[Temporary recommendation for use on off-label baclofen: viewpoint of Prescribers of the CAMTEA system]. / La « recommandation temporaire d'utilisation ¼ sur le baclofène : point de vue des prescripteurs du dispositif CAMTEA.

The use of high dose baclofen for alcohol-dependence emerged in France from 2008 based on empirical findings, and is still off-label. However, due to the rapid increase in this prescribing practice, the French health authorities have decided to frame it using an extraordinary regulatory measure named "temporary recommendation for use" (TRU). Baclofen prescribers from CAMTEA, a regional team-based off-label system for supervising baclofen prescribing, which was developed much prior to the TRU, discuss herein the pros and cons of this measure and the applicability of its different aspects in the daily clinical practice.

Autobiographical memory and differentiation of schematic models in substance-dependent patients.

BACKGROUND AND OBJECTIVES: This study aims at investigating reduced autobiographical memory specificity in substance-dependent patients. We examined whether this phenomenon is related to undifferentiated schematic models of self and to depression and anxiety levels. We also investigated the maintenance of these impairments after early clinical remission. METHODS: Seventy-three dependent patients (including 30 active users, 23 methadone-maintained patients, 20 early abstinent patients) and 31 control participants were given Williams' and Scott's Autobiographical Memory Test (AMT) to evaluate the level of memory specificity. Depression and anxiety levels were assessed with the Hospital Anxiety and Depression Scale (HADS), and the ability of differentiation in affect-related schematic models of self with the Level of Emotional Awareness Scale (LEAS). RESULTS: Dependent patients recall less specific memories than control individuals to the AMT. For all the participants, only the ability to differentiate emotional states predicts the level of specificity, whereas reduced specificity is not linked to depression and anxiety levels. The results also show that reduced specificity is still observable in methadone-maintained patients and in abstinent patients. LIMITATIONS: Despite the absence of difference in the level of memory specificity in the three groups of dependent patients, we cannot state that reduced memory specificity is stable over time because non-active consumers may not remain in remission for a long period. CONCLUSIONS: Only a lack of emotional differentiation seems to impede the access to specific memories in dependent patients and in general population. The reduced memory specificity observed in dependent patients seems to last after recent clinical improvement.

Routine practice HCV infection screening with saliva samples: multicentric study in an intravenous drug user population.

OBJECTIVE: The purpose of this randomized multicentric study was to evaluate the diagnostic contribution of screening for HCV infection on saliva samples in day-to-day practice in the intravenous drug-user (IVDU) population. METHODS: Between January and May 2004, 274 presumably HCV-negative IVDU were screened for HCV infection in 15 centers in France (median age 29 years). After centralized randomization, screening tests were performed on blood samples (arm A) or saliva samples (arm B). Screening tests were performed in 78 subjects (28%) had never been screened before and in 196 subjects (72%) who had had a negative HCV screening test on average 12 months prior to the beginning of the study. In the event of a positive saliva test for anti-HCV Ab, a serum test for anti-HCV Ab was performed. In the event of a positive serum test for anti-HCV Ab, PCR was performed on serum to measure HCV-RNA. RESULTS: Fourteen individuals were positive for HCV RNA (7 in each arm). Six of these cases had not been detected before. In eight cases, the median time between the last negative screening test and study inclusion was 11 months (range 6-94 months). CONCLUSIONS: Viremia tests were positive in 5% percent of the target population, although one-third of the individuals in arm A (blood samples) were not tested. The saliva test may be a useful alternative in the event of refusal of a blood test or when poor venous conditions compromise venous puncture. A confirmatory blood test still remains difficult to obtain in nearly half of patients.
