Managing asthma in accident and emergency departments: an assessment in non teaching hospitals

Background: The management and follow-up of asthma patients presenting at Accident and Emergency (A&E) departments have mostly been studied in children's hospitals or specialised teaching hospitals. Aims: To study the adequacy of assessment, treatment and follow-up of patients presenting at A&E departments in non-teaching hospitals. Methods: A twenty-five per cent sample of presentations to A&E departments in all public hospitals in the Illawarra for one year was selected for a case note audit. Information on demographics, assessment, management and referral was extracted from the A&E case notes and medical records of cases with documentation of a final diagnosis of asthma. Chi square and Fischer's Exact tests were used for comparisons among hospitals. Results: Of 359 presentations with a final diagnosis of asthma, 88% were self referred and only 5% were first presentations. Objective measures of airways obstruction was not documented in 34% of admissions and 48% of nonadmissions. There was no documented follow-up in 28% of cases. The assessment and management of asthma in A&E was significantly poorer in smaller hospitals. Conclusion: Evidence of high use of A&E as a primary care facility by asthma patients was found in the study. There is a need to implement protocols to optimise assessment and treatment of asthma in smaller hospitals. (Aust NZ J Med 1993; 23: 672–677.).     

肥胖类型与脑卒中亚型的相关性研究

目的探讨肥胖类型与脑卒中亚型的相关性。方法将573例急性脑卒中患者分为脑出血组126例,脑梗死组447例,脑梗死组再分为脑血栓形成组(215例)和腔隙性脑梗死组(232例),另外选择277例无脑卒中者为对照组。测量腰围、臀围和体重,计算体重指数和腰臀比(WHR),分析肥胖参数与脑卒中各亚组的关系。结果脑卒中各亚组与对照组肥胖发生率差异无显著性意义(P>0.05);各组WHR明显大于对照组(P<0.05)。WHR增大明显增加脑卒中各亚组的危险性(P<0.05);女性腹围增大患腔隙性脑梗死危险性升高(P<0.05);男性体重增加患脑出血的危险性升高(P<0.01)。结论腹型肥胖是脑出血、脑血栓形成和腔隙性脑梗死的危险因素之一。     

床上体操训练对偏瘫患者的效果观察

目的：观察偏瘫患者早期床上训练的效果。方法：对５８例脑血管意外致偏瘫患者随机分成２组：观察组３０例，护理中指导早期床上体操训练；对照组２８例，按常规护理。以上、下肢肌力和日常生活活动能力（ＡＤＬ）为评价指标，于训练开始时、训练４周、训练８周各评价１次。结果：观察组训练４周、８周时患侧上肢肌力以及ＡＤＬ水平明显增加，与对照组比较有显著差异（Ｐ＜００１）。患侧下肢肌力训练４周及８周时均增加，与对照组比较，４周时无明显差异（Ｐ＞００５），８周时有显著性差异（Ｐ＜００１）。结论：对早期偏瘫患者实施床上功能训练，不仅可以提高患者的生命质量，而且可以减少、甚至解除患者及家属的经济和精神负担。     

平时罕见,特殊情况下发生的几种伤病

一些损伤和疾病平时罕见，特殊情况下可以发生，造成严重危害。特殊情况主要包括严重事故、灾害、战争、恐怖主义活动以及特殊环境与特殊作业的危害等。本阐述了现代战争中发生的贫铀武器伤害、燃料空气炸弹伤害、微波武器伤害和战时精神疾病；可能源于恐怖主义活动的炭疽、天花；严重事故性伤害中的核事故、化学事故和煤矿事故伤害；严重灾害中的地震、海难(海战)落海伤害。中介绍了这些伤病的发生情况、伤害特点与医学救治。     

脑卒中患者吞咽障碍及康复效果影像学研究

目的探讨电视X线透视吞咽功能检查（videofluoroscopic swallowing study,VFSS）在脑卒中患者吞咽功能评估中的应用价值,观察脑卒中后吞咽障碍发生情况,康复前后患者吞咽功能变化.方法脑卒中患者70例及健康成人80名分别作为研究组与对照组均进行VFSS,比较两组误吸等VFSS异常征象的发生情况.对发现误吸患者进行吞咽功能康复训练4周,训练后复查VFSS,比较训练前后吞咽异常的发生情况变化.结果对照组渗透或误吸、口腔滞留、咽腔滞留的发生率为5.0%,13.4%,25.3%.主要为轻度渗透及口咽腔滞留.研究组渗透或误吸、口腔滞留、咽腔滞留发生率为45.0%,46.5%,48.9%,主要为重度渗透或误吸,中重度口咽腔滞留.其中隐匿性误吸为10次（占总误吸的24.4%）.误吸患者康复治疗后渗透或误吸发生率较康复治疗前减少（P＜0.05）.结论脑卒中后吞咽障碍在康复期仍较为常见,可表现为多种影像学异常.VFSS可确切诊断吞咽异常,进行针对性康复训练,使患者吞咽功能提高.     

The effects of alcohol and benzodiazepines on the severity of ski accidents.

Urine samples from 402 victims of ski accidents were analyzed for the presence of benzodiazepines (BZD) and alcohol. Eighty-one (20%) samples were positive for alcohol; BZD were detected in 34 (8.5%) cases. Ten of the samples (2.5%) were found to be positive for both alcohol and BZD. Subjects who were positive for either alcohol or BZD or both were older than the other persons examined. The prevalence of alcohol was significantly higher among male accident victims. BZD intake could be demonstrated to have a significant influence on the severity of injuries. Besides an increased awareness of the need for skier education regarding drug use, heightened attention of medical caregivers is warranted to inform their patients about potential accident hazards in sport activities when BZD are prescribed.     

缺血性脑血管病患者的血脂水平

目的分析缺血性脑血管病（ICVD）患者的血脂水平，为今后预防保健及康复干预决策的制定提供依据。方法在佛山市第一人民医院病案数据库中检索1991-2004年诊断为ICVD的病例共2886例，其中2000-2004年ICVD患者共1430例为一亚组，以我院同时期保健科随机选取的400名健康体检人群为对照组，记录血脂情况，进行对照分析。结果血TC、TG和LDL—C水平ICVD患者组明显高于健康体检人群，差异有统计学意义。男女两性血脂水平均随年龄增加而逐渐增高，50岁以上女性血脂水平明显高于同龄组男性。血脂代谢异常患病率随着年代的推移呈逐步上升趋势，总胆固醇从1991—1994年的24．5％到2001-2004年的38．1％（男性）和22．3％到38．5％（女性），且明显高于国内2000-2001年普查人群高脂血症的患病率。结论佛山地区血脂异常是ICVD的重要原因之一。     

Effect of environment on extremely severe road traffic crashes：retrospective epidemic analysis during 2000-2001

Objective: To make an epidemiological analysis of the effect of environment on extremely severe road traffic crashes (RTCs). Methods: Epidemiologic data of extremely severe RTCs associated with environmental factors, including weather, topography, road conditions and other traffic conditions in Mainland China during 2000-2001, were collected and analyzed. Results: ( 1 ) During 2000-2001, there were 3 365 extremely severe RTCs with 13 666 deaths, 12 204 injuries and a direct economical loss of 136 million RMB. ( 2 ) Most extremely severe RTCs occurred in fine weather days and in the daytime. The high occurrence sites were plain areas, horizontal and straight roads, Grade B and C roads, ordinary road segment, and asphalt, smooth and mixed roads. (3) Compared with other RTCs, extremely severe RTCs were more likely to happen under following conditions: on cloudy, snowing, misty and blustering days; in hill and mountainous areas; on crooked and sloping roads; on freeway, Grade A, B, and C roads; mixed roads; ordinary, bridge, narrow and transitional roads; sand and dirt-roads; without traffic control measures; night without lighting. (4) Extremely severe RTCs of mountainous area or crooked and sloping roads were most severe in terms of deaths and injures per crash. Conclusions: Extremely severe RTCs are closely related with environmental factors. Rational road programming, enhancing road establishment and improving road conditions are probably effective measures to reduce the road traffic injuries.
