An Unusual Case of Urinary Incontinence  [PDF]
Eric R. Anderson, Darius J. Unwala
Open Journal of Urology (OJU) , 2011, DOI: 10.4236/oju.2011.11001
Abstract: Urinary incontinence and hematuria are frequent complaints evaluated by urologists often with readily identifiable etiologies. Occasionally, an unlikely source is found. We present an unusual case of urinary incontinence and hematuria in an elderly female. Evaluation revealed that the complaints were due to a large cyst emanating from her right hip which was the result of a previous right hip arthroplasty in 1970 with three subsequent revisions. Her symptoms resolved spontaneously and the cyst has remained unchanged.
Assessing insulin effectiveness at the end of the day: Once-daily versus twice-daily insulin glargine injection  [PDF]
Mark R. Burge, Eric R. Schroeder, Stephen Mitchell
Journal of Diabetes Mellitus (JDM) , 2012, DOI: 10.4236/jdm.2012.22032
Abstract: Objective: Evidence supporting the twice-daily administration of insulin glargine as an approach to address its waning effectiveness at the end of a 24 hour period is sparse. We hypothesized that insulin concentrations determined during the last four hours of a 24 hour period would be greater when identical doses of insulin glargine were administered twice-daily as compared to once-daily among type 1 diabetes patients. Research Methods: Ten subjects with insulin deficient type 1 diabetes were admitted for two 38-hour studies at least one week apart. Patients received full-dose insulin glargine once daily at 0800 and half-dose insulin glargine twice-daily at 0800 and 2000 for at least one week in random order prior to overnight studies. Overnight glucose was stabilized with intravenous insulin on the evening prior to study, and subjects fasted and did not receive short acting insulin during the study period. Insulin concentrations were assessed every 30 minutes with an ultrasensitive assay between study hours 20 and 24. Results: Insulin concentrations for the final four hours of study period did not differ between once-daily and twice-daily insulin glargine administration (p = 0.38). Home glucose testing results and overnight plasma glucose concentrations did not differ between study conditions. Conclusions: These results demonstrate that insulin concentrations are equivalent during the last four hours of a 24-hour period when insulin glargine is administered once- or twice-daily. These findings do not support a role for twice-daily insulin glargine in the management of patients with type 1 diabetes.
The value of econometrics to economists in business and government: a study of the state of the discipline
Eric R. Sowey
Advances in Decision Sciences , 2002, DOI: 10.1155/s117391260200007x
Abstract: This paper is the first ever in-depth study of the econometric practice of quantitative economists outside academia. It goes further, to examine empirically the often-heard proposition that academic and nonacademic economists nowadays seem to analyse the same applied quantitative problems in markedly separate ways. Nine indicators of separation between the approaches of ‘town’ and ‘gown’ economists are developed. The study rests on detailed interviews with 50 nonacademic economists drawn widely from a single area of professional activity: the Australian housing sector. These economists' use of econometric methods, and their views on the value of these methods, are documented and compared with the academic approach to applied econometric work, as reported in the scholarly literature. The evidence on the nine indicators supports the existence of a state of separation. The paper points to some undesirable consequences of separation and concludes with practical ideas on what should be done about it. There are lessons in the findings of this study for the future of other quantitative disciplines that are widely practised in government, business and industry.
Terrorist bombings in Madrid
Eric R Frykberg
Critical Care , 2004, DOI: 10.1186/cc2997
Abstract: The authors confirmed the many consistent patterns to be expected following terrorist bombings, which virtually every other published series has documented [2,3]. The great majority of immediate survivors (1789/1885 [95%]) were not critically injured. As the authors state, this is best explained by the selection bias caused by the immediate death of most of those with critical injuries. Although it appears quite favorable that 14 of these 1885 immediate survivors (0.74%) subsequently died, it is important to recognize that this is deceptive because most casualties were not at all at risk for death. The death rate was correctly expressed in this report as a percentage of only the critically injured casualties who were truly at risk for death, and among whom all deaths occurred, resulting in a much heftier 'critical mortality' rate of 17% (14/82). This is a more accurate reflection of the quality of medical care given in such a mass casualty setting, and is a more accurate standard for comparison with other similar bombings. This critical mortality rate falls well within the range of all other terrorist bombing disasters, and lends itself to quality improvement analysis. The authors should be commended for applying the established objective measures of injury severity (Injury Severity Score, Acute Physiology and Chronic Health Evaluation II) to their patient population to allow this determination. I do agree that the two early emergency room deaths should be included in this figure because these patients were exposed to medical care.The injury patterns in this event were also typical of bombing disasters. Head, chest, abdominal, traumatic amputation and blast lung injuries predominated among the critically injured survivors, being the most common contributors to death; musculoskeletal and soft tissue wounds predominated among those who were not critically injured. Eardrum perforations and eye injuries were quite common but did not cause life-threatening problems.Over-

The Ambiguity of Reduction
Eric R. Scerri
Hyle : International Journal for Philosophy of Chemistry , 2007,
Abstract: I claim that the question of whether chemistry is reduced to quantum mechanics is more ambiguous and multi-faceted than generally supposed. For example, chemistry appears to be both reduced and not reduced at the same time depending on the perspective that one adopts. Similarly, I argue that some conceptual issues in quantum mechanics are ambiguous and can only be laid to rest by embracing paradox and ambiguity rather than regarding them as obstacles to be overcome. Recent work in the reduction of chemistry is also reviewed, including discussions of the ontological reduction of chemistry and the question of the emergence of chemistry from physics.
Some Aspects of the Metaphysics of Chemistry and the Nature of the Elements
Eric R. Scerri
Hyle : International Journal for Philosophy of Chemistry , 2005,
Abstract: There is now a considerable body of published work on the epistemology of modern chemistry, especially with regard to the nature of quantum chemistry. In addition, the question of the metaphysical underpinnings of chemistry has received a good deal of attention. The present article concentrates on metaphysical considerations including the question of whether elements and groups of elements are natural kinds. It is also argued that an appeal to the metaphysical nature of elements can help clarify the re-emerging controversies among chemists regarding the placement of the elements hydrogen and helium in the periodic system and the question of whether there exists a best form of the periodic table.

Recurrent hepatitis C virus after transplant and the importance of plasma cells on biopsy
Eric R Kallwitz
World Journal of Gastroenterology , 2013, DOI: 10.3748/wjg.v19.i2.158
Abstract: Hepatitis C virus (HCV) is the leading indication for liver transplantation in the United States. It recurs universally after transplant but the rate of fibrosis and the development of graft failure is variable. Different donor and recipient features have been demonstrated to impact fibrosis. Plasma cell hepatitis, a histologic finding, is one feature associated with poor graft and patient outcomes. The pathogenic mechanism resulting in plasma cell hepatitis is poorly understood, with evidence suggesting a role for both the HCV and the immune system.A recent publication described plasma cell hepatitis in a larger context of immune medicated graft dysfunction in transplant recipients receiving interferon based therapy. This manuscript will highlight the topic of plasma cell hepatitis and provide commentary on the lack of recognition, the data regarding pathophysiologic mechanisms and the potential management options.
