The aim of the study described here was to analyze findings in 15 cases who were admitted with nonconvulsive status epilepticus (NCSE) and whose EEGs featured atypical triphasic waves (ATWs). We also investigated whether ATWs are useful for diagnosing this condition. Mental status was assessed, and EEGs were recorded during/after the antiepileptic drug(More)
Even though stroke is known to be a common cause of status epilepticus (SE), the types of stroke or SE that may be associated are not yet clearly defined. The aims of this study were to assess the timing and type of SE in stroke patients and to observe the effects of stroke and the type of SE on the response to treatment and mortality. From May 1998 to May(More)
Delayed administration of vascular endothelial growth factor (VEGF) promotes functional recovery after focal cerebral ischemia. However, early intravenous injection of VEGF increases blood-brain barrier (BBB) leakage, hemorrhagic transformation and infarct volume whereas its application to cortical surface is neuroprotective. We have investigated whether or(More)
The aim of this study was to evaluate the computed tomography (CT) and magnetic resonance imaging findings (MRI) of asymptomatic remote cerebellar hemorrhage (RCH) at the preoperative, early postoperative, and postoperative period. A total of 983 consecutive adult patients who underwent supratentorial craniotomies were included in the study. The ethics(More)
BACKGROUND AND PURPOSE During the hyperacute phase of stroke, multiple hypointense vessels were identified specifically in the ischemic territory on gradient-echo T2*-weighted MR images (GRE-T2* WI) at 3T. The area was named a "region of multiple hypointense vessels (RMHV)." The aim of this study was to assess the usefulness of RMHV for the diagnosis of(More)
The aim of the study is to analyze diffusion tensor imaging (DTI) characteristics of the Guillain-Mollaret triangle (GMT) in patients with hypertrophic olivary degeneration (HOD) and to investigate their correlation with previously reported histopathology. DTI was performed in 10 patients diagnosed with HOD. Fractional anisotropy, apparent diffusion(More)
BACKGROUND Patients with the syndrome of headache with neurological deficits and lymphocytosis (HaNDL) typically present with recurrent and temporary attacks of neurological symptoms and cerebrospinal fluid lymphocytosis. AIM AND METHODS To identify potential HaNDL-associated antibodies directed against neuronal surface and/or synapse antigens, sera of(More)
BACKGROUND The aim of this study was to investigate aortic atheromas in stroke subgroups. METHODS Two hundred consecutive subjects had acute ischemic stroke confirmed by diffusion-weighted imaging (DWI) (195 cases) or computerized tomography (5 cases). Multidetector computed tomographic angiography (MDCTA) (16- or 64-slice) was used to detect(More)
Infectious-immunogenic mechanisms have been proposed for the pathogenesis of the syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) [1]. To investigate this assumption, we performed immunohistochemistry and Western blot studies with sera and cerebrospinal fluid (CSF) of two HaNDL patients. Serum and CSF(More)
Osteopetrosis, or Albers-Schönberg disease, is a rare hereditary disease characterized by osteoclast dysfunction and consequent diminished bone resorption and disturbed bone building and remodeling, resulting in abnormally dense and brittle bones. Bone marrow failure, pathologic fractures, and neurologic deficits are common. Osteopetrosis is diagnosed on(More)
