RESUMEN

BACKGROUND: Victoria recently established a new trauma care system following the Consultative Committee's findings on frequent preventable deaths after road crash injury. This study investigates the contribution to neurologic disability of preventable deficiencies in health care in survivors of road crashes occurring from 1998 to 1999. METHODS: The emergency and clinical management of 60 road crash survivors with head Abbreviated Injury Scale score > or = 3 and residual neurologic disability were evaluated by analysis and multidisciplinary discussion of their complete prehospital, hospital, and rehabilitation records. RESULTS: The mean number of potentially preventable errors or inadequacies per patient was 19.2 +/- 7.5, with 10.5 +/- 7.2 contributing to neurologic disability. The mean number contributing to neurologic disability was greatest in the emergency room (3.5 +/- 3.2), followed by the intensive care unit (2.2 +/- 2.7) and the prehospital setting (1.8 +/- 2.0). Eighty-four percent of the deficiencies were management errors/inadequacies and 7% were system inadequacies. Fifty-five percent of deficiencies contributed to neurologic disability. In patients with a systolic blood pressure less than 90 mm Hg with hypovolemia consequent to inadequate resuscitation, the frequency of severe neurologic disability was increased almost twofold (p < 0.05). Deficiencies contributing to neurologic disability were significantly less frequent in university teaching hospitals with neurosurgical units. CONCLUSION: Improvement in neurologic outcomes can be achieved through appropriate triage and increased attention to basic principles of trauma and head injury care.

RESUMEN

Since 1992 the Consultative Committee on Road Traffic Fatalities in Victoria (CCRTF) has examined the medical management of patients who died following motor vehicle accidents. Three hundred and fifty-five fatalities with head injury occurring between 1 July, 1992 and 31 December 1997 were assessed by the CCRTF. They represented 79% of the total 449 fatalities examined by the Committee. Following examination of the complete medical records and multidisciplinary discussion, the Committee considered 237 (67%) of the 355 neurotrauma deaths to be non-preventable, 105 (30%) potentially preventable and 13 (4%) preventable. The present analysis excludes the non-preventable deaths in order to focus on preventable factors. Problems identified in the 118 patients pre-hospital included: no intubation; prolonged scene time; and no intravenous access; in 139 emergency room attendances: inappropriate reception including delay in arrival of a consultant, no neurosurgical consultation, no CT scan of the head, inadequate blood gases and oxygen monitoring, inadequate fluid resuscitation, delayed respiratory resuscitation and delayed dispatch to the operating room; in 111 operating room visits: no ICP monitoring, inadequate fluid administration and inappropriate anaesthetic technique; and in 90 intensive care unit admissions: no ICP monitoring. Overall, 1745 individual problems in the various areas of care were identified, of which 1104 (63%) were judged to have contributed to death. Improved delivery and quality of trauma care could reduce the identified problems in emergency services and clinical management. Basic principles of trauma management remain the most important means of reducing morbidity and death following road trauma. The leadership role of the neurosurgeon in neurotrauma care is emphasised.

RESUMEN

The possible occurrence of fetal abuse in expectant mothers has received little attention in either clinical practice or in research. Five cases with reported fetal abuse are presented. Each case suffered from depression and four of the five women had unplanned pregnancies and had considered a termination of pregnancy. Other possible factors associated with fetal abuse included: denial of the pregnancy, ambivalence towards the pregnancy, previous postpartum depression, and relationship difficulties. Enquiry of possible fetal abuse in pregnant women should be made, particularly if a depressive illness is demonstrated. The relationship between fetal abuse and subsequent child abuse remains unclear.

RESUMEN

A retrospective analysis of 32 patients with posterior circulation aneurysms operated on within three days of subarachnoid haemorrhage is presented. The cases were treated at two Australian neurosurgery units over a five year period (1988-1992), both units having a policy of treating patients of all grades and all ages with early surgery. No patients suffered rebleeding. Five patients developed clinical vasopasm. Twenty-four patients (75%) had a good outcome (Glasgow Outcome Score 1-2), three had a poor outcome (GOS 3), and five died (16%). Of the five deaths, three presented as Hunt and Hess grade V. The results are considered in detail and the literature regarding the timing of surgery for posterior circulation aneurysms is reviewed.

RESUMEN

Gliomas are usually incurable with current treatment regimens. The mainstay of current therapy is surgery and radiotherapy. Adjuvant chemotherapy with nitrosourea-based regimens for high-grade glioma has now been established as a means of improving survival times, although the results are disappointing and the treatment may entail significant morbidity and does not offer the prospect of cure. The role of chemotherapy for low-grade glioma is controversial, and its possible role as a primary therapy aimed at delaying the need for radiotherapy in young children must be better defined. The literature regarding chemotherapy of glioma is reviewed with particular emphasis on recent publications.

RESUMEN

Neurocytoma has only recently been recognized as a distinct pathological entity. Previously a rare tumor, it is now being recognized with increasing frequency. It typically presents in an intraventricular location in young adults. Many neurocytomas were originally diagnosed by light microscopy as oligodendrogliomas. More recently they have been shown to have ultrastructural and immunohistochemical features of neuronal differentiation. This paper presents two cases of intraventricular neurocytomas and reviews the recent literature.

RESUMEN

A 75-year-old man presented with a right cerebellopontine angle tumor 11 months after complete macroscopic resection of a right acoustic neurilemoma. Histological examination of the recurrent tumor showed a malignant spindle-cell neoplasm with positive staining for S-100 protein. The patient had no stigmata of von Recklinghausen's disease. It is proposed that this recurrence represents progression from a benign to a malignant acoustic nerve-sheath tumor, an event that is extremely rare outside the clinicopathological context of neurofibromatosis.
