[Syndromology and differential treatment of secondary cochleovestibulitis in patients with early clinical forms of cerebral circulatory insufficiency].

Altogether 136 patients with cochleovestibulitis and early clinical forms of cerebral circulation insufficiency were examined. Two types of syndrome were identified that were associated with the pathogenetic development: vascular and metabolic. Different diagnostic criteria and therapeutic approaches as applied to each type of syndrome were developed.

[How useful is the intersaccadic interval analysis of vestibular nystagmus for clinical diagnostic (author's transl)].

The intersaccadic interval analysis of vestibular nystagmus was proposed by Cheng et al. in 1974. This method gives a statistical and sequential description of intersaccadic intervals. Until now there were no reports concerning the clinical diagnostic relevance of this method in vestibular disturbancies. Therefore, we checked 8 normal probands and 7 patients (3 peripheral, 3 central vestibular lesions, one congenital nystagmus). Compared to common nystagmus parameters like maximum speed of slow phase or minimum frequency normal probands showed a relatively high variability, as well as the patients - excluding congenital nystagmus. The maximum of intersaccadic intervals of the latter was very marked between 0,9 and 1,0 seconds. In the other cases the normally monomodal distributed maxima were between 0,2 and 0,6 sec. A multimodal distribution, as described by Cheng et al. in 1974, were to be found very seldomly. The comparison of intersaccadic interval analysis with the common nystagmus parameters showed, that in clinical diagnostic this method should not be too necessary. However, regarding scientific research - including mathematical models of vestibular nystagmus - the intersaccadic interval analysis could be useful.

Balance in elderly patients: the "get-up and go" test.

The "get-up and go test" requires patients to stand up from a chair, walk a short distance, turn around, return, and sit down again. This test was conducted in 40 elderly patients with a range of balance function. Tests were recorded on video tapes, which were viewed by groups of observers from different medical backgrounds. Balance function was scored on a five-point scale. The same patients underwent laboratory tests of gait and balance. There was agreement among observers on the subjective scoring of the clinical test, and good correlation with laboratory tests. The get-up and go test proved to be a satisfactory clinical measure of balance in elderly people.

[ORL selection of French astronauts].

Strict criteria were used, under the control of the Centre National d'Etudes Spatiales (CNES) to select seven French spationautes for future participation in human cargo space flights to take place between 1987-1991 within the framework of the scientific missions of the USA and USSR. Data and results of the clinical O.R.L. examinations and vestibular tests conducted during medical operations of this selection procedure are presented.
