Hairdresser dystonia is one of the occupational dystonias and task-specific movement disorders occurring as a result of long-term repetitive cutting with scissors. The task-specific dystonia manifests itself as a loss of voluntary motor control during extensive practice of cutting requiring a high level of technical proficiency. The prevalence rate of hairdresser dystonia is not well-known worldwide.

This report is about our additional embolization method using combination therapy.
Case Presentation: Five consecutive cases of direct CCF were presented; two were caused by aneurysms and three by head injuries.
Objective: Endovascular coil embolization for anterior communicating artery (ACoA) and anterior cerebral artery (ACA) aneurysms is associated with high total and near-total occlusion rates, but the complication rate is high. The development of newer endovascular technologies may improve the clinical outcomes. This study investigated the status of endovascular treatment of ACoA and ACA aneurysms by comparing our results with past reports.

Bilateral occurrence of VAD is generally considered rare, but the number of reports of bilateral VAD has been increasing in recent years. In this paper, we report a case of VAD on the contralateral side presenting with subarachnoid hemorrhage in the acute stage of cerebral infarction due to unilateral VAD.

Antagonistic activation of AMPA receptors inhibits epilepsy and glioma growth in in vitro and in vivo studies. This study was conducted to evaluate the clinical impacts of perampanel (PER), a novel AMPA receptor antagonist, on seizures and tumor progression in glioma patients with uncontrollable epilepsy.

Background: Stroke-in-evolution (SIE) is a major outcome determinant in patients with acute ischemic stroke. The benefit of surgery for treatment of carotid artery-related SIE remains controversial.
Objective: To retrospectively evaluate the use of carotid artery stenting (CAS) as a possible alternative treatment in patients with carotid-related SIE.
OBJECTIVE The vascular lumen of an acutely occluded internal carotid artery (ICA) generally contains numerous thrombi. Therefore, carotid angiography on the affected side during revascularization therapy of acute ICA occlusion has a potential risk of causing distal embolization. In this study the authors propose the use of contralateral carotid angiography.

Objective: To describe an anchoring technique using a balloon protection device that provides excellent stability of the guiding catheter.
Methods: Four patients (5 stenotic lesions) with stenosis of the CCA origin underwent transfemoral stenting with a balloon protection device (PercuSurge GuardWire; Medtronic, Santa Rosa, California).
The fistulous point in a direct carotid-cavernous fistula (CCF) can often be difficult to identify because of high-flow shunting. A novel technique that is useful for identifying the fistulous point is reported. A 71-year-old woman underwent endovascular therapy for a left direct CCF that presented with sudden diplopia and tinnitus.

The case of a 59-year-old woman who presented with a pulsatile mass on the left side of her neck, was diagnosed with a left-sided giant thrombosed common carotid artery aneurysm, and underwent definitive treatment by overlapped stenting, is presented. Overlapped stenting is a safe and an effective treatment procedure for ECAA.

We recently performed cerebral angiography using a Gd contrast agent in a patient with an anterior condylar confluence dAVF who was allergic to iodine. To our surprise, there was spontaneous closure of the dAVF immediately after angiography.

Objective: Glossopharyngeal neuralgia (GN) is a rare disease often clinically misdiagnosed as trigeminal neuralgia. An endovascular provocative test has been applied to assist in making the diagnosis of GN caused by vascular compression. We similarly used endovascular provocative techniques to identify the causative vessel and to evaluate the indication for microvascular decompression (MVD) in two patients.

Early effects of boron neutron capture therapy (BNCT) on malignant glioma are characterized by reduction of the enhancement area and regression of the peritumoral edema radiologically. The aim of this study was to investigate the early histological changes of tumors and inflammatory cells after BNCT in the rat brain. Rats were treated with BNCT using boronophenylalanine (BPA) 7 days after implantation of C6 glioma cells.
