First-trimester NRBC count in maternal circulation: correlation with doppler ultrasound studies.

This study aimed to determine whether the number of nucleated red blood cells (NRBCs) in maternal circulation during the first trimester of pregnancy could identify pregnancies that will have an anomalous Doppler in the second trimester. A total of 85 blood samples were obtained at 11-14 weeks of gestation with mean uterine arterial perfusion index >1.6, as noted by Doppler ultrasonography.

One-stage surgical procedure for congenital dislocation of the hip in older children. Long-term results.

The one-stage procedure described in this article, which has been used in children older than three years of age, is the method of choice in the treatment of late-diagnosed congenital dislocation of the hip. The present authors and their patients have been more than satisfied with the results of this procedure. With femoral shortening as the fundamental step, this method can be applied in high dislocations, as well as in cases of subluxation in which a pelvic osteotomy is indicated, to restore the depth of the acetabulum and to prevent undue pressure on the femoral head, which is the main cause of avascular necrosis, joint stiffness, and failures.
