (median 3 days. Steroids were used in 14 children and intravenous immunoglobulin (2 g/kg in 7 children. Three children died in the acute phase. All children were maintained on multiple AEDs till the last follow-up, the number of AEDs ranged 1-6 (median 5 AEDs. The patients with super refractory status in the acute phase were found to be more severely disabled

    To determine if epilepsy surgery is effective in improving the quality of life (QOL) of children with intractable seizures using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The authors conducted a prospective study of the families of 35 children with intractable epilepsy who underwent epilepsy surgery. Parents completed the QOLCE preoperatively and again 6 to 18 months after surgery. At both assessment dates parents indicated the severity of their child's seizures during the past 6 months and the frequency of their child's seizures during the past 4 weeks on Likert-type scales. Children were split into two groups according to surgery outcome: seizure free vs persistent seizures. Statistical analyses were conducted to determine if children rendered seizure free showed a greater improvement in QOL compared to those with persistent seizures postoperatively. Greater improvement in QOL was documented for children rendered seizure free vs children with persistent seizures. This was significant for the overall QOLCE QOL score and subscales assessing cognitive, social, emotional, behavioral, and physical domains of life. Epilepsy surgery improves the quality of life of children rendered seizure free. Families can be counseled preoperatively of the potential benefits of surgery beyond seizure reduction.

    Children with epilepsy are reported to be at a greater risk of injuries compared with their peers who do not have epilepsy. We set out to determine the frequency and pattern of seizure-related injuries in children with epilepsy seen at the University College Hospital (UCH), Ibadan, Nigeria. Consecutive cases of epilepsy seen at the pediatric neurology clinic of the UCH, Ibadan over a period of 6months were evaluated for injuries in the preceding 12months using a structured questionnaire. These were compared with age- and sex-matched controls. A total of 125 children with epilepsy and 125 age- and sex-matched controls were studied. Injuries occurred more frequently in children with epilepsy than in their peers (p=0.01, OR 1.935, 95% CI 1.142-3.280). Epilepsy was generalized in 80 (64.0%), and localization-related in 45 (36.0%). Idiopathic epilepsy accounted for 74 (59.2%), and the remaining 51 (40.8%) had remote symptomatic epilepsy. Fifty-seven (45.6%) children had suffered seizure-related injuries with multiple injuries in 31 (24.8%). The most frequent were skin/soft tissue lacerations (26.4%), injuries to the tongue and soft tissues of the mouth (19.2%), minor head injuries (15.2%), and dental injuries with tooth loss (8.0%). There was a statistically significant association between seizure frequency and seizure-related injuries (p=0.002). Children on polytherapy had a significantly higher frequency of seizure-related injuries (pEpilepsy is a major risk factor for injuries in childhood. High seizure frequency increases the risk of multiple injuries in children with epilepsy. Copyright © 2015 Elsevier Inc. All rights reserved.

Studies were identified through electronic Embase®, Cochrane©, MEDLINE®, and PubMed® databases. Manual review of bibliographies allowed for the detection of additional articles.Results: Our search yielded 65 articles. These articles contained information relevant to epidemiology (n = 16, treatment guidelines (n = 4, treatment patterns (n = 33, unmet needs (n = 4, and economics (n = 8. From a patient perspective, patients with less than or equal to two adverse events (AEs while taking anti-epileptic drugs (AEDs had significantly lower annual costs than those having greater than or equal to three AEs, as did patients with fewer seizures. The overall mean annual cost for epilepsy per patient ranged from US$773 in China to US$2646 in Mexico. Prevalence data varied widely and were found for countries including Arab League Members, China, India, and Taiwan. In Turkey, active prevalence rates ranged from 0.08/1000 to 8.5/1000, and in Arab countries, active prevalence ranged from 0.9/1000 in Sudan to 6.5/1000 in Saudi Arabia. Seventeen different AEDs were used in the identified studies. The most common AEDs utilized were phenobarbital (21.7%, valproate (17.5%, and tiagabine (16.4%. In all studies, the use of AEDs resulted in an increase of patients who became seizure free and a reduction in seizure frequency and severity.Conclusion: Few studies have examined the prevalence and incidence of epilepsy in emerging markets and study limitations tend to

    Acute alcohol withdrawal syndrome (AAWS) is encountered in patients presenting acutely to the Emergency Department (ED) and often requires pharmacologic management. We investigated whether a single dose of intravenous (i.v.) phenobarbital combined with a standardized lorazepam-based alcohol withdrawal protocol decreases intensive care unit (ICU) admission in ED patients with acute alcohol withdrawal. This was a prospective, randomized, double-blind, placebo-controlled study. Patients were randomized to receive either a single dose of i.v. phenobarbital (10 mg/kg in 100 mL normal saline) or placebo (100 mL normal saline). All patients were placed on the institutional symptom-guided lorazepam-based alcohol withdrawal protocol. The primary outcome was initial level of hospital admission (ICU vs. telemetry vs. floor ward). There were 198 patients enrolled in the study, and 102 met inclusion criteria for analysis. Fifty-one patients received phenobarbital and 51 received placebo. Baseline characteristics and severity were similar in both groups. Patients that received phenobarbital had fewer ICU admissions (8% vs. 25%, 95% confidence interval 4-32). There were no differences in adverse events. A single dose of i.v. phenobarbital combined with a symptom-guided lorazepam-based alcohol withdrawal protocol resulted in decreased ICU admission and did not cause increased adverse outcomes.

    Aloe vera is a medicinal plant that has been traditionally used to accelerate wound healing. Olive oil is also a natural product that may contribute to wound healing owing to its antimicrobial and anti-inflammatory effects. The present study aimed to evaluate the effect of an Aloe vera-olive oil (AVO) combination cream on the healing process of chronic wounds. In this randomised, double-blind, comparator-controlled, parallel-group trial, patients with chronic wounds were treated with either AVO cream or phenytoin cream as the standard treatment for a period of 30 days. Wound healing was evaluated using Bates-Jensen assessment tool and the severity of pain was assessed using a visual analogue scale (VAS). After initial assessment, 60 patients with chronic wounds (41 with pressure ulcer, 13 with diabetic wounds and 6 with venous ulcers), were recruited and randomised into 2 groups of 30. After 30 days of treatment, significant improvements in the wound size, depth, and edges; necrotic tissue type and amount; exudate type and amount; colour of wound surroundings; and peripheral tissue oedema score were observed in the AVO cream group (p<0.001). The total score of wound healing showed significant improvement with both AVO (p<0.001) and phenytoin (p<0.01) creams, although AVO was more efficacious (p<0.001). Likewise, although both treatments reduced the initial VAS score, the efficacy of AVO was significantly greater (p<0.001). AVO cream significantly accelerates biological healing of chronic wounds and helps to reduce pain severity with a higher efficacy compared with phenytoin cream.

    The male:female ratio in autism spectrum disorder (ASD) averages greater than 4:1 while the male:female ratio of ASD with epilepsy averages less than 3:1. This indicates an elevated risk of epilepsy in females with ASD; yet, it is unknown whether phenotypic features of epilepsy and ASD differ between males and females with this comorbidity. The goal of this study is to investigate sex differences in phenotypic features of epilepsy and ASD in a prospective sample of 130 children and young adults with an initial ASD diagnosis and subsequent epilepsy diagnosis. All participants were characterized by standardized diagnostic inventories, parent/caregiver completed questionnaires, and medical/academic record review. Diagnostic classifications of epilepsy, ASD, and intellectual disability were performed by board certified neurologists and a pediatric neuropsychologist. Results demonstrated a lower male:female ratio (1.8:1) in individuals with ASD and treatment-resistant epilepsy relative to those with ASD and treatment-responsive epilepsy (4.9:1), indicating a higher risk of treatment-resistant epilepsy in females. Mild neuroimaging abnormalities were more common in females than males and this was associated with increased risk of treatment-resistance. In contrast, ASD symptom severity was lower in females compared with males. Findings distinguish females with ASD and epilepsy as a distinct subgroup at higher risk for a more severe epilepsy phenotype in the context of a less severe ASD phenotype. Increased risk of anti-epileptic treatment resistance in females with ASD and epilepsy suggests that comprehensive genetic, imaging, and neurologic screening and enhanced treatment monitoring may be indicated for this subgroup.

    In this prospective study the early cognitive development of children born to women with epilepsy (n = 198) was assessed and compared to a group of children representative of the general population (n = 230). The children were assessed when younger than the age of 2 years using the Griffiths Mental Development Scales, either in their local participating hospital or in their home. The assessments were completed by an assessor who was blinded to whether the child's mother had epilepsy and to antiepileptic drug type. Children exposed to sodium valproate had a statistically significant increased risk of delayed early development in comparison to the control children. Linear regression analysis showed a statistically significant effect of sodium valproate exposure on the child's overall developmental level that was not accounted for by confounding variables. Delayed early development is also noted for children within an ad hoc group of less commonly utilized antiepileptic drugs, although conclusions cannot be drawn due to the size of this group (n = 13). Children exposed to either carbamazepine or lamotrigine in utero did not differ significantly in their overall developmental ability. Differences noted in specific developmental areas for these two groups were not statistically significant after the control for confounders such as socioeconomic status and maternal IQ. Women with epilepsy should be informed of the risks posed to their potential offspring prior to pregnancy to allow for informed decisions regarding treatment. Children exposed in utero to antiepileptic drugs should be monitored throughout childhood to allow for early intervention when necessary.

    Epilepsy Action Australia conducted an Australian nationwide online survey seeking opinions on and experiences with the use of cannabis-based products for the treatment of epilepsy. The survey was promoted via the Epilepsy Action Australia's main website, on their Facebook page, and by word of mouth. The survey consisted of 39 questions assessing demographics, clinical factors, including diagnosis and seizure types, and experiences with and opinions towards cannabis use in epilepsy. A total of 976 responses met the inclusion criteria. Results show that 15% of adults with epilepsy and 13% of parents/guardians of children with epilepsy were currently using, or had previously used, cannabis products to treat epilepsy. Of those with a history of cannabis product use, 90% of adults and 71% of parents reported success in reducing seizure frequency after commencing cannabis products. The main reasons for medicinal cannabis use were to manage treatment-resistant epilepsy and to obtain a more favorable side-effect profile compared to standard antiepileptic drugs. The number of past antiepileptic drugs tried was a significant predictor of medicinal cannabis use in both adults and children with epilepsy. Fifty-six percent of adults with epilepsy and 62% of parents/guardians of children with epilepsy expressed willingness to participate in clinical trials of cannabinoids. This survey provides insight into the use of cannabis products for epilepsy, in particular some of the likely factors influencing use, as well as novel insights into the experiences of and attitudes towards medicinal cannabis in people with epilepsy in the Australian community.

    Full Text Available Contraception is an important choice that offers autonomy to women with regard to prevention of unintended pregnancies. There is wide variation in the contraceptive practices between continents, countries, and societies. The medical eligibility for contraception for sexually active women with epilepsy (WWE is determined by the type of anti-epileptic drugs (AEDs that they use. Enzyme inducing AEDs such as phenobarbitone, phenytoin, carbamazepine, and oxcarbazepine increase the metabolism of orally administered estrogen (and progesterone to a lesser extent. Estrogen can increase the metabolism of certain AEDs, such as lamotrigine, leading to cyclical variation in its blood level with resultant adverse effect profile or seizure dyscontrol. AEDs and sex hormones can increase the risk of osteoporosis and fracture in WWE. The potential interactions between AEDs and hormonal contraception need to be discussed with all women in reproductive age-group. The alternate options of oral contraception such as intrauterine copper device, intrauterine levonorgestrel release system, and supplementary protection with barriers need to be presented to them. World Health Organization has recommended to avoid combination contraceptive pills containing estrogen and progesteron in women who desire contraception and in breastfeeding mothers. Care providers need to consider the option of non-enzyme-inducing AEDs while initiating long-term treatment in adolescent and young WWE.

    The objective was to investigate the prevalence of attention-deficit hyperactivity disorder (ADHD) in children with frontal lobe epilepsy and related factors. The medical records of 190 children diagnosed with frontal lobe epilepsy at Qilu Hospital of Shandong University between 2006 and 2011 were retrospectively collected, and a follow-up analysis of the prevalence of ADHD in these children was conducted. Of the 161 children with an effective follow-up, 59.0% (95/161) with frontal lobe epilepsy suffered from ADHD as well. Analysis of epilepsy and ADHD-related factors indicated that the incidence of ADHD was 89.4% (76/85) in children with abnormal electroencephalogram (EEG) discharges on the most recent EEG, which was significantly higher than the ADHD incidence of 25% (19/76) in children with normal readings on the most recent EEG (P Children with frontal lobe epilepsy have a high incidence of ADHD. Sustained abnormal discharge on the electroencephalogram is associated with increased comorbidity of ADHD with frontal lobe epilepsy.

    Yeou-mei Christiana Liu

    2013-02-01

    Full Text Available The ketogenic diet (KD is one of the most effective therapies for drug-resistant epilepsy. The efficacy of the medium-chain triglyceride KD (MCTKD is as excellent as the classic KD (CKD, which has been documented in several subsequent retrospective, prospective, and randomized studies. MCT oil is more ketogenic than long-chain triglycerides. Therefore, the MCTKD allows more carbohydrate and protein food, which makes the diet more palatable than the CKD. The MCTKD is not based on diet ratios as is the CKD, but uses a percentage of calories from MCT oil to create ketones. There has also been literature which documents the associated gastrointestinal side effects from the MCTKD, such as diarrhea, vomiting, bloating, and cramps. Therefore, the MCTKD has been an underutilized diet therapy for intractable epilepsy among children.The author has used up to >70% MCTKD diet to maximize seizure control with gastrointestinal side effects optimally controlled. As long as health care professionals carefully manage MCTKD, many more patients with epilepsy who are not appropriate for CKD or modified Atkins diet or low glycemic index treatment will benefit from this treatment. A comparison between the MCTKD and other KDs is also discussed.

    Full Text Available Background: There is a lack of knowledge about epilepsy among the students and the population in general, with consequent prejudice and discrimination toward epileptic patients. Objectives: Knowledge, behavior, attitude and myth toward epilepsy among urban school children in Bareilly district was studied. Materials and Methods: A cross-sectional survey was conducted among students of 10 randomly selected secondary schools of the urban areas in Bareilly district. A structured, pretested questionnaire was used to collect data regarding sociodemographic characteristics and assess the subject′s knowledge, behavior, attitude and myth toward epilepsy. Results: Of the 798 students (533 boys and 265 girls studied, around 98.6% had heard of epilepsy. About 63.7% correctly thought that epilepsy is a brain disorder while 81.8% believed it to be a psychiatric disorder. Other prevalent misconceptions were that epilepsy is an inherited disorder (71.55% and that the disease is transmitted by eating a nonvegetarian diet (49%. Most of them thought that epilepsy can be cured (69.3 and that an epileptic patient needs lifelong treatment (77.2. On witnessing a seizure, about 51.5% of the students would take the person to the hospital. Majority (72.31% of the students thought that children with epilepsy should study in a special school. Conclusions: Although majority of the students had reasonable knowledge of epilepsy, myths and superstitions about the condition still prevail in a significant proportion of the urban school children. It may be worthwhile including awareness programs about epilepsy in school education to dispel misconceptions about epilepsy.

    The aim of this study was to assess the effects of oxcarbazepine (OXC) on cognition and psychosocial difficulties in patients with new-onset partial epilepsy. Cognitive and psychosocial assessments were performed before and after 6 to 12 months of OXC monotherapy in 52 drug-naive patients (25 women; mean age, 31.1 years; SD, 12.1 years). Cognitive functions were evaluated with well-structured and validated tools. Mood, psychological distress, subjective handicap, and quality of life were also evaluated. Differences between baseline and after-treatment evaluation were compared and adjusted for possible confounders such as age, sex, seizure control, duration of epilepsy, assessment interval, and epileptogenic region. Mean assessment interval was 231.8 (range, 182-348) days, and mean (SD) OXC dose at retest was 693.8 (208.9) mg. The OXC was found to have no significant adverse effect on cognition. Furthermore, OXC monotherapy was not found to affect psychosocial difficulties, including psychological distress and subjective handicap. The results suggest that OXC monotherapy could be used to treat newly diagnosed partial epilepsy without adversely affecting cognitive and psychosocial functions.

    Previous work has indicated an association between seizures early in life and increased risk of psychiatric disorders, including schizophrenia. However, because early-life seizures are commonly treated with antiepileptic drugs (AEDs) such as phenobarbital, the possibility that drug treatment may affect later-life psychiatric outcomes needs to be evaluated. We therefore tested the hypothesis that phenobarbital exposure in the neonatal rat increases the risk of schizophrenia-like behavioral abnormalities in adulthood. Thus, in this study, we examined the effects of a single acute neonatal exposure to phenobarbital on adult behavioral outcomes in the rat neonatal ventral hippocampal (nVH) lesion model of schizophrenia. We compared these outcomes to those in rats a) without nVH lesions and b) with nVH lesions, without phenobarbital. The tasks used for behavioral evaluation were: amphetamine-induced locomotion, prepulse inhibition, elevated plus-maze, and novel object recognition task. We found that neonatal phenobarbital treatment (in the absence of nVH lesions) was sufficient to disrupt sensorimotor gating (as tested by prepulse inhibition) in adulthood to an extent equivalent to nVH lesions. Additionally, neonatal phenobarbital exposure enhanced the locomotor response to amphetamine in adult animals with and without nVH lesions. Our findings suggest that neonatal exposure to phenobarbital can predispose to schizophrenia-like behavioral abnormalities. Our findings underscore the importance of examining AED exposure early in life as a potential risk factor for later-life neuropsychiatric abnormalities in clinical populations.

    Epilepsy care for children has been criticised for its lack of impact. Various service models and strategies have been developed in response to perceived inadequacies in care provision for children and their families. To compare the effectiveness of any specialised or dedicated intervention for the care of children with epilepsy and their families to the effectiveness of usual care. We searched the Cochrane Epilepsy Group Specialized Register (9 December 2013), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, 2013,Issue 11), MEDLINE (1946 to June week 2, 2013), EMBASE (1988 to week 25, 2013), PsycINFO (1887 to 11 December 2013) and CINAHL Plus (1937 to 11 December 2013). In addition, we contacted experts in the field to seek information on unpublished and ongoing studies, checked the websites of epilepsy organisations and checked the reference lists of included studies. We included randomised controlled trials (RCTs), controlled or matched trials, cohort studies or other prospective studies with a control group (controlled before-and-after studies), or time series studies. Each review author independently selected studies, extracted data and assessed the quality of included studies. We included five interventions reported in seven study reports (of which only four studies of three interventions were designed as RCTs) in this review. They reported on different education and counselling programmes for children, children and parents, teenagers and parents, or children, adolescents and their parents. Each programme showed some benefits for the well-being of children with epilepsy, but each study had methodological flaws (e.g. in one of the studies designed as an RCT, randomisation failed) and no single programme was independently evaluated by more than one study. While each of the programmes in this review showed some benefit to children with epilepsy, their impacts were extremely variable. No programme showed benefits across the full

From 1998 to 2006, 14/242 patients with benign children epilepsy with centrotemporal spikes (BECTS) were diagnosed as having ABPE with ENM. In all 14 patients, we performed video-EEG monitoring along with tests with the patient's arms outstretched; 6/14 patients were also simultaneously underwent surface electromyogram (EMG). ENM manifestations, electrophysiological features, and responses to antiepileptic drugs were analyzed. In all cases, ENM developed after the onset of epilepsy and during antiepileptic drug therapy, and the appearance of ENM were corresponding to EEG findings of high-amplitude spikes followed by a slow wave in the contralateral motor areas with secondary generalization. This was further confirmed by time-locked silent EMG. During ENM occurrence or recurrence, habitual seizures and interictal discharges were exaggerated. In some patients, the changes in antiepileptic drug regimens in relation to ENM appearance included add-on therapy with carbamazepine, oxcarbazepine, and phenobarbital or withdrawal of valproate. ENM was controlled in most cases by administration of various combinations of valproate, clonazepam, and corticosteroids. The incidence of ENM or ABPE in our center was approximately 5.79%. A combination of video-EEG monitoring with the patient's arms outstretched and EMG is essential to identify ENM. The aggravation of habitual seizures and interictal discharges indicate ENM. Some antiepileptic drugs, such as carbamazepine, oxcarbazepine, and phenobarbital, may be related to ENM occurrence during spontaneous aggravation of ABPE. Various combinations of valproate, benzodiazepines, and corticosteroids are relatively effective for treating ENM that occurs in ABPE.

    Full Text Available ABSTRACT The ketogenic diet (KD, a high-fat, low-carbohydrate, and adequate-protein diet is an established, effective nonpharmacologic treatment option for intractable childhood epilepsy. The KD was developed in 1921 and even though it has been increasingly used worldwide in the past decade, many neurologists are not familiar with this therapeutic approach. In the past few years, alternative and more flexible KD variants have been developed to make the treatment easier and more palatable while reducing side effects and making it available to larger group of refractory epilepsy patients. This review summarizes the history of the KD and the principles and efficacy of the classic ketogenic diet, medium-chain triglyceride(s (MCT ketogenic diet, modified Atkins diet, and low glycemic index treatment.

    Abstract We compared persistence of antiepileptic drugs (AEDs) including carbamazepine, oxcarbazepine, gabapentin, lamotrigine, topiramate, valproic acid, and phenytoin in an Asian population with epilepsy. A retrospective cohort study was conducted by analyzing Taiwan's National Health Insurance Research Database (NHIRD). Adult epilepsy patients newly prescribed with AEDs between 2005 and 2009 were included. The primary outcome was persistence, defined as the treatment duration from the date of AED initiation to the date of AED discontinuation, switching, hospitalization due to seizure or disenrollment from databases, whichever came first. Cox proportional hazard models were used to estimate the risk of non-persistence with AEDs. Among the 13,061 new users of AED monotherapy (mean age: 58 years; 60% men), the persistence ranged from 218.8 (gabapentin) to 275.9 (oxcarbazepine) days in the first treatment year. The risks of non-persistence in patients receiving oxcarbazepine (adjusted hazard ratio [HR], 0.78; 95% CI, 0.74–0.83), valproic acid (0.88; 0.85–0.92), lamotrigine (0.72; 0.65–0.81), and topiramate (0.90; 0.82–0.98) were significantly lower than in the carbamazepine group. Compared with carbamazepine users, the non-persistence risk was higher in phenytoin users (1.10; 1.06–1.13), while gabapentin users (1.03; 0.98–1.09) had similar risk. For risk of hospitalization due to seizure and in comparison with carbamazepine users, oxcarbazepine (0.66; 0.58–0.74) and lamotrigine (0.46; 0.35–0.62) users had lower risk, while phenytoin (1.35; 1.26–1.44) users had higher risk. The results remained consistent throughout series of sensitivity and stratification analyses. The persistence varied among AEDs and was better for oxcarbazepine, valproic acid, lamotrigine, and topiramate, but worse for phenytoin when compared with carbamazepine. PMID:27583857

    Neonatal stroke presents with seizures that are usually treated with phenobarbital. We hypothesized that anticonvulsants would attenuate ischemic injury, but that the dose-dependent effects of standard anticonvulsants would impact important age-dependent and injury-dependent consequences. In this study, ischemia induced by unilateral carotid ligation in postnatal day 12 (P12) CD1 mice was immediately followed by an i.p. dose of vehicle, low-dose or high-dose phenobarbital. Severity of acute behavioral seizures was scored. 5-bromo-2’-deoxyuridine (BrdU) was administered from P18-P20, behavioral testing performed, and mice perfused at P40. Atrophy quantification and counts of BrdU/NeuN-labeled cells in the dentate gyrus were performed. Blood phenobarbital concentrations were measured. 30 mg/kg phenobarbital reduced acute seizures and chronic brain injury, and restored normal weight gain and exploratory behavior. By comparison, 60 mg/kg was a less efficacious anticonvulsant, was not neuroprotective, did not restore normal weight gain, and impaired behavioral and cognitive recovery. Hippocampal neurogenesis was not different between treatment groups. These results suggest a protective effect of lower-dose phenobarbital, but a lack of this effect at higher concentrations after stroke in P12 mice. PMID:21481568

    Syntaxin Binding Protein 1 (STXBP1) mutations determine a central neurotransmission dysfunction through impairment of the synaptic vesicle release, thus causing a spectrum of phenotypes varying from syndromic and non-syndromic epilepsy to intellectual disability of variable degree. Among the antiepileptic drugs, levetiracetam has a unique mechanism of action binding SV2A, a glycoprotein of the synaptic vesicle release machinery. We report a 1-month-old boy manifesting an epileptic encephalopathy with clonic seizures refractory to phenobarbital, pyridoxine and phenytoin that presented a dramatic response to levetiracetam with full epilepsy control and EEG normalization. Genetic analysis identified a novel de novo heterozygous mutation (c.[922A>T]p.[Lys308(∗)]) in the STXBP1 gene that severely affects the protein. The observation of a dramatic efficacy of levetiracetam in a case of STXBP1 epileptic encephalopathy refractory to other antiepileptic drugs and considerations regarding the specific mechanism of action of levetiracetam modulating the same system affected by STXBP1 mutations support the hypothesis that this drug may be able to reverse specifically the disease epileptogenic abnormalities. Further clinical observations and laboratory studies are needed to confirm this hypothesis and eventually lead to consider levetiracetam as the first choice treatment of patients with suspected or confirmed STXBP1-related epilepsies.

    Children with epilepsy and their parents face many social and psychological difficulties that remain insufficiently studied in sub-Saharan Africa. The aim here was to assess the quality of life of children with epilepsy and their parents. A community-based cross-sectional survey was conducted in two urban areas and four rural areas of Gabon. Children were screened through key informants, medical sources, and a door-to-door survey. They were clinically selected based on their medical history and a clinical exam conducted by the investigating physician. Electroencephalography had not been carried out because of a lack of material and financial resources. The quality of life of children and their parents was assessed by a structured interview of parents using a questionnaire. Of 317 suspected cases on screening, 83 children with epilepsy were identified. Their mean age was 11.9±4.4years. Twelve percent of the children had neurosensory abnormalities on clinical exam. Sixty-three percent of them attended school; factors associated with schooling were higher score on the sociability subscale, specialized medical advice, and antiepileptic drug treatment. Sociability difficulties, anxiety, cognitive impairment, and behavioral disorders were suspected in 39.8%, 45.8%, 49.4%, and 42.2% of children, respectively. A total of 48.2% of parents expressed a poor quality of life related to their children's illness. A higher score on the cognition subscale, urban residence, specialized medical advice, and a stable income in the household were predictive of poor parental quality of life. Epilepsy influences many aspects of a child's life and the life of the child's parents. Care should incorporate a cognitive assessment of the child and emphasize information for patients and their relatives. Copyright © 2015 Elsevier Inc. All rights reserved.

    Purpose Epilepsy is common in sub-Saharan Africa (SSA), but the clinical features and consequences are poorly characterized. Most studies are hospital-based, and few studies have compared different ecological sites in SSA. We described active convulsive epilepsy (ACE) identified in cross-sectional community-based surveys in SSA, to understand the proximate causes, features, and consequences. Methods We performed a detailed clinical and neurophysiologic description of ACE cases identified from a community survey of 584,586 people using medical history, neurologic examination, and electroencephalography (EEG) data from five sites in Africa: South Africa; Tanzania; Uganda; Kenya; and Ghana. The cases were examined by clinicians to discover risk factors, clinical features, and consequences of epilepsy. We used logistic regression to determine the epilepsy factors associated with medical comorbidities. Key Findings Half (51%) of the 2,170 people with ACE were children and 69% of seizures began in childhood. Focal features (EEG, seizure types, and neurologic deficits) were present in 58% of ACE cases, and these varied significantly with site. Status epilepticus occurred in 25% of people with ACE. Only 36% received antiepileptic drugs (phenobarbital was the most common drug [95%]), and the proportion varied significantly with the site. Proximate causes of ACE were adverse perinatal events (11%) for onset of seizures before 18 years; and acute encephalopathy (10%) and head injury prior to seizure onset (3%). Important comorbidities were malnutrition (15%), cognitive impairment (23%), and neurologic deficits (15%). The consequences of ACE were burns (16%), head injuries (postseizure) (1%), lack of education (43%), and being unmarried (67%) or unemployed (57%) in adults, all significantly more common than in those without epilepsy. Significance There were significant differences in the comorbidities across sites. Focal features are common in ACE, suggesting identifiable and

    Mental health problems and parental anxiety in children with epilepsy were investigated. Parents of 83 children with epilepsy and 172 healthy children were asked to complete Strengths and Difficulties Questionnaire for their children and State-Trait Anxiety Inventory for themselves. In those with epilepsy, 39.8% (n: 33) were girls, 60.2% (n: 50) were boys and their mean age was 9.34 ± 3.99 years. Control group was more successful in school (p children with epilepsy was higher than control group (p children with epilepsy were higher. Children with epilepsy have more neuro-behavioral problems; and their parents have greater anxiety levels. Physicians should be in contact with children with epilepsy for the psychological health of the family besides seizure control.

  19. Non-hyperammonaemic valproate encephalopathy after 20 years of treatment

    Full Text Available Sodium valproate is a commonly used antiseizure drug with broad indications for different seizuretypes and epilepsy syndromes. Well-recognised side effects include weight gain, tremor, dizziness, and unsteadiness. Non-hyperammonaemic parkinsonism, with or without cognitive impairment, is a rare adverse effect of sodium valproate. We present the case of a sixty year-old lady with a generalized seizure disorder, treated with phenytoin, valproate, lamotrigine and clonazepam. Following withdrawal of phenytoin she developed an akinetic-rigid syndrome, with ataxia and marked cognitive impairment. Extensive investigation failed to identify a cause. Serum ammonia and valproate levels were normal. Hypothesizing this might be valproate encephalopathy, valproate was rapidly substituted with levetiracetam. Her severe motor symptoms resolved within two weeks and cognitive impairment markedly improved. Valproate-induced encephalopathy, with or without hyperammonaemia and liver toxicity are typically recognizable for their temporal relation between the start of therapy with valproate and emergence of the clinical syndrome. Reversible disorders of motor function and cognition attributable to valproate are well described, but few cases have been reported presenting years after starting treatment. Given the insidious progression, delayed onset, lack of association with drug levels or presence of hyperammonaemia, a high index of suspicion is needed to make the diagnosis.

    Typical childhood development is characterized by the emergence of intrinsic connectivity networks (ICNs) by way of internetwork segregation and intranetwork integration. The impact of childhood epilepsy on the maturation of ICNs is, however, poorly understood. The developmental trajectory of ICNs in 26 children (8-17 years) with localization-related epilepsy and 28 propensity-score matched controls was evaluated using graph theoretical analysis of whole brain connectomes from resting-state functional magnetic resonance imaging (fMRI) data. Children with epilepsy demonstrated impaired development of regional hubs in nodes of the salience and default mode networks (DMN). Seed-based connectivity and hierarchical clustering analysis revealed significantly decreased intranetwork connections, and greater internetwork connectivity in children with epilepsy compared to controls. Significant interactions were identified between epilepsy duration and the expected developmental trajectory of ICNs, indicating that prolonged epilepsy may cause progressive alternations in large-scale networks throughout childhood. DMN integration was also associated with better working memory, whereas internetwork segregation was associated with higher full-scale intelligence quotient scores. Furthermore, subgroup analyses revealed the thalamus, hippocampus, and caudate were weaker hubs in children with secondarily generalized seizures, relative to other patient subgroups. Our findings underscore that epilepsy interferes with the developmental trajectory of brain networks underlying cognition, providing evidence supporting the early treatment of affected children.

    The action of phenytoin was studied in acute experiments in rats with brainstem transection at the midcollicular level. Symmetrical epileptogenic foci were elicited in sensorimotor cortical areas of both hemispheres by local application of penicillin. Seven rats formed a control group, ten animals were pretreated with phenytoin (60 mg/kg i.p., 10 min before penicillin application). Synchronization of interictal discharges in control rats was delayed in comparison to animals with an intact brainstem; phenytoin did not influence this synchronization. Spontaneous transition of interictal into ictal activity was not abolished by phenytoin, i.e. in cerveau isolé preparations phenytoin lost this activity. The loss of anticonvulsant activity was not complete. Ictal episodes were modified; they started as very short ones and their duration progressively increased. Structures localized below the level of transection represent a site of at least one of the mechanisms of phenytoin anticonvulsant action.

    Childhood epilepsy is common in Africa. However, there are little data on the developmental and behavioral problems experienced by children living with epilepsy, especially qualitative data that capture community perceptions of the challenges faced by these children. Identifying these perceptions using qualitative approaches is important not only to help design appropriate interventions but also to help adapt behavioral tools that are culturally appropriate. We documented the description of these problems as perceived by parents and teachers of children with or without epilepsy. The study involved 70 participants. Data were collected using in-depth interviews and focus group discussions and were analyzed using NVIVO to identify major themes. Our analysis identified four major areas that are perceived to be adversely affected among children with epilepsy. These included internalizing and externalizing problems such as aggression, temper tantrums, and excessive crying. Additionally, developmental delay, especially cognitive deficits and academic underachievement, was also identified as a major problematic area. There is a need to supplement these findings with quantitative estimates and to develop psychosocial and educational interventions to rehabilitate children with epilepsy who have these difficulties.

Data on epilepsy and febrile seizures were extracted from the Danish National Hospital Register. RESULTS......: Overall, children of subfertile couples (TTP > 12 months) had a 51% higher risk of epilepsy [incidence rate ratio (IRR): 1.51; 95% confidence interval (95% CI): 1.17-1.94] compared with children of couples with a TTP of 0-5 months. The corresponding estimates were 1.71 (95% CI: 1.21-2.42) if the couples...

    The history of epilepsy and its treatment in the western world dates back at least 4 millennia to the ancient civilization of the middle east. Past and present treatments have been empirical, usually reflecting the prevailing views of epilepsy, be they medical, theological or superstitious. Ancient physicians relied on clinical observation to distinguish between epileptic syndromes and infer their cause. Early pathophysiological theories of epilepsy correctly identified the brain as the site of the problem, but emphasized incorrect causes such as an excess of phlegm in the brain. Treatments consisted of prescribed diets or living conditions, occasional surgery such as bloodletting or skull trephination and medicinal herbs. These treatments, often ineffective, had the intellectual advantage of being based on pathophysiological principles, unlike current, more empirical, therapies. The unfortunate but widely held view of epilepsy as being due to occult or evil influences gained adherents even in the medical world during ancient times, and the later acceptance of Christianity allowed theological interpretations of seizures as well. Magical or religious treatments were more frequently prescribed as a result, practices which persist to this day. In the Renaissance an attempt was made to view epilepsy as a manifestation of physical illness rather than a moral or occult affliction, but it was during the Enlightenment that epilepsy was viewed along more modern lines, helped by advances in anatomy and pathology and the development of chemistry, pharmacy and physiology. The idea that focal irritation may cause seizures came about from clinical and experimental work, and was supported by the successful control of seizures by the (sedative) bromides and barbiturates in the late 19th century. The introduction of phenytoin showed that non-sedative drugs could be effective in controlling seizures as well, and the development of in vivo seizure models widened the scope of

    The rapid forgetting of information over long (but not short) delays (accelerated long-term forgetting [ALF]) has been associated with temporal lobe epilepsy but not idiopathic generalized epilepsy (IGE). Long-term memory formation (consolidation) is thought to demand an interaction between medial temporal and neocortical networks, which could be disrupted by epilepsy/seizures themselves. The present study investigates whether ALF is present in children with IGE and whether it relates to epilepsy severity. Sixty-one children (20 with IGE and 41 healthy controls [HC]) of comparable age, sex, and parental socioeconomic status completed neuropsychological tests, including a measure of verbal learning and recall after, short (30-min) and long (7-day) delays, and recognition. Epilepsy severity was rated by treating neurologists. A two-way repeated measures analysis of covariance (ANCOVA) found a significant Group x Delay interaction; the children with IGE recalled (and recognized) significantly fewer words after a long, but not short (2- and 30-min) delay relative to the HC children. Moreover, greater epilepsy severity was associated with poorer recognition. This study demonstrates, to our knowledge for the first time, that children with IGE present with ALF, which is related to epilepsy severity. These findings support the notion that epilepsy/seizures themselves may disrupt long-term memory consolidation, which interferes with day-to-day functioning of children with IGE.

    2017-01-01

    Full Text Available Although chronic vagus nerve stimulation (VNS is an established treatment for medically-intractable childhood epilepsy, there is considerable heterogeneity in seizure response and little data are available to pre-operatively identify patients who may benefit from treatment. Since the therapeutic effect of VNS may be mediated by afferent projections to the thalamus, we tested the hypothesis that intrinsic thalamocortical connectivity is associated with seizure response following chronic VNS in children with epilepsy. Twenty-one children (ages 5–21 years with medically-intractable epilepsy underwent resting-state fMRI prior to implantation of VNS. Ten received sedation, while 11 did not. Whole brain connectivity to thalamic regions of interest was performed. Multivariate generalized linear models were used to correlate resting-state data with seizure outcomes, while adjusting for age and sedation status. A supervised support vector machine (SVM algorithm was used to classify response to chronic VNS on the basis of intrinsic connectivity. Of the 21 subjects, 11 (52% had 50% or greater improvement in seizure control after VNS. Enhanced connectivity of the thalami to the anterior cingulate cortex (ACC and left insula was associated with greater VNS efficacy. Within our test cohort, SVM correctly classified response to chronic VNS with 86% accuracy. In an external cohort of 8 children, the predictive model correctly classified the seizure response with 88% accuracy. We find that enhanced intrinsic connectivity within thalamocortical circuitry is associated with seizure response following VNS. These results encourage the study of intrinsic connectivity to inform neural network-based, personalized treatment decisions for children with intractable epilepsy.

The case series presented here aim to highlight the difficult situation the affected children are in. We report on three cases when children have been traumatized and, in one case, even been killed by their parent who was diagnosed with epilepsy. In the first case, we describe a woman with juvenile myoclonic epilepsy who was sentenced to forensic psychiatry care for killing her child. She lived under difficult psychosocial circumstances and a suicide attempt contributed to what happened. The second case describes a man with post-traumatic seizures who was sentenced for child abuse. Ictal or postictal violence was considered in these two cases but a causal link between the violence and epilepsy has not been established. In the third case, we describe a woman with focal epilepsy and psychogenic non-epileptic seizures (PNESs. Her child was hurt and frightened in relation to violent seizures, which were regarded as PNESs. This case series demonstrates that children of parents with epilepsy can be in a vulnerable situation. No causality has been established between the seizures and these events, so consequently other factors such as psychosocial stress, low cognitive function, and a suicide attempt must also be considered as important. When a child is hurt by a parent with epilepsy the patient must be closely examined to determine the role of the seizures

    Full Text Available To estimate the prevalence of epilepsy in children with Autism Spectrum Disorder (ASD and to determine the demographic and clinical characteristics of children with ASD and epilepsy in a large patient population.Cross-sectional study using four samples of children with ASD for a total of 5,815 participants with ASD. The prevalence of epilepsy was estimated from a population-based sample. Children with and without epilepsy were compared on demographic and clinical characteristics. Multivariate logistic regression was used to examine the association between demographic and clinical characteristics and epilepsy.The average prevalence of epilepsy in children with ASD 2-17 years was 12.5%; among children aged 13 years and older, 26% had epilepsy. Epilepsy was associated with older age, lower cognitive ability, poorer adaptive and language functioning, a history of developmental regression and more severe ASD symptoms. The association between epilepsy and the majority of these characteristics appears to be driven by the lower IQ of participants with epilepsy. In a multivariate regression model, only age and cognitive ability were independently associated with epilepsy. Children age 10 or older had 2.35 times the odds of being diagnosed with epilepsy (p<.001 and for a one standard deviation increase in IQ, the odds of having epilepsy decreased by 47% (p<.001.This is among the largest studies to date of patients with ASD and co-occurring epilepsy. Based on a representative sample of children with ASD, the average prevalence of epilepsy is approximately 12% and reaches 26% by adolescence. Independent associations were found between epilepsy and older age and lower cognitive ability. Other risk factors, such as poor language and developmental regression, are not associated with epilepsy after controlling for IQ. These findings can help guide prognosis and alert clinicians to patients with ASD who are at increased risk for epilepsy.

    It is a general rule today, after a relevant diagnostics of an epilepsy, to start a monotherapy treatment, depending on a kind of a seizure, a life age and a general health condition. First line of monotherapy epilepsy drugs remain carbamazapine and sodium valproat. New drugs that are being introduced are: felbamat, gabapentin, lamotrigin, oxcarbazepin, tiagabin, topiramat, vigabatin and zanisamid. These are commonly used as add-on therapy, or as an addition for previously used antiepileptic. Their indicated areas are complex resistant partial seizures with or without generalization. Attention should be paid on proper dosage, interactions and toxicity. Regardless on the new epileptic era, according to reports of International League against epilepsy, most of the patients do not receive the drug that is the most appropriate for them concerning the price (cost-benefit). Neurosurgical methods in epilepsy treatment are: selective amygdalo-hyppocampotomy, temporal lobotomy, subpial resection, hemispherectomy, corpus callosotomy, removal of lesions like tumors or cysts provide encouraging results in reduction of epileptic seizures that can be followed by reduction of drug therapy. N. vagus stimulation is being wider introduced in resident epileptics. Treatment of epilepsy in women requires an approach to sexuality, conception, pregnancy, introduction of medicaments, antiepileptic terratogenity, contraception, motherhood and menopause. A special significance of modern approach to epilepsy is in treatment of elderly who have cerebrovascular and neurodegenerative disease as a cause of seizures. A complex treatment of epilepsy using pharmacological and neurosurgical approach requires supportive psychotherapy, socio-therapy, the work with a family, education about epilepsy and living a life with more quality having one.

    The purpose of this study was to use data from a population-based survey to evaluate the association between childhood epilepsy and social outcomes through tests of mathematics skills, and sense of general self-esteem (GSS). Using data from Cycles 1 to 8 of the National Longitudinal Survey of Children and Youth (NLSCY), Hierarchical linear modeling (HLM) was used to compare baseline math scores and changes in math scores and sense of general self esteem (GSS) over time in children with and without epilepsy. Scores of Health Utility Index (HUI) were factored into the analysis. Children with epilepsy do not significantly differ in their scaled math scores in comparison to their peers without epilepsy, at age 12; however, in the two level HLM model the children with epilepsy lagged behind the healthy comparison group in terms of their growth in acquiring knowledge in mathematics. Additionally, when children with epilepsy carry an added health impairment as measured by an imperfect health utility (HUI) score the group shows a slower rate of growth in their math scores over time. Self-esteem measures show variable effects in children with epilepsy alone, and those with added health impairments. The interaction with HUI scores shows a significant negative effect on self-esteem, when epilepsy is associated with added health impairment. The findings suggest that the population of Canadian children surveyed with epilepsy are vulnerable to poorer academic outcomes in mathematics in later years, and this problem is compounded further with the presence of other additional health impairments.

    In recent years there has been great scientific and public interest focused on the therapeutic potential of compounds derived from cannabis for the treatment of refractory epilepsy in children. From in vitro and in vivo studies on animal models, cannabidiol (CBD) appears to be a promising anticonvulsant drug with a favorable side-effect profile. In humans, CBD efficacy and safety is not supported by well-designed trials and its use has been described by anecdotal reports. It will be necessary to investigate CBD safety, pharmacokinetics and interaction with other anti-epileptic drugs (AEDs) alongside performing double-blinded placebo-controlled trials in order to obtain conclusive data on its efficacy and safety in children.

    Impairments in executive skills broadly span across multiple childhood epilepsy syndromes and can adversely affect quality of life. Bilingualism has been previously shown to correlate with enhanced executive functioning in healthy individuals. This study seeks to determine whether the bilingual advantage in executive functioning exists in the context of pediatric epilepsy. We retrospectively analyzed neuropsychological data in 52 children with epilepsy and compared executive function scores in monolingual versus bilingual children with epilepsy, while controlling for socioeconomic status and ethnicity. Bilingual children performed significantly better on the Working Memory scale than did monolingual children. There were no significant differences on the remaining executive function variables. The bilingual advantage appears to persist for working memory in children with epilepsy. These findings suggest that bilingualism is potentially a protective variable in the face of epilepsy-related working memory dysfunction. PMID:26720703

    The technique of EEG recording using subdural and depth electrodes has became established, and such invasive EEG is available for epilepsy surgery. However, a non-invasive procedure is required for evaluation of surgical indication for epilepsy patients, particular for children. We analyzed the relationship between the results of presurgical evaluation and seizure outcome, and investigated the role of invasive EEG in epilepsy surgery for children. Over the past decade, 22 children under 16 years of age have been admitted to our hospital for evaluation of surgical indication. High-resolution MR imaging, MR spectroscopy, video-EEG monitoring, and ictal and interictal SPECT were used for presurgical evaluation. Organic lesions were found on MR images from 19 patients. Invasive EEG was recorded in only one patient with occipital epilepsy, who had no lesion. Surgical indication was determined in 17 children, and 6 temporal lobe and 11 extratemporal lobe resections were performed under intraoperative electrocorticogram monitoring. The surgical outcome was excellent in 14 patients who had Engel's class I or II. Surgical complications occurred in two children who had visual field defects. The results showed that a good surgical outcome could be obtained using an intraoperative electrocorticogram, without presurgical invasive EEG, for localization-related epilepsy in children. The role of invasive EEG should be reevaluated in such children. (author)

    Given the FDA's warning regarding the potential connection between suicidal behavior and antiepileptic drugs, this study examined methods by which to detect suicidal ideation in children with epilepsy. It compared the sensitivity, specificity, and area under the curve for identifying children with suicidal behavior using the Child Behavior Checklist (CBCL) and a structured psychiatric interview. Parent-completed CBCLs provided behavioral problem scores on 177 children with epilepsy, aged 5-16years. Psychiatric diagnoses were made based on separate child and parent structured psychiatric interviews about the child. The children answered questions on suicidal behaviors during the interview. A clinically elevated score in the CBCL Total Problems scale and having more than one psychiatric diagnosis, irrespective of the type of diagnosis, were significant predictors and correctly classified children with suicidal ideation in 79% of the cases based on the CBCL and 80% of the cases with more than one psychiatric diagnosis. These findings indicate that elevated CBCL Total Problems scores, a commonly used instrument, can screen and identify risk for suicidal behavior in children with epilepsy. Additionally, irrespective of diagnosis, if a child with epilepsy has more than one psychiatric diagnosis, further assessment of suicidal behavior is warranted. Importantly, the results underscore the utility of having parents complete a questionnaire in the waiting room in order to identify children with epilepsy at risk for suicidal behavior. © 2013.

    Epilepsy may affect a child's social skills and social cognition. The purpose of the study was to examine associations between sociocognitive skills and neurocognitive performance in children with epilepsy. Thirty-five children with epilepsy between the ages of 7 and 12 years (25 with partial and 10 with generalized epilepsy) and 30 controls participated. Theory of Mind (ToM) tasks, Social Cognition Questionnaire proposed by Saltzman-Benaiah and Lalonde (2007), and Social Skills Rating System were used to assess social competence and sociocognitive skills. Neurocognitive performance was assessed using the NEPSY battery. Children with epilepsy demonstrated more difficulties in understanding false belief (pChildren with epilepsy performed significantly worse in attention, executive, verbal, and fine motor tasks (pChildren with generalized epilepsy had more problems in memory tasks (pchildren with partial epilepsy. An age of onset over 9.1 years was positively associated with ToM skills (r=.42, pchildren with better executive functions, and language and visuospatial skills was revealed. The type of epilepsy and age of onset significantly affected ToM skills. Copyright © 2015 Elsevier Inc. All rights reserved.

    The aim of this study was to evaluate demographic, clinical, and treatment factors that may impact on neurological adverse effects in naive and quasi-naive children and adolescents treated with antipsychotics. This was a 1-year, multicenter, observational study of a naive and quasi-naive pediatric population receiving antipsychotic treatment. Two subanalyses were run using the subsample of subjects taking the 3 most used antipsychotics and the subsample of antipsychotic-naive subjects. Total dyskinesia score (DyskinesiaS) and total Parkinson score (ParkinsonS) were calculated from the Maryland Psychiatric Research Center Involuntary Movement Scale, total UKU-Cognition score was calculated from the UKU Side Effect Rating Scale. Risk factors for tardive dyskinesias (TDs) defined after Schooler-Kaine criteria were studied using a logistic regression. Two hundred sixty-five subjects (mean age, 14.4 [SD, 2.9] years) with different Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders were recruited. DyskinesiaS (P < 0.001) and ParkinsonS (P < 0.001) increased at 1-year follow-up. Risperidone was associated with higher increases in DyskinesiaS compared with quetiapine (P < 0.001). Higher increases in ParkinsonS were found with risperidone (P < 0.001) and olanzapine (P = 0.02) compared with quetiapine. Total UKU-Cognition Score decreased at follow-up. Findings were also significant when analyzing antipsychotic-naive subjects. Fifteen subjects (5.8%) fulfilled Schooler-Kane criteria for TD at follow-up. Younger age, history of psychotic symptoms, and higher cumulative exposure time were associated with TD at follow-up. Antipsychotics increased neurological adverse effects in a naive and quasi-naive pediatric population and should be carefully monitored. Risperidone presented higher scores in symptoms of dyskinesia and parkinsonism. Quetiapine was the antipsychotic with less neurological adverse effects. Younger subjects, psychosis, and

    Epilepsy, a brain disorder leading to recurring seizures, has garnered increased public health focus because persons with epilepsy experience pronounced and persistent health and socioeconomic disparities despite treatment advances, public awareness programs, and expanded rights for persons with disabilities (1,2). For almost all states, epilepsy prevalence estimates do not exist. CDC used national data sources including the 2015 National Health Interview Survey (NHIS) for adults (aged ≥18 years), the 2011-2012 National Survey of Children's Health (NSCH), and the 2015 Current Population Survey data, describing 2014 income levels, to estimate prevalent cases of active epilepsy, overall and by state, to provide information for state public health planning. In 2015, 1.2% of the U.S. population (3.4 million persons: 3 million adults and 470,000 children) reported active epilepsy (self-reported doctor-diagnosed epilepsy and under treatment or with recent seizures within 12 months of interview) or current epilepsy (parent-reported doctor-diagnosed epilepsy and current epilepsy). Estimated numbers of persons with active epilepsy, after accounting for income and age differences by state, ranged from 5,900 in Wyoming to 427,700 in California. NHIS data from 2010-2015 indicate increases in the number of persons with active epilepsy, probably because of population growth. This study provides updated national and modeled state-specific numbers of active epilepsy cases. Public health practitioners, health care providers, policy makers, epilepsy researchers, and other epilepsy stakeholders, including family members and people with epilepsy, can use these findings to ensure that evidence-based programs meet the complex needs of adults and children with epilepsy and reduce the disparities resulting from it.

    The oral route is compromised for nearly all patients approaching death. When agitation, seizures, or other intractable symptoms occur, a quick, discreet, comfortable, and effective alternate route for medication delivery that is easy to administer in the home setting is highly desirable. To characterize the early absorption profile, variability, and comfort of phenobarbital given in microenema suspensions delivered via the Macy Catheter(®) (MC) vs. the same dose given via suppository. This was a randomized, open-label, crossover study comparing the early absorption profile of equal doses of phenobarbital administered rectally in three treatment phases: phenobarbital suppository and two different microenemas with phenobarbital tablets crushed and suspended in 6 mL (MC-6) or 20 mL (MC-20) of tap water. Mean plasma phenobarbital concentrations at 10 minutes were 12× higher for MC-20 and 8× higher for MC-6 compared to suppository. Concentrations achieved in 30 minutes via MC-20 took almost three hours to achieve with suppository. Mean AUC values were higher for MC-20 and MC-6 (82% and 46%, respectively) vs. suppository (P phenobarbital oral tablets crushed and suspended in water and administered via the MC is superior to suppository in delivering the medication reliably and rapidly.

    Disparities in epilepsy treatment are not uncommon; therefore, we examined population-based estimates of initial antiepileptic drugs (AEDs) in new-onset epilepsy among racial/ethnic minority groups of older US Medicare beneficiaries. We conducted retrospective analyses of 2008-2010 Medicare administrative claims for a 5% random sample of beneficiaries augmented for minority representation. New-onset epilepsy cases in 2009 had ≥1 International Classification of Diseases, Ninth Revision (ICD-9) 345.x or ≥2 ICD-9 780.3x, and ≥1 AED, AND no seizure/epilepsy claim codes or AEDs in preceding 365 days. We examined AED use and concordance with Quality Indicators of Epilepsy Treatment (QUIET) 6 (monotherapy as initial treatment = ≥30 day first prescription with no other concomitant AEDs), and prompt AED treatment (first AED within 30 days of diagnosis). Logistic regression examined likelihood of prompt treatment by demographic (race/ethnicity, gender, age), clinical (number of comorbid conditions, neurology care, index event occurring in the emergency room (ER)), and economic (Part D coverage phase, eligibility for Part D Low Income Subsidy [LIS], and ZIP code level poverty) factors. Over 1 year of follow-up, 79.6% of 3,706 new epilepsy cases had one AED only (77.89% of whites vs. 89% of American Indian/Alaska Native [AI/AN]). Levetiracetam was the most commonly prescribed AED (45.5%: from 24.6% AI/AN to 55.0% whites). The second most common was phenytoin (30.6%: from 18.8% Asians to 43.1% AI/AN). QUIET 6 concordance was 94.7% (93.9% for whites to 97.3% of AI/AN). Only 50% received prompt AED therapy (49.6% whites to 53.9% AI/AN). Race/ethnicity was not significantly associated with AED patterns, monotherapy use, or prompt treatment. Monotherapy is common across all racial/ethnic groups of older adults with new-onset epilepsy, older AEDs are commonly prescribed, and treatment is frequently delayed. Further studies on reasons for treatment delays are warranted

    Full Text Available Introduction Epilepsy is a prolonged disorder characterized by repeated violent epileptic seizures. Its managements depend on proper classification of the seizure category and the epileptic pattern. Levetiracetam (Keppra® has been approved as monotherapy or for adjunctive management of partial onset seizures, juvenile myoclonic epilepsy, and idiopathic generalized epilepsy. Case reporting of levetiracetam polypharmacy shows adverse effects linked to evidence-based clinical and laboratory data in two patients with epilepsy. Case reporting of levetiracetam polypharmacy, based on evidence-based clinical and laboratory data was of interest that investigated. Case Presentation Two cases were studied, one patient was a 32-year-old male and the other was a 14-year-old female. The key words relevant to search topics were surveyed using PubMed (United States national library of medicine. Articles related to the levetiracetam prescription in epileptic patients were selected and considered separately. Pharmacotherapy based on levetiracetam, primidone, phenytoin, and topiramate in a 32-year-old epileptic male showed a decrease in white blood cell count (3400 cells/mcL, red blood cell count (4.4 mil/mm3 hemoglobin (11.8 g/dL and hematocrit (36.7%. The drug regimen for the 14-year-old epileptic female was a levetiracetam polypharmacy in combination with primidone and sodium-valproate simultaneously. In this patient, there was a decrease in hemoglobin (10.4 g/dL and hematocrit (34%. An increase in lymphocyte (84% was also observed. Conclusions Administration of AEDs in general and levetiracetam in particular should be based on attention to pharmacokinetic behavior in terms of monotherapy or polypharmacy.

    Drug-drug interactions (DDIs) occur when the action of one drug interferes with or alters the activity of another drug taken concomitantly. This can lead to decreased drug efficacy or increased toxicity. Because of DDIs, physicians in the clinical practice attempt to avoid potential interactions when multiple drugs are coadministrated; however, there is still a large knowledge gap in understanding how drugs taken in the past can contribute to DDIs in the future. The goal of this study was to investigate the consequence of neonatal drug exposure on efficacy of other drugs administered up through adult life. We selected a mouse model to test phenobarbital exposure at a neonatal age and its impact on efficacy of omeprazole in adult life. The results of our experiment show an observed decrease in omeprazole's ability to raise gastric pH in adult mice that received single or multiple doses of phenobarbital at a neonatal age. This effect may be associated with the permanent induction of cytochrome P450 enzymes in adult liver after neonatal phenobarbital treatment. Our data indicates that DDIs may result from drugs administered in the past in an animal model and should prompt re-evaluation of how DDIs are viewed and how to avoid long-term DDIs in clinical practice.

    Disrupted sleep patterns in children with epilepsy and their parents are commonly described clinically. A number of studies have shown increased frequency of sleep disorders among pediatric epilepsy patients; however, few have characterized the association between epilepsy and parental sleep quality and household sleeping arrangements. The purpose of this study was to explore the effect of pediatric epilepsy on child sleep, parental sleep and fatigue, and parent-child sleeping arrangements, including room sharing and cosleeping. Parents of children 2 to 10 years of age with and without epilepsy completed written questionnaires assessing seizure history, child and parent sleep, and household sleeping arrangements. Children's Sleep Habits Questionnaire (CSHQ) scores were used to evaluate sleep disturbances for the child. The Pittsburgh Sleep Quality Index (PSQI) and the Iowa Fatigue Scale (IFS) were used to evaluate parental sleep and fatigue, respectively. The Early Childhood Epilepsy Severity Scale (E-Chess) was used to assess epilepsy severity. One hundred five households with a child with epilepsy and 79 controls participated in this study. Households with a child with epilepsy reported increased rates of both parent-child room sharing (p Children with epilepsy were found to have greater sleep disturbance by total CSHQ score (p Parents of children with epilepsy had increased sleep dysfunction (p = 0.005) and were more fatigued (p parental sleep dysfunction (0.273, p = 0.005), and parental fatigue (0.324, p = 0.001). Antiepileptic drug polytherapy was predictive of greater childhood sleep disturbances. Nocturnal seizures were associated with parental sleep problems, whereas room sharing and cosleeping behavior were associated with child sleep problems. Within the epilepsy cohort, 69% of parents felt concerned about night seizures and 44% reported feeling rested rarely or never. Finally, 62% of parents described decreased sleep quality and/or quantity with

    The goal of this study was to evaluate how epilepsy affected the health-related quality of life (HRQOL) in children with epilepsy, as well as the risk factors for poor HRQOL. Parents of epileptic children (n = 223) and parents of healthy children (n = 216) were enrolled. The Child Epilepsy Questionnaire-Parental form was given to all parents. Children with epilepsy had significantly lower HRQOL scores for overall QOL and all subscales. Seizure types were not associated with HRQOL, but the age of the child with epilepsy, disease courses and seizure frequency did influence the quality of life. Epilepsy has a severe impact on children's HRQOL, and age, increased seizure frequency and longer duration of epilepsy are associated with poor HRQOL. © The Author(s) 2015.

    To examine the risk of obstructive sleep apnea (OSA) in children with cerebral palsy (CP) and/or epilepsy. This cross-sectional study employs the Pediatric Sleep Questionnaire (PSQ), the Gross Motor Function Classification System (GMFCS), and chart review to identify symptoms of OSA in children presenting to a multi-specialty pediatric healthcare institution. Two-hundred and fifteen patients were grouped into those with epilepsy (n=54), CP (n=18), both (n=55), and neither (comparison group, n=88). The comparison group comprised children with developmental disabilities but not children with typical development. Significantly increased PSQ scores (indicating increased risk of OSA) were found among children with CP (58%) and CP with epilepsy (67%) than among the comparison group (27%; pChildren with both CP and epilepsy had a greater number of increased PSQ scores compared with CP alone (pchildren at risk of OSA (46%) than did the medical record review for symptoms of OSA (8.2%, pChildren with CP of greater severity or comorbid epilepsy are at increased risk of OSA.

    Epilepsy is a common serious neurologic disorder in children. However, most studies of children's functional difficulties and school limitations have used samples from tertiary care or other clinical settings. To compare functional difficulties and school limitations of a national sample of US children with special health care needs (CSHCN) with and without epilepsy. Data from the 2009-2010 National Survey of CSHCN for 31,897 children aged 6-17 years with and without epilepsy were analyzed for CSHCN in two groups: 1) CSHCN with selected comorbid conditions (intellectual disability, cerebral palsy, autism, or traumatic brain injury) and 2) CSHCN without these conditions. Functional difficulties and school limitations, adjusted for the effect of sociodemographic characteristics, were examined by epilepsy and comorbid conditions. Three percent of CSHCN had epilepsy. Among CSHCN with epilepsy 53% had comorbid conditions. Overall CSHCN with epilepsy, both with and without comorbid conditions, had more functional difficulties than CSHCN without epilepsy. For example, after adjustment for sociodemographic characteristics a higher percentage of children with epilepsy, compared to children without epilepsy, had difficulty with communication (with conditions: 53% vs. 37%, without conditions: 13% vs. 5%). Results for school limitations were similar. After adjustment, a higher percentage of children with epilepsy, compared to children without epilepsy, missed 11 + school days in the past year (with conditions: 36% vs. 18%, without conditions: 21% vs. 15%). CSHCN with epilepsy, compared to CSHCN without epilepsy, were more likely to have functional difficulties and limitations in school attendance regardless of comorbid conditions.

    Impairments in executive skills broadly span across multiple childhood epilepsy syndromes and can adversely affect quality of life. Bilingualism has been previously shown to correlate with enhanced executive functioning in healthy individuals. This study sought to determine whether the bilingual advantage in executive functioning exists in the context of pediatric epilepsy. We retrospectively analyzed neuropsychological data in 52 children with epilepsy and compared executive function scores in monolingual versus bilingual children with epilepsy while controlling for socioeconomic status and ethnicity. Bilingual children performed significantly better on the Working Memory Index than did monolingual children. There were no significant differences on the remaining executive function variables. The bilingual advantage appears to persist for working memory in children with epilepsy. These findings suggest that bilingualism is potentially a protective variable in the face of epilepsy-related working memory dysfunction. Copyright © 2015 Elsevier Inc. All rights reserved.

    Although leukotrienes have been implicated in seizures, no study has systematically investigated whether the blockade of CysLT1 receptors synergistically increases the anticonvulsant action of classic antiepileptics. In this study, behavioral and electroencephalographic methods, as well as isobolographic analysis, are used to show that the CysLT1 inverse agonist montelukast synergistically increases the anticonvulsant action of phenobarbital against pentylenetetrazole-induced seizures. Moreover, it is shown that LTD4 reverses the effect of montelukast. The experimentally derived ED50mix value for a fixed-ratio combination (1:1 proportion) of montelukast plus phenobarbital was 0.06±0.02 μmol, whereas the additively calculated ED50add value was 0.49±0.03 μmol. The calculated interaction index was 0.12, indicating a synergistic interaction. The association of montelukast significantly decreased the antiseizure ED50 for phenobarbital (0.74 and 0.04 μmol in the absence and presence of montelukast, respectively) and, consequently, phenobarbital-induced sedation at equieffective doses. The demonstration of a strong synergism between montelukast and phenobarbital is particularly relevant because both drugs are already used in the clinics, foreseeing an immediate translational application for epileptic patients who have drug-resistant seizures.

    To explore the characteristics of ecological executive function in school-aged children with idiopathic or probably symptomatic epilepsy and examine the effects of executive function on social adaptive function. A total of 51 school-aged children with idiopathic or probably symptomatic epilepsy aged 5-12 years at our hospital and 37 normal ones of the same gender, age and educational level were included. The differences in ecological executive function and social adaptive function were compared between the two groups with the Behavior Rating Inventory of Executive Function (BRIEF) and Child Adaptive Behavior Scale, the Pearson's correlation test and multiple stepwise linear regression were used to explore the impact of executive function on social adaptive function. The scores of school-aged children with idiopathic or probably symptomatic epilepsy in global executive composite (GEC), behavioral regulation index (BRI) and metacognition index (MI) of BRIEF ((62±12), (58±13) and (63±12), respectively) were significantly higher than those of the control group ((47±7), (44±6) and (48±8), respectively))(Pchildren with idiopathic or probably symptomatic epilepsy in adaptive behavior quotient (ADQ), independence, cognition, self-control ((86±22), (32±17), (49±14), (41±16), respectively) were significantly lower than those of the control group ((120±12), (59±14), (59±7) and (68±10), respectively))(Pchildren with idiopathic or probably symptomatic epilepsy. School-aged children with idiopathic or probably symptomatic epilepsy may have significantly ecological executive function impairment and social adaptive function reduction. The aspects of BRI, inhibition and working memory in ecological executive function are significantly related with social adaptive function in school-aged children with epilepsy.

    In response to criticism that epilepsy care for children has little impact, healthcare professionals and administrators have developed various service models and strategies to address perceived inadequacies. To assess the effects of any specialised or dedicated intervention for epilepsy versus usual care in children with epilepsy and in their families. We searched the Cochrane Epilepsy Group Specialized Register (27 September 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 9) in the Cochrane Library, MEDLINE (1946 to 27 September 2016), Embase (1974 to 27 September 2016), PsycINFO (1887 to 27 September 2016) and CINAHL Plus (1937 to 27 September 2016). In addition, we also searched clinical trials registries for ongoing or recently completed trials, contacted experts in the field to seek information on unpublished and ongoing studies, checked the websites of epilepsy organisations and checked the reference lists of included studies. We included randomised controlled trials (RCTs), cohort studies or other prospective studies with a (matched or unmatched) control group (controlled before-and-after studies), or time series studies. We used standard methodological procedures expected by Cochrane. Our review included six interventions reported through seven studies (of which five studies were designed as RCTs). They reported on different education and counselling programmes for children and parents; teenagers and parents; or children, adolescents and their parents. Each programme showed some benefits for the well-being of children with epilepsy, but all had methodological flaws (e.g. in one of the studies designed as an RCT, randomisation failed), no single programme was independently evaluated with different study samples and no interventions were sufficiently homogeneous enough to be included in a meta-analysis,. While each of the programmes in this review showed some benefit to children with epilepsy, their impacts were extremely

    Children and youth with epilepsy have long been subjected to excessive restrictions on extracurricular activities due to concerns over risk of injury. Over time physicians and medical regulatory associations have liberalized the advice given for people with epilepsy to promote independence, self-esteem and general health benefits of physical activity. Current evidence suggests that few restrictions are needed for children with epilepsy beyond water-related precautions and avoidance of very high-risk activities. However, more stringent restrictions on daily activities may be imposed by caregivers. This study was aimed at exploring current perceptions of parents regarding restrictions on activity for children with epilepsy and the child's perspective on restrictions related to the diagnosis. A self-administered questionnaire was offered to a sample of parent-child dyads of children/youth with epilepsy attending summer camp for children with epilepsy age 8-18years. A 10-item validated HARCES Parent Scale of Childhood Epilepsy was completed by the parent/guardian and a modified-HARCES completed by the child. The primary objective was to assess the degree of restrictions placed on children with epilepsy from the perspective of child and parent assessed independently. Agreement of perceived restrictions between parent-child dyads was also determined. 21 parent/guardian-child pairs were recruited with mean age of children/youth 12.7years (range 9-16years). Total HARCES scores for parents and guardians ranged from 11-26 (x=16.5; SD 4.9) while total scores for children with epilepsy similarly ranged from 10-25 (x=15.2; SD 4.9). There were no differences in total parent scores when analyzed by child's age (13years), gender, age of seizure onset, seizure frequency or seizure type. Total HARCES scores showed no agreement between parent and child pairs with correlation of 0.2798 (95% CI -0.173-0.635). Children and youth with epilepsy often face activity restrictions based on

    This study compared the relationship of language skill with fronto-temporal volumes in 69 medically treated epilepsy subjects and 34 healthy children, aged 6.1-16.6 years. It also determined if the patients with linguistic deficits had abnormal volumes and atypical associations between volumes and language skills in these brain regions. The children underwent language testing and magnetic resonance imaging scans at 1.5 Tesla. Brain tissue was segmented and fronto-temporal volumes were computed. Higher mean language scores were significantly associated with larger inferior frontal gyrus, temporal lobe, and posterior superior temporal gyrus gray matter volumes in the epilepsy group and in the children with epilepsy with average language scores. Increased total brain and dorsolateral prefrontal gray and white matter volumes, however, were associated with higher language scores in the healthy controls. Within the epilepsy group, linguistic deficits were related to smaller anterior superior temporal gyrus gray matter volumes and a negative association between language scores and dorsolateral prefrontal gray matter volumes. These findings demonstrate abnormal development of language related brain regions, and imply differential reorganization of brain regions subserving language in children with epilepsy with normal linguistic skills and in those with impaired language.

    Our objective was to examine the relationships of factors associated with children's emotional well-being 2 years after diagnosis, and to examine if these relationships are mediated or moderated by family factors. Data came from a multicenter prospective cohort study of children with newly diagnosed epilepsy from across Canada (Health-Related Quality of Life in Children with Epilepsy Study; HERQULES, n = 373). Emotional well-being was assessed using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55). The relationships between clinical factors, family factors, and emotional well-being were assessed using multiple regression analyses. Family functioning, family stress, and repertoire of resources that the families had to adapt to stressful events were significantly associated with poor emotional well-being 2 years after diagnosis (p < 0.05) in the multivariable analysis. The effect of parental depressive symptoms was partially mediated by family functioning and family stress (p < 0.01 and p = 0.02, respectively). Family resources acted as a moderator in the relationship between severity of epilepsy and emotional well-being (p < 0.05). Based on our findings, efforts to strengthen the family environment may warrant attention. We suggest that clinicians take a family centered care approach by including families in treatment planning. Family centered care has been shown to improve family well-being and coping and in turn may reduce the impact of clinical factors on emotional well-being to improve long-term health-related quality of life.

    In a previous study we reported difficulty with expressive language and visuoperceptual ability in preschool children with epilepsy and otherwise normal development. The present study analysed speech and language dysfunction for each individual in relation to epilepsy variables, ear preference, and intelligence in these children and described their auditory function. Twenty 6-year-old children with epilepsy (14 females, 6 males; mean age 6:5 y, range 6 y-6 y 11 mo) and 30 reference children without epilepsy (18 females, 12 males; mean age 6:5 y, range 6 y-6 y 11 mo) were assessed for language and auditory ability. Low scores for the children with epilepsy were analysed with respect to speech-language domains, type of epilepsy, site of epileptiform activity, intelligence, and language laterality. Auditory attention, perception, discrimination, and ear preference were measured with a dichotic listening test, and group comparisons were performed. Children with left-sided partial epilepsy had extensive language dysfunction. Most children with partial epilepsy had phonological dysfunction. Language dysfunction was also found in children with generalized and unclassified epilepsies. The children with epilepsy performed significantly worse than the reference children in auditory attention, perception of vowels and discrimination of consonants for the right ear and had more left ear advantage for vowels, indicating undeveloped language laterality.

    More than 25 % of children with epilepsy develop refractory seizures unresponsive to both old and new generation anticonvulsants. Since such seizures have a serious negative impact on the quality of life, other treatment options are considered. The ketogenic diet is a well-known treatment for managing refractory seizures, although its mechanism of action is unknown. Studies have shown that this diet is as good as, or better than, any of the newer medications in reducing seizure frequency. However, concerns about adverse effects have been raised. We conducted an open label trial to show the effects of this diet on serum lipid profile. Thirty-three children with refractory epilepsy were treated with the ketogenic diet and were followed for 6 months. Their serum lipid profile was assessed at baseline, and at 3 and 6 months after initiating the diet. Seizure frequency was reduced in 63 % of children (no seizures in 2/33 and reduced >50 % in 19/33). However, after 6 months of administering the diet, median triglyceride was significantly increased (from 84 to 180 mg/dl, P ketogenic diet in children with refractory seizures is effective in seizure reduction, but leads to development of hypercholesterolemia and hypertriglyceridemia.

    To assess prevalence of behavioral problems in children with epilepsy. This was a cross-sectional study of children with epilepsy, and normal controls enrolled between July 2013 to June 2015. Child Behavior Checklist (CBCL) was used as a tool to assess the behavior based on parents reported observation. There were 60 children with epilepsy in 2-5 years and 80 in 6-14 years age groups, and 74 and 83 unaffected controls, respectively. Mean CBCL scores for most of the domains in children of both age groups were significantly higher than controls. Clinical range abnormalities were mainly detected in externalizing domain (23.3%) in 2-5 years, and in both internalizing (21.2%) and externalizing (45%) domains in children of 6-14 years. Younger age of onset, frequency of seizures and duration of disease had significant correlation with behavioral problems in both the age groups. Antiepileptic drug polytherapy was significantly associated with internalizing problems in older children. Age at onset, frequency of seizures and duration of disease were found to be significantly associated with occurrence of behavioral problems.

    Birth weight is an important indicator of prenatal/in-utero environment. Variations in birth weight have been reportedly associated with risks for cognitive problems. The National Longitudinal Survey of Children and Youth (NLSCY) dataset was explored to examine relationships between birth weight, academic school readiness and epilepsy. A population based sample of 32,900 children of the NLSCY were analyzed to examine associations between birth weight, and school readiness scores in 4-5-year-old children. Logistic and Linear regression was used to examine associations between having epilepsy and these outcomes. Gestation data was available on 19,867 children, full-term children represented 89.67% (gestation >259days), while 10.33% of children were premature (gestation children with reported epilepsy in the sample. Effects of confounding variables (diabetes in pregnancy, smoking in pregnancy, high blood pressure during pregnancy, and gender of the infant) on birth weight and epilepsy were controlled using a separate structural equation model. Logistic regression analysis identified an association between epilepsy and lower birth weights, as well as an association between lower birth weight, having epilepsy and lower PPVT-R Scores. Model results show the relationship between low birth weight and epilepsy remains statistically significant even when controlling for the influence of afore mentioned confounding variables. Low birth weight appears to be associated with both epilepsy and academic school readiness. The data suggest that an abnormal prenatal environment can influence both childhood onset of epilepsy and cognition. Additional studies with larger sample sizes are needed to verify this relationship in detail. Copyright © 2017 Elsevier B.V. All rights reserved.

    Epilepsy is common in sub-Saharan Africa (SSA), but the clinical features and consequences are poorly characterized. Most studies are hospital-based, and few studies have compared different ecological sites in SSA. We described active convulsive epilepsy (ACE) identified in cross-sectional community-based surveys in SSA, to understand the proximate causes, features, and consequences. We performed a detailed clinical and neurophysiologic description of ACE cases identified from a community survey of 584,586 people using medical history, neurologic examination, and electroencephalography (EEG) data from five sites in Africa: South Africa; Tanzania; Uganda; Kenya; and Ghana. The cases were examined by clinicians to discover risk factors, clinical features, and consequences of epilepsy. We used logistic regression to determine the epilepsy factors associated with medical comorbidities. Half (51%) of the 2,170 people with ACE were children and 69% of seizures began in childhood. Focal features (EEG, seizure types, and neurologic deficits) were present in 58% of ACE cases, and these varied significantly with site. Status epilepticus occurred in 25% of people with ACE. Only 36% received antiepileptic drugs (phenobarbital was the most common drug [95%]), and the proportion varied significantly with the site. Proximate causes of ACE were adverse perinatal events (11%) for onset of seizures before 18 years; and acute encephalopathy (10%) and head injury prior to seizure onset (3%). Important comorbidities were malnutrition (15%), cognitive impairment (23%), and neurologic deficits (15%). The consequences of ACE were burns (16%), head injuries (postseizure) (1%), lack of education (43%), and being unmarried (67%) or unemployed (57%) in adults, all significantly more common than in those without epilepsy. There were significant differences in the comorbidities across sites. Focal features are common in ACE, suggesting identifiable and preventable causes. Malnutrition and

    To determine the effectiveness of epilepsy self-management interventions and explore the views and experiences of medication and seizures by children and young people. Experiencing seizures and side-effects from anti-epileptic medicines have negative impacts on children and young people managing their epilepsy. Children commonly experiment with not taking epilepsy medication as prescribed and engage in unhealthy lifestyles. DESIGN/REVIEW METHODS: Mixed-method systematic review with theory development. Cochrane quantitative methods and thematic synthesis of qualitative and survey evidence. Eight databases were searched from earliest dates to July 2013. Nineteen studies were included. Meta-analysis was not possible. Zero of nine intervention studies showed improvement in anti-epilepsy medication adherence. Skill-based behavioural techniques with activities such as role play and goal setting with young people increased epilepsy knowledge and seizure self-management (small effects). Intervention studies were methodologically weak and no studies reported if improvement in self-management was sustained over time. Synthesis of nine qualitative and one mixed-method studies generated six themes encapsulating anti-epilepsy medication and epilepsy effects. There was a lack of fidelity between intervention programme theories and what children and young people found difficult with medication self-management and managing the effects of epilepsy. Children and young people knowingly and/or unknowingly take risks with their epilepsy and give reasoned explanations for doing so. There are no effective interventions to change epilepsy medication adherence behaviours. There is an urgent need for more innovative and individually tailored interventions to address specific challenges to epilepsy self-management as identified by children and young people themselves. © 2014 John Wiley & Sons Ltd.

    Oral cannabis extracts (OCEs) are being used in the treatment of epilepsy with increasing rates in the United States following product legalization; however, no studies demonstrate clear efficacy. We evaluated the duration of use of OCEs as a measure of perceived benefit in a cohort of patients with pediatric epilepsy. Retrospective chart review was performed of children and adolescents who were given OCEs for treatment of epilepsy. Of the 119 patients included in the analysis, 71% terminated use of their OCE product during the study period. The average length of use of OCE was 11.7 months (range 0.3-57 months). Perceived seizure benefit was the only factor associated with longer duration of treatment with OCE (p 50% reduction in seizures while on this therapy. Adverse events (AEs) were reported in 19% of patients, with the most common side effects being somnolence and worsening of seizures. Parental report of OCE use in refractory pediatric epilepsy suggests that some families perceive benefit from this therapy; however, discontinuation of these products is common. Duration appears to be affected by logical factors, such as perceived benefit and side effect profile. Surprisingly, families of patients with Dravet syndrome terminated use of OCEs more quickly than patients with other epilepsy syndromes. Results from this study highlight the need for rigorous clinical studies to characterize the efficacy and safety of OCEs, which can inform discussions with patients and families.

    The objective of this study was to evaluate the efficacy of Modular Education Program for Children with Epilepsy and Their Parents on disease management. The program was prepared by researchers in an interdisciplinary team. Children with epilepsy and their parents were included in a randomized controlled study using a pre-posttest design. All participants of the modular education program (n=184 (92 children and their 92 parents')) answered a lot of scales immediately before the program. The researcher presented the modular education program, which included eight modules (four for the children and four for the parents), to the children and parents in the intervention group using interactive teaching methods. And all participants of the modular education program answered all scales immediately after the program and one-month, three-month follow-ups. The control group not participating in the modular education program (n=100 (50 children, 50 parents)) also answered all scales in all follow-ups. Scales used the study comprised epilepsy-specific outcome measures (e.g., knowledge, self-efficacy related to seizures, quality of life and anxiety). The statistical analyses of the study data were performed using SAS 9.3 software. Children in intervention group significantly improved in knowledge (pepilepsy (pChildren with Epilepsy and Their Parents on disease management was confirmed. The results indicate that using interactive teaching methods help children with epilepsy and their parents in improving knowledge, self-efficacy about seizures and quality of life.

    Results are described of a preliminary study of the effects of phenytoin, (commonly used as an anticonvulsant in the treatment of patients with brain tumours), on the plasma pharmacokinetics of misonidazole (MISO) in man. Previous studies have shown that pretreatment with phenytoin shortens the half-life of MISO in dogs and mice by induction of drug metabolizing enzymes, and also reduces the acute lethal effects of MISO in mice. In this study patients with various types of malignancy and with cerebral metastases were given MISO before and after a course of phenytoin. Others were assessed as controls without phenytoin administration. Plasma concentrations of MISO were determined in blood samples taken before and at various times after administration. A summary of the pharmacokinetic data obtained is given. (author)

    Full Text Available Cognitive and mental disorders often occur in patients with epilepsy and significantly reduce the quality of life of patients and their families. Approximately in 35 % of patients, despite treatment, various violations of intelligence, behavior, affective sphere of different degree of seve rity are preserved. In general, mental (affective, anxious and psychotic disorders occur in epilepsy 2–3 times more often than in the general population. The most common is depression: the occurrence of depression and anxiety in epilepsy varies from 20 to 55 % (and more than 50 % of patients with refractory focal epilepsy, especially epilepsy of the temporal lobe of the brain. Children are a particularly vulnerable category of patients: in addition to persistent intellectual disabilities (mental retardation, they may have specific impairments in the form of mental and speech development delay, learning difficulties, attention deficit hyperactivity disorder.Causes of cognitive and mental disorders in epilepsy can directly be the factor underlying epilepsy (genetic disease, structural brain defect, etc., epileptic seizures, interictal epileptiform activity, side effects of antiepileptic drugs (AED. In many cases, a patient with epilepsy combines several of these causes, and it is often difficult to determine which one cause is leading. The contribution of specific factors is difficult to estimate, because different factors can have an independent different effect on cognitive impairment. Some of causes underlying cognitive and mental disorders in epilepsy can be influenced and thus reduce the existing risk. Such measures include early diagnosis and effective adequate treatment of epileptic encephalopathy, as early as possible control of seizures, justified appointment of AED in children with cognitive impairment of unknown etiology and frequent epileptiform discharges on the electroencephalogram, careful monitoring of cognitive side effects of AED and

    The effects of epilepsy may disturb the ability of the child and family to function and has detrimental effects on health-related quality of life (HRQOL). We determined HRQOL and related factors in children and adolescents with epilepsy in Iran. This cross-sectional study was performed in a private neurology pediatric clinic in Guilan Province (North of Iran). We evaluated 108 children and adolescents with epilepsy. Data were collected by interview with parents and review of medical records. Generic and specific HRQOL was evaluated by Child Health Questionnaire and QOL in Childhood Epilepsy Questionnaire, respectively. The mean of overall generic HRQOL score was 71.05 ± 11.31. The lowest score was related to parental impact: emotional (52.59 ± 15.49). The average total specific HRQOL score was 71.95 ± 11.16. The lowest score dedicated to general health (51.21 ± 18.25). In multivariate regression analysis, duration of epilepsy (p epilepsy (p epilepsy (p epilepsy duration was the strongest predictor of both generic and specific HRQOL in children and adolescents with epilepsy. This will be useful for clinicians in epilepsy management, which will enhance HRQOL.

    Against a backdrop of recommendations for increasing access to and uptake of early surgical intervention for children with medically intractable epilepsy, it is important to understand how parents and professionals decide to put children forward for epilepsy surgery and what their decisional support needs are. The aim of this study was to explore how parents and health professionals make decisions regarding putting children forward for pediatric epilepsy surgery. Individual interviews were conducted with nine parents of children who had undergone pediatric epilepsy surgery at a specialist children's hospital and ten healthcare professionals who made up the children's epilepsy surgery service multidisciplinary healthcare team (MDT). Three MDT meetings were also observed. Data were analyzed thematically. Four themes were generated from analysis of interviews with parents: presentation of surgery as a treatment option, decision-making, looking back, and interventions. Three themes were generated from analysis of interviews/observations with health professionals: triangulating information, team working, and patient and family perspectives. Parents wanted more information and support in deciding to put their child forward for epilepsy surgery. They attempted to balance the potential benefits of surgery against any risks of harm. For health professionals, a multidisciplinary approach was seen as crucial to the decision-making process. Advocating for the family was perceived to be the responsibility of nonmedical professionals. Decision-making can be supported by incorporating families into discussions regarding epilepsy surgery as a potential treatment option earlier in the process and by providing families with additional information and access to other parents with similar experiences.

    This study aimed to evaluate a microemulsion system (ME) containing phenobarbital in epilepsy model induced by pilocarpine in rats and to oxidative stress and histologic lesions in hippocampus. The microemulsion was applied to the shaved back of Wistar rats. The animals were divided into the following groups: control group (P400); ME50 40mg/kg, topically-t.p.; ME100, 40mg/kg, t.p.; EM50, 40mg/kg, t.p.; phenobarbital solution 40mg/kg (PS), oral. After 60min, behavioral changes were evaluated for 1h in the model of epileptical crisis induced by pilocarpine. Phenobarbital in microemulsion was able to increase the latency for status epilepticus (SE) (p<0.05), decrease the number of epileptical crisis (ME50: p<0.001; ME100: p<0.01) and decrease mortality rate by 80% compared to P400. In EM50 and PS groups, deaths were decreased by 53.3% and 100% respectively. The ME50 and ME100 groups were able to reduce oxidative stress in experimental animals when compared to the P400. The microemulsion was still capable of reducing neuronal damage in the hippocampal areas. The results of this study come in an innovative way, demonstrating the ability of transdermal ME50 and ME100 to reduce pilocarpine-induced epileptical crisis, oxidative stress, besides neuronal damages.

    The objective of this study was to examine the association between convulsive status epilepticus (CSE) and health-related quality of life (HRQL) during a 24-month follow-up in a multisite incident cohort of children with epilepsy. Data were collected in the Health-Related Quality of Life Study in Children with Epilepsy Study from 374 families of children with newly diagnosed epilepsy. The Quality of Life in Childhood Epilepsy (QOLCE) Questionnaire was used to evaluate parent-reported child HRQL. Hierarchical linear regression was used to examine the relationship between CSE and HRQL at 24 months postepilepsy. A total of 359 families completed the 24-month assessment. Twenty-two children (6.1%) had experienced CSE during the follow-up. Children with and without CSE were similar, except a larger proportion of children with CSE had partial seizures (p QOLCE scores. The findings suggested that not only do children with CSE have significantly poorer HRQL compared with their non-CSE counterparts, but that this factor is independent of the effects of demographic and clinical features known to affect HRQL. © 2014 American Academy of Neurology.

    Full Text Available Structured online surveys were used to explore the experiences of the parents of children with refractory epilepsy using medicinal cannabis in Mexico during September 2016. The surveys, which were completed in full, were reviewed, and 53 cases of children aged between 9 months and 18 years were identified. Of these, 43 cases (82% were from Mexico and 10 (18% were from Latin American countries. Of the 43 Mexican cases, the diagnoses were as follows: 20 cases (47% had Lennox-Gastaut syndrome (LGS; 13 cases (30% had unspecified refractory epilepsy (URE; 8 cases (19% had West syndrome (WS; 1 case (2% had Doose syndrome (DS; and 1 case (2% had Ohtahara syndrome (OS. In total, 47.1% of cases had previously been treated with 9 or more anticonvulsant therapies. The parents reported a decrease in convulsions when cannabidiol was used in 81.3% of the cases; a moderate to significant decrease occurred in 51% of cases, and 16% of cases were free from seizure. The number of antiepileptic drugs being used was reduced in 9/43 (20.9% cases. No serious adverse effects were reported, with only some mild adverse effects, such as increased appetite or changes in sleep patterns, reported in 42% of cases.

    To determine correlations of the EEG frequency spectrum with neuropsychological status in children with idiopathic epilepsy. Forty-six children ages 8-18 years old with idiopathic epilepsy were retrospectively identified and analyzed for correlations between EEG spectra and neuropsychological status using multivariate linear regression. In addition, the theta/beta ratio, which has been suggested as a clinically useful EEG marker of attention-deficit hyperactivity disorder (ADHD), and an EEG spike count were calculated for each subject. Neuropsychological status was highly correlated with posterior alpha (8-15 Hz) EEG activity in a complex way, with both positive and negative correlations at lower and higher alpha frequency sub-bands for each cognitive task in a pattern that depends on the specific cognitive task. In addition, the theta/beta ratio was a specific but insensitive indicator of ADHD status in children with epilepsy; most children both with and without epilepsy have normal theta/beta ratios. The spike count showed no correlations with neuropsychological status. (1) The alpha rhythm may have at least two sub-bands which serve different purposes. (2) The theta/beta ratio is not a sensitive indicator of ADHD status in children with epilepsy. (3) The EEG frequency spectrum correlates more robustly with neuropsychological status than spike count analysis in children with idiopathic epilepsy. (1) The role of posterior alpha rhythms in cognition is complex and can be overlooked if EEG spectral resolution is too coarse or if neuropsychological status is assessed too narrowly. (2) ADHD in children with idiopathic epilepsy may involve different mechanisms from those in children without epilepsy. (3) Reliable correlations with neuropsychological status require longer EEG samples when using spike count analysis than when using frequency spectra.

    SUMMARY Objective Deficits in executive function are increasingly noted in children with epilepsy and have been associated with poor academic and psychosocial outcomes. Impaired inhibitory control contributes to executive dysfunction in children with epilepsy; however, its neuroanatomic basis has not yet been investigated. We used functional Magnetic Resonance Imaging (fMRI) to probe the integrity of activation in brain regions underlying inhibitory control in children with epilepsy. Methods This cross-sectional study consisted of 34 children aged 8 to 17 years: 17 with well-controlled epilepsy and 17 age-and sex-matched controls. Participants performed the antisaccade (AS) task, representative of inhibitory control, during fMRI scanning. We compared AS performance during neutral and reward task conditions and evaluated task-related blood-oxygen level dependent (BOLD) activation. Results Children with epilepsy demonstrated impaired AS performance compared to controls during both neutral (non-reward) and reward trials, but exhibited significant task improvement during reward trials. Post-hoc analysis revealed that younger patients made more errors than older patients and all controls. fMRI results showed preserved activation in task-relevant regions in patients and controls, with the exception of increased activation in the left posterior cingulate gyrus in patients specifically with generalized epilepsy across neutral and reward trials. Significance Despite impaired inhibitory control, children with epilepsy accessed typical neural pathways as did their peers without epilepsy. Children with epilepsy showed improved behavioral performance in response to the reward condition, suggesting potential benefits of the use of incentives in cognitive remediation. PMID:25223606

    Diagnosis of epilepsy is known to impact health-related quality of life (HRQOL) of children with new-onset epilepsy and can also influence their conceptualization and valuation of HRQOL construct, also known as response shift. This study investigates the presence of response shift in a cohort of children with new-onset epilepsy. Data are from the HEalth-Related QUality of Life in children with Epilepsy Study, a prospective cohort study of 373 children with new-onset epilepsy. Hypotheses about the presence of reconceptualization, reprioritization, and recalibration response shift were tested in the Quality of Life in Childhood Epilepsy (QOLCE-55) Questionnaire, a parent-reported, disease-specific HRQOL measure, using Oort's structural equation model between baseline and 1-year follow-up. Model fit was assessed using log-likelihood ratio test, root mean square error of approximation, and comparative fit index. Small positive uniform recalibration response shift effects were observed on physical, emotional, and social functioning domains of the QOLCE-55, but negligibly small negative nonuniform recalibration response shift effect was observed on social functioning domain. There was no significant change in overall QOLCE-55 scores over time after adjusting for response shift effects. Parents of children with new-onset epilepsy are likely to positively recalibrate (upward bias) their assessments of their children's HRQOL over a 1-year period after diagnosis. This study highlights the potential benefits of response shift as a desired consequence in parents' perception of changes in HRQOL of children with new-onset epilepsy. Copyright © 2017 Elsevier Inc.

    Full Text Available In children with temporal lobe epilepsy (TLE, memory deficit is not so well understood as it is in adults. The aim of this study was to identify and describe memory deficits in children with symptomatic TLE, and to verify the influence of epilepsy variables on memory. We evaluated 25 children with TLE diagnosed on clinical, EEG and MRI findings. Twenty-five normal children were compared with the patients. All children underwent a neuropsychological assessment to estimate intellectual level, attention, visual perception, handedness, and memory processes (verbal and visual: short-term memory, learning, and delayed recall. The results allowed us to conclude: besides memory deficits, other neuropsychological disturbances may be found in children with TLE such as attention, even in the absence of overall cognitive deficit; the earlier onset of epilepsy, the worse verbal stimuli storage; mesial lesions correlate with impairment in memory storage stage while neocortical temporal lesions correlate with retrieval deficits.

    Epilepsy is a chronic disorder that is associated with numerous psychological challenges, especially in children. Drawings have been underutilized as a method to obtain insight into psychological issues in children with epilepsy. We asked 105 children with epilepsy, ages 5 to 18 years, to draw a picture of what it is like to have a seizure. Across ages and epilepsy syndromes, the drawings showed evidence of impaired self-concept, low self-esteem, and a sense of helplessness and vulnerability. Overall, the drawings of human figures were less developed than expected for chronological age. In some drawings, indicators of underlying depression were found. When considered by epilepsy syndrome or seizure type, some specific artistic features were noted. Children with simple partial (motor) seizures drew distorted body parts, especially limbs. Those with complex partial seizures depicted sensory symptoms and mental status changes such as confusion. Children with generalized tonic-clonic seizures showed shaking extremities. Drawings by children with absence seizures illustrated mainly staring. In conclusion, drawings are a powerful method to examine the self-concept of children with epilepsy and gain insight into their feelings about themselves and their world.

    Persons with epilepsy need adequate advice and effective counselling about issues such as marriage, pregnancy, risks of inheriting epilepsy, driving, employment and antiepileptic drug withdrawal, because these persons are not receiving important information and education about their condition and possible adverse effects of treatment. Furthermore, women with epilepsy have increased rates of pregnancy complications and poor fetal outcomes including congenital malformations and developmental delay related to both their epilepsy and antiepileptic drugs. However, approximately 90% of all women with epilepsy undergo normal pregnancy and give birth to children free of birth defects. Pregnancy is generally safe in women with epilepsy. The study of long-term prognosis of childhood-onset epilepsy in Japan shows that the majority of these patients have lower levels of educational background as well as employment and marital status compared with the general population (Wakamoto H. et al). Of patients with epilepsy, 60% to 70% achieve control with antiepileptic medication. However, several antiepileptic drug withdrawal studies show variable rates of success, with relapse rates ranging from 12% to 63% (Britton J.W.). Driving is listed as major problem in persons with epilepsy. However, the patients with seizure-free more than two years have been able to get the driver's license since June, 2002. Social attitudes towards epilepsy cause more distress to the patient than the disease itself. We should realize that persons with epilepsy are normal or near-normal. To ameliorate the social stigma against epilepsy, continuous and repetitive educational efforts would be needed.

    Full Text Available OBJECTIVE: To verify the effectiveness of the support group in the identification of family variables linked to epilepsy. METHOD: Pre-test were applied to parents of 21 children with benign epilepsy of childhood recently diagnosed, from 5 to 15 years, who participated in the groups at HC/Unicamp. There was a presentation of an educational video, discussion and application of the post-test 1. After six months, the post-test 2 was applied. RESULTS: The beliefs were: fear of swallowing the tongue during the seizures (76.19% and of a future mental disease (66.67%. Facing the epilepsy, fear and sadness appeared. 76.19% of the parents presented overprotection and 90.48%, expected a new seizure. In the post-test 1, the parents affirmed that the information offered had modified the beliefs. In the post-test 2, 80.95% didn't report great doubts about epilepsy and 90.48% considered their relationship with their children better. CONCLUSIONS: The demystification of beliefs supplied from the groups influenced the family positively, prevented behavior alterations and guaranteed effective care in the attendance to the child with epilepsy.

    Difficulties in reading comprehension can arise from either word reading or listening comprehension difficulties, or a combination of the two. We sought to determine whether children with rolandic epilepsy had poor reading comprehension relative to typically developing comparison children, and whether such difficulties were associated with word reading and/or general language comprehension difficulties. In this cross-sectional study, children with rolandic epilepsy (n=25; 16 males, 9 females; mean age 9y 1mo, SD 1y 7mo) and a comparison group (n=39; 25 males, 14 females; mean age 9y 1mo, SD 1y 3mo) completed assessments of reading comprehension, listening comprehension, word/non-word reading, speech articulation, and Non-verbal IQ. Reading comprehension and word reading were worse in children with rolandic epilepsy (F 1,61 =6.89, p=0.011, ηp2=0.10 and F 1,61 =6.84, p=0.011, ηp2=0.10 respectively), with listening comprehension being marginal (F 1,61 =3.81, p=0.055, ηp2=0.06). Word reading and listening comprehension made large and independent contributions to reading comprehension, explaining 70% of the variance. Children with rolandic epilepsy may be at risk of reading comprehension difficulties. Thorough assessment of individual children is required to ascertain whether the difficulties lie with decoding text, or with general comprehension skills, or both. Children with rolandic epilepsy may be at risk of poor reading comprehension. This was related to poor word reading, poor listening comprehension, or both. Reading comprehension interventions should be tailored to the profile of difficulties. © 2017 Mac Keith Press.

    To explore the influence of several estimates of family socioeconomic status on the long-term clinical course and social outcomes of children with epilepsy. The Nova Scotia childhood epilepsy cohort is population based and includes all children in this Canadian province who developed epilepsy between 1977 and 1985. Eligible patients had ≥10 years of follow-up. Children with childhood absence epilepsy were excluded. Total family income at seizure onset was assessed at seizure onset and classified as "poor" (first quintile), "adequate" (second to third quintiles), and "well-off" (fourth to fifth quintiles). We also assessed parental education and home ownership. Social outcome was assessed in those with normal intelligence who were ≥18 years of age at the end of follow-up using a semistructured interview that explored eight adverse effects. Of 584 patients, 421 (72%) were included. Average follow-up was 26 ± 5.6 years. Overall 137 families (33%) had "poor" income, 159 (38%) had "adequate income," and 125 (30%) were "well-off." Terminal remission of epilepsy occurred in 65% of the poor, 61% of the adequate, and 61% of the well-off (p = ns). Intractable epilepsy, status epilepticus, number of antiepileptic drugs (AEDs) used, and the number of generalized tonic-clonic or focal with secondary generalization seizures through the clinical course was the same in all groups. Home ownership did not predict remission. Neither paternal nor maternal education was associated with remission. Poor children had significantly more adverse social outcomes including failure to graduate from high school, unemployment, personal poverty, inadvertent pregnancy, and psychiatric diagnoses. In Nova Scotia with universal health care, coming from a poor or more affluent family does not seem to affect the clinical course or long-term seizure outcome of childhood epilepsy. Unfortunately children from poor families are less likely to have a good social outcome. Wiley Periodicals, Inc

    physicians, 84% of mothers had provided their children with at least one ineffective treatment, mostly based on superstitions. Mothers' level of knowledge of epilepsy was good, and their attitudes towards epilepsy were mainly positive. Regarding the right first-aid measures at time of the last seizure, mothers' practices were acceptable. However, there is still room for improvement regarding avoiding the wrong measures. It is suggested that both practice-related issues and other aspects of epilepsy be taken into account in epilepsy-related education programs. Copyright © 2016 Elsevier Inc. All rights reserved.

    Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

    To determine whether refractory epilepsy affects the health-related quality of life (HRQOL) of children with or without intellectual disability (ID), and if the presence of ID independently compromises HRQOL in children with refractory epilepsy. Subjects were parents of children with refractory epilepsy, whose syndrome had been defined using ILAE (International League Against Epilepsy) criteria and video-EEG monitoring. Children had the presence or absence of ID determined by formal neuropsychological or educational assessment. The relative effect of epilepsy on the two intellectual ability groups was determined using relevant clinical variables. Parents completed a valid epilepsy-specific HRQOL questionnaire for children, the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE), and, depending on intellectual ability level, the Child Behaviour Checklist or Developmental Behaviour Checklist. Both intellectually normal children with epilepsy and children with epilepsy and ID were more likely to have psychosocial problems compared with their respective intellectual ability reference populations. The results also revealed that children with ID had reduced HRQOL compared with intellectually normal children; a result independent of epilepsy. Analysis of the relationship between epilepsy variables and HRQOL revealed that the QOLCE was the most sensitive in detecting variation in age at onset, seizure frequency, and medications taken. The HRQOL of children with refractory epilepsy is greatly affected, regardless of intellectual ability level. The presence of ID in children with epilepsy independently depresses HRQOL outcomes. Compared with two generic HRQOL measures, the QOLCE was the most sensitive measure to variation in epilepsy variables.

    Full Text Available Animal studies and preliminary clinical trials have shown that cannabidiol-enriched extracts may have beneficial effects for children with treatment-resistant epilepsy. However, these compounds are not yet registered as medicines by regulatory agencies. We describe the cases of two children with treatment-resistant epilepsy (Case A with left frontal dysplasia and Case B with Dravet Syndrome with initial symptom improvement after the introduction of CBD extracts followed by seizure worsening after a short time. The children presented typical signs of intoxication by ∆9-THC (inappropriate laughter, ataxia, reduced attention, and eye redness after using a cannabidiol-enriched extract. The extract was replaced by the same dose of purified cannabidiol with no ∆9-THC in both cases, which led to improvement in intoxication signs and seizure remission. These cases support pre-clinical and preliminary clinical evidence suggesting that cannabidiol may be effective for some patients with epilepsy. Moreover, the cases highlight the need for randomized clinical trials using high-quality and reliable substances to ascertain the safety and efficacy of cannabinoids as medicines.

    Neurosurgical treatment may improve seizures in children and adolescents with drug-resistant epilepsy, but additional data are needed from randomized trials. In this single-center trial, we randomly assigned 116 patients who were 18 years of age or younger with drug-resistant epilepsy to undergo brain surgery appropriate to the underlying cause of epilepsy along with appropriate medical therapy (surgery group, 57 patients) or to receive medical therapy alone (medical-therapy group, 59 patients). The patients in the medical-therapy group were assigned to a waiting list for surgery. The primary outcome was freedom from seizures at 12 months. Secondary outcomes were the score on the Hague Seizure Severity scale, the Binet-Kamat intelligence quotient, the social quotient on the Vineland Social Maturity Scale, and scores on the Child Behavior Checklist and the Pediatric Quality of Life Inventory. At 12 months, freedom from seizures occurred in 44 patients (77%) in the surgery group and in 4 (7%) in the medical-therapy group (Pchildren and adolescents with drug-resistant epilepsy who had undergone epilepsy surgery had a significantly higher rate of freedom from seizures and better scores with respect to behavior and quality of life than did those who continued medical therapy alone at 12 months. Surgery resulted in anticipated neurologic deficits related to the region of brain resection.

    Smit, Elisa; Odd, David; Whitelaw, Andrew

    2013-08-13

    Intraventricular haemorrhage (IVH) is a major complication of preterm birth. Large haemorrhages are associated with a high risk of disability and hydrocephalus. Instability of blood pressure and cerebral blood flow are postulated as causative factors. Another mechanism may involve reperfusion damage from oxygen free radicals. Phenobarbital has been suggested as a safe treatment that stabilises blood pressure and may protect against free radicals. To determine the effect of postnatal administration of phenobarbital on the risk of IVH, neurodevelopmental impairment or death in preterm infants. We used the search strategy of the Neonatal Collaborative Review Group. The original review author (A Whitelaw) was an active trialist in this area and had personal contact with many groups in this field. He handsearched journals from 1976 (when cranial computed tomography (CT) scanning started) to October 2000; these included: Pediatrics, Journal of Pediatrics, Archives of Disease in Childhood, Pediatric Research, Developmental Medicine and Child Neurology, Acta Paediatrica, European Journal of Pediatrics, Neuropediatrics, New England Journal of Medicine, Lancet and British Medical Journal. We searched the National Library of Medicine (USA) database (via PubMed) and the Cochrane Central Register of Controlled Trials (CENTRAL, 2012, Issue 10) through to 31 October 2012. We did not limit the searches to the English language, as long as the article included an English abstract. We read identified articles in the original language or translated. We included randomised or quasi-randomised controlled trials in which phenobarbital was given to preterm infants identified as being at risk of IVH because of gestational age below 34 weeks, birthweight below 1500 g or respiratory failure. Adequate determination of IVH by ultrasound or CT was also required. In addition to details of patient selection and control of bias, we extracted the details of the administration of phenobarbital.

    To determine the prognosis of seizures in epileptic children and identify early predictors of intractable childhood epilepsy. All children (aged 1 month to 16 years) with idiopathic or cryptogenic epilepsy who were treated and followed at the centre during the study period were included. The patients who had marked seizures even after two years of adequate treatment were labeled as intractable epileptics (cases). Children who had no seizure for more than one year at last follow-up visit were the controls. Adequate treatment was described as using at least three anti-epileptic agents either alone or in combination with proper compliance and dosage. Records of these patients were reviewed to identify the variables that may be associated with seizure intractability. Of 442 epileptic children, 325 (74%) intractable and 117 (26%) control epileptics were included in the study. Male gender (OR=3.92), seizures onset in infancy >10 seizures before starting treatment (OR=3.76), myoclonic seizures (OR=1.37), neonatal seizures (OR=3.69), abnormal EEG (OR=7.28) and cryptogenic epilepsy (OR=9.69) and head trauma (OR=4.07) were the factors associated with intractable epilepsy. Seizure onset between 5-7 years of age, idiopathic epilepsy, and absence seizures were associated with favourable prognosis in childhood epilepsy. Intractable childhood epilepsy is expected if certain risk factors such as type, age of onset, gender and cause of epilepsy are found. Early referral of such patients to the specialized centres is recommended for prompt and optimal management. (author)

    Full Text Available Epilepsy is the main neurological condition in children and adolescents. Unfortunately patients with medical refractory epilepsy are more susceptible for clinical complications and death. We report a prospectively evaluated cohort of children followed for approximately 10 years. Fifty-three of 1012 patients died. Forty-two patients died due to epilepsy or its clinical complications and the main causes of death were pneumonia (in 16 cases, sepses (in 9 patients, status epilepticus (in 8 patients. In 11 patients cause of death was sudden unexpected death in epilepsy (SUDEP. Mental retardation was significantly more frequent in patients who did not die from SUDEP. SUDEP may be a significant condition associated with mortality in children and adolescents with epilepsy.

    Background: It is important to choose an appropriate antiepileptic drug (AED) to manage partial epilepsy. Traditional AEDs, such as carbamazepine (CBZ) and valproate (VPA), have been proven to have good therapeutic effects. However, in recent years, a variety of new AEDs have increasingly been used as first-line treatments for partial epilepsy. As the studies regarding the effectiveness of new drugs and comparisons between new AEDs and traditional AEDs are few, it is determined that these are areas in need of further research. Accordingly, this study investigated the long-term effectiveness of six AEDs used as monotherapy in patients with partial epilepsy. Methods: This is a retrospective, long-term observational study. Patients with partial epilepsy who received monotherapy with one of six AEDs, namely, CBZ, VPA, topiramate (TPM), oxcarbazepine (OXC), lamotrigine (LTG), or levetiracetam (LEV), were identified and followed up from May 2007 to October 2014, and time to first seizure after treatment, 12-month remission rate, retention rate, reasons for treatment discontinuation, and adverse effects were evaluated. Results: A total of 789 patients were enrolled. The median time of follow-up was 56.95 months. CBZ exhibited the best time to first seizure, with a median time to first seizure of 36.06 months (95% confidential interval: 30.64–44.07). CBZ exhibited the highest 12-month remission rate (85.55%), which was significantly higher than those of TPM (69.38%, P = 0.006), LTG (70.79%, P = 0.001), LEV (72.54%, P = 0.005), and VPA (73.33%, P = 0.002). CBZ, OXC, and LEV had the best retention rate, followed by LTG, TPM, and VPA. Overall, adverse effects occurred in 45.87% of patients, and the most common adverse effects were memory problems (8.09%), rashes (7.76%), abnormal hepatic function (6.24%), and drowsiness (6.24%). Conclusion: This study demonstrated that CBZ, OXC, and LEV are relatively effective in managing focal epilepsy as measured by time to first seizure

    Full Text Available To evaluate the RARE (Réseau Action-Recherche sur l'Epilepsie program, a model of managing and treating people with epilepsy (PWE at a primary health-care level in rural areas of Mali, we assessed treatment efficacy and compliance of patients who underwent the first year follow-up.A network of rural general practitioners (GPs settled in six rural districts of the regions of Koulikoro, Segou and Sikasso, was involved in the diagnosis, evaluation and monitoring of all the identified PWE and in the distribution of phenobarbital (PB. All the participants were included in a prospective database and followed-up by GPs at 4 months intervals during the first year. Seizure frequency, treatment doses and appearance of adverse events (AEs were systematically recorded. Efficacy was evaluated in terms of reduction of seizures frequency while noncompliance in terms of time to study withdrawal for any cause.596 patients treated with PB were included in the analysis. Of these, 74.0% completed the first year follow-up. At the final visit, 59.6% were seizure-free: 31.0% for 12 months, 10.2% for 8 months and 18.4% for 4 months. Adults and patients with convulsive seizures were the most drug-resistant (p<0.002. Few AEs were recorded. The multivariate analysis showed that being a woman, presenting convulsive seizures, having more than 5 seizures/month and had never be treated were predictors of withdrawal (p ≤ 0.05 at 12 months.This study showed a good response and compliance to the treatment and allowed the identification of some factors associated with failure of management in a setting very near to clinical practice. Awareness campaigns are needed to assure a broader accessibility to treatment and to improve the compliance and continuity with treatment programs.

  3. Temporal Lobe Epilepsy in Children

    The temporal lobe is a common focus for epilepsy. Temporal lobe epilepsy in infants and children differs from the relatively homogeneous syndrome seen in adults in several important clinical and pathological ways. Seizure semiology varies by age, and the ictal EEG pattern may be less clear cut than what is seen in adults. Additionally, the occurrence of intractable seizures in the developing brain may impact neurocognitive function remote from the temporal area. While many children will respond favorably to medical therapy, those with focal imaging abnormalities including cortical dysplasia, hippocampal sclerosis, or low-grade tumors are likely to be intractable. Expedient workup and surgical intervention in these medically intractable cases are needed to maximize long-term developmental outcome. PMID:22957247

    Patients with epilepsy, including children, have an increased mortality rate when compared to the general population. Only few studies on causes of mortality in childhood epilepsy exist and pediatric SUDEP rate is under continuous discussion. To describe general mortality, incidence of sudden unexpected death in epilepsy (SUDEP), causes of death and age distribution in a pediatric epilepsy patient population. The study retrospectively examined the mortality and causes of death in 1974 patients with childhood-onset epilepsy at a tertiary epilepsy center in Denmark over a period of 9 years. Cases of death were identified through their unique civil registration number. Information from death certificates, autopsy reports and medical notes were collected. 2.2% (n = 43) of the patient cohort died during the study period. This includes 9 patients with SUDEP (8 SUDEP cases per 10,000 patient years). 9 patients died in the course of neurodegenerative disease and 28 children died of various causes. Epilepsy was considered drug resistant in more than 95% of the deceased patients, 90% were diagnosed with intellectual disability. Mortality of patients that underwent dietary epilepsy treatment was slightly higher than in the general cohort. There were no epilepsy-related deaths due to drowning. This study confirms that SUDEP must not be disregarded in the pediatric age group. The vast majority of SUDEP cases in this study displays numerous risk factors similar to those described in adult epilepsy patients. Including SUDEP, only 30% of the mortality was directly seizure related. Copyright © 2013 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

    INTRODUCTION: Delirium tremens (DT) is the most severe manifestation of alcohol withdrawal which--if untreated--has a high rate of mortality. Barbiturates are the most effective drug but respiratory depression may occur. In the present study we investigated the frequency of respiratory problems...... to ketoacidosis. The death could not be attributed to the phenobarbital treatment. CONCLUSION: In conclusion, we found that the frequency of phenobarbital-induced respiratory depression was low. However, if the DT was complicated with pneumonia, life-threatening respiratory insufficiency could be the outcome...

    Drug treatment of neonates and infants and its long-term consequences on drug responses have emerged in recent years as a major challenge for health care professionals. In the current study, we use phenobarbital as a model drug and mouse as an in vivo model to demonstrate that the dose of phenobarbital and age of treatment are two key factors for the persistent induction of gene expression and consequential increases of enzyme activities of Cyp2b, Cyp2c, and Cyp3a in adult livers. We show that phenobarbital treatment at early life of day 5 after birth with a low dose (phenobarbital treatment with a high dose (>200 mg/kg) significantly increases expression and enzyme activities of these P450s in adult liver. We also demonstrate that phenobarbital treatment before day 10 after birth, but not at later ages, significantly increases mRNAs, proteins, and enzyme activities of the tested P450s. Such persistent induction of P450 gene expression and enzyme activities in adult livers by phenobarbital treatment only occurs within a sensitive age window early in life. The persistent induction in gene expression and enzyme activities is higher in female mice than in male mice for Cyp2b10 but not for Cyp2c29 and Cyp3a11. These results will stimulate studies to evaluate the long-term impacts of drug treatment with different doses at neonatal and infant ages on drug metabolism, therapeutic efficacy, and drug-induced toxicity throughout the rest of life.

    Prior research has shown that attention-deficit/hyperactivity disorder (ADHD) and epilepsy are frequently comorbid and that both disorders are associated with various attention and memory problems. Nonetheless, limited research has been conducted comparing the two disorders in one sample to determine unique versus shared deficits. Hence, we investigated differences in working memory and short-term and delayed recall between children with ADHD, focal epilepsy of mixed foci, comorbid ADHD/epilepsy and controls. Participants were compared on the Core subtests and the Picture Locations subtest of the Children’s Memory Scale (CMS). Results indicated that children with ADHD displayed intact verbal working memory and long-term memory (LTM), as well as intact performance on most aspects of short-term memory (STM). They performed worse than controls on Numbers Forward and Picture Locations, suggesting problems with focused attention and simple span for visual-spatial material. Conversely, children with epilepsy displayed poor focused attention and STM regardless of modality assessed, which affected encoding into LTM. The only loss over time was found for passages (Stories). Working memory was intact. Children with comorbid ADHD/epilepsy displayed focused attention and STM/LTM problems consistent with both disorders, having the lowest scores across the four groups. Hence, focused attention and visual-spatial span appear to be affected in both disorders, whereas additional STM/encoding problems are specific to epilepsy. Children with comorbid ADHD/epilepsy have deficits consistent with both disorders, with slight additive effects. This study suggests that attention and memory testing should be a regular part of the evaluation of children with epilepsy and ADHD. PMID:26156331

    The objective was to test whether the five-domain structure of the Measure of Processes of Care (MPOC-20) was observed in a sample of children with epilepsy and, if not, to propose adaptations to improve its utility in this population. Data came from the Health-Related Quality of Life in Children with Epilepsy Study (HERQULES)-a multicenter prospective cohort study (n = 374) following children 4-12 years of age for 2 years after diagnosis. Confirmatory factor analysis (CFA) tested the applicability of the five domains/factors in a sample of children with epilepsy approximately 6 months following diagnosis (n = 311). Goodness-of-fit statistics were used to examine sources of ill model fit, and modification indices guided the model modification process where there was strong theoretical rationale for changes. The five-factor model described by the originators of the MPOC-20 was found to be inadmissible in children with epilepsy, with four of the five factors demonstrating high correlations (r > 0.85). Upon merging the intercorrelated factors, a two-factor solution with a mediocre fit emerged (Root Mean Square Error of Approximation (RMSEA) = 0.080, Comparative Fit Index (CFI) = 0.902, Standardized Root Mean Square Residual (SRMR) = 0.060). Modification indices identified four items as the source of poor model fit. Removing these four items and reperforming the CFA resulted in an adequate model fit and a revised 16-item MPOC (RMSEA = 0.057, CFI = 0.958, SRMR = 0.036). The two factors are "Family/Care Provider Interaction" and "Providing Information." Results suggest that the MPOC-16 better reflects family-centered care (FCC) in children with epilepsy than the original MPOC-20. The benefit of having fewer factors is that scoring is simpler and the interpretation of the results is easier. This was the first investigation of the factor structure of the MPOC-20 on a sample entirely composed of children with epilepsy. These results add to evidence that the factor structure

ESL is a pro-drug metabolized to its major active metabolite eslicarbazepine. Despite the fact that the exact mechanism of action has not been fully elucidated, it is thought to involve inhibition of voltage-gated sodium channels (VGSC. ESL inhibits sodium currents in a voltage-dependent way by an interaction predominantly with the inactivated state of the VGSC, thus selectively reducing the activity of rapidly firing (epileptic neurons. ESL reduces VGSC availability through enhancement of slow inactivation. In Phase III studies, adjunctive therapy with ESL 800 or 1,200 mg/day leads to a significant decrease in the seizure frequency in adults with refractory partial onset epilepsy. Based on these results, ESL has been approved in Europe (by the European Medicines Agency and in the United States (by the US Food and Drug Administration as add-on therapy. Data on efficacy and safety have been confirmed by 1-year extension and real life observational studies. Recently, based on results from two randomized, double-blind, historical control Phase III trials, ESL received US Food and Drug Administration approval also as a monotherapy for patients with partial onset epilepsy. In the pediatric setting, encouraging results have been obtained suggesting its potential role in the management of epileptic children. Overall ESL was generally well tolerated. The most common adverse events were dizziness, somnolence, headache, nausea

    To evaluate measures of epilepsy-specific impact currently available for use with children and adolescents. The relative merits of the different measures are examined. Four published epilepsy-specific impact measures, the Epilepsy and Learning Disabilities Quality of Life Scale (ELDQOL), the Health-related Quality of Life in Children with Epilepsy (HRQoLCE); the Impact of Childhood Neurologic Disability Scale (ICND), the Quality of Life in Epilepsy Inventory for Adolescents (QOLIE-AD-48), and the Quality of Life for Children with Epilepsy (QOLCE) were reviewed. There exist several shortcomings with the available measures on various psychometric criteria with not one of the currently available measures reaching acceptable psychometric standards in terms of reliability and validity. Of note are the particular inadequacies in the validation of scale content; with there being no investigation of the existence of age or ability effects for the items in any of the questionnaires reviewed. There is a clear demand for a psychometrically robust measure of subjective impact of epilepsy for children and adolescents, which is applicable to a wide age and ability range. At present, the efforts of the Canadian Pediatric Epilepsy Network with the recent publication of a novel measure holds much promise for the future. It is advocated that further efforts are made to further establish the psychometric properties of these scales and for their integration within a comprehensive outcome model for use in the evaluation of clinical interventions.

By simply tailoring the drug regimen to an individual's circadian rhythm, recent studies suggest one can improve the effectiveness of antiepileptic drugs, while reducing side effects. Daily variations in seizure occurrence and drug side effects create optimal timing windows for delivery of medication. Conversely, in certain epilepsy syndromes, there is growing evidence that both sleep and circadian rhythm can be distorted or misaligned. Thus, therapeutic re-entrainment of rhythms via application of zeitgebers (chronobiotics may represent an untapped opportunity for improving patient quality of life.

    Children suffering from epilepsy face severe difficulties in daily life. However, data about the self-assessment of children are scarce. From October 2013 to February 2014, patients aged 6-18years suffering from epilepsy were consecutively invited (i) to take part in a structured interview and (ii) to draw a picture about their self-assessment of epilepsy. Eighty-four children and their parents agreed to participate: (i) 63/84 (75%) of the children named their disease correctly; contagiousness was assumed by 8/84 (10%); 81/84 (96%) knew whether they have to take medication; 36/69 (52%) of the children taking long-term medication reported the name(s) of their medication; 8/69 (12%) believed that their medication will cure their disease; 45/84 (54%) named specific precautions to prevent harm from seizures; 6/84 (7%) believed that nonadherence to safety precautions would cause new seizures; and 23/84 (27%) believed that they are worse off than healthy children. (ii) 67/84 (80%) drew a picture titled "This is how I feel when I have a seizure". Specific symptoms [17/67 (25%)] and the interaction between child and environment [12/67 (18%)] were the most common subjects. Most children with epilepsy had rather good knowledge about medication; half of the children knew specific safety precautions. The children were often able to describe their seizures well. Pictures drawn by patients can give an insight into their experiences. Teaching programs should, among others, address the fear of contagiousness of epilepsy in some children and the fact that children with epilepsy might feel disadvantaged.

    2014-07-01

    Despite worldwide campaigns to enhance public awareness, understanding and acceptability of epilepsy, stigmatising feelings remain among children with epilepsy and their families. Stigma can be internally felt by the child (shame and embarrassment) or enacted by others (discrimination). Many children with epilepsy and their parents fear disclosure of the condition and exercise a variety of disclosure or concealment strategies. Maintaining these strategies can have a negative, stressful impact on the child's social and psychosocial development and quality of life. Continuing dialogue among families, friends, teachers and health professionals should be initiated and supported.

    Decreased DDT, DDD, DDE in blood and DDA in urine followed phenobarbital treatments (10 mg/kg/day, 11 days, intramuscular (im)) in three male rhesus monkeys (Macaca mulatta). Animals were fed DDT diets containing up to 500 ppm DDT during a 3-year period. Induction of liver monooxygenases was confirmed by reduced in vivo antipyrine plasma half-life and increased in vitro oxidation rates of dihydroisodrin, p-nitroanisole and benz(alpha)pyrene by homogenates of liver obtained from closed needle biopsy. Chlorohydrocarbon blood levels significantly decreased during the induction period (days 1-11). Concentrations on day 28 were at or below pre-DDT exposure levels. Urine DDA gradually decreased in all monkeys from days 16 to 28.

    People with epilepsy are at increased risk of accidents and injuries but, despite several studies on this subject, data regarding preventable causes are still contradictory. The aim of this study was to investigate the relationship between injuries, side effects of antiepileptic drugs (AEDs) and depression. Data from a consecutive sample of adult patients with epilepsy attending the outpatient clinics at St George's University Hospital in London were included. All patients were asked if they had had any injury since the last clinic appointment and completed the Liverpool Adverse Event Profile (LAEP) and Neurological Disorders Depression Inventory for Epilepsy. Among 407 patients (243 females, mean age 43.1 years), 71 (17.4%) reported injuries since the last appointment. A two-step cluster analysis revealed two clusters with the major cluster (53.5% of the injured group) showing a total score for LAEP ≥45, a positive Neurological Disorders Depression Inventory for Epilepsy screening and presence of AED polytherapy. A total score for LAEP ≥45 was the most important predictor. Antiepileptic drug treatment should be reviewed in patients reporting injuries in order to evaluate the potential contribution and burden of AED side effects. © 2017 EAN.

    Objective  The objective of this study was to evaluate the correlation between fitness and health-related quality of life (HRQoL) in children with idiopathic epilepsy compared with a healthy matched control group. Methods  In this study, 107 children conducted a 6-minute walk test, anthropometric parameters were measured, and HRQoL was assessed using a standardized questionnaire (KINDL-R). Children were divided into two groups: (1) the patient group ( n  = 48) and (2) the healthy control group ( n  = 59). Results  HRQoL of children with focal epilepsy was greater when compared with healthy children and children with generalized epilepsy. A significant association could be demonstrated for the 6-minute walk distance and mental wellbeing in children with epilepsy but not in healthy children. Furthermore, a negative correlation between the HRQoL and the amount of time spent in front of TV and computer in children with epilepsy and healthy children was seen. In children with focal epilepsy, a significant negative correlation could be shown between school sport and mental wellbeing as well as between school sport and self-esteem. Conclusion  HRQoL in children with idiopathic epilepsy is significantly associated with physical fitness and might be positively influenced by an adequate education of patients and parents, a reduction of consumption of computer and TV in combination with age- and disease-adapted physical activity and sports.

    There are many treatments being developed for patients with epilepsy, including anti-epileptic drugs, ketogenic diet and vagus nerve stimulation. To date, there is a lack of valid methods to predict at an early stage the therapeutic effects on patients with epilepsy who receive one of these treatments. Our previous studies revealed that epileptiform discharges which were observed in patients with epilepsy were significantly decreased while listening to Mozart K.448. In this study, we attempted to develop a useful marker by utilizing a quantitative electroencephalogram (qEEG) method in analyzing the features of EEG to early evaluate the effect of the music on children with epilepsy, even without epileptiform discharges. EEG segments from 19 Taiwanese children who were selected from a large screen study of music effect (eight boys and 11 girls) diagnosed with epilepsy were analyzed. EEG examinations were performed in two parallel periods in each patient; before, and while listening to Mozart K.448's first movement (8 min 22s) and EEG data were compared by qEEG. EEG segments were classified into music effective/ineffective group. The term "effective" was defined as patient exposure to music resulting in over a 25% reduction in epileptiform discharges. On the contrary, the term "ineffective" was defined as patient exposure to music resulting in less than a 5% reduction in epileptiform discharges. There were four global feature descriptors selected for the music effective/ineffective classification. Two descriptors, DecorrTime_avg_AVG and DecorrTime_std_AVG, were related to the EEG feature "decorrelation" whereas the other two descriptors, RelPowGamma_avg_SNR and RelPowGamma_std_SNR, were related to "relative power of gamma." There were significantly higher RelPowGamma_std_SNR (0.190±0.133 vs. -0.026±0.119, p=0.0029), DecorrTime_std_AVG (0.005±0.004 vs. 0.0003±0.0016, p=0.0055), DecorrTime_avg_AVG (0.005±0.005 vs. -0.002±0.008, p=0.0179), and Rel

    Full Text Available Epilepsy’s overall prevalence in Colombia is 1.13%. Its prevalence in patients aged over 65 could be around 1.5%. Objective: describe demographic and clinical characteristics of patients older than 65 years of age with epilepsy. Materials and methods: A cross-sectional descriptive study was carried out in two high complexity hospitals in Bogotá, Colombia during 2005-2008. Demographic data were compiled and patients characterized regarding the type, frequency and diagnosis of seizures (based on ILAE classification, probable etiology, having a family background of epilepsy, and current pharmacological management. Results: 211 clinical histories were reviewed and 179 of them selected. Mean patient age was 75 (65-98 and average age at onset of epilepsy was 67.5 (7-93. 84% of the seizures were classified as being focal. The most frequently occurring diagnosis was symptomatic focal epilepsy (94.4%. 74 cases (41.3% had an etiological diagnosis. The most important cause was cerebrovascular disease (61 patients. First generation anti-epileptic drugs were the most used ones (99%. 81/104 patients were found not to be free from epileptic episodes. Conclusions: Most seizures have a partial beginning, resulting from symptomatic partial epilepsy as a consequence of a vascular lesion. Pharmacological treatment must be considered following the first seizure. Treatment with second generation anti-epileptic drugs such as Lamotrigine, Gabapentin, Levetiracetam and Topiramate must be begun for minimizing secondary effects and low doses must be maintained from the start of treatment. Costs may limit the use of the above antiepileptic drugs, in such cases Phenytoin and Carbamazepine may be used with extreme caution.

    The present study aimed to establish population pharmacokinetic model for phenobarbital (PB), examining and quantifying the magnitude of PB interactions with other antiepileptic drugs concomitantly used and to demonstrate its use for individualization of PB dosing regimen in adult epileptic patients. In total 205 PB concentrations were obtained during routine clinical monitoring of 136 adult epilepsy patients. PB steady state concentrations were measured by homogeneous enzyme immunoassay. Nonlinear mixed effects modelling (NONMEM) was applied for data analyses and evaluation of the final model. According to the final population model, significant determinant of apparent PB clearance (CL/F) was daily dose of concomitantly given valproic acid (VPA). Typical value of PB CL/F for final model was estimated at 0.314 l/h. Based on the final model, co-therapy with usual VPA dose of 1000 mg/day, resulted in PB CL/F average decrease of about 25 %, while 2000 mg/day leads to an average 50 % decrease in PB CL/F. Developed population PB model may be used in estimating individual CL/F for adult epileptic patients and could be applied for individualizing dosing regimen taking into account dose-dependent effect of concomitantly given VPA.

    To compare sleep habits and disturbances between Malaysian children with epilepsy and their siblings (age range 4-18 years) and to determine the factors associated with greater sleep disturbance. The Sleep Disturbance Scale for Children (SDSC) questionnaire was completed by the primary caregiver for 92 epileptic children (mean age 11.1 years, 50 male, 42 females) and their healthy siblings (mean age 11.1 years, 47 males, 45 females). Details of sleep arrangements and illness severity were obtained. Multiple regression analysis was used to determine factors associated with high Total SDSC scores in epileptic patients. Compared with their siblings, epileptic children had significantly higher total SDSC score (difference between means 8.7, 95% confidence interval (CI) 6.4-11.1) and subscale scores in disorders of initiating and maintaining sleep (3.9, 95% CI 2.8-5.2), sleep-wake transition disorders (2.1, 95% CI 1.3-2.9), sleep-disordered breathing (0.7, 95% CI 0.3-1.1) and disorders of excessive sleepiness (1.5, 95% CI 0.6-2.4). Epileptic children had a higher prevalence of co-sleeping (73.7% vs 31.5%) and on more nights per week (difference between means 3, 95% CI 2.0-3.9) than their siblings. Higher Epilepsy Illness Severity scores were associated with higher total SDSC scores (P= 0.02). Co-sleeping was highly prevalent in children with epilepsy, who also had more sleep disturbances (especially problems with initiating and maintaining sleep and sleep-wake transition disorders) than their siblings. Epilepsy severity contributed to the sleep disturbances. Evaluation of sleep problems should form part of the comprehensive care of children with severe epilepsy.

    This study investigated the possible presence of sensory-motor developmental impairments in preschool children with epilepsy and explored epilepsy impact on their activities and quality of life and on the stress load of their family. Study participants were children aged 2-6years diagnosed with epilepsy without any other comorbidities (epi-only children). The instruments used for assessment included the Neurological, Sensory, Motor, Developmental Assessment (NSMDA) scale for sensory-motor development, the Impact of Childhood Neurologic Disability Scale (ICNDS), and the Impact of Pediatric Epilepsy Scale (IPES) for disease impact on disability and Quality of Life (QoL), as well as the Pediatric Outcomes Data Collection Instrument (PODCI) for functional health status, and the Parental Stress Scale (PSS) for the family stress load. Required data were obtained from direct testing or observation of children's activities and mother-supplied answers to questions. Eighty-two children were investigated. The NSMDA scores were in the normal development range 6-8. Significant moderate impact of the disease on disability and QoL was estimated with the ICNDS and IPES instruments. The PODCI scores were similar to healthy population levels except for the happiness dimension which was better for children with epilepsy. PSS were significantly above normal. The functional health and QoL of the children as well as their family stress were found to be positively correlated with increasing age. It is found that epilepsy does not degrade neuromotor development and functional health status of preschool epi-only children, though it has a significant impact on their neurological disability and QoL and the stress level of their families; this impact seems to decrease with age.

    2012-04-01

    Full Text Available Background Epilepsy remains one of the most frequently occurring pediatric problems. Approximately 10-15% patients do not respond to conventional therapy. Topiramate as a novel antiepileptic drug has a broad spectrum activity, presumably indicative of multiple anti-seizure mechanisms. Previous studies of topiramate as adjunctive and monotherapy in adults have shown beneficial effects. The objective of this research was to evaluate the efficacy and tolerability of topiramate sprinkle monotherapy in pediatric epilepsy. Methods This experimental research was conducted in the Pediatric Neurology outpatient clinic department, Soetomo hospital, Surabaya, involving 18 consecutive subjects. Subjects meeting the inclusion criteria were treated with topiramate sprinkle adjusted dose. Seizure frequency and side effects were observed in weeks 1, 4, 8, 12, 16, 20 and 24, respectively. Electro encephalogram (EEG and laboratory examinations were performed prior to and after 6 months of treatment. The t-test for related samples and McNemar test were utilized for statistical analysis. Results A total of 15 subjects completed the study. Topiramate-treated patients showed a statistically significant difference of seizure frequency reduction from 2.7 ± 1.16 to 0.13 ± 0.51 (p=0.000 with 93.7% patients being seizure free in 20 weeks. EEG recordings did not differ statistically in decrement of epileptiform activity in 20% subjects. About 7% subjects developed drowsiness and 33.3% subjects suffered from appetite suppression in the initial treatment. Laboratory results showed no abnormalities. Conclusions There was reduction of seizure frequency and no EEG recording alterations after topiramate sprinkle monotherapy. Topiramate as a monotherapy is highly effcicacious in childhood epilepsy.

    The aim of our study was to assess knowledge, attitudes, and behaviors of parents whose children were diagnosed with epilepsy. This cross-sectional study included 213 consecutive parents who accompanied their children, diagnosed with epilepsy, at regular checkups in the outpatient department of the Child and Adolescent Neurology and Psychiatry Clinic in Belgrade. Data were obtained through a questionnaire before completion of the child's neurological checkup, while clinical parameters of children with epilepsy were taken from medical records. Almost all respondents knew that epilepsy is not an infectious disease (99.5%), while the least proportion of parents (31.9%) knew that epilepsy is not, for the most part, hereditary. Parents felt that their family and friends should know that their child is suffering from epilepsy (average score: 4.3 out of 5). Also, parents felt the most confident in taking care of their child during seizures (4.7 out of 5), while they felt the least confident in letting their child go on school trips for several days (3.4 out of 5). Parental longer schooling (i.e., higher education level) was an independent predictor of higher epilepsy knowledge. Taking less number of medications was an independent predictor of more supportive parental behavior towards children with epilepsy. Some epilepsy-related issues still require improvement in parental knowledge. Ensuring education and support at community and school levels for both parents and children with epilepsy should be the principal goal of health-care service. Copyright © 2014 Elsevier Inc.

    Objective To study the state of peripheral T lymphocytes and cytokine levels in children with epilepsy. Methods Twenty children with epilepsy and 20 healthy age-matched children were recruited and their peripheral blood was collected. The activation of T lymphocytes was evaluated by detecting the expressions of CD25, CD69 and cytotoxic T lymphocyte-assicated antigen 4 (CTLA4). The function of T lymphocytes was evaluated by detecting the expressions of interferon γ (IFN-γ), tumor necrosis factor α (TNF-α), IL-17A and IL-6. The activation of regulatory T cells (Tregs) was evaluated by detecting the expression of IL-10. Results Children with epilepsy had higher expressions of CD25, CD69 and CTLA-4 in T lymphocytes than the controls did. The expressions of IFN-γ, TNF-α, IL-17A and IL-6 in T lymphocytes of children with epilepsy were higher than those of the controls. Frequency of Tregs producing IL-10 was higher in children with epilepsy as compared with the controls. Conclusion Peripheral T lymphocytes of children with epilepsy are activated and produce cytokines.

    The use of complementary and alternative medicine (CAM) is popular. Parents of children suffering from epilepsy may also consider administering CAM to their children. Systematic data about frequency of and motivations for CAM use, however, are scarce. In a university hospital's neuropaediatric department parents of patients aged 0-18 years suffering from epilepsy were consecutively invited to take part in a structured interview during 4 months in 2014. Of the invited parents, 164/165 (99%) agreed to participate. From those, 21/164 (13%) stated that they used CAM in their child. The highest independent predictive value of CAM use was the occurrence of adverse drug events (ADE) of anticonvulsants as judged by parents. Patients affected by ADE had a 5.6 higher chance of receiving CAM compared to patients without ADE. Most commonly used were homeopathy (14/21, 67%) and osteopathy (12/21, 57%). The internet was the most frequently used source of information (14/21, 67%). Of the parents, 10/21 (48%) described positive effects of CAM on seizure frequency, 12/21 (57%) on general condition of their child, and 20/21 (95%) wished to continue CAM for epilepsy therapy. From the non-users of CAM, 91/143 (66%) expressed the desire to learn more about CAM for epilepsy therapy. Our study was performed in a university hospital in a large urban city in Eastern Germany. CAM user rates can differ in other parts of Germany and Europe, in other institutions and for chronic diseases other than epilepsy. The main reason for CAM use was the occurrence of ADE of anticonvulsants. More than half of the parents saw a benefit of CAM for their children. Almost all parents wished to continue CAM use, even those who did not see concrete positive effects. Copyright © 2015 European Paediatric Neurology Society. Published by Elsevier Ltd.

    The objective of the study was to compare the psychiatric and behavioral side effect (PBSE) profiles of both older and newer antiepileptic drugs (AEDs) in children and adolescent patients with epilepsy. We used logistic regression analysis to test the correlation between 83 non-AED/patient related potential predictor variables and the rate of PBSE. We then compared for each AED the rate of PBSEs and the rate of PBSEs that led to intolerability (IPBSE) while controlling for non-AED predictors of PBSEs. 922 patients (≤18 years old) were included in our study. PBSEs and IPBSEs occurred in 13.8% and 11.2% of patients, respectively. Overall, a history of psychiatric condition, absence seizures, intractable epilepsy, and frontal lobe epilepsy were significantly associated with increased PBSE rates. Levetiracetam (LEV) had the greatest PBSE rate (16.2%). This was significantly higher compared to other AEDs. LEV was also significantly associated with a high rate of IPBSEs (13.4%) and dose-decrease rates due to IPBSE (6.7%). Zonisamide (ZNS) was associated with significantly higher cessation rate due to IPBSE (9.1%) compared to other AEDs. Patients with a history of psychiatric condition, absence seizures, intractable epilepsy, or frontal lobe epilepsy are more likely to develop PBSE. PBSEs appear to occur more frequently in adolescent and children patients taking LEV compared to other AEDs. LEV-attributed PBSEs are more likely to be associated with intolerability and subsequent decrease in dose. The rate of ZNS-attributed IPBSEs is more likely to be associated with complete cessation of AED. Copyright © 2017 European Paediatric Neurology Society. Published by Elsevier Ltd.

    The aim of this study is to explore and compare through polysomnography respiratory sleep parameters between children with idiopathic epilepsy and healthy children. Our cross-sectional study included 40 children with idiopathic epilepsy and 27 healthy children, who underwent overnight polysomnography. Data about sleep respiratory parameters were obtained and statistically analyzed. The level of statistical significance was set at 0.05. The prevalence of Obstructive Sleep Apnea Syndrome was significantly higher in the epilepsy group (35% vs 7.4%, pepilepsy group was 10.6 (95% Confidence Intervals: 3.08-37.08) in comparison to the control group. The mean value of the obstructive apnea-hypopnea index was significantly higher in children with epilepsy compared to healthy children (2.46±1.22 vs 1.21±0.83, p=0.027). The mean values of central apnea index and desaturation index were comparable between these two groups. Longest apnea duration was significantly higher in the group of poor seizure control. All other sleep respiratory variables did not differ significantly between children with poor and good seizure control and between children with generalized and focal epilepsy. Children with epilepsy seem to present more prominent sleep breathing instability in comparison to healthy children, which mainly includes a predisposition to obstructive respiratory events. More studies are needed to investigate the relationship between sleep apneas and seizure control. Copyright © 2016 Elsevier B.V. All rights reserved.

    The current study examined pre- and postoperative health-related quality of life (HRQL) across children with and without low intellectual ability. We also aimed to clarify the literature on postsurgical change by assessing domain-specific HRQL pre- and postoperatively in children with drug-resistant epilepsy. All patients (n=111) underwent resective epilepsy surgery between 1996 and 2016 at the Hospital for Sick Children in Toronto, comparing baseline and 1-year follow-up HRQL with the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-76). At the group-level, postsurgical change in HRQL was examined through linear mixed-effects modeling. Clinically important change in HRQL at the individual level was quantified using a standard error of measurement (SEM)-based criterion, and estimates were stratified by intellectual ability. Children with epilepsy and low intellectual ability had lower overall HRQL compared with those with normal intelligence (b=-10.45, SE=4.89, p=.035). No differences in change in HRQL related to intellectual level were found. In the broader sample, significant postoperative improvements were found for HRQL related to physical activity (b=8.28, SE=1.79, p<.001), social activity (b=15.81, SE=2.76, p<.001), and behavior (b=4.34, SE=1.35, p=.001). Postoperative improvements in physical and social HRQL were associated with better seizure control (p=.011). Conversely, cognitive and emotional domains of HRQL did not improve one year postoperatively, even in the presence of improved seizure control. Results suggest that children with low intellectual ability can expect to achieve similar improvements in HRQL after epilepsy surgery compared with those with normal intelligence. Further, while overall HRQL is shown to improve in children following epilepsy surgery, domain-specific change is nuanced and has important implications for health practitioners aiming to monitor treatment progress of patients.

    Benign epilepsy with centrotemporal spikes (BECTS) is a common epilepsy syndrome in childhood. Besides the occurrence of seizures, mild cognitive impairments and behavioral problems affecting language skills, spatial perception, memory, executive function, and academic achievement might be present. There is no international consensus about the decision whether or not to treat affected children. The influence of treatment on cognitive functions is debated. Patients diagnosed with BECTS were assessed in short term auditory memory, long-term verbal memory, intelligence and behavior using the "number recall" test from the Kaufman assessment battery for children, the "verbal learning memory test", the "culture free intelligence test" and the "child behavior checklist" prior to a randomized controlled antiepileptic therapy and after a treatment period of 6 months with either sulthiame or levetiracetam. 43 of 44 randomized patients were analyzed. One patient had to be excluded due to protocol violation. Patients who completed the study showed a non-significant improvement in parent-reported behavioral problems under therapy. Cognitive skills were not affected. The present data suggest that antiepileptic drug treatment of children with BECTS with either sulthiame or levetiracetam does not affect cognitive performance. Behavior improved in a subset of patients though not reaching statistical significance. Copyright © 2016 European Paediatric Neurology Society. Published by Elsevier Ltd. All rights reserved.

    2016-12-01

    When a child is diagnosed with epilepsy, not only has the child's life been disrupted but also the family's sense of normalcy. Although there is considerable literature discussing family concerns and social support issues in families with chronically ill children, a major gap lies in the exploration of how the specifics of childhood epilepsy affect parents and family operations. The purpose of this study was to identify psychosocial care needs of parents of children with epilepsy. Utilizing the Family Systems Nursing theory as a framework, this correlation study examined the relationships among social and community support, family needs, family empowerment, and family quality of life in 29 primary caregivers of a child with epilepsy. These families felt highly supported; they had low needs and high perceptions of empowerment. There was a negative association between social supports and the total family needs survey scale and the subscales of financial support, help regarding explaining to others, and professional support. There was no association between family empowerment or quality of life with parental perceptions of social support. In general, as parental perceptions of family needs increased, perceptions of familial social supports decreased. Further research is recommended to investigate varying socioeconomic status effects in families with children with pediatric epilepsy.

    2013-09-01

    Epilepsy is one of the most common neurological disorders. Global neurological knowledge is essential for differential diagnosis of epileptic syndromes due to the diversity of ictal semiology, causes and syndromes. Neurologists play an important role in planning the medical care for patients with epilepsy, as medication is the most fundamental therapeutic strategy. Some patients with early-onset epilepsy require joint care by pediatric neurologists, those with intractable epilepsy by neurosurgeons, and those with psychological comorbidity by psychiatrists, and neurologists should play a coordinating role. While there is a great need for neurologists to participate in epilepsy care, neurologists in Japan currently do not participate substantially in the epilepsy management system. It is necessary to train more neurologists who can provide epilepsy care and conduct basic and clinical research on epilepsy by providing continuous education on epilepsy for general neurologists as well as pre- and post-graduate medical students. Most of the patients who require long-term treatment experience many medical problems and social handicaps, such as adverse effects of medication, social stigma, educational disadvantages and difficulties in obtaining driver's license. To improve the quality of life of patients with epilepsy, it is desirable to build broad medical-social networks participated by patients, doctors, neurological nurses, psychologists, social workers, school teachers, managers of employment support facilities and care givers.

    In about 20-40% of patients, status epilepticus (SE) is refractory to standard treatment with benzodiazepines, necessitating second- and third-line treatments that are not always successful, resulting in increased mortality. Rat models of refractory SE are instrumental in studying the changes underlying refractoriness and to develop more effective treatments for this severe medical emergency. Failure of GABAergic inhibition is a likely cause of the development of benzodiazepine resistance during SE. In addition to changes in GABAA receptor expression, trafficking, and function, alterations in Cl(-) homeostasis with increased intraneuronal Cl(-) levels may be involved. Bumetanide, which reduces intraneuronal Cl(-) by inhibiting the Cl(-) intruding Na(+), K(+), Cl(-) cotransporter NKCC1, has been reported to interrupt SE induced by kainate in urethane-anesthetized rats, indicating that this diuretic drug may be an interesting candidate for treatment of refractory SE. In this study, we evaluated the effects of bumetanide in the kainate and lithium-pilocarpine models of SE as well as a model in which SE is induced by sustained electrical stimulation of the basolateral amygdala. Unexpectedly, bumetanide alone was ineffective to terminate SE in both conscious and anesthetized adult rats. However, it potentiated the anticonvulsant effect of low doses of phenobarbital, although this was only seen in part of the animals; higher doses of phenobarbital, particularly in combination with diazepam, were more effective to terminate SE than bumetanide/phenobarbital combinations. These data do not suggest that bumetanide, alone or in combination with phenobarbital, is a valuable option in the treatment of refractory SE in adult patients. Copyright © 2014 Elsevier B.V.

    Cognitive difficulties are common in epilepsy. Beyond reducing seizures and adjusting antiepileptic medications, no well-validated treatment exists in adults. Methylphenidate is used effectively in children with epilepsy and attention-deficit/hyperactivity disorder, but its effects in adults have not been systematically evaluated. We hypothesized that methylphenidate can safely improve cognition in adults with epilepsy. We detail here the open-label follow-up to a double-blind, placebo-controlled, single-dose study. Thirty epilepsy patients entered a 1-month open-label methylphenidate trial after a double-blind phase. Doses were titrated according to clinical practice and patient tolerance, ranging 20-40 mg/day. Primary measures included: Conners' Continuous Performance Test (CPT), Symbol-Digit Modalities Test (SDMT), and Medical College of Georgia Memory Test (MCG). Secondary measures were: Beck Depression Inventory, 2nd Edition (BDI-II), Beck Anxiety Inventory, Apathy Evaluation Scale (AES), Stimulant Side-Effect Checklist, Adverse Events Profile, Quality of Life in Epilepsy-89 (QOLIE-89), and seizure frequency. Fourteen healthy, nonmedicated controls were tested concurrently. Twenty-eight participants with epilepsy (13 men/15 women) completed the trial. Withdrawals occurred due to anxiety (n = 1) and fatigue (n = 1). Mean age was 36.4 years (range = 20-60). Epilepsy types were: focal (n = 21), generalized (n = 6), or unclassified (n = 1). Mean epilepsy duration was 12.3 years. Mean baseline seizure frequency was 2.8/month. There were significant improvements on methylphenidate for SDMT, MCG, CPT (the ability to discriminate between targets and nontargets [d'] hits, hit reaction time standard deviation, omissions, and commissions), and QOLIE subscales (energy/fatigue, attention/concentration, memory, and language; paired t tests; p ≤ 0.002). BDI-II and additional subscales also improved, at a lower level of statistical significance. Effect

    This open study explored whether methylphenidate could be tolerated and effective in improving the quality of life (QOL) and attention deficit hyperactivity disorder (ADHD) symptoms of children with epilepsy and ADHD. Twenty-five subjects (aged 10.1 +/- 3.0 years) with ADHD and epilepsy were recruited at an outpatient clinic in Seoul, Korea. We used the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE), ADHD rating scale (ARS) and clinical global impression (CGI) in this study. Osmotic-controlled release oral delivery system (OROS) methylphenidate, 1.0 +/- 0.4 mg/kg/day, was administered for 55.2 +/- 7.5 days. The QOL subscales including physical restriction (p = 0.005), self-esteem (p = 0.002), memory (p < 0.001), language (p = 0.005), other cognition (p < 0.001), social interaction (p = 0.002), behaviour (p < 0.001), general health (p = 0.002) and QOL (p < 0.001) were significantly increased and the ARS (p < 0.001) and CGI-Severity of illness scores (p < 0.001) were significantly reduced after medication. Although 60% of subjects had experienced adverse effects, most were tolerable and only two subjects withdrew from the study owing to unbearable adverse effects (anorexia and insomnia). Two subjects had seizure attacks during the study period without having to discontinue the trial drug. Despite limitations related to the small sample size and the open design of the present pilot study, our results suggest that OROS methylphenidate may be well tolerated and effective in reducing ADHD symptoms and improving QOL in this patient population.

    Evaluating the efficacy of the loading and tapering dose of Phenobarbital versus oral Morphine in the management of NAS. This randomized, open-label, controlled trial was conducted on 60 neonates born to illicit drugs dependent mothers at Vali-Asr and Akbar-Abadi hospitals, Tehran, Iran, who exhibited NAS requiring medical therapy. The neonates were randomized to receive either: Oral Morphine Sulfate or a loading dose of Phenobarbital followed by a tapering dose. The duration of treatment required for NAS resolution, the total hospital stay and the requirement for additional second line treatment were compared between the treatment groups. The Mean ± Standard Deviation for the duration of treatment required for the resolution of NAS was 8.5 ± 5 days in the Morphine group and 8.5 ± 4 days in the Phenobarbital group (P = 0.9). The duration of total hospital stay was 12.6 ± 5.6 days in the Morphine group and 12.5 ± 5.3 days in the Phenobarbital group (P = 0.7). 3.3 % in the Morphine group versus 6.6 % in the Phenobarbital group required adjunctive treatment (P = 0.5). There were no significant differences in the duration of treatment, duration of hospital stay, and the requirement for adjunctive treatment, between the neonates with NAS who received Morphine Sulfate and neonates who received a loading and tapering dose of Phenobarbital. This study is registered at the Iranian Registry of Clinical Trials ( www.irct.ir ) which is a Primary Registry in the WHO Registry Network. (Registration Number =  IRCT201406239568N8 ).

    Full Text Available Abstract Background children affected by refractory epilepsy could be at risk of malnutrition because of feeding difficulties (anorexia, chewing, swallowing difficulties or vomiting and chronic use of anticonvulsants, which may affect food intake and energy metabolism. Moreover, their energy requirement may be changed as their disabilities would impede normal daily activities. The aim of the present study was to evaluate nutritional status, energy metabolism and food intake in children with refractory epilepsy. Methods 17 children with refractory epilepsy (13 boys and 4 girls; mean age 9 ± 3,2 years; Body Mass Index 15,7 ± 3,6 underwent an anthropometric assessment, body composition evaluation by dual-energy X-ray absorptiometry, detailed dietetic survey and measurement of resting energy expenditure by indirect calorimetry. Weight-for-age, height-for-age (stunting and weight-for-height (wasting were estimated compared to those of a reference population of the same age. Results 40% of children were malnourished and 24% were wasted. The nutritional status was worse in the more disabled children. Dietary intake resulted unbalanced (18%, 39%, 43% of total daily energy intake derived respectively from protein, lipid and carbohydrate. Adequacy index [nutrient daily intake/recommended allowance (RDA × 100] was Conclusion many children with refractory epilepsy would benefit from individual nutritional assessment and management as part of their overall care.

    Male Wistar rats were irradiated with a single 600R dose of X-rays on the whole body. Chlorpromazine was given 30 min before phenobarbital. Phenobarbital sleeping time was prolonged by chlorpromazine both in irradiated and non-irradiated rats. On the 3rd day after irradiation the prolongation of the phenobarbital sleep by chlorpromazine was more marked than on the 6th day. No correlation between the pharmacodynamic action of phenobarbital and its cerebral level was noted. (author)

    The aims of this study were to record behavioral problems in children with epilepsy (CWE), compare the prevalence with that reported among healthy children without epilepsy, and investigate the risk factors. A child behavioral questionnaire for parents comprising 15 items was administered to the main caregiver of 108 CWE and 108 controls matched for age in Kilifi, Kenya. CWE had a higher mean score for reported behavioral problems than controls (6.9 vs 4.9, t = 4.7, P epilepsy also recorded more behavioral problems than those with inactive epilepsy (8.2 vs 6.2, t = − 2.9, P = 0.005). A significantly greater proportion of CWE (49% vs 26% of controls) were reported to have behavioral problems. Active epilepsy, cognitive impairment, and focal seizures were the most significant independent covariates of behavioral problems. Behavioral problems in African CWE are common and need to be taken into consideration in planning comprehensive clinical services in this region. PMID:22119107

    Aim The aim of this study was to determine the relationship between parent and child full-scale IQ (FSIQ) in children with epilepsy and in typically developing comparison children and to examine parent–child IQ differences by epilepsy characteristics. Method The study participants were 97 children (50 males, 47 females; age range 8–18y; mean age 12y 3mo, SD 3y.1mo) with recent-onset epilepsy including idiopathic generalized (n=43) and idiopathic localization-related epilepsies (n=54); 69 healthy comparison children (38 females, 31 males; age range 8–18y; mean age 12y 8mo, SD 3y 2mo), and one biological parent per child. All participants were administered the Wechsler Abbreviated Intelligence Scale. FSIQ was compared in children with epilepsy and typically developing children; FSIQ was compared in the parents of typically developing children and the parents of participants with epilepsy; parent–child FSIQ differences were compared between the groups. Results FSIQ was lower in children with epilepsy than in comparison children (pepilepsy did not differ from the FSIQ of the parents of typically developing children. Children with epilepsy had significantly lower FSIQ than their parents (pepilepsy than the comparison group (p=0.043). Epilepsy characteristics were not related to parent–child IQ difference. Interpretation Parent–child IQ difference appears to be a marker of epilepsy impact independent of familial IQ, epilepsy syndrome, and clinical seizure features. This marker is evident early in the course of idiopathic epilepsies and can be tracked over time. PMID:23216381

    In rats treated with phenobarbital (3x100 mg/kg, i.p.), liver G-6-P dehydrogenase activity increased by 70% in the cytosol and in the 9.000xg supernatant, and only by 20% in microsomes. Moreover, the phenobarbital treatment increased rat liver GSSG reductase activity by 30%. On the other hand, activity of the liver microsomal G-6-P dehydrogenase was found to increase by some 20% in whole body irradiated, both control and phenobarbital treated rats. In rats irradiated with 600 R prior to the first dose of the inducer there was not noted any increase in G-6-P dehydrogenase of the 9.000xg supernatant, and increase in the cytosol activity dropped to 38%. Thus, induction of the soluble liver G-6-P dehydrogenase by phenobarbital has turned out to be radiosensitive, whereas phenobarbital induction of GSSG reductase was unaffected by irradiation.

    Reducing the burden of pediatric mental illness requires greater knowledge of mental health and substance abuse (MHSA) outcomes in children who are at an increased risk of primary psychiatric illness. National data on hospital care for psychiatric illness in children with epilepsy are limited. We used the Kids' Inpatient Database (KID), the Healthcare Cost and Utilization Project (HCUP), and the Agency for Healthcare Research and Quality from 2003 to 2009 to examine MHSA hospitalization patterns in children with comorbid epilepsy. Nonparametric and regression analyses determined the association of comorbid epilepsy with specific MHSA diagnoses and examined the impact of epilepsy on length of stay (LOS) for such MHSA diagnoses while controlling for demographic, payer, and hospital characteristics. We observed 353,319 weighted MHSA hospitalizations of children ages 6-20; 3280 of these involved a child with epilepsy. Depression was the most common MHSA diagnosis in the general population (39.5%) whereas bipolar disorder was the most common MHSA diagnosis among children with epilepsy (36.2%). Multivariate logistic regression models revealed that children with comorbid epilepsy had greater adjusted odds of bipolar disorder (AOR: 1.17, 1.04-1.30), psychosis (AOR: 1.78, 1.51-2.09), sleep disorder (AOR: 5.90, 1.90-18.34), and suicide attempt/ideation (AOR: 3.20, 1.46-6.99) compared to the general MHSA inpatient population. Epilepsy was associated with a greater LOS and a higher adjusted incidence rate ratio (IRR) for prolonged LOS (IRR: 1.12, 1.09-1.17), particularly for suicide attempt/ideation (IRR: 3.74, 1.68-8.34). Children with epilepsy have distinct patterns of hospital care for mental illness and substance abuse and experience prolonged hospitalization for MHSA conditions. Strategies to reduce psychiatric hospitalizations in this population may require disease-specific approaches and should measure disease-relevant outcomes. Hospitals caring for large numbers of

    Epilepsy is one of the most frequent neurological disorders, both in children and adult persons. About 0.5-1% of general population suffer from epilepsy, which means that about 50 million people in the world are affected. First years of life and very late adulthood are periods in human's life particularly predisposing to epilepsy. Repetitive epileptic seizures may cause many life-threatening situations and significantly lower patient's quality of life. To the most serious complications belong status epilepticus and sudden unexpected deaths due to epilepsy (SUDEP). Absences from work or school caused by seizures, difficulties in social life, frequent injuries and necessity of polytherapy are also important for patients. All these factors result in low self-esteem and poor quality of life. The main aim of the treatment was control of epileptic seizures. However, despite of new antiepileptic drugs developed almost every year, in one third of all patients with epilepsy seizures remain out of control. Those patients are regarded to have "drug-resistant epilepsy". Despite of significant scale of the problem, there is no one definition of the phenomenon. In the presented review the authors outline current definitions, recent opinions on pathogenesis and risk factors, and provide practical rules of pharmacotherapy of epilepsy, which should help to restrict drug-resistancy.

    CYP2B6 is a drug-metabolizing enzyme expressed in the liver and brain that can metabolize bupropion (Zyban®, a smoking cessation drug), activate tobacco-smoke nitrosamines, and inactivate nicotine. Hepatic CYP2B6 is induced by phenobarbital and induction may affect in vivo nicotine disposition, while brain CYP2B6 induction may affect local levels of centrally acting substrates. We investigated the effect of chronic phenobarbital treatment on induction of in vivo nicotine disposition and CYP2B6 expression in the liver and brain of African Green (Vervet) monkeys. Monkeys were split into two groups (n=6 each) and given oral saccharin daily for 22 days; one group was supplemented with 20 mg kg−1 phenobarbital. Monkeys were given a 0.1 mg kg−1 nicotine dose subcutaneously before and after treatment. Phenobarbital treatment resulted in a significant, 56%, decrease (P=0.04) in the maximum nicotine plasma concentration and a 46% decrease (P=0.003) in the area under the concentration–time curve. Phenobarbital also increased hepatic CYP2B6 protein expression. In monkey brain, significant induction (Pphenobarbital treatment in monkeys resulted in increased in vivo nicotine disposition, and induced hepatic and brain CYP2B6 protein levels and cellular expression. This induction may alter the metabolism of CYP2B6 substrates including peripherally acting drugs such as cyclophosphamide and centrally acting drugs such as bupropion, ecstasy and phencyclidine.

    Epilepsy in two first years of life needs constant attention due to diagnostic and therapeutic difficulties. The aim of the study was to identify cause of symptomatic epilepsy in two first years of life children from miopolskie and podkarpackie provinces hospitalized in Pediatric Neurology Clinic of Children and Adolescents Neurology Cathedra UJ in Cracow. 102 children with epilepsy aged from 1 week to 24 months hospitalized between 1st of January 2006 and 31st of December 2007. The group included 47 girls and 55 boys. On the basis of clinical characteristics and results of additional examinations idiopathic epilepsy was diagnosed in 16/102 (13.3%) children and in remaining 86 (87.7%) symtopmatic epilepsy was established. Perinatal burdening was cause of epilepsy in 31/86 (33.72%) children. Other causes were identified in 32/54 children (59.3%) and in remaining 231 54 (40.7%) children the cause was not established. In 3/32 epilepsy occured in the course of hydrocephalus and in 3/32 children as one of CNS inflammation complications. Epilepsy as a result of vascular lesions and bleeding to CNS occured in 4 children. Multiple developmental deffects syndrome was diagnosed in 4 children and in 11 specific neurodevelopmental disorders were the cause of epilepsy. In 6 children epilepsy occured in the course of neurometabolic diseases, neurocutaneous syndromes and neoplasms. In children in two first years of life polimorphic seizures were diagnosed the most often (32/86 that is 37.2%) and tonic, tonic-clonic seizures were less often (21/86 that is 24.43%). Focal seizures occured in 20/86 (23.26%) patients, in 4/86 (4.65%) mioclonic jerks were observed and infantile spasms in 9/86 (10.46%).

    Social, cultural, psychological and many other factors significantly impact the lives of epileptic children and their families. Parental concerns towards their children are less known in south Asian children with epilepsy. We aimed to identify the parental concerns regarding their children and adolescents with epilepsy in Sri Lanka. We carried out qualitative study in 3 districts of Sri Lanka, comprising 16 in-depth interviews with parents of children and adolescents with epilepsy and 3 focus group discussions with primary caregivers of epileptic children and key informants (schoolteachers, public health staffs). Content analysis of the interview data was performed. Parental concerns were spread among seven themes that emerged from the content analysis. These concerns were about the child's functioning in areas such as physical, behavioural, psychological and social, education, concerns related to anti-epileptic therapy and epilepsy as a disease. Parents were more concerned about their child's safety, educational achievements and future prospects in terms of employment and marriage. Unpredictability of seizures, fear of stigma and unawareness of epilepsy were the main reasons voiced by the parents for having such concerns. Increased concern and perception of vulnerability was seen among parents whose children had epilepsy and co-morbid illness. Parental concerns towards their children and adolescents show a multidimensional construct. Unpredictability of seizures, fear of stigma and unawareness of epilepsy were identified as key influential factors in moulding the parental concerns. Copyright © 2015. Published by Elsevier Ltd.

    We aimed to study the epileptiform discharges (ED) and seizure risk in EEG of 12-18-year-old children of women with epilepsy (WWE). Children of WWE who were prospectively followed up in the Kerala registry of epilepsy and pregnancy (KREP), aged 12-16years (n=92; males 48, females 44) underwent clinical evaluation and a 30-min digital 18-channel EEG. The EEG showed epileptiform discharges in 13 children (5 males and 8 females). The EDs were generalized in 9 and focal in 4 (occipital 2, frontal 1, and centroparietal 1). They had significantly higher risk of ED (odds ratio 4.02, 95% CI 1.04-15.51) when compared to published prevalence of ED in healthy children. There were 2 children with epilepsy (one with localization-related epilepsy and the other generalized epilepsy). The children under study had a trend towards higher prevalence of epilepsy (odds ratio 3.39, 95% CI 0.82-13.77) when compared to age specific prevalence of epilepsy from community surveys in same region. Children of WWE showed increased risk of ED in EEG and trend towards increased seizure risk when compared to healthy children. Copyright © 2017 Elsevier Inc. All rights reserved.

    Orthodontic treatment is associated with a number of adverse effects, such as root resorption, pain, pulpal changes, periodontal disease, and temporomandibular dysfunction (TMD). Orthodontists should be aware of these effects and associated risk factors. Risk factors linked to root resorption include the duration of treatment, length, and shape of the root, trauma history, habits, and genetic predisposition. PMID:24151415

    This study evaluated the effect of topiramate (TPM) on the quality of life (QOL) in childhood epilepsy, using the Korean quality of life in childhood epilepsy (K-QOLCE) questionnaire. An open label, prospective, observational study of the families of 664 children with epilepsy from 41 centers was conducted. The parents completed the K-QOLCE at the baseline visit and again 6months after starting TPM treatment. The parents reported the seizure frequency at both assessment dates. Statistically significant improvements in all K-QOLCE domains except social functioning were found at 6months after starting TPM treatment from the baseline-scores (P<0.05). However, improved QOL scores were not dependent on the reduction in seizure frequency. TPM significantly improved QOL in children with epilepsy, suggesting its potential clinical benefits.

    ABSTRACT The ketogenic diet (KD), a high-fat, low-carbohydrate, and adequate-protein diet is an established, effective nonpharmacologic treatment option for intractable childhood epilepsy. The KD was developed in 1921 and even though it has been increasingly used worldwide in the past decade, many neurologists are not familiar with this therapeutic approach. In the past few years, alternative and more flexible KD variants have been developed to make the treatment easier and more palatable whi...

    Full Text Available The epilepsy treatment is to be based on existing general principles and standards of therapy with differential approach to each patient. Besides peculiarities of treatment of different types of seizures and forms of epilepsy there are also differential approaches to special groups of patients. To one of such groups are referred to women of reproductive age. These patients are referred to special group of risk due to the development of certain side effects of antiepileptic drugs (АED. This article focuses in details on peculiarities of treatment of women of reproductive age with epilepsy with accent made on tolerability and safety of the antiepileptic therapy. It is necessary to take into consideration, that at women neuroendocrinal disorders can be caused both by the disease itself – epilepsy (in such case disorders depend on the starting age, form of epilepsy, focal localization, duration of disorder and other factors, referred to the disease, as well as by the undertaken therapy. The articlehereunder considers only issues, referred to the treatment, i. e. AED side effects and its input in the decrease of life quality of women with epilepsy. As women’s reproductive function starts forming long ago before childbearing age, it is necessary for this category to comprise not only women and adolescents, but girls as well. Notwithstanding the fact that so called benign forms of epilepsy pass before the pubescence period (idiopathic focal epilepsies, several forms of idiopathic generalized epilepsy, in many cases the epilepsy, which has started in childhood, continues in the adult age as well. In the same time there can be possible remote negative consequences of the antiepileptic therapy, which can show at a woman of a reproductive age. The data, given in the article, witnesses the need of the right AED selection at women of reproductive age, suffering from epilepsy. The AED should be selected not only depending on the form of the

    In an retrospective uncontrolled long-term study in 30 children with intractable epilepsy, it was found that treatment with vigabatrin resulted in a seizure reduction of more than 50% at 1-year follow-up in 40% of the children. The responders were all children with partial seizures. Side effects...... were mild and did not lead to discontinuation of the drug. Increased numbers of seizures were seen in three cases. A moderate weight increase was seen in 27% of the children. At 5-year follow-up 7 children (23%) still maintained a seizure reduction of more than 50%. Trials of monotherapy in three...... seizure-free patients were unsuccessful. No further side effects were observed. A study of evoked potentials in 12 children showed no alteration in latency and amplitudes of VEP following treatment with vigabatrin. Our results show that in children vigabatrin seems to have a stable effect even though...

    Neurobehavioral comorbidities can be related to underlying etiology of epilepsy, epilepsy itself, and adverse effects of antiepileptic drugs. We examined the relationship between neurobehavioral comorbidities and putative risk factors for epilepsy in children with newly diagnosed epilepsy. We conducted a retrospective analysis of children aged ≤18years in 50 states and the District of Columbia, using the Truven Health MarketScan® commercial claims and encounters database from January 1, 2009 to December 31, 2013. The eligible study cohort was continuously enrolled throughout 2013 as well as enrolled for any days during a baseline period of at least the prior 2years. Newly diagnosed cases of epilepsy were defined by International Classification of Diseases, Ninth Revision, Clinical Modification-coded diagnoses of epilepsy or recurrent seizures and evidence of prescribed antiepileptic drugs during 2013, when neither seizure codes nor seizure medication claims were recorded during baseline periods. Twelve neurobehavioral comorbidities and eleven putative risk factors for epilepsy were measured. More than 6 million children were analyzed (male, 51%; mean age, 8.8years). A total of 7654 children were identified as having newly diagnosed epilepsy (125 per 100,000, 99% CI=122-129). Neurobehavioral comorbidities were more prevalent in children with epilepsy than children without epilepsy (60%, 99% CI=58.1-61.0 vs. 23%, CI=23.1-23.2). Children with epilepsy were far more likely to have multiple comorbidities (36%, 99% CI=34.3-37.1) than those without epilepsy (8%, 99% CI=7.45-7.51, Pepilepsy were detected in 28% (99% CI=26.9-29.6) of children with epilepsy. After controlling for demographics, neurobehavioral comorbidities, family history of epilepsy, and other risk factors than primary interest, neonatal seizures had the strongest independent association with the development of epilepsy (OR=29.8, 99% CI=23.7-37.3, Pepilepsy, those with both epilepsy and risk factors were

    Phenobarbital is used in hospice and palliative care to treat refractory symptoms. In end-of-life care, Food and Drug Administration approved routes of administration may be unreasonable based on patients' status. In these cases, phenobarbital may be administered subcutaneously for symptom management. However, according to the American Hospital Formulary Service, subcutaneous administration of commercially available injectable phenobarbital is cautioned due to possible skin reactions. This study evaluates the tolerability of phenobarbital administered subcutaneously. Of 69 patients and 774 distinct subcutaneous phenobarbital injections, 2 site reactions were recorded (2.9% of patients; 0.3% of injections). Both were mild, grade 1 reactions. Each patient continued to receive subcutaneous phenobarbital via newly placed ports with no additional reactions. Based on these findings, phenobarbital appears to be well tolerated when administered subcutaneously. © The Author(s) 2014.

  16. Epilepsy in the Elderly

    Directory of Open Access Journals (Sweden)

    Lu-An Chen

    2012-06-01

    Full Text Available Elderly people are the largest and continuously fastest growing population among patients with epilepsy. Elderly patients with epilepsy are very different from other age groups in many respects and clinicians shouldn’t treat them in the same way as younger adults. Accurate diagnosis of epilepsy in the elderly is much more difficult and atypical manifestations and misdiagnoses are certainly not the exception. Syncope is probably the most important differential diagnosis. High clinical suspicion and proper investigation are the best tools for prompt diagnosis. Etiologies of late-onset epilepsy are mainly symptomatic and cerebrovascular diseases are the most common causes in this age group, followed by degenerative diseases such as Alzheimer’s disease. It is appropriate to consider starting antiepileptic drug (AED treatment at the first-ever seizure in elderly patients who have remote symptomatic causes such as stroke and dementia. According to the high recurrence rate of seizure and the good response to AEDs in elderly patients, the proper choice from various AEDs for seizure control is very important. Decision-making for AED choice depends on many different factors, including pharmacological properties, efficacy, tolerability from side effects, drug interactions, and medical comorbidities. The newer AEDs with lesser adverse effects and fewer drug interactions appear to be reasonable treatment options for elderly patients. However, more evidence from clinical trials in this specific age group is warranted.

    2014-12-01

    Phenobarbital-responsive sialadenosis (PRS) is a rare idiopathic disease in dogs. Vomiting, retching, and gulping with bilateral enlargement of the submandibular salivary glands are the more frequent clinical signs. A thorough diagnostic examination must be performed to rule out the most important systemic etiologies involved with chronic vomiting, as there is no specific test to diagnose PRS. Diagnosis is confirmed clinically by a rapid and dramatic improvement of clinical signs after instauration of phenobarbital treatment. The aim of this article is to describe the clinical presentation, diagnostic findings, and outcome of a case series of 4 dogs with presumptive PRS. Copyright © 2015 Elsevier Inc.

    Epilepsy is a group of neurological conditions in which there is a pathological and enduring predisposition to generate recurrent seizures. Evidence over the last few decades suggests that epilepsy may be associated with increased sleep-disordered breathing, which may contribute towards sleep fragmentation, daytime somnolence, reduced seizure control, and cardiovascular-related morbidity and mortality. Chronic sleep-disordered breathing can result in loss of gray matter and cause deficits to memory and global cognitive function. Sleep-disordered breathing is a novel and independent predictor of sudden cardiac death and, as such, may be involved in the mechanisms leading to sudden unexpected death in epilepsy. Despite this, the long-term consequences of sleep-disordered breathing in epilepsy remain unknown, and there are no guidelines for screening or treating this population. There is currently insufficient evidence to indicate continuous positive airway pressure (CPAP) for the primary or secondary prevention of cardiovascular disease, and recent evidence has failed to show any reduction of fatal or nonfatal cardiovascular endpoints. Treatment of sleep-disordered breathing may potentially improve seizure control, daytime somnolence, and neurocognitive outcomes, but few studies have examined this relationship. In this review, we examine sleep-disordered breathing in epilepsy, and discuss the potential effect of epilepsy treatments. We consider the role of CPAP and other interventions for sleep-disordered breathing and discuss their implications for epilepsy management.

  20. Mechanisms of levetiracetam in the control of status epilepticus and epilepsy

    Directory of Open Access Journals (Sweden)

    Laxmikant S Deshpande

    2014-01-01

    Full Text Available Status epilepticus (SE is a major clinical emergency that is associated with high mortality and morbidity. SE causes significant neuronal injury and survivors are at a greater risk of developing acquired epilepsy and other neurological morbidities, including depression and cognitive deficits. Benzodiazepines and some anticonvulsant agents are drugs of choice for initial SE management. Despite their effectiveness, over 40% of SE cases are refractory to the initial treatment with two or more medications. Thus there is an unmet need of developing newer anti-SE drugs. Levetiracetam (LEV is a widely prescribed anti-epileptic drug that has been reported to be used in SE cases, especially in benzodiazepine-resistant SE or where phenytoin cannot be used due to allergic side-effects. Levetiracetam’s non-classical antiepileptic mechanisms of action, favorable pharmacokinetic profile, general lack of central depressant effects and lower incidence of drug interactions contributes to its use in SE management. This review will focus on LEV’s unique mechanism of action that makes it a viable candidate for SE treatment.

    The present study aimed to investigate the possible association of Toxoplasma gondii and Toxocara spp. infections with cryptogenic epilepsy in children. The study was carried out between June 2014 and March 2015. Total 90 children (40 with cryptogenic epilepsy, 30 with non-cryptogenic epilepsy, and 20 healthy control children) were evaluated to determine the anti-Toxocara and anti-T. gondii IgG seropositivity using ELISA kits. Epileptic cases were selected from those attending the pediatrics outpatient clinic of Benha University Hospital, Pediatrics Neurology Unit, and from Benha Specialized Hospital of children. The results showed that the level of anti-T. gondii IgG seropositivity was significantly higher among children with cryptogenic epilepsy (20%) than among children with non-cryptogenic children (0%). In healthy controls (10%), there was no association between toxocariasis seropositivity and cryptogenic epilepsy (only 5.7%; 4 out of 70 cases) among cases and 10% (2 out of 20) among controls. Among toxocariasis IgG positive cases, 3 (7.5%) were cryptogenic, and only 1 (3.3%) was non-cryptogenic. These statistically significant results support the association between T. gondii infection and cryptogenic epilepsy while deny this association with toxocariasis.

    Although cognitive and learning disorders have been described in patients with epilepsy, very few studies focus on specific disorders such as absence epilepsy. The aim of this study was to evaluate learning skills and academic performance in children and adolescents with absence epilepsy. Observational case-control study. Cases were chosen from the Central League against Epilepsy's clinic in Bogotá, Colombia. Controls were selected from a private school and matched with cases by age, school year, and sex. Medical history, seizure frequency, antiepileptic treatment, and academic performance were assessed. Academic abilities were tested with Batería de Aptitudes Diferenciales y Generales (BADyG) (a Spanish-language test of differential and general aptitudes). Data were analysed using Student t-test. The sample consisted of 19 cases and 19 controls aged between 7 and 16. In 15 patients, seizures were controlled; all patients had received antiepileptic medication at some point and 78.9% were actively being treated. Although cases had higher rates of academic failure, a greater incidence of grade retention, and more therapeutic interventions than controls, these differences were not significant. Similarly, there were no significant differences on the BADyG test, except for the immediate memory subcategory on which cases scored higher than controls (P=.0006). Children treated pharmacologically for absence epilepsy, whose seizures are controlled, have normal academic abilities and skills for their age. Copyright © 2013 Sociedad Española de Neurología.

    Prior research has shown that attention-deficit/hyperactivity disorder (ADHD) and epilepsy are frequently comorbid and that both disorders are associated with various attention and memory problems. Nonetheless, limited research has been conducted comparing the two disorders in one sample to determine unique versus shared deficits. Hence, we investigated differences in working memory (WM) and short-term and delayed recall between children with ADHD, focal epilepsy of mixed foci, comorbid ADHD/epilepsy and controls. Participants were compared on the Core subtests and the Picture Locations subtest of the Children's Memory Scale (CMS). Results indicated that children with ADHD displayed intact verbal WM and long-term memory (LTM), as well as intact performance on most aspects of short-term memory (STM). They performed worse than controls on Numbers Forward and Picture Locations, suggesting problems with focused attention and simple span for visual-spatial material. Conversely, children with epilepsy displayed poor focused attention and STM regardless of the modality assessed, which affected encoding into LTM. The only loss over time was found for passages (Stories). WM was intact. Children with comorbid ADHD/epilepsy displayed focused attention and STM/LTM problems consistent with both disorders, having the lowest scores across the four groups. Hence, focused attention and visual-spatial span appear to be affected in both disorders, whereas additional STM/encoding problems are specific to epilepsy. Children with comorbid ADHD/epilepsy have deficits consistent with both disorders, with slight additive effects. This study suggests that attention and memory testing should be a regular part of the evaluation of children with epilepsy and ADHD.

    To assess the role of resective brain surgery in childhood epilepsy. We retrospectively analysed the seizure outcomes in 55 children with epilepsy who had resective brain surgery between 1997 and 2012, at our centre. The children were 1.5-18 years at the time of surgery; their seizure onset was between 0.2 andto 15 years of age. 48 had refractory epilepsy. One child died of tumour progression. Follow-up duration in the survivors ranged from 2 to -16 years (mean: 9).Presurgical evaluation included clinical profiles, non-invasive V-EEG monitoring, neuroimaging with MRIs in all; SPECT and PET in selected patients. 54 had intraoperative ECoG. An Engel Class 1 outcome was seen in 78% of the cohort, with 67% being off all AEDs at the most recent follow-up. Children with tumours constituted the majority (56%), with 87% of this group showing a Class 1 outcome and 84% being off AEDs. Children with cortical dysplasia had a Class 1 outcome in 56%. Resective brain surgery is an efficacious option in some children with epilepsy. We found ECoG useful to tailor the cortical resection and in our opinion ECoG contributed to the good seizure outcomes. Copyright © 2015 European Paediatric Neurology Society.

    Epilepsy can be one of symptoms of the damage to CNS in children with neurodevelopmental deficits, it is more difficult however to diagnose seizures if they are the first symptom of severe brain damage. This retrospective research was conducted to study causes of symptomatic epilepsy in children aged 3-18 year hospitalized between 2006 and 2007 year in the Department of Pediatric Neurology. 156 children with symptomatic epilepsy occurred after 2 years of life were included. The diagnosis of symptomatic epilepsy was established including clinical picture, neuro-radiological tests and EEG. The information from parents was helpful to analyze the type of seizures. The clinical state of children was analyzed, especially psychomotor development, focal deficits, as well as results of CT and/or MRI, in some children psychological testing was performed, molecular or serological. 156 children with epilepsy were hospitalized, within encephalopathy was diagnosed in 61 children. In 42 children static encephalopathy was associated with birth trauma, in 7 progressive encephalopathy was diagnosed, in 1 child CO intoxication caused encephalopathy, and in 11 cases the cause was not identified. Malformations of nervous system were associated with epilepsy in 37 children, geneticaly determined syndromes in 6, and the head trauma in other 6 children. Disorders of vascular origin caused epilepsy in 16 children, and neuroinfections in 9 children. In 2 children epilepsy was associated with ADEM, and in 11 children nonspecific de/dysmyelination was detected. The brain tumor was detected in 6 children with symptomatic epilepsy. The most common disorder leading to epilepsy in children aged 3-18 years was encephalopathy, within hypoxic-ischemic encephalopathy. The other in sequence were malformations of nervous system and vascular diseases.

    Full Text Available Research on the antiepileptic effects of (endo-cannabinoids has remarkably progressed in the years following the discovery of fundamental role of the endocannabinoid (eCB system in controlling neural excitability. Moreover, an increasing number of well-documented cases of epilepsy patients exhibiting multi-drug resistance report beneficial effects of cannabis use. Pre-clinical and clinical research has increasingly focused on the antiepileptic effectiveness of exogenous administration of cannabinoids and/or pharmacologically induced increase of eCBs such as anandamide (also known as arachidonoylethanolamide [AEA]. Concomitant research has uncovered the contribution of neuroinflammatory processes and peripheral immunity to the onset and progression of epilepsy. Accordingly, modulation of inflammatory pathways such as cyclooxygenase-2 (COX-2 was pursued as alternative therapeutic strategy for epilepsy. Palmitoylethanolamide (PEA is an endogenous fatty acid amide related to the centrally and peripherally present eCB AEA, and is a naturally occurring nutrient that has long been recognized for its analgesic and anti-inflammatory properties. Neuroprotective and anti-hyperalgesic properties of PEA were evidenced in neurodegenerative diseases, and antiepileptic effects in pentylenetetrazol (PTZ, maximal electroshock (MES and amygdaloid kindling models of epileptic seizures. Moreover, numerous clinical trials in chronic pain revealed that PEA treatment is devoid of addiction potential, dose limiting side effects and psychoactive effects, rendering PEA an appealing candidate as antiepileptic compound or adjuvant. In the present study, we aimed at assessing antiepileptic properties of PEA in a mouse model of acute epileptic seizures induced by systemic administration of kainic acid (KA.

    Purpose To determine the incidence and classification of new-onset epilepsy, as well as the distribution of epilepsy syndromes in a population-based group of children, using the newly proposed Report of the ILAE Commission on Classification and Terminology 2005–2009. Methods We identified all children residing in Olmsted County, MN, 1 month through 17 years with newly diagnosed epilepsy from 1980–2004. For each patient, epilepsy was classified into mode of onset, etiology, and syndrome or constellation (if present). Incidence rates were calculated overall and also separately for categories of mode of onset and etiology. Results The adjusted incidence rate of new-onset epilepsy in children was 44.5 cases per 100,000 persons per year. Incidence rates were highest in the first year of life and diminished with age. Mode of onset was focal in 68%, generalized/bilateral in 23%, spasms in 3% and unknown in 5%. Approximately half of children had an unknown etiology for their epilepsy, and of the remainder, 78 (22%) were genetic and 101 (28%) were structural/metabolic. A specific epilepsy syndrome could be defined at initial diagnosis in 99/359 (28%) children, but only 9/359 (3%) had a defined constellation. Conclusion Nearly half of childhood epilepsy is of “unknown” etiology. While a small proportion of this group met criteria for a known epilepsy syndrome, 41% of all childhood epilepsy is of “unknown” cause with no clear syndrome identified. Further work is needed to define more specific etiologies for this group. PMID:21482075

  12. Academic achievement in children with epilepsy: a review.

    2011-11-01

    To examine published studies which have focussed on academic achievement in children with epilepsy with respect to prevalence rates of academic difficulties and possible correlates of academic achievement. This review examines studies which have focussed on prevalence rates of academic difficulties and correlates of academic achievement in children with epilepsy from 1990 to 2010. Prevalence rates of low academic achievement and academic underachievement are reported and correlates of academic achievement including seizure/epilepsy variables, demographic variables, and child/family variables are examined with respect to published studies. Published studies suggest that low academic achievement is more common than academic underachievement (achievement below that expected on basis of IQ scores) and it is not clear from published studies if rates of academic underachievement are significantly higher than in the general population. Clear patterns with regard to the identification of correlates of academic underachievement have not emerged although low achievement may be influenced in many cases by lower than average levels of cognitive functioning. Most studies have not focussed on the IQ-achievement discrepancy definitions of (specific) learning disability. Children with epilepsy who are experiencing academic difficulties may not qualify for formal educational supports to address these difficulties if eligibility criteria for such supports stress an IQ-achievement discrepancy.

    Background Phenobarbital is the first-line choice for neonatal seizures treatment, despite a response rate of approximately 45%. Failure to respond to acute anticonvulsants is associated with poor neurodevelopmental outcome, but knowledge on predictors of refractoriness is limited. Objective To quantify response rate to phenobarbital and to establish variables predictive of its lack of efficacy. Methods We retrospectively evaluated newborns with electrographically confirmed neonatal seizures admitted between January 1999 and December 2012 to the neonatal intensive care unit of Parma University Hospital (Italy), excluding neonates with status epilepticus. Response was categorized as complete (cessation of clinical and electrographic seizures after phenobarbital administration), partial (reduction but not cessation of electrographic seizures with the first bolus, response to the second bolus), or absent (no response after the second bolus). Multivariate analysis was used to identify independent predictors of refractoriness. Results Out of 91 newborns receiving phenobarbital, 57 (62.6%) responded completely, 15 (16.5%) partially, and 19 (20.9%) did not respond. Seizure type (p = 0.02), background electroencephalogram (EEG; p ≤ 0.005), and neurologic examination (p  ≤  0.005) correlated with response to phenobarbital. However, EEG (p  ≤  0.02) and seizure type (p  ≤  0.001) were the only independent predictors. Conclusion Our results suggest a prominent role of neurophysiological variables (background EEG and electrographic-only seizure type) in predicting the absence of response to phenobarbital in high-risk newborns.

    The effects of embelin (50 mg/kg/day), a benzoquinone derivative of Embelia ribes, and the effects of curcumin (100 mg/kg/day), the active principle of Curcuma longa, against N-nitrosodiethylamine (DENA)-initiated and phenobarbital (PB)-promoted hepatocarcinogenesis were studied in Wistar rats. They were able to prevent the induction of hepatic hyper plastic nodules, body weight loss, increase in the levels of hepatic diagnostic markers, and hypoproteinemia induced by DENA/PB treatment. Hence, results of our study suggest the possible chemopreventive effects of embelin (EMB) and curcumin (CUR) against DENA/PB-induced hepatocarcinogenesis in Wistar rats.

    Seizures are common in patients with brain tumors, and epilepsy can significantly impact patient quality of life. Therefore, a thorough understanding of rates and predictors of seizures, and the likelihood of seizure freedom after resection, is critical in the treatment of brain tumors. Among all tumor types, seizures are most common with glioneuronal tumors (70–80%), particularly in patients with frontotemporal or insular lesions. Seizures are also common in individuals with glioma, with the highest rates of epilepsy (60–75%) observed in patients with low-grade gliomas located in superficial cortical or insular regions. Approximately 20–50% of patients with meningioma and 20–35% of those with brain metastases also suffer from seizures. After tumor resection, approximately 60–90% are rendered seizure-free, with most favorable seizure outcomes seen in individuals with glioneuronal tumors. Gross total resection, earlier surgical therapy, and a lack of generalized seizures are common predictors of a favorable seizure outcome. With regard to anticonvulsant medication selection, evidence-based guidelines for the treatment of focal epilepsy should be followed, and individual patient factors should also be considered, including patient age, sex, organ dysfunction, comorbidity, or cotherapy. As concomitant chemotherapy commonly forms an essential part of glioma treatment, enzyme-inducing anticonvulsants should be avoided when possible. Seizure freedom is the ultimate goal in the treatment of brain tumor patients with epilepsy, given the adverse effects of seizures on quality of life. PMID:26948360

    Our objective was to compare the quality of life (QoL) of children with epilepsy to that of typical children and children with cerebral palsy (CP). We measured self- and proxy-reported QoL of children with epilepsy and contrasted that with data for typical children (European KIDSCREEN project) and children with CP (SPARCLE study). Children ages 8-12 years with epilepsy were recruited from six Canadian sites. Same-aged children with CP and children in the general population aged 8-11 years came from several European countries. All participants completed the KIDSCREEN-52 questionnaire. Our results showed no clinically important differences (>0.5 SD) between self-reported QoL in 345 children with epilepsy compared with 489 children with CP or 5950 children in the general population. However, parents reported clinically important differences between the epilepsy and the other groups in five KIDSCREEN-52 domains. Compared with the CP group, parents of children with epilepsy reported better QoL in physical well-being (Cohen d=0.81), social support (d=0.80), and autonomy (d=0.72). Parents reported poorer QoL in the domains of mood and emotions compared with both contrast groups (d=-0.72 and d=-0.53), and in the domain of bullying compared with the CP group (d=-0.51). Families should find comfort in the results, which indicate that children with epilepsy do not perceive any important differences in QoL compared with their typical peers. The comparisons of parental reports detect their group-specific observations and worries that need to be addressed by the health-care providers and may require specifically designed assessment batteries followed by appropriate interventions.

    This study examined the biochemical metabolism by proton magnetic resonance spectroscopy ('H-MRS) in order to explore the value of 'H-MRS in idiopathic epilepsy in children. Thirty-three children with idiopathic epilepsy (14 cases with history of febrile seizures and 19 cases without) and six normal controls experienced MRI of the skull and brain and single-voxel 'H-MRS examinations of the hippocampi-temporal lobe. The signal intensities of N-acetylaspartate (NAA), eatine+phosphocreatine (Cr), choline-containing compounds (Cho) and lactate (Lac) and the ratios of NAA/ (Cho+Cr) and Lac/Cr were compared between the patients and normal controls. MRI examination showed that only one child with epilepsy had myelin dysplasia. 'H-MRS examination showed that the ratio of NAA/ (Cho+Cr) in the epilepsy group was lower than that in the control group (0.64+/-0.07 vs 0.73+/-0.05; Pepilepsy and the control groups. 'H-MRS may provide early information on brain injury sensitively and non-invasively in children with epilepsy. It may be used for diagnosis and prognosis evaluation of epilepsy.

    Three recent publications have reported the development of erythema multiforme and Stevens-Johnson syndrome in patients receiving cranial irradiation and sodium phenytoin. Some authors have recommended that patients receiving whole brain radiation therapy and who have had seizures should not be prescribed phenytoin but an alternative anticonvulsant. This article reviews the current literature pertaining to the development of this potentially lethal complication in patients receiving whole brain radiation and phenytoin, with reference to the single recorded case of Stevens-Johnson syndrome in a patient receiving cranial irradiation and phenytoin in Auckland, New Zealand. While the clinical picture in the 16 patients reported in the literature and the current case report differed from the classical form of erythema multiforme, a similar pattern of presentation and outcome appeared in all patients reviewed, suggesting that the combination of phenytoin, cranial irradiation and the gradual reduction of concomitant steroids seem to lead to the development of erythema multiforme and/or Stevens-Johnson syndrome. The data presented, although sparse, suggest that phenytoin should not be prescribed in patients receiving cranial irradiation. 21 refs., 2 tabs., 3 figs.

    Neurocognitive impairment represents one of the most common comorbidities occurring in children with idiopathic epilepsy. Diagnosis of the idiopathic form of epilepsy requires the absence of any macrostructural abnormality in the conventional MRI. Though changes can be seen at the microstructural level imaged using advanced techniques such as the Diffusion Tensor Imaging (DTI). The aim of this work is to study the correlation between the microstructural white matter DTI findings, the electroencephalographic changes and the cognitive dysfunction in children with active idiopathic epilepsy. A comparative cross-sectional study, included 60 children with epilepsy based on the Stanford-Binet 5th Edition Scores was conducted. Patients were equally assigned to normal cognitive function or cognitive dysfunction groups. The history of the epileptic condition was gathered via personal interviews. All patients underwent brain Electroencephalography (EEG) and DTI, which was analyzed using FSL. The Fractional Anisotropy (FA) was significantly higher whereas the Mean Diffusivity (MD) was significantly lower in the normal cognitive function group than in the cognitive dysfunction group. This altered microstructure was related to the degree of the cognitive performance of the studied children with epilepsy. The microstructural alterations of the neural fibers in children with epilepsy and cognitive dysfunction were significantly related to the younger age of onset of epilepsy, the poor control of the clinical seizures, and the use of multiple antiepileptic medications. Children with epilepsy and normal cognitive functions differ in white matter integrity, measured using DTI, compared with children with cognitive dysfunction. These changes have important cognitive consequences. Copyright © 2018 Elsevier Inc. All rights reserved.

    To quantify the experience of discrimination, domestic violence, abuse, and other stressful life events in people with epilepsy in comparison with the general population and people with other chronic conditions. To assess whether any excess relative burden of these adversities could explain the higher rates of depression in people with epilepsy. The Adult Psychiatric Morbidity Survey 2007 used comprehensive interviews with 7,403 individuals living in private residences in England. Doctor-diagnosed epilepsy and other chronic conditions were established by self-report. Discrimination, domestic violence, physical and sexual abuse, and other stressful life events were assessed using computerized self-completion and a face-to-face interview, respectively. People with epilepsy were sevenfold more likely to have reported experiencing discrimination due to health problems (adjusted odds ratio [OR] 7.1; 95% confidence interval [CI] 3.1-16.3), than the general population without epilepsy. This estimate was substantially greater in people with epilepsy than for people with other chronic conditions. People with epilepsy also had greater odds of experiencing domestic violence and sexual abuse than the general population, although these associations were also found in people with other chronic conditions. There was less evidence of an association between epilepsy and a history of physical abuse or having a greater burden of other stressful life events. In exploratory analyses, assuming they lie on the causal pathway, discrimination, domestic violence, and sexual abuse explained 42.7% of the total effect of the relationship between epilepsy and depression or anxiety disorders. People with epilepsy can face a range of psychosocial adversities and extensively report feeling discriminated against as compared to the general population. In addition, if confirmed in longitudinal studies, the results suggest that these psychosocial adversities may have a significant role in the

    To validate a brief and reliable epilepsy-specific, health-related quality of life (HRQOL) measure in children with various seizure types, treatments, and demographic characteristics. This national validation study was conducted across five epilepsy centers in the United States. Youth 5-18 years and caregivers of youth 2-18 years diagnosed with epilepsy completed the PedsQL Epilepsy Module and additional questionnaires to establish reliability and validity of the epilepsy-specific HRQOL instrument. Demographic and medical data were collected through chart reviews. Factor analysis was conducted, and internal consistency (Cronbach's alphas), test-retest reliability, and construct validity were assessed. Questionnaires were analyzed from 430 children with epilepsy (M age = 9.9 years; range 2-18 years; 46% female; 62% white: non-Hispanic; 76% monotherapy, 54% active seizures) and their caregivers. The final PedsQL Epilepsy Module is a 29-item measure with five subscales (i.e., Impact, Cognitive, Sleep, Executive Functioning, and Mood/Behavior) with parallel child and caregiver reports. Internal consistency coefficients ranged from 0.70-0.94. Construct validity and convergence was demonstrated in several ways, including strong relationships with seizure outcomes, antiepileptic drug (AED) side effects, and well-established measures of executive, cognitive, and emotional/behavioral functioning. The PedsQL Epilepsy Module is a reliable measure of HRQOL with strong evidence of its validity across the epilepsy spectrum in both clinical and research settings.

    Full Text Available Erythrocytes may play a role in glucose homeostasis during the postprandial period. Erythrocytes from diabetic patients are defective in glucose transport and metabolism, functions that may affect glycogen storage. Phenobarbital, a hepatic enzyme inducer, has been used in the treatment of patients with non-insulin-dependent diabetes mellitus (NIDDM, increasing the insulin-mediated glucose disposal. We studied the effects of phenobarbital treatment in vivo on glycemia and erythrocyte glycogen content in control and alloxan-diabetic rats during the postprandial period. In control rats (blood glucose, 73 to 111 mg/dl in femoral and suprahepatic veins the erythrocyte glycogen content was 45.4 ± 1.1 and 39.1 ± 0.8 µg/g Hb (mean ± SEM, N = 4-6 in the femoral artery and vein, respectively, and 37.9 ± 1.1 in the portal vein and 47.5 ± 0.9 in the suprahepatic vein. Diabetic rats (blood glucose, 300-350 mg/dl presented low (P<0.05 erythrocyte glycogen content, i.e., 9.6 ± 0.1 and 7.1 ± 0.7 µg/g Hb in the femoral artery and vein, respectively, and 10.0 ± 0.7 and 10.7 ± 0.5 in the portal and suprahepatic veins, respectively. After 10 days of treatment, phenobarbital (0.5 mg/ml in the drinking water did not change blood glucose or erythrocyte glycogen content in control rats. In diabetic rats, however, it lowered (P<0.05 blood glucose in the femoral artery (from 305 ± 18 to 204 ± 45 mg/dl and femoral vein (from 300 ± 11 to 174 ± 48 mg/dl and suprahepatic vein (from 350 ± 10 to 174 ± 42 mg/dl, but the reduction was not sufficient for complete recovery. Phenobarbital also stimulated the glycogen synthesis, leading to a partial recovery of glycogen stores in erythrocytes. In treated rats, erythrocyte glycogen content increased to 20.7 ± 3.8 µg/g Hb in the femoral artery and 30.9 ± 0.9 µg/g Hb in the suprahepatic vein (P<0.05. These data indicate that phenobarbital activated some of the insulin-stimulated glucose metabolism steps which were

    A total of 132 women with epilepsy were confined in the period from 1978-1989. Their pregnancies and outcomes were analysed. The special aim was to find out if the anticonvulsive therapy has any correlation with the occurrence of fetal malformations in the studied group of women. In 43.9% of pregnant women with epilepsy, methyl-phenobarbitone as an anticonvulsive drug was administered, while carbamazepine was applied in 13.6% cases. A combination of phenytoin and phenobarbitone was prescribed in 18.9% of cases. Primidone was the drug of choice in 8% cases and 5.3% of patients were treated with various combinations of anticonvulsive drugs. Hyperemesis, threatened spontaneous abortion and premature labor complicated significantly more pregnancies in patients with epilepsy than on controls. Pregnancies from the studied group were terminated by the cesarean section in significantly more cases (11.2%) than in the control group (5.4%). Newborns from mothers with epilepsy had a statistically lower birthweight (3173 +/- 575 g) than those born from healthy mothers (3376 +/- 510g). Fifteen newborns or 11.2% were born with congenital malformations, while among the control group of newborns only two were malformed. It is noticed that the newborns from mothers treated with phenitoin and phenobarbitone had dysmorphic anomalies of the face more frequently. The drugs mentioned above interfere with the metabolism of K vitamin and as a result of this interreaction, mothers and newborns can suffer from coagulation disorders. In conclusion it is important to mention that no anticonvulsant drug seems to be absolutely safe when used during pregnancy since each of them has a teratogenic effect on the fetus.

    Full Text Available ABSTRACT This study aimed to obtain and characterize a microemulsion (ME containing phenobarbital (PB. The PB was incorporated in the proportion of 5% and 10% in a microemulsion system containing Labrasol(r, ethanol, isopropyl myristate and purified water. The physicochemical characterization was performed and the primary stability of the ME was evaluated. An analytical method was developed using spectrophotometry in UV = 242 nm. The kinetics of the in vitro release (Franz model of the ME and the emulsion (EM containing PB was evaluated. The incorporation of PB into ME at concentrations of 5 and 10% did not change pH and resistance to centrifugation. There was an increase in particle size, a decrease of conductivity and a change in the refractive index in relation to placebo ME. The ME remained stable in preliminary stability tests. The analytical method proved to be specific, linear, precise, accurate and robust. Regarding the kinetics of the in vitro release, ME obtained an in vitro release profile greater than the EM containing PB. Thus, the obtained ME has a potential for future transdermal application, being able to compose a drug delivery system for the treatment of epilepsy.

The typical clinical features of epilepsy are paroxysms and transient and stereotyped brain dysfunction. Many cases of epileptic seizures occurring during anesthesia have been reportedx. Recently, risk assessment of epileptic seizures during surgery and anesthesia has gained increasing attention. In this review, we systematically summarize the influence of anesthesia on epileptic seizures; the types, durations and frequencies of seizures related to anesthesia; and the epidemiology, prevention, treatment and prognosis of epilepsy. We also explore the possible mechanism of epilepsy and provide guidance for anesthesia during surgeries.

    The aim of this study was to validate the newly developed shortened Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) in a sample of children with drug-resistant epilepsy. Data came from 136 children enrolled in the Impact of Pediatric Epilepsy Surgery on Health-Related Quality of Life Study (PEPSQOL), a multicenter prospective cohort study. Confirmatory factor analysis was used to assess the higher-order factor structure of the QOLCE-55. Convergent and divergent validity was assessed by correlating subscales of the KIDSCREEN-27 with the QOLCE-55. Measurement equivalence of the QOLCE-55 was evaluated using multiple-group confirmatory factor analysis of children with drug-resistant epilepsy from PEPSQOL versus children with new-onset epilepsy from HERQULES (Health-Related Quality of Life in Children with Epilepsy Study). The higher-order factor structure of the QOLCE-55 demonstrated adequate fit: Comparative Fit Index (CFI) = 0.948; Tucker-Lewis Index (TLI) = 0.946; Root Mean Square of Approximation (RMSEA) = 0.060 (90% confidence interval [CI] 0.054-0.065); Weighted Root Mean Square Residuals (WRMR) = 1.247. Higher-order factor loadings were strong, ranging from λ = 0.74 to 0.81. Internal consistency reliability was excellent (α = 0.97, subscales α > 0.82). QOLCE-55 subscales demonstrated moderate to strong correlations with similar subscales of the KIDSCREEN-27 (ρ = 0.43-0.75) and weak to moderate correlations with dissimilar subscales (ρ = 0.25-0.42). The QOLCE-55 demonstrated partial measurement equivalence at the level of strict invariance - χ 2 (2,823) = 3,727.9, CFI = 0.961, TLI = 0.962, RMSEA = 0.049 (0.044, 0.053), WRMR = 1.834. The findings provide support for the factor structure of the QOLCE-55 and contribute to its robust psychometric profile as a reliable and valid measure. Researchers and health practitioners should consider the QOLCE-55 as a viable option for reducing respondent burden when assessing health-related quality of life

    The use of antiepileptic drugs (AEDs) in the neurosurgical setting has a number of implications, including their possible role in the prevention of seizures after acute cerebral insults or brain tumors and the potential for toxicity and interactions when these agents are administered in association with radiotherapy or chemotherapy. This review discusses these controversial issues and draws the following conclusions. 1) AEDs should be prescribed on a short-term basis to prevent seizures occurring within the first week after a cerebral insult (trauma, neurosurgical procedure) but are ineffective to avoid true post-traumatic epilepsy or first seizures in patients with primary or secondary cerebral neoplasms. 2) The use of phenytoin and, to a lesser extent, phenobarbital and carbamazepine during cranial irradiation is associated with an increased risk for severe, potentially fatal, mucocutaneous reactions. In this context, new AEDs with a very low potential for allergic cutaneous reactions should be preferred. 3) Enzyme-inducing AEDs, such as phenytoin, phenobarbital, and carbamazepine, may increase the clearance and reduce the clinical efficacy of corticosteroids and anticancer agents that are also metabolized by the cytochrome P450 system. The newly developed AEDs that are devoid of hepatic metabolism, such as levetiracetam and gabapentin, are now recommended because of good results in preliminary studies and because they do not show interactions with anticancer agents.

    The purpose of this study was to verify effects of the Empowering A Self-Efficacy (EASE) program on self-efficacy, self-management, and child attitude toward illness in children with epilepsy. This was a quasi-experimental study with a non-equivalent control group pre-post test design. Participants were 10 to 15 year old children with epilepsy (11 in the experimental group and 10 in the control group) who were registered at one hospital in S city. The experimental group received the EASE program for 3 weeks. In the first week, a group meeting lasting 570 minutes was conducted on a single day. Over the next two weeks, telephone counselling was conducted twice a week. Data were analyzed using SPSS 18.0. There was a significant difference of pre-post evaluation of the epilepsy self-management scores in the experimental group. However, differences between the experimental group and the control group for seizure self-efficacy and child attitude toward illness were not significant. This is the first study in Korea to develop and evaluate an intervention program for children with epilepsy. Further studies are needed to confirm the effects of the EASE program.

    The characteristics of some population groups (patients with comorbidities, women of childbearing age, the elderly) may limit epilepsy management. Antiepileptic treatment in these patients may require adjustments. We searched articles in Pubmed, clinical practice guidelines for epilepsy, and recommendations by the most relevant medical societies regarding epilepsy in special situations (patients with comorbidities, women of childbearing age, the elderly). Evidence and recommendations are classified according to the prognostic criteria of Oxford Centre of Evidence-Based Medicine (2001) and the European Federation of Neurological Societies (2004) for therapeutic interventions. Epilepsy treatment in special cases of comorbidities must be selected properly to improve efficacy with the fewest side effects. Adjusting antiepileptic medication and/or hormone therapy is necessary for proper seizure management in catamenial epilepsy. Exposure to antiepileptic drugs (AED) during pregnancy increases the risk of birth defects and may affect fetal growth and/or cognitive development. Postpartum breastfeeding is recommended, with monitoring for adverse effects if sedative AEDs are used. Finally, the elderly are prone to epilepsy, and diagnostic and treatment characteristics in this group differ from those of other age groups. Although therapeutic limitations may be more frequent in older patients due to comorbidities, they usually respond better to lower doses of AEDs than do other age groups.

    Full Text Available Background Infantile spasms (IS is an age-spedfic epilepsy syndrome characterized by flexor, extensor, and mixed flexor-extensor spasms which often occur in clusters during the first 2 years of life. IS is often difficult to manage 'With the usual anti-epilepsy drugs (AEDs. Therapy with adrenocorticotropin honnone (ACTH has been used since 1958. In Indonesia, ACTH usage is still rare. Objective This study aims to examine the effectiveness of ACTH as an anti-epileptic drug in managing IS. Methods This was descriptive retrospective cohort study. Subjects were IS patients who visited the neurology outpatient clinic in Sanglah Hospital, Bali, from January 2007 until June 2010. Each subject received AED(s plus either ACTH or methylprednisolone for 46 weeks. Results There were 19 IS patients over the four year duration of this study. They were mostly boys (11, aged 2 weeks to 17 months, with a mean age at treatment of 9 months. Eighteen patients received poly therapy, while one patient received only phenobarbital as monotherapy. Most patients who received ACTH (13/16 had a seizure-free period, while the 3 that did not receive ACTH continued having seizures. Patients who received ACTH showed a good response (seizure-free after 5-13 days therapy and their EEG pattern showed disappearance of burst suppression Mthin 1-2 weeks. ACTH side effects included weight gain and cushingoid appearance. One patient died from pneumonia. Conclusions Diagnosis of IS should be considered in patients pre-senting Mth spasms at less than 6 months old. IS treatment should begin as soon as possible. IS patients responded well to a short course of ACTH therapy.

    A suppository for rectal administration of carbamazepine has been developed for situations in which it is unsuitable to use the oral route of administration. In an open, controlled, within-patient study, the pharmacokinetics, clinical efficacy, and tolerability of carbamazepine slow-release tablets were compared with those of carbamazepine suppositories in children with epilepsy. The pharmacokinetic part of the study comprised 22 children, and an additional nine children were included in the clinical part of the study. Treatment with slow-release tablets was replaced for 7 days with carbamazepine suppositories in bioequivalent dosage. Clinical factors such as the rate of seizures and the local tolerability were studied, and an overall assessment of efficacy was made. In the pharmacokinetic part, 24-hour plasma concentration curves for carbamazepine and carbamazepine-10,11-epoxide were recorded. The plasma concentration profiles (minimum, maximum, and mean concentrations, fluctuation index, and area under the curve) for carbamazepine and the other metabolites did not show any significant differences between oral and rectal administration when the suppository dose was increased by 25% compared to the tablets. No increase in seizure frequency was detected, and the overall assessment was very good to good in 25 of the 29 epileptic children. Increased flatulence during treatment with suppositories was noted in two children, one had anal irritation, and one had nausea/vomiting. Treatment with carbamazepine slow-release tablets in children with epilepsy can be replaced by carbamazepine suppositories in 25% higher dosage, with good clinical effect and appropriate pharmacokinetic values, when it is unsuitable to use the common oral route of administration.

    The current study sought to understand the contribution of the attention and working memory challenges experienced by children with active epilepsy without an intellectual disability to adaptive functioning (AF) while taking into account intellectual ability, co-occurring brain-based psychosocial diagnoses, and epilepsy-related variables. The relationship of attention and working memory with AF was examined in 76 children with active epilepsy with intellectual ability above the 2nd percentile recruited from a tertiary care center. AF was measured using the Scales of Independent Behavior-Revised (SIB-R) and compared with norm-referenced data. Standardized clinical assessments of attention span, sustained attention, as well as basic and more complex working memory were administered to children. Commonality analysis was used to investigate the importance of the variables with respect to the prediction of AF and to construct parsimonious models to elucidate the factors most important in explaining AF. Seventy-one percent of parents reported that their child experienced mild to severe difficulties with overall AF. Similar proportions of children displayed limitations in domain-specific areas of AF (Motor, Social/Communication, Person Living, and Community Living). The reduced models for Broad and domain-specific AF produced a maximum of seven predictor variables, with little loss in overall explained variance compared to the full models. Intellectual ability was a powerful predictor of Broad and domain-specific AF. Complex working memory was the only other cognitive predictor retained in each of the parsimonious models of AF. Sustained attention and complex working memory explained a large amount of the total variance in Motor AF. Children with a previously diagnosed comorbidity displayed lower Social/Communication, Personal Living, and Broad AF than those without a diagnosis. At least one epilepsy-related variable appeared in each of the reduced models, with age of

    Full Text Available BackgroundRecent studies on pharmacoresponsive epilepsies demonstrate specific memory, executive functions (EF, and psychosocial deficits in this group. These deficits are often undertreated, and little is known about the neuropsychological factors that may support moderation of the deficits through intervention. The aim of this study was to explore the effects of a structured cognitive behavioral group intervention on both memory and emotional domains and to evaluate the factors influencing its efficacy.MethodsThe feasibility study implemented a newly designed intervention for children with pharmacoresponsive epilepsies (N = 33, aged 9–14 years, 51% girls, hypothesizing that memory and psychosocial symptoms in children with pharmacoresponsive epilepsies are sensitive to intervention using structured memory and psychosocial modules in a weekly group session setting. Comparable memory and psychosocial assessments were used to evaluate performance at baseline and post-intervention. Results were compared to age- and education-matched healthy controls (N = 27, aged 9–14 years.ResultsPre–post-intervention comparisons show improvements in STM (p < 0.01, η2 = 0.358, optimism (p < 0.05, η2 = 0.245, and self-efficacy (p < 0.05, η2 = 0.164. Unique negative relations between memory deficits and psychosocial phenotype were seen in epilepsy patients and not in controls in response to the intervention. EF moderated this intervention effect (p < 0.05, η2 = 0.252, whereas psychosocial status and pharmacological profile did not.ConclusionCognitive behavioral therapy focusing on memory and psychosocial perceptions for children with pharmacoresponsive epilepsies seems promising, with greater improvement in memory and psychosocial functioning in children with more affected EF.

    To obtain perspective on epilepsy in patients referred to tertiary centers in France, and describe etiology, epilepsy syndromes, and identify factors of drug resistance and comorbidities. We performed a cross-sectional analysis of the characteristics of 5,794 pediatric and adult patients with epilepsy included in a collaborative database in France between 2007 and 2013. Comparisons between groups used Student's t-test or Fisher's exact test for binary or categorical variables. Factors associated with drug resistance and intellectual disability were evaluated in multi-adjusted logistic regression models. Mean age at inclusion was 17.9 years; children accounted for 67%. Epilepsy was unclassified in 20% of patients, and etiology was unknown in 65%, including those with idiopathic epilepsies. Etiologies differed significantly in adult- when compared to pediatric-onset epilepsy; however, among focal structural epilepsies, mesial temporal lobe epilepsy with hippocampal sclerosis began as often in the pediatric as in adult age range. Drug resistance concerned 53% of 4,210 patients evaluable for seizure control and was highest in progressive myoclonic epilepsy (89%), metabolic diseases (84%), focal cortical dysplasia (70%), other cortical malformations (69%), and mesial temporal lobe epilepsy with hippocampal sclerosis (67%). Fifty-nine percent of patients with focal structural epilepsy and 69% with epileptic encephalopathies were drug resistant; however, 40-50% of patients with West syndrome and epileptic encephalopathy with continuous spike-and-waves during sleep were seizure-free. Ages at onset in infancy and in young adults shared the highest risk of drug resistance. Epilepsy onset in infancy comprised the highest risk of intellectual disability, whereas specific cognitive impairment affected 36% of children with idiopathic focal epilepsy. Our study provides a snapshot on epilepsy in patients referred to tertiary centers and discloses needs for diagnosis and treatment

    We aimed to determine the midterm effect of a ketogenic diet on serum lipid levels, carotid intima-media thickness, and the elastic properties of the carotid artery and the aorta in patients with intractable epilepsy. A total of 52 children aged between 12 months and 18 years with intractable epilepsy who started the ketogenic diet from September 2014 to September 2015 were included into this prospective study. Carotid intima-media thickness and the elastic properties of the carotid artery and the aorta were assessed by echocardiography in all cases before beginning of the ketogenic diet and after at least 12 months on the ketogenic diet. Twenty-one patients at the third month and 25 patients at the first year of the ketogenic diet were seizure free. A reduction of greater than 90% in the seizure frequency was achieved in three patients at the sixth month and in five patients at the first year of the treatment. The serum levels of total cholesterol, low-density lipoprotein, and triglyceride were increased significantly at a median of 12.6 months (range: 12 to 13.5 months) of the ketogenic diet treatment, whereas serum levels of high-density lipoprotein did not change. Carotid intima-media thickness, aortic and carotid strain, the stiffness index, distensibility, and elastic modulus did not change after 12 months of the ketogenic diet therapy. Olive oil-based ketogenic diet appears to have no disturbing effect on the carotid intima-media thickness and the elastic properties of the aorta and the carotid artery in epileptic children, although it may be associated with increased concentrations of serum lipids.

    Little is known about subgroups of children with epilepsy who may experience less favorable outcomes over time. The objectives of this study were to document trajectories of health-related quality of life (HRQL) and to identify predictors of the trajectory group in children with new-onset epilepsy. Data were obtained from the Health Related Quality of Life in Children with Epilepsy Study, a prospective multisite study of children 4-12 years old with new-onset epilepsy followed for 24 months. Health-related quality of life was measured using the Quality of Life in Childhood Epilepsy questionnaire. Trajectories of HRQL were investigated using latent class trajectory modeling. Multinomial logistic regression was used to identify child, parent, and family predictors of HRQL trajectories. A total of 374 families responded at baseline and 283 (76%) completed the study. Five HRQL trajectories were observed: low-increasing (4%), moderate-decreasing (12%), moderate-increasing (22%), high-increasing (32%), and high-stable (30%). Many children in the low-increasing, moderate-increasing, high-increasing, and high-stable had clinically meaningful improvements in HRQL: 82%, 47%, 63%, and 44%, respectively. In contrast, the majority of children in the moderate-decreasing group (56%) experienced clinically meaningful declines in their HRQL. Factors predicting trajectories were number of antiepileptic drugs prescribed, presence of comorbid behavior or cognitive problems, parent depression, and family functioning and demands. Results suggested that children with epilepsy are not homogenous but rather consist of groups with different trajectories and unique predictors of HRQL. Problems associated with child behavior and cognition were the strongest predictors identified. Given that several risk factors are modifiable, it is important to examine these as potential targets within a family-centered framework to improve HRQL of children with new-onset epilepsy.

    Adherence to medication regimens is a crucial factor in seizure-freedom and well-being for people with epilepsy. In contrast, taking medication inconsistently increases the risk of not only seizures and their adverse effects, but drug side-effects and unnecessary modifications to treatment plans. Epilepsy is prevalent across all age groups and we have been slow to utilise both the technologies and psychologies derived from computer gaming. Gaming has broken through to the mainstream and is no longer the preserve of younger males, mirroring the adoption of smart-phones. 'Gamification' motivates users into engaging in an activity with a higher intensity and duration. Introducing gaming elements into a non-gaming context has the potential to transform routine tasks into more enjoyable and motivating experiences. This has been exploited by marketing executives, but also has clear uses in a healthcare setting too. We discuss how previously published frameworks could be employed to help people with epilepsy adhere to medication regimens to create a patient-focussed, modifiable and fun experience.

    We conducted the present study to examine cognitive function and serum heat shock protein 70 levels among children with temporal lobe epilepsy. The Stanford-Binet Intelligence Test was carried out to examine cognitive function in 30 children with temporal lobe epilepsy and 30 controls. Serum heat shock protein 70 levels were determined with an enzyme-linked immunosorbent assay. The epilepsy group had significantly lower cognitive function testing scores and significantly higher serum heat shock protein 70 levels than the control group; there were significant negative correlations between serum heat shock protein 70 levels and short-term memory and composite scores. Children with uncontrolled seizures had significantly lower verbal reasoning scores and significantly higher serum heat shock protein 70 levels than children with controlled seizures. Children with temporal lobe epilepsy have cognitive dysfunction and elevated levels of serum heat shock protein 70, which may be considered a stress biomarker.

    Idiopathic epilepsies are considered to have relatively good prognoses and normal or near normal developmental outcomes. Nevertheless, accumulating studies demonstrate memory and psychosocial deficits in this population, and the prevalence, severity and relationships between these domains are still not well defined. We aimed to assess memory, psychosocial function, and the relationships between these two domains among children with idiopathic epilepsy syndromes using an extended neuropsychological battery and psychosocial questionnaires. Cognitive abilities, neuropsychological performance, and socioemotional behavior of 33 early adolescent children, diagnosed with idiopathic epilepsy, ages 9-14years, were assessed and compared with 27 age- and education-matched healthy controls. Compared to controls, patients with stabilized idiopathic epilepsy exhibited higher risks for short-term memory deficits (auditory verbal and visual) (pmemory deficits (plong-term memory deficits (pmemory deficits was related to severity of psychosocial symptoms among the children with epilepsy but not in the healthy controls. Results suggest that deficient auditory verbal memory may be compromising psychosocial functioning in children with idiopathic epilepsy, possibly underscoring that cognitive variables, such as auditory verbal memory, should be assessed and treated in this population to prevent secondary symptoms.

    The ketogenic diet, a non-drug treatment with proven effectiveness, has been the most commonly used therapy in the past decade for the management of refractory epilepsy in the pediatric population. Compared to adding a new drug to a pre-existing treatment, the ketogenic diet is highly effective and reduces the number of seizures by 50-90% in approximately 45-60% of children after six months of treatment. For this reason, the Argentine Society of Pediatric Neurology established the Ketogenic Diet Working Group. It is integrated by pediatric dietitians, pediatricians, pediatric neurologists and B.S. in Nutrition, who developed recommendations for the optimal management of patients receiving the classical ketogenic diet based on expert consensus and scientific publications in this field.

    Partial epilepsy is a very important problem of epileptology in childhood including clinical and therapeutic aspect especially surgery treatment. The aim of this study is to assess clinical value of neuroimagine techniques (structural MRI, MRI angiography) in partial epilepsy diagnostics in children. The relation between results of examinations with these methods and congenital and acquired risk factors related to partial epilepsy, age of its onset and clinical assessment of patients was analyzed. The study group consisted of 140 children with partial epilepsy hospitalized between 1998 and 2004 in Department of Pediatric Neurology, Collegium Medicum Jagiellonian University, Krakow. The group included 70 girls and 70 boys, the age ranged from 2 months to 17 years. In study group statistical analysis included different factors as which can be related with results of neuroimaging as age, load of pregnancy and birth period, familiar epilepsy, patient's risk factors for appearance of epilepsy, acquired risk factors of epilepsy, results of neurological examination, type of epilepsy, status epilepticus, and signs according epileptic attacks which can be related with neuroimaging results. The primary method of neuroimagine in all patients was structural MRI, in 16 cases Magnetic Resonance Angiography (MRA). The parametric tests (t-student), nonparametric Mann-Whitney's test were used in statistical analysis. The bilateral Fisher test was used to check rate in groups. There was assessed sensitivity, specificity, positive predictive value, negative predictive value; the 95% confidence interval was calculated for these parameters. Abnormalities in neurological examination in children with partial epilepsy were strongly correlated with MRI findings. The structural changes in MRI were found in younger children, whose course of epilepsy was longer than children without MRI changes. Changes in hippocampus ere the most common in children with partial epilepsy with abnormalities in

    Acute intermittent porphyria (AIP) is a genetic disorder caused by a deficiency of porphobilinogen deaminase (PBGD), the 3rd enzyme in heme synthesis. It is clinically characterized by acute attacks of neuropsychiatric symptoms and biochemically by increased urinary excretion of the porphyrin precursors porphobilinogen (PBG) and 5-aminolevulinic acid (ALA). A mouse model that is partially deficient in PBGD and biochemically mimics AIP after induction of the hepatic ALA synthase by phenobarbital was used in this study to identify the site of formation of the presumably toxic porphyrin precursors and study the effect of enzyme-replacement therapy by using recombinant human PBGD (rhPBGD). After 4 d of phenobarbital administration, high levels of PBG and ALA were found in liver, kidney, plasma, and urine of the PBGD-deficient mice. The administration of rhPBGD intravenously or subcutaneously after a 4-d phenobarbital induction was shown to lower the PBG level in plasma in a dose-dependent manner with maximal effect seen after 30 min and 2 h, respectively. Injection of rhPBGD subcutaneously twice daily during a 4-d phenobarbital induction reduced urinary PBG excretion to 25% of the levels found in PBGD-deficient mice administered with only phenobarbital. This study points to the liver as the main producer of PBG and ALA in the phenobarbital-induced PBGD-deficient mice and demonstrates efficient removal of accumulated PBG in plasma and urine by enzyme-replacement therapy.

Four (ID 1-4 were used for the 10 mg/kg IV TPM + PO TPM study, and three (ID 3-5 were used for the 20 mg/kg IV TPM study. IV TPM was infused over 5 minutes at both doses. The animals were observed for vomiting, diarrhea, ataxia, and lethargy. Blood samples were collected at scheduled pre- and post-dose times. Plasma concentrations were measured using a validated HPLC-MS method. Non-compartmental and population compartmental modeling were performed (Phoenix WinNonLin and NLME using plasma concentrations from all dogs in the study. Intracranial EEG (iEEG was acquired in one dog. The difference between averaged iEEG energy levels at 15 minutes pre- and post-dose was assessed using a Kruskal-Wallis test. No adverse events were noted. Topiramate concentration-time profiles were best fit by a two-compartment model. PB co-administration was associated with a 5.6 fold greater clearance and a ~4 fold shorter elimination half-life. iEEG data showed that TPM produced a significant energy increase at frequencies >4 Hz across all 16 electrodes within 15 minutes of dosing. Simulations suggested that dogs on an enzyme inducer would require 25 mg/kg, while dogs on non-inducing drugs would need 20 mg/kg to attain the target concentration (20-30 µg/mL at 30-minutes post-dose.This study shows that IV

    The nuclear receptors CAR (constitutive androstane receptor) and PXR (pregnane X receptor) mediate the effects of phenobarbital on gene transcription. To investigate the relative contribution of these nuclear receptors to the expression of specific genes we studied the effect of phenobarbital in livers of wild type, CAR(-/-), PXR(-/-) and CAR/PXR(-/-) knockout mice. Spotted Steroltalk v1 cDNA arrays were applied containing probes for genes involved in drug metabolism, sterol biosynthesis, steroid synthesis/transport and heme synthesis. In the absence of CAR and PXR, phenobarbital unexpectedly induced mRNAs of several nuclear receptors, including PPARalpha and its target genes Cyp4a10 and Cyp4a14. Interestingly, in primary cultures of hepatocytes isolated from CAR/PXR(-/-) knockout mice, phenobarbital increased HNF-4alpha levels. In further experiments in these hepatocyte cultures we provide evidence that phenobarbital directly induces transcription of the PPARalpha gene via its HNF-4alpha response element, and indirectly by lack of inhibitory crosstalk of AMPK, CAR and PXR with HNF-4alpha. Our results provide further insight into CAR and PXR-independent effects of phenobarbital and the crosstalk between different nuclear receptor signaling pathways.

    The role of resective surgery in the treatment of polymicrogyria (PMG)-related focal epilepsy is uncertain. Our aim was to retrospectively evaluate the seizure outcome in a consecutive series of patients with PMG-related epilepsy who received, or did not receive, surgical treatment, and to outline the clinical characteristics of patients who underwent surgery. We evaluated 64 patients with epilepsy associated with magnetic resonance imaging (MRI)-documented PMG. After presurgical evaluation, 32 patients were excluded from surgical treatment and 32 were offered surgery, which was declined by 8 patients. Seizure outcome was assessed in the 40 nonsurgical and 24 surgical patients. Of 40 nonsurgical patients, 8 (20%) were seizure-free after a mean follow-up of 91.7 ± (standard deviation) 59.5 months. None of the eight patients who declined surgical treatment was seizure-free (mean follow-up: 74.3 ± 60.6 months). These seizure outcomes differ significantly (p = 0.000005 and p = 0.0003, respectively) from that of the 24 surgical patients, 18 of whom (66.7%) were Engel's class I postoperatively (mean follow-up: 66.5 ± 54.0 months). Of the eight patients excluded from surgery for seizure control at first visit, two had seizure recurrence at last contact. At last contact, antiepileptic drugs (AEDs) had been withdrawn in 6 of 24 surgical and in one of 40 nonsurgical cases (p = 0.0092). The present study indicates that, at least in a subset of adequately selected patients with PMG-related epilepsy, surgery may provide excellent seizure outcomes. Furthermore, it suggests that surgery is superior to AEDs for achieving seizure freedom in these cases. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    children affected by refractory epilepsy could be at risk of malnutrition because of feeding difficulties (anorexia, chewing, swallowing difficulties or vomiting) and chronic use of anticonvulsants, which may affect food intake and energy metabolism. Moreover, their energy requirement may be changed as their disabilities would impede normal daily activities. The aim of the present study was to evaluate nutritional status, energy metabolism and food intake in children with refractory epilepsy. 17 children with refractory epilepsy (13 boys and 4 girls; mean age 9 +/- 3,2 years; Body Mass Index 15,7 +/- 3,6) underwent an anthropometric assessment, body composition evaluation by dual-energy X-ray absorptiometry, detailed dietetic survey and measurement of resting energy expenditure by indirect calorimetry. Weight-for-age, height-for-age (stunting) and weight-for-height (wasting) were estimated compared to those of a reference population of the same age. 40% of children were malnourished and 24% were wasted. The nutritional status was worse in the more disabled children. Dietary intake resulted unbalanced (18%, 39%, 43% of total daily energy intake derived respectively from protein, lipid and carbohydrate). Adequacy index [nutrient daily intake/recommended allowance (RDA) x 100] was nutritional assessment and management as part of their overall care.

    Full Text Available Introduction: Epilepsy is a common disorder worldwide, commonly starting during childhood. Despite the high impact of psychiatric comorbidities in these patients, little is known about Iranian children with epilepsy. Methods: This cross sectional study was carried out in the tertiary clinics of the Tabriz University of Medical Sciences, Tabriz, Iran. All of the children (aged between 6 and 18 with a diagnosis of epilepsy were enrolled in this study. A semi-structured psychiatric interview was carried out using the Farsi (Persian version of the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL. Results: From a total of 298 participants, 270 (90.6% completed the process, including 120 (44.4% girls and 150 (55.6% boys. At least one psychiatric diagnosis was made in 222 (82.2% patients. The most prevalent psychiatric disorders in children and adolescents with epilepsy were attention deficit/hyperactivity disorder (34.4%, major depressive disorder (MDD (29.6%, social phobia (14.8% and oppositional defiant disorder (ODD (14.8%. Agoraphobia and anorexia nervosa were significantly more prevalent among girls. The following disorders were more prevalent in children aged between 13 and 18: MDD (47.5%, psychotic disorder (2.5%, social phobia (23.7%, generalized anxiety disorder (GAD (15.3%, conduct disorder (13.6%, chronic motor tic disorder (13.6% and substance related disorders (4.8%. Separation anxiety (15.1% and enuresis (1.5%, on the other hand, were more prevalent among younger children. A logistic regression model showed that psychiatric disorders in parents or siblings could independently predict at least one psychiatric comorbidity in children with epilepsy.Conclusion: Iranian children with epilepsy face a high burden of psychiatric and behavioral comorbidities compared to same aged general population that should be considered for comprehensive care.
