BACKGROUND CONTEXT: Damage to the spinal cord can result in irreversible impairment or complete loss of motor, sensory, and autonomic functions. Riluzole and dantrolene have been shown to provide neuroprotection by reducing neuronal apoptosis after brain and spinal cord injury (SCI) in several animal models of neurological disorders. As these drugs protect the injured spinal cord through different mechanisms, we investigated the cumulative effects of riluzole and dantrolene. PURPOSE: This study aimed to investigate the neuroprotective efficacy of the combined administration of riluzole and dantrolene in experimental thoracic SCI...

Background: The epidemiologic characteristics and outcomes of pediatric traumatic brain injury (pTBI) have not been adequately documented from the rapidly developing countries in the Arab Middle East. We aimed to describe the hospital-based epidemiologic characteristics, injury mechanisms, clinical presentation, and outcomes of pTBI and analyze key characteristics and determinant of pTBI that could help to make recommendations for policies to improve their care. Methods: We conducted a retrospective observational study in a level 1 trauma center (2010-2014) for all pTBI patients...

Brain edema and the associated increase in intracranial pressure are major consequences of traumatic brain injury (TBI) that accounts for most early deaths after TBI. We recently showed that acute severe trauma to cultured astrocytes results in cell swelling. We further examined whether trauma induces cell swelling in neurons and microglia. We found that severe trauma also caused cell swelling in cultured neurons, whereas no swelling was observed in microglia. While severe trauma caused cell swelling in both astrocytes and neurons, mild trauma to astrocytes, neurons, and microglia failed to cell swelling...

Objective: Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. Methods: We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery)...

BACKGROUND: Diffuse axonal injury (DAI) on MRI has been associated with poor functional outcome after moderate-severe traumatic brain injury (msTBI). Yet, DAI assessment with highly-sensitive MRI-techniques is unfeasible in the acute trauma setting, and CT remains the key diagnostic modality despite its lower sensitivity. We sought to determine whether CT-defined-hemorrhagic-DAI (hDAI) is associated with discharge and favorable 3-and 12-month functional outcome (Glasgow Outcome Score ≥4) after msTBI...

Background: The most widely used methods of describing traumatic brain injury (TBI) are the Glasgow Coma Scale (GCS) and the Abbreviated Injury Scale (AIS). Recent evidence suggests that presenting GCS in older patients may be higher than that in younger patients for an equivalent anatomical severity of TBI. This study aimed to assess these observations with a propensity-score matching approach using the data from Trauma Registry System in a Level I trauma center. Methods: We included all adult patients (aged ≥20 years old) with moderate to severe TBI from 1 January 2009 to 31 December 2016...

The events leading to traumatic brain injury (TBI) are often psychologically traumatic (e.g., motor vehicle accidents) or occur within a broader context of psychological trauma, such as military combat or recurrent interpersonal violence. In such cases, posttraumatic stress disorder (PTSD) may develop and serve to complicate TBI recovery. Likewise, brain trauma may impede emotional resolution following psychological trauma exposure. This article addresses comorbid PTSD and TBI, including the epidemiology of PTSD following TBI; the clinical presentation of the comorbidity; potential mechanisms that complicate recovery from psychological trauma and TBI when they co-occur; and considerations for the clinical management of PTSD in the context of TBI, including implications for both psychosocial and psychopharmacological PTSD treatments...

The crossbow is an ancient ranged weapon originally conceived for war and hunting. Although nowadays its use in warfare has been surpassed by firearms, it continues to be used in hunting, sports and recreation. The authors present the case of a 40-year-old man who suffered from severe depression. When his condition further deteriorated, doctors ordered a forced hospitalization but, just a few hours before the measure became effective, the man committed suicide using a crossbow. The autopsy and police investigation showed possession of the crossbow darts which the man used to shoot himself in the head...

BACKGROUND: Patients presenting with an early GCS score of 3-5 after blunt or penetrating skull-brain assaults are categorized as having sustained a very severe Traumatic Brain Injury (vs-TBI). This category is often overlooked in literature. Impact on patients and families lives however is huge and the question "whether to surgically treat or not" frequently poses a dilemma to treating physicians. Little is known about mortality and outcome, compared to what is known for the group of severe TBI patients (s-TBI) (GCS 3- 8)...

Case: We report a case of post-traumatic hypopituitarism in a 9-year-old boy who was injured in a car accident. Outcome: Post-traumatic hypopituitarism might be caused by moderate to severe head trauma, and while this possibility has recently drawn attention in adults, few reports are available regarding children. Our patient experienced head and facial injury, resulting in post-traumatic hypopituitarism. Six hours after injury he suffered from diabetes insipidus and hormone replacement therapy was started...

PURPOSE: To report a novel treatment method for vertebral artery injury. Vertebral artery injuries may be caused during trauma by fracture and excessive motion with subluxation from C2 to C6 in spite of vertebral artery deeply seated and normally well protected inside the transverse foramen. Optimal medical management of the occluded vertebral artery has yet to be determined. METHODS: We report on a severely displaced C2-C3 fracture that was found to have a vertebral artery injury...

Traumatic brain injury is a major cause of morbidity and mortality worldwide. Pathophysiologic mechanisms of secondary brain injury are complex and still not fully understood. Cerebrospinal fluid deserves attention to detect infectious complications and to identify biomarkers of disease severity and impending secondary brain injury. As an adjunct, cerebral microdialysis (CMD) allows online measurements of biomarkers derived directly from brain extracellular fluid. We critically review relevant literature related to infectious complications detectable in the cerebrospinal fluid in trauma patients...

Mild traumatic brain injury (mTBI) or concussion represents the majority of TBIs brain trauma in the United States. The pathophysiology of mTBI is complex and may include both focal and diffuse injury patterns. In addition to altered circuit dysfunction and diffuse traumatic axonal injury (DTAI), chronic neuroinflammation has also been implicated in the pathophysiology of mTBI. Recently, our laboratory has reported the detrimental effects of mild hyperthermic mTBI in terms of worsening histopathological and behavioral outcomes...

Background: Admission hyperglycemia is associated with higher morbidity and mortality in patients with traumatic brain injury (TBI). Stress-induced hyperglycemia (SIH), a form of hyperglycemia induced by the stress response, is associated with increased patient mortality following TBI. However, admission hyperglycemia occurs not only in SIH but also in patients with diabetic hyperglycemia (DH). Current information regarding whether trauma patients with SIH represent a distinct group with differential outcomes compared to those with DH remains limited...

BACKGROUND: Direct transport of patients with severe traumatic brain injury (sTBI) to trauma centers (TCs) that can provide definitive care results in lower mortality rates. This study investigated the impact of direct versus nondirect transfers on the mortality rates of patients with sTBI. METHODS: Data on patients with TBI admitted between January 1, 2012, and December 31, 2013, to our Level I TC were obtained from the trauma registry. Data included patient age, sex, mechanism, and type of injury, comorbidities, Glasgow Coma Scale, Injury Severity scores, prehospital time, time to request and to transfer, time to initiation of multimodality monitoring and goal-directed therapy protocol, dwell time in the emergency department (EDT), and mortality...
