Video game-induced reflex seizures via a smartphone

Reflex seizures are consistently evoked by a specific afferent stimulus or by patient activity. Patients experiencing reflex seizures when playing a game on a mobile phone are rarely reported. We describe a boy with reflex seizures after prolonged exposure to the game, Cut the rope, on his mobile phone. The videoEEG documented electroclinical events characterized by distal myoclonic jerks of the upper limbs, in combination with irregular, diffuse spike-and-wave and polyspike-and-wave discharges on EEG, followed by a tonic-clonic seizure. Playing video games on mobile phones may potentially induce reflex seizures, similar to other commonly used platforms such as docking stations connected to video screens

Vaccination and occurrence of seizures in SCN1A mutation-positive patients: A multicenter Italian study

Background The relation between epileptic seizures and vaccinations is sometimes debated. In the present work, the impact of vaccination on seizure onset and clinical outcome of SCN1A mutation-positive patients is addressed. Methods Seventy-two patients diagnosed with Dravet syndrome or generalized epilepsy with febrile seizure plus, carrying SCN1A mutations or not, were included. Details on vaccination type, temporal relationship between vaccination and seizure occurrence, seizure type at onset and during development, cognitive functioning, and vaccination completion was obtained by reviewing clinical records. Patients were divided into two groups based on the temporal window between vaccination and seizure onset (proximate group: 48 hours). Results Vaccination-related seizures occurred in 25% of patients with SCN1A mutation and 18% of patients without the mutation (no significant difference). The proximate group showed an earlier age at seizure onset and a higher frequency of status epilepticus during development than did the distant group. No other significant differences were found. Subsequent vaccinations did not significantly alter the evolution of the disease. Conclusions Results from this relatively small series provide evidence that vaccinations do not significantly affect clinical and cognitive evolution of Dravet syndrome and generalized epilepsy with febrile seizure plus patients even if they carry SCN1A mutations. © 2014 Elsevier Inc.

Randomized Double-Blind Crossover Study for Evaluating a Probiotic Mixture on Gastrointestinal and Behavioral Symptoms of Autistic Children

Autism spectrum disorders (ASDs) represent a diagnostic challenge with a still partially uncertain etiology, in which genetic and environmental factors have now been assessed. Among the hypotheses underlying the involvement of biological and environmental factors, the gut–brain axis is of particular interest in autism spectrum disorders. Several studies have highlighted the related incidence of particular gastrointestinal symptoms (GISs) in children suffering from ASDs. Probiotics have shown success in treating several gastrointestinal dysbiotic disorders; therefore, it is plausible to investigate whether they can alleviate behavioral symptoms as well. On these bases, a randomized double-blind crossover study with a placebo was conducted, evaluating the effects of a mixture of probiotics in a group of 61 subjects aged between 24 months and 16 years old with a diagnosis of ASD. Behavioral evaluation was performed through the administration of a questionnaire including a Parenting Stress Index (PSI) test and the Vineland Adaptive Behavior Scale (VABS). The Psycho-Educational Profile and the Autism Spectrum Rating Scale (ASRS) were also evaluated. Microbial composition analyses of fecal samples of the two groups was also performed. The study showed significant improvements in GISs, communication skills, maladaptive behaviors, and perceived parental stress level after the administration of probiotics. Microbiome alpha diversity was comparable between treatment arms and no significant differences were found, although beta diversity results were significantly different in the treatment group between T0 and T1 time points. Streptococcus thermophilus, Bifidobacterium longum, Limosilactobacillus fermentum, and Ligilactobacillus salivarius species were identified as some of the most discriminant taxa positively associated with T1 samples. This preliminary study corroborates the relationship between intestinal microbiota and ASD recently described in the literature

Impact and management of drooling in children with neurological disorders: an Italian Delphi consensus

Abstract Background The rate of chronic drooling in children older than 4 years is 0.5%, but it rises to 60% in those with neurological disorders. Physical and psychosocial consequences lead to a reduction in the quality of Life (QoL) of affected patients; however, the problem remains under-recognized and under-treated. We conducted an Italian consensus through a modified Delphi survey to discuss the current treatment paradigm of drooling in pediatric patients with neurological disorders. Methods After reviewing the literature, a board of 10 experts defined some statements to be administered to a multidisciplinary panel through an online encrypted platform. The answers to the questions were based on a 1–5 Likert scale (1 = strongly disagree; 5 = strongly agree). The scores were grouped into 1–2 (disagreement) and 4–5 (agreement), while 3 was discarded. The consensus was reached when the sum of the disagreement or agreement was ≥75%. Results Fifteen statements covered three main topics, namely clinical manifestations and QoL, quantification of drooling, and treatment strategies. All statements reached consensus (≥75% agreement). The 55 Italian experts agreed that drooling should be assessed in all children with complex needs, having a major impact on the QoL. Attention should be paid to investigating posterior hypersalivation, which is often neglected but may lead to important clinical consequences. Given that the severity of drooling fluctuates over time, its management should be guided by the patients’ current needs. Furthermore, the relative lack of validated and universal scales for drooling quantification limits the evaluation of the response to treatment. Finally, the shared therapeutic paradigm is progressive, with conservative treatments preceding the pharmacological ones and reserving surgery only for selected cases. Conclusion This study demonstrates the pivotal importance of a multidisciplinary approach to the management of drooling. National experts agree that progressive treatment can reduce the incidence of complications, improve the QoL of patients and caregivers, and save healthcare resources. Finally, this study highlights how the therapeutic strategy should be reconsidered over time according to the available drugs on the market, the progression of symptoms, and the patients’ needs

Seizures and EEG patterns in Pallister-Killian syndrome: 13 New Italian patients.

none15Background and objectives: PallistereKillian syndrome (PKS) is a rare genetic disorder caused by a tissue-limited mosaic supernumerary isochromosome 12p. Typical facial dysmorphisms, pigmentary abnormalities, and some major malformations are frequently present. Neurological manifestations include mental retardation, hypotonia, and seizures. Epilepsy incidence ranged from 39 to 59% in a previously reported series. No specific clinical and EEG phenotype has ever been reported to describe seizure features, electroclinical patterns, and response to therapy in PKS. Methods: This was a multicentre study conducted on 13 Italian children with PKS, as diagnosed by clinical phenotype and confirmed in cultured fibroblasts. All patients underwent several polygraphic video-EEG recordings and brain magnetic resonance imaging. Results and conclusions: All the patients presented with epilepsy and seizures that started at a mean age of 19 months. In six cases, epilepsy started with epileptic spasms (ES) combined with focal seizures in another case. In four cases, seizures were focal, and this was followed by ES in two patients. In only two cases, epilepsy started with myoclonic seizures, and spasms were never observed. The study provides further evidence that epilepsy is a part of the phenotype of PKS, although a specific clinical and EEG pattern could not benoneL.Giordano; M.Viri; R.Borgatti; M.Lodi; P.Accorsi; F.Faravelli; MC.Ferretti; R.Grasso; L.Memo; S.Prola; D.Pruna; M.Santucci; S.Savasta; A.Verrotti; A.RomeoL.Giordano; M.Viri; R.Borgatti; M.Lodi; P.Accorsi; F.Faravelli; MC.Ferretti; R.Grasso; L.Memo; S.Prola; D.Pruna; M.Santucci; S.Savasta; A.Verrotti; A.Rome

The Usefulness of a Targeted Next Generation Sequencing Gene Panel in Providing Molecular Diagnosis to Patients With a Broad Spectrum of Neurodevelopmental Disorders

Background: Neurodevelopmental disorders comprise a clinically and genetically heterogeneous group of conditions that affect 2%-5% of children and represents a public health challenge due to complexity of the etiology. Only few patients with unexplained syndromic and non-syndromic NDDs receive a diagnosis through first-tier genetic tests as array-CGH and the search for FMR1 CGG expansion. The aim of this study was to evaluate the clinical performance of a targeted next-generation sequencing (NGS) gene panel as a second-tier test in a group of undiagnosed patients with NDDs. Method: A 221-gene next-generation sequencing custom panel was designed and used to analyze a cohort of 338 patients with a broad spectrum of NDDs (202 males and 136 females) including Intellectual Disability (ID), Autism Spectrum Disorders (ASD), Epilepsy, language and motor disorders. Results: A molecular diagnosis was established in 71 patients (21%) and a de novo origin was present in 38 (64.4%) of the available trios. The diagnostic yield was significantly higher in females than in males (29.4% vs. 15.3%; p = 0.0019) in particular in ASD (36.8% vs. 7.6%; p = 0.0026) and Epilepsy (38.9% vs. 14.4% p = 0.001). The most involved genes were SLC2A1, SCN1A, ANKRD11, ATP1A2, CACNA1A, FOXP1, and GNAS altered in more than two patients and accounting for the 19.7% of the diagnosis. Conclusion: Our findings showed that this NGS panel represents a powerful and affordable clinical tool, significantly increasing the diagnostic yield in patients with different form of NDDs in a cost- and time-effective manner without the need of large investments in data storage and bioinformatic analysis
