871例干部体检的X线胸片分析

871例干部体检的X线胸片分析结果表明:正常者254例,正常率仅29.2％,且随年龄的增长而降低。主要病变有慢性支气管炎、主动脉增宽与迂曲,而且还发现了3例肺癌,说明胸部平片检查在体检中仍具有重要的意义。     

山东省德州地区已婚育龄妇女弓形虫筛查状况分析

目的:了解已婚育龄妇女弓形虫感染情况以及探讨弓形虫的感染途径、感染与不良生育的关系。方法:于1998年12月～2000年12月采用ELISE方法对1042例育龄妇女进行了TOX-IgM的筛查及有关情况调查。结果:本市已婚育龄妇女TOX-IgM平均感染率为12.18％,正常妊娠组及不良生育组显著高于未孕组(P<0.05);郊区妇女高于市区妇女(P<0.05);有动物接触史及有生食习惯的妇女显著高于无接触史及生食习惯者(P<0.05)。结论:TOX感染是引起不良生育的重要原因之一。建议育龄妇女孕前孕期加强TOX筛查工作,以及早诊治;加强健康教育,改变不良生活习惯;加强水源、粪便等卫生管理。     

Predictors of Repeat Emergency Department Visits by Elders

Objective: To determine which characteristics of older patients who use a hospital ED are associated with repeat visits during the 90 days following the index visit.
Methods: The study was conducted in the ED of a 400-bed university-affiliated acute care community hospital in Montreal. Patients aged ≥75 years who visited the ED between 08:00 and and 16:00 on a convenience sample of days over an 8-week period (July and August 1994) were assessed using a questionnaire, physical and cognitive status instruments, and a functional problem checklist. The hospital's administrative database was used to identify repeat visits during the 90 days following the ED visit. The representativeness of the sample was assessed by analyses of ED visits made by 4,466 persons aged ≥65 years during a 12-month period (September 1993 to August 1994) using the hospital's administrative database.
Results: 256 patients aged ≥75 years visited the ED during the study period and 167 were assessed. Of these, 54 (32%) were admitted to the hospital. Among the 113 patients released from the ED, 27 (24%) made repeat visits during the next 90 days. In univariate analyses, repeat visits were significantly associated with the number of functional problems, cognitive impairment, and previous ED visits. In multiple logistic regression, male gender, living alone, and number of functional problems were independent predictors of repeat visits. In the administrative data analyses, nighttime arrival to the ED for the index visit was significantly associated with repeat visits.
Conclusions: Self-reported risk factors can help to identify a group of elders likely to make repeated ED visits; the development of a screening instrument incorporating questions on these problems and implementation of appropriate interventions might improve these patients' quality of life and reduce the demand for further ED care in this age group.     

紧急纤维支气管镜在老年高危患者中的应用

目的　研究紧急纤维支气管镜 (纤支镜 )在老年高危患者中的应用。方法　老年急危重症患者 77例 ,其中急性生理和慢性健康评估 (APACHEⅡ )计分 >14分者 65例。所有患者共行 10 2例次紧急纤支镜操作 ,其中肺泡灌洗、气道分泌物吸引 76例次 ;纤支镜引导下经鼻气管插管 19例次 ;异物吸出 6例次。结果　 10 2例次紧急纤支镜操作抢救总有效率为 80 .3 % ,无危及生命的并发症发生。结论　紧急纤维支气管镜是抢救急危重症患者呼吸道病变紧急处理的有力武器 ,高龄严重心、肺功能障碍不是纤支镜操作的禁忌证     

Perceptions of severely and multiply disabled persons

Data from studies of rankings of acceptability and severity of various disabilities were converted to a common metric of percentile equivalent ranks. A total of 1331 data points from 53 studies yielded the following overall percentile equivalent ranks for 24 disabilities: diabetes (most acceptable), ulcer, arthritis, asthma, heart condition, speech problems, crippled, orthopedic disability, physical disability, amputation, emotional disturbance, appearance disability, deafness, learning disability, stroke, cancer, paraplegia, blindness, epilepsy, tuberculosis, cerebral palsy, mental retardation, mental illness, and multiple disabilities (least acceptable). Rankings of the severity of seven disabilities yielded a somewhat different order that correlated 0.55 with the total data. Rankings of a mild disability were, on average, 40 percentile points higher than rankings for the same disability labeled severe or profound.     

提高老年骨折的临床治疗水平

本期《中华创伤骨科杂志》是以“老年骨折”为主要内容的重点刊，涉及老年股骨转子间骨折，肱骨近端骨折，桡骨远端骨折．股骨远端、髌骨、胫骨干、踝关节等部位骨折的内固定手术治疗。骨质疏松是老年人发生骨折的高危因素之一，也是骨折后导致处理棘手的原因所在。除了骨质疏松，由于老年人通常有各种并存症的存在，愈发增加了老年骨折的处理难度。如何提高骨折的治疗质量及预防再骨折的发生成为目前处理老年骨折的工作重心。     

DSP-4, a noradrenergic neurotoxin, produces more severe biochemical and functional deficits in aged than young rats

The present study examines the effects of noradrenergic lesions (either DSP-4 i.p. or 6-hydroxydopamine (6-OHDA) into the dorsal noradrenergic bundle on biochemical (noradrenaline (NA), dopamine (DA), serotonin (5-HT) and choline acetyltransferase (ChAT) activity) and cortical EEG (quantitative EEG (qEEG) and high-voltage spindle (HVS) activity in young and aged rats. Near complete 6-OHDA NA lesions, but not partial DSP-4 NA lesions, increased HVS activity in young rats. DSP-4 and 6-OHDA lesions produced no significant changes in the 5-HT or DA levels or in the ChAT activity in young rats. In some of the aged rats, DSP-4 produced similar biochemical and HVS effects, as it induced in young rats. In the remainder of the aged rats, NA levels were greatly and 5-HT levels slightly decreased. DA levels and ChAT activity were unaltered in either set of aged rats. HVS activity was increased only in that group of aged rats with the greatly lowered NA content. These results suggest that: (1) some of the aged rats are more sensitive to DSP-4 treatment than young adult rats; and (2) NA depletions have to be complete to produce an increase in HVS activity in young and aged rats.

Osteoporosis and Back Pain among the Elderly

Questionnaire responses from 120 men and 337 women over the age of 50 years were studied to determine the prevalence of back pain among the elderly. In order to gain a rough indication of the back pain among elderly women which might be due to osteoporosis, the prevalence was compared in the two sexes. The prevalence of back pain without radiation to the legs and concomitant morbidity was found to be similar among men and women up to the 70–79-year age-group. After this age the prevalence was higher in women. Those with exceptional loss of body height or kyphosis had a high prevalence of back pain, while those who had sustained previous hip or radius fractures did not. There was increasing prevalence of back pain among women with increasing number of previous fractures. The study gives little indication of serious morbidity of osteoporosis in the form of back pain before very old age.     

高原地区健康老年人重返平原后外周血T细胞亚群变化的观察

用单克隆抗体测定了移居高原的老年人重返平原后的T细胞亚群的变化结果:①移居西宁(2260m)组、天峻(3000m)组在西宁所测的OKT_3、OKT_4、OKT_8及OKT_4/OKT_8值与在苏州所测的当地老年人无差异。②移居西宁组急返平原后OKT_3、OKT_8水平明显低于返回平原后居住一年以上者(以下简称返回组)(P<0.01～0.001)但OKT_4/OKT_8无差异。③返回组与世居苏州老年人相比,前者OKT_3、OKT_4、OKT_8及OKT_4。OKT_8增高,其中OKT_3、OKT_4增高明显(P<0.01～0.02),作者认为长期移居高原返回平原后T细胞亚群也可能存在一“脱适应”阶段,即机体重新调整重新平衡的一种形式,这一阶段可能需一年以上。
