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.

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.

We report an extraordinarily rare case of uterine leiomyosarcoma with metastasis to the pancreas following initial metastasis to the lung, both of which were diagnosed using histology and immunohistochemistry of the specimens obtained at surgery.

A case of intestinal volvulus in both the sigmoid colon and cecum in a pregnant woman suffering from severe constipation is reported herein. The fetus was dead and the mother developed acute shock. The twisted sigmoid colon coiled twice around the uterus and was perforated. The mother died 10 h after the onset of severe abdominal pain. Volvulus should be considered when examining severe abdominal pain in a pregnant woman with a history of severe constipation. Early suspicion together with prompt intervention will minimize maternal and fetal morbidity and mortality of this rare complication of pregnancy.

Estrogen receptor alpha polymorphisms, but not beta3-adrenergic receptor gene, may be associated with a risk of endometrial cancer.
