Immunohistochemical study of the proliferation index, oestrogen receptors and progesterone receptors A and B in leiomyomata and normal myometrium during the menstrual cycle and under gonadotrophin-releasing hormone agonist therapy.

The cell proliferation-associated antigen Ki 67 and the immunohistochemical content of oestrogen receptors (ER), progesterone receptors AB (PRAB) and progesterone receptors B (PRB) were evaluated in leiomyomata and adjacent myometrium during the menstrual cycle and in leiomyomata under gonadotrophin-releasing hormone agonist (GnRHa) therapy. The proliferative status of muscular cells was measured by evaluating the percentage of nuclei staining positive for Ki 67 (proliferation index). Quantitative analysis (QH-score) was carried out using advanced stereographic computer technology to investigate ER, PRAB and PRB.

In vitro fertilization outcome according to age and follicle-stimulating hormone levels on cycle day 3.

Purpose: In a retrospective study, the prognostic factors of in vitro fertilization outcome were studied in women of 39 years of age or older, with an elevated cycle day 3 follicle-stimulating hormone (FSH) level.

Methods: Ovarian stimulation was achieved with a combination of gonadotropin-releasing hormone agonist/human menopausal gonadotropin in a short protocol. All patients underwent FSH dosage on cycle day 3 prior to stimulation.

[Endometrial evaluation prior to tamoxifen: preliminary results of a prospective study].

The objective of this study was to try to identify, by pretreatment screening, a group of patients at higher risk of developing endometrial carcinoma on tamoxifen. Between January 1993 and January 1997, 360 postmenopausal patients with breast cancer were enrolled in this prospective study. Basal screening included gynaecologic examination with a Papanicolaou smear and endovaginal sonography.

Vascular endothelial growth factor (VEGF) in endometriosis.

Angiogenesis is likely to be involved in the pathogenesis of endometriosis. According to the transplantation theory, when the exfoliated endometrium is attached to the peritoneal layer, the establishment of a new blood supply is essential for the survival of the endometrial implant and development of endometriosis. From the known angiogenic factors, vascular endothelial growth factor (VEGF) has emerged as a pivotally important regulator of normal angiogenesis and pathological neovascularization.

Rectovaginal septum adenomyotic nodules: a series of 500 cases.

Objective: Laparoscopic procedure with excision of deep fibrotic endometriotic nodules of the rectovaginal septum and histological study of the lesions.

Setting: An academic teaching hospital.

Participants: A series of 500 women undergoing laparoscopy for pelvic pain or infertility.
