The medical literature on the evaluation of autonomic dysfunction accumulated discordant results in the past decades, accentuating the need of validating the proposed tests. The Ewing's tests for studying autonomic abnormalities received increasing acceptance, as they recognize not only cardiovascular reflexes damage but lesions in any other segments of the autonomic nervous system. We proposed to validate them in our population by analysing their results on 30 normal individuals and 23 long-standing diabetics. Our results show that the five tests are highly sensitive and specific, reproducible, use simple and available office material, and fulfil their purpose.

We transplanted 6 anatomically abnormal kidneys: a horseshoe kidney that after division was transplanted into 2 recipients; 1 kidney with ureteral stones and hydronephrosis; 1 ectopic and 1 hydronephrotic kidney; 2 kidneys with extensive ureteric lesions, donated as free organs. All these kidneys ultimately had normal function in the recipients, long-term in 4.2 patients died but in neither was the death caused by the renal abnormality.
To obtain some information on porphyrin metabolism in uraemic patients, the activity of erythrocyte uroporphyrinogen I synthetase was measured in patients with chronic renal failure. The results indicate a decreased enzymatic activity which is not due to urea interference, in the hemolysates of these patients.
