[Long-term surgical outcomes in congenital malformations of the floor of the auricle].

The authors analyse long-term outcomes of surgical treatment of congenital defects of the floor of the auricle. They came to the conclusion that surgical techniques used in the correction of the defects need some modification. In the presence of a wide, elastic ascending crus of the helix, when creating the anthelix, the crus should be made finer.

[Neurofibrillary changes in the nerve tissue of humans and animals].

Electron microscopy was employed to study neurofibrillary++ alterations in some parts of the brain of man aged 73 and 83 years (physiological ageing) and 36 to 80 years (vascular pathology) as well as in the spinal ganglion of dogs at different times after ischemia. Neurofibrillary++ alterations consisting in hyperplasia of microfilaments and formation of fibrillar bundles were recorded in both cases in nerve and glial cells and in their processes whereas in the human brain, they could be also detected in the intercellular space. Experimentally, filamentous hyperplasia in neurons was the most prevalent form whose intensity was related to the time elapsed after ischemia, attaining maximum in neurons with destructive processes.
