Revised definitions of invasive fungal disease from the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group.

BACKGROUND: Invasive fungal diseases are important causes of morbidity and mortality. Clarity and uniformity in defining these infections are important factors in improving the quality of clinical studies. A standard set of definitions strengthens the consistency and reproducibility of such studies. METHODS: After the introduction of the original European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group definitions, advances in diagnostic technology and the recognition of areas in need of improvement led to a revision of this document. The revision process started with a meeting of participants in 2003, to decide on the process and to draft the proposal. This was followed by several rounds of consultation until a final draft was approved in 2005. This was made available for 6 months to allow public comment, and then the manuscript was prepared and approved. RESULTS: The revised definitions retain the original classifications of "proven," "probable," and "possible" invasive fungal disease, but the definition of "probable" has been expanded, whereas the scope of the category "possible" has been diminished. The category of proven invasive fungal disease can apply to any patient, regardless of whether the patient is immunocompromised, whereas the probable and possible categories are proposed for immunocompromised patients only. CONCLUSIONS: These revised definitions of invasive fungal disease are intended to advance clinical and epidemiological research and may serve as a useful model for defining other infections in high-risk patients.

Particularités de la prise en charge des infections chez le patient neutropénique [Special feature in the handling of infectious in neutropenic patients]

Les progrès continus des connaissances réalisés dans le domaine de l'oncohématologie depuis quelques décennies ont permis une amélioration considérable du pronostic de la plupart des formes de cancer. Toutefois, la morbidité et la mortalité attribuables aux infections apparaissent actuellement comme les principaux facteurs limitant l'agressivité des traitements de la maladie cancéreuse, et un meilleur contrôle de ces dernières est devenu l'un des éléments essentiels de la prise en charge de ce type de patients. Une recherche clinique intense a permis d'en identifier les grands principes qui sont exposés dans cet article. Un algorithme thérapeutique susceptible de guider le clinicien face au développement d'un état fébrile, toujours suspect d'infection chez le patient cancéreux neutropénique, est ensuite proposé.

Functional significance of first metatarso-phalangeal joint arthrodesis : FM101

Introduction: Indications for arthrodesis of the first metatarsophalangeal joint (MTP1) are commonly arthrosis (hallux rigidus), rheumatoid arthritis, failed hallux valgus surgery, severe hallux valgus, infectious arthritis, fractures and neuroarthropathies. Many reports focus on technical and radiological issues but few studies emphasize the functional outcome considering daily activities, sports and expectation of the patient. Method: We retrospectively reviewed the patients who underwent MTP1-arthrodesis from 2002 to 2005 in our institution. Clinical and radiological results were assessed but we specially focussed on the functional outcome. Scoring systems used were the SF-12, EQ-5D, PASI, FFI and AOFAS (10 points given to MTP1 mobility) scales. Results: 61 of 64 consecutive patients were evaluated. Female to male ratio was 49:15, mean age at surgery was 67 years, the average follow up was 29 month. Even if radiological consolidation was incomplete in 18 patients, all patients had a clinically stable and rigid arthrodesis. Mean AOFAS score was 87 (24-100) points at follow up. The FFI was 5.91% (0-66%). Patient satisfaction was excellent in 37 patients (60%), good in 18 (30%), fair in 5(8%) and poor in1 (2%). EQ- 5D was 0.7 (0.4-1).40 patients (66%) estimated their cosmetic result as excellent, 15 (25%) as good, 4(6%) as fair and 2 (3%)as poor. 10 patients (16%) had no shoe wear limitation , 48 (79%) had to wear comfortable shoes and 3 (5%) needed orthopaedic wearing. Professionally 34 patients (56%) had better performances, 18 (26%) had no change and 9 (18%) had aggravation of their capacities but this was due to other health reasons. In sports, 16 patients (26%) had better performances, 35 patients (57%) no change and 10 (17%) were worse as consequence of other health problems for 7. Finally, 56 patients (92%) would recommend the operation and 5 (8%) would not. Conclusion: Experience of clinical practice suggests that the idea of fusing the first MTP joint is initially frequently disregarded by the patients because they fear to be limited by a rigid forefoot. Our results show, in fact, that this procedure can be proposed for numerous pathological situations with the perspective of good to excellent outcome in terms of function and quality of life in the majority of cases.

Swiss behavioural surveillance system 1986-2008

Background: Second generation surveillance is a central feature of HIV/AIDS policy in Switzerland. Behavioural surveys in the general population, men having sex with men (MSM) and injecting drug users (IDU) have been regularly conducted since the early nineties. After peaking at 2144 cases in 1991, the number of new HIV cases notified to the Ministry of Health decreased in each subpopulation until 2000 (n=578) and then rose again to 735 in 2006. The recent increase is mainly due to MSM. Methods: In the general population, representative cross-sectional telephone surveys have been conducted 11 times since 1987. Surveys in convenience samples of MSM, recruited through gay newspapers and gay organisations, have been conducted 5 times since 1992. Surveys among IDU's attending needle exchange programmes have been conducted 5 times since 1993. Condom statistics, available since 1986, are included in the behavioural surveillance system. Results: In the general population aged 17-30, systematic condom use with casual partners in the last six months increased from 8.0% in 1987 to 75.8% in 2007. The proportion of MSM reporting anal intercourse with casual partners in the last 12 months increased from 61% in 1992 to 79% in 2007 (lowest value 56% in 1994) and unprotected anal intercourse with these partners increased from 14 % in 1992 to 24% in 2007 (lowest value 9% in 1994). The proportion of IDUs reporting borrowing used injection equipment decreased from 16.5% in 1993 to 8.9% in 2006. The ratio condoms released to retail/population aged 15-65 increased from 1.68 in 1986 to 3.8 in 2006. Conclusions: It has been possible to maintain a coherent behavioural surveillance system on a long-term basis, allowing for the monitoring of HIV prevention policy outcome and forseeing the development and distribution of new HIV cases in the population.

Isokinetic rotator muscles fatigue in glenohumeral joint instability before and after Latarjet surgery: a pilot prospective study.

We aimed to analyze the changes in isokinetic internal (IR) and external (ER) rotator muscles fatigue (a) in patients with non-operated recurrent anterior instability, and (b) before and after shoulder surgical stabilization with the Bristow-Latarjet procedure. Thirty-seven patients with non-operated unilateral recurrent anterior post-traumatic instability (NG) were compared with 12 healthy subjects [control group (CG)]. Twenty patients with operated recurrent anterior instability group (OG) underwent isokinetic evaluation before and 3, 6, and 21 months after Bristow-Latarjet surgery. IR and ER muscles strength was evaluated with Con-Trex® dynamometer, with subjects seated and at a 45° shoulder abduction angle in scapular plane. IR and ER muscle fatigue was determined after 10 concentric repetitions at 180° · s(-1) through the fatigue index, the percent decrease in performance (DP), and the slope of peak torque decrease. There were no differences in rotator muscles fatigue between NG and CG. In OG, 3 months post-surgery, IR DP of operated shoulder was significantly (P < 0.001) higher than presurgery and 6 and 21 months post-surgery. Rotator muscles fatigability was not associated with recurrent anterior instability. After surgical stabilization, there was a significantly higher IR fatigability in the operated shoulder 3 months post-surgery, followed by recovery evidenced 6 months post-surgery and long-term maintenance over 21 months.

Meropenem versus imipenem-cilastatin in intraabdominal infections requiring surgery

In a multicentre, open, randomised study, the efficacy and tolerability of intravenous meropenem (1 g every 8 h, infusion or bolus) was compared with that of intravenous imipenem/cilastatin (1 g every 8 h, infusion) in 232 hospitalised patients with moderate to severe intra-abdominal infections. At the end of therapy, a satisfactory clinical response (cure or improvement) was seen in 79/82 (96%) evaluable meropenem patients and 83/88 (94%) imipenem/cilastatin patients; this was still seen at follow-up (57/63; 90% and 58/66; 88%, respectively). A satisfactory bacteriological response (elimination or presumed elimination) was seen in 69/82 (84%) meropenem patients and 71/88 (81%) imipenem/cilastatin patients at the end of therapy and in 52/62 (84%) and 55/70 (79%), respectively, at follow-up, There was a high level of clinical cure or improvement(95% for both treatment groups) in the 120 patients (60 in each group) who had polymicrobial infections. <p>A similar incidence of adverse events was seen in each group: 45/116 patients in the meropenem group (72 events) and 42/116 patients in the imipenem/cilastatin group (65 events); the adverse event profiles were also similar, with injection site inflammation and elevated transaminases the most frequent in both groups. The results of this study indicate that monotherapy with meropenem was as effective and as well tolerated as the combination of imipenem/cilastatin in the treatment of moderate to severe intra-abdominal infections.

A comparison between joint coordinate system and attitude vector for multi-segment foot kinematics.

The joint angles of multi-segment foot models have been primarily described using two mathematical methods: the joint coordinate system and the attitude vector. This study aimed to determine whether the angles obtained through these two descriptors are comparable, and whether these descriptors have similar sensitivity to experimental errors. Six subjects walked eight times on an instrumented walkway while the joint angles among shank, hindfoot, medial forefoot, and lateral forefoot were measured. The angles obtained using both descriptors and their sensitivity to experimental errors were compared. There was no overall significant difference between the ranges of motion obtained using both descriptors. However, median differences of more than 6° were noticed for the medial-lateral forefoot joint. For all joints and rotation planes, both descriptors provided highly similar angle patterns (median correlation coefficient: R>0.90), except for the medial-lateral forefoot angle in the transverse plane (median R=0.77). The joint coordinate system was significantly more sensitive to anatomical landmarks misplacement errors. However, the absolute differences of sensitivity were small relative to the joints ranges of motion. In conclusion, the angles obtained using these two descriptors were not identical, but were similar for at least the shank-hindfoot and hindfoot-medial forefoot joints. Therefore, the angle comparison across descriptors is possible for these two joints. Comparison should be done more carefully for the medial-lateral forefoot joint. Moreover, despite different sensitivities to experimental errors, the effects of the experimental errors on the angles were small for both descriptors suggesting that both descriptors can be considered for multi-segment foot models.

Infections nosocomiales en médecine ambulatoire: importance et prévention [Importance and prevention of nosocomial infections in the outpatient setting]

The concept of nosocomial infections (or healthcare-related infections) applies to the outpatients clinics. However, data are scarce and imprecise in this setting compared with hospitals. The choice of preventive measures is therefore difficult. A lower risk in the outpatient facilities does not justify the complete implementation of hospital precautions. The latter can nevertheless be adapted since infection may be acquired during an ambulatory consultation through the same mechanisms as in hospitals. We propose a preventive strategy derived from standard precautions to be applied in every case, transmission-based precautions that are more rarely needed, and asepsis in case of invasive procedure.

Laparoscope use and surgical site infections in digestive surgery

Rapport de synthèse : But: comparer les taux d'infections du site chirurgical (ISC) en fonction de la voie d'abord, ouverte ou laparoscopique, pour 3 procédures : l'appendicectomie, la cholécystectomie et la colectomie. Evaluer l'effet de la laparoscopie sur l'ISC pour ces trois interventions. Contexte : la laparoscopie est associée à de nombreux avantages par rapport à la chirurgie ouverte. Parmi ceux-ci, des taux inférieurs d'ISC ont été rapportés lors de laparoscopie. Ceci a été décrit en particulier lors de cholécystectomie. Mais des biais tels que le manque de suivi après la sortie de l'hôpital, et certains facteurs confondants, auraient pu contribuer à l'observation de différences entre ces deux techniques. Méthode : étude descriptive basée sur des données collectées entre mars 1998 et décembre 2004 de manière prospective dans le cadre d'un programme de surveillance des ISC dans 8 hôpitaux suisses. Ce programme comportait un suivi standardisé après le départ de l'hôpital. Les taux d'ISC ont été comparés après interventions faites par laparoscopie et chirurgie ouverte. Différents paramètres pouvant influencer la survenue d'une infection ont été identifiés en utilisant des modèles de régression logistiques. Résultats : les taux d'ISC après interventions par laparoscopie et par voie ouverte ont été respectivement de 59/1051 (5.6%) versus 117/1417 (8.3%) après appendicectomie (p = 0.01), 46/2606 (1.7%) versus 35/144 (7.9%) après cholécystectomie (p < 0.0001), et 35/311 (11.3%) versus 400/1781 (22.5%) après colectomie (p < 0,0001). Après ajustement, les interventions par laparoscopie étaient associées à un taux inférieur d'ISC : odds ratio = 0.61 (IC 95% : 0.43 - 0.87) pour l'appendicectomie, 0.27 (0.16 - 0.43) pour la cholécystectomie et 0.43 (0.29 - 0.63) pour la colectomie. Discussion et conclusion : bien que les patients aient quitté plus tôt l'hôpital après une intervention laparoscopique, leur suivi à un mois a été identique, ce qui a permis d'éviter une sous-estimation des ISC après chirurgie laparoscopique. De plus, l'analyse multivariée a inclus de nombreux facteurs potentiellement confondants, et l'utilisation de la laparoscopie était indépendamment et significativement liée à un effet protecteur à l'égard de l'ISC. La laparoscopie lors d'appendicectomie, cholécystectomie et colectomie semble diminuer le taux d'ISC en comparaison à la même chirurgie pratiquée par voie ouverte. Lorsqu'elle est faisable, cette voie d'abord minimalement invasive devrait être préférée à la chirurgie ouverte.

Domestic and International Research Joint Ventures: The Effect of Collusion

We analyze the effect of research joint ventures (RJVs) on consumer welfare in an international context when collusion can occur. The main novelty of our analysis is to study the differentiated effect of domestic and international RJVs. The recent literature shows that RJVs with collusion harm consumers. However, our results introduce a qualifi cation to this statement: international RJVs with collusion might be bene ficial for consumers when internationalization costs are high. The EU and US competition policy advises against RJVs that facilitate collusion on the grounds of their expected negative effects. Our results suggest that antitrust authorities should distinguish between domestic and international RJVs and, in certain cases, be more benevolent with international RJVs.
