Correlation Between Visual Acuity and Foveal Threshold by Automated Perimetry With Size V Stimulus.

Background: Visual acuity has been shown to correlate with foveal threshold as determined by automated perimetry. Although automated perimetry with size V stimulus is commonly used in neuro-ophthalmology practice, the relationship between the visual acuity and the foveal threshold with this larger stimulus is not well known.

Methods: Retrospective study of patients who had undergone neuro-ophthalmology evaluation and visual field testing with automated perimetry using size V stimulus.

Neuro-Ophthalmic Features of Autoimmune Encephalitides.

Background: Over the past decade, there has been a remarkable advancement in the understanding of autoimmune etiologies of encephalitis. The first identified generation of paraneoplastic encephalitis tends to occur in older populations, responds poorly to immunotherapy, and is mediated by T-cell damage with antibodies directed toward intracellular antigens. A new generation of autoimmune encephalitides has been described, which are mediated by antibodies to cell-surface proteins, tend to occur in younger individuals, are less frequently associated with malignancy, and often respond better to treatment compared to their intracellular antigen-related paraneoplastic counterparts.

Migraine Headache: Updates and Future Developments.

Migraine is a common disabling condition that is frequently managed by primary care providers. In recent years, the growing array of migraine therapies has added complexity to patient care. This article serves as a succinct review of pertinent updates and future directions regarding migraine.

Outcomes of Surgical Decompression in Patients With Very Severe Degenerative Cervical Myelopathy.

Study Design: A prospective observational international study.

Objective: The aim of this study was to evaluate outcomes of decompressive surgery in patients with very severe degenerative cervical myelopathy (DCM).

Summary Of Background Data: Although decompressive surgery has been evidenced as a safe and effective approach for patients with myelopathic deficiencies, studies have suggested residual disability following treatment in patients with more severe disease presentation.

Psychometric properties of the 30-m walking test in patients with degenerative cervical myelopathy: results from two prospective multicenter cohort studies.

Background Context: The timed 30-m walking test (30MWT) is used in clinical practice and in research to objectively quantify gait impairment. The psychometric properties of 30MWT have not yet been rigorously evaluated.

Purpose: This study aimed to determine test-retest reliability, divergent and convergent validity, and responsiveness to change of the 30MWT in patients with degenerative cervical myelopathy (DCM).

Grade 1 spondylolisthesis and interspinous device placement: removal in six patients and analysis of current data.

Background: In the treatment of patients with Grade 1 spondylolisthesis, the use of interspinous devices has been controversial for nearly a decade. Several authors have suggested that Grade 1 spondylolisthesis be considered a contraindication for interspinous device placement.

Methods: We removed interspinous devices in six symptomatic Grade 1 spondylolisthesis patients and analyzed pertinent literature.

Simulation and resident education in spinal neurosurgery.

Background: A host of factors have contributed to the increasing use of simulation in neurosurgical resident education. Although the number of simulation-related publications has increased exponentially over the past two decades, no studies have specifically examined the role of simulation in resident education in spinal neurosurgery.

Methods: We performed a structured search of several databases to identify articles detailing the use of simulation in spinal neurosurgery education in an attempt to catalogue potential applications for its use.
