[Elastic modulus measured by spherical indentation used toward the clinical application of the brain stiffness].

Objective: Palpation of brain stiffness is one of techniques that leads to successful neurosurgical procedures. In order to evaluate brain stiffness quantitatively, we studied the potential clinical applicability of a spherical indenting tactile sensor.

Methods: The sensor had a spherical rigid indenter (diameter=5.

Postoperative quality of life outcome and employment in patients undergoing resection of epileptogenic lesions detected by magnetic resonance imaging.

The long-term postoperative improvement of quality of life (QOL) and employment were investigated in patients undergoing resection of epileptogenic lesions detected by magnetic resonance (MR) imaging to identify the associated preoperative factors. Thirty of 47 patients who underwent lesionectomy between 1987-2001 replied to questionnaires. Patients with extratemporal resection outnumbered those with temporal lobe resection.

Quantitative analysis of delayed neuronal death in the hippocampal subfields of SHRSP and SHR.

Transient forebrain ischemia and reperfusion induces delayed neuronal death (DND) in the hippocampal Cornu Ammonis 1 (CA1) subfield of stroke-prone spontaneously hypertensive rat (SHRSP). The vulnerability to DND is potentially related to the genetic susceptibility to stroke in this strain. To elucidate the mechanism of DND in SHRSP, however, it is essential to establish a method for quantitative evaluation of DND, which is not available yet.

Symptomatic hemorrhage associated with recurrent pilocytic astrocytoma with granulation tissue--case report.

A 51-year-old woman had been followed up for 10 years for recurrence of pilocytic astrocytoma 5 years after the initial treatment consisting of subtotal resection, chemotherapy, and radiation therapy. The patient presented with sudden onset of headache and vomiting. Computed tomography and T(2)*-weighted magnetic resonance imaging revealed hemorrhage in the tumor located in the right basal ganglia, thalamus, and hypothalamus.

[Clinical efficacy and cost benefit of oral antimicrobial prophylaxis with levofloxacin on neurological surgery].

Objective: The clinical efficacy and cost benefit of oral antimicrobial prophylaxis with levofloxacin (LVFX) on neurosurgical operation were evaluated.

Patients And Methods: Fifty patients undergone burr hole drainage for chronic subdural hematoma were enrolled into this study. These patients had preoperative intravenous drip infusion of 1.

A case of unknown origin subarachnoid hemorrhage immediately following drainage for chronic subdural hematoma.

A 56-year-old man treated with anticoagulants complained of a gradually worsening headache. A left chronic subdural hematoma (CSH) was shown by head computed tomographic (CT) scans and the operation, one burr hole surgery under local anesthesia, itself was performed uneventfully. However, immediately after we began draining the hematoma at the patient's bedside, the patient complained of a sudden headache.

Extracranial vertebral artery aneurysm ruptured into the thoracic cavity with neurofibromatosis type 1: case report.

Objective And Importance: We are sometimes involved in the care of patients with neurofibromatosis Type 1 because of the associated disorders of cervicocerebral vessels. However, extracranial vertebral artery aneurysm in neurofibromatosis Type 1 is very rare. We present the first reported case of a rupture of an extracranial vertebral artery aneurysm into the thoracic cavity in a patient with neurofibromatosis Type 1.
