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.

Pregnancy-induced chromatin remodeling in the breast of postmenopausal women.

Early pregnancy and multiparity are known to reduce the risk of women to develop breast cancer at menopause. Based on the knowledge that the differentiation of the breast induced by the hormones of pregnancy plays a major role in this protection, this work was performed with the purpose of identifying what differentiation-associated molecular changes persist in the breast until menopause. Core needle biopsies (CNB) obtained from the breast of 42 nulliparous (NP) and 71 parous (P) postmenopausal women were analyzed in morphology, immunocytochemistry and gene expression. Whereas in the NP breast, nuclei of epithelial cells were large and euchromatic, in the P breast they were small and hyperchromatic, showing strong methylation of histone 3 at lysine 9 and 27. Transcriptomic analysis performed using Affymetrix HG_U133 oligonucleotide arrays revealed that in CNB of the P breast, there were 267 upregulated probesets that comprised genes controlling chromatin organization, transcription regulation, splicing machinery, mRNA processing and noncoding elements including XIST. We concluded that the differentiation process induced by pregnancy is centered in chromatin remodeling and in the mRNA processing reactome, both of which emerge as important regulatory pathways. These are indicative of a safeguard step that maintains the fidelity of the transcription process, becoming the ultimate mechanism mediating the protection of the breast conferred by full-term pregnancy.

Treatment algorithm for moderate to severe ulcerative colitis.

The care for a patient with ulcerative colitis (UC) remains challenging despite the fact that morbidity and mortality rates have been considerably reduced during the last 30 years. The traditional management with intravenous corticosteroids was modified by the introduction of ciclosporin and infliximab. In this review, we focus on the treatment of patients with moderate to severe UC. Four typical clinical scenarios are defined and discussed in detail. The treatment recommendations are based on current literature, published guidelines and reviews, and were discussed at a consensus meeting of Swiss experts in the field. Comprehensive treatment algorithms were developed, aimed for daily clinical practice.

Abortion trends 1990-1999 in a Swiss region and determinants of abortion recurrence.

OBJECTIVE: To assess age- and nationality-specific trends in abortion rates over the last decade, and to describe women's characteristics, identifying risk factors for repeated abortion. METHODS: From 1990-1999, the Health Department of Canton Vaud (Switzerland) received 13'857 abortion requests from residents aged 14-49. Population data were obtained to compute rates. RESULTS: Both the number of abortions (1400 annually) as well as their rate (8.9 per thousand women [95% confidence interval (CI) 7.3-10.5]) were stable over the decade in question. The rate of abortion for foreign women, especially from ex-Yugoslavia and Africa, was twice that for Swiss women. Half of the requests came from single women, 43% had a low education level, and half were childless. The main reason for requesting termination of pregnancy was psychosocial (93%). The mean gestational age was 7.7 weeks (SD +/- 2.3), but 96% of requests were submitted before 12 weeks. Sixty-three percent of women reported that they had used no contraception, 36% the condom and 17% the pill. Among requests, the adjusted risk of repeated abortion (22% of abortion candidates) was greater among divorced/separated/widowed women (odds ratio [OR] 1.9 [95% CI 1.5-2.4]), unemployed women (OR 1.8 [95% CI 1.5-2.1]), and those who had not attended university (OR 1.6 [95% CI 1.1-2.2]). CONCLUSIONS: Although Swiss law only permitted abortion under strict conditions, this procedure was widely available in Vaud, which nevertheless has one of the lowest rates worldwide. Efforts must be intensified to ensure universal access to family planning services, especially for foreign women and adolescents. Professionals should also target "repeaters" to provide personalised counselling.

Association of smoking and nicotine dependence with pre-diabetes in young and healthy adults.

INTRODUCTION: Several studies have shown an increased risk of type 2 diabetes among smokers. Therefore, the aim of this analysis was to assess the relationship between smoking, cumulative smoking exposure and nicotine dependence with pre-diabetes. METHODS: We performed a cross-sectional analysis of healthy adults aged 25-41 in the Principality of Liechtenstein. Individuals with known diabetes, Body Mass Index (BMI) >35 kg/m² and prevalent cardiovascular disease were excluded. Smoking behaviour was assessed by self-report. Pre-diabetes was defined as glycosylated haemoglobin between 5.7% and 6.4%. Multivariable logistic regression models were done. RESULTS: Of the 2142 participants (median age 37 years), 499 (23.3%) had pre-diabetes. There were 1,168 (55%) never smokers, 503 (23%) past smokers and 471 (22%) current smokers, with a prevalence of pre-diabetes of 21.2%, 20.9% and 31.2%, respectively (p <0.0001). In multivariable regression models, current smokers had an odds ratio (OR) of pre-diabetes of 1.82 (95% confidential interval (CI) 1.39; 2.38, p <0.0001). Individuals with a smoking exposure of <5, 5-10 and >10 pack-years had an OR (95% CI) for pre-diabetes of 1.34 (0.90; 2.00), 1.80 (1.07; 3.01) and 2.51 (1.80; 3.59) (p linear trend <0.0001) compared with never smokers. A Fagerström score of 2, 3-5 and >5 among current smokers was associated with an OR (95% CI) for pre-diabetes of 1.27 (0.89; 1.82), 2.15 (1.48; 3.13) and 3.35 (1.73; 6.48) (p linear trend <0.0001). DISCUSSION: Smoking is strongly associated with pre-diabetes in young adults with a low burden of smoking exposure. Nicotine dependence could be a potential mechanism of this relationship.

The neutrophil NLRC4 inflammasome selectively promotes IL-1β maturation without pyroptosis during acute Salmonella challenge.

The macrophage NLRC4 inflammasome drives potent innate immune responses against Salmonella by eliciting caspase-1-dependent proinflammatory cytokine production (e.g., interleukin-1β [IL-1β]) and pyroptotic cell death. However, the potential contribution of other cell types to inflammasome-mediated host defense against Salmonella was unclear. Here, we demonstrate that neutrophils, typically viewed as cellular targets of IL-1β, themselves activate the NLRC4 inflammasome during acute Salmonella infection and are a major cell compartment for IL-1β production during acute peritoneal challenge in vivo. Importantly, unlike macrophages, neutrophils do not undergo pyroptosis upon NLRC4 inflammasome activation. The resistance of neutrophils to pyroptotic death is unique among inflammasome-signaling cells so far described and allows neutrophils to sustain IL-1β production at a site of infection without compromising the crucial inflammasome-independent antimicrobial effector functions that would be lost if neutrophils rapidly lysed upon caspase-1 activation. Inflammasome pathway modification in neutrophils thus maximizes host proinflammatory and antimicrobial responses during pathogen challenge.

Genetic and phenotypic population divergence on a microgeographic scale in brown trout.

Salmonid populations of many rivers are rapidly declining. One possible explanation is that habitat fragmentation increases genetic drift and reduces the populations' potential to adapt to changing environmental conditions. We measured the genetic and eco-morphological diversity of brown trout (Salmo trutta) in a Swiss stream system, using multivariate statistics and Bayesian clustering. We found large genetic and phenotypic variation within only 40 km of stream length. Eighty-eight percent of all pairwise F(ST) comparisons and 50% of the population comparisons in body shape were significant. High success rates of population assignment tests confirmed the distinctiveness of populations in both genotype and phenotype. Spatial analysis revealed that divergence increased with waterway distance, the number of weirs, and stretches of poor habitat between sampling locations, but effects of isolation-by-distance and habitat fragmentation could not be fully disentangled. Stocking intensity varied between streams but did not appear to erode genetic diversity within populations. A lack of association between phenotypic and genetic divergence points to a role of local adaptation or phenotypically plastic responses to habitat heterogeneity. Indeed, body shape could be largely explained by topographic stream slope, and variation in overall phenotype matched the flow regimes of the respective habitats.

New gene functions in megakaryopoiesis and platelet formation.

Platelets are the second most abundant cell type in blood and are essential for maintaining haemostasis. Their count and volume are tightly controlled within narrow physiological ranges, but there is only limited understanding of the molecular processes controlling both traits. Here we carried out a high-powered meta-analysis of genome-wide association studies (GWAS) in up to 66,867 individuals of European ancestry, followed by extensive biological and functional assessment. We identified 68 genomic loci reliably associated with platelet count and volume mapping to established and putative novel regulators of megakaryopoiesis and platelet formation. These genes show megakaryocyte-specific gene expression patterns and extensive network connectivity. Using gene silencing in Danio rerio and Drosophila melanogaster, we identified 11 of the genes as novel regulators of blood cell formation. Taken together, our findings advance understanding of novel gene functions controlling fate-determining events during megakaryopoiesis and platelet formation, providing a new example of successful translation of GWAS to function.

Subclinical thyroid dysfunction and the risk of heart failure events: an individual participant data analysis from 6 prospective cohorts.

BACKGROUND: American College of Cardiology/American Heart Association guidelines for the diagnosis and management of heart failure recommend investigating exacerbating conditions such as thyroid dysfunction, but without specifying the impact of different thyroid-stimulation hormone (TSH) levels. Limited prospective data exist on the association between subclinical thyroid dysfunction and heart failure events. METHODS AND RESULTS: We performed a pooled analysis of individual participant data using all available prospective cohorts with thyroid function tests and subsequent follow-up of heart failure events. Individual data on 25 390 participants with 216 248 person-years of follow-up were supplied from 6 prospective cohorts in the United States and Europe. Euthyroidism was defined as TSH of 0.45 to 4.49 mIU/L, subclinical hypothyroidism as TSH of 4.5 to 19.9 mIU/L, and subclinical hyperthyroidism as TSH <0.45 mIU/L, the last two with normal free thyroxine levels. Among 25 390 participants, 2068 (8.1%) had subclinical hypothyroidism and 648 (2.6%) had subclinical hyperthyroidism. In age- and sex-adjusted analyses, risks of heart failure events were increased with both higher and lower TSH levels (P for quadratic pattern <0.01); the hazard ratio was 1.01 (95% confidence interval, 0.81-1.26) for TSH of 4.5 to 6.9 mIU/L, 1.65 (95% confidence interval, 0.84-3.23) for TSH of 7.0 to 9.9 mIU/L, 1.86 (95% confidence interval, 1.27-2.72) for TSH of 10.0 to 19.9 mIU/L (P for trend <0.01) and 1.31 (95% confidence interval, 0.88-1.95) for TSH of 0.10 to 0.44 mIU/L and 1.94 (95% confidence interval, 1.01-3.72) for TSH <0.10 mIU/L (P for trend=0.047). Risks remained similar after adjustment for cardiovascular risk factors. CONCLUSION: Risks of heart failure events were increased with both higher and lower TSH levels, particularly for TSH ≥10 and <0.10 mIU/L.

Vascular dysfunction in children conceived by assisted reproductive technologies: underlying mechanisms and future implications.

Epidemiological studies in humans have demonstrated a relationship between pathological events during fetal development and increased cardiovascular risk later in life and have led to the so called "Fetal programming of cardiovascular disease hypothesis". The recent observation of generalised vascular dysfunction in young apparently healthy children conceived by assisted reproductive technologies (ART) provides a novel and potentially very important example of this hypothesis. This review summarises recent data in ART children demonstrating premature subclinical atherosclerosis in the systemic circulation and pulmonary vascular dysfunction predisposing to exaggerated hypoxia-induced pulmonary hypertension. These problems appear to be related to the ART procedure per se. Studies in ART mice demonstrating premature vascular aging and arterial hypertension further demonstrate the potential of ART to increase cardiovascular risk and have allowed to unravel epigenetic alterations of the eNOS gene as an underpinning mechanism. The roughly 25% shortening of the life span in ART mice challenged with a western style high-fat-diet demonstrates the potential importance of these alterations for the long-term outcome. Given the young age of the ART population, data on cardiovascular endpoints will not be available before 20 to 30 years from now. However, already now cohort studies of the ART population are needed to early detect cardiovascular alterations with the aim to prevent or at least optimally treat cardiovascular complications. Finally, a debate needs to be engaged on the future of ART and the consequences of its exponential growth for public health.

Androgen dependence of hirsutism, acne, and alopecia in women : retrospective analysis or 228 patients investigated for hyperandrogenism

RAPPORT DE SYNTHESE : L'hirsutisme, l'acné et l'alopécie chez la femme sont souvent associés à des troubles menstruels et à une production excessive d'androgènes, raison pour laquelle ces symptômes cutanés font l'objet d'évaluation endocrinienne. L'hyperandrogénie affecte 5 à 10 % des femmes en âge de reproduction et constitue un motif fréquent de consultation. Récemment, les sociétés d'endocrinologie ont émis des recommandations sur l'investigation et le traitement de l'hyperandrogénie. Longtemps confrontés à la demande de patientes souffrant d'hirsutisme, d'acné ou d'alopécie, nous avons décidé d'effectuer une approche diagnostique et thérapeutique comportant des dosages hormonaux et un traitement antiandrogénique. Un grand nombre de patientes a été ainsi étudié au fil des années. Les paramètres mesurés incluaient la testostérone plasmatique totale, l'androstènedione, le sulfate de déhydroépiandrostérone (DHEAS), la sex hormone-binding globulin (SHBG) et la testostérone salivaire. Cette dernière est considérée comme un bon reflet de la testostérone libre plasmatique, indépendamment des protéines de liaison. L'analyse rétrospective des dossiers nous a permis de comparer nos données avec celles de la littérature. Des 318 dossiers de patientes ayant consulté notre Service pour hirsutisme, acné ou alopécie pendant 6 ans, 228 ont pu être retenus pour une évaluation adéquate. Chez les patientes présentant ces symptômes de façon isolée, les taux d'androgènes et la prévalence de l'oligo-aménorhée étaient plus élevés en cas d'hirsutisme qu'en cas d'alopécie, avec des valeurs intermédiaires en cas d'acné. Aucun des androgènes mesurés ne permettait, à lui seul, d'identifier tous les cas d'hyperandrogénie, mais la testostérone salivaire a montré la meilleure corrélation positive avec l'hirsutisme, alors que la testostérone plasmatique totale montrait la moins bonne corrélation, et l'androstènedione, le DHEAS et la SHBG des corrélations intermédiaires (corrélation négative pour la SHBG). De plus, au cours du traitement antiandrogénique, la testostérone salivaire a montré l'abaissement proportionnel le plus marqué de tous les androgénes mesurés. Comparées aux patientes originaires d'Europe centrale, les patientes originaires d'Europe du sud consultaient avec des degrés d'hirsutisme supérieurs, mais aucune différence n'a été observée dans les corrélations entre l'hirsutisme et les taux hormonaux de ces deux groupes. En l'absence d'un nombre suffisant d'échographies ovariennes, .la prévalence du syndrome des ovaires polykystiques a été probablement sous-estimée (63 patientes, 27.6 % des cas), au bénéfice du diagnostic d'hyperandrogénie avec euménorrhée (101, 44.3 %); les autres diagnostics étaient: androgénes normaux (51, 22.4%), SHBG basse isolée (7, 3.1%), hyperplasie surrénalienne congénitale non-classique (4, 1.8%), et tumeur ovarienne (2, 0.9%). Nous avons comparé les divers traitements médicaux de l'hirsutisme publiés au cours des 25 dernières années, quant à leur efficacité et leur coût. La sensibilisation à l'insuline avec metformin est moins efficace, mais aussi moins chère. L'anti-androgène flutamide et l'inhibiteur de la 5-α reductase finastéride figurent parmi les traitements les plus performants, mais ils sont aussi les plus chers. Le traitement anti-androgénique et de suppression hormonale avec acétate de cyprotérone et éthinyloestradiol, utilisé dans cette étude, est également parmi les plus efficaces, tout en étant nettement moins cher. Cette étude est la première comparant directement les taux d'androgènes et la prévalence de l'oligoaménorrhée dans les 3 symptômes cutanés d'hyperandrogénie, hirsutisme, acné et alopécie, et elle démontre leur différente dépendance aux androgènes. La salive apparait comme un milieu de choix pour identifier ces patientes et la recommandation actuelle de doser la testostérone plasmatique totale en premier, pour distinguer l'hyperandrogénie de l'hirsutisme idiopathique, nous paraît inadéquate. Nous proposons, au contraire, d'abandonner ce dosage au profit de celui de la testostérone salivaire. Par ailleurs, notre étude infirme l'hypothèse d'une sensibilité cutanée accrue aux androgènes chez les femmes originaires du sud de l'Europe. Finalement, elle est la seule à comparer les effets cliniques, les changements biologiques et le coût annuel des traitements publiés de l'hirsutisme.

Le contrat de franchise et le redressement et la liquidation judiciaire

Introduction générale : 1 L'essor du contrat de franchise se situe dans un contexte de mutation économique ainsi que de développement en France des nouvelles techniques de la distribution au cours des années 1960. Le commerce indépendant, jusque-là prépondérant, a décliné au profit de la distribution intégrée qui tendait à canaliser les circuits de distribution afin d'agir notamment sur les prix. On assiste alors à l'émergence de la grande distribution (hypermarchés, supermarchés), aux côtés de nouvelles techniques d'intégration commerciale qu'on appelle commerce associé, dans lequel le distributeur est indépendant sur le plan juridique et dans sa gestion, et n'est pas contraint à une exclusivité de son approvisionnement. En parallèle, s'impose en France et un peu partout en Europe, la franchise dont l'esprit est proche du commerce associé, mais qui s'appuie sur le prestige et la réputation des marques connues du public, pour assurer la distribution des produits de la franchise dans des points de vente ayant une identité reconnaissable. La distribution par la franchise conservait aussi l'esprit du commerce de proximité, privilégiant l'idée de boutique plutôt que celle de grands magasins. Avec l'évolution de la franchise, on assiste aujourd'hui à une cohabitation entre grandes surfaces et petites boutiques, qui se côtoient sans antagonisme dans des grands ensembles commerciaux. La franchise est considérée par certains auteurs comme une figure fondamentale du commerce contemporaine. 2 Le succès de la franchise s'explique par les nombreuses qualités et avantages que beaucoup s'accordent à lui reconnaître. Harmonisant les techniques les plus modernes de vente, elle permet néanmoins une gestion à dimension humaine et surtout indépendante au franchisé. Elle encourage à la création d'une entreprise (petite ou moyenne) par des particuliers désireux d'exercer une activité indépendante, tout en leur assurant une certaine sécurité dans leur investissement du fait de la notoriété de la marque mais aussi de l'assistance et du conseil d'un franchiseur compétent dans son domaine. La franchise permet au franchisé sous l'enseigne d'une marque de renom, de proposer des produits répondant aux normes de qualité et de proposer la même garantie aux consommateurs, dans tous les points de vente de la marque franchisée. Quant au créateur de la franchise, le franchiseur, il peut assurer une diffusion nationale et internationale de ses produits sans consentir d'investissements financiers. 3 La franchise est le contrat par lequel le franchiseur concède le droit d'exploiter la franchise au franchisé ; elle est aussi la méthode commerciale par laquelle se réalise cette exploitation. Elle en désigne à la fois le cadre et le contenu. Le contrat de franchise permet ainsi de prévoir le cadre contractuel des partenaires pour l'exploitation de la méthode commerciale mise au point et expérimentée par le franchiseur. Ce contrat est né de la pratique, et évolue dans un cadre juridique souple et hétérogène composé de règles venant à la fois du droit commun, du droit de la distribution et du droit de la concurrence interne et communautaire. Cette originalité lui a permis d'évoluer et de trouver les adaptations nécessaires pour suivre les besoins des activités à exercer. Il a ainsi commencé par se développer dans la vente de produits puis la prestation de services pour convenir ensuite à des activités libérales, telles que le conseil et le management. A l'intérieur de ce cadre non contraignant, le contrat de franchise impose en revanche un ensemble complexe d'obligations, lesquelles impliquent pour les partenaires une grande implication personnelle et commerciale. La jurisprudence a d'ailleurs largement contribué à préciser le contenu de nombreuses notions liées à ce contrat. 4 Une des fortes spécificités du contrat de franchise est d'une part, son caractère d'intuitus personae qui rend essentiel le choix de la personne du cocontractant, et d'autre part, l'idée de collaboration étroite entre les partenaires qui leur permet à la fois de détenir une grande force dans la réussite de la réitération de la franchise, mais qui peut aussi être source de fragilités. Il y a d'ailleurs un équilibre à trouver entre des réalités paradoxales : l'intégration du franchisé dans un réseau protégé par l'imposition de normes ainsi que le contrôle exercé par le franchiseur et le respect de l'indépendance juridique de ce franchisé. 5 Malgré ces promesses indéniables de réussite du franchisé grâce à la réitération des méthodes éprouvées par le franchiseur, de nombreux écueils guettent la franchise, et ont été largement traités par la doctrine et la jurisprudence. On peut citer notamment la difficulté de trouver un équilibre entre la supériorité économique du franchiseur et l'indépendance juridique du franchisé, la nécessité d'informer correctement et suffisamment le franchisé sur les perspectives de la franchise grâce à l'obligation d'information précontractuelle. Ces difficultés peuvent déboucher sur une «faillite » du franchisé. Placés devant cette situation, commence pour les partenaires une période de turbulences, au cours de laquelle les principes fondateurs du contrat, intuitus personae et collaboration sont remis en question. 6 Les difficultés d'application des mesures de la loi sur le redressement et la liquidation judiciaires, au partenaire en difficulté et au contrat de franchise n'ont pas encore reçu de réponse satisfaisante dans la pratique. En effet, comment peuvent être préservées la spécificité de la relation contractuelle basée sur l'intuitus personae et la forte collaboration en pareille situation ? Quel sera le traitement d'un contrat de franchise dans la procédure collective ? Dès lors que la «faillite » concerne un contrat de franchise, le cadre habituel et respectueux des spécificités de ce contrat fait place à un ensemble de règles d'exception qui vont s'appliquer uniformément à tous les contrats de l'entreprise en difficulté, en vue de la redresser. Précisément, le contrat de franchise est un révélateur des difficultés d'application uniforme et indifférenciée des règles de la «faillite » à des situations présentant des particularités. 7 Le franchisé est celui qui dans l'exécution normale du contrat, doit constamment chercher à équilibrer les rapports contractuels à la fois pour préserver son autonomie juridique, et garder une collaboration avec le franchiseur de manière à s'inspirer de ses conseils et des recettes de sa réussite ; il doit également s'assurer dans le cadre d'une bonne collaboration que le franchiseur exécute ses obligations quant à la transmission de l'information ainsi que la fourniture d'une assistance suffisante, mais sans dépassement. Cet équilibre comme on le verra n'est pas facile à trouver. Dans la «faillite », le franchisé n'aura pas beaucoup le choix des moyens. Son contrat sera soumis aux décisions des mandataires de la procédure qui pourront prendre certaines mesures ne tenant pas compte de la spécificité des liens contractuels entre le franchisé et le franchiseur. 8 La position de faiblesse du franchisé dans la relation de franchise, conduit à envisager principalement les conséquences de la «faillite » sur sa situation, plutôt que d'envisager d'un côté la «faillite » du franchisé et de l'autre côté, la «faillite » du franchiseur. Ce choix de porter l'attention sur la situation du franchisé s'explique par les grandes particularités qui ressortent en pareil cas. La présente étude se propose donc dans une première partie d'étudier précisément le contrat de franchise dans son cadre général ainsi que dans ses particularités, en faisant ressortir à la fois ses fortes particularités et les risques de «faillite »qu'il présente (chapitre unique). Dans une deuxième partie, il est question du sort du contrat de franchise en cas de «faillite » de l'une des parties, en particulier le franchisé, des effets de l'intuitus personae, qui est remis en question lors de la cession judiciaire du contrat (chapitre I) et des effets de l'étroite collaboration entre les parties, qui se posent lorsque le franchiseur a dépassé ses prérogatives dans le contrôle de la gestion, et en général de tout préjudice ayant consisté à aggraver la situation financière du franchisé. Se posent alors les possibilités de mise en jeu de la responsabilité du franchiseur (chapitre II). Il reste à préciser que des aspects de la «faillite » du franchiseur peuvent également être abordés lorsqu'ils revêtent un intérêt pour cette étude.

Late removal of retrievable caval filters.

The advent of retrievable caval filters was a game changer in the sense, that the previously irreversible act of implanting a medical device into the main venous blood stream of the body requiring careful evaluation of the pros and cons prior to execution suddenly became a "reversible" procedure where potential hazards in the late future of the patient lost most of their weight at the time of decision making. This review was designed to assess the rate of success with late retrieval of so called retrievable caval filters in order to get some indication about reasonable implant duration with respect to relatively "easy" implant removal with conventional means, i.e., catheters, hooks and lassos. A PubMed search (www.pubmed.gov) was performed with the search term "cava filter retrieval after 30 days clinical", and 20 reports between 1994 and 2013 dealing with late retrieval of caval filters were identified, covering approximately 7,000 devices with 600 removed filters. The maximal duration of implant reported is 2,599 days and the maximal implant duration of removed filters is also 2,599 days. The maximal duration reported with standard retrieval techniques, i.e., catheter, hook and/or lasso, is 475 days, whereas for the retrievals after this period more sophisticated techniques including lasers, etc. were required. The maximal implant duration for series with 100% retrieval accounts for 84 days, which is equivalent to 12 weeks or almost 3 months. We conclude that retrievable caval filters often become permanent despite the initial decision of temporary use. However, such "forgotten" retrievable devices can still be removed with a great chance of success up to three months after implantation. Conventional percutaneous removal techniques may be sufficient up to sixteen months after implantation whereas more sophisticated catheter techniques have been shown to be successful up to 83 months or more than seven years of implant duration. Tilting, migrating, or misplaced devices should be removed early on, and replaced if indicated with a device which is both, efficient and retrievable.

Excessive alcohol consumption in young men: is there an association with their earlier family situation? A baseline-analysis of the C-SURF-study (Cohort Study on Substance Use Risk Factors).

AIMS: To determine whether parental factors earlier in life (parenting, single parent family, parental substance use problem) are associated with patterns of alcohol consumption among young men in Switzerland. METHODS: This analysis of a population based sample from the Cohort Study on Substance Use Risk Factors (C-SURF) included 5,990 young men (mean age 19.51 years), all attending a mandatory recruitment process for the army. These conscripts reported on parental monitoring and rule-setting, parental behaviour and family structure. The alcohol use pattern was assessed through abstention, risky single occasion drinking (RSOD), volume drinking and dependence. Furthermore, the impact of age, family socio-economic status, educational level of the parents, language region and civil status was analysed. RESULTS: A parental substance use problem was positively associated with volume drinking and alcohol dependence in young Swiss men. Active parenting corresponded negatively with RSOD, volume drinking and alcohol dependence. Single parent family was not associated with a different alcohol consumption pattern compared to standard family. CONCLUSION: Parental influences earlier in life such as active parenting (monitoring, rule-setting and knowing the whereabouts) and perceived parental substance use problem are associated with alcohol drinking behaviour in young male adults. Therefore, health professionals should stress the importance of active parenting and parental substance use prevention in alcohol prevention strategies.

Defining responses to therapy and study outcomes in clinical trials of invasive fungal diseases: Mycoses Study Group and European Organization for Research and Treatment of Cancer consensus criteria.

Invasive fungal diseases (IFDs) have become major causes of morbidity and mortality among highly immunocompromised patients. Authoritative consensus criteria to diagnose IFD have been useful in establishing eligibility criteria for antifungal trials. There is an important need for generation of consensus definitions of outcomes of IFD that will form a standard for evaluating treatment success and failure in clinical trials. Therefore, an expert international panel consisting of the Mycoses Study Group and the European Organization for Research and Treatment of Cancer was convened to propose guidelines for assessing treatment responses in clinical trials of IFDs and for defining study outcomes. Major fungal diseases that are discussed include invasive disease due to Candida species, Aspergillus species and other molds, Cryptococcus neoformans, Histoplasma capsulatum, and Coccidioides immitis. We also discuss potential pitfalls in assessing outcome, such as conflicting clinical, radiological, and/or mycological data and gaps in knowledge.
