Summary of recommendations for the management of infantile seizures: Task Force Report for the ILAE Commission of Pediatrics.

Evidence-based guidelines, or recommendations, for the management of infants with seizures are lacking. A Task Force of the Commission of Pediatrics developed a consensus document addressing diagnostic markers, management interventions, and outcome measures for infants with seizures. Levels of evidence to support recommendations and statements were assessed using the American Academy of Neurology Guidelines and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The report contains recommendations for different levels of care, noting which would be regarded as standard care, compared to optimal care, or "state of the art" interventions. The incidence of epilepsy in the infantile period is the highest of all age groups (strong evidence), with epileptic spasms the largest single subgroup and, in the first 2 years of life, febrile seizures are the most commonly occurring seizures. Acute intervention at the time of a febrile seizure does not alter the risk for subsequent epilepsy (class 1 evidence). The use of antipyretic agents does not alter the recurrence rate (class 1 evidence), and there is no evidence to support initiation of regular antiepileptic drugs for simple febrile seizures (class 1 evidence). Infants with abnormal movements whose routine electroencephalography (EEG) study is not diagnostic, would benefit from video-EEG analysis, or home video to capture events (expert opinion, level U recommendation). Neuroimaging is recommended at all levels of care for infants presenting with epilepsy, with magnetic resonance imaging (MRI) recommended as the standard investigation at tertiary level (level A recommendation). Genetic screening should not be undertaken at primary or secondary level care (expert opinion). Standard care should permit genetic counseling by trained personal at all levels of care (expert opinion). Genetic evaluation for Dravet syndrome, and other infantile-onset epileptic encephalopathies, should be available in tertiary care (weak evidence, level C recommendation). Patients should be referred from primary or secondary to tertiary level care after failure of one antiepileptic drug (standard care) and optimal care equates to referral of all infants after presentation with a seizure (expert opinion, level U evidence). Infants with recurrent seizures warrant urgent assessment for initiation of antiepileptic drugs (expert opinion, level U recommendation). Infantile encephalopathies should have rapid introduction and increment of antiepileptic drug dosage (expert opinion, level U recommendation). There is no high level evidence to support any particular current agents for use in infants with seizures. For focal seizures, levetiracetam is effective (strong evidence); for generalized seizures, weak evidence supports levetiracetam, valproate, lamotrigine, topiramate, and clobazam; for Dravet syndrome, strong evidence supports that stiripentol is effective (in combination with valproate and clobazam), whereas weak evidence supports that topiramate, zonisamide, valproate, bromide, and the ketogenic diet are possibly effective; and for Ohtahara syndrome, there is weak evidence that most antiepileptic drugs are poorly effective. For epileptic spasms, clinical suspicion remains central to the diagnosis and is supported by EEG, which ideally is prolonged (level C recommendation). Adrenocorticotropic hormone (ACTH) is preferred for short-term control of epileptic spasms (level B recommendation), oral steroids are probably effective in short-term control of spasms (level C recommendation), and a shorter interval from the onset of spasms to treatment initiation may improve long-term neurodevelopmental outcome (level C recommendation). The ketogenic diet is the treatment of choice for epilepsy related to glucose transporter 1 deficiency syndrome and pyruvate dehydrogenase deficiency (expert opinion, level U recommendation). The identification of patients as potential candidates for epilepsy surgery should be part of standard practice at primary and secondary level care. Tertiary care facilities with experience in epilepsy surgery should undertake the screening for epilepsy surgical candidates (level U recommendation). There is insufficient evidence to conclude if there is benefit from vagus nerve stimulation (level U recommendation). The key recommendations are summarized into an executive summary. The full report is available as Supporting Information. This report provides a comprehensive foundation of an approach to infants with seizures, while identifying where there are inadequate data to support recommended practice, and where further data collection is needed to address these deficits.

Mutations in NHLRC1 cause progressive myoclonus epilepsy.

Lafora progressive myoclonus epilepsy is characterized by pathognomonic endoplasmic reticulum (ER)-associated polyglucosan accumulations. We previously discovered that mutations in EPM2A cause Lafora disease. Here, we identify a second gene associated with this disease, NHLRC1 (also called EPM2B), which encodes malin, a putative E3 ubiquitin ligase with a RING finger domain and six NHL motifs. Laforin and malin colocalize to the ER, suggesting they operate in a related pathway protecting against polyglucosan accumulation and epilepsy.

The miracle of the black leg: E astern neglect of Western addition to the hagiography of Saints Cosmas and Damian.

The Christian miracle tales strongly support the identification of Sts. Cosmas and Damian as doctors. The most famous of the saints' posthumous miracles, is that of the Black Leg. The main source of this story is the Golden Legend by Jacobus da Varagine, collection of fanciful hagiographies compiled in the 13th century. Saints Cosmas and Damian miraculously transplanted the black leg of the Ethiopian man onto the white body of the verger with "cancerous" leg. Saints appeared to the patient in a dream, amputated his diseased leg and replaced it with the leg of a recently died man. This dramatic cure was attractive for many western artists. The iconography of this miracle was depicted for the first time in a Florentine panel of ca.1370. The color of the leg later attracted special attention. Since the 1990's the Miracle of the Black Leg, presented in a (neo) Byzantine style, appeared in Greece. The miracle of Holy Unmercenaries has no proper historical foundation in the Books of the lives of the Saints in the Orthodox Churches. Action focused on replacement of the affected leg with one from cadaveric donor was unknown to the eastern Christianity. Exploration of available orthodox hagiographical sources related to the healing powers of Sts. Cosmas and Damian showed remarkable neglect of that miracle. Some contemporary Greek authors find appropriate to disregard it.

L-2-Hydroxyglutaric aciduria: a case report.

INTRODUCTION: L-2-Hydroxyglutaric aciduria (L-2-HGA) is an autosomal recessive neurometabolic disease with a slowly progressive course and characterized by increased levels of hydroxyglutaric acid in urine, cerebrospinal fluid and plasma. In this condition clinical features mainly consist of mental deterioration, ataxia and motor deficits. CASE OUTLINE: The patient is a 16-year-old girl, the first and only child of healthy, non-consanguineous parents of Serbian origin. At the age of 4 years her walk became unsteady and ataxic. Other signs of cerebellar involvement were soon observed. Head circumference was above two standard deviations (55 cm). Mild mental retardation was revealed by formal intelligence testing (IQ 60). MR examination of the brain showed confluent subcortical white matter lesions spread centripetally, and atrophy of the cerebellar vermis with involvement of dentate nuclei, without deep white matter abnormalities. Laboratory investigation revealed increased amounts and a very large peak of HGA in urine and plasma. Enantiomeric analysis confirmed the L-configuration (> 90%) establishing the diagnosis of L-2-HGA. The first epileptic seizure, partial with secondary generalization, occurred at age of 8 years. Favorable seizure control was achieved. A slow progression of neurological impairment was noted. Therapeutic trials with oral coenzyme Q10 and with oral riboflavin showed no biochemical and clinical effects. Recently, the diagnosis was proven by the presence of a mutation in the L-2-HGA gene. CONCLUSION: To our knowledge, this is the first report of L-2-HGA in Serbia. L-2-HGA must be considered in the differential diagnosis based on specific findings in cranial MRI.

Terminal remission is possible in some patients with juvenile myoclonic epilepsy without therapy.

INTRODUCTION: Juvenile myoclonic epilepsy is considered to be a chronic disease requiring lifelong antiepileptic treatment. The aim of this study was both to identify factors predicting the kind of seizure control and to investigate the outcome in patients after therapy withdrawal. MATERIAL AND METHODS: The study included 87 patients (49 female, 38 male), aged from 17.5 to 43.5 years, referred to our Department between 1987 and 2008, with the seizure onset at the age of 14.3±2.9, and followed up for 13.3±5.8 years on average (from 5 to 23 years). RESULTS: Sixty seven (77.0%) patients were fully controlled; whereas 13.8% had persistent seizures and 9.2% showed pseudoresistance. The combination of three seizure types and focal electroencephalogram features were independent factors of poor seizure control. Therapy was discontinued in 34 patients either by the treating physician (in 21 patients) or by the patients themselves (in 13 cases). In 18 subjects, all seizure types relapsed after 1.1 year on average (from 7 days to 4 years) and therapy was resumed in them. All patients but three (10/13), who stopped the treatment themselves, experienced recurrences. Seizure freedom off drugs was recorded in 10.3% patients. Nonintrusive myoclonic seizures recurred in 0.5-3 years as their only seizure type in four patients, but without reintroducing medication in three patients. CONCLUSION: Combination of seizure types and focal electroencephalogram features are significant factors of pharmacoresistancy. Continuous pharmacotherapy is required in majority of patients, although about 10% of them appear to have permanent remission without therapy in adolescence.

Epilepsy in children with subacute sclerosing panencephalitis.

INTRODUCTION: Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, fatal neurodegenerative disease of childhood and early adolescence caused by defective measles virus. The initial symptoms of SSPE usually involve regression in cognitive functioning and behavior or recurrent myoclonic jerks. Seizures revealing SSPE and epilepsy during the clinical course can occur. OBJECTIVE: The aim of the study was to analyze clinical and EEG characteristics of both initially occurred seizures and epilepsy which developed in the course of the disease. METHODS: Retrospective study was carried out on 19 children (14 boys, 5 girls) with SSPE diagnosed and treated at our Clinic from 1995 to 2010. Seizures revealed SSPE in our patients aged from 6.5 to 11.5 years (mean 8.6 years). RESULTS: SSPE onset ranged from 4.5 to 16.5 years (mean 10.05). Complete vaccination was performed in nine patients. Cognitive and behavioral decline was preceeded by 6-18 months in two children with intractable focal motor seizures with secondary generalization, one child with complex partial seizures and one with atypical absences. During the clinical course of the disease epilepsy developed in 10 (52.6%) cases, including four patients with seizures as the initial SSPE sign. It occurred mainly in the first year, while in three cases seizures appeared between 1 and 5 years of the disease evolution. Myoclonus was present independently from seizures. No significant inter-group differences were found relating to the type of SSPE progression and history of epilepsy. The only child with fulminant SSPE presented with initial seizures. Favorable seizure control was achieved in 60.0% patients. Intractable epilepsy developed in four patients. CONCLUSION: Atypical SSPE presentation can include mainly focal intractable seizures. Epilepsy developed during clinical course in 52.6% cases. No significant influence was found of the history of epilepsy on the type of SSPE progression.

Verbal memory impairment in children with focal epilepsy.

Findings of both material- and hemisphere-specific influence on memory performance in children with epilepsy are inconsistent. Verbal memory of 80 children with focal epilepsy, aged 7 to 16, was assessed and compared with verbal memory of 80 healthy schoolchildren. The Verbal Selective Reminding test was used to distinguish between patients with left-sided (N=38) and patients with right-sided (N=42) electroencephalographic focal abnormalities. In addition, groups with temporal (N=36) and extratemporal (N=44) focal epilepsy were compared. Effects of seizure-related variables were also assessed. Children with focal epilepsy scored significantly lower on tests when compared with the healthy group. Lateralization of the EEG focus was not found to significantly affect verbal memory performance. Only the CLTR component of the Verbal Selective Reminding test was susceptible to lateralization and localization effects. Differences between the group with left and the group with right temporal epilepsy (P<0.03) and between the group with temporal and the group with extratemporal epilepsy (P<0.01) reached statistical significance.
