Methadone treatments in a Swiss Region, 2001-2008: a registry-based analysis.

ABSTRACT: BACKGROUND: To determine, in a region of Switzerland, the duration of retention in opioid substitution treatments with methadone (OSTM), duration of treatment interruptions, probability of re-entry to treatment after a treatment interruption, and associated factors. METHODS: A secondary analysis of registry-based data was performed with patients (n = 2880) registered in the methadone treatment register database of the Public Health Service of the canton of Vaud between January 1, 2001 and June 30, 2008. Survival analysis and multivariate analysis was conducted. RESULTS: The probability of remaining on treatment was 69% at 1 year and 45% at 3 years (n =1666). One-third of patients remained on treatment beyond 5 years. The estimated hazard of leaving treatment was increased by a ratio of 1.31 in the case of a first treatment (P = 0.001), 1.83 for those without a fixed home (P < 0.001), and 1.29 for those younger than 30 years old (P < 0.001). The probability of having begun a new treatment after a first interruption was 21% at one year, 38% at 3 years, and 43% at 5 years (n = 1581). Factors at the interruption of treatment associated with a higher probability of re-entering were: interruption not due to methadone withdrawal, bad physical health, and higher methadone dose. CONCLUSIONS: OSTM are long-term (maintenance) treatments in Switzerland. Younger age, bad living conditions at entry, and first treatment are predictors of lower retention. Approximately one-half of patients who interrupt treatment will re-enter treatment within 5 years.

Evaluation of Gateway and Low-Cost Traffic-Calming Treatments for Major Routes in Small, Rural Communities, TR-523, 2007

Many rural communities have developed around highways or major county roads; as a result, the main street through small rural communities is often part of a high-speed rural highway. Highways and county roads are characterized by high speeds outside the city limits; they then transition into a reduced speed section through the rural community. Consequently, drivers passing through the community often enter at high speeds and maintain those speeds as they travel through the community. Traffic calming in small rural communities along major roadways is common in Europe, but the U.S. does not have experience with applying traffic-calming measures outside of major urban areas. The purpose of the project was to evaluate traffic-calming treatments on the major road through small Iowa communities using either single-measure low-cost or gateway treatments. The project was partially funded by the Iowa Highway Research Board (IHRB). The focus of the IHRB portion was to evaluate single-measure, low-cost, traffic-calming measures that are appropriate to major roads through small rural communities. Seven different low-cost traffic treatments were implemented and evaluated in five rural Iowa communities. The research evaluated the use of two gateway treatments in Union and Roland; five single-measure treatments (speed table, on-pavement “SLOW” markings, a driver speed feedback sign, tubular markers, and on-pavement entrance treatments) were evaluated in Gilbert, Slater, and Dexter.

Eczéma chronique des mains: traitements conventionnels et nouveautés [Chronic hand eczema, conventional and new treatments].

Chronic hand eczema is a frequent cause of consultation. In Europe and Switzerland, it's one of the main reasons for patients to interrupt their profession. The etiology is pluri-factorial. Atopic patients are more likely predisposed. Pruritus, associated to pain and bleeding, is intense. Psychosocial consequences are huge, making this illness to an important public health problem. Topical treatment and UV-light are the main therapeutical strategy but the results are often disappointing. Recently, alitretinoine (9-cis retinoic acid) became the treatment of second choice with good response, allowing patients to preserve a good quality of life and their job.

Subretinal neovascular membranes complicating uveitis : frequency, treatments and visual outcome

RESUME Les membranes néovasculaires (MNV) compliquent diverses pathologies ophtalmiques. Elles sont à l'origine d'une importante baisse de l'acuité visuelle lorsque elles se situent à proximité de la fovéa. A l'heure actuelle, peu de données relatives à leur association aux pathologies inflammatoires de l'oeil (uvéites) existent. Dans ce travail, la fréquence de MNV a été évaluée parmi 643 patients avec uvéite. Leur impact sur l'acuité visuelle ainsi que le pronostic en fonction des différents traitements effectués ont été étudiés. Les dossiers des 643 patients souffrant d'uvéite ont été étudiés. Les patients présentant une MNV ont été classés en trois groupes en fonction de l'importance de l'inflammation intraoculaire: élevée (2+ cellules dans le vitré), moyenne (1/2+ à 1+ cellules dans le vitré) ou absente (0 cellules dans le vitré). L'évolution de l'acuité visuelle fut considérée comme favorable (+VA: maintient de l'acuité visuelle ou gain d'une ou plusieurs lignes de Snellen) ou défavorable (-VA: perte d'une ou plusieurs lignes Snellen). Chez 9 patients, le traitement instauré a consisté, initialement, en l'administration orale de corticostéroïdes (CST) à haute dose qui, dans le cas d'évolution favorable (-FVA ou régression angiographique de la MNV), était arrêtée en doses dégressives. Dans les évolutions défavorables (-VA ou progression angiographique de la MNV), les CST étaient maintenus à dose moyenne en complémentation d'un traitement par thérapie laser (photothérapie dynamique (PDT), thermothérapie transpupillaire (TTT) ou laser Argon). Ce protocole thérapeutique ne fut appliqué chez trois patients en raison de la non disponibilité de PDT ou d'un diagnostic manqué d'uvéite. Douze patients sur 643 avec uvéite ont présenté une MNV. L'impact visuel moyen était de 4.5 lignes de Snellen et le temps moyen de suivi était de 19.5 mois. Deux patients avec inflammation intraoculaire élevée ont évolué favorablement sous CST seuls. Huit patients avec inflammation intraoculaire moyenne ont évolué favorablement sous CST seuls chez trois patients, alors que quatre patients ont nécessité une thérapie laser additionnelle. Le dernier patient ne fut traité que par thérapie laser sans CST (diagnostic manqué d'uvéite). Deux patients sans inflammation intraoculaire ont eu un pronostic défavorable sous CST seuls (pas d'autre alternative thérapeutique). Notre étude a démontré que les MNV sont une complication rare de l'uvéite qui, après traitement adéquat, ont un pronostic visuel relativement favorable. Bien que les CST semblent être la première modalité thérapeutique, les traitements laser devraient être adoptés tôt dans les situations d'inflammation intraoculaire moyenne ou absente.
