The role of laparoscopy in the diagnosis of ectopic pregnancy: A plea for conservative management

This report evaluates the role of laparoscopy in patients admitted with the diagnosis of “Rule Out Ectopic”. There were 186 patients admitted to the Brookdale Hospital Medical Center in the 6-year period 1974–1979 inclusive with a diagnosis of “Rule Out Ectopic” or “Possible Unruptured Ectopic”. These patients were all laparoscoped. There were 157 satisfactory and 27 unsatisfactory laparoscopies. There were 71 ectopic pregnancies: 42 ruptured, 25 unruptured. Thirty-six cysts were diagnosed. The value of early laparoscopy is clearly established. Particular emphasis is placed on the diagnosis of the unruptured ectopic so that appropriate conservative management of the tube can be instituted in order to preserve potential reproductive capacity.     

基于Repast平台的SARS传播仿真建模研究

通过引入基于主体的建模思路和方法,根据易于描述的微观个体行为,利用Repast仿真建模平台对SARS的传播过程进行模拟,从而研究SARS传播宏观层面的规律,并根据謇验结果提出了疫情防控的策略和措施.本文初步构造了SARS传播的主体模型,定义了主体的状态转换方式以及主体之间的行为规则,并实现了一个可用于模拟SARS传播过程的简单的仿真建模框架,通过可动态扩展的规则设定、模型参数调节,为研究SARS传播提供了方便的模拟环境.     

Impact of the Final Rule on the Rate of Clinical Cardiac Arrest Research in the United States

Background: The federal government placed a moratorium on human emergency resuscitation research in 1993 due to concerns related to informed consent. In 1996, the Food and Drug Administration introduced the Final Rule in order to allow clinical resuscitation research to proceed in special cases without prospective informed consent. It is unclear, however, how this change has impacted the performance of this research. Objectives: To measure the potential impact of the Final Rule by determining the number of clinical cardiac arrest studies performed in the United States (US) before and after 1993, and to compare it with the number of studies performed in the European Union (EU) during the same periods. Methods: A MEDLINE search was performed for cardiac arrest studies that were prospective, interventional, randomized, and performed in the US or EU from 1983 through 2003. Results: Of the 3,115 cardiac arrest publications identified, 66 (2%) met inclusion criteria. Of the 40 studies conducted in the US, 24 (60%) were published prior to or during 1993, whereas of the 27 studies conducted in the EU, six (22%) were published prior to or during 1993 (odds ratio = 0.5; 95% confidence interval = 0.3 to 0.8). Conclusions: There has been a significant decrease in the number of published clinical cardiac arrest trials in the US since 1993. In contrast, there has been a significant increase in the number of published EU trials since 1993. The current informed consent requirements may have reduced the number of clinical cardiac arrest studies performed in the US.     

Current severe psoriasis and the rule of tens

This review addresses the problems of defining severity of psoriasis. Concepts of severity depend on the timescale perspective from which judgement is made. Measurement needs to include assessment of signs, impact on the patient's life and the history of the disease. The concept of severity in relationship to quality of life measurement scores has been defined, so it is now possible to postulate a standard, easily remembered concept to help define 'severe psoriasis' in the clinic. The proposed Rule of Tens for current severe psoriasis from the clinician's viewpoint is: 'Current Severe Psoriasis = Body Surface Area involved > 10% or Psoriasis Area and Severity Index score > 10 or Dermatology Life Quality Index score > 10'.     

Appraising current methods for preclinical calculation of burn size – A pre-hospital perspective

Background

Calculation of the percentage of total body surface area burnt is a vital tool in the assessment and management of patients sustaining burns. Guiding both treatment and management protocols. Currently there is debate as to which method of estimation is the most appropriate for pre-hospital use.

多分辨分析提取心率变异性中的睡眠结构信息

本文从工程分析的角度探索通过分析心率变异性推知健康人夜间睡眠结构的可行性、针对心率变化在睡眠过程中的特点,对心动间期信号作基于小波变换的多分辨率分析,深入考察了不同睡眠时相中的RRV(R-R interval variability)多分辨率信号,尤其在睡眠时相转换时的变化特点.建立了关于健康人睡眠规律和睡眠RR规律的规则库.综合分析RRV在多分辨率下的信息,用模糊逻辑推理系统对某时间段不同睡眠时相的隶属度进行推理.经对26例健康人睡眠RRV分析,与脑电人工分析结果比较,睡眠基本结构的平均符合率达到85%,醒觉和睡眠状态的平均符合率达到93%,证明用本方法进行睡眠结构分析是可行的.
