Is Complementary and Alternative Therapy Effective for Women in the Climacteric Period

Vasomotor symptoms start about 2 years prior to menopause in women who are approaching menopause, and early menopause symptoms appear including emotional disturbance and anxiety, followed by physical changes such as vaginal dryness, urinary incontinence and skin wrinkles. As time progresses, osteoporosis, cardiovascular diseases, and dementia occur consecutively. Hormone therapy is primarily considered for the relief of menopause symptoms in postmenopausal women. However, as hormone replacement has emerged as a therapy that increases the potential risk of thrombosis, cerebral infarction and breast cancer, complementary and alternative medicine has drawn much attention. This study aimed to examine the types and effects of evidence-based complementary and alternative therapies that are currently used.

A case of solitary fibrous tumor in the pelvis presenting massive hemorrhage during surgery.

Solitary fibrous tumors (SFTs) are unique soft-tissue tumors of submesothelial origin. These tumors are mainly located in the pleural space but they can be originated within a variety of sites, including the abdomen, the pelvis, the soft tissues and the retroperitoneum. SFTs from all sites are usually benign, and the surgical resection is curative in almost all cases. According to the review of literatures, during the surgical resection, massive hemorrhage could occur due to the hypervascular nature of SFTs. This is a case report on SFT in the pelvis presenting great vessel injury, which resulted in life threatening hemorrhage during the resection of tumor. We wish this paper alerts gynecologists about the risk of massive bleeding during the resection of tumor located at adjacent to great vessels in the pelvis.

An Ethical Issue in Medical Education of Obstetrics and Gynecology

There are four principles of medical ethics; Beneficence, Respect for autonomy, Non-maleficence, and Justice. It is not easy to apply to principles of medical ethics in the special circumstances of obstetrics and gynecology. Student doctors must learn to be familiar with principles of medical ethics tailored to the special circumstances while the obstetrics and gynecology practice.

Expression of Vitamin D Receptor in Seminal Vesicles of Cholesterol Formula Mice

Objectives Genomic function of vitamin D receptor (VDR) indicates spermatogenesis that is important for in male reproductive organ authors evaluated the VDR expression in seminal vesicles with high cholesterol (HC) formula diet rat, because there is no report about relationship or difference in VDR in seminal vesicles between HC and control. Methods Male C57BL/6 mice aged 5 weeks were raised for 13 weeks. After one week of adaptation-period, they were fed different diet on normal AIN-93G diet, or HC diet containing 2% cholesterol for 12 weeks. The antibodies used were rabbit anti-VDR primary polyclonal. Results There was no significant difference in VDR reactivity in seminal vesicles, body weight of rat and weight of seminal vesicles between HC group and normal control group. Conclusion Our data give the no difference in expression of VDR of seminal vesicles rat between HC formula diet and normal AIN-93G diet. But we confirmed the VDR expression in seminal vesicles.

Loss of RUNX3 is significantly associated with advanced tumor grade and stage in endometrial cancers

Loss of runt-related transcription factor 3 (RUNX3) has been reported in various cancers, and one of the mechanisms mediating loss of RUNX3 expression is DNA methylation. However, the role of RUNX3 expression and its DNA methylation status as prognostic factors in endometrial cancer remain unclear. In the present study, the expression and promoter methylation of RUNX3 was examined in endometrial cancer tissues and cell lines, as well as their association with endometrial cancer prognosis. Fifty-five endometrial cancer tissues and two endometrial cancer cell lines (HEC1-α and Ishikawa) were studied. RUNX3 expression and promoter methylation were examined using reverse transcription-polymerase chain reaction (RT-PCR), methylation specific PCR (MS-PCR), and immunohistochemical staining. The demethylating agent 5-aza-2′-deoxycytidine (ADC) was used to reverse the methylation of the RUNX3 promoter. Loss of RUNX3 expression was observed in 50.9% (27/53) of endometrial cancer tissues and in the HEC1-α cell line by immunohistochemistry and RT-PCR, respectively. Methylation of the RUNX3 promoter was observed in 62.2% (33/53) of endometrial cancer tissues, 12.5% (1/8) of normal endometrial tissues, and the HEC1-α cell line by MS-PCR. Tumor grade and stage were significantly correlated with loss of RUNX3 expression. The expression of RUNX3 was restored by treatment with ADC and resulted in growth inhibition in HEC1-α cells. The present results suggested that methylation may serve a critical role in the silencing of RUNX3 and loss of RUNX3 expression may serve as a prognostic marker in endometrial cancer.

Uterine Serous Adenocarcinoma in an Elderly Postmenopausal Woman: Clinically Misdiagnosed as Uterine Cervix Cancer

Uterine serous adenocarcinoma (USC) is rare and invasive cancer. This cancer is more often reported in the ovary, the fallopian tube, and the endometrium than uterine cervix. No matter where the tumor is located, the tumor exhibits similar histological characteristics. So when uterine cancer is proven to be serous adenocarcinoma, it is necessary to see if the tumor originated from ovary or endometrium and invaded the cervix. We report a case of a 73-year-old postmenopausal woman with USC arising near the internal os of endocervical canal, clinically misdiagnosed as uterine cervix cancer.
