TOPIC: Bereavement therapy as a catalyst for spiritual growth. PURPOSE: This study aims to review the literature and reflect on the bereavement therapy undertaken with two adolescents who had been bereaved during childhood. SOURCES: Research articles and books identified through a combination of electronic and manual searches. CONCLUSIONS: It would appear that grief therapy could facilitate spiritual growth in such circumstances. Further in-depth studies are required to identify how typical or atypical this experience is, and to contribute to the evidence base for working with bereaved children and adolescents. 相似文献

The psychological suffering of adolescents is a subject that has drawn an increasing amount of attention on the part of the public authorities, local and associative bodies, and of course psychotherapists themselves. While the psychiatric treatment of adolescent disorders is based upon wide ranging nosographic categories that are specific to this age group, new and clinical forms are appearing on the scene, as if they were, an expression of new suffering. This sudden visibility on the social front regarding problematical adolescent behavior has brought with it a concomitant increase in explanations attempting to put into perspective the diversity of so-called “deviant” behavioral patterns in adolescents in relation to the development of a new malaise in contemporary civilization. The author of this study has examined this phenomenon from an anthropological point of view, and has critically examined the possible link between the modifications in the present-day social environment, and the various types of behaviour that are considered to be indicative of underlying psychic suffering. By puting the social explanations of adolescent suffering into perspective vis a vis the proposed solution, such as this multiplied counselling services, the author shows the emergence of a widespread system involving and promoting a generalized “confession” and disclosure of the intimate, in wich listening to what is been said becomes less important than the underlying constraints on expression that it imposes. 相似文献

Abstract Simultaneous bilateral avulsions of the tibial tuberosity are rare injuries. The authors found only five reported cases in
the orthopedic literature. We add a further case of bilateral avulsions of the tibial tuberosity with the longest reported
follow-up. 相似文献

The purpose of this paper is to present the psychoanalytic individual psychodrama, as practiced in France within a psychiatric institution. After an overview of historical and theoretical issues, authors present a case report concerning the outcome of an adolescent suffering from schizophrenia, after ten years of treatment. The case analysis highlights the re-investment of mental functioning and the recover of the free association ability. Specially, authors describe the last year of the treatment and the pathways by which main psychical conflicts have been elaborated. 相似文献

The objective of this demonstration project was to determine if school-based harm minimization drug education was potentially acceptable and effective for junior and senior high school students in Nova Scotia. We conducted a four-year quasi-experimental intervention using mixed quantitative and qualitative methodologies. The intervention was a co-operative participatory research project with various activities determined by the participants. The project involved a partnership of four schools, two school boards, two regional addiction services, the provincial department of health, and a university. The outcomes evaluation was based on a sample of 1117 and 849 students in the intervention schools, compared with 3755 and 4247 students in the rest of the province, in 1998 and 2002, respectively. The evaluation of acceptability was based on an analysis of 491 documents generated from 1998 to 2002. The outcomes of effectiveness were specific risks and harmful consequences associated with substance use. We found that harm minimization was an acceptable approach to drug education targeting the senior high school population, and there was also some evidence of effectiveness in that age group in that the prevalence of several risks and negative consequences of substance use decreased significantly in the intervention schools relative to the rest of the province. In junior high school, harm minimization was found to not be an acceptable approach to drug education. This demonstration project provides evidence that school-based harm minimization may be acceptable and effective in senior high schools but may not be acceptable in junior high schools. 相似文献

BACKGROUND: Risperidone has been shown to be clinically effective for the treatment of aggressive behavior in children, yet no information is available regarding whether risperidone exhibits aggression-specific suppression in preclinical studies that use validated developmentally immature animal models of escalated aggression. Previously, we have shown that exposure to low doses of the psychostimulant cocaine-hydrochloride (.5 mg/kg intraperitoneally) during the majority of pubertal development (postnatal days [P]27-57) generates animals that exhibit a high level of offensive aggression. This study examined whether risperidone exerts selective aggression-suppressing effects by using this pharmacologic animal model of highly escalated offensive aggression. METHODS: Experimental hamsters were tested for offensive aggression after the acute administration of risperidone (.05-1.0 mg/kg, intraperitoneally). RESULTS: Risperidone dose-dependently reduced the highly aggressive phenotype, with a significant reduction observed at .1-.2 mg/kg for most aggressive responses measured. Experimental animals treated with higher doses of risperidone (.3-1.0 mg/kg) showed significant reductions in aggression and social interest toward intruders, indicating more general behavioral inhibition. CONCLUSIONS: These studies provide evidence that risperidone exerts specific aggression-suppressing effects in a developmentally immature animal model of escalated aggression. 相似文献
