Summary
Placental abnormalities are linked to small-for-gestational-age (SGA) neonates. Gestational hypertension is a primary clinical cause of SGA, impacting fetal growth.
Area of Science:
- Obstetrics and Gynecology
- Perinatal Medicine
- Pathology
Context:
- Small-for-gestational-age (SGA) neonates represent a significant concern in perinatal care.
- Understanding the placental factors contributing to SGA is crucial for improving neonatal outcomes.
Purpose:
- To investigate the association between pathological placental findings and the occurrence of small-for-gestational-age neonates.
- To identify specific placental abnormalities prevalent in SGA cases compared to appropriate-for-gestational-age controls.
Summary:
- A comparative study examined 100 placentas from SGA neonates and 200 from appropriate-for-gestational-age (AGA) neonates.
- SGA placentas exhibited lower volume, weight, and fetal-placental weight ratio, with increased incidence of umbilical cord abnormalities, syncytial knots, avascular villi, and villous infarcts.
- Gestational hypertension and abnormal fetal monitoring were more frequent in the SGA group.
Impact:
- Gestational hypertension disease is identified as a major clinical cause of SGA.
- Specific placental abnormalities can adversely affect intrauterine fetal growth and development, highlighting the placenta's critical role.

Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...

Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
