Association of hyperventilation-induced heart rate variability and sudden unexpected death in epilepsy in drug-resistant epilepsy.

Background:  Within the general epilepsy population, the incidence of Sudden Unexpected Death in Epilepsy (SUDEP) ranges from approximately 0.35 to 2.3 per 1,000 individuals per year.

Infraclavicular Catheter in MELAS Syndrome for Analgesic Purposes.

MELAS syndrome is defined as mitochondrial myopathy accompanied by encephalopathy, lactic acidosis, myoclonus, stroke-like episodes. It has a progressive course, multi-systemic effects and severe complications. Myoclonic contractions are unresponsive to many anti-epileptic drugs; these contractions and spasms may lead to severe pain.

Evaluation of comorbid diseases in obstructive sleep apnea syndrome.

Objective: It is known that obstructive sleep apnea syndrome affects many systems due to hypoxemia and hypercarbia. We aimed to demonstrate with the utilization of well-standardized questionnaire tools and electrophysiological tests that cognitive impairment, depression, autonomic dysfunction, and metabolic syndrome may occur in association with obstructive sleep apnea syndrome.

Methods: The electrophysiological examination protocol of autonomic nervous system functions was performed with sympathetic skin response and R-R Interval.

Pharmacoresistant seizures in neurofibromatosis type 1 related to hippocampal sclerosis: Three case presentation and review.

Neurofibromatosis type 1 (NF1) is an autosomal dominantly inherited disorder, with an estimated prevalence of 1 in 3000-4000 people. Seizures occur 4-7% of individuals with NF1, mostly due to associated brain tumors or cortical malformations. Hippocampal sclerosis (HS) in the patients with NF1 has been reported very rarely and only 15 patients were found in review of English literature.

Impaired Visual Habituation in Idiopathic Generalized Epilepsy with Photosensitivity Patients.

Introduction: In this study, our goal was to analyze further the cortical excitability levels in idiopathic generalized epilepsy (IGE) patients with and without photosensitivity.

Methods: Forty-two patients (16 men and 26 women; mean age 30±8 years; range: 18-43 years) with IGE and thirty healthy age-matched control subjects (15 men and 15 women; mean age 35±3 years; range: 20-45 years) were enrolled for the investigation. We investigated the following two groups: 18 subjects with IGE with photosensitivity (IGE+PS), and 24 patients with IGE without photosensitivity (IGE-PS).
