Effects of patient deaths by suicide on clinicians working in mental health: A survey

In the UK, at least a quarter of suicides occurs in patients whilst under the care of mental health services. This study investigated the effects of such deaths on non-medical mental health clinicians. An online survey was conducted within a single NHS mental health Trust to elicit both quantitative and qualitative responses from staff across a range of professions. The survey focused on personal and professional impacts and available support. Participants reported significant negative emotional and professional effects that were long-lasting for some. These included mental health difficulties, loss of confidence regarding clinical responsibilities, and actual or contemplated career change. However, there was also some evidence of positive effects and professional growth. Support from colleagues and line managers is clearly important following deaths of patients by suicide. Clinicians' experiences of the support they had received in the workplace were polarized, suggesting that there is no single nor ideal approach that will meet everyone's needs. Participants made recommendations for the types of support that may be helpful. Most commonly, clinicians desired opportunities for focused reflection and support and help with the formal processes following the death. Sensitivity around how clinicians are notified about the death was highlighted as being particularly important. Conclusions are drawn as to how training institutions and employers can help staff to be better prepared for the potential occurrence of patient suicides and the formal processes that follow, with a view to mitigating risks of more serious harm to staff and hence indirectly to patients, and potential loss of highly trained clinicians to the workforce.     

Health screening for people with learning disabilities by a community learning disability nursing service in Northern Ireland

Over the last 30 years there has been a considerable increase in the life expectancy of people with learning disabilities. This has resulted in changing patterns of morbidity and mortality and an increasing recognition of the health needs of people with learning disabilities. Major strides forward have been made in the reduction of preventable illnesses among the general population. However, among people with learning disabilities such illnesses have received only limited health promotion attention until recently. In the last decade major gaps have been identified in the ability of current primary health services to respond to the needs of people with learning disabilities. The need to respond effectively to this situation has been identified as a priority by the current United Kingdom Government. Following an overview of the literature in relation to the changing health profile of people with learning disabilities and the need for health screening, consideration is given to some of the key difficulties which may be encountered when attempting to utilize current primary health services. The analysis of data derived from the health screening of 373 people with learning disabilities by a community nursing service in Down and Lisburn Health and Social Services Trust reveals the need for further action in relation to cardiovascular status, sensory deficits, mobility and aspects of sexual health.     

Aetiological factors for oral manifestations of HIV

OBJECTIVES: Describe the oral diseases in HIV-infected individuals in London, UK and identify social and medical factors related to the presence of specific oral diseases.
DESIGN: Cross-sectional analytic study.
SETTING: Dental clinics.
SUBJECTS: Consecutive sample of 456 patients with HIV infection.
METHODS: Social and medical history and clinical examinations. Univariate and logistic regression analysis.
OUTCOMES: Presence of HIV-associated oral disease.
RESULTS: 80% of patients with AIDS and 50% of patients with HIV had a specific oral disease. The most common diseases were hairy leukoplakia (30%), erythematous candidiasis (24%), pseudomembranous candidiasis (14%), angular chielitis (6%), necrotising periodontal disease (8%) and non-recurrent ulceration (6%).
CONCLUSIONS: The presence of erythematous candidiasis was not related to advanced HIV disease. Pseudomembranous candidiasis, hairy leukoplakia and mucosal ulceration were significantly associated with advanced HIV disease. Smoking was also identified as a strong aetiological factor in oral diseases. Longitudinal studies are required to further explore the prognostic significance of oral diseases in HIV infection.     

Detection of homozygous deletions of the cyclin-dependent kinase 4 inhibitor (p16) gene in acute lymphoblastic leukemia and association with adverse prognostic features

A recently described putative tumor suppressor gene, the cyclin- dependent kinase 4 inhibitor (p16), has been shown to be altered by deletions and/or point mutations in various human cancers. To assess the incidence and clinico-biologic correlations of p16 homozygous deletion in hemopoietic tumors, we studied a panel of 244 DNA samples representative of distinct acute (99 cases) and chronic (57 cases) leukemia subtypes, myelodysplastic (22 cases) and myeloproliferative (15 cases) syndromes, and lymphomas (51 cases). A 361-bp probe complementary to the p16 exon 2 gene sequences was generated by polymerase chain reaction and used in Southern blot hybridization against these tumor DNAs. Homozygous deletions of p16 (p16-/-) were detected in 10 of 58 (17%) cases of acute lymphoblastic leukemia (ALL) of either B or T lineage and in no other tumors. Single-strand conformation polymorphism analysis of p16 exons 1 and 2 was also performed in 40 of the 58 ALL cases and in 16 lymphomas. In no cases were point mutations detected. The comparison of clinical features at presentation in p16-/- and in p16 germline ALL cases showed a greater leukemic cell mass (P = .001) and higher white blood cell counts (P = .01) in the former group. Two ALL cases in which diagnostic and relapse DNA samples were available showed p16-/- in both specimens. We conclude that homozygous p16 gene deletions characterize a subset of ALL with features of aggressive disease.     

Hemophilia A: carrier detection and prenatal diagnosis by DNA analysis

In this study, we used DNA polymorphisms for carrier detection and prenatal diagnosis of hemophilia A in a large group of Italian families. The restriction fragment length polymorphisms (RFLPs) investigated were the intragenic polymorphic Bc/I site within the factor VIII gene; the extragenic multiallelic Taq I system at the St14 locus; and the extragenic Bg/II site at the DX13 locus. The factor VIII probe was informative in 30%, St14 in 82%, and DX13 in 60% of obligate carriers. The combination of factor VIII-Bc/I and St14-Taq I showed that 91% of obligate carriers were heterozygotes for one or both; with all three probes, only 4% of obligate carriers were noninformative. In families clearly segregating for hemophilia A, RFLP analysis allowed us to define the carrier status for the hemophilia A gene in all 27 women tested. RFLP analysis allowed us to exclude the carrier status in 39 of 45 female relatives of sporadic patients. The combination of RFLP analysis and biological assay of factor VIII allowed us to identify a de novo mutation in the maternal grandfather in 7 of 12 of the families with sporadic cases, for which members of three generations were available for study. Nine of 10 couples requesting prenatal diagnosis provided informative RFLP DNA pattern. Carrier status was excluded in two women, two fetuses were shown to be female, and prenatal diagnosis was carried out in five pregnancies by DNA analysis. Prenatal testing was successful in three instances and failed in two because a sufficient amount of chorionic villous DNA was not obtained for the analysis.
