Psychotropic drug intake in residents newly admitted to nursing homes

While several surveys have shown that psychotropic drugs are frequently used by nursing home residents, no studies have been performed to investigate whether the rates of drug use increase during the stay in nursing homes or whether residents have taken these drugs already before admission. Therefore, we investigated 262 residents admitted to rural and urban nursing homes in Austria for prevalence of psychotropic drug intake before admission, shortly after admission, and 6 months later. Two weeks after admission, 72.1% of the residents were being treated with psychotropics, while 6 months later 79.0% were receiving these drugs. The significantly higher rates of psychotropic drug use among the psychiatrically ill and in those suffering from sleeping problems suggest that these drugs were prescribed aptly, but residents without appropriate criteria for drug intake were often also treated with psychotropics. During 3 months before admission to nursing homes, 45.5% of the sample reported having taken psychotropics. In more than half of residents without drug intake before admission, psychotropic treatment was initiated within the first 2 weeks after admission, while during the first 6 months after admission the rate of drug use increased only slightly. This suggests that a large percentage of psychotropic intake is due to nursing home orders. Received: 20 January 1997/Final version: 21 May 1997     

Antiepileptic drug toxicity: Definition and mechanism of action

A detailed review of the adverse reactions of anticonvulsants is given, focusing on the definitions of drug toxicity, sources of information, patterns of durg utilization, pharmacokinetic variables and different mechanisms of action. The information available in the literature provides a wide spectrum of drug toxicity with no attempt at a practical definition of the reported events. This favors uncertainty among practising physicians, who are led to use the individual items with different attitudes. Suggestions are given for the evaluation, prevention and treatment of anticonvulsant drug toxicity.

Sommario La presente è una revisione critica dei diversi aspetti della tossicità dei farmaci antiepilettici. L'analisi della letteratura è condotta con particolare riferimento alle diverse fonti di informazione, ai pattern di utilizzo dei singoli principi attivi, ai dati farmacocinetici ed ai meccanismi di azione farmacologica sottostanti. L'ampio panorama che ne deriva non consente una definizione pratica degli effetti indesiderati degli anticonvulsivanti. Ciò determina incertezza e confusione nella pratica medica, con conseguente diversità di comportamenti. La rassegna si conclude con la presentazione di alcuni suggerimenti pratici per la valutazione, la prevenzione ed il trattamento della tossicità da anticonvulsivanti.

     

革兰氏阴性杆菌发生过程控制的研究

本研究选择奇异变形杆菌和绿肿杆菌等作为实验体系，从群体发生发展过程的宏观表现上探讨了生物控制的时空表达及非线性问题。结果表明，杆菌发生过程的时相周期性可以表现为空间的波形靶图样，并具有分形的特征。实验结果表明，菌群在生长过程中的代谢产物是富含生物信息的控制中介机制。我们认为，生物系统局部存在着准平衡和准封闭的微生态环境，生物液晶的存在和相变是细菌群体发生过程的重要协同中介因素。

Surgical treatment of patients with psychiatric disorders: A review of 21 patients

Between January 1985 and September 1994, 21 patients with psychiatric disorders underwent various forms of surgery at our hospital. There were 12 men and 9 women with an average age of 57.6 years. The coexisting psychiatric disorders were schizophrenia in 15 patients, depression in 2, dementia in 2, mental retardation with epilepsy in 1, and Parkinson's disease in 1. All the patients had been receiving neuroleptic medications for a long period. The indications for surgery were: cholelithiasis in 6 patients, acute appendicitis in 4, perforation of the small intestine in 3, incarceration of an inguinal hernia in 2, and esophageal cancer, stomach cancer, bleeding from a gastric ulcer, perforation of a duodenal ulcer, strangulating ileus, and burns in 1 patient each, respectively. All of the patients who underwent elective surgery were given epidural anesthesia with or without general anesthesia. Antipsychotic medications were given until just prior to surgery and recommenced concurrent with the first meal. Abnormal behavior was observed in 11 patients (52.4%) postoperatively, but all the patients were discharged in accordance with recovery from their surgical disorder. Intra- and postoperative hypotension resistant to intravenous catecholamine administration was recognized in 9 patients (42.9%), and this peculiar complication should be borne in mind when patients with psychiatric disorders require surgical management.

免疫接种服务中一次性注射器处理方法及成本分析

利用山东省和陕西省现场调查资料,分析了2省不同层次医疗机构的一次性注射器的处理方式,并通过计算不同处理方式的成本,提出具有成本效果的一次性注射器的处理方式。结果表明:消毒/毁形、焚烧、掩埋和回收是主要的处理方法,在被调查的所有医疗机构中,没有一家医疗机构使用安全盒处理使用过的一次性注射器。由于没有使用规定的焚烧设备,实际调查结果表明,焚烧和掩埋的处理成本相对较低,是目前在村卫生室水平最适合的一次性注射器处理方法,而对于乡级和县级卫生机构而言,消毒/毁形和回收是目前较为适宜的处理一次性注射器的方法。
