Mild traumatic brain injury typically involves temporary impairment of neurological function. Previous studies used water pressure or rotational injury for designing the device to make a rat a mild traumatic brain injury model. The objective of this study was to make a simple model of causing mild traumatic brain injury in rats. The device consisted of a free-fall impactor that was targeted onto the rat skull. The weight (175 g) was freely dropped 30 cm to rat's skull bregma. We installed a safety device made of acrylic panel...

We present the case of an 18-year-old young man with severe persistent knee pain secondary to a popliteal artery thrombosis. This occurred as a result of a fall from a bicycle. Acute compartment syndrome refers to the sequelae that can occur because of increased fascial compartment pressures, such as crush injuries, burns, traumatic or spontaneous hemorrhage, or constrictive casts. Increased pressures in nonelastic fascial compartments result in decreased perfusion distally, leading to ischemia of muscles and neurovascular tissue...

Background Intracranial pseudoaneurysm formation due to a ruptured non-traumatic aneurysm is extremely rare. We describe the radiological findings and management of pseudoaneurysms due to ruptured cerebral aneurysms in our case series and previously reported cases. Patients and methods Four additional and 20 reported patients presenting with subarachnoid hemorrhage (SAH) are included. Radiological findings and clinical features of these patients were reviewed. Results In our series, three-dimensional computed tomographic angiography (3D-CTA) and/or angiography showed an irregular- or snowman-shaped cavity extending from the parent artery...

BACKGROUND: Little data exist regarding the practice of sodium management in acute neurologically injured patients. This study describes the practice variations, thresholds for treatment, and effectiveness of treatment in this population. METHODS: This retrospective, multicenter, observational study identified 400 ICU patients, from 17 centers, admitted for ≥48 h with subarachnoid hemorrhage (SAH), traumatic brain injury (TBI), intraparenchymal hemorrhage, or intracranial tumors between January 1, 2011 and July 31, 2012...

BACKGROUND: Fever is a common occurrence in the Neurocritical Care Unit (NCCU). It is reported that up to 50 % of these fevers are associated with a non-infectious source. As this is a diagnosis of exclusion, a complete fever evaluation must be done to rule out infection. Procalcitonin (PCT) has been identified as a possible biomarker to distinguish infectious from non-infectious etiologies of fever. We hypothesized that PCT could be used as a predictor of infectious fever in febrile patients with intracranial hemorrhage admitted to the NCCU...

[BACKGROUND]: Traumatic brain injury (TBI) produces lasting neurological deficits that plague patients and physicians. To date, there is no effective method to combat the source of this problem. Here, we utilized a mild, closed head TBI model to determine the modulatory effects of a natural dietary compound, astaxanthin (AST). AST is centrally active following oral administration and is neuroprotective in experimental brain ischemia/stroke and subarachnoid hemorrhage (SAH) models. We examined the effects of oral AST on the long-term neurological functional recovery and histological outcomes following moderate TBI in a mice model...

REVIEW

Assessment of neurologic injury and the evolution of severe neurologic injury is limited in comatose or critically ill patients that lack a reliable neurologic examination. For common yet severe pathologies such as the comatose state after cardiac arrest, aneurysmal subarachnoid hemorrhage (aSAH), and severe traumatic brain injury (TBI), critical medical decisions are made on the basis of the neurologic injury. Decisions regarding active intensive care management, need for neurosurgical intervention, and withdrawal of care, depend on a reliable, high-quality assessment of the true state of neurologic injury, and have traditionally relied on limited assessments such as intracranial pressure monitoring and electroencephalogram...

Traumatic injury is a significant cause of morbidity and mortality in the United States. Massive hemorrhage is responsible for the vast majority of deaths. Evolution in trauma treatment has resulted in major improvements to emergency care. Tranexamic acid (TXA), an antifibrinolytic agent, is synthetically derived from amino acids. The CRASH-2 study demonstrated that the early administration of TXA results in significant decreases in morbidity and mortality. Experiences by coalition forces in Southwest Asia found a substantial increase in survival of trauma patients with early TXA administration...

A prototype cone-beam CT (CBCT) head scanner featuring model-based iterative reconstruction (MBIR) has been recently developed and demonstrated the potential for reliable detection of acute intracranial hemorrhage (ICH), which is vital to diagnosis of traumatic brain injury and hemorrhagic stroke. However, data truncation (e.g. due to the head holder) can result in artifacts that reduce image uniformity and challenge ICH detection. We propose a multi-resolution MBIR method with an extended reconstruction field of view (RFOV) to mitigate truncation effects in CBCT of the head...

BACKGROUND: Traumatic disruption of the pelvic ring is a significant cause of life-threatening hemorrhage. For those patients who survive the initial injury, these fractures are associated with long periods of immobilization and intense rehabilitation. There is little published information available regarding long-term functional outcomes in these patients. This study evaluated the impact of severe pelvic fractures on those long-term outcomes. METHODS: All patients with severe pelvic fractures over an 18-year period were identified...

BACKGROUND: Arterial shunting is a well-described method to control hemorrhage and rapidly re-establish flow, but optimal shunt dwell times remain controversial. We hypothesized that prolonged shunt dwell times of >6 hours are related to adverse outcomes after major arterial injury. METHODS: A review (2005-2013) of all patients with arterial shunts placed after traumatic injury at our urban Level-I trauma center was undertaken. Patients who expired prior to shunt removal (n=7) were excluded...

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has received increasing attention for critically uncontrolled hemorrhagic shock. However, the efficacy of REBOA in patients in youth is unknown. OBJECTIVES: The aim of this study was to evaluate the mortality and characteristics of patients of age ≤ 18 years with severe traumatic injury who received REBOA. METHODS: We retrospectively analyzed observational cohort data from the Japan Trauma Data Bank (JTDB) from 2004 to 2015...

BACKGROUND: Platelet dysfunction has been described as an early component of trauma induced coagulopathy (TIC). The platelet component of TIC remains to be fully elucidated and translatable animal models are required to facilitate mechanistic investigations. We sought to determine if the early platelet dysfunction described in trauma patients could be recapitulated in an non-human primate (NHP) model of poly-traumatic hemorrhagic shock. METHODS: Twenty-four male Rhesus Macaques weighting 7-14 kilograms were subjected to 60 minutes (min) severe pressure-targeted controlled hemorrhagic shock (HS) with and without other injuries...

BACKGROUND: Providing the correct level of care for patients with intracerebral hemorrhage (ICH) is crucial, but the level of care needed at initial presentation may not be clear. This study evaluated factors associated with admission to intensive care unit (ICU) level of care. METHODS: This is an observational study of all adult patients admitted to our institution with non-traumatic supratentorial ICH presenting within 72 h of symptom onset between 2009-2012 (derivation cohort) and 2005-2008 (validation cohort)...

BACKGROUND: Uncontrollable chest wall bleeding secondary to thoracic trauma has been a challenging problem faced by surgeons. Thoracic packing has been described as a good alternative although most thoracic surgeons avoid it because of the potential deleterious effects on cardiopulmonary function. METHODS: We describe a selective gauze packing technique of the thoracic wall preserving cardiopulmonary function in 3 patients with uncontrollable bleeding, where gauze packs were placed on bleeding areas holding them in a "sandwich-like" arrangement between the skin and the pleura and tightly fixed with coated wire stitches using internal and external-thoracic Ventrofil® devices...

Central nervous system infratentorial superficial siderosis (iSS) is increasingly detected by blood-sensitive MRI sequences. Despite this, there are no standardized diagnostic criteria, and the clinical-radiological spectrum, causes and optimum investigation strategy are not established. We reviewed clinical and radiological details of patients with iSS assessed at a specialist neurological center from 2004-2016 using pre-defined standardized radiological criteria. All imaging findings were rated blinded to clinical details...

Traumatic brain injury (TBI) is a major cause of disability and death in patients who experience a traumatic injury. Mitochondrial dysfunction is one of the main factors contributing to secondary injury in TBI-associated brain damage. Evidence of compromised mitochondrial function after TBI has been, but the molecular mechanisms underlying the pathogenesis of TBI are not well understood. Silent information regulator family protein 1 (SIRT1), a member of the NAD(+)-dependent protein deacetylases, has been shown to exhibit neuroprotective activities in animal models of various pathologies, including ischemic brain injury, subarachnoid hemorrhage and several neurodegenerative diseases...
