Tobacco smoking: a major risk factor for loss of teeth in three 70-year-old cohorts

Oral health was examined in a random sample of 1377 people in three 70-year-old cohorts studied within 5-yr intervals. During the studied period 1971-1983 the prevalence of toothlessness decreased from 52 to 34%. Toothlessness in men was more common in smokers, 48%, and ex-smokers, 32%, than in non-smokers, 20%. Eichner's index was used as a measurement of dental invalidity. This index showed a worse dental state among smokers and ex-smokers compared to non-smokers. Multivariate analyses indicated that tobacco smoking was a major independent risk factor for tooth loss in elderly men.     

TEN YEARS' EXPERIENCE IN LOW VISION PRACTICE

The Low Vision Clinic at the Palmerston North Hospital has now been oerating for 70 years. Over the course of these ten years a number of factors have emerged which can be as readily applied to general ophthalmological practice as to low vision practice. The philosophy of low vision care is one of which all ophthalmologists should be aware and includes factors to be taken into account when dealing with children, people in the workplace, and everyday factors involved in daily living activities, all of which are equally relevant in routine ophthalmological practice. This paper endeavours to share some thoughts on these factors and also discusses means by which the visually handicapped can be helped in areas where specialist low vision services are not readily available.     

老年人根管治疗疗效的相关因素

目的:研究老年人根管治疗疗效及其影响因素.方法:对56例65岁以上老年人,根管治疗后2年以上的126颗牙齿进行检查,按治疗后年限分3组:2～3年组,4～5年组,6年以上组.应用根尖周指数(Periodicalindex)评定X线片和综合临床检查,对其治疗进行评价.结果:老年人根管治疗成功率为72.2%;三组间根管治疗成功率差异无显著性.恰填根管治疗的成功率(82.2%)比欠填和超填的成功率(47.2%)要高;恰填病例中,冠方修复体质量好的患牙比质量差的患牙根尖周炎发病率低(25.7%和58.4%);去除欠填和超填病例后,桩冠修复患牙的根管治疗成功率为58.8%,而未做桩冠修复的患牙成功率为87.5%.结论:根充质量、冠方修复体质量、桩冠修复是影响老年人根管治疗疗效的主要因素.     

老年人急性阑尾炎的腹腔镜手术治疗

目的 探讨老年人急性阑尾炎的临床特点，更好地把握腹腔镜阑尾切除（LA）术的方法和特点。方法 回顾分析50例老年人急性阑尾炎LA的临床资料。结果 LA均获成功，患者全部治愈，无严重的并发症发生，肠功能恢复时间及住院时间均缩短。结论 老年人反应迟钝，阑尾炎进展快，易发生坏疽及穿孔，合并症多，手术风险较高，LA是安全、可行的，除个别腹膜后阑尾炎外，其余均可施行LA。     

老年男性心肌缺血患者心率变异分析（附67例报告）

采用正常搏动ＲＲ间期的标准差（ＳＤ）及心率变异指数（ＨＲＶ ｉｎｄｅｘ）作为指标，分析６７例老年男性心肌缺血患者的心率变异，并与正常老年男性组及正常青壮年男性组进行了对比，发现前组的ＲＲ间期ＳＤ、ＨＲＶｉｎｄｅｘ均明显低于后两组，其结果有显著性差异（Ｐ均〈０．０１）。提示心肌缺血可破坏交感与迷走神经的均衡性，造成心率变异降低。     

Removal of famotidine by haemodialysis in elderly anuric patients

Summary The effect of haemodialysis on the pharmacokinetics of oral famotidine has been studied in five elderly anuric patients. Famotidine 20 mg was administered in a cross-over design to patients on and not on haemodialysis.The elimination rate constant of haemodialysis (k) was 4.6-fold larger than the systemic elimination rate constant (k_e). Although the mean maximum serum concentration of famotidine during haemodialysis (141.5 ng·ml^–1) was not significantly lower than that without haemodialysis (195.6 ng·ml^–1), the AUC up to 5 h during haemodialysis was significantly decreased to 58.1% of the value without it.The data suggest that famotidine is dialysable by haemodialysis.     

Preconditions for and consequences of self-determination: the psychiatric patient's point of view

In the context of an interview study concerned with self-determination in psychiatric patients, this paper describes the preconditions for and consequences of self-determination from the point of view of psychiatric patients themselves. The data were collected in semi-structured interviews with long-term psychiatric patients ( n =72) and analysed using the method of content analysis. Responses on the preconditions for self-determination were grouped into three categories: firstly, there were those who said that reference to self-determination in the case of psychiatric patients is nonsense; secondly, there were those who said that self-determination requires no preconditions; and thirdly, there were those who said that there are certain preconditions, such as the ability to think and make decisions, activity, obedience, and illness. Both positive and negative consequences were identified in situations where self-determination is maintained, but only negative consequences in situations where self-determination is lost. On the basis of these tentative results, self-determination seemed to be relevant in psychiatric nursing. We are continuing to develop and test an instrument for the evaluation of the opportunity for self-determination in clinical practice.     

心包内处理肺血管及心房部分切除治疗中心型肺癌

１９８７年５月至１９９３年１２月对１６例较晚期肺癌采用心包内处理肺血管及心房部分切除的方法作了全肺切除术，肿瘤均为中心型。ＣＴ扫描显示隆突下或主肺动脉窗淋巴结肿大者占５０％，术中见肺动脉，肺静脉均受累者８例，肺静脉受累者６例，２例作左心室部分切除，１５例恢复良好，１例术中大出血致心脏停搏，复苏后并发脑水肿昏迷死亡。我们认为，心包内处理肺血管全肺切除提高了手术切除率，且手术过程较安全可靠，作者对这种
