Role of repeat CT in mild to moderate head injury: an institutional study.

Patients with traumatic brain injury (TBI) often undergo repeat head CT scans to identify the possible progression of injury. The objective of this study is to evaluate the need for routine repeat head CT scans in patients with mild to moderate head injury and an initial positive abnormal CT scan.

Predicting orbital fractures in head injury: a preliminary study of clinical findings.

Patients presenting to emergency departments (EDs) following head injury often undergo computed tomography (CT) of the head to exclude traumatic brain injury. In many cases, this does not show the maxillofacial skeleton. A proportion of these patients also sustain facial fractures, and when fractures involve the orbits, CT imaging is useful in diagnosis and management; obtaining a second scan may cause delay, incur greater cost, and increase radiation dose. The aim of this preliminary study was to examine t...

In this article, we review the pathophysiology, classifications, signs and symptoms, and management of traumatic brain injury. We also discuss the importance of preventing a secondary injury during recovery by educating families about head injury sequ...

Computed tomography findings after head injury preceding chronic subdural hematoma.

Head CT is sometimes performed immediately after minor head injury; however, which cases develop into chronic subdural hematoma (CSDH) remains unclear. Here, the authors retrospectively reviewed the rare cases of CSDH treated surgically in which early head CT had been performed after the initial head trauma.

The costs of traumatic head injury and associated factors at University of Gondar Specialized Referral Hospital, Northwest Ethiopia.

Head injuries account for 650,000 annual deaths worldwide. The cost for treating head injury was estimated at US $200 million annually. This contributes to economic impoverishment in low income countries like Ethiopia. Hence, this study was aimed to assess the cost of Traumatic Head Injury (THI) and associated factors in the University of Gondar Specialized Referral Hospital.

Smaller Head Circumference Combined with Lower Education Predicts High Risk of Incident Dementia: The Shanghai Aging Study.

An important index of brain reserve is the maximal attained brain size, which can be estimated by measuring the head circumference (HC). We investigated the association of HC and education with incident dementia in a population-based study of Chinese older adults.

Complicated mild traumatic brain injury in older adults: Post-concussion symptoms and functional outcome at one week post injury.

Mild Traumatic Brain Injury (MTBI) is commonly categorized as when injury severity criteria are mild, but an intracranial abnormality is present on acute neuroimaging. The current study examined whether functional outcomes differed at one week post injury among older adult patients based on injury severity and acute computed tomography (CT) findings. Participants (≥55 years-old; = 173) presenting sequentially to the emergency department with a head injury were divided into three groups: complicated M...

Protective Headgear Attenuates Forces on the Inner Table and Pressure in the Brain Parenchyma During Blast and Impact: An Experimental Study Using a Simulant-Based Surrogate Model of the Human Head.

Military personnel sustain head and brain injuries as a result of ballistic, blast, and blunt impact threats. Combat helmets are meant to protect the heads of these personnel during injury events. Studies show peak kinematics and kinetics are attenuated using protective headgear during impacts; however, there is limited experimental biomechanical literature that examines whether or not helmets mitigate peak mechanics delivered to the head and brain during blast. While the mechanical links between blast and ...

Photobiomodulation Therapy for Repeated Closed Head Injury in Rats.

Repeated traumatic brain injury, leads to cumulative neuronal injury and neurological impairments. There are currently no effective treatments to prevent these consequences. Growing interest is building in the use of transcranial photobiomodulation (PBM) therapy to treat TBI. Here, we examined PBM in a repeated closed head injury (rCHI) rat model. Rats were administered a total of three closed head injuries, with each injury separated by 5 days. PBM treatment was initiated 2 h after the first injury and a...

Intra-Articular Radial Head Fractures: A Deceptive Type of Injury.

Isolated intra-articular radial head (IARH) fractures in skeletally immature patients represent a rare injury. Despite their initial benign radiologic appearance, these fractures are at risk for progressive radial head subluxation and may end with degenerative irreversible changes of the radiocapitellar joint. The aim of this study is to highlight the seriousness of these injuries and the importance of early diagnosis and a proper follow-up to achieve optimal outcomes.

A comparison of the prevalence of orthostatic hypotension between older patients with Alzheimer's Disease, Lewy body dementia, and without dementia.

Orthostatic hypotension (OH) is reported to be more prevalent particularly in patients with Dementia with Lewy bodies (DLB) because of the autonomic dysfunction, but prevalence of OH is not known in patients with Alzheimer Disease (AD). The aim of the present study was to determine whether OH can be used to distinguish DLB from AD. 38 patients with DLB, 88 patients with AD and 521 patients without dementia, underwent Comprehensive Geriatric Assessment. OH were evaluated for the 1st (OH1) and 3rd (OH3) minut...

Percutaneous endoscopic gastrostomy feeding is beneficial in patients with advanced dementia.

We aimed to show the long-term results of patients who received percutaneous endoscopic gastrostomy (PEG) tubes and to evaluate the usefulness of this method in advanced dementia patients, which is considered to be of controversial benefit in the literature. Therefore, we compared three groups of patients: advanced dementia patients fed via PEG, stroke patients fed via PEG and advanced dementia patients not fed via PEG.

Limitations of the European barrier crash testing regulation relating to occupant safety.

The safety of roadside restraint systems in Europe is ensured by the EN 1317 regulation. The ability of the barrier to mitigate injury to the occupants of vehicles is tested according to two occupant injury metrics: Acceleration Severity Index (ASI) and Theoretical Head Impact Velocity (THIV). Both metrics aim to predict occupant head injury from vehicle kinematics, despite the potential to easily measure actual head kinematics from instrumented Anthropomorphic Test Dummies, a non-instrumented version of wh...

Randomized controlled trial of Cerebrolysin's effects on long-term histological outcomes and functional recovery in rats with moderate closed head injury.

The authors previously demonstrated that Cerebrolysin is effective for treatment of mild closed head injury (CHI) when administered 4 hours after injury. The aim of this study was to determine Cerebrolysin's effects on functional and histological outcomes in rats subjected to moderate CHI.

Prediction of pedestrian brain injury due to vehicle impact using computational biomechanics models: Are head-only models sufficient?

Accident reconstruction using computational biomechanics models plays an important role in research and prevention of human brain injury caused by car-to-pedestrian impacts. Finite element (FE) "head-only" models (that represent only the pedestrian head and brain) used in such reconstruction do not account for the influence of the rest of the pedestrian body on the head kinematics due to the accident and, consequently, on the brain injury risk prediction. Application of full-scale FE pedestrian models, on t...

Head first - Review of epilepsy head injury risk and protection.

The causes of falls and resultant head injuries in people with epilepsy are complex and represent important clinical issues significantly impacting on safety, quality of life and long-term prognosis. A general solution for many years has been to provide helmets for head protection. There is poor understanding of the influencing risk factors and solutions to give person-centred clinical advice.

Driving Fitness in Different Forms of Dementia: An Update.

Most forms of dementia are associated with progressive cognitive and noncognitive impairments that can severely affect fitness to drive. Whether safe driving is still possible in the single case, however, is often difficult to decide and may be dependent on both severity and type of the respective dementia syndrome. Particularly in early disease stages, Alzheimer disease dementia (ADD) and different types of non-Alzheimer dementias, such as vascular dementia (VaD), frontotemporal dementia (FTD), dementia wi...

Shooting through windscreens: ballistic injury assessment using a surrogate head model-two case reports.

A synthetic head model developed to reproduce military injuries was assessed in two different scenarios involving shooting through intermediate targets (a laminated vehicle windscreen in scenario 1 and a military helicopter windscreen in scenario 2) with 7.62 × 39-mm mild steel core (MSC) ammunition. The injury patterns resulting from the two scenarios were assessed by a military radiologist and a forensic pathologist with combat injury experience and found to be clinically realistic.

Simulated single-bicycle crashes in the VTI crash safety laboratory.

The objective of this study was to examine the influence of bicycle design and speed on the head impact when suffering from a single-bicycle crash, and the possibility to study this using crash tests. Simulations of single-bicycle crashes were performed in the VTI crash safety laboratory. Two bicycle crash scenarios were simulated: "a sudden stop" and "sideways dislocation of the front wheel"; using four different bicycle types: a "lady's bicycle", a commuter bicycle, a recumbent bicycle and a pedelec; at t...

Increased severity of the CHIMERA model induces acute vascular injury, sub-acute deficits in memory recall, and chronic white matter gliosis.

Traumatic brain injury (TBI) is a leading cause of death and disability in modern societies. Diffuse axonal and vascular injury are nearly universal consequences of mechanical energy impacting the head and contribute to disability throughout the injury severity spectrum. CHIMERA (Closed Head Impact Model of Engineered Rotational Acceleration) is a non-surgical, impact-acceleration model of rodent TBI that reliably produces diffuse axonal injury characterized by white matter gliosis and axonal damage. At imp...

The use of donepezil in gait disorders in eldery patients with dementia.

Donepezil is the most commonly used cholinesterase inhibitor. The indication for its use is Alzheimer's disease. A number of clinical studies have shown its effectiveness in vascular dementia, dementia with Lewy bodies, Parkinson's disease with dementia, dementia due to traumatic brain injury. It is shown that dementia is a risk factor for falls, and standard measures to prevent falls in the elderly are ineffective in patients with cognitive impairment. This article provides a review of publications on the ...

Thresholds for the assessment of inflicted head injury by shaking trauma in infants: a systematic review.

In order to investigate potential causal relations between the shaking of infants and injuries, biomechanical studies compare brain and skull dynamic behavior during shaking to injury thresholds. However, performing shaking tolerance research on infants, either in vivo or ex vivo, is extremely difficult, if not impossible. Therefore, infant injury thresholds are usually estimated by scaling or extrapolating adult or animal data obtained from crash tests or whiplash experiments. However, it is doubtful wheth...
