During a 6-year period (1984-89), 31 patients were treated at Rambam Medical Center with penetrating craniocerebral injuries (PCCI) not associated with military action. Eighteen (58%) patients died during their initial hospitalization; only two of them had admission Glasgow Coma Scale (GCS) above five. The admission GCS coupled with the mode of injury (type of missile and motivation of shooting) were valuable for early accurate prognosis assessment. ⋯ The neurological status, CT appearance, as well as the motivation of shooting should be considered in order to assess accurately the possible outcome. Compared with our military series of 113 patients with PCCI, there were more extensive injuries, although the mean period until neurosurgical treatment was the same. Long-term complications connected to dural tears remote from the entrance wound occurred in three of the survivors.

The effects of high velocity missiles are described. A series of cases of craniocerebral tangential gunshot wounds over a 6 year period is presented with unsuspected cerebral contusion shown by CT. ⋯ The short- and long-term sequelae and the extent of cerebral damage belie the innocent appearance of the scalp wound. This influences the management of this unusual type of head injury.

Case Reports
The role of the perforated segment of the ventricular catheter in cerebrospinal fluid leakage into the brain.
Two cases of gross post-operative cerebrospinal fluid (CSF) leakage along an indwelling ventricular catheter are reported. The CSF appeared to leak through the perforations of the ventricular catheter, as well as at the site of penetration of the ventricular wall. A small or slit ventricle with high intraventricular pressure may thus be a predisposing factor for this localized CSF collection.

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)

A bipolar electrode has been designed to assess the possibility of locating accurately the electrode tip position within a nerve pathway prior to its thermal coagulation without having recourse to a wake-up procedure. By electrically stimulating each of the peripheral divisions of the trigeminal nerve and recording the evoked activity pre-ganglionically from the electrode, using an averaging computer, a clear triphasic response is recorded. ⋯ A preliminary series of 12 patients with trigeminal neuralgia requiring operative treatment were assessed in this study. In eight cases a clear response was obtained, in two the signal-to-noise ratio was too small, in one stimulus artefact obscured the response and in one a blood vessel was hit.
