Recurrent self-injurious behavior in forensic patients

Factors influencing the length of stay in forensic psychiatric settings: a systematic review

BACKGROUND

Forensic psychiatry is often associated with long admissions and has a high cost of care. There is little known about factors influencing length of stay (LOS), and no previous systematic review has synthesised the available data. This paper aims to identify factors influencing the LOS in forensic psychiatry hospitals to inform care and interventions that may reduce the length of admissions.

METHODOLOGY

A systematic review was conducted by searching major databases, including PubMed, EMBASE and PsycInfo, from inception until May 2022. Observational studies conducted in forensic hospitals that examined associations between variables of interest and LOS were included. Following data extraction, the Newcastle‒Ottawa Scale was used for quality appraisal. No meta-analysis was conducted due to heterogeneity of information; a quantitative measure to assess the strength of evidence was developed and reported.

RESULTS

A total of 28 studies met the inclusion criteria out of 1606 citations. A detailed quantitative synthesis was performed using robust criteria. Having committed homicide/attempted homicide, a criminal legal status with restrictions, and a diagnosis of schizophrenia-spectrum disorders were all associated with longer LOS. Higher Global Assessment of Functioning (GAF) scores were associated with a shorter LOS.

CONCLUSION

High-quality research examining factors associated with LOS in forensic psychiatry is lacking, and studies are heterogeneous. No modifiable characteristics were identified, and thus, practice recommendations were not made. There is an increasing necessity to understand the factors associated with longer admissions to inform care and increase success in reintegration and rehabilitation. This paper provides recommendations for future research.

Is hyperinsulinemia a possible clinical explanation underlying the myth of Erysichthon?

BACKGROUND

An insulinoma is an endocrine tumor of the pancreas, originating from the beta cells, and has a prevalence of 4 cases per 1 million patients. Insulinomas often follow a "90% rule": 90% are benign [1, 2], 90% originate in the pancreas, 90% are approximately 2 cm wide, and 90% are isolated. Individuals with an insulinoma may have episodic bouts of hyperinsulinemic hypoglycemia. Typically, an insulinoma is indicated by hypoglycemic symptoms which are a result of catecholamine reaction and neuroglycopenia. There is increased secretion of insulin in patients with an insulinoma despite having lower glucose levels.

PURPOSE

This paper examines the myth of Erysichthon and speculates whether the symptoms experienced by him are possibly related to those found in patients with an hyperinsulinoma.

METHODS

The myth of Erysichthon was taken from various sources (i.e. Hesiod, Callimachus, Ovid) and examined. Symptoms of Erysichthon were then examined.

RESULTS

The myth of Erysichthon depicts various sympathoadrenal and neuroglycopenic symptoms including anxiety and abnormal behaviour which can be found in insulinomas. Insulinomas may often present a diagnostic challenge due to their deceptive nature and overlapping symptoms with other disorders such as neurologic disease. Insulinomas inducing weight loss resemble Calamachus's account of Erysichthon whose body is finally emaciated, even though having polyphagia.

CONCLUSION

The myth of Erysichthon provides an interesting range of clinical symptoms which I have argued relate to symptoms found in patients with an insulinoma. Although, insulinomas were unknown in ancient medical lore, this paper has speculated that based on Erysichthon's symptoms, the possibility of an insulinoma cannot be ruled out.

A Case of Self-Cannibalism: An Extremely Rare Type of Self-Mutilation With Multiple Risk Factors

ABSTRACT

Self-mutilation is a behavior often associated with various psychiatric diseases, and it has various risk factors. Self-cannibalism, an extremely rare form of self-mutilation, can also be observed in the absence of psychosis and substance abuse. This study reports a case of self-cannibalism with multiple risk factors including history of substance use, previous self-mutilation actions, suicidal attempts, antisocial personality disorder, imprisonment, and active symptoms associated with untreated schizophrenia.

Toward a re-interpretation of self-harm: A cross-contextual approach

A common view is that self-harmers are individuals who are exposed to or have been exposed to stressors and hostility in everyday settings. A strand of research has also found that self-harmers expose other people to their hostility. Extending these findings, this study examined whether adolescent self-harmers are simultaneously exposed and expose others to hostility in their everyday interpersonal contexts-at home, at school, and during leisure-time. The participants were 1,482 adolescents, ranging from 13 to 16 years of age, who attended different schools in a medium-sized city in central Sweden. The results show that the adolescents involved in mutually hostile relationships in their different interpersonal contexts exhibited higher self-harm than the adolescents who were exposed to others' hostility or exposed other people to their hostility. Also, the more mutually hostile settings the adolescents were involved in, the more self-harm they reported. Overall, our findings suggest not only that self-harmers are exposed to hostility in their different interpersonal contexts, as has been typically assumed, but also that they simultaneously expose others to hostility in these contexts. This has implications for our understanding of young people who harm themselves and also for intervention. Aggr. Behav. 42:522-532, 2016. © 2016 Wiley Periodicals, Inc.

A Population-Based Study of the Prevalence and Correlates of Self-Harm in Juvenile Detention

Background

Suicide is the number one cause of death among incarcerated youth. We examined the demographic and forensic risk factors for self-harm in youth in juvenile detention using a Canadian provincial correctional database.

Method

We analyzed data from de-identified youth aged 12 to 18 at the time of their offense who were in custody in a Manitoba youth correctional facility between January 1, 2005 and December 30, 2010 (N = 5,102). Univariate and multivariate logistic regression analyses determined the association between staff-identified self-harm events in custody and demographic and custodial variables. Time to the event was examined based on the admission date and date of event.

Results

Demographic variables associated with self-harm included female sex, lower educational achievement, older age, and child welfare involvement. Custodial variables associated with self-harm included higher criminal severity profiles, younger age at first incarceration, longer sentence length, disruptive institutional behavior, and a history of attempting escape. Youth identified at entry as being at risk for suicide were more likely to self-harm. Events tended to occur earlier in the custodial admission.

Interpretation

Self-harm events tended to occur within the first 3 months of an admission stay. Youth with more serious offenses and disruptive behaviors were more likely to self-harm. Individuals with problematic custodial profiles were more likely to self-harm. Suicide screening identified youth at risk for self-harm. Strategies to identify and help youth at risk are needed.

People with learning disabilities in a low secure in-patient unit: comparison of offenders and non-offenders

BACKGROUND

People with learning disability who exhibit challenging behaviour are frequently segregated from services and local teams are often reluctant to receive them back into their care. This situation is worse in those whose challenging behaviour includes a forensic history, but the difference between those labelled as challenging and those treated as offenders is not clear, and there is a lack of evidence about treatment effectiveness.

AIMS

To test between-group differences in aggression and treatment outcome in people with learning disability and challenging behaviour, with and without a forensic history.

METHOD

Clinical records of 86 former in-patients (45 offenders and 41 non-offenders) of a specialist unit were compared on measures of behavioural disturbance and placement outcome.

RESULTS

People in the offenders group were significantly less likely to be aggressive to others and to use weapons, but significantly more likely to harm themselves compared with the non-offenders group. Both groups had a significant reduction in their challenging behaviour during admission, and there was no significant difference in treatment outcome.

CONCLUSIONS

The negative reputation of people with learning disabilities who offend needs to be reconsidered.

The motivations for self-injury in psychiatric inpatients

Nonsuicidal self-injurious behavior (SIB) occurs in both culturally appropriate and culturally inappropriate forms. It is one of the diagnostic criteria for borderline personality disorder, but it occurs in several psychiatric and neurological populations. The personal intent of SIB in psychiatric populations is incompletely understood. A self-report scale (Self-Injury Motivation Scale; SIMS) to assess motivation for self-injury was developed. Relationships among motivation for SIB, characteristics of SIB, and psychopathology were explored. A semistructured interview and the SIMS, Dissociative Experiences Scale, Beck Depression Inventory, Davidson Trauma Scale, and Millon Clinical Multiaxial Inventory-II were given to 99 consecutively admitted inpatients. The SIMS had good reliability and validity. A high SIMS score suggested distinct psychopathology. Several factors on the SIMS differentiated motivations for SIB. Patients with different SIMS factor profiles had different psychopathology.
