Borderline personality disorders account for 50% of adolescent hospitalization cases in psychiatry. The severity and psychopathological complexity of these symptoms indicate the need for inclusive models of understanding. Adopting a holistic approach allows for the consideration of not only the patient's environment, but also their position within that environment and their life history.

Anorexia nervosa is a psychiatric disorder that mainly affects women (sex ratio 1/10) and for which the prognosis remains poor (10% of deaths and high risk of chronicity). This disorder is associated with a risk of infertility explained by different physiopathological pathways. Thus, the clinical and subclinical forms of this disease may be over-represented in populations of women using medically assisted reproduction technologies.

Background: Literature data about emotion perception in patients with borderline personality disorders (BPD) revealed some discrepancies between some patients that are vigilant and accurate to detect their emotional environment and others that are impaired at identifying emotions of others. Even if some links between childhood adversity and facial affect recognition have been established, there is a need to understand the heterogeneous psychobiological mechanisms underlying this association. The aim is to distinguish in a BPD sample, the links between facial emotion recognition (FER) and adversity types (maltreatment and parental bonding), by evaluating two dimensions of disengaged and controlling environment.

Background: Randomized controlled trials showed the efficacy of family therapy for anorexia nervosa during adolescence, but studies examining its long-term beneficial effect are still needed. This article presents the results of a 54-month post-randomization follow-up of a previously reported randomized controlled trial that compared two post-hospitalization outpatient treatment programs: Treatment As Usual alone versus Systemic Family Therapy added to Treatment As Usual.

Methods: A consecutive series of 60 female adolescents with anorexia nervosa (DSM-IV) were randomized (30 per group).

The epidemiology of adolescent psychiatric disorders and the relational complexity of their management make exposure to adolescent psychiatry essential during medical school. However, some clinical particularities can complicate the students' learning experiences. Our work aimed to explore the experience of being a medical student during clerkships in adolescent psychiatry.

Although previous cross-sectional studies suggested significantly dysregulated immune response in alexithymia, there is a lack of longitudinal studies. We sought to determine the reliability of the reported relationship between alexithymia and decreased immune response in a longitudinal study. Thirty-eight healthy women who had participated in a cross-sectional study were recontacted 1-year later.

Malgré l'enjeu majeur de santé publique qu'elles représentent, les maltraitances infantiles, et particulièrement les négligences, restent sous-estimées en psychiatrie, tant dans leur prévalence que leur impact sur la santé. De plus, le phénomène de maltraitance reste habituellement associé à un fort déterminisme socio-culturel et est très peu évalué dans les catégories sociales aisées. Cette étude mesure la prévalence et l'impact sur l'état médical des facteurs d'adversité précoce - maltraitances (abus et négligences) et événements de vie (divorce, séparations précoces, antécédents familiaux de maladie psychiatrique) - dans une population d'adolescents hospitalisés en psychiatrie et issus de milieux aisés, afin d'en évaluer l'ampleur et l'impact.

Borderline personality disorder (BPD) in adolescents is characterized by emotional dysregulation, insecure attachment, a history of stressful life events (SLEs) as well as dysfunctional parent-child interactions. The respective contribution of each of these factors on BPD affective symptoms is not yet clear. The purpose of this study is to assess the distinct impact of parental adversity and SLEs on BPD affective symptoms and the role of attachment and alexithymia in such emotional processes.

In adolescent psychiatry, when patients present high-risk sexual behaviours, analysing the symptoms usually leads back to a traumatic sexual event in childhood. These clinical situations include a first stage in which the trauma is constituted and a second adolescent stage in which the mnemic trace can lead to the traumatic experience being reproduced within a destructured psychic apparatus that is seeking restructuration through actions. These two psychopathological stages are examined in the light of the connection between Freud's two paradigms of the and the theory of fantasy, focusing therapeutically either on the primacy of sexual abuse or on the psychic representation of a traumatic sexuality, respectively.

Objective: Among medically assisted procreation (MAP) patients, the prevalence of eating disorders (ED), clinical or subclinical, current or past, is considerable. In addition to metabolic repercussions, the literature suggests that these patients present with more sexual dysfunction, leading to anxiety. This quantitative research on a population of women consulting a MAP department for unexplained or ovulatory infertility proposed to study the sexuality of this population by comparing the sexuality of patients suffering from or having suffered from an ED to the sexuality of the non-ED group.

The authors begin by presenting the epistemological foundations that enabled them to design a therapeutic mediation framework aimed at enhancing the treatment of hospitalized anorexic patients. This unique framework utilizes bodily exploration through sound and music vibration. The authors were inspired by a method of of the body image through clay modeling, created by Gisela Pankow, and by the bodily aspects of the subject's relationship with the object in transitional phenomena and in playing, as elaborated by Donald W.

Purpose: Despite the emergence of a growing qualitative literature about the personal recovery process in mental disorders, this topic remains little understood in anorexia nervosa (AN), especially severe AN during adolescence. This cases series is a first step that aims to understand recovery after severe AN among adolescents in France, from a first-person perspective.

Methods: This cases series applied the interpretative phenomenological analysis (IPA) method to data collected in semi-structured face-to-face interviews about the recovery process of five young women who had been hospitalized with severe AN 10 years earlier during adolescence.

Background: Anorexia nervosa (AN) is a serious psychiatric illness that begins most of the time during adolescence. An early and efficacious intervention is crucial to minimize the risk of the illness becoming chronic and to limit the occurrence of comorbidities. There is a global consensus on optimal treatment for adolescents suffering from AN: international guidelines recommend single-family therapy that involves the patient and his/her family.
