Previous reports of intracranial neoplasms from Africa have all shown a very low incidence of acoustic schwannomas (neuromas). In this series a group of 11 cerebellopontine angle solid tumours from black Africans were studied. On conventional histological examination only 3 had the features of a schwannoma.

The results of repair of 18 facial nerves were examined by means of a modified House-Brackmann grading system. Six were repaired by end-to-end anastomosis and 12 by nerve graft. The reliability of the simplified House-Brackmann grading system was also assessed, using the kappa statistic to analyze the agreement between pairs of observers who examined the(More)
Three different types of single-piece ventriculoperitoneal shunts with distal slit-valve control (Codman Unishunt, Codman Unishunt with chambers, and Heyer-Schulte one-piece shunt) in their low- and medium-pressure forms were assessed in the laboratory by both static and dynamic tests. A statistical analysis of variance showed large differences in(More)

Twelve subjects had both devices inserted in neighbouring sites. In two patients there were obvious technical problems with the fibre-optic system and the results were therefore excluded from further analysis. In the(More)
