OBJECTIVE Dexmedetomidine is known to reduce the incidence of emergence agitation, which is a common complication after inhalational anesthesia like sevoflurane or desflurane in children. However, the dose of dexmedetomidine used for this purpose is reported variously and the most effective dose is not known. In this study, we tried to find the most(More)
The purpose of this study was to compare the fracture resistance of copy-milled and conventional In-Ceram crowns. Four groups of 10 uniform sized all-ceramic anterior crowns were fabricated for this test: (1) In-Ceram Spinell (2) In-Ceram Alumina (3) Celay In-Ceram Spinell, and (4) Celay In-Ceram Alumina crowns. All specimens were cemented on stainless(More)
— The pulsatile motion artifacts in the radial spin-echo diffusion-weighted-imaging (rSE-DWI) are analyzed and a method to improve the image quality of the rSE-DWI using the projection data regeneration method is proposed in this work. In general, ECG-triggering is used together with the rSE-DWI in order to prevent the loss of projection data, where the(More)
A voxel based investigation of cerebral blood flow was conducted to identify brain functional differences during resting state between children with developmental language disorder (DLD) and normal controls. Using DSM–IV criteria, we selected 21 children with DLD. All children were examined by technetium–99m–HMPAO Brain SPECT. Using SPM analyses, we(More)
Editor's key points † Moyamoya is a disease characterized by intimal thickening of the terminal internal carotid arteries. † In children, symptoms are caused by ischaemia, whereas in adults, most neurological signs result from haemorrhage. † Among 82 patients with Moyamoya undergoing extracranial to intracranial anastomoses, 29 suffered symptomatic cerebral(More)
