L'utilisation de l'Evangile de Thomas dans la recherche actuelle sur les paroles de Jésus

(Résumé de l'ouvrage) Ce volume regroupe des travaux menés sur le Jésus de l'histoire par des spécialistes de cette question fondatrice. Celle-ci connait, en effet, de vigoureuses impulsions dues à l'application de nouvelles méthodologies aux effets inattendus: sociologie du judaisme ancien, anthropologie des sociétés agraires, utilisation des écrits apocryphes chrétiens. Pour la première fois, des savants mondialement réputés sont présentés en français tels John S. Kloppenborg (Toronto) ou Ed P. Sanders (Durham). L'ouvrage est construit en sept parties: l'état de la recherche, le judaisme au temps de Jésus, le coeur de la théologie de Jésus, la tradition extracanonique chrétienne et la question du Jésus historique, Jésus dans le Nouveau Testament, les lectures juives de Jésus, le Jésus historique et la théologie.

Développement, implémentation et utilisation pratique d'un score diagnostique [Development, implementation and practical use of a diagnostic score].

In recent years many clinical prediction rules (CPR) have been developed. Before a CPR can be used in clinical practice, different methodical steps are necessary, from the development of the score, the internal and external validation to the impact study. Before using a CPR in daily practice family doctors have to verify how the rules have been developed and whether this has been done in a population similar to the population in which they would use them. The aim of this paper is to describe the development of a CPR, and to discuss advantages and risks related to the use of CPR in order to help family doctors in their choice of scores for use in their daily practice.

Evaluation éthique en psychologie : une utilisation respectueuse des différents instruments psychométriques

Trois psychologues de l'Université de Lausanne, Sophie Perdrix, Linda Charvoz et Jérôme Rossier, abordent dans leur article la relation complexe que le psychologue entretient avec les évaluations psychologiques. Ils plaident en faveur d'une utilisation respectueuse des différences individuelles des instruments d'évaluation et mettent en garde contre leurs aspects réductionnistes.

Einfluss von L-Carnitin-supplementierter total parenteraler Ernährung (TPE) auf die postoperative Fett- und Stickstoff-Utilisation [Effect of L-carnitine supplemented total parenteral nutrition on postoperative lipid and nitrogen utilization].

During episodes of trauma carnitine-free total parenteral nutrition (TPN) may result in a reduction of the total body carnitine pool, leading to a diminished rate of fat oxidation. Sixteen patients undergoing esophagectomy were equally and randomly divided and received isonitrogenous (0.2 gN/kg.day) and isocaloric (35 kcal/kg.day TPN over 11 days without and with L-carnitine supplementation (12 mg/kg.day). Compared with healthy controls, the total body carnitine pool was significantly reduced in both groups prior to the operation. Without supplementation carnitine concentrations were maintained, while daily provision of carnitine resulted in an elevation of total carnitine mainly due to an increase of the free fraction. Without supplementation the cumulative urinary carnitine losses were 11.5 +/- 6.3 mmol corresponding to 15.5% +/- 8.5% of the estimated total body carnitine pool. Patients receiving carnitine revealed a positive carnitine balance in the immediate postoperative phase, 11.1% +/- 19.0% of the infused carnitine being retained. After 11 days of treatment comparable values for respiratory quotient, plasma triglycerides, free fatty acids, ketone bodies, and cumulative nitrogen balance were observed. It is concluded that in the patient population studied here carnitine supplementation during postoperative TPN did not improve fat oxidation or nitrogen balance.

Pratique du scanner en Suisse: fréquence et évolution temporelle [CT utilisation in Switzerland: frequency and secular trends]

PURPOSE: This study analyzes CT examinations in Switzerland. MATERIALS AND METHODS: Using different sources (administrative data on the equipment, a 1998 nationwide inquiry into practices, and data provided by the Swiss University Hospitals of Basel, Zurich, and Lausanne), we determined the frequency of CT examinations (hospitals and private radiologists) in 1998 according to different descriptive variables and studied the progression in CT use over time. RESULTS: CT scanners increased by 7% between 1998 and 2004. The average annual number of CT examinations in 1998 was 46.3/1000 population, 3.4% of all radiological examinations in Switzerland in 1997-1998. The most frequent examination was CT of the skull (24%), while private radiology institutes perform more CTs of the spine. More CT examinations were performed for men than for women (sex ratio M/F=1.17). The average annual increase in CT in Swiss hospitals varied from 8% for Basel to 18% for Lausanne. Finally, the proportion of pediatric examinations was 5%; their numbers appear to be stabilizing. CONCLUSION: There is a significant increase in CT examinations. It is hoped that our study will heighten awareness among doctors of CT examinations in order to optimize their use.

Résultats anatomiques comparés à long terme de décollements de rétine avec prolifération vitréo-rétinienne opérés avec ou sans utilisation de perfluorocarbones liquides [Long-term comparative anatomic results of retinal detachment with vitreoretinal proliferation operated with or without using liquid perfluorocarbons].

PURPOSE: To investigate whether peroperative perfluorocarbon liquids (PFCL) improve the long term anatomical success of retinal detachment associated with severe proliferative vitreoretinopathy (PVR). PATIENTS AND METHODS: The charts of 62 successive patients operated on for retinal detachment associated with severe PVR were retrospectively analyzed. For one group of 39 patients PFCL were used intraoperatively to improve membrane dissection. The anatomical status of the two groups were compared one month after surgery and at least 6 months after silicone oil ablation. RESULTS: Anatomical success was observed in 84.6% in the group of patients operated with PFCL compared to 52% in the other group (P = 0.005). At the end of the follow up, anatomical success was observed in 64% of patients operated with PFCL compared to 61% in the control group (P = 0.8). However, recurrences were observed later in the group operated on with PFCL. CONCLUSION: Perfluorocarbons liquids significantly improve the initial reattachment of retinal detachment complicated with severe PVR, but they do not seem to improve their final anatomical status.

Attachement à la mère et au père, intersubjectivité et utilisation d'informations publiques.

La théorie de l'attachement est une théorie dyadique, par essence. Même si le père peut être reconnu comme une réelle figure d'attachement, en ce sens qu'il est susceptible de procurer à l'enfant une expérience de sécurité, la théorie reste essentiellement dyadique. Redéfinir la théorie de l'attachement dans une perspective triadique n'est pas sans poser des difficultés théoriques. Ace propos, nous suggérons une perspective inspirée par un concept d'écologie comportementale, celui de l'utilisation adaptative par les organismes d'informations publiques fournies par inadvertance par d'autres organismes, concept que nous étendrons à cette fin aux expressions émotionnelles. Nous proposons alors l'idée que dans la triade, chaque partenaire utilise ce type d'informations, fournies à la fois par chacun des autres partenaires ainsi que par les interactions ellesmêmes entre ces partenaires. L'utilisation de ces informations aurait, dans cette perspective, une fonction adaptative pour le maintien de la triade comme une entité soudée par des échanges d'expériences émotionnelles. The theory of attachment is essentially a dyadic theory. Even though the father is recognised as a real figure of attachment in that he brings a feeling of security to the child, basically the theory remains dyadic. Redefining the theory of attachment in a triadic perspective is not without raising difficult theoretical problems. This leads us to suggest a perspective inspired by the concept of ecological behaviour : the adaptative use of public information acquired inadvertently through other organisms, a concept applied here to emotional expression. We propose that in the triad each partner uses this type of information brought by the other partner as well as those very interactions between both partners. The use of information to maintain the triad as an entity bound by exchanges of emotional experience would be an adaptative function.
