Development of a productive research culture in emergency medicine: Report of the outcomes of a research forum.

In recent years, the Australasian College for Emergency Medicine (ACEM) has increasingly focused on the need for high-quality research in emergency medicine (EM). One important initiative was the establishment of the ACEM Foundation, which among other responsibilities, is required to support clinical research through the provision of research funding and other measures. In February 2015, the Foundation held a Research Forum that was attended by the leading EM researchers from Australasia. The Forum aimed to determine how a productive research culture could be developed within the ACEM. Nine key objectives were determined including that research should be a core business of the ACEM and a core activity of the EM workforce, and that EM research should be sustainable and adequately supported. This report describes the background and conduct of the Forum, its recommendations and the way in which they could be implemented.

The rational clinician in a pandemic setting.

Pandemic (H1N1) 2009 influenza has generated many controversies in Australia around case definitions, laboratory diagnosis, case management, medical logistics and travel restrictions. Our experience as clinical advisers in the Victorian Department of Human Services Emergency Operations Centre suggests the following: Case definitions may change frequently, and will tend to become more clinically specific over time. Early in a pandemic, laboratory diagnosis plays a critical role in case finding and pathogen identification. Later in the pandemic, standardised case management applied to well crafted case definitions should reduce reliance on the diagnostic laboratory in clinical management. The diagnostic laboratory will remain critical to monitoring disease surveillance, pathogen virulence, and drug susceptibility. Medical logistics will continue to challenge pandemic managers as the health sector struggles to do the most good for the greatest number of people. Travel restrictions remain scientifically controversial public health recommendations. Issues of scalability (escalation and de-escalation of the response) relating to virus lethality need to be resolved in current pandemic planning.

SF-36 outcomes and fusion rates after multilevel laminectomies and 1 and 2-level instrumented posterolateral fusions using lamina autograft and demineralized bone matrix.

Short-Form 36 (SF-36) outcomes and fusion rates were assessed after multilevel laminectomies and 1 (95 patients) or 2-level (45 patients) instrumented fusions. The posterolateral fusion mass consisted of lamina autograft and demineralized bone matrix (Osteofil/ICM: Sofamor Danek, Memphis, TN) in a 50:50 mix. SF-36 questionnaires were administered preoperatively and 3, 6, and 12 months postoperatively. Two independent neuroradiologists (blinded to study design) separately documented fusion on both dynamic x-rays and two-dimensional-computed tomography (2D-CT) studies performed 3, 6, and up to 12 months postoperatively until arthrodesis was demonstrated. Patients were followed an average of 3 years in both fusion series (minimum of 1.5 y). One-year postoperatively, comparably improved outcomes were observed for both groups on 6 of 8 Health Scales of the SF-36. 2D-CT studies documented 1-level fusion an average of 5.2 months (Standard Deviation 1.8) postoperatively in 88 (92.6%) of 95 cases, whereas dynamic x-rays confirmed fusion in 93 (98%) patients. For 2 patients undergoing 1-level fusions, both 2D-CT and dynamic x-ray documented pseudarthrosis/instability; both patients required secondary surgery an average of 8 months postoperatively. 2D-CT documented 2-level fusion an average of 6.1 months (Standard Deviation 1.9) postoperatively in 41 of 45 (91.2%) patients, whereas dynamic x-rays confirmed fusion in 43 (96%) patients. For 2 patients undergoing 2-level fusions, both 2D-CT and dynamic x-rays documented pseudarthrosis/instability; both patients required secondary fusion an average of 10 months postoperatively. High fusion rates and adequate outcomes were observed after multilevel laminectomies and 1 and 2-level instrumented posterolateral fusions performed using lamina autograft and demineralized bone matrix: Osteofil/ICM.

Short Form-36 outcomes following focal 1- and 2-level cervical laminectomy with multilevel instrumented fusion.

BACKGROUND: Multilevel laminectomy with instrumented fusion addresses diffuse dorsal cord compression with an adequately preserved cervical lordosis. However, for patients with only 1 to 2 laminar impingement, more "focal" laminectomy and fusion may suffice, the shortened laminectomy allowing for a more simple spinous process fusion skipping the 1 or 2 lamina that have been removed. METHODS: Fourteen patients presented with severe spastic myeloradiculopathy (Nurick grade IV) attributed to magnetic resonance imaging- and CT-documented 1- to 2-level laminar compression, stenosis, and ossification of the yellow ligament. Magnetic resonance images also revealed 1- to 2-level hyperintense signals within the cord at the levels of maximal compromise. Surgical procedures included 1- to 2-level laminectomies and average 6.4-level posterior fusions. Dynamic x-ray/CT studies, which were obtained 3, 6, and up to 12 months postoperatively, followed progression toward fusion. Outcomes were assessed using Nurick grades (0-V) and SF-36 questionnaires assessed preoperatively and up to 12 months postoperatively. RESULTS: Patients improved on all 8 SF-36 Health Scales within the first postoperative year. Maximal improvement was observed on 5 Health Scales within the first 6 postoperative months (physical function, mental health, vitality, general health, role physical). The preoperative average Nurick grade (3.8) improved postoperatively (0.7 at 6 months, 0.5 at 1 year). Dynamic x-ray and CT studies documented fusion for all 14 patients by the sixth postoperative month. CONCLUSIONS: One- and two-level cervical laminectomies with multilevel-instrumented fusion effectively decompressed "focal" cord compression, whereas fusion maintained the cervical lordotic curvature and provided stability to avert future disease progression.

A traumatic central cord syndrome occurring after adequate decompression for cervical spondylosis: biomechanics of injury: case report.

STUDY DESIGN: Case report with review of the literature. OBJECTIVES: To present the first case of a central cord syndrome occurring after adequate decompression, and review the mechanics of the cervical spinal cord injury and postoperative biomechanical and anatomic changes occurring after cervical decompressive laminectomy. SUMMARY OF BACKGROUND DATA: Cervical spondylosis is a common pathoanatomic occurrence in the elderly population and is thought to be one of the primary causes for a central cord syndrome. Decompressive laminectomy with or without fusion has been a primary treatment for spondylotic disease and is thought to be protective against further injury. To our knowledge, there are no cases of a central cord syndrome occurring after adequate decompression reported in the literature. METHODS: Case study with extensive review of the literature. RESULTS: The patient underwent C3-C7 cervical laminectomy without complications. After surgery, the patient's spasticity and gait difficulties improved. She was discharged to inpatient rehabilitation for further treatment of upper extremity weakness. The patient fell in the rehabilitation center, with a central cord syndrome despite adequate decompression of her spinal canal. The patient was treated conservatively for the central cord and had minimal improvement. CONCLUSIONS: Decompressive laminectomy provides an immediate decompressive effect on the spinal cord as seen by the dorsal migration of the cord, however, the biomechanics of the cervical spine after decompressive laminectomy remain uncertain. This case supports the ongoing research and need for more intensive research on postoperative cervical spine biomechanics, including decompressive laminectomies, decompressive laminectomy and fusion, and laminoplasty.

Long distance road transport of a patient with Wegener's Granulomatosis and respiratory failure using extracorporeal membrane oxygenation.

Wegener's Granulomatosis is a necrotizing vasculitis that in its most severe form can cause respiratory failure, renal failure and subglottic stenosis requiring surgical airway access. We describe the use of portable extracorporeal membrane oxygenation and the long distance road transport of a patient with Wegener's Granulomatosis who developed respiratory failure that was refractory to conventional mechanical ventilation. We have demonstrated the effective use of portable extracorporeal membrane oxygenation for stabilization and safe acute interhospital transfer over a long distance by road ambulance to a tertiary centre for further management.
