Insulin-like growth factor-1 isoform mRNA expression in women with endometriosis: eutopic endometrium versus endometriotic cyst.

Pathogenesis of endometriosis involves growth factors, which are synthesized locally. Insulin-like growth factor-1 (IGF-1) prevents apoptosis and has mitogenic action on endometrial cells. The IGF-1 gene undergoes alternative splicing and results in three isoforms (IGF-1Ea, IGF-1Eb, and IGF-1Ec or MGF).

FSH receptor gene polymorphisms have a role for different ovarian response to stimulation in patients entering IVF/ICSI-ET programs.

Purpose: To examine the frequency distribution of the Ser680Asn polymorphism of the follicle-stimulating hormone receptor (FSHR) gene in ovarian dysfunction (OD) infertile women, "poor responders" (PR) and "good responders" (GR).

Methods: The hormonal profiles and treatment of all patients were analyzed and FSHR polymorphism was examined by PCR and RFLP. Women from all groups were classified as Asn/Asn, Asn/Ser, and Ser/Ser genotypes.

Laparoscopic evaluation of infertile patients with chronic pelvic pain.

In this study over a 10-year period, 1584 patients complaining of infertility of more than 1 year duration were evaluated for their laparoscopic findings in relation to the presence or not of chronic pelvic pain (CPP). Infertility was the only complaint in 1215 cases (group 1), whereas 369 patients complained of infertility and CPP (group 2). All cases underwent routine infertility investigation and pelvic ultrasonography, followed by diagnostic laparoscopy, with infertility-only cases acting as a control group.

The aim of this study was to investigate the effect of human hydrosalpinx fluid (HF) on the development and blastulation of mouse embryos and the role of the concentration of growth factors in culture medium with and without HF. In total, 2100 mouse embryos were cultured. Female mice were induced to superovulate and then mated with males.

Comparison between "short" and "long" protocols in an ICSI programme.

In the present retrospective study we compare the efficacy of gonadotropin-releasing hormone (GnRH) agonist in a long protocol and a GnRH agonist in a short protocol administration for controlled ovarian hyperstimulation (COH) in an ICSI program. A total of 424 consecutive patients with a history of male factor were included in the present study. Three hundred and three patients were included in the long protocol and 121 in the short protocol.

Prolactin receptor mRNA expression in oocytes and preimplantation mouse embryos.

Prolactin was first identified as an anterior pituitary lobe hormone, responsible for the regulation of mammary gland growth and development. Prolactin receptors have been localized in a number of peripheral tissues, including tissues involved in reproduction. Studies with knockout animals have shown that prolactin receptor deficient mice present reproductive defects, whereas prolactin promotes the developmental potential of preimplantation mouse and rat embryos in vitro.

Coexistence of verrucous and squamous carcinoma of the vulva.

Aim: To evaluate the coexistence of verrucous and squamous carcinoma of the vulva and to assess the clinical course, survival and rate of recurrent disease of these patients.

Methods: The records of 17 patients who were diagnosed with verrucous carcinoma of the vulva over a 12-year period were studied retrospectively. Presence of genuine verrucous carcinoma or coexistence of verrucous and squamous carcinoma of the vulva on vulvar biopsies, results of histopathological assessment of final vulva and inguino-femoral node specimens and histological evaluation of recurrent disease specimens were the main outcome measures.

Primary malignant mesothelioma of the peritoneum: a clinical and immunohistochemical study.

Background: Primary peritoneal mesothelioma is regarded as a fatal disease that presents with progressive ascites at a relatively late stage of its natural history. Differential diagnosis between this rare tumor and both serous papillary carcinoma of the peritoneum and ovary can be problematic.

Laparoscopic treatment of ovarian dermoid cysts: eleven years' experience.

Study Objective: To compare laparoscopic and open approaches in the management of benign ovarian teratomas (dermoid cysts) with regard to operative outcome, complications, and postoperative follow-up. Factors that predispose to rupture of dermoid cysts during laparoscopic removal and rates of adhesion formation in women with and without cyst rupture during laparoscopic surgery also were considered.

Design: Review of cases of women with dermoid cysts who underwent cystectomy either by laparoscopy or laparotomy in our department from 1992 through 2002 (Canadian Task Force classification III).

A modified gonadotropin-releasing hormone (GnRH) antagonist protocol failed to increase clinical pregnancy rates in comparison with the long GnRH protocol.

The purpose of this prospective randomized study was to compare stimulation characteristics and IVF outcomes of the standard long GnRH agonist protocol for ovarian stimulation with a modified GnRH antagonist protocol. Starting GnRH antagonist in a flexible protocol according to the size of the leading follicle, with simultaneous augmentation of 75 IU recombinant FSH, failed to increase clinical pregnancy rates.

Pregnant women of 35 years of age or more: maternal serum markers or amniocentesis?

The aim of this prospective study was to compare triple test screening (alpha-fetoprotein, beta-chorionic gonadotrophin and unconjugated oestriol) with amniocentesis in the detection of fetuses with Down's syndrome in women of 35 years of age or more. Between 1992 and 1996, maternal serum markers were evaluated in 1406 women who had amniocentesis for prenatal diagnosis of chromosomal abnormalities related to a maternal age of 35 or more years. Sixteen fetuses with Down's syndrome were identified in the whole group by amniocentesis and karyotyping.

Background: Infection of the chorioamnion with Ureaplasma urealyticum has been associated with low birth weight. Respiratory tract colonization in preterm infants has been associated with the development of chronic lung disease (CLD). The purpose of the present study was to determine the frequency of colonization of the mother's vagina and the preterm infant's respiratory tract and to associate U.

Tissue evaluation of immune markers in endometrial and cervical carcinomas.

Major histocompatibility complex (HLA system) class II molecules including HLA-DR antigens, associate with peptides, which are derived from antigens, for presentation to T4 lymphocytes. Functional and adhesion assays have shown that CD4 molecule interacts with HLA class II molecules, leading to enhanced responses of T4 cells. In the present study, we examined the tissue expression of HLA-DR antigens and the quantitative variance of T4 lymphocytes in a series of 50 "endometrioid" adenocarcinomas of the endometrium and 35 cervical squamous-cell carcinomas.

Immunohistochemical expression was studied on paraffin-embedded tissue from the primary tumor.

Angiogenic properties of carcinoma in situ and microinvasive carcinoma of the uterine cervix.

Neovascularization is a critical step in the growth, progression and metastasis of tumors. The degree of angiogenesis may correlate with disease stage and provide prognostic information in various neoplasms. Microvessel density was studied in 24 patients with severe cervical intraepithelial neoplasias, 15 patients with microinvasive carcinomas (International Federation of Gynecology and Obstetrics IA1) and 15 healthy controls who had undergone hysterectomy for benign conditions.

A double embryo transfer on days 2 and 4 or 5 improves pregnancy outcome in patients with good embryos but repeated failures in IVF or ICSI.

The purpose of this paper was to evaluate the outcome of a double embryo transfer during the same cycle for patients who had had three or more implantation failures in IVF-ET or ICSI-ET programs after the transfer of good quality embryos in all attempts. Forty-five women who had had previous unsuccessful attempts in IVF-ET or ICSI-ET programs after transfer of good quality embryos (Group A) were included in the study.
