Background: Blood cultures (BCs) are obtained to identify etiologic organisms, demonstrate antibiotic efficacy, determine duration of treatment, and/or suggest further interventions. Published guidelines do not clearly state indications and timing for obtaining BCs. As a result, clinicians may obtain too many BCs, increasing cost and patient discomfort. Objective: To determine frequency of BCs performed at our hospital as part of a quality improvement project. Design: Retrospective review of all BCs submitted during a randomly selected month. Setting: A New York City 535-bed, university-affiliated community hospital. measurements: Patient demographics and BC data were obtained from medical and laboratory records. Results: During the selected month, 2280 BCs were performed for 379 patients. Negative BCs were seen in 221 patients (58%) with one-half having multiple BCs performed within 48 hours of admission and prior to obtaining results of initial BCs. Repeat BCs frequently did not reveal further pathogens among patients with either negative or positive initial BCs. Conclusions: Two-thirds of BCs were obtained from less than one-half of patients without added clinical utility. Often, BCs were repeated prior to results of initial BCs or repeated in patients receiving antibiotics in spite of known low yield following antibiotic initiation. Clinical assessment and review of initial BCs prior to obtaining further BCs is necessary. Staff education regarding appropriate clinical setting for BCs and indications for repeat BCs is required to maximize utilization of resources, improve diagnostic yield, and limit patient discomfort.

背景:胆碱能性荨麻疹(CholU)是慢性诱导性荨麻疹的一种常见形式,其临床主要表现为在遇热或运动出汗后等情况下出现临床症状。乙酰胆碱(ACh)被认为可诱发CholU,但其作用和相关性并不明确。ACh在皮肤中通过其受体CHRm3发挥作用,并被乙酰... 详细信息

背景:胆碱能性荨麻疹(CholU)是慢性诱导性荨麻疹的一种常见形式,其临床主要表现为在遇热或运动出汗后等情况下出现临床症状。乙酰胆碱(ACh)被认为可诱发CholU,但其作用和相关性并不明确。ACh在皮肤中通过其受体CHRm3发挥作用,并被乙酰胆碱酯酶(AchE)降解。到目前为止,尚未有报道关于CHRm3和AChE在CholU患者的皮肤中表达。目的 :与健康对照受试者(HC)相比,评估CHRm3和AchE在CholU患者的皮损和非皮损处的表达。患者和方法 :对CholU患者(n=13)评估他们对脉冲控制测试(PCE)出汗时间和他们的CholU的临床特征的关系。对PCE测试前后钻取非皮损和皮损处活检进行CHRm3和AChE染色,并通过定量组织形态学分析。HC的皮肤切片用作对照。结果 :与HC的皮肤相比,CholU患者的非皮损处AchE的阳性明显表达降低。CHRm3染色结果类似。与非损伤皮肤相比,CholU患者的皮损的阳性表达并无明显改变。但是HC中,在PCE测试前后AchE的表达获得了显着差异,CHRm3并无明显统计学差异。结论 :我们的结果表明,CholU患者的皮肤中AchE和CHRm3数量减少。特别是对于严重减少汗液的CholU患者。需要进一步的研究来阐明CholU患者的AchE和CHRm3水平是否与疾病活动有关,以及皮肤AchE和酰胆碱受体是否响应CholU的有效治疗或自发缓解而增加。

通过金属套管测量地层地层电阻率能使常规水饱和度评价方法用于产层，这种技术在几种场合下可以使用，尤其在根据脉冲中子读数估算水饱和度有疑问的低孔隙度环境中可以使用，然而，研制过金属套管测量地层电阻率仪器的工作遇到了几个重大的技术与科学问题，Baker Atlas与石油公司和天然气研究所合作研制了一种过套管电阻率仪器(TCR),顺现场条件下已成功地完成了几次测试，过套管地层电阻率读数与裸眼井测井曲线十分一致，对套管缺陷和接箍的补偿十分成功。

测量过金属套管后的地层电阻率可以把公认的含水饱和度评价方法用于生产层。这种新技术可广泛应用，尤其适用于脉冲中子读数出现问题的低孔隙度地层，然而，设计一套能测量过金属套管的地层电阻率仪器要面临多种重大的科学和技术的难题。通过与油气研究中心（GRI）领导的油公司财团合作，Baker Atlas已经开发了一种过套管电阻率仪，这种仪器在野外已进行了多次成功测试，过套管地层电阻率曲线与裸眼井测井曲线非常近似，套管损伤和接箍所产生的影响可得到成功的补偿。
