Unusual (self-)injuries in a case of hanging

A 41-year-old man was found by his wife in an atypical hanging situation in their apartment. As there was a known previous psychiatric illness and a history of suicide attempts, the investigative authorities assumed this case was a suicide. However, the autopsy revealed numerous findings that are unusual for a suicidal atypical hanging, including numerous cuts on the face, the arms and the penis. According to his wife, the deceased suffered from Asperger's syndrome with auto-aggressive behavior. He had allegedly injured himself with household scissors in the days before his death and had hit himself numerous times in the face the night before his death. His wife also revealed that she would injure him with scissors at his request. Even though the observed injury pattern in this case contradicted a self-infliction, the information given by the wife about the chronology of the occurrence of injuries could be reconciled with the findings of the immunohistochemical estimation of wound age. The circumstances that led to the hanging remained unresolved.

Narrative Exposure Therapy in Patients With Posttraumatic Stress Disorder and Borderline Personality Disorder in a Naturalistic Residential Setting: A Randomized Controlled Trial

Background: Comorbid Posttraumatic Stress Disorder (PTSD) increases the already high symptom burden of patients with Borderline Personality Disorder (BPD). As the gold standard for BPD treatment, Dialectical Behavior Therapy (DBT), does not focus on PTSD, other treatment approaches are needed. Narrative Exposure Therapy (NET) was designed to address multiple traumatic events and may be especially useful in this patient group. The aim of the present study was to determine the efficacy of NET compared to DBT based treatment (DBT-bt) in a randomized controlled trial. Methods: Female patients (n = 60) with BPD and comorbid PTSD were randomized to either a 10-week residential NET or DBT-bt. The primary outcome was change in PTSD severity as assessed by the Clinician Administered PTSD Scale (CAPS). Mixed linear models as well as reliable change, remission, and response rates were used to compare improvement across treatment groups. Results: Mixed linear model showed that patients in both treatments improved significantly over time across all outcome measures. This improvement was not more pronounced in NET (no significant time × type of treatment effect). However, NET resulted in a higher remission rate as compared to DBT-bt. PTSD remission was accompanied by BPD remission in all cases. Conclusions: This study shows the value of trauma-focused therapy in patients with BPD and PTSD for recovery in both disorders. To shorten the duration of both illnesses as much as possible, future studies should focus on the factors predicting treatment success and enabling patients to benefit from trauma-focused treatment as soon as possible.

Genome-wide association study of borderline personality disorder reveals genetic overlap with bipolar disorder, major depression and schizophrenia

Borderline personality disorder (BOR) is determined by environmental and genetic factors, and characterized by affective instability and impulsivity, diagnostic symptoms also observed in manic phases of bipolar disorder (BIP). Up to 20% of BIP patients show comorbidity with BOR. This report describes the first case-control genome-wide association study (GWAS) of BOR, performed in one of the largest BOR patient samples worldwide. The focus of our analysis was (i) to detect genes and gene sets involved in BOR and (ii) to investigate the genetic overlap with BIP. As there is considerable genetic overlap between BIP, major depression (MDD) and schizophrenia (SCZ) and a high comorbidity of BOR and MDD, we also analyzed the genetic overlap of BOR with SCZ and MDD. GWAS, gene-based tests and gene-set analyses were performed in 998 BOR patients and 1545 controls. Linkage disequilibrium score regression was used to detect the genetic overlap between BOR and these disorders. Single marker analysis revealed no significant association after correction for multiple testing. Gene-based analysis yielded two significant genes: DPYD (P=4.42 × 10-7) and PKP4 (P=8.67 × 10-7); and gene-set analysis yielded a significant finding for exocytosis (GO:0006887, PFDR=0.019; FDR, false discovery rate). Prior studies have implicated DPYD, PKP4 and exocytosis in BIP and SCZ. The most notable finding of the present study was the genetic overlap of BOR with BIP (rg=0.28 [P=2.99 × 10-3]), SCZ (rg=0.34 [P=4.37 × 10-5]) and MDD (rg=0.57 [P=1.04 × 10-3]). We believe our study is the first to demonstrate that BOR overlaps with BIP, MDD and SCZ on the genetic level. Whether this is confined to transdiagnostic clinical symptoms should be examined in future studies.

Relationship between transitional objects and personality disorders in female psychiatric inpatients: a prospective study

Patients often bring transitional objects (TO) to inpatient units. The authors quantified the frequency of TO possession in an inpatient psychiatric setting and assessed whether TO use is specific to a personality disorder (PD) diagnosis, focusing on borderline PD (BPD). TO possession was assessed using the Transitional Objects Questionnaire, and PD diagnosis was established using standard DSM-IV clinical interviews. Of the 104 female patients assessed, 57.7% showed TO use; 84% of BPD patients, 71% of BPD-trait patients, 65% of patients with PD traits (other than BPD), and 56% of PD patients (other than BPD) displayed TO use, whereas 30.6% of patients without PD showed TO use. Patients with TOs were significantly younger and had significantly longer hospital stays. The specificity and sensitivity for TO use in the BPD group were 0.506 and 0.84, respectively. The authors conclude that TO use is closely related to PD diagnosis, but is not specific to BPD.

Personality organization in borderline patients with a history of suicide attempts

Suicide attempts (SA) are common in patients with Borderline Personality Disorder (BPD). Recent studies focus on aspects of personality associated with risk for SA such as deficits in affect regulation including impulse control and aggression. The current study examines associations of dysfunctional personality organization, psychiatric comorbidities as well as non-suicidal self-injury (NSSI) with SA in a sample of 68 BPD outpatients. Patients with a history of SA yielded higher scores in personality domains of aggression, especially self-directed aggression. Further, a history of SA was associated with a worse general level of personality organization and a higher prevalence rate of NSSI and substance abuse disorder. The results demonstrate that SA in BPD patients might be regarded as a manifestation of impaired personality functioning rather than mere state variables and symptoms. Moreover, these findings might have implications for indication, treatment, and prognosis of Borderline Personality Disorder.

[Non-suicidal self-injury as autonomous diagnosis - implications for research and clinic of the DSM-5 proposal to establish the diagnosis of Non-Suicidal Self-Injury in adolescents]

In both classificatory systems DSM-IV and ICD-10 self-injury is a symptom of borderline personality disorder (BPD). But it has been shown empirically that self-injury can also occur independent of BPD, for example, as a component of depressive states or even in adolescents without classifiable psychopathology. The scientific discussion about future diagnostic criteria recently led to a proposal to include Non-Suicidal Self-Injury as an independent disorder in the upcoming DSM-5 classification system. Based on recent epidemiological studies of adolescents in Germany, one may assume that approximately 4% of all youths in middle to late adolescence would fulfill the prevalence criterion (criterion A) of the proposed DSM-5 disorder (that is, at least five self-injury incidents within the previous 12 months). A precise classification of Non-Suicidal Self-Injury based on empirical research is needed to further the research, treatment, and prevention of this diagnosis.

[Nonsuicidal self-injury in adolescence]

Nonsuicidal self-injury (NSSI) usually starts in adolescence. International studies report prevalence rates between 3 and 37% (for Germany between 15 and 26%) in adolescents. From a neurobiological perspective, there is evidence that primarily the serotonergic system is involved in the origin and maintenance of this behaviour. NSSI is often used by adolescents to influence aversive affective states, but sometimes serves other functions as well, such as self-punishment or anti-dissociation. To date there are many assessment instruments, some of which are available in a German translation. Regarding psychotherapeutic interventions there is evidence for a good efficacy of dialectical behavioral therapy for adolescents (DBT-A). There is little evidence for psychopharmacological interventions in childhood and adolescence; thus treatment should focus on psychotherapeutic interventions.

Cognitive processes in dissociation: comment on Giesbrecht et al. (2008)

In their recent review "Cognitive Processes in Dissociation: An Analysis of Core Theoretical Assumptions," published in Psychological Bulletin, Giesbrecht, Lynn, Lilienfeld, and Merckelbach have challenged the widely accepted trauma theory of dissociation, which holds that dissociative symptoms are caused by traumatic stress. In doing so, the authors have outlined a series of links between various constructs--such as fantasy proneness, cognitive failures, absorption, suggestibility, altered information-processing, dissociation, and amnesia--claiming that these linkages lead to the false conclusion that trauma causes dissociation. A review of the literature, however, shows that these are not necessarily related constructs. Careful examination of their arguments reveals no basis for the conclusion that there is no association between trauma and dissociation. The current comment offers a critical review and rebuttal of Giesbrecht et al.'s argument that there is no relationship between trauma and dissociation.

[The crisis of the operational diagnostic approach in psychiatry]

Based on historical and current contributions, the operational diagnostic approach is examined from a psychopathological point of view. Operational diagnostic systems in psychiatry are characterised by an atomising approach. In this context, psychopathological symptoms are interpreted as elementary entities which can be combined into a specific diagnostic category. Many years before operational diagnostic systems were introduced into psychiatry, however, such an atomising procedure was criticised by authors like Karl Jaspers, Willy Mayer-Gross or Klaus Conrad. Furthermore, validation of diagnostic criteria of operational diagnostic systems has not succeeded so far using biological findings or results of family and follow-up studies. This may be one reason for the fact that categorical approaches in psychiatric diagnosis are questioned increasingly and dimensional diagnostic models are suggested.
