Ways of Reasoning Used by Nurses in Postoperative Pain Assessment.

Background: Postoperative pain is a major concern of patients undergoing surgery. Pain assessment for patients undergoing surgery is a common requirement for surgical nurses and is the most important nursing approach to ensuring patient comfort.

Aims: The purpose of this study was to identify the reasoning used by nurses when assessing postoperative pain in patients.

Seed-Based Resting-State Functional MRI for Presurgical Localization of the Motor Cortex: A Task-Based Functional MRI-Determined Seed Versus an Anatomy-Determined Seed.

Objective: For localization of the motor cortex, seed-based resting-state functional MRI (rsfMRI) uses the contralateral motor cortex as a seed. However, research has shown that the location of the motor cortex could differ according to anatomical variations. The purpose of this study was to compare the results of rsfMRI using two seeds: a template seed (the anatomically expected location of the contralateral motor cortex) and a functional seed (the actual location of the contralateral motor cortex determined by task-based functional MRI [tbfMRI]).

Differentiation of grade II and III oligodendrogliomas from grade II and III astrocytomas: a histogram analysis of perfusion parameters derived from dynamic contrast-enhanced (DCE) and dynamic susceptibility contrast (DSC) MRI.

Background Since oligodendroglial tumors are sensitive to chemotherapy and have a better prognosis, the differentiation of oligodendroglial tumors (OT) from astrocytic tumors (AT) is important. Purpose To investigate the perfusion and permeability parameters that differentiate grade II and III OT from AT, using dynamic contrast-enhanced (DCE) and dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI). Material and Methods We retrospectively reviewed the DCE and DSC MRIs of 39 patients with OT (OTs, n = 19; grade II, n = 12 and grade III, n = 7) and AT (ATs, n = 20; grade II, n = 7 and grade III, n = 13).

Differential diagnosis of oligodendroglial and astrocytic tumors using imaging results: the added value of perfusion MR imaging.

Purpose: The purposes of the present study are to assess whether different characteristics of oligodendrogliomas and astrocytic tumors are visible on MR imaging and to determine the added value of perfusion imaging in conventional MR imaging when differentiating oligodendrogliomas from astrocytic tumors.

Methods: We retrospectively studied 22 oligodendroglioma and 54 astrocytic tumor patients, including glioblastoma multiforme (GBM). The morphological tumor characteristics were evaluated using MR imaging.

Asymmetric synthesis of α-alkylidene-β-hydroxy-γ-butyrolactones via enantioselective tandem Michael-aldol reaction.

A simple and efficient method for the asymmetric synthesis of α-alkylidene-β-hydroxy-γ-butyrolactones and related natural products was developed on the basis of the catalytic asymmetric tandem Michael-aldol reaction and simple transformations. The synthetic utility of this method was illustrated by the facile synthesis of trisubstituted γ-butyrolactone natural products.

Evaluation of middle cerebral artery stents using multidetector row CT angiography in vivo study: comparison of the three different kernels.

Background: There are very few reports assessing middle cerebral artery (MCA) stents using multidetector computed tomography (MDCT).

Purpose: To assess MCA stents using multidetector CT angiography (CTA) in vivo evaluation: the differences in the CTA results according to the three different kernels.

Material And Methods: We retrospectively evaluated 27 MCA stents from 26 patients who underwent CTA with 16- and 64-slice MDCT after percutaneous transluminal angioplasty and stenting (PTAS).

High-intensity focused ultrasound ablation in hepatic and pancreatic cancer: complications.

Purpose: To evaluate the complications of high-intensity focused ultrasound (HIFU) in patients with hepatic and pancreatic cancer.

Materials And Methods: From January 2006 to December 2008, 133 sessions of HIFU treatment were performed in 114 consecutive patients with primary hepatic tumor (n = 57), hepatic metastasis (n = 22), and pancreatic cancer (n = 35) under general anesthesia. The extracorporeal, ultrasound-guided Model-JC system (HAIFU, Chongqing, China) was used.

Small bowel volvulus induced by mesenteric lymphangioma in an adult: a case report.

Mesenteric lymphangiomas are rare abdominal masses that are seldom associated with small bowel volvulus, and especially in adult patients. We report here on an unusual case of small bowel volvulus that was induced by a mesenteric lymphangioma in a 43-year-old man who suffered from repeated bouts of abdominal pain. At multidetector CT, we noticed whirling of the cystic mesenteric mass and the adjacent small bowel around the superior mesenteric artery.
