BACKGROUND It has been suggested that graft dilatation following repair of abdominal aortic aneurysm (AAA) is associated with complications such as anastomotic aneurysm and graft rupture. The purpose of the present study was to document the degree of dilatation observed in grafts after aneurysm repair and to correlate this with any graft-related(More)
A common cause of pathological nystagmus is malfunction of the mechanism by which the brain integrates eye velocity signals to produce eye position commands. For horizontal gaze, neurons in the nucleus prepositus hypoglossi-medial vestibular nucleus region (NPH-MVN) play a vital role in this neural integrator function. We studied the effects on gaze(More)
BACKGROUND Few studies of intimate partner violence (IPV) interventions have been conducted in primary care settings. Based on recommendations, we implemented a multifaceted IPV intervention that included a sticker placed in medical charts listing screening questions, routine IPV screening by nursing staff, clinician follow-up for women screening positive,(More)
A novel endovascular treatment involving cyanoacrylate injection followed by endovascular stent placement is described in the setting of life-threatening acute exsanguination through a primary aortoenteric fistula. In a patient in unstable condition, N-butyl 2-cyanoacrylate was injected into the fistula tract. Rapid polymerization first provided hemostasis(More)
OBJECTIVE Cricoid pressure, applied during rapid sequence induction of anaesthesia, should be performed only by trained staff. Recommended training intervals vary from weekly to every 3 months, but this is unrealistic in day-to-day practice. Performance, when assessed, is often shown to be unacceptable before training. Unfortunately, most training aids are(More)
BACKGROUND Radiofrequency (RF) ablation utilizing direct endocardial visualization (DEV) requires a "virtual electrode" to deliver RF energy while preserving visualization. This study aimed to: (1) examine the virtual electrode RF ablation efficacy; (2) determine the optimal power and duration settings; and (3) evaluate the utility of virtual electrode(More)
BACKGROUND As Australia's population ages, the number of elderly patients presenting for surgery of abdominal aortic aneurysms (AAA), both elective and ruptured, will increase. The aim of the present study was to compare the costs of treatment of patients with AAA, under and over the age of 80, in the elective and emergency settings in a hospital with a(More)
BACKGROUND The appropriate management of patients who are older than 80 years of age and who present with an abdominal aortic aneurysm (AAA) remains controversial. While it appears that elective repair can be performed safely, appropriate management of these patients in the emergency situation is unclear. The purpose of the present study was to examine the(More)
OBJECTIVES The aim of this study was to assess the feasibility of using electrode temperature, impedance, and power to predict and thereby potentially prevent steam pops during cooled radiofrequency (RF) ablation. BACKGROUND When myocardial temperature reaches 100 degrees C during RF catheter ablation, steam explosions are seen. Saline-cooled RF ablation(More)
Several epidemiological studies have shown an association between the season in which certain cancers are diagnosed and survival, with diagnosis in summer and autumn being associated with better survival. In this study, we have added resolution to the analysis of seasonality in cancer survival by considering mortality within several nonoverlapping time(More)
