Surgical Outcomes Related to Invasive EEG Monitoring with Subdural Grids or Depth Electrodes In Adults: A Systematic Review and Meta-Analysis

Publication date: Available online 18 June 2019Source: SeizureAuthor(s): Marton Toth, Kata Szilvia Papp, Noemi Gede, Kornelia Farkas, Sandor Kovacs, Jean Isnard, Koichi Hagiwara, Csilla Gyimesi, Diana Kuperczko, Tamas Doczi, Jozsef JanszkyAbstractPurposeResective epilepsy surgery based on an invasive EEG-monitors performed with subdural grids (SDG) or depth electrodes (stereo-electroencephalography, SEEG) is considered to be the best option towards achieving seizure-free state in drug-resistant epilepsy. The authors present a meta-analysis, due to the lack of such a study focusing on surgical outcomes originating from SDG- or SEEG-monitors.MethodEnglish-language studies published until May 2018, highlighting surgical outcomes were reviewed. Outcome measures including total number of SDG- or SEEG-monitors and resective surgeries; consecutively followed surgical cases; surgical outcomes classified by Engel in overall, temporal/extratemporal and lesional/nonlesional subgroups were analyzed.Results19 articles containing 1025 SDG-interventions and 16 publications comprising 974 SEEG-monitors were researched. The rate of resective surgery deriving from SDG-monitoring hovered at 88.8% (95%CI:83.3-92.6%) (I2 = 77.0%;p

A known cause of seizure-induced respiratory arrest is the deficiency in serotonergic neurotransmission. Tryptophan hydroxylase-2 (TPH2) is the rate-limiting enzyme of central serotonin (5-hydroxytryptamine) synthesis which converts l-tryptophan to 5-hydroxytryptophan. A recent study revealed a reduction in TPH2 protein expression in the brainstems of DBA/1 mice that developed recurrent seizure-induced respiratory arrest, whereas the activity of this protein was unexplored. Thus this study aims to investigate the association between intrinsic 5-hydroxytryptamine synthesis in the brainstem and the susceptibility for sudden ...

Conclusions: Our study demonstrates that a combination of bioanalytical cross-validation and clinical evaluation is an effective way to describe the applicability of DBS as an alternative to plasma, taking into account how therapeutic drug monitoring is used in specific patient groups. For LTG, converted CBZ and VPA, DBS is a feasible alternative for self-sampling at home. DBS for LEV can only be recommended for nonadherence queries due to the high variability of the plasma/DBS concentration ratios.

ABSTRACT Objective To analyze the risk factors and prognosis related to early post-traumatic epilepsy (EPTE). Methods One hundred and eighty-six patients with traumatic brain injury were enrolled. Their full clinical data were collected. Single factor analysis and logistic regression analysis of risk factors related to EPTE were performed. The prognosis of patients was determined. Results Single factor analysis showed that there were significant differences of age (p = 0.011), epilepsy history (p

This study showed that vortioxetine reduces the number of acutely-induced epileptic discharges. Vortioxetine may be an important alternative for epileptic patients with major depressive disorder-related cognitive dysfunction.RESUMO A vortioxetina é um agente antidepressivo multimodal que modula os receptores 5HT e inibe o transportador de serotonina. Está indicada, principalmente nos casos de transtorno depressivo maior (TDM), relacionado à disfunção cognitiva. Existem muitos estudos que investigam os efeitos dos antidepressivos no limi ar convulsivo e na atividade epiléptica de cu...

Glucose transporter-1 (GLUT1)/SLC2A1 is expressed at the highest levels in brain capillaries, astroglia, and erythrocytes. GLUT1-deficiency syndrome is a neurological disorder resulting primarily from aberrant glucose transport into the brain. Clinically, it is classified as GLUT1-deficiency syndrome with epilepsy and without epilepsy. The phenotypic spectrum of GLUT1- deficiency syndrome expanded over last two decades, encompassing a varying combination of epilepsies (absence, atypical absence, myoclonic, myoclonic-astatic, refractory generalized epilepsy, intractable infantile epilepsy etc.), movement disorders (paroxysm...

Authors: Nishitani A, Yoshihara T, Tanaka M, Kuwamura M, Asano M, Tsubota Y, Kuramoto T Abstract Hyperpolarization-activated cyclic nucleotide-gated 1 (HCN1) channels contribute to spontaneous rhythmic activity in different tissues, including the heart and brain. Deficiency in HCN1 function is associated with sick sinus syndrome in mice and epilepsy in humans. We recently developed Hcn1-deficient rats and found that they exhibit absence epilepsy. While rearing Hcn1-deficient rats, we noticed loose muscle tension and abnormal gait. We therefore evaluated the muscle strength and motor functions of Hcn1-deficient rats...
