Transient osteoporosis of the hip in pregnancy associated with generalized low bone mineral density--a case report.

Transient osteoporosis of the hip (TOH) in pregnancy is characterized by severe pain in unilateral or bilateral hips and has been diagnosed as localized osteopenia. However, we evaluated a case of unilateral TOH with generalized profound osteoporosis involving both the hips and the lumbar vertebrae by dual-energy X-ray absorptiometry. The diagnosis was based on the clinical course and confirmed by magnetic resonance imaging.

Relation of prenatal and postnatal status to calcaneus quantitative ultrasound in adolescents.

This study aimed to elucidate the relationship of prenatal and/or postnatal factors, including acquired factors, with the calcaneus stiffness index as measured by quantitative ultrasound (QUS-SI) in adolescents. We recruited 1,143 adolescents with a mean age of 14.8 ± 1.

Maternal weight gain rate in the second trimester are associated with birth weight and length of gestation.

Background: Low total weight gain during pregnancy has been widely accepted as a valid risk factor for small-for-gestational-age infants and pre-term births. However, it is not obvious in which trimester the weight gain rate most affects birth weight and length of gestation.

Method: Using logistic regression analysis and Pearson's correlation coefficient test, data from 472 women who had vaginally delivered an infant at term without any complications were analyzed retrospectively.

Pregnancy complicated with lactate dehydrogenase M-subunit deficiency: the first case report.

A woman with lactate dehydrogenase M-subunit deficiency underwent two cesarean sections because of the risk of dystocia due to decreased adenosine triphosphate production in anaerobic glycolysis including uterine muscles. Frequent pains with increased serum pyruvate levels were observed during the third trimester of her pregnancies.
