Turkish Journal of Medical Sciences

Background/aim: The aim herein was to investigate epileptiform discharges on electroencephalogram (EEG), their correlation with glutamic acid decarboxylase 65 autoantibody (GAD-ab) in newly diagnosed pediatric type 1 diabetes mellitus (T1DM) patients and interpret their medium-term utility in predicting epilepsy. Materials and methods: Children presenting with T1DM between July 2018 and December 2019 were included in this prospective longitudinal study. Patients with a history of head injury, chronic illness, neurological disorder, seizure, autism, or encephalopathy were excluded. EEGs were obtained within the first 7 days of diagnosis and later reviewed by a pediatric neurologist. All of the children were clinically followed-up …


Levetiracetam Ameliorates Epileptogenesis By Modulating The Adenosinergic Pathway In A Kindling Model Of Epilepsy In Mice, Muhammad Jamal, Muhammad Azam, Salman Ali Khan, Zaheer Ul-Haq, Shabana Usman Simjee Oct 2023

Levetiracetam Ameliorates Epileptogenesis By Modulating The Adenosinergic Pathway In A Kindling Model Of Epilepsy In Mice, Muhammad Jamal, Muhammad Azam, Salman Ali Khan, Zaheer Ul-Haq, Shabana Usman Simjee

Turkish Journal of Medical Sciences

Background: Levetiracetam (LEV) has been found to have an antihyperalgesic effect via acting on the adenosine system. However, the effects of LEV on the modulation of the adenosine system in the brain have not been elucidated in the prevention of seizures and epilepsy. The present study aimed to explore the possible LEV mechanisms of action in the adenosine signaling systems in an animal model of epilepsy. Methodology: A docking study was initially performed to determine the possible interaction of LEV with adenosine A1 receptors (A1Rs) and equilibrative nucleoside transporters-1 (ENT1). The experimental study was divided into an acute seizure test …

Tuberous Sclerosis: A Review Of The Past, Present, And Future, Sanem Pinar Uysal, Mustafa Şahi̇n Jan 2020

Tuberous Sclerosis: A Review Of The Past, Present, And Future, Sanem Pinar Uysal, Mustafa Şahi̇n

Turkish Journal of Medical Sciences

Tuberous sclerosis complex (TSC) is an autosomal dominant, multisystem disorder that is characterized by cellular and tissue dysplasia in several organs. With the advent of genetic and molecular techniques, mutations in the TSC1 or TSC2 genes were discovered to be responsible for mTOR overactivation, which is the underlying mechanism of pathogenesis. TSC is a highly heterogenous clinical entity with variable presentations and severity of disease. The brain, heart, skin, eyes, kidneys, and lungs are commonly involved in this syndrome, with neurologic symptoms comprising a significant source of morbidity and mortality. In 2012, the diagnostic criteria for TSC were revised by …

Optimum Recording Time Of Routine Electroencephalogram For Adults With Epilepsy*, Kemal Tutkavul, Yilmaz Çeti̇nkaya

Turkish Journal of Medical Sciences

Background/aim: This study aimed to reveal the optimum recording time of routine electroencephalogram (EEG) for adults with epilepsy.Materials and methods: In this clinical observational study we investigated features of paroxysms that emerged in EEGs recorded for 45 min in adults with epilepsy.Results: Paroxysms were detected in 38.14% of 97 patients. The probability of occurrence of paroxysm during the first 10 min was found to be statistically significantly low in comparison to the first 30 and 45 min (respectively P = 0.004, P = 0.0001). This probability was found to increase insignificantly when comparing the first 20 min with the first …

Turkish Journal of Medical Sciences

Background/aim: Epileptic seizure leads to sudden unexpected death in epilepsy (SUDEP) among affected patients. The causes of SUDEP are still unclear. The aim of this study was to research the effect of epilepsy on myocardial injury and arrhythmias during experimentally induced acute myocardial ischemia. Materials and methods: Wistar albino rats were divided into four groups: sham, pentylentetrazole (PTZ) + sham, ischemia, and PTZ + ischemia groups. PTZ (65 mg/kg, ip) was given 2 h before ischemia. Seizure scoring was conducted by evaluating the PTZ-induced behavioral changes in the rats. The left main coronary artery was ligated in anesthetized rats for …

Turkish Journal of Medical Sciences

To comparatively investigate the effects of linoleic acid on convulsive and nonconvulsive epileptic seizures. Materials and methods: Rats were divided into 3 groups: convulsive epileptic rats receiving only pentylentetrazole (PTZ) injections (group 1), convulsive epileptic rats receiving PTZ and linoleic acid (group 2), and Wistar Albino Glaxo rats from Rijswijk with genetic absence epilepsy receiving linoleic acid (group 3). The duration and severity of convulsive activity were determined in groups in which convulsive seizures were induced by PTZ. In group 3, intravenous linoleic acid was administered after 1-h baseline electroencephalography (EEG) recordings. The EEG recordings were analyzed. Results: When groups …

Pregnancy Associated Plasma Protein-A And Epilepsy, Abdurrahman Coşkun, Burcu Özdemi̇rli̇, Ramazan Memi̇şoğullari Jan 2007

Pregnancy Associated Plasma Protein-A And Epilepsy, Abdurrahman Coşkun, Burcu Özdemi̇rli̇, Ramazan Memi̇şoğullari

Turkish Journal of Medical Sciences

In this study, we aimed to investigate the role of pregnancy-associated plasma protein-A (PAPP-A) as insulin-like growth factor binding protein-4 (IGFBP-4) protease in epilepsy patients. We studied 16 epilepsy patients and 10 healthy controls. Serum PAPP-A levels of epilepsy patients (6.8 ± 3.2 mU/L) were higher than of the control group (5.1 ± 1.9 mU/L), but the difference was not statistically significant (P > 0.05). We concluded that PAPP-A may increase the bioavailability of insulin-like growth factors (IGFs) due to decreased neurogenesis and synthesis of IGFs in chronically epilepsy patients.
