PROBLEM: The pathogenesis of endometriosis remains unclear. Endometrial cells in retrograde menstruation are considered the source of endometriosis; therefore, we hypothesized that the eutopic endometrium may provide clues regarding the pat…

ObjectiveThis study aimed to review the effect of endometriosis on the prevalence of placenta previa and postpartum hemorrhage in pregnant patients and the surgical outcomes of pregnant patients with endometriosis developing placenta previa…

Abstract Objective: Circulating cell-free tumor DNA (ctDNA) is fragmented DNA released from cancer cells into the circulation. Technological development of digital PCR allows us to detect a small quantity of ctDNA in the circulation, sugges…

Causal inference is one of the challenges in epidemiologic studies. Gynecologic diseases have been reported to have association with obesity, however the causality remained controversial except for uterine endometrial cancer. We conducted t…

We performed genome-wide association studies of five gynecologic diseases using data of 46,837 subjects (5236 uterine fibroid, 645 endometriosis, 647 ovarian cancer (OC), 909 uterine endometrial cancer (UEC), and 538 uterine cervical cancer…

AIM: The aim of this study was to report the pregnancy outcomes of women who received different doses of corticosteroid supplementation during labor and delivery. METHODS: We conducted a retrospective review of 102 pregnant women who receiv…

Lymphangioleiomyomatosis (LAM), a rare multisystem disease affecting mainly young women, is characterized by an abnormal proliferation of smooth muscle-like cells in the lungs. We report a case of endometriosis with chronic pelvic pain due …

Clear cell carcinoma (CCC) of the ovary is known to show poorer sensitivity to chemotherapeutic agents and to be associated with a worse prognosis than the more common serous adenocarcinoma or endometrioid adenocarcinoma. To improve the sur…

To assess the effect of dienogest on recurrence of ovarian endometriomas and severity of pain after laparoscopic surgery, a retrospective study of 81 patients was performed at three institutions in Osaka, Japan. Patients had a six-month min…

Clear cell adenocarcinoma (CCC) is generally thought to originate from ovarian, endometrial, or renal tissue. A CCC of the peritoneum (CCAP) is an extremely rare medical condition and is associated with a poor prognosis. To date, only 10 ca…

OBJECTIVE: Although fibroids greatly affect reproductive health, the pathophysiology and epidemiology are not well known. Recently, we have reported the relationship between uterine leiomyoma and metabolic syndrome. Many studies have indica…

OBJECTIVE: Uterine leiomyomas are the most common gynaecological benign tumour and greatly affect reproductive health and wellbeing. They are the predominant indication for hysterectomy in premenopausal women. Curcumin, a well-known compone…

ObjectiveTo clarify the frequency of pregnancy complicated by ovarian endometriosis and to investigate the size change and outcome of ovarian endometriosis during pregnancy.DesignRetrospective study.SettingDepartments of obstetrics and gyne…

OBJECTIVE: Uterine leiomyomas are the most common gynecological benign tumor and greatly affect reproductive health and well-being. They are the predominant indication for hysterectomy in premenopausal women. Current epidemiological study r…

OBJECTIVE: The objective of the study was to evaluate the presence of fractalkine in the endometrium of the uterus and the change of fractalkine protein levels during menstrual cycle. METHODS: Twelve samples of endometrium of the uterus wer…

ObjectiveSecretory leukocyte protease inhibitor (SLPI) is a potent inhibitor of human leukocyte elastase. The aim of the present study was to examine whether there is an association between the SLPI concentration in the cervicovaginal secre…
