Educational needs and career development of young epileptologists in Italy.

OBJECTIVE: The Education and Career Task Force of the Young Epilepsy Section-Italy focuses on educational and career development needs of young Italian epileptologists. Two surveys were developed (pre- and post COVID-19 pandemic) in order to identify the needs of members of the Lega Italiana Contro l'Epilessia under 40 years of age. METHODS: The first was distributed during the 42nd National Congress (Rome, June 5-7, 2019); the second during the 45th National Congress (Padova, June 8-10, 2022) and subsequently by e-mail until July 9, 2022. Data from the 2019 survey were analyzed descriptively. Data from the 2022 survey were further analyzed with Pearson's chi-square test to establish if gender, field of clinical practice, and professional role were associated with different needs. RESULTS: Sixty surveys were completed in 2019 and 69 in 2022. Attendance to courses and congresses as the preferred way to keep medical knowledge updated reduced between 2019 and 2022. The reason was different between trainees (mostly elevated costs) and early-career consultants (mostly organizational issues) (p = 0.005). The main needs for improvement also diverged: trainees indicated differential diagnosis and diagnostic approach to the first seizure while consultants indicated diagnostic approach to genetic epilepsies (p = 0.004); in the genetic field, priority needs were selection of genetic investigations for trainees versus genotype-phenotype correlations for consultants (p = 0.022). The field of practice (pediatric vs. adult) also impacted on the main needs for improvement that is, acquisition of expertise in neuroradiology and drug therapy for pediatric versus genetics for adult neurology trainees or consultants (p = 0.018); in the clinical area, differential diagnosis and approach to the first seizure versus status epilepticus (p = 0.027); in the genetic field, precision medicine versus genotype-phenotype correlations (p = 0.034). No differences were found based on gender. SIGNIFICANCE: The surveys identified different needs based on professional role and discipline. PLAIN LANGUAGE SUMMARY: The Education and Career Task Force of the Young Epilepsy Section-Italy (YES-I) launched two surveys among young Italian epileptologists. Our research shows that the educational and professional needs of young Italian epileptologists vary based on their job role and field of practice, but not on gender. Their preference for on-site congresses and courses reduced after the pandemic, and the main reason is linked to financial constraints for trainees and to organizational issues for consultants. The main expectation toward YES-I is to receive support for education and career development. Thus, we collected useful suggestions on how to organize our future YES-I activities.

Use, experience and perspectives of high-density EEG among Italian epilepsy centers: a national survey.

INTRODUCTION: High-density EEG (hdEEG) is a validated tool in presurgical evaluation of people with epilepsy. The aim of this national survey is to estimate diffusion and knowledge of hdEEG to develop a network among Italian epilepsy centers. METHODS: A survey of 16 items (and 15 additional items) was distributed nationwide by email to all members of the Italian League Against Epilepsy and the Italian Society of Clinical Neurophysiology. The data obtained were analyzed using descriptive statistics. RESULTS: A total of 104 respondents were collected from 85 centers, 82% from the Centre-North of Italy; 27% of the respondents had a hdEEG. The main applications were for epileptogenic focus characterization in the pre-surgical evaluation (35%), biomarker research (35%) and scientific activity (30%). The greatest obstacles to hdEEG were economic resources (35%), acquisition of dedicated personnel (30%) and finding expertise (17%). Dissemination was limited by difficulties in finding expertise and dedicated personnel (74%) more than buying devices (9%); 43% of the respondents have already published hdEEG data, and 91% of centers were available to participate in multicenter hdEEG studies, helping in both pre-processing and analysis. Eighty-nine percent of respondents would be interested in referring patients to centers with established experience for clinical and research purposes. CONCLUSIONS: In Italy, hdEEG is mainly used in third-level epilepsy centers for research and clinical purposes. HdEEG diffusion is limited not only by costs but also by lack of trained personnel. Italian centers demonstrated a high interest in educational initiatives on hdEEG as well as in clinical and research collaborations.

Autoimmune encephalitis during pregnancy: A diagnostic and therapeutic challenge-A systematic review with individual patients' analysis and clinical recommendations.

Several reports have described the autoimmune encephalitis' (AE) possible onset during pregnancy. In this systematic review, we summarize the available data on the diagnostic and therapeutic approach to AE during pregnancy, highlighting the associated maternal and fetal clinical outcomes. A systematic search of the literature was performed. The following databases were used: PubMed, Google Scholar, EMBASE, and CrossRef. The revision was registered on the PROSPERO platform (CRD42022336357). Forty-nine patients were included. AE onset was mainly observed during the first and the second trimester of pregnancy with psychiatric manifestations and seizures as main onset symptoms. CSF analysis showed AE-specific autoantibody positivity in 33 patients (anti-NMDA receptor as the most frequent). EEG generally showed normal findings. MRI revealed pathological findings in less than half of patients. Tumor screening was positive in 14 cases. First-line immunotherapy (single or combined) was generally employed while second line was administered in a minority of patients. Levetiracetam was the most used antiseizure medication. Cesarean section was performed in 18 women. Most of the women had an excellent early outcome after delivery but 22 showed persistent neurological deficits in long-term follow-up. Fetal outcome was positive in 33 cases, whereas 12 cases of fetal death were reported. A logistic regression showed that no variable significantly influenced the odds of good/bad maternal and fetal clinical outcome. Diagnosis and treatment of AE during pregnancy is challenging. The rate of miscarriage in women with AE seems to be higher than the general population. In addition, mothers may show long-term neurological deficits.

Psychogenic non-epileptic seizures (PNES) in the COVID-19 pandemic era: A systematic review with individual patients' analysis.

OBJECTIVE: Psychogenic non-epileptic seizures (PNES) resemble epileptic seizures but are not due to underlying epileptic activity and in some cases coexist alongside epilepsy. We described the clinical characteristics of patients with PNES as reported in the literature from the outbreak of the COVID-19 pandemic. We evaluated differences between patients with a diagnosis made immediately before the pandemic (pPNES) and those newly diagnosed during it (nPNES). METHODS: A systematic search with individual patient analysis of PNES cases published since the COVID-19 pandemic outbreak was performed. Differences between pPNES and nPNES were analyzed using Chi-square or Fisher exact test. RESULTS: Eleven articles were included, with 133 patients (106 pPNES and 27 nPNES). In the pPNES group, PNES frequency increased during the pandemic in 20/106 patients, whereas in 78/106, the frequency remained stable or decreased. nPNES was associated with higher risks of SARS-CoV-2 infection and epilepsy diagnosis, whereas psychiatric comorbidities were less frequent. CONCLUSIONS: During the pandemic, most patients with pPNES remained stable or improved, whereas nPNES was associated with a lower burden of psychiatric comorbidities. These intriguing findings suggest that, at least in some patients, the COVID-19 pandemic may not necessarily lead to worsening in the frequency of PNES and quality of life.

Treatment and care of women with epilepsy before, during, and after pregnancy: a practical guide.

Women with epilepsy (WWE) wishing for a child represent a highly relevant subgroup of epilepsy patients. The treating epileptologist needs to delineate the epilepsy syndrome and choose the appropriate anti-seizure medication (ASM) considering the main goal of seizure freedom, teratogenic risks, changes in drug metabolism during pregnancy and postpartum, demanding for up-titration during and down-titration after pregnancy. Folic acid or vitamin K supplements and breastfeeding are also discussed in this review. Lamotrigine and levetiracetam have the lowest teratogenic potential. Data on teratogenic risks are also favorable for oxcarbazepine, whereas topiramate tends to have an unfavorable profile. Valproate needs special emphasis. It is most effective in generalized seizures but should be avoided whenever possible due to its teratogenic effects and the negative impact on neuropsychological development of in utero-exposed children. Valproate still has its justification in patients not achieving seizure freedom with other ASMs or if a woman decides to or cannot become pregnant for any reason. When valproate is the most appropriate treatment option, the patient and caregiver must be fully informed of the risks associated with its use during pregnancies. Folate supplementation is recommended to reduce the risk of major congenital malformations. However, there is insufficient information to address the optimal dose and it is unclear whether higher doses offer greater protection. There is currently no general recommendation for a peripartum vitamin K prophylaxis. During pregnancy most ASMs (e.g. lamotrigine, oxcarbazepine, and levetiracetam) need to be increased to compensate for the decline in serum levels; exceptions are valproate and carbamazepine. Postpartum, baseline levels are reached relatively fast, and down-titration is performed empirically. Many ASMs in monotherapy are (moderately) safe for breastfeeding and women should be encouraged to do so. This review provides a practically oriented overview of the complex management of WWE before, during, and after pregnancy.

Exploring the Evidence for Broad-Spectrum Effectiveness of Perampanel: A Systematic Review of Clinical Data in Generalised Seizures.

BACKGROUND: The effectiveness of adjunctive perampanel has not been systematically assessed in seizure types other than its approved indications of focal seizures and primary generalised tonic-clonic seizures (PGTCS) in idiopathic generalised epilepsies (IGEs). OBJECTIVE: We aimed to identify and review available evidence on outcomes with perampanel in generalised seizures and epilepsies to examine its potential as a broad-spectrum anti-seizure medication. METHODS: Bibliographic databases of publications, clinical trials, and conference abstracts were searched up to August 2020 to identify studies reporting seizure or safety outcomes in patients of any age, with any type of epilepsy-associated generalised seizures treated with perampanel. Data extracted from selected records were tabulated by seizure type and syndrome, and analysed qualitatively (PROSPERO protocol CRD42020201564). RESULTS: Ninety-one reports met inclusion criteria and were selected: 15 reports of 1 randomised controlled trial (RCT), 8 reports of 4 non-randomised interventional studies, 37 reports of observational studies, 21 case reports and 10 systematic reviews and meta-analyses. Extracted data included 359 patients with PGTCS of any aetiology, 251 with myoclonic seizures, 112 with absence seizures, 50 with tonic seizures and 32 children with epileptic spasms. The most commonly reported epilepsy type was IGE (N = 378) and the most common syndromes were juvenile myoclonic epilepsy (N = 92), progressive myoclonic epilepsies (N = 59) and absence epilepsies (N = 43). The RCT provided Class I evidence of the efficacy and tolerability of adjunctive perampanel for PGTCS in patients aged ≥ 12 years with IGE. Data from other studies provides weaker (observational) evidence of its effectiveness in multiple generalised seizure types, including myoclonic, absence and tonic seizures. There were no patterns suggesting seizure worsening or aggravation in any seizure or epilepsy type. CONCLUSIONS: The identified studies suggest the potential of perampanel as a broad-spectrum antiseizure medication. Much of the available data, however, come from non-randomised, non-controlled studies and are open to high risk of bias. Further studies are warranted to provide more robust evidence.

Status epilepticus and COVID-19: A systematic review.

PURPOSE: In March 2020, the World Health Organization declared the SARS-CoV-2 infection-related coronavirus Disease (COVID-19) a pandemic. During the first and second waves of the pandemic spread, there have been several reports of COVID-19-associated neurological manifestations, including acute seizures and status epilepticus (SE). In this systematic review, we summarized the available data on clinical features, diagnosis, and therapy of COVID-19-related SE. METHODS: We performed a systematic search of the literature to identify data on demographics, clinical, neurophysiological, and neuroradiological data of patients with COVID-19-related SE. We used regression models (linear or logistic) with a stepwise forward method to identify features associated with mortality or severity of SE. RESULTS: Thirty-nine articles were included with a total of 47 cases of SE associated with COVID-19. Age, time between the acute respiratory phase of SARS-CoV-2 infection and SE onset, and hospitalization correlated with a higher SE severity as assessed by quantitative validated scales. CONCLUSIONS: SE can be a neurological manifestation of SARS-CoV-2 infection. Although a possible association between SE and COVID-19 has been reported, the exact mechanisms are still not fully understood. Systemic inflammatory syndrome due to cytokine release could play a role in COVID-19-related SE.

Statins in primary prevention of poststroke seizures and epilepsy: A systematic review.

INTRODUCTION: Cerebrovascular disease is the most common cause of seizures in adults and the elderly. So far, no drug is recommended as primary prevention of acute symptomatic poststroke seizures (ASPSS) or poststroke epilepsy (PSE). This systematic review aimed to evaluate the association between the use of statins after stroke and the risk of developing ASPSS or PSE following cerebral infarct or hemorrhage (primary prevention). METHODS: We included studies evaluating the poststroke use of statins as primary prevention of ASPSS or PSE, irrespective of stroke type. We excluded uncontrolled studies and studies with prestroke statin use. The main outcome included the occurrence of ASPSS or PSE and the effect of statins by type and dose. The odds ratios (ORs) or hazard ratios (HR) with 95% confidence intervals (CIs) were used as the measures of association between treatment and outcome. RESULTS: Four studies were included. One study showed a reduced risk of ASPSS after ischemic stroke (OR: 0.25; 95% CI: 0.10-0.59; p = 0.0016). Three studies consistently reported a reduced risk of PSE after ischemic stroke, and one study a reduced risk of PSE after hemorrhagic stroke (HR: 0.62; 95% CI: 0.42-0.90; p = 0.01). CONCLUSIONS: Data from the literature suggest an association between statin use and a reduced risk of ASPSS after ischemic stroke and a reduced risk of PSE after ischemic and hemorrhagic stroke. Although the certainty of the evidence is low, these findings appear promising and worthy of further investigation.
