Isolation and characterization of the [Ga2Al18O8(OH)36(H2O)12](8+) cluster: cationic variations on the Wells-Dawson topology

The structural chemistry of Group 13 polyoxometalates lags far behind related negatively charged transition metal species and limits the development of advanced materials. A novel heterometallic cluster [Ga2Al18O8(OH)36(H2O)12](8+) (Ga2Al18) has been isolated using a supramolecular approach and structurally characterized using single-crystal X-ray diffraction. Ga2Al18 represents the Wells-Dawson structure polycations and variations in the structural topology may be related to the initial stabilization of the Keggin isomer. DFT calculations on the related ε-Keggins (GaAl12 and Al13), Ga2Al18, and theoretical Al2Al18 clusters reveal similar features of electronic structure, suggesting additional heteroatom substitution in other isostructural clusters should be possible.

A single approach to the recovery of DNA and firearm discharge residue evidence

The Laboratory of the Strathclyde Police Forensic Support Department extracts DNA from cellular material recovered from garments submitted as evidence. The standard method used an adhesive tape attached to a plastic or acetate support. This paper demonstrates a method whereby a single sample, recovered from clothing, can be examined for Firearm Discharge Residue and then extracted for DNA.

Artefactual skin disease in children and adolescents

As in adults, artefactual skin disease in children and adolescents has heterogenous presentations with multifactorial aetiology. We report a series of 32 young patients aged 8-16 years. There were 24 females and 8 males. In over half of the cases the lesions were on the head and neck. The types of lesions encountered included physical injury producing grazing, erosions and deep ulcers, chemical and thermal burns, hair cutting and shaving and skin painting. We discuss the approach that we believe should be taken with these patients, emphasizing the role of dermatology-psychiatry liaison in their management. Of great importance is the avoidance of confrontation of the patient but the clear exposition of the nature of the problem to the parents. The major aim should be to have the family accept the need for expert psychiatric assistance.

Ethical relationships in paediatric emergency medicine: moving beyond the dyad

Most areas of health-services research concentrate on a dyadic relationship between doctor and patient. In paediatric emergency medicine it may be necessary to focus on a more complicated relationship because the parents of the child play an important role in the delivery of medical services. This paper discusses the ethical principles in paediatric emergency medicine from the perspective of five disciplines: health economics, paediatrics, medical ethics, law and mental health. The general consensus is that the traditional dyadic model is inadequate and that a more complicated relationship is needed for the paediatric emergency setting, such as triadic, multiple-dyadic or polyadic. Such models allow the inclusion of the parents and possibly other family members, medical providers and community members. If the paediatric setting is considered in such a framework, it may be possible to deliver a more socially beneficial medical service.

A child and adolescent psychiatric outreach service for rural New South Wales: a telemedicine pilot study

OBJECTIVE

To examine the feasibility of a tertiary outreach service in child and adolescent psychiatry to two rural health centres in New South Wales, Australia.

METHODS

Following a site visit to Dubbo Hospital and Bourke Hospital, telemedical videoconferencing was provided for 2 h/week for 32 weeks. Details of referrers, patients' diagnosis and outcome, and satisfaction with the service were obtained.

RESULTS

Cases were triaged by a nominated rural adolescent mental health worker. The service provided detailed assessment and management of servere, complex, mental and neuropsychiatric disorders. Fifty-four young people were assessed and 72 joint consultative videoconferencing interviews were undertaken, including 26 initial consultations. Twenty-three initial consultations were undertaken on the visit to the rural centres. Clinical descriptions illustrate the flexibility and sensitivity of the service.

CONCLUSION

Telepsychiatry provides access to a flexible, effective tertiary service for those with special, complex needs, including the disadvantaged or isolated. It makes a valuable economic contribution to supporting and educating rural health professionals, thereby enriching rural mental health services.

A study of independence between STR and conventional blood type loci

Blood samples from approximately 200 Scottish Caucasian individuals were typed at conventional loci (PGM, Gc and EAP) and also with a four locus STR multiplex. Tests of the data are described which demonstrate that the assumptions of between locus independence are robust for use in forensic casework.

Validation of a frequency database for four STR loci for use in casework in the Strathclyde Police Forensic Science Laboratory

Data for four STR loci have been collected from 400 samples taken from complainers and suspects encountered in casework at the Strathclyde Police Forensic Science Laboratory (SPFSL). This paper describes statistical testing which demonstrates that its use will provide operationally robust procedures. Comparisons made with data collected from other British samples confirmed no practical differences between the different frequency distributions. This work provides further confirmation of the reliability of the so-called "product rule' in estimating the frequency of multilocus genotypes in British forensic casework.

Multiple personality disorder in an intellectually disabled man: a case report

The case of a young man with the dual diagnoses of severe intellectual handicap (IQ 30 and mental age 4 years) and Multiple Personality Disorder is presented. The intellectual handicap is probably due to hypoxia in infancy and the Multiple Personality Disorder follows prolonged physical and sexual abuse. The patient frequently switches between any of nine discrete but incompletely formed identities. Although some personalities seem more capable than others, all have similar levels of disability on testing. The diagnosis of psychiatric disorders coexistent with the intellectual handicap is hindered by the difficulty in separating psychiatric phenomena from the behavioural disturbances associated with the disability. Differential diagnosis and management are discussed.

Clinical features of conversion disorder

This study reviewed the case notes of 52 children diagnosed as suffering from hysterical conversion during admission to a paediatric teaching hospital over a 10 year period. The disorder was rare below 8 years of age and girls outnumbered boys three to one. Altogether 75% of the children presented during spring and summer; at the time of end of year exams and the beginning of the new school year. The presentation was usually polysymptomatic with gait disturbance being the main complaint in 36 children. Sensory abnormality, predominantly pain, was present in 40 children; this indicates a strong association between psychogenic pain and conversion disorder in children. At discharge 32 were completely recovered or had appreciably improved. There was a core group that presented particular difficulties with diagnosis and showed little positive response to treatment.

Psychological and physical morbidity in the aftermath of a cyclone

A Fijian community affected by a cyclone was compared with an unaffected but similar community. Two months after the cyclone both psychological and physical morbidity was 2-3 times greater in the affected community than in controls. By the third month morbidity had resolved to levels similar to those in the unaffected population. Brief, catastrophic stress without loss of life appears to provoke psychological and physical morbidity of relatively brief duration.

Parental representations of schizophrenics and their association with onset and course of schizophrenia

The view that schizophrenics have been exposed to a parental style of low care and overprotection was assessed in a case-control study of 72 schizophrenics using the Parental Bonding Instrument (PBI) which measures perceived parental characteristics. Those who assigned one or both parents to the low care/overprotection group had an earlier age of initial hospitalization, and in nine months following hospital discharge were more likely to be readmitted. The PBI is a simple measure capable of predicting schizophrenic relapse.
