BACKGROUND: Internet is commonly used by the general population, notably for health information-seeking. There has been little research into its use by patients treated for a psychiatric disorder. AIM: To evaluate the use of internet by patients with psychiatric disorders in searching for general and medical information. METHODS: In 2007, 319 patients followed in a university hospital psychiatric out-patient clinic, completed a 28-items self-administered questionnaire. RESULTS: Two hundred patients surveyed were internet users. Most of them (68.5%) used internet in order to find health-related information. Only a small part of the patients knew and used criteria reflecting the quality of contents of the websites consulted. Knowledge of English and private Internet access were the factors significantly associated with the search of information on health on Internet. CONCLUSIONS: Internet is currently used by patients treated for psychiatric disorders, especially for medical seeking information.

We present a high-quality (>100× depth) Illumina genome sequence of the leaf-cutting ant Acromyrmex echinatior, a model species for symbiosis and reproductive conflict studies. We compare this genome with three previously sequenced genomes of ants from different subfamilies and focus our analyses on aspects of the genome likely to be associated with known evolutionary changes. The first is the specialized fungal diet of A. echinatior, where we find gene loss in the ant's arginine synthesis pathway, loss of detoxification genes, and expansion of a group of peptidase proteins. One of these is a unique ant-derived contribution to the fecal fluid, which otherwise consists of "garden manuring" fungal enzymes that are unaffected by ant digestion. The second is multiple mating of queens and ejaculate competition, which may be associated with a greatly expanded nardilysin-like peptidase gene family. The third is sex determination, where we could identify only a single homolog of the feminizer gene. As other ants and the honeybee have duplications of this gene, we hypothesize that this may partly explain the frequent production of diploid male larvae in A. echinatior. The fourth is the evolution of eusociality, where we find a highly conserved ant-specific profile of neuropeptide genes that may be related to caste determination. These first analyses of the A. echinatior genome indicate that considerable genetic changes are likely to have accompanied the transition from hunter-gathering to agricultural food production 50 million years ago, and the transition from single to multiple queen mating 10 million years ago.

Objectifs - Identifier les facteurs de vulnérabilité sociaux et médicaux associés au recours multiple aux consultations des urgences. - Déterminer si les patients à recours multiple sont plus à même de combiner ces facteurs dans un système d'assurance universelle. Méthode Il s'agit d'une étude cas-contrôle rétrospective basée sur l'étude de dossiers médico-administratifs comparant des échantillons randomisés de patients à recours multiple à des patients n'appartenant pas à cette catégorie, au sein des urgences du Centre Hospitalier Universitaire Vaudois et de la Policlinique Médicale Universitaire de Lausanne. Les auteurs ont défini les patients à recours multiple comme comptabilisant au moins quatre consultations aux urgences durant les douze mois précédents. Les patients adultes (>18 ans) ayant consulté les urgences entre avril 2008 et mars 2009 (période d'étude) étaient inclus ; ceux quittant les urgences sans décharge médicale étaient exclus. Pour chaque patient, le premier dossier d'urgence informatisé inclus dans la période d'étude était sélectionné pour l'extraction des données. Outre les variables démographiques de base, les variables d'intérêt comprennent des caractéristiques sociales (emploi, type de résidence) et médicales (diagnostic principal aux urgences). Les facteurs sociaux et médicaux significatifs ont été utilisés dans la construction d'un modèle de régression logistique, afin de déterminer les facteurs associés avec le recours multiple aux urgences. De plus, la combinaison des facteurs sociaux et médicaux a été étudiée. Résultats Au total, 359/Γ591 patients à recours multiple et 360/34'263 contrôles ont été sélectionnés. Les patients à recours multiple représentaient moins d'un vingtième de tous les patients des urgences (4.4%), mais engendraient 12.1% de toutes les consultations (5'813/48'117), avec un record de 73 consultations. Aucune différence en termes d'âge ou de genre n'est apparue, mais davantage de patients à recours multiples étaient d'une nationalité autre que suisse ou européenne (n=117 [32.6%] vs n=83 [23.1%], p=0.003). L'analyse multivariée a montré que les facteurs de vulnérabilité sociaux et médicaux les plus fortement associés au recours multiple aux urgences étaient : être sous tutelle (Odds ratio [OR] ajusté = 15.8; intervalle de confiance [IC] à 95% = 1.7 à 147.3), habiter plus proche des urgences (OR ajusté = 4.6; IC95% = 2.8 à 7.6), être non assuré (OR ajusté = 2.5; IC95% = 1.1 à 5.8), être sans emploi ou dépendant de l'aide sociale (OR ajusté = 2.1; IC95% = 1.3 à 3.4), le nombre d'hospitalisations psychiatriques (OR ajusté = 4.6; IC95% = 1.5 à 14.1), ainsi que le recours à au moins cinq départements cliniques différents durant une période de douze mois (OR ajusté = 4.5; IC95% = 2.5 à 8.1). Le fait de comptabiliser deux sur quatre facteurs sociaux augmente la vraisemblance du recours multiple aux urgences (OR ajusté = 5.4; IC95% = 2.9 à 9.9) ; des résultats similaires ont été trouvés pour les facteurs médicaux (OR ajusté = 7.9; IC95% = 4.6 à 13.4). La combinaison de facteurs sociaux et médicaux est fortement associée au recours multiple aux urgences, puisque les patients à recours multiple étaient dix fois plus à même d'en comptabiliser trois d'entre eux (sur un total de huit facteurs, IC95% = 5.1 à 19.6). Conclusion Les patients à recours multiple aux urgences représentent une proportion modérée des consultations aux urgences du Centre Hospitalier Universitaire Vaudois et de la Policlinique Médicale Universitaire de Lausanne. Les facteurs de vulnérabilité sociaux et médicaux sont associés au recours multiple aux urgences. En outre, les patients à recours multiple sont plus à même de combiner les vulnérabilités sociale et médicale que les autres. Des stratégies basées sur le case management pourraient améliorer la prise en charge des patients à recours multiple avec leurs vulnérabilités afin de prévenir les inégalités dans le système de soins ainsi que les coûts relatifs.

The aim of this article is to show the classical parameters of Shadowlands by R. Attenborough, with a screenplay by W. Nicholson, on C. S. Lewis's life and work. Based upon an accurate reading of Lewis's works, the author of this article proposes to interpret the opposition Lewis / Gresham as the translation into the real life of the opposition between the Platonic or idealistic and the Aristotelian or materialistic temperaments which was already maintained by Coleridge. In any case, there are many classical references which must be taken into account in order to understand to what extent C. S. Lewis's Christianity is also a classic Christianity, that is, a Greek and Latin one.

Schizotypy, defined in terms of commonly occurring personality traits related to the schizophrenia spectrum, has been an important construct for understanding the neurodevelopment and stress-diathesis of schizophrenia. However, as schizotypy nears its sixth decade of application, it is important to acknowledge its impressively rich literature accumulating outside of schizophrenia research. In this article, we make the case that schizotypy has considerable potential as a conceptual framework for understanding individual differences in affective and social functions beyond those directly involved in schizophrenia spectrum pathology. This case is predicated on (a) a burgeoning literature noting anomalies in a wide range of social functioning, affiliative, positive and negative emotional, expressive, and social cognitive systems, (b) practical and methodological features associated with schizotypy research that help facilitate empirical investigation, and (c) close ties to theoretical constructs of central importance to affective and social science (eg, stress diathesis, neural compensation). We highlight recent schizotypy research, ie providing insight into the nature of affective and social systems more generally. This includes current efforts to clarify the neurodevelopmental, neurobiological, and psychological underpinnings of affiliative drives, hedonic capacity, social cognition, and stress responsivity systems. Additionally, we discuss neural compensatory and resilience factors that may mitigate the expression of stress-diathesis and functional outcome, and highlight schizotypy's potential role for understanding cultural determinants of social and affective functions.

PURPOSE: A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. METHODS: Eight patients were treated in our institution between 2001 and 2011. All patients were discussed by a multidisciplinary tumor board, and an en bloc surgical resection by posterior perineal access only or by combined anterior/posterior accesses was planned based on tumor extension. RESULTS: Seven patients underwent radical surgery, and one was treated by using local cryotherapy alone due to low performance status. Three misdiagnosed patients had primary surgery at another hospital with R1 margins. Reresection margins in our institution were R1 in two and R0 in one, and all three recurred. Four patients were primarily operated on at our institution and had en bloc surgery with R0 resection margins. One had local recurrence after 18 months. The overall morbidity rate was 86% (6/7 patients) and was mostly related to the perineal wound. Overall, 3 out of 7 resected patients were disease-free at a median follow-up of 2.9 years (range, 1.6-8.0 years). CONCLUSION: Our experience confirms the importance of early correct diagnosis and of an R0 resection for a sacral chordoma invading pelvic structures. It is a rare disease that requires a challenging multidisciplinary treatment, which should ideally be performed in a tertiary referral center.
