Anticonvulsant effect of glycitin in pentylenetetrazol induced male Wistar rat model by targeting oxidative stress and Nrf2/HO-1 signaling.

Epilepsy, characterized by recurrent seizures, poses a significant health challenge globally. Despite the availability of anti-seizure medications, their adverse effects and inadequate efficacy in controlling seizures propel the exploration of alternative therapeutic measures. In hypothesis, glycitin is a phytoestrogenic compound found in soybeans and due to its estrogenic properties may have anti-epileptic and neuroprotective effects. This study investigates the potential anti-epileptic properties of glycitin in the context of pentylenetetrazol (PTZ) induced seizures in male Wistar rats. The rats were pretreated with varying doses of glycitin (5, 10, and 20 mg/kg) before PTZ (35 mg/kg) administration, and assessments included behavioral observations and histological evaluation via hematoxylin and eosin (H&E) staining. Additionally, oxidative stress markers, such as malondialdehyde (MDA), glutathione peroxidase (GPx), and superoxide dismutase (SOD) levels, were quantified to examine glycitin's impact on oxidative stress. Molecular analysis was conducted to assess the activation of the Nuclear factor erythroid 2-related factor (Nrf2)/Heme oxygenase 1 (HO-1) signaling pathway. Results indicated that glycitin pretreatment effectively mitigated PTZ-induced convulsive behaviors, supported by histological findings from H&E staining. Furthermore, glycitin administration led to significant alterations in MDA, GPx, and SOD levels, suggestive of its ability to modulate oxidative stress. Notably, glycitin treatment induced activation of the Nrf2/HO-1 signaling pathway. These findings underscore the potential of glycitin as an anticonvulsant agent, elucidating its mechanism of action through histological protection, modulation of oxidative stress markers, and activation of the Nrf2/HO-1 signaling pathway.

Emblica officinalis Gaertn as a Potential Alternative Therapy for the Treatment of Epilepsy: An Animal Study.

Introduction: Epilepsy is a neurological disorder characterized by recurrent seizures. Although antiepileptic drugs (AEDs) reduce the frequency of epileptic seizures, they can cause renal and hepatic damage. Several preclinical studies have indicated that Emblica officinalis Gaertn (AMLA) exerts an anticonvulsant effect related to its tannin and polyphenol content. Objective: We aim to evaluate the anticonvulsant effects of chronic oral AMLA administration and its impact on biochemical and hematological parameters in rats. Methods: Twenty-eight male Wistar rats (250 to 300 g) were divided into four experimental groups (n = 7): vehicle (purified water), AMLA (500 and 700 mg/kg), and carbamazepine (CBZ) (300 mg/kg) as the pharmacological control of anticonvulsant activity. Treatments were administered orally every 24 hours for 28 days, while carbamazepine was administered every 48 hours for 5 days before the behavioral, biochemical, and hematological test. On day 29, Status epilepticus (SE) was induced using the lithium-pilocarpine model (3 mEq/kg, i.p. and 30 mg/kg, s.c.), after which the behavioral and biochemical effects were evaluated. Results: The AMLA 500 mg/kg and CBZ 300 mg/kg groups presented fewer phase V seizures than the vehicle group did. None of the treatments modified biochemical or hematological parameters. Conclusion: AMLA could be considered as a potential alternative therapy for the treatment of epilepsy.

Effect of Kruppel-like factor 4 on PTZ-induced acute seizure mice.

Kruppel-like factor 4 (Klf4) is a transcription factor that is involved in neuronal regeneration and the development of glutamatergic systems. However, it is unknown whether Klf4 is involved in acute seizure. To investigate the potential role of Klf4 in pentylenetetrazol (PTZ)-induced seizure, western blotting, immunofluorescence, behaviour test and electrophysiology were conducted in this study. We found that Klf4 protein and mRNA expression were increased in both the hippocampus (HP) and prefrontal cortex (PFC) after PTZ-induced seizure in mice. HP-specific knockout (KO) of Klf4 in mice decreased protein expression of Klf4 and the down-stream Klf4 target tumour protein 53 (TP53/P53). These molecular changes are accompanied by increased seizure latency, reduced immobility time in the forced swimming test and tail suspension test. Reduced hippocampal protein levels for synaptic proteins, including glutamate receptor 1 (GRIA1/GLUA1) and postsynaptic density protein 95 (DLG4/PSD95), were also observed after Klf4-KO, while increased mRNA levels of complement proteins were observed for complement component 1q subcomponent A (C1qa), complement component 1q subcomponent B (C1qb), complement component 1q subcomponent C (C1qc), complement component 3 (C3), complement component 4A (C4a) and complement component 4B (C4b). Moreover, c-Fos expression induced by PTZ was reduced by hippocampal conditional KO of Klf4. Electrophysiology showed that PTZ-induced action potential frequency was decreased by overexpression of Klf4. In conclusion, these findings suggest that Klf4 plays an important role in regulating PTZ-induced seizures and therefore constitutes a new molecular target that should be explored for the development of antiepileptic drugs.

Evaluating the Efficacy of Two Pharmaceutical Therapies for Burning Mouth Syndrome.

Background: Burning mouth syndrome (BMS) is a chronic pain disorder characterized by a persistent burning sensation in the oral cavity, affecting quality of life significantly. Pharmacological therapy is commonly employed in the management of BMS, but the comparative efficacy of different pharmaceutical agents remains uncertain. Materials and Methods: This study was conducted involving 80 participants diagnosed with BMS, randomly assigned to two treatment groups: Group A received tricyclic antidepressants (TCAs), while Group B received anticonvulsants. Baseline assessments of pain intensity, oral health-related quality of life, and psychological distress were conducted using standardized measures. Treatment outcomes were evaluated at 3-month and 6-month follow-up visits. Pain intensity was assessed using a visual analog scale (VAS), while oral health-related quality of life and psychological distress were measured using validated questionnaires. Results: Both treatment groups demonstrated significant improvements in pain intensity, oral health-related quality of life, and psychological distress compared to baseline. At the 6-month follow-up, Group A (TCAs) showed a mean reduction of 70% in pain intensity from baseline, whereas Group B (anticonvulsants) exhibited a mean reduction of 65%. The difference in pain reduction between the two groups was not statistically significant (P = 0.35). Both groups also showed similar improvements in oral health-related quality of life and psychological distress measures. Conclusion: TCAs and anticonvulsants are both effective pharmaceutical therapies for managing BMS, resulting in significant improvements in pain intensity, oral health-related quality of life, and psychological distress.

[Conservative combination therapy of sciatica due to lumbar disc herniation with mechanical physiotherapy (McKenzie), gabapentin, and transforaminal epidural injections]. / Konservative Kombinationstherapie beim lumbalen Bandscheibenvorfall mit Nervenwurzelreizsyndrom mit mechanischer Physiotherapie (McKenzie), Gabapentin und transforaminalen epiduralen Infiltrationen.

BACKGROUND: Treatment of sciatica due to lumbar disc herniation can be surgical or conservative. Conservative management has been described to be effective in 90% of patients; however, in most studies no consistent treatment concept was used. OBJECTIVES: In the present study, we evaluated the effect of a combined nonsurgical management (McKenzie physiotherapy, gabapentin, and periradicular injections) in 40 patients during a 10-day inpatient treatment. METHODS: In addition to the neuro-orthopedic examination, pain severity at rest and after walking were assessed. The Oswestry pain disability scale, the pain severity scale, and the painDETECT scale were examined to assess neuropathic pain components. The duration of incapacity for work and the requirement of a later surgery were recorded. Examinations were performed on the day of admission, on days 3, 6, 10, and 84, 3 months after discharge. RESULTS: During conservative treatment, a continuous reduction of pain and an improvement of the straight leg raise test as well as finger-to-floor distance could be documented. As the three treatment options were introduced with a time delay, it could be demonstrated that all significantly contributed to the improvement. All treatments were tolerated without side-effects and persistent improvement after 12 weeks. On admission, 32% of patients revealed a neuropathic pain component which decreased to 7% at the follow-up. A total of 28 patients showed impaired muscle strength on admission, which decreased to 7 patients on follow-up. Electromyography revealed pathological results in 70% of patients examined. A significant improvement of quality of life (Oswestry Disability Index [ODI]) could be observed and the patients returned to work after 5.8 weeks. Only 3/40 patients required surgical management due to persistent pain. CONCLUSION: The combined nonsurgical operative treatment program is effective and well tolerated.

Drug Rash With Eosinophilia and Systemic Symptoms (DRESS) Due to Multiple Anti-Epileptic Drug Hypersensitivity.

Drug rash with eosinophilia and systemic symptoms (DRESS) is a rare type of hypersensitivity reaction with an incidence in the general population of one case per 10,000, which may lead to life-threatening complications with a mortality rate of 3.8% to 10%. This condition has been characterized by the following symptoms: skin rash, febrile episodes, lymph node enlargement, and involvement of internal organs, specifically the liver. Common medications associated with these reactions are aromatic anticonvulsants and antibiotics. In this paper, we report a case of a 41-year-old female presenting with head-turning to the right and stiffening of the right upper and lower extremities, with subsequent involvement of the left upper and lower extremities secondary to a left frontal lobe glioma. She had a hypersensitivity reaction to five anticonvulsant medications and was treated with prednisone pulse therapy. This case showed that DRESS syndrome may also manifest with newer non-aromatic anticonvulsants such as levetiracetam and that steroid pulse therapy is effective in resolving the elevated blood parameters as well as skin lesions of patients with DRESS syndrome. The patient's epilepsy responded well to gabapentin without any recurrence of seizure episodes or hypersensitivity reactions.

Lamotrigine Emerging as a Driver of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis: An 8-Year Retrospective Study.

BACKGROUND: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) represent severe manifestations of a potentially life-threatening spectrum defined by a desquamating rash of the skin and mucous membranes. This study was prompted by the observed increase in the off-label use of lamotrigine as a causal agent in SJS/TEN in our regional burn center. METHODS: A retrospective cohort of 48 patients presenting to the Connecticut Burn Center from 2015-2022 with suspicion for SJS/TEN were reviewed for age, sex, causative drug, presenting symptoms, hospital course, biopsy confirmation, length of stay, comorbidities, and 30-day mortality. Descriptive statistical analysis was conducted to identify trends in causative agent, clinical presentation, and mortality. RESULTS: Thirty patients in our cohort received a final diagnosis of SJS/TEN. While antibiotics remain the most frequent cause of SJS/TEN across the study period (33.3 %, n = 10), the incidence of cases attributable to lamotrigine increased from 1 case between 2015 and 2018 (6.7 %) to 6 cases between 2019 and 2022 (40 %). In 2020 alone, 50 % of all cases were attributable to lamotrigine (n = 4). Of the patients where lamotrigine was implicated, 71.4 % (n = 5) were prescribed lamotrigine for off-label use in the treatment of non-bipolar mood disorders. The average lamotrigine-associated SJS/TEN patient was younger (p < 0.001), had fewer comorbidities, and was more likely to be female than the general SJS/TEN population. CONCLUSION: Off-label use of lamotrigine is emerging as a major driver of SJS/TEN with notable changes in patient demographics. Further research is necessary to understand how changing trends in the patient population will impact clinical course and optimal management.

A Phase I trial of Non-invasive Ventilation and seizure prophylaxis with levetiracetam In Children with Cerebral Malaria Trial (NOVICE-M Trial).

Background: African children with cerebral malaria and seizures caused Plasmodium falciparum are at greater risk of poor outcomes including death and neurological sequelae. The agonal events are severe hypoventilation and respiratory arrest often triggered by seizures. We hypothesised that prophylactic anti-seizure medication (ASM) could avert 'spikes' of intracranial pressure during or following seizures and that adequate ventilation could be supported by biphasic Cuirass Ventilation (BCV) which requires no intubation. Methods: A Phase I trial conducted in Kilifi, Kenya designed to provide data on safety, feasibility and preliminary data on seizure control using prophylactic ASM (levetiracetam) and BCV as non-invasive ventilatory support in children with cerebral malaria. Children aged 3 months to 12-years hospitalised with P falciparum malaria (positive rapid diagnostic test or a malaria slide), a Blantyre Coma Score ≤2 and a history of acute seizures in this illness are eligible for the trial. In a phased evaluation we will study i) BCV alone for respiratory support (n=10); ii) prophylactic LVT: 40mg/kg loading dose then 30mg/kg every 12 hours given via nasogastric tube for 72 hours (or until fully conscious) plus BCV support (n=10) and; iii) prophylactic LVT: 60mg/kg loading dose then 45mg/kg every 12 hours given via nasogastric tube for 72 hours (or until fully conscious) plus BCV support (n=10). Primary outcome measure: cumulative time with a clinically detected seizures or number of observed seizures over 36 hours. Secondary outcomes will be assessed by feasibility or ability to implement BCV, and recovery from coma within 36 hours. Safety endpoints include: aspiration during admission; death at 28 days and 180 days; and de-novo neurological impairments at 180 days. Conclusions: This is a Phase I trial largely designed to test the feasibility, tolerability and safety of using non-invasive ventilatory support and LVT prophylaxis in cerebral malaria. Registration: ISRCTN76942974 (5.02.2019); PACTR202112749708968 (20.12.2021).

Unfortunately, children with cerebral malaria continue to have very poor outcomes including severe hypoventilation and respiratory arrest (i.e. breathing is too slow or stops) during hospitalization which is often triggered by seizures. We will explore the potential benefits of a special type of ventilation that applies suction or negative pressure to the chest (meaning keeping children breathing by pushing air in and out of their lungs) in combination with anticonvulsants given before children have had any fits We will use a device called biphasic Cuirass Ventilation (BCV) that can be used by non-specialists to help children breath. BCV applies both negative and positive pressure to the chest, covering both inspiration (breathing in) and expiration (breathing out) phases of breathing, which is more appropriate for periods of when the breathing is too slow or stops for a period of time. We will also use an anticonvulsant drug, called levetiracetam to prevent seizures. It has been safely used in Malawian children and shown to improve outcomes. This will be given directly into the stomach via a nasogastric tube (tubes down the nose into the stomach) The study will be carried out at Kilifi County Hospital, Kenya and plans to enrol 30 children aged 3 months to 12 years with cerebral malaria and a positive malaria test The first ten children with have the BCV device only to assist respiration until they recover from their coma. The next twenty children in the trial will have the BCV device in addition with anticonvulsants given before children have had any fits as a preventive strategy to stop fits. All children will have regular monitoring during the period of coma/ventilation and will be followed up on days 28 and 180. The study aims to generate feasibility and safety data to support future trials.

Assessing suicide risk in chronic pain management: a narrative review across drug classes.

INTRODUCTION: Chronic pain presents a multifaceted challenge in clinical practice, necessitating a nuanced understanding of pharmacological interventions to optimize treatment outcomes. This review provides an outline of various pharmacological agents commonly used in chronic pain management and highlights their safety considerations, particularly regarding suicide risk. AREAS COVERED: This review discusses the role of antidepressants, anticonvulsants, GABA receptor agonists, NMDA receptor antagonists, corticosteroids, cannabis and cannabinoids, bisphosphonates, calcitonin, and alpha-2 adrenergic receptor agonists in chronic pain management. It assesses their therapeutic benefits, potential for misuse, and psychiatric adverse effects, including the risk of suicide. Each pharmacological class is evaluated in terms of its efficacy, safety profile, and considerations for clinical practice. We searched peer-reviewed English literature on the topic using the MEDLINE database without time restrictions. EXPERT OPINION: While pharmacological interventions offer promise in alleviating chronic pain, healthcare providers must carefully weigh their benefits against potential risks, including the risk of exacerbating psychiatric symptoms and increasing suicide risk. Individualized treatment approaches, close monitoring, and multidisciplinary collaboration are essential for optimizing pain management strategies while mitigating adverse effects. Ongoing research efforts are crucial for advancing our understanding of these pharmacological interventions and refining pain management practices.

Pharmacological Treatment of Fibromyalgia Syndrome: A Practice-Based Review.

PURPOSE OF REVIEW: Fibromyalgia Syndrome (FMS) is a complex chronic pain condition characterized by widespread musculoskeletal pain and numerous other debilitating symptoms. The purpose of this review is to provide a comprehensive overview, based on everyday clinical practice, of the drugs presently employed in the treatment of FMS. RECENT FINDINGS: The treatment of FMS is based on a multimodal approach, with pharmacologic treatment being an essential pillar. The drugs used include tricyclic antidepressants, serotonin and noradrenaline reuptake inhibitors, other antidepressants, anticonvulsants, myorelaxants, and analgesics. The effectiveness of these medications varies, and the choice of drug often depends on the specific symptoms presented by the patient. Many drugs tend to either address only some domains of the complex FMS symptomatology or have a limited effect on pain. Each treatment option comes with potential side effects and risks that necessitate careful consideration. It may be beneficial to divide patients into clinical subpopulations, such as FMS with comorbid depression, for more effective treatment. Despite the complexities and challenges, the pharmacological treatment remains a crucial part for the management of FMS. This review aims to guide clinicians in prescribing pharmacological treatment to individuals with FMS.

Ketamine reduces seizure and interictal continuum activity in refractory status epilepticus: a multicenter in-person and teleneurocritical care study.

BACKGROUND: There is not a preferred medication for treating refractory status epilepticus (RSE) and intravenous ketamine is increasingly used. Ketamine efficacy, safety, dosage, and influence of other variables on seizure cessation while on ketamine infusions are not well studied. We aimed to characterize ketamine effect on RSE, including interictal activity on electroencephalogram (EEG) and when done by Teleneurocritical care (TNCC). METHODS: We conducted a multicenter, retrospective study from August 2017 to October 2022. Patients 18 years or older who had RSE and received ketamine were included. The primary outcome was effect of ketamine on RSE including interictal activity; secondary outcomes were effect of other variables on RSE, care by TNCC, ketamine infusion dynamics, adverse events, and discharge outcomes. Logistic regression was used. RESULTS: Fifty-one patients from five hospitals met inclusion criteria; 30 patients had RSE and interictal activity on EEG. Median age was 56.8 years (IQR 18.2) and 26% had previously diagnosed epilepsy. Sixteen (31%) patients were treated virtually by TNCC. In those with RSE on EEG, ketamine was added as the fourth antiseizure medication (mean 4.4, SD 1.6). An initial bolus of ketamine was used in 24% of patients (95 mg, IQR 47.5), the median infusion rate was 30.8 mcg/kg/min (IQR 40.4), and median infusion duration was 40 h (IQR 37). Ketamine was associated with 50% cessation of RSE and interictal activity at 24 h in 84% of patients, and complete seizure cessation in 43% of patients. In linear regression, ASMs prior to ketamine were associated with seizure cessation (OR 2.6, 95% CI 0.9-6.9, p = 0.05), while the inverse was seen with propofol infusions (OR 0.02, 95% CI 0.001-0.43, p = 0.01). RSE management by in-person NCC versus virtual by TNCC did not affect rates of seizure cessation. CONCLUSIONS: Ketamine infusions for RSE were associated with reduced seizure burden at 24 h, with 84% of patients having 50% seizure reduction. Similar efficacy and safety was observed irrespective of underlying RSE etiology or when done via TNCC vs in-person NCC.

Valproate encephalopathy: Case series and literature review.

Valproate encephalopathy is one of the unusual and severe but treatable side effect. This research focuses on four female patients who had valproate medication for epilepsy and developed an increased frequency of seizures, exacerbated disruption of consciousness, gastrointestinal problems, cognitive dysfunction, ataxia, and psychobehavioral abnormalities. The patient's symptoms improved over time once sodium valproate was stopped. As a result, when using sodium valproate, one should be aware of the risk of sodium valproate encephalopathy and cease using the medication right once if any of the above symptoms of unknown etiology manifest clinically. We also go over the potential pathogenesis that lead to valproate encephalopathy and the heightened risk of encephalopathy from taking antiepileptic medications together. It was stressed how crucial it is to identify, diagnose, and treat sodium valproate encephalopathy as soon as possible.

Teratogenicity is more likely a function of primary and secondary pharmacology than caused by chemically reactive metabolites: a critical evaluation of 40 years of scientific research.

The number of therapeutic drugs known to be human teratogens is actually relatively small. This may reflect the rigorous animal testing and well defined labelling. Some of these drugs were identified to have reactive metabolites and this has been postulated, historically, to be their teratogenic mechanism. These drugs include thalidomide, various anticonvulsants and retinoic acid derivatives.Many of these experiments were conducted in a period where chemically reactive metabolites were being intensely investigated and associated with all forms of toxicity. The legacy of this is that these examples are routinely cited as well established mechanisms.Examination of mechanism leads to the conclusion that the teratogenicity in humans of these compounds is likely due to the primary and secondary pharmacology of the parent drug and stable circulating metabolites and that association of reactive metabolites to this toxicity is unwarranted.

Short-Term Impact of Seizures and Mitigation Opportunities.

PURPOSE OF REVIEW: The burden of epilepsy is complex and consists of elements directly related to acute seizures as well as those associated with living with a chronic neurologic disorder. The purpose of this systematic review was to characterize short-term burdens of seizures and to explore the potential value of acute treatments to mitigate these burdens apart from reducing the risk of status epilepticus. RECENT FINDINGS: A systematic literature search was conducted using PubMed to identify articles published from January 1, 2017, to June 22, 2023, that described short-term burdens and acute treatments of seizures. Primary outcomes included those related to short-term burdens of seizures and the benefits of acute treatments to reduce short-term burdens. Of the 1332 articles identified through PubMed and 17 through other sources, 27 had relevant outcomes and were included in the qualitative synthesis. Seizure emergencies negatively affected short-term quality of life and the ability to conduct normal daily living activities and were associated with physical (injury) and financial (emergency transport, hospitalization) burdens. The use of acute treatment was associated with a rapid return (≤ 1 h) to normal function/self for both patients and caregivers and potentially lower healthcare utilization and costs. Seizure action plans may improve knowledge and comfort with seizure care, empowering patients and caregivers. The short-term burden of seizures can create a substantial negative impact on patients and caregivers. Acute treatments may reduce the short-term burdens of seizures in addition to their well-described role to reduce seizure activity and the risk for status epilepticus.

Efficacy of second-line anticonvulsant agents with adult status epilepticus: A systematic review and network meta-analysis.

BACKGROUND: Status epilepticus (SE) is potentially life-threatening, however, it is unclear which antiepileptic drugs (AEDs) should be used as second-line AEDs. OBJECTIVE: We conducted a network meta-analysis (NMA) of randomized controlled trials (RCTs) comparing multiple second-line AEDs for SE to investigate the efficacy of AEDs. METHODS: We searched MEDLINE, CENTRAL, ClinicalTrials.gov, and World Health Organization International Clinical Trials Platform Search Portal and included RCTs for patients aged ≥15 years with SE on December 31, 2023. We compared multiple second-line AEDs for SE including fosphenytoin (fPHT), lacosamide (LCM), levetiracetam (LEV), phenytoin (PHT), phenobarbital (PHB), and valproate (VPA). The primary and secondly outcomes were termination of seizures integrating the absence of seizure recurrence at 30 min and 60 min, and adverse events associated with AEDs, respectively, with expressing as relative risk (RR) with a 95% confidence interval (CI). We conducted a NMA using frequentist-based approach with multivariate random effects, and assessed the certainty based on the Grading of Recommendations, Assessment, Development, and Evaluations framework. RESULTS: Seven RCTs (n = 780) were included, and statistically significant difference was detected between VPA vs. PHB (RR, 0.67; 95% CI, 0.53-0.85; very low certainty), fPHT vs. PHB (RR, 0.66; 95% CI, 0.48-0.90; very low certainty), LCM vs. PHB (RR, 0.62; 95% CI, 0.41-0.93; very low certainty), and LEV vs. PHB (RR, 0.69; 95% CI, 0.51-0.94; very low certainty). Moreover, PHB was the highest in the ranking for termination of seizures. For adverse events, no significant reduction was observed owing to the selection of AEDs, although the ranking of PHB was the lowest. CONCLUSIONS: PHB may have been the most effective for seizure termination as second-line AEDs in adult patients with SE. However, the certainty of almost all comparisons was "very low", and careful interpretation is essential.

Anticonvulsants in the Treatment of Behavioral and Psychological Symptoms in Dementia: A Systematic Review.

OBJECTIVES: Behavioral and psychological symptoms of dementia (BPSD) are common and impart a significant burden to patients, caregivers, and the health system. However, there are few pharmacological options for treating BPSD. We conducted a systematic review of clinical trials examining the efficacy of anticonvulsants in BPSD. METHODS: We searched five electronic databases through January 2023, for randomized controlled trials and systematic reviews evaluating the efficacy of non-benzodiazepine anticonvulsants for the treatment of BPSD. We used the Cochrane risk of bias tool to ascertain the risk of bias in included trials. Because statistical pooling of results using meta-analysis was not feasible, we synthesized findings using the Cochrane Synthesis Without Meta-analysis reporting guidelines. RESULTS: We identified 12 studies, including randomized controlled trials (RCTs) and 1 systematic review. Five RCTs evaluating valproic acid were synthesized by a recent Cochrane review which concluded that this drug is likely ineffective for BPSD. We extracted data from 6 trials involving 248 individuals comparing non-benzodiazepine anticonvulsants to either placebo or risperidone. Four trials (n = 97 participants) evaluated carbamazepine, only one of which demonstrated an improvement in the Brief Psychiatric Rating Scale measuring agitation, hostility, psychosis, and withdrawal/depression (effect size: 1.13; 95% confidence interval [CI]: 0.54-1.73) relative to placebo. Adverse effects were more common in patients receiving carbamazepine (20/27; 74%) relative to placebo (5/24; 21%). There is low quality evidence that oxcarbazepine is likely ineffective and that topiramate may be comparable to risperidone. CONCLUSION: Anticonvulsants are unlikely to be effective in BPSD, although the quality of existing evidence is low.

Preconception counselling in women with epilepsy.

Pregnancy and the postpartum period are potentially high-risk periods for women with epilepsy and their babies. All women with epilepsy should have the opportunity for preconception counselling with the aim of reducing risk, optimising outcomes for the potentially developing fetus and enabling informed decision-making. This article provides an evidence-based framework for preconception counselling discussion, including the review of diagnosis and of current antiseizure medication, the risk to the fetus in relation to antiseizure medication and maternal seizures, maternal morbidity, SUDEP risk, folic acid supplements, contraception, breastfeeding and safety advice.

De trastorno neuropsiquiátrico a insulinoma, corrección diagnóstica y resolución mediante resección pancreática mayor / From a neuropsychiatric disorder to the correct diagnosis of insulinoma resolved by major pancreatic resection

RESUMEN El insulinoma es un tumor pancreático poco frecuente con una incidencia del 0,4%, generalmente benigno. Se presenta más frecuentemente en mujeres con una relación 2:1. Es el tumor neuroendocrino funcionante más común del páncreas1, responsable del 70 al 75% de hiperinsulinemía en la práctica clínica. El diagnóstico suele representar un desafío, y el retraso diagnóstico poner en riesgo la vida del paciente. El tratamiento quirúrgico es curativo en más del 90% de los casos; la táctica conservadora, siempre que sea posible, es la de elección. Informamos acerca de una duodenopancreatectomía cefálica (DPC) por insulinoma en un paciente de sexo masculino, con mala interpretación diagnóstica previa de enfermedad neuropsiquiátrica y tratado con anticonvulsivantes.

ABSTRACT Insulinomas are rare pancreatic tumors usually benign with an incidence of 0.4%. They are more common in women with a female-to-male ratio of 2:1. It is the most common functioning neuroendocrine tumor of the pancreas and is responsible for 70-75% of hyperinsulinemia in clinical practice1. The diagnosis is often a challenge, and a delay in diagnosis can have serious consequences for the patient. Surgical treatment is curative in more than 90% of cases, and the conservative approach is the treatment of choice whenever possible. We report the case of a cephalic pancreaticoduodenectomy (CPD) due to an insulinoma in a male patient with a previous misdiagnosis of a neuropsychiatric disorder treated with anticonvulsants.

Assessing the Effectiveness of Eslicarbazepine Acetate in Reducing Audiogenic Reflex Seizures in the GASH/Sal Model of Epilepsy.

Eslicarbazepine acetate (ESL) is a third-generation antiepileptic drug indicated as monotherapy for adults with newly diagnosed epilepsy and as adjunctive therapy for the treatment of partial seizures. Our aim was to assess the effectiveness and safety of both acute and repeated ESL administration against reflex audiogenic seizures, as shown by the Genetic Audiogenic Seizures Hamster from Salamanca (GASH/Sal). Animals were subject to the intraperitoneal administration of ESL, applying doses of 100, 150 and 200 mg/kg for the acute study, whereas a daily dose of 100 mg/kg was selected for the subchronic study, which lasted 14 days. In both studies, the anticonvulsant effect of the therapy was evaluated using neuroethological methods. To assess the safety of the treatment, behavioral tests were performed, hematological and biochemical liver profiles were obtained, and body weight was monitored. In addition, the ESL levels in blood were measured after the acute administration of a 200 mg/kg dose. Treatment with ESL caused a reduction in seizure severity. No statistically significant differences were detected between the selected doses or between the acute or repeated administration of the drug. To summarize, the intraperitoneal administration of ESL is safe and shows an anticonvulsant effect in the GASH/Sal.

A multicenter, matched case-control analysis comparing burden of illness among patients with tuberous sclerosis complex related epilepsy, generalized idiopathic epilepsy, and focal epilepsy in Germany.

BACKGROUND: Depending on the underlying etiology and epilepsy type, the burden of disease for patients with seizures can vary significantly. This analysis aimed to compare direct and indirect costs and quality of life (QoL) among adults with tuberous sclerosis complex (TSC) related with epilepsy, idiopathic generalized epilepsy (IGE), and focal epilepsy (FE) in Germany. METHODS: Questionnaire responses from 92 patients with TSC and epilepsy were matched by age and gender, with responses from 92 patients with IGE and 92 patients with FE collected in independent studies. Comparisons were made across the main QoL components, direct costs (patient visits, medication usage, medical equipment, diagnostic procedures, ancillary treatments, and transport costs), indirect costs (employment, reduced working hours, missed days), and care level costs. RESULTS: Across all three cohorts, mean total direct costs (TSC: €7602 [median €2620]; IGE: €1919 [median €446], P < 0.001; FE: €2598 [median €892], P < 0.001) and mean total indirect costs due to lost productivity over 3 months (TSC: €7185 [median €11,925]; IGE: €3599 [median €0], P < 0.001; FE: €5082 [median €2981], P = 0.03) were highest among patients with TSC. The proportion of patients with TSC who were unemployed (60%) was significantly larger than the proportions of patients with IGE (23%, P < 0.001) or FE (34%, P = P < 0.001) who were unemployed. Index scores for the EuroQuol Scale with 5 dimensions and 3 levels were significantly lower for patients with TSC (time-trade-off [TTO]: 0.705, visual analog scale [VAS]: 0.577) than for patients with IGE (TTO: 0.897, VAS: 0.813; P < 0.001) or FE (TTO: 0.879, VAS: 0.769; P < 0.001). Revised Epilepsy Stigma Scale scores were also significantly higher for patients with TSC (3.97) than for patients with IGE (1.48, P < 0.001) or FE (2.45, P < 0.001). Overall Quality of Life in Epilepsy Inventory-31 items scores was significantly lower among patients with TSC (57.7) and FE (57.6) than among patients with IGE (66.6, P = 0.004 in both comparisons). Significant differences between patients with TSC and IGE were also determined for Neurological Disorder Depression Inventory for Epilepsy (TSC: 13.1; IGE: 11.2, P = 0.009) and Liverpool Adverse Events Profile scores (TSC: 42.7; IGE: 37.5, P = 0.017) with higher score and worse results for TSC patients in both questionnaires. CONCLUSIONS: This study is the first to compare patients with TSC, IGE, and FE in Germany and underlines the excessive QoL burden and both direct and indirect cost burdens experienced by patients with TSC.
