  3. Acute brain trauma.

    In the 20th century, the complications of head injuries were controlled but not eliminated. The wars of the 21st century turned attention to blast, the instant of impact and the primary injury of concussion. Computer calculations have established that in the first 5 milliseconds after the impact, four independent injuries on the brain are inflicted: 1) impact and its shockwave, 2) deceleration, 3) rotation and 4) skull deformity with vibration (or resonance). The recovery, pathology and symptoms after acute brain trauma have always been something of a puzzle. The variability of these four modes of injury, along with a variable reserve of neurones, explains some of this problem.

    The brain has different responses to traumatic injury as a function of its developmental stage. As a model of injury to the immature brain, the piglet shares numerous similarities in regards to morphology and neurodevelopmental sequence compared to humans. This chapter describes a piglet scaled focal contusion model of traumatic brain injury that accounts for the changes in mass and morphology of the brain as it matures, facilitating the study of age-dependent differences in response to a comparable mechanical trauma.

    Experimental studies targeting traumatic brain injury (TBI) have reported that erythropoietin (EPO) is an endogenous neuroprotectant in multiple models. In addition to its neuroprotective effects, it has also been shown to enhance reparative processes including angiogenesis and neurogenesis. Based on compelling pre-clinical data, EPO was tested by the Operation Brain Trauma Therapy (OBTT) consortium to evaluate therapeutic potential in multiple TBI models along with biomarker assessments. Based on the pre-clinical TBI literature, two doses of EPO (5000 and 10,000 IU/kg) were tested given at 15 min after moderate fluid percussion brain injury (FPI), controlled cortical impact (CCI), or penetrating ballistic-like brain injury (PBBI) with subsequent behavioral, histopathological, and biomarker outcome assessments. There was a significant benefit on beam walk with the 5000 IU dose in CCI, but no benefit on any other motor task across models in OBTT. Also, no benefit of EPO treatment across the three TBI models was noted using the Morris water maze to assess cognitive deficits. Lesion volume analysis showed no treatment effects after either FPI or CCI; however, with the 5000 IU/kg dose of EPO, a paradoxical increase in lesion volume and percent hemispheric tissue loss was seen after PBBI. Biomarker assessments included measurements of glial fibrillary acidic protein (GFAP) and ubiquitin C-terminal hydrolase-L1 (UCH-L1) in blood at 4 or 24 h after injury. No treatment effects were seen on biomarker levels after FPI, whereas treatment at either dose exacerbated the increase in GFAP at 24 h in PBBI but attenuated 24-4 h delta UCH-L1 levels at high dose in CCI. Our data indicate a surprising lack of efficacy of EPO across three established TBI models in terms of behavioral, histopathological, and biomarker assessments. Although we cannot rule out the possibility that other doses or more prolonged treatment could show different effects, the lack of efficacy of EPO reduced

    Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease confirmed at postmortem. Those at highest risk are professional athletes who participate in contact sports and military personnel who are exposed to repetitive blast events. All neuropathologically confirmed CTE cases, to date, have had a history of repetitive head impacts. This suggests that repetitive head impacts may be necessary for the initiation of the pathogenetic cascade that, in some cases, leads to CTE. Importantly, while all CTE appears to result from repetitive brain trauma, not all repetitive brain trauma results in CTE. Magnetic resonance imaging has great potential for understanding better the underlying mechanisms of repetitive brain trauma. In this review, we provide an overview of advanced imaging techniques currently used to investigate brain anomalies. We also provide an overview of neuroimaging findings in those exposed to repetitive head impacts in the acute/subacute and chronic phase of injury and in more neurodegenerative phases of injury, as well as in military personnel exposed to repetitive head impacts. Finally, we discuss future directions for research that will likely lead to a better understanding of the underlying mechanisms separating those who recover from repetitive brain trauma vs. those who go on to develop CTE.

    Levetiracetam (LEV) is an antiepileptic agent targeting novel pathways. Coupled with a favorable safety profile and increasing empirical clinical use, it was the fifth drug tested by Operation Brain Trauma Therapy (OBTT). We assessed the efficacy of a single 15 min post-injury intravenous (IV) dose (54 or 170 mg/kg) on behavioral, histopathological, and biomarker outcomes after parasagittal fluid percussion brain injury (FPI), controlled cortical impact (CCI), and penetrating ballistic-like brain injury (PBBI) in rats. In FPI, there was no benefit on motor function, but on Morris water maze (MWM), both doses improved latencies and path lengths versus vehicle (p < 0.05). On probe trial, the vehicle group was impaired versus sham, but both LEV treated groups did not differ versus sham, and the 54 mg/kg group was improved versus vehicle (p < 0.05). No histological benefit was seen. In CCI, there was a benefit on beam balance at 170 mg/kg (p < 0.05 vs. vehicle). On MWM, the 54 mg/kg dose was improved and not different from sham. Probe trial did not differ between groups for either dose. There was a reduction in hemispheric tissue loss (p < 0.05 vs. vehicle) with 170 mg/kg. In PBBI, there was no motor, cognitive, or histological benefit from either dose. Regarding biomarkers, in CCI, 24 h glial fibrillary acidic protein (GFAP) blood levels were lower in the 170 mg/kg group versus vehicle (p < 0.05). In PBBI, GFAP blood levels were increased in vehicle and 170 mg/kg groups versus sham (p < 0.05) but not in the 54 mg/kg group. No treatment effects were seen for ubiquitin C-terminal hydrolase-L1 across models. Early single IV LEV produced multiple benefits in CCI and FPI and reduced GFAP levels in PBBI. LEV achieved 10 points at each dose, is the most promising drug tested thus far by OBTT, and the only drug to improve cognitive outcome in any model. LEV has been advanced to testing in the micropig model in OBTT. PMID:26671550

    Sexual aggression and violence against women (VAM) are not only social problems; they are mental health problems. Women who experience sexual trauma often express disruptions in emotional and cognitive processes, some of which lead to depression and post-traumatic stress disorder (PTSD). Animal models of neurogenesis and learning suggest that social yet aggressive interactions between a pubescent female and an adult male can disrupt processes of learning related to maternal care, which in turn reduce survival of new neurons in the female hippocampus. Mental and Physical (MAP) Training is a novel clinical intervention that was translated from neurogenesis research. The intervention, which combines meditation and aerobic exercise, is currently being used to help women learn to recover from traumatic life experiences, especially those related to sexual violence and abuse.

    The current conflicts in Iraq and Afghanistan have resulted in a large cohort of military personnel exposed to combat-related psychological trauma as well as biomechanical trauma, including proximity to blast events. Historically, the long-term effects of both types of trauma have been viewed as having different neural substrates, with some controversy over the proper attribution of such symptoms evident after each of the major conflicts of the last century. Recently, great effort has been directed toward distinguishing which neuropsychiatric sequelae are due to which type of trauma. Of interest, however, is that the chronic effects of exposure to either process are associated with a significant overlap in clinical symptoms. Furthermore, similar brain regions are vulnerable to the effects of either psychological or biomechanical trauma, raising the possibility that shared mechanisms may underlie the clinically observed overlap in symptom profile. This paper reviews the literature on the neural substrate of biomechanical and psychological injury and discusses the implications for evaluation and treatment of the neuropsychiatric sequelae of these processes.

    Traumatic brain and spine injury (TBI/TSI) is a leading cause of death and lifelong disability in children. The biomechanical properties of the child's brain, skull, and spine, the size of the child, the age-specific activity pattern, and variance in trauma mechanisms result in a wide range of age-specific traumas and patterns of brain and spine injuries. A detailed knowledge about the various types of primary and secondary pediatric head and spine injuries is essential to better identify and understand pediatric TBI/TSI, which enhances sensitivity and specificity of diagnosis, will guide therapy, and may give important information about the prognosis. The purposes of this chapter are to: (1) discuss the unique epidemiology, mechanisms, and characteristics of TBI/TSI in children; (2) review the anatomic and functional imaging techniques that can be used to study common and rare pediatric TBI/TSI and their complications; (3) comprehensively review frequent primary and secondary brain injuries; and (4) to give a short overview of two special types of pediatric TBI/TSI: birth-related and nonaccidental injuries.

    Brain metabolism is thought to be maintained by neuronal-glial metabolic coupling. Glia take up glutamate from the synaptic cleft for conversion into glutamine, triggering glial glycolysis and lactate production. This lactate is shuttled into neurons and further metabolized. The origin and role of lactate in severe traumatic brain injury (TBI) remains controversial. Using a modified weight drop model of severe TBI and magnetic resonance (MR) spectroscopy with infusion of 13C-labeled glucose, lactate, and acetate, the present study investigated the possibility that neuronal-glial metabolism is uncoupled following severe TBI. Histopathology of the model showed severe brain injury with subarachnoid and hemorrhage together with glial cell activation and positive staining for Tau at 90 min post-trauma. High resolution MR spectroscopy of brain metabolites revealed significant labeling of lactate at C-3 and C-2 irrespective of the infused substrates. Increased 13C-labeled lactate in all study groups in the absence of ischemia implied activated astrocytic glycolysis and production of lactate with failure of neuronal uptake (i.e. a loss of glial sensing for glutamate). The early increase in extracellular lactate in severe TBI with the injured neurons rendered unable to pick it up probably contributes to a rapid progression toward irreversible injury and pan-necrosis. Hence, a method to detect and scavenge the excess extracellular lactate on site or early following severe TBI may be a potential primary therapeutic measure. PMID:24849602

    Continued problematic behavior in children and adolescents after brain trauma is a major barrier to medical care, rehabilitation, and eventual independent living. The present study demonstrates the application of already well-developed behavior analysis techniques to the early posttrauma expression of behavior problems during hospital recovery. To satisfy concerns regarding both cost and individualized treatment, interventions were carried out primarily by regular hospital staff (nurses and therapists), medical record data were used to document gains, and time series, within subject designs were used to show experimental control. Four patients (three male and one female) ranging in age from 10 to 16 years, received intervention based on behavior analysis techniques, which reduced disruption and increased cooperation with therapy and medical care. Behavior analysis techniques will be relevant to future rehabilitation research to the extent that the posttrauma patient's behavior is effected by environmental consequences as demonstrated here.

We argue that these measures access the inherently probabilistic nature of causal influences in the brain, and are thus better suited for large-scale brain network analysis than are DC-based measures. Our work is consistent with recent advances in the philosophical study of probabilistic causality, which originated from inherent conceptual problems with deterministic regularity theories. It also resonates with concepts of stochasticity that were involved in establishing modern physics. In summary, we argue that probabilistic causality is a conceptually appropriate foundation for describing neural causality in the brain.

    Background Although the association between psychological trauma and early maladaptive schemas (EMS) is well established in the literature, no study to date has examined the relationship of EMS to PTSD and psychopathologies beyond depression and anxiety in a sample of adult survivors of interpersonal trauma. This information may be useful in helping our understanding on how to best treat interpersonal trauma. Objective We set out to investigate the association between EMS and common forms of psychopathology in a sample of women with a history of interpersonal trauma (n=82). We have hypothesised that survivors of interpersonal trauma will present with elevated EMS scores compared to a non-clinical control group (n=78). We have also hypothesised that unique schemas will be associated with unique psychopathological entities and that subgroups of interpersonal trauma survivors would be present in our sample, with subgroups displaying different profiles of schema severity elevations. Method Participants completed measures of trauma, psychopathology, dissociation, self-esteem, and the Young Schema Questionnaire. Results It was found that survivors of interpersonal trauma displayed elevated EMS scores across all 15 schemas compared to controls. Although the pattern of associations between different psychopathological features and schemas appears to be rather complex, schemas in the domains of Disconnection and Impaired Autonomy formed significant associations with all psychopathological features in this study. Conclusions Our findings support the usefulness of cognitive behavioural interventions that target schemas in the domains of Disconnection and Impaired Autonomy in an effort to modify existing core beliefs and decrease subsequent symptomatology in adult survivors of interpersonal trauma. Highlights of the article Interpersonal trauma survivors are distinguished primarily by a generalised elevation of their maladaptive schemas, rather than a unique schema profile

    Abstract Outcomes after pediatric traumatic brain injury (TBI) are related to pre-treatment factors including age, injury severity, and mechanism of injury, and may be positively affected by treatment at trauma centers relative to non-trauma centers. This study estimated the proportion of children with moderate to severe TBI who receive care at trauma centers, and examined factors associated with receipt of care at adult (ATC), pediatric (PTC), and adult/pediatric trauma centers (APTC), compared with care at non-trauma centers (NTC) using a nationally representative database. The Kids' Inpatient Database was used to identify hospitalizations for moderate to severe pediatric TBI. Pediatric inpatients ages 0 to 17 years with at least one diagnosis of TBI and a maximum head Abbreviated Injury Scale score of ≥3 were studied. Multinomial logistic regression was performed to examine factors predictive of the level and type of facility where care was received. A total of 16.7% of patients were hospitalized at NTC, 44.2% at Level I or II ATC, 17.9% at Level I or II PTC, and 21.2% at Level I or II APTC. Multiple regression analyses showed receipt of care at a trauma center was associated with age and polytrauma. We concluded that almost 84% of children with moderate to severe TBI currently receive care at a Level I or Level II trauma center. Children with trauma to multiple body regions in addition to more severe TBI are more likely to receive care a trauma center relative to a NTC. PMID:23343131

    Chronic traumatic encephalopathy (CTE) has been linked to participation in contact sports such as boxing and American football. CTE results in a progressive decline of memory and cognition, as well as depression, suicidal behavior, poor impulse control, aggressiveness, parkinsonism, and, eventually, dementia. In some individuals, it is associated with motor neuron disease, referred to as chronic traumatic encephalomyelopathy, which appears clinically similar to amyotrophic lateral sclerosis. Results of neuropathologic research has shown that CTE may be more common in former contact sports athletes than previously believed. It is believed that repetitive brain trauma, with or possibly without symptomatic concussion, is responsible for neurodegenerative changes highlighted by accumulations of hyperphosphorylated tau and TDP-43 proteins. Given the millions of youth, high school, collegiate, and professional athletes participating in contact sports that involve repetitive brain trauma, as well as military personnel exposed to repeated brain trauma from blast and other injuries in the military, CTE represents an important public health issue. Focused and intensive study of the risk factors and in vivo diagnosis of CTE will potentially allow for methods to prevent and treat these diseases. Research also will provide policy makers with the scientific knowledge to make appropriate guidelines regarding the prevention and treatment of brain trauma in all levels of athletic involvement as well as the military theater.

  7. Developmental Decrease of Neuronal Chloride Concentration Is Independent of Trauma in Thalamocortical Brain Slices

    The intraneuronal chloride concentration ([Cl-]i) is paramount for determining the polarity of signaling at GABAA synapses in the central nervous system. Sectioning hippocampal brain slices increases [Cl-]i in the superficial layers. It is not known whether cutting trauma also increases [Cl-]i in the neocortex and thalamus, and whether the effects of trauma change during development. We used Cl- imaging to study the [Cl-]i vs. the distance from the cut surface in acute thalamocortical slices from mice at developmental ages ranging from post-natal day 5 (P5) to P20. We demonstrate: 1) [Cl-]i is higher in the most superficial areas in both neocortical and thalamic brain slices at all ages tested and, 2) there is a developmental decrease in [Cl-]i that is independent of acute trauma caused by brain slicing. We conclude that [Cl-]i has a developmental progression during P5-20 in both the neocortex and thalamus. However, in both brain regions and during development the neurons closest to the slicing trauma have an elevated [Cl-]i. PMID:27337272

    Abstract Although they are less severe than a full blown concussive episodes, subconcussive impacts happen much more frequently and current research has suggested this form of head trauma may have an accumulative effect and lead to neurological impairment later in life. To investigate the acute effects that subconcussive head trauma may have on the default mode network of the brain resting-state, functional magnetic resonance was performed. Twenty-four current collegiate rugby players were recruited and all subjects underwent initial scanning 24 h prior to a scheduled full contact game to provide a baseline. Follow-up scanning of the rugby players occurred within 24 h following that game to assess acute effects from subconcussive head trauma. Differences between pre-game and post-game scans showed both increased connectivity from the left supramarginal gyrus to bilateral orbitofrontal cortex and decreased connectivity from the retrosplenial cortex and dorsal posterior cingulate cortex. To assess whether or not a history of previous concussion may lead to a differential response following subconcussive impacts, subjects were further divided into two subgroups based upon history of previous concussion. Individuals with a prior history of concussion exhibited only decreased functional connectivity following exposure to subconcussive head trauma, while those with no history showed increased connectivity. Even acute exposure to subconcussive head trauma demonstrates the ability to alter functional connectivity and there is possible evidence of a differential response in the brain for those with and without a history of concussion.

    Diffusion tensor imaging (DTI) was used to study traumatic brain injury. The impact-acceleration trauma model was used in rats. Here, in addition to diffusivities (mean, axial and radial), fractional anisotropy (FA) was used, in particular, as a parameter to characterize the cerebral tissue early after trauma. DTI was implemented at 7 T using fast spiral k-space sampling and the twice-refocused spin echo radiofrequency sequence for eddy current minimization. The method was carefully validated on different phantom measurements. DTI of a trauma group (n = 5), as well as a sham group (n = 5), was performed at different time points during 6 h following traumatic brain injury. Two cerebral regions, the cortex and corpus callosum, were analyzed carefully. A significant decrease in diffusivity in the trauma group versus the sham group was observed, suggesting the predominance of cellular edema in both cerebral regions. No significant FA change was detected in the cortex. In the corpus callosum of the trauma group, the FA indices were significantly lower. A net discontinuity in fiber reconstructions in the corpus callosum was observed by fiber tracking using DTI. Histological analysis using Hoechst, myelin basic protein and Bielschowsky staining showed fiber disorganization in the corpus callosum in the brains of the trauma group. On the basis of our histology results and the characteristics of the impact-acceleration model responsible for the presence of diffuse axonal injury, the detection of low FA caused by a drastic reduction in axial diffusivity and the presence of fiber disconnections of the DTI track in the corpus callosum were considered to be related to the presence of diffuse axonal injury.

    While, historically, the disabled body has appeared in literature as "monstrous," burgeoning psychological theories of the Victorian period predicated an unusual shift. In a culture of sexual anxiety and fears of devolution and moral decay, the physically disabled and "weak" are portrayed as strangely free from moral corruption. Unlike the cultural link between deviance and disability witnessed in the medical literature and eugenic approach to generation, authors of narrative fiction-particularly Charles Dickens, but Wilkie Collins, Charlotte Yonge, and others as well-portray disabled characters as "purified," and trauma itself as potentially sanitizing. This present paper argues that such constructions were made possible by developments in the treatment of insanity. "Curing 'Moral Disability': Brain Trauma and Self-Control in Victorian Fiction," examines the concept of trauma-as-cure. Throughout the Victorian period, case studies on brain trauma appeared in widely circulated journals like the Lancet, concurrently with burgeoning theories about psychological disturbance and "moral insanity." While not widely practiced until the early twentieth century, attempts at surgical "cures" aroused curiosity and speculation-the traumatic event that could free sufferers from deviance. This work provides a unique perspective on representations of disability as cure in the nineteenth century as a means of giving voice to the marginalized, disabled, and disempowered.

    Background: Following severe trauma to the brain (whether internally generated by seizures, tumors or externally caused by collision with or penetration of objects) individuals may experience initial coma state followed by slow recovery and rehabilitation treatment. At present there is no objective biometric to track the daily progression of the person for extended periods of time. Objective: We introduce new analytical techniques to process data from physically wearable sensors and help track the longitudinal progression of motions and physiological states upon the brain trauma. Setting and Participant: The data used to illustrate the methods were collected at the hospital settings from a pregnant patient in coma state. The patient had brain trauma from a large debilitating seizure due to a large tumor in the right pre-frontal lobe. Main Measures: We registered the wrist motions and the surface-skin-temperature across several daily sessions in four consecutive months. A new statistical technique is introduced for personalized analyses of the rates of change of the stochastic signatures of these patterns. Results: We detected asymmetries in the wrists’ data that identified in the dominant limb critical points of change in physiological and motor control states. These patterns could blindly identify the time preceding the baby’s delivery by C-section when the patient systematically brought her hand to her abdominal area. Changes in temperature were sharp and accompanied by systematic changes in the statistics of the motions that rendered her dominant wrist’s micro-movements more systematically reliable and predictable than those of the non-dominant writst. Conclusions: The new analytics paired with wearable sensing technology may help track the day-by-day individual progression of a patient with post brain trauma in clinical settings and in the home environment.

    The method to induce unilateral cryogenic lesions was first described in 1958 by Klatzo. We describe here an adaptation of this model that allows reliable measurement of lesion volume and vasogenic edema by 2, 3, 5-triphenyltetrazolium chloride-staining and Evans blue extravasation in mice. A copper or aluminium cylinder with a tip diameter of 2.5 mm is cooled with liquid nitrogen and placed on the exposed skull bone over the parietal cortex (coordinates from bregma: 1.5 mm posterior, 1.5 mm lateral). The tip diameter and the contact time between the tip and the parietal skull determine the extent of cryolesion. Due to an early damage of the blood brain barrier, the cryogenic cortical injury is characterized by vasogenic edema, marked brain swelling, and inflammation. The lesion grows during the first 24 hours, a process involving complex interactions between endothelial cells, immune cells, cerebral blood flow, and the intracranial pressure. These contribute substantially to the damage from the initial injury. The major advantage of the cryogenic lesion model is the circumscribed and highly reproducible lesion size and location.

    Operant conditioning-based behavioural interventions are commonly used for the behavioural problems of individuals with mental retardation. There is also growing evidence of the benefits of these interventions for treating some of the behavioural problems of individuals with acquired cognitive deficits resulting from brain trauma. However, the effects of behavioural interventions on behavioural problems occurring during acute neurorehabilitation, when orientation and memory are most impaired, have not been studied. In this empirical case study, operant conditioning-based procedures were applied with an 8-year-old girl recovering from brain trauma and related neurosurgery. Screaming, non-compliance and aggression, which were disrupting rehabilitation therapies and follow-up neuroimaging, were treated using differential positive reinforcement techniques. Beneficial behavioural intervention effects were demonstrated using single-subject experimental methods. Aberrant behaviour during physical and occupational therapies was reduced, and cooperation with a computerized tomography (CT) scan without sedation was accomplished using operant behavioural intervention. Results support the use of operant interventions early in recovery from brain trauma, and highlight the importance of interdisciplinary collaboration for the implementation and further study of early behavioural interventions.

    Objective: To image β-amyloid (Aβ) plaque burden in long-term survivors of traumatic brain injury (TBI), test whether traumatic axonal injury and Aβ are correlated, and compare the spatial distribution of Aβ to Alzheimer disease (AD). Methods: Patients 11 months to 17 years after moderate–severe TBI underwent 11C-Pittsburgh compound B (11C-PiB)-PET, structural and diffusion MRI, and neuropsychological examination. Healthy aged controls and patients with AD underwent PET and structural MRI. Binding potential (BPND) images of 11C-PiB, which index Aβ plaque density, were computed using an automatic reference region extraction procedure. Voxelwise and regional differences in BPND were assessed. In TBI, a measure of white matter integrity, fractional anisotropy, was estimated and correlated with 11C-PiB BPND. Results: Twenty-eight participants (9 with TBI, 9 controls, 10 with AD) were assessed. Increased 11C-PiB BPND was found in TBI vs controls in the posterior cingulate cortex and cerebellum. Binding in the posterior cingulate cortex increased with decreasing fractional anisotropy of associated white matter tracts and increased with time since injury. Compared to AD, binding after TBI was lower in neocortical regions but increased in the cerebellum. Conclusions: Increased Aβ burden was observed in TBI. The distribution overlaps with, but is distinct from, that of AD. This suggests a mechanistic link between TBI and the development of neuropathologic features of dementia, which may relate to axonal damage produced by the injury. PMID:26843562

  17. Mental Trauma Experienced by Caregivers of patients with Diffuse Axonal Injury or Severe Traumatic Brain Injury

    Context As with care giving and rehabilitation in chronic illnesses, the concern with traumatic brain injury (TBI), particularly with diffuse axonal injury (DAI), is that the caregivers are so overwhelmingly involved in caring and rehabilitation of the victim that in the process they become traumatized themselves. This review intends to shed light on the hidden and silent trauma sustained by the caregivers of severe brain injury survivors. Motor vehicle accident (MVA) is the highest contributor of TBI or DAI. The essence of trauma is the infliction of pain and suffering and having to bear the pain (i.e. by the TBI survivor) and the burden of having to take care and manage and rehabilitate the TBI survivor (i.e. by the TBI caregiver). Moreover many caregivers are not trained for their care giving task, thus compounding the stress of care giving and rehabilitating patients. Most research on TBI including DAI, focus on the survivors and not on the caregivers. TBI injury and its effects and impacts remain the core question of most studies, which are largely based on the quantitative approach. Evidence Acquisition Qualitative research can better assess human sufferings such as in the case of DAI trauma. While quantitative research can measure many psychometric parameters to assess some aspects of trauma conditions, qualitative research is able to fully reveal the meaning, ramification and experience of TBI trauma. Both care giving and rehabilitation are overwhelmingly demanding; hence , they may complicate the caregivers’ stress. However, some positive outcomes also exist. Results Caregivers involved in caring and rehabilitation of TBI victims may become mentally traumatized. Posttraumatic recovery of the TBI survivor can enhance the entire family’s closeness and bonding as well as improve the mental status of the caregiver. Conclusions A long-term longitudinal study encompassing integrated research is needed to fully understand the traumatic experiences of

    The detection of sever brain trauma remains difficult when employing traditional methods in part due to the pathophysiological complexity of the condition. Current brain trauma detection includes schemes that require bulky, expensive equipment to deduce regional cerebral blood flow. These methods are difficult to use in conjunction with patients requiring ongoing intensive care and constant monitoring. Our previous studies have shown that surface- enhanced Raman spectroscopy (SERS) with silver colloids has the ability to measure physiological concentrations of in vivo brain analytes linked to brain trauma using short scan times. More recently, after implementing a damage model for ischemia in rats, an ex vivo analysis of brain microdialysis samples shows a correlation between SERS spectral features and the occurrence and location of known localized ischaemia. A near real-time measurement system could provide relevant clinical information in anticipation of surgical or pharmaceutical interventions for severely head injured patients.

    A building will more likely collapse if it does not have any proper foundations. Similarly, the design philosophy of Triadic Game Design (TGD) needs to reside on solid building blocks, otherwise the concept will collapse as well. In this level I will elaborate on these building blocks. First I will explain what the general idea of TGD is. It is a design philosophy, for sure, but one which stresses that an “optimum” needs to be found in a design space constituted by three different worlds: Reality, Meaning, and Play. Additionally, these worlds need to be considered simultaneously and be treated equally. The latter requires balancing the worlds which may result in different tensions, within and between two or three of the worlds. I continue by discussing each of the worlds and showing their perspective on the field of games with a meaningful purpose. From this, we clearly see that it is feasible to think of each world and that the idea makes sense. I substantiate this further by relating the notion of player and similar approaches to this framework. This level is quite a tough pill to swallow yet essential for finishing the other levels. Do not cheat or simply skip this level, but just take a big cup of coffee or tea and start reading it.

  20. Prevention of brain trauma by legislation, regulation, and improved technology: a focus on motor vehicles.

    More than half of all brain trauma is caused by motor vehicle crashes. Prevention strategies that reduce the likelihood of motor vehicle crashes or injuries to occupants will also prevent trauma. Many effective strategies have yet to be applied on a large scale. Roadway design improvements such as removal of fixed objects from roadsides, widening roadside recovery zones, installing dividers between opposing lanes of traffic, and replacing fixed utility poles with breakaway designs, have been effective in reducing crashes and injuries. Driver measures of documented benefit include the 55 mph speed limit, safety belt use laws, 21 year legal drinking age, administrative license suspension for drinking drivers, and driving curfews and postponement of licensure for teenagers. Motor vehicle safety has improved greatly since the National Highway Traffic Safety Administration began regulating vehicle design. Significant design requirements include lap and shoulder belts in front seat positions, and, more recently, automatic safety belts or air bags in front seat positions, head restraints in front seat positions, reinforcing side and roof beams, and the center-mounted brake light. The most significant future advance will be the provision of full front seat air bags in all passenger vehicles. As much as one-quarter of brain trauma can be prevented or reduced in severity by this measure alone. Further safety requirements should include head restraints in rear positions, a-pillar, b-pillar, and roof padding, antilock brakes, and a vehicle rollover standard. PMID:1588622

    Progressive hemorrhagic injury (PHI) can be divided into coagulopathy-related PHI and normal coagu- lation PHI. Coagulation disorders after traumatic brain injuries can be included in trauma-induced coagulopathy (TIC). Some studies showed that TIC is associated with PHI and increases the rates of disability and mortality. In this review, we discussed some mechanisms in TIC, which is of great importance in the development of PHI, including tissue factor (TF) hypothesis, protein C pathway and thrombocytopenia. The main mechanism in the relation of TIC to PHI is hypocoagulability. We also reviewed some coagulopathy parameters and proposed some possible risk factors, predictors and therapies. PMID:27321300

This is a novel and emerging domain, since it employs the use of robotic devices, adaptation software and machine learning to facilitate interactive and adaptive rehabilitation care. We used Protégé 4.2 and Protégé-Owl schema editor. The primary goal of this ontology is to enable the reuse of the domain knowledge. CABROnto has nine main classes, more than 50 subclasses, existential and cardinality restrictions. The ontology can be found online at Bioportal.

    Objectives Cumulative head trauma may alter brain structure and function. We explored the relationship between exposure variables, cognition and MRI brain structural measures in a cohort of professional combatants. Methods 224 fighters (131 mixed martial arts fighters and 93 boxers) participating in the Professional Fighters Brain Health Study, a longitudinal cohort study of licensed professional combatants, were recruited, as were 22 controls. Each participant underwent computerised cognitive testing and volumetric brain MRI. Fighting history including years of fighting and fights per year was obtained from self-report and published records. Statistical analyses of the baseline evaluations were applied cross-sectionally to determine the relationship between fight exposure variables and volumes of the hippocampus, amygdala, thalamus, caudate, putamen. Moreover, the relationship between exposure and brain volumes with cognitive function was assessed. Results Increasing exposure to repetitive head trauma measured by number of professional fights, years of fighting, or a Fight Exposure Score (FES) was associated with lower brain volumes, particularly the thalamus and caudate. In addition, speed of processing decreased with decreased thalamic volumes and with increasing fight exposure. Higher scores on a FES used to reflect exposure to repetitive head trauma were associated with greater likelihood of having cognitive impairment. Conclusions Greater exposure to repetitive head trauma is associated with lower brain volumes and lower processing speed in active professional fighters. PMID:25633832

    Boxing and other combat sports may serve as a human model to study the effects of repetitive head trauma on brain structure and function. The initial description of what is now known as chronic traumatic encephalopathy (CTE) was reported in boxers in 1928. In the ensuing years, studies examining boxers have described the clinical features of CTE, its relationship to degree of exposure to fighting, and an array of radiologic findings. The field has been hampered by issues related to study design, lack of longitudinal follow-up, and absence of agreed-upon clinical criteria for CTE. A recently launched prospective cohort study of professional fighters, the Professional Fighters Brain Health Study, attempts to overcome some of the problems in studying fighters. Here, we review the cross-sectional results from the first year of the project. PMID:23731821

    The number of sports-related concussions has been steadily rising in recent years. Diminished brain resilience syndrome is a term coined by the lead author to describe a particular physiological state of nutrient functional deficiency and disrupted homeostatic mechanisms leading to increased susceptibility to previously considered innocuous concussion. We discuss how modern day environmental toxicant exposure, along with major changes in our food supply and lifestyle practices, profoundly reduce the bioavailability of neuro-critical nutrients such that the normal processes of homeostatic balance and resilience are no longer functional. Their diminished capacity triggers physiological and biochemical ‘work around’ processes that result in undesirable downstream consequences. Exposure to certain environmental chemicals, particularly glyphosate, the active ingredient in the herbicide, Roundup®, may disrupt the body's innate switching mechanism, which normally turns off the immune response to brain injury once danger has been removed. Deficiencies in serotonin, due to disruption of the shikimate pathway, may lead to impaired melatonin supply, which reduces the resiliency of the brain through reduced antioxidant capacity and alterations in the cerebrospinal fluid, reducing critical protective buffering mechanisms in impact trauma. Depletion of certain rare minerals, overuse of sunscreen and/or overprotection from sun exposure, as well as overindulgence in heavily processed, nutrient deficient foods, further compromise the brain's resilience. Modifications to lifestyle practices, if widely implemented, could significantly reduce this trend of neurological damage. PMID:25024897

    Traumatic brain injury is a common entity. However cerebral infarction in infants is a rare entity while the diagnosis of this pathology in the pediatric population is usually difficult. The mild head trauma is rarely accompanied by intracranial injury and even less, with cerebral infarction. We herein report the first case of cerebral infarction after a mild brain trauma in a 2-year-old Latin-American male patient, in which brain computed tomography (CT) scan was performed on the first day of the accident, showed right hemispheric cerebral ischemia compromising the fronto-parieto-occipital region. Conservative management was established. The patient died at day 5. So Brain CT scan may be beneficial to reveal any hemispheric infarction due to a probable mass effect.

    2015-01-01

    Abstract Significance: Traumatic brain injury (TBI) and spinal cord injury (SCI) are major causes of death and long-term disability worldwide. Despite important pathophysiological differences between these disorders, in many respects, mechanisms of injury are similar. During both TBI and SCI, some cells are directly mechanically injured, but more die as a result of injury-induced biochemical changes (secondary injury). Autophagy, a lysosome-dependent cellular degradation pathway with neuroprotective properties, has been implicated both clinically and experimentally in the delayed response to TBI and SCI. However, until recently, its mechanisms and function remained unknown, reflecting in part the difficulty of isolating autophagic processes from ongoing cell death and other cellular events. Recent Advances: Emerging data suggest that depending on the location and severity of traumatic injury, autophagy flux—defined as the progress of cargo through the autophagy system and leading to its degradation—may be either increased or decreased after central nervous system trauma. Critical Issues: While increased autophagy flux may be protective after mild injury, after more severe trauma inhibition of autophagy flux may contribute to neuronal cell death, indicating disruption of autophagy as a part of the secondary injury mechanism. Future Directions: Augmentation and/or restoration of autophagy flux may provide a potential therapeutic target for treatment of TBI and SCI. Development of those treatments will require thorough characterization of changes in autophagy flux, its mechanisms and function over time after injury. Antioxid. Redox Signal. 23, 565–577.

    Operation Brain Trauma Therapy (OBTT) is a fully operational, rigorous, and productive multicenter, pre-clinical drug and circulating biomarker screening consortium for the field of traumatic brain injury (TBI). In this article, we synthesize the findings from the first five therapies tested by OBTT and discuss both the current work that is ongoing and potential future directions. Based on the results generated from the first five therapies tested within the exacting approach used by OBTT, four (nicotinamide, erythropoietin, cyclosporine A, and simvastatin) performed below or well below what was expected based on the published literature. OBTT has identified, however, the early post-TBI administration of levetiracetam as a promising agent and has advanced it to a gyrencephalic large animal model--fluid percussion injury in micropigs. The sixth and seventh therapies have just completed testing (glibenclamide and Kollidon VA 64), and an eighth drug (AER 271) is in testing. Incorporation of circulating brain injury biomarker assessments into these pre-clinical studies suggests considerable potential for diagnostic and theranostic utility of glial fibrillary acidic protein in pre-clinical studies. Given the failures in clinical translation of therapies in TBI, rigorous multicenter, pre-clinical approaches to therapeutic screening such as OBTT may be important for the ultimate translation of therapies to the human condition.

    Controlled cortical impact (CCI) is a commonly used and highly regarded model of brain trauma that uses a pneumatically or electromagnetically controlled piston to induce reproducible and well-controlled injury. The CCI model was originally used in ferrets and it has since been scaled for use in many other species. This chapter will describe the historical development of the CCI model, compare and contrast the pneumatic and electromagnetic models, and summarize key short- and long-term consequences of TBI that have been gleaned using this model. In accordance with the recent efforts to promote high-quality evidence through the reporting of common data elements (CDEs), relevant study details-that should be reported in CCI studies-will be noted.

    The effects of intense noise exposure on the classical auditory pathway have been extensively investigated; however, little is known about the effects of noise-induced hearing loss on non-classical auditory areas in the brain such as the lateral amygdala (LA) and striatum (Str). To address this issue, we compared the noise-induced changes in spontaneous and tone-evoked responses from multiunit clusters (MUC) in the LA and Str with those seen in auditory cortex (AC) in rats. High-frequency octave band noise (10-20 kHz) and narrow band noise (16-20 kHz) induced permanent threshold shifts at high-frequencies within and above the noise band but not at low frequencies. While the noise trauma significantly elevated spontaneous discharge rate (SR) in the AC, SRs in the LA and Str were only slightly increased across all frequencies. The high-frequency noise trauma affected tone-evoked firing rates in frequency and time-dependent manner and the changes appeared to be related to the severity of noise trauma. In the LA, tone-evoked firing rates were reduced at the high-frequencies (trauma area) whereas firing rates were enhanced at the low-frequencies or at the edge-frequency dependent on severity of hearing loss at the high frequencies. The firing rate temporal profile changed from a broad plateau to one sharp, delayed peak. In the AC, tone-evoked firing rates were depressed at high frequencies and enhanced at the low frequencies while the firing rate temporal profiles became substantially broader. In contrast, firing rates in the Str were generally decreased and firing rate temporal profiles become more phasic and less prolonged. The altered firing rate and pattern at low frequencies induced by high-frequency hearing loss could have perceptual consequences. The tone-evoked hyperactivity in low-frequency MUC could manifest as hyperacusis whereas the discharge pattern changes could affect temporal resolution and integration. PMID:26701290

    Abstract Individuals 65 years of age and over have the highest rates of traumatic brain injury (TBI)-related hospitalizations and deaths, and older adults (defined variably across studies) have particularly poor outcomes after TBI. The factors predicting these outcomes remain poorly understood, and age-specific care guidelines for TBI do not exist. This study provides an overview of TBI in older adults using data from the National Trauma Data Bank (NTDB) gathered between 2007 and 2010, evaluates age group-specific trends in rates of TBI over time using U.S. Census data, and examines whether routinely collected information is able to predict hospital discharge status among older adults with TBI in the NTDB. Results showed a 20–25% increase in trauma center admissions for TBI among the oldest age groups (those >=75 years), relative to the general population, between 2007 and 2010. Older adults (>=65 years) with TBI tended to be white females who have incurred an injury from a fall resulting in a “severe” Abbreviated Injury Scale (AIS) score of the head. Older adults had more in-hospital procedures, such as neuroimaging and neurosurgery, tended to experience longer hospital stays, and were more likely to require continued medical care than younger adults. Older age, injury severity, and hypotension increased the odds of in-hospital death. The public health burden of TBI among older adults will likely increase as the Baby Boom generation ages. Improved primary and secondary prevention of TBI in this cohort is needed. PMID:23962046

  16. The brain's emotional foundations of human personality and the Affective Neuroscience Personality Scales.

    Six of the primary-process subcortical brain emotion systems - SEEKING, RAGE, FEAR, CARE, GRIEF and PLAY - are presented as foundational for human personality development, and hence as a potentially novel template for personality assessment as in the Affective Neurosciences Personality Scales (ANPS), described here. The ANPS was conceptualized as a potential clinical research tool, which would help experimentalists and clinicians situate subjects and clients in primary-process affective space. These emotion systems are reviewed in the context of a multi-tiered framing of consciousness spanning from primary affect, which encodes biological valences, to higher level tertiary (thought mediated) processing. Supporting neuroscience research is presented along with comparisons to Cloninger's Temperament and Character Inventory and the Five Factor Model (FFM). Suggestions are made for grounding the internal structure of the FFM on the primal emotional systems recognized in affective neuroscience, which may promote substantive dialog between human and animal research traditions. Personality is viewed in the context of Darwinian "continuity" with the inherited subcortical brain emotion systems being foundational, providing major forces for personality development in both humans and animals, and providing an affective infrastructure for an expanded five factor descriptive model applying to normal and clinical human populations as well as mammals generally. Links with ontogenetic and epigenetic models of personality development are also presented. Potential novel clinical applications of the CARE maternal-nurturance system and the PLAY system are also discussed.

    OBJECTIVE Sports-related traumatic brain injury (TBI) is an important public health concern estimated to affect 300,000 to 3.8 million people annually in the United States. Although injuries to professional athletes dominate the media, this group represents only a small proportion of the overall population. Here, the authors characterize the demographics of sports-related TBI in adults from a community-based trauma population and identify predictors of prolonged hospitalization and increased morbidity and mortality rates. METHODS Utilizing the National Sample Program of the National Trauma Data Bank (NTDB), the authors retrospectively analyzed sports-related TBI data from adults (age ≥ 18 years) across 5 sporting categories-fall or interpersonal contact (FIC), roller sports, skiing/snowboarding, equestrian sports, and aquatic sports. Multivariable regression analysis was used to identify predictors of prolonged hospital length of stay (LOS), medical complications, inpatient mortality rates, and hospital discharge disposition. Statistical significance was assessed at α < 0.05, and the Bonferroni correction for multiple comparisons was applied for each outcome analysis. RESULTS From 2003 to 2012, in total, 4788 adult sports-related TBIs were documented in the NTDB, which represented 18,310 incidents nationally. Equestrian sports were the greatest contributors to sports-related TBI (45.2%). Mild TBI represented nearly 86% of injuries overall. Mean (± SEM) LOSs in the hospital or intensive care unit (ICU) were 4.25 ± 0.09 days and 1.60 ± 0.06 days, respectively. The mortality rate was 3.0% across all patients, but was statistically higher in TBI from roller sports (4.1%) and aquatic sports (7.7%). Age, hypotension on admission to the emergency department (ED), and the severity of head and extracranial injuries were statistically significant predictors of prolonged hospital and ICU LOSs, medical complications, failure to discharge to home, and death.

    Background: Organ retrieval from brain dead patients is getting an increased attention as the waiting list for organ recipients far exceeds the organ donor pool. In our country, despite a large population the number of brain dead donors undergoing organ donation is very less (2% in our study). Aims: The present study was undertaken to address issues related to organ donation and share our experience for the same. Methods: A retrospective case record analysis of over 5 years from September 2007 to August 2012 was performed and the patients fulfilling brain death criterion as per Transplantation of Human Organs and Tissue (Amendment) Act were included. Patient demographics (age, sex), mode of injury, time from injury to the diagnosis of brain death, time from diagnosis of brain death to organ retrieval and complications were analysed. Statistics Analysis: Student's t test was used for parametric data and Chi square was used for categorical data. Results: Out of 205 patients who were identified as brain dead, only 10 patients became potential organ donors. Conclusion: Aggressive donor management, increasing public awareness about the concept of organ donation, good communication between clinician and the family members and a well-trained team of transplant coordinators can help in improving the number of organ donations.

    Cannabinoids form a singular family of plant-derived compounds (phytocannabinoids), endogenous signaling lipids (endocannabinoids), and synthetic derivatives with multiple biological effects and therapeutic applications in the central and peripheral nervous systems. One of these properties is the regulation of neuronal homeostasis and survival, which is the result of the combination of a myriad of effects addressed to preserve, rescue, repair, and/or replace neurons, and also glial cells against multiple insults that may potentially damage these cells. These effects are facilitated by the location of specific targets for the action of these compounds (e.g., cannabinoid type 1 and 2 receptors, endocannabinoid inactivating enzymes, and nonendocannabinoid targets) in key cellular substrates (e.g., neurons, glial cells, and neural progenitor cells). This potential is promising for acute and chronic neurodegenerative pathological conditions. In this review, we will collect all experimental evidence, mainly obtained at the preclinical level, supporting that different cannabinoid compounds may be neuroprotective in adult and neonatal ischemia, brain trauma, Alzheimer's disease, Parkinson's disease, Huntington's chorea, and amyotrophic lateral sclerosis. This increasing experimental evidence demands a prompt clinical validation of cannabinoid-based medicines for the treatment of all these disorders, which, at present, lack efficacious treatments for delaying/arresting disease progression, despite the fact that the few clinical trials conducted so far with these medicines have failed to demonstrate beneficial effects.

    A 16-year-old physically and mentally retarded male developed a complete Klüver-Bucy syndrome similar to that demonstrated in animal experiments and characterized by so-called psychic blindness, oral tendencies, hypermetamorphosis, emotional disturbance, and hypersexuality after severe brain trauma with loss of consciousness and a transitory hemiplegia. In addition, transitory oral and grasp reflexes were observed. Despite the severity of the clinical symptoms, the patient was able to realize and report on his subjective experience of the reflex and on the instinct-motivated behavior associated with the Klüver-Bucy syndrome. In the case described, two basic behavior patterns could be differentiated, each influencing drive and the abnormally increased sexuality. The first phase of the illness was dominated by relatively constant automatic reactions. These had the character of pre-determined instinctive behavior and were more or less emotionally neutral. In the second phase of the illness, the instinctive behavior became less evident and the patient was able to respond more normally to his sensory-motor impulses. Also, emotional experience such as frustration, pleasure, and displeasure regained their meaning for the patient.

    Since without prospective randomized studies it is not possible to have a clear attitude towards the importance of intracranial pressure monitoring, this study was aimed at examining the prognostic effect of the intracranial pressure monitoring and intracranial pressure oriented therapy in severe brain trauma patients, and at defining optimal intracranial pressure values for starting the treatment. Two groups of patients were treated in the study, one consisted of 32 patients undergoing intracranial pressure monitoring and the second group of 29 patients without intracranial pressure monitoring in the control group. The study was prospective with groups randomized. There were 53% survivals in the intracranial pressure monitored patients and 34% in the control group, with no significant difference in the survival rate between the two groups (chi2=2.11; p=0.15; p>0.05). The average intracranial pressure in the patients with intracranial hypertension who died was 27 mm Hg, while in the patients who survived the average intracranial pressure was significantly lower (Student's t test: t=2.91; p=0.008; p<0.01) and it was 18 mm Hg. We recommend starting intracranial pressure oriented therapy when the patient's intracranial pressure exceeds 18 mmHg during 2 hours of monitoring.

    Published information pertaining to the clinical utility of the WMS-III in assessing memory impairment in traumatic brain injury (TBI) remains inadequate. WMS-III findings are reported for 180 litigants with post-acute moderate to extremely severe TBI, classified into three groups according to injury severity, and a healthy control group. A significant "dose-response" relationship was found between memory impairment and TBI severity for most of the WMS-III indexes and subtests. Effect sizes were large for the Immediate and General Memory Indexes and medium for the Working Memory Index. In general, TBI had a greater effect on the Visual than Auditory Indexes. Effect sizes were greatest for Family Pictures and least for the auditory recognition and working memory tasks. Group findings indicate the immediate memory tasks to be clinically useful in relation to a severe or extremely severe TBI, but not for less severe trauma. Delayed memory tasks do not provide information additional to that obtained from immediate memory measures. The revised Tulsky indexes are no more sensitive to the effects of TBI than the original ones. Differences between WMS-III memory indexes are unlikely to be of diagnostic utility although memory-intelligence discrepancies may be.

    OBJECTIVE Traumatic brain injury (TBI) in children is a significant public health concern estimated to result in over 500,000 emergency department (ED) visits and more than 60,000 hospitalizations in the United States annually. Sports activities are one important mechanism leading to pediatric TBI. In this study, the authors characterize the demographics of sports-related TBI in the pediatric population and identify predictors of prolonged hospitalization and of increased morbidity and mortality rates. METHODS Utilizing the National Sample Program of the National Trauma Data Bank (NTDB), the authors retrospectively analyzed sports-related TBI data from children (age 0-17 years) across 5 sports categories: fall or interpersonal contact (FIC), roller sports, skiing/snowboarding, equestrian sports, and aquatic sports. Multivariable regression analysis was used to identify predictors of prolonged length of stay (LOS) in the hospital or intensive care unit (ICU), medical complications, inpatient mortality rates, and hospital discharge disposition. Statistical significance was assessed at α < 0.05, and the Bonferroni correction (set at significance threshold p = 0.01) for multiple comparisons was applied in each outcome analysis. RESULTS From 2003 to 2012, in total 3046 pediatric sports-related TBIs were recorded in the NTDB, and these injuries represented 11,614 incidents nationally after sample weighting. Fall or interpersonal contact events were the greatest contributors to sports-related TBI (47.4%). Mild TBI represented 87.1% of the injuries overall. Mean (± SEM) LOSs in the hospital and ICU were 2.68 ± 0.07 days and 2.73 ± 0.12 days, respectively. The overall mortality rate was 0.8%, and the prevalence of medical complications was 2.1% across all patients.

    The objective of this study was to determine the accuracy of individual radiologists in detection of vascular injury in patients after penetrating brain injury (PBI) based on head CT findings at admission. We retrospectively evaluated 54 PBI patients who underwent admission head CT and digital subtraction angiography (DSA), used here as a reference standard. Two readers reviewed the CT images to determine the presence or absence of the 29 CT variables of injury profile and quantified selected variables. Four experienced trauma radiologists and one neuroradiologist assigned their own specific scores for each CT variable, a high score indicative of a high probability of artery injury. A sixth set consisted of the average score obtained from the five sets, generated by five experts. Receiver operating characteristic (ROC) curves were constructed for each set to assess the diagnostic performance of an individual radiologist in predicting an underlying vascular injury. The area under ROC curve (AUC) was higher for CT scores obtained from the sixth set (average of five sets of scores) of variable rank score 0.75 (95% CI 0.62-0.88) and for the rest of the data sets, the value ranged from 0.70 (95% CI 0.56-0.84) to 0.74 (95% CI 0.6-0.88). In conclusion, radiologists may be able to recommend DSA with a fair accuracy rate in selected patients, deemed 'high-risk' for developing intracranial vascular injuries after PBI based on admission CT studies. A better approach needs to be developed to reduce the false positive rate to avoid unnecessary emergency DSA.

    Most studies of neuro-functional patterns in trauma-exposed individuals have been conducted considerable time after the traumatic event. Hence little is known about neuro-functional processing shortly after trauma-exposure. We investigated brain activity patterns in response to trauma reminders as well as neutral and negative stimuli in individuals who had recently (within 3 weeks) been involved in a road traffic accident (RTA). Twenty-three RTA survivors and 17 non-trauma-exposed healthy controls (HCs) underwent functional MRI while viewing Trauma-specific, Negative, and Neutral pictures. Data were analyzed from four a priori regions of interest, including bilateral amygdala, subcallosal cortex, and medial prefrontal cortex. In addition, we performed a whole brain analysis and functional connectivity analysis during stimulus presentation. For both groups, Negative stimuli elicited more activity in the amygdala bilaterally than did Neutral and Trauma-specific stimuli. The whole brain analysis revealed higher activation in sensory processing related areas (bilateral occipital and temporal cortices and thalamus) as well as frontal and superior parietal areas, for the RTA group compared to HC, for Trauma-specific stimuli contrasted with Neutral stimuli. We also observed higher functional connectivity for Trauma-specific stimuli, between bilateral amygdala and somatosensory areas, for the RTA group compared to controls, when contrasted with Neutral stimuli. We argue that these results might indicate an attentional sensory processing bias toward Trauma-specific stimuli for trauma exposed individuals, a result in line with findings from the post-traumatic stress disorder literature.

    Traumatic brain injury (TBI) induces a strong inflammatory response which includes blood-brain barrier damage, edema formation and infiltration of different immune cell subsets. More recently, microvascular thrombosis has been identified as another pathophysiological feature of TBI. The contact-kinin system represents an interface between inflammatory and thrombotic circuits and is activated in different neurological diseases. C1-Inhibitor counteracts activation of the contact-kinin system at multiple levels. We investigated the therapeutic potential of C1-Inhibitor in a model of TBI. Male and female C57BL/6 mice were subjected to cortical cryolesion and treated with C1-Inhibitor after 1 h. Lesion volumes were assessed between day 1 and day 5 and blood-brain barrier damage, thrombus formation as well as the local inflammatory response were determined post TBI. Treatment of male mice with 15.0 IU C1-Inhibitor, but not 7.5 IU, 1 h after cryolesion reduced lesion volumes by ~75% on day 1. This protective effect was preserved in female mice and at later stages of trauma. Mechanistically, C1-Inhibitor stabilized the blood-brain barrier and decreased the invasion of immune cells into the brain parenchyma. Moreover, C1-Inhibitor had strong antithrombotic effects. C1-Inhibitor represents a multifaceted anti-inflammatory and antithrombotic compound that prevents traumatic neurodegeneration in clinically meaningful settings. PMID:25249935

    Melatonin is an endogenous hormone mainly produced by the pineal gland whose dysfunction leads to abnormal sleeping patterns. Changes in melatonin have been reported in acute traumatic brain injury (TBI); however, the impact of environmental conditions typical of the intensive care unit (ICU) has not been assessed. The aim of this study was to compare daily melatonin production in three patient populations treated at the ICU to differentiate the role of TBI versus ICU conditions. Forty-five patients were recruited and divided into severe TBI, trauma without TBI, medical conditions without trauma, and compared to healthy volunteers. Serum melatonin levels were measured at four daily intervals at 0400 h, 1000 h, 1600 h, and 2200 h for 7 days post-ICU admission by commercial enzyme linked immunosorbent assay. The geometric mean concentrations (95% confidence intervals) of melatonin in these groups showed no difference being 8.3 (6.3–11.0), 9.3 (7.0–12.3), and 8.9 (6.6–11.9) pg/mL, respectively, in TBI, trauma, and intensive care cohorts. All of these patient groups demonstrated decreased melatonin concentrations when compared to control patients. This study suggests that TBI as well as ICU conditions, may have a role in the dysfunction of melatonin. Monitoring and possibly substituting melatonin acutely in these settings may assist in ameliorating long-term sleep dysfunction in all of these groups, and possibly contribute to reducing secondary brain injury in severe TBI.

    Vertebral artery (VA) injuries usually accompany cervical trauma. Although these injuries are commonly asymptomatic, some result in vertebrobasilar infarction. The symptoms of VA occlusion have been reported to usually manifest within 24 hours after trauma. The symptoms of bilateral VA occlusions seem to be more severe and seem to occur with shorter latencies than those of unilateral occlusions. A 48-year-old man had a C3-4 fracture-dislocation with spinal cord compression that resulted from a traffic accident. After surgery, his initial quadriparesis gradually improved. However, he complained of sudden headache and dizziness on the 5th postoperative day. His motor weakness was abruptly aggravated. Radiologic evaluation revealed an infarction in the occipital lobe and cerebellum. Cerebral angiography revealed complete bilateral VA occlusion. We administered anticoagulation therapy. After 6 months, his weakness had only partially improved. This case demonstrates that delayed infarction due to bilateral VA occlusion can occur at latencies as long as 5 days. Thus, we recommend that patients with cervical traumas that may be accompanied by bilateral VA occlusion should be closely observed for longer than 5 days.

    A large amount of brain-derived neurotrophic factor (BDNF) is stored in the human platelets and only small amounts of it circulate in the plasma. However, a few studies have focused on platelet BDNF in patients with major depressive disorder (MDD) and childhood trauma. Our study population consisted of 105 MDD patients and 50 healthy controls. We used the mini-international neuropsychiatric interview (M.I.N.I.), the early trauma inventory self report-short form (ETISR-SF), as well as measured serum, plasma, and platelet BDNF at baseline, 1 month, and 3 month periods. There was a significant association between childhood trauma and platelet BDNF at baseline, 1 month, and 3 months, after adjusting for age, gender, education, body mass index, severity of depression, anxiety, alcohol consumption, and current stress. Conversely, plasma and serum BDNF did not have a significant association with childhood trauma. MDD patients revealed significantly higher levels of platelet BDNF in those with childhood trauma than in those without (t = 2.4, p = 0.018), and platelet BDNF was significantly higher in cases with sexual abuse on post-hoc analysis (p = 0.042). However, no significant differences were found in healthy controls, according to whether or not they had experienced childhood trauma. Platelet BDNF showed a significant correlation with severity of childhood trauma at baseline (r = 0.25, p = 0.012) and at 3 months (r = 0.38, p = 0.003) in MDD. In conclusion, platelet BDNF was significantly higher in MDD patients with childhood trauma than in those without, and it was correlated with severity of trauma.

    It remains to be debated whether traumatic brain injury (TBI) induces a different coagulopathy than does non-TBI. This study investigated traditional coagulation tests, biomarkers of coagulopathy, and endothelial damage in trauma patients with and without TBI. Blood from 80 adult trauma patients was sampled (median of 68 min [IQR 48-88] post-injury) upon admission to our trauma center. Plasma/serum were retrospectively analyzed for biomarkers reflecting sympathoadrenal activation (adrenaline, noradrenaline), coagulation activation/inhibition and fibrinolysis (protein C, activated protein C, tissue factor pathway inhibitor, antithrombin, prothrombin fragment 1+2, thrombin/antithrombin complex, von Willebrand factor, factor XIII, d-dimer, tissue-type plasminogen activator, plasminogen activator inhibitor-1), immunology (interleukin [IL]6), endothelial cell/glycocalyx damage (soluble thrombomodulin, syndecan-1), and vasculogenesis (angiopoietin-1, -2). Patients were stratified according to: (1) isolated severe head/neck injuries (Abbreviated injury score [AIS]-head/neck ≥ 3, AIS-other<3) (isoTBI); (2) severe head/neck and extracranial injuries (AIS-head/neck ≥ 3, AIS-other>3) (sTBI+other); and (3) injuries without significant head/neck injuries (AIS-head/neck<3, including all AIS-other scores) (non-TBI). Twenty-three patients presented with isoTBI, 15 with sTBI+other and 42 with non-TBI. Acute coagulopathy of trauma shock, defined as activated partial thromboplastin time (APTT) and/or international normalized ratio (INR)>35 sec and>1.2, was found in 13%, 47%, and 5%, respectively (p=0.000). sTBI+other had significantly higher plasma levels of adrenaline, noradrenaline, annexin V, d-dimer, IL-6, syndecan-1, soluble thrombomodulin, and reduced protein C and factor XIII levels (all p<0.05). No significant biomarker differences were found between isoTBI and non-TBI patients. Injury severity scale (ISS) rather than the presence or absence of head/neck injuries

    High-pressure waves (blast) account for the majority of combat injuries and are becoming increasingly common in terrorist attacks. To our knowledge, there are no data evaluating the epidemiology of blast injury in a domestic nonterrorist setting. Data were analyzed retrospectively on patients admitted with any type of blast injury over a 10-year period at a busy urban trauma center. Injuries were classified by etiology of explosion and anatomical location. Eighty-nine cases of blast injury were identified in 57,392 patients (0.2%) treated over the study period. The majority of patients were male (78%) with a mean age of 40 +/- 17 years. The mean Injury Severity Score was 13 +/- 11 with an admission Trauma and Injury Severity Score of 0.9 +/- 0.2 and Revised Trauma Score of 7.5 +/- 0.8. The mean intensive care unit and hospital length of stay was 2 +/- 7 days and 4.6 +/- 10 days, respectively, with an overall mortality rate of 4.5 per cent. Private dwelling explosion [n = 31 (35%)] was the most common etiology followed by industrial pressure blast [n = 20 (22%)], industrial gas explosion [n = 16 (18%)], military training-related explosion [n = 15 (17%)], home explosive device [n = 8 (9%)], and fireworks explosion [n = 1 (1%)]. Maxillofacial injuries were the most common injury (n = 78) followed by upper extremity orthopedic (n = 29), head injury (n = 32), abdominal (n = 30), lower extremity orthopedic (n = 29), and thoracic (n = 19). The majority of patients with head injury [28 of 32 (88%)] presented with a Glasgow Coma Scale score of 15. CT scans on admission were initially positive for brain injury in 14 of 28 patients (50%). Seven patients (25%) who did not have a CT scan on admission had a CT performed later in their hospital course as a result of mental status change and were positive for traumatic brain injury (TBI). Three patients (11%) had a negative admission CT with a subsequently positive CT for TBI over the next 48 hours. The remaining four patients (14

    The presence of cerebral lesions in patients with neurosensory alterations provides a unique window into brain function. Using a fuzzy logic based combination of morphological information about 27 olfactory-eloquent brain regions acquired with four different brain imaging techniques, patterns of brain damage were analyzed in 127 patients who displayed anosmia, i.e., complete loss of the sense of smell (n = 81), or other and mechanistically still incompletely understood olfactory dysfunctions including parosmia, i.e., distorted perceptions of olfactory stimuli (n = 50), or phantosmia, i.e., olfactory hallucinations (n = 22). A higher prevalence of parosmia, and as a tendency also phantosmia, was observed in subjects with medium overall brain damage. Further analysis showed a lower frequency of lesions in the right temporal lobe in patients with parosmia than in patients without parosmia. This negative direction of the differences was unique for parosmia. In anosmia, and also in phantosmia, lesions were more frequent in patients displaying the respective symptoms than in those without these dysfunctions. In anosmic patients, lesions in the right olfactory bulb region were much more frequent than in patients with preserved sense of smell, whereas a higher frequency of carriers of lesions in the left frontal lobe was observed for phantosmia. We conclude that anosmia, and phantosmia, are the result of lost function in relevant brain areas whereas parosmia is more complex, requiring damaged and intact brain regions at the same time.

    Given that partial posttraumatic stress disorder (pPTSD) may be a specific risk factor for the development of posttraumatic stress disorder (PTSD), it is important to understand the neurobiology of pPTSD. However, there are few extant studies in this domain. Using resting-state functional magnetic resonance imaging (rs-fMRI) and a graph theoretical approach, we compared the topological organization of the whole-brain functional network in trauma-exposed firefighters with pPTSD (pPTSD group, n=9) with those without pPTSD (PC group, n=8) and non-traumatized healthy controls (HC group, n=11). We also examined changes in the network topology of five individuals with pPTSD before and after eye movement desensitization and reprocessing (EMDR) therapy. Individuals with pPTSD exhibited altered global properties, including a reduction in values of a normalized clustering coefficient, normalized local efficiency, and small-worldness. We also observed altered local properties, particularly in the association cortex, including the temporal and parietal cortices, across groups. These disruptive global and local network properties presented in pPTSD before treatment were ameliorated after treatment. Our preliminary results suggest that subthreshold manifestation of PTSD may be due to a disruption in the optimal balance in the functional brain networks and that this disruption can be ameliorated by psychotherapy.

    Traumatic brain injury (TBI) is a significant health concern classified as mild, moderate, and severe. Although the indications to perform brain computed tomography (CT) are clear in moderate and severe cases, there still exists controversy in mild TBI (mTBI). We designed the study to evaluate the significance of distracting pain in patients with mTBI. The study population included patients with mild traumatic brain injury (GCS ≥13). Moderate and high risk factors including age <18 months or ≥60 years, moderate to severe or progressive headache, ≥2 episodes of vomiting, loss of consciousness (LOC), post-traumatic amnesia, seizure or prior antiepileptic use, alcohol intoxication, previous neurosurgical procedures, uncontrolled hypertension, anticoagulant use, presence of focal neurologic deficits, deformities in craniofacial region, and penetrating injuries were excluded. The patients were then grouped based on presence (DP+) or absence (DP-) of another organ fracture with severe pain (based on VAS). The primary outcome was any abnormal findings on brain CT scans; 330 patients were enrolled (184 DP+ and 146 DP-). Overall, two DP+ and one DP- patients had mild cerebral edema in brain CT (p > 0.99). No patients had any neurologic symptoms or signs in follow-up. Our results show that in the absence of any other risk factors, distracting pain from other organs (limbs, pelvis, and non-cervical spine) cannot be regarded as a brain CT indication in patients with mild TBI, as it is never associated with significant intracranial lesions.

    We previously reported that intravenous (i.v.) administration of large volumes (0.2 ml/g) of either an isotonic dextrose-free solution or 5% dextrose solution given over 18 h after closed head trauma (CHT) in rats did not significantly affect neurological severity score or brain tissue specific gravity. However, it is possible that with more rapid administration, isotonic or 5% dextrose i.v. solutions may alter neurological outcome after CHT. Our study examined whether neurological severity score, brain tissue specific gravity and water content, and blood composition were significantly altered when 0.25 ml/g of either 0.9% saline or 5% dextrose was given i.v. over 0.5 h (rather than over 18 h) after CHT. Eight-four rats that survived ether anesthesia and CHT were randomly assigned to one of 11 experimental groups. Saline- and dextrose-treated rats were evaluated at 4 and 48 h after CHT and were compared to rats without CHT and to untreated rats at 4 and 48 h after CHT. There were no statistically significant differences in neurologic outcome and brain edema between the untreated and the saline-treated groups. However, 5% dextrose i.v. increased mortality (group 6 and 11, 50 and 0% survivors, respectively), decreased specific gravity in the noncontused hemisphere, and worsened neurologic outcome with and without CHT. Blood osmolality remained stable in comparison to the baseline value of 291.9 +/- 7.4 mOsm/kg (mean +/- SD).(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7881236

    Traumatic brain injury (TBI) increases susceptibility to Alzheimer's disease (AD), but it is not known if TBI affects the progression of AD. To address this question, we studied the neuropathological consequences of TBI in transgenic (TG) mice with a mutant human Abeta precursor protein (APP) mini-gene driven by a platelet-derived (PD) growth factor promoter resulting in overexpression of mutant APP (V717F), elevated brain Abeta levels, and AD-like amyloidosis. Since brain Abeta deposits first appear in 6-month-old TG (PDAPP) mice and accumulate with age, 2-year-old PDAPP and wild-type (WT) mice were subjected to controlled cortical impact (CCI) TBI or sham treatment. At 1, 9, and 16 weeks after TBI, neuron loss, gliosis, and atrophy were most prominent near the CCI site in PDAPP and WT mice. However, there also was a remarkable regression in the Abeta amyloid plaque burden in the hippocampus ipsilateral to TBI compared to the contralateral hippocampus of the PDAPP mice by 16 weeks postinjury. Thus, these data suggest that previously accumulated Abeta plaques resulting from progressive amyloidosis in the AD brain also may be reversible. PMID:10785464

    Magnetic resonance imaging enables the noninvasive mapping of both anatomical white matter connectivity and dynamic patterns of neural activity in the human brain. We examine the relationship between the structural properties of white matter streamlines (structural connectivity) and the functional properties of correlations in neural activity (functional connectivity) within 84 healthy human subjects both at rest and during the performance of attention- and memory-demanding tasks. We show that structural properties, including the length, number, and spatial location of white matter streamlines, are indicative of and can be inferred from the strength of resting-state and task-based functional correlations between brain regions. These results, which are both representative of the entire set of subjects and consistently observed within individual subjects, uncover robust links between structural and functional connectivity in the human brain.

    Patients with severe craniocerebral trauma (sCCT) display metabolic and endocrine changes. The question is raised whether hormonal patterns give cues to the prognosis of outcome or not. In 21 patients the function of the adrenocortical, gonadal, thyroid and human growth hormone (hGH)-insulin system was assessed. LH, FSH, TSH, prolactin and hGH were stimulated. 3 groups of patients were formed. Group I: patients in acute phase with a Glasgow Coma Score (GCS) more than 6 (group Ia) and less than 6 (group Ib). Group II: patients in transition to traumatic apallic syndrome (TAS). Group III: patients with full-blown or resolving TAS. The values of group Ia comprised low T3, T4 and testosterone, elevated insulin, normal hGH. Group Ib had hypothyroid T3 and T4 and an attenuated response of LH, TSH, prolactin and hGH to stimulation. Group III: there was seen an endocrine normalisation with elevated T4 and TBG and an altered response of hGH and prolactin to stimulation. Endocrine abnormalities were not helpful in predicting which course, either to better or to worse, a given patient would follow.

    The detrimental effects of traumatic brain injury (TBI) on brain tissue integrity involve progressive axonal damage, necrotic cell loss, and both acute and delayed apoptotic neuronal death due to activation of caspases. Post-injury accumulation of amyloid precursor protein (APP) and its toxic metabolite amyloid-beta peptide (Abeta) has been implicated in apoptosis as well as in increasing the risk for developing Alzheimer's disease (AD) after TBI. Activated caspases proteolyze APP and are associated with increased Abeta production after neuronal injury. Conversely, Abeta and related APP/Abeta fragments stimulate caspase activation, creating a potential vicious cycle of secondary injury after TBI. Blockade of caspase activation after brain injury suppresses apoptosis and improves neurological outcome, but it is not known whether such intervention also prevents increases in Abeta levels in vivo. The present study examined the effect of caspase inhibition on post-injury levels of soluble Abeta, APP, activated caspase-3, and caspase-cleaved APP in the hippocampus of nontransgenic mice expressing human Abeta, subjected to controlled cortical injury (CCI). CCI produced brain tissue damage with cell loss and elevated levels of activated caspase-3, Abeta(1-42) and Abeta(1-40), APP, and caspase-cleaved APP fragments in hippocampal neurons and axons. Post-CCI intervention with intracerebroventricular injection of 100 nM Boc-Asp(OMe)-CH(2)F (BAF, a pan-caspase inhibitor) significantly reduced caspase-3 activation and improved histological outcome, suppressed increases in Abeta and caspase-cleaved APP, but showed no significant effect on overall APP levels in the hippocampus after CCI. These data demonstrate that after TBI, caspase inhibition can suppress elevations in Abeta. The extent to which Abeta suppression contributes to improved outcome following inhibition of caspases after TBI is unclear, but such intervention may be a valuable therapeutic strategy for preventing the

    Recent in vitro studies showed that stem cells might fuse with mature cells or each other; however, there is no in vivo evidence for this phenomenon in the cerebral cortex. Our goal was to find evidence for cell fusion in a model of traumatic brain injury followed by grafting of embryonic cortical cells. Cold lesion protocol was applied to induce lesion of the motor cortex in adult male rats. Six days later we grafted a suspension of freshly isolated rat brain cortical cells of early embryonic stage (E14) into the penumbra area of the lesion. The grafted cell nuclei were labelled with bromodeoxyuridine (BrDU). Six days after transplantation 4,328 BrDU positive cells were observed in nine animals. 89.5% of these cells had cytoplasmic staining probably representing dead or phagocyted grafted cells. Ten percent of surviving BrDU positive cells had only one BrDU positive nucleus and negative cytoplasm, while 0.5% had two distinct nuclei, one was unlabelled and one was BrDU positive. These cells were similar in appearance and size to the astrocytes in the vicinity and expressed the astocyte specific glial fibrillaly acidic protein. Thus, these cells showed a possible sign of cell fusion in the penumbral region of the injured brain. PMID:16377084

    We previously demonstrated that after traumatic brain injury (TBI), acute progesterone withdrawal (AW) causes an increase in anxiety behaviors and cerebro-cellular inflammation compared to tapered progesterone withdrawal (TW). Our current study investigates the behavioral and cellular effects of AW two weeks after termination of treatments to determine the longer-term influence of withdrawal after injury. Adult, male Sprague-Dawley rats received either bilateral frontal cortex contusion (L) or sham (S) surgery. Rats were injected at 1 and 6 h post-injury, then every 24 h for six days. Vehicle (V)-treated rats were given 9 injections of 22.5% cyclodextrin, whereas AW rats received 9 injections of 16 mg/kg progesterone and TW rats received 7 injections of P at 16 mg/kg, followed by one at 8 mg/kg and one at 4 mg/kg. On day 8, sensory neglect and locomotor activity tests were initiated. Animals were killed 22 days post-TBI and the brains prepared for either molecular or histological analysis. Western blotting revealed increased brain-derived neurotrophic factor (BDNF) and heat shock protein 70 (HSP70) in TW vs. AW animals. P53 was increased in VL animals, whereas all progesterone-treated groups were equivalent to shams. TW animals had markedly decreased sensory neglect compared to AW animals and increased center time in locomotor activity assays. In addition, lesion reconstruction revealed a decreased lesion size for TWL over AWL over VL animals. Glial fibrillary acidic protein (GFAP) immunofluorescent staining followed this pattern as well. In conclusion, after TBI, AW affects select behaviors and molecular markers in the chronic recovery period. PMID:16797538

    Sexual aggression can disrupt processes related to learning as females emerge from puberty into young adulthood. To model these experiences in laboratory studies, we developed SCAR, which stands for Sexual Conspecific Aggressive Response. During puberty, a rodent female is paired daily for 30-min with a sexually-experienced adult male. During the SCAR experience, the male tracks the anogenital region of the female as she escapes from pins. Concentrations of the stress hormone corticosterone were significantly elevated during and after the experience. Moreover, females that were exposed to the adult male throughout puberty did not perform well during training with an associative learning task nor did they learn well to express maternal behaviors during maternal sensitization. Most females that were exposed to the adult male did not learn to care for offspring over the course of 17 days. Finally, females that did not express maternal behaviors retained fewer newly-generated cells in their hippocampus whereas those that did express maternal behaviors retained more cells, most of which would differentiate into neurons within weeks. Together these data support SCAR as a useful laboratory model for studying the potential consequences of sexual aggression and trauma for the female brain during puberty and young adulthood.

    Technology brain-computer interface (BCI) based on the registration and interpretation of EEG has recently become one of the most popular developments in neuroscience and psychophysiology. This is due not only to the intended future use of these technologies in many areas of practical human activity, but also to the fact that IMC--is a completely new paradigm in psychophysiology, allowing test hypotheses about the possibilities of the human brain to the development of skills of interaction with the outside world without the mediation of the motor system, i.e. only with the help of voluntary modulation of EEG generators. This paper examines the theoretical and experimental basis, the current state and prospects of development of training, communicational and assisting complexes based on BCI to control them without muscular effort on the basis of mental commands detected in the EEG of patients with severely impaired speech and motor system.

    The goal of these experiments was to evaluate the effects of some drugs affecting noradrenergic (NE) synaptic transmission, commonly prescribed following stroke or traumatic brain injury, on functional recovery. Measurement of recovery from a transient hemiplegia produced by a traumatic unilateral focal contusion in sensorimotor cortex (SMCX) of rats was used to assess the effects of chronic haloperidol (HAL) treatment begun early (1 day) or late (18 days to recovered animals) after injury. Additionally, using the same model, the effects of a single administration of drugs with selective action at NE receptors were also evaluated early or late (30 days) after injury. These drugs were: phenoxybenzamine (PBZ), an alpha 1-NE antagonist; prazosin (PRAZ), an alpha 1-NE antagonist; yohimbine (YOH), an alpha 2-NE antagonist; propranolol (PROP), a beta 1- and 2-NE receptor antagonist; methoxymine (METHOX), an alpha 1-NE agonist; and clonidine (CLON), an alpha 2-NE agonist. The data indicate that drugs with antagonistic effects at alpha 1 NE receptors, including HAL and PRAZ but not PROP, administered early after SMCX contusion retard locomotor recovery. Beneficial effects of enhancing NE transmission by METHOX or YOH were not observed. In animals recovered from beam walk (BW) deficits, a single administration of PBZ or PRAZ (alpha 1 NE antagonists) or CLON (alpha 2 NE agonist) transiently reinstated hemiplegic symptoms. The nonspecific beta NE receptor antagonist PROP had no effect in recovered animals. A single dose of HAL had no effect in recovered animals, but a BW deficit transiently developed in some animals following chronic treatment. The data are discussed with reference to drug contraindications noted in clinical studies of recovery from poststroke aphasia and cognition in demented patients with degenerative brain disease.

    Purpose: Application of cone-beam CT (CBCT) to low-contrast soft tissue imaging, such as in detection of traumatic brain injury, is challenged by high levels of scatter. A fast, accurate scatter correction method based on Monte Carlo (MC) estimation is developed for application in high-quality CBCT imaging of acute brain injury. Methods: The correction involves MC scatter estimation executed on an NVIDIA GTX 780 GPU (MC-GPU), with baseline simulation speed of ~1e7 photons/sec. MC-GPU is accelerated by a novel, GPU-optimized implementation of variance reduction (VR) techniques (forced detection and photon splitting). The number of simulated tracks and projections is reduced for additional speed-up. Residual noise is removed and the missing scatter projections are estimated via kernel smoothing (KS) in projection plane and across gantry angles. The method is assessed using CBCT images of a head phantom presenting a realistic simulation of fresh intracranial hemorrhage (100 kVp, 180 mAs, 720 projections, source-detector distance 700 mm, source-axis distance 480 mm). Results: For a fixed run-time of ~1 sec/projection, GPU-optimized VR reduces the noise in MC-GPU scatter estimates by a factor of 4. For scatter correction, MC-GPU with VR is executed with 4-fold angular downsampling and 1e5 photons/projection, yielding 3.5 minute run-time per scan, and de-noised with optimized KS. Corrected CBCT images demonstrate uniformity improvement of 18 HU and contrast improvement of 26 HU compared to no correction, and a 52% increase in contrast-tonoise ratio in simulated hemorrhage compared to “oracle” constant fraction correction. Conclusion: Acceleration of MC-GPU achieved through GPU-optimized variance reduction and kernel smoothing yields an efficient (<5 min/scan) and accurate scatter correction that does not rely on additional hardware or simplifying assumptions about the scatter distribution. The method is undergoing implementation in a novel CBCT dedicated to brain

    Objective The aims of the Korean Neuro-Trauma Data Bank System (KNTDBS) are to evaluate and improve treatment outcomes for brain trauma, prevent trauma, and provide data for research. Our purpose was to examine the mortality rates following traumatic brain injury (TBI) in a retrospective study and to investigate the sociodemographic variables, characteristics, and causes of TBI-related death based on data from the KNTDBS. Methods From 2010 to 2014, we analyzed the data of 2617 patients registered in the KNTDBS. The demographic characteristics of patients with TBI were investigated. We divided patients into 2 groups, survivors and nonsurvivors, and compared variables between the groups to investigate variables that are related to death after TBI. We also analyzed variables related to the interval between TBI and death, mortality by region, and cause of death in the nonsurvivor group. Results The frequency of TBI in men was higher than that in women. With increasing age of the patients, the incidence of TBI also increased. Among 2617 patients, 688 patients (26.2%) underwent surgical treatment and 125 patients (4.7%) died. The age distributions of survivors vs. nonsurvivor groups and mortality rates according the severity of the brain injury, surgical treatment, and initial Glasgow Coma Scale (GCS) scores were statistically significantly different. Among 125 hospitalized nonsurvivors, 70 patients (56%) died within 7 days and direct brain damage was the most common cause of death (80.8%). The time interval from TBI to death differed depending on the diagnosis, surgical or nonsurgical treatment, severity of brain injury, initial GCS score, and cause of death, and this difference was statistically significant. Conclusion Using the KNTDBS, we identified epidemiology, mortality, and various factors related to nonsurvival. Building on our study, we should make a conscious effort to increase the survival duration and provide rapid and adequate treatment for TBI patients

    Traumatic injury/hemorrhagic shock (T/HS) elicits an acute inflammatory response that may result in death. Inflammation describes a coordinated series of molecular, cellular, tissue, organ, and systemic responses that drive the pathology of various diseases including T/HS and traumatic brain injury (TBI). Inflammation is a finely tuned, dynamic, highly-regulated process that is not inherently detrimental, but rather required for immune surveillance, optimal post-injury tissue repair, and regeneration. The inflammatory response is driven by cytokines and chemokines and is partially propagated by damaged tissue-derived products (Damage-associated Molecular Patterns; DAMP's). DAMPs perpetuate inflammation through the release of pro-inflammatory cytokines, but may also inhibit anti-inflammatory cytokines. Various animal models of T/HS in mice, rats, pigs, dogs, and non-human primates have been utilized in an attempt to move from bench to bedside. Novel approaches, including those from the field of systems biology, may yield therapeutic breakthroughs in T/HS and TBI in the near future. PMID:21483522

    Traumatic brain injury (TBI) from penetrating or closed forces to the cranium can result in a range of forms of neural damage, which culminate in mortality or impart mild to significant neurological disability. In this regard, diffuse axonal injury (DAI) is a major neuronal pathophenotype of TBI and is associated with a complex set of cytoskeletal changes. The neurofilament triplet proteins are key structural cytoskeletal elements, which may also be important contributors to the tensile strength of axons. This has significant implications with respect to how axons may respond to TBI. It is not known, however, whether neurofilament compaction and the cytoskeletal changes that evolve following axonal injury represent a component of a protective mechanism following damage, or whether they serve to augment degeneration and progression to secondary axotomy. Here we review the structure and role of neurofilament proteins in normal neuronal function. We also discuss the processes that characterize DAI and the resultant alterations in neurofilaments, highlighting potential clues to a possible protective or degenerative influence of specific neurofilament alterations within injured neurons. The potential utility of neurofilament assays as biomarkers for axonal injury is also discussed. Insights into the complex alterations in neurofilaments will contribute to future efforts in developing therapeutic strategies to prevent, ameliorate or reverse neuronal degeneration in the central nervous system (CNS) following traumatic injury.

    The goal of this study is to reintegrate the theory of generative grammar into the cognitive sciences. Generative grammar was right to focus on the child's acquisition of language as its central problem, leading to the hypothesis of an innate Universal Grammar. However, generative grammar was mistaken in assuming that the syntactic component is the sole course of combinatoriality, and that everything else is "interpretive." The proper approach is a parallel architecture, in which phonology, syntax, and semantics are autonomous generative systems linked by interface components. The parallel architecture leads to an integration within linguistics, and to a far better integration with the rest of cognitive neuroscience. It fits naturally into the larger architecture of the mind/brain and permits a properly mentalistic theory of semantics. It results in a view of linguistic performance in which the rules of grammar are directly involved in processing. Finally, it leads to a natural account of the incremental evolution of the language capacity.

    Deficits in white matter (WM) integrity occur following traumatic brain injury (TBI), and often persist long after the visible scars have healed. Heterogeneity in injury types and locations can complicate analyses, making it harder to discover common biomarkers for tracking recovery. Here we apply a newly developed adaptive connectivity method, EPIC (evolving partitions to improve connectomics) to identify differences in structural connectivity that persist longitudinally. This data comes from a longitudinal study, in which we scanned participants (aged 8-19 years) with anatomical and diffusion MRI in both the post-acute and chronic phases (1-6 months and 13-19 months post-injury). To identify patterns of abnormal connectivity, we trained a model on data from 32 TBI patients in the post-acute phase and 45 well-matched healthy controls, reducing an initial 68x68 connectivity matrix to a 14x14 matrix. We then applied this reduced parcellation to the chronic data in participants who had returned for their chronic assessment (21 TBI and 26 healthy controls) and tested for group differences. We found significant differences in two connections, comprising callosal fibers and long anterior-posterior fibers, with the TBI group showing increased fiber density relative to controls. Longitudinal analysis revealed that these were connections that were decreasing over time in the healthy controls, as is a common developmental phenomenon, but they were increasing in the TBI group. While we cannot definitively tell why this may occur with our current data, this study provides targets for longitudinal tracking, and poses questions for future investigation.

    Abstract Clinical research into outcomes after traumatic brain injury (TBI) frequently combines injuries that have been sustained through different causes (e.g., car accidents, assaults, and falls), the effect of which is not well understood. This study examined the contribution of injury-related psychological trauma—which is more commonly associated with specific types of injuries—to outcomes after nonpenetrating TBI in order to determine whether it may be having a differential effect in samples containing mixed injuries. Data from three groups that were prospectively recruited for two larger studies were compared: one that sustained a TBI as a result of physical assaults (i.e., psychologically traumatizing) and another as a result of sporting injuries (i.e., nonpsychologically traumatizing), as well as an orthopedic control group (OC). Psychosocial and emotional (postconcussion symptoms, injury-related stress, and depression), cognitive (memory, abstract reasoning, problem solving, and verbal fluency), and functional (general outcome; resumption of home, social, and work roles) outcomes were all assessed. The TBIassault group reported significantly poorer psychosocial and emotional outcomes and higher rates of litigation (criminal rather than civil) than both the TBIsport and OC groups approximately 6 months postinjury, but there were no differences in the cognitive or functional outcomes of the three groups. The findings suggest that the cause of a TBI may assist in explaining some of the differences in outcomes of people who have seemingly comparable injuries. Involvement in litigation and the cause of an injury may also be confounded, which may lead to the erroneous conclusion that litigants have poorer outcomes. PMID:24228916

    Introduction: Traumatic brain injury (TBI) is a leading cause of mortality, morbidity, disability, and socioeconomic losses in the Indian subcontinent. However, for policymaking and research, there is a lack of reliable and larger data in our settings. Aims and Objectives: To evaluate and describe the epidemiological, clinical characteristics, and outcomes of patients with TBI in a Level 1 Trauma Center in India. Materials and Methods: In this retrospective study, all patients with moderate or severe TBI, based on emergency department Glasgow Coma Scale, admitted to neurosurgery Intensive Care Unit (ICU) during May 2010–July 2012 were evaluated to provide detailed information on TBI-related variables and outcomes using descriptive statistics. Results: Among the 1527 patients with moderate or severe TBI patients with mean age 32.15 ± 16.76 years (range: 1–90) and male:female ratio 6.5:1, 1281 (83.89%) had severe TBI. The majority of cases took place in the age group of 21–40 years (50.24%) with the most common mode of injury as road traffic accidents (RTAs) (64.96%). Surgical intervention (craniotomy) was done in 49.12% of patients. About 34.58% (n = 528) patients died in hospital, and 67.21% (n = 701) had unfavorable outcome at 6 months. Conclusions: This is the first study of its kind from the Indian subcontinent that gives data on the admission characteristics, mortality, and 6 months outcome of such patients. Most of the injuries occurred due to RTAs, more common among the economic productive age groups and mostly in males with a high rate of mortality and unfavorable outcome. PMID:27695230

    A short cut review was carried out to establish whether ketamine is a viable induction agent in trauma patients with potential brain injuries. 276 papers were found using the reported searches, of which 5 presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that there is no evidence to suggest harm with Ketamine use as induction agent for the patient with potential traumatic brain injury. The drug has major advantages in those patients with associated haemodynamic compromise and should potentially be regarded as the agent of choice.

    The neurovascular unit provides a dynamic interface between the circulation and central nervous system. Disruption of neurovascular integrity occurs in numerous brain pathologies including neurotrauma and ischaemic stroke. Tissue plasminogen activator is a serine protease that converts plasminogen to plasmin, a protease that dissolves blood clots. Besides its role in fibrinolysis, tissue plasminogen activator is abundantly expressed in the brain where it mediates extracellular proteolysis. However, proteolytically active tissue plasminogen activator also promotes neurovascular disruption after ischaemic stroke; the molecular mechanisms of this process are still unclear. Tissue plasminogen activator is naturally inhibited by serine protease inhibitors (serpins): plasminogen activator inhibitor-1, neuroserpin or protease nexin-1 that results in the formation of serpin:protease complexes. Proteases and serpin:protease complexes are cleared through high-affinity binding to low-density lipoprotein receptors, but their binding to these receptors can also transmit extracellular signals across the plasma membrane. The matrix metalloproteinases are the second major proteolytic system in the mammalian brain, and like tissue plasminogen activators are pivotal to neurological function but can also degrade structures of the neurovascular unit after injury. Herein, we show that tissue plasminogen activator potentiates neurovascular damage in a dose-dependent manner in a mouse model of neurotrauma. Surprisingly, inhibition of activity following administration of plasminogen activator inhibitor-1 significantly increased cerebrovascular permeability. This led to our finding that formation of complexes between tissue plasminogen activator and plasminogen activator inhibitor-1 in the brain parenchyma facilitates post-traumatic cerebrovascular damage. We demonstrate that following trauma, the complex binds to low-density lipoprotein receptors, triggering the induction of matrix

    Imaging is an indispensable part of the initial assessment and subsequent management of patients with head trauma. Initially, it is important for diagnosing the extent of injury and the prompt recognition of treatable injuries to reduce mortality. Subsequently, imaging is useful in following the sequelae of trauma. In this chapter, we review indications for neuroimaging and typical computed tomography (CT) and magnetic resonance imaging (MRI) protocols used in the evaluation of a patient with head trauma. We review the role of CT), the imaging modality of choice in the acute setting, and the role of MRI in the evaluation of patients with head trauma. We describe an organized and consistent approach to the interpretation of imaging of these patients. Important topics in head trauma, including fundamental concepts related to skull fractures, intracranial hemorrhage, parenchymal injury, penetrating trauma, cerebrovascular injuries, and secondary effects of trauma, are reviewed. The chapter concludes with advanced neuroimaging techniques for the evaluation of traumatic brain injury, including use of diffusion tensor imaging (DTI), functional MRI (fMRI), and MR spectroscopy (MRS), techniques which are still under development.

External ear trauma (ie, hematoma or laceration) should be promptly treated with appropriate injury-specific techniques. Tympanic membrane injuries have multiple mechanisms and can often be conservatively treated. Temporal bone fractures are a common cause of ear trauma and can be life threatening.

As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

    Mannino and Bressler [1] discuss foundational issues related to understating causality in a complex system such as the brain. We largely agree with their main point that standard versions of causality, such as those espoused in classical physics, provide an inadequate basis to support the understanding of complex systems. In a nutshell, instead of thinking that one event causes another, it is more fruitful to think that the occurrence of one event changes the probability of occurrence of other events. Such probabilistic notion of causation is, we believe, an important step in attempting to unravel the workings of the brain.

    Traumatic brain injury (TBI) is a major medical and socio-economic problem, and is the leading cause of death in children and young adults. The critical care management of severe TBI is largely derived from the "Guidelines for the Management of Severe Traumatic Brain Injury" that have been published by the Brain Trauma Foundation. The main objectives are prevention and treatment of intracranial hypertension and secondary brain insults, preservation of cerebral perfusion pressure (CPP), and optimization of cerebral oxygenation. In this review, the critical care management of severe TBI will be discussed with focus on monitoring, avoidance and minimization of secondary brain insults, and optimization of cerebral oxygenation and CPP.

    Shock-wave exposure from improvised explosive devices (IEDs) has been implicated as a possible contributing factor to neurological impairment reported in combat veterans. However, evidence-based substantiation of this implication, particularly for low-level exposure in the absence of external signs of trauma, remain elusive. Accordingly, we constructed an open-ended shock tube producing a short-duration, low-amplitude shockwave. Low-level (11.5 kPa static overpressure) complex shock-wave exposure in rats resulted in no histological evidence of lung injury. By contrast, delayed cytoskeletal proteolysis of αII-spectrin was detected in the cortex and hippocampus by 12 h post-injury. Cell death was minimal and localized predominantly in the corpus callosum and periventricular regions. These regions, with presumably different density interfaces, exhibit biological responses to shockwaves consistent with interface turbulence described by Richtmyer-Meshkov instability. Evoked compound action potential (CAP) recordings from the corpus callosum showed a significant increase in the duration of CAP responses at 14 and 30 days post-injury, and a gradual depression in the unmyelinated fiber amplitude. Shielding the head attenuated αII-spectrin cytoskeletal breakdown, thus directly implicating low-level shock-wave exposure as a cause of brain injury in the rat. Despite anatomical and scaling differences in rats compared to humans, the results suggest the potential for undiagnosed traumatic brain pathologies occurring in combat veterans following shock-wave exposure.

    The X-ray repair cross-complementing group 1 (XRCC1) protein plays a central role in the DNA base excision repair pathway by interacting with DNA ligase III and DNA polymerase beta. The present study examined the protein expression of XRCC1 and DNA fragmentation before and after cold injury-induced brain trauma (CIBT) in mice, in which apoptosis is assumed to participate. Immunohistochemistry showed the nuclear expression of XRCC1 in the entire region of the control brains. Fifteen minutes after CIBT, nuclear immunoreactivity was predominantly decreased in the inner boundary of the lesion, followed by a significant reduction of XRCC1 in the entire lesion 4 h after CIBT. A characteristic 70-kDa band was detected in the non-traumatic area, and was markedly decreased after CIBT as shown by Western blot analysis. DNA fragmentation was also observed after CIBT, and double staining with XRCC1 immunohistochemistry and terminal deoxynucleotidyl transferase-mediated uridine 5'-triphosphate-biotin nick end labeling showed a spatial relationship between XRCC1 loss and DNA fragmentation 24 h after CIBT. These data indicate that early decrease of XRCC1 and failure of the DNA repair mechanism may contribute to DNA-damaged neuronal cell death after CIBT.

    Penetrating gunshot injuries to the head and brain are rare in Germany and the rest of Western Europe. Due to the small number of cases over here no consistent diagnostic and therapeutic standards exist in this respect. Thus these kinds of injuries present a great challenge to the attending physicians. Most of these violations are a result of a suicidal attempt or an accident. Beside violations by firearms also penetrating injuries to the head and brain due to captive bolt devices, as used in slaughtery business for the "humane" killing of animals, occur from time to time. The impact on the head differs from that caused by firearms because no projectile is leaving the barrel and the used bolt, as a fix part of the device, does not remain in the affected tissue. That implies characteristic results within the radiological imaging that might be pathbreaking for the further treatment, because the origin of such a head injury is often unknown during primary care. Consequently the knowledge of these specific findings is central to the radiologist to make the appropriate diagnosis. Based on some clinical examples the trauma-related CT-findings are introduced and a short overview of the relevant literature is also given.

    ABSTRACT Trauma is a leading cause of death in both military and civilian populations worldwide. Although medical advances have improved the overall morbidity and mortality often associated with trauma, additional research and innovative advancements in therapeutic interventions are needed to optimize patient outcomes. Cell-based therapies present a novel opportunity to improve trauma and critical care at both the acute and chronic phases that often follow injury. Although this field is still in its infancy, animal and human studies suggest that stem cells may hold great promise for the treatment of brain and spinal cord injuries, organ injuries, and extremity injuries such as those caused by orthopedic trauma, burns, and critical limb ischemia. However, barriers in the translation of cell therapies that include regulatory obstacles, challenges in manufacturing and clinical trial design, and a lack of funding are critical areas in need of development. In 2015, the Department of Defense Combat Casualty Care Research Program held a joint military–civilian meeting as part of its effort to inform the research community about this field and allow for effective planning and programmatic decisions regarding research and development. The objective of this article is to provide a “state of the science” review regarding cellular therapies in trauma and critical care, and to provide a foundation from which the potential of this emerging field can be harnessed to mitigate outcomes in critically ill trauma patients.

    Unraveling the dynamically changing networks of the brain is probably the single most important current task for the neurosciences. I wish to commend the authors on this refreshing and provocative paper [1], which not only recapitulates some of the longstanding philosophical difficulties involved in the analysis of causality in the sciences, but also summarizes current work on statistical methods for determining causal networks in the brain. I fully concur with several of the opinions defended by the authors: The most fruitful level of analysis for systems neuroscience is that of neural masses, each comprising thousands of neurons. This is what is known as the mesoscopic scale.

  9. Chronic traumatic encephalopathy: a spectrum of neuropathological changes following repetitive brain trauma in athletes and military personnel

    PubMed Central

    2014-01-01

    Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disease that occurs in association with repetitive traumatic brain injury experienced in sport and military service. In most instances, the clinical symptoms of the disease begin after a long period of latency ranging from several years to several decades. The initial symptoms are typically insidious, consisting of irritability, impulsivity, aggression, depression, short-term memory loss and heightened suicidality. The symptoms progress slowly over decades to include cognitive deficits and dementia. The pathology of CTE is characterized by the accumulation of phosphorylated tau protein in neurons and astrocytes in a pattern that is unique from other tauopathies, including Alzheimer’s disease. The hyperphosphorylated tau abnormalities begin focally, as perivascular neurofibrillary tangles and neurites at the depths of the cerebral sulci, and then spread to involve superficial layers of adjacent cortex before becoming a widespread degeneration affecting medial temporal lobe structures, diencephalon and brainstem. Most instances of CTE (>85% of cases) show abnormal accumulations of phosphorylated 43 kDa TAR DNA binding protein that are partially colocalized with phosphorylated tau protein. As CTE is characterized pathologically by frontal and temporal lobe atrophy, by abnormal deposits of phosphorylated tau and by 43 kDa TAR DNA binding protein and is associated clinically with behavioral and personality changes, as well as cognitive impairments, CTE is increasingly categorized as an acquired frontotemporal lobar degeneration. Currently, some of the greatest challenges are that CTE cannot be diagnosed during life and the incidence and prevalence of the disorder remain uncertain. Furthermore, the contribution of age, gender, genetics, stress, alcohol and substance abuse to the development of CTE remains to be determined. PMID:24423082

    Ultrasound plays a pivotal role in the evaluation of acute trauma patients through the use of multi-site scanning encompassing abdominal, cardiothoracic, vascular and skeletal scans. In a high-speed polytrauma setting, because exsanguinations are the primary cause of trauma morbidity and mortality, ultrasound is used for quick and accurate detection of hemorrhages in the pericardial, pleural, and peritoneal cavities during the primary Advanced Trauma Life Support (ATLS) survey. Volume status can be assessed non-invasively with ultrasound of the inferior vena cava (IVC), which is a useful tool in the initial phase and follow-up evaluations. Pneumothorax can also be quickly detected with ultrasound. During the secondary survey and in patients sustaining low-speed or localized trauma, ultrasound can be used to help detect abdominal organ injuries. This is particularly helpful in patients in whom hemoperitoneum is not identified on an initial scan because findings of organ injuries will expedite the next test, often computed tomography (CT). Moreover, ultrasound can assist in detection of fractures easily obscured on radiography, such as rib and sternal fractures.

    Lung injury in trauma patients can occur because of direct injury to lung or due to secondary effects of injury elsewhere for example fat embolism from a long bone fracture, or due to response to a systemic insult such as; acute respiratory distress syndrome (ARDS) secondary to sepsis or transfusion related lung injury. There are certain special situations like head injury where the primary culprit is not the lung, but the brain and the ventilator strategy is aimed at preserving the brain tissue and the respiratory system takes a second place. The present article aims to delineate the strategies addressing practical problems and challenges faced by intensivists dealing with trauma patients with or without healthy lungs. The lung protective strategies along with newer trends in ventilation are discussed. Ventilatory management for specific organ system trauma are highlighted and their physiological base is presented.

    The Qafzeh site (Lower Galilee, Israel) has yielded the largest Levantine hominin collection from Middle Palaeolithic layers which were dated to circa 90–100 kyrs BP or to marine isotope stage 5b–c. Within the hominin sample, Qafzeh 11, circa 12–13 yrs old at death, presents a skull lesion previously attributed to a healed trauma. Three dimensional imaging methods allowed us to better explore this lesion which appeared as being a frontal bone depressed fracture, associated with brain damage. Furthermore the endocranial volume, smaller than expected for dental age, supports the hypothesis of a growth delay due to traumatic brain injury. This trauma did not affect the typical human brain morphology pattern of the right frontal and left occipital petalia. It is highly probable that this young individual suffered from personality and neurological troubles directly related to focal cerebral damage. Interestingly this young individual benefited of a unique funerary practice among the south-western Asian burials dated to Middle Palaeolithic. PMID:25054798

    Suspension trauma (also known as “harness‐induced pathology” or “orthostatic shock while suspended”) is the development of presyncopal symptoms and loss of consciousness if the human body is held motionless in a vertical position for a period of time. It has been described in experiments of personal fall protection, and has been implicated in causes of death in mountaineering accidents, but it seems neither to be widely known about nor to have been presented to the medical profession. This article highlights the potential existence of suspension trauma and suggests that more robust medical research using modern harnesses and healthy volunteers would be beneficial to assess whether this is purely a theoretical risk.

    Statistics and probability theory have advanced our understanding of random processes widely observed in the physical world. There is a remarkable trend in studying the brain by looking into the stochastic information processing in large-scale brain networks [1,2]. As the review by Mannino and Bressler [3] points out, the probabilistic notion of causality, with its rooted philosophical foundations, represents a revolutionary view on how different parts of the brain interact and integrate to generate function. Specifically, Probabilistic Causality (PC) asserts that a cause should increase the probability of occurrence of its effect, and PC between two brain regions entails that the probability for the activity in one region to occur increases when conditioned on the activity of the other. This definition claims inherent randomness in the causal relationship.

    2016-01-01

    Objective To investigate the association of lack of insurance and African-American race with the probability of transfer to level I/II trauma centers, after evaluation in the ED of level III/IV trauma centers for TBI. Summary Background Data The influence of non-medical factors on the disposition of TBI patients initially seen in less specialized institutions is debated. Methods We performed a retrospective cohort study involving TBI patients, who were registered in the National Trauma Data Bank between 2009 and 2011. Regression methods were used to investigate the association of insurance status and race with the disposition of TBI patients evaluated in less specialized trauma centers. Results During the study period, there were 26,031 TBI patients, who were registered in NTDB and met inclusion criteria. Of these, 10,572 (35.9%) were transferred to a higher level of care institution. Multivariable logistic regression after coarsened exact matching demonstrated an association of uninsured patients with increased possibility of transfer (OR, 1.22; 95% CI, 1.05-1.42). On the contrary, there was no association of African-Americans with transfers (OR, 1.27; 95% CI, 0.99-1.62). Those with GCS above 8 (OR, 1.22; 95% CI, 1.08-1.39), or ISS below 16 (OR, 1.33; 95% CI, 1.13-1.56) had a higher possibility of transfer. Conclusions In TBI patients, lack of insurance was associated with increased possibility of transfer to higher level of care institutions, after evaluation in a level III or IV trauma center ED. Regardless of insurance status, this transfer pattern was also observed for African-Americans, but only for those with milder injuries. PMID:26020113

  19. Toxic trauma.

    Hazardous materials (HAZMAT) carry many inherent dangers. Such materials are distributed widely in industrial and military sites. Toxic trauma (TT) denotes the complex of systemic and organ injury caused by toxic agents. Often, TT is associated with other injuries that also require the application of life-support techniques. Rapid onset of acute respiratory failure and consequent cardiovascular failure are of primary concern. Management of TT casualties is dependent upon the characteristics of the toxic agents involved and on the demographics surrounding the HAZMAT incident. Agents that can produce TT possess two pairs of salient characteristics: (1) causality (toxicity and latency), and (2) EMS system (persistency and transmissibility). Two characteristics of presentations are important: (1) incident presentation, and (2) casualty presentation. In addition, many of these agents complicate the processes associated with anaesthesia and must be dealt with. Failure of recognition of these factors may result in the development of respiratory distress syndromes and multiorgan system failure, or even death. PMID:11513285

    Objective We sought to identify a scale or components of a scale that optimize detection of older adult TBI patients who require transport to a trauma center, regardless of mechanism. Methods We assembled a consensus panel consisting of nine experts in geriatric emergency medicine, prehospital medicine, trauma surgery, geriatric medicine, and TBI, as well as prehospital providers, to evaluate the existing scales used to identify TBI. We reviewed the relevant literature and solicited group feedback to create a list of candidate scales and criteria for evaluation. Using the nominal group technique, scales were evaluated by the expert panel through an iterative process until consensus was achieved. Results We identified 15 scales for evaluation. The panel’s criteria for rating the scales included: ease of administration, prehospital familiarity with scale components, feasibility of use with older adults, time to administer, and strength of evidence for their performance in the prehospital setting. After review and discussion of aggregated ratings, the panel identified the Simplified Motor Scale, GCS–Motor Component, and AVPU (alert, voice, pain, unresponsive) as the strongest scales but determined that none meet all EMS provider and patient needs due to poor usability and lack of supportive evidence. The panel proposed that a dichotomized decision scheme that includes domains of the top-rated scales — level of alertness (alert vs. not alert) and motor function (obeys commands vs. does not obey) — may be more effective in identifying older adult TBI patients who require transport to a trauma center in the prehospital setting. Conclusions Existing scales to identify TBI are inadequate to detect older adult TBI patients who require transport to a trauma center. A new algorithm, derived from elements of previously established scales, has potential to guide prehospital providers in improving the triage of older adult TBI patients, but needs further evaluation prior

  1. Hypothermia and the trauma patient

    PubMed Central

    Kirkpatrick, Andrew W.; Chun, Rosaleen; Brown, Ross; Simons, Richard K.

    Hypothermia has profound effects on every system in the body, causing an overall slowing of enzymatic reactions and reduced metabolic requirements. Hypothermic, acutely injured patients with multisystem trauma have adverse outcomes when compared with normothermic control patients. Trauma patients are inherently predisposed to hypothermia from a variety of intrinsic and iatrogenic causes. Coagulation and cardiac sequelae are the most pertinent physiological concerns. Hypothermia and coagulopathy often mandate a simplified approach to complex surgical problems. A modification of traditional classification systems of hypothermia, applicable to trauma patients is suggested. There are few controlled investigations, but clinical opinion strongly supports the active prevention of hypothermia in the acutely traumatized patient. Preventive measures are simple and inexpensive, but the active reversal of hypothermia is much more complicated, often invasive and controversial. The ideal method of rewarming is unclear but must be individualized to the patient and is institution specific. An algorithm reflecting newer approaches to traumatic injury and technical advances in equipment and techniques is suggested. Conversely, hypothermia has selected clinical benefits when appropriately used in cases of trauma. Severe hypothermia has allowed remarkable survivals in the course of accidental circulatory arrest. The selective application of mild hypothermia in severe traumatic brain injury is an area with promise. Deliberate circulatory arrest with hypothermic cerebral protection has also been used for seemingly unrepairable injuries and is the focus of ongoing research. PMID:10526517

    Blunt thoracic aortic injury (BTAI) remains a common cause of death following blunt mechanisms of trauma. Among patients who survive to reach hospital care, significant advances in diagnosis and treatment afford previously unattainable survival. The Society for Vascular Surgery (SVS) guidelines provide current best-evidence suggestions for treatment of BTAI. However, several key areas of controversy regarding optimal BTAI care remain. These include the refinement of selection criteria, timing for treatment and the need for long-term follow-up data. In addition, the advent of the Aortic Trauma Foundation (ATF) represents an important development in collaborative research in this field.

    For millennia, causality served as a powerful guiding principle to our understanding of natural processes, including the functioning of our body, mind, and brain. The target paper presents an impressive vista of the field of causality in brain networks, starting from philosophical issues, expanding on neuroscience effects, and addressing broad engineering and societal aspects as well. The authors conclude that the concept of stochastic causality is more suited to characterize the experimentally observed complex dynamical processes in large-scale brain networks, rather than the more traditional view of deterministic causality. We strongly support this conclusion and provide two additional examples that may enhance and complement this review: (i) a generalization of the Wiener-Granger Causality (WGC) to fit better the complexity of brain networks; (ii) employment of criticality as a key concept highly relevant to interpreting causality and non-locality in large-scale brain networks.

    Understanding cause-and-effect (causal) relations from observations concerns all sciences including neuroscience. Appropriately defining causality and its nature, though, has been a topic of active discussion for philosophers and scientists for centuries. Although brain research, particularly functional neuroimaging research, is now moving rapidly beyond identification of brain regional activations towards uncovering causal relations between regions, the nature of causality has not be been thoroughly described and resolved. In the current review article [1], Mannino and Bressler take us on a beautiful journey into the history of the work on causality and make a well-reasoned argument that the causality in the brain is inherently probabilistic. This notion is consistent with brain anatomy and functions, and is also inclusive of deterministic cases of inputs leading to outputs in the brain.

    The human brain is an impossibly difficult cartographic landscape to map out. Within it's convoluted and labyrinthine structure is folded a million years of phylogeny, somehow expressed in the ontogeny of the specific organism; an ontogeny that conceals idiosyncratic effects of countless genes, and then the (perhaps) countably infinite effects of processes of the organism's lifespan subsequently resulting in remarkable heterogeneity [1,2]. The physical brain itself is therefore a nearly un-decodable "time machine" motivating more questions than frameworks for answering those questions: Why has evolution endowed it with the general structure that is possesses [3]; Is there regularity in macroscopic metrics of structure across species [4]; What are the most meaningful structural units in the brain: molecules, neurons, cortical columns or cortical maps [5]? Remarkably, understanding the intricacies of structure is perhaps not even the most difficult aspect of understanding the human brain. In fact, and as recently argued, a central issue lies in resolving the dialectic between structure and function: how does dynamic function arises from static (at least at the time scales at which human brain function is experimentally studied) brain structures [6]? In other words, if the mind is the brain "in action", how does it arise?

    Although trauma exposure is common, few people develop acute and chronic psychiatric disorders. Those who develop posttraumatic stress disorder likely have coexisting psychiatric and physical disorders. Psychiatric nurses must be knowledgeable about trauma responses, implement evidence-based approaches to conduct assessments, and create safe environments for patients. Most researchers assert that trauma-focused cognitive-behavioral approaches demonstrate the most efficacious treatment outcomes. Integrated approaches, offer promising treatment options. This article provides an overview of clinical factors necessary to help the trauma survivor begin the process of healing and recovery and attain an optimal level of functioning. PMID:27229285

    Chest trauma is one important factor for total morbidity and mortality in traumatized emergency patients. The complexity of injury in trauma patients makes it challenging to provide an optimal oxygenation while protecting the lung from further ventilator-induced injury to it. On the other hand, lung trauma needs to be treated on an individual basis, depending on the magnitude, location and type of lung or chest injury. Several aspects of ventilatory management in emergency patients are summarized herein and may give the clinician an overview of the treatment possibilities for chest trauma victims. PMID:21769213

    Patients who have recovered from traumatic brain injury (TBI) show an increased risk of premature death. To investigate long-term mortality rates in a population admitted to the hospital for head injury (HI), we conducted a population-based prospective case-control, record-linkage study, All subjects who were living in Northern Ostrobothnia, and who were admitted to Oulu University Hospital in 1999 because of HI (n=737), and 2196 controls matched by age, gender, and residence randomly drawn from the population of Northern Ostrobothnia were included. Death rate and causes of death in HI subjects during 15 years of follow-up was compared with the general population controls. The crude mortality rates were 56.9, 18.6, and 23.8% for subjects having moderate-to-severe traumatic brain injury (TBI), mild TBI, and head injury without TBI, respectively. The corresponding approximate annual mortality rates were 6.7%, 1.4%, and 1.9%. All types of index HI predicted a significant risk of traumatic death in the future. Subjects who had HI without TBI had an increased risk of both death from all causes (hazard ratio 2.00; 95% confidence interval 1.57-2.55) and intentional or unintentional traumatic death (4.01, 2.20-7.30), compared with controls. The main founding was that even HI without TBI carries an increased risk of future traumatic death. The reason for this remains unknown and further studies are needed. To prevent such premature deaths, post-traumatic therapy should include an interview focusing on lifestyle factors.

    Previous studies have demonstrated that patients with posttraumatic stress disorder (PTSD) caused by different types of trauma may show divergence in epidemiology, clinical manifestation and treatment outcome. However, it is still unclear whether this divergence has neuroanatomic correlates in PTSD brains. To elucidate the general and trauma-specific cortical morphometric alterations, we performed a meta-analysis of grey matter (GM) changes in PTSD (N = 246) with different traumas and trauma-exposed controls (TECs, N = 347) using anisotropic effect-size signed differential mapping and its subgroup analysis. Our results revealed general GM reduction (GMR) foci in the prefrontal-limbic-striatal system of PTSD brains when compared with those of TECs. Notably, the GMR patterns were trauma-specific. For PTSD by single-incident traumas, GMR foci were found in bilateral medial prefrontal cortex (mPFC), anterior cingulate cortex (ACC), insula, striatum, left hippocampus and amygdala; and for PTSD by prolonged traumas in the left insula, striatum, amygdala and middle temporal gyrus. Moreover, Clinician-Administered PTSD Scale scores were found to be negatively associated with the GM changes in bilateral ACC and mPFC. Our study indicates that the GMR patterns of PTSD are associated with specific traumas, suggesting a stratified diagnosis and treatment for PTSD patients. PMID:27651030

    Studies have shown that early life trauma may influence neural development and increase the risk of developing psychological disorders in adulthood. We used magnetic resonance imaging to examine the impact of early life trauma on the relationship between current posttraumatic stress disorder (PTSD) symptoms and cortical thickness/subcortical volumes in a sample of deployed personnel from Operation Enduring Freedom/Operation Iraqi Freedom. A group of 108 service members enrolled in the Translational Research Center for Traumatic Brain Injury and Stress Disorders (TRACTS) were divided into those with interpersonal early life trauma (EL-Trauma+) and Control (without interpersonal early life trauma) groups based on the Traumatic Life Events Questionnaire. PTSD symptoms were assessed using the Clinician-Administered PTSD Scale. Cortical thickness and subcortical volumes were analyzed using the FreeSurfer image analysis package. Thickness of the paracentral and posterior cingulate regions was positively associated with PTSD severity in the EL-Trauma+ group and negatively in the Control group. In the EL-Trauma+ group, both the right amygdala and the left hippocampus were positively associated with PTSD severity. This study illustrates a possible influence of early life trauma on the vulnerability of specific brain regions to stress. Changes in neural morphometry may provide information about the emergence and maintenance of symptoms in individuals with PTSD.

    Long-term survival after severe trauma is rarely addressed in German trauma journals although knowledge of life expectancy and identification of factors contributing to increased mortality are important for lifetime care management, development of service models, and targeting health promotion and prevention interventions. As reliable data in Germany are lacking, we compiled data mainly from the USA and Australia to describe life expectancy, risk factors, and predictors of outcome in patients experiencing traumatic spinal cord injury, traumatic brain injury, and polytrauma. Two years after trauma, life expectancy in all three categories was significantly lower than that of the general population. It depends strongly on severity of disability, age, and gender and is quantifiable. Whereas improvements in medical care have led to a marked decline in short-term mortality, surprisingly long-term survival in severe trauma has not changed over the past 30 years. Therefore, there is need to intensify long-term trauma patient care and to find new strategies to limit primary damage. PMID:27342106

    Acute treatment with the 5-HT(1A) receptor agonist 8-hydroxy-2-(di-n-propylamino)tetralin (8-OH-DPAT) or chronic environmental enrichment (EE) hasten behavioral recovery after experimental traumatic brain injury (TBI). The aim of this study was to determine if combining these interventions would confer additional benefit. Anesthetized adult male rats received either a cortical impact or sham injury followed 15min later by a single intraperitoneal injection of 8-OH-DPAT (0.5mg/kg) or saline vehicle (1.0mL/kg) and then randomly assigned to either enriched or standard (STD) housing. Behavioral assessments were conducted utilizing established motor and cognitive tests on post-injury days 1-5 and 14-18, respectively. Hippocampal CA(1)/CA(3) neurons were quantified at 3 weeks. Both 8-OH-DPAT and EE attenuated CA(3) cell loss. 8-OH-DPAT enhanced spatial learning in a Morris water maze (MWM) as revealed by differences between the TBI+8-OH-DPAT+STD and TBI+VEHICLE+STD groups (P=0.0014). EE improved motor function as demonstrated by reduced time to traverse an elevated narrow beam in both the TBI+8-OH-DPAT+EE and TBI+VEHICLE+EE groups versus the TBI+VEHICLE+STD group (P=0.0007 and 0.0016, respectively). EE also facilitated MWM learning as evidenced by both the TBI+8-OH-DPAT+EE and TBI+VEHICLE+EE groups locating the escape platform quicker than the TBI+VEHICLE+STD group (P's<0.0001). MWM differences were also observed between the TBI+8-OH-DPAT+EE and TBI+8-OH-DPAT+STD groups (P=0.0004) suggesting that EE enhanced the effect of 8-OH-DPAT. However, there was no difference between the TBI+8-OH-DPAT+EE and TBI+VEHICLE+EE groups. These data replicate previous results from our laboratory showing that both a single systemic administration of 8-OH-DPAT and EE improve recovery after TBI and extend those findings by elucidating that the combination of treatments in this particular paradigm did not confer additional benefit.

    Neurologic trauma, which consists of acute spinal cord injury and traumatic brain injury, is a leading cause of death and disability. In recent years, there have been improvements in the early recognition and prompt resuscitation of patients with neurologic trauma. However, there remain few pharmacologic treatments to reduce its secondary complications. Corticosteroids have been used in patients with neurologic trauma for more than 5 decades. Traditionally, their use has been to improve motor and sensory recovery. However, recently their utility to prevent and manage trauma-related pneumonia has been investigated. Given these new investigations, the purpose of this review article is to provide a comprehensive overview of the history and available scientific evidence surrounding the use of corticosteroids in neurologic trauma and caution against the use of these agents to prevent hospital-acquired pneumonia in this patient population.

    Children enter foster care with many forms of adversity and trauma beyond maltreatment that impact their short- and long-term physical, mental, and developmental health and their adaptation to their new care environment. Applying an understanding of the impact of toxic stress on the developing brain and body allows the health care provider to understand findings in this vulnerable population. Complex trauma alters immune response, neurodevelopment, and the genome, resulting in predictable and significant cognitive, behavioral, and physical consequences. Pediatric care of children in foster care must be trauma informed to meet their medical, mental health, and developmental needs.

    Violence has impacted every aspect of daily life. These tragedies have shocked the world. This has resulted in school communities being fractured. Additionally, The National Survey of Children Exposed to Violence found that 60% of the children surveyed have been exposed to some form of trauma, either in or out of school. Traumatology research has shown most people respond to a wide range of traumatic events in similar ways. The common responses include traumatic responses, posttraumatic stress responses, and posttraumatic stress disorder (PTSD). In this article the authors outline the impact of trauma on children within school systems; discuss the mental health services schools are providing; present a trauma-informed school model; identifies tools which can be utilized in schools; and provide resources needed for a trauma-informed school, along with additional tools and resources. The authors discuss future recommendations for the community and schools as traumatic events continue to grow and impact a large number of children.

  7. Review of pancreatic trauma.

    1989-01-01

    In reviewing the literature on pancreatic trauma (1,984 cases), I found that it resulted from penetrating trauma in 73% and blunt trauma in 27% of cases. Associated injuries were common (average 3.0 per patient). Increased mortality was associated with shotgun wounds, an increasing number of associated injuries, the proximity of the injury to the head of the pancreas, preoperative shock, and massive hemorrhage. High mortality was found for total pancreatectomy, duct reanastomosis, and lack of surgical treatment, with lower mortality for Roux-en-Y anastomoses, suture and drainage, distal pancreatectomy, and duodenal exclusion and diverticulization techniques. Most patients required drainage only. The preoperative diagnosis of pancreatic trauma is difficult, with the diagnosis usually made during surgical repair for associated injuries. Blood studies such as amylase levels, diagnostic peritoneal lavage, and plain radiographs are not reliable. Computed tomographic scanning may be superior, but data are limited. PMID:2669347

  8. Animal Models of Head Trauma

    2005-01-01

    Summary: Animal models of traumatic brain injury (TBI) are used to elucidate primary and secondary sequelae underlying human head injury in an effort to identify potential neuroprotective therapies for developing and adult brains. The choice of experimental model depends upon both the research goal and underlying objectives. The intrinsic ability to study injury-induced changes in behavior, physiology, metabolism, the blood/tissue interface, the blood brain barrier, and/or inflammatory- and immune-mediated responses, makes in vivo TBI models essential for neurotrauma research. Whereas human TBI is a highly complex multifactorial disorder, animal trauma models tend to replicate only single factors involved in the pathobiology of head injury using genetically well-defined inbred animals of a single sex. Although such an experimental approach is helpful to delineate key injury mechanisms, the simplicity and hence inability of animal models to reflect the complexity of clinical head injury may underlie the discrepancy between preclinical and clinical trials of neuroprotective therapeutics. Thus, a search continues for new animal models, which would more closely mimic the highly heterogeneous nature of human TBI, and address key factors in treatment optimization. PMID:16389305

    Penetrating extremity trauma (PET) usually becomes less important when present along with multiple truncal injuries. The middle eastern wars documented the terrible mortality and morbidity resulting from PET. Even in civilian trauma, PET can lead to significant morbidity and mortality. There are now well-established principles in the evaluation and management of vascular, bony, soft tissue, and neurologic lesions that will lead to a reduction of the poor outcomes. This review will summarize some of these recent concepts.

    Traumatic disease is a major public health concern. Monitoring the quality of services provided is essential for the maintenance and improvement thereof. Assessing and monitoring the quality of care in trauma patient through quality indicators would allow identifying opportunities for improvement whose implementation would improve outcomes in hospital mortality, functional outcomes and quality of life of survivors. Many quality indicators have been used in this condition, although very few ones have a solid level of scientific evidence to recommend their routine use. The information contained in the trauma registries, spread around the world in recent decades, is essential to know the current health care reality, identify opportunities for improvement and contribute to the clinical and epidemiological research.

  11. Noninvasive ventilation in trauma

    PubMed Central

    Karcz, Marcin K; Papadakos, Peter J

    2015-01-01

    Trauma patients are a diverse population with heterogeneous needs for ventilatory support. This requirement depends mainly on the severity of their ventilatory dysfunction, degree of deterioration in gaseous exchange, any associated injuries, and the individual feasibility of potentially using a noninvasive ventilation approach. Noninvasive ventilation may reduce the need to intubate patients with trauma-related hypoxemia. It is well-known that these patients are at increased risk to develop hypoxemic respiratory failure which may or may not be associated with hypercapnia. Hypoxemia in these patients is due to ventilation perfusion mismatching and right to left shunt because of lung contusion, atelectasis, an inability to clear secretions as well as pneumothorax and/or hemothorax, all of which are common in trauma patients. Noninvasive ventilation has been tried in these patients in order to avoid the complications related to endotracheal intubation, mainly ventilator-associated pneumonia. The potential usefulness of noninvasive ventilation in the ventilatory management of trauma patients, though reported in various studies, has not been sufficiently investigated on a large scale. According to the British Thoracic Society guidelines, the indications and efficacy of noninvasive ventilation treatment in respiratory distress induced by trauma have thus far been inconsistent and merely received a low grade recommendation. In this review paper, we analyse and compare the results of various studies in which noninvasive ventilation was applied and discuss the role and efficacy of this ventilator modality in trauma.

    Langeron, O; Birenbaum, A; Amour, J

    2009-05-01

    Maintenance of a patent and prevention of aspiration are essential for the management of the trauma patient, that requires experienced physicians in airway control techniques. Difficulties of the airway control in the trauma setting are increased by the vital failures, the risk of aspiration, the potential cervical spine injury, the combative patient, and the obvious risk of difficult tracheal intubation related to specific injury related to the trauma. Endotracheal intubation remains the gold standard in trauma patient airway management and should be performed via the oral route with a rapid sequence induction and a manual in-line stabilization maneuver, to decrease the risks previously mentioned. Different techniques to control the airway in trauma patients are presented: improvement of the laryngoscopic vision, lighted stylet tracheal intubation, retrograde technique for orotracheal intubation, the laryngeal mask and the intubating laryngeal mask airways, the combitube and cricothyroidotomy. Management of the airway in trauma patients requires regular training in these techniques and the knowledge of complementary techniques allowing tracheal intubation or oxygenation to overcome difficult intubation and to prevent major complications as hypoxemia and aspiration.

    Ten percent of deaths worldwide are due to trauma, and it is the third most common cause of death in the United States. Despite a profound upregulation in procoagulant mechanisms, one-quarter of trauma patients present with laboratory-based evidence of trauma-induced coagulopathy (TIC), which is associated with poorer outcomes including increased mortality. The most common causes of death after trauma are hemorrhage and traumatic brain injury (TBI). The management of TIC has significant implications in both because many hemorrhagic deaths could be preventable, and TIC is associated with progression of intracranial injury after TBI. This review covers the most recent evidence and advances in our understanding of TIC, including the role of platelet dysfunction, endothelial activation, and fibrinolysis. Trauma induces a plethora of biochemical and physiologic changes, and despite numerous studies reporting differences in coagulation parameters between trauma patients and uninjured controls, it is unclear whether some of these differences may be "normal" after trauma. Comparisons between trauma patients with differing outcomes and use of animal studies have shed some light on this issue, but much of the data continue to be correlative with causative links lacking. In particular, there are little data linking the laboratory-based abnormalities with true clinically evident coagulopathic bleeding. For these reasons, TIC continues to be a significant diagnostic and therapeutic challenge. PMID:27381903

    PubMed Central

    1996-01-01

    OBJECTIVE. This study examines the cost of providing trauma services in trauma centers organized by publicly administered trauma systems, compared to hospitals not part of a formal trauma system. DATA SOURCES AND STUDY SETTING. Secondary administrative discharge abstracts for a national sample of severely injured trauma patients in 44 trauma centers and 60 matched control hospitals for the year 1987 were used. STUDY DESIGN. Retrospective univariate and multivariate analyses were conducted to examine the impact of formal trauma systems and trauma center designation on the costs of treating trauma patients. Key dependent variables included length of stay, charge per day per patient, and charge per hospital stay. Key impact variables were type of trauma system and level of trauma designation. Control variables included patient, hospital, and community characteristics. DATA COLLECTION/EXTRACTION METHODS. Data were selected for hospitals based on (1) a large national hospital discharge database, the Hospital Cost and Utilization Project, 1980-1987 (HCUP-2) and (2) a special survey of trauma systems and trauma designation undertaken by the Hospital Research and Educational Trust of the American Hospital Association. PRINCIPAL FINDINGS. The results show that publicly designated Level I trauma centers, which are the focal point of most trauma systems, have the highest charge per case, the highest average charge per day, and similar or longer average lengths of stay than other hospitals. These findings persist after controlling for patient injury and health status, and for demographic characteristics and hospital and community characteristics. CONCLUSIONS. Prior research shows that severely injured trauma patients have greater chances of survival when treated in specialized trauma centers. However, findings here should be of concern to the many states developing trauma systems since the high costs of Level I centers support limiting the number of centers designated at this

  19. Systemic inflammation after trauma.

    PubMed

    Lenz, Andreas; Franklin, Glen A; Cheadle, William G

    2007-12-01

    Trauma is still one of the main reasons for death among the population worldwide. Mortality occurring early after injury is due to "first hits", including severe organ injury, hypoxia, hypovolaemia or head trauma. Massive injury leads to activation of the immune system and the early inflammatory immune response after trauma has been defined as systemic inflammatory response syndrome (SIRS). "Second hits" such as infections, ischaemia/reperfusion or operations can further augment the pro-inflammatory immune response and have been correlated with the high morbidity and mortality in the latter times after trauma. SIRS can lead to tissue destruction in organs not originally affected by the initial trauma with subsequent development of multi-organ dysfunction (MOD). The initial pro-inflammatory response is followed by an anti-inflammatory response and can result in immune suppression with high risk of infection and sepsis. Trauma causes activation of nearly all components of the immune system. It activates the neuroendocrine system and local tissue destruction and accumulation of toxic byproducts of metabolic respiration leads to release of mediators. Extensive tissue injury may result in spillover of these mediators into the peripheral bloodstream to further maintain and augment the pro-inflammatory response. Hormones like ACTH, corticosteroids and catecholamines as well as cytokines, chemokines and alarmins play important roles in the initiation and persistence of the pro-inflammatory response after severe injury. The purpose of this review is therefore to describe the immunological events after trauma and to introduce important mediators and pathways of the inflammatory immune response.

    Trauma management shows significant progress in last decades. Determining the time and place of deaths indicate where to focus to improve our knowledge about trauma. We conducted this retrospective study from data of trauma victims who were brought to a major tertiary hospital which is a level one trauma center in Ankara, Turkey, and died even if during transport or in the hospital between 1 March 2010 and 1 March 2013. The patients' demographic characteristics, trauma mechanisms, time frames and causes of deaths determined by physicians were recorded. Traumas were grouped as "high energy trauma" (HET) and "low energy trauma" (LET). Falls from ground level were defined as LET. 209 traumatic deaths due to trauma or trauma-related conditions were found in the study period. 161 of 209 (78 %) patients suffered from HET. Motor vehicle collisions (MVC) (56 %) were the most common mechanism of trauma followed by burns (16 %), falls (11 %), gunshots (9 %) and stabs (6 %) in this group and traumatic brain injuries (TBI) (41 %) were the most common cause of death followed by circulatory collapse (22 %) and multi-organ failure (20 %). 36 % of deaths occurred before arrival at hospital, 25 % in the first 24 h of admission, 18 % between 2nd and 7th day and 21 % after first week. Trimodal distribution of traumatic deaths was not valid for all types of injuries and the most important factor to decrease traumatic deaths is still prevention. Also we have to keep on searching to improve our knowledge about trauma management. PMID:26037980

    Major injury is the sixth leading cause of death worldwide. Among those under 35 years of age, it is the leading cause of death and disability. Traffic accidents alone are the main cause, fundamentally in low- and middle-income countries. Patients over 65 years of age are an increasingly affected group. For similar levels of injury, these patients have twice the mortality rate of young individuals, due to the existence of important comorbidities and associated treatments, and are more likely to die of medical complications late during hospital admission. No worldwide, standardized definitions exist for documenting, reporting and comparing data on severely injured trauma patients.

    Major injury is the sixth leading cause of death worldwide. Among those under 35 years of age, it is the leading cause of death and disability. Traffic accidents alone are the main cause, fundamentally in low- and middle-income countries. Patients over 65 years of age are an increasingly affected group. For similar levels of injury, these patients have twice the mortality rate of young individuals, due to the existence of important comorbidities and associated treatments, and are more likely to die of medical complications late during hospital admission. No worldwide, standardized definitions exist for documenting, reporting and comparing data on severely injured trauma patients. The most common trauma scores are the Abbreviated Injury Scale (AIS), the Injury Severity Score (ISS) and the Trauma and Injury severity Score (TRISS).

    We have attempted to discuss genital trauma in relatively broad terms. In most cases, patients present with relatively minimal trauma. However, because of the complexity of the structures involved, minimal trauma can lead to significant disability later on. The process of erection requires correct functioning of the arterial, neurologic, and venous systems coupled with intact erectile bodies. The penis is composed of structures that are compliant and distensible to the limits of their compliance. These structures therefore tumesce in equal proportion to each other, allowing for straight erection. Relatively minimal trauma can upset this balance of elasticity, leading to disabling chordee. Likewise, relatively minimal injuries to the vascular erectile structures can lead to significantly disabling spongiofibrosis. The urethra is a conduit of paramount importance. Whereas the development of stricture is generally related to the nature of the trauma, the extent of stricture and of attendant complications is clearly a function of the immediate management. Overzealous debridement can greatly complicate subsequent reconstruction. A delicate balance between aggressive initial management and maximal preservation of viable structures must be achieved. 38 references.

    2014-09-01

    Resuscitation of a severely traumatised patient with the administration of crystalloids, or colloids along with blood products is a common transfusion practice in trauma patients. The determination of this review article is to update on current transfusion practices in trauma. A search of PubMed, Google Scholar, and bibliographies of published studies were conducted using a combination of key-words. Recent articles addressing the transfusion practises in trauma from 2000 to 2014 were identified and reviewed. Trauma induced consumption and dilution of clotting factors, acidosis and hypothermia in a severely injured patient commonly causes trauma-induced coagulopathy. Early infusion of blood products and early control of bleeding decreases trauma-induced coagulopathy. Hypothermia and dilutional coagulopathy are associated with infusion of large volumes of crystalloids. Hence, the predominant focus is on damage control resuscitation, which is a combination of permissive hypotension, haemorrhage control and haemostatic resuscitation. Massive transfusion protocols improve survival in severely injured patients. Early recognition that the patient will need massive blood transfusion will limit the use of crystalloids. Initially during resuscitation, fresh frozen plasma, packed red blood cells (PRBCs) and platelets should be transfused in the ratio of 1:1:1 in severely injured patients. Fresh whole blood can be an alternative in patients who need a transfusion of 1:1:1 thawed plasma, PRBCs and platelets. Close monitoring of bleeding and point of care coagulation tests are employed, to allow goal-directed plasma, PRBCs and platelets transfusions, in order to decrease the risk of transfusion-related acute lung injury.

    Objectives: Trauma is the greatest cause of morbidity and mortality in paediatric/adolescent populations worldwide. This study aimed to describe trauma mechanisms, patterns and outcomes among children with blunt torso trauma admitted to the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective single-centre study involved all children ≤12 years old with blunt torso trauma admitted for paediatric surgical care at SQUH between January 2009 and December 2013. Medical records were analysed to collect demographic and clinical data. Results: A total of 70 children were admitted with blunt torso trauma during the study period, including 39 (55.7%) male patients. The mean age was 5.19 ± 2.66 years. Of the cohort, 35 children (50.0%) received their injuries after having been hit by cars as pedestrians, while 19 (27.1%) were injured by falls, 12 (17.1%) during car accidents as passengers and four (5.7%) by falling heavy objects. According to computed tomography scans, thoracic injuries were most common (65.7%), followed by abdominal injuries (42.9%). The most commonly involved solid organs were the liver (15.7%) and spleen (11.4%). The majority of the patients were managed conservatively (92.9%) with a good outcome (74.3%). The mortality rate was 7.1%. Most deaths were due to multisystem involvement. Conclusion: Among children with blunt torso trauma admitted to SQUH, the main mechanism of injury was motor vehicle accidents. As a result, parental education and enforcement of infant car seat/child seat belt laws are recommended. Conservative management was the most successful approach. PMID:27226913

  10. Aspects of abuse: abusive head trauma.

    2015-03-01

    Abusive Head Trauma (AHT) is a form of child physical abuse that involves inflicted injury to the brain and its associated structures. Abusive Head Trauma, colloquially called Shaken Baby Syndrome, is the most common cause of serious or fatal brain injuries in children aged 2 years and younger. The American Academy of Pediatrics recommends the term Abusive Head Trauma, as opposed to Shaken Baby Syndrome, as the former term encompasses multiple forms of inflicted head injury (inertial, contact, and hypoxic-ischemic) and a range of clinical presentations and radiologic findings and their sequelae. Children diagnosed with AHT are 5 times more likely to die compared with accidentally head-injured children, yet signs and symptoms are not always obvious, and therefore the diagnosis can be overlooked. Therefore, the American Academy of Pediatrics has tasked pediatricians with knowing how and when to begin an evaluation of children with signs and symptoms that could possibly be due to AHT. Overall, a detailed history of present illness and medical history, recognition of physical and radiological findings, and careful interpretation of retinal pathology are important aspects of formulating the differential diagnoses and increasing or decreasing the index of suspicion for AHT.

    The purpose of this article is to depict the spectrum of scrotal injuries in blunt trauma. Scrotal injuries are not very common and are mostly due to blunt trauma from direct injury, sports injuries or motor vehicle accidents. To minimize complications and ensure testicular salvage, rapid and accurate diagnosis is necessary. High-resolution USG is the investigation of choice, as it is readily available, accurate and has been seen to improve outcomes. An understanding of and familiarity with the sonographic appearance of scrotal injuries on the part of the radiologist/sonographer is therefore of key importance. PMID:23833421

    Many youth experience ongoing trauma exposure, such as domestic or community violence. Clinicians often ask whether evidence-based treatments containing exposure components to reduce learned fear responses to historical trauma are appropriate for these youth. Essentially the question is, if youth are desensitized to their trauma experiences, will this in some way impair their responding to current or ongoing trauma? The paper addresses practical strategies for implementing one evidence-based treatment, Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with ongoing traumas. Collaboration with local therapists and families participating in TF-CBT community and international programs elucidated effective strategies for applying TF-CBT with these youth. These strategies included: 1) enhancing safety early in treatment; 2) effectively engaging parents who experience personal ongoing trauma; and 3) during the trauma narrative and processing component focusing on a) increasing parental awareness and acceptance of the extent of the youths’ ongoing trauma experiences; b) addressing youths’ maladaptive cognitions about ongoing traumas; and c) helping youth differentiate between real danger and generalized trauma reminders. Case examples illustrate how to use these strategies in diverse clinical situations. Through these strategies TF-CBT clinicians can effectively improve outcomes for youth experiencing ongoing traumas. PMID:21855140

    Prehospital trauma care developed over the last decades parallel in many countries. Most of the prehospital emergency medical systems relied on input or experiences from military medicine and were often modeled after the existing military procedures. Some systems were initially developed with the trauma patient in mind, while other systems were tailored for medical, especially cardiovascular, emergencies. The key components to successful prehospital trauma care are the well-known ABCs of trauma care: Airway, Breathing, Circulation. Establishing and securing the airway, ventilation, fluid resuscitation, and in addition, the quick transport to the best-suited trauma center represent the pillars of trauma care in the field. While ABC in trauma care has neither been challenged nor changed, new techniques, tools and procedures have been developed to make it easier for the prehospital provider to achieve these goals in the prehospital setting and thus improve the outcome of trauma patients.

    Computed tomographic (CT) finding in 18 patients with temporal bone trauma were reviewed. Eight patients suffered longitudinal fractures of the petrous bone, which were associated with ossicular dislocation in two patients. Transverse fractures were detected in six patients, with a contralateral mastoid fracture in one patient. In four patients, the fractures were restricted to the mastoid region. Of the 14 patients in whom adequate neurologic evaluation was available, seven had a permanent facial nerve or hearing deficit while five suffered at least a transient neurologic deficit related to the temporal bone trauma. Routine head CT (10 mm sections) demonstrated only eight of 19 petrous bone injuries. Evidence of brain trauma or extra-axial hemotoma was seen in 12 patients. In 13 cases, high-resolution CT was also performed, demonstrating temporal bone injuries in all. This latter technique allows rapid and detailed evaluation of temporal bone trauma.

    Pediatric spinal trauma is unique. The developing pediatric spinal column and spinal cord deal with direct impact and indirect acceleration/deceleration or shear forces very different compared to adult patients. In addition children are exposed to different kind of traumas. Moreover, each age group has its unique patterns of injury. Familiarity with the normal developing spinal anatomy and kind of traumas is essential to correctly diagnose injury. Various imaging modalities can be used. Ultrasound is limited to the neonatal time period; plain radiography and computer tomography are typically used in the acute work-up and give highly detailed information about the osseous lesions. Magnetic resonance imaging is more sensitive for disco-ligamentous and spinal cord injuries. Depending on the clinical presentation and timing of trauma the various imaging modalities will be employed. In the current review article, a summary of the epidemiology and distribution of posttraumatic lesions is discussed in the context of the normal anatomical variations due to progressing development of the child.

    Chest Trauma in athletes is a common health problem. However, myocardial infarction secondary to coronary dissection in the setting of blunt chest trauma is extremely rare. We report a case of acute inferior wall myocardial infarction following blunt chest trauma. A 32-year-old male with no relevant medical problems was transferred to our medical center for retrosternal chest pain after being elbowed in the chest during a soccer game. Few seconds later, he started experiencing sharp retrosternal chest pain that was severe to that point where he called the emergency medical service. Upon arrival to the trauma department patient was still complaining of chest pain. ECG demonstrated ST segment elevation in the inferior leads with reciprocal changes in the lateral leads all consistent with active ischemia. After rolling out aortic dissection, patient was loaded with ASA, ticagerlor, heparin and was emergently taken to the cardiac catheterization lab. Coronary angiography demonstrated 100% thrombotic occlusion in the distal right coronary artery with TIMI 0 flow distally. After thrombus aspiration, a focal dissection was noted on the angiogram that was successfully stented. Two days after admission patient was discharged home. Echocardiography prior to discharge showed inferior wall akinesis, normal right ventricular systolic function and normal overall ejection fraction.

    Introduction: Interns are often unprepared to effectively communicate in the acute trauma setting. Despite the many strengths of the Advanced Trauma Life Support (ATLS) program, the main shortcoming within the course is the deficiency of teamwork and leadership training. In this study, we describe the creation of an interdisciplinary boot camp in which interns' basic trauma knowledge, level of confidence, and teamwork skills are assessed. Methods: We designed a one-day, boot camp curriculum for interns of various specialties with the purpose of improving communication and teamwork skills for effective management of acute trauma patients. Our curriculum consisted of a one-day, twelve-hour experience, which included trauma patient simulations, content expert lectures, group discussion of video demonstrations, and skill development workstations. Baseline and acquired knowledge were assessed through the use of confidence surveys, cognitive questionnaires, and a validated evaluation tool of teamwork and leadership skills for trauma Results: Fifteen interns entered the boot camp with an overall confidence score of 3.2 (1-5 scale) in the management of trauma cases. At the culmination of the study, there was a significant increase in the overall confidence level of interns in role delegation, leadership, Crisis Resource Management (CRM) principles, and in the performance of primary and secondary surveys. No significant changes were seen in determining and effectively using the Glasgow Coma Scale, Orthopedic splinting/reduction skills, and effective use of closed-loop communication. Conclusion: An intensive one-day trauma boot camp demonstrated significant improvement in self-reported confidence of CRM concepts, role delegation, leadership, and performance of primary and secondary surveys. Despite the intensive curriculum, there was no significant improvement in overall teamwork and leadership performance during simulated cases. Our boot camp curriculum offers educators a

    Ischemic strokes in children and young adults are fortunately rare. Contrasted with adult ischemic strokes, pediatric stroke etiologies vary greatly and are often unknown. Childhood lacunar strokes and trauma-induced strokes represent particularly uncommon subsets and have been reported infrequently in the literature. It is unique to find a combination of the 2-a lacunar stroke induced by trauma. Underreporting of these trauma-induced ischemic strokes could be responsible for perpetuating the lack of recognition. Here we present a lacunar stroke in a young woman associated with a water sport accident and explore relevant literature encircling deep brain ischemia coinciding with trauma.

    According to the National Trauma Institute (2015), trauma accounts for more than 180,000 deaths each year in the United States. Nurses play a significant role in the care of trauma patients and therefore need appropriate education and training (L. ). Although several courses exist for trauma education, many nurses have not received adequate education in trauma management (B. ; L. ). Trauma Tactics, a 2-day course that focuses on high-fidelity human patient simulation, was created to meet this educational need. This descriptive study was conducted retrospectively to assess the effectiveness of the Trauma Tactics course. Pre- and postsurveys, tests, and simulation performance were used to evaluate professional nurses who participated in Trauma Tactics over a 10-month period. Fifty-five nurses were included in the study. Pre- and postsurveys revealed an increase in overall confidence, test scores increased by an average of 2.5 points, and simulation performance scores increased by an average of 16 points. Trauma Tactics is a high-quality course that provides a valuable and impactful educational experience for nurses. Further research is needed to evaluate the long-term effects of Trauma Tactics and its impacts on quality of care and patient outcomes. PMID:27414143

    Objective: To describe outcomes from a clinical trauma surgical education program that places the board-eligible/board-certified fellow in the role of the attending surgeon (fellow-in-exception [FIE]) during the latter half of a 2-year trauma/surgical critical care fellowship. Summary Background Data: National discussions have begun to explore the question of optimal methods for postresidency training in surgery. Few objective studies are available to evaluate current training models. Methods: We analyzed provider-specific data from both our trauma registry and performance improvement (PI) databases. In addition, we performed TRISS analysis when all data were available. Registry and PI data were analyzed as 2 groups (faculty trauma surgeons and FIEs) to determine experience, safety, and trends in errors. We also surveyed graduate fellows using a questionnaire that evaluated perceptions of training and experience on a 6-point Likert scale. Results: During a 4-year period 7,769 trauma patients were evaluated, of which 46.3% met criteria to be submitted to the PA Trauma Outcome Study (PTOS, ie, more severe injury). The faculty group saw 5,885 patients (2,720 PTOS); the FIE group saw 1,884 patients (879 PTOS). The groups were similar in respect to mechanism of injury (74% blunt; 26% penetrating both groups) and injury severity (mean ISS faculty 10.0; FIEs 9.5). When indexed to patient contacts, FIEs did more operations than the faculty group (28.4% versus 25.6%; P < 0.05). Death rates were similar between groups (faculty 10.5%; FIEs 10.0%). Analysis of deaths using PI and TRISS data failed to demonstrate differences between the groups. Analysis of provider-specific errors demonstrated a slightly higher rate for FIEs when compared with faculty when indexed to PTOS cases (4.1% versus 2.1%; P < 0.01). For both groups, errors in management were more common than errors in technique. Twenty-one (91%) of twenty-three surveys were returned. Fellows’ feelings of preparedness

    Immunonutrition may be superior to standard clinical nutrition in specific clinical situations. After severe trauma, an enteral immuno-enhancing diet, enriched with arginine, omega-3 fatty acids, and nucleotides, decreases infectious complications. During acute respiratory distress syndrome, a continuous enteral diet with high-dose omega-3 fatty acids, gamma-linolenic acid, and antioxidants improved clinical outcome. Glutamine should be administered enterally or parenterally whenever total parenteral nutrition is indicated.

    This handbook contains a worksheet for selecting insulation levels based on specific building construction, climate, HVAC equipment, insulation cost, and other economic considerations. The worksheet permits optimization of foundation insulation levels for new or retrofit applications. Construction details representing good practices for the design and installation of energy efficient basement, crawl space, and slab-n-grade foundations are the focal point of the handbook. The construction details are keyed to lists of critical design information useful for specifying structural integrity; thermal and vapor control; subsurface drainage; waterproofing; and mold, mildew, odor, decay, termite, and radon control strategies. Another useful feature are checklist chapter summaries covering major design considerations for each foundation type--basement, crawl space, and slab-on-grade. These checklist summaries are useful during design and construction inspection. The information in this handbook is drawn heavily from the first foundation handbook from the DOE/ORNL Building Envelope Systems and Materials Program, the Building Foundation Design Handbook (Labs et al., 1988), which is an extensive technical reference manual. This book presents what to do in foundation design'' in an inviting, concise format. This handbook is intended to serve the needs of active home builders; however, the information is pertinent to anyone involved in foundation design and construction decisions including homeowners, architects, and engineers. 17 refs., 49 figs., 18 tabs.

    Kirmayer, Laurence J; Gone, Joseph P; Moses, Joshua

    2014-06-01

    Recent years have seen the rise of historical trauma as a construct to describe the impact of colonization, cultural suppression, and historical oppression of Indigenous peoples in North America (e.g., Native Americans in the United States, Aboriginal peoples in Canada). The discourses of psychiatry and psychology contribute to the conflation of disparate forms of violence by emphasizing presumptively universal aspects of trauma response. Many proponents of this construct have made explicit analogies to the Holocaust as a way to understand the transgenerational effects of genocide. However, the social, cultural, and psychological contexts of the Holocaust and of post-colonial Indigenous "survivance" differ in many striking ways. Indeed, the comparison suggests that the persistent suffering of Indigenous peoples in the Americas reflects not so much past trauma as ongoing structural violence. The comparative study of genocide and other forms of massive, organized violence can do much to illuminate both common mechanisms and distinctive features, and trace the looping effects from political processes to individual experience and back again. The ethics and pragmatics of individual and collective healing, restitution, resilience, and recovery can be understood in terms of the self-vindicating loops between politics, structural violence, public discourse, and embodied experience.

    Cervical spine trauma is a common problem with a wide range of severity from minor ligamentous injury to frank osteo-ligamentous instability with spinal cord injury. The emergent evaluation of patients at risk relies on standardized clinical and radiographic protocols to identify injuries; elucidate associated pathology; classify injuries; and predict instability, treatment and outcomes. The unique anatomy of each region of the cervical spine demands a review of each segment individually. This article examines both upper cervical spine injuries, as well as subaxial spine trauma. The purpose of this article is to provide a review of the broad topic of cervical spine trauma with reference to the classic literature, as well as to summarize all recently available literature on each topic. Identification of References for Inclusion: A Pubmed and Ovid search was performed for each topic in the review to identify recently published articles relevant to the review. In addition prior reviews and classic references were evaluated individually for inclusion of classic papers, classifications and previously unidentified references. PMID:21139776

    External laryngeal trauma is a rare but potentially life-threatening situation in the acutely injured patient. Trauma mechanism and magnitude, maximum focus of the applied force, and patient related factors, such as age and ossification of the laryngeal cartilages influence the spectrum of observed injuries. Their correct diagnosis and prompt management are paramount in order to avoid patient death or long-term impairment of breathing, swallowing and speaking. The current review provides a comprehensive approach to the radiologic interpretation of imaging studies performed in patients with suspected laryngeal injury. It describes the key anatomic structures that are relevant in laryngeal trauma and discusses the clinical role of multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) in the acute emergency situation. The added value of two-dimensional multiplanar reconstructions (2D MPR), three-dimensional volume rendering (3D VR) and virtual endoscopy (VE) for the non-invasive evaluation of laryngeal injuries and for treatment planning is discussed. The clinical presentation, biomechanics of injury, diagnostic pitfalls and pearls, common and uncommon findings are reviewed with emphasis of fracture patterns, involvement of laryngeal joints, intra- and extralaryngeal soft tissue injuries, and complications seen in the acute emergency situation. The radiologic appearance of common and less common long-term sequelae, as well as treatment options are equally addressed.

  18. The trauma team--a system of initial trauma care.

    Trauma remains the leading cause of death under the age of 35 years. England and Wales lost 252,000 working years from accidental deaths, including poison, in 1992. In this country, preventable deaths from trauma are inappropriately high. In many hospitals there are not enough personnel; in the majority, there are no recognisable trauma care systems, which can reduce preventable deaths to a minimum. The appropriateness of trauma centres for this country is being assessed in Stoke-on-Trent, and a report is due out later this year. Even if the recommendation is made to establish such centres, it is unlikely that many will be set up. Consequently most hospitals will have to rely on their own resources to set up and run a trauma team. This type of trauma care system is the subject of this article. PMID:8977939

    Neuroimaging plays an important role in the management of head trauma. Several guidelines have been published for identifying which patients can avoid neuroimaging. Noncontrast head CT is the most appropriate initial examination in patients with minor or mild acute closed head injury who require neuroimaging as well as patients with moderate to severe acute closed head injury. In short-term follow-up neuroimaging of acute traumatic brain injury, CT and MRI may have complementary roles. In subacute to chronic traumatic brain injury, MRI is the most appropriate initial examination, though CT may have a complementary role in select circumstances. Advanced neuroimaging techniques are areas of active research but are not considered routine clinical practice at this time. In suspected intracranial vascular injury, CT angiography or venography or MR angiography or venography is the most appropriate imaging study. In suspected posttraumatic cerebrospinal fluid leak, high-resolution noncontrast skull base CT is the most appropriate initial imaging study to identify the source, with cisternography reserved for problem solving. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every three years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment. PMID:27262056

    Early life trauma exposure represents a potent risk factor for the development of mental illnesses such as anxiety, depression and post-traumatic stress disorder. Moreover, deleterious consequences of trauma are exacerbated in youth living in impoverished, urban environments. A priori probability maps were used to examine resting-state functional connectivity (FC) of the amygdala in 21 trauma-exposed, and 21 age- and sex-matched urban children and adolescents (youth) without histories of trauma. Intrinsic FC analyses focused on amygdala-medial prefrontal circuitry, a key emotion regulatory pathway in the brain. We discovered reduced negative amygdala-subgenual cingulate connectivity in trauma-exposed youth. Differences between groups were also identified in anterior insula and dorsal anterior cingulate to amygdala connectivity. Overall, results suggest a model in which urban-dwelling trauma-exposed youth lack negative prefrontal to amygdala connectivity that may be critical for regulation of emotional responses. Functional changes in amygdala circuitry might reflect the biological embedding of stress reactivity in early life and mediate enhanced vulnerability to stress-related psychopathology. PMID:25836993

  15. Review article: the surgical approach to the management of increased intracranial pressure after traumatic brain injury.

    PubMed

    Li, Lucia M; Timofeev, Ivan; Czosnyka, Marek; Hutchinson, Peter J A

    2010-09-01

    Increased intracranial pressure occurring after severe traumatic brain injury is a common and potentially devastating phenomenon. It has been clearly demonstrated that increased intracranial pressure that is refractory to initial medical measures is a poor prognostic sign. Current optimal management is based on a sequential, target-driven approach combining both medical and surgical treatment strategies. The surgical measures in current common practice include external ventricular drain insertion and decompressive craniectomy. There is evidence that both of these measures reduce intracranial pressure but the effect on outcome, particularly in the long term, is equivocal. Current Brain Trauma Foundation guidelines recommend timely evacuation of mass lesions and there is clear guidance regarding the indications for intracranial pressure monitoring; however, decompressive craniectomy is only cautiously recommended as a possible option for selected patients. In this review, we highlight the ongoing debate about the use of decompressive craniectomy to control intracranial pressure after traumatic brain injury; included is a summary of review of the most recent literature on the effect of decompressive craniectomy on increased intracranial pressure after traumatic brain injury and associated long-term outcome. The RESCUEicp and DECRA studies are discussed in detail. It is hoped that these 2 randomized controlled trials, which are evaluating the short- and longer-term outcomes of decompressive craniectomy, will provide conclusive evidence regarding the role of decompressive craniectomy in managing increased intracranial pressure after trauma.

    Previous studies have found childhood trauma to be associated with functional and structural abnormalities in corticostriatal-limbic brain regions, which may explain the associations between trauma and negative mental and physical health outcomes. However, functional neuroimaging of maltreatment-related trauma has been limited by largely using generic and predominantly aversive stimuli. Personalized stress, favorite-food, and neutral/relaxing cues during functional magnetic resonance imaging were used to probe the neural correlates of emotional/motivational states in adolescents with varying exposure to maltreatment-related trauma. Sixty-four adolescents were stratified into high- or low-trauma-exposed groups. Cue-related measures of subjective anxiety and craving were collected. Relative to the low-trauma-exposed group, high-trauma-exposed adolescents displayed an increased activation of insula, anterior cingulate, and prefrontal cortex in response to stress cues. Activation in subcortical structures, including the hippocampus, was inversely correlated with subjective anxiety in the high- but not the low-trauma-exposed group. The high-trauma-exposed group displayed hypoactivity of cerebellar regions in response to neutral/relaxing cues. No group differences were observed in response to favorite-food cues. The relationship between trauma exposure and altered cortico-limbic circuitry may in part explain the association between childhood trauma and heightened vulnerability to emotional disturbances and risky behaviour. This may be particularly pertinent during adolescence when such difficulties often emerge. Further work is needed to elucidate the mechanism linking trauma to obesity. PMID:25567424

    Retroclival collections are rare lesions reported almost exclusively in children and strongly associated with trauma. We examine the incidence and imaging characteristics of retroclival collections in young children with abusive head trauma. We conducted a database search to identify children with abusive head trauma ≤ 3 years of age with brain imaging performed between 2007 and 2013. Clinical data and brain images of 65 children were analyzed. Retroclival collections were identified in 21 of 65 (32%) children. Ten (48%) were subdural, 3 (14%) epidural, 2 (10%) both, and 6 (28%) indeterminate. Only 8 of 21 retroclival collections were identifiable on CT and most were low or intermediate in attenuation. Eighteen of 21 retroclival collections were identifiable on MRI: 3 followed cerebral spinal fluid in signal intensity and 15 were bloody/proteinaceous. Additionally, 2 retroclival collections demonstrated a fluid-fluid level and 2 enhanced in the 5 children who received contrast material. Sagittal T1-weighted images, sagittal fluid-sensitive sequences, and axial FLAIR (fluid-attenuated inversion recovery) images showed the retroclival collections best. Retroclival collections were significantly correlated with supratentorial and posterior fossa subdural hematomas and were not statistically correlated with skull fracture or parenchymal brain injury. Retroclival collections, previously considered rare lesions strongly associated with accidental injury, were commonly identified in this cohort of children with abusive head trauma, suggesting that retroclival collections are an important component of the imaging spectrum in abusive head trauma. Retroclival collections were better demonstrated on MRI than CT, were commonly identified in conjunction with intracranial subdural hematomas, and were not significantly correlated with the severity of brain injury or with skull fractures.

    Injury is still the number 1 killer of children ages 1 to 18 years in the United States (http://www.cdc.gov/nchs/fastats/children.htm). Children who sustain injuries with resulting disabilities incur significant costs not only for their health care but also for productivity lost to the economy. The families of children who survive childhood injury with disability face years of emotional and financial hardship, along with a significant societal burden. The entire process of managing childhood injury is enormously complex and varies by region. Only the comprehensive cooperation of a broadly diverse trauma team will have a significant effect on improving the care of injured children.

    Objectives Many youth develop complex trauma, which includes regulation problems in the domains of affect, attachment, behavior, biology, cognition, and perception. Therapists often request strategies for using evidence-based treatments (EBTs) for this population. This article describes practical strategies for applying Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) for youth with complex trauma. Methods TF-CBT treatment phases are described and modifications of timing, proportionality and application are described for youth with complex trauma. Practical applications include a) dedicating proportionally more of the model to the TF-CBT coping skills phase; b) implementing the TF-CBT Safety component early and often as needed throughout treatment; c) titrating gradual exposure more slowly as needed by individual youth; d) incorporating unifying trauma themes throughout treatment; and e) when indicated, extending the TF-CBT treatment consolidation and closure phase to include traumatic grief components and to generalize ongoing safety and trust. Results Recent data from youth with complex trauma support the use of the above TF-CBT strategies to successfully treat these youth. Conclusions The above practical strategies can be incorporated into TF-CBT to effectively treat youth with complex trauma. Practice implications Practical strategies include providing a longer coping skills phase which incorporates safety and appropriate gradual exposure; including relevant unifying themes; and allowing for an adequate treatment closure phase to enhance ongoing trust and safety. Through these strategies therapists can successfully apply TF-CBT for youth with complex trauma. PMID:22749612

  5. Management of Colorectal Trauma

    PubMed Central

    2011-01-01

    Although the treatment strategy for colorectal trauma has advanced during the last part of the twentieth century and the result has improved, compared to other injuries, problems, such as high septic complication rates and mortality rates, still exist, so standard management for colorectal trauma is still a controversial issue. For that reason, we designed this article to address current recommendations for management of colorectal injuries based on a review of literature. According to the reviewed data, although sufficient evidence exists for primary repair being the treatment of choice in most cases of nondestructive colon injuries, many surgeons are still concerned about anastomotic leakage or failure, and prefer to perform a diverting colostomy. Recently, some reports have shown that primary repair or resection and anastomosis, is better than a diverting colostomy even in cases of destructive colon injuries, but it has not fully established as the standard treatment. The same guideline as that for colonic injury is applied in cases of intraperitoneal rectal injuries, and, diversion, primary repair, and presacral drainage are regarded as the standards for the management of extraperitoneal rectal injuries. However, some reports state that primary repair without a diverting colostomy has benefit in the treatment of extraperitoneal rectal injury, and presacral drainage is still controversial. In conclusion, ideally an individual management strategy would be developed for each patient suffering from colorectal injury. To do this, an evidence-based treatment plan should be carefully developed. PMID:21980586

  6. Haemodynamic changes in trauma.

    PubMed

    Kirkman, E; Watts, S

    2014-08-01

    Trauma is the leading cause of death during the first four decades of life in the developed countries. Its haemodynamic response underpins the patient's initial ability to survive, and the response to treatment and subsequent morbidity and resolution. Trauma causes a number of insults including haemorrhage, tissue injury (nociception) and, predominantly, in military casualties, blast from explosions. This article discusses aspects of the haemodynamic responses to these insults and subsequent treatment. 'Simple' haemorrhage (blood loss without significant volume of tissue damage) causes a biphasic response: mean arterial blood pressure (MBP) is initially maintained by the baroreflex (tachycardia and increased vascular resistance, Phase 1), followed by a sudden decrease in MAP initiated by a second reflex (decrease in vascular resistance and bradycardia, Phase 2). Phase 2 may be protective. The response to tissue injury attenuates Phase 2 and may cause a deleterious haemodynamic redistribution that compromises blood flow to some vital organs. In contrast, thoracic blast exposure augments Phase 2 of the response to haemorrhage. However, hypoxaemia from lung injury limits the effectiveness of hypotensive resuscitation by augmenting the attendant shock state. An alternative strategy ('hybrid resuscitation') whereby tissue perfusion is increased after the first hour of hypotensive resuscitation by adopting a revised normotensive target may ameliorate these problems. Finally, morphine also attenuates Phase 2 of the response to haemorrhage in some, but not all, species and this is associated with poor outcome. The impact on human patients is currently unknown and is the subject of a current physiological investigation.

    Prehospital emergency care in Singapore has taken shape over almost a century. What began as a hospital-based ambulance service intended to ferry medical cases was later complemented by an ambulance service under the Singapore Fire Brigade to transport trauma cases. The two ambulance services would later combine and come under the Singapore Civil Defence Force. The development of prehospital care systems in island city-state Singapore faces unique challenges as a result of its land area and population density. This article defines aspects of prehospital trauma care in Singapore. It outlines key historical milestones and current initiatives in service, training, and research. It makes propositions for the future direction of trauma care in Singapore. The progress Singapore has made given her circumstances may serve as lessons for the future development of prehospital trauma systems in similar environments. Key words: Singapore; trauma; prehospital emergency care; emergency medical services.

  13. Maternal mortality due to trauma.

    2012-02-01

    Maternal mortality is an important indicator of adequacy of health care in our society. Improvements in the obstetric care system as well as advances in technology have contributed to reduction in maternal mortality rates. Trauma complicates up to 7% of all pregnancies and has emerged as the leading cause of maternal mortality, becoming a significant concern for the public health system. Maternal mortality secondary to trauma can often be prevented by coordinated medical care, but it is essential that caregivers recognize the unique situation of providing simultaneous care to 2 patients who have a complex physiologic relationship. Optimal management of the pregnant trauma victim requires a multidisciplinary team, where the obstetrician plays a central role. This review focuses on the incidence of maternal mortality due to trauma, the mechanisms involved in traumatic injury, the important anatomic and physiologic changes that may predispose to mortality due to trauma, and finally, preventive strategies that may decrease the incidence of traumatic maternal death.

  14. Chronic Subdural Hematoma in the Aged, Trauma or Degeneration?

    PubMed Central

    2016-01-01

    Chronic subdural hematomas (CSHs) are generally regarded to be a traumatic lesion. It was regarded as a stroke in 17th century, an inflammatory disease in 19th century. From 20th century, it became a traumatic lesion. CSH frequently occur after a trauma, however, it cannot occur when there is no enough subdural space even after a severe head injury. CSH may occur without trauma, when there is sufficient subdural space. The author tried to investigate trends in the causation of CSH. By a review of literature, the author suggested a different view on the causation of CSH. CSH usually originated from either a subdural hygroma or an acute subdural hematoma. Development of CSH starts from the separation of the dural border cell (DBC) layer, which induces proliferation of DBCs with production of neomembrane. Capillaries will follow along the neomembrane. Hemorrhage would occur into the subdural fluid either by tearing of bridge veins or repeated microhemorrhage from the neomembrane. That is the mechanism of hematoma enlargement. Trauma or bleeding tendency may precipitate development of CSH, however, it cannot lead CSH, if there is no sufficient subdural space. The key determinant for development of CSH is a sufficient subdural space, in other words, brain atrophy. The most common and universal cause of brain atrophy is the aging. Modifying Virchow's description, CSH is sometimes traumatic, but most often caused by degeneration of the brain. Now, it is reasonable that degeneration of brain might play pivotal role in development of CSH in the aged persons. PMID:26885279

  17. Penetrating abdominal trauma.

    PubMed

    Henneman, P L

    1989-08-01

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

  5. Skiing and spinal trauma.

    PubMed

    Frymoyer, J W; Pope, M H; Kristiansen, T

    1982-07-01

    Spinal injury in skiers can either be acute or chronic. Acute spinal injury accounts for 3 to 3.6 per cent of all injuries occurring in Alpine skiing. Fewer acute injuries occur in cross-country skiing, and those that do usually are the result of a sudden, compressive force from a seated fall. The prevalence of chronic spinal trauma in skiing is unknown. Both cross-country and Alpine skiers appear to have greater complaints of mild to moderate low back pain as compared with their nonskiing counterparts. These differences may be the result of a complex interaction between recreational and occupational activities. Theoretical analyses suggest a risk for low-grade torsional injury to the Alpine skier's spine, whereas in cross-country skiing significant shear forces are applied to lumbar discs during the kick but not the double-poling phase.

  6. Trauma and religiousness.

    2014-06-01

    Victims of traumatic events who experience re-traumatization often develop a highly ambivalent relationship to God and all religiosity as extremely conflictual. On the one hand, they may choose to blame God for not having protected them, for having left them to feel so alone, for having been indifferent to them or they may even turn their wrath upon God, as the source of cruelty. Often though, the traumas experienced by individuals prompt them to turn to God and religion in search of help. This gives reason for the need of new and up-to-date research that can help elucidate why some people choose to seek help in religion and others turn away from it.

  7. The costs of traumatic brain injury: a literature review

    2013-01-01

    Objective The purpose of this study was to review the literature relating to the psychosocial costs associated with traumatic brain injury (TBI). Methods Nine online journal databases, including MEDLINE, CINAHL, PsychINFO, and PUBMED, were queried for studies between July 2010 and May 2012 pertaining to the economic burden of head injuries. Additional studies were identified through searching bibliographies of related publications and using Google internet search engine. Results One hundred and eight potentially relevant abstracts were identified from the journal databases. Ten papers were chosen for discussion in this review. All but two of the chosen papers were US studies. The studies included a cost-benefit analysis of the implementation of treatment guidelines from the US brain trauma foundation and a cost-effectiveness analysis of post-acute traumatic brain injury rehabilitation. Conclusion Very little research has been published on the economic burden that mild and moderate traumatic brain injury patients pose to their families, careers, and society as a whole. Further research is needed to estimate the economic burden of these patients on healthcare providers and social services and how this can impact current health policies and practices. PMID:23836998

    2007-10-01

    The use of CT in the diagnosis and management of liver trauma is responsible for the shift from routine surgical versus non-surgical treatment in the management of traumatic liver injuries, even when they are of high grade. The main cause of complication and of death in liver trauma is related to vascular injury. The goal of this review focussed on the vascular complications of liver trauma is to describe the elementary lesions shown by CT in liver trauma including laceration, parenchymal hematoma and contusions, partial devascularisation, subcapsular hematomas, hemoperitoneum, active bleeding, pseudoaneurysm of the hepatic artery, bile leak, and periportal oedema, to illustrate the possible pitfalls in CT diagnosis of liver trauma and to underline the key-points which may absolutely be present in a CT report of liver trauma. Then we will remind the grading system based on the CT features and we will analyze the interest and limitations of such grading systems. Last we will discuss the diagnostic strategy at the early phase in patients with suspected liver trauma according to their clinical conditions and underline the conditions of arterial embolization, and then we will discuss the diagnosis strategy at the delayed phase according to the suspected complications.

    2011-01-01

    Background and Objectives Findings on disclosure and adjustment following traumatic events have been mixed. Better understanding of individual differences in disclosure may help us better understand reactions following trauma exposure. In particular, studying disclosure patterns for those with and without psychopathology and for different types of emotional experiences may help clarify the relationship between disclosure, event emotionality, trauma exposure, and PTSD. Methods In this study, 143 men and women with (n = 67) and without (n = 43) chronic PTSD and without trauma exposure (n = 33) provided information on disclosure for a traumatic/severe life event, a negative event, and a positive event. Results Individuals with PTSD reported greater difficulty disclosing their traumatic event compared to those with trauma exposure no PTSD and those with no-trauma exposure. However, individuals with PTSD reported disclosing the traumatic event a similar number of times and with similar levels of detail to those with trauma exposure but no PTSD. Both sexual and childhood trauma were associated with greater disclosure difficulty. Limitations Although control event types (positive, negative) were selected to control for the passage of time and for general disclosure style, they do not control for salience of the event and results may be limited by control events that were not highly salient. Conclusions The present findings point to a dynamic conceptualization of disclosure, suggesting that the differential difficulty of disclosing traumatic events seen in individuals with PTSD is not simply a function of the amount of disclosure or the amount of details provided.

  11. Impact of trauma on children.

    PubMed

    Lubit, Roy; Rovine, Deborah; DeFrancisci, Lea; Eth, Spencer

    2003-03-01

    Millions of children are affected by physical and sexual abuse, natural and technological disasters, transportation accidents, invasive medical procedures, exposure to community violence, violence in the home, assault, and terrorism. Unfortunately, the emotional impact of exposure to trauma on children is often unappreciated and therefore untreated, and yet the impact of exposures to disaster and violence is profound and long-lasting. This article first briefly discusses the epidemiology of trauma in children, and then reviews the psychiatric and neurodevelopmental impact of trauma on children as well as the effects of trauma on children's emotional development. Trauma in children can lead to the development of posttraumatic stress disorder as well as to a variety of other psychiatric disorders, including depression, generalized anxiety disorder, panic attacks, borderline personality disorder, and substance abuse in adult survivors of trauma. Research has found that early exposure to stress and trauma causes physical effects on neurodevelopment which may lead to changes in the individual's long-term response to stress and vulnerability to psychiatric disorders. Exposure to trauma also affects children's ability to regulate, identify, and express emotions, and may have a negative effect on the individual's core identity and ability to relate to others. The authors also discuss what has been learned, based on recent experiences such as the World Trade Center catastrophe, about the role of television viewing in increasing the effects of traumatic events. The last section of the article provides guidance concerning the identification and clinical treatment of children and adolescents who are having emotional problems as a result of exposure to trauma.

  12. Can Innate, modular "foundations" explain morality? Challenges for Haidt's Moral Foundations Theory.

    PubMed

    Suhler, Christopher L; Churchland, Patricia

    2011-09-01

    Jonathan Haidt's Moral Foundations Theory is an influential scientific account of morality incorporating psychological, developmental, and evolutionary perspectives. The theory proposes that morality is built upon five innate "foundations," each of which is believed to have been selected for during human evolution and, subsequently, tuned-up by learning during development. We argue here that although some general elements of Haidt's theory are plausible, many other important aspects of his account are seriously flawed. First, innateness and modularity figure centrally in Haidt's account, but terminological and conceptual problems foster confusion and ambiguities. Second, both the theory's proposed number of moral foundations and its taxonomy of the moral domain appear contrived, ignoring equally good candidate foundations and the possibility of substantial intergroup differences in the foundations' contents. Third, the mechanisms (viz., modules) and categorical distinctions (viz., between foundations) proposed by the theory are not consilient with discoveries in contemporary neuroscience concerning the organization, functioning, and development of the brain. In light of these difficulties, we suggest that Haidt's theory is inadequate as a scientific account of morality. Nevertheless, the theory's weaknesses are instructive, and hence, criticism may be useful to psychologists, neuroscientists, and philosophers attempting to advance theories of morality, as well as to researchers wishing to invoke concepts such as innateness and modularity more generally.

    Background Serum levels of the astrocytic protein S100B have been reported to indicate disruption of the blood–brain barrier. In this study, we investigated the relationship between S100B levels and childhood trauma in a child psychiatric inpatient unit. Method Levels of S100B were measured in a group of youth with mood disorders or psychosis with and without history of childhood trauma as well as in healthy controls. Study participants were 93 inpatient adolescents admitted with a diagnosis of psychosis (N = 67), or mood disorder (N = 26) and 22 healthy adolescents with no history of trauma or psychiatric illness. Childhood trauma was documented using the Life Events Checklist (LEC) and Adverse Child Experiences (ACE). Results In a multivariate regression model, suicidality scores and trauma were the only two variables which were independently related to serum S100B levels. Patients with greater levels of childhood trauma had significantly higher S100B levels even after controlling for intensity of suicidal ideation. Patients with psychotic diagnoses and mood disorders did not significantly differ in their levels of S100B. Patients exposed to childhood trauma were significantly more likely to have elevated levels of S100B (p < .001) than patients without trauma, and patients with trauma had significantly higher S100B levels (p < .001) when compared to the control group. LEC (p 0.046), and BPRS-C suicidality scores (p = 0.001) significantly predicted S100B levels. Conclusions Childhood trauma can potentially affect the integrity of the blood–brain barrier as indicated by associated increased S100B levels. PMID:25669696

    2016-09-01

    Argument This paper reconstructs Wronski's philosophical foundations of mathematics. It uses his critique of Lagrange's algebraic analysis as a vignette to introduce the problems that he raised, and argues that these problems have not been properly appreciated by his contemporaries and subsequent commentators. The paper goes on to reconstruct Wronski's mathematical law of creation and his notions of theory and techne, in order to put his objections to Lagrange in their philosophical context. Finally, Wronski's proof of his universal law (the expansion of a given function by any series of functions) is reviewed in terms of the above reconstruction. I argue that Wronski's philosophical approach poses an alternative to the views of his contemporary mainstream mathematicians, which brings up the contingency of their choices, and bridges the foundational concerns of early modernity with those of the twentieth-century foundations crisis. I also argue that Wronski's views may be useful to contemporary philosophy of mathematical practice, if they are read against their metaphysical grain. PMID:27573997

    Foundation NHS Trusts will be constituted in the same way as Mutual Societies, and local people and patients will be invited to become subscribers. Subscribers will elect a board of governors who will appoint the non-executive directors of the Trusts. Foundation Trusts will be outside the performance management system, but will be subject to a regulator and to inspection. Contracts with commissioners will be legally enforceable. Issues discussed in the article include: financial borrowing; whether competition is being reintroduced; poaching staff; fears of a two-tier health service; fragmentation of the NHS; the impact on research and teaching; and the impact on the current 'target culture'. Local communities and patient groups may welcome involvement with their local hospitals, but special interest groups could be a danger. Foundation Trusts may bring back some of the better features of NHS Trusts as originally conceived, and offer better opportunities for clinicians to influence local policies and priorities. Fears of yet another organisational change are an important issue. Only time will tell whether the outcome will justify the effort the changes will involve. PMID:14703035

  1. Foundations of chaotic mixing.

    PubMed

    Wiggins, Stephen; Ottino, Julio M

    2004-05-15

    The simplest mixing problem corresponds to the mixing of a fluid with itself; this case provides a foundation on which the subject rests. The objective here is to study mixing independently of the mechanisms used to create the motion and review elements of theory focusing mostly on mathematical foundations and minimal models. The flows under consideration will be of two types: two-dimensional (2D) 'blinking flows', or three-dimensional (3D) duct flows. Given that mixing in continuous 3D duct flows depends critically on cross-sectional mixing, and that many microfluidic applications involve continuous flows, we focus on the essential aspects of mixing in 2D flows, as they provide a foundation from which to base our understanding of more complex cases. The baker's transformation is taken as the centrepiece for describing the dynamical systems framework. In particular, a hierarchy of characterizations of mixing exist, Bernoulli --> mixing --> ergodic, ordered according to the quality of mixing (the strongest first). Most importantly for the design process, we show how the so-called linked twist maps function as a minimal picture of mixing, provide a mathematical structure for understanding the type of 2D flows that arise in many micromixers already built, and give conditions guaranteeing the best quality mixing. Extensions of these concepts lead to first-principle-based designs without resorting to lengthy computations.

  2. Disrupted insula-based neural circuit organization and conflict interference in trauma-exposed youth.

    PubMed

    2015-01-01

    Childhood trauma exposure is a potent risk factor for psychopathology. Emerging research suggests that aberrant saliency processing underlies the link between early trauma exposure and later cognitive and socioemotional deficits that are hallmark of several psychiatric disorders. Here, we examine brain and behavioral responses during a face categorization conflict task, and relate these to intrinsic connectivity of the salience network (SN). The results demonstrate a unique pattern of SN dysfunction in youth exposed to trauma (n = 14) relative to comparison youth (n = 19) matched on age, sex, IQ, and sociodemographic risk. We find that trauma-exposed youth are more susceptible to conflict interference and this correlates with higher fronto-insular responses during conflict. Resting-state functional connectivity data collected in the same participants reveal increased connectivity of the insula to SN seed regions that is associated with diminished reward sensitivity, a critical risk/resilience trait following stress. In addition to altered intrinsic connectivity of the SN, we observed altered connectivity between the SN and default mode network (DMN) in trauma-exposed youth. These data uncover network-level disruptions in brain organization following one of the strongest predictors of illness, early life trauma, and demonstrate the relevance of observed neural effects for behavior and specific symptom dimensions. SN dysfunction may serve as a diathesis that contributes to illness and negative outcomes following childhood trauma.

    Late presentation of head trauma is rare. A young boy presented with a traumatic facial paralysis after head trauma. A CT scan of the head showed temporal bone fracture without intracranial insult. Facial nerve decompression was performed and paralysis started improving. However, he presented with vertigo and sensorineural hearing loss after 2 months. Clinical examination also showed cerebellar sign. We suspected iatrogenic injury to the cochlea; however, brain MRI showed haemorrhage in the area of anterior inferior cerebellar artery. The patient was managed conservatively and the vertigo improved. This case stresses on unusual late presentation of head trauma and cerebellar artery injury that complicated the outcome of facial nerve paralysis.

    Lee, Jennifer K; Brady, Ken M; Deutsch, Nina

    2016-06-01

    Abusive head trauma (AHT) is the most common cause of severe traumatic brain injury (TBI) in infants and the leading cause of child abuse-related deaths. For reasons that remain unclear, mortality rates after moderate AHT rival those of severe nonintentional TBI. The vulnerability of the developing brain to injury may be partially responsible for the poor outcomes observed after AHT. AHT is mechanistically more complex than nonintentional TBI. The acute-on-chronic nature of the trauma along with synergistic injury mechanisms that include rapid rotation of the brain, diffuse axonal injury, blunt force trauma, and hypoxia-ischemia make AHT challenging to treat. The anesthesiologist must understand the complex injury mechanisms inherent to AHT, as well as the pediatric TBI treatment guidelines, to decrease the risk of persistent neurologic disability and death. In this review, we discuss the epidemiology of AHT, differences between AHT and nonintentional TBI, the severe pediatric TBI treatment guidelines in the context of AHT, anesthetic considerations, and ethical and legal reporting requirements.

  6. Ballistics reviews: mechanisms of bullet wound trauma.

    PubMed

    Maiden, Nicholas

    2009-01-01

    The location of an entrance wound (bullet placement) and the projectile path are the most important factors in causing significant injury or death following a shooting. The head followed by the torso are the most vulnerable areas, with incapacitation resulting from central nervous system (brain or cord) disruption, or massive organ destruction with hemorrhage. Tissue and organ trauma result from the permanent wound cavity caused by direct destruction by the bullet, and also from radial stretching of surrounding tissues causing a temporary wound cavity. The extent of tissue damage is influenced by the type of bullet, its velocity and mass, as well as the physical characteristics of the tissues. The latter includes resistance to strain, physical dimensions of an organ, and the presence or absence of surrounding anatomical constraints. Bullet shape and construction will also affect tissue damage and bullets which display greater yaw will be associated with increased temporary cavitation. Military bullet designs do not include bullets that will expand or flatten as these cause greater wound trauma and are regulated by convention.

    Vascular trauma is associated with major morbidity and mortality, but little is known about its incidence or nature in Britain. A retrospective study of 36 patients requiring operative intervention for vascular trauma under one vascular surgeon over a 6-year period was undertaken. Twenty-four patients suffered iatrogenic trauma (median age 61 years); including cardiological intervention (19), radiological intervention (2), varicose vein surgery (1), umbilical vein catherisation (1) and isolated hyperthermic limb perfusion (1). There were 23 arterial and three venous injuries. Twelve patients had accidental trauma (median age 23 years). Three of the ten patients with blunt trauma were referred for vascular assessment before orthopaedic intervention, two after an on-table angiogram and five only after an initial orthopaedic procedure (range of delay 6 h to 10 days). Injuries were arterial in nine, venous in two and combined in one. Angiography was obtained in six patients, and in two patients with multiple upper limb fractures identified the site of injury when clinical localisation was difficult. A variety of vascular techniques were used to treat the injuries. Two patients died postoperatively and one underwent major limb amputation. Thirty-two (89%) remain free of vascular sequelae after a median follow-up of 48 months (range 3-72 months). Vascular trauma is uncommon in the United Kingdom. To repair the injuries a limited repertoire of vascular surgery techniques is needed. Therefore, vascular surgical assessment should be sought at an early stage to prevent major limb loss.

    Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygomatic fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter. As for the fractures of the frontal sinus a strong tendency towards minimized approaches can be seen. Obliteration and cranialization seem to decrease in numbers. Some critical remarks in terms of high dose methylprednisolone therapy for traumatic optic nerve injury seem to be appropriate. Intraoperative cone beam radiographs and preshaped titanium mesh implants for orbital reconstruction are new techniques and essential aspects in midface traumatology. Fractures of the anterior skull base with cerebrospinal fluid leaks show very promising results in endonasal endoscopic repair. PMID:26770280

    Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygoma fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter.

    Introduction Ostriches typically avoid humans in the wild, since they correctly assess humans as potential predators, and, if approached, often run away. However, ostriches may turn aggressive rather than run when threatened, especially when cornered, and may also attack when they feel the need to defend their offspring or territories. Presentation of case A 71-year-old male patient presented with intra abdominal injury sustained from being kicked in the abdominal wall by an ostrich. During laparotomy, were found free peritoneal effusion and perforation of the small intestine. Discussion The clinical history and physical examination are extremely important for diagnostic and therapeutic decision making. CT-scan is the most accurate exam for making diagnosis. Surgery is the treatment of choice, and is always indicated when there is injury to the hollow viscera. In general it is possible to suture the defect. Conclusion In cases of blunt abdominal trauma by animals is necessary to have a low threshold of suspicion for acute abdomen. PMID:25685344

  14. Exploring trauma associated appraisals in trauma survivors from collectivistic cultures.

    2016-01-01

    Appraisals are a key feature in understanding an individual's experience; this is especially important when the experience is a traumatic one. However, research is diminutive when looking at the interaction between trauma appraisals and culture in relation to posttraumatic stress disorder using qualitative methodologies. This study explored cultural differences in perceptions and appraisals of trauma using three qualitative focus groups with community members (n = 11) from collectivistic cultures who had experienced a traumatic event and three qualitative individual key informant interviews with mental health practitioners (n = 3) routinely working with trauma survivors. Using template analysis, eight emergent themes were highlighted from the data sets [(1) trauma and adjustment; (2) cultural and social roles; (3) traumatised self; (4) relationships; (5) external attribution; (6) future; (7) education; (8) language] that potentially have significant consequences for posttrauma psychological adjustment and recovery. Cumulatively, while a number of themes are similar to that which is emphasised in current literature (e.g. damaged self, negative appraisals of the world, others, future) a number of themes were also resonant and warrant further scrutiny. For instance, the importance and interconnectedness of the group to the individual and the impact trauma has on this; the importance of social roles, cultural appropriateness and violations of cultural values and norms; findings and implications are discussed.

    The mechanisms involved in traumatic brain injury have yet to be fully characterized. One mechanism that, especially in high-energy trauma, could be of importance is cavitation. Cavitation can be described as a process of vaporization, bubble generation, and bubble implosion as a result of a decrease and subsequent increase in pressure. Cavitation as an injury mechanism is difficult to visualize and model due to its short duration and limited spatial distribution. One strategy to analyze the cellular response of cavitation is to employ suitable in vitro models. The flyer-plate model is an in vitro high-energy trauma model that includes cavitation as a trauma mechanism. A copper fragment is accelerated by means of a laser, hits the bottom of a cell culture well causing cavitation, and shock waves inside the well and cell medium. We have found the flyer-plate model to be efficient, reproducible, and easy to control. In this study, we have used the model to analyze the cellular response to microcavitation in SH-SY5Y neuroblastoma, Caco-2, and C6 glioma cell lines. Mitotic activity in neuroblastoma and glioma was investigated with BrdU staining, and cell numbers were calculated using automated time-lapse imaging. We found variations between cell types and between different zones surrounding the lesion with these methods. It was also shown that the injured cell cultures released S-100B in a dose-dependent manner. Using gene expression microarray, a number of gene families of potential interest were found to be strongly, but differently regulated in neuroblastoma and glioma at 24 h post trauma. The data from the gene expression arrays may be used to identify new candidates for biomarkers in cavitation trauma. We conclude that our model is useful for studies of trauma in vitro and that it could be applied in future treatment studies. PMID:26869990

    2010-01-01

    The aim of biomechanics is the analysis of the structure and function of humans, animals, and plants by means of the methods of mechanics. Its foundations are in particular embedded in mathematics, physics, and informatics. Due to the inherent multidisciplinary character deriving from its aim, biomechanics has numerous connections and overlapping areas with biology, biochemistry, physiology, and pathophysiology, along with clinical medicine, so its range is enormously wide. This treatise is mainly meant to serve as an introduction and overview for readers and students who intend to acquire a basic understanding of the mathematical principles and mechanics that constitute the foundation of biomechanics; accordingly, its contents are limited to basic theoretical principles of general validity and long-range significance. Selected examples are included that are representative for the problems treated in biomechanics. Although ultimate mathematical generality is not in the foreground, an attempt is made to derive the theory from basic principles. A concise and systematic formulation is thereby intended with the aim that the reader is provided with a working knowledge. It is assumed that he or she is familiar with the principles of calculus, vector analysis, and linear algebra. PMID:21303323

    Deaths due to blunt force trauma to the head as a result of assault are some of the most common cases encountered by the practicing forensic pathologist. Previous studies have shown inflicting injury to the head region is one of the most effective methods of murder. The important factors that determine severity of trauma include the type of weapon used, type and site of skull fracture, intracranial haemorrhage and severity of brain injury. The aim of this study was to determine the characteristics of blunt force trauma to the skull produced by different instruments. Nine adult monkeys (Macaca fascicularis) skulls were used as models. Commonly found blunt objects comprising of Warrington hammer, hockey stick and open face helmet were used in this study. A machine calibrated force generator was used to hold the blunt object in place and to hit the skulls at forces of 12.5N and 25N. Resultant traumatic effects and fractures (linear, depressed, basilar, comminuted, and distastic) were analyzed according to type of blunt object used; surface area of contact and absolute force (N/cm(2)) delivered. Results showed that all investigated instruments were capable of producing similar injuries. The severity of trauma was not related to the surface area of contact with the blunt objects. However, only high absolute forces produced comminuted fractures. These findings were observational, as the samples were too small for statistical conclusions.

    A review of pediatric trauma focused on pediatric chest injuries was performed at a trauma center specializing in neurologic trauma. Eighty of 342 (23%) pediatric trauma patients admitted to the center had chest injuries. Age, gender, mechanism of injury, magnitude of injury, incidence of pulmonary infection, chest tube usage, endotracheal intubation, steroid or antibiotic usage, morbidity, and mortality data were reviewed. Sixteen of 78 children (20%) with chest injuries developed pulmonary infections and were compared with the noninfected group. Patients with pneumonia had a higher morbidity with significantly longer mean hospital stay (43.0 vs. 12.7 days; p = 0.001), duration of intubation (8.4 vs. 1.5 days; p = 0.001), and total days with chest tubes, (2.2 vs. 1.4 days; p = 0.02). Pneumonia was significantly associated with longer mean duration of steroid usage (6.4 vs. 0.8 days; p = 0.0001). Duration of steroid administration for the treatment of concomitant brain injury was a significant independent risk factor for the occurrence of pneumonia.

    2012-01-01

    Although the practice of medicine continually changes in response to new biomedical understanding, novel technologies, and evolving cultural contexts, the ethical foundations of the clinical relationship between patient and physician paradoxically remain constant. There are fundamental characteristics with respect to character, behavior, and responsibilities that are descriptive of and necessary to the role of healer and that underpin the notion of physicianship. This article discusses the underlying characteristics or virtues that are necessary to the practice of medicine from the perspectives of three different philosophic traditions: the Aristotelian idea of phronesis as developed in the work of Edmund Pellegrino; the notion of alterity as framed by Emmanuel Levinas; and the attributes necessary to healing as laid out in the kabbala.

    The study of the magnetic field of the Earth, or geomagnetism, is one of the oldest lines of scientific enquiry. Indeed, it has often been said that William Gilbert's De Magnete, published in 1600 and predating Isaac Newton's Principia by 87 years, can claim to be the first true scientific textbook; his study was essentially the first of academic rather than practical interest.What then, we may ask, has been accomplished in the nearly 400 intervening years up to the publication of Foundations of Geomagnetism? In short, a wealth of observational evidence, considerable physical understanding, and a great deal of mathematical apparatus have accrued, placing the subject on a much surer footing.The latter two categories are described in considerable detail, and with attendant rigor, in this book. The sphericity of the Earth means that a frequent theme in the book is the solution of the partial differential equations of electrodynamics in a spherical geometry.

    With increased awareness and liberal screening of trauma patients with identified risk factors, recent case series demonstrate improved early diagnosis of carotid artery trauma before they become problematio. There remains a need for unified screening criteria for both intracranial and extracranial carotid trauma. In the absence of contraindications, antithrombotic agents should be considered in blunt carotid artery injuries, as there is a significant risk of progression of vessel injury with observation alone. Despite CTA being used as a common screening modality, it appears to lack sufficient sensitivity. DSA remains to be the gold standard in screening. Endovascular techniques are becoming more widely accepted as the primary surgical modality in the treatment of blunt extracranial carotid injuries and penetrating/blunt intracranial carotid lessions. Nonetheless, open surgical approaches are still needed for the treatment of penetrating extracranial carotid injuries and in patients with unfavorable lesions for endovascular intervention.

    Traumatic injury to the pancreas is rare and difficult to diagnose. In contrast, traumatic injuries to the liver, spleen and kidney are common and are usually identified with ease by imaging modalities. Pancreatic injuries are usually subtle to identify by different diagnostic imaging modalities, and these injuries are often overlooked in cases with extensive multiorgan trauma. The most evident findings of pancreatic injury are post-traumatic pancreatitis with blood, edema, and soft tissue infiltration of the anterior pararenal space. The alterations of post-traumatic pancreatitis may not be visualized within several hours following trauma as they are time dependent. Delayed diagnoses of traumatic pancreatic injuries are associated with high morbidity and mortality. Imaging plays an important role in diagnosis of pancreatic injuries because early recognition of the disruption of the main pancreatic duct is important. We reviewed our experience with the use of various imaging modalities for diagnosis of blunt pancreatic trauma. PMID:24379625

    Little is known about the effects of developmental trauma on the neural basis of cognitive control among adults who do not have posttraumatic stress disorder. To examine this question, we used functional magnetic resonance imaging to compare the effect of subliminal priming with earthquake-related images on attentional control during a Stroop task in survivors of the 2008 Wenchuan earthquake in China (survivor group, survivors were adolescents at the time of the earthquake) and in matched controls (control group). We found that the survivor group showed greater activation in the left ventral anterior cingulate cortex (vACC) and the bilateral parahippocampal gyrus during the congruent versus incongruent condition, as compared to the control group. Depressive symptoms were positively correlated with left vACC activation during the congruent condition. Moreover, psychophysiological interaction results showed that the survivor group had stronger functional connectivity between the left parahippocampal gyrus and the left vACC than the control group under the congruent-incongruent condition. These results suggested that trauma-related information was linked to abnormal activity in brain networks associated with cognitive control (e.g., vACC-parahippocampal gyrus). This may be a potential biomarker for depression following developmental trauma, and it may also provide a mechanism linking trauma reminders with depression.

    According to the polyvagal theory, the autonomic nervous system can, in deviation from the conventional theory, be divided in three distinct parts that are in hierarchical relationship with each other. The most-primitive autonomic control results in depression of vital functions, the more evolved one in fighting or escape and the most evolved one in social involvement. Practical application of the polyvagal theory has resulted in positive results above all in the treatment of emotional trauma. in Finland, therapy of complex trauma is founded on the theory of structural dissociation of the personality, which together with the polyvagal theory forms a practical frame of reference for psychotherapeutic work.

    Trauma from widespread collective violence such as genocide and ethnic cleansing has not been discussed from a global perspective. It will be argued that the Western medical model of diagnostic labeling is inadequate for understanding victims of collective violence from around the world. Phenomenology and liberation philosophy will be discussed as alternatives to understanding trauma from collective violence that move beyond the Western medical model of diagnostic labeling. The insights gained from these alternative approaches will contribute to the development of nursing education, research, and practice relevant to the health of victims of collective violence around the globe.

    The modern understanding of the brain as a large, complex network of interacting elements is a natural consequence of the Neuron Doctrine [1,2] that has been bolstered in recent years by the tools and concepts of connectomics. In this abstracted, network-centric view, the essence of neural and cognitive function derives from the flows between network elements of activity and information - or, more generally, causal influence. The appropriate characterization of causality in neural systems, therefore, is a question at the very heart of systems neuroscience.

    Psychiatric disorders are excellent disease models in which gene-environmental interaction play a significant role in the pathogenesis. Childhood trauma has been known as a significant environmental factor in the progress of, and prognosis for psychiatric illness. Patients with refractory illness usually have more severe symptoms, greater disability, lower quality of life and are at greater risk of suicide than other psychiatric patients. Our literature review uncovered some important clinical factors which modulate response to treatment in psychiatric patients who have experienced childhood trauma. Childhood trauma seems to be a critical determinant of treatment refractoriness in psychotic disorder, bipolar disorder, major depressive disorder, and post-traumatic stress disorder. In patients with psychotic disorders, the relationship between childhood trauma and treatment-refractoriness appears to be mediated by cognitive impairment. In the case of bipolar disorder, the relationship appears to be mediated by greater affective disturbance and earlier onset, while in major depressive disorder the mediating factors are persistent, severe symptoms and frequent recurrence. In suicidal individuals, childhood maltreatment was associated with violent suicidal attempts. In the case of PTSD patients, it appears that childhood trauma makes the brain more vulnerable to subsequent trauma, thus resulting in more severe, refractory symptoms. Given that several studies have suggested that there are distinct subtypes of genetic vulnerability to childhood trauma, it is important to understand how gene-environment interactions influence the course of psychiatric illnesses in order to improve therapeutic strategies.

    Abstract: 25–35% of all seriously injured multiple trauma patients are coagulopathic upon arrival to the emergency department, and therefore early diagnosis and intervention on this subset of patients is important. In addition to standard plasma based tests of coagulation, the thromboelastogram (TEG®) has resurfaced as an ideal test in the trauma population to help guide the clinician in the administration of blood components in a goal directed fashion. We describe how thromboelastographic analysis is used to assist in the management of trauma patients with coagulopathies presenting to the emergency department, in surgery, and in the postoperative period. Indications for the utilization of the TEG® and platelet mapping as point of care testing that can guide blood component therapy in a goal directed fashion in the trauma population are presented with emphasis on the more common reasons such as massive transfusion protocol, the management of traumatic brain injury with bleeding, the diagnosis and management of trauma in patients on platelet antagonists, the utilization of recombinant FVIIa, and the management of coagulopathy in terminal trauma patients in preparation for organ donation. The TEG® allows for judicious and protocol assisted utilization of blood components in a setting that has recently gained acceptance. In our program, the inclusion of the perfusionist with expertise in performing and interpreting TEG® analysis allows the multidisciplinary trauma team to more effectively manage blood products and resuscitation in this population.

    Background: Prevention of primary damage caused by head trauma may be avoided with protective measures and techniques which is a public health concern. Experimental and clinical studies about treatment of head trauma were all centered to prevent secondary damage caused by physiopathological changes following primary injury. Neuroprotective features of tetracyclines were the focus of several experimental studies in the last decade. In the present study we aimed to investigate the neuroprotective effects of tetracycline in an experimental model of blunt brain injury in rats. Materials and Methods: 32 male Sprague-Dawley rats were divided into four experimental groups (n = 8). Head trauma was not performed in control group (group 1, craniectomy only). In the second group, head trauma and craniectomy were performed. Intraperitoneal saline was used in addition to trauma and craniectomy for treatment in group 3 whereas intraperitoneal tetracycline and saline were used for treatment in group 4. Results: When histological examinations performed by transmission electron microscopy were evaluated, injury at ultrastructural level was demonstrated to be less pronounced in tetracycline group with decreased lipid peroxidation levels. Conclusion: In accordance with these findings, we conclude that systemic tetracycline administration is effective in reduction of secondary brain damage and brain edema and thus it may be considered as a therapeutic option.

    PubMed

    Roberts, I

    2015-06-01

    Tranexamic acid (TXA) reduces blood loss by inhibiting the enzymatic breakdown of fibrin. It is often used in surgery to decrease bleeding and the need for blood transfusion. In 2011, results from a multi-center, randomized, and placebo-controlled trial (CRASH-2 trial) showed that TXA (1 g loading dose over 10 min followed by an infusion of 1 g over 8 h) safely reduces mortality in bleeding trauma patients. Initiation of TXA treatment within 3 h of injury reduces the risk of hemorrhage death by about one-third, regardless of baseline risk. Because it does not have any serious adverse effects, TXA can be administered to a wide spectrum of bleeding trauma patients. Limiting its use to the most severely injured or those with a diagnosis of 'hyperfibrinolysis' would result in thousands of avoidable deaths. A clinical trial (CRASH-3 trial) of TXA in patients with traumatic brain injury is now in progress.

    The trauma nurse leader role was developed by a group of trauma surgeons, hospital administrators, and emergency department and trauma leaders at Nationwide Children's Hospital who recognized the need for the development of a core group of nurses who provided expert trauma care. The intent was to provide an experienced group of nurses who could identify and resolve issues in the trauma room. Through increased education, exposure, mentoring, and professional development, the trauma nurse leader role has become an essential part of the specialized pediatric trauma care provided at Nationwide Children's Hospital.

    Penetrating head and neck trauma could cause significant mortality because of many important structures located in the brain and neck. Although high-velocity penetrating brain injury is often reported, reports of low-velocity, combined head and neck penetrating injury are rare. Hereby, the authors present a case of an old man who had encountered a serious accident, a 29-cm iron fork penetrated into his neck, through the skull base and into brain. After treatment by multidisciplinary team, the patient was in rehabilitation. The multidisciplinary team assists rapid diagnosis and treatment of penetrating neck and head injury is the key to ensure a good outcome. Therefore, as the authors face such patients again, a multidisciplinary team is needed. PMID:27428914

  8. Skeletal trauma in child abuse.

    2013-11-01

    Fractures and other skeletal injuries are common in childhood. Most are the result of falls, motor vehicle accidents, and other forms of accidental trauma. However, skeletal trauma is present in a significant number of abused children. Age and developmental abilities are key components in raising clinical suspicion for child abuse. Children who are unable to provide their own history because of age or developmental delay require increased attention. Younger children are more likely to have abusive fractures, whereas accidental fractures increase with age and developmental abilities. The consequences of missing abuse are high because children returned to their homes without intervention are likely to face further abuse and have an increased mortality risk. Because of the potentially high cost of undiagnosed child abuse, diagnosis of a skeletal injury is incomplete without diagnosing its etiology. All health providers for children should be able to recognize patterns of skeletal injury secondary to abusive trauma and understand the process for initiating Child Protective Services (CPS) investigations when necessary. Although they can occur accidentally, fractures in nonmobile children should always increase the clinician's concern for abusive trauma. In light of the significant consequences for children when abuse is missed by a primary care provider, abuse should be on the differential diagnosis for all presenting childhood injuries.

    Through 3 broad and interconnected streams of thought, resilience thinking has influenced the science of ecology and natural resource management by generating new multidisciplinary approaches to environmental problem solving. Resilience science, adaptive management (AM), and ecological policy design (EPD) contributed to an internationally unified paradigm built around the realization that change is inevitable and that science and management must approach the world with this assumption, rather than one of stability. Resilience thinking treats actions as experiments to be learned from, rather than intellectual propositions to be defended or mistakes to be ignored. It asks what is novel and innovative and strives to capture the overall behavior of a system, rather than seeking static, precise outcomes from discrete action steps. Understanding the foundations of resilience thinking is an important building block for developing more holistic and adaptive approaches to conservation. We conducted a comprehensive review of the history of resilience thinking because resilience thinking provides a working context upon which more effective, synergistic, and systems-based conservation action can be taken in light of rapid and unpredictable change. Together, resilience science, AM, and EPD bridge the gaps between systems analysis, ecology, and resource management to provide an interdisciplinary approach to solving wicked problems.

    The present study aims to compare quality of life of victims with long and short term post-traumatic amnesia and to analyze the relation between quality of life and length of amnesia, including or not the comatose period. This prospective cohort study, gathered data during the hospital stay and 3 and 6 months post- trauma. Blunt traumatic brain injury patients, over 14 years old, with no prior diagnosis of dementia or brain injury, admitted to a trauma center 12 hours post-trauma were included. The results were unfavorable among patients with long term amnesia. Correlation between length of post-traumatic amnesia and quality of life domains were more expressive when excluded comatose period, indicating that it must not be computed in the length of post-traumatic amnesia.

    Despite being the leading cause of death in the United States for individuals 46 years and younger and the primary cause of death among military service members, trauma care research has been underfunded for the last 50 years. Sustained federal funding for a coordinated national trauma clinical research program is required to advance the science of caring for the injured. The Department of Defense is committed to funding studies with military relevance; therefore, it cannot fund pediatric or geriatric trauma clinical trials. Currently, trauma clinical trials are often performed within a single site or a small group of trauma hospitals, and research data are not available for secondary analysis or sharing across studies. Data-sharing platforms encourage transfer of research data and knowledge between civilian and military researchers, reduce redundancy, and maximize limited research funding. In collaboration with the Department of Defense, trauma researchers formed the Coalition for National Trauma Research (CNTR) in 2014 to advance trauma research in a coordinated effort. CNTR's member organizations are the American Association for the Surgery of Trauma (AAST), the American College of Surgeons Committee on Trauma (ACS COT), the Eastern Association for the Surgery of Trauma (EAST), the Western Trauma Association (WTA), and the National Trauma Institute (NTI). CNTR advocates for sustained federal funding for a multidisciplinary national trauma research program to be conducted through a large clinical trials network and a national trauma research repository. The initial advocacy and research activities underway to accomplish these goals are presented.

    Because abnormal psychology courses presuppose a focus on pathological human functioning, nonpathologizing interventions within these classes are particularly powerful and can reach survivors, bystanders, and perpetrators. Interventions are needed to improve the social response to trauma on college campuses. By applying psychodynamic and feminist multicultural theory, instructors can deliver nonpathologizing interventions about trauma and trauma response within these classes. We recommend class-based interventions with the following aims: (a) intentionally using nonpathologizing language, (b) normalizing trauma responses, (c) subjectively defining trauma, (d) challenging secondary victimization, and (e) questioning the delineation of abnormal and normal. The recommendations promote implications for instructor self-reflection, therapy interventions, and future research.

    2013-01-01

    Approximately 70 to 80% of healthcare errors are due to poor team communication and understanding. High-risk environments such as the trauma setting (which covers a broad spectrum of departments in acute services) are where the majority of these errors occur. Despite the emphasis on interprofessional collaborative practice and patient safety, interprofessional teamworking in the trauma setting has received little attention. This paper presents the findings of a scoping review designed to identify the extent and nature of this literature in this setting. The MEDLINE (via OVID, using keywords and MeSH in OVID), and PubMed (via NCBI using MeSH), and CINAHL databases were searched from January 2000 to April 2013 for results of interprofessional teamworking in the trauma setting. A hand search was conducted by reviewing the reference lists of relevant articles. In total, 24 published articles were identified for inclusion in the review. Studies could be categorized into three main areas, and within each area were a number of themes: 1) descriptions of the organization of trauma teams (themes included interaction between team members, and leadership); 2) descriptions of team composition and structure (themes included maintaining team stability and core team members); and 3) evaluation of team work interventions (themes included activities in practice and activities in the classroom setting).Descriptive studies highlighted the fluid nature of team processes, the shared mental models, and the need for teamwork and communication. Evaluative studies placed a greater emphasis on specialized roles and individual tasks and activities. This reflects a multiprofessional as opposed to an interprofessional model of teamwork. Some of the characteristics of high-performing interprofessional teams described in this review are also evident in effective teams in the community rehabilitation and intermediate care setting. These characteristics may well be pertinent to other settings, and

    In the late 1980s the Dutch trauma surgeons (Dutch Trauma Society) expressed their concern about the quality of care to the (multi) trauma patients, in the prehospital as well as the in-hospital setting. The following intensive debate with the public health inspectorate and the government became the start point for major improvements in teaching and training (a.o. ATLS), reorganization, regionalization and implementation in which all partners in trauma care were involved. The regionalization of ambulance care, the introduction of mobile medical teams, the availability of trauma helicopters, the categorization of hospitals, the designation of trauma centres, the given responsibility of these centres in the regionalization of trauma care will and already have resulted in an important quality improvement, not only of the individual organizations but for all of the entire chain of trauma care. It has become a major step forward in the philosophy: get the individual trauma patient at the right time at the right hospital. Besides, initiatives have been taken to design a nationwide trauma registration data base in which all in-hospital trauma patients will be included. However serious concerns remain: shortage of intensive care beds, the impossibility to use the helicopter service at night, the shortage in the number of mobile medical teams at night and the slowness in executions of agreements between contracting parties. Many of the remaining problems are a matter of money. Not only (para) medical partners and hospitals but for all government and insurance companies should take their responsibility in this.

    Despite an annual trauma mortality of 5 million people worldwide, resulting in countless physical disabilities and enormous expenses, there are no standardized guidelines on trauma organization and management. Over the last few decades there have been very notorious improvements in severe trauma care, though organizational and economical aspects such as research funding still need to be better engineered. Indeed, trauma lags behind other serious diseases in terms of research and organization. The rapid developments in trauma care have produced original models available for research projects, initial resuscitation protocols and radiological procedures such as CT for the initial management of trauma patients, among other advances. This progress underscores the need for a multidisciplinary approach to the initial management and follow-up of this complicated patient population, where intensivists play a major role in both the patient admission and subsequent care at the trauma unit.

    Trauma care systems in Spain are provided by the Nacional Health Service in a decentralized way by the seventeen autonomous communities whose process of decentralization was completed in January 2002. Its organisation is similar in all of them. Public sector companies of sanitary emergencies look after the health of citizens in relation to medical and trauma emergencies with a wide range of up to date resources both technical and human. In the following piece there is a description of the emergency response teams divided into ground and air that are responsible for the on site care of the patients in coordination with other public services. They also elaborate the prehospital clinical history that is going to be a valuable piece of information for the teams that receive the patient in the Emergency Hospital Unit (EHU). From 1980 to 1996 the mortality rate per 10.000 vehicles and the deaths per 1.000 accidents dropped significantly: in 1980 6.4 and 96.19% and in 1996, 2.8 and 64.06% respectively. In the intrahospital organisation there are two differentiated areas to receive trauma patients the casualty department and the EHU. In the EHU the severe and multiple injured patients are treated by the emergency hospital doctors; first in the triage or resuscitation areas and after when stabilised they are passed too the observation area or to the Intensive Care Unit (ICU) and from there the EHU or ICU doctors call the appropriate specialists. There is a close collaboration and coordination between the orthopaedic surgeon the EHU doctors and the other specialists surgeons in order to comply with treatment prioritization protocols. Once the patient has been transferred an entire process of assistance continuity is developed based on interdisciplinary teams formed in the hospital from the services areas involved in trauma assistance and usually coordinated by the ICU doctors. There is also mentioned the assistance registry of trauma patients, the ICU professional training

    2004-01-01

    Introduction According to the literature, the increased recreational use of the snowmobile has resulted in an increasing number of musculoskeletal injuries. We wished to examine whether previously described risk factors continue to be associated with snowmobile trauma and to identify previously unrecognized risks and specific patterns of injury. Methods We carried out a chart review of all snowmobile-related injuries over a 10-year period at the Health Sciences Centre in Winnipeg, the only level 1 trauma centre serving the Province of Manitoba, with particular attention to the risk factors of suboptimal lighting, excessive speed and alcohol consumption. Results We identified 480 injuries in 294 patients, and 81 (27.6%) of these patients died. Collisions accounted for 72% of the injury mechanisms. Of the injuries sustained, 31% occurred on roads. Excessive speed was a risk factor in 54% of patients, suboptimal lighting in 86% and a blood alcohol level greater than 0.08 in 70%. Musculoskeletal injuries accounted for 57% of those recorded. There were also brachial plexus injuries (3%) and knee dislocations (2%). To our knowledge, this is the largest study detailing injury associated with recreational use of snowmobiles in Canada. Conclusions Because snowmobile trauma is caused principally by human errors, it is potentially preventable. Efforts aimed at prevention must focus on the driver, who controls the common risk factors. The danger of snowmobiling while intoxicated must be emphasized. Trail-side monitoring is likely to be ineffective, as the majority of accidents do not occur on designated snowmobile trails.

    Exposure to ionizing irradiation may affect brain functions directly, but may also change tissue sensitivity to a secondary insult such as trauma, stroke or degenerative disease. To determine if a low dose of particulate irradiation sensitizes the brain to a subsequent injury, C56BL6 mice were exposed to brain only irradiation with 0.5 Gy of 56Fe ions. Two months later, unilateral traumatic brain injury was induced using a controlled cortical impact system. Three weeks after trauma animals received multiple BrdU injections and 30 days later were tested for cognitive performance in the Morris water maze. All animals where able to locate the visible and hidden platform during training; however, treatment effects were seen when spatial memory retention was assessed in the probe trial (no platform). While sham and irradiated animals showed spatial memory retention, mice that received trauma alone did not. When trauma was preceded by irradiation, performance in the water maze was not different from sham-treated animals, suggesting that low dose irradiation had a protective effect in the context of a subsequent traumatic injury. Measures of hippocampal neurogenesis showed that combined injury did not induce any changes greater that those seen after trauma or radiation alone. After trauma there was a significant decrease in the percentage of neurons expressing the behaviorally-induced immediate early gene Arc in both hemispheres, without associated neuronal loss. After combined injury there were no differences relative to sham-treated mice. Our results suggest that combined injury resulted in decreased alterations of our endpoints compared to trauma alone. While the underlying mechanisms are not yet known, these results resemble a preconditioning, adaptive, or inducible-like protective response, where a sublethal or potentially injurious stimulus (i.e. irradiation) induces tolerance to a subsequent and potentially more damaging insult (trauma).

    This paper described the application of eye movement desensitization reprocessing (EMDR) for addressing the posttraumatic stress disorder (PTSD) symptoms in a Chinese woman who had experienced multiple traumas in her childhood. EMDR is an integrative therapeutic intervention that uses a standardized eight-phase approach to treatment. It is also a proven, effective, and efficient treatment for trauma. In this client with multiple traumas, the etiological event that lay the foundation of her dysfunctional responses was reprocessed first. The successful resolution of this event allowed the positive treatment effects to transfer to other traumatic events of a similar theme. This case also illustrates the importance of identifying a culturally appropriate positive cognition (PC) in contributing to the success of the treatment. PMID:22937416

    Among the initiatives to be found at UK universities is a vocational award with the title `University Foundation Degree' at Nottingham Trent University. This qualification will be offered in 14 different subjects including four in the Faculty of Science and Mathematics, in the areas of applied biology, applied sciences, chemistry and physics. The courses will be available on a two-year full-time, three-year sandwich or a part-time basis. Set at a higher standard and specification than the Higher National Diplomas which it replaces, the UFD has been devised in consultation with industry and will cover the technical and specialist areas demanded by employers to combat skills shortages. The UFD in applied sciences concentrates on practical applications through laboratory, IT and project work, supported by lectures and seminars. At the end students can enter the employment market or transfer onto the second year of a degree course. Science-based careers including research and development would be the aim of those taking the UFD in physics. The first year develops the fundamentals of modern physics supported by studies in mathematics, IT and computer programming, whilst year 2 is vocational in nature with industrial problem solving and work experience as well as an academic theme associated with environmental aspects of the subject. Those who complete the UFD will be allowed automatic progression to a specified honours degree course and would normally be expected to study for a further two years for this award. However, those demonstrating an outstanding academic performance can transfer to the linked degree programme at the end of the first year via fast-track modules. Back in May the UK's Quality Assurance Agency (QAA) announced new standard benchmarks for degrees. These will be introduced into higher education institutions from 2002 to outline the knowledge, understanding and skills a student should gain from a particular higher education course.

    Animals can be induced to resist cochlear damage associated with acoustic trauma by exposure to a variety of “conditioning” stimuli, including restraint stress, moderate level sound, heat stress, hypoxia, and corticosteroids. Here we identify in mice a corticosteroid-responsive transcription factor, PLZF (promyelocytic leukemia zinc finger protein), which mediates conditioned protection of the cochlea from acoustic trauma. PLZF mRNA levels in the cochlea are increased following conditioning stimuli, including restraint stress, dexamethasone administration, and moderate-to-high level acoustic stimulation. Heterozygous mutant (luxoid.Zbtb16LU/J) mice deficient in PLZF have hearing and responses to acoustic trauma similar to their wild type littermates but are unable to generate conditioning-induced protection from acoustic trauma. PLZF immunoreactivity is present in the spiral ganglion, lateral wall of the cochlea, and organ of Corti, all targets for acoustic trauma. PLZF is also present in the brain and PLZF mRNA in brain is elevated following conditioning stimuli. The identification of a transcription factor that mediates conditioned protection from trauma provides a tool for understanding the protective action of corticosteroids, which are widely used in treating acute hearing loss, and has relevance to understanding the role of corticosteroids in trauma protection.

    How are we to understand a child's development--both the potentiating and inhibiting factors? The past two decades have witnessed intensive research both on mental trauma and its possible effects on the child's developing brain, and on the importance of risk factors and protective factors in children's development and health. Research in these two fields has been conducted concurrently and has yielded new, important, and in many cases complementary, information. To promote the general availability and clinical applicability of these advances in our knowledge, it is necessary to modify our conceptual approach, basing it on the child's perspective instead.

    2016-01-01

    Hemorrhagic shock is a principal cause of death among trauma patients within the first 24 hours after injury. Optimal fluid resuscitation strategies have been examined for nearly a century, more recently with several randomized controlled trials. Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur. The randomized controlled trials examining restricted fluid resuscitation have demonstrated that aggressive fluid resuscitation in the prehospital and hospital setting leads to more complications than hypotensive resuscitation, with disparate findings on the survival benefit. Since the populations studied in each randomized controlled trial are slightly different, as is the timing of intervention and targeted vitals, there is still a need for a large, multicenter trial that can examine the benefit of hypotensive resuscitation in both blunt and penetrating trauma patients.

    Between July 1987 and December 1990 in Washington, DC, 116 patients sustained 146 fractures and seven dislocations due to an assault with a baseball bat. The ulna was the most common site of trauma (61 fractures), followed by the hand (27 injuries) and the radius (14 injuries). Forty-two of the 146 fractures were significantly displaced and required open reduction and internal fixation to restore satisfactory alignment. Twenty-nine of the 146 fractures were open fractures. Treatment protocol for open fractures consisted of irrigation and debridement, antibiotic therapy, and bone stabilization with either internal or external fixation, or casting. Recognition of the severity of the soft tissue and bone damage is important in the management of musculoskeletal trauma secondary to the baseball bat.

    In a review of over 300 CT scans of abdominal trauma, we encountered 13 patients with surgically proved pancreatic injuries. CT correctly diagnosed pancreatic fractures, contusions, or posttraumatic pseudocysts in 11 of these patients. There were two false positive and two false negative diagnoses. The CT diagnosis of pancreatic trauma may be difficult in selected patients who are scanned soon after injury. Acutely, the actual plane of a pancreatic fracture may be difficult to identify with CT, and the peripancreatic soft-tissue changes of traumatic pancreatitis are often subtle. Eight of 11 correctly diagnosed pancreatic injuries showed thickening of the left anterior renal fascia on CT scans. This sign should prompt a critical evaluation of the pancreas of the traumatized patient.

    Trauma is becoming a leading cause of death in most of the low-income and middle-income countries worldwide. The growing number of motor vehicles far surpasses the development and upkeep of the road and highway networks, traffic laws, and driver training and licensing. In Thailand, road traffic injuries have become the second leading cause of death and morbidity overall since 1990. The lack of improvement to existing roadways, implementation of traffic safety and ridership laws including seatbelt regulations, and poor emergency medical assistance support systems all contribute to these statistics. An insufficient number and inequitable distribution of healthcare professionals is also a national problem, especially at the district level. Prehospital care of trauma patients remains insufficient and improvements at the national level are suggested. PMID:18629597

    Summary Similar to penetrating torso trauma, nontorso injuries have undergone a fascinating oscillation between invasive and noninvasive approaches. This article discusses an organized approach to the evaluation and initial treatment of penetrating extremity injuries based on regional anatomy and clinical examination. The approach is reliable, efficient and minimizes both delays in diagnosis and missed injuries. Outpatient follow-up is particularly important for patients with extremity injuries who are discharged home from the emergency department. PMID:26022152

    During the past 6 years, 375 patients were hospitalized with injuries resulting from farm accidents. The mechanism of injury was farm animal in 135 patients (36%), tractor in 89 (24%), corn picker or auger in 57 (15%), power take-off in 29 (8%), other farm machinery in 50 (13%), and miscellaneous in 15 (4%). Injury severity score (ISS) of 25 or greater was calculated for 29 individuals (8%). Eleven groups of surgical subspecialists performed 539 procedures. Eight patients (2.1%) died as a result of their injuries. All eight deaths occurred after tractor accidents secondary to pelvic fractures, head and spinal cord injury, or blunt chest trauma. Thirty-nine patients (10%) were left with serious permanent disability. Unnecessary morbidity and mortality in many cases were attributed to excessive prehospital care times within a largely rural area. Better prevention by farmer education and the initiation of mandatory safety devices on agricultural equipment may lower the incidence of farm accidents. Major agricultural trauma is frequent and diverse and is optimally managed in a regional trauma center. PMID:4093573

    Nuclear medicine imaging procedures can play a significant role in evaluating the pulmonary complications that are seen in trauma patients. A quantitative method for measuring increased pulmonary capillary permeability that uses Tc-99m HSA allows early diagnosis of acute respiratory distress syndrome (ARDS) and accurately differentiates this condition from pneumonia or cardiogenic pulmonary edema. This technique may be of great value in following the response to therapy. The use of 133Xe to diagnose inhalation injury remains an important diagnostic tool, particularly at hospitals with specialized burn units. Regional decreases in ventilation-perfusion images reliably localize aspirated foreign bodies. Radionuclide techniques that are used to demonstrate gastropulmonary aspiration remain controversial and require further clinical evaluation. Pulmonary perfusion imaging, although nonspecific, may provide the earliest clue for correct diagnosis of fat embolism, air embolism, contusion, or laceration. Furthermore, the possibility of perfusion abnormality due to these uncommon conditions must be remembered whenever trauma patients are evaluated for pulmonary thromboembolism with scintigraphy. Occasionally, liver or spleen scintigraphy may be the most appropriate procedure when penetrating chest trauma also involves these subdiaphragmatic organs.

    Important advances have been made in the management of complex trauma through careful scientific analysis of outcomes. Outcomes analysis in combat extremity trauma is exemplified and highlighted by scholarly work in the treatment of catastrophic lower extremity trauma. The success of this line of research in civilian trauma is exemplified by the Lower Extremity Assessment Project (LEAP) study on the outcomes of civilian lower extremity trauma. This highly successful effort was followed by the Military Extremity Trauma Amputation/Limb Salvage (METALS) study. Current ongoing analysis of both the LEAP and METALS studies by the Major Extremity Trauma Research Consortium seeks to compare and contrast the similarities and differences of both studies and to advance evidence-based patient-centered care. The effects of psychological trauma on the injured individual underscore the global effect of severe trauma and the need for a multidisciplinary approach to trauma care. Statistical modeling is being used to analyze outcomes to further the ability to scientifically and definitively determine the best practices for patient care.

    Traumatic brain injury (TBI) is significant, from a public health standpoint, because it is a major cause of the morbidity and mortality of young people. Cerebral edema after a TBI, if untreated, can lead to devastating damage of the remaining tissue. The current therapies of severe TBI (sTBI), as outlined by the Brain Trauma Foundation, are often ineffective, thus a new method for the treatment of sTBI is necessary. Herein, the reduction of cerebral edema, after TBI, using an osmotic transport device (OTD) was evaluated. Controlled cortical impact (CCI) was performed on adult female CD-1 mice, and cerebral edema was allowed to form for 3 h, followed by 2 h of treatment. The treatment groups were craniectomy only, craniectomy with a hydrogel, OTD without bovine serum albumin (BSA), and OTD. After CCI, brain water content was significantly higher for animals treated with a craniectomy only, craniectomy with a hydrogel, and OTD without BSA, compared to that of control animals. However, when TBI animals were treated with an OTD, brain water content was not significantly higher than that of controls. Further, brain water content of TBI animals treated with an OTD was significantly reduced, compared to that of untreated TBI animals, TBI animals treated with a craniectomy and a hydrogel, and TBI animals treated with an OTD without BSA. Here, we demonstrate the successful reduction of cerebral edema, as determined by brain water content, after TBI using an OTD. These results demonstrate proof of principle for direct water extraction from edematous brain tissue by direct osmotherapy using an OTD.

    2004-12-01

    A model for personality dysfunction posits an interaction between inherited susceptibility and environmental factors such as childhood trauma. Core biological vulnerabilities in personality include dimensions of affective instability, impulsive aggression, and cognition/perceptual domains. For the dimension of impulsive aggression, often seen in borderline personality disorder (BPD), the underlying neurobiology involves deficits in central serotonin function and alterations in specific brain regions in the cingulate and the medial and orbital prefrontal cortex. The role of trauma in the development of personality disorder and especially for BPD remains unclear. Although recent studies suggest that BPD is not a trauma-spectrum disorder and that it is biologically distinct from posttraumatic stress disorder, high rates of childhood abuse and neglect do exist for individuals with personality dysfunction. Personality symptom clusters seem to be unrelated to specific abuses, but they may relate to more enduring aspects of interpersonal and family environments in childhood. Whereas twin and family studies indicate a partially heritable basis for impulsive aggression, studies of serotonin-related genes to date suggest only modest contributions to behavior. Gene-environment interactions involving childhood maltreatment are demonstrated in recent studies on antisocial behaviors and aggressive rhesus monkeys and highlight the need for further research in this important area.

    A previously healthy 34-year-old man sustained multiple skull fractures in a traffic accident. Radiological findings and visual field examination did not detect any abnormality. Shortly after the accident, he noticed blurred vision in both eyes. Six months after the accident, he gradually developed disturbance of visual acuity in the right eye. His best corrected visual acuity (BCVA) was 0.8 OD and 1.2 OS and brain MRI did not show any abnormality, while Humphrey visual field analysis demonstrated right homonymous hemianopsia. Two months after the initial presentation, his BCVA showed 0.1 OD and 0.08 OS. Visual field examination suggested that both right homonymous hemianopsia and left blind spot had become enlarged. Mitochondrial DNA analysis demonstrated G11,778A mutation and a diagnosis of Leber's hereditary optic neuropathy (LHON) was made. A few reports have documented mild acute insult to the head or blunt optic trauma as triggers of optic neuropathy in subjects with LHON. Although, the precise mechanism of LHON following trauma remains unknown, it appears that an acute insult may be sufficient to precipitate neuropathy in the optic nerve already compromised by mitochondrial dysfunction. Asymptomatic carriers should be advised to avoid possible precipitating factors such as head trauma.

    Background Although controversial, failing to consider the gravitational effects of head elevation on cerebral perfusion is speculated to increase susceptibility to rare, but devastating, neurologic complications after shoulder surgery in the beach chair position (BCP). We hypothesized that patients in the BCP have diminished cerebral blood flow autoregulation than those who undergo surgery in the lateral decubitus position (LDP). A secondary aim was to examine whether there is a relationship between patient positioning during surgery and postoperative cognition or serum brain injury biomarker levels. Methods Patients undergoing shoulder surgery in the BCP (n=109) or LDP (n=109) had mean arterial blood pressure (MAP) and regional cerebral oxygen saturation (rScO2) monitored with near-infrared spectroscopy. A continuous, moving Pearson’s correlation coefficient was calculated between MAP and rScO2, generating the variable cerebral oximetry index (COx). When MAP is in the autoregulated range, COx approaches zero because there is no correlation between cerebral blood flow and arterial blood pressure. In contrast, when MAP is below the limit of autoregulation, COx is higher because there is a direct relationship between lower arterial blood pressure and lower cerebral blood flow. Thus, diminished autoregulation would be manifest as higher COx. Psychometric testing was performed before surgery and then 7–10 days and 4–6 weeks after surgery. A composite cognitive outcome was determined as the Z-score. Serum S100β, neuron-specific enolase, and glial fibrillary acidic protein were measured at baseline, after surgery, and on postoperative day 1. Results After adjusting for age and history of hypertension, COx (p=0.035) was higher and rScO2 lower (p<0.0001) in the BCP group than in the LDP group. After adjusting for baseline composite cognitive outcome, there was no difference in Z-score 7 to 10 day (p=0.530) or 4 to 6 weeks (p=0.202) after surgery between the BCP and

    In the decades since Dr. John Caffey described a series of children with chronic subdural hematoma and long bone fractures, there has been a substantial increase in the medical recognition of various forms child abuse. In the United States, the term shaken baby syndrome was coined to explain a constellation of injuries assumed to be the result of violent shaking of infants. After improved understanding of the variety of mechanisms that occur when children are abused, abusive head trauma (AHT) has become the recommended terminology. AHT is a more comprehensive term that reflects the brain injuries that children suffer as the result of abuse. AHT continues to include shaking as a mechanism of injury as well as shaking with impact, impact alone, crushing injuries or combinations of several mechanisms. The medical community in the United States has led the way in developing new terminology and research to describe this unique and devastating form of abuse. The globalization of medicine and rapid information transfer has resulted in AHT becoming well-recognized internationally as a form of serious and fatal child abuse. This paper will review the historical basis in the United States for the diagnosis of AHT. We will also review some of the current international issue in epidemiology, diagnosis, legal processes and outcomes in selected countries/regions where child abuse physicians are actively involved in the evaluation of AHT.

    The social contexts in which the mass trauma of thousands of people occur and in which their recovery should progress have qualities that distinguish it in important ways from individualised trauma in which a person is a victim of a violent attack, rape or a traffic accident. Organised violence, such as wars, oppression by dictatorships and massive terrorist attacks are extreme cases in which hundreds or thousands of people are exposed to trauma in a short period of time. As such, it has multiple consequences that extend beyond the affected individuals and the symptoms they suffer. Although the symptoms may be similar, the social contexts in which individual victimisation and exposure to organised violence happen are very different. The social milieu in which the survivors of individual trauma and survivors of mass trauma are embedded is likewise different, with important consequences for recovery. Understanding the social context of the trauma helps create the right social intervention for healing at social and personal levels.

    Thyroid crisis, also known as thyroid storm, is a rare complication of thyrotoxicosis that results in a hypermetabolic and hyperadrenergic state. This condition requires prompt recognition and treatment because the mortality from thyroid crisis approaches 30%. Thyrotoxicosis alone will usually not progress to thyroid crisis. Thyroid crisis will typically be precipitated by some concomitant event such as infection, iodine-containing contrast agents, medications such as amiodarone, pregnancy, or surgery. Trauma is a rare precipitator of thyroid crisis. Several published studies have reported thyroid crisis resulting from blunt or penetrating neck trauma. Significant systemic trauma, such as motor vehicle accidents, has also been reported to precipitate thyroid crisis. It is very unusual for minor trauma to precipitate thyroid crisis. In the present study, we report the case of a patient who had incurred relatively minor maxillofacial trauma and developed thyroid crisis 2 weeks after the initial trauma. PMID:25085805

  7. The role of palliative care in trauma.

    PubMed

    Owens, Darrell

    2012-01-01

    Trauma remains a leading cause of morbidity and mortality in the United States. Despite the aggressive and heroic nature of trauma care, including trauma surgery, 10% to 20% of patients admitted to trauma intensive care units die. As the population continues to age, it is predicted that by 2050, approximately 40% of those experiencing traumatic injury will be older than 65 years. For multiple reasons, people in this age group who experience trauma are at greater risk for death. Palliative care is the specialty of health care that provides care for patients with serious, life-threatening, or life-limiting illness or injury, regardless of the stage of disease or treatment. The goal of palliative care is to reduce or alleviate suffering through expert pain and symptom management, as well as assistance with decision making. The integration of palliative and trauma care can assist and support patients and families through stressful, often life-changing times, regardless of the final outcome.

We demonstrate specific changes in localized brain activity consistent with their ability to generate at least two distinct mental states of self-awareness, each with its own access to autobiographical trauma-related memory. Our findings reveal the existence of different regional cerebral blood flow patterns for different senses of self. We present evidence for the medial prefrontal cortex (MPFC) and the posterior associative cortices to have an integral role in conscious experience.

    Although safety standards have reduced fatal head trauma due to single severe head impacts, mild trauma from repeated head exposures may carry risks of long-term chronic changes in the brain's function and structure. To study the physical sensitivities of the brain to mild head impacts, we developed the first dynamic model of the skull-brain based on in vivo MRI data. We showed that the motion of the brain can be described by a rigid-body with constrained kinematics. We further demonstrated that skull-brain dynamics can be approximated by an under-damped system with a low-frequency resonance at around 15 Hz. Furthermore, from our previous field measurements, we found that head motions in a variety of activities, including contact sports, show a primary frequency of less than 20 Hz. This implies that typical head exposures may drive the brain dangerously close to its mechanical resonance and lead to amplified brain-skull relative motions. Our results suggest a possible cause for mild brain trauma, which could occur due to repetitive low-acceleration head oscillations in a variety of recreational and occupational activities.

    Trauma exposure contributes to poor mental health among refugees, and exposure often is measured using a cumulative index of items from the Harvard Trauma Questionnaire (HTQ). Few studies, however, have asked whether trauma subtypes derived from the HTQ could be superior to this cumulative index in predicting mental health outcomes. A community sample of recently arrived Iraqi refugees (N = 298) completed the HTQ and measures of posttraumatic stress disorder (PTSD) and depression symptoms. Principal components analysis of HTQ items revealed a 5-component subtype model of trauma that accounted for more item variance than a 1-component solution. These trauma subtypes also accounted for more variance in PTSD and depression symptoms (12 and 10%, respectively) than did the cumulative trauma index (7 and 3%, respectively). Trauma subtypes provided more information than cumulative trauma in the prediction of negative mental health outcomes. Therefore, use of these subtypes may enhance the utility of the HTQ when assessing at-risk populations.

    Research in the area of psychological trauma raises a number of complex ethical issues. These include questions about unjustified medicalization of suffering, retraumatization of survivors, the morality of also investigating perpetrators of trauma, and neglecting to provide appropriate intervention. We discuss some of these issues against the backdrop of a study of trauma in South Africa, and the recent work of the Truth and Reconciliation Commission in that country. PMID:22033592

    Childhood trauma is believed to contribute to the development of borderline personality disorder (BPD), however the mechanism by which childhood trauma increases risk for specific symptoms of the disorder is not well understood. Here, we explore the relationship between childhood trauma, brain activation in response to emotional stimuli and psychotic symptoms in BPD. Twenty individuals with a diagnosis of BPD and 16 healthy controls were recruited to undergo a functional MRI scan, during which they viewed images of faces expressing the emotion of fear. Participants also completed the childhood trauma questionnaire (CTQ) and a structured clinical interview. Between-group differences in brain activation to fearful faces were limited to decreased activation in the BPD group in the right cuneus. However, within the BPD group, there was a significant positive correlation between physical abuse scores on the CTQ and BOLD signal in the midbrain, pulvinar and medial frontal gyrus to fearful (versus neutral) faces. In addition there was a significant correlation between midbrain activation and reported psychotic symptoms in the BPD group (P<0.05). These results show that physical abuse in childhood is, in individuals with BPD, associated with significantly increased activation of a network of brain regions including the midbrain in response to emotional stimuli. Sustained differences in the response of the midbrain to emotional stimuli in individuals with BPD who suffered childhood physical abuse may underlie the vulnerability of these patients to developing psychotic symptoms.

    Trauma management has evolved significantly in the past few decades thereby reducing mortality in the golden hour. However, challenges remain, and one such area is maxillofacial injuries in a polytrauma patient. Severe injuries to the maxillofacial region can complicate the early management of a trauma patient owing to the regions proximity to the brain, cervical spine, and airway. The usual techniques of airway breathing and circulation (ABC) management are often modified or supplemented with other methods in case of maxillofacial injuries. Such modifications have their own challenges and pitfalls in an already difficult situation. PMID:27162439

    Advances in information and communication technologies are changing the delivery of trauma care and education. Telemedicine is a tool that can be used to deliver expert trauma care and education anywhere in the world. Trauma is a rapidly-evolving field requiring access to readily available sources of information. Through videoconferencing, physicians can participate in continuing education activities such as Grand Rounds, seminars, conferences and journal clubs. Exemplary programs have shown promising outcomes of teleconferences such as enhanced learning, professional collaborations, and networking. This review introduces the concept of telemedicine for trauma education, and highlights efforts of programs that are utilizing telemedicine to unite institutions across the world. PMID:23531408

    2011-01-01

    The family members of death row inmates undergo unique suffering that includes disenfranchised grief and intense psychological trauma. In Texas, where executions occur at a rate of 1 every 2 weeks, this class of trauma victims presumably is large, a fact that should generate public mental health concern. Yet the class remains virtually unknown to the therapeutic community. Very little has been done to address the trauma healing needs of death row families. This theoretical paper proposes that structural therapy designed to reengage attachment relationships and reempower family members' innate resources to emotionally regulate one another may provide one of the most effective means of helping this population survive trauma.

  18. Red blood cell storage duration and trauma.

    PubMed

    Sparrow, Rosemary L

    2015-04-01

    Numerous retrospective clinical studies suggest that transfusion of longer stored red blood cells (RBCs) is associated with an independent risk of poorer outcomes for certain groups of patients, including trauma, intensive care, and cardiac surgery patients. Large multicenter randomized controlled trials are currently underway to address the concern about RBC storage duration. However, none of these randomized controlled trials focus specifically on trauma patients with hemorrhage. Major trauma, particularly due to road accidents, is the leading cause of critical injury in the younger-than-40-year-old age group. Severe bleeding associated with major trauma induces hemodynamic dysregulation that increases the risk of hypoxia, coagulopathy, and potentially multiorgan failure, which can be fatal. In major trauma, a multitude of stress-associated changes occur to the patient's RBCs, including morphological changes that increase cell rigidity and thereby alter blood flow hemodynamics, particularly in the microvascular vessels, and reduce RBC survival. Initial inflammatory responses induce deleterious cellular interactions, including endothelial activation, RBC adhesion, and erythrophagocytosis that are quickly followed by profound immunosuppressive responses. Stored RBCs exhibit similar biophysical characteristics to those of trauma-stressed RBCs. Whether transfusion of RBCs that exhibit storage lesion changes exacerbates the hemodynamic perturbations already active in the trauma patient is not known. This article reviews findings from several recent nonrandomized studies examining RBC storage duration and clinical outcomes in trauma patients. The rationale for further research on RBC storage duration in the trauma setting is provided.

    All cases of penetrating cardiac trauma in 1985 and 1986 in Jefferson County, Alabama, where patients dying of penetrating trauma received autopsies, were retrospectively reviewed. All hospitals in the county plus the single coroner's office provided the records of the 72 patients comprising this study. Incidents occurred most often in the home or residence (70%) by a known assailant (83%) due to domestic/social disputes (73%). Frequency was greatest in the evening hours (73% between 6:00 PM and 3:00 AM), on weekends in spring and summer. Victims tended to be male (86%), black (72%), married (46%), blue collar workers (62%). There were 41 (57%) gunshot wounds, 3 (4%) shotgun wounds, and 28 (39%) stab wounds with an associated mortality rate of 97%, 100%, and 68%, respectively. Prehospital mortality rate (dead at the scene) was 54.2% (39/72), and death on arrival was 26.4% (19/72), for a combined pretreatment mortality rate of 80.6%. All patients who arrived with no vital signs died. Mortality appeared to be related to mechanism of injury, age, race, sex, vital signs on arrival, number and specific cardiac chambers injured, associated major vascular injury, hematocrit, and mode of transportation. Mortality was not related to caliber of weapon, ethanol level, transport time, time from arrival to operation, or transfusion requirements. There were only ten survivors (1 gunshot wound and 9 stab wounds), all of whom had ventricular injuries and no associated major vascular injuries. The ten survivors represented a 71.4% (10/14) salvage rate for those victims arriving with vital signs. Complications occurred in three patients. Hospitalization averaged 7.3 days in the survivors. Penetrating cardiac trauma remains a serious, socially linked disease with a high rate of mortality. Rapid transport, aggressive resuscitation and cardiorrhaphy remain the best treatment.

Design Using a mixed-methods design, we developed and tested a Psychological Trauma item bank with patient and provider focus groups, cognitive interviews, and item response theory based analytic approaches, including tests of model fit, differential item functioning (DIF) and precision. Setting We tested a 31-item pool at several medical institutions across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Veterans Administration hospital. Participants A total of 716 individuals with SCI completed the trauma items Results The 31 items fit a unidimensional model (CFI=0.952; RMSEA=0.061) and demonstrated good precision (theta range between 0.6 and 2.5). Nine items demonstrated negligible DIF with little impact on score estimates. The final calibrated item bank contains 19 items Conclusion The SCI-QOL Psychological Trauma item bank is a psychometrically robust measurement tool from which a short form and a computer adaptive test (CAT) version are available.

    Neurodevelopment is a highly complex process, influenced by a wide range of interacting genetic and environmental factors. Recent developments in fetal, neonatal and infant behavioural genetics and brain imaging methods have allowed for more detailed investigation of the effects of early adverse environment on the developing brain. This review aims to provide background for neurobiological understanding of how the prolonged exposure to stress or trauma during early childhood affects subsequent cognitive, emotional and social development. Initially, a brief overview of brain development is provided - focusing, in particular, on the limbic system structures, which are closely linked to emotional experiences and reactions, learning and memory. Emphasis is placed on the concept of neural plasticity, which is the biological base of memory and learning - the two most important mechanisms through which the environment affects the behavior. Moreover, the concept of sensitive periods, that is to say periods of "vulnerability" or "opportunity" during which particular experiences affect brain growth, functional organization and maturation, is discussed. Brief overview of the neuroendocrine stress response system and the long-term effects of prolonged exposure to stress hormones on early brain development clarify further why children are more vulnerable than adults to the effects of stress. The section dealing with the memory, which is closely linked to the limbic system, attempts to discuss how early exposure to chronic stress or psychological trauma, through neurobiological effects and the process of learning, can lead to dysfunctional behaviors, which in its extreme form can be mental disorders. The two types of memory are discussed: (a) the implicit (nondeclarative), which develops during the prelingual stage of child's development and refers to unconscious memories of previous experiences, and (b) the explicit (declarative) memory, which is closely linked to language

Beside the use of fireworks and firearms, airbag ignitions and explosions caused by terror or suicidal acts are also relevant. Depending on duration and strength of the sound pressure affecting the human ear, isolated inner ear damage or additional ear drum perforation and interruption of the middle ear ossicle chain can result. By means of otoscopy, pure tone audiometry, measurement of otoacoustic emissions, and other neurootological examinations, the severity of the trauma can be determined. With prompt and adequate therapy, permanent hearing loss can be minimized. In particular, the measurement of otoacoustic emissions allows conclusions to be made on the functionality of the outer hair cells which are damaged first in most cases. Histological investigations on noise-exposed cochleas show extensive damage to the outer hair cells in the frequency range between 1.0 and 4.0 kHz, which correlates well with audiometric measurements.

    In the aftermath of a decade-long Maoist civil war in Nepal and the recent relocation of thousands of Bhutanese refugees from Nepal to Western countries, there has been rapid growth of mental health and psychosocial support programs, including posttraumatic stress disorder (PTSD) treatment, for Nepalis and ethnic Nepali Bhutanese. This medical anthropology study describes the process of identifying Nepali idioms of distress and local ethnopsychology and ethnophysiology models that promote effective communication about psychological trauma in a manner that minimizes stigma for service users. Psychological trauma is shown to be a multi-faceted concept that has no single linguistic corollary in the Nepali study population. Respondents articulated different categories of psychological trauma idioms in relation to impact upon the heart-mind, brain-mind, body, spirit, and social status, with differences in perceived types of traumatic events, symptom sets, emotion clusters, and vulnerability. Trauma survivors felt blamed for experiencing negative events, which were seen as karma transmitting past life sins or family member sins into personal loss. Some families were reluctant to seek care for psychological trauma because of the stigma of revealing this bad karma. In addition, idioms related to brain-mind dysfunction contributed to stigma while heart-mind distress was a socially acceptable reason for seeking treatment. Different categories of trauma idioms support the need for multidisciplinary treatment with multiple points of service entry. PMID:20309724

    While human plasma represents an attractive sample for disease biomarker discovery, the extreme complexity and large dynamic range in protein concentrations present significant challenges for characterization, candidate biomarker discovery, and validation. Herein, we describe a strategy that combines immunoaffinity subtraction and chemical fractionation based on cysteinyl peptide and N-glycopeptide captures with 2D-LC-MS/MS to increase the dynamic range of analysis for plasma. Application of this ''divide-and-conquer'' strategy to trauma patient plasma significantly improved the overall dynamic range of detection and resulted in confident identification of 22,267 unique peptides from four different peptide populations (cysteinyl peptides, non-cysteinyl peptides, N-glycopeptides, and non-glycopeptides) that covered 3654 nonredundant proteins. Numerous low-abundance proteins were identified, exemplified by 78 ''classic'' cytokines and cytokine receptors and by 136 human cell differentiation molecules. Additionally, a total of 2910 different N-glycopeptides that correspond to 662 N-glycoproteins and 1553 N-glycosylation sites were identified. A panel of the proteins identified in this study is known to be involved in inflammation and immune responses. This study established an extensive reference protein database for trauma patients, which provides a foundation for future high-throughput quantitative plasma proteomic studies designed to elucidate the mechanisms that underlie systemic inflammatory responses.

    Although safety standards have reduced fatal head trauma due to single severe head impacts, mild trauma from repeated head exposures may carry risks of long-term chronic changes in the brain's function and structure. To study the physical sensitivities of the brain to mild head impacts, we developed the first dynamic model of the skull–brain based on in vivo MRI data. We showed that the motion of the brain can be described by a rigid-body with constrained kinematics. We further demonstrated that skull–brain dynamics can be approximated by an under-damped system with a low-frequency resonance at around 15 Hz. Furthermore, from our previous field measurements, we found that head motions in a variety of activities, including contact sports, show a primary frequency of less than 20 Hz. This implies that typical head exposures may drive the brain dangerously close to its mechanical resonance and lead to amplified brain–skull relative motions. Our results suggest a possible cause for mild brain trauma, which could occur due to repetitive low-acceleration head oscillations in a variety of recreational and occupational activities.

    2012-01-01

    Evidence that trauma may play a role in the development of a psychotic illness has lead researchers to investigate the relationship between trauma and the content of attenuated psychotic symptoms. Participants in this study were considered to be at clinical high risk for developing psychosis by meeting criteria for attenuated positive symptom syndrome based on the Structured Interview for Prodromal Syndromes. Trained raters used a specifically designed codebook to identify content in the vignettes of 45 participants. Various types of trauma that had occurred before age 16 were assessed, where participants who endorsed more types of trauma were considered to have experienced a greater amount of trauma. Spearman rank correlations revealed significant positive relationships between increased trauma and feeling watched or followed (rho=0.38, p<0.05) and false beliefs of status or power (rho=0.31, p<0.04). Significant negative relationships were observed between increased trauma and hearing nonnegative voices (rho=−0.39, p<0.01) as well as having unusual negative thoughts surrounding the self (rho=−0.31, p<0.05). Although this was a small sample, these findings support the possibility of a meaningful relationship between experiences of trauma and the content of attenuated positive symptoms. PMID:23155365

  19. Partner preferences among survivors of betrayal trauma.

    Gobin, Robyn L

    2012-01-01

    Betrayal trauma theory suggests that social and cognitive development may be affected by early trauma such that individuals develop survival strategies, particularly dissociation and lack of betrayal awareness, that may place them at risk for further victimization. Several experiences of victimization in the context of relationships predicated on trust and dependence may contribute to the development of relational schema whereby abuse is perceived as normal. The current exploratory study investigates interpersonal trauma as an early experience that might impact the traits that are desired in potential romantic partners. Participants in the current study were asked to rate the desirability of several characteristics in potential romantic partners. Although loyalty was desirable to most participants regardless of their trauma history, those who reported experiences of high betrayal trauma rated loyalty less desirable than those who reported experiences of traumas that were low and medium in betrayal. Participants who reported experiences of revictimization (defined as the experience of trauma perpetrated by a close other during 2 different developmental periods) differed from participants who only reported 1 experience of high betrayal trauma in their self-reported desire for a romantic partner who possessed the traits of sincerity and trustworthiness. Preference for a partner who uses the tactic of verbal aggression was also associated with revictimization status. These preliminary findings suggest that victimization perpetrated by close others may affect partner preferences.

    The implementation of trauma systems has decreased the incidence of preventable death following injury and improved the quality of trauma care. Further improvements in outcome are unlikely to result from conventional therapies. Future strategies must include renewed interest in prevention and abrogation of secondary injury by modification of clinical protocols and manipulation of the inflammatory response by using molecular technologies.

    Handball has developed into a much faster and high-impact sport over the past few years because of rule changes. Fast sports with close body contact are especially prone to orofacial trauma. Handball belongs to a category of sports with medium risk for dental trauma. Even so, there is only little literature on this subject. The aim of this study was to examine the prevalence and the type of injuries, especially the occurrence of orofacial trauma, habits of wearing mouthguards, as well as degree of familiarity with the tooth rescue box. For this purpose, 77.1% (n=542/703) of all top athletes and coaches from the two highest Swiss leagues (National League A and National League B), namely 507 professional players and 35 coaches, were personally interviewed using a standardized questionnaire. 19.7% (n=100/507) of the players experienced dental trauma in their handball careers, with 40.8% (n=51/125) crown fractures being the most frequent by far. In spite of the relatively high risk of lip or dental trauma, only 5.7% (n=29/507) of the players wear mouthguards. The results of this study show that dental trauma is common among Swiss handball players. In spite of the high risk of dental trauma, the mouthguard as prevention is not adequately known, and correct procedure following dental trauma is rarely known at all. PMID:27622524

    Background Care in a trauma centre is associated with significant reductions in mortality after severe injury. However, emerging evidence suggests that outcomes across similarly accredited trauma centres are not equivalent, even after adjusting for case-mix. The primary objective of this analysis was to evaluate secular trends in overall mortality at trauma centres. Secondarily, we explored trauma centre-specific mortality to determine the extent of variation between centres. Methods Data on 26 421 adults (≥□18 yr) admitted to a trauma centre between 2005 and 2011 were derived from the Ontario Trauma Registry. We used generalized estimating equations to calculate in-hospital mortality over time and hierarchical models to estimate trauma-centre-specific mortality. To quantify variability between centres, we calculated median odds ratios. Adjusted odds of death were calculated for each trauma centre to identify those with higher than expected, average and lower than expected mortality. Results Overall mortality at trauma centres decreased from 13.2% in 2005 to 11.2% in 2009. After adjusting for case mix, the odds of death decreased by approximately 3% a year (95% confidence interval 0%–5%). Trauma centre-specific mortality ranged from 11.4% to 13.1%. After adjusting for case mix, differences in trauma centre-specific mortality were observed (median odds ratio = 1.25), suggesting that the odds of dying could be 1.25-fold greater if the same patient was admitted to 1 randomly selected trauma centre as opposed to another. Differences were most pronounced for patients with isolated head injuries and among older patients as evidenced by higher median odds ratios and the number of outliers. Interpretation We observed a significant improvement over time in the mortality of severely injured patients cared for at Ontario’s trauma centres. However, considerable differences in trauma centre–specific mortality were observed. Differences were most pronounced among

    Limb trauma is the most common among pediatric victims in earthquake. Compared with traumatic brain injury, which is frequent in earthquake, intracranial injury is rare, but it is the leading cause of death from trauma in earthquake. Thoracoabdominal crush injury, which often causes such crises as visceral hemorrhage, is also one of the main causes of death among pediatric victims in earthquake. Crush syndrome and osteofascial compartment syndrome are often complicated by acute renal failure. Because trauma is emergent in earthquake, the principle of "life-saving first, critical injury priority" should be complied with during on-site rescue. The injured children must be transferred to the medical center as soon as possible. It is essential to treat the critically injured children by multidisciplinary cooperation, and much attention should be paid to prevention of complications, rehabilitation care, and psychological counseling.

    Head injury commonly presents in association with torso or limb injuries, especially in blunt trauma mechanisms. Stopping life-threatening thoraco-abdominal hemorrhage and preventing secondary brain injury are time critical priorities. Although simultaneous operative management by multiple teams has been common practice in the recent wars in Iraq and Afghanistan, simultaneous surgery is rare in most civilian settings. Nevertheless, situations arise whereby simultaneous craniotomy and chest or abdominal surgery is necessary to prevent mortality or reduce severe morbidity. We discuss two recent cases at our level one trauma centre, the challenges that surgeons and the operating room staff face and propose that with appropriate planning this surgical capability can be integrated into the systems of contemporary advanced trauma units.

    Just as data from civilian trauma registries have been used to benchmark and evaluate civilian trauma care, data contained within the Joint Theater Trauma Registry (JTTR) present a unique opportunity to benchmark combat care. Using the iterative steps of the benchmarking process, we evaluated data in the JTTR for suitability and established benchmarks for 24-hour mortality in casualties with polytrauma and a moderate or severe blunt traumatic brain injury (TBI). Mortality at 24 hours was greatest in those with polytrauma and a severe blunt TBI. No mortality was seen in casualties with polytrauma and a moderate blunt TBI. Secondary insults after TBI, especially hypothermia and hypoxemia, increased the odds of 24-hour mortality. Data contained in the JTTR were found to be suitable for establishing benchmarks. JTTR data may be useful in establishing benchmarks for other outcomes and types of combat injuries.

    Traumatic brain injury (TBI) is a major global problem and affects approximately 10 million peoples annually; therefore has a substantial impact on the health-care system throughout the world. In this article, we have summarized various aspects of specific intensive care management in patients with TBI including the emerging evidence mainly after the Brain Trauma Foundation (BTF) 2007 and also highlighted the scope of the future therapies. This review has involved the relevant clinical trials and reviews (from 1 January 2007 to 31 March 2013), which specifically discussed about the topic. Though, BTF guideline based management strategies could provide standardized protocols for the management of patients with TBI and have some promising effects on mortality and morbidity; there is still need of inclusion of many suggestions based on various published after 2007. The main focus of majority of these trials remained to prevent or to treat the secondary brain injury. The future therapy will be directed to treat injured neurons and may benefit the outcome. There is also urgent need to develop some good prognostic indicators as well. PMID:24843345

    The objective of this study was to examine the relationships between combat related trauma, insomnia, and alcohol misuse. The author reviewed the standardized tests results from 39 active duty service members, all of whom had recent deployments to either Iraq or Afghanistan. The battery of self-test instruments assessed the effects of military trauma, anxiety, depression, alcohol use, and insomnia. Among the study subjects, the entire group reported significant sleep problems, with bedtime arousals impeding sleep initiation. Male subjects' reported an average AUDIT score of 8.62. Service members with higher trauma scores also reported greater misuse of alcohol. The high trauma scores also correlated with specific pre-sleep cognitive and somatic factors. The findings of this study lend support for the use of standardized instruments for assessing sleep problems, along with similar tests for trauma and substance misuse, which together should help identify high risk military patients.

    Kluft, Richard P

    2016-07-01

    The potential role of hypnosis in the treatment of trauma is both venerable and underappreciated. This article underscores the importance of the wounded-self concept by proposing a Kohutian perspective complimentary to the cognitively-driven model of Alladin (2014a, 2014b) discussed elsewhere in this issue. It explores selected topics that demonstrate (1) the importance of considering the wounds to the sense of self experienced by trauma victims and their implications for individualization of treatment in planning a psychotherapy; (2) the possibility of enhancing access to memories using shame alleviating techniques with minimal suggestive properties; (3) the use of hypnosis to facilitate less disruptive processing of traumatic materials; and (4) the importance of hypnosis in enhancing the safety of the trauma patient between sessions. Absent contraindications, the circumspect use of hypnosis as a facilitator of trauma treatment deserves consideration for inclusion in the mainstream of contemporary trauma treatment. PMID:27196011

    Aims: To study the impact of hypothermia upon admission to the Intensive Care Unit (ICU) on early and late mortality and to develop a prediction model for late mortality in severely injured trauma patients. Materials and Methods: A multicenter retrospective cohort study was performed in adult trauma patients admitted to the ICU of two Level-1 trauma centers between 2007 and 2012. Hypothermia was defined as a core body temperature of ≤35° Celsius. Logistic regression analyses were performed to quantify the effect of hypothermia on 24-hour and 28-day mortality and to develop a prediction model. Results: A total of 953 patients were included, of which 354 patients had hypothermia (37%) upon ICU admission. Patients were divided into a normothermic or hypothermic group. Hypothermia was associated with a significantly increased mortality at 24 hours and 28 days (OR 2.72 (1.18-6.29 and OR 2.82 (1.83-4.35) resp.). The variables included in the final prediction model were hypothermia, age, APACHE II score (corrected for temperature), INR, platelet count, traumatic brain injury and Injury Severity Score. The final prediction model discriminated between survivors and non-survivors with high accuracy (AUC = 0.871, 95% CI 0.844-0.898). Conclusions: Hypothermia, defined as a temperature ≤35° Celsius, is common in critically ill trauma patients and is one of the most important physiological predictors for early and late mortality in trauma patients. Trauma patients admitted to the ICU may be at high risk for late mortality if the patient is hypothermic, coagulopathic, severely injured and has traumatic brain injury or an advanced age.

    It is encouraging to see the much needed shift in the understanding and recognition of the concept of “burden of disease” in the context of traumatic injury. Equally important is understanding that the impact of trauma burden rivals that of nontraumatic morbidities. Subsequently, this paradigm shift reinstates the appeal for timely interventions as the standard for management of traumatic emergencies. Emergency trauma care in India has been disorganized due to inadequate sensitivity toward patients affected by trauma as well as the haphazard, nonuniform acceptance of standardization as the norm. Some of the major hospitals across various regions in the country do have trauma care units, but even those lack protocols to ensure that all trauma cases are handled by those units, largely owing to lack of structured referral system. As a first step to reform the state of trauma care in the country, a detailed overview is needed to gain insight into the prevailing reality. The objectives of this paper are to thus weave a foundation based on the statistical and qualitative burden of trauma in the country; the available infrastructure of trauma care centers equipped to deal with trauma; the need and scope of standardized protocols for intervention; and most importantly, the application of these in shaping educational initiatives in advancing emergency trauma care in the country.

    PubMed

    Chevignard, Mathilde P; Lind, Katia

    2014-12-01

    Abusive head trauma is a severe inflicted traumatic brain injury, occurring under the age of 2 years, defined by an acute brain injury (mostly subdural or subarachnoidal haemorrhage), where no history or no compatible history with the clinical presentation is given. The mortality rate is estimated at 20-25% and outcome is extremely poor. High rates of impairments are reported in a number of domains, such as delayed psychomotor development; motor deficits (spastic hemiplegia or quadriplegia in 15-64%); epilepsy, often intractable (11-32%); microcephaly with corticosubcortical atrophy (61-100%); visual impairment (18-48%); language disorders (37-64%), and cognitive, behavioral and sleep disorders, including intellectual deficits, agitation, aggression, tantrums, attention deficits, memory, inhibition or initiation deficits (23-59%). Those combined deficits have obvious consequences on academic achievement, with high rates of special education in the long term. Factors associated with worse outcome include demographic factors (lower parental socioeconomic status), initial severe presentation (e.g., presence of a coma, seizures, extent of retinal hemorrhages, presence of an associated cranial fracture, extent of brain lesions, cerebral oedema and atrophy). Given the high risk of severe outcome, long-term comprehensive follow-up should be systematically performed to monitor development, detect any problem and implement timely adequate rehabilitation interventions, special education and/or support when necessary. Interventions should focus on children as well as families, providing help in dealing with the child's impairment and support with psychosocial issues. Unfortunately, follow-up of children with abusive head trauma has repeatedly been reported to be challenging, with very high attrition rates. PMID:25501726

    Introduccion. La ciencia y la filosofia han abordado a lo largo de la historia del pensamiento y desde diferentes perspectivas epistemicas el problema mente-cerebro. La primera de ellas acota areas especificas de la realidad y construye hipotesis de corto alcance y multiple conectividad intercientifica con el objetivo de validar modelos teoricos; la segunda extiende su arquitectura sistemica al conjunto de lo real (incluida la actividad cientifica). Desarrollo. La complejidad del problema mente-cerebro exige generar un vinculo de conexion disciplinar entre la filosofia y la ciencia; nuestros presupuestos ontoepistemologicos se erigen, por lo tanto, en el marco de una filosofia orientada cientificamente (filosofia cientifica). Se defiende el materialismo emergentista como solucion filosofico-cientifica coherente y contrastable en contraposicion a otras propuestas desarrolladas desde diferentes modelos ontologicos (por ejemplo, dualismo interaccionista, funcionalismo, teoria de la identidad, epifenomenalismo...). Conclusiones. La respuesta al problema mente-cerebro solo es factible desde una neurociencia cognitiva fundamentada filosoficamente: el materialismo emergentista –postulado ontologico– afirma que la mente es una propiedad emergente (novedad cualitativa) del cerebro; el realismo cientifico –postulado epistemologico– sostiene que la neurociencia cognitiva es la herramienta teorico-experimental basica que posibilita el acceso cognoscitivo tanto al cerebro como a sus procesos neurocognitivos. Consideramos que a partir de esta fundamentacion filosofica, la neurociencia cognitiva adquiere legitimidad epistemica para acometer el estudio del proceso mental mas genuinamente humano: la conciencia.

    For the last 20 years, nonoperative management (NOM) of blunt hepatic trauma (BHT) has been the initial policy whenever this is possible (80% of cases), i.e., in all cases where the hemodynamic status does not demand emergency laparotomy. NOM relies upon the coexistence of three highly effective treatment modalities: radiology with contrast-enhanced computerized tomography (CT) and hepatic arterial embolization, intensive care surveillance, and finally delayed surgery (DS). DS is not a failure of NOM management but rather an integral part of the surgical strategy. When imposed by hemodynamic instability, the immediate surgical option has seen its effectiveness transformed by development of the concept of abbreviated (damage control) laparotomy and wide application of the method of perihepatic packing (PHP). The effectiveness of these two conservative and cautious strategies for initial management is evidenced by current experience, but the management of secondary events that may arise with the most severe grades of injury must be both rapid and effective.

    A prospective evaluation of all patients presenting with a sports-related ocular injury during a 1-year (4-season) period was conducted. Of the 202 patients evaluated, 28 (13.8%) required hospitalization and 11 (5.6%) required intraocular surgery. Twenty-six patients (12.8%) sustained permanent ocular sequelae including seven (3.5%) who suffered visual loss. Basketball accounted for 28.7%, baseball/softball 19.8%, and racquetball 11.4% of all injuries. At the time of injury, 5.1% of patients had worn protective eye wear, whereas on follow-up only 31% had used eye protection. These results indicate that sports trauma remains a significant cause of ocular morbidity.

    Exaggerated conditioned fear responses and impaired extinction along with amygdala overactivation have been observed in posttraumatic stress disorder (PTSD). These fear responses might be triggered by cues related to the trauma through higher-order conditioning, where reminders of the trauma may serve as unconditioned stimuli (US) and could maintain the fear response. We compared arousal, valence, and US expectancy ratings and BOLD brain responses using fMRI in 14 traumatized persons with PTSD and 14 without PTSD (NPTSD) and 13 matched healthy controls (HC) in a differential aversive conditioning paradigm. The US were trauma-specific pictures for the PTSD and NPTSD group and equally aversive and arousing for the HC; the conditioned stimuli (CS) were graphic displays. During conditioning, the PTSD patients compared to the NPTSD and HC indicated higher arousal to the conditioned stimulus that was paired with the trauma picture (CS+) compared to the unpaired (CS-), increased dissociation during acquisition and extinction, and failure to extinguish the CS/US-association compared to NPTSD. During early and late acquisition, the PTSD patients showed a significantly lower amygdala activation to CS+ versus CS- and a negative interaction between activation in the amygdala and dorsolateral prefrontal cortex (PFC), while NPTSD and HC displayed a negative interaction between amygdala and medial PFC. These findings suggest maladaptive anticipatory coping with trauma-related stimuli in patients with PTSD, indicated by enhanced conditioning, with related abnormal amygdala reactivity and connectivity, and delayed extinction.

    Non-accidental trauma (NAT) victims account for a significant percentage of our pediatric trauma population. We sought to better understand the injury patterns and outcomes of NAT victims who were treated at our level I pediatric trauma center. Trauma registry data were used to identify NAT victims between January 2008 and December 2012. Demographic data, injury severity, hospital course, and outcomes were evaluated. One hundred and eighty-eight cases of suspected NAT were identified. Children were mostly male and white. The median age was 1.1 years; the median Injury Severity Score was 9. Traumatic brain injuries, lower extremity fractures, and skull fractures were the most common injuries. Twenty-seven per cent required medical procedures; most were performed by orthopedic surgery. Twenty-four per cent required admission to the pediatric intensive care unit. The median length of stay was two days. The mortality rate was 9.6 per cent. We generated a hot spot map of our catchment area and identified areas of our state where NAT occurs at increased rates. NAT victims sustain significant morbidity and mortality. Due to the severity of injuries, pediatric trauma surgeons should be involved in the evaluation and management of these children. Much work is needed to prevent the death and disability incurred by victims of child abuse. PMID:26350656

    Background Trauma remains a leading cause of morbidity and mortality in resource limited countries. There is paucity of published reports on trauma care in Tanzania, particularly the study area. This study was carried out to describe our experiences in trauma management outlining the etiological spectrum, injury characteristics and treatment outcome of trauma patients at our local setting and compare our results with those from other centers in the world. Methods A descriptive prospective study of trauma patients was conducted at Bugando Medical Centre from April 2010 to March 2012. Statistical data analysis was done using SPSS software version 17.0. Results A total of 5672 trauma patients were enrolled in the study. The male to female ratio was 2.3: 1. The majority of patients were in the 2nd decade of life. Road traffic accident was the most common cause of trauma accounting for 60.7% of cases. The majority of patients (76.6%) sustained blunt injuries. Musculoskeletal (68.5%) and head/neck (52.6%) were the most frequent body region injured. Soft tissue injuries (open wounds) and fractures were the most common injuries accounting for 82.8% and 76.8% respectively. Majority of patients (74.4%) were treated surgically with wound debridement (94.0%) being the most frequently performed procedure. Postoperative complications were recorded in 31.5% of cases. The overall median duration of hospitalization was 26 days (range 1 day to 144 days). Mortality rate was 16.7%. Patients who had polytrauma, burn injuries and those who had tetanus and long bone fractures stayed longer in the hospital and this was statistically significant (P < 0.001), whereas the age > 65 years, severe trauma, admission Systolic Blood Pressure < 90 mmHg, presence of tetanus, severe head injury, the duration of loss of consciousness, the need for intensive care unit admission and finding of space occupying lesion on CT scan of the brain significantly influenced mortality (P < 0

    Repetitive transcranial magnetic stimulation (rTMS) is one form of non-invasive brain stimulation and increasingly shows neuroprotection in multiple neurological disorders. However, the potential of rTMS for protective action on auditory function following acoustic trauma has not been investigated. Here, we examined effect of TMS on hearing conservation, neurons survival and brain-derived neurotrophin factor (BDNF) expression in the cochlea and auditory cortex following acoustic trauma in rats. Wistar rats were exposed to intense pure tone noise (10 kHz, 120 dB SPL for 2 h) followed by rTMS treatment or sham treatment (handling control) daily for 14 days. Auditory brainstem response revealed there was no significant difference in hearing threshold shifts between rTMS- and sham-treated rats, although rTMS-treated rats showed less neuron loss in the auditory cortex in comparison with sham rats. Additionally, acoustic trauma increased BDNF expression in the cochlea and auditory cortex, and this elevation could be attenuated by rTMS treatment. Our results suggest present regiment of rTMS does not protect hearing against acoustic trauma, but maybe have implications for tinnitus treatment. PMID:27230393

  16. Addressing childhood trauma in a developmental context

    With the anticipated publication of the DSM-5 in May 2013, much reflection and work has been done on reviewing existing psychiatric nomenclature including, but not limited to the field of traumatic exposure. Traditionally, understanding of the psychiatric and psychological effects of trauma have been developed from studies with adults and then applied to trauma-exposed children with some modifications. While this is an important step to understanding the sequelae of trauma in children and adolescents, the adverse developmental effects of traumatic exposures on the rapidly evolving neurological, physical, social and psychological capacities of children calls for a developmentally sensitive framework for understanding, assessing and treating trauma-exposed children. The importance of early attachment relationships in infancy and childhood means that severely disrupted early caregiving relationships may have far-reaching and lifelong developmental consequences and can therefore be considered traumatic. Given the high rates of violence and trauma exposure of South African children and adolescents, the need for a developmentally based understanding of the effects of trauma on child and adolescent mental health becomes even more pronounced. In this paper, we draw on theoretical perspectives to provide a practical, clinically driven approach to the management of developmental trauma. PMID:25104963

    Deep vein thrombosis (DVT) and pulmonary embolism (PE) are known collectively as venous thromboembolism (VTE). Venous thromboembolic events are common and potentially life-threatening complications following trauma with an incidence of 5 to 63%. DVT prophylaxis is essential in the management of trauma patients. Currently, the optimal VTE prophylaxis strategy for trauma patients is unknown. Traditionally, pelvic and lower extremity fractures, head injury, and prolonged immobilization have been considered risk factors for VTE; however it is unclear which combination of risk factors defines a high-risk group. Modalities available for trauma patient thromboprophylaxis are classified into pharmacologic anticoagulation, mechanical prophylaxis, and inferior vena cava (IVC) filters. The available pharmacologic agents include low-dose heparin (LDH), low molecular weight heparin (LMWH), and factor Xa inhibitors. Mechanical prophylaxis methods include graduated compression stockings (GCSs), pneumatic compression devices (PCDs), and A-V foot pumps. IVCs are traditionally used in high risk patients in whom pharmacological prophylaxis is contraindicated. Both EAST and ACCP guidelines recommend primary use of LMWHs in trauma patients; however there are still controversies regarding the definitive VTE prophylaxis in trauma patients. Large randomized prospective clinical studies would be required to provide level I evidence to define the optimal VTE prophylaxis in trauma patients. PMID:22084663

    Using longitudinal data, the present study examined change in midlife neuroticism following trauma exposure. Our primary analyses included 670 participants (M(age) = 60.55; 65.22% male, 99.70% Caucasian) who completed the NEO Personality Inventory at ages 42 and 50 and reported their lifetime exposure to traumatic events approximately 10 years later. No differences in pre- and post-trauma neuroticism scores were found among individuals who experienced all of their lifetime traumas in the interval between the personality assessments. Results were instead consistent with normative age-related declines in neuroticism throughout adulthood. Furthermore, longitudinal changes in neuroticism scores did not differ between individuals with and without histories of midlife trauma exposure. Examination of change in neuroticism following life-threatening traumas yielded a comparable pattern of results. Analysis of facet-level scores largely replicated findings from the domain scores. Overall, our findings suggest that neuroticism does not reliably change following exposure to traumatic events in middle adulthood. Supplemental analyses indicated that individuals exposed to life-threatening traumas in childhood or adolescence reported higher midlife neuroticism than individuals who experienced severe traumas in adulthood. Life-threatening traumatic events encountered early in life may have a more pronounced impact on adulthood personality than recent traumatic events.

    To uncover causes of increased mortality rates in black accident victims, patterns of injury and access to trauma care were compared between black and white patients. Over a 41-month period (February 1985 to June 1988), 2120 white and 468 black patients, each with an Injury Severity Score (ISS) > 14 as a result of blunt trauma, were admitted to a Level I regional trauma center, part of a statewide trauma system. Blacks were significantly older and more of them had premorbid illnesses. Although vehicular crashes accounted for the majority of injuries in both groups, blacks had significantly more injuries resulting from falls, pedestrian accidents, and assaults. Whereas 70.6% of whites were transported from the scene and 73% were transported by helicopter, 52.7% of blacks were transported from the scene and 44% by helicopter. Blacks made up 18% of the study group and accounted for 20% of deaths (mortality rate 17.3% for blacks and 14.9% for whites). Mortality was significantly increased for black patients admitted with a Glasgow Coma Scale (GCS) score > or = 13. Private medical insurance, available for 46.3% of black patients, accounted for 78% of payments for all trauma admissions. Increased mortality of black trauma patients may be related to risk factors (age, premorbid illness), increased rates of pedestrian accidents and falls, and disparities in access to Level I trauma centers.

    Blunt pancreatic trauma is an uncommon injury but has high morbidity and mortality. In modern era of trauma care, pancreatic trauma remains a persistent challenge to radiologists and surgeons alike. Early detection of pancreatic trauma is essential to prevent subsequent complications. However early pancreatic injury is often subtle on computed tomography (CT) and can be missed unless specifically looked for. Signs of pancreatic injury on CT include laceration, transection, bulky pancreas, heterogeneous enhancement, peripancreatic fluid and signs of pancreatitis. Pan-creatic ductal injury is a vital decision-making parameter as ductal injury is an indication for laparotomy. While lacerations involving more than half of pancreatic parenchyma are suggestive of ductal injury on CT, ductal injuries can be directly assessed on magnetic resonance imaging (MRI) or encoscopic retrograde cholangio-pancreatography. Pancreatic trauma also shows temporal evolution with increase in extent of injury with time. Hence early CT scans may underestimate the extent of injures and sequential imaging with CT or MRI is important in pancreatic trauma. Sequential imaging is also needed for successful non-operative management of pancreatic injury. Accurate early detection on initial CT and adopting a multimodality and sequential imaging strategy can improve outcome in pancreatic trauma. PMID:26981225

    We aimed to investigate the correlation between the Glasgow Coma Scale (GCS), the injury severity score (ISS) and serum levels of trace elements (TE) in severe trauma patients to analyze alteration of the levels of trace elements and serum biochemical indexes in the period of admission from 126 adult cases of severe brain trauma with traffic accidents. Multi-trace elements for patients in the trauma-TE groups were used. The results indicated that all patients presented an acute trace elements deficiency syndrome (ATEDs) after severe trauma, and the correlation between ISS and serum levels of Fe, Zn, and Mg was significant. Compared to the normal control group, levels of the trace elements in serum were significantly decreased after trauma, suggesting that enhancement of immunity to infection and multiple organ failure (MOF) via the monitoring and supplement of trace elements will be a good strategy to severe traumatic patients in clinics.

  3. The philosophical foundations of Aleksandr R. Luria's neuropsychology.

    2003-12-01

    This article attempts to show that the cultural-historical psychological theory of Aleksandr R. Luria (Luriya) and his colleagues is based on the foundations of historical materialism. It argues in particular that Luria's psychology, neuropsychology, and brain theory are integrated in the same scientific research program and are based on the same philosophical premises, and that his theories must be interpreted in the Marxist context in which they are embedded. Luria's research program asserts that the development of higher mental functions depends on the appropriation of cultural means, particularly language, within social practice. Moreover, the brain structures underlying mental functions are also dependent on the appropriation of cultural means. Luria's clinical diagnosis and his program for rehabilitation of patients with brain lesions are based on his psychological theory and brain theory. The following analysis of Luria's comprehensive program will show that a socio-cultural non-reductive explanation of mental functions and their underlying brain structures may have implications for the philosophical discussion of the mind-brain problem.

    Chest radiographs frequently underestimate the severity and extent of chest trauma and, in some cases, fail to detect the presence of injury. CT is more sensitive than chest radiography in the detection of pulmonary, pleural, and osseous abnormalities in the patient who has chest trauma. With the advent of multidetector CT (MDCT), high-quality multiplanar reformations are obtained easily and add to the diagnostic capabilities of MDCT. This article reviews the radiographic and CT findings of chest wall, pleural, and pulmonary injuries that are seen in the patient who has experienced blunt thoracic trauma.

    Patients and their relatives are increasingly considered partners in health and social care decision-making. Numerous political drivers in the UK reflect a commitment to this partnership and to improving the experience of patients and relatives in emergency care environments. As a Lecturer/Practitioner in Emergency Care I recently experienced the London Trauma System as a relative. My dual perspective, as nurse and relative, allowed me to identify a gap in the quality of care akin to emotional intelligence. This paper aims to raise awareness of emotional intelligence (EI), highlight its importance in trauma care and contribute to the development of this concept in trauma nursing and education across the globe.

It is important to understand the anatomic and physiologic changes that occur during pregnancy. Accepted trauma guidelines for imaging and interventions should generally not be deviated from just because a patient is pregnant. Focus should be placed on injury prevention and education of at risk patients to decrease the morbidity and mortality associated with traumatic injuries in pregnant patients.

    It's been 30 years since an endovascular technique to control traumatic hemorrhage was first described. Despite major technical advances in both diagnostic and therapeutic technology, and a great deal of experience since then, endovascular techniques are rarely considered as part of frontline management for vascular trauma. This review considers the literature and calls for better planning and implementation of diagnostic and image=guided therapeutic facilities. Endovascular techniques should be an essential part of vascular trauma management along with endovascular specialists, partners in trauma teams.

  10. Mechanisms and prevention of secondary brain damage during intensive care.

    PubMed

    Dearden, N M

    1998-01-01

    The injured brain may be damaged by primary impact, secondary injury from secondary damage due to initiation of destructive inflammatory and biochemical cascades by the primary injury or secondary ischemic injury following secondary insults that initiate or augment these immunological and biochemical cascades. Cerebral ischemia will arise whenever delivery of oxygen and substrates to the brain fall below metabolic needs. Many factors lead to the development of secondary insults to the injured brain during initial resuscitation, transport, surgery, and subsequent intensive care. Continuous monitoring of cerebral oxygenation (jugular oximetry, brain tissue PO2) and cerebral blood flow velocity (transcranial Doppler ultrasonography) in patients with brain trauma reveals multiple episodes of transient hypoperfusion with an adverse relationship between incidence and outcome. Secondary brain insults arise through systemic or intracranial mechanisms that reduce cerebral blood flow from compromised CPP, vascular distortion or cerebrovascular narrowing or lower oxygen delivery from hypoxemia associated with airway obstruction, pulmonary pathology, or anemia. Secondary brain ischemia remains a common pathway to secondary brain damage in most critically ill neurosurgical patients. In the future prevention of secondary brain injury may well hinge on giving a cocktail of novel agents that modify destructive biochemical and inflammatory pathways, each having a potential therapeutic window possibly in a subgroup of patients. To date, phase 3 clinical trials of several agents including PEGSOD and tyrilizad mesylate have failed to show relevant efficacy after brain trauma or subarachnoid hemorrhage. The therapeutic role of calcium channel blockers in traumatic subarachnoid hemorrhage is currently under investigation following the results of subgroup metaanalysis. Several phase 3, NMDA receptor antagonist studies are underway in brain trauma with results expected soon. Although we

    Introduction The Pietermaritzburg Metropolitan Trauma Service (PMTS) has run a systematic quality improvement programme since 2006. A key component included the development and implementation of an effective surveillance system in the form of an electronic surgical registry (ESR). This study used data from the ESR to review the incidence, spectrum and outcome of paediatric trauma in Pietermaritzburg, South Africa. Methods The ESR was reviewed, and all cases of paediatric trauma managed between 1 January 2012 and 30 July 2014 were retrieved for analysis. Results During the study period, 1,041 paediatric trauma patients (724 male, 69.5%) were managed by the PMTS, averaging a monthly admission of 36. The mean age was 10.9 years (standard deviation: 5.4 years). The mechanism of injury (MOI) was blunt trauma in 753 patients (72.3%) and penetrating trauma in 170 (16.3%). Pedestrian vehicle collisions accounted for 21% of cases and motor vehicle collisions for a further 11%. Intentional trauma accounted for 282 patients (27.1%) and self-inflicted trauma for 14 cases (1.3%). Ninety patients admitted to the intensive care unit and fifty-one required high dependency unit admission. There were 17 deaths, equating to an in-hospital mortality rate of 1.7%. A total of 172 children died on the scene of an incident. There were 35 road traffic related deaths, 26 suicides by hanging, 27 deaths from blunt assault and 23 deaths from penetrating assault. The overall mortality rate for paediatric trauma was 18.2%. Conclusions The ESR has proved to be an effective surveillance system and has enabled the accurate quantification of the burden of paediatric trauma in Pietermaritzburg. This has improved our understanding of the mechanisms and patterns of injury, and has identified a high incidence of intentional and penetrating trauma as well as road traffic collisions. These data can be used to guide strategies to reduce the burden of paediatric trauma in our environment. PMID:26263934

    Background Craniomaxillofacial (CMF) fractures are typically treated with open reduction and internal fixation. Open reduction and internal fixation can be complicated by hardware exposure or infection. The literature often does not differentiate between these 2 entities; so for this study, we have considered all hardware exposures as hardware infections. Approximately 5% of adults with CMF trauma are thought to develop hardware infections. Management consists of either removing the hardware versus leaving it in situ. The optimal approach has not been investigated. Thus, a systematic review of the literature was undertaken and a resultant evidence-based approach to the treatment and management of CMF hardware infections was devised. Materials and Methods A comprehensive search of journal articles was performed in parallel using MEDLINE, Web of Science, and ScienceDirect electronic databases. Keywords and phrases used were maxillofacial injuries; facial bones; wounds and injuries; fracture fixation, internal; wound infection; and infection. Our search yielded 529 articles. To focus on CMF fractures with hardware infections, the full text of English-language articles was reviewed to identify articles focusing on the evaluation and management of infected hardware in CMF trauma. Each article’s reference list was manually reviewed and citation analysis performed to identify articles missed by the search strategy. There were 259 articles that met the full inclusion criteria and form the basis of this systematic review. The articles were rated based on the level of evidence. There were 81 grade II articles included in the meta-analysis. Result Our meta-analysis revealed that 7503 patients were treated with hardware for CMF fractures in the 81 grade II articles. Hardware infection occurred in 510 (6.8%) of these patients. Of those infections, hardware removal occurred in 264 (51.8%) patients; hardware was left in place in 166 (32.6%) patients; and in 80 (15.6%) cases

    The hypothalamic-pituitary-adrenal axis (HPA axis) is a pathway through which childhood trauma may increase risk for negative health outcomes. The HPA axis is sensitive to stress throughout development; however, few studies have examined whether timing of exposure to childhood trauma is related to differences in later HPA axis functioning. Therefore, we examined the association between age of first trauma and HPA axis functioning among adolescents, and whether these associations varied by sex. Parents of 97 youth (aged 9-16 years) completed the Early Trauma Inventory (ETI), and youth completed the Socially-Evaluated Cold-Pressor Task (SECPT). We measured salivary cortisol response to the SECPT, the cortisol awakening response, and diurnal regulation at home across 2 consecutive weekdays. Exposure to trauma during infancy related to delayed cortisol recovery from peak responses to acute stress, d = 0.23 to 0.42. Timing of trauma exposure related to diverging patterns of diurnal cortisol regulation for males, d = 0.55, and females, d = 0.57. Therefore, the HPA axis may be susceptible to developing acute stress dysregulation when exposed to trauma during infancy, whereas the consequences within circadian cortisol regulation may occur in the context of later trauma exposure and vary by sex. Further investigations are warranted to characterize HPA axis sensitivity to exposure to childhood trauma across child development.

    A better understanding of psychological trauma is fundamental to clinical psychology. Following traumatic event(s), a clinically significant number of people develop symptoms, including those of Acute Stress Disorder and/or Post Traumatic Stress Disorder. The trauma film paradigm offers an experimental psychopathology model to study both exposure and reactions to psychological trauma, including the hallmark symptom of intrusive memories. We reviewed 74 articles that have used this paradigm since the earliest review (Holmes & Bourne, 2008) until July 2014. Highlighting the different stages of trauma processing, i.e. pre-, peri- and post-trauma, the studies are divided according to manipulations before, during and after film viewing, for experimental as well as correlational designs. While the majority of studies focussed on the frequency of intrusive memories, other reactions to trauma were also modelled. We discuss the strengths and weaknesses of the trauma film paradigm as an experimental psychopathology model of trauma, consider ethical issues, and suggest future directions. By understanding the basic mechanisms underlying trauma symptom development, we can begin to translate findings from the laboratory to the clinic, test innovative science-driven interventions, and in the future reduce the debilitating effects of psychopathology following stressful and/or traumatic events.

    2010-12-01

    The ideal classification of spinal trauma does not yet exist, primarily because the combination of morphological, biomechanical and clinical parameters in one single nomenclature has proved impossible. For radiologists and surgeons who work closely together, only a few classifications of injury patterns have been shown to be useful enough to provide rapid and stable therapy decisions. Many classifications are too complex to be practical for day-to-day practice, such as the Magerl classification, which has been adopted by the Arbeitsgemeinschaft für Osteosynthesefragen (AO). Not least because of this classification difficulty, eponyms and synonyms are widely used to describe trauma of the spine, comparable to the number of terms used to describe fractures of the upper and lower limbs. The members of trauma teams should be aware of the definitions of these terms as well as the strengths and limitations of the existing classifications of spinal trauma. PMID:20967415

    How trauma victims remember--or forget--their most horrific experiences lies at the heart of the most bitter controversy in psychiatry and psychology in recent times. Whereas experts maintain that traumatic events--those experienced as overwhelmingly terrifying at the time of their occurrence--are remembered all too well, traumatic amnesia theorists disagree. Although these theorists acknowledge that trauma is often seemingly engraved on memory, they nevertheless maintain that a significant minority of survivors are incapable of remembering their trauma, thanks to mechanisms of either dissociation or repression. Unfortunately, the evidence they adduce in support of the concept of traumatic dissociative amnesia fails to support their claims. The purpose of this review is to dispel confusions and debunk myths regarding trauma and memory.

    Due to the prominent location of the nose, the most common facial traumas are nasal injuries. Although nasal traumas usually require staged intervention at a later period of time, in selected cases, primary reconstruction can be effective. A 20-year-old man who was referred from the emergency department with nasal trauma is presented. He reported a fall after feeling unsteady, which caused a direct nasal injury. Clinical examination revealed septal fracture with obstruction of the left nasal cavity and deformity of the nasal pyramid (inverted V deformity). The patient also had a complete dissection of the columella skin. Epistaxis was self-limited, and an open rhinoplasty procedure was decided because the trauma occurred 1 h before admission and there was no significant edema. Surgical intervention included septal reconstruction combined with restoration of the nasal pyramid and columella. One month later, the patient had patent nasal airways, and he was satisfied with the aesthetic result. PMID:22942663

This study explored their willingness to establish an Internet site for the purpose of commemorating the Holocaust as well as the materials and messages to be included. The results suggest that the younger members of a collective who live in a cultural atmosphere colored by the memory of a cultural trauma view online commemoration as an appropriate base from which to keep its memory alive, that audio-visual materials more so than textual ones are the preferred modes of representation, and that online commemoration is intended to provide a kaleidoscopic view of the trauma by focusing on the personal stories of both those who survived and those who perished.

    Popliteal-artery injuries in the paediatric-trauma patient are uncommon, difficult to diagnose and with prolonged ischaemia lead to substantial complications. We report three cases of popliteal-vasculature injury in paediatric-trauma patients with diverse mechanisms of injury: blunt trauma, penetrating injury and a Salter-Harris I fracture. We present a range of the significant sequelae that can result from paediatric popliteal-artery injury, both physically and psychologically. It is imperative that clinicians have a high index of suspicion when confronted with paediatric patients with trauma around the knee and that popliteal-vasculature injuries are diagnosed early. If insufficiencies are detected, further imaging should be considered, but surgical exploration should not be delayed in the presence of ischaemia.

    Our objective is to offer online real-tim e intelligent guidance to the neurosurgeon. Different from traditional image-guidance technologies that offer intra-operative visualization of medical images or atlas images, virtual brain counseling goes one step further. It can distinguish related brain structures and provide information about them intra-operatively. Virtual brain counseling is the foundation for surgical planing optimization and on-line surgical reference. It can provide a warning system that alerts the neurosurgeon if the chosen trajectory will pass through eloquent brain areas. In order to fulfill this objective, tracking techniques are involved for intra- operativity. Most importantly, a 3D virtual brian environment, different from traditional 3D digitized atlases, is an object-oriented model of the brain that stores information about different brain structures together with their elated information. An object-oriented hierarchical hyper-voxel space (HHVS) is introduced to integrate anatomical and functional structures. Spatial queries based on position of interest, line segment of interest, and volume of interest are introduced in this paper. The virtual brain environment is integrated with existing surgical pre-planning and intra-operative tracking systems to provide information for planning optimization and on-line surgical guidance. The neurosurgeon is alerted automatically if the planned treatment affects any critical structures. Architectures such as HHVS and algorithms, such as spatial querying, normalizing, and warping are presented in the paper. A prototype has shown that the virtual brain is intuitive in its hierarchical 3D appearance. It also showed that HHVS, as the key structure for virtual brain counseling, efficiently integrates multi-scale brain structures based on their spatial relationships.This is a promising development for optimization of treatment plans and online surgical intelligent guidance.

    Vertebral artery dissection is an important cause of brain stem stroke, especially in the young. Dissections of carotid and vertebral arteries in neck account for about 20% of strokes in young compared with 2.5% in the elderly. Three patients of vertebral artery dissection related to indirect neck trauma are described. The first patient developed the symptoms while dancing, the second after a trivial fall and the third while he was on a dental chair. None of them had a direct severe neck trauma or concomitant risk factor like hypertension, connective tissue disease or migraine. Clinical symptomatology was similar in all the patients and included occipito-nuchal pain, headache and brain stem dysfunction chiefly in the posterior inferior cerebellar artery (PICA) territory. One of the patients also had associated ischaemic myelopathy. MRA and DSA confirmed dissection in all with a predominant steno-occlusive picture. Cases of so called trivial neck movement/torsion related dissection have been described previously but have not received any major importance. Usually classified as 'spontaneous' or 'traumatic', there is a possible ambiguity in literature about appropriate terminology. We emphasise that a history of such subtle precipitating events be taken while diagnosing young patients with brain stem strokes, to recognise this clinical entity. Although mechanisms are not absolutely clear, yet there seems to be an important relationship between arterial dissection and neck movements or minor trauma. PMID:11799413

    Catecholamine surge after traumatic injury may lead to dysautonomia with increased morbidity. Small retrospective studies have shown potential benefit of beta-blockers (BB) in trauma patients with and without traumatic brain injury (TBI). This study evaluates a large multiply injured cohort without TBI that received BB. Patients were identified from the trauma registry from January 1, 2003 to December 31, 2011. Patients who received >1 dose of BB were compared to controls. Patients with TBI, length of stay (LOS) < 2 days, and prehospital BB were excluded. Outcomes were mortality, intensive care unit (ICU) LOS, and LOS. Stepwise multivariable regression was used to identify variables significantly associated with mortality. During the study period, 19,151 eligible patients were admitted. The mean age was 39 years. Most were male (74%) and most sustained blunt mechanism (75%). A total of 1854 (11%) patients received BB. BB patients had longer LOS (16 vs 6 days), ICU LOS (7 vs 1 days), and higher mortality (2.8 vs 0.5%) (all P < 0.001). Multivariable regression demonstrated no benefit to BB after adjusting for potential confounding characteristics [odds ratio (OR) 0.952; confidence interval (CI) 0.620-1.461]. In conclusion, in this largest study to date, patients receiving BB were older, more severely injured, and had a higher mortality. Unlike TBI patients, multivariable regression showed no benefit from BB in this population.

    Traumatic brain injury (TBI) is a frequent health problem and increased prevalence of neurendocrine dysfunction in patients with TBI has been reported. Sports injuries and particularly boxing may result in pituitary dysfunction. However, transient hypogonadotropic hypogonadism after an acute head trauma due to boxing and/or kickboxing has not been defined yet. We describe the case of a 20-yr-old male amateur kickboxer who was admitted to hospital complaining of decreased libido and impotence 2 weeks after an intensive bout. Basal hormone levels were compatible with mild hyperprolactinemia and hypogonadotpopic hypogonadism. GH axis was evaluated by GHRH+GHRP-6 test and peak GH level was within normal reference range. Three months later his complaints improved and abnormalities in basal hormone levels normalized. He was also re-evaluated 9 months after the first evaluation; basal hormone levels were within normal ranges and he had no complaints. In conclusion acute head trauma due to kickboxing may cause transient gonadotropin deficiency. Therefore, screening the pituitary functions of sportsmen dealing with combative sports is crucial.

    Arginine (ARG) is an amino acid (AA) with unique properties and with a key-role in the metabolic, immune and reparative response to trauma and sepsis. This study has been performed to characterize the correlations between plasma levels of ARG, of other AA and of multiple metabolic variables in trauma and sepsis. Two-hundred and sixty-three plasma amino-acidograms with a large series of additional biochemical and blood variables were obtained consecutively in 9 trauma patients who developed sepsis, undergoing total parenteral nutrition with dextrose, fat and a mixed AA solution containing 10.4% arginine. ARG was low soon after trauma, then it increased with increasing distance from trauma and with the development of sepsis. ARG was also directly related to the AA infusion rate (AAIR) and for any given AAIR, was lower after trauma than after the development of sepsis. ARG was also related directly to the plasma levels of most of the other AA, the best correlation being that with lysine (r(2) = 0.81, p < 0.001). These correlations were often shifted downwards (showing lower ARG for any given level of the other AA) in measurements performed after trauma, compared to those performed after development of sepsis; this effect was more pronounced for the correlations with branched chain AA. Correlations between ARG and non-AA variables were not particularly relevant. The best simultaneous correlates of ARG, among variables involved in plasma ARG availability, were citrulline level, AAIR and urinary 3-methylhistidine excretion (accounting for the effect of endogenous proteolysis) (multiple r(2) = 0.70, p < 0.001). Plasma ornithine (ORN), the AA more specifically linked to ARG metabolism, correlated with AAIR better than ARG and, for any given AAIR, was lower after trauma than after the development of sepsis. Correlations of ORN with other AA levels were poorer than those found for ARG, however ORN was directly related to white blood cell and platelet count, fibrinogen

    The technique of selective arterial embolisation for patients presenting with major hepatic trauma is described. We have used this technique successfully in four patients, three of whom had continued bleeding after emergency laparotomy. It can abolish localised intrahepatic arterial haemorrhage and arteriovenous shunting. Selective embolisation may prove to be a useful technique in reducing the mortality of major hepatic trauma.

    Blunt trauma to the epigastrum may result in a retroperitoneal hematoma involving the head of the pancreas and descending duodenum. Secondary effects include obstruction of the gastric outlet, obstruction of the biliary tree, and extrinsic compression of the inferior vena cava. Four patients with epigastric trauma were reviewed who had been examined by ultrasound of the abdomen. Ultrasound showed the extent of the retroperitoneal hematoma, its effect on contiguous organs, and was helpful in clinical management.

    Although the Chernobyl nuclear disaster happened in the Soviet Union in 1986, we still do not know how the most affected states - Ukraine and Belarus - have managed this tragedy since independence. Drawing on the concept of cultural trauma, this article compares Chernobyl narratives in Belarus and Ukraine over the past 28 years. It shows that national narratives of Chernobyl differ, representing the varying ways in which the state overcomes trauma. Our understanding of post-communist transformations can be improved by analysing trauma management narratives and their importance for new national identity construction. These narratives also bring new insights to our vision of cultural trauma by linking it to ontological insecurity. The article demonstrates how the state can become an arena of trauma process as it commands material and symbolic resources to deal with trauma. In general, it contributes to a better understanding of how the same traumatic event can become a source of solidarity in one community, but a source of hostility in another. PMID:27191056

    Trauma care has evolved rapidly over the past decade. The benefits of operative fracture management in major trauma patients are well recognised. Concerns over early total care arose when applied broadly. The burden of additional surgical trauma could constitute a second hit, fuelling the inflammatory response and precipitating a decline into acute respiratory distress syndrome, sepsis and multiple organ dysfunction syndrome. Temporary external fixation aimed to deliver the benefits of fracture stabilisation without the risk of major surgery. This damage control orthopaedics approach was advocated for those in extremis and a poorly defined borderline group. An increasing understanding of the physiological response to major trauma means there is now a need to refine our treatment options. A number of large scale retrospective reviews indicate that early definitive fracture fixation is beneficial in the majority of major trauma patients. It is recommended that patients are selected appropriately on the basis of their response to resuscitation. The hope is that this approach (dubbed 'safe definitive fracture surgery' or 'early appropriate care') will herald an era when care is individualised for each patient and their circumstances. The novel Damage Control in Orthopaedic Trauma Surgery course at The Royal College of Surgeons of England aims to equip senior surgeons with the insights and mindset necessary to contribute to this key decision making process as well as also the technical skills to provide damage control interventions when needed, relying on the improved techniques of damage control resuscitation and advances in the understanding of early appropriate care.

    Objective—To assess the complication rate of tube thoracostomy in trauma. To consider whether this rate is high enough to support a selective reduction in the indications for tube thoracostomy in trauma. Methods—A retrospective case series of all trauma patients who underwent tube thoracostomy during a 12 month period at a large UK teaching hospital with an accident and emergency (A&E) department seeing in excess of 125 000 new patients/year. These patients were identified using the hospital audit department computerised retrieval system supplemented by a hand search of both the data collected for the Major Trauma Outcome Study and the A&E admission unit log book. The notes were assessed with regard to the incidence of complications, which were divided into insertional, infective, and positional. Results—Fifty seven chest drains were placed in 47 patients over the 12 month period. Seven patients who died within 48 hours of drain insertion were excluded. The commonest indications for tube thoracostomy were pneumothorax (54%) and haemothorax (20%); 90% of tubes were placed as a result of blunt trauma. The overall complication rate of the procedure was 30%. There were no insertional complications and only one (2%) major complication, which was empyema thoracis. Conclusion—This study reveals no persuasive evidence to support a selective reduction in the indications for tube thoracostomy in trauma. A larger study to confirm or refute these findings must be performed before any change in established safe practice. PMID:10718232

    Research examining maladaptive responses to trauma routinely relies on spontaneous self-report to index intrusive thoughts, which assumes people accurately recognize and report their intrusive thoughts. However, "mind-wandering" research reveals people are not always meta-aware of their thought content: they often fail to notice shifts in their attention. In two experiments, we exposed subjects to trauma films, then instructed them to report intrusive thoughts during an unrelated reading task. Intermittently, we asked whether they were thinking about the trauma. As expected, subjects often spontaneously reported intrusive thoughts. However, they were also "caught" engaging in unreported trauma-oriented thoughts. The presence and frequency of intermittent probes did not influence self-caught intrusions. Both self-caught and probe-caught intrusions were related to an existing tendency toward intrusive cognition, film-related distress, and thought suppression attempts. Our data suggest people may lack meta-awareness of trauma-related thoughts, which has implications for theory, research and treatment relating to trauma-related psychopathology. PMID:24993526

    This study evaluates the otolith function of patients with head trauma, postulating that otolith dysfunction is a cause of nonspecific dizziness after head trauma. We prospectively enrolled 28 patients referred within 3 months after head trauma between March 2007 and December 2009. Pure tone audiometry, caloric testing and otolith function tests, including cervical vestibular evoked myogenic potential (cVEMP) and subjective visual vertical (SVV) tests, were performed on all patients. The relationship between otolith function and otologic symptoms was analyzed. Of the 28 patients with head trauma, 18 complained of dizziness and 12 experienced hearing loss, including 6 patients who complained of both. On defining otolith dysfunction as an abnormal cVEMP or abnormal SVV, a significant difference in otolith dysfunction existed between the groups with and without dizziness [72 (13/18) vs. 20% (2/10)]. In contrast, no significant difference in otolith dysfunction was detected between the abnormal and normal hearing groups. A significant number of the patients who complained of nonspecific dizziness after trauma had abnormal otolith function. After trauma, when patients complain of dizziness, vestibular function tests, including otolith function tests, should be considered.

    2013-07-01

    This article reviews the relationship between factors associated with resilience, and aspects of the individual's social ecology (environment) that promote and protect against the negative impact of exposure to traumatic events. It is shown that the Environment × Individual interactions related to resilience can be understood using three principles: (1) Resilience is not as much an individual construct as it is a quality of the environment and its capacity to facilitate growth (nurture trumps nature); (2) resilience looks both the same and different within and between populations, with the mechanisms that predict positive growth sensitive to individual, contextual, and cultural variation (differential impact); and (3) the impact that any single factor has on resilience differs by the amount of risk exposure, with the mechanisms that protect against the impact of trauma showing contextual and cultural specificity for particular individuals (cultural variation). A definition of resilience is provided that highlights the need for environments to facilitate the navigations and negotiations of individuals for the resources they need to cope with adversity. The relative nature of resilience is discussed, emphasizing that resilience can manifest as either prosocial behaviors or pathological adaptation depending on the quality of the environment.

    The thyroid function was analyzed for 4-6 weeks in a prospective study of 12 thermally injured patients. The burn size range was 15-90%. Serum concentrations of 3,5,3'-triidothyronine (T3) was suppressed and 3,3',5'-triidothyronine (rT3) was increased. The ratio T3/rT3 was subnormal on the third day after the trauma and normalized after 3 weeks. Thyroxine and the free T4-index were within the normal range. The free T3-index were within the normal range. The TSH concentration was initially low but slowly increasing during the period of study. The concentration of the thyroxine-binding globulin (TBG) varied within the normal range. The T3 resin uptake test varied inversely with the TBG concentration. The concentration of thyroxine-binding prealbumin (TBPA) was subnormal. A control experiment excluded possible interference on the hormone concentrations of administered donor blood and plasma. It is concluded that the thyroid hormones are not responsible for the posttraumatic hypermetabolism in burn injury. The present findings further indicate a depletion of metabolically active thyroid hormones at the cellular level after burn injury. PMID:6803354
