Live birth in a woman without ovaries after autograft of frozen-thawed ovarian tissue combined with growth factors.

Currently, cryopreservation of oocytes, embryos and ovarian tissue is considered the basis of fertility preservation programs for women with cancer and other diseases who are rendered sterile by gonadotoxic drugs or radiation.Numerous studies have confirmed that autograft of frozen-thawed ovarian tissue can restore ovarian function and fertility. A total of twenty-two live births have been reported but we still have to consider this technique as experimental.

Hysteroscopic diagnosis of a high-grade endometrial sarcoma in a 41-year-old woman.

Endometrial stromal sarcomas originate in the endometrial cavity. These tumors represent between 15-27.9% of uterine sarcomas.

Cauterization of meso-ovarian vessels, a new model of intrauterine growth restriction in rats.

Intrauterine growth restriction (IUGR) remains an important cause of perinatal morbidity and mortality. Both IUGR and low birth weight have been identified as risk factors for increased incidence of cardiovascular disease, dyslipemia, and other diseases in the adulthood. Several animal models have been developed to study the underlying mechanisms of IUGR and its later consequences, with utero-placental ischemia by uterine artery ligation (UAL) being the most frequently used in rats.

Villoglandular papillary adenocarcinoma of the uterine cervix: a case report and literature review.

Villoglandular papillary adenocarcinoma is an infrequent form of well differentiated cervical papillary adenocarcinoma that has recently been described. It usually affects young women and is distinguished from other adenocarcinomas by its generally good prognosis, since it infrequently invades the lymphovascular space. We present a case of villoglandular papillary adenocarcinoma in a 28-year-old woman presenting risk factors for developing it: use of oral contraceptives, tobacco use, and infection with human papillomavirus types 16 and 33.

Use of letrozole in assisted reproduction: a systematic review and meta-analysis.

Background: Letrozole is the third-generation aromatase inhibitor (AI) most widely used in assisted reproduction. AIs induce ovulation by inhibiting estrogen production; the consequent hypoestrogenic state increases GnRH release and pituitary follicle-stimulating hormone (FSH) synthesis.

Methods: A systematic search of the literature was performed for both prospective and retrospective studies.

Polycystic ovaries in nonobese adolescents and young women with ovarian androgen excess: relation to prenatal growth.

Objective: Reduced growth before birth is known to associate with a smaller ovarian volume in adolescents and women without androgen excess. We studied whether prenatal growth relates also to ovarian size and polycystic ovary (PCO) morphology in nonobese adolescents and young women with ovarian androgen excess.

Design: A cross-sectional analysis of standardized case notes over a 2-yr period was performed.

Long-term efficacy and tolerability of flutamide combined with oral contraception in moderate to severe hirsutism: a 12-month, double-blind, parallel clinical trial.

Objective: Our objective was to test the efficacy and tolerability of three doses of flutamide (125, 250, and 375 mg) combined with a triphasic oral contraceptive (ethynylestradiol/levonorgestrel) during 12 months to treat moderate to severe hirsutism in patients with polycystic ovary syndrome or idiopathic hirsutism.

Design: We conducted a randomized, double-blind, placebo-controlled, parallel clinical trial.

Patients: A total of 131 premenopausal women, suffering from moderate to severe hirsutism, were randomized to placebo or 125, 250, or 375 mg flutamide daily associated with a triphasic oral contraceptive pill.

Cancer of the vulva in a 25-year-old woman with VIN III and high-grade cervical SIL--case report.

Human papillomavirus (HPV) infection is associated with an increase in intraepithelial lesions of the genital tract which are often multicentric. Following is a presentation of a case of vulvar cancer in a young woman (25 years of age) with multiple vulvar intraepithelial neoplasia (VIN III) lesions, a high-grade squamous intraepithelial cervical lesion, and a HPV type 16 infection at high risk of oncogenic transformation. This case offers an opportunity to discuss the risk factors that may favor the appearance of these lesions in young women, and their clinical management, diagnosis, and treatment.

Prevalence of human papilloma virus infection of the uterine cervix in women with abnormal cervical cytology.

Purpose Of Investigation: To determine the prevalence of human papillomavirus (HPV) using polymerase chain reaction (PCR) in women with abnormal cytology results.

Methods: A prospective study of 215 women with abnormal cytology results referred consecutively to the cervical pathology clinic was carried out. A second cervical cytology using the Bethesda System was performed on all the patients to confirm the initial diagnosis, as well as to test for the presence of HPV by PCR and a colposcopy and punch biopsy in cases presenting with an abnormal pattern on colposcopy.

Hormonal environment in the induction of breast cancer in castrated rats using dimethylbenzanthracene: influence of the presence or absence of ovarian activity and of treatment with estradiol, tibolone, and raloxifene.

Objective: The influence of hormone therapy on the induction or the promotion of breast cancer has yet to be determined. Recent studies establish a cause-effect relation between hormones and cancer, although epidemiological data and studies of tumor behavior give rise to doubts. The aim of the study was to observe and evaluate the influence of different hormonal environments on the induction of breast cancer in a well-established experimental model.

Uterine adenosarcoma diagnosed following hysteroscopic resection of an intrauterine tumour.

Uterine adenosarcoma is a mixed müllerian tumour consisting of a benign epithelial component and a malignant stromal component. It is a rare tumour that represents 8% of uterine sarcomas. We present a case of a 61-year-old woman who underwent a surgical hysteroscopy for postmenopausal metrorrhagia and thickened endometrium detected by ultrasonography.

Evolution of Spanish scientific production in international obstetrics and gynecology journals during the period 1986-2002.

Objective: The present bibliometric study analyzes Spanish scientific work published in the field of obstetrics and gynecology in the most important journals during the period 1986-2002.

Study Design: The material studied (779 original documents) was selected in accordance with the science citation index (SCI) of 2001, obstetrics and gynecology section, using the EMBASE: Obstetrics and Gynecology database. We applied the customary rules of bibliometrics: Price's Law of increase in scientific literature, Bradford's Law of scattering of scientific literature and Lotka's Law of author productivity.

Insulin-sensitizing agents: use in pregnancy and as therapy in polycystic ovary syndrome.

Treatment with insulin-sensitizing agents is a relatively recent therapeutic strategy in women with polycystic ovary syndrome (PCOS) and insulin resistance. The key areas addressed in this review include PCOS and the development of type 2 diabetes mellitus and gestational diabetes, as well as the use of insulin-sensitizing agents, particularly metformin, in the management of infertility in obese and non-obese PCOS women. Treatment with metformin in PCOS women undergoing IVF and the use of metformin during gestation will be discussed.

Long-term ovarian function evaluation after autografting by implantation with fresh and frozen-thawed human ovarian tissue.

The transplantation of ovarian tissue has recently been the focus of intense investigation with the aim of avoiding premature ovarian failure mainly in patients receiving chemotherapy or radiotherapy for malignant disease. Here, we present an evaluation of the long-term function of both fresh (patients 1, 2, and 3) and cryopreserved (patient 4) ovarian autografts in four premenopausal patients aged 46-49 yr who underwent heterotopic ovarian transplantation and were followed over a 1-yr period without receiving gonadotropins to stimulate follicular growth. In patients 1 and 2, approximately 1 cm(3) ovarian cortical autograft was placed sc in the inner aspect of the arm, whereas and in patients 3 and 4 minced ovarian tissue was placed into a muscle pocket in the abdominal wall.

Acute paroxysmal dystonia induced by fluoxetine.

We report a case of a 32-year-old woman who developed paroxysmal episodes of right hemidystonia 2 days after taking fluoxetine. The attacks subsided 2 days after fluoxetine was withdrawn and did not recur afterwards. To our knowledge, this is the first report of paroxysmal dystonia induced by fluoxetine.

[Isolated sensory trigeminal neuropathy caused by a lateral pontine infarct]].

Lesion of cranial nerves due to vascular damage at pontine level generally associates affectation of near nerve tracts. Isolated fifth nerve palsy due to vascular pontine lesions has been scarcely reported. We present a hypertense 57 year old woman who suffered from sudden paresthesias and hypoesthesia on the three divisions of trigeminal nerve without motor involvement and with preservation of corneal and masseter reflexes.
