GC-MS uncovers unique metabolic markers of drug-resistant epilepsy in capillary but not venous dried blood spots.

This study compared the effectiveness of capillary dried blood spots (DBS) versus venous DBS in detecting metabolic changes related to drug-resistant epilepsy (DRE). DBS samples were collected from 142 epilepsy patients (58 drug-resistant, 84 drug-responsive) via venipuncture or fingerstick capillary sampling. Metabolomic analysis using gas chromatography-mass spectrometry compared DBS metabolite profiles between the two groups.

Efficacy, safety, and tolerability of adjunctive brivaracetam in adult Asian patients with uncontrolled focal-onset seizures: A phase III randomized, double-blind, placebo-controlled trial.

Objective: Evaluate efficacy, safety, and tolerability of adjunctive brivaracetam (BRV) in adult Asian patients with focal-onset seizures (FOS).

Methods: Phase III, randomized, double-blind, placebo-controlled study (EP0083; NCT03083665) evaluating BRV 50 mg/day and 200 mg/day in patients (≥16-80 years) with FOS with/without secondary generalization (focal to bilateral tonic-clonic seizures) despite current treatment with 1 or 2 concomitant antiseizure medications. Following an 8-week baseline, patients were randomized 1:1:1 to placebo, BRV 50 mg/day, or BRV 200 mg/day, and entered a 12-week treatment period.

Which terms should be used to describe medications used in the treatment of seizure disorders? An ILAE position paper.

A variety of terms, such as "antiepileptic," "anticonvulsant," and "antiseizure" have been historically applied to medications for the treatment of seizure disorders. Terminology is important because using terms that do not accurately reflect the action of specific treatments may result in a misunderstanding of their effects and inappropriate use. The present International League Against Epilepsy (ILAE) position paper used a Delphi approach to develop recommendations on English-language terminology applicable to pharmacological agents currently approved for treating seizure disorders.

Evaluation of the promotion criteria in an academic medical centre in Singapore.

Introduction: Academic medical centres (AMCs) have the tripartite mission of performing research to advance healthcare delivery, educating future clinicians and providing healthcare services. This study investigates the criteria associated with being promoted in a Singaporean AMC.

Methods: Using a dataset of 255 candidates for promotion at the studied AMC, we employ logistic regression to determine if these factors are associated with the likelihood of promotion.

Calculator for predicting the probability of faculty promotion in an academic medical centre.

Objective: The academic medical centre (AMC), with over 2200 faculty members, annually manages approximately 300 appointments and promotions. Considering these large numbers, we explored whether machine learning could predict the probability of obtaining promotional approvals.

Methods: We examined variables related to academic promotion using predictive analytical methods.

Critique of the 2017 epileptic seizure and epilepsy classifications.

This article critiques the International League Against Epilepsy (ILAE) 2015-2017 classifications of epilepsy, epileptic seizures, and status epilepticus. It points out the following shortcomings of the ILAE classifications: (1) they mix semiological terms with epileptogenic zone terminology; (2) simple and widely accepted terminology has been replaced by complex terminology containing less information; (3) seizure evolution cannot be described in any detail; (4) in the four-level epilepsy classification, level two (epilepsy category) overlaps almost 100% with diagnostic level one (seizure type); and (5) the design of different classifications with distinct frameworks for newborns, adults, and patients in status epilepticus is confusing. The authors stress the importance of validating the new ILAE classifications and feel that the decision of Epilepsia to accept only manuscripts that use the ILAE classifications is premature and regrettable.

Revisiting the public awareness, attitudes, and understanding towards epilepsy among Singapore residents.

A survey to assess the familiarity, attitudes, and knowledge about epilepsy was done using a questionnaire identical to the one used in 1999. Two hundred forty-six people participated in our survey in 2017 as compared with 214 in the 1999 survey. In terms of familiarity about epilepsy, 76% had heard or read about epilepsy, 55.

Fine margin between crossed sensory and contralateral sensory loss: A case report.

The well-known sensory deficit in lateral medullary syndrome (LMS) involves crossed ipsilateral trigeminal area and contralateral spinothalamic tract area. A 45 year old man was admitted for sudden onset slurring of speech, unsteadiness and sensory complaints. The diagnosis was right lateral medullary syndrome due to right Vertebral Artery occlusion.

Ictal and interictal EEG patterns in patients with nonconvulsive and subtle convulsive status epilepticus.

Background: Electroencephalography findings in nonconvulsive or subtle convulsive status epilepticus (NCSE and SCSE, respectively) can be heterogenous. We aimed to study the different patterns on EEG in our cohort of patients.

Objective: Our objective was to study ictal and interictal EEG patterns in patients with NCSE and SCSE.

Research priorities in epilepsy for the Asia-Oceanian region.

The Asia-Oceanian region is the most populous region in the world. Although there has been substantial economic development and improvement in health services in recent years, epilepsy remains generally an underrecognized and understudied condition. To help promote research in the region, the Commission on Asian and Oceanian Affairs (CAOA) of the International League Against Epilepsy (ILAE) appointed the Research Task Force (RTF) to facilitate the development of research priorities for the region.

Clinical validation and implications of dried blood spot sampling of carbamazepine, valproic acid and phenytoin in patients with epilepsy.

To facilitate therapeutic monitoring of antiepileptic drugs (AEDs) by healthcare professionals for patients with epilepsy (PWE), we applied a GC-MS assay to measure three AEDs: carbamazepine (CBZ), phenytoin (PHT) and valproic acid (VPA) levels concurrently in one dried blood spot (DBS), and validated the DBS-measured levels to their plasma levels. 169 PWE on either mono- or polytherapy of CBZ, PHT or/and VPA were included. One DBS, containing ∼15 µL of blood, was acquired for the simultaneous measurement of the drug levels using GC-MS.

Prevalence of drug resistant epilepsy in adults with epilepsy attending a neurology clinic of a tertiary referral hospital in Singapore.

Purpose: To determine the proportion of population of adult people with epilepsy (PWE) in Singapore, who suffer from drug resistant epilepsy (DRE).

Methods: All adult PWE who had attended the neurology specialist clinic of a tertiary referral hospital in Singapore were profiled for drug responses according to the definition for DRE as specified by the International League against Epilepsy (ILAE) 2010 consensus. This is a retrospective cohort study.

This study aims to determine the health-seeking behaviour of local PCPs and to identify the predictors of local PCPs attaining the recommended level of exercise.

Methods: This study was a cross-sectional questionnaire survey, which included questions on the demographic characteristics, practice profiles and health-seeking behaviour of PCPs.

Methotrexate induced leucoencephalopathy: A stroke mimic.

With increasing usage of thrombolysis in the treatment of acute ischemic strokes within 4.5- hour window, it is becoming more important to recognize stroke mimics. Though the incidence of stroke mimics being thrombolysed is less than 3%, it is essential to diagnose them so as to avoid wrong thrombolytic treatment which carries potential complications of bleeding.

Estimation and comparison of carbamazepine population pharmacokinetics using dried blood spot and plasma concentrations from people with epilepsy: the clinical implication.

To establish using dried blood spot (DBS) as a surrogate to plasma for therapeutic drug monitoring (TDM) of carbamazepine (CBZ), we compared the population pharmacokinetic (PPK) estimates from concurrent DBS and plasma levels. The dose-concentration relationship, estimated parameter and variability were determined. A total of 98 observations from 97 people with epilepsy (PWE) were included in this study.

Methotrexate-induced myelopathy mimicking subacute combined degeneration of the spinal cord.

Methotrexate (MTX), a folate antagonist, is widely used to treat hematological malignancies. Although it is known to cause myelopathy, little is known about the pathophysiology and natural history of this myelopathy. We describe a 42-year-old woman with acute lymphoblastic leukemia who was treated with chemotherapy consisting of intrathecal MTX who developed a progressive myelopathy.

Efficacy and safety of levetiracetam as adjunctive therapy in adult patients with uncontrolled partial epilepsy: the Asia SKATE II Study.

This study evaluated the safety and efficacy of levetiracetam as adjunctive therapy for partial seizures in everyday clinical practice in Asian populations. Patients aged > or =16 years (N=251) with inadequately controlled partial epilepsy were recruited from 29 centers across Asia. Levetiracetam was added to existing antiepileptic medication for 16 weeks at a starting dose of 500 or 1000 mg/day and titrated to a maximum of 3000 mg/day according to clinical response.

Application of the McDonald MRI criteria in multiple sclerosis.

Introduction: The aim of this study was to assess the sensitivity of McDonald's magnetic resonance imaging (MRI) criteria for the diagnosis of multiple sclerosis (MS) in a group of Asian patients diagnosed with clinically definite MS, based on lesion characterisation on MRI scans.

Materials And Methods: Forty-nine patients from 3 major neurological institutions were classified as having Asian- or Western-type MS based on clinical assessment. Each MRI scan was reviewed by 2 neuroradiologists for the presence and characteristics of brain and spinal lesions.

Persistent hand spasm: movement disorder or seizure?

Dystonia is a movement disorder characterized by involuntary, sustained or repetitive, patterned muscle contractions or spasms, frequently causing squeezing and twisting movements or abnormal postures. Dystonic posturing could be one of the accompanying features of epilepsy. We report an elderly lady with intractable focal seizure who presented with more than a year of persistent hand spasms.
