Does accuracy and influence of ascorbic acid on glucose-test with urine dip stick in prenatal care?
High ascorbic acid concentrations cause a reduction in the color reaction of urine dip sticks. False-negative test stick measurements can appear in patients with low glycosuria. The rate of glycosuria shows high individual differences and dependent on the concentration of vitamin C. We conclude that dip sticks are not useful in prenatal management.
This is the largest survey to date of patients with refractory severe UC treated with i.v. cyclosporin. The findings confirm the potential value of i.v. cyclosporin in severe UC but its effectiveness in clinical practice is less dramatic than previously reported.
