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.

Cost-Drivers in Acute Treatment of Severe Trauma in Europe: A Systematic Review of Literature.
Throughout the world, trauma is a leading cause of morbidity and mortality in the young and most active group of society. While specialist trauma centers play a critical role in the survival after severe trauma, the assessment of trauma-related costs, budgeting for adequate trauma capacity, and determining the cost-effectiveness of interventions in critical care are fraught with difficulties. Through a systematic review of the European literature on severe trauma, we aimed to identify the key elements that drive the costs of acute trauma care. ⋯ Irrespective of the idiosyncrasies of the national healthcare systems in Europe, severity of injury, length of stay in ICU, surgical interventions and transfusion requirements represent the key drivers of acute trauma care for severe injury.

Emerging research implicates the participation of spinal dorsal horn (SDH) neurons and astrocytes in nerve injury-induced neuropathic pain. However, the crosstalk between spinal astrocytes and neurons in neuropathic pain is not clear. Using a lumbar 5 (L5) spinal nerve ligation (SNL) pain model, we testified our hypothesis that SDH neurons and astrocytes reciprocally regulate each other to maintain the persistent neuropathic pain states. ⋯ Meanwhile, L-AA shortened the duration of neuronal activation by SNL. Our data offers evidence that neuronal and astrocytic activations are closely related with the maintenance of neuropathic pain through a reciprocal "crosstalk". The current study suggests that neuronal and non-neuronal elements should be taken integrally into consideration for nociceptive transmission, and that the intervention of such interaction may offer some novel pain therapeutic strategies.

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.

Diaphragmatic rupture is a life-threatening condition. Diaphragmatic injuries are quite uncommon and often result from either blunt or penetrating trauma. Diaphragmatic ruptures are usually associated with abdominal trauma however, it can occur in isolation. ⋯ We have focussed on mechanism of injury, duration, presentation and site of injury, visceral herniation, investigations and different approaches for repair. We intend to stress on the importance of delay in presentation of diaphragmatic rupture and to provide a review on the available investigations and treatment methods. The enclosed case report also emphasizes on the delayed presentation, diagnostic challenges and the advantages of laparoscopic repair of delayed diaphragmatic rupture.
