An apparent increase in young people dying suddenly from acute asthma has been noted in the past 2 years in Auckland. 22 fatal cases were reviewed. Prescribing habits for asthma therapy have been changing in New Zealand, with a considerable increase in the use of oral theophylline drugs, particularly sustained-release preparations, which in many patients(More)
OBJECT The goal of this study was to compare the freehand technique of catheter placement using external landmarks with the technique of using the Ghajar Guide for this procedure. The placement of a ventricular catheter can be a lifesaving procedure, and it is commonly performed by all neurosurgeons. Various methods have been described to cannulate the(More)
OBJECTIVE The Woven Endobridge (WEB) device has been in clinical use for the treatment of brain aneurysms for the past 4 years. Observational studies to assess clinical outcome and related complications have been published. Clear evidence is required to better understand the safety profile of the WEB device. The authors here present a multicenter series(More)
BACKGROUND Liquid embolic agents are the preferred embolic material in endovascular treatment of pial and brain arteriovenous malformations and dural arteriovenous fistulas (DAVFs). There is little choice available in interventional neuroradiology practice other than two of the most commonly used liquid embolic agents-n-butyl cyanoacrylate and the Onyx(More)
i Acknowledgments The synthesis of thought presented in this example has been influenced greatly by the concepts of wildlife habitat management promoted in Oregon by Jack Ward Thomas, Chris Maser, and Ralph Anderson. Their practical ideas about wildlife habitat in managed forests and range-lands were adapted for this management architecture and they are(More)
We report the case of a 58-year old man who presented with a 4 cm right acoustic neuroma. He underwent a translabyrinthine resection. Two years later he presented with multiple strokes and progressive generalised deterioration. A cerebral angiogram demonstrated an extensive right side cerebellar dural arteriovenous fistula with retrograde flow causing(More)
National guidelines exist for the investigation and early management of head injury. Alcohol-related head injury is relatively common in clinical practice, and intoxicated patients can be difficult to fit into guidelines for imaging. A sequential retrospective study compared imaging findings of alcohol-related injuries to sober control cases. We demonstrate(More)
We report a case of dangerous combustion of Tantalum/Onyx embolic agent when exposed to mono-polar diathermy during subsequent surgical resection of a partially embolised arteriovenous malformation. Surgeons should be aware that previous embolisation of a vascular malformation may make use of diathermy problematic if subsequent surgical management is(More)
A case of atlanto-occipital dislocation with incomplete pondomedullary brainstem tear is reported; it resulted from a high-speed motorboat accident. The 43 year old man exhibited a locked-in syndrome; the diagnosis was made with MRI and verified by autopsy. With modern methods of life support, prolonged survival after such injuries is unfortunately(More)
