Diffuse axonal injury (DAI) as defined by detailed microscopic examination was found in 34 of 80 consecutive cases of head trauma surviving for a sufficient length of time to be clinically assessed by the Royal Adelaide Hospital Neurosurgery Unit. The findings indicate that there is a spectrum of axonal injury and that one third of cases of DAI recovered(More)
Tottering (tg) mice inherit a recessive mutation of the calcium channel alpha 1A subunit gene, which encodes the pore-forming protein of P/Q-type voltage-sensitive calcium channels and is predominantly expressed in cerebellar granule and Purkinje neurons. The phenotypic consequences of the tottering mutation include ataxia, polyspike discharges, and an(More)
Gamma-aminobutyric acid (GABA) containing neurons were characterized in human association cortex by a combination of Golgi impregnation and immunohistochemistry. Neurons were Golgi impregnated, gold toned, drawn and then classified on the basis of their dendritic and axonal arborization in layers I-VI. An antiserum to GABA was used to determine which of the(More)
Digital investigation methods are becoming more and more important due to the proliferation of digital crimes and crimes involving digital evidence. Network forensics is a research area that gathers evidence by collecting and analysing network traffic data logs. This analysis can be a difficult process, especially because of the high variability of these(More)
A double-blind trial of phenytoin therapy following craniotomy was performed to test the hypothesis that phenytoin is effective in reducing postoperative epilepsy. A significant reduction in the frequency of epilepsy was observed in the group receiving the active drug up to the 10th postoperative week. Half of the seizures occurred in the first 2 weeks and(More)
In a double-blind trial of phenytoin for the prevention of postoperative epilepsy in craniotomy patients, epilepsy was observed in 7.9% (8/101) of patients treated with phenytoin and in 16.7% (17/102) of those receiving placebo. Therapeutic drug levels were associated with a significant reduction in the frequency of epilepsy. Three-quarters of the fits(More)
The aetiology, mechanisms of haemorrhage and results of treatment of a series of 63 consecutive cases of acute subdural haematoma are presented. Forty-six cases were due to trauma (46% mortality) and 17 cases were non-traumatic (41% mortality). Only 15 patients overall (24%) made a good recovery. The various mechanisms of venous and arterial bleeding(More)
Two cases of spinal epidural abscess following prolonged epidural anaesthesia are presented. The clinical features included fever, malaise, and signs of nerve root compression; backache was not marked. Prompt surgical drainage and appropriate antibiotics are required to avoid the costly sequelae of bladder and leg paralysis from spinal cord compression.(More)
