Convection-enhanced delivery (CED) is a novel intracerebral drug technique with considerable promise for delivering therapeutic agents throughout the CNS. Despite this promise, Phase III clinical trials employing CED have failed to meet end points. Although may be due inactive or failure rigorously validate targets, authors previously demonstrated that catheter positioning plays major role in distribution using technique. The purpose of present work was retrospectively analyze expected based...

Object Choroid plexus tumors (CPTs) are rare intracranial neoplasms that constitute approximately 2%–5% of all pediatric brain tumors. Most these present with severe hydrocephalus. The optimal perioperative management and oncological care remain a matter debate. authors the epidemiological clinical features CPTs from 20-year single-institutional experience. Methods A total 39 consecutive patients pathologically proven (31 choroid papillomas [CPPs] 8 carcinomas [CPCs]) were included in this...

To understand the role of N-acetylaspartate (NAA) as an acetyl donor, we investigated metabolism NAA in brain and liver slice preparations. The tissue slices were incubated with [14C-acetyl]NAA (SA = 3 μCi/μmol) or [14C]acetate for 2 h. was homogenized extracted using chloroform/methanol (2:1). aqueous phase initially analyzed anion exchange HPLC while lipid a two-dimensional TLC system. Further resolution peak from performed reverse both samples revealed similar patterns three distinct...

Background: The Institute of Medicine calls for the use clinical guidelines and practice parameters to promote "best practices" improve patient outcomes. In 2006, Trauma Association Canada Pediatric Committee set out create an evidence-based, national pediatric cervical spine (c-spine) clearance guideline based on literature, existing algorithms from each trauma center expert opinion across Canada. Methods: A review literature took place in September 2006 using PubMed database. Search...

Object Tethered cord syndrome (TCS) is frequently associated with scoliosis in the pediatric population. Following spinal untethering, many patients continue to experience progression of deformity. However, incidence rate, time course, and risk factors for following tethered release remain unclear. The aim this study was determine whether alone would halt curve TCS. Methods authors retrospectively reviewed 27 consecutive cases untethering scoliosis. rate (> 10° increased Cobb angle) after...

IntroductionTo maximize the benefits of computed tomographic screening for lung cancer, optimal treatment small, early cancers is needed. Limiting extent surgery spares tissue, preserves pulmonary function, and decreases operative time, complications, morbidities. It also increases likelihood resecting future new primary cancers. The goal to assess alternative treatments in a timely manner.MethodsThe focus sessions with patients physicians separately highlighted need consider their...

The radiographic identification of pineal cysts has increased dramatically within the last two decades due to advent magnetic resonance imaging. Pineal are often found incidentally with only a minority these lesions ever becoming symptomatic and requiring treatment. Many theories attempting explain pathogenesis exist.We describe case 12-year-old girl who presents hemorrhage unknown etiology associated hydrocephalus.Her hydrocephalus was initially treated an external ventricular drain...

Abstract Background Acute Pain Services (APS) were introduced primarily to improve postoperative pain management. Although is similar in prevalence and severity medical surgical wards, its assessment management non-surgical patients often receives less attention resources. Objective To investigate the extent of APS involvement on wards obtain perceptions deficiencies. Method A questionnaire was mailed leads 287 UK NHS hospitals; 229 questionnaires returned (79.8% response). Results Only 36...
