Haemostatic and cranial computed tomography characteristics in patients with acute and delayed coagulopathy after isolated traumatic brain injury.
To investigate whether the development of coagulopathy at different stages after isolated traumatic brain injury (TBI) is associated with distinct cranial computed tomography characteristics. ⋯ Not only the mere presence of coagulopathy, but also the course of haemostatic alterations following neurotrauma may hold predictive value for patient outcome, irrespective of the severity level of cerebral injury.

Multiple indicators model of long-term mortality in traumatic brain injury.
To examine the prognostic ability of protein S100B, neuron-specific enolase (NSE) and glial fibrillary acid protein (GFAP) for prediction of 1-year mortality in patients with traumatic brain injury (TBI) in relation to clinical and radiological characteristics of TBI. ⋯ Mortality at 1-year post-TBI is accurately predicted by the combination of GFAP and S100B concentration and clinical and radiological characteristics at admission or in the acute post-injury period.

Review Case ReportsPenetrating brain injury caused by nail guns: two case reports and a review of the literature.
To the best of the authors' knowledge, there are few case reports of penetrating brain injuries (PBI) caused by nail guns and these have usually involved incomplete penetration of the skull. Complete penetration of a nail into the intracranial cavity is extremely rare. ⋯ Here, two such cases are presented. In the first, the nail entered through the right temporal bone, lodged in the right temporal lobe and was removed via craniotomy with intra-operative ultrasound guidance. In the second, the nail destroyed the left parietal bone, damaged the left internal capsule and lodged in the left temporal lobe near the left petrous apex and the brain stem. According to the latest literature retrieval, this is the first reported case of nail-gun injury to the internal capsule. The position of the nail precluded removal without further neurologic damage. Treatment strategies designed to optimize outcome, with or without surgery, and possible complications are discussed in this report.

Review Comparative StudyA clinical comparison of penetrating and blunt traumatic brain injuries.
Traumatic brain injury (TBI) is a leading cause of injury death and long-term disability in the USA. It commonly results from blunt (closed) or penetrating trauma. The majority of civilian TBI is caused by falls or motor vehicle collisions, whereas military TBI mainly results from explosions. Although penetrating injuries are less common than closed injuries in the civilian population, they are far more lethal. Unfortunately, the pathophysiologic differences between penetrating and closed TBI remain poorly understood due to the lack of studies on the subject. Many studies on the prognostic factors of mortality and functional outcome after TBI exclude penetrating brain injuries from their series because they are believed to have a different pathophysiology. ⋯ In view of the incomplete understanding of the impact of mechanism of injury on TBI outcomes, as demonstrated in the current review, new research studies are required to improve evidence-based TBI guidelines tailored especially for penetrating injuries.

Comparative StudyThe reliability of magnetic resonance imaging in traumatic brain injury lesion detection.
This study compares inter-rater-reliability, lesion detection and clinical relevance of T2-weighted imaging (T2WI), Fluid Attenuated Inversion Recovery (FLAIR), T2*-gradient recalled echo (T2*-GRE) and Susceptibility Weighted Imaging (SWI) in Traumatic Brain Injury (TBI). ⋯ T2*-GRE and SWI are more sensitive than T2WI and FLAIR in detecting (haemorrhagic) traumatic punctate lesions. The correlation between number of punctate lesions on T2*-GRE/SWI and the GCS indicates that haemorrhagic lesions are clinically relevant. The considerable inter-rater-disagreement in this study advocates cautiousness in interpretation of punctate lesions using T2WI and FLAIR.
