Abstract
The production of stable cluster arrays on smooth surfaces has several potential technological applications. We report a study of the pinning of size-selected palladium nanoclusters on the graphite surface. The clusters formed during gas aggregation in vacuum are projected with sufficient kinetic energy to create a defect in the graphite surface. The energy necessary to create such an immobilizing defect is investigated as a function of the palladium cluster size. The palladium pinning energy is found to deviate from the simple binary collision model as appropriate to previously reported silver and gold results. This finding is in agreement with the deviation of nickel clusters and points to the influence of the interatomic cluster bonding on the mechanics of the collision.

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
We report on the immobilization of the firefly protein luciferase on the hydrophobic surface of graphite. Observation by liquid-phase atomic force microscopy of islands with a height consistent with the size of a single molecule confirmed that the protein was contained within a monomolecular layer. The enzyme activity was assayed by single-photon counting of the bioluminescence, which is the catalytic product of luciferase. Attachment to the surface modified the efficiency of the enzyme, but the introduction of the substrates luciferin and ATP resulted in the reactivation of the enzyme. The functionalized graphite surface was employed as a cathode in a bioelectrochemical cell. This demonstrated that the electric field caused a substantial loss of enzyme catalytic activity.

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
PURPOSE Polycystic ovary syndrome (PCOS) is an extremely prevalent disorder in which elevated blood markers of cardiovascular risk and altered endothelial function have been found. This study was designed to determine if abnormal carotid intima-media thickness (IMT) and brachial flow-mediated dilation (FMD) in young women with PCOS may be explained by insulin resistance and elevated adipocytokines. METHODS A prospective study in 50 young women with PCOS (age: 25.2 +/- 1 years; body mass index [BMI]: 28.7 +/- 0.8) and 50 matched ovulatory controls (age: 25.1 +/- 0.7 years; BMI: 28.5 +/- 0.5) was performed. Carotid IMT, brachial FMD, and blood for fasting glucose, insulin, leptin, adiponectin and resistin were measured. RESULTS PCOS, IMT was increased (P <.01), FMD was decreased (P <.01), fasting insulin was increased (P <.01), QUICKI (a marker of insulin resistance) was decreased (P <.01), and adiponectin was lower (P <.05), whereas leptin and resistin were not different compared with matched controls. Whereas BMI or waist/hip ratios did not correlate with IMT or FMD, insulin and QUICKI correlated positively and negatively with IMT (P <.01). There was a significant negative correlation between adiponectin and IMT (P <.05). These correlations were unchanged when adjusting for BMI and the correlation between IMT and adiponectin was unaffected by insulin resistance parameters. CONCLUSIONS These data suggest that young women with PCOS have evidence for altered endothelial function. Adverse endothelial parameters were correlated with insulin resistance and lower adiponectin. Both insulin resistance and adiponectin appear to be important parameters. It is hypothesized that the type of fat distribution may influence these factors.

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
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.

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
OBJECTIVE To determine how common polycystic ovarian morphology may be in women given the clinical diagnosis of polycystic ovary syndrome (PCOS) based on chronic anovulation and hyperandrogenism and whether certain hormonal factors correlate with ovarian morphology and blood flow. DESIGN Prospective study. SETTING Two academic endocrinology centers in Italy. PATIENT(S) Three hundred twenty-six women with PCOS and 50 age-matched and weight-matched ovulatory women. INTERVENTION(S) Ultrasound assessment of ovarian morphology in patients and controls and ovarian blood flow and fasting hormone levels in a subset of 50 patients and matched controls. MAIN OUTCOME MEASURE(S) Ovarian morphological assessments, ovarian blood flow by pulsatility index (PI) and resistance index (RI), and measurements of gonadotropins, estrogen, sex hormone-binding globulin, androgens, inhibin B, glucose, and insulin. RESULT(S) Using strict ultrasound criteria, 195 woman (60%) had enlarged ovaries, 135 (35%) had normal ovarian size but characteristic morphology, and 16 (5%) had normal size and morphology. Ovarian blood flow was increased (reduced PI and RI) in PCOS. All hormonal parameters were elevated in PCOS. Ovarian size correlated only with insulin and a measure of insulin resistance. Ovarian blood flow correlated positively with insulin, T, free T, and E2 but not with luteinizing hormone. Inhibin B showed a negative correlation with ovarian blood flow. CONCLUSION(S) When a clinical diagnosis of PCOS was made, virtually all women were found to have characteristic ovarian morphology. Insulin correlated with increased ovarian size as well as with increased blood flow. Blood flow also correlated positively with sex steroids but negatively with inhibin B.

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
BACKGROUND Frequent endocrine disorders have been reported after allogeneic stem-cell transplant, but data on adult survivors of autologous transplants are still scarce. METHODS In this prospective study we investigated early (at 3 months) and late (at 12 months) endocrine dysfunctions in 95 consecutive autologous stem-cell transplant recipients (47 men and 48 women) aged 16 to 55 years. The functions of the hypothalamic-pituitary-gonadal/thyroid/adrenal/somatotroph axis were evaluated. RESULTS Three months after the transplant, insulin-like growth factor-1 values were below the normal range in 53 patients (56%); 37 of 40 women (93%) of reproductive age experienced precocious ovarian failure; 39 of 46 men (85%) showed high follicular stimulating hormone, and 17 men (37%) showed low testosterone levels. Adrenal insufficiency occurred in 28 patients (30%) during the peritransplant period after corticosteroid withdrawal. Transient subclinical hyperthyroidism was found in 15 patients (16%). Transient "low T(3)" syndrome was revealed in 29 patients (31%). Twelve months after the transplant, insulin-like growth factor-1 values were still low in 36 patients (38%). Menstrual cycles resumed in four women; follicular stimulating hormone, luteinizing hormone, and estradiol levels improved in 10 patients. Testosterone was low in only two men (4%). Seminal analysis revealed azoospermia in 32 (91%) of 35 men examined. Subclinical hypothyroidism was found in 11 patients (12%); eight of them had previously received radiotherapy for the upper half of the body. CONCLUSION This study documents frequent endocrine disorders during the first year after autologous stem-cell transplant. Despite a tendency to improve, in more than half of the cases, the complications persisted for more than 1 year. Therefore, to diagnose and correct early and late endocrine dysfunctions, endocrine screening is required during the first year in all patients undergoing autografting.

Abstract
OBJECTIVE To evaluate the effectiveness of gonadotropin-releasing hormone agonists (GnRH-a) with or without coadministration of tibolone in women with menstrual cycle-related irritable bowel syndrome (IBS). DESIGN Prospective, randomized, placebo-controlled clinical trial. SETTING Universities of Catanzaro and Naples. PATIENT(S) One hundred twenty young premenopausal women with menstrual cycle-related IBS (Rome II criteria). INTERVENTION(S) Administration of leuprolide acetate depot (LAD, 11.25 mg IM/3 months) plus tibolone (group A), LAD plus placebo tablets (group B), and injection of a placebo solution plus placebo tablets (group C). MAIN OUTCOME MEASURE(S) Severity of bowel symptoms or signs of IBS and quality of life (QoL), at baseline and after 6 months of treatment. RESULT(S) In all groups, the mean scores for each symptom or sign of IBS and for QoL were significantly improved after treatment. A significant difference was observed between group C and groups A and B. No difference between these last groups was detected in symptoms or signs of IBS. The QoL scores were significantly higher in group A than in group B. CONCLUSION(S) Gondotropin-releasing hormone agonist administration is effective in women with menstrual cycle-related IBS. The addition of tibolone does not reduce effectiveness compared with agonist alone and increases QoL.

Abstract
BACKGROUND Adipocytokines are produced by adipose tissue and have been thought to be related to insulin resistance and other health consequences. We measured leptin, adiponectin, and resistin simultaneously in women with polycystic ovary syndrome (PCOS) and age- and weight-matched controls. Our hypothesis was that these simultaneous measurements would help determine whether adipocytokine secretion is abnormal in PCOS independent of body mass and whether these levels are related to insulin resistance as well as other hormonal changes. METHODS Fifty-two women with PCOS and 45 normal ovulatory women who were age- and weight-matched were studied. Blood was obtained for adipocytokines (leptin, adiponectin, and resistin) as well as hormonal parameters and markers of insulin resistance as assessed by the quantitative insulin-sensitivity check index. Body mass index (BMI) was stratified into obese, overweight, and normal subgroups for comparisons between PCOS and controls. RESULTS Adiponectin was lower (P < 0.05) and resistin was higher (P < 0.05) while leptin was similar to matched controls. Breakdown of the groups into subgroups showed a strong body mass relationship for leptin with no changes in resistin although adiponectin was lower in PCOS, even controlling for BMI. In controls, leptin and adiponectin and leptin and resistin correlated (P < 0.05) but not in PCOS. In controls, all adipocytokines correlated with markers of insulin resistance but not in PCOS. CONCLUSIONS When matched for BMI status, decreased adiponectin in PCOS represent the most marked change. This alteration may be the result of altered adipose tissue distribution and function in PCOS but no correlation with insulin resistance was found.

Abstract
Osteoporosis is a common disorder, especially among elderly post-menopausal women. Elderly women are often affected by co-morbidities, impaired gastrointestinal function and reduced mobility; therefore, the treatment strategy for their osteoporosis can be difficult. In this randomized pilot study, we have investigated the effects of a 12-month treatment with neridronate on bone mineral density (BMD), bone turnover markers and quality of life (QoL). The study included 40 women (age, 65-80 yr; post-menopausal period, >15yr) from a single osteoporosis centre. Twenty women received a monthly im injection of 25 mg of neridronate associated with a daily dose of 500 mg of calcium and 400 U of vitamin D. Twenty women received calcium plus vitamin D supplements alone. Changes in BMD at the lumbar spine and femoral neck were measured by dual energy X-ray absorptiometry. Serum type I collagen C-telopeptide (sCTX), urinary free-deoxypyridinoline (ufDPD), bone alkaline phosphatase (ALP) and serum osteocalcin levels were determined. For the QoL assessment, the Italian version of the SF-36 test was administrated. Spine and hip BMD rose by 6.6 +/- 3 and 4.2 +/- 2.3%, respectively (p < 0.05), after 12 months of neridronate treatment. Markers of skeletal turnover significantly fell already after 3 months of neridronate treatment and decreased progressively thereafter within 12 months. The mean decrease at 12 months ranged from 38 +/- 11% for sCTX to 25.2 +/- 15% for ufDPD (p < 0.001, all). The mean improvement in QoL in the treated group was 45.7% for bodily pain, 37.5% for general health perception, 23.1% for vitality, 18% for emotional role functioning and 12% for physical role functioning. The changes observed in BMD, turnover markers and QoL in the untreated group were ns. The intermittent neridronate administration was easily manageable and well tolerated. In conclusion, neridronate currently represents a valid option for the treatment of osteoporosis, since it helps just as much as oral BPs in the improvement of BMD and in particular conditions it can be even more effective.

Abstract
White blood cell (WBC) count is a known risk factor for atherosclerotic vascular disease in adult women. Polycystic ovary syndrome (PCOS) is potentially a risk factor for atherosclerosis and cardiovascular disease. The aim of the present study was to investigate leukocyte count in PCOS. One hundred and fifty PCOS women matched for age and body mass index with 150 healthy women were enrolled. WBC count, C-reactive protein, and a complete anthropometrical, metabolic, and hormonal evaluation were performed in both groups. Serum insulin, glucose level, and lipid profile were also measured in each subject. WBC count was significantly higher (P < 0.0001) in PCOS with (interquartile range in parentheses) 7260 (393) cells/mm(3), compared with controls with 5220 (210) cells/mm(3). C-reactive protein levels were significantly increased (P < 0.0001) in PCOS with 2 (1) mg/liter compared with healthy women with 0.7 (0.8) mg/liter. In both groups, there was a significant (P < 0.0001) linear correlation between WBC count and homeostasis model assessment score (PCOS, r = 0.94; controls, r = 0.91). Multiple linear regression analysis showed that other hormone levels are not predictors of leukocyte count both in PCOS and control women. In conclusion, our data demonstrate that PCOS women have an increased WBC count that correlates with homeostasis model assessment values.

Abstract
OBJECTIVE(S) To compare the long-term effectiveness of two different laparoscopic colposuspension procedures. STUDY DESIGN Sixty women affected by genuine stress incontinence (GSI) were enrolled in a prospective randomized controlled trial (RCT) and treated by transperitoneal laparoscopic colposuspension using nonabsorbable sutures (group A) or prolene mesh fixed with tackers or staplers (group B). In each group the subjective and objective failure rates were evaluated at 12, 24, and 36 months after surgery. For the subjective evaluation patients were asked whether they had experienced urine leakage and any urine loss they reported was recorded on a visual analogue scale (VAS). The objective evaluation was performed by means of a clinical examination and multichannel urodynamic studies. The data were analyzed by the intention-to-treat method. RESULTS The subjective failure rate was significantly (P < 0.05) lower in group A than in group B at 12 months (3.3% versus 13.3%, respectively), 24 months (20.0% versus 36.7%, respectively), and 36 months (33.3% versus 53.3%, respectively) after surgery. The objective failure rate also differed significantly (P < 0.05) between the two groups after 12 (10.7% versus 25.0% for group A and group B, respectively), 24 (29.6% versus 57.7%, respectively), and 36 (42.3% versus 61.5%, respectively) months of follow-up. CONCLUSION(S) Laparoscopic colposuspension performed with sutures is more effective than laparoscopic colposuspension accomplished with the use of prolene meshes in the long term, and the use of prolene meshes should be avoided in treatment of GSI.

Abstract
At present, it is unclear what the role is of laparoscopic ovarian diathermy (LOD) and of metformin administration as second-line treatments for ovulation induction in women with polycystic ovary syndrome (PCOS) after failure of clomiphene citrate (CC) treatment. The aim of the present study was to compare in a randomized double-blind placebo-controlled fashion the effectiveness of LOD with metformin administration in the treatment of CC-resistant women with PCOS. A total of 120 overweight primary infertile anovulatory CC-resistant women with PCOS were enrolled and randomized into two groups of treatment. Group A underwent diagnostic laparoscopy, whereas group B underwent LOD. At hospital discharge, the patients were treated for 6 months with metformin cloridrate (group A; 850 mg twice daily) or with multivitamins (group B). The ovulation, pregnancy, abortion, and live-birth rates were evaluated. At the end of the study, the total ovulation rate was not statistically different between both treatment groups (54.8 vs. 53.2% [correction] in groups A and B, respectively), whereas the pregnancy (21.8 [correction] vs. 13.4%), the abortion (9.3 [correction] vs. 29.0%), and the live-birth (86.0 [correction] vs. 64.5%) rates were significantly (P < 0.05) different between the two groups. Our data show that metformin administration is more effective than LOD in overall reproductive outcomes in overweight infertile CC-resistant women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine metabolic diseases and is characterized by obesity in approximately 50% of those affected. Adiponectin is an adipocyte-derived protein that possesses an antiatherosclerotic action and improves insulin sensitivity. Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) regulates the transcription of several adipocyte-specific genes. The aim of this study was to investigate the putative influence of the PPAR-gamma gene Pro12Ala polymorphism on the adiponectin levels in PCOS and healthy women. One hundred twenty women with PCOS and 120 healthy women whose ages and body mass indexes matched those of the PCOS patients were investigated. The genetic analysis of PPAR-gamma gene Pro12Ala polymorphism was performed by restriction fragment of polymorphisms. Serum adiponectin levels were evaluated, and the homeostasis model assessment score was also calculated. No subject was homozygous for the Ala12 allele of the PPAR-gamma gene. No significant differences in body mass index, plasma glucose and lipid levels, and homeostasis model assessment scores were observed between and within genotype groups in PCOS and control women. No significant differences in serum adiponectin concentrations were observed between and within genotype groups in PCOS and control women. In conclusion, our results confirm that adiponectin concentrations are similar in PCOS and controls and demonstrate no effect of the PPAR-gamma gene Pro12Ala polymorphism on serum adiponectin levels.

Abstract
OBJECTIVE To evaluate the effectiveness of the injection of bupivacaine plus epinephrine before laparoscopic myomectomy. METHODS Sixty premenopausal women with uterine leiomyomata were enrolled in a randomized controlled design and intraoperatively treated with injection of bupivacaine plus epinephrine (group A) or saline solution (group B) during laparoscopic myomectomy. Uterine size and volume, number of leiomyomata, hematological parameters, total operative time, enucleation time of each myoma, suturing time of the myomectomy, blood loss, degree of surgical difficulty, and postoperative pain were evaluated. Just before and after the injection of vasoconstrictive or saline solution, systolic and diastolic blood pressure and heart rate were recorded in each subject. RESULTS Blood loss, total operative and enucleation time, and degree of surgical difficulty was significantly (P <.05) lower in group A than in group B. No difference was observed between groups in suturing time of the myomectomy. The number of vials of pain medication used postoperatively was significantly (P <.05) lower in group A than in group B. No differences in systolic and diastolic blood pressure or heart rate was recorded between the 2 groups. CONCLUSION The injection of bupivacaine plus epinephrine during laparoscopic myomectomy is effective in reducing blood loss, total operative and enucleation time, degree of surgical difficulty, and postoperative pain.

Abstract
Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases affecting women of fertile age, and is characterized by hyperandrogenism, chronic anovulatory cycles and oligomenorrhea or amenorrhea. Given the repercussions of chronic anovulation on sterility, PCOS is a heavy social burden. Here we describe the procedures used to induce ovulation in PCOS patients, the surgical approach and medical treatments that are still being experimented.

Abstract
The aim of this study was to evaluate the presence of early vascular damage in young normal-weight women with polycystic ovary syndrome (PCOS). Thirty young normal-weight women with PCOS, who had no additional metabolic or cardiovascular diseases, and 30 healthy women (controls) matched for age and body mass index were studied. A complete hormonal assay was performed in each subject. Serum insulin and glucose levels were measured at baseline and after the oral glucose tolerance test. Plasma endothelin-1 levels and serum lipid profile were also assessed. The endothelial function was studied by flow-mediated dilation on the brachial artery, and arterial structure was evaluated by intima-media thickness measurement using Doppler ultrasound of both common carotid arteries.A significant (P < 0.05) difference in flow-mediated dilation (14.3 +/- 1.9% vs. 18.1 +/- 2.0% for PCOS patients and controls, respectively) and in intima-media thickness (0.53 +/- 0.09 mm vs. 0.39 +/- 0.08 mm for PCOS patients and controls, respectively) was found between PCOS and control subjects. Serum endothelin-1 levels were also significantly (P < 0.05) higher in PCOS patients compared with controls (1.1 +/- 0.4 pmol/liter vs. 0.5 +/- 0.2 pmol/liter for PCOS patients and controls, respectively).In conclusion, our data show that young, normal-weight, nondyslipidemic, nonhypertensive women with PCOS have an early impairment of endothelial structure and function.

Abstract
To evaluate the cardiovascular risk of polycystic ovary syndrome (PCOS), we investigated lipid profile, metabolic pattern, and echocardiography in 30 young women with PCOS and 30 healthy age- and body mass index (BMI)-matched women. PCOS women had higher fasting glucose and insulin levels, homeostasis model assessment score of insulin sensitivity, total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels, and TC/high density lipoprotein cholesterol (HDL-C) ratio and lower HDL-C levels than controls. Additionally, PCOS women had higher left atrium size (32.0 +/- 4.9 vs. 27.4 +/- 2.1 mm; P < 0.0001) and left ventricular mass index (80.5 +/- 18.1 vs. 56.1 +/- 5.4 g/m(2); P < 0.0001) and lower left ventricular ejection fraction (64.4 +/- 4.1 vs. 67.1 +/- 2.6%; P = 0.003) and early to late mitral flow velocity ratio (1.6 +/- 0.4 vs. 2.1 +/- 0.2; P < 0.0001) than controls. When patients and controls were grouped according to BMI [normal weight (BMI, >18 and <25 kg/m(2)), overweight (BMI, 25.1-30 kg/m(2)), and obese (BMI, >30 kg/m(2))], the differences between PCOS women and controls were maintained in overweight and obese women. In normal weight PCOS women, a significant increase in left ventricular mass index and a decrease in diastolic filling were observed, notwithstanding no change in TC, LDL-C, HDL-C, TC/HDL-C ratio, and TG compared with controls. In conclusion, our data show the detrimental effect of PCOS on the cardiovascular system even in young women asymptomatic for cardiac disease.

Abstract
STUDY OBJECTIVE To assess the long-term effectiveness of presacral neurectomy (PSN) in women with severe dysmenorrhea due to endometriosis treated with conservative laparoscopic surgical intervention. DESIGN Randomized, controlled trial (Canadian Task Force classification I). SETTING University-affiliated department of obstetrics and gynecology. PATIENTS One hundred forty-one sexually active women of reproductive age. INTERVENTION Conservative laparoscopic surgery without (group A) or with (group B) PSN. MEASUREMENTS AND MAIN RESULTS At entry and 24-months after surgical procedures, cure rates; frequency and severity of dysmenorrhea, dyspareunia, and chronic pelvic pain; and quality of life were evaluated. At follow-up visit, the cure rate was significantly (P<0.05) higher in group B (83.3%) than in group A (53.3%). The frequency and severity of dysmenorrhea, dyspareunia, and chronic pelvic pain were significantly (P<0.05) lower in both groups compared with baseline values, and only severity was significantly (P<0.05) lower in group B. A significant (P<0.05) improvement in quality of life was observed after surgery in both groups and was significantly (P<0.05) increased in group B compared with group A. CONCLUSION PSN improves long-term cure rates and quality of life in women treated with conservative laparoscopic surgery for severe dysmenorrhea due to endometriosis.

Abstract
BACKGROUND Our aim was to evaluate the long-term effectiveness and safety of GnRH agonist plus raloxifene administration in women with symptomatic uterine leiomyomas. METHODS Fifty pre-menopausal women with uterine leiomyomas were treated with leuprolide acetate depot at dose of 3.75 mg/28 days and raloxifene hydrochloride at 60 mg/day for 18 cycles. At admission and after each six cycles of treatment, bone mineral density (BMD), uterine, leiomyoma and non-leiomyoma dimensions, serum bone metabolism markers, lipid, glucose and insulin levels were evaluated. Leiomyoma-related and climacteric-like symptoms were assessed using a daily diary. RESULTS Throughout the study, no significant change in BMD or in any bone metabolism markers was observed. A significant decrease in uterine, leiomyoma and non-leiomyoma sizes was detected in comparison with baseline already after 6 months. No other significant change was observed at the successive follow-up visits. No significant change in lipid and glucose profile was detected throughout the study. The treatments were well tolerated. All treatment withdrawals (16%, eight out of 50) were due to lack of compliance, and none to drug-related adverse experiences. CONCLUSION GnRH agonist plus raloxifene administration is an effective and safe treatment for pre-menopausal women with uterine leiomyomas.

Abstract
BACKGROUND Renal transplantation (RT) is the most common solid organ transplant procedure. Several studies have reported on gonadal function in male and female RT recipients with controversial results. METHODS Forty consecutive patients (20 male, 20 female) with a fully functioning allograft (serum creatinine 0.8-1.3 mg/dl) for at least 15 months after RT were included in the study. Their ages ranged from 23 to 44 years (median 38) and their post-RT follow-up lasted 15-86 months (median 23). FSH, LH, prolactin, 17-beta-estradiol, testosterone, androstenedione and dehydroepiandrostrone were determined in all patients and compared with a group of 80 healthy subjects. Pelvic ultrasonography was performed in all participants. RESULTS Testosterone was below the normal range in 70% of male patients and within the lowest third in the remainder; a lack of LH increase indicated an inhibition of the reproductive axis. Male testosterone values were negatively influenced by calcineurine inhibitors treatment (P < 0.005), but positively influenced by a better graft function (P < 0.0001). Testicular and prostate volumes were reduced with respect to controls, with the latter related to circulating testosterone levels. Ten of the women (50%) had menstrual cycle disorders after RT, three being affected by transient, and three by persistent, amenorrhea. Another two patients had had transient polymenorrhea. In four women (20%), a premature ovarian failure was diagnosed. No relationship was found between female reproductive function and age, graft function or duration of the post-transplant period. Prolactin was lower in patients on calcineurin inhibitors (P < 0.01). CONCLUSIONS Abnormalities of the reproductive system were frequent after successful RT in both genders.
