To analyze the impact of factors known after admission on mortality attributable to aneurysmal subarachnoid hemorrhage (SAH) resulting from saccular intracranial aneurysm (IA). ⋯ Sequelae of aneurysmal SAH were the leading cause of death for 12 months. Mortality analysis of this period displayed three phases with distinct independent risk factors. These data support the creation of prognosticators for prediction on admission of the everyday individual risk of death until 12 months after aneurysmal SAH.

The use of nanoparticles in diagnostic imaging is rapidly gaining utility and acceptance. A handful of iron oxide nanoparticle compounds have already been approved by the U. S. ⋯ The ability of these particles to interact with cellular biology at a molecular level does have theoretical injurious potential. As with any medical intervention, its relative risks must be clearly understood. This article discusses the safety profile and potential toxicities of nanoparticles as used in diagnostic imaging, and serves to inform the prescribing physician of relative and potential risk to the patient.

Percutaneous trans-facet screws for supplemental posterior cervical fixation.
Numerous innovative minimally invasive fusion and fixation techniques for the thoracolumbar spine have recently been developed. However, less-invasive approaches for accessing the posterior cervical spine surgery have been more elusive. One promising option for posterior cervical fixation is trans-facet screw placement. ⋯ In this report we describe an initial clinical experience with cervical trans-facet screws, which we found to be a technically feasible option in the subaxial cervical spine for truly percutaneous spinal fixation. However, until percutaneous bony fusion methods are developed, this approach is limited to the fixation application, such as supplementing an anterior fusion construct.
