Status of vision following surgical treatment of craniopharyngiomas.

The authors report visual results in a series of 42 patients with craniopharyngiomas. Visual abnormalities were present in 91% of the children and in 83% of the adults. Total removal was achieved in 16 patients with 3 postoperative deaths and subtotal removal in 26 patients with only one postoperative death. Of the 38 survivors, 63% improved, 26% remained the same and 10% worsened. When analyzing the influence of factors such as age, nature and location of the tumour, extent of removal, surgical approach, use of CT scan facilities and duration and degree of the deficit in the 31 survivors with preoperative visual impairment, it became apparent that only the duration and degree of preoperative visual deficit had a significant influence the outcome. The authors discuss also the suggestion that a conservative attitude may be associated with better visual results.

Connections of the cerebellar grains with neuroglial and vascular structures. Interpretation of the grain as a modified neuroglial element.

Using the slightly modified method of Golgi-Valenzuela we studied the cerebellum of 2-week-old dogs. We noted a close anatomical relationship between the cerebellar grains and blood vessels. We found this similar to those of other neuroglial elements. We have described contacts between dendrites of the grains, similar to those of known synaptic junctions. We consider the cerebellar grains as a possible evolutionary form of astrocytes. In this respect, the author would like to interpret them as a possible basis for pathogenetic interpretation of neurological disorders such as ataxia-telangiectasia syndrome, an ontogenic bond between undifferentiated blood elements, astroglia, oligodendroglia and cerebellar grains.
