Although intravenous delivery of mesenchymal stem cells (MSCs) prepared from adult bone marrow reduces infarction size and ameliorates functional deficits in rat middle cerebral artery occlusion models, there are few reports of MSC treatment in global cerebral ischemia. We utilized a global cerebral ischemia model induced by arresting the heart with a(More)
The sensitivity of susceptibility-weighted magnetic resonance (MR) imaging was compared with conventional MR sequences, including T(2)*-weighted imaging, and computed tomography for the detection of cerebral hemorrhages in 15 patients with head injury. Susceptibility-weighted imaging detected a mean of 76+/-52 (total 1132) hypointense spotty lesions,(More)
BACKGROUND AND PURPOSE Dot-like low intensity spots (a dot-like hemosiderin spot: dotHS) on T2*-weighted MR images (T2*WI), which is regarded as a sensitive method for hemosiderin detection, have been histologically diagnosed as old microbleeds associated with microangiopathies. The clinical significance of the dotHS, however, is still under debate.(More)
Free radicals play major roles in the pathogenesis of tissue damage in many diseases and clinical conditions, and the removal of free radicals may offer a treatment option. Several modulators of free radical scavenger pathways have been developed and some have progressed to clinical trials. One such agent, edaravone,(More)
OBJECTIVE Stent placement for the treatment of carotid artery stenosis may cause hemodynamic instability that induces ischemic complications for patients with bilateral carotid lesions. We carried out this study to define predictors of persistent hypotension after carotid stenting. METHODS Thirty-three lesions in 31 consecutive patients (mean age, 69.2(More)
BACKGROUND AND PURPOSE Dot-like low intensity spots (dot-like hemosiderin spots: dotHSs) on gradient echo T2*-weighted MRI have been histologically diagnosed to represent old cerebral microbleeds associated with microangiopathies. They have also been correlated to the fragility of small vessels and the tendency to bleed. Therefore, a substantial number of(More)
Idiopathic systemic capillary leak syndrome (ISCLS) is a rare condition that is characterized by unexplained episodic capillary hyperpermeability due to a shift of fluid and protein from the intravascular to the interstitial space. This results in diffuse general swelling, fetal hypovolemic shock, hypoalbuminemia, and hemoconcentration. Although ISCLS(More)
We present the case of a 20-year-old female who underwent foramen magnum decompression and laminectomy of C1-C3 as well as incision of only the outer layer of the dura, for her symptomatic Chiari malformation (type 1) with syringomyelia, at the age of 9 years. She required additional surgery with removal of regenerated bone and dural plasty for the(More)
OBJECTIVE In patients with severe traumatic brain injury (TBI), a randomized controlled trial revealed that outcomes did not significantly improve after therapeutic hypothermia (TH) or normothermia (TN). However, avoiding pyrexia, which is often associated with intracranial disorders, might improve clinical outcomes. The objective of this study was to(More)
BACKGROUND AND PURPOSE Dot-like low-intensity spots (dot-like hemosiderin spots: dotHSs) on gradient echo T2*-weighted (-w) brain magnetic resonance imaging (MRIs) are frequently associated with cerebral small vessel disease (SVD), including deep intracerebral hemorrhages and lacunar infarctions. This study investigated how numbers of newly appeared dotHSs(More)
