Le psychodrame individuel chez les adolescents

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.     

De l'intérêt clinique du concept d'héboïdophrénie. À propos de deux cas de schizophrénie criminelle

Our clinical experience brings us to believe that not all patients suffering from schizophrenia are dangerous and this in spite of collective representations and dramatic happenings regularly reported by the media.Indeed among the important symptomatic dimensions that are classically bound to this illness, some semiological regroupments seem to predict hetero-aggressive risks more than others. And this perception seems even clearer when the investigation is widened to cover the history of the patient, his/her personality traits, relational modalities and psychic representations. Therefore the concept of heboidophrenia that had become obsolescent in present day nosographies can constitute a clinical model that is still pertinent and propitious for new reflexions. To illustrate our remarks we have decided to present two strikingly similar clinical cases in spite of a great contextual difference. They relate to two patients suffering from schizophrenia who are untypical due to their murderous criminal history. After a comparative discussion our reflexion will widen to whether one can foresee such acts in this type of patient, and to the possibility of medical care…. Under the aegis of the Law.     

Morel-Lavallée损伤诊疗进展

Morel-Lavallée(MLL)损伤是由剪切力等暴力使皮肤、皮下组织与深筋膜分离而引起的复杂的软组织闭合性撕脱损伤,疾病初期具有复杂性和隐蔽性,常因延迟诊断而导致感染、截肢、多器官衰竭甚至死亡等。目前,MLL的治疗尚无统一指南,需根据损伤情况及患者意愿综合考虑。在合并开放伤、骨折、神经血管肌腱损伤时,处理的优先顺序尚存在很大的争议。本文对MLL的发病机制、临床表现、影像学检查、治疗等进行综述,以提高临床对该类疾病的关注和认识。     

Exercice physique, carence estrogénique, monoxyde d'azote et remodelage osseux

Summary

Objectives

The aim of this paper is to emphasize the possible relationships established between estrogens and physical exercise and concerning bone metabolism. Nitric oxide (NO) might play an important role in such relationships.

Topics

Cellular metabolism of NO, as well as NO effects upon osteoblasts and osteoclasts have been summarized. Several studies indicate that NO deficiency might be implicated in various vascular diseases observed in post-menopausal women. Other works also indicate that NO deficiency induced by cessation of ovarian activity might be responsible for osteopenia associated with this condition. Thus, decreased production of NO would be responsible both for post-menopausal osteoporosis as well as for osteopenia sometimes observed in amenorrheic athletes. Moreover osteoblastic response to mechanical stimulation might implicate estrogenic receptor(s). The role of these receptors in the regulation of NO synthesis is still unknown.     

EEG mapping investigations of psychomotor and music perception brain dysfunction in untreated schizophrenic patients

Twenty-six untreated schizophrenic inpatients and 34 control persons were investigated using 16-channel EEG mapping during resting, manumotor and music perception tasks. Power values of activation tasks were each referenced to a separate, immediately preceding resting condition, using conventional delta, theta, alpha and 2 beta frequency bands. Results in delta and alpha bands, which maximally separated the two groups, are reported only for space reasons. Results indicated a “nonreactivity” (in all frequency bands) on the two activation paradigms in schizophrenic patients as a group. Major gender effects were obtained in normal persons, but not signs of nonreactivity comparable to patients. Subdividing patients exclusively by means of their EEG changes on activation produced meaningful clinical subgroups of “positive/negative” schizophrenics. This latter finding could contribute towards clinical utility of EEG mapping in psychiatry.

Résumé

Vingt-six malades schizophrènes non traités par des médicaments étaient étudiés par l'EEG topographique à 16 voies pendant des tâches psychomotrices et de la perception musicale. Ils étaient comparés à 34 personnes contrôles. Les valeurs de la puissance étaient calculées dans les états de repos et d'activation dans les bandes de fréquences (conventionnelles) delta, theta, alpha et bêta 1 et 2. Seules les bandes delta et alpha, qui séparaient au maximum les deux groupes, sont montrées dans l'article en raison de l'espace. Tandis que les sujets normaux montraient des changements majeurs de l'EEG pendant les deux types de tâches — modifié par le sexe, les malades schizophrènes montraient au contraire des signes de « non-réactivité . L'essai de grouper les malades exclusivement par leurs changements de l'EEG pendant l'activation cérébrale qu'effectuait un groupe était cliniquement significative, en séparant les malades portant des symptomes « positivesde ceux avec des symptomes « négatives . Le résultat final pourrait indiquer une valeur clinique de l'EEG quantifié pour la psychiatrie.
