Advances in neurotrauma in Australia 1970-2000.

The management of neurotrauma in Australia has been one of the significant public health triumphs during the last 30 years of the 20th century. State and national government agencies act in a coordinated fashion to collect data and to promote research or how to manage neurotrauma patients. Between 1970 and 1995, fatalities from road accidents decreased by 47%. Hospital admissions have decreased by 40% despite a 40% increase in the population and a 120% increase in registered vehicles. Fatalities per 10,000 registered vehicles were 8.05% in 1970 and they fell to 1.84% per vehicles in 1995, while fatalities per 10,000 population were 3 in 1970 falling to 1.11 in 1995. Hospitalization from road crashes decreased 23% between March 1988 and March 1997. Public education has steadily improved, backed by the state public health sources. A uniform code of road safety laws has been adopted, backed by legislation and legal penalties and increasing police enforcement. Clinical care of patients has improved as a result of faster communications, tele-medicine, trauma systems, the CT scanner, intensive care units, and improved monitoring. Patient rehabilitation and counseling are now carried out at units accredited by the Australian Council on Health Care Standards.

Defining acute mild head injury in adults: a proposal based on prognostic factors, diagnosis, and management.

The lack of a common, widely acceptable criterion for the definition of trivial, minor, or mild head injury has led to confusion and difficulty in comparing findings in published series. This review proposes that acute head-injured patients previously described as minor, mild, or trivial are defined as "mild head injury," and that further groups are recognized and classified as "low-risk mild head injury," "medium risk mild head injury," or "high-risk mild head injury." Low-risk mild injury patients are those with a Glasgow Coma Score (GCS) of 15 and without a history of loss of consciousness, amnesia, vomiting, or diffuse headache. The risk of intracranial hematoma requiring surgical evacuation is definitively less than 0.1:100. These patients can be sent home with written recommendations. Medium risk mild injury patients have a GCS of 15 and one or more of the following symptoms: loss of consciousness, amnesia, vomiting, or diffuse headache. The risk of intracranial hematoma requiring surgical evacuation is in the range of 1-3:100. Where there is one computed tomography (CT) scanner available in an area for 100,000 people or less, a CT scan should be obtained for such patients. If CT scanning is not so readily available, adults should have a skull x-ray and, if this shows a fracture, should be moved to the "high-risk" category and undergo CT scanning. High-risk mild head injury patients are those with an admission GCS of 14 or 15, with a skull fracture and/or neurological deficits. The risk of intracranial hematoma requiring surgical evacuation is in the range 6-10:100. If a CT scan is available for 500,000 people or less, this examination must be obtained. Patients with one of the following risk factors--coagulopathy, drug or alcohol consumption, previous neurosurgical procedures, pretrauma epilepsy, or age over 60 years--are included in the high-risk group independent of the clinical presentation.

The management of acute neurotrauma in rural and remote locations: A set of guidelines for the care of head and spinal injuries.

The Neurosurgical Society of Australasia through its Trauma Committee has a long involvement in the problem of neurotrauma. The management of acute neurotrauma in rural and remote locations is of particular interest and is part of a general policy which includes education, prevention, organization of an integrated neurotrauma system and support for the Early Management of Severe Trauma (EMST) programme instituted by the Royal Australasian College of Surgeons. The management of acute neurotrauma requires a consultative approach especially in the multiple injured patient and where transfer or retrieval is necessary. As acute neurotrauma may present to general practitioners, rural surgeons or emergency departments in country hospitals, a set of guidelines has been developed to assist in the early management of acute neurotrauma. These guidelines have been previously published by the Neurosurgical Society of Australasia and the Royal Australasian College of Surgeons. They have been extensively used since 1992 by rural health and distance education groups, Royal Flying Doctor Service Emergency Management of Severe Trauma Course of the Royal Australasian College of Surgeons and by overseas education programs for neurotrauma care. This revision updates the guidelines and makes them accessible through the Journal. Reprints are available for practitioners in rural and remote settings, trauma course participants and others.

Cerebral metastatic melanoma presenting as spastic paraparesis.

A case of bilateral deposits from melanoma in the posterior frontal parasagittal region of the brain is recorded. A mechanism to explain the mode of spread is suggested. C.T. head scanning in patients with disseminated malignancy should be considered prior to invasive investigations or major surgical procedures.
