Multicenter Study Observational StudyTraumatic brain injury patient volume and mortality in neurosurgical intensive care units: a Finnish nationwide study.
Differences in outcomes after traumatic brain injury (TBI) between neurosurgical centers exist, although the reasons for this are not clear. Thus, our aim was to assess the association between the annual volume of TBI patients and mortality in neurosurgical intensive care units (NICUs). ⋯ We did not find any association between annual TBI patient volume and 6-month mortality in NICUs. These findings should be interpreted taking into account that we only included NICUs, which by international standards all treated high volumes of TBI patients, and that we were not able to study the effect of NICU volume on neurological outcome.

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.

Epidemiology and clinical characteristics of traumatic brain injury in Lebanon: A systematic review.
Traumatic brain injury (TBI) is a debilitating medical and emerging public health problem that is affecting people worldwide due to a multitude of factors including both domestic and war-related acts. The objective of this paper is to systematically review the status of TBI in Lebanon - a Middle Eastern country with a weak health system that was chartered by several wars and intermittent outbursts of violence - in order to identify the present gaps in knowledge, direct future research initiatives and to assist policy makers in planning progressive and rehabilitative policies. ⋯ Apparently, status of TBI in Lebanon suffers from several gaps which need to be bridged through implementing more basic, epidemiological, clinical and translational research in this field in the future.

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.

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.
