On the recovery of disorders of consciousness under intrathecal baclofen administration for severe spasticity-An observational study.

Background: Occasionally, patients show dramatic recovery from disorders of consciousness (DOC) under intrathecal baclofen (ITB), an established treatment option for severe supraspinal spasticity. Anecdotal explanations for ITB-related recovery of cognition include modulation of afferent impulses at the spinal level, thereby reducing spasticity-related proprioceptive information overload within cortico-thalamo-cortical connections.

Objective: In this retrospective patient chart analysis, we assessed whether a reduction in spasticity would be associated with an increase in Coma Recovery Scale revised (CRS-R) scores in a larger sample of patients than previously published.

Complications After Dual Placement of a Baclofen Pump and Ventricular Shunt in Individuals With Severe Brain Injury.

Objective: To assess the complications of dual placement of an intrathecal baclofen (ITB) pump and a ventriculoperitoneal shunt (VPS) in people with severe brain injury.

Design: Case series.

Setting: Referral center, ambulatory, and hospitalized care.

Intrathecal Baclofen in Hereditary Spastic Paraparesis.

Treatment with intrathecal baclofen (ITB) is a therapeutic option in the management of severe spasticity in patients with hereditary spastic paraparesis (HSP). However, information on the impact of ITB on the natural course of disease, especially the effect of ITB on functional parameters over time is limited. We evaluated seven patients with HSP retrospectively who were treated with an ITB device.

Diagnostic and prognostic value of noninvasive long-term video-electroencephalographic monitoring in epilepsy surgery: A systematic review and meta-analysis from the E-PILEPSY consortium.

Objective: The European Union-funded E-PILEPSY network (now continuing within the European Reference Network for rare and complex epilepsies [EpiCARE]) aims to harmonize and optimize presurgical diagnostic procedures by creating and implementing evidence-based guidelines across Europe. The present study evaluates the current evidence on the diagnostic accuracy of long-term video-electroencephalographic monitoring (LTM) in identifying the epileptogenic zone in epilepsy surgery candidates.

Methods: MEDLINE, Embase, CENTRAL, and ClinicalTrials.

Epidemiology of status epilepticus in adults: A population-based study on incidence, causes, and outcomes.

Objective: In 2015, the International League Against Epilepsy (ILAE) proposed a new definition of status epilepticus (SE): 5 minutes of ongoing seizure activity to diagnose convulsive SE (CSE, ie, bilateral tonic-clonic SE) and 10 minutes for focal SE and absence SE, rather than the earlier criterion of 30 minutes. Based on semiology, several types of SE with prominent motor phenomena at any time (including CSE) were distinguished from those without (ie, nonconvulsive SE, NCSE). We present the first population-based incidence study applying the new 2015 ILAE definition and classification of SE and report the impact of the evolution of semiology and level of consciousness (LOC) on outcome.

A further case of familial ring chromosome 20 mosaicism - molecular characterization of the ring and review of the literature.

Ring chromosome 20 syndrome is a rare chromosomal disorder characterized by childhood-onset drug-resistant epilepsy, behavioral problems and variable cognitive impairment. While most cases occur sporadically, parent-to-child transmission of ring 20 mosaicism has only been reported in a few exceptional families. We identified a further family with mother-to-child transmission of ring 20 mosaicism.

Perampanel in patients with refractory and super-refractory status epilepticus in a neurological intensive care unit: A single-center audit of 30 patients.

In refractory status epilepticus (SE), γ-aminobutyric acidergic drugs become less effective and glutamate plays a major role in seizure perpetuation. Data on the efficacy of perampanel (PER) in treatment of refractory SE in humans are limited. Here, we present a single-center case series of patients with refractory SE who received PER orally in an intensive care unit.

Personalized safety measures reduce the adverse event rate of long-term video EEG.

We aimed identifying differences in clinical presentation of SE, etiologies and outcome between patients (pts.

Diagnostic accuracy of the Salzburg EEG criteria for non-convulsive status epilepticus: a retrospective study.

Background: Several EEG criteria have been proposed for diagnosis of non-convulsive status epilepticus (NCSE), but none have been clinically validated. We aimed to assess the diagnostic accuracy of the EEG criteria proposed by a panel of experts at the fourth London-Innsbruck Colloquium on Status Epilepticus in Salzburg, 2013 (henceforth called the Salzburg criteria).

Methods: We did a retrospective, diagnostic accuracy study using EEG recordings from patients admitted for neurological symptoms or signs to three centres in two countries (Danish Epilepsy Centre, Dianalund, Denmark; Aarhus University Hospital, Aarhus, Denmark; and Paracelsus Medical University, Salzburg, Austria).

(S)-Ketamine in Refractory and Super-Refractory Status Epilepticus: A Retrospective Study.

Objective: The aim was to describe the safety and efficacy of (S)-ketamine [(S)-KET] in a series of patients with refractory and super-refractory status epilepticus (RSE and SRSE) in a specialized neurological intensive care unit (NICU).

Methods: We retrospectively analyzed the data of patients with RSE and SRSE treated with (S)-KET in the NICU, Salzburg, Austria, from 2011 to 2015. Data collection included demographic features, clinical presentation, diagnosis, electroencephalogram (EEG) data, anticonvulsant treatment, timing, and duration of treatment with (S)-KET.

Testing patients during seizures: A European consensus procedure developed by a joint taskforce of the ILAE - Commission on European Affairs and the European Epilepsy Monitoring Unit Association.

There is currently no international consensus procedure for performing comprehensive periictal testing of patients in the epilepsy monitoring units (EMUs). Our primary goal was to develop a standardized procedure for managing and testing patients during and after seizures in EMUs. The secondary goal was to assess whether it could be implemented in clinical practice (feasibility).

Perampanel for the treatment of primary generalized tonic-clonic seizures in idiopathic generalized epilepsy.

Introduction: The non-competitive α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) - receptor antagonist perampanel (PER) was approved in 2015 for treatment of primary generalized tonic-clonic seizures (pGTCS). The aim of this narrative review is to summarize available data on pharmacological properties, efficacy and tolerability of PER in pGTCs.

Areas Covered: Data sources included MEDLINE, EMBASE, Google Scholar and ClinicalTrials.

Current practices in long-term video-EEG monitoring services: A survey among partners of the E-PILEPSY pilot network of reference for refractory epilepsy and epilepsy surgery.

Purpose: The European Union-funded E-PILEPSY network aims to improve awareness of, and accessibility to, epilepsy surgery across Europe. In this study we assessed current clinical practices in epilepsy monitoring units (EMUs) in the participating centers.

Salzburg Consensus Criteria for Non-Convulsive Status Epilepticus--approach to clinical application.

Background: Salzburg Consensus Criteria for diagnosis of Non-Convulsive Status Epilepticus (SCNC) were proposed at the 4th London-Innsbruck Colloquium on status epilepticus in Salzburg (2013).

Methods: We retrospectively analyzed the EEGs of 50 consecutive nonhypoxic patients with diagnoses of nonconvulsive status epilepticus (NCSE) at discharge and 50 consecutive controls with abnormal EEGs in a large university hospital in Austria. We implemented the American Clinical Neurophysiology Society's Standardized Critical Care EEG Terminology, 2012 version (ACNS criteria) to increase the test performance of SCNC.

Predicting outcome of status epilepticus.

Background: Status epilepticus (SE) is a frequent neurological emergency complicated by high mortality and often poor functional outcome in survivors. The aim of this study was to review available clinical scores to predict outcome.

Methods: Literature review.

Perampanel in patients with refractory and super-refractory status epilepticus in a neurological intensive care unit.

Introduction: In refractory status epilepticus (SE), because of subcellular maladaptive changes, GABAergic drugs are no longer effective, and the excitatory neurotransmitter glutamate (Glu) plays a major role in seizure perpetuation. Perampanel (PER, licensed since 09/2012) is the first orally active noncompetitive AMPA receptor antagonist for adjunctive treatment of refractory focal epilepsy.

Methods: We analyzed treatment response, seizure outcome, and adverse effects of add-on treatment with perampanel in patients with refractory status epilepticus in the Neurological Intensive Care Unit (NICU), Salzburg, Austria between 09/2012 and 11/2014 by retrospective chart review.

Duration of focal complex, secondarily generalized tonic-clonic, and primarily generalized tonic-clonic seizures--A video-EEG analysis.

Introduction: Identifying seizures with prolonged duration during video-electroencephalographic (EEG) monitoring is of importance to inform clinicians when to start emergency treatment of seizures to prevent status epilepticus. The aims of this study were to assess the clinical and EEG seizure duration (SD) in consecutive patients with epilepsy who underwent prolonged video-EEG monitoring and to identify a seizure type-dependent time point to start emergency treatment based on the likelihood that seizures will not stop spontaneously. Furthermore, we sought to determine predictors of SD and explored the relationship between antiepileptic drug (AED) serum levels and SD.

The demise of Archbishop Wolf Dietrich--A historical note on a fatal status epilepticus documented at Salzburg in 1617.

Introduction: Wolf Dietrich of Raitenau (WD) ruled the archiepiscopal Salzburg from March 2nd 1587 to December 17th 1611. He was condemned by his successor Archbishop Markus Sittikus of Hohenems to spend his last years imprisoned at the Fortress Hohensalzburg, where he died on January 16th 1617. This historical note describes the causes of his death.

A randomized, double-blind comparison of antiepileptic drug treatment in the elderly with new-onset focal epilepsy.

Objective: To compare the effectiveness of controlled-released carbamazepine (CR-CBZ) to levetiracetam (LEV) and to lamotrigine (LTG) in elderly patients with newly diagnosed focal epilepsy.

Methods: Randomized, double-blind, parallel-group trial conducted between January 2007 and August 2011, in 47 ambulatory or hospital sites in Germany, Austria, or Switzerland. Eligible participants were aged ≥ 60, had new-onset epilepsy, had no acute illness as the cause of their seizures, and had no contraindication to the drugs in the trial.

Seizure outcome in 175 patients with juvenile myoclonic epilepsy--a long-term observational study.

Introduction: Juvenile myoclonic epilepsy (JME) is a genetic generalized epilepsy syndrome. Under appropriate antiepileptic drugs (AED) up to 85% of patients become seizure-free, but many may have a relapse after AED withdrawal.

Methods: We retrospectively studied 242 patients with JME at the Department of Neurology, Medical University Innsbruck, Austria (1975-2006).

Epidemiology-based mortality score in status epilepticus (EMSE).

Background: Status epilepticus (SE) is a neurological emergency with high mortality and often a poor functional outcome amongst survivors. So far, only status epilepticus severity score (STESS) is available to predict individual outcomes. STESS is based on weighted sum scores of age, type of seizure, level of consciousness and history of previous seizures.

Infections in status epilepticus: a retrospective 5-year cohort study.

Purpose: Status epilepticus (SE) has attracted renewed interest lately, and efforts are made to optimize every treatment stage. For refractory SE, optimal supporting care involves mechanical ventilation and intensive care unit (ICU) admission. Infections often complicate SE and recently a single-centre observational study demonstrated an association between infections and poor short-term outcome of SE in a cohort of severely ill patients.
