RESUMEN
The International League against Epilepsy (ILAE) proposed a diagnostic scheme for psychogenic non-epileptic seizure (PNES). The debate on ethical aspects of the diagnostic procedures is ongoing, the treatment is not standardized and management might differ according to age group. The objective was to reach an expert and stakeholder consensus on PNES management. A board comprising adult and child neurologists, neuropsychologists, psychiatrists, pharmacologists, experts in forensic medicine and bioethics as well as patients' representatives was formed. The board chose five main topics regarding PNES: diagnosis; ethical issues; psychiatric comorbidities; psychological treatment; and pharmacological treatment. After a systematic review of the literature, the board met in a consensus conference in Catanzaro (Italy). Further consultations using a model of Delphi panel were held. The global level of evidence for all topics was low. Even though most questions were formulated separately for children/adolescents and adults, no major age-related differences emerged. The board established that the approach to PNES diagnosis should comply with ILAE recommendations. Seizure induction was considered ethical, preferring the least invasive techniques. The board recommended looking carefully for mood disturbances, personality disorders and psychic trauma in persons with PNES and considering cognitive-behavioural therapy as a first-line psychological approach and pharmacological treatment to manage comorbid conditions, namely anxiety and depression. Psychogenic non-epileptic seizure management should be multidisciplinary. High-quality long-term studies are needed to standardize PNES management.

OBJECTIVE: A previous European cost-utility study reported that use of buccal midazolam in the community setting for the treatment of prolonged seizures (ie, seizures lasting ≥5 minutes) in children was associated with an overall 12 507 399 reduction in annual costs charged to the Italian national health service compared with rectal diazepam. We re-evaluated these findings by applying a more conservative approach. METHODS: The Italian Delphi panel reconvened to apply a more conservative assessment of available reports. A decision-tree model was used, allowing for different treatment pathways depending on whether or not a caregiver administers treatment, an ambulance is required for transport of the child to hospital, and an inpatient stay is required. Direct medical costs were derived from Italian healthcare system data. Estimates of the annual number of prolonged tonic-clonic seizures expected in the country were based on studies which assessed seizure duration using video-EEG recordings and medical records. RESULTS: Although drug acquisition costs were greater for buccal midazolam than for rectal diazepam, the acquisition cost difference was outweighed by larger cost savings resulting mostly from a reduction in hospital admissions. Assuming that 1.2% of tonic and/or clonic seizures occurring in children and adolescents over a 12-month period are prolonged, the annual nationwide reduction in costs from preferring buccal midazolam to rectal diazepam was estimated at 3 577 587.9. CONCLUSIONS: In this more conservative revised analysis, the high cost of buccal midazolam is still counteracted by greater cost savings compared with rectal diazepam, but cost reduction was less than previously estimated.

Wireless pH monitoring of the esophagus has been widely used to detect GERD for more than a decade. It is generally well tolerated and accepted by patients, but it is still unclear whether prolonging a recording beyond the usual 48 hours can improve the test's diagnostic value. The aim of this study is to examine the diagnostic yield of 96-hour pH monitoring vis-à-vis 24- and 48-hour tests, and to ascertain whether any gain in diagnostic terms was of genuine clinical utility. Patients with suspected GERD underwent 4-day PPI-off wireless pH monitoring of the distal esophagus. The capsule was inserted under endoscopic control, 6 cm above the squamocolumnar junction. Average acid exposure time was calculated after 24, 48, and 96 hours of recording. Ninety-nine patients completed the 96 hour test, and formed the study sample. The wireless test method was used in 42 patients (42.4%) unable to tolerate the traditional pH-monitoring catheter, and in 57 (57.6%) with a previous negative pH study despite symptoms suggestive of GERD. On complete analysis, 47 patients (47.5%) had a pathological test result: 19 patients within the first 24 hours (19.2%, 24 hour group); another 16 after 48 hours (+16.2%, 48 hour group), and a further 12 (+12.1%, 96 hour group) only after 96 hours of monitoring. All 47 patients with an abnormal acid exposure were offered and accepted surgery (10 patients) or medical therapy (37 patients). Clinical follow-up was obtained in all patients with a positive Bravo test result after a median 67 months (IQR: 38-98) using a validated symptom questionnaire. A good outcome after fundoplication or medical therapy was achieved in 73.7% of patients in the 24 hour group, in 62.5% of those in the 48 hour group, and in only 25% of those in the 96 hour group, P = 0.02. Long-term wireless pH monitoring enables an increase in the diagnostic yield over traditional 24- and 48-hour pH studies, but prolonging the test may constitute an unwanted bias and prompt the recruitment of more complex patients, in whom the outcome of surgical or medical therapy may prove less than satisfactory. These findings should be taken into account when establishing the guidelines for assessing GERD with such long-term pH monitoring methods.

BACKGROUND AND PURPOSE: Our aim was to describe the clinical and electrical features and the long-term evolution of childhood occipital epilepsy of Gastaut (COE-G) in a cohort of patients and to compare long-term prognosis between patients with and without other epileptic syndromes. METHODS: This was a retrospective analysis of the long-term outcome of epilepsy in 129 patients with COE-G who were referred to 23 Italian epilepsy centres and one in Austria between 1991 and 2004. Patients were evaluated clinically and with electroencephalograms for 10.1-23.0 years. The following clinical characteristics were evaluated: gender, patient age at seizure onset, history of febrile seizures and migraine, family history of epilepsy, duration and seizure manifestations, circadian distribution and frequency of seizures, history of medications including the number of drugs, therapeutic response and final outcome. RESULTS: Visual hallucinations were the first symptom in 62% and the only manifestation in 38.8% of patients. Patients were subdivided into two groups: group A with isolated COE-G; group B with other epileptic syndromes associated with COE-G. The most significant (P < 0.05) difference concerned antiepileptic therapy: in group A, 45 children responded to monotherapy; in group B only 15 children responded to monotherapy. At the end of follow-up, the percentage of seizure-free patients was significantly higher in group A than in group B. CONCLUSIONS: Childhood occipital epilepsy of Gastaut has an overall favourable prognosis and a good response to antiepileptic therapy with resolution of seizures and of electroencephalogram abnormalities. The association of typical COE-G symptoms with other types of seizure could be related to a poor epilepsy outcome.

BACKGROUND AND PURPOSES: To determine the prevalence of SLC2A1 mutations in children with early-onset absence epilepsy (EOAE) and to investigate whether there were differences in demographic and electroclinical data between patients who became seizure-free with anti-epileptic drug (AED) monotherapy (group I) and those who needed add-on treatment of a second AED (group II). METHODS: We reviewed children with EOAE attending different Italian epilepsy centers. All participants had onset of absence seizures within the first 3 years of life but otherwise conformed to a strict definition of childhood absence epilepsy. Mutation analysis of SLC2A1 was performed in each patient. RESULTS: Eighty-four children (57 in group I, 27 in group II) fulfilled the inclusion criteria. No mutation in SLC2A1 was found. There were no statistical differences between the two groups with regard to F/M ratio, age at onset of EOAE, early history of febrile seizures, first-degree family history for genetic generalized epilepsy, duration of AED therapy at 3 years after enrollment, use of AEDs at 3 years, failed withdrawals at 3 years, terminal remission of EOAE at 3 years, and 6-month follow-up EEG data. Mean duration of seizures/active epilepsy was significantly shorter in group I than in group II (P = 0.008). CONCLUSIONS: We demonstrate that in a large series of children with rigorous diagnosis of EOAE, no mutations in SLC2A1 gene are detected. Except for duration of seizures/active epilepsy, no significant differences in demographic and electroclinical aspects are observed between children with EOAE who responded well to AED monotherapy and those who became seizure-free with add-on treatment of a second AED.

The aim of this multicentric, retrospective, and uncontrolled study was to evaluate the efficacy and safety of levetiracetam (LEV) in 81 children younger than 4 years with refractory epilepsy. At an average follow-up period of 9 months, LEV administration was found to be effective in 30% of patients (responders showing more than a 50% decrease in seizure frequency) of whom 10 (12%) became seizure free. This efficacy was observed for focal (46%) as well as for generalized seizures (42%). In addition, in a group of 48 patients, we compared the initial efficacy (evaluated at an average of 3 months of follow-up) and the retention at a mean of 12 months of LEV, with regard to loss of efficacy (defined as the return to the baseline seizure frequency). Twenty-two patients (46%) were initial responders. After a minimum of 12 months of follow-up, 9 of 48 patients (19%) maintained the improvement, 4 (8%) of whom remained seizure free. A loss of efficacy was observed in 13 of the initial responders (59%). Maintained LEV efficacy was noted in patients with focal epilepsy and West syndrome. LEV was well tolerated. Adverse events were seen in 18 (34%) patients. The main side effects were drowsiness and nervousness. Adverse events were either tolerable or resolved in time with dosage reduction or discontinuation of the drug. We conclude that LEV is safe and effective for a wide range of epileptic seizures and epilepsy syndromes and, therefore, represents a valid therapeutic option in infants and young children affected by epilepsy.

PURPOSE: To better delineate the electroclinical features of infants who presented with focal seizures and typical midline sleep EEG abnormalities with a benign outcome. We discuss the significance of the typical EEG marker in non-epileptic patients. METHODS: Patients were selected from a group of epileptic subjects with seizure onset less than 3 years we observed from 1st November 1990 and 31st December 2003. Inclusion criteria were the presence of typical sleep EEG marker and focal seizures with benign outcome. Cases with less than 18 month follow-up period were excluded from this study. RESULTS: There were 19 patients (12 males, 7 females). Pre-, peri- and post-natal personal history was negative in all patients. Psychomotor development was normal, both before and after seizure onset. Neuroradiological investigations gave normal results. Seizure manifestations were typical, characterized by cyanosis, staring and rare lateralizing signs, of short duration. Age at onset was comprised between 4 and 30 months. The typical EEG marker, a spike followed by a bell-shaped slow-wave, localized in the midline regions, was present in all subjects only during sleep. All had a favorable outcome and the overwhelming majority of the patients were not treated. CONCLUSIONS: Our patients have an homogeneous electroclinical picture to constitute a new epileptic syndrome not included in the ILAE classification. We propose to call it 'benign focal epilepsy in infancy with midline spikes and waves during sleep' (BIMSE).

PURPOSE: To evaluate the efficacy and tolerability of Perampanel (PER) in children and adolescents with refractory epilepsies in daily clinical practice conditions. PATIENTS AND METHODS: This Italian multicenter retrospective observational study was performed in 16 paediatric epilepsy centres. Inclusion criteria were: (i) ≤18 years of age, (ii) history of refractory epilepsy, (iii) a follow-up ≥5 months of PER add-on therapy. Exclusion criteria were: (i) a diagnosis of primary idiopathic generalized epilepsy, (ii) variation of concomitant AEDs during the previous 4 weeks. Response was defined as a ≥50% reduction in monthly seizure frequency compared with the baseline. RESULTS: 62 patients suffering from various refractory epilepsies were included in this study: 53% were males, the mean age was 14.2 years (range 6-18 years), 8 patients aged <12 years. Mean age at epilepsy onset was 3.4 years and the mean duration of epilepsy was 10.8 years (range 1-16), which ranged from 2 seizures per-month up to several seizures per-day (mean number=96.5). Symptomatic focal epilepsy was reported in 62.9% of cases. Mean number of AEDs used in the past was 7.1; mean number of concomitant AEDs was 2.48, with carbamazepine used in 43.5% of patients. Mean PER daily dose was 7.1mg (2-12mg). After an average of 6.6 months of follow-up (5-13 months), the retention rate was 77.4% (48/62). The response rate was 50%; 16% of patients achieved ≥75% seizure frequency reduction and 5% became completely seizure free. Seizure aggravation was observed in 9.7% of patients. Adverse events were reported in 19 patients (30.6%) and led to PER discontinuation in 4 patients (6.5%). The most common adverse events were behaviour disturbance (irritability and aggressiveness), dizziness, sedation and fatigue. CONCLUSION: PER was found to be a safe and effective treatment when used as adjunctive therapy in paediatric patients with uncontrolled epilepsy.

Monotherapy with lamotrigine or carbamazepine was evaluated in a multicentre open trial of patients aged 2 years and above with newly diagnosed partial epilepsy. A total of 417 patients were randomised to treatment with lamotrigine, while 201 patients received carbamazepine. Following a dose escalation period of 6 weeks, maintenance therapy (Weeks 7-24) was adjusted according to response. Efficacy was similar with both treatments (65% with lamotrigine, 73% with carbamazepine, P=0.085). Efficacy was assessed by the proportion of patients seizure free during the last 16 weeks of treatment; all subjects who remained in the study for at least 18 weeks after the week 4 visit were included in the analysis. More patients receiving lamotrigine completed the study (81%), compared with those receiving carbamazepine (77%). This difference was primarily due to discontinuation as a result of adverse events, reported by 34 (8%) of those treated with lamotrigine but 26 (13%) of those treated with carbamazepine. The proportion of patients who experienced adverse events in the lamotrigine group was lower (218 patients, 52%) compared with the carbamazepine group (120 patients, 60%). The proportion of patients with adverse events considered to be drug related was lower in the lamotrigine group (132 patients, 32%) compared with the carbamazepine group (83 patients, 41%). Somnolence was the only adverse event reported at an incidence of greater than 5% and where there was a difference of 5% or more between treatment groups (4% lamotrigine, 11% carbamazepine patients). The small subsets of elderly patients (aged 65 years or over) and paediatric patients (aged 2-12 years) also showed better tolerability to lamotrigine than to carbamazepine. In conclusion, monotherapy with lamotrigine is as effective as carbamazepine in patients with newly diagnosed partial epilepsy. Patients were able to tolerate lamotrigine better than carbamazepine, so more patients receiving lamotrigine were able to remain on therapy.

This was a prospective open comparative pilot study to assess the efficacy and tolerability of first-line vigabatrin monotherapy in childhood partial epilepsies. Two groups of patients were recruited over the same period. The vigabatrin monotherapy group comprised 40 patients (18 male, 22 female; mean age at last visit 7.5 years); the comparative carbamazepine monotherapy group comprised 40 consecutive clinic patients (22 male, 18 female; mean age at last visit 7.8 years). Seizures disappeared in 82% of vigabatrin patients and in all carbamazepine patients with idiopathic partial epilepsy, and in 50% of vigabatrin patients and 55% of carbamazepine patients with symptomatic partial epilepsy. Interictal EEG abnormalities decreased in vigabatrin patients more than in carbamazepine patients (P < 0.05). Tolerability was good in vigabatrin patients, but four out of 37 showed mild irritability by the end of the trial. Persistent sedation was observed in eight of the 40 patients receiving carbamazepine. No patient had drug therapy discontinued because of side-effects. During vigabatrin long-term monotherapy, efficacy and good clinical tolerability were maintained. These results suggest that vigabatrin may be an alternative first-line treatment for childhood partial epilepsies. Further blinded comparative randomized trials are needed.

In infancy, partial epilepsies have been considered with suspicion for their probable association with brain lesions. Japanese authors first described partial epilepsies in infancy with a favorable outcome and called them benign partial epilepsy in infancy with complex partial seizures. Similar, but familial, cases with onset during the first year of life were described some years later and called benign infantile familial convulsions. Similar familial cases with subsequent choreoathetosis were described in 1997 and called infantile convulsions and choreoathetosis. Benign infantile convulsions have also been described in association with mild gastroenteritis. Interictal electroencephalography (EEG) was always normal in all of these forms. More recently, a new epileptic syndrome characterized by partial seizures with onset between ages 13 and 30 months, a benign outcome, and characteristic EEG abnormalities in the vertex regions during sleep has been described. There is also an early-onset benign childhood occipital seizure susceptibility syndrome that can start in infancy.

Seven subjects with Chiari I malformations and seizures (four males, three females; age range 11 years, 7 months to 36 years; mean, 22.28 +/- 7.58 years; median, 21) were identified in four different centers from among a group of 10 patients. Our aim was to analyze clinical and electroencephalographic characteristics of seizures in this etiologically homogeneous group of patients. Most of the seizures were of the complex partial type, and paroxysmal abnormalities were mainly localized over the frontal and temporal regions. The course of the epilepsy was rather benign, with complete control of seizures in four patients and an important reduction in frequency in the remaining three subjects. Other cortical alterations are not usually associated with the typical abnormalities of the posterior fossa in Chiari I malformation; thus, it is possible to hypothesize that cerebral microdysgenesis or, alternatively, a cerebellar dysfunction could underlie epileptogenesis in these patients.

The aim of our study was to evaluate the effectiveness of ethosuximide in the treatment of epileptic negative myoclonus, a motor disorder that can occur in childhood partial epilepsy. We introduced ethosuximide in nine patients with partial epilepsy of varying etiology (idiopathic, cryptogenic, symptomatic) who presented with epileptic negative myoclonus. The drug was added to the patients' preexisting antiepileptic drugs, which were maintained unchanged for the following 6 months. Epileptic negative myoclonus disappeared in all patients 15 to 30 days after ethosuximide was started. Plasma ethosuximide levels ranged from 55 to 89 micrograms/mL. The clinical response was not influenced by the patients' preexisting treatment or by the etiology of the epilepsy. No side effects were observed, and none of the patients presented a recurrence of epileptic negative myoclonus during follow-up. Furthermore, in five patients we observed the disappearance of partial seizures; in the remaining patients seizures were reduced by more than 75%. Electroencephalograms showed a decrement or disappearance of focal paroxysmal abnormalities. Our results suggest that ethosuximide is effective in the treatment of epileptic negative myoclonus and that it should be considered as a first-choice drug in the treatment of this motor disorder.

Seckel's syndrome is a rare form of primordial dwarfism, characterized by peculiar facial appearance. In the past, this condition was overdiagnosed, and most attention was given to the facial and skeletal features to define more precise diagnostic criteria. The presence of mental retardation and neurologic signs is one of the peculiar features of this syndrome, but only recently were rare cases of malformation of cortical development described, as documented by magnetic resonance imaging (MRI). Here, we present three new cases of Seckel's syndrome showing different malformations of cortical development (one gyral hypoplasia, one macrogyria and partial corpus callosum agenesis, and one bilateral opercular macrogyria). We hypothesize that the different types of clinical expression of our patients could be explained by different malformation of cortical development types. We think that MRI studies could be performed in malformative syndromes because of the possible correlations between type and extent of the lesion and the clinical picture of any individual case.

International epilepsy classification includes different epileptic syndromes with favourable outcomes in paediatric age, both partial and generalised. This is true in childhood while no partial benign forms are accepted in infancy. In 1987, Watanabe first described a new entity and he defined it as 'benign complex partial epilepsies in infancy'. In 1992, Vigevano referred similar but familial cases whose seizures had secondary generalisation. Both these forms had no interictal EEG abnormalities neither awake nor during sleep. This article presents a survey of 12 cases of partial epilepsy with favourable outcome differing from Watanabe and Vigevano's cases, both for the presence of interictal EEG abnormalities only during sleep and for seizure picture. All our patients are neurologically and neuroradiologically normal. Psychomotor development is unremarkable. Age onset range is 13-30 months. All cases present characteristic spikes and waves during slow-sleep in vertex cerebral areas. Awake EEG is always normal, at follow-up too. Our cases have such homogeneous electroclinical features as to hypothesise a new partial idiopathic epileptic syndrome with favourable outcome in infancy and early childhood. We propose to define it as 'benign partial epilepsy in infancy and early childhood with vertex spikes and waves' (BVSE).

International epilepsy classification includes different epileptic syndromes with favourable outcomes in pediatric age. In addition to these, other forms probably exist and in various papers in international literature they are proposed as new entities. This article presents a survey of benign complex partial epilepsy in infancy, a new epileptic syndrome first proposed by Watanabe, in 1987. Our work represents the only description of non-Japanese cases although similar but familial cases had been referred by Vigevano in 1992. We present data for 12 children (aged up to 9 years) followed over 2 years who had all the typical clinical features characterizing Watanabe's cases. For all of them we obtained EEG seizure recordings demonstrating the partial nature of their fits, arising from occipital or temporal regions. Interictal EEG were completely normal, both in waking and sleep. Evolution demonstrated benign outcome and all the children are seizure-free (eight of them have already stopped all medication) and all have normal psychomotor development.

We investigated the electroclinical features of 12 patients with childhood absence epilepsy (CAE), presenting with typical absence seizures associated with myoclonic manifestations of the face or neck. All patients underwent repeated and prolonged split-screen video-polygraphic EEG recordings. The polygraphic recordings and clinical correlations of the absence seizures were analysed. All patients presented with multi-quotidian, typical absence seizures. During the absences, the patients could show mild, rhythmic, myoclonic jerks involving facial areas (eyebrows, nostrils, perioral region, chin) or neck muscles (sternocleidomastoideus), with the same frequency as the spike-wave complexes. Polygraphic tracings demonstrated that the myoclonias were correlated to the spike component. Clinically, all patients showed a benign course, with complete seizure control under antiepileptic treatment. In the follow-up, 7 patients withdrew from treatment without relapse. We conclude that all our patients showed an electroclinical picture consistent with CAE. The occurrence of myoclonic manifestations of the face or neck associated with the absences did not influence the benign course of their disease. The electroclinical features observed in our group of patients differentiates our cases both from epilepsy with myoclonic absences and from absences with perioral myoclonia (with Video).
