Methadone blood concentrations are decreased by the administration of abacavir plus amprenavir.

Abacavir and amprenavir, a nucleoside reverse transcription inhibitor and a protease inhibitor, respectively, are new drugs used for the treatment of HIV. Methadone blood concentrations were measured in five addict patients receiving methadone maintenance therapy before and after introduction of abacavir plus amprenavir. The administration of these two drugs for a median period of 14 days resulted in a significant reduction (P = 0.043) of methadone concentration, with a median decrease to 35% of the original concentration (range 28-87%). Two patients reported on several occasions nausea in the morning before the intake of the daily methadone dose, which is compatible with withdrawal reaction to opioids. Because amprenavir is a cytochrome P4503A4 substrate and is involved in the metabolism of methadone, reduction of methadone concentrations could be explained by an induction of cytochrome P4503A4.

Viral Retinitis following Intraocular or Periocular Corticosteroid Administration: A Case Series and Comprehensive Review of the Literature.

Abstract Purpose: To describe viral retinitis following intravitreal and periocular corticosteroid administration. Methods: Retrospective case series and comprehensive literature review. Results: We analyzed 5 unreported and 25 previously published cases of viral retinitis following local corticosteroid administration. Causes of retinitis included 23 CMV (76.7%), 5 HSV (16.7%), and 1 each VZV and unspecified (3.3%). Two of 22 tested patients (9.1%) were HIV positive. Twenty-one of 30 (70.0%) cases followed one or more intravitreal injections of triamcinolone acetonide (TA), 4 (13.3%) after one or more posterior sub-Tenon injections of TA, 3 (10.0%) after placement of a 0.59-mg fluocinolone acetonide implant (Retisert), and 1 (3.3%) each after an anterior subconjunctival injection of TA (together with IVTA), an anterior chamber injection, and an anterior sub-Tenon injection. Mean time from most recent corticosteroid administration to development of retinitis was 4.2 months (median 3.8; range 0.25-13.0). Twelve patients (40.0%) had type II diabetes mellitus. Treatments used included systemic antiviral agents (26/30, 86.7%), intravitreal antiviral injections (20/30, 66.7%), and ganciclovir intravitreal implants (4/30, 13.3%). Conclusions: Viral retinitis may develop or reactivate following intraocular or periocular corticosteroid administration. Average time to development of retinitis was 4 months, and CMV was the most frequently observed agent. Diabetes was a frequent co-morbidity and several patients with uveitis who developed retinitis were also receiving systemic immunosuppressive therapy.

Nouveau regard sur l'information documentaire publique : régulation d'une ressource en émergence dans l'univers des archives, des bibliothèques et de l'administration suisses

Résumé : Ce travail jette un regard nouveau sur l'information documentaire publique. A travers l'analyse des régulations qui régissent l'archivage, la préservation du patrimoine documentaire et la gestion des documents au niveau national en Suisse, il propose en effet l'application d'un concept d'analyse fédérateur, habituellement exploité pour la compréhension du fonctionnement des res¬sources naturelles. Après avoir exposé que la création, la gestion et la préservation de l'information sont historiquement liées à l'exercice du pouvoir, au système politique en place et au développement des technologies de l'information, ce travail montre que - à la suite des importants changements dus au développe¬ment de la société du savoir et des nouvelles technologies de l'information - les politiques concernées en Suisse sont en train de converger. Ce mouve¬ment, signe de la lente reconnaissance de l'existence d'une ressource unique, va de pair avec le développement d'un système de règles. Cette ressource, désignée par le terme générique d'information, est en train de devenir un enjeu politique et économique fondamental : comme les ressources natu¬relles, elle exige de la part des acteurs publics une prise en charge appropriée afin d'assurer sa durabilité - c'est-à-dire sa capacité de renouvellement - en régulant les rivalités entre usages compétitifs, qui risquent de mettre cette ressource en péril. Ainsi, par l'application d'un modèle d'analyse appelé Régime institutionnel des ressources (RIR), ce travail évalue la durabilité de la ressource information en vérifiant l'existence et la mise en oeuvre de règles pour cha¬cun des usages identifiés de cette ressource. A partir des huit études de cas (consacrées aux archives d'Etat, aux Helvetica, aux données météoro¬logiques et climatologiques, aux données statistiques, aux données d'observation des sols, aux données de la mensuration officielle, aux don¬nées d'état civil et aux données de la taxe sur la valeur ajoutée), notre analyse qualitative montre que, si la durabilité de la ressource est assurée à court terme, elle ne l'est pas sur le long terme. En effet, en dépit des progrès significatifs qui ont été faits ces dernières années, notamment en termes de gestion des documents, le régime institu¬tionnel de la ressource information présente des failles : les principales rivalités existantes ne sont pas contrôlées par des régulations spécifiques. Ainsi, l'identification des informations disponibles, la traçabilité de celles-ci, la sélection de celles qu'il convient de préserver à long terme et, enfin, leur conservation physique continueront à poser problème à l'avenir. Le document se clôt sur l'encouragement à poursuivre les travaux scienti¬fiques et politiques dans ce domaine, dans le but de bénéficier enfin d'une compréhension plus approfondie des mécanismes qui le régissent.

Networks of Coordination : Swiss Business Associations as an Intermediary between Business, Politics and Administration during the 20th Century

Until the 1990's, Switzerland could be classified as either a corporatist, cooperative or coordinated market economy where non-market mechanisms of coordination among economic and political actors were very important. In this respect, Business Interest Associations (BIAs) played a key role. The aim of this paper is to look at the historical evolution of the five main peak Swiss BIAs through network analysis for five assorted dates during the 20th century (1910, 1937, 1957, 1980 and 2000) while relying on a database that includes more than 12,000 people. First, we examine the logic of membership in these associations, which allows us to analyze their position and function within the network of the Swiss economic elite. Until the 1980's, BIAs took part in the emergence and consolidation of a closely meshed national network, which declined during the two last decades of the 20th century. Second, we investigate the logic of influence of these associations by looking at the links they maintained with the political and administrative worlds through their links to the political parties and Parliament, and to the administration via the extra-parliamentary commissions (corporatist bodies). In both cases, the recent dynamic of globalization called into question the traditional role of BIAs.

Enhanced visuospatial memory following intracerebroventricular administration of nerve growth factor

The present work assessed the effects of intracerebroventricular injections of rh recombined human nerve growth factor (rh NGF) (5 micrograms/2.5 microl) at postnatal days 12 and 13 upon the development of spatial learning capacities. The treated rats were trained at the age of 22 days to escape onto an invisible platform at a fixed position in space in a Morris navigation task. For half of the subjects, the training position was also cued, a procedure aimed at facilitating escape and at reducing attention to the distant spatial cues. Later, at the age of 6 months, all the rats were trained in a radial-arm maze task. Treatment effects were found in both immature and adult rats. The injection of NGF improved the performance in the Morris navigation task in both training conditions. There was a significant reduction in the escape latency and an increased bias toward the training platform quadrant during probe trials. The most consistent effect was the precocious development of an adult-like spatial memory. In the radial-arm maze, the NGF-treated rats made significantly fewer reentries than vehicle rats and this effect was particularly marked in the treated female rats. Taken together, these experiments reveal that the development and the maintenance of an accurate spatial representation are tightly related to the development of brain structures facilitated by the action of NGF. Moreover, these experiments demonstrate that an acute pharmacological treatment that leads to a transient modification in the choline acetyltransferase activity can induce a behavioral change long after the treatment.
