About streamlined brachial dialysis shunts.

The authors modified the technics of fistula forming. In such cases where to create a connection on the forearm is impossible one possible modality is to make it between major vessels on the arm. Streamlined connection was made in seven patients between basilic vein and brachial artery in three cases, between cephalic vein and brachial artery in four. There were two men and five women. The age interval was between 58 and 78 years. The longest observation period is 30 months. Until this time the fistulas were suitable for dialysis and had abundant yield. Because of the number of cases and the observation period has not yet make possible to come to final conclusion their goal was to present technical solution first of all. Their expectation is that with making them streamlined they will manage to create good perfusing and long lasting fistulas.

[Latent vitamin K deficiency in breast-fed infants].

Quick test, coagulation activity of vitamin K-dependent clotting factors, factor II activity by ecarin, levels of factor II immunoreactive antigen and acarboxyprothrombin were examined in two groups of infants, breast-fed and bottle-fed at the ages of one month and 3 months. None of them received vitamin K at birth and later. Acarboxyprothrombin could be demonstrated in about 14% at the both age of life of breast-fed children, but not in the groups of bottle-fed infants. The activity of coagulation factors was significantly lower in the acarboxyprothrombin-positive group compared to the acarboxyprothrombin-negative group. In none of the infants manifest bleeding was observed. No difference in the activities of factors could be detected in the acarboxyprothrombin-negative groups of breast- and bottle-fed children. These data suggest a frequent latent deficiency of vitamin K in breast-fed infants.
