Professional Education in Co-occurring Disorders: Some Considerations towards Practice Development

The aims of this paper are to provide a brief overview of the types of education and training as well as a framework for co-occurring disorders courses at foundation and advanced levels. Mental health nurses encounter substance abuse problems as part of their workload and should be prepared adequately to work with individuals with the co-existence of mental health and substance abuse. However, co-occurring disorders are not often picked up by substance abuse or mental health services, indicating a need for improvement in ongoing professional development. The targeted audience for education and training in core competencies should be staff working in community mental health teams, inpatient services, assertive outreach teams, early intervention teams, crisis resolution teams, primary care, mental health services for older people, independent mental health projects, accommodation services, day care services, statutory drug and alcohol services, independent drug and alcohol service providers, and those working in hostel accommodations, housing, prison health care probation, and others in the criminal justice system. The theoretical and skills-based training will need to adopt a two-tiered approach as individuals working within mental health services will by definition need a higher emphasis on training around substance misuse and vice versa for individuals working in substance misuse services. One of the agenda items for interagency training is to challenge negative attitudes and prejudices around both mental health problems and substance misuse.     

Linear and Whorled Nevoid Hypermelanosis: Report of a Case Associated with Cerebral Palsy

Abstract: A child had cerebral palsy and linear and whorled nevoid hypermelanosis on the right side of his body. He had spasticity and wasting in both lower limbs, with electroencephalographic changes and brain abnormalities on computerized tomographic scan. Chromosomal study of peripheral blood leukocytes found a normal male karyotype. The pathogenesis of this condition is still unclear.     

155 vascular injuries: a retrospective study in Kuwait, 1992-2000.

OBJECTIVES: To audit the management of vascular trauma in Kuwait, 1992-2000. DESIGN: Retrospective open study. SETTING: Vascular surgery unit, teaching hospital, Kuwait. SUBJECTS: 155 patients with vascular injuries, most of which (n = 118) involved the extremities. 21 had neck injuries, 10 abdominal, and 6 chest. INTERVENTION: Revascularisation usually using the long saphenous vein in addition to direct repair or end-to-end anastomosis. MAIN OUTCOME: Morbidity (amputation) and mortality. RESULTS: Four lower limb grafts failed, two of which (2/69, 3%) required amputation. Overall, four patients died (3%), one of pulmonary embolism and 3 of severe injuries to major abdominal vessels. 3/10 patients with abdominal vascular trauma died. Mean (SD) follow up period was 4.4 (2) years. CONCLUSIONS: Civilian violence has increased in Kuwait. Vascular trauma to abdominal vessels is associated with high mortality. Autogenous saphenous vein forms an excellent conduit for revascularisation.     

Schistosomiasis in a cystic teratoma of the ovary

The authors report the case of an ovarian teratoma infected by the eggs of the trematode Schistosoma haematobium. In consideration of the rare observation, bearing a paradigmatic value, they briefly discuss the particular tropism that the parasite demonstrated towards some tumoral structures and they also outline the immunological mechanisms activated by the Schistosoma.     

Protection against cyclophosphamide-induced alopecia by sulfhydryl-containing agents in the newborn rat animal model

Background Alopecia is a common side-effect of cancer chemotherapy. Although this complication has been known for many decades, little progress has been made in its prevention or treatment. Previously, we made the following observations: ( a ) treatment of 8-day-old rats with 1-0-n-arabinofuranosylcytosine (ara-C), doxorubicin, and cyclophosphamide (CYC) produced either total body alopecia (ara-C and CYC) or alopecia confined to the head and proximal part of the neck (doxorubicin); ( b ) Imuvert, a biological response modifier, and interleukin-1 protected against alopecia-induced by ara-C; and (c) neither Imuvert or interleukin-1 protected against CYC-induced alopecia. Objective Experiments were designed to test for agents to protect against CYC-induced alopecia. Methods Agents were tested in the 8-day-old rats as a model for chemotherapy-induced alopecia. Results Mesna and S-2-(3-aminopropylamino)-ethylphospnorothioic acid (WR-2721) did not offer any protection against chemotherapy-induced alopecia. N-Acetylcysterine offered very good protection against alopecia induced by CYC but not that produced by ara-C in the newborn rate animal model. Conclusion N-Acetylcysteine may prove to be important in the prevention of CYC-induced alopecia, but this needs to be tested in the clinical setting.     

Nursing and substance misuse: responding to the challenge

The widespread use and misuse of alcohol, drug and other psychoactive substances are major health and social concerns that affect the lives of many The social and health sequelae of psychoactive drugs and alcohol are preventable and manageable with minimal interventions Nurses and other health workers can effectively respond to substance misuse problems and their existing generic skills can be easily adapted in working with substance misusers This paper considers some of the issues such as the extent of the problem, attitudinal considerations, response to substance misusers and a brief outline of the role of the nurse The urgent need for education and training in substance misuse and addictive behaviour for nurse practitioners is also addressed     

Rapid detection and quantitation of hepatitis B virus DNA by real-time PCR using a new fluorescent (FRET) detection system.

BACKGROUND: The diagnosis of hepatitis B virus (HBV) has until recently been based on traditional serologic methods targeting viral antigens and antibodies to viral proteins. The development of molecular methods allowing for the quantitation of HBV DNA is proving clinically valuable for monitoring therapy and detecting early treatment failures. OBJECTIVES: Here we report a new real-time (LightCycler) quantitative PCR for the detection of HBV DNA based on sequence specific hybridisation probes (designed in-house), targeting the HBV surface antigen. STUDY DESIGN: The assay was evaluated using a 10-fold dilution series of standard HBV DNA [Eurohep standard reference 1, genotype A, HBsAg subtype adw with a unitage of 10(6) WHO. i.u./ml] and 89 clinical serum samples. The performance was measured against a quantified standard HBV DNA working reagent (NIBSC code 98/780) and the sensitivity compared with our conventional thermal-block PCR. RESULTS AND CONCLUSION: Real-time PCR detected HBV DNA in 45% (40/89) and thermal-block PCR in 16% (14/75) of clinical samples. Results for 26 samples were below the detection limit of the thermal-block PCR but could be quantified by real-time (LightCycler) PCR. The LightCycler assay was at least 5 logs more sensitive than thermal-block PCR and could detect HBV in a linear range between 5 and 10(7) i.u. per reaction. The broad generic nature of the PCR primers coupled with the enhanced sensitivity and specificity of the fluorescent hybridisation probes makes this assay potentially valuable for both routine diagnostic and epidemiological work.     

Arterial supply of the temporo-medial region of the brain significance for preoperative vascular occlusion testing

The mesiobasal limbic system is of particular significance in the surgical treatment of temporo-medial tumors and epilepsy. It consists of the uncus, amygdaloid body, hippocampus, dentate gyrus, subiculum, fasciolar gyrus and the parahippocampal gyrus. Knowledge of the vascular microanatomy is a key to the surgical treatment of pathologies in the region. The anterior choroidal artery was selectively injected in fresh brain specimens 50 specimens with a gelatinous ink mixture to demonstrate vascular territories in stereotactic brain slices, and 50 with a Biodur resin to obtain casts for microanatomical evaluation. The cast technique was also applied to 35 specimens injected into the posterior cerebral artery. The rostral third of the temporomedial region is mainly supplied by branches of the anterior choroidal artery. The occipital two thirds are supplied by hippocampal branches, the posteromedial choroidal artery and the inferior temporal branches of the posterior cerebral artery. Important vessel variations with significant implications for the preoperative Wada-test are presented     

Alterations of mononuclear inflammatory cells, CD4/CD8+ T cells, interleukin 1beta, and tumour necrosis factor alpha in the bronchoalveolar lavage fluid, peripheral blood, and skin of patients with systemic sclerosis

BACKGROUND: Systemic sclerosis (SSc) is a multisystem disease with underlying immune mechanisms. AIMS: To investigate the clinicopathological characteristics of the lesions; immunological alterations in the bronchoalveolar lavage fluid (BALF), peripheral blood, and skin; and correlations between the clinicopathological characteristics and immunological alterations in SSc. MATERIALS/METHODS: Skin biopsies, BALF, and peripheral blood samples were obtained from 19 patients (18 women, one man) with SSc and six age and sex matched healthy controls (HCs). Mononuclear inflammatory cells (MICs), CD4/CD8 cells, tumour necrosis factor alpha (TNFalpha), and interleukin 1beta (IL1-1beta) concentrations were examined in all samples using histological methods, enzyme linked immunosorbent assay, and immunoperoxidase staining. RESULTS: The mean (SD) age of the patients with SSc was 34.8 (2.6) years. Proteinuria, positive rheumatoid factor, and C reactive protein were seen in 15.8%, 26.3%, and 26.3% of patients, respectively. Compared with HCs, there were significantly higher: total MICs (macrophages, lymphocytes), neutrophils, and eosinophils in BALF, blood, and skin (all p<0.05); cytokine concentrations in BALF (TNFalpha, p<0.001; IL-1, p<0.01) and peripheral blood (p<0.01 and p<0.05); and CD8/CD4+ T cells in peripheral blood (p<0.05). Compared with HCs, lesional skin had significantly higher histiocyte cell counts (p<0.05), lower lymphocyte counts (p<0.05), and higher CD4/CD8 ratios (p<0.001). There were significant correlations between cytokine concentrations and CD8+ T cells and forced vital capacity (p<0.001 and p<0.01, respectively). CONCLUSIONS: MICs, CD4/CD8+ cells, and cytokines are altered in SSc. These alterations correlated with the underlying disease process and therefore may have pathogenic, modulatory, and potential prognostic roles in SSc.     

Apoptosis in the ovary: molecular mechanisms

Cell death was first described in rabbit ovaries (Graaffian follicles), the phenomenon being called 'chromatolysis' rather than apoptosis. In humans, the ovarian endowment of primordial follicles is established during fetal life. Apoptotic cell death depletes this endowment by at least two-thirds before birth, executed with the help of several players and pathways conserved from worms to humans. To date, apoptosis has been reported to be involved in oogenesis, folliculogenesis, oocyte loss/selection and atresia. Several pro-survival and pro-apoptotic molecules are involved in ovarian apoptosis with the delicate balance between them being the determinant for the final destiny of the follicular cells. This review critically analyses the current knowledge about the biological roles of these molecules and their relevance to the dynamics of follicle development. It also presents the existing literature and assesses the gaps in our knowledge.
