    Full Text Available Tinnitus has been suggested to arise from neuronal hyperactivity in auditory areas of the brain and anti-epileptic drugs are sometimes used to provide relief from tinnitus. Recently, the anti-epileptic properties of the cannabinoid drugs have gained increasing interest; however, the use of cannabinoids as a form of treatment for tinnitus is controversial. In the present study, we tested whether a combination of delta-9-tetrahydrocannabinol (delta-9-THC and cannabidiol (CBD, delivered in a 1:1 ratio, could affect tinnitus perception in a rat model of acoustic trauma-induced tinnitus. Following sham treatment or acoustic trauma, the animals were divided into the following groups: 1 sham (i.e. no acoustic trauma with vehicle treatment; 2 sham with drug treatment (i.e. delta-9-THC + CBD; 3 acoustic trauma-exposed exhibiting tinnitus, with drug treatment; and 4 acoustic trauma-exposed exhibiting no tinnitus, with drug treatment. The animals received either the vehicle or the cannabinoid drugs every day, 30 min before the tinnitus behavioural testing. Acoustic trauma caused a significant increase in the auditory brainstem response (ABR thresholds in the exposed animals, indicating hearing loss; however, there was a partial recovery over 6 months. Acoustic trauma did not always result in tinnitus; however among those that did exhibit tinnitus, some of them had tinnitus at multiple frequencies while others had it only at a single frequency. The cannabinoids significantly increased the number of tinnitus animals in the exposed-tinnitus group, but not in the sham group. The results suggest that cannabinoids may promote the development of tinnitus, especially when there is pre-existing hearing damage.

    Full Text Available Abstract Introduction A continuous process of trauma centre evaluation is essential to ensure the development and progression of trauma care at regional, national and international levels. Evaluation may be by comparison between pooled datasets or by direct benchmarking between centres. This study attempts to benchmark mortality at two trauma centres standardising this for multiple case-mix factors, which includes the prevalence of individual background pre-existing diseases within the study population. Methods Trauma patients with an Injury Severity Score (ISS >15 admitted to the two centres in 2001 and 2002 were included in the study with the exception of those who died in the emergency department. Patient characteristics were analysed in terms of 18 case-mix factors including Glasgow Coma Scale on arrival, Injury Severity Score and the presence or absence of 9 co-morbidity types, and patient outcome was compared based on in-hospital mortality before and after standardisation. Results Crude mortality was greater at UHNS (18.2 vs 14.5% with a non-significant odds ratio of 1.31 prior to adjusting for case-mix (P = 0.171. Adjustment for case mix using logistic regression analysis altered the odds ratio to 1.64, which was not significant (P = 0.069. Discussion This study did not demonstrate any significant difference in the outcome of patients treated at either hospital during the study period. More importantly it has raised several important methodological issues pertinent to researchers undertaking registry based benchmarking studies. Data at the two registries was collected by personnel with differing backgrounds, in formats that were not completely compatible and was collected for patients that met different admissions criteria. The inclusion of a meaningful analysis of pre-existing disease was limited by the availability of robust data and sample size. We suggest greater communication between trauma research coordinators to ensure equivalent

    A total of 160 patients underwent emergency room thoracotomy (ERT) from January 1988 to June 1995. There were 142 male and 18 female patients with ages ranging from 15 months to 72 years old with a mean age of 31 years. Blunt trauma was the mechanism of injury in 11 patients; none of them survived, and they were excluded from further analysis. A total of 149 patients sustained penetrating trauma, 111 patients gunshot wounds, and 38 patients stab wounds. A total of four patients survived to discharge for an overall survival rate of 2.7 per cent. All four were victims of a stab wound and were neurologically intact at the time of discharge. Special interest was placed in classifying patients according to their physiologic status both at the scene and on arrival to the emergency department. Class I, patients with no signs of life; Class II, Agonal--patients in electromechanical dissociation/pulseless electrical activity with no palpable pulse or blood pressure; Class III, Profound Shock--patients with blood pressure less than 60 mm Hg; and Class IV, Mild Shock--patients with blood pressure between 60 and 90 mm Hg. 122 patients (89%) fitted the criteria for Scene Classes I and II. None of these patients improved or responded to prehospital resuscitation to be moved up to Emergency Department Classes III or IV, and all of them died. Of the four survivors, three were in Scene Class III and one was in Scene Class IV. This study confirms a previous report that, overall, ERT has a very low survival rate. ERT should be abandoned in patients sustaining blunt trauma, and should probably be limited to patients sustaining penetrating chest injuries who fall into the physiologic Classes III or IV at the scene.

    Background Africa has 4% of the global vehicles but accounts for about one tenth of global vehicular deaths. Major trauma in Kenya is associated with excess mortality in comparison with series from trauma centers. The determinants of this mortality have not been completely explored. Objectives To determine the factors affecting mortality among road users in Nairobi, Kenya. Methods Cross-sectional study of prospectively collected data of trauma admissions at the Kenyatta National Hospital over a calendar year (2009–2010). Information collected included age, gender, road user type, principal anatomical region of injury, admission status, admission blood pressure and GCS, disposition destination, Injury Severity Score (ISS), injuries sustained, treatment and mortality at two weeks. Major or severe injury was defined as injuries of ISS > 15. Groups based on in-hospital survival were compared using determinants of mortality using X2 or students t-test as appropriate. Logistic regression was used to assess the independence of predictive variables. Results One thousand six hundred forty seven (1647) patients were admitted for trauma during the study period. Traffic admissions were 1013 (61.7%) and males predominated (79.8%). The average age of patients admitted was 31.7 years. Pedestrians, vehicle occupants and motorcyclists represented 43.3%, 27.2% and 15.2% of the road users injured. The proportion of patients with ISS > 15 was 10.9%. The overall mortality was 7.7%. Mortality for ISS > 15 was 27.6%. The following factors significantly predicted mortality on univariate analysis: head injury, abdominal injury, transfer in status, blood transfusion, ICU admission, age > 60 years, Glasgow coma scale (GCS) and injury severity.

    Studies have demonstrated the value of the follow-up skeletal survey in identifying additional fractures, clarifying indeterminate findings, and improving dating of skeletal injuries in victims of physical abuse. To determine whether a more limited follow-up survey could yield the same radiologic data as a full follow-up survey. The study cohort comprised 101 children who had follow-up surveys that met our inclusion criteria. Consensus readings of both original and follow-up surveys were performed by two pediatric radiologists. These results were compared to determine additional findings from the follow-up surveys. Limited skeletal survey protocols were evaluated to determine whether they would detect the same fractures seen with a complete osseous survey. In the 101 children 244 fractures were identified on the initial osseous survey. Follow-up surveys demonstrated new information in 38 children (37.6%). A 15-view limited follow-up survey identified all additional information seen on the complete follow-up survey. Our data demonstrate that a 15-view limited follow-up skeletal survey could be performed without missing clinically significant new fractures and still allow proper identification of confirmed fractures or normal findings. A limited survey would decrease radiation dose in children. (orig.)

    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

    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.

  1. Abdominal trauma

    International Nuclear Information System (INIS)

    Radiologic evaluation of abdominal trauma must provide a quick and accurate assessment of the lesions in order to improve the management of the patient. The technique used varies depending on the mechanism of the trauma (blunt trauma or stab wounds) and the hemodynamic status. Radiologic evaluation is usually performed in blunt trauma whereas stab wound trauma is usually explored surgically. The various techniques available are standard radiographs, ultrasonography, computed tomography and arteriography. The role of magnetic resonance imaging in the immediate evaluation is still not well defined. It appears to be useful method in the delayed evaluation of diaphragmatic trauma. Computed tomography is the method most commonly performed in trauma patients. This technique is accurate and allows correct assessment of the lesions. The disadvantages are the radiation induced and the need for a hemo-dynamically stable patient. The aim of the radiologic evaluation is to provide the clinicians with an accurate description of the lesions. It can help in the management of the patient usually in association with clinical and laboratory data. It can also guide interventional procedures (drainage, embolization...). Finally, it allows radiographic follow-up when conservative treatment is performed. (authors). 26 refs., 11 figs., 1 tab

  2. Abdominal trauma

    International Nuclear Information System (INIS)

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

  3. The PPARbeta/delta agonist GW0742 relaxes pulmonary vessels and limits right heart hypertrophy in rats with hypoxia-induced pulmonary hypertension.

    Directory of Open Access Journals (Sweden)

    Louise S Harrington

    Full Text Available BACKGROUND: Pulmonary vascular diseases are increasingly recognised as important clinical conditions. Pulmonary hypertension associated with a range of aetiologies is difficult to treat and associated with progressive morbidity and mortality. Current therapies for pulmonary hypertension include phosphodiesterase type 5 inhibitors, endothelin receptor antagonists, or prostacyclin mimetics. However, none of these provide a cure and the clinical benefits of these drugs individually decline over time. There is, therefore, an urgent need to identify new treatment strategies for pulmonary hypertension. METHODOLOGY/PRINCIPAL FINDINGS: Here we show that the PPARbeta/delta agonist GW0742 induces vasorelaxation in systemic and pulmonary vessels. Using tissue from genetically modified mice, we show that the dilator effects of GW0742 are independent of the target receptor PPARbeta/delta or cell surface prostacyclin (IP receptors. In aortic tissue, vascular relaxant effects of GW0742 were not associated with increases in cGMP, cAMP or hyperpolarisation, but were attributed to inhibition of RhoA activity. In a rat model of hypoxia-induced pulmonary hypertension, daily oral dosing of animals with GW0742 (30 mg/kg for 3 weeks significantly reduced the associated right heart hypertrophy and right ventricular systolic pressure. GW0742 had no effect on vascular remodelling induced by hypoxia in this model. CONCLUSIONS/SIGNIFICANCE: These observations are the first to show a therapeutic benefit of 'PPARbeta/delta' agonists in experimental pulmonary arterial hypertension and provide pre-clinical evidence to favour clinical trials in man.

    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

    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.

  6. Transfusion practices in trauma

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

Consequently, all patients should be evaluated radiologically after blunt chest trauma to allow timely and appropriate treatment. Conventional chest radiographs and computed tomography (CT) are proven modalities with which to evaluate patients after blunt chest trauma. Over the last several years extended focused assessment with sonography for trauma (eFAST) has gained increasing importance for the initial assessment of seriously injured patients. In the acute phase of severely injured patients eFAST examinations are helpful to exclude pneumothorax, hemothorax and hemopericardium. Chest radiographs may also be used to diagnose a pneumothorax or hemothorax; however, the sensitivity is limited and CT is the diagnostic modality of choice to evaluate severely injured 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

  10. Abdominal trauma

    International Nuclear Information System (INIS)

    The potential for multiple intraperitoneal and retroperitoneal organ injuries often makes accurate clinical evaluation of abdominal trauma patients difficult. Additionally, patients may be unresponsive, have unreliable abdominal physical examinations, or have concurrent serious head and cervical spine injuries which delay diagnosis of and attention to abdominal problems. In these situations radiologic abdominal imaging is often requested. To expedite patient evaluation, close cooperation between the emergency physician and the radiologist is essential. It is the clinical stability of the traumatized patient that dictates the extent of radiologic imaging. Life-threatening hypotension, positive peritoneal signs, or clear evidence of penetrating abdominal injury are indications for immediate surgery. Stable patients with signs suggesting intra-abdominal injury will benefit by further radiologic evaluation with appropriate imaging modalities. The selection of an appropriate modality in any one clinical situation depends upon many criteria including accessibility to diagnostic equipment, the sensitivity and specificity of each technique, and the expertise and preference of the attending radiologist. A suggested scheme for evaluating abdominal trauma patients is presented. Most aspects of this evaluation scheme will be discussed in depth

    There is growing acknowledgment that research in the postconflict field needs to include a focus on social conditions. The authors applied structural equation modeling to epidemiologic data obtained from postconflict Timor-Leste, to examine for links involving potentially traumatic events and sociodemographic factors (age, gender, educational levels, and unemployment) with psychological symptoms and functioning. Exposure to trauma and lack of education emerged as most relevant with psychological distress impacting on education in the urban area. Age and gender exerted influences at different points in the model consistent with the known history of Timor. Although based on cross-sectional data, the model supports the relevance of past trauma, posttraumatic distress, and postconflict social conditions to functioning in societies such as Timor-Leste.

    Full Text Available Abstract Background Trauma is one of the leading causes of death in young adult patients. Many pre-clinical and clinical studies attempt to investigate the immunological pathways involved, however the true mediators remain to be elucidated. Herein, we attempt to describe the immunologic response to systemic trauma in the context of the Danger model. Data Sources A literature search using PubMed was used to identify pertinent articles describing the Danger model in relation to trauma. Conclusions Our knowledge of Danger signals in relation to traumatic injury is still limited. Danger/alarmin signals are the most proximal molecules in the immune response that have many possibilities for effector function in the innate and acquired immune systems. Having a full understanding of these molecules and their pathways would give us the ability to intervene at such an early stage and may prove to be more effective in blunting the post-injury inflammatory response unlike previously failed cytokine experiments.

    BACKGROUND: Severe paediatric trauma is rare, and pre-hospital and local hospital personnel experience with injured children is often limited. We hypothesised that a higher proportion of paediatric trauma victims were taken to the regional trauma centre (TC). METHODS: This is an observational...... follow-up study that involves one level I TC and seven local hospitals. We included paediatric (trauma patients with a driving distance to the TC > 30 minutes. The primary end-point was the proportion of trauma patients arriving in the TC. RESULTS: We included 1934...... trauma patients, 238 children and 1696 adults. A total of 33/238 children (13.9%) vs. 304/1696 adults (17.9%) were transported to the TC post-injury (P = 0.14). Among these, children were significantly less injured than adults [median Injury Severity Score (ISS) 9 vs. 14, P

    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

    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

  18. Interdisciplinary shock-room care: tasks for the radiologist from the viewpoint of the trauma surgeon

    International Nuclear Information System (INIS)

    Efficient resuscitation of major trauma requests an interdisciplinary communication between trauma surgeons, anaesthesiologists and radiologists. Trauma outcome is significantly influenced by horizontal trauma team organisation and coherence to clinical algorithms, which allow fast diagnosis and intervention. A radiologist present on patients arrival in the trauma room provides a major impact on trauma care. Nevertheless optimal integration in the trauma team implies profound knowledge of the priorities of advanced trauma life support and trauma algorithms. His or her involvement is not limited to patient care only, also active participation in trauma room design, interdisciplinary algorithm development and trauma research are essential tasks for radiologists devoted to emergency radiology. Based on the pathophysiology of polytrauma and the structure of German trauma system, current concepts and proven clinical algorithms with special regard to the radiologist and his duties and tasks will are presented.

  4. Renal trauma in adults - a pictorial review

    International Nuclear Information System (INIS)

    Full text: This review provides a framework for understanding the classification and features of renal trauma. Computed tomography (CT) is now the modality of choice in prompt diagnosis and staging of renal trauma. A retrospective review of the CT scans of all patients with blunt abdominal trauma sustaining renal injury that presented to our hospital within the last 2 years was undertaken. The patient list was obtained from our Trauma Registry database at the Trauma Services Unit. Representative cases of each category of renal injury are displayed on a poster, accompanied by explanatory notes. We also reviewed the literature on renal trauma between 1985-2001 on Medline. The indications for radiological assessment and the management of renal trauma remain controversial. Staging of renal trauma with CT imaging, when integrated with clinical information helps to facilitate appropriate management plan. Renal injuries are classified into four grades on the basis of imaging: - Grade 1: Minor cortical contusion, minor laceration with limited perinephric hematoma, and small cortical infarct. - Grade 2: Major renal lacerations extending to the medulla with or without involvement of the collecting system and segmental renal infarct. - Grade 3: Catastrophic injury which include multiple renal lacerations and injury to the renal vascular pedicle. - Grade 4: Ureteropelvic junction injuries. Diagnostic imaging and staging plays a major role in assessing patients with renal injuries and affects clinical management decisions. Understanding the radiologic classification of traumatic renal injuries and integrating the findings with clinical information assist in developing an optimal management plan.

  6. Urogenital trauma: imaging upper GU trauma

    International Nuclear Information System (INIS)

    Objectives: This article will define the current controversies and concepts in the classification, clinical presentation, imaging approaches and management of upper urinary tract trauma. Materials and methods, results: This review will include the experience of the authors in the field of renal trauma over a 32-year period. Current thinking accepts the view that significant renal trauma is generally present when there is gross hematuria, signs of shock, or other clinical signs of severe injury. In most patients, suspected renal injury will be evaluated as a part of the overall assessment of the patient for suspected intraperitoneal injury. The authors will stress some exceptions to the rule. Conclusions: Most trauma experts now advocate conservative management, unless the patient is unstable or a renal vascular thrombosis or avulsion is suspected. Similarly, penetrating trauma to the kidney in and of itself no longer requires mandatory surgery. In the United States, computed tomography (CT), especially spiral CT, is considered the best diagnostic study, if available. Intravenous pyelography (IVP) is adequate if this is the only imaging modality available and if no concomitant injuries to the abdominal structure are suspected. Ultrasound, although strongly advocated in some countries, can lead to some significant false negatives. The diagnosis and management of unusual problems such as the traumatic AV fistula, the patient with an absent kidney or injury to the congenitally abnormal kidney, the serendipitous renal tumor in a patient with trauma, or serious bleeding after an apparent minor injury (i.e., spontaneous hemorrhage) are also reviewed in this article

    Duodenal trauma is uncommon but nowadays seen more and more frequently due to the increased automobile accidents and violent events. The management of duodenal trauma can be complicated, especially when massive injury to the pancreatic-duodenal-biliary complex occurs simultaneously. Even the patients receive surgeries in time, multiple postoperative complications and high mortality are common. To know and manage duodenal trauma better, we searched the recent related literature in PubMed by the keywords of duodenal trauma, therapy, diagnosis and abdomen. It shows that because the diagnosis and management are complicated and the mortality is high,duodenal trauma should be treated in time and tactfully.And application of new technology can help improve the management. In this review, we discussed the incidence,diagnosis, management, and complications as well as mortality of duodenal trauma.

    Konstantinidis, I; Malliari, H; Metaxas, S

    2011-01-01

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

    2016-01-01

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

    2011-01-01

    Full Text Available Gonadotropin-releasing hormone (GnRH agonists are derived from native GnRH by amino acid substitution which yields the agonist resistant to degradation and increases its half-life. The hypogonadotropic hypogonadal state produced by GnRH agonists has been often dubbed as "pseudomenopause" or "medical oophorectomy," which are both misnomers. GnRH analogues (GnRH-a work by temporarily "switching off" the ovaries. Ovaries can be "switched off" for the therapy and therapeutic trial of many conditions which include but are not limited to subfertility, endometriosis, adenomyosis, uterine leiomyomas, precocious puberty, premenstrual dysphoric disorder, chronic pelvic pain, or the prevention of menstrual bleeding in special clinical situations. Rapidly expanding vistas of usage of GnRH agonists encompass use in sex reassignment of male to female transsexuals, management of final height in cases of congenital adrenal hyperplasia, and preserving ovarian function in women undergoing cytotoxic chemotherapy. Hypogonadic side effects caused by the use of GnRH agonists can be tackled with use of "add-back" therapy. Goserelin, leuprolide, and nafarelin are commonly used in clinical practice. GnRH-a have provided us a powerful therapeutic approach to the treatment of numerous conditions in reproductive medicine. Recent synthesis of GnRH antagonists with a better tolerability profile may open new avenues for both research and clinical applications. All stakeholders who are partners in women′s healthcare need to join hands to spread awareness so that these drugs can be used to realize their full potential.

  2. The coagulopathy of trauma.

    Science.gov (United States)

    Maegele, M

    2014-04-01

    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

    Blunt renal trauma is the third most common injury in abdominal trauma following splenic and hepatic injuries, respectively. In the majority, such injuries are associated with other abdominal organ injuries. As urological injuries are not usually life-threatening, and clinical signs and symptoms are non-specific, diagnosis is often delayed. We present a practical approach to the diagnosis and management of these injuries based on our experience in a busy inner city trauma hospital with a review of the current evidence-based practice. Diagnostic imaging signs are illustrated.

  5. Trauma of the midface

    2015-12-01

    Full Text Available 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.

  6. Development of a radioreceptor assay for β2 adrenergic agonists

    International Nuclear Information System (INIS)

    Several β2 adrenergic agonists are illegally used as growth promoters in meat production. We have developed and evaluated a radioreceptor assay for the multianalyte detection of these compounds. The method is based on a competition for binding with receptors (plasma membranes prepared from bovine teat muscles) between a radioactive tracer (3H-dihydroalprenolol) and β2 agonist residues present in the samples. The method has been validated for three β2 agonists (clenbuterol, mabuterol and cimaterol) in bovine urine samples. The detection limit (mean of ''blank'' values + 3 SEM) in urine was 2.4 ppb clenbuterol. Using this procedure, samples containing at least 5 ppb of clenbuterol, mabuterol or cimaterol could be identified as positive for the presence of β2 agonists. (orig.)

    Measurement of trauma center performance presently relies on W-score calculation and comparison to national data sets. A limitation to this practice is a skewing of the W score, as it determines overall performance of a trauma population that is often heavily weighted by patients of low acuity. The University of Virginia relative mortality metric (RMM) was formulated to provide higher resolution in identifying areas of performance improvement within subpopulations of a trauma center using traditional Trauma Injury Severity Score methodology. Lactic acidosis has been established as a risk factor for mortality in the setting of trauma. This study aims to compare survival margin, defined as the area between actual and predicted mortality curves, in patients with either normal or elevated initial lactate. W score and RMM were calculated and compared in these cohorts. Whereas the W score suggested increased survival within the high initial lactate group, the RMM demonstrated the expected finding of increased survival margin in the normal lactate cohort. The RMM is a potentially valuable tool for trauma centers to monitor and improve performance. In addition, these findings validate the use of lactate as a triage and risk adjustment tool in the trauma setting. PMID:27457866

    Full Text Available O crescimento populacional de idosos, associado a uma forma de vida mais saudável e mais ativa, deixa este grupo de pessoas mais exposto ao risco de acidentes. Em alguns países, o trauma do idoso responde por uma elevada taxa de mortalidade, a qual se apresenta de forma desproporcionalmente maior do que a observada entre a população de adultos jovens. Tal fato acarreta um grande consumo de recursos financeiros destinados à assistência da saúde e um elevado custo social. As características fisiológicas próprias do idoso, assim como a presença freqüente de doenças associadas, faz com que estes pacientes se comportem diferentemente e de forma mais complexa do que os demais grupos etários. Estas particularidades fazem com que o atendimento ao idoso vítima de trauma se faça de forma diferenciada. A presente revisão aborda aspectos da epidemiologia, da prevenção, da fisiologia, do atendimento e da reabilitação do idoso vítima de trauma.The populational growth of the elderly, associated to a healthier and more active life, make this group of people more exposed to accidents. In some countries, trauma in the elderly is responsible for a high mortality rate, desproportionately higher than in the adults.

The distinct physiologic characteristics of the elderly and the frequent presence of associated diseases make that these patients behave diferently and in a more complex way than patients of other ages. These particularities make that health care to the elderly victims of trauma have to be different. The present revision is about aspects of epidemiology, prevention, physiology, health care and reabilitation of the elderly victims of trauma.

    Acute coagulopathy of trauma predicts a poor clinical outcome. Tissue trauma activates the sympathoadrenal system resulting in high circulating levels of catecholamines that influence hemostasis dose-dependently through immediate effects on the two major compartments of hemostasis, i.......e., the circulating blood and the vascular endothelium. There appears to be a dose-dependency with regards to injury severity and the hemostatic response to trauma evaluated in whole blood by viscoelastic assays like thrombelastography (TEG), changing from normal to hypercoagulable, to hypocoagulable and finally......, is an evolutionary developed response that counterbalances the injury and catecholamine induced endothelial activation and damage. Given this, the rise in circulating catecholamines in trauma patients may favor a switch from hyper- to hypocoagulability in the blood to keep the progressively more procoagulant...

    1987-11-01

    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

  16. CT of abdominal trauma

    International Nuclear Information System (INIS)

    Soon after it became available for clinical use, cranial CT became the method of choice for evaluating head trauma. Only relatively recently have newer generation full-body scanners been installed at major trauma centers, but experience is rapidly being gained in the utilization of CT for abdominal trauma. CT has proved highly accurate in diagnosing a wide variety of injuries to both intra- and retroperitoneal organs in pediatric and adult patient populations. The impact has been evident not only in decreasing utilization of other diagnostic tests, such as angiography, but also in practical management decisions, such as whether to perform exploratory laparotomy. This chapter details the authors' approach to evaluation of abdominal trauma by CT

    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.

  4. Imaging of thoracic trauma

    International Nuclear Information System (INIS)

    Blunt trauma to the chest results from transfer of kinetic energy to the human body. It may cause a wide range of mostly life-threatening injuries, including fractures of the thoracic skeleton, disintegration of the pleural space, contusion or laceration of pulmonary parenchyma and damage to the mediastinal structures. For a systematic approach it may be helpful to follow an organ-based evaluation of thoracic trauma. However, it should be borne in mind that subtle injuries may be associated with serious complications. Trauma to the chest may affect different anatomic compartments at the same time, requiring and extending diagnostic approach. Conventional radiography plays a major role in diagnosting thoracic trauma, complemented by ultrasound examination of the pleura and abdomen. It is well documented that CT scanning represents a major technological improvement for assessment of thoracic trauma. With the advent of fast helical CT scanning this method becomes more applicable for severly traumatized patients and potentially replaces other time-consuming procedures. State-of-the-art imaging of both projection and cross-sectional techniques provides useful information for immediate and appropriate treatment mandatory in patients with thoracic trauma. (orig.)

  7. Patterns of ocular trauma

    International Nuclear Information System (INIS)

    To describe the patterns of ocular trauma, cause of injury and its effects on eye. A retrospective case series. Medical records of 1105 patients admitted with ocular trauma were reviewed. The details of patients regarding age, gender, literacy, cause of injury and its effects on eye were entered into specially-designed performa. Sample selection consisted of all patients with history of ocular trauma and who were admitted to hospital. Population details consisted patients who were referred to the hospital from all parts of N.W.F.P. Thus, the frequency of trauma in the hospital admissions was analysed. Ophthalmic trauma comprised 6.78% of the hospital admission. One thousand one hundred and five patients presented with eye injuries. Out of them, 21 patients suffered from trauma to both eyes. Almost 80% patients were male and 69% patients were below 30 years of age. Delayed presentation was more common and 63.61% patients presented after one week. Open globe injuries were more common (520 eyes (46.18%)) than closed globe injuries (484 eyes (42.98%)). 23.26% of open globe injuries were associated with intraocular and intra-orbital foreign bodies. Superficial non-perforating, eyelid and adnexal and burns were seen in 122 eyes (10.83%). Among the complications, lens damage and hyphema was seen in more than 50% of the patients, 16.60% eyes were infected at the time of admission and 4.88% of eyes needed enucleation or evisceration. The common causes of injury were violence in 37.37%, occupational in 24.43% and domestic accidents in 19.18%. Ophthalmic trauma is a major public health problem. Majority of the involved are male and under 30 years of age. Delayed presentation is more common. Open globe injuries are more frequent. Violence and occupational injuries are the major causes.

    2007-01-01

    Full Text Available Trauma is the most common non-obstetrical cause of death in pregnant women. Pregnancy must always be suspected in any female trauma patient of childbearing age until proved otherwise. Unique changes in anatomy and physiology that takes place during pregnancy alter the pathophysiology and location of maternal injuries in pregnancy, which may be significantly different from the non-pregnant state. Trauma from road traffic accidents, falls and domestic violence are the most common causes of abdominal blunt trauma. As pregnancy progresses, the change of accidental injury increases. Head and neck injuries, respiratory failure, and hypovolemic shock constitute the most frequent causes of trauma related maternal death in pregnancy. Even the pregnant woman with minor injuries should be carefully observed. Initial management is directed at resuscitation and stabilization of the mother that takes precedence over that of the fetus, unless vital signs cannot be maintained and perimortem cesarean section decided upon. Fetal monitoring should be maintained after satisfactory resuscitation and stabilization of the mother. Preventive measures include proper seat belt use and identifying and counseling victims of suspected domestic violence.

    2016-07-01

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

    Objective: The high burden of injuries in Iran necessitates the establishment of a comprehensive trauma care system. The purpose of this paper is to describe the current status of trauma system regarding the components and function. Methods: The current status of trauma system in all components of a trauma system was described through expert panels and semi-structured interviews with trauma specialists and policy makers.Results: Currently, various organizations are involved in prevention, management and rehabilitation of injuries,but an integrative system approach to trauma is rather deficient. There has been ongoing progress in areas of public education through media, traffic regulation reinforcement,hospital care and prehospital services. Meanwhile, there are gaps regarding financing, legislations and education of high risk groups. The issues on education and training standards of the front line medical team and continuing education and evaluation are yet to be addressed. Trauma registry has been piloted in some provinces, but as it needs the well-developed infrastructure (regarding staff, maintenance,financial resources), it is not yet established in our system of trauma care.Conclusions: It seems that one of the problems with trauma care in Iran is lack of coordination among trauma system organizations. Although the clinical management of trauma patients has improved in our country in the recent decade, decreasing the burden of injuries necessitates an organized approach to prevention and management of trauma in the context of a trauma system.

    2012-01-01

    Objective This study analyzed predictors of post-traumatic stress disorder (PTSD) in civilian trauma victims to assess how peritraumatic dissociation (PD) relates to PTSD symptom development. We examined PD and PTSD symptoms from a prior trauma simultaneously to better understand the extent to which past and current reactions to a trauma can predict the development of PTSD for a current trauma. Methods Participants (N=48) were recruited from the emergency department (ED) of a large, southeastern hospital and assessed immediately after a trauma and again at 4 weeks and 12 weeks post-trauma. We used both self-report and interviewer-based questionnaires to assess PD and PTSD symptoms for prior and current trauma. Results A hierarchical linear regression revealed that at 4-week follow up, when controlling for several demographic variables and trauma type, a model including both PD and PTSD symptoms from a prior trauma significantly predicted PTSD outcome (F(47)= 3.70, p=0.00), with PD and prior PTSD symptoms significantly contributing 17% and 9% of variance respectively. At 12 weeks, PTSD symptoms from prior trauma (β=0.094, p=0.538) and PD (β=−0.017, p=0.909) did not account for a significant proportion of the variance in PTSD for the enrolling trauma. Conclusion Prior and current reactions to trauma are both important factors in predicting the development of PTSD symptoms to a current trauma. The more immediate measurement of PD during presentation to the ED may explain the strength of its relationship to PTSD symptom development. Furthermore, our findings support the use of PTSD symptoms of a past trauma, as opposed to trauma frequency, as a predictor of PTSD from a subsequent trauma. Methodological limitations and future directions are discussed. PMID:22900118

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

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

    Full Text Available Blood and blood components are considered drugs because they are used in the treatment of diseases. As with any drug, adverse effects may occur, necessitating careful consideration of therapy. Like any other therapeutic decision, the need for transfusion should be considered on the basis of risks and benefits and alternative treatments available to avoid over- and under-transfusion. This review is focused on the blood transfusion protocol in trauma patients with hemorrhagic shock. Besides, issues related to emergency and massive transfusion have also been elaborated. We conducted a comprehensive MEDLINE search and reviewed the relevant literature, with particular reference to emergency medical care in trauma.

    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.

  4. Skeleton scintigraphy in trauma

    International Nuclear Information System (INIS)

    Skeletal trauma is common and presents both an opportunity and a problem in skeletal scintigraphy. The opportunity arises in the ability of skeletal scintigraphy to demonstrate abnormalities early after direct trauma. It is well recognized that the early detection of fractures in some sites cannot be reliably achieved by standard radiography, especially in the femoral neck and scaphoid bone. The problem comes in recognizing the effects of skeletal trauma when using skeletal scintigraphy for another purpose, such as the detection of metastatic disease. iatrogenic trauma to either the skeleton or soft tissues may be manifest scintigraphic ally. For example Craniotomy typically leaves a rim pattern at the surgical margin. Rib Retraction during thoracotomy can elicit periosteal reaction. Areas of the skeletal receiving curative levels of ionizing radiation (typically 4000 rads or greater) characteristically demonstrate decreased uptake within 6 months to 1 year after therapy. The generally high sensitivity of the skeletal scintigraphy seems to make it an ideal survey test in cases of suspected child abuse especially in which radiographs are unrevealing. Because of difficulties in obtaining a history of trauma from a preschool child or even eliciting a satisfactory description of the location and nature of the pain, skeletal scintigraphy provides a simple and reliable investigation in these children. Subtle trauma, such as that from stress fractures is often difficult to visualize on a plain radiograph. Skeletal scintigraphy is frequently positive at the time of clinical presentation. Skeletal scintigraphy is exquisitely sensitive to the remodeling process and typically shows abnormalities 1 to 2 weeks or more before the appearance of radiographic changes in stress fractures. The periosteal reaction can be visualized within hours of the injury. Insufficiency and fatigue fractures such as vertebral compression fracture, which is probably the most common consequence of

    Dopamine (DA) agonists are playing increasingly important role in the treatment of not only advanced Parkinson′s disease (PD) and in PD patient with levodopa (L-DOPA)-induced motor fluctuations,but also in early treatment of the disease.This shift has been largely due to the demonstrated L-DOPA-sparing effect of DA agonists and their putative neuroprotective effect,based largely on experimental in vitro and in vivo studies.In this article we review the evidence of neuroprotection by DA agonists pramipexole,ropinirole,pergolide,bromocriptine and apomorphine in cell cultures and animal models of nigral injury.Most of the studies suggest that DA agonists exert their neuroprotection via directly scavenging free radicals or increasing the activities of radical-scavenging enzymes,and enhancing neurotrophic activity.The finding that pramipexole can normalize mitochondrial membrane potential and inhibit activity of caspase-3 in cytoplasmic hybrid cells made from mitochondrial DNA of nonfamilial Alzheimer′s disease patients,however,suggests even a broader implication for the neuroprotective role of DA agonists.Although the clinical evidence for neuroprotection by DA agonists is still limited,the preliminary results from several on-going clinical trials are promising.Several longitudinal studies are currently in progress designed to demonstrate a delay or slowing of progresion of PD using various surrogate markers of neuronal degeneration such as 18 F-L-DOPA PET and 123 I β-CIT SPECT.The results of these experimental and clinical studies will improve our understanding of the action of DA agonists and provide critical information needed for planning future therapeutic strategies in PD and related neurodegenerative disorders.``

    Full Text Available Background: Childhood trauma has become a major cause of mortality and morbidity, disability and socio-economic burden and it is expected by the World Health Organization (WHO that by 2020 it will be the number 1 disease globally. The WHO and UNICEF have published their third World Report on Child Injury Prevention in December 2008. Materials and Methods: A systematic review was performed on the history and magnitude of paediatric trauma worldwide. Additionally exciting developments and new trends were assessed and summarized. Results: Paediatric trauma is a growing field of clinical expertise. New developments include total body digital imaging of children presenting with polytrauma; targeted management of head injuries; conservative management of abdominal injuries in children and diagnostic laparoscopy, including the laparoscopic management of complications following the conservative management of solid organ injuries. Conclusion: Paediatric trauma has long been neglected by the medical profession. In order to deal with it appropriately, it makes sense to adopt the public health approach, requiring that we view child injuries similarly to any other disease or health problem. The greatest gain in our clinical practice with dealing with child injuries will result from a strong focus on primary (preventing the injury, secondary (dealing with the injury in the most efficient manner as well as tertiary prevention (making sure that children treated for trauma will be appropriately reintegrated within our society. By actively promoting child safety we will not only achieve a most welcome reduction in medical cost and disability, but also the ever-so-much desired decline of avoidable childhood misery and suffering.

    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.

Optimal timing of trauma alerts could improve team preparedness and performance while also limiting adverse ripple effects throughout the hospital. The purpose of this study was to evaluate how timing of trauma team activation and notification affects initial in-hospital management of trauma patients.Methods: Data from a single hospital trauma care quality registry were matched with data from a trauma team alert log. The time from patient arrival to chest X-ray, and the emergency department length of stay were compared with the timing of trauma team activations and whether or not trauma team members received a preactivation notification.Results: In 2009, the trauma team was activated 352 times; 269 times met the inclusion criteria. There were statistically significant differences in time to chest X-ray for differently timed trauma team activations (P = 0.003. Median time to chest X-ray for teams activated 15–20 minutes prearrival was 5 minutes, and 8 minutes for teams activated <5 minutes before patient arrival. Timing had no effect on length of stay in the emergency department (P = 0.694. We found no effect of preactivation notification on time to chest X-ray (P = 0.474 or length of stay (P = 0.684.Conclusion: Proactive trauma team activation improved the initial management of trauma patients. Trauma teams should be activated prior to patient arrival.Keywords: emergency medical service communication systems

  12. Alpha-2 agonists as pain therapy in horses.

    Science.gov (United States)

    Valverde, Alexander

    2010-12-01

    Alpha-2 agonists, such as xylazine, clonidine, romifidine, detomidine, medetomidine, and dexmedetomidine, are potent analgesic drugs that also induce physiologic and behavioral changes, such as hypertension, bradycardia, atrioventricular block, excessive sedation and ataxia, all of which can potentially limit their systemic use as analgesics in some clinical cases. The use of medetomidine and dexmetomidine has been introduced for equine anesthesia/analgesia, and although not approved in this species, their increased specificity for alpha-2 receptors may offer some potential advantages over the traditional alpha-2 agonists. Similarly, other routes of administration and benefits of alpha-2 agonists are recognized in the human and laboratory animal literature, which may prove useful in the equine patient if validated in the near future. This review presents this relevant information. PMID:21056297

  13. Analysis of agonist dissociation constants as assessed by functional antagonism in guinea pig left atria

    International Nuclear Information System (INIS)

    In electrically driven guinea pig left atria, positive inotropic responses to (-)-isoprenaline and the selective beta 1-adrenoceptor agonist RO363 were obtained in the absence and in the presence of the functional antagonists adenosine, carbachol, gallopamil, nifedipine, and Ro 03-7894. Each of the functional antagonists reduced the maximum response to both agonists and produced nonparallel rightward shifts in the cumulative concentration effect curves. For both agonists, dissociation constants (KA) were calculated using the equation described by Furchgott (1966) for irreversible antagonism. For RO363, which is a partial agonist with high agonist activity, the equations outlined for functional interaction by Mackay (1981) were also employed to calculate KA values. The KA values obtained by each method were compared with the dissociation constants (KD) for the two agonists determined from their ability to displace the radioligand (-)-[125I]iodocyanopindolol from beta 1-adrenoceptors in guinea pig left atrial membrane preparations. The estimates of KA varied substantially from KD values. The KD values were taken as more accurate estimates of the true values for the dissociation constants because a high degree of correlation exists between pKD and pD2 values for a number of other beta-adrenoceptor agonists that behave as partial agonists and between pKD and pKB values for a number of beta-adrenoceptor antagonists. Thus, it appears that there are serious limitations in the current theory for using functional antagonism as a means of obtaining agonist dissociation constants

    Fifty-six subjects complaining of tinnitus underwent an audiometric test and a test for identifying the analogous pitch of their tinnitus. All of the subjects reported that they had been exposed to noise in the past. The subjects were divided into two groups on the basis of their audiometric test results. Group P was composed of subjects who showed a sensorineural hearing loss typical of acoustic trauma. Group N was composed of subjects whose hearing was within normal limits. The pitch of the tinnitus in group P was concentrated in the high-frequency range, whereas in group N tinnitus pitch values were distributed over the low and mid-audiometric frequency spectrum. It was deduced that different processes are involved in the generation of tinnitus in the two groups.

  15. Focused abdominal sonography for trauma (FAST) in blunt paediatric abdominal trauma

    International Nuclear Information System (INIS)

    Objective: To evaluate the role of focussed abdominal sonography for trauma in blunt paediatric abdominal trauma patients, and to see if the role of computed tomography scan could be limited to only those cases in which sonography was positive. Methods: The retrospective study covered 10 years, from January 1, 2000 to December 31, 2009, and was conducted at the Department of Radiology and Department of Emergency Medicine, Aga Khan University Hospital, Karachi. It comprised cases of 174 children from birth to 14 years who had presented with blunt abdominal trauma and had focussed abdominal sonography for trauma done at the hospital. The findings were correlated with computed tomography scan of the abdomen and clinical follow-up. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of focussed abdominal sonography for trauma were calculated for blunt abdominal trauma. SPSS 17 was used for statistical analysis. Results: Of the total 174 cases, 31 (17.81%) were later confirmed by abdominal scan. Of these 31 children, sonography had been positive in 29 (93.54%) children. In 21 (67.74%) of the 31 children, sonography had been true positive; 8 (25%) (8/31) were false positive; and 2 (6%) (2/31) were false negative. There were 6 (19.3%) children in which sonography was positive and converted to laparotomy. There was no significant difference on account of gender (p>0.356). Focussed abdominal sonography for trauma in the study had sensitivity of 91%, specificity of 95%, positive predictive value of 73%, and negative predictive value of 73% with accuracy of 94%. All patients who had negative sonography were discharged later, and had no complication on clinical follow-up. Conclusions: Focussed abdominal sonography for trauma is a fairly reliable mode to assess blunt abdominal trauma in children. It is a useful tool to pick high-grade solid and hollow viscous injury. The results suggest that the role of computed tomography scan can be

    Full Text Available Trauma has assumed epidemic proportion. 10% of global road accident deaths occur in India. Hypoxia and airway mismanagement are known to contribute up to 34% of pre-hospital deaths in these patients. A high degree of suspicion for actual or impending airway obstruction should be assumed in all trauma patients. Objective signs of airway compromise include agitation, obtundation, cyanosis, abnormal breath sound and deviated trachea. If time permits, one should carry out a brief airway assessment prior to undertaking definitive airway management in these patients. Simple techniques for establishing and maintaining airway patency include jaw thrust maneuver and/or use of oro- and nas-opharyngeal airways. All attempts must be made to perform definitive airway management whenever airway is compromised that is not amenable to simple strategies. The selection of airway device and route- oral or -nasal, for tracheal intubation should be based on nature of patient injury, experience and skill level.

    International Nuclear Information System (INIS)

    The maxillofacial skeleton is very vulnerable to injury. The face is a favorite target of blows in assaults or fights and is a primary site of traumatic injury in automobile accidents. Although most injuries can be diagnosed clinically, radiologic imaging is pivotal in the diagnosis and management of these injuries. The accurate diagnosis and complete evaluation of maxillofacial trauma require a comprehensive knowledge of maxillofacial anatomy and an understanding of the mechanisms of maxillofacial injury. The role and efficacy of plain film radiography, thin-section multiplanar tomography, and CT in the diagnosis and management of facial fractures is discussed. CT has proved superior to the other imaging modalities in maxillofacial trauma, especially in complex maxillofacial injuries. The value of CT is stressed and demonstrated

  18. The blunt abdominal trauma

    International Nuclear Information System (INIS)

    Up to 1970 the number of patients suffering from blunt abdominal trauma showed a substantial increase. In more than 50% of all cases there are additional injuries. The most important factor influencing the prognosis of these patients is the early and correct indication for operation and the avoidance of unnecessary laparotomies. As a primary aim in diagnosis one should consider the recognition of an intraperitoneal bleeding without risk for the patient. Peritoneal lavage as an invasive method with low complication rates has proved good. First reports also show good results using the sonography of the abdomen. The recognition of the injured organ allows a carefully directed operation. Concerning the prognosis it is of minor importance. The diagnosis in patients with blunt abdominal trauma at the university clinic of Freiburg consists of: sonography, followed in positive cases by laparotomy or angiography and laparotomy. In cases with questionable results a lavage is done. (orig.)

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

    For the German speaking countries,Tscherne's definition of "polytrauma" which represents an injury of at least two body regions with one or a combination being life-threatening is still valid.The timely and adequate management including quick referral of the trauma patient into a designated trauma center may limit secondary injury and may thus improve outcomes already during the prehospital phase of care.The professional treatment of multiple injured trauma patients begins at the scene in the context of a well structured prehospital emergency medical system.The "Primary Survey" is performed by the emergency physician at the scene according to the Prehospital Trauma Life Support (PHTLS)-concept.The overall aim is to rapidly assess and treat life-threatening conditions even in the absence of patient history and diagnosis ("treat-first-what-kills-first").If no immediate treatment is necessary,a "Secondary Survey" follows with careful and structured body examination and detailed assessment of the trauma mechanism.Massive and life-threatening states of hemorrhage should be addressed immediately even disregarding the ABCDE-scheme.Critical trauma patients should be referred without any delay ("work and go") to TR-DGU(R) certified trauma centers of the local trauma networks.Due to the difficult prehospital environment the number of quality studies in the field is low and,as consequence,the level of evidence for most recommendations is also low.Much information has been obtained from different care systems and the interchangeability of results is limited.The present article provides a synopsis of recommendations for early prehospital care for the severely injured based upon the 2011 updated multidisciplinary S3-Guideline "Polytrauma/Schwerstverletzten Behandlung",the most recently updated European Trauma guideline and the current PHTLS-algorithms including grades of recommendation whenever possible.

    The concept that a bolus of gonadotrophin-releasing hormone agonist (GnRHa) can replace human chorionic gonadotrophin (HCG) as a trigger of final oocyte maturation was introduced several years ago. Recent developments in the area strengthen this premise. GnRHa trigger offers important advantages...... triggering concept should be challenged and that the GnRHa trigger is the way to move forward with thoughtful consideration of the needs, safety and comfort of our patients. Routinely, human chorionic gonadotrophin (HCG) is used to induce ovulation in fertility treatments. This approach deviates...... significantly from physiology and often results in insufficient hormonal support in early pregnancy and in ovarian hyperstimulation syndrome (OHSS). An alternative approach is to use a gonadotrophin-releasing hormone (GnRH) agonist which allows a more physiological trigger of ovulation and, most importantly...

    Full Text Available Abstract The role of Emergency Medicine Physicians (EMP in the care of trauma patients in North America has evolved since the advent of the specialty in the late 1980's. The evolution of this role in the context of the overall demands of the specialty and accreditation requirements of North American trauma centers will be discussed. Limited available data published in the literature examining the role of EMP's in trauma care will be reviewed with respect to its implications for an expanded role for EMPs in trauma care. Two training models currently in the early stages of development have been proposed to address needs for increased manpower in trauma and the critical care of trauma patients. The available information regarding these models will be reviewed along with the implications for improving the care of trauma patients in both Europe and North America.

    The provision of trauma care is a financial burden, continually associated with low reimbursement, and shifts the economic burden to major trauma centers and providers. Meanwhile, the volume of craniomaxillofacial (CMF) trauma and the number of surgically managed facial fractures are unchanged. Past financial analyses of cost and reimbursement for facial trauma are limited to mandibular and midface injuries, consistently revealing low reimbursement. The incurred financial burden also coincides with the changing landscape of health insurance. The goal of this study is to determine the opportunity cost of operative management of facial trauma at our institution. From our CMF database of greater than 3,000 facial fractures, the physician charges, collections, and relative value units (RVUs) for CMF trauma per year from 2007 to 2013 were compared with a general plastic surgery and otolaryngology population undergoing operative management during this same period. Collection rates were analyzed to assess if a significant difference exists between reimbursement for CMF and non-CMF cases. Results revealed a significant difference between the professional collection rate for operative CMF trauma and that for other operative procedures (17.25 vs. 29.61%, respectively; p opportunity cost associated with offering this service is a potential threat to the sustainability of providing care for this population.

  8. Skeletal scintigraphy following incidental trauma

    International Nuclear Information System (INIS)

    The significance of antecedent trauma in skeletal scintigraphy was assessed in 503 patients, of whom 241 (46%) had prior fracture or tooth extraction. In patients with sufficiently accurate histories for site-by-site analysis, 33 of 131 fracture sites and 16 of 83 dental-procedure sites were positive scintigraphically. In general, the frequency of scan positivity diminished as the interval between trauma and scanning increased, but a significant number of patients showed prolonged uptake at fracture sites. Several patterns of uptake suggested trauma rather than metastatic disease. Knowledge of a history of trauma is often critical in bone scan interpretation

    The diagnosis of the traumatized spine is one of the key issues for trauma radiologists. The cross-sectional imaging procedures, computed tomography (CT) and magnetic resonance imaging (MRI) are the essential methods in spinal trauma radiology. These modalities are of great help in accurately assessing injury patterns and extent and in providing indications of patient outcome. In contrast to cross-sectional imaging, radiography has a role in the evaluation of minor spinal trauma only. It is generally accepted that trauma radiologists do not use typical classifications to evaluate the spine partly because such an ideal classification system does not yet exist. Not least because of this classification difficulty, eponyms and synonyms are widely used to describe traumatology of the spine as a high level of specific information is included in these various terms. The members of the trauma team should be aware of the strengths and limitations of the methods used in the assessment of the spine. This article provides a brief outline of fundamental knowledge about the diagnosis of spinal trauma. (orig.)

  13. Digital subtraction angiography in extremity trauma

    International Nuclear Information System (INIS)

    Digital subtraction angiography (DSA) may have considerable impact on the work-up of patients who have suffered trauma. The angiographic evaluation of vascular injuries can be accomplished rapidly and with minimal catheter use and manipulation, which is particularly important for those critically ill patients who have significant immobility because of multiple fractures. The authors retrospectively reviewed the digital subtraction angiograms in 50 consecutive cases of extremity trauma. The quality of the images in 44 of these permitted a confident diagnosis, the accuracy of which was confirmed by surgical or clinical follow-up. DSA reduces the time required to perform the procedure, the amount of contrast material injected, patient discomfort, and film cost. Its major disadvantage is the limited field size of the image intensifier

  14. Management of liver trauma.

    LENUS (Irish Health Repository)

    2012-02-01

    BACKGROUND: Blunt and penetrating liver trauma is common and often presents major diagnostic and management problems. METHODS: A literature review was undertaken to determine the current consensus on investigation and management strategies. RESULTS: The liver is the most frequently injured organ following abdominal trauma. Immediate assessment with ultrasound has replaced diagnostic peritoneal lavage in the resuscitation room, but computerised tomography remains the gold standard investigation. Nonoperative management is preferred in stable patients but laparotomy is indicated in unstable patients. Damage control techniques such as perihepatic packing, hepatotomy plus direct suture, and resectional debridement are recommended. Major complex surgical procedures such as anatomical resection or atriocaval shunting are now thought to be redundant in the emergency setting. Packing is also recommended for the inexperienced surgeon to allow control and stabilisation prior to transfer to a tertiary centre. Interventional radiological techniques are becoming more widely used, particularly in patients who are being managed nonoperatively or have been stabilised by perihepatic packing. CONCLUSIONS: Management of liver injuries has evolved significantly throughout the last two decades. In the absence of other abdominal injuries, operative management can usually be avoided. Patients with more complex injuries or subsequent complications should be transferred to a specialist centre to optimise final outcome.

  15. Spinal trauma. An imaging approach

    International Nuclear Information System (INIS)

    The diagnosis of trauma to the spine - where the slightest oversight may have catastrophic results - requires a thorough grasp of the spectrum of resultant pathology as well as the imaging modalities used in making an accurate diagnosis. In Spinal Trauma, the internationally renowned team of experts provides a comprehensive, cutting-edge exposition of the current vital role of imaging in the diagnosis and treatment of injuries to the axial skeleton. Beginning with a valuable clinical perspective of spinal trauma, the book offers the reader a unique overview of the biomechanics underlying the pathology of cervical trauma. Acute trauma topics include: - Optimization of imaging modalities - Malalignment - signs and significance - Vertebral fractures - detection and implications - Classification of thoraco-lumbar fractures - rationale and relevance - Neurovascular injury. Distilling decades of clinical and teaching expertise, the contributors further discuss the current role of imaging in special focus topics, which include: - The pediatric spine - Sports injuries - The rigid spine - Trauma in the elderly - Vertebral collapse, benign and malignant - Spinal trauma therapy - Vertebral fractures and osteoporosis - Neuropathic spine. All throughout the book, the focus is on understanding the injury, and its implications and complications, through 'an imaging approach'. Lavishly illustrated with hundreds of superb MR images and CT scans, and clear full-color drawings, the authors conclude with a look into the future, defining clinical trends and research directions. Spinal Trauma - with its broad scope, practical imaging approach, and current focus - is designed to enhance confidence and accuracy, making it essential reading for clinicians and radiologists at all levels.

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

    . Conclusion The current study contributes to a very limited literature reporting results from truly prospective examinations of pre-trauma physiologic, psychologic, and demographic predictors of PTSS. Findings that combinations of lower estimated IQ, greater depression symptoms, a larger differential corrugator EMG response during extinction and larger SC responses to loud tones significantly predicted higher PTSS suggests that the process(es underlying these traits contribute to the pathogenesis of subjective and physiological PTSS. Due to the low levels of PTSS severity and relatively restricted ranges of outcome scores due to the healthy nature of the participants, results may underestimate actual predictive relationships.

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

    Science.gov (United States)

    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.

    Paediatric interventional radiology plays a cornerstone role in the management of paediatric trauma. In the acute setting, interventional radiology techniques allow minimally invasive control of haemorrhage or re-establishment of blood flow. Percutaneous stenting and drainage can allow disruptions in urinary or biliary systems to heal without the need for further surgery. Interventional radiology techniques also have a significant role in treating delayed complications of trauma, including embolization of arterial pseudoaneurysms and pulmonary embolism prophylaxis in individuals immobilized due to the trauma or its operative treatment.

They also had leucocytosis (with neutrophylia), hypokalemia and hyperglycaemia. After treatment with potassium i.v. and propranolol, the symptoms disappeared. The symptoms recurred at home because the patients didn't take the prescribed medication and persisted for five days, with spontaneous disappearance. The serum of both patients revealed the presence of clenbuterol (65 hg/ml - father and 58 hg/ml - daughter). The animal's liver had a concentration of 1,42 mg/kg. Clenbuterol is a ß-adrenergic agonist with low specificity, with some veterinary indications. However, this substance has been illegally used as a growth's promotor. We intend to alert doctors for this problem, particularly those that work in the Urgency. PMID:22226216

  13. β2-agonist therapy in lung disease.

    Science.gov (United States)

    Cazzola, Mario; Page, Clive P; Rogliani, Paola; Matera, M Gabriella

    2013-04-01

    β2-Agonists are effective bronchodilators due primarily to their ability to relax airway smooth muscle (ASM). They exert their effects via their binding to the active site of β2-adrenoceptors on ASM, which triggers a signaling cascade that results in a number of events, all of which contribute to relaxation of ASM. There are some differences between β2-agonists. Traditional inhaled short-acting β2-agonists albuterol, fenoterol, and terbutaline provide rapid as-needed symptom relief and short-term prophylactic protection against bronchoconstriction induced by exercise or other stimuli. The twice-daily β2-agonists formoterol and salmeterol represent important advances. Their effective bronchodilating properties and long-term improvement in lung function offer considerable clinical benefits to patients. More recently, a newer β2-agonist (indacaterol) with a longer pharmacodynamic half-life has been discovered, with the hopes of achieving once-daily dosing. In general, β2-agonists have an acceptable safety profile, although there is still controversy as to whether long-acting β2-agonists may increase the risk of asthma mortality. In any case, they can induce adverse effects, such as increased heart rate, palpitations, transient decrease in PaO2, and tremor. Desensitization of β2-adrenoceptors that occurs during the first few days of regular use of β2-agonist treatment may account for the commonly observed resolution of the majority of these adverse events after the first few doses. Nevertheless, it can also induce tolerance to bronchoprotective effects of β2-agonists and has the potential to reduce bronchodilator sensitivity to them. Some novel once-daily β2-agonists (olodaterol, vilanterol, abediterol) are under development, mainly in combination with an inhaled corticosteroid or a long-acting antimuscarinic agent.

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

    We analyzed 26 cases of renal trauma, which occurred during the last 7 years and 6 months. Computed tomography was performed in all cases. Four cases were of type Ib, 13 cases of type II, 3 cases of type IIIa, 5 cases of type IIIb and 1 case of type IVa, according to the classification of renal injury by the Japanese association for the surgery of trauma. Conservative treatment was done in 21 cases, selective transcatheter arterial embolization (TAE) in 4 cases, and surgical treatment in 1 case. Conservative treatment was effective for type I and II renal trauma. In the cases of type IIIa and IIIb renal trauma, open surgery could be avoided and the affected kidney preserved by early TAE.

In a 1-year study all patients > or = 15 years with acute wrist trauma and treated...... in the emergency room were examined according to an algorithm until a diagnosis was established. The overall incidence of wrist trauma was 69 per 10,000 inhabitants per year. Incidence of wrist trauma requiring x-ray examination was 58 per 10,000 per year. The incidence of distal radius fractures was 27 per 10...... using data from a population-based study. A completeness rate of 0.56 (95% confidence interval: 0.31-0.78) was found. An x-ray had been taken for all patients reporting a fracture thus justifying the use of fractures as an incidence measure when comparing groups of patients with wrist trauma....

    Background: Trauma is a major cause of death and disability. Adverse events, such as prolonged prehospital time, hypoxia, hypotension and/or hyperventilation have been reported to correlate to poor outcome. Adequate cortisol levels are essential for survival after major trauma. In hypotensive critically ill patients, lack of sufficient amount of cortisol can be suspected, and a concept of critical illness related corticosteroid insufficiency has been proposed. Corticosteroid therapy has many ...

    Full Text Available PPAR-γ regulates cellular differentiation, development and metabolism. They play these essential roles by functioning as transcription factors regulating the expression of genes. The PPARs mainly are of three types α, β and γ. The PPAR-γ expressed in three forms γ1, γ2 and γ3 present in different tissues. When PPAR binds its ligand, transcription of target gene is increased or decreased. Tzds were able to induce cell differentiation and apoptosis or inhibit cell proliferation both in vitro and in vivo. However, widespread use of thiazolidinediones (TZDs, the clinically used synthetic PPAR gamma agonists, has been limited by adverse effects. So in this review we are suggesting some new molecules other than thiazolidine diones which can act as potential anticancer agents, after explaining the mechanism of action of PPAR-γ agonists as anticancer agents especially thiazolidinediones.

  3. Endovascular interventions for multiple trauma

    International Nuclear Information System (INIS)

    In recent years interventional radiology has significantly changed the management of injured patients with multiple trauma. Currently nearly all vessels can be reached within a reasonably short time with the help of specially preshaped catheters and guide wires to achieve bleeding control of arterial und venous bleeding. Whereas bleeding control formerly required extensive open surgery, current interventional methods allow temporary vessel occlusion (occlusion balloons), permanent embolization and stenting. In injured patients with multiple trauma preinterventional procedural planning is performed with the help of multidetector computed tomography whenever possible. Interventional radiology not only allows minimization of therapeutic trauma but also a considerably shorter treatment time. Interventional bleeding control has developed into a standard method in the management of vascular trauma of the chest and abdomen as well as in vascular injuries of the upper and lower extremities when open surgical access is associated with increased risk. Additionally, pelvic trauma, vascular trauma of the superior thoracic aperture and parenchymal arterial lacerations of organs that can be at least partially preserved are primarily managed by interventional methods. In an interdisciplinary setting interventional radiology provides a safe and efficient means of rapid bleeding control in nearly all vascular territories in addition to open surgical access. (orig.)

  4. Imaging of blunt chest trauma

    International Nuclear Information System (INIS)

    In western European countries most blunt chest traumas are associated with motor vehicle and sport-related accidents. In Switzerland, 39 of 10,000 inhabitants were involved and severely injured in road accidents in 1998. Fifty two percent of them suffered from blunt chest trauma. According to the Swiss Federal Office of Statistics, traumas represented in men the fourth major cause of death (4 %) after cardiovascular disease (38 %), cancer (28 %), and respiratory disease (7 %) in 1998. The outcome of chest trauma patients is determined mainly by the severity of the lesions, the prompt appropriate treatment delivered on the scene of the accident, the time needed to transport the patient to a trauma center, and the immediate recognition of the lesions by a trained emergency team. Other determining factors include age as well as coexisting cardiac, pulmonary, and renal diseases. Our purpose was to review the wide spectrum of pathologies related to blunt chest trauma involving the chest wall, pleura, lungs, trachea and bronchi, aorta, aortic arch vessels, and diaphragm. A particular focus on the diagnostic impact of CT is demonstrated. (orig.)

  6. Radiographic evaluation of hepatic trauma

    International Nuclear Information System (INIS)

    The incidence of significant abdominal trauma continues to rise and accounts currently for approximately 10 percent of the annual 130,000 trauma-related deaths in the United States. Over 60 percent of patients are from 10 to 40 years of age, with a striking predominance of males. Children are mostly victims of blunt trauma, while some large reviews of liver trauma in adults show a prevalence of penetrating injuries. Injury to the liver is second only to the spleen in incidence of intraperitoneal injuries. Morbidity and mortality from hepatic trauma are related to the mechanism and extent of injury. Penetrating injuries generally have a lower mortality, about 5 percent, especially if they are due to stab wounds or low velocity gunshot wounds. Shotgun and high velocity gunshot wounds may cause massive fragmentation of the liver and are associated with proportionately greater mortality. The mortality from blunt trauma is from 15 to 45 percent in many large series. Death from isolated liver injury is uncommon, but is usually due to uncontrolled hemorrhage. Injury to other abdominal organs is associated in many cases, as are injuries to the head, chest, and limbs. The extraabdominal injuries are frequently more apparent clinically, but may mask potentially life-threatening abdominal visceral injuries

    β-Agonists are a group of illegal feed additives. In this paper, it was found that the light emission produced by the oxidation of luminol by potassium ferricyanide was enhanced by the β-agonists (ractopamine, salbutamol, and terbutaline). Based on chemiluminescence phenomenon, a novel, rapid, and sensitive microflow injection analysis system on a microfluidic glass chip was established for determination of the β-agonists. The chip was fabricated from two glass plates (64 mm × 32 mm) with microchannels of 200 μm width and 100 μm depth. The detection limits were achieved at 2.0 × 10(-8) mol/L of ractopamine, 1.0 × 10(-8) mol/L of terbutaline and 5.0 × 10(-7) mol/L of salbutamol. In this report, our method was applied for determination of the β-agonists in swine hair from three different sources with satisfactory results. PMID:25546131

    The aims of this study were to characterize trauma exposure and posttraumatic stress disorder (PTSD) in female drug court participants and test for differences in socioeconomic status and familial status between women with: i) no trauma exposure, ii) trauma exposure without PTSD, and iii) trauma exposure resulting in PTSD. Three hundred nineteen women were recruited from drug courts. Rates of exposure and likelihood of traumatic events leading to PTSD were examined, sociodemographic characteristics were compared across groups, and a logistic regression analysis was conducted to test for differences in PTSD risk for assaultive vs. non-assaultive events. Twenty percent of participants met PTSD criteria, 71% had trauma exposure without PTSD, and 9% did not endorse any traumatic events. Prostitution and homelessness were more prevalent in women with vs. without a history of trauma, but among trauma-exposed women prevalences did not vary by PTSD status. No differences in risk for PTSD were found between assaultive and non-assaultive events (OR=0.91; 95%CI: 0.48–1.75). Women sentenced to drug court represent a heavily trauma-exposed population, for whom risk for PTSD is not limited to assaultive events. Within this high-risk population, trauma is associated with elevated rates of homelessness and prostitution, even in the absence of PTSD. PMID:22789838

    Local immunotherapy resurfaces in the field of cancer as a potential way to cure localized and metastatic disease with limited toxic effects. We have recently demonstrated that local administration of agonistic CD40 antibodies can cure localized as well as disseminated bladder neoplasms. This approach reduces the circulating concentrations of antibodies that would result from systemic delivery, hence resulting in limited toxicity.

    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.

    Assessing a patient with clinical signs of acute spinal cord trauma is an emergency. A radiological work-up is crucial in determining management, and magnetic resonance imaging (MRI) is the modality of choice. It should therefore be performed immediately, preferably within 3 hours, even when plain radiography does not show an abnormality. By choosing an appropriate imaging protocol, it is possible to assess the spinal cord, joints, muscles, ligaments and bone marrow of the spine. Moreover, early MRI findings assist in determining functional prognosis. A major limitation to early MRI is that the examination is usually restricted to stable trauma patients because of the difficulties in monitoring ventilated patients during scanning. However, when an anaesthesiologist with experience in MRI and MR-compatible monitoring equipment is available, even these patients can be safely examined. MRI is also indicated for the evaluation of patients with late complications and sequelae following spinal cord trauma, since many of these chronic lesions are potentially treatable. (orig.)

    Studies on the impact of childhood trauma on postpartum depression show inconsistencies and methodological limitations. The present study examines the effect of childhood trauma on depression 12 and 24 weeks after childbirth, while controlling for history of depression, depression symptoms during pregnancy and type D personality. During the third trimester of pregnancy, 210 women completed self-report questionnaires assessing depression (current and/or past episodes), childhood trauma and type D personality, of whom 187 participated in the postpartum follow-up, with depression symptoms being reassessed at 12 and 24 weeks after delivery with three depression outcome measures. Eventually, 183 participants were retained for analysis. Results indicated no predictive value of childhood trauma on postpartum depression in the univariate analyses, nor after controlling for previous depression, depression symptoms during pregnancy and type D personality. However, past depression and depression symptoms during pregnancy did independently and convincingly predict postpartum depression, especially at 12 weeks and to a lesser extent at 24 weeks following childbirth. Overall, we found no significant association between childhood trauma and postpartum depression. Past depression and depression symptoms during pregnancy are more relevant factors to assess before childbirth. PMID:26189446

  18. Pediatric head trauma: the evidence regarding indications for emergent neuroimaging

    International Nuclear Information System (INIS)

    Traumatic brain injury (TBI) is a leading cause of childhood death and disability worldwide. In the United States, childhood head trauma results in approximately 3,000 deaths, 50,000 hospitalizations, and 650,000 emergency department (ED) visits annually. Children presenting to the ED with seemingly minor head trauma account for approximately one-half of children with documented TBIs. Despite the frequency and importance of childhood minor head trauma, there exists no highly accurate, reliable and validated clinical scoring system or prediction rule for assessing risk of TBI among those with minor head trauma. At the same time, use of CT scanning in these children in recent years has increased substantially. The major benefit of CT scanning is early identification (and treatment) of TBIs that might otherwise be missed and result in increased risk of morbidity and mortality. Unnecessary CT imaging, however, exposes the child needlessly to the risk of radiation-induced malignancies. What constitutes appropriate criteria for obtaining CT scans in children after minor blunt head trauma remains controversial. Current evidence to guide clinicians in this regard is limited; however, large studies performed in multi-center research networks have recently been conducted. These studies should provide the foundation of evidence to guide CT decisions by clinicians, help identify TBIs in a timely fashion, and reduce unnecessary radiation exposure. (orig.)

    2015-10-01

    The dire challenges faced in Haiti, both preearthquake and postearthquake, highlight the need for developing surgical infrastructure to care for traumatic musculoskeletal injuries. The proposed Orthopaedic Trauma Care Specialist (OTCS) residency program aims to close the critical human resource gap that limits the appropriate care of musculoskeletal trauma in Haiti. The OTCS program is a proposal for a 2-year residency program that will focus primarily on the management of orthopaedic trauma. The proposed program will be a comprehensive approach for implementing affordable and sustainable strategies to improve orthopaedic trauma care. Its curriculum will be tailored to the injuries seen in Haiti, and the treatments that can be delivered within their health care system. Its long-term sustainability will be based on a "train-the-trainers" approach for developing local faculty to continue the program. This proposal outlines the OTCS framework specifically for Haiti; however, this concept is likely applicable to other low- and middle-income environments in a similar need for improved trauma and fracture care.

  1. PPAR Agonists and Cardiovascular Disease in Diabetes

    Anna C. Calkin

    2008-01-01

    Full Text Available Peroxisome proliferators activated receptors (PPARs are ligand-activated nuclear transcription factors that play important roles in lipid and glucose homeostasis. To the extent that PPAR agonists improve diabetic dyslipidaemia and insulin resistance, these agents have been considered to reduce cardiovascular risk. However, data from murine models suggests that PPAR agonists also have independent anti-atherosclerotic actions, including the suppression of vascular inflammation, oxidative stress, and activation of the renin angiotensin system. Many of these potentially anti-atherosclerotic effects are thought to be mediated by transrepression of nuclear factor-kB, STAT, and activator protein-1 dependent pathways. In recent clinical trials, PPARα agonists have been shown to be effective in the primary prevention of cardiovascular events, while their cardiovascular benefit in patients with established cardiovascular disease remains equivocal. However, the use of PPARγ agonists, and more recently dual PPARα/γ coagonists, has been associated with an excess in cardiovascular events, possibly reflecting unrecognised fluid retention with potent agonists of the PPARγ receptor. Newer pan agonists, which retain their anti-atherosclerotic activity without weight gain, may provide one solution to this problem. However, the complex biologic effects of the PPARs may mean that only vascular targeted agents or pure transrepressors will realise the goal of preventing atherosclerotic vascular disease.

    Full Text Available Objective: Alcohol addiction too often remains insufficiently treated. It shows the same profile as severe chronic diseases, but no comparable, effective basic treatment has been established up to now. Especially patients with repeated relapses, despite all therapeutic approaches, and patients who are not able to attain an essential abstinence to alcohol, need a basic medication. It seems necessary to acknowledge that parts of them need any agonistic substance, for years, possibly lifelong. For >14 years, we have prescribed such substances with own addictive character for these patients.Methods: We present a documented best possible practice, no designed study. Since 1997, we prescribed Dihydrocodeine (DHC to 102 heavily alcohol addict-ed patients, later, also Buprenorphine, Clomethiazole (>6 weeks, Baclofen and in one case Amphetamine, each on individual indication. This paper focuses on the data with DH, especially. The Clomethiazole-data has been submitted to a German journal. The number of treatments with the other substances is still low. Results: The 102 patients with the DHC-treatment had 1367 medically assisted detoxifications and specialized therapies before! The 4 years-retention rate was 26.4%, including 2.8% successfully terminated treatments. In our 12-step scale on clinical impression, we noticed a significant improvement from mean 3.7 to 8.4 after 2 years. The demand for medically assisted detoxifications in the 2 years remaining patients was reduced by 65.5%. Mean GGT improved from 206.6 U/l at baseline to 66.8 U/l after 2 years. Experiences with the other substances are similar but different in details.Conclusions: Similar to the Italian studies with GHB and Baclofen, we present a new approach, not only with new substances, but also with a new setting and much more trusting attitude. We observe a huge improvement, reaching an almost optimal, stable, long term status in around ¼ of the patients already. Many further

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.

    @@ Acute skin trauma (ie, abrasions, avulsions, blisters, incisions, lacerations, and punctures) is common among individuals involved in work, recreational, and athletic activities. Appropriate management of these wounds is important to promote healing and lessen the risk of cross-contamination and infection. Wound management techniques have undergone significant changes in the past 40 years but many clinicians continue to manage acute skin trauma with long-established, traditional techniques (ie, use of hydrogen peroxide, adhesive strips/patches, sterile gauze, or no dressing) that can delay healing and increase the risk of infection. The purpose of this review is to discuss evidence-based cleansing, debridement, and dressing techniques for the management of acute skin trauma.

    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.

    Liver X receptor (LXR) agonists have been explored as potential treatments for atherosclerosis and other diseases based on their ability to induce reverse cholesterol transport and suppress inflammation. However, this therapeutic potential has been hindered by on-target adverse effects in the liver mediated by excessive lipogenesis. Herein, we report a novel site-specific antibody-drug conjugate (ADC) that selectively delivers a LXR agonist to monocytes/macrophages while sparing hepatocytes. The unnatural amino acid para-acetylphenylalanine (pAcF) was site-specifically incorporated into anti-CD11a IgG, which binds the α-chain component of the lymphocyte function-associated antigen 1 (LFA-1) expressed on nearly all monocytes and macrophages. An aminooxy-modified LXR agonist was conjugated to anti-CD11a IgG through a stable, cathepsin B cleavable oxime linkage to afford a chemically defined ADC. The anti-CD11a IgG-LXR agonist ADC induced LXR activation specifically in human THP-1 monocyte/macrophage cells in vitro (EC50-27 nM), but had no significant effect in hepatocytes, indicating that payload delivery is CD11a-mediated. Moreover, the ADC exhibited higher-fold activation compared to a conventional synthetic LXR agonist T0901317 (Tularik) (3-fold). This novel ADC represents a fundamentally different strategy that uses tissue targeting to overcome the limitations of LXR agonists for potential use in treating atherosclerosis. PMID:25945727

    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.

    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.

    2015-06-01

    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

  13. Trauma care systems in India - An overview

    2004-01-01

    Full Text Available Trauma-care systems in India are at a nascent stage of development. Industrialized cities, rural towns and villages coexist, with variety of health care facilities and almost complete lack of organized trauma care. There is gross disparity between trauma services available in various parts of the country. Rural India has inefficient services for trauma care, due to the varied topography, financial constraints and lack of appropriate health infrastructure. There is no national lead agency to coordinate various components of a trauma system. No mechanism for accreditation of trauma centres and professionals exists. Education in trauma life-support skills has only recently become available. A nationwide survey encompassing various facilities has demonstrated significant deficiencies in current trauma systems. Although injury is a major public-health problem, the government, medical fraternity and the society are yet to recognize it as a growing challenge.

    @@ Introduction Interventional Radiology has evolved into a specialty having enormous input into the care of the traumatized patient. In all hospitals, regardless of size, the Interventional Radiologist must consider their relationships with the trauma service in order to quickly and efficiently render aid to the trauma victim. Such consideration should take place in the light of day as it seems that most trauma occurs in the middle of the night or another inconvenient time. The watchwords of trauma IR are speed and efficiency.

    Paediatric trauma centres seek to optimise the care of injured children. Trends in state-wide paediatric care and outcomes have not been examined in detail in Australia. This study examines temporal trends in paediatric trauma outcomes and factors influencing survival and length of stay. A retrospective review was conducted using data from the NSW Trauma Registry during 2003-2008 for children aged 15 years and younger who were severely injured (injury severity score >15). To examine trauma outcomes descriptive statistics and multivariable logistic and linear regression were conducted. There were 1138 children severely injured. Two-thirds were male. Road trauma and falls were the most common injury mechanisms and over one-third of incidents occurred in the home. Forty-eight percent of violence-related injuries were experienced by infants aged less than 1 year. For the majority of children definitive care was provided at a paediatric trauma centre, but less than one-third of children were taken directly to a paediatric trauma centre post-injury. Children who received definitive treatment at a paediatric trauma centre had between 3 and 6 times higher odds of having a survival advantage than if treated at an adult trauma centre. The number of severe injury presentations to the 14 major trauma centres in NSW remains constant. It is possible that injury prevention measures are having a limited effect on severe injury in NSW. This research provides stimulus for change in the provision and co-ordination in the delivery of trauma care for injured children. PMID:22153117

  4. Trauma imaging in and out of conflict: A review of the evidence

    International Nuclear Information System (INIS)

    Aim: To review the recent evidence that has resulted from experiences in and out of conflict in relation to improving imaging in cases of major trauma. Method: A search of electronic databases, the internet and Cochrane library was undertaken to identify relevant publications which were analysed in terms of quality. Evidence that has emerged from civilian and military practice that could influence the practice of major trauma imaging in future was discussed. Results: The importance of speed in assessing patients suffering major trauma is becoming more recognised. There is growing evidence that the use of portable ultrasound at the site of major trauma as first line investigation has potential. In more stable patients, the evidence for whole body CT at the expense of radiography is also growing. The concern regarding availability and radiation dose related to CT scanning remain significant but with the outcome of the recent Major Trauma Review and improvements in CT scanning techniques, such concerns are being addressed. There is limited research in the use of MRI in relation to major trauma. Conclusion: Ultrasound at the sight of major trauma has potential but further research will be needed. Factors such as operator training in particular need to be considered. CT scanning remains an important diagnostic tool for patients suffering major trauma and this is borne out by the Major Trauma Review and NICE guidelines. The availability of CT scanning in relation to accident and emergency scanning is a factor the Major Trauma Review has highlighted and the close proximity of new CT scanners to accident and emergency is a factor that will need to be taken into account in strategic planning. Given the growing evidence of CT involvement, the continued practice of cervical spine and pelvic radiography in cases of major trauma should be questioned.

    Full Text Available Introduction: The most effective use of trauma center resources helps reduce morbidity and mortality, while saving costs. Identifying critical infrastructure characteristics, patient characteristics and staffing components of a trauma center associated with the proportion of patients needing major trauma care will help planners create better systems for patient care.   Methods: We used the 2009 National Trauma Data Bank-Research Dataset to determine the proportion of critically injured patients requiring the resources of a trauma center within each Level I-IV trauma center (n=443. The outcome variable was defined as the portion of treated patients who were critically injured. We defined the need for critical trauma resources and interventions (“trauma center need” as death prior to hospital discharge, admission to the intensive care unit, or admission to the operating room from the emergency department as a result of acute traumatic injury. Generalized Linear Modeling (GLM was used to determine how hospital infrastructure, staffing Levels, and patient characteristics contributed to trauma center need.     Results: Nonprofit Level I and II trauma centers were significantly associated with higher levels of trauma center need. Trauma centers that had a higher percentage of transferred patients or a lower percentage of insured patients were associated with a higher proportion of trauma center need.  Hospital infrastructure characteristics, such as bed capacity and intensive care unit capacity, were not associated with trauma center need. A GLM for Level III and IV trauma centers showed that the number of trauma surgeons on staff was associated with trauma center need. Conclusion: Because the proportion of trauma center need is predominantly influenced by hospital type, transfer frequency, and insurance status, it is important for administrators to consider patient population characteristics of the catchment area when planning the

  14. Fetal trauma: brain imaging in four neonates

    International Nuclear Information System (INIS)

    The purpose of this paper is to describe brain pathology in neonates after major traffic trauma in utero during the third trimester. Our patient cohort consisted of four neonates born by emergency cesarean section after car accident in the third trimester of pregnancy. The median gestational age (n=4) was 36 weeks (range: 30-38). Immediate post-natal and follow-up brain imaging consisted of cranial ultrasound (n=4), computed tomography (CT) (n=1) and post-mortem magnetic resonance imaging (MRI) (n=1). Pathology findings were correlated with the imaging findings (n=3). Cranial ultrasound demonstrated a huge subarachnoidal hemorrhage (n=1), subdural hematoma (n=1), brain edema with inversion of the diastolic flow (n=1) and severe ischemic changes (n=1). In one case, CT demonstrated the presence and extension of the subarachnoidal hemorrhage, a parietal fracture and a limited intraventricular hemorrhage. Cerebellar hemorrhage and a small cerebral frontal contusion were seen on post-mortem MRI in a child with a major subarachnoidal hemorrhage on ultrasound. None of these four children survived (three children died within 2 days and one child died after 1 month). Blunt abdominal trauma during pregnancy can cause fetal cranial injury. In our cases, skull fracture, intracranial hemorrhage and hypoxic-ischemic encephalopathy were encountered. (orig.)

    Prenatal maternal mood may inform the adverse obstetric outcomes seen in disadvantaged populations. The contribution of having a trauma history is not well studied. We examined the impact of trauma exposure and mood symptoms on obstetric outcomes in 358 women. Women with antecedent trauma were more likely to have a history of depression, odds ratio = 2.83, 95% confidence interval [1.81, 4.42], were younger at their first pregnancy, 18.86 years versus 20.10 years, and had a higher number of previous pregnancies, 2.01 versus 1.54, compared to those with no trauma exposure. Women with prenatal anxiety had significantly smaller babies than nonanxious women, 3,313.17 g, (SD = 441.58) versus 3,429.27 g, (SD = 437.82) Trauma history magnified the effects of maternal prenatal mood on birthweight; the moderating effect was limited to those who first experienced a trauma under 18 years of age. Childhood trauma exposure increased vulnerability for low birthweight delivery associated with prenatal mood disturbance. Screening pregnant women for trauma history and current mood symptoms is indicated. PMID:27276162

    2016-08-01

    The Great East Japan Earthquake (GEJE) struck the northeastern part of Japan on 11 March 2011 and triggered a devastating tsunami, causing widespread destruction along the coast of northeastern Japan. The tsunami also led to an accident at the Fukushima Daiichi nuclear power plant. Incidents occurring in such major disasters are known to lead to psychological trauma. This paper has summarized English-language documentation regarding GEJE-related psychological trauma or post-traumatic stress disorder (PTSD). Research thus far has reported the possibility of higher probable PTSD prevalence among residents of the GEJE areas than in the average Japanese population during normal times. At the very least, many people have experienced trauma symptoms at self-recognition levels 1 year or longer after the disaster. It appears that the percentage of persons with high PTSD risk was higher in regions with radiation-related impacts than in regions where the main damage was caused by the earthquake and tsunami. Results have not been limited to showing relations between severe exposure to a traumatic event and PTSD symptoms but also show that a variety of factors, including social factors, has been shown to interact with PTSD symptoms. The fact that Japanese society as a whole united against the trauma of the GEJE may have worked to minimize the effects of trauma. To grasp a full picture of the effects of psychological trauma due to the GEJE, further surveys and research are necessary. It will be necessary to continue engagements related to these problems and issues into the future. PMID:27192947

    2016-05-01

    An essential but often overlooked component to promoting trauma-informed care within the child welfare system is educating and empowering foster, adoptive, and kinship caregivers (resource parents) with a trauma-informed perspective to use in their parenting as well as when advocating for services for their child. In this first evaluation of the National Child Traumatic Stress Network's trauma-informed parenting workshop (Caring for Children who Have Experienced Trauma, also known as the Resource Parent Curriculum), participant acceptance and satisfaction and changes in caregiver knowledge and beliefs related to trauma-informed parenting were examined. Data from 159 ethnically diverse resource parents were collected before and after they participated in the workshop. Results demonstrate that kinship and nonkinship caregivers showed significant increases in their knowledge of trauma-informed parenting and their perceived self-efficacy parenting a child who experienced trauma. Nonkinship caregivers increased on their willingness to tolerate difficult child behaviors, whereas kinship caregivers did not show a significant change. Participants also demonstrated high levels of satisfaction with the workshop. Although these preliminary results are important as the first empirical study supporting the workshop's effectiveness, the limitations of this study and the directions for future research are discussed.

    Hoover, Stephanie M; Luchner, Andrew F; Pickett, Rachel F

    2016-01-01

    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

  20. beta2-Agonists at the Olympic Games.

    2006-01-01

    The different approaches that the International Olympic Committee (IOC) had adopted to beta2-agonists and the implications for athletes are reviewed by a former Olympic team physician who later became a member of the Medical Commission of the IOC (IOC-MC). Steadily increasing knowledge of the effects of inhaled beta2-agonists on health, is concerned with the fact that oral beta2-agonists may be anabolic, and rapid increased use of inhaled beta2-agonists by elite athletes has contributed to the changes to the IOC rules. Since 2001, the necessity for athletes to meet IOC criteria (i.e., that they have asthma and/or exercise-induced asthma [EIA]) has resulted in improved management of athletes. The prevalence of beta2-agonist use by athletes mirrors the known prevalence of asthma symptoms in each country, although athletes in endurance events have the highest prevalence. The age-of-onset of asthma/EIA in elite winter athletes may be atypical. Of the 193 athletes at the 2006 Winter Olympics who met th IOC's criteria, only 32.1% had childhood asthma and 48.7% of athletes reported onset at age 20 yr or older. These findings lead to speculation that years of intense endurance training may be a causative factor in bronchial hyperreactivity. The distinction between oral (prohibited in sports) and inhaled salbutamol is possible, but athletes must be warned that excessive use of inhaled salbutamol can lead to urinary concentrations similar to those observed after oral administration. This article provides justification that athletes should provide evidence of asthma or EIA before being permitted to use inhaled beta2-agonists. PMID:17085798

  1. The role of interventional radiology in trauma

    International Nuclear Information System (INIS)

    This is a lecture on the role of interventional radiology in trauma. Trauma is classified into either blunt with a wide distribution of force to the patient or penetrating which has a narrower and knifing type of presentation. Penetrating trauma requires the tissues injured be fully examined by both cross-sectional imaging and, if hemorrhage is occurring, by arteriography where as blunt trauma is not so localized and requires the examination of much wider area of the body. Embolization of any bleeding site should occur at the time of diagnosis. embolization should be accomplished using either gelfoam or stainless or platinum coils. The treatments of pelvic trauma, renal trauma and ceres bral trauma are introduced in detail in this lecture

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

    Infants with neonatal abstinence syndrome and their mothers require extended support through health and social service systems. Practitioners are interested in exploring innovative approaches to caring for infants and mothers. There is now compelling evidence linking women's substance use to experiences of trauma and violence. A significant shift in the fields of addiction and mental health has been awareness of the impact of trauma and violence on infants and children, women, their families, and communities. In this article, the current state of knowledge of trauma-informed care is reviewed, in particular for application to practice within the NICU. Trauma survivors are at risk of being retraumatized because of health care providers' limited understanding of how to work effectively with them. Recognizing the impact of trauma and implementing evidence-based trauma-informed practices in the NICU holds promise for improving outcomes for women and their infants. PMID:25391589

    Recent federal legislation and a renewed focus on integrative care models underscore the need for economical, effective, and science-based behavioral health care treatment. As such, maximizing the impact and reach of treatment research is of great concern. Behavioral health issues, including the frequent co-occurrence of substance use disorders (SUD) and posttraumatic stress disorder (PTSD), are often complex, with a myriad of factors contributing to the success of interventions. Although treatment guides for comorbid SUD/PTSD exist, most patients continue to suffer symptoms following the prescribed treatment course. Further, the study of efficacious treatments has been hampered by methodological challenges (e.g., overreliance on "superiority" designs (i.e., designs structured to test whether or not one treatment statistically surpasses another in terms of effect sizes) and short term interventions). Secondary analyses of randomized controlled clinical trials offer potential benefits to enhance understanding of findings and increase the personalization of treatment. This paper offers a description of the limits of randomized controlled trials as related to SUD/PTSD populations, highlights the benefits and potential pitfalls of secondary analytic techniques, and uses a case example of one of the largest effectiveness trials of behavioral treatment for co-occurring SUD/PTSD conducted within the National Drug Abuse Treatment Clinical Trials Network (NIDA CTN) and producing 19 publications. The paper concludes with implications of this secondary analytic approach to improve addiction researchers' ability to identify best practices for community-based treatment of these disorders. Innovative methods are needed to maximize the benefits of clinical studies and better support SUD/PTSD treatment options for both specialty and non-specialty healthcare settings. Moving forward, planning for and description of secondary analyses in randomized trials should be given equal

    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

    Airway remodeling is a hallmark feature of asthma and chronic obstructive pulmonary disease. Clinical studies and animal models have demonstrated increased airway smooth muscle (ASM) mass, and ASM thickness is correlated with severity of the disease. Current medications control inflammation and reverse airway obstruction effectively but have limited effect on remodeling. Recently we identified the expression of bitter taste receptors (TAS2R) on ASM cells, and activation with known TAS2R agonists resulted in ASM relaxation and bronchodilation. These studies suggest that TAS2R can be used as new therapeutic targets in the treatment of obstructive lung diseases. To further establish their effectiveness, in this study we aimed to determine the effects of TAS2R agonists on ASM growth and promitogenic signaling. Pretreatment of healthy and asthmatic human ASM cells with TAS2R agonists resulted in a dose-dependent inhibition of ASM proliferation. The antimitogenic effect of TAS2R ligands was not dependent on activation of protein kinase A, protein kinase C, or high/intermediate-conductance calcium-activated K(+) channels. Immunoblot analyses revealed that TAS2R agonists inhibit growth factor-activated protein kinase B phosphorylation without affecting the availability of phosphatidylinositol 3,4,5-trisphosphate, suggesting TAS2R agonists block signaling downstream of phosphatidylinositol 3-kinase. Furthermore, the antimitogenic effect of TAS2R agonists involved inhibition of induced transcription factors (activator protein-1, signal transducer and activator of transcription-3, E2 factor, nuclear factor of activated T cells) and inhibition of expression of multiple cell cycle regulatory genes, suggesting a direct inhibition of cell cycle progression. Collectively, these findings establish the antimitogenic effect of TAS2R agonists and identify a novel class of receptors and signaling pathways that can be targeted to reduce or prevent airway remodeling as well as

    1983-05-01

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

  14. Sonography of blunt abdominal trauma

    International Nuclear Information System (INIS)

    Sonographic examination of the abdomen after blunt abdominal trauma represents a rapid and effective diagnostic method without bothering the patient. It has proved its value not only in the confirmation or exclusion of free fluid in the abdomen caused by liver of spleen rupture, but also in such cases actually it replaces peritoneal lavage or exploratory laparotomy. It is also qualified for diagnosis of intraparenchymal or subcapsular hemorrhages, intraperitoneal as well as retroperitoneal and for follow up. In particualr delayed bleedings including the risk of a retarded organ rupture can be detected early. A failure rate of 1.4% in 282 sonographically examined cases of blunt abdominal trauma further confirms the reliability of this method. (orig.)

    Full Text Available Bipolar disorder is a chronic disorder in which irregular course of depressive, mania or mixed episodes or a complete recovery between episodes can be observed. The studies about the effects of traumatic events on bipolar disorder showed that they had significant and long-term effects on the symptoms of the disorder. Psychosocial stress might change the neurobiology of bipolar disorder over time. The studies revealed that the traumatic events could influence not only the onset of the disorder but also the course of the disorder and in these patients the rate of suicide attempt and comorbid substance abuse might increase. Bipolar patients who had childhood trauma had an earlier onset, higher number of episodes and comorbid disorders. In this review, the relationship between childhood trauma and bipolar disorder is reviewed. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2015; 7(2: 157-165

    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.

    In the management of renal trauma, surgical exploration inevitably leads to nephrectomy in all but a few specialized centers. With current management options, the majority of hemodynamically stable patients with renal injuries can be successfully managed nonoperatively.

    In a report describing life ending fractures (255 horses) from the Livestock Disease Diagnostic Center, Kentucky (1993 and 1994), 32 foals had rib fractures. The purpose of our study was to examine the incidence of rib fractures in newborn foals on a Thoroughbred studfarm by physical and radiographic examination, to determine factors which may contribute to the problem and to document any clinical consequences. All foals (263) included were examined within 3 days of birth. The thoracic cage was palpated externally for abnormalities and all foals were placed in dorsal recumbency to evaluate thoracic cage symmetry. Radiographs were used to diagnose foals with thoraciccage asymmetry (TCA) and rib fracture (RF). A diagnosis of costochondral dislocation (CD) was made when no radiographic evidence of fracture was present but there was severe TCA, Fifty-five foals (20.1%) had TCA (9 RF), One to 5 ribs were fractured on 9 of 40 radiographic studies. No consequences of the thoracic trauma was detected clinically, radiographically or ultrasonographically in this group of foals or at a 2- and 4-week follow-up examination. The percentage of foals with a history of abnormal parturition was higher in the TCA foals (15%) compared to the normal foals (6.8%). There weremore primiparous dams in the TCA group than in the normal foal group. Fillies (56.6%) had a higher incidence of birth trauma than colts (43.4%), Thisstudy demonstrates that thoracic trauma is often present in newborn foals and may not always be of clinical significance. Dystocia foals and foals from primiparous mares should be considered high risk for thoracic trauma

  7. Establishment of a course for Focused Assessment Sonography for Trauma

    International Nuclear Information System (INIS)

    Focused Assessment Sonography for Trauma (FAST) is not widely practiced by Trauma Surgeons in the Middle East despite its international acceptance. A FAST course was established by the Trauma Group at the Faculty of Medicine and Health Sciences at United Arab Emirates (UAE) University aiming to introduce doctors who have limited experience of ultrasound to the basics of FAST. This article summarizes the content of the course; the evaluation of the participants and their recommendations. An 8 hour FAST course was offered to 18 participants in May 2004 in the Faculty of Medicine and Health Sciences, UAE University, Al-Ain, UAE. Lectures with syllabus material were used to cover the following topics: basic ultrasound physics, knobology and sonographic orientation, the FAST scan, chest and cardiac trauma sonographic evaluation, training and credentialing issues. Each participant received 3 hours of hands-on ultrasound instruction. On completion of the course participants responded anonymously to an evaluation questionnaire. All participants responded to the questionnaire (100% response rate). Delegates found the course well organized, relevant, met their needs and encourages them to use FAST in their own practice. The course objectives were met. Participants suggested that including actual patients and the use of animal models improve the practical sessions. Organizing a FAST course is an important step towards recognizing and implementing it in practice. Nevertheless, there is a need for appropriate quality assurance and credentialing guidelines before commencing. (author)

    Full Text Available GSK5182 (4 is currently one of the lead compounds for the development of estrogen-related receptor gamma (ERRγ inverse agonists. Here, we report the design, synthesis, pharmacological and in vitro absorption, distribution, metabolism, excretion, toxicity (ADMET properties of a series of compounds related to 4. Starting from 4, a series of analogs were structurally modified and their ERRγ inverse agonist activity was measured. A key pharmacophore feature of this novel class of ligands is the introduction of a heterocyclic group for A-ring substitution in the core scaffold. Among the tested compounds, several of them are potent ERRγ inverse agonists as determined by binding and functional assays. The most promising compound, 15g, had excellent binding selectivity over related subtypes (IC50 = 0.44, >10, >10, and 10 μM at the ERRγ, ERRα, ERRβ, and ERα subtypes, respectively. Compound 15g also resulted in 95% transcriptional repression at a concentration of 10 μM, while still maintaining an acceptable in vitro ADMET profile. This novel class of ERRγ inverse agonists shows promise in the development of drugs targeting ERRγ-related diseases.

  9. Reciprocity of agonistic support in ravens.

    Cooperative behaviour through reciprocation or interchange of valuable services in primates has received considerable attention, especially regarding the timeframe of reciprocation and its ensuing cognitive implications. Much less, however, is known about reciprocity in other animals, particularly birds. We investigated patterns of agonistic support (defined as a third party intervening in an ongoing conflict to attack one of the conflict participants, thus supporting the other) in a group of 13 captive ravens, Corvus corax. We found support for long-term, but not short-term, reciprocation of agonistic support. Ravens were more likely to support individuals who preened them, kin and dominant group members. These results suggest that ravens do not reciprocate on a calculated tit-for-tat basis, but aid individuals from whom reciprocated support would be most useful and those with whom they share a good relationship. Additionally, dyadic levels of agonistic support and consolation (postconflict affiliation from a bystander to the victim) correlated strongly with each other, but we found no evidence to suggest that receiving agonistic support influences the victim's likelihood of receiving support (consolation) after the conflict ends. Our findings are consistent with an emotionally mediated form of reciprocity in ravens and provide additional support for convergent cognitive evolution in birds and mammals. PMID:22298910

    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.

    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.

    1993-01-01

    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

    Since early 2014, Ukraine has been involved in a violent social and political revolution that has taken more than 7,000 lives. Many of these deaths were due to limited field medical care and prolonged evacuation times because the Ukrainian military has been slow to adopt standard combat medical processes. We deployed with the US Army's 173rd Airborne Brigade to train soldiers in the National Guard of Ukraine (NGU) on combat first aid. We discovered that a major deficiency limiting the quality of trauma care and evacuation is an endemic lack of prior coordination and planning. The responsibility for this coordination falls on military leaders; therefore, we delivered medical operations training to officers of the NGU unit and observed great improvement in medical care sustainment. We recommend systematic leader education in best medical practices be institutionalized at all levels of the Ukrainian Army to foster sustained improvement and refinement of trauma care.

    2006-02-01

    Nineteen empirical studies providing evidence about the nature of trauma narratives in posttraumatic stress disorder (PTSD) were reviewed. Selected studies had participants with a diagnosis of PTSD or with PTSD symptoms. The studies used either linguistic indices or participants' rating of narrative quality. There was evidence of a relationship between PTSD specific pathology and the occurrence of sensory/perceptual references and disturbed temporal aspects. Evidence for PTSD-related narrative fragmentation was inconclusive, and there were little data about specific self-referential content. Poor validity and confusion of content and syntactic aspects of narrative organization limited the data on the organization of PTSD narratives. Approaches that address some of these limitations and allow narrative-based evaluation of memory for trauma in PTSD are outlined. PMID:16568467

    Full Text Available Inverse agonists are useful active ingredient of drugs clinically used to treat diseases mainly involving receptors endowed with non-endogenous agonist induced activity (constitutive or basal activity. SP-1e and SP-1g are the first two potent and highly selective β3-adrenoceptor inverse agonists [EC50=181 nM (IA=- 64% and 136 nM (IA=-73%, respectively], which their peculiar activity seems due to the absolute configurations of the two stereogenic centres present in each molecule. Rat proximal colon motility measurements allowed their further pharmacological characterization and pA2 values determination by Schild analysis (7.89 and 8.16, respectively. The purpose of our work is a further characterization of our novel β3-adrenoceptor agonists (SP-1a-d, SP-1f,1h and inverse agonists (SP-1e and SP-1g on rat proximal colon motility and a confirmation of their inverse agonist nature in a more complex system like the functional test on rat proximal colon. Male Wistar rats segment of the proximal colon were placed in organ baths containing Krebs solution. Muscle tension was recorded isotonically. Cumulative β3-AR agonists doses experiments were performed for each test compound: isoprenaline, BRL37344, SP-1a-d, SP-1f and SP-1h were dissolved in Krebs. The EC50 values of each agonists and pA2 of inverse agonists were determined. SP- 1a-d, SP-1f and SP-1h in rat colon have a muscle relaxing effect thus confirming their partial agonist activity found in CHO-K1 cell line. SP-1e and SP-1g behaved as antagonists with pA2 values of 7.89 and 8.16, respectively. In conclusion, experiments carried out by using isolated rat proximal colon allowed us to determine the pA2 values of the two β3-AR inverse agonists and add knowledge on the behavior of a novel set of compounds and their possible value as agents useful whenever is necessary to also control the colon motility.

    Glucagon-like peptide-1(GLP-1)receptor agonists result in greater improvements in glycemic control than placebo and promote weight loss with minimal hypoglycemia in patients with type 2 diabetes mellitus.A number of case reports show an association of GLP-1receptor agonists,mainly exenatide,with the development of acute kidney injury.The present review aims to present the available data regarding the effects of GLP-1 receptor agonists on renal function,their use in subjects with chronic renal failure and their possible association with acute kidney injury.Based on the current evidence,exenatide is eliminated by renal mechanisms and should not be given in patients with severe renal impairment or end stage renal disease.Liraglutide is not eliminated by renal or hepatic mechanisms,but it should be used with caution since there are only limited data in patients with renal or hepatic impairment.There is evidence from animal studies that GLP-1 receptor agonists exert protective role in diabetic nephropathy with mechanisms that seem to be independent of their glucose-lowering effect.Additionally,there is evidence that GLP-1 receptor agonists influence water and electrolyte balance.These effects may represent new ways to improve or even prevent diabetic nephropathy.

    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

    Full Text Available Abstract Background While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL in HIV. Methods The present study focused on HIV in the context of childhood trauma and its impact on functionality and Quality of Life (QoL by evaluating 85 HIV-positive (48 with childhood trauma and 37 without and 52 HIV-negative (21 with childhood trauma and 31 without South African women infected with Clade C HIV. QoL was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q, the Patient's Assessment of Own Functioning Inventory (PAOFI, the Activities of Daily Living (ADL scale and the Sheehan Disability Scale (SDS. Furthermore, participants were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D and the Childhood Trauma Questionnaire (CTQ. Results Subjects had a mean age of 30.1 years. After controlling for age, level of education and CES-D scores, analysis of covariance (ANCOVA demonstrated significant individual effects of HIV status and childhood trauma on self-reported QoL. No significant interactional effects were evident. Functional limitation was, however, negatively correlated with CD4 lymphocyte count. Conclusions In assessing QoL in HIV-infected women, we were able to demonstrate the impact of childhood trauma on functional limitations in HIV.

  5. The potential and the pitfalls of beta-adrenoceptor agonists for the management of skeletal muscle wasting.

    Ryall, James G; Lynch, Gordon S

    2008-12-01

    The beta-adrenergic signaling pathway represents a novel therapeutic target for skeletal muscle wasting and weakness due to its role in the mechanisms controlling protein synthesis and degradation and in modulating fiber type. Stimulation of the pathway with beta-adrenoceptor agonists (beta-agonists) has therapeutic potential for muscle wasting disorders including: sarcopenia, cancer cachexia, disuse and inactivity, unloading or microgravity, sepsis and other metabolic disorders, denervation, burns, HIV-AIDS, chronic kidney or heart failure, and neuromuscular diseases. However, there are also pitfalls associated with beta-agonist administration and clinical applications have so far been limited, largely because of cardiovascular side effects. In rats and mice, newer generation beta-agonists (such as formoterol) can elicit an anabolic response in skeletal muscle even at very low doses, with reduced effects on the heart and cardiovascular system compared with older generation beta-agonists (such as fenoterol and clenbuterol). However, the potentially deleterious cardiovascular side effects of beta-agonists have not been obviated completely and so it is important to refine their development and therapeutic approach in order to overcome these obstacles. This review describes the therapeutic potential of stimulating the beta-adrenergic signaling pathway with beta-agonists, highlighting the beneficial effects on skeletal muscle structure and function and identifying some of the pitfalls associated with short- and long-term beta-agonist administration. The review also identifies some important, but as yet unanswered questions, regarding the importance of beta-adrenoceptor signaling in muscle health and disease and the strategies needed to improve the efficacy and safety of beta-agonists for muscle wasting disorders.

    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

    Full Text Available Aim: Prevention of secondary injury developing as a result of spinal cord injury will reduce significantly neurological deficits which may occur after trauma. These are focused in experimental studies and many agents are being tested. In our study, we have invesitigated the effects of kefir, which is a a probiotic, associated with life prolongation, whose antioxidant and lipid peroxidation effects were revealed on despite the scientific studies were limited, on lipid peroxidation and lysosomal proteases which play important roles in spinal cord. Material and Method: In the study, female Sprague Dawley rats weighing 200 to 250 g were used. The study was conducted on five groups with a total of 40 rats including the control, trauma, trauma treatment, trauma treatment kefir and trauma kefir groups. The high-dose methylprednisolone was used as the therapy. Spinal cord trauma was performed with clip compression method at the level of T10. Kefir was given to rats via orogastric ways, prior to trauma for 7 days at a dose of 2 * 1cc/100g. All rats were sacrificed 48 hours after treatment. The changes in the value of tissue cathepsins B and L, MDA and histopathological changes were examined. Results: It has been found in our study according to the review of biochemical values that; kefir did not reduce significantly cathepsin B values compared to the treatment group (p> 0.05, did reduce significantly MDA value compared to treatment group (p

    2010-01-01

    For centuries Cannabis sativa and cannabis extracts have been used in natural medicine. Delta(9)-tetrahydrocannabinol (THC) is the main active ingredient of Cannabis. THC seems to be responsible for most of the pharmacological and therapeutic actions of cannabis. In a few countries THC extracts (i.e. Sativex) or THC derivatives such as nabilone, and dronabinol are used in the clinic for the treatment of several pathological conditions like chemotherapy-induced nausea and vomiting, multiple sclerosis and glaucoma. On the other hand the severe side effects and the high abuse liability of these agents represent a serious limitation in their medical use. In addition, diversion in the use of these active ingredients for recreational purpose is a concern. Over recent years, alternative approaches using synthetic cannabinoid receptor agonists or agents acting as activators of the endocannabinoid systems are under scrutiny with the hope to develop more effective and safer clinical applications. Likely, in the near future few of these new molecules will be available for clinical use. The present article review recent study and patents with focus on the cannabinoid system as a target for the treatment of central nervous system disorders with emphasis on agonists. PMID:19832688

    In addition to hypopigmentation of the skin and red iris colouration, albino animals also display distinct physiological and behavioural alterations. However, information on the social interactions of albino animals is rare and has mostly been limited to specially bred strains of albino rodents and animals from unique environments in caves. Differentiating between the effects of albinism and domestication on behaviour in rodents can be difficult, and social behaviour in cave fish changes according to species-specific adaptations to conditions of permanent darkness. The agonistic behaviours of albino offspring of pigmented parents have yet to be described. In this study, we observed agonistic behaviour in albino and pigmented juvenile Silurus glanis catfish. We found that the total number of aggressive interactions was lower in albinos than in pigmented catfish. The distance between conspecifics was also analysed, and albinos showed a tendency towards greater separation from their same-coloured conspecifics compared with pigmented catfish. These results demonstrate that albinism can be associated with lower aggressiveness and with reduced shoaling behaviour preference, as demonstrated by a tendency towards greater separation of albinos from conspecifics.

    The ligand activated transcription factor farnesoid X receptor (FXR) is a crucial regulator of several metabolic and inflammatory pathways and its activation by agonistic ligands seems a valuable therapeutic approach for many disorders. Most known non-steroidal FXR agonists however, have limitations that hinder their clinical development and novel FXR ligands are required. Evaluation of the co-crystal structures of the widely used FXR agonist GW4064 and related compounds in complex with the FXR ligand binding domain indicated that their disubstituted isoxazole moiety is especially relevant for FXR activation. By investigation of GW4064-fragments missing the aromatic tail, we discovered a highly potent and soluble partial FXR agonist (14, ST-1892) as well as a fluorescent FXR ligand (15) as potential pharmacological tool.

    Introduction: The most effective use of trauma center resources helps reduce morbidity and mortality, while saving costs. Identifying critical infrastructure characteristics, patient characteristics and staffing components of a trauma center associated with the proportion of patients needing major trauma care will help planners create better systems for patient care. Methods: We used the 2009 National Trauma Data Bank-Research Dataset to determine the proportion of criti...

  4. Selective adenosine A2A receptor agonists and antagonists protect against spinal cord injury through peripheral and central effects

    Full Text Available Abstract Background Permanent functional deficits following spinal cord injury (SCI arise both from mechanical injury and from secondary tissue reactions involving inflammation. Enhanced release of adenosine and glutamate soon after SCI represents a component in the sequelae that may be responsible for resulting functional deficits. The role of adenosine A2A receptor in central ischemia/trauma is still to be elucidated. In our previous studies we have demonstrated that the adenosine A2A receptor-selective agonist CGS21680, systemically administered after SCI, protects from tissue damage, locomotor dysfunction and different inflammatory readouts. In this work we studied the effect of the adenosine A2A receptor antagonist SCH58261, systemically administered after SCI, on the same parameters. We investigated the hypothesis that the main action mechanism of agonists and antagonists is at peripheral or central sites. Methods Spinal trauma was induced by extradural compression of SC exposed via a four-level T5-T8 laminectomy in mouse. Three drug-dosing protocols were utilized: a short-term systemic administration by intraperitoneal injection, a chronic administration via osmotic minipump, and direct injection into the spinal cord. Results SCH58261, systemically administered (0.01 mg/kg intraperitoneal. 1, 6 and 10 hours after SCI, reduced demyelination and levels of TNF-α, Fas-L, PAR, Bax expression and activation of JNK mitogen-activated protein kinase (MAPK 24 hours after SCI. Chronic SCH58261 administration, by mini-osmotic pump delivery for 10 days, improved the neurological deficit up to 10 days after SCI. Adenosine A2A receptors are physiologically expressed in the spinal cord by astrocytes, microglia and oligodendrocytes. Soon after SCI (24 hours, these receptors showed enhanced expression in neurons. Both the A2A agonist and antagonist, administered intraperitoneally, reduced expression of the A2A receptor, ruling out the possibility that the

    Blunt chest trauma is associated with high morbidity and mortality. Consequently, all patients should be evaluated radiologically after blunt chest trauma to allow timely and appropriate treatment. Conventional chest radiographs and computed tomography (CT) are proven modalities with which to evaluate patients after blunt chest trauma. Over the last several years extended focused assessment with sonography for trauma (eFAST) has gained increasing importance for the initial assessment of seriously injured patients. In the acute phase of severely injured patients eFAST examinations are helpful to exclude pneumothorax, hemothorax and hemopericardium. Chest radiographs may also be used to diagnose a pneumothorax or hemothorax; however, the sensitivity is limited and CT is the diagnostic modality of choice to evaluate severely injured patients. (orig.) [German] Stumpfe Thoraxtraumen gehen mit einer hohen Morbiditaet und Mortalitaet einher. Daher sollten Patienten mit Verdacht auf ein stumpfes Thoraxtrauma rasch radiologisch untersucht werden, damit die entsprechenden therapeutischen Schritte zeitgerecht eingeleitet werden koennen. Zur Abklaerung von Patienten nach einem stumpfen Thoraxtrauma sind seit Jahren das konventionelle Lungenroentgen und die Computertomographie bewaehrte Verfahren. In den letzten Jahren hat die fokussierte Ultraschalluntersuchung (eFAST, Extended Focused Assessment with Sonography for Trauma) von schwerverletzten Patienten vermehrt an Bedeutung gewonnen. Durch eine eFAST-Untersuchung kann in der Akutphase rasch geklaert werden, ob bei dem Patienten ein therapiebeduerftiger Pneumothorax, Haematoperikard oder Haematothorax vorliegen. Auch das Lungenroentgen wird zur Diagnose eines Pneumothorax oder Haematothorax eingesetzt, wenngleich seine Sensitivitaet deutlich eingeschraenkt ist. Die CT ist das diagnostische Verfahren der Wahl, um v. a. Patienten mit einem schweren Thoraxtrauma abzuklaeren. (orig.)

    Full Text Available Background and Objectives: The relationship between trauma, post-traumatic stress disorder (PTSD, and psychosis has promoted heterogeneous research lines, in both etiopathogenic and nosological areas. The main aim of this review is to provide a systematic framework that encompasses this theoretical gap in the literature. Methods: A literature research was carried out through PubMed and PsycINFO between 1980 and May 2013. One hundred and thirteen articles were recruited. A first part of this review describes the role of trauma in the development of psychosis. The second part focuses on research about PTSD and psychosis. Results: Longitudinal and cross-sectional studies with clinical and community samples confirm that childhood trauma (CT is a vulnerability factor for schizophrenia and psychotic-like symptoms in adulthood. More empirical research is needed in order to assess the role of trauma as precipitant of acute psychosis. There is also preliminary evidence with cross-sectional samples that suggests that PTSD and psychosis are a risk factor for each other, with studies about post-psychotic PTSD (PP-PTSD being outstanding. Finally, results from different comparative research studies postulate a subtype of PTSD with psychotic features (PTSD-SP. Conclusions: The role of trauma in psychosis is more conclusive as predispositional rather than as trigger factor. Nosological status of acute psychoses remains a focus of controversy unresolved. The association between PTSD and psychosis is complex, requiring more prospective research in order to determine causal relationships between these pathologies. Also, research in nosological status of PTSD-SP must encourage more comparative studies not limited to neurobiological variables.

    Full Text Available Restoration of the quality of life (QoL of trauma injury survivors is the aim of trauma rehabilitation. It is generally acknowledged that sexuality is an important component of QoL; however, rehabilitation services frequently fall short of including sexuality as a matter of routine. The literature was reviewed to examine the experiences of trauma survivors from three groups: spinal cord injury (SCI, traumatic brain injury (TBI and burns. The focus was on the impact of trauma on the QoL to identify future research directions and to advocate for the inclusion of sexuality as an integral part of rehabilitation. Databases searched were Proquest, Ovid, Cinahl, Medline, PsycInfo and Cochrane Central Register of controlled trials. A total of 36 eligible studies were included: SCI (n = 25, TBI (n = 6, burns (n = 5. Four themes were identified across the three trauma groups that were labeled as physiological impact of trauma on sexuality, cognitive-genital dissociation (CGD, sexual disenfranchisement (SD and sexual rediscovery (SR. Trauma injury has a significant impact on sexuality, which is not routinely addressed within rehabilitation services. Further sexuality research is required among all trauma groups to improve rehabilitation services and in turn QoL outcomes for all trauma survivors.

    Care of critically injured patients has evolved over the 50 years since Shoemaker established one of the first trauma units at Cook County Hospital in 1962. Modern trauma intensive care units offer a high nurse-to-patient ratio, physicians and midlevel providers who manage the patients, and technologically advanced monitors and therapeutic devices designed to optimize the care of patients. This article describes advances that have transformed trauma critical care, including bedside ultrasonography, novel patient monitoring techniques, extracorporeal support, and negative pressure dressings. It also discusses how to evaluate the safety and efficacy of future advances in trauma critical care. PMID:22850154

    Full Text Available In Italy, as in other western countries, trauma is a leading cause of death during the first four decades of life, with almost 18.000 of deaths per year. Since 80s organized systems for trauma care, including a pre-hospital emergency medical system and a network of hospitals designated as Trauma Centres, have been developed in north American countries. Effectiveness of trauma systems has been investigated comparing the post-system to the pre-system trauma care with the method of panel evaluation of preventable death rates and comparison of observed survival with expected probability of survival. In Italy, a pre-hospital emergency medical system has been implemented on a national scale, while a trauma network has not been developed. Nowadays, trauma patients are often admitted to the closest hospital, independently from local resources. The Superior Council of Ministry of Health has presented in 2004 a new trauma system model (SIAT based on the recognition in the field of patients with more serious injuries and the transportation to general hospitals with resources and multidisciplinary teams specialized in trauma care (trauma team. The designation of few trauma team hospitals, one highly specialized Centre (CTS and two area Centres (CTZ every two millions of inhabitants allows each Centre to treat at least 250 severe trauma patients per year to increase experience. Less severe injured patients may be treated in non-trauma team acute care facilities, according to the inclusive system model. The development of trauma team services in some Italian hospitals has demonstrated an increase in survival and a decrease in preventable death rate from 42% to 7,6%. Economic studies of Ministry of Health have established that the implementation of a trauma system model on a national scale with a 25% decrease of preventable trauma deaths and disabilities would save 7500 million of euros of public money. Therefore, in our country the concentration of severely

    2015-06-01

    Full Text Available Decolonizing trauma theory has been a major project in postcolonial literary scholarship ever since its first sustained engagements with trauma theory. Since then, trauma theory and postcolonial literary studies have been uneasy bedfellows, and the time has now come to take stock of what remains in postcolonial trauma studies from the original formulations of trauma theory, and see which further steps must be envisaged in order to reach the ideal of a truly decolonized trauma theory today. To this end, this article presents a detailed overview of the short history and the present situation of the trajectory of decolonizing trauma theory for postcolonial studies, clarifying the various re-routings that have so far taken place, and delineating the present state of the project, as well as the need for further developments towards an increased expansion and inclusiveness of the theory. I argue that openness to non-Western belief systems and their rituals and ceremonies in the engagement with trauma is needed in order to achieve the remaining major objectives of the long-standing project of decolonizing trauma theory.

  15. Structural complexes of the agonist, inverse agonist and antagonist bound C5a receptor: insights into pharmacology and signaling.

    2016-04-26

    The C5a receptor (C5aR) is a pharmacologically important G-protein coupled receptor (GPCR) that interacts with (h)C5a, by recruiting both the "orthosteric" sites (site1 at the N-terminus and site2 at the ECS, extra cellular surface) on C5aR in a two site-binding model. However, the complex pharmacological landscape and the distinguishing chemistry operating either at the "orthosteric" site1 or at the functionally important "orthosteric" site2 of C5aR are still not clear, which greatly limits the understanding of C5aR pharmacology. One of the major bottlenecks is the lack of an experimental structure or a refined model structure of C5aR with appropriately defined active sites. The study attempts to understand the pharmacology at the "orthosteric" site2 of C5aR rationally by generating a highly refined full-blown model structure of C5aR through advanced molecular modeling techniques, and further subjecting it to automated docking and molecular dynamics (MD) studies in the POPC bilayer. The first series of structural complexes of C5aR respectively bound to a linear native peptide agonist ((h)C5a-CT), a small molecule inverse agonist (NDT) and a cyclic peptide antagonist (PMX53) are reported, apparently establishing the unique pharmacological landscape of the "orthosteric" site2, which also illustrates an energetically distinct but coherent competitive chemistry ("cation-π" vs. "π-π" interactions) involved in distinguishing the established ligands known for targeting the "orthosteric" site2 of C5aR. Over a total of 1 μs molecular dynamics (MD) simulation in the POPC bilayer, it is evidenced that while the agonist prefers a "cation-π" interaction, the inverse agonist prefers a "cogwheel/L-shaped" interaction in contrast to the "edge-to-face/T-shaped" type π-π interactions demonstrated by the antagonist by engaging the F275(7.28) of the C5aR. In the absence of a NMR or crystallographically guided model structure of C5aR, the computational model complexes not only

    International Nuclear Information System (INIS)

    Simple abdomen film has played an important role in decision of emergency operations in patients with the abdominal trauma. Nowadays, it still acts as a primary and inevitable processes in emergency condition. At the Department of Radiology, Hanil Hospital, 70 patients, who were laparotomied due to penetrating or nonpernetraing abdominal trauma, were observed and analyzed with simple abdomen film after comparison with the operative findings. The results are as follows: 1. Most frequent age distribution was 10 to 39 years and marked 70%. Male was in 90% incidence. 2. Penetrating injury largely involved the small bowel and abdominal wall. Non-penetrating injury usually involved the spleen, small bowel, liver, kidney, pancreas, duodenum. 3. Single organ injury occurred in higher incidence at the small bowel and abdominal wall. Multiple organ injury occurred in higher incidence at the spleen, liver, kidney and pancreas. 4. Organ distribution was 26% in spleen, 22% in small bowel, 14% in liver, 11% in abdominal wall. 7% in pancreas, 7% in kidney. 5% in duodenum, 4% in GB and CBD, 2% in diaphragm, 2% in colon, and 1% in stomach. 5. The specific roentgen findings and their frequency which useful in differential diagnosis at abdominal trauma, were as follows: a) flank fluid; Detectable possibility was 71% in liver laceration, 69% in spleen laceration and 57% in pancreas laceration. b) ipsilateral psoas shadow obliteration; Detectable possibility was 57% in liver laceration, 57% in kidney laceration and 46% in spleen laceration. c) free air; Detactable possibility was 60% in duodenal perforation, and 36% in peroration of upper part of small bowel. d) Reflex ileus; Detectable possibility was 64% in small bowel, 50% in liver laceration and 35% in spleen laceration. e) rib fracture; Detactable possibility was 36% in liver laceration and 23% in spleen laceration. f) pleural effusion; Detectable possibility was 29% in liver laceration and 27% in spleen laceration

Desde fines de los años ochenta, se fueron destituyendo las dictaduras latinoamericanas, la mayoría sobre bases de consensos entre las fuerzas dictatoriales y los negociadores políticos de corrientes democráticas. La fuerza de los movimientos sociales sirvió de puente para las negociaciones, pero no logró estar del todo en las transacciones hacia los procesos de transición. Si así hubiera sido, la justicia y la verdad hubieran tenido un lugar privilegiado en los procesos denominados de "transición a las democracias" en distintos países del cono sur latinoamericano. La memoria colectiva ligada al trauma social tendrá varios componentes que abarcan también la memoria individual, incluyendo los espacios de la experiencia, propia y ajena. Este artículo pretende bucear en las interacciones entre ambos ámbitos de la memoria y sus conexiones con el tiempo presente.__________ABSTRACT:Social trauma and collective memory or collective memories are linked to the post-dictatorial Latin America. Since the late eighties, Latin American dictatorships were progressively dismissing, the majority on the basis of consensus between the dictatorial forces and the political mediators of the democratic part. The strength of social movements formed the bridge to negotiations, but could not entirely participate in the transactions to the transition process. If it would have been so, justice and truth would have had a special place in the process called "transition to democracy" in several Latin American Southern Cone countries. The collective memory linked to social trauma will have several components that also include individual memory, including personal and collective spaces of experience. This article aims to analyze the interactions between the two areas of memory and its connections to the present time.

    In some people an attack of migraine may be provoked by heading a football or a blow on the face in a rugby tackle. The attack is sometimes alarming and clearly cannot be explained on a basis of trauma alone. Some people only have attacks in this particular circumstance but the majority have spontaneous episodes at other times. The presentation is usually in childhood or early adult life. The syndrome is discussed in relation to reports of seven patients to illustrate the variations which include migraine without headache and persistent features after the attack. The condition is benign but may cause the patient to give up playing football. PMID:4095535

    Cephalopods show behavioral parallels to birds and mammals despite considerable evolutionary distance [1, 2]. Many cephalopods produce complex body patterns and visual signals, documented especially in cuttlefish and squid, where they are used both in camouflage and a range of interspecific interactions [1, 3-5]. Octopuses, in contrast, are usually seen as solitary and asocial [6, 7]; their body patterns and color changes have primarily been interpreted as camouflage and anti-predator tactics [8-12], though the familiar view of the solitary octopus faces a growing list of exceptions. Here, we show by field observation that in a shallow-water octopus, Octopus tetricus, a range of visible displays are produced during agonistic interactions, and these displays correlate with the outcome of those interactions. Interactions in which dark body color by an approaching octopus was matched by similar color in the reacting octopus were more likely to escalate to grappling. Darkness in an approaching octopus met by paler color in the reacting octopus accompanied retreat of the paler octopus. Octopuses also displayed on high ground and stood with spread web and elevated mantle, often producing these behaviors in combinations. This study is the first to document the systematic use of signals during agonistic interactions among octopuses. We show prima facie conformity of our results to an influential model of agonistic signaling [13]. These results suggest that interactions have a greater influence on octopus evolution than has been recognized and show the importance of convergent evolution in behavioral traits. PMID:26832440

    Full Text Available Abstract Severe trauma-related bleeding is associated with high mortality. Standard coagulation tests provide limited information on the underlying coagulation disorder. Whole-blood viscoelastic tests such as rotational thromboelastometry or thrombelastography offer a more comprehensive insight into the coagulation process in trauma. The results are available within minutes and they provide information about the initiation of coagulation, the speed of clot formation, and the quality and stability of the clot. Viscoelastic tests have the potential to guide coagulation therapy according to the actual needs of each patient, reducing the risks of over- or under-transfusion. The concept of early, individualized and goal-directed therapy is explored in this review and the AUVA Trauma Hospital algorithm for managing trauma-induced coagulopathy is presented.

    A case of recovered memory of childhood trauma is reported with documented sexual trauma in early childhood, chronicled evidence of the absence of memory for traumatic experience over a period of time, and substantial evidence of 'spontaneous' recovery of memory. This account contains the first available prospective report of memory loss in a case in which there is both documented evidence of trauma and evidence of recovery of memory. The case emerged as part of a broadband, large-scale study of children followed closely from birth to adulthood which was not focused on memory for trauma. Prospective data gathered in a neutral research context, corroborated and supplemented by retrospective information, circumvent many limitations of previous retrospective accounts of recovered memories.

    International Nuclear Information System (INIS)

    Traumatic lesions of the skeleton are common occurrences in everyday living and at all ages. The presence of a fracture upon clinical examination may or may not be obvious, thus leaving the radiological investigation as a focal point for definitive diagnosis. With today's sophisticated imaging system which render a minimal dosage of radiation to the patient, whenever there is any doubt concerning the presence of a fracture, radiographs should be performed. There may be severe medicolegal ramifications when fractures have been overlooked due to the lack of appropriate radiographs being taken or the oversight of the observer. When a fracture or dislocation is identified, key features must be evaluated. Successful treatment of fractures starts with accurate diagnosis, which requires a well-performed and accurately interpreted radiographic examination. The minimum examination is considered to be two radiographs at 90 degrees to each other; anything less is considered an incomplete examination. The purpose of this chapter is to familiarize the reader with the most common types of fractures and dislocations. The chapter is presented in a regional manner, with a preliminary presentation of descriptive terminology, definitions, and a review of fracture repair

    A new method for the detection of β2 adrenergic agonists was developed based on the chemiluminescence (CL) reaction of β2 adrenergic agonist with potassium ferricyanide-luminol CL. The effect of β2 adrenergic agonists including isoprenaline hydrochloride, salbutamol sulfate, terbutaline sulfate and ractopamine on the CL intensity of potassium ferricyanide-luminol was discovered. Detection of the β2 adrenergic agonist was carried out in a flow system. Using uniform design experimentation, the influence factors of CL were optimized. The optimal experimental conditions were 1 mmol/L of potassium ferricyanide, 10 µmol/L of luminol, 1.2 mmol/L of sodium hydroxide, a flow speed of 2.6 mL/min and a distance of 1.2 cm from 'Y2 ' to the flow cell. The linear ranges and limit of detection were 10-100 and 5 ng/mL for isoprenaline hydrochloride, 20-100 and 5 ng/mL for salbutamol sulfate, 8-200 and 1 ng/mL for terbutaline sulfate, 20-100 and 4 ng/mL for ractopamine, respectively. The proposed method allowed 200 injections/h with excellent repeatability and precision. It was successfully applied to the determination of three β2 adrenergic agonists in commercial pharmaceutical formulations with recoveries in the range of 96.8-98.5%. The possible CL reaction mechanism of potassium ferricyanide-luminol-β2 adrenergic agonist was discussed from the UV/vis spectra. PMID:24830367

    In the Netherlands, it is a tradition of setting off fireworks to celebrate the turn of the year. In our medical facility, each year patients with severe skeletal maxillofacial trauma inflicted by recreational fireworks are encountered. We present two cases of patients with severe blast injury to the face, caused by direct impact of rockets, and thereby try to contribute to the limited literature on facial blast injuries, their treatment, and clinical outcome. These patients require multidisciplinary treatment, involving multiple reconstructive surgeries, and the overall recovery process is long. The severity of these traumas raises questions about the firework traditions and legislations not only in the Netherlands but also worldwide. Therefore, the authors support restrictive laws on personal use of fireworks in the Netherlands. PMID:27162578

    Objective: To improving trauma nursing practice in Thailand and other countries. Methods:As part of a larger study of 164 ER nurses, 83 nurses provided narrative responses to questions of CNPG utilization and barriers to implementation. Using a qualitative descriptive design and analysis, three major themes were identified: Guidelines reflect good practice; Nurses do not always follow guidelines; and System problems limit use. Results: The results suggest optimized guideline adherence would require using judgment in following CNPG; ensuring organized teamwork is essential; and providing maximum resources would promote optimal care.Conclusion: Clinical nursing practice guidelines (CNPG) have been developed in Thailand for resuscitation care of emergency room (ER) trauma patients. However, many nurses do not use guidelines effectively.

    2015-06-01

    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: (i) basic science groundwork for future therapeutic candidates; (ii) development of acute coagulopathy scoring systems; (iii) coagulation factor composition-based computational analysis; (iv) characterization of novel analytes including tissue factor, polyphosphates, histones, meizothrombin and α-thrombin-antithrombin complexes, factor XIa, platelet and endothelial markers of activation, signatures of protein C activation and fibrinolysis markers; and (v) assessment of viscoelastic tests and new point-of-care methods.

    Patel, Alpen; Groppo, Eli

    2010-06-01

    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

    2016-03-01

    There is a global obesity epidemic that will continue to be a financial burden on healthcare systems around the world. Tackling obesity through diet and exercise should always be the first intervention, but this has not proved to be effective for a large number of patients. Pharmacotherapeutic options have been limited and many previously available drugs have been withdrawn due to safety concerns. Currently, only bariatric surgery has the capability to induce both substantial and durable weight loss. This article briefly reviews the history of pharmacotherapy for obesity before focusing on the clinical trial evidence for the use of the GLP-1 agonist liraglutide as a weight loss agent and comparing its efficacy with other emerging drug therapies for obesity.

    Kluft, Richard P

    2016-07-01

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

    Full Text Available This round-table, which featured literary critics Professor Stef Craps, Professor Bryan Cheyette and Dr. Alan Gibbs, was recorded as part of the “Decolonizing Trauma Studies” symposium organized by Dr. Sonya Andermahr and Dr. Larissa Allwork at The School of The Arts, The University of Northampton (15 May 2015. Convened a week after the University of Zaragoza’s “Memory Frictions” conference, where Cheyette, Gibbs, Andermahr and Allwork gave papers, the Northampton symposium and round-table was sponsored by The School of The Arts to coincide with Andermahr’s guest editorship of this special issue of Humanities. Craps, Cheyette and Gibbs addressed five questions during the round-table. Namely, does trauma studies suffer from a form of psychological universalism? Do you see any signs that trauma studies is becoming more decolonized? What are the challenges of a decolonized trauma studies for disciplinary thinking? How does a decolonized trauma studies relate to pedagogical ethics? Finally, where do you see the future of the field? While this edited transcript retains a certain informality of style, it offers a significant contribution to knowledge by capturing a unique exchange between three key thinkers in contemporary trauma studies, providing a timely analysis of the impact of postcolonial theory on trauma studies, the state of the field and its future possibilities. Issues addressed include the problematic scholarly tendency to universalize a western model of Post-Traumatic Stress Disorder (PTSD; the question of the centrality of the Holocaust in trauma studies and the implications of this for the study of atrocities globally; the vexed issues posed by the representation of perpetrators; as well as how the basic tenets of western cultural trauma theory, until recently so often characterized by a Caruth-inspired focus on belatedness and afterwardness, are being rethought, both in response to developments in the US and in answer to

    The misuse of β-agonists constitutes a potential risk to public health and has been forbidden in many countries. In this study, we describe a method for specific, sensitive and rapid detection of β-agonists in human urine. Urine samples were extracted with ethyl acetate, without any additional purification step, and analyzed by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS-MS) with Clenbuterol-D9 and Salbuterol-D3 as internal standards. The intra- and interday precision values of the method were all <5.60% and the accuracy ranged from 94.5 to 109%. Extraction recovery for 11 β-agonists varied from 66.7 to 108%. One UPLC-MS-MS analysis could be completed within 12 min and the limits of detection for 11 β-agonists were 0.1 ng/mL in the experiment. β-Agonists in human urines from 24 volunteers were analyzed by our validated method and 1.70 ng/mL salbutamol was detected in one volunteer. The application of UPLC-MS-MS method in β-agonists detection of human urine will be helpful in veterinary control of β-agonists and for studying the effect of β-agonists on human health.

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

  15. Computed tomography in hepatic trauma

    International Nuclear Information System (INIS)

    Twenty-five patients with hepatic injury from blunt upper abdominal trauma were examined by computed tomography (CT). The spectrum of CT findings was recorded, and the size of the hepatic laceration and the associated hemoperitoneum were correlated with the mode of therapy used in each case (operative vs nonoperative). While the need for surgery correlated roughly with the size of the hepatic laceration, the size of the associated hemoperitoneum was an important modifying factor. Fifteen patients with hepatic lacerations but little or no hemoperitoneum were managed nonoperatively. CT seems to have significant advantages over hepatic scintigraphy, angiography, and diagnostic peritoneal lavage. By combining inforamtion on the clinical state of the patient and CT findings, therapy of hepatic injury can be individualized and the incidence of nontherapeutic laparotomies decreased

    Full Text Available Abstract Background Quality control of trauma care is essential to define the effectiveness of trauma center and trauma system. To identify the troublesome issues of the system is the first step for validation of the focused customized solutions. This is a comparative study of two level I trauma centers in Italy and Romania and it has been designed to give an overview of the entire trauma care program adopted in these two countries. This study was aimed to use the results as the basis for recommending and planning changes in the two trauma systems for a better trauma care. Methods We retrospectively reviewed a total of 182 major trauma patients treated in the two hospitals included in the study, between January and June 2002. Every case was analyzed according to the recommended minimal audit filters for trauma quality assurance by The American College of Surgeons Committee on Trauma (ACSCOT. Results Satisfactory yields have been reached in both centers for the management of head and abdominal trauma, airway management, Emergency Department length of stay and early diagnosis and treatment. The main significant differences between the two centers were in the patients' transfers, the leadership of trauma team and the patients' outcome. The main concerns have been in the surgical treatment of fractures, the outcome and the lacking of documentation. Conclusion The analyzed hospitals are classified as Level I trauma center and are within the group of the highest quality level centers in their own countries. Nevertheless, both of them experience major lacks and for few audit filters do not reach the mmum standard requirements of ACS Audit Filters. The differences between the western and the eastern European center were slight. The parameters not reaching the minimum requirements are probably occurring even more often in suburban settings.

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

    International Nuclear Information System (INIS)

    Chest trauma in childhood is relatively uncommon in clinical practice andhas been the subject of few reports in literature. This study was undertakento examine our experience in dealing with chest trauma in children. This wasa retrospective study of 74 children who sustained chest trauma and werereferred to King Fahd Hospital in Medina over a two-year period. The age,cause of injury, severity of injury, associated extrathoracic injuries,treatment and outcome were analyzed. The median age of patients was nineyears. Fifty-nine of them (80%) sustained blunt trauma in 62% of thechildren, gun shot wounds were seen in five and stab wounds in 10 children.Head injury was the most common injury associated with thoracic trauma andwas seen in 14 patients (19%) and associated intra-abdominal injuries wereseen in nine patients. Chest x-ray of the blunt trauma patients revealedfractured ribs in 24 children, pneumothorax in six, hemothorax in four,hemoneumothorax in three, and pulmonary contusions in 22 patients. Fifty onepercent of children were managed conservatively, 37% required tubethoracostomy, 8% were mechanically ventilated and 4% underwent thoractomy.The prevalence of chest trauma in children due to road traffic accidents ishigh in Saudi Arabia. Head injury is thought to be the most common associatedextrathoracic injuries, however, most of these patients can be managedconservatively. (author)

    Several {beta}{sub 2} adrenergic agonists are illegally used as growth promoters in meat production. We have developed and evaluated a radioreceptor assay for the multianalyte detection of these compounds. The method is based on a competition for binding with receptors (plasma membranes prepared from bovine teat muscles) between a radioactive tracer ({sup 3}H-dihydroalprenolol) and {beta}{sub 2} agonist residues present in the samples. The method has been validated for three {beta}{sub 2} agonists (clenbuterol, mabuterol and cimaterol) in bovine urine samples. The detection limit (mean of ``blank`` values + 3 SEM) in urine was 2.4 ppb clenbuterol. Using this procedure, samples containing at least 5 ppb of clenbuterol, mabuterol or cimaterol could be identified as positive for the presence of {beta}{sub 2} agonists. (orig.) [Deutsch] Mehrere {beta}{sub 2} adrenerge Agonisten werden illegal als Wachstumsfoerderer in der Fleischproduktion eingesetzt.

    Diabetic nephropathy (DN) is a severe complication of diabetes and serves as the leading cause of chronic renal failure. In the past decades, angiotensin-converting enzyme inhibitors (ACEIs)/angiotensin II receptor blockers (ARBs) based first-line therapy can slow but cannot stop the progression of DN, which urgently requests the innovation of therapeutic strategies. Thiazolidinediones (TZDs), the synthetic exogenous ligands of nuclear receptor peroxisome proliferator-activated receptor- γ (PPAR γ ), had been thought to be a promising candidate for strengthening the therapy of DN. However, the severe adverse effects including fluid retention, cardiovascular complications, and bone loss greatly limited their use in clinic. Recently, numerous novel PPAR γ agonists involving the endogenous PPAR γ ligands and selective PPAR γ modulators (SPPARMs) are emerging as the promising candidates of the next generation of antidiabetic drugs instead of TZDs.

    Full Text Available Diabetic nephropathy (DN is a severe complication of diabetes and serves as the leading cause of chronic renal failure. In the past decades, angiotensin-converting enzyme inhibitors (ACEIs/angiotensin II receptor blockers (ARBs based first-line therapy can slow but cannot stop the progression of DN, which urgently requests the innovation of therapeutic strategies. Thiazolidinediones (TZDs, the synthetic exogenous ligands of nuclear receptor peroxisome proliferator-activated receptor-γ (PPARγ, had been thought to be a promising candidate for strengthening the therapy of DN. However, the severe adverse effects including fluid retention, cardiovascular complications, and bone loss greatly limited their use in clinic. Recently, numerous novel PPARγ agonists involving the endogenous PPARγ ligands and selective PPARγ modulators (SPPARMs are emerging as the promising candidates of the next generation of antidiabetic drugs instead of TZDs. Due to the higher selectivity of these novel PPARγ agonists on the regulation of the antidiabetes-associated genes than that of the side effect-associated genes, they present fewer adverse effects than TZDs. The present review was undertaken to address the advancements and the therapeutic potential of these newly developed PPARγ agonists in dealing with diabetic kidney disease. At the same time, the new insights into the therapeutic strategies of DN based on the PPARγ agonists were fully addressed.

    Full Text Available Abstract Background Mortality from trauma remains a major public health issue as it is the leading cause of death in persons aged 5 to 44 years .Uncontrolled hemorrhage and coagulopathy is responsible for over 50% of all trauma related deaths within the first 48hrs of admission. Coagulation profiles are not routinely done among trauma patients in resource limited settings and there is a paucity of data on acute traumatic coagulopathy (ATC in sub Saharan Africa. The study was conducted to evaluate the prothrombin time and partial thromboplastin time (PT/PTT as predictors of mortality and morbidity among major trauma patients. Methods A prospective cohort study was carried out, in which major trauma patients admitted in A&E department between December 2011 to April 2012 were recruited. Five (5 mls of venous blood was drawn from a convenient vein within 10 minutes of the patient’s arrival at A&E for analysis of PT/PTT. Patients were stratified into two groups by the presence/absence of coagulopathy then followed up for a 2 week period for morbidity and mortality. Results A total of 182 major trauma patients were recruited; 149 (81.9% were males, the mean age was 29.5 years (SD 9.8. Prevalence of coagulopathy was 54% (98/182. The mean ISS for the ATC group was 36.9 and the non ATC group was 26.9 (p=0.001. Patients with ATC stayed longer in hospital 11.24 days than non ATC patients 8 days (p=0.001. ATC was strongly associated with ARI (p= 0.003. Mortality was more in the ATC group 29 deaths compared to 9 deaths in the non ATC group. PTT was a strong independent predictor of mortality. Conclusion A significant proportion of major trauma patients were coagulopathic. Initial coagulation profile is useful in predicting outcomes for major trauma patients.

  5. diagnostic imaging of acute head trauma

    International Nuclear Information System (INIS)

    Computed tomography (CT) is the primary modality of choice for imaging patients with acute head trauma. Lesions of the soft tissues and of the bones can be assessed more precisely than with other imaging modalities. With magnetic resonance imaging (MRI) additional information may be gained especially in subacute and chronic posttraumatic conditions. Urgent indication to perform a CT examination depends on the patient's history and on the mechanism of trauma. Imaging interpretation has been performed in the context of typical pathologic effects of trauma and with respect to potential therapy. (author)

    Trauma is the most common cause of death in childhood, and abusive head trauma is the most common cause of traumatic death and morbidity in infants younger than 1 year. The main differential diagnosis of abusive head trauma is accidental traumatic brain injury, which is usually witnessed. This paper also discusses more uncommon diagnoses such as congenital and acquired disorders of hemostasis, cerebral arteriovenous malformations and metabolic diseases, all of which are extremely rare. Diagnostic imaging including CT and MRI is very important for the distinction of non-accidental from accidental traumatic injury. (orig.)

    The author analyzes recent developments in trauma theory, made necessary especially after the massive psychic traumas following World War II and the Shoah. The theories of Freud and Ferenczi are analyzed, especially, their different views of reality and their clinical attitude. When working with survivors of any trauma (from incest to genocide) it is necessary to reconstruct the historical details as carefully as possible, with the appropriate timing. Psychoanalysis is therefore viewed as an ethical and political practice similar to testimony, allowing the reconstruction of truth within the community and interrupting the cycle of the death instinct from one generation to the next.

  9. A survey analysis of acoustic trauma related to MR scans

    International Nuclear Information System (INIS)

    The maximum limit of MR scanner noise and necessity of ear protection is defined in the IEC standard (IEC60601-2-33) of MR safety. With improvements in MR scanner performance, pulse sequences generating higher scanning noise have been used clinically. In this study, we investigated the factors significantly related to potential acoustic trauma cases (PATC) after MR examinations. To consider the future direction for MR safety and prevention of acoustic trauma, issues related to noise generation by MR scanners and acoustic trauma were systematically reviewed. A statistical analysis was performed using the data set from a survey (n=974) conducted in 2010 by the Japanese Society for Magnetic Resonance in Medicine (JSMRM) safety committee. Hierarchical clustering analysis was used to extract the characteristics of the responders. With this classification as a reference, tests of independence and a residual analysis were employed to evaluate the factors related to PATC. No significant relationship was observed between the ear protection policy and the incidence or the reported outcome of PATC. While the two main clusters out of the six clusters extracted were associated with who reported the PATC and the confirmation process of the acoustic noise level of MR scanners, no cluster was associated with the frequency of PATC. An absence of PATC was significantly less reported (p=0.03) and more PATC was reported (p=0.04) by facilities with 3T MR systems. Although the total frequency was 4 cases, it should be noted that persistent hearing disturbances are a possible consequence of MR examinations. Neither the condition of the subjects nor the ear protection method was significantly related to the probability of PATC, suggesting the difficulty of predicting the potential risk of acoustic trauma. It is recommended to more systematically follow up PATC cases and clarify the risk factors. (author)

    2015-01-01

    Farnesoid X receptors (FXRs) are nuclear hormone receptors expressed in high amounts in body tissues that participate in bilirubin metabolism including the liver, intestines, and kidneys. Bile acids (BAs) are the natural ligands of the FXRs. FXRs regulate the expression of the gene encoding for cholesterol 7 alpha-hydroxylase, which is the rate-limiting enzyme in BA synthesis. In addition, FXRs play a critical role in carbohydrate and lipid metabolism and regulation of insulin sensitivity. FXRs also modulate live growth and regeneration during liver injury. Preclinical studies have shown that FXR activation protects against cholestasis-induced liver injury. Moreover, FXR activation protects against fatty liver injury in animal models of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), and improved hyperlipidemia, glucose intolerance, and insulin sensitivity. Obeticholic acid (OCA), a 6α-ethyl derivative of the natural human BA chenodeoxycholic acid (CDCA) is the first-in-class selective FXR agonist that is ~100-fold more potent than CDCA. Preliminary human clinical trials have shown that OCA is safe and effective. In a phase II clinical trial, administration of OCA was well-tolerated, increased insulin sensitivity and reduced markers of liver inflammation and fibrosis in patients with type II diabetes mellitus and NAFLD. In two clinical trials of OCA in patients with primary biliary cirrhosis (PBC), a progressive cholestatic liver disease, OCA significantly reduced serum alkaline phosphatase (ALP) levels, an important disease marker that correlates well with clinical outcomes of patients with PBC. Together, these studies suggest that FXR agonists could potentially be used as therapeutic tools in patients suffering from nonalcoholic fatty and cholestatic liver diseases. Larger and Longer-term studies are currently ongoing. PMID:25705637

  12. Theory of partial agonist activity of steroid hormones

    Directory of Open Access Journals (Sweden)

    Carson C. Chow

    2015-04-01

    Full Text Available The different amounts of residual partial agonist activity (PAA of antisteroids under assorted conditions have long been useful in clinical applications but remain largely unexplained. Not only does a given antagonist often afford unequal induction for multiple genes in the same cell but also the activity of the same antisteroid with the same gene changes with variations in concentration of numerous cofactors. Using glucocorticoid receptors as a model system, we have recently succeeded in constructing from first principles a theory that accurately describes how cofactors can modulate the ability of agonist steroids to regulate both gene induction and gene repression. We now extend this framework to the actions of antisteroids in gene induction. The theory shows why changes in PAA cannot be explained simply by differences in ligand affinity for receptor and requires action at a second step or site in the overall sequence of reactions. The theory also provides a method for locating the position of this second site, relative to a concentration limited step (CLS, which is a previously identified step in glucocorticoid-regulated transactivation that always occurs at the same position in the overall sequence of events of gene induction. Finally, the theory predicts that classes of antagonist ligands may be grouped on the basis of their maximal PAA with excess added cofactor and that the members of each class differ by how they act at the same step in the overall gene induction process. Thus, this theory now makes it possible to predict how different cofactors modulate antisteroid PAA, which should be invaluable in developing more selective antagonists.

  13. Strategies for designing synthetic immune agonists.

    Wu, Tom Y-H

    2016-08-01

    Enhancing the immune system is a validated strategy to combat infectious disease, cancer and allergy. Nevertheless, the development of immune adjuvants has been hampered by safety concerns. Agents that can stimulate the immune system often bear structural similarities with pathogen-associated molecular patterns found in bacteria or viruses and are recognized by pattern recognition receptors (PRRs). Activation of these PRRs results in the immediate release of inflammatory cytokines, up-regulation of co-stimulatory molecules, and recruitment of innate immune cells. The distribution and duration of these early inflammatory events are crucial in the development of antigen-specific adaptive immunity in the forms of antibody and/or T cells capable of searching for and destroying the infectious pathogens or cancer cells. However, systemic activation of these PRRs is often poorly tolerated. Hence, different strategies have been employed to modify or deliver immune agonists in an attempt to control the early innate receptor activation through temporal or spatial restriction. These approaches include physicochemical manipulation, covalent conjugation, formulation and conditional activation/deactivation. This review will describe recent examples of discovery and optimization of synthetic immune agonists towards clinical application. PMID:27213842

    The unwanted psychoactive effects of cannabinoid receptor agonists have limited their development as medicines. These CB1 mediated side effects are due to the fact that CB1 receptors are largely expressed in the Central Nervous System (CNS). Since it is known that CB1 receptors are also located peripherally, there is a growing interest in targeting cannabinoid receptors located outside the brain. A library of chromenopyrazoles designed in analogy to the classical cannabinoid cannabinol were s...

  17. Trauma-induced insomnia: A novel model for trauma and sleep research.

    Science.gov (United States)

    Sinha, Smit S

    2016-02-01

    Traumatic events have been increasingly recognized as important precipitants of clinically significant insomnia. Trauma is an extreme form of stressful life event that generates a sustained neurobiological response triggering the onset and maintenance of insomnia. Trauma may disrupt the normal sleep-wake regulatory mechanism by sensitizing the central nervous system's arousal centers, leading to pronounced central and physiological hyperarousal. The central concept of hyperarousal has been linked to both the pathogenesis of insomnia and to the neurobiological changes in the aftermath of traumatic events, and may be a neurobiological commonality underlying trauma and insomnia. This paper presents evidence for trauma-induced insomnia and advances a model of it as an important nosological and neurobiological entity. Trauma-induced insomnia may occur in the absence of full-blown posttraumatic stress disorder (PTSD), and may also be a precursor of subsequent PTSD development. Converging lines of evidence from the neuroscience of insomnia with the neurobiology and psychophysiology of stress, fear, trauma and PTSD will be integrated to advance understanding of the condition. Preclinical and clinical stress and fear paradigms have informed the neurobiological pathways mediating the production of insomnia by trauma. Elucidating the underlying neurobiological substrates can establish novel biological markers to identify persons at risk for the condition, and help optimize treatment of the trauma-insomnia interface. Early identification and treatment of trauma-induced insomnia may prevent the development of PTSD, as well as other important sequelae such as depression, substance dependence, and other medical conditions.

    Full Text Available Aim. We investigated perceptions of a new smartphone application (app as a learning resource. Methods. We developed TraumaTutor, an iPhone app consisting of 150 questions and explanatory answers on trauma management. This was used by 20 hospital staff that either had a special interest in managing trauma or who were studying for relevant exams, such as ATLS. A subsequent questionnaire assessed users’ experience of smartphone applications and their perceptions of TraumaTutor. Results. Of those surveyed, 85% had a device capable of running app software, and 94% of them had used apps for medical education. Specific to TraumaTutor, 85% agreed that it was pitched at the right level, 95% felt that the explanations improved understanding of trauma management, and 100% found the app easy to use. In fact, on open questioning, the clear user interface and the quality of the educational material were seen as the major advantages of TraumaTutor, and 85% agreed that the app would be a useful learning resource. Conclusions. Smartphone applications are considered a valuable educational adjunct and are commonly used by our target audience. TraumaTutor shows overwhelming promise as a learning supplement due to its immediacy, accessibility, and relevance to those preparing for courses and managing trauma.

    In order to find the mechanism of superior clunial nerve (SCN) trauma, we dissected and revealed SCN from 12 corpses (24 sides). Combining 100 sides of SCN trauma, we inspected the course of SCN, the relation between SCN and it's neighbour tissues with the situation of SCN when being subjected to force. We found that the following special anatomic characteristics and mechanical elements such as the course of SCN, it's turning angles, the bony fibrous tube at the iliac crest, the posterior layer of the lumbodorsal fascia and SCN neighbour adipose tissue, are the causes of external force inducing SCN trauma. The anatomic revealment is the guidance of SCN trauma treatment with edged needle.

  2. Adhesive intestinal obstruction following blunt abdominal trauma

    International Nuclear Information System (INIS)

    Advances in diagnosis and management of multiple trauma patients have lead to adopting a conservative approach for most patients with blunt abdominal trauma. Intestinal obstruction is a rare complication for this approach. Herein, we report a 37-year-old male, who did not have an abdominal operation, and who developed adhesive intestinal obstruction 7 weeks following blunt abdominal trauma. We detected no signs of peritonitis or intra-abdominal bleeding clinically or radiologically on admission. We initially treated the intestinal obstruction conservatively, but the obstruction did not resolve. Finally, we performed laparotomy, which showed that the small bowel was matted together by thick fibrous layers of adhesions. We performed adhesiolysis, and the patient was discharged home 3 weeks later. Histopathological findings of the fibrous layer were consistent with repair due to previous trauma and hemorrhage. We review the literature of this rare condition. (author)

  3. Evidence-based diagnosis of abdominal trauma

    International Nuclear Information System (INIS)

    Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a ''focused assessment with sonography for trauma'' (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for ''wait and see'' treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences. (orig.)

  4. Changing spleen size after blunt abdominal trauma

    International Nuclear Information System (INIS)

    The authors studied the incidence and significance of splenic enlargement on serial CT after abdominal trauma. Spleen size and density in 44 trauma patients were studied with serial, contrast-enhanced Ct. In 58% of the patients, ≥ 10% enlargement of the spleen was seen on follow-up scans. Ten patients had >50% enlargement. In several, the initial density of the spleen was less than that of the liver. Spleen density returned to normal on subsequent scans. Correlations between splenic changes and clinical parameters (such as blood replacement, hypotension, and various trauma indexes) were weak. The author's study indicated that serial splenic enlargement was a physiologic return to normal after major trauma, not a pathologic condition requiring splenectomy

    Full Text Available Abstract Background Computed tomography (CT scanning has become essential in the early diagnostic phase of trauma care because of its high diagnostic accuracy. The introduction of multi-slice CT scanners and infrastructural improvements made total-body CT scanning technically feasible and its usage is currently becoming common practice in several trauma centers. However, literature provides limited evidence whether immediate total-body CT leads to better clinical outcome then conventional radiographic imaging supplemented with selective CT scanning in trauma patients. The aim of the REACT-2 trial is to determine the value of immediate total-body CT scanning in trauma patients. Methods/design The REACT-2 trial is an international, multicenter randomized clinical trial. All participating trauma centers have a multi-slice CT scanner located in the trauma room or at the Emergency Department (ED. All adult, non-pregnant, severely injured trauma patients according to predefined criteria will be included. Patients in whom direct scanning will hamper necessary cardiopulmonary resuscitation or who require an immediate operation because of imminent death (both as judged by the trauma team leader are excluded. Randomization will be computer assisted. The intervention group will receive a contrast-enhanced total-body CT scan (head to pelvis during the primary survey. The control group will be evaluated according to local conventional trauma imaging protocols (based on ATLS guidelines supplemented with selective CT scanning. Primary outcome will be in-hospital mortality. Secondary outcomes are differences in mortality and morbidity during the first year post trauma, several trauma work-up time intervals, radiation exposure, general health and quality of life at 6 and 12 months post trauma and cost-effectiveness. Discussion The REACT-2 trial is a multicenter randomized clinical trial that will provide evidence on the value of immediate total-body CT scanning

  20. CT detection of occult pneumothorax in head trauma

    International Nuclear Information System (INIS)

    A prospective evaluation for occult pneumothorax was performed in 25 consecutive patients with serious head trauma by combining a limited chest CT examination with the emergency head CT examination. Of 21 pneuomothoraces present in 15 patients, 11 (52%) were found only by chest CT and were not identified clinically or by supine chest radiograph. Because of pending therapeutic measures, chest tubes were placed in nine of the 11 occult pneumothoraces, regardless of the volume. Chest CT proved itself as the most sensitive method for detection of occult pneumothorax, permitting early chest tube placement to prevent transition to a tension pneumothorax during subsequent mechanical ventilation or emergency surgery under general anesthesia

    Peroxisome Proliferator-Activated Receptor-γ (PPARγ) is a ligand-activated nuclear hormone receptor that functions as transcription factor and plays an important role in lipid metabolism and insulin sensitization. Recent studies have shown that PPARγ is overexpressed in many tumor types, including cancers of breast, lung, pancreas, colon, glioblastoma, prostate and thyroid differentiated/anaplastic cancers. These data suggest a role of PPARγ in tumor development and/or progression. PPARγ is emerging as a growth-limiting and differentiation-promoting factor, and it exerts a tumor suppressor role. Moreover, naturally-occurring and synthetic PPARγ agonists promote growth inhibition and apoptosis. Thiazolidinediones (TZDs) are synthetic agonists of PPARγ that were developed to treat type II diabetes. These compounds also display anticancer effects which appear mainly to be independent of their PPARγ agonist activity. Various preclinical and clinical studies strongly suggest a role for TZDs both alone and in combination with existing chemotherapeutic agents, for the treatment of cancer. Differentiation therapy involves the use of agents with the ability to induce differentiation in cells that have lost this ability, i.e. cancer cells, targeting pathways capable of re-activating blocked terminal differentiation programs. PPARγ agonists have been shown to induce differentiation in solid tumors such as thyroid differentiated/ anaplastic cancers and sarcomas. However, emerging data suggest that chronic use of TZDs is associated with increased risk of adverse cardiovascular events. The exploration of newer PPARγ agonists can help in unveiling the underlying mechanisms of these drugs, providing new molecules that are able to treat cancer, without increasing the cardiovascular risk of neoplastic patients.

    Full Text Available Monoamines, such as 5-HT and tyramine (TA, paralyze both free-living and parasitic nematodes when applied exogenously and serotonergic agonists have been used to clear Haemonchus contortus infections in vivo. Since nematode cell lines are not available and animal screening options are limited, we have developed a screening platform to identify monoamine receptor agonists. Key receptors were expressed heterologously in chimeric, genetically-engineered Caenorhabditis elegans, at sites likely to yield robust phenotypes upon agonist stimulation. This approach potentially preserves the unique pharmacologies of the receptors, while including nematode-specific accessory proteins and the nematode cuticle. Importantly, the sensitivity of monoamine-dependent paralysis could be increased dramatically by hypotonic incubation or the use of bus mutants with increased cuticular permeabilities. We have demonstrated that the monoamine-dependent inhibition of key interneurons, cholinergic motor neurons or body wall muscle inhibited locomotion and caused paralysis. Specifically, 5-HT paralyzed C. elegans 5-HT receptor null animals expressing either nematode, insect or human orthologues of a key Gαo-coupled 5-HT1-like receptor in the cholinergic motor neurons. Importantly, 8-OH-DPAT and PAPP, 5-HT receptor agonists, differentially paralyzed the transgenic animals, with 8-OH-DPAT paralyzing mutant animals expressing the human receptor at concentrations well below those affecting its C. elegans or insect orthologues. Similarly, 5-HT and TA paralyzed C. elegans 5-HT or TA receptor null animals, respectively, expressing either C. elegans or H. contortus 5-HT or TA-gated Cl- channels in either C. elegans cholinergic motor neurons or body wall muscles. Together, these data suggest that this heterologous, ectopic expression screening approach will be useful for the identification of agonists for key monoamine receptors from parasites and could have broad application for

    Full Text Available Objective: The aim of this study was to determine the presence of clinical and radiographic signs of injury to the maxillary primary incisors and the children carers' knowledge about dental trauma ocurrence in a 45 children group from three to eight years old. Method: Before the clinical examination, the carers were asked about their children's dental trauma events. After that, took course the maxillary incisors clinical and radiographical examination, excluding the ones with caries, fillings, or pulpar treatments. Results: Discoloration (50.0% was the most common present sign of trauma followed by avulsion (17.6% and the pulp canal obliteration (56.3% was the major result of the radiographical signal. Boys had more trauma recorded than girls and the maxillary central incisors were the most vulnerable to injury. Besides, the amount of trauma recorded by clinical and radiographic examination was bigger than that reported in the questionnaire by mothers or children carers. Conclusion: The results related in this study reinforce the need of immediate attention to trauma on deciduous dentition and long term observation of the developing permanent successor.

Conclusions: The study suggests emphasis on psychosocial aspects in ICU care for optimizing prognosis.

  5. Head trauma in female professional wrestlers

    International Nuclear Information System (INIS)

    The clinical characteristics of head trauma were evaluated in 18 wrestlers belonging to a female professional wrestling organization, 13 regular members and five trainees aged 15-34 years. Medical examinations for head trauma were performed in all wrestlers, and wrestlers treated at our emergency outpatient department were clinically evaluated. In addition, the relationships of head trauma with duration of the wrestling career of 1-16 years (mean 8 years) in the regular members, and less than 1 year in the five trainees, and body mass index (BMI) of 21.0-32.0 in the 16 subjects, excluding two trainees, was evaluated. Chronic symptoms were noted in four of the 18 wrestlers with long wrestling careers (16 years in 1, 13 years in 1, and 5 years in 2). Three wrestlers with symptoms immediately after head trauma showed recurrent retrograde amnesia and had low BMI (21.6, 21.6, and 23.1). Five wrestlers were treated at our emergency outpatient clinic, three required hospitalization and two showed intracranial traumatic changes on computed tomography (acute subdural hematoma in 1 and diffuse brain swelling in 1). Head trauma in female professional wrestlers is associated with longer wrestling career and low BMI. Periodic medical examinations are recommended to monitor for signs of head trauma. (author)

    2016-06-01

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

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

    Full Text Available Abstract Background The consequence of the low rate of penetrating injuries in Europe and the increase in non-operative management of blunt trauma is a decrease in surgeons' confidence in managing traumatic injuries has led to the need for new didactic tools. The aim of this retrospective study was to present the Corso di Chirurgia del Politrauma (Trauma Surgery Course, developed as a model for teaching operative trauma techniques, and assess its efficacy. Method the two-day course consisted of theoretical lectures and practical experience on large-sized swine. Data of the first 126 participants were collected and analyzed. Results All of the 126 general surgeons who had participated in the course judged it to be an efficient model to improve knowledge about the surgical treatment of trauma. Conclusion A two-day course, focusing on trauma surgery, with lectures and life-like operation situations, represents a model for simulated training and can be useful to improve surgeons' confidence in managing trauma patients. Cooperation between organizers of similar initiatives would be beneficial and could lead to standardizing and improving such courses.

    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.

  10. COMPARTMENT SYNDROME IN TRAUMA PATIENTS

    2007-07-01

    Full Text Available Acute limb compartment syndrome (LCS is a limb-threatening and occasionally life-threatening condition caused by bleeding or edema in a closed muscle compartment surrounded by fascia and bone, which leads to muscle and nerve ischemia. Well-known causative factors are acute trauma and reperfusion after treatment for acute arterial obstruction. Untreated compartment syndrome usually leads to muscle necrosis, limb amputation, and, if severe, in large compartments, renal failure and death. Alertness, clinical suspicion of the possibility of LCS, and occasionally intracompartmental pressure (ICP measurement are required to avoid a delay in diagnosis or missed diagnosis. Open fasciotomy, by incising both skin and fascia, is the most reliable method for adequate compartment decompression. The techniques of measuring ICP have advantages and disadvantages, whereas the pressure level that mandates fasciotomy is controversial. Increased awareness of the syndrome and the advent of measurements of ICP pressure have raised the possibility of early diagnosis and treatment. This presentation reports LCS, including etiology, diagnosis, ICP measurement, management, and outcome.

  11. Amniotic membrane for burn trauma

    International Nuclear Information System (INIS)

    Amniotic membranes are derived from human placentae at birth. They have two layers mainly the amniotic and the chorionic surfaces which are separated by a thin layer of connective tissues. The two layers are separated during procurement, the placenta and the chorionic side are discarded and the amnion membranes are then further processed. Amnion membranes are normally procured from placentae which are normally free of infections, i.e; the mothers are antenatally screened for sexually transmitted diseases or AlDs related diseases. Intrapartum the mother should not be having chorioamnionitis or jaundice. Sometimes the amniotic membranes are acquired from fresh elective caeserian sections. After processing, the amniotic membranes are packed in two layers of polypropylene and radiated with cobalt 60 at a dose of about 25 kGy. The amniotic membranes are clinically used to cover burn surfaces especially effective for superficial or partial thickness burns. The thin membranes adhered well to the trauma areas and peeled off automatically by the second week. No change of dressing were necessary during these times because of the close adherence, there were less chance of external contamination or infections of these wounds. Due to their flexibility they are very useful to cover difference contours of the human body for example the face, body, elbows or knees. However our experience revealed that amniotic membranes are not useful for third degree bums because the membranes dissolves by the enzymes present in the wounds

  17. Adverse effects of beta-agonists: are they clinically relevant?

    Science.gov (United States)

    Abramson, Michael J; Walters, Julia; Walters, E Haydn

    2003-01-01

    Inhaled beta(2)-adrenoceptor agonists (beta(2)-agonists) are the most commonly used asthma medications in many Western countries. Minor adverse effects such as palpitations, tremor, headache and metabolic effects are predictable and dose related. Time series studies suggested an association between the relatively nonselective beta-agonist fenoterol and asthma deaths. Three case-control studies confirmed that among patients prescribed fenoterol, the risk of death was significantly elevated even after controlling for the severity of asthma. The Saskatchewan study not only found an increased risk of death among patients dispensed fenoterol, but also suggested this might be a class effect of beta(2)-agonists. However, in subsequent studies, the long-acting beta(2)-agonist salmeterol was not associated with increased asthma mortality. In a case-control study blood albuterol (salbutamol) concentrations were found to be 2.5 times higher among patients who died of asthma compared with controls. It is speculated that such toxic concentrations could cause tachyarrhythmias under conditions of hypoxia and hypokalemia. The risk of asthma exacerbations and near-fatal attacks may also be increased among patients dispensed fenoterol, but this association may be largely due to confounding by severity. Although salmeterol does not appear to increase the risk of near-fatal attacks, there is a consistent association with the use of nebulized beta(2)-agonists. Nebulized and oral beta(2)-agonists are also associated with an increased risk of cardiovascular death, ischemic heart disease and cardiac failure. Caution should be exercised when first prescribing a beta-agonist for patients with cardiovascular disease. A potential mechanism for adverse effects with regular use of beta(2)-agonists is tachyphylaxis. Tachyphylaxis to the bronchodilator effects of long-acting beta(2)-agonists can occur, but has been consistently demonstrated only for formoterol (eformoterol) a full agonist, rather

    To determine the frequency and causes of bilateral ocular trauma. All patients coming to the hospital with bilateral eye trauma and requiring admission were recruited into the study. The details of patients demographics, risk factors, ocular examination, treatment offered and final visual acuity were noted and described as frequency and percentages. Out of a total of 1551 patients of hospitalized ocular trauma, 46 (2.9%, 92 eyes) had bilateral ocular trauma. The majority (54.3%) were due to landmine blast injuries followed by dynamite blast in 10.8%, coalmine blast and firearm injury in 6.5% each. Pressure cooker explosion and road traffic accident was the cause in 4.3% each. Gas cylinder and automobile battery explosion, alkali and acid burn, assault and incidental trauma occurred in 2.1%. Sixty three percent were between 16 and 40 years of age. Males were affected in 93.4%. Corneal and / or scleral repair was done in 58.6%, conjunctival and or corneal foreign body removal in 26% and extracapular cataract extraction with intraocular lens implantation in 16.3%. The visual acuity was in the range of 6/60 and perception of light in 54.3%, while in 21.7%, there was no perception of light at the time of admission. Due to severity of injury, the final visual acuity was poor and only 28.2% regained vision between 6/18 and 6/60. In this series, landmine, dynamite and coalmine blasts were the major causes of bilateral ocular trauma. Victims were usually young males. Due to severity of ocular trauma, majority had poor visual outcome. (author)

    2015-08-01

    Traumatic experiences can lead to a range of mental health problems with posttraumatic stress disorder (PTSD) leading as the most documented disorder following trauma. Epidemiological research has found the rate of exposure to trauma to far outweigh the prevalence of PTSD. Indicating that most people do not develop PTSD following a traumatic event, this phenomenon has led to an interest in evaluating risk factors to determine who develops PTSD. Risk factors for the development of psychopathology following trauma exposure fall into three categories: pre-trauma, peri-trauma and post-trauma factors. Pre-trauma factors can include age, gender, race/ethnicity, education, prior psychopathology, and neurobiological factors. Peri-trauma factors can include the duration/severity of trauma experience and the perception that the trauma has ended. Post-trauma factors can include access to needed resources, social support, specific cognitive patterns, and physical activity. To date, several important risk factors have been found to impact the risk of developing PTSD including gender, age, education, IQ, race and ethnicity, sexual orientation, pre-trauma psychopathology, prior trauma exposure, familial psychiatric history, and neurobiological factors. This article outlines the state of research findings on pretraumatic, peritraumatic, and posttraumatic risk factors for the development of PTSD and associated psychopathology following trauma.

    2014-09-01

    Since the U.S. Food and Drug Administration approved ractopamine hydrochloride and zilpaterol hydrochloride in animal feeds, usage of those compounds has been a topic of worldwide debate. Ractopamine and zilpaterol are β-adrenergic agonists used as veterinary drugs to increase weight gain in certain animals raised for food. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) established maximum residue limits for ractopamine, which were adopted by the Codex Alimentarius Commission (Codex). No maximum residue limits for zilpaterol have been adopted by JECFA, and new reports of animal mobility issues confront the use of this feed additive. However, many countries disagree with the Codex standards and are restricting or banning meat products containing β agonists. The bans by major importers of U.S. meat products have prompted some to advocate that the United States use the World Trade Organization dispute settlement body. This paper looks at the developments to provide a fuller accounting of what the issues may mean to U.S. firms selling meat products containing residues of β agonists. PMID:25057027

Ophthalmoscopic visualization of the fundus of traumatized eye can be obscured by corneal opacity, anterior chamber hyphema, cataractous change of the lens, or hemorrhage of the citreous. Ultrasound B-scan examination of the posterior pole is imperative in such cases to detect any intraocular damage and the presence of a foreign body. So we performed ultrasound B-scan examination of traumatized eye seventy eight patients and analyzed those findings. All cases were confirmed by follow up examination of ophthalmoscopy and ultrasound, or surgery. The results were as follows; 1. The most common cause of the ocular injury was traffic accidents (19 patients, 24.4%),male was more commonly injured (63 patients, 80.8). and the most common age group was their 4th decade. 2. Summary of sonographically detected intraocular lesions were as follows; 1) Corneal opacity (44 patients)-hyphema 15, traumatic cataract 24, vitreous hemorrhage 31, retinal detachment 20, intraocular foreign body 4, etc. 2) Hyphemal (16 patients)-hyphema 16, vitreous hemorrhage 11, tretinal detachment 5, etc. 3) Traumatic cataract with no corneal or lens opacity (6 patients)-vitreous hemorrhage with or without retinal detachment 3, normal vitreous and retina 3. 4) Vitreous opacity(12 patients)-vitreous hemorrhage 12, retinal detachment 4, intraocular foreign body 3, etc. In all seventy eight patients with ocular trauma , we could demonstrate characteristic findings for each intraocular lesion. So we recognized the important role and high diagnostic accuracy of ultrasound B-scan examination for the evaluation of the posterior pole of traumatized eye

    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

    Previous research has documented bidirectional relationships between trauma exposure and posttraumatic stress (PTS), such that individuals who are exposed to more traumatic events are at increased risk of developing PTS, and more severe PTS is associated with more subsequent trauma exposure. However, the empirical literature is limited by a lack of longitudinal studies that include continuous measures of PTS, differentiate between assaultive (e.g., sexual assault, being help up or mugged) and non-assaultive (e.g., serious illness, natural disaster) trauma, and focus on urban contexts. The purpose of this study was to fill these gaps through testing three-wave cross-lagged panel models of exposure to assaultive and non-assaultive traumatic events and PTS among a large sample of urban-dwelling adults (N = 1360; 84.4% non-Hispanic Black). In the model including assaultive trauma, more Wave 2 assaultive events were associated with significantly higher Wave 3 PTS. In contrast, in the model including non-assaultive trauma, higher Wave 1 and Wave 2 PTS were associated with more non-assaultive events at Waves 2 and 3, respectively. Taken together, the findings suggest a cycle of adversity wherein urban residents who have experienced assaultive trauma are at risk of more severe PTS, which in turn increases risk for exposure to non-assaultive trauma. This cycle could be tested directly in future studies through models including both types of events. Additional research on the mechanisms that underlie the pathways between PTS and traumatic events could also have implications for policy and practice. PMID:24886002

    Objectives To investigate the association between the time taken to make a decision to go to surgery and gender, ethnicity, years in profession, experience of trauma team training, experience of structured trauma courses and trauma in the trauma team, as well as use of closed-loop communication and leadership styles during trauma team training. Design In situ trauma team training. The patient simulator was preprogrammed to represent a severely injured patient (injury severity score: 25) suffering from hypovolemia due to external trauma. Setting An emergency room in an urban Scandinavian level one trauma centre. Participants A total of 96 participants were divided into 16 trauma teams. Each team consisted of six team members: one surgeon/emergency physician (designated team leader), one anaesthesiologist, one registered nurse anaesthetist, one registered nurse from the emergency department, one enrolled nurse from the emergency department and one enrolled nurse from the operating theatre. Primary outcome HRs with CIs (95% CI) for the time taken to make a decision to go to surgery was computed from a Cox proportional hazards model. Results Three variables remained significant in the final model. Closed-loop communication initiated by the team leader increased the chance of a decision to go to surgery (HR: 3.88; CI 1.02 to 14.69). Only 8 of the 16 teams made the decision to go to surgery within the timeframe of the trauma team training. Conversely, call-outs and closed-loop communication initiated by the team members significantly decreased the chance of a decision to go to surgery, (HR: 0.82; CI 0.71 to 0.96, and HR: 0.23; CI 0.08 to 0.71, respectively). Conclusions Closed-loop communication initiated by the leader appears to be beneficial for teamwork. In contrast, a high number of call-outs and closed-loop communication initiated by team members might lead to a communication overload. PMID:26826152

    The selective α1-adrenergic antagonist prazosin has been shown in multiple studies to be effective in targeting trauma-related nightmares in posttraumatic stress disorder. There are limited data regarding the effectiveness of another selective α1-adrenergic antagonist terazosin for the treatment of trauma-related nightmares. We present 4 cases in which terazosin was effectively used to treat nightmares as a second-line agent after prazosin failure. Further studies are needed to validate terazosin as an alternative to prazosin for the treatment of posttraumatic stress disorder-related nightmares. PMID:25970279

    2016-02-01

    The therapeutic potential of using dance/movement therapy is being increasingly recognized. Preliminary interdisciplinary research findings suggest engaging the body in trauma treatment might reduce the length of treatment by addressing the connections among thoughts, feelings, neurobiology, and somatic responses in the survivor. Unfortunately, empirical research investigating its effectiveness as a psychotherapeutic intervention has been limited due to the lack of a clear manual for mental health care practitioners. The present study aims to synthesize findings from the existing qualitative literature in a qualitative meta-synthesis. Our findings will contribute to the development of a body-oriented intervention for mental health care practitioners to use for trauma. PMID:26063604

    The GPCR relaxin family peptide receptor 1 (RXFP1) mediates the action of relaxin peptide hormone, including its tissue remodeling and antifibrotic effects. The peptide has a short half-life in plasma, limiting its therapeutic utility. However, small-molecule agonists of human RXFP1 can overcome this limitation and may provide a useful therapeutic approach, especially for chronic diseases such as heart failure and fibrosis. The first small-molecule agonists of RXFP1 were recently identified from a high-throughput screening, using a homogeneous cell-based cAMP assay. Optimization of the hit compounds resulted in a series of highly potent and RXFP1 selective agonists with low cytotoxicity, and excellent in vitro ADME and pharmacokinetic properties. Here, we undertook extensive site-directed mutagenesis studies in combination with computational modeling analysis to probe the molecular basis of the small-molecule binding to RXFP1. The results showed that the agonists bind to an allosteric site of RXFP1 in a manner that closely interacts with the seventh transmembrane domain (TM7) and the third extracellular loop (ECL3). Several residues were determined to play an important role in the agonist binding and receptor activation, including a hydrophobic region at TM7 consisting of W664, F668, and L670. The G659/T660 motif within ECL3 is crucial to the observed species selectivity of the agonists for RXFP1. The receptor binding and activation effects by the small molecule ML290 were compared with the cognate ligand, relaxin, providing valuable insights on the structural basis and molecular mechanism of receptor activation and selectivity for RXFP1.

    Drug self-administration methods were used to test the hypothesis that rats would self-medicate with a cannabinoid CB(2) agonist to attenuate a neuropathic pain state. Self-medication of the CB(2) agonist (R,S)-AM1241, but not vehicle, attenuated mechanical hypersensitivity produced by spared nerve injury. Switching rats from (R,S)-AM1241 to vehicle self-administration also decreased lever responding in an extinction paradigm. (R,S)-AM1241 self-administration did not alter paw withdrawal thresholds in sham-operated or naive animals. The percentage of active lever responding was similar in naive groups self-administering vehicle or (R,S)-AM1241. The CB(2) antagonist SR144528 blocked both antiallodynic effects of (R,S)-AM1241 self-medication and the percentage of active lever responding in neuropathic (but not naive) rats. Neuropathic and sham groups exhibited similar percentages of active lever responding for (R,S)-AM1241 on a fixed ratio 1 (FR1) schedule. However, neuropathic animals worked harder than shams to obtain (R,S)-AM1241 when the schedule of reinforcement was increased (to FR6). (R,S)-AM1241 self-medication on FR1, FR3, or FR6 schedules attenuated nerve injury-induced mechanical allodynia. (R,S)-AM1241 (900μg intravenously) failed to produce motor ataxia observed after administration of the mixed CB(1)/CB(2) agonist WIN55,212-2 (0.5mg/kg intravenously). Our results suggest that cannabinoid CB(2) agonists may be exploited to treat neuropathic pain with limited drug abuse liability and central nervous system side effects. These studies validate the use of drug self-administration methods for identifying nonpsychotropic analgesics possessing limited abuse potential. These methods offer potential to elucidate novel analgesics that suppress spontaneous neuropathic pain that is not measured by traditional assessments of evoked pain. PMID:21550725

    Full Text Available Abstract In England, trauma is the leading cause of death across all age groups, with over 16,000 deaths per year. Major trauma implies the presence of multiple, serious injuries that could result in death or serious disability. Successive reports have documented the fact that the current ad hoc unstructured management of this patient group is associated with considerable avoidable death and disability. The reform of trauma care in England, especially of the severely injured patient, has already begun. Strong clinical leadership is embraced as the way forward. The present article summarises the steps that have been made over the last decade that led to the recent decision to move towards a long anticipated restructure of the National Health Service (NHS trauma services with the introduction of Regional Trauma Networks (RTNs. While, for the first time, a genuine political will and support exists, the changes required to maintain the momentum for the implementation of the RTNs needs to be marshalled against arguments, myths and perceptions from the past. Such an approach may reverse the disinterest attitude of many, and will gradually evolve into a cultural shift of the public, clinicians and policymakers in the fullness of time.

    Injury in Australia was responsible for 400 000 hospitalisations in 2002. This study aimed to examine the direct costs of trauma patients in a Level 1 trauma centre and determine the compensability of those patients. Data on all admitted patients (206) filling trauma criteria were collected prospectively over a 3-month period (November 2006 to January 2007). A 10-question survey was completed on each patient to record mechanism of injury, third party private health insurance or workers compensation, and direct costs were also obtained. 30% of trauma admissions had an injury severity score (ISS)> 15 (n = 62; median ISS =9; range, 1-56). Median length of stay was 3 days (range, 1-126). Almost half (47%) of the patients were involved in road trauma, and 29% in falls. More than half (53.4%) were eligible for compensation (21.8% of patients had full hospital health insurance cover, 21.4% third party insurance and 9.2% workers compensation). The mechanism of injury with the highest median cost per patient was assault, followed by pedal cyclists, pedestrians then motor vehicle collisions. PMID:19203337

    Full Text Available The need of energy increases by 40% in patients with a head trauma, when compared to people who are living a normal life. This ratio reaches to 200% in some cases. It is important to give a nutrition support which can satisfy the energy need resulted from the hypermetabolic and hypercatabolic states and that is enough to help to fix the immunologic state and achieve a better result in healing the injury. When oral nutrition is not possible in the patient with a head trauma, their energy need is satisfied through enteral and parenteral nutrition. Though parenteral nutrition had held an important role in feeding patients with head trauma, enteral nutrition is applied much more widely today. Enteral and parenteral nutrition both has their own advantages and disadvantages. In the clinical and laboratory studies that had been held, it was found that enteral nutrition improved the systemic immunity, decreased the incidence of the major infectious complications, decreased the metabolic response to trauma, protected the intestinal mucosa, and protected the ecologic balance of the microflora. In this article, it is investigated through the importance of the feeding in patients with a head trauma and reasons to chose enteral nutrition

  19. Classification and management of chest trauma

    International Nuclear Information System (INIS)

    Objective: To classify the predominant pattern of injuries following blunt and penetrating chest trauma and to assess the adequacy of treatment strategies, complications and mortality associated with such injuries. Design: Descriptive study. Place and Duration of Study: Surgical Unit I, Holy Family Hospital, Rawalpindi, from December 2000 to December 2003. Patients and Methods: One hundred consecutive patients with thoracic trauma either blunt or penetrating, admitted in the ward were evaluated. Their injuries were classified, treatment strategies outlined and complications and mortality were documented on a specially-designed proforma. Results: Out of the 100 patients presenting in emergency, 44% presented with blunt and 56% with penetrating trauma. Pneumothorax was detected in 39% of the patients, hemopneumothorax in 29%, hemothorax in 12%, flail chest in 9%. Two had involvement of the heart and major vessels, 4% had injury to the diaphragm and 5% had multiple trauma. During treatment, 3% of all the patients were managed conservatively, 83% of patients required chest intubations, 6% needed ventilatory support and 8 % required thoracotomy. Complications were experienced in 28% of the patients of which 9% had pneumonias, 14% empyema and 5% suffered from wound infections. The overall mortality was 7%. Conclusion: This series showed the pattern of injuries following blunt and penetrating chest trauma. Furthermore, it was found that chest incubation and simple resuscitation was adequate for majority of the cases. (author)

    Full Text Available 【Abstract】Objective: To summarize the clinical features, diagnosis and treatment of chest trauma. Methods: A retrospective analysis was conducted among 336 cases of chest trauma admitted to our hospital from January 2009 to May 2011. Results: Out of all cases, 325 were cured, accounting for 96.7%; 11 died, accounting for 3.3%. Among the dead cases, one died of hemorrhagic shock, three of acute respi-ratory distress syndrome, three of multiple organ failure, and four of severe multiple traumas. Conclusions: (1 For patients with severe chest trauma, early emergency treatment is crucial to save life. (2 Open thoracic surgery is needed for acute cardiac tamponade, intrapulmonary vascular injuries, progressive intrathoracic bleeding, lung laceration, tracheal breakage, and diaphrag-matic injury. In addition, operative timing and method should be well chosen. (3 Pulmonary contusion is one of common complications in chest trauma, for which the com-bination of strong anti-infection therapy and mechanical ventilation is an effective treatment strategy.

    The incidence of chest trauma has increased significantly since the turn of the century especially in developed countries where rapid means of transportation has become part of daily life. Although gunshot wounds (GSWs) were the commonest causes of chest trauma in wartime, road traffic accidents (RTAs) have become the scourge of peacetime and modern civilization. Chest trauma is more common in males during the 2nd to the 5th decades of life with an average age of 40 years reducing their life expectancy by another 40 years at the most productive and active period of their lives. Despite improvement in ambulance service and rapid mobilization of victims from the scene of accident, about 10% of chest injured patients will die on the spot and another 5% die within an hour of reaching the hospital. Of the remaining 85%, five percent will require emergency thoracotomy for various reasons while 80% will respond to resuscitative measures and tube thoracostomy drainage alone. The primary aims in the management of chest trauma are prompt restoration of normal cardiorespiratory functions, control of haemorrhage, treatment of associated injuries and prevention of sepsis. Although the overall survival rate of trauma has improved in recent years, deaths are often due to airway obstruction, exsanguinating haemorrhage, flail chest, tension pneumothorax, cardiac tamponade and associated intracranial, intraabdominal and skeletal injuries.

    The morbidity, mortality, and economic costs resulting from trauma in general, and blunt abdominal trauma in particular, are substantial. The "panscan" (computed tomographic [CT] examination of the head, neck, chest, abdomen, and pelvis) has become an essential element in the early evaluation and decision-making algorithm for hemodynamically stable patients who sustained abdominal trauma. CT has virtually replaced diagnostic peritoneal lavage for the detection of important injuries. Over the past decade, substantial hardware and software developments in CT technology, especially the introduction and refinement of multidetector scanners, have expanded the versatility of CT for examination of the polytrauma patient in multiple facets: higher spatial resolution, faster image acquisition and reconstruction, and improved patient safety (optimization of radiation delivery methods). In this article, the authors review the elements of multidetector CT technique that are currently relevant for evaluating blunt abdominal trauma and describe the most important CT signs of trauma in the various organs. Because conservative nonsurgical therapy is preferred for all but the most severe injuries affecting the solid viscera, the authors emphasize the CT findings that are indications for direct therapeutic intervention.

    2012-01-01

    Full Text Available Persistent or chronic pain is prevalent in many developed countries, with estimates ranging from 10% to higher than 50%, and is a major economic burden to individuals and societies. However, the variation in pain outcomes after acute orthopedic trauma and treatment confronts treating physicians with uncertainty in providing prognostic advice regarding long-term recovery. Although several previous reviews have addressed the determinants of chronic pain outcomes secondary to acute trauma, they have primarily focused on specific injury samples and, furthermore, lack consistency with respect to the important prognostic factors, which limits the generalizability of findings. This review, however, aimed specifically to identify the early prognostic factors associated with variation in persistent pain outcomes following acute orthopedic trauma presenting with a spectrum of pathologies.

    This randomized waitlist control study examined the efficacy of Thought Field Therapy (TFT) in reducing Posttraumatic Stress Disorder symptoms in survivors of the 1994 genocide in Rwanda. Participants included 145 adult genocide survivors randomly assigned to an immediate TFT treatment group or a waitlist control group. Group differences adjusted for pretest scores and repeated measures anovas were statistically significant at p < .001 for 9 of 10 TSI trauma subscales and for both severity and frequency on the MPSS, with moderate to large effect sizes. Reduced trauma symptoms for the group receiving TFT were found for all scales. Reductions in trauma symptoms were sustained at a 2-year follow-up assessment. Limitations, clinical implications, and future research are discussed. PMID:22708146

    Full Text Available Abstract Background Trauma plays an important role in the experience of many patients with substance use disorder, but is relatively under-studied particularly in Australia. The present survey examined the lifetime prevalence of various forms of trauma including driving careers in the context of relevant medical conditions. Methods A survey was undertaken in a family medicine practice with a special interest in addiction medicine in Brisbane, Australia. Results Of 350 patients surveyed, 220 were substance dependent, and 130 were general medical patients. Addicted patients were younger (mean ± S.D. 33.72 ± 8.14 vs. 44.24 ± 16.91 years, P Conclusion This study shows that despite shorter driving histories, addicted patients have worse driving careers and general trauma experience than the comparison group which is not explained by associated medical conditions. Trauma is relevant to addiction management at both the patient and policy levels. Substance dependence policies which focus largely on prevention of virus transmission likely have too narrow a public health focus, and tend to engender an unrealistically simplistic and trivialized view of the addiction syndrome. Reduction of drug driving and drug related trauma likely require policies which reduce drug use per se, and are not limited to harm reduction measures alone.

  7. Is there a role for magnetic resonance imaging in renal trauma?

    International Nuclear Information System (INIS)

    Computed tomography (CT) has been the most informative imaging method in renal trauma. Despite the good sensitivity of magnetic resonance imaging (MRI) to the presence of hematoma, edema and ischemia, MRI has not been widely studied in patients with renal trauma. The present study was initiated to evaluate the role of MRI in patients with renal trauma. Between June 1998 and September 1999, CT and MRI were prospectively performed on 12 patients who suffered from renal trauma and the results reviewed. The presence and size of perirenal hematoma could be detected by both CT and MRI. Magnetic resonance imaging could differentiate intrarenal hematoma from perirenal hematoma more accurately, and provided additional information about the hematoma as T1- and T2-weighted MRI were able to determine recent bleeding in the hematoma by regional differences in signal intensity. Magnetic resonance imaging clearly revealed renal fracture with non-viable fragment and detected focal renal laceration that was not detected on CT due to perirenal hematoma associated with renal infarction. However, although MRI had many advantages over CT, it had also major drawbacks, which were that it required longer imaging time and increased the cost. Magnetic resonance imaging may be useful in renal trauma. However, it is suggested that MRI should be limited to carefully selected patients, such as those with severe renal injury or equivocal findings on CT. (author)

    2010-11-01

    Full Text Available Abstract Background In healing wounds, some monocytes enter the wound and differentiate into fibroblast-like cells called fibrocytes. Since Toll-like receptors (TLRs are present on monocytes, and pathogens that can infect a wound have and/or release TLR agonists, we examined whether TLR agonists affect fibrocyte differentiation. Results When human peripheral blood mononuclear cells (PBMCs were cultured with TLR3, TLR4, TLR5, TLR7, TLR8 or TLR9 agonists, there was no significant effect on fibrocyte differentiation, even though enhanced extracellular tumor necrosis factor (TNF-α accumulation and/or increased cell surface CD86 or major histocompatibility complex (MHC class II levels were observed. However, all TLR2 agonists tested inhibited fibrocyte differentiation without any significant effect on cell survival. Adding TLR2 agonists to purified monocytes had no effect on fibrocyte differentiation. However, some TLR2 agonists caused PBMCs to secrete a factor that inhibits the differentiation of purified monocytes into fibrocytes. This factor is not interferon (IFN-α, IFN-γ, interleukin (IL-12, aggregated immunoglobulin G (IgG or serum amyloid P (SAP, factors known to inhibit fibrocyte differentiation. TLR2 agonist-treated PBMCs secrete low levels of IL-6, TNF-α, IFN-γ, granulocyte colony-stimulating factor and tumor growth factor β1, but combinations of these factors had no effect on fibrocyte differentiation from purified monocytes. Conclusions Our results indicate that TLR2 agonists indirectly inhibit fibrocyte differentiation and that, for some TLR2 agonists, this inhibition involves other cell types in the PBMC population secreting an unknown factor that inhibits fibrocyte differentiation. Together, these data suggest that the presence of some bacterial signals can inhibit fibrocyte differentiation and may thus slow wound closure.

  9. Dopamine agonist withdrawal syndrome: implications for patient care.

    2013-08-01

    Dopamine agonists are effective treatments for a variety of indications, including Parkinson's disease and restless legs syndrome, but may have serious side effects, such as orthostatic hypotension, hallucinations, and impulse control disorders (including pathological gambling, compulsive eating, compulsive shopping/buying, and hypersexuality). The most effective way to alleviate these side effects is to taper or discontinue dopamine agonist therapy. A subset of patients who taper a dopamine agonist, however, develop dopamine agonist withdrawal syndrome (DAWS), which has been defined as a severe, stereotyped cluster of physical and psychological symptoms that correlate with dopamine agonist withdrawal in a dose-dependent manner, cause clinically significant distress or social/occupational dysfunction, are refractory to levodopa and other dopaminergic medications, and cannot be accounted for by other clinical factors. The symptoms of DAWS include anxiety, panic attacks, dysphoria, depression, agitation, irritability, suicidal ideation, fatigue, orthostatic hypotension, nausea, vomiting, diaphoresis, generalized pain, and drug cravings. The severity and prognosis of DAWS is highly variable. While some patients have transient symptoms and make a full recovery, others have a protracted withdrawal syndrome lasting for months to years, and therefore may be unwilling or unable to discontinue DA therapy. Impulse control disorders appear to be a major risk factor for DAWS, and are present in virtually all affected patients. Thus, patients who are unable to discontinue dopamine agonist therapy may experience chronic impulse control disorders. At the current time, there are no known effective treatments for DAWS. For this reason, providers are urged to use dopamine agonists judiciously, warn patients about the risks of DAWS prior to the initiation of dopamine agonist therapy, and follow patients closely for withdrawal symptoms during dopamine agonist taper.

    Full Text Available Traditionally, the exploration of the impact of trauma on trauma survivors in South Africa has been focused mainly on the bio-psychosocial aspects. The bio-psychosocial approach recognises that trauma affects people biologically, socially and psychologically. In this article, the author explores a holistic understanding of the effects of trauma on people from communities historically affected by political violence in KwaZulu-Natal, South Africa. Using a participatory action research design (PAR as a way of working through trauma, a longitudinal study was conducted in Pietermaritzburg from 2009–2013. At the end of the study, life narratives were documented and published. The textual analysis of these life narratives reveals that, besides the bio-psychosocial effects that research participants experienced during and after the trauma, they also sustained moral and spiritual injuries. Trauma took its toll in their lives emotionally, psychologically, spiritually, morally and in their relationships with themselves, others and God. From these findings, the author argues that the bio-psychosocial approach is incomplete for understanding the holistic effects of trauma on the whole person. Therefore, he recommends the integration of the moral and spiritual aspects of trauma to come up with a holistic model of understanding the effects of trauma on traumatised individuals. The holistic model will enhance the treatment, healing and recovery of trauma survivors. This, in turn, will alleviate the severe disruption of many aspects of psychological functioning and well-being of trauma survivors caused by the effects of trauma.

    Tissue injury results in the release of the intracellular protein actin which is cleared from the circulation by the plasma proteins gelsolin and Gc-globulin, constituting the Extracellular Actin Scavenger System (EASS). Experimental studies have shown that excessive amounts of actin in the...... circulation can lead to a condition resembling multiple organ dysfunction syndrome (MODS), and we have previously demonstrated that the level of Gc-globulin is decreased after severe trauma. The purpose of the present study was to determine whether the plasma levels of gelsolin were altered in the early phase...... after trauma. Twenty-three consecutive trauma patients were studied. Plasma samples were assayed for gelsolin by immunonephelometry with polyclonal rabbit antihuman gelsolin prepared in our own laboratory. The median time from injury until the time the first blood sample was taken was 52 min (range 20...

  12. Leukotrienes as mediators in tissue trauma

    International Nuclear Information System (INIS)

    A significant increase in the production of cysteinyl leukotrienes was observed after mechanical or thermal trauma in the anesthesized rat. The amount of biliary N-acetyl-leukotriene E4, which represents a suitable indicator for blood plasma leukotrienes, was used as a measure of leukotriene generation. Cysteinyl leukotrienes were rapidly eliminated from blood plasma into bile where N-acetyl-leukotriene E4 was the major metabolite. Leukotrienes were at a much lower concentration in blood plasma than in bile and differed in the pattern of metabolites. The detected amounts of leukotrienes were sufficient to induce known phenomena associated with trauma, such as tissue edema and circulatory and respiratory dysfunction. Increased leukotriene generation appears to play an important role in the pathophysiology of tissue trauma

    Mesenteric trauma, i.e., injuries located in the bowel or organs supplied by the superior mesenteric artery, can be life-threatening. The incidence of these lesions is low. Most occur as result of blunt and penetrating abdominal trauma due mainly to gunshot wounds or road accidents. Management of these serious injuries can be challenging in the military field hospitals. The major problem in austere environment is the unavailabiity of computerized axial and other tools gene rally used for diagnosis. As an alternative to tomography diagnostic peritoneal lavage can be used with a high sensitivity for the detection of mesenteric trauma. The second difficulty is technical. General surgeons without vasular training or supplies must prepared to suspect and reonstuct lesions of the superior mesenteric available resources. PMID:16775948

    Full Text Available AIM Role of 3 Dimensional Computed Tomography in facial fractures. METHODS AND MATERIALS 133 patients with history of head trauma were scanned using multi slice CT for a period of 2 yrs. Data acquisition was performed using - 16 Slice GE Bright Speed Elite CT Scanner. The datasets were transferred to workstation and VR post-processing protocols were applied. RESULTS 122 patients were male and 11 were female. The mean age of patients with fractures was 32.3 years old. Fractures included the mandible, the maxilla, the frontal bone, the zygomatic arch and the nasal bone. CONCLUSION Continuing advances in computer software algorithms and improved precision in the acquisition of radiographic data makes 3D reformatted CT imaging a necessary complement to traditional 2D CT imaging in the management of complex facial trauma. CT is the investigation of choice in the evaluation of patients with maxillofacial trauma.

  15. Trauma radiology in infancy and childhood

    International Nuclear Information System (INIS)

    The aim of this review article is to familiarise the reader with the specific paediatric conditions in trauma radiology. The article briefly describes the major pathophysiologic differences in childhood and the consecutive altered injury pattern. The standard radiological imaging protocol for various involved body regions and different trauma settings/varying queries is described, with suggestion for standardised diagnostic flowcharts in some typical settings. Special regard is given to radiation protection and the potential of newer imaging modalities such as ultrasound, multi-detector- and spiral CT as well as MRI in paediatric trauma patients. As such the paper hopefully provides some basic guidelines for general radiologists in peripheral hospitals who less often have to deal with paediatric queries. (orig.)

    Abdominal trauma is a common cause of death particularly in patients up to 40 years of age. In order to reduce mortality a rapid radiologic diagnosis is essential. At present, sonography plays a role only in the evaluation of minor trauma and as a 'focused assessment with sonography for trauma' (FAST) to clarify free intraperitoneal fluid immediately on admittance in severely injured patients. However, computed tomography has proven to be a potent tool for the triage of patients with abdominal trauma, because, based on the results of the CT scan, patients can be referred for laparotomy or safely classified for 'wait and see' treatment. Therapeutic decisions are largely based on injury severity scores and the radiologist must be familiar with them as well as with the associated therapeutic consequences. (orig.) [German] Das Trauma des Abdomens ist insbesondere bei Patienten unter 40 Jahren eine haeufige Todesursache. Die rasche Erstellung aussagekraeftiger radiologischer Befunde ist unerlaesslich, um die Mortalitaet zu senken. Die Sonographie wird heute nur mehr bei Bagatelltraumen und als 'focused assessment with sonography for trauma' (FAST) zur Abklaerung freier intraperitonealer Fluessigkeit unmittelbar nach dem Eintreffen schwer verletzter Patienten verwendet. Hingegen hat die Radiologie mit der Multidetektorcomputertomographie (MDCT) ein geeignetes Instrument zur Verfuegung, um seine Rolle fuer die Triage zur operativen oder konservativen Behandlung von Patienten nach Trauma des Abdomens erfuellen zu koennen. Die therapeutischen Entscheidungen werden wesentlich von Verletzungsscores bestimmt, mit denen der Radiologe zusammen mit den sich daraus ergebenden Konsequenzen vertraut sein muss. (orig.)

    Full Text Available Abstract Background Insulin resistance is often associated with increased levels of intracellular triglycerides, diacylglycerol and decreased fat β-oxidation. It was unknown if this relationship was present in patients with acute insulin resistance induced by trauma. Methods A double blind placebo controlled trial was conducted in 18 children with severe burn injury. Metabolic studies to assess whole body palmitate oxidation and insulin sensitivity, muscle biopsies for mitochondrial palmitate oxidation, diacylglycerol, fatty acyl Co-A and fatty acyl carnitine concentrations, and magnetic resonance spectroscopy for muscle and liver triglycerides were compared before and after two weeks of placebo or PPAR-α agonist treatment. Results Insulin sensitivity and basal whole body palmitate oxidation as measured with an isotope tracer increased significantly (P = 0.003 and P = 0.004, respectively after PPAR-α agonist treatment compared to placebo. Mitochondrial palmitate oxidation rates in muscle samples increased significantly after PPAR-α treatment (P = 0.002. However, the concentrations of muscle triglyceride, diacylglycerol, fatty acyl CoA, fatty acyl carnitine, and liver triglycerides did not change with either treatment. PKC-θ activation during hyper-insulinemia decreased significantly following PPAR-α treatment. Conclusion PPAR-α agonist treatment increases palmitate oxidation and decreases PKC activity along with reduced insulin sensitivity in acute trauma, However, a direct link between these responses cannot be attributed to alterations in intracellular lipid concentrations.

    Full Text Available Background: Elder abuse and neglect (EAN, intimate partner violence (IPV, and street-based community violence (SBCV are significant public health problems, which frequently lead to traumatic injury. Trauma centers can provide an effective setting for intervention and referral, potentially interrupting the cycle of violence. Aims: To assess existing institutional resources for the identification and treatment of violence victims among patients presenting with acute injury to statewide trauma centers. Settings and Design: We used a prospective, web-based survey of trauma medical directors at 62 Illinois trauma centers. Nonresponders were contacted via telephone to complete the survey. Materials and Methods: This survey was based on a survey conducted in 2004 assessing trauma centers and IPV resources. We modified this survey to collect data on IPV, EAN, and SBCV. Statistical Analysis: Univariate and bivariate statistics were performed using STATA statistical software. Results: We found that 100% of trauma centers now screen for IPV, an improvement from 2004 (P = 0.007. Screening for EAN (70% and SBCV (61% was less common (P < 0.001, and hospitals thought that resources for SBCV in particular were inadequate (P < 0.001 and fewer resources were available for these patients (P = 0.02. However, there was lack of uniformity of screening, tracking, and referral practices for victims of violence throughout the state. Conclusion: The multiplicity of strategies for tracking and referring victims of violence in Illinois makes it difficult to assess screening and tracking or form generalized policy recommendations. This presents an opportunity to improve care delivered to victims of violence by standardizing care and referral protocols.

    The first Malaysian National Trauma Database was launched in May 2006 with five tertiary referral centres to determine the fundamental data on major trauma, subsequently to evaluate the major trauma management and to come up with guidelines for improved trauma care. A prospective study, using standardized and validated questionnaires, was carried out from May 2006 till April 2007 for all cases admitted and referred to the participating hospitals. During the one year period, 123,916 trauma patients were registered, of which 933 (0.75%) were classified as major trauma. Patients with blunt injury made up for 83.9% of cases and RTA accounted for 72.6% of injuries with 64.9% involving motorcyclist and pillion rider. 42.8% had severe head injury with an admission Glasgow Coma Scale (GCS) of 3-8 and the Revised Trauma Score (RTS) of 5-6 were recorded in 28.8% of patients. The distribution of Injury Severity Score (ISS) showed that 42.9% of cases were in the range of 16-24. Only 1.9% and 6.3% of the patients were reviewed by the Emergency Physician and Surgeon respectively. Patients with admission systolic blood pressure of less than 90 mmHg had a death rate of 54.6%. Patients with severe head injury (GCS report has successfully demonstrated its significance in giving essential data on major trauma in Malaysia, however further expansion of the study may reflect more comprehensive trauma database in this country.

    Objective: Injuries are common and important problem in Tehran, capital of Iran. Although therapeutic centers are not essentially established following the constructional principles of developed countries, the present opportunities and equipments have to be used properly. We should recognize and reduce the deficits based on the global standards.This study deliberates the trauma resources and capacities in university hospitals of Tehran based on Arizona trauma center standards, which are suitable for the assessment of trauma centers.Methods: Forty-one university hospitals in Tehran were evaluated for their conformity with "Arizona trauma center standards" in 2008. A structured interview was arranged with the "Educational Supervisor" of all hospitals regarding their institutional organization, departments, clini-cal capabilities, clinical qualifications, facilities and resources, rehabilitation services, performance improvement, continuing education, prevention, research and additional requirements for pediatric trauma patients. Relative frequencies and percentages were calculated and Student's t test was used to compare the mean values.Results: Forty-one hospitals had the average of 77.7 (50.7%) standards from 153 Arizona trauma center standards and these standards were present in 97.5 out of 153 (63.7%) in 17 general hospitals. Based on the subgroups of the standards, 64.8% items of hospital resources and capabilities were considered as a subgroup with the maximum criteria, and 17.7% items of research section as another subgroup with the minimum standards.Conclusions: On the basis of our findings, no hospital meet all the Arizona trauma center standards completely. The hospitals as trauma centers at different levels must be promoted to manage trauma patients desirably.

    Background Trauma remains a leading cause of death worldwide. The development of trauma systems in low-resource settings may be of benefit. The objective of this study was to describe operative procedures performed for trauma at a tertiary care facility in Kigali, Rwanda, and to evaluate geographical variations and referral patterns of trauma care. Methods We retrospectively reviewed all prospectively collected operative cases performed at the largest referral hospital in Rwanda, the Centre Hospitalier Universitaire de Kigali (CHUK), between June 1 and Dec. 1, 2011, for injury-related diagnoses. We used the Pearson χ2 and Fisher exact tests to compare cases arising from within Kigali to those transferred from other provinces. Geospatial analyses were also performed to further elucidate transfer patterns. Results Over the 6-month study period, 2758 surgical interventions were performed at the CHUK. Of these, 653 (23.7%) were for trauma. Most patients resided outside of Kigali city, with 337 (58.0%) patients transferred from other provinces and 244 (42.0%) from within Kigali. Most trauma procedures were orthopedic (489 [84.2%]), although general surgery procedures represented a higher proportion of trauma surgeries in patients from other provinces than in patients from within Kigali (28 of 337 [8.3%] v. 10 of 244 [4.1%]). Conclusion To our knowledge, this is the first study to highlight geographical variations in access to trauma care in a low-income country and the first description of trauma procedures at a referral centre in Rwanda. Future efforts should focus on maturing prehospital and interfacility transport systems, strengthening district hospitals and further supporting referral institutions. PMID:26812407

    Blunt thoracic aortic injury (BTAI) remains a common cause of death following blunt mechanisms of trauma. Among patients who survive to reach hospital care, significant advances in diagnosis and treatment afford previously unattainable survival. The Society for Vascular Surgery (SVS) guidelines provide current best-evidence suggestions for treatment of BTAI. However, several key areas of controversy regarding optimal BTAI care remain. These include the refinement of selection criteria, timing for treatment and the need for long-term follow-up data. In addition, the advent of the Aortic Trauma Foundation (ATF) represents an important development in collaborative research in this field. PMID:25868973

  7. Importance of multidetector CT imaging in multiple trauma

    International Nuclear Information System (INIS)

    Diagnostic imaging of complex multiple trauma remains a challenge for any department providing modern emergency radiology (ER) service. An early and comprehensive approach for ER imaging is crucial for a priority-oriented and timely therapy concept with the aim of identifying potentially life-threatening injuries early and initiating appropriate treatment. The basic diagnostic approach still consists of focused ultrasound using focused assessment with sonography for trauma (FAST) and conventional radiography (CR), usually limited to a single supine chest x-ray for triaging patients undergoing immediate operations. Multidetector computed tomography (MDCT) has become established as early whole body CT (WBCT) as the undisputable diagnostic method. The detection rate of injuries by WBCT is outstanding and it improves the probability of survival by 20-25 % compared with all other previous methods. At the same time, the spatial and temporal resolution of MDCT was improved resulting in considerably shortened examination times but WBCT is still associated with a significant radiation exposure, even in the acute single use setting. Using modern scanner and dose reduction technology, including iterative reconstruction, a dose reduction of up to 40 % could be achieved. The substantial number of images in WBCT is another challenge; images must be processed priority-oriented, read and transferred to the picture archiving and communications system (PACS). For rapid diagnosis, volume image reading (VIR) offers additional options to keep the diagnostic process on time. Modern WBCT after multiple trauma is performed early, comprehensively and personalized so that WBCT improves the probability of survival by 20-25 %. (orig.)

    To examine the degree of trauma in major osteoporotic fractures (MOF) in men versus women, we used data from 15,698 adults aged ≥65 years enrolled in the Osteoporotic Fractures in Men (MrOS) study (5994 men) and the Study of Osteoporotic Fractures (SOF) (9704 women). Participants were contacted tri-annually to ascertain incident fractures, which were confirmed by radiographic reports and coded according to degree of self-reported trauma. Trauma was classified as low (fall from ≤ standing height; fall on stairs, steps, or curb; minimal trauma other than fall [coughing, turning over]); moderate (collisions with objects during normal activity without associated fall); or high (fall from > standing height; severe trauma [motor vehicle accident, assault]). MOF included hip, clinical vertebral, wrist, and humerus fractures. Mean fracture follow-up was 9.1 years in SOF and 8.7 years in MrOS. A total of 14.6% of the MOF in men versus 6.3% of the MOF in women were classified as high trauma (p standing height. High-trauma fractures were more significantly common in men versus women at the hip (p = 0.002) and wrist (p < 0.001) but not at the spine or humerus. Among participants with MOF, the odds ratio of a fracture related to high-trauma fracture among men versus women was 3.12 (95% confidence interval [CI] 1.70-5.71) after adjustment for traditional risk factors. Findings were similar in analyses limited to participants with hip fractures (odds ratio [OR] = 3.34, 95% CI 1.04-10.67) and those with wrist fracture (OR = 5.68, 95% CI 2.03-15.85). Among community-dwelling older adults, MOF are more likely to be related to high trauma in men than in women. These findings are not explained by sex differences in conventional risk factors and may reflect a greater propensity among men to engage in risky behavior. © 2015 American Society for Bone and Mineral Research.

    Pathological gambling (PG), classified in the DSM-IV among impulse control disorders, is defined as inappropriate, persistent gaming for money with serious personal, family, and social consequences. Offenses are frequently committed to obtain money for gambling. Pathological gambling, a planned and structured behavioral disorder, has often been described as a complication of dopamine agonist treatment in patients with Parkinson's disease. It has never been described in patients with schizophrenia receiving dopamine agonists. We present two patients with schizophrenia, previously treated with antipsychotic drugs without any suggestion of PG, who a short time after starting aripiprazole, a dopamine partial agonist, developed PG and criminal behavior, which totally resolved when aripiprazole was discontinued. Based on recent advances in research on PG and adverse drug reactions to dopamine agonists in Parkinson's disease, we postulate a link between aripiprazole and PG in both our patients with schizophrenia and raise the question of criminal responsibility.

    Full Text Available The compounds 1-(2,6-diethylphenylimidazolidine-2-thione and 2-(2,6-diethylphenylimidazolidine showed the almost same activity as octopamine in stimulating adenylate cyclase of cockroach thoracic nervous system among 70 octopamine agonists, suggesting that only these compounds are full octopamine agonists and other compounds are partial octopamine agonists. The quantitative structure-activity relationship of a set of 22 octopamine agonists against receptor 2 in cockroach nervous tissue, was analyzed using receptor surface modeling. Three-dimensional energetics descriptors were calculated from receptor surface model/ligand interaction and these three-dimensional descriptors were used in quantitative structure-activity relationship analysis. A receptor surface model was generated using some subset of the most active structures and the results provided useful information in the characterization and differentiation of octopaminergic receptor.

    The antidepressants currently used need improvement, especially in terms of efficacy, relapse rate and onset of action. In this review the clinical and experimental data which support the rationale for 5-HT2C agonists in the treatment of depression are listed. Next, the results obtained with the non-selective 5-HT2C agonists on the market and in clinical development are described. Finally, the preclinical data on the more selective 5-HT2C agonists are summarized. These recent preclinical results reveal a greater potency and effect size compared to fluoxetine, good tolerability and no evidence of tolerance development. Selective 5-HT2C agonists might become innovative drugs for the treatment of depression, panic, obsessive-compulsive disorder (OCD), some forms of aggression and eating disorders. PMID:16160946

    Human motor control has constraints in terms of its responsiveness, which limit its ability to successfully perform tasks. In a previous study, it was shown that the ability to balance an upright stick became progressively more challenging as the natural frequency (angular velocity without control) of the stick increased. Furthermore, forearm and trunk agonist and antagonist muscle activation increased as the natural frequency of the stick increased, providing evidence that the central nervous system produces agonist-antagonist muscle activation to match task dynamics. In the present study, visual feedback of the stick position was influenced by changing where subject focused on the stick during stick balancing. It was hypothesized that a lower focal height would degrade motor control (more uncertainty in tracking stick position), thus making balancing more challenging. The probability of successfully balancing the stick at four different focal heights was determined along with the average angular velocity of the stick. Electromyographic signals from forearm and trunk muscles were also recorded. As expected, the probability of successfully balancing the stick decreased and the average angular velocity of the stick increased as subjects focused lower on the stick. In addition, changes in the level of agonist and antagonist muscle activation in the forearm and trunk was linearly related to changes in the angular velocity of the stick during balancing. One possible explanation for this is that the central nervous system increases muscle activation to account for less precise motor control, possibly to improve the responsiveness of human motor control.

    Glioblastomas (GBM), deadly brain tumors, have greater incidence in males than females. Epidemiological evidence supports a tumor suppressive role of estrogen; however, estrogen as a potential therapy for GBM is limited due to safety concerns. Since GBM express ERβ, a second receptor for estrogen, targeting ERβ with a selective agonist may be a potential novel GBM therapy. In the present study, we examined the therapeutic effect of the selective synthetic ERβ agonist LY500307 using in vitro and in vivo GBM models. Treatment with LY500307 significantly reduced the proliferation of GBM cells with no activity on normal astrocytes in vitro. ERβ agonists promoted apoptosis of GBM cells, and mechanistic studies using RNA sequencing revealed that LY500307 modulated several pathways related to apoptosis, cell cycle, and DNA damage response. Further, LY500307 sensitized GBM cells to several FDA-approved chemotherapeutic drugs including cisplatin, lomustine and temozolomide. LY500307 treatment significantly reduced the in vivo tumor growth and promoted apoptosis of GBM tumors in an orthotopic model and improved the overall survival of tumor-bearing mice in the GL26 syngeneic glioma model. Our results demonstrate that LY500307 has potential as a therapeutic agent for GBM. PMID:27126081

    Ehlert, Frederick J.; Suga, Hinako; Griffin, Michael T.

    2011-01-01

    When an agonist activates a population of G protein-coupled receptors (GPCRs), it elicits a signaling pathway that culminates in the response of the cell or tissue. This process can be analyzed at the level of a single receptor, a population of receptors, or a downstream response. Here we describe how to analyze the downstream response to obtain an estimate of the agonist affinity constant for the active state of single receptors.

    Establishing post-traumatic stress disorder as a psychiatric diagnosis has only marginally increased awareness of traumatic experiences. Traumas are inconsistently recorded in initial psychiatric histories and, when observed, rarely reflected in the primary diagnosis and treatment. The present study aimed to investigate if there is an association between sufficiently addressing trauma and long-term outcome and what factors affect whether trauma, according to the patient's view, is sufficiently addressed or not. Socio-demographic data, experiences of trauma and treatment, and outcome, were collected retrospectively from Arabic, Iranian, Turkish and Swedish patients, who had visited a psychiatric clinic 3-4 years earlier. Fifty-one patients whose traumatic experiences had been sufficiently addressed were compared with 39 patients who perceived that their traumas had not been addressed. Logistic regression analyses were performed to examine relationships between clinical variables and whether or not traumas had been addressed. Patients with trauma sufficiently addressed reported high confidence in staff (odds ratio, OR=7.2, pSwede (OR=2.4, p<0.10) were the background variables independently related to having trauma sufficiently addressed. Addressing trauma may improve patients' confidence in staff, self-rated health and trauma-related symptoms. Multiplicity of traumas and belonging to an ethnic minority implied that trauma was less addressed. PMID:15370780

    Current antitussive medications have limited efficacy and often contain the opiate-like agent dextromethorphan (DEX). The mechanism whereby DEX inhibits cough is ill defined. DEX displays affinity at both NMDA and sigma receptors, suggesting that the antitussive activity may involve central or peripheral activity at either of these receptors. This study examined and compared the antitussive activity of DEX and various putative sigma receptor agonists in the guinea-pig citric-acid cough model. Intraperitoneal (i.p.) administration of DEX (30 mg kg−1) and the sigma-1 agonists SKF-10,047 (1–5 mg kg−1), Pre-084 (5 mg kg−1), and carbetapentane (1–5 mg kg−1) inhibited citric-acid-induced cough in guinea-pigs. Intraperitoneal administration of a sigma-1 antagonist, BD 1047 (1–5 mg kg−1), reversed the inhibition of cough elicited by SKF-10,047. In addition, two structurally dissimilar sigma agonists SKF-10,047 (1 mg ml−1) and Pre-084 (1 mg ml−1) inhibited cough when administered by aerosol. Aerosolized BD 1047 (1 mg ml−1, 30 min) prevented the antitussive action of SKF-10,047 (5 mg kg−1) or DEX (30 mg kg−1) given by i.p. administration and, likewise, i.p. administration of BD 1047 (5 mg kg−1) prevented the antitussive action of SKF-10,047 given by aerosol (1 mg ml−1). These results therefore support the argument that antitussive effects of DEX may be mediated via sigma receptors, since both systemic and aerosol administration of sigma-1 receptor agonists inhibit citric-acid-induced cough in guinea-pigs. While significant systemic exposure is possible with aerosol administration, the very low doses administered (estimated <0.3 mg kg−1) suggest that there may be a peripheral component to the antitussive effect.

    Opioids are the most effective and widely used drugs for pain treatment. Morphine is an archetypal opioid and is an opioid receptor agonist. Unfortunately, the clinical usefulness of morphine is limited by adverse effects such as analgesic tolerance and addiction. Therefore, it is important to study the development of novel opioid agonists as part of pain control. The analgesic effects of opioids are mediated by three opioid receptors, namely opioid μ-, δ-, and κ-receptors. They belong to the G protein-coupled receptor superfamily and are coupled to Gi proteins. In the present study, we developed a ligand screening system to identify novel opioid μ-receptor agonists that measures [(35)S]GTPγS binding to cell membrane fractions prepared from the fat body of transgenic silkworms expressing μ-receptor-Gi1α fusion protein. We screened the RIKEN Natural Products Depository (NPDepo) chemical library, which contains 5848 compounds, and analogs of hit compounds. We successfully identified a novel, structurally unique compound, that we named GUM1, with agonist activity for the opioid μ-receptor (EC50 of 1.2 µM). The Plantar Test (Hargreaves' Method) demonstrated that subcutaneous injection of 3mg/kg of GUM1 into wild-type rats significantly extended latency time. This extension was also observed in a rat model of morphine tolerance and was inhibited by pre-treatment of naloxone. The unique molecular skeleton of GUM1 makes it an attractive molecule for further ligand-opioid receptor binding studies. PMID:26476280

  5. Should We Use PPAR Agonists to Reduce Cardiovascular Risk?

    Directory of Open Access Journals (Sweden)

    Jennifer G. Robinson

    2008-01-01

    Full Text Available Trials of peroxisome proliferator-activated receptor (PPAR agonists have shown mixed results for cardiovascular prevention. Fibrates are PPAR- agonists that act primarily to improve dyslipidemia. Based on low- and high-density lipoprotein cholesterol (LDL and HDL effects, gemfibrozil may be of greater cardiovascular benefit than expected, fenofibrate performed about as expected, and bezafibrate performed worse than expected. Increases in both cardiovascular and noncardiovascular serious adverse events have been observed with some fibrates. Thiazolidinediones (TZDs are PPAR- agonists used to improve impaired glucose metabolism but also influence lipids. Pioglitazone reduces atherosclerotic events in diabetic subjects, but has no net cardiovascular benefit due to increased congestive heart failure risk. Rosiglitazone may increase the risk of atherosclerotic events, and has a net harmful effect on the cardiovascular system when congestive heart failure is included. The primary benefit of TZDs appears to be the prevention of diabetic microvascular complications. Dual PPAR-/ agonists have had unacceptable adverse effects but more selective agents are in development. PPAR- and pan-agonists are also in development. It will be imperative to prove that future PPAR agonists not only prevent atherosclerotic events but also result in a net reduction on total cardiovascular events without significant noncardiovascular adverse effects with long-term use.

  6. Considering trauma exposure in the context of genetics studies of posttraumatic stress disorder: a systematic review

    Science.gov (United States)

    2013-01-01

    Background Posttraumatic stress disorder (PTSD) is a debilitating anxiety disorder. Surveys of the general population suggest that while 50-85% of Americans will experience a traumatic event in their lifetime, only 2-50% will develop PTSD. Why some individuals develop PTSD following trauma exposure while others remain resilient is a central question in the field of trauma research. For more than half a century, the role of genetic influences on PTSD has been considered as a potential vulnerability factor. However, despite the exponential growth of molecular genetic studies over the past decade, limited progress has been made in identifying true genetic variants for PTSD. Methods In an attempt to aid future genome wide association studies (GWAS), this paper presents a systematic review of 28 genetic association studies of PTSD. Inclusion criteria required that 1) all participants were exposed to Criterion A traumatic events, 2) polymorphisms of relevant genes were genotyped and assessed in relation to participants’ PTSD status, 3) quantitative methods were used, and 4) articles were published in English and in peer-reviewed journals. In the examination of these 28 studies, particular attention was given to variables related to trauma exposure (e.g. number of traumas, type of trauma). Results Results indicated that most articles did not report on the GxE interaction in the context of PTSD or present data on the main effects of E despite having data available. Furthermore, some studies that did consider the GxE interaction had significant findings, underscoring the importance of examining how genotypes can modify the effect of trauma on PTSD. Additionally, results indicated that only a small number of genes continue to be studied and that there were marked differences in methodologies across studies, which subsequently limited robust conclusions. Conclusions As trauma exposure is a necessary condition for the PTSD diagnosis, this paper identifies gaps in the current

    Abdominal trauma is a leading cause of death in children older than 1 year of age. The spleen is the most common organ injured following blunt abdominal trauma. Pediatric trauma patients present unique clinical challenges as compared to adults, including different mechanisms of injury, physiologic responses, and indications for operative versus nonoperative management. Splenic salvage techniques and nonoperative approaches are preferred to splenectomy in order to decrease perioperative risks, transfusion needs, duration/cost of hospitalization, and risk of overwhelming postsplenectomy infection. Early and accurate detection of splenic injury is critical in both adults and children; however, while imaging findings guide management in adults, hemodynamic stability is the primary determinant in pediatric patients. After initial diagnosis, the primary role of imaging in pediatric patients is to determine the level and duration of care. We present a comprehensive literature review regarding the mechanism of injury, imaging, management, and complications of traumatic splenic injury in pediatric patients. Multiple patients are presented with an emphasis on the American Association for the Surgery of Trauma organ injury grading system. Clinical practice guidelines from the American Pediatric Surgical Association are discussed and compared with our experience at a large community hospital, with recommendations for future practice guidelines.

    International Nuclear Information System (INIS)

    While trauma is still the leading cause of death in the pediatric age range, it is surprising how little the CT appearances of pediatric chest injury have been investigated in the literature. We have reviewed the CT findings of blunt chest trauma in 44 children for whom chest CT examinations were requested to investigate the extent of intrathoracic injury. We noted a propensity for pulmonary contusions to be located posteriorly or posteromedially, and for them to be anatomically nonsegmental and crescentic in shape. This is possibly attributable to the relatively compliant anterior chest wall in children. The CT appearances of other major thoracic injuries are described, including pulmonary lacerations, pneumothoraces, malpositioned chest tubes, mediastinal hematomas, aortic injury, tracheobronchial injury, hemopericardium, and spinal injuries with paraspinal fluid collections. Children demonstrating findings incidental to the actual injury yet important to the subsequent therapy are also presented. We conclude that, in the event of clinically significant blunt chest trauma, the single supine chest examination in the trauma room is insufficient to adequately identify the extent of intrathoracic injury. With the exception of concern for aortic injury for which aortography is indicated, a dynamically enhanced CT scan of the thorax should be performed as clinically significant findings may result in altered therapy.

  17. Trauma as a shibboleth in psychoanalysis?

    Science.gov (United States)

    Sacerdoti, G; Semi, A A

    1989-01-01

    The authors consider that the subject of trauma is a good example of how metapsychological constructs (in this case, in particular, the economic or quantitative point of view) originated as essential working hypotheses necessitated by clinical observation. These conceptualizations may help us to understand what finds expression in processes that are sensed as affects (als Affekte der Empfindung bemerkbar werden) either by the patient or by the analyst. In the case of trauma (in analysis), an object-relations approach is not only compatible (Balint) with metapsychology but seems to be positively implicit in a correct interpretation of the latter. Two clinical vignettes are given as evidence for this assumption. They illustrate an irruption of stimuli through the protective shield (Reizschutz) of the analytic field, initiated by the patient and the analyst respectively. For the purpose of grasping and working through such situations--thus helping the patient to fill the gap (Ablösung) between the quota of affect (Affektbetrag) and the idea (Vorstellung)--it is very useful for the analyst to refer to the concept of trauma, either in the narrow or in the broad sense proposed by Freud. For this reason, the authors believe that the concept of trauma is a shibboleth of psychoanalysis. PMID:2737835

    Full Text Available The treatment of children presenting dental trauma in the primary dentition requires a different approach from that used in the permanent dentition, because there is a very close relation between the apex of the traumatized primary tooth and the successor permanent bud. The possible consequences on the permanent teeth should be considered when performing early treatment in order to prevent further damage. Also, the probable trauma’s late sequelae should be taken into account both for primary and permanent dentition. Given the subject’s importance, this chapter aimed to report this issue broadly. This comprises the anamnesis, general, intraoral, and radiographic examination and the comprehensive treatment of the patient. Additionally to the classification of dental injuries, we highlighted the diagnosis, required treatment,prognosis, and follow-up of each clinical situation. A topic on soft tissue lesion was included, because it has a great impact on both the child and family. Moreover, it could be associated with other trauma types. Since the analysis of the child’s vaccination status is suggested, in face of cases demanding that tetanus vaccine be valid, the recommendation of the Brazilian Ministry of Health was also informed. Furthermore, there is an item on dental splinting, parenting advice, and trauma consequences on primary and successor permanent teeth. At the end of the chapter, two tables summarize the early and delayed treatment of trauma involving primary tooth’s enamel, dentin, pulp, and supportive tissues.
