A case study identifying nursing staffs'' perception of the delivery method of nursing care in practice on a particular ward

The research describes how nursing staff on a general surgical ward in a district general hospital perceived the delivery method of nursing care in practice. The study design was based on ethnographic methods and data were collected by diary keeping and semi-structured interviews. An organizational method based on the principles of primary nursing had been implemented on the ward for 2 years prior to the study commencing. As well as talking in general terms about primary nursing, the nursing staff talked at some length about specific issues related to their practice.     

呋苄青霉素药代动力学及组织分布的研究

呋苄青霉素是由我国开发成功的一个酰脲类青霉素。本项研究采用微生物法,以狗和正常人为受试对象,以氧哌嗪青霉素和羧苄青霉素为对照进行药代动力学研究,结果表明,3个药的药—时曲线符合二室开放式模型,呋苄青霉素较其它对照药具较高的即刻血浓度和较低的肾清除率。用微生物法和放射自显影法测定的呋苄青霉素在小鼠体内组织分布汪明,呋苄青霉素广泛分布于体内各组织,尤其在肺、肝、肠中的浓度明显高于羧苄青霉素。

本文较详细地介绍了应用激光技术即用CO_2及Nd:YAG激光手术刀治疗各种类型痔的临床观察。我院自1988年应用CO_2及Nd,YAG(以下简称激光手术刀)的技术治疗各种痔1376例均取得满意的治疗效果,治愈率达100％,并对有关问题进行探讨。     

用ROC曲线评价肿瘤标志物LDH在急性白血病早期诊断中的临床价值

目的 探讨肿瘤标志物乳酸脱氢酶（LDH）在急性白血病早期诊断中的临床价值。方法 应用受试者工作特性曲线（ROC曲线）及其曲线下面积（AUC）抛物线估算法（以金标准计算准确度和敏感度），对51例急性白血病的早期患者及部分经治疗后缓解的患者、61例非急性白血病患者、61例健康体检者进行了LDH的检测及分析。结果 AUC为0．954，其可信区间为0．935－0．973，其下限0．935远离0．5，经治疗缓解的白血病患者LDH检验结果与治疗前数据经t检验证实＜0．0001。结论 LDH对急性白血病的早期诊断以及治疗效果与预后的评估均有着重要及较好的临床价值。     

Detection of subclinical ascorbate deficiency in early Parkinson''s disease

From mid-October 1989 to mid-July 1990 all newly admitted residents to Bury Local Authority Residential Homes were comprehensively medically screened. In a series of 100 residents eight had early Parkinson's disease (six of them hitherto undiagnosed). Seven showed evidence of Vitamin C deficiency. Of the seven showing evidence of deficiency, four suffered from early Parkinson's disease. Of the 93 without evidence of Vitamin C deficiency only four had Parkinson's disease. This indicates a significantly higher prevalence of Parkinson's disease in the group with Vitamin C deficiency (P less than 0.001 using Fisher's exact).     

Tachycardia''s toll: tachycardia induced cardiomyopathy — a case study

Cardiac arrhythmias are a well known cause of mortality for patients with heart disease. However, sinus tachycardia is a more unusual arrhythmia which can lead to serious heart damage or death. Even young patients with structurally normal hearts may become gravely ill.

This case study outlines the condition of sinus tachycardia, and associated changes in heart function, altered cellular structure of the myocardium and compensatory mechanisms in the body. Treatment modalities, including electro-physiological studies and drug therapies to moderate the tachycardia and myocardial oxygen demand of the heart, are discussed. Fourteen year old ‘Ben’ was previously a well, active and outgoing youth who suddenly became critically ill. He endured weeks of hospitalisation, numerous serious complications including Torsade de pointes arrhythmia, Cheyne-Stokes respirations, nausea and dizziness during this acute phase. Despite challenges, Ben's severely compromised heart muscle recovered at a remarkable rate.
