To determine the association between mortality and the level of prehospital care in severely injured blunt trauma patients with or without severe head injury.

Level of prehospital care and risk of mortality in patients with and without severe blunt head injury.

Until recently, very little national and international information has existed on the level of computerisation in general practice medicine. This study was undertaken to describe the current state of information technology (IT) systems in general practice medicine in New Zealand.

Aims To investigate the hypothesis that use of antibiotics is related to subsequent development of breast cancer and also to apply this theory to other cancer types. Materials and methods A nested case-control study was conducted, using data linkage between the RNZCGP Research Unit database and the New Zealand Hospital Separation Diagnosis database. Cancer related hospital admissions were identified between 1998 and 2002, and prior antibiotic exposure in these patients was then found. Results A total of 6678 patients were identified with a newly diagnosed cancer in this time period. A slightly increased odds ratio (OR) (95% CI) for breast cancer was seen with penicillin, 1.07 (1.02-1.13). Penicillin was also associated with an increased OR with lung and respiratory cancer, 1.13 (1.06-1.21), and skin neoplasms, 1.05 (1.02-1.08). Significant associations were seen between macrolides and leukaemia, 1.15 (1.01-1.30), lung and respiratory cancers, 1.23 (1.10-1.38) and non-Hodgkin's lymphoma, 1.26 (1.02-1.55). Tetracyclines were significantly associated with non-Hodgkin's lymphoma, 1.12 (1.01-1.24). Cephalosporins only showed a significant association with leukaemia, 1.35 (1.06-1.71), sulphonamides with colorectal cancers, 1.12 (1.01-1.24), and 'other' antibiotic classes with bladder and renal cancers, 1.34 (1.07-1.67). Conclusions It is most likely that antibiotic exposure represents a confounding factor rather than a causation for breast cancer and other cancer types.

The south Asian tsunami on 26 December, 2004, saw Australia deploy civilian teams to an international disaster in large numbers for the first time. The logistics of supporting such teams in both a self sustainability capacity and medical equipment had not previously been planned for or tested. For the first Australian team deployed to Banda Aceh, which arrived on the fourth day after the tsunami, equipment sourced from the New South Wales Fire Brigades Urban Search and Rescue (US&R) cache supplied all food, water, tents, generators and sleeping equipment. The medical equipment was largely sourced from the CareFlight US&R medical cache. There were significant deficits in surgical equipment as the medical cache had not been designed to provide a stand alone surgical capability. This resulted in the need for substantial improvisation by the surgical teams during the deployment. Despite this, the team performed nearly 140 major procedures in austere circumstances and significantly contributed to the early international response to this major humanitarian disaster.
