The study was undertaken to determine the prevalence and clinical importance of alternative causes of symptoms discovered in patients undergoing flank pain protocol (FPP) computed tomography (CT) scans in patients with classic symptoms of kidney stone (flank pain, back pain, or both) without evidence of urine infection. ⋯ While a non-kidney stone cause for a patient's symptoms are found in nearly 10% of CTs done using a FPP, acutely important findings occur in less than 3% of scans done in patients with flank or back pain and absence of pyuria.

The authors describe national trends in use, reasons for visit, most common diagnoses, and resource utilization in patients admitted to intensive care units (ICUs) from hospital-based emergency departments (EDs) in the United States. ⋯ Intensive care unit admissions from EDs are increasing at a greater rate than both population growth and overall ED visits. ED resource use, specifically advanced diagnostic imaging, has increased markedly among ICU admissions. While mean ED and hospital LOS have not changed significantly, the mean ICU admission spends over 5 hours in the ED prior to transfer to an ICU bed. A greater emphasis on the ED-ICU interface and critical care delivered in the ED may be warranted.

Emergency medicine (EM) is emerging worldwide. Its development as a recognized specialty is proceeding at difference rates in different countries. Europe is a region with complex political affiliations and is composed of countries both within and outside the European Union (EU). ⋯ The European Union of Medical Specialists requires that once two-fifths of countries acknowledge a specialty, all EU countries must address the question. EM had achieved the needed majority by 2011. This article briefly describes the European road to specialty acceptance.

Patients sustaining rattlesnake envenomation often develop thrombocytopenia, the etiology of which is not clear. Laboratory studies have demonstrated that venom from several species, including the Mojave rattlesnake (Crotalus scutulatus scutulatus), can inhibit platelet aggregation. In humans, administration of crotaline Fab antivenom has been shown to result in transient improvement of platelet levels; however, it is not known whether platelet aggregation also improves after antivenom administration. ⋯ Crotaline Fab antivenom improved platelet aggregation in an in vitro model of platelet dysfunction induced by venom from C. scutulatus. It is unclear at this time whether this improvement in platelet dysfunction translates into improved clinical outcomes in envenomated patients.
