[Health and military service. The loss of conscripts because of various medical grounds].

250 conscripts who met for basic training in 1976 were followed to 1984. All the 250 conscripts were among those found fit for active service (fit for combat) at the first medical examination in 1975. In 1984 only 50% of the 250 were still considered fit for active service. During the period of 12 months' basic training and the seven years that followed a considerable reduction of the number of fit for active service had taken place on medical grounds. Based on these findings we estimate the expected reduction of conscripts fit for active service in future cohorts. The reduction on medical grounds, combined with the effect of declining birth rates, leads to a marked decrease in the number of fit conscripts who have completed basic training. The number of fit conscripts will probably be smaller than estimated need of the Services for fit men.

Head injuries during one year in a central hospital in Norway: a prospective study. Epidemiologic features.

Annual age-adjusted incidence rate of head injuries in Akershus County in 1974 was estimated to be 236/100,000, 307/100,000 for males and 164/100,000 for females. The highest incidence rate occurred in males in the age group 10-19 years (489/100,000) and the lowest among females in the age group 30-39 (68/100,000). In all age groups, the incidence rate was higher in males than females. This prospective study included 488 patients, of whom 88.9% had minor head injuries and 11.1% severe head injuries. 16 patients (3.3%) died due to their head trauma. Skull fracture was detected in 10.4% of the patients who survived the first 24 h, and 2.5% had operations. The mean hospital stay was 8.8 days, 10.2 days for the patients injured in traffic accidents and 7.0 days for the others. Besides having a higher incidence rate of head injuries, males suffered severe head injuries more often and their death rate was higher than head-injured females.

Long-term prognosis of patients with central cerebral ventricular enlargement. A fifth follow-up study of 100 patients with a 3rd ventricle measuring 12 mm or more in width.

One hundred patients with a 3rd ventricle width of 12 mm or more were examined for the fifth time in 1976 after an average observation period of 20.8 years. On first admission, a predominant aetiological factor was found in 27 cases. Two patients had air-encephalogrophical findings indicating normal pressure hydrocephalus. One of these had a shunt operation, however, without improvement. Seventy-one patients had died, 7 patients were in need of care and supervision, 11 patients were unable to work, the remaining 11 were able to work to some extent. The group studied had a significantly increased mortality rate. The causes of death were divided into three groups: 1. Probably related to the underlying brain disorder; 2. Related to those in an average Norwegian population; and 3. Minor disorder usually not leading to death. The following factors indicated a poor long-term prognosis: 1. Serious associated disease; 2. A relatively high age; 3. Associated cardiovascular disease; 4. Marked degree of ventricular enlargement; 5. Marked enlargement of the temporal horns; 6. Many and/or marked neurological signs; and 7. Prognosis intellectual deterioration.
