Eslicarbazepine acetate (ESL, Aptiom™) is a once-daily anticonvulsant, approved as adjunctive treatment of partial-onset seizures (POS). Historical-controlled trials investigating the use of ESL as monotherapy have demonstrated a favorable efficacy and tolerability profile in patients with POS. This prospective, non-interventional study recruited POS patients in 17 hospitals in Spain. After a 3-month baseline period, ESL therapy was initiated as 400mg QD and up-titrated to an optimal maintenance dose based on clinical response and tolerance...

There are many theories explaining vitiligo such as genetic, autoimmune, neural, free radicals, biochemical, intrinsic defect, melanocytorrhagy and convergent theories. Phenytoin is a widely used anticonvulsant, which is used in cutaneous medicine for treatment of ulcers and epidermolysis bullosa. The aim of this study is to assess the effectiveness of topical phenytoin gel in treatment of vitiligo patients and explaining the underlying mechanism using immunohistochemistry for evaluation of HMB45, CD4 and CD8...

BACKGROUND: Valproic acid (VPA) is the most teratogenic anticonvulsant drug in clinical use today. Children exposed prenatally to VPA have previously been shown to have dysmorphic craniofacial features, identified subjectively but not by anthropometric methods. Exposure to VPA has also been associated with an increased frequency of autism spectrum disorder (ASD). An increased cephalic index (the ratio of the cranial lateral width to the cranial anterior-posterior length) has been observed in children with ASD...

Pain is frequent and underreported among HIV+ women. We determined occurrence and severity of pain, and types of pain treatments used among HIV+ and HIV- women. Cross-sectional analyses of pain as measured by the Brief Pain Inventory Short Form, and related pain therapies nested in the Women's Interagency HIV Study (WIHS). Multiple variable linear regression models examined differences by HIV status in pain severity and pain interference in general activity, mood, ability to walk, work, relationships with others, sleep, and enjoyment of life...

Cannabidiol (CBD) is a phytocannabinoid that has demonstrated anticonvulsant efficacy in several animal models of seizure. The current experiment validated CBD's anticonvulsant effect using the acute pentylenetetrazol (PTZ) model. Furthermore, it tested whether CBD reduces seizure activity by interacting with either the serotonergic 5HT1A or 5HT2A receptor. 120 male adolescent Wistar-Kyoto rats were randomly assigned to 8 treatment groups in two consecutive experiments. In both experiments, subjects received either CBD (100mg/kg) or vehicle 60min prior to seizure testing...

Ghrelin, an orexigenic peptide synthesized by endocrine cells of the gastric mucosa, plays a major role in inhibiting seizures. However, the underlying mechanism of ghrelin's anticonvulsant action is still unclear. Nowadays, there are considerable evidences showing that ghrelin is implicated in various neurophysiological processes, including learning and memory, neuroprotection, neurogenesis, and inflammatory effects. In this review, we will summarize the effects of ghrelin on epilepsy. It may provide a comprehensive picture of the role of ghrelin in epilepsy...

PURPOSE: The anticonvulsant pregabalin is increasingly prescribed for pain, seizures, and psychiatric disorders. Although evidence suggests pregabalin can cause edema and heart failure, its cardiac safety profile in clinical practice is unknown. We sought to examine the risk of heart failure among older patients receiving pregabalin compared to those receiving gabapentin. METHODS: We conducted a population-based cohort study of Ontarians aged 66 and older with a history of seizure who received pregabalin or gabapentin between April 2013 and March 2014...

High-dose benzodiazepine (BZD) dependence represents an emerging and under-reported addiction phenomenon and is associated with reduced quality of life. To date there are no guidelines for the treatment of high-dose BZD withdrawal. Low-dose slow flumazenil infusion was reported to be effective for high-dose BZD detoxification, but there is concern about the risk of convulsions during this treatment. We evaluated the occurrence of seizures in 450 consecutive high-dose BZD dependence patients admitted to our unit from April 2012 to April 2016 for detoxification with low-dose slow subcutaneous infusion of flumazenil associated with routine anticonvulsant prophylaxis...

Hashimoto's encephalopathy (HE) is a rare autoimmune disorder with neurological and neuropsychiatric manifestations and elevated titres of anti-thyroid antibodies. Here we are reporting a case of HE in a 19-year-old girl who presented with seizure-like episodes, confusion, and behavioural disturbances with catatonic symptoms such as posturing, echopraxia, echolalia, and ambivalence. Patient did not respond to antipsychotics and anticonvulsants. On further investigation, patient was found to have high serum anti-TPO antibodies of about 1261 U/mL with euthyroid status, which supported a suspicion of HE...

REVIEW
Angelika Sysak, Bożena Obmińska-Mrukowicz
Due to its relatively easy synthesis, isoxazole ring has been as an object of interest for chemists and pharmacologists from research groups all over the world. Its chemical modifications include both connection of isoxazole with other aromatic, heteroaromatic or non aromatic rings and substitution with different alkyl groups. Thanks to their usually low cytotoxicity, isoxazole derivatives are still popular scaffolds for the development of new agents with variable biological activities, such as antimicrobial, antiviral, anticancer, anti-inflammatory, immunomodulatory, anticonvulsant or anti-diabetic properties...

PURPOSE: Prolonged seizures can cause severe harm and even death. For seizures lasting longer than 5min, an administration of rescue medication is therefore recommended. Caregivers such as preschool teachers should be able to administer correctly anticonvulsive rescue medication to children. METHODS: A training concept for preschool teachers on seizure management focussing on practical skills was developed. To assess the success of the training, a structured interview on attitudes relating to rescue medication administration was conducted...

Super refractory status epilepticus (SRSE) is a life-threatening condition in which seizures do not respond to third-line anticonvulsant drug therapy. SRSE is associated with high mortality. How often SRSE occurs, what are the risk factors leading to this condition, and what is the effect on clinical outcome of failure to control seizures are poorly defined. Several studies have evaluated magnetic resonance imaging (MRI) findings in status epilepticus (SE), confirming that SE may directly cause selective neuronal necrosis due to excitotoxic mechanisms, as described in clinical case reports and experimental models...

Benzodiazepines (BZDs), which bind with high affinity to gamma-aminobutyric acid type A receptors (GABAA-Rs) and potentiate the effects of GABA, are widely prescribed for anxiety, insomnia, epileptic discharge, and as anticonvulsants. The long-term use of BZDs is limited due to adverse effects such as tolerance, dependence, withdrawal effects, and impairments in cognition and learning. Additionally, clinical reports have shown that chronic BZD treatment increases the risk of Alzheimer's disease. Unusual GABAA-R subunit expression and GABAA-R phosphorylation are induced by chronic BZD use...

BACKGROUND: Neuropathic pain (NP) (including painful diabetic neuropathy, postherpetic neuralgia, etc) affects approximately 7% to 8% of the population and is associated with a devastating symptom burden as well as a profound economic impact for patients, their families, and the health care system. Current therapies have limited efficacy and dose-limiting adverse effects (AEs). Rational combination therapy with carefully selected NP drugs has shown potential for measurable improvements in pain relief, quality of life, and health care use...

Homocysteine and taurine are non-proteinogenic sulfur-containing amino acids with numerous important physiological roles. Homocysteine and taurine are considered to be neurotransmitters and neuromodulators, the first showing clear hyperexcitability role, while the second is known by its inhibitory and neuroprotective properties. In this article we addressed the role of homocysteine and its related metabolite homocysteine thiolactone in the development of seizures, focusing on its experimental models in vivo, potential mechanisms of proepileptogenic activity via interactions with glutamatergic neurotransmission, sodium pump activity, oxidative stress, cholinergic system and NO-mediated neuronal signaling, as well as the pharmacological and non-pharmacological approaches to modulate its proconvulsive activity...

BACKGROUND: Neonatal seizures are the most common clinical manifestation of central nervous system (CNS) dysfunction and are associated with various neurological sequelae. There are currently no evidence-based guidelines for the management of neonatal seizures and currently used drugs such as phenobarbital, and phenytoin have limited efficacy and potential toxicities. Newer second line anticonvulsant, levetiracetam, has been used in refractory neonatal seizures despite limited data and off-label use...

OBJECTIVES: An evidence base for the treatment of mania and bipolar depression with psychotic symptoms is lacking. Nevertheless, clinicians may have a preference for treating episodes of bipolar disorder with or without psychotic symptoms in different ways, which is likely to reflect notions of differential efficacy of treatments between these subtypes. This study aimed to investigate whether the psychopharmacological treatment of psychotic and non-psychotic episodes of mania and bipolar depression, respectively, differs in clinical practice...

γ-Ethyl-γ-phenyl-butyrolactone (EFBL) is a structural combination of the anticonvulsant γ-hydroxy-γ-ethyl-γ-phenylbutyramide (HEPB) and the hypnotic γ-butyrolactone (GBL), which inherits both properties. To clarify its mechanism of action, the effects of EFBL, GBL and HEPB on dopamine (DA) and noradrenaline (NA) brain levels were investigated. Influences of chlorpromazine, phenelzine and aminooxyacetic acid were also studied. EFBL increased DA in a dose-dependent manner, remaining enhanced by 80 % over a period of 24 h and augmented NA by 54 % one hour after treatment...
