Objective: In obstructive sleep apnea syndrome (OSAS), any of the activated neural, vascular, hemodynamic, metabolic, inflammatory, and thrombotic mechanisms may be related to increased cerebrovascular disease and risk of death; however, the possible pathophysiological process between obstructive sleep apnea syndrome and stroke has not been clearly explained. We hypothesize that alterations in vasomotor reactivity in patients may be responsible for their altered cerebral blood flow, and may contribute to the increased risk of ischemic stroke.

Methods: A total of 30 untreated patients with severe obstructive sleep apnea and 26 control subjects were included in the study.

Aim: The objective of our study was to investigate nerve conduction in normoglycemic obese children.

Methods: A total of 60 children with obesity (30 female and 30 male) and 30 healthy children (15 female and 15 male) were enrolled in the study. Insulin resistance (IR) and other metabolic disturbances were investigated and nerve conduction was measured in all participants.

Migraine is a neurovascular disorder characterized by autonomic nervous system dysfunction and severe headache attacks. Studies have shown that changes in the intracranial vessels during migraine have an important role in the pathophysiology. Many studies have been conducted on the increased risk of stroke in patients with migraine, but insufficient data are available on the mechanism underlying the increase.

Aim: Peripheral nerve regeneration is often blocked by scar formation and misdirection of axon sprouts. The aim of this study is to evaluate electrophysiological and histopathological effects of low-dose radiation therapy on the prevention of intraneural scar formation in peripheral nerve injury.

Material And Methods: In this experimental study, twenty rats were randomly divided into two groups.

Objective: The aim of this study was to determine whether patients who faint earlier in the course of a tilt table study represent a separate population with a poorer prognosis or different pathophysiology. We analyzed differences across patients with different syncopal times on the tilt-table study to answer this question.

Methods: This was a retrospective, approved, chart review.

Background/aims: We aimed to electrophysiologically evaluate the autonomic function in acromegalic patients using sympathetic skin response (SSR) as a reflection of the sympathetic sudomotor activity and RR interval variation (RRIV) as an indicator of the cardiovagal autonomic function.

Methods: The study group consisted of 18 male acromegalics, and the control group was composed of 18 age- and sex-matched healthy subjects. Participants underwent SSR and RRIV tests.

Objective: To investigate alterations in P300 auditory event-related potentials in children with obesity to detect changes in cognitive functions.

Method: A total of 50 children with obesity and 23 age- and sex-matched healthy control subjects were included in the study. Laboratory tests were performed to detect dislipidemia and insulin resistance (IR).

Objective: Corticosteroid injection into the carpal tunnel is frequently used for the treatment of carpal tunnel syndrome (CTS). Steroids are usually mixed with local anesthetics, which have positive effects that can aid the treatment of CTS by inhibiting the spontaneous discharge ability of excitable cells. The aim of this study was 3-fold: (1) to determine the efficacy of triamcinolone acetonide injection in the treatment of CTS, (2) to determine the efficacy of procaine hydrochloride (HCl) in the treatment of CTS, and (3) to compare the efficacy of triamcinolone acetonide and that of procaine HCl in the treatment of CTS.

Objective: The prognostic value of electrophysiology and its significance in the prediction facial function outcome in facial palsy patients remains unclear because of the different methodologies used in previous studies. We aimed to establish the prognostic value of electrophysiological testing in a group of patients with facial palsy.

Methods: We prospectively analyzed facial nerve electrophysiology results and compared them with the House-Brackmann scale in 65 patients.

Objectives: Hot water epilepsy (HWE) or bathing epilepsy is one of the reflex epilepsies induced by hot water pouring over the head, face, neck, or trunk during bathing. The aim of this study was to demonstrate the clinical and electroencephalographic features and the management alternatives of the patients with HWE.

Methods: The age of seizure onset, duration of seizure, family history, interictal and postictal electroencephalography findings, triggering temperature of water, type of seizure, medication, and follow-up results were evaluated for each patient.

Aim: This study was planned for detailed evaluation of electrophysiological findings in patients with adult TCS.

Material And Methods: Patients were retrospectively assessed for clinical, radiological and electrophysiological data between 1999 and 2008. Tibial somatosensorial evoked potentials, needle electromyography, nerve conduction studies and late responses (H reflex and F response) were studied in thirty (1 female, 29 males) TCS patients diagnosed by lumbar magnetic resonance imaging.

The study was designed to investigate the autonomic dysfunction in fibromyalgia syndrome (FMS) by recording sympathetic skin response (SSR) from palmar, plantar and genital regions. The second aim was to evaluate the relation between sexual problems and autonomic dysfunction in FMS. SSR potential was recorded from palmar, plantar and genital regions in 28 married, female FMS patients and 18 married, healthy females.
