    The relationship between whiplash trauma and chronic orofacial pain is unclear, especially with regard to the time elapsed from trauma to development of orofacial pain. The aim was to analyze prevalence of jaw pain and disability, as well as the relationship between pain and disability in the jaw and neck regions in the early nonchronic stage after whiplash trauma. In this case-control study, 70 individuals (40 women, 30 men, mean age 35.5 y) who visited an emergency department with neck pain following a car accident were examined within 3 wk of trauma (group 1) and compared with 70 individuals (42 women, 28 men, mean age 33.8 y), who declined to attend a clinical examination but agreed to fill in questionnaires (group 2). The 2 case groups were compared with a matched control group of 70 individuals (42 women, 28 men, mean age 37.6 y) without a history of neck trauma. All participants completed questionnaires regarding jaw pain and dysfunction, rating pain intensity in jaw and neck regions on the Numerical Rating Scale, the Neck Disability Index, and Jaw Disability Checklist. Compared with controls, individuals with a recent whiplash trauma reported more jaw pain and dysfunction. Furthermore, there was a moderate positive correlation between jaw and neck pain ratings for group 1 (r = 0.61, P < 0.0001) and group 2 (r = 0.59, P < 0.0001). In the logistic regression analysis, cases showed higher odds ratios (range, 6.1 to 40.8) for jaw and neck pain and disability compared with controls. Taken together, the results show that individuals with a recent whiplash trauma report more jaw pain and disability compared with controls without a history of neck trauma. Furthermore, the correlation between jaw and neck pain intensity implies that intensity of neck pain in the acute stage after whiplash trauma might be a possible risk factor also for development of chronic orofacial pain.

    Background 10–22% of individuals sustaining whiplash trauma develop persistent symptoms resulting in reduced working ability and decreased quality of life, but it is poorly understood why some people do not recover. Various collision and post-collision risk factors have been studied, but little is known about pre-collision risk factors. In particular, the impact of sickness and socioeconomic factors before the collision on recovery is sparsely explored. The aim of this study was to examine if welfare payments received within five years pre-collision predict neck pain and negative change in provisional situation one year post-collision. Methods and Findings 719 individuals with acute whiplash trauma consecutively recruited from emergency departments or primary care after car accidents in Denmark completed questionnaires on socio-demographic and health factors immediately after the collision. After 12 months, a visual analogue scale on neck pain intensity was completed. 3595 matched controls in the general population were sampled, and national public register data on social benefits and any other welfare payments were obtained for participants with acute whiplash trauma and controls from five years pre-collision to 15 months after. Participants with acute whiplash trauma who had received sickness benefit for more than 12 weeks pre-collision had increased odds for negative change in future provisional situation (Odds Ratio (OR) (95% Confidence Interval (CI) = 3.8 (2.1;7.1)) and future neck pain (OR (95%CI) = 3.3 (1.8;6.3)), controlling for other known risk factors. Participants with acute whiplash trauma had weaker attachment to labour market (more weeks of sick leave (χ2(2) = 36.7, p < 0.001) and unemployment (χ2(2) = 12.5, p = 0.002)) pre-collision compared with controls. Experiencing a whiplash trauma raised the odds for future negative change in provisional situation (OR (95%CI) = 3.1 (2.3;4.4)) compared with controls. Conclusions Sick leave before the

    Background Previous clinical studies have documented successful neck pain relief in whiplash patients using nerve block and radiofrequency ablation of facet joint afferents, including capsular ligament nerves. No previous study has documented injuries to the neck ligaments as determined by altered dynamic mechanical properties due to whiplash. The goal of the present study was to determine the dynamic mechanical properties of whiplash-exposed human cervical spine ligaments. Additionally, the present data were compared to previously reported control data. The ligaments included the anterior and posterior longitudinal, capsular, and interspinous and supraspinous ligaments, middle-third disc, and ligamentum flavum. Methods A total of 98 bone-ligament-bone specimens (C2–C3 to C7-T1) were prepared from six cervical spines following 3.5, 5, 6.5, and 8 g rear impacts and pre- and post-impact flexibility testing. The specimens were elongated to failure at a peak rate of 725 (SD 95) mm/s. Failure force, elongation, and energy absorbed, as well as stiffness were determined. The mechanical properties were statistically compared among ligaments, and to the control data (significance level: P < 0.05; trend: P < 0.1). The average physiological ligament elongation was determined using a mathematical model. Results For all whiplash-exposed ligaments, the average failure elongation exceeded the average physiological elongation. The highest average failure force of 204.6 N was observed in the ligamentum flavum, significantly greater than in middle-third disc and interspinous and supraspinous ligaments. The highest average failure elongation of 4.9 mm was observed in the interspinous and supraspinous ligaments, significantly greater than in the anterior longitudinal ligament, middle-third disc, and ligamentum flavum. The average energy absorbed ranged from 0.04 J by the middle-third disc to 0.44 J by the capsular ligament. The ligamentum flavum was the stiffest ligament, while the

    Spinal injury following inertial loading of the head and neck (whiplash) is a common sequel of low speed traffic crashes. A variety of non-musculoskeletal injuries have been described in association with injury to the spine following whiplash trauma, including traumatic brain injury, vestibular derangement, and cranial nerve injury, among others. Vascular injuries in the head and neck have, however, only rarely been described. We present the case of a middle-aged male who sustained an ultimately fatal injury that resulted from injury to the internal carotid artery (ICA) and intracerebral vascular structures following a hard braking maneuver, with no direct head- or neck contact with the vehicular interior. Based on this unusual mechanism of injury we reviewed hospital data from the United States nationwide inpatient database (NIS) to assess the frequency of similar injuries reportedly resulting from traffic crashes. The post-mortem examination revealed a left internal carotid artery dissection associated with subarachnoid hemorrhage (SAH). Based on the close temporal association, the absent prior history, and the plausibility of the injury mechanism, the injury was attributed to the braking maneuver. An analysis of NIS data demonstrated that the prevalence of subarachnoid hemorrhage is significantly higher when there is a traumatic etiology, and higher yet when the trauma is a traffic crash (odds ratio 3.3 and 4.3, respectively). The presented case, together with the hospital inpatient data analysis, indicate that although SAH in combination with ICA dissection is relatively rare, it is substantially more probable following a traffic crash. In a clinical or forensic setting the inference that magnitude of a trauma was low should not serve as a basis for either excluding a cervical artery dissection from a differential diagnosis, or for excluding the trauma as a cause of a diagnosed dissection. This case report illustrates a rare fatal outcome of inertial load to

    Objective Individuals exposed to whiplash collisions have to cope with the stressful event as well as early physical symptoms. As in other chronic pain conditions, coping has been associated with outcome after whiplash. In this study, our aim was to examine whether initial coping preferences were associated with the development of chronic whiplash. Design Prospective study. Setting Primary care. Methods 740 acute whiplash patients were recruited from emergency units and general practitioners after car collisions in Denmark. Within 10 days postinjury, participants were asked what they believed could help them get better. At 12-month follow-up, the level of neck pain and capability to work was obtained. Whether coping preferences (baseline) were associated with outcome was investigated using multiple regression analyses. Results Persistent neck pain was most strongly associated with preferring medications (mean difference=1.24 (95% CI 0.67 to 1.82)) and sickness absence (mean difference=1.18 (95% CI 0.53 to 1.82)). Reduced work capability was most strongly associated with preferring medications (OR=3.53 (95% CI 2.13 to 5.86)), sickness absence (OR=3.05 (95% CI 1.80 to 5.17)) and being referred to a physiotherapist/chiropractor (OR=3.03 (95% CI 1.33 to 6.91)). Active coping was associated with better outcomes: Participants preferring to change their lifestyle were protected against reduced work capability (OR=0.11 (95% CI 0.01 to 0.78)). Individuals who wanted to keep living as usual only (no other preference reported) were protected against neck pain (mean difference −1.62 (95% CI −2.39 to −0.84)) and reduced work capability (OR=0.09 (95% CI 0.01 to 0.64)). Conclusions A simple nine-item measure of coping preferences is associated with the development of chronic neck pain and reduced capability to work following whiplash trauma and may be used to identify individuals at risk of poor recovery.

    Patients with acute whiplash-associated disorder (WAD) demonstrate an inefficient endogenous pain inhibition and may experience a dysfunction in autonomic nervous system reactivity to pain. This study compared the autonomic response to painful stimuli between patients with acute and chronic WAD and healthy controls. In addition, the role of the autonomic nervous system for explaining inefficient endogenous pain inhibition was examined in acute WAD. Seventeen patients with acute WAD, 30 patients with chronic WAD, and 31 healthy controls participated in an experiment evaluating the autonomic nervous system at rest and during painful stimuli. Skin conductance and heart rate variability (HRV) parameters were monitored continuously during conditioned pain modulation. A significant autonomic response to pain was present for skin conductance and two HRV parameters in all experimental groups. There was an interaction effect in the skin conductance response to pain but not in HRV responses in any of the groups. In patients with acute WAD, no significant correlations were present between pain, pressure pain thresholds, pain inhibition, and any of the autonomic parameters. This study refutes autonomic dysfunction at rest and in response to pain in acute WAD. The dysfunctional conditioned pain modulation appears unrelated to autonomic responses to pain. PMID:26348457

    Joint injury has been recognized as a potent risk factor for the onset of osteoarthritis. The vast majority of studies using imaging technology for longitudinal assessment of patients following joint injury have focused on the injured knee joint, specifically in patients with anterior cruciate ligament injury and meniscus tears where a high risk for rapid onset of post-traumatic osteoarthritis is well known. Although there are many imaging modalities under constant development, magnetic resonance (MR) imaging is the most important instrument for longitudinal monitoring after joint injury. MR imaging is sensitive for detecting early cartilage degeneration and can evaluate other joint structures including the menisci, bone marrow, tendons, and ligaments which can be sources of pain following acute injury. In this review, focusing on imaging following acute knee trauma, several studies were identified with promising short-term results of osseous and soft tissue changes after joint injury. However, studies connecting these promising short-term results to the development of osteoarthritis were limited which is likely due to the long follow-up periods needed to document the radiographic and clinical onset of the disease. Thus, it is recommended that additional high quality longitudinal studies with extended follow-up periods be performed to further investigate the long-term consequences of the early osseous and soft tissue changes identified on MR imaging after acute knee trauma.

    2011-01-01

    Background Whiplash injury affects 83% of persons in a traffic collision and leads to whiplash-associated disorders (WAD). A major challenge facing health care decision makers is identifying cost-effective interventions due to lack of economic evidence. Our objective is to compare the cost-effectiveness of: 1) physician-based education and activation, 2) a rehabilitation program developed by Aviva Canada (a group of property and casualty insurance providers), and 3) the legislated standard of care in the Canadian province of Ontario: the Pre-approved Framework Guideline for Whiplash developed by the Financial Services Commission of Ontario. Methods/Design The economic evaluation will use participant-level data from the University Health Network Whiplash Intervention Trial and will be conducted from the societal perspective over the trial's one-year follow-up. Resource use (costs) will include all health care goods and services, and benefits provided during the trial's 1-year follow-up. The primary health effect will be the quality-adjusted life year. We will identify the most cost-effective intervention using the incremental cost-effectiveness ratio and incremental net-benefit. Confidence ellipses and cost-effectiveness acceptability curves will represent uncertainty around these statistics, respectively. A budget impact analysis will assess the total annual impact of replacing the current legislated standard of care with each of the other interventions. An expected value of perfect information will determine the maximum research expenditure Canadian society should be willing to pay for, and inform priority setting in, research of WAD management. Discussion Results will provide health care decision makers with much needed economic evidence on common interventions for acute whiplash management.

    The aim of the present study was to examine specifically whether the relationship between coping style and symptoms of whiplash injury change as a function of gender. A total of 1709 sufferers of whiplash associated disorder (1349 women, 360 men) belonging to the Danish Society for Polio, Traffic and Accident Victims completed questionnaires measuring demographic and psychological factors (including coping style), and symptoms of whiplash trauma (including pain). Men and women were not found to differ significantly in their use of coping strategies, however emotion focused coping strategies were related significantly more strongly to whiplash related symptoms in men compared to women. Women were found to display more symptoms related to whiplash injury compared to men. Possible reasons for the present findings are discussed in light of related research indicating mood as a potential moderating variable in the relationship between maladaptive coping style and degree of symptoms related to injury in men.

  11. Are MRI high-signal changes of alar and transverse ligaments in acute whiplash injury related to outcome?

    2010-01-01

    Background Upper neck ligament high-signal changes on magnetic resonance imaging (MRI) have been found in patients with whiplash-associated disorders (WAD) but also in non-injured controls. The clinical relevance of such changes is controversial. Their prognostic role has never been evaluated. The purpose of this study was to examine if alar and transverse ligament high-signal changes on MRI immediately following the car accident are related to outcome after 12 months for patients with acute WAD grades 1-2. Methods Within 13 days after a car accident, 114 consecutive acute WAD1-2 patients without prior neck injury or prior neck problems underwent upper neck high-resolution proton-weighted MRI. High-signal changes of the alar and transverse ligaments were graded 0-3. A questionnaire including the impact of event scale for measuring posttraumatic stress response and questions on patients' expectations of recovery provided clinical data at injury. At 12 months follow-up, 111 (97.4%) patients completed the Neck Disability Index (NDI) and an 11-point numeric rating scale (NRS-11) on last week neck pain intensity. Factors potentially related to these outcomes were assessed using multiple logistic regression analyses. Results Among the 111 responders (median age 29.8 years; 63 women), 38 (34.2%) had grades 2-3 alar ligament changes and 25 (22.5%) had grades 2-3 transverse ligament changes at injury. At 12 months follow-up, 49 (44.1%) reported disability (NDI > 8) and 23 (20.7%) neck pain (NRS-11 > 4). Grades 2-3 ligament changes in the acute phase were not related to disability or neck pain at 12 months. More severe posttraumatic stress response increased the odds for disability (odds ratio 1.46 per 10 points on the impact of event scale, p = 0.007) and so did low expectations of recovery (odds ratio 4.66, p = 0.005). Conclusions High-signal changes of the alar and transverse ligaments close after injury did not affect outcome for acute WAD1-2 patients without previous

    Radiological investigations contribute little in differentiating the problems of patients with whiplash injuries. Nevertheless the more prolonged cases of whiplash injuries must not be attributed to preexisting degenerative disease, despite radiologically-proven medicolegal opinion. In this study, 60 patients who were seen for whiplash injuries in the Department for Trauma and Reconstructive Surgery at the University Hospital Hamburg-Eppendorf for clinical and radiological evaluation, an average of 5.7 years post injury, were divided into two groups (n = 30) depending on radiologically-proven preexisting degenerative changes of the cervical spine. On average the patients with degenerative changes were 11.2 years older than those with healthy vertebral columns and also demonstrated an increase in acute symptoms in the lower cervical spine (cervicobrachial syndrome). The chronicity of individual symptoms such as neck-pain, dizziness, nausea and psychological illness was also observed in both groups. Problems such as paresthesias as well as pain in the shoulder-arm-area appeared to increase in subsequent check-ups, irrespective of the earlier degenerative changes. Patients with typical posterior headaches recovered faster when they had radiologically normal spines. Presenting late, there was a significant accumulation of patients with pre-existing degenerative changes complaining merely of tinnitus. The earlier changes in any individual motion segment do not determine the clinical course of whiplash injuries, but merely represent an area of increased vulnerability to trauma. On the other hand, trauma has not been proven to influence the development or aggravation of degenerative changes in normal or diseased spines. We are not able to differentiate the posttraumatic course from the natural history of the degenerative process, either clinically or radiologically. Considering the involvement of sensitive neurological structures the classical objective organic diagnosis

    Abstract Hyperthermia may accentuate the detrimental consequences of brain injury and worsen the outcome of patients with acute head trauma, especially severe traumatic brain injury (TBI). We explored the effect of different magnitudes and durations of hyperthermia in the first 3 days after injury on the outcome of 7145 patients with acute head trauma, including 1626 with severe TBI. The differences in mortality and unfavorable outcome between the normothermia group, mild fever group, moderate fever group, and high fever group were statistically significant (p<0.001). The mortality and unfavorable outcome of severe TBI patients in the groups also differed significantly (p<0.001). The mortality and unfavorable outcome of patients with 1 day, 2 days, and 3 days of high fever were significantly increased (p<0.01). Our data strongly indicate that both degree and duration of early post-trauma hyperthermia are closely correlated with the outcome of acute TBI patients, especially severely injured ones, which indicates that hyperthermia may play a detrimental role in the delayed mechanisms of damage after acute TBI. Prevention of early hyperthermia after acute head trauma is therefore essential to the management of TBI patients. PMID:22026424

    Many trauma patients are acutely intoxicated with alcohol. Animal studies have demonstrated that acute alcohol intoxication inhibits the normal release of epinephrine, norepinephrine, and vasopressin in response to acute hemorrhage. Ethanol also increases nitric oxide release and inhibits antidiuretic hormone secretion. This article studies the effects of alcohol intoxication (measured by blood alcohol level, BAL) on the presentation and resuscitation of trauma patients with blunt hepatic injuries. A retrospective registry and chart review was conducted of all patients who presented with blunt liver injuries at an ACS-verified, level I trauma center. Data collected included admission BAL, systolic blood pressure, hematocrit, International Normalized Ratio (INR), liver injury grade, Injury Severity Score (ISS), intravenous fluid and blood product requirements, base deficit, and mortality. From September 2002 to May 2008, 723 patients were admitted with blunt hepatic injuries. Admission BAL was obtained in 569 patients, with 149 having levels >0.08%. Intoxicated patients were more likely to be hypotensive on admission (p = 0.01) despite a lower liver injury grade and no significant difference in ISS. There was no significant difference in the percent of intoxicated patients requiring blood transfusion. However, when blood was given, intoxicated patients required significantly more units of packed red blood cells (PRBC) than their nonintoxicated counterparts (p = 0.01). Intoxicated patients also required more intravenous fluid during their resuscitation (p = 0.002). Alcohol intoxication may impair the ability of blunt trauma patients to compensate for acute blood loss, making them more likely to be hypotensive on admission and increasing their PRBC and intravenous fluid requirements. All trauma patients should have BAL drawn upon admission and their resuscitation should be performed with an understanding of the physiologic alterations associated with acute alcohol

    Introduction Whiplash-associated disorder (WAD) causes substantial social and economic burden internationally. Up to 60% of patients with WAD progress to chronicity. Research therefore needs to focus on effective management in the acute stage to prevent the development of chronicity. Approximately 93% of patients are classified as WADII (neck complaint and musculoskeletal sign(s)), and in the UK, most are managed in the private sector. In our recent systematic review, a combination of active and behavioural physiotherapy was identified as potentially effective in the acute stage. An Active Behavioural Physiotherapy Intervention (ABPI) was developed through combining empirical (modified Delphi study) and theoretical (social cognitive theory focusing on self-efficacy) evidence. This pilot and feasibility trial has been designed to inform the design of an adequately powered definitive randomised controlled trial. Methods and analysis Two parallel phases. (1) An external pilot and feasibility cluster randomised double-blind (assessor and participants), parallel two-arm (ABPI vs standard physiotherapy) clinical trial to evaluate procedures and feasibility. Six UK private physiotherapy clinics will be recruited and cluster randomised by a computer-generated randomisation sequence. Sixty participants (30 each arm) will be assessed at recruitment (baseline) and at 3 months postbaseline. The planned primary outcome measure is the neck disability index. (2) An embedded exploratory qualitative study using semistructured indepth interviews (n=3–4 physiotherapists) and a focus group (n=6–8 patients) and entailing the recruitment of purposive samples will explore perceptions of the ABPI. Quantitative data will be analysed descriptively. Qualitative data will be coded and analysed deductively (identify themes) and inductively (identify additional themes).

    2008-02-01

    A whiplash event is a relative motion between the head and torso that occurs in rear-end automobile collisions. In particular, the large inertia of the head results in a horizontal translation relative to the thorax. This paper describes a simulation of the motion of the head and neck during a rear-end (whiplash) collision. A head-neck model that qualitatively undergoes the same forces acting in whiplash and shows the same behavior is used to analyze the kinematics of both the head and the cervical spine and the resulting neck loads. The rapid acceleration during a whiplash event causes the extension and flexion of the cervical spine, which in turn can cause dislocated vertebrae, torn ligaments, intervertebral disc herniation, and other trauma that appear to be the likely causes of subsequent painful headache or neck pain symptoms. Thus, whiplash provides a connection between the dynamics of the human body and physics. Its treatment can enliven the usual teaching in kinematics, and both theoretical and experimental approaches provide an interesting biological context to teach introductory principles of mechanics.

    Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13%) following blunt injury and 20 (87%) after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury. PMID:23723618

    The aim of this paper was to review the physical and psychological processes associated with whiplash-associated disorders. There is now much scientific data available to indicate the presence of disturbed nociceptive processing, stress system responses, muscle and motor changes as well as psychological factors in both acute and chronic whiplash-associated disorders. Some of these factors seem to be associated with the transition from acute to chronic pain and have demonstrated prognostic capacity. Further investigation is required to determine if these processes can be modified and if modification will lead to improved outcomes for this condition. The burden of whiplash injuries, the high rate of transition to chronicity, and evidence of limited effects of current management on transition rates demand new directions in evaluation and management. The understanding of processes underlying this condition is improving and this lays the foundation for the development of more effective management approaches. PMID:23115472

    1997-09-01

    Previous studies have shown that some persons with longlasting problems after whiplash have changed eye movements. These changes have been related to disturbance of the posture control system. The question raised in the present study is whether such disturbances can influence daily life functions connected with balance, position and external movements, such as car driving. A group of 23 persons with disturbed eye movements due to whiplash injury, was tested in a driving simulator, together with a closely matched control group. The results revealed significant differences between the two groups with respect to response times to the traffic signs presented, identification of type of sign, as well as steering precision while the subjects' attention was directed to the process of identifying the signs. Alternative explanations such as driving experience, pain, medication or malingering are at least partly controlled for, but cannot completely be ruled out. A distorted posture control system leading to disturbance of eye movements seems to be the most likely primary causative factor, but these disturbances are most certainly complexly determined. Reduced attention capacity is considered to be a mediating secondary factor. Registration of eye movements may be a useful diagnostic tool to evaluate driving skill after whiplash. PMID:9309948

Two independent reviewers searched information sources, decided eligibility of studies, and assessed risk of bias (RoB) of included trials. Data were extracted by one reviewer and checked by the other. A third reviewer mediated any disagreements throughout. Qualitative trial and RoB data were summarised descriptively. Quantitative syntheses were conducted across trials for comparable interventions, outcome measures and assessment points. Meta-analyses compared effect sizes with random effects, using STATA version 12. Data Sources PEDro, Medline, Embase, AMED, CINAHL, PsycINFO, and Cochrane Library with manual searching in key journals, reference lists, British National Bibliography for Report Literature, Center for International Rehabilitation Research Information & Exchange, and National Technical Information Service were searched from inception to 15th April 2015. Active researchers in the field were contacted to determine relevant studies. Eligibility Criteria for Selecting Studies RCTs evaluating acute (<4 weeks) WADII, any conservative intervention, with outcome measures important to the International Classification of Function, Disability and Health. Results Fifteen RCTs all assessed as high RoB (n=1676 participants) across 9 countries were included. Meta-analyses enabled 4 intervention comparisons: conservative versus standard/control, active versus passive, behavioural versus standard/control, and early versus late. Conservative intervention was more effective for pain reduction at 6 months (95%CI: -20.14 to -3.38) and 1-3 years (-25.44 to -3.19), and improvement in cervical mobility in the horizontal plane at <3 months (0.43 to 5.60) compared with standard/control intervention. Active intervention was effective

    Objective: To review the literature on whiplash injury including an overview, collision mechanics, pathophysiology, neurobehavioral, imaging, treatment/management, prognosis, outcomes, and litigation. Design: An annotated bibliography. Methods: A literature search of MEDLINE from 1987 to 1995 and CHIROLARS from 1900 to 1996, with emphasis on the last ten years, was performed. Conference proceedings and the personal files of the authors were searched for relevant citations. Key words utilized in the search were whiplash injury, acceleration/deceleration injury, neck pain, head pain, cognitive impairment, treatment, imaging, prognosis and litigation. Results: This annotated bibliography identifies key studies and potential models for future research. Conclusions: There is currently a lack of clinical consensus both in practice and in the literature regarding the evaluation and management of an episode of whiplash injury. This annotated bibliography has been developed in an attempt to provide an overview of the literature regarding various issues surrounding an episode of whiplash injury.

    The greatest advantages of laparoscopy when compared to open surgery include the faster recovery times, shorter hospital stays, decreased postoperative pain, earlier return to work and resumption of normal daily activity as well as cosmetic benefits. Laparoscopy today is considered the gold standard of care in the treatment of cholecystitis and appendicitis worldwide. Laparoscopy has even been adopted in colorectal surgery with good results. The technological improvements in this surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its utilization in operations with fully intracorporeal anastomoses. Further progress in laparoscopy has included single-incision laparoscopic surgery and natural orifice trans-luminal endoscopic surgery. Nevertheless, laparoscopy for emergency surgery is still considered challenging and is usually not recommended due to the lack of adequate experience in this area. The technical difficulties of operating in the presence of diffuse peritonitis or large purulent collections and diffuse adhesions are also given as reasons. However, the potential advantages of laparoscopy, both in terms of diagnosis and therapy, are clear. Major advantages may be observed in cases with diffuse peritonitis secondary to perforated peptic ulcers, for example, where laparoscopy allows the confirmation of the diagnosis, the identification of the position of the ulcer and a laparoscopic repair with effective peritoneal washout. Laparoscopy has also revolutionized the approach to complicated diverticulitis even when intestinal perforation is present. Many other emergency conditions can be effectively managed laparoscopically, including trauma in select hemodynamically-stable patients.

    An Acute Trauma Care (ATC) course was adapted for resource-limited healthcare systems based on the American model of initial care for injured patients. The course was taught to interested medical personnel in Kenya. This study undertook a survey of the participants' healthcare facilities to maximize the applicability of ATC across healthcare settings. The ATC course was conducted three times in Kenya in 2006. A World Health Organization (WHO) Needs Assessment survey was administered to 128 participants. The data were analyzed qualitatively and quantitatively. Ninety-two per cent had a physician available in the emergency department and 63 per cent had a clinical officer. A total of 71.7 per cent reported having a designated trauma room. A total of 96.7 per cent reported running water, but access was uninterrupted more often in private hospitals as opposed to public facilities (92.5 vs 63.6%, P = 0.0005). Private and public employees equally had an oxygen cylinder (95.6 vs 98.5%, P > 0.05), oxygen concentrator (69.2 vs 54.2%, P = 0.12), and oxygen administration equipment (95.7 vs 91.4%, P > 0.05) at their facilities. However, private employees were more likely to report that "all" of their equipment was in working order (53 vs 7.9%, P < 0.0001). Private employees were also more likely to report that they had access to information on emergency procedures and equipment (64.4 vs 33.3%, P = 0.001) and that they had learned new procedures (54.8 vs 25.4%, P = 0.002). Despite a perception of public facility lack, this survey showed that public institutions and private institutions have similar basic equipment availability. Yet, problems with equipment malfunction, lack of repair, and availability of required information and training are far greater in the public sector. The content of the ATC course is valid for both private and public sector institutions, but refinements of the course should focus on varying facets of inexpensive and alternative equipment resources

    This ACR Appropriateness Criteria article offers imaging triage guidance for several variants of patients presenting with acute foot trauma. Patients meeting inclusion criteria for the Ottawa Rules should undergo a 3-view radiographic series. Diabetic patients with peripheral neuropathy should undergo radiography, even though they do not meet the Ottawa Rules inclusion criteria. Patients with suspected midfoot and/or Lisfranc injury should undergo 3-view radiographs with weight bearing on at least the anterior-posterior view. Patients with suspected Lisfranc injury and normal radiographs should be considered for MRI and CT on a case-by-case basis. MRI or ultrasound could confirm cases of suspected acute tendon rupture. Radiography is the initial imaging modality for suspected plantar plate injury after metatarsal-phalangeal joint injury. Weight-bearing anterior-posterior, lateral, and sesamoid axial views may detect proximal migration of the hallux sesamoids. Ultrasound or MRI can directly evaluate the capsuloligamentous complex, specifically the plantar plate. Radiography can detect radiopaque penetrating foreign bodies, and ultrasound can be helpful in detecting those that are nonradiopaque. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 3 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 instances in which evidence is lacking or is not definitive, expert opinion may be used to recommend imaging and treatment. PMID:25935824

    Chronic whiplash-associated disorder (WAD) is common after whiplash injury, with considerable personal, social, and economic burden. Despite decades of research, factors responsible for continuing pain and disability are largely unknown, and diagnostic tools are lacking. Here, we report a novel model of mechanical ventral neck muscle function recorded from non-invasive, real-time, ultrasound measurements. We calculated the deformation area and deformation rate in 23 individuals with persistent WAD and compared them to 23 sex- and age-matched controls. Multivariate statistics were used to analyse interactions between ventral neck muscles, revealing different interplay between muscles in individuals with WAD and healthy controls. Although the cause and effect relation cannot be established from this data, for the first time, we reveal a novel method capable of detecting different neck muscle interplay in people with WAD. This non-invasive method stands to make a major breakthrough in the assessment and diagnosis of people following a whiplash trauma. PMID:26472599

    Objective: The aim of this study was to determine the application value of a trauma index (TI) to assess condition and likelihood of death in hospitalized patients with acute trauma (AT). Methods: Trauma index scores and injury severity scores (ISS) were assessed in 1,802 randomly selected cases of AT-hospitalized patients. The receiver operating characteristic (ROC) curve was used to compare the clinical values of TI and ISS values to predict outcomes in AT-hospitalized patients. Results: The area under the ROC curve for TI scores was 0.896 (95% CI [0.881, 0.909]), while for ISS, it was 0.792 (95% CI [0.773, 0.811]). This difference was not statistically significant (z = 3.236, P = 0.001). Potentially critical disease conditions in AT-hospitalized patients were best identified when TI scores were ≥ 16 points and ISS values were ≥ 22 points. Conclusions: Trauma Index scores exhibited a higher resolution for outcome prediction in AT-hospitalized patients compared to ISS values. The implementation of this scale was simple, reliable, easy to learn, and could quickly identify disease, which is vital for early detection and treatment of critical trauma patients. PMID:26770541

    Obesity is associated with an increased risk of acute kidney injury (AKI) after blunt traumatic injury in humans. Because limitations exist in studying trauma in human patients, animal models are necessary to elucidate mechanisms of remote organ injury after trauma. We developed a model of severe orthopedic trauma in lean (LZ) and obese (OZ) Zucker rats, in which OZ develop greater kidney dysfunction after trauma than LZ. Orthopedic trauma was inflicted via bilateral hindlimb soft tissue injury, fibula fracture, and injection of homogenized bone components. Mean arterial pressure (MAP) and heart rate (HR) were measured for 6 h after trauma, and again at 24 h after trauma. Urine was collected for 24 h before and after trauma to measure urine albumin excretion. Glomerular filtration rate (GFR), renal plasma flow (RPF), plasma interleukin-6 (IL-6), and renal macrophage infiltration (ED-1 [CD68 Antibody] immunostaining) were measured in animals with and without trauma. MAP and HR were similar between LZ and OZ throughout the study, with the exception that OZ had a 18 mmHg lower pressure 24 h posttrauma. GFR and RPF were decreased significantly (∼50%), while urine albumin excretion, plasma IL-6, and renal ED-1-positive cells were increased in OZ 24 h after trauma compared to both OZ without trauma and LZ after trauma. In conclusion, these data are consistent with studies in humans that show that AKI develops more frequently in obese than in lean individuals. This model will be an important experimental tool to better understand the underlying mechanisms of poor outcomes after trauma in obese patients. PMID:24303169

    Whiplash is a lay term combining all the complications of a cervical sprain or distortion associated with an extension. It may lead to cervical or back pain, but patients may also complain about functional visual impairment. These visual complaints: fixation disparity, heterophoria or convergence insufficiency, are frequently neglected and difficult to quantitate and treat. Establishing the relationship between the indirect cervical trauma and the visual signs may be challenging for the medical-legal expert and must include consideration of the previous oculomotor status of the patient.

    INTRODUCTION Acute appendicitis commonly presents as an acute abdomen. Cases of acute appendicitis caused by blunt abdominal trauma are rare. We present a systematic review of appendicitis following blunt abdominal trauma. The aim of this review was to collate and report the clinical presentations and experience of such cases. SUBJECTS AND METHODS A literature review was performed using PubMed, Embase and Medline and the keywords ‘appendicitis’, ‘abdominal’ and ‘trauma’. RESULTS The initial search returned 381 papers, of which 17 articles were included. We found 28 cases of acute appendicitis secondary to blunt abdominal trauma reported in the literature between 1991 and 2009. Mechanisms of injury included road-traffic accidents, falls, assaults and accidents. Presenting symptoms invariably included abdominal pain, but also nausea, vomiting and anorexia. Only 12 patients had computed tomography scans and 10 patients had ultrasonography. All reported treatment was surgical and positive for appendicitis. CONCLUSIONS Although rare, the diagnosis of acute appendicitis must be considered following direct abdominal trauma especially if the patient complains of abdominal right lower quadrant pain, nausea and anorexia. Haemodynamically stable patients who present shortly after blunt abdominal trauma with right lower quadrant pain and tenderness should undergo urgent imaging with a plan to proceed to appendicectomy if the imaging suggested an inflammatory process within the right iliac fossa.

    The aim of the present work was to assess the influences of age, gender, and the severity of brain trauma on recovery of motor function using kinetotherapy. The study included 131 patients (99 men and 32 women) investigated during the acute phase of trauma in the Department of Brain Trauma, Clinical Hospital, Kaunas Medical University. After stabilization, 80 patients were transferred to the neurorehabilitation clinic and 51 were transferred to other rehabilitation centers. Motor function in the patients was assessed using the Clinical Outcomes Variable Scale (COVS) at the beginning and end of the acute trauma period and during early rehabilitation, i.e., at the beginning, 25 days later, and on completion. During the acute trauma period, patients had impairments to the abilities to turn over, sit, maintain balance while sitting, to move horizontally and vertically, walk, and use mobility aids, along with reductions in walking duration and speed, and difficulty in wheelchair mobility and hand functions. Kinetotherapy yielded high or intermediate levels of efficacy in 90% of the patients. The efficacy of kinetotherapy was significantly greater in young patients than in elderly and old patients (p < 0.05). Gender and trauma severity had no statistically significant effects on the efficacy of kinetotherapy (p > 0.05). PMID:18802769

  15. Acute acoustic trauma: dynamics of hearing loss following cessation of exposure.

    The natural history of individuals with acute acoustic trauma who ceased to be exposed to impact noise was examined. Retrospective follow-up was carried out for 4 years on patients who were qualified as disabled following acoustic trauma with permanent threshold shift. Eight hundred forty-one individuals (1682 ears) were examined, of which 1514 ears with acoustic trauma were included in the study group; 150 individuals (300 ears) who continued to be exposed to impact noise even after discovery of acoustic trauma comprised the control group. In the latter, as long as exposure to gunfire continued, the severity of acoustic trauma increased. In the study group, during the first year after injury, changes were observed in hearing, whether improvement or deterioration; after this period, hearing loss appeared to be final. We suggest that, after 1 year following acute acoustic trauma, the associated hearing loss be considered as final, provided there is no further exposure to noise. This finding holds great importance from the medicolegal standpoint, an aspect that is unclear in the literature. It clarifies that beyond the period of 1 year after initial exposure, the pathologic process ceases (as long as there is no additional exposure to noise or gunfire). Further hearing deterioration beyond this period is not related to the initial acoustic trauma but rather to other factors. PMID:3177612

    The "stinger" or "burner" is a form of transient brachial plexopathy termed for its characteristic knife-like pain extending from the neck to the fingertips. Muscle weakness and paresthesia are oftentimes associated symptoms and are similarly temporary. Commonly observed in athletes of contact sports, the stinger results from high force trauma causing either traction/direct compression to the brachial plexus or extension/compression of the cervical nerve roots. We describe a pediatric case of a stinger in a 14-year-old boy, which was caused by a relatively low force trauma accident. Our management strategy and recommendations are discussed. PMID:26893985

    Background Exposure to acute, potentially traumatic events is an unfortunately common experience for children and adolescents. Posttraumatic stress (PTS) responses following acute trauma can have an ongoing impact on child development and well-being. Early intervention to prevent or reduce PTS responses holds promise but requires careful development and empirical evaluation. Objectives The aims of this review paper are to present a framework for thinking about the design, delivery, and evaluation of early interventions for children who have been exposed to acute trauma; highlight targets for early intervention; and describe next steps for research and practice. Results and conclusions Proposed early intervention methods must (1) have a firm theoretical grounding that guides the design of intervention components; (2) be practical for delivery in peri-trauma or early post-trauma contexts, which may require creative models that go outside of traditional means of providing services to children; and (3) be ready for evaluation of both outcomes and mechanisms of action. This paper describes three potential targets for early intervention—maladaptive trauma-related appraisals, excessive early avoidance, and social/interpersonal processes—for which there is theory and evidence suggesting an etiological role in the development or persistence of PTS symptoms in children.

    Although acute brain trauma often results from head damage in different accidents and affects a substantial fraction of the population, there is no effective treatment for it yet. Limitations of currently used animal models impede understanding of the pathology mechanism. Multiphoton microscopy allows studying cells and tissues within intact animal brains longitudinally under physiological and pathological conditions. Here, we describe two models of acute brain injury studied by means of two-photon imaging of brain cell behavior under posttraumatic conditions. A selected brain region is injured with a sharp needle to produce a trauma of a controlled width and depth in the brain parenchyma. Our method uses stereotaxic prick with a syringe needle, which can be combined with simultaneous drug application. We propose that this method can be used as an advanced tool to study cellular mechanisms of pathophysiological consequences of acute trauma in mammalian brain in vivo. In this video, we combine acute brain injury with two preparations: cranial window and skull thinning. We also discuss advantages and limitations of both preparations for multisession imaging of brain regeneration after trauma. PMID:24748024

    The role of repeated exposure to collective trauma in explaining response to subsequent community-wide trauma is poorly understood. We examined the relationship between acute stress response to the 2013 Boston Marathon bombings and prior direct and indirect media-based exposure to three collective traumatic events: the September 11, 2001 (9/11) terrorist attacks, Superstorm Sandy, and the Sandy Hook Elementary School shooting. Representative samples of residents of metropolitan Boston (n = 846) and New York City (n = 941) completed Internet-based surveys shortly after the Boston Marathon bombings. Cumulative direct exposure and indirect exposure to prior community trauma and acute stress symptoms were assessed. Acute stress levels did not differ between Boston and New York metropolitan residents. Cumulative direct and indirect, live-media-based exposure to 9/11, Superstorm Sandy, and the Sandy Hook shooting were positively associated with acute stress responses in the covariate-adjusted model. People who experience multiple community-based traumas may be sensitized to the negative impact of subsequent events, especially in communities previously exposed to similar disasters. PMID:25896419

    Blunt chest traumatic coronary artery dissection is an uncommon cause of atherosclerotic and non-atherosclerotic Acute Myocardial Infarction (AMI). Injuries of the coronary artery after blunt chest trauma are caused by different mechanisms such as vascular spasm, dissection and intimal tear or rupture of an existing thrombus formation. Chest pain might be masked by other injuries in patients with multiple traumas in car accident. Present case report is on a 37-year-old male without any specific past medical history who reported to the emergency department of a hospital with chest discomfort and was discharged with the impression of chest wall pain. After three days he experienced severe chest pain and he was admitted with the impression of acute coronary syndrome and underwent coronary angiography which showed Left Anterior Descending (LAD) artery dissection. The possibility of injury of the coronary artery should be kept in mind after blunt trauma to the chest. This condition is sometimes underdiagnosed. Its diagnosis may be difficult because chest pain can be interpreted as being secondary to chest wall contusion or it may be overshadowed by other injuries. Coronary dissection diagnosis after chest trauma requires clinical suspicion and systematic evaluation. Electrocardiography (ECG) should be done for every patient with thoracic trauma as the clinical findings may be misleading. PMID:27504338

    Acute compartment syndrome is a serious emergency that warrants urgent decompression, and tennis leg (i.e., rupture of the medial head of the gastrocnemius) is a known clinical condition that is usually treated symptomatically, with good results overall. In rare cases, acute compartment syndrome is associated with tennis leg after severe direct muscle trauma or severe exercise in athletes or physically active individuals. We present an unusual case of acute compartment syndrome secondary to tennis leg after the patient, a nonathlete, had disembarked from a truck without any trauma. Clinicians should have a high index of suspicion for atraumatic compartment syndrome, and timely surgical fasciotomy must be undertaken to avoid complications resulting from delayed diagnosis and treatment.

    The number of cases with child abuse is increasing in Japan, and abusive head trauma (AHT) is a major cause of death in abused children. Child abuse has been recognized by the late 19th century, and widely accepted as battered child syndrome in the middle of the 20th century. As terms, there had been considerable mechanistic controversies between shaken-baby and -impact syndrome until the beginning of the 21st century. In recent years, AHT has been utilized as a less mechanistic term.

    The number of cases with child abuse is increasing in Japan, and abusive head trauma (AHT) is a major cause of death in abused children. Child abuse has been recognized by the late 19th century, and widely accepted as battered child syndrome in the middle of the 20th century. As terms, there had been considerable mechanistic controversies between shaken-baby and -impact syndrome until the beginning of the 21st century. In recent years, AHT has been utilized as a less mechanistic term. Most of the characteristics of AHT in Japan have been similar to those in the United States as follows: infant is the most common victim, acute subdural hematoma (SDH) is the most common intracranial lesion, and retinal hemorrhage is often complicated. On the other hand, several characteristics have been different as follows: mother is the most common perpetrators, impact is a more common mechanism of trauma than shaking, and external trauma is more common reflecting the existence of impact.

    Background To determine the prevalence of platelet dysfunction, using an end-point of assembly into a stable thrombus, following severe injury. Background: Although the current debate on acute traumatic coagulopathy (ATC) has focused on the consumption or inhibition of coagulation factors, the question of early platelet dysfunction in this setting remains unclear. Study Design Prospective platelet function in assembly and stability of the thrombus was determined within 30 minutes of injury using whole blood samples from trauma patients at the point of care employing thrombelastography (TEG)-based platelet functional analysis. Results There were 51 patients in the study. There were significant differences in the platelet response between trauma patients and healthy volunteers such that there was impaired aggregation to these agonists. In trauma patients, the median ADP inhibition of platelet function was 86.1% (IQR: 38.6–97.7%), compared to 4.2 % (IQR 0–18.2%) in healthy volunteers. Following trauma, the impairment of platelet function in response to AA was 44.9% (IQR 26.6–59.3%), compared to 0.5% (IQR 0–3.02%) in volunteers (Wilcoxon non parametric test p<0.0001 for both tests). Conclusions In this study, we show that platelet dysfunction is manifest following major trauma, before significant fluid or blood administration. These data suggest a potential role for early platelet transfusion in severely injured patients at risk for postinjury coagulopathy. PMID:22520693

    Background Mitochondrial proteins and genes are damaged after burn injury in animals but have not previously been assessed in human burn patients. Methods The rates of maximal muscle mitochondrial oxidative capacity(ATP production) and uncoupled oxidation(heat production) for both palmitate and pyruvate were measured in muscle biopsies from 40 children sustaining burns >40% body surface area and from 13 healthy children controls. Results Maximal mitochondrial oxidation of pyruvate and palmitate were reduced in burn patients compared to controls (4.0±0.2:1.9±0.1 µmolO2/citrate synthase activity/mg protein/min pyruvate; Control:Burn;P<0.001 and 3.0±0.1:0.9±0.03 µmolO2/citrate synthase activity/mg protein/min palmatyl CoA; Control:Burn;P=0.003). Uncoupled oxidation was the same between groups. Conclusions The maximal coupled mitochondrial oxidative capacity is severely impaired after burn injury, although there are no alterations in the rate of uncoupled oxidative capacity. It may be that the ratio of these indicates that a larger portion of energy production in trauma patients is wasted through uncoupling, rather than used for healing. PMID:18639661

    Blunt thoracic trauma is a common occurrence in automobile accidents. Acute myocardial infarction (AMI) caused by coronary dissection following blunt thoracic trauma is rare. We report a case of healthy 24-year-old man with a history of blunt thoracic injury with subsequent undetected AMI who died of acute decompensated heart failure 4 days after the insult. The autopsy findings showed a 90% luminal narrowing of the left anterior descending coronary artery by dissecting hematoma, 3 cm in length. The myocardium revealed transmural myocardial infarction affecting apex, most part of left ventricular free wall, and interventricular septum. Both lungs were heavy, wet, and noncrepitant. Histological findings of the infarcted myocardium were consistent with 3-5 days post-AMI. Sections from both lungs revealed massive pulmonary edema, reflecting acute decompensated heart failure following a large AMI secondary to coronary dissection. Blunt thoracic trauma may obscure typical chest pain associated with cardiac ischemia especially in cases with a high tolerance for pain. PMID:26454807

    Background: Efficient pain management is one of the most important components of care in the field of emergency medicine. Objectives: This study was conducted to compare intravenous paracetamol and intravenous morphine sulfate for acute pain reduction in patients with limb trauma. Patients and Methods: In a randomized double-blinded clinical trial, all patients (aged 18 years and older) with acute limb trauma and a pain score of greater than 3/10 in the emergency department were recruited; they received either 1 g intravenous paracetamol or 0.1 mg/kg intravenous morphine sulfate over 15 minutes. The primary outcome was the pain score measured on a numerical rating scale at 0, 15 and 30 minutes after commencing drug administration. The requirement for rescue analgesia and the frequency of adverse reactions were also recorded. Results: Sixty patients randomly received either IV paracetamol (n = 30) or IV morphine (n = 30). The mean reduction in numerical rating scale pain intensity scores at 30 minutes was 3.86 (± 1.61) for paracetamol, and 2.16 (± 1.39) for morphine. However, pain relief was significantly higher in the paracetamol group compared to the morphine group (P < 0.001). Four patients in the paracetamol group and 15 patients in the morphine group needed rescue analgesia and the difference was significant (P = 0.05). Conclusions: Intravenous paracetamol appears to provide better analgesia than intravenous morphine in acute limb trauma. Further larger studies are required. PMID:27218042

    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.

    More than 50% of severely injured patients have chest trauma. Second insults frequently result in acute lung injury (ALI), with sepsis being the main underlying condition. We aimed to develop a standardized, reproducible, and clinically relevant double-hit mouse model of ALI induced by chest trauma and polymicrobial sepsis and to investigate the pathophysiologic role of activated neutrophils. Lung contusion was applied to C57Bl/6 mice via a focused blast wave. Twenty-four hours later, sepsis was induced by cecal ligation and puncture. For polymorphonuclear leukocyte (PMN) depletion, animals received intravenous injections of PMN-depleting antibody. In response to blunt chest trauma followed by sepsis as well as after sepsis alone, a significant local and systemic inflammatory response with increased cytokine/chemokine levels in lung and plasma was observed. In contrast, lung apoptosis was markedly elevated only after a double hit. Intra-alveolar neutrophils and total bronchoalveolar lavage protein concentrations were markedly increased following isolated chest trauma or the combined insult, but not after sepsis alone. Lung myeloperoxidase activity was enhanced only in response to the double hit accompanied by histological disruption of the alveolar architecture, lung congestion, and marked cellular infiltrates. Neutrophil depletion significantly diminished lung interleukin 1β and interleukin 6 concentrations and reduced the degree of septic ALI. Here we have established a novel and highly reproducible mouse model of chest trauma-induced septic ALI characterizing a clinical relevant double-hit scenario. In particular, the depletion of neutrophils substantially mitigated the extent of lung injury, indicating a pathomechanistic role for neutrophils in chest trauma-induced septic ALI. PMID:22552016

    Acute traumatic temporomandibular joint disc displacement (ATDD) and its sequelae are not familiar for most surgeons. This study is to discuss its sequelae in cases without disc reduction after failed conservative treatment. From 2010 to 2015, 26 patients with 34 joints were included in the study. All patients had at least 3 months conservative treatment. Their maximal incisor opening (MIO) was measured during follow-ups and MRI examination was used to check the condylar bone degeneration. The mean follow-up for conservative treatment after admission was 8.69 months, the patients reached an average of 25.7 mm MIO. MRI showed condylar bone intact in 8 joints (23.5%), condylar surface bone destruction (Wilks IV, V stages) in 14 joints (41.2%), and severe bone resorption in 12 joints (35.3%). 15 patients with 23 joints were asked for surgical treatment after a mean conservative treatment of 5.4 months (3-12 months) to improve mouth opening and relieve chronic pain. 12 joints had total joint replacement (TJR). 11 joints had disc repositioning. Their mean MIO before operation was 19.8 mm and significantly improved to 33.9 mm after operation (p = 0.0000). ATDD may cause severe osteoarthritis or ankylosis. Disc repositioning and TJR could significantly improve MIO. PMID:27582054

  15. Acute refractory hypoxemia after chest trauma reversed by high-frequency oscillatory ventilation: a case report

    PubMed Central

    2013-01-01

    Introduction Polytrauma often results in significant hypoxemia secondary to direct lung contusion or indirectly through atelectasis, systemic inflammatory response, large volume fluid resuscitation and blood product transfusion. In addition to causing hypoxemia, atelectasis and acute lung injury can lead to right ventricular failure through an acute increase in pulmonary vascular resistance. Mechanical ventilation is often applied, accompanied with recruitment maneuvers and positive end-expiratory pressure in order to recruit alveoli and reverse atelectasis, while preventing excessive alveolar damage. This strategy should lead to the reversal of the hypoxemic condition and the detrimental heart–lung interaction that may occur. However, as described in this case report, hemodynamic instability and intractable alveolar atelectasis sometimes do not respond to conventional ventilation strategies. Case presentation We describe the case of a 21-year-old Caucasian man with severe chest trauma requiring surgical interventions, who developed refractory hypoxemia and overt right ventricular failure. After multiple failed attempts of recruitment using conventional ventilation, the patient was ventilated with high-frequency oscillatory ventilation. This mode of ventilation allowed the reversal of the hemodynamic effects of severe hypoxemia and of the acute cor pulmonale. We use this case report to describe the physiological advantages of high-frequency oscillatory ventilation in patients with chest trauma, and formulate the arguments to explain the positive effect observed in our patient. Conclusions High-frequency oscillatory ventilation can be used in the context of a blunt chest trauma accompanied by severe hypoxemia due to atelectasis. The positive effect is due to its capacity to recruit the collapsed alveoli and, as a result, the relief of increased pulmonary vascular resistance and subsequently the reversal of acute cor pulmonale. This approach may represent an

    Millions of children worldwide experience acute medical events. Children’s responses to these events range from transient distress to significant posttraumatic stress disorder symptoms (PTSS). While many models suggest explanations for the development and maintenance of PTSS in adults, very few have focused on children. Current models of child PTSS are primarily restricted to the post-trauma period, thus neglecting the critical peri-trauma period when screening and preventive interventions may be most easily implemented. Research on PTSS in response to pediatric medical trauma typically examines predictors in isolation, often overlooking potentially important interactions. This paper proposes a new model utilizing the bio-psycho-social framework and focusing on peri-trauma processes of acute medical events. Understanding the relationships among bio-psycho-social factors during peri-trauma can inform early identification of at-risk children, preventive interventions, and clinical care. Recommendations for future research, including the need to examine PTSS in the context of multiple influences, are discussed. PMID:25217001

    BACKGROUND: Acute orthopedic trauma contributes substantially to the global burden of disease. OBJECTIVES: The present systematic review aimed to summarize the current knowledge concerning prognostic factors for the presence of persistent pain, pain severity and pain-related disability following acute orthopedic trauma involving a spectrum of pathologies to working-age adults. METHODS: The Ovid MEDLINE and EMBASE databases were searched for level II prognostic studies published between January 1996 and October 2010. Studies that were longitudinal and reported results with multivariate analyses appropriate for prognostic studies were included. Studies that addressed two specific injury types that have been the subject of previous reviews, namely, injuries to the spinal column and amputations, were excluded. RESULTS: The searches yielded 992 studies; 10 studies met the inclusion criteria and were rated for methodological quality. Seventeen factors were considered in more than one cohort. There was strong evidence supporting the association of female sex, older age, high pain intensity, preinjury anxiety or depression, and fewer years of education with persistent pain outcomes. There was moderate evidence supporting the association between postinjury depression or anxiety with persistent pain, and that injury severity was not a risk factor for ongoing pain. CONCLUSION: Many individuals experience persistent pain following acute trauma. Due to the lack of studies, the use of different constructs to measure the same factor and the methodological limitations associated with many of the studies, the present review was only able to reliably identify a limited set of factors that predicted persistent pain. Recommendations for the conduct of future methodologically rigorous studies of persistent pain are provided. PMID:22518366

    Acute cervical sprain traumas can be divided into simple and severe, depending on the presence of organic lesions which can be documented by conventional radiologic techniques. Persistent painful symptomatology of the nape and the precise localization of pain, led us to suspect the presence of organic lesions due to tearing of the neck muscles in 94 patients who had suffered a simple cervical sprain. To demonstrate these post-traumatic lesions, the patients were subjected to US examinations of both the nape and the muscles at the base of the neck. In 13 cases (13.8%) muscular tearing lesions were demonstrated, which were characterized by hypoechoic lacunae (6 cases), by hyperechoic stripes (5 cases), and by muscular hernia (1 case); in 1 case, partial disconnection of a muscular insertion was demonstrated. Thus, we believe muscle-tendon US to be a valuable technique for both diagnostic and nosologic purposes, for the method allows simple cervical sprain to be discriminated from sprains which are complicated by organic muscular lesions. We suggest that the cervical sprain traumas where a muscular lesion due to tearing can be demonstrated be defined as "complex" traumas. PMID:1579667

    Altered skeletal muscle mitochondrial function contributes to the pathophysiological stress response to burns. However, the acute and chronic impact of burn trauma on skeletal muscle bioenergetics remains poorly understood. Here, we determined the temporal relationship between burn trauma and mitochondrial function in murine skeletal muscle local to and distal from burn wounds. Male BALB/c mice (8-10 weeks old) were burned by submersion of the dorsum in water (∼ 95 °C) to create a full thickness burn on ∼ 30% of the body. Skeletal muscle was harvested spinotrapezius underneath burn wounds (local) and the quadriceps (distal) of sham and burn treated mice at 3h, 24h, 4d and 10d post-injury. Mitochondrial respiration was determined in permeabilized myofiber bundles by high-resolution respirometry. Caspase 9 and caspase 3 protein concentration were determined by western blot. In muscle local to burn wounds, respiration coupled to ATP production was significantly diminished at 3h and 24h post-injury (P<0.001), as was mitochondrial coupling control (P<0.001). There was a 5- (P<0.05) and 8-fold (P<0.001) increase in respiration in response to cytochrome at 3h and 24h post burn, respectively, indicating damage to the outer mitochondrial membranes. Moreover, we also observed greater active caspase 9 and caspase 3 in muscle local to burn wounds, indicating the induction of apoptosis. Distal muscle mitochondrial function was unaltered by burn trauma until 10d post burn, where both respiratory capacity (P<0.05) and coupling control (P<0.05) were significantly lower than sham. These data highlight a differential response in muscle mitochondrial function to burn trauma, where the timing, degree and mode of dysfunction are dependent on whether the muscle is local or distal to the burn wound.

    Thromboelastography (TEG) with platelet mapping has been proposed as an assay to detect the presence of antiplatelet agents (APA), yet no study has evaluated TEG markers of platelet dysfunction in acute trauma patients stratified by the use of preinjury APA. We hypothesized that patients on preinjury APA would demonstrate prolonged TEG markers of platelet dysfunction compared with those not on preinjury APA. This retrospective review evaluated all trauma patients admitted to a Level I trauma center from February 2011 to April 2013 who received a TEG within the first 24 hours of admission. Patients were classified as receiving preinjury APA or no APA if their documented medications included either aspirin or adenosine diphosphate (ADP) antagonists, including clopidogrel, prasugrel, and ticagrelor. A total of 129 patients were included (APA, n = 35; no APA n = 94) in the study. The time from admission to the first TEG was similar (APA 175 ± 289 minutes versus no APA 216 ± 321 minutes, P = 0.5). There was no significant difference in TEG markers of platelet dysfunction, including per cent ADP inhibition (APA 61.7 ± 25.8% versus no APA 62.3 ± 28.8%; P = 0.91) or per cent arachidonic acid inhibition (APA 58.2 ± 31% versus no APA 53.8 ± 34%; P = 0.54). Both groups had similar proportion of severe platelet dysfunction, defined as ADP inhibition greater than 70 per cent (APA 40% versus no APA 40%; P = 0.8) and arachidonic acid inhibition greater than 70 per cent (APA 40% versus no APA 39%; P = 0.89). In conclusion, platelet dysfunction after major trauma is common. Therefore, TEG alone should not be used to evaluate for the presence of APA due to apparent lack of specificity. PMID:26874143

    Purpose: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. Methods: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. We evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. Results: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4-63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. Conclusions: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.

    Rationale of this study was to evaluate whether unfolded rib images enhance time efficiency in detection of rib fractures and time efficiency in patients with acute thoracic trauma. 51 subsequent patients with thoracic trauma underwent 64-slice computed tomography. 1mm thick axial slices were reformatted using a commercially available post-processing software application generating rotatable unfolded rib images. Diagnostic accuracy was evaluated by 3 readers and compared to multiplanar reformations of the original CT images. Reformation and evaluation times were recorded. 116 rib fractures were detected. The multiplanar reformation analysis yielded a sensitivity of 87.9%/93.9%/79.7% with a specificity of 97%/97%/82.2%, whilst the unfolded rib image analysis yielded a sensitivity of 94.8%/94.8%/92.2% and a specificity of 85.2/87.8%/82.4 (p=0.06/0.8/0.04) with high inter-observer agreement (k=0.79-0.85). The mean reading time for the multiplanar reformations was significantly longer (reader 1: 103.7 ± 27.1s/reader 2: 81.8 ± 40.6s/reader 3: 154.3 ± 39.2s) than the evaluation of the unfolded rib images (19.4 ± 4.9s/26.9 ± 15.0s/49.9 ± 18.7s; p<0.01). Concluding, the unfolded rib display reduces reading time for detection of rib fractures in acute thoracic trauma patients significantly and does not compromise the diagnostic accuracy significantly in experienced radiologists. However, unexperienced readers may profit from use of this display. PMID:26226916

    Introduction and objective Acute injury transiently lowers local mechanical pain thresholds at a limb. To elucidate the impact of painless (diabetic) neuropathy on this post-traumatic hyperalgesia, pressure pain perception thresholds after a skeletal foot trauma were studied in consecutive persons without and with neuropathy (i.e. history of foot ulcer or Charcot arthropathy). Design and methods A case–control study was done on 25 unselected clinical routine patients with acute unilateral foot trauma (cases: elective bone surgery; controls: sprain, toe fracture). Cases were 12 patients (11 diabetic subjects) with severe painless neuropathy and chronic foot pathology. Controls were 13 non-neuropathic persons. Over 1 week after the trauma, cutaneous pressure pain perception threshold (CPPPT) and deep pressure pain perception threshold (DPPPT) were measured repeatedly, adjacent to the injury and at the opposite foot (pinprick stimulators, Algometer II®). Results In the control group, post-traumatic DPPPT (but not CPPPT) at the injured foot was reduced by about 15–25%. In the case group, pre- and post-operative CPPPT and DPPPT were supranormal. Although DPPPT fell post-operatively by about 15–20%, it remained always higher than the post-traumatic DPPPT in the control group: over musculus abductor hallucis 615 kPa (kilopascal) versus 422 kPa, and over metatarsophalangeal joint 518 kPa versus 375 kPa (medians; case vs. control group); CPPPT did not decrease post-operatively. Conclusion Physiological nociception and post-traumatic hyperalgesia to pressure are diminished at the foot with severe painless (diabetic) neuropathy. A degree of post-traumatic hypersensitivity required to ‘pull away’ from any one, even innocuous, mechanical impact in order to avoid additional damage is, therefore, lacking. PMID:25397867

    PubMed Central

    Juan, Francisco J

    2004-01-01

    Background Whiplash associated disorder is commonly linked to motor vehicle accidents and sports injuries. Cervical injury is attributed to rapid extension followed by neck flexion. The exact pathophysiology of whiplash is uncertain but probably involves some degree of aberrant muscle spasms and may produce a wide range of symptoms. The most commonly prescribed pharmacological agents for initial treatment of whiplash-associated pain are oral muscle relaxants and nonsteroidal anti-inflammatory drugs. However, potential systemic adverse effects limit these agents. Physical interventions such as mobilization, manipulation, and exercises have proved beneficial for pain and dysfunction but only on a time-limited basis. Little evidence suggests that physical therapy specifically aimed at the musculature (e.g., transcutaneous electrical nerve stimulation, ultrasonography, heat, ice, and acupuncture) improves prognosis in acute whiplash associated disorder. A new approach to treatment is the use of botulinum toxin, which acts to reduce muscle spasms. Methods/design This is a prospective, randomized, controlled clinical trial and botulinum toxin-A (Botox®) injections will be compared with placebo injections. The primary objective is to determine the efficacy of Botox® in the management of musculoskeletal pain in whiplash associated disorders. Discussion Botulinum toxin type-A toxin has been studied in small trials on whiplash associated disorder patients and has generally been found to relieve pain and improve range of motion. Specifically, we seek to assess the efficacy of Botox® in reducing pain and to improve the cervical spine range of movement, during the 6-month trial period. PMID:15018625

    Estimates of the lifetime prevalence of posttraumatic stress disorder (PTSD) in American adults range from 6.4–6.8%. PTSD is associated with increased risk for comorbid major depression, substance use disorder, suicide, and a variety of other mental and physical health conditions. Given the negative sequelae of trauma/PTSD, research has focused on identifying efficacious interventions that could be administered soon after a traumatic event to prevent or reduce the subsequent incidence of PTSD. While early psychosocial interventions have been shown to be relatively ineffective, early (secondary) pharmacological interventions have shown promise. These pharmacological approaches are largely based on the hypothesis that disruption of altered stress hormone levels and the consequent formation of trauma memories could protect against the development of PTSD. The present manuscript reviews the literature regarding the role of peri-traumatic stress hormones as risk factors for the development of PTSD and reviews evidence for the efficacy of exogenously modulating stress hormone levels to prevent/buffer the development of PTSD symptoms. Whereas prior literature has focused primarily on either child or adult studies, the present review incorporates both child and adult studies in a developmental approach to understanding risk for PTSD and how pharmacological modulation of acute memories may buffer the development of PTSD symptoms.

    Congenital absence of cervical spine pedicle can be easily misdiagnosed as facet dislocation on plain radiographs especially in the acute trauma setting. Additional imaging, including computed tomography (CT)-scan with careful interpretation is required in order to not misdiagnose cervical posterior arch malformation with subsequent inappropriate management. A 39-year-old patient presented to the emergency unit of our university hospital after being trampled by a cow over her back and head followed by loss of consciousness, retrograde amnesia and neck pain. Her initial cervical CT-scan showed possible C5-C6 dislocation, then, it became clear that her problem was a misdiagnosed congenital cervical abnormality. Patient was treated symptomatically without consequences. The congenital absence of a cervical pedicle is a very unusual condition that is easily misdiagnosed. Diagnosis can be accurately confirmed with a CT-scan of the cervical spine. Symptomatic conservative treatment will result in resolution of the symptoms. PMID:26605026

    Objectives An initial stratification of acute whiplash patients into seven risk-strata in relation to 1-year work disability as primary outcome is presented. Design The design was an observational prospective study of risk factors embedded in a randomised controlled study. Setting Acute whiplash patients from units, general practitioners in four Danish counties were referred to two research centres. Participants During a 2-year inclusion period, acute consecutive whiplash-injured (age 18–70 years, rear-end or frontal-end car accident and WAD (whiplash-associated disorders) grades I–III, symptoms within 72 h, examination prior to 10 days postinjury, capable of written/spoken Danish, without other injuries/fractures, pre-existing significant somatic/psychiatric disorder, drug/alcohol abuse and previous significant pain/headache). 688 (438 women and 250 men) participants were interviewed and examined by a study nurse after 5 days; 605 were completed after 1 year. A risk score which included items of initial neck pain/headache intensity, a number of non-painful complaints and active neck mobility was applied. The primary outcome parameter was 1-year work disability. Results The risk score and number of sick-listing days were related (Kruskal-Wallis, p<0.0001). In stratum 1, less than 4%, but in stratum 7, 68% were work-disabled after 1 year. Early work assessment (p<0.0001), impact of the event questionnaire (p<0.0006), psychophysical pain measures being McGill pain questionnaire parameters (p<0.0001), pressure pain algometry (p<0.0001) and palpation (p<0.0001) showed a significant relationship with risk stratification. Analysis Findings confirm previous studies reporting intense neck pain/headache and distress as predictors for work disability after whiplash. Neck-mobility was a strong predictor in this study; however, it was a more inconsistent predictor in other studies. Conclusions Application of the risk assessment score and use of the risk strata

    Angiogenesis is a key event during tissue regeneration, but the intimate mechanisms controlling this process are still largely unclear. Therefore, the cellular and molecular interplay along normal tissue regeneration should be carefully unveiled. To this matter, we investigated by xMAP assay the dynamics of some angiogenic factors known to be involved in tissue repair, such as follistatin (FST), Placental Growth Factor-2 (PLGF-2), epidermal growth factor (EGF), betacellulin (BTC), and amphiregulin (AREG) using an animal model that mimics acute muscle contusion injuries. In situ immunofluorescence was used for the evaluation and tissue distribution of their cellular sources. Tissue levels of explored factors increased significantly during degeneration and inflammatory stage of regeneration, peaking first week postinjury. However, except for PLGF-2 and EGF, their levels remained significantly elevated after the inflammatory process started to fade. Serum levels were significantly increased only after 24 h for AREG and EGF. Though, for all factors except FST, the levels in injured samples did not correlate with serum or contralateral tissue levels, excluding the systemic influence. We found significant correlations between the levels of EGF and AREG, BTC, FST and FST and AREG in injured samples. Interstitial cells expressing these factors were highlighted by in situ immunolabeling and their number correlated with measured levels dynamics. Our study provides evidence of a dynamic level variation along the regeneration process and a potential interplay between selected angiogenic factors. They are synthesized, at least partially, by cell populations residing in skeletal muscle interstitium during regeneration after acute muscle trauma. PMID:26260512

    Background In a majority of cases, whiplash injuries are a domain of conservative therapy. Nevertheless it remains unclear whether physical therapy is of medical or economic benefit in patients with whiplash injuries. Methods Seventy patients with acute Quebec Task Force (QTF) grade II whiplash injuries were randomized to two therapy groups and received either active (APT) or passive (PPT) physical therapy. Patients were compared with regard to pain and range of motion with data obtained in an earlier study from a group with grade II whiplash injuries in which the therapy recommendation had been "act as usual" (AAU; n = 20). The above-mentioned parameters were assessed at 24 hours and two months after the injury. Furthermore patients' period of disability was documented after two months. Results After two months, patients in both the APT and PPT groups showed significant improvement in the median period of disability (active: 14 days; passive: 14 days) compared to the AAU group (49 days). No group difference was observed with regard to median improvement in range of motion (active: 120°; passive: 108°; activity as usual: 70°). The median pain reduction was significantly greater in the APT group (50.5) than in the PPT (39.2) or AAU group (28.8). Conclusion Our data show that active physical therapy results in enhanced pain reduction and shortening of post-injury disability. Therefore, active physical therapy should be considered the treatment of choice in patients with QTF grade II whiplash injuries. Trial registration The study complied with applicable German law and with the principles of the Helsinki Declaration and was approved by the institutional ethics commission. PMID:19149880

    Background In more than 90% of whiplash accidents a good explanation regarding the association between trauma mechanism, organic pathology, and persistent symptoms has failed to be provided. Objective We predicted that the severity of chronic whiplash-associated disorder (WAD), measured as number of whiplash symptoms, pain duration, pain-related disability, and degree of somatisation would be associated with the number of post-traumatic stress disorder symptoms (PTSD). Secondly, we expected attachment-anxiety to be a vulnerability factor in relation to both PTSD and WAD. Design Data were collected from 1,349 women and 360 men suffering from WAD from the Danish Society for Polio, Traffic, and Accident Victims. The PTSD symptoms were measured by the Harvard Trauma Questionnaire. All three core PTSD clusters were included: re-experiencing, avoidance, and hyperarousal. Attachment security was measured along the two dimensions, attachment-anxiety and attachment-avoidance, by the Revised Adult Attachment Scale. Results PTSD symptoms were significantly related to the severity of WAD. In particular, the PTSD clusters of avoidance and hyperarousal were associated with the number of whiplash symptoms, disability, and somatisation. Attachment-anxiety was significantly related to PTSD symptoms and somatisation but not to pain and disability. A co-morbidity of 38.8% was found between the PTSD diagnosis and WAD, and about 20% of the sample could be characterised as securely attached. Conclusions The PTSD clusters of avoidance and hyperarousal were significantly associated with severity of WAD. The study emphasises the importance of assessing PTSD symptomatology after whiplash injury. Furthermore, it highlights that attachment theory may facilitate the understanding of why some people are more prone to develop PTSD and WAD than others. PMID:22893825

    Two rheologically active and 8 vasoactive and metabolically active substances were compared in eight independent studies, some of which were randomised and double blind, on 400 patients who had suffered acute acoustic trauma. The control group was given saline. Spontaneous recovery was excluded as far as possible. The following substances were tested: Dextran 40, hydroxyethyl starch 40/0.5, naftidrofurylhydrogenoxalate, Vinpocetin, betahistine, pentoxifylline, flunaricine, Regeneresen AU 4 and 0.9% saline. All groups showed superior results to the control group in both long-term and short-term tests with respect to hearing gain and tinnitis improvement. The rheologically effective substances showed no statistically significant variations. None of the vasoactive or metabolically active substances used as adjunctive therapy improved the results achieved with rheologically effective substances alone. These results demonstrate that acute acoustic trauma can be most effectively treated by rheologically active substances; vasoactive and metabolically active substances are unnecessary. Hyperbaric oxygenation is advantageous as an adjunctive therapy. PMID:2432041

    Coronary artery dissection and aneurysm culminating in acute myocardial infarction are rare after blunt chest trauma. We are reporting a case of a previously healthy 52-year-old man who presented with right inferior lobe contusion, pleural effusion, right interlobar fissure effusion, bone fracture of right fourth rib, and acute inferior wall myocardial infarction and who experienced blunt trauma in his right chest wall by an airbag deployment in a car accident. Coronary angiography showed an aneurysm in the middle of right coronary artery with 70% afferent narrowing just distal to the aneurysm with no visible atherosclerotic lesion. A 4.0×20 mm TEXUS Liberté stent in the lesion was deployed, and a good coronary flow was obtained without residual stenosis and the aneurysm vanished. PMID:26319191

    We present a systematic review of prospective cohort studies. Our aim was to assess prognostic factors associated with functional recovery of patients with whiplash injuries. The failure of some patients to recover following whiplash injury has been linked to a number of prognostic factors. However, there is some inconsistency in the literature and there have been no systematic attempts to analyze the level of evidence for prognostic factors in whiplash recovery. Studies were selected for inclusion following a comprehensive search of MEDLINE, EMBASE, CINAHL, the database of the Dutch Institute of Allied Health Professions up until April 2002 and hand searches of the reference lists of retrieved articles. Studies were selected if the objective was to assess prognostic factors associated with recovery; the design was a prospective cohort study; the study population included at least an identifiable subgroup of patients suffering from a whiplash injury; and the paper was a full report published in English, German, French or Dutch. The methodological quality was independently assessed by two reviewers. A study was considered to be of 'high quality' if it satisfied at least 50% of the maximum available quality score. Two independent reviewers extracted data and the association between prognostic factors and functional recovery was calculated in terms of risk estimates. Fifty papers reporting on twenty-nine cohorts were included in the review. Twelve cohorts were considered to be of 'high quality'. Because of the heterogeneity of patient selection, type of prognostic factors and outcome measures, no statistical pooling was able to be performed. Strong evidence was found for high initial pain intensity being an adverse prognostic factor. There was strong evidence that for older age, female gender, high acute psychological response, angular deformity of the neck, rear-end collision, and compensation not being associated with an adverse prognosis.

    Accumulating evidence suggests traumatic experience can rapidly alter brain activation associated with emotion processing. However, little is known about acute changes in emotion neurocircuits that underlie PTSD symptom development. To examine acute alterations in emotion circuit activation and structure that may be linked to PTSD symptoms, thirty-eight subjects performed a task of appraisal of emotional faces as their brains were functionally and structurally studied with MRI at both two weeks and three months after motor vehicle collision (MVC). As determined by symptoms reported in the PTSD Checklist at three months, sixteen survivors developed probable PTSD, whereas the remaining 22 did not meet criteria for PTSD diagnosis (non-PTSD). The probable PTSD group had greater activation than the non-PTSD group in dorsal and ventral medial prefrontal cortex (dmPFC and vmPFC) while appraising fearful faces within two weeks after MVC and in left insular cortex (IC) three months after MVC. dmPFC activation at two weeks significantly positively correlated with PTSD symptom severity at two weeks (R = 0.462, P = 0.006) and three months (R = 0.418, p = 0.012). Changes over time in dmPFC activation and in PTSD symptom severity were also significantly positively correlated in the probable PTSD group (R = 0.641, P = 0.018). A significant time by group interaction was found for volume changes in left superior frontal gyrus (SFG, F = 6.048, p = 0.019) that partially overlapped dmPFC active region. Between two weeks and three months, left SFG volume decreased in probable PTSD survivors. These findings identify alterations in frontal cortical activity and structure during the early post-trauma period that appear to be associated with development of PTSD symptoms. PMID:27415431

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to be effective in the treatment of acute soft tissue injuries. However, taken orally, NSAIDs have a definite incidence of gastro-intestinal toxicity. Since acute soft tissue trauma is normally localised, use of a topical NSAID may eliminate this undesirable side-effect. This study was designed to evaluate the efficacy and safety of a topical NSAID, biphenylacetic acid 3% gel (Traxam) in the treatment of soft tissue trauma. Thirty-two patients (22 males and 10 females) with acute soft tissue trauma were enrolled at the Department of Orthopaedic Surgery, National University Hospital, Singapore from 7 June 1988 to 28 March 1989. Each patient was treated for a period of one week with bipenylacetic acid 3% gel (Traxam), 60 mg three times a day. Statistically significant improvement was found in pain, swelling and functional impairment in all patients assessed at day 3 and day 7 after the injury. The speed of recovery was enhanced. The medication was found to be well tolerated and safe. PMID:1776001

    In the Swiss army instructors and fortifications guards are exposed to firearms' noise which harms the ear. It was investigated whether the decline in the cases of acute acoustic traumas in non-professional soldiers serving in the army from 1987 to 1996 also was detectable in army instructors and fortifications guards (professional soldiers) and whether these persons were wearing hearing aids (as an indicator of hearing loss) more often than the average of the male Swiss population. First, we analyzed a historical time series of the incidence density of acute acoustic traumas in non-professional soldiers as well as in army instructors and fortifications guards. Second, we compared the prevalence rate of wearing a hearing aid in army instructors and fortifications guards with the male Swiss population. The incidence density for acute acoustic traumas in army instructors and fortifications guards observed over ten years showed no significant change whereas among non-professional soldiers a strong decline (-12% per year) was observed. The prevalence rate of wearing a hearing aid in army instructors and fortifications guards was significantly higher (RR 3.91 [95% CI 3.09-4.96]) than in the male Swiss population. These results suggest increased hearing impairment among army instructors and fortifications guards which is probably due to the high exposure to impulse noise events (occupational disease). It is recommended that these persons be subjected to a compulsory prevention program. PMID:10588036

    In acute acoustic trauma (AAT), excessive noise exposure causes rupture of cell membranes and decreased cochlear blood flow. This leads to decreased oxygen tension in inner ear fluids and reduction of a variety of different oxygen-dependent cellular activities. Hyperbaric oxygen treatment (HBO) may help the cells suffering from hypoxia to survive. We exposed male Wistar rats to 60 impulses of 162-dB SPL from a 7.62-mm assault rifle equipped with a blank adaptor. After the exposure, 15 animals were given HBO treatment for 90 min daily for 10 consecutive days at 0.25 MPa. After a survival time of 4 weeks, auditory brainstem responses were measured and the left cochleae processed for light microscopy. The impulse noise caused permanent damage to the cochlea of all animals, with the most severe lesions in the lower middle coil, where a significantly smaller number of hair cells was missing in the HBO-treated group. The morphological damage was also reflected in function, as measured by auditory brainstem responses, which showed the greatest threshold shifts at 6.0, 8.0 and 10.0 kHz. PMID:10909001

    The purpose of this randomized study was to evaluate the early effect of the treatment of acute acoustic trauma (AAT) with steroids and piracetam in a sample of 52 young soldiers who were exposed to intense gunfire noise (G3 rifle). These patients were divided into three groups: (1) group A (20 patients) in which the treatment began within the first hour after the AAT, (2) group B (17 patients) in which the treatment started more than 1 h later and less than 16 h after the AAT and (3) group C (15 patients) in which the treatment began after 24 h or more. One month after the treatment onset, 36 (69%) patients of all the groups showed hearing improvement (complete-partial recovery) in the pure tone audiometry. The greater number of patients who showed complete recovery after AAT was noted in group A (65%) compared to group B (23.5%) and C (13.3%). Moreover, in group A, in the final audiogram, the averaged hearing threshold was statistically better (P < 0.001) than that of groups B and C. In spite of the lack of control group, our data demonstrated the possible effectiveness of the immediate onset of treatment of AAT. PMID:18463885

    This prospective study of acute acoustic trauma (AAT) from exposure to impulse noise during compulsory military service focused on three issues the number of shot or explosion impulses that the conscript was exposed to at the time of AAT, distance of injured ear from causal firearm, and the circumstances under which AAT occurred protected ears. The series includes 449 consecutive, verified cases of AAT seen at the Central Military Hospital in Helsinki, Finland, in the period 1989-1993. AAT usually occurred during combat training (87%) as a result of exposure to impulses from small arms (83%). In 41%. AAT was caused by a single shot or detonation impulse. As many as 92% of all AATs occurred within 2 m of the causal firearm. Fourteen percent were wearing hearing protectors when the accident took place, but every third had badly fitting protectors or had neglected safety regulations and used insufficient protection. Of all AATs caused by one noise impulse in protected ears. 83% were attributable to heavy arms and only 14% to small arms. The results of the study suggest that combined use of earmuffs and earplugs in association with a safe distance of over 5 m from the noise source gives adequate protection against AAT. However, for conscripts using certain heavy arms e.g. hazooka. more effective hearing protection should be developed. PMID:9187006

    Background Previous clinical studies have identified the cervical facet joint, including the capsular ligaments, as sources of pain in whiplash patients. The goal of this study was to determine whether whiplash caused increased capsular ligament laxity by applying quasi-static loading to whiplash-exposed and control capsular ligaments. Methods A total of 66 capsular ligament specimens (C2/3 to C7/T1) were prepared from 12 cervical spines (6 whiplash-exposed and 6 control). The whiplash-exposed spines had been previously rear impacted at a maximum peak T1 horizontal acceleration of 8 g. Capsular ligaments were elongated at 1 mm/s in increments of 0.05 mm until a tensile force of 5 N was achieved and subsequently returned to neutral position. Four pre-conditioning cycles were performed and data from the load phase of the fifth cycle were used for subsequent analyses. Ligament elongation was computed at tensile forces of 0, 0.25, 0.5, 0.75, 1.0, 2.5, and 5.0 N. Two factor, non-repeated measures ANOVA (P<0.05) was performed to determine significant differences in the average ligament elongation at tensile forces of 0 and 5 N between the whiplash-exposed and control groups and between spinal levels. Findings Average elongation of the whiplash-exposed capsular ligaments was significantly greater than that of the control ligaments at tensile forces of 0 and 5 N. No significant differences between spinal levels were observed. Interpretation Capsular ligament injuries, in the form of increased laxity, may be one component perpetuating chronic pain and clinical instability in whiplash patients. PMID:17959284

    An analysis was made of 1176 whiplash-type neck distortions taken from a total of 3838 restrained car driver incident reports. The percentage of whiplash-type neck distortion among injured drivers increased from less than 10% in 1985 to over 30% in 1997. Most occurred in head-on crashes or crashes with multiple collisions; only 15% occurred in rear-end collisions. More than 1,000 questionnaires were sent to the injured to find out about the duration and type of complaints caused by their cervical spine injury. Although only 138 (12%) returned the questionnaire, which may not be a representative sample, a further analysis was carried out. Of the 138, 121 (88%) indicated that they had suffered or were still suffering from their symptoms. The percentages of the various complaints were as follows: pain (74%), tension (6%) and stiffness (5%) in the head (27%), neck (55%) and shoulder (8%). The duration of the complaints was longest after multiple collisions and when the onset of complaints was longer than 24 h after trauma. Women and elderly persons predominated slightly in the group with longer duration of complaints. A correlation between the severity of the accompanying injuries and duration of complaints was found. Lack of adequate follow-up for patients with less severe injuries posed considerable difficulties for this retrospective study. In order to better evaluate this problem, prospective studies are necessary, with documentation including diagnosis, treatments, complaint duration and type. PMID:10823426

    Research on the psychobiological sequelae of trauma has typically focused on long-term alterations in individuals with chronic posttraumatic stress disorder (PTSD). Far less is known about the nature and course of psychobiological risk factors for PTSD during the acute aftermath of trauma. In this review, we summarize data from prospective studies focusing on the relationships among sympathetic nervous system activity, hypothalamic-pituitary-adrenal function, coping strategies and PTSD symptoms during the early recovery (or non-recovery) phase. Findings from pertinent studies are integrated to inform psychobiological profiles of PTSD-risk in children and adults in the context of existing models of PTSD-onset and maintenance. Data regarding bidirectional relations between coping strategies and stress hormones is reviewed. Limitations of existing literature and recommendations for future research are discussed.

An interdisciplinary treatment development team was comprised of trauma surgical, clinical psychiatric and mental health services “change agents” who spanned the boundaries between front-line trauma center clinical care and acute care policy. Mixed method clinical epidemiologic and clinical ethnographic studies informed the development of PTSD screening and intervention procedures. Results Two-hundred and seven acutely injured trauma survivors with high early PTSD symptom levels were randomized into the study. The stepped collaborative care model integrated care management (i.e., posttraumatic concern elicitation and amelioration, motivational interviewing, and behavioral activation) with cognitive behavioral therapy and pharmacotherapy targeting PTSD. The model was feasibly implemented by front-line acute care MSW and ARNP providers. Conclusions Stepped care protocols targeting PTSD may enhance the population impact of early interventions developed for survivors of individual and mass trauma by extending the reach of collaborative care interventions to acute care medical settings and other non-specialty posttraumatic contexts.

    Objective Higher body mass index (BMI) is associated with increased risk of acute kidney injury (AKI) after major trauma. Since BMI is non-specific, reflecting lean, fluid, and adipose mass, we evaluated the use of computed tomography (CT) to determine if abdominal adiposity underlies the BMI-AKI association. Design Prospective cohort study. Setting Level I Trauma Center of a university hospital. Patients Patients older than 13 years with an Injury Severity Score ≥16 admitted to the trauma intensive care unit were followed for development of AKI over five days. Those with isolated severe head injury or on chronic dialysis were excluded. Interventions None Measurements and Main Results Clinical, anthropometric, and demographic variables were collected prospectively. CT images at the level of the L4-5 intervertebral disc space were extracted from the medical record and used by two operators to quantitate visceral and subcutaneous adipose tissue (VAT and SAT, respectively) areas. AKI was defined by Acute Kidney Injury Network (AKIN) creatinine and dialysis criteria. Of 400 subjects, 327 (81.8%) had CT scans suitable for analysis: 264/285 (92.6%) blunt trauma subjects, 63/115 (54.8%) penetrating trauma subjects. VAT and SAT areas were highly correlated between operators (ICC>0.999, p<0.001 for each) and within operator (ICC>0.999, p<0.001 for each). In multivariable analysis, the standardized risk of AKI was 15.1% (95% CI 10.6%,19.6%), 18.1% (14%,22.2%), and 23.1% (18.3%,27.9%) at the 25th, 50th, and 75th percentiles of VAT area, respectively (p=0.001), with similar findings when using SAT area as the adiposity measure. Conclusions Quantitation of abdominal adiposity using CT scans obtained for clinical reasons is feasible and highly reliable in critically ill trauma patients. Abdominal adiposity is independently associated with AKI in this population, confirming that excess adipose tissue contributes to the BMI-AKI association. Further studies of the potential

    The Acute Psychological Trauma (APT) Study was a collaboration between an acute care hospital, a specialized multidisciplinary program designed to meet the mental health needs of injured workers, and a large urban public transit system. The overall purpose was to evaluate a Best Practices Intervention (BPI) for employees affected by acute psychological trauma compared to a Treatment as Usual (TAU) group. The specific purpose is to discuss facilitators and barriers that were recognized in implementing and carrying out mental health research in a workplace setting. Over the course of the APT study, a joint implementation committee was responsible for day-to-day study operations and made regular observations on the facilitators and barriers that arose throughout the study. The facilitators to this study included the longstanding relationships among the partners, increased recognition for the need of mental health research in the workplace, and the existence of a community advisory committee. The significant barriers to doing this study of mental health research in the workplace included differences in organizational culture, inconsistent union support, co-interventions, and stigma. Researchers and funding agencies need to be flexible and provide additional resources in order to overcome the barriers that can exist doing workplace mental health research. PMID:26967029

    Whiplash injury usually occurs in people who suffered an automobile accident, but also occurs as a result of physical assault and other mechanisms. Diagnosis and initial management of the patient by the emergency physician or orthopedist, and prescribing indications, are taken into account by two forensic intervention specialists. One of these is the medical officer, who, through analysis of the injury mechanism, establishes a cause-effect relationship and concludes whether the accident suffered by a worker it is related to work or not, determines how long the worker will remain disabled and if the injury caused permanent disability under Federal Labor Law. The medical examiner by injury classification assists the Public Ministry so that it can frame the crime of injury to the Criminal Code of Federal District. For these reasons a review of medical information about the mechanism of injury, diagnosis, treatment and healing time was performed to help both specialists to standardize their approach in their daily activities.

    Whiplash injury criteria are based upon the hypothesis that neck injuries are caused by excessive loads, displacements, or head/T1 relative acceleration and velocity. The objectives of this study were to evaluate and compare the whiplash injury criteria (IV-NIC, NIC, Nkm, Nij, and NDC) during simulated rear impacts of a new Human Model of the Neck (HUMON) with and without an active head restraint (AHR). HUMON consisted of a neck specimen mounted to the torso of BioRID II and carrying an anthropometric head stabilized with muscle force replication. HUMON was seated and secured in a Kia Sedona seat with AHR on a sled. Rear impacts (7.1 and 11.1g) were simulated with the AHR in five different positions followed by an impact with no HR. Statistical differences (P < 0.05) were determined in the peak NIC and NDC due to the AHR, as compared to no HR, and in the peak IV-NIC relative to physiologic limits. Linear regression analyses identified correlation between IV-NIC and NIC, Nkm, Nij, and NDC (R(2) > or = 0.35 and P < 0.001). The AHR caused significant decreases in peak NIC and NDC as compared to no HR. The IV-NIC identified significantly increased motion above the physiologic limit at the middle and lower cervical spine with and without the AHR. Correlation was observed between IV-NIC and NIC, Nkm, Nij, and NDC. Extrapolation using the present correlations and the IV-NIC injury thresholds suggests neck injuries may occur at peak NIC of 14.4m(2)/s(2), Nkm of 0.33, or Nij of 0.09. Nonphysiologic spinal rotation at one or more spinal levels may occur even if head/T1 motions are small. PMID:19887145

    Neck pain is the cardinal symptom following whiplash injuries. The trauma mechanism could theoretically lead to both soft tissue and bone injury that could be visualised by means of MRI. From previous quite small trials it seems that MRI does not demonstrate significant tissue damage. Large prospectively followed cohorts are needed to identify possible clinically relevant MRI findings. The objective of this trial was to evaluate (1) the predictive value of cervical MRI after whiplash injuries and (2) the value of repeating MRI examinations after 3 months including sequences with flexion and extension of the cervical spine. Participants were included after rear-end or frontal car collisions. Patients with fractures or dislocations diagnosed by standard procedures at the emergency unit were not included. MRI scans of the cervical spine were performed at baseline and repeated after 3 months. Clinical follow-ups were performed after 3 and 12 months. Outcome parameters were neck pain, headache, neck disability and working ability. A total of 178 participants had a cervical MRI scan on average 13 days after the injury. Traumatic findings were observed in seven participants. Signs of disc degeneration were common and most frequent at the C5–6 and C6–7 levels. Findings were not associated with outcome after 3 or 12 months. The population had no considerable neck trouble prior to the whiplash injury and the non-traumatic findings represent findings to be expected in the background population. Trauma-related MRI findings are rare in a whiplash population screened for serious injuries in the emergency unit and not related to a specific symptomatology. Also, pre-existing degeneration is not associated with prognosis. PMID:18512085

  12. The Acute Coagulopathy of Trauma is due to Impaired Initial Thrombin Generation but not Clot Formation or Clot Strength

    The Acute Coagulopathy of Trauma (ACOT) has been described as a very early hypocoagulable state, but the mechanism remains controversial. One proposed mechanism is tissue hypoperfusion leading to protein C activation, with subsequent inhibition of Factors V and VIII. Variability in trauma has impeded the use of clinical data towards the elucidation of the mechanisms of ACOT, but thrombelastography (TEG) may provide insight by assessing hemostatic function from initial thrombin activation to fibrinolysis. We hypothesized that, in a controlled animal model of trauma/hemorrhagic shock, clotting factor dysfunction is the predominant mechanism in early ACOT. Methods Rats anesthetized by inhaled isoflurane (n=6) underwent laparotomy, and hemorrhage was induced to maintain a MAP of 35 mmHg for 30 minutes. Rats were then resuscitated with twice their shed blood volume in normal saline. TEG was performed at baseline, shock, and post-resuscitation periods. No heparin was given. Statistical analysis was performed by ANOVA with post-hoc Fisher’s test. Results Coagulation factor function was significantly impaired in the early stages of trauma/hemorrhagic shock. TEG R and SP-values were significantly increased from baseline to shock (p<0.001) and from shock to post-resuscitation periods (p<0.05). Delta (R-SP), a measure of thrombin generation, showed a significant increase (p<0.05) from baseline to shock. No significant changes were found in K, Angle, MA, and LY30 values. Conclusion Clotting factor derangement leading to impaired thrombin generation is the principle etiology of ACOT in this model and not the dynamics of clot formation, fibrin cross-linking, clot strength/platelet function, or fibrinolysis.

    We investigated the effect of low-level laser radiation on rescuing hair cells of the cochlea after acute acoustic trauma and hearing loss. Nine rats were exposed to noise. Starting the following day, the left ears (NL ears) of the rats were irradiated at an energy output of 100 to 165 mW/cm2 for 60 min for 12 days in a row. The right ears (N ears) were considered as the control group. Frequency-specific hearing levels were measured before the noise exposure and also after the 1st, 3rd to 5th, 8th to 10th and 12th irradiations. After the 12th treatment, hair cells were observed using a scanning electron microscope. Compared to initial hearing levels at all frequencies, thresholds increased markedly after noise exposure. After the 12th irradiation, hearing threshold was significantly lower for the NL ears compared to the N ears. When observed using an electron microscope, the number of hair cells in the middle turn of the NL ears was significantly larger than that of the N ears. Our findings suggest that low-level laser irradiation promotes recovery of hearing thresholds after acute acoustic trauma.

    Background Severe blunt chest trauma is associated with high mortality. Sepsis represents a serious risk factor for mortality in acute respiratory distress syndrome (ARDS). In septic patients with ARDS complement activation products were found to be elevated in the plasma. In single models like LPS or trauma complement has been studied to some degree, however in clinically highly relevant double hit models such as the one used here little data is available. Here, we hypothesized that absence of C5 is correlated with a decreased inflammatory response in trauma induced septic acute lung injury. Methods 12 hrs after DH in mice the local and systemic cytokines and chemokines were quantified by multiplex bead array or ELISA, activated caspase-3 by western blot. Data were analyzed using one-way ANOVA followed by post-hoc Sidak’s multiple comparison test (significance, p≤ 0.05). Results In lung tissue interleukin (IL)-6, monocyte chemo attractant protein-1 (MCP-1) and granulocyte-colony stimulating factor (G-CSF) was elevated in both C5-/- mice and wildtype littermates (wt), whereas caspase-3 was reduced in lungs after DH in C5-/- mice. Systemically, reduced keratinocyte-derived chemokine (KC) levels were observed after DH in C5-/- compared to wt mice. Locally, lung myeloperoxidase (MPO), protein, IL-6, MCP-1 and G-CSF in brochoalveolar lavage fluid (BALF) were elevated after DH in C5-/- compared to wt. Conclusions In the complex but clinically relevant DH model the local and systemic inflammatory immune response features both, C5-dependent and C5-independent characteristics. Activation of caspase-3 in lung tissue after DH was C5-dependent whereas local inflammation in lung tissue was C5-independent. PMID:27437704

    Cardiac complications of chest trauma range from arrhythmias to valvular avulsions to myocardial contusion, rupture, and rarely myocardial infarction. We describe a case of a young patient with blunt chest trauma after a motor vehicle accident in whom the diagnosis of myocardial infarction was established a week later because no electrocardiogram or cardiac biomarkers were obtained on presentation. Retrospective review of contrast-enhanced computed tomography (CT) of the chest done on presentation demonstrated a perfusion defect in the distribution of the left anterior descending artery (LAD). Subsequent coronary angiography demonstrated dissection in the proximal LAD. Our case illustrates the importance of electrocardiography and contrast-enhanced chest CT in initial evaluation of patients with blunt chest trauma and suspected injury to the coronary arteries.

    Traditionally, in free flap cover of lower limb injuries, every attempt is made to perform anastomoses proximal to the zone of injury. We report on the success of anastomoses within the zone of trauma, at the level of the fracture, avoiding further dissection and exposure. The records of free flap reconstructions for fractures of the lower extremity at a tertiary trauma centre between 2004 and 2010 were retrospectively reviewed. A total of 48 lower limb fractures required free flap reconstruction, performed at 28 days post injury (0-275 days). Anastomoses were proximal (21), distal (5) or within the zone of trauma (22). There was no significant difference (p > 0.05) in return to theatre, revision of anastomosis or flap survival between groups. Of the 22 performed within the zone of injury, five returned to theatre but only two for revision of anastomosis and 20 (91%) of these flaps survived. Of the 48 free flaps, arterial anastomoses were end to end in 34 (71%) and end to side in 14 (30%). There was no significant difference (p > 0.05) in return to theatre, revision of anastomosis or flap survival between the end-to-end and end-to-side groups. There was a tendency for arterial anastomoses to be performed end to end outside the zone of trauma (23/26) compared to within the zone of trauma (11/22). Our data suggest that free flap anastomoses can be performed safely in the zone of trauma in lower limb injuries. PMID:27108076

  17. The acute management of trauma hemorrhage: a systematic review of randomized controlled trials

    2011-01-01

    Introduction Worldwide, trauma is a leading cause of death and disability. Haemorrhage is responsible for up to 40% of trauma deaths. Recent strategies to improve mortality rates have focused on optimal methods of early hemorrhage control and correction of coagulopathy. We undertook a systematic review of randomized controlled trials (RCT) which evaluated trauma patients with hemorrhagic shock within the first 24 hours of injury and appraised how the interventions affected three outcomes: bleeding and/or transfusion requirements; correction of trauma induced coagulopathy and mortality. Methods Comprehensive searches were performed of MEDLINE, EMBASE, CENTRAL (The Cochrane Library Issue 7, 2010), Current Controlled Trials, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform (ICTRP) and the National Health Service Blood and Transplant Systematic Review Initiative (NHSBT SRI) RCT Handsearch Database. Results A total of 35 RCTs were identified which evaluated a wide range of clinical interventions in trauma hemorrhage. Many of the included studies were of low methodological quality and participant numbers were small. Bleeding outcomes were reported in 32 studies; 7 reported significantly reduced transfusion use following a variety of clinical interventions, but this was not accompanied by improved survival. Minimal information was found on traumatic coagulopathy across the identified RCTs. Overall survival was improved in only three RCTs: two small studies and a large study evaluating the use of tranexamic acid. Conclusions Despite 35 RCTs there has been little improvement in outcomes over the last few decades. No clear correlation has been demonstrated between transfusion requirements and mortality. The global trauma community should consider a coordinated and strategic approach to conduct well designed studies with pragmatic endpoints. PMID:21392371

    It is unclear whether post-traumatic stress disorder symptoms and reports of traumatic childhood experiences decline during substance withdrawal. A convenience sample of 34 inpatients of the Psychiatric University Clinics in Basel was recruited and general psychopathological and trauma-related symptoms were assessed with the Brief Symptom Checklist, Post-Traumatic Stress Diagnostic Scale, and Childhood Trauma Questionnaire in the 1st and 3rd week of substance use treatment. The average age of the sample was 41.9 (SD = 9.1) years, and 26.5% were female. Hyperarousal (Mt1 = 4.51 versus Mt2 = 3.61; z = -2.38, p = .017) and avoidance symptoms (Mt1 = 6.24 versus Mt2 = 4.27; z = -2.59, p = .010) declined significantly, but re-experiencing symptoms (Mt1 = 4.00 versus Mt2 = 3.45; z = -.50, p = .617) did not. Post-traumatic stress disorder assessment, according to the Diagnostic and Statistical Manual of Mental Disorders-4th edition criteria, remained constant for 28 of 34 patients. Likewise, self-reported childhood trauma experiences decreased, yet the number of elevated subscale scores remained stable. Post-traumatic stress disorder symptoms are not adequately treated by substance withdrawal alone. Trauma-specific diagnostics can be initiated with sufficient quality as early as the first week of withdrawal treatment. PMID:26670631

    In 1985 Andreasen and Andreasen published a paper on the diagnosis of luxation injuries and outlined the importance of standardized clinical, radiographic, and photographic techniques. Now 30 years later, these recommendations remain current in the International Association of Dental Traumatology (IADT) guidelines for the management of dental trauma and describe circumstances surrounding the time of injury, the extent of trauma (e.g., type of luxation injury), healing potential (e.g., stage of root development) as well as information concerning subsequent treatment. The purpose of this review was to include findings for other types of trauma and to discuss more recent studies that augment and/or improve on the original findings from 30 years ago. The present review discusses the use of a standardized clinical registration (pulpal sensibility testing, laser Doppler flowmetry, mobility testing), radiographic survey, and photographic registration of the traumatized patient. Moreover, the value of digital radiographs and recent developments in computer tomography with respect to possible enhancement of the trauma diagnosis are discussed. PMID:26058528

This injury has been noted through history, mentioned as early as Ancient Egypt, and prevalent in the 19 century, the time before using the car, until today. The mechanism of injury is described, as well as treatment, and news in view of the frequency of injuries in different parts of the world and the impact of socio-cultural, economic, ethnic and geographic factors. Impacts of traffic laws, automobile production and automobile seats that would indicate the possibility of prevention as a result of a whiplash injury of the cervical spine are also presented.

    Objective Most whiplash patients eventually recover, although some are left with ongoing pain and impairment. Why some develop long-term symptoms after whiplash, whereas others do not, is largely unknown. One explanation blames the cultural expectations of the population wherein the injury occurred, engendering the moniker whiplash culture. The purpose of this review was to locate and discuss studies that were used as a basis for developing the whiplash culture concept and to evaluate its plausibility. Methods The PubMed database was searched using combinations of the terms whiplash culture, whiplash OR WAD, and chronic OR late OR long term. Search dates spanned from 1950 to June 2008. Filters were set to only retrieve English-language citations. Articles that dealt with the whiplash culture were selected and examined to determine which studies had been used to create the concept. Results Nineteen articles discussed the cultural aspects of whiplash and were explored to determine which were used as a basis for the whiplash culture. Eight studies were found that met this final criterion. Conclusion There are many unanswered questions about the basis of chronic whiplash, and the notion of a whiplash culture is controversial. Chronic whiplash symptoms are surely not caused entirely by cultural issues, yet they are probably not entirely physical. Presumably, a tissue injury component exists in most chronic whiplash-associated disorder victims that becomes aggravated in those who are susceptible to biopsychosocial factors. As with many other controversial health care topics, the answer to the debate probably lies somewhere in the middle. PMID:19703667

    Background: Acute kidney injury (AKI) is a common problem in critically ill patients and is independently associated with increased morbidity and mortality. Recently, serum cystatin C has been shown to be superior to creatinine in early detection of renal function impairment. We compared estimated GFR based on serum cystatin C with estimated GFR based on serum creatinine for early detection of renal dysfunction according to the RIFLE criteria. Methods: During 9 months, three hundred post trauma patients that were referred to the intensive care unit of a referral trauma hospital were recruited. Serum creatinine and serum cystatin C were measured and the estimated GFR within 24 hours of ICU admission was calculated. The primary outcome was the incidence of AKI according to the RIFLE criteria within 2nd to 7th day of admission. Results: During the first week of ICU admission, 21% of patients experienced AKI. After adjusting for major confounders, only the patients with first day’s serum cystatin level higher than 0.78 mg/l were at higher risk of first week AKI (OR=6.14, 95% CI: 2.5-14.7, P<0.001). First day’s serum cystatin C and injury severity score were the major risk factors for ICU mortality (OR=3.54, 95% CI: 1.7-7.4, P=0.001) and (OR=4.6, 95% CI: 1.5-14, P=0.007), respectively. Conclusion: Within 24 hours after admission in ICU due to multiple trauma, high serum cystatin C level may have prognostic value in predicting early AKI and mortality during ICU admission. However, such correlation was not seen neither with creatinine nor cystatin C based GFR. PMID:26538776

    2008-01-01

    Background Persistent whiplash associated disorders (WAD) have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM), conjunct motion, joint position error and ROM-variability. Methods Participants (n = 173) were recruited to three groups: 59 patients with persistent WAD, 57 patients with chronic non-traumatic neck pain and 57 asymptomatic volunteers. A 3D motion tracking system (Fastrak) was used to record maximal range of motion in the three cardinal planes of the cervical spine (sagittal, frontal and horizontal), and concurrent motion in the two associated cardinal planes relative to each primary plane were used to express conjunct motion. Joint position error was registered as the difference in head positions before and after cervical rotations. Results Reduced conjunct motion was found for WAD and chronic neck pain patients compared to asymptomatic subjects. This was most evident during cervical rotation. Reduced conjunct motion was not explained by current pain or by range of motion in the primary plane. Total conjunct motion during primary rotation was 13.9° (95% CI; 12.2–15.6) for the WAD group, 17.9° (95% CI; 16.1–19.6) for the chronic neck pain group and 25.9° (95% CI; 23.7–28.1) for the asymptomatic group. As expected, maximal cervical range of motion was significantly reduced among the WAD patients compared to both control groups. No group differences were found in maximal ROM-variability or joint position error. Conclusion Altered movement patterns in the cervical spine were found for both pain groups, indicating changes in motor control strategies. The changes were not related to a history of neck trauma, nor

    A theoretical framework referred to as a 4-D model has been described for classifying posttraumatic stress symptoms into those potentially occurring within normal waking consciousness (NWC) versus those thought to intrinsically exemplify dissociative experiences, specifically, trauma-related altered states of consciousness (TRASC). As a further test of this theoretical distinction, this prospective study evaluated whether TRASC and NWC forms of distress incrementally and prospectively predicted functional impairment at 6 and 12 weeks following presentation at hospital emergency departments in the acute aftermath of traumatic events in 180 persons. Establishing the clinical significance of both TRASC and NWC-distress symptoms, we found that 6-week markers of TRASC and NWC-distress independently predicted 12-week self-reported levels of social and occupational impairment. We also observed broad support for various predictions of the 4-D model except that, in contrast with hypotheses, childhood trauma history was generally more strongly correlated with symptoms of NWC-distress than with TRASC. Future research directions are discussed. PMID:26378486

    Objective Oxidative damage is a critical role which involves hearing loss induced by impulse noise. That exogenous antioxidant agents reduce noise induced hearing loss (NIHL) has been well demonstrated in both animal studies and clinical practices. Choosing a stronger and more effective antioxidant is very important for treatment of NIHL. Vitamin E, α-lipoic acid, and radix astragali are the most commonly used anti-oxidants for cochlear oxidative damage from acoustic trauma. In this study, the protective effects of radix astragali, α-lipoic acid, and vitamin E on acute acoustic trauma are investigated. Methods Guinea pigs in the experimental groups were intragastrically administered vitamin E, α-lipoic acid, and radix astragali. Auditory thresholds were assessed by sound-evoked auditory brainstem response (ABR) at click and tone bursts of 8, 16 and 32 kHz, 24 hours before and 72 hours after exposure to impulse noise. Cochlear malondialdehyde (MDA) concentrations were detected. Hair cell damage was analyzed by scanning electron microscopy. Results Vitamin E, α-lipoic acid, and radix astragali significantly reduced ABR deficits, reduced hair cell damage, and decreased the concentrations of MDA. α-lipoic acid and radix astragali were better than vitamin E, and there were no significant differences between α-lipoic acid and radix astragali. Conclusions α-lipoic acid or radix astragali are recommended for treatment of NIHL. PMID:24179406

    1. The whiplash injury of the cervical spine is a typical, but not very often observed injury of occupants of automotive vehicles involved in moderate collisions. 2. There still exist great uncertainties in the elaboration of expertises concerning the minor whiplash injury, so that the great part of the disturbances cannot be objectivated under a clinical point of view. And on the other hand, serious whiplash injuries often are superposed or veiled by secondary injuries. 3. Thus, the aim of the present paper was to point out injury mechanisms, to give a rough scaling of the whiplash severity under biomechanical aspects and finally to set these injury mechanisms in correlation to the following criteria of accident: a) vehicle velocity change (energy equivalent speed--EES); b) deformation of vehicles on the impact-exposed structure; c) loading of occupants by acceleration or deceleration. 4. The tolerance limit of the cervical spine generally decreases to a lower limit, if the cervical spine is changed in a pathological way, e.g. by preexisting diseases. 5. It is evident and important, that the difficult work of giving an expert's opinion on this field must be performed in an interdisciplinary collaboration of engineers for collision-analysis and physicians experienced in accident-traumatology.

    Lung protective ventilation strategies for patients with acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are well documented, and many medical centers fail to apply these strategies in ALI/ARDS. The objective of this study was to determine if we apply these strategies in trauma patients at risk for ALI/ARDS. We undertook a retrospective review of trauma patients mechanically ventilated for > or = 4 days with an ICD-9 for traumatic pneumothorax, hemothorax, lung contusion, and/or fractured ribs admitted from May 1, 1999 through April 30, 2000 (Group 1), the pre-ARDS Network study, and from May 1, 2003 through April 30, 2004 (Group 2), the post-ARDS Network study. Tidal volume (VT)/kg admission body weight, VT/kg ideal body weight (IBW), and plateau and peak pressures were analyzed with respect to mortality. VT/Kg admission body weight and IBW were significantly reduced when comparing Group 1 with Group 2 (9.27 to 8.03 and 11.67 to 10.04, respectively). VT/kg IBW was greater (P < 0.01) for patients who died in Group 1 (13.81) compared with patients who lived (10.29) or died (9.89) in Group 2. Peak and plateau pressures were greater (P < 0.01) in patients who died in Group 1 than patients who lived or died in Group 2. A strict ARDS Network ventilation strategy (VT < 6 mL/kg) is not followed, rather a low plateau/peak pressure strategy is used, which is a form of lung protective ventilation. PMID:17439026

    Acute vascular injuries are the second most common cause of fatalities in patients with multiple traumatic injuries; thus, prompt identification and management is essential for patient survival. Over the past few years, multidetector CT (MDCT) using dual-phase scanning protocol has become the imaging modality of choice in high-energy deceleration traumas. The objective of this article was to review the role of dual-phase MDCT in the identification and management of acute vascular injuries, particularly in the chest and abdomen following multiple traumatic injuries. In addition, this article will provide examples of MDCT features of acute vascular injuries with correlative surgical and interventional findings. PMID:26882960

    A growing literature suggests the clinical importance of acute stress disorder (ASD) symptoms in youth following potentially traumatic events. A multisite sample of English and Spanish speaking children and adolescents (N=479) between the ages of 8 to 17, along with their caregivers completed interviews and self-report questionnaires between 2 days and one month following the event. The results indicate that children with greater total acute stress symptoms reported greater depressive (r = .41, p < .01), and anxiety symptoms (r = .53, p < .01). Examining specific acute stress subscales, re-experiencing was correlated with anxiety (r = .47, p < .01) and arousal was correlated with depression (r = .50, p < .01) and anxiety (r = .55, p < .01). Age was inversely associated with total acute stress symptoms (r = -.24, p < .01), re-experiencing (r = -.17, p < .01), avoidance (r = -.27, p < .01), and arousal (r = -.19, p < .01) and gender was related to total anxiety symptoms (Spearman's rho = .17, p < .01). The current study supports the importance of screening acute stress symptoms and other mental health outcomes following a potentially traumatic event in children and adolescents. Early screening may enable clinicians to identify and acutely intervene to support children's psychological and physical recovery. PMID:24337685

    Background Older trauma injury patients had improved recovery after we implemented routine geriatric consultation for patients ≥ age 65 at a level-1 academic trauma center. The intervention aimed to improve quality of geriatric care. However, the specific care processes that improved are unknown. Study Design Prospective observation comparing medical care after (December 2007-November 2009) versus before (December 2006-November 2007) implementation of the geriatric consult-based intervention. To measure quality-of-care (QOC) we used 33 previously-validated care-process quality indicators (QIs) from the Assessing the Care of Vulnerable Elders (ACOVE) study, measured by review of medical records for 76 Geriatric Consult [GC] versus 71 control group patients. As pre-specified subgroup analyses, we aggregated QIs by type: geriatric (e.g., delirium screening) versus non-geriatric condition-based care (e.g., thrombosis prophylaxis) and compared QI scores by type of care. Last, we aggregated QI scores into overall, geriatric, and non-geriatric QOC scores for each patient (# QIs passed/# QIs eligible), and compared patient-level QOC for the GC versus control group, adjusting for age, gender, ethnicity, comorbidity, and injury severity. Results 63% of the GC versus 11% of the control group patients received a geriatric consultation. We evaluated 2505 QIs overall (1664 geriatric-type and 841 non-geriatric QIs). In general, fewer geriatric-type QIs were passed than non-geriatric QIs (71% vs 81%, p<.001). We provided better overall-QOC to the GC (77%) than control group patients (73%, p<.05). However, the difference was not statistically significant after multivariable adjustment (p=.08). We improved geriatric-QOC for the GC (74%) compared to the control group (68%, p<.01), a difference that was significant after multivariable adjustment (p=.01). Conclusion Geriatricians and surgeons can collaboratively improve geriatric QOC for older trauma patients. PMID:25840534

    OBJECTIVE: To evaluate the effects of physiotherapeutic respiratory maneuvers on cerebral and cardiovascular hemodynamics and blood gas variables. METHOD: A descriptive, longitudinal, prospective, nonrandomized clinical trial that included 20 critical patients with severe craniocerebral trauma who were receiving mechanical ventilation and who were admitted to the intensive care unit. Each patient was subjected to the physiotherapeutic maneuvers of vibrocompression and increased manual expiratory flow (5 minutes on each hemithorax), along with subsequent airway suctioning with prior instillation of saline solution, hyperinflation and hyperoxygenation. Variables related to cardiovascular and cerebral hemodynamics and blood gas variables were recorded after each vibrocompression, increased manual expiratory flow and airway suctioning maneuver and 10 minutes after the end of airway suctioning. RESULTS: The hemodynamic and blood gas variables were maintained during vibrocompression and increased manual expiratory flow maneuvers; however, there were increases in mean arterial pressure, intracranial pressure, heart rate, pulmonary arterial pressure and pulmonary capillary pressure during airway suctioning. All of the values returned to baseline 10 minutes after the end of airway suctioning. CONCLUSION: Respiratory physiotherapy can be safely performed on patients with severe craniocerebral trauma. Additional caution must be taken when performing airway suctioning because this technique alters cerebral and cardiovascular hemodynamics, even in sedated and paralyzed patients. PMID:24141836

    The objective of this study was to determine whether clinically significant ocular trauma can be induced by a survivable isolated primary blast using a live animal model. Both eyes of 18 Dutch Belted rabbits were exposed to various survivable low-level blast overpressures in a large-scale shock tube simulating a primary blast similar to an improvised explosive device. Eyes of the blast-exposed rabbits (as well as five control rabbits) were thoroughly examined before and after blast to detect changes. Clinically significant changes in corneal thickness arose immediately after blast and were sustained through 48 h, suggesting possible disruption of endothelial function. Retinal thickness (RT) increased with increasing specific impulse immediately after exposure. Intraocular pressure (IOP) was inversely correlated with the specific impulse of the blast wave. These findings clearly indicate that survivable primary blast causes ocular injuries with likely visual functional sequelae of clinical and military relevance. PMID:26393900

    Background: We studied whether methylene blue (MB) treatment blunts chest trauma-induced lung injury in rats. Material and Methods: Forty male Sprague-Dawley rats, 200-300g, were used. The rats were divided into five groups (n=8): control, early contusion (EC), early contusion + methylene blue (2 mg/kg, EC+MB), late contusion (LC), and late contusion + methylene blue (2 mg/kg, LC+MB). Results: Histopathological analysis showed increased hemorrhage, alveolar wall thickness, edema, and inflammatory cell infiltrates in the EC and LC rats, which decreased upon MB treatment. Immunohistochemical studies revealed that MB reduced activation of inducible nitric oxide synthase (iNOS) and the number of active terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-positive cells. A significant increase was observed in the malondialdehyde (MDA) and nitric oxide (NO) levels in the EC group compared to the control group (p<0.05). In addition, a significant decrease was reported in the glutathione (GSH), superoxide dismutase (SOD), and glutathione peroxidase (GPx) levels (p<0.01), but no significant difference was observed in the catalase (CAT) levels among the groups. The MDA level was significantly higher in the LC group compared to the control group, whereas the GSH level was significantly lower compared to the control group. The NO level in the EC+MB group was significantly lower when compared to the NO level in the EC group (p<0.05). Conclusion: The present study provides evidence that MB might serve as a therapeutic treatment for blunt chest trauma. PMID:25125953

    Objective Since P188 poloxamer is effective in promoting cell survival in models of acute trauma the objectives were to understand the mechanism of its action focusing on GSK3 activation, IL-6 and p38 signaling. Design Sixteen normal human tali were impacted using 4mm diameter indenter with an impulse of 1Ns. 8mm cartilage plugs containing the 4mm impacted core and 4mm adjacent non-impacted ring were removed and cultured with or without P188. Cell lysates were analyzed using Western blots with antibodies against total and phosphorylated ERK, JNK, p38, ATF-2, GSK3, Stat1 and Stat3. Additional tests were performed with the p38 inhibitor (p38i) SB203580. Results Studied pathways were activated after impaction with the peak of activity at 1hour. P188 completely attenuated phosphorylation of Stat1 and ATF-2 and inhibited p38, Stat3, JNK, ERK, and GSK3. The p38i partially offset phosphorylation of Stat3, GSK3, and ERK suggesting a role of p38 in these three pathways. Additionally, the p38i improved cell survival (p=0.053) and reduced apoptosis (by about 20%, p=0.046, vs almost 40% by P188) thus confirming that P188 acts (at least in part) via p38 pathway. Conclusion Our results report a novel mechanism through which P188 exerts its protective effects on cartilage in the model of acute injury. In addition to its effect on cellular membrane, P188 affects stress-related p38 signaling, apoptosis-related GSK3, and inflammation-related IL-6 signaling. Taken together these findings suggest that P188 alone or in combination with pro-anabolic agents may have a therapeutic potential in preventing progressive cartilage degeneration and the development of post-traumatic osteoarthritis.

    Increased activities of certain biochemical enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST], lactate dehydrogenase [LDH], alkaline phosphatase [ALP]) have been associated with blunt liver injury in many species. To evaluate changes in plasma hepatic biochemical parameters in acute avian liver disease caused by trauma and to compare biochemical changes with histologic lesions in hepatic parenchyma, 30 healthy fasted Indian ring-necked parakeets (Psittacula krameri manillensis) were divided into 2 groups, and traumatic liver injury was caused by endoscopic liver biopsy (group 1) or by liver biopsy and crushing injury to the hepatic parenchyma with endoscopic forceps (group 2) in anesthetized birds. Blood samples were collected at baseline and at 12, 24, 36, 48, 60, 72, 84, 96, 108, and 120 hours in alternate groups to compare analyte values after injury with those at baseline. Results showed consistently decreased plasma ALP activity (excluding 1 time point) throughout the study, which was thought to be associated with isoflurane administration. Plasma glutamate dehydrogenase activity initially increased but rapidly declined thereafter and was attributed to acute focal hepatocellular injury. In both groups, increases in plasma AST, ALT, and LDH activities was most likely caused by muscle injury because creatine kinase activity was concurrently increased. Compared with baseline values, bile acid concentration and y-glutamyl transferase activity were not affected by liver biopsy or crush injury. Plasma sorbitol dehydrogenase activity was the most specific indicator of liver injury in both groups. Histologic changes correlated poorly with biochemical results, possibly because the small area of hepatic parenchyma that was damaged did not affect enzyme values substantially. PMID:22872978

    In a recently published report from the Academy of Medical Royal Colleges, around 20% of clinical practice which encompasses blood science investigations is considered wasteful. Blood tests including liver function tests (LFTs), C-reactive protein (CRP), coagulation screens, and international normalising ratios (INR) are frequently requested for patients who undergo emergency hospital admission. The paucity of guidance available for blood requesting in acute trauma and orthopaedic admissions can lead to inappropriate requesting practices and over investigation. Acute admissions over a period of one month were audited retrospectively for the frequency and clinical indications of requests for LFTs, coagulation screens/INR, and CRP. The total number of blood tests requested for the duration of the patient's admission was recorded. Initial auditing of 216 admissions in January 2014 demonstrated a striking amount of over-investigation. Clinical guidelines were developed with multidisciplinary expert input and implemented within the department. Re-audit of 233 admissions was carried out in September 2014. Total no. of LFTs requested: January 895, September 336 (-62.5%); coagulation screens/INR requested: January 307, September 210 (-31.6%); CRPs requested: January 894, September 317 (-64.5%). No. of blood requests per patient: January (M=4.81, SD 4.75), September (M=3.60, SD=4.70). Approximate combined total cost of LFT, coagulation/INR, CRP in January £2674.14 and September £1236.19 (-£1437.95, -53.77%). A large decrease was observed in admission requesting and subsequent monitoring (p<0.01) following the implementation. This both significantly reduced cost and venepuncture rates. PMID:26696248

    In science findings which cannot be extrapolated to other settings are of little value. Recruitment methods vary widely across chronic whiplash studies, but it remains unclear whether this generates recruitment bias. The present study aimed to examine whether the recruitment method accounts for differences in health status, social support, and personality traits in patients with chronic whiplash-associated disorders (WAD). Two different recruitment methods were compared: recruiting patients through a local whiplash patient support group (group 1) and local hospital emergency department (group 2). The participants (n=118) filled in a set of questionnaires: the Neck Disability Index, Medical Outcome Study Short-Form General Health Survey, Anamnestic Comparative Self-Assessment measure of overall well-being, Symptom Checklist-90, Dutch Personality Questionnaire, and the Social Support List. The recruitment method (either through the local emergency department or patient support group) accounted for the differences in insufficiency, somatization, disability, quality of life, self-satisfaction, and dominance (all p values <.01). The recruitment methods generated chronic WAD patients comparable for psychoneurotism, social support, self-sufficiency, (social) inadequacy, rigidity, and resentment (p>.01). The recruitment of chronic WAD patients solely through patient support groups generates bias with respect to the various aspects of health status and personality, but not social support. In order to enhance the external validity of study findings, chronic WAD studies should combine a variety of recruitment procedures. PMID:21853277

    The most common consequences of acute acoustic trauma (AAT) are hearing loss at frequencies above 3 kHz and tinnitus. In this study, we have used functional Magnetic Resonance Imaging (fMRI) to visualize neuronal activation patterns in military adults with AAT and various tinnitus sequelae during an auditory "oddball" attention task. AAT subjects displayed overactivities principally during reflex of target sound detection, in sensorimotor areas and in emotion-related areas such as the insula, anterior cingulate and prefrontal cortex, in premotor area, in cross-modal sensory associative areas, and, interestingly, in a region of the Rolandic operculum that has recently been shown to be involved in tympanic movements due to air pressure. We propose further investigations of this brain area and fine middle ear investigations, because our results might suggest a model in which AAT tinnitus may arise as a proprioceptive illusion caused by abnormal excitability of middle-ear muscle spindles possibly link with the acoustic reflex and associated with emotional and sensorimotor disturbances.

  6. Management of the open abdomen: clinical recommendations for the trauma/acute care surgeon and general surgeon.

    Fernández, Luis G

    2016-09-01

    Traditionally, the surgical approach to managing abdominal injuries was to assess the extent of trauma, repair any damage and close the abdomen in one definitive procedure rather than leave the abdomen open. With advances in medicine, damage control surgery using temporary abdominal closure methods is being used to manage the open abdomen (OA) when closure is not possible. Although OA management is often observed in traumatic injuries, the extension of damage control surgery concepts, in conjunction with OA, for the management of the septic patient requires that the general surgeon who is faced with these challenges has a comprehensive knowledge of this complex subject. The purpose of this article is to provide guidance to the acute care and general surgeon on the use of OA negative pressure therapy (OA-NPT; ABTHERA™ Open Abdomen Negative Pressure Therapy System, KCI, an ACELITY Company, San Antonio, TX) for OA management. A literature review of published evidence, clinical recommendations on managing the OA and a case study demonstrating OA management using OA-NPT have been included. PMID:27547961

  7. The axon as a physical structure in health and acute trauma.

    PubMed

    Kirkcaldie, Matthew T K; Collins, Jessica M

    2016-10-01

    The physical structure of neurons - dendrites converging on the soma, with an axon conveying activity to distant locations - is uniquely tied to their function. To perform their role, axons need to maintain structural precision in the soft, gelatinous environment of the central nervous system and the dynamic, flexible paths of nerves in the periphery. This requires close mechanical coupling between axons and the surrounding tissue, as well as an elastic, robust axoplasm resistant to pinching and flattening, and capable of sustaining transport despite physical distortion. These mechanical properties arise primarily from the properties of the internal cytoskeleton, coupled to the axonal membrane and the extracellular matrix. In particular, the two large constituents of the internal cytoskeleton, microtubules and neurofilaments, are braced against each other and flexibly interlinked by specialised proteins. Recent evidence suggests that the primary function of neurofilament sidearms is to structure the axoplasm into a linearly organised, elastic gel. This provides support and structure to the contents of axons in peripheral nerves subject to bending, protecting the relatively brittle microtubule bundles and maintaining them as transport conduits. Furthermore, a substantial proportion of axons are myelinated, and this thick jacket of membrane wrappings alters the form, function and internal composition of the axons to which it is applied. Together these structures determine the physical properties and integrity of neural tissue, both under conditions of normal movement, and in response to physical trauma. The effects of traumatic injury are directly dependent on the physical properties of neural tissue, especially axons, and because of axons' extreme structural specialisation, post-traumatic effects are usually characterised by particular modes of axonal damage. The physical realities of axons in neural tissue are integral to both normal function and their response to

    Background The proper timing for surgery in patients with acute spinal cord injury is controversial. This study was conducted to detect if there is an advantage in early (within the first 4 hours after trauma) compared to late (between 4 and 24 hours after trauma) surgery on neurological outcome. Methods In this single institution prospective cohort study, data were analyzed from 51 spinal cord injured patients with an average age of 43.4 (±19.2) years. The influence of early (29 patients within the first 4 hours) as opposed to late (22 patients between 4 and 24 hours) decompression was evaluated by comparing data for neurological outcome. Patients of the study collectively suffered acute spinal fractures from C2 to L3 (cervical 39.2%, thoracic 29.4%, and lumbal 21.6%) or nonosseous lesions (9.8%). American Spinal Injury Association (ASIA) Impairment Scale (AIS) grades were assessed at time of admission and 6 months after trauma or longer depending on the time of release. Surgical treatment included early stabilization and decompression within 24 hours. Results No significant difference between improved neurological function, measured with the AIS, and an early or late surgery time can be seen (P=0.402). Furthermore, binary logistic regression shows no significant difference between sex or age, and AIS improvement as possible confounders. Conclusion In our study, all patients with spinal cord injury were treated with spine stabilization and decompression within the first 24 hours after trauma. Surgical decompression within the first 4 hours after trauma was not associated with improved neurological outcome compared to treatment between 4 and 24 hours. In a clinical context, this indicates that there is a time frame of at least 1 day in which optimal care is possible. PMID:27621643

    A 13-year-old boy with a history of bicycle handlebar injury to the left side of his abdomen was brought to the Emergency Department of our center. On admission, his vital signs were stable and abdominal examination revealed ecchymosis and tenderness of the injured areas. Mild to moderate free fluid and two small foci of free air in the anterior aspect of the abdomen, in favor of pneumoperitoneum, were detected in abdominopelvic sonography and CT-scan, respectively. In less than 6 hours, the patient developed generalized peritonitis. Therefore, exploratory laparotomy was promptly performed, which revealed appendiceal transection and rupture of the small bowel mesentery. Appendectomy and small bowel mesoplasty were done, with pathological diagnosis of acute appendicitis and periappendicitis. After surgery, the patient had a non-complicated hospital course. This rare case highlights the significance of the early management of appendiceal traumatic injuries in order to prevent further complicated events, especially in patients who are much more exposed to this risk due to their traumatic background.

    Intrusive memories are a hallmark symptom of posttraumatic stress disorder (PTSD). They reflect excessive and uncontrolled retrieval of the traumatic memory. Acute elevations of cortisol are known to impair the retrieval of already stored memory information. Thus, continuous cortisol administration might help in reducing intrusive memories in PTSD. Strong perceptual priming for neutral stimuli associated with a "traumatic" context has been shown to be one important learning mechanism that leads to intrusive memories. However, the memory modulating effects of cortisol have only been shown for explicit declarative memory processes. Thus, in our double blind, placebo controlled study we aimed to investigate whether cortisol influences perceptual priming of neutral stimuli that appeared in a "traumatic" context. Two groups of healthy volunteers (N = 160) watched either neutral or "traumatic" picture stories on a computer screen. Neutral objects were presented in between the pictures. Memory for these neutral objects was tested after 24 hours with a perceptual priming task and an explicit memory task. Prior to memory testing half of the participants in each group received 25 mg of cortisol, the other half received placebo. In the placebo group participants in the "traumatic" stories condition showed more perceptual priming for the neutral objects than participants in the neutral stories condition, indicating a strong perceptual priming effect for neutral stimuli presented in a "traumatic" context. In the cortisol group this effect was not present: Participants in the neutral stories and participants in the "traumatic" stories condition in the cortisol group showed comparable priming effects for the neutral objects. Our findings show that cortisol inhibits perceptual priming for neutral stimuli that appeared in a "traumatic" context. These findings indicate that cortisol influences PTSD-relevant memory processes and thus further support the idea that administration

    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

    Abstract Concussive brain injury (CBI) accounts for approximately 75% of all brain-injured people in the United States each year and is particularly prevalent in contact sports. Concussion is the mildest form of diffuse traumatic brain injury (TBI) and results in transient cognitive dysfunction, the neuropathologic basis for which is traumatic axonal injury (TAI). To evaluate the structural and functional changes associated with concussion-induced cognitive deficits, adult mice were subjected to an impact on the intact skull over the midline suture that resulted in a brief apneic period and loss of the righting reflex. Closed head injury also resulted in an increase in the wet weight:dry weight ratio in the cortex suggestive of edema in the first 24 h, and the appearance of Fluoro-Jade-B-labeled degenerating neurons in the cortex and dentate gyrus of the hippocampus within the first 3 days post-injury. Compared to sham-injured mice, brain-injured mice exhibited significant deficits in spatial acquisition and working memory as measured using the Morris water maze over the first 3 days (p<0.001), but not after the fourth day post-injury. At 1 and 3 days post-injury, intra-axonal accumulation of amyloid precursor protein in the corpus callosum and cingulum was accompanied by neurofilament dephosphorylation, impaired transport of Fluoro-Gold and synaptophysin, and deficits in axonal conductance. Importantly, deficits in retrograde transport and in action potential of myelinated axons continued to be observed until 14 days post-injury, at which time axonal degeneration was apparent. These data suggest that despite recovery from acute cognitive deficits, concussive brain trauma leads to axonal degeneration and a sustained perturbation of axonal function. PMID:21299360

    Study Design This research utilized a cross-sectional design with control group inclusion. Objectives Preliminary evidence suggests that a portion of the patient population with chronic whiplash may have sustained spinal cord damage. Our hypothesis is that in some cases of chronic whiplash-associated disorders (WAD), observed muscle weakness in the legs will be associated with local signs of a partial spinal cord injury of the cervical spine. Setting University based laboratory in Chicago, IL, USA. Methods Five participants with chronic WAD were compared with five gender/age/height/weight/body mass index (BMI) control participants. For a secondary investigation, the chronic WAD group was compared with five unmatched participants with motor incomplete spinal cord injury (iSCI). Spinal cord motor tract integrity was assessed using magnetization transfer imaging. Muscle fat infiltration (MFI) was quantified using fat/water separation magnetic resonance imaging. Central volitional muscle activation of the plantarflexors was assessed using a burst superimposition technique. Results We found reduced spinal cord motor tract integrity, increased MFI of the neck and lower extremity muscles and significantly impaired voluntary plantarflexor muscle activation in five participants with chronic WAD. The lower extremity structural changes and volitional weakness in chronic WAD were comparable to participants with iSCI. Conclusion The results support the position that a subset of the chronic whiplash population may have sustained partial damage to the spinal cord.

    Tissue damage or pathological alterations are not detectable in the majority of people with whiplash associated disorders (WAD). Widespread hyperalgisa, morphological muscle changes and psychological distress are common features of WAD. However little is known about the presence of inflammation and its association with symptom persistence or the clinical presentation of WAD. This study aimed to prospectively investigate changes in serum inflammatory biomarker levels from the acute (<3 weeks) to chronic (>3 months) stages of whiplash injury. It also aimed to determine relationships between biomarker levels and hyperalgesia, fatty muscle infiltrates of the cervical extensors identified on MRI and psychological factors. 40 volunteers with acute WAD and 18 healthy controls participated. Participants with WAD were classified at 3 months as recovered/mild disability or having moderate/severe disability using the Neck Disability Index. At baseline both WAD groups showed elevated serum levels of CRP but by 3 months levels remained elevated only in the moderate/severe group. The recovered/mild disability WAD group had higher levels of TNF-α at both time points than both the moderate/severe WAD group and healthy controls. There were no differences found in serum IL-1β. Moderate relationships were found between hyperalgesia and CRP at both time points and between hyperalgesia and IL-1β 3 months post injury. There was a moderate negative correlation between TNF-α and amount of fatty muscle infiltrate and pain intensity at 3 months. Only a weak relationship was found between CRP and pain catastrophising and no relationship between biomarker levels and posttraumatic stress symptoms. The results of the study indicate that inflammatory biomarkers may play a role in outcomes following whiplash injury as well as being associated with hyperalgesia and fatty muscle infiltrate in the cervical extensors.

  16. Whiplash evokes descending muscle recruitment and sympathetic responses characteristic of startle

    Whiplash injuries are the most common injuries following rear-end collisions. During a rear-end collision, the human muscle response consists of both a postural and a startle response that may exacerbate injury. However, most previous studies only assessed the presence of startle using data collected from the neck muscles and head/neck kinematics. The startle response also evokes a descending pattern of muscle recruitment and changes in autonomic activity. Here we examined the recruitment of axial and appendicular muscles along with autonomic responses to confirm whether these other features of a startle response were present during the first exposure to a whiplash perturbation. Ten subjects experienced a single whiplash perturbation while recording electromyography, electrocardiogram, and electrodermal responses. All subjects exhibited a descending pattern of muscle recruitment, and increasing heart rate and electrodermal responses following the collision. Our results provide further support that the startle response is a component of the response to whiplash collisions. PMID:24932015

    Whiplash injuries from motor vehicle accidents are very common. The usual presentation and course of this condition normally results in resolution of symptoms within a few weeks. Brachial plexus traction injuries without any bone or joint lesion of the cervical spine have been reported before. We report a case where a gentleman was involved in a rear end vehicle collision, sustained a whiplash injury and was later found to have a long thoracic nerve palsy and spinal accessory nerve palsy. Although isolated injuries of both nerves following a whiplash injury have been reported, combined injury of the two nerves following a whiplash injury is very uncommon and is being reported for the first time.

    The tongue plays a fundamental role in several bodily functions; in the case of a dysfunction, an exhaustive knowledge of manual techniques to treat the tongue is useful in order to help patients on their path toward recovery. A 30-year-old male patient with a recent history of whiplash, with increasing cervical pain during swallowing and reduced ability to open the mouth, was treated with osteopathic techniques addressed to the tongue. The osteopathic techniques led to a disappearance of pain and the complete recovery of the normal functions of the tongue, such as swallowing and mouth opening. The manual osteopathic approach consists of applying a low load, in order to produce a long-lasting stretching of the myofascial complex, with the aim of restoring the optimal length of this continuum, decreasing pain, and improving functionality. According to the authors’ knowledge, this is the first article reporting a case of resolution of a post whiplash disorder through osteopathic treatment of the tongue. PMID:27462180

    The subject of this case report was a 56-year-old woman who sustained a whiplash-associated disorder as a result of a motor vehicle accident. Within a few hours after the accident, she developed a headache, which became chronic, creating disability and hindering the quality of her life. In the following year, a variety of diagnostic tests, medications, and physical therapy were unsuccessful in determining the cause of her complaints or in relieving them. After this year, she expressed anger, frustration, and a reluctance to undergo additional physical therapy. By listening to her explain how she coped with her problem and observing that she lacked the ability to reduce her cervical lordosis, the therapist developed and implemented a home program of supine cervical traction and exercise. After 30 days of treatment, she was able to reduce and control her headache. This treatment and the approach used to develop the treatment may benefit other patients who have whiplash-associated chronic headache. PMID:9105344

    This study aimed to test the dimensional structure of acute stress disorder (ASD). Latent profile analysis was conducted on scores from the Acute Stress Disorder Scale (Bryant, Moulds, & Guthrie, 2000) using a large sample of female victims of sexual trauma. Four distinct classes were found. Two of the classes represented high and low levels of ASD, and the high ASD class was associated with a high probability of subsequent posttraumatic stress disorder (PTSD). There were 2 intermediate classes that were differentiated by the number of arousal symptoms, and the class with high levels of arousal symptoms had a higher risk of PTSD. The results suggested that ASD is best described by qualitatively and quantitatively differing subgroups in this sample, whereas previous research has assumed ASD to be dimensional. This may explain the limited success of using ASD to predict subsequent PTSD. (PsycINFO Database Record (c) 2014 APA, all rights reserved). PMID:24978131

    Activation of Fas signaling is a potentially important pathophysiological mechanism in the development of septic acute lung injury (ALI). However, so far the optimal targets within this signaling cascade remain elusive. Thus, we tested the hypothesis that in vivo gene silencing of Fas, Fas-associated via death domain (FADD), or caspase 3 by intratracheal administration of small interfering RNA would ameliorate ALI in a clinically relevant double-hit mouse model of trauma induced septic lung injury. Male C57Bl/6 mice received small interfering (Fas, FADD, caspase 3) or control RNA 24 h before and 12 h after blunt chest trauma or sham procedures. Polymicrobial sepsis was induced by cecal ligation and puncture 24 h after chest trauma. Twelve or 24 h later, lung tissue, plasma, and bronchoalveolar lavage fluid were harvested. During ALI, lung apoptosis (active caspase 3 Western blotting, TUNEL staining) was substantially increased when compared with sham. Silencing of caspase 3 or FADD both markedly reduced pulmonary apoptosis. Fas- and FADD-small interfering RNA administration substantially decreased lung cytokine concentration, whereas caspase 3 silencing did not reduce lung inflammation. In addition, Fas silencing markedly decreased lung neutrophil infiltration. Interestingly, only in response to caspase 3 silencing, ALI-induced lung epithelial barrier dysfunction was substantially improved, and histological appearance was beneficially affected. Taken together, downstream inhibition of lung apoptosis via caspase 3 silencing proved to be superior in mitigating ALI when compared with upstream inhibition of apoptosis via Fas or FADD silencing, even in the presence of additional anti-inflammatory effects. This indicates a major pathophysiological role of lung apoptosis and suggests the importance of other than Fas-driven apoptotic pathways in trauma-induced septic ALI. PMID:23247118

    Abstract The aim of this study is to evaluate the hematological differences between septic and traumatic disseminated intravascular coagulation (DIC) using the rotational thromboelastometry (ROTEM). This retrospective study includes all sepsis or severe trauma patients transported to our emergency department who underwent ROTEM from 2013 to 2014. All patients were divided into 2 groups based on the presence of DIC diagnosed by the Japanese Association for Acute Medicine (JAAM) DIC score. We statistically analyzed the demographics, clinical characteristics, laboratory data, ROTEM findings (EXTEM and FIBTEM), and outcome. Fifty-seven patients (30 sepsis and 27 severe trauma) were included in primary analysis. Sepsis cases were significantly older and had higher systemic inflammatory response syndrome (SIRS) scores, whereas there were no significant differences in other parameters including Acute Physiology and Chronic Health Evaluation (APACHE) II score, sequential organ failure assessment (SOFA) score. Twenty-six patients (14 sepsis and 12 severe trauma) were diagnosed with DIC. The Septic DIC (S-DIC) group was significantly older and had higher DIC scores than the traumatic DIC (T-DIC) group. Hematologic examination revealed significantly higher CRP, fibrinogen, lower FDP, DD, and higher FDP/DD ratio were found in the S-DIC group in comparison with the T-DIC group. ROTEM findings showed that the A10, A20, and MCF in the FIBTEM test were significantly higher in the S-DIC group. However, no statistical differences were confirmed in the LI30, LI45, and ML in EXTEM test. The plasma fibrinogen level and fibrinogen based clot firmness in whole-blood test revealed statistical significance between septic and traumatic DIC patients. PMID:27495106

    2013-01-01

    Background The Whiplash Disability Questionnaire (WDQ) poses a validated tool for the assessment of patients who experience whiplash-associated disorders. A German translation and cross-cultural adaptation was recently produced and presented high validity and internal consistency. As a follow-up, the presented study tests the translated Whiplash Disability Questionnaire’s (WDQ-G) retest reliability and responsiveness to change. Methods The WDQ-G was assessed on three different measurement events: first upon entry (ME1), second four days after entry (ME2), and third at discharge (ME3). Test-retest reliability data from ME1 and ME2 was analysed in a group of stable patients to obtain the intraclass correlation coefficient (ICC) and the standard error of measurement (SEM). To test the instrument’s responsiveness, WDQ-G change data were compared to concurrent instruments. The probability of each instrument, to correctly distinguish patients of the stable phase (ME1 to ME2) from patients who deemed to have improved between from ME1 to ME3, was analysed. Results In total, 53 patients (35 females, age = 45 ± 12.2) were recruited. WDQ-G scores changed from ME1 to ME2 by 5.41 ± 11.6 points in a stable group. This corresponds to a test-retest reliability of ICC = 0.91 (95% CI = 0.80–0.95) with a SEM of 6.14 points. Minimal Detectable Change, at 95% confidence, was calculated to be 17 points change in scores. Area under Receiver Operator Characteristics of the WDQ-G’s responsiveness revealed a probability of 84.6% (95% CI = 76.2%–93%) to correctly distinguish between improved and stable patients. Optimal sensitivity (73.2%) and specificity (76.2%) was established at 11-point change. Conclusions High retest reliability and good responsiveness of the WDQ-G support clinical implementation of the translated version. The data suggest, that change in total score greater than eleven points can be interpreted as clinical relevant from a patient

    Purpose To our knowledge data on diagnostic angiography and angioembolization after renal trauma have been limited to single institution series with small numbers. We used the National Trauma Data Bank® to investigate national patterns of diagnostic angiography and angioembolization after blunt and penetrating renal trauma. Materials and Methods All renal injuries treated between 2002 and 2007 were identified in the National Trauma Data Bank by Abbreviated Injury Scale codes and converted to American Association for the Surgery of Trauma renal injury grades. Diagnostic angiography and angioembolization were identified by ICD-9 codes and examined. Initial angioembolization was considered a failure if subsequent therapy was needed. Repeat diagnostic angiography was not considered a failure. Results A total of 9,002 renal injuries were available for analysis. A total of 165 patients (2%) underwent diagnostic angiography after renal injury, including 77 (47%) who underwent concomitant angioembolization. Of the patients 78% sustained grade III–V renal injuries. Of the 77 patients with initial angioembolization 68 required successive therapy. Repeat angioembolization was the most common management choice (29% of patients). Secondary angioembolization was durable during the index hospitalization with success in 35 of 36 cases. Successive therapy was required after initial angioembolization for all grade IV and V renal injuries in 48 patients. The overall renal salvage rate was 92%, including 88% for grade IV and V injuries. Conclusions Successive therapy is common after initial management of renal injury by angioembolization. Close observation is highly recommended after initial angioembolization for grade IV–V renal injuries. National agreement on the use of diagnostic angiography and angioembolization is needed since these procedures may be overused after grade I–III renal injuries. PMID:21334643

    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

    Whiplash-associated disorder (WAD) represents a significant public health problem, resulting in substantial social and economic costs throughout the industrialized world. While many treatments have been advocated for patients with WAD, scientific evidence supporting their effectiveness is often lacking. A systematic review was conducted to evaluate the strength of evidence for various WAD therapies. Multiple databases (including Web of Science, EMBASE and PubMed) were searched to identify all studies published from January 1980 through March 2009 that evaluated the effectiveness of any clearly defined treatment for acute (less than two weeks), subacute (two to 12 weeks) or chronic (longer than 12 weeks) WAD. The present article, the fourth in a five-part series, evaluates the evidence for noninvasive interventions initiated during the chronic phase of WAD. Twenty-two studies that met the inclusion criteria were identified, 12 of which were randomized controlled trials with ‘good’ overall methodological quality (median Physiotherapy Evidence Database score of 6). For the treatment of chronic WAD, there is evidence to suggest that exercise programs are effective in relieving whiplash-related pain, at least over the short term. While the majority of a subset of nine studies supported the effectiveness of interdisciplinary interventions, the two randomized controlled trials provided conflicting results. Finally, there was limited evidence, consisting of one supportive case series each, that both manual joint manipulation and myofeedback training may provide some benefit. Based on the available research, exercise programs were the most effective noninvasive treatment for patients with chronic WAD, although many questions remain regarding the relative effectiveness of various exercise regimens.

    Trauma is a leading cause of death, with uncontrolled hemorrhage and exsanguination being the primary causes of preventable deaths during the first 24 h following trauma. Death usually occurs quickly, typically within the first 6 h after injury. One out of four patients arriving at the Emergency Department after trauma is already in hemodynamic and hemostatic depletion. This early manifestation of hemostatic depletion is referred to as the coagulopathy of trauma, which may distinguished as: (i) acute traumatic coagulopathy (ATC) and (ii) iatrogenic coagulopathy (IC). The principle drivers of ATC have been characterized by tissue trauma, inflammation, hypoperfusion/shock, and the acute activation of the neurohumoral system. Hypoperfusion leads to an activation of protein C with cleavage of activated factors V and VIII and the inhibition of plasminogen activator inhibitor-1 (PAI-1), with subsequent fibrinolysis. Endothelial damage and activation results in Weibel-Palade body degradation and glycocalyx shedding associated with autoheparinization. In contrast, there is an IC which occurs secondary to uncritical volume therapy, leading to acidosis, hypothermia, and hemodilution. This coagulopathy may, then, be an integral part of the "vicious cycle" when combined with acidosis and hypothermia. The awareness of the specific pathophysiology and of the principle drivers underlying the coagulopathy of trauma by the treating physician is paramount. It has been shown that early recognition prompted by appropriate and aggressive management can correct coagulopathy, control bleeding, reduce blood product use, and improve outcome in severely injured patients. This paper summarizes: (i) the current concepts of the pathogenesis of the coagulopathy of trauma, including ATC and IC, (ii) the current strategies available for the early identification of patients at risk for coagulopathy and ongoing life-threatening hemorrhage after trauma, and (iii) the current and updated European

    To evaluate the impact of a picture archiving and communication systems (PACS)-based software package on the requests for 3D reconstructions of multidetector CT (MDCT) data sets in the emergency radiology of a level 1 trauma center, we reviewed the number and type of physician requests for 3D reconstructions of MDCT data sets for patients admitted after sustaining multiple trauma, during a 12-month period (January 2003-December 2003). During the first 5 months of the study, 3D reconstructions were performed in dedicated workstations located separately from the emergency radiology CT interpretation area. During the last 7 months of the study, reconstructions were performed online by the attending radiologist or resident on duty, using a software package directly incorporated into the PACS workstations. The mean monthly number of 3D reconstructions requested during the two time periods was compared using Student's t test. The monthly mean +/- SD of 3D reconstructions performed before and after 3D software incorporation into the PACS was 34+/-7 (95% CI, 10-58) and 132+/-31 (95% CI, 111-153), respectively. This difference was statistically significant (p<0.0001). In the multiple trauma patient, implementation of PACS-integrated software increases utilization of 3D reconstructions of MDCT data sets.

    Objective. Inhibition of inflammation and free radical formation in the cochlea may be involved in antioxidant treatment in acute acoustic trauma. Procedure. Chinchilla were exposed to 105 dB sound pressure level octave band noise for 6 hours. One group of chinchilla was treated with antioxidants after noise exposure. Auditory brainstem responses, outer hair cell counts, and immunohistochemical analyses of biomarkers in the cochlea were conducted. Results. The antioxidant treatment significantly reduced hearing threshold shifts, outer hair cell loss, numbers of CD45+ cells, as well as 4-hydroxy-2-nonenal and nitrotyrosine formation in the cochlea. Conclusion. Antioxidant treatment may provide protection to sensory cells by inhibiting formation of reactive oxygen and nitrogen products and migration of mononuclear phagocytes in the cochlea. The present study provides further evidence of effectiveness of antioxidant treatment in reducing permanent hearing loss. PMID:21961007

    Acute acoustic trauma (AAT) results in oxidative stress to the cochlea through overproduction of cellular reactive oxygen, nitrogen, and other free radical species appearing from 1 h to 10 days after noise exposure. It has been shown that N-acetyl-L-cysteine (NAC), a glutathione prodrug, and acetyl-L-carnitine (ALCAR), a mitochondrial biogenesis agent, are effective in reducing noise-induced hearing loss. Phenyl N-tert-butylnitrone (PBN), a nitrone-based free radical trap, appears to suppress oxidative stress in a variety of disorders and several biological models. In this study, we tested whether 4-hydroxy PBN (4-OHPBN), a major metabolite of PBN, administered 4 h after noise exposure is effective in treating noise-induced hearing loss and whether a combination of antioxidant drugs (4-OHPBN plus NAC and 4-OHPBN plus NAC plus ALCAR) provides greater efficacy in attenuating AAT since each agent addresses different injury mechanisms. Chinchilla were exposed to a 105 dB octave-band noise centered at 4 kHz for 6 h. 4-OHPBN and combinations of antioxidant drugs were intraperitoneally administered beginning 4 h after noise exposure. Hearing threshold shifts in auditory brainstem responses and missing outer hair cell counts were obtained. 4-OHPBN reduced threshold shifts in a dose-dependent manner while both drug combinations showed greater effects. These results demonstrate that 4-OHPBN and combinations of antioxidants can effectively treat acute acoustic trauma and drug combinations may increase the effectiveness of treatment and decrease the required individual medication dose.

    Orbital trauma is one of the most common reasons for ophthalmology specialty consultation in the emergency department setting. We survey the literature from 1990 to present to describe the role of computed tomography (CT), magnetic resonance imaging (MRI) and their associated angiography in some of the most commonly encountered orbital trauma conditions. CT orbit can often detect certain types of foreign bodies, lens dislocation, ruptured globe, choroidal or retinal detachments, or cavernous sinus thrombosis and thus complement a bedside ophthalmic exam that can sometimes be limited in the setting of trauma. CT remains the workhorse for acute orbital trauma owing to its rapidity and ability to delineate bony abnormalities; however MRI remains an important modality in special circumstances such as soft tissue assessment or with organic foreign bodies.

    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.

    1984-01-01

    In bad cases of whiplash injury of the cervical spine the post-accidental course is complicated by pain, vegetative dysfunctional syndromes and by psychic and psychiatric disorders over many years. There is no satisfactory concept to understand the pathophysiology of these processes. The paper deals with the possibility of a reflex dystrophy. Sympathetic reflex dystrophy syndromes are seen principally in patients with joint, tendon or vascular lesions. In case of whiplash injury, it would concern the cervical spine itself as well as visceral organs including the central nervous system. For the CNS the lymphostatic encephalopathy is a well defined entity. Above all, a reflex dystrophy develops on the basis of a special personality structure. In case of psychic and psychiatric complaints after whiplash injury patients with a so called Sudeck-personality should not be suspected to aggravate; in contrast, especially in these patients complications by reflex dystrophy are credible. Consequences for the assessment and for rehabilitation are discussed. PMID:6475217

    Traumatic causes of orbital apex and superior orbital fissure syndrome are uncommon. The authors present the first case of a traumatic superior orbital fissure syndrome simulating orbital apex syndrome, with loss of vision from posterior ischemic optic neuropathy. A 35-year-old man was initially felt to have a right orbital apex syndrome with left craniofacial and orbital trauma. CT revealed left orbital fractures, a right superior orbital fissure fracture, a retained metallic foreign body in the right sphenoid sinus, and a right frontoparietal subdural hematoma. CT angiography showed a secondary dissection and occlusion of the right internal carotid artery from osseous erosion of the posterolateral wall of the sphenoid sinus. Internal carotid artery dissection is a possible, though rare, cause of ischemic optic neuropathy. The right pseudo-orbital apex syndrome resulted from a mechanical superior orbital fissure syndrome and posterior ischemic optic neuropathy from an internal carotid artery dissection. PMID:25216200

    Objectives Whiplash-associated disorders (WAD) are the most common injuries that are associated with car collisions in Japan and many Western countries. However, there is no clear evidence regarding the potential risk factors for poor recovery from WAD. Therefore, we used an online survey of the Japanese population to examine the association between potential risk factors and the persistence of symptoms in individuals with WAD. Materials and Methods An online survey was completed by 127,956 participants, including 4,164 participants who had been involved in a traffic collision. A random sample of the collision participants (n = 1,698) were provided with a secondary questionnaire. From among the 974 (57.4%) respondents to the secondary questionnaire, we selected 183 cases (intractable neck pain that was treated over a period of 6 months) and 333 controls (minor neck pain that was treated within 3 months). Multivariable logistic regression analysis was used to evaluate the potential risk factors for prolonged treatment of WAD. Results Female sex, the severity of the collision, poor expectations of recovery, victim mentality, dizziness, numbness or pain in the arms, and lower back pain were associated with a poor recovery from WAD. Conclusions In the present study, the baseline symptoms (dizziness, numbness or pain in the arms, and lower back pain) had the strongest associations with prolonged treatment for WAD, although the psychological and behavioral factors were also important. These risk factors should be considered when evaluating patients who may have the potential for poor outcomes. PMID:26147998

    A retrospective analysis of insurance data was made of 600 individuals claiming compensation for whiplash following motor vehicle accidents. Three hundred randomly selected claimants who had settled their injury claims within 9 months of the accident were compared with 300 who had settled more than 24 months after the accident. We compared the two groups to identify possible risk factors for prolonged recovery, for which settlement time greater than 24 months was a marker. Variables considered included demographic factors, type of collision, degree of vehicle damage, workers compensation, prior claim or neck disability, treatment and time to settlement. Consulting a solicitor was associated with a highly significant, four-fold increase of late settlement of the claim. A concurrent workers' compensation claim, prior neck disability and undergoing physiotherapy or chiropractic treatment were weakly associated with late settlement. The degree of damage to the vehicle (as indicated by cost of repairs) was not a significant predictor of late settlement. Late settlement may be the direct effect of legal intervention, independent of the severity of the injury. Whilst the financial benefit to the claimant of consulting a solicitor is apparent, the benefit of prolonged disability is not. It may be to the advantage of both insurers and claimants if those likely to proceed to late settlement could be recognised early and their claims settled expeditiously. PMID:15160316

    There is increasing evidence of central hyperexcitability in chronic whiplash-associated disorders (cWAD). However, little is known about how an apparently simple cervical spine injury can induce changes in cerebral processes. The present study was designed (1) to validate previous results showing alterations of regional cerebral blood flow (rCBF) in cWAD, (2) to test if central hyperexcitability reflects changes in rCBF upon non-painful stimulation of the neck, and (3) to verify our hypothesis that the missing link in understanding the underlying pathophysiology could be the close interaction between the neck and midbrain structures. For this purpose, alterations of rCBF were explored in a case-control study using H2(15)O positron emission tomography, where each group was exposed to four different conditions, including rest and different levels of non-painful electrical stimulation of the neck. rCBF was found to be elevated in patients with cWAD in the posterior cingulate and precuneus, and decreased in the superior temporal, parahippocampal, and inferior frontal gyri, the thalamus and the insular cortex when compared with rCBF in healthy controls. No differences in rCBF were observed between different levels of electrical stimulation. The alterations in regions directly involved with pain perception and interoceptive processing indicate that cWAD symptoms might be the consequence of a mismatch during the integration of information in brain regions involved in pain processing.

    Substantial theoretical, empirical, and clinical work examines trauma as it relates to individual victims and perpetrators. 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.

    Whiplash injuries continue to have significant societal cost; however, the mechanism and location of whiplash injury is still under investigation. Recently, the upper cervical spine ligaments, particularly the alar ligament, have been identified as a potential whiplash injury location. In this study, a detailed and validated explicit finite element model of a 50th percentile male cervical spine in a seated posture was used to investigate upper cervical spine response and the potential for whiplash injury resulting from vehicle crash scenarios. This model was previously validated at the segment and whole spine levels for both kinematics and soft tissue strains in frontal and rear impact scenarios. The model predicted increasing upper cervical spine ligament strain with increasing impact severity. Considering all upper cervical spine ligaments, the distractions in the apical and alar ligaments were the largest relative to their failure strains, in agreement with the clinical findings. The model predicted the potential for injury to the apical ligament for 15.2 g frontal or 11.7 g rear impacts, and to the alar ligament for a 20.7 g frontal or 14.4 g rear impact based on the ligament distractions. Future studies should consider the effect of initial occupant position on ligament distraction. PMID:22284991

    Background Millions of children are affected by acute medical events annually, creating need for resources to promote recovery. While web-based interventions promise wide reach and low cost for users, development can be time- and cost-intensive. A systematic approach to intervention development can help to minimize costs and increase likelihood of effectiveness. Using a systematic approach, our team integrated evidence on the etiology of traumatic stress, an explicit program theory, and a user-centered design process to intervention development. Objective To describe evidence and the program theory model applied to the Coping Coach intervention and present pilot data evaluating intervention feasibility and acceptability. Method Informed by empirical evidence on traumatic stress prevention, an overarching program theory model was articulated to delineate pathways from a) specific intervention content to b) program targets and proximal outcomes to c) key longer-term health outcomes. Systematic user-testing with children ages 8–12 (N = 42) exposed to an acute medical event and their parents was conducted throughout intervention development. Results Functionality challenges in early prototypes necessitated revisions. Child engagement was positive throughout revisions to the Coping Coach intervention. Final pilot-testing demonstrated promising feasibility and high user-engagement and satisfaction. Conclusion Applying a systematic approach to the development of Coping Coach led to the creation of a functional intervention that is accepted by children and parents. Development of new e-health interventions may benefit from a similar approach. Future research should evaluate the efficacy of Coping Coach in achieving targeted outcomes of reduced trauma symptoms and improved health-related quality of life. PMID:25844276

    Depression is common in whiplash-associated disorders (WAD). Our objectives were to identify factors associated with depressive symptomatology occurring in the initial stages of WAD, and to identify factors predicting the course of depressive symptoms. A population-based cohort of adults sustaining traffic-related WAD was followed at 6 weeks, 3, 6, 9, and 12 months. Baseline measures (assessed a median of 11 days post-crash) included demographic and collision-related factors, prior health, and initial post-crash pain and symptoms. Depressive symptomatology was assessed at baseline and at each follow-up using the Centre for Epidemiological Studies Depression Scale (CES-D). We included only those who participated at all follow-ups (n = 3,452; 59% of eligible participants). Using logistic regression, we identified factors associated with initial (post-crash) depression. Using multinomial regression, we identified baseline factors predicting course of depression. Courses of depression were no depression; initial depression that resolves, recurs or persists, and later onset depression. Factors associated with initial depression included greater neck and low back pain severity, greater percentage of body in pain, numbness/tingling in arms/hand, dizziness, vision problems, post-crash anxiety, fracture, prior mental health problems, and poorer general health. Predictors of persistent depression included older age, greater initial neck and low back pain, post-crash dizziness, vision and hearing problems, numbness/tingling in arms/hands, anxiety, prior mental health problems, and poorer general health. Recognition of these underlying risk factors may assist health care providers to predict the course of psychological reactions and to provide effective interventions. PMID:20127261

    The most common consequences of acute acoustic trauma (AAT) are hearing loss at frequencies above 3 kHz and tinnitus. In this study, we have used functional Magnetic Resonance Imaging (fMRI) to visualize neuronal activation patterns in military adults with AAT and various tinnitus sequelae during an auditory “oddball” attention task. AAT subjects displayed overactivities principally during reflex of target sound detection, in sensorimotor areas and in emotion-related areas such as the insula, anterior cingulate and prefrontal cortex, in premotor area, in cross-modal sensory associative areas, and, interestingly, in a region of the Rolandic operculum that has recently been shown to be involved in tympanic movements due to air pressure. We propose further investigations of this brain area and fine middle ear investigations, because our results might suggest a model in which AAT tinnitus may arise as a proprioceptive illusion caused by abnormal excitability of middle-ear muscle spindles possibly link with the acoustic reflex and associated with emotional and sensorimotor disturbances.

This section covers situations in trauma unique to the geriatric population, who are often under-triaged and have significant injuries underestimated. Topics covered include age-related pathophysiological changes, underlying existing medical conditions and certain daily medications that increase the risk of serious injury in elderly trauma patients. Diagnostic evaluation of this group requires liberal testing, imaging, and a multidisciplinary team approach. Topics germane to geriatric trauma including hypothermia, elder abuse, and depression and suicide are also covered. PMID:27475011

    OBJECT Blast-induced neurotrauma (BINT), if not fatal, is nonetheless potentially crippling. It can produce a wide array of acute symptoms in moderate-to-severe exposures, but mild BINT (mBINT) is characterized by the distinct absence of acute clinical abnormalities. The lack of observable indications for mBINT is particularly alarming, as these injuries have been linked to severe long-term psychiatric and degenerative neurological dysfunction. Although the long-term sequelae of BINT are extensively documented, the underlying mechanisms of injury remain poorly understood, impeding the development of diagnostic and treatment strategies. The primary goal of this research was to recapitulate primary mBINT in rodents in order to facilitate well-controlled, long-term investigations of blast-induced pathological neurological sequelae and identify potential mechanisms by which ongoing damage may occur postinjury. METHODS A validated, open-ended shock tube model was used to deliver blast overpressure (150 kPa) to anesthetized rats with body shielding and head fixation, simulating the protective effects of military-grade body armor and isolating a shock wave injury from confounding systemic injury responses, head acceleration, and other elements of explosive events. Evans Blue-labeled albumin was used to visualize blood-brain barrier (BBB) compromise at 4 hours postinjury. Iba1 staining was used to visualize activated microglia and infiltrating macrophages in areas of peak BBB compromise. Acrolein, a potent posttraumatic neurotoxin, was quantified in brain tissue by immunoblotting and in urine through liquid chromatography with tandem mass spectrometry at 1, 2, 3, and 5 days postinjury. Locomotor behavior, motor performance, and short-term memory were assessed with open field, rotarod, and novel object recognition (NOR) paradigms at 24 and 48 hours after the blast. RESULTS Average speed, maximum speed, and distance traveled in an open-field exploration paradigm did not show

    Whiplash-associated disorder (WAD) represents a significant public health problem, resulting in a substantial socioeconomic burden throughout the industrialized world, wherever costs are documented. While many treatments have been advocated for patients with WAD, scientific evidence of their effectiveness is often lacking. A systematic review was conducted to evaluate the strength of evidence supporting various WAD therapies. Multiple databases (including Web of Science, EMBASE and PubMed) were searched to identify all studies published from January 1980 through March 2009 that evaluated the effectiveness of any clearly defined treatment for acute (less than two weeks), subacute (two to 12 weeks) or chronic (longer than 12 weeks) WAD. The present article, the first in a five-part series, provides an overview of the review methodology as well as a summary and discussion of the review’s main findings. Eighty-three studies met the inclusion criteria, 40 of which were randomized controlled trials. The majority of studies (n=47) evaluated treatments initiated in the chronic stage of the disorder, while 23 evaluated treatments for acute WAD and 13 assessed therapies for subacute WAD. Exercise and mobilization programs for acute and chronic WAD had the strongest supporting evidence, although many questions remain regarding the relative effectiveness of various protocols. At present, there is insufficient evidence to support any treatment for subacute WAD. For patients with chronic WAD who do not respond to conventional treatments, it appears that radiofrequency neurotomy may be the most effective treatment option. The present review found a relatively weak but growing research base on which one could make recommendations for patients at any stage of the WAD continuum. Further research is needed to determine which treatments are most effective at reducing the disabling symptoms associated with WAD. PMID:21038007

    This study determines whether acute respiratory distress syndrome (ARDS) is an independent risk factor for an increased risk of post-traumatic brain injury (TBI) stroke during 3-month, 1-year, and 5-year follow-ups, respectively, after adjusting for other covariates. Clinical data for the analysis were from the National Health Insurance Database 2000, which covered a total of 2121 TBI patients and 101 patients with a diagnosis of TBI complicated with ARDS (TBI-ARDS) hospitalized between January 1, 2001 and December 31, 2005. Each patient was tracked for 5 years to record stroke occurrences after discharge from the hospital. The prognostic value of TBI-ARDS was evaluated using a multivariate Cox proportional hazard model. The main outcome found that stroke occurred in nearly 40% of patients with TBI-ARDS, and the hazard ratio for post-TBI stroke increased fourfold during the 5-year follow-up period after adjusting for other covariates. The increased risk of hemorrhagic stroke in the ARDS group was considerably higher than in the TBI-only cohort. This is the first study to report that post-traumatic ARDS yielded an approximate fourfold increased risk of stroke in TBI-only patients. We suggest intensive and appropriate medical management and intensive follow-up of TBI-ARDS patients during the beginning of the hospital discharge. PMID:26426583

    Chest trauma is a frequent problem arising from lesions caused by domestic and occupational activities and especially road traffic accidents. These injuries can be analyzed from distinct points of view, ranging from consideration of the most severe injuries, especially in the context of multiple trauma, to the specific characteristics of blunt and open trauma. In the present article, these injuries are discussed according to the involvement of the various thoracic structures. Rib fractures are the most frequent chest injuries and their diagnosis and treatment is straightforward, although these injuries can be severe if more than three ribs are affected and when there is major associated morbidity. Lung contusion is the most common visceral lesion. These injuries are usually found in severe chest trauma and are often associated with other thoracic and intrathoracic lesions. Treatment is based on general support measures. Pleural complications, such as hemothorax and pneumothorax, are also frequent. Their diagnosis is also straightforward and treatment is based on pleural drainage. This article also analyzes other complex situations, notably airway trauma, which is usually very severe in blunt chest trauma and less severe and even suitable for conservative treatment in iatrogenic injury due to tracheal intubation. Rupture of the diaphragm usually causes a diaphragmatic hernia. Treatment is always surgical. Myocardial contusions should be suspected in anterior chest trauma and in sternal fractures. Treatment is conservative. Other chest injuries, such as those of the great thoracic and esophageal vessels, are less frequent but are especially severe. PMID:21640287

    The Steller sea lion, Eumetopias jubatus, has experienced regionally divergent population trends over recent decades. One potential mechanism for this disparity is that local factors cause reduced health and, therefore, reduced survival of individuals. The use of blood parameters to assess sea lion health may help to identify whether malnutrition, disease and stress are important drivers of current trends, but such assessments require species-specific knowledge of how parameters respond to various health challenges. We used principal components analysis to identify which key blood parameters (principal analytes) best described changes in health for temporarily captive juvenile Steller sea lions in known conditions. Generalized additive mixed models were used to estimate the changes in principal analytes with food intake, time in captivity and acute trauma associated with hot-iron branding and transmitter implant surgery. Of the 17 blood parameters examined, physiological changes for juvenile sea lions were best described using the following six principal analytes: red blood cell counts, white blood cell counts, globulin, platelets, glucose and total bilirubin. The white blood cell counts and total bilirubin declined over time in captivity, whereas globulin increased. Elevated red blood cell counts, white blood cell counts and total bilirubin and reduced globulin values were associated with lower food intake. After branding, white blood cell counts were elevated for the first 30 days, while globulin and platelets were elevated for the first 15 days only. After implant surgery, red blood cell counts and globulin remained elevated for 30 days, while white blood cell counts remained elevated during the first 15 days only. Glucose was unassociated with the factors we studied. These results were used to provide expected ranges for principal analytes at different levels of food intake and in response to the physical challenges of branding and implant surgery

    Video gaming injuries are classically regarded as eccentric accidents and novelty diagnoses. A case of an anterior cruciate ligament (ACL) tear sustained during Wii boxing spurned us to review the literature for other Wii-related injuries and Wii-based posttraumatic rehabilitation. The English literature listed in PubMed was systematically reviewed by searching for "Wii (trauma or injury or fracture)." Full-text articles were included after duplicate, blinded review. The type and treatment of injury as well as the Wii-based rehabilitation programs found were analyzed. Additionally, a new case of an acute ACL tear-sustained playing, Wii boxing, is additionally presented. After exclusion of irrelevant articles, 13 articles describing Wii-related injuries were included reporting on 3 fractures, 6 nonosseous, 2 overuse injuries, and 2 rehabilitation programs using Wii for posttraumatic rehabilitation. Among the presented Wii-related injuries, only 12.5% were treated conservatively, whereas 87.5% underwent either surgical or interventional treatment. Because of the reported case, the literature search was limited to Wii-related injuries excluding other video games. Another limitation of this article lies in the fact that mainly case reports but no controlled trials exist on the topic. Assumingly, primarily the more severe injuries are reported in the literature with an unknown number of possibly minor injuries. Motion-controlled video games, such as Wii, are becoming increasingly popular as a recreational entertainment. Because of their wide acceptance and entertaining nature, they are also increasingly recognized as a tool in rehabilitation. However, although the activity is simulated, injuries are real. Our systematic review shows that Wii gaming can lead to severe injuries, sometimes with lasting limitations. PMID:25816033

    With the increased incidence of whiplash injury following the introduction of compulsory car seat belts, a large number of reports have dealt with the aftermath of this condition. Previous studies, however, focused on somatic symptoms on the one hand or considered only psychological or neuropsychological variables on the other hand, often in loosely defined or selected groups of patients. No study so far has analyzed the long-term outcome in a nonselected group of patients using a clear injury definition considering patient history; somatic, radiologic, and neuropsychological findings; and features of the injury mechanisms assessed soon after trauma and during follow-up. the present investigation was designed to assess these combined factors. According to a strict definition of whiplash injury, we assessed a consecutive nonselected sample of 117 patients with recent injury who had similar sociocultural and educational backgrounds. The patients had been in automobile crashes and were all equally covered by accident insurance according to the country-wide scheme. Initial examination was performed 7.2 +/- 4.2 days after trauma, and follow-up examinations 3, 6, 12, and 24 months later. At baseline, features of injury mechanism, subjective complaints, and different aspects of patient history were documented and cervical spine X rays performed. At all examinations patients underwent neurologic examination and cognitive and psychosocial factor assessment. At 2 years, patients were divided into symptomatic and asymptomatic groups and then compared with regard to the initial findings. In addition, symptomatic patients who were disabled at the 2-year follow-up examination and symptomatic patients not disabled (that is, they were able to work at the pretraumatic level) were compared regarding initial and 2-year findings. At 2 years, 18% of patients still had injury-related symptoms. With regard to baseline findings the following significant differences were found: Symptomatic

    The present study was undertaken to evaluate if MRI within 2 days of a motor vehicle accident could reveal pathology of importance for understanding long-term disability after whiplash neck-sprain injuries. As part of a prospective study cervical and cerebral MRI was performed on 40 neck sprain patients with whiplash injury after car accidents. The imaging was done within 2 days of the injury to make sure that any neck muscle bleeding, oedema or other soft tissue injuries could be detected. The MRI findings from the patients were both correlated to reported symptoms 6 months after the accident and compared to a control group of 20 volunteers. The MRI of both brain and neck revealed no significant differences between the patients and the control group. When the patients were grouped according to the main MRI findings at intake and compared according to the development of subjective symptoms reported by the patients, the only significant difference was more headaches at 6 months in the groups with disk pathology or spondylosis when compared to the group with no pathology. In conclusion, MRI within 2 days of the whiplash neck-sprain injury could not detect pathology connected to the injury nor predict symptom development and outcome. PMID:9764227

    In vehicle collisions, the occupant's torso is accelerated in a given direction while the unsupported head tends to lag behind. This mechanism results in whiplash motion to the neck. In whiplash experiments conducted for animals, pressure transients have been recorded in the spinal canal. It was hypothesized that the transients caused dorsal root ganglion dysfunction. Neck motion introduces volume changes inside the vertebral canal. The changes require an adaptation which is likely achieved by redistribution of blood volume in the internal vertebral venous plexus (IVVP). Pressure transients then arise from the rapid redistribution. The present study aimed to explore the hypothesis theoretically and analytically. Further, the objectives were to quantify the effect of the neck motion on the pressure generation and to identify the physical factors involved. We developed a hydrodynamic system of tubes that represent the IVVP and its lateral intervertebral vein connections. An analytical model was developed for an anatomical geometrical relation that the venous blood volume changes with respect to the vertebral angular displacement. This model was adopted in the hydrodynamic tube system so that the system can predict the pressure transients on the basis of the neck vertebral motion data from a whiplash experiment. The predicted pressure transients were in good agreement with the earlier experimental data. A parametric study was conducted and showed that the system can be used to assess the influences of anatomical geometrical properties and vehicle collision severity on the pressure generation.

    There are few diagnostic tools for chronic musculoskeletal pain as structural imaging methods seldom reveal pathological alterations. This is especially true for Whiplash Associated Disorder, for which physical signs of persistent injuries to the neck have yet to be established. Here, we sought to visualize inflammatory processes in the neck region by means Positron Emission Tomography using the tracer 11C-D-deprenyl, a potential marker for inflammation. Twenty-two patients with enduring pain after a rear impact car accident (Whiplash Associated Disorder grade II) and 14 healthy controls were investigated. Patients displayed significantly elevated tracer uptake in the neck, particularly in regions around the spineous process of the second cervical vertebra. This suggests that whiplash patients have signs of local persistent peripheral tissue inflammation, which may potentially serve as a diagnostic biomarker. The present investigation demonstrates that painful processes in the periphery can be objectively visualized and quantified with PET and that 11C-D-deprenyl is a promising tracer for these purposes.

    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. PMID:26490501

  4. The PanAM study: a multi-center, double-blinded, randomized, non-inferiority study of paracetamol versus non-steroidal anti-inflammatory drugs in treating acute musculoskeletal trauma

    Background Acute musculoskeletal trauma, including strains, sprains or contusions, occur frequently. Pain management is a crucial component of treatment. However, there is no convincing evidence which drug is superior in managing pain in these patients. The aim of the PanAM Study is to compare analgesic efficacy of three strategies of pain management: paracetamol, diclofenac, or a combination of both in patients with acute musculoskeletal trauma. Methods/design The PanAM Study is a multi-center, double blind randomized controlled trial with non-inferiority design. Included are adult patients presenting to an academic, urban Emergency Department or to a General Practice with acute, blunt, traumatic limb injury. In total, 547 patients will be included using a predefined list of exclusion criteria, to be allocated by randomization to treatment with paracetamol + placebo diclofenac, diclofenac + placebo paracetamol or paracetamol + diclofenac. The hypothesis is that paracetamol will not be inferior to treatment with diclofenac, or the combination of both. Primary outcome will be between-group differences in decrease in pain, measured with Numerical Rating Scales at baseline and at 90 minutes after study drug administration. Secondary outcomes are Numerical Rating Scales at 30 and 60 minutes and measured frequently during three consecutive days after discharge; occurrence of adverse effects; patient satisfaction and an analysis of quality of life and cost-effectiveness. Recruitment started July 2013 and is expected to last a year. Discussion With this multi-center randomized clinical trial we will investigate whether treatment with paracetamol alone is not inferior to diclofenac alone or a combination of both drugs in adult patients with acute musculoskeletal trauma. The main relevance of the trial is to demonstrate the benefits and risks of three commonly used treatment regimens for musculoskeletal trauma. Data that lead to the prevention of severe Non

    ABSTRACT Acute trauma coagulopathy (ATC) is seen in 30% to 40% of severely injured casualties. Early use of blood products attenuates ATC, but the timing for optimal effect is unknown. Emergent clinical practice has started prehospital deployment of blood products (combined packed red blood cells and fresh frozen plasma [PRBCs:FFP], and alternatively PRBCs alone), but this is associated with significant logistical burden and some clinical risk. It is therefore imperative to establish whether prehospital use of blood products is likely to confer benefit. This study compared the potential impact of prehospital resuscitation with (PRBCs:FFP 1:1 ratio) versus PRBCs alone versus 0.9% saline (standard of care) in a model of severe injury. Twenty-four terminally anesthetised Large White pigs received controlled soft tissue injury and controlled hemorrhage (35% blood volume) followed by a 30-min shock phase. The animals were allocated randomly to one of three treatment groups during a 60-min prehospital evacuation phase: hypotensive resuscitation (target systolic arterial pressure 80 mmHg) using either 0.9% saline (group 1, n = 9), PRBCs:FFP (group 2, n = 9), or PRBCs alone (group 3, n = 6). Following this phase, an in-hospital phase involving resuscitation to a normotensive target (110 mmHg systolic arterial blood pressure) using PRBCs:FFP was performed in all groups. There was no mortality in any group. A coagulopathy developed in group 1 (significant increase in clot initiation and dynamics shown by TEG [thromboelastography] R and K times) that persisted for 60 to 90 min into the in-hospital phase. The coagulopathy was significantly attenuated in groups 2 and 3 (P = 0.025 R time and P = 0.035 K time), which were not significantly different from each other. Finally, the volumes of resuscitation fluid required was significantly greater in group 1 compared with groups 2 and 3 (P = 0.0067) (2.8 ± 0.3 vs. 1.9 ± 0.2 and 1.8 ± 0.3 L, respectively).

    A classification of injury and a follow-up schedule were proposed by the Quebec Task Force (QTF) in 1995. No general agreement about the clinical usefulness of the WAD-classification or of the suggested follow-up regimen exists. A series of 186 consecutive cases seen in the emergency room during the acute phase after a whiplash injury was prospectively studied for 1 year. All findings including history and physical findings were recorded using standardized QTF protocols. In one group follow-up visits were done according to the QTF regimen: at 1, 3, 6, 12 weeks and 1 year after the accident; in a control group no visit was scheduled. The outcome variable was neck pain at 1 year after the accident. After 1 year, 18% of the total number of patients had significant neck pain. Risk factors for chronic neck pain at 1 year after whiplash injury were: neck pain before the accident and a high degree of emotional distress at the time of the accident; both factors independently associated with a tenfold increased risk of developing chronic neck pain. Neither the WAD classification nor the QTF follow-up regimen could be linked to a better outcome. In this study the outcome was associated with patient-specific characteristics and not with physical signs of injury, the depth of the initial evaluation or the follow-up regimen. PMID:18427841

    Purpose To investigate the presence of subgroups in chronic whiplash-associated disorders (WAD) based on pain thresholds for pressure (PPT), cold (CPT), and heat (HPT) and to compare these subgroups with respect to symptomatology, disability, and health aspects. Methods Two groups of female subjects – patients with chronic WAD (n = 28) and healthy controls (CON; n = 29) – were investigated. Quantitative sensory testing (QST) for thermal thresholds and algometry for PPT at four sites in the body (over the trapezius and tibialis anterior bilaterally) were determined. Habitual pain intensities, psychological strain, disability, and health aspects were registered using a questionnaire. Results A cluster analysis based on PPT, CPT, and HPT identified two subgroups of chronic WAD: one sensitive subgroup (s-WAD; n = 21), and one less sensitive subgroup (ls-WAD; n = 6). S-WAD displayed widespread hyperalgesia, whereas ls-WAD had localized hyperalgesia in the neck area, with tendencies to supernormal values in remote areas of the body. Generally, s-WAD had a significantly worse situation than the CON with respect to symptomatology, disability, and health aspects. The ls-WAD group was intermediary between s-WAD and CON in these aspects. Conclusion Different explanations, eg, severity of the pain condition per se, etiological factors, and pre-trauma differences in pain sensitivity, may exist for the differences in pain thresholds between the two subgroups. Future research should investigate the role of pain thresholds in the chronic stage to determine the efficacy of treatment interventions. PMID:23166449

    Trauma - accidental or intentional injury - is a major health and social problem. It is still the chief cause of death in people between the ages of 1 and 38 years. In the United States, the mortality due to trauma between the ages of 15 and 24 years increased by 13% from 1960 to 1978. During the same period, the mortality for people aged 25 to 64 years declined by 16%. Murders have increased from 8464 in 1960, to 26 000 in 1982. The overall death rate of American teenagers and young adults is 50% higher than that of their counterparts in Britain, Sweden and Japan. Trauma affects young, productive citizens, and the estimated costs for death, disability and loss of productivity exceed $230 million a day. The most tragic statistic is that at least 40% of the deaths are needless and preventable if better treatment and prevention programs were available. Trauma deaths that might be prevented are those due to motor vehicle accidents, homicide, burns, and alcohol and drug abuse. In this paper suggestions for prevention are made. They include improved crash worthiness of motor vehicles, revocation of drunk drivers' licences, use of devices that limit drunk drivers, increased tax on alcohol and random breathalyser tests, and the use of seat belts and motorcycle helmets. Control of hand-guns and burn characteristics of cigarettes could also reduce deaths. The problems and issues in trauma care can be divided into two broad categories: system and professional. System problems include prehospital care, in-hospital care, rehabilitation and prevention. Professional problems include education, research, economics, and quality.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6478325

    OBJECTIVE To provide an evidence-based clinical practice guideline for the chiropractic cervical treatment of adults with acute or chronic neck pain not due to whiplash. This is a considerable health concern considered to be a priority by stakeholders, and about which the scientific information was poorly organized. OPTIONS Cervical treatments: manipulation, mobilization, ischemic pressure, clinic- and home-based exercise, traction, education, low-power laser, massage, transcutaneous electrical nerve stimulation, pillows, pulsed electromagnetic therapy, and ultrasound. OUTCOMES The primary outcomes considered were improved (reduced and less intrusive) pain and improved (increased and easier) ranges of motion (ROM) of the adult cervical spine. EVIDENCE An “extraction” team recorded evidence from articles found by literature search teams using 4 separate literature searches, and rated it using a Table adapted from the Oxford Centre for Evidence-based Medicine. The searches were 1) Treatment; August, 2003, using MEDLINE, CINAHL, AMED, MANTIS, ICL, The Cochrane Library (includes CENTRAL), and EBSCO, identified 182 articles. 2) Risk management (adverse events); October, 2004, identified 230 articles and 2 texts. 3) Risk management (dissection); September, 2003, identified 79 articles. 4) Treatment update; a repeat of the treatment search for articles published between September, 2003 and November, 2004 inclusive identified 121 articles. VALUES To enable the search of the literature, the authors (Guidelines Development Committee [GDC]) regarded chiropractic treatment as including elements of “conservative” care in the search strategies, but not in the consideration of the range of chiropractic practice. Also, knowledge based only on clinical experience was considered less valid and reliable than good-caliber evidence, but where the caliber of the relevant evidence was low or it was non-existent, unpublished clinical experience was considered to be equivalent to

    Background: Whiplash patients regard cervicogenic headache (CEH) as the most burdensome symptom of their condition. Sufferers experience a significant degree of disability from headache, associated neck pain and disability, and sleep disturbance. Lateral C1/2 joint pulsed radiofrequency (PRF) treatment has been shown to produce significant relief from headache in patients with CEH. Objectives: The objective of this retrospective questionnaire study of 45 consecutive whiplash patients with CEH who had undergone antero-lateral atlantoaxial joint pulsed radiofrequency treatment (AA PRF) was to evaluate the treatment’s long-term effects on pain-related disability and health-related quality of life. Patients and Methods: Four questionnaires were sent to all 45 patients who had undergone AA PRF: 1) The short form-36 (SF-36); 2) The neck disability index (NDI); 3) The medical outcome scale-sleep scale (MOS-SS); 4) The headache impact test-6 (HIT-6). All 45 patients received AA PRF under fluoroscopic guidance. PRF treatment was conducted at 45 V with a pulsed frequency of 4 Hz and a pulsed width of 10 ms for 4 minutes . Results: Patients who responded to the procedure reported lower pain scores at 2, 6, and 12 months of follow-up compared to nonresponders. More important, patients reported marked improvements in headache impact (P < 0.01), neck-disability scores (P < 0.01), awakening due to headache (P < 0.01), and sleep problems (9-item; P < 0.05) on the MOS-SS. Responders to the procedure also reported a significantly higher health-related quality of life in terms of bodily pain (P < 0.05) and health change (P < 0.01) on the SF-36. Conclusions: In light of the inherent limitations of our retrospective study, AA PRF treatment can only be tentatively viewed as a promising treatment modality for whiplash patients with CEH and is subject to validation in future studies.

  12. Head and neck control varies with perturbation acceleration but not jerk: implications for whiplash injuries

    Siegmund, Gunter P; Blouin, Jean-Sébastien

    2009-01-01

    Recent studies have proposed that a high rate of acceleration onset, i.e. high jerk, during a low-speed vehicle collision increases the risk of whiplash injury by triggering inappropriate muscle responses and/or increasing peak head acceleration. Our goal was to test these proposed mechanisms at realistic jerk levels and then to determine how collision jerk affects the potential for whiplash injuries. Twenty-three seated volunteers (8 F, 15 M) were exposed to multiple experiments involving perturbations simulating the onset of a vehicle collision in eyes open and eyes closed conditions. In the first experiment, subjects experienced five forward and five rearward perturbations to look for the inappropriate muscle responses and ‘floppy’ head kinematics previously attributed to high jerk perturbations. In the second experiment, we independently varied the jerk (∼125 to 3 000 m s−3) and acceleration (∼0.65 to 2.6 g) of the perturbation to assess their effect on the electromyographic (EMG) responses of the sternocleidomastoid (SCM), scalene (SCAL) and cervical paraspinal (PARA) muscles and the kinematic responses of the head and neck. In the first experiment, we found neither inappropriate muscle responses nor floppy head kinematics when subjects had their eyes open, but observed two subjects with floppy head kinematics with eyes closed. In the second experiment, we found that about 70% of the variations in the SCM and SCAL responses and about 95% of the variations in head/neck kinematics were explained by changes in perturbation acceleration in both the eyes open and eyes closed conditions. Less than 2% of the variation in the muscle and kinematic responses was explained by changes in perturbation jerk and, where significant, response amplitudes diminished with increasing jerk. Based on these findings, collision jerk appears to have little or no role in the genesis of whiplash injuries in low-speed vehicle crashes. PMID:19237420

    Background The cervical muscles are considered a potential site of whiplash injury, and there are many impact scenarios for whiplash injury. There is a need to understand the cervical muscle response under non-conventional whiplash impact scenarios, including variable head position and impact direction. Methods Twenty healthy volunteers underwent right anterolateral impacts of 4.0, 7.6, 10.7, and 13.0 m/s2 peak acceleration, each with the head rotated to the left, then the head rotated to the right in a random order of impact severities. Bilateral electromyograms of the sternocleidomastoids, trapezii, and splenii capitis following impact were measured. Results At a peak acceleration of 13.0 m/s2, with the head rotated to the right, the right trapezius generated 61% of its maximal voluntary contraction electromyogram (MVC EMG), while all other muscles generated 31% or less of this variable (31% for the left trapezius, 13% for the right spleinus. capitis, and 16% for the left splenius capitis). The sternocleidomastoids muscles also tended to show an asymmetric EMG response, with the left sternocleidomastoid (the one responsible for head rotation to the right) generating a higher percentage (26%) of its MVC EMG than the left sternocleidomastoid (4%) (p < 0.05). When the head is rotated to the left, under these same conditions, the results are reversed even though the impact direction remains right anterolateral. Conclusion The EMG response to a right anterolateral impact is highly dependent on the head position. The sternocleidomastoid responsible for the direction of head rotation and the trapezius ipsilateral to the direction of head rotation generate the most EMG activity. PMID:15927056

  14. When range of motion is not enough: towards an evidence-based approach to medico-legal reporting in whiplash injury.

    Whiplash injury medico-legal reporting has traditionally been focused upon identifying restrictions in range of motion and identifying the presence of tender areas in the cervical spine in an effort both to diagnose the condition and to offer a prognosis. There have been considerable advances in this field over the last decade however that calls into question such a diminutive approach. This paper reviews the contemporary evidence base for the medico-legal assessment of whiplash injury and identifies a body of literature that strongly implicates a Claimant's physiological and psychological stress response as a key medico-legal marker in predicting prognosis following whiplash injury.

    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.

    Posttraumatic stress (PTSS) and generalized anxiety symptoms (GAS) may ensue following trauma. While they are now thought to represent different psychopathological entities, it is not clear whether both GAS and PTSS show a dose-response to trauma exposure. The current study aimed to address this gap in knowledge and to investigate the moderating role of subjects' demographics in the exposure-outcome associations. The sample included 249 civilian adults, assessed during the 2014 Israel-Gaza military conflict. The survey probed demographic information, trauma exposure, and symptoms. PTSS but not GAS was associated with exposure severity. Women were at higher risk for both PTSS and GAS than men. In addition, several demographic variables were only associated with PTSS levels. PTSS dose-response effect was moderated by education. These findings are in line with emerging neurobiological and cognitive research, suggesting that although PTSS and GAS have shared risk factors they represent two different psychopathological entities. Clinical and theoretical implications are discussed. PMID:26343559

  20. 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

    It is well known that injuries and deaths due to penetrating projectiles have become a national and an international epidemic in Western society. The application of biomedical engineering to solve day-to-day problems has produced considerable advances in safety and mitigation/prevention of trauma. The study of penetrating trauma has been largely in the military domain where war-time specific applications were advanced with the use of high-velocity weapons. With the velocity and weapon caliber in the civilian population at half or less compared with the military counterpart, wound ballistics is a largely different problem in today's trauma centers. The principal goal of the study of penetrating injuries in the civilian population is secondary prevention and optimized emergency care after occurrence. A thorough understanding of the dynamic biomechanics of penetrating injuries quantifies missile type, caliber, and velocity to hard and soft tissue damage. Such information leads to a comprehensive assessment of the acute and long-term treatment of patients with penetrating injuries. A review of the relevant military research applied to the civilian domain and presentation of new technology in the biomechanical study of these injuries offer foundation to this field. Relevant issues addressed in this review article include introduction of the military literature, the need for secondary prevention, environmental factors including projectile velocity and design, experimental studies with biological tissues and physical models, and mathematical simulations and analyses. Areas of advancement are identified that enables the pursuit of biomechanics research in order to arrive at better secondary prevention strategies. PMID:9719858

    Traumatic brain injury (TBI) was the signature injury in both the Iraq and Afghan wars and the magnitude of its importance in the civilian setting is finally being recognized. Given the scope of the problem, new therapies are needed across the continuum of care. Few therapies have been shown to be successful. In severe TBI, current guidelines-based acute therapies are focused on the reduction of intracranial hypertension and optimization of cerebral perfusion. One factor considered important to the failure of drug development and translation in TBI relates to the recognition that TBI is extremely heterogeneous and presents with multiple phenotypes even within the category of severe injury. To address this possibility and attempt to bring the most promising therapies to clinical trials, we developed Operation Brain Trauma Therapy (OBTT), a multicenter, pre-clinical drug screening consortium for acute therapies in severe TBI. OBTT was developed to include a spectrum of established TBI models at experienced centers and assess the effect of promising therapies on both conventional outcomes and serum biomarker levels. In this review, we outline the approach to TBI modeling, evaluation of therapies, drug selection, and biomarker assessments for OBTT, and provide a framework for reports in this issue on the first five therapies evaluated by the consortium.

    Acute malocclusion can result from disturbances in the maxillary/mandibular tooth relationship. These alterations in the occlusal position can result from high fillings, sinus problems, abscesses, periodontal disease, and moving or erupting teeth. Conditions seen less frequently include acute malocclusions secondary to an event (such as trauma) that make a stable dental relationship an unstable one. Patients can demonstrate any of a number of clinical conditions that interfere with their comfort and ability to function. This article provides information on some of the less familiar causes of acute malocclusion. PMID:16689064

    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.

    STUDY DESIGN Non-systematic review of cervical spine lesions in whiplash-associated disorders (WAD). OBJECTIVE To describe whiplash injury models in terms of basic and clinical science, to summarize what can and cannot be explained by injury models, and to highlight future research areas to better understand the role of tissue damage in WAD. SUMMARY OF BACKGROUND DATA The frequent lack of detectable tissue damage has raised questions about whether tissue damage is necessary for WAD and what role it plays in the clinical context of WAD. METHODS Non-systematic review. RESULTS Lesions of various tissues have been documented by numerous investigations conducted in animals, cadavers, healthy volunteers and patients. Most lesions are undetected by imaging techniques. For zygapophysial (facet) joints, lesions have been predicted by bioengineering studies and validated through animal studies; for zygapophysial joint pain, a valid diagnostic test and a proven treatment are available. Lesions of dorsal root ganglia, discs, ligaments, muscles and vertebral artery have been documented in biomechanical and autopsy studies, but no valid diagnostic test is available to assess their clinical relevance. The proportion of WAD patients in whom a persistent lesion is the major determinant of ongoing symptoms is unknown. Psychosocial factors, stress reactions and generalized hyperalgesia have also been shown to predict WAD outcomes. CONCLUSION There is evidence supporting a lesion-based model in WAD. Lack of macroscopically identifiable tissue damage does not rule out the presence of painful lesions. The best available evidence concerns zygapophysial joint pain. The clinical relevance of other lesions needs to be addressed by future research. PMID:22020601

  6. A Comparison of Biomechanical Mechanisms of Whiplash Injury from Rear Impacts

    Several hypotheses have been proposed to explain the mechanism of injury in whiplash including, pressure on nerve root ganglia, stretching of facet capsules, or damage to facet articular cartilage. These injury mechanisms have not been directly compared in the same study. A comparison could provide insight into the most likely mechanism of whiplash injury. Twenty eight volunteers underwent rear impacts with head and chest acceleration data collected. The same apparatus was used to test 11 cervico-thoracic human cadaveric spines with an instrumented headform attached. Head acceleration, individual vertebral kinematics from high speed video, local nerve root pressure, and facet joint contact pressures were collected during impacts. Each specimen was tested first at an impact acceleration similar to that of volunteers, who reported minimal or no symptoms after the test, then at double the acceleration. Head X (forward) and Z (upward) accelerations of cadaveric specimens were very similar in time sequence and magnitude to those of unprepared volunteers. Pressure around the lower cervical nerve roots ranged from 2.7kPa to 10kPa, and occurred generally after chest but before peak head acceleration. Facets at C4–5 and C5–6 had the highest probability (64% and 71% respectively) of pinching. Neither pressure rise nor pinching changed significantly with increased acceleration. Vertebral intersegmental extension rotations (4°–9.5°) and posterior translations (3.7–8.9 mm) peaked near maximum head excursion into the head restraint, at the time of peak head acceleration. Vertebral shear translations showed the largest (and only significant) increases with increased impact acceleration. This data implies that facet shearing was most sensitive to the increased acceleration in this experiment and may be a primary mechanism of cervical spine injury in rear impacts. PMID:12941237

    Rural trauma is a major problem in the United States. Up to 70 percent of trauma fatalities occur in rural areas, even though 70 percent of the population live in urban areas. Over the past 3 decades, numerous studies have defined the concept of preventable trauma death in both rural and urban populations. With the development of a regional trauma care system in Oregon, preventable trauma mortality should decrease. An effort was made to improve the quality of trauma care in Clatsop County, Oregon, a community of 30,000 people with 2 small rural hospitals. To obtain this goal, four steps were taken: (1) physician and nurse education was improved, (2) trauma protocols promoting prompt resuscitation and stabilization of patients were established, (3) regular trauma case reviews were conducted, and (4) emergency medical technician and prehospital management were coordinated. This study reviews the trail from sporadic, uncoordinated rural trauma care to the designation process. PMID:2712202

    In this study we examined the relationship between posttrauma pathology and the level of articulation (complexity) in rape narratives recounted by victims shortly after the assault. Degree of articulation was operationalized as the reading level of the narrative as determined by a computer program. Shortly after the trauma, reading level was correlated with severity of anxiety but not with posttraumatic stress disorder (PTSD) symptoms. Degree of the narrative articulation shortly after the trauma, however, was related to severity of later PTSD. These results are consistent with the hypothesis that the less developed trauma narratives hinder recovery from trauma. PMID:9565923

    Violently shaking a baby leads to clinical presentations ranging from seizures to cardiopulmonary arrest. The main injuries sustained are retinal hemorrhages, subdural hemorrhages, and sometimes fractures and spine injury. It is important to have a global view of the injuries sustained by the infant to correctly discuss the biomechanical aspects of abusive head trauma. Recent works based on finite element models have shown that whiplash-shaking alone is enough to generate vitreo-retinal traction leading to retinal hemorrhage and to cause the rupture of bridging veins leading to subdural hemorrhage. We will review the main papers dealing with the mechanisms of shaken baby syndrome and present the most relevant hypothesis concerning the biomechanical aspects of injuries related to shaken baby syndrome.

    Historical perceptions regarding the severity of traumatic spinal cord injury has led to considerable disparity in triage to tertiary care centers. This article retrospectively reviews a large regional trauma database to analyze whether the diagnosis of spinal trauma affected patient transfer timing and patterns. The Pennsylvania Trauma database was retrospectively reviewed. All acute trauma patient entries for level I and II centers were categorized for diagnosis, mechanism, and location of injury, analyzing transportation modality and its influence on time of arrival. A total of 1162 trauma patients were identified (1014 blunt injuries, 135 penetrating injuries and 12 other) with a mean transport time of 3.9 hours and a majority of patients arriving within 7 hours (>75%). Spine trauma patients had the longest mean arrival time (5.2 hours) compared to blunt trauma (4.2 hours), cranial neurologic injuries (4.35 hours), and penetrating injuries (2.13 hours, p<0.0001). There was a statistically significant correlation between earlier arrivals and both cranial trauma (p=0.0085) and penetrating trauma (p<0.0001). The fastest modality was a fire rescue (0.93 hours) or police (0.63 hours) vehicle with Philadelphia County (1.1 hour) having the quickest arrival times. Most trauma patients arrived to a specialty center within 7 hours of injury. However subsets analysis revealed that spine trauma patients had the greatest transit times. Present research trials for spinal cord injuries suggest earlier intervention may lead to improved recovery. Therefore, it is important to focus on improvement of the transportation triage system for traumatic spinal patients. PMID:24932590

    Background The return of heparinized shed blood in trauma/hemorrhagic shock (T/HS) models remains controversial due to potential anti-inflammatory properties. Although ubiquitous as an anticoagulant, heparin is ineffective on cellular coagulation as an antithrombotic agent. Therefore, we hypothesized that returning heparinized shed blood would paradoxically enhance ALI following T/HS due to the infusion of activated platelets. Methods Sprague-Dawley rats, anesthetized with pentobarbital, underwent laparotomy and hemorrhage-induced shock (MAP of 30 mmHg × 45 min). Animals were resuscitated with a combination of normal saline (NS) and returned shed blood. Shed blood was collected in either 80U/kg of heparin, 800U/kgof heparin, citrate, or diluted 1:8 with NS. An additional group of animals were pretreated with a platelet P2Y12 receptor antagonist (clopidogrel) prior to T/HS. BAL, lung MPO assays, pulmonary immunofluorescence, and blood smears were conducted. Results BAL protein increased in animals resuscitated with heparinized shed blood (p<0.0001). Blood smears and platelet function assays revealed platelet aggregates and increased platelet activation. Animals pretreated with a platelet P2Y12 receptor antagonist were protected from post-injury ALI (p<0.0001). Animals with return of shed blood had increased pulmonary PMN sequestration (p<0.0001). Pulmonary immunofluorescence demonstrated microthrombi only in the T/HS group receiving heparinized shed blood (p<0.0001). Conclusion The return of heparinized shed blood functions as a “second-hit” to enhance ALI, with activated platelets propagating microthrombi and pulmonary PMN recruitment. PMID:21841533

    Objective: To identify patterns of errors contributing to inpatient trauma deaths. Methods: All inpatient trauma deaths at a high-volume level I trauma center from 1996 to 2004 inclusive were audited. Data were collected with daily trauma registry chart abstraction, weekly morbidity and mortality reports, hospital quality assurance reports, and annual trauma registry analyses of risk of death using TRISS and HARM methodology. Deaths that met criteria for low to medium probability of mortality or those with quality of care concerns were analyzed for errors and then subjected to 3-stage peer review at weekly departmental, monthly hospital, and annual regional forums. Patterns of errors were constructed from the compiled longitudinal data. Results: In 9 years, there were 44,401 trauma patient admissions and 2594 deaths (5.8%), of which 601 met low to medium mortality risks. Sixty-four patients (0.14% admissions, 2.47% deaths) had recognized errors in care that contributed to their death. Important error patterns included: failure to successfully intubate, secure or protect an airway (16%), delayed operative or angiographic control of acute abdominal/pelvic hemorrhage (16%), delayed intervention for ongoing intrathoracic hemorrhage (9%), inadequate DVT or gastrointestinal prophylaxis (9%), lengthy initial operative procedures rather than damage control surgery in unstable patients (8%), over-resuscitation with fluids (5%), and complications of feeding tubes (5%). Resulting data-directed institutional and regional trauma system policy changes have demonstrably reduced the incidence of associated error-related deaths. Conclusions: Preventable deaths will occur even in mature trauma systems. This review has identified error patterns that are likely common in all trauma systems, and for which policy interventions can be effectively targeted. PMID:16926563

    The purpose of this study was to determine magnetic resonance imaging (MRI) findings relevant to synovial injury of the shoulder in patients with and without acute shoulder trauma. Three hundred and nine consecutive shoulder MRI studies (185-male, 124-female, 50 ± 15 years old) were retrospectively evaluated for findings suggestive of synovial injury including rupture and/or diverticulum of the joint capsule, bursa, and biceps tendon sheath (BTS), ganglion/synovial cyst, geyser phenomenon, and sequel of previous shoulder dislocation (Hill-Sachs deformity). Patients with one or more of these findings were included in the MR-positive group, whereas the remaining subjects were used as MR negatives. Based on their medical records, patients were also divided into trauma and non-trauma groups, and statistical analysis was performed to evaluate the association between the aforementioned MRI findings and history of shoulder trauma. Fifty-six patients were included in the MR-positive group and 253 in the MR-negative group. In MR-positive group, the incidence of capsular rupture (CR) and subacromial/subdeltoid (SASD) bursal rupture was higher in trauma patients, whereas the incidence of BTS diverticulum and ganglion cyst was higher in subjects without trauma. Significant association was found between the history of acute trauma and CR, SASD bursal rupture, BTS rupture, and Hill-Sachs deformity. In shoulder MR examination, presence of CR and/or SASD bursal rupture is strongly suggestive of acute shoulder trauma. In addition, BTS rupture and Hill-Sachs deformity are more prevalent in patients with acute shoulder trauma. The presence of these features should alert MRI readers to assess for additional trauma-related internal derangements, if a respective history has not been provided. PMID:21735271

    Minor trauma to the head or neck is occasionally followed by severe chronic headaches. We have evaluated 35 adults (27 women, 8 men) with no prior history of headaches, who developed recurrent episodic attacks typical of common or classic migraine following minor head or neck injuries ("post-traumatic migraine"-PTM). The median age of these patients was 38 years (range 17 to 63 years), which is older than the usual age at onset of idiopathic migraine. The trauma was relatively minor: 14 patients experienced head trauma with brief loss of consciousness, 14 patients sustained head trauma without loss of consciousness, and 7 patients had a "whiplash" neck injury with no documented head trauma. Headaches began immediately or within the first few days after the injury. PTM typically recurred several times per week and was often incapacitating. The patients had been unsuccessfully treated by other physicians, and there was a median delay of 4 months (range 1 to 30 months) before the diagnosis of PTM was suspected. The response to prophylactic anti-migraine medication (propranolol or amitriptyline used alone or in combination) was gratifying, with 21 of 30 adequately treated patients (70%) reporting dramatic reduction in the frequency and severity of their headaches. Improvement was noted in 18 of the 23 patients (78%) who were still involved in litigation at the time of treatment. The neurologic literature has placed excessive emphasis on compensation neurosis and psychological factors in the etiology of chronic headaches after minor trauma. Physicians must be aware of PTM, as it is both common and treatable. PMID:1774160

    The word 'trauma' describes the disease entity resulting from physical injury. Trauma is one of the leading causes of death worldwide and deaths due to injury look set to increase. As early as the 1970s, it became evident that centralisation of resources and expertise could reduce the mortality rate from serious injury and that organisation of trauma care delivery into formal systems could improve outcome further. Internationally, trauma systems have evolved in various forms, with widespread reports of mortality and functional outcome benefits when major trauma management is delivered in this way. The management of major trauma in England is currently undergoing significant change. The London Trauma System began operating in April 2010 and others throughout England became operational this year. Similar systems exist internationally and continue to be developed. Anaesthetists have been and continue to be involved with all levels of trauma care delivery, from the provision of pre-hospital trauma and retrieval teams, through to chronic pain management and rehabilitation of patients back into society. This review examines the international development of major trauma care delivery and the components of a modern trauma system. PMID:23210554

    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.

    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. PMID:6226097

    Multiple system atrophy (MSA) is characterized clinically by parkinsonism, cerebellar, autonomic, and corticospinal features of variable severity. When the presentation is only parkinsonism, the disease might be difficult to differentiate from Parkinson's disease (PD). We present a case of an 80-year-old man with previous diagnosis of PD. One year after the diagnosis, he had a whiplash cervical trauma due to a tricycle accident caused by a hole in the road. This low-energy trauma caused an unstable C4-C5 cervical fracture with spinal cord injury, which required surgical decompression and stabilization. Neurological examination showed marked postural instability, no rest and postural tremor, finger tapping slowed on the right, spastic tetraparesis (ASIA D) - predominantly on the left side, brisk deep tendon reflexes in the upper and lower extremities, and bilateral extensor plantar response. He also presented with vertical gaze restriction, mild hypometria in horizontal saccades, moderate dysphagia, and dysphonia. As atypical parkinsonism was suspected, he underwent an MRI that revealed conjunction of findings suggestive of parkinsonian-type MSA. In our case, we hypothesize that the loss of postural reflexes, as an early manifestation of MSA, did not allow the patient to have an effective reaction response to a low-energy trauma, resulting in a more severe injury. With this case report, we speculate that the severe spinal lesions caused by minor accidents can be an early sign of postural instability, which may lead to clinical suspicion of neurodegenerative disorder manifested by postural reflexes impairment.

    Blunt trauma to the chest resulting in coronary thrombosis and ST elevation myocardial infarction (STEMI) is a rare but well-described occurrence in adults. Angiography in such cases has generally disclosed complete epicardial coronary occlusion with thrombus, indistinguishable from the findings commonly found in spontaneous plaque rupture due to atherosclerotic disease. In all previously reported cases in which coronary interrogation with intravascular ultrasound (IVUS) was performed in association with acute revascularization, coronary artery dissection was implicated as the etiology of coronary thrombosis. We present the first case report of blunt trauma-associated coronary thrombosis without underlying atherosclerosis or coronary dissection, as documented by IVUS imaging. PMID:27006836

    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

    Patients with whiplash associated disorders (WAD) have shown less accuracy in trajectory head motion compared to asymptomatic controls, which comply with clinical observations. The aim of this study was to investigate whether a trajectory head movement task can differ between WAD patients, chronic non-traumatic neck pain (CNP) patients and asymptomatic controls. Study groups included subjects with WAD (n = 35) with persistent neck pain after a car accident, CNP (n = 45), and asymptomatic controls (n = 48). Head motion was recorded from an unsupported standing position using a 3D Fastrak device. A laser pointer was attached to the head and by moving the head the subjects were asked to trace a figure of eight displayed on the wall at three different paces (slow, moderate and fast). The motion signal was decomposed into 1 Hz frequency bands and angular velocity (deg/s) within each frequency band was calculated. Significantly higher angular RMS velocity was found in the WAD group compared to the two other groups for the slow paced test (3-4 and 4-5 Hz frequency bands) and the moderate paced test (3-4 Hz frequency band) indicating irregular and uncoordinated movements. Angular RMS velocity was associated with pain and dizziness, but only with severe symptom levels. In conclusion, irregular head movements during a complex task were found in the WAD group, indicating altered central sensorimotor processing. The irregularities were found within frequency levels observable to clinicians. PMID:19820919

    The neural pathogenic mechanisms involved in mediating chronic pain and whiplash associated disorders (WAD) after rear impact car collisions are largely unknown. This study's first objective was to compare resting state regional cerebral blood flow (rCBF) by means of positron emission tomography with (15)O labelled water in 21 WAD patients with 18 healthy, pain-free controls. A second objective was to investigate the relations between brain areas with altered rCBF to pain experience, somatic symptoms, posttraumatic stress symptoms and personality traits in the patient group. Patients had heightened resting rCBF bilaterally in the posterior parahippocampal and the posterior cingulate gyri, in the right thalamus and the right medial prefrontal gyrus as well as lowered tempero-occipital blood flow compared with healthy controls. The altered rCBF in the patient group was correlated to neck disability ratings. We thus suggest an involvement of the posterior cingulate, parahippocampal and medial prefrontal gyri in WAD and speculate that alterations in the resting state are linked to an increased self-relevant evaluation of pain and stress.

    Acute lung injury (ALI) is one of the most serious complications in traumatic patients and is an important part of multiple organ dysfunction syndrome (MODS). Recombinant human brain natriuretic peptide (rhBNP) is a peptide with a wide range of biological activity. In this study, we investigated local changes in oxidative stress and the NF-κB-dependent matrix metalloproteinase-9 (MMP-9) pathway in rats with trauma/haemorrhagic shock (TH/S)-induced ALI and evaluated the effects of pretreatment with rhBNP. Forty-eight rats were randomly divided into four groups: sham operation group, model group, low-dosage rhBNP group and high-dosage rhBNP group (n = 12 for each group). Oxidative stress and MPO activity were measured by ELISA kits. MMP-9 activity was detected by zymography analysis. NF-κB activity was determined using Western blot assay. With rhBNP pretreatment, TH/S-induced protein leakage, increased MPO activity, lipid peroxidation and metalloproteinase (MMP)-9 activity were inhibited. Activation of antioxidative enzymes was reversed. The phosphorylation of NF-κB and the degradation of its inhibitor IκB were suppressed. The results suggested that the protection mechanism of rhBNP is possibly mediated through upregulation of anti-oxidative enzymes and inhibition of NF-κB activation. More studies are needed to further evaluate whether rhBNP is a suitable candidate as an effective inhaling drug to reduce the incidence of TH/S-induced ALI. PMID:26852688

    Transfusion and resuscitation practices in trauma have undergone a sea change over the past decade. New understanding of transfusion physiology and experiences in military trauma over the last decade has identified key factors taken as challenges in trauma. The most important challenge remains acute traumatic coagulopathy (ATC) which sets in early after a trauma and spirals the patient into shock and continued bleeding. World wide trauma is the leading cause of mortality. More than 6 million deaths occur due to trauma out of which 20% are due to uncontrollable bleeding. Out of the hospital admissions in trauma 20% develop coagulopathy. Mortality is three to four times higher in a patient with coagulopathy and thus prevention and correction of coagulopathy is the central goal of the management of hemorrhagic shock in trauma. Damage control resuscitation (DCR), a strategy combining the techniques of permissive hypotension, hemostatic resuscitation and damage control surgery has been widely adopted as the preferred method of resuscitation in patients with haemorrhagic shock. The over-riding goals of DCR are to mitigate metabolic acidosis, hypothermia and coagulopathy, This article looks at the importance of acute traumatic coagulopathy, its etiology, diagnosis, effects and resuscitation strategies to prevent it and to see the background behind this shift.

    Blunt thoracic trauma represents a significant portion of trauma admissions to hospitals in the United States. These injuries are encountered by physicians in many specialities such as emergency medicine, pediatrics, general surgery and thoracic surgery. Accurate diagnosis and treatment improves the chances of favorable outcomes and it is desirable for all treating physicians to have current knowledge of all aspects of blunt thoracic trauma. Cardiothoracic surgeons often treat the most severe forms of blunt thoracic injuries and we review the aspects of blunt thoracic trauma that are pertinent to the practicing cardiothoracic surgeon.

    The second, internet-based multicenter study (MCSII) of the Spine Study Group of the German Association of Trauma Surgery (Deutsche Gesellschaft für Unfallchirurgie) is a representative patient collection of acute traumatic thoracolumbar (T1–L5) injuries. The MCSII results are an update of those obtained with the first multicenter study (MCSI) more than a decade ago. The aim of the study was to assess and bring into focus: the (1) epidemiologic data, (2) surgical and radiological outcome, and (3) 2-year follow-up (FU) results of these injuries. According to the Magerl/AO classification, there were 424 (57.8%) compression fractures (A type), 178 (24.3%) distractions injuries (B type), and 131 (17.9%) rotational injuries (C type). B and C type injuries carried a higher risk for neurological deficits, concomitant injuries, and multiple vertebral fractures. The level of injury was located at the thoracolumbar junction (T11–L2) in 67.0% of the case. 380 (51.8%) patients were operated on by posterior stabilization and instrumentation alone (POSTERIOR), 34 (4.6%) had an anterior procedure (ANTERIOR), and 319 (43.5%) patients were treated with combined posteroanterior surgery (COMBINED). 65% of patients with thoracic (T1–T10) and 57% with lumbar spinal (L3–L5) injuries were treated with a single posterior approach (POSTERIOR). 47% of the patients with thoracolumbar junction (T11–L2) injuries were either operated from posterior or with a combined posterior–anterior surgery (COMBINED) each. Short angular stable implant systems have replaced conventional non-angular stable instrumentation systems to a large extent. The posttraumatic deformity was restored best with COMBINED surgery. T-spine injuries were accompanied by a higher number and more severe neurologic deficits than TL junction or L-spine injuries. At the same time T-spine injuries showed less potential for neurologic recovery especially in paraplegic (Frankel/AISA A) patients. 5% of all patients

    Study Design Best evidence synthesis. Objective To perform a best evidence synthesis on the course and prognostic factors for neck pain and its associated disorders in Grades I–III whiplash-associated disorders (WAD). Summary of Background Data Knowledge of the course of recovery of WAD guides expectations for recovery. Identifying prognostic factors assists in planning management and intervention strategies and effective compensation policies to decrease the burden of WAD. Methods The Bone and Joint Decade 2000–2010 Task Force on Neck Pain and its Associated Disorders (Neck Pain Task Force) conducted a critical review of the literature published between 1980 and 2006 to assemble the best evidence on neck pain and its associated disorders. Studies meeting criteria for scientific validity were included in a best evidence synthesis. Results We found 226 articles related to course and prognostic factors in neck pain and its associated disorders. After a critical review, 70 (31%) were accepted on scientific merit; 47 of these studies related to course and prognostic factors in WAD. The evidence suggests that approximately 50% of those with WAD will report neck pain symptoms 1 year after their injuries. Greater initial pain, more symptoms, and greater initial disability predicted slower recovery. Few factors related to the collision itself (for example, direction of the collision, headrest type) were prognostic; however, postinjury psychological factors such as passive coping style, depressed mood, and fear of movement were prognostic for slower or less complete recovery. There is also preliminary evidence that the prevailing compensation system is prognostic for recovery in WAD. Conclusion The Neck Pain Task Force undertook a best evidence synthesis to establish a baseline of the current best evidence on the course and prognosis for WAD. Recovery of WAD seems to be multifactorial.

    Fear and avoidance of activity may play a role in fostering disability in whiplash-associated disorders (WAD). This study examined the role of fear following WAD and assessed the effectiveness of three treatments targeting fear. People still symptomatic from WAD Grade I–II injuries approximately 3 months previously (n = 191) completed questionnaires (e.g., Neck Disability Index [NDI]) and were randomized to one of the treatments: (1) informational booklet (IB) describing WAD and the importance of resuming activities; (2) IB + didactic discussions (DD) with clinicians reinforcing the booklet; and (3) IB + imaginal and direct exposure desensitization (ET) to feared activities. DD and ET participants received three 2-hour treatment sessions. Absolute improvements in NDI were in predicted direction (ET = 14.7, DD = 11.9, IB = 9.9). ETs reported significantly less post-treatment pain severity, compared to the IB (M = 1.5 vs. 2.3, p < 0.001, d = 0.6) and DD (M = 1.5 vs. 2.0, p = 0.039, d = 0.6) groups. Reduction in fear was the most important predictor of improvement in NDI (β = 0.30, p < 0.001), followed by reductions in pain (β = 0.20, p = 0.003) and depression (β = 0.18, p = 0.004). The mediational analysis confirmed that fear reduction significantly mediated the effect of treatment group on outcome. Results highlight the importance of fear in individuals with subacute WAD, and suggest the importance of addressing fear, via exposure therapy and/or educational interventions, to improve function.

    The aetiology of chronic whiplash associated disorder (WAD) is unclear and the condition has been perceived both as a chronic pain disorder, based on the injury to the neck, and as a functional somatic disorder. Based on the hypothesis that chronic WAD should be perceived as a functional somatic syndrome, we compared the symptom profile of persons with chronic WAD with the profile of persons with a functional somatic disorder, and with the profile of persons with an organic pain disorder. A sample of 55,046 persons participating in a Norwegian population-based health study (HUNT 2) was divided into four study groups: chronic WAD, fibromyalgia, rheumatoid arthritis, and controls (none of these disorders). Symptoms were categorized as pain and stiffness, cardiopulmonary and gastrointestinal symptoms, and mental disorders. Odds ratios (ORs) with 95% confidence intervals (CIs) from logistic regression were used to compare the prevalence of symptoms among the groups. The chronic WAD group had a significantly higher prevalence of symptoms from all body parts, across organ systems and also mental symptoms, compared to the control group. The fibromyalgia group had an even higher prevalence of all symptoms, while the rheumatoid arthritis group showed an increase in the prevalence of particularly pain and stiffness symptoms and also a minor increase in the prevalence of other symptoms compared to the control group. We conclude that this study provide evidence in favour of the hypothesis that chronic WAD should be perceived as a functional somatic syndrome. Persons with chronic WAD had a symptom profile more similar to people with a functional somatic disorder than an organic pain disorder, consisting of a wide array of symptoms, not only predominantly pain symptoms.

    Study Design Best evidence synthesis. Objective To undertake a best evidence synthesis on the burden and determinants of whiplash-associated disorders (WAD) after traffic collisions. Study Design Summary of Background Data. Previous best evidence synthesis on WAD has noted a lack of evidence regarding incidence of and risk factors for WAD. Therefore there was a warrant of a reanalyze of this body of research. Methods A systematic search of Medline was conducted. The reviewers looked for studies on neck pain and its associated disorders published 1980 –2006. Each relevant study was independently and critically reviewed by rotating pairs of reviewers. Data from studies judged to have acceptable internal validity (scientifically admissible) were abstracted into evidence tables, and provide the body of the best evidence synthesis. Results The authors found 32 scientifically admissible studies related to the burden and determinants of WAD. In the Western world, visits to emergency rooms due to WAD have increased over the past 30 years. The annual cumulative incidence of WAD differed substantially between countries. They found that occupant seat position and collision impact direction were associated with WAD in one study. Eliminating insurance payments for pain and suffering were associated with a lower incidence of WAD injury claims in one study. Younger ages and being a female were both associated with filing claims or seeking care for WAD, although the evidence is not consistent. Preliminary evidence suggested that headrests/car seats, aimed to limiting head extension during rear-end collisions had a preventive effect on reporting WAD, especially in females. Conclusion WAD after traffic collisions affects many people. Despite many years of research, the evidence regarding risk factors for WAD is sparse but seems to include personal, societal, and environmental factors. More research including, well-defined studies with accurate denominators for calculating risk

    As one component of the Chinese medicine meridian system, the meridian sinew (Jingjin, (see text), tendino-musculo) is specially described as being for acupuncture treatment of the musculoskeletal system because of its dynamic attributes and tender point correlations. In recent decades, the therapeutic importance of the sinew meridian has become revalued in clinical application. Based on this theory, the authors have established therapeutic strategies of acupuncture treatment in Whiplash-Associated Disorders (WAD) by categorizing four types of neck symptom presentations. The advantage of this new system is to make it much easier for the clinician to find effective acupuncture points. This study attempts to prove the significance of the proposed therapeutic strategies by analyzing data collected from a clinical survey of various WAD using non-supervised statistical methods, such as correlation analysis, factor analysis, and cluster analysis. The clinical survey data have successfully verified discrete characteristics of four neck syndromes, based upon the range of motion (ROM) and tender point location findings. A summary of the relationships among the symptoms of the four neck syndromes has shown the correlation coefficient as having a statistical significance (P < 0.01 or P < 0.05), especially with regard to ROM. Furthermore, factor and cluster analyses resulted in a total of 11 categories of general symptoms, which implies syndrome factors are more related to the Liver, as originally described in classical theory. The hypothesis of meridian sinew syndromes in WAD is clearly supported by the statistical analysis of the clinical trials. This new discovery should be beneficial in improving therapeutic outcomes.

    Chronic whiplash is a debilitating condition characterized by increased sensitivity to painful stimuli, maladaptive illness beliefs, inappropriate attitudes, and movement dysfunctions. Previous work in people with chronic low back pain and chronic fatigue syndrome indicates that pain neurophysiology education is able to improve illness beliefs and attitudes as well as movement performance. This single-case study (A-B-C design) with six patients with chronic whiplash associated disorders (WAD) was aimed at examining whether education about the neurophysiology of pain is accompanied by changes in symptoms, daily functioning, pain beliefs, and behavior. Periods A and C represented assessment periods, while period B consisted of the intervention (pain neurophysiology education). Results showed a significant decrease in kinesiophobia (Tampa Scale for Kinesiophobia), the passive coping strategy of resting (Pain Coping Inventory), self-rated disability (Neck Disability Index), and photophobia (WAD Symptom List). At the same time, significantly increased pain pressure thresholds and improved pain-free movement performance (visual analog scale on Neck Extension Test and Brachial Plexus Provocation Test) were established. Although the current results need to be verified in a randomized, controlled trial, they suggest that education about the physiology of pain is able to increase pain thresholds and improve pain behavior and pain-free movement performance in patients with chronic WAD.

    Objective The aim of the study was to investigate the psychometric properties of a standardized assessment of pain drawing with regard to clinical signs of cervical spine nerve root involvement. Design This cross-sectional study included data collected in a randomized controlled study. Patients: Two hundred and sixteen patients with chronic (≥6 months) whiplash-associated disorders, grade 2 or 3, were included in this study. Methods The validity, sensitivity, and specificity of a standardized pain drawing assessment for determining nerve root involvement were analyzed, compared to the clinical assessment. In addition, we analyzed the interrater reliability with 50 pain drawings. Results Agreement was poor between the standardized pain drawing assessment and the clinical assessment (kappa =0.11, 95% CI: −0.03 to 0.20). Sensitivity was high (93%), but specificity was low (19%). Interrater reliability was good (kappa =0.64, 95% CI: 0.53 to 0.76). Conclusion: The standardized pain drawing assessment of nerve root involvement in chronic whiplash-associated disorders was not in agreement with the clinical assessment. Further research is warranted to optimize the utilization of a pain/discomfort drawing as a supportive instrument for identifying nerve involvement in cervical spinal injuries. PMID:27358576

    Vertigo and dizziness are common clinical manifestations after traffic accident-associated whiplash injury. Recently, Shinonaga et al. (2001) suggested that more than 80% of patients with whiplash injury complaining of these symptoms showed cerebrospinal (CSF) hypovolemia on radioisotope (RI) cisternography (111In-DTPA). However, neuro-otological studies to investigate the pathophysiological mechanisms underlying these symptoms have been insufficient. In the present study, patients complaining of these symptoms with CSF hypovolemia after traffic accidents were investigated with posturography and electronystagmography (ENG). Fourteen patients (4 men, 10 women; 24-52 yr) were examined with posturography and showed parameters (tracking distance & area) significantly (p<0.01) larger than those of healthy subjects. Among them, five cases (1 man, 4 women; 31-52 yr) were further investigated with ENG. The slow phase peak velocities of optokinetic nystagmus (OKN) and optokinetic-after nystagmus (OKAN) were significantly (p<0.01) reduced (62.64±6.9 SD deg/sec, 60.76±10.74 SD deg/sec, respectively) and frequencies of OKN were reduced (139.7±10.75 SD), while the ocular smooth pursuit was relatively preserved. Magnetic resonance images (sagittal view) of these five patients demonstrated the downward displacement of the cerebellar tonsils and flattening of the pons, which are characteristic features of CSF hypovolemia, called "brain sagging." Our results suggest that brain sagging due to CSF hypovolemia impairs vestibular and vestibulocerebellar functions, which may cause dizziness and vertigo. PMID:25957209

    Abstract: Background: Pain in trauma has a role similar to the double-edged sword. On the one hand, pain is a good indicator to determine the severity and type of injury. On the other hand, pain can induce sever complications and it may lead to further deterioration of the patient. Therefore, knowing how to manage pain in trauma patients is an important part of systemic approach in trauma. The aim of this manuscript is to provide information about pain management in trauma in the Emergency Room settings. Methods: In this review we searched among electronic and manual documents covering a 15-yr period between 2000 and 2016. Our electronic search included Pub Med, Google scholar, Web of Science, and Cochrane databases. We looked for articles in English and in peer-reviewed journals using the following keywords: acute pain management, trauma, emergency room and injury. Results: More than 3200 documents were identified. After screening based on the study inclusion criteria, 560 studies that had direct linkage to the study aim were considered for evaluation based World Health Organization (WHO) pain ladder chart. Conclusions: To provide adequate pain management in trauma patients require: adequate assessment of age-specific pharmacologic pain management; identification of adequate analgesic to relieve moderate to severe pain; cognizance of serious adverse effects of pain medications and weighting medications against their benefits, and regularly reassessing patients and reevaluating their pain management regimen. Patient-centered trauma care will also require having knowledge of barriers to pain management and discussing them with the patient and his/her family to identify solutions. PMID:27414816

    Introduction Pancreatic lesions are very infrequent after closed abdominal trauma (5% of cases) with a complication rate that affects 30–40% of patients, and a mortality rate that can reach 39%. In our experience, closed abdominal traumatisms occurring at typical popular horse-riding festivals in our region constitute a high risk of pancreatic trauma. The purpose of the present paper is to raise awareness about our experience in the diagnosis and treatment of pancreatic lesions secondary to closed abdominal traumatism. Presentation of case We present the clinical cases of two young patients who, after suffering blunt abdominal trauma secondary to the impact of a horse during the celebration of typical horse-riding festival, were diagnosed with pancreatic trauma type III. The treatment was surgical in both cases and consisted in performing a pancreaticogastric anastomosis with preservation of the distal pancreas and spleen. The postoperative period was uneventful and, at present, both patients are asymptomatic. Discussion Signs and symptoms caused by pancreatic lesion are unspecific and difficult to objectify. With some limitations CT is the imaging test of choice for diagnosis and staging in the acute phase. The Wirsung section is indication for surgical treatment. The most extended surgical procedure in these cases is the resection of pancreatic body, tail, and spleen. Conclusion The identification of a pancreatic injury after closed abdominal trauma requires a high suspicion based on the injury mechanism. A safer option may be the distal pancreatic preservation with pancreaticogastric anastomosis in grade III lesions with healthy pancreatic tissue. PMID:25744560

    Jejunal perforation is extremely rare in trauma especially without initial involvement of the abdomen. We present the case of a delayed jejunal perforation after thoracic trauma with no initial indication of abdominal trauma in a 55-year-old man who was admitted to our department after a road traffic accident. The patient sustained thoracic trauma with rib fractures of the left hemithorax and hemopneumothorax and a mild head injury. On the fourth day of his in-hospital stay, he complained of severe abdominal pain and signs of acute abdomen were observed. He underwent emergency laparotomy where a perforation of the jejunum near the ligament of Treitz was noticed and sutured. His postoperative recovery was uneventful. Physicians treating trauma should always have a high degree of suspicion regarding rare abdominal injuries, with delayed presentation, even if no abdominal involvement is noticed during the initial survey.

    The response of the primary care physician in the initial assessment and management of acute arterial injuries will often be the deciding factor in survival of life, limb or organ system. Most arterial emergencies occur as a result of trauma, disruption of vessel wall and/or occlusion of flow. The common clinical syndromes of acute arterial emergencies are injuries to and beyond the aorta, acute aortic dissection, ruptured aortic aneurysm, and thromboembolic occlusive arterial disease. The role of arteriography and the urgency of definitive surgical repair in acute arterial emergencies is summarized. PMID:21283323

    Clinicians now appreciate the full chain of tissue damage of the interconnecting muscles, tendons, ligaments and fascia: this compromised linkage from the skull through the suboccipital musculature to the cervical spine and anterior/posterior cervical muscles, from the check-rein ligaments and muscles extending from the skull and maxilla to the mandible, from the suprahyoid musculature connecting the mandible through to the hyoid bone, from the hyoid through the infrahyoid to the supporting shoulder girdle, all contribute to damaged interconnecting matrices. Consequently, unresolved tissue damage in any of this linkage becomes mutually provocative during function to any part of the linkage. Diagnostics, therefore, must necessarily include examination of this total linkage; similarly, eventual treatment protocols must resolve tissue damage in all of this interconnecting linkage if treatment is to be successful beyond palliative applications. The influence of an angular component in any such trauma must be emphasized; force vectors then attack the craniomandibular/temporo-mandibular/cervical complex where it is most vulnerable, at the most restrictive parameters of functional mobility. Thus, the angular component brings an exponential increase in tissue damage potential to all of the craniomandibular/temporomandibular/cervical complex. Finally, if we are to treat the occlusion of these victims intelligently, we must understand the effects of this trauma on the 'whole body', and not just focus singularly on the restoration or the malocclusion or the TMJoint problem. There are lessons to be learned from this acute trauma which provide valuable insights into the diagnosis of chronic pain patients. If these victims do not come to us for help immediately following the acute trauma episode, but arrive in our offices months or years later, our clinical examinations must include head and neck mobility or functional restrictions, observations of the patients' gait, other

    Study Design Single-center prospective longitudinal study Objective To study the 1) temporal development of muscle fatty infiltrates (MFI) in the cervical multifidii following whiplash, 2) differences in multifidii MFI between those who recover or report milder pain related disability from those who report moderate/severe symptoms at 3 months, and 3) predictive value of multifidii MFI outcomes. Summary of Background Data The temporal development of MFI on conventional MRI has been shown to be associated with specific aspects of pain and psychological factors. The replication of such findings has yet to be explored longitudinally. Methods 36 subjects with whiplash injury were enrolled at < 1-week post-injury and classified at 3-months using percentage scores on the Neck Disability Index as recovered/mild (0–28%) or severe (≥ 30%). A fat/water MRI measure, patient self-report of pain related disability and post-traumatic stress were collected at <1-week, 2-weeks and 3-months post-injury. The effects of time and group (per NDI) and the interaction of time by group on MFI were determined. Receiver operating characteristic curve (ROC) analysis was used to determine a cut-point for MFI at 2 weeks to predict outcome at 3 months. Results There was no difference in MFI across groups at enrolment. MFI values were significantly higher in the severe group when compared to the recovered/mild group at 2-weeks and 3-months.The ROC analysis indicated that MFI levels of 20.5% or above resulted in a sensitivity of 87.5% and a specificity of 92.9% for predicting outcome at 3 months. Conclusions Consistent with previous evidence, muscle degeneration occurs soon after injury but only in those patients with poor functional recovery. This study provides further evidence that 1) multifidii MFI occurs in tandem with known predictive risk factors (older age, pain-related disability, and post-traumatic stress) and that 2) routine imaging protocols may need to be reconsidered in the vast

    The development of a strong trauma program is clearly one of the most important facets of successful business development. Several recent publications have demonstrated that well run trauma services can generate significant profits for both the hospital and the surgeons involved. There are many aspects to this task that require constant attention and insight. Top notch patient care, efficiency, and cost-effective resource utilization are all important components that must be addressed while providing adequate physician compensation within the bounds of hospital financial constraints and the encompassing legal issues. Each situation is different but many of the components are universal. This chapter addresses all aspects of trauma program development to provide the graduating fellow with the tools to create a new trauma program or improve an existing program in order to provide the best patient care while optimizing financial reward and improving care efficiency.

    The impact of traumatic injuries on modern society in terms of morbidity, mortality, and economic cost is enormous. Studies have shown that both advanced life support skills and rapid stabilization and transport of the trauma victim have a beneficial effect on the patient's ultimate outcome. The Basic Trauma Life Support (BTLS) course was designed to provide pre-hospital care providers with the skills necessary to provide a thorough assessment, initial resuscitation, and rapid transportation of the trauma victim. Early studies suggest that the material is easily learned by prehospital care providers and that the on-scene time for trauma cases is reduced following training in BTLS. More widespread training in BTLS may have a significant effect on the mortality and morbidity associated with traumatic injuries. PMID:3662184

    "Shaken baby syndrome" is a term often used by the physicians and public to describe abusive trauma inflicted on infants and young children. Advances in the understanding of the mechanisms and the associated clinical spectrum of injury has lead us to modify our terminology and address it as "abusive trauma" (AT). Pediatric abusive head trauma is defined as an injury to the skull or intracranial contents of an infant or a young child (< 5 y age) due to inflicted blunt impact and/or violent shaking. This chapter focuses on the imaging aspects of childhood abusive trauma along with a brief description of the mechanism and pathophysiology of abusive injury. The diagnosis of AT is not always obvious, and abusive injuries in many infants may remain unrecognized. Pediatricians should be cognizant of AT since pediatricians play a crucial role in the diagnosis, management and prevention of AT. PMID:26882906

    INTRODUCTION Massive transfusion protocol (MTP) is increasingly used in civilian trauma cases to achieve better haemostatic resuscitation in patients requiring massive blood transfusions (MTs), with improved survival outcomes. However, in non-trauma patients, evidence for MTP is lacking. This study aims to assess the outcomes of a newly established MTP in a civilian setting, for both trauma and non-trauma patients, in an acute surgical care unit. METHODS A retrospective cohort analysis was performed on 46 patients for whom MTP was activated in Changi General Hospital, Singapore. The patients were categorised into trauma and non-trauma groups. Assessment of Blood Consumption (ABC) score was used to identify MTP trauma patients and analyse over-activation rates. RESULTS Only 39.1% of all cases with MTP activation eventually received MTs; 39.8% of the MTs were for non-trauma patients. Mean fresh frozen plasma to packed red blood cells (pRBC) ratio achieved with MTP was 0.741, while mean platelet to pRBC ratio was 0.213. The 24-hour mortality rate for all patients who received an MT upon MTP activation was 33.3% (trauma vs. non-trauma group: 45.5% vs. 14.3%). The ABC scoring system used for trauma patients had a sensitivity and specificity of 81.8% and 41.2%, respectively. CONCLUSION MTP may be used for both trauma and non-trauma patients in acute care surgery. Scoring systems to predict the need for an MT, improved compliance to predefined transfusion ratios and regular reviews of the MTP are necessary to optimise MTPs and to improve the outcomes of patients receiving MTs.

    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.

    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.

    For many years, researchers involved in automotive industry and forensic medicine, as well as insurance companies have shown great interest in the issues of etiology and prevention of cervical spine distortion. The etiopathogenesis of whiplash-associated disorders (WADs) remains controversial and its morphological determinants have not been explicitly determined to date. The subjective nature of complaints causes great difficulties in objective assessment of the consequences of acceleration-deceleration injuries and in verification of compensation claims. The objective of the study was to present biomechanical relationships and circumstances accompanying WADs using population-based studies, statistical data of insurance companies and analysis of recordings of event data recorders installed by vehicle producers. The knowledge of technical aspects of WAD circumstances should facilitate medical assessment of the above-mentioned consequences. PMID:24261258

    In Western Europe the most frequent cause of multiple injuries is blunt trauma. Only few of us have experience with penetrating trauma, without exception far less than in the USA or South-Africa. In Rotterdam, the Erasmus Medical Centre is a level I trauma centre, situated directly in the town centre. All penetrating traumas are directly presented to our emergency department by a well organized ambulance service supported by a mobile medical team if necessary. The delay with scoop and run principles is very short for these cases, resulting in severely injured reaching the hospital alive in increasing frequency. Although the basic principles of trauma care according to the guidelines of the Advanced Trauma Life Support (ATLS) (1-2) are the same for blunt and penetrating trauma with regard to priorities, diagnostics and primary therapy, there are some pitfalls in the strategy of management in penetrating trauma one should be aware of. Simple algorithms can be helpful, especially in case of limited experience (3). In case of life-saving procedures, the principles of Damage Control Surgery (DCS) must be followed (4-5). This approach is somewhat different from "traditional" surgical treatment. In the Ist phase prompt interventions by emergency thoracotomy and laparotomy are carried out, with only two goals to achieve: surgical control of haemorrhage and contamination. After temporary life-saving procedures, the 2nd phase is characterized by intensive care treatment, dealing with hypothermia, metabolic acidosis and clotting disturbances. Finally in the 3rd phase, within 6-24 hours, definitive surgical care takes place. In this overview, penetrating injuries of neck, thorax, abdomen and extremities will be outlined. Penetrating cranial injuries, as a neurosurgical emergency with poor prognosis, are not discussed. History and physical examination remain the corner stones of good medical praxis.

    The classification of liver injuries is important for clinical practice, clinical research and quality assurance activities. The Organ Injury Scaling (OIS) Committee of the American Association for the Surgery of Trauma proposed the OIS for liver trauma in 1989. The purpose ofthe present study was to apply this scale to a cohort ofliver trauma patients managed at a single Canadian trauma centre from January 1987 to June 1992.170 study patients were identified and reviewed. The mean age was 30, with 69% male and a mean ISS of 33.90% had a blunt mechanism ofinjury. The 170 patients were categorized into the 60IS grades ofliver injury. The number of units of blood transfused, the magnitude of the operative treatment required, the liver-related complications and the liver-related mortality correlated well with the OIS grade. The OIS grade was unable to predict the need for laparotomy or the length of stay in hospital. We conclude that the OIS is a useful, practical and important tool for the categorization of liver injuries, and it may prove to be the universally accepted classification scheme in liver trauma.

    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). Documenting the burden of injury also requires evaluation of the impact of post-trauma impairments, disabilities and handicaps. Trauma epidemiology helps define health service and research priorities, contributes to identify disadvantaged groups, and also facilitates the elaboration of comparable measures for outcome predictions.

    1988-07-01

    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.

On 4th day, post trauma partial pressure of oxygen dropped to 38 mm of mercury (Hg), not improving even on high positive end-expiratory pressure of 18 cm water (H2O), inverse ratio ventilation and fraction of inspired oxygen of 1. Extracorporeal membrane oxygenation was ruled out due to the risk of hemorrhage from trauma sites. Thereafter, hypothermia along with muscle paralysis was considered to reduce total body oxygen consumption. Patient's condition improved under hypothermia, and he was extubated and taken up for fracture fixation surgeries and discharged later in stable condition. PMID:26195862

    Rationale: Acute lung injury is a common complication after severe trauma, which predisposes patients to multiple organ failure. This syndrome largely accounts for the late mortality that arises and despite many theories, the pathological mechanism is not fully understood. Discovery of histone-induced toxicity in mice presents a new dimension for elucidating the underlying pathophysiology. Objectives: To investigate the pathological roles of circulating histones in trauma-induced lung injury. Methods: Circulating histone levels in patients with severe trauma were determined and correlated with respiratory failure and Sequential Organ Failure Assessment (SOFA) scores. Their cause–effect relationship was studied using cells and mouse models. Measurements and Main Results: In a cohort of 52 patients with severe nonthoracic blunt trauma, circulating histones surged immediately after trauma to levels that were toxic to cultured endothelial cells. The high levels were significantly associated with the incidence of acute lung injury and SOFA scores, as well as markers of endothelial damage and coagulation activation. In in vitro systems, histones damaged endothelial cells, stimulated cytokine release, and induced neutrophil extracellular trap formation and myeloperoxidase release. Cellular toxicity resulted from their direct membrane interaction and resultant calcium influx. In mouse models, cytokines and markers for endothelial damage and coagulation activation significantly increased immediately after trauma or histone infusion. Pathological examinations showed that lungs were the predominantly affected organ with edema, hemorrhage, microvascular thrombosis, and neutrophil congestion. An anti-histone antibody could reduce these changes and protect mice from histone-induced lethality. Conclusions: This study elucidates a new mechanism for acute lung injury after severe trauma and proposes that circulating histones are viable therapeutic targets for improving survival

    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

    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

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

  5. Trauma-Focused CBT for Youth who Experience Ongoing Traumas

    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

  7. Assuring optimal trauma care: the role of trauma centre accreditation

    Simons, Richard; Kirkpatrick, Andrew

    2002-01-01

    Optimal care of the injured patient requires the delivery of appropriate, definitive care shortly after injury. Over the last 30 to 40 years, civilian trauma systems and trauma centres have been developed in the United States based on experience gained in military conflicts, particularly in Korea and Vietnam. A similar process is evolving in Canada. National trauma committees in the US and Canada have defined optimal resources to meet the goal of rapid, appropriate care in trauma centres. They have introduced programs (verification or accreditation) to externally audit trauma centre performance based on these guidelines. It is generally accepted that implementing trauma systems results in decreased preventable death and improved survival after trauma. What is less clear is the degree to which each facet of trauma system development contributes to this improvement. The relative importance of national performance guidelines and trauma centre audit as integral steps toward improved outcomes following injury are reviewed. Current Trauma Association of Canada guidelines for trauma centres are presented and the process of trauma centre accreditation is discussed. PMID:12174987

    Multiple system atrophy (MSA) is characterized clinically by parkinsonism, cerebellar, autonomic, and corticospinal features of variable severity. When the presentation is only parkinsonism, the disease might be difficult to differentiate from Parkinson’s disease (PD). We present a case of an 80-year-old man with previous diagnosis of PD. One year after the diagnosis, he had a whiplash cervical trauma due to a tricycle accident caused by a hole in the road. This low-energy trauma caused an unstable C4–C5 cervical fracture with spinal cord injury, which required surgical decompression and stabilization. Neurological examination showed marked postural instability, no rest and postural tremor, finger tapping slowed on the right, spastic tetraparesis (ASIA D) – predominantly on the left side, brisk deep tendon reflexes in the upper and lower extremities, and bilateral extensor plantar response. He also presented with vertical gaze restriction, mild hypometria in horizontal saccades, moderate dysphagia, and dysphonia. As atypical parkinsonism was suspected, he underwent an MRI that revealed conjunction of findings suggestive of parkinsonian-type MSA. In our case, we hypothesize that the loss of postural reflexes, as an early manifestation of MSA, did not allow the patient to have an effective reaction response to a low-energy trauma, resulting in a more severe injury. With this case report, we speculate that the severe spinal lesions caused by minor accidents can be an early sign of postural instability, which may lead to clinical suspicion of neurodegenerative disorder manifested by postural reflexes impairment.

    2011-01-01

    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.

    In the late 1990s, a Department of Defense subcommittee screened more than 100 civilian trauma centers according to the number of admissions, percentage of penetrating trauma, and institutional interest in relation to the specific training missions of each of the three service branches. By the end of 2001, the Army started a program at University of Miami/Ryder Trauma Center, the Navy began a similar program at University of Southern California/Los Angeles County Medical Center, and the Air Force initiated three Centers for the Sustainment of Trauma and Readiness Skills (C-STARS) at busy academic medical centers: R. Adams Cowley Shock Trauma Center at the University of Maryland (C-STARS Baltimore), Saint Louis University (C-STARS St. Louis), and The University Hospital/University of Cincinnati (C-STARS Cincinnati). Each center focuses on three key areas, didactic training, state-of-the-art simulation and expeditionary equipment training, as well as actual clinical experience in the acute management of trauma patients. Each is integral to delivering lifesaving combat casualty care in theater. Initially, there were growing pains and the struggle to develop an effective curriculum in a short period. With the foresight of each trauma training center director and a dynamic exchange of information with civilian trauma leaders and frontline war fighters, there has been a continuous evolution and improvement of each center's curriculum. Now, it is clear that the longest military conflict in US history and the first of the 21st century has led to numerous innovations in cutting edge trauma training on a comprehensive array of topics. This report provides an overview of the decade-long evolutionary process in providing the highest-quality medical care for our injured heroes. PMID:23192074

    2015-08-12

    In elderly patients, a blunt trauma of the chest is associated with a significant risk of complications and mortality. The number of ribs fractures (≥ 4), the presence of bilateral rib fractures, of a pulmonary contusion, of existent comorbidities or acute extra-thoracic traumatic lesions, and lastly the severity of thoracic pain, are indeed important risk factors of complications and mortality. Their presence may require hospitalization of the patient. When complications do occur, they are represented by alveolar hypoventilation, pulmonary atelectasia and broncho-pulmonary infections. When hospitalization is required, it may allow for the specific treatment of thoracic pain, including locoregional anesthesia techniques. PMID:26449103

    Musculoskeletal (MSK) trauma is commonly encountered in the emergency department. Computed tomography and radiography are the main forms of imaging assessment, but the use of magnetic resonance (MR) imaging has become more common in the emergency room (ER) setting for evaluation of low-velocity/sports-related injury and high-velocity injury. The superior soft tissue contrast and detail provided by MR imaging gives clinicians a powerful tool in the management of acute MSK injury in the ER. This article provides an overview of techniques and considerations when using MR imaging in the evaluation of some of the common injuries seen in the ER setting. PMID:27150325

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film. This review discusses the use, advantages and disadvantages of the different imaging techniques used in spinal trauma patients and the criteria used in selecting patients who do not need imaging. Finally an overview of different types of spinal injuries is given

  17. Supporting the early use of echocardiography in blunt chest trauma

    PubMed Central

    2012-01-01

    This case reports a very unusual mechanism of cardiac rupture following an episode of multiple blunt chest trauma. The patient, a professional jockey, was trampled by horses, and although shocked on hospital admission, he did not present with signs and symptoms that were consistent with cardiogenic shock. This case highlights the difficult and subjective nature of clinical examination in emergency situations when dealing with cases of acute cardiac tamponade. It further emphasises the lack of sensitivity of traditional trauma imaging and investigative approaches such as the standard anteroposterior chest X-ray and electrocardiogram. The diagnosis of acute cardiac tamponade was not made until tertiary-care-centre arrival, when ultrasound technology in the form of bedside echocardiography was used, facilitating emergency surgery to repair a ruptured left ventricle. It is hoped that the sharing of this case will alert fellow clinicians to this uncommon but possible mechanism of cardiac rupture and subsequent tamponade, encourage the early use of echocardiography at the bedside in hypotensive blunt chest trauma cases and reinforce the principles of the Advanced Trauma Life Support course in treating trauma victims.

    Non-accidental trauma (NAT) represents a significant cause of morbidity and mortality in the pediatric population. The management of these patients often involves many care providers including the surgeon. Victims of NAT often present with multiple injuries and as such should be treated as trauma patients with complete trauma evaluation including primary, secondary and tertiary surveys. Common injury patterns in NAT include extremity fractures, closed head injury and intra-abdominal injury. Brain imaging is of importance to rule out acute or sub-acute intracranial hemorrhage. Children under the age of 5 years with acute intracranial pathology should also be evaluated by an ophthalmologist to rule out retinal hemorrhages, which are considered pathognomonic for child abuse from violent shaking. In instances when abdominal injury is suspected, prompt evaluation by a surgeon is recommended along with CT imaging. Finding of extremity fractures should prompt evaluation by an orthopedic surgeon. At our institution, all patients with suspected NAT are admitted to the pediatric surgery service for complete evaluation and management. We encourage other pediatric trauma centers to employ a similar approach so that these complicated patients are managed safely and effectively. PMID:25772160

Our focus was on high-grade splenic injuries, defined as AAST injury grade III-V. The first paper was an update of the 2003 Eastern Association for the Surgery of Trauma (EAST) practice management guidelines for nonoperative management of injury to the spleen. The second paper was an American Association for the Surgery of Trauma (AAST) 2012 plenary paper evaluating the predictive role of contrast blush on CT scan in AAST grade IV and V splenic injuries. Our last article was from Europe and investigates the effects of angioembolization of splenic artery on splenic function after high-grade splenic trauma (AAST grade III-V). The EBT-TACS Journal Club elaborated conclusions and recommendations for the management of high-grade splenic trauma. PMID:23912375

    Trauma-related injury in fast developing countries are linked to 90% of international mortality rates, which can be greatly reduced by improvements in often non-existent or non-centralized emergency medical systems (EMS)—particularly in the pre-hospital care phase. Traditional trauma training protocols—such as Advanced Trauma Life Support (ATLS), International Trauma Life Support (ITLS), and Basic Life Support (BLS)—have failed to produce an effective pre-hospital ground force of medical first responders. To overcome these barriers, we propose a new four-tiered set of trauma training protocols: Massive Open Online Course (MOOC) Trauma Training, Acute Trauma Training (ATT), Broad Trauma Training (BTT), and Cardiac and Trauma Training (CTT). These standards are specifically differentiated to accommodate the educational and socioeconomic diversity found in fast developing settings, where each free course is taught in native, lay language while ensuring the education standards are maintained by fully incorporating high-fidelity simulation, video-recorded debriefing, and retraining. The innovative pedagogy of this trauma education program utilizes MOOC for global scalability and a “train-the-trainer” approach for exponential growth—both components help fast developing countries reach a critical mass of first responders needed for the base of an evolving EMS.

    Gluteal compartment syndrome (GCS) is extremely rare when compared to compartment syndrome in other anatomical regions, such as the forearm or the lower leg. It usually occurs in drug users following prolonged immobilization due to loss of consciousness. Another possible cause is trauma, which is rare and has only few reports in the literature. Physical examination may show tense and swollen buttocks and severe pain caused by passive range of motion. We present the case of a 70-year-old man who developed GCS after prolonged anterior-posterior pelvis compression. The physical examination revealed swelling, scrotal hematoma, and left ankle extension weakness. An unstable pelvic ring injury was diagnosed and the patient was taken to surgery. Measurement of the intracompartmental pressure was measured in the operating room, thereby confirming the diagnosis. Emergent fasciotomy was performed to decompress the three affected compartments. Trauma surgeons must be aware of the possibility of gluteal compartment syndrome in patients who have an acute pelvic trauma with buttock swelling and excessive pain of the gluteal region. Any delay in diagnosis or treatment can be devastating, causing permanent disability, irreversible loss of gluteal muscles, sciatic nerve palsy, kidney failure, or even death. PMID:27579205

    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

    Massive transfusion practices were transformed during the 1970s without solid evidence supporting the use of component therapy. A manual literature search was performed for all references to the lethal triad, acute or early coagulopathy of trauma, fresh whole blood, and component transfusion therapy in massive trauma, and damage control resuscitation. Data from recent wars suggest traditional component therapy causes a nonhemostatic resuscitation worsening the propagation of the lethal triad hastening death. These same studies also indicate the advantage of fresh whole blood over component therapy even when administered in a 1:1:1 replacement ratio. PMID:26897426

    2011-01-01

    Regional anesthesia is an established method to provide analgesia for patients in the operating room and during the postoperative phase. While regional anesthesia offers unique advantages, as shown by the recent military experience, it is not commonly utilized in the prehospital or emergency department setting. Most often, regional anesthesia techniques for traumatized patients are first utilized in the operating room for procedural anesthesia or for postoperative pain control. While infiltration or single nerve block procedures are often used by surgeons or emergency medicine physicians in the preoperative phase, more advanced techniques such as plexus block procedures or regional catheter placements are more commonly performed by anesthesiologists for surgery or postoperative pain control. These regional techniques offer advantages over intravenous anesthesia, not just in the perioperative phase but also in the acute phase of traumatized patients and during the initial transport of injured patients. Anesthesiologists have extensive experience with regional techniques and are able to introduce regional anesthesia into settings outside the operating room and in the early treatment phases of trauma patients.

    Tension pneumothorax is one of the leading causes of preventable death in trauma patients. Needle thoracotomy (NT) is the currently accepted first-line intervention but has not been well validated. In this review, we have critically discussed the evidence for NT procedure, re-examined the recommendations by the Advanced Trauma Life Support organization and investigated the safest and most effective way of NT. The current evidence to support the use of NT is limited. However, when used, it should be applied in the 2nd intercostal space at midclavicular line using a catheter length of at least 4.5 cm. Alternative measures should be studied for better prehospital management of tension pneumothorax. PMID:26633663

    The changing complexity of maxillofacial fractures in recent years has created a situation where classical systems of classification of maxillofacial injuries fall short of defining trauma particularly that observed with high-velocity collisions where more than one region of the maxillofacial skeleton is affected. Trauma scoring systems designed specifically for the maxillofacial region are aimed to provide a more accurate assessment of the injury, its prognosis, the possible treatment outcomes, economics, length of hospital stay, and triage. The evolution and logic of such systems along with their merits and demerits are discussed. The author also proposes a new system to aid users in quickly and methodically choosing the system best suited to their needs without having to study a plethora of literature available in order to isolate their choice.

    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.

    In 2009, 3 years after the foundation of the Trauma Network of the German Society for Trauma (TraumaNetzwerkD DGU), the majority of German hospitals participating in the treatment of seriously injured patients is registered in regional trauma networks (TNW). Currently there are 41 trauma networks with more than 660 hospitals in existence, 18 more are registered but are still in the planning phase. Each Federal State has an average of 39 trauma centres of different levels taking part in the treatment of seriously injured patients and every trauma network has an average catchment area of 8708 km(2). The most favourable geographical infrastructure conditions exist in Nordrhein-Westfalen, the least favourable in Sachsen-Anhalt and Mecklenburg-Vorpommern. A total of 95 hospitals have already fulfilled the first audit of the structural, personnel and qualitative requirements by the certification bodies. Examination of the check lists of 26 hospitals showed shortcomings in the clinical structure so that these hospitals must be rechecked after correction of the shortcomings. A total of 59 hospitals throughout Germany were successfully audited and only one failed to fulfil the requirements. Because of the varying sizes of the trauma networks there are differences in the areas covered by each trauma network and trauma centre. Concerning the process of certification and auditing (together with the company DIOcert) it could be seen that by careful examination of the check lists of each hospital unforeseen problems during the audit could be avoided. The following article will present the current state of development of the Trauma Network of the German Society for Trauma and describe the certification and auditing process. PMID:19756455

Study design Children with abusive head trauma (n = 28) and age, sex matched children with non-abusive head trauma (n = 20) admitted to one inpatient pediatric rehabilitation unit from 1995–2012 were studied. Acute hospitalization and inpatient rehabilitation records were retrospectively reviewed for pertinent clinical data: initial GCS score, signs of increased intracranial pressure, neuroimaging findings, and presence of associated injuries. Functional status at admission to and discharge from inpatient rehabilitation was assessed using the Functional Independence Measure for Children (WeeFIM). Outcome at discharge and outpatient follow-up was described based on attainment of independent ambulation and expressive language. Results Children with abusive and non-abusive head trauma had similar levels of injury severity although associated injuries were greater in abusive head trauma. Functional impairment upon admission to inpatient rehabilitation was comparable and functional gains during inpatient rehabilitation were similar between groups. More children with non-abusive than abusive head trauma attained independent ambulation and expressive language after discharge from rehabilitation; the difference was no longer significant when only children greater than 12 months of age at injury were examined. There was variability in delay to obtain these skills and quality of gained skills in both groups. Conclusions Despite more associated injuries, children with abusive head trauma make significant functional gains during inpatient rehabilitation comparable with an age and sex matched sample with non-abusive head trauma. Key functional skills may be gained by children in both groups following discharge from inpatient rehabilitation. PMID:24321537

    The authors report an isolated common femoral artery injury caused by blunt trauma with dissection and secondary ischaemia. A 21-year-old man was admitted to hospital after being stabbed during acute alcoholic intoxication. He presented with a stab wound on the left leg and blunt trauma in the right groin. The surgical exploration of the left-sided wound did not disclose any vascular injury. After a 12-hour period of observation, the patient was discharged. Six hours later, he came back with severe ischaemia on the right leg caused by a femoral artery dissection. The patient underwent surgical revascularization, and fully recovered. Isolated artery blunt trauma is a rare event. In this observation, the absence of early symptoms resulted in delayed diagnosis. PMID:19241930

    The current report reviews a case of mixed dental trauma consequent to a fall by an older patient. The patient’s teeth were forced out of alignment by the trauma and suffered pulpal necrosis. Treatment involved not only healing the acute injuries, but also attending to some subtle delayed problems that became apparent during treatment. Treatments involving endodontics, periodontics, orthodontics, and restorative dentistry were used to address all of the patient’s concerns. This insured that the traumatic occlusion was corrected, appropriate esthetics was restored and normal speech and function was regained. All signs of trauma were recognized, every treatment step was documented, and appropriate follow-up was provided throughout the recovery period. PMID:25419251

    Although the exact benefit of adjunctive splenic artery embolization (SAE) in the nonoperative management (NOM) of patients with blunt splenic trauma has been debated, the role of transcatheter embolization in delayed splenic hemorrhage is rarely addressed. The purpose of this study was to evaluate the effectiveness of SAE in the management of patients who presented at least 3 days after initial splenic trauma with delayed hemorrhage. During a 24-month period 4 patients (all male; ages 19-49 years) presented with acute onset of pain 5-70 days after blunt trauma to the left upper quadrant. Two had known splenic injuries that had been managed nonoperatively. All had computed axial tomography evidence of active splenic hemorrhage or false aneurysm on representation. All underwent successful SAE. Follow-up ranged from 28 to 370 days. These cases and a review of the literature indicate that SAE is safe and effective for NOM failure caused by delayed manifestations of splenic arterial injury.

If the current trend continues, a predicted extra 5 million lives will be lost in this decade. This article aims to create an awareness of the scale of the problem of road trauma and the inequality in the resources available to address this problem. It also describes the responses from the international organisations and the orthopaedic community in dealing with this issue. The International Orthopaedic community has a unique opportunity and moral obligation to play a part in changing this trend of global trauma. PMID:27163075

    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

    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. PMID:27456509

    Severe haemorrhage is a significant cause of death in trauma patients. In the case of massive blood loss a combination of coagulation defects, acidosis and hypothermia arise, which are accompanied by high morbidity and mortality rates unless properly corrected. Research in wounded military showed that a high ratio of fresh frozen plasma to packed red blood cells (FFP:PRBC) seemed to have a positive effect on survival. These studies do not provide a definition of the ideal ratio FFP:PRBC; the ratio in which a positive effect is seen varies from 1:1 to 1:3. Unnecessary FFP transfusions in trauma patients without imminent severe haemorrhage increase the risk of complications such as multi-organ failure and acute respiratory distress syndrome. Additional research is required into the accuracy of diagnosis of acute coagulation disorders. PMID:21291576

    Objective Chronic subdural hematoma (CSDH) is relatively common in neurosurgical field. However not all patients develop CSDH after minor head trauma. In this study, we evaluate the risk factors of post-traumatic CSDH. Methods Two-hundred and seventy-seven patients were enrolled and analyzed in this study from January 2012 to December 2013. Of those, 20 participants had minor head trauma developed CSDH afterward. We also included 257 patients with minor head trauma who did not develop CSDH during the same follow-up period as the control group. We investigated the risk factors related to the development of CSDH after minor head trauma. Results Old age (p=0.014), preexisting diabetes mellitus (p=0.010), hypertension (p=0.026), history of cerebral infarction (p=0.035), antiplatelet agents (p=0.000), acute subdural hematoma in the convexity (p=0.000), encephalomalacia (p=0.029), and long distance between skull and brain parenchyma (p=0.000) were significantly correlated with the development of CSDH after trauma. Multivariate analysis revealed that only the maximum distance between the skull and the cerebral parenchyma was the independent risk factor for the occurrence of CSDH (hazard ratio 2.55, p=0.000). Conclusion We should consider the possibility of developing CSDH in the post-traumatic patients with the identified risk factors. PMID:27169043

    A multi-theoretical couple/family therapy clinical social work practice model synthesizes various social, family, trauma, and psychodynamic theories to inform a biopsychosocial assessment that guides clinical interventions. The client population involves adult partners who have negotiated the impact of childhood trauma, i.e., physical, sexual, and emotional abuses, including culturally sanctioned trauma. Couples may also be dealing with the aftermath of acute trauma related to interpersonal violence, political conflict, and/or the dislocations related to refugee or new immigrant status. Clinical examples demonstrate the usefulness of the model as well as contraindications when active physical violence is present. The construct of resilience remains a central focus in assessment and treatment. Specific attention to cultural and racial diversity enriches both assessment and treatment interventions with these high-risk couples and families. This practice model will be explicated in depth in an upcoming publication from Columbia University Press titled Transforming the Legacies of Trauma in Couple Therapy. PMID:15774396

    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

  8. Prognosis of patients with whiplash-associated disorders consulting physiotherapy: development of a predictive model for recovery

    2012-01-01

    Background Patients with whiplash-associated disorders (WAD) have a generally favourable prognosis, yet some develop longstanding pain and disability. Predicting who will recover from WAD shortly after a traffic collision is very challenging for health care providers such as physical therapists. Therefore, we aimed to develop a prediction model for the recovery of WAD in a cohort of patients who consulted physical therapists within six weeks after the injury. Methods Our cohort included 680 adult patients with WAD who were injured in Saskatchewan, Canada, between 1997 and 1999. All patients had consulted a physical therapist as a result of the injury. Baseline prognostic factors were collected from an injury questionnaire administered by Saskatchewan Government Insurance. The outcome, global self-perceived recovery, was assessed by telephone interviews six weeks, three and six months later. Twenty-five possible baseline prognostic factors were considered in the analyses. A prediction model was built using Cox regression. The predictive ability of the model was estimated with concordance statistics (c-index). Internal validity was checked using bootstrapping. Results Our final prediction model included: age, number of days to reporting the collision, neck pain intensity, low back pain intensity, pain other than neck and back pain, headache before collision and recovery expectations. The model had an acceptable level of predictive ability with a c-index of 0.68 (95% CI: 0.65, 0.71). Internal validation showed that our model was robust and had a good fit. Conclusions We developed a model predicting recovery from WAD, in a cohort of patients who consulted physical therapists. Our model has adequate predictive ability. However, to be fully incorporated in clinical practice the model needs to be validated in other populations and tested in clinical settings. PMID:23273330

    This randomized controlled trial investigated the effectiveness and cost-effectiveness of dry-needling and exercise compared with sham dry-needling and exercise for chronic whiplash-associated disorders (WAD). The setting was a single university centre and 4 physiotherapy practices in Queensland, Australia. Eighty patients with chronic WAD (>3 months) were enrolled between June 2009 and August 2012 with 1-year follow-up completed in August 2013. The interventions were 6 weeks of dry-needling to posterior neck muscles (n = 40) and exercise or sham dry-needling and exercise (n = 40). The primary outcomes of the Neck Disability Index (NDI) and self-rated recovery were measured at baseline, 6 and 12 weeks, 6 and 12 months by a blinded assessor. Analysis was intention to treat. An economic evaluation was planned but missing data deemed further analysis unwarranted. Seventy-nine patients (99%) were followed up at 6 weeks, 78 (98%) at 12 weeks, 74 (93%) at 6 months, and 73 (91%) at 12 months. The dry-needling and exercise intervention was more effective than sham dry-needling and exercise in reducing disability at 6 and 12 months but not at 6 and 12 weeks. The treatment effects were small and not clinically worthwhile. At 6 weeks, the treatment effect on the 0-100 NDI was -0.3 (95% confidence interval -5.4 to 4.7), 12 weeks -0.3 (-5.2 to 4.9), 6 months -4.4 (-9.6 to -0.74), and 12 months -3.8 (-9.1 to -0.5). There was no effect for self-rated recovery. In patients with chronic WAD, dry-needling and exercise has no clinically worthwhile effects over sham dry-needling and exercise. PMID:25790454

    Trauma remains the leading cause of morbidity and mortality in the United States among children aged 1 to 21 years. The most common cause of lethality in pediatric trauma is traumatic brain injury. Early coagulopathy has been commonly observed after severe trauma and is usually associated with severe hemorrhage and/or traumatic brain injury. In contrast to adult patients, massive bleeding is less common after pediatric trauma. The classical drivers of trauma-induced coagulopathy include hypothermia, acidosis, hemodilution, and consumption of coagulation factors secondary to local activation of the coagulation system after severe traumatic injury. Furthermore, there is also recent evidence for a distinct mechanism of trauma-induced coagulopathy that involves the activation of the anticoagulant protein C pathway. Whether this new mechanism of posttraumatic coagulopathy plays a role in children is still unknown. The goal of this review is to summarize the current knowledge on the incidence and potential mechanisms of coagulopathy after pediatric trauma and the role of rapid diagnostic tests for early identification of coagulopathy. Finally, we discuss different options for treating coagulopathy after severe pediatric trauma. PMID:24569507

    To determine the association between expectations to return to work and self-assessed recovery. Positive expectations predict better outcomes in many health conditions, but to date the relationship between expecting to return to work after traffic-related whiplash-associated disorders and actual recovery has not been reported. We assessed early expectations for return to work in a cohort of 2,335 individuals with traffic-related whiplash injury to the neck. Using multivariable Cox proportional hazard analysis we assessed the association between return to work expectations and self-perceived recovery during the first year following the event. After adjusting for the effects of sociodemographic characteristics, initial pain and symptoms, post-crash mood, prior health status and collision-related factors, those who expected to return to work reported global recovery 42% more quickly than those who did not have positive expectations (HRR = 1.42, 95% CI 1.26–1.60). Knowledge of return to work expectation provides an important prognostic tool to clinicians for recovery. PMID:19343376

    Whiplash Associated Disorders (WAD) refers to the multifaceted and chronic burden that is common after a whiplash injury. Tools to assist in the diagnosis of WAD and an increased understanding of neck muscle behaviour are needed. We examined the multilayer dorsal neck muscle behaviour in nine women with chronic WAD versus healthy controls during the entire sequence of a dynamic low-loaded neck extension exercise, which was recorded using real-time ultrasound movies with high frame rates. Principal component analysis and orthogonal partial least squares were used to analyse mechanical muscle strain (deformation in elongation and shortening). The WAD group showed more shortening during the neck extension phase in the trapezius muscle and during both the neck extension and the return to neutral phase in the multifidus muscle. For the first time, a novel non-invasive method is presented that is capable of detecting altered dorsal muscle strain in women with WAD during an entire exercise sequence. This method may be a breakthrough for the future diagnosis and treatment of WAD. PMID:27484361

    2016-08-01

    The fear avoidance model (FAM) has been proposed to explain the development of chronic disability in a variety of conditions including whiplash-associated disorders (WADs). The FAM does not account for symptoms of posttraumatic stress and sensory hypersensitivity, which are associated with poor recovery from whiplash injury. The aim of this study was to explore a model for the maintenance of pain and related disability in people with WAD including symptoms of PTSD, sensory hypersensitivity, and FAM components. The relationship between individual components in the model and disability and how these relationships changed over the first 12 weeks after injury were investigated. We performed a longitudinal study of 103 (74 female) patients with WAD. Measures of pain intensity, cold and mechanical pain thresholds, symptoms of posttraumatic stress, pain catastrophising, kinesiophobia, and fear of cervical spine movement were collected within 6 weeks of injury and at 12 weeks after injury. Mixed-model analysis using Neck Disability Index (NDI) scores and average 24-hour pain intensity as the dependent variables revealed that overall model fit was greatest when measures of fear of movement, posttraumatic stress, and sensory hypersensitivity were included. The interactive effects of time with catastrophising and time with fear of activity of the cervical spine were also included in the best model for disability. These results provide preliminary support for the addition of neurobiological and stress system components to the FAM to explain poor outcome in patients with WAD. PMID:27007066

    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.

    We report a case of acute chylous ascites formation presenting as peritonitis (acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse. The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of "chyle" occurs rapidly, the patient may present with signs of peritonitis. Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation, appendicitis or visceral ischemia. Less than 100 cases of acute chylous peritonitis have been reported. Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days (or even weeks) after the onset of symptoms of pancreatitis. This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis, and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis. The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer, since, due to hypertriglyceridemia, serum amylase values appeared within the normal range. Moreover, abdominal computed tomography imaging was not diagnostic for pancreatitis. Following abdominal lavage and drainage, the patient was successfully treated with total parenteral nutrition and octreotide. PMID:22563182

    Summary Studies examining the association between childhood trauma exposure and neuroendocrine functioning have returned inconsistent findings. To date, few studies have accounted for the role exposure to different types of childhood trauma may have on different neuroendocrine adaptations, and no study has examined this association using multiple indices of hypothalamic—pituitary—adrenal axis (HPA-axis) functioning. The purpose of this study was to characterize the unique associations between exposure to physical abuse, emotional abuse, and non-intentional trauma, and multiple indices of HPA-axis functioning. Methods A community sample of 138 youth (aged 9—16) completed the Socially Evaluated Cold Pressor Task (SE-CPT) while their parents completed the Early Trauma Inventory (ETI). All youth then collected 4 diurnal salivary cortisol samples at home across 2 consecutive weekdays. Results High reported exposure to non-intentional trauma was associated with intact diurnal regulation but elevated cortisol at bedtime, physical abuse was associated with faster reactivity to acute stress, and emotional abuse was associated with delayed recovery of cortisol following acute stress. Taken together, there was a heterogeneous relationship among different indices of HPA-axis functioning and trauma subtype. Discussion Different types of childhood trauma exposure are related to distinct anomalies in HPA-axis functioning. This study underscores the importance of research incorporating multiple indices of HPA-axis functioning to inform our understanding of the underlying neuroendocrine dysregulation that may later lead to stress-related psychopathology.

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

    The last 15 years have seen changing patterns of injury in emergency surgery and trauma patients. The ability to diagnose, treat and manage these patients nonoperatively has led to a decline in interest in trauma surgery as a career. In addition, healthcare systems face multiple challenges, including limited resources, an ageing population and increasing subspecialisation of medical care, while maintaining government-directed standards and managing public expectations. In the West, these challenges have led to the emergence of a new subspecialty, ‘acute care surgery’, with some models of care providing dedicated acute surgical units or separating acute and elective streams with the existing manpower resources. The outcomes for emergency surgery patients and efficiency gains are promising. In Singapore, Khoo Teck Puat Hospital has implemented its first dedicated acute surgical unit. This article outlines the evolution of acute care surgery and its relevance to Asia. PMID:27353030

  3. Vascular trauma historical notes.

    2011-03-01

    This article provides a brief historical review of treatment of vascular trauma. Although methods for ligation came into use in the second century, this knowledge was lost during the Dark Ages and did not come back until the Renaissance. Many advances in vascular surgery occurred during the Balkan Wars, World War I, and World War II, although without antibiotics and blood banking, the philosophy of life over limb still ruled. Documenting and repairing both arteries and veins became more common during the Korean and Vietnam conflicts. Increased documentation has revealed that the current conflicts have resulted in more arterial injuries than in previous wars, likely because of improved body armor, improvised explosive device attacks, tourniquet use, and improved medical evacuation time. This brief review emphasizes the great value of mentorship and the legacy of the management of arterial and venous injuries to be passed on. PMID:21502112

    The bone tissue remodeling due to strong physical/working activity is defined as ergonomic markers or MSM (Muscoloskeletal Stress Markers) (Capasso et al. 1999) and MOS (Markers of Occupational Stress). Among them we can find: enthesopaties, arthropaties, non metrical stress and traumas markers. In the present study, the analysis of these traits has been used to clarify habitual activity patterns of four imperial populations from Suburbium: Castel Malnome, Casal Bertone area Q, Via Padre Semeria e Quarto Cappello del Prete. The very high prevalence of activity-induced stress lesions occurred among the individuals of Castel Malnome and Casal Bertone area Q suggests that these groups were involved in strenuous occupations such as, respectively: the processing and storage of salt and the dyeing of textiles and hides discernible from the archaeological context. For the individuals of Via Padre Semeria and Quarto Cappello del Prete the alterations, instead, could be compatibles with agricultural work. PMID:27348990

    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. PMID:23187617

  8. An ecological view of psychological trauma and trauma recovery.

    PubMed

    Harvey, M R

    1996-01-01

    This paper presents an ecological view of psychological trauma and trauma recovery. Individual differences in posttraumatic response and recovery are the result of complex interactions among person, event, and environmental factors. These interactions define the interrelationship of individual and community and together may foster or impede individual recovery. The ecological model proposes a multidimensional definition of trauma recovery and suggests that the efficacy of trauma-focused interventions depends on the degree to which they enhance the person-community relationship and achieve "ecological fit" within individually varied recovery contexts. In attending to the social, cultural and political context of victimization and acknowledging that survivors of traumatic experiences may recover without benefit of clinical intervention, the model highlights the phenomenon of resiliency, and the relevance of community intervention efforts.

    The proteins fibrin, fibrinogen, fibronectin and complement C5b-9 were investigated in mechanically damaged skeletal muscle. An accumulation of fibrin, fibrinogen and fibronectin could be observed immediately after intra-vital trauma in damaged fibre zones, later an accumulation at the torn edges of the fibres. The accumulation of complement C5b-9 began one hour after trauma. After post mortem trauma no positive reactions could be observed for any of the proteins. The degree of expression of these proteins can therefore be used to differentiate between vital and postmortem muscle damage as well as the estimation of wound age in the early antemortem time period.

    A patient with a whiplash injury suffering from prolonged symptoms, including pain and weakness of the right upper extremity and the symptoms of Barré-Liéou syndrome, was diagnosed and treated with the Bi-Digital O-Ring Test as a supplement to standard medical examinations. Radiological findings showed spondylotic canal stenosis with osteophytes and disc protrusions. The Bi-Digital O-Ring Test indicated a strong abnormal response around the right side of his neck and right shoulder, including the area of the vertebral artery and at acupuncture point GB 21, where positive resonant responses to Cytomegalovirus and Streptococcus faecalis were detected. Antibiotic and anti-viral agents, as well as Ku-Oketsu-Zai, a type of Oriental herbal medicine for overcoming blood stagnation or stasis, were administered according to the drug compatibility test using the Bi-Digital O-ring Test and the following clinical results were obtained. Infection at the site of the vertebral artery and the peri-arterial sympathetic nerve plexus was considered as a cause of the prolongation of the symptoms including Barré-Liéou syndrome, in this case. In addition we especially noted, in this clinical case, that the patient's impaired grasping force dramatically improved from 8 kg to 52 kg in a very short periods of time when the patient held suitable medicine selected with the Bi-Digital O-Ring Test drug compatibility test. We assume that the drug action was transferred electromagnetically, by which the pathological electromagnetic oscillations caused by trauma and following infections were scavenged. This effect might lead to an improvement in the coordination of the neuromuscular system. PMID:9494625

    Modern concepts of patient-centered care emphasize effective communication with patients and families, an essential requirement in acute trauma settings. We hypothesized that using a checklist to guide the initial family conversation would improve the family's perception of the interaction. Institutional Review Board-approved, prospective pre/post study involving families of trauma patients admitted to our Level I trauma center for >24 hours. In the control group, families received information according to existing practices. In the study group, residents gave patient information to a first-degree family member using a checklist that guided the interaction. The checklist included a physician introduction, patient condition, list of known injuries, admission unit or intensive care unit, any consultants involved, plans for additional studies or operations, and opportunity for family to ask questions. An 11-item survey was administered 24 to 48 hours after admission to each group that evaluated the trauma team's communication in the areas of physician introduction, patient condition, ongoing treatment, and family perception of the interaction. Responses were on a Likert scale and analyzed using the Wilcoxon-Mann-Whitney test. There were 130 patients in each group. The study group had significantly (P < 0.05) better responses in 8 of 11 items surveyed: physician spoke to family, physician introduction, understanding of their relative's injuries, admitting unit, consultants involved, urgent surgical procedures required, ongoing diagnostic studies, and understanding of the treatment plan. In conclusion, using a checklist improves the perception of the initial communication between the trauma team and family members of trauma patients, especially their understanding of the treatment plan.

    Acute pancreatitis is probably commoner in children than was previously thought. In children it is most commonly associated with trauma or viral infection. The presentation may be subtler than in adults, requiring a high index of suspicion in the clinician. In three children, two boys aged 4 and 10 and a girl of 15 years, acute pancreatitis was suspected because of the findings at ultrasonography and endoscopic retrograde cholangiopancreatography performed when the disease recurred (the boy aged 4), apathy and immobility without dehydration or other obvious causes (the boy aged 10), and severe abdominal pain in combination with vomiting (the girl). All three patients had severely increased (urinary) amylase levels. Most often, acute pancreatitis in children tends to be a self-limiting disease which responds well to conservative treatment.

    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.

    MSOF is a life-threatening complication of trauma. The body is a dynamic interrelated group of systems that work together efficiently. Changes in one system generally have a widespread impact, and soon the entire system is changed. In children with MSOF, the normal equilibrium that is maintained between organ systems does not exist. Generalized disruption of organ functions occur, and the body attempts to compensate and regain its homeostasis. This activity will often benefit certain organs and harm others. If the disruption continues and compensation fails, organ dysfunction occurs and general chaos reigns. Medical and nursing interventions are directed toward supporting individual organ systems before failure occurs. Attempts to provide this support for one system can cause adverse effects to occur in other systems. Although this is a potential result of medical and nursing interventions, often there is no other choice. It is essential that nurses be aware of the systemic consequences of these interventions and carefully evaluate them. Although overall mortality rates are high, children have a better chance for survival than adults. Expert nursing assessments, interventions, and evaluations are essential to maximize this outcome. More research in the area of MSOF in children is necessary, with specific attention to nursing management and the effect on patient outcome. PMID:1883588

    Between 1988 and 2000 a total of 33 patients with traumatic tracheobronchial lesions were diagnosed and treated. The trauma was penetrating in 7 (stab and gun-shot), blunt in 10 (car accidents, compression and falling from heights) and iatrogenic in 16 of them (postintubational--15, after foreign body extraction--1). The main clinical and radiological features were subcutaneous emphysema, hemoptysis, respiratory insufficiency, pneumomediastinum and pneumothorax. The diagnosis was confirmed in all patients by early fiberoptic bronchoscopy. "Watch and see" tactics with massive antibiotics therapy was followed in 4 (12%) patients. A surgical treatment was carried out in 29 (88%) patients as follows: simple repair--19 (58%), left pneumonectomy--2 (6%), tracheal resection and anastomosis "end to end"--2 (6%), tracheostomy--1 (3%), thoracocenthesis and drainage--3 (9%) and cervical mediastinotomy--2 (6%). The operative mortality was 9%. The cause of death in these 3 patients were associated brain and spinal cord injuries. In the rest of patients the early and long-term postoperative results were considered very good. PMID:12515032

    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

    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.

    Trauma is a significant health problem and a leading cause of death in all age groups. Pain related to trauma is frequently severe, but is often undertreated in the trauma population. Opioids are widely used to treat pain in injured patients but have a broad range of undesirable effects in a multitrauma patient such as neurologic and respiratory impairment and delirium. In contrast, regional analgesia confers excellent site-specific pain relief that is free from major side effects, reduces opioid requirement in trauma patients, and is safe and easy to perform. Specific populations that have shown benefits (including morbidity and mortality advantages) with regional analgesic techniques include those with fractured ribs, femur and hip fractures, and patients undergoing digital replantation. Acute compartment syndrome is a potentially devastating sequela of soft-tissue injury that complicates high-energy injuries such as proximal tibia fractures. The use of regional anesthesia in patients at risk for compartment syndrome is controversial; although the data is sparse, there is no evidence that peripheral nerve blocks delay the diagnosis, and these techniques may in fact facilitate the recognition of pathologic breakthrough pain. The benefits of regional analgesia are likely most influential when it is initiated as early as possible, and the performance of nerve blocks both in the emergency room and in the field has been shown to provide quality pain relief with an excellent safety profile.

    Chest trauma is a major health problem with a high mortality. Myocardial infarction secondary to coronary dissection following blunt chest trauma is a rare entity. We describe the case of an inferior MI following blunt chest trauma. A 61-year-old male without any relevant medical history was transported to a hospital after a low-velocity motorcycle accident. The patient was asymptomatic before the accident. The patient developed severe chest pain and an ECG revealed inferior ST segment elevation. After ruling out aortic dissection with angio-CT, a coronary angiograph depicted a proximal occlusion of the right coronary artery. After thrombectomy, a typical image of coronary artery dissection was observed; the image persisted after several runs of thrombectomy and for that reason a bare metal stent was implanted with a good final angiographic result. Five days after admission the patient was discharged home. Cardiac contusion is not uncommon; however acute myocardial infarction is a rare complication of blunt chest trauma. Thorough evaluation with clinical suspicion can lead to optimal medical care. PMID:24062888

    Introduction Evidence-based recommendations are needed to guide the acute management of the bleeding trauma patient, which when implemented may improve patient outcomes. Methods The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing a guideline for the management of bleeding following severe injury. This document presents an updated version of the guideline published by the group in 2007. Recommendations were formulated using a nominal group process, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) hierarchy of evidence and based on a systematic review of published literature. Results Key changes encompassed in this version of the guideline include new recommendations on coagulation support and monitoring and the appropriate use of local haemostatic measures, tourniquets, calcium and desmopressin in the bleeding trauma patient. The remaining recommendations have been reevaluated and graded based on literature published since the last edition of the guideline. Consideration was also given to changes in clinical practice that have taken place during this time period as a result of both new evidence and changes in the general availability of relevant agents and technologies. Conclusions This guideline provides an evidence-based multidisciplinary approach to the management of critically injured bleeding trauma patients. PMID:20370902

    SUMMARY Trauma-induced coagulopathy (TIC) includes heterogeneous coagulopathic syndromes with different underlying causes, and treatment is challenged by limited diagnostic tests to discriminate between these entities in the acute setting. We provide an overview of progress in understanding the mechanisms of TIC and the context for several of the hypotheses that will be tested in “TACTIC”. Although connected to ongoing clinical trials in trauma, TACTIC itself has no intent to conduct clinical trials. We do anticipate that “early translation” of promising results will occur. Functions anticipated at this early translational level include: 1. Basic science groundwork for future therapeutic candidates; 2. Development of acute coagulopathy scoring systems; 3. Coagulation factor composition-based computational analysis; 4. Characterization of novel analytes including tissue factor, polyP, histones, meizo and α-thrombin-antithrombin complexes, factor XIa, platelet markers of activation and trauma, signatures of protein C activation and fibrinolysis markers; 5. Assessment of visco-elastic tests and new point-of-care methods. PMID:26149052

    A case of a 55-year-old woman with iatrogenic vocal cord trauma and sleep-related symptoms is reported. In particular, this case highlights sleep-disordered breathing as a delayed complication after iatrogenic vocal cord trauma. The patient developed acute stridor from a contralateral vocal cord hematoma following vocal fold injection for right vocal cord paralysis. Acute respiratory symptoms resolved with oxygen, steroids, and nebulized therapy, but nocturnal symptoms persisted and polysomnography revealed sleep-related hypoventilation and mild obstructive sleep apnea. Positive pressure therapy was successfully used to ameliorate her symptoms and treat sleep-disordered breathing until her hematoma resolved. In addition to the typically acute respiratory symptoms that may result from vocal cord dysfunction, sleep-disordered breathing may also present as a significant subacute or chronic problem. Management of the acute respiratory symptoms is relatively well established, but clinicians should be alert for more subtle nocturnal symptoms that may require further study with polysomnography.

    Child maltreatment is a serious public health concern, and its detrimental effects can be compounded by traumatic experiences associated with the child welfare (CW) system. Trauma-informed care (TIC) is a promising strategy for addressing traumatized children's needs, but research on the impact of TIC in CW is limited. This study examines initial findings of the Massachusetts Child Trauma Project, a statewide TIC initiative in the CW system and mental health network. After 1 year of implementation, Trauma-Informed Leadership Teams in CW offices emerged as key structures for TIC systems integration, and mental health providers' participation in evidence-based treatment (EBT) learning collaboratives was linked to improvements in trauma-informed individual and agency practices. After approximately 6 months of EBT treatment, children had fewer posttraumatic symptoms and behavior problems compared to baseline. Barriers to TIC that emerged included scarce resources for trauma-related work in the CW agency and few mental providers providing EBTs to young children. Future research might explore variations in TIC across service system components as well as the potential for differential effects across EBT models disseminated through TIC. PMID:26564909

    Objectives: The aim of this study was to compare the effect on self-rated pain, disability, and self-efficacy of 3 interventions for the management of chronic whiplash-associated disorders: physiotherapist-led neck-specific exercise (NSE), physiotherapist-led NSE with the addition of a behavioral approach, or Prescription of Physical Activity (PPA). Materials and Methods: A total of 216 volunteers with chronic whiplash-associated disorders participated in this randomized, assessor blinded, clinical trial of 3 exercise interventions. Self-rated pain/pain bothersomeness (Visual Analogue Scale), disability (Neck Disability Index), and self-efficacy (Self-Efficacy Scale) were evaluated at baseline and at 3 and 6 months. Results: The proportion of patients reaching substantial reduction in pain bothersomness (at least 50% reduction) was more evident (P<0.01) in the 2 NSE groups (29% to 48%) compared with the PPA group (5%) at 3 months. At 6 months 39% to 44% of the patients in the 2 neck-specific groups and 28% in the PPA group reported substantial pain reduction. Reduction of disability was also larger in the 2 neck-specific exercise groups at both 3 and 6 months (P<0.02). Self-efficacy was only improved in the NSE group without a behavioral approach (P=0.02). However, there were no significant differences in any outcomes between the 2 physiotherapist-led NSE groups. Discussion: NSE resulted in superior outcomes compared with PPA in this study, but the observed benefits of adding a behavioral approach to the implementation of exercise in this study were inconclusive.

    BACKGROUND Infection following severe trauma is a significant cause of morbidity and mortality days to weeks after the initial injury. Apolipoproteins play important roles in host defense and circulating concentrations are altered by the acute inflammatory response. The purpose of this study was to determine if patients who acquire infection following severe trauma have significantly lower apolipoprotein levels than trauma patients who do not become infected. METHODS We conducted a case-control study on a prospectively identified cohort of adult patients admitted to our intensive care unit after severe trauma (Injury Severity Score ≥ 16). We compared plasma apolipoprotein levels between patients who acquired an infection within 30 days after trauma (cases) and those that remained infection free (controls). RESULTS Of 40 patients experiencing severe trauma, we identified 22 cases that developed an infection within 30 days after injury. Cases had significantly lower post-trauma plasma levels of apolipoprotein-B (p=0.02) and apolipoprotein-AII (p=0.02) compared to controls. Consistent with previous studies, cases also received greater volumes of crystalloid infusions (p<0.01) and blood transfusions (p<0.01). Cases also had a more profound inflammatory response as measured by Interleukin-6 levels (p=0.02). CONCLUSIONS Infection after severe trauma is associated with decreased circulating apolipoproteins as compared to uninfected controls. Profoundly decreased plasma apolipoproteins B and AII could potentially contribute to the impaired immunity after severe trauma. Apolipoproteins are potential targets for identifying those patients at risk of infection after trauma and for interventions aimed at preventing nosocomial infections. PMID:23511146

  11. Histologic evidence of repetitive blunt force abdominal trauma in four pediatric fatalities.

    In cases of acute fatal child abuse, certain injuries, including cutaneous blunt force trauma, skull fractures, subdural hematomas, intra-abdominal hemorrhage, and retinal hemorrhages are common and well described in the pediatric and forensic literature. These gross findings at autopsy, when taken into consideration with scene investigation and interviews with caregivers, may indicate both a clear manner and cause of death. In such cases, the discovery of additional pathologic changes attributable to older abusive injuries helps support a conclusion of death due to inflicted trauma. We discuss four cases of fatal child abuse in which acute blunt force abdominal trauma was the cause of death. In each of these cases, careful examination with proper sectioning and microscopy of select abdominal tissues revealed that the acute tissue trauma was superimposed on a background of older, healing injury. This older trauma was characterized by classic histologic elements of tissue repair, including fibroblast proliferation, early scar formation, increased vascularity, and hemosiderin-laden macrophages. Iron and trichrome stains were used to confirm the presence of hemosiderin and fibrosis in all four cases, but the recognition of fibroblast proliferation and a reactive vascular pattern was best seen on routine hematoxylin and eosin stains. The gross and microscopic autopsy findings, along with available investigative information, established the diagnosis of chronic physical abuse. PMID:18808370

    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.

    Among solid organ blunt traumas, the liver and spleen are mostly subject to injury. In addition, the liver is also commonly injured in penetrating traumas because of its size, location, and the ease of injury to the "Glisson Capsule". Several enzymes are known to be elevated following trauma. In our study, we evaluated the correlation between the levels of serum aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, and gamma-glutamyl transpeptidase in 57 patients with blunt trauma to the liver and compared these values to the American Association for the Surgery of Trauma trauma grading system. Additionally, we compared the enzyme level elevations in these patients to the enzyme levels of 29 healthy subjects. As expected, we found significant elevations in enzyme levels of trauma patients compared to the control group. The calculated point estimates were not significantly different between grades 1 and 2 trauma. However, grade 3 trauma group showed a significant increase in enzyme levels. PMID:23793528

    Traumatic events are ubiquitous exposures that interact with life course events to increase risk of acute psychopathology and alter mental health trajectories. While the majority of persons exposed to trauma experience mild to moderate psychological distress followed by a return to pre-trauma health, many persons exposed to trauma experience substantial distress that lasts for several years. Therefore, in an effort to understand why exposure to trauma can provoke such a range of reactions, we apply a life course approach that considers the complex accumulation and interaction of life experiences that range from social to biological factors, which occur over the life span—from gestation to death and across generations. We present this evidence in three categories: genetics and biology, individual exposures, and community experiences, followed by discussing challenges in existing research, and directions for future study.

    Geriatric trauma patients (GTPs) suffering minor injuries have suboptimal outcomes compared with younger populations. Patients 65 years or older account for 10% of all traumas but 28% of all trauma deaths. This trauma center established a third tier trauma alert specifically targeting GTPs at risk for poor outcomes. A Delta Alert is activated when GTPs suffer injuries that fall outside traditional trauma alert guidelines. Early identification and treatment of injuries and expedited referral to specialty groups have improved our GTPs' outcomes including decreased mortality and length of stay and increased percentage of GTPs who are discharged home.

    Although hospitals are faced with the challenges of appropriately informing the public regarding health care and protecting the privacy of patients, a comprehensive policy concerning videotaping of trauma resuscitations can be developed to comply with regulatory bodies. Video recording of trauma team resuscitations can be utilized as an effective quality improvement tool to evaluate trauma team performance, psychomotor skills and techniques, and to identify educational needs related to specific trauma populations. Video recording of Trauma resuscitations is an effective tool for improving trauma team performance by educating clinical staff regarding roles and responsibilities. PMID:16265920

    Trauma-induced critical illness is driven by acute inflammation, and elevated systemic interleukin-6 (IL-6) after trauma is a biomarker of adverse outcomes. We constructed a multicompartment, ordinary differential equation model that represents a virtual trauma patient. Individual-specific variants of this model reproduced both systemic inflammation and outcomes of 33 blunt trauma survivors, from which a cohort of 10,000 virtual trauma patients was generated. Model-predicted length of stay in the intensive care unit, degree of multiple organ dysfunction, and IL-6 area under the curve as a function of injury severity were in concordance with the results from a validation cohort of 147 blunt trauma patients. In a subcohort of 98 trauma patients, those with high-IL-6 single-nucleotide polymorphisms (SNPs) exhibited higher plasma IL-6 levels than those with low IL-6 SNPs, matching model predictions. Although IL-6 could drive mortality in individual virtual patients, simulated outcomes in the overall cohort were independent of the propensity to produce IL-6, a prediction verified in the 98-patient subcohort. In silico randomized clinical trials suggested a small survival benefit of IL-6 inhibition, little benefit of IL-1β inhibition, and worse survival after tumor necrosis factor-α inhibition. This study demonstrates the limitations of extrapolating from reductionist mechanisms to outcomes in individuals and populations and demonstrates the use of mechanistic simulation in complex diseases.

    PubMed

    Bacciagaluppi, Marco

    2011-01-01

    This article starts from the DSM definition of psychic trauma. A central source in this field is the 1992 book by Judith Herman. One line of investigation is the sexual abuse of women and children. In an early phase, both Janet and Freud described dissociation as a reaction to trauma. In 1897, Freud disputed the reality of sexual trauma, a position countered later by Ferenczi. In a later phase, this subject was investigated by the American feminist movement. Studies of physical abuse are then described, followed by mental abuse and neglect. Another line of investigation is combat neurosis. The two lines converged in the definition of PTSD and its incorporation into the DSM in 1980. The views on trauma of John Bowlby and Alice Miller are also discussed. The integration of the relational model in psychoanalysis with the trauma literature is presented. The most recent advances are located in neurobiology. The discussion makes a preliminary investigation of the remote causes of war and sexual violence. PMID:21902510

    Objectives: To report unique cases of Ogilvie's syndrome (acute intestinal pseudo-obstruction) following posterior spinal instrumentation in thoraco lumbar trauma. Materials and Methods: A single centre retrospective study. We reviewed the surgical data of 420 patients who underwent thoracolumbar spinal surgery over a period of four years. Two patients who developed post operative Ogilvie's syndromes were identified. Results: The clinical presentation and blood investigations ruled out any infectious pathology. Computed tomography scans ruled out the mechanical obstruction. All patients improved with conservative management. Conclusion: Ogilvie's syndrome should be considered as a differential diagnosis in patients with postoperative significant abdominal distension who had undergone posterior instrumentation for spinal trauma. Early recognition and appropriate conservative treatment would be necessary to prevent complications such as bowel ischemia and perforation. PMID:26692695

    Hurricane Sandy was one of the most devastating storms to hit the United States in history. The impact of the hurricane included power outages, flooding in the New York City subway system and East River tunnels, disrupted communications, acute shortages of gasoline and food, and a death toll of 113 people. In addition, thousands of residences and businesses in New Jersey and New York were destroyed. This article chronicles the first author's personal and professional experiences as a survivor of the hurricane, more specifically in the dual roles of provider and trauma victim, involving informed self-disclosure with a patient who was also a victim of the hurricane. The general analytic framework of therapy is evaluated in the context of the shared trauma faced by patient and provider alike in the face of the hurricane, leading to important implications for future work on resilience and recovery for both the therapist and patient.

    Minor head injuries in children are common, resulting in brain concussion, and these injuries mostly end up without complications. Usually head trauma results in hemorrhagic stroke. Here we present a case of ischemic stroke following a trivial head trauma. A 10-month-old girl presented with posttraumatic right sided hemiparesis with right sided facial palsy. MRI brain revealed an area of acute infarct in the left capsuloganglionic region. The child was initially managed conservatively, as the hematological parameters were normal, and was started on anticoagulant therapy. An improvement in the clinical condition was achieved in 12 hrs of treatment with gain in power and resolution of weakness in 10 days. The specific cause for hemiparesis in the child is not elicited; possibility of genetic and environmental factors can be attributable. PMID:27313936

    Acute compartment syndrome (ACS) is a well-known pathophysiologic complication of trauma or tissue ischemia. ACS affects the appearance, function, and even the viability of the involved limb, and demands immediate diagnosis and treatment. However, ACS is difficult to diagnose and the only effective treatment is decompressive surgical fasciotomy. The clinical signs and symptoms may easily be attributed to other aspects of the injury, which further complicates the diagnosis. This article highlights the latest information regarding the diagnosis of ACS, how to perform fasciotomies, how to manage fasciotomy wounds, and also reviews complications and outcomes of ACS.

    Twenty patients who had suffered spinal trauma were examined by magnetic resonance tomography. Fifteen patients with first degree trauma in Erdmann's classification showed no abnormality. Magnetic resonance tomography of the cervical spine appears to be a suitable method for investigating patients with whiplash injuries. It is indicated following severe flexion injuries with subluxations and neurological symptoms, since it is the only method that can demonstrate the spinal cord directly and completely and show the extent of cord compression. For patients with thoracic trauma and rapidly developing neurological symptoms, magnetic resonance tomography is ideal for showing post-traumatic syringomyelia. Magnetic resonance tomography following whiplash injuries is recommended if plain films of the cervical spine show any abnormalities, as well as for the investigation of acute or sub-acute neurological abnormalities. The various findings are discussed. PMID:3025951

    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.

    Trauma is the commonest cause of death in children and young adults in the USA and the UK and the incidence of both accidental and non-accidental injury continues to increase. In the Western world more pre-retirement years of life are lost annually from trauma than malignant disease, heart disease, and AIDS combined, and by the beginning of the last decade injury deaths outnumbered deaths from all other causes combined in those under 35 years of age. In South Africa, although infectious diseases continue to exact their toll, a similar pattern is emerging. Alcohol and speed are responsible for the majority of motor vehicle accidents, while the increasing ownership of firearms directly parallels the homicide rates from these weapons. Stricter application of the legislation governing alcohol, driving and firearm control is required and a regionalised trauma care programme is desperately needed to contain this epidemic.

    Injured patients stress the transfusion service with frequent demands for uncrossmatched red cells and plasma, occasional requirements for large amounts of blood products and the need for new and better blood products. Transfusion services stress trauma centers with demands for strict accountability for individual blood component units and adherence to indications in a clinical field where research has been difficult, and guidance opinion-based. New data suggest that the most severely injured patients arrive at the trauma center already coagulopathic and that these patients benefit from prompt, specific, corrective treatment. This research is clarifying trauma system requirements for new blood products and blood-product usage patterns, but the inability to obtain informed consent from severely injured patients remains an obstacle to further research.

    Vascular injury in orthopedic trauma is challenging. The risk to life and limb can be high, and clinical signs initially can be subtle. Recognition and management should be a critical skill for every orthopedic surgeon. There are 5 types of vascular injury: intimal injury (flaps, disruptions, or subintimal/intramural hematomas), complete wall defects with pseudoaneurysms or hemorrhage, complete transections with hemorrhage or occlusion, arteriovenous fistulas, and spasm. Intimal defects and subintimal hematomas with possible secondary occlusion are most commonly associated with blunt trauma, whereas wall defects, complete transections, and arteriovenous fistulas usually occur with penetrating trauma. Spasm can occur after either blunt or penetrating trauma to an extremity and is more common in young patients. Clinical presentation of vascular injury may not be straightforward. Physical examination can be misleading or initially unimpressive; a normal pulse examination may be present in 5% to 15% of patients with vascular injury. Detection and treatment of vascular injuries should take place within the context of the overall resuscitation of the patient according to the established principles of the Advanced Trauma Life Support (ATLS) protocols. Advances in the field, made mostly during times of war, have made limb salvage the rule rather than the exception. Teamwork, familiarity with the often subtle signs of vascular injuries, a high index of suspicion, effective communication, appropriate use of imaging modalities, sound knowledge of relevant technique, and sequence of surgical repairs are among the essential factors that will lead to a successful outcome. This article provides a comprehensive literature review on a subject that generates significant controversy and confusion among clinicians involved in the care of trauma patients.

    Injuries to the pancreas and gastrointestinal tract following blunt abdominal trauma continue to be a significant cause of morbidity and mortality in the pediatric age group. Optimal treatment of these injuries is frequently hampered by considerable delays in diagnosis. Factors contributing to these delays include the location of much of the duodenum and the pancreas in the retroperitoneum resulting in an absence of initial symptoms and signs, the often trivial nature of some of the responsible blunt traumatic accidents, inappropriate child-parent or child-physician communication, failure to achieve a meaningful physical examination in uncooperative or unconscious patients, and false negative paracentesis. Eighty per cent of these injuries occurred in boys. Eleven of 16 patients with pancreatic trauma had pseudocysts. A persistently elevated serum amylase level was invariably noted and epigastric mass was palpable in eight patients. Significant delays in diagnosis were prevalent and pseudocysts was misdiagnosed as appendicitis in three cases. Internal drainage by cystgastrostomy or cystjejunostomy was effective operative treatment. In instances of acute pancreatic injuries, sump drains, gastrostomy, cholecystostomy, and total parenteral hyperalimentation were useful therapeutic adjuncts. There was one death for a 6.2 per cent mortality rate. Forty patients had gastrointestinal injuries involving the duodenum in 17, jejunum in 14, ileum in seven, and stomach in two. Perforations occured in 65 per cent of cases, obstructing hematomas in 30 per cent, and mesenteric avulsions in 5 per cent. Associated injuries were observed in 15 patients (37.5 per cent). Pain and tenderness were the only consistent findings. Upper gastrointestinal contrast studies were diagnostic of duodenal hematomas. Eighty per cent of perforations were managed by simple closures and 20 per cent by resection and anastomosis. Obstructing hematomas unassociated with other injuries may be expected to

    The increasing understanding of trauma-induced coagulopathy has led to an expansion of treatment strategies in the acute management of trauma patients. The aim of this manuscript is to give a summary of current recommendations for the treatment of trauma-induced coagulopathy based on current literature and valid guidelines. Thetrauma-induced coagulopathyis an independentacutemultifactorial diseasewith significantimpact on the mortalityof severelyinjured patients. Largely responsible for the occurrence and severity of trauma-induced coagulopathy seems to be tissue trauma and shock-induced hypoperfusion. Coagulopathy is amplified by accompanying factors such as hypothermia or dilution. Diagnosis and therapy of deranged coagulation should start as soon as possible. Routinely tested coagulation parameters are of limited use to confirm diagnosis. Therapy follows the concept of "damage control resuscitation". Infusion of large volumes should be avoided and a mean arterial pressure of 65mmHg (in consideration of contraindications!) may be aimed.A specific protocol for massive transfusion should be introduced and continued.Acidaemia should be prevented and treated by appropriate shock therapy.Loss of body temperature should be prevented and treated. Hypocalcaemia <0.9 mmol/l should be avoided and may be treated. For actively bleeding patients, packed red blood cells (pRBC) may be given at haemoglobin<10g/dl(0,62mmol/l). If massive transfusion is performed using fresh frozen plasma (FFP), a ratio of FFP to pRBC of 1:2 to 1:1 should be achieved.For treatment of hyperfibrinolysis after severe trauma the use of tranexamic acid should be considered at an early stage. Fibrinogen should be substituted at levels <1,5g/l (4,41μmol/l). Prothrombin complex concentrates may be helpfull for treatment of diffuse bleeding or anticoagulativemedikation. In acute bleeding, platelets may be transfused at a platet count <100000/μl. For diffuse bleeding or thrombocytopathic patients

    The resuscitative thoracotomy (RT) is an important procedure in the management of penetrating trauma. As it is performed only in patients with peri-arrest physiology or overt cardiac arrest, survival is low. Experience is also quite variable depending on volume of penetrating trauma in a particular region. Survival ranges from 0% to as high as 89% depending on patient selection, available resources, and location of RT (operating or emergency rooms). In this article, published guidelines are reviewed as well as outcomes. Technical considerations of RT and well as proper training, personnel, and location are also discussed. PMID:25342073

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

    Lesions produced by exposure to noise are frequent in everyday life. Injuries may be found in all systems of the human body, from the digestive to the endocrine, from the cardiovascular to the nervous system. Many organs may be damaged, the ear being one of them. It is known that noise produced by factories, airports, musical instruments and even toys can cause auditory loss. Noises in nature can also cause acoustic trauma. This report is the case history of acoustic trauma caused by lightning. The patient was studied with CAT scan, electroencephalogram, and brain mapping, impedance audiometry with tympanogram and acoustic reflex, audiometry and evoked otoacoustics emissions: distortion products and transients.

    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.

    Orthopedic trauma results in systemic physiologic changes that predispose patients to venous thromboembolism (VTE). In the absence of prophylaxis, VTE incidence may be as high as 60%. Mechanical and pharmacologic thromboprophylaxis are effective in decreasing rates of VTE. Combined mechanical and pharmacologic thromboprophylaxis is more efficacious for decreasing VTE incidence than either regimen independently. If pharmacologic thromboprophylaxis is contraindicated, mechanical prophylaxis should be used. Patients with isolated lower extremity fractures who are ambulatory, or those with isolated upper extremity trauma, do not require pharmacologic prophylaxis in the absence of other VTE risk factors.

    Management of severely injured patients is complex and requires organised, expert care. Regionalised trauma systems are relatively new in the UK and aim to deliver optimal, timely care to injured patients at the most appropriate location. This article discusses the drivers, organisation, processes and outcomes of regionalised trauma care. It also describes the challenges and benefits of working within a trauma system to enable emergency practitioners to reflect on their roles in contemporary trauma care. PMID:26451941

    Acute aortic syndrome is the common denominator for acute events to the aortic wall and encompasses dissection of the aorta, intramural hematoma, formation of aortic ulcers and trauma to the aorta with an annual incidence of up to 35 cases/100.000 between 65 and 75 years of age. Both, inflammation and/or microtrauma at the level of the aortic media layer, and a genetic disposition are promoting elements of AAS, while the extent and anatomic involvement of the ascending aorta call for either surgical resection/repair in the proximal part of the aorta, or an endovascular solution for pathologies in the distal aorta; in all cases of dissection (regardless of location) reconstruction/realignment has been proven to portend better long-term outcomes (in addition to medical management of blood pressure).

    Hemorrhage remains one of the leading causes of trauma-related deaths. Uncontrolled diffuse microvascular bleeding in the course of initial care is common, potentially resulting in exsanguination. Early and aggressive hemostatic intervention increases survival and reduces the incidence of massive transfusion. Thus, timely diagnosis of the underlying coagulation disorders is mandatory. It has been shown that standard coagulation tests do not sufficiently characterize trauma-induced coagulopathy (TIC). This has led to increasing interest in alternatives, such as the viscoelastic test, to diagnose TIC and to provide the basis for a goal-directed hemostatic therapy. The concept of damage control resuscitation (DCR) has been introduced widely in trauma patients with severe bleeding. This strategy addresses important confounders of the coagulation process such as hemodilution, hypothermia, and acidosis; DCR is based on a damage control surgical approach, permissive hypotension, and improvement of hemostatic competence. Many studies have shown benefit in mortality when using high ratios of fresh frozen plasma (FFP) to red blood cells (RBC) as early treatment. However, there is increased awareness that coagulation factor concentrate could be beneficial in the treatment of trauma-induced coagulopathy. PMID:23910535

    The management of massively transfused trauma patients has improved with a better understanding of trauma-induced coagulopathy, the limitations of crystalloid infusion, and the implementation of massive transfusion protocols (MTPs), which encompass transfusion management and other patient care needs to mitigate the "lethal triad" of acidosis, hypothermia, and coagulopathy. MTPs are currently changing in the United States and worldwide because of recent data showing that earlier and more aggressive transfusion intervention and resuscitation with blood components that approximate whole blood significantly decrease mortality. In this context, MTPs are a key element of "damage control resuscitation," which is defined as the systematic approach to major trauma that addresses the lethal triad mentioned above. MTPs using adequate volumes of plasma, and thus coagulation factors, improve patient outcome. The ideal amounts of plasma, platelet, cryoprecipitate and other coagulation factors given in MTPs in relationship to the red blood cell transfusion volume are not known precisely, but until prospective, randomized, clinical trials are performed and more clinical data are obtained, current data support a target ratio of plasma:red blood cell:platelet transfusions of 1:1:1. Future prospective clinical trials will allow continued improvement in MTPs and thus in the overall management of patients with trauma. PMID:19448199

    Pyogenic granuloma (PG) is a reactive local benign vascular lesion, where connective tissue fibrovascular proliferation occurs. The most common etiology of PG is chronic, low-level irritation. PG affects females mainly. The purpose of this paper is to report a giant pyogenic granuloma caused by an acute trauma in the upper lip of an 11-year-old boy. The initial clinical diagnosis suggested PG, which was confirmed after an excisional biopsy and a microscopic exam. Oral lesions of large proportions in children can cause functional, esthetic, and behavioral issues, and should be promptly investigated. PMID:26731254

    The purpose of this review is to investigate the utility of autotransfusion in trauma patients in the past 3 years. A retrospective review was conducted of the charts for whom the Haemonetics Cell Saver autotransfusion device (Haemonetics Corp., Natick, MA) was utilized between January 1, 1993, and December 31, 1995. The estimated blood loss and quantity of blood transfused were noted for abdominal trauma patients. Costs of autotransfusion were then compared to estimated blood bank costs for this group. The Haemonetics Cell Saver autotransfusion device was requested for 592 cases from January 1, 1993, to December 31, 1995. Nonorthopedic trauma cases comprised 25 per cent of all autotransfusion cases. One hundred twenty-six patients had isolated abdominal trauma and had a mean estimated blood loss of 4864 +/- 6070 cc. The average volume of intraoperatively salvaged autologous blood transfused (autotransfusion) per patient was 1547 +/- 2359 cc, or a bank blood equivalent of 6.9 units of packed red blood cells. The total cost of autotransfusion in these patients was $63,252.00. Had bank blood been used instead of salvaged autologous blood, the cost would have been $114,523.00; thus, autotransfusion resulted in a savings of $51,271.00. The use of salvaged autologous blood comprised 45 per cent of total blood transfused. On a case-by-case basis, 75 per cent of cases were cost-effective compared to blood bank costs for an equivalent transfusion. Transfusion of intraoperatively salvaged autologous blood (autotransfusion) is a cost-effective, efficient way to provide blood products to operative trauma patients. PMID:8985070

    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. PMID:27496599

    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. PMID:26460794

    Significance: Traumatic injuries are the leading cause of morbidity and mortality in children. The purpose of this review is to provide an overview of the initial assessment and management of traumatic and burn wounds in children. Special attention is given to wound cleansing, debridement techniques, and considerations for pain management and psychosocial support for children and families. Recent Advances: Basic and translational research over the last 5–7 years has advanced our knowledge related to the optimal care of acute pediatric traumatic and burn wounds. Data concerning methods, volume, solution and timing for irrigation of acute traumatic wounds, timing and methods of wound debridement, including hydrosurgery and plasma knife coblation, and wound dressings are presented. Additionally, data concerning the long-term psychosocial outcomes following acute injury are presented. Critical Issues: The care of pediatric trauma and burn-related wounds requires prompt assessment, pain control, cleansing, debridement, application of appropriate dressings, and close follow-up. Ideally, a knowledgeable multidisciplinary team cares for these patients. A limitation in the care of these patients is the relative paucity of data specific to the care of acute traumatic wounds in the pediatric population. Future Directions: Research is ongoing in the arenas of new debridement techniques and instruments, and in wound dressing technology. Dedicated research on these topics in the pediatric population will serve to strengthen and advance the care of pediatric patients with acute traumatic and burn wounds. PMID:26487978

    During the past 20 years, the development of brain imaging techniques and new biochemical approaches has led to increased understanding of the biological effects of psychological trauma. New hypotheses have been generated about brain development and the roots of antisocial behavior. We now understand that psychological trauma disrupts homeostasis and can cause both short and long-term effects on many organs and systems of the body. Our expanding knowledge of the effects of trauma on the body has inspired new approaches to treating trauma survivors. Biologically informed therapy addresses the physiological effects of trauma, as well as cognitive distortions and maladaptive behaviors. The authors suggest that the most effective therapeutic innovation during the past 20 years for treating trauma survivors has been Eye Movement Desensitization and Reprocessing (EMDR), a therapeutic approach that focuses on resolving trauma using a combination of top-down (cognitive) and bottom-up (affect/body) processing.

    In polytrauma patients a thoracic trauma is one of the most critical injuries and an important trigger of post-traumatic inflammation. About 50% of patients with thoracic trauma are additionally affected by bone fractures. The risk for fracture malunion is considerably increased in such patients, the pathomechanisms being poorly understood. Thoracic trauma causes regional alveolar hypoxia and, subsequently, hypoxemia, which in turn triggers local and systemic inflammation. Therefore, we aimed to unravel the role of oxygen in impaired bone regeneration after thoracic trauma. We hypothesized that short-term breathing of 100% oxygen in the early post-traumatic phase ameliorates inflammation and improves bone regeneration. Mice underwent a femur osteotomy alone or combined with blunt chest trauma 100% oxygen was administered immediately after trauma for two separate 3 hour intervals. Arterial blood gas tensions, microcirculatory perfusion and oxygenation were assessed at 3, 9 and 24 hours after injury. Inflammatory cytokines and markers of oxidative/nitrosative stress were measured in plasma, lung and fracture hematoma. Bone healing was assessed on day 7, 14 and 21. Thoracic trauma induced pulmonary and systemic inflammation and impaired bone healing. Short-term exposure to 100% oxygen in the acute post-traumatic phase significantly attenuated systemic and local inflammatory responses and improved fracture healing without provoking toxic side effects, suggesting that hyperoxia could induce anti-inflammatory and pro-regenerative effects after severe injury. These results suggest that breathing of 100% oxygen in the acute post-traumatic phase might reduce the risk of poorly healing fractures in severely injured patients. PMID:26147725

    Purpose Ocular blast injuries in the military setting are particularly associated with significant maxillofacial trauma and/or brain injury. The opportunity to perform a comprehensive ophthalmic evaluation is frequently limited in the acute multiple trauma scenario. We aim to describe the relationship between the clinical effects of acute ocular and orbital blast trauma with the findings on computerised tomography (CT). Methods This was a retrospective consecutive case series of all soldiers with facial and/or suspected ocular injuries. A total of 80 eyes that had suffered blast injuries of varying severity were studied. Assessment of orbital and ocular CT images were performed by military consultant radiologists. A comparison was made with actual clinical findings. Statistical analysis was performed using Fisher's exact test. Results No pathological findings were described in 37 of the 80 eyes imaged by orbital and ocular CT scans. Clinically, these eyes and orbits were all found to be intact, or had minor trauma. All foreign bodies and penetrating eye injuries were successfully diagnosed by CT. Absence of an orbital fracture did not rule out a globe injury. However, a corneal or scleral defect was less likely when an orbital fracture was absent. Conclusion The eye is a delicate structure prone to injury that requires urgent repair if breached. It is difficult to assess thoroughly in the unconscious or distressed patient. In this context, CT imaging is invaluable to be able to make a relatively confident prediction of clinical findings and decide upon the necessity for acute ophthalmic surgical intervention.

    Previous research has demonstrated that nonclinical factors are associated with differences in clinical care, with uninsured patients receiving decreased resource use. Studies on trauma populations have also shown unclear relationships between insurance status and hospital length of stay (LOS), a commonly used metric for evaluating quality of care. The objective of this study is to define the relationship between insurance status and LOS after trauma using the largest available national trauma dataset and controlling for significant confounders. Data from 2007 to 2010 National Trauma Data Bank were used to compare differences in LOS among three insurance groups: privately insured, publically insured, and uninsured trauma patients. Multivariable regression models adjusted for potential confounding due to baseline differences in injury severity and demographic and clinical factors. A total of 884,493 patients met the inclusion criteria. After adjusting for the influence of covariates, uninsured patients had significantly shorter hospital stays (0.3 days) relative to privately insured patients. Publicly insured patients had longer risk-adjusted LOS (0.9 days). Stratified differences in discharge disposition and injury severity significantly altered the relationship between insurance status and LOS. In conclusion, this study elucidates the association between insurance status and hospital LOS, demonstrating that a patient's ability to pay could alter LOS in acute trauma patients. Additional research is needed to examine causes and outcomes from these differences to increase efficiency in the health care system, decrease costs, and shrink disparities in health outcomes.

    Improvements in the control of haemorrhage after trauma have resulted in survival of many people who would otherwise have died from the initial loss of blood. However, the danger is not over once bleeding has been arrested and blood pressure restored. Two-thirds of patients who die following major trauma now do so as a result of causes other than exsanguination. Trauma evokes a systemic reaction that include an acute, non-specific, immune response associated, paradoxically, with reduced resistance to infection. The result is damage to multiple organs caused by the initial cascade of inflammation aggravated by subsequent sepsis to which the body has become susceptible. This Series examines the biological mechanisms and clinical implications of the cascade of events caused by large-scale trauma that leads to multiorgan failure and death, despite the stemming of blood loss. Furthermore, the stark and robust epidemiological finding – namely, that age has a profound influence on the chances of surviving trauma irrespective of the nature and severity of the injury – will be explored. Advances in our understanding of the inflammatory response to trauma, the impact of ageing on this response, and how this information has led to new and emerging treatments aimed at combating immune dysregulation and reduced immunity after injury will also be discussed.

    Orthopedic trauma is an unforeseen life-changing event. Serious injuries include multiple fractures and amputation. Physical rehabilitation has traditionally focused on addressing functional deficits after traumatic injury, but important psychological factors also can dramatically affect acute and long-term recovery. This review presents the effects of orthopedic trauma on psychological distress, potential interventions for distress reduction after trauma, and implications for participation in rehabilitation. Survivors commonly experience post-traumatic stress syndrome, depression, and anxiety, all of which interfere with functional gains and quality of life. More than 50% of survivors have psychological distress that can last decades after the physical injury has been treated. Early identification of patients with distress can help care teams provide the resources and support to offset the distress. Several options that help trauma patients navigate their short-term recovery include holistic approaches, pastoral care, coping skills, mindfulness, peer visitation, and educational resources. The long-term physical and mental health of the trauma survivor can be enhanced by strategies that connect the survivor to a network of people with similar experiences or injuries, facilitate support groups, and social support networking (The Trauma Survivors Network). Rehabilitation specialists can help optimize patient outcomes and quality of life by participating in and advocating these strategies. PMID:25772720

    The aim of this study was to review the literature regarding the rupture of hydatid cysts into the abdominal cavity after trauma. We present both a new case of hydatid cyst rupture that occurred after blunt abdominal trauma and a literature review of studies published in the English language about hydatid cyst rupture after trauma; studies were accessed from PubMed, Google Scholar, EBSCO, EMBASE, and MEDLINE databases. We identified 22 articles published between 2000 and 2011 about hydatid cyst rupture after trauma. Of these, 5 articles were excluded because of insufficient data, duplication, or absence of intra-abdominal dissemination. The other 17 studies included 68 patients (38 males and 30 females) aged 8 to 76 years who had a ruptured hydatid cyst detected after trauma. The most common trauma included traffic accidents and falls. Despite optimal surgical and antihelmintic therapy, 7 patients developed recurrence. Complications included biliary fistula in 5 patients, incisional hernia in 2 patients, and gastrocutaneous fistula in 1 patient. Death occurred from intraoperative anaphylactic shock in 1 patient and gastrointestinal bleeding and pulmonary failure in 1 patient. Rupture of a hydatid cyst into the peritoneal cavity is rare and challenging for the surgeon. This condition is included in the differential diagnosis of the acute abdomen in endemic areas, especially in young patients. PMID:23113853

    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.

    Exposure to loud sounds damages the auditory periphery and induces maladaptive changes in central parts of the auditory system. Diminished peripheral afferentation and altered inhibition influence the processing of sounds in the auditory cortex. It is unclear, however, which types of inhibitory interneurons are affected by acoustic trauma. Here we used single-unit electrophysiological recording and two-photon calcium imaging in anesthetized mice to evaluate the effects of acute acoustic trauma (125 dB SPL, white noise, 5 min) on the response properties of neurons in the core auditory cortex. Electrophysiological measurements suggested the selective impact of acoustic trauma on inhibitory interneurons in the auditory cortex. To further investigate which interneuronal types were affected, we used two-photon calcium imaging to record the activity of neurons in cortical layers 2/3 and 4, specifically focusing on parvalbumin-positive (PV+) and somatostatin-positive (SST+) interneurons. Spontaneous and pure-tone-evoked firing rates of SST+ interneurons increased in layer 4 immediately after acoustic trauma and remained almost unchanged in layer 2/3. Furthermore, PV+ interneurons with high best frequencies increased their evoked-to-spontaneous firing rate ratios only in layer 2/3 and did not change in layer 4. Finally, acoustic trauma unmasked low-frequency excitatory inputs only in layer 2/3. Our results demonstrate layer-specific changes in the activity of auditory cortical inhibitory interneurons within minutes after acoustic trauma. PMID:26823513

    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.

    Frequently, episodes of care such as preventive clinic visits, acute care, medical procedures, and hospitalization can be emotionally threatening and psychologically traumatizing for pediatric patients. Children are often subject to psychological trauma, demonstrated by anxiety, aggression, anger, and similar expressions of emotion, because they lack control of their environment. This sense of helplessness, coupled with fear and pain can cause children to feel powerless in healthcare settings. These emotional responses can delay important medical treatment, take more time to complete and can reduce patient satisfaction. Healthcare professionals are uniquely positioned to prevent healthcare-induced trauma and reduce healthcare-induced anxiety. This article introduces a new way to choice, agenda, resilience and emotion (CARE) for pediatric patients in the healthcare setting by implementing the four following treatment principles called the care process: (1) Choices: Offer power in a powerless environment; (2) Agenda: Let patients and families know what to expect and what is expected of them; (3) Resilience: Highlight strengths and reframe negatives; and (4) Emotional support: Recognize and normalize common fears and responses. Engaging the CARE principles helps patients and families feel empowered and mitigates, reduces, and may even ameliorate risk of anxiety and trauma responses. PMID:27170924

    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.

  12. 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

    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

    Fibrin glue (FG) is an effective hemostatic agent applied topically to the spleen. In this study, FG was found to be an effective hemostatic agent when applied topically in standardized wounds of the canine liver, spleen, and pancreas. It was markedly more effective, however, when injected intraparenchymally. In a case of severe blunt trauma in a patient with acute alcoholic hepatitis, intraparenchymal FG was lifesaving. Fibrin glue is a useful adjunct in the management of trauma to all the abdominal solid viscera. Intraparenchymal injection is the preferred mode of FG application. PMID:2465750

    Background Injured trauma victims are at risk of developing Posttraumatic Stress Disorder (PTSD) and other post-trauma psychopathology. So far, interventions using cognitive behavioral techniques (CBT) have proven most efficacious in treating early PTSD in highly symptomatic individuals. No early intervention for the prevention of PTSD for all victims has yet proven effective. In the acute psychosocial care for trauma victims, there is a clear need for easily applicable, accessible, cost-efficient early interventions. Objective To describe the design of a randomized controlled trial (RCT) evaluating the effectiveness of a brief Internet-based early intervention that incorporates CBT techniques with the aim of reducing acute psychological distress and preventing long-term PTSD symptoms in injured trauma victims. Method In a two armed RCT, 300 injured trauma victims from two Level-1 trauma centers in Amsterdam, the Netherlands, will be assigned to an intervention or a control group. Inclusion criteria are: being 18 years of age or older, having experienced a traumatic event according to the diagnostic criteria of the DSM-IV and understanding the Dutch language. The intervention group will be given access to the intervention's website (www.traumatips.nl), and are specifically requested to login within the first month postinjury. The primary clinical study outcome is PTSD symptom severity. Secondary outcomes include symptoms of depression and anxiety, quality of life, and social support. In addition, a cost-effectiveness analysis of the intervention will be performed. Data are collected at one week post-injury, prior to first login (baseline), and at 1, 3, 6 and 12 months. Analyses will be on an intention-to-treat basis. Discussion The results will provide more insight into the effects of preventive interventions in general, and Internet-based early interventions specifically, on acute stress reactions and PTSD, in an injured population, during the acute phase after

    The relationship among traumatic injury, the associated metabolic/physiologic responses, and mortality is well established. Tissue hypoperfusion and metabolic derangement may not universally correlate with initial clinical presentation. We hypothesized that anion gap (AG) could be a useful gauge of trauma-related physiologic response and mortality in older patients with relatively lower injury acuity. We retrospectively analyzed data from 711 trauma patients older than 45 years. Parameters examined included demographics, injury characteristics, laboratories, morbidity, and mortality. Univariate and survival analyses were performed using PASW 18. A stepwise correlation exists between increasing Injury Severity Score and AG. Although AG less than 8 to 15 was not associated with a significant increase in mortality, greater mortality was seen for AG greater than 16 with further stepwise increases for AGs greater than 22. Anion gap correlated moderately with serum lactate and poorly with base excess. Increasing AG also correlated with morbidity and greater incidence of intensive care admissions. The presence of any complication increased from 28.6 per cent for patients with AG 12 or less to 45.5 per cent for patients with AG 22 or greater (P < 0.04). These findings support the contention that "low acuity" trauma patients with high AGs may not appear acutely ill but may harbor significant underlying metabolic and physiologic disturbances that could contribute to morbidity and mortality. Higher AG values (i.e., greater than 16) may be associated with worse clinical outcomes. PMID:24165258

    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. Images Figure 1 Figure 2 Figure 3 PMID:1460683

    Computer-assisted orthopaedic surgery (CAOS) is performed by digitizing the patient's anatomy, combining the images in a computerized system, and integrating the surgical instruments into the digitized image background. This allows the surgeon to navigate the surgical instruments and the bone in an improved, virtual visual environment. CAOS in traumatology is performed with images obtained by fluoroscopy, CT, or three-dimensional fluoroscopy. CAOS is used in basic trauma procedures for preoperative planning, fracture reduction, intramedullary nailing, percutaneous screw or plate fixation, and hardware or shrapnel removal. Potential benefits of CAOS include minimal invasiveness, increased accuracy, and decreased radiation exposure. Limitations include a significant learning curve, increased surgical time, requirements for special setup and equipment handling in the operating room, specialized technical support, and cost. Current evidence shows no advantage with CAOS in trauma cases compared with conventional methods. Prospective randomized trials and clinical outcomes are lacking. PMID:20435875

    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.

    OBJECTIVE: The authors review the physiologic basis, indications, techniques, and results of the planned reoperation approach to severe trauma. SUMMARY BACKGROUND DATA: Multivisceral trauma and exsanguinating hemorrhage lead to hypothermia, coagulopathy, and acidosis. Formal resections and reconstructions in these unstable patients often result in irreversible physiologic insult. A new surgical strategy addresses these physiologic concerns by staged control and repair of the injuries. METHOD: The authors review the literature. RESULTS: Indications for planned reoperation include avoidance of irreversible physiologic insult and inability to obtain direct hemostasis or formal abdominal closure. The three phases of the strategy include initial control, stabilization, and delayed reconstruction. Various techniques are used to obtain rapid temporary control of bleeding and hollow visceral spillage. Hypothermia, coagulopathy, and the abdominal compartment syndrome are major postoperative concerns. Definitive repair of the injuries is undertaken after stabilization. CONCLUSION: Planned reoperation offers a simple and effective alternative to the traditional surgical management of complex or multiple injuries in critically wounded patients. PMID:7618965

    Fifty patients with abdominal trauma and possible splenic injury were evaluated by computed tomography (CT). CT correctly diagnosed 21 of 22 surgically proved traumatic sesions of the spleen (96%). Twenty-seven patients had no evidence of splenic injury. This was confirmed at operation in 1 patient and clinical follow-up in 26. There were one false negative and one false positive. In 5 patients (10%), CT demonstrated other clinically significant lesions, including hepatic or renal lacerations in 3 and large retroperitoneal hematomas in 2. In adolescents and adults, CT is an accurate, noninvasive method of rapidly diagnosing splenic trauma and associated injuries. Further experience is needed to assess its usefulness in evaluating splenic injuries in infants and small children.

    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

    A marked change toward a more conservative approach in the treatment of abdominal trauma has been noted, especially during the last decade. This change in regimen was first seen in the handling of splenic trauma, initiated by pediatric surgeons. Later, the concept of conservative management was also introduced among adults and it is now widely accepted. Here, an almost mandatory splenectomy has been replaced by attempts at various forms of splenic salvage. The development followed an initial report by King and Shumacker in 1952 on an increased susceptibility to overwhelming sepsis in splenectomized children, findings which later also were demonstrated among adults. It has also been shown that the bleeding from intraparenchymal lesions with an intact splenic capsule or minor capsular tears frequently ceases spontaneously, hereby making nonoperative management possible in selective cases.

    Abdominal trauma from blunt objects remains a challenge in clinical practice. The primary aims are quick recognition and reversal of life-threatening situations, rational use of the available diagnostic methods, and avoidance of unnecessary laparotomy. The majority of these injuries can now be treated conservatively, whereby interventional methods such as drainage inserts and embolisation are becoming increasingly favoured. Observation of the treatment course by an experienced surgeon is a must. In patients with complicated injuries, special attention must be paid to so-called missed injuries: traumata that may be overlooked such as small intestine and diaphragm ruptures. Aside from retaining organs and their function, the most important concern is damage control (for complex injuries) and laparotomy in the abdominal compartment, with the application of temporary laparotomy as needed. These methods are aimed at reducing mortality pre- and post-admittance. However, we still lack valid prognostic parameters to allow realistic estimation of survival following severe, blunt abdominal trauma. PMID:15843910

    Mandibular trauma is a common problem seen by plastic surgeons. When fractures occur, they have the ability to affect the patient's occlusion significantly, cause infection, and lead to considerable pain. Interventions to prevent these sequelae require either closed or open forms of reduction and fixation. Physicians determining how to manage these injuries should take into consideration the nature of the injury, background information regarding the patient's health, and the patient's comorbidities. Whereas general principles guide the management of the majority of injuries, special consideration must be paid to the edentulous patient, complex and comminuted fractures, and pediatric patients. These topics are discussed in this article, with a special emphasis on pearls of mandibular trauma management. PMID:22550460

With current management options, the majority of hemodynamically stable patients with renal injuries can be successfully managed nonoperatively. Improved radiographic techniques and the development of a validated renal injury scoring system have led to improved staging of injury severity that is relatively easy to monitor.

    This is a retrospective study on the outcome using the TRISS methodology of 94 significantly injured patients over a 24-month period, managed by the Hospital Trauma Team in a general hospital since the formation of the Team in August 1994. There were 37 deaths and nine (24.3%) of these were 'potentially preventable' according to TRISS methodology. Seven of these nine 'potentially preventable or unexpected deaths' were transferred from a nearby district hospital where there was no acute operative facilities. There was no significant difference between the sex, age, mode of injury or Injury Severity Score between the direct admission and transfer-in cases and the M-statistic values of the two groups were similar. Five of the nine deaths happened in the first 4 months after the formation of the Trauma Team and the other four were scattered in the subsequent 20 months. The rate of preventable deaths was 50% (five out of 10 deaths) in the first 4 months, and was 15% (four out of 26) in the subsequent period. The probable causes for the 'potentially preventable trauma deaths' were delay owing to interhospital transfer, delay in activation of the trauma team, unidentified intra-peritoneal haemorrhage, failure to control haemorrhage and delayed or inadequate definitive operation. The evident improvement in the reduction of unexpected trauma deaths were likely associated with the success factors of the improvement of the multi-disciplinary cooperation including mutual understanding, simultaneous patient assessment, higher readiness to use diagnostic peritoneal lavage or ultrasonography to evaluate blunt abdominal trauma, earlier senior participation in patient care, shortening in response time of supportive facilities and a gradual cultural change towards dedicated trauma patient care. Further reduction in unexpected deaths can be expected if better prehospital triage by ambulance staff is attained to transfer trauma patients to the most appropriate instead of the nearest

    This review of early care covers issues pertaining to the analysis of system function, prehospital intravascular volume replacement, diagnosis of proximity vascular injury, the role of emergency thoracotomy, and the value of transesophageal echocardiography. The first six articles deal with various aspects of system function, from triage to analysis of outcome. The next series of articles reviews work in progress evaluating optimal fluid for resuscitation. Hypertonic saline and dextran combinations have been shown to restore vital signs better than isotonic solutions; they are safe, require smaller volumes, and may improve head injury outcome. Danger lies in the restoration of perfusion without hemorrhage control. Two articles on emergency thoracotomy review the indications and outcome in blunt and penetrating trauma. Survival in blunt trauma is virtually zero. An article and two editorials summarize state of the art for diagnosis and treatment of proximity vascular injury. Two articles describe the potential use of the new technique of transesophageal echocardiography. This new modality has not formed a solid indication at present and can be considered investigational in trauma care. PMID:7584006

    Joseph Beuys was one of the most significant artists of the 20th century. He was a gunner and radio operator in the German Air Force during World War II, and was severely injured several times. In March 1943 he had a life-changing experience after the dive bomber he was assigned to crashed in the Crimean peninsula. This trauma influenced Beuys' entire artistic career, and is known in art history as the 'Tartar Legend' or 'Tartar Myth'. Profoundly affected by the crash, the severe trauma, the near-death experience and his rescue, which he perceived as a "rebirth", Beuys no longer saw himself, other people or society as a whole in the same way as previously. With his new consciousness, he ignored boundaries and created visions whereby all mankind could experience the healing he had undergone. Beuys did not bring society far enough for the turning point towards "the healing of the world" to be visible, yet today it is important to keep his work alive as a record of his extraordinary strength, which arose from trauma and severe injury, and was carried by a passionate commitment to mankind and to life itself.

    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

    Introduction Evidence-based recommendations can be made with respect to many aspects of the acute management of the bleeding trauma patient, which when implemented may lead to improved patient outcomes. Methods The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing guidelines for the management of bleeding following severe injury. Recommendations were formulated using a nominal group process and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) hierarchy of evidence and were based on a systematic review of published literature. Results Key recommendations include the following: The time elapsed between injury and operation should be minimised for patients in need of urgent surgical bleeding control, and patients presenting with haemorrhagic shock and an identified source of bleeding should undergo immediate surgical bleeding control unless initial resuscitation measures are successful. A damage control surgical approach is essential in the severely injured patient. Pelvic ring disruptions should be closed and stabilised, followed by appropriate angiographic embolisation or surgical bleeding control, including packing. Patients presenting with haemorrhagic shock and an unidentified source of bleeding should undergo immediate further assessment as appropriate using focused sonography, computed tomography, serum lactate, and/or base deficit measurements. This guideline also reviews appropriate physiological targets and suggested use and dosing of blood products, pharmacological agents, and coagulation factor replacement in the bleeding trauma patient. Conclusion A multidisciplinary approach to the management of the bleeding trauma patient will help create circumstances in which optimal care can be provided. By their very nature, these guidelines reflect the current state-of-the-art and will need to be updated and revised as important new evidence becomes available. PMID:17298665

    A cardio-embolic stroke as a sequela of remote blunt chest trauma is a rare clinical presentation. Blunt chest trauma can cause various acute cardiac complications like arrhythmias, cardiac contusion etc. However, delayed consequences such as left ventricular thrombus resulting in thromboembolic phenomena are reported infrequently. A 30-year-old healthy man presented to an outside facility with transient neurological deficits. An MRI brain showed lesions suggestive of embolic etiology. A trans-thoracic echocardiogram (TTE) showed a 1.5 × 1.5 cm mass present in the left ventricular (LV) apex. Patient was transferred to our institution for cardiac surgery evaluation. On detailed questioning, he reported an incident of blunt chest trauma during a martial arts exhibition fight that took place 2 years back. Given this history, a cardiac catheterization was done, which showed 30% stenosis in mid-left anterior descending artery (LAD) without any other significant obstructive lesion. A trans-esophageal echocardiogram (TEE) showed akinesis of the LV apex and confirmed TTE finding of a mass, consistent with an apical thrombus. Surgery was deferred and patient was started on anticoagulation. A cardiac MRI done 2 weeks later showed evidence of apical infarction in the LAD territory. LAD is the most commonly affected coronary vessel by blunt traumatic injuries, likely due to its vulnerable anatomical position on the anterior aspect of the heart. A variety of mechanisms including intimal tear, rupture and spasm have been implicated in the pathogenesis of myocardial infarction after blunt chest trauma. PMID:24023477

    Traumatic brain injuries are often followed by abnormal hyperexcitability, leading to acute seizures and epilepsy. Previous studies documented the rewiring capacity of neocortical neurons in response to various cortical and subcortical lesions. However, little information is available on the functional consequences of these anatomical changes after cortical trauma and the adaptation of synaptic connectivity to a decreased input produced by chronic deafferentation. In this study, we recorded intracellular (IC) activities of cortical neurons simultaneously with extracellular (EC) unit activities and field potentials of neighboring cells in cat cortex, after a large transection of the white matter underneath the suprasylvian gyrus, in acute and chronic conditions (at 2, 4, and 6 weeks) in ketamine-xylazine-anesthetized cats. Using EC spikes to compute the spike-triggered averages of IC membrane potential, we found an increased connection probability and efficacy between cortical neurons weeks after cortical trauma. Inhibitory interactions showed no significant changes in the traumatized cortex compared with control. The increased synaptic efficacy was accompanied by enhanced input resistance and intrinsic excitability of cortical neurons, as well as by increased duration of silent network periods. Our electrophysiological data revealed functional consequences of previously reported anatomical changes in the injured cortex. We suggest that homeostatic synaptic plasticity compensating the decreased activity in the undercut cortex leads to an uncontrollable cortical hyperexcitability and seizure generation. PMID:18596152

    Malignancy is a common cause of disseminated intravascular coagulation and usually presents as a chronic disorder in solid organ tumours. We present a rare case of recurrent acute disseminated intravascular coagulation in neuroendocrine carcinoma after manipulation, firstly, by core biopsy and, later, by cytotoxic therapy causing a release of procoagulants and cytokines from lysed tumour cells. This is reminiscent of tumour lysis syndrome where massive quantities of intracellular electrolytes and nucleic acid are released, causing acute metabolic imbalance and renal failure. This case highlights the potential complication of acute disseminated intravascular coagulation after trauma to malignant cells. PMID:23139666

    Poor psychological outcomes are common among trauma survivors, yet not all survivors experience adverse sequelae. The current study examined links between cumulative trauma exposure as a function of the level of betrayal (measured by the relational closeness of the survivor and the perpetrator), trauma appraisals, gender, and trauma symptoms. Participants were 273 college students who reported experiencing at least one traumatic event on a trauma checklist. Three cumulative indices were constructed to assess the number of different types of traumas experienced that were low (LBTs), moderate (MBTs), or high in betrayal (HBTs). Greater trauma exposure was related to more symptoms of depression, dissociation, and PTSD, with exposure to HBTs contributing the most. Women were more likely to experience HBTs than men, but there were no gender differences in trauma-related symptoms. Appraisals of trauma were predictive of trauma-related symptoms over and above the effects explained by cumulative trauma at each level of betrayal. The survivor's relationship with the perpetrator, the effect of cumulative trauma, and their combined impact on trauma symptomatology are discussed. PMID:23542882

    Impaired neck muscle function leads to disability in individuals with chronic whiplash-associated disorder (WAD), but diagnostic tools are lacking. In this study, deformations and deformation rates were investigated in five dorsal neck muscles during 10 arm elevations by ultrasonography with speckle tracking analyses. Forty individuals with chronic WAD (28 women and 12 men, mean age = 37 y) and 40 healthy controls matched for age and sex were included. The WAD group had higher deformation rates in the multifidus muscle during the first (p < 0.04) and 10th (only women, p < 0.01) arm elevations compared with the control group. Linear relationships between the neck muscles for deformation rate (controls: R(2) = 0.24-0.82, WAD: R(2) = 0.05-0.74) and deformation of the deepest muscles (controls: R(2) = 0.61-0.32, WAD: R(2) = 0.15-0.01) were stronger for women in the control group versus women with WAD, indicating there is altered interplay between dorsal neck muscles in chronic WAD.

    This case report describes the diagnosis and management of a 43-year-old female patient who had sustained an injury to her neck in a motor-vehicle accident two years earlier. The major symptoms described by the patient included headache and neck pain, but history and examination also revealed signs and symptoms potentially indicative of cervical artery compromise. Physical therapy management initially consisted of soft tissue and non-thrust joint manipulation of the lower cervical and thoracic spine, specific exercise prescription, and superficial heat. Cervical vascular compromise was re-evaluated by way of the sustained extension-rotation test. When at the fifth visit this test no longer produced symptoms potentially indicative of vascular compromise, upper cervical diagnosis and management consisting of soft tissue and non-thrust joint manipulation was added. A positive outcome was achieved both at the impairment level and with regard to limitations in activities, the latter including increased performance at work, a return to previous reading activities, improved length and quality of sleep, and greater comfort while driving. At discharge, the patient reported only occasional pain and mild limitations in activities. This report describes the positive outcomes in a patient with chronic whiplash syndrome; however, its main emphasis lies in the discussion and critical evaluation of clinical reasoning in the presence of diagnostic uncertainty with regard to cervical artery compromise.

    Neck proprioception is one of the information sources that helps regulate postural balance. However, it is believed to be impaired as patients with both idiopathic neck pain (INP) and whiplash-associated disorders (WAD) have been shown to have a more unstable balance than healthy controls. This systematic review aims to determine if there are significant differences in balance between patients with INP and healthy controls and between patients with WAD and healthy controls. Studies were sought from PubMed, Cinahl, Physiotherapy Evidence Database, Web of Science, Academic Search Complete, Science Direct, and Scielo. Two reviewers independently screened titles and abstracts, assessed full reports for potentially eligible studies, and extracted information on participants' characteristics, pain characteristics, study methods, study results, and study quality. Twelve studies were included in this systematic review. Of these, six compared INP and healthy controls and eight compared WAD and healthy controls. All but one study (11/12) found a statistically significant difference for at least one measurement between patients with INP and WAD and healthy controls. The results of this systematic review suggest that both patients with INP and patients with WAD have poorer balance than healthy controls. PMID:22515180

    2009-06-01

    Several cases of appendicitis after blunt abdominal trauma have been reported in the literature. A 41-year-old man on a cruise ship began to experience acute abdominal pain several hours after cliff diving from a 20-ft height and landing hard against the water on his right side. The patient's symptoms were treated and he remained on the ship until its scheduled arrival in port 2 days later. In the emergency department, a bedside extended Focused Assessment with Sonography in Trauma (eFAST) examination showed no evidence of free fluid in the abdominal cavity, pericardial effusion, or pneumothorax. Next, an ultrasound of the right lower quadrant was performed, which revealed a 1.06 cm, noncompressible appendix consistent with appendicitis. Although physical examination remains the gold standard for evaluation of the acute abdomen, the presentation of acute appendicitis is historically unreliable and delays in its diagnosis can result in significant increases in morbidity and mortality. Ultrasonography has been shown to have clear value in the evaluation of the acute abdomen. It is the authors' opinion that ultrasonography may have an unrealized potential as a diagnostic tool for traumatic appendicitis in the trauma bay and as a triage tool for the cruise ship physician who must evaluate a patient with traumatic abdominal pain and determine the need for medical evacuation.

    Background Water-soluble components in mesenteric lymph have been implicated in the pathophysiology of acute lung injury and distal organ failure following trauma and haemorrhagic shock. Proteomics analyses have recently shown similarities and specificities of post-trauma/haemorrhagic shock lymph and plasma. We hypothesise that the metabolic phenotype of post-trauma/haemorrhagic shock mesenteric lymph and plasma share common metabolites, but are also characterised by unique features that differentiate these two fluids. Materials and methods Matched samples were collected from 5 brain-dead organ donors who had suffered extreme trauma/haemorrhagic shock. Metabolomics analyses were performed through ultra-high performance liquid chromatography mass spectrometry. Results Overall, 269 metabolites were identified in either fluid. Despite significant overlapping, metabolic phenotypes of matched lymph or plasma from the same patients could be used to discriminate sample fluid or biological patient/traumatic-injury origin. Metabolites showing relatively high levels in both fluids included markers of haemolysis and cell lysis secondary to tissue injury. Discussion High positive correlations were observed between the quantitative levels of markers of systemic metabolic derangement following traumatic/haemorrhagic hypoxaemia, such as succinate, oxoproline, urate and fatty acids. These metabolites might contribute to coagulopathies of trauma and neutrophil priming driving acute lung injury. Future studies will investigate whether the observed compositional specificities mirror functional or pathological adaptations after trauma and haemorrhage. PMID:27177401

    2014-11-01

    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

    Almost 1 out of every 3 homeless women (32%) in the United States, United Kingdom, and Australia has experienced childhood sexual trauma. We assessed lifetime sexual trauma histories among 29 homeless women from three Southern California community sites: one residential safe house and two safe parking areas. More than half of the women (54%) reported a history of sexual trauma. That rate was higher (86%) among women living at the safe home than among women staying at the safe parking sites (only 42%). All four of the women who had served in the military reported having experienced military sexual trauma. The high percentages of sexual trauma found in homeless women highlight the need for effective interventions for sexual trauma. PMID:26583457

    This study examines primary (resulting from blast wave) and secondary (resulting from disintegrated, penetrating fragments) blast trauma to the skeleton. Eleven pigs were exposed to semi-controlled blast events of varying explosive type, charge size, and distance, including some cases with shrapnel. Skeletal trauma was found to be extensive, presenting as complex, comminuted fractures with numerous small, displaced bone splinters and fragments. Traumatic amputation of the limbs and cranium was also observed. Fractures were concentrated in areas nearer the blast, but there was generally no identifiable point of impact. Fractures were more random in appearance and widespread than those typically associated with gunshot or blunt force injury events. These patterns appear to be uniquely associated with blast trauma and may therefore assist forensic anthropologists and other forensic examiners in the interpretation of skeletal trauma by enabling them to differentiate between blast trauma and trauma resulting from some other cause.

    The ability of paramedics to deliver advanced trauma life support (ATLS) in an expedient fashion for victims of trauma has been strongly challenged. In this study, the records of 114 consecutive victims of blunt trauma who underwent laparotomy or thoracotomy were reviewed. Prehospital care was rendered by paramedics operating under strict protocols. The mean response time (minutes +/- SEM) to the scene was 5.6 +/- 0.27. On-scene time was 13.9 +/- 0.62. The time to return to the hospital was 8.0 +/- 0.4. On-scene time included assessing hazards at the scene, patient extrication, spine immobilization (n = 98), application of oxygen (n = 94), measurement of vital signs (n = 114), splinting of 59 limbs, and the following ATLS procedures: endotracheal intubation (n = 31), IV access (n = 106), ECG monitoring (n = 69), procurement of blood for tests including type and cross (n = 58), and application of a pneumatic antishock garment (PASG) (n = 31). On-scene times were analyzed according to the number of ATLS procedures performed: insertion of one IV line (n = 46), 14.8 +/- 1.03 minutes; two IV lines (n = 28), 13.4 +/- 0.92; one IV line plus intubation (n = 7), 14.0 +/- 2.94; two IV lines plus intubation (n = 9), 17.0 +/- 2.38; and two IV lines plus intubation plus PASG (n = 13), 12.4 +/- 1.36. Of the 161 IV attempts, 94% were completed successfully. Of 36 attempts at endotracheal intubation, 89% were successful.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3826807

    Objective: To assess the availability of trauma care services in a district referral hospital of Southern India. Methods: This was a cross-sectional study being performed during 2013 in a tertiary healthcare centre in Southern Indian. A detailed assessment of trauma care services was done in a 400 bed speciality hospital which is an apex referral hospital in the public health system using a check list based on WHO guidelines for evaluation of essential trauma care services, along with in-depth interviews of hospital stake holders and key informants. Results: The hospital had physical infrastructure in terms of emergency room, inpatient wards, operation theatres, intensive care unit and blood bank facilities. The recently constructed designated building for trauma care services was not operational and existing facilities were used beyond capacity. A designated trauma team was lacking and speciality services for managing polytrauma were deficient and thus, existing personnel were performing multiple tasks. Neurosurgeons and rehabilitative nursing staff were unavailable, and a radiographer was not available on a 24/7 basis. Existing nursing personnel had not received any formal training in trauma care and standard operating protocols were not available for trauma care. Resources for acute resuscitation were partially adequate. The hospital lacked adequate resources to manage head, abdomen, chest and spine injuries, and most of the polytrauma cases were referred to nearby city hospitals. Conclusion: District hospital, the only referral hospital in public health system for trauma victims of that region, had inadequate resources to manage trauma victims, which was probably responsible for delay in trauma care, improper referrals, high cost of care and poor outcomes.

    2014-01-01

    Background The chronic course of whiplash-associated disorder (WAD) has implications for both the individual and society. It has been shown that up to 50% of patients have not yet returned to work six months after a whiplash injury. We wanted to study the return-to-work (RTW) process in individuals sick-listed for more than eight weeks in six Danish municipalities. RTW in individuals sick-listed due to WAD was compared to that in those sick-listed for other musculoskeletal disorders (MSD). Methods Information about long-term sick-listed individuals in six Danish municipalities was retrieved from an existing database. Data on public transfer income were collected and the RTW process was followed on a weekly basis. Multivariate logistic regression analysis of RTW was done four times during the first three years after the start of sick-listing. Results One hundred and four individuals were sick-listed due to WAD and 3,204 individuals were sick-listed due to other MSDs. After 6 months, the RTW was significantly lower in the WAD group. OR for RTW in the WAD group was 0.29 (0.18–0.49) compared to the MSD group. The RTW process for both groups stabilised after two years of follow-up; 44% returned to work in the WAD group as compared to 58% in the MSD group. Conclusion Sick-listed individuals with whiplash-associated disorder are less likely to return to work than individuals who are sick-listed because of other musculoskeletal disorders. In both groups, RTW stabilised after two years of follow-up. PMID:24495801

    Based on crew resource management of the airline industry the German Society for Trauma Surgery (Deutsche Gesellschaft für Unfallchirurgie, DGU) was the first scientific community in Germany to develop and implement a training course for patient safety. The S:training courses contain four course formats which focus on the prehospital life support (S:PLS), the operating room (S:OR), the trauma room (S:TR) and the intensive care unit (S:ICU). In the training the importance of the human factor for the management of acute major trauma is developed by means of presentations, training videos, practical training, discussions and realistic case scenarios associated with the special working environment of the participants. A specially developed course manual acts as a work and reference book and course booking is possible at http://www.safe-trac.de. PMID:19644664

    The management of acute trauma in the pregnant patient relies on a thorough understanding of the underlying physiology of pregnancy. This issue reviews the evidence regarding important considerations in pregnant trauma patients, including the primary and secondary survey as well as the possibility for Rh exposure, placental abruption, uterine rupture, and the need for a prompt perimortem cesarean section in the moribund patient. Because ionizing radiation is always a concern in pregnancy, the circumstances where testing provides benefits that outweigh risks to the fetus are discussed. Emergency clinicians are encouraged to advocate for trauma prevention, including proper safety restraints for motor vehicles and screening for domestic violence, as these measures have been shown to be effective in reducing morbidity and mortality in this population. Recommendations for monitoring, admission, discharge, and follow-up are also noted. PMID:23847860

    In this article we present how the consultation-liaison and psychology divisions of an academic medical center's Department of Psychiatry responded in the first week after the Boston Marathon bombings, specifically in the context of disaster response guidelines and evidence-based approaches to acute trauma. Since the department had to address several complicated matters at multiple levels within the hospital system, we highlight unexpected issues unique to this particular event as they arose within the primary domains of our involvement. This article aims to (1) provide a descriptive analysis of how we enacted disaster and trauma guidelines and evidence-based care within a hospital setting, (2) shed light on the unique and unexpected administrative and systemic issues encountered in our response, and (3) discuss lessons learned, including opportunities to improve trauma-related care.

    In last 20 years a progressive increase in the cases of road traffic accidents is seen in the institution. In this study efforts have been made to study epidemiology of trauma & how to help the trauma victims in a better way. To study the changing trends in incidence & presentation of trauma victims. To recommend preventive measures based on the analysis. The present study was carried out in MGIMS, Sewagram, Wardha from 2001 to 2003. For this study which is retrospective and prospective, a total of 986 cases of surgical trauma were studied. Present study showed that in this rural area accidents account for maximum trauma admissions & major trauma only in 20 %. Out of 986 patients, 78.8 % required repair of wounds, 3.8 % required exploratory laparotomy and 16.3 % had orthopedic interventions. Overall mortality rate was 2.9 %. It was found that general care in wards was good in terms of trauma results of rural areas. These results may vary when compared with specialized trauma centers in cities; however after a period of few years cost effectiveness of trauma centers in terms of benefits needs an assessment*.

    Childhood psychic trauma appears to be a crucial etiological factor in the development of a number of serious disorders both in childhood and in adulthood. Like childhood rheumatic fever, psychic trauma sets a number of different problems into motion, any of which may lead to a definable mental condition. The author suggests four characteristics related to childhood trauma that appear to last for long periods of life, no matter what diagnosis the patient eventually receives. These are visualized or otherwise repeatedly perceived memories of the traumatic event, repetitive behaviors, trauma-specific fears, and changed attitudes about people, life, and the future. She divides childhood trauma into two basic types and defines the findings that can be used to characterize each of these types. Type I trauma includes full, detailed memories, "omens," and misperceptions. Type II trauma includes denial and numbing, self-hypnosis and dissociation, and rage. Crossover conditions often occur after sudden, shocking deaths or accidents that leave children handicapped. In these instances, characteristics of both type I and type II childhood traumas exist side by side. There may be considerable sadness. Each finding of childhood trauma discussed by the author is illustrated with one or two case examples. PMID:1824611

    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.

    Eight-hundred thirty-three members of an ethnically diverse longitudinal cohort study in Hawaii were surveyed about their personal exposure to several types of traumatic events, socioeconomic resources, and mental health symptoms. Results replicated findings from prior research that while men and women are exposed to similar rates of trauma overall, women report more exposure to traumas high in betrayal (HB), while men report exposure to more traumas lower in betrayal (LB). Trauma exposure was predictive of mental health symptoms, with neglect, household dysfunction, and HB traumas predicting symptoms of depression, anxiety, PTSD, dissociation, and sleep disturbance, and LB traumas predicting PTSD and dissociation symptoms. Native Hawaiian ethnicity and poorer socioeconomic status were predictive of greater trauma exposure and symptoms. Results suggest that more inclusive definitions of trauma are important for gender equity, and that ethnic group variation in symptoms is better explained by factors such as differential trauma exposure and economic and social status differences, rather than minority status per se.

    The medical and surgical care of obese trauma patients presents a variety of unique and important challenges. Over the past 30 years, this population has increased dramatically in number, and the optimization of their care demands the attention of the medical community. The problems of caring for an obese trauma patient begin before the actual traumatic event occurs due to their substantially higher incidence of serious comorbidities, such as diabetes mellitus, hypertension, and cardiopulmonary issues. In the setting of trauma, important considerations for the obese patient include careful and expeditious preoperative medical optimization; appropriate deep vein thrombosis prophylaxis; planning for and preventing operative and postoperative challenges (eg, pulmonary and wound complications); and ensuring adequate hospital equipment and staffing resources in the acute and rehabilitative phases of care. This article outlines the scope of the obesity epidemic, reviews the medical consequences of obesity, and highlights surgical considerations specific to the care of orthopedic injuries in the obese trauma patient.

  2. Thrombelastography (TEG®): practical considerations on its clinical use in trauma resuscitation

    PubMed Central

    2013-01-01

    Background Thrombelastography is a laboratorial test that measures viscoelastic changes of the entire clotting process. There is growing interest in its clinical use in trauma resuscitation, particularly for managing acute coagulopathy of trauma and assisting decision making concerning transfusion. This review focuses on the clinical use of thrombelastography in trauma, with practical points to consider on its use in civilian and military settings. Methods A search in the literature using the terms “thrombelastography AND trauma” was performed in PUBMED database. We focused the review on the main clinical aspects of this viscoelastic method in diagnosing and treating patients with acute coagulopathy of trauma during initial resuscitation. Results Thrombelastography is not a substitute for conventional laboratorial tests such as INR and aPTT but offers additional information and may guide blood transfusion. Thrombelastography can be used as a point of care test but requires multiple daily calibrations, should be performed by trained personnel and its technique requires standardization. While useful partial results may be available in minutes, the whole test may take as long as other conventional tests. The most important data provided by thrombelastography are clot strength and fibrinolysis. Clot strength measure can establish whether the bleeding is due to coagulopathy or not, and is the key information in thrombelastography-based transfusion algorithms. Thrombelastography is among the few tests that diagnose and quantify fibrinolysis and thus guide the use of anti-fibrinolytic drugs and blood products such as cryoprecipitate and fibrinogen concentrate. It may also diagnose platelet dysfunction and hypercoagulability and potentially prevent inappropriate transfusions of hemostatic blood products to non-coagulopathic patients. Conclusions Thrombelastography has characteristics of an ideal coagulation test for use in early trauma resuscitation. It has limitations

    The growing popularity of nonoperative treatment of children with splenic injuries has seduced some physicians into a false sense of security regarding care of the injured child. Although it has been established that hemodynamically stable children with splenic, hepatic, and even renal injuries can safely be treated "expectantly," this concept cannot be applied indiscriminately. Accurate diagnosis and effective care of the child with blunt abdominal trauma is an exercise of clinical precision that demands attention to detail and thorough evaluation. This review addresses this process in light of recent advances in diagnostic imaging and in consideration of recent reports analyzing different protocols for therapeutic decision making.

    Treatment of polytrauma patients remains a medical as well as socioeconomic challenge. Although diagnostics and therapy improved during the last decades, multiple injuries are still the major cause of fatalities in patients below 45 years of age. Organ dysfunction and organ failure are major complications in patients with major injuries and contribute to mortality during the clinical course. Profound understanding of the systemic pathophysiological response is crucial for innovative therapeutic approaches. Therefore, experimental studies in various animal models are necessary. This review is aimed at providing detailed information of common trauma models in small as well as in large animals. PMID:21331361

    Merrick, Mark A.

    2002-01-01

    Objectives: To revisit the secondary injury model, to incorporate several current pathophysiologic theories into the model, and to show the need for more direct research examining the model. Data Sources: I searched MEDLINE and CINAHL from 1976 to 2001 for literature related to acute injury pathology and pathophysiology and selected classic articles and pathology, pathophysiology, and immunology texts. Data Synthesis: Acute musculoskeletal injury management is based on a pathophysiologic model, often referred to as the secondary injury model, which was originally developed more than 25 years ago. In this model, acute trauma is referred to as primary injury, whereas secondary injury refers to damage to otherwise uninjured cells that was a direct consequence of the physiologic response to primary injury. In the original model, mechanisms for secondary injury were hypothesized based on then-contemporary understandings of immunology and cellular pathology. These mechanisms were broadly categorized as either enzymatic or hypoxic. Since this time, the pathologic paradigms for cell death from trauma have evolved, and the secondary injury model requires some updating. Some controversy now exists regarding the categorization of injury as primary or secondary, specifically whether posttraumatic damage is actually secondary injury in previously uninjured tissue or delayed death of primary injured cells. Similarly, the postulated mechanisms that lead to secondary injury now appear to be considerably more complex than originally anticipated. Conclusions/Recommendations: The secondary injury model has been reconciled with our contemporary understanding of pathophysiology. Specifically, secondary hypoxic injury has been clarified to be secondary ischemic injury, and several specific mechanisms for ischemic injury have been identified. Similarly, secondary injury from mitochondrial failure and other potential mechanisms has been identified, and the role and interaction of these

    56 patients at the age of 18-60 years with severe trauma were examined. Influence of the polyelectrolytic (Reamberin)solution on an acid-base state, osmolarity and electrolytic composition of plasma in the acute posttraumatic period was evaluated. It was found that patients, who was treated by isotonic sodium chloride solution and Ringer's solution, had metabolic acidosis and hyperchloremia. In contrast, in the reamberin group 82% of patients had lower concentrations of chloride and had nothing acid-base disturbances on the second day after trauma. Reamberin didn't influence on plasma osmolarity and the rate of metabolic alkalosis during the acute period of a trauma. PMID:27025136

    2015-01-01

    Vicarious trauma (VT), the phenomenon of changes in cognition and worldview that result from empathic response and repeated exposure to narratives of trauma, is a risk for helping professionals. This descriptive, correlational study sought to examine levels of VT among sexual assault nurse examiners (SANEs) as compared with other women's health nurses. It also explored whether levels of VT are different for nurses who have experienced primary trauma alone, VT alone, or both personal trauma and VT. VT was assessed through an anonymous online survey using the nurses' total scores on the Trauma and Attachment Belief Scale. Trauma and Attachment Belief Scale scores were significantly higher for SANEs (M = 178.5, SD = 42.6) than for women's health nurses (M = 168.1, SD = 41.4; p = 0.025), indicating higher levels of trauma-related cognitive disruption in the SANE group. Scores were also significantly higher for both groups with personal trauma histories at the p < 0.05 level compared with the women's health nurses with no personal history. SANEs who had no personal history of trauma did not differ significantly from either group of nurses who did, suggesting that VT from working as an SANE is associated with levels of cognitive disruption similar to oneself having experienced trauma. Nurses should be aware of this phenomenon and its sequelae when choosing to pursue the specialty of sexual assault nursing. Hospitals and other organizations employing SANEs should also be aware of VT and provide a support system with resources in place to mitigate these effects. Future research should further explore effects of primary trauma versus VT, clinical manifestations and significance of varying levels of VT, and interventions and strategies for dealing with VT.

    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

    The first report of acute respiratory distress syndrome (ARDS) was published in 1967, and even now acute lung injury (ALI) and ARDS are severe forms of diffuse lung disease that impose a substantial health burden all over the world. Recent estimates indicate approximately 190,000 cases per year of ALI in the United States each year, with an associated 74,500 deaths per year. Common causes of ALI/ARDS are sepsis, pneumonia, trauma, aspiration pneumonia, pancreatitis, and so on. Several pathologic stages of ALI/ARDS have been described: acute inflammation with neutrophil infiltration, fibroproliferative phase with hyaline membranes, with varying degrees of interstitial fibrosis, and resolution phase. There has been intense investigation into the pathophysiologic events relevant to each stage of ALI/ARDS, and much has been learned in the alveolar epithelial, endobronchial homeostasis, and alveolar cell immune responses, especially neutrophils and alveolar macrophages in an animal model. However, these effective results in the animal models are not equally adoptive to those in randomized, controlled trials. The clinical course of ALI/ARDS is variable with the likely pathophysiologic complexity of human ALI/ARDS. In 1994, the definition was recommended by the American-European Consensus Conference Committee, which facilitated easy nomination of patients with ALI/ARDS for a randomized, clinical trial. Here, we review the recent randomized, clinical trials of ALI/ARDS. PMID:19420806

    The Afghanistan conflict has resulted in a large number of service personnel sustaining amputations. Whilst obvious differences exist between military and civilian trauma-related amputations both settings result in life changing injuries. Comparisons offer the potential of advancement and protection of the knowledge gained during the last 12 years. This paper compares the military and civilian trauma-related amputee cohorts' demographics, management and rehabilitation outcomes measures. The UK military Joint Theatre Trauma Registry and a civilian major trauma centre database of trauma-related amputees were analysed. 255 military and 24 civilian amputees were identified. A significant difference (p>0.05) was seen in median age (24, range 18-43, vs. 48, range 24-87 years), mean number of amputations per casualty (1.6±SD 0.678 vs. 1±SD 0.0), mean ISS (22±SD 12.8 vs. 14.7±SD 15.7) and gender (99% males vs. 78%). Rehabilitation outcome measures recorded included the Special Interest Group in Amputee Medicine score where the military group demonstrated significantly better scores (91% Grade E+ compared to 19%). Differences in patients underlying physiology and psychology, the military trauma system and a huge sustained investment in rehabilitation are all contributing factors for these differing outcomes. However the authors also believe that the use of a consultant-led MDT and central rehabilitation have benefited the military cohort in the acute rehabilitation stage and is reflected in the good short-term outcomes.

    The inter-rater reliability of the Injury Severity Score (ISS) and the Polytraumaschlüssel (PTS) [multiple trauma code] was studied using diagnosis sheets filled in for 107 multiple injured patients. The scoring was performed by eight physicians with different levels of qualification. The scores for individual patients varied widely depending on the scorer, with extremes differing from the mean by about 80% and 70% for the ISS and PTS, respectively. The mean ISS and PTS for the whole study population also varied significantly between the scorers (P less than 0.0001, one-way analysis of variance). Raters with experience in trauma scoring calculated significantly higher scores (P less than 0.01, t-test) Neither the ISS nor the PTS seem reliable enough to describe injury severity in an individual patient. Treatment decisions must not be based on such grounds. Even for larger groups, caution must be exercised in comparison of different populations of multiple traumatized patients. PMID:1570531

    The temporal bones are paired structures located on the lateral aspects of the skull and contribute to the skull base. Trauma is usually the result of blunt head injury and can result in damage to the brain and meninges, the middle and internal ear, and the facial nerve. Complications can include intracranial hemorrhage, cerebral contusion, CSF leak and meningitis, hearing loss, vertigo, and facial paralysis. To prevent these complications, diagnosis followed by appropriate medical and surgical management is critical. Diagnosis relies primarily on physical signs and symptoms as well as radiographic imaging. Emergent intervention is required in situations involving herniation of the brain into the middle ear cavity or hemorrhage of the intratemporal carotid artery. Patients with declining facial nerve function are candidates for early surgical intervention. Conductive hearing loss can be corrected surgically as an elective procedure, while sensorineural hearing loss carries a poor prognosis, regardless of management approach. Children generally recover from temporal bone trauma with fewer complications than adults and experience a markedly lower incidence of facial nerve paralysis. PMID:22110824

    In the United States, trauma is the leading cause of death among those who are 1-44 years old, with cardiovascular injuries representing the second most common cause of traumatic death after central nervous system injuries. Evaluation of trauma patients with suspected cardiac injury may be complex and include electrocardiography, measurement of cardiac biomarkers, and imaging examinations. Contrast material-enhanced computed tomography (CT) has become one of the most valuable imaging tools available for evaluating hemodynamically stable patients with suspected cardiac injury. The presence of hemopericardium, with or without cardiac tamponade, is one of the most significant findings of cardiac injury. Other complications that result from blunt cardiac injury, such as pericardial rupture and cardiac herniation, may be readily depicted at multidetector CT. Assessment of patients with cardiac injuries, particularly those with penetrating injuries, is a challenging and time-critical matter, with clinical and imaging findings having complementary roles in the formation of an accurate diagnosis. Patients who are hemodynamically stable, particularly those with penetrating cardiac injuries, also may benefit from a timely imaging examination. In addition to chest radiography, other available modalities such as transthoracic and transesophageal echocardiography, nuclear medicine, and magnetic resonance imaging may play a role in selected cases.

    In recent decades, acoustic shock and explosion traumas have increased in frequency in the general population. 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.

    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

    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

    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

    Study Design Secondary analysis of a randomized clinical trial. Background Patient perception of the benefits gained from treatment is important, yet satisfaction with the outcome of treatment for chronic whiplash-associated disorders (WADs) has not been investigated. Objectives To investigate whether satisfaction with the outcome of treatment for chronic WAD changed over time, and whether there were group differences. Methods Two hundred sixteen people with chronic WAD (66% women; mean age, 40.4 years) participated in a 3-month program of physical therapist-led neck-specific exercises with or without a behavioral approach, or received a prescription of general physical activity. The main outcome was satisfaction with the outcome of treatment, assessed at baseline and 3, 6, and 12 months later. Additional outcomes were enablement and expectation fulfillment. Results Satisfaction improved over time in the 3 groups (odds ratio = 1.15; 95% confidence interval: 1.10, 1.20; P<.001). There was a significant group-by-time interaction (P<.001), with increased odds of being satisfied in the groups receiving neck-specific exercises compared to general physical activity. Enablement increased after completion of the intervention in all groups (P<.001). People who received neck-specific exercises reported greater enablement and expectation fulfillment than people prescribed general physical activity (P<.01). Conclusion Exercise interventions for chronic WAD led to increased satisfaction for 12 months following treatment that was unrelated to the type of exercise intervention received.

    Background: Whiplash-Associated Disorders (WAD) are common following a motor vehicle accident. The Functional Impairment Test - Hand, and Neck/Shoulder/Arm (FIT-HaNSA) assesses upper extremity physical performance. It has been validated in patients with shoulder pathology but not in those with WAD. Objectives: Establish the Intra and inter-rater reliability and the known-group and construct validity of the FIT-HaNSA in patients with Grade II WAD (WAD2). Methods: Twenty-five patients with WAD2 and 41 healthy controls were recruited. Numeric Pain Rating Scale (NPRS), Neck Disability Index (NDI), Disabilities of the Arm, Shoulder and Hand (DASH), cervical range of motion (CROM), and FIT-HaNSA were completed at two sessions conducted 2 to 7 days apart by two raters. Intraclass correlation coefficients (ICC) were used to describe Intra and inter-rater reliability. Spearman rank correlation coefficients (ρ) were used to quantify the associations between scores of the FIT-HaNSA and other measures in the WAD2 group (convergent construct validity). Results: The Intra and inter-ICCs for the FIT-HaNSA scores ranged from 0.88 to 0.89 in the control group and 0.78 to 0.85 in the WAD2 group. Statistically significant differences in FIT-HaNSA performance between the two groups suggested known group construct validity (P < 0.001). The correlations between the NPRS, NDI, DASH, CROM and FIT-HaNSA were generally poor (ρ < 0.4). Conclusion: The study results indicate that the total FIT-HaNSA score has good Intra and inter-rater reliability and the construct validity in WAD2 and healthy controls. PMID:27350797

    The case of a 46-year-old man complaining of acute abdominal discomfort is presented. The patient fell 3 ft and injured his abdomen in the right upper quadrant four days before his emergency department visit. The complete workup revealed an acutely ruptured middle colic artery. The presenting symptoms, laboratory work, differential diagnosis, computed tomography scan, treatment, and follow-up are reviewed. This case is unusual in that delayed rupture of the middle colic artery secondary to blunt abdominal trauma had not been described previously. PMID:1554184

    Ethnoracial minority status contributes to an increased risk for posttraumatic stress disorder (PTSD) after trauma exposure, beyond other risk factors. A population-based sampling frame was used to examine the associations between ethnoracial groups and early PTSD symptoms while adjusting for relevant clinical and demographic characteristics. Acutely injured trauma center inpatients (N = 623) were screened with the PTSD Checklist. American Indian and African American patients reported the highest levels of posttraumatic stress and preinjury cumulative trauma burden. African American heritage was independently associated with an increased risk of higher acute PTSD symptom levels. Disparities in trauma history, PTSD symptoms, and event related factors emphasize the need for acute care services to incorporate culturally competent approaches for treating these diverse populations.

    The treatment of acute lung injury and septic complications after blunt chest trauma remains a challenge. Inhaled hydrogen sulfide (H₂S) may cause a hibernation-like metabolic state, which refers to an attenuated systemic inflammatory response. Therefore, we tested the hypothesis that inhaled H₂S-induced suspended animation may attenuate the inflammation after pulmonary contusion. Male Sprague-Dawley rats were subjected to blunt chest trauma (blast wave) or sham procedure and subsequently exposed to a continuous flow of H₂S (100 ppm) or control gas for 6 h. Body temperature and activity were measured by an implanted transmitter. At 6, 24, or 48 h after trauma, animals were killed, and the cellular contents of bronchoalveolar lavage (BAL) as well as cytokine concentrations in BAL, plasma, and culture supernatants of blood mononuclear cells, Kupffer cells, splenic macrophages, and splenocytes were determined. Hydrogen sulfide inhalation caused a significant reduction in body temperature and activity. The trauma-induced increase in alveolar macrophage counts was abrogated 48 h after trauma when animals received H₂S, whereas the trauma-induced increase in neutrophil counts was unaltered. Furthermore, H₂S inhalation partially attenuated the mediator release in BAL and culture supernatants of Kupffer cells as well as splenic cells; it altered plasma cytokine concentrations but did not affect the trauma-induced changes in mononuclear cell culture supernatants. These findings indicate that inhaled H₂S induced a reduced metabolic expenditure and partially attenuated inflammation after trauma. Nevertheless, in contrast to hypoxic- or pathogen-induced lung injury, H₂S treatment appears to have no protective effect after blunt chest trauma. PMID:22089191

    The Diagnostic and Statistical Manual of Mental Disorders 5 (DSM-5) includes a distinct diagnostic group of trauma and stressor-related disorders that has been set apart from anxiety disorders. From a perspective of adult psychiatry this new disorder category includes posttraumatic stress disorder (PTSD), acute stress disorder (ASD), and adjustment disorders. The PTSD is based on narrower trauma criteria that focus on acute life-threatening situations, serious injury, or sexual violence by way of direct confrontation, witnessing or indirect confrontation. Indirect confrontation, however, is reserved only for violent or accidental events that occurred to close family members or friends. The former A2 criterion of an intense emotional reaction to trauma has been removed. A deliberately broad approach to clinical PTSD phenomenology has created an empirically driven new cluster of persistent negative alterations in cognition and mood due to experiencing traumatic events. The ASD has been reconceptualized as an intense stress syndrome with a clear need of acute treatment during the early course after traumatic exposure. Adjustment disorders continue to emphasize maladaptive emotional and behavioral responses to unspecific, non-traumatic stressors in an intensity that is beyond social or cultural norms. Neither complex PTSD nor prolonged grief disorders have received an independent diagnostic status within DSM-5. With respect to stress-related disorders major divergences between DSM-5 and the future International Classification of Diseases 11 (ICD-11) are to be expected. PMID:24728766
