Traumatic injury to the posterior fossa: a secondary analysis and description of case series from the NEXUS head injury dataset.

Background: Traumatic brain injuries involving the posterior fossa are rare and case reports indicate they often result in severe outcomes. We seek to describe characteristics and outcomes of traumatic posterior fossa injuries.

Methods: We performed a planned secondary analysis of all patients with posterior fossa injuries enrolled in the NEXUS head computed tomography (CT) validation study dataset.

Cataract Surgical Planning Using Online Software vs Traditional Methods: A Time/Motion and Quality of Care Study.

Purpose: The objective of this study is to compare two methods of preoperative planning for placement of intraocular implants: traditional paper documentation/electronic scans versus a novel online planning software. The aim was to compare the time required and number of data points manually transcribed with each method and to explore whether differences in surgical accuracy could be identified between the two methods in a small sample of 40 patients.

Methods: In this study, preoperative planning was performed twice for all enrolled patients: once through the traditional method and once using an online planning software system.
