Experience with spinal injuries in New South Wales.

Two hundred and two patients with acute and severe spinal injuries were treated in various hospitals in New South Wales during 1977 and 1978. Of these, 132 (65%) were cervical, 60 (30%) thoracic, eight (4%) lumbar and two were inadequately recorded. A major concurrent injury to the head was present in every third patient, to the chest in every fourth patient, and to the limbs in every fifth patient. The outcomes of patients reported in this series make it one of the worst in the literature. Sixty-nine (34%) patients died in hospital; of the 133 survivors, only 22 (11%) have resumed work, the remainder being partially or totally disabled. It is estimated that another 302 patients died before arrival in hospital. In country areas, the time lags between accident and ambulance notification, and between notification and arrival at hospital, were uncertain in many cases, but periods in excess of 2 hours were recorded in 28 (14%). One-man ambulances or private vehicles were used in at least 43 cases (21%). After admission, 139 patients were transferred to other hospitals for definitive treatment, arriving after an average time of 22 h (median time 9 h); for such patients, the original hospital presumably served as a first aid station. A case control study suggests that preventable delay in transport, inappropriate treatment, and failure to correct shock may have been causative factors in 16 deaths in this series. Reduction of the time lag between accident and institution of definitive treatment will save lives, and may avoid some crippling neurological deficits.(ABSTRACT TRUNCATED AT 250 WORDS)

Experience with chronic subdural haematomas in New South Wales.

This study considered 135 cases of chronic subdural haematoma following head injury in 1977 and 1978. The majority were in the older age group and more often males. Falls were the commonest cause. Among intracranial haematomas they carry a much better prognosis. However, there was a mortality rate of 9% and delay in diagnosis was the most likely preventable factor contributing to this. Accordingly the possibility of this complication after head injury should be known to those concerned in the later hospital treatment and follow-up management especially of older patients and alcoholics. When the diagnosis has been made, the preferred surgical method of treatment is drainage through burrholes. Follow-up CT scanning should be arranged usually about 8 weeks afterwards unless there are clinical indications for an earlier examination.

Progesterone and oestrogen receptors in meningiomas: biochemical and clinicopathological considerations.

Specific progesterone and oestrogen receptor proteins were evaluated by a dextran coated charcoal assay and Scatchard plot analysis in 20 intracranial meningiomas. Eleven tumours (55%) were progesterone receptor (PR) positive (mean 108 fmol/mg cytosol protein), whilst all were oestrogen receptor (ER) negative (ER less than 10 fmol/mg cytosol protein). There were no trends to suggest a relationship between epidemiological data (patient age, sex and reproductive status in females) or meningioma location and size and the receptor status of the tumour. However, of the seven meningiomas that were histologically atypical, invasive or clinically recurred within 18 months, six were PR negative (PR less than 10 fmol/mg cytosol protein). These results confirm that a large proportion of intracranial meningiomas contain significant amounts of specific PR protein and suggest that PR negative meningiomas are biologically more aggressive than PR positive meningiomas. They are also consistent with the hypotheses that PR proteins are not modulated by oestrogens acting through oestrogen receptors and that there are cytokinetic differences between sex hormone receptor proteins in meningioma and breast carcinoma. The full biochemical, cytological and clinical implication of these preliminary findings will, however, require further evaluation because of the unpredictable long-term behaviour of intracranial meningiomas.

Trauma to the central and peripheral nervous systems. Part II: A statistical profile of surgical treatment New South Wales 1977.

The epidemiological aspects of the mortality, morbidity and the costs of neurotrauma in New South Wales 1977 were outlined in Part I of this report. Part II outlines the profile of surgical work in this field in New South Wales in 1977. In all, 21,973 patients were admitted to New South Wales Hospitals in 1977 for neurotraumatic conditions (85% with head, 13% with spinal and 2% with peripheral nerve injuries); and 1,513 patients required surgery (49% with head, 22% with spinal and 29% with peripheral nerve injuries). The profile of surgery for disc disease is outlined. The participation of neurosurgeons in the management of neurotrauma is assessed.

Trauma to the central and peripheral nervous systems: Part I: an overview of mortality, morbidity and costs; N.S.W. 1977.

An epidemiological study of neurotrauma in New South Wales, South Australia and the Australian Capital Territory, 1977, was initiated and sponsored by the Neurosurgical Society of Australasia, conducted by its Trauma Subcommittee in collaboration with the Division of Health Services Research, Health Commission of New South Wales, funded by the Australian Brain Foundation and the Commonwealth Department of Health and supported by the Health Commissions of New South Wales and South Australia. The following communication is structured so as to present the essential findings on mortality, morbidity and costs in New South Wales in 1977 in the first part and the more specific statistical profile of surgical treatment in New South Wales, 1977, in a separate, second part. The most revealing data found by this research is that cranio-cerebral and spinal injury was the leading cause of death up to the age of 44 in New South Wales (and South Australia) and up to the age of 49 in the male population and in the country regions. It accounted for 45% of all deaths to those aged 15 to 24. Cranio-cerebral and spinal injury caused 71% of all deaths on the roads. Sixty-four per cent of those dying in road accidents never reached hospital. The figures for mortality and morbidity in the country regions were significantly worse than those in the metropolitan regions. The most important causes were identified and recommendations aimed at reducing this record were formulated.

Planning for better standards in the care of the neurological sequelae of trauma.

Injuries of the nervous system are common, and cause many deaths and much permanent disability. They inflict an enormous financial burden on the national economy; in Australia, adequate data are at present lacking, but a simple extrapolation from Canadian statistic suggests an estimate of more than $500,000,000 annually for the injuries resulting from road traffic accidents alone; if other causes of injury are included, the figure may reach one billion dollars. The neurosurgeon is specifically trained to undertake the management of all forms of neurological trauma; however, in Australia, and in many other countries, only a small minority of such injuries receive neurosurgical care. This is chiefly because the number of neurosurgeons at present available is small in relation to the tasks. Many cases must therefore be in the care of general or orthopaedic surgeons, especially in country centres, and it is important that these surgeons should have some basic neurosurgical training. The Neurosurgical Society of Australasia wishes to formulate a programme to ensure that opportunities for such training are available throughout Australia. This programme should also embody a national plan for research into the treatment and prevention of neurological trauma.

Sport: assessing the risk.

Studies on the incidence of sports injuries are an integral part of sports medicine. A survey of three sports medicine journals showed a paucity of information in this area. In view of the need for well designed studies, a series of guidelines for studies is presented.
