OBJECTIVE Androstenedione (A4) is an androgen that can be metabolized by aromatase to estrone, but the effects of A4 on endometrial cell proliferation either as an androgen or via conversion to estrogens are unknown. The aim of this study was to investigate A4 effects on Ishikawa cells in culture. STUDY DESIGN Ishikawa cells were treated with increasing(More)
Primary ovarian pregnancy is very rare event after natural pregnancy or assisted reproductive technology (ART) procedures. Although there are a few reports about unilateral ovarian pregnancy after in vitro fertilization and embryo transfer (IVF-ET), there has been no report about bilateral ovarian pregnancy. Moreover, it is difficult to diagnose an ovarian(More)
Lipoleiomyoma is an uncommon neoplasm of the uterus, composed of smooth muscles intermixed with mature adipocytes. These tumors are considered a benign variant of uterine leiomyomas. Herein, we report six cases of lipoleiomyoma experienced in our institution from January 2005 to March 2015. The patients ranged in age from 45 to 70 years; the etiology may be(More)
With rising concerns of heavy metal exposure in pregnancy and early childhood, this study was conducted to assess the relationship between the lead, cadmium, mercury, and methylmercury blood levels in pregnancy and neonatal period. The study population included 104 mothers and their children pairs who completed both baseline maternal blood sampling at the(More)
Endometrial cancer is a significant malignancy in developed countries. Unopposed estrogen stimulation is considered as an important risk factor for endometrial cancer. Epigallocathechin-3-gallate (EGCG), biological active component of green tea, inhibits cancer cell proliferation. However, it is unknown whether EGCG has anticancer effects on endometrial(More)
Superficial angiomyxomas (SAMs) are rare benign cutaneous tumors that involve the subcutaneous layer. They are commonly located in the trunk, lower limbs and head or neck of women of reproductive age. SAMs in the vulva of postmenopausal women are especially rare case. Herein, we report a vulvar SAM in a postmenopausal 60-year-old woman. The patient(More)
OBJECTIVE The objective was to determine the direct effect of letrozole on the proliferation and apoptosis of cultured leiomyoma cells co-treated with prostaglandin E(2) (PGE(2)). STUDY DESIGN Leiomyoma cells were obtained from three groups of patients who had undergone hysterectomy due to leiomyoma. Percentages of antiproliferative cells were evaluated(More)
Lymphoepithelioma-like carcinoma (LELC) in the uterine cervix is a very rare variant of squamous cell carcinoma and accounts for 0.7% of all primary malignant neoplasms. The pathogenesis of LELC in the uterine cervix is unclear but some studies have reported association with human papilloma virus (HPV) in Western women and EpsteinBarr virus (EBV) in Asian(More)
Ovarian hyperstimulation syndrome (OHSS) includes ovarian enlargement and ascites. It is usually mild but can be, rarely, fatal. Deep vein thrombosis (DVT) is among the potentially fatal complications of OHSS. During pregnancy, DVT is more common in the lower extremities than in the upper part of the body, but OHSS-related DVT occurs more frequently in the(More)
OBJECTIVE This study was performed to identify whether growth and differentiation factor-9 (GDF-9) and transforming growth factor-β1 (TGF-β1) expressions would be lower in the follicular fluid (FF) of those over age 35 who underwent IVF than under age 35. METHODS A total of 24 IVF cycles (20 patients) were included in this study. All of patients were(More)
