Effectiveness of an algorithm in reducing the number of unnecessary ultrasound scans for deep vein thrombosis: an evaluation report.

Introduction: Patients with suspected deep vein thrombosis (DVT) pose a diagnostic dilemma to the Emergency Department (ED) clinician. This study aimed to implement a known algorithm incorporating the modified Wells criteria and D-dimer testing to guide the ED clinician, thus reducing unnecessary ultrasound scans (USS).

Methods: Patients who presented to the ED between August 2008 and April 2009 with suspected DVT underwent Wells scoring.

Effects of a 12-week exercise training programme on aerobic fitness, body composition, blood lipids and C-reactive protein in adolescents with obesity.

Introduction: Developing effective exercise programmes for the paediatric population is a strategy for decreasing obesity and is expected to help in eventually limiting obesity-associated long-term health and societal impact. In this study, the effects of a 12-week twice weekly additional exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises, in additional to typical physical education sessions, on aerobic fitness, body composition and serum C-reactive protein (CRP) and lipids were analysed in 13- to 14-year-old obese boys contrasted with a control group.

Materials And Methods: Both the exercise group (EG, n = 12) and control group (CG, n = 12) participated in the typical 2 sessions of 40-minute physical education (PE) per week in schools, but only EG participated in additional 2 sessions per week of 45 to 60 minutes per session of exercise training, which comprised a combination of circuit-based resistance training and aerobic exercises maintained at 65% to 85% maximum heart rate (HRmax = 220 - age).

Radiographic features of SARS in paediatric patients: a review of cases in Singapore.

Introduction: Severe acute respiratory syndrome (SARS) is a newly emerged atypical pneumonia caused by the SARS-associated coronavirus (SARS-CoV). Chest radiographic appearances have been reported as non-specific, ranging from normal to peribronchial thickening and ill-defined airspace shadowing. This study is a retrospective review of chest radiographic findings in children with suspected and probable SARS during the 2003 outbreak in Singapore.

Severe acute respiratory syndrome (SARS): chest radiographic features in children.

Background: Severe acute respiratory syndrome (SARS) is a recently recognized condition of viral origin associated with substantial morbidity and mortality rates in adults. Little information is available on its radiologic manifestations in children.

Objective: The goal of this study was to characterize the radiographic presentation of children with SARS.
