A new tool to assess responsiveness in disorders of consciousness (DoC): a preliminary study on the Brief Post-Coma Scale (BPCS).

Introduction: The Brief Post-Coma Scale (BPCS) is an easy diagnostic tool for individuals with disorders of consciousness (DoC), in a reduced version from a previously Post-Coma Scale, that could distinguish patients in the minimally conscious state (MCS) from those in unresponsive wakefulness syndrome (UWS), formerly defined as vegetative state (VS).

Objective: Aim of the study was to assess the diagnostic validity of the BPCS in comparison with the Coma Recovery Scale-Revised (CRS-R), in its Italian validated version, the Disability Rating Scale (DRS), the Level of Cognitive Functioning (LCF), and the Glasgow Outcome Scale (GOS).

Methods: In an Italian multicenter study on 545 patients with DoC, 36 post-acute rehabilitation wards, 32 long-term care centers, and 2 family associations participated to data collection.

Comparative risk of major congenital malformations with eight different antiepileptic drugs: a prospective cohort study of the EURAP registry.

Background: Evidence for the comparative teratogenic risk of antiepileptic drugs is insufficient, particularly in relation to the dosage used. Therefore, we aimed to compare the occurrence of major congenital malformations following prenatal exposure to the eight most commonly used antiepileptic drugs in monotherapy.

Methods: We did a longitudinal, prospective cohort study based on the EURAP international registry.

Incidence and risk factors of neurosurgical site infections: results of a prospective multicenter cohort study on 6359 surgeries.

Background: Neurosurgical surgical site infections (SSI) are life-threatening complications, requiring medical treatment and additional surgeries and remain a substantial cause of morbidity. In order to identify the incidence and the main risk factors for SSI, we developed the Prophylaxis with Antibiotic Protocol for Neurosurgical Site Infections Study (PASSIS), a prospective observational multicenter cohort study for examining a large number of neurosurgical procedures.

Methods: The study PASSIS involved four Italian departments of neurosurgery applying the same antibiotic prophylaxis (ABP) protocol on 6359 consecutive neurosurgical procedures.

Recessive mutations in VPS13D cause childhood onset movement disorders.

VPS13 protein family members VPS13A through VPS13C have been associated with various recessive movement disorders. We describe the first disease association of rare recessive VPS13D variants including frameshift, missense, and partial duplication mutations with a novel complex, hyperkinetic neurological disorder. The clinical features include developmental delay, a childhood onset movement disorder (chorea, dystonia, or tremor), and progressive spastic ataxia or paraparesis.

Factors influencing the age at onset in familial frontotemporal lobar dementia: Important weight of genetics.

Objective: To quantify the effect of genetic factors and generations influencing the age at onset (AAO) in families with frontotemporal lobar dementia (FTD) due to hexanucleotide repeat expansions and mutations.

Methods: We studied 504 affected individuals from 133 families with repeat expansions and 90 FTD families with mutations in , 2 major genes responsible for FTD and/or amyotrophic lateral sclerosis. Intrafamilial correlations of AAO were analyzed, and variance component methods were used for heritability estimates.

Use of benzodiazepines and cognitive performance in primary care patients with first cognitive complaints.

ABSTRACTThe aim of the present study is to investigate the impact of benzodiazepine use on cognitive performance in primary care patients with first cognitive complaints. The association between the exposition to benzodiazepines (short and long half-life) and cognitive performance, evaluated through the Mini Mental State Examination (MMSE), was tested through analysis of the covariance and logistic regression models. Within the 4,249 participants (mean age 77.

Methodological standards and interpretation of video-electroencephalography in adult control rodents. A TASK1-WG1 report of the AES/ILAE Translational Task Force of the ILAE.

In vivo electrophysiological recordings are widely used in neuroscience research, and video-electroencephalography (vEEG) has become a mainstay of preclinical neuroscience research, including studies of epilepsy and cognition. Studies utilizing vEEG typically involve comparison of measurements obtained from different experimental groups, or from the same experimental group at different times, in which one set of measurements serves as "control" and the others as "test" of the variables of interest. Thus, controls provide mainly a reference measurement for the experimental test.

Maternal and fetal outcomes associated with vagus nerve stimulation during pregnancy.

Objective: To access the effect of vagus nerve stimulation (VNS) on the outcome of pregnancy.

Methods: We used the International Registry of Antiepileptic Drugs and Pregnancy (EURAP) and its network to search for women receiving adjunctive VNS during pregnancy. Data on maternal and fetal outcomes were extracted from the registry databases and outcomes were evaluated.

Mutations of AKT3 are associated with a wide spectrum of developmental disorders including extreme megalencephaly.

Mutations of genes within the phosphatidylinositol-3-kinase (PI3K)-AKT-MTOR pathway are well known causes of brain overgrowth (megalencephaly) as well as segmental cortical dysplasia (such as hemimegalencephaly, focal cortical dysplasia and polymicrogyria). Mutations of the AKT3 gene have been reported in a few individuals with brain malformations, to date. Therefore, our understanding regarding the clinical and molecular spectrum associated with mutations of this critical gene is limited, with no clear genotype-phenotype correlations.

Increasing volume and complexity of pediatric epilepsy surgery with stable seizure outcome between 2008 and 2014: A nationwide multicenter study.

Objective: The objective of the study was to assess common practice in pediatric epilepsy surgery in Italy between 2008 and 2014.

Methods: A survey was conducted among nine Italian epilepsy surgery centers to collect information on presurgical and postsurgical evaluation protocols, volumes and types of surgical interventions, and etiologies and seizure outcomes in pediatric epilepsy surgery between 2008 and 2014.

Results: Retrospective data on 527 surgical procedures were collected.

Prevalence and orthopedic management of foot and ankle deformities in Charcot-Marie-Tooth disease.

Introduction: Foot deformities are frequent complications in Charcot-Marie-Tooth disease (CMT) patients, often requiring orthopedic surgery. However, there are no prospective, randomized studies on surgical management, and there is variation in the approaches among centers both within and between countries.

Methods: In this study we assessed the frequency of foot deformities and surgery among patients recruited into the Inherited Neuropathies Consortium (INC).

Role of anticholinergic burden in primary care patients with first cognitive complaints.

Background And Purpose: Drugs with anticholinergic properties might have a negative impact on cognition, but findings are still conflicting. The association was evaluated between anticholinergic drugs and cognitive performance in primary care patients with first cognitive complaints.

Methods: From April 2013 to March 2014, 353 general practitioners administered the Mini-Mental State Examination (MMSE) to patients presenting with first cognitive complaints.

ATXN2 trinucleotide repeat length correlates with risk of ALS.

We investigated a CAG trinucleotide repeat expansion in the ATXN2 gene in amyotrophic lateral sclerosis (ALS). Two new case-control studies, a British dataset of 1474 ALS cases and 567 controls, and a Dutch dataset of 1328 ALS cases and 691 controls were analyzed. In addition, to increase power, we systematically searched PubMed for case-control studies published after 1 August 2010 that investigated the association between ATXN2 intermediate repeats and ALS.

16p13 microduplication without CREBBP involvement: Moving toward a phenotype delineation.

The short arm of chromosome 16 is one of the less stable regions of our genome, as over 10% of the euchromatic region of 16p is composed of highly complex low copy repeats that are known to be predisposed to rearrangements mediated by non-allelic homologous recombination. The 16p13.3p13.

Automated double-cone-beam CT fusion technique. Enhanced evaluation of glue distribution in cases of spinal dural arteriovenous fistula (SDAVF) embolisation.

Objectives: Spinal dural arteriovenous fistulas (SDAVFs) are acquired diseases that represent the majority of all arteriovenous spinal shunts, leading to progressive and disabling myelopathy. Treatment is focused on accurately disconnecting the fistula point. We present our experience with the double-cone-beam CT fusion technique successfully applied to evaluate treatment results in a series of SDAVFs.

(123) I-2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl) nortropane single photon emission computed tomography and (123) I-metaiodobenzylguanidine myocardial scintigraphy in differentiating dementia with lewy bodies from other dementias: A comparative study.

Objective: To compare the diagnostic value of striatal (123) I-2β-carbomethoxy-3β-(4-iodophenyl)-N-(3-fluoropropyl) nortropane ((123) I-FP-CIT) single photon emission computed tomography (SPECT) and (123) I-metaiodobenzylguanidine ((123) I-MIBG) myocardial scintigraphy in differentiating dementia with Lewy bodies (DLB) from other dementia types.

Methods: This prospective longitudinal study included 30 patients with a clinical diagnosis of DLB and 29 patients with non-DLB dementia (Alzheimer disease, n = 16; behavioral variant frontotemporal dementia, n = 13). All patients underwent (123) I-FP-CIT SPECT and (123) I-MIBG myocardial scintigraphy within a few weeks of clinical diagnosis.

Withdrawal of valproic acid treatment during pregnancy and seizure outcome: Observations from EURAP.

Based on data from the EURAP observational International registry of antiepileptic drugs (AEDs) and pregnancy, we assessed changes in seizure control and subsequent AED changes in women who underwent attempts to withdraw valproic acid (VPA) during the first trimester of pregnancy. Applying Bayesian statistics, we compared seizure control in pregnancies where VPA was withdrawn (withdrawal group, n = 93), switched to another AED (switch group, n = 38), or maintained (maintained-therapy group, n = 1,588) during the first trimester. The probability of primarily or secondarily generalized tonic-clonic seizures (GTCS) was lower in the maintained-therapy group compared with the other two groups, both in the first trimester and for the entire duration of pregnancy.

Multimodal study of default-mode network integrity in disorders of consciousness.

Objective: Understanding residual brain function in disorders of consciousness poses extraordinary challenges, and imaging examinations are needed to complement clinical assessment. The default-mode network (DMN) is known to be dysfunctional, although correlation with level of consciousness remains controversial. We investigated DMN activity with resting-state functional magnetic resonance imaging (rs-fMRI), alongside its structural and metabolic integrity, aiming to elucidate the corresponding associations with clinical assessment.

Liver transplant in ethylmalonic encephalopathy: a new treatment for an otherwise fatal disease.

Ethylmalonic encephalopathy is a fatal, rapidly progressive mitochondrial disorder caused by ETHE1 mutations, whose peculiar clinical and biochemical features are due to the toxic accumulation of hydrogen sulphide and of its metabolites, including thiosulphate. In mice with ethylmalonic encephalopathy, liver-targeted adeno-associated virus-mediated ETHE1 gene transfer dramatically improved both clinical course and metabolic abnormalities. Reasoning that the same achievement could be accomplished by liver transplantation, we performed living donor-liver transplantation in an infant with ethylmalonic encephalopathy.

International recommendation for a comprehensive neuropathologic workup of epilepsy surgery brain tissue: A consensus Task Force report from the ILAE Commission on Diagnostic Methods.

Epilepsy surgery is an effective treatment in many patients with drug-resistant focal epilepsies. An early decision for surgical therapy is facilitated by a magnetic resonance imaging (MRI)-visible brain lesion congruent with the electrophysiologically abnormal brain region. Recent advances in the pathologic diagnosis and classification of epileptogenic brain lesions are helpful for clinical correlation, outcome stratification, and patient management.
