Bilateral inferior petrosal sinus corticotropin sampling with corticotropin-releasing hormone stimulation in a pregnant patient with Cushing's syndrome

A patient was diagnosed with Cushings syndrome during her first pregnancy. Bilateral simultaneous inferior petrosal sinus corticotropin sampling with corticotropin-releasing hormone stimulation was performed before transphenoidal pituitary adenomectomy, with successful localization of the pituitary adenoma. Her Cushings syndrome was controlled postoperatively with resolution of hypertension. This case report demonstrates that the procedure of bilateral simultaneous inferior petrosal venous corticotropin sampling can be safely performed during pregnancy.

Normal midtrimester (17-20 weeks) genetic sonogram decreases amniocentesis rate in a high-risk population.

To evaluate a screening protocol using advanced maternal age, triple‐marker screening, and genetic sonography.

Gastroschisis followed by absorption of the small bowel and closure of the abdominal wall defect

The pathogenesis of congenital absence of the small bowel, a rare birth defect, remains unclear. We report a case of gastroschisis diagnosed prenatally by ultrasonography followed by small bowel absorption and the abdominal wall defect closure. Torsion of a gastroschisis and reabsorption with healing of the abdominal wall defect is proposed as a cause of congenital absence of the small bowel.

Estimation of Fetal Weight: Mean Value from Multiple Formulas

Mean fetal weight value from multiple formulas was compared to fetal weight from single formulas. Data were collected on 975 fetuses who had estimation of fetal weight by ultrasonography within 1 week before birth. Improvement in estimation of fetal weight occurred using either the mean value of multiple formulas or the Hadlock BPD/FL/AC, in comparison to fetal volume, BPD/AC, or FL/AC. BPD/FL/AC appeared to provide the best estimate of true weight in terms of overall accuracy and in terms of not showing a trend in either overestimating or underestimating true weight.

Prenatal diagnosis of nonmosaic trisomy 9 and related ultrasound findings at 11.7 weeks

Trisomy 9 is a relatively rare chromosomal abnormality. There have been no reports of first trimester ultrasound findings associated with mosaic or nonmosaic trisomy 9 in the literature. A case of nonmosaic trisomy 9 diagnosed prenatally with ultrasound findings at 11.7 weeks gestation is presented along with associated abnormal ultrasound findings.
