An online tumor board with international neurosurgical collaboration guides surgical decision-making in Western Kenya.

Telecollaboration via web-based platforms has emerged as a tool to relieve constraints on the establishment of tumor boards for neurosurgical oncology. Challenging tumor cases arising in low- and middle-income countries may benefit from the use of such models. The case of a 5-year-old boy presenting in Western Kenya with a challenging tumor and symptomatic hydrocephalus was presented on a novel web platform to a multi-national audience of neurosurgeons.

Clinical outcomes for lumbar fusion using silicon nitride versus other biomaterials.

Background: In lumbar fusion surgery, intervertebral spacer cages made of silicon nitride (SiN) ceramic are an available option among other biomaterials. While the surface chemistry of SiN is known to favor bone fusion, large-scale clinical studies attesting to its efficacy are lacking. This multicenter retrospective study compared lumbar fusion outcomes for SiN cages to previously reported data for other cage materials.

Clinical outcomes for anterior cervical discectomy and fusion with silicon nitride spine cages: a multicenter study.

Background: Intervertebral spacers made of silicon nitride (SiN) are currently used in cervical and thoracolumbar fusion. While basic science data demonstrate several advantages of SiN over other biomaterials, large-scale clinical results on its safety and efficacy are lacking. This multicenter retrospective study examined outcomes for anterior cervical discectomy and fusion (ACDF) using SiN cages.

Treatment of lumbar discitis using silicon nitride spinal spacers: A case series and literature review.

Introduction: Septic infection of a lumbar intervertebral disc is a serious disorder which is often difficult to diagnose and appropriately treat because of the rarity of the disease, the varied presentation of symptoms, and the frequency of low-back pain within the overall population. Its etiology can be pyogenic, granulomatous, fungal, or parasitic; its incidence is rising due to increased patient susceptibility and improved diagnostic tools. Conservative treatments involve antibiotics, physical therapy, and/or immobilization.

The Effect of Prior Information on Attitude Change.

An 18 month longitudinal study tested the assumption that the amount of prior political information influences the degree of ideological attitude change under conditions of exposure to counterattitudinal presentations. Male and female college students (n = 97) served as Ss, and the study was conceived as a natural experiment in which the attitudes of beginning freshmen were exposed to the questioning and challenge of college coursework. Results indicated that well and moderately informed students changed their political orientation less than poorly informed students.

Some Correlates of the Level of Constraint in a System of Social Attitudes.

Variables thought to be associated with the magnitude of interrelationship observed among the elements in a system of social attitudes were investigated. Subjects (N = 753) were asked to respond to an inventory requesting self-report and background data. Several weeks later, Ss were given two forms of the Social Attitude Scale, a scale tapping the liberalism-conservatism domain.
