With an increasing life expectancy and more active elderly population, management of geriatric trauma patients continues to evolve. The aim was to describe the mechanism and injuries of severely injured geriatric patients and to identify risk factors associated with mortality. ⋯ Falls continue to be the most frequent mechanism of injury in severely injured geriatric patients. Risk factors associated with a higher likelihood of death are identified. More research is needed to better understand this important and increasing group of trauma patients.

Apnea (APN) and pneumothorax (PTX) are common immediately life-threatening conditions. Ultrasound is a portable tool that captures anatomy and physiology as digital information allowing it to be readily transferred by electronic means. Both APN and PTX are simply ruled out by visualizing respiratory motion at the visceral-parietal pleural interface known as lung sliding (LS), corroborated by either the M-mode or color-power Doppler depiction of LS. We thus assessed how economically and practically this information could be obtained remotely over a cellular network. ⋯ The emergent exclusion of APN-PTX can be immediately accomplished by a remote expert economically linked to almost any responder over cellular networks. Further work should explore the range of other physiologic functions and anatomy that could be so remotely assessed.

Neurological, functional, and biomechanical characteristics after high-velocity behind armor blunt trauma of the spine.
Behind armor blunt trauma (BABT) describes a nonpenetrating injury to the organs of an individual wearing body armor. The aim of this study was to investigate the neurologic and functional changes that occur in the central nervous system after high-velocity BABT of the spine as well as its biomechanical characteristics. ⋯ The results from our animal model indicate that high-velocity BABT of the spine generates high pressure and acceleration in the spine, induces varying degrees of paralysis of hind limbs, and disturbs cerebral function. The neuronal degeneration caused by the pressure wave may be one of the important pathologic events involved in the development of trauma-related complications.

Elevated admission systolic blood pressure after blunt trauma predicts delayed pneumonia and mortality.
Although avoiding hypotension is a primary focus after trauma, elevated systolic blood pressure (SBP) is frequently disregarded. The purpose of this study was to determine the association between elevated admission SBP and delayed outcomes after trauma. ⋯ In blunt trauma patients with or without TBI, elevated admission SBP was associated with worse delayed outcomes. Prospective research is necessary to determine whether algorithms that manage elevated blood pressure after trauma, especially after TBI, affect mortality or pneumonia.

Comparative Study
Utility of repeat head computed tomography in patients with an abnormal neurologic examination after minimal head injury.
Previous studies proposed that repeat head computed tomography (RHCT) is of no value in patients with a minimal head injury (MHI) and normal neurologic examination (NE). The goal of our study was to investigate the value of RHCT in patients with MHI with an abnormal NE. ⋯ Of all patients with MHI with an abnormal NE at the time of RHCT, 63% had a PA-NE. Although a RHCT is beneficial to patients with an acutely deteriorating or U-NE, it appears to be of little value in patients with a PA-NE. Compared with RHCT, serial NE may be a stronger predictor for the need for intervention in patients with MHI.
