[Table des matières] Généralités sur la violence domestique: Définition de la violence domestique, Prise en charge: possibilités et limites, Dépistage de la violence domestique, Signes et symptômes évoquant un contexte de violence domestique &. La situation spécifique des femmes migrantes. - Documentation: Marche à suivre: check-list, Consentement, Constat médical en cas de violence domestique, Examen physique, Attestation. - Annexes: Bases légales, Gynécologie des enfants et adolescentes, Caisse maladie et éléments financiers, Coordonnées des centres spécialisés, Centres cantonaux d'aide aux victimes d'infraction (Centres LAVI), Littérature et liens. - Suppléments: Marche à suivre: check-list, Spécimens de constat médical [Editorial (extrait)] Le groupe de travail «Abus sexuels au cabinet médical» - constitué voici quelques années par la Société Suisse de Gynécologie et d'Obstétrique - s'est vu chargé par le président de la société d'élaborer un guide pratique pour aborder la violence domestique. En Suisse, des études d'envergure montrent qu'une femme sur quatre au cours de sa vie et une femme sur dix durant les !" derniers mois sont confrontées à la violence. Ces études révèlent un lien étroit entre de nombreux problèmes de santé et le fait de subir de la violence conjugale. La moitié des femmes touchées présentent des problèmes de santé physiques et deux tiers des problèmes de santé psychiques ou des troubles d'ordre psychosomatiques. Et ce sont ces problèmes qui amèneront les femmes à consulter leur médecin. Le groupe de travail poursuit l'objectif d'améliorer la prise en charge des femmes concernées par la violence. En effet, aussi longtemps que la cause réelle des symptômes et des plaintes, à savoir le fait de vivre dans un contexte de violence, n'est pas dépistée, aucune mesure thérapeutique ne pourra avoir d'impact durable sur la santé de la patiente. Les femmes concernées par la violence domestique s'adressent de préférence à leur médecin. De ce fait, les gynécologues, au sein de leur cabinet et dans les cliniques, vont entrer en contact avec ces femmes. Il est donc important que chacun dispose des connaissances nécessaires à leur prise en charge.

Les maladies chroniques représentent un fardeau important pour la société, en termes de morbidité, dépendance, qualité de vie, mortalité et coûts de la santé. La prise en charge des maladies chroniques constitue ainsi une priorité des systèmes de santé. Tandis que des programmes de prévention et prise en charge des maladies chroniques («prevention and chronic disease management») ont été mis sur pieds depuis plus d'une décennie d'abord en Amérique du Nord puis en Europe, leur développement en Suisse est récent. Ces programmes sont explicitement structurés et organisés, centrés sur les patients et comportent constamment un élément d'éducation thérapeutique. De plus, ils impliquent un travail en équipe ainsi que des prises en charge stratifiées en fonction de la sévérité de la maladie et des besoins des patients, et basées sur les preuves de leur efficacité. Il est important que les médecins et autres professionnels de la santé, ainsi que tous les autres acteurs du système sanitaire reconnaissent la nécessité de mettre en place des modalités adéquates et efficaces de prise en charge des patients présentant des maladies chroniques, participent à leur développement et les soutiennent.

Tobacco smoking is a major public health issue and a better understanding of tobacco addiction represents an important challenge. Many factors are involved in tobacco addiction, including genetic factors. Taking them into account in smoking cessation programs would allow to better adapt these programs to individual characteristics and improve their rate of success. Given enzymatic induction by tobacco smoke, smoking cessation can nevertheless have important consequences on the metabolism of some drugs, that have to be taken into consideration. Here we present different clinical and genetic aspects of smoking and of smoking cessation. A dose adjustment of drugs influenced by tobacco smoke is proposed when quitting smoking.

During the first steps of reverse transcription of the retroviral genome, sequences present at the extremities of the RNA are used to reconstitute a host cell PolII promoter. The assembly of the promoter occurs by template switching, which takes advantage of a direct repeat at the ends of the RNA molecule. These steps are catalysed by the viral reverse transcriptase, which carries an intrinsic RNaseH activity that is probably also involved therein. To study the role of the RNaseH activity in this first template-switching event, an in vitro system has been developed based on primer extensions of synthetic RNAs. When an RNA was reverse transcribed with wild-type reverse transcriptase in the presence of a second RNA the 3' part of which was repeated at the 5' end of the first one, extension products could be observed corresponding to a chimeric cDNA comprising both RNA species. This template switching could not be detected when a mutant reverse transcriptase lacking the RNaseH activity was used. The results show that the RNaseH activity is needed to remove the 5' RNA sequences from the cDNA:RNA hybrid thereby enabling its translocation to another RNA containing an appropriate complementary target sequence.

Human immunodeficiency virus type 1 (HIV-1) variants resistant to protease (PR) and reverse transcriptase (RT) inhibitors may display impaired infectivity and replication capacity. The individual contributions of mutated HIV-1 PR and RT to infectivity, replication, RT activity, and protein maturation (herein referred to as "fitness") in recombinant viruses were investigated by separately cloning PR, RT, and PR-RT cassettes from drug-resistant mutant viral isolates into the wild-type NL4-3 background. Both mutant PR and RT contributed to measurable deficits in fitness of viral constructs. In peripheral blood mononuclear cells, replication rates (means +/- standard deviations) of RT recombinants were 72.5% +/- 27.3% and replication rates of PR recombinants were 60.5% +/- 33.6% of the rates of NL4-3. PR mutant deficits were enhanced in CEM T cells, with relative replication rates of PR recombinants decreasing to 15.8% +/- 23.5% of NL4-3 replication rates. Cloning of the cognate RT improved fitness of some PR mutant clones. For a multidrug-resistant virus transmitted through sexual contact, RT constructs displayed a marked infectivity and replication deficit and diminished packaging of Pol proteins (RT content in virions diminished by 56.3% +/- 10.7%, and integrase content diminished by 23.3% +/- 18.4%), a novel mechanism for a decreased-fitness phenotype. Despite the identified impairment of recombinant clones, fitness of two of the three drug-resistant isolates was comparable to that of wild-type, susceptible viruses, suggestive of extensive compensation by genomic regions away from PR and RT. Only limited reversion of mutated positions to wild-type amino acids was observed for the native isolates over 100 viral replication cycles in the absence of drug selective pressure. These data underscore the complex relationship between PR and RT adaptive changes and viral evolution in antiretroviral drug-resistant HIV-1.

In general practice, vitamin B12 levels are measured when searching an origin for an anemic status (usually megaloblastic anemia), for various neurological disorders (usually polyneuropathy) or for neurocognitive disorders. Although the pathologies associated with vitamin B12 deficiency are well known, hypervitaminemic B12 status is often fortuitous and frequent finding. The aim of this article is to present the disease entities associated with hypervitaminemia B12, the clinical implications of this dysvitaminosis and a practical approach when this laboratory abnormality is found.

A guideline group of pediatric rheumatologist experts elaborated guidelines related to the management of idiopathic juvenile arthritis in association with the Haute Autorité de santé (HAS). A systematic search of the literature published between 1998 and August 2008 and indexed in Pubmed was undertaken. Here, we present the guidelines for diagnosis and treatment in oligoarticular and polyarticular juvenile idiopathic arthritis (except for spondylarthropathy and rheumatoid arthritis).

Monitoring of T-cell responses in genital mucosa has remained a major challenge because of the absence of lymphoid aggregates and the low abundance of T cells. Here we have adapted to genital tissue a sensitive real-time reverse transcription-PCR (TaqMan) method to measure induction of gamma interferon (IFN-gamma) mRNA transcription after 3 h of antigen-specific activation of CD8 T cells. For this purpose, we vaccinated C57BL/6 mice subcutaneously with human papillomavirus type 16 L1 virus-like particles and monitored the induction of CD8 T cells specific to the L1(165-173) H-2D(b)-restricted epitope. Comparison of the responses induced in peripheral blood mononuclear cells and lymph nodes (LN) by L1-specific IFN-gamma enzyme-linked immunospot assay and TaqMan determination of the relative increase in L1-specific IFN-gamma mRNA induction normalized to the content of CD8b mRNA showed a significant correlation, despite the difference in the readouts. Most of the cervicovaginal tissues could be analyzed by the TaqMan method if normalization to glyceraldehyde-3-phosphate dehydrogenase mRNA was used and a significant L1-specific IFN-gamma induction was found in one-third of the immunized mice. This local response did not correlate with the immune responses measured in the periphery, with the exception of the sacral LN, an LN draining the genital mucosa, where a significant correlation was found. Our data show that the TaqMan method is sensitive enough to detect antigen-specific CD8 T-cell responses in the genital mucosa of individual mice, and this may contribute to elaborate effective vaccines against genital pathogens.
