RESUMO
A case of bilateral forearm localization of multiple hereditary osteochondromata and unilateral Kienböck's disease is reported. Ulnar minus variance is frequent in both diseases. Carpal slip is often found in multiple hereditary osteochondromata. In this case, the extremity having both multiple hereditary osteochondromata and Kienböck's disease had no carpal slip. This might have produced an excess load on the lunate, which might have provoked Kienböck's disease.

The authors present a new system for the automatic detection of sleep spindles. The electronic and computer analysis are described and a comparison between automatic and visual analysis, performed by two independent readers, was carried out with the aim of evaluating the reliability of the system. Results are discussed and compared with those of different systems already described.

The study of the REM-process by means of the oculomotor frequencies has shown that it is a stochastic point process. Therefore, the techniques utilized to quantify the time-dependency of this process were used. The structure of occurrence of REM's quantified by transition probability matrixes evidenced a two-state first order semi-Markov process. The oculo-motor configurations of REM-sleep revealed two independent entities, their number and their relative frequencies. This conclusion was used as a working hypothesis for the Spacelab 1 sleep-recording experiment in zero-gravity. The results confirmed the underlying hypothesis.
