We prospectively and retrospectively reviewed a series of 780 patients who presented to the University of Southern California/Los Angeles County Medical Center with a diagnosis of gunshot wound to the brain during an 8-year period. Of these, 105 were children ranging in age from 6 months to 17 years. Injuries were gang related in 76 (72%) children and adolescents. ⋯ The Department of Neurological Surgery is becoming directly involved in providing information to children at the junior high school level regarding gang activity and brain and spinal cord injury. In conjunction with the Community Youth Gang Services Organization and Think First Organization, we are attempting to integrate prevention through education and community mobilization. This is a plan aimed at informing and recovering the youth affected by gangs.

Comparative Study
Intracranial pressure monitoring in children: comparison of external ventricular device with the fiberoptic system.
Several intracranial pressure monitoring devices have been developed in the past several years. We have recently adopted the Camino fiberoptic device that permits subdural, intraparenchymal, and intraventricular monitoring. In this report we compare experiences in monitoring a group of pediatric patients with severe craniocerebral trauma and coma, grouped according to severity of Glasgow Coma Scale score. ⋯ The study demonstrated that the fiberoptic device and the ventricular catheter have the same accuracy and reliability. The fiberoptic method correlates very closely with the ventriculostomy method, but the pressure values are always 3 +/- 2 mmHg lower than those obtained with the conventional pressure transducer system, especially in more critically ill patients. This new technique is also easier to implant, safer to use, has minimal drift, and is minimally invasive, which particularly speaks for its use in pediatric patients.

The camino ventricular bolt system has been used to monitor intracranial pressure in patients after severe head injury. The correlation between the ventricular pressure measured with the Camino device and an external transducer showed that the Camino accurately measured intracranial pressure over a wide range, but that it read an average of 1.15 mm Hg higher than that obtained by the external transducer. The technique has the advantage over a remote transducer because it is sited within the ventricle. This may be of value in wave-form analysis.

Comparative Study99mTc-HMPAO SPECT of the brain in mild to moderate traumatic brain injury patients: compared with CT--a prospective study.
Single photon emission computed tomography (SPECT) with Technetium-99m hexamethyl propylenamine oxime (Tc-99m-HMPAO) was used in 20 patients with mild to moderate traumatic brain injury (TBI) to evaluate the effects of brain trauma on regional cerebral blood flow (rCBF). SPECT scan was compared with CT scan in 16 patients. SPECT showed intraparenchymal differences in rCBF more often than lesions diagnosed with CT scans (87.5% vs. 37.5%). ⋯ All these patients with fractures had normal brain on CT scans. Conversely, extra-axial lesions and fractures evident on CT did not visualize on SPECT, but SPECT demonstrated associated changes in rCBF. Although there is still lack of clinical and pathological correlation, SPECT appears to be a promising method for a more sensitive evaluation of axial lesions in patients with mild to moderate TBI.
