Further investigation of the applicability of head injury criterion and the associated scaling laws with finite element modelling - Ruan S, Zhao W, Li H, Cui S, He L.

To test the applicability of Head Injury Criterion (HIC), three different-sized (5th, 50th, 95th percentile) finite element head models were developed from medical CT scan images of living humans. These models were scaled to generate six scaled models. The...

CONCLUSIONS: The present study provides information that may help to establish standard dimensions of lateral masses of the atlas vertebrae among the normal Indian population. We demonstrate that there is no significant difference when compared with the Western population. The results presented here will be of use to clinicians as they may inform preoperative planning for lateral mass fixation surgeries. PMID: 31795022 [PubMed]

CONCLUSIONS Our study, in which no X-ray examination revealed possible intracranial bleeding, clearly shows that nowadays the plain radiograph of the skull does not bring any benefit in the diagnosis of minor traumatic brain injury. Key words:skull X-ray, CT of the head, head injury, minor traumatic brain injury. PMID: 31748109 [PubMed - in process]

Conclusion: In this cohort of patients there was no evidence to support the hypothesis that axial injury is related to worse functional independence compared to extra-axial injury at rehabilitation admission and discharge. Utilizing MRI findings or other outcome measures, such as the 10 meter ambulation test or cognitive tests, may provide better sensitivity to potential functional differences.

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. METHODS: This is a retrospective study of patients presenting to the emergency department from January 2016 to December 2017 with Glasgow Coma Scale (GCS) scores> 8 and an initial abnormal CT scan, who underwent repeat CT during their in-hospital medical management. Patients who underwent surgery after the first CT scan, had a GCS score

CONCLUSIONS: ASDH was not a common cause of CSDH. Head CT at the time of trauma that precedes CSDH often showed SDE. Such SDE that precedes CSDH was often close to the detection limit of CT immediately after the injury but became more apparent from the day after the injury. PMID: 31675707 [PubMed - in process]

Intracranial bleeding is common after traumatic brain injury (TBI) and can cause brain herniation and death. We aimed to assess the effects of tranexamic acid in patients with TBI.MethodsThis randomised, placebo-controlled trial was done in 175 hospitals in 29 countries. Adults with TBI who were within 3 h of injury, had a Glasgow Coma Scale (GCS) score of 12 or lower or any intracran...

Conclusions No clinically significant brain injury (requiring intervention) was seen in this cohort. These findings support delaying imaging in neurologically intact children to obtain MRI after hospital admission, thus, limiting radiation exposure.

ConclusionsOur results demonstrate that signs and symptoms of orbital fractures may be useful for predicting these injuries, and a decision instrument could be used in the ED to identify patients likely to benefit from extending the radiation field to include the orbits where CT of the head is already planned. This work is however exploratory; and further prospective validation is required before a robust instrument can be recommended for clinical use.
