Risk of Delayed Intracranial Hemorrhage in Anticoagulated Patients with Mild Traumatic Brain Injury: Systematic Review and Meta-Analysis.
Delayed intracranial hemorrhage is a potential complication of head trauma in anticoagulated patients. ⋯ The present study is the first published meta-analysis estimating the risk of delayed intracranial hemorrhage 24 h after head trauma in patients anticoagulated with vitamin K antagonist and normal initial CT scan. In most situations, a repeat CT scan in the emergency department 24 h later is not necessary if the first CT scan is normal. Special care may be required for patients with serious mechanism of injury, patients showing signs of neurologic deterioration, and patients presenting with excessive anticoagulation or receiving antiplatelet co-medication.

Multicenter StudyCOMT and ANKK1 Genetics Interact With Depression to Influence Behavior Following Severe TBI: An Initial Assessment.
Genetic variations in the dopamine (DA) system are associated with cortical-striatal behavior in multiple populations. This study assessed associations of functional polymorphisms in the ankyrin repeat and kinase domain (ANKK1; Taq1a) and catechol-O-methyltransferase (COMT; Val158Met) genes with behavioral dysfunction following traumatic brain injury (TBI). ⋯ In the context of depression, Val158Met and Taq1a polymorphisms are individually associated with behavioral dysfunction 12 months following severe TBI, with preliminary evidence suggesting cumulative, or perhaps epistatic, effects of COMT and ANKK1 on behavioral dysfunction.

Traumatic atlanto-occipital dislocation (AOD) is an ominous injury with high mortality and morbidity in trauma patients. Improved survival has been observed with advancements in pre-hospital and hospital care. Furthermore, high quality imaging studies are accessible at most trauma centers; these are crucial for prompt diagnosis of AOD. ⋯ We found that patients with TBI are eight times more likely to die than patients without TBI. A high degree of suspicion for AOD during pre-hospital care, as well as, prompt diagnosis and management in the trauma center play a key role in the treatment of this devastating injury. The relationship between survival and factors such as TBI and SCI should be further explored.

The purpose of this study was to explore the inter-device reliability of NPi-100 pupillometers (NeuroOptics, Inc.). The pupillary examination is a fundamental element of the neurological exam. Current evidence suggests that the traditional examination of the pupil with a hand held flashlight has limited inter-rater reliability. ⋯ There was no statistically significant difference between the mean maximum pupil size at rest, the minimum pupil size during light stimulation, and the mean pupil reactivity, for both the right and left eye, when assessed by two investigators, each with a different pupillometer. In addition, Cohen's Kappa assessments of pupil size and reactivity revealed an almost perfect agreement between the two pupillometers for the maximum pupil size, the minimum pupil size, and for pupil reactivity for both eyes. There is a high inter-device reliability of automated pupillary assessments by two practitioners examining the same patient using different NPi-100 pupillometers.

Intracranial neurosurgical disorders are important causes of mortality and disability worldwide. Low tri-iodothyronine (T3) syndrome is a common complication in critically ill patients and is associated with a poor prognosis. ⋯ Low T3 syndrome is a common complication in patients suffering from intracranial neurosurgical disorders and is associated with greater disease severity, complicated clinical course, and greater mortality and handicap rates. However, it remains unclear if low T3 syndrome can impact the findings of currently available clinical prognostic models and if management of low T3 syndrome can improve outcomes in neurosurgical patients.
