The association between adenomyosis and uterine torsion, a rare, serious obstetric condition, remains unclear and has not been systematically investigated. This study aimed to elucidate the incidence, risk factors, and clinical characterist…

BACKGROUND: Endometriosis is a chronic, estrogen-dependent inflammatory disorder and a leading cause of female infertility. Ovarian endometriomas, a common manifestation of endometriosis, are commonly associated with diminished ovarian func…

Only a few human ovarian endometrioid carcinoma cell lines are currently available, partly due to the difficulty of establishing cell lines from low-grade cancers. Here, using a cell immortalization strategy consisting of i) inactivation of…

BACKGROUND: Chronic low-grade inflammation is increasingly recognized as a contributing factor to female infertility. Elevated levels of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-6 are observed in ovarian conditions including …

Vaginal cuff dehiscence (VCD) is a rare complication of total laparoscopic hysterectomy (TLH); the incidence rate has been reported to be 1.27%. However, a definitive treatment strategy has not yet been established. To our knowledge, we rep…

Objective: To elucidate the incidence, risk factors, and clinical characteristics of uterine torsion in pregnancies complicated by adenomyosis, which remains unstudied to date. Design: Retrospective cohort study. Setting: University Hospita…

A human ovarian clear cell carcinoma cell line was established from a 46-year-old Japanese woman. That line, designated MTC-22, has proliferated continuously for over 6 months in conventional RPMI 1640 medium supplemented with 10% foetal bo…

BACKGROUND Spontaneous hemoperitoneum in pregnancy (SHiP), defined as nontraumatic, acute intra-abdominal bleeding during pregnancy or the postpartum period, is a serious life-threatening complication to mother and child. Endometriosis is a…

The ovarian microenvironment is critical for follicular development and oocyte maturation. Maternal conditions, including polycystic ovary syndrome (PCOS), endometriosis, and aging, may compromise the ovarian microenvironment, follicular de…

Ovarian cancers derived from endometrial cysts, also known as endometriosis in ovaries, are widespread histological types in Japan. Several studies suggest that zinc deficiency plays a role in endometriosis; however, the biological mechanis…

The dynamical network biomarker (DNB) theory detects the early warning signals of state transitions utilizing fluctuations in and correlations between variables in complex systems. Although the DNB theory has been applied to gene expression…

Although subcutaneous emphysema is a common benign complication of laparoscopic surgery, airway obstruction can occur due to pharyngeal emphysema when it extends to the neck. Here, we report a case of subcutaneous emphysema extending to the…

Herlyn-Werner-Wunderlich syndrome (HWWs) is a rare congenital malformation that involves uterus dideslphys, obstructed hemivagina and ipsilateral renal agenesis. The obstructed vagina affects menstrual flow and causes related clinical featu…

ObjectiveTo examine the association between ovarian conservation and oncologic outcome in surgically-treated young women with early-stage, low-grade endometrial cancer.MethodsThis multicenter retrospective study examined women aged <50 with…

Spontaneous hemoperitoneum in pregnancy (SHiP) has mainly been discussed in the context of endometriosis. With hormonal changes and enlargement of the uterus during pregnancy, tumors can also increase the chance of rupture and consequent SH…

Background and objectivesThe Rosemont classification (RC) was developed as a consensus-based standard for the diagnosis of chronic pancreatitis (CP) by endoscopic ultrasonography (EUS), however, it is more complicated than the conventional …

PURPOSE: We performed TaqMan genotyping assays of anti-Mullerian hormone (AMH) and anti-Mullerian hormone receptor type II (AMHRII) single nucleotide polymorphisms (SNPs) in order to investigate how their frequency and distribution affect i…

PurposeExamination of the mitochondrial mRNA expression in granulosa cells from an unspecified population of infertile patients to evaluate whether recombinant follicle stimulating hormone (recFSH) is more effective in producing higher qual…

OBJECTIVE: To evaluate how endometriosis affects the expression of estrogen and progesterone receptors mRNA in granulosa cells. DESIGN: Prospective study. SETTING: IVF-ET program at Osaka Medical College. PATIENT(S): Eighteen patients wi…
