Long-Term Outcome in Adult Patients with Drug-Resistant Epilepsy Submitted to Vagus Nerve Stimulation.

Epilepsy treatment primarily involves antiseizure medications (ASMs) to eliminate seizures and improve the quality of life, but many patients develop drug-resistant epilepsy (DRE), necessitating alternative interventions. This study aimed to evaluate the long-term efficacy and safety of vagus nerve stimulation (VNS) in managing DRE. We retrospectively analyzed data from 105 adult patients treated at Agostino Gemelli Hospital from 1994 to 2022.

Vagal nerve stimulation cycles alter EEG connectivity in drug-resistant epileptic patients: A study with graph theory metrics.

Objective: Vagal Nerve Stimulation (VNS) is an effective treatment for Drug-Resistant (DR) epilepsy. Albeit the corroborated effectiveness of VNS, little is known about how VNS works. We aim to leverage quantitative Electroencephalography (qEEG) to study how the brain responds to VNS cycles.

Palliative Surgery for Drug-Resistant Epilepsy in Adult Patients. A Systematic Review of the Literature and a Pooled Analysis of Outcomes.

Background: Several types of palliative surgery to treat drug-resistant epilepsy (DRE) have been reported, but the evidence that is available is insufficient to help physicians redirect patients with DRE to the most appropriate kind of surgery.

Methods: A systematic search in the PubMed and Scopus databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to compare different clinical features, outcomes, and complications of adult patients submitted to callosotomy, vagal nerve stimulation, multiple subpial transections, deep brain stimulation, or responsive neurostimulation.

Results: After 3447 articles were screened, 36 studies were selected, including the data of 1628 patients: 76 were treated with callosotomy, 659 were treated with vagal nerve stimulation, 416 were treated with deep brain stimulation, and 477 were treated with responsive neurostimulation.

The surgical treatment of epilepsy.

In 2009, the Commission for Epilepsy Surgery of the Italian League Against Epilepsy (LICE) conducted an overview about the techniques used for the pre-surgical evaluation and the surgical treatment of epilepsies. The recognition that, in selected cases, surgery can be considered the first-line approach, suggested that the experience gained by the main Italian referral centers should be pooled in order to provide a handy source of reference. In light of the progress made over these past years, some parts of that first report have accordingly been updated.

Temporal lobe epilepsy surgery in children and adults: A multicenter study.

Objective: To assess seizure and cognitive outcomes and their predictors in children (<16 years at surgery) and adults undergoing temporal lobe epilepsy (TLE) surgery in eight Italian centers.

Methods: This is a retrospective multicenter study. We performed a descriptive analysis and subsequently carried out multivariable mixed-effect models corrected for multiple comparisons.

Focal Cortical Dysplasia IIIa in Hippocampal Sclerosis-Associated Epilepsy: Anatomo-Electro-Clinical Profile and Surgical Results From a Multicentric Retrospective Study.

Background: Hippocampal sclerosis (HS) may be associated with focal cortical dysplasia IIIa (FCD IIIa) in patients undergoing surgery for temporal lobe epilepsy (TLE).

Objective: To investigate whether the anatomo-electro-clinical profile and surgical outcome in patients with HS-related TLE are affected by coexisting FCD IIIa.

Methods: A total of 220 patients, operated in 5 centers, with at least 24 mo follow-up (FU), were retrospectively studied.

Health Technology Assessment Report on Vagus Nerve Stimulation in Drug-Resistant Epilepsy.

: Vagus nerve stimulation (VNS) is a palliative treatment for medical intractable epileptic syndromes not eligible for resective surgery. Health technology assessment (HTA) represents a modern approach to the analysis of technologies used for healthcare. The purpose of this study is to assess the clinical, organizational, financial, and economic impact of VNS therapy in drug-resistant epilepsies and to establish the congruity between costs incurred and health service reimbursement.

Management of epilepsy in brain tumors.

Epilepsy in brain tumors (BTE) may require medical attention for a variety of unique concerns: epileptic seizures, possible serious adverse effects of antineoplastic and antiepileptic drugs (AEDs), physical disability, and/or neurocognitive disturbances correlated to tumor site. Guidelines for the management of tumor-related epilepsies are lacking. Treatment is not standardized, and overall management might differ according to different specialists.

CD34 Expression in Low-Grade Epilepsy-Associated Tumors: Relationships with Clinicopathologic Features.

Objective: To analyze relationships between CD34 expression and several demographic, clinical, and pathologic features in patients with histopathologic evidence of low-grade epilepsy-associated tumors who underwent epilepsy surgery.

Methods: A retrospective study enrolling 187 patients with low-grade epilepsy-associated tumors who underwent surgery between January 2009 and June 2015 at 8 Italian epilepsy surgery centers was conducted. All cases were histologically diagnosed according to the World Health Organization classification of central nervous system tumors.

Detection of Hyperexcitability by Functional Magnetic Resonance Imaging after Experimental Traumatic Brain Injury.

Diagnosis of ongoing epileptogenesis and associated hyperexcitability after brain injury is a major challenge. Given that increased neuronal activity in the brain triggers a blood oxygenation level-dependent (BOLD) response in functional magnetic resonance imaging (fMRI), we hypothesized that fMRI could be used to identify the brain area(s) with hyperexcitability during post-injury epileptogenesis. We applied fMRI to detect onset and spread of BOLD activation after pentylenetetrazol (PTZ)-induced seizures (PTZ, 30 mg/kg, intraperitoneally) in 16 adult male rats at 2 months after lateral fluid percussion (FPI)-induced traumatic brain injury (TBI).

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.

Epilepsy surgery of "low grade epilepsy associated neuroepithelial tumors": A retrospective nationwide Italian study.

Objective: To analyze the attitude and results of Italian epilepsy surgery centers in the surgical management of "low grade epilepsy associated neuroepithelial tumors" (LEATs).

Methods: We conducted a retrospective study enrolling 339 consecutive patients with LEATs who underwent surgery between January 2009 and June 2015 at eight Italian epilepsy surgery centers. We compared demographic, clinical, pathologic, and surgical features of patients with favorable (Engel class I) and unfavorable (Engel class II, III, and IV) seizure outcome.

Patterns of care of brain tumor-related epilepsy. A cohort study done in Italian Epilepsy Center.

Unlabelled: Epilepsy is the most common comorbidity in patients with brain tumors.

Study Aims: To define characteristics of brain tumor-related epilepsy (BTRE) patients and identify patterns of care. Nationwide, multicenter retrospective cohort study.

Hydroelastic behaviour of a structure exposed to an underwater explosion.

The hydroelastic interaction between an underwater explosion and an elastic plate is investigated num- erically through a domain-decomposition strategy. The three-dimensional features of the problem require a large computational effort, which is reduced through a weak coupling between a one-dimensional radial blast solver, which resolves the blast evolution far from the boundaries, and a three-dimensional compressible flow solver used where the interactions between the compression wave and the boundaries take place and the flow becomes three-dimensional. The three-dimensional flow solver at the boundaries is directly coupled with a modal structural solver that models the response of the solid boundaries like elastic plates.

The detection of neural autoantibodies in patients with antiepileptic-drug-resistant epilepsy predicts response to immunotherapy.

Background And Purpose: The detection of antibodies binding neural antigens in patients with epilepsy has led to the definition of 'autoimmune epilepsy'. Patients with neural antibodies not responding to antiepileptic drugs (AEDs) may benefit from immunotherapy. Aim of this study was to evaluate the frequency of autoantibodies specific to neural antigens in patients with epilepsy and their response to immunotherapy.

The long-term effect of vagus nerve stimulation on quality of life in patients with pharmacoresistant focal epilepsy: the PuLsE (Open Prospective Randomized Long-term Effectiveness) trial.

Objective: To evaluate whether vagus nerve stimulation (VNS) as adjunct to best medical practice (VNS + BMP) is superior to BMP alone in improving long-term health-related quality of life (HRQoL).

Methods: PuLsE (Open Prospective Randomized Long-term Effectiveness) was a prospective, randomized, parallel-group, open-label, and long-term effectiveness study (conducted at 28 sites in Europe and Canada). Adults with pharmacoresistant focal seizures (n = 112) received VNS + BMP or BMP (1:1 ratio).

Functional connectivity MRI and post-operative language performance in temporal lobe epilepsy: initial experience.

Anterior temporal lobectomy is an effective treatment for drug-resistant epilepsy of temporal origin, although new language impairment may develop after surgery. Since correlations between functional connectivity (FC) MRI of the language network and verbal-IQ performance before surgery have recently been reported, we investigated the existence of correlations between the preoperative FC of the language network and post-operative verbal-IQ decline. FC between nodes of the language network of the two hemispheres (Interhemispheric-FC) and within nodes of the left hemisphere (LH-FC) and language lateralization indexes were estimated in five right-handed patients with non-tumoral left temporal lobe epilepsy undergoing anterior temporal lobectomy.

Health Technology Assessment report on the presurgical evaluation and surgical treatment of drug-resistant epilepsy.

Purpose: Epilepsy is a neurologic disorder with major social impact. Surgery is a valuable option in patients who are not responding to antiepileptic drugs. The literature reports demonstrate that a proportion ranging from 40 to 100% of patients with epilepsy achieve seizure remission after surgery.

Overview of presurgical assessment and surgical treatment of epilepsy from the Italian League Against Epilepsy.

The Commission for Epilepsy Surgery of the Italian League Against Epilepsy (LICE) presents an overview of the techniques and methodologies of presurgical evaluation and of the surgical treatment of epilepsies. This overview is the result of the experience developed in the past years in the major Italian centers where programs of epilepsy surgery have been established, and it has the aim of offering a quick and easy reference tool for those involved in the treatment of patients with epilepsy. The sharing of different experiences has the additional aim of conforming and disseminating the employed techniques as well as the methods of selection and evaluation of patients.

Angioarchitectural features of brain arteriovenous malformations associated with seizures: a single center retrospective series.

Background And Purpose: Epileptic seizures account for 24-40% of all clinical onsets in patients with brain arteriovenous malformations (AVMs).

Methods: We retrospectively reviewed the angioarchitectural features of AVMs associated with seizures in 168 patients admitted to our Department from 1997 to 2012. Patients were dichotomized according to demographic characteristics, type of treatment, bleeding occurrence, and morphological and topographic features.

Vagus nerve stimulation in drug-resistant epilepsies. Analysis of potential prognostic factors in a cohort of patients with long-term follow-up.

Background: The results of vagus nerve stimulation (VNS) for the treatment of drug-resistant epilepsies are highly variable due to the lack of defined patient's selection criteria and a follow-up of published studies being generally too short. Here we report the outcome of VNS in a series with long-term follow-up and try to identify subgroups of patients who could be better candidates for this procedure.

Method: We studied 53 patients (33 male, 20 female) with a prospectively recorded follow-up (mean, 55.

Impact of age and co-morbidities in patients with newly diagnosed glioblastoma: a pooled data analysis of three prospective mono-institutional phase II studies.

To analyse the impact of age and co-morbidities on compliance and outcomes in GBM patients enrolled in three prospective phase II trials. GBM patients (≥ 18 years) were treated with radiotherapy (60 Gy) or enrolled in a Fractionated Stereotactic Conformal-Radiotherapy Phase II trial (69.4 Gy).
