Preoperative OPN is a useful biomarker for predicting ovarian cancer. It is especially useful when used complementary to CA125. Larger studies of patients with ovarian cancer showing a low CA125 level or in early stages of ovarian cancer are needed.

A case of a 23-year-old, nulliparous female with a very rare isolated adenomyotic cyst inducing severe dysmenorrhea was seen. Transvaginal ultrasonographic tomography and magnetic resonance imaging (MRI) showed a 3 x 3-cm cystic mass within the left anterior wall of the uterine corpus. The cystic space was filled with hyperintense fluid on T1-weighted images, which was surrounded by hypointense tissue beside the right uterine corpus on T2-weighted images. The case was preliminarily diagnosed using MRI as having cavitated rudimentary uterine horn. However, hysterosalpingography excluded the possibility of uterine anomaly. A hemorrhagic adenomyotic cyst measuring 3 cm within the left anterior wall of the uterine corpus was surgically removed. There was no evidence of diffuse adenomyosis uteri. Dysmenorrhea completely disappeared postoperatively.

An initial event during the menopausal process is BMD loss, which is followed by body fat distribution shift, then LBM loss and reciprocal increase in body fat mass.

Leptin is not a key regulator of bone metabolism, although it may have some effects on bone metabolic markers and BMD regionally in premenopausal women.

It is important to elucidate whether the leptin receptor, especially the long signal-transducing form of the leptin receptor (OB-Rb) is expressed in human osteoblasts. We detected the expression of human OB-Rb in cultured commercially available human osteoblasts (NHOst cells) using real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR). After confirming the expression of OB-Rb, we investigated the effect of leptin on NHOst cells. Leptin enhanced cell proliferation of the cells shown by the MTT assay. Furthermore, leptin changed the copy numbers of Bax and Bcl-2 mRNAs in the cultured cells as shown by real-time quantitative RT-PCR, although the effect was not consistent. Leptin did not change the production of osteocalcin and osteopontin by the cells. Leptin did not change the expression of OB-Rb mRNA in the cells. In conclusion, OB-Rb mRNA is expressed in cultured commercially available human osteoblasts. Leptin may have some effects on bone metabolism by directly modulating cell proliferation and apoptosis of osteoblasts in humans.

Aging rather than menopause contributes to the increase in the percentage of trunk fat mass. However, the percentage of leg fat mass does not change with aging. Upper body fat distribution in postmenopausal women may be more attributable to aging than to menopause.
