Impact of 24-hour specialist coverage and an on-site CT scanner on the timely diagnosis of acute aortic dissection.

Introduction: Acute aortic dissection (AAD) is a rare and potentially fatal condition that has been known to be missed in diagnoses. Our primary objective was to determine if the availability of 24-hour emergency department (ED) specialist coverage and an on-site computed tomography (CT) scanner reduced the rate of missed diagnoses of AAD.

Methods: We selected records of patients diagnosed with dissection of the aorta from a hospital's discharge database and death register in the period of January 1998 to December 2014.

Clinical Decision Rules for Paediatric Minor Head Injury: Are CT Scans a Necessary Evil?

Introduction: High performing clinical decision rules (CDRs) have been derived to predict which head-injured child requires a computed tomography (CT) of the brain. We set out to evaluate the performance of these rules in the Singapore population.

Materials And Methods: This is a prospective observational cohort study of children aged less than 16 who presented to the emergency department (ED) from April 2014 to June 2014 with a history of head injury.

Body Mass Changes Across a Variety of Running Race Distances in the Tropics.

Background: Current literature evaluating body mass (BM) changes across a variety of running race distances is limited. The primary objective of this study was to profile the range of BM changes across race distances. The secondary objective was to evaluate the prevalence of exercise-associated hyponatremia (EAH) in runners admitted to the on-site medical tent following participation of race events of different distances.
