Modèle «en étoile» des benzodiazépines.
Benzodiazepines have been considered the treatment of choice for a variety of neuropsychiatric disorders. They are currently much more controversial and drugs considered less dangerous are generally preferred. This article summarizes the characteristics of the different benzodiazepines present on the Belgian market. It describes abuse and dependenc...

... anxioly- tiques dans les troubles anxieux. Afin de per- mettre la visualisation rapide de ces différences cliniques, des chercheurs liégeois ont mis au point un modèle «en étoile» (5), évaluant cinq paramètres. Cette représentation graphique a permis de mettre en évidence des différences cliniques nettes entre les différentes benzodia- zépines ( fig. ...
... La prescription d'une benzodiazépine est une option souvent évitable et est surtout loin de constituer un élément important de la prise en charge (8). Les benzodiazépines peuvent entraîner des effets secondaires importants comme la somnolence, des troubles de la mémoire et de la concentration, des cauchemars, des effets paradoxaux (agressivité, nervosité), une baisse de libido, une indifférence affective et, surtout, induire une dépendance physique et psychologique. ...
Burnout or professional fatigue syndrome is the result of exposure to a situation in which the strategies of the subject who are supposed to manage the stresses of the environment become outdated and inoperative. An imbalance is created between the demands and the material, operational and psychological resources to cope with them. Many health professions are confronted with the challenge of managing burnout, but the general practitioner is very often on the front line. After a first article devoted to the epidemiology, diagnosis, causes and consequences of the burnout, this second article is focusing on its therapeutic management, through listening, sick leave, dietary supplements, antidepressants, behavioural and cognitive therapy, professional coaching and multidisciplinary approach.
Mental stress, such as anxiety and conflict, causes physiological changes such as dysregulation of autonomic nervous activity, depression, and gastric ulcers. It also induces glucocorticoid production and changes in hippocampal brain-derived neurotrophic factor (BDNF) levels. We previously reported that Acanthopanax senticosus HARMS (ASH) exhibited anxiolytic activity. Thus, we attempted to identify the anxiolytic constituents of ASH and investigated its influence on hippocampal BDNF protein expression in male Sprague Dawley rats administered chlorogenic acid (CHA), ( +)-syringaresinol–di–O–β-d-glucoside (SYG), or a mixture of both (Mix) for 1 week using the open field test (OFT) and improved elevated beam walking (IEBW) test. As with ASH and the benzodiazepine anxiolytic cloxazolam (CLO), Mix treatment significantly increased locomotor activity in the OFT. CHA and Mix increased the time spent in the open arm in the IEBW test. SYG and Mix treatment inhibited the significant increase in normalized low-frequency power, indicative of sympathetic nervous activity, and significant decrease in normalized high-frequency power, indicative of parasympathetic nervous activity, as observed in the IEBW test. SYG and Mix treatment significantly increased hippocampal BDNF protein expression. The combination of CHA and SYG possibly induces anxiolytic behavior and modulates autonomic regulation, activates hippocampal BDNF signaling as with ASH.
