    Notizen: Summary Two cases of spontaneous ventriculo-aerocele are described. Both patients were eighteen years old and had previously been treated for obstructive hydrocephalus by Torkildsen's bypass, eleven and thirteen years before. Findings relating to the aetiology are described as are some of the problems of treatment.

    Notizen: We have examined the oxidation states and local atomic structures of Ni, Fe, and Co in LixNi0.7Fe0.15Co0.15O2 as a function of Li content during the first charge in a Li//LixNi0.7Fe0.15Co0.15O2 nonaqueous cell. We show that the composition of the material in the pristine state is more accurately described by Li0.95Ni(II)0.09Ni(III)0.66Fe(III)0.15Co(III)0.15O2. Half of the Ni(II) resides in Li-vacant sites. Both Fe and Co substitute for Ni within the NiO2 slabs with no significant amounts of Fe or Co that can be attributed to Li-vacant sites. The local structure parameters are consistent with oxidation states observed on the basis of the XANES data. The Ni K-edge energy continuously shifts to a higher energy with decrease in Li content due to oxidation of Ni(II) to Ni(III) and Ni(III) to Ni(IV). After the complete oxidation of Ni(III) to Ni(IV), the Fe K-edge energy begins to increase with further decrease in Li content indicating the oxidation of Fe(III) to Fe(IV). The Co K-edge energy at half-height, on the other hand, is unchanged during the whole range of Li deintercalation indicating that no significant change in the oxidation state of Co occurs upon the complete removal of Li.

    Notizen: Abstract Five children are presented with complications related to migration of peritoneal shunt tubes. Anchoring the distal end of the peritoneal tube to the peritoneum was found to be a satisfactory answer to the problem in 13 children. This simple method does not add much to the operation time and has prevented shunt-tube migration in the group studied.
