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...

Objective: Identification and validation of blood-based biomarkers for the diagnosis and prognosis of mild traumatic brain injury (mTBI) is of critical importance. There have been calls for more research on mTBI in older adults. We compared blood-based protein marker glial fibrillary acidic protein (GFAP) concentrations in serum and in plasma within the same cohort of older adults and assessed their ability to discriminate between individuals based on intracranial abnormalities and functional outcome following mTBI.Methods: A sample of 121 older adults [≥50 years old with head computed tomography (CT), n = 92] seeking m...

ConclusionIn this large national cohort, patients with membranous CSDH had a significantly longer interval between head injury and diagnosis compared to other radiological subtypes. This indicates that the radiological appearance of CSDH evolves over time, causing an alteration from different early radiological subtypes to a radiological subtype with membranes.Clinical trial registration numberThe study was approved by the Danish Data Protection Agency (journal no.30-1145).

BACKGROUND The number of trauma patients on prehospital novel oral anticoagulants (NOACs) is increasing. After an initial negative computed tomography of the head (CTH), practice patterns are variable for obtaining repeat CTH to evaluate for delayed intracranial hemorrhage (ICH-d). However, the risks and outcomes of ICH-d for patients on NOACs are unclear. We hypothesized that, for these patients, the incidence of ICH-d is low, similar to that of warfarin, and when it occurs, it does not result in clinically significant worse outcomes. METHODS Five level 1 trauma centers in Northern California participated in a retros...

Conclusions: Patients with mild head trauma on DOAC therapy had a similar prevalence of ICH to that of the control group. Meanwhile, patients on VKA therapy had about twice the ICH prevalence than that on the control group or patients on DOAC, which remained after correcting for age. No significant difference in the need for surgery was determined; however, this result must take into account the very small number of patients needing surgery. PMID: 32585829 [PubMed - in process]

CONCLUSION: Management of this type of patient appeared to be satisfactory. It can be improved by SBT on the basis of the SFMU 2012 consensus conference. There is a need to improve the software used by the emergency departments, which should include the time of trauma and recommendations. The association of the clinic and the biomarkers could help to limit the indications of the CT scan, and thus to have it organized more rapidly. PMID: 32589257 [PubMed - as supplied by publisher]

In conclusion, this population-based cohort study showed that a head CT scan is not associated with increased risk of thyroid disease in patients with minor head injury. The short-term adverse effects on the thyroid could be mild when a regular CT scan is appropriately performed.

Headache is a very common condition that affects up to 60% of the world’s population. In general, headache can be classified into two main categories: primary and secondary headaches. A primary headache is related to increased sensitivities, but not structural alterations of brain tissues. Common primary headaches are migraine with and without aura, tension-type headache, and trigeminal autonomic cephalalgias (headaches, such as cluster headache, that also involve facial pain and autonomic symptoms such as tear production and nasal congestion). Secondary headaches have various underlying causes including structural v...

CONCLUSION: In this study, which was conducted by including all the predictor values of the PECARN guidelines, the rate of compliance with PECARN rules was determined to be very low. Using these rules directly or with modification could establish a starting point for clinicians to reduce the rates of unnecessary CT scans. However, the effects of the clinician's experience, parental expectations, medicolegal constraints and economic factors on the decision making process should not be forgotten.

AbstractThe aim of this study was to determine the potential impact of the Pediatric Emergency Care Applied Research Network (PECARN) rules on the CT rate in a large paediatric minor traumatic head injury (MTHI) cohort and compare this with current national Dutch guidelines. This was a planned sub-study of a prospective multicentre observational study that enrolled 1006 children younger than 18  years with MTHI. We calculated the number of recommended CT scans and described trauma-related CT scan abnormalities. The PECARN rules recommended a significantly lower percentage of CT scans in all age categories, namely 101/...

We present a case of a 15-year-old boy who was stabbed with a bamboo stick in his left eye. The chopsticks passed through the orbit roof and penetrated the skull base. In subsequent days, the patient sustained CSF leak and intracranial infection after an unsatisfied primary treatment in the local hospital and had to request a secondary operation in our department. Computed tomography including plain scan, three dimension reconstruction and computed tomographic angiography are used to determine the course and extent of head injury. A frontal craniotomy was performed. Three pieces of stick were found residual and removed wit...
