A new test for diagnosing vasovagal syncope: Standing after treadmill test with sublingual nitrate administration.

Introduction: Increased adrenergic tone might be an additional trigger of orthostatic stress of vasovagal syncope (VVS). Exercise before standing might provide increased sensitivity compared to standing using a sublingual nitroglycerines protocol during tilt table testing. The aim of this study was to evaluate the diagnostic value of treadmill testing before standing with nitroglycerin administration.

What Should Be Considered to Cause the Early Post-Craniotomy Seizure: Antibiotics (Cefazolin) Irrigation.

Objective: Post-craniotomy seizure (PCS) is reported only rarely. However, our department noted a 433% increase in PCS for a year beginning September 2010, especially after cerebrovascular surgery. Our goal was to identify the cause of our unusual outbreak of PCS.

Early carotid artery stenting for symptomatic carotid artery stenosis.

Background: The aim of present study was to assess safety and efficacy of early carotid artery stent (CAS) in patients with symptomatic carotid artery stenosis compared with delayed CAS.

Methods: This retrospective study was approved by the institutional review board, and the requirement to obtain written informed consent was waived. Outcomes of 206 patients with symptomatic carotid stenosis who were treated by CAS were analyzed.

Delayed ischemic stroke after stent-assisted coil placement in cerebral aneurysm: characteristics and optimal duration of preventative dual antiplatelet therapy.

Purpose: To evaluate characteristics of delayed ischemic stroke after stent-assisted coil placement in cerebral aneurysms and to determine the optimal duration of dual antiplatelet therapy for its prevention.

Materials And Methods: This retrospective study was approved by the institutional review board, and the requirement to obtain written informed consent was waived. Of 1579 patients with 1661 aneurysms, 395 patients (25.

Surgical flow disconnection of cerebral pial dual-channel arteriovenous fistula with a large varix: the role of anti-platelet agent or anti-coagulation therapy.

Introduction: Intracranial pial arteriovenous fistula (AVF) is a rare cerebrovascular lesion, and the literature is sparse. Most authors insist that simple disconnection of arteriovenous shunting is enough to treat intracral single-channel pial AVF in most cases, either by microsurgery or endovascular embolization without resection of entire vascular malformation.

Discussion: We report an insidious onset of peri-lesional edema formation after abrupt disconnection of AVF shunting with surgical arterial ligation.

Emergency In Situ Bypass during Middle Cerebral Artery Aneurysm Surgery: Middle Cerebral Artery-Superficial Temporal Artery Interposition Graft-Middle Cerebral Artery Anastomosis.

Many reports have been published on complications related to middle cerebral artery (MCA) aneurysm surgical clipping procedures. We report an emergency intracranial in situ bypass surgery case which was performed as a rescue procedure after aneurysmal neck laceration during clipping of an MCA large aneurysm. In this case, we performed in situ M3-superficial temporal artery (STA) interposition graft-M3 bypass procedure.

Effects of sodium laurylsulfate on crystal structure of calcite formed from mixed solutions.

Sodium laurylsulfate (SLS), an anionic surfactant, was used for tailoring calcite via a solution route. SLS was dissolved in calcium and carbonate source solutions at various concentrations and critical micelle concentrations (CMCs). The crystallized particles were characterized using X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), laser-scattering particle size measurements, and thermogravimetric analysis (TGA).

Long-term outcomes in children with glioblastoma.

Object: Glioblastoma is the most common primary malignant brain tumor; however, glioblastoma in children is less common than in adults, and little is known about its clinical outcome in children. The authors evaluated the long-term outcome of glioblastoma in children.

Methods: Twenty-seven children were confirmed to have harbored a glioblastoma between 1985 and 2007.

Third ventricular chordoid meningioma in a child.

Meningiomas are rare in children. Chordoid meningioma is a very rare variant, as only 16 cases in children have been reported. The authors report the first case of a chordoid meningioma in the third ventricle.
