Purpose: Mammalian central nervous system axons fail to regenerate after injury. Contributing factors include limited intrinsic growth capacity and an inhibitory glial environment. Inflammation-induced optic nerve regeneration (IIR) is thought to boost retinal ganglion cell (RGC) intrinsic growth capacity through progrowth gene expression, but effects on the inhibitory glial environment of the optic nerve are unexplored. To investigate progrowth molecular changes associated with reactive gliosis during IIR, we developed an imaging mass spectrometry (IMS)-based approach that identifies discriminant molecular signals in and around optic nerve crush (ONC) sites...

In the present study, the effects of hyaluronic acid (HA) combined with chitosan conduit on peripheral nerve scarring and regeneration were investigated in a rat model of peripheral nerve crush injury. A total of 60 Sprague-Dawley rats were randomly distributed into four groups (15 rats in each group), in which the nerve was either not treated (control group) or treated with chitosan conduit, hyaluronic acid, or chitosan conduit coupled with hyaluronic acid following clamp injury to the sciatic nerve. The surgical sites were evaluated by assessing the sciatic functional index, the degree of scar adhesions, the numbers of myelinated nerve fibers, the average diameter of myelinated nerve fibers and the myelin sheath thickness...

Rhabdomyolysis is a serious syndrome caused by skeletal muscle injury and the subsequent release of breakdown products from damaged muscle cells into systemic circulation. The muscle damage most often results from strenuous exercise, muscle hypoxia, medications, or drug abuse and can lead to life-threatening complications, such as acute kidney injury (AKI). Rhabdomyolysis and the AKI complication can also occur during crush syndrome, an emergency condition that commonly occurs in victims of natural disasters, such as earthquakes, and man-made disasters, such as wars and terrorism...

William R VanWye, Donald L Hoover
BACKGROUND AND PURPOSE: Qualitative analysis has its limitations as the speed of human movement often occurs more quickly than can be comprehended. Digital video allows for frame-by-frame analysis, and therefore likely more effective interventions for gait dysfunction. Although the use of digital video outside laboratory settings, just a decade ago, was challenging due to cost and time constraints, rapid use of smartphones and software applications has made this technology much more practical for clinical usage...

Introduction: Rhabdomyolysis (RM) is a condition where there is injury to striated muscle fibers causing release of myoglobin, creatine phosphokinase (CPK), and other intracellular contents into the circulation. High myoglobin levels cause acute kidney injury (AKI). Trauma is the most common cause of RM and development of complications related to the degree of myoglobin released. Currently, the degree of RM is assessed and treatment is instituted based on serum CPK. As myoglobin is the direct cause of AKI, we set out to determine if serum myoglobin is a more reliable predictor than CPK for the development of AKI in traumatic RM...

The delivery of a nerve insult (a "conditioning lesion") prior to a subsequent test lesion increases the number of regenerating axons and accelerates the speed of regeneration from the test site. A major barrier to clinical translation is the lack of an ethically acceptable and clinically feasible method of conditioning that does not further damage the nerve. Conditioning electrical stimulation (CES), a non-injurious intervention, has previously been shown to improve neurite outgrowth in vitro. In this study, we examined whether CES upregulates regeneration-associated gene (RAG) expression and promotes nerve regeneration in vivo, similar to a traditional nerve crush conditioning lesion (CCL)...

CASE: We present a case of delayed osteonecrosis of the ilium. After receiving embolization and multiple orthopaedic procedures following a complex pelvic crush injury, the patient subsequently developed posterior pelvic pain and tenderness over the posterior superior iliac spine, along with pain on sacroiliac joint compression. Magnetic resonance imaging of the pelvis demonstrated a bone infarction in the left ilium adjacent to the sacroiliac joint. CONCLUSION: The symptoms from osteonecrosis of the ilium may simulate sacroiliitis or other conditions...

To explore the hypothesis that CD200Fc, a CD200R1 agonist with anti-inflammatory properties, will inhibit retinal glial cells hyperactivation and retinal ganglion cells (RGCs) apoptosis after optic nerve injury. CD200Fc was immediately administered after optic nerve crush (ONC) once by intravitreal injection. Rats were euthanized at 5 days after ONC. The density of RGCs was counted by immunostaining of retina flat mounts for Brn3a. TUNEL assay, immunoblotting analysis of ionized calcium-binding adapter molecule 1(iba1) (microglia marker) and glial fibrillary acidic protein (GFAP) (astrocytes and Müller cells marker), RT-PCR analysis of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), monocyte chemotactic protein 1 (MCP-1), tumor necrosis factor-α (TNF-α), interleukin (IL)-8 and IL-10, ELISA measure protein levels of inflammatory cytokines and western blot analysis of CD200 and CD200R1 were evaluated...

BACKGROUND: Valproic acid (VPA) is a histone deacetylase inhibitor that improves outcomes in large animal models of trauma. However, its protective mechanism of action is not completely understood. We sought to characterize the genetic changes induced by VPA treatment following traumatic injuries. METHODS: Six female Yorkshire swine were subjected to traumatic brain injury (TBI, controlled cortical impact), polytrauma (liver and splenic laceration, rib fracture, rectus crush), and hemorrhagic shock (HS, 40% total blood volume)...

Although training programs with regular eccentric (ECC) exercise are more commonly used for improving muscular strength and mobility, ECC exercise effects upon functional recovery of the sciatic nerve has not yet been determined. After sciatic nerve crush, different mice groups were subjected to run on the treadmill for 30 min at a speed of 6, 10, or 14 m/min with - 16° slope, 5 days per week, over 8 weeks. During the training time, neuropathic pain-like behavior (mechanical and cold hyperalgesia) was assessed and functional recovery was determined with the grip strength test and the Sciatic Functional and Static indexes (SFI and SSI)...

RATIONALE: Occupational burn injuries can be detrimental and difficult to manage. The majority of complex cases are referred and managed at regional burn centers where access to specialized care is available. As an alternative to hospitalization with staged surgical procedures, placental products may be used for outpatient medical management of these common burn injuries, especially if access to a regional burn center is limited or restricted.Fresh amnion has been a treatment of choice in burns for more than 100 years...

Introduction: Impalement injuries of pelvis have been reported in children but are uncommon. Impalement could be associated with injuries to deep organs, wound contamination, crush injuries, and in certain instances, can even be fatal. Case Report: We present a bizarre case of a 2-year-old female child who presented to us with a tapestry needle embedded in the true pelvic cavity after a history of fall on the buttock while playing at home. The impaled needle was eventually successfully extracted surgically using the modified Stoppa's approach and the post-operative period was uneventful...

The lack of axonal regeneration and neuronal cell death causes permanent neurological deficits in the injured CNS. Using the classical CNS injury model of optic nerve crush in mice, ciliary neurotrophic factor (CNTF) was found to stimulate retinal ganglion cell (RGC) survival and axonal growth, but in an incomplete fashion. The elucidation of molecular mechanisms impairing CNTF-induced axonal regeneration is paramount to promote visual recovery. In the present study, we sought to evaluate the contribution of sphingosine 1-phosphate receptor 1 (S1PR1) to the neuroprotective and regenerative effects of CNTF...

The progress of axonal degeneration (AxD) following injury or insult impacts both recovery from axonal transection and protection of axons from diverse insults, or axonopathy. Here we provide evidence that increases in capase-6 (Casp6) expression and action contribute to the progression of AxD. The expression of Casp6 protein and mRNA in distal branches of sensory axons undergoing AxD was confirmed. We developed and utilized a new model of axonopathy in live mice by serially visualizing the viability of cutaneous axons in the ear pinna that expressed an axonal YFP transgene, in response to capasaicin-induced AxD...
