小肠系膜扭转的诊治体会

目的探讨小肠系膜扭转的临床特点、诊断和治疗方法。方法对2002年8月～2010年2月间15例小肠系膜扭转的患者进行回顾性分析。结果术前明确诊断6例,诊断为粘连性肠梗阻5例,腹痛待查5例,急性腹膜炎4例,均采用手术探查,死亡4例。结论肠系膜扭转的诊断主要依靠临床表现和CT,此病一旦诊断应立即手术。     

社会工作实践中价值中立是可能的吗——析社会工作理论与实践的关系

对社会工作理论与实践关系的定位,直接关系到对社会工作学科本质的整体判断,更间接影响到社会工作的服务理念和服务方法。以实证论为代表的主流观点主张要用价值中立的客观态度去理解外在世界活动。而实际工作中,很难实现全然价值中立。价值相关性的价值介入观承认选题上的价值相关,但仍把研究过程看作是不含价值成分的事实与事实之间的关系;强烈价值介入观则强调在社会研究中,研究者必然会自觉或不自觉地加入自己的价值判断。社会工作理论与实践的关系,并非是一个事实与事实之间的关系,它在实践中涉入了强烈的社会工作者的价值判断,而社会工作者在实务社会工作中的实践,其实是一种道德上的实践。

Efficient algorithms for shared backup allocation in networks with partial information

We study efficient algorithms for establishing reliable connections with bandwidth guarantees in communication networks. In the normal mode of operation, each connection uses a primary path to deliver packets from the source to the destination. To ensure continuous operation in the event of an edge failure, each connection uses a set of backup bridges, each bridge protecting a portion of the primary path. To meet the bandwidth requirement of the connection, a certain amount of bandwidth must be allocated the edges of the primary path, as well as on the backup edges. In this paper, we focus on minimizing the amount of required backup allocation by sharing backup bandwidth among different connections. We consider efficient sharing schemes that require only partial information about the current state of the network. Specifically, the only information available for each edge is the total amount of primary allocation and the cost of allocating backup bandwidth on this edge. We consider the problem of finding a minimum cost backup allocation together with a set of bridges for a given primary path. We prove that this problem is NP-hard and present an approximation algorithm whose performance is within of the optimum, where n is the number of edges in the primary path. We also consider the problem of finding both a primary path and backup allocation of minimal total cost. A preliminary version of this paper appears in the Proceedings of 13th Annual European Symposium on Algorithms - ESA 2005, Mallorca, Spain. J.

Women's Experience of Co-Occurring Substance Abuse and Mental Health Conditions

ABSTRACT

This study explored the relationship between gender and co-occurring substance abuse and mental health conditions among a sample of 754 consumers of behavioral health services in the southwest U.S. Logistic regression was used to determine factors that would predict women's unique experience of dual diagnosis. Women were almost seven times more likely than men in this sample to have a diagnosis of posttraumatic stress disorder in conjunction with substance abuse. Women were also significantly more likely to experience anxiety and mood disorders and to have been married. Implications of these findings for social work practice are suggested.     

Confronting Myths and Stereotypes About Borderline Personality Disorder

SUMMARY

The clinician treating a patient with borderline personality disorder (BPD) is often faced with complicated challenges, from making and communicating an accurate diagnosis, to implementing an appropriate, informed plan for treatment. Myths and stereotypes about BPD, and the individuals who may carry the diagnosis, likely complicate effective recognition and treatment of the disorder. BPD has been a controversial diagnosis among clinicians since its inception, and it is poorly understood among the general public. Pressures to avoid an explicit exploration of the diagnosis stemming from myths and stereotypes about the disorder can come from a number of sources, including other clinicians, family members and patients themselves. The results of minimizing or ignoring the contribution of borderline pathology may be detrimental. Clinical decisions based on outmoded thinking about diagnosis, prognosis, treatment efficacy, and availability of resources may deny patients optimal care. Integrating current findings into consideration of a BPD diagnosis and design of appropriate treatment, free of misconceptions about the condition, may help limit the untoward effects associated with failure to appreciate elements of borderline personality.     

College Women Eating Disorder Diagnostic Profile and DSM-5

Abstract

A consistent diagnostic profile describing college women with eating disorders has been well established in the college health and mental health literature. This diagnostic framework traditionally has been associated with the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision¹ Eating Disorders Not Otherwise Specified category. In this article, the authors discuss implications of the recently revised Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition² eating disorder diagnostic categories for the existing college women eating disorder profile.
