    BACKGROUND & AIMS: Various practice parameters have emphasized a step-wise approach to the treatment of asthma utilizing high doses of inhaled corticosteroids, i.e., 2000 ug per day for the most difficult-to-manage asthmatic patient, along with maximum bronchodilator therapy. The use of such vigorous therapy presupposes that various triggers that perpetuate asthma have been considered and hopefully eliminated or diminished, such as occupational incitants, gastroesophageal reflux, and concomitant medication such as beta blockers and perhaps difficult-to-recognize allergen stimulation. As new therapies emerge, their role in the treatment of a severe subgroup of the population remains uncategorized and will only be clarified with personal experience and appropriate double-blind studies. For example, there are data to support the concept that salmeterol plus moderate dose aerosol corticosteroids is superior to high dose corticosteroid aerosols. Theoretically, the use of anti-leukotrienes for a patient with aspirin idiosyncrasy may be superior to other combinations as would be conjectured from aspirin challenge data. Lidocaine has recently been employed in severe asthmatics, and preliminary data suggest benefit. The purpose of this review is to summarize some of our knowledge regarding medications that are either steroid-sparing or that might be useful in a subgroup of asthmatic patients with severe asthma.

    背景与目标: 各种实践参数强调了使用高剂量的吸入皮质类固醇治疗哮喘的逐步方法,即对于最难管理的哮喘患者,每天2000 ug,以及最大的支气管扩张剂治疗。使用这种剧烈疗法的前提是,已经考虑并希望消除或减少了使哮喘持续存在的各种诱因,例如职业性诱因,胃食管反流以及伴随药物 (例如 β 受体阻滞剂和可能难以识别的过敏原刺激)。随着新疗法的出现,它们在严重人群亚组治疗中的作用仍然未分类,只有通过个人经验和适当的双盲研究才能阐明。例如,有数据支持沙美特罗加中等剂量气雾剂皮质类固醇优于高剂量皮质类固醇气雾剂的概念。从理论上讲,阿司匹林特质患者使用抗白三烯可能优于其他组合,这可以从阿司匹林激发数据中得出。利多卡因最近被用于严重哮喘患者,初步数据表明有益。这篇综述的目的是总结我们有关保留类固醇或可能对患有严重哮喘的哮喘患者亚组有用的药物的一些知识。

    BACKGROUND & AIMS: :We report for the first time the possibility of weekly paclitaxel chemotherapy for a patient with advanced, nonresectable gastric cancer undergoing hemodialysis. A 50-year-old man with chronic renal failure due to bilateral polycystic kidneys, who had undergone hemodialysis three times a week for 5 years, presented with hematemesis in December 2004. Based on the diagnosis of gastric cancer with lymph node metastases, surgery was performed. On the 15th postoperative day, the patient was treated with chemotherapy using paclitaxel. Paclitaxel was administered at a dose of 60 mg/m2 as a 1 h iv infusion in 250 mL of saline. Hemodialysis was started 1 h after the completion of the paclitaxel infusion and was performed for 3 h. Paclitaxel was administered weekly on d 1, 8, and 15 on a 28-d cycle. The maximum plasma concentration of paclitaxel was 1390 microg/L. The area under the curve of paclitaxel was 4398.6 microg x h/L. Grade 2 leukopenia was encountered during the first cycle. The plasma concentrations of paclitaxel from 6 to over 24 h after the infusion were 0.01 to 0.1 micromol/L in our patient, and these concentrations have been shown to be effective on inhibiting the growth of gastric cancer cells without producing adverse side effects in the patient. The plasma concentration of paclitaxel was not influenced by hemodialysis. We conclude that the pharmacokinetics of paclitaxel is not altered in a patient with renal failure, and that weekly paclitaxel is a suitable treatment regimen for hemodialysis patients with advanced gastric cancer.
    背景与目标: : 我们首次报告了接受血液透析的晚期,不可切除的胃癌患者每周进行紫杉醇化疗的可能性。一名50岁的男子因双侧多囊肾而患有慢性肾功能衰竭,他每周接受3次血液透析,持续5年,2004年12月出现呕血。根据胃癌伴淋巴结转移的诊断,进行了手术治疗。术后第15天,患者接受紫杉醇化疗。紫杉醇以60 mg/m2的剂量在250 mL生理盐水中静脉输注1 h。紫杉醇输注完成后1小时开始血液透析,并进行3小时。紫杉醇每周在第1、8和15天的28天周期给药。紫杉醇的最年夜血浆浓度为1390 μ g/L。紫杉醇曲线下面积为4398.6 μ g × h/L。在第一个周期中遇到2级白细胞减少症。在我们的患者中,输注后6至24小时内紫杉醇的血浆浓度被0.01至0.1 micromol/L,并且这些浓度已被证明可有效抑制胃癌细胞的生长,而不会在患者中产生不良副作用。紫杉醇的血浆浓度不受血液透析的影响。我们得出的结论是,在肾功能衰竭患者中,紫杉醇的药代动力学没有改变,并且每周紫杉醇是晚期胃癌血液透析患者的合适治疗方案。

    BACKGROUND & AIMS: OBJECTIVE:To study the temporal relationships between cytomegalovirus (CMV) viral load and specific UL97 mutations in polymorphonuclear leukocytes (PMNL) and plasma samples from a patient with AIDS who developed ganciclovir-resistant CMV retinitis.

    METHODS:Sequential PMNL and plasma samples were analysed for determination of the CMV viral load using non-molecular methods and a quantitative polymerase chain reaction (PCR) assay. Screening of the same samples for the most common mutations conferring ganciclovir resistance was performed using nested PCR and restriction enzyme analysis.

    RESULTS:At the time of progression of CMV retinitis (after 6 months of ganciclovir), a rapid increase in the CMV DNA load was found in both PMNL and plasma samples. This increase paralleled the emergence of a specific mutation (V594) in the same samples and recovery of ganciclovir-resistant blood isolates. In this patient, however, the only tests that substantially predicted the progression of CMV disease were the quantitative PCR assay using PMNL and to a lesser extent the pp65 antigenemia assay.

    CONCLUSIONS:Quantitative evaluation of the CMV viral load in PMNL using sensitive assays such as PCR appears to be a promising approach for monitoring antiviral therapy in subjects with AIDS. In addition, common mutations conferring ganciclovir resistance can be detected directly in PMNL and plasma samples.

    背景与目标: 目标 : 研究巨细胞病毒 (CMV) 病毒载量与多形核白细胞 (PMNL) 和血浆样本中特定UL97突变之间的时间关系,该患者患有更昔洛韦耐药的CMV视网膜炎。
    方法 : 使用非分子方法和定量聚合酶链反应 (PCR) 分析方法分析了连续的PMNL和血浆样品,以确定CMV病毒载量。使用巢式PCR和限制性内切酶分析对相同样品进行了更昔洛韦抗性最常见突变的筛选。
    结果 : 在CMV视网膜炎进展时 (更昔洛韦6个月后),在PMNL和血浆样品中发现CMV DNA载量迅速增加。这种增加与同一样品中出现特定突变 (V594) 和更昔洛韦耐药血液分离株的回收平行。但是,在该患者中,唯一可以基本预测CMV疾病进展的测试是使用PMNL的定量PCR测定,以及在较小程度上使用pp65抗原血症测定。
    结论 : 使用敏感的检测方法 (例如PCR) 定量评估PMNL中的CMV病毒载量似乎是监测艾滋病患者抗病毒治疗的有希望的方法。此外,可以直接在PMNL和血浆样品中检测到赋予更昔洛韦抗性的常见突变。

    BACKGROUND & AIMS: :Health care workers' perceptions of patient suffering have not been well studied. Patients and health care workers were invited to answer a single, open-ended question. To develop a survey tool that could be validated and used for future research, what health care workers thought causes or caused the most suffering for patients was compared with what patients actually identified as the cause of their worst suffering. Health care workers underestimated loss and significantly underestimated physical nonpainful symptoms as causes of maximal suffering. Communication, emotional, and systems issues were often overestimated by health care workers. Health care workers may not accurately perceive what causes the worst suffering for patients. More studies are needed.
    背景与目标: : 医护人员对病人痛苦的看法没有得到很好的研究。邀请患者和医护人员回答一个开放式的问题。为了开发一种可以验证并用于未来研究的调查工具,将医护人员认为导致或导致患者最痛苦的原因与患者实际确定的最痛苦原因进行了比较。医护人员低估了损失,并大大低估了身体上的无痛苦症状,这是造成最大痛苦的原因。医护人员经常高估沟通,情感和系统问题。医护人员可能无法准确理解是什么导致了患者最严重的痛苦。需要更多的研究。

    BACKGROUND & AIMS: The dose, efficacy, and side effects of continuous intravenous infusion (CIVI) of morphine were compared with continuous subcutaneous infusion (CSCI) of morphine in patients with chronic cancer pain. Eligible patients were referred to the Palliative Care Program and were receiving a stable dose of CIVI of morphine. The design was a within-patient, one-way crossover; in which each patient provided data before and after a switch from CIVI to CSCI of morphine. "Rescue" doses were 50% of the hourly dose given every 2 hours as needed. Morphine was infused intravenously (i.v.) and subcutaneously (s.c.) via a McGaw/AccuPro Volumetric Infusion Pump. After baseline data, including side effects and pain assessment, were obtained, patients were evaluated twice daily for toxicity and analgesic efficacy. Those who had a stable CIVI dose for 48 consecutive hr were crossed over to the CSCI at the same dose as the intravenous (i.v.) phase. A stable dose was defined as no dose change, four or less rescue doses in the previous 24 hr, and a pain rating of none or mild. CIVI was considered equal to CSCI if these criteria were maintained for 96 consecutive hr. Fifty-seven patients were entered, and 40 were evaluable (15 women and 25 men). The median age was 67 (range 30-83 years). All 40 participants, after maintaining a stable dose throughout the i.v. phase, crossed to the s.c. phase and remained on s.c. for at least 48 hr. Thirty-two patients maintained a stable dose throughout the i.v. and s.c. phases. The mean stable i.v. dose (day 2) was 5.05 mg/hr, and the mean stable s.c. dose (day 4) was 5.7 mg/hr (P = 0.01). The mean number of rescue doses on day 2 was 0.83 per 24 hr versus 0.80 per 24 hours on day 4 (P = 0.6). The mean categorical pain score on day 2 was 0.83, and on day 4, 0.85 (P = 0.7). The mean visual analogue scale (VAS) on day 2 was 22.9 mm versus 17.6 mm on day 4 (P = 0.1). The mean incidence of side effects on day 2 was 1.7, and on day 4, 2.0 (P = 0.2). No patient was withdrawn or had a dose reduction due to unacceptable toxicity. There were two reports of local toxicity (mild erythema) at the SC needle insertion point, which required a site change. All of our 40 patients had adequate pain control with CIVI and CSCI morphine. Of the eight participants who were not maintained on the same i.v. and s.c. dose, all had adequate pain control and a similar side-effect profile on a higher s.c. morphine dose. These data suggest that the i.v. and s.c. routes are equianalgesic for most patients when administered as a continuous infusion. Pain control and side-effect profiles are quite similar and acceptable. s.c. morphine is an excellent alternative to i.v. morphine in both inpatients and outpatients requiring parenteral morphine for pain.

    BACKGROUND & AIMS: BACKGROUND:A large insurer in Hawaii mails annual reminders to its members regarding recommended health screenings. This study examined the associations between the characteristics of physicians visited after the reminders were sent and the health screenings received for breast, cervical, and colorectal cancers, and for diabetes and cholesterol. METHODS:The study population included members identified as needing health screenings from 2000 to 2003 based on age and gender criteria. The study used a longitudinal design focusing on the 12 months after reminders were sent. Data were analyzed using logistic regression examining physician visits, other health services, and receipt of health screenings by 1-month intervals subsequent to the reminder mailings. RESULTS:In adjusted, multivariable models, members who saw physicians they had not seen in the past year had odds ratios for obtaining health screenings 6 to 8 times higher than members who only saw previously visited physicians. This enhanced response occurred among members receiving their first, second, and third (or subsequent) annual reminder letter. The more physicians that were visited and who were new to the members, the more likely the members were to obtain health screenings. CONCLUSIONS:Members seeing physicians they had not seen in the past year had significantly higher screening rates than the members only seeing physicians they had previously visited. The results suggest that healthcare screening may receive less attention at repeat visits with a physician than at visits with a physician who is new to a member.

    BACKGROUND & AIMS: BACKGROUND:Side-stream spirometry offers a non-invasive method to monitor continuously respiratory mechanics in intubated patients. We studied the effects of different positions on dynamic lung compliance during anaesthesia. METHODS:The study consisted of 56 patients, operated in supine, prone, kneeling or lateral park-bench position. Dynamic lung compliance and inspiratory peak pressure were recorded after induction of anaesthesia, 15 min and 1 h after posturing the patient. RESULTS:The first measured compliances were comparable in all groups. The compliance in the lateral and the prone positions was significantly lower than in the supine position at 15 min (P < 0.01) and 1 h (P < 0.001) after the posture change. The peak inspiratory pressure was significantly lower in the kneeling position than in the other groups (P < 0.01 at the first measurement, P < 0.001 at the later measurements). No correlation was found between body mass index and compliance. CONCLUSION:We found that dynamic lung compliance decreased significantly upon change of posture from supine to lateral or prone position, whereas in the kneeling position no change in compliance was observed. We suggest that the kneeling position might be preferable to the prone position.

    BACKGROUND & AIMS: The accuracy of cervicovaginal fetal fibronectin as a predictor of preterm birth was studied in patients with increased risk for preterm delivery (according to the Creasy-score). In a prospective blind observational study the smear from the posterior fornix vaginae of 56 pregnant patients without PROM was examined using a quantitative immunoassay for the detection of fetal fibronectin. The patients who tested positively for fetal fibronectin had significantly more preterm deliveries than those with a negative result (CHI square-test, p < 0.01, RR 5.1). Overall, sensitivity, specificity, positive and negative predictive values were 56%, 87%, 45% and 91%, respectively. In patients with preterm labor these values were 75%, 87%, 60%, and 93%, respectively. No patient with a negative result delivered preterm during the following two weeks. It is concluded that performing the fetal fibronectin test in patients with preterm labor is useful for the prediction of preterm birth. Routine testing in patients at increased risk (asymptomatic patients) is not recommended for lack of effectiveness.

    BACKGROUND & AIMS: Environmental pollution has become a major concern for the future of life on our planet; medical care, especially in hospitals, contributes significantly to this pollution. The increasing usage of highly-developed medical devices, drugs and disposable products are a drain on natural resources as well as financial ones. In this situation, it is a major task for hospital epidemiologists to maintain high standards of hygiene while reducing environmental pollution, reducing consumption of limited natural resources, and minimizing costs. The reduction of hospital waste, the control of polluting and toxic emissions, the avoidance of unnecessary disinfection procedures and disposables, the implementation of energy and water saving technologies are practicable measures in hospital ecology. To realize a sustainable development within hospitals, it is necessary that the need to maintain a balance between effective infection control and a good ecological environment is recognized and supported by health-care workers and the hospital management.

    背景与目标: 环境污染已成为地球生命未来的主要问题; 医疗保健,尤其是医院的医疗保健,对这种污染有很大影响。高度发达的医疗设备,药品和一次性产品的使用日益增加,既消耗了自然资源,也消耗了金融资源。在这种情况下,医院流行病学家的主要任务是在减少环境污染的同时保持高标准的卫生,减少对有限自然资源的消耗并最大程度地降低成本。减少医院废物,控制污染和有毒排放物,避免不必要的消毒程序和一次性用品,实施节能节水技术是医院生态中的可行措施。为了实现医院内部的可持续发展,有必要在有效的感染控制和良好的生态环境之间保持平衡的需要得到医护人员和医院管理层的认可和支持。

    BACKGROUND & AIMS: :The adoption of information technology in patient care has become a trend in healthcare organizations. The impact of this technology on end users has been widely studied, but little attention has been given to its influence from a management perspective. The purpose of this study was to explore nurse managers' perceived experiences in implementing a policy to adopt personal digital assistant technology. A descriptive, exploratory qualitative approach (one-on-one, in-depth interviews) was used to collect data from 16 nurse managers of inpatient units at a medical center in Taiwan. Interview data were analyzed according to Miles and Huberman's data reduction, data display, and conclusion verification process. The results revealed that nurse managers experienced the limitations of technology, training issues, doctors' obstructive influence, role conflict, and improvement of future personal digital assistant use. These results can be used to improve strategic organizational planning and in-service training programs to implement information systems.

    BACKGROUND & AIMS: :Inborn errors of vitamin B(12) (cobalamin) metabolism are characterized by decreased production of active cobalamin cofactors and subsequent deficiencies in the activities of methionine synthase and methylmalonyl-CoA mutase. With the recent discovery of the cblJ defect in two patients with phenotypes mimicking the cblF defect, there are nine genes known to be involved in cobalamin metabolism. The new defect is caused by mutations in the ABCD4 gene, encoding an ABC transporter. At the moment, there is no clear distinction between the cblJ and cblF defects either clinically or biochemically, and both defects result in blocks in the transport of cobalamin from the lysosome to the cytoplasm. A patient was diagnosed with hyperhomocysteinemia and methylmalonic aciduria at the age of 8 years. Incorporations of both [(14)C]propionate and [(14)C]methyltetrahydrofolate in cultured fibroblasts were within reference ranges and thus too high to allow for complementation analysis. We observed decreased synthesis of both adenosylcobalamin and methylcobalamin and accumulation of unmetabolized cyanocobalamin. Exome sequencing was performed to identify causative mutation(s) and Sanger re-sequencing was performed to validate segregation of mutation in the family. By this approach, a homozygous mutation, c.423C>G, in the ABCD4 gene was identified. Here, we report the successful application of exome sequencing for diagnosis of a rare inborn error of vitamin B(12) metabolism in a patient whose unusual presentation precluded diagnosis using standard biochemical and genetic approaches. The patient represents only the third known patient with the cblJ disorder.

MATERIALS AND METHODS:One-thousand eight-hundred and twenty-two patients were stratified into the three GEC-ESTRO categories of "good candidates", "possible candidates" and "contraindication" in order to assess outcomes. RESULTS:All the 1822 cases except 7 could be classified according to GEC-ESTRO groups: 573 patients met the criteria to be included in the "good candidates" group, 468 patients in the "possible candidates" group and 767 patients in the "contraindication" group. Median and mean follow-up length was 3.5 years (range 0-10.5 years) and 3.8 years (SD 2.2), respectively. The 5-year rate of in-breast tumor reappearances for "good candidates", "possible candidates" and "contraindication" groups were 1.9%, 7.4% and 7.7%, respectively (p 0.001). While the regional node relapse showed no difference, the rate of distant metastases was significantly different in the "contraindication" group compared to the other two categories, having a significant impact on survival. CONCLUSIONS:Among the ELIOT population, the GEC-ESTRO recommendations enabled the selection of the good candidates with a low rate of local recurrence, but failed to differentiate the "possible candidates" and the "contraindication" groups.
