The clinical features, treatment, and outcome were reviewed for 48 patients with a haematoma and 71 patients with an infarct in the posterior fossa in order to develop a rational plan of management. Clinical features alone were insufficient to make a diagnosis in about half of the series. Patients with a haematoma were referred more quickly to the(More)
Cortical contusions are one of the most common characteristics in head injury and are regarded by many as the hallmark of significant injury. No experimental study has clarified the roles of mechanical forces, haemorrhage and ischaemia in the process of progressive acute brain damage and later neurobehavioural dysfunction. We have devised a new, simple(More)
This is a retrospective review of the clinical presentation, diagnosis and management of 62 patients with histologically proven intradural conus and cauda equina tumours. In the majority of cases the clinical presentation clearly suggests the need for further investigation. One fifth of the patients had small intramedullary tumours, which presented(More)
The authors have devised a simple reproducible rodent model of focal cortical injury that uses a mechanical suction force applied through intact dura. The time course and pattern of changes in neurons, glia, and microvasculature were investigated using this model. Early traumatic disruption of the blood-brain barrier and hemorrhage do not occur in this(More)
In a new, reproducible model of rodent focal cortical injury, we have shown that in the absence of early traumatic disruption of the microvasculature and subsequent hemorrhage, delayed perivascular protein leakage and polymorphonuclear leukocyte infiltration of the injured cortex occur. In this study we employed a sensitive quantitative autoradiographic(More)
We have retrospectively reviewed 23 conscious patients, in whom a CT scan diagnosis of acute subdural haematoma was made, and in whom craniotomy for evacuation was not initially performed. These highly selected patients represent 3% of 837 patients with acute subdural haematoma, presenting over a five year, eight month period to the Institute of(More)
The pancreatic teratoma is a congenital tumor which results from abnormal embryonic development of totipotent cells. The preoperative diagnosis is challenging. We report, to our knowledge, the 26th case in a 64-year-old man in whom the diagnosis was made preoperatively on imaging.
Isolated pancreatic injury is uncommon and the management is challenging. Presentation is mostly delayed in such cases. We report a case of 26-year-old male, who was referred to our centre due to blunt abdominal trauma of 48 h duration with pain abdomen and vomiting. He was haemodynamically stable and was subjected to endoscopy after few hours of admission,(More)
