Homozygous WNT9B variants in two families with bilateral renal agenesis/hypoplasia/dysplasia.

Am J Med Genet A 2021 Jun 19. Epub 2021 Jun 19.

Children's Hospital of Eastern Ontario (CHEO) Research Institute, University of Ottawa, Ottawa, Canada.

WNT9B plays a key role in the development of the mammalian urogenital system. It is essential for the induction of mesonephric and metanephric tubules, the regulation of renal tubule morphogenesis, and the regulation of renal progenitor cell expansion and differentiation. To our knowledge, WNT9B has not been associated with renal defects in humans; however, WNT9B mice have renal agenesis/hypoplasia and reproductive tract abnormalities. Read More

Prevalence and Factors Associated with Meconium-Stained Amniotic Fluid in a Tertiary Hospital, Northwest Ethiopia: A Cross-Sectional Study.

Obstet Gynecol Int 2021 26;2021:5520117. Epub 2021 May 26.

Department of Medical Laboratory Sciences, College of Medicine and Health Sciences, Bahir Dar University, Bahir Dar, Ethiopia.

. Fetal bowel could pass meconium, a green viscous fluid, before or during labour and most intrauterine passage of meconium is associated with several fetomaternal factors that lead to increased risk of perinatal morbidity and mortality. Given that there is a paucity of data, this study was conducted to assess the proportion and associated factors of meconium-stained amniotic fluid (MSAF) in women who came for labour and delivery service in a tertiary hospital.

Proteomic analysis of a murine model of lung hypoplasia induced by oligohydramnios.

Pediatr Pulmonol 2021 Jun 8. Epub 2021 Jun 8.

Department of Pediatrics, Women and Infants Hospital/Warren Alpert Medical School of Brown University, Providence, Rhode Island, USA.

Severe oligohydramnios (OH) due to prolonged loss of amniotic fluid can cause pulmonary hypoplasia. Animal model of pulmonary hypoplasia induced by amniotic fluid drainage is partly attributed to changes in mechanical compression of the lung. Although numerous studies on OH-model have demonstrated changes in several individual proteins, however, the underlying mechanisms for interrupting normal lung development in response to a decrease of amniotic fluid volume are not fully understood.

A Fetus with Imperforate Anus Developing Pulmonary Hypoplasia Triggered by Transient Urethral Obstruction.

Case Rep Obstet Gynecol 2021 13;2021:9950578. Epub 2021 May 13.

Department of Obstetrics and Gynecology, Faculty of Medicine, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo 113-8655, Japan.

Pulmonary hypoplasia is a rare entity in a fetus with imperforate anus. The fetus was diagnosed with high-type imperforate anus with rectourethral fistula based on the dilated fetal bowel and the presence of bowel calcification at 19 weeks of gestation. As gestation advanced, fetal ultrasonography demonstrated development of pulmonary hypoplasia, progressive bowel dilation, and persistent oligohydramnios from 28 weeks of gestation despite a fluid-filled bladder without hydroureter or hydronephrosis.

First Case of a Term Male Born with Aphallia and Complete Urethral Atresia.

Urology 2021 Jun 1. Epub 2021 Jun 1.

Section of Urology, Department of Surgery, Medical College of Georgia-Augusta University, Augusta, GA. Electronic address:

Aphallia is an exceedingly rare condition often associated with an array of genitourinary anomalies. Classically, aphallia was thought to have to co-exist with a urethral fistula for adequate urine outflow to avoid the sequelae of oligohydramnios, while the absence of a fistula has historically been incompatible with life. We report the first case of a prenatally unrecognized aphallia with complete urethral atresia in a full-term baby, without an associated fistula or ectopic urethra. Read More

Fetoscopic laser ablation in twin-to-twin transfusion syndrome: tips for counselling.

Minerva Obstet Gynecol 2021 Apr;73(2):247-252

Department of Maternal and Child Health and Urological Sciences, Sapienza University of Rome, Rome, Italy.

Twin-to-twin transfusion syndrome (TTTS) is a serious complication that affects approximately 10-15% of monochorionic twin pregnancies. The most important role for the development of this condition is the presence of an unbalanced flow through the inter-twin vascular anastomoses. Depending on the number, type and direction of the connecting vessels, blood can be transfused disproportionately from one twin (the donor) to the other twin (the recipient). Read More
