OBJECTIVES A simple clinical score (ABCD(2) score) has been introduced to triage TIA patients with a high early risk of stroke. External validation studies have yielded inconsistent results regarding the predictive ability of the ABCD(2) score. We aimed to prospectively validate the former score in a multicenter case series study. METHODS We prospectively(More)
OBJECTIVES A chronic state of impaired cerebral and cervical venous drainage, termed chronic cerebrospinal venous insufficiency (CCSVI), has recently been implicated in the pathogenesis of multiple sclerosis (MS). We performed a color-coded Doppler sonography case-control study to externally validate the CCSVI criteria. METHODS We prospectively evaluated(More)
Assessment of respiratory muscle weakness is important at all stages of myasthenia gravis. The maximal voluntary ventilation (MVV) is an objective dynamic method for measuring the working capacity of respiratory muscles. The clinical value of this method was studied in 24 newly diagnosed patients with myasthenia gravis, classified according to Osserman(More)
BACKGROUND Epidemiological data on subarachnoid haemorrhage incidence and case-fatality rates are scarce in the south-eastern Mediterranean region. We conducted a population-based study in Evros Province, located in north-eastern Greece, to determine subarachnoid haemorrhage incidence over a 5-year period (2001-2005). METHODS Evros Province has a(More)
Anticoagulant therapy is recommended for the secondary prevention of stroke in patients with atrial fibrillation (AF). T he identification of patients at high risk for early recurrence, which are potential candidates to prompt anticoagulation, is crucial to justify the risk of bleeding associated with early anticoagulant treatment. The aim of this study was(More)
Neovascularization in atherosclerotic plaques plays an essential role in the progression and rupture of plaques. Vascular endothelial growth factor (VEGF) is an important angiogenic factor. Echomorphologic evaluation of carotid plaques using computer-assisted imaging was found to have a good correlation with the histology of the lesion. The aim of this(More)
The aim of this study was to investigate sleep architecture in stroke patients, and correlate possible disturbances with the topography, severity and outcome of stroke and the presence of sleep-disordered breathing (SDB). In total, 62 acute stroke patients and 16 age- and gender-matched hospitalised controls underwent polysomnographic studies. Sleep(More)
BACKGROUND AND AIM The diagnosis of peripheral diabetic neuropathy is based on clinical examination. Nerve conduction study (NCS) enables earlier diagnosis, but it is demanding and requires specialised personnel. In an attempt to simplify the procedure, this study aimed to identify a new electrophysiological index, which might correlate with results(More)
BACKGROUND AND PURPOSE The diagnostic utility of transesophageal echocardiography (TEE) in patients with cryptogenic ischaemic stroke (IS) or transient ischaemic attack (TIA) remains controversial. METHODS A systematic review and meta-analysis was performed according to PRISMA guidelines to estimate the pooled prevalence of potential cardioembolic causes(More)
BACKGROUND The optimal timing to administer non-vitamin K oral anticoagulants (NOACs) in patients with acute ischemic stroke and atrial fibrillation is unclear. This prospective observational multicenter study evaluated the rates of early recurrence and major bleeding (within 90 days) and their timing in patients with acute ischemic stroke and atrial(More)
