A suicidal injury from a livestock stunner ("humane killer") serves to demonstrate the reconstruction possibilities presented by the morphology of the bolt entrance wound and the imprimata. There are differences to common bullet entrance holes with regard to caliber and soot deposits but also with regard to the wound margin features and the characteristics with shots fired at an oblique angle.

The association between skull fracture, intracranial pathology and outcome in pediatric head injury.
We prospectively studied 653 consecutive head-injured children (less than or equal to 14 years old) treated over a 54-month period (1984-88) at the Department of Neurosurgery of the Rambam Medical Center (Haifa, Israel). Demographic and clinical data were collected, the patients were divided into five age groups (birth to 2 years, 169; 3-5 years, 194; 6-9 years, 164; 10-12 years, 77; and 13-14 years, 49), and the information relative to each was then compared. All patients (except three who died on the operating table) underwent computed tomography (CT) scans; 225 (34.6%) had intracranial pathology, e.g. focal mass lesions, diffuse axonal injury, and subarachnoid haemorrhage. ⋯ The mortality was 6.6% (43 patients); of these, 39 (90.7%) had admission Glasgow Coma Scale scores below 8. In our area the annual incidence of neurosurgical hospitalization due to head injury in the pediatric group was 37.6 per 100,000 inhabitants per year. This study substantiates the findings of other series on the effects of prognosis of factors such as associated trauma, admission Glasgow Coma Score, mass lesions with persistent intracranial pressure elevation, or diffuse axonal injury.(ABSTRACT TRUNCATED AT 250 WORDS)

[Effects of Diprivan on cerebral blood flow, intracranial pressure and cerebral metabolism in head injured patients].
The effects of propofol on cerebral blood flow, intracranial pressure (ICP) and cerebral oxygen consumption (CMRO2) were assessed in ten severely head-injured patients undergoing surgery for limb fractures. The patients, aged between 15 and 40 years, were in deep coma, scored 6-7 on the Glasgow coma score. They were mechanically ventilated and sedated with 1 mg.h-1 phenoperidine. ⋯ A radial artery cannula, a 7.5 Fr thermodilution flow-directed pulmonary arterial catheter, a cerebral intraventricular catheter and a catheter in the jugular venous bulb were used for this purpose. Carotid arterial injection of 133Xenon was used to determine regional cerebral blood flow (rCBF). Anaesthetic blood concentrations of propofol (3 to 5 micrograms.ml-1) were associated with a decrease in all the parameters studied: cerebral perfusion pressure, from 82 +/- 14 mmHg to 59 +/- 7 mmHg (p less than 0.001); rCBF, from 35 +/- 6 ml.100 g-1.min-1 to 26 +/- 5 ml.100 g-1.min-1 (p less than 0.01); ICP from 11.3 +/- 2.6 mmHg to 9.2 +/- 2.5 mmHg (p less than 0.001); CMRO2 from 1.63 +/- 0.38 mlO2 +/- 100 g-1.min-1 to 1.18 +/- 0.38 mlO2.100 g-1.min-1 (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Multicenter Study Clinical TrialInitial CT findings in 753 patients with severe head injury. A report from the NIH Traumatic Coma Data Bank.
In this prospective multicenter study, the authors have examined data derived from the initial computerized tomography (CT) scans of 753 patients with severe head injury. When the CT findings were related to abnormal intracranial pressure and to death, the most important characteristics of the scans were: midline shift: compression or obliteration of the mesencephalic cisterns: and the presence of subarachnoid blood. Diffuse hemispheric swelling was also found to be associated with an early episode of either hypoxia or hypotension.

Long-term follow-up review of 31 children with severe closed head trauma.
Thirty-one children aged 3 to 15 years were followed for 5 to 11 years after suffering severe closed head trauma which caused coma for 1 week or more (median duration of coma 3 weeks). One patient remained in a persistent vegetative state until his death 9 years later. The other 30 recovered consciousness and were discharged. ⋯ Social problems were common. The worst outcomes were associated with intracranial bleeding and/or brain contusion seen on computerized tomography (CT) scans at the acute stage; the best were associated with normal CT scans. The degree of residual disability in these children seems no less than that of adults with trauma of similar severity.
