Gynecologic and obstetric investigation

BACKGROUND: Endometriosis is a debilitating disease that affects women of reproductive age and may lead to impaired fertility. Cell attachment, invasion of the underlying tissue, and vascular ingrowth are important processes in endometrial …

BACKGROUND/AIMS: Endometriosis is a benign but chronic disorder associated with pelvic pain and infertility. Enhanced proliferation and reduced apoptosis susceptibility are characteristics of endometriosis. Cordycepin is a poly(A) polymeras…

BACKGROUND: Dienogest demonstrates efficacy for lesion reduction and pain relief in clinical trials of endometriosis. The current study investigated an intraperitoneal animal model of endometriosis to further characterize the effects of die…

AIMS: To measure endometrial volume and endometrial-subendometrial vascularization by 3-D power Doppler ultrasound in patients undergoing cycles of artificial insemination with ovarian stimulation, to evaluate their relationship with patien…

BACKGROUND/AIMS: Deep infiltrating endometriosis is a very painful condition and the mechanism of pain is still poorly understood. Pain and hyperalgesia can partly be explained by an increased number of nerve structures in the painful lesio…

BACKGROUND/AIMS: Perinatal environmental exposure may affect fetal development and reprogram the developing organism for adult-onset disease. In this case-control study, we aimed at assessing this pathogenetic model in endometriosis. METHO…

BACKGROUND/AIMS: This study compared women suffering chronic pelvic pain (CPP) secondary to endometriosis (n = 30) with women experiencing CPP due to either myofascial abdominal/pelvic pain (n = 70) or pelvic adhesions (n = 38) to determine…

BACKGROUND: The nuclear factor-κB (NF-κB) pathway activates many of the target genes that are critical to the initiation and establishment of endometriosis. We sought to examine the potential application of pyrrolidine dithiocarbamate (PDTC…

OBJECTIVE: This study was conducted to determine the clinical significance of serum survivin in ovarian cancer. METHODS: A total of 65 patients with ovarian tumors including 21 epithelial ovarian cancer, 22 benign epithelial ovarian tumor,…

Radical parametrectomy is indicated in cases of undiagnosed early-stage invasive cervical carcinoma discovered after simple hysterectomy performed for a presumed benign disease process. This radical surgical procedure is rarely performed fo…

OBJECTIVE: The aim of this study is to estimate the incidence of endometriosis in a northwestern region of Italy. The potential sources of geographical variations in the incidence of endometriosis within the region are discussed. METHODS: …

Tumor markers have proved to be generally useful for diagnosing and monitoring malignancy. In contrast, high levels of tumor markers disturb us for differing benign disease from malignancy. We had 5 cases with benign disease who showed high…

Pituitary desensitization following infusion of gonadotropin-releasing hormone (GnRH) is measurable if bioactivity instead of immunoreactivity is considered. We hypothesized that GnRH agonist therapy induces the same kind of desensitization…

BACKGROUND: In a university hospital setting, a 25-year-old woman presented with large vaginal and cervical polyps. Past medical history was significant for stage IV endometriosis. Polypectomy was performed and the polyps were histologicall…

No activating mutations in codons 12, 13 and 61 of ras genes nor inactivating mutations in exons 5-9 of the p53 tumor suppressor gene were detected by polymerase chain reaction and single-strand conformation polymorphism methods in either e…

To examine antiestrogenic effects of danazol through the receptor system and to clarify its direct effects on the endometrium in vivo, we applied danazol jelly directly into the rabbit uterine cavity and measured uterine estrogen, progester…

Since not all problems in endometriosis can be studied in the human, there is need of an animal model. We transplanted endometrial tissue of the rabbit into the peritoneal cavity and studied the changes after 12 weeks. At that time the endo…

We measured serum levels of CA 125 in 26 patients with external endometriosis, using CA 125 RIA Kits. The normal range was instituted below 39 U/ml. The mean CA 125 level (+/- SD) was 55.1 +/- 24.9 U/ml in patients with external endometrios…

The uterus-relaxant effect of diltiazem, a recently developed calcium antagonist, was investigated in vitro. 24 myometrial strips dissected from the lower uterine segment during cesarean section showed a statistically highly significant (p …

The calcium antagonist, nifedipine, was used to identify patients with primary dysmenorrhea caused by myometrial hyperactivity. Twelve patients with severe primary dysmenorrhea received an oral loading dose of 30 mg nifedipine on the first …

The present study was undertaken in order to determine the changes in blood levels of lipid peroxide and vitamin E in EPH gestosis. The mean plasma level of lipid peroxide was 0.89 +/- 0.13 nmol/ml for nonpregnant women, while for normal pr…

Mononuclear cell subpopulations from the peripheral blood (PB) and peritoneal fluid (PF) of fertile and infertile women were quantified by flow cytometry using a double-staining monoclonal antibody technique. No differences in the percentag…

We measured CA 125 levels in sera and menstrual blood of subjects with a normal ovulatory cycle and in those with endometriosis. Serum CA 125 levels were higher in the latter, in each phase of the menstrual cycle. The CA 125 levels in patie…

Endometrial thickness was evaluated in apparently normal postmenopausal women by transvaginal ultrasonography and the results were compared with the response to the progesterone challenge test (PCT). A positive correlation between amount of…

Recent evidence suggested that periovulatory treatment with an immunomodulatory agent such as verapamil might be an effective alternative to conventional treatment for endometriosis-associated subfertility. In particular, it has been report…
