Correlation of supine MRI and standing radiographs for cervical sagittal balance in myelopathy patients: a cross-sectional study.

Purpose: Cervical sagittal alignment is correlated with myelopathy severity and used by spinal surgeons for surgical planification. Magnetic resonance imaging (MRI) is the gold standard for the evaluation of cervical myelopathy but may not be for the assessment of cervical sagittal balance compared to X-rays. The objective of this study was to assess the correlation of cervical alignment between supine MRI and standing radiographs in patients with cervical spondylotic myelopathy (CSM).

A Randomized Controlled Trial Comparing Learners' Decision-making, Anxiety, and Task Load During a Simulated Airway Crisis Using Two Difficult Airway Aids.

Introduction: The American Society of Anesthesiologists (ASA) difficult airway algorithm and the Vortex approach are difficult airway aids. Our objective was to demonstrate that a simpler cognitive model would facilitate improved decision-making during a process such as difficult airway management. We hypothesized the simpler Vortex approach would be associated with less anxiety and task load.

Preoperative magnetic resonance imaging is associated with baseline neurological status and can predict postoperative recovery in patients with cervical spondylotic myelopathy.

Study Design: A blinded observational study of consecutive patients, prospectively enrolled and followed up to 1 year postoperatively.

Objective: To assess whether quantitative assessment of preoperative magnetic resonance imaging (MRI) predicts baseline patient status and postoperative neurological recovery.

Summary Of Background Data: Factors that can predict neurological recovery in patients with cervical spondylotic myelopathy (CSM) postoperatively are of great interest.

Transcriptomic analysis of human retinal detachment reveals both inflammatory response and photoreceptor death.

Background: Retinal detachment often leads to a severe and permanent loss of vision and its therapeutic management remains to this day exclusively surgical. We have used surgical specimens to perform a differential analysis of the transcriptome of human retinal tissues following detachment in order to identify new potential pharmacological targets that could be used in combination with surgery to further improve final outcome.

Methodology/principal Findings: Statistical analysis reveals major involvement of the immune response in the disease.

Postoperative magnetic resonance imaging can predict neurological recovery after surgery for cervical spondylotic myelopathy: a prospective study with blinded assessments.

Background: Factors that can predict the recovery of cervical spondylotic myelopathy (CSM) patients postoperatively are of significant interest to physicians and patients and their families. Magnetic resonance imaging (MRI) scans are a common method of examination after surgery, and thus of interest as a predictor of outcome.

Objective: To investigate whether findings on MRI at 6 months postoperatively could predict recovery at 1 year in CSM patients.

The delta envelope: a technique for dose distribution comparison.

The gamma index is a tool that compares a dose distribution with a reference distribution by combining dose-difference and distance-to-agreement criteria. It has been widely used for ten years despite its high computational cost. This cost is due to both a search process for each reference point and the necessity to remove overestimations caused by the discrete nature of dose grids.
