OBJECTIVES Although diffusion tensor imaging (DTI) is widely studied to assess the motor outcome after ischaemic stroke, there is paucity of data regarding outcomes of intracerebral haemorrhage (ICH). The aim of this study was to determine the DTI data from different locations along the corticospinal tract (CST) and association to motor outcome. METHODS(More)
Spontaneous intracerebral hemorrhage (ICH) is associated with high rates of mortality and morbidity. Thus, the identification of novel therapeutic agents for preventing strokes and attenuating poststroke brain damage is crucial. Dexamethasone (DEX) is used clinically to reduce edema formation in patients with spinal cord injury and brain tumors. In this(More)
Most trigeminal neuralgia is attributable to vascular compression of the root entry zone of the trigeminal nerve at the pons. Only about 5-10% of trigeminal neuralgia cases are caused by direct compression by ipsilateral cerebellopontine angle tumors. Trigeminal neuralgia caused by contralateral posterior fossa tumors are extremely rare. Cases in which(More)
The cellular events in traumatic brain injury (TBI) are complicated, and the factors mediating neurotrophins to protect and repair the injured brain cells are only beginning to be identified. This study examined the effect of dexamethasone (DEX) on neurotrophin-3 (NT-3) expression following TBI. Levels of NT-3 mRNA and protein in rat hippocampus were(More)
Nerve growth factor (NGF) is well-established as a trophic factor that plays a crucial role in neuroregeneration and plasticity after brain insults. Dexamethasone (DEX), a powerful glucocorticoid steroid, has long been used in the clinical management of neurological disorders. We examined the relationship between NGF and DEX after an ischemic insult to the(More)
BACKGROUND/PURPOSE In patients with traumatic brain injury, the degree of brain midline shift is related to prognosis. In this study, we evaluated the impact of the presence of a preoperative brain midline shift on the Glasgow Coma Scale (GCS) scores and muscle power (MP) improvement after cranioplasty. METHODS In this 6-year retrospective cohort study,(More)
Stroke is a common cause of death and severe disability among adults in developed countries. Cigarette smoking adversely affects human health in many ways and is considered to be a risk factor for a stroke. However, the mechanism that determines the relative importance of neurotrophins in this process remains unclear. To study the effect of chronic(More)
A 23-year-old male presented with a parasellar lesion which was suspected as disseminated intracranial germ cell tumour. The diagnosis of germinoma was made using immunohistochemistry from percutaneous trans-foramen ovale biopsy. This report describes the role of neuronavigation-guided biopsy through the foramen ovale for lesions in the parasellar region.
Symptomatic thoracic compression fracture is one of the most common causes of back pain in elderly. Although vertebroplasty is widely utilized in patients when conservative treatment fails, we introduced an alternative percutaneous technique for the treatment of thoracic compression pain. This in a retrospective study. The analysis was performed on 28(More)
