title: Head trauma in northern Israel: incidence and types.
abstract: A descriptive epidemiological study of neurotraumatology was undertaken over a 4.5-year period at a regional hospital with a referral base of 1,200,000 residents served by a single neurosurgical department. Neurosurgical evaluations and treatments were given to 1,370 patients in this period. The data base consists of demographic, clinical and radiological features at the time of admission, as well as the hospital course through discharge. The crude incidence rate was 25.2 +/- 3.1 cases per 100,000 person-years (similar to that of three neurosurgical units in Scotland). Age adjustment showed almost twice this rate at the two extremes of age and a smaller elevation in early adulthood. The crude incidence was 36.9 for males and 13.4 for females (p less than 0.01). Age-specific incidence rates in Jews compared to other ethnic groups were reported. Falls had an incidence of 12.8 (51%), road accidents 9.0 (35.7%) and assaults 2.3 (9%) per 100,000 person-years. Other causes were accidents during work or sport and suicide. The rate of brain pathology as revealed by computerized tomography steadily increased from 19% in childhood to 71% in the elderly with a mean of 41.8%. A similar increasing trend with age was found in the rate of intracranial mass lesions (mean 28.3%), impaired consciousness (30.4%) and mortality (13%).
