Abstract
Alterations in lipid pattern and increased risk for obstetric/neonatal complications have been observed in patients with polycystic ovary syndrome (PCOS). Pregnancy leads to physiologic changes in lipoprotein metabolism, and alterations in lipid profile have been related with adverse pregnancy outcomes. Based on these considerations, the aim of the present prospective controlled clinical study was to test the hypothesis that the changes in the lipid profile in patients with PCOS during pregnancy are characteristic and potentially related to the increased risk of obstetric/neonatal complications. One hundred and fifty nonobese PCOS women and 150 age- and body mass index (BMI)-matched healthy controls were enrolled. Serum lipids, glucose, insulin, and androgens levels were serially assayed in all subjects before and throughout pregnancy. Serum low-density lipoprotein (LDL) and triglyceride (TG) concentrations were significantly (P<0.05) higher in PCOS group than in healthy controls at each assessment. Throughout pregnancy, serum LDL and TG levels increased significantly (P<0.05) in both groups, although the change from pre-pregnancy values was significantly (P<0.05) greater in PCOS patients than in healthy controls. A significant (P<0.05) relationship was observed between serum LDL and TG changes and changes in both insulin sensitivity indexes and androgen levels in PCOS patients alone. After adjusting for maternal age, pre-pregnancy BMI and lipid levels, body weight gain, and insulin-resistance markers, serum TG concentrations during pregnancy were directly and independently associated with obstetric complications in both groups, whereas serum LDL levels only in PCOS patients. We can conclude that nonobese PCOS patients had specific changes in lipid profile during pregnancy, and that the lipid pattern typical of PCOS may account for the more frequent adverse pregnancy outcomes. PCOS-related hormonal and metabolic features, such as insulin resistance and high androgen levels, may mediate this phenomenon.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) and pregnancy are conditions characterized by an increased low-grade chronic inflammation state. A higher incidence of pregnancy complications has been detected in pregnant PCOS women. OBJECTIVE The objective of the study was to test the hypothesis that the low-grade chronic inflammation state typical of PCOS patients persists during gestation and is exacerbated by pregnancy and contributes to the increased risk of obstetric/neonatal complications. DESIGN This was a prospective controlled clinical study. SETTING The study was conducted at the Academic Department of Obstetrics and Gynecology of the "Pugliese-Ciaccio" Hospital of Catanzaro (Catanzaro, Italy). PATIENTS One hundred fifty pregnant PCOS women and 150 age- and body mass index-matched healthy pregnant controls participated in the study. INTERVENTIONS INTERVENTIONS included serial clinical, biochemical, and ultrasonographic assessments before and throughout pregnancy. MAIN OUTCOME MEASURES Serum levels of white blood cell count (WBC), C-reactive protein (CRP), and ferritin were measured. RESULTS Pregnant women with PCOS had higher WBC, CRP, and ferritin levels at study entry and at all gestational ages than controls. Changes in serum WBC and ferritin levels were significantly higher in PCOS than in controls starting from the 12th week of gestation whereas those in CRP from the 20th week of gestation. By multivariable Cox proportional hazard analysis, in the PCOS group, a significant association with the risk of adverse obstetric/neonatal outcomes was found for WBC [hazard ratio (HR) 1.52, 95% confidence interval (CI) 1.31-1.64; P = .010], CRP (HR 1.19, 95% CI 1.06-1.34; P = .019), and ferritin levels (HR 1.12, 95% CI 1.03-1.26; P = .011). CONCLUSIONS In PCOS patients, the low-grade chronic inflammation persists during gestation and is exacerbated by pregnancy, and it is associated with adverse pregnancy outcomes.

Abstract
STUDY OBJECTIVE To compare single-incision mini-slings (SIMSs) and retropubic tension-free vaginal tape (r-TVT) in terms of the long-term efficacy and safety for the treatment of female stress (SUI) or mixed urinary incontinence (MUI). DESIGN Prospective multicenter cohort trial (registration number NCT00751088) (Canadian Task Force II). SETTINGS Department of Obstetrics and Gynecology, Italy. PATIENTS Two hundred-forty women with SUI/MUI. INTERVENTIONS SIMS or r-TVT. MEASUREMENTS AND MAIN RESULTS The operative time and the use of analgesic tablets were significantly (p < .001) higher and lower, respectively, in the r-TVT group versus the SIMS group. After 24 months of follow-up, no difference between the study arms was observed in terms of the complication rate (30/120 [25%] vs 19/120 [15.8%] for the r-TVT and SIMS arms, respectively; relative risk = 1.58; 95% confidence interval, 0.94-2.65; p = .083), whereas the subjective cure rate was significantly lower in the SIMS arm than in the r-TVT arm (57/103 [55.3%] vs 89/106 [84.0%] for the r-TVT and SIMS arms, respectively; relative risk = 0.66; 95% confidence interval, 0.54-0.80]; p < .001). The proportion of retreated patients for SUI/MUI was significantly higher in the SIMS arm than in the r-TVT arm (37/103 [34.9%] vs 12/106 [11.3%] for SIMS and r-TVT arm, respectively; p < .001). CONCLUSION SIMS has no advantage in terms of safety over r-TVT and was found to be less effective than r-TVT. Thus, its use in the clinical practice should be questioned.

Abstract
STUDY QUESTION Do patients with polycystic ovary syndrome (PCOS) have macroscopic and/or microscopic placental alterations? SUMMARY ANSWER The placental structure in patients with PCOS, even in those with uncomplicated pregnancy, is altered. WHAT IS KNOWN ALREADY The spectrum of pregnancy complications seems to have a common denominator: a defective trophoblast invasion and placentation. In women with PCOS, alterations in endovascular trophoblast invasion related to insulin resistance and hyperandrogenism have been observed. STUDY DESIGN, SIZE, DURATION For this prospective case-control study, 30 pregnant patients with PCOS (cases) and 60 healthy pregnant women without PCOS features (controls) were enrolled and studied until delivery. Clinical, biochemical, ultrasonographic and obstetric data were recorded. The baseline clinical and biochemical data for screening for PCOS and for inclusion/exclusion were obtained before the seventh week of gestation. At delivery, placentas were collected and detailed macroscopic and microscopic analyses were performed. PARTICIPANTS, SETTING, METHODS Cases and controls were matched for age and BMI (all <30 kg/m(2)). The matching procedure was one-to-two. Only subjects with spontaneous conception and uncomplicated pregnancies were included in the final analysis. MAIN RESULTS AND THE ROLE OF CHANCE Placental weight (P = 0.04), thickness (P = 0.02), density (P = 0.02) and volume (P = 0.01) were significantly inferior in women with, compared with those without PCOS. The placentas from patients with PCOS more frequently had an irregular shape (P = 0.03) and a higher cord coiling index (P = 0.02). Differences between cases and controls also concerned the extent of villous (P = 0.04) and intervillous (P = 0.01) spaces, the extent of fibrosis (P = 0.03), endovascular trophoblast (depth, extension and morphometry) (P < 0.05) and mitotic activity (P = 0.01). The percentage of patients with lesions [22/30 (73.3%) versus 25/60 (41.7%), respectively; P = 0.01] and the mean number of placental lesions (3.5 ± 2.1 versus 1.4 ± 1.1, respectively; P = 0.02) were higher in the PCOS than the control group. The odds ratio for placental alterations, adjusted for weight gain, was 2.8 (95% confidence interval 1.3-9.9). LIMITATIONS, REASONS FOR CAUTION The main limitation of the study was the selection of a specific PCOS sample, which is probably not representative of the PCOS phenotype as a whole. In fact, we excluded patients with PCOS who were obese and who achieved a pregnancy following the use of ovulation inductors or assisted reproduction techniques. WIDER IMPLICATIONS OF THE FINDINGS The present study is the first to demonstrate that the morphology and microscopic structure of placenta in patients with PCOS with an uncomplicated pregnancy are altered. Further studies are needed to assess a correlation of these changes with the increased risk of obstetric complications observed in some pregnancies of women with PCOS. STUDY FUNDING/COMPETING INTEREST(S) The authors declare no conflict of interest and no financial support for the research. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE Foetal exposure to high testosterone concentrations seems to be involved in the development of mammalian brain and related to pervasive developmental disorders (PDDs). The aim of the current study was to test the hypothesis that children born from hyperandrogenic women with polycystic ovary syndrome (PCOS) are at higher risk of PDDs. DESIGN Longitudinal case-control study. PATIENTS Thirty pregnant PCOS patients with hyperandrogenaemia and other 45 pregnant healthy women were followed during pregnancy. All women had a healthy baby. MEASUREMENTS Clinical evaluations and biochemical assays of the mothers during pregnancy and after delivery were performed. The children's versions of the Autism-Spectrum Quotient (AQ-C), the Empathy Quotient (EQ-C) and Systemizing Quotient (SQ-C) tests were administered. RESULTS Total AQ-C and communication scores were significantly higher for children of PCOS patients. Stratifying our population according to sex, total AQ-C, communication and attention switching subscores were significantly higher only for daughters of PCOS patients. EQ-C and SQ-C scores resulted in significantly lower and higher scores, respectively, only in daughters of PCOS patients in comparison with those of healthy non-PCOS controls. AQ-C, EQ-C and SQ-C scores, irrespective of the studied group and/or subclassification by gender, were significantly influenced by amniotic testosterone levels. CONCLUSIONS Daughters of mothers affected by hyperandrogenic PCOS seem to have a higher risk for PDDs probably due to an unbalanced prenatal exposure to high levels of testosterone.

Abstract
CONTEXT Previous experimental and clinical data suggest impaired decidual trophoblast invasion in patients with polycystic ovarian syndrome (PCOS). OBJECTIVE The objective of the study was to test the hypothesis that decidual endovascular trophoblast invasion in pregnant patients with PCOS is impaired and to clarify the potential mechanisms involved. DESIGN This was an experimental case-control study. SETTING The study was conducted at the academic Departments of Obstetrics and Gynecology and the Unit of Pathology (Italy). PATIENTS Forty-five pregnant subjects screened from a wide population of women waiting for legal pregnancy termination were included in the final analysis. Specifically, 15 pregnant patients with PCOS were enrolled as cases and another 30 age- and body mass index (BMI)-matched healthy pregnant women without any feature of PCOS were enrolled as the controls. INTERVENTION Interventions included the collection of trophoblastic and decidual tissue at the 12th week of gestation. MAIN OUTCOME MEASURES Clinical, ultrasonographic, and biochemical data as well as the histological analysis of decidual endovascular trophoblast invasion. RESULTS The rate of implantation site vessels with endovascular trophoblast invasion (ratio between total number of implantation site vessels and total number of vessels with endovascular trophoblast invasion) and the extent of endovascular trophoblast invasion (proportion between immunoreactive areas to cytokeratin 7 and to CD34) were significantly lower in patients with PCOS compared with healthy non-PCOS controls. Endovascular trophoblast invasion data were significantly and indirectly related to the markers of insulin resistance and testosterone concentrations in PCOS patients. CONCLUSIONS Pregnant patients with PCOS patients have impaired decidual trophoblast invasion. Further studies are needed to evaluate the exact mechanisms through which insulin resistance and hyperandrogenemia exert this effect.

Abstract
OBJECTIVE To test the hypothesis that the risk of persistent glucose impairment after gestational diabetes mellitus (GDM) is increased in patients with polycystic ovary syndrome (PCOS). RESEARCH DESIGN AND METHODS The prospective case-control study included 42 pregnant patients with PCOS and GDM and 84 pregnant control patients with GDM but without clinical and biochemical hyperandrogenism, polycystic ovaries, and oligo-anovulation. The case and control subjects were matched one to two for age and BMI. The glycemic profiles were studied in all subjects 6 weeks, 12 weeks, and 18 months after delivery. The incidence and the relative risk (RR) were calculated for overall persistence of an abnormal glycemic pattern and for each specific alteration, i.e., impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and diabetes mellitus (DM). RESULTS At 18 months after delivery, the incidences of IFG, IGT, and IFG-IGT were significantly (P < 0.05) higher in the cases than in the controls. At the 18-month follow-up, the RR for the composite outcome of glucose metabolism impairment in PCOS women was 3.45 (95% CI 1.82-6.58). CONCLUSIONS Patients with PCOS are at increased risk for a persistent impaired glucose metabolism after GDM.

Abstract
The study aim was to evaluate our personal experience regarding the use and the reproductive effect of metformin administration in a large population of infertile patients with polycystic ovary syndrome (PCOS) undergoing gonadotropins ovarian stimulation for in vitro fertilization (IVF). Infertile patients with PCOS undergoing gonadotropins ovarian stimulation with (metformin group, n = 191) or without (control group, n = 187) metformin and IVF were evaluated. Treatment characteristics, patients' data and reproductive outcomes were evaluated. In all cases, metformin with an immediate-release formulation was administered, and in most of cases it was given as pre- and co-treatment (74.9%) and at a dosage of 1700 mg/day (59.7%). Stimulation length and gonadotropins doses were significantly (p < 0.05) higher in metformin group than in control group. The number of dominant follicles on day of ovarian maturation triggering and peak oestradiol levels were significantly (p < 0.05) lower in metformin group than in control group. Cycle cancellation rate under metformin resulted significantly influenced by interaction with body mass index (BMI), age and basal follicle-stimulating hormone (FSH) levels. Notwithstanding, metformin use in infertile PCOS patients who receive gonadotropins for IVF is not standardized, it seems to modulate the ovarian response to stimulation. This effect may benefit or harm on the basis of ovarian reserve and patients' characteristics.

Abstract
OBJECTIVE To evaluate the effects of metformin on the ovarian response to gonadotropins given for in vitro fertilization (IVF) programs in patients with polycystic ovary syndrome (PCOS) and reduced ovarian reserve. DESIGN Prospective, parallel, randomized, double-blind, placebo-controlled clinical trial. SETTING Academic departments of obstetrics and gynecology, and a private IVF center. PATIENT(S) Primary infertile patients with PCOS older than 35 years and/or with a basal follicle-stimulating hormone (FSH) level higher than 10 IU/L who were scheduled for IVF cycles. INTERVENTION(S) Gonadotropin-releasing hormone agonist flare-up protocol and high starting doses of recombinant FSH plus metformin or placebo tablets. MAIN OUTCOME MEASURE(S) Primary end point: cancellation rate for low ovarian response. Secondary end-points: other clinical, biochemical, and reproductive data. RESULT(S) Enrollment was stopped after 88 participants had been randomized and analyzed due to an unacceptable increased risk of poor ovarian response in the metformin arm. Statistically significant differences between the metformin and placebo groups were observed in the dose of gonadotropins used, peak estradiol levels, and the number of dominant follicles, retrieved oocytes, and metaphase II oocytes. CONCLUSION(S) In patients with PCOS and reduced ovarian reserve, metformin worsened the response to gonadotropins, and its administration should be stopped before the start of controlled ovarian hyperstimulation for IVF programs.

Abstract
Background Given the high rate of pregnancy and perinatal complications recently observed in patients with polycystic ovary syndrome (PCOS) and the lack of data on the serum variations in androgens and insulin sensitivity indexes in pregnant women with PCOS, the current study was aimed to assess these changes and their potential effect on pregnancy outcomes in a population of women with PCOS. Methods Forty-five pregnant patients with ovulatory PCOS (PCOS group) and other 42 healthy pregnant women (control group) were studied assaying serum androgen levels and insulin sensitivity indexes throughout pregnancy serially, and recording obstetrical outcomes. Results Serum androgen levels and insulin resistance indexes were significantly (p < 0.05) higher in PCOS than in control group at study entry, these differences were sustained throughout pregnancy, and their changes resulted significantly (p < 0.05) different between PCOS and control group. In PCOS patients, women who had a complicated pregnancy showed serum androgen levels and insulin sensitivity indexes significantly (p < 0.05) worse in comparison to subjects without any pregnancy and/or neonatal complications. Conclusions PCOS patients have impaired changes in serum androgen levels and insulin sensitivity indexes during pregnancy. These alterations could be implicated in the pregnancy and neonatal complications frequently observed in women affected by PCOS.

Abstract
BACKGROUND Clomiphene citrate (CC) is the first-line therapy for the induction of ovulation in infertile women with polycystic ovary syndrome (PCOS), but ∼20% of patients are unresponsive. The aim of the current study was to test the hypothesis that a 6-week intervention that consisted of structured exercise training (SET) and hypocaloric diet increases the probability of ovulation after CC in overweight and obese CC-resistant PCOS patients. METHODS A cohort of 96 overweight and obese CC-resistant PCOS patients was enrolled consecutively in a three-arm randomized, parallel, controlled, assessor-blinded clinical trial. The three interventions were: SET plus hypocaloric diet for 6 weeks (Group A); 2 weeks of observation followed by one cycle of CC therapy (Group B); and SET plus hypocaloric diet for 6 weeks, with one cycle of CC after the first 2 weeks (Group C). The primary end-point was the ovulation rate. Other reproductive data, as well as anthropometric, hormonal and metabolic data, were also collected and considered as secondary end points. RESULTS After 6 weeks of SET plus hypocaloric diet, the ovulation rate was significantly (P =0.008) higher in Group C [12/32 (37.5%)] than in Groups A [4/32 (12.5%)] and B [3/32 (9.4%)] with relative risks of 3.9 [95% confidence interval (CI) 1.1-8.3; P = 0.035] and 4.0 (95% CI 1.2-12.8; P = 0.020) compared with Groups A and B, respectively. Compared with baseline, in Groups A and C, a significant improvement in clinical and biochemical androgen and insulin sensitivity indexes was observed. In the same two groups, the insulin sensitivity index was significantly (P < 0.05) better than that in Group B. CONCLUSIONS In overweight and obese CC-resistant PCOS patients, a 6-week intervention of SET and a hypocaloric diet was effective in increasing the probability of ovulation under CC treatment. The study was registered at Clinicaltrials.gov:NCT0100468.

Abstract
BACKGROUND No data regarding metformin effects on follicular fluid anti-Müllerian hormone (AMH) levels were to date available in literature. The aim of the present study was to evaluate in patients with polycystic ovary syndrome (PCOS) whether metformin administration affects serum and follicular AMH levels, and whether this is related to ovarian response to the treatment. METHODS Twenty young patients with PCOS who had received metformin were enrolled. Ten patients were anovulatory (Met-anov group), whereas the other 10 were ovulatory (Met-ov group) but had failed to conceive. Further untreated PCOS (PCOS controls, n. 10) and healthy controls (non-PCOS controls, n. 10) who were scheduled for laparoscopic surgery were enrolled. In each subjects, clinical and biochemical evaluations were performed. AMH concentrations in blood and antral follicular fluid were assayed. RESULTS In both Met-anov and Met-ov groups, and without difference between them, serum androgens and AMH, and indices of insulin resistance were significantly (p < 0.05) improved after treatment. On the other hand, significant differences (p < 0.05) between the two groups were detected with respect to the same biochemical parameters in antral follicular fluid. In the Met-anov group, no significant correlation was observed between AMH concentrations in the follicular fluid and variation in serum androgens, AMH and insulin resistance indexes; whereas in Met-ov group significant correlations were detected between AMH levels in the follicular fluid and variation in serum androgens, AMH and insulin resistance indexes. CONCLUSIONS Metformin administration in patients with PCOS exerts a differential action on the ovarian AMH levels on the basis of ovulatory response. Changes in AMH levels in antral follicular fluid during metformin treatment could be involved in the local mechanisms mediating the ovulatory restoration.

Abstract
BACKGROUND This is a prospective long-term extension study of a randomized controlled trial aimed to assess the risk-benefit ratio of an ultra-conservative fertility-sparing approach in patients with bilateral borderline ovarian tumours (BOTs). METHODS The experimental group (n = 15) was treated with an ultra-conservative surgical approach consisting of bilateral cystectomy, whereas the control group (n = 17) received a less conservative surgery consisting of oophorectomy plus controlateral cystectomy alone. All patients received a complete laparoscopic staging followed by a fertility enhancement programme. Patients who completed childbearing were treated with a non-conservative standard treatment at the first recurrence. RESULTS After a follow-up period of 128 (9 interquartile range (IQR); 115-150 range) and 132 (7 IQR; 117-152 range) months for the experimental and control groups, respectively (P = 0.25), the time to first baby-in-arm (P < 0.02) and the relative rate (RR) of baby-in-arm (8.05 [95% confidence interval (CI), 1.20-9.66; P < 0.01]) were significantly lower and higher, respectively, for the experimental compared with the control group. Although the time to first recurrence was significently (P < 0.01) shorter for the experimental group, in the regression analysis the difference did not reach the statistic significance (P = 0.14), and the RR of recurrence (1.23 [95% CI, 0.62-3.17; P = 0.41]) was not significant. Finally the number needed to treat for pregnancy was three, the number needed to harm for radical surgery was only two. CONCLUSIONS The ultra-conservative fertility-sparing approach is more effective than the standard approach in terms of reproductive outcomes, but presents a higher oncological risk.

Abstract
OBJECTIVE The purpose of this study was to compare the effectiveness of laparoscopic ovarian diathermy (LOD) vs clomiphene citrate (CC) plus metformin in infertile patients with CC-resistant polycystic ovary syndrome (PCOS). STUDY DESIGN Fifty primary infertile patients with CC-resistant PCOS were assigned randomly to receive LOD followed by a 6-month observation (group A) or 6-cycle course of CC plus metformin (group B). Reproductive and safety outcomes were analyzed. RESULTS No significant difference between 2 groups in pregnancy (15/92 women [16.3%] vs 14/107 women [13.1%]; P = .521) and live-birth (13/92 women [14.1%] vs 12/107 women [11.2%]; P = .536) rates per cycle was observed. With the use of a Cox regression analysis, patients under medical treatment, compared with patients who received surgical treatment, had a relative risk of pregnancy of 1.2 (95% confidence interval, 0.61-2.44; P = .582) and a relative risk of live-birth of 1.4 (95% confidence interval, 0.63-2.96; P = .425). CONCLUSION LOD and CC plus metformin seem to be 2 effective approaches to treat infertility in patients with CC-resistant PCOS.

Abstract
OBJECTIVE To study the impedance to blood flow through the uterine artery in pregnant women with polycystic ovary syndrome (PCOS), and to evaluate its predictive value for adverse pregnancy and perinatal outcomes in this population. DESIGN Prospective case-control study. SETTING Academic Departments of Obstetrics and Gynaecology in Italy. POPULATION Seventy-three pregnant women with ovulatory PCOS (PCOS group) and 73 age- and body mass index-matched healthy pregnant controls (control group). METHODS Serial Doppler velocimetry measurements of the uterine artery. MAIN OUTCOME MEASURES Blood flow impedance indices and pregnancy/perinatal outcomes. RESULTS A significantly (P < 0.05) higher rate of subjects with abnormal velocimetry findings was observed in the PCOS group than in the control group. In the PCOS group, the pulsatility index (PI) at first (P = 0.042) and mid-second (P = 0.039) trimesters of pregnancy, and bilateral notch at first (P = 0.025) and mid-second (P = 0.007) trimesters of pregnancy, were the strongest independent predictors of adverse outcomes. Conversely, in the control group, PI at the first trimester of pregnancy was a predictor of adverse outcomes only when combined with bilateral notch (P = 0.042), whereas at mid-second trimester of pregnancy PI (P = 0.033) and bilateral notch (P = 0.048) were independent predictors of adverse outcomes. CONCLUSIONS Uterine artery Doppler indices are more commonly altered in pregnant patients with PCOS than in controls, showing a high predictive value for abnormal pregnancy/perinatal outcomes.

Abstract
OBJECTIVE To evaluate whether the administration of metformin exerts any effects on serum homocysteine (Hcy) levels in patients with polycystic ovary syndrome (PCOS) and whether supplementation with folate enhances the positive effects of metformin on the structure and function of the vascular endothelium. RESEARCH DESIGN AND METHODS A total of 50 patients affected by PCOS, without additional metabolic or cardiovascular diseases, were enrolled in a prospective nonrandomized placebo-controlled double-blind clinical study. They were grouped into two treatment arms that were matched for age and BMI. Patients were treated with a 6-month course of metformin (1,700 mg daily) plus folic acid (400 microg daily; experimental group, n = 25) or placebo (control group, n = 25). Complete hormonal and metabolic patterns, serum Hcy, folate, vitamin B12, endothelin-1 levels, brachial artery diameter at the baseline (BAD-B) and after reactive hyperemia (BAD-RH), flow-mediated dilation, and intima-media thickness in both common carotid arteries were evaluated. RESULTS After treatment, a significant increase in serum Hcy levels was observed in the control group compared with the baseline values and the experimental group. A beneficial effect was observed in the concentrations of BAD-B, BAD-RH, flow-mediated dilation, intima-media thickness, and serum endothelin-1 in both groups. However, the results were improved more significantly in the experimental group than in the control subjects. CONCLUSIONS Metformin exerts a slight but significant deleterious effect on serum Hcy levels in patients with PCOS, and supplementation with folate is useful to increase the beneficial effect of metformin on the vascular endothelium.

Abstract
Background The significance of polycystic ovarian morphology and its relation to polycystic ovary syndrome (PCOS) is unclear, but probably it is associated with higher androgen and insulin levels and lower sex hormone binding globulin (SHBG) in absence of identifiable differences in gonadotropin dynamics. The aim of this study was to evaluate ovarian morphology in patients affected by PCOS with different ovulatory responses to metformin. Methods In this cross-sectional analysis, we studied 20 young normal-weight PCOS patients who had received a six-month course of metformin treatment. Ten of these patients remained anovulatory (anovulatory group), whereas other ten became ovulatory, but failed to conceive (ovulatory group). Other ten age- and body mass index (BMI)-matched PCOS subjects were also enrolled as controls and observed without any treatment (control group). Results After six months of metformin, in both PCOS treated groups, a similar improvement in testosterone (T) and insulin resistance indexes was observed. Moreover, in one (10.0%) and nine (90.0%) subjects from anovulatory and ovulatory PCOS groups, respectively, ovarian morphology changed, whereas a significant reduction in ovarian dimension was observed in the PCOS ovulatory group only. Conclusion PCOS patients under metformin administration demonstrate a change in ovarian morphology closely related to ovulatory response.

Abstract
BACKGROUND Lifestyle modifications are successfully employed to treat obese and overweight women with polycystic ovary syndrome (PCOS). The aims of the current pilot study were (i) to compare the efficacy on reproductive functions of a structured exercise training (SET) programme with a diet programme in obese PCOS patients and (ii) to study their clinical, hormonal and metabolic effects to elucidate potentially different mechanisms of action. METHODS Forty obese PCOS patients with anovulatory infertility underwent a SET programme (SET group, n = 20) and a hypocaloric hyperproteic diet (diet group, n = 20). Clinical, hormonal and metabolic data were assessed at baseline, and at 12- and 24-week follow-ups. Primary endpoint was cumulative pregnancy rate. RESULTS The two groups had similar demographic, anthropometric and biochemical parameters. After intervention, a significant improvement in menstrual cycles and fertility was noted in both groups, with no differences between groups. The frequency of menses and the ovulation rate were significantly (P < 0.05) higher in the SET group than in diet group but the increased cumulative pregnancy rate was not significant. Body weight, body mass index, waist circumference, insulin resistance indexes and serum levels of sex hormone-binding globulin, androstenedione and dehydroepiandrosterone sulphate changed significantly (P < 0.05) from baseline and were significantly different (P < 0.05) between the two groups. CONCLUSIONS Both SET and diet interventions improve fertility in obese PCOS patients with anovulatory infertility. We hypothesize that in both interventions an improvement in insulin sensitivity is the pivotal factor involved in the restoration of ovarian function but potentially acting through different mechanisms.

Abstract
BACKGROUND Neuroendocrine tumours are a heterogeneous group of separate clinico-pathological entities which have a common characteristic, i.e., expression of potential endocrine differentiation. In the ovary, the term "neuroendocrine" relates mainly to widely known carcinoids, but it may also be applied to rare neuroendocrine carcinomas as non-small cell type and small cell carcinomas of pulmonary type. In the literature only 11 cases of primary ovarian non-small cell neurendocrine carcinomas have been described and ten of these were associated with a surface epithelial ovarian tumour. Small cell neuroendocrine carcinoma of the ovary is a rare malignant tumour of the ovary. Advanced small cell carcinoma of the ovary is a very aggressive tumour with an overall poor prognosis and unfavourable outcome. CASE REPORT The case reported is unique in the literature because the authors describe a rare case of endometrial metastasis of a primary ovarian non-small cell neurendocrine carcinoma without any surface epithelial ovarian tumour association. The tumour invaded up to less than half of the myometrium. The first symptoms were related to endometrial metastasis as metrorrhagia and pelvic pain while the asymptomatic presence of primary ovarian carcinoma was not acknowledged with physical examination, routine biochemistry, tumour markers, blood count and traditional transvaginal greyscale ultrasound. CONCLUSION Magnetic resonance and three-dimensional (3D) ultrasonography with power Doppler are a great help in the diagnosis of ovarian localisation but only immunohistochemistry on histological material can provide a correct diagnosis. Immunohistochemistry expression of Ki67 is a useful marker of malignancy. Due to the rarity of this neoplasm, a general consensus for optimal treatment has yet to emerge. The reported biological aggressiveness of these tumours prompts combined treatment with radical surgery and adjuvant polychemotherapy.

Abstract
This study was intended to assess the effects of oral contraceptives given before treatment in infertile anovulatory patients with polycystic ovary syndrome who receive gonadotropins for controlled ovarian stimulation. Pretreatment with oral contraceptives increased the mono-ovulatory cycles, the duration of stimulation for noncanceled cycles, and the number of vials of gonadotropins used. It also reduced the number of dominant follicles and the peak E(2) levels for dominant follicles. No effect was observed in rates of cycle cancellation, pregnancy, abortion, live birth, multiple pregnancies, and ovarian hyperstimulation syndrome.

Abstract
OBJECTIVE To assess the reproductive outcomes after minilaparotomic and laparoscopic myomectomy in patients wishing to conceive. DESIGN Randomized controlled trial. SETTING Departments of obstetrics and gynecology of the universities of Catanzaro, Rome, and Florence, Italy. PATIENT(S) One hundred thirty-six women with symptomatic uterine leiomyomas or unexplained infertility. INTERVENTION(S) Laparoscopic and minilaparotomic myomectomy. MAIN OUTCOME MEASURE(S) Pregnancy, abortion, and live-birth rates. RESULT(S) Between the laparoscopic and minilaparotomic groups no difference was observed in cumulative pregnancy, live-birth, and abortion rates, whereas pregnancy and live-birth rates per cycle, and time to first pregnancy and live-birth were significantly higher in the laparoscopic than in the minilaparotomic group. Categorizing the patients according to surgical indication for myomectomy, cumulative pregnancy rate, pregnancy, and live-birth rates per cycle, and time to first pregnancy and live-birth were significantly better after laparoscopic myomectomy in symptomatic patients, whereas all reproductive outcomes were similar between the two groups in patients with unexplained infertility. CONCLUSION(S) Minilaparotomic and laparoscopic myomectomy improves in a similar manner the reproductive outcomes in patients with unexplained infertility, whereas the laparoscopic approach provides the best benefits in fertile patients with symptomatic leiomyomas.

Abstract
OBJECTIVE To compare the laparoscopic and minilaparotomic approaches for symptomatic uterine leiomyomas treatment in terms of safety and feasibility. DESIGN Randomized controlled trial. SETTING Three university departments of obstetrics and gynecology of Catanzaro, Rome, and Florence, Italy. PATIENT(S) One hundred thirty-six women wishing to conceive and candidate for myomectomy due to symptomatic uterine leiomyomas or unexplained infertility. INTERVENTION(S) Myomectomy through laparoscopic or minilaparotomic access. MAIN OUTCOME MEASURE(S) Surgical outcomes. RESULT(S) Leiomyoma enucleation and hysterotomy suturing times were significantly shorter after minilaparotomic myomectomy, whereas the degree of surgical difficulty was significantly higher for the laparoscopic myomectomy. Intraoperative blood loss, variation in hemoglobin levels, quantity of pain control drugs used postoperatively, and hospitalization were significantly lower in the laparoscopic group than in the minilaparotomic one. Our surgical outcomes were significantly influenced by specific investigational centers involved, and by leiomyoma dimensions and localizations. This last variable is the strongest predictor of surgical outcome. CONCLUSION(S) Laparoscopic and minilaparotomic approaches to myomectomy are two safe and minimally invasive surgical procedures. A careful evaluation of the dimensions and localizations of fibroids are needed to address to the right choice to the best approach.

Abstract
CONTEXT Clomiphene citrate (CC) and metformin are two effective drugs used to induce ovulation in patients with polycystic ovary syndrome (PCOS), even if it is still unclear which compound between them should be initially administered. OBJECTIVE The aim of the study was to compare in a clinical setting the efficacy of CC and metformin as first-line approaches for treating anovulation in infertile PCOS patients. DESIGN This study was a multicenter, nonrandomized, prospective, controlled study. SETTING The study was conducted at the Department of Obstetrics and Gynecology, Universities "Magna Graecia" of Catanzaro and "Federico II" of Naples, Italy. PATIENTS Patients included 80 infertile anovulatory patients with PCOS allocated in two body mass index- and age-matched groups (experimental and control groups). INTERVENTIONS Six months of 1700 mg/d metformin treatment (experimental group) or CC was administered using a traditional incremental-dose protocol (control group). In both groups, patients who ovulated under treatment continued the therapy for a total of 6 months. MAIN OUTCOME MEASURES Reproductive outcomes were measured. RESULTS Experimental and control groups were studied for a total of 204 and 169 cycles, respectively. No difference between the two groups was observed in ovulation (55.4 vs. 59.8%, respectively; P = 0.396), pregnancy (10.8 vs. 11.2%, respectively; P = 0.888), and abortion (19.5 vs. 26.3%, respectively; P = 0.530) rates. The cumulative pregnancy rate was not different between groups (62.9 vs. 48.6%, respectively; P = 0.225). CONCLUSION A 6-month course of 1700 mg/d metformin treatment and CC administered in an escalation protocol are two effective first-line approaches for improving fertility in anovulatory PCOS women.

Abstract
CONTEXT To date, the metabolic effects of the long-term metformin administration in anovulatory patients with polycystic ovary syndrome (PCOS) are known, whereas few data are available on the effects of its suspension. OBJECTIVE The objective of the study was to evaluate the effects of metformin suspension on insulin sensitivity in PCOS patients. DESIGN This was a prospective, randomized, placebo-controlled study. SETTING The study was conducted at the University "Magna Graecia" of Catanzaro, Italy. PATIENTS Patients included 30 normal-weight anovulatory PCOS women and 10 age- and body mass index-matched healthy controls. INTERVENTION PCOS patients were randomized to receive 1700 mg daily metformin (metformin group) or placebo tables (placebo group) for 12 months, whereas no treatment was administered in healthy women (control group). MAIN OUTCOME MEASURES Clinical, endocrine, and metabolic profile and clamp insulin sensitivity index were evaluated at study entry and after 6, 12, 18, and 24 months. RESULTS At baseline, the clamp insulin sensitivity index resulted significantly different (P < 0.05) in PCOS patients in comparison with healthy controls, without difference between metformin and placebo groups. During treatment, the clamp insulin sensitivity index was significantly improved (P < 0.05) in the metformin group in comparison with baseline and placebo group, without significant differences between the 6- and 12-month assessments. At 6 and 12 months after treatment suspension, in the metformin group, insulin sensitivity index significantly (P < 0.05) worsened in comparison with that observed at baseline and during treatment and with that observed in the placebo and control groups. CONCLUSION In normal-weight anovulatory PCOS patients, long-term metformin administration exerts beneficial effects on peripheral insulin sensitivity. Furthermore, this effect disappears at treatment suspension.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a common disorder associated with a wide range of endocrine and metabolic abnormalities. Low-grade chronic inflammation is a related complication recently observed in PCOS. Increased white blood cell (WBC) count was previously reported in PCOS women. OBJECTIVE To evaluate the effects of six months metformin administration on WBC count in PCOS women. PATIENTS AND METHODS Fifty normal-weight PCOS women without additional metabolic or cardiovascular diseases were enrolled and treated with metformin (850 mg twice daily) for 6 months in a prospective baseline-controlled clinical study. At baseline and after treatment, WBC count and C-reactive protein (CRP) were evaluated in each patient. The whole hormonal profile, serum insulin and glucose levels (at fasting and during a 75 g 2-h oral glucose tolerance test), serum lipid profile were also assessed. RESULTS A significant difference was observed in WBC count (7050 +/- 552 vs 6080 +/- 577 cell/mm(3) +/- s.d., P<0.001) and CRP levels (1.8 +/- 0.9 vs 1.1 +/- 0.6 mg/l +/- s.d., P<0.001) after metformin treatment in comparison with baseline values. SHBG levels and the free androgen index also changed significantly (P<0.001). Finally, high-density lipoproteins and the area under curve for glucose/area under curve for insulin ratio also significantly increased (P<0.001), whereas low-density lipoproteins and area under curve for insulin were significantly reduced (P<0.001). No other change was found in any of the biochemical parameters evaluated. CONCLUSION A six-month course of metformin reduces WBC count in PCOS women.

Abstract
STUDY OBJECTIVE To evaluate the relationship between intraabdominal visceral fat (IVF) and early conversion from laparoscopy to laparotomy in obese patients. DESIGN Prospective study (Canadian Task Force classification II-2). SETTING Department of obstetrics and gynecology, University "Magna Graecia" of Catanzaro. PATIENTS One hundred fifty-one obese patients with endometrial cancer and laparoscopic surgery. INTERVENTIONS Laparoscopic treatment for early-stage endometrial cancer. MEASUREMENT AND MAIN RESULTS In all patients, demographic, anthropometric (including body mass index, waist-to-hip ratio, and waist circumference), and IVF assessments (using ultrasonography [IVF-USG, cm] and computed tomography [IVF-CT, cm(2)]), were evaluated. In 122 patients (122/151, 80.8%), the laparoscopies were successfully completed (group A), whereas 29 patients (29/151, 19.2%) had a laparotomic conversion. Specifically, in 19 (19/29, 65.5%) and in 10 patients (10/29, 34.5%) the conversion was early (group B1) and late (group B2), respectively. A significant (p <.05) difference in surgical stage IC and in postoperative complications rate was detected between group A and groups B1 and B2, without difference between these 2 last groups. IVF-USG and IVF-CT were significantly (p <.01) higher in group B1 in comparison with groups A and B2, without difference between these 2 last groups. A strong and significant (p <.001) association between IVF-USG and IVF-CT was detected in all groups by Spearman bivariate correlation (r = 0.78, 0.918, and 0.978 for group A, B1, and B2, respectively). Multivariate analysis showed the IVF-CT as the main predictor for early laparotomic conversion (OR 2.184; 95% CI 1.227-3.886). CONCLUSIONS Intraabdominal visceral fat is a predictor for early laparotomic conversion in obese patients with endometrial cancer. Further studies are necessary to assess the efficacy of the IVF evaluation for reducing the laparotomic conversion risk in obese women undergoing laparoscopic surgery for gynecologic malignancy.

Abstract
Pelvic pain associated with endometriosis is a common clinical problem. In approximately 20% of cases endometriosis-related pelvic pain is either minimally or not responsive to medical treatment; thus surgical treatment seems to be a valid option. The aim of this review is to describe presacral neurectomy surgical techniques, data regarding safety and efficacy of this procedure, its indications, and future research on its applications in clinical practice.

Abstract
BACKGROUND During the childbearing years, the standard fertility-sparing treatment for bilateral borderline ovarian tumours (BOTs) is the unilateral oophorectomy plus controlateral cystectomy. The aim of the present study was to compare the effects of two laparoscopic fertility-sparing surgical procedures for the treatment of bilateral BOTs on recurrence and fertility in young women who desire to conceive as soon as possible. METHODS Thirty-two women affected by bilateral early-stage BOTs who desired to conceive were randomized to receive bilateral cystectomy (experimental group, n=15) or oophorectomy plus controlateral cystectomy (control group, n=17). At the first recurrence after childbearing completion, each patient was treated with non-conservative standard treatment. Recurrences and reproductive events were recorded. RESULTS After a follow-up period of 81 months (19 inter-quartile; 60-96 range), the cumulative pregnancy rate (CPR) (14/15 versus 9/17; P=0.003) and the cumulative probability of first pregnancy (P= 0.011) were significantly higher in the experimental than in control group. No significant (P=0.358) difference between groups was detected in cumulative probability of first recurrence. CONCLUSIONS The laparoscopic bilateral cystectomy followed by non-conservative treatment performed at the first recurrence after the childbearing completion is an effective surgical strategy for patients with bilateral early-stage BOTs who desire to conceive as soon as possible.

Abstract
CONTEXT Insulin resistance is a feature of polycystic ovary syndrome (PCOS), and it is related to mitochondrial function, particularly with maximal oxygen consumption (VO(2max)). At the moment, no evaluation of cardiopulmonary functional capacity in young patients with PCOS has been performed. OBJECTIVE Our objective was to assess cardiopulmonary functional capacity in young PCOS overweight patients. DESIGN AND SETTING We conducted a prospective baseline-controlled clinical study at University Federico II of Naples, School of Medicine (Naples, Italy). PATIENTS Forty-five PCOS patients were matched with 45 healthy women for age (mean +/- sd, 21.3 +/- 2.0 vs. 21.6 +/- 1.9 yr, respectively) and body mass index (29.4 +/- 3.6 vs. 29.0 +/- 3.4 kg/m(2), respectively). MEAN OUTCOME MEASURES We assessed hormonal and metabolic pattern and functional capacity by cardiopulmonary exercise testing to evaluate maximal oxygen consumption (VO(2max)), oxygen consumption at anaerobic threshold (VO(2AT)), and the maximal workload at peak exercise. RESULTS VO(2max) (17.0 +/- 3.7 vs. 26.8 +/- 3.5 ml/kg.min), oxygen consumption at anaerobic threshold (13.9 +/- 3.0 vs. 21.2 +/- 3.8 ml/kg.min), and maximal workload at peak exercise (101.3 +/- 25.2 vs. 135 +/- 22.6 W) were significantly (P < 0.001) reduced in PCOS subjects compared with healthy women. The multiple linear regression analysis showed that only homeostasis model assessment appears to have a strong negative linear relation with VO(2max) in PCOS. No relation was found in controls. CONCLUSIONS Our data demonstrate a reduced cardiopulmonary functional capacity in young PCOS patients.

Abstract
BACKGROUND Previous data on the efficacy of clomiphene citrate, the most commonly used drug for treating anovulatory infertility in patients with polycystic ovary syndrome (PCOS), have shown a discrepancy between ovulation and pregnancy rates. In the present subanalysis (of a larger previously published randomized controlled trial), the effect of clomiphene citrate on several ultrasonographic markers of uterine receptivity in PCOS patients who ovulated under treatment was studied. METHODS Thirty-three PCOS women who ovulated under 150 mg daily clomiphene citrate and 33 healthy controls were studied. Uterine, subendometrial and endometrial blood flows, endometrial thickness and pattern were assessed using serial ultrasonographic assessments. The data were analysed before and after grouping the clomiphene citrate-stimulated ovulatory cycles for reproductive outcome [unfavourable (ovulation alone or early pregnancy loss) or favourable outcome (clinical pregnancy and/or live birth)]. RESULTS Both before and during treatment, uterine vascularity assessed at all sites was significantly lower in the PCOS group than in controls. Endometrial thickness and pattern were impaired in the PCOS group under clomiphene citrate treatment. A significant difference in all ultrasonographic parameters was observed between cycles ending in unfavourable versus those ended in favourable outcome. CONCLUSIONS Clomiphene citrate administration alters several surrogate ultrasonographic parameters of uterine receptivity, and this effect could be crucial for its efficacy.

Abstract
BACKGROUND Laparoscopic ovarian diathermy (LOD) has been used successfully as a first-, second- and third-line treatment for ovulation induction in women with polycystic ovary syndrome (PCOS). However, little is known about the predictors for LOD efficacy. The aim of the present study was to evaluate reproductive outcomes in clomiphene citrate (CC)-resistant PCOS patients treated with LOD according to ovarian and chronological age. METHOD A total of 60 non-obese, primary infertile, CC-resistant women with PCOS were enrolled and treated with LOD. During the following 6 months, all patients underwent ovulation monitoring and timed intercourse. If spontaneous ovulation did not occur within 3 months from surgery, CC (100 mg/day) was administered for 5 days from day 3 of the remaining cycles. The ovulation, abortion and pregnancy rates were assessed and analyzed with patients categorized according to chronological age (group A, <25 years; group B, 25-30 years; group C, 30-35 years; group D, >35 years) and ovarian age (group 1, follicle stimulating hormone (FSH) < 10 mIU/ml; group 2, FSH > 10 mIU/ml). RESULTS At the end of the study, total ovulation, pregnancy and abortion rates were 57.1, 13.0 and 18.2%, respectively. No difference in all reproductive outcomes was observed between groups A, B and C, whereas the efficacy of LOD was significantly lower in group D. A significant difference in all clinical endpoints was detected between groups 1 and 2. CONCLUSIONS Our data show that chronological age >35 years and basal FSH value > 10 mIU/ml are related to poor reproductive prognosis in CC-resistant PCOS patients treated with LOD.

Abstract
OBJECTIVE To assess and compare the laparoscopic uterine nerve ablation (LUNA) and the vaginal uterosacral ligament resection (VUSR) in postmenopausal women with chronic pelvic pain (CPP). STUDY DESIGN Eighty postmenopausal women with intractable and severe midline CPP were randomized to undergo LUNA or VUSR. Costs of two surgical procedures were assesses. Cure rate, severity of CPP, and deep dyspareunia were also evaluated after 6 and 12 months from surgery. RESULTS The mean cost of LUNA resulted significantly higher in comparison with VURS (2078+/-637 versus 1497+/-297, P<0.001). The cure rate was not significantly different between the two groups at 6 (33/40, 82.5% versus 35/40, 87.5% for groups A and B, respectively; P=0.530; RR 0.94, 95% CI 0.78-1.13), and 12 months (27/36, 75.0% versus 28/38, 73.7%, for groups A and B, respectively; P=0.901; RR 0.90, 95% CI 0.78-1.33) of follow-up. At same times, a significant (P<0.01) decrease in severity of CPP and deep dyspareunia was observed in both groups with no difference between them. CONCLUSIONS Both LUNA and VUSR are equally effective surgical treatments in postmenopausal women with central CPP but VUNR is significantly cheaper than LUNA.

Abstract
In women with polycystic ovary syndrome, metformin administration, not laparoscopic ovarian drilling, reduces plasminogen activator inhibitor 1 (PAI-1) activity. The lack of a decrease in PAI-1 activity is related to a high risk for miscarriage.

Abstract
BACKGROUND In Italy, a recent law has imposed a ban on the fertilization of more than three oocytes at one time, and all resulting embryos produced must be transferred simultaneously. The aim of the present controlled study was to assess the clinical feasibility and efficacy of the perifollicular vascularity assessment for oocyte selection in IVF cycles. METHODS Fifty-four young primary infertile non-obese women (27 cases and 27 age- and BMI-matched controls) underwent IVF cycles. The choice of the oocytes to fertilize was performed according to perifollicular vascularization in the experimental group, whereas in the control group, the standard morphologic criteria alone were used. The dose of gonadotrophins used, the dominant follicles obtained, the duration of the ovarian stimulation, the number of oocytes retrieved, the number/quality of oocytes fertilized and of cleaved embryos, cycle cancellation, implantation, clinical pregnancy, ongoing pregnancy, multiple pregnancies and ovarian hyperstimulation syndrome rates were assessed in each group. RESULTS The assessment of perifollicular vascularity was feasible in 88.9% of cases. No difference between groups was detected in any parameter evaluated. CONCLUSION Power Doppler assessment of perifollicular vascularity seems to have no clinical utility for oocyte selection in IVF cycles for young infertile women.

Abstract
OBJECTIVE To compare the efficacy of clomiphene citrate (CC) administration for ovulation induction in CC-resistant oligo-ovulatory women with polycystic ovary syndrome (PCOS) after metformin treatment or laparoscopic ovarian drilling (LOD). Design Prospective controlled study. PATIENTS Twenty-eight overweight oligo-amenorrhoeic women with PCOS who were still anovulatory after metformin administration (group A, n = 8) or LOD (group B, n = 20). METHODS Treatment with CC 150 mg/day for 5 days from the third to the seventh day of a progesterone-induced uterine bleeding for 6 months. MEASUREMENTS The ovulation, pregnancy, abortion and live-birth rates were evaluated in each group. RESULTS The subjects of groups A and B were studied for a total of 36 and 74 cycles, respectively. At the end of the study, no differences in ovulation [11/36 (30.6%) vs. 23/74 (31.1%); P = 0.96], pregnancy [6/36 (16.7%) vs. 12/74 (16.2%); P = 0.95], abortion [2/6 (33.3%) vs. 5/12 (41.7%); P = 1.00] and the live-birth [4/6 (66.7%) vs. 7/12 (58.3%); P = 1.00] rates were observed between groups A and B. CONCLUSION Metformin administration as well as LOD improves the effectiveness of CC for ovulation induction in overweight infertile CC-resistant women with PCOS.

Abstract
CONTEXT Recent data indicate that women affected by the polycystic ovary syndrome (PCOS) are at greater risk for cardiovascular disease and that metformin may improve the metabolic alterations in these patients. OBJECTIVE The objective of this study was to evaluate the effects of 6 months of metformin administration on endothelial structure and function in women with PCOS. DESIGN This was a prospective, baseline-controlled, clinical study. SETTING The study was performed at University Federico II (Naples, Italy). PATIENTS Thirty young normal-weight women with PCOS without additional metabolic or cardiovascular diseases were studied. INTERVENTIONS Metformin (850 mg daily) was administered for 6 months. MEAN OUTCOME MEASURES The main outcome measures were complete hormonal profile, including total testosterone, SHBG, dehydroepiandrosterone sulfate, prolactin, and gonadotropin levels; serum insulin and glucose levels during a 75-g 2-h oral glucose tolerance test; plasma endothelin-1 concentrations (picomoles per liter +/- sd); serum lipid profile; brachial artery baseline diameter (millimeters +/- sd), diameter after reactive hyperemia (millimeters +/- sd), and flow-mediated dilation (percentage +/- sd); and the intima media thickness (millimeters +/- sd) on both common carotid arteries. RESULTS After treatment, SHBG levels and the free androgen index changed significantly (P < 0.001). High-density lipoproteins and the area under curve for glucose/area under curve for insulin ratio also significantly (P < 0.001) increased, whereas low-density lipoproteins and plasma endothelin-1 levels were significantly (P < 0.001) reduced. No other change was found in any of the biochemical parameters evaluated. A significant difference was observed in brachial artery baseline diameter (3.24 +/- 0.30 vs. 3.0 +/- 0.30), flow-mediated dilation (14.30 +/- 1.90 vs. 15.70 +/- 1.50) (P < 0.01, each), diameter after reactive hyperemia (3.70 +/- 0.30 vs. 3.55 +/- 0.10) (P < 0.05), and intima media thickness (0.53 +/- 0.09 vs. 0.40 +/- 0.07) (P < 0.001) after metformin treatment in comparison with baseline values. CONCLUSIONS A 6-month course of metformin improves endothelial structure and function in young, normal-weight women with PCOS.

Abstract
BACKGROUND Metformin has been shown to improve fertility in anovulatory patients with polycystic ovary syndrome (PCOS), inducing not only a high ovulation and pregnancy rate but also reducing the incidence of miscarriages. The aim of the present study was to evaluate the uterine effects of metformin in patients with PCOS who ovulated under metformin. METHODS Thirty-seven non-obese primary infertile anovulatory patients with PCOS and another 30 age- and body mass index-matched healthy women (control group) were studied. PCOS patients were treated with metformin (850 mg twice daily) for 6 months, whereas the control group did not receive any treatment. In these PCOS patients who ovulated whilst under metformin treatment (PCOS group) and in controls, uterine, sub-endometrial and endometrial blood flow, and endometrial thickness and pattern were evaluated using serial ultrasonographic assessments. RESULTS Before treatment, uterine, sub-endometrial and endometrial blood flows were significantly lower in patients with PCOS than in the control group. All indexes of uterine vascularization were significantly improved in the PCOS group with metformin treatment and were not different from the controls. Nor was any difference in endometrial thickness and pattern detected between PCOS and control groups. After grouping the data of PCOS patients who ovulated under metformin for cycles with favourable/unfavourable reproductive outcome, no difference in any parameter was observed. CONCLUSIONS Metformin improves all surrogate markers of endometrial receptivity in PCOS patients, without difference between patients who had favourable or unfavourable reproductive outcome.

Abstract
OBJECTIVE This study was undertaken to compare the quality of life (QoL) in women with early stage endometrial cancer treated with 2 different surgical approaches. STUDY DESIGN Eighty-four women with clinical stage I endometrial cancer were enrolled in a prospective randomized controlled trial design and treated with laparoscopic or laparotomic approach. Another 40 women matched for demographic characteristics were studied as controls. In patients, before and after surgery, and in their matched controls, QoL was evaluated by using the Short-Form Healthy Survey (SF-36) and the climacteric symptoms using the Kupperman Index (KI). RESULTS After randomization, no difference was detected in data recorded between the groups. At entry, QoL was similar in both treatment groups but significantly (P < .05) worse in comparison with controls. Throughout the study, QoL was significantly (P < .05) higher in laparoscopic group versus laparotomic group. After KI adjustment our data did not change. CONCLUSION In early stage endometrial cancer, the laparoscopic approach provides significant benefits compared with laparotomy in terms of QoL.

Abstract
Patients with inflammatory bowel disease (IBD) have frequently a bone mineral density (BMD) significantly lower than age-matched healthy subjects. The low BMD observed in IBD patients is related also to a higher incidence of bone fractures. In this prospective randomized study we evaluated the effect of 1-year risedronate administration on bone mass and turnover, and on vertebral fractures in osteoporotic postmenopausal women with IBD in remission. Ninety osteoporotic postmenopausal women were randomized to receive oral risedronate 35 mg/week (risedronate group) or placebo tablets (placebo group; one tab/week). The duration of treatment was 12 months. At entry and after treatment, lumbar spine and hip BMD, and serum osteocalcin (OC) and urinary deoxypyridinoline/creatinine ratio (DPD-Cr) levels were evaluated. Vertebral fractures were assessed from thoracic and lumbar lateral and anterior-posterior spinal radiographs taken at baseline, and from lateral spinal radiographs taken at the end of the study. At study entry, no difference between groups was also detected in BMD and in bone turnover markers. At the end of the study, lumbar spine, trochanter and femoral neck BMD was significantly ( p <0.05) higher in comparison with baseline in the risedronate group, whereas a significant ( p <0.05) decrease was observed in the placebo group. For the same visit, a significant ( p <0.05) difference in lumbar spine, trochanter and femoral neck BMD was detected between groups. After 12-month follow-up, serum OC and urinary DPD-Cr levels were significantly ( p <0.05) lower and higher in comparison with basal values in risedronate and placebo group, respectively. At the same time, a significant ( p <0.05) difference in serum OC and urinary DPD-Cr levels was observed between groups. Throughout the study, the incidence of vertebral fractures was significantly ( p <0.05) lower in the risedronate group than in the placebo group (12.5% vs 34.1%). The relative risk (RR) to develop a new vertebral fracture after 1 year of risedronate administration was of 0.36 (95% confidence interval, 0.14-0.85). In conclusion, risedronate administration is an effective anti-osteoporotic treatment in osteoporotic postmenopausal women with IBD in remission.

Abstract
Vitamin D receptor (VDR) gene polymorphisms could be considered one of the factors influencing the efficacy of the anti-osteoporotic treatments. In this multicenter, prospective, randomized and controlled trial we evaluated whether BsmI vitamin D receptor (VDR) genotypes influence the efficacy of antiresorptive treatment regimes (administered alone or in combination) in postmenopausal osteoporotic women. Using restriction endonuclease, we identified the BsmI VDR polymorphism in 1,100 postmenopausal women with osteoporosis. The women were randomized, taking account of genotype, into five treatment groups: (1) alendronate (Aln, 10 mg/day) plus raloxifene (Rlx, 60 mg/day); (2) Aln plus hormone replacement therapy (HRT, 0.625 mg/day conjugated equine estrogens plus 2.5 mg/day medroxyprogesterone acetate); (3) Aln alone; (4) HRT alone; and (5) Rlx alone. Lumbar-spine bone mineral density (BMD) and bone turnover markers were measured at study entry and after 1 year of treatment. Using the general linear model (GLM) repeated-measures procedure, the means of BMD and bone turnover markers significantly differed from baseline after a period of treatment. In particular, the mean change from baseline for BMD was -0.034 (95% confidence interval [CI]: -0.037 to -0.031, P <0.001); for serum osteocalcin (OC) it was 1.369 (95% CI: 1.289 to 1.448, P <0.001); and for urinary deoxypyridinoline (DPD) it was 1.322 (95% CI: 1.242 to 1.401, P <0.001), indicating a considerable variation before and after treatment of these indicators. In all three cases these effects appeared significantly influenced by treatments, genotypes, and the treatments*genotypes interaction term (P <0.001 each, except for the BMD and genotype effect with P =0.02), and not by the investigational centers involved in the study. In conclusion, in postmenopausal osteoporotic women, BsmI VDR genotypes influence the efficacy of antiresorptive drugs particularly when used in combination.

Abstract
CONTEXT Although metformin has been shown to be effective in the treatment of anovulation in women with polycystic ovary syndrome (PCOS), clomiphene citrate (CC) is still considered to be the first-line drug to induce ovulation in these patients. OBJECTIVE The goal of this study was to compare the effectiveness of metformin and CC administration as a first-line treatment in anovulatory women with PCOS. DESIGN We describe a prospective parallel randomized, double-blind, double-dummy controlled clinical trial. SETTING The study was conducted at the University "Magna Graecia" of Catanzaro, Catanzaro, Italy. PATIENTS One hundred nonobese primary infertile anovulatory women with PCOS participated. INTERVENTIONS We administered metformin cloridrate (850 mg twice daily) plus placebo (group A) or placebo plus CC (150 mg for 5 d from the third day of a progesterone withdrawal bleeding) (group B) for 6 months each. MEAN OUTCOME MEASURES The main outcome measures were ovulation, pregnancy, abortion, and live-birth rates. RESULTS The subjects of groups A (n = 45) and B (n = 47) were studied for a total of 205 and 221 cycles, respectively. The ovulation rate was not statistically different between either treatment group (62.9 vs. 67.0%, P = 0.38), whereas the pregnancy rate was significantly higher in group A than group B (15.1 vs. 7.2%, P = 0.009). The difference found between groups A and B regarding the abortion rate was significant (9.7 vs. 37.5%, P = 0.045), whereas a positive trend was observed for the live-birth rate (83.9 vs. 56.3%, P = 0.07). The cumulative pregnancy rate was significantly higher in group A than group B (68.9 vs. 34.0%, P < 0.001). CONCLUSIONS Six-month metformin administration is significantly more effective than six-cycle CC treatment in improving fertility in anovulatory nonobese PCOS women.

Abstract
OBJECTIVE To study the cell effects of raloxifene on uterine and leiomyoma tissue in postmenopausal women. DESIGN Prospective, randomized, double-blind, placebo-controlled study. SETTING Department of Obstetrics and Gynecology, University "Magna Graecia" of Catanzaro, Italy. PATIENT(S) Forty postmenopausal women affected by uterine leiomyomas and selected for hysterectomy. INTERVENTION(S) Treatment for three cycles of 28 days with raloxifene at a dose of 180 mg/day orally (raloxifene group) or placebo tablets (3 tablets/day orally) (placebo group). MAIN OUTCOME MEASURE(S) Uterine and leiomyoma dimensions were measured in each subject at entry and before surgery. On leiomyomas and homologous myometrium the proliferating cell nuclear antigen (PCNA)-positive cells/total cells (PCNA/TC) and the Bcl-2-positive cells/Bax-positive cells (Bcl-2/Bax) ratios (%), as proliferation and apoptotic indexes, respectively, were measured. RESULT(S) After treatment, uterine and leiomyoma sizes were significantly changed in comparison with baseline and the placebo group. PCNA/TC and Bcl-2/Bax ratios were significantly higher in leiomyomas than in homologous myometrium. A significant difference was detected in PCNA/TC between the myometrium of the raloxifene and control groups, whereas no difference was observed in the Bcl-2/Bax ratio. A significant difference in PCNA/TC and Bcl-2/Bax ratios was detected in leiomyoma tissue between the raloxifene group and controls. CONCLUSION(S) In postmenopausal women, raloxifene administration reduces uterine leiomyomas by exerting a cell antiproliferative and proapoptotic action.

Abstract
BACKGROUND There are few data in the literature regarding the utility of metfomin before and during gonadotrophin administration in women with polycystic ovary syndrome (PCOS). The aim of the present study was to assess the effect of the pre-treatment and co-administration of metformin in infertile PCOS women treated with controlled ovarian stimulation (COS) followed by timed intercourse (TI) or intrauterine insemination (IUI). METHODS Seventy insulin-resistant primary infertile women with PCOS were randomized to receive metformin cloridrate (850 mg twice daily; group A) or placebo tablets (two tablets daily; group B) for 3 months. Three trials of COS using highly purified urinary FSH (hpFSH) plus TI/IUI were performed. Number of ampoules of gonadotrophin used, duration of the ovarian stimulation, cycle cancellation, ovulation, pregnancy, abortion, live birth, mono-ovulatory cycles, multiple pregnancies and ovarian hyperstimulation syndrome (OHSS) rates were assessed. RESULTS No difference between groups was detected in ovulation, cycle cancellation, pregnancy, abortion, live birth, multiple pregnancies and OHSS rates. The mono-ovulatory cycle rates were significantly (P = 0.002) more frequent in group A than in group B, whereas the days of stimulation for non-cancelled cycles and the number of vials of gonadotrophins used were significantly (P < 0.001) higher in group A than in group B. CONCLUSION In insulin-resistant women with PCOS, metformin pre-treatment and co-administration with hpFSH increases the mono-ovulatory cycles.

Abstract
In women with polycystic ovary syndrome (PCOS) weight loss is associated with an improvement in insulin sensitivity and a reduction of the insulin concentration in the plasma. It is clear, then, that the first therapeutic approach that can be considered in obese PCOS patients for restoration of the menstrual cycle should be a diet. The aim of our study was to examine the effect of long-term caloric restriction on the clinical and biochemical abnormalities in obese PCOS women. The results obtained make it clear that caloric restriction for 4 weeks causes an increase in SHBG and decreases of free testosterone and insulin, with consequent improvement of the clinical picture.
