The Stillbirth Collaborative Research Network recently reported on the probable or possible cause of death of 512 stillbirths whose mothers consented to complete postmortem examination [1]. Umbilical cord accidents (UCA) represented 10% of stillbirths [1]. In Caucasians the UCA associated stillbirth rate was 13% and 4% in non-Hispanic black. 9% of stillbirths were due to hypertension and 8% due...

Umbilical cord blood is the baby's blood left over in the umbilical cord and placenta after a baby is delivered and the cord is cut. Cord blood has all of the features of regular blood, but it is also a rich source of hematopoietic stem cells. Hematopoietic stem cells are unspecialized cells that produce all blood cells. These include: • Platelets, which are needed for blood clotting • Red...

Fifty umbilical cords were prepared and examined and their venous perfusion pressures measured with and without a true knot in the cord. Contrary to information in the literature, a loose umbilical cord knot did not affect the venous perfusion pressure. With a tightened knot, the smaller the umbilical cord diameter, the greater was the pressure required to perfuse past the knot. The umbilical v...

INTRODUCTION Many abnormalities are observed in the morphology and pathology of the umbilical cord. The aim of the study was to assess the role of 3D sonography in pathology of true umbilical cord knots. MATERIAL AND METHODS In our materials we observed 10 cases of true umbilical cord knots in a population of 2,864 deliveries. The 2-dimensional transverse scan of the umbilical cord was shown ...

An 'exomphalos' is a herniation of abdominal viscera into the umbilical cord; the sac consists of two layers of tissue: the inner, the peritoneum, and the outer, the amnion, which are fused together to form a thin and avascular membrane. From published reports and from examination of the defect in various patients, the condition is divisible into two types which resemble one another only superf...

OBJECTIVE To compare selected umbilical cord parameters, especially cord coiling, between breech and vertex presentations. METHODS We prospectively collected umbilical cords from uncomplicated breech and vertex obtained during elective term cesarean deliveries. We compared various cord parameters between the two groups as well as data regarding obstetric history and pregnancy outcome. RESUL...

BACKGROUND There are no definitive markers to aid in diagnosis of neonatal encephalopathy (NE). The purpose of our study was (1) to identify and evaluate the utility of neuronal nitric oxide synthase (NOS1) in umbilical cord blood as a NE biomarker and (2) to identify the source of NOS1 in umbilical cord blood. METHODS This was a nested case-control study of neonates >35 weeks of gestation. E...

purpose : our aim was to isolate mesenchymal stem cells (mscs) from mouse umbilical cord and culture them with vitreous body to investigate their capacity to differentiate into lens fiber cells, crystallins are expressed. methods : wharton's jelly is the appropriate source of mscs. after isolation, the cells were cultured and alkaline phosphatase detection kit was used for staining undiffe...

BACKGROUND Umbilical cord infection developing subsequent to bacterial colonization is one of the outstanding reasons of newborn mortality and morbidity in underdeveloped and developing countries. OBJECTIVES This study aimed to evaluate the influence of sponge and tub bathing methods on umbilical cord separation time in full term babies in Turkey. PATIENTS AND METHODS This quasi-experimenta...
