Long-term and bizarre self-injurious behavior: an approach to underlying psychological mechanisms and management

Deliberate Foreign Body Ingestion in a 35-Year-Old Woman With Borderline Personality Disorder and Several Psychiatric Comorbidities

Deliberate foreign body ingestion (DFBI) is a rare psychopathological disorder that involves the swallowing of non-nutritive objects to cause self-harm. It is most commonly associated with borderline personality disorder (BPD). Very scant literature has been published on the psychopathological understanding or psychopharmacological interventions. Mostly, gastroenterological and surgical management regarding the removal of the foreign body has been discussed in the literature. DFBI can be very challenging in terms of the treatment of the patient and the morale of the health providers - it exhausts the patient and the family and evokes frustration among the medical staff due to its resistance to remission. By presenting the case of a patient in this article, we will discuss what is known about the poorly understood DFBI and the challenges and difficulties encountered while treating these patients. Further, we will discuss how a biopsychosocial approach can be used in treating these patients.

Self-injurious behaviours in rhesus macaques: Potential glial mechanisms

BACKGROUND

Self-injurious behaviour (SIB) can be classified as intentional, direct injuring of body tissue usually without suicidal intent. In its non-suicidal form it is commonly seen as a clinical sign of borderline personality disorder, autism, PTSD, depression, and anxiety affecting a wide range of ages and conditions. In rhesus macaques SIB is most commonly manifested through hair plucking, self-biting, self-hitting, and head banging. SIB in the form of self-biting is observed in approximately 5-15% of individually housed monkeys. Recently, glial cells are becoming recognised as key players in regulating behaviours.

METHOD

The goal of this study was to determine the role of glial activation, including astrocytes, in macaques that had displayed SIB. To this end, we performed immunohistochemistry and next generation sequence of brain tissues from rhesus macaques with SIB.

RESULTS

Our studies showed increased vimentin, but not nestin, expression on astrocytes of macaques displaying SIB. Initial RNA Seq analyses indicate activation of pathways involved in tissue remodelling, neuroinflammation and cAMP signalling.

CONCLUSIONS

Glia are most probably activated in primates with self-injury, and are therefore potential novel targets for therapeutics.

Extreme challenges: psychiatric inpatients with severe self-harming behavior in Norway: a national screening investigation

BACKGROUND

Extreme self-harming behavior is a major challenge for patients and health services. Nevertheless, this patient population is poorly described in research literature.

AIMS

The aim of this study was to assess the volume of patients with extensive psychiatric hospitalization due to extreme self-harming behaviors, the extent of severe medical sequelae, and collaboration problems within health services.

METHODS

In a national screening investigation, department managers in 83 adult psychiatric inpatient institutions across all health regions in Norway were invited to participate in a brief, prepared, telephone interview.

RESULTS

Sixty-one interviews were completed. Extensive hospitalization (prolonged or multiple) due to extreme self-harm was reported for the last year in all health regions and in 427 individual cases. Mean number of cases did not differ by region. Psychiatric hospitalizations were more frequent in hospital units than mental health centers. In 109 of the cases, self-harming behavior had severe medical consequences, including five deaths. In 122 of the cases, substantial collaboration problems within the health services were reported (disagreements on diagnosis, treatment needs and resources). Extensive (long-term) hospitalization was particularly associated with the combination of severe medical sequelae and collaboration problems.

CONCLUSION

This investigation confirms a noteworthy, nationwide, population of severely self-harming inpatients with extensive health service use, prevalent severe medical complications, and unsatisfactory collaboration within health services. These preliminary results are alarming, and indicate a need for more profound understanding of highly complex and severe cases.
