The results of two independent surveys of professionals working in government-funded adult community mental health services were examined with a view to considering how psychologists rate their capacities as mental health case managers. Professional competency and personal efficacy self-report profiles for psychologists were compared with those of other professionals in related roles. The results obtained suggested that psychologists identified their strengths as being in traditional practice roles as individual clinicians. Relative to other professions, psychologists reported weaknesses in team and community-focused practice roles. The implications for professional practice and training are discussed.

In this paper we use sensor-annotated abstraction hierarchies (Reising & Sanderson, 1996, 2002a,b) to show that unless appropriately instrumented, configural displays designed according to the principles of ecological interface design (EID) might be vulnerable to misinterpretation when sensors become unreliable or are unavailable. Building on foundations established in Reising and Sanderson (2002a) we use a pasteurization process control example to show how sensor-annotated AHs help the analyst determine the impact of different instrumentation engineering policies on a configural display that is part of an ecological interface. Our analyses suggest that configural displays showing higher-order properties of a system are especially vulnerable under some conservative instrumentation configurations. However, sensor-annotated AHs can be used to indicate where corrective instrumentation might be placed. We argue that if EID is to be effectively employed in the design of displays for complex systems, then the information needs of the human operator need to be considered while instrumentation requirements are being formulated. Rasmussen's abstraction hierarchy-and particularly its extension to the analysis of information captured by sensors and derived from sensors-may therefore be a useful adjunct to up-stream instrumentation design.

Significance of the decision in McCabe v British American Tobacco Australia Services Ltd - ramifications for the possibilities for success of future litigation of this nature in Australia and overseas - ethical and public policy issues regarding the duties of lawyers to the courts and to their clients - whilst a lawyer's implication in the destruction of documents to prevent a fair trial ultimately involves stricter duties, it exposes a need for vigilance against the possibilities for corporations to act outside the public interest, if not the justice system.

This study assessed the impact of a randomized trial of nursing-based case management for patients with chronic obstructive pulmonary disease, their caregivers, and nursing and medical staff. Sixty-six patients were matched by FEV1 on admission to hospital, and randomized into an intervention or control group. Intervention group patients reported significantly less anxiety at 1 month postdischarge; however, this effect was not sustained. There was little difference between groups in terms of unplanned readmissions, depression, symptoms, support, and subjective well being. Interviews with patients and caregivers found that the case management improved access to resources and staff-patient communication. Interviews with nursing and medical staff found that case management improved communication between staff and enhanced patient care.

Objective: To describe new measures of risk from case-control and cohort studies, which are simple to understand and relate to numbers of the population at risk. Design: Theoretical development of new measures of risk. Setting: Review of literature and previously described measures. Main results: The new measures are: (1) the population impact number (PIN), the number of those in the whole population among whom one case is attributable to the exposure or risk factor (this is equivalent to the reciprocal of the population attributable risk),- (2) the case impact number (CIN) the number of people with the disease or outcome for whom one case will be attributable to the exposure or risk factor (this is equivalent to the reciprocal of the population attributable fraction); (3) the exposure impact number (EIN) the number of people with the exposure among whom one excess case is attributable to the exposure (this is equivalent to the reciprocal of the attributable risk); (4) the exposed cases impact number (ECIN) the number of exposed cases among whom one case is attributable to the exposure (this is equivalent to the reciprocal of the aetiological fraction). The impact number reflects the number of people in each population (the whole population, the cases, all those exposed, and the exposed cases) among whom one case is attributable to the particular risk factor. Conclusions: These new measures should help communicate the impact on a population, of estimates of risk derived from cohort or case-control studies.

We report a case of a patient with the triad of retinoblastoma, dysplastic naevus syndrome (DNS) and multiple cutaneous melanomas. The combination of retinoblastoma and DNS is a significant risk factor for the development of cutaneous melanoma. This risk extends to family members. We recommend that survivors of (inherited) retinoblastoma and their relatives are closely screened for the presence of dysplastic naevi. (C) 2002 Lippincott Williams Wilkins.

Objectives: To identify general practitioners' views on the barriers to using case conferencing (as outlined in the Medical Benefits Schedule (MBS) Enhanced Primary Care package) and to develop a set of principles to encourage greater GP participation in case conferences. Design: Qualitative study, involving semistructured questions administered to focus groups of GPs, conducted between April and July 2001 as part of a broader study of case coordination in palliative care. Participants: 29 GPs from urban, regional, and rural areas of Queensland. Principal findings: Many of the GPs' work practices militated against participation in traditionally structured case conferences. GPs thought the range of MBS item numbers should be expanded to cover alternative methods of liaison (eg, phone consultations with other service providers). The onerous bureaucratic processes required to claim reimbursement were an additional disincentive. Conclusions: GPs would probably be more likely to participate in case conferences if they were initiated by specialist services and arranged more flexibly to suit GP work schedules.

Familial adenomatous polyposis (FAP) is an autosomal dominant disorder caused by mutation of the APC gene. It is characterised by the appearance of hundreds to thousands of colorectal adenomas in adolescence and the subsequent development of colorectal cancer. Various extracolonic malignancies are associated with FAP, including desmoids and neoplasms of the stomach, duodenum, pancreas, liver, and brain. We present a family affected by FAP with an exon 14 APC mutation displaying two rare extracolonic lesions, a hepatoblastoma and a myoepithelial carcinoma. The hepatoblastoma was found in a male patient aged 2 years. The second lesion, a myoepithelial carcinoma of the right cheek, was found in a female patient aged 14 years. Inactivation of the normal APC allele was demonstrated in this lesion by loss of heterozygosity analysis, thus implicating APC in the initiation or progression of this neoplasm. This is the first reported case of this lesion in a family affected by FAP.
