Is amoxicillin/clavulanic acid sufficient for preemptive antibiotic therapy in type III grade open fractures ?

The risk of infection after type III° open fractures is high (10-50%).Preemptive antibiotic therapy may prevent posttraumatic infection andimprove the outcome. Recommendations about the type and durationof antibiotic vary among the institutions and it remains unclear whethergram-negative bacilli or anaerobs need to be covered. In Europe, themost commonly recommended antibiotic is amoxicillin/clavulanic acid.We retrospectively analyzed microbiology, characteristics and outcomeof patients with open type III° fractures treated at our institution.Methods: Between 01/2005 and 12/2009 we retrospectively includedall type III grade open fractures of the leg at our institution classifiedafter Gustilo into type IIIA, IIIB and IIIC. Demographic characteristics,clinical presentation, microbiology, surgical and antibiotic treatmentand patient outcome were recorded using a standardized case-reportform.Results: 30 cases of patients with type III° open fractures wereincluded (25 males, mean age was 40.5 years, range 17-67 years).27 fractures (90%) were located on the lower leg and 3 (10%) on theupper leg. Microbiology at initial surgery was available for 19 cases(63%), of which 10 grew at least one organism (including 8 amoxicillin/clavulanic acid-resistant gram-negative bacilli [GNB], 7 amoxicillin/clavulanic acid-resistant Bacillus cereus), 11 were culture-negative.Preemptive antibiotics were given in all cases (100%) for an averageduration of 8.5 days (range 1-53 days), the most common antibioticwas amoxicillin/clavulanic acid in 60% (n = 18). 11 cases just receivedpreemptive antibiotic treatment, in 19 of 30 cases the antibiotic therapywas changed and prolonged. Microbiology at revision surgery wasavailable for 25 cases and 22 grew at least one pathogen (including32 amoxicillin/clavulanic acid-resistant gram-negative bacilli and 10amoxicillin/clavulanic acid-resistant Bacillus cereus), 3 were culturenegative.Conclusions: At initial surgery, most common isolated organismswere coagulase-negative staphylococci (43%), Bacillus cereus (23%),and gram-negative bacilli (27%), and others (7%) of which 48% wereresistant to amoxicillin/clavulanic acid. At revision surgery, isolatedorganisms were gram-negative bacilli (64%), Bacillus cereus (20%),and others (16%) of which 88% were resistant to amoxicillin/clavulanicacid. The spectrum of amoxicillin/clavulanic does not cover the mostcommon isolated organisms.FM32

Daptomycin plus fosfomycin versus daptomycin monotherapy in treating MRSA: protocol of a multicentre, randomised, phase III trial.

INTRODUCTION Despite the availability of new antibiotics such as daptomycin, methicillin-resistant Staphylococcus aureus (MRSA) bacteraemia continues to be associated with high clinical failure rates. Combination therapy has been proposed as an alternative to improve outcomes but there is a lack of clinical studies. The study aims to demonstrate that combination of daptomycin plus fosfomycin achieves higher clinical success rates in the treatment of MRSA bacteraemia than daptomycin alone. METHODS AND ANALYSIS A multicentre open-label, randomised phase III study. Adult patients hospitalised with MRSA bacteraemia will be randomly assigned (1:1) to group 1: daptomycin 10 mg/kg/24 h intravenous; or group 2: daptomycin 10 mg/kg/24 h intravenous plus fosfomycin 2 gr/6 g intravenous. The main outcome will be treatment response at week 6 after stopping therapy (test-of-cure (TOC) visit). This is a composite variable with two values: Treatment success: resolution of clinical signs and symptoms (clinical success) and negative blood cultures (microbiological success) at the TOC visit. Treatment failure: if any of the following conditions apply: (1) lack of clinical improvement at 72 h or more after starting therapy; (2) persistent bacteraemia (positive blood cultures on day 7); (3) therapy is discontinued early due to adverse effects or for some other reason based on clinical judgement; (4) relapse of MRSA bacteraemia before the TOC visit; (5) death for any reason before the TOC visit. Assuming a 60% cure rate with daptomycin and a 20% difference in cure rates between the two groups, 103 patients will be needed for each group (α:0.05, ß: 0.2). Statistical analysis will be based on intention to treat, as well as per protocol and safety analysis. ETHICS AND DISSEMINATION The protocol was approved by the Spanish Medicines and Healthcare Products Regulatory Agency (AEMPS). The sponsor commits itself to publishing the data in first quartile peer-review journals within 12 months of the completion of the study. TRIAL REGISTRATION NUMBER NCT01898338.

The Franco-German motor before the eastern enlargement: the causes of its decline

The Franco-German axis has been a transcendent force behind the European integration ever since the early years of the EEC. Nevertheless, since the fall of the Berlin Wall in November 1989, the perception of a progressive distancing between France and Germany as far as the EU politics is concerned, has increased. There has not been a definitive break in Franco-German relations. However, the influence of the Franco-German axis in the EU has been reduced in the 90s. Finally, in the Nice IGC (December 2000), the misunderstandings of these two “big” states about their weight in the Council, almost caused the failure to conclude the Treaty of Nice, clearing the way for the Eastern enlargement. The traditional balance between France and Germany has been eroded. Germany has consolidated its role of leadership in the EU, and above all towards the candidate countries. The purpose of this paper is to analyse the fifth enlargement as one of the causes of the decline of the Franco-German axis as the motor of the process of European integration.

Cuestiones controvertidas en evaluación económica (III). Intervenciones sanitarias en tres situaciones especiales: enfermedades raras, tratamientos al final de la vida y externalidades en las evaluaciones.

The development of the economic evaluation of health care interventions has become a support tool in making decisions on pricing and reimbursement of new health interventions. The increasingly extensive application of these techniques has led to the identification of particular situations in which, for various reasons, it may be reasonable to take into account special considerations when applying the general principles of economic evaluation. In this article, which closes a series of three, we will discuss, using the Metaplan technique, about the economic evaluation of health interventions in special situations such as rare diseases and end of life treatments, as well as consideration of externalities in assessments, finally pointing out some research areas to solve the main problems identified in these fields.

Adaptation en français et en allemand d'une échelle de pression des pairs pour jeunes adultes : le Peer Pressure Inventory [Adaptation of a peer pressure scale in French and German: the Peer Pressure Inventory].

BACKGROUND: Peer pressure is regarded as an important determinant of substance use, sexual behavior and juvenile delinquency. However, few peer pressure scales are validated, especially in French or German. Little is known about the factor structure of such scales or the kind of scale needed: some scales takes into account both peer pressure to do and peer pressure not to do, while others consider only peer pressure to do. The aim of the present study was to adapt French and German versions of the Peer Pressure Inventory, which is one of the most widely used scales in this field. We considered its factor structure and concurrent validity. METHODS: Five thousand eight hundred and sixty-seven young Swiss men filled in a questionnaire on peer pressure, substance use, and other variables (conformity, involvement) in a cohort study. RESULTS: We identified a four-factor structure, with the three factors of the initial Peer Pressure Inventory (involvement, conformity, misconduct) and adding a new one (relationship with girls). A non-valued scale (from no peer pressure to peer pressure to do only) showed stronger psychometric qualities than a valued scale (from peer pressure not to do to peer pressure to do). Concurrent validity was also good. Each behavior or attitude was significantly associated with peer pressure. CONCLUSION: Peer pressure seems to be a multidimensional concept. In this study, peer pressure to do showed the strongest influence on participants. Indeed, peer pressure not to do did not add anything useful. Only peer pressure to do affected young Swiss men's behaviors and attitudes and was reliable.

Comparison of neoadjuvant cisplatin-based chemotherapy versus radiochemotherapy followed by resection for stage III (N2) NSCLC

Résumé : Objectif: Analyse d'un traitement de chimiothérapie à base de cisplatine de type néoadjuvant en comparaison à un traitement de radio-chimiothérapie suivi de la résection chirurgicale chez des patients présentant un carcinome pulmonaire non à petites cellules de stade Ill (N2) prouvé histologiquement par médiastinoscopie. Evaluation de la morbidité postopératoire, du down-staging ganglionnaire, des taux de survie globale et sans récidive ainsi que du site de récidive. Matériel et méthodes : 82 patients ont été inclus dans l'étude entre Janvier 1994 et Juin 2003, parmi eux 36 ont été traités avec une chimiothérapie néoadjuvante à base de cisplatine et doxétacel (groupe l). Les autres 46 patients ont été soumis à une radio-chimiothérapie néoadjuvante avec administration de 44 Gy (groupe II), soit de façon séquentielle (25 cas) soit concomitante (21 cas). Dans tous les cas des métastases à distance ont été exclues par une évaluation préopératoire comprenant une scintigraphie osseuse, un Ct scan thoraco-abdominal, ou un examen PET scan ainsi qu'une IRM cérébrale. La médiastinoscopie effectuée avant le traitement d'induction chez la totalité des patients, de même que la résection chirurgicale de la tumeur pulmonaire et la lymphadenectomie médiastinale ont été effectuées par le même chirurgien. Résultats : La tumeur pulmonaire était de stade Ti à T2 dans respectivement 47% et 28% des patients des groupes (e II, T3 dans 45% et 41% et T4 dans 8% et 31% des cas. Le type de résection effectué (lobectomie, lobectomie en manchon, pneumonectomie) était comparable dans les deux collectifs (p=0.03) Le taux de mortalité postopératoire à 90 jours était de respectivement 3% et 4 "Vo (p=0.6). Une résection complète (RO) a pu être obtenue dans 92% et 94% des cas (p=0.6) avec un downstaging ganglionnaire médiastinal dans 61% et 78% des patients respectivement (p<0.001). Les taux de survie globale à 5 ans et de survie sans récidive à 5 ans s'élevaient à 40% et à 36% respectivement, sans différence significative entre des tumeurs de stade Ti à T3 et T4. Le taux de survie globale n'était pas significativement différent entre les deux modalités de traitement d'induction, toutefois après radio-chimiothérapie on observait une plus longue survie sans récidive (p.0.04). Il n'y avait par ailleurs pas de différence significative, en termes de morbidité post-opératoire, résecabilité, downstaging ganglionnaire, survie globale et sans récidive, entre les patients traités par radio-chimiothérapie séquentielle ou concomitante. Conclusions : En cas de carcinome pulmonaire non à petites cellules de stade III (N2) un traitement d'induction par radio chimiothérapie suivi de la résection chirurgicale est associé avec un meilleur downstaqing médiastinal ainsi qu'une plus longue survie sans récidive en comparaison au traitement d'induction par chimiothérapie seule. Abstract : Objective: Comparison of prospectively treated patients with neoadjuvant cisplatin-based chemotherapy vs radiochemotherapy followed by resection for mediastinoscopically proven stage III NZ non-small cell lung cancer with respect to postoperative morbidity, pathological nodal downstaging, overall and disease-free survival, and site of recurrence. Methods: Eighty-two patients were enrolled between January 1994 to June 2003, 36 had cisplatin and doxetacel-based chemotherapy (group I) and 46 cisplatin-based radiochemotherapy up to 44 Gy (group II), either as sequential (25 patients) or concomitant (21 patients) treatment. All patients had evaluation of absence of distant metastases by bone scintigraphy, thoracoabdominal CT scan or PET scan, and brain MRI, and all underwent pre-induction mediastinoscopy, resection and mediastinal lymph node dissection by the same surgeon. Results: Group I and II comprised T1/2 tumors in 47 and 28%, 13 tumors in 45 and 41%, and 14 tumors in 8 and 31% of the patients, respectively (P=0.03). There was a similar distribution of the extent of resection (lobectomy, sleeve lobectomy, left and right pneumonectomy) in both groups (P=0.9). Group I and II revealed a postoperative 90-d mortality of 3 and 4% (P=0.6), a RO-resection rate of 92 and 94% (P=0.9), and a pathological mediastinal downstaging in 61 and 78% of the patients (P<0.01), respectively. 5y-overall survival and disease-free survival of all patients were 40 and 36%, respectively, without significant difference between T1-3 and T4 tumors. There was no significant difference in overall survival rate in either induction regimens, however, radiochemotherapy was associated with a longer disease-free survival than chemotherapy (P=0.04). There was no significant difference between concurrent vs sequential radiochemotherapy with respect to postoperative morbidity, resectability, pathological nodal downstaging, survival and disease-free survival. Conclusions: Neoadjuvant cisplatin-based radiochemotherapy was associated with a similar postoperative mortality, an increased pathological nodal downstaging and a better disease-free survival as compared to cisplatin doxetacel-based chemotherapy in patients with stage III (N2) NSCLC although a higher number of 14 tumors were admitted to radiochemotherapy.

Prescribing practices in German and Swiss psychiatric university and in non-university hospitals : national differences

RÉSUMÉ Il existe dans la pratique de prescription des médicaments de grandes variations entre les hôpitaux. Ces variations sont d'origines multifactorielles, comme par exemple des traditions de prescriptions locales, des considérations pharmato-économiques, la disponibilité d'un médicament, des différences de population, la prévalence d'une maladie, etc. Les études disponibles sur les pratiques de prescription sont souvent réduites à un centre unique, à une région ou à un pays. L'emploi de méthodes et de définitions particulières a jusqu'à pressent limité des comparaisons plus étendues entre les pays et régions. Le but de cette étude est de comparer la pratique de prescription de nouveaux médicaments psychotropes dans des cliniques suisses et allemandes. Cinq hôpitaux psychiatriques ont été sélectionnés, faisant tous partie du projet AMSP, et représentant des cliniques suisses, allemandes, de niveau universitaire ou non. Des données sur 572 patients et 1745 prescriptions ont été collectées durant un jour précis. Les comparaisons ont été ajustées pour l'âge et le sexe. Une différence significative (p <0.001) a été trouvée dans la prescription de nouveaux médicaments antidépresseurs, les cliniciens suisses en donnant en moyenne plus (65.2%) que les allemands (48.3%). Aucune différence significative n'a été démontrée dans la prescription des nouveaux médicaments antipsychotiques atypiques. Il semble en conséquence que les psychiatres suisses ont une propension plus élevée à prescrire des nouveaux médicaments antidépresseurs. Cela semble être dû à des différences de traditions de prescriptions nationales ou régionales. D'autres études sont nécessaires pour investiguer les influences économiques sur la pratique de prescription dans des cliniques suisses et allemandes. SUMMARY Obiective: There are great variations between hospitals in the way drugs are prescribed and these variations may be due to multiple factors such as local prescribing traditions, pharmacoeconomic considerations, drug availability; regional differences of population, disease prevalence etc. Available studies on prescribing habits have, besides studies performed in a unique centre, until now often been restricted to single countries or regions and the comparisons across countries or regions have often been limited by the use of diverse methodologies and definitions. The aim of the present study was to compare drug prescriptions between German and Swiss psychiatric services with regard to their preference of newer psychotropics. Material, method: Five psychiatric hospitals, associated to the AMSP-project, were chosen to represent Swiss and German clinics, university and non-university settings. Data were available from one index day on 572 patients and 1745 prescriptions. The comparisons were adjusted for age and gender. Results: There was a significant difference (p < 0.001) with regard to the prescription of newer antidepressants (NAD), Swiss clinicians giving proportionally more (65.2 %) than the German psychiatrists (48.3 %). No significant difference was, on the other hand, found as to the proportion of atypical antipsychotics, the lack of difference being due to the higher proportion of clozapine among the atypical antipsychotics in Germany. Conclusion: There seems therefore to be a higher propensity for Swiss hospital psychiatrists to prescribe newer antidepressants. This seems to be due to national or regional prescribing traditions. Further studies are needed to investigate the economical influences on antidepressant prescribing in Swiss and German clinics.)
