[Evaluation of the safety of antitussive agents during respiratory rehabilitation. A clinical study of L-dropropizine].

This study proves that L-dropropizine, a new peripheral antitussive drug, does not hinder the positive and useful effect of cough. This is particularly the case of physiokinesis in chronic obstructive lung disease patients. To quantify results, the respiratory voluntary muscles have been examined by surface electromyography and the peak expiratory flow has been registered by a computer-assisted device.

[Electrophysiologic follow-up (brainstem acoustic evoked potentials and visual evoked potentials) in chronic uremic patients treated with various therapeutic protocols].

The aim of our study was to evaluate the possibility of recording also sub-clinical alterations of the Central Nervous System during chronic uremia by means of the study of Pattern-Reversal Visual Evoked Potentials (P-R V.E.Ps) and Brainstem Acoustic Evoked Potentials (B.

Peripheral nerve conduction velocity in normal infants and children.

Maximum motor conduction velocity of the median, ulnar and peroneal nerves and maximum sensory conduction velocity of the median nerve have been studied in 635 children, below 12 years of age, free from peripheral nervous system disease. The children fell into four age-group: from 0 to 1 year; from 1 to 3 years: from 3 to 6 years; from 6 to 12 years. No normal values were recorded for the sensory conduction velocity of the median nerve under the age of one year.
