ReviewRole of radiology in the treatment of malignant hilar biliary strictures 1: review of the literature.
Malignant strictures of the biliary tree are an uncommon cause of obstructive jaundice. There are a number of pathological subtypes, but tumours in this region tend to have similar clinical and diagnostic features and therapeutic and prognostic implications. We review the published literature on this topic discussing diagnostic modalities and treatment options with a focus on radiological intervention. ⋯ There is little firm evidence to suggest that any one palliative modality is superior. Interventional radiology is particularly suitable for palliative management of difficult and expansive lesions as the anatomy can preclude easy access by surgical or endoscopic techniques. Good palliative results with minimal mortality and morbidity can be achieved with percutaneous stenting.

ReviewPaediatric radiotherapy in Australia and New Zealand: an anachronism in 2003?
This report reviews the activities of the Paediatric Special Interest Group of the Royal Australian and New Zealand College of Radiologists in terms of its involvement with the Australian and New Zealand Children's Cancer Study Group and its research and educational activities. Examples of when and how radiotherapy is currently used in the management of paediatric malignancies are provided. Some thoughts for the future of both paediatric radiotherapy and our subspecialty are also presented.

The aims of the present study were to determine the rate of misinterpretation of non-contrast cranial CT scans by emergency specialists and trainees compared with specialist radiologists, and the proportion of misinterpretations that is consequential. A 12-month prospective blinded cohort study was performed. One-hundred and ninety of 1,282 scans (14.8%) were misinterpreted, and 78 of these (41.1%) were of potential or actual consequence. We conclude that the performance of senior emergency department staff in non-contrast cranial CT interpretation is no better than moderately good, and a large proportion of misinterpretations are of potential or actual clinical consequence.

Skull fracture as a herald of intracranial abnormality in children with mild head injury: is there a role for skull radiographs?
The aim of the present study is to assess if skull fracture is a useful predictor of intracranial abnormality in children with minor head injury (MHI) and to evaluate the usefulness of skull radiographs. Retrospective review of CT scans and skull X-rays (SXR) of children <14 years of age with blunt head injury and correlation with the Glascow Coma Score definition of MHI (GCS > 12/15 or > 9/11) over a 1-year period was done. Three-hundred and eighty-one patients were included with a mean age of 6 years. ⋯ We demonstrated that omitting CT in MHI could result in missed intracranial abnormalities. All MHI with drainable collections had fractures. Fractures identified on SXR can be added to the clinical indications for CT in MHI and can improve detection of 'silent' drainable collections.

Hiding in the bunker: Challenges for a radiation oncology department operating in the Severe Acute Respiratory Syndrome outbreak.
In February 2003, one woman returned from Hong Kong to Singapore with a previously undescribed atypical pneumonia. Two months later, Singapore is facing its greatest ever threat to its population's health and the country's economy. ⋯ As a radiation oncology department in Singapore, we have faced challenges in keeping staff and patients safe while continuing to provide a service to our patients. In this article, we outline the measures taken to curb SARS in Singapore and discuss the implications for Australasian radiation oncology departments.
