A transdisciplinary approach to adolescent forensic mental health

Objective: To examine new strategies which may be implemented to address the significant mental health and substance abuse problems of young people within the juvenile justice system. Method: Wide-ranging literature review of mental health problems within the juvenile justice population is given, illustrating the high prevalence of mental health problems within this cohort of young people. Reference is made to the differing demographics and agendas of the American justice system compared to that found in Australia. Results: It is suggested that new initiatives stemming from quality Australian studies are required in order to facilitate reform within adolescent forensic mental health. Psychiatrists need to be at the forefront of innovative policy delivery within the juvenile justice system. Conclusions: A transdisciplinary approach is required to meet the changing needs of young people within the juvenile justice system. Such a system of care recognizes that these young people and their families have multiple needs that cross traditional boundaries and a collaborative approach across agencies is essential at both the policy and practical level. Psychiatrists have an important role to play in the development of these services. A systemic process to address such needs is offered.

Neuroplasticity and psychiatry

Objective: There is increasing concern that the course of psychiatric disorders may be affected by parameters such as the duration and intensity of symptoms of initial episodes of illness. As this indicates that abnormal function produces long-term changes within the brain, a review of the neuroscience literature regarding neuroplasticity is warranted. Method: This article is a selective review, focusing in particular on results obtained from physiological experiments assessing plasticity within the mammalian neocortex. The possible relevance of results to psychiatry is discussed. Results: While the most dramatic examples of neuroplasticity occur during a critical period of neural development, neuroplasticity can also occur in adult neocortex. Neuroplasticity appears to be activity-dependent: synaptic pathways that are intensively used may become strengthened, and conversely, there may be depression of transmission in infrequently used pathways. Conclusions: Results from neurophysiological experiments fend support to the clinical observation that the intensity and duration of a psychiatric disorder may adversely alter its long-term course. Rapid aggressive treatment may prevent this from occurring. While pharmacotherapy may reduce the duration and severity of symptoms, it may also have an independent, as yet unknown, effect on neuroplasticity.

Hair morphine concentrations of fatal heroin overdose cases and living heroin users

Aims To compare heroin and other opiate use of heroin overdose fatalities, current street heroin users and drug-free therapeutic community clients. Design Hair morphine concentrations that assess heroin use and other opiate use in the 2 months preceding interview or death were compared between heroin overdose fatalities diagnosed by forensic pathologists (fOD) (n = 42), current street heroin users (CU) (n = 100) and presumably abstinent heroin users in a drug-free therapeutic community (TC) (n = 50). Setting Sydney, Australia. Findings The mean age and gender breakdown of the three samples were 32.3 years, 83% male (FOD), 28.7 years, 58% male (CU) and 28.6 years, 60% male (TC). The median blood morphine concentration among the FOD cases was 0.35 mg/l, and 82% also had other drugs detected. There were large differences between the three groups in hair morphine concentrations, with the CU group (2.10 ng/mg) having concentration approximately four times that of the FOD group (0.53 ng/mg), which in turn had a concentration approximately six times that of the TC group (0.09 ng/mg). There were no significant differences between males and females in hair concentrations within any of the groups. Hair morphine concentrations were correlated significantly with blood morphine concentrations among FOD cases (r = 0.54), and self-reported heroin use among living participants (r = 0.57). Conclusions The results indicate that fatal cases had a lower degree of chronic opiate intake than the active street users, but they were not abstinent during this period.

Attitudes toward psychiatry among students entering medical school

Objective: To survey the attitudes of Australian medical students to determine their views about the relative attractiveness of psychiatry as a career compared with other specialities, and against findings from a North American study. Method: We surveyed 655 first-year medical students attending six Australian Universities. Results: Responses indicated that Australian medical students view psychiatry as distinctly less 'attractive' than other career options, as reported in the North American sample. In comparison with other disciplines, psychiatry was regarded as more interesting and intellectually challenging, but also as lacking a scientific foundation, not being enjoyable and failing to draw on training experiences. Conclusion: Our findings suggest that psychiatry has an image problem that is widespread, reflecting Community perceptions and the specialist interests of medical students on recruitment. If psychiatry is to improve its 'attractiveness' as a career option, identified image problems need to be corrected and medical student selection processes re-considered.

Vocational rehabilitation in psychiatry: A re-evaluation

Objective: To highlight the vocational gap in the provision of psychiatric rehabilitation, to outline the goals and conceptual framework of psychiatric rehabilitation, and to discuss rehabilitation interventions with specific reference to vocational rehabilitation and the evidence base for supported employment. Conclusions and service implications: Vocational psychiatric rehabilitation has been a neglected area of practice in Australian psychiatry. Psychiatric treatment needs to adopt a more balanced approach in the provision of a range of services, including vocational rehabilitation, in order to improve long-term outcomes for people suffering from psychiatric disability. A vocational focus should be included in psychiatric rehabilitation and better integration between mental health services and vocational services needs to take place. Supported employment is an evidence-based practice that is designed to help people with psychiatric disabilities participate as much as possible in the competitive job market.

Recommendations for animal DNA forensic and identity testing

Genetic analysis in animals has been used for many applications, such as kinship analysis, for determining the sire of an offspring when a female has been exposed to multiple males, determining parentage when an animal switches offspring with another dam, extended lineage reconstruction, estimating inbreeding, identification in breed registries, and speciation. It now also is being used increasingly to characterize animal materials in forensic cases. As such, it is important to operate under a set of minimum guidelines that assures that all service providers have a template to follow for quality practices. None have been delineated for animal genetic identity testing. Based on the model for human DNA forensic analyses, a basic discussion of the issues and guidelines is provided for animal testing to include analytical practices, data evaluation, nomenclature, allele designation, statistics, validation, proficiency testing, lineage markers, casework files, and reporting. These should provide a basis for professional societies and/or working groups to establish more formalized recommendations.

A preliminary case series on the use of quetiapine for posttraumatic stress disorder in juveniles within a youth detention center

Juveniles within the youth justice system have high rates of psychiatric morbidity, including posttraumatic stress disorder (PTSD). This case series describes 6 young people aged 15 to 17 years within a youth detention center who met the criteria for PTSD and reported an improvement in symptoms after 6 weeks of treatment with low-dose quetiapine. The primary outcome measure used was the Traumatic Symptom Checklist in Children. The dose of quetiapine ranged from 50 to 200 mg/d; T scores for PTSD symptoms decreased from 75 (SD, +/- 5.2; range, 68-82) to 54 (SD: +/- 7.4; range, 43-62) (P <= 0.01). Significant improvements in symptoms of dissociation (P <= 0.01), anxiety (P < 0.01), depression (P < 0.01).. and anger (P < 0.05) were also noted over the 6-week evaluation period. Low-dose quetiapine was tolerated well, with no persisting side effects or adverse events. Nighttime sedation was reported, although this was viewed as beneficial. All young people opted to continue with treatment after the assessment period. This preliminary case series suggests that juveniles in detention who have PTSD may benefit from treatment with quetiapine. Caution is needed in interpreting these findings. Both larger open-label and blinded trials are war-ranted to define the use of quetiapine in the treatment of PTSD in the adolescent forensic population.

Public and private psychiatry: Can they work together and is it worth the effort?

Objective: Partnerships in mental health care, particularly between public and private psychiatric services, are being increasingly recognized as important for optimizing patient management and the efficient organization of services. However, public sector mental health services and private psychiatrists do not always work well together and there seem to be a number of barriers to effective collaboration. This study set out to investigate the extent of collaborative 'shared care' arrangements between a public mental health service and private psychiatrists practising nearby. It also examined possible barriers to collaboration and some possible solutions to the identified problems. Method: A questionnaire examining the above factors was sent to all public sector mental health clinicians and all private psychiatrists in the area. Results: One hundred and five of the 154 (68.2%) public sector clinicians and 103 of the 194 (53.1%) private psychiatrists returned surveys. The main barriers to successful collaboration identified by members of both sectors were: 'Difficulty communicating' endorsed by 71.4% of public clinicians and 72% of private psychiatrists, 'Confusion of roles and responsibilities' endorsed by 62.9% and 66%, respectively, and 'Different treatment approach' by 47.6% and 45.6%, respectively. Over 60% of private psychiatrists identified problems with access to the public system as a barrier to successful shared care arrangements. It also emerged, as hypothesized, that the public and private systems tend to manage different patient populations and that public clinicians in particular are not fully aware of the private psychiatrists' range of expertise. This would result in fewer referrals for shared care across the sectors. Conclusions: A number of barriers to public sector clinicians and private psychiatrists collaborating in shared care arrangements were identified. The two groups surveyed identified similar barriers. Some of these can potentially be addressed by changes to service systems. Others require cultural shifts in both sectors. Improved communications including more opportunities for formal and informal meetings between people working in the two sectors would be likely to improve the understanding of the complementary sector's perspective and practice. Further changes would be expected to require careful work between the sectors on training, employment and practice protocols and initiatives, to allow better use of the existing services and resources.
