Purpose: Information on COVID-19 vaccine tolerance and complications in patients with epilepsy is not yet sufficient to provide a recommendation for vaccination guidelines. The aim of this study was to investigate the effect of two types of COVID vaccines currently used in Turkey (mRNA vaccine from Pfizer/BioNTech and inactivated vaccine from Sinovac) on epileptic seizures.

Methods: We included 318 patients with epilepsy who were admitted to our epilepsy outpatient clinic.

Introduction: Migraine and epilepsy are two episodic disorders that share common pathophysiological mechanisms. The aim of our research was to assess the possible shared etiopathogenesis by analyzing the relations of headache, and seizure triggers, based on information obtained from a national cohort surveying the headache characteristics of 809 patients who had been diagnosed with idiopathic/genetic epilepsy.

Material And Methods: Our study utilized data from a multi-center, nationwide investigation of headaches in 809 patients with idiopathic/genetic epilepsy.

Introduction: Decision-making behaviors of patients with mesial temporal lobe epilepsy (MTLE) is a subject that has been studied frequently. However, determining the neuropsychological profiles of patients with different types of epilepsy is also important. Our main purpose was to examine the decision-making behaviors of patients with posterior cortex epilepsy (PCE) through the assumptions of somatic marker hypothesis (SMH) and to compare their performances with those of a MTLE group and a control group.

Background: Migraine without aura (MwoA) is a very frequent and remarkable comorbidity in patients with idiopathic/genetic epilepsy (I/GE). Frequently in clinical practice, diagnosis of MwoA may be challenging despite the guidance of current diagnostic criteria of the International Classification of Headache Disorders 3 (ICHD-3). In this study, we aimed to disclose the diagnostic gaps in the diagnosis of comorbid MwoA, using a zone concept, in patients with I/GEs with headaches who were diagnosed by an experienced headache expert.

Purpose: Continuous oxygen therapy to compensate for decreased oxygen saturation in the blood is a life-saving treatment used in case lung involvement. Excess oxygen delivery was reported to be a common situation, in which about 50% of the patients showed hyperoxemia and 4% in severe hyperoxemia. In this work, we investigated the effects of hyperoxia on the rat kidneys and whether tadalafil has an effect to reduce this damage.

Article Synopsis
  • The study investigates the use of F-FDG PET/MRI combined with EEG to analyze the metabolic patterns in patients with gray matter heterotopia (GMH) and epilepsy.
  • The research involved 30 patients, evaluating the metabolism of heterotopic nodules and identifying the epileptogenic zone (EZ) through imaging and clinical methods.
  • Results showed varied metabolic activity in heterotopic nodules, with a strong correlation between imaging findings and the clinical EZ in most cases, indicating the significance of F-FDG PET/MRI in epilepsy assessment.

Aim: To evaluate the patients who had epilepsy surgery and pathologically proven focal cortical dysplasia (FCD) in order to further classify and discuss electroencephalography (EEG) findings in different pathological subtypes.

Material And Methods: This study included 19 refractory epilepsy patients who underwent surgery between 1999 and 2017 in the Istanbul Faculty of Medicine. Demographic data, preoperative examinations, scalp video EEGs, and postoperative outcomes were evaluated retrospectively.

Article Synopsis
  • The study looked at how tadalafil, a medicine, helps protect against damage caused by too much oxygen in rats.
  • Rats were divided into three groups: one group got no treatment, one group was exposed to high oxygen, and the last group got high oxygen plus tadalafil.
  • The results showed that while high oxygen increased some protective enzymes in the body, giving tadalafil made those levels go down and also reduced some symptoms in the rats' body parts.

Temporal lobe epilepsy (TLE) is one of the most common forms of focal epilepsy. Anterior temporal lobectomy (ATL) leading to high rate of seizure freedom is a safe and well-established procedure in TLEs. Cranial nerve deficits, especially for oculomotor, trochlear and facial nerve were reported as a complication after ATL.

Article Synopsis
  • The study investigates the relationship between headaches and idiopathic/genetic epilepsy (I/GE) in patients aged 6-40 years, focusing on headache prevalence and characteristics among these individuals.
  • Out of 809 patients, 62.8% reported headaches, with 87.4% experiencing interictal headaches and 41.2% having migraines; the analysis identified distinct clusters based on headache and epilepsy features for both adults and children/adolescents.
  • Two primary clusters emerged: one included patients with a family history of headaches and specific seizure types (like juvenile myoclonic epilepsy), while the other contained patients with different characteristics, including those with self-limited epilepsy and generalized tonic-clonic seizures. *

We aimed to compare the effectiveness of 15- and 30-W holmium:yttrium-aluminum-garnet (Ho:YAG) laser devices used in the treatment of pediatric kidney stones. Eighty-six consecutive pediatric patients who underwent retrograde intrarenal surgery (RIRS) between February 2010 and August 2020 were enrolled in the study. After exclusion criteria were applied, the data of 79 children were evaluated retrospectively.

Introduction: We retrospectively assessed the role of ureteral wall thickness (UWT) at the ureteral stone site in predicting the stone-free status and the complication rates in children undergoing semi-rigid ureterorenoscopy (URS).

Patients And Methods: The children who underwent URS and had undergone non-contrast abdominal computerized tomography before the URS were included in the study. The following protocol was used to determine the outcome.

Article Synopsis
  • The study aimed to analyze the types, causes, and rates of epilepsy in patients with abnormal brain activity located in the posterior cerebral region, as well as cognitive and behavioral issues linked to these abnormalities.
  • A sample of 346 patients, aged 1 to 21, was evaluated from a larger group of 3,500 who underwent EEG testing, revealing a significant number of patients had histories of seizures or other non-epileptic conditions.
  • Results indicated that most patients showed isolated epileptiform activity in the posterior TPO region, suggesting a need for further research on the connections between localized brain activity and various clinical conditions.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) (polyglandular endocrinopathy type 1) is a rare autosomal recessive disorder caused by mutations in the autoimmune regulator gene (AIRE). The major clinical features of APECED are hypoparathyroidism, adrenal insufficiency (Addison disease), and chronic mucocutaneous candidiasis. This disease is also associated with multiple other and uncommon autoimmune (autoimmune hepatitis, autoimmune enteropathy, atrophic gastritis with or without pernicious anemia, gonadal failure, diabetes mellitus, hypothyroidism, functional hyposplenism), ectodermal (alopecia and vitiligo), and inflammatory (intestinal lung disease, nephritis) features.

Objectives: Our study aims to compare demographics, clinical features and postsurgical outcomes between early and late-onset patients with medically refractory temporal lobe epilepsy (TLE) related to mesial temporal sclerosis (MTS).

Patients And Methods: Seventy-one patients admitting to the Epilepsy Clinic of Istanbul University-Cerrahpasa, Cerrahpasa Faculty of Medicine between 1995-2015, who were diagnosed with refractory TLE related to MTS, were included in our study. All of these patients were resistant to medical treatment, and thus candidates for, or underwent surgery, and had no pathology other than MTS in their cranial magnetic resonance imaging (MRI).

Background: Temporal neocortex which appears normal on magnetic resonance imaging (MRI) may have pathological tissues in low-grade gliomas (LGG) of pure mesial temporal area. Resection of the cortex may be required together with mesial temporal glioma for satisfactory seizure and oncological outcome. The aim of this study was to explore the presence of any pathological tissue on the temporal cortex that appeared normal on preoperative MRI in patients with pure mesial temporal LGGs.
