Twin pregnancy after renal transplant: the first case report in Thailand

Abstract

Background: With more advanced technology, the renal transplant women have more chance to get pregnant, even multiple gestations. Obstetricians need the knowledge to provide the better care for these patients. Objective: Report the natural course of disease and the intervention for renal transplant woman with twin pregnancy. Patient and methods: A 20-year-old primigravida who underwent living-related renal transplantation eight months before pregnancy with monochrorionic diamniotic twins was treated throughout her pregnancy. Results: At 30 weeks of gestation, the patient was admitted due to rising of creatinine level, high blood pressure, and proteinuria. After conservative treatment for 12 days, the pregnancy was terminated by cesarean section with tubal resection. Both alive twins weighed 1385 g and 1525 g. Allograft kidney biopsy was undertaken, and histologic examination showed acute rejection. The renal function gradually improved after one month of antirejection therapy. Conclusion: The complications of pregnancy and poor perinatal outcomes are higher in renal transplant recipients. A multidisciplinary team is required for the management of these patients.

Relationship between type and weight of placenta and neonate birth weight in twin pregnancy

Abstract

The relationship between the type and size of placenta and the development of twin fetuses is still discussed in perinatology. The objective of this paper is to answer the question whether the final weight and size of placenta is a limiting factor for fetal growth in twin pregnancy. The study material consisted of 1,261 pairs of fetuses from monochorionic (MC) and dichorionic (DC) twin pregnancies, born by cesarean section between pregnancy weeks 22 and 41 at the Perinatology and Gynecology Department of the Poznan University of Medical Sciences between 2003 and 2009. Histological examination of secundines, placental weights, and birth weight of twins were evaluated, and the newborn condition was assessed by the Apgar score. Statistical evaluation by analysis of variance assessed placental growth related to gestational age and also the effect of placental-fetal weight ratio on neonate clinical condition. We observed an increase in placenta growth until 38 weeks of pregnancy in twins sharing one placenta and until 36 weeks of pregnancy in twins with separate placentas. Between 22 and 35 weeks of pregnancy, the placental-fetal weight ratio in twins sharing one placenta was higher and they were also smaller than twins with separate placentas The placental-fetal weight ratio was comparable in all twins at delivery and was associated with the clinical condition of newborns. Newborns who received an Apgar score of 8 or more 10 minutes post delivery had a lower ratio than neonates with Apgar score equal to or lower than 7 (p≤0.01). Although these latter twins had both smaller placentas and smaller birth weights, their placental-fetal weight ratios were significantly higher than those of twins born in good condition. Placental growth decreases before pregnancy term but does not limit fetal birth weight in twin pregnancy.

Cytogenetic and Molecular Diagnostics of XX/XY Chimerism in Cattle, Sheep, and Goats – A Review

Abstract

Animal cell chimerism denotes the presence of two or more cell lines of different genetic origin. The most common form of chimerism, which occurs spontaneously in mammals, is the presence of two or more cell populations in animals derived from dizygotic twin or multiple pregnancies. The aim of this review is to present extensive information on XX/XY chimerism in cattle, sheep and goats from the Bovidae family. Additionally, it will discuss a methodology for a quick and accurate diagnosis of cell chimerism and make an analysis of cells obtained from gonads of animals derived from twin pregnancies which underwent an exchange of hematopoietic tissue as a result of anastomoses. The studies reviewed here led the authors to conclude that XX/XY chimerism is generally undesirable in livestock breeding. Females (freemartins) are infertile, whereas in male carriers of chimerism, the impact of this abnormality on sperm parameters is still under discussion, therefore every case of different-sex twin or multiple births should be analyzed individually.
