Preparing to manage weapons of mass destruction events challenges emergency services systems neighboring Syria every day. Understanding injury from explosives is essential for all providers of emergency care in both civilian and military settings. In this case, the authors present a 22-year-old man who was admitted to the emergency department with displaced skull fracture, epidural hemorrhage ...

After complement system (CS) activation, the sequential production of complement products increases cell injury and death through opsonophagocytosis, cytolysis, adaptive, and inflammatory cell responses. These responses potentiate cerebral ischemia-reperfusion (IR) injury after ischemic stroke and reperfusion. Activation of the CS via mannose binding lectin (MBL)-initiated lectin pathway is kno...

To investigate the relationship between neuropathologic damage and cerebral metabolic alterations during hypothermia in the neonatal animal, 7 day old Sprague-Dawley rats were subjected to unilateral common carotid artery ligation and hypoxia at 37 degrees C, 29 degrees C, and 21 degrees C. At 37 degrees C, animals had extensive infarction of tectum and ipsilateral cerebral hemisphere, and mark...

Objective(s): This study aimed to evaluate the potential role of hydrogen in rats after cerebral ischemic/reperfusion (I/R) injury. Materials and Methods: The experimental samples were composed of sham group, model group of rats that received middle cerebral artery occlusion (MCAO) for 2 hr followed by reperfusion for 24 hr, and the hydr...

Objective(s):Global cerebral ischemia-reperfusion injury causes loss of pyramidal cells in CA1 region of hippocampus. In this study, we investigated the possible neuroprotective effects of the ethanol extract of Cyperus rotundus (EECR) on a model of global transient ischemia in rat, by evaluating the pathophysiology of the hippocampal tissue and spatial memory. Materials and Methods: Treatment ...

OBJECTIVE The aims of this study were to document the incidence of impaired cerebral autoregulation in children with traumatic brain injury using transcranial Doppler ultrasonography and to examine the relationship between autoregulatory capacity and outcome in children following traumatic brain injury. DESIGN Prospective cohort study. SETTING Harborview Medical Center (level I pediatric tr...

The purpose of this study was to investigate whether autologous transplantation of adipose-derived mesenchymal stem cells (ADMSCs) has a neuroprotective effect against cerebral ischemia/reperfusion (I/R) injury in rats and to explore the possible underlying mechanisms. Adult male Sprague-Dawley rats were randomly assigned into the sham, I/R injury model (I/R), and model plus autologous transpla...

Inflammatory damage plays an important role in cerebral ischemic pathogenesis and may represent a promising target for treatment. Sulforaphane exerts protective effects in a rat model of focal cerebral ischemia/reperfusion injury by alleviating brain edema. However, the possible mechanisms of sulforaphane after cerebral ischemia/reperfusion injury have not been fully elucidated. Therefore, in t...

Hypoxic ischemic brain injury (HIBI) after cardiac arrest (CA) is a leading cause of mortality and long-term neurologic disability in survivors. The pathophysiology of HIBI encompasses a heterogeneous cascade that culminates in secondary brain injury and neuronal cell death. This begins with primary injury to the brain caused by the immediate cessation of cerebral blood flow following CA. There...
