Acinetobacter baumannii is emerging as a major cause of nosocomial infections particularly in high risk patients. Being resistant to adverse environmental
conditions, it can stay for prolonged periods in the hospital environment. We report an outbreak in the medical oncology ward
where nine patients suspected of bacteraemia were blood culture positive forA. baumannii from the two samples each, one collected through the i.v. cannula and another through the peripheral venous puncture. The
bacteria was also isolated from the environmental sources from the various samples collected. The biotype, antibiogram, cellular
protein profiles on SDS-PAGE and the restriction enzyme analysis patterns of the patient isolates and the environmental isolates
were similar. This points to the environment as a source of infection. With reinforcement of proper barrier nursing and use
of disposable heparine ampoules it was possible to control the outbreak. 相似文献

Purpose: A new technique is presented for in vivo measurements of the dose equivalent from photoneutrons produced by high-energy radiotherapy accelerators.Methods and Materials: The dosimeters used for this purpose are vials of superheated halocarbon droplets suspended in a tissue-equivalent gel. Neutron interactions nucleate the formation of bubbles, which can be recorded through the volume of gel they displace from the detector vials into graduated pipettes. These detectors offer inherent photon discrimination, dose-equivalent response to neutrons, passive operation, and small sensitive size. An in vivo vaginal probe was fabricated containing one of these neutron detector vials and a photon-sensitive diode. Measurements were carried out in patients undergoing high-energy x-ray radiotherapy and were also repeated in-phantom, under similar irradiation geometries.Results and Conclusion: Neutron doses of 0.02 Sv were measured in correspondence to the cervix, 50 cm from the photon beam axis, following a complete treatment course of 46.5 Gy with an upper mantle field of 18-MV x-rays. This fraction of dose from neutrons is measured reliably within an intense photon background, making the technique a valid solution to challenging dosimetry problems such as the determination of fetal exposure in radiotherapy. These measurements can be easily carried out with tissue-equivalent phantoms, as our results indicate an excellent correlation between in vivo and in-phantom dosimetry. 相似文献

医学气象学与SARS流行的相关性研究 总被引:2,自引:0,他引:2
目的从医学气象学角度探讨SARS流行与气象因素的相关性。方法以SARS高发区广州、北京为例,通过网络、报刊等媒介获取两地在SARS流行前后的相关气象因子(日最高温度、日最低温度、相对湿度)及SARS疫情报告,运用EXCEL2000及相关矩阵法统计分析气象因子与SARS流行的关系,并从医学气象学角度对其相关性作出探讨。结果①SARS在12.8~23.5℃发病率最高,且与最高温度呈负相关。②SARS发病与最低温度呈负相关,高发前期有明显的降温过程。③广州的相对湿度较北京高,但与SARS的流行相关性不大。④2001年冬平均气温高于往年。结论①相对湿度较大有利于SARS的发生。②SARS发生于温热天气,气温波动有助于其流行。③气候异常变化是SARS发生的诱因。 相似文献

INTRODUCTION: The safety and efficacy of medications stored on air medical helicopters may be adversely affected by extreme temperatures. The purpose of this study was to determine whether temperatures inside an air medical helicopter drug box were within the U.S. Pharmacopeia recommendations for controlled room temperature. This is defined as a temperature between 15 degrees and 30 degrees C (59 degrees and 86 degrees F) with a mean kinetic temperature of less than 25 degrees C (77 degrees F). An additional goal was to determine whether time/temperature indicator labels can reliably monitor mean kinetic temperatures. METHODS: Temperatures were monitored with miniature electronic temperature recorders and color-changing time/temperature indicator labels. RESULTS: The mean kinetic temperatures for the summer and winter periods were 25.1 degrees C (77.2 degrees F) and 12.7 degrees C (54.8 degrees F), respectively. In the summer, the electronic recorders logged temperatures exceeding 25 degrees C (59 degrees F) 37% of the time and more than 30 degrees C (86 degrees F) 6% of the time. In the winter, temperatures less than 15 degrees C (59 degrees F) were recorded 83% of the time. The mean kinetic temperatures obtained from the electronic recorder and the time/temperature indicator labels differed by less than 0.7 degree C (1.3 degrees F). The results show that medications on an air medical helicopter are subject to temperatures out of the recommended range and that time/temperature indicator labels can reliably monitor mean kinetic temperatures. 相似文献

The objectives of this study were to survey the prevalence of medical disorders in Chinese women with endometrial carcinoma and evaluate their potential impact on the clinical treatment and prognosis. Three hundred and seven women with endometrial carcinoma, from July 1, 1971 to October 31, 2001, were analyzed retrospectively. One hundred and forty-six of them (47.6%) were found to have associated medical disorders. The most common medical disorders were hypertension (33.9%), diabetes mellitus (9.8%), and coronary heart disease (9.4%). As many as 38.4% of the women had two or more medical disorders. The patients with medical disorders were on average elder than those without any medical disorders (P < 0.01). Radiotherapy and chemotherapy were administered more commonly in the group with medical disorders than in the one without (P < 0.01). The rate of surgical procedures was significantly lower in the group with medical disorders than in the group without (P < 0.01). However, the extent of surgical interventions was similar in both groups (P > 0.05). The occurrence of medical disorders was independent of the tumor stage, grade, and histological types (P > 0.05). In addition, follow-up data showed that the 3-year and 5-year survivals were not influenced by the medical disorders (P > 0.05). The results thus suggest that Chinese women with endometrial carcinoma have frequently concurrent medical disorders. Selection of treatment strategies can be influenced by these associated medical disorders, but the overall survival is little changed. 相似文献
