- Abstract
Volatile Binding Media (VBM) are waxy solids that can be used for temporary consolidation of heritage artifacts and architectural surfaces thanks to their spontaneous sublimation at room temperature. They are used to temporary shelter, consolidate or protect materials during high-risk operation, such as excavation, transportation, water-based treatments, etc. Although they are employed since the 1990s, research focused almost entirely on one of them, cyclododecane (CDD), which is by far the most used in onsite applications. However, CDD exhibits some drawbacks, including a fixed sublimation speed that hardly fits into all the possible applications and climates, hence the development of new VBM is strongly needed. In recent years, a certain attention was addressed to menthol as a possible alternative, but the research on other possible substitutes is still lacking. In this paper, a range of different VBM for temporary consolidation of cultural heritage materials was prepared and investigated, including five pure compounds (CDD, cyclododecanol, cyclododecanone, menthol and camphene) and fifteen mixes. These new materials are expected to provide tunable properties in terms of melting temperatures and sublimation rates, allowing their use in a variety of climatic contexts and applications, and to exhibit better properties for onsite applications compared to CDD, such as lower flash point, lower hazard for conservators' health and/or higher availability., (© 2024.

- Abstract
The fast diffusion of the SARS-CoV-2 pandemic have called for an equally rapid evolution of the therapeutic options.The Human recombinant monoclonal antibodies (mAbs) have recently been approved by the Food and Drug Administration (FDA) and by the Italian Medicines Agency (AIFA) in subjects aged ≥12 with SARS-CoV-2 infection and specific risk factors.Currently the indications are specific for the use of two different mAbs combination: Bamlanivimab+Etesevimab (produced by Eli Lilly) and Casirivimab+Imdevimab (produced by Regeneron).These drugs have shown favorable effects in adult patients in the initial phase of infection, whereas to date few data are available on their use in children.AIFA criteria derived from the existing literature which reports an increased risk of severe COVID-19 in children with comorbidities. However, the studies analyzing the determinants for progression to severe disease are mainly monocentric, with limited numbers and reporting mostly generic risk categories.Thus, the Italian Society of Pediatrics invited its affiliated Scientific Societies to produce a Consensus document based on the revision of the criteria proposed by AIFA in light of the most recent literature and experts' agreement.This Consensus tries to detail which patients actually have the risk to develop severe disease, analyzing the most common comorbidities in children, in order to detail the indications for mAbs administration and to guide the clinicians in identifying eligible patients., (© 2022.

- Abstract
Purpose: Pervasive refusal syndrome (PRS) is a rare psychiatric disease that affects children. It was first described by Lask in 1991 (Arch Dis Child 66:866-869, 1991). Recently, Otasowie and Collaborators reported a systematic review about PRS. Despite this, PRS has not yet been classified in DSM-5 and ICD-11 and the lack of evidence-based treatment makes this syndrome a real challenge for clinicians. The aim of this paper is to present our experience through the description of a case report and its treatment., Methods and Results: The case reported is a girl aged 11 years that fits the clinical picture described in the literature of PRS. In previous reports, behavioural treatment was not used or appreciated; our case adds new knowledge regarding the PRS diagnosis and the successful behavioural treatment during hospitalization, which we describe in all its phases., Conclusion: PRS is a rare, life-threatening syndrome; it would be extremely important to have an official and evidence-based treatment guide., Level of Evidence: Level V, case report., (© 2020.

- Abstract
The relationship between sensory profile and repetitive behaviours in autism spectrum disorder (ASD) has long been known. However, there is no consensus on the type of relationship that exists between them. This monocentric retrospective-prospective observational study aimed (a) to detect a clinical correlation between the severity of repetitive behaviours and the alterations of sensory profile in a sample of 50 children diagnosed with ASD; (b) to evaluate how different patterns of stereotypies and sensory alterations correlate with each other and with the main clinical-instrumental variables in the same sample. We enrolled 29 children in the retrospective phase of the study and 21 in the prospective phase. The Repetitive Behaviour Scale-Revised (RBS-R) and the Short Sensory Profile (SSP) were administered to the caregivers, and clinical-instrumental data were collected. SSP and RBS-R total scores directly correlated with a high significance rate. Among the subscales, the strongest correlations involved "Visual/Auditory Sensitivity", related to "Stereotyped Behaviour" and "Sameness Behaviour". "Under-Responsive/Seeks Sensation" related to "Stereotyped Behaviour". Sex and intellectual disability significantly influenced both the stereotypies and the sensory alterations of the examined population. In conclusion, this study provides new insights into the relationship between sensory alterations and repetitive behaviours in ASD children by using direct medical observation and parent observation.

- Abstract
Stereotypies are among the core symptoms of Autism spectrum disorder (ASD) and can cause significant clinical impairment. At present, phonic stereotypies in ASD have been scarcely explored. This study investigates the frequency, variability, and typologies of phonic and motor stereotypies in children with ASD and their association with clinical neurological variables. We examined 35 patients by recording standardized video sessions and administering the Autism Diagnostic Observation Schedule-Second Edition (ADOS-2). Phonic stereotypies were present in 83.0% of the patients. The most prevalent subtypes were noncommunicative vocalizations (60.0%), single syllables (37.1%), and echolalic stereotypies (22.9%). Noncommunicative vocalizations were more frequent in nonverbal patients (OR = 4.629, p = 0.008), while echolalic stereotypies were more represented in verbal patients (OR = 0.279, p = 0.028). Patients with intellectual disability (ID) showed a higher number (F(1,26) = 9.406, p = 0.005) and variability (F(1,25) = 7.174, p = 0.013) of motor stereotypies, with a higher number (F(1,26) = 13.268, p = 0.005) and variability (F(1,26) = 9.490, p = 0.005) of stereotypies involving the head/trunk/shoulders category. Patients with guttural stereotypies showed a higher variability of total motor stereotypies (OR = 1.487, p = 0.032) and self-directed motor stereotypies (OR = 4.389, p = 0.042). These results, combined with a standardized video-analysis, document the frequency and variability of phonic stereotypies among children with ASD. Correlations between specific phonic stereotypies and verbal abilities should be investigated further.

- Abstract
Background: Potential overlaps exist between psychopathological features of Anorexia Nervosa (AN) and Autism Spectrum Disorder (ASD). The impact of malnutrition on autistic traits in patients with AN should be considered. This study investigates possible associations among the psychopathology of Eating Disorders (EDs), ASD traits and BMI in a group of young patients with AN, using the EDI-3 (Eating Disorder Inventory-3) test and gold-standard measures for ASD., Methods: Prospective study involving 23 inpatients admitted to an Italian Centre for paediatric ED. ASD traits and ED psychopathology were assessed administering the ADOS-2 (Autism Diagnostic Observation Schedule-2), AQ (Autism Quotient) and EDI-3 tests. Both present and past autistic traits were investigated using different versions of AQ. Correlations were adjusted for BMI, Obsessive Compulsive Disorder (OCD) comorbidity and concurrent antipsychotic treatments., Results: An ASD diagnosis was possible in 22% of patients. Significant correlations were documented between ASD traits and ED psychopathology: AQ total-Interpersonal problems (IPC) (p = 0.041); AQ total-Global psychological maladjustment (GMPC) (p = 0.027); AQ social skills-Ineffectiveness (IC) (p = 0.018); AQ social skills-IPC (p = 0.019); AQ social skills-Affective problems (APC) (p = 0.025); AQ social skills-GMPC (p = 0.007); AQ attention switching-IPC (p = 0.020); ADOS-2 imagination-IC (p = 0.035). These correlations were independent of BMI, OCD and antipsychotic treatments., Conclusions: ASD traits presented high prevalence in a group of young inpatients with AN. These traits were significantly correlated to 4 specific EDI-3 subscales and independent of BMI. This is the first study to investigate the relationship between ASD traits as measured with gold-standard measures, EDI-3 scores, and BMI.

- Abstract
Background: The coronavirus disease 2019 (COVID-19) is currently rare in children and they seem to have a milder disease course and better prognosis than adults. However, SARS-Cov-2 pandemic has indirectly caused problems in pediatric medical assistance. In view of this we wanted to draw a picture of what happened during health emergency and analyze future prospects for restarting., Methods: We involved the Italian pediatric scientific societies institutionally collected in the Italian Federation of Associations and Scientific Societies of the Pediatric Area (FIARPED); We sent a questionnaire to all scientific societies about the pediatric care activity during the COVID-19 emergency and future perspectives for the phase of post-containment., Results: The analysis of the questionnaires showed significant decrease of:admission, outpatient visits and specialist consultancy activities during the COVID-19 emergency, primarily linked to the fear of infection. Instead it was increased the serious degree of diseases admitted. Most of scientific societies maintained the relationship with chronic patients through some form of telemedicine, reporting a strong positive opinion about this modality. Finally showed the need to give life a new approach for hospitalizations and outpatient visits through a greater use of telemedicine, educational programs on families and a more decisive role of family pediatricians., Conclusions: Our study highlighted many aspects that can be improved in pediatric care. We think that It will be necessary a new shared strategy to improve the management and continuity of care for pediatric patients, primarily developing a network of collaboration between families, family pediatrician and hospitals and by enhancing the use of new methods of telecommunications.

- Abstract
Purpose: The aim of this study is to describe demographic data, semiology and etiology in a pediatric population with status epilepticus (SE) and refractory SE (RSE)., Method: We retrospectively reviewed patients with the following inclusion criteria: i) age between two months and eighteen years; ii) SE diagnosis; iii) admission from January 2001 to December 2016; iv) available clinical data., Results: We enrolled 124 patients. Mean and median age was 4.6 ± 4.2 years and 3.3 [1.2-7.5] years respectively. SE had a "de novo" onset in 66.9%. Focal convulsive-SE was the most common semiology (50.8%) whilst generalised (32.3%) and nonconvulsive-SE (NCSE) (16.9%) were less represented. Some etiologies showed a different age distribution: febrile in youngest age (p = 0.002, phi 0.3) and idiopathic-cryptogenic in older children (p = 0.016, phi 0.2). A statistical significance correlation was detected between semiology and etiology (p < 0.001, Cramer's V 0.4), chemotherapy and NCSE (n = 6/21 vs 3/103, p < 0.001) as well as PRES and NCSE (n = 7/21 vs 5/103, p < 0.001). Only 17.7% had a RSE. No correlation was found in demographic and clinical data, but NCSE, acute and idiopathic-cryptogenic etiologies were more frequently associated to RSE. Encephalitis was the most common diagnosis in acute etiologies whereas unknown epilepsy in idiopathic-cryptogenic group., Conclusion: Most of our findings were previously described however we found a significant role of non-antiepileptic treatments (chemotherapy-dialysis) and comorbidity (PRES) determining acute etiology and NCSE. Acute (mostly encephalitis), idiopathic-cryptogenic (mainly unknown-epilepsy) and NCSE were frequently detected in RSE. In the above mentioned conditions a high level of suspicion was recommended., (Copyright © 2020 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.)

- Abstract
Lennox-Gastaut syndrome (LGS) is a severe epileptic encephalopathy with a prevalence of 1-2% of all patients with epilepsy. It is characterized by multiple pharmaco-resistant seizure types, including tonic, atypical absences and tonic or atonic drop attacks, and the presence of electroencephalographic abnormalities, such as slow-spike waves and paroxysmal fast rhythms. Intellectual disability, behavioural and psychiatric disorders are common comorbidities; these disturbances have a multi-factorial pathogenesis. The selection of the most appropriate drug must be tailored to each patient and guided by the prevalent seizure type. In this paper available pharmacological options are discussed and for each pharmacological agent, current evidence of efficacy and tolerability is provided. Valproic acid represents one of the first-line options in the treatment of LGS. Anyway, other antiepileptic drugs (AEDs) may be considered and added: lamotrigine, rufinamide, topiramate, clobazam can be efficacious. The use of felbamate must be carefully evaluated because of its adverse events. Perampanel, zonisamide, levetiracetam and fenfluramine have shown to be useful in the treatment of selected patients; nevertheless, the lack of RCTs does not allow to recommend their use in a systematic way. Recently, cannabidiol has provided high evidence of efficacy against LGS seizures; however, these data must be confirmed by long-term extensive studies and by trials comparing different AEDs, one to each other., (Copyright © 2018 British Epilepsy Association.

- Abstract
Background: Neurofibromatosis type 1 is a genetic disorder associated with cognitive deficits, learning disabilities and behavioral problems. These domains appear to have a still controversial debated association with local areas of T2-hyperintensities on MRI images, called unidentified bright objects (UBOs)., Methods: A cohort of 36 children (aged 7-11 years) included consecutively, underwent neuropsychological and behavioral assessment to determine their cognitive and neuropsychological profile, and the frequency of specific learning disabilities. MRI examination was used to determine the impact of UBOs' presence, number, and location on the cognitive, neuropsychological and behavioral profile, and also the presence of optic glioma., Results: The mean full intelligence quotient was 104.6; only one child had mild intellectual disability. Forty one percent of children had a diagnosis of specific learning disabilities and reading was mainly involved. Twenty per cent had attention problems. All children had normal scores in visuo-motor and visuo-perceptual tests. UBOs were present in 94.0% of the MRI examinations. Two children had optic glioma. Children with UBOs in a specific location and children with UBOs elsewhere were statistically compared, no one of the location seemed to have an impact on general cognition measured with full intelligence quotient. The thalamus was associated with problems in calculation and striatum with behavioral problems. An inverse relationship between the number of UBOs and the full intelligence quotient was present, but without a statistical significance., Conclusions: In this study, the specific location of UBOs did not seem to influence the general cognitive profile and also the relationship between their number and the full intelligence quotient was not significant; these results are still controversial in literature. Finally, the presence of UBOs in the thalamus and striatum may represent a neuroradiological pattern that influences performances in calculation and behavior respectively in children with Neurofibromatosis type 1., (Copyright © 2018.

- Abstract
In the last years, several cases of pediatric epilepsies misdiagnosed and treated as gastrointestinal (GI) disorders have been reported. The aim of this study was to evaluate both frequency and characteristics of these erroneous diagnoses. We identified children who had received a previous misdiagnosis of GI disorder out of 858 consecutive patients with a diagnosis of epilepsy at our hospital from 2010 to 2015. Misdiagnosis was observed in 21 patients (2.4%): 7 children with West syndrome, 10 with temporal lobe epilepsy, and 4 with Panayiotopoulos syndrome. The majority of children with a misdiagnosis (12/21) were younger than 1year at epilepsy onset, and median diagnostic delay was 15.5months. The most frequently diagnosed GI disorder was gastroesophageal reflux disease, especially in younger children. The study confirms that epilepsy in a significant percentage of children is wrongly identified and treated as GI disorders. In particular, epilepsy should be considered in the differential diagnosis of "atypical" gastroesophageal reflux in younger children in order to avoid serious prognostic consequences., (Copyright © 2018 Elsevier Inc.

- Abstract
Most neurogenesis in the mammalian brain is completed embryonically, but in certain areas the production of neurons continues throughout postnatal life. The functional properties of mature postnatally generated neurons often match those of their embryonically produced counterparts. However, we show here that in the olfactory bulb (OB), embryonic and postnatal neurogenesis produce functionally distinct subpopulations of dopaminergic (DA) neurons. We define two subclasses of OB DA neuron by the presence or absence of a key subcellular specialisation: the axon initial segment (AIS). Large AIS-positive axon-bearing DA neurons are exclusively produced during early embryonic stages, leaving small anaxonic AIS-negative cells as the only DA subtype generated via adult neurogenesis. These populations are functionally distinct: large DA cells are more excitable, yet display weaker and - for certain long-latency or inhibitory events - more broadly tuned responses to odorant stimuli. Embryonic and postnatal neurogenesis can therefore generate distinct neuronal subclasses, placing important constraints on the functional roles of adult-born neurons in sensory processing., Competing Interests: EG, EF, MB, AC, DB, VM, MG No competing interests declared, (© 2018, Galliano et al.)

- Abstract
To prevent soiling of marble exposed outdoors, the use of TiO₂ nano-particles has been proposed in the literature by two main routes, both raising durability issues: (i) direct application to marble surface, with the risk of particle leaching by rainfall; (ii) particle incorporation into inorganic or organic coatings, with the risk of organic coating degradation catalyzed by TiO₂ photoactivity. Here, we investigated the combination of nano-TiO₂ and hydroxyapatite (HAP), previously developed for marble protection against dissolution in rain and mechanical consolidation. HAP-TiO₂ combination was investigated by two routes: (i) sequential application of HAP followed by nano-TiO₂ ("H+T"); (ii) simultaneous application by introducing nano-TiO₂ into the phosphate solution used to form HAP ("HT"). The self-cleaning ability was evaluated before and after prolonged exposure to simulated rain. "H+T" and "HT" coatings exhibited much better resistance to nano-TiO₂ leaching by rain, compared to TiO₂ alone. In "H+T" samples, TiO₂ nano-particles adhere better to HAP (having flower-like morphology and high specific surface area) than to marble. In "HT" samples, thanks to chemical bonds between nano-TiO₂ and HAP, the particles are firmly incorporated in the HAP coating, which protects them from leaching by rain, without diminishing their photoactivity and without being degraded by them., Competing Interests: The authors declare no conflict of interest. The founding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.

16. Poly(hydroxyalkanoate)s-Based Hydrophobic Coatings for the Protection of Stone in Cultural Heritage.

- Abstract
Reversibility is a mandatory requirement for materials used in heritage conservation, including hydrophobic protectives. Nevertheless, current protectives for stone are not actually reversible as they remain on the surfaces for a long time after their hydrophobicity is lost and can hardly be removed. Ineffective and aged coatings may jeopardise the stone re-treatability and further conservation interventions. This paper aims at investigating the performance of PHAs-based coatings for stone protection, their main potential being the 'reversibility by biodegradation' once water repellency ended. The biopolymer coatings were applied to three different kinds of stone, representative of lithotypes used in historic architecture: sandstone, limestone and marble. Spray, poultice and dip-coating were tested as coating techniques. The effectiveness and compatibility of the protectives were evaluated in terms of capillary water absorption, static and dynamic contact angles, water vapour diffusion, colour alteration and surface morphology. The stones' wettability after application of two commercial protectives was investigated too, for comparison. Finally, samples were subjected to artificial ageing to investigate their solar light stability. Promising results in terms of efficacy and compatibility were obtained, although the PHAs-based formulations developed here still need improvement for increased durability and on-site applicability., Competing Interests: The authors declare no conflict of interest. The founding sponsors had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, and in the decision to publish the results.

- Abstract
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., (© 2017 John Wiley & Sons A/S.

- Abstract
Synaptic scaling is a key homeostatic plasticity mechanism and is thought to be involved in the regulation of cortical activity levels. Here we investigated the spatial scale of homeostatic changes in spine size following sensory deprivation in a subset of inhibitory (layer 2/3 GAD65-positive) and excitatory (layer 5 Thy1-positive) neurons in mouse visual cortex. Using repeated in vivo two-photon imaging, we find that increases in spine size are tumor necrosis factor alpha (TNF-α) dependent and thus are likely associated with synaptic scaling. Rather than occurring at all spines, the observed increases in spine size are spatially localized to a subset of dendritic branches and are correlated with the degree of recent local spine loss within that branch. Using simulations, we show that such a compartmentalized form of synaptic scaling has computational benefits over cell-wide scaling for information processing within the cell., (Copyright © 2017 The Author(s).

- Abstract
Perampanel is among the latest AEDs approved, indicated for the treatment of partial-onset seizures with or without secondary generalization, and for primary generalized tonic-clonic seizures, in patients aged 12 years and older. This paper summarizes the clinical recommendations on the current role of perampanel in the treatment of pediatric epilepsies and future directions for research. The optimal dosage should be comprised between 4 and 12 mg/day, with 8 mg/day being the most common dosage used. The rate and severity of adverse events, including psychiatric symptoms, can be decreased by starting at low doses, and titrating slowly. Overall, perampanel presents an acceptable risk/benefit ratio, but special caution should be made to the risk of seizure aggravation and behavioral problems. The favorable cognitive profile, the ease of use of the titration scheme and the once-daily formulation offer advantage over other AEDs and make this drug particularly suitable for adolescent population. Perampanel is a welcome addition to the armamentarium of the existing AEDs, as it represents a new approach in the management of epilepsy, with a novel mechanism of action and a potential to have a considerable impact on the treatment of adolescents with epilepsy.

- Abstract
Therapy-related neurotoxicity greatly affects possibility of survival and quality of life of pediatric patients treated for cancer. Central nervous system (CNS) involvement is heterogeneous, varying from very mild and transient symptoms to extremely severe and debilitating, or even lethal syndromes. In this review, we will discuss the broad scenario of CNS complications and toxicities occurring during the treatment of pediatric patients receiving both chemotherapies and hematopoietic stem cell transplantation. Different types of complications are reviewed ranging from therapy related to cerebrovascular with a specific focus on neuroradiologic and clinical features.

- Abstract
Introduction: Status epilepticus (SE) is a life-threatening neurological emergency. SE lasting longer than 120 min and not responding to first-line and second-line antiepileptic drugs is defined as 'refractory' (RCSE) and requires intensive care unit treatment. There is currently neither evidence nor consensus to guide either the optimal choice of therapy or treatment goals for RCSE, which is generally treated with coma induction using conventional anaesthetics (high dose midazolam, thiopental and/or propofol). Increasing evidence indicates that ketamine (KE), a strong N-methyl-d-aspartate glutamate receptor antagonist, may be effective in treating RCSE. We hypothesised that intravenous KE is more efficacious and safer than conventional anaesthetics in treating RCSE., Methods and Analysis: A multicentre, randomised, controlled, open-label, non-profit, sequentially designed study will be conducted to assess the efficacy of KE compared with conventional anaesthetics in the treatment of RCSE in children. 10 Italian centres/hospitals are involved in enrolling 57 patients aged 1 month to 18 years with RCSE. Primary outcome is the resolution of SE up to 24 hours after withdrawal of therapy and is updated for each patient treated according to the sequential method., Ethics and Dissemination: The study received ethical approval from the Tuscan Paediatric Ethics Committee (12/2015). The results of this study will be published in peer-reviewed journals and presented at international conferences., Trial Registration Number: NCT02431663; Pre-results., (Published by the BMJ Publishing Group Limited.

- Abstract
Temple syndrome (TS) is caused by abnormal expression of genes at the imprinted locus 14q32. A subset of TS patients carry 14q32 deletions of paternal origin. We aimed to define possible genotype-phenotype correlations and to highlight the prevalence of thyroid dysfunction, which is a previously unreported feature of TS. We described four new patients who carry deletions of paternal origin at 14q32 detected by array-CGH and reviewed nine patients reported in the medical literature. We compared clinical features with respect to deletion size and position. Expression of DLK1 is altered in all the patients with TS, but intellectual disability (ID) is present only in patients with larger deletions extending proximally to the imprinted locus. This study led to the identification of an ID "critical region" containing four annotated genes including YY1 as the strongest candidate. Furthermore, we described three patients with thyroid dysfunction, which progressed to papillary carcinoma at a very young age in two of them. We conclude that DLK1 loss of function is likely to be responsible for the core features of TS, while haploinsufficiency of a gene outside the imprinted region causes ID. Thyroid cancer may be an unrecognized feature and monitoring for thyroid dysfunction should thus be considered in TS patients., (© 2015 Wiley Periodicals, Inc.)

- Abstract
Background: To evaluate evidence and prognosis of refractory cases of absence seizures., Methods: Subjects with refractory absence seizures were identified retrospectively in 17 Italian epilepsy pediatrics Centers. We analyzed age at onset, family history, presence of myoclonic components, seizure frequency, treatment with antiepileptic drugs (AEDs), interictal electroencephalography (EEG) and neuropsychological assessment. Two subgroups were identified: one with patients with current absence seizures and another with patients that had become seizure free with or without AED treatment. The chi-square test was applied., Results: A total of 92 subjects with drug-resistant absence seizures were analyzed. 45 subjects still show absence seizures (49%) and the other 47 became seizure free (51%) after a period of drug-resistance. The statistical analysis between these two groups showed no correlation between age of onset, family history and abnormalities at interictal EEG. Statistically significant differences were observed with regard to the number of AEDs used and intellectual disability., Conclusion: Typical absence epilepsy classifiable as Childhood Absence Epilepsy could not be considered so "benign", as suggested in literature. A longer duration of disease and a higher frequency of seizure seem to be correlated with a higher presence of cognitive impairment. No significant risk factor was observed to allow the faster and better recognition of patients with worse prognosis., (Copyright © 2015. Published by Elsevier Ltd.)

- Abstract
Background: Duplications of MECP2 gene in males cause a syndrome characterized by distinctive clinical features, including severe to profound mental retardation, infantile hypotonia, mild dysmorphic features, poor speech development, autistic features, seizures, progressive spasticity and recurrent infections. Patients with complex chromosome rearrangements, leading to Xq28 duplication, share most of the clinical features of individuals with tandem duplications, in particular neurologic problems, suggesting a major pathogenetic role of MECP2 overexpression., Results: We performed cytogenetic and molecular cytogenetic studies in a previously described family with affected males showing congenital ataxia, late-onset progressive myoclonic encephalopathy and selective macular degeneration. Microsatellite, FISH and array-CGH analyses identified a recombinant X chromosome with a deletion of the PAR1 region, encompassing SHOX, replaced by a duplicated segment of the Xq28 terminal portion, including MECP2., Conclusions: Our report describes the identification of the actual genetic cause underlying a severe syndrome that previous preliminary analyses erroneously associated to a terminal Xp22.33 region. In the present family as well as in previously reported patients with similar rearrangements, the observed neurologic phenotype is ascribable to MECP2 duplication, with an undefined contribution of the other involved genes. Maculopathy, presented by affected males reported here, could be a novel clinical feature associated to Xq28 disomy due to recombinant X chromosomes, but at present the underlying pathogenetic mechanism is unknown and this potential clinical correlation should be confirmed through the collection of additional patients.

- Abstract
Posterior reversible encephalopathy syndrome (PRES) is a clinical neuroradiologic entity that is becoming increasingly well known and documented in pediatrics. It is characterized by a variable association of seizures, headache, vomiting, altered mental status, visual disturbances, and seizures, as well as imaging suggesting white-gray matter edema involving the posterior regions of the central nervous system in most cases. The pathophysiology of PRES remains unclear. Although PRES has been associated with a widespread range of clinical conditions, namely infections, adverse drug events, autoimmune diseases, and many others, its onset after hematopoietic stem cell and solid organ transplantation remains the most commonly reported. Historically, PRES has proved to be generally reversible and associated with good clinical outcomes; however, severe complications, sometimes life-threatening, can also occur. Most reported cases of childhood PRES after hematopoietic stem cell or solid organ transplantation have been case reports or series across a broad spectrum of different transplant settings, and no clear consensus exists regarding how best to manage the syndrome. Thus, in this article, we provide a comprehensive review of the pathophysiological, clinical, and diagnostic aspects of PRES in children, with a specific focus on the transplant scenario. Differential diagnoses with other neurologic complications after pediatric transplantation are reviewed, and crucial issues in the management of PRES and the development of future research are ultimately addressed., (Copyright © 2015 by the American Academy of Pediatrics.)

- Abstract
Background: Although previous studies indicated a positive association between restrictive anorexia-nervosa (AN-R) and autistic traits, the potential interference of psychiatric internalizing comorbidity on this association is not yet fully investigated., Materials and Methods: The aim of this study was to explore autistic traits and internalizing psychopathology in adolescents (age range: 11.7-17.2 years) with AN-R. Twenty-five patients referred to two tertiary-care hospitals were compared to a large control group (N=170) with no differences in age and sex. AN-R patients and controls filled out instruments assessing autistic traits (autism spectrum quotient [AQ]), psychopathology (youth self-report [YSR] 11-18), and eating patterns (eating attitude test [EAT]). In order to disentangle the possible mediating role of internalizing symptoms on autistic traits, two separate control groups (called True and False healthy control, both composed of 25 eating-problem-free participants) were derived from the whole control group on the basis of the presence or absence of internalizing problems in the YSR., Results: AN-R patients scored significantly higher on AQ compared to the whole control group and to controls without internalizing problems (True HC), but these differences disappeared when only controls with internalizing problems (False HC) were considered., Conclusion: Autistic traits in AN-R individuals may have been overestimated and may partly be due to comorbid internalizing symptoms in investigated patients.

- Abstract
miR-128, a brain-enriched microRNA, has been implicated in the control of neurogenesis and synaptogenesis but its potential roles in intervening processes have not been addressed. We show that post-transcriptional mechanisms restrict miR-128 accumulation to post-mitotic neurons during mouse corticogenesis and in adult stem cell niches. Whereas premature miR-128 expression in progenitors for upper layer neurons leads to impaired neuronal migration and inappropriate branching, sponge-mediated inhibition results in overmigration. Within the upper layers, premature miR-128 expression reduces the complexity of dendritic arborization, associated with altered electrophysiological properties. We show that Phf6, a gene mutated in the cognitive disorder Börjeson-Forssman-Lehmann syndrome, is an important regulatory target for miR-128. Restoring PHF6 expression counteracts the deleterious effect of miR-128 on neuronal migration, outgrowth and intrinsic physiological properties. Our results place miR-128 upstream of PHF6 in a pathway vital for cortical lamination as well as for the development of neuronal morphology and intrinsic excitability.

- Abstract
Prader-Willi syndrome is a multisystemic genetic disorder that can be associated with epilepsy. There is insufficient information concerning the clinical and electroencephalographic characteristics of epilepsy and the long-term outcome of these patients. The aim of this study is to describe seizure types, electroencephalographic patterns and long-term seizure outcome in Prader-Willi syndrome patients suffering from epilepsy. We retrospectively studied 38 patients with Prader-Willi syndrome and seizures. Results of neuroimaging studies were obtained for 35 individuals. We subdivided these patients into two groups: group A, 24 patients, without brain lesions; and group B, 11 patients, with brain abnormalities. All patients were re-evaluated after a period of at least 10 years. Twenty-one patients (55.2 %) were affected by generalized epilepsy and 17 patients (44.8 %) presented focal epilepsy. The most common seizure type was generalized tonic-clonic seizure. The mean age at seizure onset was 4.5 years (ranged from 1 month to 14 years). In the follow-up period, seizure freedom was achieved in 32 patients (84.2 %). Seizure freedom was associated with electroencephalographic normalization, while the six children presenting drug-resistant epilepsy showed persistence of electroencephalographic abnormalities. Group B patients showed a higher prevalence of drug-resistant epilepsy. Patients with Prader-Willi syndrome were frequently affected by generalized seizures. Most of the patients had a favorable evolution, although, patients with brain abnormalities presented a worse outcome, suggesting that the presence of these lesions can influence the response to antiepileptic therapy.

- Abstract
Purpose: To better define the convulsive status epilepticus (CSE) as a possible manifestation at the onset of Panayiotopoulos syndrome (PS) and to assess its prognostic value in these children., Methods: Children with CSE and diagnostic criteria of PS were identified, followed clinically and compared with a group of patients with PS without CSE from 1993 to 2012., Results: We identified 37 patients with CSE at the onset of PS. During the same period we identified 72 children with autonomic symptoms of PS without CSE. The first episode of CSE occurred at a mean age of 6.5 years. Generalized clonic seizures were the most common ictal event and one-third of the patients required admission to Intensive Care Units. Interictal EEGs showed occipital spike activity in 31 (83.7%) subjects. Only 14 (37.8%) patients were treated with valproic acid and for two of them (5.40%) it was necessary to administer other drugs. There were no intractable cases. The overall prognosis was excellent. After the first event, 15 subjects (40.54%) experienced at least another typical PS seizure, but all patients were seizure free at the last follow-up., Conclusion: CSE is not uncommon in PS and it may occur at the onset of benign childhood epilepsy, without leading to a poor prognosis., (Copyright © 2014 British Epilepsy Association.

- Abstract
Background: Although the posterior reversible encephalopathy syndrome (PRES) is considered to have a benign clinical outcome, the presentation of PRES can be associated with life-threatening complications such as severe cerebral hemorrhage, cerebellar herniation and refractory status epilepticus (SE). The aim of this paper is to report incidence, clinical features and outcome of life-threatening complications related to PRES in children., Methods: Patients who suffered from life-threatening complications were retrospectively identified from a group composed by 27 consecutive children diagnosed with PRES in our hospital between 2000 and 2012. The clinical, radiological and EEG features and the outcome of these patients were evaluated and compared to the characteristics of patients with no complications., Results: Five patients (18%) presented life-threatening complications: 2 cerebral hemorrhages with mass effect and midline shift (1 massive intraparenchymal hemorrhage and 1 subdural hemorrhage and intraparenchymal hemorrhage), 2 transforaminal cerebellar herniations and 1 refractory SE. Two children died because of complications and 2 children required urgent neurosurgical intervention. The infratentorial involvement at onset of PRES and the observation of focal neurological deficits other than visual disturbances were significantly more frequent in children with life-threatening complications (p < 0.01)., Conclusions: PRES is associated with a non-negligible incidence of life-threatening complications. A careful clinical, neuroradiological and EEG monitoring is necessary in order to improve the outcome especially in the case of focal neurological deficits and infratentorial involvement., (Copyright © 2014 European Paediatric Neurology Society.

- Abstract
Background: The outcome of benign convulsions associated with gastroenteritis (CwG) has generally been reported as being excellent. However, these data need to be confirmed in studies with longer follow-up evaluations., Aim: To assess the long-term neurological outcome of a large sample of children presenting with CwG., Methods: We reviewed clinical features of 81 subjects presenting with CwG (1994-2010) from three different Italian centers with a follow-up period of at least 3 years., Results: Follow-up period ranged from 39 months to 15 years (mean 9.8 years). Neurological examination and cognitive level at the last evaluation were normal in all the patients. A mild attention deficit was detected in three cases (3.7%). Fourteen children (17.3%) received chronic anti-epileptic therapy. Interictal EEG abnormalities detected at onset in 20 patients (24.7%) reverted to normal. Transient EEG epileptiform abnormalities were detected in other three cases (3.7%), and a transient photosensitivity in one (1.2%). No recurrence of CwG was observed. Three patients (3.7%) presented with a febrile seizure and two (2.5%) with an unprovoked seizure, but none developed epilepsy., Conclusions: The long-term evaluation of children with CwG confirms the excellent prognosis of this condition, with normal psychomotor development and low risk of relapse and of subsequent epilepsy., (Copyright © 2014 European Paediatric Neurology Society.

- Abstract
Loss-of-function mutations in PAK3 contribute to non-syndromic X-linked intellectual disability (NS-XLID) by affecting dendritic spine density and morphology. Linkage analysis in a three-generation family with affected males showing ID, agenesis of corpus callosum, cerebellar hypoplasia, microcephaly and ichthyosis, revealed a candidate disease locus in Xq21.33q24 encompassing over 280 genes. Subsequent to sequencing all coding exons of the X chromosome, we identified a single novel variant within the linkage region, affecting a conserved codon of PAK3. Biochemical studies showed that, similar to previous NS-XLID-associated lesions, the predicted amino acid substitution (Lys389Asn) abolished the kinase activity of PAK3. In addition, the introduced residue conferred a dominant-negative function to the protein that drives the syndromic phenotype. Using a combination of in vitro and in vivo studies in zebrafish embryos, we show that PAK3(N389) escapes its physiologic degradation and is able to perturb MAPK signaling via an uncontrolled kinase-independent function, which in turn leads to alterations of cerebral and craniofacial structures in vivo. Our data expand the spectrum of phenotypes associated with PAK3 mutations, characterize a novel mechanism resulting in a dual molecular effect of the same mutation with a complex PAK3 functional deregulation and provide evidence for a direct functional impact of aberrant PAK3 function on MAPK signaling., (© The Author 2014.

- Abstract
Background/objectives: Restrictive Anorexia nervosa (ANR) is an eating disorder (ED) characterized by a low bone mineral content (BMC) and by an alteration in body composition (reduction and abnormal distribution of fat mass-FM and lean mass-LM). The aim of our study was to address whether bone and body composition changes could be influenced by hormonal status and sport in female adolescents with restrictive anorexia nervosa-ANR., Subjects/methods: Prospective study on 79 adolescents with ANR submitted to Dual Energy X-Ray Absorptiometry-DXA at baseline-T0 and after 12 months-T12. Among the 46/79-58.2% patients that completed the study, we evaluated total and regional FM and LM%, as well as lumbar bone mineral density (BMD) and Z-score, linking them to clinical variables: menarche/amenorrhea/hormonal therapy and physical activity., Results: At T0: body mass index (BMI)=16.4±1.4 kg/m2 with low levels of FM% (21.7±5.7) low BMC in 12/46-26.0% (mean Z-score: -1.21±1.27, with higher values related to physical activity-P=0.001). At T12: a significant increase in BMI-P=0.001, with LM reduction and FM increase (more evident in the trunk-P<0.001); regarding bone, no significant changes were observed, though a tendency in terms of improvement associated with resumption of menses., Conclusions: After 1 year, weight recovery was not associated with a reestablishment of bone values; by contrast, it was associated with an increase and a distortion in FM distribution, more evident in trunk region (potential and adjunctive risk factor for the relapse of the psychiatric condition). The complexity of these clinical findings suggested DXA, a low-dose and low-cost technique, in long-term monitoring of ANR patients.

- Abstract
Purpose: Epileptic seizures are frequent manifestations after hematopoietic stem cell transplantation (HSCT). In this retrospective single-center study we evaluated electroclinical features and analyzed etiologies and outcome of seizures after pediatric HSCT., Methods: Of 261 children transplanted between 2000 and 2010, we identified and analyzed data of 28 patients with seizures within a year from HSCT., Results: Most frequent etiologies were posterior reversible encephalopathy syndrome (PRES, 14 patients) and central nervous system (CNS) infections (4 patients). Seizures were the presentation of the underlying complications in 22 patients. Sixteen episodes of status epilepticus were identified. Seizures secondary to PRES were usually longer and associated with non-convulsive signs. Early neuroimaging and EEG monitoring proved to be crucial to diagnose and treat seizures and their causes. No patients developed epilepsy suggesting that chronic antiepileptic therapy is not necessary in these patients. Overall survival was 32.3% over 5 years in patients with seizures and 45.8% in patients without seizures (p<0.05). Multivariate statistical analysis identified as independent risk factors for seizures a diagnosis of non-oncological disease and cord blood stem cell transplantation., Conclusions: Seizures in transplanted children are a severe event and are associated with high morbidity and poor outcome. In particular, patients with non-oncological diseases and cord blood stem cell transplantation have to be considered at high risk of seizures. Moreover, this study underlines the importance of early recognition of non-convulsive clinical signs and of EEG monitoring for a prompt diagnosis and an appropriate management of seizures and their causes., (Copyright © 2013 British Epilepsy Association.

- Abstract
Objective: To describe the electroclinical features and the long-term outcomes of epilepsy in a large cohort of males and females with Down syndrome who developed epilepsy in childhood., Study Design: Subjects with Down syndrome and cryptogenic epilepsy with onset in childhood were identified retrospectively from the databases of 16 Italian epilepsy centers over a 40-year period. For each subject, age at onset of seizures, seizure semiology and frequency, electroencephalography characteristics, treatment with antiepileptic drugs, and long-term clinical and electroencephalography outcomes were analyzed., Results: A total of 104 subjects (64 males [61.5%], 40 females [38.5%]) were identified. Seizure onset occurred within 1 year of birth in 54 subjects (51.9%), between 1 and 12 years in 42 subjects (40.4%), and after 12 years in 8 subjects (7.7%). Males had a younger age of seizure onset than females. Of the 104 subjects, 51 (49.0%) had infantile spasms (IS), 35 (33.7%) had partial seizures (PS), and 18 (17.3%) had generalized seizures (GS). Febrile seizures were recorded in 5 (4.8%) subjects. Intractable seizures were observed in 23 (22.1%) subjects, including 5 (9.8%) with IS, 8 (44.4%) with PS, and 10 (31.3%) with GS., Conclusion: Cryptogenic epilepsy in Down syndrome may develop during the first year of life in the form of IS or, successively, as PS or GS. Electroclinical features of IS resemble those of idiopathic West syndrome, with a favorable response to treatment with adrenocorticotropic hormone seen. Patients experiencing PS and GS may be resistant to therapy with antiepileptic drugs., (Copyright © 2013 Mosby, Inc. All rights reserved.)

- Abstract
Reports of childhood epilepsies in temporal association with vaccination have had a great impact on the acceptance of vaccination programs by health care providers, but little is known about this possible temporal association and about the types of seizures following vaccinations. For these reasons the Italian League Against Epilepsy (LICE), in collaboration with other Italian scientific societies, has decided to generate Guidelines on Vaccinations and Epilepsy. The aim of Guidelines on Vaccinations and Epilepsy is to present recent unequivocal evidence from published reports on the possible relationship between vaccines and epilepsy in order to provide information about contraindications and risks of vaccinations in patients with epilepsy. The following main issues have been addressed: (1) whether contraindications to vaccinations exist in patients with febrile convulsions, epilepsy, and/or epileptic encephalopathies; and (2) whether any vaccinations can cause febrile seizures, epilepsy, and/or epileptic encephalopathies. Diphtheria-tetanus-pertussis (DTP) vaccination and measles, mumps, and rubella vaccination (MMR) increase significantly the risk of febrile seizures. Recent observations and data about the relationships between vaccination and epileptic encephalopathy show that some cases of apparent vaccine-induced encephalopathy could in fact be caused by an inherent genetic defect with no causal relationship with vaccination., (Wiley Periodicals, Inc. © 2013 International League Against Epilepsy.)

- Abstract
Background: Esophago-gastrointestinal symptoms are frequently reported by patients with eating disorders. Scanty data exist on the relationship between psychopathological traits and digestive complaints., Aims: To prospectively analyze (i) prevalence of digestive symptoms; (ii) psychopathological traits; (iii) relationship between symptom scores and psychopathological profiles., Methods: Psychopathological and digestive symptom questionnaires were completed at baseline, at discharge, at 1 and 6 months' follow-up in 48 consecutive patients (85.4% female, median age, 15 years) hospitalized for eating disorders., Results: The most frequently reported symptoms were postprandial fullness (96%) and abdominal distention (90%). Pooled esophageal (4; IQR 0-14) and gastrointestinal (34; IQR 19-53) symptoms significantly decreased at 6 months' follow-up (1; IQR 0-3 and 10; IQR 4-34; p<0.0001 and p<0.005, respectively). Pooled gastrointestinal symptoms significantly correlated with hypochondriasis (r=0.42, p<0.01). Both esophageal and gastrointestinal symptoms improved in patients with normal values of hypochondriasis and hysteria scales (p<0.05 and p<0.005, respectively) compared to those with pathological traits., Conclusions: Digestive symptoms are frequently reported by patients with eating disorders with their expression and outcome being influenced by psychopathological profiles. Hypochondriasis and hysteria traits are predictive factors for symptomatic improvement., (Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.)

- Abstract
Objectives: The authors present a description of a theater workshop ("Metamorphosis Project"), developed at the Bologna Eating Disorders Center., Design: The workshops are aimed at young, hospitalized patients, and are largely based on the principles of drama therapy. In this article, this therapeutic modality is introduced by a discussion of the theoretical basis for the use of theater in psychiatry from the points of view of several preeminent psychiatrists, including Freud, Winnicott, Klein, and Moreno., Results: Three (3) clinical reports are presented. The satisfaction rate among the first groups of participants was 93%., Conclusions: It is suggested that theater can be useful in decreasing defense mechanisms, allowing a patient-focused approach, mitigating specific symptoms, and improving the quality of life during the hospital stay.

- Abstract
Purpose: This multicenter, prospective study investigates the efficacy and safety of lacosamide adjunctive therapy in pediatric and adult patients with uncontrolled epilepsy., Method: This study was carried out between September 2010 and December 2011 at 16 Italian and 1 German neurologic centers. Lacosamide was added to the baseline therapy at a starting dose of 1 mg/kg/day in patients aged <16 years (group A) and 100 mg daily in subjects aged 16 and older (group B), and titrated to the target dose, ranging from 3 to 12 mg/kg/day or from 100 to 600 mg daily, respectively. After completing the titration period, patients entered a 12-month maintenance period and they were followed up at 3, 6 and 12 months. The primary assessment of efficacy was based on the change from baseline in seizure frequency per 28 days and was evaluated at 3, 6 and 12 months as follows: number and proportion of 100% responders, 50% responders, non-responders and worsening patients. Safety evaluation was also performed at 3, 6 and 12 months., Results: A total of 118 patients (59 group A, 59 group B) with uncontrolled generalized and focal epilepsy were enrolled. Patient mean±SD age was 15.9±6.80 years and the age range was 4-38 years. At 3-month evaluation, of 118 treated patients 56 subjects (47.4% group A; 47.4% group B; p=0.8537) experienced at least a 50% reduction in seizure frequency. At 6 and 12-month follow-up, the 50% responders were 57 (52.5% group A; 44.1% group B; p=0.4612) and 51 (47.4% group A; 39% group B; p=0.4573), respectively. Thirty-five subjects (30.5% group A; 28.8% group B; p=1) experienced side effects during the treatment period. The most common adverse events were dyspepsia for group A and dizziness for group B., Conclusion: Lacosamide may be a useful and safe pharmacological treatment option for both pediatric and adult patients with uncontrolled seizures., (Copyright © 2012 British Epilepsy Association.

- Abstract
Purpose: To describe the clinical and electroencephalographic (EEG) features of reflex myoclonic epilepsy in infancy (RMEI) and long-term cognitive outcome., Methods: We enrolled 31 children from 16 neuropediatric centres in Italy, who underwent clinical and video-EEG evaluation. Cognitive assessment was performed in all patients using standardized psychometric tests., Results: The age at onset ranged from 3 to 24 months of age. Seizures were characterised in all patients by symmetric myoclonic seizures (MS), triggered by sudden unexpected acoustic (38.7%) or tactile stimuli (29%) or both (29%). Spontaneous attacks were reported in 32.2% of the cases. Ictal EEG showed generalized high-amplitude 3 Hz polyspike and wave discharges, synchronous with brief rhythmic bursts of electromyographic activity. Patients were re-evaluated after a period of 7.2 ± 5.6 years. The prognosis for seizure control was excellent in all cases and reflex MS disappeared spontaneously or after valproate treatment. The cognitive outcome was excellent in 90.3% of children., Conclusions: RMEI appears to be a variety of idiopathic generalized epilepsy with specific features that occurs in developmentally normal children., (Copyright © 2012 Elsevier B.V.

- Abstract
Mowat-Wilson syndrome (MWS) is a genetic disease caused by heterozygous mutations or deletions of the ZEB2 gene and is characterized by distinctive facial features, epilepsy, moderate to severe intellectual disability, corpus callosum abnormalities and other congenital malformations. Epilepsy is considered a main manifestation of the syndrome, with a prevalence of about 70-75%. In order to delineate the electroclinical phenotype of epilepsy in MWS, we investigated epilepsy onset and evolution, including seizure types, EEG features, and response to anti-epileptic therapies in 22 patients with genetically confirmed MWS. Onset of seizures occurred at a median age of 14.5 months (range: 1-108 months). The main seizure types were focal and atypical absence seizures. In all patients the first seizure was a focal seizure, often precipitated by fever. The semiology was variable, including hypomotor, versive, or focal clonic manifestations; frequency ranged from daily to sporadic. Focal seizures were more frequent during drowsiness and sleep. In 13 patients, atypical absence seizures appeared later in the course of the disease, usually after the age of 4 years. Epilepsy was usually quite difficult to treat: seizure freedom was achieved in nine out of the 20 treated patients. At epilepsy onset, the EEGs were normal or showed only mild slowing of background activity. During follow-up, irregular, diffuse frontally dominant and occasionally asymmetric spike and waves discharges were seen in most patients. Sleep markedly activated these abnormalities, resulting in continuous or near-to-continuous spike and wave activity during slow wave sleep. Slowing of background activity and poverty of physiological sleep features were seen in most patients. Our data suggest that a distinct electroclinical phenotype, characterized by focal and atypical absence seizures, often preceded by febrile seizures, and age-dependent EEG changes, can be recognized in most patients with MWS., (Copyright © 2013 Wiley Periodicals, Inc.)

- Abstract
Background: The connections between eating disorders (EDs) and alexithymia have not been fully clarified. This study aims to define alexithymia's connections with shame, trauma, dissociation, and body image disorders., Methods: We administered the Dissociative Experience Scale-II, Trauma Symptom Inventory, Experience of Shame Scale, Toronto Alexithymia Scale-20, and Body Uneasiness Test questionnaires to 143 ED subjects. Extensive statistical analyses were performed., Results: The subjects showed higher scores on alexithymia, shame, dissociation, and traumatic feelings scales than the nonclinical population. These aspects are linked with each other in a statistically significant way. Partial correlations highlighted that feelings of shame are correlated to body dissatisfaction, irrespective of trauma or depressed mood. Multiple regression analysis demonstrates that shame (anorexic patients) and perceived traumatic conditions (bulimic and ED not otherwise specified) are associated with adverse image disorders., Conclusion: Shame seems to hold a central role in the perception of an adverse self-image. Alexithymia may be interpreted as being a consequence of previous unelaborated traumatic experiences and feelings of shame, and it could therefore be conceptualized as a maladaptive-reactive construct.

This article describes a case of pyruvate dehydrogenase deficiency in a 3-year-old boy who presented generalized hypotonia, severe psychomotor development delay, and generalized and partial seizures and was refractory to antiepileptic drugs. After the diagnosis, the patient was put on a ketogenic diet. Six months later, seizure frequency was reduced and psychomotor development had improved. At the same time he presented some side effects, such as 2 episodes of significant increases in cholesterol and triglycerides associated with viral respiratory infections. The latter decreased with a supplementation of ω-3 fatty acids and an increase in caloric intake.

- Abstract
The purpose of the study is to explore the causative role of TUBB2B gene mutations in patients with different malformations of cortical development. We collected and evaluated clinical and MRI data of a cohort of 128 consecutive patients (61 females and 67 males) in whom brain MRI had detected a spectrum of malformations of cortical development including polymicrogyria or pachygyria, who were mutation-negative to other possible causative genes. Mutation analysis of the TUBB2B gene was performed. We identified three new TUBB2B mutations in three unrelated patients (3 out of 128; 2.3%) with a diffuse and rather symmetrical cortical abnormality, including diffuse polymicrogyria in two and bilateral regional pachygyria in one. One patient harbored a p.Asp417Asn amino-acid substitution in the C-terminal domain of the protein; one patient a p.Asn256Ser amino-acid substitution in the intermediate domain and one patient a p.Leu117Pro amino-acid substitution in the N-terminal domain. The localization of each mutation within the secondary structure of the β2-tubulin polypeptide suggests that these mutations might alter the proper functions of microtubules. The phenotypic spectrum associated with TUBB2B mutations is wider than previously reported and includes diffuse, symmetric malformations of cortical development.

- Abstract
Activation of innate immune receptors by host-derived factors exacerbates CNS damage, but the identity of these factors remains elusive. We uncovered an unconventional role for the microRNA let-7, a highly abundant regulator of gene expression in the CNS, in which extracellular let-7 activates the RNA-sensing Toll-like receptor (TLR) 7 and induces neurodegeneration through neuronal TLR7. Cerebrospinal fluid (CSF) from individuals with Alzheimer’s disease contains increased amounts of let-7b, and extracellular introduction of let-7b into the CSF of wild-type mice by intrathecal injection resulted in neurodegeneration. Mice lacking TLR7 were resistant to this neurodegenerative effect, but this susceptibility to let-7 was restored in neurons transfected with TLR7 by intrauterine electroporation of Tlr7(−/−) fetuses. Our results suggest that microRNAs can function as signaling molecules and identify TLR7 as an essential element in a pathway that contributes to the spread of CNS damage.
