    Notes: Abstract A particular continuous single facility minimax location problem on the surface of a hemisphere is discussed. We assume that all the demand points are equiweighted. An algorithm, based on spherical trigonometry, for finding the minimax point is presented. The minimax point thus obtained is unique and the algorithm is O(n 2) in the worst case.

    Notes: Abstract We reviewed our experience of 25 children with adrenocortical tumours from January 1980 to December 1994. Their ages ranged from 7 months to 15 years; there were 16 girls and 9 boys. Truncal obesity, moon facies, hypertension, and virilisation were the most common clinical features. Establishment of the diagnosis of Cushing's syndrome was accomplished by hormonal and radiological studies. Eighteen patients had adrenocortical carcinomas, but 2 of them refused operation; 7 had adrenocortical adenomas. Twenty-three patients were treated by surgery; 6 with carcinomas are still alive after periods of 6 months to 3 years. The results of treatment of adrenocortical carcinoma have been poor, but the prognosis is excellent for benign lesions.
