In the brain, pressure-induced myogenic constriction of cerebral arteriolar muscle contributes to autoregulation blood flow (CBF). This study examined role 20-HETE in CBF anesthetized rats. The expression P-450 4A protein and mRNA was localized isolated rat by immunocytochemistry situ hybridization. results reverse transcriptase-polymerase chain reaction studies revealed that microvessels express cytochrome 4A1, 4A2, 4A3, 4A8 isoforms, some which catalyze formation from arachidonic acid....
Abstract Background The purpose of this study was to present our evaluation the outcome oropharyngeal cancer managed with neoadjuvant chemotherapy and transoral surgery (TOS) neck dissection as definitive treatment. Methods This is a case series 17 patients advanced who were treated followed by TOS. treatment details oncologic are reported. volumetric response tumor evaluated validated histopathology. Results Seventeen TNM stages III IV constitute for survival analysis. On median mean...
Web-based learning (WBL) modules are effectively used to improve medical education curriculum; however, they have not been evaluated head computed tomography (CT) scan interpretation in an emergency medicine (EM) setting.To evaluate the effectiveness of a WBL module aid identification cranial structures on CT and ability distinguish between normal abnormal findings.Prospective, before-and-after trial Emergency Department academic center. Baseline knowledge was assessed via standardized test...
Objective This study was aimed to determine the utility of quantitative dynamic contrast-enhanced magnetic resonance imaging (MRI) in differentiating benign and malignant lesions patients with known thyroid gland scheduled for resection. Methods Patients resection a mass were prospectively enrolled. Dynamic MRI scans neck performed before surgery. After resection, divided into groups. Quantitative semiquantitative kinetic measurements compared analyzed. Results Twelve 9 identified 19...
Objectives Idiopathic intracranial hypertension (IIH) is a disease defined by elevated pressure (ICP) without an established etiology. Arachnoid granulations (AG) are conduits for CSF resorption from the subarachnoid space to venous system. AG have been implicated play central role in maintaining homeostasis. We tested hypothesis that patients with fewer visible on MRI more likely present IIH. Methods In this institutional review board (Institutional Review Board)-approved retrospective...
An elderly female with progressive proptosis was found to have an aggressive retrobulbar solid orbital mass. The mass distinct from the optic nerve sheath and intracranial meninges, produced concave erosion of sphenoid wing. Operative findings demonstrated adherent dura superior fissure. did not demonstrate meningeal violation, infiltrate fissure, or display spread. remained intact after gross total resection. Histopathology revealed a malignant meningioma papillary focal rhabdoid morphology...

This topic is presented in 2 parts. Part I focuses on facet arthropathy, infection, inflammation, and tumors of the posterior elements. II, volume 36, number 12, will concentrate spondylolysis, spondylolisthesis, other neural arch defects. The spinal elements are a common, yet often overlooked, source neck back pain. include pedicles, articulate processes, joints, laminae, transverse spinous along with ligamentum flavum interconnecting ligaments. Familiarity anatomy diverse pathology...
