Traumatic brain injury (TBI) is a major health and socio-economic problem, but no pharmacological agent is currently approved for the treatment of acute TBI. Thus, there is a great need for advances in this field. Here, we describe a short peptide (sequence CAQK) identified by in vivo phage display screening in mice with acute brain injury. The CAQK peptide selectively binds to injured mouse and human brain, and systemically injected CAQK specifically homes to sites of brain injury in mouse models. The CAQK target is a proteoglycan complex upregulated in brain injuries...

Many procedures in modern clinical medicine rely on the use of electronic implants in treating conditions that range from acute coronary events to traumatic injury. However, standard permanent electronic hardware acts as a nidus for infection: bacteria form biofilms along percutaneous wires, or seed haematogenously, with the potential to migrate within the body and to provoke immune-mediated pathological tissue reactions. The associated surgical retrieval procedures, meanwhile, subject patients to the distress associated with re-operation and expose them to additional complications...

UNLABELLED: Spinal cord injury (SCI) activates macrophages, endowing them with both reparative and pathological functions. The mechanisms responsible for these divergent functions are unknown but are likely controlled through stochastic activation of different macrophage receptor subtypes. Various danger-associated molecular patterns released from dying cells in the injured spinal cord likely activate distinct subtypes of macrophage pattern recognition receptors, including bacterial toll-like receptors (TLRs) and fungal C-type lectin receptors (e...

We have developed a tablet-based application, the High-Definition Fiber Tracking Report App, to enable clinicians and patients in research studies to see and understand damage from Traumatic Brain Injury (TBI) by viewing 2-dimensional and 3-dimensional images of their brain, with a focus on white matter tracts with quantitative metrics. The goal is to visualize white matter fiber tract injury like bone fractures; that is, to make the "invisible wounds of TBI" understandable for patients. Using mobile computing technology (iPad), imaging data for individual patients can be downloaded remotely within hours of a magnetic resonance imaging brain scan...

To determine whether the exposure to long term enriched environment (EE) would result in a continuous improvement of neurological recovery and ameliorate the loss of brain tissue after traumatic brain injury (TBI) vs. standard housing (SH). Male Sprague-Dawley rats (300-350 g, n=28) underwent lateral fluid percussion brain injury or SHAM operation. One TBI group was held under complex EE for 90 days, the other under SH. Neuromotor and sensorimotor dysfunction and recovery were assessed after injury and at days 7, 15, and 90 via Composite Neuroscore (NS), RotaRod test, and Barnes Circular Maze (BCM)...

Objective. PTSD and major depression occur frequently following traumatic exposure, both as separate disorders and concurrently. Although much of Turkey is under threat of severe earthquakes, risk factors for developing psychiatric disorders among Turkish children have not yet been studied. The aim of the study was to examine risk factors for PTSD and depression develpoment in children. Method. A total of 160 survivors (102 girls and 58 boys) severely impacted by Turkey's 7.4-magnitude quake participated in a psychiatric interview 6-20 weeks after the disaster...

Traumatic brain injury (TBI) is one of the most common causes of death in ordinary accidents, natural disasters, or warfare. The gold standard for diagnosis of TBI is the CT scan; a delay of diagnostics or medical care is the strongest independent predictor of mortality of TBI patients--particularly in the case of a surgically treatable intracranial hematoma. The proper classification of these patients is of major importance in situations where a CT is not accessible. A portable screening device that uses near-infrared spectroscopy (NIRS) technology allows a preliminary estimate of an intracranial hematoma...

Bouldering is a new trend sport which has become popular in recent years. From April 2011 to June 2012 a total of 5 patients with elbow dislocations from bouldering were admitted to our level 1 trauma center. The injuries varied from simple elbow dislocations to complex fracture dislocations. Elbow dislocations occurred during falling backwards when patients tried to protect themselves by retroversion of both arms. In all cases the falling height was less than 4 meters. The bouldering injury pattern, the diagnostic and therapeutic management as well as the rehabilitation program are described in detail in this article...

OBJECTIVE: Coagulopathy is a complication of traumatic brain injury and its presence after injury has been identified as a risk factor for prognosis. It was our aim to determine whether neurologic findings reflected by Glasgow Coma Scale at initial resuscitation can predict hemocoagulative disorders resulting from traumatic brain injury that may aggravate clinical sequelae and outcome in children. DESIGN: A retrospective analysis of 200 datasets from children with blunt, isolated traumatic brain injury documented in the Trauma Registry of the Deutsche Gesellschaft für Unfallchirurgie was conducted...

OBJECTIVES: To date, there is increasing evidence for the role of endothelins in the pathophysiological development of cerebral vasospasms associated with a variety of neurological diseases, e.g., stroke and subarachnoid hemorrhage. In contrast, only little is known regarding the role of endothelins in impaired cerebral hemodynamics after traumatic brain injury. Therapeutic work in blocking the endothelin system has led to the discovery of a number of antagonists potentially useful in restoring cerebral blood flow after traumatic brain injury, potentially reducing the detrimental effects of secondary brain injury...

BACKGROUND: Artificial dural substitutes are increasingly being used in decompressive craniectomy to prevent peridural fibrosis and facilitate cranioplasty for patients with head injury. The safety of the dural substitute should be systemically evaluated. We focus on Neuro-Patch (B. Braun, Boulogne, France), a nonabsorbable substitute and commonly used by neurosurgeons. METHODS: In this retrospective study, 132 patients undergoing 135 craniectomies and cranioplasties for traumatic brain injury were enrolled...

INTRODUCTION: Retrospective studies have demonstrated a potential survival benefit from transfusion strategies using an early and more balanced ratio between fresh frozen plasma (FFP) concentration and packed red blood cell (pRBC) transfusions in patients with acute traumatic coagulopathy requiring massive transfusions. These results have mostly been derived from non-head-injured patients. The aim of the present study was to analyze whether a regime using a high FFP:pRBC transfusion ratio (FFP:pRBC ratio >1:2) would be associated with a similar survival benefit in severely injured patients with traumatic brain injury (TBI) (Abbreviated Injury Scale (AIS) score, head ≥ 3) as demonstrated for patients without TBI requiring massive transfusion (≥ 10 U of pRBCs)...

Cranial traumas from gunshot wounds are characterised by the impact of a high velocity projectile. There are therefore serious, life threatening traumas. CT Scan is essential in the emergency setting for initial evaluation of traumatic bone and parenchymatous injuries to determine the indication for neurosurgery and appropriate medical management. In case of survival, CT Scan and MRI can be used to monitor progress and any possible complications, in particular vascular or infectious complications which are specific to this type of injury...

Pericarditis is an inflammation of the pericardium with accumulation of serous or fibrinous inflammatory products. In cattle, it is almost always attributable to a reticular foreign body that has penetrated the reticular wall, diaphragm and pericardial sac. The lead signs of pericarditis are tachycardia, muffled heart sounds, asynchronous abnormal heart sounds, distension of the jugular veins and submandibular, brisket and ventral abdominal oedema. The glutaraldehyde test is an important diagnostic tool because it is positive in >90% of affected cattle...
