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.

Ovarian endometrial cysts: the role of gonadotropin-releasing hormone agonist and/or drainage.

Objective: To evaluate the role of GnRH agonist (GnRH-a) and/or drainage in the management of large endometriomas.

Design: This prospective clinical study was conducted in a parallel and randomized design.

Setting: Department of Gynecology, Cliniques Universitaires St.

[The role of GnRH agonists in the endoscopic treatment of endometriosis and fibromyomas].

Uterine myomas and endometriosis are benign pathologies frequently encountered in women. Myomas are often associated with infertility and/or menorrhagia particularly if they are sub-mucosal. Endometriosis is diagnosed in more than 35% of infertile patients.

Neodymium: YAG laser hysteroscopy in large submucous fibroids.

The preoperative use of a potent, subcutaneously injected gonadotropin-releasing hormone agonist (GnRH-a) was evaluated in a series of 60 women with large submucosal fibroids. Myomectomy by hysteroscopy and Nd:YAG laser was easily performed. In 12 cases, the largest portion of the myoma was not inside the uterine cavity and myomectomy was carried by a two-step hysteroscopy.

[Treatment of endometriosis. Evaluation of preoperative therapy with danazol, gestrinone and buserelin (nasal spray and implant)].

In order to adequately assess the effectiveness of danazol, gestrinone, buserelin-nasal spray (IN) and buserelin-implant (SC), a prospective non randomized study was initiated in 178 patients with laparoscopically confirmed ovarian endometriosis. After hormonal therapy, laparotomy with microsurgical resection of endometriotic cysts or laparoscopy laser was carried out. Regression (greater than 25%) of ovarian endometriosis was noted in 30, 34, 73 and 91% of cases after danazol, gestrinone and buserelin IN and buserelin SC respectively.

Treatment of uterine fibroids with implants of gonadotropin-releasing hormone agonist: assessment by hysterography.

The effect of a potent, subcutaneously injected gonadotropin-releasing hormone (GnRH analog) (Buserelin, Hoechst, Frankfurt/Main West Germany) on the size of uterine leiomyomas and the uterine cavity area was studied in a group of 20 women. In all patients except 1, the uterine cavity area calculated by hysterosalpingography was decreased, with an average decrease of 35% (from 12.0 +/- 5.
