Effect of Childbirth Age on Bone Mineral Density in Postmenopausal Women.

Background: In postmenopausal women, there is rapid bone loss due to estrogen depletion. In women, reproductive factors such as age at menarche, breastfeeding, and parity are considered risk factors of osteoporosis. Many reports suggest that obesity is associated with a reduced risk of osteoporosis.

Effect of Maternal Age at Childbirth on Obesity in Postmenopausal Women: A Nationwide Population-Based Study in Korea.

The object of this study was to assess the obesity in postmenopausal women, according to age at childbirth.We analyzed the association between age at first childbirth, age at last childbirth, parity, and subject obesity status (general obesity; BMI >25 kg/m, nongeneral obesity; BMI ≤25 kg/m, abdominal obesity; waist circumference >85 cm, nonabdominal obesity; waist circumference ≤85 cm), using data from a nationwide population-based survey, the 2010 to 2012 Korean National Health and Nutrition Examination Survey. Data from a total of 4382 postmenopausal women were analyzed using multivariate regression analysis with complex survey design sampling.

Fetal primary small bowel volvulus in a child without intestinal malrotation.

Fetal primary small bowel volvulus without atresia or malrotation is an extremely rare but life-threatening surgical emergency. We report a case of primary small bowel volvulus that presented as sudden fetal distress and was diagnosed on the basis of the 'whirl-pool sign' of fetal sonography. This diagnosis led to emergency operation after birth at the third trimester with a good outcome.

Usefulness of additional fetal magnetic resonance imaging in the prenatal diagnosis of congenital abnormalities.

Objective: Our aim was to compare the value of fetal magnetic resonance imaging (MRI) with detailed ultrasound in the prenatal diagnosis of congenital abnormalities.

Materials And Methods: This retrospective study reviewed the medical records of pregnant women and their neonates who, after ultrasound, were suspected to have congenital abnormalities. They then underwent a detailed ultrasound examination and a fetal MRI in our institutions.

Maternal outcomes according to placental position in placental previa.

Purpose: The purpose of this retrospective cohort study was to elucidate whether the location of placenta below uterine incision in cesarean section is important in the development of maternal complications in placenta previa patients.

Methods: The study was conducted on 409 patients 414 parturition at 3 hospitals in affiliation with the Catholic Medical Center, Seoul, Korea from May 1999 to December 2009. The subjects were divided to two groups: the group whose placenta was located in the anterior portion of the uterus (anterior group) and the group whose placenta was located in the posterior portion of the uterus (posterior group).

Optimal gestational age of delivery to decrease neonatal morbidity in preterm pregnancies in Korea.

Aims: Preterm birth is the most common cause of neonatal morbidity and mortality. Neonatal morbidity and mortality are known to decrease significantly after 34 weeks in preterm births following preterm labor, and after 32 weeks in preterm births following preterm rupture of the membranes. However, these outcomes may not apply to Korean preterm neonates.
