RESUMO
OBJECTIVE: To reappraise the anatomic distribution of endometriosis lesions in cases with Superficial Implants (SI), Ovarian Endometrioma (OMA) and Deep Infiltrating Endometriosis (DIE). MATERIALS AND METHODS: A prospective observational study was operated between January 1989 to June 2009. A total of 1333 consecutive patients with a laparoscopic diagnosis of endometriosis, were extracted from our database. Due to missing data or repeated operations, 232 patients were excluded from the study. Finally, 1101 patients who met the selected criteria were included in the present analysis.. Primary outcome of study was the anatomic location of endometriotic lesions. Secondary outcomes were laterality of lesions as well as location of adhesions. RESULTS: Mean age of patients was 33.06 years (range 15-63 years) while the mean BMI was 21.5. The ovary was the most frequent site of endometriotic lesions (737 patients, 66.94%) followed by the utero-sacral ligaments (USL) (45.51%), the ovarian fossa (32.15%), the pouch of Douglas (29.52%) and the bladder (21.25%). Deep Infiltrating Endometriosis (DIE) was diagnosed in 159 patients (14.4%) with an increasing rate starting from the mid-nineties. The left side was predominant for all locations except fromr ovarian SI and fallopian tube, but for this latter location the number of cases was limited. 600 (54.4%) patients had adhesions wjth the adnexa being the most frequent site of location (47.4%). CONCLUSIONS: Ovary was the main site of endometriotic lesions followed by the utero sacral ligaments. Left side was predominant for all locations except for ovarian SI and fallopian tube. The diagnosis of DIE has constantly being increased since mid-nineties. The large cohort of patients included in the study has strengthened previous reported data.

To study the outcome of FISH sperm examination in cases with sperm pathology and outline the potential correlation with certain chromosomal defects. A retrospective study of prospectively collected data was performed in IAKENTRO, Infertility Treatment Center. Rates of abnormal FISH semen examination were compared between male infertility patients and fertile controls. Detection of abnormal FISH semen examination as well as each chromosomal abnormality detected was correlated with each sperm deficiency (asthenozoospermia, oligozoospermia and teratozoospermia) in a univariate regression model. There were 72 male partners included, of which 52 male infertility patients and 20 controls. The rate of abnormal sperm FISH examination was significantly higher in patients' group (55.8% vs. 15.0% for controls, p = .002). Asthenozoospermia, oligozoospermia and teratozoospermia were significantly correlated with detection of abnormal FISH examination (p = .004, p = .01 and p < .001 respectively). Teratospermia was significantly correlated with increased aneuploidy rate for chromosome 17 (p = .005), chromosome X (p = .05) and Y (p = .03). FISH examination reveals pathology in a significant proportion of patients with sperm defects and should be recommended to achieve early detection of chromosomal defects that may postpone favourable reproductive outcome.

OBJECTIVE: It was previously shown that higher concentrations of myo-inositol in human follicular fluid improve oocyte and embryo quality, whereas D-chiro-inositol seems to worsen oocyte quality and ovarian response in polycystic ovary syndrome patients. Our study was the first one aiming to test whether different myo-inositol and D-chiro-inositol concentration in follicular fluids correlate with blastocyst quality in healthy young women. PATIENTS AND METHODS: Eight egg donors and eleven couples undergoing in vitro fertilization, were involved in a prospective observational study. Myo-inositol/D-chiro-inositol ratio was calculated in the follicular fluids and associated with different blastocyst grades. Donors were homogeneous and followed the same standard stimulation protocol. RESULTS: The ratio between myo-inositol and D-chiro-inositol was significantly higher in the specimens rated as good quality blastocysts, compared to those rated as poor-quality blastocysts. In this study, almost all the transferred blastocysts were graded as good quality and were correlated to lower D-chiro-inositol content in the follicular fluid; the implantation rate and pregnancy rate were satisfying. Our data suggest that the reduction of such ratio in follicular fluid seems to play a negative role in follicular development. CONCLUSIONS: We found a correlation between myo-inositol/D-chiro-inositol ratio in follicular fluid and blastocyst quality. The value of this ratio may represent a new biomarker for estimating the good features of blastocysts, and a prognostic factor of embryo implantation and pregnancy success. Moreover, the pre-treatment with myo-inositol in women undergoing in vitro fertilization (IVF) may improve oocyte quality and ART outcome. CLINICAL TRIAL REGISTRATION NUMBER: NCT03055442 (ClinicalTrials.gov registry).

AIM: The aim of this paper was to evaluate the effectiveness of sublingual use of misoprostol in women undergoing first trimester surgical abortion. Special consideration was given in a sub-group analysis according to parity. METHODS: A retrospective study was conducted, enrolling patients during 2006-2009. Pregnancies less than 12 weeks of gestation were exclusively included. Our sample was divided in: group 1, in which we included women who had received 400 mcg of misoprostol sublingually two hours before surgical abortion and group 2, with no use of misoprostol. Cervical dilatation and estimated blood loss (EBL) were compared between the two groups. Moreover, a sub-group analysis of the former parameters was made separately in nulliparous and multiparous women. RESULTS: Out of 79 patients included, 48 (60.75%) received misoprostol, while 31 (39.25%) did not. Cervical dilatation was significantly higher in group 1 (6.4±2.1 mm vs. 4.7±1.7 mm in group 2, P=0.001), while EBL was significantly lower in the same group (105.0±22.1 mL vs. 120.3±24.2 mL for group 2, P=0.005). Concerning the sub-analysis, cervical dilatation was significantly increased and EBL was significantly lower in multiparous receiving misoprostol comparing with those who did not (P=0.001 and P=0.002, respectively). However, the same parameters did not differ significantly between the two sub-groups of nulliparous women. CONCLUSION: Sublingual administration of 400mcg misoprostol is effective concerning cervical ripening and EBL in women undergoing first trimester surgical abortion. According to the results of the present clinical trial prostaglandin E1 is more effective in multiparous group of women.

Vitrification has been successfully applied in the cryopreservation of oocytes and embryos. It can be achieved either by direct (open system) or indirect (closed system) contact with liquid nitrogen. Unlike embryo vitrification, few reports have been published regarding oocyte vitrification in closed systems. In order to validate the effectiveness of a closed and aseptic vitrification approach for oocyte cryopreservation, a prospective, randomized study was performed. Sibling oocytes donated from the same donor were randomly and equally assigned into closed or open vitrification groups. A total of 75 vitrification-warming cycles were performed in each group. Apart from the survival rate (82.9% versus 91.0%, P<0.05), no statistically significant differences were observed in pregnancy (ß-human chorionic gonadotrophin positive) (42.7% versus 33.3%), clinical pregnancy (36.0% versus 28.0%), implantation (13.8% versus 10.1%), ongoing pregnancy (33.3% versus 24.0%) and live birth (36.0% versus 24.0%) rates between the closed and open groups, and 27 and 18 healthy babies were born, respectively. This study shows that the replacement of the open vitrification system by a closed system has no impact on clinical pregnancy and implantation rates. Therefore, the closed vitrification system provides an aseptic alternative to the open method for oocyte vitrification.

The use of open carriers for embryo vitrification has raised safety concerns and therefore vitrification in closed systems has been proposed. However, the drop in the cooling rate emerges as a major drawback. The objective of the present study was to compare the efficiency of vitrification in open versus closed conditions. Blastocysts were randomly allocated either to open ultra-rapid vitrification (group I) or closed aseptic vitrification (group II). In group I, blastocysts were exposed to two solutions of ethylene glycol/dimethylsulphoxide (10%/10% and 20%/20%), while in group II, blastocysts were pretreated with a solution of lower concentration (5%/5%). A total of 208 and 224 vitrification-warming cycles were performed for groups I and II, respectively. Both groups were equal in terms of maternal age, sperm parameters and number and quality of blastocysts vitrified, warmed and transferred per cycle. Importantly, there was no significant difference between the groups in the analysed outcomes; embryo survival rate (84.1% versus 82.1%), clinical pregnancy rate (45.9% versus 42.4%), implantation rate (25.6% versus 24.5%), cycle cancellation rate (6.7% versus 8.5%) and live birth rate (41.2% versus 41.0%). These data suggest that ultra-rapid vitrification may be replaced by aseptic vitrification without affecting clinical efficiency.

OBJECTIVE: The aim of this prospective randomized controlled cross sectional study was to evaluate the effect of a six month tibolone treatment in healthy postmenopausal women on biochemical CVD markers by calculating the changes of the blood serum levels of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (Tg), high-sensitivity C-reactive protein (hsCRP), homocysteine (Hcy), and endothelin-1 (ET-1) at the beginning of the treatment and after six months. MATERIALS AND METHODS: Fifty-two healthy postmenopausal women were enrolled in a prospective, randomized, case-controlled outpatient trial. Group 1 (n = 26) received 2,5 mg/d tibolone for six months, while Group 2 (n = 26) received no treatment. Serum levels ofTC, LDL, HDL, Tg, hsCRP, Hcy, and ET-1 were evaluated at baseline and after six months. RESULTS: The two groups did not statistically differ at baseline characteristics. In Group 1 tibolone treatment decreased significantly TC (p = 0.01), HDL (p < 0.001), and Tg (p < 0.001) serum levels while a significant increase ofhsCRP (p < 0.001) was observed. Finally no changes were noticed on LDL, Hcy, and ET-1 serum levels. Regarding Group 2, no changes were observed. CONCLUSION: Short-term tibolone treatment in healthy postmenopausal women exerts a mixed action, acting beneficially in some markers (TC, LDL, Tg, Hcy, and ET-1) where as detrimentally in others (HDL, hsCRP).

AIM: The aim of the study was to examine the impact of pre-eclampsia on neonatal outcomes of late preterm deliveries. METHODS: A retrospective study was conducted, enrolling pregnancies delivered between 34 0/7 and 36 6/7 weeks of gestation during the period 2004-2007 in a large tertiary center. Pregnancies were divided in group 1, including those complicated with pre-eclampsia and group 2, including normotensive cases. Epidemiological characteristics, mode of delivery and complications contributing in late preterm delivery were initially studied. Neonatal morbidity parameters of our interest included mean Apgar score in the 1st and 5th minute, admission to Neonatal Intensive Care Unit (NICU) and need for emergency intubation. Intrauterine growth retardation (IUGR), low birth weight (LBW) and very LBW (VLBW), respiratory distress syndrome (RDS), hypoglycemia, NICU infection, abnormal cerebral ultrasonographic findings and duration of NICU residence were also compared between the two groups. RESULTS: Out of 363 late preterm pregnancies, 29 (8%) were delivered because of pre-eclampsia. Mean gestational week and birth weight were significantly lower in group 1. The rate of elective caesarean section was also significantly higher in this group. The same observation was made concerning rates of IUGR, LBW and VLBW neonates. Furthermore, incidence of NICU admission and hypoglycemia were significantly higher in the group of infants born by pre-eclamptic mothers. Incidence of RDS and cerebral echo pathology were also higher, but without significant difference when compared to group 2. CONCLUSION: Neonatal adverse outcomes were increased in late preterm infants of pre-eclamptic women in comparison with those of normotensive women.

PURPOSE OF INVESTIGATION: Amniocentesis-related adverse outcomes in singleton pregnancies and possible risk factors for fetal loss after mid-trimester amniocentesis performed in a single institution were investigated. METHODS: Amniocentesis-related adverse outcomes such as insufficient aspiration of amniotic fluid (AF), repeated puncture, and aspiration of hemorrhagic AF after mid-trimester amniocentesis were reviewed, while special consideration was given according to the placental location. Fetal loss rate up to 24 weeks of gestation and risk factors related to fetal losses were also investigated. RESULTS: 5,948 cases with the inclusion criteria were analyzed. Advanced maternal age was the most common indication (53%) for amniocentesis. A need for repeated puncture was overall 2.1% (n = 128) and was associated with a fundal placental location. Aspiration of hemorrhagic amniotic fluid was observed in 3.7% (n = 222) and was significantly associated with an anterior or fundal placental position. Fetal loss rate was 0.3% and there was no relationship with advanced maternal age (> or = 35 years), gestational age at amniocentesis > 18 weeks, repeated procedure, aspiration of hemorrhagic AF or placental location. CONCLUSION: Anterior or fundal placental position is a risk factor for amniocentesis-related adverse outcomes, however without significant contribution to the fetal losses. Placental location, advanced maternal age, amniocentesis gestational age > 18 weeks, and the procedure's adverse outcomes seem to have no impact on fetal loss rate.

PURPOSE OF INVESTIGATION: The objective of the study was to examine the impact of parity on pregnancy outcomes in women 35 years and older. METHODS: The study was a retrospective cohort of singleton pregnancies of women aged > or = 35 years old during the period 2004-2008. Women were divided in two groups: group 1 included primigravidas and group 2 those with at least one past labor. Epidemiological characteristics, obstetric and neonatal outcomes were analyzed using the t test and chi-square test. RESULTS: 816 out of 5834 (14%) cases involved women aging > or = 35 years, 234 (28.7%) of which were nulliparous and 582 (61.3%) multiparous. Rate of cesarean section was 2.4 fold higher for primigravidas (p < .0001). Fetal distress, prolonged labor and Neonate Intensive Care Unity (NICU) admission were also significantly higher in group 1. CONCLUSION: Adverse pregnancy outcomes were increased in primigravidas of 35 years and older compared to multigravidas of the same age.

PURPOSE OF INVESTIGATION: We performed a randomized clinical trial to estimate whether preoperative use of misoprostol may reduce intraoperative blood loss of patients treated by minimally invasive surgery (MIS), such as laparoscopic (LM) or laparoscopically assisted myomectomy (LAM). METHODS: Sixty-seven menstruating patients with three or less myomas of a maximum diameter of 90 mm, scheduled for MIS, were randomly allocated to receive a preoperative single dose of intravaginal misoprostol or placebo. Sixty-four patients remained in the final analysis: 30 in the misoprostol (I) and 34 in the placebo group (II). Estimated blood loss (EBL), decline of postoperative hemoglobin (Hb) and side-effects of administered agent were the outcomes of main interest. RESULTS: The EBL was significantly higher in the placebo versus misoprostol group (217 +/- 74 vs 126 +/- 41, respectively). Similarly, the decline of postoperative Hb was significantly higher in group II (1.6 +/- 0.43) compared to group I (1 +/- 0.33). The operative time was comparable in both groups, while the rate of side-effects was similar between groups. CONCLUSION: The preoperative use of misoprostol in patients with uterine fibroids managed by minimally invasive surgery significantly reduces intraoperative blood loss. Misoprostol might be useful for the prevention of postoperative anemia in more extended minimal invasive interventions, such as myomectomy of large fibroids or laparoscopic hysterectomy.

BACKGROUND: Current obstetric practice is characterised by a continuous increase in caesarean section (CS) delivery rates. OBJECTIVE: Main purpose of our study was to estimate the overall and annual rates of CS in a University Hospital in Greece. METHODS: This was a retrospective chart review of all singleton pregnancies delivered by CS between 2004 and 2008 at a gestational age > 24 weeks. The overall and annual CS rates were calculated. The rate of elective (Group 1) and emergency CS (Group 2) , as well as the specific indications in the two groups of the study were also analyzed. RESULTS: Overall 5362 singleton pregnancies were delivered in the period of the study. The overall CS rate was 29.2% (n = 1564). The mean ±SD maternal age in years of the women delivered by CS was 29.65 ± 6.72 years, while it was 27.10 ±5.63 years for those who delivered vaginally (P<0.0001). The overall rates of elective and emergency CS were 18.2% and 11.0% respectively in the 5-year period of the study. The most common indication for an elective CS was a previous CS (63.1%), which remained almost stable during the period of the study. The main indication for emergency CS was foetal distress in the first three years of the study, while labour progress failure was the leading indication in the last two years. CONCLUSION: In this series, the overall CS rate was high. A previous caesarean delivery accounts for about one third of all cases and constitutes the leading indication for elective CS while foetal distress is the most common indication for an emergency caesarean section.

PURPOSE OF INVESTIGATION: The aim of the present study was to estimate the risk for breech presentation in women with singleton pregnancies at-term who had had at least one previous cesarean section (CS) versus at least one previous vaginal delivery. METHODS: Out of 4269 singleton pregnancies during the study period, 2008 met the inclusion criteria. The history, the number of previous CSs, as well as maternal age, parity, birth weight, gestational age, neonatal sex and placenta previa were used to estimate the risk for breech at term. RESULTS: The overall incidence of breech presentation was 3.2%, while 20% of the women had a history of at least one previous CS. The rate of breech presentation at term in singleton pregnancies after CS increased two-fold (5.3%) when compared to those with at least one previous vaginal delivery (2.6%), (p = 0.01) [OR 2.08 (95% CI, 1.23-3.52)], while the number of the previous CSs did not correlate with breech presentation (p = NS) [OR 0.86 (95% CI, 0.31-2.4)]. CONCLUSION: According to the present study, women with a history of at least one cesarean delivery have an increased risk for breech presentation in the subsequent singleton pregnancy at-term.

Polycystic ovary syndrome (PCOS) is a syndrome involving defects in primary cellular control mechanisms that result in the expression of chronic anovulation and hyperandrogenism. This syndrome has been for many years one of the most controversial entities in gynecological endocrinology. Polycystic ovary syndrome has been proven to be a familial condition. Although the role of genetic factors in PCOS is strongly supported, the genes that are involved in the etiology of the syndrome have not been fully investigated until now, as well as the environmental contribution in their expression. The heterogeneity of the syndrome entertains the mystery around this condition which concerns thousands of infertile women worldwide. Some genes have shown altered expression suggesting that the genetic abnormality in PCOS affects signal transduction pathways controlling steroidogenesis, steroid hormones action, gonadotrophin action and regulation, insulin action and secretion, energy homeostasis, chronic inflammation and others. The present review of the contemporary literature constitutes an effort to present all the trends in the current research for the etiology of polycystic ovary syndrome.
RESUMO
BACKGROUND: The rate of operative vaginal delivery has remained stable the last decade, however the rate of vacuum has increased against forceps application. Different maternal and neonatal outcomes have been proposed by many reports. The aim of the present study is to compare the short term maternal and neonatal outcomes between vacuum and forceps delivery. MATERIAL AND METHODS: We conducted a medical record review of live born singleton, vacuum and forceps-deliveries. Maternal and delivery characteristics were recorded. Maternal and neonatal outcomes were also assessed. Out of 7098 deliveries, 374 were instrument assisted, 324 were conducted by vacuum (86.7%) and 50 by forceps (13.3%). RESULTS: The incidence of 3rd degree lacerations and periurethral hematomas was similar between vacuum and forceps (3.4% vs. 2% and 0.3% vs 0% respectively), while perineal hematomas were more common in forceps compared with vacuum application (2% vs 0.3% respectively), albeit not significantly. The rate of neonates with Apgar scores
RESUMO
BACKGROUND: The association of ovarian malignancy with dermatomyositis (DM) is well established from previous reports, while the relationship with polymyositis (PM) is rare. CASE REPORT: We report a case of a 50 years old nulliparous woman who developed clear cell ovarian cancer four years after the PM diagnosis. The patient presented with deep lower abdominal pain and distension. CA-125 was elevated and the preoperative MRI showed pelvic tumor occupying the Douglas pouch. Exploratory laparotomy revealed a gross mass of clear cell ovarian carcinoma. CONCLUSION: Physicians must be alert of the possibility of malignancy in patients with a previous diagnosis of polymyositis.
RESUMO
Gestational diabetes mellitus and new-onset hypertension, which includes gestational hypertension and pre-eclampsia, are common complications of pregnancy. Many features of the insulin resistance syndrome have been associated with these conditions. These include glucose intolerance, hyperinsulinemia, hypertension, obesity, and lipid abnormalities. Other accompanying abnormalities may include elevated serum levels of leptin, TNFalpha, plasminogen activator inhibitor-1 and testosterone. The establishment of these features before the onset of gestational diabetes mellitus and hypertension in pregnancy suggests that insulin resistance or associated abnormalities may play a role in these disorders. These observations suggest that therapeutic interventions to reduce insulin resistance may lower the risk of both gestational diabetes mellitus and hypertension in pregnancy.
RESUMO
Conventional treatment of normogonadotropic anovulatory infertility is ovulation induction using the antiestrogen clomiphene citrate, followed by follicle-stimulating hormone. Multiple follicle development, associated with ovarian hyperstimulation, and multiple pregnancy remain the major complications. Cumulative singleton and multiple pregnancy rate data after different induction treatments are needed. Newer ovulation induction interventions, such as insulin-sensitizing drugs, aromatase inhibitors and laparoscopic ovarian electrocoagulation, should be compared with conventional treatments. Ovulation induction efficiency might improve if patient subgroups with altered chances for success or complications with new or conventional techniques could be identified, using multivariate prediction models based on initial screening characteristics. This would make ovulation induction more cost-effective, safe and convenient, enabling doctors to advise patients on the most effective and patient-tailored treatment strategy.
RESUMO
OBJECTIVE: The aim of this study is to present pregnancy and perinatal outcomes of twin gestations in older women and compare them with that for younger women. STUDY DESIGN: We conducted a retrospective cohort study of twin pregnancies in our department between 1988 and 2003. The women were classified into two groups by maternal age: women of age 35 years and older (study group) and women less than 35 years (control group). Population characteristics, complications during pregnancy and delivery, and neonatal outcomes were assessed. The Student's t-test, chi2 test, Fisher exact test, and binary logistic regression analysis were used to examine the relationship between maternal age and the different variables. RESULTS: A total of 238 twin pregnancies were enrolled (study group, 57 women; control group, 181 women). Spontaneous conceptions were significantly higher in the control group (P < 0.001), while conceptions after in vitro fertilization (IVF) were significantly higher in study group (P < 0.001). Mean figures of gestational age at delivery and birth weight for the older group did not differ significantly from the younger group. Although the antepartum and intrapartum complications were more common in the study group, they were not statistically significant compared to the control group. This was also true for the perinatal outcomes. Only the very low birth weight (VLBW < 1,500 g) rate was significantly higher in the study group. The number of perinatal deaths was similar on comparison by maternal age. CONCLUSIONS: Based on our study, advanced maternal age at twin gestation does not seem to affect significantly pregnancy complications and perinatal outcomes. VLBW was the only unfavorable perinatal outcome related to advanced maternal age.

BACKGROUND: The specific role of LH in folliculogenesis and oocyte maturation is unclear. GnRH antagonists, when administered in the late follicular phase, induce a sharp decrease in serum LH which may be detrimental for IVF outcome. This study was performed to evaluate whether the replacement of GnRH agonist (triptorelin) by a GnRH antagonist (ganirelix; NV Organon) in oocyte donation cycles has any impact on pregnancy and implantation rates. METHODS: A total of 148 donor IVF cycles was randomly assigned to use either a GnRH antagonist daily administered from the 8th day of stimulation (group I) or a GnRH agonist long protocol (group II) for the ovarian stimulation of their donors. The primary endpoints were the pregnancy and the implantation rates. RESULTS: The clinical pregnancy rate per transfer (39.72%, 29/73 versus 41.33%, 31/75) based on transvaginal scan findings at 7 weeks of gestation, the implantation rate (23.9 versus 25.4%) and the first trimester abortion rate (10.34 versus 12.90%) were similar in the two groups. CONCLUSION: In oocyte donation cycles the replacement of GnRH agonist by a GnRH antagonist appears to have no impact on the pregnancy and implantation rates when its administration starts on day 8 of stimulation.
