Geriatric care on a ward without nurses

The Multiphasic Environmental Assessment Procedure (MEAP; Moos and Lemke, 1984) was used to assess three long-stay settings within a geriatric hospital, one of which is a non-nursing unit committed to the philosophy of residents viewing the setting as their own home. Findings suggest positive outcomes for residents on the nonnursing unit, and support the view that types of care fostering independence and personal responsibility of elderly residents in their setting may be associated with increased mental functioning and activity. The lack of trained nursing staff had no detrimental effect on any measure of resident life, and some specific caring practices on the unit may be interpreted as having a positive outcome for residents.

老年人颅脑外伤后缺血性脑卒中发作特点及治疗

目的探讨老年人颅脑外伤后缺血性脑卒中发作特点及个性化治疗方案。方法针对7例颅脑外伤后急性期出现缺血性脑血管病症状的老年患者，通过脑血管造影检查分析其发病原因并根据不同的脑血管特点决定治疗方案。结果大多数患者（6／7）受伤前已存在不同程度的颅内外血管狭窄、血管壁溃疡以及附壁血栓形成等改变，提示脑缺血发作主要与这些病变为基础的脑血流下降、血栓脱落等因素密切相关。而外伤后脑灌注降低、脑血管痉挛是脑缺血发作的诱发因素。结论老年人外伤后的缺血性脑卒中发作主要与原有的脑血管基础疾病有关，预防和治疗老年人外伤后缺血性脑卒中发作，应基于这些病变特征并选择个体化治疗方案。     

老年人慢性腰腿痛病因分析及临床治疗

目的探讨老年慢性腰腿痛的常见病因及其治疗。方法选择1997年1月至2000年12月间162例老年慢性腰腿痛患者，椎间盘突出92例（其中合并腰椎管狭窄者63例），单纯腰椎管狭窄10例，腰椎峡部裂或滑脱者37例，骨质疏松者23例。结果47例患者经保守治疗后出院，但其中18例症状复发。115例患者行手术治疗，其中椎板间扩大开窗或半椎板切除髓核摘除75例，全椎板切除髓核摘除9例，单纯峡部植骨术8例，脊柱内固定者23例。97例手术患者获得随访，平均18个月，症状消失或明显缓解者65例，残留部分症状者29例，无改善者3例。结论脊柱退行性变是导致老年人慢性腰腿痛的主要原因，以腰椎间盘突出和椎管狭窄为主，治疗上先予保守治疗，效果差时可积极手术治疗。     

老年患者尿路感染菌群分布及其耐药性分析

目的 :了解老年患者尿路感染致病菌的菌群分布及其对抗生素的耐药情况 ,为临床合理使用抗生素提供依据。方法 :收集湖北省 15所三级甲等医院 2 0 0 2年尿路感染老年患者清洁中段尿细菌培养分离的 5 34株致病菌 ,对其进行耐药性监测。药敏采用K B法 ,用WHONET 5软件进行数据分析。结果 :共收集致病菌 5 34株 ,其中革兰阴性菌 4 0 9株 (76 .6 % ) ,革兰阳性菌 12 5株(2 3.4 % )。革兰阴性菌中大肠埃希菌检出率最高 (2 6 4株 ,4 9.4 % ) ,其次为克雷白杆菌 (44株 ,8.2 % )。 16 .7%的大肠埃希菌和 2 2 .7%的克雷白杆菌产超广谱 β 内酰胺酶。亚胺培南、阿米卡星、头孢他啶对革兰阴性菌的抗菌活性最强 ,而革兰阴性菌对环丙沙星、庆大霉素、哌拉西林的耐药率均在 5 0 %以上。革兰阳性菌以肠球菌最多见 (6 4株 ,12 % ) ,其次为葡萄球菌属 (43株 ,8.1% )。革兰阳性菌对SMZco、红霉素等的耐药率均在 4 0 %以上 ,但对万古霉素均敏感。结论 :老年患者尿路感染以革兰阴性菌为优势菌株 ,且耐药性日益严重 ,对亚胺培南、阿米卡星、头孢他啶最为敏感。革兰阳性菌宜以万古霉素为首选。     

Risk groups for clinical complications of norovirus infections: an outbreak investigation

Norovirus infections have been described as self-limiting diseases of short duration. An investigation of a norovirus outbreak in a university hospital provided evidence for severe clinical features in patients with several underlying diseases. Clinical outcomes of norovirus infection were defined. Risk-factor analysis targeting underlying diseases and medication was performed using multivariate analyses. In five outbreak wards, 84 patients and 60 nurses were infected (an overall attack rate of 32% in patients, and 76% in nurses). The causative agent was the new variant Grimsby virus. Severe clinical features, including acute renal failure, arrhythmia and signs of acute graft organ rejection in renal transplant patients, were observed in seven (8.3%) patients. In multivariate analyses, cardiovascular disease (OR 17.1, 95% CI 2.17-403) and renal transplant (OR 13.0, 95% CI 1.63-281) were risk-factors for a potassium decrease of >20%. Age >65 years (OR 11.6, 95% CI 1.89-224) was a risk-factor for diarrhoea lasting >2 days. Immunosuppression (OR 5.7, 95% CI 1.78-20.1) was a risk-factor for a creatinine increase of >10%. Norovirus infections in patients with underlying conditions such as cardiovascular disease, renal transplant and immunosuppressive therapy may lead to severe consequences typified by decreased potassium levels, increased levels of C-reactive protein and creatine phosphokinase. In the elderly, norovirus infection may lead to an increased duration of diarrhoea. Therefore patients at risk should be hospitalised early and monitored frequently. Strict preventional measures should be implemented as early as possible to minimise the risk of nosocomial outbreaks.
