Management of bleeding following major trauma: a European guideline

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

La bérylliose chronique, une pathologie sous-diagnostiquée: état des lieux en Suisse

Introduction.- La bérylliose chronique est une granulomatose pulmonaire pour laquelle le diagnostic est rarement posé en raison d'une méconnaissance du risque d'exposition professionnelle au béryllium.En outre, le tableau clinique, les signes radiologiques et les symptômes ressemblent a` une sarcoïdose. Ainsi, la fréquence de la maladie est probablement sous-estimée malgré l'utilisation de béryllium dans la fabrication de nombreux produits industriels et techniques en Suisse, tels que ressorts, prothèses dentaires, micro-électronique... Comme aide au diagnostic, un test de prolifération lymphocytaire au béryllium (BeLPT) a été développé pour évaluer la réponse immunocellulaire spécifique au béryllium. Mais celui-ci présente des inconvénients : utilisation de produits radioactifs, variabilité interlaboratoire importante, valeur prédictive contesteé. L'utilisation de l'Elispot, évaluant également la réponse lymphocytaire pourrait être une alternative au BeLPT. Objectifs.- Les objectifs de l'étude sont, d'une part, de déceler parmi les cas de sarcoïdose du registre SIOLD (Swiss Group for Interstitial and Orphan Lung Diseases) des cas de bérylliose sous-diagnostiqués et, d'autre part, d'améliorer les tests de de´pistage (questionnaire et test immunologique) de sensibilisation et de diagnostic. Méthode.- Cent soixante autoquestionnaires évaluant l'exposition professionnelle au béryllium ont été adressés à des patients référencés dans le registre SIOLD, souffrant de sarcoïdose. Les patients relatant dans l'autoquestionnaire un contact professionnel avec le béryllium ont bénéficié d'une visite médicale à l'Institut universitaire romand de santé au travail (IST) comportant une anamnèse professionnelle, un questionnaire spécifique à l'exposition au béryllium (questionnaire de Cherry) et une prise de sang. Par la suite, le sang a été analysé par Elispot pour évaluer la possibilité d'une sensibilisation au béryllium. En parallèle, des patients déjà diagnostiqués pour une bérylliose par un BeLPT ont servi de cas contrôle positifs pour la mise en place du test. Résultats.- Cinquante pour cents des autoquestionnaires adressés aux patients du registre SIOLD ont été renvoyés. Parmi ceux-ci, 33 %(26 personnes) rapportaient une exposition professionnelle possible au béryllium et ont été reçus a` l'IST pour compléter l'anamnèse professionnelle et répondre au questionnaire adapté de Cherry. Il ressort de ce questionnaire que 3 personnes ont effectivement travaillé avec du béryllium au cours de leur carrière professionnelle et que 4 ont potentiellement été exposées dans le contexte de leur environnement professionnel. Tous les patients ont été testés par Elispot, mais aucun n'a montré de prolifération évoquant une sensibilisation au béryllium. Des résultats supplémentaires devraient être disponibles dès février. Conclusion.- Au vu de ces résultats où seules 7 personnes sur les 80 ayant répondu au questionnaire (8 %) sont suspectées d'avoir été exposées directement ou indirectement au béryllium au cours de leur activité professionnelle, il est possible que le risque d'exposition au béryllium soit anecdotique, malgré une utilisation importante de ce métal dans certaines régions de Suisse. Une hypothèse envisageable est que la population de l'étude ne soit pas représentative de la population exposée. En outre, le fait que les tests lymphocytaires effectués sur les 7 personnes ayant rapporté une exposition au béryllium soient revenus négatifs peut être expliqué de 2 manières : soit que chez ces personnes, la maladie pulmonaire n'est pas due au béryllium, même si l'anamnèse professionnelle est positive et qu'il s'agit bien d'une sarcoïdose, soit que la prise de corticoïdes modifie la réponse immunitaire, soit que le test n'est pas suffisamment sensible.

A new rating scale to evaluate the potential benefit of therapeutic drug monitoring

Aims: Therapeutic Drug Monitoring (TDM) is an established tool to optimize thepharmacotherapy with immunosupressants, antibiotics, antiretroviral agents, anticonvulsantsand psychotropic drugs. The TDM expert group of the Association ofNeuropsychopharmacolgy and Pharmacopsychiatry recommended clinical guidelinesfor TDM of psychotropic drugs in 2004 and in 2011. They allocate 4 levelsof recommendation based on studies reporting plasma concentrations and clinicaloutcomes. To evaluate the additional benefit for drugs without direct evidence forTDM and to verify the recommendation levels of the expert group the authorsbuilt a new rating scale. Methods: This rating scale included 28 items and wasdivided in 5 categories: Efficacy, toxicity, pharmacokinetics, patient characteristicsand cost effectiveness. A literature search was performed for 10 antidepressants,10 antipsychotics, 8 drugs used in the treatment of substance related disordersand lithium, thereafter, a comparison with the assessment of the TDMexpert group was carried out. Results: The antidepressants as well as the antipsychoticsshowed a high and significant correlation with the recommendations inthe consensus guidelines. However, meanderings could be detected for the drugsused in the therapy of substance related disorders, for which TDM is mostly notestablished yet. The result of the antidepressants and antipsychotics permits aclassification of the reachable points; upper 13 - TDM strongly recommended10 to 13 - TDM recommended, 8 to 10 - TDM useful and below 8 - TDMpotentially useful. Conclusion: These results suggest this rating scale is sensitiveto detect the appropriateness of TDM for drug treatment. For those drugs TDM isnot established a more objective estimation is possible, thus the scoring helps tofocus on the most likely drugs to require TDM.

Diversity of sandflies (Psychodidae: Phlebotominae) captured in sandstone caves from Central Amazonia, Brazil

In the present paper we describe the diversity of phlebotomine sandflies collected in three sandstone caves in the municipality of Presidente Figueiredo, state of Amazonas, Brazil. The phlebotomines were captured during 2006 with CDC light traps. Guano samples from inside the Gruta Refúgio do Maruaga were collected to investigate the presence of immature specimens. A total of 2,160 adult phlebotomines representing 15 species were captured. Pintomyia pacae was the dominant species in Gruta dos Animais (1,723 specimens) and Gruta dos Lages (50 specimens) and Deanemyia maruaga new comb (280 specimens) was the dominant species in Gruta Refúgio do Maruaga. A total of 18 guano samples were collected and seven of these samples included immature specimens. A total of 507 immature specimens were captured; 495 of these specimens were larvae and 12 were pupae. The presence of paca (Agouti paca) footprints near Gruta dos Animais and Gruta dos Lages suggests the association of Pi. pacae with this rodent. This finding may explain the abundance of Pi. pacae in these locations, while the species is relatively rare in the forest. Deanemyia maruaga is a cave species that uses guano to breed during its immature stages. Adult specimens of this species are apparently parthenogenetic and autogenous and represent the second record of parthenogenesis for the subfamily Phlebotominae.

Bodyweight and migration-related differences in motor abilities in preschool children "Ballabeina"

Introduction: Motor abilities in schoolchildren have been decreasing in the last two decades (Bös, 2003, Tomkinson et al., 2003). This may be related to the dramatic increase in overweight and adiposity during the same time period. Children of migrant background are especially affected (Lasserre et al., 2007). But little is known about the relationship between BMI and migration background and motor abilities in preschool children. Methods/Design We carried out a cross-sectional analysis with 665 children (age 5.1 ± 0.6 years; 49.8 % female) of 40 randomly selected kindergarten classes from German and French speaking regions in Switzerland with a high migrant background. We investigated BMI, cardiorespiratory fitness (20 m shuttle run), static (displacement of center of pressure (COP)) and dynamic (balancing forward on a beam) postural control and overall fitness (obstacle course). Results: Of the children, 9.6 % were overweight, 10.5 % were obese (Swiss national percentiles) and 72.8 % were of migrant background (at least one parent born outside of Switzerland). Mean BMI from children of non-migrant background was 15.5 ± 1.1 kg/m2, while migrant children had a mean BMI of 15.8 ± 1.7 kg/m2 (p=0.08). Normal-weight children performed better in cardiorespiratory fitness (3.1 ± 1.4 vs. 2.6 ± 1.1 stages, p<0.001), overall fitness (18.9 ± 4.4 vs. 20.8 ± 4.6 sec, p<0.001) and in dynamic balance (4.9 ± 3.5 vs. 3.8 ± 2.5 steps, p<0.001) compared to overweight and obese children, while the latter had less postural sway (COP: 956 ± 302 vs. 1021 ± 212 mm, p=0.008). There was a clear inverse dose-response relationship between weight status and dynamic motor abilities. There were no significant differences in most tested motor abilities between non-migrant and migrant. The latter performed less well in only one motor test (overall fitness: 20.2 ± 5.2 vs. 18.3 ± 3.5 sec, p<0.001). These findings persisted after adjustment for BMI. Conclusion In preschool children, differences in motor abilities are already present between normal weight and overweight/obese children. However, migrant children demonstrate similar motor abilities compared to non-migrant children for almost all tests, despite their slightly higher BMI.

Management of bleeding and coagulopathy following major trauma: an updated European guideline.

INTRODUCTION: Evidence-based recommendations are needed to guide the acute management of the bleeding trauma patient. When these recommendations are implemented patient outcomes may be improved. METHODS: The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing a guideline for the management of bleeding following severe injury. This document represents an updated version of the guideline published by the group in 2007 and updated in 2010. Recommendations were formulated using a nominal group process, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) hierarchy of evidence and based on a systematic review of published literature. RESULTS: Key changes encompassed in this version of the guideline include new recommendations on the appropriate use of vasopressors and inotropic agents, and reflect an awareness of the growing number of patients in the population at large treated with antiplatelet agents and/or oral anticoagulants. The current guideline also includes recommendations and a discussion of thromboprophylactic strategies for all patients following traumatic injury. The most significant addition is a new section that discusses the need for every institution to develop, implement and adhere to an evidence-based clinical protocol to manage traumatically injured patients. The remaining recommendations have been re-evaluated and graded based on literature published since the last edition of the guideline. Consideration was also given to changes in clinical practice that have taken place during this time period as a result of both new evidence and changes in the general availability of relevant agents and technologies. CONCLUSIONS: A comprehensive, multidisciplinary approach to trauma care and mechanisms with which to ensure that established protocols are consistently implemented will ensure a uniform and high standard of care across Europe and beyond.

The STOP the Bleeding Campaign.

According to the World Health Organization, traumatic injuries worldwide are responsible for over 5 million deaths annually. Post-traumatic bleeding caused by traumatic injury-associated coagulopathy is the leading cause of potentially preventable death among trauma patients. Despite these facts, awareness of this problem is insufficient and treatment options are often unclear. The STOP the Bleeding Campaign therefore aims to increase awareness of the phenomenon of post-traumatic coagulopathy and its appropriate management by publishing European guidelines for the management of the bleeding trauma patient, by promoting and monitoring the implementation of these guidelines and by preparing promotional and educational material, organising activities and developing health quality management tools. The campaign aims to reduce the number of patients who die within 24 hours after arrival in the hospital due to exsanguination by a minimum of 20% within the next 5 years.
