Novasure impedance control system versus microwave endometrial ablation for the treatment of dysfunctional uterine bleeding: a double-blind, randomized controlled trial.

PURPOSE OF INVESTIGATION: To compare the efficacy and safety of two different second-generation ablation devices, Novasure impedance control system and microwave endometrial ablation (MEA), in cases of abnormal uterine bleeding (AUB). MATERIALS AND METHODS: This is a randomized controlled trial that took place in a single Gynecological Department of a University Hospital. Sixty-six women with dysfunctional uterine bleeding (DUB), unresponsive to medical treatment, were included in the trial. The ratio of women allocated to bipolar radio-frequency ablation or MEA was 1:1. Follow-up assessments were carried out at three and 12 months post-ablation. The present main outcome measure was amenorrhea rates 12-months post-treatment. RESULTS: The rate of amenorrhea at 12-months post-ablation was significantly higher in women treated by Novasure (25/33; 75.8%) as compared to those treated by MEA (8/33; 24.2%) (rate difference: +51.5%, 95% CI: +27.8 to +67.7). CONCLUSION: In women with DUB, endometrial ablation with Novasure bipolar radiofrequency impedance-controlled system is associated with increased rates of amenorrhea at 12-months post-treatment as compared to the MEA method.

Laparoscopic management of unexpected borderline ovarian tumors in women of reproductive age.

PURPOSE OF INVESTIGATION: The aim of this study was to review the clinical features of women with unexpected borderline ovarian tumours. METHODS: Between October 1992 and December 2010, 1332 out of 4016 laparoscopies were performed for adnexal masses in women of reproductive age and 1838 cysts were removed. When ultrasonographic findings did not meet the criteria for low risk malignancy, tumour markers, colour Doppler and MRI/CT were applied. At laparoscopy any solid component or papilla was sent for rapid frozen section. RESULTS: Borderline ovarian tumours were found in eight (0.6%) out of 1332 patients, two of which were bilateral. The mean age was 28.75 +/- 9.27 years and the mean diameter of the cysts was 5.1 +/- 1.7 cm. In two cases unexpected malignancy was discovered during the diagnostic and in six cases during the operative phase of the intervention. CONCLUSION(S): Risk of failure to diagnose cancer could be minimised with careful patient selection preoperatively. Adequate training on laparoscopic oncology is the necessary prerequisite for a safe laparoscopic approach.

Human placental lactogen and color Doppler in predicting expulsion of retained adherent placenta: a new clinical observation.

PURPOSE: To present a new clinical observation made in three cases of retained adherent placenta, a rare obstetrical complication, associated with potentially life-threatening hemorrhage. METHODS: Three consecutive cases of retained adherent placenta are presented. RESULTS: Diagnosis of placenta increta in two and placenta percreta in one case was established with ultrasound and MRI. Methotrexate 50 mg i.v. (300 mg total dose) and follinic acid 0.1 mg/kg were administered on alternating days, over 12 days. On follow-up, placental perfusion on color Doppler was present up to the point when circulating hPL levels were no longer detectable; this was followed in all cases by spontaneous placental expulsion within 10 days. CONCLUSIONS: The observation that both color Doppler and human placental lactogen can be used to monitor response to therapy and predict placental expulsion should be evaluated in future cases of retained adherent placenta.

Mucocele of the appendix mimicking an adnexal mass: a case report.

Mucocele of the appendix is a rare entity usually mimicking an adnexal tumour. There is no specific imaging or screening method to determine the diagnosis with certainty preoperatively. Appendiceal malignancy can be the underlying cause, although it is not common. We present a case of an appendiceal mucocele mimicking an ovarian tumour by both clinical and imaging (TVS and MRI) methods. This pathological condition should be considered by all the gynaecologists in the differential diagnosis of a right-sided pelvic mass.

Galanin in the amniotic fluid and neonatal birth weight: a prospective observational study.

OBJECTIVE: The aim of the present study was to examine whether an association is present between amniotic fluid (AF) galanin and neonatal birth weight (NBW). DESIGN: Prospective observational study. SETTING: Fetal maternal unit in a tertiary teaching hospital. POPULATION: Fifty women of singleton pregnancy who underwent amniocentesis during the second trimester and delivered after the 37th week of gestation. METHODS: Amniocentesis 18th-19th gestational week for genetic indication with the use of a 22G needle under real-time sonographic guidance and measurement of galanin concentration in the AF. MAIN OUTCOME MEASURES: Association between concentration of AF galanin and NBW at term. RESULTS: Galanin was isolated in all samples of AF (median concentration 19.95 pg/mL; range: 19.0-21.7). A strong linear correlation between AF galanin and NBW was detected (τ = 0.928; p < 0.001). Non-parametric linear regression analysis revealed that galanin concentration could explain 72.1% of the variance in the NBW, when controlling for gestational week at birth and mother's body mass index at delivery. CONCLUSIONS: AF galanin during the second trimester seems to have a strong linear correlation with NBW of term deliveries in singleton pregnancies, even when controlling for important confounders.
