Disability a b s t r a c t Introduction: Cutaneous silent period (CSP) is an inhibitory spinal protective refl ex and its afferents consist of A-delta nerve fi bers. We aimed to evaluate patients with fi bromyalgia (FM) and healthy controls to determine any differences between the groups in terms of CSP duration and latency, and if present, to determine(More)
PURPOSE To determine the normal anatomical features and variations of the vertebrobasilar circulation and its branches in patients who underwent multidetector computed tomography (CT) or magnetic resonance (MR) angiographies of the brain. METHODS 135 patients (male, 83 and female, 52; mean age, 50.1 years) who underwent CT (n = 71) or MR (n = 64)(More)
OBJECTIVE Primary aim is to compare the diagnostic value of contrast-enhanced 3D GRE T1-weighted sequences with unenhanced MR venography and conventional magnetic resonance imaging (MRI), in detection of dural venous sinus (DVS) and cortical venous thrombosis; secondary aim is to determine the relationship between DVS thrombosis/site and gender, age,(More)
We have read the case report of Oge et al. with interest (2). They evaluated the carpal tunnel range/carpal tunnel area ratio among patients with carpal tunnel syndrome and the control group, together with the median nerve area and its palmar bowing of the transverse carpal ligament. An increase in the ratio of carpal tunnel range/carpal tunnel area were(More)
OBJECTIVE To evaluate the validity of early (within 3 wk) and late-term (after 3 wk) electroneurography (ENoG) findings in Bell's palsy (BP) to predict the prognosis. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS Patients with peripheral facial paralysis with no identified cause. All patients were given the same(More)
AIM To explore amplitude and latency-check size function in multiple sclerosis (MS) patients without optic neuritis history. METHODS Thirty-six MS patients and 21 control subjects were included. Pattern visual evoked responses to ive check sizes (2°, 1°, 30', 15', and 7') were recorded. RESULTS P100 amplitudes were significantly reduced in 2°, 1° and 7'(More)
The present study was designed to describe the socio-demographic, clinical, and polysomnographic features of patients diagnosed with narcolepsy in our sleep center. This retrospective cross-sectional study was conducted on 181 patients diagnosed with narcolepsy based on the results of clinical evaluation, polysomnography (PSG), and multiple sleep latency(More)
A 22-year-old male had a meniscopathy operation using spinal anesthesia. After the operation, the patient reported a throbbing headache. His brain computed tomography (CT) showed subarachnoid hemorrhage (SAH) and hyperdense dural venous sinuses suspicious for thrombosis. Filling defects were observed in the superior sagittal and right transverse sinuses on(More)
