OBJECTIVE To enable physicians to remain informed of secondary GKR after multiple surgical choices. This study compares gamma knife radiosurgery (GKR) as a first and a second treatment for the management of medically refractory idiopathic trigeminal neuralgia (TN). METHODS Between May 1998 and May 2008, a total of 86 patients with idiopathic TN underwent(More)
INTRODUCTION   The use of deep brain stimulation (DBS) is growing. While these patients may suffer from traumatic brain injuries, treatment guidelines for these patients have not yet been reported. This case report demonstrates a strategy for traumatic brain injury after DBS implantation. CLINICAL PRESENTATION   A 46-year-old man underwent bilateral DBS(More)
OBJECTIVES The purpose of this retrospective study was to evaluate causes contributing to surgical resectability and seizure outcomes depending on various clinical and surgical factors. PATIENTS AND METHODS The records of 44 patients with gangliogliomas surgically treated between April 1986 and March 2007, were retrospectively reviewed to assess(More)
OBJECTIVES The unfavorable surgical results that have been reported with insular epilepsy surgery may be related to inadequate monitoring. Insular epilepsy surgery requires the precise monitoring and tailored removal of the epileptic zone. The purposes of this study were to precisely monitor the hidden cortex and determine the effectiveness of using(More)
Recent evidence has demonstrated associations between the single nucleotide polymorphism (SNP) rs11614913 in miR-196a2C>T and various pathologies. A main target of miRNA-196a is annexin A1 (lipocortin1, ANXA1), which is associated with increased multiple malignant tumors in brain models of ischemia and reperfusion injury. To determine the effects of miRNA(More)
BACKGROUND Trigeminal neuralgia (TN) is primarily diagnosed by symptoms and patient history. Magnetic resonance (MR) imaging can be helpful in visualizing the neurovascular compression of the trigeminal nerve in TN patients, but the current parameters used as diagnostic markers for TN are less than optimal. The aim of this study is to assess whether the(More)
Epilepsy from hamartoma of the floor of fourth ventricle (HFFV) is very rare, starting in neonate or infantile period, good response to surgery. We report a 3-month-old boy with episodes of medically intractable abnormal eyelid blinking and hemifacial seizure. The episodes began from the first day of life and were unresponsive to medication. A magnetic(More)
OBJECTIVE To assess the effect of relative lower amplitude and frequency for globus pallidus internus (GPi) deep brain stimulation (DBS) of cervical dystonia (CD). MATERIALS AND METHODS Between February 2005 and October 2008, 14 patients diagnosed with CD underwent bilateral GPi DBS and all the patients received low-frequency stimulation and were followed(More)
Ablation of the globus pallidus internus (GPi) and thalamotomy have been extensively used in the past. Posteroventral GPi deep brain stimulation has been considered as a treatment for dystonia. However, to date, there is no report in the literature of any dystonia patient who underwent GPi deep brain stimulation who had previously undergone staged bilateral(More)
We conducted a case-control study to investigate whether vascular endothelial growth factor (VEGF -2578, -1154, -634, and 936) and kinase insert domain containing receptor (KDR -604, 1192, and 1719) polymorphisms are associated with moyamoya disease. Korean patients with moyamoya disease (n = 107, mean age, 20.9±15.9 years; 66.4% female) and 243 healthy(More)
