Mutualité de l’autonomie et relation d’objet au Rorschach : mise en perspective du modèle américain et de la conception psychanalytique structurale française

International audienceThe authors present Urist's Mutuality of Autonomy scale (MOA) and a brief report of validation research about it, showing its usefulness in clinical diagnostic and therapeutic field. Their aim is to refine the scale and to match it with a new objet relations representations scale, using French structural psychoanalytic model (Bergeret,1974, 1986). Future researches are suggested for its validation.Les auteurs présentent l'échelle américaine de mutualité d'autonomie d'Urist (1977) et une brève synthèse des travaux de validation montrant son intérêt en clinique diagnostique et thérapeutique. Ils se proposent pour l'affiner de la mettre en correspondance avec une grille d'analyse de la représentation de relations d'objet au Rorschach, élaborée à partir d'une perspective psychanalytique structurale (Bergeret 1974,1986). Des pistes de recherche pour valider cette dernière sont ensuite suggérées

DSM-5, Trouble de personnalité schizotypique et nosographie psychanalytique structurale française

International audienceObjectives: In this article, we present the evolution in the diagnostic criteria in the DSM-5 for schizotypal personality disorder, which is included both in personality disorders and in the new schizophrenia spectrum. The different interpretations (categorical versus fully dimensional) of experiences assimilated to psychosis raise important issues in contemporary approaches to mental health. One major aspect of the problem appears to be the development of the paradoxical notions of “healthy”, “benign” or even “happy” schizotypy. We consider the choice of favouring the dimensional approach, setting this alongside the French structural psychoanalytical nosography, and in particular the definition by Bergeret of the schizophrenic character and the notion of suppléances in Lacanian structural psychoanalytical clinical practice.Method: We reviewed the points in common between the new DSM-5 model and the French structural psychoanalytical model, by way of a comparative study of recent English language publications in the field of schizotypy and some French psychoanalytical clinical studies.Results: The two formerly opposing models have drawn considerably closer, with the acceptation of a dimensional perspective in the DSM-5. The choice of a dimensional rather than a categorical approach has undeniably contributed to reducing the gap between the psychiatric classification and French psychoanalytical nosography. Insofar as the new model for personality disorders – still requiring empirical validation – focuses on personality traits and functioning (assessed not only with regard to the self, but also on interpersonal level, approached via the ability for empathy and intimacy), it relies on far more stable aspects than symptoms alone, and at the same time places them on a continuum from normal to pathological. We consider this amounts to genuine progress in the detection and understanding of psychopathology.Discussion: The DSM-5 can no longer claim to be a-theoretical (despite the long-standing position of its authors). Moreover, the American Psychiatric Association (APA) confirms that the Big Five factorial theory was used to define the field of personality and personality traits. However, the APA forgets to mention the implicit influence of the American psychoanalytical work by Kernberg, published earlier. Indeed the new severity scale for alterations in the functioning of personality in the DSM-5, whether for self or for interpersonal relationships, presents a fair number of similarities with the conceptualisations by Kernberg concerning the degrees of alteration in self and in object relations, established by this author to distinguish levels of severity in different narcissistic pathologies. Nevertheless, we feel that the new options taken up by the APA are curiously contradictory. Although they are closer to the psychoanalytical model in the new conception proposed for personality disorders, they are in some respects surprisingly distant: the paranoia disorder has disappeared and only certain of its indicators are maintained (such as persecutory delusion) in an excessively wide schizophrenia spectrum. This misses the reality of the various levels of dissociation present in psychotic entities, already reported by psychiatric pioneers, like Bleuler and by a large number of contemporary psychoanalytical psychopathologists. These levels are not strictly organised in identical manner on the intrapsychic level, and their clinical symptomatology during decompensation does not take exactly the same form. We suggest that substantially different levels of dissociation, leading to explicitly distinct symptom profiles, provide a spectrum that it would be more legitimate to call “psychosis” rather than “schizophrenia”, whilst maintaining a distinction in the contemporary psychoanalytical model between schizophrenia, paranoid schizophrenia and paranoia.ConclusionThe authors propose a more integrative approach. This would involve symptoms, functioning dimensions and personality traits, by taking into consideration the intrapsychic mechanisms that underpin their expression, despite the difficulties in objectifying these mechanisms. The markers for these mechanisms are linked in particular to the nature of the conflicts experienced by patients, the nature of their distress and dominant defences, as well as their object investment mode and areas of conflict.Objectifs: Nous présentons dans cet article l’évolution des critères diagnostiques du DSM-5 pour le trouble de personnalité schizotypique qui est inclus à la fois dans les troubles de personnalité et dans le nouveau spectre schizophrénique. Les différentes interprétations (catégorielle versus pleinement dimensionnelle) de vécus assimilés à la psychose renvoient à des enjeux importants pour les approches contemporaines de la santé mentale. Un des nœuds du problème semble être le développement des notions paradoxales de schizotypie « saine », « bénigne », voire « joyeuse ». Nous réfléchissons sur l’option prise de privilégier l’approche dimensionnelle, en la mettant en parallèle avec la nosographie psychanalytique structurale française, en particulier avec la définition par Bergeret du caractère schizophrénique et les suppléances dans la clinique psychanalytique structurale lacanienne.Méthode: Nous passons en revue les points communs entre ces modèles à partir d’une étude comparative de publications anglo-saxonnes récentes dans le champ de la schizotypie et de travaux de clinique psychanalytique français.Résultats:Les deux modèles jadis opposés se sont considérablement rapprochés avec l’acceptation dans le DSM-5 d’un point de vue dimensionnel, affirmant l’existence d’un continuum normal/pathologique en matière de fonctionnement et de traits de la personnalité.Discussion: Le DSM-5 ne peut plus se prévaloir d’être a-théorique. L’APA affirme d’ailleurs s’appuyer sur la théorie factorielle du Big Five pour définir domaine et traits de personnalité. Mais l’APA omet de mentionner l’influence implicite des travaux de Kernberg.Conclusion: Les auteurs proposent une approche plus intégrative, en considérant les mécanismes intrapsychiques sous-tendant le fonctionnement même de la personnalité et son expression symptomatique

Electrochemical reactions and ionization processes

Electrochemical or photo-electrochemical reactions in both electrospray ionization and laser desorption ionization are discussed stressing the role of the electrode reaction in influencing the ionization process. In particular, upon application of a high voltage during electrospray ionization, the emitter includes a working electrode, where redox reactions are observed, such as electro-generation of benzoquinone and metal ions. In contrast, the target plate in laser-induced desorption ionization also acts as a photo-electrode, especially when modified with a mesoporous semiconductor. We illustrate here how these electrochemical reactions can be used for tagging purposes, and for oxidative or reductive dissociation reactions

Abus sexuel infantile, genre du bébé, et transmission psychique intergénérationnelle: une approche psychanalytique exploratoire et projective

International audienceThe aim of this article is to present a French psychoanalytic model of how and to what extent the sequellae of sexual abuse by a male during a girl's childhood are transmitted to the next generation, as a function of the gender of the abused mother's children. The authors conducted a qualitative exploratory study based on the longitudinal follow-up of a woman who had two boys and a girl. They focused on the impact of two general sequellae: separation anxiety and negativity-disqualification of the paternal and/or male figures. From the methodological standpoint, they used a clinical interview to assess the mother, and a projective tool, a storytelling test, to assess the child's personality using content analysis. The results confirm both the merits of the theoretical framework and the relevance of the projective methodology for grasping sequellae transmitted to the child. The sequellae turned out to be markedly different for the two baby genders: rejection for the male, overprotection and ghostly encryption for the female. Avenues for using this tool and model in future quantitative, comparative studies are suggested

Antioxidant power measurement in platelet concentrates treated by two pathogen inactivation systems in different blood centres.

The antioxidant power measurement can be useful to validate the execution of the pathogen inactivation treatment of platelet concentrates. The aim of this study is to evaluate the technology on different blood preparations including INTERCEPT and Mirasol treatments that are in routine use in Belgium and Luxemburg. The antioxidant power measurement was tested on 78 apheresis platelet concentrates and 54 pools of buffy-coats-derived platelet concentrates before and after INTERCEPT treatment. In addition, 100 Reveos platelet pools were tested before and after Mirasol treatment. The antioxidant power was quantified electrochemically using disposable devices and was expressed as equivalent ascorbic acid concentration. Mean results for apheresis platelet concentrates were of 90 ± 14 and 35 ± 10 µmol/l eq. ascorbic acid before and after INTERCEPT treatment, respectively. The mean results for pools of buffy-coats-derived platelet concentrates were of 81 ± 10 and 29 ± 4 eq. µmol/l ascorbic acid before and after INTERCEPT treatment, respectively. For buffy-coats-derived platelet concentrates treated by Mirasol technology, the mean results were of 98 ± 11 and 32 ± 10 µmol/l eq. ascorbic acid before and after illumination, respectively. The antioxidant power significantly decreases with pathogen inactivation treatments for platelet concentrates treated by INTERCEPT or Mirasol technologies
