Ménière disease is a disorder of the inner ear, characterized by rotational vertigo, hearing loss, tinnitus, and vegetative symptoms. The aim of the present research is to examine the effectiveness of betahistine and piracetam in the reduction of vertigo attacks in Ménière disease. To verify our hypothesis, 105 (31 male and 74 females, mean age [standard deviation], 57.4 [11.05]) adult patients with definite Ménière disease were enrolled in this investigation. Beside the analysis of the hospital records, the subjective complaints of the patients and the completed vertigo diaries were taken into consideration too. The statistical analysis was completed using the IBM SPSS version 24 software. Retrospective analysis, including a 12 years period was conducted. Based on our results, betahistine was successful in the reduction of attacks. Statistically significant decrease was achieved in frequency of dizziness (P = .000331) and vertigo (P < .00001) and in the duration of them (P = .000098), although in the mean power of them was not (P = .0887). The mean dose in the symptomatic treatment was determined as 87.5 ± 27.2 mg per day; however, there was no connection detected between the dose of the agent and the effectiveness of the symptomatic control. By using dual therapy (betahistine and piracetam), vertigo episodes appeared significantly less often (P = .027, Odds ratio: 4.9, 95% confidence interval: 1.2-20.2). Finally, it can be concluded that betahistine is effective in Ménière disease, but the daily dose of it should be set up for every patient individually. The advantage of the dual therapy was also confirmed.

OBJECTIVE: The objective of the study was to perform a systematic review and meta-analysis to evaluate the efficacy and safety of levetiracetam (LEV) or phenytoin (PHT) as second-line treatment for status epilepticus (SE). METHODS: PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Latin American and Caribbean Health Sciences Literature (LILACS), Scopus, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, and Google Scholar were assessed for prospective randomized trials comparing LEV with PHT as second-line treatment of SE published from inception until December 18th, 2019. The primary outcome was seizure cessation. Data were analyzed using a random-effects model. Quality analysis was performed using version 2 of the Cochrane risk-of-bias tool (RoB 2). The study protocol was registered on PROSPERO (CRD42020136417). RESULTS: Nine studies with a total of 1732 patients were included. Overall, seizure cessation occurred in 657 of 887 (74%) of patients in the LEV group and 600 of 845 (71%) in the PHT group. Treatment success did not differ significantly between groups, and the relative risk (RR) was 1.05 (95% confidence interval (CI): 0.98-1.12; I2 = 53%). Six of the studies were at low risk of bias, one study had some risk, and two studies had high risk. CONCLUSIONS: The use of LEV or PHT as second-line agents after benzodiazepine (BZD) for the treatment of SE was not associated with a difference in seizure cessation. Because there are minimal differences in efficacy at this time, clinicians should consider alternative factors when deciding on an antiepileptic drug (AED).

R-phenylpiracetam (R-PhP, (4R)-2-(4-phenyl-2-oxopyrrolidin-1-yl)acetamide) is an optical isomer of phenotropil, a clinically-used nootropic drug that improves physical condition and cognition. Recently, R-PhP was shown to bind to the dopamine transporter (DAT). Since growing evidence suggests that dysfunction of the dopaminergic system is associated with persistent neuroinflammation, the aim of this study was to determine whether R-PhP, an inhibitor of DAT, has neuroprotective and anti-inflammatory effects in male mice. The pharmacokinetic profiles of R-PhP in mouse plasma and its bioavailability in brain tissue were assessed. To study possible molecular mechanisms involved in the anti-inflammatory activity of R-PhP, target profiling was performed using radioligand binding and enzymatic activity assays. To clarify the neuroprotective and anti-inflammatory effects of R-PhP, we used a lipopolysaccharide (LPS)-induced endotoxaemia model characterized by reduced body temperature and overexpression of inflammatory genes in the brain. In addition, the antinociceptive and anti-inflammatory effects of R-PhP were tested using carrageenan-induced paw oedema and formalin-induced paw-licking tests. R-PhP (50 mg/kg) reached the brain tissue 15 min after intraperitoneal (ip) and peroral (po) injections. The maximal concentration of R-PhP in the brain tissues was 28 µg/g and 18 µg/g tissue after ip and po administration, respectively. In radioligand binding assays, DAT was the only significant molecular target found for R-PhP. A single ip injection of R-PhP significantly attenuated the LPS-induced body temperature reduction and the overexpression of inflammatory genes, such as tumour necrosis factor-α (TNF-α), interleukin 1 beta (IL-1ß) and inducible nitric oxide synthase (iNOS). Seven-day po pretreatment with R-PhP dose-dependently reduced paw oedema and the antinociceptive response, as shown by the carrageenan-induced paw oedema test. In addition, R-PhP decreased the nociceptive response during the inflammatory phase in the formalin-induced paw-licking test. Our study showed that R-PhP possesses neuroprotective and anti-inflammatory effects, demonstrating the potential of DAT inhibitors as effective therapeutics.

Pharmacotherapy and cognitive behavioral therapy, both fail to treat post-traumatic stress disorder (PTSD) in a considerable number of populations. The persistence of traumatic memories and deficit in extinction contributes to the failure of exposure therapy in PTSD. With the objective to enhance the outcomes of exposure therapy by targeting the extinction window using pharmacological agents in PTSD, the present study was aimed to explore the effect of piracetam, risperidone and their combinations in experimentally-induced PTSD-like phenotype in rats. Male SD rats were exposed to single prolonged stress model (SPS) for induction of PTSD-like behavioral changes. Piracetam, risperidone and their combination were used as therapeutic interventions while sertraline was used as a standard treatment for 14 days along with extinction training. Induction of PTSD-like behaviors were assessed in behavioral tests such as fear conditioning, elevated plus maze, social interaction test, and the marble burying test. Neurotransmitters (dopamine and serotonin and their metabolites), BDNF, proinflammatory cytokines (TNF-α, IL-6), caspase-3, and markers for oxidative stress were assessed in the hippocampus and cortex while corticosterone and nitrite levels were estimated in plasma. Our result indicated that the SPS paradigm efficiently induced PTSD-like phenotype in rats. Risperidone and piracetam were found to be effective alone, while their high dose combination, produced potentiating effect in reversing the extinction deficit, behavioral alterations, altered cortical and hippocampal BDNF, IL-6, TNF-α, caspase-3, oxidative stress markers, and neurotransmitter levels. Plasma corticosterone and nitrite levels were also found to be reversed in the combination treated groups. Our preliminary study suggests that piracetam, risperidone and their combination restored the physiological cascades in cortex and hippocampus along with successful suppression of fear memory and a symptom cluster of PTSD-like phenotype in rats. Hence they could be used as an effective adjunct to enhance the outcome of exposure therapy for the management of PTSD.

BACKGROUND: No guidelines exist concerning the maintenance antiepileptic drug to use after neonatal seizures. Practices vary from one hospital to another. The aim of this study was to investigate etiologies and to report on the use of maintenance antiepileptic therapy in our population of full-term neonates presenting neonatal seizures. METHODS: From January 2004 to October 2014, we retrospectively collected data from all full-term neonates with neonatal seizures admitted to the Children's Hospital of Toulouse, France. RESULTS: Two hundred and forty-three neonates were included (59% males, 48% electroencephalographic confirmation). The frequencies of etiologies of neonatal seizures were: hypoxic-ischemic encephalopathy (HIE) (n = 91; 37%), ischemic infarction (n = 36; 15%), intracranial hemorrhage (n = 29; 12%), intracranial infection (n = 19; 8%), metabolic or electrolyte disorders (n = 9; 3%), inborn errors of metabolism (n = 5; 2%), congenital malformations of the central nervous system (n = 11; 5%), epileptic syndromes (n = 27; 12%) and unknown (n = 16; 7%). A maintenance therapy was prescribed in 180 (72%) newborns: valproic acid (n = 123), carbamazepine (n = 28), levetiracetam (n = 17), vigabatrin (n = 2), and phenobarbital (n = 4). In our cohort, the choice of antiepileptic drug depended mainly on etiology. The average duration of treatment was six months. CONCLUSIONS: In our cohort, valproic acid was the most frequently prescribed maintenance antiepileptic therapy. However, the arrival on the market of new antiepileptic drugs and a better understanding of the physiopathology of genetic encephalopathies is changing our practice. TRIAL REGISTRATION: Retrospectively registered. Patient data were reported to the "Commission Nationale Informatique et Libertés" under the number 2106953 .

Vascular dementia is considered a vascular cognitive impairment disease caused by neuronal degeneration in the brain. Several studies have supported the hypothesis that oxidative stress and endothelial dysfunction are the main pathogenic factors in vascular dementia. This current study aims to determine the possible neuroprotective effects of zafirlukast, piracetam and the combination of piracetam and zafirlukast on L-methionine-induced vascular dementia in rats. Male Wistar albino rats were divided into five groups. Group I was the normal control, and group II received L-methionine (1700 mg/kg, P.O.) for 32 days. The remaining groups received zafirlukast (20 mg/kg, P.O.), piracetam (600 mg/kg, P.O.) or their combination (zafirlukast 20 mg/kg + piracetam 600 mg/kg, P.O.) for 32 days after L-methionine administration. Afterwards, the cognitive and memory performances of the rats were investigated using the novel object recognition (NOR) test; rats were then sacrificed for histopathological and biochemical analyses. L-methionine-induced vascular dementia altered rats' behaviours and the brain contents of different neurotransmitters and acetylcholinesterase activity while increasing levels of oxidative stress and causing notable histopathological alterations in brain tissues. The treatment of vascular dementia with zafirlukast and the combination improved neurochemical, behavioural and histological alterations to a comparable level to those of piracetam. Thus, zafirlukast, piracetam and the combination of both drugs can be considered as potential therapeutic strategies for the treatment of vascular dementia induced by L-methionine. To the best of our knowledge, this study is the first to explore the neuroprotective effects of zafirlukast and piracetam on L-methionine-induced vascular dementia.

AIMS: The study aim was to test the efficacy of a novel created hybrid nanosystem compared to other nanosystems in treatment of scopolamine induced memory impairment. MAIN METHODS: The fabrication and characterization of nanoformulations (microemulsion, liposomes, ethosomes, transfersomes and transethosomes) coencapsulating two cognitive enhancers; piracetam and vinpocetine delivered intranasally, in addition to a novel nanocomposite microemulsion/vesicular nanoformulation was described. KEY FINDINGS: Formulations delivered the drugs across sheep nasal mucosa, with cumulative percentage reaching 29.99% for vinpocetine and 57.78% for piracetam. While the solution form of the drugs was totally ineffective, the selected transethosomal, microemulsion and nanocomposite formulations reversed the scopolamine induced effect on the step through latency of passive avoidance test and the spontaneous alternation behavior in Y maze test, further confirmed by histopathlogical examination. All three nanoformulations significantly decreased the acetylcholinesterase activity and the extent of lipid peroxidation by 32-42%. The nanocomposite formulation was superior to the microemulsion and transethosomal formulations in its anti-inflammatory and antiapoptotic effects, delineated by higher extent of inhibition of COX-2 and caspase 3 expression respectively. SIGNIFICANCE: Results support the hypothesis that the novel microemulsion/vesicular nanocomposite system is a promising neuroprotective modality for intranasal brain targeting which is worthy of exploitation in other brain diseases.

A 20-year-old female was hospitalized due to generalized seizure two weeks after an infection. She reported disorientation, neck stiffness and weakness in her legs. MRI FLAIR images and T2WI on her first visit to our hospital showed hyperintense lesions in the bilateral cingulate gyrus and the medial region of the superior frontal gyrus. Gadolinium (Gd)-enhanced T1WI showed enhancement in the upper part of the corpus callosum. Examination of her cerebrospinal fluid (CSF) revealed mildly elevated leucocytes. After the administration of high-dose intravenous methylprednisolone, her symptoms partially improved. However, MRI T2WI at 16 days after admission showed a lesion with a peripheral hypointense rim in the left side of the cingulate gyrus, which had ring enhancement on contrast CT. FLAIR images at 28 days after admission showed the hyperintense lesion spreading in the subcallosal area and the brainstem, and coronal short inversion time inversion recovery (STIR) images demonstrated bilateral optic neuritis. She was treated with steroid pulse therapy and plasma exchange. Thereafter her symptoms improved. The patient's CSF at 27 days after admission tested positive for anti-myelin oligodendrocyte glycoprotein (anti-MOG) antibodies and anti-N-methyl-D-aspartate (anti-NMDA) receptor antibodies. Encephalitis with optic neuritis in a patient with both anti-MOG and anti-NMDA receptor antibodies is very rare. Coexistence of multiple antibodies in the same patient may contribute to the diversity of autoimmune diseases associated with anti-MOG antibodies or anti-NMDA receptor antibodies.

OBJECTIVE: The purpose of this study was to determine the effect of lamotrigine (LTG) and levetiracetam (LEV) as mono- and polytherapy on biochemical markers of bone turnover and bone mineral density in Egyptian adult patients with epilepsy. METHODS: Forty-eight patients were divided into four groups: two received monotherapy of either LTG or LEV, and the other two groups received polytherapy comprising (valproate [VPA] + LTG or VPA + LEV). Thirty matched healthy participants were included in the study. Participants completed a nutritional and physical activity questionnaire. Biochemical markers of bone and mineral metabolism and bone mineral density of the lumbar spine were measured at baseline and at six months. RESULTS: In the LEV monotherapy group, the bone formation markers showed a significant decrease in serum alkaline phosphatase and serum osteocalcin levels while the bone resorption marker showed a significant increase in urinary deoxypyridinoline levels. After six months of treatment, bone mineral density showed a significant decrease in all treated groups, while among monotherapy groups, this significant decrease was more prevalent in the LEV monotherapy group compared with the LTG monotherapy group. Furthermore, there was significant negative correlation between urinary deoxypyridinoline levels and bone mineral density in the LEV monotherapy group. CONCLUSION: Using new generation antiepileptics, LEV monotherapies and polytherapy showed harmful effects on bone but LTG did not.

Unverricht-Lundborg disease (ULD) is a form of progressive myoclonus epilepsy characterized by stimulation-induced myoclonus and seizures. This disease is an autosomal recessive disorder, and the gene CSTB, which encodes cystatin B, a cysteine protease inhibitor, is the only gene known to be associated with ULD. Although the prevalence of ULD is higher in the Baltic region of Europe and the Mediterranean, sporadic cases have occasionally been diagnosed worldwide. The patient described in the current report showed only abnormally enlarged restriction fragments of 62 dodecamer repeats, confirming ULD, that were transmitted from both her father and mother who carried the abnormally enlarged restriction fragment as heterozygotes with normal-sized fragments. We report the first case of a genetically confirmed patient with ULD in Korea.

Chronic psychological stress is an important public health issue which generates behavioral changes, anxiety, immunosuppression and oxidative damage. Piracetam is a cognitive enhancer, at cellular level it protects from oxidative stress. The aim of this study was to evaluate the effect of psychological stress and of piracetam on circulating mononuclear cells by analyzing the biochemical spectrome using Synchrotron Radiation Fourier Transform Infrared Microspectroscopy (SR-µFTIR). Rats were exposed for five days to a stressor (cat odor) under oral administration of piracetam (600 mg/kg). SR-µFTIR analysis showed a decrease in bands associated to the lipids region (2852 cm-1, 2923 cm-1 and 2962 cm-1) and an increase absorption of the amide I band (1654 cm-1) under stress conditions. The principal component analysis showed increase oxidation of lipids (decrease of 3010 cm-1, 2923 cm-1 and 2852 cm-1 bands) as well as proteins denaturation (increase of 1610 cm-1 and 1690 cm-1 bands) under stress. Piracetam provided protection to polyunsaturated lipids (p ≤ 0.001) and lipids/proteins ratio (p ≤ 0.001). Behaviorally, this drug diminished fear and anxiety in stressed animals by the plus maze test (p ≤ 0.002). However, this drug induced oxidative stress in mononuclear cells from unstressed animals and altered their behavior.

Aphasia is a language disorder characterised by loss of ability to produce or comprehend written or spoken language. In majority of the cases, it is due to stroke. Aphasia may also present as an ictal or postictal state of temporal or frontal lobe seizures. Nevertheless, its isolated occurrence in individuals without a clear-cut history of seizures raises diagnostic difficulties with important therapeutic implications.A case of epileptic aphasia is reported in which the diagnosis was confirmed by electroencephalogram with a dramatic therapeutic response to an antiepileptic drug.

RESUMO O objetivo deste estudo foi determinar o efeito da lamotrigina (LTG) e levetiracetam (LEV) como mono e politerapia em marcadores bioquímicos de remodelação óssea e densidade mineral óssea em pacientes adultos egípcios com epilepsia. Métodos Quarenta e oito pacientes foram divididos em quatro grupos: dois grupos receberam monoterapia de LTG ou LEV e os outros dois grupos receberam politerapia (valproato [VPA] + LTG ou VPA + LEV). Trinta participantes saudáveis controle foram incluídos no estudo. Os participantes preencheram um questionário nutricional e de atividade física. Marcadores bioquímicos do metabolismo ósseo e mineral e densidade mineral óssea da coluna lombar foram medidos no início e aos seis meses. Resultados No grupo de monoterapia LEV, os marcadores de formação óssea mostraram uma diminuição significativa nos níveis séricos de fosfatase alcalina e osteocalcina sérica, enquanto o marcador de reabsorção óssea mostrou um aumento significativo nos níveis de desoxipiridinolina urinária. Após seis meses de tratamento, a densidade mineral óssea mostrou uma diminuição significativa em todos os grupos tratados, enquanto entre os grupos de monoterapia, esta diminuição significativa foi mais prevalente no grupo de monoterapia LEV em comparação com o grupo de monoterapia LTG. Além disso, houve correlação negativa significativa entre os níveis de desoxipiridinolina urinária e densidade mineral óssea no grupo de monoterapia LEV. Conclusão Utilizando antiepilépticos de nova geração, as monoterapias LEV e a politerapia mostraram efeitos prejudiciais no osso, mas a LTG não.

BACKGROUND: Levetiracetam can be used for seizure control alone or in combination with other antiepileptic medications. A previous study achieved the minimum targeted serum drug concentration after rectal administration of levetiracetam in healthy dogs. The purpose of the present study was to determine the pharmacokinetics of rectal LEV in dogs presented for cluster seizures or status epilepticus and potentially in treatment with other anti-epileptic drugs. Furthermore, preliminary information on response to this treatment as add-on to the standard treatment protocol is reported. RESULTS: Eight client-owned dogs were enrolled. Plasma levetiracetam concentrations (measured at 0, 30, 60, 90, 120, 180, 240, 360, 720, and 1440 min after drug administration) reached the minimum target concentration (5 µg/ml) at 30 min in all but one patient. At T1 (30 min) the mean concentration was 28.2 ± 15.5 µg/ml. Plasma concentrations remained above the targeted minimum concentration in all patients until 240 min and in 7/8 until 360 min. Six out of eight patients experienced no seizures in the 24-h period after hospitalization and were classified as "responders". CONCLUSIONS: Minimum plasma levetiracetam concentration can be reached after rectal administration of 40 mg/kg in dogs affected by cluster seizures and status epilepticus and concurrently receiving other antiepileptic drugs. These preliminary results may encourage the evaluation of rectal levetiracetam as an additional treatment option for cluster seizures and status epilepticus in a larger number of dogs.

BACKGROUND: In previous study, we have found intermittent oral levetiracetam (LEV) can effectively prevent recurrence of febrile seizure (FS). This study aimed to analyze the effects of the preventive on the patients with frequent FS accompanied with epileptiform discharge. METHODS: Patients with frequent FS were assigned to undergo Electroencephalogram (EEG). At the onset of fever, the patients who presented epileptiform discharge were orally administered with LEV with a dose of 15-30 mg/kg per day twice daily for 1 week, thereafter, the dosage was gradually reduced until totally discontinued in the second week. The seizure frequency associated with febrile events and FS recurrence rate during a 48-week follow-up were analyzed. RESULTS: among the 19 patients presented epileptiform discharge on EEG, 31.58% (6 of 19) had complex FS, 68.42% (13 of 19) had simple FS. Up to 57.89% (11 of 19) had a family history of seizure disorder and 36.84% (7 of 19) had a family history of FS in first-degree relatives. 42.11% (8 of 19) happened the first FS episode at the age < 18 months. 36.84% (7/19) presented generalized spikes, 63.16% (12/19) showed focal spikes. During the 48-week follow-up period, the patients experienced 26 febrile episodes, none of them presented seizure recurrence. CONCLUSION: Intermittent oral LEV can prevent the seizure recurrence of FS accompanied with epileptiform discharge in 48-week. However, further randomized controlled trials should be conducted.

RATIONALE: The case report aims to discuss the clinical symptoms and treatment of encephalopathy caused by a novel syntaxin- binding protein 1 (STXBP1) genetic mutation. PATIENT CONCERNS: The patient, a girl, was born at 38+4 weeks of gestation. She had frequent spasm attacks accompanied by obvious psychomotor development retardation since the neonatal period. Genetic screening identified a novel STXBP1 genetic mutation. DIAGNOSES: Early-onset epileptic encephalopathy with STXBP1 mutation. INTERVENTIONS: We adjusted the antiepileptic strategy to oral levetiracetam and topiramate, and intravenous administration of adrenocorticotropic hormone(ACTH) for 2 weeks. Subsequently, prednisone was continued, and gradually reduced and withdrawn over 3 months. OUTCOMES: The treatment was effective with complete control of the epileptic seizures and improvements in the electroencephalogram readings. However, the effects on psychomotor ability were slow and limited. A literature review of STXBP1 mutation cases in which ACTH was administered showed that complete seizure control is observed in 60% of cases, 20% are partially affected, and the remaining 20% show no effect. LESSONS: ACTH and levetiracetam had good therapeutic effects in epilepsy control in this case of de novo STXBP1 mutation. ACTH is an effective drug for early-onset epileptic encephalopathy caused by STXBP1 mutation. However, controlling epilepsy using this therapy does not alter the psychomotor development retardation caused by the STXBP1 mutation.

INTRODUCTION: Noise exposure, the main cause of hearing loss in countries with lot of industries, may result both in temporary or permanent hearing loss. The goal of this study was to investigate the effects of parenteral papaverine and piracetam administration following an acoustic trauma on hearing function with histopathologic correlation. MATERIALS AND METHODS: Eighteen Wistar albino rats exposed to noise for 8 h in a free environment were included. We divided the study population into three groups, and performed daily intraperitoneal injections of papaverine, piracetam, and saline, respectively, throughout the study. We investigated the histopathologic effects of cellular apoptosis on inner hair cells (IHCs) and outer hair cells (OHCs) and compared the distortion product otoacoustic emissions (DPOAEs) thresholds among the groups. RESULTS AND DISCUSSION: On the 3rd and 7th days, DPOAE thresholds at 8 kHz were significantly higher both in papaverine and piracetam groups compared with the control group (P = 0.004 for 3rd day, P = 0.016 and P = 0.028 for 7th day, respectively). On the 14th day, piracetam group had significantly higher mean thresholds at 8 kHz (P = 0.029); however, papaverine group had similar mean thresholds compared to the control group (P = 0.200). On the 3rd and 7th days following acoustic trauma, both IHC and OHC loss were significantly lower in both papaverine and piracetam groups. On the 7th day, the mean amount of apoptotic IHCs and OHCs identified using Caspase-3 method were significantly lower in both groups, but the mean amount identified using terminal deoxynucleotidyl transferase dUTP nick end labeling method were similar in both groups compared to the control group. CONCLUSION: We demonstrated the effects of papaverine and piracetam on the recovery of cochlear damage due to acoustic trauma on experimental animals using histopathologic and electrophysiologic examinations.

INTRODUCTION: Progressive myoclonic epilepsy (PME) is rare epilepsy syndrome. Although EEG is a useful neurophysiological technique in the evaluation of epilepsy, few EEG abnormalities have been described in PME. So, how to use EEG hints to establish the suspected diagnosis of PME as soon as possible should be addressed. CASE PRESENT: We presented a case with refractory myoclonic seizures, and progressive neurological deterioration, diagnosed as PME and neuronal ceroid lipofuscinosis disease by gene testing. The patient manifested with a significant regression in her speech ability and motor balance. The mini-mental state examination showed poor scores of 15/30. The magnetic resonance imaging showed diffused atrophy. Her EEG showed slow background with continuous occipital small spikes and photosensitivity. The following genetic testing with mutation in CLN6 confirmed the diagnosis and excluded the occipital epilepsy. CONCLUSION: Our case showed rare manifestations and special EEG features of PME, which may be confused with occipital epilepsy or photosensitive epilepsy. Thus, if the continuous occipital spikes and photosensitivity were presented in a patient with refractory seizures and developmental regression, PME should be considered.

Over last fifty years, intravenous (iv) phenytoin (PHT) loading dose has been the treatment of choice for patients with benzodiazepine-resistant convulsive status epilepticus and several guidelines recommended this treatment regimen with simultaneous iv diazepam. Clinical studies have never shown a better efficacy of PHT over other antiepileptic drugs. In addition, iv PHT loading dose is a complex and time-consuming procedure which may expose patients to several risks, such as local cutaneous reactions (purple glove syndrome), severe hypotension and cardiac arrhythmias up to ventricular fibrillation and death, and increased risk of severe allergic reactions. A further disadvantage of PHT is that it is a strong enzymatic inducer and it may make ineffective several drugs that need to be used simultaneously with antiepileptic treatment. In patients with a benzodiazepine-resistant status epilepticus, we suggest iv administration of levetiracetam as soon as possible. If levetiracetam would be ineffective, a further antiepileptic drug among those currently available for iv use (valproate, lacosamide, or phenytoin) can be added before starting third line treatment.

Withdrawal of antiepileptic drugs (AEDs) is a standard procedure during presurgical epilepsy assessment. Rapid and, at times, even pre-hospital withdrawal of medication is performed in some centres to enhance the yield of recorded seizures during video-EEG monitoring. AED withdrawal, however, affects the propensity and speed of propagation of epileptic activity, may evoke more severe seizures, and may cause pitfalls in EEG interpretation. We report a case which had been recommended to undergo intracranial EEG recordings in order to clarify apparently discordant MRI findings and ictal EEG patterns when monitoring was performed following complete AED withdrawal. Re-evaluation to assess scalp EEG patterns at several drug levels during slow AED tapering showed a loss of localizing information with AED withdrawal due to contralateral and bitemporal spread of frontal epileptic activity. Our report demonstrates that in individual cases, rapid AED withdrawal during presurgical video-EEG monitoring can impair the validity of EEG recordings and lead to unnecessary risks and investigations during workup.
