Measurement of blood pressure and heart-rate variation while resting supine and standing for the evaluation of autonomic dysfunction.

Blood pressure and R-R interval variation were studied during postural changes using a tilting table. The subjects were 64 normal controls and 52 patients with various disorders. None of the normal controls showed postural falls of more than 15 mm Hg in mean blood pressure. The mean loge coefficient of variation of 100 R-R intervals was significantly reduced in groups with Parkinson's disease, spinocerebellar degeneration, Shy-Drager syndrome and diabetes mellitus, compared with a normal control group. Reduced heart-rate variation was frequently associated with sphincter disturbance and orthostatic hypotension.

[The supinator syndrome--an anatomical and clinical study].

The interosseus posterior syndrome appears in two forms: a) the paralytical interosseus posterior syndrome, b) the painful (afferent) interosseus posterior syndrome. We report in this investigation about 12 operated patients with painful interosseus posterior syndrome. The intraoperative findings in the arcade of Frohse are compared with the findings we made at the preparation of 10 recently deceased. It was especially significant, that we found in 10 of our 12 cases intraoperatively a tendinous type of arcade. In our directioned cases we encountered this type of tendinous arcade in only 2 of 10 cases. Based on these findings we are of the opinion that the tendinous arcade of Frohse is an important factor in the development of the interosseus posterior syndrome.

Lack of association between transiently evoked otoacoustic emission amplitude and experimentation linked-factors (repeated acoustic stimulation, cerebrospinal fluid pressure, supine and sitting positions, alertness level).

Changes in transiently evoked otoacoustic emissions (TEOAEs) occur during sleep and during tasks requiring attention. This can be due to a central nervous system effect on the cochlea. But, an additional or dominant influence by non-controlled factors is possible. In this paper, the effect of click-stimulus repetition, lying and sitting positions, state of alertness (awake or asleep) and CSF pressure variation on TEOAE features were studied. None of these factors affected TEOAE amplitude. In 2 subjects, TEOAE amplitude increased considerably during the night while remaining stable in 7 subjects during daytime sleep. This may be due to circadian variations of TEOAE amplitude.
