En Suisse, un peu moins de 5 % de la population se déclarent musulmans. Originaires pour la majeure partie des grandes vagues migratoires de la fin du XXe siècle, les musulmans helvétiques sont le plus souvent identifiés individuellement. Ce livre présente la réalité institutionnelle et peu connue de l'islam en Suisse à partir de plusieurs enquêtes menées sur la manière dont il s'organise. Sa présence est très diversifiée selon les contextes cantonaux différents et les origines culturelles bien contrastées d'un musulman des Balkans, du Maghreb ou de la Turquie. Ces recherches menées par des sociologues et des politologues dessinent une mosaïque qui montre à partir de l'islam pratiquant et confessant qu'il ne peut être réduit aux formes conservatrices et violentes que certains considèrent comme la traduction obligée de toute posture musulmane. Cet ouvrage propose un portrait contrasté de l'islam en Suisse avec, d'une part, des ensembles qui tentent d'organiser légitimement leur culte et de maintenir leur héritage religieux et, d'autre part, des défis déterminants à relever pour l'intégration des fidèles, comme les liens avec le pays d'origine, l'indépendance financière des mosquées ou les questions relatives aux revendications religieuses ou culturelles de l'identité musulmane. A partir de la réalité musulmane, ce livre expose toute l'ambiguïté de nos sociétés « tolérantes » et « ouvertes », mais démunies et contradictoires face à l'émergence récente de la pluralité religieuse.

Introduction.- Since the work of the "International Association for the Study of Pain" (IASP), complex regional pain syndrome type 1 (CRPS I) or algodystrophy includes motor disorders (tremor, dystony, myoclony) as diagnosis criterion. This can lead to confusion with some neurologic disorders which can wrongly be considered as CRPS I. The following observation illustrates this problem.Observation.- A 31-year-old man was hospitalised in a rehabilitation clinic in April 2007 with suspected CRPS I with persistent pain in the left leg. In 2005, the patient underwent ligament reconstruction at the right ankle. In May 2006, a recurrence of his ankle sprain was treated conservatively. The course of this pathology was unfavourable with an extension of the pain areas (leg and foot) as well as an appearance of abnormal motion. Toe motion in abduction was observed (especially T5) followed by a flexion cramp; an hypoesthesia in the sural nerve area, a scar allodynia and discrete vasomotor disorders. The scintigraphy was compatible with a stage 2 algodystrophy. Lower limb electromyography was normal; measurement of pseudo periodic activity of the motor unit at the foot level (abductor of the 5th toe, 4th interosseous). A "Painful legs and moving toes syndrome" was diagnosed which was treated with gabapentin and carbamazepine with a partial improvement.Discussion.- The "Painful legs and moving toes syndrome" is a rare pathology rehabilitation specialists should recognize. The origin is often peripheral nerve damage. The medullar interneuron activation (between the dorsal and ventral horn) is considered as the source of the efferent motor nerves which are responsible for the abnormal movements. This observation illustrates the need for a demanding approach before establishing the diagnosis of CRPS I and the respect of the 4th criterion of the ASP (exclusion of this syndrome when another pathology may explain pain and dysfunction).

Dysmenorrhea is common in adolescent years, especially after the onset of ovulatory cycles, usually 2 to 3 years after menarche. Pain and symptoms are responsible for school absenteeism and interruption of sports and social activities. OBJECTIVES: This study aims to measure the prevalence of severe dysmenorrhea and its consequences on adolescent girls in Switzerland. Treatment of dysmenorrhea is discussed and recommendations for clinical practice are given. STUDY DESIGN: Cross sectional survey (SMASH 02) on a nationally representative sample of adolescents (n=7548; 3340 females), aged 16 to 20 years who attended post-mandatory education. A self-administered questionnaire was used to assess the severity of dysmenorrhea and its consequences on daily life pursuit of medical help and medications used. RESULTS: Among 3340 girls, 86.6% suffered from dysmenorrhea-related symptoms: 12.4% described having severe dysmenorrhea and 74.2% moderate dysmenorrhea. Girls with severe dysmenorrhea described heavier consequences on daily activities compared with girls without dysmenorrhea: 47.8% of girls with severe dysmenorrhea reported staying at home and 66.5% declared reducing their sportive activities. Yet, fewer than half have consulted a physician for this complaint and even fewer were treated properly. RECOMMENDATION: The pediatrician has a pivotal role in screening young patients for dysmenorrhea, as well as, educating and effectively treating adolescent girls with menstruation-associated symptoms. Non-steroidal anti-inflammatory drugs are considered the first-line of treatment for dysmenorrhea, and adolescents with symptoms that do not respond to this treatment for 3 menstrual periods should be offered combined oestroprogestative contraception and must be followed up, as non-responders may have an underlying organic pathology. CONCLUSION: Dysmenorrhea is a frequent health problem in adolescent years and adolescent care providers should be able to care for these patients in an efficient way.

AIMS: Adolescent mental health problems require treatment and care that are adapted to their needs. To evaluate this issue, it was decided to implement a multidimensional instrument focused on a global approach to adolescent social and behavioural functioning, combined with the ICD-10 classification. METHODS: The combination of an assessment interview and a classification tool enabled the method to integrate the measurement of several domains of patient-based outcome rather than focus on the measurement of symptoms. A group of 68 adolescents from an inpatient unit were compared with 67 adolescents from the general population. RESULTS: Results suggest that adolescents from the care unit adopt significantly riskier behaviour compared with adolescents from the control group. As expected, the main problems identified refer to the psychological and familial areas. A cluster analysis was performed and provided three different profiles: a group with externalizing disorders and two groups with internalizing disorders. On the basis of a structured interview it was possible to obtain information in a systematic way about the adolescents' trajectory (delinquency, physical and sexual abuse, psychoactive substance use). CONCLUSION: It was shown that treatment and care should not focus exclusively on mental health symptoms, but also upon physical, psychological and social aspects of the adolescent. A global approach helps in the consideration of the multitude of factors which must be taken into account when working with people with serious mental health problems and may help to turn the care unit's activity more specifically towards the needs of these adolescents.

Contexte: Impression clinique que l'Etat de Stress Post-traumatique (ESPT) est sous-diagnostiqué dans la prise en charge des patients qui sont évalués dans le cadre d'une urgence psychiatrique. Objectifs: (i) identifier la prévalence de l'ESPT dans une unité d'urgence psychiatrique au moyen d'un instrument diagnostic et la comparer avec le diagnostic clinique retenu dans un échantillon historique (ii) évaluer la perception des cliniciens quant à l'utilisation systématique d'un instrument diagnostic Méthodes: la prévalence de l'ESPT a été évaluée chez des patients consécutifs (N = 403) qui ont bénéficié d'une consultation par des psychiatres de l'Unité urgence-crise du Service de Psychiatrie de Liaison (PLI) du CHUV, en utilisant le module J du Mini Mental Neuropsychologic Interview (MINI 5.0.0, version CIM-10). Ce résultat a été comparé avec la prévalence de l'ESPT mentionné comme diagnostic dans les dossiers (N = 350) d'un échantillon historique. La perception des médecins-assistants de psychiatrie quant au dépistage systématique de l'ESPT avec un instrument a été étudiée en se basant sur la conduite d'un focus group d'assistants travaillant dans l'Unité urgence-crise du PLI. Résultats: Parmi les patients (N = 316) évalués à l'aide de l'instrument diagnostic, 20,3% (n = 64) réunissaient les critères de l'ESPT. Cela constitue un taux de prévalence significativement plus élevé que la prévalence d'ESPT documentée dans les dossiers de l'échantillon historique (0,57%). Par ailleurs, la prévalence de l'ESPT est significativement plus élevée parmi les groupes socio- économiques précarisés, tels que réfugiés et sans papiers (50%), patients venant d'un pays à histoire de guerre récente (47,1%), patients avec quatre (44,4%) ou trois comorbidités psychiatriques (35,3%), migrants (29,8%) et patients sans revenus professionnels (25%). Le focus groupe composé de 8 médecins-assistants a révélé que l'utilisation systématique d'un outil- diagnostic ne convenait pas dans le setting d'urgence psychiatrique, notamment parce que l'instrument a été considéré comme non adapté à une première consultation ou jugé avoir un impact négatif sur l'entretien clinique. Toutefois, après la fin de l'étude, les médecins-assistants estimaient qu'il était important de rechercher activement l'ESPT et continuaient à intégrer les éléments principaux du questionnaire dans leur travail clinique. Conclusion et perspectives: cette étude confirme que l'ESPT est largement sous-diagnostiqué dans le contexte des urgences psychiatriques, mais que l'usage systématique d'un outil diagnostic dans ce cadre ne satisfait pas les praticiens concernés. Pour améliorer la situation et au vu du fait qu'un instrument diagnostic est considéré comme non-adapté dans ce setting, il serait peut-être bénéfique d'envisager un dépistage ciblé et/ou de mettre en place une stratégie de formation institutionnelle.

During their development, immature CD4+ CD8+ thymocytes become committed to either the CD4 or CD8 lineage. Subsequent complete maturation of CD4+ and CD8+ cells requires a molecular match of the expressed coreceptor and the MHC specificity of the TCR. The final size of the mature CD4+ and CD8+ thymic compartments is therefore determined by a combination of lineage commitment and TCR-mediated selection. In humans and mice, the relative size of CD4+ and CD8+ peripheral T cell compartments shows marked genetic variability. We show here that genetic variations in thymic lineage commitment, rather than TCR-mediated selection processes, are responsible for the distinct CD4/CD8 ratios observed in common inbred mouse strains. Genetic variations in the regulation of lineage commitment open new ways to analyze this process and to identify the molecules involved.

T cells belong to two mutually exclusive lineages expressing either alpha beta or gamma delta T-cell receptors (TCR). Although alpha beta and gamma delta cells are known to share a common precursor the role of TCR rearrangement and specificity in the lineage commitment process is controversial. Instructive lineage commitment models endow the alpha beta or gamma delta TCR with a deterministic role in lineage choice, whereas separate lineage models invoke TCR-independent lineage commitment followed by TCR-dependent selection and maturation of alpha beta and gamma delta cells. Here we review the published data pertaining to the role of the TCR in alpha beta/gamma delta lineage commitment and provide some additional information obtained from recent intracellular TCR staining studies. We conclude that a variant of the separate lineage model is best able to accommodate all of the available experimental results.

In the last decades, the globalized competition among cities and regions made them develop new strategies for branding and promoting their territory to attract tourists, investors, companies and residents. Major sports events - such as the Olympic Games, the FIFA World Cup or World and Continental Championships - have played an integral part in these strategies. Believing, with or without evidence, in the capacity of those events to improve the visibility and the economy of the host destination, many cities, regions and even countries have engaged in establishing sports events hosting strategies. The problem of the globalized competition in the sports events "market" is that many cities and regions do not have the resources - either financial, human or in terms of infrastructure - to compete in hosting major sports events. Consequently, many cities or regions have to turn to second-tier sports events. To organise those smaller events means less media coverage and more difficulty in finding sponsors, while the costs - both financial and in terms of services - stay high for the community. This paper analyses how Heritage Sporting Events (HSE) might be an opportunity for cities and regions engaged in sports events hosting strategies. HSE is an emerging concept that to date has been under-researched in the academic literature. Therefore, this paper aims to define the concept of HSE through an exploratory research study. A multidisciplinary literature review reveals two major characteristics of HSEs: the sustainability in the territory and the authenticity of the event constructed through a differentiation process. These characteristics, defined through multiple variables, give us the opportunity to observe the construction process of a sports event into a heritage object. This paper argues that HSEs can be seen as territorial resources that can represent a competitive advantage for host destinations. In conclusion, academics are invited to further research HSEs to better understand their construction process and their impacts on the territory, while local authorities are invited to consider HSEs for the branding and the promotion of their territory.

Tässä insinöörityössä selvitetään ABB Oy System AC -liiketoimintayksikön pakkaamon ulkoistamiseen liittyviä ongelmia sekä mahdollisia ratkaisuja näihin ongelmiin. Koko ongelman käsittely on liian laaja projektin yhdelle insinöörityölle. Tässä työssä keskitytään ratkaisemaan ko. ulkoistamiseen liittyvät keskeisimmät ACS800-kaappimoduulien kuljetuslogistiset ongelmat. Näitä ongelmia ovat kaappimoduulien kiinnitystarve kuljetusalustaansa sekä kuljetuspaketoinnin puuttuessa kaappimoduulien suojaaminen maantiekuljetuksen ajaksi. Työssä on otettu huomioon viranomaisten maantiekuljetuksia koskevat vaatimukset. Työssä on suunniteltu uusia kiinnitysvälineitä sekä muutoksia olemassa oleviin kuljetusalustoihin, joita käytetään tehtaan sisäisissä kaappimoduulien siirroissa. Kiinnitysvälineistä on tehty lujuuslaskelmia ja määritelty kiristysmomentteja. Tuotettavuuden ja kustannustehokkuuden kannalta on selvitetty kiinnitysvälineisiin soveltuvia materiaalivaihtoehtoja. Kuljetusalustojen muutoksista on myös tehty ohjeistusta. Tämän työn tulos on uusien kiinnitysvälineiden ja kuljetusalustojen mekaanisten muutosten suunnittelu. Samalla on todistettu, että kaappimoduulien siirto tehtaan ulkopuoliseen pakkaamoon ilman kuljetuspaketointia on teoriassa mahdollista.
