We present a 3-year review of clinical paediatric experience with the Statscan (Lodox Systems, Johannesburg, South Africa), a low-dose, digital, whole-body, slit-scanning X-ray machine. While focusing on the role of the unit in paediatric polytrauma, insight into its applications in other paediatric settings is provided.
BACKGROUND The global demand for diagnostic imaging exceeds the supply of radiologists and is of particular significance in poorly resourced healthcare environments where many radiographs are unreported. Delayed or absent reporting may negatively impact patient management. In well-resourced countries there is recognition that extending the role of(More)
BACKGROUND Conventional chest radiographs do not afford consistently good visualisation of the main bronchi and sub-carinal angle. Improved visualisation would facilitate accurate measurement of the airways, definition of normal radiographic anatomy and, possibly, earlier identification of extrinsic compression or displacement. AIM The main objective of(More)
AIM To describe the clinical presentation and outcomes of hospitalised patients infected with human metapneumovirus (hMPV) and human respiratory syncytial virus (hRSV) in a tertiary hospital in Cape Town, South Africa. METHODS hMPV was identified in 17 respiratory specimens submitted for viral studies during the period 2001-2003. These patients' medical(More)
Crop plants genetically modified for herbicide tolerance were some of the first to be released into the environment. Frequently, the cauliflower mosaic virus (CaMV) 35S promoter is used to drive expression of the herbicide tolerance transgene. We analyzed the response to CaMV infection of a transgenic oilseed rape line containing the bialaphos tolerance(More)
BACKGROUND There is limited knowledge of chest radiographic abnormalities over time in HIV-infected children in resource-limited settings. OBJECTIVE To investigate the natural history of chest radiographic abnormalities in HIV-infected African children, and the impact of antiretroviral therapy (ART). METHODS Prospective longitudinal study of the(More)
BACKGROUND Anorectal malformations are often associated with rectal pouch fistulas. Surgical correction requires accurate evaluation of the presence and position of such fistulas. Fluoroscopy is currently the chosen modality for the detection of fistulas. The role of MRI is unexplored. OBJECTIVE To compare the diagnostic accuracy of MR versus fluoroscopic(More)
BACKGROUND Neurosurgeons are familiar with the challenges presented by craniopagus twins, but other types of conjoined twins may also have neurosurgical implications. We report our experience in the management of ischiopagus and pygopagus conjoined twins. METHODS This is a retrospective review of the management of conjoined twins at Red Cross Children's(More)
INTRODUCTION Tuberculous (TB) meningitis is sometimes difficult to diagnose in young children. The decision to start anti-TB treatment of TB meningitis is usually made on clinical grounds and results of special investigations, such as cerebrospinal fluid examination and cranial computerized tomography (CT), because bacteriologic yield is low and the results(More)
OBJECTIVE To investigate the effect of closed-system vs. open endotracheal suctioning on the frequency of ventilator-associated pneumonia and outcome in a pediatric intensive care unit in a developing country. DESIGN Prospective observational and nonrandomized controlled clinical study. SETTING A 20-bed pediatric intensive care unit in a tertiary(More)
