Vitamin D deficiency and effect of treatment on seizure frequency and quality of life parameters in patients with drug-resistant epilepsy: A randomized clinical trial.

OBJECTIVE: This study was undertaken to assess the effect of treatment of vitamin D deficiency in drug-resistant epilepsy. METHODS: We conducted a multicenter, double-blind, placebo-controlled, randomized clinical trial, including patients aged ≥15 years with drug-resistant focal or generalized epilepsy. Patients with 25-hydroxyvitamin D (25[OH]D) < 30 ng/mL were randomized to an experimental group (EG) receiving vitamin D3 (cholecalciferol, 100 000 IU, five doses in 3 months) or a control group (CG) receiving matched placebo. During the open-label study, EG patients received 100 000 IU/month for 6 months, whereas CG patients received five doses in 3 months then 1/month for 3 months. Monitoring included seizure frequency (SF), 25(OH)D, calcium, albumin, creatinine assays, and standardized scales for fatigue, anxiety-depression, and quality of life (Modified Fatigue Impact Scale [M-FIS], Hospital Anxiety and Depression Scale, Quality of Life in Epilepsy [QOLIE-31]) at 3, 6, and 12 months. The primary efficacy outcome was the percentage of SF reduction compared to the reference period and CG at 3 months. Secondary outcomes were SF and bilateral tonic-clonic seizure (BTCS) reduction, scale score changes, and correlations with 25(OH)D during the follow-up. RESULTS: Eighty-eight patients were enrolled in the study (56 females, aged 17-74 years), with median baseline SF per 3 months = 16.5 and ≥2 antiseizure medications in 88.6%. In 75 patients (85%), 25(OH)D was <30 ng/mL; 40 of them were randomly assigned to EG and 34 to CG. After the 3-month blinded period, SF reduction did not significantly differ between groups. However, during the open-label period, SF significantly decreased (30% median SF reduction, 33% responder rate at 12 months). BTCSs were reduced by 52%. M-FIS and QOLIE-31 scores were significantly improved at the whole group level. SF reduction correlated with 25(OH)D > 30 ng/mL for >6 months. SIGNIFICANCE: Despite no proven effect after the 3-month blinded period, the open-label study suggests that long-term vitamin D3 supplementation with optimal 25(OH)D may reduce SF and BTCSs, with a positive effect on fatigue and quality of life. These findings need to be confirmed by further long-term studies. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03475225 (03-22-2018).

Report on Electroencephalographic Findings in Critically Ill Patients with COVID-19.

In March 2020, we treated a cohort of 26 critically ill hospitalized SARS-CoV-2-infected patients who underwent electroencephalography to assess unexplained altered mental status, loss of consciousness, or poor arousal and responsiveness. Of the 26 patients studied, 5 patients had electroencephalograms that showed periodic discharges consisting of high-amplitude frontal monomorphic delta waves with absence of epileptic activity. These findings may suggest central nervous system injury potentially related to COVID-19 in these patients. ANN NEUROL 2020;88:626-630.

Seizures and epilepsy in hypoglycaemia caused by inborn errors of metabolism.

AIM: The aim of the study was to characterize seizures and epilepsy related to hypoglycaemia. METHOD: We analyzed the files of 170 consecutive patients referred for hypoglycaemia (onset 1h to 4y) caused by inborn errors of metabolism (glycogen storage disease type I, fatty acid ß-oxidation disorders, and hyperinsulinism). RESULTS: Ninety patients (42 males and 48 females; 38 neonates and 52 infants/children) had brief hypoglycaemic seizures (68%) or status epilepticus (32%). Status epilepticus occurred earlier (mean 1.4d) than brief neonatal seizures (4.3d, p=0.02). Recurrent status epilepticus followed initial status epilepticus and was often triggered by fever. Epilepsy developed in 21 patients. In 18 patients, epilepsy followed hypoglycaemic status epilepticus and began with shorter delay when associated with grey matter lesions (1.9mo, standard error of the mean [SEM] 1mo) than with white matter damage (3.3y [SEM 1y], p=0.003). Three patients with hyperinsulinism developed idiopathic epilepsy following brief neonatal seizures. INTERPRETATION: Brief neonatal hyperinsulinaemic hypoglycaemic seizures have characteristics of idiopathic neonatal seizures. Neonatal status epilepticus should be prevented by the systematic measurement of glucose blood level. Recurrent seizures never consist of status epilepticus when following brief initial seizures. Epilepsy is symptomatic of brain damage with shorter delay in the case of grey rather than white matter lesions, except in a few idiopathic cases in which epilepsy and hyperinsulinism may share a common genetic background.

Vandetanib in locally advanced or metastatic differentiated thyroid cancer: a randomised, double-blind, phase 2 trial.

BACKGROUND: No effective standard treatment exists for patients with radioiodine-refractory, advanced differentiated thyroid carcinoma. We aimed to assess efficacy and safety of vandetanib, a tyrosine kinase inhibitor of RET, VEGFR and EGFR signalling, in this setting. METHODS: In this randomised, double-blind, phase 2 trial, we enrolled adults (aged ≥18 years) with locally advanced or metastatic differentiated thyroid carcinoma (papillary, follicular, or poorly differentiated) at 16 European medical centres. Eligible patients were sequentially randomised in a 1:1 ratio with a standard computerised scheme to receive either vandetanib 300 mg per day (vandetanib group) or matched placebo (placebo group), balanced by centre. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population based on investigator assessment. This study is registered with ClinicalTrials.gov, number NCT00537095. FINDINGS: Between Sept 28, 2007, and Oct 16, 2008, we randomly allocated 72 patients to the vandetanib group and 73 patients to the placebo group. By data cutoff (Dec 2, 2009), 113 (78%) patients had progressed (52 [72%] patients in the vandetanib group and 61 [84%] in the placebo group) and 40 (28%) had died (19 [26%] patients in the vandetanib group and 21 [29%] in the placebo group). Patients who received vandetanib had longer PFS than did those who received placebo (hazard ratio [HR] 0·63, 60% CI 0·54-0·74; one-sided p=0·008): median PFS was 11·1 months (95% CI 7·7-14·0) for patients in the vandetanib group and 5·9 months (4·0-8·9) for patients in the placebo group. The most common grade 3 or worse adverse events were QTc prolongation (ten [14%] of 73 patients in the vandetanib group vs none in the placebo group), diarrhoea (seven [10%] vs none), asthenia (five [7%] vs three [4%]), and fatigue (four [5%] vs none). Two patients in the vandetanib group and one in the placebo group died from treatment-related serious adverse events (haemorrhage from skin metastases and pneumonia in the vandetanib group and pneumonia in the placebo group). INTERPRETATION: Vandetanib is the first targeted drug to show evidence of efficacy in a randomised phase 2 trial in patients with locally advanced or metastatic differentiated thyroid carcinoma. Further investigation of tyrosine-kinase inhibitors in this setting is warranted. FUNDING: AstraZeneca.

Tusamitamab Ravtansine in Patients with Advanced Solid Tumors: Phase I Study of Safety, Pharmacokinetics, and Antitumor Activity Using Alternative Dosing Regimens.

Purpose: Tusamitamab ravtansine is an antibody-drug conjugate that targets carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) and delivers a cytotoxic maytansinoid payload. In a phase I dose-escalation study, the maximum tolerated dose (MTD) was 100 mg/m2 every 2 weeks (Q2W). Here we report results for two alternative schedules. Experimental Design: Adults ages ≥18 years (range, 34-73) with locally advanced/metastatic solid tumors (N = 43; colon/rectum, 29; stomach, 7; pancreas, 4; other, 3) expressing/likely to express CEACAM5 received intravenous tusamitamab ravtansine 120-170 mg/m2 [loading dose (LD)], then 100 mg/m2 Q2W (Q2W-LD, n = 28), or 120-190 mg/m2 fixed dose [every 3 weeks (Q3W), n = 15]. The primary endpoint was dose-limiting toxicities (DLTs) during cycles 1-2 (Q2W-LD) and cycle 1 (Q3W). Results: Reversible DLTs were observed in 2 of 9 patients (grade 2 keratopathy; grade 2 keratitis) with 170 mg/m2 in Q2W-LD and in 2 of 3 patients (grade 2 keratopathy; grade 3 transaminase elevation) with 190 mg/m2 in Q3W. Nineteen (67.9%) patients in Q2W-LD and 13 (86.7%) patients in Q3W experienced treatment-related adverse events (AE); 3 of 43 patients discontinued treatment because of AEs. The most common AEs were asthenia, gastrointestinal complaints, keratopathy, keratitis, and peripheral sensory neuropathy. In this small, heavily pretreated population, no confirmed responses were observed; however, stable disease occurred in 35.7% of patients in Q2W-LD and 40.0% of patients in Q3W. Conclusions: Tusamitamab ravtansine had a favorable safety profile with both alternative administration schedules; MTDs were 170 mg/m2 (LD) followed by 100 mg/m2 Q2W, and 170 mg/m2 Q3W as a fixed dose. (NCT02187848). Significance: The collective results of this phase I dose-escalation study will inform further studies of tusamitamab ravtansine in patients with solid tumors with CEACAM5 expression, including patients with non-small cell lung cancer.

[Epileptic seizures and syndromes in children. Classification]. / Crises et syndromes épileptiques chez l'enfant. Classification.

In front of any clinical paroxysmal event in childhood, the first step is to make a positive diagnostic of an epileptic seizure; for this it is necessary to eliminate non epileptic seizures which are different according to age. Then the type of seizures has to be precised, being focal or generalized. EEG will contribute to determine the epileptic syndrome according to interictal and/or ictal findings. The epilepsy syndrome is the main entity to go further in etiology and treatment. According to the type of epilepsy syndrome it will be possible to look for a structural or metabolic cause, or to perform a genetic study. The present classification of seizures and syndromes as proposed by the International League Against Epilepsy (ILAE) allows a common language in the world community as in clinical and therapeutic research.

Perspectives on gastroesophageal reflux disease in primary care: the REFLEX study of patient-physician agreement.

BACKGROUND: Physicians may be unaware of the severity and extent of gastroesophageal reflux disease (GERD) in their patients. The aim of this study was to evaluate patient-physician agreement concerning proton pump inhibitor (PPI) treatment. METHODS: 1818 French primary-care physicians and 5174 adult patients with GERD who were taking PPIs answered questions regarding symptoms and treatment satisfaction. Patient-physician agreement was scored using the Kappa (κ) method. RESULTS: There was moderate patient-physician agreement for PPI treatment satisfaction (κ = 0.60), PPI prescription adherence (κ = 0.57) and use of over-the-counter gastrointestinal medications (κ = 0.44-0.51). Patient satisfaction with PPI therapy and PPI treatment adherence rates were both ~90%. There was poor patient-physician agreement concerning PPI therapy expectations (κ = 0.22-0.33). Residual reflux symptoms occurred in 61% of patients. Physicians underestimated residual symptom severity compared with their patients (κ = 0.43-0.47), though there was good agreement regarding the presence (κ = 0.62-0.78) and frequency (κ = 0.61-0.66) of these symptoms and their effect on patients' daily life (κ = 0.64). CONCLUSIONS: Patient-physician agreement regarding PPI therapy for GERD was moderate or good for the presence of residual symptoms and moderate for treatment satisfaction, but poor for treatment expectations. PPI treatment resulted in high satisfaction rates, but residual symptoms were fairly common and their severity was underestimated by physicians.

GPR56-related bilateral frontoparietal polymicrogyria: further evidence for an overlap with the cobblestone complex.

GPR56 mutations cause an autosomal recessive polymicrogyria syndrome that has distinctive radiological features combining bilateral frontoparietal polymicrogyria, white matter abnormalities and cerebellar hypoplasia. Recent investigations of a GPR56 knockout mouse model suggest that bilateral bifrontoparietal polymicrogyria shares some features of the cobblestone brain malformation and demonstrate that loss of GPR56 leads to a dysregulation of the maintenance of the pial basement membrane integrity in the forebrain and the rostral cerebellum. In light of these findings and other data in the literature, this study aimed to refine the clinical features with the first description of a foetopathological case and to define the range of cobblestone-like features in GPR56 bilateral bifrontoparietal polymicrogyria in a sample of 14 patients. We identified homozygous GPR56 mutations in 14 patients from eight consanguineous families with typical bilateral bifrontoparietal polymicrogyria and in one foetal case, out of 30 patients with bifrontoparietal polymicrogyria referred for molecular screening. The foetal case, which was terminated at 35 weeks of gestation in view of suspicion of Walker Warburg syndrome, showed a cobblestone-like lissencephaly with a succession of normal, polymicrogyric and 'cobblestone-like' cortex with ectopic neuronal overmigration, agenesis of the cerebellar vermis and hypoplastic cerebellar hemispheres with additional neuronal overmigration in the pons and the cerebellar cortex. The 14 patients with GPR56 mutations (median 8.25 years, range 1.5-33 years) were phenotypically homogeneous with a distinctive clinical course characterized by pseudomyopathic behaviour at onset that subsequently evolved into severe mental and motor retardation. Generalized seizures (12/14) occurred later with onset ranging from 2.5 to 10 years with consistent electroencephalogram findings of predominantly anterior bursts of low amplitude α-like activity. Neuroimaging demonstrated a common phenotype with bilateral frontoparietally predominant polymicrogyria (13/13), cerebellar dysplasia with cysts mainly affecting the superior vermis (11/13) and patchy to diffuse myelination abnormalities (13/13). Additionally, the white matter abnormalities showed a peculiar evolution from severe hypomyelination at 4 months to patchy lesions later in childhood. Taken as a whole, these observations collectively demonstrate that GPR56 bilateral bifrontoparietal polymicrogyria combines all the features of a cobblestone-like lissencephaly and also suggest that GRP56-related defects produce a phenotypic continuum ranging from bilateral bifrontoparietal polymicrogyria to cobblestone-like lissencephaly.

Epileptic phenotypes in children with respiratory chain disorders.

PURPOSE: Epilepsy is a commonly reported but rarely described clinical hallmark of mitochondrial respiratory chain defects (RCDs) with encephalopathy. METHODS: From 1990-2006 we collected data about 56 children with RCD (single, n = 24 or multiple, n = 20 mitochondrial complex deficiencies; mtDNA mutation, n = 11; mtDNA depletion n = 10 of 21; and nuclear gene mutation n = 11). Epileptic features were reviewed retrospectively. RESULTS: First seizures were frequently (47 patients, 82.5%) preceded by failure to thrive, psychomotor delay, ataxia, or multisystemic dysfunction. Sixty percent of the patients had several seizure types. Six age-related epilepsy phenotypes could be identified: status epilepticus complicating neonatal multivisceral deficiency (2 patients), neonatal myoclonic encephalopathy (3 patients), infantile spasms (8 patients), refractory or recurrent status epilepticus (21 patients), epilepsia partialis continua (4 patients), and myoclonic epilepsy (18 patients). Except for infantile spasms, epilepsy was difficult to control in most patients (95%). Valproate was administered to 25 patients, one of whom developed acute liver failure 6 days later. Twenty-two patients (45%) died, half of them within 9 months from the onset of epilepsy. DISCUSSION: In RCD, epilepsy is not only difficult to control but its occurrence often indicates a severe turn in the course of the disease. For one-third of the patients, classical biochemical measures failed to reveal any abnormality and RCD could be detected in the liver only.

Sleep related epilepsy in focal cortical dysplasia type 2: Insights from sleep recordings in presurgical evaluation.

OBJECTIVE: To determine the relationship between seizure onset, sleep stage and focal cortical dysplasia type 2 (FCD2) location in sleep related epilepsy (SRE). METHODS: We reviewed scalp video-EEG data of 77 patients with SRE among 130 surgically treated patients with histologically confirmed FCD2. Seizure onset was classified as occurring during NREM, REM and after arousal. RESULTS: Sleep recordings were available for 65 patients (37 males, 7-49 years old). FCD2 was located in frontal lobe in 46 (71%) and in extra-frontal regions in 19, including the temporal lobe in 6. MRI was negative/doubtful in 35 cases. Interictal rhythmic/pseudorhythmic spike rate increased from 31% during waking to 65% during sleep. Seizure onset occurred from NREM in 46 cases (71%), mostly from stage 2, and after arousal in 14 (22%). Seizures occurring from NREM/REM sleep were significantly more frequent in frontal (89%) compared to extra-frontal location (42%), whilst arousal preceded seizure onset more often in extra-frontal (58%) compared to frontal location (7%). CONCLUSIONS: NREM seizure onset is the most common ictal pattern in SRE due to frontal FCD2 whereas preceding arousal points to extra-frontal regions. SIGNIFICANCE: Sleep recordings may help for FCD2 localisation and suggest topography dependent impact on sleep related epileptic networks.

The Effectiveness of Vagus Nerve Stimulation in Drug-Resistant Epilepsy Correlates with Vagus Nerve Stimulation-Induced Electroencephalography Desynchronization.

Introduction: VNS is an adjunctive neuromodulation therapy for patients with drug-refractory epilepsy. The antiseizure effect of VNS is thought to be related to a diffuse modulation of functional connectivity but remains to be confirmed. Aim: To investigate electroencephalographic (EEG) metrics of functional connectivity in patients with drug-refractory epilepsy treated by vagus nerve stimulation (VNS), between VNS-stimulated "ON" and nonstimulated "OFF" periods and between responder (R) and nonresponder (NR) patients. Methods: Scalp-EEG was performed for 35 patients treated by VNS, using 21 channels and 2 additional electrodes on the neck to detect the VNS stimulation. Patients were defined as VNS responders if a reduction of seizure frequency of ∼50% was documented. We analyzed the synchronization in EEG time series during "ON" and "OFF" periods of stimulation, using average phase lag index (PLI) in signal space and phase-locking value (PLV) between 10 sources. Based on graph theory, we computed brain network models and analyzed minimum spanning tree (MST) for responder and nonresponder patients. Results: Among 35 patients treated by VNS for a median time of 7 years (range 4 months to 22 years), 20 were R and 15 were NR. For responder patients, PLI during ON periods was significantly lower than that during OFF periods in delta (p = 0.009), theta (p = 0.02), and beta (p = 0.04) frequency bands. For nonresponder patients, there were no significant differences between ON and OFF periods. Moreover, variations of seizure frequency with VNS correlated with the PLI OFF/ON ratio in delta (p = 0.02), theta (p = 0.04), and beta (p = 0.03) frequency bands. Our results were confirmed using PLV in theta band (p < 0.05). No significant differences in MST were observed between R and NR patients. Conclusion: The correlation between VNS-induced interictal EEG time-series desynchronization and decrease in seizure frequency suggested that VNS therapeutic impact might be related to changes in interictal functional connectivity. Impact statement Electroencephalography (EEG) desynchronization has been proposed to be a mechanism for antiepileptic effect of vagus nerve stimulation (VNS). We measured interictal EEG time-series synchronization during stimulated (ON) and nonstimulated (OFF) periods in epileptic patients treated by VNS. Phase lag index differences between ON and OFF periods were measured in delta, theta, and beta bands only in responder patients. To our knowledge, our study is the first to statistically correlate interictal cortical desynchronization during ON periods with reduction in seizure frequency. Our result supports the hypothesis that the antiseizure effect of VNS is mediated by cortical desynchronization.

Mutational, functional, and expression studies of the TCF4 gene in Pitt-Hopkins syndrome.

Pitt-Hopkins syndrome is a severe congenital encephalopathy recently ascribed to de novo heterozygous TCF4 gene mutations. We report a series of 13 novel PHS cases with a TCF4 mutation and show that EEG, brain magnetic resonance imagain (MRI), and immunological investigations provide valuable additional clues to the diagnosis. We confirm a mutational hot spot in the basic domain of the E-protein. Functional studies illustrate that heterodimerisation of mutant TCF4 proteins with a tissue-specific transcription factor is less effective than that homodimerisation in a luciferase reporter assay. We also show that the TCF4 expression pattern in human embryonic development is widespread but not ubiquitous. In summary, we further delineate an underdiagnosed mental retardation syndrome, highlighting TCF4 function during development and facilitating diagnosis within the first year of life.

Myoclonic absence epilepsy with photosensitivity and a gain of function mutation in glutamate dehydrogenase.

Activating mutations in glutamate dehydrogenase (GDH), de novo or dominantly inherited, are responsible for the hyperinsulinism/hyperammonemia (HI/HA) syndrome. Epilepsy has been frequently reported in association with mutations in GDH, but the epilepsy phenotype has not been clearly determined. Here, we describe a family with a dominantly inherited mutation in GDH. The mother, brother and both sisters had myoclonic absence seizures, but only the mother and one sister had the complete HI/HA pattern. For the two sisters with myoclonic absences, epilepsy started during the second year of life while the brother, it started at 6 years. All 3 children showed the same EEG pattern characterized by photosensitive generalized and irregular spike-wave discharges and runs of multiple spikes. The mother's EEG recordings were normal without photosensitivity. Magnetic resonance imaging (MRI) and spectroscopy (MRS) were normal. A direct effect of the GDH mutation, perhaps in combination with recurrent hypoglycemia and chronic hyperammonemia could provide a pathophysiological explanation for the epilepsy observed in this syndrome and these are discussed.

Epilepsy associated with shaken baby syndrome.

OBJECT: The shaken baby syndrome (SBS) is an important cause of developmental delay in infants. Epileptic seizures are a common feature of this syndrome. The aim if this study is to analyse the impact of the early and late seizures disorder. MATERIALS AND METHODS: We have retrospectively reviewed the clinical and electrophysiological findings in a series of 404 children hospitalised with SBS. RESULTS: In the acute phase, clinical epileptic seizures of various semiologies were found in 73% of the infants. Only 11% of the children had a normal EEG on admission. A poor outcome was found in 88% of the children in case of persisting EEG anomalies despite anti-epileptic treatment with 48% mortality in these patients. The development of refractory epilepsy was also associated with a poor outcome in this series. In fact 96% of the children with seizure recurrence had behavioural problems. CONCLUSIONS: The early recognition and subsequent management of these seizures is vital to prevent further neurological injury. Delayed or recurrent epileptic seizures may occur with a different semiology to the seizures in the acute phase and are also associated with a poor prognosis.

Developmental aspects of normal EEG.

In pediatrics recording of EEG can range from premature infants aged just 25 weeks of gestation to young adults. Recording EEG in pediatrics ranges from 25 weeks of gestation premature in the incubator to young adults. Hence, recording conditions need to be adapted to very different situations, not only of age but also of environment, asepsis, and behavior.This requires that recording conditions be adapted to very different situations, not only of age but also of environment, asepsis and behavior. The two major determinants of EEG features are the level of vigilance and age. Standard examination includes spontaneous sleep until the age of 5 years, and hyperventilation and intermittent light stimulation in older children. Hyperventilation may modify the tracing in a physiological way until adolescence. One of the major characteristics of a child's EEG recording is its course over time that parallels rapid brain maturation. EEG changes are particularly rapid in early age and they involve both temporal and spatial organization. In premature babies modifications appear by two 2 weeks, in infancy by 1 month and in childhood by 1 year, before reaching the adult patterns at an age varying between 8 and 12 years of age. Apart from being aware of the normal EEG patterns according to thein children of different ages, it is important to recognize unusual patterns that are not linked to a pathological situation. Most important are the interpretation and the conclusion of the EEG tracing and any conclusions reached, for which and a precise knowledge besides clinical information is mandatory for this purpose is essential.

Sleep disturbances associated with gastro-oesophageal reflux disease: prevalence and impact of treatment in French primary care patients.

AIM: To evaluate the prevalence of sleep disturbances in French patients with gastro-oesophageal reflux disease and the impact of gastro-oesophageal reflux disease treatment on sleep. METHODS: A registry was compiled of all gastro-oesophageal reflux disease patients seen during a 2-week period by 1983 French primary care physicians. Data from the first two patients with nocturnal gastro-oesophageal reflux disease symptoms and gastro-oesophageal reflux disease-related sleep disturbances seen by each physician were derived from physician questionnaires and medical records. These patients completed a questionnaire during the initial consultation and after 1-month treatment. RESULTS: A total of 33,391 patients were included in the study: physician questionnaires were available for 3269 patients and patient questionnaires for 2876. Nocturnal gastro-oesophageal reflux disease symptoms were reported by 21,337 patients (63.9%) and regular (at least once weekly) gastro-oesophageal reflux disease-related sleep disturbances by 19,313 (61.7%). Multivariate analysis showed that nocturnal gastro-oesophageal reflux disease symptoms, use of hypnotic drugs, and age over 50 years were significant independent predictors of sleep disturbances. The proportion of patients reporting at least one nocturnal gastro-oesophageal reflux disease symptom during the previous week decreased following treatment, from 98.8% to 39.3% (P<0.001). CONCLUSIONS: Nocturnal gastro-oesophageal reflux disease symptoms are common in the French population and are associated with sleep disturbances. Effective treatment can significantly improve sleep duration and quality.

Upper gastrointestinal symptoms in patients treated with nonsteroidal anti-inflammatory drugs: prevalence and impact--the COMPLAINS study.

OBJECTIVES: To investigate the prevalence and type of upper gastrointestinal symptoms during nonsteroidal anti-inflammatory drug (NSAID) therapy, the impact of these symptoms on daily life and adherence to treatment and the concordance between physicians' and patients' assessments. METHODS: A sample of 1000 French rheumatologists was invited to participate in the study, of which 630 accepted. Participating physicians enrolled all patients above 18 years of age seen during a 1-week period who had been receiving daily NSAID treatment for at least 3 days (n = 8269). Data on gastrointestinal symptoms were collected using a standardized questionnaire. In the first two symptomatic patients seen by each physician, patient and physician questionnaires were used to investigate concordance between symptom evaluations. RESULTS: Two thousand seven hundred and ninety-nine patients (33.8%) reported upper gastrointestinal symptoms; of these, 1056 (12.8% of the total population) had acid reflux symptoms (heartburn and/or acid regurgitation). The most common symptoms were epigastric burning (17.3%) and epigastric discomfort or pain (14.4%). Symptoms were less common with coxibs than with nonselective NSAIDs (26.4 vs. 35.4%, P<10). There was moderate or good agreement between physicians' and patients' symptom assessments. Upper gastrointestinal symptoms resulted in NSAID dose reduction in 5.8% of patients, temporary withdrawal of treatment in 17.2% and permanent withdrawal in 10.8%. Half of the patients reported at least moderate impairment of daily activities because of their symptoms. CONCLUSION: Approximately, one-third of NSAID-treated patients complained of upper gastrointestinal symptoms, with coxibs being better tolerated than nonselective NSAIDs. These symptoms have a marked impact on the quality of life and adherence to therapy.

Spectrum of epilepsy in terminal 1p36 deletion syndrome.

PURPOSE: Previous reports have summarized the seizures types occurring in 1p36 deletion syndrome. To better define the spectrum of epilepsy, we studied 91 patients (median age 7.8 years) with confirmed 1p36 deletion. METHODS: Based on clinical charts, we retrospectively analyzed the evolution of both the EEG findings and seizures. RESULTS: Epilepsy occurred in 53 patients (58.2%), with onset at a median 2.75 months. First seizures were generalized tonic (8 cases), tonic and clonic (6) or myoclonic (12), simple partial (6), or complex partial (14). Thereafter, 20 patients (21.9%) developed infantile spasms with hypsarrhythmia, at a median age of 5 months. High doses of oral steroids were tried in nine cases, with a prompt remission of seizures in six. Among them, five were seizure-free at the time of evaluation. Conversely, two of three nonresponders to steroids developed severe and refractory epilepsy. At the time of evaluation, 32 patients were seizure-free, from a median age of 1.8 years. Nineteen patients (20.9%) had developed refractory epilepsy with polymorphic seizures, including generalized tonic and tonic-clonic seizures (13) combined with myoclonic seizures (11) and atypical absences (3), atonic seizures (2), or complex partial seizures (3). The EEG showed focal, multifocal or generalized spikes, polyspike, and waves, with poverty of the usual background rhythmic activities. CONCLUSIONS: Early epilepsy is a frequent finding in 1p36 deletion syndrome with infantile spasms as of the most common features that can contribute to a poor clinical outcome. Early diagnosis and management of infantile spasm in this condition is mandatory.

Clinical evaluation of ganaxolone in pediatric and adolescent patients with refractory epilepsy.

PURPOSE: A pilot study of the safety, tolerability, dose range and potential efficacy of ganaxolone for the treatment of refractory epilepsy in pediatric and adolescent subjects. METHODS: We report the results of a nonrandomized, nonblinded, open-label, dose-escalation trial of ganaxolone in pediatric subjects (5-15 years) suffering from refractory epilepsy. Subjects received an oral suspension of ganaxolone in a 1:1 complex with beta-cyclodextrin in a dose escalation (1 mg/kg, b.i.d. to 12 mg/kg t.i.d.) schedule over 16 days. This was followed by a maintenance period for 8 weeks. Subjects that showed significant response were eligible for a compassionate use extension period. RESULTS: Fifteen subjects enrolled, eight completed the trial and three continued in the open-label compassionate-use extension period. All subject exhibited refractory partial or generalized epilepsy. In an intent-to-treat analysis, four (25%) were considered substantial responders (>or=50% reduction in seizure frequency), two (13%) were considered moderate responders (between 25 and 50% reduction in seizure frequency) and the remainder were considered nonresponders (<24% reduction). Three subjects entered the extension phase, one remained essentially seizure-free for over 3.5 years of ganaxolone administration. Ganaxolone was tolerated well. A total of 17 adverse events were reported in 10 patients, all were considered mild to moderate in severity. Somnolence was the most frequently (nine) reported adverse event. CONCLUSIONS: This pilot study is consistent with other clinical studies indicating that ganaxolone has anticonvulsant activity in humans. The results of this study encourage the further study of ganaxolone as an antiepileptic therapy.
