Vertebral fractures occur with only slight trauma in patients with diffuse idiopathic skeletal hyperostosis (DISH). However, a lumbar vertebra fracture, due to an intraoperative body position has not been previously reported. An 87-year-old woman with kyphosis sustained a left trochanteric fracture of her femur. The patient was placed in a supine position during the operation. Postoperatively, ...
Study Design Literature review. Objective The aim of this review is to highlight challenges in the development of a comprehensive surgical algorithm to accompany the AOSpine Thoracolumbar Spine Injury Classification System. Methods A narrative review of the relevant spine trauma literature was undertaken with input from the multidisciplinary AOSpine International Trauma Knowledge Forum. Results...
We present a novel channel partitioning and modulation technique for linear time-varying (LTV) channels using adaptive bases of localized complex exponentials. We show that localized complex exponentials are approximate eigenfunctions of underspread LTV channels. A basis of localized complex exponentials that approximately diagonalizes the LTV channel is selected adaptively by the receiver duri...
In the neonate, vertebral ossification is not complete. Hence in the first half of infancy before the spinous processes ossify and fuse, it is possible to image the spinal canal from a dorsal view. Later in life a paramedian approach can be used when the spinous processes are more ossified and lead to posterior acoustic shadowing hence precluding imaging in the midline sagittal plane. A high fr...
We hypothesized that the influence of acute kidney injury (AKI) on the sensitivity of the lung to an injurious process varies with the severity of the injurious process. Thus, we thought that AKI would exacerbate lung injury from low degrees of lung trauma but attenuate lung injury from higher degrees of lung trauma. C57BL/6 mice underwent AKI (30-min kidney ischemia) or sham surgery, followed ...
The Las Tres Vírgenes (LTV) geothermal reservoir is a liquid-dominated resource located in the Baja California Peninsula (NW-Mexico) with a currently installed power capacity of 10 MWe. The sustainability of future electricity production at the LTV geothermal field raises concerns about the origin and hydraulic dynamics of exploited geothermal fluids. As part of the present study, water samples...
