[Increased residual urine volume after local injection of botulinum A toxin].

After major head trauma, a 28-year-old male patient developed tetraparesis with marked left-sided contractions of the leg adductors. Spasticity was resistant to antispastic drugs and intensive physiotherapy. Therefore, we injected 12.

Stimulation of the ventral intermediate thalamic nucleus in tremor dominated Parkinson's disease and essential tremor.

Based on Benabid's experimental and clinical findings that low-frequency (50 Hz) electrical stimulation of the ventral intermediate thalamic nucleus may increase tremor, while higher frequencies (> 100 Hz) lead to suppression of the tremor, we implanted a stimulation electrode in 33 thalami among 27 patients. Six patients were implanted bilaterally. 23 suffered from Parkinson's disease, 4 from essential tremor.

Initiation of visual-guided random saccades and remembered saccades in parkinsonian patients with severe motor-fluctuations.

We studied the initiation of saccades to visual-guided random time and remembered targets in a group of nine Parkinsonian patients with severe motor fluctuations and in 9 age matched control subjects. In contrast to a marked skeletomotor improvement during the "on" condition, saccadic latencies for both visual-guided random saccades and remembered saccades were increased in the patients during the "on" condition compared to the "off" condition. This result of dissociation between skeletomotor and oculomotor function indicates that common concepts of saccadic initiation in parkinsonian patients do not hold true in patients with severe fluctuations since dopaminergic stimulation seems to increase saccadic latencies in these patients.

[Instrumental diagnosis of peripheral arterial occlusive disease].

The increasing frequency of peripheral occlusive arterial disease in the general population emphasizes the need of suitable methods for early detection of this disease. This overview summarizes the methods of current use of angiologic investigation. Their sensitivity and practicability are critically discussed.
