Pyuria in infancy, and the role of suprapubic aspiration of urine in diagnosis of infection of urinary tract.

Postscript.-Since this paper was submitted for publication J. D. Fewings, M. J. D. Hanna, J. A. Walsh, and R. F. Whelan (Brit. 7. Pharmacol. 1966, 27, 93) have recorded the results of a plethysmographic study of the effects of ethyl alcohol on the blood vessels of the hands and forearms of healthy subjects. Their observations are similar to those reported above for healthy upper limbs. However, they failed to detect any increase in blood-flow in the hand of one patient sympathectomized five years previously or in one patient with a brachial plexus avulsion, and thus inferred that alcohol vasodilatation was sympathetically mediated. In the present investigations all eight sympathectomized upper limbs showed vasodilatation -large in six of them-even shortly after operation, when the denervated hand was hot and flushed compared with the unoperated hand.
