The United States Department of Defense Blast Injury Research Program Coordinating Office organized the 2015 International State-of-the-Science meeting to explore links between blast-related head injury and the development of chronic traumatic encephalopathy (CTE). Before the meeting, the planning committee examined articles published between 2005 and October 2015 and prepared this literature review, which summarized broadly CTE research and addressed questions about the pathophysiological basis of CTE and its relationship to blast- and nonblast-related head injury...

OBJECTIVE Early withdrawal of life-sustaining treatment due to expected poor prognosis is responsible for the majority of in-house deaths in severe traumatic brain injury (TBI). With increased focus on the decision and timing of withdrawal of care in patients with severe TBI, data on early neurological recovery in patients with a favorable outcome is needed to guide physicians and families. METHODS The authors reviewed prospectively collected data obtained in 1241 patients with head injury who were treated between 1986 and 2012...

BACKGROUND: Traumatic brain fungus is manifestation of neglected head injury. Although rare it is not uncommon. The patients are usually intact with good Glasgow coma (GCS) score inspite of complex injuries and exposed brain parenchyma but morbidity and mortality is very high with time if no proper and timely management is offered. There is very less study on traumatic brain fungus with no defined management protocols. So an attempt was made to explain in details the surgical strategies and other management techniques in patients with traumatic brain fungus...

INTRODUCTION: Traumatic brain injury (TBI) is a public health problem. It is a pathology that causes significant mortality and disability in Colombia. Different calculators and prognostic models have been developed to predict the neurological outcomes of these patients. The Rotterdam computed tomography (CT) score was developed for prognostic purposes in TBI. We aimed to examine the accuracy of the prognostic discrimination and prediction of mortality of the Rotterdam CT score in a cohort of trauma patients with severe TBI in a university hospital in Colombia...

Traumatic brain injury (TBI) is one of the leading causes of death and disability in the population worldwide, with a broad spectrum of symptoms and disabilities. Posttraumatic hyperexcitability is one of the most common neurological disorders that affect people after a head injury. A reliable animal model of posttraumatic hyperexcitability induced by TBI which allows one to test effective treatment strategies is yet to be developed. To address these issues, in the present study, we tested human embryonic stem cell-derived neural stem cell (NSC) transplantation in an animal model of posttraumatic hyperexcitability in which the brain injury was produced in one hemisphere of immunodeficient athymic nude rats by controlled cortical impact, and spontaneous seizures were produced by repeated electrical stimulation (kindling) in the contralateral hemisphere...

Focused ultrasound (FUS)-mediated blood-brain barrier disruption (BBBD) can enable even large therapeutics such as stem cells to enter the brain from the bloodstream. However, the efficiency is relatively low. Our previous study showed that human neural progenitor cells (hNPCs) loaded with superparamagnetic iron oxide nanoparticles (SPIONs) in culture were attracted by an external magnetic field. In vivo, enhanced brain retention was observed near a magnet mounted on the skull in a rat model of traumatic brain injury, where BBBD also occurs...

Mild traumatic brain injury (mTBI) represents a significant public healthcare concern, accounting for the majority of all head injuries. While symptoms are generally transient, some patients go on to experience long-term cognitive impairments and additional mild impacts can result in exacerbated and persisting negative outcomes. To date, studies using a range of experimental models have reported chronic behavioral deficits in the presence of axonal injury and inflammation following repeated mTBI; assessments of oxidative stress and myelin pathology have thus far been limited...

More than 80% of head trauma patients suffer from mild traumatic brain injury (mTBI). However, even mTBI carries the risk of late pituitary dysfunction. A predictive biomarker at the time of injury which could identify patients who subsequently may develop permanent pituitary dysfunction would help to direct patients towards endocrine care. We enrolled 508 traumatic brain injury patients (406 with mTBI) into our study. Blood samples were collected for identification of predictive biomarkers of late pituitary dysfunction at the time of admission...

BACKGROUND: Often the clinician is faced with a diagnostic and therapeutic dilemma in patients with concomitant traumatic brain injury (TBI) and hemorrhagic shock (HS), as rapid deterioration from either can be fatal. Knowledge about outcomes after concomitant TBI and HS may help prioritize the emergent management of these patients. We hypothesized that patients with concomitant TBI and HS (TBI + HS) had worse outcomes and required more intensive care compared with patients with only one of these injuries...

Our understanding of the diverse physiological manifestations of concussion is changing rapidly. This has an influence on the clinical assessment of patients who have sustained a concussion. The 2017 Consensus Statement on Concussion in Sport states that numerous post-injury clinical findings, such as cognitive deficits, post-traumatic headaches, dizziness, difficulties with oculomotor function, and depression have all been associated with a poorer prognosis in concussed patients. This demonstrates that there are several potential clinical manifestations after head injury warranting clinical evaluation...

OBJECTIVE: This study examined changes in postconcussive symptoms (PCS) over the acute postinjury recovery period, focusing on how daily PCSs differ between mild traumatic brain injury (mTBI) and other injury types. SETTING: An urban emergency department (ED) in Western Pennsylvania. SUBJECTS: A total of 108 adult patients with trauma being discharged from the ED were recruited and grouped by injury type: mild TBI (mTBI; n = 39), head injury without mTBI (HI: n = 16), and non-head-injured trauma controls (TCs: n = 53)...

Traumatic optic neuropathy (TON) is a devastating cause of permanent visual loss following blunt injury to the head. Animal models for TON exist, but most fail to recapitulate the clinical scenario of closed head indirect trauma to the nerve and subsequent neurodegeneration. Thus, we developed a clinically-relevant animal model for TON using a novel ultrasonic pulse injury modality (sonication-induced TON; SI-TON). To trigger TON, a microtip probe sonifier was placed on the supraorbital ridge directly above the entrance of the optic nerve into the bony canal...

More than 12,000 children are seen in Dutch emergency departments with a mild traumatic head injury (MTHI) every year. In The Netherlands, the paediatric MTHI guidelines are primarily based on the Pediatric Emergency Care Applied Research Network study (1). The guidelines define several criteria, based on the patient's age, to help clinicians to decide whether they need to perform a computed tomography (CT) scan (2). This national study determined the adherence to the guidelines and the reasons why clinicians deviated from them...

PURPOSE: There is a lack of association between coagulation biomarkers and long-term mortality in severe trauma. We aimed to investigate the association between coagulation biomarkers on admission and outcome of late stage of trauma. METHODS: This retrospective observational study included patients admitted with severe trauma between 2012 and 2015. We used the area under the receiver operating characteristic curve (AUROC) of coagulation biomarkers to determine 28-day mortality...

BACKGROUND: Maintaining brain oxygenation status is the main goal of treatment in severe traumatic brain injury (TBI). Jugular venous oxygen saturation (SjvO2) monitoring is a technique to estimate global balance between cerebral oxygen supply and its metabolic requirement. Full Outline of Responsiveness (FOUR) score, a new consciousness measurement scoring, is expected to become an alternative for Glasgow Coma Scale (GCS) in evaluating neurologic status of patients with severe traumatic head injury, especially for those under mechanical ventilation...

The effects of trauma in children are different due to association with some anatomical and physiological differences compared with adults. The role of neuroimaging gains importance in early detection of traumatic brain injuries and prevention of secondary post-traumatic complications. Many algorithms are described for children with head trauma to decide the necessity of a computed tomography scan. The aims of this article are to describe differences of these algorithms, the mechanism of traumatic brain injury with radiological imaging findings in the pediatric population, and explain complications of undiagnosed traumatic brain lesions...
