Acute reactions to urographic contrast media.
A prospective study of 3509 consecutive patients examined by excretion urography has been conducted to assess the incidence and significance of the untoward effects of urographic contrast media. Four compounds were used in doses containing 160 to 500 mg iodine/kg body weight. Toxic effects, arm pain, and allegic reactions were assessed separately, while the remainder were classified according t...
متن کاملTransplacental passage of insulin complexed to antibody.
The passage of plasma proteins across the placental barrier in humans is known to be highly selective. Thus, free maternal insulin has been reported not to cross the normal maternofetal barrier, although insulin-binding antibodies have been detected in newborn infants whose diabetic mothers received insulin therapy. In this report we demonstrate, with the use of a human antiserum that permits d...
متن کاملA comparison of the clearance of urographic contrast medium (sodium diatrizoate) by peritoneal and haemodialysis.
1. The clearance of isotopically labelled sodium diatrizoate by haemodialysis was measured in vitro, with simulated extracellular fluid, and in vivo in eleven patients, at varying rates of fluid or plasma flow. Clearance was also measured in five patients undergoing peritoneal dialysis. In all instances simultaneous measurements of urea clearance were made and the diatrizoate/urea clearance rat...
متن کاملInvestigating the Complications of Transplacental Needle Passage in Amniocentesis
Background and purpose: Amniocentesis is the most commonly used method for diagnosis of aneuploid and other genetic disorders of the fetus. Cautious should be taken when entering the amniocentesis needle to avoid entering the placenta. The purpose of this study was to investigate the consequences of needle transposition from the placenta during amniocentesis. Materials and methods: In a cohort...
متن کاملTransplacental passage and fetal secretion of aldosterone.
The transplacental passage and the production of aldosterone were studied in late pregnancy during a constant infusion of 1,2-aldosterone-(3)H to mothers at the time of elective cesarean section. It was found that, while maternal aldosterone crossed the placenta, there was a significant secretion of aldosterone by the fetus. The aldosterone concentration in fetal plasma was 2-12 times higher th...
