Objective: To evaluate the potential relationship between placental disruption in weeks 13 and 14 and the subsequent development of gestational hypertension or preeclampsia.
Methods: Using subjects recruited during a randomized trial funded by the National Institute of Child Health and Human Development, which compared early amniocentesis and late transabdominal chorionic villus sampling (CVS) in weeks 13 and 14, rates of gestational hypertension and preeclampsia were compared between cases with varying degrees of placental disruption.
Results: A total of 3,698 of 3,775 randomized subjects had cytogenetically normal pregnancies and were analyzed. A significantly higher rate of hypertension/preeclampsia was observed in the late CVS group (5.4%, n = 1,878) compared with the early amniocentesis cohort (3.5%, n = 1,820; P = .005). This difference persisted after controlling for maternal age, body mass index, parity, previous preterm delivery, smoking, and fetal gender. Early amniocentesis cases were further stratified on the basis of whether the placenta had been penetrated (n = 460) or not (n = 1,360). Risk of hypertensive complications was lowest if the placenta was not traversed (3.4%), greater with placental penetration (3.9%), and highest when the placenta was directly sampled during CVS (5.4%, P = .02).
Conclusion: We hypothesize that focal disruption of the placenta at 13-14 weeks may increase the risk of hypertension/preeclampsia. These findings provide support for the theory that disturbances in early placentation lead subsequently to maternal hypertension.

Background: Mucopolysaccharidosis type I (MPS I - IDUA gene) is a rare autosomal recessive lysosomal storage disorder. Clinical symptoms, including visceral overload, are progressive and typically begin postnatally. Descriptions of hepatosplenomegaly associated with lysosomal pathology are uncommon during the prenatal period.

Background: Prenatal cell-free DNA (cfDNA) screening is a success story of clinical genomics that has translated to and transformed obstetric care. It is a highly sensitive and specific method of screening for the most common fetal aneuploidies, including trisomies 13, 18, and 21. While primarily designed to detect fetal chromosomal abnormalities, the test also analyzes maternal cfDNA, which can complicate interpretation of results.

Background: Currently, it is recommended to arrange screening for all women who are referred for prenatal care before the 20 week of gestation. Congenital and genetic diseases lead to disability and death in 3% of babies. Prenatal diagnosis is the only way to prevent the birth of babies with genetic disorders.

Rationale: The aim of this study is to investigate the de novo mutation and clinical features of latent transforming growth factor-beta-binding protein 3 (LTBP3) gene-associated geleophysic dysplasia 3, and possible mechanisms of action.
Patient Concerns: A nonconsanguineous couple was recruited for this study due to the presence of intrauterine growth restriction. The pregnant woman and her elder daughter presented with skeletal abnormalities with diabetes.
