OBJECT Spontaneous spinal epidural hematoma (SSEH) is a rare disease entity. Although many cases have been reported in the literature, controversy persists as to its origin, diagnosis, and timing of treatment. The authors conducted a study in patients treated in their hospital and report the results. METHODS Clinical data obtained in 35 patients with SSEH(More)
OBJECTIVE Stereotactic biopsy is a widely used surgical technique for the histological diagnosis of intracranial lesions. Potential risks of this procedure, such as hemorrhage, seizure, and infection have been established, and different risk factors have been characterized. However, these risks have been addressed by only few studies conducted in Asian(More)
Hypoxia is a common occurrence in brain tumors and traumatic brain injury. microRNA (miR)-1 participates in the regulation of brain development and neuronal function. Interestingly, miR-1 can mediate ischemia-induced injury to cardiomyocytes. This study was designed to evaluate the roles of miR-1 in hypoxia-induced insults to neurons and the possible(More)
The optimal postoperative management of pediatric intracranial ependymomas is controversial. We analyzed clinical prognostic factors for their influence on outcome in such children. Our retrospective series included 15 with supratentorial and 28 with infratentorial tumors. Twenty ependymomas were grade II, and 23 were anaplastic. Complete resection was(More)
Guanidine, the active ingredient extracted from Galega officinalis, is introduced as a ligand for imidazoline I2 receptor (I2R) because guanidine decreased plasma glucose via an activation of I2BR to increase glucose uptake into skeletal muscle isolated from Wistar rats. However, the signals for this action of guanidine remained obscure. In the present(More)
Congenital dermal sinuses are relatively uncommon, and result from abnormal neurulation. A lack of awareness about this problem causes these patients to manifest significant mortality and morbidity. Spinal intramedullary abscesses are rare and potentially devastating lesions. Intraspinal epidermoids are also unusual lesions. We report on a boy, aged 1 year(More)
BACKGROUND Glioblastoma multiforme (GBM) is the most aggressive type of glioma and carries the poorest chances of survival. There is therefore an urgent need to understand the mechanisms of glioma tumorigenesis and develop or improve therapeutics. The aim of this study was to assess the possible prognostic value of cyclin-dependent kinase 6 (CDK6) and the(More)
OBJECTS Among patients with medulloblastoma, an unrare aggressive central nervous system (CNS) tumor found mostly in the posterior fossa, drop metastasis from primary location to anatomically lower sites including whole spinal cord is known as a potential way for tumor to spread. There were already lots of extensive discussions regarding diagnosis and(More)
OBJECT Spinal cord injury without radiological abnormality (SCIWORA) was defined in the era when magnetic resonance (MR) images were not popularly used as diagnostic tools. Although it is generally accepted that MR imaging can effectively illustrate the level and severity of spinal cord injury in the acute phase of trauma, only a few reports of MR imaging(More)
Endodermal cysts of the central nervous system are unusual lesions. Most reported cysts develop in the spinal canal, whereas others, which occur intracranially, are usually located in the posterior fossa. Although endodermal cysts are considered congenital, a prenatal diagnosis has not been reported. In this report the authors present an extremely rare case(More)
