Sleep disorders are very common in depression. They have been quantitatively and qualitatively described by polysomnographical recordings. It is of interest to know how treatments act on polysomnographical data. In this article, we propose to evaluate five treatment approaches proposed for depressive illness. Pharmacological treatment induces marked changes… (More)
Formation of resilient biofilms on medical devices colonized by pathogenic microorganisms is a major cause of health-care associated infection. While in vitro biofilm analyses led to promising anti-biofilm approaches, little is known about their translation to in vivo situations and on host contribution to the in vivo dynamics of infections on medical… (More)
The double-blind controlled trials between benzodiazepines and antidepressants show that benzodiazepines have not specific antidepressive action in depression. The benzodiazepines exert limited effect on the anxiety of endogenous and melancholia. They have definitive properties in neurotic depressions and mixed anxious-depressive states. In theses states,… (More)
The core symptoms of post-traumatic stress disorder (PTSD) include persistent reexperiencing of the traumatic event, avoidance of stimuli associated with the trauma, and autonomic hyperarousal. Many neurotransmitter systems and neurobiologic mechanisms may account for these primary symptoms of PTSD. Severe psychological trauma results in the parallel… (More)
Subjects with posttraumatic stress disorder exhibit abnormalities in many psychobiological systems. Studies of the effects of stress on learning and memory processes suggest that fear conditioning, behavioural sensitisation, and a failure of extinction may be important in the persistence and reexperiencing of traumatic memories and stress sensitivity. All… (More)
Traditional scoring of sleep EEG in depressed patients shows abnormalities in sleep maintenance, sleep architecture, REM sleep, the distribution of slow wave and REM sleep during the night. Computerized analysis that comprises the period-amplitude analysis procedure and spectral analysis discloses changes in delta activity and distribution of delta… (More)
The first controlled trials of antidepressants show up a delay of antidepressant effect to one or two weeks, with sedative or stimulant early effects. More recently, several controlled trials founded on more stringent criterions (DSM III, period of pre-therapeutic placebo of one minimal week, frequent quotations etc.) have showed up a delay of… (More)
Two cases illustrate psychotherapeutic aspects of surgical intensive cares for psychiatric patients. Comparison with their style of expression in art-therapy allows a better understanding in their relations with the technical and non human environment.
