Variability in the management and imaging use in paediatric minor head trauma in European emergency departments. A Research in European Pediatric Emergency Medicine study.

OBJECTIVE: The objective of the study was to assess the variability in the management of paediatric MHT in European emergency departments (EDs). METHODS: This was a multicentre retrospective study of children ≤18 years old with minor head trauma (MHT) (Glasgow Coma Scale ≥14) who presented to 15 European EDs between 1 January 2013 and 31 December 31. Data on clinical characteristics, imaging tests, and disposition of included patients were collected at each hospital over a 3-year period. RESULTS: We included 11 212 patients. Skull radiography was performed in 3416 (30.5%) patients, range 0.4-92.3%. A computed tomography (CT) was obtained in 696 (6.2%) patients, range 1.6-42.8%. The rate of admission varied from 0 to 48.2%. CONCLUSION: We found great variability in terms of the type of imaging and rate of CT scan obtained. Our study suggests opportunity for improvement in the area of paediatric head injury and the need for targeted individualised ED interventions to improve management of MHT.

Selective fatty acid release from intracellular phospholipids caused by PCBs in rat renal tubular cell cultures.

The purpose of this study was to explore the influence of different polychlorinated biphenyls (PCBs) upon the release of oleic and palmitic acid from the intracellular lipids, which were previously labeled with [3H]oleic or [3H]palmitic acid, respectively. Studies have been realized with Aroclor 1248 (a commercial PCB mixture with 48% chlorine by weight), and two pure PCB congeners: 3,3',4, 4'-tetrachlorobiphenyl (a non-ortho-substituted planar congener) and 2,2',4,4',5,5'-hexachlorobiphenyl (a di-ortho-substituted nonplanar congener). The treatment of cells with Aroclor 1248 increased [3H]oleic acid release in a concentration-dependent manner. Our results showed that only the di-ortho-substituted congener which prefers a nonplanar configuration stimulated the release of [3H]oleic acid from the intracellular phospholipids to the culture medium, while the exposure of cell cultures to the chosen non-ortho-substituted coplanar congener did not alter the release of [3H]oleic acid to the culture medium. Finally, none of the PCBs studied could increase the release of [3H]palmitic acid from the intracellular stores significantly. The possibility that these differential alterations in the fatty acid release affect cell function during PCB exposure should therefore be postulated.

Cultural diversity in an undergraduate nursing curriculum: an overview.

The total percentage of ethnic groups in the general U.S. population continues to grow. Nurse educators must meet the responsibility of preparing a culturally competent workforce. This article will describe the incorporation of cultural concepts and transcultural nursing in an undergraduate baccalaureate nursing curriculum at a private liberal arts college located in suburban New York.
