Real-time in vivo assessment of the nerve microenvironment with coherent anti-Stokes Raman scattering microscopy.
Current analysis of nerve injury and repair relies largely on electrophysiologic and ex vivo histologic techniques. In vivo architectural assessment of a nerve without removal or destruction of the tissue would greatly assist in the grading of nerve injury and in the monitoring of nerve regeneration over time. Coherent anti-Stokes Raman scattering microscopy is an optical process with particular sensitivity for high-lipid-containing molecules such as myelin. This in vivo nonthermal technique offers high-resolution images that the authors aim to evaluate in both normal and injured nerves. ⋯ The authors conclude that coherent anti-Stokes Raman scattering microscopy has the ability to image the peripheral nerve following demyelinating crush injury. This technology, which permits in vivo, real-time microscopy of nerves at a resolution of 5 mum, could provide invaluable diagnostic and prognostic information regarding intraneural preservation and recovery following injury.

Hemorrhage is More Prevalent than Brain Injury in Early Trauma Deaths: The Golden Six Hours.
Under the trimodal distribution, most trauma deaths occur within the first hour. Determination of cause of death without autopsy review is inaccurate. The goal of this study is to determine cause of death, in hourly intervals, in trauma patients who died in the first 24 h, as determined by autopsy. ⋯ The temporal distribution of the cause of death varies in the first 24 h after admission. Hemorrhage should not be overlooked as the cause of death, even after survival beyond 1 h. Understanding the temporal relationship of causes of early death can aid in the targeting of management and surgical training to optimize patient outcome.

ReviewGlycemia management in neurocritical care patients: a review.
Intensive research investigating the relation between the management of glycemia and outcome in patients receiving neurocritical care has underlined the possible benefits and adverse events related to glucose control. Here, we review experimental and clinical studies investigating the effects of hypoglycemia and hyperglycemia on the brain that advance current knowledge on managing glycemia in patients receiving neurocritical care.

ReviewFrom the battlefront: peripheral nerve surgery in modern day warfare.
Warfare historically causes a large number of peripheral nerve injuries. During the current global war on terror, an increased use of advanced regional anesthesia techniques appears to have significantly reduced pain syndromes that have been previously reported with missile-induced nerve injuries. Additionally, a new program has been established to develop advanced prosthetic devises that can interface with neural tissue to obtain direct neural control. As this technology matures, the functional restoration gained from these new generation prosthetic devices may exceed that which can be obtained by standard nerve repair techniques.

To evaluate the outcomes of early comprehensive rehabilitation protocols for traumatic brain injury (TBI) using the functional independence measure (FIM), and to study the relationship between FIM and Glasgow coma scale (GCS) variables to determine which patients will be best served by rehabilitation therapies. ⋯ Early rehabilitation interventions significantly improved the FIM scores in moderate and severe TBI patients.
