The Tasmanian children's project: the needs of children with a parent/carer with a mental illness.

This paper presents some of the key findings and recommendations of the report The Tasmanian Children's Project (TCP): The Needs of Children with a Parent/Carer with a Mental Illness, October, 1999. The TCP, a collaborative venture between the University of Tasmania's School of Nursing and the Mental Health Services - South, Tasmania (Department of Health and Human Services), is the first study in Tasmania to formally examine the needs of children where the parent/carer has a mental illness. The study is a modified replication and extension of the 1993/94 Victorian Children's Project. Extension aspects of the TCP included interviews with children (in addition to parents and service providers), the inclusion of data on both maternal and paternal mental illness and a broad definition of mental illness (beyond psychotic illness and major affective disorder). The report highlights the need to provide a range of programs that encourage the development of personal competency among children, parents, and other family members and those that emphasize interagency collaboration. Implications of this research for mental health nursing education and practice are also addressed.

The North Staffordshire Suicide Study: a case-control study of suicide in one health district.

BACKGROUND: The aim of the study was to identify sociodemographic and clinical risk factors for death from suicide and undetermined injury in residents of one health district. METHOD: Data were collected on all cases of suicide (ICD-9 E950-959) and undetermined injury (ICD-9 E980-989) for residents in North Staffordshire Health District between 1991 and 1995. Controls identified from the Coroner's inquest register, who died from other causes, were matched for age and sex. RESULTS: Two hundred and twelve pairs of cases and matched controls were identified. Multivariate analysis (conditional logistic regression) showed that the risk of death due to suicide and undetermined death was associated with: recent separation, relationship difficulties, experience of financial difficulties, history of past criminal charges or contact with the police, a past history of deliberate self-harm, being on psychotropic medication at the time of death and a diagnosis of bipolar affective disorder. For sociodemographic variables, a univariate analysis found associations between the cases and being separated, living alone, having a past history of criminal charges and unemployment. Cases were more likely to have a psychiatric disorder, past history of deliberate self-harm and a past history of psychiatric contact for themselves or a family member. Controls were more likely to have a current medical disorder. Cases were more likely than controls to be on any form of medication at the time of death and to have received a prescription for psychotropic or non-psychotropic medication in the week and month before death. Cases were more likely than controls to have had contact with medical services in the week and month before death, with the general practitioner in the week before death and with psychiatric services at any time in the year before death. Strong associations were found between suicide and undetermined injury and life events such as recent separation and bereavement, and financial and relationship difficulties. CONCLUSIONS: The study provides an analytical investigation utilizing a dead control group, data gathered from several sources and adequate numbers of cases. It confirms many of the risk factors identified in other studies and highlights the high proportion of suicides who have been in recent contact with the criminal justice system or have been prescribed medication shortly before death.

Arthroscopy in the elderly.

Arthroscopy of the knee is an accepted and widely practised diagnostic and therapeutic procedure. The role of arthroscopy in the elderly is examined in this study. The benefit of debridement in the control of symptoms in the degenerative knee even in this elderly population is demonstrated. Arthroscopy produced an improvement in 62.3% of patients and in those whose knees were being assessed for osteotomy or arthroplasty 55% have avoided further surgery.

Characteristics of the core protein of the aggregating proteoglycan from the Swarm rat chondrosarcoma.

A ternary complex of hyaluronic acid-binding region and link protein bound to hyaluronic acid was isolated from limit clostripain digests of proteoglycan aggregates isolated from the Swarm rat chondrosarcoma. Under these conditions, the hyaluronic acid-binding region has a molecular weight of approximately equal to 65,000 (HA-BR65). N-terminal amino acids in the complex were selectively 14C-carbamylated. The resulting derivatized HA-BR65 was isolated, and tryptic peptide maps were prepared and developed on two-dimensional TLC sheets. A single, labeled peptide was obtained which gave a Mr by approximately equal to 8,000 by SDS-PAGE. Chymotrypsin digestion of the ternary complex reduced the molecular weight of HA-BR65 to a polypeptide of approximately equal to 55,000 (HA-BR55) which still retains the same N-terminal tryptic peptide. Partial digestion of proteoglycan aggregates with clostripain generated a series of larger intermediates with the hyaluronic acid-binding region. Direct SDS-PAGE analysis revealed one major intermediate with approximately equal to 109,000 (HA-BR109) as well as HA-BR65. After chondroitinase digestion, two additional prominent intermediates were observed on a SDS-PAGE gel at Mr approximately equal to 120,000 (HA-BR120) and approximately equal to 140,000 (HA-BR140). All the intermediates were recognized by a monoclonal antibody specific for the hyaluronic acid-binding region, and all of them contained the same N-terminal tryptic peptide. The results indicate that the N terminus of the core protein is at the hyaluronic acid-binding end of the proteoglycan and that the chondroitin sulfate chains are first present on the core protein in a region between 109,000 and 120,000 molecular weight away from the N terminus.

The aggregation of human platelets by ascitic fluid: a possible mechanism for disseminated intravascular coagulation complicating LeVeen shunts.

To identifiy causative factors responsible for the disseminated intravascular coagulation complicating peritoneovenous (LeVeen) shunts, the ascitic fluid from 12 patients with alcoholic liver disease or peritoneal malignancy was examined for its effects on human platelets. In all patients, concentrated ascitic fluid caused irreversible platelet aggregation. Properties of the aggregating factor suggested that it is collagen, and subsequently, the presence of collagen in ascitic fluid was confirmed. This finding, together with the known effects of collagen on platelets and contact clotting factors, would be sufficient to explain the development of disseminated intravascular coagulation following this procedure. Aspirin by inhibiting collagen-induced aggregation may have a therapeutic role in the management of this problem.
