In Patients With Chronic Uraemia it is well known that uraemia is one of the re-asons for polyneuropathy. The subject of this study was to investigate if and how much the uraemia cases autonomic dysfunction. 38 patients with chronic renal failure have been included in the study. Right median nerve motor and sensory conduction. ulnar nerve sensory conduction, peroneal motor conduction and rural nerve sensory conduction have all been recorded from these pa-tients, R-R intervals have also been studied in both during resting and deep inspirium. In addition to that, the sympathetic skin responses evoked by res-piratioit and noise have also been simultaneously from both hands recorded. 56.75% of the patients showed nerve conduction values which indicate polineuropathy. The data re-levant to the R-R inten►ks (during resting %l = 5.58 ± 3.27, during deep inspirium %D = 11.3 ± 5.9, %D-%1= 5.47 ± 5.05. %Dl%1 = 2.19 ± 1.43) have been compared to the values obtained from the control group.1 .The established correlation between R-R intervals and the age of the control group does not exist in the patients with iiremia.2.11 has been found that the %D,%1 and %D-%1 values are sta-tistically different from the values of the control group.The sympathetic skin response could not have been obtained from nine patients(%23_68)_Longer latency values have been observed as compared to the control group. In conclusion it may he surmised that the pa-tients with chronic renal failure show to an im-portant degree an autonomic disfithction (probably due to the autonomic neuropathy) together with polvneuropathy.

Purpose: After a few reports on end-to-side nerve repair at the beginning of this century, the technique was put aside until it has recently been reintroduced by Viterbo. VVe herein present the results of three cases treated by end-to-side median-to-ulnar neurorraphy. Methods: Three patients vvith median nerve defects betvveen 15 and 22cm were treated by end-to-side nerve repair, through an epineurial window. The follow-up times were betvveen 12 and 18 months. Sensory evaluation involved superficial touch, pin-prick, and two poi'nt discrimination tests. Motor evaluation was done by assessing the presence of opposition, and palpating the abductor pollicis brevis. Results: Sensory recovery was observed in ali the patients, in the median nerve dermatome. İn case-3 it was incomplete at the tips of his fingers. Motor recovery vvas absent, except in case-1, who could perform opposition before the operation, as well. Conclusions: End-to-side nerve repair is a viable alternative in cases vvith long gaps betvveen the ends of the injured nerve.

The conduction velocity of the ulnar nerve must be determined in different segments; across elbow, below elbow and above elbow for diagnosis of cubi-tal tunnel syndrome. The test is usually made when the elbow is in full extension. However the position of the elbow seems to influence the conduction ve-locity of the motor axons of the ulnar nerve. In this study we determined motor and mixed nerve conduction velocities of the ulnar nerve in dif-ferent segments-across elbow and below elbow -al dillerent elbow positions (180, 90, 45). We havt found that when the elbow is flexed, the slowing of the motor conduction velocity of the ulnar nerve in across elbow segment is statistically significant. The results are discussed ander the light of the other literatures.
