Prostatitis versus pelvic pain syndrome: Immunologic studies

The pathogenesis of chronic pelvic pain syndrome continues to be an enigma. The observation of inflammatory cells in urine, ejaculate, prostate fluid, and prostate tissue combined with changed local expressions of cytokines, immunoglobulins, complement, and other inflammatory markers led to the hypothesis of an involvement of the immune system in this clinical entity. This review presents a survey of the immunology-related data available for chronic pelvic pain syndrome and attempts to explain them in the context of causes and consequences.     

Molecular characterization of the Caenorhabditis elegans ALP/Enigma gene alp-1.

Members of the ALP/Enigma family of PDZ-LIM proteins play a role in cytoskeletal anchorage and mutations in at least one member of this family are associated with human cardiomyopathy. Here, we describe the analysis of the Caenorhabditis elegans alp-1 gene. alp-1 is predicted to encode the entire nematode ALP/Enigma protein family, consisting of one ALP-related protein with a single LIM domain and three Enigma-like proteins containing four LIM domains. We demonstrate that the ALP-1 proteins are expressed in muscle cells, where they localize to actin anchorage and muscle attachment sites. We show that the PDZ domain of the ALP-1 proteins is sufficient to target the protein to the dense bodies, which are important actin anchorage sites in C. elegans body wall muscle. We demonstrate that the C. elegans ALP/Enigma proteins are also localized to cell-cell junctions and to both epithelial and muscle cell nuclei. These findings suggest new roles for the ALP/Enigma protein family that may lead to the understanding of their involvement in cardiomyopathy.     

The incidence of error in young children's Wh-questions.

Many current generativist theorists suggest that young children possess the grammatical principles of inversion required for question formation but make errors because they find it difficult to learn language-specific rules about how inversion applies. The present study analyzed longitudinal spontaneous sampled data from twelve 2-3-year-old English speaking children and the intensive diary data of 1 child (age 2;7 [years;months] to 2;11) in order to test some of these theories. The results indicated significantly different rates of error use across different auxiliaries. In particular, error rates differed across 2 forms of the same auxiliary subtype (e.g., auxiliary is vs. are), and auxiliary DO and modal auxiliaries attracted significantly higher rates of errors of inversion than other auxiliaries. The authors concluded that current generativist theories might have problems explaining the patterning of errors seen in children's questions, which might be more consistent with a constructivist account of development. However, constructivists need to devise more precise predictions in order to fully explain the acquisition of questions.     

Relapse rate and outcome of ANCA-associated small vessel vasculitis after transplantation.

BACKGROUND: Anti-neutrophil cytoplasm antibody-associated systemic vasculitis (AASV) is a rare disease and frequently leads to end-stage renal disease (ESRD). Potentially fatal disease activity can develop after the onset of ESRD or in transplanted patients despite the immunosuppressive effects of uraemia and rejection prophylaxis, respectively, leading to concern that such patients may have greater morbidity and mortality. METHODS: To assess the outcome of patients with AASV following kidney transplantation, a retrospective analysis was performed of nine patients with AASV at our unit who received renal transplants between 1987 and 2000. The renal survival of the patients was compared with a control population who received kidney transplants over the same period for causes other than AASV and diabetes mellitus. RESULTS: Nine patients with the diagnosis of AASV (five patients with Wegener's granulomatosis and four with microscopic polyangiitis) received eight cadaveric grafts and one live-related graft after a mean of 44 months from the start of dialysis. These patients had a mean age of 49.2 years at time of transplantation and they were followed up for a mean of 62 months post-transplantation. Two patients with Wegener's granulomatosis suffered a vasculitic relapse affecting the upper respiratory tract at 40 and 50 months post-transplantation, corresponding to a relapse rate of 0.04 per patient per year. The renal transplant function of vasculitis patients compared with 18 non-diabetic control patients who were transplanted at the same time was better in the vasculitis patients at some time points (P=0.054 at 6 months). CONCLUSIONS: There is a substantial relapse rate in the AASV population, especially affecting the upper respiratory tract and with increasing duration of follow-up. Nonetheless, renal transplantation is a good option for the treatment of vasculitis patients and their outcome compares favourably with that of other non-diabetic patients following transplantation.     

The implications of Project 2000 and the formation of links with higher education for the professional and academic needs of nurse teachers in the United Kingdom

A national study was conducted between 1991 and 1994 to explore and describe the changing role of the nurse teacher following the introduction of Project 2000 pre-registration nursing courses. Multiple methods were used to collect data from a wide variety of respondents (nurse teachers, midwife teachers, clinical nurses, health service managers and higher education lecturers). This paper presents the findings relating to the impact of Project 2000 and the move into higher education on the continuing educational needs of nurse teachers. Views on college strategies for staff development, the changing nature of teachers'academic and professional development needs and the problems of the conflicting demands experienced are reported. The research highlights the need for clinical credibility to be clearly defined in relation to nurse teachers and for educational institutions to place more emphasis on teachers'clinical development if the rhetoric of policy is to become a reality.
