Migralepsy; clinical and electroencephalography findings in children

Aim: Migralepsy is a clinical entity that occasionally represents a diagnostic problem. An apparent history and clinical manifestation of migraine may mask the epileptic attack accompanying migralepsy. The aim of this study is to present our experience with clinical and electroencephalography (EEG) findings and treatment of our patients diagnosed with childhood migralepsy disease.Methods: We documented six patients who were initially followed-up with a diagnosis of migraine, subsequently observed to have epileptic seizures, and then diagnosed with migralepsy.Result: Our patients became asymptomatic by giving good responses to antiepileptic therapy based on clinical and electroencephalography (EEG) findings.Conclusions: This case series shows that EEG recording can be useful in all stages of migraine for long-term, safe monitoring. Identifying patients with possible migralepsy will enable them to receive antiepileptic treatment

Use of salidroside in a lipopolysaccharide-induced periventricular leukomalacia model

Aim: Research into the different treatment methods based on the intrauterine lipopolysaccharide (LPS)-induced Periventricular leukomalacia (PVL) model, as one of the main causes of morbidity in preterm infants still continues to be relevant. The present study investigates the effect on PVL of salidroside obtained from Rhodiola Rosea (golden root, orpin rose), which is a plant with known for its medicinal qualities. Method: To develop an induced PVL model, a 500 microgram/kg dose of LPS (Escherichia coli, serotype 055:B5, Sigma) was applied to two pregnant rats intraperitoneally on day 18, day 19 and day 20 of gestation. One of the LP applied rats was given 25 mg/kg Salidroside (250 mg Rhodiola root extract capsules, which include 3 mg Salidroside) by oral gavage (LPS+Salidroside), and a physiological saline solution was given to the control group. After delivery, 10 offspring of the LPS-applied mother, nine offspring of the LPS+Salidrosideapplied mother and seven offspring of the control mother were sacrificed on postnatal Day 7 with ether anesthesia. The caspase enzyme located in apoptosis pathways of 10 percent neutral-buffered formalin fixed brain tissue was stained immunohistochemically, and apoptotic cells were counted. Results: No statistically significant difference was noted between the LPS+Salidroside group and the control group, while a statistically significant difference was noted between the LPS and LPS+Salidroside groups. It was observed that Salidroside reduced LPS induced apoptosis. Conclusion: The intended experimental neuroprotective effect of Salidroside usage was provided through the inhibition of apoptosis in a PVL-damaged brain

Effects of gestational exercise on hyperoxia-induced brain damage in the newborn

Aim: Preterm infants encounter hyperoxia relatively early on as they leave the intrauterine environment earlier than expected, while also being exposed to a higher level of hyperoxic stress due to insufficiencies in their antioxidant defense mechanisms. With that in mind, we investigate whether running exercises performed during pregnancy can contribute to the development of tolerance to neonatal hyperoxic brain damage. Method: While two female rats maintained a sedentary pregnancy, one female rat performed the mandatory running exercise for 30 minutes for five days a week throughout the pregnancy. Following delivery, the sedentary rats and the exercised rat were kept together with their offspring for five days at oxygen concentrations above 80 percent in order to induce brain damage. The offspring were sacrificed on postnatal Day 7 and brain/body ratio measurements were obtained. Results: The brain/body ratios in the control, hyperoxia and exercise-hyperoxia groups were found to be median (IQR) 0.074(0.68-0.77), 0.065(0.06-0.067) and 0.064(0.060-0.068), respectively. The brain/body ratios of the offspring of the mothers in the hyperoxia group were found to be significantly lower than the control group (p=0.002), irrespective of exercise (p=0.007). No statistically significant difference was noted between the offspring of the sedentary and the exercised mothers in the hyperoxia group (p=0.94). Conclusion: Hyperoxia was found to result in lower brain mass relative to total body mass. This finding, which indicates the presence of microcephaly, reflects the negative effects of hyperoxia on brain development. Contrary to expectations, exercises performed during pregnancy had no significant effect on the brain/body weight ratio of the offspring

Can gestational exercise have a positive effect on cognitive functions resulting from brain injury? A rat study

Aim: The effects of gestational exercise on potential pathological conditions is not known yet.  Therefore, in the present study, it was aimed to evaluate the effects of forced running exercise on LPS-induced brain damage in pregnant rats. Method: Pregnant females in the experimental group were forced to exercise 30 min daily for five days a week. Lipopolysaccharide (LPS) induced brain injury model was created by administering 500 µg/kg body weight of LPS on gestational days 18 and 19.   To evaluate injury histopathologically, brain tissues were fixed at the postnatal day seven through transcardial perfusion (n=4 pups/group). When the remaining pups reached 30-day of age, Morris water maze test (MWM) was performed to assess memory and learning, open filed (OP) and elevated plus maze (EPM) for testing anxiety, and Porsolt test (PT) for evaluating depression. The groups were defined as brain injury group (BI, n=13) and exercise+brain injury group (E+BI, n=7).  Results: The results obtained from MWM test indicated that animals found the platform in a shorter duration and distance at the day five compared to the day three. However, there was no significant difference between the groups. No significant difference was found in OP test regarding the distance traveled, time spent at the margins, movement at the center and the time spent as immobile. However, in the EPM test, the offspring at the BI group displayed higher mobility and increased number of entry to the open arms compared to the E+BI groups (p=0.01).  There was no significant difference regarding mobility duration and total distance traveled in the PT test. Conclusion: In the present study, we tested the impact of gestational exercise using the brain injury model. The results of the EPM test suggests that the gestational exercise can suppress the stress factors in the pregnant females with brain injury leading to the prevention of hyperactivity-induced negative learning behavior

Epilepsy and drug-resistant epilepsy in children with cerebral palsy: A retrospective observational study

Purpose: The objective of this study was to determine risk factors for epilepsy and drug-resistant epilepsy (DRE) development in children with cerebral palsy. Method: Two hundred twenty-nine patients presenting to the pediatric neurology clinic and diagnosed as having cerebral palsy between November 2016 and November 2019 were included in the study. Medical histories and clinical, laboratory, and radiological findings were examined retrospectively from patient records in the hospital data system. Results: Girls represented 103 patients (45%) and boys 126 (55%). The patients' mean age was 8.39 +/- 4.54 years. Epileptic seizures were present in 120 (52.4%) patients and drug-resistant seizures in 64 (27.9%). The risk of epilepsy was significantly higher in patients with motor or speech impairment, with hearing impairment, or undergoing first seizure in the neonatal period. We also observed a higher risk of epilepsy in patients with psychiatric comorbidity, particularly autism spectrum disorder. The risk of epilepsy was also higher in patients with microcephaly or quadriplegic cerebral palsy and in patients with focal and generalized epileptiform abnormality on electroencephalograms (EEGs). However, no significant difference was identified when all these factors were evaluated in terms of the risk of developing DRE. Conclusion: Patients with cerebral palsy have high comorbid epilepsy rates. We think that the risk of epilepsy may be higher in patients undergoing first seizure in the neonatal period, with microcephaly, with quadriplegic type cerebral palsy, and with additional psychiatric comorbidity. The rate of DRE development was very low in patients with normal EEG findings or with only background rhythm abnormalities on first EEGs during neonatal seizures. This may be regarded as a good prognostic factor for nondevelopment of DRE. (C) 2020 Elsevier Inc. All rights reserved.WOS:0005880042000312-s2.0-85089799848PubMed: 3285836

Insulin Resistance and Other Comorbidities of Obesity as Independent Variables on Ventricular Repolarization in Children and Adolescents

Background: Obesity, a rapidly increasing global health problem in all age groups, is accepted as the basis for many chronic diseases through insulin resistance mechanism. This study aimed to examine whether insulin resistance and other comorbidities of obesity have an effect on the cardiac conduction system. Methods: The study included 50 obese and 47 healthy individuals aged 6–18 years. ECGs of all cases were taken; ECG waves and intervals were measured manually. Results: Of the obese group, 19 were boys (38%) and 31 were girls (62%), 27 were children (54%) and 23 were adolescents (46%), their ages were 11.3 ± 3.5 years. These particular characteristics were similar compared to the control group. However, in the obese group, the ECG parameters QTc (p = 0.001), QTd (p < 0.001), QTdc (p < 0.001), JTc (p < 0.001), Tp-e (p < 0.001), Tp-e/QT (p < 0.001), Tp-e/QTc (p < 0.001), Tp-e/JT (p < 0.001), and Tp-e/JTc (p < 0.001) were significantly longer. Twenty-five obese subjects (50%) had insulin resistance, when ECG parameters are compared to those without it, only JTc was significantly longer (332.3 ± 16.5 vs 321.7 ± 17.7 ms, p = 0.033). JTc duration mostly affected JT (p < 0.001) and QTc (p < 0.001). The 327 ms cut-off value of JTc indicated insulin resistance in the obese patients (p = 0.044) (sensitivity 60%, specificity 60%). Conclusion: Insulin resistance and other comorbidities of obesity may cause ventricular repolarization abnormalities at an early age. JTc, an ECG parameter, can be a guide in assessing ventricular repolarization abnormality and the risk of arrhythmia in these patients.

Electroencephalogram Abnormalities and Epilepsy in Autism Spectrum Disorders: Clinical and Electroencephalogram Findings

It has been known for several decades that epilepsy and autism spectrum disorders (ASD) are related to each other. Epilepsy frequently accompanies ASD. The purpose of this study was to investigate relationship between clinical and electroencephalogram (EEG) findings in ASD patients and to identify EEG characteristics that may create a disposition to epilepsy in ASD by examining differences in clinical and EEG findings between patients diagnosed with ASD without epilepsy and ASD with epilepsy. A total of 102 patients aged 2 to 18 years and diagnosed with ASD based on Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) diagnostic criteria between January 2017 and June 2019 were included in the study. Patients were assigned into two groups: (1) ASD with epilepsy and (2) ASD without epilepsy. Clinical findings were retrieved from patients' files, and EEG findings from first EEG records in the EEG laboratory at the time of diagnosis. EEG findings were defined as central, parietal, frontal, temporal, or generalized, depending on the location of rhythmic discharges. The incidence of epilepsy in our ASD patients was 33.7% and that of febrile convulsion was 4%. Generalized motor seizures were the most common seizure type. Epileptic discharges most commonly derived from the central and frontal regions. These abnormalities, especially frontal and central rhythmic discharges, may represent a precursor for the development of epilepsy in ASD patients.WOS:00071259210000

Reflex Epilepsy with Hot Water: Clinical and EEG Findings, Treatment, and Prognosis in Childhood

Hot water epilepsy (HWE) is a subtype of reflex epilepsy in which seizures are triggered by the head being immersed in hot water. Hot water or bathing epilepsy is the type of reflex epilepsy most frequently encountered in our clinic. We describe our patients with HWE and also discuss the clinical features, therapeutic approaches, and prognosis. Eleven patients (10 boys, 1 girl), aged 12 months to 13 years, admitted to the pediatric neurology clinic between January 2018 and August 2019, and diagnosed with HWE or bathing epilepsy based on International League Against Epilepsy (ILAE)-2017, were followed up prospectively for similar to 18 months. Patients' clinical and electroencephalography (EEG) findings and treatment details were noted. All 11 patients' seizures were triggered by hot water. Age at first seizure was between 2 months and 12 years. Seizure types were generalized motor seizures, absence, and atonic. EEG was normal in two patients, but nine patients had epileptiform discharges. Magnetic resonance imaging of the brain was performed and reported as normal (except in one case). Histories of prematurity were present in two patients, unprovoked seizures in one, and low birth weight and depressed birth in the other. Patients with HWE have normal neuromuscular development and neurological examination results, together with prophylaxis or seizure control with a single antiepileptic drug, suggesting that it is a self-limited reflex epilepsy.WOS:0005717922000032-s2.0-85091574351PubMed: 3229476

Evaluation of neuronal damage following hypoxic-ischaemic brain injury in acute and early chronic periods in neonatal rats

This study was undertaken to investigate the effects of neonatal cerebral hypoxic-ischaemic brain injury (HIBI) in acute and early chronic phases in the rat. HIBI was induced in 7-day-old rat pups by ligation of the right common carotid and then the pups were exposed to 1 h of hypoxia in 8% oxygen. They were divided into two groups: 1-day (acute phase, in the first 24 h) and 5-day (early chronic phase, 120 h). Neuropathological evaluation was performed using the hippocampus, cerebral cortex and basal ganglia on the coronal plane. The following values were obtained: (i) the ratio of the infarcted area; (ii) hemispheric atrophy/asymmetry; (iii) patchy lesions confined to the thalamus, caudate and putamen; (iv) the ratio of damaged neurons to all neurons; and (v) the percentage of apoptotic neurons relative to the total neurons in all brain areas. HIBI-induced global cerebral damage and cellular damage findings did not significantly differ between the two groups. However, they showed a tendency to recover/deteriorate in both acute and early chronic phases. The ratio of ipsi- and contra-lateral hemisphere infarct areas (20.7 and 15.7% vs. 40.1 and 26.7%, respectively), basal ganglia patchy lesion ratio (27.5 vs. 36.7%) and hemispheric atrophy/asymmetry (92.4 vs. 84.7%) were found to be lower in the rat pups in the chronic phase than those in the acute phase. In contrast, increases in the ratio of damaged neurons (16.7 vs. 13.3% in the cerebral and dorsal hippocampus, respectively) and in the ratio of apoptotic neurons (ipsi-lateral: 18 vs. 6%; contra lateral hemispheres: 3.5 vs. 1.7%, respectively) were recorded. It is concluded that cellular damage tends to deteriorate (damaged and apoptotic neurons) while global damage (cerebral infarct and patchy damage) improves with the progression of HIBI. However, further studies are needed in order to elucidate this process. Copyright © 2005 John Wiley & Sons, Ltd

Relation of subepicardial adipose tissue thickness and clinical and metabolic parameters in obese prepubertal children

Background: The measurement of subepicardial adipose tissue thickness (SATT) has been found to be related to insulin resistance (IR) in adults. Until now, the association between SATT and IR has not been evaluated in obese prepubertal children. We aimed to determine the relation of SATT with clinical anthropometric and metabolic parameters and to provide cutoff value of SATT associated with IR in obese prepubertal children
