Analysis of the inflammatory response in endovascular treatment of aortic aneurysms.

OBJECTIVE: The objective of this study is to evaluate the inflammatory response caused by endovascular stents in the treatment of aortic aneurysms. METHODS: Twenty-five patients underwent endovascular stent treatment from March through December 2005. The evolution of mediators (sedimentation velocity, C reactive protein, interleukin-6, interleukin-8, tumor necrosis factor-alpha, intercellular adhesion molecule-1, l-selectin), inflammatory cells (leukocytes, lymphocytes, platelets), serum creatinine and body temperature within preoperative period and in the following postoperative periods--1, 6, 24 and 48 h, 7 days, 1-3 months, was analyzed. In order to achieve statistic significance, Friedman test and Wilcoxon test were used, with index of significance of 5% (p<0.05). RESULTS: Peak values of sedimentation velocity, C reactive protein and interleukin-6 were observed at 7 days (p<0.0001), 48 h (p<0.0001) and 24h (p<0.0001), respectively. Tumor necrosis factor-alpha and interleukin-8 did not show statistically significant variability during the entire follow-up. In terms of intercellular adhesion molecule-1 and l-selectin, their expressive values were found in late phase of follow-up, although without statistical significance. Elevation of leukocytes count occurred in premature phase of follow-up (p<0.0001), while lymphocyte and platelet count occurred in a late phase of follow-up (p<0.0001). Serum levels of creatinine did not show significant variability during follow-up. The period between 24 and 48 h corresponded to major frequency for fever (p<0.0001). CONCLUSION: Individual mediators analysis and inflammatory cells demonstrated variability of their values during postoperative follow-up. This could help in the analysis of the inflammatory response evolution caused by endovascular stent treatment for aortic aneurysms in premature and late phases after implantation of the vascular prosthesis.     

Skin cancers and precancerous lesions in Parkinson's disease patients.

Our objective was to evaluate the frequency of neoplastic and preneoplastic skin lesions in Parkinson's disease (PD) patients when compared with an aged-matched population. We performed a cross-sectional survey in PD patients and in an age-matched control group. Patients and controls were examined by a movement disorder specialist and a dermatologist. 150 PD patients and 146 controls were included. Thirty-five PD patients (23.3%) presented skin lesions that could be classified as neoplastic or preneoplastic vs. 20 subjects in the control group (13.7%) (OR 95%, CI 1.92 [1.05, 3.51]). However, this difference lost statistical significance when adjusted for gender (recruitment of controls was matched just for age with an over representation of males in the PD group). Twenty-nine PD patients (19%) presented actinic keratosis and basal cell carcinoma was diagnosed in 4 patients (3%). Although nonconclusive, our results are in agreement with previous studies suggesting an increased risk of skin cancer in PD patients. The frequency of actinic keratosis in PD patients and the associated risk to develop melanoma recommends its screening in future epidemiological studies.     

乳腺病变X线立体定位钢丝置入移位的分析

目的分析乳腺立体定位下钢丝置入移位的表现、原因、处理方法，提高术前定位的准确性。方法行立体定位置入钢丝患者79例，96个病变，发生钢丝移位13例。结果立体定位中发生钢丝移位5例，原因分别来自于患者和操作医师；立体定位完成后钢丝移位5例，原因是局麻注射药物过多，导致乳腺Z轴的深度与计算机提示的实际深度不符合、放置定位针的方法不正确、拔出钢丝外套针套时疏忽钢丝是否已锚定病变。处理方法：可按照钢丝提示位置向病变方向移位2cm以内进行手术，重新放置第2根钢丝，将双J型钢丝收入针套并取出体外，重新定位。手术中钢丝脱出2例，因术后过分提拉钢丝所致，放射科医师放置钢丝后应向外科医师准确描述深度、方向，并从距离钢丝头端距离皮肤最近处取切口手术。术后标本未见钙化1例，与钙化位于手术电刀破坏的腺体内有关，可扩大范围切除并短期复查，证实钙化是否完整切除。结论正确认识乳腺X线立体定位下钢丝移位的表现，熟练掌握其处理方法，可提高对不可触及的乳腺病变的定位准确性，正确引导外科手术。     

先天性肩胛骨高位症1例

患者男,37岁。因雷管爆炸致全身多发皮肤金属伤入院,胸部X线示:右侧肩胛骨明显抬高,肩胛骨上端平颈6椎体上缘水平,肩胛骨与颈椎间可见骨性条形影,左侧肩胛骨未见明显异常。双侧胸部可见多发点状、不规则形高密度影。诊断:右侧肩胛骨高位伴“肩椎骨”形成;双侧胸部多发异物影,结合病史考虑为多发皮肤内金属影。讨论:先天性肩胛骨高位症又称肩胛骨下降不全,本病是肩胛骨在胚胎发育过程中,由于受到某种因素的影响,如宫内压增高,肩胛带肌肉发育不良,肩胛骨与脊柱之间有异常连接而发生下降障碍所至。单侧发病者多表现为双侧颈肩部不对称,患侧颈…     

医院用血液制品HCV污染情况的调查

To market! To market! A new dawn for community care?

The public sector in Britain has been subjected to over a decade of major reform aimed at breaking up public service monopolies, at containing costs while at the same time opening services up to greater consumer choice. Health and social services have not been exempt from this revolution in the organization and management of public sector services. The long-standing policy of care in the community is being subjected to market principles and the introduction of a ‘contract culture’ very similar to the NHS reforms introduced in 1991. This paper reviews the origins of these developments in the doctrines of ‘new public management’, a movement which has proved attractive to policy-makers in many countries. Local authority social services departments have been identified as the lead agency for the development of a mixed economy of care following a review of community care policy by the government's health adviser, Sir Roy Griffiths, and a subsequent white paper. This paper examines the limited empirical evidence available on how managers and providers are meeting the challenge bestowed upon them, and concludes that most authorities are moving ahead cautiously if at all. Only a handful of authorities studied have embraced the reforms with any degree of enthusiasm. The paper concludes with an assessment of the reforms from two perspectives: a pessimistic one and an optimistic one. There are many worrying features of the reforms, not least among these being a lack of clarity over their intended purpose. Tensions and contradictions are plentiful, which places in jeopardy the certainty of the reforms in becoming user led rather than provider driven. A more optimistic scenario is that the changes are leading to a loosening up of services and practices which have often suffered from sclerotic tendencies, paternalism and sometimes complacency. If the reform process is skilfully handled and not rushed and if the ends are clearly established and communicated then users and carers could prove to be the principal beneficiaries.     

Needs assessment for persons with severe mental illness: What services are needed for successful community living?

The development and implementation of effective community support systems are goals of many public mental health authorities who are attempting to shift the focus and dollars for mental health services from inpatient to community care. This article presents the results of a survey which asked 90 community mental health agency case managers to assess the community support and residential needs of over 1400 of their clients. Medication monitoring and therapy were rated high priority needs. Psychosocial treatment, day and vocational activities also ranked high. Survey responses regarding residential services indicated a need for more supported and supervised options.The study reported was a collaborative effort by county and agency staff.     

Cognitive behaviour therapy approach to disputing automatic thoughts: a two-stage model

Research shows that clients with automatic thoughts (dysfunctional thinking) often do not think of alternative explanations in relation to negative events. Furthermore, these automatic thoughts are characterized by a broad global, self-evaluative and ambiguous nature that could make disputing (or changing the ways they think) the most difficult part of the therapeutic process. This paper proposes a two-stage practise-based disputing model, guided by research, that aims to 'bring' an automatic thought to a specific, objective, quantifiable and concrete level at which not only is the particular aspect(s) of the automatic thought that causes emotional disturbances finely focused, but the disputing is also likely to be effective and manageable. Furthermore, it will also generate alternative explanations that are helpful in reducing emotional disturbances and in facilitating problem solving approach. In this paper, the authors use a case example to discuss the rationale that underpins the conceptualization of the model and to illustrate the process in which the strategies of the model are effectively used.
