Uterine artery embolization for symptomatic fibroids with imaging follow up

The aim of this study was to determine the effectiveness of uterine artery embolization (UAE) as a primary treatment method in treatment of symptomatic fibroids, whether there are any preembolization MRI characteristics of fibroid predictive of reduction in volume and assess reduction in uterine and dominant fibroid volumes using ultrasound (US) and MRI. Study was carried out in total of 32 patients aged 25–49 years (mean 40.9 years). Uterine and dominant fibroid volume were determined using US and MRI before UAE, MRI and US at 3 months and US alone at 6 and 12 months post‐UAE, supplemented by clinical evaluation at interval of 3, 6 and 12 months. Procedure was carried out through unilateral femoral puncture using poly vinyl alcohol (PVA) particles 355–500 μm in size. All 32 patients had successful procedures. Overall, 25 patients responded, giving a clinical success rate of 78.12%. Mean reduction in volume of uterus and fibroid was 33 and 59.7% and 48.9 and 75.5% on US at 3 and 12 months respectively, and 33.3 and 58.6% on MRI at 3 months. Volume reduction on US and MRI at 3 months was highly correlative. There was no statistical difference in size reduction in volume of fibroids, which were hypointense or hyperintense on T2‐weighted image (T2WI) on pre‐UAE MRI. Uterine artery embolization leads to good technical success and fibroid volume reduction. Ultrasound alone may be used for follow up of patients post‐UAE. Preprocedure signal characteristics on T2WI are not predictors of volume reduction after UAE.     

Colour duplex Doppler ultrasonography evaluation of non‐vasculogenic male erectile dysfunction: An Indian perspective

We present the study of colour duplex Doppler ultrasonography on Indian patients with non‐vasculogenic erectile dysfunction. Patients with a history suggestive of psychogenic impotence along with a normal clinical response to intracavernosal papaverine were presumed to have non‐vasculogenic erectile dysfunction. In our patients, the incidence of psychogenic impotence was much higher and the mean age of patients presenting with erectile dysfunction was lower as compared to patients from developed countries reported in research. The Doppler flowmetry showed much higher mean peak systolic velocities (PSVs) with a negative correlation between age and PSV. End diastolic velocity, resistive index and acceleration time values conformed to the literature.     

Establishing good practices in continuing care: a descriptive study of community nursing services for people with HIV infection

This paper presents findings from a 2-year study of community nursing services for people affected by HIV infection in six health authorities in England The research, commissioned by the Department of Health, England, aimed to identify the main bridges and barriers to effective home nursing care, focusing on discharge co-ordination, district nursing and multi-agency collaboration Using a triangulated, case study approach, the main methods of data collection included non-participant observation, case note analysis, semi-structured staff interviews, a postal questionnaire of district nurses and a series of focus groups with service users Study sites included three cities and surrounding districts in the north west, north and south east of England Findings suggest there is considerable room for improvement in discharge planning and that good practice is not the preserve of specialist units District nurses are shown to be willing providers of the majority of home nursing care to this client group, but there is a need for more focused training, greater use of care co-ordinators and more emotional and managerial support     

The theory/practice 'gap': taking issue with the issue

Theory/practice issues have a long-standing history in nurse education, and are a chronic source of controversy to which there is no easy or perfect solution We have argued that it is the tension between theory and practice and research which can be usefully exploited in teaching and research Students need to be introduced to the debates surrounding the genesis and generation of nursing knowledge They need to gain an appreciation of what counts as nursing knowledge at different points in time and the politics which drive the legitimation of nursing theory and practice Such an approach has much to offer in helping students deal with reality shock and make sense of their experience as they confront the ambiguities, uncertainties and contradictions that characterize the stock-in-trade of professional life     

Students'' expectations of postregistration degree programmes

The needs of postregistration students pursuing degree-linked clinical courses have received little attention and there are few insights concerning their aspirations when they enrol on such courses. Thus the aim of this study was to explore postregistration students' perceptions of the specific needs of their patient/client group and to examine how they envisaged the course on which they had just enrolled might help them to meet these needs in addition to their own requirements for professional and personal development. Data were collected by group interview from 62 students enrolling on eight different postregistration courses, all employed in an acute hospital trust. The results were analysed inductively. They indicated that students had internalized the state of the healthcare market and were keenly aware of the need to fulfil the expectations of employers and the public, while fulfilling their own needs for education and pursuing their own professional and career trajectories. They appeared ambitious and yet appeared to demonstrate empathy for patients and their families and felt a tremendous desire to provide care of a high quality through the optimal development of technical expertise. Students' emphasis on the importance of keeping abreast of technological developments should not be lightly dismissed considering its prominent position within the acute areas where they were employed, especially as it did not replace their desire to promote the caring aspects of their work.     

新缩瞳剂包公藤甲素人工合成研究

Osteosarcoma: use of MR imaging and MR spectroscopy in clinical decision making

Magnetic resonance (MR) imaging was performed on 14 patients with histologically proved osteosarcoma (mean age, 14.4 years). There was excellent correlation of intramedullary tumor extent as determined with MR imaging and pathologic examination (r = 99%). This was facilitated by the presence of a chemical shift artifact at the tumor-marrow interface on the T1-weighted images. The correlation between CT and pathologic findings was not as good (r = 84%). In a single patient, however, a 10-cm length of sclerotic bone was incorrectly interpreted as being tumor. If this case is excluded, the correlation between CT and pathologic findings improves significantly (r = 96%). T2-weighted images were optimal in demonstrating soft-tissue bulk and breach of the epiphysis or cortex. Vascular involvement was also readily defined. The T2 value of the tumor soft-tissue component decreased in patients who were deemed to have responded well to therapy. Two patients with very high T2 values after chemotherapy developed wide-spread metastatic disease and died. Phosphorus-31 MR spectroscopy of five patients with osteosarcoma showed elevated levels of phosphomonoesters (PMEs), inorganic phosphate (Pi), and phosphodiesters (PDEs). PME and PDE peak areas decreased in three patients after chemotherapy, while Pi peak areas increased.
